The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1 to 4, the yarn kneading mechanism of the utility model comprises a casing 1, a yarn kneading main shaft 2, a yarn kneading movable cutter 3 and a yarn kneading fixed cutter 4, wherein one end of the casing 1 is provided with a yarn kneading feed port 11, the other end is provided with a yarn kneading discharge port 12, the yarn kneading movable cutter 3 is provided with yarn kneading movable cutter teeth 31, the yarn kneading fixed cutter 4 is provided with a plurality of yarn kneading fixed cutter teeth 41 matched with the yarn kneading movable cutter teeth 31, the yarn kneading main shaft 2 is rotatably arranged in the casing 1, and the yarn kneading fixed cutter 4 is arranged at the bottom of the casing 1. The structure is the same as that of the traditional yarn kneading mechanism, but the yarn kneading movable cutter 3 of the traditional yarn kneading mechanism is connected with the yarn kneading main shaft through the connecting rod, the connecting rod is arranged on the yarn kneading main shaft by adopting a cross-shaped structure, and a channel for passing through materials is formed between the yarn kneading movable cutter and the yarn kneading main shaft, so that part of materials always pass through the channel formed between the yarn kneading movable cutter and the yarn kneading main shaft and do not pass through between yarn kneading fixed cutter teeth, and the processed material has insufficient filamentization rate. In order to solve the above problems, the yarn kneading mechanism of the present utility model is characterized in that the yarn kneading spindle 2 is sleeved with a sleeve 5 fixedly connected with the yarn kneading spindle 2, the outer surface of the sleeve 5 is continuously free of through holes, thereby forming a blocking surface for preventing materials from passing between the yarn kneading movable blade 3 and the yarn kneading spindle 2, and the yarn kneading movable blade 3 is mounted on the outer surface of the sleeve 5.
Specifically, the kneading and moving knife 3 can be mounted on the outer surface of the sleeve 5 in a conventional fixed connection manner such as bolting, welding and the like; the sleeve 5 can be fixedly connected with the yarn kneading main shaft 2 by adopting a conventional fixed connection mode such as welding, bolt connection and the like.
According to the utility model, after the wire kneading main shaft 2 is provided with the sleeve 5, the wire kneading movable knife 3 is arranged on the outer surface of the sleeve 5, and a blocking surface for preventing materials from passing between the wire kneading movable knife 3 and the wire kneading main shaft 2 is formed on the outer surface of the sleeve 5, so that the materials can only pass below the outer surface of the sleeve 5, namely only pass between the wire kneading fixed knife teeth 41 of the wire kneading fixed knife 4, and therefore, the materials can be kneaded better without increasing the rotating speed of the wire kneading main shaft, and the material filamentization rate can be increased.
As shown in fig. 2, two ends of the sleeve 5 are respectively provided with a sealing plate 51, the sealing plates 51 can prevent materials from entering the sleeve 5 from two ends of the sleeve 5, and the sleeve 5 is fixedly connected with the wire kneading main shaft 2 through the sealing plates 51.

The cross section of the sleeve 5 may be circular, regular polygonal in configuration, etc. In theory, when the cross section of the sleeve 5 is circular, the effect of improving the material filamentization rate of the thread kneading mechanism is optimal, but because the outer surface is arc-shaped when the sleeve is circular, the thread kneading movable knife 3 is inconvenient to install, and therefore, the cross section of the sleeve 5 can be provided as a regular polygon structure. Thus, the outer surface of the sleeve 5 is provided with a plane, and the yarn kneading knife 3 is more convenient to install. When the cross section of the sleeve 5 is of a regular polygon structure, the number of edges of the regular polygon can be set to the maximum according to the installation condition of the yarn kneading movable cutter 3, so that adverse effects on the yarn kneading mechanism can be reduced as much as possible.

Referring to fig. 3 and 4, the wire kneading and fixing cutter teeth 41 of the wire kneading and fixing cutter 4 of the wire kneading mechanism can be parallel to the plane 7 perpendicular to the axis of the wire kneading main shaft 2; or inclined with respect to a plane 7 perpendicular to the axis of the wire-kneading spindle 2. When the kneading wire stationary cutter teeth 41 are inclined relative to the plane 7 perpendicular to the axis of the kneading wire main shaft 2, since the projection of the movement locus 9 of the moving blade on the horizontal plane is parallel to the plane 7 perpendicular to the axis of the kneading wire main shaft 2, the distance between the kneading wire stationary cutter teeth 41 and the kneading wire stationary cutter teeth 41 is changed when the kneading wire stationary cutter teeth 41 pass through the kneading wire stationary cutter teeth 41, so that the material Yi Kaji is at the bottom of the kneading wire stationary cutter teeth, namely, the place where the kneading wire moving cutter teeth cannot act, the machine load is increased, and after the machine is used up, it is troublesome to clean the stuck material in the gap between the stationary cutter teeth. Thus, optimally, the wire-kneading stationary cutter teeth 41 are parallel to the plane 7 perpendicular to the axis of the wire-kneading spindle 2.
In some embodiments, the wire-kneading and fixing knives 4 are in a row. Referring to fig. 1 and 4, in order to improve the yarn kneading effect, the yarn kneading stationary knives 4 are arranged in a plurality of rows, the yarn kneading stationary knives 4 are arranged along the direction from the yarn kneading feed inlet 11 to the yarn kneading discharge outlet 12, and the yarn kneading stationary knife teeth 41 of the yarn kneading stationary knives 4 in two adjacent rows are staggered. The wire kneading and fixing cutters 4 can also be arranged in one row or a plurality of rows, and in fig. 1, the wire kneading and fixing cutters 4 are arranged in two rows and symmetrically arranged on the sleeve 5.
In order to further increase the filamentization rate, in the embodiment of the present utility model, the thread-kneading movable cutter teeth 31 and the thread-kneading fixed cutter teeth 41 are provided with thread-kneading blade teeth 311. In some embodiments, the direction of extension of the wire kneading blade teeth 311 is arranged in a direction perpendicular to the sides of the respective wire kneading blade teeth.

The rubbing edge teeth 311 are obliquely arranged with the corresponding rubbing edge teeth, that is, the rubbing edge teeth 311 on the rubbing moving edge teeth 31 are obliquely arranged with the rubbing edge teeth (see fig. 5), and the rubbing edge teeth 311 on the rubbing fixed edge teeth 41 are obliquely arranged with the rubbing fixed edge teeth. When the yarn kneading blade teeth 311 are obliquely arranged, the material is more easily scratched, and the yarn kneading mechanism is beneficial to improving the yarn-breaking rate. In addition, especially, after the thread-kneading fixed cutter teeth 41 are parallel to the plane 7 perpendicular to the axis of the thread-kneading main shaft 2, the thread-kneading cutter teeth 311 are obliquely arranged, so that the resistance of the thread-kneading fixed cutter teeth 41 to materials is smaller, and the reduction of the mechanism load is facilitated.
When the screw kneading blade teeth 311 are obliquely arranged, especially after the screw kneading blade teeth 311 on the screw kneading movable blade teeth 31 are obliquely arranged, the forward pushing action of the screw kneading movable blade teeth on the materials can be reduced, therefore, in order to timely discharge the materials in the shell, the screw kneading mechanism is further provided with the scraping plates 6, the scraping plates 6 are arranged on the outer surface of the sleeve 5 and positioned on one side of the screw kneading movable blade 3, and the scraping plates 6 are in one-to-one correspondence with the screw kneading movable blade teeth 31 of the screw kneading movable blade 3 and are arranged in a staggered manner. The scraping plates 6 are corresponding to and staggered with the yarn kneading and moving cutter teeth 31 of the yarn kneading and moving cutter 3, namely: the projection of the line connecting the kneading blade teeth 31 with the corresponding scrapers 6 on the horizontal plane is not parallel to the plane 7 perpendicular to the axis of the kneading spindle 2 (see fig. 3, 4). In this way, the scraper 6 can push out the materials by means of the scraper 6 when the scraper 6 rotates along with the yarn twisting main shaft and passes through the yarn twisting fixed cutter teeth 41. Referring to fig. 6, the end surface of the scraper 6 may be provided with straight teeth 61, and the straight teeth 61 may act on the material during discharging, so as to further improve the wire kneading effect.
