[0009] By adopting the above technical scheme, the pencil stripping machine can realize the individual painting of a certain specific side of the pencil, improve the processing precision and diversity of the pencil, and meet different production needs. Specifically, the plurality of scraping surfaces of the paint scraping rubber ring correspond one-to-one to the plurality of sides of the pencil, one scraping surface has a gap with the side of the pencil, and the remaining scraping surfaces are in close contact with the sides of the pencil, so as to ensure that only the selected one side is painted, and the other sides remain unchanged. The setting of the fixing assembly further ensures the stability and reliability of the paint scraping rubber ring.

[0010] Preferably, the fixing assembly comprises a fixing plate and a locking bolt, the fixing plate is provided with a through hole opposite to the pencil outlet, the paint scraping rubber ring is arranged between the fixing plate and the side wall of the paint box and located at the through hole, and the fixing plate is fixedly connected with the paint box through the locking bolt.

[0011] By adopting the technical scheme, the structure design of the fixing assembly enables the paint scraping rubber ring to be firmly installed at the pencil outlet, ensuring the position stability and sealing performance of the paint scraping rubber ring. The through hole on the fixing plate is opposite to the pencil outlet, so that the pencil can pass through smoothly, and the paint scraping rubber ring is arranged between the fixing plate and the side wall of the paint box, and is tightly attached to the surface of the pencil through the fixing effect of the locking bolt, effectively scraping off the excess paint and ensuring the uniformity of the paint layer on the surface of the pencil.

[0012] Preferably, the through hole is provided with a taper hole on the side facing the paint scraping rubber ring, and the inner wall of the taper hole is in abutment with the paint scraping rubber ring, so that the paint scraping rubber ring is contracted.

[0013] By adopting the technical scheme, the taper hole design enables the paint scraping rubber ring to contract when subjected to pressure, so as to be more tightly attached to the surface of the pencil, further improving the paint scraping effect and ensuring the uniformity of the paint layer.

[0014] In summary, the present application has at least one of the following beneficial technical effects:

[0015] 1. By arranging multiple scraping surfaces of the paint scraping rubber ring in one-to-one correspondence with multiple side surfaces of the pencil, one of the scraping surfaces is left with a gap from the side surface of the pencil, and the remaining scraping surfaces are tightly attached to the side surface of the pencil, so as to realize single-surface painting of the pencil and meet the diversified needs of pencil production;

[0016] 2. The design of the paint scraping rubber ring enables the paint layer on the surface of the pencil to be more uniform, avoiding the problem of inconsistent paint layer thickness caused by uneven pressure of the traditional rubber ring and improving the quality of pencil surface treatment;

[0017] 3. The fixing assembly firmly fixes the paint scraping rubber ring at the pencil outlet through the fixing plate and the locking bolt, ensuring the stability and reliability of the paint scraping rubber ring during operation and prolonging the service life of the equipment.

[0021] The following will be described in detail below Figures 1-2 The application is further described in detail.

[0022] The application discloses a pencil stripping machine.

[0023] The pencil stripping machine provided by the application has the advantages of Figure 1 and Figure 2 It includes a paint box 1 and a paint scraping device 2. The paint box 1 has a pen outlet 11, and the paint scraping device 2 is arranged at the pen outlet 11. The paint scraping device 2 includes a paint scraping rubber ring 21 and a fixing assembly 22. The paint scraping rubber ring 21 has multiple scraping surfaces and a central hole. One of the multiple scraping surfaces corresponds to one side surface of the pencil, and the rest of the scraping surfaces are in close contact with the side surfaces of the pencil. The fixing assembly 22 is used for fixing the paint scraping rubber ring 21.

[0024] The paint scraping rubber ring 21 includes multiple scraping surfaces and a central hole. The scraping surfaces can be made of flexible materials such as natural rubber or synthetic rubber, which have good elasticity and wear resistance and can maintain good sealing effect after multiple uses. The design of the central hole allows the pencil to pass through smoothly without affecting the paint scraping effect.

[0025] The fixing assembly 22 includes a pressing plate and a locking bolt 222. The pressing plate is provided with a through hole 223 opposite the pen outlet 11, and the paint scraping rubber ring 21 is arranged between the pressing plate and the side wall of the paint box 1 and located at the through hole 223. The pressing plate can be fixedly connected with the paint box 1 through the locking bolt 222, so as to ensure that the paint scraping rubber ring 21 does not loosen during work. The material of the pressing plate can be metal or high-strength plastic to ensure its stability during long-term use.

[0026] The through hole 223 on the pressing plate can be designed in various shapes, such as circular, oval or square. The edge of the through hole 223 can be chamfered to reduce the wear on the surface of the paint scraping rubber ring 21. The connection between the pressing plate and the side wall of the paint box 1 can also adopt buckle connection or other reliable fixing methods to ensure the stability of the connection.

[0027] The side of the through hole 223 facing the paint scraping rubber ring 21 is designed as a tapered hole, and the inner wall of the tapered hole is in abutment with the paint scraping rubber ring 21, so as to shrink the paint scraping rubber ring 21. The design of the tapered hole can increase the sealing property of the paint scraping rubber ring 21, so that it can better fit the surface of the pencil, thereby improving the paint scraping effect.

[0028] The implementation principle of the embodiment is that when the pencil is painted, firstly, all surfaces of the pencil are painted by using a traditional pencil paint machine. Then, the paint is dried by using a drying device.

[0029] After the pencil paint is dried, a pencil stripping machine in the application is used to paint a certain surface of the pencil. When the pencil passes through the paint box 1, one scraping surface of the paint scraping rubber ring 21 leaves a gap with one surface of the pencil, and the other scraping surfaces are in close contact with the other surfaces of the pencil, so that the single painting of the certain surface of the pencil is realized. The setting of the fixing assembly 22 ensures the stability and reliability of the paint scraping rubber ring 21 during the working process.

[0030] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
