[0001] The utility model relates to the technical field of tire retreading engraving devices, in particular to an engraving and marking device for tire retreading. Background Art

[0002] With the continuous development of modern society, the number of cars is also increasing, so the use and demand for tires are also increasing. The tires of large cars may be replaced after long-term use, and the replaced tires can be refurbished and used again. In order to ensure that the car has better grip during driving, refurbished tires usually have patterns engraved on the surface of the tire to increase friction, such as a kind of engraving machine for tire surface patterns proposed in Chinese Patent 202221804185.8. In the above scheme, the tire is fixed and limited by an uncoiler, and then the tire is engraved by a carving knife. However, when the uncoiler fixes the tire, it can only fix the top and bottom of the tire, and the front and back of the tire cannot be fixed, which may cause the tire to shake back and forth when refurbishing and engraving, thereby affecting the normal operation of the carving knife and reducing the tire refurbishing and engraving speed.

[0033] See also Figure 3 and Figure 4 The fixing mechanism 5 is installed at equal intervals outside the unwinding unit 4 to reinforce the inside of the tire.

[0034] The fixing mechanism 5 includes a transverse plate 51, which is used to fix the tire. Both sides of the top of the transverse plate 51 are rotatably connected to the second rollers 52. The second rollers 52 are used to facilitate the tire to slide on the outside of the transverse plate 51. The front and back sides of the second roller 52 are fixedly connected to the outer spherical bearings 521 with seats. The outer spherical bearings 521 with seats are connected to the inside of the transverse plate 51, and the outer spherical bearings 521 with seats can support the second rollers 52.

[0035] Transverse grooves 53 are provided on both sides of the transverse plate 51, and the transverse grooves 53 are convenient for storing the limiting plates 54. The interior of the transverse grooves 53 is slidably connected to the limiting plates 54, and the limiting plates 54 are convenient for reinforcing the tire. The end of the limiting plate 54 away from the inclined rod 55 is fixedly connected to a second rubber pad 542, and the second rubber pad 542 is a square rubber pad. The second rubber pad 542 facilitates the limiting plate 54 to be inserted into the interior of the tire to fix the front and back sides of the tire.

[0036] The top of the limiting plate 54 is fixedly connected with a first rubber pad 541, and the first rubber pad 541 is a directional rubber pad. The first rubber pad 541 can improve the limiting effect of the limiting plate 54 on the second roller 52. The bottom of the limiting plate 54 is connected with an inclined rod 55 through a hinge. The inclined rod 55 is used to transmit the limiting plate 54. The bottom of the inclined rod 55 is connected to the outside of the unwinding unit 4 through a hinge. The bottom of the cross plate 51 is evenly connected with sliding arms 56.

[0037] The outside of the sliding arm 56 is sleeved with a sleeve 57, the bottom of the sleeve 57 is fixedly connected to a connecting frame 561, the top of the connecting frame 561 is connected to the outside of the uncoiler unit 4 through the connecting arm, the connecting frame 561 can support and fix the sleeve 57, the sleeve 57 is connected to the outside of the uncoiler unit 4, and the bottom of the sliding arm 56 is fixedly connected to a spring 58.

[0038] The bottom of the spring 58 is connected to the bottom of the sleeve 57. The slide arm 56 and the sleeve 57 can guide the cross plate 51 so that the cross plate 51 can move linearly outside the unwinding unit 4. The slide arm 56 is installed outside the unwinding unit 4 to fix one end of the tire pressure plate. The spring 58 can drive the cross plate 51 to return. This case is aimed at refurbishing and engraving large tires.

[0039] In this scheme, the tire is first picked up and placed on the top of the base 1, and then the tire is pushed to the end close to the unwinding unit 4, so that the tire is set outside the unwinding unit 4, and the unwinding unit 4 is started to insert the unwinding unit 4 into the inside of the tire to fix the tire. After the unwinding unit 4 fixes the tire, it drives the tire to rotate, and the engraving unit 3 is started to perform engraving processing on the outside of the tire;

[0040] When the uncoiler unit 4 fixes the tire, the top of the cross plate 51 contacts the inside of the tire, and then the rising uncoiler unit 4 drives the limit plate 54 to transmit, and the transmission inclined rod 55 drives the limit plate 54 to move, and the moving limit plate 54 is inserted into the front and back of the tire, and then the front and back of the tire are fixed. Through the added fixing mechanism 5, when the tire is fixed by the uncoiler unit 4, the fixing mechanism 5 is automatically driven to move, and the uncoiler unit 4 is cooperated to fix the inside of the tire at three points, thereby preventing the tire from shaking when it is fixed and engraved by the uncoiler unit 4.

[0041] A second roller 52 is provided on the top of the transverse plate 51. The second roller 52 facilitates the feeding and unloading of the tire outside the unwinding unit 4. When the tire is fixed, the limit plate 54 extends to contact the bottom of the second roller 52, thereby limiting the rotation of the second roller 52. Through the added limit plate 54, when the fixing mechanism 5 fixes the tire at three points as a whole, the second roller 52 is automatically limited by the second roller 52. When the tire is fixed, the second roller 52 is prevented from continuing to rotate, resulting in unstable tire fixation. At the same time, the second roller 52 is prevented from rotating when the tire is fixed, thereby avoiding wear on the inside of the tire.
