The following describes the specific principles of use of the present utility model to facilitate an understanding of the present utility model:

firstly, when the machine is started, the motor 10 drives the second rotating shaft 9 and the lower pressing cylinder 3 to synchronously rotate through the synchronous wheel assembly 7, so that a workpiece can be driven to pass through the film pressing mechanism.

As shown in fig. 1-3, when the position of the upper pressing cylinder 2 needs to be adjusted upwards, the worm 61 can be rotated forwards, so that the worm 61 is utilized to drive the worm wheel 62 and the first positioning column 65 to rotate downwards, and since the worm wheel 62 is movably connected to the first rotating shaft 8 and the cam 63 is fixedly connected to the first rotating shaft 8, when the worm wheel 62 rotates downwards, the first positioning column 65 simultaneously pushes the second positioning column 66 to move downwards, and simultaneously drives the cam 63, the first rotating shaft 8 and the upper pressing cylinder 2 to rotate downwards; when the outer end of the cam 63 contacts with the catch wheel 64, the first rotating shaft 8 is gradually lifted up due to the shape of the cam 63, that is, the effect of lifting the upper pressing cylinder 2 is achieved, the corresponding slider 55 slides up synchronously and compresses the spring 52, and the upper pressing cylinder 2 is continuously lifted up by the gradual rotation of the worm wheel 62, but the outermost end of the cam 63 is not generally moved to a position contacting with the catch wheel 64 (that is, the state that the outermost end of the cam 63 is vertically downward). In addition, after the position of the upper pressing cylinder 2 is adjusted, since the first positioning column 65 contacts with the second positioning column 66 and the first positioning column 65 is located above the second positioning column 66, the worm wheel 62 and the worm 61 are meshed with each other, and meanwhile, the cam 63 keeps a downward movement trend by using the elasticity of the spring 52, so that the first positioning column 65 can effectively prevent the second positioning column 66 and the cam 63 from rotating upwards by using a self-locking structure formed by the mutual meshing of the worm wheel 62 and the worm 61 and the action of the spring and the like, that is, the upper pressing cylinder 2 cannot descend, and the distance between the upper pressing cylinder 2 and the lower pressing cylinder 3 is ensured. Therefore, this structure can effectively prevent the upper press cylinder 2 from naturally lowering in height due to various reasons after the machine is used for a long time, can prevent it from affecting the normal passage of the work, that is, can avoid crushing the work after the upper press cylinder 2 is lowered.

When the position of the upper pressing cylinder 2 needs to be adjusted downwards, the worm 61 can be reversely rotated, so that the worm 61 is utilized to drive the worm wheel 62 and the first positioning column 65 to rotate upwards, and then the first positioning column 65 is separated from the second positioning column 66, and after the worm wheel 62 rotates upwards, the sliding block 55 and the upper pressing cylinder 2 can move downwards only by correspondingly rotating the first rotating shaft 8 to enable the cam 63 to rotate upwards for a plurality of distances under the action of the stretching force of the spring 52.

In the case of machine adjustment or maintenance, the adjustment handle 67 is only required to be directly rotated, so that the cam 63 is rotated downwards to the position of the catch wheel 64, and the position of the upper pressing cylinder 2 can be continuously increased along with the continuous rotation of the adjustment handle 67 until the upper pressing cylinder 2 reaches the desired position, and of course, the highest position to which the upper pressing cylinder 2 can be lifted is the position where the outermost end point of the cam 63 is moved to be in contact with the catch wheel 64.
