Carton pressure resistance

The main factors that affect the compressive strength of cartons are: ① raw material quality; ② moisture; ③ box type and flute type; ④ printing and opening; ⑤ processing technology.

a. Raw material quality

The kellicutt formula is used to calculate the compressive strength of cartons based on the ring crush strength of corrugated cardboard, which is an indicator of the compressive strength of cartons. The ring pressure strength is the bonding strength between the core paper and the surface paper or lining paper. The raw material is the main factor affecting the ring pressure strength. It is related to the quantity, tightness, moisture, etc. of the raw material. The grades of containerboard paper and corrugated base paper mainly include A, B, C, D, E, etc. Under normal circumstances, the grade matching principle should be followed when selecting materials. The grade selection of containerboard paper and corrugated base paper should be similar. At the same time, the boxboard The basis weight of paper and corrugated base paper should be maintained within the range of 21, so as to ensure the overall quality level of raw materials and the quality of corrugated board. Of course, corrugated board is volatilized by the surface paper, core paper and lining paper bonded together, so the factors of adhesive and core paper should also be considered. The appropriate moisture content, tightness and uniformity of the core paper are conducive to the adhesion with the surface paper and lining paper. The good adhesive performance of the adhesive and the appropriate thickness of the adhesive layer are conducive to improving the compression resistance of the corrugated box. strength.

B.Moisture

The production environment, storage environment, use environment, weather, climate and other factors of the cartons will all affect the moisture content of the cartons. In order to ensure the compressive strength of the cartons, the impact of the external environment on the water content of the cartons should be avoided as much as possible.

The initial moisture content of corrugated base paper will directly affect the board-making quality of corrugated cardboard. If the moisture content is high, the base paper will be soft, but the tensile strength will be relatively reduced; if the moisture content is low, the base paper will be dry, and the top of the corrugated corrugated board will easily crack during corrugation. In the production of corrugated cardboard, the moisture content required to obtain the best strength value is generally 6% to 8%. The traditional method of determining moisture is the drying and weighing method at 105°C, using an oven and a balance. This method is the standard method.

C. Box type and corrugated type

Box type refers to the type of box and the size ratio of boxes of the same type, which have a significant impact on compressive strength. Some cartons are made of double-layer corrugated cardboard, and their compressive strength is significantly higher than that of single-layer boxes of the same specifications. Under the same conditions, the higher the box, the worse the stability and the lower the compressive strength.

In people's consciousness, they often think that the larger the flute type, the higher the compressive strength of the carton, and it is easy to ignore the impact of the flute type on the deformation. The larger the flute type, the greater the compressive strength and deformation of the carton; the smaller the flute type, the smaller the compressive strength and deformation of the carton. If the carton is too large, but the flutes are very small, the carton will be easily stained during the compression test; if the carton is too small, but the flutes are very large, the deformation will be too large during the compression test, and the buffering process will be long and effective. The deviation between the force value and the final force value is too large.

D. Printing and opening

Printing will cause certain damage to corrugated cardboard, which will reduce the compressive strength of the carton. The size of the pressure and the size of the bearing area are a major factor affecting the compressive strength of the carton. If the printing pressure is too high, the corrugations will easily be crushed and the flute height will be reduced. Especially when printing at the pressure line, in order to force and clear printing at the pressure line, the entire cardboard will be crushed and the compressive strength of the carton will be greatly reduced. Therefore, printing here should be avoided as much as possible. When printing graphics and text on the full page or around the carton, in addition to the pressing effect of the impression roller on the corrugated cardboard, the ink also wets the paper surface, which in turn reduces the compressive strength of the carton. When a general carton is fully printed, its compressive strength drops by about 40%.

For products that require ventilation in packaging, opening holes on the box surface or punching handle holes on the side of the box will reduce the strength of the carton, especially if the opening area is large or biased to one side, etc., the impact will be more obvious.

E. Processing process deviation

Through experiments, it was found that under the same conditions, for every 1mm widening of the transverse pressure line of the carton, the compressive strength of the carton decreases by 90N-130N, and the deformation increases by about 2mm. If the pressure line is too wide, the force value of the carton will increase slowly during the 1 compression test, the effective force value will be small, and the final deformation will be large. In order to ensure the compressive strength, we should try our best to improve the production process and reduce the impact of each process on the compressive strength of the carton. Improper crimping during the box making process, too deep grooves, weak bonding, etc. will also reduce the compressive strength of the box.

Characteristic Composition And Working Principle Of Multihead Weigher

Source of multihead weigher

In the 1970s, the Japanese Agricultural Association asked weighing companies to weigh green peppers. In Japan, green pepper is usually packaged in bags in the form of quantitative packaging in supermarkets, if each bag of green pepper quantitative value is 120 grams, it is very difficult to fill 120 grams. As a single green pepper weight is heavier, and the difference is larger, less related to the interests of consumers, more related to the cost of the enterprise. The traditional way is manual weighing, that is, weighing on a static electronic scale, add up to 115 grams of green pepper one by one, and then it is almost impossible to find a 5 grams of green pepper to add, you must take a smaller green pepper from 115 grams, and add another larger green pepper. If the weight is much more than 120 grams or less than 120 grams, the above work needs to be repeated, so the weighing efficiency is very low, and it is difficult to achieve close to the target weight (quantitative value) results. After a lot of investigation and research, the technical personnel successfully solved the weighing problem of green pepper by using the combination weighing principle. Some large food enterprises will be its designated equipment.

Composition of multihead weigher

The basic composition of the combined scale is: main vibration plate, main vibration machine, line vibration plate, line vibration machine, hopper, weighing bucket, chute, hopper (optional), stepping motor, driving board, module conversion device, main control board.

Working principle of multihead weigher

1. The material is sent to the storage hopper by the material conveyor. When the material is added to the pre-set horizontal position, the electronic eye on the side of the storage hopper detects and sends out a signal to make the conveyor stop feeding until the material level on the storage hopper drops to the preset horizontal position, and then the electronic eye sends out the feed signal;

2.The material in the storage hopper, through the vibration of the main vibration machine to make the material from the main vibration plate evenly into the line vibration plate, to feed the line vibration plate;

3.The vibration of the line vibrator causes the material to be discharged from the line vibrator and into the hopper for storage;

4.When the weighing bucket completes the last weighing and emptying, the upper hopper is opened to make the material enter the weighing bucket for weighing. The output signal is transmitted to the motherboard of the control device through the lead wire. The CPU on the motherboard reads and records the weight of each weighing bucket, and then selects the combination weighing bucket closest to the target weight through calculation, analysis and combination.

5.When the feeding signal is allowed, the CPU issues a command to start the driver to open the selected weighing bucket, the material is sent through the chute into the hopper or directly into the packaging machine, and the feeding signal has been sent to the packaging machine to complete the weighting packaging system.

How to solve glue gun leakage

1. Glue leakage at the Hot melt gluing nozzle

If glue leaks from the nozzle during glue spraying, the possible reasons are as follows:

a. The temperature of the glue gun is not enough. The temperature of the hot melt glue gun should be increased appropriately.

b. If the pressure or flow rate of the air jet is too small, glue will drip from the nozzle. Increase the pressure of the air blowing pipe appropriately.

c. If the air passage in the nozzle is blocked, remove the nozzle module and clean it.

2. If glue leaks from the nozzle when the machine is not spraying glue, the possible reasons are as follows:

a. The thimble does not completely close the glue channel, and it is necessary to increase the pressure on the air channel of the solenoid valve of the glue gun.

b. The ejector pin is damaged and needs to be replaced.

c. The ejector pin and the outlet of the glue channel do not cooperate well. Adjust the fine-tuning bolt on the ejector pin to press down on the ejector pin and then loosen the bolt. Manually operate the solenoid valve on the glue gun several times.

3. The small hole in the middle of the needle valve leaks glue.

a. The sealing ring underneath the needle valve needs to be replaced.
