When the automatic cutting machine is used, firstly, the positions of the mounting sleeve 4 and the cutting blades are adjusted according to the needs of customers, when the thermal transfer film 3 to be cut passes through the feeding shaft 2, the cutting blades on the mounting sleeve 4 cut the thermal transfer film 3, the first scroll 5 and the second scroll 6 are used for rolling the cut thermal transfer film 3, so that the cutting process is finished, and the feeding shaft 2, the first scroll 5 and the second scroll 6 are driven by external motors.
The long rod 8, the short rod 9 and the transverse plate 12 are driven by an electric slide block, and the rotating shaft 14 is driven by an external motor; when the thermal transfer film 3 is required to be cut into a preset shape, the cut thermal transfer film 3 passes through the upper part of the transverse plate 12, the rotating shaft 14 drives the spiral block 15 to rotate, the upper part of the spiral block 15 is in contact with the thermal transfer film 3, the thermal transfer film 3 in contact with the spiral block 15 is pushed to two sides when the spiral block 15 rotates, so that the thermal transfer film 3 is opened to two sides, then the long rod 8 and the short rod 9 drive the engraving blade 16 to move, the thermal transfer film 3 is cut into the preset shape, a client is facilitated to attach the thermal transfer film 3 to a workpiece in the preset shape, a certain tensile force is formed in the longitudinal direction of the thermal transfer film 3 in the winding process, a certain tensile force is formed in the transverse direction by the spiral block 15, and therefore the thermal transfer film 3 is relatively uniform and flat, the engraving blade 16 is more accurate when being cut, the thermal transfer film 3 is prevented from being cut only under the condition of being stretched in the longitudinal direction, so that the incision position of the thermal transfer film 3 is inaccurate, and the quality of the thermal transfer film 3 is reduced; when the spiral block 15 rotates, an oblique force is applied to the thermal transfer film 3 on the surface contacted with the thermal transfer film 3, the oblique force can be decomposed into transverse force and longitudinal force, the thermal transfer film 3 is pulled to two sides by the transverse force, the thermal transfer film 3 is longitudinally moved, the spiral block 15 cannot longitudinally pull the thermal transfer film 3, the thermal transfer film 3 is pushed by the spiral block 15, the situation that the thermal transfer film 3 is too large in tensile force in the longitudinal direction, uneven winding is caused, and the cutting effect of the engraving blade 16 is also affected by too large tensile force in the longitudinal direction of the thermal transfer film 3 is avoided.
After the produced thermal transfer film 3 is cut by a cutting blade on the mounting sleeve 4, the thermal transfer film 3 with a certain width required by a customer is wound by a first winding shaft 5, the rest raw materials are wound by a second winding shaft 6, and when the thermal transfer film 3 required by the customer is required to be cut into a preset shape, the thermal transfer film 3 is cut by a long rod 8, a short rod 9, an engraving blade 16, a spiral block 15 and the like, so that the thermal transfer film 3 meets the requirements of the customer; at the time of cutting at the beginning, the thermal transfer film 3 needs to be manually pulled by a worker and correspondingly wound on the first reel 5 or the second reel 6, and then the first reel 5 and the second reel 6 can be utilized for automatic winding.

The crushed aggregates of the thermal transfer films 3 cut by the engraving blade 16 fall on the transverse plate 12, at the moment, the first push rod 22 stretches to push the cleaning plate 21 to move, the cleaning plate 21 moves to the transverse plate 12, the roller 27 is in contact with the transverse plate 12, the cutting knife 28 is positioned in a gap between the rollers 27, the thermal transfer films 3 on the transverse plate 12 are further cut into fragments under the extrusion of the roller 27, at the moment, the roller 27 rolls along the top of the transverse plate 12, when the first push rod 22 contracts, the cleaning plate is pulled by the first push rod 22, the roller 27 is mounted on the mounting shaft 26 through a unidirectional rotating bearing, at the moment, the roller 27 cannot rotate, the bottom of the roller 27 pushes the cut fragments of the thermal transfer films 3, so that the fragments of the thermal transfer films 3 fall into the collecting box 19, the fragments do not need to be collected by workers, and the further cut fragments of the thermal transfer films 3 are more convenient to process.
When the engraving blade 16 continuously cuts, continuous waste materials of the thermal transfer film 3 are generated, at the moment, one end of the waste materials of the thermal transfer film 3 are wound on the outer side of the sliding sleeve 31, an external motor drives the limiting disc 34 to rotate, the limiting disc 34 drives the sliding shaft 29 and the sliding sleeve 31 to rotate, so that the continuous waste materials of the thermal transfer film 3 are wound on the sliding sleeve 31, at the moment, the second push rod 37 continuously stretches and stretches to drive the connecting disc 30 and the sliding sleeve 31 to reciprocate along the length direction of the sliding sleeve 31, so that the waste materials of the thermal transfer film 3 are wound on different positions of the sliding sleeve 31, and the sliding sleeve 31 is convenient for winding more waste materials of the thermal transfer film 3;
after a certain amount of waste is rolled up on the sliding sleeve 31, the stop block 36 is rotated, so that the stop block 36 does not block the sliding shaft 29 any more, the sliding shaft 29 is pulled out from one side of the side plate 1, and the sliding shaft 29 and the sliding sleeve 31 are connected through the external spline 38 and the internal spline 39, so that the sliding sleeve 31 can be taken down, then the waste on the sliding sleeve 31 is treated, and the continuous accumulation of the waste of the thermal transfer film 3 is avoided, thereby influencing the cutting of the thermal transfer film 3.
When the continuous waste material of the thermal transfer film 3 is rolled by the sliding sleeve 31, the waste material of the thermal transfer film 3 passes through the limiting plates 34, and the distance between the two groups of limiting plates 34 is slightly larger than the width of the thermal transfer film 3 to be cut, so that the waste material of the thermal transfer film 3 is slightly pulled outwards, the waste material of the thermal transfer film 3 is prevented from winding the engraving blade 16, and the cutting effect is affected.
The heat transfer film 3 of a predetermined width required by a customer is wound up by the first reel 5, the second reel 6 winds up the cut surplus raw material, and the slide bush 31 and the intermediate shaft 33 wind up the cut continuous waste material, and the cut discontinuous waste material falls on the traverse plate 12.
The end of the connecting disc 30, which is close to the sliding sleeve 31, is embedded with a magnetic block 40 which can attract the sliding sleeve 31, so that the connecting disc 30 can drive the sliding sleeve 31 to move when moving. The first push rod 22 and the second push rod 37 are both electric push rods.
