Description

TECHNICAL FIELD

[0001] The utility model relates to the component structure of tire building machine, concretely is the guide device of giant tire building machine positive and negative package finger type ware pressure system. BACKGROUND

[0002] As the mechanical positive and negative package spring device of all-steel giant tire building machine disclosed in the application patent CN 105365243 A, in the positive and negative package finger type ware pressure device of the existing giant tire building machine, the spring is usually directly pressed on the roller sleeve, the spring is internally provided with a large inner diameter shaft sleeve (namely hollow shaft) and small diameter shaft pin (namely through core shaft), and the through core shaft moves in the hollow shaft along with the expansion and contraction of the finger type rod. This structure has the following two problems: 1, the spring is easy to be stuck and not to rotate, and the rubber is squeezed when the tire body layer is reversed, the steel wire is exposed, and the quality hidden danger is caused; 2, the through core shaft cannot be designed too long due to the arc installation, otherwise the through core shaft will be stuck with the hollow shaft when it is contracted, thus the reverse package height is limited, and the through core shaft is separated from the hollow shaft when the height is too high, the spring jumps out, needs to be repaired, and causes the shutdown. SUMMARY

[0003] In view of the defects of the prior art, the utility model provides a kind of building machine finger type ware guide device, simple and reliable structure, not only can avoid being stuck and not to rotate roller sleeve, also can avoid the problem that spring jumps out when reverse package is too high.

[0004] The utility model achieves the above-mentioned purposes by the following technical solutions:

[0005] The building machine finger type ware guide device includes a roller arranged at the end of the finger type rod and a spring arranged between the front ends of adjacent finger type rods. The rollers of the adjacent finger type rods are respectively provided with a hollow shaft and a core shaft, and the two ends of the core shaft are hingedly connected with a swing shaft, which can swing up and down by being inserted into the hollow shaft. Roller sleeves are installed on both sides of the finger type rod, and the left side of the hollow shaft and the core shaft is provided with a limiting step for clamping the roller sleeve, and the right side of the hollow shaft and the core shaft is clamped with the roller sleeve by a stepped gland. The spring is arranged in the roller sleeve, and the two ends of the spring are respectively abutted with the gland and the limiting step.

[0006] Further, the swing shaft on the left side of the core shaft is hingedly connected with the limiting step of the core shaft, and the swing shaft on the right side of the core shaft is hingedly connected with the core shaft by a welded clamp block.

[0007] Compared with the prior art, the utility model has the following advantages and effects:

[0008] 1. The roller sleeves are installed on both sides of the finger type rod, and the spring is installed in the roller sleeve. The limiting steps on the left and right sides of the hollow shaft and the core shaft and the stepped gland are used to press the spring, which avoids the situation that the spring is stuck and not to rotate due to pressing the roller sleeve;

[0009] 2. Since the pendulum shaft can swing up and down in the hollow shaft, it can be designed to be lengthened. Even if the reverse height reaches the limit, a section of the pendulum shaft will still remain in the hollow shaft, avoiding the problem of the spring jumping out and reducing the number of shutdowns and repairs.

[0012] The present invention will be further described below with reference to the following embodiments, but the present invention is not limited to these embodiments.

[0013] The buckle ring guide device of the forming machine described in this embodiment is as follows: Figure 1 As shown, it includes a roller 2 arranged in the U-shaped fork at the end of the finger-shaped rod 1 and a spring 3 arranged between the front ends of two adjacent finger-shaped rods 1. A hollow shaft 4 and a core shaft 5 are respectively passed through the roller 2 of the two adjacent finger-shaped rods 1. The two ends of the core shaft 5 are hinged with a swing shaft 6 that can swing up and down through a spring pin 10. The swing shaft 6 is staggered and inserted into the hollow shaft 4.

[0014] like Figure 1 As shown, roller sleeves 7 are respectively installed on both sides of the end of the finger-shaped rod 1, and an integrally formed limiting step is provided on the left side of the hollow shaft 4 to clamp and limit the roller sleeve 7 on the left side. The roller sleeve 7 on the right side is clamped by a stepped pressure cover 8 on the right side of the hollow shaft 4. The hollow shaft 4 and the pressure cover 8 are welded together after installation; an integrally formed limiting step is provided on the left side of the core shaft 5 to clamp and limit the roller sleeve 7 on the left side, the swing shaft 6 on the left side of the core shaft 5 is hinged to the limiting step, and the roller sleeve 7 on the right side is clamped by a stepped pressure cover 8 on the right side of the core shaft 5. The swing shaft 6 on the right side of the core shaft 5 is hinged to the core shaft 5 through a clamping block 9. After the core shaft 5 and the pressure cover 8 are installed in place, the core shaft 5 and the clamping block 1 are welded together to clamp the pressure cover 8.

[0015] like Figure 1 As shown, the spring 3 is placed in the roller sleeves 7 on the left and right sides, with its left end abutting against the pressure cover 8 on the side of the hollow shaft 4, and its right end abutting against the limiting step of the core shaft 5.
