The lower frame base 62 is hinged to the upper end of the roller base 53, and the lower frame driving member 63 is hinged to the lower frame driving member base 64. The blanking frame driver base 64 is mounted to the ground and is in the same horizontal plane as the blanking frame base 62.
Illustratively, when the swing angle of the blanking frame 61 is larger, the blanking frame driving member base 64 and the blanking frame base 62 can be arranged separately, so that the space is reasonably utilized, and when the swing angle of the blanking frame 61 is smaller, the blanking frame driving member base 64 and the blanking frame base 62 can be integrally arranged like the feeding base 32, so that the occupied area of the equipment is reduced, and the space utilization rate is improved.
Illustratively, when cutting large diameter roll paper, it takes time and effort to manually convey the roll paper, and further alternatively, the lower carriage driving member 63 is a hydraulic cylinder, the output end of the hydraulic cylinder is hinged with the upper end of the lower carriage 61, and the tail of the hydraulic cylinder is hinged with the lower carriage driving member base 64. Before pushing paper, the hydraulic cylinder is in a contracted state, the head of the blanking frame 61 faces the outer side of the conveying mechanism 5, when the second roller set 52 conveys the cut paper to the blanking end, the hydraulic cylinder stretches to drive the upper end of the blanking frame 61 to turn to the paper, the paper is pushed out, automatic blanking of the paper is achieved, and production efficiency is improved. In other embodiments, the driving member 63 may be a driving motor or a scissors telescopic mechanism to rotate the discharging frame 61.
In other embodiments, the blanking frame driver 63 may be an electric push rod or an air cylinder.
Illustratively, the upper end of the blanking frame 61 may be provided with a rotatable sleeve, which is in contact with the roll paper, and which is rotatable during blanking of the roll paper to reduce friction between the roll paper and the blanking frame 61 and effectively protect the peripheral side surface of the roll paper from being damaged.
Alternatively, as further shown in fig. 3, the feeding end of the conveying mechanism 5 is provided with a discharging mechanism 6, and a discharging frame 61 and a feeding mechanism 3 are symmetrically disposed on both sides of the conveying mechanism 5, the discharging frame 61 being for preventing roll paper loaded by the loading hopper 31 from falling from the discharging frame 61 side. The functional structure of the discharging mechanism 6 at the feeding end is the same as that of the discharging mechanism 6 at the discharging end, and the description is omitted here.
Specifically, when the feeding mechanism 3 lifts the roll paper to a position close to the feeding hopper 31, the feeding frame 61 falls back earlier than the feeding hopper 31 when the feeding mechanism 61 is in contact with the roll paper, the roll paper falls back along with the abutting feeding frame 61, and finally the roll paper is stably placed on the carrier roller 7, so that automatic feeding of the roll paper is realized, the feeding hopper 31 and the feeding frame 61 cooperate to place the roll paper, the roll paper is prevented from falling from one side of the feeding frame 61 in the feeding process, stable placement of the roll paper is realized, personnel safety is protected, and production efficiency is improved.
For easy understanding, the working principle and working process of the roll paper cutting device provided in this embodiment are as follows:
1) In the preparation stage, the paper ejection mechanism 1 is positioned at the extreme position of the tail end of the conveying mechanism 5, the head of the air expansion shaft 11 arranged on the paper ejection mechanism 4 is spaced from the feeding end of the conveying mechanism 5, collision with the air expansion shaft 11 during roll paper feeding is prevented, the air expansion shaft 11 is positioned at the extreme position of the lower end of the paper ejection frame 12, and the first roller set 51 and the second roller set 52 are respectively positioned below the carrier roller 7.
2) And in the feeding stage, the feeding mechanism 3 and the discharging mechanism 6 at the feeding end move cooperatively to put the roll paper on the feeding end of the conveying mechanism 5.
3) In the cutting stage, an air expansion shaft 11 assembled on a paper ejection mechanism 1 moves in the vertical direction according to the diameter of paper roll until the air expansion shaft 11 is aligned with the center position of a paper core hole of the paper roll, a linear driving mechanism 2 drives the air expansion shaft 11 to be inserted into the paper core of the paper roll, the air expansion shaft 11 ventilates and expands the paper core hole of the paper roll, a first roller group 51 lifts the paper roll to separate from a carrier roller 7, a control module controls the paper ejection mechanism 1 to move a corresponding distance according to the specific length of the required paper roll, then the first roller group 51 falls back below the carrier roller 7, a second dustproof door 42 is closed, a first dustproof door 41 moves downwards to a position with a certain gap from the peripheral side surface of the paper roll, the carrier roller 7 drives the paper roll to rotate, the paper roll starts to be cut in a rotating mode, the paper core hole of the paper roll drives the air expansion shaft 11 to rotate, and the paper ejection mechanism 1 with the air expansion shaft 11 restrains the movement of the paper core.
4) And in the discharging stage, after the cutting is finished, the second dustproof door 42 is opened, and the second roller set 52 conveys the cut part out of the paper cutting mechanism 4 and then is pushed out by the discharging mechanism 6 at the discharging end.
