The invention relates to the technical field of spinning devices, and provides a polyester cotton yarn spinning automatic tension adjusting system which comprises a machine base, mounting bases are evenly fixed to the edge of one side of the top end of the machine base, and guide wheels are evenly and rotationally connected to the outer wall of the other side of the top end of the machine base. The adjusting structure is arranged, the machine base is vertically installed on the outer wall of the spinning machine through the installation base, polyester cotton yarn penetrates through one side of the guide wheels and one side of the tensioning wheel, the tensioning wheel can conduct tensioning adjustment on the polyester cotton yarn between the guide wheels, the balancing weight is hung below a hanging ring through a hook, and under the influence of gravity, the balancing weight is hung on the upper portion of the hanging ring. According to the automatic tension adjusting system for polyester-cotton yarn spinning, the balancing weight can apply constant tension to polyester-cotton yarn through the tensioning wheel, the phenomenon that the polyester-cotton yarn is broken due to tension change in the conveying process is avoided, the device has the constant tension, meanwhile, the tension adjusting function is convenient, and therefore the working efficiency of the automatic tension adjusting system for polyester-cotton yarn spinning in the using process is improved.

The utility model discloses a fine denier fiber spinning device which comprises a material conveying pipe, one end of the material conveying pipe is communicated with a metering pump, one side of the metering pump is provided with a first servo motor, the output end of the first servo motor is in transmission connection with the metering pump, the output end of the metering pump is communicated with a spinning box, and the spinning box is provided with a spinning cavity. A spinneret plate is arranged at the bottom of the spinning box, an outer cover box is arranged at the bottom of the spinning box, a side blowing box is connected to the interior of the outer cover box in a matched mode, air outlets are formed in the front portion and the rear portion of the inner wall of the side blowing box at equal intervals, and the two sides of the side blowing box communicate with air supply pipes. The utility model relates to the technical field of spinning equipment, and solves the problems that in the prior art, a side blowing box of the spinning equipment is fixed below a spinneret plate, the distance between the spinneret plate and the side blowing box cannot be adjusted, and cooling of tows ejected by the spinneret plate is not facilitated; and the physical properties of the tows cooled in different temperature environments are different.

This invention relates to a method and corresponding apparatus for initiating melt spinning, stretching, and winding processes, wherein yarn (2) extruded from a spinneret nozzle (3) is applied to a first oiling device (4.1), a stretching device (5), a second oiling device (4.2), and a winding machine (6), wherein, either during application, oil is supplied without the aid of the first oiling device (4.1) and / or the second oiling device (4.2), and / or during application, oil is supplied with the aid of the first oiling device (4.1) and / or the second oiling device (4.2) at a predetermined initial flow rate (Q). tA The oil is supplied with an initial flow rate (Q). tA ) greater than the production flow rate (Q) tP ), of which production flow rate (Q) tP This prepares for subsequent yarn (2) production, wherein, after application, the initial flow rate (Q) of the oil in each oiling device (4.1, 4.2) is [not specified]. tA ) is set as the production flow rate (Q) tP ).

The utility model discloses an anti-collision stone sawing chain which comprises a plurality of welding base bodies and a plurality of transmission pieces, the welding base bodies and the transmission pieces are distributed alternately, each welding base body is provided with a cutting knife, each welding base body is provided with an upper clamping groove used for clamping the cutting knife, and correspondingly, each welding base body is provided with a lower clamping groove used for clamping the cutting knife. Upper clamping grooves are formed in the welding base body, lower clamping grooves are formed in the cutting knives, the upper clamping grooves and the lower clamping grooves are matched with each other to clamp the cutting knives on the welding base body, the welding base body and the transmission piece are connected together through a connecting assembly, and an anti-collision piece is arranged between every two adjacent cutting knives. According to the cutting device, the cutting knife can be better prevented from being broken, the situation that anti-collision pieces are concentrated on the welding base body is avoided, the welding base body is better prevented from being damaged, the damage condition is better avoided, the service life of equipment is better prolonged, and the use requirement is better met.
