Abstract
Description
Technical Field
[0001] This utility model relates to the field of film slitting technology, specifically a large roll film slitting and winding mechanism. Background Technology
[0002] Film slitting and rewinding processes cut wider rolls of film into narrower strips and rewind them to create sizes and specifications suitable for different applications, making it convenient for users.
[0003] In related technologies, a search revealed a scheme for a rewinding mechanism after film slitting (announcement number CN220596458U), which uses the pressure generated between the pressure roller and the winding roller to squeeze out any air bubbles that may be generated, effectively reducing the generation of air bubbles between film layers, and uses a dust removal mechanism to blow away dust particles, effectively reducing the adhesion of dust particles.
[0004] However, manually removing film rolls is suitable for lighter ones. Heavier film rolls are difficult to remove manually, cause severe wear and tear on the paper tube, and are not very efficient. Utility Model Content
[0005] The purpose of this invention is to provide a large roll film slitting and winding mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a large roll film slitting and winding mechanism, including a slitting and rewinding machine, wherein an air shaft and a pusher located on the left side of the air shaft are installed on the slitting and rewinding machine, and the pusher can push the film roll off the air shaft;
[0007] The slitting and rewinding machine is equipped with a first cylinder at the bottom and a V-shaped plate at the top. A conveyor is installed in the V-shaped plate. The conveyor transports the film roll on the air shaft down, realizing the automatic removal of the film roll and reducing manual labor.
[0008] A support base is provided, on which a receiving plate is movably mounted. The receiving plate receives the film roll fed down from the air expansion shaft and can automatically transport the film roll.
[0009] Furthermore, the pusher includes a bracket and a second cylinder mounted on the bracket. The second cylinder pushes the film roll on the surface of the air expansion shaft to slide onto the receiving plate. A push plate is installed at the right end of the second cylinder. The push plate is crescent-shaped and can assist in pushing some heavier film rolls, thereby improving the unloading stability of large film rolls.
[0010] Furthermore, the conveyor includes a wheel frame and a drive roller mounted on the wheel frame. A conveyor belt is mounted on the drive roller. Two inclined conveyor belts support and transport the film roll, realizing automatic transport of the film roll and reducing the risk of damaging the paper tube.
[0011] Furthermore, the surface of the receiving plate is equipped with several rollers, which makes it less prone to wear on the film roll and makes the movement of the film roll smoother.
[0012] Furthermore, a hinge seat and a third cylinder are rotatably installed between the support base and the receiving plate. The third cylinder pushes the receiving plate to tilt, which can roll the film roll to other positions.
[0013] Compared with the prior art, the beneficial effects of this utility model are: after the air shaft is deflated, it no longer clamps the film roll; the first cylinder pushes the V-shaped plate so that the two conveyor belts support the film roll, the film roll separates from the air shaft; the rotation of the conveyor belt, in conjunction with the push of the second cylinder, causes the film roll to move towards the receiving plate, thereby realizing the automatic removal of the air shaft, reducing the physical burden on workers and improving the automation level of film roll production.

[0018] 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.
[0019] Example:
[0020] Please see Figure 1-3 This utility model provides a technical solution: a large roll film slitting and winding mechanism, including a slitting and rewinding machine 1, wherein an air shaft 5 and a pusher located on the left side of the air shaft 5 are installed on the slitting and rewinding machine 1, a paper tube is sleeved on the air shaft 5, and the slitting and rewinding machine 1 cuts the large roll film into small-sized films and winds them into film rolls using paper tubes.
[0021] The slitting and rewinding machine 1 is equipped with a first cylinder 7 at the lower part and a V-shaped plate 8 at the upper end of the first cylinder 7. A conveyor is installed in the V-shaped plate 8. The conveyor transports the film roll on the air expansion shaft 5 down. The first cylinder 7 causes the conveyor to support the film roll, and the paper tube separates from the air expansion shaft 5. At this time, the movement of the film roll can prevent the paper tube from being worn.
[0022] Support base 9, on which a receiving plate 13 is movably installed. The receiving plate 13 receives the film roll sent down from the air expansion shaft 5. The receiving plate 13 can loosely distribute a portion of the film roll.
[0023] In this embodiment, if Figure 1 As shown, a support plate 6 is installed at the lower part of the slitting and rewinding machine 1. The first cylinder 7 is installed on the surface of the support plate 6. Multiple first cylinders 7 can be installed on the support plate 6, so that the V-shaped plate 8 can support the film roll more stably.
[0024] In this embodiment, if Figure 1 As shown, the pusher includes a bracket 2 and a second cylinder 3 mounted on the bracket 2. The second cylinder 3 pushes the film roll on the surface of the air expansion shaft 5 onto the receiving plate 13. A push plate 4 is installed at the right end of the second cylinder 3. The push plate 4 is crescent-shaped and has a large contact area with the film roll, resulting in a stronger pushing force on the film roll. Together with the conveyor belt 15, it more stably pushes the film roll away from the air expansion shaft 5.
[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the conveyor includes a wheel frame 17 and a drive roller 14 mounted on the wheel frame 17. A conveyor belt 15 is mounted on the drive roller 14. The drive roller 14 is provided with multiple supports to the conveyor belt 15 to increase the support of the conveyor belt 15 on the film roll.
[0026] In this embodiment, if Figure 3 As shown, a plurality of rollers 16 are mounted on the surface of the receiving plate 13. The film roll moves along the rollers 16 with little resistance, thus avoiding wear on the film roll.
[0027] In this embodiment, if Figure 1 As shown, a hinge seat 11 and a third cylinder 12 are rotatably installed between the support base 9 and the receiving plate 13. The third cylinder 12 pushes the receiving plate 13, which can tilt the receiving plate 13, thereby allowing the film roll on the receiving plate 13 to roll down.
[0028] In this embodiment, if Figure 1 As shown, an auxiliary seat 10 is fixedly connected to the surface of the support seat 9. The auxiliary seat 10 supports the receiving plate 13, thus preventing the third cylinder 12 from supporting the receiving plate 13 alone.
[0029] Specifically, in use, the large roll of film is placed on the slitting and rewinding machine 1, and the paper tube is placed on the air shaft 5. The air shaft 5 is inflated and holds the paper tube in place. After the large roll of film is slit, it is wound onto the paper tube to form a film roll. When it is necessary to remove the film roll from the air shaft 5, the air shaft 5 is deflated and no longer holds the paper tube. The first cylinder 7 pushes up the V-shaped plate 8. The two conveyor belts 15 in the V-shaped plate 8 support the film roll so that the paper tube is no longer in contact with the air shaft 5. The drive roller 14 drives the conveyor belt 15 to rotate. The conveyor belt 15 transports the film roll towards the roller 16. The rotation of the roller 16 reduces the resistance to the movement of the film roll. Then, the third cylinder 12 pushes up the receiving plate 13. When the receiving plate 13 is tilted, the film roll rolls off the roller 16, making room for the next batch of film rolls, thus realizing the automatic separation of the film roll from the air shaft 5.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
