Description

TECHNICAL FIELD

[0001] The utility model relates to the original tobacco leaf box structure, especially to a kind of S-shaped plate original tobacco leaf box structure. BACKGROUND

[0002] The structure optimization of box is evolved from corrugated paper to straight strip hollow plate turnover box, and the structural strength of turnover box is improved due to material replacement from paper to plastic, and the hollow plate box meets certain compression demand, that is, packing in the original tobacco leaf box.

[0003] In the prior art, the hollow plate turnover box with application number "CN202421025901.1" discloses an arc-shaped edge structure, as shown in Figure 2 The original tobacco leaf box disclosed in the prior art adopts a vertical hollow pipe structure, but the original tobacco leaf is compressed in the turnover box, and has a large pressure in the circumferential direction during extrusion, and when the turnover box is placed, as shown in Figure 4 The compressed tobacco leaf will produce extrusion force outwardly to the horizontal side wall of the box, causing the middle part of the box to be deformed outwardly, and the hollow pipe in the existing hollow plate cannot overcome the deformation in the horizontal direction and the deformation in the height direction caused by excessive internal stacking, affecting the subsequent stacking and transportation of the box; as shown in Figure 3 Especially at the bending position between the cover plate and the side plate, the hollow pipe distributed in the width direction increases the difficulty of bending, and a relatively thin bending area needs to be hot-pressed in advance. UTILITY MODEL CONTENT

[0004] The utility model aims to provide a kind of S-shaped plate original tobacco leaf box structure, with the advantages of good bending resistance, low processing cost and good stacking effect.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a kind of S-shaped plate original tobacco leaf box structure, including side plate and cover plate, adjacent side plate is connected in horizontal direction, bending area is formed between the bottom of cover plate and the top of side plate, cover plate and side plate are integrally formed, curved hollow hole is arranged in cover plate and side plate, curved hollow hole is evenly distributed along the height direction of side plate, in the die-cutting unfolded state of cover plate and side plate, the center line of curved hollow hole is flush with the bottom edge of side plate, curved hollow hole forms side opening hole in the side edge of cover plate, side opening hole is evenly distributed along the length direction of the side edge of cover plate, curved hollow hole forms top opening hole in the top edge of cover plate, top opening hole is distributed along the length direction of the top edge of cover plate, and at least one curved hollow hole is reciprocally staggered in the length direction of bending area.

[0006] Preferably, the curved hollow hole is arranged in a wavy shape, the distance between adjacent wave crests of the curved hollow hole is 10-20 cm, and the distance between adjacent wave crest and trough of the curved hollow hole is 5-30 mm.

[0007] By adopting the above technical solution, the distance between the wave crests and the distance between the wave crests and troughs determines the distribution and number of the top openings, and at the same time, cooperates with the bending area, so that it can be better bent, avoiding the problem of too many curved hollow holes in the bending area in the prior art, and avoiding the difficulty of bending.

[0008] Preferably, the side plate and the cover plate are rectangular, the side plate includes a long side plate and a short side plate, the cover plate includes a long cover plate and a short cover plate, the side edges of the long side plate are connected with the side edges of the short side plate respectively, the top edge and the bottom edge of the long side plate are connected with the long cover plate respectively, the top edge and the bottom edge of the short side plate are connected with the short cover plate respectively, the bending area is arranged at the connection position of the long cover plate and the long side plate, and the bending area is also arranged at the connection position of the short cover plate and the short side plate.

[0009] By adopting the above technical solution, the specific structure of the raw tobacco leaf box is disclosed, that is, the box body belongs to a cuboid structure, and it is disclosed that the raw tobacco leaf box is integrally cut from an S-shaped plate.

[0010] Preferably, the side edge of the short cover plate is composed of a round corner, a first inclined edge and a second inclined edge in sequence, the round corner is arranged between the first inclined edge and the top edge of the short cover plate, the top of the second inclined edge is connected with the bottom of the first inclined edge, the bottom of the second inclined edge extends to the bottom of the short cover plate, and the inclination angle of the first inclined edge is greater than that of the second inclined edge.

[0011] By adopting the above technical solution, the round corner avoids cutting hands, the first inclined edge and the second inclined edge are combined, the first inclined edge reduces the friction and scratching with the inner wall of the side plate, and at the same time, it is convenient for the user to lift the cover plate.

[0012] Preferably, the width of the curved hollow hole is a, the width of the bending area is b, the width b of the bending area is greater than the width a of the hollow hole, and the width b of the bending area is less than 1.5-3 times the width a of the curved hollow hole.

[0013] By adopting the above technical solution, at least two curved hollow holes exist in the bending area, which facilitates the bending between the cover plate and the side plate.

[0014] Preferably, inner walls of the hollow hole are formed on both sides of the width direction of the adjacent curved hollow hole, and outer walls of the hollow hole are formed on both sides of the thickness direction of the curved hollow hole.

[0015] The inside of the adjacent curved hollow holes is separated by the hole inner wall, and the inside surface and outside surface of the hole outer wall, i.e., the side plate.

[0016] Preferably, the surface of the hole inner wall is a plane.

[0017] By using the above technical solution, in the case of thin thickness of the side plate and the cover plate, the side plate and the flange do not deform, and the hole inner wall is in a plane state.

[0018] Preferably, the middle part of the hole inner wall forms a pressing angle, the hole inner wall is arranged to be inclined towards the middle part, and the longitudinal section shape of the hole inner wall is in a C type or < type or > type.

[0019] By using the above technical solution, the hole inner wall has a pressing angle, the pressing angle provides the direction of the deformation of the plate under pressure, and when the raw tobacco is loaded, the pressure for pressing the tobacco acts on the side plate or the cover plate, thereby avoiding the fracture of the hole inner wall under pressure or the fracture of the hole inner wall due to deformation in a different direction.

[0020] Preferably, the surface of the hole outer wall is curved inward to form an arc surface, the outside of the hole inner wall is located between adjacent arc surfaces, and an anti-wear line is formed between the adjacent arc surfaces.

[0021] By using the above technical solution, in the plate forming process, the hole outer wall forms an arc surface, thereby forming an anti-wear line, increasing the friction between the raw tobacco boxes and the raw tobacco boxes, and facilitating transportation and stacking.

[0022] In summary, at the bending position of the side plate and the cover plate, i.e., the bending area, the prior art needs to bend multiple transverse curved hollow holes at the bending area position, and since the curved hollow holes reciprocate and intersect at least one, the number of curved hollow holes that need to be bent at the bending area position is reduced, and hot pressing is not required at the bending area position, thereby reducing the processing cost. Compared with the straight line hole, the curved hollow hole has better bending resistance in the transverse and longitudinal directions of the side plate, thereby avoiding deformation of the box in the horizontal and height directions when the raw tobacco is loaded, facilitating stacking and transportation of the box.
