A stapler is a machine or tool for binding pages or papers into a book.Can improve the automation of book binding.
Stapler structure is simple, generally only used for binding small thickness of the page paper, or paper bags, packaging bags seal.
You may have used a stapler, but do you know how a stapler works?Below small make up to introduce to you.
Introduction to the structure principle of stapler
1. Stapler structure
However, this small tool is also a mechanical structure, part of the market stapler also clever use of labor-saving mechanism, making the book to more convenient, easier to operate.First to the general stapler structure has a general understanding.
Ordinary stapler includes push, pin, support plate, shape-shifter, rivet, pressure device, base, spring, shrapnel, positioning shaft stapler parts, this connecting rod transmission structure plays the function of automatic spring back to push when the staple is installed, when the staple is closed on the handle and automatically make the push to work, resist the staple.
2. Basic functions of stapler
According to the function importance of stapler, the function of stapler is divided into main function, secondary function and auxiliary function.The main functions include needle mounting and stitching, the secondary functions include changing the shape of needle binding, and the auxiliary functions include anti-skid and anti-noise functions. Each function can be divided into some sub-functions according to its implementation steps.
The needle function can be divided into the cover opening function, the end cover opening function, the needle placing function, the fixed needle function and the cover closing function.Stitch function can also be subdivided into book function, semi-automatic needle function, binding function, automatic top function, automatic rebound function and ham book function;The function of changing the shape of needle binding can be divided into the function of ejecting the needle mold, changing the shape of the needle mold, fixing the needle mold on return trip and locating the needle mold.Anti-skid and anti-noise function;Trademark display function.
3. How the stapler works
Ordinary stapler tableland principle of work is in hand, when you push hard on the stapler end cover jingse, needles and the fixture will turn around the connecting pin, as people keep up of power, jingse will turn into from its natural state, the jingse will up and down around the connecting pin is slightly larger than a needle high approximation of up and down movement, end cover the spring compression, compression shrapnel, then drives the downward movement of the needle, needle after movement distance to be exposed to need to binding object and under the action of human through the object, the needle will encounter the mold after through the object, the needle bending, so as to realize the needle penetration between objects and binding;
After binding, the force on the end cover of the needle is removed. At this time, the shrapnel will rebound, and the needle, clamp, top and end cover will rise under the action of elasticity.The extension of the push spring allows the needle to be fed again, returning the stapler to its original state and waiting to be bound again.
4. Description of connection mode and characteristics between parts
Way of connection between parts and parts are mainly handle with plate pin connection, handle and deformation of welding, the handle of the shell and plate, positioning pin connection shaft and bearing plate welding, positioning and welding, for the spring in the pushing course of welding, for the spring with the driver in the pushing course of connection plate and the pin base, deformation and rivet connection, the deformation of base and the base of interference fit, trademarks and interference fit of base.
