It uses die-cutting tools to combine into a die-cutting plate according to the pattern required by the product design, and cuts the material to be cut into the required shape under the action of pressure. In the existing die-cutting and forming process, the hot melt adhesive film is usually laminated with the original paper, and then the whole paving is cut in half to the original paper, and then the product shape is cut to obtain the product. This processing method is prone to problems such as poor hot melt adhesive film falling off, poor delamination, and poor cutting, which makes the defective rate of the process too high and causes waste of original paper.

[0040] Reference Figure 1 and Figure 2 The first embodiment of the present application provides an asynchronous die-cutting system, including a first unwinding roller 101, a second unwinding roller 102, a third unwinding roller 103, a first die-cutting device 105, a fourth unwinding roller 106, and a second die-cutting device 109, wherein the first unwinding roller 101 is used to release the bottom film; the second unwinding roller 102 is used to release the asynchronous film; the third unwinding roller 103 is used to release the hot-melt adhesive film; the first die-cutting device 105 is arranged on the moving path of the bottom film, the asynchronous film and the hot-melt adhesive film, and the first die-cutting device 105 is used to bond the bottom film, the hot-melt adhesive film and the asynchronous film to form a first composite, and perform Die-cutting; wherein, the asynchronous film is located between the hot-melt adhesive film and the bottom film; the fourth unwinding roller 106 is used to release the original paper; the second die-cutting device 109 is arranged on the moving path of the first composite body and the original paper, and the second die-cutting device 109 is used to die-cut the second composite body; when the asynchronous die-cutting system of the embodiment of the present application is working, the hot-melt adhesive film, the bottom film and the asynchronous film are bonded together to form a first composite body through the first die-cutting device 105, and the first composite body is die-cut, and the asynchronous film is located between the hot-melt adhesive film and the bottom film; then the second composite body formed by bonding the first composite body and the original paper is die-cut by the second die-cutting device 109. In the related art, generally the whole material is laid out for die cutting, the hot melt adhesive film is attached to the upper surface of the original paper and then the hot melt adhesive film is die-cut, and then the product shape is obtained by cutting. Since the original paper is not hard enough, die-cutting the hot melt adhesive film on the original paper is prone to cause problems such as poor hot melt adhesive film falling off, poor delamination, and poor cutting. The asynchronous die-cutting system of the embodiment of the present application first attaches the hot melt adhesive film to the asynchronous film to form a first composite body, die-cuts the first composite body, and die-cuts the hot melt adhesive film on the asynchronous film, attaches the die-cut first composite body to the original paper to form a second composite body, and then die-cuts the second composite body. Since the hardness of the asynchronous film is higher than that of the original paper, for example, the asynchronous film can be a PET release film, so the problems of poor hot melt adhesive film falling off, poor delamination, and poor cutting can be reduced, the yield rate can be improved, and the production cost can be reduced.

[0041] It can be understood that the bottom film and the asynchronous film can be release films, such as PET release films and the like.

[0042] It can be understood that the asynchronous die-cutting system also includes a first laminating device 104, which is arranged on the moving path of the asynchronous film and the hot-melt adhesive film. The first laminating device 104 is used to laminate the asynchronous film and the hot-melt adhesive film so that the hot-melt adhesive film is located on the upper surface of the asynchronous film during laminating, so that the first die-cutting device 105 can laminate the bottom film, the hot-melt adhesive film and the asynchronous film to form a first composite body, and die-cut the first composite body.

[0043] It is understandable that the asynchronous die-cutting system further includes a heating device 107, which is arranged between the second die-cutting device 109 and the first die-cutting device 105. The heating device 107 includes a support frame 1071, on which a heating plate 1073 is laid, and on which a plurality of pressing rollers 1072 are arranged, and the pressing rollers 1072 are used to bond the original paper to the first composite body to form a second composite body. The heating plate 1073 can heat the first composite body and the original paper, and the hot melt adhesive film in the first composite body can generate viscosity after being heated, so that it can be bonded to the original paper, and cooperate with the pressing rollers 1072 to bond the original paper to the first composite body to form a second composite body. The pressing rollers 1072 can be provided with two as shown in the figure, or can be provided with one, three or other numbers, and this application does not limit this. The heating temperature of the heating plate 1073 is 40°C to 60°C, and within this heating temperature range, the hot melt adhesive film can generate viscosity. For example, the heating temperature of the heating plate 1073 can be set to 45°C, and the hot melt adhesive film can be heated for 2 minutes to make the hot melt adhesive film sticky. It should be noted that those skilled in the art can set the heating temperature and heating time according to actual conditions, as long as the hot melt adhesive film can be made sticky, and this application does not limit this. In addition, the bonding of the original paper and the first composite body to form the second composite body can be completed by the heating device 107, or by the second die-cutting device 109.

[0044] It is understandable that the asynchronous die-cutting system further includes a cooling device 108, which is disposed between the heating device 107 and the second die-cutting device 109, and the cooling device 108 can cool the second composite body. For example, the cooling device 108 can cool the second composite body to 0°C, 5°C or 10°C, so that the hot melt adhesive film solidifies, and the hot melt adhesive film and the original paper are firmly attached, so that the second die-cutting device 109 can die-cut the second composite body. It should be noted that those skilled in the art can set the cooling temperature and heating time according to actual conditions, as long as the hot melt adhesive film can be solidified, and this application does not limit this.

The fifth unwinding roller 112 and the first winding roller 113 are both arranged between the first die-cutting device 105 and the heating device 107. The fifth unwinding roller 112 is used to release the waste tape and make the waste tape adhere to the hot-melt adhesive film waste. The first winding roller 113 is used to wind up the waste adhesive adhered with the hot-melt adhesive film waste, which can prevent the hot-melt adhesive film waste from affecting the subsequent operation of the asynchronous die-cutting system.

[0046] It is understandable that the asynchronous die-cutting system further includes a sixth unwinding roller 114, a second laminating device 115, and a second winding roller 116. The sixth unwinding roller 114, the second laminating device 115, and the second winding roller 116 are sequentially arranged between the first unwinding roller 101 and the second unwinding roller 102. The sixth unwinding roller 114 is used to release the dustproof paper, the second laminating device 115 is used to laminarize the dustproof paper with the bottom film, and the second winding roller 116 is used to roll up the dustproof paper. Since the bottom film is sticky, it is easy for the bottom film to stick to dust or other dirt when passing through the roller of the equipment. The dustproof paper is laminarized on the upper surface of the bottom film by the second laminating device 115, and then the bottom film is passed through the roller of the equipment, which can prevent the bottom film from sticking to dirt. The second winding roller 116 is used to roll up the dustproof paper, so that the dustproof paper can be reused to save resources.

[0047] It is understandable that, referring to Figure 1 The asynchronous die-cutting system further includes a manual table 111 and a transfer device 110.

The transfer device 110 is used to transfer the second composite body after die-cutting to obtain a product and deliver the product to the manual table 111. The manual table 111 is disposed on one side of the transfer device 110. The manual table 111 is used to receive the product delivered by the transfer device 110.

[0054] It is understandable that the heating device 107 is used to bond the original paper to the first composite body to form a second composite body, and the second composite body is heated so that the hot melt adhesive film in the first composite body can become sticky after being heated, so that the hot melt adhesive film can be bonded to the original paper.

[0055] It is understandable that laminating the original paper with the first composite body after die-cutting to form the second composite body includes: heating the hot melt adhesive film, and laminating the original paper on the hot melt adhesive film of the first composite body to form the second composite body. The second composite body is heated by the heating device 107, and the heating temperature of the heating treatment is 40°C to 60°C. Within this heating temperature range, the hot melt adhesive film can be made sticky; the heating time can be 2 minutes, for example, the heating temperature of the heating plate 1073 can be set to 45°C, and the hot melt adhesive film is heated for 2 minutes to make the hot melt adhesive film sticky. And the original paper is laminated to the hot melt adhesive film of the first composite body by the pressure roller 1072 of the heating device 107 to form the second composite body. It should be noted that those skilled in the art can set the heating temperature and heating time according to actual conditions, as long as the hot melt adhesive film can be made sticky, and this application does not limit this.

[0056] It is understandable that laminating the original paper with the die-cut first composite to form the second composite further includes: cooling the second composite. The second composite is cooled by the cooling device 108, and the second composite is cooled to 0°C, 5°C or 10°C by the cooling device 108, so that the hot melt adhesive film solidifies and the hot melt adhesive film and the original paper are firmly bonded. It should be noted that those skilled in the art can set the cooling temperature and heating time according to actual conditions, as long as the hot melt adhesive film can be solidified, and this application does not limit this.
