[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0023] A plurality of strip-shaped through holes 101a and guide columns 101b are correspondingly opened on each side wall 101 of the U-shaped frame 100. The guide columns 101b are located on both sides of the strip-shaped through holes 101a. There are four guide columns 101b and they are symmetrically arranged. The bottom wall 102 of the U-shaped frame 100 extends toward the outside of the side wall 101 to form a wing plate 103. The strip-shaped through holes 101a are opened horizontally, and the guide columns 101b are perpendicular to the outer wall of the U-shaped frame 100.

[0024] In order to further ensure that the cardboards are transported into the cardboard processing equipment one by one during the loading process, a baffle 104 is provided at one end of the U-shaped frame 100, and the baffle 104 is fixedly connected to the side walls 101 on both sides. The baffle 104 and the bottom wall 102 of the U-shaped frame 100 form a channel 105 for a cardboard conveyor belt. The conveyor belt for conveying cardboard passes through the channel 105 and is arranged above the bottom wall 102 of the U-shaped frame 100. The distance between the lower end of the baffle 105 and the upper side of the cardboard conveyor belt is equal to or slightly greater than the thickness of the cardboard. In this way, when the conveyor belt rotates, under the action of the friction between the conveyor belt and the bottom cardboard, the bottom cardboard is transported away from the U-shaped frame 100, and the remaining cardboards are blocked by the baffle 104 and retained in the placement space of the U-shaped frame 100.

[0025] It should be noted that the feeding device further includes a lifting component 200 and a cardboard grading component 300, the lifting component 200 is arranged on the outside of the two side walls 101 of the U-shaped frame 100, the cardboard grading component 300 is fixedly arranged on the side of the lifting component 200 close to the outer wall of the U-shaped frame, and the cardboard grading component 300 is close to the outer wall of the U-shaped frame. A plurality of cardboard receiving platforms 303 are provided along the vertical direction, and the plurality of cardboard receiving platforms 303 correspond to the plurality of strip-shaped through holes 101a of the outer wall of the U-shaped frame, and each cardboard receiving platform 303 can be inserted into the inner side of the U-shaped frame; when feeding, the cardboard receiving platform 303 in the cardboard grading component 300 is inserted into the cardboard material pile in the placement space, and the cardboard material pile is divided into a plurality of parts, the lifting component 200 rises, and the cardboard grading component 300 rises synchronously with the lifting component 200 to lift the cardboard on the cardboard receiving platform 303, and at the same time, the bottom pile of cardboard in the cardboard material pile is stranded on the cardboard conveyor belt waiting for separation and feeding.

[0026] In some embodiments, the lifting assembly 200 includes a lifting cylinder 201 and a lifting plate 202, and a vertical guide hole 202a is opened on the lifting plate 202. The guide column 101b passes through the guide hole 202a to movably set the lifting plate 201 on the outer side of the side wall 101 of the U-shaped frame 100. The bottom of the lifting cylinder 201 is fixed on the wing plate 103, and the piston end of the lifting cylinder 201 is hingedly connected to the outer side of the lifting plate 202; the telescopic control of the lifting cylinder 201 makes the lifting plate 201 rise or fall within a certain range along the vertical direction under the action of the guide column 101b and the guide hole 202a.

[0027] In some embodiments, the cardboard grading assembly 300 includes a fixed plate 301, which is fixedly connected to the lifting plate 202 through a connecting rod 10, and a plurality of pairs of horizontal cylinders 302 are fixedly provided on the side of the fixed plate 301 opposite to the lifting plate 202, and the pairs of horizontal cylinders 302 correspond to the strip-shaped through holes 101a on the side wall of the U-shaped frame, and the piston rods of the horizontal cylinders 302 pass through the fixed plate 301, and a cardboard receiving platform 303 is fixedly provided at the end of the piston rod, and the cardboard receiving platform 303 can be inserted into or pulled out of the U-shaped frame 100 through the strip-shaped through holes 101a under the control of the horizontal cylinders 302.

[0028] It should be noted that the length of the fixed plate 301 is smaller than the distance between the guide holes 202a at the same height on the lifting plate 202 to ensure that after the fixed plate 301 and the lifting plate 202 are connected by the connecting rod 10, the fixed plate 301 will not affect the up and down movement of the lifting plate 202 under the action of the lifting cylinder 201.

[0029] Preferably, the extension and retraction of the horizontal cylinder 302 can control the cardboard receiving platform 303 to pass through the strip-shaped through hole 101a and be inserted or pulled out toward the inner side of the U-shaped frame; the cardboard receiving platform 303 is in the shape of a right-angled triangle, and one of the right-angled surfaces is fixedly connected to the piston rod of the control cylinder, and the other right-angled surface forms a receiving surface for supporting the cardboard, so that the end of the cardboard receiving platform that first contacts the cardboard material pile is blade-shaped, which facilitates the cardboard receiving platform to be inserted into the cardboard material pile.

[0030] Preferably, the horizontal cylinders 302 at the same height on both sides of the U-shaped frame 100 and the cardboard receiving platform 303 fixedly connected to the horizontal cylinders are cardboard lifting elements at the same level. When in use, several groups of cardboard lifting elements divide the cardboard stack into corresponding groups.

[0031] Preferably, it also includes a control box in which a plurality of control switches are arranged, each control switch controls a primary cardboard lifting element; when separating and loading, the control switch controls the corresponding cardboard lifting element to release the cardboard material group corresponding to the cardboard lifting element, specifically, when the cardboard material pile at the bottom is transported, the control switch controls the cardboard lifting element at the bottom to release part of the cardboard material pile lifted by this group of cardboard lifting elements, and enter the conveyor belt to continue separating and loading, and then gradually control the control switch from bottom to top to make the primary cardboard material pile at the top fall into the cardboard lifting element below, and similarly, until all the cardboard material piles in the cardboard lifting element enter the conveyor belt.

[0032] The utility model also has a sensor connected to the control switch, such as an infrared sensor, which is used to sense whether there is a paperboard pile on the conveyor belt. When the sensor senses that there is no paperboard pile on the conveyor belt, it sends a signal to start the control switch to complete the above operation.
