work process:

Preparation before operation: put the prepared two liquid materials (triacetin solution and essence solution) into separate large liquid material tanks 31 respectively; open the atomization cover 1, and check the opened tow (acetic acid Whether the fiber tow) passes through the atomization device correctly, and whether the relevant parameter settings of the equipment meet the requirements of the filter rod process, start running after adjustment.

Operation process: In the liquid material supply system 3, the control system pumps the liquid material in the large liquid material tank 31 into the small liquid material tank 32 for constant temperature and constant liquid adjustment and control. The pressure pump 33 monitors the flow rate of the liquid material through the flow sensor 34, and then distributes and sprays it from the nozzle 23 through the distributor.

At the bottom of the atomization chamber A, the excess liquid material is introduced into the small liquid material tank 32 through the pipeline through the return interface 25, which can not only prevent the excessive liquid material in the atomization chamber A from affecting the normal operation of the nozzle 23 and other parts, but also can be recycled Use to reduce liquid waste and save production costs.

After spraying the triacetin solution, the tow 4 comes out from the outlet groove 22 of the atomizing chamber A and then enters the atomizing chamber B. The working process is the same as that in the atomizing chamber A, and will not be repeated here. The difference is that the sprayed liquid is an essence solution. The tow 4 comes out from the outlet groove 22 of the atomization chamber B after spraying the essence solution, and enters the subsequent forming process through the output roller 5.

During operation, the flow sensor 34 monitors the flow change in the pipeline and sends the signal to the control system for processing. When a nozzle is blocked or blocked, the liquid flow in the associated pipe will change, and the flow sensor 34 that detects the flow change sends a signal to the processor in the control system, and the processor determines the preset threshold value. The comparison determines that if the threshold value is exceeded, the processor sends an instruction to the host to make the host alarm and stop.

It is hinged with the atomizing chamber 2, which is convenient for the subsequent maintenance and repair of the atomizing chamber 2. The upper end of the inlet and outlet grooves are designed to be open, which is convenient for the installation of the tow. The inverted "V" top design of the atomizing cover 1 can collect , to divert small liquid droplets to reduce the drop of droplets and interfere with the quality of the tow; the design of the nozzle 23 close to the inlet groove 21 is convenient for the subsequent tow to remove the excess liquid material, and prevents the excess liquid material from accumulating on the output roller 5 outside the device, It ensures the smooth progress of the subsequent process; through the adjustable pressure oil pump, the supply pressure of the system is adjusted according to the process requirements of the liquid material, and the applicability of the device is improved.
