[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-4 As shown, the present invention discloses an internal support gripper for loading and unloading of a retreaded tire laminating machine, comprising a main body 1, a servo motor 2, a reducer 3, a coupling 4, a clamping column 5, a slide 6, and a lead screw 7. The servo motor 2, the reducer 3, and the coupling 4 are connected in sequence, the coupling 4 is connected to the lead screw 7, both ends of the lead screw 7 are provided with external threads with opposite thread rotation directions, the external threads are respectively connected with nuts to form a lead screw nut structure, the nuts are respectively fixedly connected with the slide 6, the slide 6 is respectively provided at both ends of the bottom of the main body 1, the slide 6 can slide longitudinally on the main body 1, and the main body 1 is provided with a longitudinal guide Rail, the slide 6 slides along the longitudinal guide rail driven by the nut, and the slides 6 on both sides move toward or away from each other, the clamping column 5 is fixedly connected to the bottom of the slide 6, and two left and right clamping columns 5 are arranged on the same slide 6, and the center of the clamping column 5 faces the inner side of the main body 1; the outer side of the clamping column 5 is arc-shaped, and an anti-drop block 9 is arranged at the bottom of the clamping column 5, and the anti-drop block 9 extends outward from the bottom of the clamping column 5 to form an inclined slope 8; the clamping column 5 is driven by the left and right slides 6 to move from the center to both sides at the same time to tighten the inner circle of the tire, and the anti-drop block 9 prevents the tire from accidentally falling during transportation.

[0019] The servo motor 2 of the present invention drives the lead screw 7 to rotate through the reducer 3 and the coupling 4. The rotation of the lead screw 7 drives the slide 6 to move toward or away from each other, and the clamping column 5 grabs the tire.
