Description

Adjustable rear inflating device of tyre vulcanizer

Technical Field

The utility model relates to a tire design vulcanizer part mechanism specifically is a back aerating device with adjustable tire vulcanizer.

Background

The size range of vulcanized tires produced by the single-mode tire vulcanizing machine is generally large, the middle roller of a rear inflating device in the vulcanizing machine is often required to be adjusted, specifically, the position of the middle roller is changed and the length of the middle roller is changed (the vulcanizing machine is provided with two sets of middle rollers with different lengths), and the position of a chain is required to be adjusted because the power of the middle roller is driven by a chain wheel driven by a motor.

In the prior art, the middle roller has no quick adjusting mode, can only be adjusted by changing the position of the chain wheel of the middle roller, and needs to adjust the positions of all the chain wheels of the middle roller, because the transmission chain wheel is an integral double-row chain wheel, the assembly and disassembly are more complicated, and the operation efficiency of the rear inflating device is greatly reduced.

When the outer diameter span of the vulcanized tire is large, only another set of intermediate rollers can be replaced, so that the replacement is more time-consuming, and the added intermediate rollers also cause the increase of equipment cost.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims to solve the technical problem that a rear inflation device with adjustable tire vulcanizer that only needs one set of intermediate roll mechanism to adjust has been proposed.

Rear inflating device with adjustable tire vulcanizer that can solve above-mentioned technical problem, its technical scheme is different including locating the middle roller mechanism between front roller mechanism and the rear roller mechanism:

1. the middle roller mechanism comprises a left middle roller frame and a right middle roller frame which are symmetrical, the left middle roller frame and the right middle roller frame are slidably mounted on a left track frame and a right track frame, a fastener for fixing the sliding position is arranged between each middle roller frame and the track frame, each middle roller frame is provided with a front carrier roller, a middle carrier roller and a rear carrier roller, and a duplex chain wheel is fixedly mounted on an overhanging roller shaft of the middle carrier roller.

2. One row of chain teeth of the double-row chain wheel are connected with a chain wheel fixedly arranged on an extended roll shaft of the front carrier roller through a chain I, the other row of chain teeth of the double-row chain wheel is connected with a chain wheel I fixedly arranged on an extended roll shaft of the rear carrier roller through a chain II, the chain wheel II fixedly arranged on the outer side of the chain wheel I after the position of the extended roll shaft of the rear carrier roller is slidably adjusted is connected with a chain wheel III fixedly arranged on an extended end on the same side of the transmission shaft after being slidably adjusted through a chain III.

In order to adapt to the receiving and taking of small-sized vulcanized tires, the left and right middle roller frames synchronously adjust the positions in opposite directions to shorten the distance.

In order to adapt to the receiving and taking of large-size vulcanized tires, the positions of the left and right middle roller frames are synchronously adjusted back to increase the distance.

Further, the transmission shaft is arranged on a rear roller frame below a rear roller set of the rear roller mechanism and connected with a motor arranged on the rear roller frame through a speed reducing mechanism.

The utility model has the advantages that:

the utility model discloses back aerating device specially adapted single mode tire vulcanizer with adjustable tire vulcanizer, its advantage embodies:

1. the efficiency is improved, and the cost is reduced. After the device is adopted, a second set of intermediate roll mechanism does not need to be additionally arranged, and the time and the material cost for replacing the intermediate roll mechanism are saved.

2. Simple structure and convenient adjustment. When the position of the middle roller frame is adjusted, the position of the chain wheel on the lengthened overhanging roller shaft only needs to be adjusted to be aligned forwards and backwards, and the time for adjusting the chain is greatly reduced.
