Description

Protect the mountain on the computer flat knitting machine

Technical field

The utility model belongs to technical field of knitting machinery, relates in particular on a kind of computer flat knitting machine and protects the mountain.

Background technology

Protect the mountain on the computer flat knitting machine and be mainly used in stitch on the knitting needle is sent in the track that turns over the pin triangle, send into and require speed steady in the process, the path is level and smooth, can not produce by a relatively large margin vibrations or sudden unplanned displacement.It is single to protect the mountain structure on existing, adopts right-angle structure more, and the side that promptly protects the mountain on each piece is vertical with the base, and the base also is a flat.Make simply though protect the mountain on this type,, make knitting needle stable inadequately in motion process, and vibrations are bigger, are prone to cause the damage of knitting needle because the track that takes the needle that protects the mountain on this type and provide needs knitting needle often to do the right angle turnover.

Summary of the invention

The utility model aims to provide on a kind of computer flat knitting machine and protects the mountain, and stable, level and smooth knitting needle moving line can be provided.

For this reason, the technical scheme of the utility model is such: protect the mountain on the computer flat knitting machine, be installed on the rectangle motherboard, protect the mountain on described and be divided into three of left, center, right; Piece bottom, a left side is a Cam Track, and this Cam Track divides four sections from left to right, first section ratio the 4th segment length; The 3rd section ratio second segment length, second section is parallel with the motherboard top margin, and first section is 128 ° with second section angle; The 3rd section is 178 ° with second section angle; The 4th section with the 3rd section angle be 128 °, the 4th section near on protect piece in the mountain, each section is all to top margin and transfers; Right piece bottom is identical and in the opposite direction with left piece; In piece be " recessed " shape, left-right symmetric, the bottom is a Cam Track, divides three sections, about two sections and stage casing respectively angle be 128 °; The Cam Track turning point transition of each piece is a fillet.

The turning angle of each piece side section of the utility model all adopts 128 °, and this angle is to protect the best angle on mountain on the computer flat knitting machine, and in the time of avoiding turning angle less than 128 °, knitting needle is smoothly smooth and easy inadequately.Knitting needle often needs to change height in the process of taking the needle; And offsets in height takes place because vibrations can not fit like a glove with desired trajectory through regular meeting in knitting needle when taking the needle, and the side section of therefore protecting the mountain in the requirement reaches the height of appointment; Because the size of motherboard is limit; The lateral length of each piece can not be long, receives the length institute limit for height degree can't be up to standard when causing side section turning angle greater than 128 °, and the utility model can be avoided this situation.Two two sections of centres about the utility model---the 3rd section with 178 ° of angles of second section folder, this angle can make knitting needle before getting into the 4th section, on vertically, have movement velocity, makes knitting needle get into the 4th section and then to get into the process of turning over the pin triangle more steady.In addition, fillet is all used in each turning point of the utility model, the flatness when further promoting knitting needle.

The utility model is the Cam Track transitions smooth that the stitch of knitting needle epimere provides, and turning angle is reasonable, can not occur than big bang and skew, the protection knitting needle and on protect mountain self, effectively reduce fault rate, prolong knitting needle service life.
