TECHNICAL FIELD

[0002] The transfer film is a special printing material, which takes a polymer film as a base material, coats different colors, patterns or characters of the transfer printing ink on the film surface through special printing process and technology, and then transfers the printed patterns or characters to the surfaces of various materials such as plastics, paper, metals and glasses through a heat transfer printing machine or other equipment, so as to realize permanent bonding of the patterns or characters.

[0003] In the production process of the transfer film, the transfer film needs to be slitted into different widths according to the needs of customers, and when the customers need to paste the transfer film on a workpiece with a specific shape, the transfer film needs to be pre-cut into a specific shape during production, so as to facilitate the use of the customers.

[0038] As a technical optimization scheme of the present application, a sliding shaft 29 is arranged below the first spool 5, a sliding sleeve 31 is slidably arranged outside the sliding shaft 29, one end of the sliding sleeve 31 is provided with a connecting disc 30, one end of the connecting disc 30 can contact with the sliding sleeve 31, and the other end is fixedly connected with a second push rod 37, one end of the second push rod 37 away from the connecting disc 30 is fixedly connected with the side plate 1, and an intermediate shaft 33 is also arranged below the first spool 5, and two sets of limiting discs 34 are arranged on the intermediate shaft 33, each set of limiting discs 34 includes two limiting discs 34, the limiting discs 34 are connected with the intermediate shaft 33, and the distance between the two sets of limiting discs 34 is greater than the width of the heat transfer film 3 on the first spool 5, and when the engraving blade 16 continuously cuts, continuous heat transfer film 3 waste is generated, at this time one end of the heat transfer film 3 waste is wound outside the sliding sleeve 31, an external motor drives the limiting discs 34 to rotate, the limiting discs 34 drive the sliding shaft 29 and the sliding sleeve 31 to rotate, so that the continuous heat transfer film 3 waste is wound on the sliding sleeve 31, at this time the second push rod 37 moves back and forth to drive the connecting disc 30 and the sliding sleeve 31 to move back and forth along the length direction of the sliding sleeve 31, so that the heat transfer film 3 waste is wound at different positions on the sliding sleeve 31, and the sliding sleeve 31 can wind more heat transfer film 3 waste.

[0039] As a technical optimization scheme of the present application, the inner sleeve 31 is provided with an inner spline 39, the outer side of the sliding shaft 29 is provided with an outer spline 38, the end of the sliding shaft 29 away from the second push rod 37 is provided with a rotating disc 32, the rotating disc 32 is rotatably connected with the side plate 1, the rotating disc 32 is also provided with an inner spline 39, the end of the connecting disc 30 close to the inner sleeve 31 is embedded with a magnetic block 40, the magnetic block 40 can attract the inner sleeve 31, the end of the sliding shaft 29 away from the rotating disc 32 is provided with a stop block 36, one end of the stop block 36 is rotatably connected with the side plate 1 through a limiting shaft 35. After a certain amount of waste is wound on the inner sleeve 31, the stop block 36 is rotated, so that the stop block 36 no longer blocks the sliding shaft 29, and the sliding shaft 29 is pulled out from one side of the side plate 1. Since the sliding shaft 29 and the inner sleeve 31 are connected through the outer spline 38 and the inner spline 39, the inner sleeve 31 can be removed, and then the waste on the inner sleeve 31 can be treated, so that the continuous waste of the heat transfer film 3 is avoided, thereby affecting the cutting of the heat transfer film 3.

[0040] In use, first, according to the needs of customers, the position of the mounting sleeve 4 and the cutting blade is adjusted, when the cutting heat transfer film 3 passes through the feeding shaft 2, the cutting blade on the mounting sleeve 4 cuts the heat transfer film 3, and the first reel 5 and the second reel 6 are used to wind the cut heat transfer film 3, thereby completing the cutting process, the feeding shaft 2, the first reel 5 and the second reel 6 are all driven by an external motor.

[0041] The long rod 8, the short rod 9 and the cross plate 12 are driven by electric sliding blocks, and the rotating shaft 14 is driven by an external motor; when the heat transfer printing film 3 needs to be cut into a predetermined shape, the heat transfer printing film 3 after slitting passes above the cross plate 12, the rotating shaft 14 drives the spiral block 15 to rotate, the upper part of the spiral block 15 contacts the heat transfer printing film 3, and when the spiral block 15 rotates, the heat transfer printing film 3 in contact with the spiral block 15 is pushed to both sides, so that the heat transfer printing film 3 is opened to both sides, then the long rod 8 and the short rod 9 drive the engraved blade 16 to move, and the heat transfer printing film 3 is cut, so that the heat transfer printing film 3 is cut into a predetermined shape, which is convenient for the customer to paste the heat transfer printing film 3 on the workpiece of a predetermined shape, and the heat transfer printing film 3 forms a certain tension in the longitudinal direction during winding, and a certain tension is formed in the transverse direction by the spiral block 15, so that the heat transfer printing film 3 is relatively uniform and flat, the engraved blade 16 cuts more accurately, and the heat transfer printing film 3 is cut under the condition that the heat transfer printing film 3 is only stretched in the longitudinal direction, which leads to inaccurate cutting position of the heat transfer printing film 3, thereby reducing the quality of the heat transfer printing film 3; when the spiral block 15 rotates, the surface in contact with the heat transfer printing film 3 applies an oblique force to the heat transfer printing film 3, the oblique force can be decomposed into transverse and longitudinal directions, the transverse force pulls the heat transfer printing film 3 to both sides, because the heat transfer printing film 3 moves in the longitudinal direction, the spiral block 15 does not pull the heat transfer printing film 3 in the longitudinal direction, and the heat transfer printing film 3 is pushed by the spiral block 15 to avoid excessive tension of the heat transfer printing film 3 in the longitudinal direction, which leads to uneven winding, and excessive tension of the heat transfer printing film 3 in the longitudinal direction also affects the cutting effect of the engraved blade 16.

[0042] After the heat transfer printing film 3 produced is cut by the cutting blade on the mounting sleeve 4, the heat transfer printing film 3 of a certain width required by the customer is wound by the first winding shaft 5, and the remaining raw material is wound by the second winding shaft 6, when the heat transfer printing film 3 required by the customer needs to be cut into a predetermined shape, the heat transfer printing film 3 is cut by the long rod 8, the short rod 9, the engraved blade 16 and the spiral block 15, so that the heat transfer printing film 3 meets the needs of the customer; at the beginning of cutting, the heat transfer printing film 3 needs to be manually pulled by the staff and wound on the first winding shaft 5 or the second winding shaft 6, and then the first winding shaft 5 and the second winding shaft 6 can be used for automatic winding.

[0043] The bolt 18 is loosened, 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, so that the two spiral blocks 15 can adapt to heat transfer printing films 3 of different widths, and by replacing spiral blocks 15 of different pitches, the heat transfer printing film 3 of different winding speeds can be adapted.

[0044] The cutting scrap of the thermal transfer film 3 cut by the engraving blade 16 falls on the horizontal plate 12, at this time, the first push rod 22 is extended to push the cleaning plate 21 to move, the cleaning plate 21 moves to the horizontal plate 12, the rollers 27 are in contact with the horizontal plate 12, the cutting knives 28 are located between the gaps of the rollers 27, the thermal transfer film 3 on the horizontal plate 12 is further cut into pieces under the extrusion of the rollers 27, at this time, the rollers 27 roll along the top of the horizontal plate 12, when the first push rod 22 is retracted, the first push rod 22 pulls the cleaning plate, the rollers 27 are installed on the mounting shaft 26 through the one-way rotating bearing, at this time, the rollers 27 cannot rotate, the bottom of the rollers 27 pushes the cutting scrap of the thermal transfer film 3, so that the cutting scrap of the thermal transfer film 3 falls into the collecting box 19, the staff does not need to collect the cutting scrap, and the cutting scrap of the thermal transfer film 3 is more convenient to handle after being further cut.

[0045] When the engraving blade 16 continuously cuts, the continuous waste of the thermal transfer film 3 is generated, at this time, one end of the waste of the thermal transfer film 3 is wound outside the sliding sleeve 31, the motor outside the sliding sleeve 31 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 of the thermal transfer film 3 is wound on the sliding sleeve 31, at this time, the second push rod 37 continuously extends and retracts to drive the connecting disc 30 and the sliding sleeve 31 to move back and forth along the length direction of the sliding sleeve 31, so that the waste of the thermal transfer film 3 is wound at different positions of the sliding sleeve 31, and more waste of the thermal transfer film 3 can be wound on the sliding sleeve 31;

[0046] When the sliding sleeve 31 winds a certain amount of waste, the stop block 36 is rotated to make the stop block 36 no longer block the sliding shaft 29, the sliding shaft 29 is pulled out from one side of the side plate 1, since the sliding shaft 29 and the sliding sleeve 31 are connected through the external spline 38 and the internal spline 39, the sliding sleeve 31 can be taken off, then the waste on the sliding sleeve 31 can be handled, and the continuous waste of the thermal transfer film 3 is avoided from accumulating, so as to affect the cutting of the thermal transfer film 3.

[0047] When the sliding sleeve 31 winds the continuous waste of the thermal transfer film 3, the waste of the thermal transfer film 3 passes through the limiting disc 34, the distance between the two groups of limiting discs 34 is slightly greater than the width of the thermal transfer film 3 to be cut, so that the waste of the thermal transfer film 3 is slightly pulled outward, the waste of the thermal transfer film 3 is avoided from winding the engraving blade 16, and the cutting effect is affected.

[0048] The first spool 5 winds the thermal transfer film 3 with a predetermined width required by the customer, the second spool 6 winds the remaining raw material, the sliding sleeve 31 and the intermediate shaft 33 wind the continuous waste cut down, and the discontinuous waste cut down falls on the horizontal plate 12.

[0049] The end of the connecting disc 30 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 the connecting disc 30 moves. The first push rod 22 and the second push rod 37 are both electric push rods.

[0050] The above merely provides the preferred but not limiting embodiments of the present application, and the protection scope of the present application should not be limited thereto. Any skilled person in the art, according to the technical solution and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
