Description
Technical Field
[0001] The utility model belongs to the technical field of adhesive film production, and in particular relates to an adhesive film punching and conveying device. Background Art
[0002] Some products are covered with adhesive films to protect them. Such films are usually not covered with glue so that they can be easily removed when the product is used. To accommodate the different shapes and sizes of products, the films need to be punched to obtain films of corresponding shapes and sizes.
[0003] In the process of punching and cutting the film, the film is usually transmitted and wound by a winding roller. However, in the process of transmission, the tension of the film cannot be controlled by relying solely on the winding roller, which will cause the film to be in a relatively loose state during the punching and cutting process. When the film is loose, the punching knife will not be able to quickly and accurately impact and cut the film, which will affect the punching and cutting efficiency and quality of the film.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The utility model provides a film punching and conveying device, which can control the tension of the film. To this end, the basic concept of the technical solution adopted by the utility model is:
[0006] The top end of the support leg is fixedly provided with a toothed plate, and the toothed plate is connected with the toothed plate by the toothed plate, and the toothed plate is connected with the toothed plate at the bottom end thereof of the support leg.
[0007] As a preferred embodiment of the present invention, the punching and conveying mechanism includes an electric telescopic rod fixedly connected to the bottom end of the inner wall of the support frame, the output end of the electric telescopic rod is fixedly connected to the punching knife, the outer wall of the output end of the electric telescopic rod is fixedly connected to a moving rod, the outer wall of the moving rod is fixedly connected to a tooth block, a through groove is opened at the top of the support platform, the inner wall of the through groove is rotatably connected to a conveyor belt, one end of the conveying shaft inside the conveyor belt movably passes through the inner wall of the through groove, one end of the conveying shaft is fixedly connected to a ratchet, the outer wall of the ratchet is squeezed and contacted with a pawl, the outer wall of the pawl away from the ratchet is fixedly connected to a rotating shaft, and the end of the rotating shaft away from the pawl is rotatably connected to the outer wall of the support platform.
[0008] As a preferred embodiment of the present invention, there are two slide bars and two slide blocks respectively, and the slide bars and the slide blocks are distributed on the left and right sides of the top of the support platform in a left-right symmetrical structure.
[0009] As a preferred embodiment of the utility model, the inner wall of the slide groove opened on the top of the support platform fits closely with the outer wall of the sliding block.
[0010] As a preferred embodiment of the present invention, there are several positioning holes, which are evenly and equidistantly distributed on the top of the support platform, and the outer wall of the positioning rod fits snugly with the inner wall of the positioning hole.
[0011] As a preferred embodiment of the present invention, the tooth blocks are made of rubber material, and the tooth blocks are evenly and equidistantly distributed on the outer wall of the moving rod.
[0012] As a preferred embodiment of the utility model, when the punching knife moves downward, the distance that the conveyor belt moves forward is greater than the diameter of the rubber film after punching.
[0013] As a preferred embodiment of the present utility model, the electric telescopic rod and the punching knife are located at the center of the conveyor belt.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The utility model discloses can convey the adhesive film through the conveying roller, connect and fix one end of the adhesive film with the tensioning roller, then carry out the winding and transmission of the adhesive film through the conveying roller and the winding of the tensioning roller. When the tension of the adhesive film needs to be adjusted, the pulling plate is first pulled upward, so that the pulling plate moves upward and drives the positioning rod to move upward. At the same time, the spring will be stretched in the process of the pulling plate moving upward. At this time, the positioning rod will be separated from the positioning effect between the positioning hole, so as to release the positioning effect of the tensioning roller, and then the tensioning roller can be pulled backward. At this time, the tensioning roller will move on the outer wall of the sliding rod through the movement of the slider, so that the adhesive film can be pulled backward, so that the adhesive film can be tightened. After the tensioning position is good, the pulling plate can be released, and the positioning rod can be pushed downward by the rebound effect of the spring until it is inserted into the inner wall of the positioning hole for positioning.
[0016] The utility model starts the electric telescopic rod, and its output end will drive the punching knife to move downward. When the punching knife moves downward and contacts the rubber film, it punches and cuts the rubber film, so that a specified shape can be punched out, and the punched rubber film will fall on the conveyor belt. At the same time, in the process of the output end of the electric telescopic rod moving downward, it will drive the moving rod to move downward. When the moving rod moves downward, it can drive the tooth block arranged on its outer wall to move downward. When the tooth block moves downward, it will mesh with the ratchet wheel so that the ratchet wheel rotates counterclockwise. When the ratchet wheel rotates, it can drive the conveyor belt to rotate, so as to transmit the rubber film fallen thereon. Subsequently, as the moving rod moves upward, the tooth block is driven upward. At this time, the ratchet wheel will be limited by the pawl and will not rotate. Then the tooth block will be squeezed and deformed by the ratchet wheel, so that it can move upward and reset, so as to prepare for the next meshing and rotation transmission.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0026] like Figures 1 to 5 As shown, a film punching and conveying device comprises a support platform 1, a support leg 2 fixedly connected to the bottom end of the support platform 1, a support frame 4 fixedly connected to the top end of the support platform 1, a tensioning adjustment mechanism 31 is arranged at the top end of the support platform 1, a punching and conveying mechanism 32 is arranged above one side of the tensioning adjustment mechanism 31, the tensioning adjustment mechanism 31 comprises a slide bar 311, a slide groove is arranged at the top end of the support platform 1, both ends of the slide bar 311 are fixedly connected to the inner wall of the slide groove, a slide bar 312 is slidably connected to the outer wall of the slide bar 311, and a tensioning roller 313 is fixedly connected to the end of the slide bar 312 away from the bottom end of the inner wall of the slide groove, and the slide bar 312 is positioned at the bottom end of the inner wall of the slide groove. A fixing plate 314 is fixedly connected to one end of one side of the tensioning roller 313, a sliding hole is opened at the top of the fixing plate 314, a positioning rod 315 is slidably connected to the inner wall of the sliding hole, a pulling plate 316 is fixedly connected to the top of the positioning rod 315, a spring 317 is fixedly connected to the end of the pulling plate 316 close to the fixing plate 314, and the end of the spring 317 away from the pulling plate 316 is fixedly connected to the top of the fixing plate 314, a positioning hole 318 is opened at the top of the support platform 1, the outer wall of the positioning rod 315 is clamped on the inner wall of the positioning hole 318, and a conveying roller 319 is fixedly connected to the side of the top of the support platform 1 away from the tensioning roller 313.
[0027] Furthermore, there are two slide bars 311 and two sliders 312, which are symmetrically distributed on the left and right sides of the top of the support platform 1, so that the tensioning roller 313 can be supported on both sides, thereby improving the stability of the tensioning roller 313 during movement.
[0028] Furthermore, the inner wall of the slide groove opened at the top of the support platform 1 fits well with the outer wall of the slider 312, which can further ensure the stability of the tensioning roller 313 during the movement, and at the same time ensure the stability after positioning, without left and right shaking, thereby affecting the accuracy of film punching.
[0029] Furthermore, there are several positioning holes 318, which are evenly and equidistantly distributed on the top of the support platform 1, and the outer wall of the positioning rod 315 fits well with the inner wall of the positioning hole 318. In this way, the tension of the film can be adjusted in multiple gears, thereby improving the applicability of the equipment during use. At the same time, the outer wall of the positioning rod 315 fits well with the inner wall of the positioning hole 318 to ensure stability after positioning.
[0030] The punching and conveying mechanism 32 includes an electric telescopic rod 321 fixedly connected to the bottom end of the inner wall of the support frame 4, the output end of the electric telescopic rod 321 is fixedly connected to a punching knife 322, the outer wall of the output end of the electric telescopic rod 321 is fixedly connected to a moving rod 323, the outer wall of the moving rod 323 is fixedly connected to a tooth block 324, a through slot is provided at the top of the support table 1, the inner wall of the through slot is rotatably connected to a conveyor belt 325, one end of the conveying shaft inside the conveyor belt 325 movably passes through the inner wall of the through slot, one end of the conveying shaft is fixedly connected to a ratchet 326, the outer wall of the ratchet 326 is squeezed and contacted with a pawl 327, the outer wall of the pawl 327 away from the ratchet 326 is fixedly connected to a rotating shaft 328, and the end of the rotating shaft 328 away from the pawl 327 is rotatably connected to the outer wall of the support table 1.
[0031] Furthermore, the tooth block 324 is made of rubber material, and the tooth blocks 324 are evenly and equidistantly distributed on the outer wall of the moving rod 323. The tooth block 324 is made of rubber material so that it can be deformed when resetting, thereby releasing the meshing relationship with the ratchet 326, ensuring that the moving rod 323 can be reset.
[0032] Furthermore, when the punching knife 322 moves downward, the conveyor belt 325 moves forward a distance greater than the diameter of the film after punching. In this way, when the punching knife 322 moves downward, the film punched by the upper wheel can be driven forward to ensure that the film punched this time will not overlap with it.
[0033] Furthermore, the electric telescopic rod 321 and the punching knife 322 are located at the center of the conveyor belt 325, so that the center of the film can be punched, thereby further improving the accuracy of punching.
[0034] The implementation principle of the film punching and conveying device of this embodiment is as follows: the film can be conveyed by the conveying roller 319, one end of the film is connected and fixed to the tensioning roller 313, and then the film is rolled up and transmitted by the conveying roller 319 and the winding of the tensioning roller 313. When the tension of the film needs to be adjusted, the pulling plate 316 is first pulled upward, so that the pulling plate 316 moves upward to drive the positioning rod 315 to move upward. At the same time, the pulling plate 316 will stretch the spring 317 during the upward movement, and the positioning rod 315 will be separated from the positioning hole 318 at this time. The positioning effect of the tensioning roller 313 is released, and the tensioning roller 313 can be pulled backward. At this time, the tensioning roller 313 will move through the movement of the slider 312 on the outer wall of the slide rod 311, so that the film can be pulled backward, so that the film can be tightened. After the position is tightened, the pull plate 316 can be released, and the positioning rod 315 can be pushed downward by the rebound effect of the spring 317 until it is inserted into the inner wall of the positioning hole 318 for positioning. In this way, the film can be kept in a taut state during the punching process, thereby improving the quality and accuracy of the punching of the film.
[0035] By starting the electric telescopic rod 321, its output end will drive the punching knife 322 to move downward. When the punching knife 322 moves downward and contacts the film, it punches the film, so as to punch out a specified shape. The punched film will fall on the conveyor belt 325. At the same time, in the process of the output end of the electric telescopic rod 321 moving downward, it will drive the moving rod 323 to move downward. When the moving rod 323 moves downward, it can drive the tooth block 324 provided on its outer wall to move downward. When the tooth block 324 moves downward, it will contact with the tooth block 324. The ratchet 326 is engaged so that the ratchet 326 rotates counterclockwise. When the ratchet 326 rotates, the conveyor belt 325 can be driven to rotate, thereby transmitting the film falling thereon. Then, as the moving rod 323 moves upward, the tooth block 324 is driven to move upward. At this time, the ratchet 326 will be limited by the pawl 327 and will not rotate. Then the tooth block 324 will be squeezed and deformed by the ratchet 326, so that it can move upward and reset, preparing for the next engagement and rotation transmission.
