Technical Field

[0001] This utility model relates to the field of film conveying technology, and in particular to a deviation correction device for film production and conveying. Background Technology

[0002] The film correction machine is a correction device used for hot air hot-cut bag making machines and printing machine roll materials. The film correction machine transmits the signal to the correction controller according to the photoelectric sensor, and then the controller outputs the correction signal to the stepper motor of the film correction machine. The stepper motor drives the roller on the machine to move according to the received control signal, so as to achieve the correction effect of the output film. A search of existing Chinese patent technology reveals an "Automatic Deviation Correction Device for Casting Machine in PVA Film Production" with publication number "CN215363229U". This device uses a sliding bearing seat to drive a redirecting roller to move, causing the conveyor belt's conveying angle to shift inward until the conveyor belt disengages from the roller, thus achieving automatic deviation correction. However, during film conveying, this device may cause wrinkles in the film, which can lead to deviations in film conveying and affect the finished product quality of the film after conveying. Utility Model Content

[0003] Therefore, it is necessary to provide a film production and conveying correction device to address the problem that wrinkles may form on the film during the film conveying process, causing the film to deviate and affecting the finished product quality.

[0004] A film production conveying correction device is provided, comprising: a base, with two rollers fixedly connected to the upper end of the base; and an anti-deviation mechanism disposed between the two rollers and installed on the upper end of the base. The anti-deviation mechanism includes a frame fixedly connected to the upper end of the base, the frame being disposed between the two rollers. Multiple rotating columns are rotatably connected to the inner wall of the frame. A flattening and correction component is disposed inside the frame, one end of which extends through to one side of the frame. Two side-limiting components are disposed at the lower end of the flattening and correction component, the ends of which extend through to the outside of the frame.

[0005] In one embodiment, the flattening and straightening assembly includes a rotating shaft rotatably connected to the inner wall of the frame. Two rubber sheets are fixedly connected to the surface of the rotating shaft. The rubber sheets are spiral in shape and the spiral directions of the two rubber sheets are opposite. The end of the rotating shaft extends to the outside of the frame, and the ends of the two rubber sheets are fixedly connected to each other.

[0006] In one embodiment, the side limiting assembly includes a round rod fixedly connected to the inner wall of the frame, a limiting frame is provided on the side of the round rod near the adjacent roller, and two connecting seats are fixedly connected on the side of the limiting frame away from the roller.

[0007] In one embodiment, a sleeve is fixedly connected to the inner wall of the connecting seat, and the lower end of the sleeve is slidably connected to the surface of the round rod.

[0008] In one embodiment, the flattening and straightening assembly includes a connecting column fixedly connected to the end of the adjacent rotating column, and pulleys are fixedly connected to the surface of the rotating shaft and the surface of the connecting column.

[0009] In one embodiment, a drive belt is fitted onto the surfaces of the two pulleys, and the inner edge of the drive belt is connected to the inner wall of the pulleys in a driving connection.

[0010] In one embodiment, the inner wall of the upper sleeve is provided with a threaded shaft, the end of which is rotatably connected to the inner wall of the frame.

[0011] In one embodiment, the surface of the threaded shaft is threaded to the inner wall of the adjacent sleeve, and the end of the threaded shaft extends to the outside of the frame and is fixedly connected to an operating handle.

[0012] Beneficial effects 1. The above-mentioned film production and conveying correction device, through the rotation of the rotating column in contact with the film, will drive the connecting column to rotate synchronously. Since the rubber sheet is made of flexible rubber, when the rubber sheet contacts the film, the outer edge of the rubber sheet contacts the film. At this time, the rubber sheet will move the film, reduce the wrinkles of the film during the conveying process, ensure the stability of the film conveying, reduce the deviation of the film conveying, and ensure the finished product effect of the film after conveying. 2. The two limiting frames can limit the two sides of the film. The screw shaft can be rotated synchronously by the knob operation handle. Under the guidance of the lower sleeve and the round rod, the limiting frame and the film are kept in the same direction, which forms a good limit during the film transportation process. This allows for a good correction effect when the film deviates during the film transportation process. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The following is combined Figures 1-5 This invention describes a correction device for film production and conveying.

[0018] In one embodiment, a film production conveying correction device includes: a base 1, with two rollers 2 fixedly connected to the upper end of the base 1; and an anti-deviation mechanism 3, which is disposed between the two rollers 2 and installed on the upper end of the base 1. The anti-deviation mechanism 3 includes a frame 31 fixedly connected to the upper end of the base 1, which is disposed between the two rollers 2. A plurality of rotating columns 311 are rotatably connected to the inner wall of the frame 31. A flattening correction component 32 is disposed inside the frame 31. One end of the flattening correction component 32 extends through to one side of the frame 31, and two side limiting components 33 are disposed at the lower end of the flattening correction component 32. The ends of the side limiting components 33 extend through to the outside of the frame 31. It should be noted that the film can pass through the frame 31 through the roller 2 and be wound around the surface of the rotating column 311 in the frame 31. The film will then contact the surface of the flattening and correction component 32 at its highest point. The flattening and correction component 32 can correct the film's deviation in the middle of the film conveying process, thus maintaining the smoothness of the film conveying. like Figure 1-4As shown, the flattening and straightening assembly 32 includes a rotating shaft 321 rotatably connected to the inner wall of the frame 31. Two rubber sheets 322 are fixedly connected to the surface of the rotating shaft 321. The rubber sheets 322 are spiral in shape and the spiral directions of the two rubber sheets 322 are opposite. The end of the rotating shaft 321 extends to the outside of the frame 31, and the ends of the two rubber sheets 322 are fixedly connected to each other. The flattening and straightening assembly 32 also includes a connecting column 323 fixedly connected to the end of the adjacent rotating column 311. Both the surface of the rotating shaft 321 and the surface of the connecting column 323 are fixedly connected to pulleys 324. The surfaces of the two pulleys 324 are fitted with a transmission belt 325, and the inner edge of the transmission belt 325 is connected to the inner wall of the pulley 324. In this embodiment, the device rotates by contacting the film with the rotating column 311, which in turn drives the connecting column 323 to rotate synchronously. The rotation angle of the rotating shaft 321 is consistent with the rotation angle of the rotating column 311 through the pulley 324 and the transmission belt 325. Furthermore, the rubber sheet 322 is made of flexible rubber. When the rubber sheet 322 comes into contact with the film, the outer edge of the rubber sheet 322 contacts the film; at this time, the rubber sheet 322 will move the film, reducing the wrinkles generated in the film during the transportation process, ensuring the stability of film transportation, and reducing the possibility of film deviation during transportation. like Figure 1 , Figure 2 and Figure 5 As shown, the side limiting component 33 includes a round rod 331 fixedly connected to the inner wall of the frame 31. A limiting frame 332 is provided on the side of the round rod 331 close to the adjacent roller 2. Two connecting seats 333 are fixedly connected on the side of the limiting frame 332 away from the roller 2. A sleeve 334 is fixedly connected to the inner wall of the connecting seat 333. The lower end sleeve 334 is slidably connected to the surface of the round rod 331. The inner wall of the upper sleeve 334 is provided with a threaded shaft 335. The end of the threaded shaft 335 is rotatably connected to the inner wall of the frame 31. The surface of the threaded shaft 335 is threadedly connected to the inner wall of the adjacent sleeve 334. The end of the threaded shaft 335 extends to the outside of the frame 31 and is fixedly connected to an operating handle 336. In this embodiment, when the device is conveying the film, the two limiting frames 332 can limit the two sides of the film, forming a good limit during the film conveying process. When the film deviates, it can be protected by the two limiting frames 332. The threaded shaft 335 can be rotated synchronously by the knob operating handle 336. The threaded shaft 335 has threads on its surface. When moving synchronously with the adjacent sleeve 334, the connecting seat 333 will drive the two limiting frames 332 to move closer or further apart. Under the guidance of the lower sleeve 334 and the round rod 331, the limiting frame 332 is kept in line with the direction of the film, thus forming a good correction effect during the film conveying process.

[0019] Working principle: When the rotating column 311 rotates in contact with the film, it drives the connecting column 323 to rotate synchronously. The pulley 324 and the transmission belt 325 drive the rotating shaft 321 to rotate. When the rubber sheet 322 contacts the film, the outer edge of the rubber sheet 322 contacts the film and moves the film. The two limit frames 332 limit the two sides of the film. The knob operation handle 336 drives the threaded shaft 335 to rotate synchronously. The surface of the threaded shaft 335 is threaded. The adjacent sleeves 334 move synchronously. The connecting seat 333 drives the two limit frames 332 to move closer or further away from each other. Under the guidance of the lower sleeve 334 and the round rod 331, the limit frame 332 is kept in the same direction as the film conveying direction.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
