Description

Technical Field

[0001] The invention belongs to the technical field of automobile tire manufacturing, and in particular relates to an automatic tire scraping device. Background Art

[0002] The hair on the sidewall of a car tire will affect the appearance of the tire, making it less beautiful and of lower grade. The hair on the tread will cause irregular bumps on the tire surface, increasing the friction between the tire and the ground, thereby increasing the resistance of the vehicle when driving and increasing the energy consumption of the vehicle. In addition, when the car is driving at high speed, the friction between the tread hair and the ground will produce noise, reducing the quality of the car. The existing all-steel tire scraping machine is a manual scraping machine, mainly a manual tire scraping machine and an automatic tire scraping machine. The principle is that two tires are put into the tires manually or by machine, and the rollers rotate in the same direction to drive the tires to rotate, and the scraping operation is performed manually with a hand-held scraper. After completing the scraping operation of the tread and sidewall, the tire is removed manually or by machine. The disadvantages are as follows:

[0003] 1. It requires manual hand-held shaving, which has many operation steps, high labor intensity and high labor cost;

[0004] 2. The scraping quality is poor, the length of the tire hair is different, and it is easy to scratch the tire, resulting in poor tire appearance quality, and even producing waste tires, which greatly increases the production cost;

[0005] 3. The tire rotates very fast, and there is a risk of the tire being thrown out and injuring someone;

[0006] 4. During the scraping operation, the tire rotates at a high speed and throws the tire hair out, which splashes everywhere. The working environment is poor, the hygiene around the machine is relatively poor, and it is difficult to clean.

[0007] Based on the above problems with manual hair removal, it is increasingly urgent to find an automated trimming machine to replace manual trimming, which can improve product quality on the one hand and work efficiency and work environment on the other. Summary of the invention

[0008] Based on the above problems, the present invention discloses an automatic tire scraping device, including a tread scraper assembly and a sidewall scraper assembly that can move automatically. Under the drive of a driving motor 231, the movement of the automatic scraping device is controlled by a compiled program, so that the sidewall scraper assembly and the tread scraper assembly move along the tire contour, and the tire rotates at a high speed, so as to achieve the purpose of shaving the tire hair. The technical solution of the present invention is as follows:

[0009] A tire automatic scraping device, from the time the tire enters the scraping device to the time the tire is output from the device, the scraping device sequentially includes a tire input mechanism, a scraping mechanism and a tire output mechanism, characterized in that the scraping mechanism includes: a tread scraper assembly, including at least two groups of tread scrapers, the tread scrapers are sequentially arranged along the tread arc of the tire to be scraped, and the tread scrapers are in contact with the tread; a sidewall scraper assembly, including at least two groups of sidewall scrapers, the sidewall scrapers are symmetrically arranged on both sides of the tire to be scraped, and are in contact with the sidewalls to scrape off the tire hair on the sidewalls; a driving roller, arranged at the bottom of the vertically placed tire to be scraped, and a motor drives the driving roller to rotate at high speed, thereby driving the rotation of the tire to be scraped;

[0010] The shaving mechanism also includes a fetal hair collecting device, which includes a vacuum suction tube and a fetal hair collecting box. The vacuum suction tube is fixed on the outside of the shaver, the inlet of the vacuum suction tube sucks the scraped fetal hair, and the outlet is connected to the fetal hair collecting box.

[0011] Furthermore, the scraping mechanism also includes a tread scraper driving mechanism for driving the tread scraper assembly to move toward both sides from the middle in the tread width direction.

[0012] Furthermore, the scraping mechanism also includes a sidewall scraper driving mechanism for driving the sidewall scraper assembly to move upward along the sidewall from the inner diameter of the tire.

[0013] Furthermore, the tire input mechanism includes an input belt conveyor 11 and an input station frame, the inlet of the input belt conveyor 11 is used to input the tire to be scraped, the outlet is connected to the input station frame, and the outlet of the input station frame is connected to the inlet of the scraping mechanism.

[0014] Furthermore, the inlet of the tire output mechanism is connected to the outlet of the scraping mechanism, so as to output the scraped tire out of the automatic scraping device.

[0015] The beneficial effects of the present invention are:

[0016] 1. The tread scraper assembly of the present invention comprises at least two sets of tread scrapers, which move from the middle of the tread width direction to both sides, and can completely remove the hair on the tread.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0025] refer to Figure 1-3The present invention discloses an automatic tire scraping device. The tire to be scraped first enters the input belt conveyor 11. The input belt conveyor 11 is a slope with a certain angle. The lower end of the input belt conveyor 11 serves as the entrance of the tire to be scraped. The entrance can be directly connected to the tire conveyor line. The other end is connected to the input station frame 12. The input station frame 12 is a deep frame with fences on three sides and a rectangular cross section. The width of the deep frame is slightly larger than the width of the tire. The height of the deep frame is larger than two-thirds of the height of the wheel sleeve after being placed vertically. The scraped tire can be placed vertically in the deep frame and will not fall. The side of the deep frame without fences is connected to the entrance of the scraping mechanism 2, and the tire enters the scraping mechanism 2 from the deep frame. When in use, the tire is placed flat on the input belt conveyor 11. As the input belt conveyor 11 moves, the tire is transferred to the top of the input belt conveyor 11. The top of the input belt conveyor 11 is connected to the input station frame 12 through a curved smooth slope. The tire slides into the input station frame 12 through the slope, and the tire changes from a flat state to a vertical state.

[0026] The tire enters the scraping mechanism 2 from a vertical state, and the tread scraper assembly 21 completes the removal of the tire hair on the tread. The tread scraper assembly 21 includes at least two groups of tread scrapers 211, the tread scrapers 211 are located at the top of the vertically placed tire, the ends of the tread scrapers 211 are in contact with the tread, and a group of tread scrapers are distributed and placed on both sides along the curvature direction of the tire with the highest point of the tire as the center, and the tread scrapers 211 are placed in the middle position in the width direction of the tire tread. The tread scraper assembly 21 also includes a tread scraper driving mechanism 212. Under the drive of the tread scraper driving mechanism 212, the two groups of tread scrapers move from the middle of the tread to both sides respectively, one group of tread scrapers moves horizontally from the middle of the tread to the outside of the tire, and the other group of tread scrapers moves horizontally from the middle of the tread to the inside of the tire. The tread scraper driving mechanism 212 drives the left and right screws to rotate through the reducer, the synchronous pulley rotates, and the left and right screws on the other side rotate through the connecting rod, driving the parallel movement of the tread scrapers connected to the two left and right screws. When the two sets of tread scrapers 211 move from the middle of the tread to the shoulders on both sides, the tread hair is removed.

[0027] Furthermore, the scraping mechanism 2 of the present embodiment further comprises at least two sets of sidewall scraper assemblies 22, the sidewall scraper assemblies 22 comprising a plurality of sidewall scrapers 221 and the plurality of sidewall scrapers 221 are symmetrically arranged on both sides of the tire to be scraped, and the ends of the sidewall scrapers 221 are in contact with the sidewalls. The sidewall scraper driving mechanism 222 drives the movement of the sidewall scrapers 221, the sidewall scrapers 221 are initially located at the inner sub-mouth of the tire sidewall, and move upward from the inner side of the sidewall to the tire shoulder to complete the removal of the sidewall hair.

[0028] The pressure adjustment of the contact force between the scraper and the tire is achieved by controlling a small cylinder with a proportional valve, which ensures full contact without excessive contact pressure. When the pressure is too high, the scraper may scratch the tire surface, and the end of the scraper moves slightly away from the tread to reduce the pressure.

[0029] Furthermore, the scraping mechanism of this embodiment also includes a driving roller 23, which is arranged at the bottom of the vertically placed tire to be scraped. The driving motor 231 drives the roller to rotate at high speed, thereby driving the rotation of the tire to be scraped. There are preferably two driving rollers, which rotate in the same direction.

[0030] Furthermore, the shaving mechanism of this embodiment also includes a fetal hair collecting device 24, which includes a vacuum tube 241 and a fetal hair collecting box 242. The vacuum tube is fixed on the outside of the shaver, and the inlet of the vacuum tube sucks in the shaved fetal hair. The vacuum tube has a certain length, and the outlet is connected to the fetal hair collecting box. The fetal hair collecting box is placed outside the shaving mechanism to clean the collected fetal hair regularly.

[0031] Furthermore, the scraping mechanism 2 also includes a limiting roller assembly 25, which is composed of at least two groups of rollers. The rollers are symmetrically arranged on both sides of the hub of the vertically placed tire to be scraped. Preferably, the rollers are arranged at the center of the hub to fix the tire when the tire rotates at high speed. The limiting roller assembly 25 includes a support frame 251 and a limiting shaft 252. The support frame is fixedly arranged on the bracket of the scraping mechanism. One end of the limiting shaft is connected to the support frame, and the other end is a fixed end 253, which contacts the center of the hub of the tire. The limiting shaft 252 is parallel to the ground, and the fixed end 253 is connected to the main body of the limiting shaft through a rotating shaft. When the tire rotates at high speed, the main body of the limiting shaft 252 remains stationary, and the fixed end 253 and the tire keep rotating at high speed.

[0032] Furthermore, a tire kicking mechanism 26 is provided at the bottom of the scraping mechanism, and the tire kicking mechanism includes a kicking belt and a roller. When the tire is cleaned of hair, the kicking belt rises and contacts with the bottom of the tire, and the roller is driven to swing by the cylinder to transfer the tire to the tire output mechanism.

[0033] The working process of the tire automatic scraping device of this embodiment is as follows: the tire to be scraped is placed flat on the surface of the input belt conveyor 11. As the input belt conveyor 11 moves, the tire is moved to the top and slides into the input station frame 12, and the tire changes from a horizontal state to a vertical state. The tire moves from the input station frame 12 into the scraping mechanism, and the two driving rollers 23 rotate in the same direction under the drive of the driving motor 231, driving the tire to rotate at high speed. The tread scraper assembly, driven by the tread scraper driver, contacts the tire tread and separates left and right. Relying on the speed difference between the high-speed rotation of the tire and the scraper, the tire hair is inserted into the blade, so that the tire hair and the tire body are separated. At the same time, the side scraper assembly, driven by the side scraper driver, contacts the side of the tire and moves from bottom to top along the side profile to shave the side hair of the tire. Since the tire is moving at high speed, the tread scraper and the sidewall scraper move slowly. When the horizontal moving distance of the scraper is less than the length of the scraper in contact with the tread, the tire rotates at high speed for more than one circle, so the scraper can completely contact all areas of the tread and sidewall of the tire. That is, when the tread scraper moves from the middle to the two sides, the hair removal of the entire tire tread can be completed. When the sidewall scraper moves from the bottom to the shoulder, the hair removal of the entire tire sidewall can be completed. The tread scraper assembly moves to the shoulder, and the tread scraper assembly is lifted and returned to its position. The sidewall scraper assembly moves to the shoulder, and the hair removal is completed. The driving roller decelerates until it stops rotating, and the tire removal mechanism starts working. The tire is sent to the output station frame, and a cycle ends. Restart the hair removal work of the next tire to ensure that the tire scraping cycle time is completed in a short time. In addition, a hair collection device is set to prevent hair splashing, because the absorption tube of the hair collection device is a vacuum suction tube. The scraped fetal hair can be sucked into the fetal hair collection box in time, and the fetal hair in the collection box can be cleaned regularly.
