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.

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.

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.
