Installation method of two-drum capsule drum reverse capsule

Abstract

The present invention discloses a method for installing a reverse-wrapped capsule for a two-drum capsule drum, comprising the following steps: first, laying down the side drum, then fixing one end of the reverse-wrapped capsule on the bottom side wall of the cylinder body, and then flipping the reverse-wrapped capsule over the bottom position of the side drum; second, installing a booster capsule on the top side wall of the side drum, then vertically hoisting the side drum and inflating the reverse-wrapped capsule through the inflation hole; third, controlling a crane to lower the side drum so that the reverse-wrapped capsule is in place and wraps the side drum in one step, and finally closing the inflation hole. The present invention can greatly save the installation time of the reverse-wrapped capsule. By adopting inflation, the installation can be completed by relying on the free fall of the workpiece, thereby improving the product appearance quality, saving a lot of manpower, and reducing costs. The effect is particularly prominent for large-sized drums.

Description

Technical Field

[0001] The invention relates to the technical field of reverse-packed capsule installation, in particular to a method for installing a double-drum reverse-packed capsule. Background Art

[0002] Bladders are widely used in tire building drums to turn up tire components. Compared to more rigid turn-up devices such as turn-up rollers, bladders have the advantage of having a relatively smooth contact surface, thus leaving less of a mark on the tire component. This is increasingly important as tire components become thinner and more easily damaged.

[0003] The two-drum capsule drum uses a forming drum instead of a carcass drum to bond the rubber material. The forming drum has a triple sleeve structure. In order to achieve the forming function, the reverse capsule needs to fully wrap the side drum, and then the triple sleeve presses the reverse capsule.

[0004] The original method of installing capsules on the two-drum capsule drum is as follows: first, lay the side drum down, then fix one end of the inverted capsule on the bottom side wall of the cylinder body, and then turn the inverted capsule over the bottom position of the side drum; second, install the booster capsule on the top side wall of the side drum, then invert the side drum, manually step on and pull the inverted capsule to completely wrap the side wall of the side drum, and finally, after installing the inverted capsule, press on the triple sleeve to complete the installation of the forming drum.

[0005] However, the above method uses multiple people stepping and pulling, which not only wastes manpower, but also dirtyes the appearance of the parts and affects the quality. Summary of the Invention

[0006] The present invention provides a method for installing a double-drum capsule drum with reversed capsules to solve the problems raised in the above background technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The method for installing the second-drum capsule drum reverse capsule includes the following steps:

[0009] The first step is to lay the side drum down, then fix one end of the reverse capsule on the bottom side wall of the cylinder body, and then turn the reverse capsule over the bottom position of the side drum;

[0010] The second step is to install a booster capsule on the top side wall of the side drum, then vertically lift the side drum and inflate the reverse capsule through the inflation hole;

[0011] The third step is to control the crane to drop the side drum so that the reverse capsule can be put into place in one step to complete the wrapping of the opposite side drum, and finally close the inflation.

[0012] As a further improvement of the present technical solution: in the second step, the side drum is lifted vertically, specifically: the two lifting rings are hooked with a crane hook, and then the side drum is lifted so that the side drum is lifted vertically.

[0013] As a further improvement of this technical solution: the cylinder body is fixedly installed inside the side drum.

[0014] As a further improvement of the present technical solution: in the second step, the inverted capsule is inflated through the inflation hole, specifically: one end of the air supply pipe of the air pump is connected to the inflation hole, and when the air flow enters between the side drum and the cylinder body through the inflation hole, it can then enter between the inverted capsule and the side drum through the air outlet hole on the side drum, and then the inverted capsule can be inflated, so that the bottom of the inverted capsule bulges vertically.

[0015] As a further improvement of the present technical solution: in the third step, the crane is controlled to drop the side drum so that the reverse capsule can wrap the side drum in one step. Specifically, when the crane gradually drops the side drum, the vertically raised bottom of the reverse capsule will first rest against the ground. Then, the reverse capsule will gradually wrap the side drum upwards under the weight of the side drum itself, thereby completing the wrapping of the side drum in one step.

[0016] As a further improvement of the technical solution: after the reverse-wrapping capsule completes the wrapping of the side drum in one step, the side drum is laid down and a triple sleeve is installed on the outside of the reverse-wrapping capsule.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention can greatly save the installation time of the reverse-packed capsule, and the installation can be completed by relying on the free fall of the workpiece by inflation, thereby improving the appearance quality of the product, saving a lot of manpower, and reducing costs. The effect is particularly prominent for large-sized drums.

[0029] See also Figures 1 to 3 In an embodiment of the present invention, a method for installing a two-drum capsule drum reverse capsule includes the following steps:

[0030] The first step is to lay the side drum 4 down, fix the cylinder body 6 inside the side drum 5, and then fix one end of the reverse capsule 3 on the bottom side wall of the cylinder body 6, and then turn the reverse capsule 3 over the bottom position of the side drum 4;

[0031] In the second step, the booster capsule 2 is installed on the top side wall of the side drum 4. Then, the two lifting rings 7 are hooked with the crane hook, and the side drum 4 is lifted so that the side drum 4 is lifted vertically. One end of the air supply pipe of the air pump is connected to the air charging hole 1. When the air flows through the air charging hole 1 and enters between the side drum 4 and the cylinder body 6, it can then enter between the inverted capsule 3 and the side drum 4 through the air outlet 5 on the side drum 4, thereby inflating the inverted capsule 3 and making the bottom of the inverted capsule 3 bulge vertically.

[0032] In the third step, when the crane gradually lowers the side drum 4, the vertically bulging bottom of the inverted capsule 3 will first rest on the ground. Then, under the weight of the side drum 4 itself, the inverted capsule 3 will gradually wrap the side drum 4 upward, thus completing the wrapping of the side drum 4 in one step. Finally, the inflation is turned off, and a triple sleeve is installed on the outside of the inverted capsule 3.
