[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an automatic box unpacking machine, including an L-shaped base plate 100 and a U-shaped frame 101; a material placement structure is connected above the L-shaped base plate 100, a slide 300 is slidably installed inside the U-shaped frame 101, a feeding structure is connected to the slide 300, a fixed frame 400 is installed on one side of the U-shaped frame 101, and a folding plate structure is connected to the fixed frame 400.

[0023] Furthermore, the material placement structure includes a material placement plate 200 and a screw jack 201. The screw jack 201 is mounted on an L-shaped base plate 100 and has several screws 202. Threaded seats 203 are threaded onto the screws 202 and mounted on the material placement plate 200. A bidirectional screw 204 and an adjusting screw 208 are rotatably mounted inside the L-shaped base plate 100. A first motor 205 and a second motor 209 are mounted on opposite sides of the L-shaped base plate 100. The output end of the first motor 205 is mounted on the bidirectional screw 204, and the output end of the second motor 209 is mounted on the adjusting screw 208. Two U-shaped positioning rods 206 are threaded onto the bidirectional screw 204, and a movable stop bar 207 is threaded onto the adjusting screw 208. The two U-shaped positioning rods 206 and... The movable stop bars 207 are all slidably installed inside the L-shaped base plate 100. By turning on the screw jack 201, the screw jack 202 can be rotated. When the screw jack 202 rotates, it can drive the material plate 200 and the stacked cardboard to rise through the threaded engagement with the screw seat 203. Turning on the motor 1 205 can drive the bidirectional screw 204 to rotate. The rotating bidirectional screw 204 can drive the two U-shaped positioning rods 206 to move towards each other or away from each other, which can adjust the distance between the two U-shaped positioning rods 206. When the motor 2 209 is turned on, the adjusting screw 208 can rotate. The rotating adjusting screw 208 can drive the movable stop bar 207 to slide. By controlling the position of the movable stop bar 207 and the U-shaped positioning rods 206, the stacked cardboard can be positioned, and it can accommodate cardboard of different sizes.

[0024] Furthermore, a T-shaped strip 210 is slidably installed inside the movable stop bar 207. The T-shaped strip 210 is installed on the inner wall of the L-shaped base plate 100. The material plate 200 has a sliding hole 211 and several sliding holes 212 inside. The movable stop bar 207 is slidably installed inside the sliding hole 211, and the U-shaped positioning rod 206 is slidably installed in the corresponding sliding hole 212. When the U-shaped positioning rod 206 moves, it can slide in the sliding hole 212. When the movable stop bar 207 moves, it can slide in the sliding hole 211, so that the movement and adjustment of the U-shaped positioning rod 206 and the movable stop bar 207 will not affect the lifting and lowering movement of the material plate 200.

[0025] Furthermore, the feeding structure includes several pneumatic suction cups 301, which are installed inside the slide 300. A threaded slide block 302 is installed on one side of the slide 300, and a linkage screw 303 is installed in the internal threads of the threaded slide block 302. The linkage screw 303 is rotatably installed inside the slide 300. A servo motor 304 is installed on one side of the slide 300, and the output end of the servo motor 304 is installed on the linkage screw 303. A conveyor belt 305 is installed on the slide 300. The conveyor belt 305 is located below the pneumatic suction cup 301. When the topmost cardboard comes into contact with the pneumatic suction cup 301, the pneumatic suction cup 301 can hold the cardboard in place. Then, the servo motor 304 is turned on to drive the linkage screw 303 to rotate. The rotating linkage screw 303 can drive the threaded slide 302 to slide through the threaded engagement with the threaded slide 302, so that the threaded slide 302 drives the slide 300 to move. The slide 300 can then drive the pneumatic suction cup 301 and the adsorbed cardboard to move.

[0026] Furthermore, the slide 300 has a guide groove 306 inside, and the threaded slide 302 is slidably installed inside the guide groove 306. When the threaded slide 302 moves, it can slide in the guide groove 306, thereby preventing the position of the threaded slide 302 from shifting.

[0027] Furthermore, the folding structure includes two electric push rods 401 and two electric push rods 402. The two electric push rods 401 and 402 are evenly installed on the fixed frame 400. The output ends of the two electric push rods 402 are equipped with push plates 403, and the output ends of the two electric push rods 401 are equipped with L-shaped push plates 404. The interior of the two L-shaped push plates 404 is equipped with glue guns 405. The four paper covers at one end of the cardboard will move into the fixed frame 400 under the action of the pneumatic suction cup 301. At this time, the electric push rods 401 on both sides can be opened first to move the L-shaped push plates 404 and squeeze the paper covers, so that the paper covers are flipped and folded. At the same time, glue guns 405 can be used to spray adhesive onto the flipped cardboard. Then, the electric push rods 402 on both sides can be opened to move the push plates 403 and squeeze the other two paper covers, so that the other two paper covers come into contact with the folded paper covers and are glued together with adhesive, thus completing the bottom sealing operation.

[0028] Furthermore, the folding structure also includes an electric push rod 3 406, the output end of which is equipped with a pressing plate 407, and a support plate 408 is installed on the electric push rod 3 406. The support plate 408 is installed on one side of the carriage 300. When the electric push rod 3 406 is turned on, it drives the pressing plate 407 to descend. The descending pressing plate 407 will press against the cardboard, causing the cardboard to fold along the crease.

[0029] The working principle is as follows: The screw jack 201 is activated to control the rotation of the screw 202. When the screw 202 rotates, it engages with the threaded seat 203, causing the material plate 200 to move up and down. As the material plate 200 rises, it lifts the stacked cardboard, bringing the top cardboard into contact with the pneumatic suction cup 301. The pneumatic suction cup 301 then holds the cardboard in place. The servo motor 304 is then activated to rotate the linkage screw 303. The rotating linkage screw 303 engages with the threaded slide 302, causing the slide 302 to slide within the guide groove 306. This causes the slide 302 to move the carriage 300, which in turn moves the pneumatic suction cup 301 and the held cardboard. Simultaneously, the electric push rod 406 is activated, causing its output end to lower the extrusion plate 407. The descending extrusion plate 407 presses against the cardboard, causing it to fold along the creases. Figure 4 In this state, the four paper covers at one end of the cardboard will move into the fixed frame 400 under the action of the pneumatic suction cup 301. At this time, the electric push rods 401 on both sides can be opened first. The output end of the electric push rod 401 drives the L-shaped push plate 404 to move and squeeze the paper covers, so that the paper covers are flipped and folded. While the L-shaped push plate 404 is moving, glue gun 405 can be used to spray adhesive onto the flipped cardboard. Then, the electric push rods 402 on both sides can be opened, so that the electric push rod 402 drives the push plate 403 to squeeze the other two paper covers, so that the other two paper covers come into contact with the folded paper covers and are glued together with adhesive, thus completing the bottom sealing operation of the carton. After completion, control the pneumatic suction cup 301 to detach from the suction of the carton, so that the carton can fall onto the conveyor belt 305 and be transported by the conveyor belt 305.

[0030] By turning on motor 205, the bidirectional lead screw 204 can be rotated. The bidirectional lead screw 204 has two threads facing opposite directions, and the threads are adapted to the U-shaped positioning rods 206. Therefore, the rotating bidirectional lead screw 204 can drive the two U-shaped positioning rods 206 to move towards each other or away from each other through the threaded engagement with the two U-shaped positioning rods 206, thereby adjusting the distance between the two U-shaped positioning rods 206. When motor 209 is turned on, the adjusting lead screw 208 can be rotated. The rotating adjusting lead screw 208 can slide on the T-shaped strip 210 through the threaded engagement with the movable stop 207. By controlling the position of the movable stop 207 and the U-shaped positioning rods 206, the stacked cardboard can be positioned, and it can accommodate cardboard of different sizes.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. The circuits, electronic components and modules involved in the present invention are all prior art and can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by the present invention does not involve improvements to software and methods.
