Abstract
An adjustable tension top pin is used on a drafting assembly of a spinning machine, belonging to the technical field of the spinning, which is used to solve the problem of the unable adjustment of tensile force on an upper rubber ring. The adjustable tension top pin comprises a holding position in the middle portion, a working position and a tension position which are symmetrically arranged on two sides of the holding position, wherein the tension position after being improved is formed by tension reeds, wherein the lower portions of the tension reeds are clamped on the working position, and the tension ends thereof are bended in a circular arc shape. The utility model has the following characteristics that the tension reeds can automatically strain to realize the adjustable tension of the upper rubber ring after the upper rubber ring is elongated, thereby guaranteeing the evenness of spun yarns, and side retaining sheets are further arranged on two sides of the top pin for preventing flying from entering into the components of the top pin, finally a projected console is further arranged on the working position of the top pin to strengthen the control force for a strand of fibers, thereby further guaranteeing the evenness of spun yarns, and increasing the quality of resultant yarns.
Description
Technical field
The utility model relates to a kind of textile machinery accessories, is the pin of going up that is used for drafting device for spinning machine specifically, belongs to textile technology field.
Background technology
The effect of drafting assembly of spinning frame is with roving-drafting in the textile machine, and promptly the roller by three pairs of different rotating speeds draws back the rove fiber uniformly and stably and attenuates, and then forms spun yarn through twisting.In the spinning-drafting system, the drawing-off that is positioned at the drafting system middle part is a main drawing area, main drawing area by middle top roller, go up pin, around the two upper leather ring and middle bottom roller, downside pin, form jaw around the two hypodermis circle, and the motor fiber in the friction field counter extensioin district is implemented control in the middle part of producing thus, and the performance of main drawing area counter extensioin performance in whole drafting system plays key effect.Existing drafting system is used goes up pin because of due to the structural design, in use there is following point: 1. sell on and be provided with the tensioning position, this position can enclose tension to epithelium, but descends and can't adjust with prolonging upper leather ring elongation back tension service time, thereby influences the spun yarn uniformity; 2. upward have the triangle gap between pin dual-side and the upper leather ring, this gap easily makes flyings enter, and can influence normal drafting process when serious; 3. the jaw between the upper and lower apron is relatively poor to the control of floating fiber, has enlarged floating fiber speed change point distribution and unstability, influences yarn quality.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of and can keep tensile force automatically in upper leather ring elongation back, can stably be used for to sell on the adjustable tension of drafting device for spinning machine.
It is as follows to address the above problem the technical scheme that is adopted:
Sell on a kind of adjustable tension that is used for drafting device for spinning machine, comprise the holding area, the working position that is symmetricly set on the both sides, holding area and the tensioning position that are arranged on the middle part in the formation, its special feature is: described tensioning position is made of tension force reed 1, tension force reed bottom mounting board is 5 places in the working position, and its tension side 1-1 is the circular arc bending.
Sell on the above-mentioned adjustable tension that is used for drafting device for spinning machine, set up side catch 3, the dual-side that the side catch is triangular in shape, be positioned at pin.
Sell on the above-mentioned adjustable tension that is used for drafting device for spinning machine, set up protruding console 4, the protrusion direction of described protruding console is opposite with the tension side 1-1 direction of tension force reed, and height of projection is 5~10 millimeters, and protruding console top is an arc transition.
The utility model has been researched and developed a kind of pin of going up that improves spun yarn uniformity and yarn quality at the deficiencies in the prior art.It is as follows to go up the pin main feature: 1. the tensioning position is the tension force reed, and this tension force reed can rely on the elastic force auto-tensioning after the upper leather ring elongation, realize that upper leather ring tension force is adjustable, thereby guarantees that spun yarn is even; 2. set up the side catch at last pin dual-side, enter in the upper pin assembly to prevent flyings; 3. set up protruding console in last pin working position, the end of this projection console can increase a control point to yarn by upper leather ring, give full play to the advantage of apron controlling fiber and elastic floating jaw, strengthened control to the yarn fiber, further guarantee the uniformity of the spun yarn that spins, improve yarn quality.To sum up, the utility model is expected to become the existing regeneration product of going up pin to selling the improvement of carrying out traditionally.

The specific embodiment
Referring to Fig. 1, Fig. 4, Fig. 5, during constituting, the utility model comprises holding area 2, the working position 5 that is symmetricly set on the both sides, holding area and the tensioning position that is arranged on the middle part, described tensioning position is made of tension force reed 1, tension force reed bottom mounting board is 5 places in the working position, and its tension side 1-1 is the circular arc bending.Be characterized in as the tensioning position with the tension force reed: when upper leather ring prolong with service time extend after, the tension force reed can be automatically to stable tensile force of upper leather ring maintenance under the effect of elastic force.The installation of tension force reed can be adopted and mounting board sheet 1-2 is set in tension force reed bottom and sells the mode that the working position is provided with mounting board hole 5-1 and fix last, as Fig. 4, shown in Figure 5.
Referring to Fig. 1, Fig. 3, the utility model is set up side catch 3, and the side catch is triangular in shape, be positioned at the dual-side of pin, and the side catch can prevent that flyings from being entered in the upper pin assembly by the gap between last pin and the upper leather ring.
Referring to Fig. 1~Fig. 4, another improvement of the present utility model is to set up protruding console 4, and the protrusion direction of protruding console is opposite with the tension side 1-1 direction of tension force reed, and height of projection is 5~10 millimeters, and protruding platform top is an arc transition.As seen from Figure 6, protruding console end can increase a control point to yarn by the compressing upper leather ring, thereby strengthens the control to the yarn fiber.
