AI Technical Summary
Existing tire production equipment is prone to damage the tire pattern and shoulder parts during the rebirth process, especially due to the large differences in tire patterns, the angle and position adjustment during rebirth are poor.
A rear-inflating and removable device for vulcanization machine is designed, using the threads of the ball screw and the opposite direction of the removable cylinder. The position of the removable cylinder is adjusted through the ball screw adjustment handle to ensure that the nylon guard plate contacts the sidewall of the tire during removable and avoids damage to the tire.
It realizes flexible adjustment of the rebirth position, meets the rebirth needs of tires of different specifications, and avoids damage to the tread pattern and shoulder parts.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, and particularly to a post-inflation tire removal device for a vulcanizer. Background Art
[0002] As is well known, during the process of manufacturing tires, the tires after high-temperature vulcanization will deform during the gradual cooling process at normal temperature, seriously affecting the quality of the tires. To avoid this situation, usually the tires coming out after high-temperature vulcanization are placed on the post-inflation shaping device to gradually cool down to normal temperature, and then the shape of the tires will remain unchanged. When unloading the tires after inflation and shaping, the problem of sticking to the chuck is likely to occur. There is a certain viscosity between the tire and the chuck, and an external device is needed to separate the chuck from the tire. Some tire factories use an adjustable-position single-cylinder tire pushing device. When the post-inflation is opened, the tire removal cylinder acts to separate the tire from the chuck. It is found in on-site use that this device has disadvantages. Due to the large difference in tire patterns, poor adjustment of the angle and position during tire removal will cause damage to the tire tread blocks and shoulder parts. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a post-inflation tire removal device for a vulcanizer, which can meet the requirement of tire removal while avoiding damage to the tires.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a post-inflation tire removal device for a vulcanizer is provided with a post-inflation frame. Its feature is that a post-inflation base is fixed at the top of the post-inflation frame. A chuck driving oil cylinder and a guide rail base are installed on the post-inflation base. The lower end of the cylinder rod of the chuck driving oil cylinder is installed with an upper inflation chuck. A linear guide rail is fixed on the guide rail base. Guide rail sliders in sliding fit are installed on the left and right sides of the linear guide rail respectively. A tire removal cylinder is installed at the lower part of each guide rail slider. The lower end of the telescopic rod of the tire removal cylinder is installed with a nylon guard plate. A ball screw is in threaded fit with the cylinder bodies of the left and right tire removal cylinders, and the ball screw is provided with threads in opposite directions at the positions of the cylinder bodies of the left and right tire removal cylinders. A lower inflation chuck fixing seat is fixed at the bottom of the post-inflation frame, and a lower inflation chuck is installed on the lower inflation chuck fixing seat.
[0005] The end of the said ball screw is connected with a ball screw adjusting handle.
[0006] The beneficial effect of the utility model is that the tire removal position can be adjusted according to the different diameters of the inflation chucks to meet the tire removal requirements of different specifications, and it will not cause damage to the tread pattern and shoulder parts of the tire. Brief Description of the Drawings
[0007] The following further explains the utility model in conjunction with the drawings and embodiments.
[0008] Figure 1 Structure schematic diagram of the utility model.
[0009] In the figure, 1. Rear inflation frame, 2. Chuck driving oil cylinder, 3. Rear inflation base, 4. Guide rail base, 5. Linear guide rail, 6. Ball screw adjusting handle, 7. Ball screw, 8. Demolding cylinder, 9. Nylon guard plate, 10. Upper inflation chuck, 11. Lower inflation chuck fixing seat, 12. Guide rail slider, 13. Lower inflation chuck. Detailed implementation mode
[0010] In the figure, the utility model is provided with a rear inflation frame 1. A rear inflation base 3 is fixed at the top of the rear inflation frame 1. A chuck driving oil cylinder 2 and a guide rail base 4 are installed on the rear inflation base 3. The lower end of the cylinder rod of the chuck driving oil cylinder 2 is installed with an upper inflation chuck 10. A linear guide rail 5 is fixed on the guide rail base 4. Guide rail sliders 12 in sliding fit are respectively installed on the left and right sides of the linear guide rail 5. A demolding cylinder 8 is installed at the lower part of each guide rail slider 12. The lower end of the telescopic rod of the demolding cylinder 8 is installed with a nylon guard plate 9. The ball screw 7 is in threaded fit with the cylinder bodies of the left and right demolding cylinders 8, and the ball screw 7 is provided with threads in opposite directions at the positions of the cylinder bodies of the left and right demolding cylinders 8. The end of the ball screw 7 is connected with a ball screw adjusting handle 6. A lower inflation chuck fixing seat 11 is fixed at the bottom of the rear inflation frame 1. A lower inflation chuck 13 is installed on the lower inflation chuck fixing seat 11.
[0011] The utility model operates according to the set position of the chuck driving oil cylinder 2, so that the upper inflation chuck 10 and the lower inflation chuck 13 are closed to inflate the tire. After the inflation is completed, the upper inflation chuck 10 moves upward through the connection of the cylinder rod of the chuck driving oil cylinder 2, and at the same time, the telescopic rod of the demolding cylinder 8 moves downward to complete the separation of the upper inflation chuck 10 from the inflated tire. The position of the demolding cylinder 8 can be adjusted according to the size of the upper inflation chuck 10 to meet the requirements for the separation of the upper inflation chuck 10 from the inflated tire of different specifications. The specific adjustment method is that since the ball screw 7 is provided with threads in opposite directions at the positions of the cylinder bodies of the left and right demolding cylinders 8, when adjusting through the ball screw adjusting handle 6, the two demolding cylinders 8 act simultaneously and perform opening and closing actions synchronously. The demolding cylinder 8 is connected with a guide rail slider 12, so as to drive the guide rail slider 12 to move left and right on the linear guide rail 5. A nylon guard plate 9 is installed on the demolding cylinder 8. When performing the demolding action, the nylon guard plate 9 contacts the side part of the tire and will not damage the tire.
