DETAILED DESCRIPTION

[0014] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Reference Figure 1-Figure 4As shown, a tire silent cotton pressing device comprises a base plate 1 and a tire 24, pillars 2 are fixedly connected at the four corners of the upper surface of the base plate 1, a workbench 3 is fixedly connected to the upper surface of the pillar 2, a circular hole 5 is penetrated in the center of the upper surface of the workbench 3, a motor 4 is fixedly connected at the center of the upper surface of the base plate 1, a turntable 6 is fixedly connected to the output end of the motor 4, the turntable 6 is rotatably connected in the circular hole 5, the turntable 6 is rotated by the rotation of the motor 4, thereby driving the rotation of the tire 24 on the turntable 6, a driven gear 14 is fixedly connected to one end of the bidirectional screw rod 10, a servo motor 15 is fixedly connected to the upper surface of one of the bearing seats 9, a driving gear 16 is fixedly connected to the output end of the servo motor 15, the driving gear 16 is meshed with the driven gear 14, a square groove 8 is opened on the upper surface of the turntable 6, bearing seats 9 are symmetrically fixedly connected to the upper surfaces of the square groove 8 at both ends, a bidirectional screw rod 10 is rotatably connected in the bearing seat 9, and the two ends of the bidirectional screw rod 10 are The end is threadedly connected with a moving block 11, and the two ends of the upper surface of the moving block 11 are symmetrically fixedly connected with a rotating shaft 12, and the rotating shaft 12 is slidably connected with a roller 13. When the servo motor 15 works, it will drive the moving block 11 on the bidirectional screw rod 10 to move relatively, so that the roller 13 on the moving block 11 clamps the tire 24, so that the tire 24 is relatively fixed on the turntable 6. The side of the bottom plate 1 is fixedly connected with an L-shaped plate 7, and the lower surface of the L-shaped plate 7 is fixedly connected with a cylinder 18. The output end of the cylinder 18 is fixedly connected with a mounting plate 19, and the lower surface of the mounting plate 19 is fixedly connected with a bidirectional cylinder 20. The output end of the bidirectional cylinder 20 is fixedly connected with a U-shaped plate 21, and the two sides of the U-shaped plate 21 are fixedly connected with a short shaft 22, and the short shaft 22 is rotatably connected with a pressing roller 23. By setting the bidirectional cylinder 20, when the bidirectional cylinder 20 moves symmetrically, the silent cotton can be symmetrically pressed, and the silent cotton in the tire can be pressed more fully.

[0016] A plurality of bull's eye universal wheels 17 are fixedly connected to the upper surface of the turntable 6, and the tire 24 is located above the turntable 6. The tire 24 is in contact with the bull's eye universal wheels 17. By providing the bull's eye universal wheels 17, the friction between the tire 24 and the turntable 6 can be reduced, and then the processed tire can be pushed out through the movement of the tire behind, thereby realizing the function of automatic loading.

[0017] When the tire 24 runs onto the turntable 6, the servo motor 15 is started, and the servo motor 15 drives the driving gear 16 to rotate. Since the driving gear 16 and the driven gear 14 are meshed, the driven gear 14 also rotates accordingly, and the driven gear 14 drives the bidirectional screw rod 10 to rotate. The two moving blocks 11 move relative to each other under the rotation of the bidirectional screw rod 10, thereby driving the rollers 13 on the moving blocks 11 to move. When the rollers 13 on both sides clamp the tire 24, the servo motor stops working, and the cylinder 18 is started at this time. The cylinder 18 drives the bidirectional cylinder 20 to move downward, and when the bidirectional cylinder 20 moves to the center of the tire, the servo motor 18 stops working. The two-way cylinder 20 is moved to make the output end of the two-way cylinder move relatively. When the pressure roller 23 on the two-way cylinder 20 contacts the silent cotton, the motor 4 is started. At this time, the motor 4 will drive the tire 24 to rotate, so that the tire 24 and the pressure roller 23 move relative to each other. Under the action of the pressure roller 23, the pressing function of the silent cotton is realized. By setting the bull's eye universal wheel 17, the friction between the tire 24 and the turntable 6 can be reduced, and then the processed tire can be pushed out through the movement of the rear tire, thereby realizing automatic loading. By setting the two-way cylinder, the silent cotton can be pressed symmetrically, and the pressing of the silent cotton in the tire can be more substantial.
