Put the 5 cloth rolls of the inner cloth on the inner cloth hanging shaft, put the 5 cloth rolls of the outer cloth on the outer cloth hanging shaft; then, put the cloth on the inner cloth hanging shaft/outer cloth hanging shaft Pull out the cloth head of the strip, bypass the inner cloth guide wheel group/outer cloth guide wheel group, put it into the inner cloth pulling groove/outer cloth pulling groove, and the cloth head passes through the eccentric inner cloth non-return wheel/eccentric outer cloth stop After returning to the wheel, pull the cloth head of the cloth strip to the front of the inner cloth leading groove/outer cloth leading groove and place it beyond about 1 cm.

Second, turn on the automatic wrapping machine to carry out the inner wrapping operation of the V-belt; the inner wrapping operation of the V-belt is as follows:

1) The first longitudinal traction cylinder drives the moving plate of the first pulling chute and the lining pulling groove on it to move to the right; when the cloth strip on the lining pulling groove just extends into the lower part of the driven wheel, the first longitudinal pulling The traction cylinder stops moving;

2), the platform lifting cylinder drives the cloth wrapping platform to move up, so that the cloth pressing wheel presses the cloth strip 1a and the bottom glue on the V-belt together; then, the first longitudinal traction cylinder drives the first cloth pulling chute moving plate and The lining groove on it moves to the left and resets;

3), the first push cylinder drives the first sliding bracket to move to the right position; then, as shown in Figure 15, the first bracket lifting cylinder drives the first locking wheel rod and the locking wheel group on it to move down to the position, and Make the support bar be located in the give way bayonet of the card position wheel of the card position wheel set, so as to form a cloth limit opening for preventing deviation of the cloth strip between the support bar and the two card position wheels of the card position wheel set, and the cloth The strip is located in the corresponding limit opening of the cloth strip, so that the cloth strip can be effectively prevented from deviation (preventing the deviation of the cloth strip in the up, down, left, and right directions) during the next wrapping process;

4), the driving wheel drive motor is started, and the driving wheel driving motor drives the V-belt to rotate according to the set length. When it turns to the set length, the driving wheel driving motor stops; during this process, the folding wheel cooperates with the folding pressure belt wheel Fold the cloth strips that pass through the folding wheel and the folding pressure pulley to about 90 degrees at the bottom edges of the V-belt; Wrapped on the V-belt, wherein the lower wrapping pulley withstands the V-belt and the cloth strip, and the spring on the wrapping wheel set presses down on the wrapping wheel, which is conducive to tightly sticking the cloth strip to the V-belt.

5), the lifting cylinder of the first cloth pressing block drives the first upper pressing cloth block to move down and press against the first lower pressing cloth block, so as to press the cloth strip tightly between the first upper pressing cloth block and the first lower pressing cloth Between blocks; then, the first telescopic cylinder drives the first blade telescopic platform and the first cutter on it to move along the first upper cutting guide groove and the first lower cutting guide groove, thereby cutting the cloth strip; then, The lifting cylinder of the first cloth-pressing block drives the first upper-pressing cloth block to move up and reset;

Thirdly, the horizontal traction cylinder drives the cloth pulling platform to move in place, so that the outer cloth pulling groove on the cloth pulling platform corresponds to the V-belt installation groove of the driven wheel; then, the outer cloth wrapping operation of the V-belt is carried out, so as to realize Carry out the inner layer wrapping operation and the outer layer cloth wrapping operation of the rubber V-belt without interruption. For the outer layer wrapping operation of the V-belt, refer to the inner layer wrapping operation of the V-belt in the first step.

Fourth, the tensioning cylinder moves to the left to reset, and then the V-belt wrapped by the V-belt is removed to complete a cycle of wrapping process.
