The device includes a lower protective cylinder with an upper cylinder fixedly mounted at its upper end. Yarn bodies penetrate the inner cavities of both the lower and upper protective cylinders. A negative ion emitting mechanism is installed at the bottom of the inner cavity of the lower protective cylinder. The device comprises the following raw materials and their weight fractions: high-strength nylon, polyester, polyethylene fiber, carbon fiber bundles, and elastic fiber.

Description

Technical Field

[0001] This invention relates to the field of yarn production technology, specifically to a high-temperature texturing device for solid-color yarn and a method for preparing protective gloves thereon. Background Technology

[0002] Solid-color yarn is a type of yarn with a special color effect, mainly produced by blending two or more fibers of different colors through a specific spinning process. During production, the yarn needs to be texturized using a texturing machine to give it a certain degree of elasticity.

[0003] Chinese invention patent application CN109023615B discloses a texturing machine, including a yarn feeding device, a heating device, a cooling device, a false twister, an oil soaking device, and a yarn taking-up device. When texturing yarn using this machine, the yarn feeding device conveys the yarn to the heating device for heating, then the cooling device cools the yarn, followed by twisting the yarn using the false twister, then oil soaking the yarn, and finally, the yarn taking-up device collects the oil-soaked yarn, thus achieving the yarn texturing process.

[0004] While the above solution can meet the requirements for texturing yarn, it still has certain drawbacks. When oiling the yarn, it is done by passing it through an oil tank containing oil. However, this continuous oiling process, with the oil in the tank remaining stagnant for an extended period, allows the active ingredients, such as lubricants and antistatic agents, to settle, leading to uneven oil concentration, reduced efficiency, and severely impacting the oiling effect and consistency on the yarn. Furthermore, during the oiling process, the yarn contacts the anti-slip strips on the guide wheel, and the oil is slowly injected into the tank through friction between the strips and the yarn. This mechanical contact method is highly susceptible to damage, increasing fuzz, and disrupting the soft, hazy texture of the yarn surface. Friction can also cause unwanted displacement or pilling of fibers of different colors, affecting the uniform visual effect of color mixing. Summary of the Invention

The upper end of the rotating circular tube is fixedly connected to the conical rotating seat. Multiple helical blades are fixedly connected to the side of the conical rotating seat in a circular array. The driving mechanism is installed at the lower end of the rotating circular tube.

[0010] As a further embodiment of the present invention, a scraper is fixedly installed at the lower end of the conical rotating seat. The scraper rotates along the outer side of the conical seat, the inner side wall of the annular groove, and the side wall of the upper cylinder cavity.

[0011] As a further embodiment of the present invention, a support block is fixedly connected to the inner sidewall of the annular plate, the rotating tube passes through the support block, and the rotating tube is rotatably connected to the support block through a bearing, and the driving mechanism is fixedly installed at the lower end of the support block.

[0012] As a further embodiment of the present invention, the driving mechanism includes a protective box fixedly installed at the lower end of the support block. The lower end of the rotating round tube passes through the protective box downwards, and the rotating round tube and the protective box are rotatably connected by a bearing.

[0013] As a further embodiment of the present invention, the auxiliary oiling mechanism includes an oiling seat fixedly connected to the upper end of the inner cavity of the upper cylinder.

[0014] A method for preparing a solid-color yarn protective glove includes the following raw materials and their weight fractions: 25%-35% high-strength nylon, 25%-35% polyester, 20%-35% polyethylene fiber, 3%-8% carbon fiber bundle, and 3%-8% elastic fiber; the above raw materials are mixed in proportion. Protective glove preparation steps: Step 1: Using polyethylene fiber as the core yarn, the mixed colored matrix fibers are evenly wrapped around the outside of the core yarn through air-jet spinning or Siro spinning to make a mixed-color yarn. This gives the outer layer a soft and hazy mixed-color effect, while the inner layer provides strong protection. The carbon fiber bundles are not exposed, keeping the gloves aesthetically pleasing. Step 2: Immerse the mixed-color yarn in a mixture containing abrasion-resistant agent, waterproof agent, and flame retardant, and squeeze it through rollers.

Place the woven protective glove blank onto the hand mold and set it with steam or hot air to obtain a stable and fit hand shape. Step 4: Apply or dip polyurethane, nitrile rubber or latex to the palm area of ​​the protective glove to form a non-slip, wear-resistant and oil-resistant granular or patterned coating, so that the color effect after coating is faintly visible, forming a unique aesthetic. Step 5: Finally, conduct tests on protective properties such as abrasion resistance and antistatic properties. After the tests are completed, package and store the qualified protective gloves.

[0015] The beneficial effects of this invention are: 1. The negative ions generated by the negative ion emission mechanism can act evenly on the yarn body. The yarn body carrying negative ions quickly enters the conical oiling chamber. Oil mist is sprayed into the conical oiling chamber through the ultrasonic atomizing nozzle. Then, the spiral blades rotate to form an upward spiral airflow in the conical oiling chamber. When the oil mist enters the conical oiling chamber, it is driven upward spiral by the spiral airflow. When the yarn body carrying negative ions enters the conical oiling chamber, the oil mist will continuously wash and wrap the yarn body from all directions and angles with the spiral airflow, so that the yarn body can be evenly contacted with the oil mist. At the same time, because the yarn body carries negative ions, the oil mist can be well adsorbed on the yarn body, completing the uniform oiling operation.

[0016] 2. When oiling the yarn body, the remaining oil mist will flow outward along the air outlet pipe for recycling; at the same time, some oil mist and oil droplets will adhere to the conical upper oil chamber, and the oil will drip down onto the outer side of the conical seat and the inner wall of the upper cylinder after it collects; when the conical rotating seat rotates, it will drive the scraper to rotate synchronously, and the scraper will scrape off the oil on the outer side of the conical seat and the inner wall of the upper cylinder, so that the oil enters the annular groove, and then the scraper pushes the oil in the annular groove into the oil outlet pipe, so that the oil is discharged and recycled.

[0020] Please see Figures 1 to 7 The present invention provides a technical solution: a high-temperature texturing device for solid-color yarn, including a protective lower cylinder 1, an upper cylinder 11 fixedly installed at the upper end of the protective lower cylinder 1, the upper end of the protective lower cylinder 1 being open, the lower end of the upper cylinder 11 being open, a yarn body 8 penetrating through the inner cavity of both the protective lower cylinder 1 and the upper cylinder 11, a round hole being opened at the lower end of the protective lower cylinder 1 and the upper end of the upper cylinder 11, the yarn body 8 passing through the round hole, and the yarn body 8 not contacting the protective lower cylinder 1 and the upper cylinder 11, a negative ion emitting mechanism being installed at the bottom of the inner cavity of the protective lower cylinder 1, the negative ion emitting mechanism being sleeved on the outside of the yarn body 8; An annular plate 31 is installed at the lower end of the inner cavity of the upper cylinder 11. A conical seat 3 is fixedly connected to the upper end of the annular plate 31. An annular groove 32 is opened on the outer side of the upper end of the annular plate 31. An annular recessed cavity is formed between the annular plate 31 and the inner wall of the upper cylinder 11. The annular recessed cavity is used to collect oil. The inner cavities of the lower cylinder 1 and the upper cylinder 11 are separated by the cooperation of the conical seat 3 and the annular plate 31. A screw drive mechanism is rotatably mounted on the upper end of the conical seat 3, and a drive mechanism is mounted on the lower end of the screw drive mechanism. The drive mechanism is used to drive the screw drive mechanism to rotate. The conical seat 3, the annular plate 31 and the screw drive mechanism are all sleeved on the outside of the yarn body 8, and the conical seat 3, the annular plate 31 and the screw drive mechanism do not contact the yarn body 8. An auxiliary oiling mechanism is installed at the upper end of the inner cavity of the upper cylinder 11. Multiple oil inlet pipes 7 are fixedly inserted through the side of the upper cylinder 11 in a ring array. The upper end of the oil inlet pipe 7 is bent upward at an angle. An ultrasonic atomizing nozzle 71 is fixedly installed at the upper end of each oil inlet pipe 7. The ultrasonic atomizing nozzles 71 are distributed at an angle. Multiple ultrasonic atomizing nozzles 71 are distributed in a ring array on the outer side of the spiral drive mechanism. The end of the oil inlet pipe 7 away from the ultrasonic atomizing nozzle 71 is connected to the output end of the ultrasonic atomizing device.

[0021] Oil is introduced into multiple oil inlet pipes 7 through an ultrasonic atomizing device, and finally the oil is sprayed out along the ultrasonic atomizing nozzle 71 to form an oil mist.

[0022] Please see Figure 2 , Figure 4 and Figure 5 The negative ion emitting mechanism includes a mounting bracket 12 fixedly installed at the bottom of the inner cavity of the protective lower cylinder 1. Multiple negative ion emitting rings 2 are fixedly installed at equal intervals from top to bottom on the inner side of the mounting bracket 12. The negative ion emitting rings 2 are sleeved on the outer side of the yarn body 8. Multiple conductive pins 21 are fixedly inserted into the inner side of each negative ion emitting ring 2 in a ring array. A negative ion emitting unit 22 is installed on the outer side of each conductive pin 21. The multiple negative ion emitting units 22 on the inner side of each negative ion emitting ring 2 are distributed in a ring array on the outer side of the yarn body 8. The negative ion emitting unit 22 can be made of carbon fiber bundle.

[0023] Multiple negative ion emitting rings 2 are connected in parallel. Each negative ion emitting ring 2 is equipped with an independent, low-power negative ion generating module. The input terminals of all modules are connected in parallel to the same low-voltage DC power supply to ensure that each emitting ring obtains the same and stable operating voltage as much as possible, so that each negative ion emitting unit 22 can stably generate a large number of negative ions. The yarn body 8 is transported from bottom to top. The yarn body 8 enters from the lower end of the protective lower bobbin 1, passes through the negative ion emission mechanism, the spiral drive mechanism, and the auxiliary oiling mechanism in sequence from bottom to top, and finally exits from the upper end of the upper bobbin 11. When the yarn body 8 passes through the inside of the multiple negative ion emitting rings 2, the negative ions generated by the negative ion emitting unit 22 can act evenly on the yarn body 8, so that the yarn body 8 can be safely and gently charged.

[0024] Please see Figure 4 and Figure 6 The lower end of the upper cylinder 11 is provided with multiple docking slots 13 in a ring array. Multiple docking blocks 33 are fixedly connected to the outer side of the annular plate 31 in a ring array. The docking blocks 33 are engaged with the adjacent docking slots 13, and the lower side of the docking blocks 33 abuts against the upper end of the lower protective cylinder 1.

[0025] During assembly, the docking block 33 is inserted into the docking groove 13, and then the upper cylinder 11 and the lower protective cylinder 1 are fixedly connected, thereby firmly inserting the docking block 33 into the docking groove 13, so that the annular plate 31 can be firmly installed in the inner cavity of the upper cylinder 11. Alternatively, the annular plate 31 can be directly fixed in the inner cavity of the upper cylinder 11 through flanges or other means, ensuring that the annular plate 31 and the inner cavity of the upper cylinder 11 are sealed and fixedly connected.

[0026] Please see Figure 2 , Figure 4 , Figure 6 and Figure 7 The screw drive mechanism includes a rotating round tube 4 that is inserted through the upper end of the conical seat 3. The rotating round tube 4 and the conical seat 3 are rotatably connected by bearings. A conical rotating seat 41 is fixedly connected to the upper end of the rotating round tube 4. Multiple helical blades 42 are fixedly connected to the side of the conical rotating seat 41 in a ring array. The drive mechanism is installed at the lower end of the rotating round tube 4.

[0027] The upper end of the conical rotating seat 41 has a circular hole extending from top to bottom. The yarn body 8 passes through the circular hole, and the yarn body 8 does not contact the conical rotating seat 41.

[0028] Please see Figures 2 to 4 , Figure 6 and Figure 7 A scraper 5 is fixedly installed at the lower end of the conical rotating seat 41. The scraper 5 rotates along the outer side of the conical seat 3, the inner side wall of the annular groove 32, and the side wall of the inner cavity of the upper cylinder 11. An oil outlet pipe 14 is fixedly connected to the side of the upper cylinder 11. The oil outlet pipe 14 is connected to the annular groove 32 and is connected to the oil recovery device through pipes, etc.

[0029] The oil on the outer side of the conical seat 3 and the inner wall of the upper cylinder 11 is scraped off by the scraper 5, so that the oil collects in the annular groove 32.

[0030] Please see Figure 2 , Figure 4 and Figure 7 A support block 34 is fixedly connected to the inner wall of the annular plate 31. The rotating tube 4 passes through the support block 34 and is rotatably connected to the support block 34 through a bearing. The yarn body 8 passes through the inner cavity of the rotating tube 4 and does not contact the rotating tube 4. The drive mechanism is fixedly installed at the lower end of the support block 34.

[0031] An air inlet pipe can be inserted through the side of the upper cylinder 11, through which clean air is introduced into the inner cavity of the upper cylinder 11.

[0032] When the rotating tube 4 rotates, it rotates along the conical seat 3 and the support block 34, thereby enabling the rotating tube 4 to rotate stably. The rotating tube 4 drives the conical rotating seat 41 to rotate, and the conical rotating seat 41 drives the spiral blade 42 on its side to rotate, so that the spiral blade 42 causes the inner cavity of the upper cylinder 11 to form an upward spiral airflow. When the oil mist enters the inner cavity of the upper cylinder 11, it is driven upward by the spiral airflow and enters the auxiliary oiling mechanism. When the yarn body 8 carrying negative ions enters the auxiliary oiling mechanism, the oil mist will continuously wash and wrap the yarn body 8 from all directions and angles with the spiral airflow, so that the yarn body 8 can be evenly contacted with the oil mist. At the same time, because the yarn body 8 carries negative ions, the oil mist can be well adsorbed on the yarn body 8, thus completing the uniform oiling operation.

[0033] To improve the oil mist application effect, a positive ion emission device can be installed at the upper end of the ultrasonic atomizing nozzle 71 or the lower end of the auxiliary oiling mechanism to make the oil mist positively charged, so that the oil mist can be better adsorbed with the yarn body 8 and improve the oiling effect.

[0034] Please see Figure 2 , Figure 4 and Figure 7 The drive mechanism includes a protective box 43 fixedly installed at the lower end of the support block 34. The lower end of the rotating round tube 4 passes through the protective box 43 downwards, and the rotating round tube 4 and the protective box 43 are rotatably connected by bearings. A synchronous bevel gear 44 is fixedly sleeved on the outer side of the rotating round tube 4 inside the protective box 43. A transmission bevel gear 45 meshes with the side of the synchronous bevel gear 44. A round shaft 46 is fixedly connected to the side of the transmission bevel gear 45. The end of the round shaft 46 away from the transmission bevel gear 45 passes through the protective box 43 and the lower protective cylinder 1 in sequence. The round shaft 46 is rotatably connected to the protective box 43 and the lower protective cylinder 1 by bearings, and the round shaft 46 is rotatably sealed to the protective box 43 and the lower protective cylinder 1. The round shaft 46 is driven by the motor shaft of a servo motor fixedly installed on the outer side of the lower protective cylinder 1.

[0035] When it is necessary to rotate the rotating tube 4, the motor shaft of the servo motor drives the rotating shaft 46 to rotate, the rotating shaft 46 drives the transmission bevel gear 45 to rotate, the transmission bevel gear 45 drives the synchronous bevel gear 44 to rotate, and the synchronous bevel gear 44 drives the rotating tube 4 to rotate.

[0036] Please see Figure 2 The auxiliary oiling mechanism includes an oiling seat 6 fixedly connected to the upper end of the inner cavity of the upper cylinder 11. The lower end of the oiling seat 6 has a conical oiling cavity 61, and the upper end of the conical oiling cavity 61 has a cylindrical cavity 62. An air outlet pipe 63 is fixedly inserted through the side of the upper cylinder 11. The air outlet pipe 63 extends into the upper oiling seat 6 and communicates with the inner cavity of the cylindrical cavity 62.

[0037] The conical rotating seat 41, the spiral blade 42, and the ultrasonic atomizing nozzle 71 are all located at the lower end of the conical upper oil cavity 61. When the oil mist enters the conical upper oil cavity 61, it is pushed upward along the conical upper oil cavity 61 by the conical rotating seat 41 and the spiral blade 42. At the same time, the oil mist will gradually approach the yarn body 8 in the conical upper oil cavity 61, so that the oil mist can be evenly attached to the yarn body 8. The remaining oil mist will flow out along the air outlet 63 for recycling and reuse.

[0038] Some oil mist and droplets will adhere to the conical upper oil cavity 61. After the oil collects, it will drip down onto the outer side of the conical seat 3 and the inner side wall of the upper cylinder 11. Then, the scraper 5 will scrape off the oil on the outer side of the conical seat 3 and the inner side wall of the upper cylinder 11, so that the oil enters the annular groove 32. Then, the scraper 5 will push the oil in the annular groove 32 into the oil outlet pipe 14, thereby discharging the oil for recycling.

[0039] A method for preparing a solid-color yarn protective glove includes the following raw materials and their weight fractions: 25%-35% high-strength nylon, 25%-35% polyester, 20%-35% polyethylene fiber, 3%-8% carbon fiber bundle, and 3%-8% elastic fiber; the above raw materials are mixed in proportion. Protective glove preparation steps: Step 1: Using polyethylene fiber as the core yarn, the mixed colored matrix fibers are evenly wrapped around the outside of the core yarn through air-jet spinning or Siro spinning to make a mixed-color yarn. This gives the outer layer a soft and hazy mixed-color effect, while the inner layer provides strong protection. The carbon fiber bundles are not exposed, keeping the gloves aesthetically pleasing. Step 2: Immerse the mixed-color yarn in a mixture containing abrasion-resistant agent, waterproof agent, and flame retardant, and squeeze it through rollers. After the impregnation is completed, dry and shape it. Step 3: Based on the 3D model of the hand, develop a weaving program to weave the above-mentioned solid-color yarn into protective gloves. Place the woven protective glove blank onto the hand mold and set it with steam or hot air to obtain a stable and fit hand shape. Step 4: Apply or dip polyurethane, nitrile rubber or latex to the palm area of ​​the protective glove to form a non-slip, wear-resistant and oil-resistant granular or patterned coating, so that the color effect after coating is faintly visible, forming a unique aesthetic. Step 5: Finally, conduct tests on protective properties such as abrasion resistance and antistatic properties. After the tests are completed, package and store the qualified protective gloves.

[0040] Working principle: The yarn body 8 is fed into the heating device for heating, the cooling device for cooling, and the false twister for false twisting through the yarn feeding device in sequence, and then fed into the protective lower bobbin 1 and upper bobbin 11 for oiling. The yarn body 8 passes through the lower end of the protective lower bobbin 1, the negative ion emitting ring 2, the rotating tube 4, the conical rotating seat 41, the conical oiling cavity 61, and the cylindrical cavity 62 in sequence from bottom to top, and finally passes out from the upper end of the upper bobbin 11 to complete the oiling operation. After the oil solidifies, the yarn body 8 is wound up by the yarn winding device.

[0041] When the yarn body 8 enters the negative ion emitting ring 2, negative ions are generated by the negative ion emitting unit 22 inside the negative ion emitting ring 2, so that the negative ions can act evenly on the yarn body 8, and the yarn body 8 can be charged safely and gently. The yarn body 8 carrying negative ions will quickly pass through the rotating tube 4, the conical rotating seat 41 and enter the conical upper oil chamber 61 and the cylindrical cavity 62. At the same time, the servo motor and the ultrasonic atomizing device are started. The ultrasonic atomizing device inputs oil into multiple oil inlet pipes 7. The oil is sprayed out along the ultrasonic atomizing nozzle 71 and sprayed into the conical upper oil chamber 61. The driving mechanism drives the rotating tube 4 to rotate, which causes the conical rotating seat 41 to drive the spiral blade 42 to rotate. The spiral blade 42 creates an upward spiral airflow in the conical upper oil chamber 61. When the oil mist enters the conical upper oil chamber 61, the spiral airflow drives the oil mist to move upward spirally. When the yarn body 8 carrying negative ions enters the conical oiling chamber 61, the oil mist will continuously wash and wrap the yarn body 8 from all directions and angles with the spiral airflow, so that the yarn body 8 can be evenly contacted with the oil mist. At the same time, because the yarn body 8 carries negative ions, the oil mist can be well adsorbed on the yarn body 8, thus completing the uniform oiling operation.

[0042] When the yarn body 8 is oiled, the remaining oil mist will flow out along the air outlet pipe 63 for recycling and reuse. Meanwhile, some oil mist and oil droplets will adhere to the conical upper oil cavity 61. After the oil collects, it will drip down onto the outer side of the conical seat 3 and the inner side wall of the upper cylinder 11. When the conical rotating seat 41 rotates, it will drive the scraper 5 to rotate synchronously. The scraper 5 scrapes the oil on the outer side of the conical seat 3 and the inner side of the upper cylinder 11, so that the oil enters the annular groove 32. Then, the scraper 5 pushes the oil in the annular groove 32 into the oil outlet pipe 14, thereby discharging the oil for recycling.

A method for preparing a solid-color yarn protective glove according to any one of claims 1-8, characterized in that: The mixture comprises the following raw materials and their weight fractions: 25%–35% high-strength nylon, 25%–35% polyester, 20%–35% polyethylene fiber, 3%–8% carbon fiber bundles, and 3%–8% elastic fiber; the above raw materials are mixed in the specified proportions. Protective glove preparation steps: Step 1: Using polyethylene fiber as the core yarn, the mixed colored matrix fibers are evenly wrapped around the outside of the core yarn through air-jet spinning or Siro spinning to make a mixed-color yarn. This gives the outer layer a soft and hazy mixed-color effect, while the inner layer provides strong protection. The carbon fiber bundles are not exposed, keeping the gloves aesthetically pleasing. Step 2: Immerse the mixed-color yarn in a mixture containing abrasion-resistant agent, waterproof agent, and flame retardant, and squeeze it through rollers. After the impregnation is completed, dry and shape it. Step 3: Based on the 3D model of the hand, develop a weaving program to weave the above-mentioned solid-color yarn into protective gloves. Place the woven protective glove blank onto the hand mold and set it with steam or hot air to obtain a stable and fit hand shape. Step 4: Apply or dip polyurethane, nitrile rubber or latex to the palm area of ​​the protective glove to form a non-slip, wear-resistant and oil-resistant granular or patterned coating, so that the color effect after coating is faintly visible, forming a unique aesthetic. Step 5: Finally, conduct tests on protective properties such as abrasion resistance and antistatic properties. After the tests are completed, package and store the qualified protective gloves.
