Description

Technical Field

[0001] This utility model relates to a recycling and reprocessing system for yarn waste tubes formed in continuous spinning processes, and more particularly to a recycling and reprocessing system based on monofilament twisting for yarn waste tubes formed in continuous spinning processes, which enables individual filaments to obtain a certain twist, so that they have certain mechanical properties and appearance after twisting, and belongs to the field of continuous spinning viscose filament production technology. Background Technology

[0002] In continuous viscose filament production, continuous spinning machines, such as the KR / HD340 model, complete processes like filament solidification, washing, oiling, and bobbin forming, with the finished product existing in the form of yarn bobbins. However, due to production processes, equipment issues, or maintenance, defective yarn bobbins (substandard products) that do not meet requirements are generated. Currently, these defective yarn bobbins mainly fall into two categories: 1. Yarn bobbins whose physical properties (primarily weight) do not meet conventional yarn bobbin standards, generally formed by premature filament breakage; 2. Yarn bobbins whose chemical properties (primarily strength, elongation, maximum coefficient of friction, and residual grease content) do not meet conventional yarn bobbin standards, generally discovered during subsequent finished product testing.

[0003] Since waste yarn bobbins do not meet the requirements of downstream processes, they are generally treated as waste yarn. If only treated in this way, the profit will be greatly reduced compared to yarn bobbins (genuine products), and the materials will not be used effectively.

[0004] Although the prior art CN214655457U discloses "a waste yarn recycling and processing device", it mainly separates the yarn from the waste filaments, with the waste filaments falling into a waste filament box and the yarn being collected separately; CN111842421A discloses "a waste weft knitted fabric yarn recycling device and method", which, through pretreatment, unraveling, skeining, drying, sorting, winding and packaging, is mainly designed to address the damage to fiber length and strength caused by traditional unraveling, and ensures the fiber strength retention rate and fiber length retention rate in the unraveled yarn.

[0005] Therefore, a recycling system for waste yarn produced in continuous spinning processes is needed to achieve waste reuse and improve economic value. Summary of the Invention

[0006] Aiming to overcome the shortcomings of existing technologies, a recycling and reprocessing system suitable for yarn waste products generated in continuous spinning processes is proposed. In this technical solution, existing winding machines, twisting machines, and setting steaming machines are combined, and their corresponding structures are adapted to form a production line suitable for twisting single viscose filaments from yarn waste products. This gives the yarn in the waste products a certain twist, increasing its properties, such as strength, thus turning yarn waste into valuable resources and meeting the needs of industrial production.

[0007] To achieve the above technical objectives, the following technical solution is proposed:

[0008] A recycling and reprocessing system for waste yarn bobbins formed in continuous spinning processes includes a winding machine, a doubling machine, and a setting steaming machine arranged in sequence.

[0009] Winding machine: includes overfeed device, tension device, oiling device and winding device I. A yarn waste tube placement platform is provided in front of the overfeed device station. The tension device is located behind the overfeed device station. The oiling device is located behind the tension device station. The winding device is located behind the oiling device station. The shell tube is sleeved on the winding device I. The yarn waste tube placement platform, overfeed device, tension device, oiling device and winding device I form a continuous passage for processing yarn waste tubes into shell tubes.

[0010] The overfeed device includes a wire guide hook I, a wire guide bar, a wire breakage sensor I, an overfeed wheel, and a wire splitter arranged in sequence.

[0011] The tensioning device includes a guide hook II and a comb-type tensioner arranged in sequence;

[0013] Winding device I includes wire guide I;

[0014] Furthermore, the comb-type tensioner includes a fixed frame, a movable frame, and a pressure arm. The fixed frame has evenly distributed pressure fingers I. The movable frame is located on the opposite side of the fixed frame, and the movable frame has evenly distributed pressure fingers II that cooperate with the pressure fingers I. A through hole is formed between the pressure fingers I and pressure fingers II for clamping the yarn. One end of the pressure arm is fixed to the top of the movable frame, and the other end extends to the outside of the fixed frame. The end of the pressure arm is connected to a counterweight placement plate via a suspension rope. The comb-type tensioner, similar to a "hairpin," firmly clamps the yarn in the middle, providing stable tension and preventing problems such as yarn breakage and uneven bobbin tension caused by tension fluctuations. This tensioner is also easy to adjust in terms of tension and has stable performance. The movable frame is connected to a weight-bearing counterweight via a suspension rope, and the clamping degree between the movable and fixed frames can be controlled by adjusting the weight of the counterweight, thereby adjusting the tension. The tighter the clamp, the greater the tension, and vice versa.

[0015] Preferably, the contact surfaces of the pressure fingers I and II with the yarn are both smooth, rounded surfaces. This design prevents the yarn from getting fuzzy.

[0016] Preferably, the fixed frame and the movable frame are movably connected by a connecting rod.

[0017] The doubling twister includes a twisting device, a tension adjusting device, and a winding device II. The shell canister is fitted onto the twisting device, which is located in front of the tension adjusting device. The winding device II is located behind the tension adjusting device. The doubling twister is fitted onto the winding device II. The twisting device, the tension adjusting device, and the winding device II form a continuous passage for processing the shell canister into a doubling twister.

[0018] In addition, a breakage detection device is provided between the twisting device and the tension adjustment device;

[0019] The twisting device includes a liner, which has a steel ring and a central hole at the top and a twisting disc at the bottom; the shell tube is fitted onto the liner;

[0020] The broken head detection device includes a gas ring hole, a guide wheel, and a tension bar arranged in sequence;

[0021] The tension adjustment device includes a guide roller and an overfeed roller arranged in sequence.

[0022] The winding device II includes a yarn guide II and a twisting drum support arranged sequentially. The left top plate of the twisting drum support has evenly distributed notches I for cutting yarn along its edge, extending towards the center of the left top plate; the right top plate of the twisting drum support has evenly distributed notches II for cutting yarn along its edge, extending towards the center of the right top plate; the twisting drum support is equipped with a yarn breakage sensor for detecting the cut yarn. Preferably, the shape and size of the left and right top plates are consistent. Furthermore, the diameter of both the left and right top plates is 75-85 mm.

[0023] A setting steaming machine includes a housing, a setting trolley for holding the twisting cylinder, and a placement frame for holding the setting trolley. A cavity is formed inside the housing to accommodate the setting trolley and the placement frame. A feed sealing door is provided on one side of the housing, and a discharge sealing door is provided on the other side. The cavity is connected to a vacuum pipe, a steam pipe, and a chemical spraying pipe. The spray nozzles on the chemical spraying pipe are distributed in the middle and / or rear of the cavity.

[0024] Furthermore, a heating coil is provided in the inner cavity of the housing, and the heating coil is connected to a steam pipe;

[0025] Preferably, the housing is mounted on a column, and a lifting platform for discharging the shaping trolley is provided on the rear side of the discharge sealing door.

[0026] Preferably, the vacuum tube is equipped with a vacuum pump, and the steam tube is equipped with a regulating valve.

[0027] In this technical solution, the "sequential arrangement" specifically refers to the arrangement of each equipment component in accordance with the process (i.e. the direction of the yarn), showing the positional relationship of each equipment component, and ensuring the smooth progress of the yarn processing technology.

[0028] The positional relationships involved in this technical solution, such as "front side of workstation", "rear side of workstation", "upper", "one end", "the other end", "upper part", "lower part", "between", "one side", "the other side", "inner", "middle part", and "rear part", are defined according to the actual usage conditions and are conventional terms in this technical field, as well as conventional terms used by those skilled in the art in actual use.

[0029] The beneficial technical effects of adopting this technical solution are as follows:

[0030] This invention combines existing winding machines, doubling machines, and setting steaming machines, and adapts the corresponding structures to form a production line suitable for twisting single viscose filaments in yarn waste bobbins. This gives the yarn in the waste bobbins a certain twist, increasing its properties such as strength, elasticity, and toughness. In other words, it turns yarn waste bobbins into valuable resources, meeting the needs of industrial production. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0045] Example 1

[0046] A recycling and reprocessing system suitable for yarn waste bobbins 4 formed in continuous spinning processes, such as Figure 1 As shown, it includes a winding machine 1, a doubling machine 2, and a shaping steaming machine 3 arranged in sequence;

[0047] Winding machine 1: such as Figure 2As shown, it includes an overfeed device 12, a tension device 13, an oiling device 14, and a winding device I 15.

The oiling device 14 is located behind the tension device 13. The winding device is located behind the oiling device 14. The shell tube 5 is sleeved on the winding device I 15. A continuous passage is formed between the yarn waste tube placement platform 11, the overfeed device 12, the tension device 13, the oiling device 14, and the winding device I 15 to process the yarn waste tube 4 into the shell tube 5.

[0048] Twisting machine 2: such as Figure 4 As shown, it includes a twisting device 21, a tension adjusting device 22, and a winding device II 23. The shell tube 5 is sleeved on the twisting device 21. A breakage detection device 24 is provided between the twisting device 21 and the tension adjusting device 22. The twisting device 21 is located in front of the working position of the tension adjusting device 22, and the winding device II 23 is located behind the working position of the tension adjusting device 22. The double twisting cylinder 6 is sleeved on the winding device II 23. A continuous passage is formed between the twisting device 21, the tension adjusting device 22, and the winding device II 23 to process the shell tube 5 into the double twisting cylinder 6.

[0049] Setting and steaming machine 3: such as Figure 7 As shown, the shaping steaming machine 3 includes a housing 31, a shaping trolley 32 for placing the twisting cylinder 6, and a placement frame 33 for placing the shaping trolley 32. A cavity is formed inside the housing 31 to accommodate the shaping trolley 32 and the placement frame 33. A feed sealing door 34 is provided on one side of the housing 31, and a discharge sealing door 35 is provided on the other side. A vacuum pipe 36, a steam pipe 37, and a chemical spraying pipe 38 are connected to the cavity.

[0050] First, this embodiment combines existing winding machine 1, twisting machine 2, and setting steaming machine 3. Second, the corresponding structural components are arranged adaptively to form a production line suitable for twisting single viscose filaments in yarn waste bobbins 4.

[0051] Example 2

[0052] Based on Example 1, this example further defines the overfeed device 12, tension device 13, oiling device 14, and winding device I 15 in the winding machine 1 to further illustrate the technical solution.

[0053] like Figure 2As shown, the overfeed device 12 includes a guide hook I 120, a guide bar 121, a breakage sensor I 122, an overfeed wheel 123, and a yarn splitter 124 arranged in sequence; the tension device 13 includes a guide hook II 130 and a comb-type tensioner 131 arranged in sequence; the oiling device 14 includes an oil wheel 140 and a breakage sensor II 141 arranged in sequence; and the winding device I 15 includes a yarn guide I 150.

[0054] By arranging each component in a specific way, the winding process is ensured to proceed smoothly and stably, effectively preparing for the subsequent twisting of the yarn waste bobbin 4.

[0055] Example 3

[0056] Based on Example 2, this example further defines the comb tensioner 131 to further illustrate the technical solution.

[0057] like Figure 3 As shown, the comb-type tensioner 131 includes a fixed frame 1310, a movable frame 1311, and a pressure arm 1312. The fixed frame 1310 has evenly distributed pressure fingers I 1313. The movable frame 1311 is located on the opposite side of the fixed frame 1310, and the movable frame 1311 has evenly distributed pressure fingers II 1314 that cooperate with the pressure fingers I 1313. A through hole for pressing the yarn is formed between the pressure fingers I 1313 and pressure fingers II 1314. One end of the pressure arm 1312 is fixed to the top of the movable frame 1311, and the other end extends to the outside of the fixed frame 1310. The end of the pressure arm 1312 is connected to a counterweight placement plate 1315 via a suspension rope 1316. The comb-type tensioner 131, similar to a "hairpin," firmly presses the yarn in the middle, providing stable tension and preventing problems such as yarn breakage and uneven bobbin tension caused by tension fluctuations. Furthermore, this tensioner allows for easy adjustment of the tension and has stable performance. The movable frame 1311 is connected to a load-bearing hammer via a suspension rope 1316. The clamping degree between the movable frame 1311 and the fixed frame 1310 can be controlled by adjusting the weight of the hammer, thereby adjusting the tension. The tighter the clamp, the greater the tension, and vice versa.

[0058] Preferably, the contact surfaces of the pressure fingers I 1313 and II 1314 with the yarn are both smooth, rounded surfaces. This design prevents the yarn from getting fuzzy.

[0059] Preferably, the fixed frame 1310 and the movable frame 1311 are movably connected by a connecting rod 1317.

[0060] Preferably, the end of the pressure arm 1312 is provided with a pulley 1318, and the suspension rope 1316 is sleeved on the pulley 1318. The length of the suspension rope 1316 can be adjusted as needed.

[0061] Example 4

[0062] Based on Examples 1-3, this example further defines the twisting device 21, the breakage detection device 24, the tension adjustment device 22, and the winding device II 23 in the double twister 2, in order to further explain the technical solution.

[0063] like Figure 4 As shown, the twisting device 21 includes a liner 210, which has a steel ring and a central hole on the upper part and a twisting disc on the lower part; the shell tube 5 is fitted on the liner 210.

[0064] The broken head detection device 24 includes a gas ring hole 240, a guide wheel 220 and a tension bar 242 arranged in sequence;

[0065] The tension adjustment device 22 includes a guide roller 220 and an overfeed roller 221 arranged in sequence.

[0066] The winding device II 23 includes a yarn guide II 230 and a twisting drum support 243 arranged sequentially. Preferably, the shape and size of the left top plate 244 and the right top plate 245 on the twisting drum support 243 can be consistent, for example, the left top plate 244 on the twisting drum support 243 has evenly distributed notches I 246 for cutting yarn (e.g., ...). Figure 5 As shown), notch I 246 extends towards the center of the left top plate 244; notches II 247 for cutting yarn are evenly distributed along the edge of the right top plate 245 on the twisting cylinder support 243 (as shown). Figure 6 As shown), notch II 247 extends towards the center of the right top plate 245; a yarn breakage sensor for detecting the yarn being cut is provided on the twisting cylinder support 243. In one embodiment, the opposite sides of notch I 246 and notch II 247 can be set in a knife-edge shape 248 (i.e., inclined to the contact surface with the yarn) to facilitate cutting.

[0067] In addition, the diameter of the left top plate 244 is 75-85mm, and the diameter of the right top plate 245 is 75-85mm, which is larger than the diameter of the existing top plates, effectively preventing the thread from "running" outward and affecting the operation of the bearing.

[0068] By specifically arranging each component, the twisting process is ensured to proceed smoothly and stably, effectively changing the twist of the waste yarn, thus altering its properties and increasing its subsequent utilization value. Furthermore, due to the poor inherent properties of the waste yarn, its breakage rate increases during recycling. Broken waste yarn easily gets tangled in the bearings of the top plate, causing winding jams. This increases the probability of the twisting cylinder 6 falling off; moreover, after jamming, the winding tension increases, making it difficult to twist the waste yarn. Therefore, by further restricting the structure of the left and right top plates in the winding device II23, specifically by setting notches I246 and II247, broken waste yarn is promptly cut. Simultaneously, a yarn breakage sensor alarms, allowing workers to promptly detect and clean up broken waste yarn, improving the smooth and orderly operation of the twisting process.

[0069] Example 5

[0070] Based on Examples 1-4, this example further defines the shaping steaming machine 3 to further illustrate the technical solution.

[0071] A heating coil 39 is provided in the inner cavity of the housing 31, and the heating coil 39 is connected to the steam pipe 37;

[0072] As a preferred embodiment, the housing 31 is mounted on the column 40, and a lifting platform 41 for discharging the shaping trolley 32 is provided on the rear side of the discharge sealing door 35.

[0073] As a preferred embodiment, a vacuum pump 42 is provided on the vacuum tube 36, and a regulating valve 43 is provided on the steam tube 37.
