Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die cutting, in particular to a die cutting plate with a push-back structure. Background Art
[0002] The die-cutting plate is an important tool used in the die-cutting process to cut paper, plastic film, cardboard and other materials. The outline of the graphic to be cut is made on the substrate using a wooden board, and a knife strip with a sharp blade is embedded in the wooden board. During the die-cutting process, the die-cutting plate is installed on the die-cutting machine. The machine applies pressure to place the paper, cardboard, etc. under the pressure surface. When the die-cutting machine is pressed down, the knife strip acts directly on the cardboard to cut the cardboard into the corresponding contour shape. The die-cutting plate is widely used in packaging, printing and other industries, and is often used for batch production of packaging boxes, trademarks, calendars, paper products, plastic products and other products of specific shapes.
[0003] When the die-cutting knife is cutting, the knife strip cuts into the cardboard under pressure, and there is friction between the cut surface of the cardboard and the blade, which makes it impossible to effectively separate the cardboard and the knife strip. As a result, when the die-cutting knife is lifted, the cut cardboard will clamp the knife strip and be lifted together with the knife strip. During the lifting process, the cut cardboard is pulled, resulting in creases or tears, thereby affecting the cutting quality. At the same time, the cut cardboard clamped by the knife strip requires manual intervention to separate it. Manual separation is easy to control the strength, and excessive force can also easily cause the cardboard to be torn and damaged.
[0004] In view of this, we propose a die-cutting knife plate with a push-back structure to solve the existing problem. Utility Model Content
[0005] The purpose of the present invention is to provide a die-cutting plate with an ejection structure to solve the problems raised in the above background technology.

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example
[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention proposes a die-cutting plate with a push-back structure, comprising:
[0025] A top plate 1, one end of the bottom of the top plate 1 is connected to a bottom plate 2;
[0026] The bottom plate 2 has a cutting plate 3 installed at one end of the bottom of the bottom plate 2. The bottom surface of the cutting plate 3 is provided with a contour to be cut, and a knife strip 31 is installed on the contour.
[0027] The guide rod 6 has one end which is movably passed through the top plate 1, the bottom plate 2 and the knife plate 3 in sequence and is connected to the ejection plate 4. A limit assembly 61 is provided on the body of the guide rod 6 to limit the movable stroke of the guide rod 6.
[0028] The reset assembly 5 is installed on the guide rod 6 and is used to push the limit assembly 61 to reset the guide rod 6.
[0029] Furthermore, through holes are correspondingly provided on the top plate 1, the bottom plate 2 and the cutting plate 3 along the same axis, through which the guide rod 6 can pass freely. A first guide sleeve 13 is provided between the top plate 1 and the guide rod 6, and a second guide sleeve 21 is provided between the bottom plate 2 and the guide rod 6.
[0030] Furthermore, a support column 11 is provided at the bottom of the top plate 1 , and the bottom end of the support column 11 is fixedly connected to the bottom plate 2 . A plurality of connection grooves 12 for connecting die-cutting equipment are provided on the end surface of the top plate 1 .
[0031] Furthermore, the limiting assembly 61 is a limiting ring disposed around the rod body of the guide rod 6 and is located between the reset assembly 5 and the base plate 2 .
[0032] Furthermore, the reset component 5 is a compressible spring and the spring is sleeved on the outer periphery of the guide rod 6 , the top end of the reset component 5 abuts against the bottom surface of the top plate 1 , and the bottom end of the reset component 5 abuts against the limit component 61 .
[0033] Furthermore, a buffer assembly 41 is connected to the bottom of the ejection plate 4 .
[0034] Furthermore, a concave receiving groove 32 is provided at one end of the bottom surface of the cutting plate 3 , and the shape of the receiving groove 32 corresponds to the outer contour of the ejection plate 4 .
[0035] Furthermore, the depth of the accommodating groove 32 matches the sum of the thicknesses of the ejection plate 4 and the buffer assembly 41 .
[0036] The working principle of a die-cutting plate with a retraction structure based on embodiment one is: in the initial state, the reset component 5 is in a non-compressed state, the top end of the reset component 5 is against the top plate 1, and the bottom end is against the limit component 61, and under the action of elastic force, the bottom end of the limit component 61 is against the top surface of the bottom plate 2, so that the retraction plate 4 at the bottom of the guide rod 6 and the buffer component 41 connected to the bottom end face of the retraction plate 4 protrude from the bottom end face of the die-cutting plate 3.
[0037] During the cutting process, the cutting machine pushes the top plate 1 downward, thereby driving the bottom plate 2 and the knife plate 3 to move toward the cardboard to be cut. As the cutting machine is pressed down, the ejector plate 4 first contacts the cardboard to be cut and is subjected to the reverse force of the cardboard, causing the guide rod 6 to reversely compress the reset component 5 through the limit component 61. When the ejector plate 4 and the buffer component 41 gradually retract into the accommodating groove 32, the knife strip 31 set at the bottom of the knife plate 3 also gradually cuts into the cardboard. In this process, the buffer component 41 plays a buffering role, reducing the direct impact of the ejector plate 4 on the cardboard, and protecting the cardboard from indentation. As the cutting machine is further pressed down, until the knife strip 31 completely cuts into the cardboard, the cutting action is completed.
[0038] After the cutting is completed, the cutting machine releases the pressure and gradually drives the knife plate 3 to rise. At this time, the reset component 5 uses the elastic force to push the guide rod 6 through the limit component 61 to drive the ejection plate 4 to move downward. Under the action of the reset component 5, the ejection plate 4 and the buffer component 41 connected to the bottom thereof gradually separate from the accommodating groove 32 and push downward to contact the cut cardboard. When the ejection plate 4 contacts the cut cardboard, the cutting machine gradually rises, which still exerts downward pressure on the reset component 5. The reset component 5 cannot instantly return to the extended state, causing the reset component 5 to exert elastic force on the limit component 61 downward. The force is then pushed to drive the guide rod 6 to drive the ejection plate 4 to gradually push the cardboard away from the knife strip 31, so that the cardboard and the knife strip 31 are automatically, smoothly and slowly separated during the retraction process of the cutting machine, thereby avoiding the problem that the cardboard is easily clamped by the knife strip 31 and causes tearing when the die-cutting knife plate is lifted. The buffer component 41 is provided at the bottom of the ejection plate 4, which not only reduces the direct impact of the ejection plate 4 on the cardboard, but also ensures that the cardboard will not be damaged during the ejection process. As the ejection plate 4 continues to move downward under the action of the reset component 5, the cardboard is completely ejected, so that the knife strip 31 is separated from the cut cardboard.
