The invention discloses a method for endless rolling of sectional material and rod and wire material and a flexible connecting device thereof, which realize seamless connection of all-line rolling and continuous molding from crystallizers to finished products. The invention comprises that a flexible connecting rolling mill device is arranged on a conventional continuous casting-continuous rollingproduction line, wherein the flexible connecting rolling mill device is in three forms: one consists of a soft pressure lower roll system; one consists of a high pressure lower roll mechanism; and one consists of the soft pressure lower roll system and the high pressure lower roll mechanism together. The flexible connecting rolling mill device is arranged between the crystallizers and the conventional continuous rolling mills in one of the three forms. The method for the endless rolling of the sectional material and rod and wire materials and the flexible connecting device thereof save three processes of continuously cast bloom cutting, secondary heating and welding, realize the seamless connection and flexible connection between the continuous casting and continuous rolling, shorten the production flow and the production line length, simplify the operation, and provide a new way for the metallurgy production to realize the energy and resource conservation, reduce the carbon emission,reduce the cost and improve the product quality and competitiveness.

The invention provides a dyeing and finishing process of an antipilling-antistatic yarn and an automatic impregnator for the dyeing and finishing process, belongs to the technical field of textile machinery, and solves the problems of insufficient impregnation of yarns and shortage of the dyeing and finishing process with antipilling and antistatic performance. The dyeing and finishing process for the yarn with waterproof properties comprises the following steps: A, inspecting blanks, B, finishing, C, putting into a vat, D, carrying out hank dyeing; E, preparing an antipilling-antistatic staining solution, F, carrying out impregnation, G, drying, H, inspecting quality, I, packing, and J, putting in storage. The automatic impregnator for the dyeing and finishing process comprises a working table, a hank knotting cylinder is arranged on one side of the working table, a sliding positioning mechanism which can enable the hank knotting cylinder and the working stable to relatively slide is arranged between the hank knotting cylinder and the working stable, an upright column is fixed on the working stable, and a lifting mechanism which can enable a compressing plate to move up and down is arranged between the upright column and the compressing plate. The automatic impregnator disclosed by the invention has the advantages of high dyeing efficiency, sufficient impregnation and the like.

The invention discloses an ordered harvester for closely planted vegetables. The ordered harvester is characterized in that an annular rail and a harvesting trolley are arranged at the front end of the harvester through a support, the harvesting trolley can move along the outer edge of the annular rail, the harvesting trolley comprises a base, the wide edge of the base is vertical to the advancingdirection of the harvesting trolley on the annular rail when the harvesting trolley moves along the annular rail, a double-row cutter is arranged at the front end of the wide edge of one end of the base, a row of conveying wheels is sequentially arranged on the base and at the rear end of the double-row cutter to form a conveying platform, a telescopic gripper structure whose width is matched with the width of the conveying platform is further arranged at the rear of the double-row cutter and on the conveying platform, and the gripper structure is further connected with a mechanical arm fixedto the harvesting trolley. The ordered harvester has the advantages that the ordered harvester is ingenious in structure, batch harvesting and transferring of the closely planted vegetables are achieved, ordered harvesting is achieved, high harvesting efficiency is achieved, later neatening is omitted, scratch damage to unharvested vegetables in front can be avoided, and the harvester is high inpracticality and worthy of popularization.

The invention relates to the production technology of an anti-ultraviolet and moisture-absorption quick-dry fabric. The technology is characterized by firstly, adopting a polyester resin and an addition agent to melt, extruding, and pelletizing to make polyester chips; then, through a spinning technology, forming a fine denier polyester staple fiber; and then, through siro spinning and weaving technologies, an alkali decrement technology and the like, making a finished product. The anti-ultraviolet and moisture-absorption quick-dry fabric has advantages that a lot of micropores and channels are distributed on a surface so that the fabric has a high capillary effect; sweat can be quickly transferred to an outer groove through the micropores so as to form a moisture-absorption quick-dry effect; and an environment-friendly ultraviolet absorbent, a shielding agent and the polyester chips are fused, and a high-performance anti-ultraviolet and moisture-absorption quick-dry fabric after a special spinning technology is formed.

The invention discloses an automatic sheet shearing machine; an upper drive feeding roller and an upper driven feeding roller are mounted above a workbench; a lower drive feeding roller and a lower driven feeding roller are mounted below the workbench; the upper drive feeding roller is driven by a feeding motor; the upper drive feeding roller and the lower drive feeding roller are in synchronous transmission connection; a punch mounting base is mounted behind the workbench; a punch is arranged in the punch mounting base in a sleeved manner; under the action of a power device, the punch can horizontally move back and forth; a convex mould is mounted at the front end of the punch; a concave mould matched with the convex mould is arranged at the front end of the convex mould; the concave mould is mounted on the workbench; a magnetic sheet product collecting channel is arranged at the rear end of a cavity structure; a rack is mounted at the side of the convex mould through a linkage plate; and the rack is engaged with a one-way gear at the outer end of the upper drive feeding roller. The automatic sheet shearing machine is applied, so that automatic punching of soft magnetic sheets can be realized, and therefore, magnetic sheet products obtained by punching are automatically ordered.
