Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The invention relates to a tire building machine binding device, which comprises a mechanical binding mechanism, wherein the mechanical binding mechanism is arranged on a push disc 4 of a binding seat 1, the binding seat 1 is arranged on a main shaft 18 at one side end of a building drum 2, the push disc 4 is arranged on a linear guide rail II 15 arranged on the binding seat 1 through a sliding seat II, the linear guide rail II 15 is arranged on the binding seat 1, a binding air cylinder 19 is arranged on the binding seat 1 through a cylinder seat, and a cylinder rod extending forwards (towards the building drum 2 direction) of the binding air cylinder 19 is arranged on the push disc 4 through a joint; the mechanical edge covering mechanism comprises anti-wrapping rods 3 uniformly distributed on the circumference between a push disc 4 and a forming drum 2, the rear ends of the rod bodies of the anti-wrapping rods 3 are hinged to corresponding positions of the push disc 4, each hinged part is provided with a limiting structure for positioning the anti-wrapping rods 3 in a horizontal position, the front ends of the rod bodies of the anti-wrapping rods 3 are provided with rolling wheels 5, the central tops of the rod bodies of the anti-wrapping rods 3 are tightly hooped with annular adhesive tapes 10, a plurality of forward sincere hooks 3-1 are arranged on the top of the rod body of the anti-wrapping rod 3 behind the annular adhesive tapes 10 at equal intervals, the bottom of the rod body of each anti-wrapping rod 3 is provided with a plurality of coming wheels 16, and at least one coming wheel 16 is positioned in front of the annular adhesive tapes 10, as shown in fig. 1, 2 and 3.

A hook buckle 6 is arranged corresponding to the front hook 3-1, the hook buckle 6 is arranged on a hook buckle seat 8 through a torsion spring 7, the buckle hooking seat 8 is arranged on the edge covering seat 1, the buckle 6 rotates downwards to a vertical return position under the action of the torsion spring 7 (the lower end of the buckle 6 is a hook, the upper part of the buckle 6 is provided with a top plate extending backwards), the rear side of the buckle 6 at the return position is provided with a thrust mechanism 17, the thrust mechanism 17 comprises a top ring 9 and a thrust plate 11, the thrust plate 11 is arranged on a linear guide rail I12 through a sliding seat I13, the linear guide rail I12 is arranged on the edge covering base 1, the top ring 9 is arranged at the front end of the thrust plate 11, the rear end of the thrust plate 11 is hinged on a cylinder rod extending forwards from the thrust cylinder 14, the cylinder body of the thrust cylinder 14 is mounted on the hemming bed 1 through a cylinder bed, as shown in fig. 1, 2 and 3.

The operation mode of the invention is as follows:

1. during turning, the edge covering cylinder 19 acts to push the push disc 4 forwards, the push disc 4 pushes each turning rod 3 in a radial contraction state to the end face of the forming drum 2, after the foremost hook 3-1 on each turning rod 3 is hooked by the corresponding hook 6, each turning rod 3 which continues to move forwards starts to synchronously and radially expand to turn over the rubber material until the rolling wheel 5 at the front end of each turning rod 3 rolls to the drum face of the forming drum 2, and at the moment, each hook 6 is driven by the corresponding hook 3-1 to rotate to be in an approximately horizontal position.

2. During forward wrapping, the thrust cylinder 14 acts to push the thrust plate 11 forwards, the top ring 9 on the thrust plate 11 acts on the top plate of each hook 6 to push each hook 6 to rotate forwards and upwards to disengage from the hook 3-1, namely, each reverse wrapping rod 3 is unlocked, the edge wrapping cylinder 19 pulls the push disc 4 backwards to retreat, each unlocked reverse wrapping rod 3 synchronously and radially contracts under the action of the annular adhesive tape 10 to roll on the adhesive material to perform forward wrapping operation until each reverse wrapping rod 3 contracts to a horizontal state.

The thrust cylinder 14 acts to pull the thrust plate 11 backwards to return, the top ring 9 releases the top pressure on each hook buckle 6, and each hook buckle 6 rotates backwards and downwards to return to the initial vertical state.

When the invention is used for forward and reverse wrapping, the Foley wheel 16 at the bottom of the reverse wrapping rod 3 moves forwards and backwards on the rubber material and rotates in the circumferential direction.
