Description

Technical Field

[0001] This utility model relates to the technical field of roller coating equipment, specifically to an adhesive applicator for the production of silicone heating sheets. Background Technology

[0002] Silicone heating pads (SCS), also known as silicone rubber heating pads, are made of silicone rubber and glass fiber cloth, which are composed of two sheets of glass fiber cloth and double-layer silicone. Because it is a thin sheet product, it has good flexibility and can make complete and close contact with the object being heated. To ensure convenient use later, it needs to be adapted to an adhesive device for protection.

[0003] For example, Chinese utility model patent CN220310829U proposes a sheet metal roller coating machine. The roller coating machine body is equipped with a conveyor belt and a roller coating mechanism. One end of the roller coating mechanism is equipped with two sets of paint buckets. Two sets of auxiliary plates are fixedly connected to the inner side wall of the roller coating machine body. Adjusting plates are slidably connected to the two sets of auxiliary plates. Edge guards that cooperate with the conveyor belt are detachably connected to the adjusting plates. The roller coating machine body is equipped with an adjustment device for moving the adjusting plates, a cleaning device for cooperating with the conveyor belt, and a control mechanism.

[0004] Existing roller coating machines use conveyor belts to transport materials into the roller coating mechanism for adhesive application. However, existing machines have problems: during the adhesive application process, some adhesive flows into the gap between the conveyor belt and the housing, requiring regular manual cleaning. The gap between the conveyor belt and the housing is narrow, making cleaning difficult, and some adhesive also adheres to the surface of the conveyor belt, causing unevenness and resulting in uneven adhesive application. To address this, we propose an adhesive application device for silicone heating sheet production that can prevent adhesive from flowing into the gap and clean the conveyor belt.

[0030] This application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figures 1-5 This application provides an adhesive applicator for the production of silicone heating pads, characterized by comprising a roller coater body 100, a base 110 at the bottom of the roller coater body 100, a roller coater mechanism 120 on the roller coater body 100, an adhesive tank 130 on one side of the roller coater mechanism 120, a conveyor belt 150 on the inner side wall of the roller coater body 100, a servo motor 140 connected to one side of the drive roller of the conveyor belt 150, a blocking mechanism 200 on the top of the roller coater body 100, the blocking mechanism 200 including a mounting block 210 located at the top of the roller coater body 100, a screw 220 penetrating one side of the mounting block 210, a baffle 230 connected to the screw 220 by a bearing, a 240 on one side of the screw 220, and a cleaning mechanism 300 at the bottom of the roller coater body 100 on the side away from the roller coater mechanism 120.

[0032] During use, first turn on the servo motor 140 to drive the conveyor belt 150 for transmission, then turn on the roller coating mechanism 120. The glue enters the roller coating mechanism 120 from the glue tank 130 and flows out from the bottom of the roller coating mechanism 120. Then rotate the handwheel inside the roller coating mechanism 120. The screw connected to one side of the handwheel pushes the internal steel roller closer to the glue roller to control the flow of glue. After the glue thickness is suitable, adjust the blocking mechanism 200 so that the spacing of the baffles 230 is equal to that of the object to be coated. Then place the silicone sheet on one side of the glue tank 130. The silicone sheet follows the glue tank 130 for transmission and then passes through the roller coating mechanism 120 for glue coating. The silicone sheet is removed when it moves along one end of the conveyor belt (the roller coating mechanism is existing technology and will not be described in detail here).

[0033] In some embodiments, the screw 220 is a bidirectional screw, and there are two mounting blocks 210 and two baffles 230.

[0034] During use, the screw 220 is a bidirectional screw, and there are two mounting blocks 210 and two baffles 230. By rotating the handwheel, the two baffles 230 can be moved closer to one end, so that the two sides of the silicone sheet are brought closer together, preventing the glue from flowing out laterally.

[0035] In some embodiments, the cleaning mechanism 300 includes a base plate 310, the bottom of which is fixedly connected to the bottom of the base 110. A rotating rod 320 extends through one side of the base plate 310, a spiral rod 330 is provided on the rotating rod 320, and a scraper 340 is provided on the top of the spiral rod 330.

[0036] During use, a cleaning mechanism 300 is provided at the bottom of the roller coating machine body 100. When the conveyor belt 150 is driven to the side of the cleaning mechanism 300, the scraper 340 of the cleaning mechanism 300 is in close contact with the surface of the conveyor belt 150 to clean the residual glue on the surface.

[0037] In some embodiments, scraper 340 is an arc-shaped elastic scraper.

[0038] During use, scraper 340 is an arc-shaped elastic scraper. The contact line between the arc-shaped scraper and the conveyor belt 150 is distributed in a curve. Compared with a straight scraper, its pressure gradient is gentler, which can avoid wear of scraper 340 or scratches on the belt surface caused by excessive local pressure in the glue residue area.

[0039] In some embodiments, the scraper 340 has a groove at its bottom and the sliding rod 350 is provided at the top of the spiral rod 330. The scraper 340 and the sliding rod 350 are inserted and fixed together.

[0040] During use, the scraper 340 has a groove at the bottom and the top of the spiral rod 330 is equipped with a slide bar 350, which facilitates the replacement and movement of the slide bar 350.

[0041] In some embodiments, a floating mechanism 400 is provided on one side of the rotating rod 320. The floating mechanism 400 includes a collar 410, an opening at the top of the collar 410, through which a T-shaped rod 420 passes. A spring 430 is provided on one side of the T-shaped rod 420, and the rotating rod 320 is fitted inside the collar 410.

[0042] During use, a floating mechanism 400 is provided on one side of the rotating rod 320. When the scraper 340 cleans the conveyor belt 150, the conveyor belt 150 receives a force in the same direction as the movement of the servo motor 140, causing the rotating rod 320 at the bottom of the scraper 340 to have a tendency to rotate to one side. At this time, the collar 410 provided on one side of the rotating rod 320 has a tendency to rotate. The collar 410 drives the top T-shaped rod 420 to have a tendency to rotate. A spring 430 is provided on one side of the T-shaped rod 420. The rotating rod 320 is fixed on one side of the spring 430, and the spring 430 is provided on the other side. The spring 430 is squeezed and deformed by the rotation of the T-shaped rod 420, which dampens the force that causes the rotation tendency.

[0043] In some embodiments, a scraping mechanism 600 is provided on one side of the baffle 230. The scraping mechanism 600 includes a second spring 610. One end of the second spring 610 is provided with the baffle 230, and a scraper 630 is provided on one side of the second spring 610. The scraper 630 is hinged to the baffle 230 through a short rod 620.

[0044] During use, a small amount of glue flows from the bottom of baffle 230 to one side. This glue can be cleaned off the conveyor belt surface by a scraper 630 located on one side of baffle 230. A spring 610 is installed on one side of scraper 630, which is hinged to baffle 230. When baffle 230 moves, spring 610 pushes scraper 630 to rotate, thus cleaning the conveyor belt on one side of baffle 230.

[0045] In some embodiments, a first recycling tank 500 is provided on one side of the roller coating machine body 100, a second recycling tank 700 is inserted into one side of the roller coating machine body 100, and a handle 710 is provided on one side of the second recycling tank 700.

[0046] During use, the glue removed by the scraper 340 in the cleaning mechanism 300 flows down the scraper 340 into the recovery tank 500 located on one side of the roller coating machine body 100. The glue removed by the scraper mechanism 600 flows down the scraper 630 into the recovery tank 700 for recycling. The recovery tank 700 is plugged into the glue tank 130 and can be pulled out using the handle 710 on one side.
