Description
Technical field
The utility model relates to a kind of spinning-drawing machine screw extruder, especially thread groove screw extruder barrel.
Background technology
Screw extruder is a kind of key equipment in spinning equipment, the melt Conveying performance of screw machine extruder directly determines production efficiency and extrudes feature, the screw extruder of current application is generally smooth cylindrical shell, be difficult to efficient driving and the steady extruding of the material realizing low-friction coefficient, production capacity is low, and upbuild voltage capacity is poor.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, thread groove screw extruder barrel is provided, adopt the mode of establishing thread groove at screw extruder barrel inwall, when screw rod rotates, conveying solid substance is under the propelling angle of groove and the pressure surface acting in conjunction of screw rod, push ahead along spiral angle, pressure increase, greatly increase transfer efficiency.
For achieving the above object, the technical solution of the utility model is: comprise flange one, flange two, charging shelves, machine drum body, thread groove, discharge opening, flange three, left end is flange one, charging shelves are established in the middle of described flange one and flange two, described charging shelves establish charging aperture, described charging aperture plane is provided with fastening screw, and with discharge opening intercommunication, discharge opening inwall of telling is provided with thread groove, described thread groove spreads all over the length of whole machine drum body, described cylindrical shell left end connects with flange two, and right-hand member is connected with flange three.
Further setting, pitch and the supporting extruder screw of described thread groove match.
Further setting, the gash depth of described thread groove is less than the particle diameter of transmission.
Further setting, the groove width of described thread groove is greater than the particle diameter of transmission.
The beneficial effects of the utility model are: adopt the mode of establishing thread groove at screw extruder barrel inwall, when screw rod rotates, conveying solid substance is under the propelling angle of groove and the pressure surface acting in conjunction of screw rod, push ahead along spiral angle, build pressure performance strong, barometric gradient is mild, increases transfer efficiency; The degree of depth of thread groove is less than the particle diameter of transmission, be conducive to can be larger build pressure and supercharging, be convenient to compression and the homogenizing of melt; The width of thread groove is greater than the particle diameter of transmission, is conducive to improving the compression of melt granules and the production capacity of homogenizing and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model.
In figure: flange 1, flange 22, charging shelves 3, charging aperture 31, fastening screw 32, machine drum body 4, thread groove 5, discharge opening 6, flange 37.
Detailed description of the invention
Below by embodiment and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
As shown in Fig. 1 ~ Fig. 2, thread groove screw extruder barrel, comprise flange 1, flange 22, charging shelves 3, machine drum body 4, thread groove 5, discharge opening 6, flange 37, left end is flange 1, charging shelves 3 are established in the middle of described flange 1 and flange 22, described charging shelves 3 establish charging aperture 31, described charging aperture 31 plane is provided with fastening screw 32, and with discharge opening 6 intercommunication, institute's discharge opening of telling 6 inwall is provided with thread groove 5, described thread groove 5 spreads all over the length of whole machine drum body 4, and described cylindrical shell 4 left end connects with flange 22, and right-hand member is connected with flange 37.The utility model adopts the mode of establishing thread groove 5 at screw extruder barrel body 4 inwall, when screw rod rotates, conveying solid substance is under the propelling angle of spiral grooves 5 and the pressure surface acting in conjunction of screw rod, push ahead along spiral angle, build pressure performance strong, barometric gradient is mild, increases transfer efficiency.
Dark and the supporting extruder screw in the classification of described thread groove 5, pitch, footpath matches, can well by the thread groove 5 of solid material along machine drum body 4 that enter and the direction forward transmission at screw spiral angle.
The gash depth of described thread groove 5 is less than the particle diameter of transmission, be conducive to can be larger build pressure and supercharging, be convenient to compression and the homogenizing of melt.
The groove width of described thread groove 5 is greater than the particle diameter of transmission, is conducive to improving the compression of melt granules and the production capacity of homogenizing and efficiency.
More than show and describe general principle of the present utility model and principal character, and advantage of the present utility model.The technical staff of the industry also understands; the utility model is not by the restriction of above-mentioned case study on implementation; what describe in above-mentioned case study on implementation and description just illustrates principle of the present utility model; do not departing under the utility model design category prerequisite; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appended claims and equivalent thereof.
