Description

Technical Field

[0001] The invention relates to the technical field of tread winding, and in particular to an automatic anti-rebound tread winding device. Background Art

[0002] The tread is the part of the tire that comes in direct contact with the ground, and is composed of the crown rubber, base rubber, and lower tread rubber. It is not only the interface that the tire contacts the ground when driving, but also has multiple functions such as protecting the tire body, providing drive, traction, braking, drainage, anti-skid, shock absorption, and steering.

[0003] The production process of the tread generally includes the steps of raw material mixing, skeleton weaving, tread molding and cooling and shaping. After the tread is cooled and shaped, a winding device is needed to wind up the tread for storage and transportation.

[0004] The winding device is usually composed of a driving motor, a limit shaft and a winding roller. The tread is fixed in the winding roller, and the driving motor drives the limit shaft and the winding roller to rotate, so that the tread can be stably wound.

[0005] When the tread is rolled up by the winding device, since the tread is made of rubber material, the tread itself has a certain elasticity. Therefore, during the rolling process of the tread, there will be a certain rebound force, which will cause the rolled tread to rebound, and the tread after rebound is too loose. If the rolling force is too large, the rebound force of the tread will also increase, and the rebounding tread is likely to cause injury to the staff. In addition, in order to keep the tread from being too loose during rolling, the winding tension will be adjusted by the tension mechanism, that is, pressure is applied to the tread by the tension roller. However, as the tread is continuously rolled up, the diameter of the tread roll will increase, thereby increasing the tension on the tread, causing the tread to be rolled up too tightly. When the tread is rolled up too tightly, it will cause the tread to remain in a bent state after being unfolded and cannot be unfolded quickly. In addition, excessive tension will cause the tread to be subjected to excessive pulling force, which can easily cause the tread to be stretched and deformed, causing the thickness of the tread to change, resulting in a deviation between the tread and the actual thickness.

[0034] Specifically, the adjustment component includes a limit slider 23, the limit slider 23 is slidably connected to the inner wall of the limit frame 3, the inner wall of the limit slider 23 is rotatably connected to an adjusting roller 24, the inner wall of the limit frame 3 is rotatably connected to an auxiliary roller 25, the number of the auxiliary rollers 25 is multiple, and the multiple auxiliary rollers 25 are symmetrically arranged with the vertical center line of the front side of the limit frame 3 as the symmetry axis, and are used to assist the tread to move in a curve for winding work, so as to assist the adjusting roller 24 to adjust the winding tension of the tread, and the lifting mechanism includes a limit ring 26, the limit ring 26 is fixedly connected to the surface of the limit frame 3, the inner wall of the limit ring 26 is rotatably connected to a threaded rod 27, and the surface of the threaded rod 27 is threadedly connected There is a threaded sleeve 28, and the threaded sleeve 28 is fixedly connected to the front side of the limit slider 23.

[0035] Specifically, the cutting mechanism includes a linear motor 32, which is fixedly connected to the left side of the limit frame 3, and a connecting block 33 is fixedly connected to the movable end of the linear motor 32, and a cutting tool 34 is fixedly connected to the bottom surface of the connecting block 33. When the sliding rheostat 10 detects that the tread winding diameter reaches a preset value, the cutting mechanism is started to cut the tread and the oil paper, so as to complete a single winding work after the tread is cut, which is convenient for controlling the winding diameter of the tread.

[0036] When in use: first, the cooled and shaped tread is pulled along the bottom of the auxiliary roller 25 and the top of the adjusting roller 24 to the winding roller 14 for fixing, and the oil paper is unrolled through the oil paper roller 17 and fixed between the tread and the winding roller 14, and the servo motor 18 is started to drive the driving wheel 19 and the transmission belt 20 to rotate, and the transmission belt 20 is engaged with the first driven wheel 21 and the second driven wheel 22 to drive the limit shaft 13 and the winding roller 14 to rotate along the inner wall of the connecting frame 12 to reel the tread and the oil paper, and at the same time drive the oil paper roller 17 along the support The inner wall of the plate 16 rotates to unwind the oil paper.

The movement of the connecting shaft 6 drives the fixed frame 7 and the pressure roller 8 to move downward and contact the tread. After the pressure roller 8 is subjected to force, it pushes the connecting shaft 6 to slide upward along the inner wall of the connecting plate 5 through the fixed frame 7, and at the same time squeezes the spring 9. The rebound force generated by the spring 9 can push the fixed frame 7 and the pressure roller 8 to move downward to apply stable pressure to the tread, which can prevent the tread from rebounding and loosening. When the winding thickness of the tread increases, the connecting shaft 6 will gradually move upward due to the thrust. The movement of the connecting shaft 6 pushes the lifting plate 11 and the moving end of the sliding rheostat 10 to move upward. The movement of the sliding end of the sliding rheostat 10 can change the length of the internal resistance wire to control the size of the resistance. When the reduction state of the resistance is detected, the current winding thickness of the tread can be measured. When the tread thickness increases and the winding tension increases, the dual-axis motor 29 is started to drive the first bevel gear 30 to rotate. The meshing of the two bevel gears 31 drives the threaded rod 27 to rotate along the inner wall of the limit ring 26. The threaded connection between the threaded rod 27 and the threaded sleeve 28 drives the limit slider 23 to move downward along the inner wall of the limit frame 3. The movement of the limit slider 23 drives the adjusting roller 24 and the tread to move downward, thereby gradually reducing the winding tension of the tread. When the sliding rheostat 10 detects that the tread winding thickness reaches the specified position, the linear motor 32 is started to drive the connecting block 33 and the cutting tool 34 to move backward to cut the rear oil paper of the tread.
