Description

Technical Field

[0001] This utility model belongs to the field of die-cutting machine technology, and in particular relates to a corrugated paper die-cutting device. Background Technology

[0002] A corrugated paper die-cutting device is a device for die-cutting corrugated paper. It generally includes a die-cutting base plate. During die-cutting, the corrugated paper is placed on the die-cutting base plate. During die-cutting, a large amount of waste is generated on the surface of the die-cutting base plate. During the die-cutting process, the accumulation of waste will affect the subsequent cutting of corrugated paper. Therefore, the waste on the surface of the die-cutting base plate needs to be cleaned after each die-cutting.

[0003] Currently, cleaning is mostly done manually. Some corrugated paper die-cutting devices are equipped with units for cleaning debris and dust. However, nowadays, the cleaning unit is mostly linked to the sliding table of the die-cutting blade. The cleaning unit uses a negative pressure suction head to suck up debris. During die-cutting, the negative pressure suction head is not working. After die-cutting, the die-cutting blade is moved to move the negative pressure head. At this time, the vacuum cleaner connected to the negative pressure suction head is turned on to suck up and clean the micro-dust on the surface of the die-cutting base plate.

[0004] The aforementioned cleaning unit and die-cutting blade are linked, so the die-cutting blade and cleaning unit need to move together during cleaning or cutting. This will affect both individual cleaning and cutting operations. Furthermore, the cleaning method using only a negative pressure suction head is not suitable for cleaning large-sized debris. Therefore, there is still room for improvement in the existing die-cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a corrugated paper die-cutting device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a corrugated paper die-cutting device, including a die-cutting base plate, and further including: a cleaning unit, the cleaning unit including:

[0008] The first horizontal beam is connected to the top of the two vertical beams at both ends. Two guide rods are vertically guided on the first vertical beam, and a connecting plate is provided at the lower end of the two guide rods.

[0009] The second horizontal beam is connected at both ends to the upper ends of the two first vertical beams;

[0014] Furthermore, the drive unit includes two connecting rod assemblies disposed between the first crossbeam and the second crossbeam, and a single-acting cylinder connected at both ends to the two connecting rod assemblies.

[0015] Furthermore, the connecting rod assembly includes a first rod and a second rod of equal length, and a connector is provided at the end of the single-acting cylinder. One end of the first rod and the second rod are hinged to the connector, and the other end is hinged to the first crossbeam and the second crossbeam, respectively.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Example 1

[0033] Please refer to Figure 1 As one specific implementation, this utility model includes a corrugated paper die-cutting device, which includes a die-cutting base plate 1 and a cleaning unit, the cleaning unit including:

[0034] The sliding seat includes two vertical beams 22 that are guided and slidably disposed on both sides of the die-cutting base plate 1;

[0035] The first horizontal beam 23 is connected to the top of the two vertical beams 22 at both ends. Two guide rods 25 are vertically guided on the first vertical beam 22, and a connecting plate 250 is provided at the lower end of the two guide rods 25.

[0036] The second horizontal beam 26 is connected at both ends to the upper ends of the two first vertical beams 22;

[0037] A drive unit is disposed between the first crossbeam 23 and the second crossbeam 26, and is used to drive the second crossbeam 26 to move in the vertical direction;

[0038] The two opposite surfaces of the connecting plate 250 are respectively provided with scraper 24 and vacuum negative pressure suction head 28.

[0039] For details, please refer to Figures 1-6 The die-cutting base has sliding seats on both sides, each sliding seat including a vertically arranged vertical beam 22. A first horizontal beam 23 is connected to the top of the vertical beam 22. Two guide cylinders 230 are symmetrically arranged on the first horizontal beam 23 about the middle of it. A guide rod 25 guides the guide cylinders 230. A second horizontal beam 26 is connected to the upper end of the guide rod 25, and a connecting plate 250 is connected to the lower end of the guide rod 25. The connecting plate 250 is detachably and fixedly connected to the lower end of the guide rod 25. A scraper 24 and a vacuum suction head 28 are respectively provided on the opposite sides of the connecting plate 250. (Reference) Figure 7 , Figure 8 The connecting plate 250 has multiple through holes 2501 evenly spaced. The vacuum suction head 28 is integrally welded with a lap plate 282. The vacuum suction head 28 is connected to a connector 280 for connection to a vacuum cleaner. The lower end of the vacuum suction head 28 has an suction port 281. The scraper 24 has multiple strip holes 240 corresponding one-to-one with the through holes 2501 on the lap plate 282. The lap plate 282 also has second strip holes 240 corresponding one-to-one with the through holes 2501. A screw passes through the second strip holes 240, the through holes 2501, and the strip holes 240, and is then threaded with a nut, thus fixing the scraper 24 and the vacuum suction head 28. (See reference) Figure 7After fixing the scraper 24 and the vacuum suction head 28, the lower end of the scraper 24 is below the suction port 281, and the vertical distance between them is between 0.5 cm and 2 cm. A drive unit is provided between the first crossbeam 23 and the second crossbeam 26, which can drive the second crossbeam 26 in the vertical direction. When the cleaning unit is not working, the drive unit is in the initial state. At this time, the lowermost end of the scraper 24 is spaced apart from the die-cutting base plate 1, thereby reducing the obstruction of the scraper 24 to the corrugated paper during die-cutting. This makes the work more convenient. When cleaning is needed, the drive unit is in working condition. At this time, the guide rod 25 moves downward, so that the scraper 24 contacts the upper surface of the die-cutting base plate 1. At this time, the vacuum cleaner connected to the vacuum negative pressure suction head 28 is turned on, and the sliding seat is pushed from one end of the die-cutting base plate 1 to the other end to clean the die-cutting base plate 1. After moving to the other end, the drive unit is controlled to the initial state, so that the scraper 24 is separated from the die-cutting base plate 1. The vacuum cleaner is turned off, and the sliding seat is pushed back to the other end of the die-cutting base plate 1, thus completing the cleaning.

[0040] It should be noted that the drive unit can be either an electric telescopic rod or a pneumatic telescopic rod. One end is connected to the second crossbeam 26 and the other end is connected to the first crossbeam 23 to achieve operation. The control methods of the electric telescopic rod and the pneumatic telescopic rod are conventional technical means in this field. This application adopts the existing technology and will not elaborate on them one by one.

[0041] Furthermore, as a specific implementation, for ease of assembly and subsequent maintenance, the first crossbeam 23 and the vertical beam 22 are detachably and fixedly connected. Specifically, a flange plate is provided at the top of the vertical beam 22, and flange plates are adapted to be provided at both ends of the first crossbeam 23. The flange plates are fixed by screws, thereby achieving a detachable and fixed connection.

[0042] Furthermore, as a specific implementation method, refer to Figure 1 The die-cutting base plate 1 has guide members 20 on both sides, and a sliding member 210 is slidably mounted on the guide member 20. The sliding member 210 is detachably and fixedly connected to a sliding plate 21, and the vertical beam 22 is connected to the sliding plate 21. Specifically, a base is provided below the die-cutting base plate 1, and guide members 20 are horizontally mounted on both sides of the base. The sliding member 210 is mounted on the guide member 20, and the sliding member 210 is detachably and fixedly connected to the sliding plate 21. The sliding plate 21 is welded to the vertical beam 22, which facilitates assembly.

[0043] Example 2

[0044] As one specific implementation method, refer to Figures 2-10This application provides a corrugated paper die-cutting device, which differs from Embodiment 1 in that the driving unit includes two connecting rod assemblies 27a disposed between the first crossbeam 23 and the second crossbeam 26, and a single-acting cylinder 27 connected at both ends to the two connecting rod assemblies 27a.

[0045] Specifically, two sets of connecting rod assemblies 27a are provided between the first crossbeam 23 and the second crossbeam 26, and a single-acting cylinder 27 is provided between the two sets of connecting rod assemblies 27a. With this arrangement, the two connecting rod assemblies 27a can be driven by one cylinder, and the two connecting rod assemblies 27a can drive the second crossbeam 26 at two points. The two-point drive can ensure the balance of the drive, and the single-acting cylinder 27 can ensure the synchronization of the two-point drive.

[0046] Furthermore, as a specific implementation method, refer to Figures 2-6 The connecting rod assembly 27a includes a first rod 27a-1 and a second rod 27a-2 of equal length. A connector 270 is provided at the end of the single-acting cylinder 27. One end of the first rod 27a-1 and the second rod 27a-2 are hinged to the connector 270, and the other end is hinged to the first crossbeam 23 and the second crossbeam 26, respectively.

[0047] Specifically, the first crossbeam 23 is provided with two first ear plates 231 corresponding to the two connecting rod assemblies 27a, and the second crossbeam 26 is provided with two second ear plates 261. Both ends of the single-acting cylinder 27 are threadedly connected to connecting pieces 270. The first rod 27a-1 is hinged to the second ear plate 261, the second rod 27a-2 is hinged to the first ear plate 231, and the connecting pieces 270 are hinged to both the first rod 27a-1 and the second rod 27a-2. (Reference) Figure 2 When the connecting rod assembly 27a is in the state shown in the figure, the lower end of the scraper 24 is in contact with the die-cutting platform. At this time, the single-acting cylinder 27 is in the working state. In the initial state, refer to Figure 10 When the single-acting cylinder 27 depresses, it extends under the rebound force of its internal elastic element. This extension, via the connecting rod assembly 27a, pushes the second crossbeam 26 upward, thereby separating the scraper 24 from the die-cutting platform. It should be noted that the single-acting cylinder 27... Figure 10The specific structure shown is a conventional structure in the art, and the control method is also a conventional technology in the art. Specifically, it includes a cylinder 272, a piston 273, a compression spring 276, and a piston rod 275. A connecting post 2720 is integrally welded to the end of the cylinder 272. The ends of the connecting post 2720 and the piston rod 275 are both threadedly connected to connecting parts 270. The air inlet 274 is connected to the air source. The compression spring 276 provides the piston 273 with the elastic force to return and extend. During operation, the air source supplies compressed gas to the cylinder, pushing the piston 273 to squeeze the compression spring 276 and move it. The single-acting cylinder 27 contracts, thereby driving the connecting rod assembly 27a to move the second crossbeam 26 downward. When the single-acting cylinder 27 needs to extend, the air source stops supplying gas and the gas inside the cylinder is released. At this time, under the elastic force of the compression spring 276, the piston 273 is pushed to return and extend. The above working method is a conventional driving method of the single-acting cylinder 27 in the art, using existing technology, which should be understood by those skilled in the art.

[0048] Furthermore, as a preferred embodiment, refer to Figure 9 The upper end of the guide rod 25 is connected to a horizontal rigid arm 251. The two ends of the second crossbeam 26 have upward-facing overlapping surfaces 263, and the rigid arm 251 engages with the overlapping surfaces 263. Specifically, through this overlapping engagement, when the drive unit drives the second crossbeam 26 upward, the overlapping surfaces 263 apply force to the rigid arm 251, thereby driving the guide rod 25 upward. When the second crossbeam 26 is driven downward, the overlapping surfaces 263 do not apply force to the rigid arm 251. At this time, the scraper 24, the vacuum suction head 28, and the guide rod 25 move downward under their own gravity, causing the scraper 24 to contact the die-cutting base plate 1. Relying on the rigidity of the scraper 24 itself, this method, relying on its own gravity, can avoid excessive contact force between the scraper 24 and the die-cutting base plate 1, reducing wear.

[0049] Furthermore, as a preferred embodiment, refer to Figure 9 Along the sliding direction of the sliding seat, vertical plates 262 are provided on both sides of the overlapping surface 263; the end of the rigid arm 251 is provided with an overlapping member 252 that can be inserted between the two vertical plates 262, and the side of the overlapping member 252 is guided and slidably engaged with the vertical plate 262. Specifically, by setting the vertical plate 262 and the overlapping member 252 to guide and engage, the rigid arm 251 and the second crossbeam 26 can be prevented from shifting, ensuring the effective engagement of the overlapping member 252 and the overlapping surface 263.

[0050] Furthermore, as a specific implementation method, refer to Figure 9 It also includes a limiting plate 264 disposed at the upper end of the two vertical plates 262. By setting the limiting plate 264, the integrity of the two vertical plates 262 can be improved and the guiding effect can be enhanced.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
