Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

A hot pressing and shaping structure 3 is provided on one side of the turntable 202 on the top of the cabinet 1. A support seat 205 and a lower mold 206 are arranged on the turntable 202, and several lower molds 206 are arranged in a ring. This design enables each lower mold 206 to perform hot pressing operations continuously and orderly. When a lower mold 206 completes hot pressing, the turntable 202 drives the turntable 202 to rotate to switch the processing position. At the same time, the new leather case to be processed can immediately enter the processing area of ​​the hot pressing forming structure 3 for hot pressing, shortening the production cycle, improving the production efficiency of the leather case, and meeting the needs of large-scale industrial production.

[0020] Furthermore, a circular slide rail 204 is installed on the top of the cabinet 1, and a number of sliders 203 are provided on the outer surface of the circular slide rail 204, and the sliders 203 are connected to the bottom of the turntable 202. The sliders 203 and the circular slide rail 204 cooperate with each other to support the turntable 202 to improve the stability of the turntable 202; during the rotation of the turntable 202, if there is no good supporting structure, problems such as shaking and offset are likely to occur, and the cooperation of the circular slide rail 204 and the sliders 203 provides support for the turntable 202, which can effectively disperse the weight of the turntable 202 and the components thereon, making the turntable 202 more stable during rotation.

[0021] Furthermore, a heater is provided in the support base 205, and a conductive slip ring with a through hole is provided on the top of the cabinet 1, and the conductive slip ring with a through hole is located at the rotation center of the turntable 202. The heater contacts the bottom of the lower mold 206, thereby heating the lower mold 206. Before the lower mold 206 reaches the hot pressing and shaping structure 3, the heater heats the raw material to improve processing efficiency. After the hot pressing and shaping structure 3 is hot-pressed, the heater corresponding to the lower mold 206 stops heating. Furthermore, the hot pressing forming structure 3 includes two first support plates 301 installed on the top of the cabinet 1, a second support plate 302 is connected between the two first support plates 301, a first cylinder 303 is installed on the second support plate 302, the piston rod of the first cylinder 303 passes through the second support plate 302 and is connected to the first connecting plate 304, and the first support plate 301 and the second support plate 302 cooperate with each other to support the first cylinder 303.

[0022] Furthermore, the bottom of the first connecting plate 304 is connected to a connecting seat 305, the bottom of the connecting seat 305 is connected to a second connecting plate 306, a number of connecting rods 307 are inserted and connected to the second connecting plate 306, the bottom ends of the several connecting rods 307 are connected to an upper mold 309, the top of the connecting rod 307 is connected to a fixing ring 308, and the fixing ring 308 is fixed to the top of the connecting rod 307 by bolts to achieve the limitation of the connecting rod 307.

[0023] Furthermore, a spring 310 is provided on the outer surface of the connecting rod 307, and the two ends of the spring 310 are respectively in contact with the upper mold 309 and the second connecting plate 306. The elastic force of the spring 310 is greater than the pressure required for hot pressing of the leather case, and the pressure provided by the first cylinder 303 is greater than the elastic force of the spring 310. The spring 310 is used to increase the cushioning of the upper mold 309 when the upper mold 309 descends to the height of pressing with the lower mold 206, thereby reducing the impact force.

[0024] Furthermore, a plurality of guide rods 311 are connected to the bottom of the second connecting plate 306, and a plurality of guide holes 6 are provided on the support seat 205. The positions of the guide holes 6 correspond to the positions of the guide rods 311, and the sizes of the guide holes 6 are adapted to the sizes of the guide rods 311. During the descending process of the upper mold 309, the upper mold 309 can be limited by plugging the guide rods 311 and the guide holes 6, so as to facilitate the alignment of the upper mold 309 with the lower mold 206.

[0025] Furthermore, the top of the first connecting plate 304 is connected to a limiting rod 313, the top of the limiting rod 313 passes through the second support plate 302 and extends above the second support plate 302. The limiting rod 313 can limit the first connecting plate 304 to improve the stability of the lifting of the first connecting plate 304.

[0026] Furthermore, a material taking mechanism 4 is provided on the top of the cabinet 1, and the material taking mechanism 4 is used to take out the leather cover after heat pressing; the material taking mechanism 4 includes a support frame 401 installed on the top of the cabinet 1, the support frame 401 is connected to a third support plate 402, one side of the third support plate 402 is connected to two mounting seats 403, a screw rod 404 is rotatably connected between the two mounting seats 403 through a bearing, a connecting block 405 is threadedly connected to the screw rod 404, and the connecting block 405 is connected to a third connecting plate 406, and the third connecting plate 407 is connected to the third connecting plate 408. The piston rod of the connecting plate 406 is connected to the fourth support plate 408, and several vacuum suction cups 409 are installed on the fourth support plate 408. A second motor 410 is connected between one end of the screw rod 404 and one of the mounting seats 403. A support rod 411 is also connected between the two mounting seats 403, and the outer surface of the support rod 411 is interlaced with the connecting block 405. The second motor 410 can drive the screw rod 404 to rotate, and the rotation of the screw rod 404 can drive the connecting block 405 to move horizontally.

[0027] Furthermore, a notch is provided on one side of the protective cabinet 101, and the position of the material taking mechanism 4 corresponds to the position of the notch. A collecting box 5 is provided on the side of the cabinet 1 close to the notch, and the collecting box 5 is used to collect the thermoformed leather cover.

[0028] When in use, a collection bag is placed on the collection box 5, and the bottom of the front of the protective cabinet 101 is opened. The raw material is placed in the lower mold 206 located at the opening. The raw material is heated, and the first motor 201 drives the turntable 202 to rotate. The turntable 202 drives the lower mold 206 to rotate, so that the corresponding lower mold 206 rotates into the upper mold 309. The first cylinder 303 drives the first connecting plate 304, the connecting seat 305 and the second connecting plate 306 to descend, thereby causing the upper mold 309 to descend to perform hot pressing on the raw material; after hot pressing, the turntable 202 continues to rotate, so that the subsequent lower mold 206 enters the area of ​​the upper mold 309 , and the leather cover that has been hot-pressed is moved to the material-taking mechanism 4, and the second cylinder 407 drives the fourth support plate 408 and the vacuum suction cup 409 to descend, and the leather cover is sucked by the vacuum suction cup 409, and the second cylinder 407 drives the fourth support plate 408, the vacuum suction cup 409 and the leather cover to rise, and the second motor 410 drives the screw rod 404 to rotate, so that the connecting block 405 moves from the notch on the protective cabinet 101 to above the collection box 5, and then moves the leather cover to above the collection box 5, and then the vacuum suction cup 409 releases the leather cover, and the leather cover falls into the collection bag in the collection box 5, and then the connecting block 405 moves back to the protective cabinet 101 to reset.
