In the existing technology, the same coating mechanism as other plasters is used for coating gel. However, the texture of gel is different from that of plaster. During coating, the gel has poor fluidity and is not easy to be discharged from the discharge port, resulting in uneven gel coating and affecting product quality. Utility Model Content

[0005] Preferably, a motor for driving a rotating shaft is provided at the end of the coating box.

[0006] Preferably, a hydraulic cylinder is fixed on the top of the feed box, and the hydraulic cylinder drives the piston to move in the feed box.

[0012] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 It can be seen that a coating mechanism for the production of gel patches includes a coating box 1, brackets 2 are provided on both sides of the coating box 1, a rotating shaft 3 is provided inside the coating box 1, and spiral plates 4 with opposite rotation directions are provided at both ends of the rotating shaft 3. A plurality of discharge ports 5 are provided at the bottom of the coating box 1, and a feed box 6 is provided above the coating box 1. The two ends of the feed box 6 are connected to the two ends of the coating box 1 through a first pipe 7. A piston 8 is telescopically provided inside the feed box 6. The piston 8 divides the inside of the feed box 6 into two feeding areas. The two ends of the feed box 6 are connected to the barrel through a second pipe 9. The piston 8 moves in the feed box 6 to form a structure in which two feeding areas absorb gel from the barrel and transport the gel to the coating box 1.

[0014] When the utility model is used,

[0015] Connect the equipment and install it on the production line, feed the material into the feed box 6 with a barrel, start the equipment, and the piston 8 in the feed box 6 moves back and forth, so that the volume of the two feed areas inside the feed box 6 changes alternately. When one feed area becomes larger, gel is extracted from the barrel, and the feed box 6 on the other side transports gel into the coating box 1. The rotating shaft 3 in the coating box 1 drives the spiral plate 4 to rotate, and the gel is evenly dispersed in the coating box 1 and discharged from the discharge port 5. The non-woven fabric and other material strips pass under the discharge port 5. The gel is squeezed out under the pressure in the coating box 1 to ensure smooth discharge and thus ensure uniformity of the gel, avoiding uneven coating that affects product quality.

[0016] A motor 10 driving the rotating shaft 3 is provided at the end of the coating box 1. The motor 10 drives the rotating shaft 3 to rotate, so that the spiral plate 4 pushes the gel to move in the coating box 1. The direction of movement of the gel is from the two ends of the coating box 1 to the middle, so that the gel is evenly distributed.

[0017] A hydraulic cylinder 11 is fixed on the top of the feed box 6, and the hydraulic cylinder 11 drives the piston 8 to move in the feed box 6. The hydraulic cylinder 11 is connected to the piston 8, driving the piston 8 to reciprocate in the feed box 6, thereby realizing the feeding of the gel.

[0018] One-way valves are provided on the first pipe 7 and the second pipe 9. The flow direction of the gel in the first pipe 7 is from the feed box 6 to the coating box 1, and the flow direction of the gel in the second pipe 9 is from the barrel to the feed box 6. The one-way valve allows the piston 8 to only extract the gel in the barrel and transport it to the coating box 1 when moving in the feed box 6. The gel has fluidity in a single direction, ensuring smooth feeding and discharging of the gel, and generating pressure in the coating box 1 to ensure smooth discharge of the gel from the discharge port 5.

[0019] Compared with the prior art, the utility model has the following beneficial effects: by arranging a reciprocating piston in the feed box, continuous feeding of the gel is ensured, and a gel flow in a certain direction is formed to ensure smooth discharge of the gel, thereby ensuring product quality and avoiding uneven gel coating affecting product quality.
