[0002] Existing die-cut adhesive backing waste absorption structures are generally integrated into waste absorption etching molds or engraving etching molds, which are blade plates + aluminum plates or blade plates + steel plates (see...). Figure 1 It is composed of components, with a horizontally penetrating waste suction groove made at the location of the waste suction hole in the steel or aluminum plate, such as... Figure 2 As shown, the waste is cleaned periodically by hand or by air according to the size of the waste and the number of times the die is punched. If the cleaning is not timely, there is even a risk of die breakage. Especially when the waste is large, it not only seriously affects the production efficiency, but also poses a certain danger if the manual cleaning of waste is not handled properly. Therefore, the existing structure is difficult to meet the needs of the rapidly developing die-cutting industry, and a more efficient, convenient and safer mold structure is needed.

[0007] And a waste suction tank carrier, which is provided with a waste suction tank corresponding to the position of each group of guide through holes. The waste suction tank includes a bottom inlet hole, an inner curved guide surface, a bottom surface, and two side surfaces. The inner curved guide surface is arranged in an outward arc from bottom to top. The outer end of the waste suction tank is connected to the outside atmosphere. The bottom of the inner curved guide surface is connected to the inner end of the bottom surface. The upper part of the bottom inlet hole corresponds to the lower part of the inner curved guide surface.

[0008] The bottom etching waste suction blade is fixed to the die support plate, the upper part of the die support plate is fixed to the waste suction groove carrier, the closed surface area blade cavity structure is connected to the guide through hole, and the guide through hole is connected to the bottom feed hole.

[0009] Its further features are:

[0010] The surface area of ​​the bottom feed hole covers the bottom surface of the corresponding waste suction tank, and the waste enters the waste suction tank after passing through the guide through hole;

[0011] The guide through holes are aligned and arranged directly above the cavity structure of the closed surface area blade, ensuring that the cut waste material can reliably and smoothly enter the waste suction tank under the external adsorption of the waste suction tank.

[0022] Bottom etching waste suction knife 10, cavity structure 11, die support plate 20, guide through hole 21, waste suction groove carrier 30, waste suction groove 40, inner curved guide surface 41, side surface 42. Detailed Implementation

[0023] An automatic waste suction and cleaning-free waste material mold structure, see Figure 1 and Figure 2 It includes a bottom etching waste suction knife 10, a die support plate 20, and a waste suction tank carrier 30;

[0024] The bottom etching waste suction knife 10 has a downwardly convex closed surface blade corresponding to the punching position on both sides of the material width direction. The center of the closed surface blade is a cavity structure 11.

[0025] The die-cutting support plate 20 is provided with a guide through hole 21 corresponding to the position of the cutting edge of the closed surface region;

[0026] Waste suction tank carrier 30 is provided with waste suction tank 40 corresponding to the position of each group of guide through holes 21. Waste suction tank 40 includes bottom inlet hole, inner curved guide surface 41, bottom surface, and two side surfaces 42. The inner curved guide surface 41 is arranged in an outward arc from bottom to top. The outer end of waste suction tank 40 is connected to the outside atmosphere. The bottom of the inner curved guide surface 41 is connected to the inner end of the bottom surface. The upper part of the bottom inlet hole corresponds to the lower part of the inner curved guide surface 41.

[0027] The bottom etching waste suction knife 10 is fixed to the die support plate 20, and the upper part of the die support plate 20 is fixed to the waste suction groove carrier 30. The cavity structure 11 of the closed surface area blade is connected to the guide through hole 21, and the guide through hole 21 is connected to the bottom feed hole.

[0028] In a specific embodiment, the surface area of ​​the bottom feed hole covers the bottom surface of the corresponding waste suction tank 40, and the waste enters the waste suction tank 40 after passing through the guide through hole 21.

[0029] The guide through hole 21 is aligned and arranged directly above the cavity structure 11 of the closed surface area blade, ensuring that the cut waste material is reliably and smoothly admitted into the waste suction tank 40 under the external adsorption effect.

[0030] In a preferred embodiment, the inner curved guide surface 41 is an arc-shaped guide surface, which makes the processing convenient and reliable;

[0031] The inner curved guide surface 41 is coated with Teflon, so that after the waste is stacked, it will eventually fall automatically through the outer end of the waste suction groove 40 along the inner curved guide surface.

[0032] The die-cutting support plate 20 is made of steel, which ensures reliable support for the entire structure;

[0033] The waste suction tank carrier 30 is made of aluminum or aluminum alloy, which makes the structure relatively lightweight but easy to process.

[0034] In practice, three sets of downward-convex closed-area blades are arranged at equal intervals on both sides of the width direction of the bottom etched waste suction blade 10, which is suitable for products where the waste is located on both sides of the width direction; the closed-area blades are annular blades, and the guide through hole 21 is a micro-flare hole with a corresponding diameter that expands from bottom to top to ensure that the waste is reliably adsorbed and discharged.

[0035] Its working principle is as follows: The entire structure is equipped with a die-cutting support plate. Since the waste suction tank is set on the side corresponding to the width, instead of a straight groove that runs horizontally through, the weight of the waste suction tank carrier will increase relatively. Therefore, by setting the die-cutting support plate, the stability and reliability of the entire structure can be ensured. The waste material enters the corresponding waste suction tank under vacuum adsorption state along the cavity structure of the closed surface blade and the guide through hole. The waste material is adsorbed onto the inner curved guide surface, and its direction is automatically adjusted by the inner curved guide surface of the waste suction tank. The suction mechanism is set at the outer end of the suction tank, and the waste material will be automatically discharged along the inner curved guide surface. This avoids the waste cleaning action of frequent machine shutdowns, which can greatly improve the convenience of production, production efficiency and the safety of production personnel.
