Abstract

The invention discloses an automatic flax bundle splitting device with uniform and accurate control of flax bundles. The automatic flax bundle splitting device comprises an unwinding mechanism, a feeding mechanism and a bundle splitting mechanism; the feeding mechanism includes a continuous moving conveyor track, needle belts are respectively arranged on both sides of the conveyor track continuously along the moving direction of the conveyor track, a continuous tear separation area matched with the bundle splitting mechanism is formed on the conveyor track between the two needle belts, the bundle splitting mechanism includes a plurality of bundle splitting rollers which are continuously arranged in the direction of movement of unrolled scutched flax to tear and split the unrolled scutched flax to form a number of continuous and uniformly loose flax bundles, multiple annular needle belts are uniformly distributed on the bundle splitting rollers, and a buffer mechanism and a weighing device connected with the buffer mechanism and used for quantitatively weighing the continuous and uniformly loose flax bunches are arranged at the output end of the bundle splitting mechanism. By the arrangement, the problem of uneven bundle splitting in traditional unit flax bundles is solved, working efficiency is improved, and labor intensity is reduced.

Description

technical field

[0001] The invention relates to the field of flax spinning equipment, in particular to an automatic flax splitting device with uniform, precise and controllable flax bundles. Background technique

[0002] Flax is a pure natural fiber, which is more and more valued by human beings because of its remarkable characteristics such as sweat absorption, good air permeability and harmlessness to human body. The flax fiber exists in the bast tissue of the hemp stem. It is soaked and degummed to remove part of the gum, so that the bonded fiber bundles are partially loosened, and then processed by rolling and hemp to make "beaten hemp". After the bunches are combed, they are further loosened and separated into technical fibers suitable for spinning, that is, combed into hemp. The hemp fibers that are now sent to the mill are rather coarse fiber bundles. The physical indicators such as fiber strength and length are extremely uneven, and the fibers also contain short an...

Examples

Embodiment 1

[0030] Such as figure 1 , 2 , 3, 4, 5, and 6, a flax automatic splitting device with uniform, precise and controllable flax bundles, including an uncoiling mechanism 2 for automatically launching the flax round bales 1, and a flax round bale The feeding mechanism 4 for transporting the rolled hemp 3 after the package 1 is expanded also includes a beam splitting mechanism 9 for automatically splitting the expanded hemp 3 .

[0031]The feeding mechanism 4 includes a continuously moving conveying crawler belt 5, which is driven by the installed driving roller 6 and driven roller 7 to perform continuous and uniform circular motion. Along the moving direction of the conveyor belt 5, needle belts 8 for applying a quasi-constraining force to the unfolded hemp 3 and fixing them on the surface of the conveyor belt 5 are continuously arranged on both sides of the conveyor belt 5. A continuous tearing partition 10 cooperating with the beam splitting mechanism 9 is formed on the conveyi...

Embodiment 2

[0038] The similarities between this embodiment and Embodiment 1 will not be repeated, and the difference is that: figure 1 As shown, at the discharge port 26 of the beam splitting mechanism 9, a crushing mechanism 27 for secondary tearing and splitting of the continuous and uniform loose tow 11 formed by tearing and splitting is provided. Roll-off mechanism 27 comprises the second conveying crawler belt 28 that is arranged along the conveying direction of making hemp, and along the conveying direction of the second conveying crawler-belt 28, a plurality of rolling-off rollers 29 are arranged successively above the second conveying crawler belt 28, in each A tearing and grinding zone for performing secondary tearing and splitting of the continuous and uniform loose hemp bundle 11 is formed between the rolling roller 29 and the second conveying crawler belt 28 .

[0039] Due to the different thicknesses and densities of the beating hemp bundles 1, the density of the continuous ...
