[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0016] Reference Figure 1-3 As shown, a tire dynamic marking device includes a housing 1, a movable seat 3, slide rods 4, a compression spring 8, and a telescopic device 9. The housing 1 has a transverse guide rail 2 inside, and a through hole 101 is opened on its bottom plate. The movable seat 3 is slidably connected to the guide rail 2 and is connected to a drive mechanism. Three slide rods 4 are arranged in a linear array along the transverse direction on the movable seat 3 and are located on the same vertical plane as the through hole 101. The slide rods 4 slide vertically through the movable seat 3, and have a boss 5 at their upper end and a limiting plate 6 at their lower end. A printing probe 7 is installed at the bottom of the limiting plate 6. When the printing probe 7 is facing the through hole 101, it and the limiting plate 6 can pass through the through hole 101. The compression spring 8 is sleeved on the slide rods 4, and its upper and lower ends are respectively supported by the bottom of the boss 5 and the top of the movable seat 3.

[0017] The telescopic device 9 is vertically fixed to the top plate of the housing 1, and its output rod passes through the top plate of the housing 1. The lower end of the output rod is provided with a pressure block 10 facing the through hole 101. Specifically, in this embodiment, the telescopic device 9 is a cylinder.

[0018] The drive mechanism includes a rack 11 and a first motor 13. The rack 11 is arranged parallel to the guide rail 2 and is fixed on the movable seat 3. The first motor 13 is fixed on the inner wall of the housing 1, and a gear 12 that meshes with the rack 11 is fixedly mounted on its output shaft. Specifically, the first motor 13 is a servo motor or a stepper motor.

[0019] When the tire enters the marking station, the control system controls the designated printing probe 7 to be aligned with the through hole 101 based on the tire information: the first motor 13 is started to drive the gear 12 to rotate, which drives the moving seat 3 to move along the guide rail 2 through the rack 11 until the designated printing probe 7 is aligned with the through hole 101; then the housing 1 moves to the marking position, the control system controls the cylinder to act, the cylinder rod extends, and the pressure block 10 presses down the boss 5 corresponding to the printing probe 7, so that the printing probe 7 extends out of the through hole 101 and marks the tire with the help of the ribbon 18; after the marking is completed, the cylinder resets, and the printing probe 7 is reset under the action of the compression spring 8; then the ribbon 18 moves to one point, ready for the next marking. Example 2

[0020] As a preferred embodiment of this utility model, this embodiment adds a ribbon 18 take-up and release component based on embodiment one, specifically as follows: Reference Figure 1-2 As shown, this embodiment also includes a ribbon 18 take-up and untake-down assembly located on the outside of the housing 1. The ribbon 18 take-up and untake-down assembly includes a damping roller 14, a guide roller 15, and a second motor 17. The damping roller 14 and the second motor 17 are respectively installed on the left and right sides of the housing 1, and a take-up roller 16 is fixedly mounted on the output shaft of the second motor 17. Two guide rollers 15 are respectively installed on the left and right sides of the bottom of the housing 1, and the two are on the same horizontal plane. The damping roller 14, the guide roller 15 and the take-up roller 16 are all arranged longitudinally and are located on the same vertical plane as the through hole 101.

[0021] Specifically, the second motor 17 is a servo motor or a stepper motor.

[0022] Install the ribbon 18 before marking: Put the ribbon roll onto the damping roller 14, then wrap the ribbon 18 around the two guide rollers 15 in sequence, and finally fix the end of the ribbon 18 onto the take-up roller 16.

[0023] When the housing 1 moves to the dotting position, the ribbon 18 on the lower side of the through hole 101 adheres to the tire sidewall. Then, the control system controls the cylinder to move, so that the designated printing probe 7 extends out of the through hole 101 and marks the tire with dots by cooperating with the ribbon 18. After the dotting is completed, the second motor 17 starts to drive the take-up roller 16 to rotate, so that the ribbon 18 moves one dot. Example 3

[0024] As a preferred embodiment of this utility model, the difference between this embodiment and Embodiment 2 lies in the driving mechanism, specifically: In this embodiment, the driving mechanism is an electric push rod, which is arranged parallel to the guide rail 2 and fixed to the side plate of the housing 1. Its output rod passes through the side plate of the housing 1 and is connected to the movable seat 3.

[0025] When switching the print probe 7, the electric push rod is activated, which drives the moving seat 3 to move along the guide rail 2 through the output rod until the designated print probe 7 is aligned with the through hole 101.

[0026] In summary, this device drives the movable seat 3 to move along the guide rail 2 via the drive mechanism, which can complete the conversion of the printing probe 7. After the dot is printed, the ribbon 18 only needs to travel one dot, thus solving the problem of wasting the ribbon 18.

[0027] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
