DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0022] like Figures 1 to 4 As shown, a paper feeding device for a paper cup forming machine of the present embodiment comprises a frame 1, a mounting plate 2 is arranged on the top of the frame 1, a receiving plate 3 is arranged above the mounting plate 2 through a supporting column, a blanking hole 31 in the shape of a shaped paperboard is arranged in the middle of the receiving plate 3, a plurality of receiving rods 32 which are arranged around the blanking hole 31 are arranged in the blanking hole 31, and a convex ring 321 which prevents a pile of paperboards from falling is arranged at the bottom end of the receiving rod 32; a suction cup hole 21 and a push rod groove 22 are arranged in the mounting plate 2, a suction cup mechanism 4 which can be raised and lowered to suck the bottom layer of paperboards from the paper pile is arranged in the suction cup hole 21, and a push rod mechanism 5 which pushes out the paperboards which fall onto the mounting plate 2 is arranged in the push rod groove 22; and a limiting mechanism 6 which presses the paperboards against the mounting plate 2 is arranged on the receiving plate 2.

[0023] This embodiment is mainly used for continuous feeding of single paperboards when forming noodle barrel paper cups, so as to realize automatic production. During operation, dozens or hundreds of stacked cut paperboards are placed between several receiving rods 32. In this embodiment, 8 receiving rods 32 are used, and the distances from each to the edge of the blanking hole 31 are equal, so that the shape of the city surrounded by the 8 receiving rods 32 is the same as the blanking hole 31; in order to adapt to the size specifications of different paperboards, the receiving plate 3 is fixed with an adjustment plate 33 with long holes by screws, and the receiving rod 32 is vertically fixed to the front end of the adjustment plate 33. The diameter of the convex ring 321 is larger than that of the receiving rod 32, so that the paperboard can be held from the bottom, so that the paperboard pile is suspended above the mounting plate 2. In order to hold the paperboard pile and facilitate the absorption of the bottom layer of paperboard, the outer diameter of the convex ring 321 is 2 to 5 mm larger than the diameter of the receiving rod 32.

[0024] In this embodiment, the mounting plate 2 is provided with four suction cup holes 21 and two push rod grooves 22 that penetrate through its thickness. The four suction cup holes 21 and the two push rod grooves 22 are symmetrical about the symmetry plane of the blanking hole 31; the suction cup hole 21 is a circular hole, and the push rod groove 22 is a long hole along the width direction of the blanking hole 31.

[0025] The suction cup mechanism 4 includes four gas rods 41, the bottom ends of the four gas rods 41 are connected to air pipes 43, the top ends of each gas rod 41 are respectively provided with a suction cup 42, the four gas rods 41 are respectively fixed to the lifting plate 44 through extension plates, and the frame 1 is provided with a lifting cylinder 45 for driving the lifting plate 44 to rise and fall. The air pipe 43 adopts a soft rubber tube, so that it can adapt to the lifting and falling of the gas rod 41.

[0026] The push rod mechanism 5 includes two guide rails 51 fixed to the lower side of the mounting plate 2, the guide rails 51 are slidably connected with a slider 52, a beam plate 53 is fixed between the two sliders 52, the beam plate 53 is fixed with two suspension plates 54, the suspension plate 54 is fixed with a push rod 55 protruding from the push rod slot 22 to the upper surface of the mounting plate 2; one end of the beam plate 53 is hinged with a connecting rod 56, the other end of the connecting rod 56 is hinged with a swing rod 57, the middle part of the swing rod 57 is hinged with the frame 1, the frame 1 is provided with a push cylinder 58, the piston rod end of the push cylinder 58 is hinged with the other end of the swing rod 57. The cross section of the push rod 55 is rectangular, and its upper end protrudes 10 to 30 mm from the upper surface of the mounting plate 2. The push rod 55 is fixed to the front end of the suspension part of the suspension plate 54, so as to avoid interference with the suction cup mechanism 4 when moving horizontally. In order to adapt to the moving stroke of the push rod 55 required for different cardboard widths, the connecting rod 56 can be adjusted in length and consists of two half rods connected by threads. The threaded connection is achieved by nuts, and both ends of the connecting rod 56 are ball joints.

[0027] During operation, the push rod mechanism 5 pushes the push rod 55 forward to cross the width of the cardboard. The specific working principle is that the push cylinder 58 retracts to make the upper end of the swing rod 57 swing forward, thereby pulling the slider 52 to move, and then driving the push rod 55 forward through the beam plate 53. Then the suction cup mechanism 4 controls the suction cup 42 to suck the bottom cardboard of the cardboard pile down. The specific working principle is that the lifting cylinder 45 pushes up to make the air rod 41 rise, and at the same time the air pipe 43 is evacuated to a negative pressure state. When the suction cup 42 is attached to the bottom cardboard of the cardboard pile, the negative pressure suction cup 42 absorbs the cardboard. When the lifting cylinder 45 controls the air rod 41 to descend, the absorbed cardboard is sucked down. At this time, the air pipe 43 is inflated to normal pressure, so that the sucked cardboard is separated from the suction of the suction cup 42. In the third step, the push cylinder 58 extends to make the upper end of the swing rod 57 swing backward, thereby controlling the push rod 55 to pull backward, and then the push rod 55 pushes the fallen cardboard to slide backward along the upper surface of the mounting plate 2.

[0028] In order to make the cardboard slide against the upper surface of the mounting plate 2, the receiving plate 3 is provided with a limiting mechanism 6 for pressing the cardboard against the mounting plate 2; the limiting mechanism 6 includes a chain plate 61 arranged in the middle and hanging rods 62 on both sides, the chain plate 61 is composed of a plurality of chains whose main bodies are vertically placed on the mounting plate 2 and whose upper ends are fixed to the receiving plate 3, the hanging rod 62 is a horizontal rod fixed to the receiving plate 3, and the gap between the hanging rod 62 and the mounting plate 2 is 1 to 2 times the thickness of the cardboard.

[0029] Furthermore, in order to prevent the cardboard from deflecting when sliding along the upper surface of the mounting plate 2, a limiting plate 7 is provided on each side of the cardboard on the upper surface of the mounting plate 2, and the distance between the two limiting plates 7 is adjustable.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
