The dispensing quality of high-speed dispensing machine is mainly affected by the amount of glue, as well as dispensing machine. Lack of glue will lead to insufficient glue point strength, easy to cause components off, off. Too much glue can cause unnecessary bonding between components and even leave glue on the points. On the glue head, the next step is dispensing. Therefore, reasonable control of drug dosage is particularly important. So what methods do dispensers generally use to control the dispensing amount of high-speed dispensers? The following highlights several important factors that affect allotment.
First, the glue temperature. High speed dispenser can control the viscosity of glue by controlling the temperature of glue. Generally speaking, the greater the viscosity of glue, the greater the flow resistance, the less the amount of glue. It can be seen that the viscosity of glue has a great influence on the performance of dispensing. Because the glue material of the glue dispenser and spray paint machine can not be modified after selection, the glue dispenser manufacturer is generally controlled by the temperature of the glue.
Second, fluid pressure. Dispensing machine manufacturers mainly through the control of fluid pressure to control the dispensing speed of high-speed dispensing machine. Generally speaking, the greater the fluid pressure, the more glue through the valve port, the more glue, the faster the glue. However, due to the limitation of the valve port itself, the amount of glue will not change with the fluid. The pressure builds up and builds up indefinitely.
Third, the injection pressure. Injection pressure is the key to control the dispensing machine to spray glue line. The higher the injection pressure, the thinner the glue line. The higher the spray pressure, the stronger the glue of the dispensing machine and the glue of the dispensing machine, but as a liquid glue, it is easy to fly away, which will lead to the small droplets sprayed to the non-dispensing position, and the dispensing fails. The quantity of high-speed dispensing machine not only affects the quality of dispensing, but also reflects the key index of the professional level of dispensing machine manufacturers. Dispensing machine is in the stage of in-depth development in automation, the dispensing amount control technology has its own standards, so there is no need to worry too much about the related factors affecting the dispensing amount.
