[0002] In the production and processing of PVC flooring, the scraper is a crucial processing tool, and its performance and structure directly affect the processing quality and production efficiency. Traditional scrapers have many problems in their design and use.

[0003] Existing scrapers typically require complex clamps or multiple connecting parts to secure the tool during installation. This not only makes the installation process cumbersome but also makes it extremely inconvenient to replace worn-out tools. It often requires a lot of time and manpower to disassemble and reinstall the tool, which significantly affects the processing efficiency of the equipment. Utility Model Content

[0004] To address the shortcomings of existing scrapers, which typically require complex clamps or multiple connecting parts to secure the blades, making the installation process cumbersome and the replacement of worn blades extremely inconvenient, often requiring significant time and manpower for disassembly and reinstallation, thus greatly affecting the processing efficiency of the equipment, this utility model provides a scraper for processing PVC flooring.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a scraper for processing PVC flooring, comprising a blade mounting shaft, a blade disc, a blade mounting sleeve, and an adjustable mounting assembly. The blade mounting sleeve is fixedly mounted to one end of the blade mounting shaft via the adjustable mounting assembly. The blade mounting shaft has a threaded hole at its center, and the blade disc and the blade mounting sleeve have through holes at their centers that are adapted to the threaded holes.

[0007] The outer wall of the cutter disc is fixedly connected with scraper blades arranged in a ring around its perimeter.

[0008] As a preferred technical solution of this utility model, a groove adapted to the tool holder is provided on one side of the outer wall of the cutter disc around the perforation, and a limiting groove distributed in a ring is provided on the inner side wall of the groove. A limiting block adapted to the limiting groove is fixedly connected to the side of the outer wall of the tool holder near the cutter disc.

[0009] As a preferred embodiment of this utility model, a recessed groove is formed on the side of the outer wall of the cutter disc away from the groove.

[0010] As a preferred technical solution of this utility model, the adjustable mounting component includes a cylindrical groove formed around the outer side wall of the tool mounting shaft and a threaded groove formed on the inner side wall of the tool mounting sleeve. A threaded rod is threadedly connected to the threaded groove. One end of the threaded rod that is clamped in the cylindrical groove is fixedly connected to a cylindrical clamp head that is adapted to the cylindrical groove. The other end of the threaded rod that is away from the cylindrical clamp head is fixedly connected to a rotating handle.

[0011] As a preferred embodiment of this utility model, a scale is provided on the outer wall of the tool-loading shaft.

[0012] As a preferred embodiment of the present invention, the scraper body includes an inclined blade seat fixedly connected to the blade disc and a diamond blade head fixedly connected to the end of the inclined blade seat away from the blade disc.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of scraper for processing PVC flooring, through the cooperation of the blade shaft, blade disc, blade sleeve, adjustable mounting, threaded hole, through hole, and scraper body, allows for easy installation of the blade disc. When the blade disc needs to be installed, the blade disc is first fitted onto the blade sleeve, and then the bolt is threaded into the threaded hole after passing through the through hole in the blade disc and the blade sleeve, ensuring that the end of the bolt is tightly fitted onto the blade disc. The installation of the blade disc is thus completed. The entire installation process is simple to operate and has few steps, which can effectively reduce equipment downtime, improve the utilization rate of production equipment, and make the production process smoother and more efficient.

When the position of the tool holder needs to be adjusted, first remove the bolt from the threaded hole. Then, rotate the threaded rod by turning the handle, causing the threaded rod and the cylindrical chuck to move along the threaded groove away from the tool holder shaft until the cylindrical chuck is fully inserted into the threaded groove. Next, move the tool holder along the length of the tool holder shaft. When the tool holder has moved to the desired position, rotate the threaded rod again by turning the handle until the cylindrical chuck is fully inserted into the cylindrical groove. This completes the adjustment and positioning of the tool holder, allowing workers to quickly adjust the position of the tool holder according to their needs.

[0016] 3. This type of scraper for processing PVC flooring, through the cooperation of the limiting groove and the limiting block, can minimize the circumferential displacement of the cutter head during the installation process. When the scraper is working, the cutter head can be stably fixed on the cutter sleeve, minimizing the displacement or shaking of the cutter head due to vibration or cutting force, thereby effectively improving the stability of the cutting trajectory of the scraper body and the quality of the processed product.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides a scraper for processing PVC flooring, comprising a blade mounting shaft 1, a blade disc 2, a blade mounting sleeve 3, and an adjustable mounting assembly 4. The blade mounting sleeve 3 is fixedly mounted to one end of the blade mounting shaft 1 via the adjustable mounting assembly 4, and a scale 12 is provided on the outer wall of the blade mounting shaft 1.

[0026] Reference Figure 2 , Figure 3 and Figure 4The adjustable mounting component 4 includes a cylindrical groove 41 formed around the outer side wall of the tool mounting shaft 1 and a threaded groove 42 formed on the inner side wall of the tool mounting sleeve 3. A threaded rod 43 is threadedly connected to the threaded groove 42. One end of the threaded rod 43 that is locked in the cylindrical groove 41 is fixedly connected to a cylindrical chuck 44 that is adapted to the cylindrical groove 41. The diameter of the cylindrical chuck 44 is less than or equal to the diameter of the threaded rod 43, so that the cylindrical chuck 44 can move with the threaded rod 43 in the threaded groove 42. A rotating handle 45 is fixedly connected to the end of the threaded rod 43 away from the cylindrical chuck 44.

[0027] When it is necessary to adjust the position of the tool holder 3 on the tool shaft 3, first rotate the threaded rod 43 by turning the handle 45, so that the threaded rod 43 and the cylindrical chuck 44 move away from the tool shaft 1 along the thread groove 42 until the cylindrical chuck 44 is fully inserted into the thread groove 42. Then move the tool holder 3 along the length of the tool shaft 1, and determine the position of the tool holder 3 by observing the scale 12 during the movement.

[0028] After the tool holder 3 is moved to the required position, the threaded rod 43 is rotated again by turning the handle 45, which causes the threaded rod 43 and the cylindrical chuck 44 to move closer to the cylindrical chuck 41 until the cylindrical chuck 44 is fully inserted into the cylindrical chuck 41, thus completing the adjustment and positioning installation of the tool holder 3.

[0029] Reference Figure 3 , Figure 4 and Figure 5 The tool mounting shaft 1 has a threaded hole 5 at its center. The tool disc 2 and the tool mounting sleeve 3 have through holes 6 that are compatible with the threaded holes 5 at their centers. The outer side wall of the tool disc 2 has a groove 8 that is compatible with the tool mounting sleeve 3 around the through holes 6. The inner side wall of the groove 8 has a ring-shaped limiting groove 9 around its perimeter. The outer side wall of the tool mounting sleeve 3, near the tool disc 2, is fixedly connected to a limiting block 10 that is compatible with the limiting groove 9.

[0030] When it is necessary to install the cutter head 2, first attach the cutter head 2 to the tool holder 3, and ensure that the limit blocks 10 are all inserted into the limit grooves 9. Then, pass the bolt through the through holes 6 opened in the cutter head 2 and the tool holder 3 and thread it into the threaded hole 5, and ensure that the end of the bolt is tightly attached to the cutter head 2. The installation of the cutter head 2 can then be completed.

[0031] All four sides of the outer wall of the cutter disc 2 are fixedly connected with scraper blades 7 arranged in a ring. The scraper blade 7 includes an inclined blade seat 71 fixedly connected to the cutter disc 2 and a diamond cutter head 72 fixedly connected to the inclined blade seat 71 away from the cutter disc 2. After the cutter disc 2 is installed, the drive unit (not shown in the figure) will drive the blade mounting shaft 1 to rotate, which in turn drives the blade mounting sleeve 3, the cutter disc 2 and the scraper blade 7 fixedly connected to the cutter disc 2 to rotate. During the rotation of the scraper blade 7, the diamond cutter head 72 can perform scraping processing on the PVC floor.

[0032] Reference Figure 1 , Figure 2 and Figure 5 A recessed groove 11 is provided on the outer side of the cutter head 2 away from the groove 8. After the cutter head 2 is installed, the end of the bolt is located in the recessed groove 11. When the cutter head 2 and the scraper body 7 scrape the PVC floor, the recessed groove 11 on the cutter head 2 can change the structural shape of the cutter head 2, so that when the cutter head 2 is subjected to the force transmitted by the scraper body 7, the stress distribution is more reasonable, reducing the local stress concentration, thereby improving the structural strength and stability of the cutter head 2 and extending the service life of the cutter head 2.

[0033] The working principle of this utility model is as follows:

[0034] When it is necessary to install the cutter head 2, first attach the cutter head 2 to the tool holder 3, and ensure that the limit blocks 10 are all inserted into the limit grooves 9. Then, pass the bolts through the through holes 6 opened in the cutter head 2 and the tool holder 3 and thread them into the threaded holes 5, and ensure that the ends of the bolts are tightly attached to the cutter head 2. The installation of the cutter head 2 can then be completed.

[0035] When the position of the tool holder 3 needs to be adjusted, first remove the bolt from the threaded hole 5 by thread, and then rotate the threaded rod 43 by turning the handle 45, so that the threaded rod 43 and the cylindrical chuck 44 move along the threaded groove 42 away from the tool holder 1 until the cylindrical chuck 44 is fully inserted into the threaded groove 42.

[0036] Then, move the tool holder 3 along the length of the tool holder shaft 1, and determine the position of the tool holder 3 by observing the scale 12 during the movement. When the tool holder 3 moves to the required position, rotate the threaded rod 43 again by rotating the handle 45, so that the threaded rod 43 and the cylindrical chuck 44 move closer to the cylindrical chuck groove 41 until the cylindrical chuck 44 is completely inserted into the cylindrical chuck groove 41, and the adjustment and positioning installation of the tool holder 3 is completed.

[0037] After the cutter head 2 is installed, the drive unit (not shown in the figure) will drive the tool mounting shaft 1 to rotate, which in turn drives the tool mounting sleeve 3, the cutter head 2 and the scraper body 7 fixedly connected to the cutter head 2 to rotate. During the rotation of the scraper body 7, the diamond cutter head 72 can perform scraping processing on the PVC floor.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
