[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] A cardboard automatic loading machine for a corrugated paper printing machine includes a mobile vehicle 1 and a board loading device. In the present invention, the mobile vehicle 1 is installed on the track 25 on the ground. In the present invention, rollers cooperating with the track 25 are installed at the bottoms of both the mobile vehicle 1 and the support plate 3, and the mobile vehicle 1 is driven by a motor to move along the track 25. A conveyor 2 is installed on the top of the mobile vehicle 1, and the conveyor 2 is used to convey corrugated cardboard to the corrugated paper printing machine. One end of the conveyor 2 can be hinged to the mobile vehicle 1, and at the same time, the conveyor 2 can be driven by an oil cylinder to rotate up and down relative to the mobile vehicle 1.

[0023] The right side of the mobile vehicle 1 is connected to the support plate 3, and the support plate 3 is connected to the lower side of the mobile vehicle 1. In the present invention, the support plate 3 serves to support the lifting plate and the pusher plate support 17. During operation, a tray with corrugated cardboard at a certain height is placed on the lifting seat 4 on the support plate 3.

[0024] The board loading device includes a lifting seat 4, a drawer plate cylinder 5, a pusher plate cylinder 6, and an upper baffle 12.

[0025] The lifting seat 4 is used to lift the tray on which the corrugated cardboard with a certain height is placed. The lifting seat 4 is liftably installed on the support plate 3 and is driven to lift by a driving assembly. The driving assembly includes a lead screw motor 18 installed on the support plate 3. The lead screw motor 18 is connected to a lead screw 19 and can drive the lead screw 19 to rotate. The top of the lead screw 19 is rotatably connected to a push plate bracket 17. A guide plate 20 is installed at the left end of the support plate 3. A threaded lifting hole 22 matching the lead screw 19 is formed on the right side of the lifting plate. The lead screw 19 passes through the threaded lifting hole 22. Left guide grooves 21 are respectively formed on the front and rear sides of the right side surface of the guide plate 20. Left sliders matching the left guide grooves 21 are respectively installed on the front and rear sides of the end of the lifting plate close to the guide plate 20. Right guide grooves 23 are respectively formed on the front and rear sides of the side surface of the push plate bracket 17 close to the lifting plate. Right sliders matching the right guide grooves 23 are respectively installed on the front and rear sides of the end of the lifting plate close to the push plate bracket 17. By providing the left guide grooves 21, left sliders, right guide grooves 23 and right sliders, the lifting seat 4 can only move up and down and cannot rotate. When the lead screw 19 rotates driven by the lead screw motor 18, it will drive the lifting seat 4 to lift through the threaded lifting hole 22 on the lifting seat 4, and then drive the corrugated cardboard tray on the lifting seat 4 to rise. The lead screw motor 18 is a servo motor. We can set that the lead screw motor 18 drives the lifting seat 4 to rise a certain height each time, so that the corrugated cardboard on the corrugated cardboard tray is higher than the fixed height of the pull-out plate 7 each time. Legs 24 are installed at the bottom of the lifting seat 4. By installing the legs 24 and when the lifting seat 4 descends to the lowest point, the legs 24 will contact the support plate 3, so that the legs 24 can play a good supporting role for the lifting seat.

[0026] A push plate 10 is installed on the piston rod of the push plate cylinder 6. The push plate cylinder 6 is fixedly installed on the push plate bracket 17. The push plate cylinder 6 is used to push the corrugated cardboard higher than the pull-out plate 7 towards the pull-out plate 7. The height of the bottom surface of the push plate 10 is higher than the top surface of the pull-out plate 7. The height difference between the bottom surface of the push plate 10 and the top surface of the pull-out plate 7 should be at least the thickness of one corrugated cardboard. By making the height of the bottom surface of the push plate 10 higher than the top surface of the pull-out plate 7, the present invention can well avoid the corrugated cardboard from contacting the end face of the pull-out plate 7 and being damaged by extrusion when the push plate 10 pushes the corrugated cardboard towards the pull-out plate 7.

[0027] The pull-out cylinder 5 is used to carry the corrugated cardboard pushed out by the push plate cylinder 6, so that the corrugated cardboard can be well stacked on the conveyor 2 and stacked between the left vertical plate 8 and the right vertical plate 9.

[0028] The drawing board cylinder 5 and the pushing board cylinder 6 are respectively arranged on the left and right sides of the moving cart 1 and are oppositely arranged. A drawing and pulling board 7 is installed on the piston rod of the drawing board cylinder 5. In the present utility model, the drawing board cylinder 5 drives the drawing and pulling board 7 to move left and right. The drawing board cylinder 5 is fixedly installed on the drawing board bracket 14, and the drawing board bracket 14 is fixedly installed on the frame of the conveyor 2. The drawing board bracket 14 includes two side guide beams 15. Chutes 16 are respectively opened on the two opposite inner side surfaces of the two side guide beams 15. The two sides of the drawing and pulling board 7 are respectively inserted into the chutes 16 of the two side guide beams 15. By arranging the two side chutes 16 and inserting the two sides of the drawing and pulling board 7 into the two side chutes 16, the two side chutes 16 not only play a guiding role for the drawing and pulling board 7, but also play a good supporting role for the drawing and pulling board 7, making the drawing and pulling board 7 work more stably.

[0029] On the upper side of the conveyor 2, on the left and right sides at one end close to the moving cart 1, a left vertical plate 8 and a right vertical plate 9 are respectively provided. The left vertical plate 8 is fixedly connected to the two side guide beams 15 respectively, and the right vertical plate 9 is fixedly installed on the frame of the conveyor 2. In the present utility model, the left vertical plate 8 and the right vertical plate 9 are conventional designs of a loading machine in the prior art. The bottom surface of the left vertical plate 8 is higher than the conveyor 2 by a certain height, which can make the corrugated board on the lower side of the stacked corrugated boards on the conveyor 2 gradually move towards the printing machine along with the conveyor 2. The right vertical plate 9 can play a limiting role for the stacked corrugated boards on the conveyor 2.

[0030] An upper baffle 12 is provided on the upper side of the drawing and pulling board 7. The distance from the bottom surface of the upper baffle 12 to the top surface of the drawing and pulling board 7 should be less than the thickness of a corrugated board. The upper baffle 12 is between the pushing board cylinder 6 and the drawing board cylinder 5, and the upper baffle 12 is on the right side of the upper vertical plate. Side baffles 13 are respectively provided on the two sides of the upper baffle 12. The upper baffle 12 and the two side baffles 13 form a U-shaped structure. The upper baffle 12 and the two side baffles 13 are both fixedly installed on the top of the drawing board bracket 14.

[0031] A distance sensor 11 is provided on the upper side of the lifting plate. The distance sensor 11 is mounted on the push plate bracket 17 through a bracket. The distance sensor 11 is directly above the lifting seat 4 and can detect the height of the corrugated board on the lifting seat 4. When a pallet is placed on the lifting seat 4, the distance sensor 11 detects the height of the corrugated board on the pallet. When the distance sensor 11 detects that the height of the corrugated board is greater than the threshold value, the lifting seat 4 drives the pallet to rise until the distance sensor 11 detects that the height of the corrugated board reaches the threshold value, and then the lifting seat 4 stops rising. At this time, the push plate cylinder 6 is activated, and the push plate 10 pushes the upper corrugated board towards the pull-out plate 7. When the piston rod on the push plate cylinder 6 extends to a certain length, the pull-out plate cylinder 5 is activated and drives the pull-out plate to move to the left. During the movement of the pull-out plate to the left, the upper baffle 12 will limit the corrugated board on the pull-out plate 7. When the pull-out plate 7 moves to the left of the upper baffle 12, the corrugated board on the pull-out plate 7 will fall down onto the conveyor 2.
