Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to an automatic and efficient bonding device for engineering tire belt layers. Background Technology

[0002] In the precision manufacturing process of engineering radial tires, the design of the belt layer plays a crucial role. To endow the tire with excellent strength, stiffness, and impact resistance to cope with the harsh conditions of heavy machinery operation, the design angle of the belt layer is often carefully calculated and varied. This complex design requirement is fully reflected in the cutting process of the belt layer.

[0003] After adjusting the cutting angle according to the design, the machine will precisely cut out belt layer films with a specific trapezoidal shape. However, in order to ensure accurate splicing of the belt layers and prevent splicing misalignment (such as...), Figure 1 As shown in the figure, many engineering tire manufacturers in China still generally use manual adjustment to splice these trapezoidal belt layers together to form a continuous, flat belt layer with consistent angles.

[0004] In practice, experienced workers need to carefully observe with the naked eye to move and align adjacent trapezoidal belt layers, ensuring that the edges, angles, and overlapping areas meet the requirements before temporarily securing the overlap. After alignment, the machine performs the final sewing. The drawbacks of this method are obvious, mainly in the following three aspects:

[0005] First, the labor intensity for workers is high, and manual assembly is inefficient. Workers need to maintain focus and precise hand operation for long periods, repeatedly adjusting and comparing, which not only tests their physical strength and eyesight but also greatly limits production efficiency. Each assembly requires a significant amount of time and effort, making high-speed, continuous production difficult.

[0006] Secondly, the quality of the overlaps varies greatly, making it difficult to guarantee consistency. Because it relies entirely on manual visual judgment, even the most experienced workers are prone to deviations during the splicing process. A common problem is the "large head, small tail" phenomenon (e.g., Figure 2 (As shown). This uneven overlap not only affects the aesthetics of the belt layer, but more importantly, it directly affects the subsequent bonding and vulcanization effects, creating hidden dangers for the tire during use and increasing the risk of premature damage.

[0007] Finally, during the splicing process, workers are highly prone to causing the belt layers to curl and stick together, leading to numerous problems. The belt layer films typically possess a certain degree of stickiness and flexibility; during manual handling, accidental pulling or pressing can easily cause the films to curl and deform. Worse still, adjacent films may accidentally stick together due to improper handling, making separation difficult. This not only makes material unloading extremely difficult, further slowing down the production pace and reducing efficiency, but the curling and deformation themselves can also alter the original design angle of the belt layer, preventing the final formed belt layer from meeting the expected performance standards, creating a vicious cycle.

[0008] In conclusion, this method of manually splicing the belt layers has significant shortcomings in terms of labor intensity, product quality, and production efficiency, and has become a bottleneck restricting the further improvement of the manufacturing level of engineering radial tires. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic and efficient splicing device for engineering tire belt layers, which can quickly and accurately splice belt layers, reduce misalignment of joints, free up workers' labor, effectively improve the processing quality and efficiency of belt layers, and ensure the efficiency of tire forming.

[0010] The technical solution of this utility model is as follows:

[0011] An automatic and efficient bonding device for engineering tire belt layers includes a first conveyor belt and a second conveyor belt. A stitching pressure roller is installed above the second conveyor belt. A pad is installed in the gap between the first and second conveyor belts, and the belt layer is transferred from the first conveyor belt to the second conveyor belt through the pad. A telescopic push rod is installed on one side of the pad, and multiple rollers are installed at the end of the telescopic push rod. A positioning side plate is installed on the other side of the pad. When the belt layer is transferred to the pad, the telescopic push rod pushes the belt layer to the positioning side plate. A rear conveying side plate is installed behind the positioning side plate along the belt layer conveying direction. The rear conveying side plate is located on the side of the second conveyor belt, and several rollers are installed on the inner side of the rear conveying side plate. A laser width measuring instrument is installed on the side of the first conveyor belt, and a CCD camera is installed above it.

[0012] Preferably, the telescopic push rod is connected to a hydraulic cylinder.

[0013] Preferably, a guide plate is provided on the conveyor belt to guide the belt layer to the positioning side plate during the conveying process of the belt layer.

[0014] Preferably, along the conveying direction of the belt layer, a front conveying side plate is provided in front of the positioning side plate. The front conveying side plate is located on the side of the first conveyor belt, and a number of rollers are provided on the inner side of the front conveying side plate.

[0015] Preferably, a laser width measuring instrument is provided on the second side of the conveyor belt, and the laser width measuring instrument is located behind the sewing pressure roller along the conveying direction of the belt layer.

[0016] Preferably, a photoelectric sensor is provided on the telescopic push rod.

[0018] Compared with the prior art, this utility model has the following advantages:

It uses a laser width measuring instrument and a CCD camera to perform a quality inspection of the belt layers before bonding, preventing defective products from entering the splicing process.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0026] Example 1

[0027] like Figure 3As shown, this embodiment provides an automatic and efficient bonding device for engineering tire belt layers, including a first conveyor belt 1 and a second conveyor belt 2. A sewing pressure roller 3 is arranged above the second conveyor belt 2 (the first conveyor belt 1, the second conveyor belt 2, and the sewing pressure roller 3 are all existing production line equipment and will not be described in detail here). Multiple belt layers 14 are conveyed from the first conveyor belt 1 to the second conveyor belt 2. Two adjacent belt layers 14 are sewn together by the sewing pressure roller 3, and finally formed into a long strip belt layer 14, which is then rolled up for later use.

[0028] In this embodiment, in order to achieve automatic and efficient bonding of the belt layer 14, the following method is adopted:

[0029] like Figure 3 As shown, a laser width measuring instrument 12 is installed on the side of conveyor belt 1, and a CCD camera is installed above it. The laser width measuring instrument 12 and the CCD camera measure the width and side tilt angle of the trapezoidal belt layer 14 on conveyor belt 1 to determine if it is within the allowable width and angle range. If it is, the belt layer 14 is deemed qualified and continues to be conveyed forward; otherwise, it is deemed unqualified (e.g., ...). Figure 4 As shown, the width of the belt layer 14 detected by the laser width measuring instrument 9 is obviously too narrow. At this time, the control system alarms and stops. After the staff removes the defective belt layer 14, the system continues to run.

[0030] like Figure 3 As shown, a stainless steel pad 4 is horizontally placed in the gap between conveyor belt 1 and conveyor belt 2. The belt layer 14 is transferred from conveyor belt 1 to conveyor belt 2 via the pad 4. A telescopic push rod 5 driven by a hydraulic cylinder is provided on one side of the pad 4. Multiple rollers 6 are provided at the end of the telescopic push rod 5. When the belt layer 14 is transferred to the telescopic push rod 5, the side of the belt layer 14 contacts the rollers 6, and the rollers 6 can greatly reduce the friction between the belt layer 14 and the telescopic push rod 5, without affecting the transfer of the belt layer 14. A stainless steel positioning side plate 7 is provided on the other side of the pad 4. When the belt layer 14 is transferred to the pad 4, the telescopic push rod 5 pushes the belt layer 14 to the positioning side plate 7, that is, one side of the belt layer 14 contacts the rollers 6 and the other side is attached to the positioning side plate 7, thereby aligning the edges of all the belt layers 14, which facilitates the subsequent joining of the belt layers 14 by the sewing pressure roller 3.

[0031] like Figure 3As shown, a rear conveyor side plate 8 is provided behind the positioning side plate 7 along the conveying direction of the belt layer 14. The rear conveyor side plate 8 is located on the side of the second conveyor belt 2 and has several rollers 6 on its inner side. After the belt layer 14 is pushed to fit the positioning side plate 7 by the telescopic push rod 5, its side continues to be conveyed on the second conveyor belt 2 with its side against the rollers 6 on the rear conveyor side. When the sides of two adjacent belt layers 14 are conveyed to the sewing pressure roller 3 by the second conveyor belt 2, the first conveyor belt 1 and the second conveyor belt 2 stop conveying. Then, the sewing pressure roller 3 presses the sides of the two belt layers 14 to sew them together. The telescopic push rod 5 is reset under the drive of the hydraulic cylinder, and the first conveyor belt 1 and the second conveyor belt 2 continue to convey until the next belt layer 14 is conveyed to the telescopic push rod 5. The above operation is repeated.

[0032] In this embodiment, a laser width measuring instrument 9 and a CCD camera are used to perform a conformity test on the belt layer 14 before stitching to prevent unqualified products from entering the splicing process. Furthermore, this embodiment uses a telescopic push rod 5 and a positioning side plate 7 to align the edges of all belt layers 14, ensuring accurate alignment of the belt layers 14, reducing manual intervention, improving positioning accuracy, and increasing production efficiency.

[0033] Example 2

[0034] Based on Example 1, such as Figure 3 As shown, a guide plate 10 is provided on conveyor belt 1. A front conveyor side plate 11 is positioned in front of the positioning side plate 7 along the conveying direction of the belt layer 14. The guide plate 10 is located in front of the front conveyor side plate 11, which is located on the side of conveyor belt 1. Several rollers 6 are arranged on the inner side of the front conveyor side plate 11. During the conveying process of the belt layer 14, the guide plate 10 guides the belt layer 14 to the front conveyor side plate 11. The side of the belt layer 14 continues to be conveyed along the rollers 6 to the positioning side plate 7, ensuring that the edges of the belt layer 14 are aligned.

[0035] Example 3

[0036] Based on Example 1, such as Figure 3 As shown, a laser width measuring instrument 212 is installed on the side of the conveyor belt 2. Along the conveying direction of the belt layer 14, the laser width measuring instrument 212 is located behind the sewing pressure roller 3.

[0037] The sewn belt layer 14 continues to be conveyed forward to the laser width measuring instrument 2. The laser width measuring instrument 2 12 can measure its width. When the measured width meets the allowable tolerance range, the sewn belt layer 14 is deemed qualified; otherwise, it is deemed unqualified (e.g., ...). Figure 4 As shown, the width of the sewn belt layer 14 detected by the laser width measuring instrument 212 is significantly too wide. At this point, the control system alarms and stops the machine. The workers then cut the two sewn belt layers 14 apart and rejoin them. The laser width measuring instrument 212 prevents misaligned products from entering the next process, thus maintaining product quality.

[0038] Example 4

[0039] Based on Example 1, such as Figure 3 As shown, a photoelectric sensor 13 is installed on the telescopic push rod 5. When the photoelectric sensor 13 senses that the belt layer 14 has been delivered to the position, the hydraulic cylinder drives the telescopic push rod 5 to advance towards the belt layer 14. After the sewing pressure roller 3 sews the belt layer 14, the hydraulic cylinder drives the telescopic push rod 5 to reset until the photoelectric sensor 13 senses that the next belt layer 14 has been delivered.
