Description

A paper conveying device

technical field

The invention relates to an improved invention of a paper conveying device, in particular to a paper conveying device of a copy paper packaging machine.

Background technique

The large reams are cut into small reams and then transported to the packing place for packaging and collection. A large ream can be cut into four small reams at a time, and only one pack of reams is packed at a time when packaging, so the stacked reams should be evenly separated when the paper is conveyed, and the conveying speed of the reams should be the same as that of the packaging. time and speed coordination. There are some problems in the existing paper conveying device. 1. When the reams are cut into four piles of small reams, the four piles of small reams are closely attached to each other; 2. It takes a certain amount of time to cut the reams, so The spacing between the first four reams and the last four reams is too wide. To sum up, the distance between the reams on the existing conveyor belt is not equal, so it is difficult to coordinate the running speed of the conveyor belt with the packaging time, and the conveyor belt is intermittently conveyed, which not only affects the production efficiency, but also affects the production parts. Cause damage, reduce its service life, and increase production costs.

Contents of the invention

In view of the technical problems existing in the background technology, the technical problem to be solved by the present invention is to provide a paper conveying device that evenly separates paper to facilitate paper packaging, thereby improving production efficiency and reducing production cost.

In order to solve the above technical problems, the present invention is realized by adopting the following technical scheme: the paper conveying device includes a conveying platform and an electrical controller, and is characterized in that the conveying platform is divided into a conveying part, a chasing part and a separating part in sequence , there is a paper sensor between the conveying part and the chasing part, the paper sensor is connected with an electrical controller, the conveying part is provided with a conveyor belt A, and the chasing part is provided with a conveyor belt B and a conveyor belt C , the chasing section is further divided into an air supply area and a windless area, air holes are provided on the conveyor belt B and the conveyor belt C in the air supply area, and the air holes on the conveyor belt B and the conveyor belt C are respectively connected to their respective The air pump is connected, the air pump is connected with the electrical controller, the windless area is only equipped with a conveyor belt C, the conveyor belt B is synchronized with the conveyor belt A, and the conveyor belt C is slower than the conveyor belt B , the separating part is provided with a conveyor belt D, and the conveying speed of the conveyor belt D is faster than that of the conveyor belt C.

The conveyor belt C is arranged on both sides of the conveyor belt B.

In the present invention, the conveying table is divided into a conveying part, a chasing part and a separating part. After cutting, the paper is stacked on the conveying belt A of the conveying part and transported forward. In the chasing part, the paper cut after catching up Keep the same distance between the front and rear cut papers, and finally the separation part quickly separates the stacked papers on the conveyor belt, so that the front papers enter the next process, and the pile of papers is relatively different from the latter paper. If the gap is large, the time when the latter paper is conveyed on the conveyor belt is consistent with the time when the previous paper is packaged, so after the previous paper is packaged, the latter paper just enters, and so does the following paper. The invention adopts conveyor belts with different speed ratios combined with the conversion of blowing and suction in the air supply area, so that the paper can be quickly separated after being quickly closed, so as to coordinate with the packaging of the paper, and the conveyor belts are all conveyed at a uniform speed, without the need for Intermittent, thus improving production efficiency, reducing production costs and prolonging the service life of the conveyor belt.

Description of drawings

The working principle and relevant details of the present invention will be further described below in conjunction with the accompanying drawings.

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

With reference to the accompanying drawings, this kind of paper conveying device includes a conveying platform and an electrical controller. The conveying platform is divided into a conveying part 1, a chasing part 2 and a separating part 3 in turn, and a There is a paper sensor 8, the paper sensor 8 is connected with an electric controller, the conveying part 1 is provided with a conveying belt A4, and the chasing part 2 is provided with a conveying belt B5 and a conveying belt C6, and the conveying belt C6 is provided with On both sides of the conveyor belt B5, the chasing section 2 is further divided into an air supply area 10 and a windless area 11, the conveyor belt B and the conveyor belt C of the air supply area 10 are all provided with air holes 9, and the conveyor belt The air holes on the belt B5 and the conveyor belt C6 are respectively connected to the respective air pumps, and the air pumps are connected to the electric controller. The windless area 11 is only provided with the conveyor belt C6, and the conveyor belt B5 and the conveyor belt A4 are synchronized. The conveyor belt C6 is slower than the conveyor belt B5, and the separating part 3 is provided with a conveyor belt D7, and the conveyor belt D7 is faster than the conveyor belt C6.

The paper of the present invention is sent to the conveying part after cutting, that is, the paper is conveyed forward by the conveying belt A4. When the frontmost paper reaches the paper sensor 8, the paper sensor 8 sends the signal to the electric controller, and the electric control The device sends instructions to the air pump, at this time the air holes on the conveyor belt C6 in the catch-up area start to blow air, and the air holes on the conveyor belt B5 suck air, that is, the two ends of the paper are blown by the conveyor belt C6, and the middle part is blown by the conveyor belt B5 The paper is sucked, so the paper is conveyed by the conveyor belt B5, and the conveying speed of the conveyor belt B5 and the conveyor belt A4 are equal, so far the paper is in a state of constant speed, until the end of the last paper reaches the paper sensor at 8 o'clock, the conveyor belt C6 The air holes on the conveyor belt B5 start to suck air, and the air holes on the conveyor belt B5 blow air. Therefore, the paper is conveyed by the conveyor belt C6 instead. Since the paper is on the same conveyor table when the conveying speed is changed, there will be no damage to the paper. affect, and will not change the spacing between adjacent sheets. When the paper passes from the air supply area 10 to the back 11 of the windless area, the last cut paper is sent to the conveying part 1. When the front end of this part of the paper reaches the paper sensor 8, it is conveyed by the conveying belt B5, because The conveying speed of the conveyor belt B5 is faster than that of the conveyor belt C6, so the rear-cut paper quickly catches up with the front-cut paper. When the end of the rear-cut paper reaches the paper sensor 8, the rear-cut paper just catches up. The front-cut paper makes the distance between the front and back paper equal, and the conveying in the air supply area is also restored to the conveyor belt C6, so that the rear-cut paper catches up with the front-cut paper, and the rear And so on for cut paper. When the paper enters the separating part 3 from the chasing part 2, since the conveying speed of the conveying belt D7 of the separating part 3 is faster than the conveying belt C6, once the paper enters the conveying belt D7, the paper will be separated from the latter pile of paper quickly, And the paper is sent to the next process of paper packaging by the conveyor belt D7, and the next pile of paper continues to be conveyed by the conveyor belt C6 until it enters the conveyor belt D7, so there is a certain time gap between the front and back paper entering the paper packaging process, and this time is just right. Specialized in the packaging of paper, so the paper does not need to be interrupted during the conveying process, which greatly speeds up the production efficiency, reduces downtime, reduces production costs, and prolongs the service life of the conveyor belt.
