Description

Technical Field

[0001] The invention relates to the technical field of spinning machines, which are key equipment in a fiber manufacturing process, and in particular to a large-capacity wet horizontal spinning machine. Background Art

[0002] To spin a polymer into fiber, it must be melted into a melt or dissolved into a viscous solution, and then condensed or solidified into a fiber through a spinneret. If a polymer is melted into a melt, the necessary condition is that its melting point must be lower than the decomposition point. If the melting point is higher than the decomposition point, the polymer will not melt and the polymer material will begin to decompose. Therefore, the melt method cannot be used to spin fibers. Synthetic or natural polymers such as polyvinyl alcohol resin (PVA resin), sodium alginate, cellulose, milk, and soybeans have a thermal decomposition temperature lower than the thermal melting temperature, so only solution spinning can be used. Polyvinyl alcohol, seaweed, cellulose, milk, soybeans and other fibers are all made using solution wet spinning technology.

[0003] Domestic and foreign wet spinning machines use two types: vertical spinning machines and horizontal spinning machines. Due to the different structures of the two, the spinning process is slightly different. Features: Horizontal spinning machines are easy to operate and have large output (of course, vertical spinning machines can also achieve large production capacity by using multiple spindles), which is suitable for short fiber production; vertical spinning machines are difficult to operate, and the fiber fineness CV value is small, which is suitable for filament production.

[0004] At present, the production of polyvinyl alcohol (PVA), seaweed, cellulose, milk, soybean and other fibers at home and abroad all adopt the solution wet spinning process, and the short fiber spinning equipment all adopts wet horizontal spinning machine. Each spinning machine has 3 spindles, and the general equipment is arranged in a "one" shape with three units in the front, middle and back of the left and right hands; the distance between the front, middle and back spinning machines and the nascent fibers in the bath is as much as 7 to 14 meters, and each spinning machine outlet must be equipped with a separate drafting roller to ensure that the difference between the front, middle and back of the nascent fibers is not large. This spinning machine and arrangement have the following problems: the equipment arrangement occupies a large plant area and the production capacity is low. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a large-capacity wet horizontal spinning machine.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A large-capacity wet horizontal spinning machine equipment comprises a plurality of multi-spindle spinning machines arranged laterally, each of the multi-spindle spinning machines is provided with a plurality of spinning spindles; a plurality of separate baths are provided in the multi-spindle spinning machines, one end of each separate bath is provided with a spinneret, the stock solution sprayed out by the spinneret is formed into a fiber bundle in the separate bath, a horizontal steering guide roller and an independent steering guide wheel are provided at the end of the multi-spindle spinning machine away from the spinneret, and the independent steering guide wheel is located at the bottom of the horizontal steering guide roller; a wire guide is provided at the end of the separate bath away from the spinneret; a bundle transition bath corresponding to the plurality of multi-spindle spinning machines is provided at the bottom of the independent steering guide wheel, a shaping guide roller and a plurality of wire pressing guide rods are provided in the bundle transition bath, a three-roller drawing machine is provided at one end of the bundle transition bath, and the fiber bundle in the bundle transition bath enters the first guide roller of the three-roller drawing machine through the wire pressing guide rod and the shaping guide roller.

The horizontal steering guide roller is made of stainless steel, and the rotation speed of the horizontal steering guide roller is 8-20 m / min.

[0011] Preferably, the bottom of the independent steering guide wheel is immersed in the bath liquid in the tow transition bath. The independent steering guide wheel is a driving wheel, which is used to redirect the fiber tow that is turned vertically downward by the horizontal steering guide roller to run horizontally, thereby ensuring that the fiber tow runs horizontally in the tow transition bath. The independent steering guide wheel is made of stainless steel, and the rotation speed of the independent steering guide wheel is 8~20m / min.

[0012] Preferably, the bath liquid in the tow transition bath is immersed to one-half of the independent steering guide wheel.

[0020] 4. Improve fiber quality and shaping effect: Equipped with fine guide wires, guide rollers, steering guide wheels and other components, it effectively controls the traction and shaping effect of the tow, ensures the consistency and quality stability of the fiber tow, and thus improves the performance of the fiber.
