Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a quick-assembly and disassembly structure for an automatic cigarette holder. Background Technology

[0002] In the tobacco curing process, tobacco racks are often used to hang tobacco bundles and clips for curing, ensuring uniform heating and dehydration, and protecting the color and internal quality of the tobacco (such as reducing nicotine and improving the retention rate of aroma substances). Existing tobacco racks in curing barns are mostly integrated welded structures, which present the following problems: First, the disassembly and assembly process requires specialized tools such as gas cutters and heavy-duty wrenches, making the steps cumbersome. This not only makes it difficult to quickly adjust the hanging position and quantity of tobacco according to the size of different varieties and parts of the tobacco (such as upper, middle, and lower leaves) and the requirements of the curing process, but also increases the difficulty of cleaning the curing barn and maintaining the equipment (such as cleaning residual tobacco residue after curing). Therefore, a tobacco rack structure for curing barns that is easy to assemble and disassemble, has precise positioning, and high space utilization is needed to meet the refined production needs of tobacco curing. To this end, a quick-assembly and disassembly structure for automatic tobacco racks is proposed. Utility Model Content

Detailed Implementation The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-6 As shown, this utility model provides a quick-assembly and disassembly structure for an automatic cigarette rack, including a door frame 2 and a cigarette rack 1 connected to the door frame 2. The cigarette rack 1 includes a U-shaped frame formed by a top support 3 and a column 5 fixedly connected together. The column 5 has at least one detachable connection structure spaced apart along the axial direction. The detachable connection structure includes a mating part 6 on the side of the column 5. The cigarette rack 1 also includes a cigarette hanging beam 4, which has multiple sliding holes 7. The sliding holes 7 are equidistantly arranged along the length direction of the cigarette hanging beam 4. The cigarette hanging beam 4 overlaps with the mating part 6 of the column 5 through the sliding holes 7 and can move along the radial direction of the column 5. The detachable connection structure includes a locking member 8, which passes through the sliding holes 7 and is selectively fixed to the mating part 6, realizing the quick assembly and disassembly of the cigarette hanging beam 4 and the adjustment of its radial position.

[0019] The core of the automatic cigarette rack's quick-assembly and disassembly structure includes a door frame 2 for positioning and installation, and a cigarette rack 1 connected to the door frame 2. The basic frame of the cigarette rack 1 is a U-shaped frame, which is formed by a top support 3 and a column 5 fixedly connected together. The column 5 has at least one detachable connection structure along its axial direction for quick assembly, disassembly, and position adjustment. This structure includes a mating part 6 on the side of the column 5. The cigarette rack 1 is also equipped with a cigarette hanging beam 4 for hanging cigarettes, and the cigarette hanging beam 4 has multiple sections equidistantly arranged along its length. The sliding hole 7 allows the cigarette hanging beam 4 to overlap with the mating part 6 of the column 5, thereby enabling it to move radially along the column 5. The detachable connection structure also includes a locking element 8, which passes through the sliding hole 7 and the mating part 6 for selective fixation. This allows for both quick assembly and disassembly of the cigarette hanging beam 4 and adjustment of its position radially along the column 5. The overall structural design balances ease of installation and disassembly with flexibility in the cigarette hanging position, meeting the need for rapid adjustment of the cigarette hanging beam 4 during the use of the automatic cigarette rack.

[0020] The mating part 6 is an oblong through hole opened on the side of the column 5, and the locking part 8 is a U-shaped ring. The U-shaped ring passes through the sliding hole 7 of the smoke hanging beam 4 and the oblong through hole of the column 5 in sequence and is then locked and fixed by a nut.

[0021] The mating part 6 on the side of the column 5 is specifically an oblong through hole, while the locking part 8 used for fixing is specifically a U-shaped ring. During actual assembly, the U-shaped ring will pass through the pre-set sliding hole 7 on the cigarette hanging beam 4 and the oblong through hole on the side of the column 5 in sequence, and then the two are locked and fixed by tightening the nut. On the one hand, with the cooperation of the U-shaped ring and the nut, the disassembly and assembly operations between the cigarette hanging beam 4 and the column 5 can be completed quickly. On the other hand, the cooperation of the oblong through hole and the sliding hole 7 also allows the position of the cigarette hanging beam 4 to be adjusted radially along the column 5 before locking, thereby meeting different cigarette hanging layout requirements.

[0022] The door frame 2 is provided with a positioning block 9, which has a groove or protrusion that fits the bottom of the cigarette rack 1, so as to enable the cigarette rack 1 to be quickly connected and positioned.

[0023] The door frame 2 is equipped with a positioning block 9. This positioning block 9 has a groove or protrusion structure that matches the bottom shape of the cigarette rack 1. Through this groove or protrusion on the positioning block 9 that matches the bottom of the cigarette rack 1, the cigarette rack 1 can quickly form an overlap with the positioning block 9 without additional cumbersome adjustments when assembling with the door frame 2. At the same time, with the precise matching relationship between the groove and the protrusion, the position of the cigarette rack 1 on the door frame 2 is effectively restricted, preventing the cigarette rack 1 from shifting, thereby achieving quick overlap and stable positioning between the cigarette rack 1 and the door frame 2.

[0024] The smoke-hanging beam 4 is provided with a smoke-hanging platform 10 on one or both sides.

[0025] In terms of structure, the cigarette hanging beam 4 has a cigarette hanging platform 10 on one or both sides. Specifically, the middle cigarette hanging beam 4 has a cigarette hanging platform 10 on both sides, while the edge cigarette hanging beam 4 has a cigarette hanging platform 10 on only one side. This structural design can reasonably allocate the cigarette hanging space according to the overall layout of the cigarette rack 1. The middle cigarette hanging beam 4 can achieve bidirectional cigarette hanging by using the cigarette hanging platforms 10 on both sides, while the edge cigarette hanging beam 4 avoids interference with the surrounding structure by using a cigarette hanging platform 10 on only one side. Thus, while ensuring the overall structure of the cigarette rack 1 is regular, the cigarette hanging area is maximized to meet the needs of cigarette hanging in different positions, improving cigarette hanging efficiency and space utilization.

[0026] The bottom end of the column 5 is provided with a fixing component, which is a detachable anchor bolt or expansion bolt, used to quickly fix the column 5 to the ground or disassemble it.

[0027] The column 5 has a fixing component at the bottom of the structure, which is a detachable anchor bolt or expansion bolt. With this structural design, the detachable anchor bolt or expansion bolt can directly act on the connection between the column 5 and the ground. It can quickly and stably fix the column 5 to the ground through the fastening characteristics of the anchor bolt or expansion bolt, preventing the column 5 from shifting or shaking during use. With its detachable property, the anchor bolt or expansion bolt can be easily removed when the position of the column 5 needs to be moved or adjusted, realizing the quick separation of the column 5 from the ground and meeting the dual needs of installation and fixation and disassembly and adjustment of the column 5.

[0028] A connecting block 11 is provided at the connection between the top support 3 and the column 5. The connecting block 11 has an L-shaped structure. The two mutually perpendicular end faces of the connecting block 11 are respectively attached to the end of the top support 3 and the top of the column 5. At least two connecting holes are provided on the contact surface of the connecting block 11. Threaded holes that are adapted to the connecting holes are provided at corresponding positions of the top support 3 and the column 5. The top support 3 and the column 5 are fixed by bolts passing through the connecting holes and threadedly connecting to the threaded holes.

[0029] A connecting block 11 is provided at the connection between the top support 3 and the column 5. This connecting block 11 has an L-shaped structure, with its two mutually perpendicular end faces tightly fitting the end of the top support 3 and the top of the column 5, respectively. At least two connecting holes are provided on both of the fitting surfaces of the connecting block 11. At the same time, the top support 3 and the column 5 have matching threaded holes at the corresponding positions of the connecting holes. During assembly, bolts are passed through the connecting holes of the connecting block 11 and form a threaded connection with the threaded holes on the top support 3 and the column 5, thereby fixing the top support 3 and the column 5. This L-shaped connecting block 11 structure design allows the connecting block 11 to form a precise fitting and positioning with the top support 3 and the column 5. The cooperation of at least two connecting holes and threaded holes, as well as the tightening effect of bolts, can greatly improve the structural stability of the connection between the top support 3 and the column 5, preventing loosening or misalignment during use. At the same time, the threaded connection of the bolts also facilitates the subsequent disassembly, maintenance, or adjustment of the top support 3 and the column 5, taking into account both the stability of the connection and the convenience of disassembly and assembly.

[0030] The process of using the quick assembly and disassembly structure of the automatic cigarette rack of this utility model is as follows: First, fix the column 5 to the ground using the detachable anchor bolts or expansion bolts at the bottom of the column 5; then use the L-shaped connecting block 11 and bolts to fit and fix the top support 3 and the end of the column 5 into a U-shaped frame; next, position the bottom of the cigarette rack 1 by overlapping the groove / protrusion of the positioning block 9 of the door frame 2; then align the sliding hole 7 of the cigarette hanging beam 4 with the waist-shaped through hole of the column 5, insert the U-shaped ring and tighten the nut to fix it; finally, place the tobacco leaves on the cigarette rack 10.
