Description

Technical Field

[0001] This utility model is a sanding device for wooden furniture boards, belonging to the field of board sanding technology. Background Technology

[0002] Sanding is an essential step in the manufacturing process of wooden furniture panels. Sanding removes burrs and uneven areas from the surface of the panels, improving their smoothness and preparing them for subsequent processes such as coating. Traditional manual sanding is inefficient and inconsistent in quality, so various automated or semi-automated sanding devices have emerged. Current sanding devices include stationary belt sanders, manual sanders, or semi-automatic conveyor sanders.

[0003] However, manual sanders rely on the operator's experience to control the pressure, which is labor-intensive and carries a high risk of dust inhalation (PM2.5 concentration > 500 μg / m³). There is an urgent need for a sanding device for wooden furniture boards to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wood furniture board sanding device to solve the problems mentioned in the background technology. This utility model adopts a labor-saving downward pressure buffer moving structure to realize labor-saving sanding of boards, and is equipped with a detachable suction structure that can suck up most of the dust generated during sanding, ensuring the quality of the environment in which the sanding personnel are located.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wood furniture board sanding device, including a top plate and a baffle plate. Multiple vertical rods are longitudinally welded to the lower end of the top plate, and a baffle plate is horizontally welded to the lower end of each of the vertical rods. A sanding motor is installed on the upper end of the baffle plate. Sleeves are threadedly fixed to the outside of each of the vertical rods. Hollow cylinders are longitudinally glued to the lower outer ends of each of the sleeves. Multiple return springs and multiple buffer rods are longitudinally installed inside each of the hollow cylinders. A corrugated sleeve is glued to the lower edge of the baffle plate with hot melt adhesive. A counterweight ring is glued to the lower edge of the corrugated sleeve. A bent tube head is welded through the upper left front side of the baffle plate. A filter element is inserted into the bent tube head. The discharge end of the bent tube head is magnetically attracted and fixed to a strong magnetic ring. A connecting hose is glued to the other end of the strong magnetic ring.

[0006] Furthermore, a handle is attached to the upper end of the top plate.

[0007] Furthermore, a grinding head is mounted on the end of the grinding motor shaft.

[0008] Furthermore, the lower ends of the plurality of reset springs are welded and fixed to the plurality of buffer rods respectively.

[0009] Furthermore, the lower ends of each of the buffer rods are fitted with universal ball bearings.

[0010] Furthermore, the other end of the connecting hose is connected to a vacuum cleaner.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a wood furniture board sanding device. Because it adds a sanding motor, upright rod, sleeve rod, hollow cylinder, return spring, buffer rod, universal ball bearing, baffle, corrugated sleeve, counterweight ring, bending pipe head, filter element, strong magnetic ring, connecting hose and vacuum cleaner, our design improvements and actual use show that this device has a reasonable structure and good practicality. It adopts a labor-saving downward pressure buffer moving structure to achieve labor-saving sanding of boards, and is equipped with a detachable suction structure that can suck up most of the dust generated during sanding, ensuring the quality of the environment in which the sanding personnel are located.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a wood furniture board sanding device, including a top plate 2 and a baffle plate 11. Multiple uprights 5 are longitudinally welded to the lower end of the top plate 2, and the baffle plate 11 is horizontally welded to the lower end of the multiple uprights 5. A sanding motor 3 is installed on the upper end of the baffle plate 11. Sleeve rods 6 are threadedly fixed to the outside of the multiple uprights 5. Hollow cylinders 7 are longitudinally glued to the lower outer side of the multiple sleeve rods 6. Multiple return springs 8 and multiple buffer rods 9 are longitudinally installed inside the multiple hollow cylinders 7. A corrugated sleeve 12 is glued to the lower edge of the baffle plate 11 by hot melt adhesive. A counterweight ring 13 is glued to the lower edge of the corrugated sleeve 12. A bent tube head 14 is welded through the upper left front side of the baffle plate 11. A filter element 15 is inserted into the bent tube head 14. The discharge end of the bent tube head 14 is magnetically attracted and fixed to a strong magnetic ring 16. A connecting hose 17 is glued to the other end of the strong magnetic ring 16. This design solves the problems of high labor intensity and high risk of dust inhalation when using manual sanders for the original boards.

[0020] As the first embodiment of this utility model: a handle 1 is glued to the upper end of the top plate 2, which makes it easier for the grinder to hold the device. A grinding head 4 is installed on the shaft end of the grinding motor 3, and the lower ends of multiple return springs 8 are welded and fixed to multiple buffer rods 9 respectively. By welding and fixing the lower ends of multiple return springs 8 to multiple buffer rods 9 respectively, the multiple buffer rods 9 can be prevented from sliding and falling off inside the multiple hollow cylinders 7.

[0021] Multiple buffer rods 9 have universal ball bearings 10 glued to their lower ends. These ball bearings 10 can roll on the wooden furniture board to be sanded, thus assisting the movement and sanding of this device. The other end of the connecting hose 17 is connected to a vacuum cleaner 18. The vacuum cleaner 18 can suck up and filter the dust in the corrugated sleeve 12 through the connecting hose 17, the filter element 15, and the bent tube head 14.

[0022] As a second embodiment of this utility model: the device is placed on the wooden furniture board to be sanded. During this process, multiple universal ball bearings 10 slide directly in contact with the upper surface of the wooden furniture board to be sanded, and the counterweight ring 13 contacts the upper surface of the wooden furniture board, causing the corrugated sleeve 12 to be pulled downward, blocking the sanding head 4. Pressing the handle 1 allows the top plate 2 and multiple uprights 5 to apply force to the baffle 11, thereby causing multiple buffer rods 9 to press upward against multiple return springs 8, and the corrugated sleeve 12 to be slightly compressed, making the sanding head 4 fit against the upper surface of the wooden furniture board to be sanded. The sanding motor 3 is then started, and the sanding motor 3 drives the sanding head to be sanded. The grinding head 4 can be rotated to grind the surface of the wooden furniture board. When the handle 1 is pulled left and right, multiple universal balls 10 can slide on the surface of the wooden furniture board, allowing the grinding head 4 to change position and grind the rest of the surface of the wooden furniture board. During this process, the vacuum cleaner 18 is started. The vacuum cleaner 18 can suck up the dust in the corrugated sleeve 12 through the connecting hose 17 and the bent tube head 14. The filter element 15 intercepts and filters the sucked-up dust. After use, the strong magnetic ring 16 is pulled off forcefully to separate the bent tube head 14 from it, and the filter element 15 can be pulled out for cleaning.
