Description

Technical Field

[0001] This application relates to the field of film winding, and particularly to a winding mechanism for PET films. Background Art

[0002] The winding mechanism for PET films is mainly used to wind the produced PET films into rolls according to predetermined specifications and quality requirements, so as to facilitate subsequent storage, transportation, and processing and use. By controlling the tension and winding speed, the flatness and tightness of the wound film are ensured to meet the needs of different industries, such as food packaging, medical use, and industrial applications, etc.

[0003] For example, a film winding mechanism with the publication number 202321914208.5 includes a base, a fixed seat, and a mounting seat. A fixed seat is provided on the surface of the base, a mounting seat is provided on one side of the fixed seat, a movable seat is provided on the side of the base away from the fixed seat, a winding roller is connected between the movable seat and the fixed seat through the mounting seat, and a stabilizing rod is provided on the surface of the base near the fixed seat and the movable seat. There are still the following deficiencies in actual use:

[0004] When the above-mentioned film winding mechanism is actually used, the air bubbles between the films are scraped off by a scraping plate. Since the film itself is extremely easy to break, the surface of the film is easily damaged when the scraping plate slides, resulting in the film being unusable. And when winding to the maximum extent, it is necessary to manually observe when to cut. Due to the large error in the manual grasp of the size, the thickness of each roll of film is inconsistent, resulting in the phenomenon of inconsistent specifications. Utility Model Content

[0005] In order to improve the problem of film breakage caused when removing air bubbles between films, this application provides a winding mechanism for PET films.

[0006] The winding mechanism for PET films provided by this application adopts the following technical solutions:

[0007] A winding mechanism for PET films includes a device bottom plate. A support member is fixedly connected to the top of the device bottom plate, a support plate is fixedly connected to the top of the device bottom plate, and an anti-bubble automatic disconnection mechanism is provided on the top of the device bottom plate;

[0008] The anti-bubble automatic disconnection mechanism includes a motor fixedly connected to the top of the support member. The output shaft end of the motor movably penetrates the side wall of the support plate and extends to the outside, and a winding cylinder is fixedly connected to the end. The anti-bubble automatic disconnection mechanism further includes a vertical plate. A rotating shaft movably penetrates the side wall of the vertical plate, and a roller is fixedly connected to the end of the rotating shaft that movably penetrates the side wall of the vertical plate and extends to the outside.

[0009] By adopting the above technical solution, the rotation and pressing of the roller are used to ensure that there are no gaps between the films during the winding process.

[0010] Preferably, a horizontal plate is fixedly connected to the top of the support plate.

[0011] By adopting the above technical solution, the support plate vertically fixes the horizontal plate, thereby improving the stability of the structure.

[0012] Preferably, the vertical plate movably penetrates through the top of the horizontal plate.

[0013] By adopting the above technical solution, the horizontal plate limits the vertical plate.

[0014] Preferably, a horizontal block is fixedly connected to the top of the vertical plate, and a spring fixedly connected to the top of the horizontal plate is fixedly connected to the bottom of the horizontal block.

[0015] By adopting the above technical solution, when the horizontal block moves vertically, the spring will be stretched.

[0016] Preferably, a connecting plate is fixedly connected to the side wall of the vertical plate, a screw threadedly penetrates through the top of the connecting plate, and a connecting block is fixedly connected to the side wall of the horizontal plate.

[0017] By adopting the above technical solution, the vertical height of the screw can be adjusted by rotation.

[0018] Preferably, a fixing plate is fixedly connected to the bottom of the connecting block, a fixing shaft movably penetrates through the side wall of the fixing plate, and a rotating bar is fixedly penetrated through the middle of the fixing shaft.

[0019] By adopting the above technical solution, the rotation of the fixing shaft can drive the rotating bar to rotate.

[0020] Preferably, a rotating plate is fixedly connected to one end of the rotating bar away from the horizontal plate, a blade is fixedly connected to the bottom of the rotating plate, and a jacking plate is fixedly connected to the end of the rotating bar away from the rotating plate.

[0021] By adopting the above technical solution, when the rotating plate moves, the blade can be driven to move.

[0022] Preferably, a connecting column is fixedly connected to the top of the connecting block, and a tension rope with the other end fixedly connected to the top of the rotating plate is fixedly connected to the side wall of the connecting column.

[0023] By adopting the above technical solution, when the rotating plate rotates, the tension rope will be pulled to stretch.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By continuously winding the film on the outer wall of the winding drum, the diameter of the winding drum will gradually increase, causing the roller to move vertically upward. At this time, the horizontal block will move vertically synchronously, and the spring will be stretched. Due to the elasticity of the spring, the roller will apply a vertically downward force to the winding drum, thus preventing gaps from appearing between the films during the winding process and avoiding the generation of bubbles. When the winding drum rotates, the roller rotates synchronously while adhering to the outer wall of the winding drum, thus preventing damage to the film.

[0026] 2. As more and more film is wound on the winding drum, the diameter of the winding drum gradually increases, and the screw will move vertically upward with the vertical plate. The screw will push up the lifting plate. When the blade is lifted, the lifting plate will drive the rotating bar to rotate, causing the rotating plate to rotate counterclockwise downward. The rotating plate will drive the blade to cut the film, thus stopping the winding of the winding drum, ensuring that each wound film has the same diameter, avoiding the phenomenon of insufficient quantity, and making the product batch specifications consistent.

[0034] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.

[0035] The embodiment of the present application discloses a winding mechanism for a PET film.

[0036] Embodiment 1

[0037] Refer toFigure 1 , a winding mechanism for a PET film includes a device base plate 1. The top of the device base plate 1 is fixedly connected to the bottom of a support member 11, thereby providing vertical support for a motor 21. The top of the device base plate 1 is fixedly connected to the bottom of a support plate 12. An anti-bubble automatic disconnection mechanism 2 is provided on the top of the device base plate 1.

[0038] Through the above settings, the staff places the device base plate 1 stably.

[0039] Refer to Figure 2 , as shown in FIG. 3, the anti-bubble automatic disconnection mechanism 2 includes a vertical plate 24. A circular hole one is opened on the side wall of the vertical plate 24. A rotating shaft 29 movably penetrates through the circular hole one opened on the side wall of the vertical plate 24, so that the rotating shaft 29 is rotatably connected to the vertical plate 24. One end of the rotating shaft 29 that movably penetrates through the side wall of the vertical plate 24 and extends to the outside is fixedly connected to one end of a roller 210 close to the rotating shaft 29. The anti-bubble automatic disconnection mechanism 2 further includes a motor 21 fixedly connected to the top of the support member 11. One end of the output shaft of the motor 21 that movably penetrates through the side wall of the support plate 12 and extends to the outside is fixedly connected to one end of a winding cylinder 22 close to the motor 21. The top of the support plate 12 is fixedly connected to the bottom of a cross plate 23. A square hole one is penetrated through the top of the cross plate 23. The vertical plate 24 movably penetrates through the square hole one, so that the vertical plate 24 is slidably connected to the cross plate 23. The top of the vertical plate 24 is fixedly connected to the bottom of a horizontal block 25, so that the horizontal block 25 can drive the vertical plate 24 to perform vertical movement. The bottom of the horizontal block 25 is fixedly connected to the top of a spring 26. The bottom of the spring 26 is fixedly connected to the top of the cross plate 23. The side wall of the vertical plate 24 is fixedly connected to the side wall of a connecting plate 27. A threaded hole one is opened through the top of the connecting plate 27. A screw 28 threadedly penetrates through the threaded hole one, so that the screw 28 is threadedly connected to the connecting plate 27.

[0040] The staff aligns and adheres one end of the film parallel to the surface of the winding cylinder 22. Subsequently, the staff starts the motor 21. The motor 21 will drive the winding cylinder 22 to rotate. The winding cylinder 22 will continuously wind the film, so that the thickness of the film on the outer wall of the winding cylinder 22 becomes thicker and thicker. The bottom of the roller 210 is in contact with the surface of the winding cylinder 22. When the winding cylinder 22 rotates, it will drive the roller 210 to rotate continuously through mutual friction. When the thickness of the film on the surface of the winding cylinder 22 gradually increases, the roller 210 will gradually rise under the influence of the film thickness. Subsequently, the roller 210 will drive the vertical plate 24 to rise vertically. The vertical plate 24 will drive the horizontal block 25 to move vertically upward. The horizontal block 25 will pull the spring 26 to elongate. The spring 26 will exert a downward pulling force on the horizontal block 25. The horizontal block 25 will transmit the pulling force to the roller 210 through the vertical plate 24, so that the roller 210 exerts a downward pressure, thereby squeezing the outermost layer of the film on the winding cylinder 22, so as to ensure that no bubbles will appear between the films during the winding process and improve the winding quality.

[0041] Reference Figure 2 , 3. The side wall of the cross plate 23 is fixedly connected to the side of the connecting block 211 close to the cross plate 23. The bottom of the connecting block 211 is fixedly connected to the top of the fixing plate 212. A through circular hole two is opened on the side wall of the fixing plate 212. The fixing shaft 213 movably penetrates through the circular hole two, so that the fixing shaft 213 is rotatably connected to the fixing plate 212. A circular hole three is penetrated through the middle side wall of the rotating bar 214. The fixing shaft 213 fixedly penetrates through the circular hole three in the middle of the rotating bar 214, so that the fixing shaft 213 is fixedly connected to the rotating bar 214. The end of the rotating bar 214 away from the cross plate 23 is fixedly connected to the side of the rotating plate 215 close to the rotating bar 214, so that the rotating bar 214 can drive the rotating plate 215 to rotate. The bottom of the rotating plate 215 is fixedly connected to the top of the blade 216, so that the rotating plate 215 drives the blade 216 to move synchronously. The end of the rotating bar 214 away from the rotating plate 215 is fixedly connected to the side of the lifting plate 217 close to the rotating bar 214, so that the lifting plate 217 can drive the rotating bar 214 to rotate. The top of the connecting block 211 is fixedly connected to the bottom of the connecting column 218. The side wall of the connecting column 218 is fixedly connected to one end of the tension rope 219 close to the connecting column 218. The other end of the tension rope 219 is connected to the top of the rotating plate 215. The tension rope 219 is made of nylon material and has a certain elasticity, so as to reset the rotated blade 216.

[0042] When the thickness on the surface of the winding drum 22 reaches the specified thickness of a roll of film, at this time, the vertical plate 24 moves upward through the lifting of the thickness. The vertical plate 24 will drive the connecting plate 27 to move vertically upward. The connecting plate 27 will drive the screw 28 to move vertically upward. The screw 28 will lift the lifting plate 217. When the lifting plate 217 is lifted upward, the lifting plate 217 will drive the rotating bar 214 to rotate. The rotating bar 214 will drive the rotating plate 215 to rotate. The rotating plate 215 will drive the blade 216 to rotate, so that the blade 216 rotates downward counterclockwise, so as to cut off the film, and thus complete the winding work of a roll of film. When a roll of film is removed, the vertical plate 24 will fall back to its original position. At this time, the lifting plate 217 is not lifted, and the tension rope 219 will pull the blade 216 back to its original position.

[0043] Among them, the motor 21 is a prior art, and its structural principle will not be described in detail.

[0044] The implementation principle of the winding mechanism of a PET film in the embodiment of the present application is as follows:

[0045] Pull the horizontal block 25 downward through the spring 26, so that the roller 210 applies a downward pressure, ensuring that no bubbles appear during the process of winding the film on the winding drum 22. When bubbles appear between the films during the winding process, when the thickness standard of a roll of film is reached, the screw 28 will jack up the jacking plate 217, so that the jacking plate 217 drives the rotating plate 215 to rotate, driving the blade 216 to cut off the film, ensuring that the thickness of each roll of film is consistent.

[0046] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
