Description

Technical Field

[0001] This utility model relates to the field of coating mechanism technology, specifically a spandex core yarn coating mechanism. Background Technology

[0002] In the textile industry, spandex core yarn is widely used due to its high elasticity and other properties. To impart more performance and aesthetic effects to the spandex core yarn, it is usually necessary to coat it with other yarns. However, there are still significant shortcomings in the yarn coating process for spandex core yarn. Currently available coating equipment, whether traditional ring spinning coating machines or more advanced hollow spindle coating machines, as shown in the attached... Figure 1 As shown, most existing methods can only achieve single or double layer coating, with a limited number of coating layers. This makes it difficult to meet diverse production needs, restricts the functionality and versatility of products, and fails to meet market demands for high-quality, multi-functional textile products. Therefore, there is an urgent need for a spandex core yarn coating mechanism capable of multi-layer coating. Utility Model Content

[0003] The present invention mainly provides a spandex core yarn coating mechanism to solve the problem of the limited number of spandex core yarn coating layers in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A spandex core yarn coating mechanism includes a machine base and, from left to right, a feeding roller assembly, a coating assembly, and a guide roller assembly arranged on the machine base. The coating assembly includes a bracket on the machine base, a turntable rotatably connected to the bracket, a power component for rotating the turntable, multiple detachable frames circumferentially distributed on the turntable, and a coating yarn feeder detachably connected to each detachable frame with an adjustable yarn output position. A first yarn through-hole is provided on the turntable. Specifically, the feeding roller assembly and the guide roller assembly can both utilize existing technologies, as long as their technical principles are implemented. The feeding roller assembly mainly assists in feeding the spandex core yarn and limits its movement. The guide roller assembly mainly drives the spandex core yarn to move, thereby assisting in winding. Specifically, the nearest yarn output position is adjusted to the first layer, the next closest to the second layer, and the furthest yarn output position to the outermost coating layer. The number of coating layers and the coating position can be flexibly adjusted according to actual needs. With this structure, the feed roller assembly, together with the guide roller assembly, conveys the spandex core yarn to the turntable. The power unit drives the turntable to rotate, and the disassembly and assembly frame on the turntable rotates accordingly, causing the covering yarn feeder to rotate around the center of the turntable. At the same time, the covering yarn feeder releases the covering yarn to cover the spandex core yarn. The covered yarn continues to be transmitted to the subsequent guide roller assembly through the first yarn through hole, and is moved by the guide roller assembly to facilitate the subsequent winding mechanism to wind up the covered spandex core yarn.

[0006] Furthermore, the coated yarn feeder includes a U-shaped clamping frame, on which a mating frame is provided. A rotatable yarn spool is detachably connected to the mating frame. A discharge limiting guide wheel is rotatably connected to the lower inner end of the U-shaped clamping frame. The outer end of the U-shaped clamping frame is provided with a screw hole and a guide hole. A limiting guide rod is slidably connected in the guide hole. An adjusting screw is threaded into the screw hole. An adjusting plate is rotatably connected to the adjusting screw. The outer end of the limiting guide rod is fixedly connected to the adjusting plate. A winding limiting guide wheel assembly is rotatably connected to the lower outer end of the adjusting plate. Specifically, the yarn spool includes an inner cylinder and an outer cylinder rotatably connected to the outer side of the inner cylinder. A fixing rod is provided on the mating frame. The inner cylinder is sleeved on the fixing rod, and an anti-detachment limiting component is detachably connected to the outer end of the fixing rod. This anti-detachment limiting component can be detachably connected to the fixing rod in any existing method, such as a threaded connection. A yarn threading hole is provided on the mating frame. This structure involves fixing the end of the covering yarn exiting the spool to the spandex core yarn. The covering yarn is then released from the spool by the rotation of the turntable. After initial guidance and limiting by the discharge guide rollers, it is further guided and wound onto the spandex core yarn by the winding guide roller assembly. Rotating the adjusting screw causes the adjusting plate to slide along the limiting guide rod, thus adjusting the position of the winding guide roller assembly and changing the exit position of the covering yarn. The inner cylinder of the spool is fitted onto the fixed rod, and the outer cylinder can rotate relative to the inner cylinder, allowing the covering yarn to be released smoothly. By coordinating the adjusting screw and the limiting guide rod, the exit position of the covering yarn feeder can be flexibly adjusted to accommodate spandex core yarns of different specifications and covering requirements, improving the equipment's versatility. The inner and outer cylinder structure design of the spool ensures smooth release of the covering yarn, and the detachable anti-detachment limiting component facilitates the installation and replacement of the spool, improving work efficiency.

[0007] Furthermore, the U-shaped mounting bracket is provided with a limiting protrusion, and the disassembly / assembly bracket is provided with a limiting groove that mates with the limiting protrusion. With this structure, during installation, the limiting protrusion on the U-shaped mounting bracket is aligned with the limiting groove on the disassembly / assembly bracket and inserted, initially positioning the filament feeder and the disassembly / assembly bracket, facilitating subsequent fixing operations. The cooperation of the limiting protrusion and the limiting groove enables rapid positioning and installation of the filament feeder and the disassembly / assembly bracket, simplifying the installation steps, improving the assembly efficiency of the equipment, and ensuring the accuracy and stability of the installation.

[0008] Furthermore, a baffle is provided at the outer end of the limiting groove, and the baffle is detachably connected to the outer end of the limiting protrusion by bolts. With this structure, after the limiting protrusion is inserted into the limiting groove for initial positioning, the baffle is fixed to the outer end of the limiting protrusion by bolts, preventing the filament feeder from detaching from the assembly / disassembly frame and ensuring its stable operation during turntable rotation. The combination of the baffle and bolts is simple and reliable, effectively preventing the filament feeder from loosening or falling off, ensuring the safety and stability of equipment operation, and facilitating disassembly for maintenance and replacement of the filament feeder.

[0009] Furthermore, the power component includes an electric motor mounted on the machine base, and a power frame mounted on the machine base above the electric motor. A first bevel gear and a second bevel gear meshing with the first bevel gear are rotatably connected within the power frame. The outer end of the second bevel gear is fixedly connected to the transmission end of the turntable. The outer end of the first bevel gear is driven by a belt drive to the output end of the electric motor. A second thread through hole is provided in the middle of the second bevel gear. With this structure, after the motor starts, it drives the first bevel gear to rotate via the belt drive. The first bevel gear meshes with the second bevel gear, transmitting power to the second bevel gear. The second bevel gear drives the turntable fixedly connected to it to rotate, realizing the rotational movement of the coating yarn feeder on the turntable, thereby performing the coating operation on the spandex core yarn. During the coating process, the yarn can continue to be transmitted through the second yarn through hole. The use of a motor, belt drive, and bevel gear transmission method ensures stable and reliable transmission, providing a stable driving force for the turntable. The second yarn through hole on the second bevel gear does not affect the yarn transmission path, allowing the entire coating process to proceed smoothly. At the same time, this power transmission structure has a compact layout, occupies little space, and is conducive to the miniaturization design of the equipment.

[0010] Beneficial effects: 1. By setting multiple circumferentially distributed covering yarn feeders, and with the yarn output position of each feeder adjustable, multi-layer covering of spandex core yarns can be achieved, meeting different production needs and increasing the functionality and diversity of products; 2. The covering yarn feeder and the disassembly frame are detachably connected, allowing workers to quickly replace the pre-replaced yarn spools on the disassembly frame, improving the practicality and flexibility of the equipment; and the detachable design of the yarn spools allows for pre-replacement of the yarn spools and the lead-out of the covering yarn on the matching frame before replacement, saving time on the disassembly frame, facilitating yarn replacement, and further improving production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] As shown in Figures 2 and 3, a spandex core yarn covering mechanism of this embodiment includes a machine base 1, and a feeding roller assembly 2, a covering assembly 3, and a guide roller assembly 4 arranged from left to right on the machine base 1. The covering assembly 3 includes a bracket 301 arranged on the machine base 1, a turntable 302 rotatably connected to the bracket 301, a power component 303 for driving the turntable 302 to rotate, a plurality of disassembly and assembly frames 304 arranged circumferentially on the turntable 302, and a covering yarn feeder 305 detachably connected to each of the disassembly and assembly frames 304 and whose yarn output position is adjustable. A first yarn through hole 306 is provided on the turntable 302. The coated yarn feeder 305 includes a U-shaped clamping frame 3051, on which a mating frame 3052 is provided. The mating frame 3052 has a yarn threading hole. A rotatable yarn spool 3053 is detachably connected to the mating frame 3052. A discharge limiting guide roller 3054 is rotatably connected to the lower inner end of the U-shaped clamping frame 3051. The outer end of the U-shaped clamping frame 3051 is provided with a screw hole and a guide hole. A limiting guide rod is slidably connected in the guide hole. An adjusting screw 3055 is threaded in the screw hole. An adjusting plate 3056 is rotatably connected to the adjusting screw 3055. The outer end of the limiting guide rod is fixedly connected to the adjusting plate 3056. A winding limiting guide roller assembly 3057 is rotatably connected to the lower outer end of the adjusting plate 3056. Specifically, the spool 3053 includes an inner spool and an outer spool rotatably connected to the outside of the inner spool. A fixing rod is provided on the mating frame 3052, and the inner spool is sleeved on the fixing rod. An anti-detachment limiting component is detachably connected to the outer end of the fixing rod. A limiting protrusion 3058 is provided on the U-shaped clamping frame 3051, and a limiting groove that mates with the limiting protrusion 3058 is provided on the disassembly frame 304. A baffle is provided at the outer end of the limiting groove, and the baffle is detachably connected to the outer end of the limiting protrusion 3058 by bolts. The power unit 303 includes an electric motor mounted on the machine base 1, and a power frame mounted on the machine base 1 above the electric motor. A first bevel gear and a second bevel gear meshing with the first bevel gear are rotatably connected within the power frame. The outer end of the second bevel gear is fixedly connected to the transmission end of the turntable 302. The outer end of the first bevel gear is driven by a belt drive to the output end of the electric motor. A second thread through hole is provided in the middle of the second bevel gear.

[0018] During operation, the spandex core yarn is conveyed by the feeding roller assembly 2, passing sequentially through the first yarn through hole 306 on the turntable 302 and the second yarn through hole in the middle of the second bevel gear, reaching the guide roller assembly 4. Simultaneously, the yarn spools 3053 on multiple covering yarn feeders 305 hold the covering yarn. By adjusting the adjusting screw 3055, the adjusting plate 3056 slides along the limiting guide rod, thereby changing the position of the winding limiting guide concave wheel assembly 3057, thus adjusting the yarn output position of the covering yarn feeder 305. The motor starts, driving the first bevel gear to rotate through the belt drive component. The first bevel gear meshes with the second bevel gear, thereby driving the turntable 302 to rotate. The covering yarn feeders 305 on the turntable 302 rotate with the turntable 302, winding the covering yarn onto the spandex core yarn to achieve multi-layer covering. When it is necessary to replace the covered yarn or perform maintenance on the covered yarn feeder 305, the bolts on the baffle can be unscrewed, the U-shaped clamping bracket 3051 can be removed from the disassembly bracket 304, and the yarn spool 3053 can be replaced or other maintenance operations can be performed. Beneficial effects: By setting multiple circumferentially distributed covered yarn feeders 305, and with the yarn output position of each feeder 305 adjustable, multi-layer covering of spandex core yarns can be achieved, meeting different production needs and increasing the functionality and diversity of the product. The covering yarn feeder 305 and the disassembly frame 304 are detachably connected, allowing operators to quickly replace the pre-replaced yarn spool 3053 on the disassembly frame 304, improving the equipment's practicality and flexibility. The detachable design of the yarn spool 3053 allows for pre-replacement of the yarn spool 3053 on the matching frame 3052 and the extraction of the covering yarn before replacement, saving time spent on the disassembly frame 304, facilitating yarn replacement, and further improving production efficiency. The power unit 303 uses an electric motor to drive the turntable 302 via a belt drive and bevel gear transmission. The transmission structure is stable and reliable, ensuring smooth covering process and improving covering quality. The toothed belt of the belt drive is not shown in Figure 2.
