Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine technology, specifically a yarn outlet for roving on a flat knitting machine. Background Technology

[0002] A flat knitting machine is a type of mechanical equipment used to produce knitted fabrics. It mainly consists of a needle bed, a carriage, and a yarn guide. The knitting needles on the needle bed move up and down in a regular manner under the drive of the carriage, knitting the yarn into fabric. Flat knitting machines are widely used in the production of knitted garments and accessories such as sweaters, scarves, gloves, and hats. A yarn outlet is installed at the output end of the yarn guide to assist in guiding the yarn out.

[0003] Currently, most yarn feeders rely on their own material and smooth surface to directly rub against the yarn, resulting in a high loss rate and frequent replacements. Furthermore, most flat knitting machines are used to knit wool products, and the yarn they convey is mostly coarse, with a rougher surface, leading to even greater losses from the yarn feeder. Utility Model Content

[0004] The purpose of this invention is to provide a yarn outlet for roving on a flat knitting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A yarn feeder for a flat knitting machine roving, comprising:

[0007] Mounting structure, including mounting handle;

[0008] The yarn outlet structure is fixedly installed at the lower end of the mounting handle. The yarn outlet structure includes a wedge-shaped guide cover. A first auxiliary roller is rotatably installed on the front and rear edges of the lower opening of the wedge-shaped guide cover, and a second auxiliary roller is rotatably installed on the sides of the lower opening of the wedge-shaped guide cover.

[0009] Furthermore, an adjustment groove is provided in the middle of the mounting handle, and a mounting bolt is installed in the adjustment groove.

[0010] Furthermore, the mounting handle has two fixed mounting strips on the rear surface of both sides, and two fixed mounting strips on the front surface of both sides.

[0011] Furthermore, a back plate is fixedly installed at the lower end of the mounting handle, and a wedge-shaped guide cover is fixedly installed at the lower end of the front surface of the back plate, with an observation window interspersed on the front side of the wedge-shaped guide cover.

[0012] Furthermore, a weight-reducing groove is interspersed in the middle of the back plate in the front-to-back direction.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The entire structure is fixedly installed at the output end of the yarn guide structure of the flat knitting machine by the mounting handle. The roving passes through the wedge-shaped guide cover and is guided by the opening at the lower end of the wedge-shaped guide cover to exit. When the yarn exiting nozzle structure moves to adjust the yarn exiting position, the first auxiliary roller and the second auxiliary roller replace the inner wall of the wedge-shaped guide cover to directly contact the roving. The rolling feeding method replaces the direct friction between the inner wall of the wedge-shaped guide cover and the delivered roving, reducing friction loss, improving the service life of the overall structure, and reducing the replacement frequency of the yarn exiting nozzle structure.

[0015] The entire structure is installed by screwing the mounting bolt through the adjusting groove into the output end of the yarn guide structure of the flat knitting machine. The actual height of the wedge-shaped guide cover is adjusted by sliding the adjusting groove up and down on the side surface of the mounting bolt. During installation, the overhead strip abuts against the side surface of the output end of the yarn guide structure to form an overhead layer. The force strip is directly abutted by the large end of the mounting bolt, so that the mounting handle tends to be concave into the overhead layer during installation, which improves the installation tightness.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the present invention, a yarn outlet for roving on a flat knitting machine includes an installation structure 1, which includes an installation handle 101; a yarn outlet structure 2 is fixedly installed at the lower end of the installation handle 101, and the yarn outlet structure 2 includes a wedge-shaped guide cover 203. A first auxiliary roller 205 is rotatably installed on the front and rear edges of the lower opening of the wedge-shaped guide cover 203, and a second auxiliary roller 206 is rotatably installed on the sides of the lower opening of the wedge-shaped guide cover 203.

[0023] Specifically, the entire structure is fixed to the output end of the yarn guiding structure of the flat knitting machine by the mounting handle 101, and the roving passes through the wedge-shaped guide cover 203. Under the guidance of the lower opening of the wedge-shaped guide cover 203, the yarn is discharged. When the yarn outlet structure 2 moves to adjust the yarn outlet position, the first auxiliary roller 205 and the second auxiliary roller 206 replace the inner wall of the wedge-shaped guide cover 203 to directly contact the roving. The rolling feeding method replaces the direct friction between the inner wall of the wedge-shaped guide cover 203 and the discharged roving, reducing friction loss, improving the service life of the overall structure, and reducing the replacement frequency of the yarn outlet structure 2. Example

[0024] like Figure 1-4 As shown, in this embodiment, a back plate 201 is fixedly installed at the lower end of the mounting handle 101, and a wedge-shaped guide cover 203 is fixedly installed at the lower end of the front surface of the back plate 201. An observation window 204 is interspersed on the front side of the wedge-shaped guide cover 203; a weight reduction groove 202 is interspersed in the middle of the back plate 201 in the front-back direction.

[0025] In this embodiment, the upper and lower ends of the back plate 201 are not on the same plane. The wedge-shaped guide cover 203 is extended forward by a certain distance through the back plate 201, so as to avoid excessive friction and wear caused by other parts of the overall structure directly contacting the yarn when the wedge-shaped guide cover 203 guides the yarn. At the same time, the situation can be observed through the observation window 204 during use. Example

[0026] Based on Embodiment 1, in order to supplement the specific method of installing the overall structure at the output end of the yarn guide structure of the knitting flat knitting machine by means of the installation structure 1, which was not mentioned in Embodiment 1.

[0028] In practice, the installation bolt 103 is screwed into the output end of the yarn guide structure of the flat knitting machine through the adjusting groove 102 to install the overall structure. The actual height of the yarn outlet of the wedge-shaped guide cover 203 can be adjusted by sliding the adjusting groove 102 up and down on the side surface of the installation bolt 103. During installation, the overhead strip 104 abuts against the side surface of the output end of the yarn guide structure to form an overhead layer. The force strip 105 is directly abutted against by the large end of the installation bolt 103, so that the installation handle 101 tends to be concave into the overhead layer during installation, thereby improving the installation tightness.
