Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and specifically relates to an automatic tire tread marking device. Background Technology

[0002] In tire manufacturing, several different colored lines are typically drawn on the tire tread. This is done to distinguish tires of different sizes using different colored lines, making them easily identifiable and readily identifiable by machines. These lines are usually drawn during the production of the tread components, and then fixed to the finished tire tread after molding and vulcanization.

[0003] Current tire marking equipment typically relies on manual adjustment of the marking wheel position to mark treads of different sizes. Manual adjustment has several drawbacks: 1. Low efficiency, as each marking mechanism requires individual adjustment; 2. Low accuracy in manually adjusted marking wheel positions; 3. The paint cartridge and paint container also require manual replacement. While a patent with publication number CN116690520A allows for automatic specification adjustment using a motor, it cannot compensate for tread rubber delivery misalignment. If the tread rubber delivery is off-center, the marking position will be inaccurate. Furthermore, the paint cartridge moves with the marking wheel adjustment, increasing the risk of leakage. The weight of the paint cartridge on the marking wheel also affects the pressure between the marking wheel and the tread rubber, thus impacting the marking effect. Additionally, the paint container also requires manual replacement.

[0004] Therefore, this application provides an automatic tire tread marking device, which aims to improve the accuracy of tire tread marking, reduce the need for manual labor, and thus improve production efficiency. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0039] like Figure 1 As shown, an automatic tire tread marking device includes: a conveyor 1, a tire tread compound 2, a working head adjustment mechanism 3, an edge detection mechanism 4, and a marking assembly 5;

[0040] The conveyor 1 is used to transport the tread rubber 2;

[0041] The working head adjustment mechanism 3 is arranged horizontally above the conveyor 1, and the marking assembly 5 is provided on the working head adjustment mechanism 3;

[0042] The edge detection mechanism 4 is used to obtain the edge position information of the tread rubber 2;

[0043] The working head adjustment mechanism 3 is used to adjust the position between the marking assembly 5 and the tread rubber 2 according to the edge position information;

[0044] The marking assembly 5 is connected to an external pigment container via a delivery pipe and is used to mark lines on the surface of the tread rubber 2.

[0045] The edge detection mechanism 4 accurately determines the edge position of the tread rubber 2. Based on this information, the working head adjustment mechanism 3 precisely adjusts the position of the marking component 5, enabling it to accurately mark lines at designated positions on the surface of the tread rubber 2. This ensures the positional accuracy of the markings, avoids positional deviations that may occur due to manual operation, and improves product consistency and quality stability. Furthermore, this device is highly automated. From the conveying of the tread rubber 2, edge position detection, and adjustment of the marking component 5 to the final marking operation, most of the work is completed automatically, reducing reliance on manual labor. Enterprises can reduce manpower investment in related positions, lower labor costs, increase production efficiency, and reduce worker fatigue.

[0046] like Figure 2 As shown, the working head adjustment mechanism 3 includes: a first mounting frame 301 that spans across the conveyor 1 and is fixedly connected to the conveyor 1;

[0047] A pair of vertical slide rods 302 are provided on one side of the first mounting bracket 301. A first mounting plate 303 is slidably connected to the vertical slide rods 302. An up-and-down adjusting screw 304 is threadedly connected to the upper part of the first mounting bracket 301. The lower end of the up-and-down adjusting screw 304 is rotatably connected to the first mounting plate 303 through a floating joint.

[0048] A left-right adjustment component is provided on the side of the first mounting plate 303 away from the first mounting bracket 301, and the left-right adjustment component is provided with the scribing component 5.

[0049] The vertical position adjustment of the marking assembly 5 can be achieved by the vertical adjustment screw 304 on the first mounting bracket 301 and the first mounting plate 303 rotating through the floating joint. Since the first mounting plate 303 is slidably connected to the vertical slide bar 302, the first mounting plate 303 will move up and down along the vertical slide bar 302 when the vertical adjustment screw 304 is rotated.

[0050] This allows the marking assembly 5 to be adjusted to a suitable height position according to materials of different heights or different marking process requirements, greatly improving the equipment's adaptability to materials of different specifications. Since frequent adjustments are not required once the position is set, there is no need for automatic adjustment using a motor. If automatic adjustment is required, simply replacing the handwheel with a motor will achieve automatic adjustment.

[0051] like Figure 2As shown, the left and right adjustment assembly includes: a pair of horizontally spaced horizontal slide rods 305 on the first mounting plate 303; a left and right adjustment screw 306 is rotatably connected to the middle of the first mounting plate 303; and a first screw motor 307 is fixedly connected to one side of the first mounting plate 303. The first screw motor 307 is used to drive the left and right adjustment screw 306 to rotate.

[0052] A base 308 is slidably connected to the horizontal slide bar 305. The middle part of the base 308 is threadedly connected to the left and right adjusting screw 306. The scribing assembly 5 is provided on the base 308.

[0053] The threaded connection between the left / right adjusting screw 306 and the base 308 converts the rotational motion of the screw into the linear motion of the base 308. The screw drive offers high transmission precision. By precisely controlling the number of rotations and angle of the left / right adjusting screw 306 driven by the first screw motor 307, the movement distance of the base 308 on the horizontal slide bar 305 can be precisely controlled. This allows the scribing assembly 5 to accurately move to the desired scribing position on the material, greatly improving the lateral accuracy of the scribing.

[0054] like Figure 3 As shown, the marking assembly 5 includes: a marking rod 501, a marking cylinder 502, and a marking wheel 503;

[0055] One end of the marking rod 501 is rotatably connected to the base 308, and the other end is fixedly connected to the marking wheel 503. One end of the marking cylinder 502 is rotatably connected to the base 308, and the other end is rotatably connected to the middle of the marking rod 501. The marking wheel 503 is connected to an external paint bucket through a delivery pipe.

[0056] One end of the scribing rod 501 is rotatably connected to the base 308, and both ends of the scribing cylinder 502 are rotatably connected to the base 308 and the middle of the scribing rod 501, respectively. By controlling the extension and retraction of the scribing cylinder 502, the swing of the scribing rod 501 can be easily controlled, and scribing can be started or stopped at any time. In practical applications, the pressure between the scribing wheel 503 and the material surface can be flexibly adjusted by setting the pressure of the scribing cylinder 502 to achieve the best scribing effect.

[0057] like Figure 4 As shown, the edge detection mechanism 4 includes: a second mounting frame 401 that spans across the conveyor 1 and is fixedly connected to the conveyor 1;

[0058] A second mounting plate 402 is fixedly connected to the upper part of the second mounting bracket 401. A detection screw 403 is horizontally rotatably connected to the second mounting plate 402. A detection motor 404 is fixedly connected to one side of the second mounting plate 402. The detection motor 404 is used to drive the detection screw 403 to rotate. A detection nut seat 405 is slidably connected to the second mounting plate 402. The middle part of the detection nut seat 405 is threadedly connected to the detection screw 403. A third mounting plate 406 is fixedly connected to the detection nut seat 405. An edge sensor 407 is fixedly connected to the third mounting plate 406. The edge sensor 407 is used to obtain the edge information of the tread rubber 2.

[0059] The detection motor 404 drives the detection screw 403 to rotate, which in turn causes the detection nut seat 405 to slide precisely along the second mounting plate 402. This allows the edge sensor 407 to be precisely adjusted in the horizontal direction, adapting to the edge detection requirements of tread rubber 2 with different widths and positions, and accurately acquiring the position information of the edge of the tread rubber 2. The working head adjustment mechanism 3 can move the scribing component 5 to a preset position inside the tread rubber 2 according to preset parameters and the position information of the edge of the tread rubber 2, and perform scribing operation at the preset position without manual adjustment.

[0060] like Figure 4 As shown, limit sensors 408 are respectively provided on both sides of the second mounting plate 402. The limit sensors 408 are used to prevent the detection nut seat 405 from colliding with the two ends of the second mounting plate 402. The detection nut seat 405 slides along the second mounting plate 402 under the drive of the detection screw 403. Without the limit sensors 408 to limit it, the detection nut seat 405 may slide excessively due to control errors or unexpected situations, eventually colliding with the two ends of the second mounting plate 402. Such a collision may cause damage to the detection nut seat 405, the second mounting plate 402, and related connecting parts, such as screw deformation and nut damage. The limit sensors 408 can detect the detection nut seat 405 approaching the two ends of the second mounting plate 402 in time and send a signal to stop the detection motor 404, thereby avoiding hardware damage, extending the service life of the equipment, and reducing the maintenance cost of the equipment.

[0061] like Figure 1 As shown, the conveyor 1 is also equipped with a coding assembly, which includes a working head adjustment mechanism 3 and a coding printer 6. The coding printer 6 is fixedly connected to the base 308 in the working head adjustment mechanism 3. The tread rubber 2 generally needs to be sprayed with barcodes or QR codes for machine recognition. In this solution, simply replacing the marking assembly 5 with the coding printer 6 will convert it into a coding assembly.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
