Description

Technical Field

[0001] This utility model relates to the field of filter membrane production technology, and in particular to a filter membrane production coating equipment. Background Technology

[0002] Coating is a technique that involves applying a slurry to a product and is widely used in fields such as composite material production and lithium-ion battery production.

[0003] Chinese Patent Application No. 202121509469.X discloses a coating apparatus comprising: a first roller including a first outer peripheral surface; a trough for holding slurry and including a discharge port facing the first roller; a shielding member including a first end connected to the discharge port, the shielding member being used to shield at least a portion of the first outer peripheral surface to limit the coating range of the slurry in the axial direction of the first roller; and a doctor blade including a cutting edge extending along the axial direction of the first roller, the cutting edge abutting against the shielding member, thereby solving the problem in the prior art that the width of the slurry layer obtained by the coating process cannot be adjusted;

[0004] Although the above solutions address the problem that the coating range of the slurry on the material is usually determined by the width of the discharge port of the coating device, which makes the coating range of the slurry on the material fixed and difficult to match with actual production needs, the above solutions also have the problem of difficulty in automatically detecting and feeding the coating box. Therefore, when feeding is needed, manual feeding is required, which can easily lead to material interruption and uneven feeding, thereby reducing work efficiency. Therefore, a filter membrane production coating equipment is proposed. Utility Model Content

[0005] To address the above problems, this utility model proposes a filter membrane production coating equipment, comprising:

[0006] A chassis, and a material bin fixedly installed on one side of the chassis;

[0007] A coating roller, the two sides of which are movably connected to the inner wall of the machine housing;

[0008] A fixing rod, the two ends of which are also fixedly installed on both sides of the inner wall of the machine housing, the fixing rod being located above the coating roller;

[0009] A coating box is fixedly installed on the outer side wall of the fixing rod, and one side of the coating box is in contact with the outer side wall of the coating roller;

[0010] A slot plate is snapped onto the top of the coating box, and a spray pipe is fixedly installed on one side of the slot plate;

[0011] A liquid pump is fixedly installed on one side of the material box, and the output end of the liquid pump is fixedly connected to the input end of the spray pipe through a hose.

[0012] A first liquid sensor is fixedly installed on the inner side wall of the coating box;

[0013] A second liquid sensor is also fixedly installed on the inner wall of the coating box, and the second liquid sensor is located on one side of the first liquid sensor.

[0014] Furthermore, the input end of the liquid pump extends into the interior of the hopper, and the liquid pump is electrically connected to the first liquid sensor and the second liquid sensor respectively through a controller.

[0015] Furthermore, a feed pipe is fixedly installed on the top of the hopper, and a sealing cap is threadedly connected to the top of the feed pipe.

[0016] Furthermore, a stirring rod is provided inside the material box, and a motor is fixedly installed on one side of the material box. The output end of the motor extends into the inside of the material box and is fixedly connected to one end of the stirring rod.

[0017] Furthermore, a sliding plate is fixedly installed on the top of the chassis, and a slider is slidably connected inside the sliding plate.

[0018] Furthermore, a screw is provided inside the slide plate, and a motor is fixedly installed on one side of the slide plate. The output end of the motor extends into the interior of the slide plate and is fixedly connected to one end of the screw.

[0019] Furthermore, the outer wall of the screw is threadedly connected to the slider, and a swing rod is fixedly installed at the bottom of the slider.

[0020] Furthermore, power rollers are fixedly installed on both sides of the inner wall of the chassis, and the power rollers are located on one side of the coating roller. Multiple transmission rollers are also fixedly installed on both sides of the inner wall of the chassis, and the multiple transmission rollers are located on one side of the chassis.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] When the second liquid sensor fails to detect any paint inside the coating box, the information is transmitted to the controller. The controller then activates the pump to extract paint from the hopper. The extracted paint is then transported through a hose to the nozzle and sprayed out. The sprayed paint flows back into the coating box until the first liquid sensor detects the paint and transmits the information to the controller. The controller then stops the pump, thus achieving automatic feeding. The added paint contacts and adheres to the coating roller. As the filter membrane rotates past the coating roller, the filter membrane is coated. This technical solution facilitates automatic feeding of the coating box and improves coating efficiency.
