Description

Technical Field

[0001] The utility model relates to the technical field of packaging box processing, in particular to a packaging box leather surface pressing device. Background Art

[0002] Leather packaging boxes are sometimes used when packaging some high-end products. When processing the leather packaging box body, it is necessary to stick a layer of leather material (leather surface) on the surface of the box. There are mainly genuine leather, PU leather, artificial leather / synthetic leather, which have 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.

[0003] 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.

[0004] One bonding method is to lay the leather surface flat with the glue-coated side facing up, and then press the side of the packaging box to which the leather surface is to be glued downward toward the leather surface, thereby gluing the leather surface to the packaging box; however, during this process, the leather surface will be simultaneously pulled downward as the packaging box is pressed down. During this process, the leather surface and the packaging box do not fit well, which can easily cause wrinkles, resulting in poor packaging quality and low yield, greatly increasing production costs. Utility Model Content

[0005] The utility model aims to provide a packaging box leather surface pressing device, which tightens the periphery of the leather surface and presses down the packaging box at the same time, so that the two are bonded and the bonding effect is good.

[0006] The implementation method of the utility model is achieved through the following technical solutions:

[0007] A packaging box leather surface pressing device includes a positioning mold, the positioning mold is a square structure, and the center of the positioning mold has a placement cavity for placing the packaging box.

[0008] A plurality of pressing mechanisms for positioning the four corners of the leather surface are respectively provided at the four corners of the positioning mold. The pressing mechanism includes a pressing plate for pressing the leather surface. The pressing plate positions and presses the leather surface through elastic support.

[0009] Furthermore, at least two adjacent frames of the positioning mold are provided with positioning plates on their upper surfaces, and a gap is left between the side of the positioning plate close to the placement cavity and the inner edge of the frame, and the gap forms a step for placing the side of the leather surface.

[0010] Furthermore, the width of the positioning plate is 1 / 3 to 2 / 3 of the width of the frame.

[0011] Furthermore, there is a sufficient interval between the ends of two adjacent positioning plates to leave enough space for placing the clamping mechanism; preferably, the length of the positioning plate is 1 / 3-1 / 2 of the length of the frame, and the positioning plate is centrally arranged on the frame.

[0012] Furthermore, three pressing mechanisms are evenly arranged at each corner of the positioning mold.

[0013] Furthermore, the clamping mechanism also includes a positioning column, a limiting plate arranged on the top surface of the positioning column, and a limiting spring sleeved on the positioning column, the top end of the limiting spring abuts against the bottom surface of the limiting plate, and the clamping plate is arranged at the bottom end of the limiting spring.

[0014] Furthermore, a plurality of positioning wheels are movably provided on the bottom surface of the pressing plate.

[0015] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0016] The utility model first lays the leather surface flat on the frame of the positioning mold, and then presses the side of the packaging box where the leather surface is to be pasted downward until the leather surface is pressed to the bottom of the placement cavity. In this process, the leather surface can be fitted with the bottom surface and the surrounding surface of the packaging box, thereby completing the leather surface processing of the packaging box body; in order to avoid wrinkles on the leather surface and poor fit with the packaging box in the process of pressing the leather surface downward, the utility model is respectively provided with a plurality of pressing mechanisms at the four corners of the positioning mold, and the four corners of the leather surface are pressed by the pressing plate. In this way, in the process of pressing the leather surface downward, the four sides of the leather surface are in a stretched state, and the pressing plate positions and presses the leather surface through elastic support. In this way, as the packaging box is pressed downward, the leather surface gradually moves downward, and the four corners of the leather surface gradually get rid of the elastic constraint, thereby completely releasing the leather surface, and then completely fitting with the packaging box, so that the leather surface and the surface of the packaging box are fitted more neatly and flatly, and the bonding effect is better.

[0021] 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.

[0022] Example 1

[0023] A packaging box leather surface pressing device includes a positioning mold 1, which has a square structure. The center of the positioning mold 1 has a placement cavity 4 for placing the packaging box. The area of ​​the leather surface is larger than the area of ​​the placement cavity 4, and the positive projection of the leather surface can completely cover the placement cavity 4 and leave sufficient margin width; so that the leather surface can be placed on the outer frame of the positioning mold 1 and can completely cover the placement cavity 4; a number of pressing mechanisms 3 for positioning the four corners of the leather surface are respectively provided at the four corners of the positioning mold 1, and the pressing mechanism 3 includes a pressing plate 34 for pressing the leather surface, and the pressing plate 34 positions and presses the leather surface through elastic support.

[0024] It should be noted that the side and inner side of the leather surface of the packaging box to be pasted are coated with glue; when the present invention is in use, the leather surface is first laid flat on the frame of the positioning mold 1, and then the side of the packaging box to be pasted with the leather surface is downward, and the leather surface is pressed tightly until the leather surface is pressed to the bottom of the placement cavity 4. During this process, the leather surface can be fitted with the bottom and peripheral surfaces of the packaging box, thereby completing the leather surface processing of the packaging box body; more specifically, in order to avoid wrinkles on the leather surface and poor fit with the packaging box during the process of pressing the leather surface downward, the present invention The utility model is provided with several pressing mechanisms 3 at the four corners of the positioning mold 1, and the four corners of the leather surface are pressed by the pressing plates 34. In this way, in the process of pressing the leather surface downward, the four sides of the leather surface are in a stretched state, and the pressing plates 34 position and press the leather surface through elastic support. In this way, as the packaging box is pressed downward, the leather surface gradually moves downward, and the four corners of the leather surface gradually get rid of the elastic restraint, thereby completely releasing the leather surface and then completely fitting with the packaging box, so that the leather surface and the surface of the packaging box fit more neatly and flatly, and the bonding effect is better.

[0025] In order to preliminarily position the leather surface first, thereby ensuring the matching of the leather surface and the packaging box and improving the fitting quality; in this embodiment, the upper surface of at least two adjacent frames of the positioning mold 1 is provided with positioning plates 2, and a gap is left between the side of the positioning plate 2 close to the placement cavity 4 and the inner edge of the frame, and the gap forms a step for placing the side of the leather surface. When in use, one side of the leather surface is placed on the step and the side 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 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.

[0026] 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.

[0027] In this embodiment, there is sufficient spacing between the ends of two adjacent positioning plates 2. Preferably, the length of the positioning plate 2 is 1 / 3-1 / 2 of the length of the frame, and the positioning plate 2 is centrally arranged on the frame, which not only plays a role in positioning the leather surface, but also does not hinder the pressing mechanism 3 from pressing the leather surface.

[0028] In this embodiment, three pressing mechanisms 3 are evenly arranged at each corner of the positioning mold 1, so that the leather surface can be pressed and positioned more stably.

[0029] In this embodiment, the clamping mechanism 3 also includes a positioning column 33, a limit plate 31 arranged on the top surface of the positioning column 33, and a limit spring 32 mounted on the positioning column 33. The top end of the limit spring 32 abuts against the bottom surface of the limit plate 31, and the clamping plate 34 is arranged at the bottom end of the limit spring 32. When in use, the end of the clamping plate 34 close to the leather surface is lifted upward, and then the adjusted corner of the leather surface is placed under the clamping plate 34, and the clamping plate 34 is released. At this time, the clamping plate 34 can press the leather surface under the elastic action of the limit spring 32 to ensure that the leather surface is in a tensioned state during the downward pressure, so that it fits more smoothly with the packaging box.

[0030] In other embodiments, a plurality of positioning wheels 35 are movably provided on the bottom surface of the pressing plate 34. In this way, the positioning wheels 35 are in sliding contact with the leather surface to reduce the excessive pressure caused by the surface-to-surface contact between the bottom surface of the pressing plate 34 and the leather surface. As the leather surface is pressed downward, the sliding contact between the leather surface and the positioning wheels 35 also slides and displaces, so that the leather surface gradually separates from the positioning wheels 35 during the downward process, thereby ensuring a complete fit between the leather surface and the packaging box.

[0031] 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.
