Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the figure, a special rolling device for bark of Eucommia comprises a frame 16, and three pairs of pressure rollers are arranged at horizontal intervals on the frame 16, which are respectively the first pair of pressure rollers 3, the second pair of pressure rollers 12 and the first pair of pressure rollers. The third pair of pressure rollers 25 .

[0020] The three pairs of pressure rollers are all arranged in parallel up and down, and the pressure rollers located above are all movable rollers, and each movable roller is connected with two hydraulic cylinders 6, and the three movable rollers are respectively driven by their respective hydraulic systems. The cylinder 6 is driven to realize the movement of the movable roller into and out of the roller. Accumulators 2 are respectively provided in the three hydraulic ...

Abstract

The invention provides a special rolling device for cortex eucommiae barks. The special rolling device comprises a rack, wherein three pairs of compression rollers are arranged on the rack and are arranged in parallel up and down; a supporting rolling shaft is arranged between the two adjacent pairs of the compression rollers; axial rectangular teeth are arranged on the outer circumferences of the first pairs of compression rollers; triangular-pyramid-shaped bulges I are arranged at the top ends of the rectangular teeth; peripheral rectangular convex edges are arranged on the outer circumferences of the second pairs of compression rollers; triangular-pyramid-shaped bulges II are arranged at the top ends of the convex edges; cutting-off tools with saw-tooth-shaped axial cross sections are arranged on the outer circumferences of the third pairs of compression rollers; and cutting edges of the cutting-off tools are smoothened. The special rolling device can be used for rolling the cortex eucommiae barks and carrying out puncturing and cutting-off breakage treatment on a wood layer, so that the non-rubber wood layer can be sufficiently crushed and the original physical state and physical performance of cortex eucommiae rubber are kept; and the foundation is laid for improving the integrity of the cortex eucommiae rubber and keeping the high rubber extracting rate.

Description

technical field [0001] The invention relates to a production equipment for extracting eucommia gum, in particular to a special rolling device for eucommia bark. Background technique [0002] Eucommia ulmoides is a precious tree species unique to my country. Eucommia ulmoides gum contained in eucommia ulmoides, as a natural rubber, has the advantages of high insulation and corrosion resistance. It is a high-quality material for manufacturing submarine cables. Medicine container and excellent raw material for dental fillings. Eucommia gum can also be used to make medical splints, automobile tires, shape memory materials, temperature detection materials, modified plastics and other rubber products, so it has broad application prospects. [0003] There are two types of existing methods for extracting Eucommia gum from Eucommia ulmoides, one of which is: the raw material bark of Eucommia ulmoides is fully fermented and then boiled with a strong alkali aqueous solution, and then s...
