CN2241701Y - Needle selection mechanism for circular knitting machine - Google Patents

Abstract

The utility model relates to a needle selection mechanism for a circular knitting machine, which is provided with a separable needle selection device. The needle selection device is provided with a plurality of thimble sheets which are opposite to needle selection pushing sheets of the needle selection mechanism. The thimble sheets can rotate to push or not to push the position of the needle selection pushing sheets. When the needle selection device is loaded again in the needle selection mechanism, the thimble sheets in different positions push the needle selection pushing sheets in the top mechanism, which further controls the needles to carry out three different movements of whole needle, semi-needle and flat needle to weave a kind of arabesquitic fabrics.

Description

The selecting mechanism of tubular knitting machine

The utility model is a kind of selecting mechanism of tubular knitting machine, particularly a kind ofly is installed on knitting needle stitch place in the knitting machine, and optionally the interlock knitting needle is done motions such as full pin, half pin or flat pin, in order to be made into the selecting mechanism of pattern fabric.

Utilize the knitting needle that raises of pin choosing and plate pushing selecting type in the selecting mechanism, or the heavy sheet (Sinker) of release, use the technology that cloth cover has the fabric of decorative pattern that is made into, it has been well-known technology, selecting mechanism is wherein compiled type because of the circle that is used in difference again different types, have following six kinds haply, a. fancy flange type (Fancy cams), b. floral whorl type (Pattern Wheels), c. inserted sheet type (Pattern Blade), d. flower-drum type (Pattern Drums), for example approved Britain the 572nd, those disclosed herein are this kind of, e. lace type (Pattern Tapes) in No. 908 and the 709th, No. 209 patent, f. jacquard weave roller type (Jacquad roller), and the inserted sheet type that the utility model disclosed takes off before promptly being; Inserted sheet type person is among all selecting mechanisms, be that structure is the simplest a kind of, its shared space is less just because of this, around same size diameter, just many feeds can be installed, advantages such as in addition, it also has the car of changing facility, and is with low cost, the pin choosing and plate pushing of this kind blade inserting selecting mechanism, both can singly only install, also can be two only arranged side by side, the former can only be in order to generate two positions needle selection decorative pattern, the latter can (be full pin in order to generate three positions then, half pin, flat pin) needle selection decorative pattern is a kind of traditional type structure of the latter as shown in Figure 1.

By seeing among Fig. 1, the pin choosing and plate pushing of this inserted sheet type selecting mechanism is to be installed on the body in a plurality of overlapping modes indirectly, this pin choosing and plate pushing has the parallel arcuate socket in two roads, and the axostylus axostyle activity of two correspondences of mat work is hubbed at body, must utilize hand tool just can finish mobile work when changing the position of this pin choosing and plate pushing, what well imagine is, many and the overlapping pin choosing and plate pushing of quantity in each selecting mechanism, to great burden for adjustment work, and in a round volume machine 36 groups of selecting mechanisms nearly, even under the more condition, certainly will more difficult finishing.

Therefore, main purpose of the present utility model will provide a kind of change pin choosing and plate pushing very to be easy to selecting mechanism exactly, the pin choosing and plate pushing of this mechanism is to rearrange with overlapping relation equally, only, this mechanism has a separable needle selection device, on the needle selection device and dispose and each group pin choosing and plate pushing equivalent corresponding needle jack-up piece, these needle jack-up pieces all are that the mode with activity is hubbed on the needle selection device, therefore can with finger needle jack-up piece be rotated to the desired position easily, after the needle selection device is reinstalled mechanism, this needle jack-up piece just can the ejection correspondence pin choosing and plate pushing, and then finish full pin, the needle selection position of flat pin or half pin; Therefore, whenever will be again changing in the car operation as needle selection, the staff only need unload the needle selection device, and after the needle jack-up piece on it rotated to the tram, puts in back selecting mechanism.Can finish the needle selection operation, its mode of operation is obviously easier, even will check that correction is also extremely convenient.

The selecting mechanism of a kind of tubular knitting machine that provides according to the utility model, this selecting mechanism has: a body comprises two pin choosing and plate pushings and a plurality of needle selections unit that overlaps each other and is installed on this body arrives full pin, half pin or flat pin position in order to this pin choosing and plate pushing of ejection needle selection device on the upright position; The part of its improvement includes: the front of aforementioned needle selection device has and the corresponding ditch portion of aforementioned needle selection unit equivalent; This ditch portion ties up to horizontal direction and extends, level two side positions of aforementioned arbitrary ditch portion are pivoted with the needle jack-up piece in order to the aforementioned relative pin choosing and plate pushing of ejection optionally respectively, this needle jack-up piece all has a nose, and this nose and pivoting point that can this needle jack-up piece are that the center rotates to the position releasing or do not release this pin choosing and plate pushing, by this, after this needle selection device was reinstalled aforementioned body again, the nose of this needle jack-up piece just can promote the position that this pin choosing and plate pushing arrives full pin, half pin or flat pin.
