Rolling the embryo onto the tire body is an important process in tire production, which mainly affects the forming quality of the tire.
[0003] In the prior art, generally, an inclined roller or an enclosed rolling member is used to roll the side edge of the embryo onto the tire body, without the need for additional processes to process the side edge of the embryo, improving the production efficiency of the tire. However, when using an inclined roller or an enclosed roller to roll the embryo, the fit with the embryo is poor, and it is easy to form a gap between the embryo and the tire body, reducing the processing accuracy of the embryo. At the same time, the roller is prone to generate a rolling force along the axial direction of the tire body on the circumferential surface of the embryo during rolling, resulting in a gap between the tire body and the embryo, so that the compaction effect of the embryo is poor, reducing the finished product quality of the tire.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0020] like Figures 1 to 3 As shown, this embodiment provides a side rolling device for tire hemming, which is used to roll the tire blank at the end faces of both sides of the rolling drum 200 to the tire body. Specifically, the side rolling device includes a conveying platform 11, a conveying member 12, a supporting platform 13, a driving member 14, a transmission member 15 and a rolling member 16. Specifically, the conveying platform 11 is arranged on the left or right side of the rolling drum 200. In this embodiment, the conveying platform 11 is arranged on the left side of the rolling drum 200 for illustration. The conveying member 12 is at least partially arranged on the conveying platform 11, and the supporting member 163 is at least partially arranged on the conveying member 12. The conveying member 12 can drive the supporting platform 13 to move along the left and right directions of the side rolling device to transport the rolling member 16 to the left side of the rolling drum 200. The driving member 14 is at least partially arranged on the supporting platform 13, and the transmission member 15 is at least partially arranged on the lower side of the supporting platform 13, and the transmission member 15 is connected to the driving member 14. The rolling member 16 is at least partially arranged on the support platform 13, and is connected to the driving member 14 through the transmission member 12, so that the driving member 14 can drive the rolling member 16 to rotate through the transmission member 15. Further, the rolling member 16 includes a connecting plate 161, a buffer member 162, a support member 163, a support rod 164 and a roller 165 from bottom to top. Among them, the connecting plate 161 is connected to the transmission member 15. The support member 163 is connected to the connecting plate 161 through the buffer member 162. The support rod 164 is arranged on the support member 163 in the vertical direction. The roller 165 is arranged on the top of the support rod 164. It can be understood that the support platform 13 and the rolling member 16 each need to be provided with two. In order to roll the tire blank at the front end and the rear end of the rolling drum 200, in this embodiment, only one of the support platforms 13 and the rolling member 16 is taken as an example for description. In order to clearly illustrate the technical solution of the present application, it is also defined as follows Figure 1 The upper side, lower side, left side and right side shown in FIG. Figure 2 Front and rear sides shown.
[0021] With the above settings, when the side rolling device rolls the side of the tire embryo, the rolling member 16 can be moved to the front end face and / or the rear end face of the rolling drum 200 through the transmission member 15 until the rolling drum 200 slightly presses the roller 165, causing the support rod 164 to tilt. At this time, the buffer member 162 provides an upward thrust to the support member 163, prompting the support rod 164 to return to its original position, so that the roller 165 is closely attached to the tire embryo. The tire embryo can be rolled more tightly onto the carcass. In addition, the driving member 14 drives the rolling member 16 to rotate, so that the roller 165 rolls from the circumferential surface of the rolling drum 200 to the end face, which can avoid the generation of a component force in the axial direction of the rolling drum 200 on the side of the tire embryo during rolling, thereby avoiding the generation of a gap between the carcass and the tire embryo and improving the processing accuracy of the side rolling device.
[0022] Specifically, a slide rail 121 is provided on the top of the conveyor member 12 in the front-rear direction of the side rolling device. A slider 122 is provided at the bottom of the support table 13, and the support table 13 is slidably arranged on the slide rail 121 through the slider 122. The distance between the rolling member 16 and the end face of the rolling drum 200 can be adjusted through the slide rail 121, so that the side rolling device is applicable to various models of rolling drums 200, and the rolling accuracy of the roller 165 on the tire embryo is higher.
[0023] Specifically, the transmission member 15 includes a first transmission wheel 151, a second transmission wheel 152, and a transmission belt 153. The driving member 14 is connected to the first transmission wheel 151 to drive the first transmission wheel 151 to rotate. The first transmission wheel 151 is in transmission connection with the second transmission wheel 152 through the transmission belt 153 to drive the second transmission wheel 152 to rotate.

[0024] Such as Figure 4As shown in the figure, an adjusting member 17 is provided on the support table 13. The adjusting member 17 is used to adjust the initial position of the rolling member 16, that is, to adjust the angle between the axial direction of the roller 165 and the axial direction of the rolling drum 200, so that the side rolling device is applicable to rolling drums 200 of different models, improving the versatility of the side rolling device. Specifically, the adjusting member 17 includes a rotating shaft 171 and a rotating part 172. Among them, the rotating shaft 171 is connected to the first transmission wheel 151 and can rotate coaxially with the first transmission wheel 151. The rotating part 172 is sleeved on the rotating shaft 171. Further, a first card slot 1711 is provided on the outer wall of the rotating shaft 171; a threaded hole 1721 is provided on the rotating part 172 in the radial direction of the rotating part 172, and a second card slot 1722 communicating with the threaded hole 1721 is provided on the inner wall.

A rotating handle 1724 is provided on the outer wall of the rotating part 172, and the rotating handle 1724 extends basically in the radial direction of the rotating part 172. When manual adjustment of the first rolling member 16 is required, the relative position of the rotating part 172 and the rotating shaft 171 can be adjusted to align the first card slot 1711 with the second card slot 1722; the bolt 1723 is passed through the threaded hole 1721 and the second card slot 1722 so that at least part of the bolt 1723 is arranged in the first card slot 1711 to make the rotating part 172 and the rotating shaft 171 engage. At this time, the rotating part 172 and the rotating shaft 171 can be rotated by the rotating handle 1724, and the rolling member 16 is driven through the transmission member 15 to adjust the initial position of the rolling member 16.
[0025] Further, the buffer member 162 includes an elastic member 1621 and two buffer pads 1622. The elastic member 1621 extends basically in the vertical direction, and the two ends are respectively connected to the support member 163 and the connecting plate 161, and are used to provide a thrust force to return the support rod 164 to the upright position. The two buffer pads 1622 are sleeved on the elastic member 1621 in the up and down direction. When the elastic member 1621 is bent, at least part of the two buffer pads 1622 abuts to limit the bending angle of the elastic member 1621.

Even further, the rolling member 16 further includes a reset member, and the reset member is arranged between the connecting plate 161 and the support member 163, and the reset member is used to return the support rod 164 to the upright position.
[0026] In summary, the present application provides a side rolling device. When rolling the tire embryo, the rolling drum 200 rotates in the first rotation direction. The conveying member 12 transports the support table 13 to the left side of the rolling drum 200, so that the roller 165 abuts against the rolling drum 200. The roller 165 rotates with the rolling member 16, winds from the circumferential surface of the rolling drum 200 to the front end surface, and rolls the tire embryo. Through the above method, the rolling of the tire edge wrapping mechanism on the tire embryo is more comprehensive and the processing accuracy is higher.
