[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0017] Example 1: Please refer to Figures 1 to 2 A grinding machine for plastic processing tools includes a machine body 1, a drive motor 2, and a grinding mold body 3. The grinding mold body 3 is slidably engaged on the machine body 1, and the drive motor 2 is disposed on the grinding mold body 3. The drive motor 2 drives the grinding mold body 3 to slide on the upper side of the machine body 1. A guide component, a collection component, and a cleaning component are disposed inside the machine body 1. The guide component is disposed on both sides of the machine body 1, the collection component is disposed on the guide component, and the cleaning component is disposed on the upper side of the guide component.

[0018] The inclined guide grooves 301 in the guide assembly are evenly arranged on the inclined plate 302, which is located at both ends of the bottom of the machine body 1.

[0019] In use, the operator first fixes the plastic processing tool to be ground in the designated clamping position on the machine body 1, and then starts the drive motor 2. The drive motor 2 drives the grinding mold body 3 to slide along the preset trajectory on the upper side of the machine body 1. The grinding mold body 3 contacts the cutting edge of the tool and begins the grinding operation. The plastic debris and grinding mold wear powder generated during the grinding process fall onto the inclined plates 302 on both sides of the bottom of the machine body 1 under the action of gravity. Since the inclined plates 302 are set at an angle and have evenly distributed inclined guide grooves 301, the waste will automatically enter the inclined guide grooves 301 and flow towards the bottom end of the inclined plate 302 along the inclined direction of the inclined guide grooves 301. The setting of the inclined guide grooves 301 plays a directional constraint role on the waste, preventing the waste from being scattered randomly inside the machine body 1, laying the foundation for subsequent centralized collection, and at the same time keeping other areas inside the machine body 1 relatively clean.

[0020] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The collection box 401 in the collection assembly is fixedly installed on the collection seat 402, and the collection seat 402 is located at the bottom end of the inclined plate 302.

[0021] The collection box 401 in the collection assembly is provided with guide arc plates 403 on both sides. The guide arc plates 403 are connected to the bottom end of the inclined guide groove 301. The collection box 401 is provided with an outlet 404 on one side, which is connected to the drainage groove.

[0022] During use, as the sharpening operation proceeds, the waste chips in the inclined guide groove 301 continuously move towards the bottom end of the inclined plate 302. When the waste chips reach the bottom end of the inclined guide groove 301, the guide arc plates 403 on both sides of the collection box 401 play a guiding role. Their arc structure can smoothly receive the waste chips flowing out from the inclined guide groove 301, preventing the waste chips from accumulating at the joint. The waste chips smoothly enter the collection box 401 through the guide arc plates 403. The collection seat 402 provides stable support for the collection box 401, ensuring that the collection box 401 remains in a fixed position during the waste chip collection process. When the waste chips in the collection box 401 accumulate to a certain amount, the waste chips can enter the connected drainage trough through the outlet 404 on one side of the collection box 401. The drainage trough transports the waste chips to the designated waste collection container, realizing the centralized discharge and treatment of waste chips and reducing the frequency of manual cleaning of the collection box 401.

[0023] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The rotating rod 501 in the cleaning assembly is installed on the upper side of the inclined guide groove 301, and the sleeve 502 is sleeved on the rotating rod 501.

[0024] Guide brushes 503 are evenly arranged on the sleeve 502 of the cleaning assembly. A scraper protrusion 504 is provided on one side of the guide brush 503. The guide brush 503 and the scraper protrusion 504 are in close contact with the inner side of the inclined guide groove 301.

[0025] During use, the cleaning components operate simultaneously with the start of the sharpening machine. The external drive structure drives the rotating rod 501 to rotate on the upper side of the inclined guide groove 301. As the rotating rod 501 rotates, it drives the sleeve 502 to rotate as well. The guide brush 503 and scraper protrusion 504 on the sleeve 502 are in close contact with the inner side of the inclined guide groove 301. During rotation, they clean the inner wall of the inclined guide groove 301. The scraper protrusion 504 can scrape off the more stubborn adhesive waste in the groove, while the guide brush 503 further cleans the fine waste remaining in the groove, ensuring that there is no waste accumulation on the inner side of the inclined guide groove 301. The cleaned waste flows to the collection box 401 along with the main waste in the inclined guide groove 301, effectively preventing the inclined guide groove 301 from being blocked by waste and affecting the waste conveying efficiency. The entire cleaning process is carried out simultaneously with the sharpening operation, without the need for additional manual operation, which improves the automation level and ease of use of the equipment.

[0026] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
