[0029] By arranging the stitching and pressing roller device 30 on one side of the forming drum 20, when the joint of the tire material is needed, the tire material is pressed by the stitching and pressing roller, compared with the manual pressing method, the automation of the product can be improved. And the pressing roller is arranged to be radially movable relative to the forming drum 20, which can contact the tire material when pressing is needed, and move away from the tire material when pressing is not needed, and can adapt to tire materials of different sizes and diameters.

[0030] In the present application, the peripheral side of the forming drum 20 has a transversely arranged operation side and a non-operation side, the operation side is used for personnel operation, and the stitching pressure roller device 30 is located on the operation side.

[0031] Specifically, the peripheral side of the forming drum 20 has a transversely arranged operation side and a non-operation side, the operation side has a certain space for the operation and use of the workers and the arrangement of part of the parts, and the non-operation side can be located near the wall or provided with other equipment, which is not convenient for the arrangement of parts. Therefore, the stitching pressure roller device 30 is arranged on the operation side, which is convenient for the arrangement of the stitching pressure roller device 30.

[0032] Referring to Figures 3 to 5 , the stitching pressure roller device 30 comprises a frame body 31, a connecting frame 32 and a pressure roller assembly 33, the frame body 31 is located on one side of the rack 10; the connecting frame 32 is arranged on the frame body 31; the pressure roller assembly 33 comprises a support frame and a pressure roller, the support frame is movably connected with the connecting frame 32, and the pressure roller is arranged at one end of the support frame close to the rack 10 and is rotationally connected with the support frame.

[0033] Specifically, the pressure roller of the pressure roller assembly 33 presses the tire material, the movable connection between the support frame of the pressure roller assembly 33 and the connecting frame 32 can drive the pressure roller to approach or move away from the tire material, which is convenient for controlling the pressing of the tire material by the pressure roller assembly 33 and adapting to tire materials of different sizes.

[0034] In the present application, the stitching pressure roller device 30 further comprises a driving member 34, the driving member 34 is installed on the connecting frame 32, the driving member 34 is drivingly connected with the support frame, and the driving member 34 drives the support frame to move towards the direction close to or away from the rack 10.

[0035] The driving member 34 drives the support frame to move, which is convenient for controlling the working state of the pressure roller. Preferably, the driving member 34 is a pneumatic cylinder, which drives the movement of the pressure roller by the extension or retraction of the piston rod of the pneumatic cylinder, which is convenient for driving the pressure roller. At the same time, the pneumatic cylinder drives the pressure roller, which is convenient for improving the automation of the stitching pressure roller device 30.

[0036] In the present application, the extruder stitching pressure roller device 30 further comprises an adjusting assembly 35, the adjusting assembly 35 is arranged on the frame body 31, and the connecting frame 32 is arranged on the adjusting assembly 35. The adjusting assembly 35 adjusts the distance between the pressure roller and the rack 10.

[0037] When the pressure roller presses the tire material, the pressure roller needs to maintain a certain adhesion pressure with the tire material to ensure the adhesion effect of the rubber material. Therefore, when the size of the tire material to be pressed changes greatly, the position of the connecting frame 32 and the pressure roller needs to be adjusted by the adjusting assembly to ensure the adhesion pressure of the pressure roller to the tire material.

[0038] Referring to Figure 4The adjusting assembly 35 comprises at least one fixing base 351, a screw rod 352 and a connecting base 353. The fixing base 351 is connected with the frame body 31. The screw rod 352 is rotationally connected with the fixing base 351. The axial direction of the screw rod 352 is the same as the moving direction of the supporting frame. The connecting base 353 is threadedly connected with the screw rod 352. The connecting base 353 is movably arranged on the frame body 31. The connecting base 353 is connected with the connecting frame 32.

[0039] When it is needed to change the position of the compression roller assembly 33, since the connecting base 353 is threadedly connected with the screw rod 352, when the screw rod 352 is rotated, the connecting base 353 will be displaced along the axial direction of the screw rod 352, so as to adjust the position of the connecting base 353 and change the position of the compression roller assembly 33. The position of the compression roller assembly 33 is adjusted according to the size of the tire material to be compressed, so as to adapt to tire materials of different sizes.

[0040] In the application, the adjusting assembly 35 further comprises a locking assembly 354. The locking assembly 354 is connected with the screw rod 352. The locking assembly 354 has a locking position for locking the rotated screw rod 352 and an unlocking position for releasing the screw rod 352.

[0041] Specifically, after the position of the connecting base 353 is adjusted, the screw rod 352 is locked by the locking assembly 354. At this time, the screw rod 352 cannot continue to rotate, so that the position of the connecting base 353 cannot be adjusted. The compression roller assembly 33 always moves at the same position under the action of the driving member 34, thereby increasing the stability of the tire material processing by the compression roller assembly 33.

[0042] In the application, the locking assembly 354 comprises a fixing block 355 and a locking block. The fixing block 355 is arranged on the fixing base 351.

At this time, the frictional resistance between the locking member 356 and the screw rod 352 is increased, so as to realize the locking of the screw rod 352. When there is a gap between the locking member 356 and the screw rod 352, the locking member 356 cannot increase the rotating resistance of the screw rod 352, so the locking of the screw rod 352 cannot be realized. By adjusting the position of the locking member 356, the locking or unlocking of the screw rod 352 can be conveniently controlled. Preferably, the locking member 356 is a bolt or a clamping handle.

[0044] In the application, the edge of the connecting frame 32 has a protruding portion 321. The connecting frame 32 has a limiting block 322. The supporting frame is located between the protruding portion 321 and the limiting block 322.

[0045] The convex part 321 and the limiting block 322 can together limit the sliding of the compression roller assembly 33, and the stability of the movement of the compression roller assembly 33 is increased.

[0046] Referring to Figure 3 The extruder stitching compression roller device 30 further comprises a driving assembly 36, the frame body 31 is arranged on the driving assembly 36, the driving assembly 36 is located on one side of the rack 10, and the driving assembly 36 drives the frame body 31 to move relative to the rack 10 along the length direction of the rack 10.

[0047] Specifically, the driving assembly 36 drives the frame body 31 to drive the stitching compression roller device 30 to move along the length direction of the rack 10, when the stitching compression roller device 30 needs to work, the stitching compression roller device 30 is moved to one side of the forming drum 20, when the stitching compression roller device 30 does not need to work, the stitching compression roller device 30 is moved to other positions, and the overall work of the forming machine and the work of other workpieces are not affected.
