Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf storage, in particular to a punching device. Background Art

[0002] Tobacco leaves are prone to infestation during storage, as tobacco moths can eat the leaves, causing serious economic losses. Therefore, pest control is crucial during tobacco storage. Taking into account environmental protection, pest control effectiveness, and pest control costs, nitrogen injection and oxygen reduction are commonly used methods for tobacco leaf pest control and daily maintenance. Specifically, tobacco leaves are placed in a confined space and filled with high-purity nitrogen. As the nitrogen concentration gradually increases, the oxygen concentration gradually decreases, ultimately creating a high-nitrogen, low-oxygen environment where tobacco moths suffocate and die from lack of oxygen.

[0003] However, most of the existing tobacco leaves are wrapped in an inner film and then placed in a tobacco box. Since the tobacco leaves are doubly sealed by the inner film and the tobacco box, it is difficult for nitrogen to quickly enter the tobacco leaves, resulting in the oxygen concentration in the tobacco leaves being unable to drop to a concentration that can suffocate tobacco insects in a short period of time. As a result, each insecticide operation consumes a lot of time, resulting in the tobacco leaves being unable to undergo subsequent processing for a long time, affecting the production efficiency of the tobacco leaves.

[0004] Therefore, a punching device is urgently needed to solve the above technical problems. Utility Model Content

[0032] like Figures 1 to 3As shown, this embodiment provides a punching device for punching holes in a cigarette box and the inner membrane of the tobacco covering within the box, allowing high-purity nitrogen to quickly enter and be distributed throughout the tobacco leaves, achieving rapid insecticide control. The punching device comprises a base plate 1, screws 2, and a hook assembly. Multiple screws 2 are provided, spaced apart on the base plate 1, allowing multiple through-holes to be formed simultaneously in the cigarette box and the inner membrane. The multiple through-holes are spaced apart, allowing high-purity nitrogen to quickly enter the tobacco leaves and be evenly distributed throughout the leaves, ensuring effective insecticide control. The multiple screws 2 are detachably connected to the base plate 1, facilitating regular replacement of the screws 2 and ensuring efficient punching. This also facilitates replacement of screws 2 of varying lengths based on the thickness of the cigarette box, improving the design rationality of the punching device. The hook assembly is connected to the base plate 1 and is used to connect to an external mobile device. The hook assembly facilitates the external mobile device's transport of the punching device, allowing the punching device to remain stable near the tobacco leaves, achieving rapid punching of the tobacco leaves and the inner membrane. The punching device provided in this embodiment can form multiple evenly distributed through holes on the cigarette box and the inner membrane at one time, which can improve the efficiency of insecticide. The design is reasonable and can adapt to cigarette boxes of different thicknesses.

[0033] In this embodiment, the base plate 1 can be made of a stainless steel plate. Stainless steel has a certain hardness, which can prevent the punching device from being deformed during the insertion into the cigarette box, thereby ensuring the stability of the overall structure of the punching device.

[0034] In this embodiment, the external mobile device can be a mechanical arm or a mobile robot.

[0035] In this embodiment, the substrate 1 is provided with a plurality of through holes 11, which are arranged in a row to improve the rationality of the arrangement of the plurality of through holes 11. The plurality of through holes 11 are provided in a one-to-one correspondence with the plurality of screws 2, wherein the through holes 11 are provided with internal threads, and the screws 2 are provided with external threads. The substrate 1 and the screws 2 are threadedly connected to each other so that the screws 2 can be detachably connected to the substrate 1. In another embodiment, a magnet sheet can be optionally attached to the inner wall of the through hole 11, and the screw 2 can be inserted into the through hole 11. Based on the principle of magnetic attraction, the screw 2 can be detachably connected within the through hole 11.

[0036] In this embodiment, the through hole 11 includes a first through hole 111 and a second through hole 112, and the screw 2 includes a first screw 21 and a second screw 22. The first screw 21 is threadedly connected to the first through hole 111, and the second screw 22 is threadedly connected to the second through hole 112. The diameter of the first screw 21 is larger than the diameter of the second screw 22. By providing first and second screws 21 and 22 of different specifications, and correspondingly providing first and second through holes 111 and 112 of different specifications, the first screw 21 can be installed for large cigarette boxes, while the second screw 22 can be installed for small cigarette boxes. This prevents damage to the small cigarette box structure and affects subsequent use. Before drilling holes in cigarette boxes of different specifications, staff can choose to use the first screw 21 or the second screw 22 according to the specifications of the cigarette box, further improving the rationality of the drilling device design. The diameter of the first screw 21 is 10mm-12mm, and the diameter of the second screw 22 is 8mm-10mm. The specific specifications of the first screw 21 and the second screw 22 need to be determined according to the specifications of the cigarette box and are not specifically limited here.

[0037] In another embodiment, the through holes can be set to be through holes of the same specifications, with internal threads provided in the through holes. The screws include a first screw and a second screw, wherein the first screw includes a first threaded area and a first punching area, the first threaded area is threadedly connected to the internal threads of the through hole, and the diameter of the first punching area is 10mm-12mm. The second screw includes a second threaded area and a second punching area, the second threaded area is threadedly connected to the internal threads of the through hole, and the diameter of the second punching area is 8mm-10mm. In this way, only one specification of through hole needs to be set on the substrate to meet the punching work of cigarette boxes and inner membranes of different specifications, which makes it easier for workers to process the punching device and reduces the processing difficulty of the punching device.

[0038] Preferably, the first through holes 111 and the second through holes 112 are arranged in a row along the length of the substrate 1. For ease of distinction, the row containing the first through holes 111 is referred to as the first through hole row, and the row containing the second through holes 112 is referred to as the second through hole row. The first through hole rows and the second through hole rows are arranged alternately. This not only allows for spacing between the multiple first through holes 111 and the multiple second through holes 112, but also improves the rationality of the layout of the first through holes 111 and the second through holes 112.

[0039] In this embodiment, the hook assembly includes a hook 31 and a fixing part, and the fixing part is used to fix the hook 31 to the substrate 1. The fixing part can be a bolt, and the fixing part can also be made of strong glue to adhere the hook 31 to the substrate 1. There is no specific limitation on the form of the fixing part. Preferably, two hooks 31 are provided, and the two hooks 31 are fixed on the substrate 1 at intervals. The setting of the hook 31 not only facilitates the connection between the external mobile device and the punching device, and realizes stable transportation of the punching device, but also facilitates the hanging of the punching device after the punching device completes the punching work, which is convenient for the storage of the punching device. The two hooks 31 are arranged at intervals to ensure that when the external mobile device transports the punching device, the punching device is more stably stressed and not easy to fall.

[0040] In this embodiment, the end of the screw 2 facing away from the substrate 1 has a tapered portion 23, that is, the end of the screw 2 inserted into the cigarette box has a tapered portion 23. In this way, when the screw 2 is inserted into the cigarette box, the tapered portion 23 can play a guiding role, so that the screw 2 can be inserted into the cigarette box and the inner membrane more smoothly to form a through hole.

[0041] As a preferred Figure 2 and Figure 4 As shown in FIG, the punching device further includes a protective cover 4 for selectively covering the plurality of screws 2. Since the screws 2 have tapered portions 23, workers are susceptible to being scratched by the tapered portions 23 during work. By providing the protective cover 4, workers can use the protective cover 4 to cover the plurality of screws 2 after completing the punching work in the cigarette box, thereby reducing the risk of being scratched by the tapered portions 23.

[0042] Regarding the installation of the protective cover 4, on the one hand, a folded edge facing the screw 2 can be optionally provided on each of the three sides of the base plate 1, namely the first folded edge 12, the second folded edge 13 and the third folded edge 14, wherein the first folded edge 12, the second folded edge 13 and the third folded edge 14 are arranged end to end, and an insert plate 41 is provided on both sides of the protective cover 4, and the insert plate 41 can be placed in the gap between the first folded edge 12, the second folded edge 13 and the third folded edge 14 and the base plate 1. The insert plate 41 includes a first insert plate and a second insert plate. In this embodiment, the first folded edge 12 is opposite to the third folded edge 14, the second folded edge 13 is located between the first folded edge 12 and the third folded edge 14, and the first insert plate and the second insert plate are away from each other. When installing the protective cover 4, the first insert plate and the second insert plate slide in along the first folded edge 12 and the third folded edge 14 respectively until the first insert plate and the second insert plate abut against the second folded edge 13, thereby completing the installation of the protective cover 4. Of course, on the other hand, it is also possible to choose not to set the first folded edge 12, the second folded edge 13 and the third folded edge 14 on the substrate 1, and directly connect the protective cover 4 to the substrate 1 through bolt fasteners, and install or remove the protective cover 4 by screwing the bolt fasteners in the forward or reverse direction, wherein the bolt fasteners can be bolts. There is no specific restriction on the installation of the protective cover 4.

[0043] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
