Working principle of glue spreading machine

       Glue spreading machine is characterized by high speed and low sensitivity to glue viscosity. Now let's learn about the working principle of the glue spreading machine.

       First, compressed air is sent into the rubber bottle to press the rubber into the feed pipe connected to the piston chamber. When the piston is on the up stroke, the piston chamber is filled with glue; When the piston pushes the glue dropping needle downward, the glue is pressed out of the needle nozzle. Again, the amount of glue dripped is determined by the downward stroke distance of the piston, which can be adjusted manually or controlled in software.

 This is the introduction of the working principle of the glue spreading machine. The use of the glue spreading machine can improve the gluing speed, improve the gluing environment, improve the gluing quality, and improve the quality of plywood.

       In the daily operation process, the inspection and maintenance of the glue applicator shall be done well to ensure that the glue applicator is kept in good working condition. Check before startup. The operator must check the equipment according to the following steps before starting and operating the glue spreading machine each time:

      1. Whether the air source switch of the glue applicator is open, whether the air source pressure is greater than 3.5 bar, whether the air pressure has low pressure sensing alarm, and whether the glue applicator equipment cannot work normally.

       2. Check whether the air source pressure of the pneumatic motor of the glue feeder feed pump is within the set value, whether the air pressure of the single column lifting frame is within the set value, and whether the manual valve is pressed under the pressure plate.

       3. Check whether the air supply pressure of the adhesive regulator of the glue spreading machine is consistent with the set value, or the rubber wire lattice does not meet the requirements of the regulator of the pressure reducing valve.

       4. Check whether the connection parts of the delivery pipe of the plunger pump and the coating valve are loose to prevent the air from eroding the adhesive and hardening the adhesive.

       5. Check the silicone oil cup of plunger rod of plunger pump and the sealing of piston rod of coating valve for silicone oil, and replenish it in time.

      6. The power supply of the glue applicator is correctly and firmly connected, and the input voltage of the equipment is 220V, 50Hz.

      7. Check whether the face value of silicone oil in the dry silicone oil on the surface of the glue spreading machine is higher than that of the adhesive, and timely supplement.

      8. Confirm that the air source switch of the pneumatic motor of the glue applicator is turned on, and confirm that the switch is turned on before turning on the power.
