Quadrant valve for polyester chip packer

Abstract

The invention discloses a quadrant valve for a polyester chip packer, which comprises a fine discharging quadrant valve plate and a discharging closing quadrant valve plate, wherein the bottom of the fine discharging quadrant valve plate is arc-shaped, a fine discharging hole is arranged in the arc-shaped bottom, and the fine discharging quadrant valve plate is arranged on a pipeline through a fine discharging drive shaft, the bottom of the discharging closing quadrant valve plate is arc-shaped, and the discharging closing quadrant valve plate is arranged on the pipeline through a discharging closing shaft. According to the invention, through adoption of a control device, the fine discharging quadrant valve plate and the discharging closing quadrant valve plate can be controlled so as to regulate the blanking speed, so that the blanking speed is reduced when bagging is almost ended, the loading precision is well controlled, the loading error is reduced, and the loading packaging can be completed within an error range without manual regulation. The polyester chip packer provided by the invention has the advantages of reducing manual operation, lowering hand labor cost, reducing labor intensity of workers by adopting an automatic regulating mode, and increasing production efficiency.

Description

technical field [0001] The invention relates to the field of polyester synthetic fiber production, in particular to a polyester chip packer. Background technique [0002] In the existing production of polyester synthetic fibers, polyester chips need to be metered and packaged. At present, the commonly used balers are manual balers, and all manual (4 manual) operations are used in the packaging process, such as figure 1 As shown, the operator puts the empty bag on the electronic scale, hangs four hanging bag openings, turns on the compressed air switch, and blows compressed air into the packaging bag, mainly to open the dead corner of the packaging bag and fill the packaging bag smoothly for slices. Then open the manual gate valve, the slices are poured in from the hopper, according to the display screen of the electronic scale, close the gate valve after reaching the predetermined weight, according to the predetermined weight, if there is too much, manually take out a little...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the disadvantages of the existing valves for manual balers are: the accuracy of weighing is affected by the time of opening and closing the valve, and because the flow rate of the valve is large, the proficiency of the operator has a great influence on the packing speed. In order to meet the The allowable deviation of weighing is ±1 kg, often need to take out or add polyester chips many times, the production efficiency is extremely low
