[0005] By adopting the above technical solution, the tire unloading robot on the vulcanizer first grabs the two tires and places them on two of the mold adjustment mechanisms of the rear inflation column. The driving cylinder will drive the lifting plate to descend, so that the upper chuck and the lower chuck are gradually approached, so as to lock the tire between the upper chuck and the lower chuck, so that the tire can be inflated. The rear inflation device of the present application can realize automatic locking and inflation of the tire, so as to reduce manpower, shorten the time from the end of vulcanization to the start of inflation of the tire, and better ensure the quality of the tire.

[0007] By adopting the above technical solution, when the upper chuck and the lower chuck lock the tire, the locking nut driven by pneumatic adjustment will rise a certain distance relative to the lower chuck, thereby entering the abutment hole, so that the stability between the upper chuck and the lower chuck can be further improved, and tires of different specifications can also be inflated.

[0008] Optionally, the working surface is provided with a linear guide rail along the vertical direction, and the lifting plate is slidably connected to the linear guide rail.

[0011] By adopting the above technical solution, setting a limit block can limit the descending distance of the lifting plate, thereby preventing the upper chuck from descending excessively, causing the upper chuck and the lower chuck to collide and cause damage, and can extend the service life of the inflation device after the present application.

[0012] Optionally, a safety locking cylinder is provided at the top of the rear inflation column to prevent the upper chuck from accidentally slipping off.

[0013] By adopting the above technical solution, the safety locking cylinder is activated, which can prevent the upper chuck from accidentally slipping, thereby improving safety.

[0014] Optionally, a swivel seat mechanism is provided at the bottom end of the rear inflatable column, and a limit position component is provided on the swivel seat mechanism.

[0015] By adopting the above technical solution, when a vulcanized tire is installed on the vulcanizer, the upper chuck descends to a position matching the tire and is locked before inflation begins. The swivel seat mechanism will drive the rear inflation device to rotate 180 degrees, allowing the other two working surfaces to wait for tire loading. The rear inflation device of the present application can thereby inflate multiple tires and improve work efficiency. The presence of the limit assembly enables the swivel seat mechanism to drive the rear inflation assembly to rotate into place, thereby improving the accuracy of subsequent tire installation.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. The tire unloading manipulator on the vulcanizer first grabs two tires and places them on two mold adjustment mechanisms of the rear inflation column, and the driving cylinder drives the lifting plate to descend, so that the upper chuck and the lower chuck gradually approach each other, so as to lock the tire between the upper chuck and the lower chuck, so that the tire can be inflated. The rear inflation device of the present application can realize automatic locking and inflation of the tire, so as to reduce manpower, shorten the time from the end of vulcanization to the start of inflation of the tire, and better ensure the quality of the tire; 2. When the upper chuck and the lower chuck lock the tire, the locking nut driven by pneumatic adjustment will rise a certain distance relative to the lower chuck, thereby entering the abutment hole, so that the stability between the upper chuck and the lower chuck can be further improved, and tires of different specifications can be inflated.

Four groups of safety locking cylinders 10 are arranged on the surface of the mounting plate 5. Each safety locking cylinder 10 corresponds to a lifting plate 2. A locking hole 202 is opened through the locking plate 201 along the thickness direction for the piston rod of the safety locking cylinder 10 to pass through, so as to lock the lifting plate 2 after it reaches the top, thereby improving safety and stability.

[0025] Reference Figure 1 , Figure 3 and Figure 4 The bottom wall of the mounting frame 3 is provided with an upper chuck 4, and a mold adjustment mechanism 7 is also provided on the working surface 101. The mold adjustment mechanism 7 is sleeved with a lower chuck 8, and the lower chuck 8 corresponds to the upper chuck 4 one by one.
