Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing equipment, and in particular to a novel device for producing low-hardness and low-height tire beads. Background Technology

[0002] With the rapid development of the automotive industry, consumers have increasingly higher requirements for tire comfort and NVH (noise, vibration, and harshness) performance. To meet market demands, tire manufacturers are constantly improving tire design, one important direction being reducing the height and stiffness of the bead triangle. Lower stiffness and lower bead height can provide better shock absorption, improve ride comfort, and reduce noise and vibration during vehicle operation.

[0003] However, existing equipment for producing tire bead mainly uses vertical extrusion feeding. This method is suitable for producing triangular rubber with a certain degree of hardness. When the hardness and height of the triangular rubber decrease, the vertical feeding method can easily cause the triangular rubber to collapse during the feeding process, thereby affecting the subsequent automatic cutting and bonding processes, resulting in low production efficiency or even interruption. Utility Model Content

[0004] In view of the fact that the existing vertical extrusion feeding equipment cannot effectively produce tire bead triangles with low hardness and low height, thus limiting the production of high comfort tires, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a new type of equipment for producing low-hardness and low-height tire beads. Its purpose is to solve the problem that existing vertical extrusion feeding equipment cannot effectively produce low-hardness and low-height tire bead triangles, which limits the production of high-comfort tires.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel equipment for producing low-hardness and low-height tire bead, including a tire bead body and an installation mechanism, and further including a processing mechanism and an ejection mechanism. The installation mechanism includes a rotating mounting block, and a sliding ring is slidably installed on the outer side of the rotating mounting block. The processing mechanism includes a discharge pipe head, an extrusion plate, a fixed frame, and a scraper. The discharge pipe head is horizontally fixedly installed on one side of the equipment. An extrusion roller is rotatably installed on the inner side of the fixed frame. The scraper is movably installed on one side of the fixed block through a telescopic rod. The ejection mechanism includes a top block fixedly installed inside the sliding ring, and the rotating mounting blocks are provided in several groups, with top grooves opened between the several groups of rotating mounting blocks.

[0007] In a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, the lower part of the rotating mounting block is driven and installed at the output end of the first motor.

[0008] As a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, a fixing plate is fixedly installed on the lower outer side of the rotating mounting block, and a first electric push rod is fixedly installed on the upper surface of the fixing plate.

[0009] In a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, the sliding ring is fixedly installed at the output end of the first electric push rod.

[0010] In a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, the tire bead body is mounted on the upper outer side of the rotating mounting block.

[0011] As a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, the extrusion plate is fixedly installed at the telescopic end of the second electric push rod, the second electric push rod is fixedly installed on the inner side of the equipment, and the extrusion plate is used to tightly press the tire bead against the surface of the rotating mounting block to prevent displacement during tire bead processing.

[0012] As a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, a second motor is fixedly installed on the inner side of the fixed frame, a drive gear is driven and installed at the output end of the second motor, a toothed block is fixedly installed at one end of the extrusion roller, and the extrusion roller meshes with the drive gear through the toothed block.

[0013] In a preferred embodiment of the novel equipment for producing low-hardness and low-height tire bead as described in this utility model, a spring structure is installed on the surface of the telescopic rod.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its processing mechanism, delivers the tire bead body via a discharge pipe head. A second electric push rod extends, causing the extrusion plate to tightly press the tire bead body against the surface of the rotating mounting block. After the extrusion roller presses the triangular rubber onto the surface of the tire bead body, a spring structure and telescopic rod press a scraper against the outer surface of the tire bead body to remove excess rubber. This innovative design, combining horizontal feeding and the extrusion roller with the scraper, solves the problem of low-hardness triangular rubber collapsing, ensuring uniform adhesion of the triangular rubber to the tire bead body. Simultaneously, it automatically removes excess rubber, enabling continuous and stable production of high-comfort tires and improving production efficiency and product quality.

[0015] 2. This utility model, through its installation and ejection mechanisms, allows the tire bead body to be installed on the surface of the rotating mounting block. The first electric push rod shortens, causing the sliding ring to slide downwards. After the sliding ring loses its pressure, the rotating mounting block slides outwards, increasing its inner diameter and providing internal support for the tire bead body. After the triangular rubber is extruded, the first electric push rod extends, causing the sliding ring to slide upwards and press the rotating mounting block inwards, reducing its inner diameter. This weakens the internal support for the tire bead body. Simultaneously, the sliding ring drives the top block to eject the tire bead body upwards within the top groove, achieving automatic discharge. This realizes automatic internal support for fixing and releasing the tire bead body, ensuring stability during processing and automatically ejecting the finished product after the triangular rubber is extruded. This significantly improves loading and unloading efficiency, reduces manual labor intensity, and achieves automation and continuity in the production process. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1

[0019] Reference Figure 1 , Figure 3 and Figure 4This is the first embodiment of the present invention, which provides a novel device for producing low-hardness and low-height tire bead. This novel device for producing low-hardness and low-height tire bead includes a tire bead body 1 and an installation mechanism 2, as well as a processing mechanism 3 and an ejection mechanism 4. The installation mechanism 2 includes a rotating mounting block 202, and a sliding ring 205 is slidably installed on the outer side of the rotating mounting block 202. The processing mechanism 3 includes a discharge pipe head 301, an extrusion plate 303, a fixing frame 304, and a scraper 310. The discharge pipe head 301 is horizontally fixedly installed on one side of the inside of the device. An extrusion roller 307 is rotatably installed on the inner side of the fixing frame 304. The scraper 310 is movably installed on one side of the fixing block 309 through a telescopic rod 311.

[0020] The lower drive of the rotating mounting block 202 is mounted on the output end of the first motor 201.

[0021] A fixing plate 203 is fixedly installed on the lower outer side of the rotating mounting block 202, and a first electric push rod 204 is fixedly installed on the upper surface of the fixing plate 203.

[0022] The sliding ring 205 is fixedly installed at the output end of the first electric push rod 204.

[0023] The tire bead body 1 is installed on the upper outer side of the rotating mounting block 202.

[0024] The extrusion plate 303 is fixedly installed on the telescopic end of the second electric push rod 302, which is fixedly installed on the inner side of the equipment. The extrusion plate 303 is used to press the tire bead tightly against the surface of the rotating mounting block 202 to prevent displacement during tire bead processing.

[0025] A second motor 305 is fixedly installed on the inner side of the fixed frame 304. A drive gear 306 is driven and installed at the output end of the second motor 305. A toothed block 308 is fixedly installed at one end of the extrusion roller 307. The extrusion roller 307 meshes with the drive gear 306 through the toothed block 308.

[0026] A spring structure 312 is installed on the surface of the telescopic rod 311.

[0027] During operation, the first motor 201 drives the rotating mounting block 202 to rotate, while the first electric push rod 204 shortens, causing the sliding ring 205 to move downwards. After the rotating mounting block 202 loses its compression, it expands outwards, increasing its inner diameter to achieve internal support and fixation of the tire bead body 1. Subsequently, the second electric push rod 302 extends to push the extrusion plate 303, pressing the tire bead body 1 tightly against the surface of the rotating mounting block 202 to ensure processing stability. During processing, the second motor 305 drives the extrusion roller 307 to rotate via the drive gear 306, evenly extruding the triangular rubber onto the surface of the tire bead body 1. Simultaneously, the spring structure 312, in conjunction with the telescopic rod 311, keeps the scraper 310 pressed tightly against the outer side of the tire bead, automatically scraping away excess rubber.

[0028] Example 2

[0029] Reference Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the ejection mechanism 4 includes a top block 402 fixedly installed inside the sliding ring 205, and the rotating mounting blocks 202 are provided in several groups, with top grooves 401 opened between the several groups of rotating mounting blocks 202.

[0030] During operation, the first electric push rod 204 shortens, causing the sliding ring 205 to move downwards, releasing the pressure on the rotating mounting block 202. This allows multiple sets of rotating mounting blocks 202 to expand outwards, increasing their inner diameter to achieve internal support fixation of the tire bead body 1. Subsequently, the second electric push rod 302 extends, pushing the extrusion plate 303 to press the tire bead body 1 tightly against the surface of the rotating mounting block 202, ensuring processing stability. During processing, the second motor 305 drives the extrusion roller 307 to rotate via the drive gear 306, evenly extruding the triangular rubber onto the surface of the tire bead body 1. Simultaneously, the spring structure 312, in conjunction with the telescopic rod 311, keeps the scraper 310 close to the outside of the tire bead, automatically scraping away excess rubber. After processing, the first electric push rod 204 extends, pushing the sliding ring 205 upwards, pressing the rotating mounting block 202 inwards to reduce its inner diameter and decrease the fixing force on the tire bead body 1. At the same time, the sliding ring 205 drives the top block 402 to move upwards along the top groove 401, ejecting the finished tire bead body 1 for automatic unloading. The entire process ensures processing stability through the precise coordination of the internal support fixing and the ejection mechanism 4, while also achieving automated loading and unloading, which greatly improves production efficiency.

[0031] The remaining structure is the same as that in Example 1.

[0032] Based on embodiments 1-2, the working principle of this utility model is as follows: At the start of the process, the first electric push rod 204 shortens, causing the sliding ring 205 to move downward, releasing the compression on the multiple sets of rotating mounting blocks 202, causing the rotating mounting blocks 202 to expand outward and increase their inner diameter to achieve internal support fixation of the tire bead body 1. Subsequently, the first motor 201 drives the rotating mounting blocks 202 to rotate, while the second electric push rod 302 extends to push the extrusion plate 303, pressing the tire bead body 1 tightly against the surface of the rotating mounting blocks 202 to ensure processing stability. During processing, the second motor 305 drives the extrusion roller 307 to rotate through the drive gear 306, uniformly extruding the triangular rubber onto the surface of the tire bead body 1. At the same time, the spring structure 312, in conjunction with the telescopic rod 311, keeps the scraper 310 close to the outside of the tire bead, automatically scraping off excess rubber. After processing, the first electric push rod 204 extends and pushes the sliding ring 205 upward, squeezing the rotating mounting block 202 inward to reduce its inner diameter and decrease the fixing force on the tire bead body 1. At the same time, the sliding ring 205 drives the top block 402 to move upward along the top groove 401, ejecting the finished tire bead body 1 to achieve automatic unloading. The entire process, through the synergistic effect of internal support fixing, horizontal feeding, precision extrusion, and automatic ejection, solves the problem of low-hardness triangular rubber collapsing, ensuring continuous and stable production of high-comfort tires, while also achieving automated loading and unloading, significantly improving production efficiency.
