Description

Technical Field

[0001] The invention relates to the technical field of film production, in particular to a film traction and winding machine. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. A winder is needed in the film production process. The winder is a type of winding machinery and is widely used in metallurgy, papermaking and printing, chemical fiber, and textile printing and dyeing industries. The winder pushes the film through the traction roller and drives the winding drum to rotate through the winding roller to wind the film.

[0003] In the prior art, the operation of the winder when winding various film materials is relatively complicated, specifically including the following problems: during winding, the film is both the object to be processed and participates in the transmission of motion and power as a transmission member. The film itself is neither a rigid body nor a pure elastic body, and exhibits strong viscoelastic characteristics, which makes its dynamic and motion characteristics more complex. Therefore, the film often has wrinkles, uneven winding and unsmoothness during the winding process, thereby affecting the quality of the finished product after the film is wound; due to different applicable scopes, the lengths of the films produced are also different. The prior art lacks a mechanism to guide the two sides of the film when the film is wound, which easily causes the position of the film to shift during the winding process, affecting the winding quality. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention designs a film traction and winding machine, which can solve the problems in the prior art, such as wrinkles in the film winding process resulting in uneven winding, lack of a film limiting guide mechanism, and displacement of the film position during the winding process, which affects the winding quality.

[0006] As a preferred solution of the present invention, a group of first guide slide bars are fixedly connected inside the adjustment groove, a group of first return springs are sleeved on both ends of the first guide slide bars, and a group of first limiting slide bars are opened on both sides of the inner wall of the adjustment groove.

[0008] In this solution, the connecting block is slidably connected to the first guide sliding rod through the first sliding hole, and the height of the traction roller is adjusted according to the tension of the film during transportation, so as to avoid the film being too tight during transportation.

[0009] As a preferred solution of the present invention, the limiting material guiding structure is composed of a bidirectional threaded rod, a rotating handle, a second guide sliding rod and a limiting frame.

[0010] As a preferred solution of the present invention, a bidirectional threaded rod is rotatably connected to the interior of the traction frame below the traction roller, one end of the bidirectional threaded rod is fixedly connected to a turning handle at the outside of the traction frame, and anti-slip grooves are provided on the outside of the turning handle. Both sides of the bidirectional threaded rod are fixedly connected to a group of second guide slide bars inside the two groups of mounting frames, and the top of the frame is slidably connected to two groups of limit frames at the directional slide groove.

[0011] As a preferred solution of the present invention, a group of directional pulleys are rotatably connected to the bottom of the limit frame and the position corresponding to the directional slide groove, the limit frame is slidably connected to the directional slide groove through the directional pulley, a threaded adjustment hole is opened at the position of the limit frame corresponding to the bidirectional threaded rod, the limit frame is threadedly connected to the bidirectional threaded rod through the threaded adjustment hole, a second sliding hole is opened at the position of the limit frame corresponding to the second guide slide rod, and the limit frame is slidably connected to the second guide slide rod through the second sliding hole.

The limit frame is slidably connected to the guide roller through the arc groove, and a sponge pad is fixedly connected to the inner wall of the arc groove.

[0013] In this solution, the rotating handle drives the bidirectional threaded rod to rotate, so that the two sets of limit frames are threadedly connected to the bidirectional threaded rod through the threaded adjustment holes, and the arc groove is used to slide with the guide roller to adjust the spacing according to the width of the film.

A second transmission gear is installed on the side of the motor corresponding to the winding frame, and the second transmission gear is meshed with the first transmission gear.

[0016] In this solution, the motor drives the second transmission gear to rotate, so that the second transmission gear meshes with the first transmission gear, thereby driving the winding rod to wind up the film, which facilitates the loading, unloading and replacement of the winding rod.

[0017] The cam is provided with a second return spring, and the second return spring is provided with a third return spring on the sliding frame and a third return spring on the sliding frame.

[0018] In this solution, the second return spring pushes the sliding frame through its own elasticity to slidely connect with the third guide sliding rod through the third sliding hole, so that the flattening roller is always in contact with the film rolled up on the outside of the winding rod, flattens the film during the winding process, and prevents the film from being too loose after winding.

[0019] The beneficial effects of the present invention are: 1. The traction roller of the present invention is used to traction and guide the film transmitted between the guide rollers. When the film is too tight during transmission, the traction roller is stressed by the film so that the connecting blocks at both ends are slidably connected with the first guide slide rod by using the first slide hole, and the first reset spring under the connecting block is pressed down to reduce the height of the traction roller to relieve the tightness of the film. When the transmission tension of the film returns to normal, the first reset spring under the connecting block resets by its own elasticity to push the traction roller to reset, thereby automatically regulating the tension of the film transmission; 2. The present invention provides a limiting material guide structure, and uses a rotating handle to drive the bidirectional threaded rod to rotate, so that two sets of limiting frames are threadedly connected with the bidirectional threaded rod through threaded adjustment holes, and the spacing is adjusted according to the width of the film, and the two sides of the film in the winding process are limited, so as to avoid the technical problem that the position of the film is easily offset during the conveying process, resulting in an unsightly finished product after the film is rolled; 3. In the present invention, by means of the flattening mechanism, when the winding rod is winding the film, the second return spring pushes the sliding frame through its own elasticity to make a sliding connection with the third guide sliding rod through the third sliding hole, so that the flattening roller is always in contact with the film being wound on the outside of the winding rod, and the film being wound is flattened, thereby avoiding wrinkles or uneven winding of the film during the winding process, and improving the product quality after the film is wound.
