Abstract

The present invention discloses a knitting machine for manufacturing long-pile fabric, which comprises: cylinder needles without needle latches arranged on a needle cylinder, latch needles arranged on a needle disk, and a shearing unit, whereby loops formed by wool yarn are directly knitted into a ground structure woven by a base yarn in a fabric, so that a long pile is formed on the surface of the fabric; a preferred embodiment thereof is to increase the distance between the edge of the needle disk and the cylinder needles by changing the size of the needle disk, so that the wool yarn hung on the needle hook of the cylinder needle can be pulled by the latch needles to form a long loop, and finally the loop is cut by the shearing unit to form a long-pile fabric with a long pile.

Description

Knitting machines for making plush fabrics

technical field

The invention relates to a circular knitting machine, in particular to a plush knitting machine capable of producing longer piles.

Background technique

Knitting machines used to make plush fabrics are also known as faux fur knitting machines. The technology of utilizing a circular knitting machine to manufacture plush fabrics is also well known. For example, in the US Patent No. 6,735,987 that has been approved and announced, it mainly utilizes a latch needle that is arranged on the needle cylinder and a plurality of needles that are horizontally arranged on the dial. The interactive operation of the Sinkers makes the yarn hang on the front edge of the Sinkers to form a longer loop.

In the US Patent No. 6,128,930, US Patent No. 6,094,944, and the approved US Patent No. 5,463,882 that have been approved and announced, basically all are to utilize the tube needles without latches arranged on the needle cylinder, arranged on the dial (needle dial) latch needle and shearing unit interact to produce a plush fabric, in which the loops are formed at the hook of the cylinder needle without a latch, and the wool hanging at the needle junction of the cylinder needle The loops are then cut into plush piles by using two pressing Schenck sheets that slide through both sides of the cylinder needle and a Schenck sheet with a knife edge at the front end.

In the aforementioned two known technologies of U.S. Patent No. 930' and No. 882', the length of the pile is determined by the distance from the needle hook of the barrel needle to the edge of the dial. Generally speaking, the finished plush made by this type of technology The fluff length of the fabric is about 3mm. When this kind of fluff fabric is applied to artificial fur or as the fur of toy dolls, it is difficult to achieve a realistic effect with only 3mm fluff. If you want to increase the length of fluff, you must increase If the distance from the needle hook of the needle cylinder to the edge of the dial is to be achieved by increasing the diameter of the needle cylinder, the diameter of the sinker ring (sinkerring) surrounding the periphery of the needle cylinder for carrying the blade also needs to be increased. But increasing the diameter of the Schenck sheet ring will change the relative position and size of the blade and the cylinder needle on it, and even cause the gap between the blade and the cylinder needle to be too large to cut the loop into plush.

Contents of the invention

The main purpose of the present invention is to provide a knitting machine for making plush fabrics, especially a plush knitting machine capable of obtaining piles with a length of up to 12 mm.

A knitting machine for producing plush fabrics according to the present invention, comprising: a cylinder needle without a latch arranged in the needle cylinder, a latch needle horizontally arranged on the dial, and a shearing unit, wherein by changing the position of the dial In the way of size, the distance between the edge of the dial and the cylinder needle is increased, and the wool yarn is formed into a loop at the hook of the cylinder needle without a latch, and then the wool yarn is looped by the latch needle arranged on the dial After pulling the wool yarn, longer piles can be formed, and finally the piles are cut by the shearing unit to form a plush fabric with longer piles.

The knitting machine for making plush fabric according to the present invention can obtain plush up to 12 mm in length.

Detailed ways

The detailed technical contents and preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

First please refer to Fig. 1, which shows the knitting unit of a circular knitting machine for making plush fabrics, that is, the part that converts yarns into fabrics, according to a preferred embodiment of the present invention, for making plush fabrics Circular knitting machines include:

Arranged in cylinder needle 11 without latch of needle cylinder (Cylinder) 10, is arranged in the latch needle (latch needle) 21 of dial (needle dial) 20, and cut suede unit (cuttingunit) 30; Cut suede unit 30 comprises two A group of Schenck sheets 31, 32 (see Fig. 2) and protrusions (cam) 33, the Schenk sheets 31, 32 are slid over the both sides of the cylinder needle 11 respectively simultaneously by the protrusions 33, One of the Schenck sheets 31 has a knife edge 310, and the knife edge 310 can cut off the pile 41 formed by the wool yarn 40 when sliding over the cylinder needle 11, and generate plush (see FIG. 3 ).

According to a preferred embodiment of the present invention, by changing the size of the dial 20, the distance D between the edge 22 of the dial and the hook 112 of the cylinder needle is increased to between 10 and 15 mm, so that the The wool yarn 40 at 112 can be pulled by the latch needle 21 to form a longer pile 41, and finally the pile 41 is cut off by the shearing unit 30 to form a plush fabric with a pile length of about 12 mm.

The process of making plush is shown in Figures 4 to 7. First, the plush thread 40 is fed between the front edge 110 of the cylinder needle and the hook 210 of the latch needle, and the ground thread 50 Then it is fed between the rear end 111 of the cylinder needle and the edge 22 of the dial (see Fig. 4), and when the latch needle 21 moves toward the left in Fig. Rising to the yarn eating height of the wool yarn 40, the wool yarn 40 will be pulled by the hook 210 of the latch needle and hung on the hook 112 of the tube needle to form a pile 41, the latch needle 21 continues to narrow the needle and hook the bottom yarn 50 and Belt to the hypotenuse 23, and then under the guidance of the hypotenuse 23, it gradually approaches the bottom of the needle hook 210, and then the ground yarn 50 will move to the bottom of the wool yarn 40 (see Figure 6), then, the cylinder needle 11 descends and uses the needle The hook 112 tightens the loop 41, and through the interaction of the cylinder needle 11 and the latch needle 21, the loop 41 formed by the wool yarn 40 is directly woven into the ground tissue woven by the ground yarn 50 in the knitted fabric, and finally The loops 41 are cut by the shearing unit 30 to form a plush fabric with longer piles.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
