[0005] Its drawback is that the belt sander is not suitable for performing standardized operations on multiple workpieces at the same time, resulting in low machine efficiency and low production capacity.

[0006] Therefore, existing technologies need to be improved. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0041] Please see Figure 1 This embodiment provides a four-station belt sander, which includes: a main body 100, a plurality of parallel polishing wheels 300 and a plurality of rollers 400. The main body 100 includes a first sanding belt 200. The polishing wheels 300 are rotatably disposed on the main body 100, and the rollers 400 are rotatably disposed on the main body 100. The first sanding belt 200 is wound between the polishing wheels 300 and the rollers 400, and the rollers 400 and the polishing wheels 300 are spaced apart, so that the first sanding belt 200 forms a plurality of V-shaped grinding platforms arranged in a straight line.

[0042] In this embodiment, the main body 100 may have a motor that can drive the first sanding belt 200 to rotate. The polishing wheel 300 supports the first sanding belt 200 and the first sanding belt 200 at the position of the polishing wheel 300 is in direct contact with the workpiece for polishing the workpiece. For example, the workpiece can be clamped by a robot arm, which can swing around the polishing wheel 300, so that the polishing wheel 300 abuts against the side of the workpiece via the first sanding belt 200. This is applicable to irregularly shaped workpieces, such as workpieces with curved surfaces, such as flanges or circular workpieces.

[0043] In this embodiment, the first abrasive belt 200 is supported by a roller 400 in conjunction with a polishing wheel 300. The roller 400 and the polishing wheel 300 are spaced apart; for example, a roller 400 is positioned between two polishing wheels 300. The polishing wheel 300 abuts against the first abrasive belt 200, causing the first abrasive belt 200 to bulge outwards. The roller 400 abuts against the first abrasive belt 200, causing the first abrasive belt 200 to be recessed towards one side of the roller 400. That is, a concave "V"-shaped first abrasive belt 200 is wound between the two polishing wheels 300. Thus, at the position of the polishing wheel 300... The first abrasive belt 200 is formed by placing a convex "V" shape. Multiple concave "V" shaped first abrasive belts 200 and multiple convex "V" shaped first abrasive belts 200 are connected in sequence to form multiple V-shaped grinding platforms arranged in a straight line. One convex "V" shaped first abrasive belt 200 is equivalent to one grinding station, that is, one wave is equivalent to one grinding station. One grinding station can correspond to grinding one workpiece. Multiple convex "V" shaped first abrasive belts 200 can realize multiple grinding stations to process multiple workpieces at the same time. Therefore, the processing efficiency is high.

[0044] The mounting structure of polishing wheel 300 and roller 400 can be understood as existing technology and will not be described in detail.

[0045] In the prior art, a belt sander usually has one grinding station, while in this embodiment, multiple grinding stations can be set up without changing the overall size of the belt sander, which can save equipment space.

[0046] Therefore, in this embodiment, the first sanding belt 200 is supported by the roller 400 and the polishing wheel 300, so that the first sanding belt 200 forms multiple V-shaped grinding platforms arranged in a straight line. One wave is equivalent to one grinding station, which can realize the simultaneous processing of multiple grinding stations, resulting in high processing efficiency and full utilization of the base equipment space.

[0047] Specifically, please refer to Figure 1 The main body 100 has a proximal end 101 and a distal end 102. Several polishing wheels 300 are located at the distal end 102, and a roller 400 is located at the proximal end 101. The roller 400 is located between two polishing wheels 300. The roller 400 is used to cooperate with the polishing wheels 300 to support the first sanding belt 200, so that the first sanding belt 200 forms multiple V-shaped grinding platforms arranged in a straight line.

[0048] In this embodiment, several parallel polishing wheels 300 are located at the distal end 102, and the roller 400 is located at the proximal end.

[0049] 101, and the roller 400 and the polishing wheel 300 are spaced apart, so that the first sanding belt 200 forms several convex "V" shaped first sanding belts 200 on the polishing wheel 300. The convex "V" shaped first sanding belts 200 are equivalent to a grinding station, thereby enabling multiple grinding stations to process at the same time.

[0050] Specifically, please refer to Figure 1 Several polishing wheels 300 are arranged in parallel at equal intervals.

[0051] For example, several polishing wheels 300 are arranged at equal intervals, which makes the convex "V"-shaped first sanding belt 200 also equidistant, enabling several grinding stations to process simultaneously and improving work efficiency.

[0052] Specifically, please refer to Figure 1 Several polishing wheels 300 are arranged in a straight line.

[0053] For example, several polishing wheels 300 are arranged in a straight line, so that the crests of the convex "V"-shaped first abrasive belt 200 are also arranged in a straight line, which is equivalent to several grinding platforms being arranged in a straight line. When several workpieces are processed at the same time, several workpieces can be ground and processed simultaneously.

[0054] Optionally, the number of polishing wheels 300 is set to 4.

[0055] For example, setting the number of polishing wheels 300 to four allows for efficient use of equipment space and saves space. Generally, conventional belt sanders have a single grinding station on the base, resulting in low efficiency and a large footprint. While two or three polishing wheels 300 could be used, this doesn't fully utilize the space. Alternatively, five polishing wheels would increase the overall size of the belt sander. Therefore, in this embodiment, four polishing wheels 300 are used to maximize the utilization of the base space without changing the existing belt sander base. It should be understood that the number of polishing wheels 300 is not limited to four; other configurations are possible and not restricted here.

[0056] Optionally, the number of rollers 400 is set to 3, and the 3 rollers 400 are arranged in a straight line.

[0057] In this embodiment, the number of rollers 400 is set to 3. For example, the 3 rollers 400 are spaced apart on the rear side of the 4 polishing wheels 300, so that the first sanding belt 200 forms 4 outwardly convex "V" shaped first sanding belts 200, and the 4 outwardly convex "V" shaped first sanding belts 200 are on the same horizontal line, which can realize the synchronous processing of 4 stations, improve efficiency, and save equipment space.

[0058] Specifically, please refer to Figure 2 The main body 100 also includes: a machine body 110, a first drive source 120, an active roller 130, and a set of driven rollers 140. The first drive source 120 is disposed on the machine body 110, the active roller 130 is rotatably disposed on the machine body 110, and the first drive source 120 is drivenly connected to the active roller 130. The driven rollers 140 are located between the active roller 130 and the polishing wheel 300. One driven roller 140 is located on the left side of the machine body 110, and the other driven roller 140 is located on the right side of the machine body 110. The driven rollers 140 are used to cooperate with the active roller 130 to support the first sanding belt 200.

[0059] In this embodiment, the first drive source 120 can drive the active roller 130 to rotate, and the active roller 130 can drive the driven roller 140 to rotate, so as to realize the operation of the first sanding belt 200. There are two driven rollers 140, which can be understood as two driven rollers 140 forming a group. For example, the number of polishing wheels 300 is set to four. The first polishing wheel 300, the second polishing wheel 300, the third polishing wheel 300, and the fourth polishing wheel 300 are arranged in a straight line. The first sanding belt 200 is wound around the first polishing wheel 300 via a driven roller 140, and the first sanding belt 200 is wound around the second polishing wheel 300, the third polishing wheel 300, and the fourth polishing wheel 300 in sequence. The first sanding belt 200 is also wound around the other driven roller 140 via the fourth polishing wheel 300. The transmission is stable, so as to realize the stable operation of the first sanding belt 200 driven by the first drive source 120.

[0060] Please see Figure 2The main body 100 also includes a sanding belt tensioning mechanism 150, which is disposed between two driven rollers 140. One driven roller 140 is fixed to the machine body 110, and the other driven roller 140 is movably connected to the sanding belt tensioning mechanism 150. The sanding belt tensioning mechanism 150 can drive the driven roller 140 to move, thereby tensioning the first sanding belt 200. For example, the sanding belt tensioning mechanism 150 can drive the right driven roller 140 to move away from the left driven roller 140, thereby tensioning the first sanding belt 200. Alternatively, the sanding belt tensioning mechanism 150 can drive the right driven roller 140 to move towards the left driven roller 140, thereby adjusting the tension of the first sanding belt 200. Preferably, the moving direction of the right driven roller 140 is parallel to the straight line direction of the four polishing wheels 300, ensuring stable transmission and enabling rapid adjustment of the tension of the first sanding belt 200.

[0061] For example, please see Figure 2 The driving roller 130, two driven rollers 140, and four polishing wheels 300 are arranged in a pentagonal pattern. A first abrasive belt 200 is wound around the driving roller 130 and the left driven roller 140 to form a first side. The first abrasive belt 200 is wound around the left driven roller 140 and the first polishing wheel 300 to form a second side. The first abrasive belt 200 is wound around the four polishing wheels 300 to form a wavy third side. The first abrasive belt 200 is wound around the fourth polishing wheel 300 and the right driven roller 140 to form a fourth side. A fifth edge is formed on the driven roller 140 and the driving roller 130 on the right side, thereby forming a closed-loop sanding belt. That is, the driving roller 130 can drive the first sanding belt 200 to rotate. The structure is simple and the operation is stable. The first edge and the fifth edge can be set approximately symmetrically from left to right, and the second edge and the fourth edge can be set approximately symmetrically from left to right. Since the driven roller 140 on the right side can move, it can adjust the tension of the first sanding belt 200. During the movement of the driven roller 140 on the right side, it may affect the position of the fourth edge and the fifth edge.

[0062] Specifically, please refer to Figure 2 The first drive source 120 includes a first motor 121 and a transmission mechanism 122. The first motor 121 is disposed on the machine body 110, and the transmission mechanism 122 is connected between the first motor 121 and the drive roller 130.

[0063] In this embodiment, the first motor 121 is used to drive the transmission mechanism 122 to operate, so that the transmission mechanism 122 drives the active roller 130 to rotate, thereby realizing the operation of the first sanding belt 200.

[0064] Specifically, please refer to Figure 2The transmission mechanism 122 includes a synchronous pulley assembly, which includes a driving pulley 123, a driven pulley 124, and a synchronous transmission belt. The driving pulley 123 is connected to the first motor 121 for transmission. The driven pulley 124 is rotatably mounted on the machine body 110 and is connected to the driving roller 130. The synchronous transmission belt is mounted on the driving pulley 123 and the driven pulley 124.

[0065] In this embodiment, the first motor 121 can drive the drive wheel 123 to rotate. The drive wheel 123 drives the driven wheel 124 to rotate via the synchronous transmission belt, thereby realizing the operation of the first sanding belt 200. The synchronous transmission belt has high transmission accuracy and good synchronization, which can enable the first motor 121 to accurately control the operation of the first sanding belt 200, so that the first sanding belt 200 has no slippage transmission, high efficiency and energy saving, compact structure, space saving, low noise and low vibration.

[0066] Specifically, please refer to Figure 1 The four-station belt sander also includes several liquid-cooled nozzles 500, which are located above the first sanding belt 200 and correspond one-to-one with the polishing wheel 300.

[0067] In this embodiment, a liquid-cooled nozzle 500 is provided above a polishing wheel 300, that is, a liquid-cooled nozzle 500 is provided above a grinding station. When grinding several workpieces simultaneously, the liquid-cooled nozzles 500 can cool and reduce the temperature of several grinding stations respectively to prevent thermal damage to the workpieces. The grinding fluid sprayed by the liquid-cooled nozzles 500 has a lubricating effect, reduces frictional resistance, improves the surface finish of the workpiece, reduces scratches, and reduces power consumption. At the same time, the liquid-cooled nozzles 500 can wash away debris and keep the workpiece clean during processing.

[0068] In summary, this application discloses a four-station belt sander, comprising: a main body, several parallel polishing wheels, and several rollers. The main body includes a first sanding belt, with the polishing wheels rotatably mounted on the main body and the rollers rotatably mounted on the main body. The first sanding belt is wound between the polishing wheels and the rollers, with the rollers and polishing wheels spaced apart, so that the first sanding belt forms multiple V-shaped grinding platforms arranged in a straight line. This application uses rollers in conjunction with polishing wheels to support the first sanding belt, enabling the first sanding belt to form multiple V-shaped grinding platforms arranged in a straight line. Each wave corresponds to one grinding station, allowing multiple grinding stations to process simultaneously, resulting in high processing efficiency and full utilization of the base equipment space.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
