Composite layer structure of antistatic aramid yarn winding contact roller

Abstract

This application discloses a composite layer structure for an antistatic aramid yarn winding contact roller, belonging to the field of warping machine technology. It includes a base plate with a support structure at its bottom and a guide structure at its top. The design is novel and the device ingenious. By incorporating an antistatic mechanism, a water tank, a water pump, a water supply pipe, a vertical plate, a horizontal pipe, and spray nozzles, static electricity generated between the yarn and the take-up roller during winding is avoided. During winding, the water pump is activated to extract water from the tank and transport it through the water supply pipe to the horizontal pipe. Finally, the water is atomized into fine mist by multiple spray nozzles and sprayed out to wet the yarn being wound and lower the ambient temperature. This mechanism, by using water mist sprayed from the spray nozzles to wet the yarn being wound, avoids frictional static electricity caused by dry air and excessively high temperatures, greatly improving the practicality of the device.

Description

Technical Field

[0001] This application relates to the field of warping machine technology, and in particular to the composite layer structure of antistatic aramid yarn winding contact rollers. Background Technology

[0002] Winding is the process in textile production of winding semi-finished or finished products into rolls using specific techniques. Its core function is to realize the storage, transportation and inter-process transfer of products. Common roll forms include cylindrical and conical shapes, which require a combination of rotation and reciprocating motion to complete the spiral yarn arrangement.

[0003] As a high-performance fiber material, aramid yarn is prone to static electricity during the winding process due to friction and separation between the yarn and the contact roller. The presence of static electricity causes the aramid yarn to attract and entangle with each other, affecting the normal winding of the yarn, resulting in frequent yarn breakage and reduced production efficiency. At the same time, static electricity also attracts dust and impurities from the air, increasing the fuzz on the yarn surface, which seriously affects the quality of the aramid yarn and its subsequent processing performance.

[0004] Therefore, this application proposes a composite layer structure for an antistatic aramid yarn winding contact roller. Utility Model Content

[0005] The composite layer structure of the antistatic aramid yarn winding contact roller proposed in this application solves the problems mentioned in the background art. The composite layer structure of the antistatic aramid yarn winding contact roller, by setting an antistatic mechanism, a water tank, a water pump, a water supply pipe, a vertical plate, a horizontal pipe and a spray head, can avoid static electricity generated between the yarn and the take-up roller during yarn winding. The mechanism wets the yarn being wound by spraying water mist from the spray head, which can avoid frictional charging caused by dry air and excessive temperature, and greatly improves the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A composite layer structure for an antistatic aramid yarn winding contact roller includes a base plate, a support structure at the bottom of the base plate, a guide structure at the top of the base plate, a tensioning mechanism at the top of the base plate located on one side of the guide structure, a winding structure at the top of the base plate located on one side of the tensioning mechanism, and an antistatic mechanism at the top of the base plate located on one side of the winding structure. The antistatic mechanism includes a water tank fixedly connected to the top of the base plate, a water pump installed inside the water tank, and a water supply pipe fixedly connected to the outlet of the water pump. A vertical plate is fixedly connected to the top of the base plate, a horizontal pipe is fixedly connected to the inner side of the vertical plate and is fixedly connected to the water supply pipe, and the horizontal pipe communicates with the water supply pipe. Multiple spray nozzles are fixedly connected to the bottom of the horizontal pipe, and the spray nozzles face the winding structure. A threading structure is provided at the top of the base plate, located on the other side of the guide structure, and a yarn leveling mechanism is provided outside the threading structure.

[0008] In a preferred embodiment, the support structure includes a support leg, which is fixedly connected to the bottom of the base plate, and a friction pad is installed on the bottom of the support leg.

[0009] The device can be supported by support legs, and friction pads are used to increase the friction between the support legs and the ground, thereby improving the stability of the device and enhancing its practicality.

[0010] In a preferred embodiment, the guide structure includes a fixed rod, which is fixedly connected to the top of the base plate. A connecting rod is rotatably connected to the inner side of the fixed rod, and a guide roller is fixedly connected to the outer side of the connecting rod.

[0011] When the yarn passes through the guide roller, the yarn drives the guide roller to rotate, which plays a guiding role and thus improves the practicality of the device.

[0012] In a preferred embodiment, the tensioning mechanism includes a U-shaped rod, which is fixedly connected to the top of the base plate. A tensioning motor is fixedly connected to the top of the base plate. A threaded rod is fixedly connected to the output end of the tensioning motor, and the top end of the threaded rod is rotatably connected to the U-shaped rod. A lifting rod is threadedly connected to the outside of the threaded rod. A limit rod is fixedly connected to the top of the base plate, and the limit rod is fixedly connected to the U-shaped rod on the other side. The lifting rod is slidably connected to the limit rod, and a tensioning roller is rotatably connected to the outside of the lifting rod.

[0013] The tensioning motor drives the threaded rod to rotate, and under the limit of the limit rod, the threaded rod drives the lifting rod to rise and fall. When the yarn passes through the bottom of the tensioning roller, the guide roller cooperates with the tensioning roller to adjust the tension of the yarn, which facilitates the winding of the yarn and improves the practicality of the device.

[0014] In a preferred embodiment, the winding structure includes a side plate, which is fixedly connected to the top of the bottom plate. The top of the side plate has an installation groove. A T-shaped plate is fixedly connected to the outer surface of one side plate. A winding motor is fixedly connected to one side of the T-shaped plate, and the output end of the winding motor passes through the T-shaped plate. A detachable rod is fixedly connected to the output end of the winding motor, and the detachable rod is rotatably connected to the installation groove. A winding roller is fixedly connected to the outside of the detachable rod.

[0015] The device uses a winding motor to drive a detachable rod to rotate, which in turn drives the winding roller to rotate, thus achieving the purpose of winding the yarn and improving the practicality of the device.

[0016] In a preferred embodiment, the detachable rod includes a threaded ring, which is formed on the surface of the detachable rod. A plug is fixedly connected to the end face of one section of the detachable rod, and a slot is formed on the end face of the other section of the detachable rod, with the slot slidably connected to the plug. A fixing ring is threadedly connected to the outside of the detachable rod through the threaded ring.

[0017] By twisting the retaining rings on both sides of the detachable rod to expose the insert and slot, and then pulling the detachable rod upward, the take-up roller can be pulled out, which makes it easier to take out the wound yarn, thereby improving the practicality of the device.

[0018] In a preferred embodiment, the threading structure includes an auxiliary plate, which is fixedly connected to the top of the base plate. A crossbar is fixedly connected to the inner side of the auxiliary plate, and a slider is slidably connected to the outer side of the crossbar. A threading ring is fixedly connected to the top of the slider, and a threading hole is provided on the surface of the threading ring.

[0019] The yarn passes through the threading hole, allowing for orderly winding and preventing it from becoming too messy or even knotted, thus improving the practicality of the device.

[0020] In a preferred embodiment, the line-leveling mechanism includes a first plate, which is fixedly connected to the outside of an auxiliary plate on one side. A line-leveling motor is fixedly connected to the top of the first plate and passes through the first plate at the top. An active rod is fixedly connected to the output end of the line-leveling motor. An active disc is fixedly connected to the outside of the active rod. A transmission steel plate is driven to the outside of the active disc and passes through the auxiliary plate. A clamping block is fixedly connected to one side of the slider and is fixedly connected to the transmission steel plate. A second plate is fixedly connected to the outside of the other auxiliary plate. A driven rod is fixedly connected to the bottom of the top second plate and is fixedly connected to the second plate at the bottom. A driven disc is rotatably connected to the outside of the driven rod and is driven by the transmission steel plate.

[0021] The yarn leveling motor drives the drive rod to rotate, which in turn drives the drive disc to rotate. The rotation of the drive disc drives the transmission steel plate, forming a closed transmission loop with the help of the driven disc. Since the transmission steel plate is fixedly connected to the clamping block, and the clamping block is fixedly connected to the slider, the reciprocating rotation of the output end of the yarn leveling motor can drive the slider to slide back and forth outside the crossbar, so that the yarn can be evenly wound around the outside of the take-up roller during the winding process, thereby improving the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] The composite layer structure of this antistatic aramid yarn winding contact roller, through the inclusion of an antistatic mechanism, water tank, water pump, water supply pipe, vertical plate, horizontal pipe, and spray nozzles, can prevent static electricity generated between the yarn and the winding roller during winding. During winding, the water pump is activated to extract water from the water tank and transport it through the water supply pipe to the horizontal pipe. Finally, the water is sprayed out as a fine mist through multiple spray nozzles to wet the yarn being wound and reduce the ambient temperature. This mechanism wets the yarn being wound by spraying water mist from the spray nozzles, which can prevent frictional static electricity caused by dry air and excessive temperature, greatly improving the practicality of the device.

[0024] The composite layer structure of this antistatic aramid yarn winding contact roller, through the setting of a yarn leveling mechanism, a first plate, a yarn leveling motor, a drive rod, a drive disc, a transmission steel plate, a clamping block, a second plate, a driven rod, and a driven disc, enables the yarn to wind evenly. The yarn leveling motor drives the drive rod to rotate, which in turn drives the drive disc to rotate. The rotation of the drive disc drives the transmission steel plate, forming a closed transmission loop with the help of the driven disc. Since the transmission steel plate is fixedly connected to the clamping block, and the clamping block is fixedly connected to the slider, the reciprocating rotation of the output end of the yarn leveling motor can drive the slider to slide back and forth outside the crossbar, so that the yarn can be evenly wound on the outside of the take-up roller during the winding process, greatly improving the practicality of the device.

[0038] Reference Figure 1-4 The top of the base plate 1 is provided with a threading structure 7, which is located on the other side of the guide structure 3. The threading structure 7 includes an auxiliary plate 71, which is fixedly connected to the top of the base plate 1.

A threading ring 74 is fixedly connected to the top of the slider 73, and a threading hole 75 is opened on the surface of the threading ring 74. The yarn passes through the threading hole 75, which can orderly wind up the yarn and prevent it from being too messy or even knotted during winding, thereby improving the practicality of the device.

[0039] Reference Figure 1-4 The threading structure 7 is externally equipped with a thread-leveling mechanism 8. The thread-leveling mechanism 8 includes a first plate 81, which is fixedly connected to the outside of an auxiliary plate 71 on one side. A thread-leveling motor 82 is fixedly connected to the top of the first plate 81, and the thread-leveling motor 82 passes through the first plate 81 located at the top. An active rod 83 is fixedly connected to the output end of the thread-leveling motor 82. An active disc 84 is fixedly connected to the outside of the active rod 83.

The rotation of the driving disk 84 will drive the transmission steel plate 85 to rotate. A closed transmission loop is formed with the help of the driven disk 89. Since the transmission steel plate 85 is fixedly connected to the clamping block 86, and the clamping block 86 is fixedly connected to the slider 73, the reciprocating rotation of the output end of the yarn leveling motor 82 can drive the slider 73 to slide back and forth outside the crossbar 72, so that the yarn can be evenly wound on the outside of the take-up roller 56 during the winding process, thereby improving the practicality of the device.

[0040] Working principle: When the device is working, as the yarn passes through the guide roller 33, the yarn drives the guide roller 33 to rotate, which plays a guiding role. The tension motor 42 drives the threaded rod 43 to rotate. Under the limit of the limit rod 45, the threaded rod 43 drives the lifting rod 44 to rise and fall. When the yarn passes through the bottom of the tension roller 46, the guide roller 33 and the tension roller 46 cooperate to adjust the yarn tension, which facilitates the winding of the yarn. The winding motor 54 drives the detachable rod 55 to rotate, and the detachable rod 55 drives the winding roller 56 to rotate, so as to achieve the purpose of winding the yarn. During winding, the water pump 62 is started to draw water from the water tank 61 and transport it through the water pipe 63 to the horizontal pipe 65. Finally, the water is sprayed out as a fine mist through multiple spray nozzles 66 to wet the yarn being wound and reduce the ambient temperature. Twisting the retaining ring 554 on both sides of the detachable rod 55 exposes the insert block 552 and slot 553. Pulling the detachable rod 55 upwards pulls out the take-up roller 56, making it easier to remove the wound yarn. The yarn passes through the threading hole 75, allowing for orderly winding and preventing it from becoming too messy or even knotted. The evenly winding motor 82 drives the drive rod 83 to rotate, which in turn drives the drive disc 84 to rotate. The rotation of the drive disc 84 drives the transmission steel plate 85, forming a closed transmission loop with the help of the driven disc 89. Since the transmission steel plate 85 is fixedly connected to the clamping block 86, and the clamping block 86 is fixedly connected to the slider 73, the reciprocating rotation of the output end of the evenly winding motor 82 can drive the slider 73 to slide back and forth outside the crossbar 72, allowing the yarn to be evenly wound around the outside of the take-up roller 56 during the winding process.
