Description

Technical Field

[0001] The utility model belongs to the technical field related to spinning, in particular to a feeding device for a continuous spinning injection machine. Background Art

[0002] The continuous spinning process is a method that combines the spinning and post-processing (including washing, drying, barreling, etc.) processes together to complete them continuously. This process is characterized by short production cycle, low cost and high product quality. Usually, the relevant slurries need to be mixed during spinning, and then the slurries are processed by spinning to form spinning. However, when feeding, the relevant feeding equipment still has the following disadvantages:

[0003] In the continuous spinning production process, the injection machine is one of the key equipment. The traditional injection machine usually adopts a one-to-one feeding method, that is, one injection machine only feeds one spinning equipment. This method has the problems of low equipment utilization and high cost.

[0004] Secondly, when feeding, mixing is usually required. However, mixing necessarily involves stirring, and a large number of bubbles may be generated during this process, which can easily affect subsequent operations such as spinning.

[0005] Finally, since continuous spinning is generally a non-stop operation, the raw materials supplied will eventually be consumed. During this replenishment interval, the normal injection use of continuous spinning cannot be guaranteed. Utility Model Content

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a feeding device for a continuous spinning injection machine, comprising a mounting frame, a booster pump, a dynamic mixer, a transfer box, a main pipe and a static mixer.

[0013] Furthermore, the dynamic mixer is fixed in the middle plate and the top plate, and the upper part of the dynamic mixer extends out of the top plate.

[0014] Furthermore, the chamber formed on one side of the partition close to the filter screen 1 and below the filter screen 1 is set as a processing chamber, and the chamber formed above the filter screen 1 and the other side of the partition is a transfer chamber.

[0015] Furthermore, a discharge pipe is fixed at the bottom of the dynamic mixer, and one end of the discharge pipe away from the dynamic mixer is fixedly connected with the processing chamber in the transfer box, the main pipe is connected with the transfer chamber, and a discharge valve is fixed on the discharge pipe.

[0016] Furthermore, a control valve 1 is fixed on the branch pipe, a connecting pipe is fixed on the upper end of the static mixer, and a control valve 2 is fixed on the connecting pipe.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problems of low equipment utilization and high cost in a one-to-one feeding method by arranging a static mixer and a dynamic mixer; the required raw materials are extracted by a feeding pump 1 and a feeding pump 2, enter the booster pump for transfer, and then enter the dynamic mixer for dynamic mixing treatment, and then enter the transfer box for transfer, enter the main pipe and then be diverted through the branch pipe to enter the two static mixers. The two static mixers can transport to two spinning machines to supply the two static mixers.

Even when the subsequent raw materials need to be supplemented after the feeding is completed, the remaining materials in the transfer box can still be used for feeding for a certain period of time. After the booster pump is pressurized, a certain pressure can be guaranteed in the transfer box, so that uninterrupted feeding of continuous spinning can be realized.
