Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a reusable box for raw tobacco leaves that is easy to package. Background Technology

[0002] Raw tobacco leaf recycling containers are specialized containers widely used in the logistics and warehousing processes of the tobacco industry. Their use is mainly based on multiple needs, such as protecting the characteristics of tobacco leaves, improving logistics efficiency, controlling costs, and complying with industry standards.

[0003] Currently, commercially available tobacco leaf recycling boxes excel in ease of sealing, primarily using Velcro as the sealing method. Velcro offers convenience in sealing and retrieving tobacco leaves due to its simple operation and quick opening and closing. However, this design has gradually revealed some drawbacks in long-term practical use.

[0004] Because hook and loop fasteners are directly attached to the surface of the turnover box, the adhesive layer at the edges of the fasteners gradually weakens after repeated stress during frequent loading, unloading, handling, and storage operations. This makes it difficult for the corners to adhere tightly to the box surface, allowing them to be easily pulled off. The sealing performance and securing effect of the hook and loop fasteners are significantly reduced, weakening their protective function for the raw tobacco leaves inside the box and limiting the reliability and durability of the turnover box under long-term, high-intensity use. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a raw tobacco leaf recycling box that is easy to package.

[0006] The technical implementation scheme of this utility model is as follows: a reusable box for raw tobacco leaves that is easy to package includes a body, a cover plate, a folding plate and a fixing component. The cover plate is fixedly connected to the front and rear sides of the top and bottom of the body, and the folding plate is fixedly connected to the left and right sides of the top and bottom of the body. Two gripping holes are opened at intervals on the front and rear sides of the body, and one gripping hole is also opened on the left and right sides of the body. The fixing component is provided on the folding plate and the cover plate, and the fixing component is used to fix adjacent cover plates and folding plates.

[0007] More preferably, the fixing component includes hook and loop fasteners, a fixing frame, and limiting posts. A pair of hook and loop fasteners are symmetrically fixed to the outer side wall of the folding plate, and four hook and loop fasteners are fixed to the inner side wall of the cover plate at intervals. The hook and loop fasteners on the folding plate are rough-surfaced, while the hook and loop fasteners on the cover plate are hook-surfaced. A fixing frame is fixed to the folding plate and the cover plate near the hook and loop fasteners. Multiple limiting posts are fixed to the side of the fixing frame near the adjacent hook and loop fasteners at intervals along the circumference. Multiple limiting holes are opened on the hook and loop fasteners along the circumference corresponding to the adjacent limiting posts.

[0008] More preferably, the body, cover plate, and folding plate are all made of PP plastic hollow board.

[0009] More preferably, it also includes a fixing block, a mounting rod, an L-shaped outer shell, an L-shaped colored plate, a screw, and a hand-tightening nut. The left side panel and the rear side panel of the main body are fixedly connected to the fixing block on their respective sides. The fixing block is fixedly connected to the mounting rod. The L-shaped outer shell is slidably mounted on the two mounting rods. The L-shaped colored plate is slidably connected to the side of the L-shaped outer shell that is close to the main body. The upper and lower sides of the L-shaped outer shell are rotatably connected to the screw. The screw passes through the L-shaped colored plate and is threaded to it. The upper end of the screw is fixedly connected to the hand-tightening nut. The left side panel and the rear side panel of the main body are both provided with square openings on their respective sides.

[0010] More preferably, the mounting rod and the L-shaped housing are interference fit.

[0011] More preferably, it also includes a transparent plate, with the transparent plate fixedly connected to each of the two square openings on the main body.

[0012] This utility model has the following advantages: 1. By sealing the top and bottom of the turnover box body with Velcro, the operation is simple and quick, and the sealing can be completed quickly, effectively reducing the burden on the staff. At the same time, when the turnover box is reused, the fixing frame and limiting post can limit and fix the corners of the Velcro, preventing it from being pulled up or curling up, avoiding the decrease in sealing performance and fixing effect due to weakened adhesion, ensuring the stable use of Velcro for a long time, and improving the reliability and durability of the turnover box.

[0013] 2. When the L-shaped outer shell is not initially installed, the main body can be folded for storage, which greatly saves storage space. When in use, the L-shaped outer shell is installed, and the height of the L-shaped colored plate is adjusted by turning the hand-tightening nut, so that the square opening presents different colors, providing a clear identification mark for the external identification system, which facilitates quick and accurate identification of turnover boxes, efficiently records their relevant information, and improves the efficiency and convenience of turnover box management.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example: A reusable box for easy packaging of raw tobacco leaves, such as... Figures 1-5 As shown, the device includes a body 1, a cover plate 2, a folding plate 21, and a fixing component. The cover plate 2 is integrally formed and fixed on the front and rear sides of the top and bottom of the body 1, and the folding plate 21 is integrally formed and fixed on the left and right sides of the top and bottom of the body 1. The connection between the cover plate 2 and the folding plate 21 and the body 1 is bent and creased to facilitate bending of the cover plate 2 and the folding plate 21. Two gripping holes 22 for placing the hands of the staff are opened at intervals on the front and rear sides of the body 1, and one gripping hole 22 is also opened on the left and right sides of the body 1. The fixing component is provided on the folding plate 21 and the cover plate 2 to fix adjacent cover plates 2 and folding plates 21.

[0022] like Figure 1 and Figure 2 As shown, the fixing assembly includes Velcro 31, fixing frame 32, and limiting post 33. A pair of Velcro 31 are symmetrically glued to the outer side wall of the folding plate 21, and four Velcro 31 are glued to the inner side wall of the cover plate 2 at intervals. The Velcro 31 on the folding plate 21 has a rough surface, while the Velcro 31 on the cover plate 2 has a hook surface. Fixing frame 32 is welded to the folding plate 21 and the cover plate 2 near the Velcro 31. Multiple limiting posts 33 are welded to the side of the fixing frame 32 near the adjacent Velcro 31 at intervals along the circumference. Multiple limiting holes 34 are opened on the Velcro 31 along the circumference corresponding to the adjacent limiting posts 33.

[0023] In use, the staff first bends the two folding plates 21 at the bottom of the main body 1 inward, and then bends the two cover plates 2 at the bottom of the main body 1 inward as well, so that the Velcro 31 on the cover plate 2 and the Velcro 31 on the folding plate 21 stick together, thereby sealing the bottom of the main body 1. Then, the raw tobacco leaves are put into the main body 1, and the folding plates 21 and cover plates 2 at the top of the main body 1 are bent inward in sequence to complete the sealing operation of the top of the main body 1. The Velcro 31 sealing method can quickly complete the sealing, effectively reducing the workload of the staff. Moreover, during the repeated use of the turnover box, the fixing frame 32 and the limiting post 33 can limit and fix the corners of the Velcro 31, preventing the corners of the Velcro 31 from being pulled up and curling up during repeated use, ensuring that the Velcro 31 can be used stably for a long time.

[0024] The main body 1, the folding plate 21, and the cover plate 2 are made of PP plastic hollow board material, which enhances their strength, makes them less prone to deformation, and improves the reusability of the turnover box.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, it also includes a fixing block 41, a mounting rod 42, an L-shaped outer shell 43, an L-shaped colored plate 44, a screw 45, and a hand-tightening nut 451. The fixing blocks 41 are fused and fixed to the sides of the left and rear panels of the main body 1 that are close to each other. The mounting rods 42 are fused and fixed to the fixing blocks 41. The L-shaped outer shell 43 is slidably mounted on the two mounting rods 42. The L-shaped colored plate 44 is slidably connected to the side of the L-shaped outer shell 43 that is close to the main body 1. The screw 45 is rotatably connected between the upper and lower sides of the L-shaped outer shell 43. The screw 45 passes through the L-shaped colored plate 44 and is threaded to it. The hand-tightening nut 451 is fused and fixed to the upper end of the screw 45. The left and rear panels of the main body 1 have square openings 46 on the sides that are close to each other. The L-shaped colored plate 44 is made of three layers of cardboard of equal size and different colors. By adjusting the height of the L-shaped colored plate 44, different colors can be displayed at the square openings 46.

[0026] In the initial state, the L-shaped outer shell 43 is not installed on the two mounting rods 42, which makes it easy to fold the main body 1 and save space. When in use, after the staff completes the bending and fixing of the bottom folding plate 21 and cover plate 2 of the main body 1, an L-shaped outer shell 43 is inserted into the two mounting rods 42. Then, the hand-tightening nut 451 is turned to drive the screw 45 to rotate, thereby adjusting the height of the L-shaped colored plate 44 so that the two square openings 46 show different colors, which makes it convenient for the external identification system to identify the turnover box and record the relevant information of the turnover box.

[0027] The mounting rod 42 and the L-shaped housing 43 are fitted with an interference fit to ensure that the L-shaped housing 43 will not slide freely on the mounting rod 42.

[0028] like Figure 3 As shown, it also includes a transparent plate 5, and the transparent plate 5 is welded and fixed at both of the two square openings 46 on the main body 1.

[0029] By setting the transparent plate 5, external debris can be prevented from getting stuck in the square opening 46 and affecting the recognition of the color on the L-shaped color plate 44 by the external recognition system.

[0030] Although this disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made to this disclosure without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
