Description

Technical Field

[0001] This utility model belongs to the field of polyurethane processing technology, and specifically relates to a cutting device for polyurethane processing. Background Technology

[0002] Polyurethane materials have a wide range of applications, including building insulation, sound insulation, waterproofing, and industrial manufacturing. In construction and industrial manufacturing, polyurethane materials often need to be customized in shape and size according to specific design requirements. Cutting allows polyurethane materials to be processed into shapes and sizes that meet design requirements and satisfy different usage needs. During construction, polyurethane materials may need to be cut into smaller pieces or sheets for easier handling and installation. Especially in large projects or complex structures, cutting polyurethane materials can significantly improve construction efficiency and reduce labor intensity. In some cases, multiple polyurethane components need to be spliced ​​together to form larger structures or components. Precise cutting ensures that the interfaces between components are flat and tight, achieving good splicing and connection effects. During manual cutting, differences in worker skill levels and operating habits can lead to inconsistencies in the size and shape of the cut products. This not only affects the aesthetics of the product but may also affect its performance and safety. Therefore, whether a cutting device can reduce the applied force, reduce direct contact, quickly position and cut, and reduce preparation and adjustment time is a technical problem that this utility model urgently needs to solve. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cutting device for polyurethane processing that can reduce the applied force, reduce direct contact, quickly position and cut, and reduce preparation and adjustment time.

[0004] This utility model discloses a cutting device for polyurethane processing, including a cutting table, a pressing component, and a cutting component, wherein the cutting component and the pressing component are respectively installed on the cutting table;

[0005] The pressing assembly includes a first support assembly, a roller, and a handle. The roller is rotatably mounted on the support assembly, and the handle is mounted on one side of the first support assembly.

[0006] The cutting assembly includes a second support assembly, a cutting blade, a pressure handle, and an elastic component. The pressure handle is mounted on the top of the cutting blade, the cutting blade is mounted through the second support assembly, and the elastic component connects the second support assembly and the cutting blade.

[0007] Furthermore, the first support assembly includes two first vertical rods symmetrically and parallelly installed on both sides of the cutting table; the upper part of the two first vertical rods is provided with a first through hole, and a first horizontal rod is rotatably installed through the two first through holes. One end of the first horizontal rod is provided with a positioning protrusion, and the handle is provided with a groove that matches the positioning protrusion. The positioning protrusion is inserted into the groove to install the handle onto the first horizontal rod.

[0008] Furthermore, two connecting rods are vertically mounted on the first crossbar, the two connecting rods are arranged parallel to each other, and the ends of the two connecting rods are respectively connected to the two ends of the roller.

[0009] Furthermore, the second support assembly includes two second vertical rods fixed to both sides of the cutting table, and a third horizontal rod vertically installed at the top of the two second vertical rods; the third horizontal rod has an elongated knife hole, and the two second vertical rods have vertically formed guide knife grooves on opposite sides.

[0010] Furthermore, the cutting blade includes a blade, a connecting block, and a lever plate connected sequentially from bottom to top. The two sides of the blade are embedded in two guide slots. The lever plate slides through the blade hole, and the top of the lever plate is connected to the pressure handle.

[0011] Furthermore, the elastic component includes a plurality of springs, the two ends of which are respectively connected to the connecting block and the third crossbar.

[0012] The beneficial effects of this utility model are as follows:

[0013] The guide groove can precisely guide the movement path of the cutting tool, ensuring straightness and parallelism during the cutting process, thereby avoiding cutting deviation;

[0014] The pressing component fits tightly against the surface of the polyurethane material, providing stable support and preventing the material from moving or deforming during cutting, thus further improving cutting accuracy. This high-precision cutting method is suitable for the production of products with strict requirements on size and shape.

[0015] Using this cutting device, workers only need to turn the handle downward to rotate the roller and press down on the pressure handle to start the cutting work, reducing the tedious preparation and adjustment time in traditional cutting methods.

[0016] During the cutting process, workers mainly operate the handle and pressure bar, reducing the chance of direct contact with the sharp cutting tool and lowering the risk of injury;

[0017] Due to its high cutting precision and stability, this cutting device can minimize waste generation and improve material utilization. Attached Figure Description

It should be understood that such terms can be used interchangeably where appropriate.

[0025] It should be noted that, in this application, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0026] like Figure 1-3 As shown, a cutting device for polyurethane processing includes a cutting table 1, a pressing component, and a cutting component, wherein the cutting component and the pressing component are respectively installed on the cutting table 1. After the polyurethane material is placed on the cutting table 1, the pressing component is used to press down the polyurethane material to prevent it from shifting; then the cutting component is used to cut the polyurethane material downwards.

[0027] The pressing assembly includes a first support assembly, a roller 2, and a handle 3. The roller 2 is rotatably mounted on the support assembly, and the handle 3 is mounted on one side of the first support assembly. The first support assembly includes two symmetrical and parallel first vertical rods 4 fixed to both sides of the cutting table 1. A first through hole 5 is provided at the upper part of the two first vertical rods 4, through which a first horizontal rod 6 is rotatably mounted. The contact point between the first horizontal rod 6 and the first through hole 5 of the two first vertical rods 4 can be rotatably connected by a bearing seat. A positioning protrusion 7 is provided at one end of the first horizontal rod 6, and a groove 8 matching the positioning protrusion 7 is provided on the handle 3. The positioning protrusion 7 is inserted into the groove 8 to install the handle 3 onto the first horizontal rod 6.

[0028] Two connecting rods 9 are vertically fixed on the first crossbar 6. The two connecting rods 9 are arranged parallel to each other, and the ends of the two connecting rods 9 are respectively connected to the two ends of the roller 2. When in use, first insert the groove 8 of the handle 3 into the positioning protrusion 7, and then rotate the handle 3 clockwise until the roller 2 contacts and presses against the upper surface of the polyurethane material; after cutting, rotate the handle 3 counterclockwise to make the roller 2 leave the polyurethane material.

[0029] The cutting assembly includes a second support assembly, a cutting blade 10, a pressure handle 11, and an elastic component 12. The pressure handle 11 is mounted on the top of the cutting blade 10, the cutting blade 10 is mounted through the second support assembly, and the elastic component 12 connects the second support assembly and the cutting blade 10.

[0030] The second support assembly includes two second vertical rods 13 fixed to both sides of the cutting table 1, and a third horizontal rod 14 vertically installed at the top of the two second vertical rods 13. The third horizontal rod 14 has elongated blade holes 15, and the two second vertical rods 13 have vertically formed guide grooves 16 on opposite sides. The cutting blade 10 includes a blade 17, a connecting block 18, and a lever plate 19 welded sequentially from bottom to top. The two sides of the blade 17 are embedded in the two guide grooves 16; the lever plate 19 slides through the blade holes 15, and its top end is connected to the pressure handle 11.

[0031] The elastic component 12 includes two springs, with their ends connected to the connecting block 18 and the third crossbar 14, respectively. When the polyurethane material is pressed using the pressing component, pressing the handle 11 with the palm facing down stretches the springs, generating an elastic deformation force. The cutting blade 10 moves downward, causing the blade 17 to cut the polyurethane material, thus achieving the cutting of the polyurethane. After cutting is completed, releasing the hand causes the springs to return to their original state, which in turn causes the cutting blade 10 to move upward.

[0032] It should be noted that in this embodiment, the width of the elongated knife hole 15 is smaller than the width of the pressure rod; the width of the lever plate 19 is slightly smaller than the width of the elongated knife hole 15, ensuring that the lever plate 19 can be placed through the knife hole 15; the width of the guide groove 16 is slightly larger than the thickness of the blade 17; and the two ends of the connecting block 18 are in contact with the surfaces of the two second vertical rods 13.

[0033] 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 way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
