Description

Technical Field

[0001] The utility model relates to the technical field of marble plate polishing, and particularly relates to a polishing machine for producing artificial marble plates. Background Technique

[0002] Artificial marble is processed by imitating the surface texture of marble, has similar mechanism characteristics to marble, and the pattern can be determined by the designer himself, with good reproducibility. Moreover, artificial marble is pollution-resistant and has good workability, and can be made into arc-shaped, curved and other shapes, which is convenient for construction.

[0003] The existing Chinese patent: a polishing machine for producing artificial marble plates, patent number: CN212351575U, includes a workbench, and a protective cover is fixedly installed in the middle of the top surface of the workbench. The utility model uses a conveyor belt as an automatic feeding structure to reduce the labor intensity of workers. By rotating the lead screw by a second servo motor, the nut drives the polishing structure formed by the mounting frame, the first servo motor and the polishing disc to reciprocate. At the same time, the first servo motor drives the polishing disc to rotate to convert it into a polishing state. By using the above two in combination, the device can have the function of automatically polishing marble. And the adjusting structure formed by the anti-sway frame and the fixed roller sleeve can drive the gap adjustment between the movable roller and the conveyor belt, so that the movable roller can be closely attached to the surface of the marble plate subsequently to limit the amplitude of the up and down deflection when the marble plate is polished, and ensure the flatness after polishing.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: in the above polishing machine, the marble plate is moved to the polishing area through the conveyor belt, and the marble plate is only driven by the friction force between the conveyor belt. When polishing, the force generated by the polishing disc is likely to cause the marble plate to shift, resulting in uneven polishing. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a polishing machine for producing artificial marble plates, which solves the technical problem that in the above polishing machine, the marble plate is moved to the polishing area through the conveyor belt, and the marble plate is only driven by the friction force between the conveyor belt. When polishing, the force generated by the polishing disc is likely to cause the marble plate to shift, resulting in uneven polishing.

[0007] (2) Technical Solutions

[0008] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0009] A polishing machine for producing artificial marble plates, comprising a support frame. Inside the support frame, a workbench is slidably installed. At the top of the workbench, two clamping plates are symmetrically and slidably installed. At the bottom ends of the two clamping plates, first racks are fixedly installed. Inside the workbench, a connecting rod is rotatably installed. At the top end of the connecting rod, a first straight-tooth gear is fixedly installed. At the bottom end of the connecting rod, a first bevel gear is fixedly installed. At the bottom end of the support frame, a transmission rod is rotatably installed. On the outer side wall of the transmission rod, a second bevel gear is fixedly installed. The two first racks are respectively meshed with the first straight-tooth gear, and the first bevel gear is meshed with the second bevel gear. Inside the support frame, two rollers are symmetrically and rotatably installed. On the outer side wall of the rollers, three polishing belts are installed. At the side ends of the two rollers, first transmission wheels are fixedly installed. Between the two first transmission wheels, they are connected by a transmission belt. At the top end of the support frame, a second motor is fixedly installed. At the side end of the second motor, a second transmission wheel is fixedly installed. The second transmission wheel is connected to the first transmission wheel by a transmission belt. At the bottom end of the workbench, a bidirectional threaded rod is rotatably installed. At the bottom end of the workbench, two clamping blocks are symmetrically and slidably installed. The two clamping blocks are threadedly connected to the bidirectional threaded rod. At the bottom end of the workbench, a first motor is fixedly installed. At the side end of the first motor, a second straight-tooth gear is fixedly installed.

[0010] Preferably: A second rack is fixedly installed at the side end of the support frame; the second rack is meshed with the second straight-tooth gear.

[0011] Preferably: Rubber pads are fixedly installed at the side ends of the two clamping blocks.

[0012] (III) Beneficial effects

[0013] First, place the marble plate above the workbench and rotate the transmission rod clockwise. The transmission rod will drive the second bevel gear to rotate clockwise. Since the second bevel gear is meshed with the first bevel gear, the second bevel gear will cause the first bevel gear to rotate counterclockwise. The first bevel gear will drive the first straight-tooth gear to rotate counterclockwise through the connecting rod. Since the first straight-tooth gear is meshed with the two first racks, the first straight-tooth gear will cause the two first racks to drag the clamping plates to slide inward simultaneously, enabling the clamping plates to clamp the marble plate. Then rotate the bidirectional threaded rod counterclockwise. Since the bidirectional threaded rod is threadedly connected to the two clamping blocks, when the bidirectional threaded rod rotates counterclockwise, the two clamping blocks will slide inward simultaneously, clamping the connecting rod tightly. The rubber pads on the clamping blocks increase the friction between the clamping blocks and the connecting rod, preventing the connecting rod from rotating during use. By rotating the transmission rod to make the two clamping plates slide, the fixation of the marble plate is completed, achieving the effect of preventing the marble plate from shifting under force during polishing, which may cause uneven polishing.

[0014] Second, after fixing the marble slab, the first motor is started to drive the second spur gear to rotate. Since the second spur gear meshes with the second rack, the first motor will drag the workbench to slide, moving the marble slab to the polishing area. Three polishing belts are installed on the roller, and the polishing mesh numbers of these three polishing belts gradually increase from right to left. The second motor is started to drive the second driving wheel to rotate, and the second driving wheel will drive two first driving wheels to rotate through the transmission belt, thereby causing the three polishing belts to rotate. When the workbench gradually slides from right to left, the marble slab will be gradually polished from coarse to fine by the three polishing belts. Through the three polishing belts installed on the roller, the step-by-step polishing of the marble slab from coarse to fine is completed, achieving the effect of improving the polishing quality.

[0022] In an embodiment of the present application, by providing a polishing machine for producing artificial marble plates, the above-mentioned technical problem of the polishing machine is effectively solved. That is, the marble plate is moved to the polishing area through a conveyor belt, and the marble plate is driven only by the frictional force between it and the conveyor belt. During polishing, the force generated by the polishing disc easily causes the marble plate to shift, resulting in uneven polishing. The marble plate is placed above the workbench. Rotate the transmission rod clockwise. The transmission rod will drive the second bevel gear to rotate clockwise. Since the second bevel gear meshes with the first bevel gear, the second bevel gear will cause the first bevel gear to rotate counterclockwise. The first bevel gear will drive the first spur gear to rotate counterclockwise through the connecting rod. Since the first spur gear meshes with two first racks, the first spur gear will cause the two first racks to drag the clamping plates to slide inward simultaneously, enabling the clamping plates to clamp the marble plate. Then rotate the bidirectional threaded rod counterclockwise. Since the bidirectional threaded rod is threadedly connected to two clamping blocks, when the bidirectional threaded rod rotates counterclockwise, the two clamping blocks will slide inward simultaneously, clamping the connecting rod. The rubber pads on the clamping blocks increase the frictional force between the clamping blocks and the connecting rod, preventing the connecting rod from rotating during use. By rotating the transmission rod to slide the two clamping plates, the fixation of the marble plate is completed, achieving the effect of preventing the marble plate from shifting due to force during polishing and resulting in uneven polishing. After fixing the marble plate, the first motor starts to drive the second spur gear to rotate. Since the second spur gear meshes with the second rack, the first motor will drag the workbench to slide, moving the marble plate to the polishing area. Three polishing belts are installed on the drum, and the polishing mesh numbers of these three polishing belts gradually increase from right to left. The second motor starts to drive the second transmission wheel to rotate. The second transmission wheel will drive two first transmission wheels to rotate through the conveyor belt, thereby causing the three polishing belts to rotate. When the workbench slides gradually from right to left, the marble plate will be polished step by step from coarse to fine by the three polishing belts. Through the three polishing belts installed on the drum, the marble plate is gradually polished from coarse to fine, achieving the effect of improving the polishing quality.

[0023] Embodiment

[0024] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the technical solution in the embodiment of the present application effectively solves the above-mentioned technical problem of the polishing machine. That is, the marble plate is moved to the polishing area through a conveyor belt, and the marble plate is driven only by the frictional force between it and the conveyor belt. During polishing, the force generated by the polishing disc easily causes the marble plate to shift, resulting in uneven polishing. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a polishing machine for producing artificial marble plates, which comprises a support frame 1. A workbench 2 is slidably installed inside the support frame 1. Two clamping plates 3 are symmetrically and slidably installed at the top end of the workbench 2. First racks 4 are fixedly installed at the bottom ends of the two clamping plates 3. A connecting rod 15 is rotatably installed inside the workbench 2. A first spur gear 5 is fixedly installed at the top end of the connecting rod 15. A first bevel gear 6 is fixedly installed at the bottom end of the connecting rod 15. A transmission rod 7 is rotatably installed at the bottom end of the support frame 1. A second bevel gear 8 is fixedly installed on the outer side wall of the transmission rod 7.

[0026] The two first racks 4 are respectively meshed with the first spur gear 5. The first bevel gear 6 is meshed with the second bevel gear 8. Two rollers 16 are symmetrically and rotatably installed inside the support frame 1. Three polishing belts 17 are installed on the outer side wall of the rollers 16. First transmission wheels 18 are fixedly installed at the side ends of the two rollers 16. The two first transmission wheels 18 are connected by a transmission belt. A second motor 21 is fixedly installed at the top end of the support frame 1. A second transmission wheel 19 is fixedly installed at the side end of the second motor 21.

[0027] The second transmission wheel 19 is connected with the first transmission wheel 18 by a transmission belt. A bidirectional threaded rod 9 is rotatably installed at the bottom end of the workbench 2. Two clamping blocks 11 are symmetrically and slidably installed at the bottom end of the workbench 2. The two clamping blocks 11 are threadedly connected with the bidirectional threaded rod 9. A first motor 13 is fixedly installed at the bottom end of the workbench 2. A second spur gear 14 is fixedly installed at the side end of the first motor 13. A second rack 22 is fixedly installed at the side end of the support frame 1. The second rack 22 is meshed with the second spur gear 14. Rubber pads 12 are fixedly installed at the side ends of the two clamping blocks 11.

[0028] Working principle:

[0029] First step, place the marble slab above the workbench 2, and rotate the transmission rod 7 clockwise. The transmission rod 7 will drive the second bevel gear 8 to rotate clockwise. Since the second bevel gear 8 meshes with the first bevel gear 6, the second bevel gear 8 will cause the first bevel gear 6 to rotate counterclockwise. The first bevel gear 6 will drive the first spur gear 5 to rotate counterclockwise through the connecting rod 15. Since the first spur gear 5 meshes with the two first racks 4, the first spur gear 5 will cause the two first racks 4 to drag the clamping plates 3 to slide inward simultaneously, enabling the clamping plates 3 to clamp the marble slab. Then, rotate the bidirectional threaded rod 9 counterclockwise. Since the bidirectional threaded rod 9 is threadedly connected to the two clamping blocks 11, when the bidirectional threaded rod 9 rotates counterclockwise, the two clamping blocks 11 will slide inward simultaneously, clamping the connecting rod 15. The rubber pads 12 on the clamping blocks 11 increase the friction between the clamping blocks 11 and the connecting rod 15, preventing the connecting rod 15 from rotating during use. By rotating the transmission rod 7 to slide the two clamping plates 3, the fixation of the marble slab is completed, achieving the effect of preventing the marble slab from shifting under force during polishing, which may cause uneven polishing.

[0030] Second step, after fixing the marble slab, start the first motor 13 to drive the second spur gear 14 to rotate. Since the second spur gear 14 meshes with the second rack 22, the first motor 13 will drag the workbench 2 to slide, moving the marble slab to the polishing area. Three polishing belts 17 are installed on the roller 16, and the polishing mesh numbers of these three polishing belts 17 gradually increase from right to left. Start the second motor 21 to drive the second transmission wheel 19 to rotate. The second transmission wheel 19 will drive the two first transmission wheels 18 to rotate through the transmission belt, thereby causing the three polishing belts 17 to rotate. When the workbench 2 slides gradually from right to left, the marble slab will be polished step by step from coarse to fine by the three polishing belts 17. Through the three polishing belts 17 installed on the roller 16, the gradual polishing of the marble slab from coarse to fine is completed, achieving the effect of improving the polishing quality.

[0031] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
