The driving chain can work under the conditions of low speed, heavy load and raised dust, and is suitable for the production environment of paperboards. The first driving assembly adopts a driving chain, so that the accurate average transmission ratio can be ensured, and when the transmission power is larger, the force acting on a motor shaft and a bearing of the driving assembly is smaller, so that the height of the paper delivery table 200 can be accurately controlled.

Referring to fig. 1, 5 and 6, the delivery mechanism further includes a third driving assembly and a third slide rail 320, the third slide rail 320 is disposed along the height direction, and the third driving assembly is connected to the sub delivery member in a driving manner, so that the sub delivery member slides along the third slide rail 320 to be close to or far from the delivery table 200.

The holding section 312 is arranged outside the interval between the paper collecting component 100 and the paper collecting platform 200 and vertically extends along the height direction, when the movable curtain 300 slides to the holding section 312, the bottom of the fixed position covered by the movable curtain 300 is opened, the paper stack loses the support of the movable curtain 300, the paper stack falls onto the paper collecting platform 200, and the movable curtain 300 can be vertically arranged along the height direction at the moment, so that the space is saved, and the space utilization rate of the paper collecting mechanism is improved and is more compact.

Referring to fig. 7 and 8, the first alignment assembly includes: the paper feeding mechanism comprises a first guide rod 110, a front baffle 111, a rear baffle 112 and a fourth driving assembly, wherein the first guide rod 110 extends along the paper feeding direction of the paper feeding mechanism, the front baffle 111 is connected with the first guide rod 110 in a sliding mode, and the fourth driving assembly is connected with the front baffle 111 in a driving mode so that the front baffle 111 is close to or far away from the rear baffle 112.

Specifically, referring to fig. 7 and 8, the rear baffle 112 is fixedly disposed on the frame of the delivery mechanism, and the front baffle 111 slides along the first guide bar 110, so that the distance between the front baffle 111 and the rear baffle 112 is increased, which is beneficial to the falling of the paper stack into the fixing position. When the paper stack is in the fixed position, the fourth driving assembly drives the front baffle 111 to slide along the first guide rod 110, so that the front baffle 111 abuts against the front part of the paper stack, and the rear baffle 112 abuts against the rear part of the paper stack, thereby aligning the front part and the rear part of the paper stack.

Referring to fig. 7 and 8, the second alignment assembly includes: the second guide rod 120 is perpendicular to the projection of the first guide rod 110 on the horizontal plane, at least one side baffle 121 is connected with the second guide rod 120 in a sliding mode, and the fifth driving assembly is connected with at least one side baffle 121 in a driving mode so that the two side baffles 121 can be close to or far away from each other.

Specifically, referring to fig. 7 and 8, one of the two side guards 121 may be fixedly disposed, wherein one side guard 121 can slide along the second guide rod 120 under the action of the fifth driving assembly, and the distance between the two side guards 121 is enlarged, so that the paper stack falls into the fixing position, after the paper stack falls into the fixing position, the slidable side guard 121 slides along the second guide rod 120 and abuts against one side surface of the paper stack, and the other fixed side guard 121 abuts against the other side surface of the paper stack, thereby aligning the left and right side surfaces of the paper stack.

Referring to fig. 7 and 8, the paper finishing assembly 100 further includes two paper supporting plates 122 and sixth driving assemblies, the two paper supporting plates 122 are disposed higher than the rear baffle 112, and the two sixth driving assemblies are respectively connected to one paper supporting plate 122 in a driving manner so as to enable the two paper supporting plates 122 to approach or separate from each other; when the two paper supporting plates 122 are close to each other, the paper supporting plates 122 are used for supporting the paper stack; when the two knock-out plates 122 are far away from each other, the stack of sheets falls from the knock-out plates 122 onto the movable curtain 300.

Specifically, referring to fig. 7 and 8, since the back board 112 is fixedly disposed, when the sheet bundle enters the fixing position from above the back board 112, the sheet bundle has a certain drop from the fixing position. The stack of sheets is moved onto the knock-up plate 122 before the stack of sheets is moved onto the movable curtain 300. Particularly, the upper surface of the paper supporting plate 122 is higher than the top of the rear baffle 112, the two sixth driving assemblies respectively drive the two paper supporting plates 122 to be close to each other, so that the paper stack can be supported by the paper supporting plates 122 before entering the fixed position, and then the two sixth driving assemblies respectively drive the two paper supporting plates 122 to be far away from each other, so that the paper stack falls into the fixed position, namely, the paper stack moves to the movable curtain 300, on one hand, the height drop of the paper stack when the paper stack falls into the fixed position is reduced, on the other hand, the paper stack can horizontally fall into the fixed position from the paper supporting plates 122, and the damage of folds and the like caused by the fact that the front end of the paper stack is obliquely inserted into the fixed position is avoided.

Referring to fig. 7 and 8, the fifth driving assembly includes a screw rod including two sections with opposite thread directions, and two side guards 121 respectively disposed on one of the two sections of the screw rod.

Specifically, referring to fig. 7 and 8, two side guards 121 can be connected to two segments of the screw rod by nuts, and the fifth driving assembly drives the screw rod to rotate because the side guards 121 are connected to the screw rod in a sliding manner while being connected to the second guide rod 120 in a threaded manner. The side fence 121 cannot be rotated and thus the side fence 121 will be linearly moved in the extending direction of the lead screw. And because the thread directions of the two sections of the screw rod are opposite, the moving directions of the two side baffles 121 are opposite, so that the two side baffles 121 can be far away from or close to each other when the fifth driving combined part drives the screw rod to rotate. The fifth driving assembly adopts a screw rod as a transmission part, so that the movement of the two side baffles 121 is more accurate, and the structure is compact.
