Description

Technical Field

[0001] The present invention relates to the technical field of wood processing, and particularly to a grinding device for processing wood-based panels. Background Art

[0002] Wood-based panels have the advantages of light weight, high strength ratio, good elasticity, impact resistance, rich and beautiful texture and color, and easy processing. At the same time, they have the property of resource regeneration. Wood-based panels have occupied an important position in the national economy since ancient times and are widely used in furniture and toys. Before spraying wood-based panels, it is necessary to treat their surfaces to obtain a relatively smooth and flat surface in order to improve product quality.

[0003] In the prior art, for example, a grinding device for processing wood-based panels disclosed in the application number CN202021960865.X includes: an operating table, a conveyor belt is arranged inside the operating table and is rotatably connected to the operating table, transmission boxes are arranged on both outer sides of the operating table, a chute is arranged inside the transmission box, a third motor is arranged at the left end of the transmission box, and a third screw rod is arranged at the power output end of the third motor. The third screw rod is located inside the chute and a third sliding block is arranged on its surface. In the present utility model, the first screw rod drives the first sliding block to move up and down, thereby realizing the up and down adjustment of the grinding device, increasing the flexibility of the grinding head. At the same time, a fixing frame is arranged on the side surface of the first sliding block and a second screw rod is installed inside the fixing frame.

[0045] A transmission frame 1, in which a plurality of transmission rollers 2 are drivingly connected in the middle, and a wooden board 3 is drivingly arranged on the surface of the transmission roller 2;

[0046] A grinding assembly arranged at the upper and lower ends of the wooden board 3, which is used to grind the wooden board 3 on the front and back sides and the surface.

[0048] A drive assembly for driving the grinding assembly to work, which is used to drive the two transmission belts 401 to synchronously drive and drive the grinding belt 402 to grind the surface and edge of the wooden board 3.

The diameters of the driving roller 403 and the reversing roller 405 corresponding to the position of the grinding belt 402 are smaller than the diameters of the driving roller 403 and the reversing roller 405 corresponding to the position of the transmission belt 401, so that the driving roller 403 cooperates with the reversing roller 405 to play a limiting role in the transmission of the transmission belt 401.

[0051] The support assembly includes a support frame body 501. Both ends of the central axis of the reversing roller 405 are rotatably connected to the middle part of the support frame body 501 through bearings. Hinge arms 502 are respectively hinged to both ends of the support frame body 501. One end of the hinge arm 502 far away from the support frame body 501 is hinged to a movable column 503. The two transmission belts 401 are centrosymmetrically arranged with the midpoint of the connection line of the two movable columns 503 as the center of symmetry, and the two support frame bodies 501 are respectively located at the front and rear ends of the movable column 503. Threaded tubes 504 are respectively fixedly installed at the same ends of the two movable columns 503. Threaded rods 505 are threadedly connected to the inner walls of the two threaded tubes 504. The thread directions at both ends of the threaded rod 505 are opposite. Fixed plates 507 are respectively provided at both ends of the threaded rod 505. One end of the threaded rod 505 is rotatably connected to the middle part of one of the fixed plates 507 through a bearing, and a first forward and reverse motor 506 is fixedly installed at the other end of the threaded rod 505. The first forward and reverse motor 506 is fixedly installed at one end of the other fixed plate 507.

[0052] The driving assembly includes a driving shaft 601. The driving shaft 601 is rotatably connected to the middle part of the movable column 503 through a bearing. Connection frames 602 are respectively rotatably connected to both ends of the driving shaft 601 through bearings. The two connection frames 602 are centrosymmetrically arranged with the midpoint of the driving shaft 601 as the center of symmetry. A receiving groove is formed in the middle part of the movable column 503 corresponding to the position of the driving shaft 601. A worm wheel 603 is rotatably connected to the inner wall of the receiving groove, and the worm wheel 603 is fixedly installed on the surface of the driving shaft 601. A worm rod 604 is engaged with the surface of the worm wheel 603, and the worm rod 604 is rotatably connected to the inner wall of the receiving groove through a bearing.

[0053] The connecting frame 602 is rotatably connected to the middle of the driving roller 403, and the connecting frame 602 movably penetrates and extends to both ends of the driving roller 403. Driven gears 607 are fixedly installed at both ends of the driving roller 403 respectively. A driving gear 606 meshes with the surface of the driven gear 607 at one end away from the movable column 503, and the driving gear 606 is fixedly installed on the surface of the driving shaft 601. The diameter of the driven gear 607 is larger than that of the driving roller 403, so that the driven gear 607 plays a limiting role on the transmission belt 401. One end of the connecting frame 602 away from the driving shaft 601 is fixedly installed with a connecting plate 605. The connecting plate 605 is rotatably connected to the surface of the driving shaft 601 through a bearing, and the connecting plate 605 is located at one end of the movable column 503. A toothed ring 608 is fixedly installed at one end of the connecting plate 605 corresponding to the position of the movable column 503. Two limiting strips 609 are fixedly installed on the surface of the toothed ring 608, and the back surfaces of the two limiting strips 609 are tangent to the surface of the toothed ring 608. The two limiting strips 609 are vertically arranged. Since two vertically arranged limiting strips 609 are fixedly installed on the surface of the toothed ring 608, when the toothed ring 608 rotates 90°, it will be blocked by the limiting strips 609. At the same time, the meshing surface of the toothed ring 608 will be separated from the top of the guide plate 610, so that the reciprocating rotation angle of the toothed ring 608 can only rotate 90°. That is, when the two movable columns 503 move away from each other, the connecting plate 605 rotates 90° around the driving shaft 601. A guide plate 610 meshes with the surface of the toothed ring 608. The guide plate 610 is fixedly installed at one end of the opposite surfaces of the two fixing plates 507. The guide plate 610 is a hollow structure in the middle, and the movable column 503 is movably connected to the inner wall of the guide plate 610. Grooves are opened at both ends of the movable column 503 corresponding to the position of the guide plate 610, and the inner walls of the grooves are slidably connected to the surface of the guide plate 610, so that the guide plate 610 plays a supporting and guiding role on the movable column 503.

[0054] A rhombic column 611 is rotatably connected to the middle of the guide plate 610 through a bearing. The rhombic column 611 is a regular polygon structure. A plug hole is opened in the middle of the worm rod 604, and the size of the plug hole is adapted to the shape and size of the rhombic column 611. One end of the rhombic column 611 is fixedly installed with a second forward and reverse motor 612, and the second forward and reverse motor 612 is fixedly embedded in the middle of the guide plate 610.

[0055] The support frame body 501 is respectively provided with an adjusting component for adjusting the transmission belt 401 and a guiding component for guiding the movement of the support frame body 501. The adjusting component includes an activity groove 701. The activity groove 701 is opened at both ends of the support frame body 501 corresponding to the position of the adjusting roller 404. A slider 702 is slidably connected to the inner wall of the activity groove 701. Both ends of the central axis of the adjusting roller 404 are respectively rotatably connected to the middle of the slider 702 through bearings. A damping spring 703 is fixedly installed at the top of the slider 702, and the damping spring 703 is fixedly installed at the top of the inner wall of the activity groove 701. When the transmission belt 401 presses the adjusting roller 404 or the damping spring 703 drives the adjusting roller 404 to press the transmission belt 401 through the slider 702, the adjusting roller 404 will drive the slider 702 to move up and down on the inner wall of the activity groove 701 and compress or stretch the damping spring 703, so as to achieve the purpose of adjusting the tension of the transmission belt 401. The guiding component includes two guiding blocks 801, and the two guiding blocks 801 are respectively fixedly installed at the front and rear ends of the top of the support frame body 501. A guiding frame 802 is provided on the surface of the guiding block 801. The guiding frame 802 is in a U-shaped structure, and a guiding groove is opened on the inner wall of the guiding frame 802 corresponding to the position of the guiding block 801. The inner wall of the guiding groove is movably connected to the surface of the guiding block 801. A fixed arm 803 is fixedly installed on the surface of the guiding frame 802, and the fixed arm 803 is fixedly installed at one end of the fixed plate 507. By setting the guiding block 801, the guiding frame 802 and the fixed arm 803, when the support frame body 501 moves up and down, it will drive the guiding block 801 to move up and down in the guiding groove of the guiding frame 802 to play a guiding and limiting role for the support frame body 501. Since the fixed arm 803 and the fixed plate 507 are fixedly installed, the cooperation of the guiding block 801 and the guiding frame 802 can make the support frame body 501 move up and down smoothly.

[0056] Two fixing plates 507 are fixedly installed at both ends of the inner wall of the transmission rack 1.

[0057] Working principle: During use, the present invention conveys the wooden board 3 to the grinding assembly through the drive of multiple conveying rollers 2. When the grinding assembly, the support assembly, and the drive assembly are in the initial state, all the connecting plates 605 are perpendicular to the movable column 503. This causes the connecting plate 605 to rotate around the drive shaft 601 and drive the drive roller 403 to rotate around the drive shaft 601 through the connecting frame 602. In the initial position, the midpoints of all the worm rods 604 and the midpoint of the movable column 503 are in a horizontally coplanar state. At this time, the overlapping area of the inner parts of the two transmission belts 401 is relatively large. At this time, the conveying roller 2 can easily pass the wooden board 3 through the two grinding belts 402. When the wooden board 3 is located between the two grinding belts 402, at this time, the first forward and reverse motor 506 is driven to rotate, and the first forward and reverse motor 506 drives the threaded rod 505 to rotate, and the threaded rod 505 drives the two threaded tubes 504 to move away from each other, so that the threaded tubes 504 drive the two movable columns 503 to move away from each other along the direction of the guide plate 610. At the same time, through the hinge connection between the movable column 503 and the hinge arm 502, the hinge arm 502 will drive the support frame 501 to move downward;

[0058] By setting the guide block 801, the guide frame 802, and the fixed arm 803, when the support frame 501 moves up and down, it will drive the guide block 801 to move up and down in the guide groove of the guide frame 802 to play a guiding and limiting role for the support frame 501. Since the fixed arm 803 is fixedly installed with the fixed plate 507, the cooperation of the guide block 801 and the guide frame 802 can enable the support frame 501 to move up and down smoothly;

[0059] Because the support frame 501 can move up and down through the hinge connection between the hinge arm 502 and the movable column 503, it can meet the adjustment of the tension change of the transmission belt 401 caused by the mutual separation of the two drive rollers 403. At the same time, the cooperation of the adjustment assembly can make the transmission belt 401 always closely fit on the surfaces of the drive roller 403, the adjustment roller 404, and the reversing roller 405 and maintain the transmission relationship. Among them, when the tension of the transmission belt 401 changes, by the transmission belt 401 squeezing the adjustment roller 404 or the damping spring 703 driving the adjustment roller 404 to squeeze the transmission belt 401 through the slider 702, it will cause the adjustment roller 404 to drive the slider 702 to move up and down on the inner wall of the movable groove 701 and squeeze or stretch the damping spring 703, so as to achieve the purpose of adjusting the tension of the transmission belt 401. And when replacing, only the transmission belt 401 and the grinding belt 402 need to be replaced. Compared with the prior art, the replacement cost is lower, the quantity is less, and the replacement speed is faster;

[0060] Moreover, when the two movable columns 503 move away from each other, the movable columns 503 drive the connecting plate 605 to move through the drive shaft 601, and the connecting plate 605 drives the top of the gear ring 608 to engage with the guide plate 610. As a result, due to the meshing relationship between the gear ring 608 and the guide plate 610, the connecting plate 605 can rotate around the drive shaft 601. Since two vertically arranged limiting strips 609 are fixedly installed on the surface of the gear ring 608, when the gear ring 608 rotates 90°, it will be blocked by the limiting strips 609, and at the same time, the meshing surface of the gear ring 608 will separate from the top of the guide plate 610, so that the reciprocating rotation angle of the gear ring 608 can only rotate 90°. That is, when the two movable columns 503 move away from each other, the connecting plate 605 rotates 90° around the drive shaft 601, making the connecting plate 605 parallel to the movable columns 503. At this time, the two pairs of drive rollers 403 driven on the two transmission belts 401 are respectively located at the top and bottom of the wood board 3, which will cause the transmission belt 401 to drive the polishing belt 402 to fit on the surface and both ends of the wood board 3, and under the elastic adjustment of the adjustment component, the polishing belt 402 is closely attached to the wood board 3. At this time, the second forward and reverse motor 612 drives the diamond column 611 to rotate, and the diamond column 611 drives the worm rod 604 to rotate, so that the worm rod 604 drives the drive shaft 601 to rotate through the worm wheel 603. And when the drive shaft 601 rotates, the drive shaft 601 drives the drive gear 606 to rotate, and the drive gear 606 drives the driven gear 607 to rotate, so that the driven gear 607 drives the drive roller 403 to rotate and drives the transmission belt 401 to drive. Since the second forward and reverse motor 612 can drive the diamond column 611 to reciprocate, the drive roller 403 will reciprocally drive the transmission belt 401 to drive, so that the transmission belt 401 reciprocally moves on the surface of the wood board 3, thereby achieving the purpose of polishing the surface and both ends of the wood board 3; Embodiment

[0061] Different from the first embodiment, the two fixing plates 507 are slidably connected to both ends of the inner wall of the transmission frame 1 through a pneumatic slide table. The fixing plates 507 are installed on the inner wall of the transmission frame 1 through a pneumatic slide table (not shown in the figure). That is, while the polishing belt 402 reciprocally moves on the surface of the wood board 3, the fixing plates 507 are driven to reciprocally move back and forth, and the fixing plates 507 cooperate with the guide plate 610 and the threaded rod 505 to drive the movable columns 503 to reciprocally move back and forth, which will cause the movable columns 503 to drive the polishing belt 402 to reciprocally move back and forth through the drive rollers 403, and make the polishing belt 402 add a reciprocating back and forth movement process while reciprocally moving left and right, so that the wood board 3 is polished more thoroughly.
