Problems solved by technology

[0004] In order to solve the above problems, the friction between the sandpaper belt and the wood produces a large amount of heat during the working process, causing the maximum static friction force between the sandpaper belt and the pulley to become smaller after the sandpaper belt is heated and elongated, causing the pulley and the sandpaper belt to slip easily, which affects the leveling and polishing efficiency of the wood. problem, the present invention provides a belt smoother pulley device that is convenient for adjusting the tension of the sandpaper belt

Embodiment １

[0023] Figure 1 and figure 2 , the abrasive belt smoother pulley device that is convenient for adjusting the tension of the sandpaper belt provided by the present invention includes a frame 3, and a brake box 2 is fixedly connected to the frame 3, and a brake box 2 is arranged in the brake box 2. Braking device, the output end of the braking device is connected to the driving pulley 1, and also includes an adjusting part 6, two movable struts 5 parallel to each other and a first driven wheel 4, and the adjusting part 6 is fixedly connected to the frame 3 , the adjustment part 6 is provided with a through hole, and the through hole is provided with a rotating shaft 62 that is in clearance fit with it. Tighten the bolt 61, one end of the movable strut 5 is fixedly connected to the rotating shaft 62, the first driven wheel 4 includes a roller part and a central shaft connected to the roller part, and the central shaft is hinged to any movable strut 5 Connected, the central axis...

Embodiment 2

[0027] This embodiment is further limited on the basis of embodiment 1: as shown in Figure 1 and figure 2The movable strut 5 fixedly connected with the central shaft is provided with an adjusting bolt 9 threaded therewith, and the end of the threaded section of the adjusting bolt 9 is ball-connected with the central shaft. The above structural form is simple, the ball connection is located at the end of the threaded section of the adjusting bolt 9, by rotating the adjusting bolt 9, the position of the end of the threaded section of the adjusting bolt 9 relative to the movable strut 5 is changed, so as to change the inclination of the first driven wheel 4 the goal of. Further, in order to simplify the above-mentioned structure, the deformation caused by the belt pulley during the transmission process of the sandpaper belt 8 is uniform and excessive, so as to prolong the life of the sandpaper belt 8, the axis of the adjusting bolt 9 is connected with the movable strut threadedl...

Embodiment 3

[0030] This embodiment is further limited on the basis of embodiment 1: as shown in Figure 1 and figure 2 , to uniformly bear the force on the sandpaper belt 8 along its width direction, the axes of the first driven pulley 4 and the driving pulley 1 are parallel.

[0031] It also includes a second driven wheel 7, which is fixedly connected to the frame 3, and the second driven wheel 7, the driving pulley 1 and the first driven wheel 4 are not on the same straight line. In the above setting, because the second driven wheel 7 and the position of the driving pulley 1 are fixed, that is, the position of the sandpaper belt 8 between the second driven wheel 7 and the driving pulley 1 is fixed, it is convenient to connect the second driven wheel 7 with the driving pulley. 1 is set as the working area. Further, the axes of the second driven pulley 7 and the driving pulley 1 are located on the same horizontal plane, which facilitates obtaining a flat and flat polishing working plane,...

Abstract

The invention discloses a sand paper belt leveling machine belt wheel device capable of conveniently adjusting the tightness of a sand paper belt. The sand paper belt leveling machine belt wheel device comprises a machine frame, an adjustment part, two parallel movable supporting rods and a first driven wheel. A brake box is fixedly connected to the machine frame and provided with a brake device inside. The output end of the brake device is connected with a driving belt wheel. The adjustment part is fixedly connected to the machine frame and provided with a through hole, a rotating shaft in clearance fit with the through hole is arranged in the through hole, an internal thread through hole is formed in the side wall of the through hole, an abutting bolt matched with the internal thread through hole in a threaded mode is arranged in the internal thread through hole, one end of each movable supporting rod is fixedly connected to a rotating shaft, a center shaft is connected with one movable supporting rod in a hinged mode and is fixedly connected with the other movable supporting rod, and the position of the joint of the center shaft and the other movable supporting rod is adjustable. The sand paper belt leveling machine belt wheel device is simple in structure, the tightness of the sand paper belt can be conveniently adjusted, sliding between the belt wheels and the sand paper belt is avoided, wood material leveling and polishing efficiency is improved, and the tightness in the width direction of the sand paper belt can be conveniently adjusted.

Description

technical field [0001] The invention relates to a wood leveling device, in particular to a pulley device of an abrasive belt leveler which is convenient for adjusting the tension of the sandpaper belt. Background technique [0002] Wooden panels have the advantages of light weight, high strength ratio, good elasticity, impact resistance, rich and beautiful textures and colors, and easy processing. At the same time, they are resource-renewable. Wooden panels have played an important role in the national economy since ancient times. The wood panel processing industry uses wood panels as raw materials and mainly processes them mechanically. [0003] In order to make wooden products more beautiful, the outer surface of the existing wooden boards often needs to be smoothed and polished. In the prior art, a ring-shaped sandpaper belt has appeared. The sandpaper belt is wound on the pulley and rotates with the pulley at high speed to efficiently clean the wood The surface of the w...
