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 bolt 18 is unscrewed, the mounting block 17 and the vertical plate 13 can be moved along the vertical groove, so that the distance between the two spiral blocks 15 is adjusted, the two spiral blocks 15 can adapt to the heat transfer films 3 with different widths, and the spiral blocks 15 with different pitches can adapt to different winding speeds of the heat transfer films 3 by changing the spiral blocks 15.
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.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
