Abstract
The utility model discloses improved doffer card clothing which comprises a card clothing base. The card clothing base is provided with circular needle tooth holes. A semicircular protrusion is disposed in each circular needle tooth hole, a needle tooth is mounted on the circular needle tooth hole, the lower portion of the needle tooth is provided with a circular bottom, the height of the circular bottom is identical with the depth of the circular needle tooth hole, the radius of the circular needle tooth hole is identical with the radius of the circular bottom, and a groove matched with the semi-circular protrusion is formed in the circular bottom. Each semi-circular protrusion is elastically connected with the card clothing base, the semi-circular protrusion is extruded to moved into the card clothing base and returns in an elastic manner when no extrusion exists. A certain angle is formed between each needle tooth and the corresponding circuit bottom. The improved doffer card clothing is simple in structure, convenient and practical. When one needle tooth is abraded, the abraded needle tooth on a doffer can be preplaced by a new one, convenient replacement is achieved, and time and cost are saved.
Description
Technical field
The utility model relates to wool spinning apparatus field, more specifically says a kind of improved doff clothing.
Background technology
In use for some time, the pin tooth on doffer can not be used due to wearing and tearing traditional doffer, continues to use the quality that can reduce wool spinning product.At this moment just must change doffer, the trouble that this not only compares, has also increased production cost.
Utility model content
The purpose of this utility model is in order to make up the deficiencies in the prior art, and a kind of improved doff clothing is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of improved doff clothing, comprise card clothing matrix, it is characterized in that: on described card clothing matrix, be provided with round pin perforation, in round pin perforation, be provided with semi-cylindrical hill, pin tooth is installed on round pin perforation, and the bottom of pin tooth is provided with circular base, and the height of circular base is identical with the degree of depth of round pin perforation, the radius of round pin perforation is identical with the radius of circular base, is provided with the groove matching with semi-cylindrical hill in circular base.
Described a kind of improved doff clothing, is characterized in that: between described semi-cylindrical hill and card clothing matrix, elasticity connects, and semi-cylindrical hill is squeezed and moves in card clothing matrix, during without extruding, rebounds.
Described a kind of improved doff clothing, is characterized in that: between described pin tooth and circular base, have certain angle.
The utility model has the advantage of:
The utility model is simple in structure, convenient and practical, after pin odontotripsis, only the pin tooth on doffer need be pulled out, and changes newly, is both convenient for changing, and saves time and cost again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model card clothing basal body structure schematic diagram.
Fig. 3 is the utility model pin toothing schematic diagram.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of improved doff clothing, comprise card clothing matrix 1, on described card clothing matrix 1, be provided with round pin perforation 2, in round pin perforation 2, be provided with semi-cylindrical hill, pin tooth 3 is installed on round pin perforation 2, the bottom of pin tooth 3 is provided with circular base 4, the height of circular base 4 is identical with the degree of depth of round pin perforation 2, and the radius of round pin perforation 2 is identical with the radius of circular base 4, is provided with the groove 5 matching with semi-cylindrical hill in circular base 4.Between described semi-cylindrical hill and card clothing matrix 1, elasticity connects, and semi-cylindrical hill is squeezed to the interior movement of card clothing matrix 1, during without extruding, rebounds; Between described pin tooth 3 and circular base 4, there is certain angle.
