[0001] This utility model relates to the tobacco industry and the field of machinery manufacturing and processing, and in particular to a bent tobacco storage and transportation frame. Background Technology

[0002] Traditional tobacco frame manufacturing methods involve cutting a rectangular tube into multiple sections and then joining them together. This process is complex and time-consuming. Furthermore, welding or other connection methods require multiple positioning steps, resulting in insufficient precision and strength. Drainage holes and pin holes need to be punched on various surfaces, leading to dimensional errors during material cutting. Tooling fixtures are required to ensure dimensions during splicing, and the weld seams are prone to deformation, increasing processing time and labor costs. Therefore, a bent tobacco storage and transportation frame is proposed. Summary of the Invention

[0003] This utility model addresses the problems mentioned above, where current equipment and existing technology lack suitable solutions. Traditional splicing requires tooling fixtures to ensure dimensions, increasing processing time and labor costs. It provides a bent tobacco storage and transportation frame that, being a single rectangular tube, is already positioned, eliminating the need for segmented welding. The structural design saves manpower and improves efficiency. Combined with multiple fixing methods, the connection is stable and adaptable to different assembly needs, improving production efficiency and effectively solving the problems mentioned in the background art.

The radius of curvature R of the arc crease and the thickness T of the profile satisfy R:T=1:2.

[0006] The angle between the first folded surface and the second folded surface is 90 degrees.

[0007] The outer surface of the profile is provided with a pin hole.

[0008] The first folded surface and the second folded surface are bonded together by guide grooves and then fixed by welding.

[0009] Compared with existing technologies, this utility model has the following advantages: The tobacco storage and transportation frame possesses multiple advantages. In terms of structural design, the folding opening and guide groove facilitate bending and forming, saving manpower and improving efficiency. Combined with various fixing methods, the connection is stable and adaptable to different assembly needs.

[0016] 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.

[0017] As shown in Figures 1-5, this utility model provides a bent tobacco storage and transportation frame, including a profile 1. The profile 1 is divided by multiple folding openings 2 to form a first folding surface 7 and a second folding surface 8. A guide groove 6 is radially opened between the first folding surface 7 and the second folding surface 8. The first folding surface 7 and the second folding surface 8 are fitted together through the guide groove 6. A drainage hole 4 is provided on the inner bottom surface of the profile 1. Arc creases 5 are opened at both ends of the guide groove 6. The radius of curvature R of the arc crease 5 and the thickness T of the profile 1 satisfy R:T=1:2.

[0018] This tobacco storage and transportation frame uses high-strength profiles 1, such as square or round tubes, as the manufacturing base material. The entire profile 1 is placed horizontally and stably on the worktable of a laser tube cutting machine, where multiple folding openings 2 are precisely cut. These folding openings 2 divide the profile 1 into a first folding surface 7 and a second folding surface 8. The profile 1 can then be bent into a frame structure. To reduce the difficulty of manual folding operations, improve processing efficiency, and ensure precise alignment of the first folding surface 7 and the second folding surface 8 during folding, guide grooves 6 are created radially between the two folding surfaces. Operators only need to apply manual force to quickly complete the frame bending and forming. This frame is highly versatile, suitable not only for tobacco transportation but also for the flexible transportation of other materials. Considering the weighing requirements in actual use, the frame is clearly marked with its net weight during production, facilitating direct use in subsequent tobacco weighing without the need for additional frame weight calculations. To address the potential issue of rainwater backflow during outdoor storage, drainage holes 4 are machined on the inner bottom surface of profile 1. This not only allows for timely drainage of accumulated water but also optimizes stress distribution during folding due to the through-hole structure, aiding in bending operations. Furthermore, since edge burrs generated during laser cutting can affect the fitting accuracy of the folded surfaces, arc-shaped creases 5 are added at both ends of the guide groove 6 during cutting. This not only effectively removes cutting burrs but also enhances the tightness of the fit between the first and second folded surfaces, creating favorable conditions for subsequent work. The ratio of the radius of curvature R of the arc-shaped crease 5 to the thickness T of profile 1 is R:T=1:2. If the radius of curvature R is too large, it will result in excessive space occupied at the fold, affecting the overall structural compactness of the frame. If R is too small, it can easily cause stress concentration in the profile during folding, leading to cracks or even breakage. Controlling the ratio to 1:2 ensures even stress distribution on the profile during folding, guaranteeing smooth folding operations while ensuring the formed frame possesses good structural strength and stability, meeting actual storage and transportation needs while extending the frame's service life.

[0019] The angle between the first folded surface 7 and the second folded surface 8 is 90 degrees.

[0020] The included angle between the first folded surface 7 and the second folded surface 8 is flexible and adjustable, and can be customized according to actual application needs. For example, when constructing a quadrilateral frame, the included angle between adjacent folded surfaces is cut at 90 degrees; when a triangular frame structure is required, the included angle is set to 60 degrees; and the included angle of the folded surfaces of a pentagonal frame is cut at 108 degrees, so as to meet the design requirements of different geometric shapes of the frame.

[0021] The outer surface of the profile 1 is provided with a pin hole 3.

[0022] The outer surface of profile 1 undergoes precise processing to create pin holes 3 of specific size, shape, and distribution. These pin holes 3 provide connection interfaces for the assembly and integration of the tobacco storage and transportation frame with other components or auxiliary equipment. By inserting the pins into the holes, a stable combination of the frame and surrounding accessories can be achieved, meeting the structural strength and integrity requirements of the frame during storage and transportation, while also facilitating flexible adjustments and modifications to the frame according to actual needs.

[0023] The first folded surface 7 and the second folded surface 8 are fixed by welding after being attached together through the guide groove 6.

[0024] In this tobacco storage and transportation frame structure, the first folded surface 7 and the second folded surface 8, formed by dividing the profile 1 through multiple folding openings 2, are fitted together by guide grooves 6, and can be fixedly connected in various ways. The two folded surfaces can be fused into a strong whole through welding; alternatively, special metal clips can be embedded in the guide grooves, utilizing the elastic deformation of the clips and the engagement of the grooves for quick fixation; or threaded holes can be opened at corresponding positions, and high-strength bolts and nuts can be used for fastening, enhancing the stability of the connection; or high-strength structural adhesive can be applied to the surface of the guide groove 6, allowing the two folded surfaces to be tightly bonded through adhesive action. This meets different usage scenarios and assembly requirements, ensuring the structural strength and reliability of the frame during the storage and transportation of tobacco and other materials.

[0025] The process of using the bent tobacco storage and transportation frame of this utility model is as follows: First, according to actual needs, high-strength profiles 1 such as square tubes and round tubes are selected. Folding openings 2, guide grooves 6, drainage holes 4, and arc creases 5 at both ends are cut on a laser tube cutting machine to form a first folded surface 7 and a second folded surface 8. The first folded surface 7 and the second folded surface 8 are then joined together through the guide grooves and fixed using welding, snap-fit, bolts and nuts, structural adhesive, etc. After bending and shaping, pins are inserted into the pin holes 3 on the outer surface of the profile 1 as needed, and then connected and assembled with other components. The assembled frame can be used to transport tobacco or other materials. If water accumulates during use, the drainage holes 4 can drain the water in time, ensuring the safety of the materials.
