Description
Technical field
The invention belongs to technical field of knitting machinery, particularly the secondary roller device of flat machine.
Background technology
The tractive of flat machine and curly course pull out the knitted fabric that forms exactly from knitting point, wherein secondary roller is an important tractive structure, mainly are made up of motor, sprocket wheel, main cloth wheel and compress wheel.Regulate the position between compress wheel and the main cloth wheel, can make compress take turns tractive fabric effectively.Gap length between main cloth wheel and the compress wheel and main cloth wheel and compress wheel cooperate the pulling force size that produces, and all directly have influence on the operating efficiency and the work quality of secondary roller.At present domestic secondary roller is a kind of to be through at compress wheel shaft one end the compress wheel handle being installed; Hand shaken handle during operation; Adjustment compress wheel location, this mode has not only increased cost of labor greatly, and tends to occur compress wheel location adjustment phenomenon not in place.
Those skilled in the art have proposed some improvement for this reason; Drive compress wheel and main cloth wheel respectively such as two motors; And both matches also are through motor-driven, can save labour turnover like this, but owing to need drive compress wheel and the action of main cloth wheel respectively through two motors; Increase number of components and parts, thereby increased production cost.
Summary of the invention
The secondary roller device that the purpose of this invention is to provide a kind of flat machine, it can only move with a motor-driven compress wheel and main cloth wheel, and can make things convenient for the position of regulating exactly between main cloth wheel and the compress wheel.
For this reason, the technical scheme that the present invention adopted is: the secondary roller device of flat machine comprises main cloth wheel and compress wheel; It is characterized in that: it also comprises some compress wheel assemblies; Said compress wheel assembly comprises compress wheel seat and fixed bar, and said fixed bar is fixed on an end of compress wheel seat, and the other end of compress wheel seat is taken turns coaxial the connection with compress; One side of compress wheel seat is provided with an adjusting device; Said adjusting device comprises an adjusting rod and a spring, and said spring one end and compress wheel seat are conflicted, and the other end and adjusting rod are conflicted; Also comprise a transmission device; Comprise a motor, drive sprocket, driven sprocket, driving gear, driven gear and freewheel clutch; Said motor arrives drive sprocket and driven sprocket through belt transmission; Driving gear that drive is meshed and driven gear running, said freewheel clutch and driving gear all are fixed on an end of fixed bar, and said driven gear is taken turns coaxial the connection with compress; Said secondary roller device also comprises a take-up device, and said take-up device comprises that one is fixed on the drawing rope on the compress wheel, and the said drawing rope other end is walked around the stay pile that is fixed on the frame, links to each other with spring; Said spring is fixed on the spring pedestal.
Further improve and be: said compress wheel is the hollow circular ring shape, and its two ends inwall is provided with some grooves, and compress wheel shaft correspondence position is provided with the convexity of equal number, with the groove coupling on the compress wheel.
Motor rotates through first drive sprocket of band drive synchronously, and drive sprocket drives the running of main cloth wheel; Simultaneously, drive sprocket drives driven sprocket synchronously through second and rotates, and driven sprocket drives the driving gear that is fixed on the fixed bar and rotates, and driving gear and driven gear mesh, and driven gear is coaxial with the compress wheel, therefore drives the compress wheel and rotates.Adopt this transmission mechanism can only need to drive compress wheel and the motion of main cloth wheel, practiced thrift production cost through a motor.
When needs move down the compress wheel location, only need push adjusting rod and make spring compress, force on the compress wheel seat, compress wheel seat pressurized moves down, because the compress wheel is to link to each other through the compress wheel shaft with the compress wheel seat, the compress wheel is also followed and is moved down.
When needs with the compress wheel location on timing, only need unclamp adjusting rod and get final product.In addition, sway in moving process in order to prevent the compress wheel, the present invention evenly offers groove on the inwall of compress wheel two ends, and correspondence position has convexity on the compress wheel shaft, and convexity is inserted in the groove, rotates when the compress wheel can stop the compress wheel when moving down.
Adopt after the said structure, can reach the position of fine setting compress wheel, thereby fabric that can the tractive all thickness has improved the well-balanced property of density of tractive fabric.
When just taking up one's knitting, needed base plate rising tractive fabric to go downwards to the position that roller can tractive, when playing base plate and rise, need compress wheel and main cloth wheel to open fully, to avoid and to rise the base plate collision.Therefore the present invention on an end of fixed bar, be provided with can only folk prescription to the freewheel clutch that rotates; When compress wheel and main cloth wheel tractive fabric; Both are in closure state, and this moment, main cloth wheel counterclockwise rotated, and compress wheel clockwise direction rotates; Fixed bar is motionless, and freewheel clutch rotates around the fixed bar axle; When compress wheel and main cloth wheel were opened, main cloth wheel rotation direction was changed into clockwise direction and is rotated, and driven sprocket drives driving gear and also clockwise rotates; At this moment because freewheel clutch and fixed bar are in the locking state, freewheel clutch drives original static fixed bar and clockwise rotates, because fixed bar and compress wheel seat are fixed together; And the compress wheel seat is to take turns coaxial the connection with compress; Therefore, compress wheel seat integral body also clockwise rotates, and driving the compress wheel is that axle clockwise rotates with the fixed bar; Thereby away from main cloth wheel, both are in released state gradually.
In order to improve the pulling force of roller to the cloth sheet, the present invention is provided with a take-up device.After starting motor; Rotate synchronously through sprocket wheel drive compress wheel and driving wheel, take-up device is a fixing drawing rope on the compress wheel, and the drawing rope other end links to each other with spring; And spring is fixed on the spring pedestal; Under the effect of spring force, make when compress wheel and main cloth wheel rotate synchronously, to the pulling force increase of cloth sheet.
The invention has the beneficial effects as follows: reduced the quantity of motor, only used a motor can drive main cloth wheel and the running of compress wheel, simultaneously, increased the adjusting device of take-up device, improved the ability of secondary roller tractive cloth sheet with fine setting compress wheel location; In addition, adopted the freewheel clutch structure, guaranteed that main cloth is taken turns and the compress wheel is opened fully.
