Detailed Description
As shown in fig. 1-6, the fine fiber collecting device for textile production comprises a rinsing cylinder 1, wherein a liquid inlet 2 is arranged at the upper part of one side of the rinsing cylinder 1, a liquid outlet 3 is arranged at the lower part of one side of the rinsing cylinder 1, and a fiber collecting mechanism is arranged in the rinsing cylinder 1. The fiber collecting mechanism can be designed with the rinsing cylinder 1 in an integrated mode or independently, and the fiber collecting mechanism and the rinsing cylinder are matched for use. In other words, the fiber collecting mechanism can move to the rinsing cylinder 1 when the fibers in the rinsing cylinder 1 need to be cleaned; or a movable bracket can be independently arranged and pushed to the rinsing cylinder 1 through the movable bracket when in use. Of course, in order to facilitate the movement of the rinsing drum 1, the bottom of the rinsing drum 1 can also be provided with rollers 25 with brakes.
The fiber collecting mechanism comprises a vertical rotating shaft 4 arranged at the center of the rinsing cylinder 1, and the rotating shaft 4 is arranged on a supporting arm 5 above the supporting arm 5 rinsing cylinder 1 and is in running fit with the supporting arm 5. For the sake of illustration, the present invention takes an integrated design as an example, that is, the fiber collecting mechanism is disposed on the rinsing cylinder 1, and certainly in order not to affect the normal use of the rinsing cylinder 1, the supporting arm 5 is preferably not fixedly disposed, but as shown in fig. 1, an upright column 23 is disposed on the upper portion of the side of the rinsing cylinder 1 away from the liquid inlet 2, and one end of the supporting arm 5 away from the rotating shaft 4 is hinged with the upper end of the upright column 23. In order to adapt to different water level heights in the rinsing cylinder 1, the rotating shaft 4 is composed of an upper section and a lower section which are mutually sleeved, and the upper section and the lower section of the rotating shaft 4 are locked by a locking bolt 24 arranged on the side wall of the upper section.
The upper end and the driving motor 6 of pivot 4 are connected, can dismantle on the global of lower extreme and connect two at least collection boxes 7, collect box 7 and be rectangular form, and follow the radial extension of pivot 4. In the use, pivot 4 rotates, drives and collects box 7 motion, and then realizes the collection to the fibre.
As shown in fig. 2 to 4, the collecting box 7 includes a water-facing plate 8 and a string bag 9, and as will be understood, the water-facing plate 8 is a plate body facing the advancing direction of the collecting box 7 when the rotating shaft 4 rotates. The front and two end faces of the collecting box 7 are composed of water-facing plates 8, and the upper, lower and back sides of the collecting box 7 are composed of net bags 9. The positive 8 upper portions of meeting the water board of collecting box 7 are provided with along the collection mouth 10 that collects box 7 length direction and extend, be provided with the swing door 11 of looks adaptation in the collection mouth 10, the lower border of swing door 11 is articulated each other with the lower border of collecting mouth 10, and the articulated center is provided with reset torsion spring. A cleaning door 12 is arranged on the end face of the collecting box 7.
In the use process of the invention, when the number of floating fine fibers in the rinsing cylinder 1 is large, the driving motor 6 is turned on, the driving motor 6 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the collecting box 7 arranged at the lower end of the rotating shaft to rotate; the collection opening 10 of the collection box 7 is at the water level in the rinsing tank 1, as shown by the dashed line in fig. 4, i.e. the water level. Along with the rotation of the collecting box 7, the swinging door 11 at the collecting opening 10 is impacted by liquid and inclines towards the inside of the collecting box 7, at the moment, the collecting opening 10 is opened, the fine fibers floating on the water surface of the rinsing cylinder 1 can enter the collecting box 7, and the fine fibers are filtered through the net bag 9 of the collecting box 7 to be trapped in the collecting box 7. After the rotating shaft 4 stops rotating, the collecting box 7 does not rotate any more, and the swinging door 11 automatically resets under the action of the reset torsion spring, so that the collecting opening 10 is sealed, and the fibers collected in the collecting opening can be prevented from floating out again. Compared with the traditional manual collection mode, the automatic collecting device can greatly reduce the labor intensity and improve the collection efficiency, and is very convenient to use.
After the collecting box 7 is fully collected, in order to facilitate cleaning, the collecting box 7 should be conveniently taken down, that is, the collecting box 7 adopts detachable connection, the specific connection mode can be clamping connection, bolt connection and the like, and can also be as shown in fig. 2 and 5, one end of the collecting box 7 close to the rotating shaft 4 is provided with a short square rod 13, and the short square rod 13 is provided with a connecting disc 14. The lower extreme of pivot 4 is provided with connector 15, the quantity that corresponds collection box 7 on the side of connector 15 evenly is provided with a plurality of adapter sleeve 16, adapter sleeve 16 cooperatees with short square pole 13. The short square bar 13 is inserted into the connecting sleeve 16 and locked by the locking assembly.
The specific structure of the locking assembly is also many, for example, the locking assembly may be a pressing bolt arranged on the side wall of the connecting sleeve 16, but in order to further improve the stability of the connection, it is preferable that the locking assembly further includes, as shown in fig. 5, a plurality of press buckles uniformly arranged on the circumferential surface of the connecting sleeve 16, each press buckle includes a press plate 17, a first hinge seat 18 is arranged in the middle of the press plate 17, and a second hinge seat 19 is arranged on the connecting sleeve 16 corresponding to the first hinge seat 18. The first hinge base 18 and the second hinge base 19 are hinged to each other, and a compression torsion spring is arranged in the hinge center. One end of the pressing plate 17, which is close to the connecting disc 14 on the short square rod 13, is provided with a pressing head 20, and the pressing head 20 presses the connecting disc 14 under the elastic action of the pressing torsion spring to lock the short square rod 13 and the connecting sleeve 16.
In order to achieve a full fibre collection in the rinsing cylinder 1, the outer end of the collecting box 7 extends to the rim of the rinsing cylinder 1, so that a larger collecting surface is provided. In this case, however, the collecting box 7 is relatively inconvenient to mount and dismount due to its relatively long length, and for this reason, it is preferable that the connecting sleeve 16 is in a swingable form, in particular, it can swing and can form an effective support when the rotating shaft 4 rotates. For this purpose, as shown in fig. 5 and 6, a hinge cavity 21 is disposed on a side surface of the connector 15, and a limit block 22 is disposed on a side of the hinge cavity facing away from the rotation direction of the rotating shaft 4. The end of the connecting sleeve 16 remote from the short square rod 13 extends into the hinge cavity 21 and forms a hinge with the connector 15. With this structure, when it is necessary to mount and dismount the collecting box 7, the coupling sleeve 16 can be rotated so as to deviate from the radial direction of the rinsing cartridge 1, leaving sufficient operating space. When the collecting box 7 is installed in place and the rotating shaft 4 rotates, the collecting box 7 is communicated with the connecting sleeve 16 and can be blocked by the limiting block 22, and excessive rotation is prevented.
