Description

Technical Field

[0001] The invention relates to the technical field of die cutting, in particular to a circular knife asynchronous SCF die cutting material saving device and process. Background Art

[0002] Die cutting, in short, is a molding process that uses a die to punch materials to form specific shapes and specifications. There are many types of die-cut materials, including paper, plastic, metal foil, rubber, single-sided and double-sided tape, foam, optical film, protective film, gauze and other materials to meet the needs of different industries and products. During the die-cutting process, these materials are punched by the die to form parts with specific shapes and functions.

[0003] Among them, die-cutting equipment is an important part of the die-cutting process, which is mainly divided into two categories: one is a large-scale die-cutting machine specially used for carton and color box packaging; the other is a die-cutting machine used for precision electronic die-cutting products.

[0004] The die-cutting process usually includes the steps of arranging the cutter, loading the plate, setting the machine pressure, testing the die-cutting, adjusting the pressure, formally die-cutting, and clearing the waste. Among them, steel knife die-cutting is the most commonly used form of custom die-cutting, while circular knife die-cutting is suitable for die-cutting processing with different materials and precision requirements. With the increasing market requirements for the precision and quality of die-cut products, traditional circular knife die-cutting technology has gradually exposed some problems, which not only limit production efficiency, but also have a certain impact on the quality and cost of the final product.

[0005] Especially in the combination of SCF materials, this link often lacks precise guidance and positioning mechanisms in traditional circular die-cutting technology. During the combination process, due to the lack of high-precision control, the alignment between SCF materials is prone to deviation. This deviation may be small, but it will affect the quality and material saving effect of the final product, resulting in the product not meeting the design requirements. In addition, this inaccurate combination may also lead to waste in the die-cutting process and an increase in the defective rate, which not only increases production costs, but also prolongs the production cycle.

[0006] Therefore, it is necessary to provide a circular knife asynchronous SCF die-cutting material saving device and process to solve the above problems. Summary of the invention

[0047] Please refer to Figure 1-Figure 6 In an embodiment of the present invention, a circular knife asynchronous SCF die-cutting material saving device is provided, comprising:

[0048] A first feeding roller 1, used for feeding a first material body;

[0049] A screed plate 3 is used to receive the first material body, and a cutter 4 is provided in the space above the screed plate 3. The first material body can be cut into a plurality of unit material bodies by the cooperation between the screed plate 3 and the cutter 4;

[0050] A second feeding roller 7, used for feeding a second material body;

[0051] An asynchronous material unloading component 6 is used to receive a unit material body and slowly deliver the unit material body to the upper surface of the second material body, so that the unit material body and the second material body form an SCF material body;

[0052] The SCF material body is die-cut by the circular knife roller group 9 to form waste material and finished product, wherein the waste material is rolled up by the first winding roller 11 and the finished product is rolled up by the second winding roller 12;

[0053] The asynchronous unloading component 6 at least comprises a frame 61 and a slow-down component 66 , wherein the frame 61 has a slow-down passage extending vertically, through grooves 64 are formed on four sides of the frame 61 , and the slow-down component 66 is disposed in the through grooves 64 .

[0054] The implementation includes the following steps:

[0055] Step 1: The first feeding roller 1 starts to rotate and feeds the first material, which is then conveyed to the screed plate 3;

[0056] Step 2: The second feeding roller 7 starts to rotate and supplies the second material body; the second material body is conveyed to the downstream position of the asynchronous unloading component 6;

[0057] Step 3: The screed plate 3 receives the first material body from the first feeding roller 1 and performs a screed process on it. The cutter 4 on the screed plate 3 cuts the first material body according to a preset interval to form a plurality of unit materials.

[0058] Step 4: the asynchronous material unloading component 6 receives the unit material body and slowly delivers the unit material body to the upper surface of the second material body, so that the unit material body and the second material body form an SCF material body;

[0059] Step 5: The SCF material body continues to be transported forward, and when the SCF material body passes through the circular knife roller group 9, it is die-cut into a predetermined shape and size;

[0060] Step 6: The waste generated during the die-cutting process is rolled up by the first winding roller 11 , and the finished product is rolled up by the second winding roller 12 .

[0061] Among them, by setting up the asynchronous unloading component 6, the unit material body can be effectively guided to ensure that it can maintain a horizontal posture and slowly descend to the upper surface of the second material body. In this way, the combination of the two is more precise, so a smaller error value can be left when designing the parameters of the two, thereby improving the material saving effect.

[0062] More specifically, the asynchronous blanking component 6 further includes:

[0063] Two symmetrically arranged guide and limit plates 63, each guide and limit plate 63 comprising a guide portion and a limit portion, and the side of the limit portions close to each other is flush with the inner wall of the frame body 61;

[0064] a baffle 67 fixed to the frame 61, and a side of the baffle 67 close to the guide stopper plate 63 is flush with the inner wall of the frame 61;

[0065] Two symmetrically arranged slide plates 62 are slidably arranged in the frame 61 , and the upper surfaces of the slide plates 62 are flush with the upper surface of the frame 61 .

[0066] During implementation, when the unit material is conveyed to the asynchronous unloading assembly 6 by the leveling roller assembly 5, the unit material can be accurately positioned between the two limiting parts under the guidance of the guide part. Subsequently, the unit material continues to move until it is limited by the baffle 67. At this time, the two slides 62 move toward the outside of the frame 61 at the same time. At this time, the unit material moves downward under its own weight.

[0067] In order to make the unit material body move downward more smoothly, the slow-descent component 66 includes two symmetrically arranged slow-descent wheel groups, a belt 664 is connected for transmission between the two slow-descent wheel groups, and a micro-oscillation component 665 for micro-oscillating the belt 664 is also arranged between the two slow-descent wheel groups.

[0068] It should be noted that in the prior art, the movement control of the unit material body usually relies on the limit groove. Although this method can effectively limit the downward movement posture of the unit material body, it has obvious defects. Specifically, the sliding friction between the unit material body and the limit groove is a key issue. Since the surface characteristics of the unit material body are different (part of the surface exists originally, while the other part is formed by the cutter), this difference leads to different surface friction coefficients. This uneven friction coefficient increases the risk of the unit material body changing its posture during the downward movement, thereby affecting the accuracy and stability of the movement.

[0069] In order to overcome this defect, this embodiment adopts a new design idea. Here, the unit material no longer generates sliding friction with the limit groove, but forms static friction with the belt 664. Static friction has higher stability and controllability than sliding friction, because it can more effectively prevent the object from moving relative to the force direction. Therefore, when the unit material moves on the belt, its downward movement posture can be well maintained and will not change due to the uneven friction coefficient.

[0070] Furthermore, the descending slow component 66 is mounted on a mounting plate 65 , and the mounting plate 65 is fixed to the outside of the frame 61 , so that the side of the belt 664 close to the unit material body is flush with the inner surface of the frame 61 .

[0071] Furthermore, the slow-descent wheel group includes a ratchet 661 and a rotating wheel 662, the ratchet 661 is fixed on the mounting plate 65, the rotating wheel 662 is rotatably sleeved on the outside of the ratchet 661, and the inner wall of the rotating wheel 662 is hinged with a plurality of pawls 663 that cooperate with the ratchet 661, and a torsion spring is arranged between the pawl 663 and the rotating wheel 662.

[0072] It should be noted that due to the presence of the torsion spring, the pawl 663 can be pressed against the ratchet 661, thereby creating damping between the two. When the ratchet 661 rotates, under the action of the torsion spring, the belt will move slowly due to the damping, thereby achieving a slow descent of the unit material.

[0073] In this embodiment, the micro-oscillation component 665 includes:

[0074] An installation chamber 6651 in which a positioning member 6652 is fixed;

[0075] An elastic member 6653, one end of which passes through the positioning member 6652 and extends out of the installation compartment 6651;

[0076] A micro-oscillation wheel 6654 is rotatably disposed at one end of the elastic member 6653 and is used to support the belt 664;

[0077] The micro-oscillation motor 6655 is installed in the installation compartment 6651 using elastic rubber, and a vibration transmission rod 6656 is fixed to one end of the micro-oscillation motor 6655, and the vibration transmission rod 6656 is embedded in the elastic member 6653.

[0078] It should be noted that the micro-oscillation component 665 is not always turned on, but is only turned on when the posture of the unit material needs to be fine-tuned due to unexpected circumstances.

[0079] In this embodiment, the leveling plate 3 has a reinforcing plate 31 at a position corresponding to the cutting knife 4;

[0080] The upper surface of the screed plate 3 is provided with a screed roller assembly 5, which can play an auxiliary screeding role.

[0081] Furthermore, a first guide roller group 2 is provided between the first feeding roller 1 and the cutter 4, for horizontally guiding the first material body;

[0082] A second guide roller group 8 is provided between the second feeding roller 7 and the circular knife roller group 9, for guiding the second material body horizontally;

[0083] The waste is guided by the third guide roller group 10 and then wound up by the first winding roller 11 .

[0084] Based on this, in this embodiment, a circular knife asynchronous SCF die-cutting material saving process is also provided, comprising the following steps:

[0085] Step 1: The first feeding roller 1 starts to rotate and feeds the first material, which is then conveyed to the screed plate 3;

[0086] Step 2: The second feeding roller 7 starts to rotate and supplies the second material body; the second material body is conveyed to the downstream position of the asynchronous unloading component 6;

[0087] Step 3: The screed plate 3 receives the first material body from the first feeding roller 1 and performs a screed process on it. The cutter 4 on the screed plate 3 cuts the first material body according to a preset interval to form a plurality of unit materials.

[0088] Step 4: The asynchronous material unloading component 6 receives the unit material body and slowly delivers the unit material body to the upper surface of the second material body, so that the unit material body and the second material body form an SCF material body. In this way, the combination of the two is more accurate, so a smaller error value can be left when designing the parameters of the two, thereby improving the material saving effect;

[0089] Step 5: The SCF material body continues to be transported forward, and when the SCF material body passes through the circular knife roller group 9, it is die-cut into a predetermined shape and size;

[0090] Step 6: The waste generated during the die-cutting process is rolled up by the first winding roller 11 , and the finished product is rolled up by the second winding roller 12 .

[0091] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
