Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyurethane board production technology, and in particular to a fixed-distance slitting device for polyurethane board production. Background Technology
[0002] In the production of polyurethane boards in the decoration industry, the fixed-distance slitting process is crucial to the quality of the boards and their subsequent applications. Traditional fixed-distance slitting devices, if they lack efficient cutting and a collaborative design for cleaning throughout the entire process, are prone to many problems.
[0003] Traditional fixed-distance slitting devices do not employ targeted cutting optimization schemes. During the cutting process, the surface of the board may produce defects such as burrs and skewed cuts due to uneven force or insufficient stability of the cutting tool, which affects the dimensional accuracy and appearance quality of the board.
[0004] If impurities on the board surface are not effectively cleaned before and after cutting, dust, oil and other contaminants attached to the board surface are easily mixed into the cut during the cutting process, resulting in impurity residue or localized strength reduction at the cut, which in turn affects the splicing accuracy and overall structural stability of the board during decoration.
[0005] In addition, if the debris generated during the cutting process is not removed in time, it will not only accumulate on the worktable of the equipment, interfering with the positioning and conveying of subsequent boards, but may also re-adhere to the surface of the boards due to the vibration of the equipment during operation, causing secondary pollution.
[0006] If there is a lack of effective cleaning measures for the underside of the board, the debris generated by the contact between the board and the conveyor belt during cutting or the dust attracted by static electricity will be difficult to remove. This will easily cause scratches or contamination on the board surface during subsequent stacking and transportation, increasing the cost of subsequent quality inspection and rework.
[0007] The aforementioned problems result in shortcomings in traditional slitting equipment in terms of production efficiency, product quality, and cleanliness and environmental protection, making it difficult to meet the decoration industry's demand for high precision and high cleanliness of polyurethane boards.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequential relationship of the indicated technical features.
[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] Please see Figure 1-4 This utility model provides a technical solution: a fixed-distance slitting device for polyurethane board production, including a base 1, a conveyor belt 7 rotatably mounted on the base 1, a board 6 placed on the conveyor belt 7, and a cleaning device and a cutting device respectively provided at the front and rear ends of the board 6.
[0034] The cleaning device includes: a roller brush 2, a slider 3, a guide rail 4, and a spring 5;
[0035] Two roller brushes 2 are arranged in parallel on the base 1. The lower roller brush 2 is rotatably connected to the base 1, and the upper roller brush 2 is rotatably connected to the slider 3. The slider 3 is slidably connected in the guide rail groove 4. The two ends of the spring 5 are respectively fixedly connected to the upper part of the slider 3 and the guide rail groove 4.
[0036] The upper roller brush 2 can adapt to the thickness of the plate 6. When the plate 6 passes through the roller brush 2, it presses the roller brush 2 upward, so that the slider 3 moves upward in the guide groove 4, and the spring 5 is compressed, thereby adjusting the distance between the two roller brushes 2 and ensuring that they are always in close contact with the plate 6.
[0037] The cutting device includes: bracket 8, lead screw 9, chain 10, drive sprocket 11, high-speed motor 12, vacuum cleaner 13, vacuum hose 14, sliding part 15, circular saw 16, rotating shaft 17, stepper motor 18, synchronous pulley 19, belt 20, roller conveyor 21, driven sprocket 22;
[0038] The bracket 8 is fixedly installed on the base 1, and both lead screws 9 are rotatably connected to the bracket 8. The stepper motor 18 is fixedly installed on the bracket 8.
[0039] Three synchronous pulleys 19 are respectively fixedly mounted on two lead screws 9 and the output shaft of stepper motor 18, and are arranged in a triangular configuration by meshing with belt 20;
[0040] The sliding member 15 is threadedly connected to the two lead screws 9, and the high-speed motor 12 and the suction pipe 14 are both fixedly installed on the sliding member 15;
[0041] The drive sprocket 11 and the suction pipe 14 are fixedly connected to the high-speed motor 12 and the vacuum cleaner 13 respectively. The rotating shaft 17 is rotatably mounted on the sliding part 15. The circular saw 16 and the driven sprocket 22 are fixedly mounted at both ends of the rotating shaft 17 respectively. The drive sprocket 11 and the driven sprocket 22 mesh with each other through the chain 10. The roller conveyor 21 is rotatably mounted on the base 1.
[0042] When the stepper motor 18 is started, the synchronous pulley 19 fixed on the output shaft of the stepper motor 18 drives the other two synchronous pulleys 19 to rotate synchronously through the belt 20, thereby driving the two lead screws 9 to rotate synchronously, controlling the forward and reverse rotation of the stepper motor 18, and the sliding member 15 can move left and right on the lead screw 9.
[0043] Start the high-speed motor 12. The output shaft of the high-speed motor 12 drives the drive sprocket 11, which drives the driven sprocket 22 to rotate at high speed through the chain 10. The driven sprocket 22 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the circular saw 16 to rotate to cut the board 6. The vacuum cleaner 13 cleans the debris cut off in real time through the vacuum pipe 14. The rollers on the roller conveyor 21 are equipped with brushes to clean the lower surface of the board 6.
[0044] The principle and structure of conveyor belt 7 and roller conveyor 21 are similar to existing conveying equipment and are well known to those skilled in the art, so their internal structure will not be described in detail.
[0045] Working principle: When in use, the staff pushes the board 6 into the cleaning device for pre-cleaning, and then conveys it to the cutting device via the conveyor belt 7 for cutting. During the cutting process, the upper and lower surfaces of the board 6 can be cleaned by the vacuum cleaner 13 and the roller conveyor 21 to avoid unstable stacking and scratching of the board 6.
[0046] The cutting device uses a circular saw to cut 6 plates, and features a multi-stage cleaning design before, during and after cutting, which has significant advantages.
[0047] The adaptive roller brush 2 before cutting can dynamically adjust the contact force according to the surface of the board 6, effectively removing dust, oil and other impurities attached to the surface of the board 6, avoiding impurities from affecting the stability and accuracy of the circular saw 16 during cutting, and laying a clean foundation for subsequent cutting processes.
[0048] During the cutting process, the vacuum cleaner 13 absorbs the debris generated on the surface of the board 6 in real time, which can quickly remove the waste generated at the moment of cutting, prevent the debris from accumulating on the cutting path and interfering with the running trajectory of the circular saw 16, while reducing the spread of dust in the workshop, improving the working environment and reducing equipment maintenance costs.
[0049] After cutting, the brush-brushed roller conveyor 21 conveys the board 6. Its bristles can penetrate deep into the gaps on the lower surface of the board 6 to thoroughly clean up the small debris that fell and adhered during the cutting process due to vibration. This ensures that there are no residual impurities on the upper and lower surfaces of the board 6. This not only provides a clean product condition for subsequent quality inspection, stacking, and transportation processes, but also avoids problems such as scratches and contamination on the surface of the board 6 caused by debris residue. It ensures the appearance quality and installation accuracy of the polyurethane board 6 when used in decoration. The whole process cleaning design is interconnected, which significantly improves production efficiency and product quality, and meets the high requirements of the decoration industry for the cleanliness and processing accuracy of the board 6.
[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
