[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The methods used in the present utility model are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercial products unless otherwise specified.

[0025] Example 1

[0026] Depend on Figure 1 , Figure 2 As shown, the utility model provides a crown band transverse movement guide device, which includes a crown band transverse movement platform 1 and a linear reciprocating power device, wherein:

[0027] The cap band transverse movement platform 1 is connected to two guide rollers 2, and a limiting gap 3 is formed between the two guide rollers 2 for the cap band to pass through.

[0028] The linear reciprocating power device includes a forward and reverse motor 4, the power output shaft of the forward and reverse motor 4 is transmission-connected to the lead screw 5, the lead screw 5 is rotationally connected to the support seat 7, and the rotation connection is usually connected by a bearing 6; the lead screw 5 is cooperatively connected to the nut seat 8, and the nut seat 8 is fixedly connected to the crown strip transverse movement platform 1.

[0029] When in use, the utility model is installed between the existing cap band supply rack and the belt drum, and the belt layer is first wound on the belt drum, and then the initial end of the cap band is led out from the cap band supply rack, and after passing through the limiting gap 3 between the two guide rollers 2, it is fixed on the outside of the belt layer on the belt drum. The belt drum is started, and the belt drum rotates, driving the cap band to be continuously led out from the cap band supply rack and wound on the outside of the belt layer. The forward and reverse motor 4 is started, and the screw 5 is driven to rotate forward and reverse under the power output of the forward and reverse motor 4. Through the threaded cooperation between the screw 5 and the nut in the nut seat 8, the cap band transverse moving platform 1 is driven to make linear reciprocating motion in the transverse direction, thereby driving the cap band passing through the limiting gap 3 between the two guide rollers 2 to make linear reciprocating motion in the transverse direction, realizing the transverse reciprocating movement in the width direction of the belt layer during the cap band winding process, meeting the molding production requirements of tires with larger tread widths.

[0030] In order to make the transverse movement of the crown band strip transverse movement platform 1 more stable, the utility model is further provided with a guide rod 9, which is connected to the support seat 7 and is arranged parallel to the lead screw 5; the guide rod 9 passes through the transverse movement slider 10, and the guide rod 9 is slidably connected to the transverse movement slider 10. The transverse movement slider 10 is fixedly connected to the crown band strip transverse movement platform 1.

[0031] In order to make the crown strip transverse platform 1 more firmly fixed to the nut seat 8 and the transverse slider 10, the nut seat 8 is fixedly connected to the transverse slider 10. The fixed connection method can be key 11 connection, welding, mosaic, one-piece molding and the like.

[0032] In order to further improve the accuracy of the crown band positioning and the uniformity of the winding, the screw 5 is a ball screw.

[0033] In order to make the cap band strip pass through the limiting gap 3 between the two guide rollers 2 more smoothly, the two guide rollers 2 are arranged in parallel.

[0034] In order to make the crown band strip pass through the utility model more smoothly, a plurality of spherical balls 12 are distributed and installed on the two crown band strip transverse moving platforms 1 arranged on the same side as the guide rollers 2. When in use, the bottom of the crown band strip and the spherical balls 12 are in rolling friction contact, ensuring that the adjustment of the orientation and angle of the crown band strip during the transverse movement and transmission of the crown band strip is more convenient and flexible, and promoting smoother transverse back and forth movement and transmission of the crown band strip.

[0035] Example 2

[0036] Depend on Figure 1 , Figure 3 As shown, the utility model provides a crown band transverse movement guide device, and its technical solution is different from that of Example 1 in that the nut seat 8 is not connected to the crown band transverse movement platform 1. Other contents are the same as those of Example 1 and will not be repeated here.

[0037] Since the nut seat 8 is fixedly connected to the lateral sliding block 10, and the lateral sliding block 10 is fixedly connected to the crown band transverse moving platform 1, the power output shaft of the forward and reverse motor 4 drives the lateral sliding block 10 to make a lateral linear reciprocating movement along the guide rod 9 through the matching lead screw 5 and the nut seat 8, and finally realizes the lateral linear reciprocating movement of the crown band transverse moving platform 1.

[0038] Example 3

[0039] Depend on Figure 1-Figure 3 As shown, based on the technical solution of embodiment 1 or embodiment 2, the utility model is further provided with an intelligent control system and a speed sensor 13. Among them:

[0040] The intelligent control system is provided with an intelligent control device 14, which is usually a PLC (programmable logic controller) and can program related programs in the PLC; the intelligent control device 14 is electrically connected to the speed sensor 13 and the forward and reverse motor 4 through control lines.

[0041] The rotation speed sensor 13 is installed on the existing driving motor shaft of the belt drum, and is used to monitor the rotation speed of the driving motor shaft of the belt drum and transmit a sensing signal.

[0042] When in use, the belt drum is started to rotate, and the forward and reverse motor 4 is started. At this time, under the rotation of the belt drum, the cap band strip is driven to be continuously led out and wound on the outside of the belt layer; driven by the forward and reverse motor 4, the cap band strip transverse moving platform 1 makes a linear reciprocating motion in the transverse direction, thereby driving the cap band strip passing through the limiting gap 3 between the two guide rollers 2 to make a linear reciprocating motion in the transverse direction, so as to realize the transverse reciprocating movement of the cap band strip on the belt layer during the winding process. During the rotation of the belt drum, the speed sensor 13 monitors the rotation speed of the belt drum in real time, and transmits the rotation speed to the intelligent control device 14 through the control line in the form of an induction signal. After receiving the induction signal, the intelligent control device 14 sends an instruction to the forward and reverse motor 4. After receiving the instruction, the forward and reverse motor 4 performs a corresponding action, that is, according to the actual situation, when the rotation speed of the belt drum increases, the speed of the drive shaft of the forward and reverse motor 4 increases accordingly, and when the rotation speed of the belt drum slows down, the speed of the drive shaft of the forward and reverse motor 4 slows down accordingly, so as to ensure that the crown strip is evenly wound around the outside of the belt layer in the transverse width direction, thereby realizing automatic control.

[0043] It should be noted that:

[0044] (1) In addition to using a forward and reverse motor 4 to drive the matching lead screw 5 and nut seat 8 to drive the crown strip transverse moving platform 1 to move horizontally and linearly, the linear reciprocating power device of the utility model can also use existing mechanisms such as a cylinder / oil cylinder, a crank connecting rod, etc.

[0045] (2) The forward and reverse motor 4 can be a DC motor, a three-phase asynchronous motor, a stepper motor, a servo motor, etc.

[0046] (3) In the intelligent control system of the utility model, there are also existing modules, such as a power supply module for supplying power to equipment or electronic components such as a speed sensor 13, a forward and reverse motor 4, and an intelligent control device 14. Since these belong to the prior art, they will not be described here.

[0047] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
