Description

Technical Field

[0001] The utility model belongs to the technical field of PE film production, and particularly relates to an anti-wrinkle film pressing mechanism for PE film production. Background Art

[0002] PE film is a material with good toughness and is widely used in the whole-piece collective packaging of products such as wine, cans, mineral water, various beverages, cloth, etc. The product has good flexibility, strong impact and tear resistance, is not easy to be damaged, is not afraid of moisture, has a large shrinkage rate, and has a wide range of uses.

[0003] When the existing PE film is wound after production, the PE film is relatively fragile and easily shakes during the winding process, which causes wrinkles in the wound PE film, thereby affecting the production quality of the PE film. In severe cases, a large amount of PE film will be scrapped, resulting in great economic losses. Therefore, we propose an anti-wrinkle film pressing mechanism for PE film production. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-wrinkle film pressing mechanism for PE film production, which provides a flattening component, specifically, inserting a counterweight plate into a placement seat, so that the pressure seat increases gravity and moves downward, then the pressure roller inside the fixed seat and the pressure roller inside the pressure seat will clamp the PE film tightly, then when the PE film moves on the pressure roller, it will be flattened by the support frame, thereby avoiding the occurrence of wrinkles, and at the same time, due to the squeezing, there will be no shaking during the transportation process, which solves the problem that the PE film is relatively fragile and prone to shaking during the winding process, thereby causing wrinkles in the wound PE film, thereby affecting the production quality of the PE film, and in severe cases causing a large amount of PE film to be scrapped.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an anti-wrinkle film pressing mechanism for PE film production, comprising a workbench, a fixed plate is fixedly connected to the top of the workbench, a flattening assembly is arranged on the front of the fixed plate, conveying rollers are arranged on the left and right sides of the flattening assembly, and a top plate is fixedly connected to the front of the fixed plate;

[0007] The flattening assembly includes a fixed seat, a pressure seat is arranged above the fixed seat, the fixed seat and the pressure seat are rotatably connected to a plurality of pressure rollers on the corresponding side, the top of the pressure seat is fixedly connected to a placement seat, a counterweight plate is inserted inside the placement seat, and the flattening assembly is arranged, specifically, the counterweight plate is inserted into the placement seat, so that the pressure seat increases the gravity and moves downward, then the pressure rollers inside the fixed seat and the pressure rollers inside the pressure seat will clamp the PE film tightly, and when the PE film moves on the pressure rollers, it will be flattened by the support frame, thereby avoiding wrinkles, and at the same time, due to the squeezing, no shaking will occur during the transportation process.

[0008] Furthermore, a support frame is fixedly connected to the bottom of the fixed seat, and the bottom of the support frame is fixedly connected to the top of the workbench. The left and right sides of the pressure seat are fixedly connected to connecting frames. The two connecting frames are symmetrically arranged with the counterweight plate as the center. The parts contained in the two connecting frames are the same. When the counterweight plate is not added, the gap between the pressure seat and the fixed seat is larger, so the PE film can be smoothly passed through the pressure seat.

[0009] Furthermore, a limiting hole is opened inside the connecting frame, the inner wall of the limiting hole is slidably connected to the limiting rod, a spring is sleeved on the outer side of the limiting rod, the top of the limiting rod is fixedly connected to the bottom of the top plate, and when the pressure seat moves upward, it will drive the connecting frame to slide on the limiting rod, so that the pressure seat can be more stable and move in a straight line, and at the same time the spring will be stretched.

[0010] Furthermore, an arc-shaped adjusting rod is arranged on the right side of the pressure seat, a supporting plate is arranged above the arc-shaped adjusting rod, a limiting ring is fixedly connected to the top of the arc-shaped adjusting rod, a threaded rod is rotatably connected to the inner wall of the limiting ring, the top of the threaded rod passes through the supporting plate and extends to the outside, and a turning handle is fixedly connected to the top of the threaded rod. By arranging the arc-shaped adjusting rod, the PE film will be stretched when the arc-shaped adjusting rod moves downward, thereby increasing the tension, and the tension will be reduced when the arc-shaped adjusting rod moves upward. At the same time, after the flattened PE film contacts the arc-shaped adjusting rod, it can be flattened again by the arc-shaped adjusting rod, thereby improving the winding effect of the PE film.

[0011] Furthermore, a limiting plate is provided on the front side of the limiting ring, the bottom of the limiting plate is fixedly connected to the top of the arc-shaped adjusting rod, the back side of the limiting plate is in contact with the front side of the supporting plate, and the outer surface of the threaded rod is threadedly connected to the supporting plate. Since the limiting plate at the top of the arc-shaped adjusting rod moves on the front side of the supporting plate, it can limit the arc-shaped adjusting rod, so that the arc-shaped adjusting rod can move in a straight line.

[0012] Furthermore, the front sides of the two conveying rollers are rotatably connected to support seats, the bottoms of the two support seats are fixedly connected to the top of the workbench, the outer surfaces of the two conveying rollers are fixedly connected to convex rings, and an auxiliary roller is arranged above the conveying roller on the right side. The support seats are used to support the conveying rollers, and the convex rings are used to prevent the PE film from deviating, thereby reducing the deviation of the PE film during transportation.

[0013] Furthermore, the front side of the auxiliary roller is rotatably connected to a fixed frame, the back side of the fixed frame is fixedly connected to the front side of a fixed plate, the back sides of the two conveying rollers are rotatably connected to the fixed plate, the front side of the support seat located on the right side is fixedly connected to a motor, the back side output end of the motor is fixedly connected to the front side of the conveying roller located on the right side, and the auxiliary roller is used to cooperate with the conveying roller, so that the conveying roller can smoothly drive the PE film to move.

[0014] Furthermore, the top of the spring is fixedly connected to the bottom of the top plate, the bottom of the spring is fixedly connected to the top of the connecting frame, the back of the support plate is fixedly connected to the front of the fixed plate, and the bottom of the arc-shaped adjustment rod is arranged in an arc shape. Since the bottom of the arc-shaped adjustment rod is arranged in an arc shape, the PE film can pass through the arc-shaped adjustment rod smoothly, and at the same time, the arc-shaped adjustment rod increases the tension of the PE film so that it can be better wound.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model sets a flattening component, specifically inserts a counterweight plate into a placement seat, so that the pressure seat increases gravity and moves downward, and the pressure roller inside the fixed seat and the pressure roller inside the pressure seat will clamp the PE film tightly, and when the PE film moves on the pressure roller, it will be flattened by the support frame, thereby avoiding wrinkles. At the same time, due to the squeezing, there will be no shaking during the transportation process.

[0017] 2. The utility model sets an arc-shaped adjustment rod. Specifically, when the arc-shaped adjustment rod moves downward, the PE film will be stretched, thereby increasing the tension. When the arc-shaped adjustment rod moves upward, the tension is reduced. At the same time, after the flattened PE film contacts the arc-shaped adjustment rod, it can be flattened again by the arc-shaped adjustment rod, thereby improving the winding effect of the PE film.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
