Problems solved by technology

[0004] Some factories have also begun to study making the silk cake bigger to improve work efficiency. However, simply increasing the outer diameter of the centrifugal tank and prolonging the pure spinning time to increase the weight of the silk cake will lead to an excessive increase in the thickness of the silk cake, not only the inside and outside of the raw silk The physical properties of the layer will decrease, which will also lead to the deterioration of the subsequent refining effect and drying effect, and affect the strength, elongation, fineness and dyeing performance of the fiber

Embodiment 1

[0039] see figure 1 As shown, the semi-continuous spinning machine of this embodiment needs to produce a kind of big silk cake, and the dry weight of described silk cake is 0.9kg~1.5kg, and described silk cake is hollow cylinder structure, and the outer diameter of silk cake is The ratio to the thickness of the silk cake is (5-9):1.

[0040] In the above scheme, the ratio of the outer diameter of the silk cake to the thickness of the silk cake is (5-9): 1, thus ensuring the refining effect and drying effect of the subsequent processing of the silk cake while increasing the weight of the silk cake. It will not reduce the physical properties of the inner and outer layers of the original silk by simply increasing the thickness of the silk cake like the existing ones, and will also lead to poorer refining and drying effects in the follow-up, affecting the strength, elongation, fineness and dyeing performance of the fibers.

[0041] Preferably, the ratio of the outer diameter of t...

Embodiment 2

[0051] The second embodiment provides a semi-continuous spinning machine for producing the silk cake in the first implementation, including a winding device, the winding device includes a centrifuge tank, and the centrifuge tank has a cylindrical chamber, and the inner diameter of the chamber is the same as The height ratio is (0.7~1.2):1. Preferably, the ratio of the height of the chamber to the height of the silk cake is (1.0-1.5):1. Further preferably, the height of the chamber is greater than the height of the silk cake by 3-5 cm.

[0052] In the above solution, in order to produce the large silk cake, the present invention performs adaptive design on the structural size of the centrifuge tank, so as to realize the production of the silk cake.

[0053] Preferably, the inner diameter of the cylindrical chamber is 165-325 mm, and the height is 165-200 mm; more preferably, the inner diameter of the cylindrical chamber is 204-206 mm, and the height is 190-199 mm; Most prefer...

Embodiment 3

[0065] The present embodiment further provides the structure of a semi-continuous spinning machine. The semi-continuous spinning machine includes a centrifugal tank, a lifting rod, a funnel bracket installed on the lifting rod and a cam that drives the lifting rod to move up and down. The inside of the centrifugal tank has a chamber. The ratio of the stroke of the cam to the height of the chamber of the centrifuge tank is (130~170):(165~200). Cam structure see image 3 and Figure 4 .

[0066] In the above scheme, the lifting stroke of the original cam is increased, and part of the structural modification of the whole machine is carried out to increase the height of the manufactured silk cake, expand the adjustment range of the winding angle of the silk cake, and ensure the high-speed spinning speed. The movement is stable, and large silk cakes can be produced, saving a lot of labor.

[0067] Preferably, in the present invention, the stroke of the cam is 130-170 mm. More p...

Abstract

The invention discloses a semi-continuous spinning machine and a spinning cake production process thereof. The semi-continuous spinning machine comprises a centrifugal spinning pot, a lifting rod, a hopper support disposed on the lifting rod, and a cam for driving the lifting rod to move up and down. The ratio of a stroke of the cam to a height of a chamber in the centrifugal spinning pot is (130-170):(165-200). In the semi-continuous spinning machine, an original lifting stroke of the cam is increased, part of the structure of the whole machine is refitted, the height of manufactured spinningcakes is increased, the adjustment range of winding angles of the spinning cakes is enlarged, the stable lifting movement at a high spinning speed is ensured, the large spinning cakes can be produced, and lots of labor is saved.

Description

technical field [0001] The invention relates to the field of semi-continuous spun viscose filaments, in particular to a semi-continuous spinning machine and a silk cake production process thereof. Background technique [0002] Most factories now use semi-continuous spinning machines to produce viscose filament cakes, and the weight of the produced silk cakes is generally 0.4-0.6kg / piece. However, the doffing process is operated by humans. The silk sliver needs to be cut off, and waste silk will be produced. If the silk cake is too small, the number of doffing times and the amount of waste silk will be increased. [0003] At the same time, the silk cake needs to be wound into a larger bobbin through the winding machine, which is also a 2kg silk cake. If 4 silk cakes are wound around a silk bobbin instead of 3 cakes per bobbin, the process of making the silk cake into a bobbin Among them, the operator reduces the number of silk cakes and joints to be handled, and improves wor...
