Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt sander technology, and more specifically, to a multi-station belt sander design. Background Technology
[0002] A belt sander is a device that uses a sanding belt for grinding. It is mainly used for rust removal and polishing in industries such as hardware manufacturing, vehicle parts, steel and wood furniture, instrumentation machinery, standard parts, and before and after electroplating. It is the best choice for polishing round rods and slender shafts. In actual use, it has the advantages of simple operation, stable structure, and good performance.
[0003] Existing belt sanders typically have only one station, meaning they can only clamp and grind one workpiece at a time. Grinding multiple workpieces requires sequential processing, necessitating frequent operation of the clamping structure, which reduces the practicality of existing belt sanders. Furthermore, the grinding process generates flying debris, and the lack of protective structures means that contact with the operator can cause discomfort. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-station belt sander with multiple stations, enabling simultaneous clamping and grinding of multiple workpieces. It also features a protective structure to prevent sputtering debris from contacting the operator during grinding, thus solving the problems mentioned in the background.
[0006] (II) Technical Solution
[0007] To achieve the advantages of having multiple workstations, simultaneously clamping and grinding multiple workpieces, and having a protective structure to prevent sputtering debris from contacting the operator during grinding, the specific technical solution adopted by this utility model is as follows: A multi-station belt sander includes a base, a frame mounted on the upper part of the base, and two sets of conveyor rollers mounted inside the frame via bearings. Sanding belts are sleeved on the sidewalls of the two sets of conveyor rollers. A drive motor is mounted on the upper part of the frame, and the output end of the drive motor is connected to one set of conveyor rollers via a coupling. The base has multiple through slots on its end face, and multiple mounting shafts are installed inside each through slot via bearings. Limiting wheels are fixedly sleeved on the side walls of each mounting shaft. A movable plate slides through the multiple limiting wheels on the same side.

Clamping plates are fixedly installed at the opposing ends of the two sets of mounting screws on the same side. Two sets of mounting nuts are sleeved on the side walls of the two sets of mounting screws on the same side.
[0008] Furthermore, a connecting shaft is passed through the end face of the transparent plate group on the same side via a bearing, and two sets of iron plates are bonded to the side wall of the connecting shaft group on the same side. Sponge boards are bonded to the facing surfaces of the two sets of iron plates on the same side, and two sets of magnet blocks are bonded to the side of the transparent plate group on the same side away from the frame.
[0009] Furthermore, a handwheel is installed at the end of the connecting shaft on the same side away from the frame.
[0010] Furthermore, four sets of support legs are installed on the lower part of the base.
[0011] Furthermore, an electrical control box is installed on one side of the base, and a control panel and a storage battery are installed inside the electrical control box. The control panel is electrically connected to the storage battery and the drive motor via wires.
[0012] Furthermore, the two sets of mounting screws on the same side and the four sets of mounting nuts on the same side are threadedly engaged with each other.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a multi-station belt sander with the following advantages:
[0015] (1) This utility model is equipped with a movable plate. When using a multi-station belt sander, a workpiece can be moved to the two sets of clamping plates on the same side. Then, the two sets of clamping plates on the same side can be moved towards each other. When these two sets of clamping plates are in close contact with the workpiece, the two sets of mounting screws and the four sets of mounting nuts on the same side are threaded together. The operator can rotate the four sets of mounting nuts on the same side clockwise and counterclockwise by hand. When the four sets of mounting nuts on the same side are in close contact with the concave seat on the same side, the workpiece is stably clamped. The clamping of other workpieces can be achieved in the same way. Then, the control panel is used to make the drive motor work. The output end of the drive motor can drive A set of conveyor rollers rotates, which drives the sanding belt to rotate and move. At this time, with the help of multiple sets of mounting shafts and multiple sets of limit wheels on the same side, one operator can move a set of moving plates backward by hand. When the workpiece contacts the rotating sanding belt, grinding can be performed. When another operator moves this set of moving plates forward, it can drive a set of workpieces behind it to be ground. At this time, a set of workpieces can be disassembled and replaced. The use of the other sets of moving plates is the same as the operation. As can be seen from the operation, the set of moving plates has multiple stations and can clamp and grind multiple workpieces at the same time, which improves the practicality of the multi-station design sander.
[0016] (2) This utility model is equipped with transparent plates. As can be seen from the above operation, multiple sets of moving plates can be used to grind multiple workpieces. The generated debris will be intercepted by multiple sets of transparent plates, which can prevent the splashed debris from contacting the operator. When debris is adsorbed on a set of transparent plates, the operator can rotate a set of handwheels on the same side. This set of handwheels can rotate two sets of iron plates and two sets of sponge plates on the same side through a set of connecting shafts on the same side. The rotating two sets of sponge plates can wipe away the debris adhering to the surface of the set of transparent plates on the same side. The two sets of magnets on the same side can attract the set of iron plates on the same side, ensuring the stability of the two sets of sponge plates on the same side. The use of the other sets of transparent plates is the same as the operation. As can be seen from the operation, the transparent plates have a protective structure, which can prevent the splashed debris during the grinding process from contacting the operator, thus providing protection for users of multi-station belt sanders.

The sidewalls of the multiple mounting shafts 9 are fixedly sleeved. The belt sander has a limit wheel 10, and multiple sets of limit wheels 10 on the same side slide through a movable plate 6. The upper parts of both ends of the multiple sets of movable plates 6 are fixedly connected to concave seats 12 and transparent plates 7. The two sides of the multiple sets of concave seats 12 are slidably connected to mounting screws 13. The opposing ends of the two sets of mounting screws 13 on the same side are fixedly installed with clamping plates 14. The side walls of the two sets of mounting screws 13 on the same side are fitted with two sets of mounting nuts 15. Through the movable plate 6, multiple workstations are provided, which can clamp and grind multiple workpieces at the same time, thus improving the practicality of the multi-station belt sander.
[0028] In one embodiment, a connecting shaft 16 is passed through the end face of a set of transparent plates 7 on the same side via a bearing. Two sets of iron plates 17 are bonded to the side wall of the set of connecting shafts 16 on the same side.

[0029] In one embodiment, a handwheel 19 is installed at the end of a set of connecting shafts 16 on the same side away from the frame 2.
[0030] In one embodiment, four sets of support legs are installed on the lower part of the base 1.
[0031] In one embodiment, an electrical control box is installed on one side of the base 1, and a control panel and a storage battery are installed inside the electrical control box.

[0033] Working principle:
[0034] In actual use of a multi-station belt sander, a workpiece can be moved to one of the two sets of clamping plates 14 on the same side. Then, the two sets of clamping plates 14 can be moved towards each other. When these two sets of clamping plates 14 are in close contact with the workpiece, the two sets of mounting screws 13 and the four sets of mounting nuts 15 on the same side engage with each other. The operator manually rotates the four sets of mounting nuts 15 clockwise and counterclockwise. When the four sets of mounting nuts 15 are in close contact with the concave seat 12 on the same side, the workpiece is stably clamped. The clamping of other workpieces can be achieved through the same operation. Using the control panel, the drive motor 5 is activated. The output of the drive motor 5 drives a set of conveyor rollers 3 to rotate, which in turn pushes the sanding belt 4 to rotate and move. With the help of multiple mounting shafts 9 and multiple limit wheels 10 on the same side, one operator can manually move a set of moving plates 6 backward. When the workpiece contacts the rotating sanding belt 4, grinding can begin. When another operator moves this set of moving plates 6 forward, it can drive a set of workpieces behind it to be ground. At this time, a pre-selected set of workpieces can be disassembled and replaced. The use of the remaining sets of moving plates 6 is similar. Thus, the set of moving plates 6 provides multiple workstations, allowing for simultaneous clamping and grinding of multiple workpieces, improving the practicality of the multi-station sander design. Furthermore, as shown in the above operation, moving multiple sets of moving plates 6 allows for grinding of multiple workpieces. The generated debris is intercepted by multiple sets of transparent plates 7, preventing splashed debris from contacting the operator. When debris adheres to a set of transparent plates 7, the operator can manually rotate a set of handwheels 19 on the same side. This set of handwheels 19 can... A set of connecting shafts 16 on the same side causes two sets of iron plates 17 and two sets of sponge plates 18 on the same side to rotate. The rotating sponge plates 18 can wipe away the debris adhering to the surface of a set of transparent plates 7 on the same side. Two sets of magnets 11 on the same side can attract a set of iron plates 17 on the same side, ensuring the stability of the two sets of sponge plates 18 on the same side. The use of the other sets of transparent plates 7 is the same as the operation. Through the setting of the transparent plates 7, a protective structure is provided, which can prevent the splashing debris during the grinding process from contacting the operator, thus providing protection for users of multi-station belt sanders.
