[0002] Tires used for engineering vehicles are referred to as engineering tires. Engineering tires with specifications of 49 inches or more are usually called giant tires. In the process of preparing giant tires, a carcass tube must be prepared. The carcass tube is made of steel cords, rubber sheets and other rubber materials wound on a carcass drum and pressed by a carcass rolling device.

[0003] The existing giant tire carcass rolling device is generally an enlarged design based on the conventional engineering tire carcass rolling device, which includes one or two pairs of rolling wheels of the same size and specifications, which are driven by a motor screw structure to move in the width direction, and according to a pre-set process action sequence, various rubber materials on the carcass tube are rolled and compacted.

[0004] In order to ensure the rolling quality and reduce the amount of gas trapped between the layers of rubber, the conventional carcass tube rolling device first compacts the entire middle carcass tube, and then compacts the carcass tube in the adjacent area.

In addition, the width of the roller cannot be increased indefinitely, resulting in a low speed of separation and combination in the width direction of the existing carcass rolling device, which makes the carcass tube rolling process time-consuming and inefficient, affecting the production efficiency of the tire.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] As mentioned in the background technology, the existing giant tire carcass rolling device is generally designed to be enlarged on the basis of the conventional engineering tire carcass rolling device, including one or two pairs of rolling wheels of the same size and specifications, which are driven by the motor screw structure to move in the width direction, and the various rubber materials on the carcass tube are rolled and compacted according to the pre-set process action sequence. In order to ensure the rolling quality and reduce the gas trapped between the layers of rubber materials, the conventional carcass tube rolling device first compacts the entire middle carcass tube, and then compacts the carcass tube in the adjacent area. The carcass tube rotates one circle and can only move a distance not exceeding the width of the pressure roller, and its moving speed is limited. The width of the giant tire carcass tube is much larger than that of the conventional carcass tube (49 inches can reach 3000mm, 63 inches can reach 4800mm), and the rotation speed of the carcass drum is relatively low. In addition, the width of the pressure roller cannot be increased without limit, resulting in a low speed of the existing carcass rolling device in the width direction, which makes the carcass tube rolling process time-consuming and inefficient, affecting the production efficiency of the tire.

[0025] To solve the above problems, see Figures 1 to 3As shown, an embodiment of the present invention provides a tire carcass laminating device. The tire carcass laminating device of this embodiment includes a frame 10, a telescopic driving device 20 and a laminating portion 30. The telescopic driving device 20 is installed on the frame 10; the laminating portion 30 is drivingly connected to the telescopic driving device 20, and the laminating portion 30 includes a plurality of laminating components 31. The laminating components 31 include laminating rollers 311. The axial directions of the plurality of laminating rollers 311 are all parallel to the axial direction of the carcass to be laminarized. The projections of the plurality of laminating rollers 311 on a plane parallel to the axial direction of the laminating rollers 311 jointly form a laminating area. The width of the laminating area is greater than the width of the carcass to be laminarized, wherein the width of the laminating area is the distance from the first laminating roller to the last laminating roller. During operation, multiple lamination rollers can roll the tire carcass together. The tire carcass lamination device of the present invention includes multiple lamination components, and the projections of multiple lamination rollers 311 on a plane parallel to the axial direction of the lamination roller 311 together form a lamination area. The width of the lamination area is greater than the width of the tire carcass to be laminated. Compared with the conventional carcass tube rolling device, while ensuring that the gas between the rubber materials can be discharged, multiple lamination rollers can be rolled synchronously with high efficiency, thereby reducing the total rolling time and improving the carcass tube preparation efficiency.

[0026] Specifically, the multiple pressing assemblies 31 in this embodiment are divided into a first roller group 32 and a second roller group 33. The axes of the multiple pressing rollers 311 of the first roller group 32 coincide with each other, and the axes of the multiple pressing rollers 311 of the second roller group 33 coincide with each other. A clearance gap is provided between the first roller group 32 and the second roller group 33. By providing the first roller group and the second roller group, it is possible to prevent multiple pressing assemblies in the same row from being too densely packed.

[0027] In order to more comprehensively press the tire body, the plane passing through the axes of the multiple pressing rollers 311 of the first roller group 32 and the axes of the multiple pressing rollers 311 of the second roller group 33 in this embodiment is the first plane, the plane perpendicular to the first plane and parallel to the axes of the pressing rollers 311 of the pressing assembly 31 is the second plane, and the projections of the multiple pressing rollers 311 of the first roller group 32 on the second plane are continuous with the projections of the multiple pressing rollers 311 of the second roller group 33 on the second plane, that is, the projections of the pressing rollers of the first roller group and the pressing rollers of the second roller group on the second plane have an overlapping area to ensure that when all the pressing assemblies are extended, the entire rolling width range can be covered.

[0028] The telescopic driving device 20 in this embodiment includes a driving cylinder 21 and a moving frame 22. The driving cylinder 21 is drivingly connected to the moving frame 22. The pressing part 30 is installed on the moving frame 22. The first roller set 32 ​​is installed at the upper end of the moving frame 22, and the second roller set 33 is installed at the lower end of the moving frame 22.

[0029] In this embodiment, a guide rail is provided on the frame 10, and a slider is provided at the bottom of the mobile frame 22, and the slider is movably mounted on the guide rail. The mobile frame is welded by section steel, and the bottom of the mobile frame is connected to the frame body by the slider. The telescopic drive device can also use a cylinder with a displacement sensor, or a screw assembly driven by a motor. The telescopic drive device can push the entire mobile frame forward and backward in the direction of the guide rail; the frame is welded by section steel and is used to support the entire device.

[0030] In order to facilitate the pressure on the tire body, the frame 10 in this embodiment includes a base and an inclined bracket. The inclined bracket is installed on the base. The extension direction of the upper end of the inclined bracket is set at a preset angle to the plane where the base is located. The guide rail is set at the upper end of the inclined bracket and extends along the extension direction of the upper end of the inclined bracket. The pressing part is supported in a direction close to the tire body by the inclined bracket.

[0031] The lamination rollers are composed of a roller surface, a roller core, and a lamination roller shaft. The roller surface is made of a softer material, such as rubber or polyurethane, the roller core is made of a hard material, such as steel, and the lamination roller shaft is a rigid shaft with bearings. In one embodiment, the axial lengths of the multiple lamination rollers 311 in this embodiment are all the same.

[0032] In another embodiment, the axial lengths of the multiple lamination rollers 311 in this embodiment are all different, or at least two are different. For the rubber materials in different parts of the tire body, lamination rollers of different widths and materials can be used and rolled at different pressures to make the layers fit tightly, thereby improving the quality of tire body tube preparation.

[0033] In order to realize the extension and retraction of the lamination assembly, the lamination assembly 31 in this embodiment includes a mounting frame 312 and a driving unit. The mounting frame 312 is installed on the movable frame 22, the driving unit is installed on the mounting frame 312, and the lamination roller 311 is installed at the output end of the driving unit. The driving unit is used to drive the lamination roller 311 to extend and retract. The lamination roller is driven by the extension and retraction of the driving unit, thereby realizing the extension and retraction of the lamination roller and ensuring the lamination force of the lamination roller.

[0034] Specifically, the driving part in this embodiment includes a driving cylinder 313 and a driving rod 314 drivingly connected to the output end of the driving cylinder 313, the pressing roller 311 is rotatably mounted on the end of the driving rod 314 away from the driving cylinder 313, and a protrusion 315 is provided on the mounting frame 312, and a guide hole is provided inside the protrusion 315, and the driving rod 314 is movably inserted into the guide hole. Among them, the protrusion is a mounting seat made of casting or welding, and the whole is a U-shaped structure. After the mounting seat is mounted on the mounting frame, the space between the U-shaped structure and the mounting frame forms a guide hole, and the bottom of the mounting seat is provided with a flange structure, the flange structure is close to the mounting frame, and the flange structure is fixedly connected to the mounting frame by a threaded fastener.

[0035] The specific working process is as follows: Initially, the telescopic drive device drives the mobile frame to extend, so that the entire mobile frame moves upward and approaches the tire body to be pressed. A pressing roller in the middle position of the first roller group extends, so that the pressing roller first contacts the rubber material. The pressing roller is driven by the rotation of the tire drum to roll the rubber material. When the tire drum rotates a certain angle or at intervals, the pressing roller of the second roller group with an overlapping rolling area with the extended pressing roller extends, contacts the rubber material, and rolls the adjacent area; when the tire drum rotates a certain angle or at intervals, the other pressing rollers with overlapping rolling areas on both sides of the first roller group extend, contact the rubber material, and roll the adjacent area, and this cycle continues until the entire tire body is rolled. The actions are carried out in sequence to achieve orderly rolling of the tire tube, and the air between the rubber materials of the tire tube is gradually discharged from the middle to the two sides. After the rolling of the entire tire tube is completed, all pressing components return synchronously; the mobile frame returns to its original position, and the rolling is completed.

[0036] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0037] The tire carcass pressing device of the present invention comprises a plurality of pressing assemblies, and the projections of the plurality of pressing rollers on a plane parallel to the axial direction of the pressing rollers together form a pressing area, the width of the pressing area is greater than the width of the tire carcass to be pressed, and compared with a conventional carcass tube rolling device, while ensuring that the gas between the rubber materials can be discharged, it can realize synchronous rolling of multiple pressing rollers with high efficiency, thereby reducing the total rolling time and improving the carcass tube preparation efficiency.
