Abstract

The utility model discloses a regulating device installed on spinning machine traction mechanism, comprising an upper positioning cap, a spring, a lower positioning cap, and a pressure rod. The cap base of the upper positioning cap is provided with a hole which can be sleeved on a convex base of a traction mechanism. The cap body extends into the hollow part of the upper part of the spring. The spring respectively grinds the upper and lower positioning caps on the convex base of the traction device and the pressure rod. A hole which can be extended in by a tooling is arranged on the convex base of the traction device. One end of the pressure rod which is remote from the positioning cap is fixed together with an upper roller of the spinning machine. After assembling the regulating device, a central axis of the hole which is on the cap body of the upper positioning drifts a certain distance compared with the central axis of the hole of the convex base. When the tooling extends into the hole of the cap body of the upper positioning cap from the convex base, rolling and adjusting, the cap body of the upper positioning cap also generates eccentric drive with the comparative convex base. Through the adjustment of the upper roller of the spinning machine, which generates by the pressure rod driven by the spring, the fine adjustment of the degree of parallelization between the upper and lower rollers of the spinning machine is realized.

The specific embodiment

Now, a kind of adjusting device that is installed in the spinning machine draw-gear of the utility model is described in further detail in conjunction with Figure of description.

As shown in figures 1 and 3, the adjusting device 2 of the utility model spinning machine draw-gear 1 comprises positioning cap 20, spring 22, following positioning cap 23 and pressure rod 26.Consult Fig. 5 and Fig. 6 simultaneously, last positioning cap 20 comprises cap seat 201 and cap body 202, and cap seat 201 is provided with a hole 203 that can be placed on the draw-gear 1 protruding seat 12.Cap body 202 stretches into the hollow space of spring 22 upper ends, and cap body 202 is provided with a hole 204 that can supply bar-shaped adjustment means (not shown) to stretch into.

Following positioning cap 23 is located at the side near pressure rod 26, and its cap body 230 stretches into the hollow space of spring 22 lower ends.Spring 22 withstands on upper and lower positioning cap 20,23 respectively on the protruding seat 12 and pressure rod 26 of draw-gear 1.The protruding seat 12 of draw-gear 1 is provided with a hole 14 that can supply this adjustment means to stretch into.

Consult Fig. 4 simultaneously, pressure rod 26 is fixed as one away from the top roller 30 of following positioning cap 23 1 ends and spinning machine.There are a connecting rod 301, the forearm 260 of pressure rod 26 promptly to fixedly connected one in the middle of the top roller 30 with the connecting rod 301 of top roller 30.

After described adjusting device 2 assemblings are finished, the central axis skew certain distance in the hole 14 of the protruding relatively seat of the central axis in the hole 204 on the last positioning cap 20 cap bodies 202 12, the off-centre setting between the hole 203 that can be by making positioning cap 20 cap seats 201 and the hole 204 of its cap body 202 is realized (as shown in Figure 4 and Figure 5).The degree of eccentricity between the hole 203 of cap seat 201 and the hole 204 of its cap body 202 can be controlled in 0.5～0.75mm, and the best is 0.65～0.7mm.The actual employing of the utility model 0.7mm.

The hole 204 of last positioning cap 20 cap bodies 202 can be square opening or other shape, can insert via hole 14 on the draw-gear 1 protruding seat 12 and 203 backs, the hole on the last positioning cap 20 cap seats 201 for bar-shaped adjustment instrument and wherein rotate adjusting accordingly.This bar-shaped adjustment instrument produces eccentric corrective action by 204 pairs of springs in hole 22 of last positioning cap 20 cap bodies 202, makes pressure rod 26 produce the micrometric displacement of horizontal direction, thereby realizes the regulating action to the depth of parallelism between spinning machine top roller 30 and the bottom roll 32.

Adjusting device 2 also comprises push rod 24, regulator board 27 and the pressure block 28 that is connected on the draw-gear 1.Wherein, push rod 24 vertically passes a locating piece 25 that is fixed on the pressure rod 26, and lower end and regulator board 27 1 ends offset, and following positioning cap 23 is pressed in the upper end of push rod 24 downwards, and pressure block 28 offsets with the end of regulator board 27 away from push rod 24.The pressure that spring 22 is applied to down on the positioning cap 23 is delivered on the pressure rod 26, and the top roller 30 of 26 pairs of spinning machines of pressure rod is exerted pressure to reach the regulating action to spinning machine top roller 30.

The utility model adjusting device 2 adopts the pressure block 28 of seven limit bodies, makes it can realize fourth gear pressure regulation level, thereby increases by one grade of pressure regulation level that makes draw-gear 1 be in half depressurization phase.

After adjusting device 1 assembling of the present utility model is finished, the central axis skew certain displacement in the hole 14 of the protruding relatively seat 12 of the central axis in the hole 204 on the last positioning cap 20 cap bodies 202, make when adjustment means in the hole 14 of protruding seat 12 stretches to the hole 204 of positioning cap 20 cap bodies 202 during the rotation adjusting, eccentric rotary takes place in the also protruding relatively thereupon seat 12 of last positioning cap 20 cap bodies 202, and by spring 22 drive pressure rods 26, make it to produce moving of horizontal direction, thereby can regulate spinning machine top roller 30, realization remains within the best controlled critical field yarn quality of whole spinning machine to the accurate adjustment of the depth of parallelism between spinning machine top roller 30 and the bottom roll 32.

The pressure block 28 that the utility model adopts is seven limit bodies, and the hexahedron pressure block of prior art makes this adjusting device 2 can realize fourth gear pressure regulation level before comparing, and increases by one grade of pressure regulation level that makes draw-gear be in half depressurization phase.Be in half depressurization phase when front spring is not worked, can make to improve 20～30% the service life of front spring.Because the front spring release is complete, also help unclamping by the associated acrylonitrile-butadiene rubber roller of upper and lower roller, reduced the bonding of roller surface to yarn, when restarting spinning machine, just significantly reduced broken yarn phenomenon because of boning and cause with the roller surface.

The utility model provides the adjusting device that is installed in the spinning machine draw-gear, can realize between the upper and lower roller of spinning machine, the especially meticulous adjusting of the depth of parallelism between front upper roller and the preceding bottom roll, thus guaranteed the spinning machine resultant yarn evenly and uniformity.

And, this adjusting device has increased the design of one and half depressurization phases to the pressure block of being located at its arm front end, make its corresponding spring when not working, can be in half depressurization phase, thereby can improve its service life, minimizing is changed the frequency of spring because of producing to stop work midway, thereby the production efficiency of being improved, and can corresponding saving cost.
