Description

Technical Field

[0001] This utility model belongs to the technical field of rewinding machines, and in particular relates to a novel heating and drying device for rewinding machines. Background Technology

[0002] Rewinding machines, as core equipment in the textile, cable, and chemical fiber industries, are mainly used to rewind and reseal the yarn formed during the production process to meet the requirements of subsequent processing for yarn package specifications and tension consistency. Drying the yarn is a crucial step in the rewinding machine's workflow, as the surface of the yarn is easily affected by environmental moisture or residual water stains from the process during the initial forming, cleaning, or storage stages.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: most existing heating rollers use a single fixed temperature (usually set to high temperature to meet rapid drying requirements). When wet yarn comes into direct contact with the high-temperature roller, the surface moisture evaporates rapidly and instantly, causing a sudden rise in the local temperature of the yarn. For synthetic fibers, this instantaneous high temperature can easily cause the fibers to soften, melt, or even break; for natural fibers, it may cause the fiber structure to shrink and deform, damaging the physical and mechanical properties of the yarn, ultimately leading to a decline in product quality and a significant increase in the defect rate.

[0004] Because the water stains adhering to the surface of the silk thread require a lot of heat to evaporate, this not only prolongs the drying time but also causes the electric heating tube to operate under high load for a long time, resulting in a significant increase in energy consumption.

[0005] Therefore, we propose a novel heating and drying device for rewinding machines, which can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a novel heating and drying device for rewinding machines, which can achieve gradient heating protection and water stain pretreatment.

[0007] In view of this, the present invention provides a novel heating and drying device for a rewinding machine, comprising a heating frame and a wire to be heated. The heating frame is provided with a conveying mechanism on its inner side for tensioning and conveying the wire. The conveying mechanism is provided with a heating component inside for gradually heating the wire during the conveying process. The bottom of the inner side of the heating frame is provided with a squeezing mechanism for scraping off water stains on the outside of the wire.

[0008] Furthermore, the conveying mechanism includes a medium-temperature roller rotatably connected to the middle of the upper part of the inner side of the heating frame, and a preheating roller and a high-temperature roller disposed on the lower ends of both sides of the medium-temperature roller. Connecting pipes are fixedly installed at both ends of the medium-temperature roller, the preheating roller and the high-temperature roller. Drive motors are fixedly connected to the front and rear sides of the heating frame. The connecting pipes at one end of the medium-temperature roller, the preheating roller and the high-temperature roller are fixedly connected to the corresponding drive motor shaft ends on the outer side of the heating frame.

[0009] Furthermore, the outer sides of the medium-temperature roller, preheating roller, and high-temperature roller are provided with annular wire grooves at equal intervals, and the wires are slidably connected to the wire grooves.

[0010] Furthermore, the heating assembly includes a heating groove horizontally opened in the middle of the medium-temperature roller, the preheating roller, and the high-temperature roller; a hot oil pipe for providing high-temperature hot oil; and an oil guide groove for conveying hot oil. The two ends of the heating groove are connected to the connecting pipe. The heating frame has symmetrical connecting grooves on its front and rear sides. The end of the connecting pipe away from the drive motor is rotatably connected to the connecting groove through a sealed bearing. The outer side of the connecting pipe near the drive motor has a through opening. The side of the connecting pipe near the drive motor is connected to the connecting groove through the through opening. Adjacent sets of the connecting grooves are connected through the oil guide groove.

[0011] Furthermore, the oil outlet end of the hot oil pipe is connected to the connecting groove at one end of the high-temperature roller, and the connecting groove at one end of the preheating roller is connected to an oil drain pipe.

[0012] Furthermore, the extrusion mechanism includes a pressure block for extruding the outer yarn of the preheating roller, and a spring for providing thrust to the pressure block. A support plate is horizontally fixedly installed at the lower end of the preheating roller, and the spring is placed between the pressure plate and the support plate.

[0013] Furthermore, the pressure blocks are equidistantly installed on the upper surface of the pressure plate, and the pressure blocks correspond to the wire grooves on the outside of the preheating roller.

[0014] Furthermore, limit rods are fixedly installed at both ends of the bottom side of the pressure plate, the limit rods penetrate the support plate and are slidably connected to the support plate, and the springs are sleeved on the outside of the limit rods.

[0015] The beneficial effects of this utility model are:

[0016] 1. The conveying mechanism inside the heating rack provides a stable transmission path for the yarn, ensuring that the yarn remains taut throughout the conveying process and preventing uneven heating or positional shifts due to yarn slack. The heating components inside the conveying mechanism gradually heat the yarn as it moves, preventing damage to the yarn material from instantaneous high temperatures and achieving efficient drying. The squeezing mechanism at the bottom of the inner side of the heating rack actively acts on the yarn surface before it enters the heating stage, scraping off any water stains adhering to the outside of the yarn. The friction between the squeezing mechanism and the yarn generates a small amount of heat, which can preheat the yarn. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 4 A novel heating and drying device for a rewinding machine includes a heating frame 1 and a wire 15 to be heated. The heating frame 1 has a conveying mechanism on its inner side for tensioning and conveying the wire 15. The conveying mechanism has a heating component inside for gradually heating the wire 15 during the conveying process. The bottom of the inner side of the heating frame 1 has a squeezing mechanism for scraping off water stains on the outside of the wire 15.

[0025] The conveying mechanism inside the heating rack 1 provides a stable transmission path for the wire 15, ensuring that the wire 15 remains taut during the conveying process and avoiding uneven heating or positional shift due to slack in the wire 15. The heating component inside the conveying mechanism gradually heats the wire 15 as it moves with the conveying mechanism, preventing damage to the wire 15 material due to instantaneous high temperature and achieving efficient drying. The squeezing mechanism at the bottom of the inner side of the heating rack 1 actively acts on the surface of the wire 15 before it enters the heating stage, scraping off the water stains attached to the outside of the wire 15 in advance. The friction between the squeezing mechanism and the wire 15 generates a small amount of heat, which can preheat the wire 15.

[0026] Furthermore, the conveying mechanism includes a medium-temperature roller 12 rotatably connected to the middle of the upper part of the inner side of the heating frame 1, and a preheating roller 11 and a high-temperature roller 13 disposed at the lower ends of both sides of the medium-temperature roller 12. Connecting pipes 16 are fixedly installed at both ends of the medium-temperature roller 12, the preheating roller 11 and the high-temperature roller 13. Drive motors 17 are fixedly connected to the front and rear sides of the heating frame 1. The connecting pipes 16 at one end of the medium-temperature roller 12, the preheating roller 11 and the high-temperature roller 13 are fixedly connected to the shaft end of the drive motor 17 corresponding to the outer side of the heating frame 1.

[0027] When the drive motor 17 starts, it drives the medium-temperature roller 12, the preheating roller 11, and the high-temperature roller 13 to rotate synchronously through the connecting pipe 16. Under the traction of the three sets of rollers, the wire 15 moves along the path of the preheating roller 11, the medium-temperature roller 12, and the high-temperature roller 13. The triangular layout, combined with the synchronous rotation of the rollers, can ensure the tension of the wire 15 during the conveying process and provide sufficient contact time for subsequent gradient heating.

[0028] Furthermore, the outer sides of the medium-temperature roller 12, the preheating roller 11 and the high-temperature roller 13 are provided with annular wire grooves 14 at equal intervals, and the wire 15 is slidably connected to the wire grooves 14.

[0029] The wire groove 14 can limit the wire 15, preventing multiple wires 15 from getting tangled or shifting during conveying or heating. After the wire 15 is embedded in the wire groove 14, it will make uniform contact with the roller surface, avoiding uneven heating due to insufficient contact between the wire 15 and the roller.

[0030] Furthermore, the heating assembly includes a heating groove 2 horizontally opened in the middle of the medium-temperature roller 12, the preheating roller 11 and the high-temperature roller 13, a hot oil pipe 22 for providing high-temperature hot oil, and an oil guide groove 25 for conveying hot oil. The two ends of the heating groove 2 are connected to the connecting pipe 16. The heating frame 1 has symmetrical connecting grooves 21 on the front and rear sides. The end of the connecting pipe 16 away from the drive motor 17 is rotatably connected to the connecting groove 21 through a sealed bearing. The outer side of the connecting pipe 16 near the drive motor 17 has a through opening 24. The side of the connecting pipe 16 near the drive motor 17 is connected to the connecting groove 21 through the through opening 24. Two adjacent sets of connecting grooves 21 are connected through the oil guide groove 25.

[0031] After hot oil enters the connecting groove 21 corresponding to the high-temperature roller 13 from the hot oil pipe 22, it first flows through the heating groove 2 in the middle of the high-temperature roller 13, where the hot oil temperature is at its highest, allowing for high-temperature heating of the yarn 15 in contact with the high-temperature roller 13. Subsequently, the hot oil flows into the connecting groove 21 of the medium-temperature roller 12 via the oil guide groove 25. After the initial heat transfer, the oil temperature decreases, and the yarn 15 is then heated at a medium temperature through the heating groove 2 in the middle of the medium-temperature roller 12. Finally, the hot oil flows into the connecting groove 21 corresponding to the preheating roller 11, where the oil temperature further decreases, and the yarn 15 is preheated through the heating groove 2 in the middle of the preheating roller 11 before finally being discharged from the oil drain pipe 23. Throughout the process, the hot oil temperature gradually increases along the direction of the preheating roller 11, the medium-temperature roller 12, and the high-temperature roller 13, and the corresponding roller body temperature also increases gradually, thus achieving a gradual temperature rise in the yarn 15 during the heating process and avoiding damage to the yarn 15 from instantaneous high temperatures.

[0032] Furthermore, the oil outlet end of the hot oil pipe 22 is connected to the connecting groove 21 at one end of the high temperature roller 13, and the connecting groove 21 at one end of the preheating roller 11 is connected to the oil drain pipe 23.

[0033] After the hot oil completes its final heat transfer in the preheating roller 11, the oil temperature drops to its lowest point. Then, it is discharged from the oil drain pipe 23 connected to the corresponding connecting groove 21 of the preheating roller 11, thus realizing the recycling of hot oil.

[0034] Furthermore, the extrusion mechanism includes a pressure block 31 for extruding the outer wire 15 of the preheating roller 11, and a spring 33 for providing thrust to the pressure block 31. A support plate 32 is horizontally fixedly installed at the lower end of the preheating roller 11, and the spring 33 is placed between the pressure plate 3 and the support plate 32.

[0035] The spring 33 can push the pressure block 31 on the upper surface of the pressure plate 3 to move upward, so that the pressure block 31 presses against the surface of the filament 15 on the outside of the preheating roller 11. On the one hand, the contact between the pressure block 31 and the filament 15 can scrape off the water stains attached to the surface of the filament 15, reducing the moisture evaporation load in the subsequent heating process. On the other hand, the friction between the pressure block 31 and the filament 15 will generate a small amount of heat, which can preheat the filament 15 and help improve the drying efficiency.

[0036] Furthermore, the pressure blocks 31 are equidistantly installed on the upper surface of the pressure plate 3, and the pressure blocks 31 correspond to the wire groove 14 on the outer side of the preheating roller 11.

[0037] Since the wire 15 is embedded in the wire groove 14 of the preheating roller 11, the pressure block 31, which is provided corresponding to the wire groove 14, can be embedded in the wire groove 14 and contact the wire 15, thus avoiding the pressure block 31 from being unable to act on the wire 15 due to positional displacement.

[0038] Furthermore, limit rods 34 are fixedly installed at the front and rear ends of the bottom side of the pressure plate 3. The limit rods 34 pass through the support plate 32 and are slidably connected to the support plate 32. The spring 33 is sleeved on the outside of the limit rods 34.

[0039] The limiting rod 34 can guide the up and down movement of the pressure plate 3, preventing the spring 33 from causing the pressure plate 3 to shift back and forth or left and right during the extension and retraction process, and ensuring that the pressure block 31 corresponds to the guide groove 14 of the preheating roller 11.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
