Description
Technical Field
[0001] The utility model relates to the technical field of scrapers, and more specifically, to a shock-absorbing scraper. Background Art
[0002] During screen printing and flat printing processes, the scraper needs to move smoothly on the printing plate to ensure that the ink is evenly transferred through the mesh holes to the substrate. However, traditional scrapers are prone to vibration during use, resulting in unstable printing quality. Therefore, a scraper that can effectively absorb shock is needed to improve printing quality and service life. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a shock-absorbing scraper to solve the above problems.
[0004] To achieve the above purpose, the technical solution provided by the utility model is as follows:
[0005] A shock-absorbing scraper of the utility model includes a knife base body. One end of the knife base body is provided with a knife edge, and the knife edge is inclined to reduce friction and improve the working efficiency of the scraper. A support surface is provided at the end of the knife base body where the knife edge is higher. A shock-absorbing groove is opened at the position below the support surface of the knife base body. A shock-absorbing component is arranged in the shock-absorbing groove. The shock-absorbing groove is an arc-shaped structure, which can effectively disperse vibration energy and improve the shock-absorbing effect. A corrugated groove is arranged on one side of the shock-absorbing groove close to the support surface, and the corrugated groove can increase the elasticity of the material and improve the shock-absorbing effect.
[0006] Preferably, a wear-resistant layer is provided on the knife edge and fixed at the position of the knife edge by welding or bonding to ensure its firmness and reliability, so as to improve the wear resistance of the knife edge.
[0007] Preferably, the support surface and the knife edge form an acute angle of 80°. The acute angle design can reduce the vibration generated during the movement of the scraper. The smaller contact area enables the scraper to recover balance more quickly when encountering an uneven surface. The acute angle design makes the scraper move more smoothly during use and is not prone to jamming, improving the scraping quality and stability.
[0008] Preferably, the shock-absorbing component includes a silica gel layer and a rubber layer. The silica gel layer and the rubber layer are glued together. The silica gel layer is made of high-elasticity silica gel, which has good shock-absorbing performance and heat resistance. A harder rubber is covered outside to improve the overall shock-absorbing effect and stability.
[0009] Preferably, the silica gel layer includes an arc surface section and an inclined surface section. The arc surface section and the inclined surface section are integrally formed. The inclined surface section is attached to the support surface, and the arc surface section is attached to the inner wall of the shock-absorbing groove
[0010] Preferably, a corrugated protrusion matching the corrugated groove is provided at a position of the arc surface section close to the corrugated groove. The corrugated protrusion is filled into the corrugated groove, which not only absorbs shock but also assists the corrugated groove to reset.
[0011] Preferably, the rubber layer has an arc-shaped structure and is adhered to the arc surface section, playing a supporting role for the arc surface section and being responsible for the arc surface section to return to its original state.
[0012] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0013] A shock-absorbing scraper of the present utility model effectively reduces vibrations during use and improves scraping quality by providing an arc-shaped shock-absorbing groove on the side wall of the tool base body and attaching a highly elastic silica gel material to form an integral silica gel layer. A harder rubber is covered on the outside of the silica gel layer to improve the overall shock absorption effect and stability. The corrugated groove and the corrugated protrusion further improve the shock absorption effect of the shock-absorbing groove. The setting of the wear-resistant layer improves the durability of the cutting edge and extends the service life of the scraper. The overall structure is simple, easy to produce and maintain.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.
[0020] Combined with Figures 1-3, a shock-absorbing scraper of the present utility model includes a knife base body. One end of the knife base body is provided with a cutting edge 1, and the cutting edge 1 is used for scraping work. The cutting edge 1 is inclined, and the inclined plane angle is 15° to reduce friction and improve the working efficiency of the scraper. In order to improve the wear resistance of the cutting edge 1, a wear-resistant layer 11 is provided on the cutting edge 1. The wear-resistant layer 11 is made of polyurethane material with a thickness of 2 mm and is fixed at the position of the cutting edge 1 by welding or bonding to ensure its firmness and reliability, so as to improve the wear resistance of the cutting edge 1.
[0021] At the high end of the knife base body where the cutting edge 1 is located, a support surface 2 is provided. The angle between the support surface 2 and the horizontal plane is 85°. Therefore, the support surface 2 and the cutting edge 1 form an acute angle of 80°. The acute angle design can reduce the vibration generated during the movement of the scraper. The smaller contact area enables the scraper to quickly regain balance when encountering an uneven surface, reducing the vibration transmitted to the operator's hand. At the same time, the acute angle design makes the scraper smoother during use and less likely to get stuck, improving the scraping quality and stability.
[0022] A shock-absorbing groove 3 is opened at the position of the knife base body below the support surface 2. The shock-absorbing groove 3 is an arc-shaped structure, which can effectively disperse the vibration energy. A shock-absorbing component 4 is arranged in the shock-absorbing groove 3 to improve the shock-absorbing effect. In addition, a corrugated groove 31 is arranged on one side of the shock-absorbing groove 3 close to the support surface 2. The corrugated groove 31 can increase the elasticity of the material and improve the shock-absorbing effect.
[0023] The shock-absorbing component 4 includes a silica gel layer 41 and a rubber layer 42. The silica gel layer 41 is made of high-elastic silica gel, which has good shock-absorbing performance and heat resistance. A harder rubber is covered outside to improve the overall shock-absorbing effect and stability. The silica gel layer 41 includes an arc section 411 and an inclined plane section 412. The arc section 411 and the inclined plane section 412 are integrally formed. The inclined plane section 412 fits with the support surface 2, and the arc section 411 fits with the inner wall of the shock-absorbing groove 3. At the position of the arc section 411 close to the corrugated groove 31, a corrugated protrusion 4111 matching the corrugated groove 31 is arranged. The corrugated protrusion 4111 is filled into the corrugated groove 31. While absorbing shock, it assists the corrugated groove 31 to reset.
[0024] The rubber layer 42 is an arc-shaped structure and covers the outside of the arc section 411, playing a supporting role for the arc section 411 and being responsible for the arc section 411 to return to its original state.
[0025] Working process: First, the tool base body is processed, and the wear-resistant layer 11 is bonded at the position of the cutting edge 1, and the silica gel layer 41 is bonded in the support surface 2 and the shock-absorbing groove 3. Finally, the rubber layer 42 is bonded to the arc surface section 411. During operation, the wear-resistant layer 11 contacts the scraping surface for scraping. The inclined setting of the cutting edge 1 reduces the friction force, and under the action of the shock-absorbing groove 3 and the silica gel layer 41, a certain amount of vibration is absorbed. The rubber layer 42 assists the arc surface section 411 and the shock-absorbing groove 3 to reset. The corrugated groove 31 can increase the elasticity of the shock-absorbing groove 3 and improve the shock-absorbing effect.
