Technical field

The utility model relates to a kind of pneumatic aggregation apparatus of yarn of compact spinning machine, especially relates to the grid ring tension mechanism of the pneumatic aggregation apparatus of a kind of yarn.Belong to textile machine and accessory technical field.

Background technology

Compact spinning machine has increased a filoplume polymerization mechanism at spinning triangular zone, and filoplume is assembled mechanism and is made up of negative pressure pipe and the grid ring that is enclosed within the densely covered pore of negative pressure pipe upper surface.Have a plurality of air-flow gathering sills on the tube wall of negative pressure pipe one side, a plurality of grid ring are set on each air-flow gathering sill of negative pressure pipe, and the corresponding one thread of each air-flow gathering sill.When the negative pressure pipe communicates with negative pressure source, yarn is attached on the grid ring filoplume on the yarn during by grid ring, in pipe under the effect of negative pressure, the filoplume of yarn is along with the rotation of grid ring, certainly in the sth. made by twisting process filoplume is being wrapped on the yarn, reduce the filoplume of yam surface significantly, make yam surface clear smooth, increase the intensity of yarn.Owing to the influence that is subjected to reasons such as material, manufacturing, the girth of grid ring is difficult to guarantee that the grid ring in therefore rotating with roller is supported by a tension mechanism, makes the grid ring that is sleeved on the negative pressure pipe to keep constant tension force by tension mechanism.But present disclosed strainer is made of tension force bearing, spring and tension rail.Be provided with spring between tension force bearing and the tension rail, adjust the tension force of grid ring by spring, but limited because of the ABRASION RESISTANCE of tension rail material and top coating, grid ring turns round after a period of time in the above, because of the friction grooving, influence the normal running of grid ring on the tension rail.The tension bracket that need more renew has increased user's use cost.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of ABRASION RESISTANCE that can improve tension bracket and grid ring contact site is provided, with the grid ring tension mechanism of the pneumatic aggregation apparatus of yarn that prolongs tension bracket service life.

The purpose of this utility model is achieved in that a kind of grid ring tension mechanism, described tension mechanism comprises base, tension bracket and spring, the described base top guide ledges that is provided with protruding upward, button pawl and supporting guide pillar, described guide ledges is arranged on the centre of base top, supporting guide pillar and button pawl have two, be symmetricly set on the right and left of guide ledges, and the supporting guide pillar places between button pawl and the guide ledges, described tension bracket profile is similar to " ∩ " shape, the tension bracket inboard is provided with ring-shaped step, form cavity between ring-shaped step and the tension bracket inwall, the position that contacts with grid ring on the tension bracket outer wall is equipped with wear plate, the wear plate profile also is similar to " ∩ " shape

Described tension bracket places the base top, and the button of two on base dog clutch is on the ring-shaped step of described cavity bottom, and spring is nested with on the supporting guide pillar on the base, and the spring bottom withstands on the base, and the spring top withstands on described cavity top.

The utility model grid ring tension mechanism, described tension bracket root edge forms ring-shaped step to in-flanges in the tension bracket inboard.

Tension bracket of the present utility model is connected on the base, and wear plate is embedded in the tension bracket surface, be provided with spring between tension bracket and the base again, can regulate the tensile force of grid ring by spring, wear plate has solved the tension bracket grooving that the tension bracket surface causes because of friction and the wearing and tearing of tension bracket overlay coating, improve the ABRASION RESISTANCE of tension bracket greatly, improved the service life of tension bracket.

Fig. 2 is the vertical section structure schematic diagram of Fig. 1.

Fig. 3 is the cross section vertical section structure schematic diagram at Fig. 1 spring place.

Fig. 4 is that the utility model grid ring tension mechanism is installed in the structural representation on the negative pressure pipe.

Among the figure: negative pressure pipe 1, driving roller 2, grid ring 3, base 4, tension bracket 5, button pawl 6, supporting guide pillar 7, spring 8, wear plate 9, boss 10, guide ledges 11; Ring-shaped step 5.1, cavity 5.2.

The specific embodiment

Referring to Fig. 1～3, the grid ring tension mechanism of the pneumatic aggregation apparatus of yarn that the utility model is related mainly is made up of base 4, tension bracket 5 and spring 8.Described base 4 tops guide ledges 11, button pawl 6, supporting guide pillar 7 and the boss 10 of being provided with protruding upward.Wherein: guide ledges 11 is arranged on the centre at base 4 tops, and supporting guide pillar 7 and button pawl 6 have two, are symmetricly set on the right and left of guide ledges 11, and supporting guide pillar 7 places between button pawl 6 and the guide ledges 11.Described boss 10 also has two, is symmetricly set on the left and right both sides of base 4.

Described tension bracket 5 profiles are similar to " ∩ " shape, tension bracket 5 root edges form ring-shaped steps 5.1 to in-flanges in tension bracket 5 inboards, form cavity 5.2 between ring-shaped step 5.1 and tension bracket 5 inwalls, the position that contacts with grid ring 3 on tension bracket 5 outer walls is equipped with wear plate 9, and wear plate 9 profiles also are similar to " ∩ " shape.

Described tension bracket 5 places base 4 tops, and the button of two on the base 4 pawl 6 is buckled on the ring-shaped step 5.1 of described cavity 5.2 bottoms, and spring 8 is nested with on the supporting guide pillar 7 on the base 4, and spring 8 bottoms withstand on the base 4, and spring 8 tops withstand on described cavity 5.2 tops.

When button pawl 6 was buckled on the ring-shaped step 5.1 of cavity 5.2 bottoms, be the maximum of tension mechanism to top offset this moment, when phase left-hand thread pawl 5 is run into cavity 5.2 tops, is the maximum of tension mechanism to bottom offset at this moment.Under guide ledges 11 guiding, tension mechanism has reduced the beat of tension bracket toward both sides in the process that moves up and down, and helps bringing into play the efficient of spring.Guarantee at the constant-tension of tension mechanism on same direction.Make the grid ring operation more steady.Ring-shaped step in tension bracket bottom can prevent that grid ring breaks away from tension mechanism at the volley, and the wear plate of the surperficial setting-in of tension bracket has guaranteed service life of tension bracket.Simultaneously on base, increased boss 10, increased the degree of depth that is screwed into of screw, can be better fixing tension mechanism.

Referring to Fig. 4, Fig. 4 is that the utility model grid ring tension mechanism is installed in the structural representation on the negative pressure pipe.As can be seen from Figure 4, the base 4 of the utility model grid ring tension mechanism is installed in the mounting groove of negative pressure pipe 1, cavity in the negative pressure pipe 1 communicates with negative pressure source by air entry, grid ring 3 is sleeved on negative pressure pipe 1 and the tension mechanism and is positioned at each air-flow guide groove place, drives the rotation of roller 2 by pressurization roller clamping grid ring 3.
