Description

Technical Field

[0001] The present invention relates to the field of die-cutting equipment, and particularly to a continuous die-cutting machine. Background Art

[0002] In the production process of label paper, it is necessary to cut the label paper. During the die-cutting process, due to the certain toughness of the label paper, there is a phenomenon that the label paper is not completely broken after die-cutting by the die-cutting machine, which affects the work efficiency. At the same time, during the die-cutting process, a large amount of waste materials such as cuttings are generated. The existing treatment method generally adopts a winding method to treat the waste materials. Since the width of the waste materials is generally small and the tensile resistance is weak, under the influence of the winding tension, the waste materials are prone to breakage. At this time, it is necessary for workers to manually wind the broken waste materials onto the winding roller again, which is rather cumbersome. At the same time, during this process, the winding roller keeps working, which easily causes the engineer's fingers to be caught in the machine, endangering the personal safety of the engineer. Summary of the Invention

[0005] Further, the demolding device is set to be spherical and is made of rubber material when the die-cutting knife moves upward inside the die-cutting knife.

[0006] Further, the feeding assembly includes a first driving member and a feeding roller; a first driving member is installed on the left side of the workbench; the output end of the first driving member is connected to a feeding roller for conveying the label paper.

[0007] Further, it further includes a fixator and an elastic member; a fixator is fixedly connected inside the housing, and the fixator is fixedly connected to the demolding device; an elastic member is fixedly connected inside the housing; the elastic member is fixedly connected to the fixator.

[0008] Furthermore, it also includes a flattening roller; a flattening roller for pre-flattening the label paper is rotatably connected to the holder.

[0009] Furthermore, the distance between the lowest point of the demolding device and the upper surface of the label paper is less than the distance between the lowest point of the flattening roller and the upper surface of the label paper.

[0010] Furthermore, it also includes side plates; side plates that can be opened and closed for cleaning waste are provided on the front side of the housing.

[0011] Furthermore, the waste winding system includes a transmission roller, a flattening roller, a first double-thread gathering roller, and a winding roller; a transmission roller is rotatably connected inside the housing; a flattening roller for flattening the label paper is rotatably connected inside the housing; a first double-thread gathering roller that can gather the waste towards the middle is rotatably connected inside the housing; a winding roller for winding the waste is rotatably connected inside the housing; the flattening roller is located to the left of the transmission roller; the first double-thread gathering roller is located to the right of the flattening roller; the winding roller is located above the first double-thread gathering roller; and the transmission roller and the flattening roller are connected by a belt pulley for transmission; the flattening roller and the first double-thread gathering roller are connected by a belt pulley for transmission; the first double-thread gathering roller and the winding roller are connected by a belt pulley for transmission.

[0012] Furthermore, the flattening roller can be replaced with a second double-thread gathering roller, and the threads on the second double-thread gathering roller have a reverse helix direction compared to the threads on the first double-thread gathering roller.

[0013] Furthermore, an inclined surface is provided on the knife pad.

[0014] The beneficial effects of the present invention are as follows: The present invention realizes a spherical demolding device made of rubber material. When the die-cutting is completed and the die-cutting knife moves upward, the demolding device continuously presses the die-cut finished product to separate it from the waste. At the same time, through the deformed and spherical demolding device, the contact area with the circular finished product is increased, and at the same time, the connecting edge between the circular finished product and the waste is evenly stressed, improving the separation efficiency and preventing cracks due to uneven stress.

[0015] By rotating the flattening roller, the pre-flattening of the label paper is realized, preventing the label paper from flying. At the same time, further through the extrusion of the label paper during die-cutting by the flattening roller, the tension of the label paper is increased, further effectively assisting die-cutting and preventing problems such as insufficient tension during die-cutting, inability to fully die-cut, or non-compliant circular finished products during die-cutting.

[0016] After the die-cutting is completed by the die-cutting knife, the demolding device continues to press the die-cut finished product of the label paper to prevent the label paper from not being cut off, affecting the work efficiency.

[0017] The label paper is smoothed by the flattening roller to prevent it from affecting the subsequent die-cutting, and then the first double-threaded gathering roller is used to twist the waste material along the threads on the first double-threaded gathering roller toward the middle of the first double-threaded gathering roller, that is, the waste material is twisted to a state similar to a twisted rope, thereby making the waste material more firm and less likely to break;

[0018] By arranging a second double-threaded gathering roller with a counter-thread to the first double-threaded gathering roller, the influence of the waste material twisting on the undie-cut label paper on the left side can be offset, thereby realizing rapid die-cutting and collecting waste materials.

[0033] The demolding device 6 is set to be spherical and made of rubber material; when the demolding device 6 moves downward to contact the knife pad 7, the contact end of the demolding device 6 with the knife pad 7 deforms and gradually shrinks into the die-cutting knife 5. When the die-cutting is completed and the die-cutting knife 5 moves upward, the demolding device 6 continuously presses the finished product after die-cutting to separate it from the waste. At the same time, through the deformed and spherical demolding device 6, the contact area with the circular finished product is increased, and the connecting edge between the circular finished product and the waste is uniformly stressed, improving the separation efficiency and preventing cracks due to uneven stress.

[0034] The material feeding assembly includes a first driving member 101 and a material feeding roller 102; the first driving member 101 is installed on the left side of the workbench 1, and the first driving member 101 is a motor; the output end of the first driving member 101 is connected to the material feeding roller 102; the label paper 4 is conveyed from left to right through the material feeding roller 102 driven by the first driving member 101. During this process, an external traction device is connected to realize the smooth transmission of the label paper 4.

[0035] It further includes a second driving member 201; a second driving member 201 for driving the die-cutting knife 5 to move up and down is fixedly connected inside the housing 2, and the second driving member 201 is an electric push rod; the die-cutting knife 5 is driven to move up and down by the second driving member 201 to realize the die-cutting process of the label paper 4.

[0036] It further includes a fixator 301 and an elastic member 302; the fixator 301 is fixedly connected inside the housing 2, and the fixator 301 is fixedly connected to the demolding device 6; the elastic member 302 is fixedly connected inside the housing 2, and the elastic member 302 is a spring; the elastic member 302 is fixedly connected to the fixator 301; the second driving member 201 drives the fixator 301 and the die-cutting knife 5 to move downward synchronously, the fixator 301 drives the demolding device 6 to move downward, when the demolding device 6 moves downward to contact the knife pad 7, the second driving member 201 drives the die-cutting knife 5 to continue moving downward, and at the same time compresses the elastic member 302 until the die-cutting knife 5 completes die-cutting, the second driving member 201 drives the die-cutting knife 5 to move upward, and at the same time the elastic member 302 rebounds, driving the fixator 301 to rebound, so that the demolding device 6 continues to squeeze the circular finished product after die-cutting of the label paper 4, preventing the problem that the label paper 4 is not cut off, which affects the work efficiency.

[0037] It further includes a flattening roller 303; the flattening roller 303 is rotatably connected to the fixator 301; the second driving member 201 drives the fixator 301 to move downward, driving the flattening roller 303 to move downward to contact the label paper 4, and generating a pressure between the flattening roller 303 and the label paper 4, and then driving the flattening roller 303 to rotate by the thrust generated when the feeding roller 102 conveys the label paper 4 from left to right, realizing the pre-flattening of the label paper 4, preventing the label paper 4 from flying, and at the same time, further squeezing the label paper 4 generated during die-cutting by the flattening roller 303, increasing the tension of the label paper 4, further effectively assisting die-cutting, and preventing problems such as insufficient tension during die-cutting, inability to completely die-cut or the circular finished product of die-cutting not meeting the standard.

[0038] The distance between the lowest point of the demolding device 6 and the upper surface of the label paper 4 is less than the distance between the lowest point of the flattening roller 303 and the upper surface of the label paper 4, so that before the die-cutting knife 5 performs die-cutting, the flattening roller 303 first contacts the label paper 4 and squeezes the label paper 4, causing the label paper 4 to generate a certain tension, preventing the problem of insufficient tension during subsequent die-cutting.

[0039] It further includes a side plate 3; the side plate 3 is arranged on the front side of the housing 2; by manually opening the side plate 3, the waste is taken out manually to realize the cleaning of the waste.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figure 1 、 Figure 2 and Figures 6 - 9As shown in the figure, the waste winding system includes a transmission roller 401, a flattening roller 402, a first double-thread gathering roller 403, and a material receiving roller 404. The transmission roller 401 is rotatably connected inside the housing 2. The flattening roller 402 is rotatably connected inside the housing 2. The first double-thread gathering roller 403 is rotatably connected inside the housing 2. The material receiving roller 404 is rotatably connected inside the housing 2. The flattening roller 402 is located to the left of the transmission roller 401. The first double-thread gathering roller 403 is located to the right of the flattening roller 402. The material receiving roller 404 is located above the first double-thread gathering roller. And the transmission roller 401 and the flattening roller 402 are connected by a belt pulley for transmission. The flattening roller 402 and the first double-thread gathering roller 403 are connected by a belt pulley for transmission. The first double-thread gathering roller 403 and the material receiving roller 404 are connected by a belt pulley for transmission. By the rotation of the transmission roller 401 driving the rotation of the flattening roller 402, the flattening of the label paper 4 is realized. Then, by the flattening roller 402 driving the rotation of the first double-thread gathering roller 403, the waste is gathered towards the center. Further, by the first double-thread gathering roller 403 driving the rotation of the material receiving roller 404, the winding of the waste is realized.

[0042] The flattening roller 402 can be replaced by a second double-thread gathering roller 40201, and the thread on the second double-thread gathering roller 40201 has a reverse helix direction to that on the first double-thread gathering roller 403. When the second double-thread gathering roller 40201 rotates, the rotational force applied to the label paper 4 is opposite to the rotational force applied to the label paper 4 by the first double-thread gathering roller 403, so as to realize the flattening of the label paper 4.

[0043] It further includes a third driving member 501. The third driving member 501 is installed inside the housing 2, and the third driving member 501 is a motor. The output end of the third driving member 501 is fixedly connected to the transmission roller 401.

[0044] Detailed description of the waste material winding process: In the initial die-cutting state, since the label paper 4 has wrinkles due to tension, in the initial process, after the right end of the label paper 4 is manually pulled onto the receiving roller 404, the flattening roller 402 is first used to smooth the label paper 4 to prevent it from affecting the subsequent die-cutting. After the traction is completed, the flattening roller 402 is replaced with the second double-threaded winding roller 40201. When the die-cutting is in progress, the waste material generated is wound up by the receiving roller 404. During the winding process, in order to prevent the waste material from breaking, the first double-threaded winding roller 403 is set , so that the waste is twisted along the threads on the first double-threaded gathering roller 403 toward the middle of the first double-threaded gathering roller 403, that is, the waste is twisted to a state similar to a twisted rope, thereby making the waste tighter and less likely to break. At the same time, since the waste is always connected to the undie-cut label paper 4 on the left side when it is rolled up, in order to prevent the twisting process of the waste from affecting the state of the undie-cut label paper 4 on the left side, a second double-threaded gathering roller 40201 with a counter-thread to the first double-threaded gathering roller 403 is set, thereby offsetting the influence of the waste twisting on the undie-cut label paper 4 on the left side, thereby achieving rapid die-cutting and waste collection.

[0045] An inclined surface 7001 is provided on the knife pad 7. When the finished product of the die-cut label paper 4 is transmitted to the bottom of the rotating flattening roller 402, the inclined surface 7001 increases the interval between the round finished product and the first double-threaded gathering roller 403 to prevent the round finished product from being rolled in when the first double-threaded gathering roller 403 rotates, causing the first double-threaded gathering roller 403 to be stuck and affect work efficiency.
