[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 8 As shown, a corrugated cardboard hot pressing bonding device comprises a base 1, a hot pressing bonding mechanism 3 is arranged on the top of the base 1, a feeding mechanism 4 is slidably connected to the upper surface of the base 1, a screw transmission mechanism 5 is arranged on one side of the feeding mechanism 4, the screw transmission mechanism 5 drives the feeding mechanism 4 to reciprocate on the base 1, a fixing groove 2 is opened on the upper surface of the base 1, and a discharge port 6 is located on the upper surface of the base 1 at the front side of the fixing groove 2;

[0029] The unloading mechanism 4 includes a silo 401 with openings at the top and bottom. The silo 401 is slidably connected to the top of the base 1. A guide block 402 is fixedly connected to the rear side of the silo 401. A sliding groove 405 is provided at the bottom end of the front wall of the silo 401. A cylinder 403 is fixedly connected to the top of the inner wall of the sliding groove 405. The bottom end bearing of the output shaft of the cylinder 403 is connected to a first movable block 404. The cylinder 403 drives the first movable block 404 to move up and down in the sliding groove 405 through reciprocating motion. After the first movable block 404 moves downward and extends out, it pushes the corrugated cardboard to the discharge port 6, and then the silo 401 moves backward. At this time, the first movable block 404 is inside the sliding groove 405 and above the corrugated cardboard to be hot-pressed and bonded. During the hot-pressing and bonding process, the guide block 402 is always above the corrugated cardboard.

[0030] In this embodiment, a slide rail 7 is provided on the upper surface of the base 1, the front end of the slide rail 7 is connected to the fixed groove 2, a spring 8 is fixedly connected to the front side of the inner wall of the slide rail 7, a second movable block 9 is fixedly connected to the front end of the spring 8, the second movable block 9 is slidably connected to the slide rail 7, and the second movable block 9 pushes the corrugated cardboard forward through the extension of the spring 8;

[0031] In this embodiment, the hot pressing bonding mechanism 3 includes a support frame 303, the top of the support frame 303 is connected to a hydraulic cylinder 301 by screws, the bottom end of the output shaft of the hydraulic cylinder 301 is fixedly connected to a hot pressing bonding plate 302, the hot pressing bonding plate 302 is located above the fixed groove 2, and the output shaft of the hydraulic cylinder 301 drives the hot pressing bonding plate 302 to move up and down to achieve the effect of hot pressing bonding;

[0032] In this embodiment, the screw transmission mechanism 5 includes a servo motor 501, which is fixedly connected to the top of the base 1. The front end coupling of the output shaft of the servo motor 501 is connected to a screw 502, and the front end bearing of the screw 502 is connected to a fixed block 503. The fixed block 503 is connected to the top of the base 1 by screws. A nut block 504 is threadedly connected to the screw 502, and the nut block 504 is welded to the side wall of the silo 401. When the output shaft of the servo motor 501 drives the screw 502 to rotate, the screw 502 drives the silo 401 to move forward and backward through the nut block 504, thereby realizing continuous and automatic loading and unloading, saving manpower, and greatly improving work efficiency.

[0033] In this embodiment, the bottom of the guide block 402 is located above the spring 8, and the bottom surface of the guide block 402 is lower than the top surface of the second movable block 9. The guide block 402 will contact the second movable block 9 and drive it to move forward;

[0034] In this embodiment, the guide block 402 is L-shaped.

[0035] Working principle: When in use, the corrugated cardboard to be processed is placed in the hopper 401, and then the output end of the servo motor 501 drives the screw rod 502 to rotate. At this time, when the screw rod 502 rotates, it drives the hopper 401 to move forward through the nut block 504. The hopper 401 moves forward until the corrugated cardboard falls from the hopper 401 into the fixed groove 2, and then the hopper 401 continues to move forward. At this time, the guide block 402 will contact the second movable block 9 and drive the second movable block 9 to move forward. At this time, the spring 8 will be stretched, and then the second movable block 9 pushes the corrugated cardboard to move forward to the bottom of the hot pressing bonding mechanism 3. At this time, the cylinder 403 contracts and drives the first movable block 404 inside the sliding groove 405. At this time, the unloading mechanism 4 moves backward until the second movable block 9 enters the inside of the slide rail 7 during the retraction process of the spring 8, and then the hydraulic cylinder 301 pushes the hot pressing laminating plate 302 to move downward for hot pressing laminating. After the hot pressing laminating is completed, the hot pressing laminating plate 302 returns to the initial state, and then the unloading mechanism 4 works for the second time. At this time, the cylinder 403 drives the first movable block 404 to move downward and extend, and the first movable block 404 is behind the corrugated cardboard. During the forward displacement of the silo 401, the corrugated cardboard after hot pressing will be pushed to the discharge port 6 by the first movable block 404. Repeating the above process can realize continuous automatic loading and unloading and hot pressing laminating, save manpower, and greatly improve work efficiency.
