Description

Yarn winding moving rod cam

Technical Field

The utility model relates to a textile machinery accessory technical field, concretely relates to coiling yarn move lead screw cam.

Background

When the two-for-one twister winds twisted yarns for forming, the yarns can be wound on a yarn bobbin according to certain density and lines mainly by the left-right reciprocating movement of the feed moving rod, and the left-right reciprocating movement of the feed moving rod is mainly realized by the transmission of the convex ring.

Chinese patent No. CN203021717U discloses a cam of a two-for-one twister feed screw rod, which comprises a cam and a rotating shaft, wherein the cam is provided with a smooth arc part. The cam of the screw moving rod is too simple in design and is easy to misplace.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the shortcoming that exists among the prior art, and the lead screw cam that moves of a coiling yarn that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a yarn is convoluteed moves lead screw cam, includes bulge loop and pivot, the pivot is located the axle center position of bulge loop, and is certain angle slope setting between bulge loop and the pivot, pivot circumference is provided with many strengthening ribs of being connected with the bulge loop, the shape of bulge loop is oval, and a tip of oval bulge loop major axis forms first protruding position to the left side evagination, and another tip forms the protruding position of second through to the right side evagination, the guide way has been seted up to the outside terminal surface of bulge loop.

Preferably, six reinforcing ribs are arranged and are uniformly distributed on the periphery of the rotating shaft.

Furthermore, the convex ring, the rotating shaft and the reinforcing ribs are integrally cast and formed.

Furthermore, a pot head of pivot is equipped with the bearing frame, be equipped with the screw hole on pivot and the bearing frame.

Furthermore, the axle center of the rotating shaft is provided with an axle hole penetrating through the rotating shaft.

The utility model has the advantages that: the guide groove is additionally arranged on the convex ring, so that the cam follower has a guiding effect, the cam follower cannot fly away from the convex ring due to high-speed rotation, and meanwhile, the screw holes are additionally arranged on the rotating shaft and the bearing seat, so that the screw rod moving cam can be fixedly arranged on the two-for-one twister.

In the figure, 1-convex ring, 11-first convex part, 12-second convex part, 13-guide groove, 2-rotating shaft, 21-rotating shaft hole, 22-bearing seat, 23-screw hole and 3-reinforcing rib.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-3, this embodiment is a yarn winding moving rod cam, including pivot 2 and bulge loop 1, pivot 2 is located the axle center position of bulge loop 1, and be certain angle slope setting between bulge loop 1 and the pivot 2, through the setting of this kind of slope, can increase the scope that guide way 13 led, bulge loop 1 and pivot 2 are casting forming as an organic whole, 2 circumference of pivot are provided with many strengthening ribs 3 of being connected with bulge loop 1, strengthening rib 3 is provided with six, and the equipartition is in 2 peripheries of pivot, the effect of strengthening rib 3 is the steadiness of guaranteeing between bulge loop 1 and the pivot 2. Guide groove 13 has been seted up to the outside terminal surface of bulge loop 1, and guide groove 13's effect leads to the cam follower, makes the cam follower can not fly away from bulge loop 1 because of high-speed rotation, and the cam follower can follow along with guide groove 13 rotates and remove moreover.

The shape of the convex ring 1 is an ellipse, one end part of the major axis of the ellipse convex ring 1 protrudes towards the left side to form a first convex position 11, the other end part protrudes towards the right side to form a second convex position 12, the surfaces of the first convex part 11 and the second convex part 12 are smooth, and the range guided by the guide groove 13 can be enlarged by arranging the smooth first convex part 11 and the smooth second convex part 12.

The shaft hole 21 that runs through pivot 2 is seted up to the axle center of pivot 2, and the bulge loop passes through pivot hole 21 to be installed on the two-for-one twister, and the bottom cover of pivot 2 is equipped with bearing frame 22, is equipped with screw hole 23 on pivot 2 and the bearing frame 22, fixes pivot 2 on the two-for-one twister through screw hole 23.

In the in-service use process, the utility model discloses install on the two-for-one twister, move the lead screw cam and install in the pivot of two-for-one twister through 2 epaxial pivot holes 21 of pivot, it is fixed through screw hole 23, move the lead screw cam and rotate along with the rotation of two-for-one twister pivot in work.
