Description

Technical Field

[0001] This invention relates to the field of PMI foam production technology, specifically a PMI foam cutting and dust removal device and method. Background Technology

[0002] Polymethacrylimide (PMI) foam is a lightweight, closed-cell rigid foam. During the production of PMI foam, it needs to be cut to the required size. Inevitably, debris will be generated during the cutting process. Due to the relatively high density of PMI foam, these debris particles are small. These debris particles are not only easy to be scattered into the air, but also easy to be inhaled by workers, causing health hazards. In addition, the small size of the debris particles makes them easy to adhere to the workbench. Currently, the debris generated during cutting is generally handled by workers using handheld vacuum cleaners or vacuum fans. However, handheld vacuum cleaners are inconvenient and increase the workload for workers. Vacuum fans can only clean one area at a time. In the process of cutting PMI foam, different shapes of PMI foam are often cut at different locations, so vacuum fans cannot meet the actual needs. To address these issues, we provide a PMI foam cutting dust removal device and method to solve the problems mentioned above. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-7 In this embodiment of the invention, a PMI foam cutting dust removal device includes a base frame 1. Slide rails 2 are fixedly connected to the upper ends of both sides of the base frame 1. A mounting plate 4 is provided between the two slide rails 2. Sliding seats 3, which are slidably connected to the slide rails 2, are fixedly connected to the four corners of the lower end face of the mounting plate 4. The mounting plate 4 is provided with a moving component for driving the mounting plate 4 to move along the slide rails 2. Limiters are installed at both ends of the slide rails 2. The moving component allows the mounting plate 4 to be moved during use, and the limiters prevent the sliding seats 3 from derailing.

[0025] Please see Figure 2 The moving component includes a helical rack 16, which is fixedly connected to one side of the base frame 1. A drive motor 5 is fixedly connected to one side of the upper surface of the mounting plate 4. A helical gear 17 is fixedly connected to the output end of the drive motor 5, and the helical gear 17 meshes with the helical rack 16. When it is necessary to move the mounting plate 4, the drive motor 5 drives the helical gear 17 to rotate. The rotation of the helical gear 17 cooperates with the helical rack 16, which enables the mounting plate 4 to move along the slide rail 2.

[0026] Please see Figure 1 and Figure 2A fixing plate 19 is fixedly connected to one side of the upper surface of the mounting plate 4. A sliding frame 12 is fixedly connected to the upper end of the fixing plate 19. A lifting block 25 is slidably connected to the sliding frame 12. A lifting assembly for driving the lifting block 25 to move up and down is provided inside the sliding frame 12. The lifting assembly includes a threaded rod 11, which is rotatably connected inside the sliding frame 12 and engages with the lifting block 25. A first motor 18 is installed at the upper end of the fixing plate 19, and the output end of the first motor 18 is fixedly connected to the lower end of the threaded rod 11. When it is necessary to raise or lower the lifting block 25, the first motor 18 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 causes the lifting block 25 to move along the sliding frame 12, thereby realizing the adjustment of the lifting block 25.

[0027] Please see Figures 3-6 A mounting frame 10 is fixedly connected to the lifting block 25. The mounting frame 10 is equipped with a dust removal component for cleaning debris generated during foam cutting. The dust removal component includes L-shaped sliders 27, which are slidably connected to both sides inside the mounting frame 10. The mounting frame 10 is equipped with a drive component for moving the two L-shaped sliders 27.

The threads at both ends of the bidirectional lead screw 8 are respectively connected to the L-shaped sliders 27. 7. Threaded connection: A third motor 22 is fixedly connected to the bottom of one side of the mounting frame 10. Synchronous pulleys 20 are installed on the connecting shaft end of one end of the bidirectional lead screw 8 and the output end of the third motor 22. A synchronous belt 9 is installed between the two synchronous pulleys 20. During operation, the third motor 22 drives the synchronous pulleys 20 to rotate. The rotation of the synchronous pulleys 20 drives the synchronous belt 9 to rotate. The rotation of the synchronous belt 9 drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 can drive the two L-shaped sliders 27 to move closer or further apart, thereby adjusting the position of the two dust collector hoods 13.

[0028] Please see Figure 3Each L-shaped slider 27 has a mounting shaft 36 rotatably connected to its lower end. A dust cover 13 is fixedly connected to the end of the mounting shaft 36 furthest from the lifting block 25. Each L-shaped slider 27 is equipped with an adjustment component for adjusting the angle of the dust cover 13. The adjustment component includes a second gear 24, which is mounted on the end of the mounting shaft 36 near the lifting block 25. A second motor 21 is fixedly connected to the lower end of one side of each L-shaped slider 27. A first gear 23 is mounted on the output end of the second motor 21, and the first gear 23 meshes with the second gear 24. During operation, the second motor 21 drives the first gear 23 to rotate, which in turn drives the second gear 24 to rotate. The second gear 24 then drives the mounting shaft 36 to rotate, which in turn rotates the dust cover 13, thereby adjusting the state of the dust cover 13.

[0029] Please see Figures 4-6 The mounting plate 4 is equipped with a suction assembly for providing negative pressure to the dust hood 13. The suction assembly includes a mounting box 7, which is mounted on the upper surface of the mounting plate 4. A three-way pipe 30 communicating with the interior of the mounting box 7 is fixedly connected to the upper end of the mounting box 7. Flexible hoses 15 are connected to both ends of the three-way pipe 30. A branch pipe 14 is connected to the end of each flexible hose 15 away from the three-way pipe 30. The branches of the branch pipes 14 are all connected to the dust hood 13. A collection chamber 26 is opened at the upper end of the mounting box 7. An installation channel 31 communicating with the bottom cavity of the mounting box 7 is opened in the middle of the lower end of the collection chamber 26. A fourth motor 33 is installed in the middle of the lower end of the mounting box 7. A blade 32 is installed at the output end of the fourth motor 33. The blade 32 is located inside the installation channel 31. Several strip holes 6 communicating with the bottom cavity of the mounting box 7 are opened at the lower end of the mounting box 7. A collection box 29 is slidably connected inside the collection chamber 26. The lower end face of the collection box 29 is provided with a filter screen. The mounting box 7 is fixedly connected to one end of the collection chamber 26 with a mounting arm 34. A magnet 35 is installed in the middle of the mounting arm 34. The collection box 29 is provided with an iron plate for cooperating with the mounting arm 34. A handle 28 is fixedly connected to the middle of the side of the collection box 29 away from the mounting arm 34. During operation, the fourth motor 33 drives the blade 32 to rotate. The high-speed rotation of the blade 32 drives the airflow, which generates negative pressure in the collection chamber 26. Since the hose 15 is connected to the three-way pipe 30, negative pressure is generated at the port of the branch pipe 14, which can achieve the suction of foam impurities. The sucked-in foam impurities will enter the collection box 29 for collection. When the collection box 29 is full, it can be pulled out by the handle 28, which makes it easy to clean the collection box 29. The magnet 35 can limit and fix the collection box 29 to prevent it from sliding out of the collection chamber 26.

[0030] The working principle of this invention is as follows: During operation, the state and position of the dust hood 13 are first adjusted according to the model of the PMI foam cutter, the size of the PMI foam, or the cutting position of the PMI foam. During adjustment, the second motor 21 drives the first gear 23 to rotate, the first gear 23 drives the second gear 24 to rotate, the second gear 24 drives the mounting shaft 36 to rotate, and the mounting shaft 36 rotates accordingly, thereby adjusting the state of the dust hood 13. The third motor 22 drives the synchronous pulley 20 to rotate, the synchronous pulley 20 drives the synchronous belt 9 to rotate, and the synchronous belt 9 drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 can drive the two L-shaped sliders 27 to move closer or further apart, thereby adjusting the position of the two dust collector hoods 13. The first motor 18 drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the lifting block 25 to move along the sliding frame 12, thereby adjusting the lifting of the lifting block 25. During dust removal, the fourth motor 33 drives the blades 32 to rotate. The high-speed rotation of the blades 32 drives the airflow, creating a negative pressure in the collection chamber 26. Since the hose 15 is connected to the three-way pipe 30, negative pressure is generated at the ports of the branch pipe 14, thereby enabling the suction of foam impurities. The sucked-in foam impurities will enter the collection box 29 for collection.
