Description

Technical field

[0002] The utility model relates to the technical field of die-cutting equipment, in particular to a die-cutting machine capable of maintaining tension. [Background Technology]

[0004] Die-cutting machines are primarily used for cutting, punching, embossing, and die-cutting. The die-cutting machine's working principle is to use a steel knife, a metal mold, and a steel wire, applying a certain amount of pressure through a stamping plate to cut printed products or cardboard into a certain shape. Pressing and cutting an entire printed product into a single graphic product is called die-cutting; using a steel wire to press a mark or leave a curved groove on the printed product is called indentation; using two yin and yang templates and heating the mold to a certain temperature to hot-stamp a three-dimensional pattern or font on the surface of the printed product is called hot stamping; using one substrate to laminate onto another is called lamination; and excluding all parts except the genuine product is called waste removal. The above can be collectively referred to as die-cutting technology. When the die-cutting machine presses and cuts a single graphic product, the material strip is made of thin aluminum, which has low toughness and elasticity. The tension is insufficient during transportation, causing the strip to deviate before cutting.

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

A tensioning mechanism 1 is provided on the discharge side of the loading mechanism 2 for tensioning the material strip. A side on which the material strip continues to be conveyed is provided with a pressing mechanism 3 for pressing and shaping the material strip. After pressing and shaping, the material strip continues to be conveyed to a trimming mechanism 5 for trimming and shaping the material strip. The tensioning mechanism tensions the material strip, imparting tension to the material strip, preventing it from shifting during pressing and trimming. The coiled material is made of aluminum. The design of the tensioning mechanism in the die-cutting machine ensures that the overall structural tension of the aluminum sheet remains stable during conveyance, maintaining consistent position during conveyance before cutting. The dimensions of the product after pressing and cutting meet production requirements. The tensioning mechanism ensures the stability and straightness of the material strip during processing, preventing product defects caused by loose or shifted material.

The first cylinder 116, which moves roller 115 toward the first tensioning roller 112, pushes the second tensioning roller 115 toward the first tensioning roller 112. The distance between the second and first tensioning rollers can be adjusted as needed, thereby precisely controlling the tension of the web. This design ensures that the web maintains appropriate tension throughout the entire processing process, preventing deformation or damage caused by insufficient or excessive tension. Both the first and second tensioning rollers 112, 115 can rotate about their respective central axes, and the second tensioning roller 115 can also move axially up and down. This enables the tensioning mechanism to automatically adjust to changes in web width and thickness, accommodating materials of varying specifications and enhancing the flexibility and applicability of the equipment.

A pushing member 25 is provided for lifting the coil to the locking member 22. The mounting seat 21 provides a stable support base. The locking member 22 ensures the stability and safety of the coil during the discharging process. The locking member 22 locks the first support rod 23 and supports the coil through the bearing, so that the coil can rotate smoothly around the central axis of the first support rod 23, reducing friction and wear. The meshing design of the first gear 27 and the second gear 28 makes it possible to control the rotation of the first gear 27 by locking the second gear 28, thereby realizing the discharging control of the coil. The pushing member 25 can lift the coil to the position of the locking member 22 through the hydraulic principle, realizing the automatic loading of the coil, reducing manual intervention and improving work efficiency.

When the waste extends out from between the first waste collecting roller 621 and the second waste collecting roller 622, the first waste collecting roller rotates by the tangential force of the waste movement. The first conveyor belt 611 is at the same height as the position of the product after the pressing and cutting is completed, ensuring that the product can be smoothly transferred from the pressing and cutting mechanism to the conveyor belt to avoid the product from falling or being damaged.

The first waste collecting roller 621 and the second waste collecting roller 622 rotate in opposite directions, which can effectively separate and collect the waste from the pressing and cutting mechanism. When the waste extends out from between the two rollers, the first waste collecting roller rotates by the tangential force of the waste movement to ensure the smooth collection of the waste.

[0042] The working principle of this embodiment is as follows:

[0043] A process of using a die-cutting machine that maintains tension, such as Figure 1 As shown, the coil is placed on the loading mechanism, and the coil rotates to discharge the material belt and enter the first tensioning roller mechanism. After that, the material belt is pushed on the first material belt support and pushed into the first tensioning roller mechanism, and then enters the edge pressing mechanism for edge pressing and forming, and enters the edge trimming mechanism for edge trimming and cutting out the product. The product enters the product collecting mechanism for collection. After the product is cut out, the material belt becomes waste and enters the waste collection mechanism. The tensioning mechanism tensions the material belt before entering the edge pressing process to prevent the material belt from deflecting, thereby ensuring the consistency of product size and product quality.
