Description

Technical Field

[0001] This application relates to the field of printing and packaging technology, specifically to an adjustment device for a waste removal structure and a waste removal die-cutting machine. Background Technology

[0002] Die-cutting is one of the most common processes in packaging printing. Essentially, it involves using a die-cutting blade to create a die-cutting plate according to the requirements of the product. Under pressure, the printed material or other coiled blanks are cut into the desired shape or with the required slits. After die-cutting, the material enters a waste removal section to clean away the material outside the cut shape or slits, leaving only the desired shape. Due to differences in paper size, the required waste removal and finished product cleaning tools vary. Waste removal refers to removing the material outside the cut shape or slits, while finished product cleaning refers to removing the material outside the cut shape or slits, leaving only the desired shape. When using smaller sheets of paper for production, smaller waste removal and finished product removal tools will have gaps with the machine in the paper feeding direction. Adjustment devices are used to fill these gaps between the die-cutting structure and the waste removal structure or between the waste removal structure and the finished product removal structure, to prevent die-cut printed materials or other coiled blanks from falling into the gaps, thereby affecting subsequent production efficiency.

[0003] In existing technologies, a manual adjustment device for the cleaning structure is generally used. By unlocking and locking the handle, then pulling the handle, the mop is moved to the appropriate position, and then the handle is locked. However, manual adjustment is time-consuming and labor-intensive, and has a low degree of automation. Summary of the Invention

[0031] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, top, bottom, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0032] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Figure 1 The diagram shown is an overall schematic diagram of an adjustment device provided in an embodiment of this application; as follows: Figure 1 As shown, the adjustment device is set between the waste removal structure and the die-cutting structure or between the waste removal structure and the finished product structure. The adjustment device includes: a movable plate 1; a sliding component 2, one end of the movable plate 1 is set on the sliding component 2; and a driving component 4, which is fixedly connected to the sliding component 2. The driving component 4 drives the movable plate 1 to move along the direction of the sliding component 2, thereby adjusting the relative position of the movable plate 1 and the waste removal structure.

[0035] Specifically, an adjustment device is set between the waste removal structure and the die-cutting structure, or between the waste removal structure and the finished product structure. Due to the different paper sizes, the required waste removal and finished product tools also vary in size. When using smaller paper for production, smaller waste removal and finished product tools are also selected, which will result in gaps between the waste removal structure and the die-cutting structure, or between the waste removal structure and the finished product structure. These gaps will cause instability in the conveying process. Therefore, in order to ensure the stability of printed materials or other coiled blanks during the conveying process and avoid affecting subsequent production efficiency and quality, this application sets up a drive component 4 and a sliding component 2. When the paper size to be die-cut is small, the drive component 4 drives the sliding component 2 to move closer to the waste removal structure, thereby driving the movable plate 1 to move closer to the waste removal structure. This achieves automatic adjustment of the adjustment device size, improves the degree of automation, and reduces manual labor.

[0036] Figure 2 The diagram shown is a connection schematic of the drive assembly and sliding assembly of an adjustment device according to an embodiment of this application; as shown Figure 2 As shown, combined with Figure 1 The drive assembly 4 includes: a motor bracket 41; a servo motor 42, which is mounted on the motor bracket 41; and a coupling 43, one end of which is connected to the output end of the servo motor 42.

[0037] In this embodiment, the servo motor 42 is fixedly connected to the motor bracket 41, which supports the servo motor 42. The output end of the servo motor 42 is connected to the coupling 43. The servo motor 42 provides power to drive the coupling 43 to rotate, thereby moving the position of the movable plate 1.

[0038] In one possible implementation, the adjustment device further includes a moving component 7, which includes a lead screw nut 71 and a lead screw 72. One end of the lead screw 72 is fixedly connected to the coupling 43, and the other end of the lead screw 72 is engaged with the lead screw nut 71.

[0039] Specifically, one end of the lead screw 71 is connected to the coupling 43, and the other end of the lead screw 72 is engaged with the lead screw nut 71. When the servo motor 42 provides power, it drives the coupling 43 to rotate, thereby driving the lead screw nut 71 to move along the lead screw 72.

[0040] It should be understood that in this implementation, the lead screw 72 is preferably a trapezoidal lead screw. The trapezoidal lead screw is low in cost and has self-locking properties, which facilitates the positional movement of the lead screw nut 71 along the lead screw 72.

[0041] In one possible implementation, the sliding assembly 2 includes: a first bracket 21, one end of the movable plate 1 is fixedly connected to the first bracket 21, and a lead screw nut 71 is fixedly connected to one side of the first bracket 21; a linear guide rail 22, one end of which is fixedly connected to the motor bracket 41, and the other end of which is connected to the die-cutting structure; and a slider 23, one end of which is slidably connected to the linear guide rail 22, and the other end of which is fixedly connected to the first bracket 21. Specifically, since the slider 23 is fixedly connected to the first bracket 21, and the lead screw nut 71 is also fixedly connected to the first bracket 21, when the servo motor 42 drives the coupling 43 to rotate, it drives the lead screw 73 and the lead screw nut 72 to move. The lead screw nut 72 then drives the first bracket 71 and the slider 23 to move. The slider 23 is slidably connected to the linear guide rail 22, and thus the slider 23 moves along the linear guide rail 22, thereby enabling the movable plate 1 to move along the linear guide rail 22.

[0042] Figure 3 The diagram shown is a schematic structural diagram of the guide assembly of an adjustment device according to an embodiment of this application; as shown Figure 3 As shown, the guide assembly 3 includes a second bracket 31, which is fixedly connected to one end of the movable plate 1 and is arranged perpendicularly to the movable plate 1; a guide rail 32, which is arranged at one end of the second bracket 31 near the movable plate 1; and a bearing 33, which is mounted on the guide rail 32.

[0043] It should be understood that in this embodiment, the guide component 3 moves the movable plate 1 along the moving direction of the moving component 3. One end of the movable plate 1 is fixed on the first bracket 21, and the other end of the movable plate 1 is fixed on the second bracket 31. When the servo motor 42 drives the coupling 43 to rotate, it drives the lead screw 73 and the lead screw nut 72 to move. The lead screw nut 72 then drives the first bracket 71 and the slider 23 to move. The slider 23 is slidably connected to the linear guide rail 22, and the slider 23 moves along the linear guide rail 22, thereby realizing the movement of the movable plate 1 along the linear guide rail 22. Under the linkage of the drive component 4, the moving component 7, and the sliding component 2, the movable plate 1 is moved along the linear guide rail 22. The other end of the movable plate 1 moves along the moving direction of the movable plate 1 under the action of the guide component 3, thereby realizing the overall movement of the movable plate 1.

[0044] Figure 4 The diagram shown is a schematic representation of the connection between the guide rail groove and the bearing of the adjustment device provided in one embodiment of this application; as shown Figure 4As shown, the guide assembly 3 also includes a guide groove 321, which is formed on the guide rail 32. The bearing 33 is installed in the guide groove 321, and the guide groove 321 is formed along the direction of extension of the guide rail 32. Specifically, under the linkage of the drive assembly 4, the moving assembly 7, and the sliding assembly 2, one end of the movable plate 1 moves along the linear guide rail 22, thereby driving the movable plate 1 to move along the linear guide rail 22, and at the same time driving the bearing 33 to move within the guide groove 321, thereby realizing the positional movement of the movable plate 1.

[0045] In one possible implementation, the guide assembly 3 further includes at least one bearing hole 311, which is formed on the second bracket 31. One end of the bearing 33 is fixedly connected in the bearing hole 311, and the other end of the bearing 33 is installed in the guide rail groove 321.

[0046] It should be understood that at least one bearing hole 311 is provided on the second bracket 31. The specific number of bearing holes 311 is not limited in this application, as long as the bearing 33 can move in the guide rail groove 321, thereby driving the second bracket 31 to move, and then driving the movable plate 1 to move.

[0047] In one possible implementation, the adjustment device further includes a mop 5 and a mop support frame 6. One end of the mop 5 is fixedly connected to the movable plate 1, and the other end of the mop 5 is mounted on the mop support frame 6. When the drive assembly 4 drives the movable plate 1 to move along the linear guide rail 22 and the guide rail groove 321, the mop 5 moves in the direction of movement of the movable plate 1 because it is fixedly connected to the movable plate 1. When the paper to be die-cut is small, it is necessary to adjust the gap between the die-cutting structure and the waste removal structure or between the waste removal structure and the finished product removal structure. At this time, the drive assembly 4 drives the movable plate 1 to move closer to the waste removal structure. As the paper moves, the width of the mop 5 increases, thus filling the gap between the die-cutting structure and the waste removal structure, or between the waste removal structure and the finished product removal structure. When the paper to be die-cut is large, the width of the mop 5 needs to be reduced. At this time, the drive component 4 drives the movable plate 1 to move away from the waste removal structure. Through the combined action of the drive component 4, the moving component 7, the sliding component 2, and the guide component 3, the relative position of the drive movable plate 1 and the mop 5 can be moved, which can realize the automatic adjustment of the width of the mop 5 without the need for manual adjustment, saving manpower and improving production efficiency.

[0048] In one possible implementation, the adjustment device further includes a photoelectric sensor 8, mounted on the first bracket 21, for detecting whether the movable plate 1 has moved to a designated position. Preferably, the photoelectric sensor 8 can be a laser photoelectric sensor, the laser emission direction of which is parallel to the direction in which the movable plate 1 extends toward the guide assembly 3.

[0049] Specifically, the servo motor 42, mounted on the motor bracket 41, rotates, driving the trapezoidal lead screw 72 via the coupling 43, and causing the lead screw nut 71 to move in direction B. Figure 2 This achieves the effect of moving the movable plate 1 along direction B. When the photoelectric sensor 8 detects an object 5mm away from the front end of the movable plate 1 (the end furthest from the mop 5), the movable plate 1 decelerates during the movement and completes the positioning and protects the servo motor 42 through the torque detection function of the servo motor. When the movable plate 1 contacts the object, the servo motor 42 feedback torque increases, and the movable plate 1 stops moving. At this time, the movable plate 1 has completed the adjustment.

[0050] In one possible implementation, the adjusting device further includes at least one suction hole 11, which is formed on the movable plate 1. After die-cutting the printed material or other coiled blanks, the printed material needs to pass through the adjusting device before entering the waste removal structure to clean the material outside the shape or cut marks of the printed material or other coiled blanks. When passing through the movable plate 1 of the adjusting device, the printed material or other coiled blanks, especially for lightweight printed materials, will drift or shake due to the airflow in their area during the conveying process. This prevents the printed material from smoothly entering the next process. Furthermore, since the die-cut printed material or other circular blanks are in a relatively loose state due to the presence of cut marks, it is necessary to open at least one air suction hole 11 on the movable plate 1 to prevent the printed material from breaking when it is floating or shaking. The movable plate 1 has a hollow cavity structure and is connected to an external air suction device, such as a blower. The blower draws in, compresses, and expels the gas in the hollow cavity of the movable plate 1, creating a low-pressure area in the area of ​​the movable plate 1, thereby causing the paper of the printed material to adhere to the surface of the movable plate 1.

[0051] Figure 5 The diagram shown is a structural schematic of a waste removal die-cutting machine provided in an embodiment of this application. Figure 5 As shown, the waste removal die-cutting machine 9 includes an adjustment device 911 for the aforementioned waste removal structure 91. During the die-cutting process, the printed material or other pre-cutting blanks are first passed through the die-cutting structure 92. Under pressure, the printed material or other pre-cutting blanks are cut into the required shape or cuts. Then, the printed material or other pre-cutting blanks of the required shape or cuts are moved to the waste removal structure 91 through the adjustment device 911. The die-cut material of the printed material or other pre-cutting blanks is collected in the waste removal structure 91. When smaller paper is used for production, smaller waste removal and finished product removal tools are also selected. This can lead to gaps between the waste removal structure and the die-cutting structure or between the waste removal structure and the finished product removal structure. The automatic adjustment of the width of the adjustment device 91 is used to fill these gaps between the die-cutting structure and the waste removal structure or between the waste removal structure and the finished product removal structure.
