Technical Field

[0001] This invention relates to the field of polyurethane foam board cutting machine technology, and in particular to a self-cleaning reciprocating cutting device for polyurethane foam boards and its operating method. Background Technology

[0002] Polyurethane foam is a high-molecular polymer made primarily from isocyanate and polyether, mixed with various additives such as foaming agents, catalysts, and flame retardants using specialized equipment, and then foamed on-site through high-pressure spraying. Polyurethane foam comes in two types: flexible and rigid. The produced polyurethane foam is in a single block and requires cutting and other processes. A polyurethane foam board cutting machine is needed for cutting polyurethane foam, but existing polyurethane foam board cutting machines still have some problems.

[0003] Existing polyurethane foam board cutting machines generate debris in the interlayer during cutting. This debris can be ejected during transport and subsequent processing, affecting the working environment and requiring further cleaning of the debris, which is time-consuming and labor-intensive. To address this issue, we propose a self-cleaning reciprocating cutting device and operating method for polyurethane foam boards. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides a self-cleaning polyurethane foam board reciprocating cutting device and operating method. By setting two cutting saws at the front and back, cutting can be performed in both directions. Two support heads support the interlayer of the cut. The first roller brush and the second roller brush sweep the debris towards the air inlet. The debris in the interlayer can be sucked away in both directions, eliminating the need for subsequent dust removal and greatly improving work efficiency.

However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example:

[0021] like Figures 1-3 As shown, a self-cleaning polyurethane foam board reciprocating cutting device includes a cutting machine 1, a foam board 2 is provided at the top of the cutting machine 1, a movable robotic arm 4 is provided at the top of the cutting machine 1, a fixed clamping plate 5 is provided on the front surface of the movable robotic arm 4, a support head 6 is provided at both ends of the fixed clamping plate 5, a first roller brush 7 is rotatably connected to the rear surface of the fixed clamping plate 5, an exhaust pipe 11 is provided on one side of the first roller brush 7, a second roller brush 8 is provided on one side of the exhaust pipe 11, an air inlet 9 is opened in the middle of the exhaust pipe 11, an arc plate 10 is provided at the bottom end of the inner wall of the air inlet 9, and a cutting saw 3 is provided on the front surface of the movable robotic arm 4. An inner groove is formed on the inner side of the fixed clamping plate 5. A first servo motor 12 is fixedly connected to the inner side of the inner groove. A fourth gear 16 is fixedly connected to the output end of the first servo motor 12. A fifth gear 17 is meshed with one side of the fourth gear 16. A sixth gear 18 is meshed with one side of the fifth gear 17. The rear surface of the sixth gear 18 is fixedly connected to the second roller brush 8. A third gear 15 is meshed with the other side of the fourth gear 16. A second gear 14 is meshed with one side of the third gear 15. A first gear 13 is meshed with one side of the second gear 14. The rear surface of the first gear 13 is fixedly connected to the first roller brush 7.

[0022] Existing polyurethane foam board cutting machines generate debris in the interlayer during cutting. This debris can spray out during transport and subsequent processing, affecting the working environment and requiring further cleaning, which is time-consuming and labor-intensive. By incorporating a first roller brush 7, after the cutting saw 3 cuts the foam board 2, the support head 6 enters along with the cut of the foam board 2, and the support head 6 opens the cut of the foam board 2. Figure 3 As shown, the first servo motor 12 is started simultaneously. The first servo motor 12 drives the fourth gear 16 to rotate clockwise. The fourth gear 16 drives the third gear 15 to rotate. The third gear 15 drives the second gear 14 to rotate. The second gear 14 drives the first gear 13 to rotate. At this time, the first gear 13 and the fourth gear 16 rotate in opposite directions. The fourth gear 16 drives the fifth gear 17 to rotate. The fifth gear 17 drives the sixth gear 18 to rotate. At this time, the sixth gear 18 and the fourth gear 16 rotate in the same direction. This causes the first roller brush 7 to rotate counterclockwise and the second roller brush 8 to rotate clockwise, sweeping the debris stuck on the inner wall of the cut towards the air inlet 9. The exhaust fan starts, causing the air pressure inside the exhaust pipe 11 to decrease, forming a pressure difference with the normal atmospheric pressure outside. The force difference generates a strong airflow, creating suction that draws debris near the air inlet 9 into the exhaust pipe 11. The curved plate 10, during its forward movement, closely adheres to the bottom surface of the cut in the foam board 2, scraping away debris tightly stuck to the cut surface. This debris is then drawn into the exhaust pipe 11 through the air inlet 9. After the first cut, the front cutting saw 3 is stopped, and the rear cutting saw 3 is used to cut the second layer of the foam board 2, completing the operation. With two cutting saws 3, cutting can be performed in both directions. Two support heads 6 support the cut layer, and the first roller brush 7 and the second roller brush 8 sweep debris towards the air inlet 9. This allows for the removal of debris from the layer in both directions, eliminating the need for subsequent dust removal and significantly improving work efficiency.

[0023] In other embodiments, this embodiment discloses, please refer to Figure 1 and Figure 4 As shown, the top of the cutting machine 1 is provided with a slide groove 19, the inner side of the slide groove 19 is provided with a baffle 20, one side of the baffle 20 is provided with a toothed groove, one side of the baffle 20 is meshed with a seventh gear 21, the front surface of the seventh gear 21 is fixedly connected with a worm gear 22, one side of the worm gear 22 is meshed with a worm 23, the inner side of the slide groove 19 is fixedly connected with a second servo motor 24, and the output end of the second servo motor 24 is fixedly connected to the bottom end of the worm 23.

[0024] As the number of cutting layers decreases, the second servo motor 24 starts, driving the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 22 to rotate, and the worm wheel 22 drives the seventh gear 21 to rotate. The seventh gear 21 pushes the baffle 20 to slide downward inside the slide groove 19. By setting the baffle 20 to block the foam board 2 when cutting, and its height is slightly lower than the cutting edge of the foam board 2, sufficient support is given to the foam board 2, so that the end cut of the foam board 2 will not be crooked. The two baffles 20 ensure that the cutting can be done back and forth.

[0025] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, there are two baffles 20 in total; by setting two baffles 20, the foam board 2 can be blocked during the back-and-forth cutting.

[0026] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, there are two cutting saws 3 in total; by setting there are two cutting saws 3 in total, the foam board 2 can be cut in both directions without any empty return, which greatly improves work efficiency.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
