Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cylinder booster devices, and more specifically to a reverse capsule double-stroke cylinder booster device. Background Art
[0002] A radial tire is a new type of tire in which the carcass cords are arranged in the meridian direction and the buffer layer is tightly clamped on the carcass by the circumferentially arranged or nearly circumferentially arranged cords. During production and processing, it is mostly produced and processed by a radial passenger tire secondary forming machine. One-stage forming generally involves a process of fitting the carcass (liner, cord), positive packing, bead placement, reverse packing, fitting the sidewalls, positive packing rolling and releasing the carcass tube on a carcass drum, among which the bladder reverse packing process is an indispensable operating step.
[0003] Insufficient existing technology: Traditional capsule reverse packing devices generally have two capsule cylinders with smaller diameters symmetrically arranged on both sides of the main shaft. Before a drum is fitted with the inner liner, the capsule cylinder pushes the capsule seat to the inner edge of the lower side of the fitting drum, and the fitting drum begins to fit the tire body. Then, after the buckle ring is properly packed, the capsule begins to be inflated and reversed. At the same time, the capsule reverse packing push plate extends out and starts to push the capsule for reverse packing. At this time, the capsule slide seat is forced to retreat due to the reaction force of the internal pressure of the capsule and the small cylinder diameters (generally DN40) of the two capsule cylinders on both sides, and the thrust is small. Traditional molding devices have two capsules. The capsule slide seat anti-retraction device locks the capsule slide seat to prevent it from retreating; the capsule anti-retraction device is often imperfect, causing the turn-up seat to retreat and poor turn-up effect; at the same time, when a section of the bonding drum is bonding the carcass cord, the carcass cord is often much wider than the width of the bonding drum, and there is no support on the edge of the bonding drum (the diameter of the traditional capsule seat when not inflated is smaller than the diameter of a section of the bonding drum, although the capsule seat can reach the lower edge of the section when bonding a section of the drum), the carcass cord will overhang on both sides, and bubbles will be generated after bonding or turning up, resulting in defective products.

[0010] Furthermore, the first stroke of the cylinder mechanism is 110 mm, and the first stroke of the cylinder mechanism is 40 mm.
[0011] Technical effects and advantages of the utility model:
[0012] 1. The utility model makes the cylinder mechanism, the capsule slide and the capsule body move laterally to the working position through the automatic telescopic rod extension and retraction. The cylinder mechanism operates to make the capsule slide connected to the front end of the cylinder mechanism extend 110mm to the edge of a bonding drum (8-10mm away from the edge of the drum). The reverse capsule is basically flush with the bonding drum, that is, 5-8mm slightly lower than the drum. At this time, the carcass cord is bonded. Due to the support of the reverse capsule, the edge of the cord will not droop. After the carcass cord is bonded, the second stroke of the cylinder mechanism extends 40mm, and the front end of the capsule slide extends into the lower edge of the bonding drum by about 28-30mm, thereby realizing the reverse packaging process of the capsule. After the reverse packaging capsule is inflated, the reverse packaging capsule push plate pushes the capsule in the reverse packaging process. Due to the reaction force, the original capsule cylinder will retreat, but because the cylinder body of the cylinder is relatively large, the cylinder piston will not retreat, thereby solving the problem of insufficient reverse height caused by the reverse locking of the reverse packaging capsule.
[0013] 2. The utility model fixes the cylinder mechanism on the surface of the diamond plate through four cylinder pull rods passing through the second stroke outer cylinder body, the middle fixed plate, the first stroke outer cylinder body and the diamond plate, thereby completing the installation and fixation of the cylinder mechanism, and inflates the interior of the capsule through the second capsule inflation hole and the first capsule inflation hole.
