Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and more specifically, to a sawing device with an automatic control system and its method of use. Background Technology

[0002] PCB, short for Printed Circuit Board, is a support structure for electronic components and the carrier of their electrical connections. It's named "printed" because it's manufactured using electronic printing techniques. For stationary electronic components, the principle of minimizing the distance between them is crucial for proper layout. PCB design includes determining the size of the layout, component placement, input / output port locations, and wiring design. The PCB manufacturing process involves multiple steps, including schematic design, material preparation, drilling, electroplating, circuit fabrication, solder mask application, character printing, surface treatment, assembly, testing, and packaging. Each step requires precise operation and strict quality control to ensure the performance and reliability of the final product.

[0003] During PCB manufacturing, to remove burrs and uneven areas from the PCB edges, improve edge smoothness and aesthetics, and ensure the PCB dimensions meet design requirements, providing accurate references for subsequent assembly and connection, edge trimming or grooving is performed. This is done using edge trimming equipment. An edge trimming equipment is a specialized machine used for trimming or cutting the edges of materials such as boards, wood, aluminum alloys, and plastics.

[0004] Currently, there are PCB board processing and cutting devices, such as the PCB board cutting device disclosed in application number CN201920584913.0. This utility model solves the problem that although the existing PCB board cutting machine has scales at both ends, its usability is not high, it is inconvenient for the PCB board cutting machine to cut at multiple angles and directions, and the exposed saw blade of the PCB board cutting machine is prone to causing injury to workers. By improving and optimizing the structure of the PCB board cutting machine, the usability of the scales at both ends of the PCB board cutting machine is high, which makes it easier for the PCB board cutting machine to cut the PCB board at multiple angles and directions.

[0005] However, the device has problems during use. First, it cannot process multiple workpieces of the same specification at the same time. For PCB boards that are generally small in size, manual cutting requires repeated loading and unloading, as well as repeated confirmation of the required cutting edge size. This makes it inconvenient to clamp and fix multiple workpieces of the same specification, resulting in low processing efficiency. Summary of the Invention

[0012] A further technical solution of this application: the sawing assembly also includes a base plate installed at the bottom of the mounting cavity, a second drive motor is provided on the base plate, a drive belt is connected to the outside of the power output shaft of the second drive motor, and the other end of the drive belt is connected to the outside of the first transmission shaft.

[0014] A further technical solution of this application: The clamping member includes a receiving groove formed on the inner side of the clamping member, a frame slidably installed inside the receiving groove, and a strip installed at the center of the upper end of the frame. A top groove is formed at the top of the receiving groove, and an adjusting cylinder is installed in the top groove. The strip is inserted into the top groove, and the end of the adjusting cylinder is connected to the end face of the strip. The inner side of the frame is a hollow structure, and several partitions are symmetrically arranged on both sides below the frame. A storage gap is formed between the partitions. A moving groove is also formed on the upper end of the frame corresponding to the storage gap. Two moving blocks are slidably connected to both ends inside the moving groove. An extension block is connected below each moving block. The extension block can be stored in the storage gap. The profile strip has symmetrical grooves on both sides. Each groove has an embedded groove corresponding to the position of the moving groove. A spring block and a rotating shaft are slidably connected inside the embedded groove.

[0015] A further technical solution of this application: rollers are sleeved on the lower end of the rebound block and the lower end of the rotating shaft, and the rollers rotate inside the inner groove; The top section of the extension block extending to the outer part of the storage gap is a parallelogram, and the side near the clamping member is a bevel.

[0016] A method of using a sawing device with an automatic control system, the method comprising the following steps: Step 1: Adjust the position of the clamping assembly on the table and the distance between each clamping mechanism inside the clamping assembly to meet the edge cutting of workpieces of different widths. When placing the workpiece, the side to be cut should be on the saw groove. When adjusting, first slide the clamping assembly to push the entire clamping assembly on the convex edge to adjust the size of the edge to be cut on the workpiece, and then adjust the spacing of the clamping mechanisms inside the clamping assembly. Step 2: When adjusting the spacing of the clamping mechanism, the first drive motor operates, driving the drive screw to rotate, thus rotating the active block. Since the active block is slidably connected to the slide rod on both sides, the rotation of the active block is restricted, allowing the active block to move. During the displacement of the active block, the auxiliary rod connected to it moves along with it. At the same time, the auxiliary rod drives its connected rotating rod to move. The rotating rod will rotate along the rotating column, and the angle between each pair changes, contracting or lengthening, which is changed according to the direction of movement of the active block. At the same time, during the movement of multiple rotating rods, they will drive their connected driven blocks to move along with them. The driven block closest to the first side plate and the rotating rod above it will drive the auxiliary rod below the first side plate to rotate outside the rotating column, limiting the maximum expansion length. In this way, the spacing between multiple driven blocks is adjusted. The driven blocks move along the slide rod, and at the same time, the clamping mechanisms on the sides of the driven blocks and the active block move along with them, completing the spacing adjustment. Step 3: Place multiple workpieces that need to be sawed on the table in the gaps formed by multiple clamping mechanisms, ensuring that the side that needs to be sawed is outside the saw groove. Then, the first drive motor works to drive the active block and the driven block to move closer together, so that the clamping parts in the clamping mechanism can move closer to each other. Then, the clamping parts work to make fine adjustments to their length, extending outward or retracting inward, to ensure that the clamping parts can completely fit against both sides of the workpiece. Step 4: The sawing assembly operates via the second drive motor, which drives the drive belt to rotate. As the drive belt rotates, it drives the first transmission shaft to rotate. When the first transmission shaft rotates, it drives the outer transmission belt to rotate, thus moving the belt buckle and the third mounting plate. The belt buckle and the third mounting plate move along the guide rail, which in turn moves the saw blade. Simultaneously, the third drive motor operates to drive the saw blade to rotate, thus moving the sawing edge.

[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention, by setting up a processing table, a clamping assembly, and a sawing edge assembly, firstly allows for the adjustment of the sawing edge size by adjusting the distance between the clamping assembly and the saw groove, making operation convenient and allowing for quick adjustment of the approximate length required to fix the workpiece, facilitating rapid material loading. Secondly, the multiple clamping mechanisms connected to the outside of the sawing edge assembly can be quickly disassembled and replaced, facilitating subsequent maintenance of the clamping components. Furthermore, the clamping components can extend again after clamping both sides of the workpiece, allowing for fine-tuning and comprehensive fixation of the workpiece. Multiple clamping mechanisms can be operated simultaneously, adjusting multiple gaps to meet the clamping and fixing needs of multiple workpieces of the same specifications, significantly improving efficiency.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0021] Please see Figures 1 to 11 In one embodiment of this application, a sawing device with an automatic control system includes a processing table 1. The processing table 1 is composed of a support frame 105 and a table surface 101 set at the top. An installation cavity is formed in the support frame 105, and a sawing component 3 is disposed in the installation cavity. A saw groove 102 is opened on the table surface 101, and the sawing component 3 extends to the table surface 101 through the saw groove 102. On the table 101, two protruding ribs 106 are arranged parallel to each other at both ends of the saw groove 102, and a sliding clamping component 2 is arranged between the two protruding ribs 106. The clamping assembly 2 includes a first side plate 201 and a second side plate 208 arranged in a mirror image, and a drive screw 217 connecting the first side plate 201 and the second side plate 208. A mounting base 207 is also provided on the outer side of the second side plate 208. A first drive motor 211 connected to the drive screw 217 is provided on the mounting base 207. Two slide rods 204 are symmetrically arranged on both sides of the drive screw 217 between the first side plate 201 and the second side plate 208. An active block 202 is threadedly connected to one end of the drive screw 217 near the second side plate 208, and the two ends of the active block 202 are slidably disposed on the two slide rods 204. Multiple driven blocks 206 are slidably connected between the two slide rods 204 and the drive screw 217 between the active block 202 and the first side plate 201. Rotating columns 210 are provided at the upper center of the active block 202 and the driven block 206, as well as at the lower part of the upper end of the first side plate 201. A rotating rod 203 is connected to the driven block 206 through the rotating column 210. Multiple driven blocks 206 are spliced ​​together by connecting the two ends of the rotating rod 203 in sequence. One end of the auxiliary rod 209 is connected to the lower part of the upper end of the active block 202 and the first side plate 201 through the rotating column 210, and the other ends of the two auxiliary rods 209 are respectively connected to the ends of the two outermost rotating rods 203. The side end faces of the active block 202 and the driven block 206 are connected to clamping mechanisms, and the clamping mechanisms are attached to the upper end face of the table 101.

[0022] This embodiment is implemented as follows: In actual use, firstly, the position of the clamping component 2 on the table 101 and the distance between each clamping mechanism in the clamping component 2 are adjusted to meet the edge cutting of workpieces of different sizes. When placing, the side to be cut should be on the saw groove 102. When adjusting, firstly, by sliding the clamping component 2, the entire clamping component 2 is pushed on the protruding edge 106 to roughly adjust the approximate edge of the workpiece to be cut and roughly fix it. It is important to note that at this time, one end of the workpiece should be in complete contact with the side of the clamping assembly 2. Then, adjust the spacing of the clamping mechanism inside the clamping assembly 2. During the adjustment of the clamping mechanism spacing, the first drive motor 211 operates, driving the drive screw 217 to rotate, thus rotating the active block 202. Since the active block 202 is slidably connected to the slide rod 204 on both sides, this restricts the rotation of the active block 202, allowing for its displacement. During the displacement of the active block 202, the auxiliary rod 209 connected to it moves accordingly. Simultaneously, the auxiliary rod 209 drives its connected rotating rod 203 to move. The rotating rod 203 will move along the rotating column 210. The rotation causes changes in the angle between each pair of blocks, resulting in contraction or extension. The direction of movement of the active block 202 changes accordingly. Simultaneously, multiple rotating rods 203 drive their respective connected driven blocks 206 to move along with them. The driven block 206 closest to the first side plate 201 and the rotating rod 203 above it drive the auxiliary rod 209 below the first side plate 201 to rotate outside the rotating column 210, limiting the maximum extension length. This completes the adjustment of the spacing between the multiple driven blocks 206. The driven blocks 206 are attached to the sliding rod 204 for displacement. At the same time, the clamping mechanisms on the sides of the driven blocks 206 and the active block 202 follow the displacement, completing the spacing adjustment.

[0023] Subsequently, the clamping member 205 can be used to extend from inside the clamping member 205 to ensure that the clamping member 205 can fully clamp both sides of the workpiece and reduce shaking.

[0024] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As a preferred embodiment of this application, the clamping mechanism includes a splicing groove 213 formed on the side end face of the active block 202 and the driven block 206, and a splicing block 215 is inserted into the splicing groove 213. A magnetic sheet 216 is provided at the end of the splicing block 215, and the magnetic sheet 216 can be magnetically attracted to the bottom of the splicing groove 213. A clamping member 205 is connected to the outer side of the lower end of the splicing block 215. Furthermore, the splicing groove 213 has symmetrically provided positioning grooves 212 on both sides near the opening end, and the splicing block 215 has symmetrically provided positioning blocks 214 on both sides that are spliced ​​with the positioning grooves 212.

[0025] This embodiment is implemented as follows: In actual use, since the side shapes of PCB workpieces of different specifications are not the same, in order to fix PCB workpieces of different shapes, multiple clamping parts 205 of different shapes can be made and connected to the splicing block 215. The splicing block 215 is used in conjunction with the magnetic sheet 216 to magnetically attract with the splicing groove 213, so as to achieve rapid splicing, installation and fixation. At the same time, the positioning groove 212 and the positioning block 214 are used together to reduce the shaking of the clamping part 205 and make it more stable.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In a preferred embodiment of this application, the sawing assembly 3 includes a first mounting plate 305, a second mounting plate 312, and a third mounting plate 315. The first mounting plate 305 is disposed in the middle section of the mounting cavity. A first drive shaft 307 and a second drive shaft 308 are respectively disposed at the left and right ends of the upper end face of the first mounting plate 305. The first drive shaft 307 and the second drive shaft 308 are connected by a drive belt 303. Two guide rails 313 are also disposed on both sides of the upper end face of the first mounting plate 305. Two sliders 31 are slidably disposed on the outer side of each guide rail 313. 4. The third mounting plate 315 is mounted on the upper end of the four sliders 314 and is located below the transmission belt 303. The third mounting plate 315 is connected to the transmission belt 303 through the buckle 316 set at the upper end. A telescopic cylinder 309 is set above the buckle 316. The second mounting plate 312 is mounted on the upper end of the telescopic cylinder 309. The upper end face of the second mounting plate 312 is provided with a third drive motor 310. The power output shaft of the third drive motor 310 is connected to the saw blade 304, and the saw blade 304 extends to the table 101 through the saw groove 102.

[0027] Furthermore, limit posts 311 are provided at the four top corners of the upper surface of the third mounting plate 315, and the upper ends of the limit posts 311 are inserted through and connected to the four top ends of the second mounting plate 312.

[0028] Furthermore, the sawing assembly 3 also includes a base plate 306 installed at the bottom of the mounting cavity. A second drive motor 301 is provided on the base plate 306. A drive belt 302 is connected to the outside of the power output shaft of the second drive motor 301. The other end of the drive belt 302 is connected to the outside of the first transmission shaft 307.

[0029] In this embodiment, the sawing assembly 3 operates as follows: The internal second drive motor 301 rotates, driving the drive belt 302 to rotate. The rotation of the drive belt 302 drives the first transmission shaft 307 to rotate, which in turn drives the outer transmission belt 303 to rotate. This causes the transmission belt 303 to move the buckle 316 and the third mounting plate 315. The buckle 316 and the third mounting plate 315 move along the guide rail 313, thus moving the saw blade 304. Simultaneously, the third drive motor 310 operates, driving the saw blade 304 to rotate, thereby moving the sawing edge. Simultaneously, the telescopic cylinder 309 can raise the height of the second mounting plate 312, the third drive motor 310, and the saw blade 304, controlling the height of the saw blade 304 extending out of the saw groove 102 to ensure that workpieces of different thicknesses can be cut. During the height raising of the second mounting plate 312, it will move according to the four limit posts 311 to achieve height movement and make the lifting more stable. The second drive motor 301 drives the drive belt 302 to drive the first transmission shaft 307 to rotate, which can ensure that the belt slips when there is great resistance during the sawing process, preventing the overload and damage of multiple drive motors.

[0030] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a protective cover 104 is provided on the upper surface of the table 101 at one end of the saw groove 102.

[0031] Furthermore, a control switch 103 is also provided on the upper surface of the platform 101 outside the protective cover 104, and the control switch 103 is electrically connected to the first drive motor 211, the second drive motor 301 and the third drive motor 310.

[0032] In practical applications, the protective cover 104 can protect the saw blade 304 when not cutting, preventing accidental damage and making it safer and more practical. The control switch 103 can control the first drive motor 211, the second drive motor 301 and the third drive motor 310, making operation convenient.

[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11As a preferred embodiment of this application, the clamping member 205 includes a receiving groove 9 opened on the inner side of the clamping member 205, a frame 8 slidably installed inside the receiving groove 9, and a strip 5 installed at the center of the upper end of the frame 8. A top groove 7 is opened at the top of the receiving groove 9, and an adjusting cylinder 4 is installed in the top groove 7. The strip 5 is inserted into the top groove 7, and the end of the adjusting cylinder 4 is connected to the end face of the strip 5. The inner side of the frame 8 is a hollow structure, and several partitions 12 are symmetrically arranged on both sides below the frame 8. A storage gap is formed between the partitions 12. A moving groove 10 is also opened on the upper end of the frame 8 corresponding to the storage gap. Two moving blocks 11 are slidably connected at both ends inside the moving groove 10. An extension block 6 is connected below each moving block 11. The extension block 6 can be stored in the storage gap. The molding strip 5 has symmetrical grooves 13 on both sides. Each groove 13 has an embedded groove 15 corresponding to the position of the moving groove 10. A spring block 17 and a rotating shaft 19 are slidably connected inside the embedded groove 15. One end of the spring block 17 away from the rotating shaft 19 is connected to one end of a spring 16. The other end of the spring 16 is connected inside the embedded groove 15. One end of a connecting rod 14 is rotatably connected to the outside of the rotating shaft 19. The other end of the connecting rod 14 is rotatably connected to the top of the moving block 11 inside the corresponding moving groove 10.

[0034] Furthermore, rollers 18 are sleeved on the lower end of the rebound block 17 and the lower end of the rotating shaft 19, and the rollers 18 rotate inside the inner groove 15. The top section of the extension block 6 extending to the outer part of the storage gap is a parallelogram, and the side near the clamping member 205 is a bevel.

[0035] This embodiment is implemented as follows: when the clamping component 2 fixes the workpiece in the previous step, the length of the clamping component 2 is only roughly set. When the workpiece enters the multiple clamping mechanisms inside the clamping component 2, it may not be parallel to the clamping member 205 in the clamping mechanism, but rather tilted. This results in the workpiece length being longer or shorter than the length of the clamping member 205 after the clamping member 205 comes together. At this time, the length of the clamping member 205 needs to be adjusted. During adjustment, the adjusting cylinder 4 pushes out the profile 5, which drives the profile frame 8 to move. After one end of the profile frame 8 moves to the outside of the clamping rod, the connecting rod 14 disengages from the top groove 7. At this time, the spring 16 releases its force and pushes out the return block 17. The return block 17 slides in the inner groove 15 and pushes the rotating shaft 19 to the end of the inner groove 15. During this process, the other end of the connecting rod 14 will push the moving block 11 to both ends of the moving groove 10, thus pushing out the extension block 6. After the extension block 6 is pushed out, it is parallel to the two sides of the non-adjustable part of the clamping member 205, thus achieving the clamping of the workpiece. It should be noted that the usage state of the clamping member 205 can be adjusted by the user. The clamping member 205 can be in the fully extended state when the workpiece is first roughly clamped, or it can be in the fully retracted state when the workpiece is first roughly clamped, depending on the length of the workpiece and the needs of the user.

[0036] When the clamping member 205 initially roughly clamps the workpiece in its fully extended state, subsequent adjustments are made to retract the excess portion of the clamping member 205. Retracting the clamping member 205 only requires adjusting the cylinder 4, which enables the overall movement of the extension block 6, the profile 5, and the frame 8. This ensures that the unretracted portion remains parallel to the sides of the non-adjustable portion of the clamping frame. Furthermore, the length of a single extension block 6 and its associated components can be customized to be smaller or larger, depending on the application scenario and the precision required for processing the workpiece.

[0037] Please see Figures 1 to 11 The present invention discloses a method for using a sawing device with an automatic control system, the method comprising the following steps: Step 1: Adjust the position of the clamping assembly 2 on the table 101 and the distance between each clamping mechanism inside the clamping assembly 2 to meet the edge cutting of workpieces of different widths. When placing the workpiece, the side to be cut should be on the saw groove 102. When adjusting, first slide the clamping assembly 2 to push the entire clamping assembly 2 on the protrusion 106 to adjust the size of the edge to be cut of the workpiece. Then adjust the spacing of the clamping mechanisms inside the clamping assembly 2. Step 2: During the clamping mechanism interval adjustment, the first drive motor 211 operates, driving the drive screw 217 to rotate, thereby rotating the active block 202. Since the active block 202 is slidably connected to the slide rod 204 on both sides, this restricts the rotation of the active block 202, allowing for its displacement. During the displacement of the active block 202, the auxiliary rod 209 connected to it moves accordingly. Simultaneously, the auxiliary rod 209 drives its respective connected rotating rod 203 to move. The rotating rod 203 rotates along with the rotating column 210, changing the angle between them, contracting or lengthening. The direction of movement of the active block 202 changes accordingly. At the same time, multiple rotating rods 203 will drive their respective connected driven blocks 206 to move during the movement. The driven block 206 closest to the first side plate 201 and the rotating rod 203 above it will drive the auxiliary rod 209 below the first side plate 201 to rotate outside the rotating column 210, thus limiting the maximum extension length. In this way, the spacing between multiple driven blocks 206 is adjusted. The driven blocks 206 are attached to the slide rod 204 for displacement. At the same time, the clamping mechanism on the side of the driven blocks 206 and the active block 202 follows the displacement to complete the spacing adjustment. Step 3: Place multiple workpieces requiring edge sawing on the table 101 in the gaps formed by multiple clamping mechanisms, ensuring that the side requiring sawing is outside the saw groove 102. Then, the first drive motor 211 works to drive the active block 202 and the driven block 206 to move closer together, so that the clamping parts 205 in the clamping mechanism move closer together. Subsequently, the clamping parts 205 work to fine-tune their length, extending outward or retracting inward, to ensure that the clamping parts 205 can completely fit against both sides of the workpiece. Step 4: The sawing assembly 3 operates, driven by the second drive motor 301, which drives the drive belt 302 to rotate. When the drive belt 302 rotates, it drives the first transmission shaft 307 to rotate. When the first transmission shaft 307 rotates, it drives the outer transmission belt 303 to rotate, thus moving the belt buckle 316 and the third mounting plate 315. The belt buckle 316 and the third mounting plate 315 move along the track of the guide rail 313, which in turn moves the saw blade 304. At the same time, the third drive motor 310 operates, driving the saw blade 304 to rotate, thus moving the sawing edge. In summary, this invention, by setting up a processing table, a clamping assembly, and a sawing assembly, firstly allows for easy adjustment of the sawing edge size by adjusting the distance between the clamping assembly and the saw groove, making operation convenient. Secondly, the multiple clamping mechanisms connected to the outside of the sawing assembly can be quickly disassembled and replaced, facilitating subsequent maintenance of the clamping components. Furthermore, the interval adjustment between the multiple sawing mechanisms is simple, allowing for the adjustment of multiple gaps in a single operation, satisfying the clamping and fixing of multiple workpieces of the same specification, and significantly improving efficiency.

9. The method of using the sawing device with an automatic control system according to claim 6, characterized in that, The method of use includes the following steps: Step 1: Adjust the position of the clamping assembly (2) on the table (101) and the distance between each clamping mechanism in the clamping assembly (2) to meet the edge cutting of workpieces of different widths. When placing, the side to be cut should be on the saw groove (102). When adjusting, first slide the clamping assembly (2) to push the entire clamping assembly (2) on the convex edge (106) to adjust the size of the edge to be cut of the workpiece, and then adjust the spacing of the clamping mechanisms inside the clamping assembly (2). Step 2: During the clamping mechanism interval adjustment, the first drive motor (211) operates, driving the drive screw (217) to rotate, thereby rotating the active block (202). Since the active block (202) is slidably connected to the slide rod (204) on both sides, the rotation of the active block (202) is restricted, thus achieving the displacement of the active block (202). During the displacement of the active block (202), the auxiliary rod (209) connected to it moves accordingly. At the same time, the auxiliary rod (209) drives the rotating rod (203) connected to it to move. The rotating rod (203) will rotate along with the rotating column (210), and the angle between the two rods changes, contracting or lengthening, which is controlled by the main... The moving direction of the moving block (202) changes accordingly. At the same time, multiple rotating rods (203) will drive their respective connected driven blocks (206) to move during the movement. The driven block (206) closest to the first side plate (201) and the rotating rod (203) above it will drive the auxiliary rod (209) below the first side plate (201) to rotate outside the rotating column (210) to limit the maximum expansion length. In this way, the spacing between multiple driven blocks (206) is adjusted. The driven block (206) is attached to the slide rod (204) for displacement. At the same time, the clamping mechanism on the side of the driven block (206) and the active block (202) follows the displacement to complete the spacing adjustment. Step 3: Place multiple workpieces requiring edge sawing on the table (101) in the gaps formed by multiple clamping mechanisms, ensuring that the side requiring edge sawing is outside the saw groove (102). Then, the first drive motor (211) works to drive the active block (202) and the driven block (206) to move closer together, so that the clamping parts (205) in the clamping mechanism move closer together. Then, the clamping parts (205) work to fine-tune their length, extending outward or retracting inward, to ensure that the clamping parts (205) are completely attached to both sides of the workpiece. Step 4: The saw edge assembly (3) works, driven by the second drive motor (301), which drives the drive belt (302) to rotate. When the drive belt (302) rotates, it drives the first transmission shaft (307) to rotate. When the first transmission shaft (307) rotates, it drives the outer transmission belt (303) to rotate, so that the transmission belt (303) drives the buckle (316) and the third mounting plate (315) to move. The buckle (316) and the third mounting plate (315) move along the track of the guide rail (313), driving the saw blade (304) to move. At the same time, the third drive motor (310) works, driving the saw blade (304) to rotate, thus moving the saw edge.
