Description

Cotton feeding protection device applied to air spinning

Technical Field

The utility model relates to a spinning machine part technical field, concretely relates to application is spun at air current and is given cotton protection device.

Background

The cotton feeding operation is completed through the matching of the cotton feeding roller and the cotton feeding plate in the air spinning, when a cotton sliver passes through the cotton feeding plate, the spring plate can generate certain deformation under the influence of the thickness of the cotton sliver, and the working surface of the roller head is rough, so that the stable operation of the cotton sliver on the cotton feeding plate can be ensured, and the cotton sliver can enter the carding cavity to be carded. However, when the spinning device continues to work without sliver, the cotton feeding plate approaches the roller head under the action of the elastic force of the spring plate and abuts against the working surface of the roller head, so that the cotton feeding plate or the roller head is abraded.

Furthermore, since the sliver is not exactly uniform in size when it is moved, the feed plate will undulate, and the spring force provided by the spring plate will be non-uniform, which will result in a displacement of the feed plate in the axial direction of the pin, which axial movement is detrimental to the feed plate and will affect the stability of the feed. And present give cotton board most be integral type casting shaping, and give cotton board's working face because the long time friction of working easily wears and teares, need to give the panel to change or need pull down whole cotton board when maintaining, complex operation and extravagant cost.

SUMMERY OF THE UTILITY MODEL

the cotton feeding plate is characterized in that at least one end of the roller head is provided with a limiting sleeve, the radial size of the limiting sleeve is larger than that of the roller head, and when the cotton feeding plate does not work, the ceramic surface abuts against the limiting sleeve.

The cotton feeder is further provided with a limiting mechanism at the hinged position of the spring plate and the cotton feeding plate, and the limiting mechanism is used for limiting the axial freedom degree of the cotton feeding plate along the pin shaft.

The cotton feeding device is characterized in that the limiting mechanism comprises baffle plates which are respectively positioned at the upper end and the lower end of the cotton feeding plate and extend towards the side surface, and the upper side and the lower side of the spring plate are respectively abutted against the baffle plates.

The cotton feeding plate and the ceramic surface are in split design.

The arrangement is further such that the ceramic surface is attached to or snapped onto the cotton feed plate.

Compared with the prior art, the utility model, its beneficial effect lies in:

1. the utility model arranges the limit sleeve on the roller head, when the cotton feeding plate works, the cotton feeding plate is not contacted with the limit sleeve because cotton strips are arranged between the roller head and the working surface of the cotton feeding plate, and the normal operation of the cotton feeding can be ensured; when no cotton sliver exists between the roller head and the cotton feeding plate, the cotton feeding plate is propped against the limiting sleeve under the elastic action of the spring plate, so that the cotton feeding plate and the roller head always keep a certain gap, and the cotton feeding plate and the roller head are prevented from being directly contacted to cause unnecessary damage.

2. The utility model discloses restrict the axial degree of freedom for cotton feeding plate, effectively avoided cotton feeding plate during operation because of reciprocating that the change of spring board atress leads to, guaranteed the stability of mechanism work.

3. The utility model discloses the working face that will give cotton board sets up to the ceramic face to reduce wear, and ceramic face and the split type connection of giving cotton board provide convenience for changing and maintaining.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): a cotton feeding protection device applied to air spinning comprises a roller head 1, a cotton feeding plate 2 and a spring plate 3, wherein the cotton feeding plate 2 is rotatably arranged on a machine table 7 through a pin shaft 4, the spring plate 3 is bent, one end of the spring plate is clamped on one side of the end part of the cotton feeding plate 2, which is far away from the pin shaft 4, and the other end of the spring plate is clamped with a spinning device 8; the back of the cotton feeding plate 2 at one side provided with the spring plate 3 is provided with a ceramic surface 5, the ceramic surface 5 is matched with the roller head 1, and when the cotton feeding plate 2 works, the ceramic surface 5 presses the cotton sliver on the working surface of the roller head 1 under the elastic force action of the spring plate 3.
