Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil processing equipment, in particular to an aluminum foil reverse penetration, wrinkle removal and transmission device. Background Art

[0002] In the packaging industry, materials such as hard aluminum, soft aluminum foil or aluminum-containing composite film are often used. These materials are used as printing substrates, coating substrates or composite film substrates. These materials are either placed on the first unwinding or the second unwinding. After the first unwinding or the second unwinding, they will flow to the rewinding section. These materials must pass through the guide roller group of the equipment when they are in the unwinding and rewinding sections. In order to ensure that the materials always run in a straight line, the key film material tension generation and control sections such as the rewinding, unwinding section, tension output section, tension feeding section and printing section must apply a certain tension to the above film materials to ensure that the materials run in a straight line. Otherwise, the material will have no tension on the guide roller, and the material will deviate, which will cause the material to be soft and wrinkled at the least, or dead wrinkled at the worst, and eventually the wrinkled material will be scrapped.

[0003] In the related art, during the transmission of the aluminum foil by the guide roller, since the material in the unwinding and winding parts must be packaged with a certain tension, if the aluminum foil film material swings due to various reasons, the taut aluminum foil film material will produce upward protruding wrinkles on the winding shaft due to the swinging of the material, and the pressure roller on the winding shaft cannot flatten these protruding wrinkles. As the winding shaft is continuously wound, the protruding wrinkles on the winding shaft are continuously superimposed and accumulated, and the aluminum-containing material will burst due to severe deformation, causing the aluminum foil film material close to the core to be scrapped. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an aluminum foil reverse threading and wrinkle removal transmission device, which can stretch the aluminum foil film material and flatten the raised wrinkles by reversely threading the aluminum foil film material through a guide roller group or a pressure roller to ensure product quality.

[0005] According to the first aspect of the utility model, the aluminum foil reverse-threading and wrinkle-removing transmission device includes a frame, an unwinding assembly, a guide assembly and a winding assembly. The unwinding assembly is connected to the frame and is used to unwind the aluminum foil film material. The unwinding assembly includes an unwinding roller and an unwinding reverse-threading member. The unwinding reverse-threading member is adjacent to the unwinding roller and includes 3 unwinding reverse-threading rollers that are spaced apart and staggered in the upper and lower positions to guide the aluminum foil film material to move in an "S" shape. The guide assembly is connected to the frame and is located on the other side of the unwinding reverse-threading member away from the unwinding roller. The guide assembly includes a plurality of guide reverse-threading rollers, and the plurality of guide reverse-threading rollers are spaced apart from each other and staggered in the upper and lower positions to guide the moving direction of the aluminum foil film material and guide the aluminum foil film material to move in an "S" shape. The winding assembly is connected to the frame and is used for winding the aluminum foil film material. The winding assembly includes a winding roller and a winding reverse threading member. The winding reverse threading member includes three winding reverse threading rollers. The three winding reverse threading rollers are spaced apart and arranged alternately in upper and lower positions to guide the aluminum foil film material to move in an "S" shape and wind up on the winding roller.

[0006] The aluminum foil reverse-threading and wrinkle-removing transmission device according to the embodiment of the utility model has at least the following beneficial effects: the winding reverse-threading roller, the unwinding reverse-threading roller and the guide reverse-threading roller all guide the aluminum foil film material to take an "S"-shaped route, so that one side of the material contacts and fits with the surface of the guide roller. When the material runs to the next guide roller, the other side of the material contacts and fits with the surface of the guide roller. The purpose is to allow the surface of the second guide roller to contact the tip of the raised wrinkles with the surface of the guide roller, which plays a role in flattening the raised wrinkles, so that the raised wrinkles that appear on the first guide roller are flattened when encountering the second reverse-threading guide roller. This is the wrinkle-removing effect of the aluminum-containing substrate through the "S"-shaped guide roller group. By reverse-threading the aluminum foil film material through the guide roller group or the pressure roller, the aluminum foil film material is stretched and the raised wrinkles are flattened to ensure product quality.

[0007] According to some embodiments of the present invention, the winding reverse roller located close to the winding roller abuts against the winding roller to press the aluminum foil film material.

[0008] According to some embodiments of the utility model, a connecting shaft is provided between the winding reverse-threading rollers at both ends along the horizontal direction, and the winding reverse-threading roller located in the middle along the horizontal direction is connected to the connecting shaft.

[0022] In the related art, during the transmission of the aluminum foil by the guide roller, since the material in the unwinding and winding parts must be packaged with a certain tension, if the aluminum foil film material swings due to various reasons, the taut aluminum foil film material will produce upward protruding wrinkles on the winding shaft due to the swinging of the material, and the pressure roller on the winding shaft cannot flatten these protruding wrinkles. As the winding shaft is continuously wound, the protruding wrinkles on the winding shaft are continuously superimposed and accumulated, and the aluminum-containing material will burst due to severe deformation, causing the aluminum foil film material close to the core to be scrapped.

[0023] For this purpose, refer to Figure 1The utility model proposes an aluminum foil reverse-threading and wrinkle-removing transmission device, which includes a frame 100, an unwinding assembly 200, a guide assembly 300 and a rewinding assembly 400. The unwinding assembly 200 is connected to the frame 100 and is used to unwind the aluminum foil film 500. The unwinding assembly 200 includes an unwinding roller 210 and an unwinding reverse-threading member. The unwinding reverse-threading member is adjacent to the unwinding roller 210 and includes three unwinding reverse-threading rollers 220 that are spaced apart and staggered in the upper and lower positions to guide the aluminum foil film 500 to move in an "S" shape. The guide assembly 300 is connected to the frame 100 and is located on the other side of the unwinding reverse-threading member away from the unwinding roller 210. The guide assembly 300 includes a plurality of guide reverse-threading rollers 310, which are spaced apart from each other and staggered in the upper and lower positions to guide the moving direction of the aluminum foil film 500 and guide the aluminum foil film 500 to move in an "S" shape. The winding assembly 400 is connected to the frame 100 and is used to wind up the aluminum foil film material 500. The winding assembly 400 includes a winding roller 410 and a winding reverse threading member. The winding reverse threading member includes three winding reverse threading rollers 420. The three winding reverse threading rollers 420 are arranged alternately at intervals and in upper and lower positions to guide the aluminum foil film material 500 to move in an "S" shape and wind up on the winding roller 410. Furthermore, the guide assembly 300 also includes a pressing roller 320, which abuts against one of the guide reverse threading rollers 310 to press the aluminum foil film material 500.

[0024] Reference Figure 1 It should be noted that the pressing roller 320 is a silicone rubber roller. The pressing roller 320 uses a silicone rubber roller, and the diameter of the silicone rubber pressing roller 320 cannot be less than 140 mm. The wrapping angle between the aluminum foil film material 500 and the pressing roller 320 should be large. Since several guide rollers in the reverse-penetrating pressing roller 320 are reversed by the aluminum foil film material 500, the pressing roller 320 cannot jump when running on the surface of the aluminum foil film material 500. The aluminum foil film material 500 reverses the guide roller on the roller. Under the pull of the winding tension, the guide reverse-penetrating roller 310 is pressed downward by the aluminum foil film, so that the pressing roller 320 will not jump.

[0025] It should be noted that the winding reverse roller 420, the unwinding reverse roller 220 and the guide reverse roller 310 all guide the aluminum foil film material 500 to take an "S"-shaped route, so that one surface of the material contacts and fits with the surface of the guide roller. When the material runs to the next guide roller, the other surface of the material contacts and fits with the surface of the guide roller. The purpose is to allow the surface of the second guide roller to contact the tip of the raised wrinkles with the surface of the guide roller, which plays a role in smoothing the raised wrinkles. The raised wrinkles that appear on the first guide roller are flattened when encountering the second reverse guide roller. This is the role of the aluminum foil film passing through the "S"-shaped winding reverse roller 420, the unwinding reverse roller 220 and the guide reverse roller 310 to smooth the wrinkles. By reversely passing the aluminum foil film material 500 through the guide roller group or the pressure roller 320, the aluminum foil film material 500 is stretched and the raised wrinkles are flattened to ensure product quality.

[0026] In some embodiments, there are multiple guide assemblies 300, and a plurality of transmission rollers 330 are arranged between the multiple guide assemblies 300. The multiple guide assemblies 300 are located between the winding assembly 400 and the unwinding assembly 200, and are arranged at intervals to adapt to the large-area aluminum foil film material 500. After being guided and driven by multiple guide reverse wear rollers 310, the generation of wrinkles is reduced. Furthermore, the guide assembly 300 also includes a steering roller, which abuts against one of the transmission rollers 330 to turn the aluminum foil film material 500 into the next guide assembly 300.

[0027] Reference Figure 1 It should be noted that the unwinding roller 210, the winding roller 410, the unwinding reverse roller 220, the winding reverse roller 420, and the guide reverse roller 310 are all parallel to each other in the horizontal direction. Furthermore, the driving roller 330 is also parallel to the unwinding roller 210, the winding roller 410, the unwinding reverse roller 220, the winding reverse roller 420, the guide roller, and the guide reverse roller 310 in the horizontal direction.

[0028] Reference Figure 1 The rewinding reverse-threading roller 420 located near the rewinding roller 410 abuts against the rewinding roller 410 to press the aluminum foil film 500. A connecting shaft 421 is arranged between the rewinding reverse-threading rollers 420 at both ends in the horizontal direction, and the rewinding reverse-threading roller 420 located in the middle in the horizontal direction is connected to the connecting shaft 421. The arrangement of the connecting shaft 421 can ensure that the guide rollers of the rewinding assembly 400 are parallel to each other to prevent the aluminum foil film 500 from jumping due to tilting, thereby ensuring product quality.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
