Description

Technical Field

[0001] The present invention relates to the technical field of transfer films, in particular to the technical field of a cutting head for transfer films.

Background Art

[0002] Aluminum gusset plates are made of aluminum alloy plates as the base, and are obtained through cutting, corner shearing and die pressing. There are mainly two types. One is the household integrated aluminum gusset plate, and the other is the engineering aluminum gusset plate. With the development, the household integrated aluminum gusset plates have been diverse, and various different processing techniques have been applied to them. Series such as heat transfer printing, glazed surface, ink printing, mirror surface and 3D are the most popular household integrated aluminum gusset plates in recent years. Heat transfer printing is a process of transferring the decorative pattern on the heat transfer film to the surface of the decorated building material by heating the heat transfer film once to form a high-quality decorative film. The heat transfer film uses a polyethylene film as the backing paper, with a decorative layer printed on it, and a protective layer, a base color layer, a demoulding layer and a hot melt adhesive layer are 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, the surface protective layer and the base color layer is separated from the polyethylene and transferred onto the aluminum gusset plate, thereby forming a decorative surface pattern, making the aluminum gusset plate have excellent properties such as wear resistance, heat resistance and light resistance, with novel and beautiful patterns and stable hues.

[0003] Before the heat transfer film is used, it needs to be cut into a suitable size according to the size of the aluminum gusset plate. During the cutting process, the cut transfer film is easily adhered to the cutting knife due to static electricity and needs to be peeled off separately, which is rather troublesome.

Several bumps 752 are respectively arranged on the bottom surface of the partition box 75 and on the left and right sides of the cutting blade 74. The cutting tool driver 72 includes a cutting tool lead screw 721, a cutting tool motor 722 and a cutting tool nut 723. The cutting tool motor 722 is fixed on the right side of the cutting tool top plate 71. The cutting tool nut 723 is located inside the cutting tool motor 722. The cutting tool lead screw 721 is threadedly connected to the cutting tool nut 723. The bottom end of the cutting tool lead screw 721 is connected to the cutting tool bottom plate 73. A side plate 77 is arranged on the top surface of the right side of the cutting tool top plate 71. A track 771 is arranged on the right side of the side plate 77. The top end of the cutting tool lead screw 721 is fixed with a slider 772. The slider 772 is slidably fixed on the track 771. Corresponding cutting grooves 751 are respectively arranged on the top surface and the bottom surface of the partition box 75. The cutting blade 74 passes through the cutting groove 751 and penetrates the partition box 75. The gap of the cutting groove 751 is larger than the thickness of the cutting blade 74. An air blowing assembly 78 is arranged inside the partition box 75. The air blowing assembly 78 includes a rotating shaft 781, a gear 782, a toothed belt 783, an air blowing motor 784 and a wind wheel 785. Two rotating shafts 781 are respectively rotatably fixed on the left and right sides of the cutting groove 751 through bearings. The gears 782 are respectively fixed at the positions close to the front and rear ends of the rotating shaft 781. The toothed belt 783 is sleeved outside the gears 782 at the same end.

[0019] Working process of the present invention:

[0020] The cutter head motor 722 drives the cutter head lead nut 723 to rotate, so that the cutter head lead screw 721 drives the cutter head bottom plate 73 and the blade 74 to move up and down, completing the cutting action. At the same time, the lead screw 721 drives the slider 772 to slide up and down on the track 771, enhancing the stability of the movement of the blade 74. When the blade 74 retracts along the cutting groove 751 after each cut, several bumps 752 can be used to push open the transfer film, so as to block the adhered transfer film outside the bottom surface of the partition box 75. If the adhesion of the transfer film is strong, the blowing assembly 78 can be turned on. The blowing motor 784 cooperates with the gear 782 and the toothed belt 783 to make the two rotating shafts 781 and the wind wheels 785 fixed thereon rotate intermittently, so that the air flow blows out intermittently along the first through hole and the gap between the cutting groove 751 and the blade 74, spraying the transfer film off the blade 74.

[0021] In the present invention, the cutter head driver drives the cutter head bottom plate to move up and down between the cutter head top plate and the partition box, so as to drive the blade to move up and down through the partition box along the cutting groove, so that when the blade retracts along the cutting groove after each cut, the transfer film is directly blocked outside the bottom surface of the partition box and separated from the blade; by respectively arranging several bumps on the bottom surface of the partition box and on the left and right sides of the blade, the transfer film is assisted to be pushed away from the blade; by arranging gaskets on the bottom surfaces of the bumps, the transfer film is prevented from being scratched by the bumps, reducing the defective rate; by arranging side plates with tracks and fixing the sliders slidingly fixed on the tracks on the lead screw, the stability of the up and down movement of the blade is effectively enhanced; by arranging a blowing assembly in the partition box and using intermittently rotating wind wheels, so as to blow air intermittently, the transfer film can be effectively sprayed open.

[0022] The above embodiments are illustrative of the present invention, not restrictive of the present invention. Any solution obtained by simply transforming the present invention belongs to the protection scope of the present invention.
