Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, and in particular to a yarn waxing device. Background Technology

[0002] Yarn waxing involves evenly applying a thin layer of wax to the surface of yarn (especially warp yarns). This is mainly done before warping or weaving processes to improve the yarn's weaveability and ensure smooth subsequent production. The wax helps loose fibers on the yarn surface adhere tightly to the main body, making the yarn smoother and more compact.

[0003] The currently widely used "friction waxing method" mainly relies on direct contact between the yarn and the solid wax block. This method results in uneven contact pressure, causing the wax to adhere mechanically and irregularly to the surface of the yarn. The wax coverage is uneven, and the wax block is consumed quickly, requiring frequent machine shutdowns for replacement.

[0004] Therefore, we propose a yarn waxing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yarn waxing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A yarn waxing device, comprising: The housing has an open top for the entry and exit of lines, and at least three first guide rollers arranged in an inverted triangle are rotatably connected between the inner walls of the two sides of the housing. The L-shaped mounting plate is fixed to the top of the housing. The corners of the mounting plate are arc-shaped and multiple lead wire holes are opened through the bottom. An arc-shaped tube is installed on one side of the mounting plate. A clearance opening is provided on the side of the arc-shaped tube closest to the mounting plate. A fan is fixed on the surface of the mounting plate. The air outlet of the fan is connected to the arc-shaped tube through a flexible hose. At least two wire clamping mechanisms are located inside the housing and are used in conjunction with two first guide rollers, respectively; The yarn guide mechanism, located at the top of the mounting plate, is used to guide the movement of the yarn. The positioning mechanism, located on one side of the mounting plate, is used to position the arc-shaped tube.

[0007] In one possible design, the wire clamping mechanism includes fixed frames respectively fixed to the inner walls of both sides of the housing, a U-shaped slide plate slidably connected between the two fixed frames, a second guide roller rotatably connected between the inner walls of both sides of the slide plate, the second guide roller cooperating with the first guide roller, and a spring fixed between one side of the slide plate and one side of the inner wall of the fixed frame via a spring seat.

[0008] In one possible design, the lead wire mechanism includes a top seat fixed to the top of the mounting plate, with two third guide rollers rotatably passing between the inner walls of the two sides of the top seat. Gears are fixed to the outer walls of the third guide rollers, and the two gears mesh with each other. A motor and a shield are fixed to one outer wall of the top seat, with the gears and the motor located inside the shield. The output shaft of the motor is coaxially fixed to one of the third guide rollers.

[0009] In one possible design, the positioning mechanism includes two positioning plates fixed to one side of the arc-shaped tube and a positioning plate detachably mounted on one side of the mounting plate. The positioning plate has multiple positioning grooves on one side, with the arc-shaped tube located in one of the positioning grooves. Two through holes are opened through one side of the positioning plate, and bolts and screws are threaded through the through holes to connect with the mounting plate.

[0010] In one possible design, the outer walls of the first guide roller, the second guide roller, and the third guide roller are each provided with multiple annular grooves of different sizes.

[0011] In one possible design, a sealing strip is fixed to one side of the clearance opening.

[0012] In one possible design, the bottom end of the lead hole is provided with a guide surface.

[0013] In one possible design, a base is fixed to the bottom of the housing, a plurality of heating tubes are fixed to the inner wall of the bottom of the base, and a temperature sensor is fixed to the inner wall of the housing.

[0014] In this application, during use, the sliding plate is moved to separate the second guide roller and the first guide roller. The yarn is then passed through the gap between them and a suitable annular groove is selected. After releasing the sliding plate, a spring pushes the sliding plate back to its original position, causing the first and second guide rollers to clamp and guide the yarn, ensuring yarn tension and compression of the wax. The yarn is then passed through the lead-in hole, and the motor is started to drive the third guide roller to rotate, facilitating yarn passage. After the yarn has passed through, the motor is temporarily turned off. The final yarn installation effect is as follows: Figure 1 As shown, the arc-shaped tube is then attached to the mounting plate, so that the yarn is located inside the arc-shaped tube. Then, the positioning plate is fixed with bolts, so that the arc-shaped tube is located in the corresponding positioning groove. The positioning pieces are located at the upper and lower ends of the positioning plate, thus completing the positioning of the arc-shaped tube. Then, the wax block is placed into the housing, and the heating tube is turned on to heat the wax block until it melts. Then, the motor is turned on, and the motor drives the third guide roller to rotate, thereby guiding the yarn to move. After the yarn passes through the liquid wax, it is squeezed by the first guide roller and the second guide roller to squeeze off the excess liquid wax. Then, the yarn passes through the lead hole and the arc-shaped tube. At the same time, the fan is turned on to guide the airflow through the arc-shaped tube. Under the guidance of the arc-shaped tube, the airflow rapidly cools the wax on the yarn.

[0015] Beneficial effects: In this utility model, the yarn waxing device can guide the yarn through the liquid wax by setting the first guide roller, the shell and other structures, so that the wax coverage is more uniform and the yarn of different thicknesses can be processed. In this utility model, the yarn waxing device, through the setting of the yarn clamping mechanism and other structures, can clamp and squeeze the yarn with liquid wax attached, which not only ensures the yarn is taut, but also squeezes the wax on the yarn to avoid excessive wax coverage affecting subsequent use. In this utility model, the yarn waxing device, through the setting of structures such as an arc tube and a fan, can quickly cool the wax on the yarn, and the position of the arc tube can be adjusted according to the thickness of the yarn.

[0018] 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.

[0019] In one embodiment: Refer to Figures 1-4 A waxing device includes a housing 1, the top of which is open for thread entry and exit. The housing 1 serves as the main frame of the device, and three first guide rollers 3 are rotatably connected between the inner walls on both sides. The three first guide rollers 3 are arranged in an inverted triangle. This arrangement allows the yarn to form a reasonable movement path within the housing, ensuring that the yarn has sufficient length to contact the liquid wax.

[0020] A base 4 is fixedly installed at the bottom of the housing 1. Multiple heating tubes 5 are fixedly installed on the inner wall of the bottom of the base 4. The heating tubes 5 are evenly distributed at the bottom of the base 4. After starting, they can evenly heat the wax block placed in the housing 1 to avoid insufficient melting of local wax blocks.

[0021] A temperature sensor is also fixed to the inner wall of the housing 1. The temperature sensor can monitor the temperature inside the housing 1 in real time to prevent the wax from deteriorating due to excessive temperature or solidifying due to excessive temperature, and ensure that the waxing process is stable. Specifically, the temperature sensor is electrically connected to the controller. When the temperature exceeds the set range, the controller will automatically adjust the start and stop of the heating tube to maintain the wax liquid in the optimal working temperature range, thereby ensuring that the yarn can evenly absorb an appropriate amount of wax liquid during the waxing process. An L-shaped mounting plate 2 is fixed to the top of the housing 1. The corners of the mounting plate 2 are arc-shaped, which helps to guide airflow in conjunction with the arc-shaped tube 15. Multiple thread guide holes 19 are evenly distributed along the width of the mounting plate 2 at the bottom. These multiple thread guide holes 19 can correspond to different yarn processing paths. A guide surface 20 is provided at the bottom of each thread guide hole 19. When the yarn passes through the thread guide hole 19, the guide surface 20 guides the yarn smoothly into the hole, providing convenience for workers. Specifically, the guide surface 20 is an inclined arc-shaped structure, which effectively reduces frictional resistance during yarn threading and forms a flared interface located in the direction the yarn comes from. The wire clamping mechanism is located inside the housing 1 and is used in conjunction with two first guide rollers 3. Each wire clamping mechanism includes a fixed frame 6, a sliding plate 7, a second guide roller 8, and a spring 9.

[0022] Fixed frames 6 are respectively fixed to the inner walls of both sides of the housing 1. A U-shaped sliding plate 7 is slidably connected between the two fixed frames 6. The sliding plate 7 can slide back and forth along the inner wall of the fixed frame 6. A second guide roller 8 is rotatably connected between the inner walls of the two sides of the sliding plate 7. The position of the second guide roller 8 is opposite to the corresponding first guide roller 3. The two cooperate to clamp the yarn.

[0023] For example, in this embodiment, the fixed frame 6 is set as a rectangular frame with a rectangular groove structure on its inner wall. The two ends of the slide plate 7 are embedded in the groove and can slide freely along its length to ensure smooth operation without deviation.

[0024] A spring 9 is fixed between one side of the skateboard 7 and the inner wall of one side of the fixed frame 6 via a spring seat. The spring seat can stably fix the spring 9 and prevent the spring 9 from shifting during the extension and retraction process.

[0025] For example, the spring 9 is located at one end of the fixed frame 6 away from the first guide roller 3. One end of the spring 9 abuts against the inner wall of the fixed frame 6, and the other end abuts against the side end face of the slide plate 7. The spring 9 pushes the slide plate 7 to move closer to the first guide roller 3, so that the second guide roller 8 and the corresponding first guide roller 3 form an elastic clamping structure. When the yarn passes through, the clamping force can be automatically adjusted to adapt to yarns of different thicknesses, while avoiding damage to the yarn surface due to excessive pressure.

[0026] In use, manually push the slide plate 7 to move it away from the first guide roller 3. At this time, the spring 9 is compressed, and the second guide roller 8 separates from the first guide roller 3, forming a gap for the yarn to pass through. Select annular grooves of matching size on the outer walls of the first guide roller 3 and the second guide roller 8 according to the thickness of the yarn to be processed. The outer walls of the first guide roller 3, the second guide roller 8, and the subsequent third guide roller 11 all have multiple annular grooves of different sizes. Different sized annular grooves can accommodate yarns of different thicknesses, preventing the yarn from shifting during movement and ensuring that the yarn always moves along a fixed path. Pass the yarn through the gap between the second guide roller 8 and the first guide roller 3, and position the yarn within the selected annular groove. Then release the slide plate 7. The spring 9, under the action of elastic restoring force, pushes the slide plate 7 back to its original position, causing the second guide roller 8 to move closer to the first guide roller 3 until the two clamp the yarn together.

[0027] This clamping method not only ensures that the yarn remains taut during the waxing process, preventing uneven wax layer caused by yarn slack, but also squeezes the yarn with liquid wax attached, squeezing out excess liquid wax from the yarn surface. The squeezed-out liquid wax drips back into the housing 1 and participates in the melting and waxing process again, reducing wax waste. At the same time, it ensures that the wax layer thickness on the yarn surface is uniform, preventing excessive wax coverage from affecting subsequent use. The yarn guide mechanism is located at the top of the mounting plate 2 and is used to guide the movement of the yarn. It includes a top seat 10, a third guide roller 11, a gear 12, a motor 13, and a cover 14.

[0028] The top seat 10 is fixed to the top of the mounting plate 2. Two third guide rollers 11 rotate through the inner walls of both sides of the top seat 10. The two third guide rollers 11 are parallel to each other and have a gap between them for the yarn to pass through. A gear 12 is fixed to the outer wall of each third guide roller 11. The two gears 12 mesh with each other. When one gear 12 rotates, it can drive the other gear 12 to rotate in the opposite direction. A motor 13 and a cover 14 are fixed to one outer wall of the top seat 10. The gear 12 and the motor 13 are both located inside the cover 14. The cover 14 can effectively prevent dust, wax residue and other impurities from adhering to the output shaft of the gear 12 and the motor 13, avoiding impurities from affecting the meshing transmission of the gear 12 and the normal operation of the motor 13, and extending the service life of the components.

[0029] The output shaft of motor 13 is coaxially fixed with one of the third guide rollers 11. After motor 13 is started, the output shaft of motor 13 drives the fixed third guide roller 11 to rotate. When the third guide roller 11 rotates, it drives the other third guide roller 11 to rotate synchronously in the opposite direction through the meshing of gear 12. The two counter-rotating third guide rollers 11 can form a stable traction force, which facilitates the yarn to be pulled through between them. At the same time, during the subsequent waxing process, it can continuously guide the movement of the yarn and ensure that the yarn movement speed is stable. The speed of motor 13 can be adjusted according to the yarn material and waxing requirements to ensure that the yarn has enough time to contact the liquid wax in the housing 1, ensuring that the wax adheres fully, while avoiding uneven wax layer due to excessive movement speed. For example, the top seat 10 is a rectangular frame, and its length is adapted to the width of the mounting plate 2 to ensure a compact and stable structure. The axes of the two third guide rollers 11 inside the top seat 10 are parallel to the transverse direction of the mounting plate 2, and the length direction of the two third guide rollers 11 inside the top seat 10 is consistent with the width direction of the mounting plate 2. The two ends of the two third guide rollers 11 can be rotatably connected to the inner walls on both sides of the top seat 10 through bearings to ensure smooth rotation and no axial movement. The motor 13 is directly connected to the third guide rollers 11 through a coupling, ensuring stable operation. The cover 14 adopts a detachable design, which facilitates regular maintenance and cleaning of internal wax buildup. The motor 13 is a speed-regulating motor, which adjusts the yarn movement speed by controlling the rotation speed of the third guide rollers 11, thereby controlling the yarn tension. The meshing of the gears 12 ensures that the two rollers rotate synchronously, preventing yarn slippage.

[0030] An arc-shaped tube 15 is positioned on one side of the mounting plate 2. The arc shape of the tube 15 conforms to the movement path of the yarn, allowing airflow to more comprehensively cover the yarn surface and ensuring uniform cooling. A clearance opening 21 is provided on the side of the arc-shaped tube 15 closest to the mounting plate 2, and a sealing strip 22 is fixed to one side of the clearance opening 21. The sealing strip 22 reduces airflow leakage from the clearance opening 21, allowing the airflow to act more concentratedly on the yarn and improving the cooling effect. A fan 23 is fixed to the surface of the mounting plate 2. The air outlet of the fan 23 is connected to the arc-shaped tube 15 via a flexible hose. The hose has a certain degree of flexibility, allowing for easy adjustment of its length according to the installation position of the arc-shaped tube 15, ensuring that airflow can be smoothly delivered from the fan 23 into the arc-shaped tube 15. After the fan 23 is started, the airflow generated by the fan 23 will enter the arc-shaped tube 15 through the hose. Under the guidance of the arc-shaped tube 15, the airflow will be blown evenly from the relief port 21 to the yarn passing through the arc-shaped tube 15, quickly taking away the heat of the wax on the surface of the yarn, so that the wax will quickly solidify on the surface of the yarn, forming a stable wax layer, shortening the waxing cycle and improving processing efficiency. For example, in this embodiment, the number of arc-shaped tubes 15 matches the number of lead holes 19.

[0031] This application can be used in the field of yarn processing, or in other fields applicable to this application.

[0032] In another embodiment: a yarn waxing device, which is applied to the field of yarn processing; In another aspect of this embodiment, a positioning mechanism is provided on one side of the mounting plate 2 for positioning the arc-shaped tube 15, and includes a positioning piece 16, a positioning plate 17, and bolts.

[0033] Two positioning pieces 16 are fixedly provided on one side of the arc-shaped tube 15, and the two positioning pieces 16 are located at the upper and lower ends of the arc-shaped tube 15 respectively. The positioning plate 17 is detachably installed on one side of the mounting plate 2. Multiple positioning grooves 18 are opened on one side of the positioning plate 17. The multiple positioning grooves 18 are evenly distributed along the length direction of the positioning plate 17, and the arc-shaped tube 15 can be inserted into one of the positioning grooves 18.

[0034] Two through holes are provided on one side of the positioning plate 17, and bolts are inserted into the through holes. The bolts are threaded to the mounting plate 2.

[0035] When installing the arc-shaped tube 15, first align the relief opening 21 of the arc-shaped tube 15 with the mounting plate 2, allowing the yarn to enter the interior of the arc-shaped tube 15 through the relief opening 21. Then, place the arc-shaped tube 15 against one side of the mounting plate 2 and insert it into the selected positioning groove 18. At this time, the two positioning pieces 16 abut against the upper and lower ends of the positioning plate 17, respectively, restricting the arc-shaped tube 15 from moving in the vertical direction. Pass the bolt through the through hole on the positioning plate 17, align it with the threaded hole on the mounting plate 2, and tighten it to stably fix the positioning plate 17 on the mounting plate 2, thereby positioning the arc-shaped tube 15 and preventing it from shifting during use, ensuring stable cooling effect. Specifically, the positioning piece 16 is integrally formed with the arc-shaped tube 15 and is located on the side opposite to the relief opening 21 and on the vertical part of the arc-shaped tube 15. The shape of the positioning piece 16 is not limited, as long as it can cooperate with the positioning plate 17 to achieve positioning. In this embodiment, it is set to U-shape, and the vertical spacing between the two positioning pieces 16 matches the thickness of the positioning plate 17 to ensure that the upper and lower ends of the positioning plate 17 fit tightly with the positioning piece 16 after the positioning plate 17 is inserted. The positioning plate 17 is a long strip rod with through holes at both ends in the width direction for fixing bolts to pass through and fix the positioning plate 17 to the mounting plate 2. On the side of the positioning plate 17 facing the mounting plate 2, there are multiple positioning grooves 18. The multiple positioning grooves 18 are arranged along the length of the rod and correspond one-to-one with the lead wire holes 19 at the bottom. The size of the positioning grooves 18 is adapted to the cross-sectional shape of the arc tube 15 to ensure that the arc tube 15 is firmly inserted and does not loosen, while facilitating quick disassembly and replacement.

[0036] Workflow: First, push the slide plate 7 to separate the second guide roller 8 from the first guide roller 3. Select the corresponding annular groove according to the yarn thickness, pass one end of the yarn through the gap between them and place it in the annular groove. Release the slide plate 7, and the spring 9 pushes the slide plate 7 back to its original position, causing the first guide roller 3 and the second guide roller 8 to clamp the yarn. Then, pass the free end of the yarn through the lead hole 19 at the bottom of the mounting plate 2, start the motor 13, and use the rotation of the third guide roller 11 to pull the yarn through the two third guide rollers 11. Then, temporarily turn off the motor 13. Next, attach the arc-shaped tube 15 to the mounting plate 2, allowing the yarn to enter the arc-shaped tube 15. Select the appropriate positioning groove 18 and insert it into the arc-shaped tube 15. Fix the positioning plate 17 with bolts to complete the positioning of the arc-shaped tube 15. Then, put the wax block into the housing 1 and start the heating tube 5. The heating tube 5 heats the wax block until it is completely melted into liquid wax. During this period, the temperature sensor monitors the temperature inside the housing 1 in real time to ensure that the temperature is maintained within a suitable range. The motor 13 and fan 23 are restarted. The motor 13 drives the third guide roller 11 to rotate, pulling the yarn to move continuously. The yarn first passes through the liquid wax in the housing 1, so that the wax is evenly adhered. Then, the excess wax is squeezed out by the first guide roller 3 and the second guide roller 8. The excess wax drips back into the collection chamber at the bottom under the action of gravity. Then, it passes through the lead hole 19 and enters the arc tube 15. The airflow generated by the fan 23 quickly cools the wax on the surface of the yarn. The cooled yarn passes out from the arc tube 15, completing the waxing process.

[0037] For example, a temperature sensor is installed on the inner wall of housing 1 near the wax liquid, thereby enabling accurate sensing of the real-time temperature of the wax liquid.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the heating element 5, the motor 13 and the fan 23 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[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.
