[0021] Preparation: the operator can manually stack multiple bottom paperboard 10 on elevating platform 5, in order to facilitate operator feeding, the initial state of elevating platform 5 is located at the lowermost of frame 1. Then, feeding elevating system 4 runs, drives elevating platform 5 and the bottom paperboard 10 on elevating platform 5 to rise to the set height and stop running, then, feeding conveying mechanism 2 drives suction mechanism 3 located above bottom paperboard 10 to adsorb the bottom paperboard 10 stacked on the uppermost layer, and drives suction mechanism 3 and bottom paperboard 10 to move along the direction of X axle (i.e. downstream direction), to provide bottom paperboard 10 for the next bottom paperboard edge forming process.

[0022] In some embodiments, the feeding conveying mechanism 2 includes X axle helical rack 21 extending along the direction of X axle and being arranged on the frame 1, conveying gear 22 meshing with the X axle helical rack 21, conveying motor 23 fixedly connected with the center of the conveying gear 22, and conveying frame fixedly connected with the conveying motor 23; the conveying frame is provided with transverse beam 25 extending along the direction of X axle, and the suction mechanism 3 is fixedly connected with the transverse beam 25. Specifically, when the conveying motor 23 rotates, it will drive the conveying gear 22 to rotate synchronously, so that the conveying frame connected with the conveying motor 23 can move synchronously along the direction of X axle. Since the conveying frame is fixedly connected with the transverse beam 25, and the suction mechanism 3 is arranged on the transverse beam 25, the suction mechanism 3 and the bottom paperboard on the suction mechanism 3 can be driven synchronously along the direction of X axle. When the bottom paperboard feeding is completed, the conveying motor 23 is reversely rotated to reset the whole feeding conveying mechanism 2.

[0023] In some embodiments, the conveying frame comprises an upper frame body 241, a lower frame body 242, and a middle partition plate 243, the upper frame body 241 and the lower frame body 242 are arranged in a top-to-bottom manner, and the middle partition plate 243 is located between the upper frame body 241 and the lower frame body 242; a guide rod 244 is arranged between the upper frame body 241 and the lower frame body 242, both ends of the guide rod 244 are fixedly connected with the upper frame body 241 and the lower frame body 242 respectively; a guide cylinder 245 is further sleeved in the guide rod 244, and the guide cylinder 245 is fixedly connected with the middle partition plate 243; a conveying cylinder 26 with an output end downward is further arranged on the upper frame body 241, and the output end of the conveying cylinder 26 is fixedly connected with the middle partition plate 243; the transverse moving beam 25 is arranged on the middle partition plate 243. Specifically, when the lifting platform 5 rises to a set position and stops running, that is, the base paper rises to a set position and stops rising, the output end of the conveying cylinder 26 extends downward, drives the middle partition plate 243 to move downward synchronously under the guidance of the guide rod 244, and drives the transverse moving beam 25 fixedly connected with the middle partition plate 243 and the suction mechanism 3 to move downward synchronously, so that the suction mechanism 3 can fully contact with the upper surface of the base paper, and the suction of the base paper is ensured.

[0024] In some embodiments, the transverse moving beam 25 is arranged in two, the two transverse moving beams 25 are symmetrically arranged along the X-axis direction, and the suction mechanism 3 is arranged on each of the two transverse moving beams 25, the suction mechanism 3 arranged on each of the two transverse moving beams 25 is arranged in multiple along the X-axis direction, and the suction mechanism 3 is a vacuum suction disc. In this embodiment, the base paper is rectangular, the long side extends along the X-axis direction, and the short side extends along the Y-axis direction, the two transverse moving beams 25 are located above the base paper, and the multiple vacuum suction discs on the two transverse moving beams 25 are used to suck the base paper, so as to ensure the suction effect. Specifically, the transverse moving beam 25 can move along the Y-axis direction, so as to adjust the position of the suction mechanism 3 arranged thereon relative to the base paper 10, that is, the suction mechanism 3 can feed the base paper 10 with different lengths of the short side.

The cooperation of the X-axis guide rail 11 and the X-axis sliding block 12 enables the conveying frame to move stably along the X-axis direction of the rack 1, and can avoid the base paper on the suction mechanism 3 from vibrating.

[0026] In some embodiments, the rack 1 is provided with a conveying frame start approaching switch 16 extending along the X-axis direction and a conveying frame to position sensor 17, and the distance between the conveying frame start approaching switch 16 and the conveying frame to position sensor 17 is the moving stroke of the conveying frame.

Specifically, the lifting platform 5 and the plurality of stacked bottom paper boards are synchronously lifted, and after the position of the uppermost bottom paper board is captured by the bottom paper board in place sensor 15, the control mechanism drives the lifting motor 41 to stop running, and then the output end of the conveying cylinder 26 extends downward to drive the suction material mechanism 3 to move downward and adsorb the uppermost bottom paper board, and then the output end of the conveying cylinder 26 retracts upward to drive the suction material mechanism 3 and the bottom paper board to move upward and move in the direction of the X axis under the action of the feeding conveying mechanism 2.

By arranging two limit sensors, the moving stroke of the lifting platform 5 is limited, so as to ensure the moving accuracy of the lifting platform 5 and the bottom paper boards 10 stacked on the lifting platform 5 in the direction of the Z axis. Specifically, the positions of the upper limit sensor 18 and the lower limit sensor 19 and the bottom paper board in place sensor 15 relative to the chassis 1 can be adjusted, so that the operation of the bottom paper board feeding device is more accurate, and the bottom paper board feeding device can feed the bottom paper boards 10 of different thicknesses by adjusting the heights of the sensors relative to the chassis 1.
