Description

Technical Field

[0001] This utility model relates to the technical field of through-type polishing machines, specifically a through-type polishing machine. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright, smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the workpiece surface. Polishing does not improve the dimensional or geometric accuracy of the workpiece; rather, it aims to achieve a smooth surface or mirror finish. Sometimes it is also used to eliminate gloss (matte finish). For barrelled workpieces, such as the surface of cans, a through-type belt polisher is commonly used. Existing through-type polishers consist of support rollers and a belt polishing assembly. The belt polishing assembly, composed of rollers and abrasive belts, is located above the support rollers. Multiple rollers pass through the belt... The belt drive connects the two cans, and a motor drives a roller to rotate, allowing the sanding belt to move at high speed. During polishing, the can is placed between two rows of support rollers, so that the high-speed moving sanding belt contacts the surface of the can. While the can rotates, the surface of the can is also polished. Traditional through-type polishing machines require manual feeding, which is labor-intensive and results in uneven feeding speed. For polishing cans of different sizes, the distance between the support rollers and the sanding belt cannot be adjusted according to the overall size of the can. Only the height of the sanding belt is adjusted, while the distance between the two support rollers remains unchanged. Therefore, it cannot polish very small cans, which is a major limitation. To address this, we propose a through-type polishing machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a through-type polishing machine with automatic feeding, uniform feeding speed, and reduced manual labor. It is also equipped with an overall adjustment device that can simultaneously adjust the distance between the support roller and the sanding belt, as well as the distance between the two support rollers. Through overall adjustment, the support roller and the sanding belt can always maintain an appropriate distance, which is convenient for polishing small tanks. This can effectively solve the problems in the background art.

The middle of the lower inner end of the two sliding frames 31 is threaded to the outer surface of the bidirectional lead screw 33, providing a basis for supporting the tank and adjusting the distance between the two support rollers 32. Polishing mechanism 3 also includes an adjustment component 34, which includes a sliding plate 341, a lead screw 342, a bevel gear 343, and a bevel gear.

The polishing mechanism 3 also includes a polishing assembly 35, which includes a frame 351, rollers 352, abrasive belts 353, and a second motor 354. The frame 351 is evenly arranged at the front end of the sliding plate 341. The rollers 352 are all rotatably connected inside the frame 351.

The polishing mechanism 3 also includes a second lead screw 36 and a slider 37. The polishing mechanism 3 includes an electric push rod 38 and a lead screw 36, which are rotatably connected to the upper middle of the mounting base 2. A slider 37 is slidably connected to the upper middle of the mounting base 2, with its inner middle threadedly connected to the outer surface of the lead screw 36.

The polishing mechanism 3 also includes a motor 39, which is located on the right middle of the mounting base 2. Its input end is electrically connected to the output end of the microcontroller 4, and the left end of its output shaft is fixedly connected to the right end of the lead screw 36, providing stable drive for automatic feeding. Automatic feeding is achieved with a uniform feeding speed, reducing manual labor. An overall adjustment device is also included.The spacing between the support roller 32 and the sanding belt 353, as well as the spacing between the two support rollers 32, can be adjusted simultaneously. This overall adjustment ensures that the support roller 32 and the sanding belt 353 maintain an appropriate spacing, facilitating the polishing of small cans.

[0023] The working principle of the through-type polishing machine provided by this utility model is as follows: During polishing, the tank rolls from the previous process to between two support rollers 32. The two support rollers 32 support the tank. At this time, the electric push rod 38 is in the initial position, which is the rightmost side of the mounting base 2. The microcontroller 4 controls the electric push rod 38 to work. The telescopic end of the electric push rod 38 extends upward until the telescopic end of the electric push rod 38 is located on the right side of the tank. At this time, the microcontroller 4 controls the motor 39 to run. The output shaft of the motor 39 drives the lead screw 36 to rotate clockwise. As the lead screw 36 rotates, the slider 37 moves to the left, driving the electric push rod 38 to move to the left synchronously. The telescopic end of the electric push rod 38 contacts the right end of the tank, pushing the tank to move to the left. Simultaneously, the microcontroller 4 controls the operation of motor 2 354, which drives the rear roller 352 to rotate. Through the transmission of the sanding belt 353, the three rollers 352 rotate synchronously, and the sanding belt 353 rotates at high speed along the direction of the three rollers 352. At this time, there is still a certain gap between the sanding belt 353 and the surface of the tank. When the tank moves to below the sanding belt 353 on the right side, the microcontroller 4 controls the operation of motor 1 345. The output shaft of motor 1 345 drives the lead screw 1 342 to rotate forward, and the sliding plate 341 moves down synchronously, driving the polishing assembly 35 to move down accordingly. At the same time, as the lead screw 1 342 rotates, the bevel gear 1 343 also rotates synchronously. Because bevel gear 1 343 is meshed with bevel gear 2 344, bevel gear 2 344... 4 also rotates synchronously, driving the bidirectional lead screw 33 to rotate accordingly. As the bidirectional lead screw 33 rotates, the two sliding frames 31 move inward synchronously, and the two support rollers 32 also move inward accordingly. At this time, the inward movement of the two support rollers 32 squeezes the can upward, the polishing assembly 35 moves downward, and the sanding belt 353 also moves downward. The sanding belt 353 contacts the surface of the can, and the high-speed rotating sanding belt 353 drives the can to rotate between the two support rollers 32 through friction. At the same time, the sanding belt 353 polishes the surface of the can. As the can moves to the left, the mesh size of the sanding belt 353 increases successively, and the surface of the can becomes smoother and smoother until the electric push rod 38 pushes the can to the next process. At this time, the microcontroller 4 controls the electric push rod 38 to retract the telescopic end, and then... The microcontroller 4 controls the motor 39 to reverse, bringing the electric push rod 38 back to its original position for the next polishing operation. When the diameter of the tank is too small, the microcontroller 4 controls the motor 1 345 to operate. The output shaft of the motor 1 345 drives the lead screw 1 342 to rotate forward, causing the sliding plate 341 and the polishing assembly 35 to move downward. At the same time, as the lead screw 1 342 rotates, the bevel gear 1 343 also rotates synchronously. Through the meshing bevel gear 2 344, it also rotates synchronously, driving the bidirectional lead screw 33 to rotate accordingly. The two sliding frames 31 move inward synchronously, and the two support rollers 32 also move inward accordingly. The distance between the two support rollers 32 becomes smaller, and the distance between the sanding belt 353 and the two support rollers 32 also becomes smaller synchronously, which facilitates the polishing of tanks with too small a size.

[0024] It is worth noting that the microcontroller 4 disclosed in the above embodiments is an STM8S003F3P6 microcontroller, motor 1 345 is a 60TM-01330F5-C motor, motor 2 354 is a 57BYGH601-05AG6 motor, electric actuator 38 is a YMD-601 electric actuator, and motor 39 is a VGF42 motor.
