Description

Technical Field

[0001] This utility model relates to the field of screw manufacturing technology, and in particular to a screw polishing roller. Background Technology

[0002] As the most common standard component in mechanical connections, the surface quality of screws directly affects connection strength, corrosion resistance, and assembly accuracy. In modern manufacturing, with the widespread adoption of automated assembly technology, the requirements for the surface finish and consistency of screws are becoming increasingly stringent.

[0003] In existing technologies, screw polishing rollers typically involve pouring both screws and abrasive particles into the roller. As the roller rotates, the abrasive particles rub against the screws, removing burrs. However, during unloading, workers must separate the screws from the abrasive particles using a sieve frame, and the abrasive particles must be poured back into the roller. This significantly increases the workflow and reduces efficiency. Therefore, a screw polishing roller was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screw polishing roller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screw polishing roller includes a base, with support plates fixedly connected to both ends of the top of the base. Connectors are fixedly connected to the bottom of the two support plates on their adjacent sides. A common collection box is fixedly connected between the two connectors. An inclined guide trough is provided at the bottom center of the collection box. A conveying cylinder is fixedly connected to the middle of one side of the collection box via a connecting pipe, and the conveying cylinder is adapted to the bottom of the inclined guide trough. A motor is fixedly connected to the top outer wall of the conveying cylinder, and a rotating rod is fixedly connected to the bottom output end of the motor through the conveying cylinder. The bottom of the rotating rod is rotatably connected to the bottom of the inner wall of the conveying cylinder. An auger is fixedly connected to the circumferential surface of the rotating rod. Abrasive particles are collected through the inclined guide trough, and the abrasive particles return to the interior of the hexagonal roller via the auger and the conveying cylinder.

[0007] Preferably, a fixing member is fixedly connected to the outer wall of the conveying cylinder, and the fixing member is fixedly connected to the outer wall of the collection box. A discharge pipe is fixedly connected to the top of the conveying cylinder near the middle of the base.

[0008] Preferably, a connecting plate is fixedly connected to one side of the middle of the two support plates that are close to each other, and the same U-shaped frame is fixedly connected between the two connecting plates. Sliding grooves are provided on both sides of the inner wall of the U-shaped frame, and the same screen frame is slidably connected between the two sliding grooves. The screen frame facilitates the separation of screws and abrasive particles, thereby improving the separation efficiency between the two.

[0009] Preferably, a rotating rod is rotatably connected to the top of each of the two support plates on their adjacent sides, and a hexagonal roller is fixedly connected between the two rotating rods. The top of the hexagonal roller is provided with a feed inlet, and a baffle is rotatably connected to the top of the feed inlet. A locking buckle is provided between the baffle and the hexagonal roller.

[0010] Preferably, a geared motor is fixedly connected to the top outer side of one of the support plates, and a small gear is fixedly connected to the output end of the geared motor through the support plate.

[0011] Preferably, a large gear is fixedly sleeved on the rotating rod near the small gear, and the large gear meshes with the small gear.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing technologies such as a collection box, inclined guide chute, conveying cylinder, auger, motor, and screen frame, when unloading is required, the screws and grinding particles in the hexagonal drum are poured into the screen frame. The shaking of the screen frame separates the screws from the grinding particles. Simultaneously, the rotation of the auger lifts the grinding particles in the inclined guide chute from the conveying cylinder to the unloading pipe, and then back into the hexagonal drum. This effectively solves the problem of low work efficiency mentioned in the background technology, thus achieving easy separation of screws and grinding particles. The auger and conveying system realize the automatic recovery and recycling of grinding particles, improving work efficiency and reducing the labor intensity of manual operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A screw polishing roller includes a base 1, with support plates 2 fixedly connected to both ends of the top of the base 1. Connecting parts 3 are fixedly connected to the bottom of the two support plates 2 on their adjacent sides. A collection box 301 is fixedly connected between the two connecting parts 3. An inclined guide trough 302 is provided at the middle of the bottom of the collection box 301. A conveying cylinder 303 is fixedly connected to the middle of the outer side of the collection box 301 through a connecting pipe. The conveying cylinder 303 is adapted to the bottom of the inclined guide trough 302. A motor 307 is fixedly connected to the outer wall of the top of the conveying cylinder 303. A rotating rod 305 is fixedly connected to the bottom of the conveying cylinder 303 through the bottom output end of the motor 307. The bottom of the rotating rod 305 is rotatably connected to the bottom of the inner wall of the conveying cylinder 303. An auger 306 is fixedly connected to the circumferential surface of the rotating rod 305. Through the arrangement of the collection box 301, the inclined guide trough 302, and the conveying cylinder 303, grinding particles can be collected and conveyed to the hexagonal roller 4, reducing manual labor intensity and improving work efficiency.

[0021] In this utility model, a fixing member 304 is fixedly connected to the outer wall of the conveying cylinder 303, and the fixing member 304 is fixedly connected to the outer wall of the collecting box 301. A discharge pipe 308 is fixedly connected to the top of the conveying cylinder 303 near the middle of the base 1. The bottom of the discharge pipe 308 is close to the baffle 402, which can directly convey the grinding particles into the hexagonal roller 4.

[0022] In this utility model, a connecting plate 201 is fixedly connected to one side of the middle of the two support plates 2 that are close to each other. The same U-shaped frame 202 is fixedly connected between the two connecting plates 201. Sliding grooves 203 are provided on both sides of the inner wall of the U-shaped frame 202. The same sieve frame 204 is slidably connected between the two sliding grooves 203. The setting of the sieve frame 204 makes it easy to separate the screw from the grinding particles and to transfer and collect the screw.

[0023] In this utility model, rotating rods 401 are rotatably connected to the top of the two support plates 2 on their adjacent sides. The same hexagonal roller 4 is fixedly connected between the two rotating rods 401. A feed inlet is provided at the top of the hexagonal roller 4, and a baffle 402 is rotatably connected to the top of the feed inlet. A locking buckle is provided between the baffle 402 and the hexagonal roller 4.

[0024] In this utility model, a reduction motor 5 is fixedly connected to the outer top of one of the support plates 2, and a small gear 501 is fixedly connected to the output end of the reduction motor 5 through the support plate 2.

[0025] In this utility model, a large gear 403 is fixedly sleeved on the rotating rod 401 near the small gear 501, and the large gear 403 meshes with the small gear 501. Through the cooperation of the small gear 501 and the large gear 403, the reduction motor 5 can drive the hexagonal roller 4 to rotate.

[0026] Working principle: During operation, the device is controlled by the reduction motor 5, causing the baffle 402 of the hexagonal roller 4 to face upwards. Opening the latch of the baffle 402 allows the screws and abrasive particles to be polished to be poured into the hexagonal roller 4. Then, the reduction motor 5 is started, and through the combination of the pinion 501 and the gear 403, the hexagonal roller 4 rotates with the screws. The friction between the screws and the abrasive particles polishes the screws, removing burrs from the production process. After polishing, when unloading is required, the reduction motor 5 is turned off, and the baffle 402 is opened. The hexagonal roller 4 is then rotated so that one side of the baffle 402 faces downwards, causing the screws and abrasive particles to fall into the screen frame 204. A handle is provided on the outside of the screen frame 204. The handle drives the screen frame 204 to swing back and forth in the chute 203, causing the grinding particles in the screen frame 204 to fall into the collection box 301, while the screws remain in the screen frame 204. By pulling out the screen frame 204, the screws can be easily collected. At the same time, the grinding particles in the collection box 301 are gathered at the bottom of the conveying cylinder 303 under the action of the inclined guide chute 302. The motor 307 is started, which causes the rotating rod 305 to drive the auger 306 to rotate, so that the grinding particles at the bottom of the conveying cylinder 303 gradually rise and are discharged through the discharge pipe 308 and return to the hexagonal drum 4. When it is necessary to clean the grinding particles, the grinding particles at the discharge pipe 308 can be collected and cleaned through the collection frame.
