Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, in particular to an acrylic fiber texturing machine. Background Art

[0002] The texturing machine is a device that texturizes and deforms pre-oriented yarn (POY). Its structure includes an upper hot box (deformation hot box), a cold rail, a false twister, and a lower hot box (setting hot box). The silk thread passes through the above structure in sequence to transform the POY into a drawn textured yarn (DTY) with relatively stable physical properties that can be directly used for weaving. In the existing texturizing machine, the upper hot box and the cold rail are located at the upper part of the machine, and the false twister is located below the cold rail. After being heated by the upper hot box, the tensile stress of the silk thread is significantly reduced, and the silk thread is stretched. After the heated silk thread is cooled by the cold rail, it is transported to the false twister for false twisting, and then transported to the lower hot box for setting. Using the existing texturizing machine equipment to directly produce acrylic fiber will cause the following problems:

[0003] 1. The glass transition temperature of acrylic fiber is usually around 90℃, which is higher than that of polyester. The temperature of acrylic fiber drops too low after passing through the original cooling track. When it enters the false twister, the temperature is too low, and the false twist effect is poor;

[0004] 2. The acrylic fiber raw yarn paper tube is longer than the polyester raw yarn paper tube. When the acrylic raw yarn is pulled out to the raw yarn rack porcelain ring, it is easy to rub against the edge of the paper tube and cause the yarn to break;

[0005] 3. The strength of acrylic fiber is lower than that of polyester fiber, and the fiber is prone to breakage if the speed is too fast during the elastic deformation process. Utility Model Content

[0006] In view of this, the utility model aims to provide an acrylic fiber texturing machine, which makes the silk thread run smoothly and improves the false twist effect of acrylic fiber raw silk.

[0007] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0008] An acrylic fiber texturing machine comprises a raw yarn frame assembly, a sub-frame, a main frame, and a winding mechanism, wherein the main frame is arranged in the middle of the sub-frame, and the raw yarn frame assembly is arranged on the side of the sub-frame;

[0009] The winding mechanism is arranged on both sides of the inner part of the auxiliary frame, and a wire assembly is arranged between the winding mechanism and the main frame; W1 rollers are arranged on both sides of the inner part of the auxiliary frame, and the W1 rollers are arranged above the winding device, wire cutters are arranged on both sides of the outer part of the auxiliary frame, and an upper heating box is arranged between the auxiliary frame and the main frame;

[0011] The first winding assembly and the second winding assembly are evenly and equidistantly arranged on the inner side of the auxiliary frame;

[0012] The first winding assembly includes a plurality of winding components, and the number of the winding components is at least the number of the raw yarn drums of the raw yarn rack assembly.

[0013] The number of the first winding assemblies is three;

[0014] The number of the second winding assemblies is four.

[0015] The first winding component and the second winding component adopt the winding components of the texturing machine in the prior art.

[0016] Furthermore, the raw yarn rack assembly includes a raw yarn rack, a raw yarn tube, and a support tube.

[0019] A baffle is arranged on the conical upper portion of the support tube, a clamping ring is arranged on the baffle, and the distance between the clamping ring and the inner wall of the support tube corresponds to the thickness of the raw silk tube.

[0020] The raw wire rack adopts the existing technology. There is a wire tube corresponding to the support tube on the raw wire rack. The wire tube is extended to be set on one side of the wire cutter. Both sides of the top plate are provided with wire guide porcelain plates.

[0021] Furthermore, a top plate for mounting an upper heat box is provided on the top of the main frame; one end of the upper heat box is mounted on the auxiliary frame through a heat box hanging plate, and the other end is mounted on the top plate;

[0022] The end of the upper heating box close to the guide wire porcelain disk is provided with a first wire tube.

[0023] The upper heat box of the present application is tiltedly arranged between the top of the auxiliary frame and the top of the main frame. By simplifying the support frame structure, the height of the top of the main frame is reduced, thereby reducing the height of the upper heat box and shortening the length of the upper heat box.

[0024] Preferably, the vertical distance between the first wire tube of the upper heat box and the false twister is 400-500 mm.

[0025] Furthermore, the length of the upper heat box is 1300-1500 mm.

[0030] The first wire moving plate comprises a straight plate and an L-shaped plate. The straight plate is connected to the vertical end of the L-shaped plate and is mounted on the concave mounting plate. The horizontal end of the L-shaped plate is provided with a plurality of evenly distributed first wire moving devices.

[0031] Furthermore, the upper and lower ends of the lower heat box are both provided with second heat pipes, the position of the second heat pipes corresponds to the W2 roller, and the position of the second heat pipes corresponds to the position of the second wire moving assembly.

[0032] Furthermore, a bottom plate for installing the second wire moving assembly is provided at the bottom of the two lower heat boxes, and the two second wire moving assemblies are arranged on both sides of the bottom plate.

[0033] Furthermore, the second wire moving assembly comprises a second wire moving plate, which is vertically arranged on the bottom plate, and a plurality of evenly distributed second wire moving devices are arranged on the second wire moving plate.

[0034] Furthermore, the wire assembly includes an upper wire plate, a lower wire plate, and a side plate, wherein the side plate is arranged between the upper wire plate and the lower guide plate, and the side plate is arranged on one side of the upper wire plate, and a wire guide hook is arranged on the side plate.

[0035] A wire detector and an oiled porcelain piece are provided on the lower wire board. The wire detector is arranged in the middle of the lower wire board, and the oiled porcelain piece is arranged at the other end away from the wire guide hook. The positions of the wire detector, the oiled porcelain piece and the wire guide hook correspond and are on the same straight line.

[0036] Compared with the prior art, the acrylic fiber texturing machine described in the utility model has the following advantages:

[0037] 1. The acrylic yarn of the present application runs smoothly: by installing a support tube on the edge of the raw yarn paper tube, the raw yarn does not directly contact the paper tube, so that the raw yarn transitions smoothly, reduces friction, and reduces the risk of broken yarn.

[0038] 2. The present invention prevents excessive deformation and heating when the yarn runs at a low speed: Since the mechanical speed of the acrylic raw yarn false twist is low, it is easy to be overheated when passing through the original heat box at a low speed, making it impossible to achieve a good false twist effect. Therefore, the distance between the two upper heat box hanging angles is shortened, so that the length of the upper heat box is less than 1300-1500mm, so that the raw yarn can pass through the upper heat box faster at a low speed, avoiding the raw yarn staying in the upper heat box for too long, and improving the false twist effect.

[0039] 3. The silk thread of the present application is at a suitable temperature when it reaches the false twister. The upper heat box is installed at a lower position than the original one through the heat box hanging plate, so that the distance between the outlet position of the upper heat box and the upper entrance of the false twister is 400-500mm, shortening the length of the cold rail, thereby avoiding excessive temperature drop of the silk thread after leaving the heat box, thereby achieving the expected elasticizing effect.
