Wire Stapler common fault analysis


Wire stapler head work, through the feeding, cutting, forming, stapling, care equal to 5 parts, due to the feeding and stapler complex structure, precision, so a variety of daily binding book, when a fault occurs, Affect bookbinding quality and progress. According to their own in the past few years in the production of fault encountered, a case analysis as follows, for peer reference.

1. Do not send wire or do not send wire. The main reason is: the conveyor wheel or skateboard (package conveyor track) and other wear grooves, the wire can not rhythmically correct delivery, sometimes there is leakage, do not send phenomenon; wire quality unqualified, burr, not smooth or Not straight will affect the normal wire. 

2. Do not cut wire or cut constantly. The main part of the cutter and guide wire hole problems. Such as: the knife is less than the pre-positioning down with the guide shaft hole eye contact is too small; knife and guide wire shaft hole is too large, (cutting blade collapse), can not form a shearing effect; 3. Non-forming (that is, sawing): the main forming hook and molding skateboard with improper. Such as: forming hook feeding is not in place; molding hook and clip plate wear, wire can not send out; clip spring failure, wire caught, can not send the predetermined location. 

4. Card saw (wire is stuck). Mainly shaped hook is not appropriate. Such as: forming a larger hook wear, wire out of the groove, the wire stuck; wire straightening, reluctant delivery and then stuck; wire diameter improper (generally too large) or set heavy sawing. 

5. Nail saw irregular length (claws inconsistent). The main transport is not normal. Such as: improper feed swing adjustment, feeding wheel or feed skateboard wear, so that the wire can not be regularly transported. 

6 claws (feet) a long short or long are short; mainly due to improper adjustment. Adjust the thickness of the book by the book so that adjusted the length of the claw suitable for the same. 

7. Nail saw the tip out of the tip. This failure often occurs in thick thick hard book, it is a difficult problem. Its manifestations are in the book after the bend on the corner appear not to break and fracture of the spike, saw the cover hole will be broken or slippery, resulting in cover loss. The reason there are about three: wire diameter does not meet, the pressure is not correct, or tight hook (claw) push plate is too high, the tip of the wire after breaking off. 

8 claws (nail feet) pressure is not real or a compaction a pressure false. Reason: Tight claw (pallet) Push plate is too low, when up to a predetermined position, the nail can not hold the real, a pair of tight claws (claws) inconsistent or up to the predetermined position is not parallel. 

9. Set claw crooked. The main reason is that the wire quality is not good, there is a burr, not smooth and straight; wire is soft, and books booked improperly; forming the nail according to the angle is not vertical; forming skateboard inappropriate, such as the groove is too wide, Narrow or improper pressure. 

10. Book before the book should be based on book thickness, wire and book selected model, the length of the claw to regulate the relative symmetry. 

11. Adjust the "tight hook", requiring 2-3mm beyond the plane. According to this operation, the bound book will meet the quality requirements.
