接着剤ディスペンシングの効果に影響を与える要因は何ですか？ 日本

Kaiwei glue dispensers are widely used, and many industries have market demands for glue dispensers. Nowadays, some manufacturers often encounter this situation when using glue dispensers: the same machine equipment has completely different effects in different manufacturers, because there are many factors in the glue dispensing process that will have more or less impact on the glue dispensing, so we all need to understand which factors will affect the glue dispensing effect of the glue dispenser?

1. The size and stability of the glue dispensing pressure will affect the dispensing effect
After clarifying the appropriate nozzle and contact area, it is necessary to find the appropriate air pressure through multiple tests. If the standard air pressure is too high, it will cause glue to overflow, too much glue, too little pressure will cause intermittent glue delivery, poor actual glue dispensing effect, unstable standard air pressure will also cause uneven glue dispensing, etc. Therefore, the factory should maintain a stable and appropriate standard air pressure to ensure the actual effect of glue dispensing.

2. The viscosity of the glue will affect the dispensing effect
The viscosity is high, the glue is slow, and it is very easy to pull. If the viscosity is too low, the fluidity is strong, the glue becomes difficult to control, and it is very easy to lose glue. Therefore, choosing a suitable viscosity glue can also deal with the problem of glue efficiency. The packaged glue cannot have bubbles, otherwise it will cause part of the glue to crack and there will be no glue. Every time the rubber or plastic hose is replaced, the rubber or plastic hose should be accurately discharged to discharge the air in the cavity to ensure smooth glue delivery.

3. The appropriate distance between the needle and the contact surface of the dispensing machine will also affect the dispensing effect
Before each operation, the distance between the needle and the working surface must be calibrated, and the actual dispensing effect under different parameters must be checked. Experience is learned and the workshop layout is appropriately adjusted. Specialized personnel learn and train the operation and maintenance of mechanical equipment, and set up specialized personnel to be responsible for the operation of A and B glue dispensing equipment to ensure that more than 2 people understand the operation of mechanical equipment at the same time. In this way, if one of them leaves the operation booth, other members can immediately take up their posts to reduce the impact of personnel flow.
