[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 described in the background technology, tires used for engineering vehicles are referred to as engineering tires, and engineering tires with specifications of more than 49 inches are generally referred to as giant tires. In the process of preparing giant tires, a carcass tube needs to be prepared. The carcass tube is made of various rubber materials such as steel cords and rubber sheets wound on a carcass drum and pressed together by a carcass rolling device. The existing giant tire carcass rolling device is generally enlarged on the basis of a conventional engineering tire carcass rolling device, and includes a pair 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. The width of the giant tire carcass tube is much larger than that of the conventional carcass tube, which can reach 3000mm for 49 inches and 4800mm for 63 inches, while the rotation speed of the carcass drum is relatively low, which limits the increase in the speed of the existing carcass rolling device in the width direction, making the carcass tube rolling process time-consuming and inefficient, affecting the production efficiency of the tire.

[0025] See also Figures 1 to 3As shown, in order to solve the above-mentioned problem, an embodiment of the present invention provides a tire carcass auxiliary rolling device, including a first frame 10, a swing frame 20 and a pressure roller mechanism 30, the bottom of the swing frame 20 is rotatably mounted on the first frame 10, the pressure roller mechanism 30 is mounted on the swing frame 20, and the pressure roller mechanism 30 includes a shaft 32 and a plurality of pressure rollers 31 sleeved on the shaft 32. During operation, the pressure roller mechanism is swung to the position corresponding to the tire body to be rolled by the swing frame 20, so that multiple pressure rollers are in contact with the outer wall of the tire body to be rolled, and the surface of the tire body to be rolled is rolled by multiple pressure rollers together, and the widths of at least two pressure rollers are different, so that the rubber materials at different parts of the tire tube can be pre-pressed synchronously with pressure rollers of different widths and materials, so that each layer fits tightly, and the quality of tire tube preparation is improved. If the width of the rubber strip is narrow, it is rolled by a narrower pressure roller, specifically, the width of the rubber strip does not exceed the width of a single pressure roller, and the rolling effect is better (no bubbles exist), and there is no need to roll separately again later, thereby reducing the total rolling time and improving the efficiency of tire tube preparation. Among them, the first frame is welded by steel sections.

[0026] In order to realize the driving of the swing frame, the tire carcass auxiliary rolling device of this embodiment also includes a second frame 40 and a swing driving device. The second frame 40 is arranged on the side of the first frame 10 away from the tire carcass to be rolled; the swing driving device is installed on the second frame 40, and the output end of the swing driving device is pivotally connected to the end of the roller mechanism 30 away from the tire carcass to be rolled, so as to drive the swing frame 20 to swing. The swing driving device of this embodiment includes a first cylinder 41, which is installed on the second frame 40, and the output end of the first cylinder 41 is pivotally connected to the end of the roller mechanism 30 away from the tire carcass to be rolled. The swing frame is welded by steel. The lower side of the swing frame is connected to the bearing seat on the first frame through the swing shaft; the first cylinder is installed on the swing cylinder mounting seat of the second frame, and the front end is connected to the swing frame, which can push the swing frame to swing along the swing shaft, thereby realizing the lifting and falling of the pressure roller. The output end of the first cylinder is arranged downward.

[0027] In order to adjust the distance between the pressure roller and the surface of the tire body to be rolled so that the pressure roller can effectively press on the surface of the tire body to be rolled, the tire carcass auxiliary rolling device of this embodiment includes a telescopic mechanism, which is installed on the swing frame 20. The telescopic mechanism includes a telescopic drive device and a track 51. The track 51 is installed at the bottom of the pressure roller mechanism 30. The track 51 extends along the telescopic direction of the telescopic drive device. The telescopic drive device is installed on the swing frame 20. The pressure roller mechanism 30 is movably connected to the swing frame 20 through the track 51. When working, the telescopic drive device drives the pressure roller mechanism to move forward and backward along the track direction to adjust the distance between the pressure roller and the surface of the tire body to be rolled.

[0028] Specifically, the telescopic driving device of this embodiment includes a second cylinder 50, which is mounted on the swing frame 20, and the output end of the second cylinder 50 is drivingly connected to the pressure roller mechanism 30. The first cylinder and the second cylinder of this embodiment can also be replaced by a driving device such as a hydraulic cylinder, a screw motor, etc., as long as the driving device can achieve the expected driving effect.

[0029] The compression roller mechanism 30 of this embodiment includes a main body 34, a shaft body 32 is mounted on the main body 34, a track 51 is arranged at the bottom of the main body 34, a slider 52 is arranged on the top of the swing frame 20, and the slider 52 is movably mounted on the track 51. The compression mechanism is welded by steel sections, connected to the swing frame through the slider 52, and the movement of the compression roller mechanism can be made smoother through the cooperation of the slider and the track.

[0030] The pressure roller 31 of this embodiment includes a roller core 311, a roller cover 322 sleeved on the outside of the roller core 311, and an intermediate filler 323 arranged between the roller core 311 and the roller cover 322. The roller core 311 is rotatably sleeved on the shaft body 32. The typical material of the roller cover 322 is polyurethane, and the typical material of the intermediate filler is sponge rubber. The roller cover material has a high hardness and plays a role in protecting the intermediate filler. The intermediate filler has a low hardness and deforms under pressure to ensure that the pressure roller is close to the surface of the tire tube to be rolled; the typical material of the roller core is wear-resistant steel to ensure that the roller can move along the roller shaft; all the pressure rollers are connected in series, supported by the shaft body in the middle, the inner diameter of the pressure roller is larger than the outer diameter of the shaft body, and a certain gap is left between the two to ensure that each pressure roller can move in the radial direction. Preferably, the width of the pressure roller 31 located in the middle area of ​​the shaft body 32 of this embodiment is larger than the width of the pressure roller 31 located at the two end areas of the shaft body 32, and the width of all the pressure rollers is determined according to the production process requirements. Usually the middle part needs to be rolled with wider and smoother rubber, so the required rollers are wide and fewer in number. The rubber on both sides is narrow and uneven, so the required rollers are narrow and more in number.

[0031] In order to prevent the pressure roller from moving axially, the pressure roller mechanism 30 of this embodiment further includes two limiting clamps 33, which are respectively installed on both sides of the shaft body 32. In the axial direction, the limiting clamps 33 limit the axial movement of the pressure roller.

[0032] The swing frame 20 of this embodiment is provided with a mounting plate 60, and the second cylinder 50 is mounted on the mounting plate 60. The tire carcass auxiliary rolling device also includes a limit screw 61, which is screwed on the mounting plate 60, and the axial direction of the limit screw 61 is parallel to the axial direction of the second cylinder 50. The limit screw is used to adjust and limit the moving distance of the telescopic mechanism in the track direction. The limit screw is fixed on the frame, is rigid, and has a large vibration when impacted. In other embodiments, the limit screw can be added with a buffer component composed of a polyurethane block or an oil pressure buffer component to make it have a telescopic function, so as to reduce the impact vibration when the movement stops.

[0033] The working process of this embodiment is as follows: initially, the first cylinder is in the extended position, so that the entire swing frame swings upward at a certain angle, so that the pressure roller mechanism swings upward obliquely; the second cylinder extends, so that the entire pressure roller mechanism extends above the carcass drum; and the first cylinder retracts, so that the entire swing frame swings downward at a certain angle, and the second cylinder and multiple pressure rollers fall obliquely downward and approach the rubber on the carcass drum; the carcass drum rotates, and multiple pressure rollers are driven by the rotation of the carcass drum to achieve rolling of the rubber; after the rubber rolling of all areas is completed, the first cylinder extends, so that the entire swing frame swings upward at a certain angle, the pressure roller mechanism swings upward obliquely and separates from the carcass tube, and the second cylinder retracts to complete the reset. In other embodiments of the present invention, the track can also be replaced by a guide rod, and the slider can replace the guide sleeve structure.

[0034] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0035] The pressure roller mechanism is swung to a position corresponding to the tire body to be rolled by the swing frame, so that multiple pressure rollers are in contact with the outer wall of the tire body to be rolled, and the surface of the tire body to be rolled is rolled together by multiple pressure rollers. The widths of at least two pressure rollers are different, so that rubber materials at different parts of the tire body tube can be pre-pressed synchronously with pressure rollers of different widths and materials, so that each layer fits tightly, the quality of tire body tube preparation is improved, and some rubber strips do not need to be rolled separately again later, thereby reducing the total rolling time and improving the efficiency of tire body tube preparation.
