Description

Technical Field

[0001] The utility model belongs to the technical field of surface processing of curved cabinet doors, and particularly relates to a polishing device for surface processing of curved cabinet doors. Background Art

[0002] In today's furniture manufacturing industry, curved cabinet doors are widely loved by consumers for their unique shape and graceful curves, which can add artistic and decorative elements to furniture. However, the production process of curved cabinet doors, especially the surface processing, faces many technical difficulties.

[0003] Traditional polishing devices for cabinet door surface processing have obvious limitations when it comes to curved cabinet doors. Most previous devices were designed based on the processing requirements of flat cabinet doors, and their structure and functions are not well adapted to the special shape of curved cabinet doors.

[0004] A common problem is that these devices typically only polish a specific surface of the door, preventing simultaneous processing of both the sides and back. This makes the polishing process for curved doors cumbersome and inefficient, requiring multiple operations for each surface. This not only consumes considerable time and labor, but also makes it difficult to ensure consistent and coordinated treatment across all surfaces.

[0005] Furthermore, because curved doors vary in their curvature and form, traditional polishing equipment struggles to adapt to these varying curvatures. They can't flexibly adjust the position and angle of the polishing components to the specific curvature of the door, resulting in inadequate contact between the polishing components and the door surface, impacting polishing quality and accuracy.

[0006] Furthermore, some existing polishing devices do not fix the cabinet doors firmly and accurately enough during operation, which may cause the cabinet doors to shift or shake during the processing, thereby affecting the accuracy of polishing and the quality of the finished product.

[0007] At the same time, traditional devices may have problems such as unstable mechanical transmission and uneven grinding force during operation, resulting in poor polishing effect and even damage to the cabinet door surface.

[0008] To this end, we propose a polishing device for surface processing of curved cabinet doors. The device can not only adapt to curved cabinet doors of different shapes, but also polish the sides and backs of the curved cabinet doors at the same time, thereby improving the polishing efficiency.

[0026] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0027] like Figure 1-4As shown, the technical solution adopted in this utility model is specifically as follows: a polishing device for surface processing of curved cabinet doors, comprising a workbench 1, a rotating component and a fixing component for fixing the curved cabinet door are arranged on the top of the workbench 1, a first connecting plate 2 is fixed on the top of the rotating component, a first fixing plate 3 is fixed on the side of the first connecting plate 2 facing the cabinet door, a first elastic component is arranged on the first fixing plate 3, a first supporting plate 4 is arranged on the first elastic component, a side grinding component is arranged on the first supporting plate 4, and a third fixing plate 21 is fixed on the top of the first connecting plate 2, a second fixing plate 5 is fixed on the bottom of the third fixing plate 21, a second elastic component is arranged on one side of the second fixing plate 5, a second support plate 6 is arranged on the second elastic component, and a back grinding component is arranged on the second support plate 6.

[0028] In this embodiment, the fixing assembly includes four fixing rods 7 fixed on the top of the workbench 1. A telescopic cylinder 8 is provided on the top of each fixing rod 7. The telescopic end of the telescopic cylinder 8 is hinged to a fourth fixing plate 9.

[0029] Four fixing rods 7 are arranged on the top of the workbench 1. They not only provide a stable support for the entire fixing assembly, but also ensure that the curved cabinet door can maintain a stable position during the polishing process. A telescopic cylinder 8 is fixed to the top of each fixing rod 7. The design of these cylinders allows their telescopic ends to be adjusted to accommodate curved cabinet doors of different sizes and shapes. When the telescopic cylinders 8 are working, they will provide the necessary tightening force to ensure that the curved cabinet door does not move or shake during the processing. The telescopic end of the telescopic cylinder 8 is connected to the fourth fixing plate 9 by a hinge. This design allows the fourth fixing plate 9 to be fine-tuned on the surface of the curved cabinet door to ensure a close fit with the cabinet door. When the telescopic cylinder 8 applies force, the fourth fixing plate 9 will press the curved cabinet door more firmly to prevent it from shifting during the polishing process.

[0030] At the same time, each fourth fixing plate 9 is provided with an anti-slip surface, which can improve the limiting ability of the fourth fixing plate 9 on the cabinet door when fixed.

[0031] Its working principle is as follows: first, the curved cabinet door is placed on the workbench 1, and then the side grinding assembly and the back grinding assembly are rotated by the rotating assembly, so that the curved cabinet door is located between the side grinding assembly and the back grinding assembly, and then the curved cabinet door is fixed by the fixing assembly, and then the side grinding assembly and the back grinding assembly are started, so that the side and back of the curved cabinet door are ground at the same time, and then after the grinding of one area is completed, the side grinding assembly and the back grinding assembly are moved to the next area for grinding, and at the same time, the first elastic assembly and the second elastic assembly are used to adapt to the different curvatures of the curved cabinet door, so that the side grinding assembly and the back grinding assembly are respectively fitted with the side and back of the curved cabinet door, so as to perform grinding. This device can not only adapt to curved cabinet doors of different curvatures, but also can grind the side and back of the curved cabinet door at the same time, thereby improving the grinding efficiency.

[0032] In one embodiment of the present invention, the rotating assembly includes a stepper motor 10 fixed to a workbench 1. A rotating shaft is mounted on the output end of the stepper motor 10, the top of which is fixedly connected to the first connecting plate 2. The stepper motor 10 drives the rotating shaft to cause the first connecting plate 2 to perform stepping motion, thereby allowing each area of ​​the curved cabinet door to be polished.

[0033] The first elastic component includes a first sliding groove 11 opened on the first fixed plate 3, a first fixed shaft 12 is fixed inside the first sliding groove 11, a first slider 13 and a first spring 14 are sleeved on the first fixed shaft 12, one side of the first slider 13 is connected to the first spring 14, and the bottom of the first slider 13 is connected to the first support plate 4.

[0034] In one embodiment of the present invention, the first slider 13 is constrained within the first chute 11 or the first fixed shaft 12 and the first slider 13 are configured to form a rectangular cross-section to prevent the first slider 13 from rotating about the first fixed shaft 12. The second slider is constrained within the second chute or the second fixed shaft and the second slider are configured to form a rectangular cross-section to prevent the second slider from rotating about the second fixed shaft 12.

[0035] When the curved cabinet door is placed on the polishing device and polished, the side polishing assembly will be subjected to a reaction force from the cabinet door surface. This reaction force will be transmitted to the first slider 13 through the first support plate 4 connected thereto, causing the slider to slide along the first fixed axis 12 in the first slide groove 11. As the first slider 13 slides, the elastic force generated by the first spring 14 will offset part or all of the reaction force from the cabinet door surface, ensuring that the side polishing assembly can maintain stable contact and pressure with the cabinet door surface. Due to the elastic action of the first spring 14, even if the shape or size of the cabinet door changes, the side polishing assembly can adaptively adjust its position to maintain a close fit with the cabinet door surface, thereby adapting to the shapes of different curved cabinet doors.

[0036] Similarly, the second elastic component includes a second slide groove 15 opened on the second fixed plate 5, a second fixed shaft 16 is arranged inside the second slide groove 15, a second slider 17 and a second spring 18 are sleeved on the second fixed shaft 16, one side of the second slider 17 is connected to the second spring 18, and the bottom of the second slider 17 is connected to the second support plate 6.

[0037] When the curved cabinet door is placed on the polishing device and polished, the back polishing assembly connected to the second support plate 6 will be subjected to a reaction force from the cabinet door surface or other components inside the device. This reaction force will be transmitted to the second slider 17 through the second support plate 6, causing the second slider 17 to slide along the second fixed axis 16 in the second slide groove 15. As the second slider 17 slides, the second spring 18 will be compressed or stretched. The elastic force of the second spring 18 will offset part or all of the reaction force from the cabinet door surface or other components inside the device, ensuring that the polishing assembly connected to the second support plate 6 can maintain a stable position and state. Due to the elastic action of the second spring 18, even if the shape, size or force of the cabinet door changes during the polishing process, the back polishing assembly can adaptively adjust its position to maintain a close fit with the cabinet door surface, thereby adapting to the shapes of different curved cabinet doors.

[0038] The side grinding assembly and the back grinding assembly both include a motor 19 arranged on the first support plate 4 and the second support plate 6. The output end of the motor 19 is equipped with a grinding roller 20, which is driven by the motor 19 to grind the sides and back of the curved cabinet door.

[0039] When working, when the whole device rotates to Figure 1 When the cabinet door is curved and concave as shown, the first spring 14 is in an elastically released state, and the second spring 18 is in an elastically compressed state. This is because the relative positions of the various components change during the rotation of the device, resulting in changes in the direction and magnitude of the forces acting on the first spring 14 and the second spring 18. Specifically, the rotation of the device causes the first slider 13 connected to the first spring 14 to be subjected to a force that moves it away from the first fixed axis 12. Therefore, the first spring 14 is recovering to its original shape after being stretched or compressed, releasing the elastic potential energy stored before, and showing an elastically released state. At the same time, the rotation of the device causes the second slider 17 connected to the second spring 18 to be subjected to a force that moves it toward the second fixed axis 16. This force causes the second spring 18 to be compressed, storing elastic potential energy, and showing an elastically compressed state, as shown in FIG. Figure 2 As shown, when the first spring 14 is rotated to other positions, it is in a compressed state, and the second spring 18 is in an elastically released state.

[0040] The working principle of the present invention is as follows: first, the curved cabinet door is placed on the workbench 1, and then the side grinding assembly and the back grinding assembly are rotated by the rotating assembly, so that the curved cabinet door is located between the grinding rollers 20 of the side grinding assembly and the back grinding assembly, and then the telescopic cylinder 8 is extended, and the paired fourth fixing plates 9 fix the curved cabinet door, and then the side grinding assembly and the back grinding assembly are started, so that the side and back of the curved cabinet door are simultaneously ground, and then after the grinding of one area is completed, the side grinding assembly and the back grinding assembly are moved to the next area for grinding, and at the same time, the first elastic assembly and the second elastic assembly are used to adapt to the different curvatures of the curved cabinet door, so that the side grinding assembly and the back grinding assembly are respectively fitted with the side and back of the curved cabinet door, so as to perform grinding. The device can not only adapt to curved cabinet doors of different curvatures, but also can grind the side and back of the curved cabinet door at the same time, thereby improving the efficiency of grinding.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
