[0019] The present invention has the following beneficial effects:

[0020] (1) For a wood grinding processing device based on different diameters of wood in the present invention, the log to be ground is placed on several arc-shaped support plates in the grinding box, and then the threaded hollow block is screwed on. The threaded hollow block moves into the grinding box. The hollow block will contact the log in the grinding box, and the log will be pushed to contact the tooth disc. The tooth disc will drive the telescopic rod to compress. At this time, the clamping spring and the telescopic spring will both undergo compressive deformation. During the compression of the telescopic rod, it will drive the circular plate to move away from the threaded hollow block. The circular plate drives several L-shaped transmission plates to move synchronously. The L-shaped transmission plate drives the first inclined plate to move. The first inclined plate drives the slide rod to move towards the log. The slide rod drives the C-shaped mounting plate to move. The C-shaped mounting plate will drive the tooth roller to contact the log. When several tooth rollers simultaneously contact the log, the clamping of the log is completed. At this time, the threaded hollow block can no longer rotate. By rotating the depth of the threaded hollow block entering the grinding box, logs of different diameters can be clamped, effectively improving the application range and flexibility of the device;

[0021] (2) The present invention is a device for grinding wood of different diameters. After fixing the log, the motor is started, the motor drives the corresponding rotating rod to rotate, the rotating rod drives the gear roller to rotate, the gear roller drives the log to rotate, the log drives the gear plate to rotate, the gear plate drives the transmission gear roller to rotate, the transmission gear roller drives the threaded rod to rotate, the threaded rod drives the internal thread transmission plate to move in the direction away from the grinding box, the internal thread transmission plate drives the second inclined plate to move, the second inclined plate drives the rectangular mounting plate to descend, the rectangular mounting plate drives the threaded adjustment rod to descend, the threaded adjustment rod drives the limit sliding plate to descend, the limit sliding plate drives the H-shaped arc plate to descend, the H-shaped arc plate will gradually drive the two grinding blocks to move in the direction close to the log, when the grinding block contacts the log, the grinding block will grind the surface of the log under the rotation of the log to make it smoother, when grinding logs of different diameters, by rotating the threaded adjustment rod, the threaded adjustment rod will drive the limit sliding plate to rise and fall, so that the depth of the grinding block can be adjusted, thereby improving the flexibility of grinding;

[0022] (3) The present invention is a device for grinding wood of different diameters. When the internal thread transmission plate moves away from the grinding box, the transmission spring is compressed and deformed. When the internal thread transmission plate leaves the threaded portion on the threaded rod, the corresponding internal thread transmission plate will be affected by the compression elastic force of the transmission spring, so that the internal thread transmission plate remains in a semi-disconnected state, thereby ensuring the stability of the grinding of the grinding block and will not affect the normal rotation of the threaded rod. The continuous rotation of the threaded rod will drive a number of fan blades to rotate, and the fan blades will generate a suction force. The suction force is sucked toward the upper part of the grinding box through the L-shaped circular tube, the chip conveying tube, the filter box, the L-shaped tube and the collecting cover, and the flying chips and dust generated during the grinding of the logs are absorbed into the filter box. The suction force will also suck from the L-shaped tube and the collecting hood to the bottom part of the grinding box, and collect the larger wood chips from the grinding of the logs into the filter box, so as to avoid excessive accumulation of wood chips in the grinding box, which will cause the grinding box to be unable to perform normal grinding work. The wood chips after passing through the filter box will remain in the filter box for centralized treatment.

[0023] (4) The present invention is a device for grinding wood of different diameters. During the process of the toothed roller driving the log to rotate and grind, wood chips will remain in several toothed rollers. Long-term accumulation will fill the tooth gaps on the toothed rollers. When the toothed rollers rotate, they will contact the trapezoidal plate. When the corresponding teeth contact the trapezoidal plate, the trapezoidal plate will slide into the special-shaped hollow plate. At this time, the chip removal spring will be compressed and deformed. When the corresponding teeth leave the trapezoidal plate, the trapezoidal plate will enter the next tooth gap under the elastic force of the chip removal spring. In this way, the reciprocating trapezoidal plate will continuously scrape the wood chips in the tooth gap during the rotation of the toothed roller, thereby avoiding the accumulation of wood chips in the tooth gap, which will cause the toothed roller to be unable to drive the log to rotate normally, affecting the grinding effect.

[0024] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a grinding processing device for woods with different diameters, including a grinding box 1. An extension rod 2 is fixedly installed on the inner wall of the back surface of the grinding box 1. The output end of the extension rod 2 is fixedly installed with a circular plate 3. A telescopic spring 4 is sleeved on the extension rod 2. The end of the telescopic spring 4 is fixedly connected with the grinding box 1, and the front end of the telescopic spring 4 is fixedly connected with the circular plate 3. A plurality of arc-shaped support plates 401 are fixedly installed in the grinding box 1. A toothed disc 507 is rotatably installed on the front surface of the circular plate 3. The device further includes:

[0038] A plurality of clamping mechanisms 5. The clamping mechanism 5 includes a sliding rod 503, a transmission component for driving the sliding rod 503 to move, and a clamping component for driving the sliding rod 503 to clamp.

[0039] The transmission component includes an L-shaped transmission plate 501 fixedly installed on the outer wall of the circular plate 3. The front end of the L-shaped transmission plate 501 is hingedly installed with a first inclined plate 502. The top end of the first inclined plate 502 is hinged to the sliding rod 503. The top end of the sliding rod 503 slides and extends into the grinding box 1.

[0040] The clamping assembly includes a U-shaped mounting plate 504 fixedly installed at the top of the sliding rod 503. A rotating rod 505 is rotatably installed inside the U-shaped mounting plate 504, and a toothed roller 506 is fixedly sleeved on the rotating rod 505.

[0041] As Figure 2 shown, a threaded hollow round block 508 is threadedly installed on the front of the grinding box 1. The end of the threaded hollow round block 508 extends into the grinding box 1. A rotating disc 509 is rotatably installed on the inner wall of the back of the threaded hollow round block 508. A clamping spring 510 is fixedly installed on the back of the rotating disc 509. The end of the clamping spring 510 is fixedly installed with a hollow round block 511, and the back of the hollow round block 511 slides and extends outside the threaded hollow round block 508.

[0042] Then screw on the threaded hollow round block 508. The threaded hollow round block 508 moves into the grinding box 1. The hollow round block 511 will contact the round log inside the grinding box 1. The round log will be pushed to contact the toothed disc 507. The toothed disc 507 will drive the telescopic rod 2 to compress. At this time, both the clamping spring 510 and the telescopic spring 4 will undergo compressive deformation. During the compression of the telescopic rod 2, it will drive the round plate 3 to move away from the threaded hollow round block 508.

[0043] As Figure 4 shown, a motor 512 is fixedly installed on the front of the corresponding U-shaped mounting plate 504. The front end of the corresponding rotating rod 505 extends outside the corresponding U-shaped mounting plate 504 and is fixedly connected to the output shaft of the motor 512.

[0044] After fixing the round log, start the motor 512. The motor 512 drives the corresponding rotating rod 505 to rotate. The rotating rod 505 drives the toothed roller 506 to rotate, and the toothed roller 506 drives the round log to rotate.

[0045] As Figure 4 shown, a chip removal mechanism 6 is provided on several U-shaped mounting plates 504. The chip removal mechanism 6 includes several cleaning components, meshing components and cleaning components. The cleaning components include special-shaped hollow plates 601 respectively fixedly installed on the left and right sides of the U-shaped mounting plate 504. Several chip removal springs 602 are fixedly installed on the bottom inner wall of the special-shaped hollow plates 601. Trapezoidal plates 603 are respectively slidably installed in the two special-shaped hollow plates 601. The tops of several chip removal springs 602 are fixedly connected to the bottoms of the two trapezoidal plates 603.

[0046] When the toothed roller 506 drives the log to rotate and grind, wood chips will remain in several toothed rollers 506. Long-term accumulation will fill the tooth gaps on the toothed roller 506. When the toothed roller 506 rotates, it will contact the trapezoidal plate 603. When the corresponding teeth contact the trapezoidal plate 603, the trapezoidal plate 603 will slide into the special-shaped hollow plate 601. At this time, the chip removing spring 602 is compressed and deformed. When the corresponding teeth leave the trapezoidal plate 603, the trapezoidal plate 603 will enter the next tooth gap under the elastic force of the chip removing spring 602. In this way, the reciprocating trapezoidal plate 603 will continuously scrape off the wood chips in the tooth gap during the rotation of the toothed roller 506 to avoid the accumulation of wood chips in the tooth gap, which will cause the toothed roller 506 to be unable to drive the log to rotate normally, affecting the grinding effect.

[0047] like Figure 2 As shown, the meshing assembly includes a threaded rod 604 rotatably mounted in the grinding box 1 , the end of the threaded rod 604 extends outside the grinding box 1 , a transmission gear roller 605 is fixedly sleeved on the threaded rod 604 , and the transmission gear roller 605 meshes with the gear disc 507 .

[0048] The toothed disc 507 drives the transmission gear roller 605 to rotate, the transmission gear roller 605 drives the threaded rod 604 to rotate, and the threaded rod 604 drives the internal thread transmission plate 702 to move in a direction away from the grinding box 1 .

[0049] like Figure 7 and Figure 8 As shown, the cleaning assembly includes a bellows 606 fixedly mounted on the back of the grinding box 1, a threaded rod 604 passes through the bellows 606 and is rotatably connected to the bellows 606, a plurality of fan blades 607 are fixedly mounted on the threaded rod 604, two L-shaped circular tubes 608 are fixedly mounted on the outer wall of the bellows 606, chip conveying pipes 609 are fixedly mounted on the bottom ends of the two L-shaped circular tubes 608, filter boxes 610 are fixedly mounted on the left and right sides of the grinding box 1, and the two chip conveying pipes 609 are communicated with the two filter boxes 610, respectively.

[0050] The continuous rotation of the threaded rod 604 will drive the plurality of fan blades 607 to rotate, and the fan blades 607 will generate a suction force, which will suck air toward the upper part of the grinding box 1 through the L-shaped circular tube 608, the chip conveying tube 609, the filter box 610, the L-shaped tube 611 and the collecting cover 612, and absorb the flying chips and dust generated during the grinding of the logs into the filter box 610.

[0051] like Figure 3 , Figure 6 and Figure 7As shown in the figure, L-shaped pipes 611 are fixedly installed at the tops of two filter boxes 610 respectively. Collection hoods 612 are fixedly installed on the inner top walls of the grinding box 1 respectively. One ends of the two L-shaped pipes 611 close to each other extend into the grinding box 1 and communicate with the two collection hoods 612 respectively. C-shaped pipes 613 are fixedly installed at the bottoms of the two filter boxes 610 respectively. Collection air hoods 614 are fixedly installed on the inner bottom walls of the grinding box 1 respectively. One ends of the two C-shaped pipes 613 close to each other extend into the grinding box 1 and communicate with the two collection air hoods 614 respectively.

[0052] The suction force will also suck air from the C-shaped pipe 613 and the collection air hood 614 to the bottom part inside the grinding box 1, collect the larger wood chips ground from the round log into the filter box 610, and prevent excessive accumulation of wood chips in the grinding box 1 from causing the grinding box 1 to be unable to perform normal chip grinding work. The wood chips passing through the filter box 610 will remain in the filter box 610 for centralized treatment.

[0053] As Figure 8 shown in the figure, a transmission mechanism 7 is arranged on the back of the grinding box 1. The transmission mechanism 7 includes an L-shaped mounting plate 701 fixedly installed on the back of the grinding box 1. The end of the threaded rod 604 is rotatably connected to the L-shaped mounting plate 701. An internally threaded transmission plate 702 is sleeved on the threaded rod 604. A transmission spring 703 is sleeved on the threaded rod 604. The front end of the transmission spring 703 is fixedly connected to the internally threaded transmission plate 702. The end of the transmission spring 703 is fixedly connected to the L-shaped mounting plate 701. A limiting slide rod 704 is fixedly installed on the L-shaped mounting plate 701 and the threaded rod 604. The limiting slide rod 704 penetrates through the internally threaded transmission plate 702 and is slidably connected to the internally threaded transmission plate 702.

[0054] When the internally threaded transmission plate 702 moves away from the grinding box 1, the transmission spring 703 undergoes a compressive deformation. When the internally threaded transmission plate 702 leaves the threaded part of the threaded rod 604, the corresponding internally threaded transmission plate 702 will be affected by the compressive elastic force of the transmission spring 703, keeping the internally threaded transmission plate 702 in a semi-disengaged state from the thread, thereby ensuring the stability of the grinding of the grinding block 710 and not affecting the normal rotation of the threaded rod 604.

[0055] As Figure 3 and Figure 6 shown in the figure, an inclined plate two 705 is hingedly installed at the end of the internally threaded transmission plate 702. The bottom end of the inclined plate two 705 is hingedly installed with a rectangular mounting plate 706. A threaded adjusting rod 707 is threadedly installed through the rectangular mounting plate 706. A limiting sliding plate 708 is rotatably installed at the bottom of the threaded adjusting rod 707.

[0056] The internal thread transmission plate 702 drives the inclined plate 2 705 to move, the inclined plate 2 705 drives the rectangular mounting plate 706 to descend, the rectangular mounting plate 706 drives the threaded adjustment rod 707 to descend, and the threaded adjustment rod 707 drives the limit sliding plate 708 to descend.

[0057] like Figure 1 - Figure 8 As shown, the bottom end of the limiting sliding plate 708 slides and extends into the grinding box 1, an H-shaped arc plate 709 is fixedly installed at the bottom of the limiting sliding plate 708, and two grinding blocks 710 are fixedly installed at the bottom of the H-shaped arc plate 709.

[0058] The limiting sliding plate 708 drives the H-shaped arc plate 709 to descend, and the H-shaped arc plate 709 will gradually drive the two grinding blocks 710 to move towards the direction close to the log. When the grinding blocks 710 come into contact with the log, the grinding blocks 710 will grind the surface of the log under the rotation of the log to make it smoother. When grinding logs of different diameters, the threaded adjustment rod 707 is rotated, and the threaded adjustment rod 707 drives the limiting sliding plate 708 to rise and fall, thereby adjusting the depth of the descent of the grinding blocks 710, thereby improving the flexibility of grinding.

[0059] During use, place the log to be ground on several arc-shaped support plates 401 inside the grinding box 1, then screw on the threaded hollow block 508. The threaded hollow block 508 moves into the grinding box 1, and the hollow block 511 will contact the log inside the grinding box 1. The log will be pushed to contact the tooth disc 507, and the tooth disc 507 will drive the telescopic rod 2 to compress. At this time, the clamping spring 510 and the telescopic spring 4 will both undergo compressive deformation. During the compression of the telescopic rod 2, it will drive the circular plate 3 to move away from the threaded hollow block 508. The circular plate 3 drives several L-shaped transmission plates 501 to move synchronously. The L-shaped transmission plate 501 drives the inclined plate 1 502 to move. The inclined plate 1 502 drives the slide bar 503 to move towards the log. The slide bar 503 drives the C-shaped mounting plate 504 to move. The C-shaped mounting plate 504 will drive the tooth roller 506 to contact the log. When several tooth rollers 506 simultaneously contact the log, the clamping of the log is completed. At this time, the threaded hollow block 508 can no longer rotate. By rotating the depth of the threaded hollow block 508 entering the grinding box 1, logs with different diameters can be clamped, effectively improving the applicable range and flexibility of the device. After fixing the log, start the motor 512. The motor 512 drives the corresponding rotating rod 505 to rotate. The rotating rod 505 drives the tooth roller 506 to rotate. The tooth roller 506 drives the log to rotate. The log drives the tooth disc 507 to rotate. The tooth disc 507 drives the transmission tooth roller 605 to rotate. The transmission tooth roller 605 drives the threaded rod 604 to rotate. The threaded rod 604 drives the internally threaded transmission plate 702 to move away from the grinding box 1. The internally threaded transmission plate 702 drives the inclined plate 2 705 to move. The inclined plate 2 705 drives the rectangular mounting plate 706 to descend. The rectangular mounting plate 706 drives the threaded adjustment rod 707 to descend. The threaded adjustment rod 707 drives the limit sliding plate 708 to descend. The limit sliding plate 708 drives the H-shaped arc plate 709 to descend. The H-shaped arc plate 709 will gradually drive the two grinding blocks 710 to move towards the log. When the grinding blocks 710 contact the log, under the rotation of the log, the grinding blocks 710 will polish the surface of the log to make it smoother. When grinding logs with different diameters, by rotating the threaded adjustment rod 707, the threaded adjustment rod 707 will drive the limit sliding plate 708 to rise and fall, so as to adjust the depth of the grinding blocks 710 descending, thereby improving the flexibility of grinding.

[0060] When the internal thread transmission plate 702 moves away from the grinding box 1, the transmission spring 703 is compressed and deformed. When the internal thread transmission plate 702 leaves the threaded portion on the threaded rod 604, the corresponding internal thread transmission plate 702 is affected by the compression elastic force of the transmission spring 703, so that the internal thread transmission plate 702 remains in a semi-disengaged thread state, thereby ensuring the grinding stability of the grinding block 710 and not affecting the normal rotation of the threaded rod 604. The threaded rod 604 is held The continuous rotation will drive several blades 607 to rotate, and the blades 607 will generate suction force, which will suck air to the upper part of the grinding box 1 through the L-shaped circular tube 608, the chip conveying tube 609, the filter box 610, the L-shaped tube 611 and the collecting cover 612, and absorb the flying chips and dust generated during the grinding of the logs into the filter box 610. The suction force will also suck air from the L-shaped tube 613 and the collecting cover 614 to the bottom part of the grinding box 1, and the enlarged wood chips generated by the grinding of the logs will be sucked into the filter box 610. The wood chips are collected in the filter box 610 to avoid excessive accumulation of wood chips in the grinding box 1, which may cause the grinding box 1 to be unable to perform normal grinding work. The wood chips after passing through the filter box 610 will be left in the filter box 610 for centralized processing. During the process of the toothed roller 506 driving the log to rotate and grind, wood chips will remain in several toothed rollers 506. Long-term accumulation will fill the tooth gaps on the toothed roller 506. When the toothed roller 506 rotates, it will contact the trapezoidal plate 603. When the corresponding teeth contact the trapezoidal plate 603, the tooth gaps on the toothed roller 506 will be filled. 3, the trapezoidal plate 603 will slide into the special-shaped hollow plate 601, and the chip removing spring 602 will be compressed and deformed. When the corresponding tooth leaves the trapezoidal plate 603, the trapezoidal plate 603 will enter the next tooth gap under the elastic force of the chip removing spring 602. In this way, the reciprocating trapezoidal plate 603 will continuously scrape the wood chips in the tooth gap during the rotation of the tooth roller 506, avoiding the accumulation of wood chips in the tooth gap, resulting in the tooth roller 506 being unable to drive the log to rotate normally, affecting the grinding effect.
