Detailed Implementation

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-5 As shown, the system includes a base 100, a lifting assembly 200 at the upper end of the base 100, a shearing assembly 300 outside the lifting assembly 200, a mounting block 301, a shearing head 302 fixedly connected to the lower end of the mounting block 301, and a cleaning assembly 400 at the lower end of the mounting block 301. The cleaning assembly 400 includes a limiting groove 401 formed at the lower end of the mounting block 301, and a positive and negative lead screw 4 is rotatably connected to the inner wall of the limiting groove 401. 02. Two limiting blocks 403 are threadedly connected to the outer side of the positive and negative lead screw 402. A cleaning plate 404 is fixedly connected to the side of the limiting block 403 near the shear head 302. One end of the positive and negative lead screw 402 is rotatably connected to the mounting block 301. The end of the positive and negative lead screw 402 that passes through the mounting block 301 is fixedly connected to the output end of the motor 405. The lower end of the motor 405 is fixedly connected to the support frame 406. One end of the support frame 406 is fixedly connected to the mounting block 301.

[0026] Specifically, when cleaning the shear head 302 is required, the operator starts the drive motor 405. This motor 405 drives the forward and reverse lead screws 402 to rotate. This rotational motion is converted into linear displacement of two symmetrically arranged limit blocks 403 via threaded transmission, which in turn drives the special cleaning plate 404 mounted on the limit blocks 403 to move synchronously in opposite directions. Once the cleaning plate 404 has moved to a working position completely in contact with the surface of the shear head 302, the operator can start the shear head 302, causing it to rotate at a set speed. During this process, the specially designed scraping edge on the cleaning plate 404 generates relative motion with the rotating surface of the shear head 302, thoroughly scraping away the debris adhering to the tool surface. This automated cleaning mechanism effectively solves the problems of tool edge dulling, increased shearing dimensional deviation, and increased load on the equipment transmission system caused by debris accumulation in traditional machining, significantly improving machining accuracy and equipment operational stability.

[0027] Please see Figure 1-5 As shown, the lifting assembly 200 includes a fixing block 201 fixedly connected to the upper end of the base 100. A reciprocating screw 202 is rotatably connected to the upper end of the fixing block 201. The top end of the reciprocating screw 202 passes through and is threadedly connected to the mounting block 301. A handle 203 is fixedly connected to one end of the reciprocating screw 202 that passes through the mounting block 301. A traction tube 204 is fixedly connected to the upper end of the fixing block 201. The traction tube 204 passes through and is slidably connected to the mounting block 301. A fixing assembly 500 is provided at the upper end of the base 100. The fixing assembly 500 includes two mounting plates 501 fixedly connected to the upper end of the base 100. The inner wall of the base 100 is fixedly connected to a multi-stage electric telescopic column 502. A positioning plate 503 is fixedly connected to the side of the multi-stage electric telescopic column 502 away from the mounting plate 501. An installation groove 504 is opened at the end of the positioning plate 503 away from the multi-stage electric telescopic column 502. A friction pad 505 is fixedly connected to the inner wall of the installation groove 504. A collection component 600 is provided at the upper end of the base 100. The collection component 600 includes a material collection trough 601 opened at the upper end of the base 100. The material collection trough 601 penetrates the base 100. An anti-slip film 602 is fixedly connected to the inner wall of the material collection trough 601. A material collection box 603 is fixedly connected to the lower end of the material collection trough 601.

[0028] Specifically, in the initial working state of the equipment, the operator first needs to place the Teflon duct raw material sheet flat on the processing platform and carefully adjust the position of the sheet to ensure that the area to be sheared is precisely aligned with the center line of the cutting edge of the shear head 302. After confirming accurate alignment, the electric telescopic column 502 is activated, driving the positioning plate 503 to move. The friction pad 505 significantly enhances the fixing effect, preventing the sheet from shifting during the shearing process. Subsequently, the operator rotates the handle 203 clockwise, driving the reciprocating screw 202 to rotate, causing the mounting block 301 to descend smoothly along the vertical guide rail. The shear head 302 then moves to the preset cutting height. The strip-shaped or granular waste generated during the shearing process falls naturally into the collection trough 601 under gravity, and finally collects in the detachable collection box 603. The PTFE anti-slip film 602 covering the inner wall of the collection trough 601 has excellent non-stick properties, which can effectively prevent fine waste from adhering and ensure the continuous smooth flow of the waste collection system. The entire workflow has been optimized from plate positioning, clamping, shearing to waste collection, significantly improving production efficiency and product quality.

[0029] In use, during the initial operation of this invention, the operator first needs to place the Teflon duct raw material sheet flat on the processing platform and carefully adjust its position to ensure precise alignment between the area to be sheared and the center line of the cutting edge of the shear head 302. After confirming accurate alignment, the electric telescopic column 502 is activated, moving the positioning plate 503. The friction pad 505 significantly enhances the fixing effect, preventing displacement of the sheet during shearing. Subsequently, the operator rotates the handle 203 clockwise, driving the reciprocating screw 202 to rotate, causing the mounting block 301 to descend smoothly along the vertical guide rail. The shear head 302 then moves to the preset cutting height. The strip-shaped or granular waste generated during shearing falls naturally into the collection trough 601 under gravity and eventually collects in the detachable collection box 603. The PTFE anti-slip film 602 covering the inner wall of the receiving trough 601 has excellent non-stick properties, effectively preventing the adhesion of fine waste debris and ensuring the continuous smooth flow of the waste collection system. When cleaning the shear head 302 is required, the operator starts the drive motor 405. The motor 405 drives the forward and reverse lead screws 402 to rotate. This rotational motion is converted into linear displacement of two symmetrically arranged limit blocks 403 through threaded transmission, which in turn drives the special cleaning plate 404 mounted on the limit blocks 403 to move synchronously in opposite directions. When the cleaning plate 404 moves to the working position where it is completely in contact with the surface of the shear head 302, the operator can start the shear head 302 to rotate at a set speed. During this process, the specially designed scraping edge on the cleaning plate 404 generates relative motion with the rotating surface of the shear head 302, thoroughly scraping away the waste debris attached to the blade surface.
