Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, specifically to an automatic punching device for composite paperboard. Background Technology

[0002] Paperboard can be categorized into packaging paperboard, decorative paperboard, industrial paperboard, and composite paperboard; according to its structure, it can be classified as single-layer or multi-layer paperboard; and according to its thickness, it can be classified as thin paperboard, medium-thickness paperboard, and thick paperboard. These classifications allow paperboard to adapt to different application scenarios, such as light packaging, medium-sized boxes, and heavy-duty crates.

[0003] Composite paperboard is a type of paperboard with a certain strength, made by bonding packaging paper together, and then processing, shaping, and cutting it. It features high strength and environmental friendliness, being composed of multiple materials, and possesses high strength and impact resistance, effectively protecting the packaged goods. Furthermore, composite paperboard does not contain harmful substances, can be recycled after reuse, and meets environmental protection requirements.

[0004] During the production and processing of composite paperboard, perforation is sometimes required depending on the usage needs. Traditionally, perforation of composite paperboard is mainly done manually. In actual operation, the position of the paperboard needs to be constantly adjusted to perforate it, which is very inconvenient, inefficient, and lacks precision, thus affecting the production quality of composite paperboard products.

[0011] Preferably, side guide grooves are provided on both inner walls of the upper frame, and guide slides are slidably connected in both side guide grooves. The other end of the two guide slides is fixedly connected to the side wall of the primary slide.

[0012] Preferably, a limit frame is fixedly installed on the upper surface of the workbench.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The automatic punching device for composite paperboard of this utility model can automatically complete the punching work of composite paperboard. During operation, only manual feeding and unloading of composite paperboard is required, and no manual punching is required. This can greatly improve the punching speed and efficiency of composite paperboard and make the operation more convenient.

[0015] Simultaneously, the punching head can move freely along the X, Y, and Z axes under the action of the threaded drive structure and the cylinder drive structure. This effectively improves the punching accuracy and makes the punching position more precise, thus improving the punching quality in the production of composite paperboard. Moreover, the X, Y, and Z axes are independent of each other, and can be operated simultaneously or independently in each axis. This makes the displacement of the punching head more precise and flexible, improving the overall performance. At the same time, the three-axis linkage can effectively increase the punching coverage area and avoid punching dead corners due to insufficient displacement. It has good practical performance and is suitable for widespread use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 an indirect connection through an intermediate medium; it can be a connection within 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.

[0024] Please see Figure 1-4An embodiment of this utility model is provided: an automatic punching device for composite cardboard, including a device cabinet 1, the upper surface of the device cabinet 1 is a workbench 2, and upper columns 3 are fixedly installed at the four corners of the upper surface of the workbench 2 by welding. The upper frame 4 is fixedly installed on the top support of the four upper columns 3. The upper frame 4 adopts a hollow structure design. A primary ball screw 5 is rotatably installed inside the upper frame 4 through bearings. A primary slide plate 6 is sleeved on the outside of the primary ball screw 5. The primary ball screw 5 and the primary slide plate 6 are threadedly connected.

[0025] Thus, when the first-stage ball screw 5 rotates, the first-stage sliding plate 6 connected to it by threads can move linearly left and right along the first-stage ball screw 5, which has a certain effect of changing the position of the drilling area and ensures the free movement of the drilling structure on the X-axis.

[0026] The left and right movement and movement distance of the first-stage slide plate 6 depend on the rotation direction and number of rotations of the first-stage ball screw 5.

[0027] A lower mounting plate 7 is fixedly installed on the lower surface of the first-stage slide plate 6. A connecting column 8 is fixedly installed on the lower surface of the bottom end of the lower mounting plate 7 by welding. The connecting column 8 is perpendicular to the first-stage ball screw 5. A linear groove is opened inside the connecting column 8. A second-stage ball screw 9 is rotatably installed inside the linear groove through a bearing. A second-stage threaded seat 12 is sleeved on the outer surface of the second-stage ball screw 9. The second-stage threaded seat 12 is threadedly connected to the second-stage ball screw 9.

[0028] This structure is the same as the X-axis movement method described above. When the secondary ball screw 9 rotates, the secondary threaded seat 12 connected to it can move back and forth along the secondary ball screw 9, ensuring the free movement of the punch head in the Y-axis.

[0029] In this embodiment, in order to drive the primary ball screw 5 and the secondary ball screw 9 to rotate, one end of the primary ball screw 5 is fixedly connected to the output shaft of the primary motor 10, and the primary motor 10 is fixedly installed on the side wall of the upper frame 4. One end of the secondary ball screw 9 is fixedly connected to the output shaft of the secondary motor 11, and the secondary motor 11 is fixedly installed on the outer wall of the end of the connecting column 8.

[0030] In order to improve the servo control accuracy of the thread transmission, both the primary motor 10 and the secondary motor 11 are servo motors. Thus, servo motors can be used for servo control during use, which can effectively improve the displacement accuracy during drilling.

[0031] In this embodiment, in order to ensure normal drilling process, a lower mounting bracket 13 is fixedly installed on the lower surface of the secondary thread seat 12, and a servo cylinder 14 is fixedly installed on the lower mounting bracket 13 by bolts.

[0032] The output end of the servo cylinder 14 is movably connected to a pneumatic rod, and a punching head 15 is fixedly installed at the bottom end of the pneumatic rod.

[0033] This structural design allows the pneumatic rod to extend and retract via a servo cylinder 14. When the pneumatic rod extends, it causes the punching head 15 at the bottom to descend, thereby punching holes in the composite cardboard below. This completes the automated punching process of this invention.

[0034] In this embodiment, in order to provide a certain displacement guidance for the left and right displacement of the first-stage slide plate 6, side guide grooves 16 are provided on both inner walls of the upper frame 4, and guide slide plates 17 are slidably connected in both side guide grooves 16. The other end of the two guide slide plates 17 is fixedly connected to the side wall of the first-stage slide plate 6.

[0035] In this way, the combined use of the guide slide plate 17 and the side guide groove 16 can provide a certain displacement guidance when the first-stage slide plate 6 moves, and has a good guide rail effect.

[0036] In this embodiment, in order to limit the left and right sides of the composite paperboard, a limiting frame 18 is fixedly installed on the upper surface of the workbench 2. With this structural design, the composite paperboard that is compatible with the processing size of this utility model can be placed into the limiting frame 18 during use. In this way, the limiting frame 18 can limit the perimeter of the composite paperboard, preventing the composite paperboard from moving during punching and improving the stability and accuracy of punching.

[0037] Working principle: When using this utility model, a composite cardboard that is compatible with the processing size of this utility model can be placed into the limiting frame 18. The limiting frame 18 can limit the composite cardboard around its perimeter, preventing it from moving during punching and improving the stability and accuracy of punching.

[0038] During punching, the servo cylinder 14 can drive the pneumatic rod to extend and retract. When the pneumatic rod extends, it will drive the punching head 15 at the bottom to descend. The descending punching head 15 can punch the composite cardboard below, thus completing the automated punching work of this utility model.

[0039] When the drilling position needs to be changed, the first-stage motor 10 can drive the higher-stage ball screw 5 to rotate. When the first-stage ball screw 5 is rotating, the first-stage sliding plate 6 connected to it can move linearly left and right along the first-stage ball screw 5. In this way, the left and right movement of the first-stage sliding plate 6 can drive the lower drilling head 15 to move left and right synchronously, thus achieving a certain drilling area position change effect and ensuring the free movement of the drilling head 15 on the X-axis.

[0040] The secondary motor 11 can drive the headphone ball screw 9 to rotate. When the secondary ball screw 9 rotates, the secondary threaded seat 12 connected to it can move back and forth along the secondary ball screw 9. In this way, the movement of the secondary threaded seat 12 can drive the punching head 15 below to move back and forth synchronously, thereby ensuring the free movement of the punching head 15 in the Y-axis.

[0041] With the combined use of the above structures, the automatic perforation device for composite paperboard of this utility model can automatically complete the automatic perforation of composite paperboard. During operation, only manual feeding and unloading of composite paperboard is required, and no manual perforation is required. This can greatly improve the perforation speed and efficiency of composite paperboard, and make operation more convenient.

[0042] Meanwhile, the punching head can move freely along the X, Y, and Z axes under the action of the threaded drive structure and the cylinder drive structure. This can effectively improve the punching accuracy and make the punching position more precise, thus improving the punching quality in the production of composite paperboard. Moreover, the X, Y, and Z axes are independent of each other, and can be operated simultaneously or independently in each axis. This makes the displacement effect of the punching head more precise and flexible, improves the overall use effect, has good performance, and is suitable for widespread use.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
