It should be noted that, after the end cap 31 is screwed, the end cap 31 only covers the portion of the wire passing opening 21, in other words, at least a portion of the wire passing opening 21 needs to be exposed for overflow.

In this scheme, set up plug connector 32 on end cover 31, the aim at, when taking off end cover 31, can take out together with plug connector 32, thereby need not to carry out the operation of getting plug connector 32 in addition, and install plug connector 32 on end cover 31 with pivoted mode, and set up the purpose of the slot 23 that extends along the axial of sizing tube 2 on sizing tube 2 inner wall, drive plug connector 32 and rotate together when avoiding rotatory end cover 31, because perforation 331 is set up on plug connector 32, after the thread passed perforation 331, if end cover 31 rotation can drive plug connector 32 rotation, perforation 331 also corresponding emergence rotation this moment, the thread that passes perforation 331 will also rotate this moment, and then make the thread twist together in perforation 331 department, follow-up thread just can't normally be pulled forward. So in this scheme, rotate the plug connector 32 and set up on end cover 31 to guarantee that plug connector 32 can advance end cover 31 and take place relative rotation, and set up slot 23 on sizing tube 2, in order to carry out circumference location to plug connector 32, when making end cover 31 rotatory, plug connector 32 does not rotate, guarantees that the axial direction of perforation 331 remains unchanged.

As shown in fig. 5, the plug 32 includes two vertically disposed plug rods 321, and two slots 23 are correspondingly formed on two side walls of the sizing pipe 2 for respectively inserting the two plug rods 321; the plug connector 32 further comprises a cross beam 322 arranged between the tops of the two plug rods 321, the cross beam 322 and the two plug rods 321 are integrally formed to form a U-shaped structure, the cross beam 322 is rotatably connected to the axle center of the end cover 31 through an axle pin 323, the axle pin 323 is specifically fixedly arranged in the center of the cross beam 322, the axle pin 323 is rotatably connected to the axle center of the end cover 31, and the axle pin 323 can rotate in the circumferential direction relative to the end cover 31 and is kept positioned in the axial direction.

The ring member 33 is disposed on the plug member 32, specifically, the ring member 33 is disposed between the two plug rods 321, and the ring member 33 is fixedly connected with the two plug rods 321 through the connecting rods 34 on two sides. And the axial direction of the annular ring 33 is parallel to the connecting line direction of the two wire passing ports 21.

Since the yarns need to be dried in the later stage after sizing, in this embodiment, the apparatus further includes a drying mechanism for pre-drying the yarns to reduce the moisture content of the yarns and accelerate the subsequent drying time.

Specifically, as shown in fig. 3, the drying mechanism includes a pipe with two open ends for the spinning line to pass through, and an electric heating element is arranged in the pipe, so that the electric heating element is arranged in the pipe, and the purpose of concentrating the heat generated by the electric heating element into the pipe as much as possible is achieved, so that the spinning line can be well heated and dried when passing through the pipe.

Specifically, the pipe is disposed vertically, so that the yarn may pass through the pipe substantially vertically, and in this embodiment, the bottom of the pipe is provided with the third guide wheel 9, and the pipe is located between the second guide wheel 132 and the third guide wheel 9.

Because the pipe fitting possesses certain length, and its pipe diameter is less, want to penetrate the spinning line from pipe fitting one end, the other end wears out, and the operation is got up comparatively inconveniently, so this embodiment does further improvement: referring to fig. 3 and 8, the pipe fitting includes an inner pipe 51 which is kept in position and an outer pipe 52 which is sleeved on the inner pipe 51 and can rotate circumferentially relative to the inner pipe 51, and specifically, the inner pipe 51 is fixed on the casing 1 and kept fixed; a chute 512 is circumferentially formed on the outer wall of the inner tube 51; outer tube 52 is slidably mounted within chute 512 such that outer tube 52 is circumferentially rotatable relative to inner tube 51 and axially maintained in position.

The inner tube 51 has a first opening 511 extending axially along the inner tube 51, and the outer tube 52 has a second opening 521 extending axially along the outer tube 52, and it will be appreciated that the outer tube 52 cannot escape radially along the inner tube 51 through the second opening 521.

As shown in fig. 8, outer tube 52 rotates relative to inner tube 51 to create a first position in which first opening 511 and second opening 521 overlap for threadlines to enter and exit inner tube 51; in the second position, first opening 511 and second opening 521 are offset, and the wall of outer tube 52 covers first opening 511.

Thus, when the thread needs to be threaded into the pipe (inner pipe 51), the outer pipe 52 can be rotated to a first position, where the first opening 511 and the second opening 521 are overlapped, where the first opening 511 and the second opening 521 are integrally equivalent to the opening of one pipe, where the thread can be horizontally moved into the pipe from the opening, and then the outer pipe 52 can be rotated to a second position, where the pipe wall of the outer pipe 52 covers the first opening 511, so as to prevent a large amount of heat from escaping from the first opening 511 during subsequent drying.

Wherein the electric heating element can be an electric heating wire (not shown in the figure) which is embedded in the wall of the inner tube 51; it is of course also possible to embed it in the wall of the outer tube 52, or to embed heating wires in both the inner tube 51 and the wall of the outer tube 52, although it is most preferable to embed it in the wall of the inner tube 51, since the inner tube 51 is kept stationary.

The temperature measuring member 61 here may be a probe type temperature sensor.

As for the specific installation position of the temperature measuring member 61, there can be the following two modes:

the first way is: the temperature measuring probe of the temperature measuring piece 61 extends into the inner pipe 51 by fixing the temperature measuring probe on the inner pipe 51, and the disadvantage of the mode is that the temperature measuring piece 61 can only be arranged at the pipe opening of the inner pipe 51 due to the existence of the outer pipe 52, so that interference is not caused to the outer pipe 52, and the pipe opening is relatively close to the external environment, so that the temperature is relatively low, and the temperature measuring effect is relatively general. (this embodiment is not shown in the drawings)

The second way is: as shown in fig. 8, the temperature measuring probe is fixed on the outer tube 52, and the outer tube 52 needs to rotate, so that the temperature measuring probe which does not interfere with the temperature measuring piece 61 when the outer tube 52 rotates needs to be considered; therefore, a temperature measuring tube 62 communicating with the inside of the outer tube 52 is provided at the middle position of the outer tube 52; the temperature measuring member 61 is fixedly installed on the temperature measuring tube 62, wherein the temperature measuring probe of the temperature measuring member 61 is located in the temperature measuring tube 62, and when the outer tube 52 rotates to the second position, the inner end tube opening of the temperature measuring tube 62 is located at the first opening 511, in this way, the temperature measuring area is relatively close to the middle area of the tube, the temperature measuring effect is better, during temperature measurement, heat in the tube can be transferred into the temperature measuring tube 62, and then detected by the temperature measuring member 61 in the temperature measuring tube 62, in order to reduce the temperature in the tube to be lost through the outer end tube opening of the temperature measuring tube 62, in this embodiment, the temperature measuring member 61 is installed on the temperature measuring tube 62 through the flange joint. The drawings of this embodiment show a second embodiment.

As shown in fig. 1, the drying mechanism further includes a driving assembly for driving the outer tube 52 to rotate relative to the inner tube 51, the driving assembly includes a toothed ring section 74 disposed on the outer wall of the outer tube 52 and circumferentially along the outer tube 52, a rack section 711 engaged with the toothed ring section 74, and a power member 73 for driving the rack section 711 to translate, wherein the toothed ring section 74 is disconnected at the second opening 521 so that the toothed ring section 74 does not block the second opening 521.

Specifically, sliding sleeves 72 are fixedly installed on two sides of the casing 1, sliding strips 71 capable of sliding horizontally relative to the sliding sleeves 72 are arranged in the sliding sleeves 72, the sliding strips 71 are horizontally arranged, rack segments 711 are arranged on the side walls of the sliding strips 71, a power piece 73 is installed on the casing 1 and connected with the sliding strips 71 and used for driving the sliding tables to horizontally slide, and then the rack segments 711 are driven to horizontally slide so as to drive tooth ring segments 74 to rotate, and finally the outer pipe 52 is driven to rotate relative to the inner pipe 51. The power member 73 may be an air cylinder, a hydraulic cylinder, an electric cylinder, etc., and may be any other linear module, which is not limited herein.

In order to adapt to the embodiment of sizing and drying of a plurality of spinning wires, the device comprises a plurality of pipe fittings, all pipe fittings are arranged side by side, wherein the outer walls of all outer pipes 52 are provided with toothed ring sections 74, and a rack section 711 meshed with each toothed ring section 74 is arranged on a sliding strip 71 corresponding to each toothed ring section 74, so that the sliding strip 71 can slide to drive all outer pipes 52 to rotate simultaneously, thereby saving power sources, accelerating efficiency and avoiding the need of rotating the outer pipes 52 one by one.

In order to further ensure the uniformity of the slurry in the slurry tank 11 and prevent precipitation, in this embodiment, as shown in fig. 2, a stirring mechanism for stirring the slurry tank 11 is disposed in the slurry tank 11, specifically: the inner wall of the slurry tank 11 is circular, the stirring mechanism comprises a motor, a rotating shaft 81, a plurality of stirring rods 82 arranged on the rotating shaft 81, and scraping blades 83 arranged at one end of the stirring rods 82 away from the rotating shaft 81 and propped against the inner wall of the slurry tank 11, wherein the motor drives the rotating shaft 81 to rotate so as to drive the stirring rods 82 to rotate for stirring, and meanwhile, the stirring rods 82 drive the scraping blades 83 to rotate along the circumferential direction of the slurry tank 11 so as to scrape slurry precipitates attached to the inner wall of the slurry tank 11.
