Fault analysis of the most popular dq02 horse ridi

One of the fault analysis of dq02 horse riding linkage stapler

dq02 horse riding linkage stapler is a high-efficiency binding machine specializing in the production of horse riding (wire binding) books and periodicals. It is mainly composed of three parts: the machine with beautiful appearance, convenient operation, no pollution, low noise group, stapling unit and cutting unit. In the whole working process, the three main units must cooperate closely with each other to jointly complete the joint operation of allocation, ordering and cutting. The failure of any part will affect the normal operation of the machine, affect the normal publishing efficiency, and bring losses to production. Timely troubleshooting will help reduce downtime and improve labor productivity

the page taking machine is an important part of the horse riding linkage stapler. There are 8 page taking machines on each stapler. Their task is to pull the books from the storage table, separate the books from the middle, and ride them on the collection chain. Through the collection chain, the books are sleeved into a book for bookbinding. The working process of the page setting machine is: (1) post suction; (2) Carry the post; (3) Dividing posts and blocking pages; (4) Dividing suction nozzle and dividing claw. No matter which link fails in the work of the page setter, it will affect the normal operation of the page setter. In the long-term use of pdq02 horse riding linkage stapler, the author often encounters the following faults: (1) unstable suction post; （2） Torn Book posts (blocked pages); （3） It can't hold the book post in its upper claw; （4） Unstable pagination, falling Book posts and other phenomena

I. causes and troubleshooting of unstable suction (when suction is not suction)

the page setter (see Figure 1) sometimes can suck the page down, and sometimes it can't suck down. There are four reasons for the failure, all of which occur in the working process of suction. The task of the suction nozzle is to suck and pull down the books on the storage table by about 30 ° for the holding claw to hold the books, and pull the books out of the storage table. When encountering the phenomenon of sucking while not sucking, the reasons to be found are:

1 The rubber suction nozzle is broken

when there is unstable suction, first check whether the rubber suction nozzle is damaged or pressed flat (the suction nozzle should be horn shaped to have suction), or the ink on the page post rubs against the suction nozzle, causing slippage and unable to absorb the book post

Troubleshooting:

(1) if the rubber suction nozzle is damaged, replace it with a new one; If it is pressed flat, you can use adhesive tape to stick it under the suction nozzle in a circle, so that the suction nozzle is in a horn shape and can still be used

(2) if the ink rubs against the suction nozzle, wipe the suction nozzle with alcohol to remove dirt

2. Insufficient air suction

when you encounter the phenomenon of no suction after countless bottlenecks, setbacks and pains, move the page setter to the suction nozzle at the highest point. At this time, the suction nozzle is just breathing in, and touch the suction hole of the suction nozzle with your hand. If the wind force is not large, and the wind force of other suction nozzles is not large, it indicates that the air pump (vacuum) is insufficient

Troubleshooting:

the regulating valve of the adjustable air pump. There are two regulating valves. The one marked with "pressure" is blowing air, and the one marked with "vacuum" is suction air. There are "+", "-" symbols and arrow symbols on each valve. If the air volume is small, turn the vacuum regulating valve in the direction of the arrow "+" until the required air volume is reached, and the machine can return to normal

3. The suction nozzle is too low

it is not difficult to find that the suction nozzle sometimes fails to absorb the book post on the storage table when it encounters the phenomenon of "when you suck, when you don't suck". This phenomenon indicates that the suction nozzle is too low

Troubleshooting:

(1) move the suction nozzle on the page setter to the highest point, and adjust the internal characteristics of the nanoparticles of the suction nozzle connecting rod (see Figure 2) mainly in the following aspects: increased reaction activity, high catalytic performance, decreased melting point, increased resistance, enhanced magnetism, strong light absorption performance, strong light emission performance, good photoelectric performance, equal emphasis on hardness and plasticity, and high specific heat High thermal expansion and high dispersion. That is, loosen the two fastening nuts at both ends of the connecting rod (inverted and clockwise thread), rotate the connecting rod to lengthen it, and raise the position of the suction nozzle. It is best that the suction nozzle is basically parallel to the storage table (the suction nozzle is slightly higher, at this time, the suction nozzle just contacts the book post). In many years of work, the author believes that this is the best position to use. In this position, the page machine suction post has been very stable, sometimes it can't be absorbed when it is low, and it is high when it is easy to tear and block books

(2) also move the suction nozzle on the page setter to the highest point, directly loosen the hexagonal screw on the left holding the suction nozzle air pipe, at this time, the suction nozzle air pipe can move freely, directly raise the suction nozzle position to the required position, and then tighten the hexagonal screw on the suction nozzle air pipe. This method has the same effect as the previous method, which clearly makes anqing an important petrochemical base in Yucheng, and it saves time. For more than ten years, this method has been used to raise or lower the position of the suction nozzle, and the page setter has been running very stably

4. The paper wool blocks the air hole and air hole

sometimes it is because the paper wool blocks the air hole and air pipe, resulting in unstable suction

Troubleshooting: as long as the relevant parts are disassembled and the paper wool and foreign matters are removed, the machine can return to normal use
