Description

Technical Field

[0001] This utility model specifically relates to the field of cutting equipment technology, and more specifically to a hydraulic adaptive length film cutting device. Background Technology

[0002] Film cutting is a crucial step in many industries, including film processing and packaging. Different production scenarios and product requirements necessitate precise length cutting of films. For example, in food packaging and electronic product packaging, there are strict standards for film length accuracy and cutting quality to ensure the standardization of packaging and the sealing performance of products.

[0003] Traditional hydraulic cutting equipment, due to factors such as the precision of its mechanical structure and the stability of its hydraulic pressure, struggles to guarantee high accuracy when cutting films of varying lengths. For instance, fluctuations in hydraulic pressure can cause instability in the downward pressure of the cutting blade, resulting in uneven cuts and significant length errors, which negatively impacts the assembly and use of subsequent products.

[0004] In the film winding process after cutting, most winding machines lack effective winding adjustment mechanisms. This can easily lead to uneven film tension during winding, resulting in irregularly shaped film rolls that become loose during later handling and may even require secondary winding, increasing production and time costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 In this embodiment of the present invention, a hydraulic adaptive length film cutting device includes a cutting body 1, an auxiliary moving device 2 and a hydraulic cutting device 3 are respectively installed on the upper end of the cutting body 1, and the hydraulic cutting device 3 is located in front of the auxiliary moving device 2; a receiving rack 4 is provided on the front side of the cutting body 1.

[0034] The auxiliary moving device 2 includes a tray 21, the two ends of which are fixedly installed on the inner side of the upper end of the cutting frame 11. The tray 21 is provided with a rectangular moving groove 23. The inner side of the moving groove 23 is symmetrically provided with slide rails. The slide rails are slidably connected to the sliding blocks 25. The bottom of the sliding blocks 25 is fixedly connected to the telescopic electric cylinders 24.

[0035] The upper ends of the sliding blocks 25 are all fixedly connected to the auxiliary limiting plate 26, the lower surface of the auxiliary limiting plate 26 is slidably connected to the support plate 21, and the auxiliary limiting plate 26 is provided in the form of a convex groove.

[0036] A second feeding device 31 is also installed at the upper end of the cutting frame 11. The second feeding device 31 is located in front of the auxiliary transition roller 22. A fixing plate 32 is provided at the upper end of the second feeding device 31. The two ends of the fixing plate 32 are fixedly connected to the upper end of the cutting frame 11.

[0037] A hydraulic upper cutter device 33 and a lifting lamp device 34 are installed on one side of the fixed plate 32. A lower cutter device 35 is provided at the lower end of the hydraulic upper cutter device 33 and the lifting lamp device. The lower cutter device 35 is fixedly installed on the inner side of the upper end of the cutting frame 11.

[0038] The fixed plate 32 is symmetrically provided with a hydraulic upper cutter clamping device 36 on the other side, and the end of the hydraulic upper cutter clamping device 36 is fixedly connected to the hydraulic upper cutter device 33.

[0039] By adopting the above technical solution, during use, the auxiliary moving device 2 can adaptively adjust according to the width of the film, realizing precise positioning and cutting of films of different specifications, which greatly improves the versatility of the equipment; at the same time, the hydraulic cutting device 3, with stable hydraulic drive, ensures high cutting precision, effectively reduces film size error, and achieves precise cutting of films with different length requirements, thus improving production quality.

[0040] In this embodiment, a feeding roller 14 is installed at the lower end of the cutting frame 11, and a main control panel 12 and an electrical box 13 are fixedly installed on one side.

[0041] The cutting frame 11 is equipped with a first feeding device 15 at the upper end, and the first feeding device 15 is located behind the auxiliary transition roller 22; the lower end of the first feeding device 15 is provided with a tensioning mechanism 16, which is located in front of the feeding roller 14 and its two ends are connected to the inner side of the cutting frame 11.

[0042] The hydraulic upper cutter device 33 and lower cutter device 35 are provided with a receiving plate 43 on one side. The bottom of the receiving plate 43 is fixedly connected to the angle adjustment mounting bracket 42. The angle adjustment mounting bracket 42 is provided with universal wheels 41 at the four corners of its bottom.

[0043] By adopting the above technical solutions, the main control panel 12 and electrical box 13 installed on the cutting frame 11 facilitate centralized control and management of the equipment by the operators; the angle adjustment mounting bracket 42 and casters 41 of the receiving rack 4 make the receiving process more flexible and convenient, adaptable to different production environments and needs, and improve the practicality and adaptability of the equipment.

[0044] The working principle of this utility model is as follows: the feeding roller 14 is responsible for the initial feeding of the rolled film raw material; the first feeding device 15 and the second feeding device 31 work together to convey the film forward; the tensioning mechanism 16 at the lower end of the first feeding device 15 can adjust the tension of the film to ensure that the film remains flat and stable during the feeding process and avoids loosening or wrinkling; the auxiliary transition roller 22 plays the role of transitioning and guiding the film so that the film can smoothly enter the subsequent processing area;

[0045] The telescopic electric cylinder 24 in the auxiliary moving device 2 drives the sliding block 25 to slide on the slide rail in the moving groove 23, thereby driving the two auxiliary limiting plates 26 to move in opposite directions. By adjusting the position of the auxiliary limiting plates 26, the film of different widths can be assisted in positioning and limiting, ensuring that the film will not shift laterally during the cutting process, thus providing a guarantee for accurate cutting.

[0046] Once the film is delivered to the designated position, the hydraulic cutting device begins operation. Driven by the hydraulic system, the upper hydraulic cutter 33 moves downward to cooperate with the lower cutting device 35 to cut the film. Due to the use of hydraulic drive, it can provide stable and large cutting pressure, ensuring that the cutting process is fast, accurate, and the cut edges are neat. The function of the upper cutting device 36 is to provide clamping force to the hydraulic upper cutting device 33 to prevent the hydraulic upper cutting device 33 from shifting position and causing slanted or uneven cuts.

[0047] During use, the auxiliary moving device 2 can adaptively adjust according to the width of the film, achieving precise positioning and cutting of films of different specifications, which greatly improves the versatility of the equipment; at the same time, the hydraulic cutting device 3, with stable hydraulic drive, ensures high cutting precision, effectively reduces film size error, and achieves precise cutting of films with different length requirements, thus improving production quality.

[0048] After the film is cut, it is collected by the receiving rack 4. The angle adjustment mounting bracket 42 at the bottom of the receiving plate 43 can adjust the angle of the receiving plate according to actual needs, so as to facilitate the sliding and collection of the film. The universal wheels 41 make the receiving rack easy to move and can flexibly adapt to different production layouts and receiving positions.

[0049] The central control panel 12 and electrical box 13 installed on the cutting frame 11 facilitate centralized control and management of the equipment by the operators; the angle adjustment mounting bracket 42 and casters 41 of the receiving rack 4 make the receiving process more flexible and convenient, adaptable to different production environments and needs, and improve the practicality and adaptability of the equipment.
