Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The following provides a more detailed description of the present invention with reference to specific embodiments,

fig. 2 shows a schematic structural diagram of the middle false twisting tangential belt transmission mechanism of the present invention, which mainly comprises a driving wheel 1, a guide wheel 2, a tension wheel 3, a false twister driving wheel 4, a switch wheel 5, an annular belt 6, etc. Wherein, action wheel 1 and take-up pulley 3 arrange respectively in the both ends of annular belt 6. The guide wheel 2, the false twister driving wheel 4 and the switch wheel 5 are all attached to the annular belt 6 all the time to transmit the driving force.

FIG. 3 shows a schematic structural view of the first embodiment of the deviation rectifying part in the false twist tangential belt transmission mechanism of the present invention, it can be seen that the deviation rectifying part 7 is arranged at the upstream 30-50mm of the false twister driving wheel 4, and it is composed of two parts of the cylinder 72 which is displaced along the axial direction thereof by the adjusting roller set 71 and the driving adjusting roller set 71. Wherein, the cylinder 72 is fixed with the frame of the elasticizer. The adjustment roller group 71 includes a support frame 711, an upper adjustment roller 712, and a lower adjustment roller 713. The upper and

lower adjustment rollers

712 and 713 are rotatably fixed to the support frame 711 in parallel with each other and elastically pressed against the upper and lower surfaces of the endless belt 6, respectively, to be opposed to each other. Therefore, in the running process of the elasticizer, the axial position of the adjusting roller group 71 can be changed according to the actual deviation of the annular belt 6, so that the annular belt 6 can be correspondingly adjusted under the action of the friction force of the adjusting roller group 71, the moving directionality of the annular belt 6 is ensured, the phenomenon of excessive abrasion caused by the offset of the annular belt relative to other driving wheels (comprising the driving wheel 1, the guide wheel 2, the tension wheel 3, the false twister driving wheel 4, the switch wheel 5 and the like) is avoided, and the service life of the elasticizer is ensured.

In addition, in order to facilitate adjustment of the relative position and the biasing direction of the cylinder 72, the following design may be referred to: the cylinder 72 is directly fixed on the mounting seat, and the mounting seat is connected with dismantling of the elasticizer frame by means of bolts, and correspondingly, strip waist-shaped holes are formed in the bottoms of the four corners of the mounting seat so that the bolts can penetrate into the holes.

Here, the power element for driving the adjustment roller group 71 may be a linear motor, a hydraulic cylinder, or the like, as the case may be, in addition to the above-described air cylinder 72.

As a further refinement of the structure of the false twisting tangential belt transmission mechanism, the upper adjustment roller 712 includes a central rotating shaft 7121, a rotating drum 7122, and a bearing 7123 sleeved on the central rotating shaft 7121. The drum 7122 is rotatably sleeved on the central shaft 7121 by a bearing 7123. Thus, not only is the assembly and molding of the upper adjustment roller 712 facilitated and the production and manufacturing costs reduced, but also, more importantly, the molded upper adjustment roller 712 has good rotational smoothness and prevents the occurrence of rapid wear due to sliding friction between the endless belt 6 and the upper adjustment roller 712.

Similarly, the lower adjustment roller 713 may be designed and manufactured with reference to the upper adjustment roller 712.

Fig. 4 shows a schematic structural diagram of a second embodiment of the deviation rectifying part in the false twist tangential belt transmission mechanism of the present invention, which is different from the first embodiment in that: an anti-slip sleeve 7124 is additionally arranged and sleeved and fixed on the peripheral side wall of the rotary drum 7122. Generally, the material of the anti-slip sleeve 7124 is butadiene rubber. In the actual operation process, the anti-slip sleeve 7124 can form an elastic buffer layer between the endless belt 6 and the upper adjusting roller 712, and the friction coefficient is increased, so that the displacement adjusting process of the endless belt 6 is smoother. In addition, it is known that the butadiene rubber has more excellent wear resistance and self-lubricity, so that the wear rate of the outer side wall of the upper adjusting roller 712 is reduced to a certain extent, the service life of the roller is prolonged, and the later maintenance frequency and cost are reduced.

Furthermore, annular abutting flanges 71241 (shown in fig. 5) may be provided at both ends of the slip-preventing sleeve 7124, so as to effectively prevent the offset of the endless belt 6 with respect to the upper steering roller 712 due to an accident during the actual operation, and ensure the operation directionality thereof. In addition, in special cases, the displacement adjustment of the endless belt 6 can be achieved by pushing the side wall of the endless belt 6 by the annular abutting flange 71241.

Furthermore, the deviation rectifying portion 7 may be additionally provided with a displacement sensor 73 (as shown in fig. 2) and a controller. The specific arrangement may be performed with reference to: the controller is coupled to both the displacement sensor 73 and a power element, such as the air cylinder 72. The displacement sensor 73 is arranged at the downstream side of the adjusting roller group 71 by 20-30cm, detects the offset of the endless belt 6 in real time, feeds back data to the controller in time, and sends an action signal to the power element when the data exceeds a preset standard value in the controller. Therefore, automation and intellectualization of the position adjustment of the annular belt 6 can be realized, the timeliness of the adjustment is improved, manual intervention is not needed in the whole process, and the labor cost is reduced.

In order to improve the detection precision of the offset of the endless belt 6 and provide reliable data reference for subsequent intelligent control and adjustment, magnetic stripes (not shown in the figure) can be arranged 5-10mm inwards from the two side edges of the endless belt 6. It should be noted that the displacement sensor 73 is correspondingly configured as an inductive displacement sensor associated with the magnetic strip.

Finally, in order to avoid the abrasion of the magnetic strips, improve the service life of the magnetic strips as much as possible and reduce the later maintenance cost, avoidance sunken grooves can be formed in the positions corresponding to the magnetic strips on the driving wheel 1, the guide wheel 2, the tension wheel 3, the false twister driving wheel 4, the switch wheel 5 and the adjusting roller group 71. As shown in FIG. 2, the escape sinker 41 provided on the false twister drive wheel 4 is disposed near the end thereof and preferably controlled to have a depth of 3 to 5 mm. The arrangement mode of the avoiding sinking grooves on the driving wheel 1, the guide wheel 2, the tension wheel 3, the switch wheel 5 and the adjusting roller group 71 can be analogized by referring to the false twister driving wheel 4.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
