[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] The embodiment of the present utility model provides a tire depilatory device, which at least includes a cutter head assembly 1 for depilating a tire, such as Figure 1 As shown, the cutter head assembly 1 further includes a driving member 101, a connecting member 102, blades 104, and an outer cover 105. The connecting member 102 includes an inner cavity, in which an elastic member 103 is disposed. The bottom of the connecting member 102 is elastically connected to the driving member 101 via the elastic member 103. A plurality of blades 104 are evenly distributed around the circumference and fixedly connected to the top outer end surface of the connecting member 102. The driving member 101 drives the blades 104 to rotate through the connecting member 102. The outer cover 105 is sleeved over the blades 104 and has a plurality of small holes with a diameter not less than the diameter of the tire hair. Optionally, the elastic member 103 is a spring. The tire depilation device realizes an elastic connection between the connecting member 102 and the drive by providing an elastic member 103, realizes the elastic movement of the blade 104, and then realizes the flexible contact between the blade 104 and the tire contact surface, and can be fine-tuned to keep the cutter head in 90° contact with the tread. Further, by providing an outer cover 105, a small hole corresponding to the diameter of the fetal hair is opened on the outer cover 105, so that the fetal hair can enter smoothly and be removed by the rotating blade 104. At the same time, the outer cover 105 can also effectively prevent the blade 104 from damaging the tire surface, thereby realizing accurate, safe and efficient tire depilation. Optionally, the six blades 104 are evenly distributed circumferentially and fixedly connected to the top outer end face of the connecting member 102. The driving member 101 is preferably a servo motor. The tire depilation device is an active, safe and intelligent tire depilation machine. It is a device for removing fetal hair after the tire is formed and vulcanized. The device can be widely used in the depilation process of various tires such as semi-steel and full-steel radial tires. It should be noted that the cutter head assembly 1 is a three-dimensional movable and rotating self-cleaning cutter head assembly 1.

[0023] The tire hair removal device provided by the above technical solution uses rotary cutting to remove fetal hair. When the flexible cutter head assembly 1 contacts the vertically and slowly rotating tire tread, the fetal hair enters the rotary cutter through the mesh holes on the outer cover 105 and is cut off. Due to the effect of the protective net, the rotary cutter will not contact the tread, thereby protecting the tire. This overcomes the problem of existing tire hair removal devices causing tread damage during depilation, thereby affecting tire quality, and can safely and efficiently perform tire hair removal.

[0024] In order to improve the accuracy of hair removal, a laser rangefinder 2 is also included. The laser rangefinder 2 is installed side by side with the cutter head assembly 1, and can detect the distance between the rotating blade 104 and the tread in real time. It should be noted that those skilled in the art can try to conventionally select the installation position relationship between the laser rangefinder 2 and the cutter head assembly 1 according to the common knowledge in the field. This embodiment only provides one possible installation position form. In addition, the laser rangefinder 2 is not set in this embodiment for the purpose of high measurement accuracy, and in the actual hair removal process, the tire itself will jump during the hair removal process. Even if the laser rangefinder 2 is used, the accuracy of the measurement cannot be guaranteed. The laser rangefinder 2 of this technical solution is only set to measure the approximate distance, providing a possible implementation method to replace manual or other distance measurement methods, but not for accurate measurement.

[0025] like Figure 2 As shown, it also includes a bracket 3 for fixing the cutter head assembly 1, and a servo-driven lead screw pitch adjustment device 4 connected to the bracket 3, and the servo-driven lead screw pitch adjustment device 4 drives the bracket 3 to move left and right. Optionally, the servo-driven lead screw pitch adjustment device 4 is a lead screw slider device driven by a servo motor. Among them, the lead screw in the servo-driven lead screw pitch adjustment device 4 is an integrally processed left and right rotating lead screw. When the lead screw rotates, the left and right rotating nuts will drive the bracket 3 to move closer to and away from each other, that is, to approach the tire tread in the vertical direction and leave the tread at the same time. And there is a set of light rods in a parallel position of the lead screw, and a sliding bearing is provided on the bracket 3 to connect to the light rod and slide along to ensure that the bracket 3 does not rotate. In summary, a lead screw that drives the servo-driven lead screw pitch adjustment device 4 to move left and right is provided on the servo-driven lead screw pitch adjustment device 4, and a light rod that ensures the stability of the bracket 3 is also provided.

[0026] During the hair removal process, the entire bracket 3 moves left and right, forming a 90° spatial relationship with the vertical tire. The vertical tire will slowly rotate, thus forming a 90° motion relationship between the bracket 3 and the tire tread. During this process, the blade assembly 1 and the bracket 3 are flexibly connected in micro-motion. When approaching the slightly curved tread, it can flexibly conform to the tread. The blade assembly 1 itself is a rotating blade structure with an external steel mesh for protection. It uses a rotary cutter to remove the fetal hair, rather than other equipment pulling and tearing the fetal hair, just like a rotary razor, which can safely and quickly cut the beard, rather than using a razor to pull and remove the beard.

[0027] In order to further improve the accuracy of hair removal, a control device is also included, which is electrically connected to the laser rangefinder 2 and the servo-driven screw distance adjustment device 4. Optionally, the control device is a PLC programmable controller.

[0028] To improve the quality and efficiency of hair removal, the bracket 3 includes a bracket connection portion 301 connected to the blade assembly 1. The bracket connection portion 301 is curved, with two blade assemblies 1 positioned inside each end of the curved bracket connection portion 301. To further enhance hair removal quality, the inner bend angle of the bracket connection portion 301 matches the outer contour of the tire. To further improve hair removal efficiency, there are two bracket connection portions 301, one on each side of the tire.

[0029] Furthermore, it also includes a motor, a tire conveying device, and a tire clamping and positioning device, which are used to convey and fix the tire to be depilated.

[0030] The working process of the above tire depilation equipment is:

[0031] The connecting part 102 has a built-in elastic part 103 to achieve flexible contact between the cutter head (including the blade 104) and the tire surface, and can be fine-tuned to keep the cutter head in 90° contact with the tread. Six rotating blades 104 and an outer cover 105 are arranged in the cutter head. The outer cover 105 is provided with a gap equivalent to the diameter of the tire hair, so that the tire hair can enter smoothly and be cut off by the rotating blade 104 driven by the driving part 101.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
