DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0029] like Figure 1-5 As shown, the utility model provides a tire building drum device, comprising a control component 3, a plurality of active shoe components 1 and a plurality of driven shoe components 2.

[0030] refer to Figure 4 The control component 3 includes two sliding sleeves 33 and a driving component, and the driving component is used to control the relative movement or opposite movement of the two sliding sleeves 33.

[0031] refer to Figure 2 and Figure 4 The active tile assembly 1 includes a first main tile plate 13, two first auxiliary tiles 11, a first sliding rod 12 and a first connecting assembly; the first main tile plate 13 is arranged between the two first auxiliary tiles 11 and is slidably installed on the first sliding rod 12 respectively, and the first main tile plate 13 and the two first auxiliary tiles 11 are connected to the two sliding sleeves 33 through the first connecting assembly.

[0032] refer to Figure 3 The driven shoe assembly 2 includes a second main shoe plate 23, two second auxiliary shoe plates 21, a second slide rod 22 and a second connecting assembly. The second main shoe plate 23 is arranged between the two second auxiliary shoe plates 21 and is slidably mounted on the second slide rod 22 respectively.

[0033] refer to Figure 1 The active shoe assembly 1 and the driven shoe assembly 2 are spaced apart and arranged in an array on the same circumference and are connected to each other through a second connecting assembly, and the control assembly 3 is arranged in the middle of the array circumference.

[0034] In some possible embodiments, when the driving assembly controls the two sliding sleeves 33 to move relative to each other, the first connecting assembly drives the two first auxiliary tiles 11 to move away from the first main tile 13, that is, the two first auxiliary tiles 11 and the first main tile 13 are linearly slidably arranged on the first slide bar 12; at the same time, the second connecting assembly drives the adjacent second auxiliary tiles 21 to move away from the second main tile 23, that is, the two second auxiliary tiles 21 and the second main tile 23 are linearly slidably arranged on the second slide bar 22. While moving, the active tile assembly 1 and the driven tile assembly 2 move away from the control assembly, that is, expand outward, that is, the length and diameter of the tire building drum device are synchronously increased.

[0035] When the driving assembly controls the two sliding sleeves 33 to move in opposite directions, the first connecting assembly drives the two first auxiliary tiles 11 to move toward the first main tile 13; at the same time, the second connecting assembly drives the adjacent second auxiliary tile 21 to move toward the second main tile 23. While moving, the active tile assembly 1 and the driven tile assembly 2 move toward the control assembly, that is, they shrink and expand inward, thereby achieving a synchronous reduction in the length and diameter of the tire building drum device.

[0036] refer to Figure 4 and Figure 5 In a possible embodiment, the drive assembly includes a screw rod 35 and two screw sleeves 36 threadedly matched on the screw rod; the screw rod 35 and the screw sleeve 36 are arranged in a sleeve 34, and the screw sleeve 36 has a plurality of slide grooves 341 extending along the axial direction of the sleeve 34 in a circumferential array; two slide sleeves 33 are sleeved on the screw sleeve 36 and are respectively fixedly connected with the two screw sleeves 36; the screw rod 35 is provided with two sections of threads with opposite rotation directions, and the two screw sleeves 36 are respectively matched with the two sections of threads; a driving motor is connected to the connecting shaft 31 at one end of the screw rod 35. That is to say, when the driving motor controls the screw rod 35 to rotate, it can drive the two screw sleeves 36 to move relative to each other or move in opposite directions. Since the screw sleeve 36 is fixedly connected to the slide sleeve 33, the slide sleeve 33 also moves with the screw sleeve 36. Since the connection position of the screw sleeve 36 and the slide sleeve 33 is set in the slide groove 341, it cannot rotate and can only move along the slide groove 341 in the axial direction of the screw rod 35.

[0037] refer to Figure 2 and Figure 4In some embodiments, the first connecting assembly includes a first main connecting rod 16, a second main connecting rod 17, a first secondary connecting rod 15 and a second secondary connecting rod 18; one end of the first main connecting rod 16 and the second main connecting rod 17 are respectively hinged to the two ends of the first main tile 13 facing inward, and one end of the first secondary connecting rod 15 and the second secondary connecting rod 18 are respectively hinged to the inner sides of the two first secondary tile plates 11; the other end of the first secondary connecting rod 15 is hinged to the middle part of the second main connecting rod 17, and the other end of the second secondary connecting rod 18 is hinged to the middle part of the first main connecting rod 16, and the first secondary connecting rod 15 and the second secondary connecting rod 18 are cross-arranged; the other ends of the first main connecting rod 16 and the second main connecting rod 17 are respectively hinged to the two sliding sleeves 33. Through this connecting rod mechanism, when the sliding sleeve 33 moves relative to each other at a long distance, the two first auxiliary tiles 11 can move in the direction away from the first main tile 13. At the same time, due to the change in the angle between the first main connecting rod 16 and the second main connecting rod 17, the first main tile 13 can move outward, that is, expand.

[0038] refer to Figure 1 and Figure 3 In some embodiments, the second connection assembly includes two supports 28 respectively fixed on the two second auxiliary shoe plates, two first connecting rods 25 are hinged at the end of one of the supports 28, and two second connecting rods 26 are hinged at the end of the other support 28. The two first connecting rods 25 are hinged to the two first auxiliary shoe plates 11 at one end of two adjacent active shoe assemblies 1, and the two second connecting rods 26 are hinged to the two first auxiliary shoe plates 11 at the other end of two adjacent active shoe assemblies 1. That is, when the active shoe assembly 1 moves, it drives the driven shoe assembly 2 to move synchronously, thereby realizing the overall synchronous change (expansion or contraction) of the tire building drum device.

[0039] refer to Figure 4 and Figure 5 In some embodiments, a plurality of lugs 331 for connecting with corresponding main connecting rods are evenly arranged on the outer periphery of the sliding sleeve 33, the screw sleeve 36 is arranged in the sliding sleeve 33, and the screw sleeve 36 is connected to the sliding sleeve 33 through a connecting piece 342 arranged in a sliding groove 341, and the sliding sleeve 33 can move along the sliding groove 341. Optionally, the connecting piece 342 can be a solder (i.e., connected by surfacing), or a fastener such as a screw or other connecting piece.

[0040] refer to Figure 2 and Figure 3The first main tile 13 includes a first curved plate and a first shaft seat 14 arranged on the concave surface of the first curved plate, the first auxiliary tile 11 includes a second curved plate and a second shaft seat 19 arranged on the concave surface of the second curved plate, the second main tile 23 includes a third curved plate and a third shaft seat 24 arranged on the concave surface of the third curved plate, the second auxiliary tile includes a fourth curved plate and a fourth shaft seat 28 arranged on the concave surface of the fourth curved plate, the fourth shaft seat 28 is connected to a T-shaped support rod 27, and two first connecting rods 25 are hinged at both ends of the cross rod of the T-shaped support rod; the curvature of each curved plate is the same, and each shaft seat is provided with a through hole cooperating with the corresponding sliding rod and a support connected with the corresponding connecting rod.

[0041] In a possible embodiment, a bearing 32 is provided on the connecting shaft 31 , and a bearing seat may be correspondingly provided on the bearing 32 .

[0042] When this embodiment is used specifically, the tire building drum device is set in the middle of the tire, and the active tile assembly 1 and the driven tile assembly 2 are controlled by the control component 3 to achieve the expansion of the tire. The tire building drum device is placed in the center of the tire, and the drive motor is started to control the screw 35 to rotate. The rotation of the screw 35 will drive the two screw sleeves 36 to move relative to each other, so that the sliding sleeve 33 moves in the sliding groove 341. The movement of the sliding sleeve 33 will drive the first connecting assembly, and then the first main tile plate 13, the first auxiliary tile plate 11 and the second auxiliary tile plate 21 will move outward. The movement of the first main tile plate 13, the first auxiliary tile plate 11 and the second auxiliary tile plate 21 will drive the active tile assembly 1 and the driven tile assembly 2 to expand outward, thereby achieving a synchronous increase in the length and diameter of the tire building drum device.

[0043] By controlling the speed of the driving motor, the speed and strength of the tire expansion can be controlled. The driving motor is reversed to rotate the screw rod 35 in the opposite direction. The reverse rotation of the screw rod 35 drives the two screw sleeves 36 to move in opposite directions, thereby causing the sliding sleeve 33 to move in the opposite direction in the sliding groove 341. Similarly, the length and diameter of the tire building drum device can be reduced synchronously.

The above examples are only used to help understand the method and core ideas of the utility model. The above is only a preferred implementation method of the utility model.
