Description

Technical Field

[0001] This application relates to the field of die molds, and particularly to a method for pasting indentation strips and explosion-proof strips. Background Art

[0002] Flat die molds are very commonly used tools in the packaging industry. Blades are provided on the flat die molds, and the packaging materials are cut or indented by the blades to meet the usage requirements.

[0003] The blade is flat-topped, round-topped or semi-circular arc-topped, or has a blade edge. When the blade is non-sharp at the top such as flat-topped, round-topped or semi-circular arc-topped, it is called an indentation knife, which is used to punch the packaging material to form a crease; when the blade has a blade edge, it is used to punch the packaging material. In this application, the indentation knife and the blade edge are collectively referred to as the knife line.

[0004] Corresponding to the flat die mold, an upper die also needs to be configured for use. An indentation strip body needs to be provided on the upper die corresponding to the indentation knife, and the indentation strip body plays a positioning role for the knife line bayonet on the flat die mold; explosion-proof strips need to be provided at some positions on the flat die mold to prevent the product from having burrs on the edge or rough surface during the punching process.

[0005] In this industry, the traditional method is to first cut the indentation strips and explosion-proof strips according to the length, and then manually install a pile of indentation strips and explosion-proof strips on the corresponding knife lines or paste them on both sides of the knife lines. The work efficiency is low, it takes a lot of time, and it is easy to delay normal production.

[0006] A method for pasting indentation strips and explosion-proof strips has become a demand. Summary of the Invention

[0007] In view of at least one of the above technical problems, this application provides a method for pasting indentation strips and explosion-proof strips.

[0008] An embodiment of the first aspect of this application provides a method for pasting indentation strips and explosion-proof strips, which includes the following steps:

[0009] S1. Prepare the indentation strip or explosion-proof strip;

[0010] S2. Generate the size parameters and the positions to be pasted of the indentation strip or explosion-proof strip according to the distribution map of the knife lines on the knife template;

[0011] S3. Cut the indentation strip or explosion-proof strip according to the size parameters;

[0012] S4. Paste the indentation strip or explosion-proof strip on the corresponding position to be pasted on the knife template, and the position to be pasted is on one side of the knife line;

[0013] S5. Repeat S1 to S4 until all indentation strips or explosion-proof strips are pasted onto the corresponding positions to be pasted on the knife template, and the positions to be pasted are on one side of the knife line.

[0014] As a further improvement of the present invention, S6. Manually install the indentation strip onto the knife line.

[0015] As a further improvement of the present invention, in S6, at this time, the adhesive side of the indentation strip is upward, and the oil paper on the adhesive is torn off.

[0016] As a further improvement of the present invention, fix the knife template below the upper die, and press the upper die onto the knife template, so that the indentation strip is fixed on the upper die, and then tear off the soft glue on the indentation strip to complete the operation.

[0017] As a further improvement of the present invention, when the knife line is an indentation knife, the one cut and installed on the indentation knife is an indentation strip;

[0018] When the knife line is a blade edge, the one cut and installed on one side of the blade edge is an explosion-proof strip.

[0019] As a further improvement of the present invention, in S4, the indentation strip or explosion-proof strip is pasted parallel to the corresponding knife line on one side of the knife line.

[0020] As a further improvement of the present invention, when the width on one side of the corresponding knife line is less than the length of the indentation strip or explosion-proof strip, the indentation strip or explosion-proof strip is obliquely pasted on one side of the knife line.

[0021] As a further improvement of the present invention, in S4, apply glue dots to the indentation strip or explosion-proof strip, and then paste the indentation strip or explosion-proof strip onto the knife template.

[0022] As a further improvement of the present invention, in S2, the dimensional parameters of the indentation strip or explosion-proof strip are the length of the indentation strip or explosion-proof strip and / or the cutting angles at both ends.

[0023] As a further improvement of the present invention, it further includes the following step, S7. Manually separate the explosion-proof strip and paste it on both sides of the knife line corresponding to the position to be pasted.

[0024] The embodiments of the present application have the following technical effects: The present invention is reasonably and ingeniously designed. Before cutting the indentation strip or explosion-proof strip, cutting parameters are generated corresponding to the knife line diagram, so that after cutting one indentation strip or explosion-proof strip, it is immediately pasted on one side of the corresponding knife line, playing a role of quick matching and positioning. During the handling process, the indentation strip and explosion-proof strip still stay on one side of the corresponding knife line. When all the indentation strips or explosion-proof strips are cut, the indentation strip can be quickly removed and installed on the knife line, or the explosion-proof strip can be pasted on both sides of the knife line. Compared with the traditional process, it saves a large amount of time for comparing and finding the corresponding knife line, and effectively improves work efficiency.

[0039] As Figures 1 to 8 shown, the embodiments of the present application provide a method for pasting an indentation strip and an explosion-proof strip, which includes the following steps:

[0040] S1. Prepare the indentation strip 1 or the explosion-proof strip 2;

[0041] S2. Generate the size parameters and the positions to be pasted of the indentation strip 1 or the explosion-proof strip 2 according to the distribution diagram of the knife lines 4 on the knife template 3;

[0042] S3. Cut the indentation strip 1 or the explosion-proof strip 2 according to the size parameters;

[0043] S4. Paste the indentation strip 1 or the explosion-proof strip 2 onto the corresponding position to be pasted on the knife template 3, and the position to be pasted is on one side of the knife line 4;

[0044] S5. Repeat S1 to S4 until all the indentation strips 1 or the explosion-proof strips 2 are pasted onto the corresponding positions to be pasted on the knife template 3, and the position to be pasted is on one side of the knife line 4;

[0045] S6. Manually install the indentation strip 1 onto the knife line 4.

[0046] Figures 1 to 4 Although the indentation strip 1 is shown, the corresponding explosion-proof strip 2 also needs to go through the same processing steps.

[0047] As Figure 1 shown, Figure 1 inside is the indentation strip 1, which is straight.

[0048] As Figure 2 shown, after generating the dimensional parameters of the indentation strip 1 or the explosion-proof strip 2 according to the distribution diagram of the cutting lines 4 on the cutting template 3, the parameters corresponding to the indentation strip 1 or the explosion-proof strip 2 are generated according to the cutting lines 4 at different positions. Then, according to these parameters, the indentation strip 1 as Figure 1 shown is cut. The parameters of the indentation strip 1 or the explosion-proof strip 2 include length, cutting angles at both ends, etc.

[0049] In this embodiment, the dimensional parameters of the corresponding indentation strip 1 or explosion-proof strip 2 can be obtained through common drawing software according to the distribution diagram of the cutting lines 4, or through professional design software, or through a specially set program.

[0050] As Figures 3 to 5 shown, sponges 5 are pasted on both sides of the cutting line 4. During the die-cutting process, at some positions, due to concentrated pressure, the product may have edge bursting or surface roughness. The explosion-proof strip 2 needs to replace the sponges 5 at the corresponding positions to prevent the product being stamped from easily having edge bursting or surface roughness when the upper die and the cutting template are closed. The explosion-proof strip can disperse the pressure because it is made of a relatively hard elastic material.

[0051] In S6, at this time, the adhesive side of the indentation strip is facing up, and the oil paper on the adhesive is torn off.

[0052] Fix the cutting template 3 under the upper die, and the upper die is pressed onto the cutting template 3, so that the indentation strip 1 or the explosion-proof strip 2 is fixed on the upper die. Then, tear off the soft glue on the indentation strip 1 to complete the operation.

[0053] When the upper die is pressed onto the cutting template 3, the indentation strip 1 or the explosion-proof strip 2 is fixed to the upper die by adhesive. At this time, tear off the soft glue on the indentation strip 1, and the adhesive part remains on the upper die, that is, the operation is completed.

[0054] As Figure 6 shown, the indentation strip 1 includes a concave soft glue strip 11 and an adhesive-backed indentation strip main body 12 located below the soft glue strip 11. The adhesive is pasted with oil paper. During use, the soft glue strip 11 is stuck on the indentation knife, and the oil paper on the adhesive is torn off. After the upper die is pressed onto the cutting template 3, the indentation strip 1 is pasted onto the upper die, and then the soft glue strip 11 is torn off, and the indentation strip main body 12 remains on the upper die. The indentation strip main body 12 is provided with a groove corresponding to the indentation knife, and the indentation strip main body 12 plays a positioning role for the indentation knife.

[0055] When the knife line 4 is an indentation knife, the indentation strip 1 is cut and installed on the indentation knife;

[0056] When the knife line 4 is a cutting edge, the explosion-proof strip 2 is cut and installed on one side of the cutting edge.

[0057] In S4, the indentation strip 1 or the explosion-proof strip 2 is pasted parallel to the corresponding knife line 4 on one side of the knife line 4.

[0058] When the width on one side of the corresponding knife line 4 is less than the length of the indentation strip 1 or the explosion-proof strip 2, the indentation strip 1 or the explosion-proof strip 2 is obliquely pasted on one side of the knife line 4.

[0059] In S4, the indentation strip 1 or the explosion-proof strip 2 is dot-glued and then pasted onto the knife template 3.

[0060] Dot-gluing the indentation strip 1 or the explosion-proof strip 2 can be carried out by a specially set dot-gluing device or manually. When carried out by the dot-gluing device, the dot-gluing device can be set on the cutting machine or on the main body of the cotton-pasting machine. And dot-gluing can be carried out before or after cutting the indentation strip 1 or the explosion-proof strip 2.

[0061] In S2, the dimensional parameters of the indentation strip 1 or the explosion-proof strip 2 are the length of the indentation strip 1 or the explosion-proof strip 2 and / or the cutting angles at both ends.

[0062] As Figure 3 or Figure 5 shown, after cutting an indentation strip 1 or an explosion-proof strip 2, it is pasted on one side of the corresponding knife line 4.

[0063] Repeat S1 to S4. When all the indentation strips 1 or explosion-proof strips 2 are pasted onto the corresponding positions to be pasted on the knife template 3, and this position to be pasted is on one side of the knife line 4, as Figure 4 shown. Among them, some indentation strips 1 or explosion-proof strips 2 with too long dimensions can be obliquely pasted on one side of the corresponding knife line 4.

[0064] In S4 and S5, the indentation strip 1 and the explosion-proof strip 2 are only partially pasted on the knife template 3, playing a role of temporary fixation to prevent the position of the indentation strip 1 or the explosion-proof strip 2 from moving during the handling of the knife template 3, so that the indentation strip 1 or the explosion-proof strip 2 is not on the side of the original corresponding knife line, increasing the manpower and time required for subsequent processes.

[0065] As Figure 7 、 Figure 8As shown, in S7, manually separate the explosion-proof strip and paste it on both sides of the cutting line corresponding to the position to be pasted. It is necessary to remove the fixed explosion-proof strip in S4 and S5 from the knife template, divide the explosion-proof strip into two, and then paste it on both sides of the corresponding cutting line, sandwiching the cutting line in the middle of the explosion-proof strip, thus completing the entire installation process.

[0066] In other embodiments, the explosion-proof strip can also be separated and pasted on both sides of the guide corresponding to the position to be pasted by a machine.

[0067] When the indentation strip is pasted on the corresponding position to be pasted on the knife template, the indentation strip is partially pasted on the knife template for temporary fixation to prevent the indentation strip from being moved to the side of other cutting lines and affecting subsequent operations. In S6, it is necessary to first tear off the indentation strip from the knife template. Since the indentation strip is only partially pasted on the knife template, it can be easily torn off from the knife template, and then the indentation strip is installed on the cutting line.

[0068] The design of the present invention is reasonable and ingenious. Before cutting the indentation strip 1 or the explosion-proof strip 2, cutting parameters are generated corresponding to the cutting line 4 in the figure, so that after cutting one indentation strip 1 or explosion-proof strip 2, it is immediately pasted on one side of the corresponding cutting line 4. When all the indentation strips 1 or explosion-proof strips 2 are cut, they can be quickly installed on the cutting line 4. Compared with the traditional process, a large amount of time for comparing and finding the corresponding cutting line 4 is saved, effectively improving the work efficiency.

[0069] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, all equivalent changes made according to the shape, structure and principle of the present application without departing from the content of the technical solution of the present application shall be covered by the protection scope of the present application.
