Description

Technical Field

[0001] This utility model relates to the technical field of PE film processing equipment, and in particular to a PE stretch film slitting and processing device that facilitates quick film replacement. Background Technology

[0002] In the field of PE stretch film slitting, with the increasing demand for flexible production in the packaging industry, equipment needs to frequently switch between different specifications of film rolls (such as width, thickness, and material) to adapt to diverse orders. However, the film roll fixing and replacement process of traditional slitting equipment has significant drawbacks, resulting in low production efficiency and cumbersome operation. The fixing structure of traditional equipment is usually only compatible with 1-2 types of winding rolls. When the production task involves multiple film rolls (such as narrow-width e-commerce packaging film and wide-width industrial film), multiple sets of fixtures need to be configured, increasing equipment costs and warehousing pressure.

[0003] For the reasons mentioned above, this application proposes a slitting and processing device that can quickly change different PE stretch film winding drums. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a slitting and processing device that can quickly change different PE stretch film winding drums.

[0005] The technical solution of this utility model is: a PE stretch film slitting and processing device that facilitates quick film replacement, including a slitting equipment body and a guide roller for guiding and conveying the PE stretch film. The slitting equipment body is also equipped with a fixing component for fixing the position of the PE stretch film winding drum.

[0006] The fixing component includes a first cylinder fixedly connected to the side of the main body of the slitting equipment. The output end of the first cylinder is connected to a fixing frame. The outer ring of the fixing frame is also provided with a first sleeve, a second sleeve, and a third sleeve with successively increasing diameters.

[0007] Optionally, mounting blocks are fixedly connected to both the upper and lower sides of the fixing frame, and mounting slots are provided in the mounting blocks, in which a second cylinder is installed.

[0008] Optionally, the first sleeve, the second sleeve, and the third sleeve are all cylindrical structures, and the output end of the second cylinder is in contact with one end of the first sleeve, the second sleeve, and the third sleeve respectively when in operation.

[0009] Optionally, the first sleeve, the second sleeve, and the third sleeve are all provided with limit guide holes, and guide rods are provided in the limit guide holes.

[0010] Optionally, one end of the guide rod is located inside the limiting guide hole, and the other end is fixedly connected to the side wall of the main body of the slitting equipment.

[0011] Optionally, the cross-section of the fixing frame is a "U" shaped structure, and the inner wall of the fixing frame is fixedly connected to the output end of the first cylinder.

[0012] Optionally, the inner wall of the main body of the slitting device is further provided with a fixed slitting plate, and a slitting component for slitting PE wrapping film is provided above the fixed slitting plate.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention uses a fixing component to securely mount the PE stretch film rewinding cylinder, thereby achieving stable PE stretch film cutting and processing.

[0015] Furthermore, by setting up first, second, and third sleeves of different diameters, and in conjunction with the setting of the second cylinder, when taking up PE wrapping film of different pipe diameters, the first, second, or third sleeves are pushed accordingly, thereby realizing the installation of PE wrapping film of different pipe diameters.

[0016] In summary, this invention enables rapid positioning and fixing of winding drums with different inner diameters without frequent replacement of fixing components. It allows for quick installation of PE stretch film, is suitable for flexible production scenarios with a variety of products, and aligns with the packaging industry's trend towards high efficiency and intelligence.

[0033] Example 1

[0034] like Figure 1As shown, the PE stretch film slitting and processing device for quick film replacement proposed in this utility model includes a slitting equipment body 1 and a guide roller 2 for guiding and conveying the PE stretch film. The slitting equipment body 1 is also equipped with a fixing component 4 for fixing the position of the PE stretch film winding drum. The inner wall of the slitting equipment body 1 is also provided with a fixing slitting plate 3. A slitting component 5 for slitting the PE stretch film is provided above the fixing slitting plate 3. The PE stretch film flattened on the fixing slitting plate 3 is slitting in combination with the setting of the slitting component 5.

[0035] like Figures 2-5 As shown, the fixing component 4 includes a first cylinder 41 fixedly connected to the side of the main body 1 of the slitting equipment. The output end of the first cylinder 41 is connected to a fixing frame 42. The fixing frame 42 has a "U" shaped cross-section, and the open end of the fixing frame 42 is sleeved on the outside of the first cylinder 41. See the attached diagram for details. Figure 2 As shown; the inner wall of the fixing frame 42 is fixedly connected to the output end of the first cylinder 41; mounting blocks are fixedly connected to both the upper and lower sides of the fixing frame 42, and mounting slots 420 are opened in the mounting blocks. The second cylinder 421 is installed in the mounting slots 420. The outer ring of the fixing frame 42 is also provided with a first sleeve 43, a second sleeve 44, and a third sleeve 45 with successively increasing diameters. The first sleeve 43, the second sleeve 44, and the third sleeve 45 are all cylindrical structures, and the output of the second cylinder 421 is... When in use, the output end contacts one end of the first sleeve 43, the second sleeve 44, and the third sleeve 45 respectively. The output end of the second cylinder 421 is pushed out, so that the output end of the second cylinder 421 contacts one end of the second sleeve 44. Thus, when the first cylinder 41 pushes, it pushes the second sleeve 44. Similarly, when the third sleeve 45 is pushed, the output end of the second cylinder 421 is pushed upward so that the output end contacts one end of the third sleeve 45.

[0036] like Figure 2 and Figure 5 As shown, the first set of cylindrical components 43, the second set of cylindrical components 44 and the third set of cylindrical components 45 are all provided with limit guide holes, and a guide rod 46 is provided in the limit guide hole. One end of the guide rod 46 is located in the limit guide hole, and the other end is fixedly connected to the side wall of the main body 1 of the slitting equipment.

[0037] In this embodiment, when clamping and fixing the PE stretch film with a small paper tube diameter, the first cylinder 41 is activated, causing the output end of the first cylinder 41 to engage the first sleeve 43 with the mounting blocks on both sides. This allows the mounting blocks to contact and push one end of the first sleeve 43, thereby pushing the first sleeve 43 along the guide rod 46 and the limiting guide hole. This fixes the position of the PE stretch film paper tube between the two sets of fixing components 4. The two sets of first sleeves 43 contact the inner wall of the paper tube, clamping the PE stretch film paper tube. A rubber sleeve for limiting is also fitted around the outer ring of the corresponding first sleeve 43. Figure 5 and Figure 4 As can be seen, the rubber sleeves limit the position of both ends of the PE stretch film tube, thereby achieving further position fixation, making the installation of the PE stretch film tube faster and eliminating the need for frequent replacement of fixing components.

[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
