Description

Technical Field

[0001] The utility model relates to the technical field of metal packaging boxes, and more specifically to a metal packaging box used in a chain conveying system. Background Art

[0002] Metal packaging boxes refer to thin-walled packaging containers made of stainless steel or carbon steel. They are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrument packaging, industrial product packaging, and arms packaging. The largest number of them are used for food packaging. Compared with other packaging containers, such as plastic, glass, and paper containers, metal packaging boxes are stronger, more rigid, and not easy to break. They are the main containers for large-scale transport packaging. Metal sheets have better barrier properties than any other materials, and have good gas barrier properties, moisture resistance, light blocking properties, and fragrance retention properties. In addition, they are reliably sealed and can reliably protect products.

[0003] However, during the chain conveying of metal packaging boxes, the telescopic rod of the packaging line clamp cannot reach the positioning point during operation and generates an alarm due to the obstruction of the reinforcing iron bars of the box. At the same time, due to the limitation of the existing reinforcing iron bars, there is only one type that is suitable for manual forklifts, mechanical forklifts or online plate chain conveying, resulting in low adaptability. Personnel are required to deploy the packaging boxes according to different conveying conditions each time, which brings great inconvenience to the existing system. Utility Model Content

[0034] Example:

[0035] See also Figure 1-Figure 5 A metal packaging box for a chain conveyor system, comprising a base 1 and a box body arranged at the upper end of the base 1, the box body comprising two oppositely arranged side panels 1 2, two oppositely arranged side panels 2 3 and a top plate 5, the side panels 1 2 and the side panels 2 3 are connected end to end to form a box body space, the top plate 5 is arranged on the top of the two groups of side panels 1 2 and the side panels 2 3; locking members 4 are arranged on the inner walls of both sides of the side panels 1 2, and the locking members 4 are used for limiting and fixing the side panels 2 3;

[0036] The base 1 comprises a bottom plate 11, a middle foot 12 is fixedly connected to the center end of the lower side of the bottom plate 11, side foot 13 are fixedly connected to the lower sides of the bottom plate 11, a through slot 14 is provided at the bottom of the side foot 13, the middle foot 12 is located at 555mm from the center line of the bottom plate 11, the through slot 14 at the bottom end of the side foot 13 corresponds to the chain track position 50-70mm and 1030-1050mm, the side ends of the middle foot 12 and the side foot 13 are both provided with a through slot 2 15, and two reinforcing iron bars 19 are fixedly connected between the inner walls of the through slot 2 15;

[0037] The length of the bottom plate 11 is 1440 mm, and the two reinforcing iron bars 19 are symmetrically arranged 390 mm inward from the outer walls on both sides, with a tolerance of ±2 mm;

[0038] The layout of the reinforcing iron bar 19, the middle foot seat 12 and the side foot seat 13 together form a three-dimensional structure that avoids interference from the clamp and is suitable for multi-directional fork installation.

[0039] In the technical solution of the utility model, a modular splicing box structure is innovatively adopted, and the loading convenience and transportation adaptability of the box are significantly improved through the assembly of standardized components. In view of the fork loading interference problem existing in traditional metal packaging boxes, this design precisely optimizes the layout of the bottom reinforcement iron bars: taking the outer edges of both sides of the box as the reference plane, the reinforcement iron bars are positioned at the symmetrical axis position of 390mm inward on both sides (the tolerance is controlled within ±2mm). This engineering design not only effectively avoids the operating area of ​​conventional clamps, but also improves the structural strength of the box through stress distribution reconstruction.

[0040] In terms of conveying system integration, the middle foot and the double side foot configured at the bottom of the box body accurately correspond to the 2cm wide chain track of the plate chain conveyor, forming a three-point positioning support system, which can improve the conveying stability by more than 35%. In addition, this structural optimization enables the packaging box to adapt to multiple working conditions at the same time - manual forklifts can achieve two-way barrier-free forking, mechanical forklifts support fork positioning in any direction on all four sides, and maintain dynamic compatibility with the online conveying system. Actual production data shows that this design scheme shortens the single-box transfer cycle to less than 45 seconds, and the comprehensive conveying efficiency is improved by about 40% compared with the traditional structure, without affecting the operating parameters of the original conveying system.

[0041] See also Figure 2-Figure 4 A circular groove 16 is provided at the upper end of the bottom plate 11, and the bottoms of the side panels 1 2 and 3 are inserted into the circular groove 16. A plurality of evenly distributed movable grooves 17 are provided at the bottom end of the circular groove 16, and screws 18 are inserted into the interior of the movable grooves 17, and the screws 18 are threadedly connected to the screw holes at the bottoms of the side panels 1 2 and 3.

[0042] During use of the present solution, the two oppositely disposed side panels 12 can be first inserted into the circular groove 16, and then the two oppositely disposed side panels 23 can be inserted into the circular groove 16, and the two side panels 23 are located on the outside of the side panel 12, so that the positions of the side panels 12 and 23 are pre-fixed in advance to form a box space, and then the screws 18 can be movably inserted into the movable groove 17 through the screw holes at appropriate positions of the side panels 12 and 23, so as to position the bottom positions of the side panels 12 and 23.

[0043] See also Figure 1 and Figure 5 The locking member 4 includes a positioning plate 41 fixedly connected to the side walls of both sides of the side plate 2, and the side end of the positioning plate 41 is fixedly connected to the positioning plate 42. The side end of the side plate 2 is provided with a through hole 43, and a limiting bolt 44 is installed between the inner walls of the through hole 43. One end of the limiting bolt 44 is located between the inner walls of the positioning plate 41 and the positioning plate 42. A positioning hole 45 is provided on one side of the side plate 23.

[0044] During use of the present solution, before pre-fixing the positions of side panels 1 2 and 2 3, the personnel first lifts up the limit pin 44, causing the limit end on the other side of the limit pin 44 to rotate 90° in the through hole 43, so that the limit end of the limit pin 44 and the side panel 1 2 are in the same vertical plane at this time, and then the side panel 2 3 is affixed to the outer side of the side panel 1 2, thereby causing the limit end of the limit pin 44 to be inserted into the positioning hole 45. After the side panels 1 2 and 2 3 are affixed, the personnel presses down the limit pin 44 again, so that the limit end of the limit pin 44 returns to its initial shape, and the pressing end of the limit pin 44 is again located between the inner walls of the positioning plates 1 41 and 2 42, completing the storage, thereby presenting a horizontal plane, thereby realizing the positioning of the positions of the side panels 1 2 and 2 3.

[0045] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
