Description

Technical Field

[0001] The present application relates to the field of plastic film production equipment, and in particular to a high-stability plastic film folding device. Background Art

[0002] Plastic film refers to a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, which is used for packaging and as a lamination layer.

[0003] In the actual production process, it is necessary to fold the plastic film for subsequent processing. In the existing plastic film folding process, a limiting rod arranged to rotate is often used for conveying the plastic film. During the conveying process of the plastic film, there is a situation where the plastic film moves along the axis direction of the limiting rod, which is likely to affect the folding of the plastic film and needs to be improved. Utility Model Content

[0004] In order to reduce the situation where the plastic film moves along the axis direction of the limiting rod during the folding process, the present application provides a high-stability plastic film folding device.

[0005] A high-stability plastic film folding device provided by the present application adopts the following technical solutions:

[0006] A high-stability plastic film folding device includes a machine body. The machine body includes a mounting strip. The mounting strip is provided with a fixing strip. The fixing strip is provided with a limiting rod. The limiting rod rotates on the fixing strip. The rotation axis of the limiting rod is in the horizontal direction. The mounting strip is provided with a control rod one and a control rod two. One end of the control rod one away from the mounting strip is connected to one end of the control rod two away from the mounting strip. The mounting strip is provided with a limiting member. The limiting member slides on the mounting strip. The limiting member is used to limit the movement of the plastic film along the rotation axis direction of the limiting rod.

[0007] By adopting the above technical solutions, the limiting rod is arranged to rotate on the fixing strip, so as to facilitate the conveying of the plastic film for subsequent folding operations. The limiting member is provided. The limiting member is used to limit the movement of the plastic film, making the folding operation of the plastic film more stable. And the limiting member slides on the mounting strip, which is convenient for limiting plastic films of different sizes and improves the overall applicability.

[0008] Optionally, a sliding groove is provided on the side wall of the mounting strip. The extending direction of the sliding groove is the length direction of the mounting strip. The limiting member includes a sliding part and a limiting block. The sliding part slides on the groove wall of the sliding groove. The sliding direction of the sliding part is the extending direction of the sliding groove. The limiting block is used to abut against and limit the film.

[0009] By adopting the above technical solution, the sliding part and the limit block are provided, and the limit block contacts the plastic film to limit the movement of the plastic film along the axis direction of the limit rod, thereby facilitating the subsequent folding process of the plastic film.

[0010] Optionally, the sliding portion is provided with an adjustment groove, the bottom of the adjustment groove is provided with an adjustment spring, the end of the adjustment spring away from the bottom of the adjustment groove is connected to a limit block, the limit block slides on the wall of the adjustment groove, and the sliding direction of the limit block is the extension direction of the adjustment groove.

[0011] By adopting the above technical solution, in actual use, there is a situation where the plastic film contacts the limit block, resulting in the folding of the part of the plastic film close to the limit block, while the folding required for processing is the symmetrical folding of the plastic film. Therefore, the above-mentioned accidental folding is easy to affect the normal folding processing of the plastic film. Therefore, an adjustment spring is provided. When the limit block is under pressure, it moves toward the bottom of the adjustment groove, which not only plays a role in limiting the plastic film, but also reduces the folding of the edge of the plastic film, making the overall processing more stable.

[0012] Optionally, the sliding part is provided with an adjustment hole, the adjustment hole is located at one end of the sliding part away from the adjustment groove, the adjustment hole is threadedly connected with a threaded rod, the bottom of the adjustment groove is provided with an adjustment block, the adjustment block is located on the side of the adjustment spring close to the bottom of the adjustment groove, the adjustment spring connects the adjustment block and the limit block, the threaded rod is rotatably connected to the adjustment block, and the end of the threaded rod away from the limit block protrudes from the outer wall of the sliding part.

[0013] By adopting the above technical solution, a threaded rod is provided, and the position of the adjusting block is adjusted by rotating the threaded rod, thereby facilitating fine adjustment of the position of the adjusting block, thereby facilitating the limit block to contact the limit film and reducing the folding of the edge of the limit film.

[0014] Optionally, the control rod 1 is provided with a fixing frame, the fixing frame is connected to the control rod 2, the fixing frame is provided with a supporting rod, and the supporting rod is used to resist the plastic film.

[0015] By adopting the above technical solution, a fixing frame and a support rod are set, and the plastic film is supported by the support rod, which reduces the contact between the plastic film and the control rod and the control rod, and reduces the inconvenience of folding the plastic film due to sagging due to gravity.

[0016] Optionally, the support rod is rotated on the fixing frame, and the rotation axis of the support rod is parallel to the rotation axis of the limiting rod.

[0017] By adopting the above technical solution, the support rod is arranged to rotate on the fixed frame, thereby reducing the friction force on the plastic film when it passes through, and facilitating the transportation and subsequent processing of the plastic film.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. A limiting rod is arranged to rotate on the fixing strip, so as to facilitate the conveying of the plastic film for subsequent folding operations. A limiting member is arranged, and the limiting member is used to limit the movement of the plastic film, making the folding operation of the plastic film more stable;

[0020] 2. A sliding part and a limiting block are arranged. By the limiting block abutting against the plastic film, the movement of the plastic film along the axial direction of the limiting rod is restricted, so as to facilitate the subsequent folding processing of the plastic film;

[0021] 3. A fixing frame and a supporting rod are arranged. The plastic film is supported by the supporting rod, reducing the contact between the plastic film and the first control rod and the control rod, and reducing the situation that the folding of the plastic film is inconvenient due to the plastic film sagging under gravity.
