Description

Technical Field

[0001] This utility model relates to a cutting device for processing, and in particular to a cutting device for processing plastic film applied in the field of cutting devices. Background Technology

[0002] Plastic film processing cutting equipment is an automated or semi-automatic processing device specifically designed for the precise cutting and slitting of plastic films. It is widely used in the production and processing of plastic films in fields such as plastic packaging, agricultural covering, and industrial protection.

[0003] Chinese patent CN218593153U discloses a cutting device for processing plastic film, which includes a worktable. Baffles are welded to both sides of the upper end of the worktable, and a bracket is provided on the upper end of the baffle. A first fixing plate is provided on the upper end of the worktable located on one side of the baffle, which can ensure the flatness of the plastic film during cutting. With the assistance of the mounting frame, electro-hydraulic push rod and lifting plate, the straight up and down cutting blade can also ensure the flatness of the plastic film cut compared with the horizontally moving cutting blade, preventing the plastic film from accumulating and wrinkling when it is cut again, thus ensuring the cutting quality.

[0004] Chinese patent CN209903282U discloses a cutting device for processing plastic film, including a base, a fixed frame fixedly connected to the top of the base, a feed inlet and a discharge outlet respectively opened on the two side walls of the fixed frame, a cutting frame fixedly connected to the bottom end of the output shaft of the hydraulic cylinder, a cutting table provided below the cutting frame, a support leg fixedly connected to the bottom of the cutting table, and the bottom end of the support leg fixedly connected to the base.

[0005] During the use of cutting devices for plastic film processing, traditional blades and the plastic film to be processed have poor compatibility. When the blade width does not match the plastic film width, the blade is subjected to uneven force during the cutting process, and the blade edge is subjected to excessive pressure in some areas, which can easily lead to chipping or irregular wear. This not only shortens the service life of the blade, but also requires frequent blade replacement, increasing the maintenance cost of the equipment and the production downtime. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that during the use of the cutting device for plastic film processing, the traditional blades and the plastic film to be processed have poor compatibility. When the width of the blade does not match the width of the plastic film, the blade is subjected to uneven force during the cutting process, and the blade edge is subjected to excessive pressure in some areas, which easily leads to chipping or irregular wear. This not only shortens the service life of the blade, but also requires frequent blade replacement, increasing the maintenance cost of the equipment and the production interruption time.

[0007] The device includes an equipment component, an adjustable cutting component fixedly connected to the upper end of the equipment component, an auxiliary lubrication component fixedly connected to the upper end of the adjustable cutting component, a liquid equalization component inside the auxiliary lubrication component, and a guide component at the upper end of the equipment component.

[0008] The equipment components include an equipment frame, with a feeding platform panel fixedly connected to the upper left side of the equipment frame and a placing platform panel fixedly connected to the upper right side of the equipment frame. The adjustable cutting component includes two side column frames fixedly connected to the equipment frame, with a hydraulic actuator fixedly connected to the upper end of each side column frame. A rotating spindle is installed between the two side column frames, with multiple tool holders fixedly connected to the outer end of the rotating spindle. A tool body is installed at the inner end of each tool holder, and multiple threaded connectors are installed between the tool body and the corresponding tool holder. A motor is externally connected to the rotating spindle.

[0009] The auxiliary lubrication assembly includes a hollow chamber located directly above the rotating spindle. The upper end of the hollow chamber is fixedly connected to a built-in electrically operated liquid outlet valve reservoir extending into the hollow chamber. Multiple springs are symmetrically fixedly connected to the left and right inner walls of the hollow chamber, and sponge-impregnated strips are fixedly connected to the corresponding multiple springs.

[0010] In the above-mentioned cutting device for plastic film processing, the external motor drives the rotating spindle, the tool holder and the tool body to rotate to achieve cutting, which facilitates quick switching according to the width of the plastic film, avoids irregular wear of the tool, extends its service life and reduces replacement costs.

[0011] As a further improvement of this application, the liquid homogenizing assembly includes a liquid distribution groove bar located between the output end of the built-in electric liquid outlet valve storage tank and the sponge immersion plate.

[0012] As a further improvement of this application, the lower end of the dispensing tank bar is fixedly connected with multiple one-way electric drain valves, and the lower end of the hollow chamber is fixedly connected with two silicone bottom plates.

[0013] As a further improvement of this application, the tool body extends into the hollow chamber through two silicone bottom sheets, and the outer wall of the tool body and the two sponge-impregnated strips are in contact with each other at their closest ends.

[0014] As another improvement of this application, the guide assembly includes grooved guide strips respectively formed on the conveyor panel and the placement panel.

[0015] As a further improvement to this application, the upper front and rear sides of the conveying platform panel and the placing platform panel are symmetrically and fixedly connected with limiting side strips, and the two corresponding limiting side strips are fixedly connected with electric push rods at their close ends.

[0016] As a further improvement to this application, the output end of the electric push rod is fixedly connected to a linkage abutment side plate, and the linkage abutment side plate and the corresponding grooved guide strip are slidably connected.

[0017] In summary, the equipment frame in this solution provides stable support for all components. The conveying platform and the placement platform orderly transport and place the plastic film. An external motor drives the rotating spindle, blade holder, and blade body to rotate for cutting, facilitating quick switching according to the width of the plastic film, avoiding irregular blade wear, extending service life, and reducing replacement costs. The auxiliary lubrication component and the liquid distribution component work together, with a built-in electric liquid outlet valve and storage tank precisely distributing lubricating oil. The lubricating oil is then evenly dripped onto the sponge soaking plate through the liquid distribution trough and one-way electric drain valve. Springs ensure close contact between the sponge soaking plate and the blade body, achieving continuous and uniform lubrication, reducing frictional resistance, improving cutting smoothness, reducing blade wear, and ensuring stable cutting quality. A silicone bottom sheet prevents lubricating oil leakage, avoiding waste and environmental pollution, making it more energy-efficient and environmentally friendly. Unused blades on the top can enter the auxiliary maintenance process to further extend their life and improve subsequent cutting results. Attached Figure Description

[0027] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figures 1-5 A cutting device for processing plastic film is shown, including a device component 1, an adjustable cutting component 2 fixedly connected to the upper end of the device component 1, an auxiliary lubrication component 3 fixedly connected to the upper end of the adjustable cutting component 2, a liquid equalization component 4 disposed inside the auxiliary lubrication component 3, and a guide component 5 disposed at the upper end of the device component 1.

[0030] Equipment component 1 includes equipment frame 100. A material conveying platform 101 is fixedly connected to the upper left side of equipment frame 100, and a material placement platform 102 is fixedly connected to the upper right side of equipment frame 100. Adjustable cutting component 2 includes two side column frames 200 fixedly connected to equipment frame 100. A hydraulic driver 202 and an HPM series electric hydraulic push rod are fixedly connected to the upper end of the side column frames 200. A rotating spindle 201 is installed between the two side column frames 200. Multiple tool holders 203 are fixedly connected to the outer end of the rotating spindle 201. A tool body 204 is installed at the inner end of the tool holder 203. Multiple threaded connectors 205 are installed between the tool body 204 and the corresponding tool holder 203. A motor is externally connected to the rotating spindle 201. A YE2 series three-phase asynchronous motor can be selected. The motor is fixed to the outside of the side column frames (200).

[0031] The auxiliary lubrication assembly 3 includes a hollow chamber 300 located directly above the rotating spindle 201. The upper end of the hollow chamber 300 is fixedly connected to a built-in electric liquid outlet valve storage tank 301 with the output end extending into the hollow chamber 300. An SLDF series electromagnetic liquid outlet valve can be selected. Multiple springs 303 are symmetrically fixedly connected to the left and right inner walls of the hollow chamber 300, and sponge soaking strips 304 are fixedly connected to the corresponding multiple springs 303.

[0032] The liquid distribution assembly 4 includes a liquid distribution trough 400, which is located between the output end of the built-in electric discharge valve storage tank 301 and the sponge immersion strip 304. The lower end of the liquid distribution trough 400 is fixedly connected to multiple one-way electric discharge valves 401, which can be DFD series one-way solenoid valves. The lower end of the hollow chamber 300 is fixedly connected to two silicone bottom pieces 302. The cutter body 204 extends into the hollow chamber 300 through the two silicone bottom pieces 302, and the outer wall of the cutter body 204 and the two sponge immersion strips 304 are in contact with each other. The built-in electric discharge valve storage tank (301) is opened and closed at preset intervals by a PLC controller.

[0033] Figures 1-5In this solution, the equipment frame 100 in equipment component 1 provides stable support for each component. The upper left side conveyor panel 101 is used to convey the plastic film to be cut, while the right side placement panel 102 is used to place the cut plastic film. When the device is started, the adjustable cutting component 2 begins cutting. Two side column frames 200 fixed to the equipment frame 100 provide support for the entire cutting component. The upper hydraulic actuator 202 can adjust the cutting height to accommodate plastic films of different thicknesses. An external motor drives the rotating spindle 201 between the two side column frames 200 to rotate. Multiple tool holders 203 at the outer end of shaft 201 rotate accordingly, and the tool body 204, installed at the inner end of the tool holder 201 via threaded connector 205, cuts the plastic film. Different widths of tool body 204 can be switched to cut plastic films of varying widths, facilitating quick switching between tool bodies 204 of appropriate width according to different plastic film widths. This avoids irregular tool wear caused by mismatch between the tool and the plastic film width, extending tool life, reducing tool replacement frequency and cost. During the cutting process, the auxiliary lubrication component 3 and the liquid distribution component 4 work together to lubricate the tool body 204. In component 3, the built-in electrically operated liquid reservoir 301 at the upper end of the hollow chamber 300, located directly above the rotating spindle 201, outputs lubricating oil. The lubricating oil first enters the distribution groove 400 of the liquid equalization component 4, and then is evenly discharged through multiple one-way electrically operated drain valves 401 at the lower end of the distribution groove 400, dripping onto the sponge impregnation strip 304 inside the hollow chamber 300. Multiple springs 303 on the left and right inner walls of the hollow chamber 300 apply pressure to the sponge impregnation strip 304, causing the sponge impregnation strip 304 to come into close contact with the outer wall of the tool body 204 that passes through the silicone bottom sheet 302 at the lower end of the hollow chamber 300, thereby distributing the lubricating oil... The silicone base sheet 302, evenly coated on the blade body 204 directly below the cutter, also prevents lubricant leakage. As the blade body 204 slides up and down, the bottom blade body 204 performs the cutting operation, while the unused top blade body 204 can enter the auxiliary maintenance process. This not only improves the smoothness of subsequent cutting but also effectively reduces the wear rate of the blade body 204, further extending its lifespan. It also ensures the stability of cutting quality. The silicone base sheet 302 effectively prevents lubricant leakage, avoiding lubricant waste and pollution to the working environment, making it more energy-efficient and environmentally friendly.

[0034] Second implementation method:

[0035] Figures 6-7This invention discloses a cutting device for processing plastic film. The guide assembly 5 includes grooved guide strips 500 respectively formed on the feeding table panel 101 and the placing table panel 102. Limiting side strips 501 are symmetrically fixedly connected to the front and rear sides of the upper end of the feeding table panel 101 and the placing table panel 102. Electric push rods 502 are fixedly connected to the ends of the two corresponding limiting side strips 501 that are close to each other. DT series electric push rods can be selected. A linkage abutment side plate 503 is fixedly connected to the output end of the electric push rod 502. The linkage abutment side plate 503 and the corresponding grooved guide strips 500 are... The grooved guide strip 500 and the limiting side strip 501 form a mechanical guiding structure through a sliding connection between the 0 and 0. Together with the linkage abutment side plate 503 driven by the electric push rod 502, it achieves multi-dimensional constraint on the plastic film. As an independent accessory, this guide component 5 is particularly suitable for production lines that continuously process plastic films of various specifications. By controlling the electric push rod 502, precise guidance and constraint of plastic films of different specifications can be achieved. In automated production lines, it can work in coordination with equipment in other processes such as conveying and cutting, reducing manual intervention and improving the level of automation and overall production efficiency.
