Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machines, and in particular to a straight-roller die-cutting machine. Background Art

[0002] A die-cutting machine is a device used to cut, crease, and process materials into specific shapes and sizes. It plays a key role in many industrial fields. The working principle is to apply pressure to the material so that the die acts on the material to achieve the molding of the material. It mainly relies on die-cutting knives (steel knives), hardware molds or steel wires (or templates carved from steel plates) to transfer pressure to materials such as paper, leather, plastic, and rubber. Under the action of pressure, the material is cut, creased, or hollowed out to obtain the desired shape and pattern.

[0003] The circular knife die-cutter is an important type of die-cutter. It is widely used in material processing in many industries and has unique advantages. Its working principle is to die-cut the material based on the relative movement of the circular knife roller and the bottom roller. First, the material to be die-cut is installed on the unwinding mechanism of the feeding device. Under the action of the tension control system, the material is conveyed between the circular knife roller and the bottom roller through the deviation correction device with stable tension. The circular knife roller rotates at high speed under power drive, and the knife on its circumference is closely matched with the bottom roller. When the material passes through, the knife applies pressure to the material during the rotation process and cuts the material according to the pre-set shape and size.

[0004] A circular knife die-cutting machine generally performs die-cutting operations on strip materials, and a guiding operation is required during the die-cutting. When installing guide rollers on existing die-cutting machines, there are different installation positions on the die-cutting machine. The guide rollers are installed at different positions according to needs, but this method is difficult to finely adjust to the required position. Due to the material of the die-cutting material, a slight change in its curvature may affect the life of the corresponding material itself and even the die-cutting quality due to changes in internal forces. Therefore, there is a special need for a die-cutting machine that can flexibly and accurately adjust the guide rollers to further improve the processing quality. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0025] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] like Figures 1 to 8 As shown, the present invention proposes a straight roller die-cutting machine, including a supporting plate body 1: two supporting plate bodies 1 are arranged relatively to each other; a die-cutting roller group 2 is arranged between the two supporting plate bodies 1, and the die-cutting roller group 2 includes a rotatable circular knife bottom shaft 21, a die-cutting lower roller 22 and a die-cutting upper roller 23, the die-cutting lower roller 22 is located above the circular knife bottom shaft 21, and the die-cutting upper roller 23 is located above the die-cutting lower roller 22; a guide assembly 3 is lifted and arranged on the supporting plate body 1, and the guide assembly 3 has two, and the two guide assemblies 3 are respectively located on both sides of the die-cutting roller group 2, and the guide assembly 3 includes: two first sliders 31, and the two first sliders 31 are respectively slidably arranged on the two supporting plate bodies 1, and the two first sliders 31 are opposite to each other, and the first slider 31 rises or falls after sliding; a locking member 32 is arranged on the first slider 31, and the locking member 32 is used to limit the position of the first slider 31; the two ends of the guide roller 33 are respectively rotatably arranged on the two first sliders 31.

[0028] In this embodiment, two supporting plates 1 arranged opposite to each other provide a stable frame foundation for the die-cutting machine. The die-cutting lower roller 22 and the die-cutting upper roller 23 cooperate to realize the die-cutting action of the material. The surface material is selected according to different die-cutting materials. For example, for soft materials such as paper and plastic film, a rubber or polyurethane coating layer is used, which can effectively cut and protect the surface of the material; for harder materials, a hard alloy or high carbon steel material is used.

[0029] The first slider 31 slides on the two support plates 1. Through the lifting movement of the first slider 31, the height of the guide roller 33 can be flexibly adjusted to meet the guiding requirements of materials with different guiding heights and angles, ensuring that the material maintains the correct position and posture before entering the die-cutting roller group 2, effectively reducing the deviation or distortion of the material, and improving the die-cutting accuracy. Compared with the traditional fixed-position guide device, it can significantly reduce the die-cutting defective rate caused by inaccurate guidance.

[0030] The locking member 32 cooperates with the first slider 31 to limit and fix the position of the first slider 31. During the operation of the equipment, the first slider 31 can be prevented from being displaced due to external factors such as vibration and impact, the position stability of the guide roller 33 is ensured, the material is always conveyed along the predetermined track, and the change of the internal force of the material caused by the change of the position of the guide roller 33 is avoided, thereby protecting the quality and life of the material and improving the consistency and stability of the die-cutting products.

[0031] Both ends of the guide roller 33 are mounted on the first slider 31 and can rotate flexibly. The material is selected according to the material characteristics. For example, rubber or polyurethane material can provide good friction and buffering performance to prevent scratches on the surface of the material and ensure stable transportation. The diameter and length of the guide roller 33 are designed according to the die-cutting machine format and the material width, which can effectively guide the material, reduce the tension fluctuation of the material during transportation, and make the material smoothly enter the die-cutting roller group 2 or make the material output from the die-cutting roller group 2, further improve the die-cutting quality, and reduce the die-cutting defects caused by unstable material transportation.

[0032] Furthermore, the support plate 1 has positioning scale lines 15 , which are distributed along the sliding direction of the first slider 31 . The positioning scale lines 15 are close to the first slider 31 , and are used to indicate the position of the first slider 31 .

[0033] In this embodiment, the positioning scale 15 distributed along the sliding direction of the first slider 31 and close to the first slider 31 provides the operator with an intuitive and accurate reference for the position of the first slider 31. When adjusting the height of the guide assembly 3, the operator does not need to use complex measuring tools. He only needs to observe the relative position of the first slider 31 and the positioning scale 15 to quickly and accurately adjust the guide assembly 3 to a predetermined height, which greatly shortens the equipment debugging time and improves the production preparation efficiency. In the production scenario where the die-cutting materials or product specifications are frequently changed, the height of the guide assembly 3 can be ensured to be consistent after each adjustment, effectively ensuring the dimensional accuracy and quality stability of the die-cutting products, reducing the generation of waste caused by the height adjustment error of the guide assembly 3, and reducing production costs.

[0034] This equipment has the characteristics of collaborative work among multiple seats and multiple workstations. This invention solves the problem of manual alignment between multiple seats and multiple workstations, and realizes the one-key alignment function for multiple workstations.

[0035] Specifically, in actual application scenarios, this die-cutting machine has a unique advantage, and it can set up multiple ones in succession for collaborative work. Since each die-cutting machine is equipped with a guide roller 33 that can accurately determine the position, these guide rollers 33 are like reliable "coordinate points", providing an accurate position reference basis for the entire collaborative work system. Based on this, each die-cutting machine is equipped with a die-cutting upper roller 23 with an automated lifting control system, which can be quickly and accurately adjusted to the corresponding position based on the position reference provided by the guide roller 33. Moreover, the entire adjustment process is extremely convenient, and precise alignment can be achieved through a simple one-button operation, which not only greatly improves the efficiency of adjustment and shortens the equipment debugging time, but also further ensures the position accuracy of each link in the die-cutting process, effectively improving the overall production quality and efficiency.

[0036] In addition, in order to meet the demand for smooth guiding, the die-cutting upper roller 23 and the guide roller 33 will maintain a relatively fixed positional relationship. According to the positioning mark 15, the installation of the guide roller 33 can be accurately positioned and memorized. That is, when the guide roller 33 needs to be replaced and installed, it can be installed and fixed to the corresponding position by observing the positioning mark 15. According to the position of the guide roller 33, the relative position of the die-cutting upper roller 23 can be determined, thereby achieving the function and effect of one-key alignment, which is very convenient.

[0037] Furthermore, the die-cutting machine has a front surface 41 , a rear surface 42 , a left surface 43 and a right surface 44 , and the front surface 41 , the rear surface 42 , the left surface 43 and the right surface 44 are all provided with positioning score lines 15 .

[0038] In this embodiment, positioning lines 15 are set on the front 41, the back 42, the left side 43 and the right side 44 of the die-cutting machine, which greatly improves the convenience and comprehensiveness of the operator to obtain the position information of the first slider 31. The positioning lines 15 in different directions cooperate with each other to form an all-round visual positioning network. For example, in a large production workshop, when an operator is changing materials and making preliminary adjustments on the front of the equipment, if he finds that the positioning lines 15 on the front are inconvenient to observe or are partially blocked, he can quickly observe the corresponding positioning lines 15 from the side or back to obtain the accurate position information of the first slider 31. This multi-directional positioning line 15 design is particularly important in a multi-person collaborative production environment. Quality monitoring personnel can check whether the position of the guide component 3 is correct from different angles, find potential problems in time and notify the operator to make adjustments. At the same time, during the maintenance and maintenance of the equipment, maintenance personnel can also observe the positioning lines 15 from all directions to determine whether the first slider 31 is displaced or loose due to long-term use, so as to repair and calibrate in time to ensure the normal operation of the equipment and the stability of the die-cutting quality.

[0039] Furthermore, it also includes an adjusting screw 51, which is rotatably set on the supporting plate body 1, and the adjusting screw 51 passes through the first slider 31. The adjusting screw 51 is threadedly connected to the first slider 31. After the adjusting screw 51 rotates, the first slider 31 slides.

[0040] In this embodiment, the adjusting screw 51 that is rotatably disposed on the support plate 1 and threadedly connected to the first slider 31 constructs a high-precision, stable and reliable position adjustment mechanism. When the adjusting screw 51 is rotated, based on the principle of threaded transmission, the rotational motion can be accurately converted into the linear sliding motion of the first slider 31. This adjustment method has high precision. The operator can achieve small and precise adjustments to the position of the first slider 31 by controlling the rotation angle and direction of the adjusting screw 51, thereby meeting the stringent requirements of different die-cutting processes on the height of the guide assembly 3. The precise adjustment function of the adjusting screw 51 can effectively ensure the high matching accuracy between the guide roller 33 and the die-cutting roller group 2, ensuring that the material is always in the best processing position during the die-cutting process, thereby improving the qualified rate and quality stability of the product, and the self-locking characteristics of the threaded connection enable the first slider 31 to be stably maintained at the set position after the adjustment is completed, and will not be displaced due to factors such as equipment vibration and external force impact, thereby ensuring the reliability and continuity of the die-cutting process.

[0041] Furthermore, the support plate body 1 has a first surface 11 and a second surface 12, and the first slider 31 slides on the first surface 11; the locking member 32 includes a pad 321, and the pad 321 slides on the second surface 12; a fastening screw 322 passes through the pad 321 and is threadedly connected to the first slider 31, and the fastening screw 322 is used to make the first slider 31 press or release the first surface 11.

[0042] In this embodiment, the fastening screw 322 that passes through the pad 321 and is threadedly connected to the first slider 31 is tightly and reliably connected to the first slider 31, and the thread adopts a fine pitch thread form to improve the self-locking performance and adjustment accuracy of the thread. During normal die-cutting production, by tightening the fastening screw 322, the first slider 31 can be tightly pressed on the first surface 11 of the support plate body 1. The friction between the pad 321 and the second surface 12 and the axial tension of the fastening screw 322 are used to effectively limit the freedom of movement of the first slider 31, preventing the position of the guide component 3 from being offset due to vibration, impact or other external interference factors during the operation of the equipment, thereby ensuring the accuracy and stability of the die-cutting process. When the position of the guide component 3 needs to be adjusted, it is only necessary to loosen the fastening screw 322, and the pad 321 can slide relatively freely on the second surface 12, driving the first slider 31 to adjust its position. After the adjustment is completed, the fastening screw 322 can be tightened again to fix the new position. This design not only meets the strict requirements of the position stability of the guide component 3 during the operation of the equipment, but also facilitates the operator to quickly and conveniently adjust the position of the guide component 3 in the case of equipment maintenance, process adjustment, etc., thereby improving the operability and adaptability of the equipment and reducing the time and labor costs required for equipment adjustment.

[0043] Furthermore, the first surface 11 has a plurality of limit slots 13 , which are evenly distributed along the sliding direction of the first slider 31 ; the first slider 31 has a limit block 311 , which is used to be stuck in the limit slots 13 .

[0044] In this embodiment, a plurality of limit slots 13 evenly distributed along the sliding direction of the first slider 31 on the first surface 11 cooperate with the limit block 311 on the first slider 31 to provide additional positioning and error prevention functions for the sliding of the first slider 31. During the sliding process of the first slider 31, the limit block 311 can be inserted into the limit slots 13 in sequence according to a predetermined trajectory, and the position of each limit slot 13 corresponds to a specific height or position parameter of the guide assembly 3, which enables the first slider 31 to not only achieve continuous sliding adjustment during the adjustment process, but also to accurately position and lock at a key position. On the one hand, this positioning method further improves the accuracy and repeatability of the position adjustment of the first slider 31, and can ensure that the guide assembly 3 always returns to the same predetermined position even in the case of multiple adjustments or operations by different operators, thereby ensuring the consistency and stability of the die-cutting process; on the other hand, the limit block 311 is stuck in the limit slot 13, which can effectively prevent the first slider 31 from excessive sliding due to unexpected external force impact or operational errors, and avoids the position of the guide assembly 3 deviating from the normal working range, thereby ensuring the safety and reliability of the equipment and reducing production interruptions and losses caused by equipment failure or misoperation.

[0045] The limit slot 13 cooperates with the positioning score line 15 to realize accurate positioning and installation of the guide roller 33, avoiding possible deviations, providing convenience for operators to accurately install, and being more conducive to the positioning and adjustment of the die-cutting upper roller 23, which is very convenient.

[0046] Furthermore, the support plate body 1 further has a limiting surface 14 , which is opposite to the first surface 11 , and the first sliding block 31 is located between the first surface 11 and the limiting surface 14 .

[0047] In this embodiment, the limiting surface 14 of the support plate body 1 is arranged opposite to the first surface 11 and limits the first slider 31 therebetween, effectively constraining the freedom of movement of the first slider 31. In the direction perpendicular to the sliding direction of the first slider 31, the limiting surface 14 plays a role of blocking and positioning, preventing the first slider 31 from lateral deviation or shaking due to uneven force or other reasons. This stable constraint structure ensures that the position accuracy of the guide roller 33 in the horizontal direction remains unchanged, so that when the material enters the die-cutting roller group 2 through the guide assembly 3, it can move along a precisely set straight line trajectory, avoiding the left and right deviation or distortion of the material during the conveying process, thereby improving the dimensional accuracy and shape consistency of the die-cutting product.

[0048] Furthermore, the adjusting screw 51 is rotatably and movably disposed on the supporting plate body 1 , and the adjusting screw 51 is located at one side of the first surface 11 . The adjusting screw 51 moves closer to or farther from the first surface 11 .

[0049] In this embodiment, the setting of the adjusting screw 51 moving closer to or farther away from the first surface 11 can, firstly, adapt to the change in the distance of the first slider 31 closer to or farther away from the first surface 11 after the fastening screw 322 tightens or loosens the first slider 31; secondly, after the fastening screw 322 is tightened to limit the position of the first slider 31, an upward force is given to the first slider 31 by rotating the adjusting screw 51, which can balance the gravity generated by the first slider 31 and the guide roller 33, so that the fastening screw 322 only bears axial tension, thereby improving the service life of the fastening screw 322, and reducing the load at the connection between the fastening screw 322 and the first slider 31, thereby reducing the complexity of the force and improving the service life.

[0050] Furthermore, the support plate body 1 has a second sliding block 52 which is slidably arranged. The second sliding block 52 is located above the guide roller 33 . The second sliding block 52 slides closer to or farther away from the first surface 11 . The adjusting screw 51 is rotatably arranged on the second sliding block 52 .

[0051] In this embodiment, the second sliding block 52 slides to achieve the adjustment screw 51 to move closer to or away from the first surface 11 .

[0052] Furthermore, both the front face 41 and the rear face 42 have a second surface 12 , and a positioning mark 15 is located on the second surface 12 ; the positioning mark 15 located on the second surface 12 is close to the pad 321 , and the pad 321 has a pointing mark 323 , and the pointing mark 323 faces the positioning mark 15 .

[0053] In this embodiment, the positioning scale lines 15 of the second surface 12 on the front 41 and the back 42 are close to the pad 321 and the pad 321 has a pointing scale line 323 facing the positioning scale line 15, which provides a convenient and accurate positioning reference method for the operator when observing the position of the pad 321. In actual operation, since the pad 321 may partially block the first slider 31, it becomes difficult to directly observe the relative position of the first slider 31 and the positioning scale line 15. The existence of the pointing scale line 323 allows the operator to indirectly determine whether the position of the first slider 31 is accurate by simply observing the alignment of the pointing scale line 323 on the pad 321 and the positioning scale line 15 on the second surface 12. This design improves the efficiency and accuracy of obtaining positioning information under specific observation conditions, reduces positioning errors caused by inconvenient observation, and further ensures the accuracy and reliability of the position adjustment of the guide component 3. At the same time, this simple and intuitive positioning indication method also reduces the operating difficulty and labor intensity of the operator. Even less experienced operators can quickly and accurately complete the position adjustment operation of the guide component 3, thereby improving production efficiency and ease of use of the equipment, and helping enterprises reduce the cost increase caused by personnel training and operating errors.

[0054] Furthermore, a plurality of limit slots 13 correspond to the positioning scale lines 15 respectively.

[0055] In this embodiment, a plurality of limit slots 13 correspond to the positioning scale lines 15, respectively, further enhancing the accuracy and reliability of the position adjustment of the guide assembly 3. When the height of the guide roller 33 needs to be adjusted for equipment debugging or process changes, the operator can quickly determine the approximate target position range based on the positioning scale lines 15, and then achieve precise positioning through the cooperation of the limit card block 311 on the first slider 31 and the corresponding limit slot 13. This dual positioning mechanism not only makes the adjustment process more intuitive and convenient, and reduces the position deviation caused by the operator's misjudgment or unskilled operation, but also after the equipment has been running for a long time or has been impacted by external forces, even if the first slider 31 is slightly displaced, the engagement of the limit slot 13 and the limit card block 311 can quickly restore it to the preset accurate position, ensuring that the relative position relationship between the guide roller 33 and the die-cutting roller group 2 always remains stable.

[0056] Further, refer to Figure 8As shown, it also includes a guide wheel 61, a guide rope 62 and a counterweight 63. The counterweight 63 is set on the support plate body 1 for lifting and sliding. The guide wheel 61 is rotatably set on the support plate body 1. One end of the guide rope 62 is connected to the first slider 31, and the other end is connected to the counterweight 63 after being guided by the guide wheel 61.

[0057] In this embodiment, the gravity of the counterweight 63 can balance the gravity of the first slider 31 (including the guide roller 33) after the guide rope 62 changes direction, so that the force of the first slider 31 in the vertical direction remains balanced, which has many advantages. On the one hand, the fastening screw 322 only needs to bear the locking tension, and does not need to bear the force in other directions, so it is not easy to loosen, and the service life is improved; on the other hand, when the height of the first slider 31 is adjusted by rotating the adjustment screw 51, since the vertical force of the first slider 31 is balanced by the counterweight 63, the adjustment of the adjustment screw 51 will be very easy, reducing the adjustment burden and the damage to the adjustment screw 51 caused by the gravity of the first slider 31, which is conducive to fine and easy adjustment, greatly improving the operating experience and reducing the adjustment force.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
