Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing and die-cutting technology, and in particular to a dual-channel gravure printing inline die-cutting device, a die-cutting workstation and a post-processing system. Background Technology
[0002] Cigarette packaging manufacturers typically use multi-color gravure printing machines to complete multi-color printing in one go. After printing, to improve the overall performance of the machine, the printing unit is equipped with two post-processing devices: in-line die-cutting and winding, also known as dual-channel. The die-cutting device directly processes the cigarette labels into finished products (single cigarette labels), while the winding device produces semi-finished paper rolls. These paper rolls facilitate subsequent post-processing steps such as hot stamping, coding, die-cutting, and inspection.
[0003] This type of machine is designed with two single-channel units: a die-cutting workstation and a paper-winding device equipped with a high-altitude paper guide frame. The die-cutting workstation is installed adjacent to the printing unit and has four die-mounting stations. A 3.2-ton hoist is installed above the die-cutting stations to lift the dies, and the printed paper enters the die-cutting workstation directly. The paper-winding device is installed at the rear of the die-cutting channel. Its ultra-high paper guide frame spans the 3.2-ton hoist frame, and the printed paper must pass through the high-altitude paper guide frame before entering the paper-winding device. The disadvantages of this design include poor stability of the high-altitude paper guide frame, long paper path resulting in significant waste, high clearance requirements in the workshop, difficulty in paper threading, and inconvenient operation. The ultra-high paper guide frame also increases equipment manufacturing, installation, and maintenance costs. Utility Model Content
[0004] This utility model provides a dual-channel gravure printing line die-cutting device, a die-cutting workstation, and a post-processing system. Its purpose is to reduce the height of the paper guide steel frame, thereby reducing the net height of the workshop space.
[0005] To achieve the above objectives, this utility model provides a dual-channel gravure printing inline die-cutting device, comprising:
[0006] The die-cutting roller assembly includes a first die-cutting roller and a second die-cutting roller. The rotation axes of the first die-cutting roller and the second die-cutting roller are arranged parallel to each other. The rotation directions of the first die-cutting roller and the second die-cutting roller are opposite. A die-cutting gap exists between the first die-cutting roller and the second die-cutting roller.
[0007] A paper guide assembly is disposed above the die-cutting roller group, and a conveying gap is formed between the paper guide assembly and the die-cutting roller group. The conveying gap is configured to convey paper so that the paper can be conveyed within the die-cutting device.
[0008] When the paper enters the die-cutting gap, it can be die-cut. When the paper enters the conveying gap, it can be conveyed to the paper guide frame that is matched with the die-cutting device, so as to reduce the height of the paper guide frame.
[0009] In one embodiment, the conveying gap includes a turning gap and a transport gap. The paper guiding assembly includes a paper guide frame and a paper guide roller. The paper guide roller is arranged at intervals with the die-cutting roller group. The turning gap is formed between the paper guide roller and the die-cutting roller group. The paper guide frame is disposed above the die-cutting roller group. The paper guide roller is rotatably connected to the paper guide frame. The transport gap is formed between the paper guide roller and the paper guide frame. The transport gap is located above the turning gap. There are multiple die-cutting devices. The multiple die-cutting devices are arranged along the paper conveying direction. Along the paper conveying direction, when the paper passes through the first die-cutting device, the paper enters the transport gap. When the paper passes through the last die-cutting device, the paper enters the turning gap.
[0010] The second aspect of this utility model provides a dual-channel gravure printing inline die-cutting workstation, comprising:
[0011] The die-cutting apparatus described in any of the foregoing embodiments;
[0012] The frame includes a base and a hanger, the base and the hanger enclosing an installation space for mounting the die-cutting device;
[0013] When the paper enters the die-cutting gap, the paper can be die-cut. When the paper enters the conveying gap, the paper can be conveyed to the paper guide frame so that the height of the paper guide frame is lower than the height of the hanger.
[0014] In one embodiment, the frame has a die-cutting feed channel and a rewinding feed channel. The die-cutting feed channel is connected to the die-cutting gap, and the rewinding feed channel is connected to the conveying gap. The die-cutting workstation further includes a switching assembly located upstream of the die-cutting device along the paper conveying direction. The switching assembly includes a switching frame, a first switching roller, and a second switching roller. The switching frame is disposed on one side of the hanger. The first switching roller and the second switching roller are rotatably connected to the switching frame. The second switching roller is disposed above the first switching roller. When the paper passes the first switching roller, the paper enters the die-cutting gap through the die-cutting feed channel, or the paper enters the conveying gap through the rewinding feed channel via the second switching roller.
[0015] The third aspect of this utility model provides a dual-channel gravure printing inline post-processing system, comprising:
[0016] The die-cutting workstation described in any of the foregoing embodiments;
[0017] A paper guide steel frame has a paper guide channel, which is connected to the conveying gap;
[0018] A paper winding device is connected to the paper guide frame, through which the paper enters the paper winding device for winding.
[0019] The above-mentioned solution of this utility model has the following beneficial effects:
[0020] In this embodiment, the paper guide assembly is positioned above the die-cutting roller assembly. This assembly guides the paper forward, enabling the die-cutting device to not only die-cut the paper but also guide it. Paper destined for the roll-up device is first transported within the die-cutting device and then by the paper guide frame to the roll-up device for winding. This eliminates the need for the paper guide frame to cross the frame used to mount the die-cutting device, significantly improving the adjustability of its placement. For example, the height of the paper guide frame can be lowered to be as close as possible to the conveyor gap, allowing the paper to be transported smoothly through the frame to the roll-up device for winding. The lower height of the paper guide frame reduces the height requirements of the corresponding workshop, allowing workshops with lower clearance to perform die-cutting and winding of paper, and also improving the stability of the paper guide frame. Furthermore, the shorter height of the paper guide frame shortens the paper transport path, reducing paper consumption, increasing output, and improving the stability of paper tension.
[0021] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0030] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] For related technologies, please refer to Figure 4 , Figure 5 and Figure 6After the paper 400 is printed and output in the printing unit, it can directly enter the die-cutting gap 11a for die-cutting, for example, into multiple cigarette packs. Alternatively, it can enter the paper winding device 300 through the paper guide channel 200a of the paper guide frame 200 to be rewound into a paper roll. However, there is no paper guide assembly 12 above the die-cutting roller group 11, which means that the existing die-cutting device does not have a paper guiding function. This means that the paper guide frame 200 can only be set above the frame 2 so that it can cross the frame 2, allowing the paper 400 to smoothly enter the paper winding device 300 through the paper guide channel 200a. This results in a relatively high height for the paper guide frame 200, leading to a series of problems such as poor stability of the paper guide frame 200, a long paper guide channel 200a resulting in significant paper waste, a higher required workshop clearance height, greater difficulty in paper feeding, and inconvenient operation. In addition, the height of the paper guide steel frame 200 increases the manufacturing, installation and maintenance costs of the entire post-processing system, which is not conducive to actual production.
[0034] In view of this, this application proposes a dual-channel gravure printing inline die-cutting device 1, which can not only die-cut the paper 400, but also guide the paper, so that the paper guide frame 200 can transfer the paper 400 to the paper winding device 300 without crossing the frame 2, thereby reducing the height of the paper guide frame 200.
[0035] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The die-cutting device 1 includes a die-cutting roller group 11 and a paper guide assembly 12.
[0036] The die-cutting roller assembly 11 includes a first die-cutting roller 111 and a second die-cutting roller 112. The rotation axis of the first die-cutting roller 111 and the rotation axis of the second die-cutting roller 112 are arranged parallel to each other. The rotation direction of the first die-cutting roller 111 is opposite to that of the second die-cutting roller 112. A die-cutting gap 11a is provided between the first die-cutting roller 111 and the second die-cutting roller 112. For example, see [reference needed]. Figure 1 The first die-cutting roller 111 and the second die-cutting roller 112 are both rotatably connected to the die-cutting frame. The first die-cutting roller 111 and the second die-cutting roller 112 can rotate in opposite directions under the drive of an external drive device. The outer peripheral surface of the first die-cutting roller 111 has die-cutting prints, and the outer peripheral surface of the second die-cutting roller 112 is a relatively smooth curved surface, so that when the paper 400 enters the die-cutting gap 11a, the paper 400 can be die-cut into multiple cigarette packs.
[0037] The paper guiding component 12 is arranged above the die-cutting roller set 11. A conveying gap 12a is formed between the paper guiding component 12 and the die-cutting roller set 11. The conveying gap 12a is configured to convey the paper 400 so that the paper 400 can be conveyed within the die-cutting device 1. The paper guiding component 12 includes a paper guiding roller 121. The paper guiding roller 121 is arranged at an interval from the die-cutting roller set 11. For example, the rotation axis of the paper guiding roller 121 is arranged parallel to the rotation axis of the first die-cutting roller 111 or the second die-cutting roller 112, so as to form a turning gap 121a between the paper guiding roller 121 and the die-cutting roller set 11.
[0038] Please refer to Figure 1 and Figure 3 , when the paper 400 enters the die-cutting gap 11a, the paper 400 can be die-cut. When the paper 400 enters the conveying gap 12a, the paper 400 can be conveyed onto the paper guiding steel frame 200 supporting the die-cutting device 1 to reduce the height of the paper guiding steel frame 200. It should be noted that whether the paper 400 enters the die-cutting gap 11a or the conveying gap 12a can be manually guided to switch the paper 400. When the paper 400 is manually guided into the conveying gap 12a and then manually guided onto the paper guiding steel frame 200.
[0039] In the embodiment of the present application, the paper guiding component 12 is arranged above the die-cutting roller set 11, and the paper guiding component 12 can guide the paper 400 to advance, so that the die-cutting device 1 can not only die-cut the paper 400, but also has the function of guiding the paper. The paper 400 that needs to enter the paper winding device 300 can be first transmitted within the die-cutting device 1 and then transmitted by the paper guiding steel frame 200 into the paper winding device 300 for winding, so that the paper guiding steel frame 200 does not need to span the frame 2 for installing the die-cutting device 1, and thus the adjustability of the layout position of the paper guiding steel frame 200 is greatly improved. For example, the height of the paper guiding steel frame 200 can be reduced as much as possible to be close to the conveying gap 12a, so that the paper 400 can be smoothly transmitted by the paper guiding steel frame 200 into the paper winding device 300 for winding. The low height of the paper guiding steel frame 200 can reduce the height requirement of the corresponding workshop, enabling the workshop with a low clear height to perform die-cutting and winding of the paper 400, and also improving the stability of the paper guiding steel frame 200. Moreover, the paper guiding steel frame 200 with a low height shortens the transmission path of the paper 400, which is beneficial to reducing the consumption of the paper 400, improving the output rate, and also improving the stability of the tension of the paper 400.
[0040] In one embodiment, please refer to Figure 1 and Figure 2The conveying gap 12a includes a deflection gap 121a and a transport gap 121b. The paper guide assembly 12 includes a paper guide frame 122 and a paper guide roller 121. The paper guide roller 121 is arranged at intervals from the die-cutting roller group 11. For example, the rotation axis of the paper guide roller 121 is arranged parallel to the rotation axis of the first die-cutting roller 111 or the second die-cutting roller 112, so that a deflection gap 121a is formed between the paper guide roller 121 and the die-cutting roller group 11. The paper guide frame 122 is disposed above the die-cutting roller group 11. For example, the paper guide frame 122 can be connected to the die-cutting frame. The paper guide roller 121 and the paper guide frame 122 are rotatably connected. A transport gap 121b is formed between the paper guide roller 121 and the paper guide frame 122. The transport gap 121b is located above the deflection gap 121a and the two are relatively close. There are multiple die-cutting devices 1, and the multiple die-cutting devices 1 are arranged along the transport direction of the paper 400. Along the transport direction of the paper 400, when the paper 400 passes the first die-cutting device 1, the paper 400 enters the transport gap 121b, so that the paper 400 can be transported within multiple die-cutting devices 1. The guide roller 121 can support the paper 400 to facilitate its transport. When the paper 400 passes the last die-cutting device 1, the paper 400 enters the turning gap 121a, for example, as... Figure 1 , Figure 2 and Figure 3 The paper 400 shown bends upward after passing through the turning gap 121a and then enters the paper guide frame 200 to be transferred to the paper winding device 300.
[0041] Please see Figure 2 The second aspect of this application provides a dual-channel gravure printing inline die-cutting workstation 100, including the die-cutting device 1 and frame 2 in the aforementioned embodiments.
[0042] The frame 2 includes a base 21 and a hanger 22. The base 21 and the hanger 22 enclose an installation space 2a for mounting the die-cutting device 1. For example, the base 21 is used to provide a die-cutting station for placing multiple die-cutting devices 1, and the hanger 22 is used to suspend the die-cutting devices 1.
[0043] When the paper 400 enters the die-cutting gap 11a, the paper 400 can be die-cut. When the paper 400 enters the conveying gap 12a, the paper 400 can be conveyed to the paper guide frame 200 so that the height of the paper guide frame 200 can be lower than the height of the hanger 22.
[0044] In one embodiment, please refer to Figure 2The frame 2 has a die-cutting feed channel 2b and a rewind feed channel 2c, with the die-cutting feed channel 2b communicating with the die-cutting gap 11a. For example, after the paper 400 is output from the printing unit, it enters the die-cutting gap 11a through the die-cutting feed channel 2b. The rewind feed channel 2c communicates with the transport gap 12a. For example, after the paper 400 is output from the printing unit, it enters the turning gap 121a through the rewind feed channel 2c. For example, when there are multiple die-cutting devices 1, the paper 400 first enters the transport gap 121b through the rewind feed channel 2c, and then enters the turning gap 121a. The die-cutting workstation 100 also includes a switching assembly 3, which is located upstream of the die-cutting device 1 along the transport direction of the paper 400. For example, the switching assembly 3 is located between the printing unit (not shown) and the frame 2. The switching assembly 3 includes a switching frame 31, a first switching roller 32, and a second switching roller 33. The switching frame 31 is disposed on one side of the hanger 22. Both the first switching roller 32 and the second switching roller 33 are rotatably connected to the switching frame 31. The second switching roller 33 is positioned above the first switching roller 32. When the paper 400 passes through the first switching roller 32, the paper 400 enters the die-cutting gap 11a through the die-cutting feed channel 2b, or the paper 400 enters the conveying gap 12a through the winding feed channel 2c via the second switching roller 33, so that the paper 400 can be switched to different channels according to actual needs, and then be die-cut or wound up.
[0045] Please see Figure 3 The third aspect of this application proposes a dual-channel gravure printing inline post-processing system, including the die-cutting workstation 100, paper guide frame 200, and paper winding device 300 as described in the preceding embodiments. The paper guide frame 200 has a paper guide channel 200a. The paper guide channel 200a communicates with a conveying gap 12a, allowing paper 400 to enter the paper guide channel 200a after being output through a turning gap 121a. The paper winding device 300 is connected to the paper guide frame 200, and the paper 400 enters the paper winding device 300 through the paper guide frame 200 for winding. The post-processing system of this application can reduce the height of the paper guide frame 200.
[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
