Description

Technical Field

[0001] The utility model relates to the technical field of tire processing equipment, in particular to a tire pattern precision engraving device. Background Art

[0002] In the tire manufacturing industry, tire tread design and engraving are crucial. Tread patterns not only impact the tire's aesthetics but also directly impact its performance, such as grip, drainage, noise reduction, and driving stability. Therefore, efficiently and accurately engraving a well-designed tire pattern has always been a key concern for the tire manufacturing industry.

[0003] Traditional engraving methods also have shortcomings in tire clamping and positioning. If the tire is not clamped securely or positioned accurately during engraving, it can easily lead to deviations in the pattern engraving and even tire damage. This not only affects tire quality but also increases production costs and time.

[0004] Furthermore, traditional tire tread engraving methods often rely on manual or simple mechanical engraving, which present numerous drawbacks. Manual engraving is inefficient, and its accuracy is significantly affected by the worker's skill level, making it difficult to ensure consistent and accurate engraving. While simple mechanical engraving equipment improves engraving efficiency to a certain extent, it often lacks precision or has a limited adjustment range, making it unable to meet the demands of engraving complex patterns. This is particularly true for tires of varying sizes and specifications. Given this, we propose a device for precision tire tread engraving. Utility Model Content

[0026] As preferred of the embodiment, when the piston rod of two second hydraulic cylinders 14 extends to the longest, two clamping plates 11 are close, and the piston rod of two second hydraulic cylinders 14 moves synchronously.This design ensures that tyre is uniformly stressed in the process of clamping, avoids the deformation or displacement of tyre due to uneven clamping force, and further improves the accuracy and stability of engraving.

[0027] As preferred of the embodiment, the engraving tool assembly includes secondary adjustment mechanism 4 and primary adjustment mechanism for driving secondary adjustment mechanism 4 to move forward and backward, and secondary adjustment mechanism 4 is fixedly installed with installation frame 44, engraving motor 45 is fixedly installed in installation frame 44, and engraving cutter 46 is coaxially fixed on the output shaft of engraving motor 45.This design makes that engraving tool assembly not only can move in forward and backward direction, but also can be more finely adjusted through secondary adjustment mechanism 4, so as to realize the accurate engraving to tyre pattern.

[0028] As a preferred feature of this embodiment, the primary adjustment mechanism includes support plates 31 symmetrically fixedly connected to the top of the L-shaped support frame 3. A first screw rod 32 is rotatably mounted between the two support plates 31. A first adjustment motor 33, whose output shaft is coaxially fixed to the first screw rod 32, is fixedly mounted on one of the support plates 31. This design, in which the first adjustment motor 33 drives the first screw rod 32 to rotate, thereby driving the primary adjustment mechanism back and forth, enables coarse adjustment of the engraving knife assembly over a wide range, improving engraving flexibility and efficiency.

[0029] As a preferred feature of this embodiment, the secondary adjustment mechanism 4 includes a U-shaped frame 40. A drive block 41, threadedly connected to the first screw rod 32, is fixedly mounted at the top center of the U-shaped frame 40. The L-shaped support frame 3 is provided with a strip groove 30 that is slidably connected to the drive block 41. This design, through the sliding connection between the drive block 41 and the strip groove 30, and the connection between the U-shaped frame 40 and the primary adjustment mechanism, enables fine vertical adjustment of the engraving knife assembly, further improving engraving accuracy.

[0030] As a preferred embodiment of this embodiment, a second screw rod 48 is rotatably mounted within the U-shaped frame 40. A movable block 42 is threadedly connected to the second screw rod 48. The top of the movable block 42 is slidably connected to the top inner wall of the U-shaped frame 40. A second adjustment motor 47, whose output shaft is coaxially fixed to the second screw rod 48, is fixedly mounted on the outer wall of the U-shaped frame 40. This design allows the second adjustment motor 47 to rotate the second screw rod 48, thereby driving the movable block 42 to move within the U-shaped frame 40. This allows for fine horizontal adjustment of the engraving knife assembly. Combined with vertical adjustment, this allows for precise engraving at any location on the tire surface.

[0031] As a preferred embodiment of this embodiment, a first hydraulic cylinder 43 is fixedly connected to the bottom of the movable block 42, and a mounting frame 44 is fixedly mounted to the bottom of the first hydraulic cylinder 43. This design allows the height of the engraving knife assembly to be further adjusted through the telescopic movement of the first hydraulic cylinder 43, allowing the engraving knife to more accurately contact the tire surface, thereby improving the accuracy and effect of the engraving.

[0032] As a preferred embodiment of the present invention, a support leg 2 is fixedly installed at each of the four corners of the bottom of the placement box 1. This design ensures the stability and balance of the equipment, avoids engraving errors caused by shaking of the equipment during the engraving process, and improves the engraving quality.

[0033] When the utility model's tire pattern precision engraving equipment is used:

[0034] Equipment preparation: First, place the tire to be engraved in the placement box 1, ensuring that the center of the tire is aligned with the center of the two mounting shafts 13. By adjusting the four legs 2, ensure that the entire equipment is in a stable and balanced state to avoid shaking during the engraving process.

[0035] Tire clamping and positioning: The two second hydraulic cylinders 14 are activated, causing their piston rods to extend synchronously, pushing the two clamping plates 11 toward the tire and clamping it. The synchronized movement of the piston rods of the two second hydraulic cylinders 14 ensures uniform force during the tire clamping process, preventing deformation or displacement. Depending on the tire's size, the adjustment knob 18 is turned to slide the threaded rod 17 up and down within the fixed column 16, thereby adjusting the position of the curved support plate 31 so that it rests against the tire's inner wall, providing additional support and positioning for the tire and ensuring stability during the engraving process.

[0036] Tire rotation: The rotary motor 10 is started, and its output shaft rotates the mounting shaft 13 and the clamping plate 11, thereby driving the tire to rotate. The rotation of the tire enables the carving knife assembly to carve a continuous and complex pattern on the tire surface.

[0037] Adjustment and engraving of the knife assembly:

[0038] Coarse adjustment: The first screw rod 32 is driven to rotate by the first adjustment motor 33. Since the first screw rod 32 is threadedly connected to the driving block 41, and the driving block 41 is slidingly connected to the strip groove 30 on the L-shaped support frame 3, the rotation of the first screw rod 32 will drive the U-shaped frame 40 (that is, the secondary adjustment mechanism 4) to move in the front and rear directions, thereby realizing coarse adjustment of the engraving knife assembly and moving the engraving knife assembly to the approximate engraving position.

[0039] Fine Adjustment: Within the U-shaped frame 40, a second adjustment motor 47 drives a second screw rod 48 to rotate. Because the second screw rod 48 is threadedly connected to a movable block 42, which is slidably connected to the top inner wall of the U-shaped frame 40, the rotation of the second screw rod 48 drives the movable block 42 to move left and right within the U-shaped frame 40, achieving fine adjustment of the horizontal position of the chisel assembly. Simultaneously, the telescopic movement of the first hydraulic cylinder 43 further adjusts the height of the chisel assembly, ensuring more accurate contact between the chisel and the tire surface.

[0040] Engraving: After the carving knife assembly is adjusted to the right position, the carving motor 45 is started, and its output shaft drives the carving knife 46 to rotate and start carving the tire surface. By controlling the movement of the carving knife assembly and the rotation of the tire, complex and precise patterns can be carved.

[0041] Finished carving:

[0042] When the pattern carving on the tire surface is completed, the carving motor 45 is turned off to stop the rotation of the tire.

[0043] By reversing the second hydraulic cylinder 14, the clamping plates 11 are released from the tire, and the tire is then removed.

[0044] In summary, the tire pattern precision engraving equipment of the present invention can achieve precise engraving on the tire surface and improve the accuracy and efficiency of engraving through precise adjustment of the engraving knife assembly, stable tire clamping and positioning, and flexible tire rotation mechanism.
