Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, and in particular to a sleeve that is easy to install on a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] Existing circular knitting machines require coaxiality and parallelism between the sleeves and the frame during operation. For example... Figure 1 The diagram shows the existing installation structure of a large circular knives, including a sleeve, a core, and bead discs. The structure includes a frame 1', a large cauldron mounted on the frame 1', a sleeve 2' connected to the cauldron, a core 3' at the lower end of the sleeve 2', and a bead disc 4' at the bottom of the sleeve 2'. During installation, when the core is fitted onto the sleeve, it needs to be tapped and adjusted to ensure coaxiality and parallelism between the core and the sleeve before installing the bead discs. However, because the coaxiality and parallelism of the sleeve and bead discs are adjusted during installation, the bead discs may not match the parallelism of the sleeve when installed at the bottom. Therefore, grinding the surface of the bead discs is necessary to install them onto the sleeve. While this meets the installation requirements, grinding the bead discs is extremely labor-intensive, inefficient, and detrimental to installation. This invention addresses this problem. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a sleeve with a simple structure and convenient installation, which is easy to install on a circular knitting machine.

[0005] To achieve the above objectives, the present invention provides a sleeve that is easy to install on a circular knitting machine, comprising a frame and a sleeve mounted on the frame. The sleeve has a core, and a beaded disc is located below the core at the bottom of the sleeve. A first connecting disc is located at the lower end of the sleeve, and the core is mounted on the first connecting disc. A first fixing device is provided between the first connecting disc and the core. A second connecting disc is located at the bottom of the sleeve, and the beaded disc is mounted on the second connecting disc. A second fixing device is provided between the first connecting disc and the beaded disc.

[0006] A further improvement is that the first fixing device includes a plurality of first fixing bolts, which are arranged in a circular array and locked between the core and the first connecting plate to fix the core to the first connecting plate.

[0007] A further improvement is that the second fixing device includes a plurality of second fixing bolts, which are arranged in a circular array and locked between the bead disc and the second connecting disc to fix the bead disc on the second connecting disc.

[0008] A further improvement is that a first connecting groove is provided at the lower end of the first connecting plate, and the core is disposed in the first connecting groove.

[0009] A further improvement is that a second connecting groove is provided at the lower end of the second connecting disc, and the bead disc is disposed in the second connecting groove.

[0010] The advantages and beneficial effects of this utility model are as follows:

[0011] The structure is simple, easy to install, and highly efficient. Compared to the traditional method of fitting onto a sleeve, this technical solution is not only easier to install, but also allows for fine-tuning of parallelism via the first and second fixing bolts. Furthermore, the independent connection of the core and bead discs via the first and second connecting discs ensures that parallelism adjustments are made by adjusting the flatness of each disc separately, without interference. This simplifies the installation and adjustment of the core and bead discs, significantly improving worker efficiency. Attached Figure Description

[0014] Figure 3 This is an enlarged structural diagram of point A in this utility model. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figures 2-3As shown, a sleeve that is easy to install on a circular knitting machine includes a frame 1, a sleeve 2, a core 3, and a beaded disc 4 disposed on the frame 1. The sleeve 2 is provided with the core 3, and the bottom of the sleeve 2 is provided with the beaded disc 4 below the core 3. The lower end of the sleeve 2 is provided with a first connecting disc 5, and the core 3 is disposed on the first connecting disc 5. A first fixing device is provided between the first connecting disc 5 and the core 3. The bottom of the sleeve 2 is provided with a second connecting disc 8, and the beaded disc 4 is disposed on the second connecting disc 8. A second fixing device is provided between the first connecting disc 5 and the beaded disc 4.

[0017] Specifically, the first fixing device includes a plurality of first fixing bolts 6, which are arranged in a circumferential array between the core 3 and the first connecting plate 5 to fix the core 3 onto the first connecting plate 5.

[0018] Specifically, the second fixing device includes a plurality of second fixing bolts 9, which are arranged in a circular array between the beaded disc 4 and the second connecting disc 8 to fix the beaded disc 4 onto the second connecting disc 8.

[0019] During installation, the core 3 is directly locked onto the first connecting plate 5, and then the beaded disc 4 is locked onto the second connecting plate 8. The core 3 is locked onto the first connecting plate 5 using the first fixing bolt 6. Compared to the traditional method of fitting it onto the sleeve 2, this not only facilitates installation but also allows for fine-tuning of parallelism through the first fixing bolt 6. Similarly, the beaded disc 4 is locked onto the second connecting plate 8 using the second fixing bolt 9. This not only facilitates the installation of the beaded disc 4 but also allows for fine-tuning of parallelism through the second fixing bolt. Furthermore, the core 3 and beaded disc 4 are independently connected via the first connecting plate 5 and the second connecting plate 8, respectively. Adjusting parallelism only requires adjusting the flatness of the first connecting plate 5 and the second connecting plate 8, without interference between them, making the installation and adjustment of the core 3 and beaded disc 4 even simpler.

[0020] To facilitate the installation and connection of the core 3 and the first connecting plate 5, a first connecting groove 7 is provided at the lower end of the first connecting plate 5, and the core 3 is disposed in the first connecting groove 7.

[0021] To facilitate the installation and connection of the second connecting plate 8 and the bead plate 4, a second connecting groove 10 is provided at the lower end of the second connecting plate 8, and the bead plate 4 is disposed in the second connecting groove 10.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
