[0003] Leather packaging makes the box have a better appearance. Common leather materials (leather surface) mainly include genuine leather, PU leather, artificial leather / synthetic leather, which have a good leather appearance and feel, and have good wear resistance, water resistance and chemical resistance; as well as some special paper / leather-filled paper to simulate the texture of leather. These materials are not only environmentally friendly, but also can be made more attractive through printing, embossing, glazing and other processes, while improving the grade of the product and achieving rich visual effects.

[0004] In the prior art, the leather surface is usually adhered to the surface of the packaging box by gluing, that is, professional glue is applied to the outer surface of the packaging box and the inner surface of the leather surface to firmly bond the leather surface and the packaging box together, and the leather surface needs to be kept aligned with the packaging box to have the desired aesthetic effect.

[0005] However, in the process of gluing the leather to the surface of the packaging box, it is difficult to ensure the uniformity of the gluing of each packaging box due to the manual alignment of the leather. In addition, both the leather and the packaging box are coated with glue. If one part of the leather is glued, it is difficult to separate the glued part, resulting in waste of raw materials, low yield rate, and greatly increased production costs. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Example 1

[0027] A positioning device for leather pasting includes a positioning mold 1, which has a square structure and a placement cavity 3 in the center of the positioning mold 1 for placing a packaging box. Positioning plates 2 are provided on the upper surface of at least two adjacent frames of the positioning mold 1. A gap is left between the side of the positioning plate 2 close to the placement cavity 3 and the inner edge of the frame, and the gap forms a step for placing the side of the leather.

[0028] Working principle: When the present invention is in use, the side of the packaging box where the leather surface needs to be pasted is placed upward, and then the packaging box is placed in the placement cavity 3 of the positioning mold 1. It should be noted that the side of the packaging box where the leather surface needs to be pasted and the inner side of the leather surface are coated with glue; then one side of the leather surface is placed on the step and the side edge is pressed against the inner side of one of the positioning plates 2, and then the other side of the leather surface is placed on the other step and the side edge is pressed against the inner side of the other positioning plate 2. At this time, the two side surfaces of the leather surface can be limited by the two positioning plates 2 respectively, and then the leather surface as a whole is positioned; at this time, the leather surface can be pressed downward to fit the leather surface to the packaging box to avoid the phenomenon of crooked pasting caused by the incorrect placement of the leather surface.

[0029] In this embodiment, the width of the positioning plate 2 is 1 / 3 to 2 / 3 of the width of the frame; thereby forming a certain space between the edge of the positioning plate 2 and the edge of the frame to place the leather cover.

[0030] In this embodiment, there is a gap between the ends of two adjacent positioning plates 2; this can form a space for placing a corner of the leather surface, thereby better positioning the leather surface.

[0031] In this embodiment, the height of the placement cavity 3 is greater than the height of the packaging box, so that after the packaging box is placed in the placement cavity 3, a certain height difference is formed between the top surface of the packaging box and the frame. In this way, when adjusting the leather surface, there is a gap between the bottom of the leather surface and the top surface of the packaging box, and the leather surface will not directly contact the packaging box. After adjusting the position of the leather surface, the leather surface can be directly pressed down, so that the fitting of the leather surface is more stable and reliable, and the fitting quality is higher.

[0032] In order to make the packaging box more stable in the placement cavity 3, a positioning component for the packaging box is further provided in the placement cavity 3 in this embodiment. For an open packaging box, the structure of the positioning component is as follows:

[0033] In this embodiment, the inner bottom surface of the placement cavity 3 is provided with a plurality of positioning grooves for the side edges of the packaging box to be embedded, and the plurality of positioning grooves are symmetrically arranged along the center of the placement cavity 3; the positioning grooves include two groups of first positioning grooves 4 arranged along the length direction of the placement cavity 3 and two groups of second positioning grooves 5 arranged along the width direction of the placement cavity 3; and a plurality of the first positioning grooves 4 and the second positioning grooves 5 are provided.

[0034] In this way, multiple positioning grooves can be formed in the length direction and the width direction for the side edges of the open packaging box to be embedded in the positioning grooves. By setting different positioning grooves in different ranges in the length direction and the width direction, multiple positioning grooves for the side edges of packaging boxes of different sizes to be embedded can be formed, which is more stable and reliable to use.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that the structure of the positioning component is different.

[0037] This embodiment is aimed at non-open packaging boxes, and the structure of the positioning component is as follows: the positioning component includes four retractable limit plates 6 evenly arranged along the inner side of the placement cavity 3, one side of a limit plate 6 is connected to the inner side of the placement cavity 3 through a limit spring 7, and the two opposite limit plates 6 are symmetrically arranged relative to the center of the placement cavity 3; in this way, the position of the limit plate 6 can be adjusted according to the size of different packaging boxes. After the packaging box is placed between the four limit plates 6, the elastic action of the limit plate 6 can be used to clamp the packaging box stably.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
