Abstract

The utility model relates to a regular jaw upper pin of an apron which can be elastically tensed on a spinning machine, the structure thereof is as follows, rubber ring support plates are respectively connected on both sides of the lower part of a support frame, and reeds are connected on the rubber ring support plates. The regular jaw upper pin forms an apron tensing mechanism through the arrangement of the elastic reeds, a sleeved apron can be always maintained in the tense state under the role of the mechanism, thereby achieving the purpose of eliminating the slip of the apron and allowing the running of the apron to be smooth, and the gripping role of the apron to yarn strips can be basically maintained consistent during the drafting process, thereby ensuring the yarn quality. The regular jaw upper pin is applicable to the regular jaw upper pins with the different widths and can also be used on other types of upper apron pins; furthermore, the regular jaw upper pin can be applicable to band drafting devices of roving machines and spinning machines.

Description

But sell on the regular jaw of elastic tension apron

Technical field

The utility model relates to the parts on a kind of spinning machine, but sells on specifically a kind of regular jaw of band elastic tension apron.

Background technology

Pin is one of main drafting unit in the spinning machine yarn drafting system on the regular jaw, it should effectively grip the motion of fiber, the ensuring smooth transmission that keeps upper and lower apron again, and it also directly acts among the drawing-off and gripping of fiber, in the drafting process of fiber, motion to controlling fiber plays an important role, and is therefore very crucial to the influence of yarn quality.The structure of selling on the existing regular jaw is to be connected to the cushion rubber supporting plate respectively on the both sides of bracing frame bottom.Apron is to be socketed in respectively on these two cushion rubber supporting plates of selling on the regular jaw.Pin is not owing to there is strainer on the existing fixed jaw, thereby do not have the characteristic of apron being implemented tension, so the apron that is socketed on the cushion rubber supporting plate can only rely on the elasticity of self to realize certain tension.If the apron of socket is loose excessively, will produce the smooth phenomenon of apron, the gripping effect to sliver in drafting process will reduce, thereby influences yarn quality; If the apron tension of socket will make apron rotate underaction, produce " throwing switch " phenomenon, like this, also can have a negative impact to yarn quality.And for the apron of degree of tightness appropriateness, use after a period of time at it, also can produce tension force fatigue, it is lax apron to occur, causes apron smooth.

The utility model content

Sell but the purpose of this utility model just provides on a kind of regular jaw of elastic tension apron,, thereby reach the duty that apron is operated steadily, guarantee yarn quality so that the apron of socket on it can remain due tensile force.

Sell but the utility model is achieved in that on a kind of regular jaw of elastic tension apron, be connected to the cushion rubber supporting plate respectively on the both sides of bracing frame bottom, institute's improvements are to be connected to elastic spring on the cushion rubber supporting plate.

The utility model is by being provided with elastic spring on the cushion rubber supporting plate of selling on the regular jaw, form on a kind of regular jaw of belt leather circle strainer to sell.Under the effect of this apron strainer, the apron of institute's socket is remained under the tensioning state, reach thus and eliminate the purpose that apron is smooth and apron is operated steadily, like this, apron can be consistent substantially to the gripping effect of sliver in drafting process, has guaranteed yarn quality thus.

Because what the apron strainer in the utility model applied is a kind of elastic anchorage force, thereby just can reduce original in the too high index request in apron elasticity aspect, the corresponding acquisition cost that reduces apron.Simultaneously because this apron strainer can the tired and apron that form of tension force is lax to have certain compensating action to occurring, but thereby the service life that makes apron also proper extension.

The utility model is suitable for selling on the regular jaw of different in width, on the upper leather collar pin of other types, also can use, and all applicable in the yarn drafting system on Speed frames and fine spining machine.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1, Fig. 2 are the structural representations of two kinds of implementations of the utility model.

The specific embodiment

The utility model includes several major parts such as bracing frame 1, cushion rubber supporting plate 2 and apron strainer, and cushion rubber supporting plate 2 is tapped at the both sides of bracing frame 1 bottom, and bracing frame 1 can keep original structure constant.

Elastic spring 4 as the apron strainer, its a kind of fixed form is to have caulking groove 3 on cushion rubber supporting plate 2 as shown in Figure 1, and the bottom interlocking of elastic spring 4 is in caulking groove 3, the upper end of elastic spring 4 exceeds the upper edge of cushion rubber supporting plate 2, to form the elastic support points to apron.Caulking groove 3 is preferably opened the surperficial center position at two cushion rubber supporting plates 2, and the bottom bending of elastic spring 4 can be rabbeted in the caulking groove 3 of cushion rubber supporting plate 2 so more securely.The T template shape of the top of elastic spring 4 for stretching obliquely, its upper end exceeds the upper edge of cushion rubber supporting plate 2, to form the resiliency supported to institute's socket apron.

Among Fig. 1, two journal stirrups can be set, can play position-limiting action to the apron of socket like this, thereby prevent apron sideslip or slippage in two corners of elastic spring 4 upper ends.

In addition, can establish a horizontal palm 5, so just the caulking groove form of a notch can be become caulking groove form, correspondingly, the bottom of elastic spring 4 also is bent into the following bending of two correspondences for the slit shape notch that two next-door neighbours are arranged at the notch place of caulking groove 3.Like this, rabbet again in this caulking groove 3, will make the firm degree of interlocking of elastic spring 4 that tangible enhancing is arranged.

The another kind of fixed form of elastic spring 4 is that the lower end with elastic spring 4 is made for the draw-in groove form as shown in Figure 2, and the top that is connected to cushion rubber supporting plate 2 is upright along last, stands in after the top bending of elastic spring 4 on the plate face of cushion rubber supporting plate 2.The width of the widened section on elastic spring 4 tops is suitable with the width of apron.In this implementation, what the apron of socket was played position-limiting action is at the made journal stirrup in both sides, two cushion rubber supporting plates, 2 upper edge.

Certainly, the utility model also can adopt other multiple modes that elastic spring 4 is fixedly connected on the cushion rubber supporting plate 2.

Claims

But 1, sell on a kind of regular jaw of elastic tension apron, be connected to cushion rubber supporting plate (2) respectively, it is characterized in that on cushion rubber supporting plate (2), being connected to elastic spring (4) on the both sides of bracing frame (1) bottom.
But 2, sell on the regular jaw of elastic tension apron according to claim 1, it is characterized in that having caulking groove (3) on cushion rubber supporting plate (2), the bottom interlocking of elastic spring (4) is in caulking groove, and the upper end of elastic spring exceeds the upper edge of cushion rubber supporting plate (2).
