[0026] The leather laminating equipment described in the present embodiment transmits and loads the skeleton to be laminated by vacuum hot pressing through the mold transmission mechanism 100, and then presses the leather onto the skeleton to be laminated through the laminating and cutting mechanism 200. During this process, the negative pressure mechanism 300 can perform negative pressure adsorption on the laminating space formed by the lifting plate 122 and the moving plate 223 during the relative movement of the two plates, so that the leather in the laminating space can be highly fitted to the surface of the skeleton to be laminated, avoiding problems such as wrinkles and bubbles on the leather during conventional negative pressure connection. Therefore, compared with conventional laminating equipment at this stage, the present application has the advantages of high yield, high controllability, easy operation and wide application range, and has broad application prospects in this field.

[0027] In this embodiment, the frame to be laminated is a concave mold and the cutting mold is a convex mold (not shown in the figure). The edges of the frame to be laminated and the cutting mold are provided with grooves and convex block structures that can fit into each other, so that when the frame to be laminated and the cutting mold are in contact, a closed laminating space can be formed between the two.

[0029] See also Figures 1 to 4As shown, the laminating frame 210 in this embodiment includes a frame body and a bottom plate 211. The bottom plate 211 is provided with a through hole for the cutting mold to pass through. When the cutting mold passes through the through hole, the skeleton to be laminated, the cutting mold, the sealing structure and the bottom plate 211 jointly enclose the closed laminating space. Specifically, the laminating frame 210 in this embodiment is supported on the lifting frame 123, which is used to provide a connection platform for the mold connecting assembly 220. The bottom plate 211 is arranged between the laminating frame 210 and the lifting frame 123. When the mold connecting assembly 220 moves toward the skeleton to be laminated, it can pass through the through hole in the center of the bottom plate 211, thereby improving the sealing degree of the laminating space. In this embodiment, in order to improve the processing efficiency, two mold connecting assemblies 220 are arranged in the horizontal direction. In different embodiments, the number and connection position of the mold connecting assembly 220 can be adaptively adjusted according to actual use requirements, and the present invention does not make specific restrictions on this.

Specifically, the two mold connecting assemblies in this embodiment are both arranged in the connecting slide 221, and are synchronously moved through the connecting slide 221. The movable plate 223 in this embodiment is used to connect the cutting mold, and it is connected to the cutting mold through a plurality of mold clamps 225. Furthermore, in this embodiment, a sealing ring is provided between the movable plate 223 and the cutting mold, and a sealing ring is provided between the lifting plate 122 and the frame to be laminated, thereby further improving the airtightness of the laminated space.

[0031] See also Figure 4 and Figure 5 As shown, in this embodiment, a plurality of mold clamping members 225 are provided, and the plurality of mold clamping members 225 are arranged at intervals around the edge of the movable plate 223 to maximize the connection stability of the movable plate 223 to the cutting mold. Further, the mold clamping member 225 in this embodiment is preferably a clamping locking cylinder. In different embodiments, the mold clamping member 225 can be provided with other structures, quantities or connected to other positions according to actual use requirements, and the present invention does not impose specific restrictions on this.

[0032] This embodiment includes two negative pressure mechanisms 300, and the two negative pressure mechanisms 300 are connected to the inside of the lifting plate 122 and the inside of the moving plate 223 respectively. The lifting plate 122 is provided with a suction hole 224 on the side of the frame to be laminated and the side of the moving plate 223 is provided with a suction hole 224 to create a negative pressure environment inside the laminating space. Furthermore, in the process of negative pressure on the laminating space, only one negative pressure mechanism 300 is in the operation process, and the other is used as a spare element. Specifically, in this embodiment, any of the negative pressure mechanisms 300 includes a vacuum generator 310 and a vacuum pipeline 320, one end of the vacuum pipeline 320 is connected to the working end of the vacuum generator 310, and the other end is connected to the inside of the lifting plate 122 or the moving plate 223, thereby realizing the connection between the negative pressure mechanism 300 and the laminating space.

[0033] In this embodiment, the leather needs to be cooled after the laminating and cutting process is completed so that the colloid on it can solidify, thereby achieving the connection and shaping between it and the frame to be laminated. Furthermore, the shaping piece 400 in this embodiment is preferably an air cooler, which is connected to the lifting frame 123, and its air outlet end is arranged toward the laminating space.

[0034] In addition, the present embodiment also includes a control system, and the mold transmission mechanism 100, the laminating and cutting mechanism 200, and the negative pressure mechanism 300 are respectively connected to the control system. In the actual production and processing process, the operator can control the above structures in real time through the control system, thereby improving the flexibility of the use of the device, and can also preset parameters through the control system, thereby improving the automation of the device.

[0035] The following describes the operation process and principle of the leather laminating equipment in this embodiment:

[0036] First, the operator places the skeleton to be laminated in the mold buffer space 124 through the loading component 110, and connects the corresponding cutting mold to the mold connecting component 220, and then makes the movable plate 223 and the lifting plate 122 move synchronously relative to each other along the height direction of the equipment, so that the skeleton to be laminated and the cutting mold gradually approach the leather to be processed. In this process, a sealed laminating space can be formed between the skeleton to be laminated and the cutting mold through the mutually interlocking structure. At this time, the negative pressure mechanism 300 is started, so that the leather can be tightly attached to the skeleton to be laminated, and the connection between the leather and the skeleton to be laminated is achieved through subsequent pressing, thereby completing the vacuum hot pressing laminating process.

[0037] Next, the movable plate 223 and the lifting plate 122 are relatively separated in the height direction of the equipment, thereby exposing the skeleton to be laminated connected to the leather. At this time, since the colloid between the leather and the skeleton to be laminated is in an unsolidified state, it is necessary to form a stable connection structure between the leather and the skeleton to be laminated through the shaping piece 400, thereby completing the complete laminating connection process between the leather and the skeleton to be laminated.

[0038] In summary, the leather laminating equipment described in the present invention transmits and loads the skeleton to be laminated by vacuum hot pressing through the mold transmission mechanism 100, and then presses the leather onto the skeleton to be laminated through the laminating and cutting mechanism 200. During this process, the negative pressure mechanism 300 can perform negative pressure adsorption on the laminating space formed by the lifting plate 122 and the moving plate 223 during the relative movement of the two plates, so that the leather in the laminating space can be highly fitted to the surface of the skeleton to be laminated, avoiding problems such as wrinkles and bubbles on the leather during conventional negative pressure connection. Therefore, compared with conventional laminating equipment at this stage, the present application has the advantages of high yield, high controllability, easy operation and wide application range, and has broad application prospects in this field.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
