Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for attaching and detaching a fixed flat in a roller card for woolen wool, worsted wool, etc.

Generally, long fibers such as wool are efficiently carded using a roller card, but the problem of removing neps and short fibers adhering to the flats always arises.
The recent demand for higher quality yarns in the spinning industry also applies to the spinning and carding fields, and there is a need for technological responses.

A flat card is used in the carding process for short fibers such as cotton, and the removal of extremely small short fibers and neps and dregs is a more serious problem than for long fibers.

Therefore, it is natural to consider applying the flat card technique to carding wool. This spinning wool・
When a fixed flat is applied to the worsted card, it is clear that short fibers and neps are removed and the quality is improved, but the top needle cloth is heavily embedded with fiber waste, making it difficult to maintain the cleaning cycle to maintain functionality. Since the length is short, it is necessary to frequently remove the fiber waste embedded in the needle base of the top clothing, that is, to clean it.

However, it is necessary to remove several dozen fixed flats each time the cleaning is performed, which poses a problem in management or production, including the need to stop the machine, resulting in a reduction in production volume and increased costs.

On the other hand, using a rotating flat would solve this problem, but the machine width of a card using a rotating flat is 40 inches, whereas the machine width of a roller card is 60 inches to 100 inches, and the top needle is wider. This is applied because it is difficult to maintain the gap gauge between the fabric and the needle tip of the cylinder at a certain level of accuracy, which can lead to needle contact, and setting a wide gap gauge for fear of contact will reduce the combing action. It is difficult to do so.

The present invention solves the above-mentioned problems, and provides a fixing flat for woolen and worsted roller cards that is configured to simplify the attachment and detachment of the fixed flat for woolen and worsted roller cards, and to facilitate cleaning. It provides a mechanism.

An embodiment of the present invention will be described below based on the drawings.

FIGS. 1 and 2 are a side view and a sectional view showing a fixing flat attaching/detaching mechanism of the present invention applied to a roller card.

Side bend 1 of roller card cylinder machine base
A convex bracket 3 having a flat bend mounting surface 5 is positioned on the bracket mounting surface 2 with a dowel pin 4 and fixed with bolts and nuts. The flat bend mounting surface 5 having the notch 31 in the upper part of the bracket 3 is provided with a notch 31, and the flat bend mounting surface 5 has a curved surface coaxial with the side bend peripheral surface 6, so that the side bend peripheral surface Form slightly higher than the Further, a pin receiver 7 is integrally fixed to the bracket 3 on the back surface of the flat bend mounting surface 5, and a clamp bolt 9 is rotatably supported by a pin 8. Arc-shaped flat bends 12 are formed so as to be placed on the flat bend mounting surfaces 5 formed at left and right opposite positions in the axial direction as described above. This flat bend 12 is provided with a notch 11 at a position corresponding to the fixed flat bar mounting surface 10 and the clamp bolt 9 mounted on the back side of the flat bend mounting surface. In addition, a plurality of fixed flat bars 13 are installed between the flat bar mounting surfaces 10 of the left and right flat bends.
Place the bar end part of and tighten the adjustment bolt 14.
Adjust the clearance gauge 16 with the cylinder 15 with
A fixing flat is placed on the cylinder 15, with each fixing flat bar 13 being fixed by fixing bolts 17 to form an integrated structure. Next, a notch 11 provided at the end of the left and right flat bends and a notch 31 provided on the flat bar mounting surface 5 of the bracket.
The clamp bolt 9 rotatably supported on the back side of the flat bar mounting surface is rotated and fitted into the notch, and the clamp nut 18 screwed onto the upper end of the clamp bolt and the clamp nut are rotated. The attachment/detachment mechanism for the roller card fixing flat is configured so that the fixing flat can be easily tightened and fixed or loosened and removed using a movably attached clamp handle 19.

Note that a plurality of solid flats forming the above-mentioned integrated structure may be used and arranged as appropriate, and the flat bend 12 is fixed using the clamp bolt 9 due to the space.
and the convex bracket 3 by the clamp nut 18.
However, by using a toggle clamp with a torque mechanism, the attachment/detachment operation can be made even faster. Alternatively, after fixing the hanging rod 21 to the side surface 20 of the flat bend and removing the clamp bolt, the integrated structure of the flat bend and the fixed flat bar can be removed using a lifting device or by grasping it by hand.

After opening the top clothing surface in this way and cleaning the top clothing 22 manually or with a vacuum cleaner,
Re-install the fixing flat of the integrated structure into bracket 3.
The clamp bolt 9 is rotated to fit into the notch, and the clamp nut is tightened to complete the installation. At this time, the gap gauge reproduces the same condition as when it was removed, so readjustment is not required.

As mentioned above, the present invention allows several to dozens of fixed flat bars to be fixed without changing the feeler gauge.
It can be easily removed and installed, reducing machine down time, cleaning time, installation and removal time, and increasing production efficiency. Further, it does not require expensive equipment such as a rotating flat, and can be easily and inexpensively installed. Furthermore, this invention has excellent effects such as making it possible to form high-quality yarn.
