Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sanding machines, in particular to a sanding machine roller with an anti-static structure. BACKGROUND

[0002] A sanding machine is a mechanical device for polishing and polishing the surface of wood, metal or other materials. When the sanding machine belt, sand wheel or roller is in contact with the surface of the object, the friction generated by the high-speed rotation can remove burrs, flaws and other defects on the surface of the object, so as to achieve a smooth and flat effect.

[0003] For example, a durable vertical sanding machine roller with publication number CN221416171U is provided with a sliding block, a penetrating rod, a lifting plate and a first screw rod. By rotating the first screw rod, the first screw rod drives the lifting plate to lift, so that the two penetrating rods drive the two sliding blocks to lift up and down, thereby adjusting the horizontal height of the roller from the upper surface of the feeding roller, facilitating the sanding of the roller on workpieces of different thicknesses, and the operation is simple and convenient.

[0004] However, as shown in the description and drawings of the above-mentioned scheme, when the roller is cleaned by the brush layer and the roller and the workpiece are in high-speed friction, a large amount of electric charge is easily accumulated on the roller, thereby inducing static electricity, which adversely affects the equipment and the user.

[0005] Therefore, the application provides a sanding machine roller with an anti-static structure to meet the needs. CONTENT OF THE UTILITY MODEL

[0006] Therefore, the purpose of the application is to provide a sanding machine roller with an anti-static structure to reduce the accumulation of electric charge on the sanding machine roller and reduce the adverse effects of static electricity.

The driving member is installed on one side of the frame. The driving member and the roller have a transmission relationship. The side of the frame is also provided with an anti-static assembly. The anti-static assembly comprises a grounding rod, a sleeve and a connecting rod. The grounding rod is installed on the other side wall of the frame. The sleeve is slidably connected to the outside of the grounding rod. The connecting rod is rotatably connected to the outside of the sleeve.

[0009] The side wall of the frame is provided with a strip-shaped hole. The connecting rod penetrates through the strip-shaped hole of the side wall of the frame. The connecting rod is arranged directly above the roller.

[0010] Preferably, the end of the roller is provided with a slope, and the end surface of the connecting rod abuts against the end slope of the roller.

[0011] Preferably, the lower end surface of the grounding rod is arranged at the same height as the lower surface of the rack.

[0012] Preferably, the top of the rack is provided with a support, the bottom of the support is provided with a connecting seat, a conveying roller is connected between two same-side connecting seats, a screw rod is penetrated through the center of the support, and the other end of the screw rod is rotationally connected to the center of the top of the rack.

[0013] Preferably, the distance between two opposite connecting seats is greater than the diameter of the roller.

[0014] Preferably, the outer side wall of the connecting seat is attached to the vertical side wall of the rack.

[0015] Preferably, the conveying roller is rotationally connected to the middle position of the side wall of the connecting seat.

[0016] Compared with the prior art, the application has at least the following beneficial effects:

[0017] In the above scheme, by arranging the grounding rod, the sleeve and the connecting rod, the electric charge gathered on the surface of the roller is transferred to the sleeve and the grounding rod in sequence through the connecting rod, so that the static electricity is released to the ground, thereby reducing the situation that the electric charge is gathered on the roller of the sander and reducing the adverse effects caused by static electricity.

[0018] In the above scheme, by arranging the support, the connecting seat, the conveying roller and the screw rod, the distance between the conveying roller and the roller can be adjusted by rotating the screw rod, so that the machining of workpieces of different thicknesses can be adapted, and the machining of multiple surfaces of the workpieces can be conveniently and quickly realized.
