Description

[Technical field]

[0001] The invention relates to the technical field of transfer films, in particular to the technical field of a transfer film slitting device. [Background technology]

[0002] Aluminum gussets are made of aluminum alloy sheets as the base, and are obtained by cutting, cutting corners and molding. There are two main types, one is home decoration integrated aluminum gussets, and the other is engineering aluminum gussets. With the development, home decoration integrated aluminum gussets have become diverse, and various processing technologies have been applied to them. Series such as thermal transfer, glaze, ink printing, mirror and 3D are the most popular home decoration integrated aluminum gussets in recent years. Thermal transfer is a process of transferring the decorative pattern on the thermal transfer to the surface of the decorated building material by heating the thermal transfer film once to form a high-quality finishing film. The thermal transfer film is made of polyethylene film as the backing paper, with a decorative layer printed on it, and a protective layer, a base color layer, a release layer and a hot melt adhesive layer coated on the surface. When in use, by heating the high-temperature silicon roller, temperature and pressure are applied to the transfer foil, so that the transfer layer composed of the decorative layer, surface protection layer and base color layer is separated from the polyethylene and transferred to the aluminum gusset plate, thereby forming a decorative surface pattern, which makes the aluminum gusset plate have excellent properties such as wear resistance, heat resistance and light resistance, and the pattern is novel and beautiful, and the color tone is stable.

[0003] Before using the thermal transfer film, it needs to be cut into appropriate sizes according to the size of the aluminum gusset plate. During cutting, the transfer film roll is sleeved on the feed roller, and the free end of the transfer film is fixed on the receiving roller.

[0024] Working process of the present invention:

[0025] First, the first clamping manipulator and the second clamping manipulator clamp the transfer film on the left and right sides respectively. After the cutting head 7 cuts the transfer film between the two manipulators, the third cylinder 33 and the fourth cylinder 34 retract the telescopic rods respectively, so that the second clamping manipulator releases the cut transfer film sheet, so that the transfer film sheet falls into the receiving box 5 along the material guide block 6. Then, the conveying motor 363 drives the conveying screw 361 to rotate, so that the conveying nut 362 drives the first clamping manipulator holding the end of the transfer film to move to the right, and at the same time, the second clamping manipulator moves to the left. Then, the third cylinder 33 and the fourth cylinder 34 extend the telescopic rods respectively, so that the second clamping manipulator presses the transfer film. When the two clamping manipulators complete the position exchange, the cutting head 7 performs the next round of cutting work.

[0026] When the transfer film roll 8 needs to be replaced, the limit block 24 is unscrewed from the cross bar 23 , and then the old transfer film roll 8 is removed, and a new transfer film roll 8 is sleeved outside the cross bar 23 , and then the limit block 24 is screwed back onto the cross bar 23 .

[0027] During operation, the cutting head 7 uses the cutter head motor 722 to drive the cutter head screw 723 to rotate, so that the cutter head screw rod 721 drives the cutter head base plate 73 and the blade 74 to move up and down to complete the cutting action. When the blade 74 retracts along the cutting groove 751 after each cutting, the transferred film that is attached can be directly blocked outside the bottom surface of the compartment 75. If the transfer film is highly attached, the blowing assembly 78 can be turned on, and the blowing motor 784 can be used in conjunction with the gear 782 and the toothed belt 783 to make the two rotating shafts 781 and the wind wheel 785 fixed thereon rotate intermittently, so that the air flow is intermittently blown out along the gap between the cutting groove 751 and the blade 74, and the transfer film is sprayed off the blade 74.

[0028] The present invention drives four cylinders equipped with pressure plates to move horizontally through four groups of conveying drivers respectively, so that the pressure plates facing each other form two groups of left and right clamping manipulators, and the two groups of clamping manipulators are used to continuously exchange positions, thereby clamping and driving the end of the transfer film to continuously move to the right for cutting work, and the transfer film roll has a high utilization rate and almost no scraps; by adjusting the screw-in distance of the limit block on the cross bar, the force of the limit pad pressing the reel of the transfer film roll is changed, thereby adjusting the tightness of the transfer film film release; by setting a guide block with an inclined surface on the top surface, it is convenient for the cut transfer film to automatically fall into the receiving box; by the cutter head driver, the cutter head bottom plate is driven to move up and down between the cutter head top plate and the compartment box, thereby driving the blade to move up and down along the cutting groove through the compartment box, so that when the blade retracts along the cutting groove after each cutting, the transfer film is directly blocked outside the bottom surface of the compartment box and separated from the blade; by setting an air blowing component in the compartment box, using an intermittently rotating wind wheel, and thus intermittently blowing, the transfer film can be effectively sprayed open.
