Description

Technical Field

[0001] The utility model relates to the technical field of belt sanders, in particular to a belt sander that can increase the grinding depth. Background Art

[0002] A belt sander is a processing device widely used in modern manufacturing, mainly for grinding and polishing the surfaces of various materials to achieve the required surface roughness and processing quality. This device is of great significance for improving production efficiency and processing quality. However, although the existing belt sander designs allow users to adjust the angle of the sanding belt to adapt to different workpiece shapes and requirements, they usually lack a depth adjustment function.

[0003] In practical applications, especially when the workpiece surface is designed with specific grooves or complex contours, simple angle adjustment is often insufficient to provide effective processing. At this time, if the belt sander can simultaneously adjust the working depth of the sanding belt, it will greatly improve the processing adaptability and accuracy. Most belt sander devices on the current market lack this depth adjustment function, resulting in the need to supplement with other mechanical equipment for preprocessing or reprocessing when dealing with workpieces with complex grooves. This not only increases the complexity of the process but also prolongs the time of the entire production process and reduces work efficiency.

[0004] Therefore, developing a belt sander with a depth adjustment function is of great practical significance for simplifying the production process, improving processing accuracy, and flexibly dealing with complex workpieces. Summary of the Utility Model

[0005] The utility model discloses a belt sander that can increase the grinding depth, aiming to solve the technical problem that when dealing with workpieces with complex grooves, it is necessary to supplement with other mechanical equipment for preprocessing or reprocessing.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A belt sander that can increase the grinding depth includes a housing. A chassis is movably connected to the outside of the housing. Below the chassis, there is a sanding belt housing and a sanding belt covering it. Two first inclined grooves are symmetrically opened on the housing. A rotating shaft is arranged below the right side of the housing and is used in cooperation with the lower right side of the housing. A turning plate is connected to the outer surface of the rotating shaft, and the front end of the sanding belt can be fully exposed for in-depth grinding by flipping the turning plate. There is a groove on the upper surface of the turning plate.

[0008] By moving the chassis, the bending block is brought into contact with the first inclined groove and the second inclined groove, so that the position of the housing can be controlled, and the housing can be raised or lowered, thereby achieving the purpose of adjusting the grinding depth.

[0009] In a preferred embodiment, a contact groove is provided on the outer shell, and a connecting plate is fixedly connected to the chassis.

[0010] In a preferred embodiment, a first handle is provided on the outer shell, and a second handle is provided on the outer shell on one side of the first handle. The first handle and the second handle are arranged in a cross structure.

[0011] By arranging the first handle and the second handle in a cross structure, it is convenient for the user to grasp with both hands.

[0012] In a preferred embodiment, a cable connection end is connected to the outer shell. The cable connection end is made of rubber and has a hollow structure.

[0013] Connect the cable through the cable connection end to supply power to the device.

[0014] In a preferred embodiment, the chassis is arranged in a rectangular structure. Four bending blocks are symmetrically arranged on the chassis. The bending blocks are set at 90 degrees. The bending blocks are all located inside and slidably connected to the corresponding first inclined groove and second inclined groove. Two second inclined grooves are symmetrically opened on the outer shell on one side of the first inclined groove. The first inclined groove and the second inclined groove are arranged in a parallel structure.

[0015] The belt sander provided by the present utility model that can increase the grinding depth has the following advantages:

[0016] In the present utility model, the movement of the top plate further causes contact with the contact groove, realizing the front-back adjustment of the outer shell. In addition, by moving the chassis, the bending blocks are in contact with the first and second inclined grooves, effectively controlling the position of the outer shell to perform the rising or falling operation. This design effectively achieves the purpose of adjusting the grinding depth, providing a simple and efficient method to adjust the working state of the device to adapt to processing tasks with different height or depth requirements, greatly improving the flexibility and applicability of processing. Through this mechanism, the processing process can be more precisely controlled, thereby improving product quality and work efficiency, reducing the dependence on other auxiliary equipment. At the same time, a rotatable turning plate is added, so that there is an extra section of the sand belt, which can grind the corner area, improving the practical performance. The added turning plate can penetrate into special areas for grinding. BRIEF DESCRIPTION OF THE DRAWINGS
