The position and number of the indentations can be adjusted by adjusting the pressing wheel. The indentation roller 402 is provided with a lifting cylinder 19 for adjusting the spacing by a rotating connection.

[0049] Since the carton board is basically made of corrugated paper, and the surface of corrugated paper is rough, and the corrugated paper is also thin and is stored in stacks, the stability of ordinary fixed and vacuum suction structures is poor and difficult to apply, so structural improvements are carried out.

[0050] like Figures 4 to 9, both sides of the control shell 10 are provided with a paper box plate structure 11, which includes a plurality of pin heads 111 with flexible tips, which can be inserted into the wave gap of the corrugated core paper in the middle of the paper box board and feed it. The control shell 10 is connected to connecting rods 123 passing through the rotating shell 9 at both ends close to the side plate 6. The rotating shell 9 is provided with a rotating paper box plate structure 12 for maintaining horizontal rotation and feeding the paper box plate. The top of the control shell 10 is provided with a paper box plate tensioner for pressing the paper box plate structure 11. Structure 13, two ventilation hoses 14 are arranged on the carton board loosening structure 13, and round shells 15 are installed at the end positions of the two ventilation hoses 14. Two air drive mechanisms 16 for loosening the carton board are arranged on the round shells 15. A rotary column 17 is arranged inside the round shells 15. The rotation of the rotary column 17 can push the air drive mechanism 16 for loosening the carton board to make the pin head 111 vibrate to feed the carton board. Two restraint rings 171 are connected to the outer periphery of the rotary column 17 for restraining the air drive mechanism 16 for loosening the carton board in a non-vibrating state.

[0051] like Figures 5 to 7 As shown, the paper grabbing box plate structure 11 also includes a plurality of connecting seats 112 bolted to the pin heads 111, one side of the plurality of connecting seats 112 is threadedly connected with an adjusting screw 113, one end of the plurality of adjusting screws 113 is connected with a connecting frame 114, one side of the connecting frame 114 is connected with a cross plate 115 the cross plate 115 is connected with a force-bearing plate 116 extending into the interior of the control shell 10 and rotatably connected to the control shell 10, one end of the force-bearing plate 116 is an arc surface for facilitating force bearing, the bolt fixation of the pin head 111 to the connecting seat 112 and the thread fixation of the adjusting screw 113 can further realize the tilt adjustment of the angle of the pin head 111 and the adjustment of the spacing so as to adapt to paper box boards of different sizes.

[0052] like Figure 3 , Figure 5 and Figure 6 As shown, the carton board tensioning structure 13 includes a first pneumatic shell 131 fixed to the top of the control shell 10, a first air plug 132 is arranged inside the first pneumatic shell 131, a connecting rod 133 is installed at the bottom center of the first air plug 132, and the bottom end of the connecting rod 133 is connected to a pressure plate 134 in contact with the force-bearing plate 116, and the pressure plate 134 is an I-shaped structure, and both sides of the pressure plate 134 can contact both sides of the arc end of the force-bearing plate 116, and the contact points are the upper and lower surfaces, thereby also having a certain limiting effect.

[0053] like Figure 3 , Figure 8 and Fig. 9As shown, the air drive mechanism 16 for the loose paper box plate includes a second pneumatic shell 161, a second air plug 162 is arranged inside the second pneumatic shell 161, a spring 163 is arranged on one side of the second air plug 162, the spring 163 has a force to move in the direction of the circular shell 15, so that the second air plug 162 will not move when it is not subjected to force, an extension rod 164 is integrally formed on the other side of the second air plug 162, a curved arc plate 165 with a sloped surface on one side is installed at the end of the extension rod 164, a dial head 173 is connected to the outer periphery of the swivel column 17, the second pneumatic shell 161, the first pneumatic shell 131 and the ventilation hose 14 are filled with gas, a barometer is arranged on the outer side of the first pneumatic shell 131 to facilitate the detection of internal gas, and a gas inlet for inputting gas is provided on the second pneumatic shell 161 or the first pneumatic shell 131.

[0054] It should be noted that the positions of the two curved plates 165 need to correspond to the grabbing position and the position of putting down the carton board, that is, the pin head 111 can move to grab and put down the carton board at the grabbing position and the position of putting down the carton board.

[0055] like Figure 4 As shown, the rotary paper feeding box plate structure 12 includes two meshing gears 121 and an intermediate gear 122 that mesh with each other. The two meshing gears 121 have the same diameter and number of teeth. One of the meshing gears 121 is fixed to the side plate 6, and the other meshing gear 121 and the intermediate gear 122 are rotatably connected to the inside of the rotating shell 9, and the center of the other meshing gear 121 is connected to the outer periphery of the connecting rod 123. The two meshing gears 121 with the same number of teeth and diameter and the intermediate gear 122 therebetween cooperate, and one of the meshing gears 121 and the side plate 6 is fixed and non-rotating. Therefore, when the other meshing gear 121 rotates following the center rod 7, the intermediate gear 122 will be rotated along the edge by the fixed meshing gear 121, and the angle of inclination of the rotatable meshing gear 121 following the rotation will be offset, that is, the connecting rod 123 and the control shell 10 will always remain in a horizontal state during the rotation and movement, thereby ensuring that the paper box plate will not tilt during the feeding process and stability is guaranteed.

[0056] Further, such as Fig. 9 As shown, an external plate 18 is installed on the side of the bending plate 165, and a ring body 172 is connected to the outer edge of the constraint ring 171. The ring body 172 has a notch. The constraint ring 171 and the ring body 172 are arranged around the rotating column 17 and pass through the external plate 18. The external plate 18 is constrained in the surrounding trajectory of the ring body 172. The notch position is the area space required for squeezing the bending plate 165. The advantage of this design is that when it is not in an extrusion state, the ring body 172 will constrain the external plate 18, so that the second air plug 162 will not move, thereby avoiding the spring 163 from shaking when the equipment vibrates during operation.

[0057] Working principle: the driving motor 8 is controlled by the external control structure to drive the center rod 7 to rotate and rotate to the grabbing area. During the rotation of the center rod 7, the dial head 173 on the outer periphery of the rotary column 17 is driven to rotate. When it moves to the grabbing area, it can squeeze the curved plate 165, so that the gas squeezed from the second air pressure shell 161 is transferred to the first air pressure shell 131, and the gas pushes the pressing plate 134 downward to tilt the connecting frame 114. At this moment, the driving motor 8 is reversed by the control structure, so that the pressing plate 134 quickly recovers to realize the vibration and swing of the pin head 111, and the corrugated core paper of the carton board is inserted at the moment of the vibration and swing. The wave gap, and the tip of the pin head 111 is made of soft material. When the pin head 111 is in the paper layer in the middle of the adjacent wave gap, it will be bent and then inserted to avoid damage to it. After fixing, the driving motor 8 continues to drive the center rod 7 to rotate in the reverse direction, so that the rotating shell 9 rotates, so that the connecting rod 123 rotates to the position of the paper feeding box plate assembly 3. When it reaches the claw release area, it will contact the curved arc plate 165 on the other side, and the above-mentioned vibration swing will be generated again, so that the pin head 111 is separated from the paper box board at the moment, and the paper box board falls onto the paper feeding box plate assembly 3, and it can be transported. Such reciprocating rotation can be carried out for continuous fixed-point feeding;

[0058] It should be noted that, since the above-mentioned fixed-point reciprocating stepping feeding is carried out, a paper box board lifting unit 5 is provided at the input end of the carton board processing frame 1, and the paper box board lifting unit 5 includes a lift 501 and a lifting platform 502. The driving end of the lift 501 is fixed to the lifting platform 502, and the paper box board lifting unit 5 is used to store carton boards. When grabbing a carton board, the lift 501 controls the lifting platform 502 to rise through an external control structure, so that the next carton board moves to the grabbing position.

[0059] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
