Description
Technical field
The utility model is related to field of textile machinery, specially a kind of improved tricot machine pulling device.
Background technology
Tricot machine is when running well, and fabric is constantly formed in knitting point, therefore must just have a set of special machine
Structure constantly from knitting point is drawn out the fabric of formation to come, and this mechanism is exactly pulling device.Traditional tricot machine drawing
Device is generally four-roller pulling device, but unfortunately, four-roller pulling device only pulls fabric, fabric table by four-roller frictional force
Face and the limited pressure of roll surface, cause frictional force small, and fabric tends to be braided the yarn pumpback in region or because machinery shakes
It is dynamic to creep, braiding horizontal stripe is produced, especially when running into the relatively low fabric of coefficient of friction, easily skids and can not effectively pull.
To solve the above problems, in the U of Chinese patent application prospectus CN 203393400, disclosing a kind of warp knit
The pulling device of machine, including a pair main pulling rolls, a pair of pair pulling rolls, the pressure rollers and friction roller that lean against in two main pulling rolls；
The gap adjusting mechanism one of radial direction is set at the two ends of friction roller, gap adjusting mechanism is installed in a secondary pulling roll wherein
Two；Bearing is installed at the two ends of described friction roller, and described gap adjusting mechanism one includes the bearing block for being enclosed on Bearing outer, set
There is spring, by adjusting regulating bolt of the spiral distance regulation spring to bearing block pressure, being enclosed in regulating bolt is used to position
Clamp nut, described a pair of main pulling rolls, pressure roller and surface of friction roller be surrounded by rough surfaced rubber covering.But what the documents were not enough
It is that its is complicated, cost is high, does not reach preferable uniformity coefficient through the tension force on the whole breadth of overtesting fabric, its selvedge
Quality cannot ensure that especially in machine vibration, the relatively low fabric of coefficient is examined in face of rubbing effectively to be pulled, and can not still be arrived
Up to the work of efficient stable.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part to lead there is provided a kind of improved tricot machine
Drawing device.
To realize the utility model purpose, the utility model uses following technical scheme：A kind of improved tricot machine drawing
It is provided with above device, including tricot machine frame, four-roller pulling device, the first roll surface of the four-roller pulling device in parallel
And tangent main pulling roll, the two ends of main pulling roll are installed in tricot machine frame by support base, the main pulling roll it is upper
Side is provided with pressure roller in parallel and tangent, and the two axial ends of pressure roller are separately installed with pressure regulation device, each pressure
Adjusting apparatus includes fixed seat, regulation spring, presetting nut and regulating bolt, and the pressure roller shaft end is set through fixed seat,
The fixed seat is fixed on above support base, and the regulation spring is arranged in fixed seat and positioned at the pressure being located in fixed seat
The top at roll shaft end, presetting nut is located at the surface of regulation spring, and the regulating bolt sequentially passed through at the top of fixed seat, presetting
Nut, regulation spring and pressure roller shaft end are simultaneously threadedly coupled with fixed seat, presetting nut and pressure roller shaft end respectively.
Further, the two ends of the main pulling roll are respectively equipped with positioning piece one, and the two ends of pressure roller are respectively equipped with necessarily
Position part two, the axial displacement of roll body can be effectively limited by this keeper.
The tricot machine pulling device that the utility model is provided, its is simple in construction, by setting presetting nut and regulating bolt
Pressure of the settable regulation spring effect in position on pressure roller shaft end size and limiting value, to adjust pressure roller and main pulling roll
Change in location, the fabric of clamping is kept necessary adjustable chucking power, while controlling fabric to be led from knitting position to four-roller
Tension force on the Distance Shortened of the roll surface of drawing device first, the whole breadth of fabric evenly, can effectively improve the quality of selvedge, and
And the pressure that main pulling roll can clamp fabric with pressure roller contact surface can also keep normal work under vibrating conditions, can effectively prevent
The horizontal stripe of fabric face, the device in the case where not increasing power source also can normal work, its cost is low, reliable operation.
