[0028] Before the tire side passes through the deviation correction of the deviation correction assembly 20, it is pre-centered through the pre-centering assembly 30, the material passing gap formed by the first centering mechanism 32 and the second centering mechanism 33 of the pre-centering assembly 30, the tire side passing through the pre-centering assembly 30 is pre-centered through the material passing gap, so that when the tire side enters the deviation correction assembly 20, the adjustment of the deviation correction assembly 20 can be reduced. The operation specification replacement efficiency and labor intensity are improved. And the first centering assembly and the second centering assembly are movably connected with the connecting shaft 31, that is, the positions of the first centering assembly and the second centering assembly on the connecting shaft 31 can be adjusted, so that different widths of tire side can be adapted, and different working conditions can be adjusted according to the feeding position of the tire side.

[0029] In the present application, the first centering mechanism 32 and the second centering mechanism 33 are both multiple and are arranged in groups one by one.

[0030] Specifically, by setting multiple first centering mechanisms 32 and multiple second centering mechanisms 33, the multiple first mechanisms and the multiple second centering mechanisms 33 can form multiple material feeding gaps, so that multiple sidewalls can be centered at the same time, improving the working efficiency of the equipment.

[0031] The first centering mechanism 32 comprises a first centering frame and a first positioning roller, the first centering frame is slidingly connected with the connecting shaft 31, and the first positioning roller is arranged on the first centering frame. Similarly, the second centering mechanism 33 comprises a second centering frame and a second positioning roller, the second centering frame is slidingly connected with the connecting shaft 31, and the second positioning roller is arranged on the second centering frame.

[0032] In the present application, the connecting shaft 31 is multiple and comprises a first connecting shaft 311 and a second connecting shaft 312, the first centering mechanism 32 is movably connected with the first connecting shaft 311, the second centering mechanism 33 is movably connected with the second connecting shaft 312, and the first connecting shaft 311 and the second connecting shaft 312 are arranged in an upper and lower interval.

[0033] Specifically, the first connecting shaft 311 drives the first centering mechanism 32 to move, and the second connecting shaft 312 drives the second centering mechanism 33 to move, which can facilitate the driving of the first centering mechanism 32 and the second centering mechanism 33, and facilitate the adjustment of the first centering mechanism 32 or the second centering mechanism 33 alone, thereby increasing the flexibility of the adjustment of the first centering mechanism 32 and the second centering mechanism 33.

[0034] In the present application, the first connecting shaft 311 is rotationally connected with the rack 10, the first centering mechanism 32 is threadedly connected with the first connecting shaft 311, and the rotation directions of the threads of the two first centering mechanisms 32 axially adjacent and in different groups are opposite. Since the first connecting shaft 311 has threads with opposite rotation directions, when the first connecting shaft 311 rotates, the first centering mechanisms 32 threadedly connected with the threads with opposite rotation directions are driven to move towards each other or in opposite directions, thereby facilitating the adjustment of the positions of the multiple first centering mechanisms 32 at the same time.

[0035] In the present application, the second connecting shaft 312 is rotationally connected with the rack 10, the second centering mechanism 33 is threadedly connected with the second connecting shaft 312, and the rotation directions of the threads of the two second centering mechanisms 33 axially adjacent and in different groups are opposite. Since the second connecting shaft 312 has threads with opposite rotation directions, when the second connecting shaft 312 rotates, the second centering mechanisms 33 threadedly connected with the threads with opposite rotation directions are driven to move towards each other or in opposite directions, thereby facilitating the adjustment of the positions of the multiple second centering mechanisms 33 at the same time.

[0036] In the present application, the predetermined centering assembly 30 further comprises an auxiliary assembly 34, the auxiliary assembly 34 is arranged at least one of between the first centering mechanism 32 and the second centering mechanism 33, on the side of the first centering mechanism 32 away from the second centering mechanism 33, and on the side of the second centering mechanism 33 away from the second centering mechanism 33, the auxiliary assembly 34 comprises a fixed shaft 341 and a plurality of bidirectional bearings 342, the fixed shaft 341 is arranged on the rack 10 and is parallel to the connecting shaft 31, and the bidirectional bearings 342 are rotationally connected with the fixed shaft 341, and the outer circumferential surface of the bidirectional bearings 342 is used for contacting the tire side.

[0037] Specifically, by replacing the relative sliding between the tire side and the fixed shaft 341 with the rotation of the bearing, the resistance of the tire side passing through the centering assembly can be reduced. By arranging the auxiliary assembly 34 on at least one of between the first centering mechanism 32 and the second centering mechanism 33, on the side of the first centering mechanism 32 away from the second centering mechanism 33, and on the side of the second centering mechanism 33 away from the second centering mechanism 33, the tire side can pass through the predetermined centering assembly 30 more easily, the consumption of useless work is reduced, and the power consumption of the equipment is reduced.

[0038] Referring to Figure 3 The deviation correcting assembly 20 comprises at least two groups of deviation correcting structures 21 and a driving assembly 22, the deviation correcting structures 21 are movably connected with the rack 10, and the driving assembly 22 drives the deviation correcting structures 21 to slide along the axial direction of the connecting shaft 31.

[0039] The deviation correcting structures 21 mainly play a role in correcting the deviation of the tire side. Due to the existence of the predetermined centering assembly 30, the position of the tire side entering the deviation correcting assembly 20 is different each time, so the position of the deviation correcting structure 21 is adjusted to facilitate the adaptation of the predetermined centering assembly 30 with different feeding positions.

[0040] The problem that when the center distance of the tire side changes greatly, the deviation correcting roller driving mechanism cannot follow the movement and the deviation correcting roller is stuck after being rotated to the limit and cannot continue to move is solved.

[0041] In the present application, the driving assembly 22 comprises a screw rod, opposite threads are arranged at the two ends of the screw rod, and the two groups of deviation correcting structures 21 are respectively threadedly connected with the threads at the two ends of the screw rod.

[0042] Specifically, since opposite threads are arranged at the two ends of the screw rod, when the screw rod rotates, the deviation correcting structures 21 threadedly connected with the threads at the two ends of the screw rod will simultaneously move towards each other or away from each other, and by arranging the positive and negative threads at the two ends of the screw rod, the plurality of deviation correcting structures 21 can be simultaneously driven to move.

[0043] In the application, the deviation rectifying structure 21 comprises a fixing frame 211, a roller frame 212, a roller shaft, a driving member 214 and a transmission structure. The fixing frame 211 is movably connected with the rack 10 along the axial direction of the connecting shaft 31. The roller frame 212 is rotatably connected with the fixing frame 211. The roller 213 is rotatably sleeved on the roller frame 212. The rotation axis of the roller frame 212 relative to the fixing frame 211 is perpendicular to the conveying direction of the sidewall, so as to change the angle of the roller 213 relative to the conveying direction of the sidewall. The driving member 214 is arranged on the fixing frame 211. The driving member 214 provides driving force for the movement of the roller frame 212. The transmission structure 215 is arranged on the fixing frame 211. The driving member 214 drives the roller frame 212 to move through the transmission structure 215.

[0044] When it is necessary to rectify the deviation of the sidewall, the driving member 214 provides driving force for the transmission structure 215, so as to drive the roller frame to rotate on the fixing frame 211. After the roller frame rotates, an angle is formed between the roller frame and the advancing direction of the sidewall. Thus, when the sidewall passes through the roller frame, the movement track of the sidewall will change due to the angle of the roller frame, so as to rectify the deviation of the sidewall.

[0045] Meanwhile, the problem that the sidewall is easily stopped due to automatic deviation rectification triggering limit when the inner spacing of the sidewall after the crimping in the previous process is greatly different from the production specification and the operator needs to recover is solved.

[0046] In the application, the transmission structure 215 comprises a sliding frame 216, a connecting rod 217 and a deflection rod 218. The driving member 214 drives the sliding frame 216 to move. One end of the connecting rod 217 is hingedly connected with the sliding frame 216. The other end of the connecting rod 217 is hingedly connected with the deflection rod 218. The roller frame 212 is fixedly connected with the end of the deflection rod 218 away from the connecting rod 217.

[0047] Specifically, the driving member 214 drives the sliding frame 216 to move. After the sliding frame 216 moves, the connecting rod 217 connected with the sliding frame 216 will move, and then the deflection rod 218 connected with the connecting rod 217 will deflect. Since the deflection rod 218 is fixedly connected with the roller frame 212, the deflection rod 218 will drive the roller frame to rotate after the deflection rod 218 deflects. Preferably, the driving member 214 comprises a motor belt transmission assembly. The sliding frame 216 is connected with the connecting block and the belt. The movement of the belt drives the movement of the sliding frame 216, so as to conveniently provide driving force for the transmission structure 215.

[0048] In the application, the transmission structure 215 further comprises a limiting slide rail 23 and a limiting block 24. The extending direction of the limiting slide rail 23 is the same as the axial direction of the connecting shaft 31. The limiting block 24 is arranged on the sliding frame 216. The limiting block 24 is slidably connected with the limiting slide rail 23.

[0049] Specifically, through the cooperation of the limiting slide rail 23 and the limiting block 24, the stability of the sliding frame 216 sliding can be increased, the stability of the transmission structure 215 movement is improved, thereby the swing effect of the roller shaft frame is improved, and the working efficiency of the equipment is improved.

[0050] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0051] 1、In the tire side passes through the deviation rectification assembly 20 deviation rectification before, first through the predetermined centering assembly 30 carries out the predetermined centering, through the first centering mechanism 32 and the second centering mechanism 33 of predetermined centering assembly 30 Formed between the material gap, through the material gap to the tire side that passes through the predetermined centering assembly 30 carries out the predetermined centering, like this when the tire side enters into the deviation rectification assembly 20, can reduce the adjustment of deviation rectification assembly 20.It improves the operation specification replacement efficiency and labor intensity.And the first centering assembly and the second centering assembly are movably connected with the connecting shaft 31, that is, the position of the first centering assembly and the second centering assembly on the connecting shaft 31 can be adjusted, so that it can not only adapt to different width of the tire side, but also can be adjusted according to the different feeding position of the tire side, adapt to different working conditions.

[0052] 2、Through the setting of multiple first centering mechanisms 32 and multiple second centering mechanisms 33, multiple first mechanisms and multiple second centering mechanisms 33 can form multiple material gaps, so that multiple tire sides can be centered at the same time, improving the working efficiency of the equipment.

[0053] 3、Through the cooperation of the limiting slide rail 23 and the limiting block 24, the stability of the sliding frame 216 sliding can be increased, the stability of the transmission structure 215 movement is improved, thereby the swing effect of the roller shaft frame is improved, and the working efficiency of the equipment is improved.
