[0041] like Figures 1 to 3 As shown, a tire building machine laminating drum rotating device includes a horizontally arranged base plate 10, on which a motor 20 and a transmission assembly 30 are arranged, the motor shaft of the motor 20 is connected to the input end of the transmission assembly 30, the output end of the transmission assembly 30 is a rotating structure, and a rotating platform 40 is arranged on the output end of the transmission assembly 30, so that the motor 20 drives the rotating platform 40 to rotate in a horizontal plane through the transmission assembly 30, and the rotating platform 40 rotates 180° each time.

[0042] In order to improve the rotation efficiency of the rotating platform 40, it is best to use a variable frequency motor for the motor 20, and the motor 20 is connected to a controller for controlling the speed of the motor 20 (especially a microprogram controller, which changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit according to program instructions to control the starting, speed regulation, braking and reversal of the motor), so that the rotating platform 40 has different rotation speeds in different rotation ranges.

[0043] like Figure 1 and 2 As shown, in order to enable the controller to accurately know the position of the rotating platform 40, thereby controlling the motor 20 to be at a corresponding speed, a detection plate 41 is provided on opposite sides of the rotating platform 40. The detection plate 41 extends around the rotation axis of the rotating platform 40, and the detection plate 41 needs to have a certain length. To be precise, the detection plate 41 is an arc-shaped flat plate with the rotation axis of the rotating platform 40 as the center (see Figure 1), which is to facilitate the proximity switch 52 described later to detect the position of the detection plate 41. Corresponding to the detection plate 41, detection components 50 are arranged on opposite sides of the bottom plate 10. The detection components 50 are used to detect the position of the detection plate 41 and transmit the detected data to the controller. The controller determines the position of the rotary platform 40 based on these data, and then controls the speed of the motor 20.

[0044] When the rotating platform 40 is stationary, the detection plates 41 on both sides of the rotating platform 40 correspond to a detection assembly 50 respectively. When the motor 20 is started, the rotating platform 40 starts to rotate, so that the detection plate 41 starts to rotate around the axis and gradually leaves the corresponding detection assembly 50. Since the detection plate 41 has a certain length, the detection assembly 50 can still detect the existence of the detection plate 41 within a period of time. During this period of time, the controller controls the motor 20 to increase the rotation speed, so that the rotating platform 40 increases the rotation speed until the detection plate 41 completely leaves the detection assembly 50. At this time, the controller controls the motor 20 to keep the rotation speed unchanged, and the rotating platform 40 rotates at a constant speed. When the head end of the detection plate 41 moves to the top of the detection assembly 50 on the other side, the controller controls the motor 20 to start decelerating, and the speed of the rotating platform 40 gradually decreases. Since the detection plate 41 has a certain length, the motor 20 has enough time to decelerate, and when the motor 20 decelerates to 0, the tail end of the detection plate 41 is just located at the limit position of the detection assembly 50, and the rotating platform 40 also just completes the positioning.

[0045] Specifically, Figure 1 and 2 As shown, the detection plate 41 is an arc-shaped flat plate, and extends outwardly beyond the side of the rotary platform 40. The detection assembly 50 includes a switch mounting seat 51 and a proximity switch 52. The switch mounting seat 51 is an arc-shaped flat plate matching the appearance of the detection plate 41. The switch mounting seat 51 is located below the detection plate 41, and a proximity switch 52 arranged upward is installed at both ends of the switch mounting seat 51. When the rotary platform 40 is stationary, the detection plate 41 is located above the switch mounting seat 51, and the two ends of the detection plate 41 correspond to a proximity switch 52 respectively. When the detection plate 41 is rotating, the tail end of the detection plate 41 first leaves the top of one of the proximity switches 52, but the middle part of the detection plate 41 is still located above the other proximity switch 52, that is, the other proximity switch 52 can still sense the position of the detection plate 41, and the motor 20 needs to increase the speed at this time. When the detection plate 41 leaves the detection assembly 50 as a whole, that is, when both proximity switches 52 cannot detect the detection plate 41, the motor 20 keeps rotating at a constant speed. When the head end of the detection plate 41 moves to above a proximity switch 52 on the other side, the motor 20 starts to decelerate until the motor speed is 0, and the two ends of the detection plate 41 just correspond to the two proximity switches 52 on the other side, ensuring the accuracy of the position of the rotating platform 40.

[0046] By setting detection plates 41 on opposite sides of the rotating platform 40 and correspondingly setting detection components 50 on the bottom plate, the controller can accurately know the position of the rotating platform 40, thereby changing the rotation speed of the motor 20 accordingly, thereby improving the rotation efficiency of the rotating platform 40 and also improving the positioning accuracy of the rotating platform 40.

[0047] like Figure 3 As shown, as an example of a transmission assembly 30, the transmission assembly 30 includes a longitudinally arranged transmission shaft 31, and a gear structure is connected to the upper end of the transmission shaft 31. The input end of the gear structure is connected to the transmission shaft 31, and the output end is connected to the rotating platform 40, so that the motor 20 drives the transmission shaft 31 to rotate, and the transmission shaft 31 drives the rotating platform 40 to rotate through the gear structure.

[0048] Specifically, the gear structure includes a first gear 32 , which rotates synchronously with the transmission shaft 31 , and a second gear 33 is meshed with the first gear 32 . The rotary platform 40 is coaxially fixed with the second gear 33 and rotates synchronously with the second gear 33 .

[0049] It should be noted that the transmission shaft 31 can be a single shaft, or a motor shaft or an output shaft of a reducer. In addition, the first gear 32 can also be a worm, and the rotation of the rotary platform 40 in the horizontal plane is achieved through the cooperation of the worm and the gear.

[0050] like Figure 2 As shown, a bearing seat 34 in the shape of a hollow sleeve and with an axis extending in the longitudinal direction is arranged on the bottom plate 10, a fixing seat 35 is arranged inside the bearing seat 34, the bottom of the fixing seat 35 is arranged on the bottom plate 10, the outer wall surface of the fixing seat 35 is a cylindrical surface, and a distance is left between the outer wall of the fixing seat 35 and the inner wall of the bearing seat 34. A rotating shaft 36 is rotatably arranged on the outer wall surface of the fixing sleeve 35, the rotating shaft 36 is a hollow shaft and the axis extends in the longitudinal direction, the inner wall of the rotating shaft 36 is connected to the outer wall surface of the fixing sleeve 35, and an adjusting nut is arranged on the upper part of the rotating shaft 36, and the rotating shaft 36 is axially fixed to the fixing sleeve 35 by the adjusting nut. A bearing 37 is arranged between the outer wall of the rotating shaft 36 and the inner wall of the bearing seat 34, so that the rotating shaft 36 rotates in the space formed by the fixing seat 35 and the bearing seat 34. The second gear 33 is arranged on the outer wall surface of the rotating shaft 36, and the rotating platform 40 is arranged on the top surface of the rotating shaft 36.

[0051] When the transmission assembly 30 is in motion, the transmission shaft 31 drives the first gear 32 to rotate, the first gear 32 drives the second gear 33 to rotate, the second gear 33 drives the rotating shaft 36 to rotate, and finally the rotating shaft 36 drives the rotating platform 40 to rotate in a horizontal plane.

[0052] like Figure 2 and Figure 3 As shown, on one side of the rotary platform 40 ( Figure 2 A positioning block 42 protruding outwards for a distance in the horizontal direction is provided on the left side of the bottom plate 10. The positioning block 42 is used for buffering and positioning the rotating platform 40. Buffering components 60 are provided on opposite sides of the bottom plate 10. The position of the buffering component 60 corresponds to the position of the positioning block 42, so that when the rotating platform 40 is decelerating, the positioning block 42 is connected to the buffering component 60. The buffering component 60 is used for buffering when the rotating platform 40 is decelerating, and can also be used to position the rotating platform 40 when it is stationary.

[0053] like Figure 3 As shown, the buffer assembly 60 includes a buffer bracket 61 disposed on the bottom plate 10, and a buffer 62 extending laterally is disposed on the upper portion of the buffer bracket 61. The buffer 62 can be a spring buffer or a hydraulic buffer. Figure 3 When the buffer 62 contacts the center right end, the head end of the buffer 62 will move a distance toward the tail end to buffer the positioning block 42.

[0054] like Figure 2 and Figure 3 As shown, a locking assembly 70 is also provided on the bottom plate 10, the position of the locking assembly 70 corresponds to the position of the buffer assembly 60, and the locking end of the locking assembly 70 can move toward or away from the direction of the buffer assembly 60. Specifically, when the positioning block 42 is stationary due to the buffering of the buffer assembly 60, the locking assembly 70 moves toward the positioning block 42, pushing the positioning block 42 toward the buffer assembly 60, thereby locking the positioning block 42, that is, locking the rotating platform 40 to prevent the rotating platform 40 from moving, thereby ensuring the positioning accuracy of the rotating platform 40.

[0055] like Figure 3 and 4 As shown, the locking assembly 70 includes a cylinder 71, which is arranged toward the buffer assembly 60. A joint bearing 72 is arranged on the piston rod of the cylinder 71, and a first connecting rod 73 is pivotally connected to the joint bearing 72. The first connecting rod 73 is connected to the locking block 74. The middle part of the locking block 74 is rotatably arranged on the locking seat 75 through the second connecting shaft 741. When the piston rod of the cylinder 71 moves, the locking block 74 will rotate around the second connecting shaft 741, so that the upper end (locking end) of the locking block 74 moves in a circle. A third connecting shaft 76 is arranged at the upper end of the locking block 74, and a locking block 77 is arranged on the outer side of the third connecting shaft 76. The locking block 77 is the locking end of the locking assembly 70. When locking, the locking block 77 abuts against the positioning block 42 to lock the positioning block 42 between the buffer assembly 60 and the locking assembly 70.

[0056] When the device is in use:

[0057] First, the locking assembly 70 is unlocked to release the positioning block 42, and then the motor 20 drives the slewing platform 40 to rotate through the transmission assembly 30, so that the tail end of the detection plate 41 leaves the proximity switch 52. At this time, the controller controls the motor 20 to increase the speed, so that the rotation speed of the slewing platform 40 increases, until the detection plate 41 completely leaves the detection assembly 50 on this side. At this time, the controller controls the motor 20 to keep rotating at a constant speed. When the detection plate 41 moves to the other side and the head end of the detection plate 41 moves to above the proximity switch 52 on this side, the controller controls the motor 20 to start decelerating, so that the rotation speed of the slewing platform 40 decreases, and the detection plate 41 completely leaves the detection assembly 50 on this side. The head end of the plate 41 continues to move forward, so that the detection plate 41 moves to the top of the detection assembly 50. At the same time, the positioning block 42 contacts the buffer assembly 60, and the buffer 62 applies force to the positioning block 42, so that the rotary platform 40 is further decelerated, and the motor 20 gradually drops to 0, and then the locking assembly 70 is actuated, and the cylinder 71 drives the lower end of the locking block 74 to move to the right, so that the locking block 74 will rotate counterclockwise around the second connecting shaft 741, so that the locking end of the locking block 74 moves to the left while the height increases, and finally the locking end of the locking block 74 abuts against the positioning block 42, locking the positioning block 42, and completing the positioning of the rotary platform 40. After the processing of this station is completed, the locking assembly 70 is unlocked, and the motor 20 is reversed to drive the rotary platform 40 back to the previous position.

[0058] In ordinary rotary mechanisms, the rotary platform can only perform simple positioning through cylinders and limit lights, which cannot meet the requirements of precise positioning. In addition, the rotary platform cannot slow down to reach a stable state during the rotation process, which wastes about two seconds of waiting time. In the entire rotation positioning, time efficiency is wasted. The rotary device of the present invention can effectively improve the two points of precise positioning and rotation stability, save rotation time, and achieve the effects of rapid positioning and stable positioning accuracy.

[0059] The above is a description of the embodiments of the present invention. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present invention. Various modifications to these embodiments will be apparent to professionals and technicians in the field. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown in this article, but will conform to the widest range consistent with the principles and novelties disclosed herein.
