Description

Technical Field

[0001] This utility model relates to the technical field of woodworking equipment, and in particular to a double-sided wood trim machine. Background Technology

[0002] In the wood processing process, wood trim machines in woodworking machinery are mainly used to process various decorative lines on wood and to process round bars.

[0003] Existing wood trimming machines mainly rely on the upper planer and pressure roller to adjust the height relative to the wood. The lower planer and conveyor roller are usually fixed in the wood trimming machine and can only rotate. However, the upper planer and pressure roller are both located in the same lifting device. The upper planer cannot be adjusted independently of the upper pressure roller, which reduces the adaptability of the wood trimming machine to different processing thicknesses and makes it unable to process wood trim of multiple specifications. Furthermore, the independent adjustment of the cutting depth and clamping force of the wood is limited, which reduces the control of cutting accuracy.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] This invention addresses the problem that existing wood trimming machines primarily rely on the upper planer and pressure roller for height adjustment relative to the wood. Since both the upper planer and pressure roller are located in the same lifting device, the upper planer cannot be independently adjusted for height, reducing the adaptability of the wood trimming machine to different processing thicknesses and making it incompatible with processing wood trimming of various specifications. Furthermore, the independent adjustment of the wood cutting depth and pressure is limited, reducing the control of cutting accuracy. This invention proposes a double-sided wood trimming machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A double-sided wood trimming machine, comprising: A machine base, wherein the machine base is provided with a conveying channel for linearly conveying workpieces; The first cutting mechanism includes a first lifting device disposed on the base and a first cutting blade connected to the first lifting device. The first cutting blade is used to process the top of the workpiece, and the first cutting blade is driven to move up and down on the upper side of the conveying channel by the first lifting device. The second cutting mechanism includes a second lifting device disposed on the base and a second cutting blade connected to the second lifting device. The second cutting blade is used to process the bottom of the workpiece. The second cutting blade is driven by the second lifting device to move up and down on the lower side of the conveying channel. Along the workpiece conveying direction of the conveying channel, the second cutting blade is located on one side of the first cutting blade.

[0007] As described above, in a double-sided wood trimming machine, along the workpiece conveying direction of the conveying channel, there is a preset distance between the rotation center of the first cutting blade and the rotation center of the second cutting blade, the preset distance being 3 to 5 centimeters.

[0008] As described above, in a double-sided wood trimming machine, the first cutting mechanism further includes a first bracket disposed between the first lifting device and the first cutting blade, and the second cutting mechanism further includes a second bracket disposed between the second lifting device and the second cutting blade. A first rotating device for driving the first cutting blade to rotate is provided between the first bracket and the first cutting blade, and a second rotating device for driving the second cutting blade to rotate is provided between the second bracket and the second cutting blade.

[0009] As described above, in a double-sided wood trimming machine, the first support includes a first vertical connecting section connected to the first lifting device and a first oblique connecting section disposed between the first vertical connecting section and the first rotating device; the second support includes a second vertical connecting section connected to the second lifting device and a second oblique connecting section disposed between the second vertical connecting section and the second rotating device.

[0010] As described above, in a double-sided wood trimming machine, the machine base is further provided with a first guide bracket for guiding the first vertical connecting section to rise and slide and a second guide bracket for guiding the second vertical connecting section to rise and slide. The first lifting device is located at the lower part of the first guide bracket, and the first vertical connecting section of the first bracket moves up and down relative to the first guide bracket through the first lifting device. The second lifting device is located at the lower part of the second guide bracket, and the second vertical connecting section of the second bracket moves up and down relative to the second guide bracket through the second lifting device.

[0011] As described above, in a double-sided wood trimming machine, the machine base is further provided with a chip discharge port at its top and a chip discharge channel on its inner side. The chip discharge channel is connected to the chip discharge port. The first cutting blade and the second cutting blade are respectively positioned close to the chip discharge port through the first inclined connecting section and the second inclined connecting section.

[0012] The double-sided wood trimming machine described above further includes a gantry frame mounted on the machine base, a third lifting device mounted on the gantry frame, and a planing mechanism and a conveying mechanism respectively mounted on the upper and lower sides of the conveying channel. The planing mechanism is connected to the third lifting device via a connecting bracket, and the connecting bracket is slidably mounted on the gantry frame. The third lifting device drives the connecting bracket to move up and down relative to the gantry frame, thereby driving the planing mechanism to move up and down relative to the conveying channel. The conveying channel is located between the planer and the conveying mechanism. The planer is located on one side of the first cutting mechanism, and the conveying mechanism is located on the machine base and on one side of the second cutting mechanism.

[0013] As described above, in a double-sided wood trimmer, the planing mechanism includes a first pressure roller group and a second pressure roller group respectively disposed on both sides of the first cutting blade. The first pressure roller group, the first cutting blade and the second pressure roller group are sequentially spaced along the workpiece conveying direction of the conveying channel. The first pressure roller group includes at least one rotatably disposed first pressure roller, and the second pressure roller group includes at least one rotatably disposed second pressure roller.

[0014] In the double-sided wood trimming machine described above, at least one of the first pressure rollers has a blade portion on its outer wall.

[0015] The double-sided wood trimming machine described above further includes a fine-tuning device connected to the planing mechanism, which drives the planing mechanism to move further up and down relative to the conveying channel; each of the first pressure rollers and each of the second pressure rollers is equipped with the fine-tuning device.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The first and second cutting blades are each independently equipped with a first lifting device and a second lifting device, respectively. This allows the first and second cutting blades to be independently adjusted in the vertical direction of the conveying channel. When processing wood trim of different thicknesses, the cutting depth at the top and bottom of the workpiece can be precisely adjusted separately. This improves the wood trim machine's adaptability to processing wood of different thicknesses and hardnesses, and helps to improve cutting accuracy and finished product qualification rate. It can also meet the processing needs of different wood trim shapes. In addition, by setting the first and second cutting blades separately, the collision caused by the upper and lower cutting blades penetrating the workpiece during processing can be avoided, which can ensure the smoothness and stability of wood trim processing and help improve the processing quality of wood trim.

The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figures 1 to 8As shown, this utility model provides a double-sided wood trimming machine, including a base 1, a first cutting mechanism 2, and a second cutting mechanism 3. The base 1 is provided with a conveying channel 11 for linearly conveying workpieces. The first cutting mechanism 2 includes a first lifting device 21 disposed on the base 1 and a first cutting blade 22 connected to the first lifting device 21. The first cutting blade 22 is used to process the top of the workpiece, and is driven by the first lifting device 21 to move up and down on the upper side of the conveying channel 11. The second cutting mechanism 3 includes a second lifting device 31 disposed on the base 1 and a second cutting blade 32 connected to the second lifting device 31. The second cutting blade 32 is used to process the bottom of the workpiece, and is driven by the second lifting device 31 to move up and down on the lower side of the conveying channel 11. Along the workpiece conveying direction of the conveying channel 11, the second cutting blade 32 is located on one side of the first cutting blade 22.

[0023] In this invention, the first cutting blade 22 and the second cutting blade 32 are independently equipped with a first lifting device 21 and a second lifting device 31, respectively. This allows the first cutting blade 22 and the second cutting blade 32 to be independently adjusted in the vertical direction of the conveying channel 11. When processing wood trim of different thicknesses, the cutting depth at the top and bottom of the workpiece can be precisely adjusted, improving the wood trim machine's adaptability to processing wood of different thicknesses and hardnesses. This also helps to improve cutting accuracy and finished product qualification rate, and can meet the processing needs of different wood trim shapes. In addition, by staggering the first cutting blade 22 and the second cutting blade 32, the collision caused by the upper and lower cutting blades penetrating the workpiece during processing can be avoided, ensuring the smoothness and stability of wood trim processing and improving the processing quality of the wood trim.

[0024] Furthermore, such as Figure 2 As shown, along the workpiece conveying direction of the conveying channel 11, there is a preset distance 4 between the rotation center of the first cutting blade 22 and the rotation center of the second cutting blade 32, the preset distance 4 being 3-5 cm. In this embodiment, by shortening the distance between the first cutting blade 22 and the second cutting blade 32, the workpiece can avoid elastic bending and bow-shaped vibration when processing wood thread, and can avoid the problem of deviation of the top and bottom surface contours and symmetry of the wood thread due to cumulative deformation of the workpiece during the feeding process. Furthermore, in this embodiment, the preset distance 4 is set to 3-5 cm, which, while ensuring sufficient chip removal and processing space, shortens the length of the free section of the workpiece during processing as much as possible, thereby reducing the deformation and vibration amplitude of the workpiece during the conveying process, making the cutting trajectory more stable, and thus improving the consistency of the wood thread processing dimensions and the quality of wood thread processing.

[0025] As some optional embodiments of this solution, the preset spacing 4 is the distance between the outer edge of the first cutting tool 22 and the outer edge of the second cutting tool 32. The preset spacing 4 can be set to 3 cm, 4 cm or 5 cm, etc.

[0026] As an optional embodiment of this solution, such as Figure 1 As shown, the first cutting mechanism 2 further includes a first bracket 23 disposed between the first lifting device 21 and the first cutting blade 22, and the second cutting mechanism 3 further includes a second bracket 33 disposed between the second lifting device 31 and the second cutting blade 32. A first rotating device 24 for driving the first cutting blade 22 to rotate is provided between the first bracket 23 and the first cutting blade 22, and a second rotating device 34 for driving the second cutting blade 32 to rotate is provided between the second bracket 33 and the second cutting blade 32. Specifically, the first lifting device 21 and the second lifting device 31 are respectively disposed in the machine base 1, and the first bracket 23 and the second bracket 33 are respectively disposed above the first lifting device 21 and the second lifting device 31. The first cutting blade 22 is connected to the first bracket 23 through the first rotating device 24, and the top of the first bracket 23 is obliquely disposed on the upper side of the conveying channel 11 so that the first cutting blade 22 can extend to the upper side of the conveying channel 11 to cut the top of the workpiece. In the cutting process, the second cutting blade 32 is mounted on the lower side of the conveying channel 11 via the second bracket 33. The first lifting device 21 and the second lifting device 31 drive the first cutting blade 22 and the second cutting blade 32 to move towards or away from the conveying channel 11, respectively, so as to realize independent control of the lifting of the first cutting blade 22 and the second cutting blade 32, which is beneficial to improve the accuracy of the lifting adjustment of the first cutting blade 22 and the second cutting blade 32. The first rotating device 24 and the second rotating device 34 drive the first cutting blade 22 and the second cutting blade 32 to rotate, respectively, to ensure the cutting of the wood workpiece. Secondly, the first lifting device 21 and the second lifting device 31 are both installed in the machine base 1, which is beneficial to assembly and subsequent maintenance. At the same time, by setting the first bracket 23 and the second bracket 33, the assembly flexibility of the first cutting blade 22, the second cutting blade 32, the first lifting device 21 and the second lifting device 31 can be improved, and it is convenient for the assembly personnel to adjust the installation distance between the first cutting blade 22 and the second cutting blade 32.

[0027] Optionally, the first rotating device 24 and the second rotating device 34 are respectively configured as rotating motors to realize high-speed rotation of the first cutting blade 22 and the second cutting blade 32.

[0028] As an optional embodiment of this solution, such as Figure 1As shown, the first support 23 includes a first vertical connecting section 231 connected to the first lifting device 21 and a first oblique connecting section 232 disposed between the first vertical connecting section 231 and the first rotating device 24. The second support 33 includes a second vertical connecting section 331 connected to the second lifting device 31 and a second oblique connecting section 332 disposed between the second vertical connecting section 331 and the second rotating device 34. In this embodiment, the first vertical connecting section 231 is connected to the lifting end of the first lifting device 21. The first oblique connecting section 232 extends obliquely from the top of the first vertical connecting section 231 and is disposed on the upper side of the conveying channel 11. The first cutting blade 22 is connected to the first oblique connecting section 232 and its blade axis extends in a direction perpendicular to the conveying channel 11. The first rotating device 24 is disposed between the blade axis of the first cutting blade 22 and the first oblique connecting section 232 to achieve high-speed rotation of the first cutting blade 22 through the first rotating device 24. Section 331 is connected to the lifting end of the second lifting device 31. The second oblique connecting section 332 extends obliquely from the top of the second vertical connecting section 331 and is disposed on the lower side of the conveying channel 11. The second cutting blade 32 is connected to the second oblique connecting section 332 and its blade shaft extends in a direction perpendicular to the conveying channel 11. The second rotating device 34 is provided between the blade shaft of the second cutting blade 32 and the second oblique connecting section 332 to achieve high-speed rotation of the second cutting blade 32 through the second rotating device 34. By providing the first oblique connecting section 232 and the second oblique connecting section 332 in the first bracket 23 and the second bracket 33, the assembly flexibility of the first cutting blade 22 and the second cutting blade 32 can be improved, ensuring that the first cutting blade 22 and the second cutting blade 32 are assembled at a preset distance 4. At the same time, the assembly flexibility of the first lifting device 21 and the second lifting device 31 in the machine base 1 can be improved, so that the first lifting device 21 and the second lifting device 31 can be staggered, which is beneficial to reducing the volume of the double-sided wood trimming machine.

[0029] Optionally, the first lifting device 21 and the second lifting device 31 can be configured as telescopic push rod type lifting devices or screw drive type lifting devices, which can simplify the structure of the first lifting device 21 and the second lifting device 31 and facilitate the assembly and maintenance of the wood trim machine.

[0030] As an optional embodiment of this solution, such as Figure 1As shown, the machine base 1 is further provided with a first guide bracket 25 for guiding the first vertical connecting section 231 to rise and slide, and a second guide bracket 35 for guiding the second vertical connecting section 331 to rise and slide. The first lifting device 21 is located at the lower part of the first guide bracket 25. The first vertical connecting section 231 of the first bracket 23 moves up and down relative to the first guide bracket 25 through the first lifting device 21. The second lifting device 31 is located at the lower part of the second guide bracket 35. The second vertical connecting section 331 of the second bracket 33 moves up and down relative to the second guide bracket 35 through the second lifting device 31. Specifically, the first guide bracket 25 and the second guide bracket 35 are respectively fixedly installed in the machine base 1, and the first guide bracket 25 and the second guide bracket 35 are respectively provided with a first guide cavity and a second guide cavity for the first vertical connecting section 231 and the second vertical connecting section 331 to rise and slide. This is beneficial to improving the stability of the rise and fall movement of the first bracket 23 and the second bracket 33, thereby improving the stability of the rise and fall movement of the first cutting blade 22 and the second cutting blade 32, and improving the reliability and safety of the double-sided wood trimming machine.

[0031] As another optional embodiment of this solution, such as Figure 1 As shown, the first lifting device 21 includes a first drive motor 211 mounted on the base 1, a first lead screw 212 connected to the first drive motor 211, and a first nut seat 213 slidably engaged with the outside of the first lead screw 212. The end of the first lead screw 212 away from the first drive motor 211 is connected to the first bracket 23, and the first nut seat 213 is connected to the first guide bracket 25. The first drive motor 211 drives the first lead screw 212 to rotate, and simultaneously, a meshing transmission occurs between the first lead screw 212 and the first nut seat 213 to drive the first bracket 23 to move up and down, thereby realizing the up and down movement of the first cutting blade 22 on the upper side of the conveying channel 11. The second lifting device 31 includes a second drive motor 311 disposed on the base 1, a second lead screw 312 connected to the second drive motor 311, and a second nut seat 313 slidably engaged with the outside of the second lead screw 312. One end of the second lead screw 312 away from the second drive motor 311 is connected to the second bracket 33, and the second nut seat 313 is connected to the second guide bracket 35. The second drive motor 311 drives the second lead screw 312 to rotate, and at the same time, the second lead screw 312 and the second nut seat 313 engage to drive the second bracket 33 to move up and down, thereby realizing the up and down movement of the second cutting blade 32 under the conveying channel 11.

[0032] As another optional embodiment of this solution, such as Figure 3As shown, the machine base 1 also has a chip discharge port 12 at its top and a chip discharge channel 13 on its inner side. The chip discharge channel 13 communicates with the chip discharge port 12. The first cutting tool 22 and the second cutting tool 32 are respectively disposed close to the chip discharge port 12 through the first inclined connecting section 232 and the second inclined connecting section 332. In this embodiment, the machine base 1 has a chip discharge channel 13 communicating with the chip discharge port 12, and the chip discharge channel 13 is inclined. The outlet end of the chip discharge channel 13 communicates with the outside through the side of the machine base 1, and the outlet of the chip discharge channel 13... The first cutting blade 22 and the second cutting blade 32 are positioned close to the chip discharge port 12, with the end lower than the chip discharge port 12. This embodiment optimizes the chip discharge path of the double-sided wood thread machine and ensures that the first cutting blade 22 and the second cutting blade 32 can reach the chip discharge port 12 by shortening the distance between them. This allows the wood chips and dust generated during wood thread processing to be uniformly drawn into the chip discharge port 12, preventing wood chips and dust from splashing everywhere and causing secondary pollution. This improves the cleanliness of the workshop environment and reduces the health risk of operators inhaling dust.

[0033] Furthermore, the chip removal channel 13 is provided with a clearance opening 131 for the second inclined connecting section 332 to pass through, and the clearance opening 131 extends along the lifting path of the second bracket 33 to ensure that the second cutting blade 32 extends to the lower part of the chip removal opening 12.

[0034] Further optional, such as Figure 2 As shown, the chip discharge port 12 is also provided with a third cutting edge 121 and a fourth cutting edge 122 on both sides; when the workpiece moves along the conveying channel 11, the first cutting tool 22, the second cutting tool 32, the third cutting edge 121 and the fourth cutting edge 122 can work together to process the workpiece into wood, which is beneficial to improving the diversity, flexibility and adaptability of wood processing.

[0035] Alternatively, the outer side of the first cutting tool 22 may also be provided with an upper chip box connected to the connecting bracket 16.

Further, the double-sided wood trim machine also includes a gantry frame 14 disposed on the machine base 1 and a third lifting device 15 disposed on the gantry frame 14. The gantry frame 14 is disposed on the upper part of the machine base 1, and the third lifting device 15 is disposed on the top of the gantry frame 14. A connecting bracket 16 is slidably disposed on the gantry frame 14 between the third lifting device 15 and the planing mechanism 5. The connecting bracket 16 is slidably disposed on the gantry frame 14. The connecting bracket 16 is mounted on two pairs of vertical supports on the gantry frame 14. The third lifting device 15 drives the connecting bracket 16 to move up and down relative to the gantry frame 14, thereby driving the planer mechanism 5 to move up and down relative to the conveying channel 11. In this embodiment, the planer mechanism 5 is independently equipped with the third lifting device 15 to realize the planer mechanism 5 to move up and down on the upper side of the conveying channel 11, which can adjust the spatial height of the conveying channel 11. At the same time, the first cutting blade 22 and the second cutting blade 32 are independently equipped with the first lifting device 21 and the second lifting device 31, respectively, to realize the independent lifting control of the first cutting blade 22 and the second cutting blade 32 on the upper and lower sides of the conveying channel 11. This is beneficial to improve the adaptability and flexibility of the double-sided wood trimming machine to different processing thicknesses, and to be compatible with processing multiple specifications of wood trimming. Moreover, the cutting depth and the clamping force of the wood can be independently adjusted, which improves the control of cutting accuracy.

[0037] Further optional, such as Figure 1 As shown, the third lifting device 15 includes a third drive motor 151 mounted on the gantry frame 14, a third lead screw 152 connected to the third drive motor 151, and a third nut seat 153 connected to the connecting bracket 16 and driven by the third lead screw 152. The third drive motor 151 drives the third lead screw 152 to rotate relative to the third nut seat 153, and the third nut seat 153 converts the rotation of the third lead screw 152 into lifting movement, so as to drive the planer mechanism 5 to lift and move through the connecting bracket 16.

Specifically, the first pressure roller group 51 is disposed near the entrance end of the conveying channel 11, and the second pressure roller group 52 is disposed near the exit end of the conveying channel 11. The first pressure roller group 51 includes three parallel sets of first pressure rollers 511, and each first pressure roller 511 has a cutting edge 512 on its outer side to perform cutting processing on the workpiece. The second pressure roller group 52 includes... Two sets of second pressure rollers 521 are arranged in parallel. The outer wall of the second pressure rollers 521 can be set to a smooth surface or a frosted surface. In actual application, the workpiece is driven to move along the conveying channel 11 by the conveying mechanism 6. At the same time, each of the first pressure rollers 511 rotates to cut the workpiece. The first cutting blade 22 and the second cutting blade 32 are moved to the preset processing position relative to the conveying channel 11 by the first lifting device 21 and the second lifting device 31, respectively. As the workpiece moves linearly along the conveying channel 11, the first pressure rollers 511, the first cutting blade 22, the second cutting blade 32, the third cutting blade and the fourth cutting blade cooperate to perform wood trimming on the workpiece. Subsequently, each of the second pressure rollers 521 is at the rear end of the conveying channel 11 to perform sanding and polishing on the workpiece. In addition, the rotational arrangement of each of the first pressure rollers 511 and each of the second pressure rollers 521 can assist in conveying the workpiece and ensure the movement and cutting of the workpiece.

[0040] Further optional, such as Figures 5 to 8As shown, the connecting bracket 16 is equipped with a driving device 9 for driving each of the first pressure rollers 511 and each of the second pressure rollers 521 to rotate. The driving device 9 includes a main drive motor 91 and a gear transmission mechanism 92 disposed between the main drive motor 91 and the planer mechanism 5.

[0043] As another optional embodiment of this solution, such as Figure 1As shown, the double-sided wood trimming machine also includes a fine-tuning device 7 connected to the planing mechanism 5. The fine-tuning device 7 drives the planing mechanism 5 to move further up and down relative to the conveying channel 11. Each of the first pressure rollers 511 and each of the second pressure rollers 521 is equipped with the fine-tuning device 7. Specifically, the fine-tuning device 7 is located on the connecting bracket 16. Each of the first pressure rollers 511 and each of the second pressure rollers 521 is connected to the connecting bracket 16 and the gear transmission mechanism 92 through the fine-tuning device 7. In practical applications, the third lifting device 15 drives each of the first pressure rollers 511 and each of the second pressure rollers 521 to descend to a preset position to ensure that each of the first pressure rollers 511 and each of the second pressure rollers 521 is in contact with the workpiece. When the workpiece moves along the conveying channel 11, each of the first pressure rollers 511 and each of the second pressure rollers 521 is successively subjected to the reaction force of the workpiece and rises through the fine-tuning device 7 to adapt to the height of the workpiece surface, further improving the pressing force and cutting accuracy of the planing mechanism 5 on the workpiece.

[0044] As an optional embodiment of the fine-tuning device 7, such as Figure 7 and Figure 8 As shown, any of the fine-tuning devices 7 includes an elastic adjustment module disposed between the rolling mechanism and the connecting bracket 16, and an adaptive linkage module 8 is provided between the planer mechanism 5 and the gear transmission mechanism 92; specifically, an adaptive linkage module 8 is provided between any of the third assembly brackets 513 and the corresponding second gear 9221, and an adaptive linkage module 8 is provided between any of the fourth assembly brackets 522 and the corresponding third gear 9231; an elastic adjustment module is provided between any of the third assembly brackets 513 and the connecting bracket 16, and an elastic adjustment module is provided between any of the fourth assembly brackets 522 and the connecting bracket 16; in practical applications, it can... The drive device 9 drives the adaptive linkage module 8 to rotate and its end to move up and down, thereby realizing the rotation and lifting movement of the pressure roller in the planer mechanism 5. When the workpiece moves through the conveying channel 11, the pressure roller is subjected to the reaction force of the workpiece and is further adjusted up and down relative to the conveying channel 11 through the elastic adjustment module to adapt to different surface heights of the workpiece, thereby improving the adaptability to wood thread processing, which helps to ensure the processing and protection of wood thread, and thus improves the processing quality of wood thread. In addition, each of the first pressure rollers 511 and each of the second pressure rollers 521 presses down and rotates to cut the workpiece by the rebound force of their respective elastic adjustment modules.

[0045] Further optionally, the adaptive linkage module 8 can be configured as a cam linkage module or an eccentric wheel linkage module, without specific limitations here.

[0046] Optionally, the elastic adjustment module includes a mounting shaft connected to the connecting bracket 16 and an elastic element disposed on the outside of the mounting shaft. The mounting shaft is provided between the third assembly bracket 513 and the connecting bracket 16, and between the fourth assembly bracket 522 and the connecting bracket 16. The elastic element is provided between the third assembly bracket 513 and the corresponding mounting shaft, and between the fourth assembly bracket 522 and the corresponding mounting shaft. When the workpiece moves along the conveying channel 11, the first pressure roller 511 or the second pressure roller 521 is subjected to the extrusion force of the workpiece and contracts through the elastic element to achieve fine adjustment of the working height of the first pressure roller 511 and the second pressure roller 521.
