Flat knitting machine mangling device with position varying with gap size

Abstract

A flat knitting machine mangling device with position varying with gap size is provided. The flat knitting machine mangling device includes a driving element, a fixing base disposed on a cam supporting base, a sliding base disposed to correspond to the fixing base, a limiting block combined with the fixing base and limiting the sliding base to only slide relative to the cam supporting base, a mangling sheet supporting arm and a mangling sheet disposed on the mangling sheet supporting arm. The driving element is started when a knock-over bit cam makes a displacement stroke. The sliding base is provided with a guide block and makes a regulation stroke relative to the cam supporting base when the driving element is started. The guide block drives the mangling sheet to move to change a mangling position when the sliding base makes the regulation stroke.

What is claimed is: 
     
         1 . A flat knitting machine mangling device with position varying with gap size, comprising:
 a driving element started when a knock-over bit cam makes a displacement stroke;   a fixing base disposed on a cam supporting base;   a sliding base disposed correspondingly to the fixing base and provided with a guide block, the sliding base making a regulation stroke relative to the cam supporting base when the driving element is started;   a limiting block combined with the fixing base and limiting the sliding base to only slide relative to the cam supporting base;   a mangling sheet supporting arm fixed to a yarn feeder guide rod with one end of the mangling sheet supporting arm and provided with an installing base on the other end of the mangling sheet supporting arm, wherein a passage is formed in the installing base; and   a mangling sheet comprising a control section connected with the guide block, a connection section extending from the control section and penetrating through the passage, and a mangling section extending from the connection section and facing a needle bed, wherein the control section leads the mangling section to move when the sliding base makes the regulation stroke, so as to change a mangling position.   
     
     
         2 . The flat knitting machine mangling device with position varying with gap size of  claim 1 , wherein the driving element comprises a combining part connected with the knock-over bit cam and a pushing part connected with the combining part; the driving element makes a driving stroke for allowing the pushing part to move when the knock-over bit cam makes the displacement stroke; one side of the sliding base is provided with an inclined guide path in which the pushing part is disposed; and the sliding base makes the regulation stroke relative to the cam supporting base when the driving element makes the driving stroke. 
     
     
         3 . The flat knitting machine mangling device with position varying with gap size of  claim 2 , wherein the limiting block comprises a first hook part that protrudes towards the mangling sheet supporting arm; and the mangling sheet supporting arm comprises a second hook part disposed on the installing base, protruding towards the limiting block and combined with the first hook part. 
     
     
         4 . The flat knitting machine mangling device with position varying with gap size of  claim 2 , wherein the sliding base has a first long hole in which the fixing base is disposed. 
     
     
         5 . The flat knitting machine mangling device with position varying with gap size of  claim 4 , wherein the mangling sheet comprises a second long hole disposed on the connection section; and the installing base comprises at least one installing hole communicated with the passage and providing an installing element corresponding to the second long hole to limit the mangling sheet. 
     
     
         6 . The flat knitting machine mangling device with position varying with gap size of  claim 5 , wherein the mangling sheet comprises a guide rod disposed on the control section; and the guide block is provided with a groove in which the guide rod is disposed. 
     
     
         7 . The flat knitting machine mangling device with position varying with gap size of  claim 2 , wherein the mangling sheet comprises a second long hole disposed on the connection section; and the installing base comprises at least one installing hole communicated with the passage and providing an installing element corresponding to the second long hole to limit the mangling sheet. 
     
     
         8 . The flat knitting machine mangling device with position varying with gap size of  claim 2 , wherein the mangling sheet comprises a guide rod disposed on the control section; and the guide block is provided with a groove in which the guide rod is disposed. 
     
     
         9 . The flat knitting machine mangling device with position varying with gap size of  claim 2 , wherein the sliding base comprises a first surface that faces the cam supporting base, and a second surface that faces the limiting block; and the inclined guide path extends from the first surface to the second surface toward the knock-over bit cam. 
     
     
         10 . The flat knitting machine mangling device with position varying with gap size of  claim 9 , wherein the mangling sheet comprises a guide rod disposed on the control section; and the guide block is provided with a groove in which the guide rod is disposed. 
     
     
         11 . The flat knitting machine mangling device with position varying with gap size of  claim 1 , wherein the driving element is composed of a motor and a gear connected with the motor; and one side of the sliding base is provided with a rack that comes into contact with the gear. 
     
     
         12 . The flat knitting machine mangling device with position varying with gap size of  claim 11 , wherein the limiting block comprises a first hook part that protrudes towards the mangling sheet supporting arm; and the mangling sheet supporting arm comprises a second hook part disposed on the installing base, protruding towards the limiting block and combined with the first hook part. 
     
     
         13 . The flat knitting machine mangling device with position varying with gap size of  claim 11 , wherein the sliding base comprises a first long hole in which the fixing base is disposed. 
     
     
         14 . The flat knitting machine mangling device with position varying with gap size of  claim 13 , wherein the mangling sheet comprises a second long hole disposed on the connection section; and the installing base comprises at least one installing hole communicated with the passage and providing an installing element corresponding to the second long hole to limit the mangling sheet.
