The invention relates to a method for impregnating and drying a continuous paper web (1) by means of a urea resin dissolved in water, and to a corresponding system. Such paper webs (1) are employed for example as furniture foil or floor laminate, wherein in the known art melamine resin is used exclusively for bonding to a substrate. This is relatively expensive. Therefore the object of the invention is to create a method in which the paper web (1) which is impregnated by means of urea resin can be bonded to the substrate with a high degree of operational reliability. Said object is achieved in that the temperature of the paper web (1) is determined separately in each of the drying zones (3.1, 3.2, 3.3, 3.4), that for each of the drying zones (3.1, 3.2, 3.3, 3.4) an amount and / or a temperature of the circulating air are regulated so that the maximum temperature of the paper web (1) is 99° C., and that exhaust air is extracted from a first one of the drying zones (3.1, 3.2, 3.3, 3.4) and fresh air is supplied to a last one of the drying zones (3.1, 3.2, 3.3, 3.4).

The invention relates to the field of spinning, in particular to a silkworm cocoon soaking device for spinning. The silkworm cocoon soaking device for spinning can improve silkworm cocoon water absorbing efficiency, shorten soaking time and save soaking water, and waste of water resources is avoided. The device structurally comprises a cylinder of a cylindrical hollow structure. A piston head is supported at the bottom in the cylinder through an electric hydraulic jack, the electric hydraulic jack penetrates through the bottom of the cylinder, the piston head is of a disc structure and placed horizontally, and the outer ring of the piston head is attached to the inner wall of the cylinder. A grid is supported in the middle of the inner wall of the cylinder, is of a grid structure and is obliquely arranged. A discharge hopper is supported on the outer side wall of the cylinder through a discharge door, the discharge hopper is communicated with the inside of the cylinder through the discharge door and is flush with the lower end of the grid, and the discharge hopper is of a U-type tank structure. The silkworm cocoon soaking device for spinning is high in use efficiency, low in use cost and suitable for the spinning silkworm cocoon soaking procedure.

The invention relates to a rotation lifting mechanism of a steel pipe quenching unit and a steel pipe quenching method. The steel pipe quenching method is that when the heated steel pipe is placed ona rotation supporting wheel, the rotation supporting wheel rotates at a speed lower than 10 rotations per minute to 15 rotations per minute; a compaction device distributed along the steel pipe direction closely presses the steel pipe; the rotation supporting wheel drives the steel pipe to rotate at a speed faster than 45 rotations per minute to 120 rotations per minute, and drives a frame beam 7to move downwards at a speed of 150 mm per second to 400 mm per second driven by a left lift cylinder 1 and a right lift cylinder 9 at the same time; the steel pipe is dipped into quenching medium ofa quenching tank, at this time, the inner spraying liquid flushes liquid to the internal of the steel pipe by an inner spraying nozzle always aiming to mouth of the steel pipe and the steel pipe innerwall quenching is carried out; until the temperature of the steel pipe is lower than 300 DEG C., the frame beam 7 is driven by both the left lift cylinder 1 and the right lift cylinder 9 and is lifted, at the same time, the compaction device is opened and a feeding overturn board 3 is turned to the material outlet location from a material receiping location to convey the steel pipe to an inclinedbench.

The invention discloses a kind of Cordyceps pharmaceutical equipment, the structure of which comprises a main frame, the front end of the main frame is fixed with a cleaning module for cleaning the Cordyceps, and the right end of the cleaning module is fixed with a container for drying and grinding the Cordyceps into powder. Putting module, the lower side of the holding module is equipped with a filling module for filling the powder, and the right side of the filling module is installed with a synthetic module for finally packaging the pills. The cleaning module includes a cylinder. This equipment passes through the cleaning module, The crushing module, holding module, pouring module, and synthesis module realize the cleaning, grinding, filling of pills, and pill packaging. Compared with traditional processing equipment for Cordyceps, this equipment reduces manpower and improves work efficiency. There is a better use of value.

The invention discloses a microwave dip dyeing method for willow twigs. The microwave dip dyeing method comprises the following steps: firstly, stewing the willow twigs; secondly enabling the stewed willow twigs to be subjected to alkali-H2O2 one-bath boiling; finally, enabling the materials obtained in the second step to be subjected to pretreatment by a chitosan acid solution; components like xylogen in the willow twigs are degraded, so that the rigidity of the willow twig structures is reduced, and the willow twigs are prevented from cracking under the mechanical force action and a thermal action; chitosan is added to play a certain modifying effect on willow twig fibers, the dye fixation is higher; besides, an anti-cracking dyeing auxiliary is added into the dye, the dyeing power of the dye on the surfaces of the willow twigs is improved, a protective film is formed on the surfaces of the willow twigs, a continuous, flatted and smooth coloring film is formed, the dye can quickly immerse into the willow twig fibers by microwave treatment, and an everlasting and stable dyeing effect is achieved.

The invention discloses a method for preparing an electrostatic dry impregnated fiber felt, which comprises the following main steps: (1) two kinds of different fiber yarns are chopped, blended, and settled for mesh paving to form a fluffy and evenly-blended blank felt; (2) resin powder is scattered on the surface of the blank felt according to the mixture ratio; (3) the blank felt is subjected to dry impregnation under the action of an electric field through an impregnating machine; (4) an interface and the bottom of the blank felt are paved with non-woven fabrics, and the double-sided needling is performed for reinforcement; and (5) the felt is formed through edge cutting and rolling. The method has the advantages that the method overcomes the technical defects existing in the prior powder scattering process, realizes the even impregnation of the resin powder to the fiber felt, has small investment and low energy consumption, does not use solvents and adhesives, relates to broad industry products, is suitable for industrialized production, is more scientific and reasonable compared with the prior chopped strand felt preparation technology, and provides a novel process route for manufacturing thermoplastic reinforced fiber felts.
