Description

Technical Field

[0001] This utility model relates to the field of knitting machine heart technology, and more specifically, to a knitting machine heart with a protective structure. Background Technology

[0002] A knitting machine is a machine used for knitting fabrics and is widely used in clothing, home furnishings, and other fields. With the advancement of technology, modern knitting machines pursue higher speeds and efficiency. For example, circular knitting machines and multi-triangle knitting machines are widely used in knitting enterprises to produce various new types of fabrics. A circular knitting machine consists of a frame, yarn feeding mechanism, knitting mechanism, transmission mechanism, lubrication and dust removal mechanism, electrical control mechanism, drafting and take-up mechanism, and other auxiliary devices. Among them, the knitting mechanism is the heart of the circular knitting machine, mainly composed of components such as the cylinder, needles, triangles, and triangle seats.

[0003] A search revealed that utility model patent CN208183210U discloses a protective cover for the knitting mechanism of a circular knitting machine, comprising a protective top plate, an upper cover, side plates, and a supporting bottom plate. The upper cover is fixed to the center of the upper part of the protective top plate, and the upper cover is uniformly provided with annular straight reinforcing ribs. The protective top plate is connected to the supporting bottom plate at the bottom via side plates, and the side plates are uniformly provided with ventilation holes. The protective top plate and the supporting bottom plate are fixed together by a connecting buckle structure, and their external structures match. This protective cover for the knitting mechanism of a circular knitting machine has a reasonable structural design. The cover is composed of a top plate, side plates, and a bottom plate, making installation and disassembly convenient. The use of plastic and aluminum alloy side plates results in a lightweight structure with good protective effect. Furthermore, both the top plate and the bottom plate are composed of four basic units, making splicing and installation more convenient and better protecting the knitting mechanism, thus promoting the development of the knitting machine industry. However, the above patent still has the following shortcomings: Although the knitting mechanism can be protected by the assembled protective top plate, top cover, side plate and supporting bottom plate, the protective cover needs to be removed when the yarn is replaced in the yarn feeding mechanism. The above protective cover is not easy to disassemble. Therefore, we propose a knitting machine heart with a protective structure. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a knitting machine heart with a protective structure.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A knitting machine core with a protective structure includes a knitting mechanism base. Multiple insert seats are mounted on the top surface of the knitting mechanism base. Each insert seat has multiple arc-shaped slots on its top surface and telescopic grooves on its outer sides. Multiple insertion holes are respectively formed on both sides of the inner cavity of each arc-shaped slot. Multiple springs are fixedly connected to the inner wall of the telescopic groove. Pull plates are fixedly connected to the ends of the springs. Multiple pins are fixedly connected to the inner side of the pull plates. The ends of the pins are movably sleeved into the insertion holes and the inner cavity of the arc-shaped slots. Pull blocks are fixedly connected to the outer side of the pull plates. A protective shell is provided on the top of the insert seats. An arc-shaped socket is fixedly connected to the bottom surface of the protective shell. The bottom end of the arc-shaped socket extends into the inner cavity of the arc-shaped slot and has multiple fixing holes. The pins penetrate the inner cavity of the fixing holes.

[0007] As a preferred embodiment of this utility model, a plurality of inner triangular supports are fixedly connected to the inner side of the bottom end of the protective shell, and a plurality of outer triangular supports are fixedly connected to the outer side of the bottom end of the protective shell. The outer triangular supports, inner triangular supports and the bottom surface of the protective shell are all in contact with the top surface of the insert.

[0008] As a preferred embodiment of this utility model, the top surface of the braiding mechanism base is provided with multiple screw holes, the insert seat is provided with multiple stepped holes, and bolts are respectively fitted on the multiple stepped holes, with the bottom end of the bolts threaded into the inner cavity of the screw holes.

[0009] As a preferred embodiment of this utility model, the top surface of the base of the weaving mechanism is provided with an installation hole, and the two ends of the insert seat are respectively provided with clearance grooves, and the clearance grooves and the installation hole are arranged concentrically.

[0010] In a preferred embodiment of this utility model, the inner wall of the arc-shaped slot and the side of the arc-shaped socket are fitted together.

[0011] In a preferred embodiment of this utility model, the outer diameter of the pin is equal to the inner diameter of the fixing hole and the insertion hole, respectively.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] In this invention, multiple insert seats are installed on the side of the knitting mechanism base, and multiple protective shells are installed on the multiple insert seats through the cooperation of arc-shaped slots, telescopic grooves, insertion holes, springs, pull plates, pins, arc-shaped sockets, and fixing holes. The multiple protective shells are combined to form a protective cover to protect the knitting mechanism base. In addition, when changing yarn on the yarn feeding mechanism, pulling the pull block causes the pin to disengage from the inner cavity of the insertion hole and the fixing hole, thereby releasing the fixation between the insert seat and the arc-shaped socket, and then removing the protective shell from the insert seat so that the yarn can be changed on the yarn feeding mechanism. This improves the practicality of the heart of the knitting machine with a protective structure. Attached Figure Description
