Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and more specifically, to a guide device and a tire production system. Background Technology

[0002] The thinness of the underside tread compound in engineering tires makes it prone to tearing and deformation during the separation process, thus damaging the compound. Therefore, improving the separation effect of the underside tread compound in engineering tires has always been a difficult problem to solve at the separation station. Furthermore, current technologies generally rely on manual assistance for separation, which is prone to deviations during material feeding, affecting the separation effect of the compound.

[0003] Therefore, the existing technology suffers from poor separation effect of the rubber compound in the tread of engineering tires. Utility Model Content

[0004] The main purpose of this invention is to provide a guide device and a tire production system to solve the problem of poor guide effect of the tread rubber material in engineering tires in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a guide device is provided, comprising: a mounting frame; a first roller rotatably mounted on the mounting frame; at least two second rollers rotatably mounted on the mounting frame, all the second rollers being spaced apart circumferentially from the first roller, each second roller having a material passage gap with the first roller, and the diameter of the second roller being smaller than the diameter of the first roller; and a pressure roller assembly movably mounted on the mounting frame and capable of moving towards or away from the first roller, wherein the pressure roller assembly is located downstream of the second roller in the rotation direction of the first roller.

[0006] Furthermore, the axes of the first roller and the second roller are parallel to each other; and / or the material clearance is greater than or equal to 25 mm.

[0007] Furthermore, there are two second rollers, and the angle between the line connecting the axis of the two second rollers and the axis of the first roller is greater than or equal to 80 degrees and less than or equal to 100 degrees.

[0008] Furthermore, the guide device also includes a transmission assembly, through which the first roller is driven to at least one second roller.

[0009] Furthermore, the first and second rollers are of the same length.

[0010] Furthermore, the mounting bracket includes: a body portion; at least two oppositely arranged mounting arms, the mounting arms being disposed on the body portion, and the two ends of the first roller and the two ends of the second roller being respectively connected to the two mounting arms.

[0011] Furthermore, the guide device also includes a drive assembly, which is mounted on one of the mounting arms and connected to the first roller drive.

[0012] Furthermore, the pressure roller assembly includes: a drive unit, which is mounted on a mounting frame; a transmission unit; and a pressure roller body, wherein the drive unit is drivenly connected to the pressure roller body via the transmission unit.

[0013] Furthermore, the transmission unit includes: a transmission rod, a driving unit drivingly connected to one end of the transmission rod, and the axis of the transmission rod being parallel to the axis of the first roller; at least two parallel transmission arms, the two transmission arms being spaced apart along the axial direction of the transmission rod and respectively connected to both ends of the pressure roller body.

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

[0015] Applying the technical solution of this utility model, the guiding device in this application includes a mounting frame, a first roller, at least two second rollers, and a pressure roller assembly. The first roller is rotatably mounted on the mounting frame; the second rollers are rotatably mounted on the mounting frame, all the second rollers are spaced apart circumferentially along the first roller, each second roller has a material passage gap with the first roller, and the diameter of the second roller is smaller than the diameter of the first roller; the pressure roller assembly is movably mounted on the mounting frame and can move in a direction close to or away from the first roller, and in the rotation direction of the first roller, the pressure roller assembly is located downstream of the second roller.

[0016] When using the guiding device of this application, the lower tread rubber material can be guided onto the guiding device by a conveyor trolley carrying the fabric. During the guiding process, the rubber sheet of the lower tread rubber material passes sequentially through the material passage gap formed by different second rollers and the first roller and contacts the first roller. Since there are at least two second rollers in this application, this arrangement can effectively increase the wrap angle between the lower tread rubber material and the first roller, thereby increasing the contact area between the lower tread rubber material and the first roller. Furthermore, since the guiding device also has a pressure roller assembly that can move towards or away from the first roller, the lower tread rubber material can be clamped by the cooperation between the pressure roller assembly and the first roller, thereby increasing the friction between the first roller and the lower tread rubber material, thus improving the guiding effect of the lower tread rubber material, improving the feeding accuracy of the lower tread, and thus protecting the lower tread rubber material and preventing its deformation. Therefore, the guiding device of this application effectively solves the problem of poor guiding effect of the lower tread rubber material in the prior art. Attached Figure Description

[0023] 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.

[0024] In this utility model, 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 used to limit this utility model.

[0025] To address the problem of poor separation effect of the tread rubber compound in existing engineering tires, this application provides a separation device and a tire production system.

[0026] Furthermore, the tire production system in this application has the following guide opening device.

[0027] like Figure 1 and Figure 2As shown, the guide device in this application includes a mounting frame 10, a first roller 20, at least two second rollers 30, and a pressure roller assembly 40. The first roller 20 is rotatably mounted on the mounting frame 10; the second rollers 30 are rotatably mounted on the mounting frame 10, and all the second rollers 30 are spaced apart circumferentially along the first roller 20. Each second roller 30 has a material passage gap with the first roller 20, and the diameter of the second roller 30 is smaller than the diameter of the first roller 20; the pressure roller assembly 40 is movably mounted on the mounting frame 10 and can move in a direction close to or away from the first roller 20. In the rotation direction of the first roller 20, the pressure roller assembly 40 is located downstream of the second roller 30.

[0028] When using the guiding device of this application, the lower tread rubber material can be guided onto the guiding device by a conveyor trolley carrying the fabric. During the guiding process, the rubber sheet of the lower tread rubber material passes sequentially through the material passage gap formed by different second rollers 30 and the first roller 20 and comes into contact with the first roller 20. Since there are at least two second rollers 30 in this application, this arrangement can effectively increase the wrap angle between the lower tread rubber material and the first roller 20, thereby increasing the contact area between the lower tread rubber material and the first roller 20. Furthermore, since the guiding device also has a pressure roller assembly 40 that can move towards or away from the first roller 20, the lower tread rubber material can be clamped by the cooperation between the pressure roller assembly 40 and the first roller 20, thereby increasing the friction between the first roller 20 and the lower tread rubber material, thus improving the guiding effect of the lower tread rubber material, improving the feeding accuracy of the lower tread, and thus protecting the lower tread rubber material and preventing its deformation. Therefore, the guiding device of this application effectively solves the problem of poor guiding effect of the lower tread rubber material in the prior art.

[0029] Optionally, the axes of the first roller 20 and the second roller 30 are parallel to each other. The material clearance is greater than or equal to 25 mm. The parallel axes ensure uniform distribution of the rubber compound, while the larger material clearance prevents the rubber compound from being excessively compressed during the distribution process. This is crucial for maintaining the original structure and properties of the rubber compound, especially when producing high-performance engineering tires.

[0030] In one specific embodiment of this application, there are two second rollers 30, and the angle between the line connecting the axis of the two second rollers 30 and the axis of the first roller 20 is greater than or equal to 80 degrees and less than or equal to 100 degrees. This angle design maximizes the contact length between the adhesive and the first roller 20, thereby increasing the friction during the separation process and ensuring stable and continuous separation of the adhesive. Of course, in this application, the relative position between the first roller 20 and the second roller 30 can be adaptively adjusted according to actual usage.

[0031] Optionally, the guide device further includes a transmission assembly, through which the first roller 20 is driven to at least one second roller 30. The introduction of the transmission assembly enables the first roller 20 and the second roller 30 to rotate synchronously, avoiding twisting and damage to the rubber material during the guide process, which has a significant effect on maintaining the flatness and consistency of the rubber material.

[0032] Optionally, the first roller 20 and the second roller 30 are of the same length. This identical length ensures uniform handling of the rubber compound during the guiding process, avoiding localized overstretching or compression, which is crucial for maintaining the overall quality and performance of the rubber compound.

[0033] In one specific embodiment of this application, the mounting frame 10 includes a body portion 11 and at least two oppositely arranged mounting arms 12. The mounting arms 12 are disposed on the body portion 11, and the two ends of the first roller 20 and the two ends of the second roller 30 are respectively connected to the two mounting arms 12. This structural design makes the guide device more stable, able to withstand the pressure of high-speed guide and heavy-load rubber material, and suitable for large-scale, continuous engineering tire production environments.

[0034] Optionally, the guide opening device further includes a drive assembly 50, which is mounted on one of the mounting arms 12 and drivenly connected to the first roller 20. The drive assembly 50 makes the rotation of the first roller 20 more precise and controllable, thereby ensuring the performance of the guide opening device.

[0035] Specifically, the pressure roller assembly 40 includes a drive unit 41, a transmission unit 42, and a pressure roller body 43. The drive unit 41 is mounted on the mounting frame 10; the drive unit 41 is drivenly connected to the pressure roller body 43 via the transmission unit 42. More specifically, the transmission unit 42 includes: a transmission rod 421, with the drive unit 41 drivenly connected to one end of the transmission rod 421, and the axis of the transmission rod 421 being parallel to the axis of the first roller 20; at least two parallel transmission arms 422, which are spaced apart along the axial direction of the transmission rod 421 and respectively connected to both ends of the pressure roller body 43. This design makes the adjustment of the pressure roller assembly 40 more flexible, allowing for real-time adjustment based on the thickness and hardness of the rubber compound, ensuring the stability and consistency of the rubber compound during the opening process, and is suitable for the production of various specifications and types of engineering tires.

[0036] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0037] 1. Effectively solves the problem of poor separation effect of the tread rubber material in existing engineering tires;

[0038] 2. Simple structure and stable performance.
