Abstract
Description
Technical Field
[0001] This utility model relates to the field of blade cleaning technology, and in particular to an automatic cleaning device for blades of PVC profile cutting machines. Background Technology
[0002] In construction engineering, PVC profiles are a common decorative accessory. After the PVC profiles are extruded, workers need to cut the long strips of PVC profiles into sections according to the actual decoration requirements.
[0003] A cutting machine is a common cutting device. To facilitate cutting PVC profiles, the blade is usually heated during the cutting process. Due to the heating of the blade and the repeated contact between the blade and the PVC profile, a paste can form on the blade surface. As the paste gradually accumulates on the blade surface, it can easily cause deformation of the PVC profile during cutting and result in burrs on the cut surface. Therefore, to improve the cutting effect of PVC profiles, the blade surface needs to be cleaned regularly.
[0004] The traditional cleaning method involves workers manually scraping off the paste from top to bottom on the blade surface using a scraper. However, this manual cleaning method is not only labor-intensive but also poses a safety hazard due to the risk of hand injuries from careless operation. Utility Model Content
[0005] In view of the above problems, this utility model provides an automatic cleaning device for the blades of a PVC profile cutting machine.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] Furthermore, the scraper includes a scraper blade that is radially slidably connected to the mounting rod along the mounting rod. The mounting rod is provided with an elastic element for driving the scraper blade to move away from the mounting rod.
[0009] Furthermore, multiple scraper components are spaced apart along the circumference of the mounting rod, and the mounting rod is rotatably mounted within the mounting frame, which is equipped with limiters to restrict the rotation of the mounting rod.
[0010] Furthermore, the limiting component includes a limiting bolt. The outer wall of the rotating shaft of the mounting rod is provided with multiple threaded holes that correspond one-to-one with the scraper. The mounting frame is provided with a limiting hole for the limiting bolt to pass through. After the limiting bolt passes through the limiting hole, it is threaded into the threaded hole.
[0011] Furthermore, the cleaning component includes multiple nozzles for spraying cleaning fluid onto the blade surface. The multiple nozzles are arranged on the side of the mounting bracket near the blade, and one end of each nozzle is connected to a supply tank for supplying cleaning fluid.
[0012] Furthermore, a rotating frame is rotatably mounted on the support, the rotating frame is equipped with a cleaning brush, and a third driving member is provided on the support to drive the rotating frame to rotate so that the cleaning brush contacts the blade surface.
[0013] The beneficial effects of this utility model are as follows: the movable mounting frame allows the scraper to contact the blade surface, and then the vertically lowered bracket allows the scraper to scrape off the paste from the blade surface; by moving the mounting frame and the bracket together, the scraper can scrape off the paste from the blade surface multiple times from top to bottom; after scraping is completed, the cleaning component can further clean the residue on the blade surface, which has the effect of reducing the labor intensity of workers and improving work safety.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0019] This application discloses an automatic cleaning device for the blades of a PVC profile cutting machine, referring to... Figure 1 , Figure 2 and Figure 3 It includes two mounting brackets 1 respectively disposed on both sides of the blade 40. A support 2 is vertically slidably mounted on the mounting bracket 1, and a mounting frame 3 is horizontally slidably mounted on the support 2. A mounting rod 4 is mounted on the mounting frame 3, and a scraper 5 for scraping the paste on the blade 40 is mounted on the mounting rod 4. A first driving component 6 is provided on the mounting bracket 1 for driving the support 2 to move, and a second driving component 7 is provided on the support 2 for driving the mounting frame 3 to move. A cleaning component 9 is also provided on the support 2.
[0020] In this embodiment, the movable mounting frame 3 allows the scraper 5 to contact the surface of the blade 40. Then, the vertically downward movement of the bracket 2 allows the scraper 5 to scrape off the paste from the surface of the blade 40. Through the coordinated movement of the mounting frame 3 and the bracket 2, the scraper 5 can scrape off the paste from the surface of the blade 40 multiple times from top to bottom. After scraping is complete, the cleaning component 9 can further clean the residual material on the surface of the blade 40. This application provides an automatic cleaning device for the blade 40 of a PVC profile cutting machine, eliminating the need for manual cleaning of the paste adhering to the blade 40, thus reducing labor intensity and improving work safety.
[0021] Specifically, the first driving component 6 is an electric push rod, and the second driving component 7 is a linear lead screw module.
[0022] Specifically, the scraper 5 includes a scraper blade 51, which is radially slidably connected to the mounting rod 4. The mounting rod 4 is provided with an elastic element 42 for driving the scraper blade 51 to move away from the mounting rod 4.
[0023] In this embodiment, a sliding rod 41 is welded radially onto the mounting rod 4, and a baffle 411 is bolted to the end of the sliding rod 41 away from the mounting rod 4. A scraper blade 51 is slidably connected to the sliding rod 41, and a notch 511 for accommodating the baffle 411 is provided on the scraper blade 51. An elastic element 42 includes a spring, which is sleeved on the outside of the sliding rod 41, with both ends of the spring abutting against the mounting rod 4 and the scraper blade 51, respectively. During the scraping process, the elastic element 42 ensures that the paste on the cutter surface and at the blade edge can be scraped off by the scraper blade 51.
[0024] Furthermore, multiple scraper components 5 are spaced apart along the circumference of the mounting rod 4. The mounting rod 4 is rotatably mounted inside the mounting frame 3, and the mounting frame 3 is provided with a limiting component to restrict the rotation of the mounting rod 4.
[0025] In this embodiment, the operator can periodically rotate the mounting rod 4 to switch to a new scraper 5. Furthermore, since the baffle 411 is bolted to the slide rod 41, the operator can remove the baffle 411 during the switching process to disassemble and clean the used scraper blade 51.
[0026] Specifically, the limiting component includes a limiting bolt 8. The outer wall of the rotating shaft of the mounting rod 4 is provided with multiple threaded holes 43 that correspond one-to-one with the scraper 5 along its own circumference. The mounting frame 3 is provided with a limiting hole for the limiting bolt 8 to pass through. After the limiting bolt 8 passes through the limiting hole, it is threaded into the threaded hole 43.
[0027] In this embodiment, after the mounting rod 4 rotates to switch the scraper 5, the limiting bolt 8 can be passed through the limiting hole and threaded into the corresponding threaded hole 43 to restrict the rotation of the mounting rod 4.
[0028] Specifically, the cleaning component 9 includes multiple nozzles 91 for spraying cleaning fluid onto the surface of the blade 40. The multiple nozzles 91 are arranged on the side of the mounting bracket 1 near the blade 40, and one end of each nozzle 91 is externally connected to a supply tank (not shown in the figure) for supplying cleaning fluid.
[0029] In this embodiment, a flexible water pipe connects the nozzle 91 to the supply box, and a water pump for transporting cleaning fluid is installed inside the supply box. After scraping is completed, the mounting frame 3 is moved to move the scraper 5 away from the blade 40, and then cleaning fluid can be sprayed onto the surface of the cutter through the nozzle 91, thereby improving the cleaning effect on the surface of the blade 40.
[0030] Furthermore, a rotating frame 10 is rotatably mounted on the support 2, a cleaning brush 20 is mounted on the rotating frame 10, and a third driving member 30 is provided on the support 2 to drive the rotating frame 10 to rotate so that the cleaning brush 20 contacts the surface of the blade 40.
[0031] In this embodiment, after the nozzle 91 sprays cleaning fluid onto the surface of the blade 40, the rotating frame 10 is rotated to bring the cleaning brush 20 into contact with the surface of the blade 40. Subsequently, the support 2 moves downward to brush away any residue on the surface of the blade 40. By moving the support 2 in conjunction with the rotating rod, the surface of the blade 40 can be cleaned multiple times, which has the benefit of improving the cleaning effect of the blade 40.
[0032] Specifically, the third driving component 30 is a driving cylinder, one end of which is rotatably connected to the bracket 2, and the piston rod of the driving cylinder is rotatably connected to the movable end of the rotating frame 10.
[0033] The implementation principle of an automatic cleaning device for PVC profile cutting machine blades according to an embodiment of this application is as follows: Moving the mounting frame 3 allows the scraper 5 to contact the surface of the blade 40. Then, the vertically downward movement of the support 2 allows the scraper 5 to scrape off the paste from the surface of the blade 40. Through the coordinated movement of the mounting frame 3 and the support 2, the scraper 5 can scrape off the paste from the surface of the blade 40 multiple times from top to bottom. After scraping is complete, the cleaning component 9 can further clean the residual material on the surface of the blade 40. This eliminates the need for manual cleaning of the paste adhering to the blade 40, reducing the labor intensity of workers and improving work safety.
