Abstract

The utility model relates to a double lower rubber ring tension bracket used on a spinning machine, the structure of the tension bracket comprises a bracket and a tension roller, wherein, the middle section of the tension roller is blocked in a groove of the bracket, and two ends of the tension roller extend out of the side of the bracket. The tension bracket realizes that a novel structure of tensioning two rubber rings is supported on the bracket, so as to be convenient for cleaning and maintaining the rubber rings. Three lower rubber ring tension brackets are only crossed on each section of pull rod, the consumption of the parts is reduced, the dismounting operation procedure of replacing the tension bracket is obviously simplified, and the working efficiency is improved. The tension bracket also realizes the rolling friction of the rubber rings and the tension roller, not only reduces the attrition rate of the tension roller, but also improves the service lives of the tension bracket and the rubber rings, saves the production cost, and is favorable to improving the economic benefit of enterprises.

Description

Two apron tension framves down

Technical field

The utility model relates to the parts on a kind of fine spining machine of weaving, specifically a kind of two apron tension framves down.

Background technology

The parts that the following apron tension frame that uses on the present weaving fine spining machine is an integral casting forming promptly connect a backing roll in the front portion of carriage by sidewall paneling, and the width of backing roll is identical with the width of carriage.All corresponding being socketed on the backing roll of a following apron tension frame of each cushion rubber in socket on the roller.Torsion spring is installed and has pull bar to pass in the carriage of following apron tension frame, its effect is exactly a height of adjusting backing roll by torsion spring at any time, to make it to strain cushion rubber, allows cushion rubber be adjacent to roller, successfully rotates thereby be convenient to roller drive cushion rubber.

For avoiding influencing spinning because of long-pending flower stuck phenomenon occurring, the rotating part of fine spining machine comprises that roller and cushion rubber etc. all need to carry out frequently cleaning.Because existing apron tension frame down all is the configuration structure of one one cushion rubber, therefore when carrying out the cleaning of cushion rubber, operates comparatively loaded down with trivial details.

In addition, on the fine spining machine each cuts on the pull bar all that cross-under has six following apron tension framves, if one of them down apron tension frame need to change, just need the replacing that six dismounting action just can be finished a following apron tension frame, action repeats many, operates comparatively loaded down with trivial details.

The utility model content

The purpose of this utility model just provides a kind of two apron tension frame down, with the workload that alleviates the cushion rubber cleaning and change, increases work efficiency.

The utility model is achieved in that a kind of two apron tension frame down, and this tension bracket includes carriage and jockey pulley, and the stage casing of jockey pulley is connected in the carriage groove, the side of its protruding carriage in two ends.

The utility model has changed the existing structure of one one cushion rubber of apron tension frame down, separates with the structure of carriage with mutual clamping by jockey pulley to cooperate, and has realized can supporting on a carriage brand new of two cushion rubbers of tensioning.Its good effect, the one, point the hook that makes progress with two and can take off jockey pulley very easily, and after extracting this jockey pulley out, can carry out cleaning two cushion rubbers that are socketed on this roller, therefore operation is easy to some extent, is easier to cleaning; The 2nd, owing to realized the support and the tensioning of two cushion rubbers, therefore on each section pull bar, just only need three this apron tension framves down of cross-under to get final product, make the parts consumption reduce thus, and as long as three dismounting action can be finished the replacing of a following apron tension frame, operating procedure is obviously simplified, and operating efficiency greatly improves.

The utility model also can be realized like this: on the basis of said structure, be socketed with bearing on two overhanging ends of jockey pulley.Its effect is exactly the rolling friction that realizes between cushion rubber and jockey pulley, greatly reduce the frictional resistance between cushion rubber and the jockey pulley and the running resistance of cushion rubber thus, both lowered the degree of wear of jockey pulley, improved the service life of tension bracket and cushion rubber again, save production cost, helped to improve economic benefit of enterprises.

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

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the following apron tension frame of this pair includes carriage 1 and jockey pulley 2, on the two side of carriage 1 back seat groove perforate is arranged, in order to the cross-under pull bar; The back seat groove is interior in order to torsion spring to be set.On the lead arm of carriage 1, have the draw-in groove of upper shed, in order to the clamping jockey pulley.Jockey pulley 2 is the bodies of rod that the middle part is thin, two ends are thick, and the thin segment at its middle part is connected in the groove of carriage 1 lead arm, and two sides of the thick section protruding carriage 1 at its two ends are in order to two adjacent cushion rubbers of cross-under socket on roller.

On the basis of said structure, the utility model is bearing 3 of each socket on two overhanging ends of jockey pulley 2 also, has realized the rolling friction between cushion rubber and jockey pulley thus.

Claims

1, a kind of two apron tension frame down is characterized in that this tension bracket includes carriage (1) and jockey pulley (2), and the stage casing of jockey pulley (2) is connected in the carriage groove, the side of the protruding carriage in two ends.

2, two apron tension frame down according to claim 1 is characterized in that being socketed with bearing (3) on two overhanging ends of jockey pulley (2).
