Description

Technical Field

[0001] This utility model relates to the field of chemical fiber manufacturing technology, specifically to a solution-dyed polyester staple fiber drawing and setting device. Background Technology

[0002] Solution dyeing is an environmentally friendly dyeing technology that involves directly adding masterbatch during the production of polyester fibers. It involves uniformly mixing the masterbatch with polyester melt in a screw extruder, followed by melt spinning to form nascent fibers. During production, polyester fibers are sometimes cut into short fibers (typically about 38mm in length) to meet the processing requirements and usage characteristics of different applications. The prior art, disclosed in patent announcement number CN211947381U, describes a solution-dyed polyester staple fiber drawing and setting fixture, comprising a box, a conveying device, and a heating device. Both the conveying device and the heating device are housed within the box. The feeding port is higher than the plane of the highest point of the conveying device, while the discharge port is lower. The heating device is positioned above the conveying device and is used to heat and set the staple fibers on the conveying device. This design solves the problem of traditional drawing and setting devices that use several high-pressure nozzles to inject high-temperature gas into a steam clamp to set the staple fibers. The resulting water droplets from the liquefied high-temperature gas easily cause the staple fibers to become damp, affecting their drawing stability. However, in this equipment, the short fiber material is transported by the active roller, the driven roller, and the conveyor belt. This method cannot guarantee that the short fiber will remain straight when passing through the heating device, which will cause the subsequent products to bend due to internal stress, making them inconvenient for packaging and use. The pressure roller of the device can only play a simple flattening role, and flattening before heating will fix the bending shape of the short fiber, which is not conducive to the stretching and shaping of the short fiber. Therefore, we propose a solution-dyed polyester short fiber stretching and shaping equipment. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a solution-dyed polyester staple fiber drawing and setting device. This device features a reliable conveying and traction unit. A blower delivers airflow through an air duct into the material tube slot. This airflow, upon passing through the heating wire, generates hot air. This hot air not only conveys the polyester staple fiber but also preheats it, improving the heat-drying and setting effect. Furthermore, it has a reliable heat-drying and setting unit that utilizes the blowing airflow and the long, straight structure of the metal tube to straighten the polyester staple fiber. Additionally, a heater heats the metal tube, thereby heating the conveyed polyester staple fiber to evaporate internal moisture and achieve setting. This effectively solves the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solution-dyed polyester staple fiber drawing and setting device, comprising a base, a heat-drying setting unit, and a conveying and traction unit; Base: A rectangular plate; The heat-drying and setting unit includes a filling groove, a limiting groove, a material tube groove, a rubber sleeve, a metal tube, and a heater. The upper end of the base has seven sets of groove structures. Each set of groove structures consists of three sections: a filling groove, a limiting groove, and a material tube groove. The internal cross-section of the three sections is circular, and each has an opening that communicates with the upper side. The diameter of the limiting groove on the middle side is larger than the diameter of the material tube groove on the front side, and the diameter of the material tube groove is larger than the diameter of the filling groove on the rear side. Inside the base, and on the lower side of each material tube groove, a heater is embedded. The heater has an approximately U-shaped structure and surrounds the outside of the material tube groove. The metal tube is installed inside the material tube groove, and a rubber sleeve is tightly fitted on the outer side of its rear end. The rubber sleeve is locked inside the limiting groove. The rear end of the metal tube is aligned with the filling groove and has the same inner diameter as the filling groove. Conveying and traction unit: installed on the left side of the base.

[0005] The filling groove is used for filling polyester staple fibers, and the feed tube slot is used for installing the metal tube. The rubber sleeve placed on the rear end of the metal tube can achieve the effect of longitudinally limiting and locking the metal tube by locking it into the limiting slot. The blower in the conveying and traction unit blows air at the rear end of the filling groove, blowing the polyester staple fibers in the filling groove forward. The polyester staple fibers are conveyed backward along the metal tube. The long and straight structure of the metal tube will straighten the polyester staple fibers. The air blown inside the tube can further traction and stretch the polyester staple fibers. The heater heats the metal tube, thereby heating the polyester staple fibers conveyed inside to evaporate the moisture inside the fibers and promote the shaping of the polyester staple fibers.

[0006] Furthermore, the heat-drying and setting unit also includes clamping blocks, a pressure frame, and a locking block. A set of clamping blocks is fixedly connected to the left side of the base, corresponding laterally to the limiting slot. The left end of the pressure frame is rotatably connected to the clamping blocks via a short shaft. The pressure frame has a flat, elongated inverted U-shaped structure, with its long, straight horizontal section pressing against the upper side of each rubber sleeve. A locking block is fixedly connected to the right side of the base, corresponding laterally to the limiting slot. The right end of the pressure frame engages with the locking block through a locking hole inside. The clamping blocks are used to lock the left end of the pressure frame, and the shaft at the end of the pressure frame allows it to rotate. The pressure frame is fixed by fastening itself to the locking block on the right side, thereby pressing and fixing the rubber sleeves, further improving the fixing effect on the metal tubes. By opening the pressure frame, the metal tubes installed inside the tube slot can be replaced to accommodate polyester staple fibers of different thicknesses.

[0007] Furthermore, the conveying and traction unit includes a blower, air supply pipes, heating wires, dustproof nets, and single-control buttons. The blower is fixedly installed on the rear side of the base, and seven air supply pipes are fixedly connected to the front end of the blower. The seven air supply pipes are respectively inserted into the rear end of the packing groove. Heating wires are installed inside the air supply pipes. The air inlet of the blower is located on the rear side, and a dustproof net is installed at the port. Seven single-control buttons are installed on the upper side of the blower. The heating wires in each air supply pipe and the corresponding heaters on the front side form a group of heating devices, and the input end of each group of heating devices is electrically connected to the output end of an external power supply through a single-control button. The blower blows air into the material tube slot through the air supply pipe. When the air passes through the heating wire, it forms hot air. The hot air can blow the polyester staple fiber and preheat it at the same time, thereby improving the heat drying and forming effect of the polyester staple fiber. The dustproof net can prevent dust in the outside air from entering the filling tank. The number of heating devices that can be turned on can be controlled by a single control button, so that the heating devices in the corresponding tank can be turned on according to the processing requirements to achieve energy saving.

[0008] Furthermore, the conveying and traction unit also includes guide blocks, movable cover plates, vertical baffles, and mounting brackets. On the upper side of the base, and on both the left and right sides at the port of each filling groove, a set of guide blocks is fixedly connected. Each set of guide blocks has a chamfered structure on the opposite side. A movable cover plate is slidably connected to the upper side of the guide blocks. The movable cover plate has seven elongated through holes inside. Each elongated through hole corresponds vertically to a filling groove, and the width of the solid part between two adjacent elongated through holes is greater than the opening width between each set of guide blocks. A vertical baffle is fixedly connected to the front side of the movable cover plate and fits against the front side of each set of guide blocks. An L-shaped mounting bracket is fixedly connected to the left and right sides of the base at a position corresponding to the horizontal direction of the filling groove. The chamfered structure of the guide block can form a V-shaped channel, which facilitates the polyester staple fiber to slide into the filling groove from the top. The movable cover plate can seal the upper port of the guide block, and the vertical baffle can seal the front opening of the guide block. In this way, when blowing materials, the air force is prevented from escaping outward from the opening at the guide block, so as to ensure the blowing effect on the polyester staple fiber.

[0009] Furthermore, the conveying and traction unit also includes telescopic rods and a hydraulic cylinder. A hydraulic cylinder is fixedly installed at the middle position of the left mounting bracket. The telescopic end of the hydraulic cylinder is laterally fixedly connected to the left end of the movable cover plate. Two telescopic rods, one in front and one behind, are fixedly connected to the right end of the movable cover plate. The right end of each telescopic rod is fixedly connected to the right mounting bracket. The right mounting bracket is used for installing the telescopic rods, which allow the movable cover plate to slide only laterally. The left mounting bracket is used for installing the hydraulic cylinder, which provides the power required for the lateral sliding of the movable cover plate. After one feeding operation is completed, the hydraulic cylinder pushes the movable cover plate to the right, using the solid part of the movable cover plate to seal the port of the guide block. After the polyester staple fibers are blown outwards, the hydraulic cylinder drives the movable cover plate to return to its original position to the left, exposing the port of the guide block for easy feeding the next time.

[0010] Furthermore, the conveying and traction unit also includes a pressure sensor and a PLC controller. The pressure sensor is installed on the inward-facing vertical end face of the right mounting bracket, and the PLC controller is installed on the outward-facing vertical end face of the left mounting bracket. Both the pressure sensor and the input terminals of the hydraulic cylinder are electrically connected to the output terminal of an external power supply via the PLC controller. The pressure sensor is used to detect whether the right end of the movable cover has moved to its right position, thus facilitating the PLC controller's control of the hydraulic cylinder's start and stop.
