Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, in particular to a plush machine based on an improved knitting needle structure. Background Art

[0002] Artificial plush is a kind of plush fabric similar to animal fur formed by knitting artificial fibers. As people's aesthetic needs improve, they prefer plush fabrics with longer plush. The length of knitted plush fabric depends on the length of the silk thread between the upper knitting needle and the lower knitting needle at the lowest point.

[0003] In order to solve the technical difficulties in weaving extra-long plush fabrics, the Chinese patent with the authorization announcement number CN113684602B proposes a circular knitting machine and method for weaving extra-long plush fabrics. The device proposes a new knitting needle structure that combines a lower knitting needle with a spring. The structure can achieve the rapid descent of the lower knitting needle through the elastic force of the spring, thereby achieving the pulling of extra-long silk threads and avoiding the occurrence of broken threads. However, during the development and use of the above-mentioned equipment, the following problems exist: each lower knitting needle corresponds to a spring. Since the spring has a certain width, the expansion and contraction action of the spring during operation will inevitably cause lateral deformation. Therefore, adjacent springs are prone to collision and interference with each other, affecting the normal needle collection action of the lower knitting needle, so it needs to be improved.

DETAILED DESCRIPTION

[0020] The present invention is further described below through specific implementation methods.

[0021] Reference Figures 1 to 4 As shown, a plush machine based on an improved knitting needle structure includes: a knitting needle body 1, a traction line 2, a winding mechanism 3, a steering wheel 4, and a lower needle cylinder 5.

[0022] The knitting needle body 1 is mounted on the lower needle cylinder 5 .

[0023] The traction line 2 is a nylon line, a fluorocarbon line, or a polyethylene line.

[0024] The winding mechanism 3 includes a housing 31, a rotating shaft 32, and a scroll spring 33. The rotating shaft 32 and the scroll spring 33 are installed in the housing 31. One end of the traction line 2 is connected to the tail end of the knitting needle body 1, and the other end is connected to the rotating shaft 32. The scroll spring 33 applies a rotational force to the rotating shaft 32, and the rotational force drives the traction line 2 to be wound around the rotating shaft 32. Specifically, both ends of the rotating shaft 32 are rotatably connected to the housing 31, so that the rotating shaft 32 can rotate around its own axis. The scroll spring 33 is sleeved on the rotating shaft 32, the inner end of the scroll spring 33 is fixed to the rotating shaft 32, and the outer end of the scroll spring 33 is connected and fixed to the housing 31.

[0025] There are several groups of steering wheels 4, and the traction line 2 is guided by each steering wheel 4 and then connected to the knitting needle body 1 and the rotating shaft. In a specific embodiment, the steering wheel 4 includes a first steering wheel 41 and a second steering wheel 42, and the first steering wheel 41 is arranged at intervals on one side of the tail end of the knitting needle body 1. The traction line 2 is turned by the first steering wheel 41, and the traction line 2 between the knitting needle body 1 and the first steering wheel 41 is in a straight state and is on the extension line of the length direction of the knitting needle body 1. The shell 31 is provided with a wire hole 311, and the inside of the wire hole 311 corresponds to the position of the rotating shaft 32. The second steering wheel 42 is installed on the shell 31 and corresponds to the outside of the wire hole 311. After the traction line 2 is turned by the second steering wheel 42, it passes through the wire hole 311 and is wound on the rotating shaft 32. A mounting plate 312 is provided on the shell 31, and the shell is installed on one side of the inner wall of the lower needle cylinder 5 through the mounting plate 312. The lower needle cylinder 2 is provided with a channel 51 that penetrates inside and outside. The first steering wheel 41 is installed in the channel 51 and protrudes from the outer outlet of the channel 51 so that the first steering wheel 41 is located below the needle body 1, and the second steering wheel 42 is located at the inner outlet of the channel 51. The traction line 2 passes through the first guide wheel 41 and the second guide wheel 42 in sequence, and the traction line 2 between the first guide wheel 41 and the second guide wheel 42 passes through the channel 51.

[0026] The working principle of this plush machine based on improved needle structure is as follows:

[0027] The tail end of the knitting needle body 1 is connected to the traction line 2, and the traction line 2 always has a force to pull down the knitting needle body 1 under the action of the winding mechanism 3. The knitting needle body 1 is track-driven by a triangle. When the knitting needle body 1 needs to drop quickly during the knitting process, the winding mechanism 3 applies a downward pulling force to the knitting needle body 1 through the traction line 2 to achieve a rapid drop of the knitting needle body 1. When the knitting needle body 1 rises, it is driven by the triangular track and overcomes the elastic force of the spiral spring 33 of the winding mechanism 3, that is, the knitting needle body 1 pulls the traction line 2 upward. The specific knitting process mentioned above is a prior art, and reference may be made to the authorization publication number CN113684602B, a circular knitting machine and method for knitting extra-long plush fabrics, which will not be elaborated here.

[0028] The traction wire 2 used in the present application replaces the spring in the prior art. The traction wire 2 has a smaller diameter than the spring, so the traction wires 2 corresponding to adjacent lower knitting needles will not collide with each other, which can ensure the normal needle closing action of the knitting needle body 1. The winding mechanism 3 of the present application adopts a structure in which a spiral spring 33 cooperates with a rotating shaft 32, which can achieve a miniaturized design and high reliability.

[0029] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
