DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The front and rear parts of the lower end of the outer surface of the horizontal plate 6 are symmetrically fixedly connected to the guide mechanism 9, which can guide the movement of the pressing mechanism 8, and the lower parts of the two guide mechanisms 9 are fixedly connected to the upper side of the outer part of the pressing mechanism 8. The internal spaced distribution of the pressing mechanism 8 is fixedly connected to a number of adsorption mechanisms 10, which can facilitate the adsorption of the pressed cardboard.

[0024] In order to achieve the purpose of carrying the folding components 3 and the folding forming model 4, refer to Figure 2 The carrying mechanism 2 includes a carrying frame 21, and an annular fixing plate 22 is fixedly connected to the upper portion of the outer surface of the carrying frame 21, which can carry and fix several folding components 3.

[0025] In order to achieve the purpose of folding the cardboard, refer to Figure 3 The folding component 3 includes a support block 31. The left and right walls of the upper inner cavity of the support block 31 are symmetrically provided with guide grooves 32 that communicate with the outside world. A small electric telescopic rod 33 is fixedly connected to the upper front end of the outer surface of the support block 31. A folding mechanism 34 is slidably connected to the upper inner cavity of the support block 31, which can drive the folding mechanism 34 to perform telescopic movement, and the rear piston rod output end of the small electric telescopic rod 33 is fixedly connected to the middle part of the front side of the folding mechanism 34.

[0026] In order to achieve the purpose of driving the folding mechanism 34 to perform telescopic movement, refer to Figure 3 The folding mechanism 34 includes a push plate 341, which can fold the cardboard. The left and right ends of the rear outer surface of the push plate 341 are symmetrically fixedly connected to the limit blocks 342, which can prevent the push plate 341 from falling off in the upper inner cavity of the support block 31, and the two limit blocks 342 are slidably connected to the corresponding guide groove 32 inner cavity.

[0027] In order to achieve the purpose of laminating the cardboard, refer to Figure 4The pressing mechanism 8 includes a lower pressing block 81, and the upper end of the outer surface of the lower pressing block 81 is fixedly connected to a pressing plate 82, which can realize the function of pressing the cardboard after folding, and the middle part of the upper end of the outer surface of the pressing plate 82 is fixedly connected to the lower end of the outer surface of the connecting column 71.

[0028] In order to guide the movement of the pressing mechanism 8, see Figure 4 The guide mechanism 9 includes a fixed sleeve 91, and the inner cavity of the outer surface of the fixed sleeve 91 is slidably connected with a guide column 92, which can guide the lifting and lowering movement of the lower pressing block 81. The four end surfaces of the upper front, rear, left and right sides of the outer surface of the fixed sleeve 91 are fixedly connected to the limiting block 2 93, which can prevent the guide column 92 from falling off when moving downward, and the lower end of the outer surface of the guide column 92 is fixedly connected to the upper end of the outer surface of the pressing plate 82.

[0029] In order to facilitate the adsorption of the pressed cardboard, refer to Figure 4 The adsorption mechanism 10 includes a fixed shell 101, the top wall of the inner cavity of the fixed shell 101 is fixedly connected to a spring 102, the lower part of the outer surface of the spring 102 is fixedly connected to a telescopic column 103, and the lower end of the outer surface of the telescopic column 103 is fixedly connected to a rubber suction cup 104.

[0030] Before the lower pressing block 81 presses the folding forming model 4, since several rubber suction cups 104 protrude from the lower end of the outer surface of the lower pressing block 81, the several rubber suction cups 104 will press down on the bottom wall of the inner cavity of the folding forming model 4 to perform negative pressure adsorption. At the same time, the corresponding telescopic column 103 will compress the spring 102, so that the lower end of the outer surface of the lower pressing block 81 presses the cardboard. When the folding forming model 4 is pulled up, the folding forming model 4 will be pulled upward by the several springs 102.

[0031] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic rod 2 7 and the small electric telescopic rod 1 33 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0032] The working principle of the present invention is as follows: first, the folding forming model 4 is placed in the inner cavity of the carrier frame 21. At this time, the cardboards on the four end faces of the front, back, left and right of the folding forming model 4 will be completely fitted with the side walls of the inner cavity of the carrier frame 21. At the same time, the electric telescopic rod 27 is driven to push the lower pressing block 81 downward through the connecting column 71, and the small electric telescopic rods 1 33 on the left and right sides are driven to push the push plate 341 to slide toward the middle of the inner cavity of the carrier frame 21 until the cardboards on the left and right sides are folded to a certain extent. Then the descending lower pressing block 81 will first press the cardboards on the left and right sides to the left and right walls of the inner cavity of the carrier frame 21. At this time, it is necessary to press the folding forming block located in the inner cavity of the carrier frame 21. The molding model 4 causes the rubber suction cups 104 to fall off from the bottom wall of the inner cavity of the folding molding model 4, causing the lower pressure block 81 to rise to the outside of the inner cavity of the carrying frame 21, and then drives the small electric telescopic rod 1 33 located on the front and rear sides to cause the corresponding two push plates 341 to fold the cardboards on the front and rear sides toward the middle of the inner cavity of the carrying frame 21, and then drives the electric telescopic rod 2 7 again to cause the lower pressure block 81 and the pressing plate 82 to press the cardboards on the front and rear sides. After the pressing is completed, the folding molding model 4 will follow the pull-back of the connecting column 71 under the adsorption force of the rubber suction cups 104 and fall out of the inner cavity of the carrying frame 21, thereby facilitating the removal of the folding molding model 4 that has completed the folding work.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
