The utility model relates to wire drawing machine pay -off technical field, and disclose a wire drawing machine pay -off device with line pressing structure, including bottom plate, pressure mechanism and abutting mechanism, the upper surface fixed connection of bottom plate has the support plate for supporting pay -off roll, the top of support plate is equipped with the fixed ring for fixed pay -off roll, one side of bottom plate is equipped with support column, the pressure mechanism is established in the top of support column, the pressure mechanism sets up in the circumference of pay -off roll upper, the utility model provides a wire drawing machine pay -off device with line pressing structure, through the cooperation setting of bottom plate, support column and pressure mechanism, can press the steel wire rope on the line roller in the upper, make the movement of steel wire more smooth in the pay -off process, reduce the knot of the steel wire between the occurrence, further cooperation setting abutting mechanism in the bottom, can extrude the steel wire on the line roller from below, make the steel wire more stable when paying -off.

This application discloses a side-blown furnace, including a hearth, a furnace body, and a furnace top. The hearth has a cavity; the furnace body is located at the top of the hearth and also has a cavity; the furnace top is located at the top of the furnace body; the cavity includes an upper cavity and a lower cavity that are interconnected, and the cavity includes a primary air zone and a flue gas zone that are interconnected. The upper cavity is connected to the primary air zone, and the width l1 of the primary air zone, the width l2 of the upper cavity, and the width l3 of the lower cavity satisfy: l2 > l3 and l2 > l1. Because the width of the upper cavity is greater than the width of the primary air zone, the primary air introduced into the primary air zone reduces the agitation and scouring of the upper cavity sidewalls, slows down the damage rate of the sidewalls, and extends the service life of the side-blown furnace. Simultaneously, because the width of the lower cavity is smaller than the width of the upper cavity, the flow rate of the melt is accelerated, thereby accelerating the heat exchange rate of the melt to maintain thermal balance within the cavity and prevent excessive condensation at the bottom of the cavity. This application also discloses a metallurgical system.

The utility model discloses an automatic cable winding and unwinding device which comprises a bearing frame, the top of the bearing frame is fixedly connected with an assembling support, the side wall of the assembling support is fixedly connected with an assembling motor, and the output end of the assembling motor is fixedly connected with an assembling winding roller. The tail end of the assembling winding roller penetrates through the assembling support and is rotationally connected with the inner wall of the assembling support, and the top and the bottom of the assembling support are both connected with fixing assemblies. According to the device, the fixed rotating shaft on the fixed disc is driven by the fixed motor to rotate, and then the fixed rotating shaft slides in the fixed concentric-square-shaped plate, so that the fixed pushing plate on the fixed concentric-square-shaped plate is pushed to move in the direction of the fixed L-shaped supporting plate, and the fixed arc-shaped plate is also driven to move along with the fixed pushing plate; therefore, the fixed arc-shaped plate controls the cable on the winding and unwinding assembly winding roller to be disengaged and loosened, the tightness of the cable is controlled, knotting of the cable is reduced, and the using effect is improved.

The utility model discloses a length adjustable's silk guide ware for textile production, including support mechanism and silk guide mechanism, the support mechanism is by fixed carrier plate, and the board of lifting and electric push rod are composed, the board of lifting, and the number of electric push rod all are equipped with two, two the board of lifting and two electric push rod are fixedly connected respectively in fixed carrier plate both ends, and two electric push rod are set up respectively in two the board of lifting top. The utility model discloses through the telescopic drive of electric push rod, can conveniently adjust the interval length between silk guide mechanism and textile lathe, and this function makes silk guide ware can adapt to different model's textile lathe and production line layout, has improved the versatility and flexibility of equipment, in actual production, according to the tension and form requirement of fibre, adjusts interval length in time, can optimize the trend of fibre, reduces the knot or wear phenomenon to improve product quality and production efficiency.

This utility model relates to the technical field of fancy composite network yarn preparation equipment. A device for preparing high-cohesion, high-weaveability fancy composite network yarn includes a base plate, a winding mechanism on the top left side of the base plate, and a guide mechanism on the top right side of the base plate. An auxiliary mechanism is provided at the bottom of the base plate. The winding mechanism includes a connecting plate, a motor mounted on the top of the connecting plate, a third gear fixedly connected to the output end of the motor, a third connecting rod fixedly connected to the top of the third gear, and a support rod fixedly connected to the top of the third connecting rod. Through holes are provided at the top and bottom ends of both sides of the support rod, and telescopic rods are installed in each of the four through holes. A support plate is fixedly connected to the telescopic end of the telescopic rod, and a spring is provided on the outside of the telescopic rod. This utility model, through the telescopic rods and springs in the winding mechanism, enables the device to adapt to rolls of different sizes, improving the production efficiency of fancy composite network yarn.
