Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, specifically to a column for a tobacco leaf transfer frame used in tobacco production. Background Technology

[0002] In tobacco storage and logistics systems, tobacco leaf transfer frames (or tobacco frames) typically consist of a base frame and side rails. To accommodate full-load stacking and save space when empty, the side rails need to be flexible in unfolding and folding. The uprights of the side rails, as the main load-bearing structure, not only require high precision and good stacking stability but also easy and flexible folding. To achieve these functions, the top of the upright needs a large rounded chamfer to facilitate mating with the bottom cup of the upper tobacco frame during stacking; the bottom of the upright needs an angled design to allow for flexible folding and unfolding of the side rails; and the middle of the upright has a limiting pin and a fixing pin to ensure that the center of gravity is vertically aligned when the side rail is unfolded, preventing tipping.

[0003] Currently, the basic processing technology for columns includes sheet metal sorting and rolling, profile forming, top rounding, bottom beveling, and center punching. This involves numerous steps, all requiring mold forming and manual positioning. Dimensional accuracy depends heavily on mold wear and operator attentiveness, resulting in significant errors. Furthermore, burrs are unavoidable during stamping, affecting the appearance. Welded end caps at the bottom bevel require grinding around the weld seam, which is labor-intensive and time-consuming. Significant thermal deformation also contributes to the overall aesthetic issue. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A column for a tobacco leaf transfer frame used in tobacco production includes a plate. The plate is laser-cut with multiple sets of large arc chamfers, electronic tag mounting holes, and bending grooves. The cut plate is bent to form the main body of the column. The large arc chamfers are located at the top of the main body of the column, and the lower end of the main body of the column is bent at an angle through the bending groove.

[0006] Preferably, a limiting pin is provided in the middle of the column body, and a reinforcing plate is installed at the limiting pin on the column body.

[0007] Preferably, the lower end of the column body is bent at an angle by bending the first and second bends at the bending groove.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0013] Please see Figure 1-3 A column for a tobacco leaf transfer frame used in tobacco production includes a plate. The plate has multiple sets of large arc chamfers 2, electronic tag mounting holes, and bending grooves cut by laser. The cut plate is bent to form the column body 1. The large arc chamfers 2 are located at the top of the column body 1. The lower end of the column body 1 is bent to form an angle 3 through the bending groove. A limit pin 4 is provided in the middle of the column body 1. A reinforcing plate is installed at the limit pin 4 on the column body 1. The lower end of the column body 1 is bent to form an angle 3 through the first bend 5 and the second bend 6 at the bending groove. The angle 3 after bending is fixed by welding the side seam weld 7 and the butt seam weld 8. The main column 1 is the core load-bearing component of the side rail of the tobacco leaf transfer frame used in tobacco production. It is the basic carrier of the entire column structure. It is formed by bending the laser-cut sheet material to provide the installation and support foundation for other components such as the large arc chamfer 2, the limiting pin 4, and the reinforcing plate. It directly determines the load-bearing capacity and structural stability of the side rail, ensuring the load-bearing requirements when the tobacco frames are fully loaded and stacked. At the same time, it provides structural support for the flexible folding and unfolding of the side rail. The large arc chamfer 2 is located at the top of the main column 1. Its arc structure is precisely matched with the bottom bowl of the upper tobacco frame, playing a guiding and limiting role in the stacking process, avoiding jamming during stacking, improving the smoothness of stacking operations, and enhancing the overall stability after stacking to prevent the upper tobacco frames from slipping. The bevel 3 is formed by bending the first bend 5 and the second bend 6 at the lower end of the main column 1. This bevel structure eliminates the right-angle interference problem at the lower end of the column, making the side rail The folding and unfolding process is more flexible, reducing friction and collision between parts. It ensures that the side rail can be tightly closed when folded to save storage space, and can be quickly positioned and maintain structural stability when unfolded. The limiting pin 4 is installed in the middle of the column body 1 and is the core limiting component when the side rail is unfolded. It cooperates with the corresponding structure of the cigarette frame base to ensure that the center of gravity of the side rail is vertically aligned with the center of gravity of the cigarette frame after unfolding. This effectively prevents the side rail from tipping over due to the shift of the center of gravity and ensures the structural reliability of the cigarette frame during transportation and stacking. The side seam weld 7 and the butt seam weld 8 are the fixed connection structures after the lower end of the column body 1 is bent to form an angle 3. The two welding positions firmly connect the bent plate structure through the weld, so that the shape and size of the angle 3 remain stable. This avoids structural deformation of the side rail during repeated folding and unfolding. At the same time, it shortens the weld length and optimizes the weld position, reduces the grinding process, and ensures a clean appearance of the column.

[0014] The working principle is as follows: First, the sheet metal is laser-cut to simultaneously process the large arc chamfer 2, electronic tag mounting holes, and bending grooves, ensuring precise matching of all structural dimensions. Then, the sheet metal is bent using a bending machine to form the main column 1, which serves as the core carrier and provides a stable foundation for subsequent component assembly. The large arc chamfer 2 at the top of the main column 1 fits snugly against the bottom bowl of the upper cigarette frame during stacking, achieving rapid positioning through arc guidance and preventing stacking jams. The limiting pin 4 in the middle precisely engages with the corresponding structure of the cigarette frame base after the side rails are unfolded, forcing the side rails' center of gravity to be perpendicular to the overall center of gravity of the cigarette frame. The overlapping structure structurally restricts the side rail from tipping over. The lower end of the main column 1 is precisely bent at the first bend 5 and the second bend 6 to form an angled angle 3 that meets the folding requirements. This angled angle structure reduces the contact interference between the lower end of the column and other components when the side rail is folded and unfolded, making the side rail movement smoother. The angled angle 3 after bending is fixed by welding at the side seam weld 7 and the butt seam weld 8 to ensure the stability of the angled angle 3 shape and avoid structural loosening during repeated folding. At the same time, the reinforcing plate installed at the upper limit pin 4 of the main column 1 further improves the structural strength of the limit part and ensures reliability in long-term use.
