Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of polylactic acid fiber production, and specifically relates to a crimping machine used for polylactic acid fiber production. Background Art
[0002] In the production process of PLON fiber (modified polylactic acid fiber), the crimping machine is an indispensable and important equipment. The main function of the crimping machine is to make the polylactic acid fiber obtain the desired curling effect through a specific mechanical structure and movement mode, thereby improving the elasticity, feel and processing performance of the fiber. However, the traditional polylactic acid fiber crimping machine has some limitations in design and function, which restricts its application in actual production. Traditional polylactic acid fiber crimping machines usually adopt a fixed crimping knife design, and the spacing between the crimping knives is fixed and cannot be adjusted according to the production requirements of different types of polylactic acid fibers. This design results in the crimping machine being unable to obtain the best crimping effect when producing different fibers, affecting the quality and performance of the fiber. To solve the above problems, we propose a crimping machine for polylactic acid fiber production. Utility Model Content
[0003] The utility model aims to provide a crimping machine for producing polylactic acid fibers.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A curling machine for the production of polylactic acid fibers, characterized in that: it comprises two curling rollers symmetrically arranged up and down and a first driving device connected to the curling rollers and driving the curling rollers to rotate, and there is a gap between the two curling rollers; two curling knives are symmetrically arranged up and down on the feeding side of the curling roller, one of the curling knives is movably arranged up and down, and a second driving device for driving the curling knife to move up and down is arranged on one side of the curling knife; the polylactic acid fibers pass through between the two curling knives and the two curling rollers respectively, and contact the curling knives and the curling rollers.
[0006] Preferably, it further comprises a frame, the two curling rollers are arranged on the frame, one of the curling knives is arranged on the frame, and the second driving device is arranged on the frame.
[0007] Preferably, the first driving device is a pulley transmission device.
[0008] Preferably, the second driving device is a cylinder, and the output end of the cylinder is connected to one of the curling knives.
[0009] Preferably, the gap between the two crimping rollers is 0.1 to 0.5 mm.
[0010] Preferably, it further comprises heating end covers respectively arranged at the ends of both sides of the curling roller, and the heating end covers are threadedly connected to the ends of the curling roller.
[0011] The beneficial effect of the utility model is that the curling knife is upgraded from the previous fixed type to a lifting movable type to modify the spacing between the curling knives to meet the production needs of different types of polylactic acid fibers, so that the curling elasticity of the polylactic acid fiber is adjustable. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a structural schematic diagram of a crimping machine for polylactic acid fiber production according to the utility model;
[0013] Among them: a curling roller 10, a pulley transmission device 12, a curling knife 14, a cylinder 16, a frame 18, and a heating end cover 20. DETAILED DESCRIPTION
[0014] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0015] like Figure 1 As shown, the utility model is a curling machine for the production of polylactic acid fibers, comprising two curling rollers 10 symmetrically arranged up and down and a first driving device connected to the curling rollers 10 and driving the curling rollers 10 to rotate, with a gap between the two curling rollers 10; two curling knives 14 are symmetrically arranged up and down on the feeding side of the curling roller 10, one of the curling knives 14 is movably arranged up and down, and a second driving device for driving the curling knife 14 to move up and down is arranged on one side of the curling knife 14; the polylactic acid fibers pass through the two curling knives 14 and the two curling rollers 10 respectively, and contact the curling knives 14 and the curling rollers 10.
[0016] The machine frame 18 is also included. Two curling rollers 10 are arranged on the machine frame 18 , one curling knife 14 is arranged on the machine frame 18 , and a second driving device is arranged on the machine frame 18 .
[0017] The first driving device is a pulley transmission device 12 .
[0018] The second driving device is a cylinder 16 , and an output end of the cylinder 16 is connected to one of the curling knives 14 .
[0019] The gap between the two crimping rollers 10 is 0.1 to 0.5 mm.
[0020] The heating end caps 20 are respectively arranged at the ends of both sides of the crimping roller 10, and the heating end caps 20 are threadedly connected to the ends of the crimping roller 10. The heating end caps 20 heat the crimping roller 10 so that the crimping roller 10 maintains a constant temperature required for the modified polylactic acid fiber to change its elasticity.
[0021] During production, the second drive device drives the curling knife 14 to move up and down, changing the spacing between the curling knives 14 to adjust the fiber curling elasticity, thereby making the elasticity more stable during the production of PLON and improving the product production quality. It is also suitable for the production of coarse denier yarns.
