In one embodiment of the above technical solution, adjacent pairs of carding drums are arranged in a staggered manner, and the engagement position of the rear pair of carding drums is lower than the engagement position of the front pair of carding drums; the rotational movement of a pair of combing rollers engaged up and down has a speed difference, and the linear speed of the lower combing roller is greater than that of the upper combing roller.
According to the invention, a plurality of rows of carding members are uniformly distributed on the outer wall of the carding roller, and carding strips are arranged on the inclined side wall of the carding body, so that the carding body and the carding strips form a toothed plate structure, splayed carding gaps are formed between the adjacent carding members in the same row, and as the carding roller rotates, the crushed hemp stalks are continuously extruded by the carding gaps on the carding roller to be carded to remove hemp scraps. The carding component has the functions of extruding, scraping and beating the hemp stalks, and scraping and beating are realized through carding strips, so that the strength of the carding component is much smaller than that of a beating plate in the prior art, and the damage to hemp fibers is effectively reduced. Simultaneously, the stalk after the garrulous stem has increased and has scraped and beaten and squeeze the area through the effect of slope carding body lateral wall, makes the hemp bone comb cleaner.
Therefore, the invention can improve the hemp peeling efficiency and the hemp peeling quality through the improvement of the carding component, so that the hemp scraps and impurities attached to the hemp fibers are thoroughly removed, thereby obtaining clean and high-hemp-length fibers. That is, the invention not only has high hemp peeling efficiency, but also has the advantage of improving the long hemp rate of the fiber.

Detailed Description
As shown in fig. 1 and 2, the outer wall of the carding roller 1 of the industrial hemp fiber carding device disclosed in the embodiment is uniformly provided with a plurality of rows of carding members 2, and the outer wall of the carding roller 1 is uniformly provided with a plurality of rows of carding members 2 along the axial direction. In order to improve the hemp dust carding effect, carding members 2 which are engaged with the outer walls of the drums are arranged in a staggered manner.
As shown in fig. 3 to 6, the carding member 2 includes a carding body 21 and a carding strip 22, the cross section of the carding body in this embodiment is isosceles triangle, the height is about 40mm, the carding strip is a semi-cylinder with the length of the carding body, the arc surface of the carding strip is welded to the middle parts of two waist plates of the carding body vertically outwards, and the cooperation of the carding body and the carding strip makes the carding member form a toothed plate structure. Each carding body is arranged tangentially with the top of its cross section towards the direction of rotation of the carding drum. Splayed carding gaps are formed between adjacent carding members 2 in the same row on the carding drum 1.
In order to ensure the effect of carding the hemp scraps, the height of the carding body is preferably about 40mm, and the meshing depth of the carding members of the two carding rollers is about 20 mm.
