Description

Technical Field

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

[0002] Currently, there are two main types of post-press die-cutting equipment commonly used in the printing and packaging industry. Manual die-cutters are inefficient and unsafe, making them widely used in small-scale workshops. Automatic die-cutters offer advantages such as high efficiency and enhanced safety, making them primarily used by large-scale printing and packaging plants. With rising labor costs and the country's increasing emphasis on safety, efficient and safe automated equipment is becoming increasingly popular. The trend is for automatic die-cutters to replace manual ones, which is crucial for the survival and development of printing and packaging plants.

[0003] Flatbed die-cutting machines are widely used in the packaging and printing industry. They work by die-cutting paper through the collision of a die plate and a base plate. Fully automatic die-cutting machines are constructed with two platforms: the die plate is mounted on the upper platform, and the base plate is mounted on the lower platform. When the machine is turned on, the upper and lower platforms repeatedly collide with each other, pressing each sheet of paper against the platforms as it passes through, achieving the desired die-cutting effect. During operation, fully automatic die-cutting machines require an operator to install the die plate and base plate. Installation requires that the die plate and base plate are perfectly aligned to ensure accurate die-cutting and indentation, i.e., high precision. If the die plate and base plate are not aligned, the indentation lines on the paper will be distorted or even broken during the pressing process, rendering the entire sheet useless. In this case, production must be stopped, and the operator must re-fix the die plate and base plate to ensure they are aligned perfectly. However, this process often comes with numerous drawbacks. First, production stops, requiring significant time for readjustment, which reduces both efficiency and output. Second, readjustment is cumbersome, requiring the operator to pull the entire upper plate frame securing the die plate from the machine, loosen the screws securing the plate frame, readjust the position, and then tighten the screws again. Sometimes, repeated attempts are required to find the perfect, consistent position, increasing the workload and the skill level required of the operator. Summary of the Invention

Thus, features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0066] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0067] Please refer to Figure 1 , in a specific embodiment, the present invention provides a flat die-cutting machine, which includes: an upper platform, a lower platform 5, a knife die plate mounted on the upper platform, and a bottom die plate mounted on the lower platform;

[0068] The bottom template includes a base plate 1 formed of a thick steel plate, a positioning plate 2 formed of a thin steel plate, and a positioning mechanism 3; wherein,

[0069] The adjustment plate 2 is stacked on the base plate 1, and a plurality of connection holes are provided on the two correspondingly. The connection holes of the adjustment plate 2 have a larger aperture than the connection holes of the base plate 1. The base plate 1 and the adjustment plate 2 can be fixed by fasteners.

[0070] The positioning mechanism 3 is connected to the positioning plate 2, and its positioning end is in contact with the substrate 1, and is used to adjust the position of the positioning plate 2 relative to the substrate 1 along the left-right direction and / or the front-back direction;

[0071] The lower platform is provided with a positioning mechanism for fixing the position of the substrate 1 on the lower platform.

[0072] In the flat die-cutting machine provided in this embodiment, the upper platform and the knife die plate installed thereon can be the same as those in the prior art, and the present invention will not elaborate on them here. As for the lower platform and the bottom die plate: the present invention designs the bottom die plate into a structure of two steel plates stacked up and down, wherein the lower steel plate is thicker and is the above-mentioned base plate 1, which serves as a positioning reference, and its position is fixed by the positioning mechanism of the positioning mechanism on the lower platform; the upper steel plate is thinner and is the above-mentioned adjustment plate 2, which can be fine-tuned relative to the base plate 1 in the front-back and / or left-right directions through the adjustment mechanism 3, playing the role of adjustment, and is used to align the position of the knife die plate; the adjustment end of the adjustment mechanism 3 contacts the base plate 1, and by adjusting the position of the adjustment end, the position adjustment of the adjustment plate 2 relative to the base plate 1 in the front-back and / or left-right directions is achieved. The base plate 1 and the adjustment plate 2 can be fixed by connecting holes, and the diameter of the connecting hole of the adjustment plate 2 is larger than the diameter of the connecting hole of the base plate 1, thereby ensuring that the two can still be fixed by fasteners after the position of the adjustment plate 2 is fine-tuned.

[0073] When the flat die-cutting machine provided by the embodiment of the present invention needs to calibrate the positions of the cutting plate and the bottom plate, the cutting plate portion does not need to be operated. Instead, only the position of the adjusting plate 2 in the bottom plate needs to be adjusted. The specific operation process is as follows:

[0074] Fix the base plate 1 and the adjustment plate 2 with fasteners;

[0075] The substrate 1 is fixed on the lower platform 5 through the positioning mechanism of the lower platform. At this time, the position of the substrate 1 is fixed under the limiting action of the positioning mechanism;

[0076] Remove the fasteners between the base plate 1 and the adjustment plate 2, adjust the position of the adjustment end of the adjustment mechanism 3, and fine-tune the position of the adjustment plate 2 relative to the base plate 1 in the left-right direction and / or the front-back direction until it is aligned with the knife plate;

[0077] Fix the adjustment end position of the adjustment mechanism 3; fix the base plate 1 and the adjustment plate 2 again by fasteners to ensure that the position does not change when the machine is running; thus, the entire template position correction process can be completed.

[0078] From the above content, it can be seen that the position correction of the knife plate and the bottom plate by using the flat die-cutting machine provided by the present invention is simple and quick to operate, saves labor, helps to improve the working efficiency of the whole machine, and increases production.

[0079] In the flat die-cutting machine provided in the embodiment of the present invention, a positioning mechanism is provided on the lower platform, which is used to fix the position of the substrate 1. As a preferred embodiment of the present invention, the positioning mechanism includes:

[0080] The first positioning edge 51 and the first pressing mechanism 52 are arranged on the left and right sides of the lower platform 5, and the left and right sides of the substrate 1 are limited by the first positioning edge 51 and the first pressing mechanism 52.

[0081] The second positioning edge and the second pressing mechanism are arranged on the front and back sides of the lower platform, and the front and back sides of the substrate 1 are limited by the second positioning edge and the second pressing mechanism.

[0082] In the operation of fixing the position of the substrate 1, the substrate 1 (together with the positioning plate 2) is placed on the lower platform 5, and the two adjacent sides are respectively arranged on the first positioning edge and the second positioning edge, and then the first pressing mechanism and the second pressing mechanism are adjusted, so that the position of the substrate 1 on the lower platform 5 is fixed, and the subsequent positioning operation is facilitated.

[0083] In the embodiment, the first pressing mechanism 52 is a first air cylinder, and the second pressing mechanism is a second air cylinder; the extension end of the first air cylinder abuts against one side of the left and right sides of the substrate 1; and the extension end of the second air cylinder abuts against one side of the front and back sides of the substrate 1. The air cylinder is used as the pressing mechanism, which has the advantages of flexible control and simple operation. Those skilled in the art can understand that the above-mentioned pressing mechanism can also use other structures, such as springs.

[0084] In addition, in order to facilitate the installation and removal of the substrate 1 on the lower platform, a handle 11 is preferably arranged on the substrate 1, please refer to Figure 2 and Figure 3 , the handle 11 is arranged on the side of the substrate 1 abutting against the first air cylinder or the second air cylinder. That is, the handle 11 is arranged on the side of the substrate 1 not contacting the first positioning edge and the second positioning edge. Further, the handle 11 is detachably connected with the substrate 1. More preferably, the handle 11 is a downwardly bent structure, thereby avoiding the interference between the position of the handle 11 and the position of the positioning plate.

[0085] In order to facilitate the installation and removal of the substrate 1 on the lower platform, the substrate 1 preferably has an auxiliary rolling part 12 on the side opposite to the handle 11. The auxiliary rolling part 12 makes the movement of the substrate 1 on the lower platform a rolling friction, greatly reducing the difficulty of moving the substrate 1 on the lower platform, saving manpower and material resources. In order to optimize the labor-saving effect, those skilled in the art can select the number of auxiliary rolling parts 12 according to the specific structure of the auxiliary rolling part 12 and the installation space. In the embodiment, two auxiliary rolling parts 12 are installed on the substrate 1.

[0086] Specifically, please refer to Figure 4 , the auxiliary rolling part 12 can include a wheel seat 13, a supporting rod 14 and a deep groove ball bearing 15;

[0087] See Figure 5 and Figure 6 The wheel seat 13 includes: a base; the base extends in the horizontal direction to form a left horizontal wing 131 and a right horizontal wing 132; the base is formed with a mounting notch 133 in the vertical direction (in order to facilitate understanding of the wheel seat structure, Figure 5 The wheel seat is rotated upward 90° from its normal use position, so the mounting notch 133 in this figure is arranged horizontally); the support rod 14 is fixed horizontally in the mounting notch 133; the inner ring of the deep groove ball bearing 15 is connected to the support rod 14 and is located in the mounting notch 133;

[0088] The base plate 1 is formed with two outwardly extending fixed platforms on the side opposite to the handle 11; a space for accommodating the base is formed between the two fixed platforms; the left horizontal wing 131 and the right horizontal wing 132 are respectively mounted on the two fixed platforms and fixed by fasteners; the bottom surface of the deep groove ball bearing 15 is flush with the bottom surface of the base plate 1.

[0089] During installation, the left and right horizontal wings 131, 132 of the wheel seat 13 are placed on the two fixed platforms of the base plate 1. The wheel seat 13 and the fixed platforms are then tightened and secured using screws or other fasteners. Thus, when moving the base plate 1, the handle 11 can be slightly lifted to allow the deep groove ball bearing 15 to contact the lower platform surface, thus moving the base plate 1 with minimal effort. Those skilled in the art will appreciate that the deep groove ball bearing 15 can also be replaced by a rolling element such as a roller.

[0090] In the flatbed die-cutting machine provided by the present invention, the positioning mechanism preferably employs an adjusting screw structure, wherein the distal end of the adjusting screw contacts the side surface of the substrate. Specifically, by rotating the adjusting screw, the adjusting screw abuts against the substrate, which remains stationary. The adjusting screw then moves, driving the adjusting plate to adjust its position, thereby achieving the positioning function.

[0091] Specifically, the positioning mechanism includes positioning units respectively arranged on the front, back, left side and right side of the positioning plate; each positioning unit includes an adjustment base and an adjustment screw;

[0092] The adjustment base is connected to the corresponding side of the adjustment plate; the adjustment base is provided with an internal screw hole perpendicular to the corresponding side of the base plate, the adjustment screw is screwed into the internal screw hole, and the end of the adjustment screw contacts the corresponding side of the base plate.

[0093] Therefore, when the positioning plate needs to be fine-tuned backward, the adjustment screw on the adjustment base located on the front of the positioning plate is turned to move the adjustment screw toward the baseplate. The baseplate is then fixed, and the adjustment screw drives the positioning plate backward under the reaction force of the baseplate. Adjustment in other directions is similar. After the positioning plate is adjusted, the adjustment screw is fixed with a nut, and the positioning plate and baseplate are then secured with screws or other fasteners.

[0094] As a preferred embodiment of the present invention, see Figures 7 to 10 , there are two positioning mechanisms 3, which are arranged on opposite sides of the positioning plate 2; a rectangular notch 16 is opened on the corresponding side of the substrate 1, and the rectangular notch 16 is formed by a first surface 16a parallel to the side surface and two oppositely arranged second surfaces 16b perpendicular to the side surface;

[0095] Each of the positioning mechanisms 3 includes:

[0096] The positioning base includes a first positioning base 31 arranged in a direction parallel to the side surface, and two second positioning bases 32 extending outward in a vertical direction at the front and rear ends of the first positioning mechanism 3; the first positioning base 31 is provided with a first positioning screw hole perpendicular to its arrangement direction; the two second positioning bases 32 are provided with second positioning screw holes perpendicular to the direction of the first positioning screw hole; the positioning base is located in the rectangular notch 16 of the base plate 1, and the top surface of the positioning base is connected to the positioning plate 2;

[0097] A first adjusting screw 41 is screwed into the first adjusting hole, with its distal end in contact with the first surface 16a of the base plate 1;

[0098] The two second adjusting screws 42 are respectively screwed into the two second adjusting screw holes, and the ends thereof are respectively in contact with the second surface 16 b of the base plate 1 .

[0099] This embodiment, similar to the positioning mechanism in the previous embodiment, also uses adjustment screws to adjust the position of the positioning plate. However, in this embodiment, only the positioning mechanism 3 needs to be installed on both sides of the positioning plate 2, further facilitating positioning operations. To adjust the front-to-back position of the positioning plate 2, the first adjustment screw 41 or the second adjustment screw 42 is simply turned. To adjust the left-to-right position, the first adjustment screw 41 on one side or the other is simply turned, resulting in a simple and quick operation.

[0100] The present invention also provides a flat die-cutting method, which comprises the following steps:

[0101] a) Template calibration

[0102] Using the flat die-cutting machine provided in the above embodiment, the base plate and the adjustment plate are fixed by fasteners; the base plate is fixed on the lower platform by the positioning mechanism of the lower platform;

[0103] Remove the fasteners between the base plate and the adjustment plate, adjust the position of the adjustment end of the adjustment mechanism, and fine-tune the position of the adjustment plate relative to the base plate in the left-right direction and / or the front-back direction until it is aligned with the cutting plate; fix the position of the adjustment end of the adjustment mechanism; fix the base plate and the adjustment plate again with the fasteners, and the calibration is completed;

[0104] b) Feed the paper into the flatbed die-cutting machine for die-cutting.

[0105] As can be seen from the above, in the flat die-cutting machine provided by the embodiment of the present invention, the bottom template is designed as a two-plate structure stacked up and down, wherein the lower steel plate is thicker and serves as the base plate, which acts as a positioning reference, and its position is fixed by the positioning mechanism of the positioning mechanism on the lower platform; the upper steel plate is thinner and serves as an adjustment plate, which can be fine-tuned in the front-back and / or left-right directions relative to the base plate by the adjustment mechanism, playing the role of adjustment, and is used to align with the position of the knife plate; the base plate and the adjustment plate can be fixed by connecting holes, and the hole diameter of the connecting hole of the adjustment plate is larger than the hole diameter of the connecting hole of the base plate, thereby ensuring that the two can still be fixed by fasteners after the position of the adjustment plate is fine-tuned. When the flat die-cutting machine provided by the embodiment of the present invention is used, when the position of the knife plate and the bottom template needs to be calibrated, the knife plate part does not need to be operated, and the position of the adjustment plate only needs to be adjusted by the adjustment mechanism. Therefore, the flat die-cutting machine provided by the present invention is used to calibrate the position of the knife plate and the bottom template, which has the advantages of simple and fast operation, saving labor, and helping to improve the working efficiency of the entire machine and increase production.
