[0026] Please refer to Figures 1 to 5 This application provides a cardboard feeding device, including a feeding rack 1 and a receiving component. The feeding rack 1 has an inlet 11 and an outlet 12 on opposite sides. The receiving component is located at the inlet end of the feeding rack 1 to receive the incoming cardboard stacks and feed them into the feeding rack 1. The receiving component includes a rotary table 2 and a conveyor line 3. The rotary table 2 is equipped with a lifting mechanism 4. The conveyor line 3 is connected to the lifting mechanism 4 so that the height of the conveyor line 3 relative to the rotary table 2 is variable. The outlet end of the feeding rack 1 is connected to the equipment feeding line. The feeding rack 1 is equipped with a feeding wheel 13, which is used to contact the top of the cardboard stack and can feed the cardboard on the surface of the cardboard stack from the outlet 12 of the feeding rack 1 into the equipment feeding line by rotation.

[0027] The feeding rack 1 in this application can adopt a box structure with an inlet and an outlet on opposite sides of the box. Alternatively, it can be directly assembled from multiple panels. A receiving component can receive the incoming paper stacks and feed them into the feeding rack 1 through the inlet. The outlet end of the feeding rack 1 is connected to the equipment's feeding line. A feeding wheel 13 is installed inside the feeding rack 1. This feeding wheel 13 contacts the top of the paper stack, and its rotation feeds the cardboard surface of the paper stack from the outlet of the feeding rack 1 into the equipment's feeding line, achieving flattening of the cardboard on the feeding line. This device enables automatic feeding during production, reducing manual intervention and improving production efficiency.

[0028] In this application, the receiving component includes a rotary table 2 and a conveyor line 3. The rotary table 2 is equipped with a lifting mechanism 4, and the conveyor line 3 is connected to the lifting mechanism 4. The horizontal rotation of the rotary table 2 can change the orientation of the conveyor line 3, thereby facilitating the reception of paper stacks flowing from any direction. At the same time, the action of the lifting mechanism 4 can change the height of the conveyor line 3 relative to the rotary table 2, thereby facilitating the reception of paper stacks flowing from different heights, making the device more practical and more convenient for receiving paper stacks.

[0029] It should be noted that the aforementioned rotary table 2 can be installed on the ground, or it can be installed in a pit to further reduce its height above the ground. The aforementioned rotary table 2 can be a hydraulic rotary table 2, or it can adopt other structures to drive rotation, such as using a gear-driven turntable for rotation.

[0030] According to some embodiments of this application, the feeding rack 1 is provided with a support plate 14, a guide rod 15 and a driving member 16. The support plate 14 is arranged horizontally, the guide rod 15 is arranged vertically and is slidably connected to the support plate 14. The driving member 16 is located at the bottom of the feeding rack 1 and is used to drive the support plate 14 to slide up and down along the guide rod 15.

[0031] In this application, the guide rods 15 can be provided in two or four positions. The support plate 14 has through holes at positions corresponding to the guide rods 15, and a guide sleeve 17 is fixedly installed on the lower side of the support plate 14, with the guide sleeve 17 opposite to the through holes. The aforementioned driving component 16 can be a servo cylinder, located below the support plate 14, and its height can be changed by the extension and retraction of the piston rod.

[0032] It should be noted that, since the cardboard has a certain thickness, when the feeding wheel 13 rotates and sends out the cardboard on the surface of the paper stack, a certain distance will be formed between the top of the paper stack and the feeding wheel 13. Therefore, the driving component 16 needs to move to push the support plate 14 upward to a certain height so that the top of the paper stack can re-contact the feeding wheel 13.

[0033] In this application, the receiving component can receive the paper stacks that have been transferred and feed them into the support plate 14 inside the feeding rack 1. The support plate 14 can slide up and down along the guide rod 15 with the cooperation of the guide rod 15 and the drive component 16. The feeding wheel 13 provided inside the feeding rack 1 contacts the top of the paper stack by rotating the feeding wheel 13, thereby feeding the cardboard on the surface of the paper stack into the equipment feeding line from the outlet of the feeding rack 1, and realizing the flat laying of the cardboard on the equipment feeding line.

[0034] According to some embodiments of this application, the feeding wheel 13 is close to the outlet end of the feeding frame 1, the axis of the feeding wheel 13 is parallel to the support plate 14, and both ends of the feeding wheel 13 are rotatably connected to the feeding frame 1. The feeding frame 1 is provided with a first drive motor 18, and the first drive motor 18 drives the feeding wheel 13 to rotate through the belt transmission structure 181 to realize material discharge.

[0035] The aforementioned feeding roller 13 is located near the outlet end of the feeding rack 1, facilitating the ejection of cardboard from the outlet. Since the cardboard stack is placed on the support plate 14, the axis of the feeding roller 13 is parallel to the support plate 14, allowing for better contact between the lower side of the feeding roller 13 and the top of the cardboard stack. The aforementioned belt drive structure 181 typically includes a driving pulley, a driven pulley, and a drive belt. The driving pulley is connected to the output shaft of the first drive motor 18, and the driven pulley is connected to the axle at one end of the feeding roller 13, using the drive belt to rotate the feeding roller 13.

[0036] According to some embodiments of this application, the support plate 14 is provided with limiting strips 141. There are two limiting strips 141 arranged along the inlet to outlet direction of the feeding rack 1. The interval between the two limiting strips 141 is adapted to the outer dimensions of the paper stack entering the feeding rack 1.

[0037] After the conveyor line 3 on the receiving component rotates to the same direction as the limiting strip 141, the receiving paper stack can be sent into the loading rack 1 by the action of the conveyor line 3. During this process, the two limiting strips 141 are located on both sides of the paper stack, which can play a certain limiting and guiding role to prevent excessive deviation during the movement of the paper stack.

[0038] According to some embodiments of this application, the support plate 14 is provided with a plurality of ball bearings 142, which are arranged in an array near the inlet of the loading rack 1. By providing ball bearings 142 on the support plate 14 near the inlet of the loading rack 1, the ball bearings 142 can roll freely when the paper stack is transferred from the conveyor line 3 on the receiving component to the support plate 14, reducing friction and making it easier for the paper stack to enter the support plate 14. It should be noted that the ball bearings 142 are only slightly higher than the upper surface of the support plate 14.

[0039] According to some embodiments of this application, the feeding rack 1 is provided with vertical grooves 19 on both sides opposite to the two ends of the feeding wheel 13. Rectangular sliders 191 are provided in the grooves 19. The wheel axles at both ends of the feeding wheel 13 are rotatably connected to the two sliders 191 through bearings 192. The position of the sliders 191 in the grooves 19 can be adjusted up and down.

[0040] According to some embodiments of this application, the slider 191 is provided with a fixing ear 1911, the fixing ear 1911 is provided with a fixing hole, and the feeding rack 1 is provided with a plurality of threaded holes 193 along the vertical edge. The fixing ear 1911 is fixedly connected to the feeding rack 1 by a bolt 194 passing through the fixing hole and any threaded hole 193.

[0041] In this application, a vertical chute 19 is provided in the feeding rack 1, and a rectangular slider 191 is provided in the chute 19. The axles at both ends of the feeding wheel 13 are rotatably connected to the slider 191 through bearings 192. Moreover, the slider 191 is connected to different threaded holes 193 through its fixing ears 1911, so that the position of the slider 191 in the chute 19 can be adjusted up and down. This makes the height position of the feeding wheel 13 on the feeding rack 1 adjustable. This design allows the paperboard to be discharged to adapt to the feeding line of equipment of different heights, further improving the practicality of the device.

[0042] According to some embodiments of this application, the lifting mechanism 4 includes a column 41 and a telescopic member 42. There are two columns 41 and their lower ends are fixedly connected to the rotary table 2. The column 41 is provided with a guide rail groove 411 along its vertical edge. The conveyor line 3 includes a frame 31 and a plurality of transmission rollers 32. Two guide rail blocks 311 are fixedly provided on the frame 31. The guide rail blocks 311 are slidably engaged in the guide rail groove 411. The telescopic member 42 is used to drive the frame 31 to move up and down.

[0043] According to some embodiments of this application, a connecting plate 312 is fixedly connected to the frame 31, a top plate 43 is connected between the top ends of the two columns 41, the telescopic member 42 is installed on the top plate 43, and the output end of the telescopic member 42 is connected to the connecting plate 312.

[0044] The aforementioned telescopic component 42 can be a cylinder. The piston rod of the cylinder is connected to the connecting plate 312. The piston rod, which moves with telescopic motion, acts on the frame 31 through the connecting plate 312, causing the guide block 311 to slide up and down along the guide groove 411, thereby driving the conveyor line 3 to move up and down, so as to change the height of the conveyor line 3 relative to the rotary table 2, thus facilitating the reception of paper stacks flowing from different heights.

[0045] According to some embodiments of this application, a second drive motor 33 is provided on the frame 31, and the second drive motor 33 drives multiple transmission rollers 32 to rotate synchronously through a chain transmission structure 34.

[0046] The aforementioned chain drive structure 34 typically includes a drive sprocket, a driven sprocket, and a chain. The drive sprocket is connected to the output shaft of the second drive motor 33, and the driven sprockets are connected to the axles at one end of multiple drive rollers 32. The chain drives the multiple drive rollers 32 to rotate synchronously, thereby realizing the transfer of paper stacks.
