Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil tape silicon coating devices, in particular to an aluminum foil tape silicon coating device. Background Art

[0002] Aluminum foil tape uses high-quality pressure-sensitive adhesive with good viscosity, strong adhesion, anti-aging and other effects, which greatly improves the thermal insulation performance. Specifications include (0.05mm-0.08mm) various widths and lengths. Aluminum foil tape is used to paste the seams of all aluminum foil composite materials, seal the puncture points of insulation nails, and repair damaged areas. It is the main raw and auxiliary material for refrigerator and freezer manufacturers, and is also a must-buy raw material for insulation material distribution departments.

[0003] After searching, a Chinese patent with publication number CN216322763U discloses an aluminum foil tape silicon coating device, which can be used to flatten aluminum foil tapes of various specifications by adjusting the position of the adjusting roller. The aluminum foil tape silicon coating device has a reasonable structure, is convenient for collecting bulk silicon powder, has high economic benefits, and can evenly flatten the silicon powder on the surface of the aluminum foil tape, thereby improving production efficiency and facilitating use. However, this device cannot be limited according to aluminum foil tapes of different widths. In the process of silicon coating aluminum foils of different widths, it is easy to cause the position of the aluminum foil tape on the adjusting roller to shift due to uneven force. The position of the aluminum foil tape in the box is shifted, which easily causes uneven silicon coating and reduced tape efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

When the first extrusion roller 8 rotates, the first extrusion roller 8 drives the corresponding first bidirectional screw 9 to rotate, and one end of each first bidirectional screw 9 is fixedly connected with a runner. By rotating the runner, the first extrusion roller 8 is restricted so that the first bidirectional screw 9 can rotate in the corresponding first extrusion roller 8, and the outer surface of each first bidirectional screw 9 is threadedly connected with two first limiting plates 10, and the inner wall of each first limiting plate 10 is slidably connected with the corresponding first extrusion roller 8. Specifically, the rotation of the first bidirectional screw 9 will drive the corresponding two first limiting plates 10 to move horizontally opposite or in reverse along the corresponding first extrusion roller 8, so as to limit the aluminum foil tape according to different widths.

[0024] In a preferred embodiment, the inner wall of the box body 1 is rotatably connected to a second extrusion roller 16, and the inner wall of the second extrusion roller 16 is rotatably connected to a second bidirectional screw 17.

One end of the second bidirectional screw 17 is fixedly connected to a rotating wheel. When the rotating wheel is rotated, the rotating wheel will drive the second bidirectional screw 17 to rotate. At this time, the rotation of the second bidirectional screw 17 will not drive the second extrusion roller 16 to rotate. The rotation of the second bidirectional screw 17 will drive the two second limit plates 18 to move in the opposite or reverse direction along the second extrusion roller 16, so as to adjust according to the width of the aluminum foil tape at the discharge port.

[0025] like Figure 1 、 Figure 2 As shown, a first motor 2 is fixedly installed on the outer surface of the box body 1, and a third bidirectional screw 4 is provided on the front and rear sides of the box body 1. The output end of the first motor 2 is fixedly connected to one of the third bidirectional screws 4, and the third bidirectional screw 4 is perpendicular to the first bidirectional screw 9.

The transmission belt 6 is transmission-connected to the outer surfaces of the two transmission wheels 5. Specifically, the two transmission wheels 5 are connected by the transmission belt 6 so that the two third bidirectional screws 4 can rotate simultaneously.

[0027] In this embodiment, both ends of each first extrusion roller 8 are rotatably connected to a first connecting block 7, and the interior of the first connecting block 7 is provided with grooves that are perpendicular to each other and not at the same height.

The inner wall of each first connecting block 7 is threadedly connected to the corresponding third bidirectional screw 4, and the outer surface of each first connecting block 7 is slidably connected to the box body 1. Specifically, the rotation of the third bidirectional screw 4 will drive the corresponding first connecting block 7 to make the two first extrusion rollers 8 move in opposite or reverse directions along the third bidirectional screw 4 at the same time, so as to facilitate the two first extrusion rollers 8 to clamp aluminum foil tapes of different thicknesses.

Both ends of the third extrusion roller 15 are rotatably connected to the corresponding second connecting blocks 14, and the third extrusion roller 15 is connected to form a whole through the two second connecting blocks 14. The top end of each spring 13 is fixedly connected to the corresponding second fixed block 11, and the bottom end of each spring 13 is fixedly connected to the corresponding second connecting block 14. Specifically, when aluminum foil tapes of different thicknesses are pulled out from the discharge port, they are clamped by the mutual cooperation of the third extrusion roller 15 and the second extrusion roller 16.
