The leakage of rubber valve of automatic dispenser often occurs after the valve is closed. 95% of this situation is due to the small diameter of the needle used.
Connect the air valve: connect the air out port of the dispensing controller to the syringe through the air pipe, and connect the needle cylinder air valve to airin of the dispensing controller.
Generally, the glue mixing degree and glue on-off can be determined by controlling the length of mixing pipe and controlling the pressure bar of automatic dispensing machine. The mixing mode of mixing pipe is static mixing, which is composed of a series of left and right rotating blades arranged vertically in the casing pipe. Glue a and B are continuously cut and overlapped when passing through the mixing pipe to form a uniform mixture. The outlet of the mixing tube can be connected with an adapter, which is convenient to use any diameter needle to ensure the accurate glue output.
After the needle cylinder is put into the needle holder and fixed, the air valve can be connected. Connect the air out port of the dispensing controller to the syringe through the air pipe, and connect the needle cylinder air valve to airin of the dispensing controller. Connect the "dispensing" interface of dispensing machine to the signal input interface of dispensing controller through cable. Pedal connection: connect the foot pedal to the "running" interface of the dispenser to control the operation of the dispenser. Z-axis cable connection: connect the z-axis cable plug with the "z-axis" of the dispenser.
If the needle is too small, it will affect the flow of liquid and cause back pressure. As a result, the phenomenon of drip will be formed soon after the rubber valve is closed. If the needle is too small, it will affect the exhaust bubble action when the rubber valve starts to use. As long as the larger needle is replaced, this problem can be solved.
The conical oblique needle produces the least back pressure and the most smooth liquid flow.
液体内空气在胶阀关毕后会产生滴漏现象, 最好是预先排除液体内空气, 或改用不容易含气泡的胶.或先将胶离心脱泡后在使用.瞬间胶( 快干胶 ) 在胶阀接头及管路上堵塞此种情形主要因过多的湿气或重复使用过的瞬间胶. 应确保使用新鲜的瞬间胶. 将管路以未含湿气的Aceton丙酮彻底清洗过. 使用的空气应确定完干燥且于厂内空压与胶阀系统间加装过滤器. ( 以上方法如仍然无效, 则应使用氮气. )
The air in the liquid will leak after the rubber valve is closed. It is better to remove the air in the liquid in advance, In this case, it is mainly due to excessive moisture or repeated use of instant glue. Make sure to use fresh instant glue. Clean the pipeline thoroughly with aceton acetone without moisture The air used should be dried and a filter should be installed between the air pressure system and the rubber valve system in the plant. (if the above method still fails, nitrogen should be used.)
It should be noted that the handheld programmer is selected to the interface on the left side of the dispenser through the serial port line. 6. If the type of the dispenser connector used is the same as that of the dispenser, the "dispensing" and "running" interfaces of the dispenser can be seen according to the number of cores of the connector, two core dispensing and three core operation.
