In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please refer to Figures 1 to 10 This utility model provides a single-head tracking trimming machine for trimming sheet metal, including a translation device 1, a lifting device 2, a pushing device 3, a guiding device 4, and a trimming device 5. The lifting device 2 is mounted on the translation device 1, and the translation device 1 drives the lifting device 2 to move along the length direction of the sheet metal 6. The pushing device 3 is mounted on the lifting device 2, and the lifting device 2 drives the pushing device 3 to move along the thickness direction of the sheet metal 6. The trimming device 5 is mounted on the pushing device 3, and the pushing device 3 drives the trimming device 5 to move along the width direction of the sheet metal 6. The guiding device 4 includes a transverse guide frame 41 and a guide bar 42. The transverse guide frame 41 is connected to the lifting device 2, and the guide bar 42 is configured to cooperate with the trimming device 5.

[0030] In the embodiments of this utility model, the translation device 1, the lifting device 2, and the propulsion device 3 respectively drive the trimming device 5 to move in different directions. Specifically, the translation device 1 drives the lifting device 2 to move along the length direction of the board 6, which can cover the trimming needs of boards 6 of different lengths and can perform horizontal trimming along the length direction of the board 6. The lifting device 2 drives the propulsion device 3 to move along the thickness direction of the board 6, which can adjust the height of the trimming device 5 according to the thickness of the board 6. Whether it is a thin board 6 or a thick board 6, it can ensure precise contact between the trimming cutter and the edge of the board 6, and realize vertical lifting and lowering trimming along the thickness direction of the board 6. The propulsion device 3 drives the trimming device 5 to move along the width direction of the board 6, which can flexibly adjust the trimming range and adapt to the edge processing of boards 6 of different widths, and can efficiently and accurately control the trimming range. Through the above structural settings, the translation device 1, the lifting device 2, and the propulsion device 3 realize the multi-dimensional movement of the trimming device 5, which has high adaptability to different specifications of boards 6 and strong flexibility.

[0031] In addition, this embodiment also includes a guide device 4 to improve the stability and accuracy of trimming. The transverse guide frame 41 is connected to the lifting device 2 to provide a transverse positioning reference for the trimming device 5, ensuring the straightness of the trimming trajectory. The support bar 42 works in conjunction with the trimming device 5 and is located below the board 6 to provide support for the bottom of the trimming device 5, preventing the trimming device 5 from deviating due to its own weight. The support bar 42 allows the trimming device 5 to always move along the preset path of the edge of the board 6, which is especially suitable for cases where the edge of the board 6 is irregular. It can effectively correct edge errors and improve the flatness of the edge after trimming.

[0032] It should be noted that the guide device 4 in this embodiment is installed on the frame of the sheet metal trimming equipment. Since other components of the sheet metal trimming equipment are not shown in the accompanying drawings, the guide device 4 is depicted as suspended. In actual installation, the guide device 4 can be installed at a suitable location based on the equipment layout. Simply connecting the guide device 4 to the equipment or frame on the production site will achieve the guiding effect. Furthermore, the conveying of the sheet metal 6 is handled by the sheet metal conveying equipment. The sheet metal 6 shown in the accompanying drawings is a partial schematic diagram of the entire sheet metal 6, used to illustrate the working process of this embodiment.

[0033] Compared to multi-head trimming machines, the single trimming device 5 in this embodiment is more suitable for fine and targeted trimming of the sheet material 6. When faced with sheet material 6 of special shape or situations where local edges need to be trimmed, the single-head trimming device 5 can concentrate power and control precision, avoiding the cumulative errors caused by improper coordination of multiple heads. It is especially suitable for trimming small to medium batches of sheet material 6 of various specifications, offering greater flexibility. At the same time, the compact structure of each device in this embodiment saves installation space, and the clear transmission relationship between each device reduces the difficulty of operation and facilitates individual inspection or replacement of each component later, reducing maintenance costs and downtime.

[0034] The following describes the working process of this embodiment using the bottom of plate 6 as the starting point for processing. In actual production, the top, side, or any other position of plate 6 can also be used as the starting point for processing:

[0035] First, the board 6 to be trimmed is placed in the work area. After starting the equipment, the pushing device 3 pushes out the trimming device 5. At this time, the trimming device 5 contacts the board 6 and trims the board 6. The translation device 1 drives the connected lifting device 2 to move along the length direction of the board 6, so that the trimming device 5 follows the length direction of the board 6 and gradually advances to trim the bottom horizontal edge of the board 6. After the bottom horizontal edge is trimmed and reaches the rear end of the board 6, the translation device 1 stops, and the lifting device 2 starts and drives the pushing device 3 and the trimming device 5 to lift along the thickness direction of the board 6. During the lifting process, the trimming device 5 trims the rear end of the board 6. The vertical edge is trimmed; after the vertical edge at the rear end is trimmed, the lifting device 2 stops, the translation device 1 starts again and drives the trimming device 5 to move in the opposite direction to the first translation. During the movement, the trimming device 5 trims the horizontal edge at the top of the board 6; after the top horizontal edge is trimmed and reaches the front end of the board 6, the translation device 1 stops, the lifting device 2 starts again and drives the pushing device 3 and the trimming device 5 to descend along the thickness direction of the board 6. During the descent, the trimming device 5 trims the vertical edge at the front end of the board 6; after the trimming is completed, the pushing device 3 drives the trimming device 5 to retract, waiting for the next trimming.

[0036] With the above-mentioned structural configuration, the trimming device 5, driven by the translation device 1, the lifting device 2 and the propulsion device 3, can perform tracking and circling trimming around one side of the board 6 under the guidance of the guide device 4, achieving high precision, high stability and high flexibility in trimming the board 6, and effectively meeting the edge processing needs of the board 6 under different specifications and working conditions.

[0037] Preferably, the translation device 1 includes a base 101, a pair of transverse guide rods 102, a base plate 103, and a first cylinder 104; the pair of transverse guide rods 102 are arranged parallel to each other on the base 101, and a plurality of first sliders 105 are slidably provided on the transverse guide rods 102; the base plate 103 is connected to the first sliders 105; a connecting block 106 is provided on the side of the base plate 103; the cylinder body of the first cylinder 104 is connected to the base 101, and its piston rod is provided with a connecting head 107, a conical spacer 108, and a first cylinder 104. A buffer spring 109 and a second buffer spring 110 are provided; a flat spacer 111 is provided on the connector 107, one end of the connector 107 is connected to the piston rod of the cylinder, and the other end is connected to the connecting block 106; a conical spacer 108 is slidably sleeved on the piston rod of the cylinder, one end of the first buffer spring is connected to the conical spacer 108, and the other end abuts against the base 101; one end of the second buffer spring is connected to the conical spacer 108, and the other end is connected to the flat spacer 111.

[0038] In this embodiment, a pair of transverse guide rods 102 are arranged parallel to each other on the base 101, providing a stable guiding reference for the movement of the base plate 103. Several slidable first sliders 105 are connected to the base plate 103, allowing the base plate 103 to slide smoothly along the transverse guide rods 102, reducing swaying or offset during translation, and ensuring the accuracy of the trajectory of the lifting device 2 and subsequent trimming-related devices when moving along the length of the plate 6, laying the foundation for trimming accuracy. The piston rod of the first cylinder 104 is provided with a conical spacer 108, a first buffer spring 109, and a second buffer spring 110, forming a double buffering mechanism. When the piston rod drives the base plate 103 to the end of its stroke or encounters sudden resistance, the first buffer spring 109 can alleviate the impact force from the direction of the base 101 by abutting against the base 101; the second buffer spring 110 connects the conical spacer 108 and the flat spacer 111, and can buffer the force between the piston rod and the connecting block 106. This design effectively reduces rigid collisions during device operation, lowers wear on components, extends equipment lifespan, and avoids trimming deviations caused by impacts. One end of connector 107 is connected to the cylinder piston rod, and the other end is connected to the base plate 103 via connecting block 106. Combined with the flat spacer 111, this stabilizes the piston rod's power, ensuring smooth movement of the base plate 103 on the transverse smooth rod 102, strong buffering performance, and improved stability during the trimming process.

[0039] Preferably, the lifting device 2 includes a lifting seat 201, a buffer plate 202, a lifting plate 203, a second cylinder 204, and a buffer 205; the bottom of the lifting seat 201 is connected to the translation device 1, and the lifting plate 203 is slidably disposed on the lifting seat 201; the second cylinder 204 is disposed on the top of the lifting seat 201, and its piston rod is connected to the buffer plate 202; one end of the buffer 205 is connected to the top of the lifting seat 201, and the other end is connected to the buffer plate 202; the buffer plate 202 is connected to the lifting plate 203; and the trimming device 5 is installed on the lifting plate 203. In this embodiment, the lifting plate 203 is slidably disposed on the lifting seat 201, and can form a structure that can slide up and down by means of a sliding block, a guide rail, or other sliding structure, so as to ensure that the lifting plate 203 moves vertically along a preset trajectory during the lifting process and avoids positional deviation caused by shaking. The second cylinder 204 serves as the power source, with its piston rod connected to the buffer plate 202. The buffer plate 202 is then connected to the lifting plate 203, forming a continuous power transmission path. This ensures that the driving force of the second cylinder 204 is smoothly transmitted to the lifting plate 203 through the buffer plate 202, guaranteeing rapid lifting response and precise movement of the lifting plate 203. This ensures that the trimming tool maintains optimal contact with the edge of the sheet material 6, guaranteeing trimming accuracy. To reduce the impact during lifting, this embodiment includes a buffer 205. The buffer 205 can be a rubber damper, spring damper, air damper, or other damping mechanism with buffering and vibration reduction effects. In this embodiment, one end of the buffer 205 is connected to the top of the lifting seat 201, and the other end is connected to the buffer plate 202. The buffer plate 202 is also connected to the lifting plate 203, forming an effective buffering mechanism. When the second cylinder 204 drives the lifting plate 203 to rapidly rise and fall to its limit position or encounters sudden resistance, the buffer 205 absorbs the impact force, reducing the rigid collision between the lifting plate 203 and the lifting seat 201. Simultaneously, the buffer plate 202 disperses the direct impact of the cylinder's driving force on the lifting plate 203, protecting the trimming device 5 and the sheet metal 6 from severe vibration, extending the service life of equipment components, and reducing trimming errors caused by impact. Furthermore, the buffer 205 provides support for the buffer plate 202, making the second cylinder 204 more stable in maintaining the vertical position of the trimming device 5.

[0040] Preferably, the lifting seat 201 includes an upper connecting plate 2011, a lower connecting plate 2012, and a pair of vertical guide rods 2013. The pair of vertical guide rods 2013 are arranged parallel to each other between the upper connecting plate 2011 and the lower connecting plate 2012. A plurality of second sliders 2014 are slidably provided on each vertical guide rod 2013. The lifting plate 203 is connected to the second sliders 2014. The second cylinder 204 and the buffer 205 are respectively connected to the upper connecting plate 2011. In this embodiment, the pair of parallel vertical guide rods 2013, the upper connecting plate 2011, and the lower connecting plate 2012 form a rigid frame. The second sliders 2014 drive the lifting plate 203 to slide along the vertical guide rods 2013, which can effectively control the vertical trajectory, reduce deviation, and ensure trimming positioning accuracy. The frame structure has high overall rigidity, can stably bear the weight of the lifting plate 203 and related devices, reduce deformation, and adapt to high-intensity operations. The second cylinder 204 and the buffer 205 are installed on the upper connecting plate 2011. Power and buffer force are transmitted along the axial direction of the vertical light rod 2013, which improves the stability of lifting and facilitating component maintenance.

[0041] Preferably, the lifting seat 201 further includes a pair of vertical guide rods 2015, which are respectively disposed between the upper connecting plate 2011 and the lower connecting plate 2012; a plurality of third sliders 2016 are slidably provided on the vertical guide rods 2015; the transverse guide frame 41 includes a guide vertical plate 411, a guide block 412, a guide wheel 413, a guide bracket 414, and a proximity switch 415; the third sliders 2016 are connected to the guide vertical plate 411; the top of the guide vertical plate 411 is provided with a limit. Support angle 416, the limiting support angle 416 is elastically connected to the buffer plate 202; the guide block 412 is disposed on the guide vertical plate 411, and the guide wheel 413 is rotatably disposed on the guide block 412; the guide bracket 414 is provided with a connecting part 4141 and a transverse groove 4142, and the guide wheel 413 is slidably fitted into the transverse groove 4142; the proximity switch 415 is disposed on the guide vertical plate 411, and the lifting plate 203 is provided with a detection plate 206 that cooperates with the proximity switch 415.

[0042] In this embodiment, a pair of vertical guide rods 2015 cooperate with a third slider 2016 to provide a vertical sliding track for the guide plate 411 of the transverse guide frame 41. Combined with the guiding effect of the original vertical guide rods 2013, a dual vertical guiding system is formed, which greatly improves the verticality of the guide plate 411 and reduces lateral offset. The guide wheel 413 slides within the transverse groove 4142 of the guide bracket 414. When the lifting plate 203 adjusts its height, the elastic connection between the limiting support 416 and the buffer plate 202 provides a certain degree of relative motion freedom. Therefore, the guide wheel 413 does not need to disengage from the transverse groove 4142 throughout the trimming process and remains in a cooperative working state. This makes the lateral movement trajectory of the guide plate 411 and the proximity switch 415 installed on the guide plate 411 more accurate. In this embodiment, the guide bracket 414 is fixedly installed and can be mounted on the frame of the trimming equipment or other fixed equipment on the production site to provide a stable guide. The cooperation between the guide bracket 414, guide wheel 413, guide block 412 and guide vertical plate 411 keeps the horizontal position of the guide vertical plate 411 stable. The guide vertical plate 411 provides a certain support for the buffer plate 202 through the elastic connection between the limiting support angle 416 and the buffer plate 202. When it cooperates with the buffer 205, it can offset part of the gravity influence of the trimming device 5, making it easier and more stable to lift and maintain the position of the second cylinder 204.

[0043] With the above structural configuration, in this embodiment, during lateral guidance, the detection plate 206, in conjunction with the proximity switch 415, can monitor the relative position of the lifting plate 203 and the guide vertical plate 411, thereby ensuring that the second cylinder 204 lifts the trimming device 5 to the designated position. When the second cylinder 204 drives the trimming device 5 to descend, precise positioning is achieved through the cooperation of the guide bar 42 and the trimming device 5. The cooperation between the proximity switch 415 and the detection plate 206 can trigger a stop or warning when the lifting plate 203 moves beyond the preset range, preventing damage from component collisions. Simultaneously, the cooperation of both can provide feedback signals for the coordinated operation of each device, achieving automated and precise control.

[0044] Preferably, the buffer plate 202 is provided with a first buffer sleeve 417, and the lower part of the lifting seat 201 is provided with a second buffer sleeve 418. The limiting support angle 416 is connected to the first buffer sleeve 417 and is connected to the buffer plate 202 through the first buffer sleeve 417. The first buffer sleeve 417 and the second buffer sleeve 418 are arranged opposite to each other. The first buffer sleeve 417 and the buffer 205 are respectively provided on both sides of the second cylinder 204. In this embodiment, the elastic connection between the limiting support angle 416 and the buffer plate 202 is achieved through the first buffer sleeve 417, while the lower second buffer sleeve 418 can provide cushioning when the upper buffer plate 202 descends rapidly, improving the stability of the descent. In addition, the first buffer sleeve 417 and the buffer 205 are respectively located on both sides of the second cylinder 204, that is, respectively connected to both ends of the buffer plate 202. The two work together with the second cylinder 204 to act on the buffer plate 202, which can provide support for the lifting plate 203 and the connecting equipment below the buffer plate 202.

[0045] It should be noted that the first buffer sleeve 417 and the second buffer sleeve 418 in this embodiment are both mechanical components, which are usually used to absorb and reduce vibration, impact and noise in mechanical systems. As an elastic connecting element, it plays a key role in the transmission system, effectively reducing the dynamic load transmitted to the connected equipment, protecting the mechanical equipment from damage and extending its service life.

[0046] Preferably, the propulsion device 3 includes a fixed base 301, a sliding frame 302, a third cylinder 303, a motor plate 304, a sliding plate 305, and a position adjusting screw 306; the fixed base 301 is connected to the lifting device 2, and the sliding frame 302 is slidably connected to the fixed base 301; the third cylinder 303 is disposed on the sliding frame 302, and its piston rod is connected to the fixed base 301; the motor plate 304 is connected to the sliding frame 302 and has a sliding groove 304a; the sliding plate 305 is slidably disposed on the sliding groove 304a; the position adjusting screw 306 is rotatably disposed on the motor plate 304 and threadedly connected to the sliding plate 305; and the trimming device 5 is disposed on the sliding plate 305.

[0047] In this embodiment, the fixed base 301 is connected to the lifting device 2 and moves up and down under the drive of the lifting device 2. The fixed base 301 and the sliding frame 302 are slidably connected. The slidable connection can be achieved by a slider, a guide rail, or other sliding structure, forming a structure that can move horizontally. The third cylinder 303 is fixedly mounted on the sliding frame 302, and the piston rod of the cylinder is connected to the fixed base 301. When the piston rod of the third cylinder 303 extends, the piston rod acts on the fixed base 301. Since the position of the fixed base 301 remains relatively fixed, the piston rod reacts to the third cylinder 303 and the sliding frame 302, causing the sliding frame 302 to move in the opposite direction of the piston rod extension. The translation of the sliding frame 302 and the components mounted on the sliding frame 302 can be achieved by the action of the third cylinder 303. To more precisely adjust the position of the trimming mechanism, this embodiment provides a groove 304a on the motor plate 304, and a slide plate 305 is slidably mounted on the groove 304a. Furthermore, a baffle can be provided to prevent the slide plate 305 from falling off, thus avoiding baffle misalignment that could affect the processing accuracy of the trimming mechanism. Fine-tuning is achieved using a lead screw mechanism. A position adjusting lead screw 306 is rotatably mounted on the motor plate 304, and its end is threadedly connected to the slide plate 305. When the position adjusting lead screw 306 rotates, it moves the slide plate 305. The operator only needs to rotate the position adjusting lead screw 306 to adjust the position of the trimming mechanism.

[0048] Preferably, the sliding frame 302 is provided with a first digital display 307, the first digital display 307 is provided with a pressure adjusting screw 308, and the outer end of the pressure adjusting screw 308 is provided with a first handwheel 309; the motor plate 304 is provided with a second digital display 310, the position adjusting screw 306 is threadedly connected to the second digital display 310, and the outer end of the position adjusting screw 306 is provided with a second handwheel 311. In this embodiment, by setting the pressure adjusting screw 308, the extension length can be controlled when the pressure adjusting screw 308 is rotated. When the piston rod of the third cylinder 303 extends, the trimming mechanism retracts as a whole and separates from the plate 6; when the piston rod retracts, the trimming mechanism gradually approaches the plate 6 and trims the plate 6. When the piston rod retracts to a certain extent, the end of the position adjusting screw 306 contacts the fixed seat 301, preventing the piston rod from retracting further. At this point, the trimming mechanism stops at the preset position and stops advancing, thereby precisely controlling the advancing depth of the trimming mechanism. Under the action of the third cylinder 303 and the position adjusting screw 306, the trimming mechanism can maintain a stable output, thereby improving the accuracy of the trimming process.

[0049] Preferably, the trimming device 5 includes a trimming motor 501, a trimming cutter head 502, a tracking component 503, and a template component 504; the trimming motor 501 is connected to the motor plate 304; the trimming cutter head 502 is mounted on the output shaft of the trimming motor 501; the tracking component 503 includes a tracking roller 5031, a ball bearing 5032, and a tracking ring 5033; the tracking roller 5031 is connected to the output shaft of the trimming motor 501 via the ball bearing 5032. The tracking ring 5033 is sleeved on the tracking roller 5031, and the tracking roller 5031 has tracking contour plates 5034 on both sides of its front end; the template assembly 504 includes a template mounting block 5041, a template inner ring 5042, and a template outer ring 5043; the template mounting block 5041 is connected to the motor plate 304, the template inner ring 5042 is mounted on the template mounting block 5041, and the template outer ring 5043 is connected to the template inner ring 5042 by bolts.

[0050] In this embodiment, the trimming motor 501 drives the trimming cutter head 502 to rotate, and the trimming cutter head 502 is used to process the sheet material 6. The tracking component 503 is located in front of the trimming cutter head 502, and its function is to provide guidance for the movement of the trimming cutter head 502, so that the trimming cutter head 502 can better contact the sheet material 6 and avoid the problem of poor consistency caused by deviation during processing. Specifically, the tracking roller 5031 is connected to the output shaft of the trimming motor 501 through the ball bearing 5032, so that the tracking ring 5033 mounted on the tracking roller 5031 can rotate freely. During operation, the tracking ring 5033 is in close contact with the guide strip 42 or the sheet material 6, ensuring that the distance between the trimming cutter head 502 and the sheet material 6 remains consistent, thus improving the consistency of trimming. The tracking roller 5031 is connected to the output shaft of the trimming motor 501 via ball bearings 5032, allowing for flexible rotation. The tracking profile plates 5034 on both sides of its front end can closely conform to the top surface of the guide strip 42 or the top edge of the plate 6, moving synchronously with the shape of the plate 6. This design allows the trimming cutter head 502 to "follow" the workpiece to be trimmed via the guide of the tracking roller 5031, ensuring the cutter head is always precisely aligned with the trimming path and reducing manual alignment errors. The connection between the tracking roller 5031 and the motor output shaft via ball bearings 5032 not only reduces frictional loss during rotation but also buffers minor vibrations during the trimming process, making the contact movement of the tracking roller 5031 smoother and indirectly improving the cutting stability of the trimming cutter head 502, avoiding defects such as tool marks and burrs. The profile plates on both sides of the tracking roller 5031 can be designed with different angles or curvatures to adapt to various shapes such as flat edges, folded edges, and curved surfaces of the workpiece, expanding the applicability of the trimming device 5.

[0051] In this embodiment, the template assembly 504 allows the sheet metal 6 to be close to the trimming cutter head 502. The template mounting block 5041 is used to install the template inner ring 5042 and ensures that the template inner ring 5042 and template outer ring 5043 are aligned with the movement direction of the trimming mechanism. The template outer ring 5043 has multiple screw holes, which can be bolted to the template inner ring 5042 (bolts are not shown in the accompanying drawings; in actual installation, bolts of the appropriate specifications or lengths can be selected as needed). Bolt installation can also control the distance between the template inner ring 5042 and template outer ring 5043, allowing adjustment of the edge-adjusting position of the sheet metal 6. Furthermore, the contour of the template outer ring 5043 can be changed or adjusted according to the workpiece shape. During trimming, the tracking assembly 503 moves along the preset contour of the template outer ring 5043, providing a rigid guiding reference for the cutter head, ensuring the consistency of trimming dimensions for batch workpieces, and avoiding accuracy deviations caused by individual workpiece differences. The inner ring 5042 of the template is rigidly connected to the mounting block, and the outer ring is fastened with bolts. The overall structure is stable and is not prone to deformation or displacement when the tracking component 503 contacts the template, ensuring the reliability of the guiding reference. The outer ring 5043 of the template is connected to the inner ring with bolts, which is easy to disassemble. The outer ring 5043 of the template can be quickly replaced with the corresponding contour according to the trimming requirements of different workpieces without adjusting the core structure of the entire device, which greatly improves the adaptability of the equipment to multi-variety, small-batch production.

[0052] During operation, the plate 6 is placed against the outer ring 5043 of the template, and the trimming motor 501 starts, driving the trimming cutter head 502 to rotate. The trimming motor 501 is moved by the third cylinder 303 and its related adjustment structure, so that the front tracking component 503 is in contact with the top surface of the guide strip 42 or the plate 6. When the device is advanced, the tracking guide wheel 5031 rotates flexibly through the ball bearing 5032, and the tracking profile plate 5034 is synchronously guided along the contour of the guide strip 42 or the plate 6. The trimming cutter head 502 cuts and trims the edge of the workpiece according to the guide trajectory. After the trimming is completed, the motor stops, the device resets and repeats the operation.

[0053] Preferably, the support strip 42 is configured to cooperate with the tracking roller 5031. When the trimming cutter head 502 processes the bottom of the sheet 6, the tracking roller 5031 and the tracking contour plate 5034 abut against the top surface of the support strip 42. In this embodiment, the support strip 42 cooperates with the tracking roller 5031. When processing the bottom of the sheet 6, the tracking roller 5031 and the contour plate abut against the top surface of the support strip 42, which not only provides stable support for the trimming cutter head 502, but also achieves precise guidance through close contact, ensuring the stability and accuracy of the bottom trimming.

[0054] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a translation device, a lifting device, and a propulsion device, and placing the trimming device on the propulsion device, the combined movement of these three axes allows the trimming device to move precisely in three-dimensional space, thereby completing the trimming along the length, width, and thickness directions of the board without separate processing or rotation of the board, resulting in high processing efficiency; the transmission path of this utility model is clear, and the mechanical structure is compact; compared with multi-head trimming equipment, the design of a single trimming device reduces the risk of mechanical interference, and the core working components are concentrated, making daily maintenance simpler and reducing operation and maintenance costs.
