Description

Technical Field

[0001] This invention relates to the field of antibacterial bandage production technology, and in particular to a method for preparing an antibacterial polyester bandage and its fine yarn preparation device. Background Technology

[0002] Medical bandages are a common medical product, mainly used to bandage and fix wounds, injured areas, or post-operative areas, to isolate external bacteria, dust, and other contaminants, reduce the risk of wound infection, and create a relatively clean environment for wound healing.

[0003] At the same time, bandages can also hold the medications, gauze and other dressings applied to the wound in place, preventing them from shifting or falling off, and ensuring that the dressings can continue to function.

[0004] Based on the above, the inventor believes that traditional bandages still have problems such as insufficient antibacterial properties, poor breathability and low comfort. Furthermore, during the bandage manufacturing process, when the spinning machine spins at high speed, the traditional steel ring and the steel traveler rub against each other at high speed, which often generates high temperature, causing heat damage to the yarn, resulting in yellowing and reduced strength, and accelerating the wear and tear of the steel ring.

[0005] In view of this, the inventors have proposed a method for preparing an antibacterial polyester bandage and a fine yarn device thereof. Summary of the Invention

[0033] The spinning machine is equipped with a yarn guiding assembly and a mounting plate. A steel ring is mounted on the mounting plate, and a cooling assembly is located on the steel ring to automatically cool the steel ring during operation.

[0034] The mounting plate has a groove, and the cooling component includes a mounting base fixed in the groove, a cooling component and a guide installed on the mounting base and the steel ring respectively. The automatic cooling of the steel ring is achieved through the cooperation of the cooling component and the guide.

[0035] A further feature of the present invention is that the guide member includes two guide rings symmetrically disposed on the periphery of the steel collar.

[0036] By adopting the above technical solution, it is convenient to load and unload the guide ring.

[0037] A further configuration of the present invention is as follows: the guide ring includes an inlet pipe, a bent pipe fixed to the end of the inlet pipe away from the cooling assembly, and a side ring integrally fixed with the bent pipe, the outer side of the side ring being fixed to the mounting plate by a support foot.

[0038] By adopting the above technical solution, a cooling track is formed that allows the cooling balls to roll.

[0039] A further configuration of the present invention is as follows: the cooling assembly includes a protective cover fixed at its bottom end to a mounting base, a cooling ball, a docking assembly for mounting the cooling ball, and an acceleration assembly and an output component disposed within the protective cover; the mounting base is provided with an oil storage assembly for exchanging heat with the cooling ball.

[0040] By adopting the above technical solution, the cooling ball can roll along the outer side of the steel ring to achieve a contact heat exchange effect.

[0041] A further embodiment of the present invention is that the docking assembly includes a docking compartment whose bottom is fixed to the mounting base, a guide rail opened in the docking compartment, and a slot opened below the guide rail. The docking compartment is connected to the inlet pipe through an upwardly inclined connecting pipe, and the guide rail and the slot are connected through a strip-shaped opening.

[0042] By adopting the above technical solution, the bottom part of the cooling ball is submerged in the strip-shaped opening.

[0043] A further configuration of the present invention is as follows: the cooling ball slides along the inner wall of the guide rail, the acceleration assembly includes a magnet column coaxially arranged with the cooling ball, the outer side of the magnet column is fixed to the mounting base by a mounting bracket, and the magnet column and the cooling ball are connected by the acceleration ball.

[0044] By adopting the above technical solution, the acceleration ball and the cooling ball remain coaxial.

[0045] A further configuration of the present invention is as follows: the output component includes an impact block that abuts against the side of the magnet column away from the acceleration ball, a guide plate fixedly connected to the outside of the impact block, an electromagnetic chuck fixed on the mounting base, and a spring for providing a reset force to the guide plate.

[0046] By adopting the above technical solution, the two ends of the spring are fixedly connected to the guide plate and the bracket, respectively.

[0047] A further configuration of the present invention is that the cooling ball includes a spherical outer shell, a heat exchange fluid filled in the spherical outer shell, and a heat exchange groove formed on the inner wall of the spherical outer shell.

[0048] By adopting the above technical solutions, the contact area of ​​the heat exchange fluid can be increased.

[0049] A further feature of the present invention is that the mounting base has an internal mounting groove, and the oil storage assembly includes an oil storage tank fixed in the mounting groove and heat transfer oil filled in the oil storage tank, with the oil outlet end of the oil storage tank being inserted into the slot.

[0050] The above technical solution is used to store heat transfer oil.

[0051] The beneficial effects of this invention are:

[0052] 1. Through the triple synergistic antibacterial mechanism of bamboo fiber, silver ion fiber and nano silver, it achieves natural antibacterial, long-lasting antibacterial and instantaneous bactericidal effects, reduces the risk of drug resistance, covers a wide range of pathogens, and the proportion of bamboo fiber is ≥20%, which improves moisture absorption through its natural porous structure. At the same time, the combination of silver ion fiber and polyester fiber optimizes mechanical strength and balances breathability and durability, so as to reduce the poor breathability of synthetic fiber-based bandages, which can easily lead to damp wounds and delayed healing.

[0053] 2. After the steel ring and steel wire ring heat up at high speed, the temperature of the steel ring is detected in real time by the temperature sensor, and the cooling component is activated according to the set threshold. This allows the cooling ball to quickly come into contact with the steel ring and absorb heat. The temperature of the cooling ball is reduced by the heat transfer oil in the docking chamber. This process is repeated to automatically reduce the operating temperature of the steel ring, thereby reducing the impact of high temperature on the bandage yarn and steel ring.

[0054] 3. The cooling balls are driven by a permanent magnet chain acceleration method, which can quickly complete the heat exchange operation along the steel ring. At the same time, the steel ring is coated with heat-conducting oil to improve the convenience of heat exchange between the cooling balls and the steel ring. It can also significantly reduce friction to reduce the negative effects of frictional heat generation, so that the steel ring can be automatically and timely cooled to reduce the negative effects of high temperature.

[0055] 4. The cooling ball is filled with heat exchange fluid, which can make large contact with the ball for heat exchange when the ball rolls. After the ball enters the docking chamber, the heat exchange fluid will come into contact with the heat transfer oil by its own weight to exchange heat, so as to transfer the surface temperature of the ball to the heat transfer oil for cooling and improve the cooling effect of the cooling ball.

[0096] This invention specifically provides a yarn device for an antibacterial polyester bandage; please refer to [reference needed]. Figures 1-9 The spinning device includes a spinning machine 1 and a cooling component 2.

[0097] The spinning machine 1 is equipped with a yarn guiding assembly 11 and a mounting plate 12. A ring 13 is mounted on the mounting plate 12. A cooling assembly 2 is located on the ring 13 to automatically cool the ring 13 during operation. A traveler 14 is provided on the ring 13. During spinning, the traveler 14 rotates around the upper part of the ring 13, thereby gradually generating heat in the ring 13. Since the above-mentioned components are all based on existing technology, their connection structure and usage will not be described in detail here.

[0098] Specifically, the mounting plate 12 has grooves 15, the number and position of which match the ring 13. The cooling component 2 includes a mounting base 3 fixed in the groove 15, a cooling component 4 and a guide 5 respectively mounted on the mounting base 3 and the ring 13. The ring 13 is automatically cooled by the cooperation of the cooling component 4 and the guide 5. The bottom surface of the ring 13 is provided with a temperature sensor 131 for detecting the temperature. The temperature sensor 131 is embedded in the mounting plate 12 to monitor the temperature of the ring 13 in real time and transmit it to the controller of the spinning machine 1 for processing.

[0099] In practice, the guide 5 includes two guide rings 51 symmetrically arranged around the steel collar 13. The guide rings 51 are detachably connected to the surface of the mounting plate 12. The guide rings 51 are made of heat-absorbing metal.

[0100] The guide ring 51 includes an inlet pipe 511, a bent pipe 512 fixed to the end of the inlet pipe 511 away from the cooling component 4, and a side ring 513 integrally fixed with the bent pipe 512. The outer side of the side ring 513 is fixed to the mounting plate 12 by a support foot 514. The support foot 514 is fixedly connected to the outer side of the side ring 513. The side ring 513 is coaxially arranged with the steel ring 13.

[0101] By adopting the above technical solution, the two guide rings 51 can be detachably connected to the mounting plate 12 through the support foot 514, which facilitates installation on the outside of the steel ring 13 and replacement. The side ring 513 cooperates with the outside of the steel ring 13 to form a cooling track for the cooling ball 42 to roll, so as to absorb the heat on the steel ring 13 and cool the steel ring 13. The top of the cooling ball 42 is spaced apart from the wire ring 14 to avoid contact between the two.

[0102] During implementation, both the steel ring 13 and the guide ring 51 are coated with heat-conducting oil, which can reduce the contact friction with the cooling ball 42 to reduce frictional heating, and also facilitate the cooling ball 42 to increase its thermal conductivity when rolling, so as to meet the cooling needs of the steel ring 13.

[0103] Furthermore, the cooling assembly 4 includes a protective cover 41 fixed at the bottom end on the mounting base 3, a cooling ball 42, a docking assembly for mounting the cooling ball 42, and an acceleration assembly and an output component disposed within the protective cover 41. The mounting base 3 is provided with an oil storage assembly 7 for exchanging heat with the cooling ball 42.

[0104] It is worth noting that each mounting base 3 is provided with two cooling components 4, and there is one cooling ball 42, which is located on one of the cooling components 4. Through the action of the acceleration component and the output component, the cooling ball 42 can roll along the outside of the steel ring 13 to achieve the contact heat exchange effect, and then enter the other cooling component 4, and reset in the same way. This process is repeated to continuously absorb the heat on the steel ring 13.

[0105] Specifically, the docking assembly includes a docking compartment 431 whose bottom is fixed to the mounting base 3, a guide rail 432 opened in the docking compartment 431, and a slot 433 opened below the guide rail 432. The docking compartment 431 is connected to the inlet pipe 511 through an upwardly inclined connecting pipe 6.

[0106] The bottom end of the connecting pipe 6 is fixedly connected to the guide rail 432, and the top end is fixedly connected to the inlet pipe 511, so that the connecting pipe 6, the guide rail 432 and the inner wall of the inlet pipe 511 can form a sealed channel for the cooling ball 42 to roll.

[0107] When the cooling ball 42 is subjected to force and rolls outward along the guide rail 432, it will enter the inlet pipe 511 along the connecting pipe 6. Guided by the bend pipe 512 and the side ring 513, the cooling ball 42 can be smoothly sent into the docking chamber 431 on another cooling component 4. During the process, the bottom edge of the cooling ball 42 rolls along the base of the steel ring 13 and the outer wall of the cooling ball 42 contacts the side wall of the steel ring 13, thereby completing the heat transfer and meeting the cooling requirements.

[0108] The guide rail 432 and the slot 433 are connected by a strip opening 434, and the bottom part of the cooling ball 42 is submerged in the strip opening 434.

[0109] The cooling ball 42 slides along the inner wall of the guide rail 432, which is a cylindrical groove. The outer side of the cooling ball 42 is in contact with the inner wall of the guide rail 432. The entire docking chamber 431 is made of thermally conductive metal to facilitate heat exchange for the cooling ball 42 after it absorbs heat, thereby facilitating the cooling of the cooling ball 42 to meet the cooling requirements of the steel ring 13.

[0110] In implementation, the acceleration assembly includes a magnet post 441 coaxially arranged with the cooling ball 42. The magnet post 441 is fixed to the mounting base 3 via a mounting bracket 442. The magnet post 441 and the cooling ball 42 are connected by an acceleration ball 443, which is fixed on the mounting base 3. The overall size of the acceleration ball 443 is the same as that of the cooling ball 42, and the magnet post 441, acceleration ball 443 and cooling ball 42 are coaxial. Both the acceleration ball 443 and the cooling ball are steel balls.

[0111] The docking chamber 431 has an opening 435 on the side near the magnet column 441, and the outer side of the cooling ball 42 is magnetically attracted to the magnet column 441 through the opening 435.

[0112] By adopting the above technology, the principle of permanent magnet chain acceleration is satisfied, and a closed magnetic circuit of "steel ball-magnet-steel ball" can be formed at both ends of the magnet column 441. When the outer side of the acceleration ball 443 is hit by the output component, the magnetic circuit is broken instantly, and the magnetic field energy is converted into the kinetic energy of the cooling ball 42, causing it to pop out at high speed, so that the cooling ball 42 can meet the kinetic energy requirements for rapid rolling on the steel collar 13.

[0113] Specifically, a mounting cover 457 is fixed on the mounting base 3, and the output component is located inside the mounting cover 457. The output component includes an impact block 451 that abuts against the side of the magnet post 441 away from the acceleration ball 443, a guide plate 452 fixedly connected to the outside of the impact block 451, an electromagnetic chuck 453 fixed on the mounting base 3, and a spring 454 for providing a reset force for the guide plate 452. The guide plate 452 is slidably mounted on the guide rod 455, and the guide rod 455 is fixedly perpendicular to the mounting base 3. A bracket 456 is fixed on the side of the mounting base 3 near the electromagnetic chuck 453, and the two ends of the spring 454 are fixedly connected to the guide plate 452 and the bracket 456, respectively.

[0114] By employing the aforementioned technology, when the electromagnetic chuck 453 is energized, it can apply a magnetic attraction force to the guide plate 452 made of magnetic material, causing the guide plate 452 to drive the impact block 451 away from the acceleration ball 443. Then, the electromagnetic chuck 453 is de-energized, causing the impact block 451 to strike the acceleration ball 443 through the elastic force of the spring 454, thereby causing the cooling ball 42 on the other side to accelerate out. This causes the oil-coated cooling ball 42 to rotate rapidly on the inclined connecting pipe 6, throwing most of the heat transfer oil 72 into the connecting pipe 6, allowing the heat transfer oil 72 to flow naturally to the bottom of the connecting pipe 6. Meanwhile, the cooling ball 42 with a thin layer of oil on its surface can quickly come into contact with the steel collar 13 for heat exchange.

[0115] Furthermore, the cooling ball 42 includes a spherical outer shell 421, a heat exchange fluid 422 filled in the spherical outer shell 421, and a heat exchange groove 423 formed on the inner wall of the spherical outer shell 421. The heat exchange groove 423 is provided to increase the contact area with the heat exchange fluid 422.

[0116] By employing the above-mentioned technology, the spherical outer shell 421 is made of steel and has magnetic attraction and thermal conductivity. The heat exchange fluid 422 is made of gallium-indium alloy with a melting point of 15°C. After the spherical outer shell 421 absorbs heat, it reaches its melting point and melts into a liquid state. As the spherical outer shell 421 rolls, the heat exchange fluid 422 can frequently contact different inner walls of the spherical outer shell 421, improving the heat exchange effect. When the spherical outer shell 421 is stationary, the heat exchange fluid 422 can accumulate at the bottom of the spherical outer shell 421, facilitating contact and heat exchange with the oil storage component 7 and improving the cooling rate.

[0117] Furthermore, the mounting base 3 has an internal mounting groove 31. The oil storage assembly 7 includes an oil storage tank 71 fixed in the mounting groove 31 and heat transfer oil 72 filled in the oil storage tank 71. The oil outlet end of the oil storage tank 71 is inserted into the slot 433. The oil storage tank 71 has a straight hook structure. The horizontal compartment at its bottom is used to connect the inner and outer vertical compartments. The height of the inner vertical compartment is lower than that of the outer vertical compartment, and the top of the inner vertical compartment is inserted into the inner wall of the slot 433.

[0118] During implementation, due to the height difference, the liquid level of the heat transfer oil 72 will extend to the bottom of the slot 433, the strip-shaped opening 434 above it, and the connecting pipe 6. The heat transfer oil 72 in the outer vertical chamber with a higher liquid level can be automatically replenished when there is heat loss in the internal vertical chamber until the heat transfer oil 72 in the two vertical chambers is at the same height. The top of the outer vertical chamber is equipped with a screw cap 73, which can replenish the heat transfer oil 72 by opening and closing the screw cap 73, so that the heat transfer oil 72 does not need to be filled manually frequently.

[0119] This allows the cooling ball 42 to come into contact with the heat transfer oil 72 for heat exchange after rolling into the docking chamber 431. In other words, the cooling ball 42, after absorbing the heat of the steel ring 13, can roll into the docking chamber 431 to come into contact with the heat transfer oil 72 for cooling. Alternatively, the surface of the cooling ball 42 can be coated with the heat transfer oil 72 so that the cooling ball 42 can automatically coat the surface of the steel ring 13 with the heat transfer oil 72 during rolling to achieve automatic lubrication and cooling.

[0120] The docking chamber 431 is made entirely of thermally conductive metal, so it can also help transfer heat to the thermally conductive oil 72 after contacting the cooling ball 42, thus achieving the purpose of auxiliary cooling.

[0121] During implementation, when the temperature sensor 131 detects that the temperature of the steel ring 13 is too high, such as greater than 100°C, the cooling component 4 can be activated. Through the cooperation of the two cooling components 4, the cooling ball 42 can reciprocate and contact the outside of the steel ring 13 to exchange heat, thereby reducing the operating temperature of the steel ring 13. It can also realize the automatic lubrication and application of heat transfer oil 72 to the contact surface between the steel ring 13 and the cooling ball 42, eliminating the need for frequent manual application of heat transfer oil 72, which helps to save manpower and improve the automation process of the equipment.
