Description

Technical Field

[0001] The utility model relates to the technical field of egg packaging and transportation, in particular to an egg packaging device. Background Art

[0002] As a common fresh food, eggs are generally packaged in a combination of paper egg trays and cartons. The eggs are placed in paper egg trays, which are then placed in cartons for transportation and delivery. However, due to the shaking of the vehicle during transportation, the size of the egg tray is slightly smaller than the internal size of the box, which makes the egg tray easy to shake during transportation, which in turn makes the egg food easily damaged.

[0003] A Chinese utility model patent with announcement number CN220411325U discloses a shockproof turnover box for transporting vaccine eggs. Fixing devices are arranged on the opposite inner walls of the box body. The fixing devices drive the buffer plates to move on both sides of the egg tray, clamp the egg tray on both sides of the egg tray, and prevent the egg tray from shaking during transportation. However, the buffer plates need to move in space when in use. Although the buffer plates can provide a hand or a manipulator to reach in after contraction, thereby facilitating the handling of the egg tray, the box body needs to increase its length in the direction of extension and contraction, making the box body larger in size, while the number of eggs transported does not increase, and the utilization rate of the box space is reduced, resulting in increased transportation costs. For this reason, we provide an egg packaging device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1-9 As shown, the utility model provides a technical solution: an egg packaging device, comprising a box body 1, a plurality of egg trays 3 are arranged inside the box body 1, and at least two opposite side walls of the plurality of egg trays 3 are respectively in contact with the opposite inner walls of the box body 1, and at least two opposite side walls of the egg trays 3 are provided with notches 7, and the width of the notches 7 is less than the length of the corresponding side length of the egg trays 3; a limiting hole 4 is provided at the bottom of the box body 1; a protrusion 5 is provided at the bottom of the egg trays 3, and a positioning hole 6 is provided at the top of the egg trays 3.

[0036] A top cover 2 is provided on the top of the box body 1, and the total height of the top cover 2 and the egg trays 3 is adapted to the inner height of the box body 1, so that the bottom of the top cover 2 is in contact with the top of the topmost egg tray 3, and the egg trays 3 are clamped up and down by the top cover 2 and the bottom inside the box body 1, thereby increasing the overall stability of the egg trays 3.

[0037] When in use, a certain space is formed between the notches 7 on both sides of the egg tray 3 and the side walls of the box body 1, and the inner walls of the box body 1 are all smooth surfaces, which is convenient for taking; the notches 7 can be rectangular, circular, etc., and the top cover 2 and the box body 1 can be installed in a detachable manner such as snap-on connection. One or two groups of egg trays 3 or more can be arranged in the box body 1, and each group of egg trays 3 is kept stable in the horizontal direction by the inner wall of the box body 1 to avoid shaking. At the same time, the egg tray 3 is connected with the top cover 2 at the top through the positioning hole 6 and the protrusion 5, so that the top cover 2 is clamped with the bottom of the box body 1 from top to bottom, and several egg trays 3 are formed into a whole to improve their stability. At the same time, the protrusion 5 of the first egg tray 3 at the bottom is inserted into the limiting hole 4 on the box body 1, further limiting the shaking of the egg tray 3 in the horizontal direction, effectively increasing the inner height while limiting the positioning of the egg tray 3, thereby increasing the number of loads and improving the utilization rate of the internal space of the box body 1.

[0038] The shape and position of the limiting holes 4 match the shape and position of the protrusions 5 at the bottom of the egg tray 3, and the two adjacent egg trays 3 are staggered, and the shape and position of the protrusions 5 match the shape and position of the positioning holes 6, so that the gaps 7 of adjacent egg trays 3 are staggered. When in use, the staggered distribution of the egg trays 3 effectively staggers the gaps 7 on the sides of the egg trays 3, and then the egg trays 3 are transported through the gaps 7.

[0039] There is at least one group of limiting holes 4, and each group of limiting holes 4 has an even number, and each group of limiting holes 4 is distributed in a circular array, and the shape and position of the protrusion 5 at the bottom of the egg tray 3 are adapted to the shape and position of the limiting hole 4, and the shape and position of the protrusion 5 match the shape and position of the positioning hole 6, so that the two upper and lower adjacent egg trays 3 are staggered, and the number of protrusions 5 and positioning holes 6 is the same as the number of one group of limiting holes 4, and the protrusions 5 and the positioning holes 6 are arranged in a rectangular shape, and the diagonal intersection of the rectangle of the protrusion 5 and the diagonal intersection of the rectangle of the positioning hole 6 are both located directly above the center point of the circular array of the limiting holes 4, and the angle between the rectangle composed of the protrusion 5 and the rectangle composed of the positioning holes 6 is ninety degrees, so that the angle between the two upper and lower adjacent egg trays 3 is ninety degrees, and the egg trays 3 are staggered by rotating ninety degrees to facilitate the dislocation and separation of the notches 7, and then the egg trays 3 are taken out in sequence; wherein there are multiple groups of limiting holes 4, and each group is distributed in a circular shape, such as in Figure 3In the embodiment, two rows of egg trays 3 can be placed in the box body 1, and there are two groups of limiting holes 4 under each row of egg trays 3, forming two rings in total, and the first group of limiting holes 4, that is, the outer ring limiting holes 4, has eight holes, which together form two vertically intersecting rectangles, and the intersection of the diagonals of the two rectangles coincides with the center point of the ring circle, and the second group of limiting holes 4 on the inner side has four holes, which are all located at the center of the long side of the rectangle; when in use, through the arrangement of the ring array, when the notches 7 need to be placed on the same side, the egg tray can be rotated by zero degree or one hundred and eighty degrees. The notches 7 on 3 are placed on the same side to facilitate the simultaneous removal of multiple layers at a time. When the notches 7 of different upper and lower layers need to be staggered, the egg trays 3 are rotated at an appropriate angle and then arranged upward in sequence, so that each notch 7 is staggered, so that the egg trays 3 can be taken out in sequence. At the same time, the egg trays 3 are rotated 90 degrees and arranged in a staggered manner, and the protrusions 5 are also located below the egg food, so that the egg food is also staggered, so that the whole composed of multiple egg trays 3 is more evenly subjected to the gravity of the egg food, and the overall stability is further increased.

[0040] The box body 1 includes a bottom plate 101 with a limiting hole 4, and side walls are arranged around the top of the bottom plate 101. The tops of the four side walls can be folded and connected to the bottom of the upper frame 102, so that the box body 1 can be folded and stacked, and the top of the upper frame 102 is connected to the top cover 2; when in use, after the egg tray 3 is removed, the height between the upper frame 102 and the bottom plate 101 is reduced by folding the side walls, thereby reducing the space occupied by the box body 1, improving transportation efficiency and reducing costs.

[0041] The two opposite side walls each include a short side plate 103, the top of the short side plate 103 is hinged to the bottom of the upper frame 102, and the bottom of the short side plate 103 is clamped to the bottom plate 101; the other two side walls each include a first long side plate 104, the top of the first long side plate 104 is hinged to the bottom of the upper frame 102, the bottom of the first long side plate 104 is hinged to a second long side plate 105, and the bottom of the second long side plate 105 is hinged to the bottom plate 101;

[0042] The two opposite sides of the two first long side panels 104 are respectively clamped with the two short side panels 103, and the connection between the first long side panel 104 and the upper frame 102 is lower than the connection between the short side panel 103 and the upper frame 102; the two opposite sides of the two second long side panels 105 are respectively clamped with the two short side panels 103; when in use, the first long side panel 104 and the second long side panel 105 can be hinged, or the first long side panel 104 and the second long side panel 105 can be respectively provided with a connecting structure, and connected by means of a latch, or can be connected by means of a snap buckle, etc., the short side panel 103 and the first long side panel 104 can be connected with the upper frame 102 by setting a connecting structure, and are connected by means of a latch insertion or a hinge, etc., and the second long side panel 105 can be connected with the bottom plate 101 by setting a connecting structure, and are connected by means of a latch insertion or a hinge, etc.

[0043] The edges around the bottom plate 101 extend upward to form a flange, the inner side wall of the flange is connected to the limiting block 8, the limiting block 8 is clamped with the bottom of the short side plate 103, and the top of the flange is higher than the bottom of the short side plate 103, which limits the rotation of the short side plate 103; when in use, the bottom plate 101 is used to achieve staggered stacking after folding, thereby improving the stacking stability; the shape of the bottom plate 101 can be rectangular, square, trapezoidal, etc.

[0044] A card slot 9 is provided on the outer side of the short side plate 103 on the box body 1; a card block 11 is provided on both opposite sides of the first long side plate 104 and the second long side plate 105, and the card block 11 is card-engaged with the corresponding card slot 9;

[0045] During use, after the box body 1 is folded and unfolded, the bottom of the short side panel 103 is positioned by the limit block 8, and the flange on the bottom plate 101 limits the short side panel 103 from continuing to rotate. The connection between the slot 9 and the block 11 makes it necessary to flip and fold the short side panel 103 first when the first long side panel 104 and the second long side panel 105 are folded, so as to ensure the compression resistance of the side wall of the box body 1. At the same time, the egg tray 3 supports the box body 1 inside, thereby supporting the box body 1 and further improving the compression resistance of the box body 1.

[0046] A groove 10 is provided at the edge of the upper frame 102; a convex block 12 opposite to the groove 10 is provided at the bottom edge of the bottom plate 101, so that the convex block 12 is inserted into the groove 10 when stacking;

[0048] The inner wall of the box body 1 adopts a partially hollowed-out plate body, so that the box body 1 forms an open space; the partially hollowed-out plate body design reduces the weight of the box body 1 and facilitates air circulation.

[0049] The inner wall of the box body 1 is made of a solid plate, so that the box body 1 and the top cover 2 form a closed space; the closed space is formed by the solid plate, so that an appropriate box body 1 can be selected according to different egg transportation requirements.

[0050] The staggered notches 7 facilitate the removal of the egg trays 3 from the box body 1. During recycling, the egg trays 3 can be recycled together with the box body 1, or the egg trays 3 can be stacked and placed separately. Then, the short side panels 103 on both sides of the box body 1 are pushed to rotate inward. After the two short side panels 103 and the first long side panels 104 and the second long side panels 105 are disengaged from the limit and moved to the appropriate positions, the upper frame 102 can be pressed downward to fold the first long side panels 104 and the second long side panels 105, thereby reducing the overall volume of the box body 1, thereby increasing the loading capacity of the transport vehicle and reducing the transportation cost.
