Melt spinning dye automatic doser

Abstract

The invention provides a melt spinning dye automatic doser, belonging to the technical field of auxiliary equipment of a melt spinning system. The automatic doser comprises a rack, a feed box rotary table, a rotary table driving mechanism, a weigh rotary disk, a set of charging buckets, and a feed box automatic shift mechanism; wherein a disc-shaped platform is fixed at the top of the rack, a rotary table cavity is formed in the centre of the platform, a support baseplate is fixed on the rack, a rotary table bearing bracket bearing frame is fixed at the edge position of the support baseplate, a rotary table inner bearing bracket is fixed on the rotary table bearing bracket bearing frame; a weighing rotary disk abdicating cavity is formed in the center of the feed box rotary table, a rotary table bearing is arranged between the rotary table inner bearing bracket and a rotary table outer bearing bracket; the rotary table driving mechanism is connected with the rotary table outer bearing bracket; a weighing device is arranged in the weighing rotary disk cavity, and a weighing rotary disk driving mechanism is connected with a weighing rotary disk; a dye spiral output mechanism is arranged at the lower part of the set of charging buckets, and an actuating unit is arranged on the output mechanism; the feed box automatic shift mechanism is arranged on the disc-shaped platform. The occupied area is small; the stability and reliability of operation are guaranteed; the batching and weighing efficiencies are improved; the whole structure is compact and simple, and the safety is good.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for a melt spinning system, and in particular relates to an automatic batching machine for melt spinning dyes. Background technique [0002] The aforementioned melt spinning is the abbreviation of "melt spinning", which is a kind of chemical fiber that heats and melts the polymer, extrudes through the spinneret holes on the spinneret (also called spraying), and cools and solidifies in the air to form fibers. spinning method. The aforementioned melt-spinning dyes refer to masterbatches added to spinning raw materials such as polyester chips, polyamide chips, polypropylene particles, etc., powdered chemical dyes such as disperse blue and disperse yellow in disperse dye systems Etc., so that the spun chemical fiber filaments have the desired color, different colors of chemical fiber filaments can be obtained by dyeing different colors, and chemical fiber filaments of the desired color ca...

Problems solved by technology

[0006] A typical "powder dye automatic batching equipment" as disclosed in CN1031486A, although the patent application scheme can make up for the aforementioned shortcomings of manual weighing to a certain extent and can embody the technology described in paragraphs 3 to 7 on page 6 of the specification effect, but there are the following disadvantages: first, since multiple material tanks (patented material boxes) are arranged at intervals in the length direction of the base frame, they are bulky, which is not conducive to saving space in the spinning workplace; second, due to the dye The screw output mechanism (the patent is called the spiral discharge plate) is installed in the lower part of the material tank (the patent is called the material box), and the material tank and the dye screw output mechanism are supported on the base frame, and the base frame is supported on the floor. The power mechanism driving the dye screw output mechanism is installed on the mobile platform and driven by another power, so although one power mechanism can deal with the dye screw output mechanism at the bottom of each material tank, it needs to be used whenever the dye screw output mechanism is discharged. The power mechanism establishes a connection relationship with the dye screw output mechanism, and the connection relationship needs to be released after the discharge is completed (the patent is called coupling connection or decoupling connection), so the stability and reliability of the action are often difficult to guarantee; Third, due to the lack of The material box switching and extraction manipulator that switches between the empty material box (patented weighing box) and the weighed material box, so the continuity of the weighing action is affected to a certain extent, that is, it is difficult to guarantee the efficiency of ingredient weighing Its 4th, because overall structure is loose, lose compactness and drive the above-mentioned power mechanism of dye screw output mechanism action and the power device that drives the platform movement of carrying power mechanism all to be set with bare state, thereby on the one hand for manufacture, install, use And the maintenance brings inconvenience, on the other hand, it loses security
