AI Technical Summary
After industrial hemp stalks are pressed and pounded, the fibers easily become entangled on the rollers, causing equipment blockage and affecting production efficiency. The existing roller structure lacks a targeted anti-entanglement structure, resulting in fiber damage and incomplete separation.
An anti-tangling stem crushing roller was designed, which adopts an anti-tangling wheel with a boss and an anti-tangling wheel with a groove meshing structure. The boss and groove cooperate to block the fiber entanglement and prevent the fiber from moving to both ends of the roller body. Combined with the straight teeth of the stem crushing roller, it can perform fine crushing and separation.
It effectively avoids fiber entanglement, improves the operational stability of the equipment and the quality of crushed stems, reduces equipment blockage and fiber damage, and increases production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery field especially relates to a kind of anti-winding roller structure for industrial hemp broken stem beating hemp procedure. BACKGROUND
[0002] After industrial hemp stem is experienced roll pressing beating, broken stem roller continues to finely break stem to make outer layer fiber (phloem) and internal hemp bone (xylem) loose separation, since stem fiber tenacity is strong and moisture content is high, it is easy to extend broken stem roller axial movement and wind on the shaft of both sides of roller body after collision extrusion, leading to equipment blockage, efficiency reduction, frequent shutdown cleaning also affect continuous production.
[0003] The existing broken stem tooth spiral arrangement roller body has guiding effect, makes hemp stem concentrate to roller body middle part, leads to the problem of too small middle part gap to cause hemp injury, overload, the broken stem tooth circumferentially evenly arranged roller body lacks targeted anti-winding structure, the broken stem roller is designed on the basis of broken stem tooth circumferentially evenly arranged roller body, and anti-winding structure can effectively avoid the problem that winding fiber clumps are formed on the shaft of both sides of roller, and the contact surface of roller body, broken stem tooth and stem is evenly stressed, which can effectively avoid fiber damage and incomplete separation, to improve the quality of broken stem. SUMMARY
[0004] The utility model aims at providing a kind of industrial hemp anti-winding broken stem roller, and broken stem roller is used to finely break industrial hemp stem, separate outer layer fiber (phloem) and internal hemp bone (xylem) of industrial hemp, and is used by the meshing of the anti-winding wheel with boss and the anti-winding wheel with groove at both ends of broken stem roller, blocks the fiber winding shaft head moving to both ends of roller body, solves the technical problem of existing roller body easy to block and fiber winding.
[0005] To achieve the above object, the technical scheme of the utility model is as follows: a kind of industrial hemp anti-winding broken stem roller, comprising: driving roller and driven roller, the driven roller includes the anti-winding wheel with boss, shaft pipe, broken stem straight tooth, driven shaft head, straight gear, a pair of anti-winding wheel with boss is welded in both ends of shaft pipe, and multiple groups of broken stem straight tooth are evenly welded in the circumference of shaft pipe, driven shaft head is welded in the outer end surface of anti-winding wheel with boss, and straight gear is keyed on driven shaft head, the driving roller includes the anti-winding wheel with groove, shaft pipe, broken stem straight tooth, driving shaft head, straight gear, transmission pulley, a pair of anti-winding wheel with groove is welded in both ends of shaft pipe, and multiple groups of broken stem straight tooth are evenly welded in the circumference of shaft pipe, driving shaft head is welded in the outer end surface of anti-winding wheel with groove, and straight gear, transmission pulley are sequentially keyed on driving shaft head.
[0006] When broken stem roller works, to achieve satisfactory working effect, the anti-winding wheel with boss is embedded and used by the meshing of the anti-winding wheel with groove, blocks stem axial movement path by the rolling contact of anti-winding wheel, and the gap between boss and groove is controlled in ≤1mm range. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 2 Figure 2 is a sectional view of the roller body of the broken stem roller.
[0009] The reference signs are explained as follows:
[0010] 1. Anti-winding wheel with boss, 2. shaft tube, 3. driven roller, 4. broken stem straight tooth, 5. driven shaft head, 6. straight tooth gear, 7. transmission pulley, 8. driving shaft head, 9. driving roller, 10. anti-winding wheel with groove. DETAILED DESCRIPTION
[0011] As shown in the figure, an industrial hemp anti-winding broken stem roller, comprising a driving roller 9, a driven roller 3, the driven roller 3 comprising an anti-winding wheel with boss 1, a shaft tube 2, broken stem straight teeth 4, a driven shaft head 5 straight tooth gear 6, a pair of anti-winding wheels with boss 1 are welded at both ends of the shaft tube 2, a plurality of groups of broken stem straight teeth 4 are evenly welded on the circumference of the shaft tube 2, the driven shaft head 5 is welded on the outer end face of the anti-winding wheel with boss 1, the straight tooth gear 6 is keyed connected with the driven shaft head 5, the driving roller 9 comprises an anti-winding wheel with groove 10, a shaft tube 2, broken stem straight teeth 4, a driving shaft head 8, a straight tooth gear 6, a transmission pulley 7, a pair of anti-winding wheels with groove 10 are welded at both ends of the shaft tube 2, a plurality of groups of broken stem straight teeth 4 are welded on the circumference of the shaft tube 2, the driving shaft head 8 is welded on the outer end face of the anti-winding wheel with groove 10, the straight tooth gear 6 and the transmission pulley 7 are sequentially keyed connected on the driving shaft head 8.
[0012] When the broken stem roller is working, in order to achieve satisfactory working effect, the anti-winding wheel with boss 1 is embedded in the anti-winding wheel with groove 8 for meshing use, and the gap between the boss and the groove is controlled within ≤1mm.
[0013] When working, the driving shaft head is driven to rotate by the transmission pulley, and then the driving roller is driven to rotate, the power is uniformly and synchronously transmitted to the driven roller through the meshing straight tooth gears, and the hemp stem fibers are finely broken and separated by the extrusion and scraping of the broken stem straight teeth and the shaft tube on the broken stem roller, the fed hemp stem can only move axially along the gap between the tooth top and the shaft tube, because the diameter of the anti-winding wheel is greater than the diameter of the tooth top, when the anti-winding wheel with boss meshes with the anti-winding wheel with groove, the moving path of the stem is blocked, therefore, from the stem feeding to the broken completion, the anti-winding wheel always limits the movement of the stem to both ends of the roller body.
