Description

Technical Field

[0001] This utility model relates to the technical field of tire tread printing devices, and in particular to a tire tread printing device. Background Technology

[0002] The outer tire is the ring-shaped outer shell of an inflatable tire. Its function is to bear the vehicle load, prevent the inner tube from bulging after inflation, limit the outer edge size of the tire, and protect the inner tube from mechanical damage.

[0003] After production, tires are usually printed on their outer walls. However, existing printing systems generally do not have a device to position the tire, causing it to move during the printing process and reducing the stability of the printing operation. Some systems that do have a device to fix the tire cannot lift or lower it, thus making it impossible to print on tires of different thicknesses and reducing the adaptability of the device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By moving multiple positioning plates in multiple moving slots, the multiple positioning plates come into contact with the inner wall of the tire, thereby fixing the tire and ensuring the stability of the tire during the printing process. This invention provides a tire tread printing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the lifting mechanism includes a lifting plate that is slidably connected through the through groove, and a through rod is provided at the upper end of the lifting plate, which passes through the upper end of the positioning plate and is slidably connected thereto.

[0008] Preferably, the moving mechanism includes a moving screw that is rotatably connected between the moving groove and the recess, the moving screw passing through the positioning plate and threadedly connected thereto, and each of the multiple moving screws having a bevel gear at one end located in the recess.

[0009] Preferably, a fixing frame is provided in the groove, a power motor is provided in the fixing frame, a bevel gear ring is provided on the outer wall of the output shaft of the power motor, and multiple bevel gears mesh with the bevel gear ring.

[0010] Preferably, a lifting screw is rotatably connected to the upper end of the fixed frame, and a connecting sleeve is threaded onto the outer wall of the lifting screw.

[0011] Preferably, the outer wall of the connecting sleeve is provided with multiple fixing plates, and each of the multiple fixing plates is slidably connected to a movable plate through its end. The upper ends of the multiple through rods are respectively connected to the multiple movable plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. By moving multiple positioning plates within multiple movable slots, the positioning plates contact the inner wall of the tire, thereby fixing the tire and ensuring its stability during the printing process.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-3 A tire tread printing device includes a base 1, a rotating groove 2 at the upper end of the base 1, a rotating plate 3 rotatably connected in the rotating groove 2, a printing device 4 at the upper end of the base 1, a letter mold 5 on the side wall of the printing device 4, and multiple circumferentially arranged moving grooves 6 at the upper end of the rotating plate 3. Positioning plates 9 are slidably connected in each of the multiple moving grooves 6, and each of the multiple positioning plates 9 has a through groove 11. Each of the multiple through grooves 11 has a lifting mechanism for lifting the tire. The lifting mechanism includes a lifting plate 12 that is slidably connected through the through groove 11, and a through rod 10 at the upper end of the lifting plate 12. The through rod 10 passes through the upper end of the positioning plate 9 and is slidably connected to it. By having the multiple through rods 10 pull the multiple lifting plates 12 to raise and lower, the effect of raising and lowering the tire is achieved, allowing the device to fix tires of different widths and improving the adaptability of the device.

[0022] The upper end of the rotating plate 3 is provided with a groove 8. Multiple moving slots 6 are provided with a moving mechanism between the groove 8 for moving the positioning plate 9. The moving mechanism includes a moving screw 7 that is rotatably connected between the moving slot 6 and the groove 8. The moving screw 7 passes through the positioning plate 9 and is threadedly connected to it. Each end of the multiple moving screws 7 located in the groove 8 is provided with a bevel gear 13. By moving the multiple positioning plates 9 in the multiple moving slots 6 respectively, the multiple positioning plates 9 are made to contact the inner wall of the tire, thereby fixing the tire and ensuring the stability of the tire during the printing process.

[0023] A fixing frame 18 is provided in the groove 8, and a power motor 19 is provided in the fixing frame 18. A bevel gear ring 20 is provided on the outer wall of the output shaft of the power motor 19, and multiple bevel gears 13 mesh with the bevel gear ring 20.

[0024] A lifting screw 17 is rotatably connected to the upper end of the fixed frame 18, and a connecting sleeve 16 is threadedly connected to the outer wall of the lifting screw 17.

[0025] The outer wall of the connecting sleeve 16 is provided with multiple fixing plates 14, and each of the multiple fixing plates 14 is slidably connected to a movable plate 15 through its end. The upper ends of multiple through rods 10 are respectively connected to multiple movable plates 15.

[0026] When using this invention, during the printing operation on the tire, the tire is placed on the upper end of the rotating plate 3, and the power motor 19 is started, causing the bevel gear ring 20 on the outer wall of its output shaft to rotate. The bevel gear ring 20 meshes with multiple bevel gears 13, causing the multiple bevel gears 13 to rotate and drive multiple moving screws 7 to rotate. The moving screws 7 are threadedly connected to the positioning plates 9, causing the multiple positioning plates 9 to move in multiple moving slots 6 respectively, thereby making the multiple positioning plates 9 contact the inner wall of the tire, thus fixing the tire and ensuring the stability of the tire during the printing operation (since the cooperation between the printing device 4 and the letter mold 5 is existing technology, the relevant structure is not described in detail in this figure).

[0027] When printing on tires of different thicknesses, the lifting screw 17 is rotated. The threaded connection between the lifting screw 17 and the connecting sleeve 16 allows the connecting sleeve 16 to move up and down within the range of the lifting screw 17. Then, through the connection between multiple fixed plates 14 and moving plates 15, the moving connecting sleeve 16 drives multiple through rods 10 to move. The multiple through rods 10 pull multiple lifting plates 12 to rise and fall, thereby achieving the effect of raising and lowering the tire. This allows the device to fix tires of different widths and improves the adaptability of the device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
