Description
Technical Field
[0001] This utility model relates to a film slitting machine, specifically, to a film slitting machine with automatic deviation correction function. Background Technology
[0002] A film is a thin, flexible, transparent sheet, ranging in thickness from a single atom to several millimeters, consisting of a thin layer of metal or organic material. It is primarily made of plastics, adhesives, rubber, or other materials. Films are widely used in the electronics, machinery, and printing industries. Because the produced films are typically wide, a film slitting machine cuts them into several narrower films. The film slitting process involves unwinding, moving, slitting, and rewinding. The rewinding roller pulls the film, and the film is slit during this pulling process. During this process, the film is subjected to different... Under the influence of directional and forceful forces, as well as the action of the film slitting machine, the film is prone to deviation during movement. Existing film slitting machines typically have two baffles installed on the moving rollers, and the film moves between the two baffles. The two baffles restrict the movement path of the film to reduce the probability of deviation. However, during the movement, the edges of the film slide and rub against the sidewalls of the baffles, which can easily cause damage to the edges of the film, resulting in increased film waste. In view of this, we propose a film slitting machine with an automatic deviation correction function. Utility Model Content
[0003] The purpose of this invention is to provide a film slitting machine with automatic correction function to solve the problem mentioned in the background art of film edge friction with baffle causing film damage and increased film waste.
[0004] To address the aforementioned problems, the present invention aims to provide a film slitting machine with automatic deviation correction function, comprising a slitting machine body. An unwinding roller, a winding roller, and two guide rollers are rotatably connected inside the slitting machine body. The unwinding roller unwinds the rolled film, the two guide rollers change the film's movement path, and the winding roller winds the slit film. The slitting machine body is internally equipped with a limiting mechanism and an adjusting mechanism. The limiting mechanism restricts the film's movement path, and the adjusting mechanism adjusts any deviations in the film's movement path. The limiting mechanism includes two transmission components, with a supporting rotating rod rotatably connected between them. A supporting rotating roller is coaxially fixedly connected to the supporting rotating rod. A limiting rotating rod is rotatably connected inside the transmission components, and a limiting rotating roller is coaxially fixedly connected to the limiting rotating rod. The transmission components connect the supporting rotating rod and the limiting rotating rod together, and the supporting rotating rod drives the limiting rotating rod to rotate synchronously through the transmission components during rotation.
[0005] As a further improvement to this technical solution, the transmission assembly includes a mounting frame, the supporting rotating rod is rotatably connected between two mounting frames via bearings, the limiting rotating rod is rotatably connected inside the mounting frame via bearings, and the limiting rotating rod is perpendicular to the supporting rotating rod.
[0006] As a further improvement to this technical solution, the diameters of the cross sections of the supporting roller and the limiting roller are the same. The synchronously rotating supporting rod and the limiting rod drive the supporting roller and the limiting roller to rotate synchronously, and the film is located between the two limiting rollers during the movement.
[0007] As a further improvement to this technical solution, a mounting rod is fixedly connected to the side of the mounting frame away from the supporting rotating rod. The end of the mounting rod away from the mounting frame is fixedly connected to the inner wall of the slitting machine body near the top, and the mounting frame is connected to the slitting machine body through the mounting rod.
[0008] As a further improvement to this technical solution, a reduction motor is fixedly connected to the lower side of one of the mounting rods. The output shaft of the reduction motor passes through the mounting frame and is coaxially connected to one end of the support rotating rod through a coupling. The output shaft of the reduction motor drives the support rotating rod and the support rotating roller to rotate.
[0009] As a further improvement to this technical solution, two transmission bevel gears are coaxially fixedly connected to the support rotating rod near both ends. A driven bevel gear is coaxially fixedly connected to the end of the limiting rotating rod near the transmission bevel gear. The driven bevel gear meshes with the transmission bevel gear. The rotating support rotating rod drives the transmission bevel gear to rotate, which in turn drives the driven bevel gear, the limiting rotating rod, and the limiting rotating roller to rotate.
[0010] As a further improvement to this technical solution, the adjustment mechanism includes a moving component, and a lifting frame is fixedly connected to the upper side of the moving component. Two adjusting rollers are rotatably connected to the top of the lifting frame near both sides via bearings. The moving component drives the lifting frame and the adjusting rollers to move vertically and horizontally.
[0011] As a further improvement to this technical solution, the moving component includes two fixed rods fixedly connected inside the slitting machine body. A moving plate is slidably connected to the two fixed rods. Two first electric telescopic rods are fixedly connected to the upper side of the moving plate near both ends. The piston rods of the two first electric telescopic rods are fixedly connected to the lower side of the lifting frame. During the extension and retraction process, the piston rods of the first electric telescopic rods drive the lifting frame to move upward or downward. A second electric telescopic rod is fixedly connected to one side of the slitting machine body. The piston rod of the second electric telescopic rod passes through the side wall of the slitting machine body and is fixedly connected to one side of the moving plate. During the extension and retraction process, the piston rod of the second electric telescopic rod drives the moving plate to move horizontally along the axis of the fixed rods.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This film slitting machine with automatic correction function, during the film movement process, the support rod and support roller rotate to drive the film movement. The rotating support rod drives the limiting rod and limiting roller to rotate synchronously through the transmission component. Under the restriction of the two limiting rollers, the movement path of the film is restricted, reducing the probability of film deviation. At the same time, the side walls of the two limiting rollers roll into contact with the edge of the film, shortening the distance of friction between the edge of the film and the limiting roller during the movement process, thereby reducing the wear on the edge of the film and reducing film waste.

[0025] 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.
[0026] Example 1
[0027] Please see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a film slitting machine with automatic correction function, including a slitting machine body 1. The slitting machine body 1 is rotatably connected to an unwinding roller 11, a winding roller 12, and two guide rollers 13. The unwinding roller 11 unwinds the rolled film, and the two guide rollers 13 change the movement path of the film. One end of the winding roller 12 is coaxially connected to a motor fixed on the film slitting machine through a coupling. The output shaft of the rotating motor drives the winding roller 12 to rotate. The rotating winding roller 12 winds up the slitting film. The slitting machine body 1 is provided with a limiting mechanism 2 and an adjusting mechanism 3. The limiting mechanism 2 restricts the movement path of the film, and the adjusting mechanism 3 adjusts the film whose movement path has deviated. Several slitting blades are fixedly connected inside the slitting machine body 1. The film is slitting during the film movement process.
[0028] In the initial state, the adjusting mechanism 3 is located below the limiting mechanism 2. The operator coaxially fixes the roll of film to be cut onto the unwinding roller 11. Then, the operator pulls one end of the film to move it through the two guide rollers 13 and the limiting mechanism 2. The operator wraps the other end of the film around the take-up roller 12 and cuts the moving film with a slitting knife. Under the restriction of the limiting mechanism 2, the probability of the film deviating during movement is reduced. When the film's movement path deviates, the adjusting mechanism 3 drives the film to move upward to separate it from the limiting mechanism 2. Then, the adjusting mechanism 3 drives the film to move horizontally, adjusting the film's movement path so that the film that has deviated from the path returns to its original movement path, avoiding uneven film width after cutting, thereby improving the film cutting effect.
[0029] refer to Figure 3 - Figure 5The limiting mechanism 2 includes two transmission components, with a support rotating rod 23 rotatably connected between the two transmission components. A support rotating roller 24 is coaxially fixedly connected to the support rotating rod 23. The film moves along the upper side of the support rotating roller 24. The transmission components include a mounting frame 22. The support rotating rod 23 is rotatably connected between the two mounting frames 22 via bearings. A limiting rotating rod 25 is rotatably connected inside the mounting frame 22 via bearings. The limiting rotating rod 25 is perpendicular to the support rotating rod 23. A mounting rod 21 is fixedly connected to the side of the mounting frame 22 away from the support rotating rod 23. The end of the mounting rod 21 away from the mounting frame 22 is fixedly connected to the inner wall of the slitting machine body 1 near the top. The mounting frame 22 is connected to the slitting machine body 1 via the mounting rod 21 to install the support rotating roller 24 inside the slitting machine body 1, so that the support rotating roller 24 remains stable during the film movement.
[0030] A geared motor 29 is fixedly connected to the lower side of one of the mounting rods 21. The output shaft of the geared motor 29 passes through the mounting frame 22 and is coaxially connected to one end of the support rotating rod 23 through a coupling. The output shaft of the geared motor 29 rotates, driving the support rotating rod 23 and the support rotating roller 24 to rotate. The support rotating roller 24 drives the film to move during the rotation.
[0031] The transmission assembly includes an internally rotating limit rod 25, on which a limit roller 26 is coaxially fixed. The transmission assembly connects the support rod 23 and the limit rod 25. During rotation, the support rod 23 drives the limit rod 25 to rotate synchronously via the transmission assembly. Two transmission bevel gears 28 are coaxially fixedly connected near both ends of the support rod 23. A driven bevel gear 27 is coaxially fixedly connected to one end of the limit rod 25 near the transmission bevel gears 28. The driven bevel gear 27 meshes with the transmission bevel gear 28. The rotating support rod 23 drives... The transmission bevel gear 28 rotates, causing it to drive the driven bevel gear 27, the limiting rotating rod 25, and the limiting rotating roller 26 to rotate. The support rotating roller 24 and the limiting rotating roller 26 have the same cross-sectional diameter. The synchronously rotating support rotating rod 23 and the limiting rotating rod 25 drive the support rotating roller 24 and the limiting rotating roller 26 to rotate synchronously, respectively. During the movement, the film is located between the two limiting rotating rollers 26. At the same time, the edges of the moving film make rolling contact with the two limiting rotating rollers 26, shortening the distance between the film edge and the limiting rotating roller 26, reducing the wear on the film edge, and reducing film waste.
[0032] refer to Figure 6 and Figure 7The adjustment mechanism 3 includes a moving component. A lifting frame 31 is fixedly connected to the upper side of the moving component. Two adjusting rollers 32 are rotatably connected to the top of the lifting frame 31 near both sides via bearings. The moving component drives the lifting frame 31 and the adjusting rollers 32 to move vertically and horizontally. When the film's movement path deviates, the moving component drives the lifting frame 31 and the adjusting rollers 32 to move towards the limiting mechanism 2. The moving adjusting rollers 32 contact the film and drive the film to move, causing the film to separate from the limiting mechanism 2. At this time, the moving component drives the lifting frame 31 and the adjusting rollers 32 to move horizontally. The moving lifting frame 31 and the adjusting rollers 32 drive the film to move, thereby adjusting the film's movement path, restoring the deviated film to its original movement path, and improving the film slitting effect of the film slitting machine.
[0033] The movable component includes two fixed rods 33 fixedly connected inside the slitting machine body 1. A movable plate 34 is slidably connected to the two fixed rods 33. Two first electric telescopic rods 35 are fixedly connected to the upper side of the movable plate 34 near both ends. The piston rods of the two first electric telescopic rods 35 are fixedly connected to the lower side of the lifting frame 31. During the extension and retraction process, the piston rods of the first electric telescopic rods 35 drive the lifting frame 31 to move up or down. A second electric telescopic rod 36 is fixedly connected to one side of the slitting machine body 1. The piston rod of the second electric telescopic rod 36 passes through the side wall of the slitting machine body 1 and is fixedly connected to one side of the movable plate 34. During the extension and retraction process, the piston rod of the second electric telescopic rod 36 drives the movable plate 34 to move horizontally along the axis of the fixed rods 33.
[0034] When using this device:
[0035] In the initial state, the adjustment mechanism 3 is located below the limiting mechanism 2. The operator coaxially fixes the roll of film to be cut onto the unwinding roller 11. Then, the operator pulls one end of the film to pass through the two guide rollers 13 and the support roller 24 and wraps the end of the film around the winding roller 12. The output shaft of the motor rotates and drives the winding roller 12 to rotate so that it can wind up and pull the film. During the winding process, the film is cut by a slitting knife.
[0036] During the film winding process, the output shaft of the geared motor 29 rotates, driving the support rod 23 and the support roller 24 to rotate. The rotating support rod 23 drives the limiting rod 25 and the limiting roller 26 to rotate through the transmission bevel gear 28 and the driven bevel gear 27. Under the restriction of the limiting roller 26, the probability of the film movement path deviating is reduced.
[0037] When the film shifts, the piston rod of the first electric telescopic rod 35 extends, driving the lifting frame 31 and the adjusting roller 32 to move upward. The moving adjusting roller 32 lifts the film, separating it from the supporting rotating roller 24. At this time, the piston rod of the second electric telescopic rod 36 extends or retracts, driving the moving plate 34 to move horizontally, thus adjusting the movement path of the film.
