[0002] Plywood is a type of board made by bonding three or more layers of veneers together with adhesives. Due to its structural characteristics, plywood has advantages such as minimal deformation, low shrinkage, and a smooth surface. During manufacturing, the grain direction of each veneer layer is usually perpendicular to each other. This crisscrossing arrangement results in minimal differences in the physical and mechanical properties of the plywood. Common types of plywood include three-ply and five-ply boards.

[0003] According to announcement number CN222874821, an automatic plywood trimming machine includes a plywood cutting table. Symmetrically arranged upper support plates are mounted on the cutting table. Sliding supports are located on the sides of the upper support plates.

A second motor is fixedly mounted on the upper side of the top seat. A cutting blade is fixedly mounted on the output end of the second motor. A cleaning component is provided on the upper support plate. The cleaning component includes a long groove, with sealing heads installed at both ends of the long groove. A receiving pipe is provided on the outside of the sealing heads. This invention is reasonably designed. Through the cleaning component, the material generated during plywood trimming is automatically collected into a collection trough by a suction pump, maintaining the cleanliness of the plywood cutting table surface. No manual cleaning is required, avoiding pollution of the workshop air by debris.

[0004] The above-mentioned device eliminates the need for manual cleaning by setting up cleaning components, thus avoiding the pollution of workshop air by debris. According to the instruction manual and the attached drawings, the top of the upper support plate of the device is symmetrically connected with studs by threads. However, the plywood is of different sizes, and the threaded connection makes it impossible to adjust the studs according to the size of the plywood, resulting in certain limitations in its use. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device does not require manual cleaning by setting up a cleaning component, thus avoiding the pollution of workshop air by debris. According to the description and drawings, the top of the upper support plate of the device is symmetrically connected with studs by threads. However, the size of plywood is different, and the threaded connection makes it impossible to adjust the studs according to the size of the plywood, resulting in certain limitations in use. Therefore, this utility model provides an automatic plywood trimming machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic plywood trimming machine, comprising a cutting table and plywood, an upper support plate at the top of the cutting table, and cutting components symmetrically arranged at the top of the cutting table. A long groove is provided in the middle of the cutting components and the upper support plate. A through groove is opened at one end of the long groove, and an adjusting block is slidably connected inside the through groove. A pressing block is threadedly connected to one end of the adjusting block. A groove is opened inside the adjusting block, and a limit block is slidably connected inside the groove. A return spring is fixedly installed inside the groove, and one end of the return spring is fixedly installed to the top of the limit block. Limit grooves are symmetrically opened inside the through groove, and the limit block is adapted to the limit groove. A lifting block is slidably connected to one end of the adjusting block, and the lifting block passes through the groove and is fixedly installed to the limit block.

[0007] As a further improvement of this utility model: a sliding groove is provided inside the through groove, and a slider is fixedly installed at one end of the adjusting block, and the slider is adapted to the sliding groove.

[0008] As a further embodiment of this utility model: one end of the clamping block is rotatably connected to a half gear, and one end of the half gear is fixedly installed with a clamping rod. A rubber block is fixedly installed at the bottom end of the clamping rod, and an adjusting rack is slidably connected to the middle of the clamping block, and the adjusting rack is meshed with the half gear.

[0009] As a further embodiment of this utility model: a fixing block is fixedly installed at one end of the clamping block, and the top of the adjusting rack is symmetrically provided with insertion holes, and an insertion rod is inserted into the top of the adjusting rack, the insertion rod being adapted to the insertion hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model can quickly unlock and lock the adjusting block by raising or releasing the lifting block and using the linkage between the limiting block and the return spring. The operation is simple. The matching design of the slider and the slide groove ensures that the adjusting block slides smoothly and can flexibly adjust the position according to the size of the plywood. After the adjustment is completed, the limiting block automatically snaps into the limiting groove to fix it, ensuring stability. This effectively improves the adaptability of the trimming machine to plywood of different sizes, which not only meets the diverse processing needs, but also simplifies the operation process and improves work efficiency and equipment flexibility.

[0014] This invention converts linear motion into a downward rotating action of the clamping rod by driving the adjusting rack to rotate the half gear. Combined with a rubber block to increase friction, this ensures a tight fixation of the plywood. The limiting combination of the insertion rod and the insertion hole effectively prevents the clamping rod from loosening and rebounding, enhancing the reliability of the fixation. The flexible position adjustment function of the adjusting block allows it to adapt to plywood of different sizes and provides stable support during cutting. It also reduces the complexity of threaded clamping operations and makes clamping the plywood quick and easy. Attached Figure Description

[0023] Reference Figures 1 to 5 In this embodiment of the present invention, an automatic plywood trimming machine includes a cutting table 1 and a plywood 6. A top support plate 2 is provided at the top of the cutting table 1, and cutting components 4 are symmetrically arranged at the top of the cutting table 1. A long groove 5 is provided in the middle of the cutting components 4 and the top support plate 2. A through groove 7 is opened at one end of the long groove 5, and an adjusting block 9 is slidably connected inside the through groove 7. A pressing block 16 is threadedly connected to one end of the adjusting block 9. A groove 10 is opened inside the adjusting block 9, and a limiting block 11 is slidably connected inside the groove 10. A return spring 12 is fixedly installed inside the groove 10, and one end of the return spring 12 is fixedly installed at the top of the limiting block 11. Limiting grooves 8 are symmetrically opened inside the through groove 7, and the limiting block 11 is adapted to the limiting groove 8. A lifting block 13 is slidably connected to one end of the adjusting block 9, and the lifting block 13 passes through the groove 10 and is fixedly installed with the limiting block 11.

[0024] The above-mentioned scheme is adopted: the cutting table 1 and the cutting component 4 are prior art referenced in the prior art documents and are not described in detail in this application. The cutting component 4 includes a cutting blade, a sliding support, and an electric lifting rod, etc. The through groove 7 at one end of the long groove 5 is made of 45# steel (rough surface). The internal adjusting block 9 is made of steel and forms a clearance fit with the through groove 7. The clamping block 16 at one end of the adjusting block is made of steel and is connected to the adjusting block 9 through a fine thread. When there is dust inside the clamping block 16, it can be disassembled and cleaned through the threaded connection. The limiting block 11 in the groove 10 is made of bearing steel and cooperates with the return spring 12. The limiting groove 8 on the inner wall of the through groove 7 is interference-fitted with the limiting block. The lifting block 13 is made of stainless steel and slides with the adjusting block 9. During adjustment, the lifting block 13 is raised to disengage the limiting block 11 from the limiting groove 8. After moving the adjusting block 9 to the target position, the reset lock is released.

[0025] Reference Figures 1 to 5 The through groove 7 has a sliding groove 14 inside, and a slider 15 is fixedly installed at one end of the adjusting block 9, and the slider 15 is adapted to the sliding groove 14.

[0026] The above scheme is adopted: the slide groove 14 opened in the through groove 7 is made of carburized steel, the slider 15 at one end of the adjusting block 9 is made of 45# steel, which forms a clearance fit with the slide groove, and the two sides of the slider are rounded.

[0027] Reference Figures 1 to 5 One end of the clamping block 16 is rotatably connected to a half gear 17, and a clamping rod 18 is fixedly installed at one end of the half gear 17. A rubber block is fixedly installed at the bottom end of the clamping rod 18. An adjusting rack 19 is slidably connected to the middle of the clamping block 16, and the adjusting rack 19 is meshed with the half gear 17. A fixing block 20 is fixedly installed at one end of the clamping block 16. The top end of the adjusting rack 19 is symmetrically provided with insertion holes 21, and an insertion rod 22 is inserted into the top end of the adjusting rack 19. The insertion rod 22 is adapted to the insertion hole 21.

[0028] The above scheme is adopted as follows: the half gear 17 at one end of the clamping block 16 is made of alloy steel and is hinged to the clamping block 16 through a carburized steel shaft; the clamping rod 18 is made of steel and connected to a nitrile rubber block at the bottom end; the adjusting rack 19 is made of 45# steel and meshes with the half gear; the fixing block 20 is made of stainless steel; and the insert rod 22 is made of bearing steel and forms a transition fit with the insertion hole 21 at the top of the adjusting rack. When the insert rod 22 is inserted into different insertion holes 21, the half gear 17 drives the clamping rod 18 to achieve adjustment. The end face of the insert rod 22 and the insertion hole 21 is rough, and the top surface of the fixing block 20 also has friction. When the insert rod 22 passes through the insertion hole 21 and abuts against the surface of the fixing block 20, the friction generated will fix the adjusting rack 19 on the surface of the fixing block 20. During insertion, the limiting friction can be increased, the limiting and fixing stability can be increased, and the workpiece surface error can be compensated by the elastic deformation of the rubber block.

[0029] Reference Figures 1 to 5A support rod 3 is fixedly installed at the bottom of the cutting table 1, and the support rod 3 is symmetrically installed at the bottom of the cutting table 1. A dust collection component 23 is provided at the bottom of the cutting table 1, and the dust collection pipe of the dust collection component 23 is connected to one end of the long groove 5.

[0030] The above solution is adopted: the dust collection component 23 is the prior art mentioned in the referenced document and is not described in detail in this application, including the suction pump, the through pipe and the collection tank, etc.

[0031] The working principle of this utility model is as follows: When the adjusting block 9 needs to be adjusted, the lifting block 13 is raised. The lifting block 13 is fixedly installed with the limiting block 11 through the groove 10. Therefore, raising the lifting block 13 will cause the limiting block 11 to slide upward in the groove 10, compressing the return spring 12, so that the limiting block 11 disengages from the limiting groove 8 inside the through groove 7, releasing the limiting lock on the adjusting block 9. At this time, since the slider 15 at one end of the adjusting block 9 is adapted to the sliding groove 14 inside the through groove 7, the adjusting block 9 can be manually pushed to slide freely in the through groove 7. After the adjusting block 9 is moved to the appropriate position, the lifting block 13 is released. Under the elastic force of the return spring 12, the limiting block 11 returns downward and re-locks into the corresponding limiting groove 8, limiting and fixing the adjusting block 9. By sliding the adjusting block 9, plywood 6 of different sizes can be pressed and fixed, increasing the... The machine offers flexibility in use. When the pressing rod 18 is needed to press and fix the plywood 6, first adjust the adjusting block 9 to the appropriate position and fix it. Then, push the adjusting rack 19 to slide in the middle of the pressing block 16. Since the adjusting rack 19 is meshed with the half gear 17, the sliding of the adjusting rack 19 will drive the half gear 17 to rotate. The half gear 17 will drive the pressing rod 18 to rotate and press down, so that the rubber block at the bottom of the pressing rod 18 is in close contact with the plywood 6, thus pressing the plywood 6. After pressing to the appropriate degree, insert the insertion rod 22 into the insertion hole 21 at the top of the adjusting rack 19 to limit and fix the adjusting rack 19, preventing the pressing rod 18 from loosening and rebounding, and ensuring that the plywood 6 remains stable during the cutting process. This achieves flexible adjustment of the position of the adjusting block 9 and reliable pressing and fixing of the plywood 6, ensuring the accuracy and stability of the automatic plywood trimming machine.
