Description

Technical Field

[0001] This utility model relates to the field of plastic film folding technology, specifically to an improved plastic film three-folding device. Background Technology

[0002] Plastic film is a thin film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer. Plastic packaging and plastic packaging products are taking up an increasingly large share of the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. Plastic film is folded during processing to optimize the production process and reduce operating costs.

[0003] Depending on the actual product requirements, sometimes it is necessary to fold the plastic film product into three layers. Some previous folding structures achieved three layers through multiple folds, which resulted in poor folding effect, low yield rate, and relatively fixed applicable plastic film size, reducing the practicality of the device and making the overall use effect less than ideal.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an improved three-fold plastic film device, which has the advantages of being less prone to deformation, having a good folding effect, a high yield rate, and strong practicality, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned advantages of being less prone to deformation, having good folding properties, a high yield rate, and strong practicality, the specific technical solution adopted by this utility model is as follows:

[0009] An improved three-fold plastic film device includes a mounting platform, a folding section and a compaction section. Several sets of folding sections and compaction sections are evenly installed on the top of the mounting platform, and the inlet of the compaction section is located behind the outlet of the folding section. The folding section is composed of a bearing plate, a first side plate and a second side plate. The compaction section is composed of a support plate and an extrusion plate, and two sets of extrusion plates are symmetrically arranged.

[0010] Furthermore, a first adjustment groove is provided at the middle position of the top of the support plate, and a first bidirectional screw is installed inside the first adjustment groove. The first bidirectional screw is connected to the first side plate and the second side plate respectively through a connecting plate.

[0011] Furthermore, the support plate is located on the top surface of the mounting platform, and a second adjustment groove is provided below the support plate at the top of the mounting platform. A second bidirectional screw is installed inside the second adjustment groove, and the second bidirectional screw is connected to the extrusion plate through a connecting plate.

[0012] Furthermore, a knob is installed at one end of both the first bidirectional screw and the second bidirectional screw.

[0013] Furthermore, a folding cavity is provided between the first side plate and the second side plate, the plane formed by the first side plate and the second side plate has a V-shaped structure, and the cross-section of the folded part has a U-shaped structure.

[0014] Furthermore, a compaction groove is provided between the extrusion plates.

[0015] Furthermore, a receiving groove is provided on one side of the bottom of the extrusion plate.

[0016] Furthermore, fixed legs are symmetrically welded to both sides of the bottom of the mounting platform, and several sets of positioning holes are evenly opened on the surface of the fixed legs.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an improved three-fold plastic film device, which has the following beneficial effects:

[0019] (1) This utility model adopts a folding part and a compacting part. When in use, the cross-section of the folding part is "U" shaped and the plane is "V" shaped. The feed port is slightly wider than the plastic film material, and the width of the discharge port depends on the width of the three-fold plastic film. The left and right sides inside the folding part are different in height, so as to achieve the application effect of folding one side first, then folding the other side, and then folding three times at the discharge port. The compacting part is a flat groove with a curved surface. When the three-folded plastic film is stretched by the subsequent collection device and passes through this compacting part, it will be further compacted to consolidate the folding effect. Such a three-folded plastic film has the advantages of not being easily deformed, having a good folding effect, and a high yield.

[0020] (2) This utility model adopts a first bidirectional screw and a second bidirectional screw. Before the plastic film is folded, the operator can rotate the first bidirectional screw and the second bidirectional screw according to the different sizes of the plastic film to be processed. This causes the spacing between the folding cavities in the folding part and the spacing between the compaction grooves in the compaction part to change, so as to adapt to the processing operation of plastic films of different sizes. At the same time, each structure can be adjusted individually. In this way, multiple types of plastic films can be folded at one time, thereby expanding the application range of the device, improving the practicality of the device, improving the overall use effect, and facilitating better and more flexible subsequent processing. It has the advantage of strong practicality. Attached Figure Description

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an improved three-fold plastic film device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, an improved three-fold plastic film device according to an embodiment of the present invention includes a mounting platform 1, a folding section 2, and a compaction section 3. Several sets of folding sections 2 and compaction sections 3 are evenly installed on the top of the mounting platform 1, and the inlet of the compaction section 3 is located behind the outlet of the folding section 2. The folding section 2 is composed of a bearing plate 6, a first side plate 7, and a second side plate 9. The compaction section 3 is composed of a support plate 13 and an extrusion plate 12, and two sets of extrusion plates 12 are symmetrically arranged. The two sets are relative to a single compaction section 3. The structure and size of the first side plate 7, the second side plate 9, and the extrusion plate 12 can be adjusted according to personnel requirements during the production stage, which will not be elaborated here.

[0031] In one embodiment, a first adjustment groove 11 is provided at the top center of the support plate 6, and a first bidirectional screw 10 is installed inside the first adjustment groove 11. The first bidirectional screw 10 is connected to the first side plate 7 and the second side plate 9 respectively through a connecting plate 18.

[0032] In one embodiment, the support plate 13 is located on the top surface of the mounting platform 1, and a second adjustment groove 16 is provided below the support plate 13 at the top of the mounting platform 1. A second bidirectional screw 17 is installed inside the second adjustment groove 16. The second bidirectional screw 17 is connected to the extrusion plate 12 through a connecting plate 18. The connecting plate 18 is sleeved on both ends of the first bidirectional screw 10 and the second bidirectional screw 17, thereby driving the structure connected to its top.

[0033] In one embodiment, a knob 19 is installed at one end of the first bidirectional screw 10 and one end of the second bidirectional screw 17. The knob 19 is provided to facilitate the rotation of the first bidirectional screw 10 and the second bidirectional screw 17, thereby adjusting the structure to meet the folding operation of plastic films of different sizes, enrich the processing range of the device, and improve the practicality of the device.

[0034] In one embodiment, a folding cavity 8 is provided between the first side plate 7 and the second side plate 9. The plane formed by the first side plate 7 and the second side plate 9 has a V-shaped structure, and the cross-section of the folding part 2 has a "U"-shaped structure. The inlet is slightly wider than the plastic film material, and the outlet width depends on the width of the three-fold plastic film. The left and right sides inside the folding part 2 are at different heights, thereby achieving the application effect of folding one side first, then folding the other side, and then folding three times at the outlet.

[0035] In one embodiment, a compaction groove 14 is provided between the extrusion plates 12. The compaction groove 14 is provided so that the triple-folded plastic film is further compacted and consolidated when it is stretched by the subsequent collection device.

[0036] In one embodiment, a receiving groove 15 is provided on one side of the bottom of the extrusion plate 12. The receiving groove 15 is provided to provide a receiving area for the support plate 13 when the extrusion plate 12 is adjusted, thereby preventing the support plate 13 from affecting the left and right adjustment of the extrusion plate 12.

[0037] In one embodiment, mounting platform 1 has fixed legs 5 symmetrically welded on both sides of its bottom. The fixed legs 5 have several sets of positioning holes 4 evenly distributed on their surfaces. The positioning holes 4 are designed to secure the fixed legs 5 with fasteners such as bolts, thereby ensuring their stability. The fixed legs 5 are designed to fix the mounting platform 1 in a designated position, thereby facilitating the three-folding operation of the plastic film.

[0038] Working Principle: In actual use, the mounting platform 1 can be fixed between the plastic film output device and the plastic film winding device by fixing the legs 5 and the positioning holes 4 on their surfaces. Then, the plastic film is triple-folded by the folding part 2 and the compacting part 3 on the mounting platform 1. Since the cross-section of the folding part 2 is U-shaped and the plane is V-shaped, the feed port is slightly wider than the plastic film material, and the width of the discharge port depends on the width of the triple-folded plastic film. In addition, the left and right sides of the folding part 2 are at different heights, thus achieving the application effect of folding one side first, then folding the other side, and triple-folding at the discharge port. At the same time, the compacting part 3 is a curved flat groove. When the triple-folded plastic film is stretched by the subsequent collection device and passes through this compacting part 3, it will be further compacted and consolidated to consolidate the folding effect. The plastic film is not easily deformed, has a good folding effect, and a high yield rate. Before folding the plastic film, the operator can rotate the first bidirectional screw 10 and the second bidirectional screw 17 according to the different sizes of the plastic film to be processed. This changes the spacing of the folding cavities 8 in the folding part 2 and the spacing of the compaction grooves 14 in the compaction part 3, thus adapting to the processing of plastic films of different sizes. At the same time, each structure can be adjusted individually. This allows for the folding and processing of multiple types of plastic films at one time, thereby expanding the applicability of the device, improving its practicality, and enhancing the overall use effect. It facilitates better and more flexible subsequent processing. The device as a whole has the advantages of being not easily deformed, having a good folding effect, a high yield rate, and strong practicality.
