[0002] With increasingly stringent requirements for building energy conservation, wall insulation materials are being used more and more widely. These materials not only possess excellent thermal insulation properties but also effectively reduce building energy consumption and improve living comfort. However, on construction sites, these insulation materials typically need to be cut to meet different size and shape requirements. During the cutting process, due to the physical properties of the materials, a large amount of dust is generated. This dust not only poses a serious threat to the health of construction workers, potentially causing respiratory and skin diseases, but may also pollute the surrounding environment, affecting the hygiene of the construction site. Therefore, we propose a dust-proof cutting device for wall insulation materials. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a dustproof cutting device for wall insulation materials, including an operating table 1, a drive motor 11 fixedly installed at the lower end of the operating table 1, a cutting blade 12 fixedly installed at the outer end of the drive motor 11 through its output shaft, a first dust cover 2 fixedly installed at the lower end of the operating table 1, a second dust cover 21 slidably installed on the upper side of the operating table 1, the cutting blade 12 is disposed inside the first dust cover 2 and the second dust cover 21, a dust guide sleeve 26 connected to its inner cavity is fixedly installed at the outer end of the first dust cover 2, a threaded pipe 22 is fixedly installed at the lower end of the second dust cover 21, the threaded pipe 22 is connected to the inner cavity of the second dust cover 21, a threaded sleeve 27 threadedly connected to the threaded pipe 22 is rotatably installed between the operating table 1 and the dust guide sleeve 26, the threaded sleeve 27 is connected to the inner cavity of the dust guide sleeve 26, and an outer pipe 28 is fixedly installed at the outer end of the dust guide sleeve 26.

[0026] Working principle: A drive motor 11 is set up, which can cut the wall insulation material through its output shaft and cutting blade 12;

[0027] During the cutting process, the threaded sleeve 27 is rotated, and through the threaded connection between it and the threaded tube 22, the second dust cover 21 can be driven to move downward, so that the lower end of the second dust cover 21 contacts the upper end of the wall insulation material, and through the contact between the lower end of the wall insulation material and the upper end of the operating table 1, the dust generated by the cutting blade 12 is retained in the first dust cover 2 and the second dust cover 21.

[0028] Then connect the external pipe 28 to the external air pump, start the external air pump, and with the air guide holes on the surface of the first dust cover 2 and the second dust cover 21, the air inside the first dust cover 2 and the second dust cover 21 can be guided into the dust guide sleeve 26 to achieve the effect of guiding dust.

[0029] As a further description of the above technical solution: A connecting plate 20 is fixedly installed on the outer end of the second dust cover 21, and a conduit 25 is fixedly installed between the connecting plate 20 and the second dust cover 21. The two ends of the conduit 25 are respectively connected to the inner cavity of the second dust cover 21 and the threaded tube 22; a limit plate 24 is fixedly installed on the upper end of the operating table 1, and a limit slot 23 is opened on the outer side of the connecting plate 20. The limit slot 23 and the limit plate 24 are inserted into each other.

[0030] Specifically, a connecting plate 20 is provided, and the movement direction of the second dust cover 21 can be restricted through the plug-in connection between the limiting insert plate 24 and the limiting slot 23, so that the rotating threaded sleeve 27 can drive the second dust cover 21 to move up and down through the threaded connection between it and the threaded tube 22.

[0031] A conduit 25 is provided, through a threaded tube 22 and a threaded sleeve 27, to guide dust inside the second dust cover 21 into the dust guide sleeve 26.

[0032] As a further description of the above technical solution: A first through hole 29 is provided at the upper end of the dust guide sleeve 26, which communicates with the threaded sleeve 27. A movable tube 3 is inserted into the dust guide sleeve 26, and a second through hole 36 is provided around the movable tube 3, with the second through hole 36 aligned with the outer tube 28. A limiting ring 31 that fits against the movable tube 3 is fixedly installed on the inner wall of the dust guide sleeve 26. A limiting rail 33 is provided on the inner wall of the dust guide sleeve 26, and a limiting strip 32 that inserts into the limiting rail 33 is fixedly installed around the movable tube 3. The outer end of the dust cover 26 has a threaded hole 34, and the outer end of the movable tube 3 is rotatably mounted with a threaded plate 35 that is threadedly connected to the threaded hole 34. A dust collection sleeve 4 is inserted into the movable tube 3, and a filter screen 41 is inserted into the rear side of the inner cavity of the dust collection sleeve 4. A sealing ring 42 is fixedly installed on the inner wall of the front side of the dust collection sleeve 4. A sealing plate 43 is provided on the rear side of the sealing ring 42. The outer periphery of the sealing plate 43 is in clearance fit with the inner wall of the dust collection sleeve 4. A limit rod 45 is fixedly installed at the front end of the sealing plate 43. A spring 47 is fixedly installed between the limit rod 45 and the sealing ring 42.

[0033] Specifically, when installing the filter screen 41, it is inserted into the dust collection sleeve 4, and then the dust collection sleeve 4 is inserted into the movable tube 3. Subsequently, the movable tube 3 can be installed into the dust guide sleeve 26 through the insertion connection between the limiting insert rail 33 and the limiting insert strip 32. When the threaded plate 35 contacts the threaded hole 34, the threaded plate 35 is rotated. Through the threaded connection between it and the threaded hole 34, the movable tube 3 can be positioned, and the second through hole 36 can be aligned with the position of the outer tube 28.

[0034] When the external air pump guides the dust through the external pipe 28, the flowing air pushes the sealing plate 43, causing the sealing plate 43 and the sealing ring 42 to separate. This allows air to enter the dust collection sleeve 4 through the gap between them. The dust then passes through the internal filter screen 41 of the dust collection sleeve 4, which blocks the dust in the air and traps it inside the dust collection sleeve 4. When the external air pump is turned off, the airflow stops, and the spring 47 returns to its original deformation, causing the sealing plate 43 and the sealing ring 42 to come into contact with each other, achieving a sealing effect on the front end of the dust collection sleeve 4. This confines the dust inside the dust collection sleeve 4. The dust can be recovered by disassembling the dust collection sleeve 4 and the filter screen 41.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
