Paper tearing device and method

Abstract

The invention discloses a paper tearing device and method. The paper tearing device comprises a rack, a paper feed roller set, a paper discharge roller set, a power transmission mechanism and a paperejecting opening member; a paper passage is arranged in the rack, and the paper passage is provided with a bending section; the paper feed roller set, the paper ejecting opening member and the paper discharge roller set are sequentially arranged in the paper advancement direction of the paper passage; the paper feed roller set is movably connected to the rack, when the paper feed roller set is driven to move, the paper feed roller set is used for driving paper to move in the paper passage in the paper advancement direction or the paper retreating direction; and the paper discharge roller set is movably connected to the rack, and when the paper discharge roller set is driven to move, the paper discharge roller set is used for driving the paper or torn discharged paper to move in the paper passage in the paper advancement direction. By means of the paper tearing device and method, continuous paper with tear lines can be well torn, single paper output or multi-paper output can be achieved, the structure is compact, the cost is low, the paper can be accurately disconnected at the corresponding tear lines of the paper, and the device is also very convenient to use.

Description

technical field [0001] The invention relates to a paper tearing device and method, which is suitable for tearing continuous paper with tear lines. Background technique [0002] At present, a kind of continuous paper with tear lines between adjacent papers is widely used, such as instant lottery tickets (scratch lottery), the paper of instant lottery tickets (scratch lottery) is a kind of hard paper, continuous There is a tear line between the two lottery tickets, that is, like a sewing thread, after being partially perforated, it is easy to tear along the perforation line. The sales of traditional instant lottery tickets are sold manually, that is, as many tickets are torn as needed. In the self-service ticket vending machine, a device is required to complete the tearing action: due to unattended self-service ticket sales, at least one must have These performances: [0003] 1) Very low paper jam rate, that is, lottery paper is not easy to get stuck in the machine; [0004...

Problems solved by technology

[0004] 2) Re-sending is not allowed, that is, buying one and not exporting two;

[0005] 3) Since it is a continuous ticket, when the tearing or cutting performance is not good, at least multiple tickets cannot be pulled out by the customer;

[0009] Although the first type has the advantages of simple structure and low cost, it also has some disadvantages. For example, if two sheets of paper are connected by masking tape, it is not easy to tear (in self-service ticket vending machines, it is often not that the lottery tickets are sold out, and then To add lottery tickets, this may cause users to wait, and it is very likely to give up buying tickets, so the current method is to stick new tickets to the back of the previous stack of tickets with masking tape when they are about to be sold out, so that there can be uninterrupted ticket purchase experience)

There is even a risk of adhesive tape sticking to the edge of the knife and affecting performance

In addition, the lottery ticket must be cut off, which requires a larger space for the ticket outlet (at least greater than the length of the lottery ticket itself), and a box for holding the lost ticket. In some applications, it needs to take up less space. case, not very friendly;

[0010] The second type has a complex structure and requires at least 2 sets of systems --- paper feeding system and cutter system, each with a power unit, and the paper feeding system may even require 2 sets of power systems (need to tighten the face), which is more expensive

In addition, the most obvious problem with this structure is that there will be errors in paper feeding, and the paper feeding errors will accumulate (any paper feeding system will have errors, only the first type of system is based on the most fragile tear line It is the bending and tearing line, so the error will not be accumulated. The position of the incision in the second structure depends entirely on the accuracy of paper feeding, and the re-alignment is based on the incision, so there must be error accumulation)

This type of structure is also applied to the sale of invoices, such as the sale of value-added tax invoices. Due to the existence of accumulated errors, the incision of the later bills deviates greatly from the tear line, destroying the integrity of the bills and even making them unusable.
