Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire processing technology, and particularly relates to a side rolling device for tire blank forming. BACKGROUND

[0002] The tire blank is wrapped outside the tire body to prevent the tire body from being mechanically damaged, and can transmit the traction and braking force of the vehicle and buffer the impact of the tire during driving. Rolling the tire blank to the tire body is an important process in tire production, which dominates the forming quality of the tire.

[0003] In the prior art, an inclined roller or a surrounding rolling piece is generally used to roll the side edge of the tire blank to the tire body, without the need for additional processes to process the side edge of the tire blank, thereby improving the production efficiency of the tire. However, when the inclined roller or the surrounding roller is used to roll the tire blank, the roller partially fits the tire blank, which is easy to cause a gap between the tire blank and the tire body, thereby reducing the processing accuracy of the tire blank. At the same time, the roller is easy to generate a rolling force in the axial direction of the tire body on the circumferential surface of the tire blank during rolling, which causes a gap between the tire body and the tire blank, thereby reducing the compaction effect of the tire blank and the finished product quality of the tire.

[0019] The technical solutions in the embodiments will be described clearly and completely in combination with the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0020] As Figures 1 to 3As shown, the embodiment provides a side rolling device for tire blank forming. The side rolling device comprises a conveying table 11, a conveying member 12 and a rolling assembly 13. Specifically, the conveying table 11 is arranged at the left side or the right side of the rolling drum 200. In this embodiment, the conveying table 11 is arranged at the left side of the rolling drum 200. The conveying member 12 is arranged at least partially on the conveying table 11. Along the front-rear direction of the side rolling device, the conveying member 12 is provided with a first support table 14 and a second support table 15. The first support table 14 is provided with a first driving member 141 and a first transmission member 142; the second support table 15 is provided with a second driving member and a second transmission member. More specifically, the rolling assembly 13 comprises a first rolling member 131 and a second rolling member 132. The first rolling member 131 is arranged on the first support table 14, and the second rolling member 132 is arranged on the second support table 15. The conveying member 12 can drive the first support table 14 and the second support table 15 to move along the left-right direction, so as to control the distance between the first rolling member 131 and the second rolling member 132 and the rolling drum 200. Further, the first rolling member 131 is in transmission connection with the first driving member 141 through the first transmission member 142, and the second rolling member 132 is in transmission connection with the second driving member through the second transmission member. The first driving member 141 can drive the first rolling member 131 to rotate, and the second driving member can drive the second rolling member 132 to rotate. The first rolling member 131 is provided with a first roller 1311, and the second rolling member 132 is provided with a second roller 1321. The first roller 1311 and the second roller 1321 are used for rolling the tire blank. For the purpose of clearly describing the technical solutions of the present application, the upper side, the lower side, the left side and the right side are defined as shown in Figure 1 The front side and the rear side are defined as shown in Figure 2

[0021] When rolling the tire blank, the rolling drum 200 rotates along the first rotation direction T1. The conveying member 12 carries the first support table 14 and the second support table 15 to the left side or the right side of the rolling drum 200 along the left-right direction, so that the first roller 1311 and the second roller 1321 are respectively attached to the tire blank on the circumferential surface of the rolling drum 200. The first driving member 141 drives the first rolling member 131 to rotate along the second rotation direction T2, so that the first roller 1311 is rolled from the circumferential surface of the rolling drum 200 to the front end surface, and the tire blank is rolled. The second driving member drives the second rolling member 132 to rotate along the third rotation direction T3, so that the second roller 1321 is rolled from the circumferential surface of the rolling drum 200 to the rear end surface, and the tire blank is rolled.

[0022] ​Through the above arrangement, when the side rolling device rolls the side of the tire body, the first roller 1311 and the second roller 1321 adopt the rolling mode from the tire body circumferential surface to the two end surfaces, which improves the adhesion of the first roller 1311 and the second roller 1321 to the tire body, reduces the possibility of gap between the tire body and the tire body, and improves the processing precision of the tire body. At the same time, it can avoid the rolling force in the axial direction of the rolling drum 200 on the circumferential surface of the tire body, and can better compact the tire body to the tire body, and improve the finished product quality of the tire.

[0023] Specifically, the top of the conveying member 12 is provided with a sliding rail 121 in the axial direction of the rolling drum 200. The first support table 14 and the second support table 15 are respectively provided with sliding blocks 122 at the bottom, and the first support table 14 and the second support table 15 are both slidingly arranged on the sliding rail 121 through the sliding blocks 122. The first roller 1311 can adjust the distance from the front end surface of the rolling drum 200 through the sliding rail 121, and the second roller 1321 can adjust the distance from the rear end surface of the rolling drum 200 through the sliding rail 121, so that the side rolling device is suitable for various types of rolling drums 200, and the rolling precision of the first roller 1311 and the second roller 1321 on the tire body is higher.

[0024] Specifically, the first transmission member 142 includes a first transmission wheel 1421, a second transmission wheel 1422 and a transmission belt 1423. The first driving member 141 is connected with the first transmission wheel 1421 to drive the first transmission wheel 1421 to rotate. The first transmission wheel 1421 is in transmission connection with the second transmission wheel 1422 through the transmission belt 1423 to drive the second transmission wheel 1422 to rotate. The first rolling member 131 is connected with the second transmission wheel 1422 and rotates coaxially with the second transmission wheel 1422.

[0025] As Figure 4As shown, the first support table 14 is provided with an adjusting member 143, which is connected with the first transmission member 142. The adjusting member 143 is used to adjust the initial position of the first rolling member 131, i.e. to adjust the included angle between the axial direction of the first roller 1311 and the axial direction of the rolling drum 200, so that the side rolling device is suitable for different models of the rolling drum 200, and the versatility of the side rolling device is improved. Specifically, the adjusting member 143 includes a rotating shaft 1431 and a rotating part 1432. The rotating shaft 1431 is connected with the first transmission wheel 1421 and can rotate coaxially with the first transmission wheel 1421. The rotating part 1432 is sleeved on the rotating shaft 1431. Further, the outer wall of the rotating shaft 1431 is provided with a first clamping groove 1431a; the rotating part 1432 is provided with a threaded hole 1432a in the radial direction of the rotating part 1432, and the inner wall is provided with a second clamping groove 1432b in communication with the threaded hole 1432a. A bolt 1432c is arranged in the threaded hole 1432a. The outer wall of the rotating part 1432 is provided with a rotating handle 1432d, which extends substantially in the radial direction of the rotating part 1432. When manual adjustment of the first rolling member 131 is needed, the relative position of the rotating part 1432 and the rotating shaft 1431 can be adjusted so that the first clamping groove 1431a and the second clamping groove 1432b are opposite; the bolt 1432c is passed through the threaded hole 1432a and the second clamping groove 1432b, and the bolt 1432c is at least partially arranged in the first clamping groove 1431a, so that the rotating part 1432 and the rotating shaft 1431 are clamped. At this time, the rotating handle 1432d can be used to rotate the rotating part 1432 and the rotating shaft 1431, and the first rolling member 131 is adjusted by the first transmission member 142 to adjust the initial position of the first rolling member 131.

[0026] It can be understood that the second support table 15 has substantially the same structure as the first support table 14, and the two are correspondingly arranged on the slide rail 121, which will not be described here.

[0027] As shown in the drawings, Figures 1 to 3 The first rolling member 131 further includes a connecting plate 1312, a buffer member 1313, a support member 1314, and a support rod 1315. The connecting plate 1312 is connected with the first transmission member 142. The support member 1314 is connected with the connecting plate 1312 through the buffer member 1313, the support rod 1315 is arranged on the support member 1314 in the vertical direction, and the first roller 1311 is arranged on the top of the support rod 1315. When rolling the tire blank at the front end surface of the rolling drum 200, the conveying member 12 conveys the first support table 14 towards the rolling drum 200 until the tire blank slightly presses the first roller 1311, so that the support rod 1315 is inclined. At this time, the buffer member 1313 provides an upward thrust to force the support rod 1315, so that the first roller 1311 can closely contact the tire blank, and the tire blank can be more tightly rolled to the tire body, improving the processing precision of the side rolling device.

[0028] Further, the buffer 1313 comprises an elastic member 1313a and two buffer pads 1313b. The elastic member 1313a extends substantially in the vertical direction, and is connected with the support member 1314 and the connecting plate 1312 at two ends respectively, for providing a pushing force to straighten the support rod 1315. The two buffer pads 1313b are sleeved on the elastic member 1313a in the up-down direction, and at least partially abut when the elastic member 1313a is bent, so as to limit the bending angle of the elastic member 1313a. The buffer pads 1313b are made of rubber material, so as to reduce the abrasion between the two buffer pads 1313b. Further, the first rolling member 131 further comprises a reset member 1316, which is arranged between the connecting plate 1312 and the support plate, and is used to straighten the support rod 1315.

[0029] It can be understood that the structure of the second rolling member 132 is substantially the same as that of the first rolling member 131, and the two are arranged corresponding to each other, which will not be described herein again.

[0030] In summary, the side rolling device provided by the present application is used to roll the tire blank, and the rolling drum 200 rotates in the first rotation direction T1. The conveying member 12 conveys the first support table 14 and the second support table 15 to the left side of the rolling drum 200, so that the first roller 1311 and the second roller 1321 abut the rolling drum 200 respectively. The first roller 1311 rotates in the second rotation direction T2, and is rolled from the circumferential surface of the rolling drum 200 to the front end surface, for rolling the tire blank; the second roller 1321 rotates in the third rotation direction T3, and is rolled from the circumferential surface of the rolling drum 200 to the rear end surface, for rolling the tire blank. Through the above-mentioned manner, the side rolling device has higher processing precision for the tire blank.

[0031] The above description of the embodiments of the present application enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
