Description

Paper collecting device of offset press

Technical Field

The utility model relates to a paper collection device of lithographic offset press.

Background

An offset printing press is a kind of offset printing press, in which printing images are first printed on a blanket cylinder from a printing plate and then transferred to paper by the blanket cylinder. Offset presses can be divided into sheet-fed offset presses and web-fed offset presses according to different paper feeding modes; the printing color number completed by one-time paper feeding can be divided into single-color, double-color, four-color and multi-color printing machines; the full-paper printing machine can be divided into a small offset press, a six-opening, four-opening, two-opening and full-paper printing machine according to the maximum paper breadth to be printed, and a double-sided printing machine capable of simultaneously finishing two-sided printing by one-time paper feeding is also arranged. The sheet-fed offset press is a lithographic printing press, is used for printing high-grade commercial printed matters and packaging printed matters, and is the mainstream of modern paper printing.

At present, the collection modes of paper after the printing of an offset press is finished are mainly divided into two modes, 1, the paper is directly sent out of a paper outlet of the offset press through a discharging roller, the paper falls to the ground, and workers collect the paper falling to the ground; 2. and a collecting box is arranged at the paper outlet, so that the paper falls into the collecting box. Both of the above approaches have drawbacks in operation. 1. The paper falling to the ground needs to be collected manually, the labor cost is high, and after the paper falls to the ground, the paper is likely to be smeared by dust on the ground, so that the quality of the paper is affected; 2. the bottom and the opening of the collecting box have larger height difference, and in the process that paper falls to the bottom from the opening, the paper flutters in a larger space, so that the paper can fall into the collecting box in a scattered manner, and the scattered collection amount is far less than the amount of the paper stacked in order.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a lithographic offset press's paper collection device can reduce artifical participation degree when the paper is collected, can also improve the regularity nature that the paper was collected.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a paper collecting device of a lithographic offset press is characterized in that: comprises a chassis and a collecting box;

the chassis is provided with a lifting driving part and a lifting plate connected with the lifting driving part;

the collecting box is arranged on the bottom frame and comprises a box frame and a bottom plate, the upper opening and the lower opening of the box frame are arranged, a supporting part is arranged on the inner wall of the lower side of the box frame, and the bottom plate is arranged on the supporting part and corresponds to the lifting plate up and down.

Preferably, the lifting driving part is an electric push rod.

Preferably, the supporting part is a supporting wall formed on the inner wall of the box frame.

Preferably, the bottom wall of the box frame is provided with a forklift opening.

Preferably, the underframe comprises a table plate, a mounting plate and support legs; the table plate is arranged at the top of the supporting leg and is provided with an opening avoiding the lifting plate; the mounting plate is mounted on the supporting legs and located below the table plate, and the lifting driving part is mounted on the mounting plate.

The utility model has the advantages that: when collecting the paper, reduced the space of paper whereabouts for the paper comes out from the exit slot back, steady falling on the bottom plate has improved the regularity that the paper was collected, and has reduced the cost of artifical arrangement.

Detailed Description

The paper collecting device of the offset lithographic printing machine according to the present invention will be further described with reference to fig. 1 to 3.

A paper collecting device of a lithographic offset press is characterized in that: comprises a chassis 4 and a collecting box 3;

the chassis 4 is provided with a lifting driving part 5 and a lifting plate 6 connected with the lifting driving part 5;

the collecting box 3 is arranged on the bottom frame 4, and the collecting box 3 comprises a box frame 31 and a bottom plate 32, the box frame is arranged with an upper opening and a lower opening, a supporting part 313 is arranged on the inner wall of the lower side of the box frame 31, and the bottom plate 32 is arranged on the supporting part 313 and corresponds to the lifting plate 6 up and down.

During working, the bottom frame 4 is placed at the paper outlet 11 of the offset press 1, and the collecting box 3 is placed on the bottom frame 4, so that the bottom plate 32 corresponds to the lifting plate 6 up and down; after the collecting box 3 is just placed on the bottom frame 4, the bottom plate 32 is pushed upwards by the lifting driving part 5, so that the distance between the bottom plate 32 and the upper opening of the box frame 31 is 10-30 cm; in the collecting process, the lifting driving part 5 drives the bottom plate 32 to slowly move downwards, so that the paper has a stacking space in the collecting box 3, namely, in the whole collecting process, the height difference between the upper opening of the box frame 31 and the topmost paper is kept between 10 and 30cm until the bottom plate 32 falls back to the supporting part 313, and the collection is finished; the collecting box 3 is moved away by a forklift, and the empty collecting box 3 is replaced for circulating collection. In the process, the falling space of the paper is reduced, so that the paper can stably fall on the bottom plate 32 after coming out of the paper outlet 11, the paper collection uniformity is improved, and the manual sorting cost is reduced; on the other hand, the split structure of the box frame and the bottom plate can enable the box frame to be repeatedly used after the bottom plate is moved out of the box frame, so that the use flexibility is improved, the cost is reduced, the box frame and the bottom plate are moved down by the aid of the forklift, the stability of paper carrying can be guaranteed, and the problem that paper is scattered is avoided.

The embodiment is further configured as follows: the lifting driving part 5 is an electric push rod with adjustable speed, the lifting plate is in threaded connection or is inserted into a telescopic rod of the electric push rod, and the electric push rod can drive the bottom plate 32 to descend at a speed which is matched with the paper discharging stacking speed of the offset printing machine 1 through adjusting the telescopic speed of the electric push rod, so that the height difference between the uppermost paper in the collecting box 3 and the upper opening of the box frame 31 is kept between 10 cm and 30 cm. The speed-adjustable electric push rod is a conventional one, and can be purchased directly from the market for use, so the specific structure of the push rod is not described in detail in this embodiment.
