Description

Technical Field

[0001] The utility model relates to the technical field of tire rubber processing, in particular to an apex rubber exhaust pressing device. Background Art

[0002] Tire bead apex is the primary filler in the tire bead, providing support and transitional support for the sidewall, improving driving stability, steering, and comfort. As the filler material on the bead, the bead apex is crucial for mitigating bead impact and preventing air ingress during molding, and typically requires degassing during production.

[0003] In the current apex production process, two compounding extruders first extrude the apex components, which are then cooled and weighed before being compounded with a thin film. During the compounding process, the air at the joints should be exhausted and the parts should be tightly fitted. Pressing rollers are often used to press and exhaust the air. However, there are some functional deficiencies in actual use, leaving room for improvement. For example, the distance between the pressing rollers is fixed, and the pressing requirements for tire apex rubbers of different specifications are different. This results in insufficient applicability and a lack of a function to facilitate adjustment of pressing specifications.

[0004] Now, a new apex adhesive exhaust pressing device is proposed to solve the above problems. Utility Model Content

[0023] The outer diameters of the first optical axis 2 and the second optical axis 3 are the same, the sizes of the first ball screw 4 and the second ball screw 6 are the same, the inner diameter of the linear bearing slider 10 is adapted to the outer diameters of the first optical axis 2 and the second optical axis 3, and the linear bearing slider 10 can slide left and right along the outside of the first optical axis 2 and the second optical axis 3. The external threads of the first ball screw 4 and the second ball screw 6 match the internal threads of the screw bearing slider 11. The specifications of the first mounting plate 8 and the second mounting plate 9 are consistent, which facilitates distance adjustment according to the specifications of the apex rubber;

[0024] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, by rotating the first hand wheel 5 and the second hand wheel 7, the first ball screw 4 and the second ball screw 6 can be rotated. By cooperating with the screw bearing slider 11, the first mounting plate 8 and the second mounting plate 9 can be pulled to slide along the first optical axis 2 and the second optical axis 3 through the linear bearing slider 10, thereby changing the distance between the two groups of multi-piece pressure rollers 16.

[0025] Embodiment 2: A cylinder 12 is installed at the middle position of one end of the first mounting plate 8 and the second mounting plate 9 far from the first optical axis 2. Two sets of fixing rings 13 are fixedly connected to both sides of the bottom of one end of the first mounting plate 8 and the second mounting plate 9 far from the first optical axis 2.
