The rotating shaft of the motor B203 is provided with a thread, and the rotating shaft of the motor B203 is located at the middle position inside the transverse frame 202. The front end position of the transverse frame 202 longitudinally slides with the upper rear position of the rear end of the lifting frame 204. A threaded hole is provided at the middle rear position of the top of the lifting frame 204, and the rotating shaft of the motor B203 is located in the threaded hole of the lifting frame 204.

[0034] Among them, a driving motor 205 is fixedly installed at the front end position of the lifting frame 204. The rotating shaft of the driving motor 205 is fixedly connected to the middle position of the rear end of the shaving wheel 206. The front surface of the shaving wheel 206 is designed in the shape of a gear, and the side of the shaving wheel 206 is designed in the shape of a rack. Conical shaving blocks are arrayed on its surface. Combining the self - design of the shaving wheel 206, when the shaving wheel 206 and the material strip 5 are in a cross - distribution state, dry cutting and shaving of the material strip 5 can be performed. After the processing of the material strip 5 is completed, the material strip 5 rotates 90 degrees and meshes with the shaving wheel 206 in parallel. The shaving wheel 206 can meshingly drive the material strip 5 to perform lateral position movement detection to ensure that the saw - tooth positions processed by the shaving wheel 206 on the material strip 5 meet the standards, achieving multiple functions.

[0035] Among them, a material strip 5 is placed at the top position of the following frame 4. The material strip 5 is located between two opposing sliders 403 and two extension frames 405.

[0036] Among them, a motor C301 is fixedly installed at the front end position of the feeding frame 3. A threaded hole is provided in the rotating shaft of the motor C301, and the rotating shaft of the motor C301 is located in the threaded hole of the feeding block 302. A stretchable and retractable telescopic cover 303 is installed at each of the front and rear ends of the feeding block 302, and the other ends of the two telescopic covers 303 are both fixedly connected to the feeding frame 3.

[0037] During use: Place the material strip 5 at the top position of the follower 4, such that the material strip 5 is located between the two opposing sliders 403 and the two extension frames 405. The front end position of the material strip 5 abuts against the top baffle of the limiting frame 401. Rotating the opposing screw 402 enables the two opposing sliders 403 to slide towards each other within the chute of the limiting frame 401. By adjusting the positions of the two opposing sliders 403, the fitting members 404 provided at the middle positions of each opposing slider 403 are used to fixedly position both sides of the material strip 5, and the material strip 5 is kept centered at the middle position of the top of the follower 4. Meanwhile, the auxiliary fitting members 406 provided on the extension frames 405 simultaneously adhere to both sides of the material strip 5. When processing the material strip 5, start the motor C301 fixedly installed at the front end position of the feeding rack 3. When the rotating shaft of the motor C301 rotates, it drives the feeding block 302 to slide within the feeding rack 3. At this time, the follower 4 follows the feeding block 302 and slides at the top position of the equipment rack 1 to adjust the grinding and feeding position of the material strip 5. During the feeding process, the extendable and retractable telescopic covers 303 installed at the front and rear ends of the feeding block 302 extend or contract accordingly, playing a role in protection and preventing foreign objects from entering.

[0038] Combined with the length of the material strip 5, rotate the screw member 103 so that the screw member 103 rotates within the threaded hole of the positioning block 102, thereby driving the positioning block 102 to slide at the middle and rear positions within the groove of the equipment rack 1. Adjust the positioning block 102 to a suitable position to ensure that the front end position of the abutting block 107 contacts the rear end position of the material strip 5.

[0039] Start the motor A201. The rotating shaft of the motor A201 cooperates with the threaded hole of the transverse frame 202, thereby driving the transverse frame 202 to slide horizontally at the front middle position of the adjusting frame 2 to adjust the horizontal position of the shaving wheel 206. Start the motor B203. The rotating shaft of the motor B203 rotates within the threaded hole of the lifting frame 204, thereby driving the lifting frame 204 to slide longitudinally at the front end position of the transverse frame 202 to adjust the longitudinal position of the shaving wheel 206, such that the shaving wheel 206 reaches a suitable processing position relative to the material strip 5. Drive the rotating shaft of the driving motor 205 to drive the shaving wheel 206 to rotate. Since the front surface of the shaving wheel 206 is designed in the shape of a gear and the side surface is designed in the shape of a rack, with conical shaving blocks arrayed on its surface, the material strip 5 is subjected to shaving tooth processing during rotation.

[0040] When the material strip 5 is processed and cut, the air cylinder 105 is started to lower the abutting block 107 to release the abutting on the material strip 5. The rotation of the rotating shaft of the motor C301 drives the feeding block 302 to slide backward inside the feeding frame 3, so that the material strip 5 can be unloaded from the rear of the equipment frame 1, avoiding the situation that the device needs to be reset to unload the material. At the same time, considering that the gap between the two supporting plates 407 is greater than the width of the abutting frame 106, after the following frame 4 moves backward, there will be no interference between the two supporting plates 407 and the abutting frame 106 to affect the continuous backward movement of the following frame 4.

[0041] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure shall be subject to the protection scope of the claims.
