[0002] Children's cars are a major category of children's toys, which include four major categories: children's bicycles, children's strollers, baby walkers, and children's tricycles. Children's car tires are made of molds. The exhaust holes on the tire vulcanization mold can discharge the gas generated when the tire is molded. After the tire is molded and cooled in the mold, some rubber remains in the exhaust holes of the mold. After the tire is taken out of the mold, the rubber in the exhaust holes forms "fetal hair" attached to the tire surface. The "fetal hair" of the new tire not only affects the appearance of the tire and affects sales, but the presence of the fetal hair will also increase the resistance during driving. Therefore, there is a process to remove the fetal hair when the new tire leaves the factory.

[0003] In the prior art, after the production of rubber tires for baby carriages is completed, they are usually scraped manually. This scraping method not only requires a lot of manpower and has low processing efficiency, but also makes it difficult to ensure the scraping quality of the tires. A large number of defective products are produced during the scraping process. Therefore, an automatic scraping device for rubber tires for baby carriages is urgently needed.

[0004] Therefore, there is a need for an automatic scraping device for the rubber tire of a baby carriage to solve the problems of high labor cost and low scraping efficiency of the baby carriage tire in the prior art. Utility Model Content

[0021] See also Figure 1-3 The utility model provides an automatic hair removal device for a rubber tire of a baby carriage, comprising a bottom plate 1, an automatic hair removal mechanism 2 is arranged inside the bottom plate 1, and a fixing mechanism 3 is arranged on the upper side of the bottom plate 1;

[0022] The automatic hair removal mechanism 2 includes an open groove 4, the inner side of the open groove 4 is used to scrape the hair of the baby carriage tire, and limiting holes 5 are arranged on the front and rear parts of the left and right walls on the inner side of the open groove 4. Connecting rods 6 are penetrated and slidably connected to the inner sides of the limiting holes 5. The limiting holes 5 can limit the connecting rods 6 to determine the installation position of the scraper 11, and a mounting plate 10 is fixed to one end of the connecting rod 6 close to the middle of the open groove 4, and a scraper 11 is fixed to the middle of the end close to the left and right mounting plates 10. The scraper 11 is brought into contact with the surface of the tire body 18 and then the tire body 18 is rotated to scrape the hair on the surface of the tire body 18. The end of the connecting rod 6 away from the open groove 4 is respectively fixed to the front and rear parts of the connecting plate 7 close to the bottom plate 1, and a servo cylinder 8 is fixed to the middle of the wall of the connecting plate 7 away from the bottom plate 1. The servo cylinder 8 can drive the connecting plate 7 to move left and right during operation, and the output ends of the servo cylinder 8 are respectively fixed to the middle of the left and right walls of the bottom plate 1.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the fixing mechanism 3 includes a mounting rod 12, which is respectively fixed on the left and right sides of the middle of the top wall of the base plate 1, a screw 15 is threadedly connected to the upper middle end of the right mounting rod 12, a movable plate 16 is rotatably connected to the left end of the screw 15, and a movable splint 17 is rotatably connected to the middle of the left wall of the movable plate 16, a driving motor 19 is fixed to the upper middle part of the left wall of the left mounting rod 12, and a fixed splint 20 is fixed to the output shaft of the driving motor 19, and the driving motor 19 will drive the fixed splint 20 to rotate during operation, thereby rotating the tire body 18 between the fixed splint 20 and the movable splint 17.

[0024] Further as Figure 3As shown, it is worth explaining in detail that the mounting rod 12 is respectively located in the middle of the left and right sides of the opening slot 4, the movable clamping plate 17 and the fixed clamping plate 20 are both located on the same horizontal line, and a torsion plate 13 is fixed to the right end of the screw rod 15. Setting the torsion plate 13 can reduce the difficulty of rotating the screw rod 15.

[0025] This scheme has the following working process: when it is necessary to remove hair from the tire body 18, first place the middle part of the tire body 18 between the movable clamping plate 17 and the fixed clamping plate 20, and then rotate the torsion plate 13. The rotation of the torsion plate 13 causes the screw 15 to rotate inside the right mounting rod 12, so that the screw 15 drives the movable plate 16 to move to the left. During the left movement of the movable plate 16, the tire body 18 is installed by the movable clamping plate 17 and the fixed clamping plate 20. After the tire body 18 is fixed, the servo cylinder 8 is started. The output end of the servo cylinder 8 is extended and retracted to cause the connecting plate 7 to move left and right on the outside of the bottom plate 1, thereby causing the connecting rod 6, the mounting plate 10 and the scraper 11 to move left and right. After the scrapers 11 on the left and right sides are attached to the outside of the tire body 18, the drive motor 19 is started, and the output shaft of the drive motor 19 rotates to cause the tire body 18 to rotate for automatic hair removal, so that tires of different sizes can be dehaired.

At the same time, with the cooperation of the mounting rod 12, the drive motor 19, the screw 15, the torsion plate 13, the limit rod 14, the movable clamping plate 17, the fixed clamping plate 20 and the movable plate 16, the tire body 18 can be quickly installed, thereby improving the installation efficiency of the tire body 18 and thus improving the tire scraping rate.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a tire body 18 is arranged between the movable clamping plate 17 and the fixed clamping plate 20, and the bottom of the tire body 18 is located inside the open groove 4, and the open groove 4 provides space for the installation of the automatic hair removal mechanism 2.

[0028] Further as Figure 1 As shown, it is worth explaining in detail that the scraper 11 is respectively located at the front and rear sides of the left and right parts of the lower end of the tire body 18, and bases 9 are fixed at the four corners of the bottom of the bottom plate 1. The base 9 can separate the bottom plate 1 from the ground, thereby preventing the tire body 18 from directly contacting the ground and affecting the hair removal operation.

[0029] Further as Figure 2As shown, it is worth explaining in detail that limiting rods 14 are fixed on both sides of the front and rear middle part of the right wall of the movable plate 16, and the limiting rods 14 respectively penetrate and are slidably connected to the front and rear ends of the top of the right mounting rod 12. The limiting rods 14 cooperate with the right mounting rod 12 to limit the movable plate 16, so that the movable plate 16 can remain stable during the movement.

[0030] In summary: the open groove 4 provides space for the installation of the automatic hair removal mechanism 2, and the base 9 is provided to separate the bottom plate 1 from the ground, thereby preventing the tire body 18 from directly contacting the ground and affecting the hair removal operation. The limit rod 14 cooperates with the right mounting rod 12 to limit the movable plate 16, so that the movable plate 16 can remain stable during the movement.

[0031] The drive motor 19 can be purchased on the market. The drive motor 19 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
