[0002] PE plastic bag film possesses high toughness, tensile strength, and abrasion resistance, while also exhibiting good moisture-proof, dust-proof, and insect-proof properties, making it a widely used plastic packaging material. During the processing of PE plastic bag film, the cutting device can precisely cut the film according to preset dimensions and shapes, ensuring product consistency and standardization.
[0003] When the cutting device cuts PE plastic bag film, it uses a hydraulic cylinder to drive the cutter to perform the cutting work. During this process, the cutter will produce film debris. This film debris will adhere to the cutter. The accumulation of debris will cause poor cutting or blade blockage, which will easily lead to wear of the cutter and affect the cutting effect. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing film debris adheres to the cutter, causing poor cutting or blade blockage, which in turn leads to cutter wear and affects the cutting effect. Therefore, a cutting device for processing PE plastic bags is proposed.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Reference Figures 1-6 This embodiment provides a cutting device for processing PE plastic bag film, including a base 1, a worktable 2 on the top of the base 1, a top plate 4 arranged parallel to the worktable 2 via a column 3 on the base 1, a hydraulic cylinder 5 fixedly installed on the top plate 4, and a mounting seat 6 located below the top plate 4 at the output end of the hydraulic cylinder 5, a cutter 7 at the bottom of the mounting seat 6, and a scraping assembly 8 for cleaning film debris from the surface of the cutter 7 on the mounting seat 6.
[0026] In this invention, the cutting device is installed and fixed on the base 1. The PE plastic bag film to be cut is placed and fixed on the worktable 2 by the clamp. Then, the hydraulic cylinder 5 on the top plate 4 is activated and drives the mounting base 6 to move on the column 3. When the hydraulic cylinder 5 drives the mounting base 6 to descend, the cutter 7 on the mounting base 6 contacts the film on the worktable 2. As the cutter 7 continues to descend, the cutter 7 cooperates with the blade groove on the worktable 2 to cut the film. When the cutter 7 completes one cutting action, the scraping component 8 scrapes off the film debris attached to the cutter 7, avoiding debris from adhering to the cutter 7 and causing poor cutting or blade blockage. At the same time, it avoids the film moving during cutting and causing cutting errors, effectively improving cutting efficiency and cutting accuracy.
[0027] Specifically, such as Figure 1 and Figure 2As shown, the scraping assembly 8 includes a fixed sleeve 81 fixed on the mounting base 6, a connecting rod 82 movably connected to the fixed sleeve 81, a scraper 84 that fits against the cutter 7 is provided at the bottom of the connecting rod 82 through the fixing plate 83, and a first spring 85 is sleeved on the connecting rod 82 at the position between the fixed sleeve 81 and the fixing plate 83.
[0028] When the hydraulic cylinder 5 drives the cutter 7 to move downward, the scraping assembly 8 also moves downward. Then, the fixing plate 83 and the scraper 84 press against the film on the worktable 2. As the cutter 7 continues to descend, the fixing plate 83 compresses the first spring 85 on the connecting rod 82. As the cutter 7 completes the cutting action and rises through the hydraulic cylinder 5, the fixing plate 83 and the scraper 84 leave the worktable 2. At this time, under the reset action of the first spring 85 at the bottom of the fixing sleeve 81, the scraper 84 on the fixing plate 83 moves in the opposite direction to the cutter 7. The scraper 84 scrapes off the debris attached to the cutter 7, preventing debris from adhering to the cutter 7 and causing poor cutting or blade blockage. This reduces the downtime required for cleaning the blade and also prevents wear on the cutter 7 caused by debris, effectively improving the cutting effect.
[0029] It should be noted that when the cutter 7 descends, the fixing plate 83 and the scraper 84 first contact the film on the worktable 2. As the cutter 7 continues to descend, the fixing plate 83 and the scraper 84 press and fix the film on the worktable 2, avoiding the film from moving during cutting and causing cutting errors, thus effectively improving cutting efficiency and cutting accuracy.
[0030] Specifically, such as Figure 2 and Figure 3 As shown, the scraper 84 is movably connected to the fixed plate 83 via the shaft 841, and a second spring 842 is sleeved on the shaft 841 at the position between the fixed plate 83 and the scraper 84.
[0031] The scraper 84 can move laterally on the fixed plate 83 via the shaft 841 and the second spring 842. Since the cutting surface of the cutter 7 is inclined, the retractable scraper 84 can adapt to the cutting surface of the cutter 7, ensuring that the scraper 84 can effectively scrape off the debris attached to the cutter 7 and improve the cleaning effect.
[0032] It should be noted that the end of the shaft 841 away from the scraper 84 is provided with a locking nut 844 that abuts against the fixing plate 83 via a second threaded end 843. After the locking nut 844 is unscrewed, the shaft 841 of the scraper 84 can be pulled out from the fixing plate 83. When installing the scraper 84, the shaft 841 is inserted into the fixing plate 83, and then the locking nut 844 is screwed on. This facilitates the installation and removal of the scraper 84, and thus makes it easier to maintain and clean the scraper 84.
[0033] Specifically, such as Figure 2 and Figure 4 As shown, a rubber pad 832 is provided at the bottom of the fixing plate 83 via a slot 831, and the bottom plane of the rubber pad 832 is lower than the bottom plane of the fixing plate 83.
[0034] As the cutter 7 descends, the fixed plate 83 presses down onto the worktable 2. At this time, the rubber pad 832 first comes into contact with the worktable 2. The rubber pad 832 can press and fix the film on the worktable 2 to prevent the film from moving, and it can also play a buffering role to prevent the hydraulic cylinder 5 from having too much impact force, which could damage the fixed plate 83 and the scraper 84.
[0035] It should be noted that, as Figure 5 As shown, a limiting nut 822 is provided at the top of the connecting rod 82 via a first threaded end 821. The diameter of the limiting nut 822 is larger than the inner diameter of the fixing sleeve 81. When the limiting nut 822 is screwed onto the first threaded end 821, it acts as a limit to prevent the connecting rod 82 from detaching from the fixing sleeve 81. When the limiting nut 822 is unscrewed from the first threaded end 821, the connecting rod 82 can be disassembled, facilitating maintenance and repair of the scraper assembly 8.
[0036] Specifically, such as Figure 1 and Figure 6 As shown, the cutter 7 is detachably connected to the mounting base 6 via a sleeve 61 at the bottom of the mounting base 6. The sleeve 61 is provided with a fastening bolt 62 that passes through the cutter 7, and a gasket 63 is provided between the inner wall of the sleeve 61 and the cutter 7. Guide sleeves 64 that cooperate with the column 3 are provided at both ends of the mounting base 6.
[0037] When installing the cutter 7, it is first inserted into the sleeve 61 at the bottom of the mounting base 6, and then the cutter 7 is fixed to the sleeve 61 using the fastening bolt 62. When removing the cutter 7, the fastening bolt 62 can be unscrewed. The gasket 63 is made of rubber, which can improve the stability of the cutter 7 in the sleeve 61. The mounting base 6 is slidably connected to the column 3 through the guide sleeve 64. The tight fit between the guide sleeve 64 and the column 3 can ensure accurate guidance during the lifting and moving process.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
