DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figures 1 to 4 As shown, a tire positioning device for a tire production line comprises: a fixed bracket 1, a conveying roller 2, a first movable baffle 3 and a second movable baffle 4; the fixed bracket 1 is provided with two and the two fixed brackets 1 are symmetrically arranged, and a plurality of conveying rollers 2 are provided, and the plurality of conveying rollers 2 are arranged between the two fixed brackets 1; a first connecting rod 5 is slidably arranged on the fixed bracket 1 along the length direction of the fixed bracket 1, one end of the first movable baffle 3 is hinged on the first connecting rod 5, and the other end is connected to one end of the second movable baffle 4, a second connecting rod 6 is also fixedly arranged on the fixed bracket 1, and a fixing rod 7 is elastically arranged between the side of the second movable baffle 4 away from the other second movable baffle 4 and the second connecting rod 6, and a control rod 8 for controlling the two second movable baffles 4 to move toward each other is arranged below the conveying roller 2 and between the two fixed brackets 1.

[0024] The fixed bracket 1 is used to connect and support the conveying roller 2. The conveying roller 2 rotates to convey the tire. The first movable baffle 3 and the second movable baffle 4 are both used to center the tire. Specifically, the tire first passes through the first movable baffle 3 to move toward the middle. The first movable baffle 3 gradually tilts toward the middle of the conveying roller 2 along the conveying direction, so that the tire gradually moves toward the middle of the conveying roller 2. The first movable baffle 3 and the second movable baffle 4 are hinged. The movement of the second movable baffle 4 is controlled by the control rod 8. That is, the shortest distance between the two first movable baffles 3 is the distance between the two second movable baffles 4. This distance is controlled by the control rod 8. After being guided by the first movable baffle 3, the tire smoothly enters between the two second movable baffles 4. , ensuring that the tire is in the middle of the conveying roller 2; wherein, one end of the first movable baffle 3 is hinged on the first connecting rod 5, and the first connecting rod 5 is slidably set on the fixed bracket 1 along the length direction of the fixed bracket 1, which makes the maximum distance between the two first movable baffles 3 slightly larger than the length of the conveying roller 2, which is convenient for the tire to enter between the two first movable baffles 3 for guidance, and the fixed rod 7 supports the second movable baffle 4, and the two ends of the second movable baffle 4 are provided with fixed rods 7, so that the distance between the two ends of the second movable baffle 4 and the fixed bracket 1 remains the same. The first movable baffle 3 can provide preliminary guidance for the tire on the conveying roller 2, and the two second movable baffles 4 can work together to align the tire on the conveying roller 2 so that it is located at the center of the conveying roller 2, and the two second movable baffles 4 can also be adjusted and moved by the control rod 8, which makes it possible to adjust the distance between the two second movable baffles 4 according to the outer diameter of the tire, without the need to replace the centering equipment, saving production costs.

[0025] Furthermore, if Figure 1 As shown, the fixed bracket 1 is provided with an elongated slide groove 11, and the lower end of the first connecting rod 5 is slidably connected in the elongated slide groove 11. In the process of the control rod 8 controlling the movement of the second movable baffle 4, the angle between the first movable baffle 3 and the second movable baffle 4 changes, and the position of the end of the first movable baffle 3 hinged to the first connecting rod 5 in the horizontal plane also changes. When the distance between the two second movable baffles 4 becomes shorter, the first connecting rod 5 moves toward the direction close to the second connecting rod 6, and vice versa, moves away from the second connecting rod 6.

[0026] Further, the specific structure of the elastic connection of the fixing rod 7 is as follows: Figure 1 and Figure 3As shown, a slide cylinder 61 is fixedly connected to the second connecting rod 6, and a cavity 62 is provided in the slide cylinder 61. A slider 71 is fixed to the end of the fixing rod 7, and the slider 71 is slidably connected in the cavity 62 along a direction perpendicular to the axis of the second connecting rod 6. A compression spring 72 is provided on the outer sleeve of the fixing rod 7, and the compression spring 72 is located in the cavity 62. In a natural state, the elastic force of the compression spring 72 causes the end of the fixing rod 7 to be located in the cavity 62. When the two second movable baffles 4 approach each other, the fixing rod 7 moves accordingly, and the slider 71 slides, so that the compression spring 72 is compressed.

[0027] Furthermore, if Figure 1 and Figure 4 As shown, both ends of the control rod 8 are rotatably connected to the two fixed brackets 1, and the control rod 8 is symmetrically provided with two threaded sections with opposite rotation directions. The bottom end of the second movable baffle 4 is fixedly connected with a control plate 41, and the control plate 41 is provided with a threaded hole, through which the control rod 8 passes, and the two control plates 41 are respectively threadedly connected to the two threaded sections of the control rod 8. One end of the control rod 8 is controlled to rotate by a motor, and when the control rod 8 rotates, the control plates 41 are restricted by the fixed rod 7 connected to the second movable baffle 4, and the two control plates 41 move toward each other on the control rod 8.

[0028] Furthermore, if Figure 3 and Figure 4 As shown, the two second movable baffles 4 are provided with a groove 42 on one side close to each other, and a vertical rod 43 is fixed in the groove 42. A ball 9 is rotatably passed through the vertical rod 43, and the rotation direction of the ball 9 is the same as the conveying direction of the conveying roller 2. When the tire is located between the two second movable baffles 4, the ball 9 will directly contact the tire. Since the ball 9 can rotate freely in the transmission direction, the movement of the tire in the conveying direction is not affected. Further, there are two grooves 42, and the ball 9 is arranged in two rows.

[0029] Similarly, in order to ensure that the first movable baffle plate 3 does not affect the movement of the tire, a ball 9 may also be provided on the first movable baffle plate 3 .

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
