Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a knitting machine needle cylinder which is easy to clean. Background Art

[0002] Knitting machine: A machine for knitting "knitted fabrics". The first hand-cranked knitting machine was invented by William Lee, an English clergyman in 1589. With the invention of the electric motor in the 1870s, hand-cranked knitting machines were replaced by high-speed electric knitting machines. The needle cylinder is the device that mounts the knitting needles and sinkers.

[0003] Existing patent: CN209602729U, discloses a needle cylinder of a circular knitting machine, including an upper needle cylinder and a lower needle cylinder, which are fixed as a whole; a plurality of first grooves are evenly distributed on the upper needle cylinder, a plurality of inserts are embedded on the circumferential wall of the lower needle cylinder, all the inserts are distributed at equal circumferential angles on the circumferential wall of the lower needle cylinder, and the gap between two adjacent inserts forms a second groove.

[0004] The above patent or existing knitting machine needle cylinder has the following problems:

[0005] After long-term use, the inside of the existing knitting machine needle cylinder is prone to dirt due to the accumulation of cotton wool, so it needs to be cleaned regularly. However, the internal space of the existing knitting machine is relatively limited, so it is inconvenient to clean the needle cylinder. Utility Model Content

[0006] The utility model aims to provide a knitting machine needle cylinder which is easy to clean, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a knitting machine needle cylinder that is easy to clean, comprising a cylinder, a needle groove is opened on the cylinder, a docking seat is arranged at the bottom of the cylinder, an inner cylinder structure is arranged inside the cylinder, the inner cylinder structure comprises a supporting pad, a supporting pad is arranged at the lower end of the cylinder, an inner cylinder sleeve is assembled inside the cylinder, a groove is arranged inside the inner cylinder sleeve, and a pressure ring is arranged at the upper end of the cylinder.

[0008] Preferably, an opening is provided on the inner side of the pressure ring.

[0009] Preferably, the inner side of the upper end of the pressure ring is an inclined surface, and the outer ring of the upper end of the pressure ring expands outward.

[0010] Preferably, when the inner sleeve is inserted into the cylinder body and placed on the support pad, the inner sides of the inner sleeve and the support pad are in the same plane, and when the pressure ring is installed in the cylinder body, its inner side is in the same plane as the inner side of the inner sleeve.

[0011] Preferably, a convex ring is provided at the top of the inner sleeve, and a notch is provided at the bottom of the pressure ring.

[0012] Preferably, a pressure pad is installed inside the recess, and the outer diameter of the pressure pad is smaller than the outer diameter of the pressure ring.

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

[0014] When it is necessary to clean the inside of the cylinder, the pressure ring is rotated. Since the pressure ring is threadedly connected to the upper end of the cylinder, the pressure ring will move upward when it is rotated, and then it is taken out, thereby releasing the limit fixation of the inner sleeve, and then the inner sleeve can be taken out through the groove. The taken out inner sleeve is separated from the cylinder, and then the dirt inside the inner sleeve is cleaned, so that the inner sleeve can be easily disassembled and cleaned, avoiding the problem of inconvenience in cleaning due to the limited internal space of the knitting machine when dirt accumulates inside the cylinder.

[0020] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0021] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a knitting machine needle cylinder which is easy to clean, comprising a cylinder body 1, a needle groove 2 is provided on the cylinder body 1, the needle groove 2 is used to install the knitting needle, a docking seat 3 is provided at the bottom of the cylinder body 1, which is used to dock the cylinder body 1 so that it can be installed on the knitting machine, and an inner cylinder structure 4 is provided inside the cylinder body 1.

[0022] See also Figure 1 , Figure 3 and Figure 4The utility model provides a knitting machine needle cylinder that is easy to clean. The inner cylinder structure 4 includes a support pad 41. The support pad 41 is integrally formed at the lower end of the cylinder body 1. The inner cylinder sleeve 42 is assembled inside the cylinder body 1. When the inner cylinder sleeve 42 is installed inside the cylinder body 1, it is placed on the top of the support pad 41. At the same time, the inner side surface of the inner cylinder sleeve 42 and the inner side surface of the support pad 41 are in the same plane. A groove 43 is opened inside the inner cylinder sleeve 42. The groove 43 can facilitate the staff to take out the inner cylinder sleeve 42. A pressing ring 44 is provided at the upper end, and the pressing ring 44 is threadedly connected to the upper end of the cylinder 1. An opening 441 is integrally formed at the inner upper end of the pressing ring 44 to facilitate the staff to rotate the pressing ring 44. The inner side of the upper end of the pressing ring 44 is an inclined surface, which is convenient for knitted cloth to be put down. The outer circle of the upper end of the pressing ring 44 expands outward and can be pressed on the cylinder 1 to avoid the lint being stuck in the seam. When the pressing ring 44 is installed in the cylinder 1, its inner side is in the same plane as the inner side of the inner sleeve 42, which reduces the abruptness and the accumulation of lint in the morning.

[0023] A convex ring 421 is provided at the top of the inner sleeve 42, and a notch 422 is provided at the bottom of the pressure ring 44. When the pressure ring 44 is installed in the cylinder body 1, the convex ring 421 will be inserted into the notch 422, so that the installation of the inner sleeve 42 is more stable, and a pressure pad 423 is installed inside the notch 422. The pressure pad 423 will seal the connection between the inner sleeve 42 and the pressure ring 44 to improve the sealing performance. The outer diameter of the pressure pad 423 is smaller than the outer diameter of the pressure ring 44, which can prevent the pressure pad 423 from expanding under force and being squeezed on the inner side of the cylinder body 1, which is not convenient for subsequent disassembly;

[0024] When it is necessary to clean the inside of the cylinder 1, the staff rotates the pressure ring 44. Since the pressure ring 44 is threadedly connected to the upper end of the cylinder 1, the pressure ring 44 will move upward when it is rotated, and then it will be taken out. Then the staff can take out the inner sleeve 42 through the groove 43, and then clean the inside of the inner sleeve 42, so that the inner sleeve 42 can be easily disassembled and cleaned, avoiding the problem of inconvenience in cleaning when dirt accumulates inside the cylinder 1 due to the limited internal space of the knitting machine.

[0025] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
