The return spring 19 is an extension spring, and the return spring 19 has pretension; it is ensured that the reset spring 19 has a certain pressure on the carton piece by the licking roller 14 when the licking roller 14 drives the carton piece to move outwards, as shown in b in fig. 21, even though the last carton piece, the licking roller 14 needs to have a certain pulling force, so that the licking roller 14 applies a certain pressure on the last carton piece.

As shown in fig. 3 and 7, one ends of the two guiding expansion plates 5 are symmetrically mounted at two ends of the connecting rod 26 in a hinged manner, and the other ends of the two guiding expansion plates 5 are respectively mounted at one end of two square grooves 42 opened on the bottom plate 13 in a one-to-one correspondence manner in a hinged manner.

As shown in fig. 1 and 2, the first synchronizing wheel 9 is mounted on the output shaft of the speed reducing motor 1, the second synchronizing wheel 11 is mounted at one end of the first fixed rotating shaft 28, which is located outside the corresponding arc-shaped guide rail 8, and the first synchronizing wheel 9 and the second synchronizing wheel 11 are connected through the first synchronizing belt 10.

The diameter of the second gear 37 is 3 times the diameter of the first gear 35; after the rack 36 meshed with the first gear 35 moves upwards for a certain distance, the arc-shaped rack 27 meshed with the second gear 37 moves downwards for 3 times of the distance of the rack 36 moving upwards, the licking roller 14 can only need a small deformation amount when moving downwards each time through the rotation of the first gear 35 and the second gear 37, the ratio of the deformation amount caused by the rotation of the first gear 35 and the second gear 37 to the previous compression amount is set to be small through setting a certain compression amount in the previous period, the pressure change caused by the small deformation amount is small, namely, when the licking roller 14 drives the paper box plate to move, the pressure change of the licking roller 14 exerted by the return spring 19 to the paper box plate is relatively small, the pressure of the licking roller 14 to the paper box plate each time is relatively stable, and a small pressure is kept, and only one paper box plate can be driven to move outwards through friction each time through the pressure, the phenomenon that the normal movement of the carton piece is influenced because the carton piece moved outwards by the licking roller 14 driven by friction becomes more because the pressure of the licking roller 14 on the carton piece is overlarge is avoided; the pressure of the licking roller 14 on the carton piece is enough to drive the carton piece to move, but the carton piece is not pressed to be dead.

The specific working process is as follows: when the pushing device designed by the invention is used, before the pushing device is used, the paper box sheet is firstly placed in the paper storage shell 2, and when the pushing device is placed, the licking roller 14 is firstly manually lifted, and the paper box sheet is placed on the lower side of the licking roller 14, so that the licking roller 14 is pressed on the upper side of the uppermost paper box sheet; after the carton sheets are installed, pushing the rear ends of the carton sheets to enable the front ends of the other carton sheets except the uppermost carton sheet to be propped against the paper blocking plate 7; then controlling the gear motor 1 to work, wherein the gear motor 1 drives the first synchronous wheel 9 to rotate, the first synchronous wheel 9 drives the second synchronous wheel 11 to rotate through the first synchronous belt 10, the second synchronous wheel 11 drives the first fixed rotating shaft 28 to rotate, the first fixed rotating shaft 28 drives the licking roller 14 mounted on the first synchronous wheel to rotate, as shown in a in fig. 21, the licking roller 14 rotates to drive one paper box sheet located on the lower side of the licking roller to move through friction, so that the paper box sheet moves outwards beyond the upper side of the paper blocking plate 7, and after the front end of the paper box sheet is contacted with the guide plate 6 in the moving process, the front end of the paper box sheet bends downwards and moves onto the guide expansion plate 5 under the extrusion and guide effects of the guide plate 6; the front end of the carton sheet can move to a conveying belt 15 in the discharging and conveying mechanism through the guiding action of the guiding expansion plate 5, and the front end of the carton sheet is positioned at the lower side of the paper pressing roller 3; the carton sheet is taken away by the conveying belt 15 along the conveying belt 15 through the guiding action of the paper pressing roller 3, and then is moved to the next forming station; when the rear end of the paper box sheet is separated from the licking roller 14, a gap is formed between the licking roller 14 and the uppermost side of the paper box sheet in the paper storage case 2, at this time, under the action of the two return springs 19, the two racks 36 move upwards to drive the two first gears 35 to rotate, the two first gears 35 rotate to drive the two first rotating shafts 34 to rotate, the two first rotating shafts 34 rotate to drive the two second gears 37 to rotate, the two second gears 37 rotate to drive the two arc-shaped racks 27 to move downwards, the two arc-shaped racks 27 move downwards to drive the two arc-shaped sliders 29 to move downwards, the two arc-shaped sliders 29 move downwards to drive the first fixed rotating shaft 28 to move downwards, the first fixed rotating shaft 28 moves downwards to drive the licking roller 14 to move downwards, so that the licking roller 14 is in contact with the paper box sheet positioned at the uppermost side in the paper storage case 2 in this state, meanwhile, the two arc-shaped sliding blocks 29 move downwards to drive the two connecting guide blocks 24 to move downwards, the two connecting guide blocks 24 move downwards to drive the three paper blocking plates 7 to move downwards, so that the front ends of the paper box sheets positioned at the uppermost side are separated by the upper sides of the three paper blocking plates 7, the two paper blocking plates 7 move downwards to drive the connecting rod 26 to move downwards, and the connecting rod 26 moves downwards to drive the upper ends of the two guide expansion plates 5 to move downwards so that the two guide expansion plates 5 retract; the two guide expansion plates 5 swing downwards to drive the guide plate 6 to swing downwards; ready for the next time.

In summary, the following steps:

compared with the traditional carton piece pushing device, the carton piece pushing device has the advantages that the carton pieces of the traditional carton piece pushing device are pushed out from the lower side of the paper storage shell 2, so that each time the carton pieces are pushed out, the gravity exerted by all the carton pieces on the upper side in an aligned mode is applied to the carton pieces, the resistance on the lowest carton piece is increased, the pushing outlet of the pushing device designed by the invention is located on the upper side of the paper storage shell 2, the pushed carton pieces cannot be influenced by other carton pieces during each pushing, and the pushing resistance is small. According to the carton sheet pushing device designed by the invention, through the transmission of the designed first gear 35, the second gear 37, the rack 36 and the arc-shaped rack 27, the reset spring 19 only needs a small deformation amount when the licking roller 14 moves downwards each time, namely, when the licking roller 14 drives the carton sheet to move each time, the pressure change of the reset spring 19 applied to the licking roller 14 to the carton sheet is relatively small, the pressure of the licking roller 14 to the carton sheet is relatively stable each time, and a small pressure is kept, through the pressure, the licking roller 14 can only drive one carton sheet to move outwards through friction each time, and the influence on the normal movement of the carton sheet caused by the fact that the pressure of the licking roller 14 to the carton sheet is too large and the number of carton sheets moved outwards through friction driving of the licking roller 14 is increased is avoided; as shown in fig. 22, in the carton sheet pushing device designed by the present invention, the designed paper blocking plate 14 is arc-shaped, if a vertical paper blocking plate is adopted as the first drawing in fig. 22, under the condition that the last paper carton sheet can be smoothly conveyed, under the same number of carton sheets, the included angle between the carton sheet located at the highest point and the conveying mechanism is relatively large, the distance between the carton sheet located at the highest point and the conveying mechanism is large, and the carton sheet is not easily conveyed onto the conveying mechanism; if the included angle between the paper box sheet at the highest point and the conveying mechanism is reduced, the storage amount of the paper box sheets in the paper storage shell is reduced; the adding times of the carton pieces are increased; according to the arc-shaped paper blocking plate designed by the invention, the distance between the foremost end of the paper box sheet positioned at the highest point and the conveying mechanism is increased, and under the condition that the same number of paper box sheets are used and the last paper box sheet can be conveyed smoothly, the included angle between the foremost end of the paper box sheet positioned at the highest point and the conveying mechanism is reduced, so that the paper box sheet is conveyed to the conveying mechanism more easily; in addition, the paper blocking plate is designed to be arc-shaped, so that the power of the speed reducing motor 1 can be better transmitted to the licking paper roll 7.
