Description

Technical Field

[0001] This invention relates to tire production equipment, and more specifically, to a cord fabric splicing device and a tire production system. Background Technology

[0002] In the tire manufacturing process, in order to improve the tire's internal pressure-bearing capacity, a certain length of fiber cord needs to be added inside the tire. However, the cord can only be produced in a certain width. When in use, the cord needs to be cut and then spliced ​​together along the cord direction. The splicing process is called cord joint.

[0003] Conventional fiber curtain splicing devices integrate the splicing assembly and the retraction edge assembly into a single unit. The splicing device typically includes a splicing pressure plate, a material head baffle, and a retraction plate. During splicing, the fabric is joined through feeding, pressing, and unloading actions. The specific workflow is as follows: the splicing pressure plate and material head baffle are raised, the tail of the previous piece of fabric is retracted and pressed against the tail baffle, the material head baffle is lowered, the feeding conveyor belt feeds the next piece of fabric, the head of the next piece of fabric is pressed against the head baffle, the splicing pressure plate is lowered, and the tail of the previous piece of fabric and the head of the next piece of fabric are pressed together. In other words, existing fiber curtain splicing devices mostly use a pressing-type splicing method, where two pieces of fabric are bonded together with a certain overlap under the pressure of the splicing pressure plate. However, due to the varying viscosities and thicknesses of the fabrics, existing fiber curtain splicing devices are prone to problems such as material squeezing, material adhesion, and incomplete splicing during the pressing process, seriously affecting splicing efficiency and quality.

[0004] Therefore, the existing technology has the problem of poor performance of the fabric splice device. Summary of the Invention

[0005] The main objective of this invention is to provide a cord fabric splicing device and a tire production system to solve the problem of poor performance of cord fabric splicing devices in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, a fabric splicing device is provided, comprising: a splicing frame assembly; a splicing pressure plate; a material head baffle, at least a portion of the material head baffle and at least a portion of the splicing pressure plate having a mutually cooperating first guide structure, and the splicing pressure plate and the material head baffle being able to move relative to each other along the first guide structure; and a material tail baffle, the material tail baffle being disposed on the side of the splicing pressure plate away from the material head baffle; the splicing pressure plate, the material head baffle, and the material tail baffle are respectively connected to the splicing frame assembly and are able to move relative to the splicing frame assembly in a vertical direction.

[0007] Furthermore, the first guide structure is a toothed surface disposed on the side where the joint pressure plate and the material head baffle are close to each other, and the toothed surface of the joint pressure plate and the toothed surface of the material head baffle mesh with each other.

[0008] Furthermore, the first guide structure includes multiple guide protrusions and multiple guide grooves, all of which extend vertically and are spaced apart horizontally. One of the joint pressure plate and the material head baffle has a guide protrusion, and the other has a guide groove.

[0009] Furthermore, the fabric splicing device also includes: a first drive assembly, which is mounted on the conveyor belt assembly and drivenly connected to the splice pressure plate; a second drive assembly, which is mounted on the splice frame assembly and drivenly connected to the head baffle, and the head baffle is connected to the splice frame assembly through the second drive assembly; and a third drive assembly, which is mounted on the splice frame assembly and drivenly connected to the tail baffle, and the tail baffle is connected to the splice frame assembly through the third drive assembly.

[0010] Furthermore, the second drive assembly is disposed at the top of the connector frame assembly; and / or the third drive assembly is disposed at the bottom of the connector frame assembly.

[0011] Furthermore, the fabric splicing device also includes: a first guide member disposed on the splicing pressure plate, and the splicing frame assembly having a first guide rail that mates with the first guide member; and / or a second guide member disposed on the top of the material head baffle, and the splicing pressure plate having a second guide rail that mates with the second guide member.

[0012] Furthermore, at least one of the joint pressure plate, the head baffle, and the tail baffle has an anti-sticking layer on its surface.

[0013] Furthermore, the fabric splice device also includes a splice pad, which is disposed below the splice pressure plate. The splice pressure plate can move in a direction that is close to or away from the splice pad, and the thickness direction of the splice pressure plate and the thickness direction of the splice pad are perpendicular to each other.

[0014] According to another aspect of the present invention, a tire production system is provided, including the aforementioned cord splice device.

[0015] Furthermore, the tire production system also includes: a conveyor belt assembly, with the cord splice device located at one end of the conveyor belt assembly; and a return sidewall assembly located between the conveyor belt assembly and the cord splice device, and the return sidewall assembly being movable relative to the cord splice device.

[0016] Applying the technical solution of this invention, the fabric splicing device in this application includes a splicing frame assembly, a splicing pressure plate, a material head baffle, and a material tail baffle. At least a portion of the material head baffle and at least a portion of the splicing pressure plate have a mutually cooperating first guide structure, and the splicing pressure plate and the material head baffle can move relative to each other along the first guide structure; the material tail baffle is disposed on the side of the splicing pressure plate away from the material head baffle; the splicing pressure plate, the material head baffle, and the material tail baffle are respectively connected to the splicing frame assembly and can move relative to the splicing frame assembly in the vertical direction.

[0017] When using the cord fabric splicing device of this application, the position of the cord fabric splice can be precisely controlled through the cooperation of the splice pressure plate, the material head baffle, and the material tail baffle, improving the accuracy and stability of the cord fabric splice. Simultaneously, the first guide structure allows the splice pressure plate and the material head baffle to move relative to each other, thereby achieving efficient and precise splicing of the cord fabric, significantly improving production efficiency and product quality. Applying the cord fabric splicing device of this application to a tire production system can further optimize the production process, reduce the scrap rate during production, lower production costs, and improve the economic benefits of the enterprise. Furthermore, because the material head baffle and the splice pressure plate have a mutually cooperating first guide structure, the cord fabric will not be squeezed between the splice pressure plate and the material head baffle during the lifting or lowering of the material head baffle or the splice pressure plate, thereby reducing failure points and improving splice quality and efficiency. Therefore, the cord fabric splicing device of this application effectively solves the problem of poor performance in existing cord fabric splicing devices. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0029] To address the poor performance of existing cord fabric splicing devices, this application provides a cord fabric splicing device and a tire production system.

[0030] like Figures 1 to 5 As shown, the fabric splicing device in this application includes a splice frame assembly 10, a splice pressure plate 20, a material head baffle 30, and a material tail baffle 50. At least a portion of the material head baffle 30 and at least a portion of the splice pressure plate 20 have a mutually cooperating first guide structure 40, and the splice pressure plate 20 and the material head baffle 30 can move relative to each other along the first guide structure 40; the material tail baffle 50 is disposed on the side of the splice pressure plate 20 away from the material head baffle 30; the splice pressure plate 20, the material head baffle 30, and the material tail baffle 50 are respectively connected to the splice frame assembly 10 and can move relative to the splice frame assembly 10 in the vertical direction.

[0031] When using the cord fabric splicing device of this application, the position of the cord fabric splice can be precisely controlled through the cooperation of the splice pressure plate 20, the material head baffle 30, and the material tail baffle 50, improving the accuracy and stability of the cord fabric splice. Simultaneously, the first guide structure 40 allows the splice pressure plate 20 and the material head baffle 30 to move relative to each other, thereby achieving efficient and precise splicing of the cord fabric, significantly improving production efficiency and product quality. Applying the cord fabric splicing device of this application to a tire production system can further optimize the production process, reduce the scrap rate during production, lower production costs, and improve the economic benefits of the enterprise. Furthermore, because the material head baffle 30 and the splice pressure plate 20 have a mutually cooperating first guide structure 40, the cord fabric will not be squeezed between the splice pressure plate 20 and the material head baffle 30 during the lifting or lowering of the material head baffle 30 or the splice pressure plate 20, thereby reducing failure points and improving splice quality and efficiency. Therefore, the cord fabric splicing device of this application effectively solves the problem of poor performance in existing cord fabric splicing devices.

[0032] In one embodiment of this application, the first guide structure 40 is a toothed surface disposed on the side of the joint pressure plate 20 and the material head baffle 30 that are close to each other. The toothed surfaces of the joint pressure plate 20 and the material head baffle 30 mesh with each other. Furthermore, the guiding effect of the toothed surface makes the mating of the cord fabric joint more precise, reducing the displacement of the cord fabric during the mating process. This is suitable for cord fabric mating operations with high precision requirements, such as the production of tires for high-speed vehicles. The design of the toothed surface ensures the precise position of the cord fabric during mating, avoiding misalignment of the cord fabric due to minor deviations. Especially in the production of high-speed vehicle tires, this high-precision joint is key to ensuring the stability of the tire at high speeds and has a significant effect on improving the overall performance of the tire.

[0033] In one embodiment of this application, the first guide structure 40 includes multiple guide protrusions and multiple guide grooves. The multiple guide protrusions and multiple guide grooves extend vertically and are spaced apart horizontally. One of the joint pressure plate 20 and the material head baffle 30 has a guide protrusion, and the other has a guide groove. This guide structure can more effectively control the mating position of the cord fabric joint, improve joint quality, and is suitable for highly automated tire production lines, significantly improving production efficiency. Through the cooperation of the guide protrusions and guide grooves, not only is the positioning accuracy of the cord fabric joint improved, but also fast and accurate cord fabric joint operation can be achieved on automated production lines.

[0034] Both of the above embodiments can effectively prevent the fabric from being squeezed between the joint pressure plate 20 and the material head baffle 30 during the lifting or lowering of the material head baffle 30 or the joint pressure plate 20, thereby reducing failure points and improving joint quality and efficiency. Of course, in this application, the first guide structure 40 can also be configured into other shapes according to actual usage requirements.

[0035] Optionally, the fabric splicing device further includes a first drive assembly 60, a second drive assembly 70, and a third drive assembly 80. The first drive assembly 60 is mounted on the conveyor belt assembly 300 and drivenly connected to the splice pressure plate 20; the second drive assembly 70 is mounted on the splice frame assembly 10 and drivenly connected to the head baffle 30, with the head baffle 30 connected to the splice frame assembly 10 via the second drive assembly 70; the third drive assembly 80 is mounted on the splice frame assembly 10 and drivenly connected to the tail baffle 50, with the tail baffle 50 connected to the splice frame assembly 10 via the third drive assembly 80. By setting the first drive assembly 60, the second drive assembly 70, and the third drive assembly 80, automated control of the splice pressure plate 20, the head baffle 30, and the tail baffle 50 can be achieved, improving production efficiency. This is suitable for large-scale tire production plants and can significantly improve the automation level of the production line. The introduction of automated control makes the operation of the fabric splicing device more precise and efficient. Furthermore, in this application, the first drive assembly 60, the second drive assembly 70, and the third drive assembly 80 can be composed of multiple drive cylinders. Preferably, the first drive assembly 60, the second drive assembly 70, and the third drive assembly 80 each have two drive cylinders. Simultaneously, different drive cylinders are connected to both ends of the connector pressure plate 20, the head baffle 30, and the tail baffle 50, respectively, thereby ensuring that the connector pressure plate 20, the head baffle 30, and the tail baffle 50 can move more stably in the vertical direction.

[0036] Optionally, the second drive assembly 70 is located at the top of the joint frame assembly 10. More optionally, the third drive assembly 80 is located at the bottom of the joint frame assembly 10. This layout facilitates the installation and maintenance of the drive assemblies, reduces the equipment's footprint, and is suitable for space-constrained tire production environments, such as small tire manufacturing plants or production line retrofit projects. Placing the drive assemblies at the top or bottom not only optimizes the equipment's spatial layout but also facilitates maintenance and inspection.

[0037] Optionally, the fabric splicing device further includes a first guide 90 and a second guide 100. The first guide 90 is disposed on the splicing pressure plate 20, and the splicing frame assembly 10 has a first guide rail that cooperates with the first guide 90. The second guide 100 is disposed on the top of the material head baffle 30, and the splicing pressure plate 20 has a second guide rail that cooperates with the second guide 100. By setting the first guide 90, the movement direction of the splicing pressure plate 20 can be effectively restricted, thereby ensuring the pressing effect of the splicing pressure plate 20 on the fabric. By setting the second guide 100, it is possible to further ensure that the splicing pressure plate 20 and the material head baffle 30 can move along the first guide structure 40, thereby reducing the movement resistance between the splicing pressure plate 20 and the material head baffle 30.

[0038] Optionally, at least one of the joint pressure plate 20, the head baffle 30, and the tail baffle 50 has an anti-sticking layer on its surface. Alternatively, in this application, the joint pressure plate 20, the head baffle 30, and the tail baffle 50 are each treated with an anti-sticking process, thereby further reducing the problem of material sticking when the joint pressure plate 20 and the head baffle 30 are lifted, and improving the joint quality. Simultaneously, the tail baffle 50, with its anti-sticking treatment, can reduce contact resistance with the fabric, preventing incomplete feeding due to excessive resistance.

[0039] Optionally, the cord fabric splice device further includes a splice pad 200, which is disposed below the splice pressure plate 20. The splice pressure plate 20 is movable in a direction approaching or away from the splice pad 200, and the thickness direction of the splice pressure plate 20 is perpendicular to the thickness direction of the splice pad 200. The splice pad 200 provides a flat support surface for the cord fabric splice, which helps to improve the flatness and strength of the splice, and is suitable for tire production where high flatness of the cord fabric splice is required.

[0040] like Figure 5 As shown, this application also provides a tire production system, including the aforementioned cord splice device. The tire production system further includes: a conveyor belt assembly 300, with the cord splice device located at one end of the conveyor belt assembly 300; and a retractable sidewall assembly 400, located between the conveyor belt assembly 300 and the cord splice device, and capable of moving relative to the cord splice device. Furthermore, in this application, the cord splice device and the retractable sidewall assembly 400 are respectively fixed to the conveyor belt assembly 300. The retractable sidewall assembly 400 is not connected to the splice assembly. The significant inertia of the retractable sidewall assembly 400 during retraction has no impact on the crimping process of the cord splice device, effectively reducing frame swaying caused by the significant inertia of the retractable sidewall assembly 400 during retraction and improving the stability of the splice quality.

[0041] When using the tire production system of this application, during the pressing process of the cord fabric, after the previous piece of material is spliced, the joint pressure plate 20 and the material head baffle 30 are raised simultaneously. The conveyor belt assembly 300 moves the spliced ​​cord fabric forward to unload the material. Then, the material tail baffle 50 is raised, and the retracting edge assembly 400 moves the material tail of the cord fabric towards the cord fabric joint device so that the material tail abuts against the material tail baffle 50. Then, the material head baffle 30 falls and gently presses on the cord fabric. The feeding conveyor belt feeds the next piece of material to the material tail baffle 50 so that the material head of the cord fabric abuts against the material head baffle 30 under inertial motion. Then, the joint pressure plate 20 falls and presses the material tail of the previous piece of material together with the material head of the next piece of material. Then, the conveyor belt assembly 300 moves the spliced ​​cord fabric forward to unload the material and repeats the above actions.

[0042] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0043] 1. Effectively solves the problem of poor performance of existing fabric splice devices;

[0044] 2. Simple structure and stable performance.
