Description

Technical Field

[0001] The utility model relates to the technical field of drum grinding and polishing machines, in particular to an inlet and outlet blocking structure of a polishing machine. Background Art

[0002] Polishing is a process that uses mechanical, chemical, or electrochemical action to reduce the surface roughness of a workpiece to achieve a bright, smooth surface. It is a finishing process performed using polishing tools, abrasive particles, or other polishing media. Polishing does not improve the dimensional or geometric accuracy of a workpiece, but rather aims to achieve a smooth or mirror-like finish. During rough polishing, a large number of steel balls, lime, and abrasives are placed in an inclined, can-shaped drum. As the drum rotates, the steel balls and abrasives randomly roll and collide within the drum, removing surface protrusions and reducing surface roughness.

[0003] After searching, the patent with announcement number CN218341774U discloses a suspended drum grinding and polishing machine, which includes a first vertical plate, a second vertical plate, a base, a drum, a box, a reciprocating grinding mechanism and an elastic mechanism. Through slots are opened on both sides of the base, and the bottom ends of the first and second vertical plates are connected to the corresponding through slots. A material receiving box is embedded in the middle position of the base. The drum is arranged between the first and second vertical plates. One side of the top of the drum is connected to the inlet and outlet. The top of the inlet and outlet is connected to the pipe mouth cover by threading. The box is welded to one side of the first vertical plate. The reciprocating grinding mechanism is arranged between the box and the drum, and the elastic mechanism is arranged in the base. Beneficial effect: Through the reciprocating grinding mechanism, reciprocating grinding and polishing are carried out, which improves the effect and efficiency of grinding and polishing.

[0004] The technical solution has the following problems:

[0005] Although the polishing objects can be loaded and unloaded through the inlet and outlet, the inlet and outlet are located at one end of the drum. When the polishing objects need to be poured out, the roller needs to be rotated back and forth to move the objects in the drum to the inlet and outlet position before the polishing objects can be poured out from the inlet and outlet, which is more troublesome and inefficient. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that although the polishing object can be loaded and unloaded through the inlet and outlet, the inlet and outlet are located at one end of the drum. When pouring out the polishing object, it is necessary to rotate the roller back and forth to move the object in the drum to the inlet and outlet position before the polishing object can be poured out from the inlet and outlet, which is more troublesome and inefficient. A polishing machine inlet and outlet blocking structure is proposed.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A polishing machine inlet and outlet blocking structure includes a frame and a roller for grinding and polishing objects, a collection box for collecting polished objects is placed on the bottom inner wall of the frame, two ends of the roller are rotatably connected to the inner walls of the frame on both sides, a motor for driving the roller to rotate is fixedly provided on one side of the frame, the output end of the motor passes through one side of the frame and is fixedly connected to one end of the roller, a large material opening for feeding and discharging materials is opened on the top of the roller, and a cover body for sealing the large material opening is provided on the large material opening, and the cover body is T-shaped;

The rotation of the twist bar drives the rotation of the first threaded rod, and the rotation of the first threaded rod drives the movement of the pressure plate, so that the pressure plate is close to the top of the cover body, and the cover body is pressed down and close to the roller, so that the cover body can be fixed, and then the collection box is placed on the bottom inner wall of the frame, so that one side of the collection box is in contact with the limit plate, and the knob is turned. The rotation of the knob drives the rotation of the second threaded rod. The rotation of the second threaded rod drives the movement of the abutment plate, so that the abutment plate moves to one side of the collection box, thereby limiting the collection box to prevent the collection box from moving, and then starting the motor. The rotation of the motor output end drives the rotation of the roller to grind and polish the object. After completion, the cover body is rotated upwards, the twist bar is rotated to release the pressure plate from fixing the cover body, the cover body is removed, and the roller is rotated. The object in the roller can be poured out through the large material port. The polished object can be directly poured out through the large material port, and there is no need to rotate the roller back and forth. It is more convenient and improves efficiency. Of course, it is also easy to take out from the large material port.

The two twist bars are rotated in sequence, and the rotation of the twist bars drives the rotation of the first threaded rod, and the rotation of the first threaded rod drives the movement of the pressure plate, so that the pressure plate is closely attached to the top of the cover, and the cover is pressed downward and closely attached to the roller, thereby fixing the cover.

[0020] In the utility model, the inlet and outlet blocking structure of the polishing machine is configured such that the collection box is placed on the bottom inner wall of the frame through a limiting mechanism, so that one side of the collection box is in contact with the limiting plate. When the knob is turned, the rotation of the knob drives the rotation of the second threaded rod, and the rotation of the second threaded rod drives the movement of the stop plate, so that the stop plate moves to one side of the collection box, thereby limiting the collection box and preventing the collection box from moving.

[0021] In the utility model, the polishing objects can be directly poured out through the large material opening, and there is no need to rotate the drum back and forth, which is more convenient and improves efficiency. The cover can be fixed by the fixing mechanism, and the collection box can be limited by the limiting mechanism to prevent the collection box from moving. BRIEF DESCRIPTION OF THE DRAWINGS
