Description

Technical Field

[0001] This utility model relates to the field of turnover box technology, and in particular to a tobacco-specific recyclable turnover box for raw tobacco leaves. Background Technology

[0002] The raw tobacco leaf recycling box is a standardized logistics container specifically designed for the storage, transportation, and turnover of raw tobacco leaves in the tobacco industry. It aims to improve tobacco leaf circulation efficiency, ensure tobacco leaf quality, and meet the tobacco industry's specific requirements for hygiene, safety, and sustainability. Existing recycling boxes use Velcro to connect the inner and outer flaps. However, in some special scenarios, such as when the box is not completely full but the flaps need to be closed to await new tobacco, this means that staff must manually separate the Velcro and open the flaps each time new tobacco is added. This not only causes wear and tear on the hook and loop sides of the Velcro due to repeated friction, significantly reducing adhesive strength, but also greatly increases working time and significantly reduces overall work efficiency. Therefore, this invention proposes a tobacco-specific raw tobacco leaf recycling box to solve the aforementioned technical problems. Utility Model Content

[0003] In order to overcome the technical problems mentioned in the background art, this utility model provides a tobacco-specific raw tobacco leaf recycling box.

[0004] The technical solution of this utility model is as follows: a tobacco-specific raw tobacco leaf recycling box, comprising a long side plate and a short side plate, which are alternately connected. The upper and lower sides of the long side plate are connected to an outer flap, and the upper and lower sides of the short side plate are connected to an inner flap. The long side plate, the short side plate, the outer flap, and the inner flap are integrally formed and are formed into a box body through folding and seamless welding technology. A first connector is symmetrically connected to one side of the inner flap, and a rotating disk is symmetrically rotatably connected to the outer flap. A second connector connected to the first connector is connected to the rotating disk. The second connector is located on the eccentric side of the rotating disk. The rotating disk is rotated by a rotating component, which can change the contact area between the first connector and the second connector. At least one vent hole is provided on the short side plate, and the long side plate may not have a vent hole or may have at least one vent hole.

[0005] As a preferred embodiment of this utility model, a handle cover matching the shape of the vent hole is provided on the vent hole.

[0006] As a preferred technical solution of this utility model, the first connecting member is specifically a female hook and loop fastener, and the second connecting member is specifically a male hook and loop fastener. The rotating disk is driven to rotate by the rotating component, thereby changing the contact area between the male hook and loop fastener and the female hook and loop fastener. Nuts are fixedly connected to the rotating disk and the inner flap. The female hook and loop fastener and the male hook and loop fastener are both installed on the corresponding inner flap and the rotating disk by screws. The side of the female hook and loop fastener and the male hook and loop fastener that contacts the corresponding inner flap and the rotating disk is coated with glue.

[0007] As a preferred technical solution of this utility model, the rotating component includes a first rotating shaft symmetrically rotatably connected to the outer cover, the first rotating shaft being fixedly connected to the rotating disk, a torsion spring being provided between the first rotating shaft and the outer cover, and a second rotating shaft being rotatably connected to the middle of the outer cover. One end of a thin rope is wound on the first rotating shaft, and the other end of the thin rope is fixedly connected to the second rotating shaft.

[0008] As a preferred technical solution of this utility model, a locking disc is rotatably connected to the side of the second rotating shaft near the inner rocker cover. The locking disc is fixedly connected to the second rotating shaft. The side wall of the locking disc is evenly provided with slots. A locking box is fixedly connected to one side of the outer rocker cover. A locking block that cooperates with the slot is slidably connected inside the locking box. An elastic element is provided between the locking block and the locking box. A dial is rotatably connected to the outer rocker cover. The dial is fixedly connected to the second rotating shaft. The dial is located on the side away from the inner rocker cover. An inclined surface is provided on the locking block.

[0009] As a preferred technical solution of this utility model, a second indicator is fixedly connected to the dial, and a first indicator that cooperates with the second indicator is fixedly connected to the outer cover.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This utility model includes components such as a rotating disk, male and female hook and loop fasteners. The rotating disk is driven to rotate by a rotating component, which changes the contact area between the male and female hook and loop fasteners. Thus, when the turnover box is not full of tobacco and needs to be temporarily closed, the rotating disk can be rotated by the rotating component, thereby reducing the contact area between the male and female hook and loop fasteners. This achieves basic fixation, preventing foreign objects from entering, and makes it easier to open when adding tobacco next time, taking into account the practicality of different scenarios. At the same time, when the turnover box is full of tobacco, the contact area between the male and female hook and loop fasteners can be increased to ensure that the outer and inner flaps fit tightly and prevent tobacco from falling out.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0018] As described in the background section, the existing technology has shortcomings. In order to solve the problem that in some special scenarios, such as when the turnover box is not completely filled with tobacco, but the inner flap 103 and the outer flap 104 need to be closed to wait for new tobacco to arrive and then fill the turnover box, it means that every time a new tobacco leaf is added, the staff must manually separate the glued Velcro and open the inner and outer flaps. This not only causes the hook and loop sides of the Velcro to wear easily during repeated friction, resulting in a significant decrease in adhesive strength, but also greatly increases working time and significantly reduces overall work efficiency. Therefore, this application proposes a tobacco-specific raw tobacco leaf circulation turnover box.

[0019] Please see Figures 1-4A tobacco-specific reusable box for raw tobacco leaves includes two long side panels 101 and two short side panels 102, which are alternately connected. Outer flaps 104 are connected to the upper and lower sides of the long side panels 101, and inner flaps 103 are connected to the upper and lower sides of the short side panels 102. The long side panels 101, short side panels 102, outer flaps 104, and inner flaps 103 are integrally formed and assembled into a box body using folding and seamless welding techniques. The seamless welding technique specifically employs ultrasonic welding. The welding technology, which is an existing technology, involves folding the long side plate 101, short side plate 102, outer flap 104, and inner flap 103, and then using seamless welding technology to connect the outermost long side plate 101 and short side plate 102 to form a complete turnover box. A first connecting member is symmetrically connected to one side of the inner flap 103, and a rotating disk 211 is symmetrically rotatably connected to the outer flap 104. A second connecting member, connected to the first connecting member, is connected to the rotating disk 211. The second connector is located on the eccentric side of the rotating disk 211. The rotating disk 211 is rotated by a rotating component, which changes the contact area between the first connector and the second connector. The first connector is specifically a female Velcro 201, and the second connector is specifically a male Velcro 202. The rotating disk 211 is driven to rotate by the rotating component, which changes the contact area between the male Velcro 202 and the female Velcro 201. Thus, when the turnover box is not full of tobacco and needs to be temporarily closed, the rotating disk 211 can be rotated by the rotating component, which reduces the contact area between the male Velcro 202 and the female Velcro 201. This achieves basic fixation to prevent foreign objects from entering, and makes it easier to open when adding tobacco next time, taking into account the practicality of different scenarios. At the same time, when the turnover box is full of tobacco, the contact area between the male Velcro 202 and the female Velcro 201 can be increased to ensure that the outer flap 104 and the inner flap 103 fit tightly and prevent tobacco from falling out.

[0020] The short side panel 102 is provided with at least one ventilation hole 100, while the long side panel 101 may or may not have ventilation holes 100 or may have at least one ventilation hole 100. The ventilation holes 100 have various shapes, such as racetrack shape, circle or rectangle. The ventilation holes 100 are provided with a handle cover 401 that matches the shape of the ventilation holes 100. This arrangement of the ventilation holes 100 can form an air circulation channel, helping the tobacco to stay dry and ventilated, reducing the risk of the tobacco suffocating, and avoiding mold or quality degradation due to moisture. At the same time, the handle cover 401 can be used by workers to hold the tobacco when carrying it, avoiding hand discomfort caused by direct contact with the edge of the box, and improving work efficiency.

[0021] Furthermore, nuts are fixed to the rotating disk 211 and the inner flap 103. The female hook and loop fastener 201 and the male hook and loop fastener 202 are both installed on the corresponding inner flap 103 and the rotating disk 211 by screws. The side of the female hook and loop fastener 201 and the male hook and loop fastener 202 that contacts the corresponding inner flap 103 and the rotating disk 211 is coated with glue. In this way, the double fixing enhances the connection stability between the female hook and loop fastener 201 and the male hook and loop fastener 202 and the corresponding inner flap 103 and the rotating disk 211, and reduces the risk of loosening.

[0022] Furthermore, the rotating assembly includes a first rotating shaft 212 symmetrically rotatably connected to the outer cover 104. The first rotating shaft 212 is fixedly connected to the rotating disk 211. A torsion spring is provided between the first rotating shaft 212 and the outer cover 104. A second rotating shaft 214 is rotatably connected to the middle of the outer cover 104. One end of a thin rope 213 is wound around the first rotating shaft 212, and the other end of the thin rope 213 is fixedly connected to the second rotating shaft 214. When it is necessary to adjust the contact area between the first connecting member and the second connecting member, the second rotating shaft 214 in the middle of the outer cover 104 is rotated. The second rotating shaft 214 will wind the thin rope 213 fixed to it, thereby tightening the thin rope 213 and pulling the first rotating shaft 212 to rotate. As a result, the rotating disk 211 rotates synchronously with the first rotating shaft 212. Since the second connecting member is located on the eccentric side of the rotating disk 211, the rotating disk 211... When rotating, the contact area between the second connector and the first connector can be changed, allowing the second connector to partially or completely contact the first connector. The torsion spring between the first rotating shaft 212 and the outer cover 104 is twisted and stores force when the first rotating shaft 212 rotates. When the second rotating shaft 214 is released, the return force of the torsion spring will drive the first rotating shaft 212 to rotate in the opposite direction, thereby causing the rotating disk 211 to return to its initial position. The thin rope 213 also relaxes and returns to its original position. In this way, through the transmission of the second rotating shaft 214, the thin rope 213 and the first rotating shaft 212, the rotation angle of the rotating disk 211 can be precisely controlled, thereby flexibly changing the contact area between the first connector and the second connector. This meets the needs of different scenarios, such as temporary closing when the turnover box is not full and stable sealing after it is full, thereby reducing the wear of the Velcro and extending the service life of the turnover box.

[0023] Furthermore, a locking disc 215 is rotatably connected to the side of the second rotating shaft 214 near the inner hinge cover 103. The locking disc 215 is fixedly connected to the second rotating shaft 214. Slots 2151 are evenly distributed on the side wall of the locking disc 215. A locking box 216 is fixedly connected to one side of the outer hinge cover 104. A locking block 217 that mates with the slots 2151 is slidably connected inside the locking box 216. An elastic element 218, specifically a spring, is provided between the locking block 217 and the locking box 216. A dial 301 is rotatably connected to the outer hinge cover 104 and is fixedly connected to the second rotating shaft 214. The dial 301 is located on the side away from the inner hinge cover 103. An inclined surface 2171 is provided on the locking block 217. Thus, when the dial 301 is rotated, the second rotating shaft 214 drives the locking disc 215. When the locking disc 215 rotates synchronously, the slot 2151 on the side wall of the locking disc 215 contacts the locking block 217. The inclined surface 2171 on the locking block 217 is squeezed by the slot 2151, causing the locking block 217 to slide into the locking box 216 and compress the elastic element 218. At this time, the locking disc 215 can rotate smoothly. Then, through the transmission components such as the second rotating shaft 214 and the thin rope 213, the rotating disc 211 is driven to adjust the contact area between the first connecting member and the second connecting member. When the rotating dial 301 stops rotating, the restoring force of the elastic element 218 pushes the locking block 217 to slide into the corresponding slot 2151 of the locking disc 215, thereby fixing the locking disc 215 and the second rotating shaft 214 to prevent it from rotating due to external force or the action of the torsion spring, thus maintaining the current position of the rotating disc 211 and the contact area of ​​the connecting member.

[0024] Furthermore, a second indicator 303 is fixedly connected to the dial 301, and a first indicator 302 that cooperates with the second indicator 303 is fixedly connected to the outer cover 104. Thus, when the dial 301 is rotated, the second indicator 303 on the dial 301 will rotate synchronously with the dial 301. By observing the relative position of the second indicator 303 and the first indicator 302, the rotation angle of the rotating disk 211 can be intuitively determined, thereby determining the size of the contact area between the first connector and the second connector.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
