[0001] The utility model relates to the technical field of pressing of sanding machines, and in particular to a pressing mechanism of a furniture sanding machine. Background Art

[0002] The furniture manufacturing industry has higher and higher requirements for product quality. The edge of the board after sanding needs to be flat, smooth and burr-free. In order to meet market demand, the clamping mechanism has become an indispensable part of the furniture edge sanding machine to ensure the edge quality of the board after sanding.

[0003] During use of the existing clamping mechanism of the sanding machine, the clamping device cannot adjust the clamping force and position of materials with different thicknesses, because the pressure of the existing clamping mechanism is constant and cannot be adjusted. When a thicker plate is clamped, the plate may be subjected to greater pressure, and indentations may appear on the surface of the plate. When a thinner plate is clamped, the plate may become loose or offset. Therefore, a clamping mechanism for a furniture sanding machine is proposed. Utility Model Content

When a thicker plate is pressed, the plate may be subjected to a greater pressure and an indentation may appear on the surface of the plate; when a thinner plate is pressed, the plate may become loose or offset.

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1 to Figure 4 As shown, this embodiment proposes a furniture sanding machine clamping mechanism, which is characterized by comprising a clamping mechanism body 1, a transmission assembly 5 is arranged inside the clamping mechanism body 1, lifting assemblies 4 are fixed on both sides of the top of the clamping mechanism body 1, a clamping assembly 2 is arranged in the middle of the lifting assembly 4, and a fixing assembly 3 is arranged inside the clamping mechanism body 1;

[0024] The clamping assembly 2 includes a cylindrical block 21, a cylindrical rod 22 is fixed to the bottom of the cylindrical block 21, a support plate 23 is fixed to the bottom of the cylindrical rod 22, a pressure sensor 24 is fixed to the side of the support plate 23, a fixing frame 25 is fixed to the bottom of the support plate 23, and a clamping wheel 26 is arranged at the bottom of the fixing frame 25.

[0025] Preferably, the lifting assembly 4 includes a support column 41, a rack 42 is fixed on the inner side of the support column 41, a support rod 44 is sleeved on the outer side of the support column 41, a display screen 27 is arranged on the outer side of the support rod 44, a tooth groove 46 is opened inside the support rod 44, a first servo motor 45 is fixed on the side of the support rod 44, and the output end of the first servo motor 45 passes through the support rod 44 and is fixedly connected to the gear 43.

[0026] Preferably, the transmission assembly 5 includes a second servo motor 51 , the output end of the second servo motor 51 passes through the clamping mechanism body 1 and is fixedly connected to a rotating rod 52 , a conveyor belt 53 is sleeved on the rotating rod 52 , and two rotating rods 52 are sleeved in the conveyor belt 53 .

[0027] Preferably, the gear 43 is meshingly connected with the rack 42 .

[0028] Preferably, the number of the support columns 41 is four, and a rack 42 is fixed on each of the four support columns 41. A support rod 44 is fixed in each of two support columns 41 at the same level. The number of the first servo motors 45 is two, and the two first servo motors 45 are horizontally fixed on both sides of the support rod 44. The output end of the first servo motor 45 is fixedly connected to a gear 43.

[0029] In this embodiment, the plate is first placed on the conveyor belt 53, and the conveyor belt 53 is driven to work by the output end of the second servo motor 51. The clamping force on the plate is sensed by the pressure sensor 24 and transmitted back to the display screen 27. By sensing the pressure of plates of different thicknesses, the clamping mechanism applies corresponding clamping forces to plates of different thicknesses. The gear 43 is driven to move on the rack 42 by the output end of the first servo motor 45, so that the clamping wheel 26 set at the bottom of the fixed frame 25 fixed at the bottom of the support rod 44 applies a clamping force corresponding to the thickness of the plate to the plate. This solves the problem that the pressure of the existing clamping mechanism is constant and cannot be adjusted. When a thicker plate is clamped, the plate may be subjected to a greater pressure and an indentation will appear on the surface of the plate. When a thinner plate is clamped, the plate may become loose or offset. The clamping mechanism can apply corresponding pressure to plates of different thicknesses by adjusting the clamping force.

[0030] Example 2

[0031] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the fixing component 3 includes a duckbill clamp 31, a T-block 32 is arranged on the side of the duckbill clamp 31, the number of the T-blocks 32 is two, a spring 33 is fixed between the two T-blocks 32, a sliding groove 34 is opened on the inner side of the clamping mechanism body 1, and the T-block 32 is movably clamped in the sliding groove 34.

[0032] In this embodiment, the plate is first placed in the duckbill clamp 31. According to the different thicknesses of the plates, when the plates pass through the inclined surface at the front end of the duckbill clamp 31, the duckbill clamp 31 uses the spring 33 in the T-block 32 to move the T-block 32 backward in the sliding groove 34, so that the duckbill clamp 31 can tightly fix and position the plates, so that when the plates enter the conveyor belt 53, the position of the plates is shifted, thereby avoiding damage to the plates by the clamping component 2. By setting the fixing component 3, the problem of positional shift of plates of different thicknesses when entering the clamping mechanism is solved, thereby achieving the effect of positioning and clamping plates of different thicknesses when entering the clamping mechanism.

[0033] Working principle: In this embodiment, the plate after sanding is first passed through the fixing assembly 3. According to the thickness of the plate, the duckbill clamp 31 causes the T-block 32 to slide in the sliding groove 34 in reverse through the spring 33, so that the duckbill clamp 31 is opened to both sides to a position suitable for the thickness of the plate, and the plate is positioned and fixed. The conveyor belt 53 is driven to rotate by the output end of the second servo motor 51, so that the plate moves toward the clamping mechanism under the rotation of the conveyor belt 53. When the plate completely passes through the duckbill clamp 31, the front end of the plate senses the clamping force of the plate through the pressure sensor 24 on the side of the support plate 23, and the pressure is displayed on the display screen 27. The staff then adjusts the clamping assembly 2 to clamp the plate In order to increase the clamping force of the plate, the clamping component 2 will drive the gear 43 to mesh and move up and down in the rack 42 through the output end of the first servo motor 45, so that the support rod 44 can adjust the height up and down, so that the clamping wheel 26 can apply a clamping force corresponding to the thickness of the plate, which solves the problem that the pressure of the existing clamping mechanism is constant and cannot be adjusted. When a thicker plate is clamped, the plate may be subjected to a greater pressure and an indentation may appear on the surface of the plate. When a thinner plate is clamped, the plate may become loose or shifted. By setting two clamping components 2, the clamping of both sides of the plate is more stable, preventing the position of the plate from shifting during the clamping process.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
