Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a mobile belt sander. Background Technology

[0002] In machining, hardware manufacturing, and other fields, belt sanders are widely used as key processing equipment in the manufacturing processes of various products. Especially in deburring, flash removal, and polishing, belt sanders have become indispensable tools due to their high grinding efficiency and good processing quality. However, in practical applications, traditional belt sanders often rely on manual hand-held movement. While this method can meet basic sanding needs to some extent, it has several shortcomings. First, when manually moving the sander, uneven force control by the operator can easily lead to uneven force distribution during the sanding process, affecting the quality and effect. This uneven force distribution is particularly prominent when dealing with high-precision or fragile mechanical instruments or parts, often causing damage to the instruments or parts being sanded. Second, manually moving the sander is time-consuming, labor-intensive, and inefficient. Especially in production environments requiring a large number of sanding operations, this manual operation method often cannot meet the demands of high-efficiency production. In addition, prolonged hand-held sanding work can easily put physical strain on operators and increase the risk of workplace injuries. Utility Model Content

[0003] To address the problem of uneven force distribution and reduced grinding quality caused by manually moving the grinding machine in the prior art, this utility model provides a mobile belt sander.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A mobile belt sander includes a housing, a grinding wheel, a transmission mechanism, a grinding wheel motor, a chassis, a guide rail, and a guide rail motor. The housing is mounted on the chassis and is a right-angled trapezoid with an open upper base. A surface of the trapezoid perpendicular to the upper base contacts the chassis. The grinding wheel motor is located outside the housing. The grinding wheel is positioned at the opening of the housing, with a portion inside the housing and a portion outside. The transmission mechanism is located inside the housing and includes multiple pulleys, a belt, and bearings. The belt connects the pulleys, one pulley is connected to the central shaft of the grinding wheel via a bearing, and another pulley is connected to the output shaft of the grinding wheel motor. The chassis is mounted on the guide rail, with a groove at the bottom matching the guide rail. The guide rail connects to the guide rail motor.

[0006] Furthermore, the grinding wheel is equipped with a detachable abrasive belt.

[0007] Furthermore, the guide rail is a T-shaped or U-shaped guide rail.

[0008] Furthermore, the outer surface of the housing is also equipped with a control system for the grinding wheel motor, which includes a frequency converter, sensors, and a control panel.

[0009] Furthermore, the opening of the housing is provided with an adjustable protective cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model provides a mobile belt sander. Through the design of the chassis and guide rails, the belt sander can move flexibly in different working areas. The bottom of the chassis is designed with grooves that match the guide rails, ensuring the stability of the sander during movement and preventing a decrease in sanding quality due to shaking or deviation. The automated and mechanized design greatly reduces the operator's labor intensity. The operator only needs simple controls to move the sander and rotate the grinding wheel, eliminating the need for handheld operation or manual movement. This not only optimizes the operation process and reduces fatigue and the risk of work-related injuries caused by prolonged handheld use, but also avoids the problem of poor sanding quality and effect due to uneven operator force control.
