DETAILED DESCRIPTION

[0030] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example:

[0032] like Figures 1 to 5As shown, a tire inner liner casting device includes a frame 11, an insulation box 12 is installed above the frame 11, and an insulation chamber 17 is defined in the insulation box 12. A movable door is provided on the side of the insulation chamber 17. A technician opens the movable door and places the tire in the insulation chamber 17, and then closes the movable door to seal the insulation chamber 17 to prevent heat loss. A roller seat 13 is symmetrically provided at the bottom of the insulation chamber 17, and a lower roller 14 is rotatably provided in the roller seat 13. A driving mechanism No. 1 for driving the lower roller 14 to rotate is installed on the frame 11. The driving mechanism No. 1 includes a servo motor 19, which is mounted on the frame 11. A coupling 20 is fixedly connected to the output shaft of the servo motor 19. A drive shaft 32 is provided along the axis of the lower roller 14 on one side. The coupling 20 extends through the insulation chamber 17 and is connected to the rotating shaft 32. In this way, the servo motor 19 can drive the lower roller 14 to rotate. The technician places the tire between the two lower rollers 14 and drives one of the lower rollers 14 to rotate through the servo motor 19, so that the tire starts to rotate, and then drives the other lower roller 14 to rotate.

[0033] After the technician places the tire between the two lower rollers 14, in order to prevent the tire from falling from between the lower rollers 14, a front auxiliary positioning wheel 15 is provided on the front side of the roller seat 13, and a rear support plate 16 is provided on the rear side of the roller seat 13. A No. 2 driving mechanism for driving the rear support plate 16 to move forward and backward is installed on the frame 11. The No. 2 driving mechanism includes a rear adjustable cylinder 21, and the rear adjustable cylinder 21 is installed on the frame 11. The piston rod of the rear adjustable cylinder 21 extends into the insulation chamber 17 and is fixedly connected to the rear support plate 16. In addition, the rear auxiliary positioning mechanism includes two rear positioning auxiliary wheels 31, which are rotatably connected to the rear support plate 16, and the rear positioning auxiliary wheels 31 are both in contact with the side of the tire.

[0034] After the technician places the tire between the two lower rollers 14, one side of the tire contacts the front auxiliary positioning wheel 15. Then the technician uses the rear adjustable cylinder 21 to move the rear abutment plate 16 close to the tire until the rear positioning auxiliary wheel 31 contacts the other side of the tire, thereby ensuring that the tire does not fall off from between the lower rollers 14.

[0035] In addition, the insulation box 12 is slidably provided with rear guide rods 22 on both sides of the rear adjustable cylinder 21, and one end of the rear guide rod 22 extending into the insulation chamber 17 is fixedly connected to the rear support plate 16. The movement direction of the rear support plate 16 is limited by the rear guide rod 22, so that the rear support plate 16 can only move horizontally back and forth, so that the positioning auxiliary wheel 31 can stably contact the side of the tire, preventing the front auxiliary positioning wheel 15 from shaking during the rotation of the tire.

[0036] In order to further fix the position of the tire and to enable the tire to rotate stably, an upper positioning mechanism is installed at the upper end of the insulation box 12, and the upper positioning mechanism includes an upper adjustable cylinder 23, a lifting frame 24 and two upper auxiliary positioning wheels 25. The specific structure of the upper positioning mechanism is: the upper adjustable cylinder 23 is installed at the upper end of the insulation box 12, the lifting frame 24 is located in the insulation chamber 17 and is fixedly connected to the piston rod of the upper adjustable cylinder 23, and the upper auxiliary positioning wheel 25 is rotatably connected to the lower side of the lifting frame 24.

[0037] When the lower end of the tire is limited between the lower roller 14 by the front auxiliary positioning wheel 15 and the rear abutment plate 16, the upper adjustable cylinder 23 drives the lifting frame 24 to move downward until the upper auxiliary positioning wheel 25 abuts against the upper end of the tire. When the tire rotates, the upper auxiliary positioning wheel 25 rotates along with the tire, thereby limiting the upper side of the tire to prevent the tire from shaking during rotation.

[0038] In addition, an upper guide rod 26 that passes through the top of the heat preservation chamber 17 is symmetrically provided at the upper end of the lifting frame 24. When the lifting frame 24 is lifted or lowered, the upper guide rod 26 also slides up and down with it, so that the lifting frame 24 can only move vertically up and down, and increases the structural stability of the lifting frame 24, preventing the lifting frame 24 from shaking when the tire rotates, thereby affecting the connection stability between the upper auxiliary positioning wheel 25 and the tire.

[0039] A pouring machine 18 is provided outside the insulation box 12 and extends into the insulation cavity 17. The nozzle of the pouring machine 18 extends into the inner side of the tire. After the technician fixes the tire, the tire starts to rotate driven by the lower roller 14. The pouring machine 18 sprays glue on the inner curved surface of the tire during the rotation of the tire, thereby achieving the purpose of uniform pouring.

[0040] In order to accelerate the solidification of the glue surface, a constant temperature mechanism is provided in the insulation chamber 17, and the constant temperature mechanism includes a heating wire 27 and a fan 28. The specific structure and connection method of the constant temperature mechanism are as follows: an installation box 29 is installed on the inner wall of the insulation chamber 17, the heating wire 27 is installed in the installation box 29, and the fan 28 is installed on the insulation box 12. The air outlet of the fan 28 extends into the installation box 29, and a plurality of air outlet holes 30 are opened on the side wall of the installation box 29.

[0041] When the pouring machine 18 is performing the pouring operation, the heating wire 27 is powered on for heating, and the fan 28 blows out airflow and blows the hot air in the installation box 29 into the insulation chamber 17 through the air outlet 30, thereby increasing the ambient temperature in the insulation chamber 17 to accelerate the solidification of the glue surface.

[0042] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0043] It should be noted that the front positioning auxiliary wheel 15 and the rear positioning auxiliary wheel 31 in this embodiment are universal wheels, so that they can adapt to tires of different sizes and ensure that they can rotate with the tires without damaging the tire surface.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
