Description

Technical Field

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

[0002] Spandex yarn is a type of yarn with spandex as its main component. Spandex yarn has excellent elasticity and resilience, providing good stretchability for clothing, and is therefore widely used in the textile industry. During the production process, spandex yarn needs to be coated with adhesive to improve its abrasion resistance, enhance elasticity, improve hand feel, and add specific functions. However, the current coating method generally involves spraying adhesive onto the surface of the spandex yarn. This method results in only a portion of the adhesive being applied to the yarn, leading to adhesive waste and potentially uneven application. Furthermore, after coating, the spandex yarn undergoes a period of conveying before entering the curing chamber. During this process, adhesive may drip from the spandex yarn, not only soiling the equipment but also affecting the production quality of the spandex yarn.

[0003] To address the aforementioned issues, CN221360753U discloses a "coating and curing device for spandex yarn." This device uses a coating tube tightly attached to the spandex yarn, allowing adhesive from the coating tank to be applied evenly through holes in the coating tube. The coated spandex yarn then enters a curing chamber equipped with a heat source to cure the adhesive on the spandex yarn, preventing adhesive drips from the yarn from soiling the equipment. However, this device still has certain drawbacks in practical use. For example, the adhesive needs to pass through the holes in the coating tube to be applied to the spandex yarn, but some adhesive may remain inside the internal gear ring, making it difficult to clean. Natural curing of the adhesive can affect the rotation between the gear and the internal gear ring, thus affecting the coating of the spandex yarn. Furthermore, although the device has a heat source to immediately cure the coated spandex yarn, different adhesives have different curing methods; for example, some adhesives require natural drying at room temperature, and this device cannot accelerate the curing process using a heat source. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a coating and curing mechanism for spandex yarn. The coating component can be used to coat spandex yarn, and the coating component is easy to disassemble and clean.

Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-6 As shown, a gluing and curing mechanism for spandex yarn includes: a gluing frame 1, a drying frame 101 on one side of the outer end of the gluing frame 1, and a gluing assembly inside the gluing frame 1 for applying glue to the spandex yarn. The gluing assembly includes: a frame 2, a sponge block 201, a glue outlet 202, and a movable plate 203. A drying assembly inside the drying frame 101 is used to dry the glue on the spandex yarn. The drying assembly includes: a support plate 5, a fan 501, and a heating wire 502.

[0023] The coating frame 1 has a surrounding frame 2 inside, and two sponge blocks 201 inside the surrounding frame 2. Each sponge block 201 has a glue outlet 202 on its top. Each of the two sponge blocks 201 has a movable plate 203 on one side of its outer end. When applying glue to the spandex yarn, one end of the spandex yarn is passed between the two sponge blocks 201. The two movable plates 203 are moved toward the sponge blocks 201 respectively, so that the two sponge blocks 201 are pressed together and the outer side of the spandex yarn is tightly pressed against the two sponge blocks 201. At this time, water is injected into the sponge blocks 201 through the glue outlet 202. The glue flows through the fine holes in the sponge blocks 201 to the spandex yarn and adheres to the outer side of the spandex yarn.

[0024] The adhesive application frame 1 has an adhesive storage tank 3 installed at its bottom and a pump 301 installed at its top. One side of the pump 301 has a suction pipe 304, and the other side is connected to a diversion pipe 302. The tops of both adhesive outlets 202 are connected to the diversion pipe 302. Electric telescopic rods 303 are installed on both sides of the outer end of the frame 2. One end of each electric telescopic rod 303 is connected to a movable plate 203. When the adhesive outlets 202 are used, the pump 301... The glue inside the glue storage tank 3 is pumped into the diversion pipe 302 using the suction pipe 304, and then transported to the glue outlet 202 through the diversion pipe 302. The electric telescopic rod 303 is used to adjust the position of the movable plate 203. A feeding pipe and a discharge pipe are connected to one side of the outer end of the glue storage tank 3, and a control valve is installed on the outside of the discharge pipe. The feeding pipe is used to inject glue or water into the glue storage tank 3, and the discharge pipe can discharge the wastewater when cleaning the inside of the glue storage tank 3.

[0025] The sponge block 201 has a mounting block 4 at its bottom. Two vertical plates 401 are fixedly connected to one side of the inner wall of the glue application frame 1. The two vertical plates 401 are located on both sides of the outer end of the mounting block 4. Two baffles 402 are set inside the glue application frame 1. Insert blocks 403 are connected to both sides of the bottom of the two baffles 402. Four slots 404 are opened on one side of the inner wall of the glue application frame 1. Side plates 405 are connected to the outer end of the two baffles 402. When it is necessary to clean and replace the sponge block 201, The baffle 402 is lifted upwards by the side plate 405 until the insert 403 slides completely out of the slot 404. Then the baffle 402 is removed from the glue application frame 1. Next, the mounting block 4 is slid out between the two vertical plates 401 until the mounting block 4 is removed from the glue application frame 1. At this time, it is convenient to clean and replace the sponge block 201 inside the frame 2. When the mounting block 4 is placed inside the glue application frame 1, the vertical plates 401 and the baffle 402 limit the mounting block 4.

[0026] The drying frame 101 has support plates 5 installed on both sides of its inner wall. Fans 501 are installed on the top of the two support plates 5. Heating wires 502 are installed on the back of the two fans 501. When the spandex yarn passes through the drying frame 101, the fans 501 can blow air onto the outside of the spandex yarn to quickly dry the glue on the outside of the spandex yarn. The heating wires 502 can heat the air passing through the fans 501, so that the fans 501 can blow air onto the spandex yarn. A control panel is installed on one side of the outer end of the drying frame 101 to control the start and stop of the heating wires 502, fans 501, electric telescopic rods 303, pumps 301 and electric push rods 703. Therefore, the heating wires 502 can be activated or deactivated depending on the type of glue, and the winding speed of the winding mechanism 701 can be changed to ensure that the glue on the spandex yarn dries.

[0027] The air drying frame 101 has air inlets 6 on both sides of its outer end, and a receiving frame 601 is connected to one side of the outer end of the mounting block 4. The air inlets 6 are used to ensure the air intake of the fan 501, while the receiving frame 601 can collect the glue dripping from the spandex yarn, thereby preventing the glue from dripping onto the top of the base 7 and making it difficult to clean.

[0028] The glue storage box 3 has a base 7 connected to its bottom. A winding mechanism 701 is installed on one side of the top of the base 7, and an unwinding mechanism 702 is installed on the other side of the top of the base 7. An electric push rod 703 is installed on one side of the outer end of the glue storage box 3. One end of the electric push rod 703 is connected to the unwinding mechanism 702. When using this device, the spandex yarn to be coated is wound around the unwinding mechanism 702. Then, one end of the spandex yarn on the unwinding mechanism 702 is passed between the two sponge blocks 201, then through the drying frame 101 and the surrounding frame 2, and wound around the winding mechanism 702. On mechanism 701, the position of unwinding mechanism 702 is adjusted by electric push rod 703 so that the spandex yarn is always in a straight state. Then, while unwinding mechanism 702 unwinds, winding mechanism 701 winds up, thereby continuously applying glue and air drying to the wound spandex yarn. The winding mechanism 701 and unwinding mechanism 702 are existing structures in the field of winding and unwinding technology, and this application has not improved them. Therefore, this application does not describe in detail the winding and unwinding process of winding mechanism 701 and unwinding mechanism 702.

[0029] Working principle:

[0030] When using this device, the spandex yarn to be coated with adhesive is wound onto the unwinding mechanism 702. One end of the spandex yarn on the unwinding mechanism 702 is then passed between two sponge blocks 201, through the drying frame 101 and the surrounding frame 2, and wound onto the winding mechanism 701. The position of the unwinding mechanism 702 is then adjusted using the electric push rod 703 to keep the spandex yarn taut. The unwinding mechanism 702 unwinds while the winding mechanism 701 winds up, continuously coating and drying the wound spandex yarn. When coating the spandex yarn, the two movable plates 203 are moved towards the sponge blocks 201, causing the two sponge blocks 201 to adhere to each other, thus tightly binding the outer side of the spandex yarn to the two sponge blocks 201. When the adhesive is tightly bonded, the pump 301 uses the suction pipe 304 to pump the adhesive from the storage tank 3 into the distribution pipe 302, and then the adhesive is delivered to the dispensing head 202 through the distribution pipe 302. The adhesive is then injected into the sponge block 201 through the dispensing head 202. The adhesive flows through the fine pores in the sponge block 201 to the spandex yarn and adheres to the outside of the spandex yarn. Due to the continuous winding of the winding mechanism 701, the coated spandex yarn passes through the drying frame 101. The fan 501 blows air onto the outside of the spandex yarn, thereby quickly drying the adhesive on the outside of the spandex yarn. The heating wire 502 is provided to heat the air passing through the fan 501, so that the fan 501 can blow air onto the spandex yarn.
