Technical Field

[0001] This utility model belongs to the field of cutting equipment, and in particular relates to a plastic cutting machine that prevents deviation. Background Technology

[0002] Plastic cutting machines are specialized equipment for the precise cutting and molding of plastic materials (such as PE, PP, PVC, ABS, nylon, etc.). Their core function is to cut plastic raw materials (sheets, pipes, profiles, films, etc.) to preset sizes and shapes, providing qualified blanks or finished products for subsequent production (such as assembly, injection molding, packaging). They are widely used in plastic processing, building materials, electronics, automotive, packaging and other industries.

[0003] In the existing technology, plastic sheet cutting is mainly done by saw blades. Such plastic cutting machines mainly include a frame and a worktable set on the top of the frame. The saw blade can extend out of the worktable, and a pressure plate device is set on the worktable. With the above settings, the plastic can be cut.

[0004] However, during the cutting process, the saw blade generates a certain amount of heat (friction heat). The cutting heat softens the material locally, causes uneven resistance of the tool, and leads to lateral displacement, which in turn causes problems with the cutting quality. Utility Model Content

[0005] This invention addresses the technical problems existing in current plastic cutting machines by proposing a plastic cutting machine that is reasonably designed, simple in structure, easy to process, and can effectively reduce the probability of deviation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a plastic cutting machine to prevent deviation, including a frame and a worktable set on the top of the frame. A saw blade is set on the frame, and the saw blade is liftably mounted on the frame and can extend out of the worktable. The saw blade is slidably mounted on the frame. A guide groove is provided on the worktable, and the saw blade extends out of the worktable through the guide groove. A pressure plate mechanism is also provided on the worktable. The pressure plate mechanism includes a connecting plate set on the side of the guide groove and lifting cylinders set at both ends of the connecting plate.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, such as Figures 1-5As shown, this embodiment aims to solve the problem of misalignment that occurs when existing plastic cutting machines cut sheet-like plastics. Considering that there are two main causes of misalignment—one is the problem caused by cutting heat, and the other is the problem of unstable fixing—this embodiment provides a plastic cutting machine to prevent misalignment, including a frame 1 and a worktable 2 set on top of the frame 1. In this embodiment, the frame 1 is arranged in a cuboid frame shape, with a top plate (i.e., the worktable 2) on top. A shelf 11 is arranged inside the frame 1, dividing the interior of the frame 1 into upper and lower sections. Two rows of tracks are laid on the shelf 11, and sliders are installed on the tracks. Mounted on a sliding plate 12, guide shafts are located at the four corners of the sliding plate 12. A height adjustment cylinder 17 is located at the center of the sliding plate 12, and a motor mounting plate 13 is located at the power end of the height adjustment cylinder 17. Linear bearings are located at the four corners of the motor mounting plate 13, through which the guide shafts pass. A drive motor is located on the motor mounting plate 13, and a saw blade 14 is mounted at the power end of the drive motor. Thus, the saw blade 14 can be raised and lowered on the frame 1, and can also extend out of the worktable 2. The saw blade 14 is slidably mounted on the frame 1, and a guide groove 21 is provided on the worktable 2 through which the saw blade 14 extends out. This ensures that the saw blade 14 remains below the worktable 2 during use, guaranteeing safety.

[0018] A traction timing belt 16 is connected to both ends of the sliding plate 12, and a timing wheel is provided at both ends of the shelf plate 11. At the same time, a sliding motor 15 is provided below the shelf plate 11. The timing wheel has a double wheel structure, one of which is connected to the sliding motor 15, and the other is fitted with the traction timing belt 16. In this way, the saw blade 14 can move along the guide groove 21.

[0019] To ensure stability during cutting, a pressure plate mechanism 3 is also provided on the worktable 2. The pressure plate mechanism 3 includes a connecting plate 31 located on the side of the guide groove 21 and lifting cylinders 32 located at both ends of the connecting plate 31. A pressure plate 33 is provided at the bottom of the connecting plate 31, thus pressing down the plastic sheet to be cut. To prevent the plastic sheet to be cut from moving left and right, two guide limiting plates 22 are also provided on the worktable 2. They are located on both sides of the plastic sheet to be cut and are made of polished metal plates to reduce friction with the plastic sheet. At the same time, an auxiliary pressure plate mechanism 7 is also provided on the worktable 2, which is located away from the guide groove 21. This forms a multi-point fixation to ensure stability. In this embodiment, the auxiliary pressure plate mechanism 7 also includes a connecting plate, lifting cylinders, and a pressure plate.

[0020] Unlike the pressure plate 33 of the auxiliary pressure plate mechanism 7, the pressure plate 33 of the pressure plate mechanism 3, in addition to its stabilizing function, also needs to cool down the blade. Therefore, a suction groove 331 is provided on the side of the pressure plate 33 near the guide groove 21, and an exhaust pipe 332 is installed on the pressure plate 33. Simultaneously, an exhaust hood 4 is installed below the saw blade 14, covering the lower middle part of the saw blade 14. An auxiliary exhaust pipe 41 is installed at the bottom of the exhaust hood 4. Since the saw blade 14 needs to move, the auxiliary exhaust pipe 41 is a telescopic pipe. Both the exhaust pipe 332 and the auxiliary exhaust pipe 41 are connected to a gas collection box 5. A fan 62 is connected to the end of the gas collection box 5 furthest from the exhaust pipe 332 and the auxiliary exhaust pipe 41. In this way, by drawing air, the airflow is driven, thereby achieving the purpose of cooling. At the same time, it also sucks away the cutting debris, preventing dust from splashing.

[0021] Considering that cutting will generate a large amount of plastic debris, a filter box 6 is also provided between the fan 62 and the air collection box 5 to collect these debris. The filter box 6 is located on one side of the frame 1, and the fan 62 is located at one end of the filter box 6. The air collection box 5 is connected to the end of the filter box 6 away from the fan 62.

[0022] In order to achieve effective filtration, in this embodiment, the filter box 6 includes a box body 61 with an opening on the side of the box body 61 away from the frame 1. A sealing plate 66 for closing the opening is provided on the box body 61. In this embodiment, one side of the sealing plate 66 is connected to the box body 61 by a hinge, and the other end is fixed by a latch.

[0023] In the housing 61, from the air collection box 5 towards the fan 62, there are arranged a filter cotton box 63, an activated carbon box 64, and a HEPA high-efficiency filter box 65, all of which can be inserted and removed into the housing 61. Specifically, U-shaped slots are installed at the top and bottom of the housing 61, and corresponding protrusions are provided at the top and bottom of the filter cotton box 63, activated carbon box 64, and HEPA high-efficiency filter box 65 for insertion, facilitating the replacement or cleaning of the consumables inside. Among them, the filter cotton box 63 is used to remove large debris, the activated carbon box 64 is used to absorb odors and some small debris, and the HEPA high-efficiency filter box 65 is used to further remove odors and debris, ensuring that the air discharged from the fan 62 is clean.

[0024] Considering the large amount of debris generated during the cutting process, which easily clogs the filter cotton, this embodiment includes a frame-shaped insertion frame 631 to delay filter cotton replacement or cleaning. A layer of baffles 632 is located within the insertion frame 631, positioned in the center. This layer comprises several spaced-apart baffle groups, each group consisting of two baffles 632 arranged at an obtuse angle, spaced apart. This creates gaps between the baffles and between groups of baffles 632, ensuring airflow while blocking some debris and preventing rapid clogging of the filter cotton. Additionally, filter cotton 633 is also installed within the insertion frame 631, positioned close to the activated carbon box 64.

[0025] To prevent debris from falling into the housing 61 during connection, a blocking plate 634 is installed inside the connection bracket 631. The blocking plate 634 is located at the end of the housing 61 furthest from the filter plate, and its height is less than one-quarter of the height of the connection bracket 631. This ensures debris collection without affecting airflow.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
