Description

Technical Field

[0001] This utility model relates to the field of polyurethane fiber processing technology, specifically to a processing equipment for high-temperature resistant polyurethane elastic fibers. Background Technology

[0002] Polyurethane elastic fiber is a multi-block copolymer consisting of alternating soft and hard segments. The soft segments in polyurethane elastic fiber are composed of polyester polyols or polyether polyols, while the hard segments are generated by the reaction of isocyanate with small molecule chain extenders.

[0003] A search revealed that patent application CN112725928B discloses a method for preparing high-temperature resistant polyurethane elastic fibers. The method involves adding toughening agents, synergistic strengthening agents, and heat-resistant agents to a solution, stirring and fusing them thoroughly, and then allowing it to stand at a certain temperature and for a certain time to fully mature. At 40°C, a high-temperature resistant polyurethane elastic fiber spinning solution with a viscosity of 500~1100 Pa·s is obtained. The spinning solution has a certain degree of crystallinity, ranging from 1% to 2%, which can improve the elasticity and high-temperature resistance of the polyurethane fibers.

[0004] However, when adding toughening agents, strength enhancers and heat resistant agents to the solution, the solution needs to be controlled at around 40 degrees Celsius. Temperature control is inconvenient and affects the curing effect of the solution, resulting in poor performance of the polyurethane elastic fiber raw solution. At the same time, the pipe wall effect occurs during mixing, resulting in low mixing uniformity and low high-temperature resistance of the produced polyurethane fibers.

[0005] Therefore, we propose a processing equipment for high-temperature resistant polyurethane elastic fibers. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a processing device for high-temperature resistant polyurethane elastic fibers, which solves the problems of inconvenient temperature control and uneven mixing in existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a processing equipment for high-temperature resistant polyurethane elastic fibers, including a base, on which a mixing cylinder of suitable specifications is assembled.

[0008] A water bath of the same specifications is fixedly installed on the top surface of the base. A ring-shaped heating block of the same specifications is assembled between the outer and inner walls of the water bath. A control processor connected to the heating block is assembled on the outer wall of the water bath. Four sets of telescopic cylinders with opposite positions are fixedly installed at the bottom of the water bath. A fixing frame is fixedly installed on the outer wall of the mixing cylinder. The bottom surface of the fixing frame is connected to the top of the telescopic cylinder.

[0009] The mixing cylinder is fitted with a cylinder cover on its top surface. A drive motor is fixedly installed on the top surface of the cylinder cover. A rotating rod is fitted onto the output end of the drive motor on the bottom surface of the cylinder cover. A stirring rod with uniformly distributed and matching specifications is fixedly installed on the outer wall of the rotating rod. A secondary rod with uniformly distributed specifications is fitted onto the bottom surface of the cylinder cover via a bearing. A gear A with matching specifications is fixedly installed on the outer wall of the rotating rod. A gear B that meshes with gear A is fixedly installed on the outer wall of the secondary rod. The diameter of gear A is larger than the diameter of gear B. A stirring block with uniformly distributed specifications is fixedly installed on the outer wall of the secondary rod. The distance between the stirring block and the inner wall of the mixing cylinder is 5 mm.

[0010] Preferably, three sets of feed pipes with opposite positions are fixedly installed on the outer wall of the mixing cylinder, and the output end of the feed pipe is located below gear A, which facilitates the injection of raw materials into the mixing cylinder.

[0011] Preferably, a discharge pipe is fixedly installed on the bottom surface of the mixing cylinder, and a mechanical valve is fitted on the outer wall of the discharge pipe to facilitate the discharge of polyurethane elastic fiber raw liquid.

[0012] Preferably, the outer wall of the water bath is equipped with a drain outlet in a corresponding position, which facilitates the drainage of water from the water bath.

[0013] Preferably, the inner wall of the water bath is equipped with a thermally conductive coating, which can improve the efficiency and effectiveness of the heating block in heating the water.

[0014] Preferably, vertically placed reinforcing rods are fixedly installed between the stirring rods. This can improve the strength of the stirring rods and prevent breakage. The vertical rods can also improve the uniformity of stirring.

[0015] This equipment for processing high-temperature resistant polyurethane elastic fibers uses a water bath, a heating block, and a telescopic cylinder. The telescopic cylinder moves the mixing cylinder downwards and immerses it in water. The heating block heats and keeps the water in the water bath warm. The water bath heating is effective, provides uniform heating, and improves the convenience of temperature control.

[0016] Simultaneously, through the configuration of the drive motor, stirring rod, and stirring block, the drive motor drives the rotating rod and stirring rod to rotate. Gear A on the rotating rod meshes with gear B to rotate, thereby driving the secondary rod to rotate rapidly. The stirring block on the secondary rod stirs and mixes the surrounding area of ​​the tube wall, reducing the tube wall effect and improving the uniformity and effect of mixing.
