The cutter driving member 15 is used to drive the cutter 16 to rotate, so as to realize the cutter 16 extending out and retracting the cutter mounting frame 9. During operation, the crown band strip conveying device winds the crown band strip 11 on the belt drum 13. After the winding is completed, the cutter 16 is driven by the cutter driving member 15 to extend out of the cutter mounting frame 9 to cut the crown band strip 11. The above structure is adopted to realize the functions of winding the band strip 11 and cutting the band strip 11 by the band strip winding machine head, and the operator does not need to manually cut the band strip 11, thereby reducing the labor intensity of the operator.

[0035] The cutter 16 in the present application is mounted on the rotating shaft, and when the cutter drive 15 drives the rotating shaft to rotate, the position of the cutter 16 relative to the cutter mounting frame 9 can be changed, so that the cutter 16 can be extended and retracted. Specifically, the cutter 16 is located in the tangential direction of the rotating shaft.

[0036] The crown strip conveying device in the present application includes a base plate 1, a transition plate 3 and a power device 2, wherein the transition plate 3 can slide along the base plate 1, specifically, the transition plate 3 can slide in the direction toward and away from the belt drum 13, and the cutter mounting frame 9 is hinged at one end of the transition plate 3 close to the belt drum 13. The above-mentioned power device 2 is used to drive the transition plate 3 to move. Specifically, the base plate 1 is located at the bottom of the mechanism, and under the drive of the power device 2, the overall forward and backward movement of the winding head mechanism can be ensured; the power device 2 is fixed above the base plate 1, and can drive the transition plate 3 so that it can move forward and backward. By adjusting the position of the transition plate 3, the distance from the crown strip 11 to the belt drum 13 can be changed. The power device 2 of the present application can be a motor or a cylinder assembly. The distance of movement of the transition plate 3 can be set according to actual requirements, and all are within the protection range.

[0037] The above-mentioned crown band conveying device also includes a bonding roller 10, and the bonding roller 10 is located at the end of the transition plate 3 close to the belt drum 13 and is capable of bonding with the belt drum 13. Specifically, the bonding roller 10 is located between the above-mentioned cutter mounting frame 9 and the belt drum 13. In order to ensure the stability of the bonding of the crown band 11, the distance between the center of the bonding roller 10 disclosed in the present application and the bottom plate 1 is equal to the distance between the center of the belt drum 13 and the bottom plate 1, so as to ensure that the crown band 11 is wound on the belt drum 13 and the winding is completed, thereby ensuring the bonding stability of the crown band 11 and the belt drum 13.

[0038] In a specific embodiment, the above-mentioned transition plate 3 is installed on the bottom plate 1 through a slider 14, and the slider 14 can slide along the slide rail on the bottom plate 1, and the slide rail is perpendicular to the axis of the belt drum 13. The transition plate 3 is moved on the bottom plate 1 by the cooperation of the slider 14 and the slide rail. In practice, the movement of the transition plate 3 can also be achieved by the cooperation of the lead screw nut. It can be understood by those skilled in the art that all methods for achieving the movement of the transition plate 3 on the bottom plate 1 are within the protection scope.

[0039] In a preferred embodiment, the above-mentioned crown band conveying device further includes: a sliding seat 5, a stop block 7 and a driving device 6, wherein the sliding seat 5 is slidably mounted on the transition plate 3, and the stop block 7 is rotatably mounted on the sliding seat 5, the stop block 7 abuts against the crown band 11 and restricts the crown band 11 from moving in a direction away from the belt drum 13, and the above-mentioned driving device 6 is used to drive the stop block 7 to rotate, and during the rotation of the stop block 7, the crown band 11 can be released so that the crown band 11 is wound around the belt drum 13, and since the stop block 7 cannot rotate in the opposite direction, the crown band 11 is avoided from being recovered. Such a configuration can ensure that the crown band 11 can be normally conveyed and prevent the crown band 11 from skipping.

[0040] In a specific embodiment, the stop block 7 has an inclined surface, and the inclined side of the inclined surface faces the belt drum 13. This arrangement ensures that the stop block 7 can rotate in the direction of conveying the crown band strip 11, and is stuck in the reverse direction of conveying the crown band strip 11, and cannot rotate, thereby achieving one-way conveying. The function of the stop block 7 and the driving device 6 here is to limit the conveying direction of the crown band strip 11.

[0041] In a further embodiment, a spring seat is fixed on the above-mentioned transition plate 3, and the sliding seat 5 is connected to the spring seat through the spring 4. During operation, the sliding seat 5 slides toward the belt drum 13 under the action of the spring 4 until it slides to the waiting position to ensure that the position of the crown band 11 is fixed. Only one method of driving the sliding seat 5 to move is disclosed here, and other driving methods can also be used in practice.

[0042] In a further embodiment, the cap band winding machine head in the present application also includes a pressing roller 12 mounted on the cutter mounting frame 9, and the pressing roller 12 can be fitted with the belt drum 13 when the cutter 16 extends out of the cutter mounting frame 9 and cuts the cap band 11. The function of the pressing roller 12 disclosed in the present application is to ensure the stability of the cap band 11 fitting on the belt drum 13. Ensure that the end of the cap band 11 is completely fitted. When working, the pressing roller 12 does not fit with the belt drum 13 during the winding process, and when the cutter 16 cuts the cap band 11, the pressing roller 12 needs to fit with the belt drum 13. The pressing roller 12 presses the cut end of the cap band 11 to the surface of the belt layer drum 13.

[0043] The crown band strip winding machine head disclosed in the present application also includes an elastic pressing sheet 8 arranged on the transition plate 3 for pressing the crown band strip 11 after the cutting knife 16. The elastic pressing sheet 8 can be pressed down when the crown band strip 11 is fitted and cut to ensure that the position of the crown band strip 11 is correct and consistent when the material head is fitted.

[0044] When used, the main process steps are as follows:

[0045] The power device 2 and the transition plate 3 are in the waiting position, the spring 4 pushes the sliding seat 5 to the waiting position in the direction of the belt drum 13, the elastic pressing plate 8 is lifted, the cutter 16 swings back to the cutter mounting frame 9, the pressing roller 12 does not contact the belt drum 13, and the crown band 11 is wound normally; the entire mechanism completes the winding according to the established procedure, and the belt drum 13 stops rotating; the cutter 16 swings out of the cutter mounting frame 9 around its rotation axis under the action of the cutter driving member 15, and the pressing roller 12 contacts the belt drum 13. The backstop cylinder extends out, and the backstop block 7 swings to press the crown band 11. The cutter 16 cuts the crown band strip 11; the belt drum 13 rotates again to fit the tail of the crown band strip 11 to the belt drum 13, and the anti-retraction cylinder retracts; at this time, under the control of the tension of the crown band strip storage rack, there is a tendency to pull the crown band strip 11 back to the storage rack, and the anti-retraction block 7 presses and fixes the crown band strip 11, and the crown band strip 11 pulls the sliding seat 5 to compress the spring 4 to the working position, and the elastic pressing piece 8 is pressed down; the cutter drive member 15 drives the cutter 16 to swing back to the waiting position; when fitting again, the power device Device 2 pushes the transition plate 3 toward the belt drum 13 to the working position, and the laminating roller 10 presses the crown strip 11 onto the belt drum 13 to complete the laminating of the crown strip 11. After the belt drum 13 starts to slowly rotate at a certain angle, the power device 2 pulls the transition plate 3 back to the waiting position; the sliding seat 5 slides toward the belt drum 13 under the action of the spring 4 until it slides to the waiting position, and at the same time lifts the elastic pressing plate 8; the belt drum 13 gradually increases the rotation speed to wind the crown strip 11 until the winding is completed.

[0046] In addition, the present application also discloses a tire processing device, including a cap strip winding head, wherein the cap strip winding head is the cap strip winding head disclosed in the above embodiment.
