Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic packaging, in particular to a high-strength paper-plastic loading tray. Background Art

[0002] The loading tray structure plays a role in protecting products and facilitating transportation during the logistics transportation or production transfer process of products. For the transfer in production, after the products are placed on the loading tray, it is necessary to fix or limit the positions of the products to prevent the products from being scattered during transfer, resulting in product damage or the need to re-organize or arrange the products during subsequent processing, thereby affecting the processing efficiency of the products in subsequent processes.

[0003] Among the existing loading trays, there are wooden trays. Since the structure of wooden trays is mostly disposable, they can basically only be scrapped after being damaged and cannot be used again. In addition, the wooden trays themselves are relatively heavy, which is not conducive to rapid transfer. Moreover, the assembly process of wooden trays is relatively complex, requiring additional costs. There are also plastic product trays, but plastic products not only have high costs but also are not easily degradable and are not environmentally friendly. There are also those made of corrugated paper by folding and assembling. In this kind of loading method during the product production process, additional tray assembly processes are required, consuming additional manpower. And it has the disadvantages of relatively low strength, being easily damaged during use, unable to be used twice, and having a relatively simple structure with a poor product fixing effect. Therefore, how to manufacture pollution-free, low-cost tray products that can limit the position of products is a problem that those skilled in the art need to consider. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-strength paper-plastic loading tray, which uses paper-plastic materials and is connected through connection buckles and limited by fixing buckles to solve the problems of non-environmental protection, high cost, or inability to limit the loaded products in the prior art.

[0005] The technical solution of the utility model is: a high-strength paper-plastic loading tray, including a bottom plate. Symmetrically arranged first folding edges and second folding edges are connected to both sides of the bottom plate in the Y direction. Both ends of the first folding edge in the X direction extend to form symmetric third folding edges, and both ends of the second folding edge in the X direction extend to form symmetric fourth folding edges;

[0006] First connection buckles are arranged on the third folding edges, and second connection buckles are arranged on the fourth folding edges; after the first folding edge and the second folding edge are bent, the third folding edge and the fourth folding edge are bent, and the first connection buckles and the second connection buckles are buckled with each other to form the cavity of the tray.

[0007] By adopting the above technical solution, the first folding edge and the second folding edge are folded relative to the bottom plate, the third folding edge is folded relative to the first folding edge, and the fourth folding edge is folded relative to the second folding edge. After folding, only by pressing and buckling the second connecting buckle and the first connecting buckle with each other can a complete loading tray be formed, with convenient operation and greatly improved production efficiency. In addition, before folding to form the tray, multiple semi-finished products can be stacked. When stacking, the first connecting buckles and the second connecting buckles on the upper and lower layers can be positioned simultaneously, ensuring neat stacking. Moreover, the first connecting buckle and the second connecting buckle have a certain limiting effect, which can prevent the semi-finished products from shifting or scattering among each other during transportation, making transportation more convenient.

[0008] Preferably, a plurality of first fixing buckles are arranged in a row on the first folding edge, and a first fixing groove is formed between two adjacent first fixing buckles;

[0009] A plurality of second fixing buckles are arranged in a row on the second folding edge, and a second fixing groove is formed between two adjacent second fixing buckles. When loading products, both ends of the product are respectively clamped in the first fixing groove and the second fixing groove.

[0010] By adopting the above technical solution, after folding to form the tray, the length directions of the first fixing groove and the second fixing groove are parallel to the plane where the bottom plate is located. When placing the product, both ends of the product are respectively along the first fixing groove and the second fixing groove, and from top to bottom until the side of the product abuts against the bottom plate. At this time, the product can be vertically placed in the tray and is limited by the first fixing groove and the second fixing groove. When multiple products are placed in the tray, the products abut against each other, further increasing the stability of the product placement. In addition, the paper-plastic product can be recycled repeatedly, which is more environmentally friendly compared to the traditional wooden or plastic trays.

[0011] Preferably, the first fixing buckle and the second fixing buckle are symmetrically arranged, and the first fixing groove and the second fixing groove are symmetrically arranged.

[0012] By adopting the above technical solution, the symmetrical arrangement of the first fixing buckle and the second fixing buckle is more convenient for placing the product; it is also more conducive to the effective utilization of the space in the cavity.

[0013] Preferably, both the first fixing buckle and the second fixing buckle are protrusions towards the cavity direction, and the first fixing buckle and the second fixing buckle are in the shape of a trapezoidal platform; the cross-sections of the first fixing groove and the second fixing groove are V-shaped or trapezoidal.

[0014] Preferably, both the first fixing buckle and the second fixing buckle are protrusions towards the cavity direction, and the first fixing buckle and the second fixing buckle are in the shape of a triangular prism; and the cross-sections of the first fixing groove and the second fixing groove are V-shaped or trapezoidal.

[0015] By adopting the above technical solution, the openings of the first fixing groove and the second fixing groove are larger on the side closer to the cavity, which facilitates the placement of the product. At the same time, the height of the trapezoidal protrusions of the first fixing buckle and the second fixing buckle can be set according to the actually loaded product, so that when the product is placed on the tray, the first fixing buckle and the second fixing buckle can press against the product on both sides of the product, further ensuring the stability of the product placement. In addition, the setting of the protrusions of the first fixing buckle and the second fixing buckle strengthens the first folding edge and the second folding edge, further increasing the stability of the loading tray.

[0016] Preferably, the sum of the distance between the center of the first connecting buckle and the third folding edge and the distance between the center of the second connecting buckle and the fourth folding edge is equal to the length of the cavity in the Y direction.

[0017] By adopting the above technical solution, when the folding edge of the loading tray is formed and the first connecting buckle and the second connecting buckle are buckled, the side edge of the loading tray formed by the third folding edge and the fourth folding edge is just equal to the length of the side edge on the bottom plate, so that the loading tray reaches the accurate size specification, thereby ensuring the stability of the loading tray and the effective ability to load products.

[0018] Preferably, both the first connecting buckle and the second connecting buckle are protrusions towards the cavity direction;

[0019] One end of the first connecting buckle away from the cavity forms a first groove; one end of the second connecting buckle away from the cavity forms a second groove;

[0020] During connection, the first connecting buckle is embedded in the second groove, or the second connecting buckle is embedded in the first groove.

[0021] By adopting the above technical solution, when the first connecting buckle and the second connecting buckle are connected, they only need to be embedded with each other. The setting of the first connecting buckle and the second connecting buckle protruding towards the cavity direction can also provide support for the products placed in the cavity and close to the third folding edge and the fourth folding edge, so as to ensure the stability of the products in the X-axis direction after being placed on the tray.

[0022] Preferably, both the first connecting buckle and the first groove are trapezoidal; both the second connecting buckle and the second groove are trapezoidal.

[0023] By adopting the above technical solution, the setting of the trapezoid facilitates the demolding of the semi-finished product of the loading tray during pressure filtration forming; on the other hand, when the first connecting buckle is embedded in the second groove or the second connecting buckle is embedded in the first groove, it plays a certain guiding role and can be buckled and connected with less effort.

[0024] Preferably, one or more first connecting buckles are provided, and one or more corresponding second connecting buckles are also provided.

[0025] By adopting the above technical solution, when multiple first connecting buckles and second connecting buckles are provided, the connection strength between the third folding edge and the fourth folding edge can be further increased, thereby further ensuring the stability of the loading tray. In addition, multiple first connecting buckles and multiple second connecting buckles are arranged in one-to-one correspondence. After the third folding edge and the fourth folding edge are folded, only one set of first connecting buckles and second connecting buckles need to be aligned, and the other first connecting buckles and second connecting buckles are automatically in one-to-one correspondence, without a complex alignment and installation process, and the connection forming efficiency of the loading tray will not be increased.

[0026] Preferably, a first folding line is provided between the first folding edge and the bottom plate; a second folding line is provided between the second folding edge and the bottom plate; a third folding line is provided between the first folding edge and the third folding edge; a fourth folding line is provided between the second folding edge and the fourth folding edge.

[0027] By adopting the above technical solution, the folding line can be pressed by a folding edge mechanism. The setting of the folding line facilitates the folding edge forming of the loading tray and is beneficial to further improving the production efficiency.

[0028] Compared with the prior art, the advantages of the present utility model are:

[0029] (1) The loading tray is manufactured by dry pressing paper trays to ensure strength. When the tray is formed, it only needs to be folded along the folding line and then connected by pressing the first connecting buckle and the second connecting buckle. There is no complex assembly procedure, and through the design of the first fixing buckle and the second fixing buckle, the product has a high degree of wrapping, limits the product while increasing the protection of the product;

[0030] Compared with the original corrugated paper tray, the strength is significantly improved and it is not easy to be damaged; compared with wooden or plastic product trays, it can be recycled and reused, is more environmentally friendly and has a lower cost. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0037] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0038] As Figures 1-4 shown, the present utility model is applied to the transfer and transportation of products. After daily necessities such as batteries and scissors are blister-packed, they need to be arranged and placed on a tray during transfer or transportation to facilitate transfer. At the same time, uniform arrangement or stacking is also convenient for counting the quantity, and further facilitates subsequent further packaging or processing. To reduce production costs, the loading tray needs to be lightweight, easy to manufacture, and reusable. Paper-plastic products use one or a combination of waste paper, bamboo pulp, sugarcane pulp, wood pulp fibers, etc. as raw materials, and are made into wet blanks through processes such as loose pulp, grinding pulp, pulp mixing, and vacuum suction filtration molding, and then made into finished products through hot pressing and shaping. No adhesives need to be added during the production process of this product, and it is formed only by the mutual force of the fibers themselves and the structure of the mold itself. It can manufacture paper products with various complex shapes and structures and high dimensional accuracy requirements, has strong strength and plasticity, and is environmentally friendly and biodegradable. Therefore, the present utility model has developed a paper-plastic loading tray, specifically:

[0039] A high-strength paper-plastic loading tray, including a base plate 1. Symmetrically arranged first folding edge 2 and second folding edge 3 are connected to both sides of the base plate 1 in the Y direction. A first folding line 21 is provided between the first folding edge 2 and the base plate 1; a second folding line 31 is provided between the second folding edge 3 and the base plate 1. The first folding edge 2 extends at both ends in the X direction to form symmetric third folding edges 4. A third folding line 41 is provided between the first folding edge 2 and the third folding edge 4, and the third folding line 41 coincides with the side edge of the base plate 1 in the X direction. The second folding edge 3 extends at both ends in the X direction to form symmetric fourth folding edges 5. A fourth folding line 51 is provided between the second folding edge 3 and the fourth folding edge 5, and the fourth folding line 51 coincides with the side edge of the base plate 1 in the X direction. A first connecting buckle 42 is provided on the third folding edge 4, and a second connecting buckle 52 is provided on the fourth folding edge 5.

[0040] In this embodiment, when the loading tray is formed, the first folding edge 2, the second folding edge 3, the third folding edge 4, the fourth folding edge 5 and the bottom plate 1 can all be formed at one time. After forming, they are flat and can be stacked together. When stacking, they are mutually buckled through the first connecting buckle 42 and the second connecting buckle 52 between the upper and lower layers, and can be neatly stacked without manual arrangement, which is convenient for stacking and transportation.

[0041] When the loading tray is in use, the first folding edge 2 is bent 90 degrees along the first folding line 21, and the second folding edge 3 is bent 90 degrees along the second folding line 31; the third folding edge 4 is bent 90 degrees along the third folding line 41, and the fourth folding edge 5 is bent 90 degrees along the fourth folding line 51. At the same time, they are mutually buckled through the first connecting buckle 42 and the second connecting buckle 52. At this time, the cavity 1a of the tray is formed, and the product can be placed in the cavity 1a.

[0042] Furthermore, to ensure that the products can be neatly arranged when placed on the tray and limit their positions to avoid the products from being scattered or knocking against each other during transportation. A plurality of first fixing buckles 22 are arranged in a row on the first folding edge 2. The first fixing buckles 22 are protrusions towards the cavity 1a. At this time, a first fixing groove 23 is formed between two adjacent first fixing buckles 22. Correspondingly, a plurality of second fixing buckles 32 are arranged in a row on the second folding edge 3. The second fixing buckles 32 are also protrusions towards the cavity 1a. At this time, a second fixing groove 33 is formed between two adjacent second fixing buckles 32. The first fixing buckles 22 and the second fixing buckles 32 are symmetrically arranged. Correspondingly, the first fixing grooves 23 and the second fixing grooves 33 are symmetrically arranged.

[0043] When loading the products, the two ends of the products are respectively clamped in the first fixing groove 23 and the second fixing groove 33. The products are neatly arranged, and at the same time, the products are limited by the first fixing groove 23 and the second fixing groove 33 to avoid their movement during transportation. It should be noted that the groove widths of the first fixing groove 23 and the second fixing groove 33, or the distance between two first fixing grooves 23 or two second fixing grooves 33 can be set according to the size specifications of the loaded products. In addition, it should be noted that the ends of the first fixing buckles 22 and the second fixing buckles 32 far from the cavity 1a are both concave towards the cavity 1a.

[0044] In this embodiment, the first fixing buckle 22 and the second fixing buckle 32 are in the shape of a frustum of a pyramid; the cross-sections of the first fixing groove 23 and the second fixing groove 33 are V-shaped or trapezoidal. Of course, the first fixing buckle 22 and the second fixing buckle 32 can also be arranged in the shape of a triangular prism or other structures. The setting of such structures facilitates the demolding of products during the molding of the loading tray and is convenient for production and manufacturing; at the same time, the first fixing groove 23 and the second fixing groove 33 with a V-shaped or trapezoidal setting have a larger opening end at the end close to the cavity 1a, which is more convenient for placing products. That is, after placing the product, it can both limit the product and avoid the situation where the first fixing groove 23 and the second fixing groove 33 are too tightly stuck to the product and are not easy to take out.

[0045] Both the first connecting buckle 42 and the second connecting buckle 52 are protrusions towards the cavity 1a. One end of the first connecting buckle 42 away from the cavity 1a forms a first groove 43; one end of the second connecting buckle 52 away from the cavity 1a forms a second groove (not shown in the figure).

[0046] In this embodiment, both the first connecting buckle 42 and the first groove 43 are in the shape of a frustum of a pyramid; both the second connecting buckle 52 and the second groove are also in the shape of a frustum of a pyramid. This facilitates the molding and demolding of the first connecting buckle 42 and the second connecting buckle 52 during paper-plastic production; when the first connecting buckle 42 is embedded in the second groove or the second connecting buckle 52 is embedded in the first groove 43, it plays a certain guiding role and can make the buckling connection more labor-saving and convenient. It should be noted that the surface of the paper-plastic product is relatively rough and has a certain elasticity. Therefore, the first connecting buckle 42 and the second connecting buckle 52 can be set with the same size specifications, and the first groove 43 and the second groove can also be set with the same size specifications. That is, when the first connecting buckle 42 and the second groove are connected, when the first connecting buckle 42 is pressed into the first groove 43, the first groove 43 can tightly engage the surface of the first connecting buckle 42 and will not be bounced off during normal use; similarly, the same effect can be achieved when the second connecting buckle 52 and the first groove 43 are connected. In addition, the setting of the same size specifications is also convenient for the design and manufacture of the filter press molding die, saves the cost of mold development, and further reduces the production cost. When the first folding edge 2, the second folding edge 3, the third folding edge 4, and the fourth folding edge 5 are folded to form a tray, the first connecting buckle 42 is embedded in the second groove, or the second connecting buckle 52 is embedded in the first groove 43, so that the third folding edge 4 and the fourth folding edge 5 are connected to jointly form two opposite sides of the tray. Therefore, only manual or equipment is needed to complete the folding of the edges and press and buckle between the fixing buckles and the grooves to form a tray. Compared with traditional corrugated paper products, the molding time of the tray is greatly reduced and the production efficiency is improved.

[0047] It should be noted that, in this embodiment, the sum of the distance between the center of the first connecting buckle 42 and the third folded edge 4 and the distance between the center of the second connecting buckle 52 and the fourth folded edge 5 is equal to the length of the cavity 1a in the Y direction, so that when forming the tray, the first connecting buckle 42 and the second connecting buckle 52 can be accurately connected, and the deformation of the cavity 1a is also avoided. In addition, the first connecting buckle 42 and the second connecting buckle 52, and the first groove 43 and the second groove are set with the same size specifications, which is convenient for the manufacture of the forming die. At the same time, when the first connecting buckle 42 is embedded in the second groove or the second connecting buckle 52 is embedded in the first groove 43, they can be tightly fitted to avoid the third folded edge 4 and the fourth folded edge 5 from bouncing open.

[0048] In addition, it should be noted that multiple first connecting buckles 42 can be provided, and correspondingly, multiple second connecting buckles 52 can also be provided. When bending to form the tray, the corresponding connecting buckles and grooves are connected one by one, further increasing the connection stability between the third folded edge 4 and the fourth folded edge 5.

[0049] The paper-plastic loading tray in this embodiment is not limited to being used as a product tray, and can also be applied to other fields. For example, according to the structure in this embodiment, the size of the tray can be changed, or a cover can be added, etc., to be used as a drawer, a box body or a storage box, etc. To avoid excessive details unrelated to the present utility model, the present utility model will not be specifically described.

[0050] The above embodiments are only for explaining the technical concept and characteristics of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit the protection scope of the present utility model. For those skilled in the art, obviously, the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
