Description

Technical Field

[0001] The utility model relates to the technical field of seamless knitting equipment, in particular to a high-density seamless knitting equipment. Background Art

[0002] Knitting machines are a process in which yarns of various raw materials and varieties are formed into coils using knitting needles and then connected into knitted fabrics through stringing. Knitted fabrics have a soft texture, good wrinkle resistance and breathability, and great extensibility and elasticity, making them comfortable to wear. In addition to being used for clothing and decoration, knitted products can also be used in industry, agriculture, medical care, health care, and national defense. Knitting is divided into two categories: hand knitting and machine knitting.

[0003] Knitting equipment connects the yarn on the bobbin to the knitting equipment. When the knitting equipment is running, the yarn is pulled to drive the bobbin to rotate freely. However, since conventional bobbins rotate freely and there is a certain distance between the bobbin and the knitting equipment, some knitting equipment will cause the yarn to become excessively loose and shake during operation, which can easily affect the normal operation of other parts of the equipment. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-density seamless knitting device, which can increase the friction when pulling the yarn through the extrusion tube and can position the yarn tube up and down, thus solving the problems mentioned in the background technology.

The vertical plates are all installed on the fixed plates, the electric push rods are all installed on the vertical plates, the piston rods of the electric push rods are all installed on the pressure rods, and the outer ring surfaces of the pressure rods are all arranged in contact with the outer ring surfaces of the extrusion rollers.

[0009] As a preferred technical solution, fixing seats are installed at both ends of the fixing plate, the fixing seats are arranged in an "L"-shaped structure, and straight slots are provided on the fixing seats.

[0010] As a preferred technical solution, the cross-sections of the slider and the slide groove are both arranged in a trapezoidal structure, a compression spring is installed at one end of the slider facing the yarn tube, and the other end of the compression spring is installed on the inner wall surface of the slide groove.

DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a high-density seamless knitting device of the utility model comprises a fixed plate 1 installed on the seamless knitting device, one side of the fixed plate 1 is bent to form an inclined plate 2, a plurality of rotating shafts 4 are installed on the fixed plate 1, a yarn tube 5 is sleeved on the outer side of the rotating shaft 4, a slide groove 12 is provided on the surface of the inclined plate 2 facing the rotating shaft 4, a slider 13 is slidably installed in the slide groove 12, an extrusion roller 6 in contact with the yarn tube 5 is movably installed on the slider 13, and a driving mechanism for pushing the extrusion roller 6 to move toward the yarn tube 5 is provided on the outer side of the plurality of extrusion rollers 6.

[0021] In this embodiment, the fixed plate 1 is provided with an installation hole 15 opposite to the rotating shaft 4, and the first sealed bearing 3 is installed in the installation hole 15. The lower end of the rotating shaft 4 is installed in the inner ring of the first sealed bearing 3. A positioning ring is installed on the rotating shaft 4, and the top surface of the positioning ring is in contact with the bottom surface of the yarn tube 5.

[0022] In this embodiment, the squeezing rollers 6 are all arranged at an angle, and the inclination degree of the squeezing rollers 6 matches the inclination of the outer ring of the yarn tube 5. A second sealed bearing is embedded on the top surface of the slider 13, and the shaft rollers at the lower ends of the squeezing rollers 6 are installed in the inner ring of the second sealed bearing.

[0023] In this embodiment, the driving mechanism includes a pressure rod 9, a plurality of vertical plates 7 and a plurality of electric push rods 8. The vertical plates 7 are all mounted on the fixed plate 1, the electric push rods 8 are all mounted on the vertical plates 7, and the piston rods of the electric push rods 8 are all mounted on the pressure rod 9. The outer ring surface of the pressure rod 9 is arranged in contact with the outer ring surface of the extrusion roller 6, so that the rotation of the extrusion roller requires friction with the pressure rod. The friction can reduce the rotation speed of the extrusion roller, thereby controlling the rotation speed of the yarn tube.

[0024] In this embodiment, fixing seats 11 are installed at both ends of the fixing plate 1. The fixing seats 11 are all arranged in an "L"-shaped structure. Straight slots are provided on the fixing seats 11, and bolts can pass through the straight slots to fix the device on the seamless knitting equipment.

[0025] In this embodiment, the cross-sections of the slider 13 and the slide groove 12 are both arranged in a trapezoidal structure. A compression spring 14 is installed at one end of the slider 13 facing the yarn tube 5, and the other end of the compression spring 14 is installed on the inner wall surface of the slide groove 12. After the pressure rod is away from the extrusion roller, the slider and the extrusion roller can be pushed outward by the rebound of the compression spring, so that the extrusion roller is set away from the yarn tube. After the outside of the yarn tube loses its obstruction, it can be directly removed along the rotating shaft, which is convenient for disassembly and assembly.

[0026] When in use, the yarn bobbin can be directly put on the transfer account, and the bottom surface of the yarn bobbin can contact with the positioning ring. In the process of yarn pulling, the electric push rod can be activated to make the piston rod of the electric push rod slowly extend. The extension of the piston rod drives the pressure rod, and the pressure rod can push the squeezing roller toward the yarn bobbin until the outer ring surface of the squeezing roller contacts with the outer ring surface of the yarn bobbin. Since the squeezing roller is set at an angle, the yarn bobbin can be positioned up and down, avoiding the situation where the yarn bobbin moves up and down, and increasing stability.

[0027] In the process of yarn pulling out, the yarn can always be in contact with the squeezing roller, and the rotation speed of the yarn tube is reduced by friction with the squeezing roller, so that the pulled yarn is straightened, and as the yarn is pulled out, the diameter of the yarn tube will shrink. As the yarn tube shrinks, the electric push rod can gradually extend so that the squeezing roller can always be in contact with the outer ring of the yarn tube.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
