Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of spandex production equipment, and particularly relates to a flat push type lifting-free polymerization reaction device for spandex production. BACKGROUND

[0002] Spandex is an elastic fiber made of a high polymer compound with a linear chain segment structure and containing more than 85% of polyurethane. It has the advantages that other fibers cannot match, such as light specific gravity, high breaking strength, high elongation at break, good elastic recovery, etc. It is known as the second skin of the human body, is a material for modern clothing industry and a garment fabric, and has a wider application in various fields.

[0003] The main process for producing spandex is dry spinning, and the dry spinning yield accounts for about 80% of the total spandex yield in the world. The main process for producing spandex by dry spinning is as follows: polyether glycol and diisocyanate are reacted at a molar ratio of 1:2 under certain reaction temperature and time conditions to form a prepolymer, the prepolymer is dissolved in a solvent, then diamine is added for chain extension reaction to form a block copolymer solution, then additives are added for mixing, filtering, defoaming and other processes to produce a spinning solution with uniform performance. Then the solution is uniformly pressed into a spinneret by a metering pump, the spinning solution is extruded from the capillary holes of the spinneret plate to form a filament stream, and then enters a spinning duct. The duct is filled with hot air (or hot nitrogen gas) to rapidly volatilize the solvent in the filament stream and carry it away by the air (or nitrogen gas), and the concentration of the filament is continuously increased until it is solidified. Generally, spandex is a multifilament, which is twisted by a twisting device before solidification, and then is oiled and wound into a certain package.

[0004] US16351590 discloses a modular cargo storage system (CSS) for use on a base platform of a modular autonomous robotic device that transports an item being transported. The modular CS includes a set of foldable structural walls, interlocking alignment interfaces on at least one wall, the walls at least partially enclosing a payload area above the base platform. The interlocking alignment interfaces have a set of latches and a locking handle connected to the set of latches, the locking handle actuating the latches to interlock with the base platform.

[0005] In the existing spandex production process, the lifting unloading is time-consuming and the unloading time is not easy to control, and the replacement time is too long through the lifting of the trolley, thereby affecting the polymerization reaction time and leading to uncontrollable reaction time.

The flat-pushing type lifting-free polymerization reaction device for spandex production of the application further has a cage-shaped protection device, and the cage-shaped protection device can provide protection effect while protecting the freedom.

[0017] More preferably, the cage-shaped protection device is provided with a protection assembly.

[0018] More preferably, the protection assembly is composed of an elastic member and an arc-shaped blocking piece, the elastic member is connected with a fixed block, the fixed block is connected with the fixed cage column of the cage-shaped protection device, the other end of the elastic member is connected with an elastic member fixed block, and the elastic member fixed block is located on the arc-shaped blocking piece.

[0024] More preferably, the stroller bottom plate side is provided with a combination component, which can combine single strollers into a combination stroller, and at least two strollers can be combined. The combination component is a prior art, as long as it can be used to combine two or more strollers for the production of spandex filaments. When more than three strollers are combined, the combination component needs to be provided on both sides of the stroller bottom plate of the middle stroller.

In addition to providing protection for the reaction kettle, it also allows the reaction kettle to rotate between them. The spring provides a certain elastic space to ensure that the reset assembly can effectively play its role, and further avoid the uncontrolled tilting of the reaction kettle, which avoids the overturning of the stroller for the production of spandex filaments. The spring further allows the protection assembly to adapt to the protection of reaction kettles of different sizes. Under the action of the spring and the arc-shaped blocking piece, the upper part of the reaction kettle in the stroller has more activity, while the bottom of the reaction kettle has less activity. This makes the upper and lower parts of the reaction kettle in the stroller have different degrees of activity, which makes the mixing of the upper and lower layers of the reaction liquid in the reaction kettle form a gradient difference, which is more conducive to the production of spandex filaments.

[0026] The polymeric reaction device for spandex production of the present application can place the reaction kettle, the reaction kettle can be installed on the trolley, the trolley can be pushed horizontally, and the trolley can be moved left and right. The trolley can not only horizontally push the discharge, quickly change the trolley, shorten the replacement time, improve the continuity of polymerization, but also can provide the movement angle of three-dimensional space through the movement of the trolley moving plate, the setting of the moving plate and the setting of the reset assembly. The reaction liquid in the reaction kettle is premixed, and the reaction liquid in the reaction kettle is integrally mixed under the action of the reset assembly and the moving plate, so that the uniformity of the subsequent spinning product is ensured. The protection assembly is arranged on the fixed cage column on the both sides of the cage-shaped protection device, the protection assembly is composed of a conical spring and an arc-shaped blocking piece, the arc-shaped blocking piece is provided with a ball, the reaction kettle is provided with protection, and the upper part of the reaction kettle can also be rotated. The spring provides a certain elastic space, so that the protection assembly can adapt to the protection of reaction kettles of different sizes, the reset assembly can effectively play a role, and the reaction kettle is prevented from being uncontrollably inclined. Under the action of the spring and the arc-shaped blocking piece, the upper part of the reaction kettle in the trolley is more movable, and the lower part of the reaction kettle is less movable, so that the upper and lower parts of the reaction kettle in the trolley are different in activity, the mixing of the upper and lower layers of the reaction liquid in the reaction kettle forms a gradient difference, and the production of spandex is more beneficial. The reaction kettle installed on the trolley solves the technical problems that the reaction kettle in the existing production line is time-consuming and difficult to control in unloading time through lifting. The reaction kettle is loaded on the trolley, the reaction kettle is conveniently installed on the trolley, or unloaded from the trolley, and even after the reaction is completed, the reaction kettle can be stably disassembled. Therefore, the polymeric reaction device for spandex production of the present application can adjust the angle, has high freedom, has swing flexibility, is good in protection, is easy to disassemble, is convenient to install, has three-dimensional activity effect, and the like.
