Description

Technical Field

[0001] This utility model specifically relates to a production system for UV-resistant viscose coarse denier flat monofilament, belonging to the field of functional viscose filament production technology. Background Technology

[0002] Coarse denier flat filament viscose is a type of viscose filament, represented by Yafit, also known as Japanese grass or raffia grass, with specifications ranging from 600D to 4000D / 1F. Conventional coarse denier flat filament can meet the requirements for strength, elongation, and dyeing properties. After downstream processing, it can be mainly used to make high-end decorative items, handicrafts, and wall coverings.

[0003] Currently, the equipment used to produce Yafit is usually a modified R535 spinning machine. The main process flow includes: viscose preparation, viscose supply, metering, pre-spinning filtration, spraying, spinning, skeining, washing, drying, and re-skeining / bottle forming, such as CN101135067A, CN102978722A, CN203602777U, CN103614792A, etc.

[0004] However, the production system for UV-resistant adhesive coarse denier flat monofilaments is almost non-existent. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, a production system for UV-resistant viscose coarse denier flat monofilaments is proposed. In this technical solution, temperature sensors, flow meters, injection pumps, and concentration sensors are used to achieve precise and uniform mixing of the viscose solution and UV protectant, creating a blended spinning solution. This solution then undergoes filtration, spinning, and post-treatment processes to form UV-resistant viscose coarse denier flat monofilaments, thus meeting the demand for UV-resistant products.

[0006] To achieve the above technical objectives, the following technical solution is proposed:

[0007] A production system for UV-resistant viscose coarse denier flat monofilament includes a filter device, a buffer tank, a spinning machine, a stranding machine, a washing machine, a dryer, and a coiling machine arranged in sequence. The feed inlet of the filter device is connected to a glue supply pipe.

[0008] The production system also includes a pipeline mixer located in front of the buffer tank station. The inlet of the pipeline mixer is connected to the outlet of the filter device through a viscous liquid pipe. A temperature sensor I is installed on the viscous liquid pipe to detect the temperature of the viscous liquid in real time. The pipeline mixer is located at the rear end, which allows the UV protectant to diffuse rapidly and evenly into the viscous liquid, achieving the purpose of instantaneous mixing of the UV protectant and the viscous liquid, thereby improving the subsequent spinnability.

[0009] The feed inlet of the pipeline mixer is also connected to the ultraviolet protectant storage tank through an ultraviolet protectant pipe. The ultraviolet protectant storage tank is fitted with a temperature regulating jacket, which is connected to a steam pipe and a chilled water pipe. The steam pipe is equipped with a steam regulating valve, and the chilled water pipe is equipped with a chilled water regulating valve. The ultraviolet protectant storage tank is equipped with a temperature sensor II for real-time detection of the temperature of the ultraviolet protectant storage tank.

[0010] Temperature sensor I, temperature sensor II, steam regulating valve, and chilled water regulating valve are all connected to the controller, and a control loop is formed between temperature sensor I, temperature sensor II, the controller, steam regulating valve, and chilled water regulating valve via electrical signals. Ultimately, through blending and spinning, viscose coarse denier flat monofilament with UV protection is obtained, effectively ensuring stable product performance and long-lasting UV protection.

[0011] Preferably, the adhesive liquid tube is equipped with a flow meter.

[0012] Preferably, the UV protectant tube is equipped with an injection pump, which injects the UV protectant precisely into the pipeline mixer at a certain speed and amount.

[0013] Preferably, a concentration sensor, such as ACDR0-70, is installed on the pipeline between the pipe mixer and the buffer tank to detect the concentration of the UV protectant. ACDR0-70 utilizes the principle of refraction, reflecting changes in the concentration of the UV protectant in the adhesive liquid through changes in the angle of light refraction.

[0014] Preferably, the flow meter, syringe pump, and concentration sensor are all connected to the controller, and the concentration sensor, controller, flow meter, and syringe pump form a control loop through electrical signals.

[0015] Preferably, the tube forming machine is equipped with an ultraviolet transmittance detector. This allows for real-time monitoring of the product's UV protection performance, enabling timely adjustments to production parameters and ensuring stable product quality.

[0016] In this technical solution, the filtration device, buffer tank, spinning machine, stranding machine, washing machine, dryer, tube forming machine, viscose liquid pipe and flow meter are used in conjunction with viscose coarse denier flat monofilament and are part of the viscose coarse denier flat monofilament production system.

[0017] The UV protectant storage tank, pipeline mixer, temperature sensor I, UV protectant tube, temperature control jacket, steam pipe, chilled water pipe, steam regulating valve, chilled water regulating valve, temperature sensor II, controller, injection pump, and concentration sensor work together to impart UV protection to viscose coarse denier flat monofilaments.

[0018] In this technical solution, the "sequential arrangement" specifically refers to the arrangement of various equipment components in accordance with the process (i.e. the direction of the filament), showing the positional relationship of each equipment component, and ensuring the smooth progress of the yarn processing technology.

[0019] The positional relationships involved in this technical solution, such as "front side of the workstation," "upper," "outer side," and "between," are defined based on the actual usage conditions and are common terms in this technical field, as well as common terms used by those skilled in the art during actual use.

[0020] The beneficial technical effects of adopting this technical solution are as follows:

[0021] I. This utility model provides a production system for the production process of UV-resistant viscose coarse denier flat monofilament. The system integrates the production equipment for viscose coarse denier flat monofilament with sensors, flow meters, and other components to form a complete production system. This system enables precise temperature control and accurate metering of the UV protectant, allowing for precise and uniform mixing / dispensing of the viscose solution and UV protectant to create a blended spinning solution. Following spinning and post-treatment processes, this results in UV-resistant viscose coarse denier flat monofilament, meeting users' demands for UV-resistant properties in monofilament products.

[0022] II. In this utility model, temperature sensor I, temperature sensor II, controller, steam regulating valve, and chilled water regulating valve form a control loop via electrical signals. Through the specific arrangement of these devices, temperature control is achieved, ensuring that the UV protectant and adhesive solution can mix at a temperature of 18–22°C to form a blended spinning solution. If the temperature of the UV protectant is too high, it will increase the temperature of the adhesive solution, reducing the viscosity and increasing the fluidity of the adhesive. This will lead to poor stability of the adhesive stream during spinning, easily causing problems such as fiber breakage and fuzzing. If the temperature is too low, it will decrease the temperature of the adhesive solution, increasing the viscosity and reducing the fluidity. During spinning, the high-viscosity adhesive will be difficult to extrude from the spinneret, easily causing poor spinning, uneven fiber thickness, and thus affecting product quality and the normal operation of the production process.

[0023] Thirdly, in this invention, a control loop is formed between the concentration sensor, controller, flow meter, and injection pump via electrical signals. The flow meter measures the amount of adhesive liquid, and the injection pump, in conjunction with the concentration sensor, controls the dosage and feed. This precise arrangement of the equipment allows for accurate control of the amount of UV protectant added to the adhesive liquid, ensuring the product's UV protection effect and stability. A low proportion of UV protectant may not achieve the desired UV protection; a high proportion may affect the spinnability of subsequent spinning and waste raw materials; and fluctuating UV protectant proportions result in unstable UV protection, impacting user satisfaction. Therefore, controlling the metering of the UV protectant ensures its proportion in the adhesive liquid remains stable within the required process range, contributing to stable product performance.

[0024] Fourth, the UV-resistant adhesive coarse denier flat monofilament prepared in this utility model can be used in sunshade products, and has good market prospects. Attached Figure Description

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1

[0031] A production system for UV-resistant adhesive coarse denier flat monofilament includes a filter device 1, a buffer tank 2, a spinning machine 3, a stranding machine 4, a washing machine 5, a dryer 6, and a coiling machine 7 arranged in sequence. The feed inlet of the filter device 1 is connected to an adhesive supply pipe.

[0032] The production system also includes a pipeline mixer 9 located in front of the buffer tank 2 station. The inlet of the pipeline mixer 9 is connected to the outlet of the filter device 1 through the adhesive liquid pipe 10. The adhesive liquid pipe 10 is equipped with a temperature sensor I11 for real-time detection of the adhesive liquid temperature. The pipeline mixer 9 at the rear end allows the UV protectant to diffuse rapidly and evenly into the adhesive liquid, achieving instantaneous mixing of the UV protectant and the adhesive liquid, thereby improving the subsequent spinnability.

[0033] The feed inlet of the pipeline mixer 9 is also connected to the ultraviolet protectant storage tank 13 via the ultraviolet protectant pipe 12. The ultraviolet protectant storage tank 13 is fitted with a temperature regulating jacket 14, which is connected to a steam pipe 15 and a chilled water pipe 16. The steam pipe 15 is equipped with a steam regulating valve 17, and the chilled water pipe 16 is equipped with a chilled water regulating valve 18. The ultraviolet protectant storage tank 13 is equipped with a temperature sensor II 19 for real-time detection of the temperature of the ultraviolet protectant storage tank 13.

[0034] Temperature sensor I 11, temperature sensor II 19, steam regulating valve 17, and chilled water regulating valve 18 are all connected to controller 20, and a control loop is formed between them via electrical signals. Ultimately, through blending and spinning, viscose coarse denier flat monofilament with UV protection is obtained, effectively ensuring stable product performance and long-lasting UV protection.

[0035] The UV protectant storage tank 13 is mainly used to store the UV protectant and control its temperature. Subsequently, the UV protectant needs to be mixed with the viscose solution (generally at 18–22°C) to form a blended spinning solution. If the UV protectant temperature is too high, it will raise the temperature of the viscose solution, which is detrimental to the spinnability; if the temperature is too low, it will lower the temperature of the viscose solution, increasing the viscosity and reducing fluidity. During spinning, the high-viscosity viscose will be difficult to extrude from the spinneret, easily causing poor spinning, uneven fiber thickness, and affecting product quality.

[0036] Temperature sensor I11 and temperature sensor II19 are used to detect the temperature of the UV protectant storage tank 13 and the adhesive liquid pipe 10 in real time, respectively. When the temperature of the UV protectant is higher than the temperature of the adhesive liquid, the steam regulating valve 17 is closed and the chilled water regulating valve 18 is opened, which cools down the UV protectant storage tank 13. When the temperature of the UV protectant is lower than the temperature of the adhesive liquid, the steam regulating valve 17 is opened and the chilled water regulating valve 18 is closed, which heats up the UV protectant storage tank 13.

[0037] Ultimately, this allows for effective mixing of the UV protectant and the adhesive solution, ensuring the spinnability of the blended spinning solution.

[0038] Example 2

[0039] Based on Example 1, this example further specifies the ingredients for better formulation:

[0040] A flow meter 21 is installed on the adhesive liquid pipe 10; an injection pump 22 is installed on the ultraviolet protectant pipe 12, which accurately injects the ultraviolet protectant into the pipeline mixer 9 at a certain speed and amount; a concentration sensor 23, such as ACDR0-70, is installed on the pipeline between the pipeline mixer 9 and the buffer tank 2 to detect the concentration of the ultraviolet protectant. The ACDR0-70 uses the principle of refraction to reflect the concentration change of the ultraviolet protectant in the adhesive liquid through the change of the refraction angle of light. The flow meter 21, injection pump 22 and concentration sensor 23 are all connected to the control, and the concentration sensor 23, controller 20, flow meter 21 and injection pump 22 form a control loop through electrical signals.

[0041] The flow meter 21 measures the adhesive in the adhesive tube 10. The UV protectant is precisely injected into the pipe mixer 9 by the injection pump 22 at a predetermined speed and amount. The UV protectant is then rapidly and evenly diffused into the adhesive, achieving instantaneous mixing of the UV protectant and the adhesive (rapid mixing by the mixer makes the mixture more uniform, shortens the subsequent stirring time, saves energy, and improves production efficiency). The concentration sensor 23 is used to detect the concentration of the UV protectant in real time. If the concentration of the UV protectant is lower than the process requirements, the injection frequency of the injection pump 22 is automatically increased. If the detected concentration is too high, the injection frequency of the injection pump 22 is automatically decreased to ensure the accuracy of the UV protectant addition and thus ensure the stability of the monofilament product performance.

[0042] In addition, the forming machine 7 is equipped with a UV transmittance meter. This monitors the UV protection performance of the product in real time, allowing for timely adjustments to production parameters and ensuring stable product quality.
