[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: an aluminum foil tape silicone coating device, including a silicone storage box 1. Two sets of symmetrical first connecting frames 2 are welded and fixedly connected to the upper parts of both sides of the silicone storage box 1. Vertical sliding grooves are provided inside the first connecting frames 2. Upper lifting blocks 5 and lower lifting blocks 3 are slidably connected within the sliding grooves of the first connecting frames 2. The upper lifting blocks 5 and lower lifting blocks 3 are clearance-fitted with the sliding grooves to ensure smooth vertical sliding. A coating roller 4 is rotatably connected between the two lower lifting blocks 3 via deep groove ball bearings. The lower part of the coating roller 4 is immersed in the silicone liquid in the silicone storage box 1, and can carry the silicone liquid when rotating. A connecting rod 6 is bolted and fixed between the two upper lifting blocks 5. Four sets of rotating arms are rotatably connected to both sides of the connecting rod 6 via needle roller bearings. 7. The two sets of outer rotating arms 7 and the two sets of inner rotating arms 7 face opposite directions and are symmetrically distributed in a figure-eight shape. The two sets of rotating arms 7 on the same side are rotatably connected by a pressure rod 8 through a deep groove ball bearing. The axis of the pressure rod 8 is parallel to the axis of the glue roller 4 and is used to adhere to the surface of the tape. Fixing plates 9 are fixed on both sides of the connecting rod 6 by welding. The two sets of outer rotating arms 7 and the lifting block 5 are fixedly connected by an outer torsion spring 10 through a hook and a slot. The two sets of inner rotating arms 7 and the fixing plates 9 are fixedly connected by an inner torsion spring 10 through a hook and a slot. Both the outer torsion spring 10 and the inner torsion spring 10 are sleeved on the outside of the connecting rod 6. The torsion spring 10 provides a pre-tightening force so that the pressure rod 8 always elastically presses the tape, achieving flattening at the glue application point. The front upper lifting block 5 and lower lifting block 3 are threaded with a first threaded rod 11. The first threaded rod 11 is rotatably connected to the upper and lower bearing seats of the first connecting frame 2 through a thrust bearing. The rear upper lifting block 5 and lower lifting block 3 are slidably installed with a first sliding rod 12. The first sliding rod 12 is fixed to the upper and lower ends of the first connecting frame 2 by welding, and plays a guiding role to prevent the upper lifting block 5 and lower lifting block 3 from deviating when sliding. A second connecting frame 13 is welded to the upper part of the silicon storage box 1 on the side away from the first connecting frame 2. A transverse groove is formed on the inner side of the second connecting frame 13, and two sets of moving blocks 14 are slidably connected within the groove. A parallel roller 15 is rotatably connected between the two moving blocks 14 via a deep groove ball bearing. The parallel roller 15 supports the conveyor belt. A third connecting frame 18 is welded to the middle of the opposite side of the two sets of second connecting frames 13. A vertical groove is formed on the inner side of the third connecting frame 18, and a lifting plate 19 is slidably connected within the groove. The gap between the lifting plate 19 and the groove is matched. The upper part of the lifting plate 19 is fixed with a scraper 20 by bolts. The blade of the scraper 20 faces the coating roller 4 and is used to scrape off excess silicone liquid. A third threaded rod 21 is installed on the front side of the lifting plate 19. The third threaded rod 21 is rotatably connected to the upper and lower bearing seats of the third connecting frame 18 through a thrust bearing. A third sliding rod 22 is slidably installed on the rear side of the lifting plate 19. The third sliding rod 22 is fixed to the upper and lower ends of the third connecting frame 18 by welding and plays a guiding role. Rotating the third threaded rod 21 can drive the lifting plate 19 to move up and down, change the gap between the scraper 20 and the coating roller 4, and control the coating thickness. The front movable block 14 has a second threaded rod 16 installed inside. The second threaded rod 16 is rotatably connected to the bearing seats at both ends of the front second connecting frame 13 through a thrust bearing. The rear movable block 14 has a second sliding rod 17 slidably connected inside. The second sliding rod 17 is fixed to both ends of the rear second connecting frame 13 by welding, and plays a guiding role to prevent the movable block 14 from deviating when sliding. The threads on the first threaded rod 11 and the second threaded rod 16 are opposite in direction, which can control the upper lifting block 5, the lower lifting block 3, and the two sets of moving blocks 14 to move in opposite directions at the same time. Four sets of mounting plates 23 are fixedly connected to the upper part of the left and right sides of the silicon storage box 1 by welding. Two sets are symmetrically arranged on the side of each set. The first positioning roller 24 is rotatably connected between the two sets of mounting plates 23 on the front side by a deep groove ball bearing. The second positioning roller 25 is rotatably connected between the two sets of mounting plates 23 on the rear side by a deep groove ball bearing. The upper surfaces of the first positioning roller 24 and the two sets of parallel rollers 15 are flush with each other and lower than the upper surface of the coating roller 4, so that the tape can adhere to the coating roller 4 to obtain the silicone liquid. The lower surface of the second positioning roller 25 is higher than the upper surface of the parallel rollers 15, forming a curved transmission path of "first positioning roller 24, coating roller 4, parallel roller 15, second positioning roller 25", ensuring that the tape is always in a taut state and avoiding slippage.

[0017] Working principle: When this utility model is used, the aluminum foil tape substrate is wound from below the first positioning roller 24, passes above the coating roller 4, and then wound to below the parallel roller 15. The tape adheres to the outer circle of the coating roller 4 and is finally led out from below the second positioning roller 25 to the subsequent process. Silicon liquid addition: Add silicon liquid to the silicon storage box 1, ensuring that the lower part of the coating roller 4 is immersed in the silicon liquid; Pressure adjustment: Rotate the first threaded rod 11 to drive the upper lifting block 5 and the lower lifting block 3 to rise and fall synchronously, adjust the pressure of the pressure rod 8 and the coating roller 4 on the tape, and ensure that the tape is not deformed and the silicone liquid is not leaked. Rotate the second threaded rod 16 to drive the two sets of moving blocks 14 to move in opposite directions, and the parallel roller 15 to stretch the tape in opposite directions synchronously until there is no looseness on the tape surface, ensuring that the surface of the part of the tape directly opposite the scraper 20 is flat. Thickness adjustment: Rotate the third threaded rod 21 to drive the lifting plate 19 to move up and down, and adjust the gap between the scraper 20 and the coating roller 4; Start-up and operation: After the entire equipment is driven, the coating roller 4 carries the silicone liquid and rotates to apply the silicone liquid to the lower surface of the tape. The pressure rod 8 elastically presses the tape under the action of the torsion spring 10, flattening the coating area. The scraper 20 scrapes off the excess silicone liquid on the surface of the coating roller 4 to ensure uniform coating thickness. The tape is guided out by the second positioning roller 25, and the bending path maintains tension to avoid slippage.
