Description

Technical Field

[0001] The utility model relates to the technical field of roller polishing devices, in particular to a roller polishing device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a finishing process that uses a polishing tool and abrasive particles or other polishing media to modify the surface of the workpiece. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss. Usually, a polishing wheel is used as the polishing tool. The polishing wheel is generally made of multiple layers of canvas, felt or leather laminated together and clamped by metal round plates on both sides. The rim of the wheel is coated with a polishing agent evenly mixed by fine abrasive powder and grease, etc.

[0003] The device for polishing a roller generally uses a grinding machine. The commonly used grinding machine generally consists of a motor and a polishing wheel. Such a grinding wheel generally has a length shorter than that of the roller. Therefore, the grinding machine needs not only to rotate around the roller for grinding, but also to move horizontally along the axis of the roller to replace the surface of the grinding roller, so as to achieve the effect of grinding and polishing the entire roller. In this way, the efficiency of grinding and polishing is reduced. Therefore, a roller polishing device is needed to achieve a polishing device that can cover the entire axis of the roller, so that the grinding device only needs to rotate and polish along the surface of the roller without moving horizontally along the axis of the roller to replace the surface of the grinding cylinder. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a roller polishing device that can cover the entire axis of the roller for polishing, thereby improving the polishing efficiency.

[0005] The technical solution to achieve the above purpose is: a roller polishing device, including a bottom plate. A chute is opened at the top end of the bottom plate. A guide rod is connected in the chute. Two support plates are connected to the upper end of the bottom plate. The side wall of the chute and the side wall of the guide rod are both slidably connected to the bottom end of one of the support plates. The other support plate is fixedly connected to the bottom plate. A through hole is opened on the side wall of the support plate. One of the support plates is rotatably connected with an adjusting rod. The side wall of the adjusting rod is threadedly connected to the side wall of the other support plate. A limiting mechanism is installed on the side wall of the support plate. A driving mechanism is arranged on the side wall of the other support plate. A polishing mechanism is installed on the support plate.

[0006] Preferably, the side wall of the bottom plate is connected with a housing. A revolving door is arranged on the side wall of the housing. The housing is made of transparent glass.

[0007] Preferably, the limiting mechanism includes a circular ring, a limiting rod and a limiting plate. A circular ring is connected to the side wall of the support plate. Three limiting rods distributed in an array are threadedly connected to the side wall of the circular ring. One end of the limiting rod is connected to the limiting plate.

[0008] Preferably, the through hole is located inside the circular ring, and the centers of the circular ring and the through hole are on the same straight line.

[0009] Preferably, the driving mechanism includes a motor and a driving gear. A motor is connected to the side wall of the other support plate, and the output end of the motor is connected to the driving gear.

[0010] Preferably, the polishing mechanism includes an external tooth ring, an outer ring, a rotating groove, a connecting rod, a threaded hole, a first screw rod, a placing plate, a polishing sandpaper, a pressing plate, a second screw rod and a connecting plate. Rotating grooves are formed in the side walls of the support plates. An external tooth ring is rotatably connected to the side wall of the rotating groove. An outer ring is connected to the side wall of the external tooth ring. Two symmetrically distributed connecting rods are commonly connected to the side walls of the two outer rings. A connecting plate is commonly connected to the side walls of the two outer rings. A threaded hole is formed in the side wall of the outer ring. A first screw rod is threadedly connected to the threaded hole. One end of the first screw rod is rotatably connected to the placing plate. The polishing sandpaper is placed on the side wall of the placing plate. A plurality of second screw rods are threadedly connected to the side wall of the connecting plate. One end of the second screw rod is rotatably connected to the pressing plate. The side wall of the external tooth ring meshes with the driving gear.

[0011] Preferably, the pressing plate is located between the connecting plate and the placing plate.

[0012] Preferably, the shape of the placing plate is arc-shaped.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1) Insert the rotating shaft on the roller body into the through hole, so that the roller body is located between the two support plates. Rotate the adjusting rod, and the adjusting rod drives one of the support plates to move, so that the distance between the two support plates is the same as the length of the roller body, thereby adapting to the length of the roller body. Use the limiting mechanism to clamp the rotating shaft of the roller body, thereby fixing the roller body. Start the driving mechanism, so that the polishing mechanism can cover the entire roller body axis and can be polished simultaneously, thereby improving the polishing efficiency.

[0015] 2) Stick the polishing sandpaper with the same length as the roller body tightly on the placing plate, and turn the two side walls at both ends of the polishing sandpaper to the back of the placing plate. At this time, rotate the second screw rod to make the pressing plate squeeze the part of the polishing sandpaper that has been turned to the back of the placing plate, so that the polishing sandpaper is fixed on the placing plate. Then, rotate the first screw rod to make the placing plate stick to the surface of the roller body, so that the polishing sandpaper is stuck and squeezed with the roller body. The driving gear drives the external tooth ring to rotate, the external tooth ring drives the outer ring to rotate, the outer ring drives the connecting plate to rotate, and the outer ring drives the placing plate to rotate through the first screw rod, so as to drive the polishing sandpaper to cover the entire axis of the roller body, so that the surface of the entire axis length of the roller body can be polished at the same time. Only by rotating the polishing sandpaper can the surface of the roller body be quickly polished, improving the efficiency of polishing the roller body. BRIEF DESCRIPTION OF THE DRAWINGS
