The humidity sensor selects the HIH series of the American Honeywell company, model HIH-4000-003, to monitor the moisture content of the material, with a range of 0-30% and an accuracy of ±0.2%. When the material temperature exceeds 60℃ or the moisture content exceeds 15%, the system will issue an alarm and adjust the feeding speed or start the cooling and dehumidifying measures.

[0089] The camera 45 selects the acA series industrial camera of the German Basler company, model acA1300-60gm, which is installed at key positions of the feeding system, such as the suction port, the spiral conveyor inlet and the storage tank, to monitor the material flow state in real time. The camera adopts the IE3-020 dustproof design of the German ENGEL company, with a protection level of IP65, which can maintain a good view even in a dusty environment. The camera has a resolution of 1280×720 and a frame rate of 30fps, and is equipped with a HL-2000-FHSA LED fill light of the German Ocean Optics company, which can still provide clear images in a weak light environment.

[0091] Embodiment 6

[0092] As shown in the rough wire stretching device control unit 5, three sets of up-down controllers 51, sensors 52 and cameras 53 are connected with the main controller 11 through special lines. Figure 6

[0093] In one specific embodiment of the present application, the three sets of up-down controllers 51 control the operation of the equipment in the primary stretching zone, the intermediate stretching zone and the fine stretching zone, respectively, and all adopt CX series embedded controllers of Beckhoff Company, model CX5130-0125. Each controller is equipped with an independent motor drive system, which selects Σ-7 series servo motor of YASKAWA Company, model SGM7G-13A7C61, with a motor power of 3kW, adopts servo control technology, and has a rotation speed accuracy of ±0.01rpm and a torque control accuracy of ±0.5%. Preferably, the speed ratio of the three stretching zones is 1:2.5:3.5, which makes the bamboo fiber material gradually oriented during the stretching process, enhances the mechanical strength of the material, and at the same time maintains good degradability.

[0094] The stretching zone heating system adopts XP series heating controller of Herz Company, model XP-1422, and the working temperature of the primary stretching zone is usually controlled at 150-160℃, with a stretching speed of 10-15m / min; the temperature of the intermediate stretching zone is 140-150℃, with a speed of 25-35m / min; and the temperature of the fine stretching zone is 130-140℃, with a speed of 35-50m / min. This temperature gradient design makes the material gradually set during the cooling process, reduces the internal stress, and improves the product size stability.

[0095] ​The sensor 52 includes a tension sensor, a temperature sensor, and a displacement sensor. The tension sensor uses a U2B series force sensor from HBM, Germany, model U2B / 10KN, which monitors the material tension in each stretching zone in real time, with a measurement range of 0-500N and an accuracy of ±0.5N. When an abnormal tension is detected, the system automatically adjusts the relevant parameters, such as motor speed or heating temperature, to restore normal tension. The temperature sensor uses a YTA series temperature transmitter from Yokogawa, Japan, model YTA110-EAA / D1, which monitors the working temperature of each stretching zone, with a measurement range of 0-200℃ and an accuracy of ±0.2℃. The displacement sensor uses an HG-C series laser displacement sensor from Panasonic, Japan, model HG-C1100, which monitors the relative position of the stretching rollers, with a measurement range of 0-100mm and an accuracy of ±0.01mm, ensuring that the stretching rollers maintain the correct relative position and prevent material deviation.

[0096] The camera 53 is an acA series industrial camera from Basler, Germany, model acA2440-75um, installed at key positions of the stretching device to monitor the material stretching state and running trajectory in real time. The camera has a resolution of 1920x1080 and a frame rate of 60fps, equipped with HALCON 20 intelligent image analysis system from MVTec, Germany, which can automatically identify abnormal phenomena such as material rupture, twisting, and thickening. When an abnormality is detected, the system will respond immediately, such as automatically reducing the stretching speed or stopping, etc. In addition, the camera can also measure the material diameter in real time, cooperating with scanCONTROL series laser profilometer from Micro-Epsilon, Germany, model scanCONTROL 2900-50, with a measurement accuracy of ±0.05mm, providing an important basis for quality control.

[0097] In particular, the coarse wire stretching device control unit 5 is also equipped with AS series automatic material receiving system from Savoldi, Switzerland, model AS-2500. When the material is about to run out, the system will automatically slow down and prepare for material receiving. During the material receiving process, the new and old materials are connected through a hot melt joint, with a joint strength of more than 85% of the normal material, and a material receiving success rate of more than 99%, greatly reducing the downtime and material waste caused by material replacement.

[0098] In addition, the stretching device is also equipped with EcoCClear series automatic cleaning device from Dürr, Germany, model EcoCClear-2000, which periodically cleans the impurities and deposits on the surface of the stretching rollers, ensuring the smoothness of the stretching roller surface and preventing the scratching of the material surface. The cleaning cycle is usually set to 8-12 hours, with a cleaning time of about 2-3 minutes, which has little effect on production efficiency.

The shear speed can be adjusted within the range of 0-200 rpm to adapt to different material and different specification cutting requirements. Preferably, the shear knife has the SpeedLine SL1 automatic knife grinding function of Hoffmann Company in Germany, model SL1-100, which automatically performs cutter dressing every 8 hours of operation, with a dressing time of about 3 minutes, greatly extending the service life of the cutter while maintaining the cutting quality.

[0102] The roller propulsion controller 62 adopts the SINAMICS G120 series frequency converter of Siemens Company in Germany, model 6SL3224-0BE24-0AA0, to control the material conveying speed and pressure. The roller adopts the RM series pattern design roller of Kärcher Company in Germany, model RM 1400, to increase the contact area and friction force with the material, and the propulsion is more stable. The roller surface adopts the ContiTech hard rubber material of Continental Company in Germany, model ContiTech CR-80, with hardness Shore A 80-85, which can provide sufficient grip without damaging the material. The propulsion speed can be steplessly adjusted within the range of 0-50 m / min, with a speed control accuracy of ±0.1 m / min. In particular, the roller pressure can be adjusted by the ITV series pneumatic system of SMC Company in Japan, model ITV3050-312L, with a pressure range of 0-0.8 MPa, so that the system can adapt to materials of different hardness and diameter.

[0103] The camera 63 is an acA series industrial camera from Basler, Germany, model acA1920-155um, installed in the shearing area to monitor the shearing process and particle quality in real time. The camera has a resolution of 1920x1080 and a frame rate of 120fps, capable of clearly capturing the high-speed shearing process. The system is equipped with HALCON 20 intelligent image analysis software from MVTec, Germany, which can automatically measure particle size and detect abnormal particles such as oversized and irregularly shaped particles. When detecting 5 consecutive particles with sizes outside the set range (usually ±10%), the system will automatically adjust the shearing parameters or issue an alarm.

[0104] In addition, the particle shearing device control unit 6 is also equipped with an NT series automatic chip removal system from Kärcher, Germany, model NT 75 / 2 Tact Me Tc, and an MD500 counting system from Bosch, Germany, model MD500-X40. The chip removal system uses pneumatic blowing combined with negative pressure adsorption to clean the shearing area debris in time, preventing accumulation from affecting shearing quality and equipment operation. The counting system can count the number of sheared particles in real time, with an accuracy of ±0.5%, providing data support for production management and quality control.

[0105] In particular, the shearing device is designed with a C4000 series safety protection mechanism from SICK, Germany, model C4000 Advanced 1200, with photoelectric protection devices in the operating area. When detecting personnel entering the danger zone, the system will immediately stop running. In addition, the control system is equipped with PNOZmulti series overload protection function from Pilz, Germany, model PNOZ m B0, which will automatically shut down when detecting that the shearing force exceeds the set value (usually 120% of the motor rated torque), avoiding equipment damage and safety accidents.

[0106] It is worth mentioning that the intelligent adjustment function of the particle shearing device control unit 6 is a major feature of the present application. The system uses SIMATIC ET 200SP series control module from Siemens, model 6ES7155-6AU00-0BN0, which can automatically adjust shearing parameters such as shearing speed, pushing speed and shearing force according to the characteristics of the upstream material (such as diameter, hardness, etc.) and the needs of the downstream process, achieving the best shearing effect. For example, when detecting a 5% increase in material diameter, the system will automatically reduce the pushing speed by about 8% and increase the shearing force by about 10%, ensuring that the particle size remains within the ideal range.

[0109] In an embodiment of the present application, the cooling tower controller 71 is a Metasys series controller from Johnson Controls, model MS-FEC2611-0, responsible for controlling the fan speed, water spray amount, and operating state of the cooling tower. The cooling tower is an NC series counterflow cooling tower from Marley, model NC8414, with a cooling efficiency about 15% higher than that of a crossflow cooling tower. The fan is a SIMOTICS series variable frequency speed regulation technology from Siemens, model 1LE1501-2AB53-4AB0, with a power of 7.5kW, a speed range of 0-1200rpm, and an air volume adjustable in the range of 0-30000m³ / h. Preferably, the fan blades are made of Ultramid composite material from BASF, model Ultramid A3WG10 BK00564, with lightweight design reducing energy consumption and good corrosion resistance. The outlet water temperature of the cooling tower is usually controlled at 25-30℃, which is 3-5℃ higher than the ambient temperature, achieving good energy utilization efficiency.

In addition, the water quality control system regularly monitors water quality parameters, using an IQ Sensor Net series water quality monitoring system from WTW, model DIQ / S 282, such as pH value, turbidity, and conductivity, which automatically starts the water treatment program or sends an alarm when the parameters are outside the normal range.

[0111] The down-pressing guide roller controller 73 adopts a CX series controller of Beckhoff Company in Germany, model CX5120-0125, to control the speed, pressure and position of the guide roller.

The roller surface adopts a ContiTech WR-70 of Continental Company in Germany, with a Shore A hardness of 70-75, which has good wear resistance and adhesion. The roller pressure is controlled by a VIPA series pneumatic system of Festo Company in Germany, model VIPA 321-1BH00, with a pressure range of 0-0.6 MPa, which can be automatically adjusted according to the material properties. Preferably, the guide roller is provided with an automatic alignment function of MSK series of Bosch Rexroth Company in Germany, model MSK060C-0300, which can automatically adjust the roller position when the material deviation is detected to be more than ±2 mm, so as to make the material return to the center position.

The intelligent energy-saving system can automatically adjust the cooling tower fan speed and water pump flow according to the environmental temperature, material temperature and cooling demand, so as to save energy as much as possible while meeting the cooling demand. For example, in the case of low environmental temperature (such as below 20℃), the system can reduce the fan speed by about 30%, which not only meets the cooling demand, but also saves energy. The emergency cooling system can start the standby cooling unit when detecting abnormal cooling (such as the cooling water temperature exceeding 40℃), so as to ensure the production continuity and product quality.

[0113] In addition, the intelligent adjustment function of the water circulation cooling device control unit 7 is another feature of the utility model. The system adopts a SIMATIC S7-1200 series controller of Siemens Company in Germany, model 6ES7212-1BE40-0XB0, which can automatically adjust the cooling parameters such as water temperature, water flow and contact time according to the material temperature of the upstream process and the temperature demand of the downstream process, so as to realize accurate cooling control.

The intelligent temperature control system automatically adjusts the cooling parameters such as air volume, air pressure and cooling time according to the material characteristics, environmental temperature and downstream process requirements, to achieve precise temperature control. For example, in a high temperature environment in summer (such as an environmental temperature exceeding 30℃), the system will automatically increase the air volume by about 20% and reduce the chain speed by about 15%, to ensure that the material achieves the desired cooling effect. The automatic cleaning system regularly cleans the impurities on the surface of the chain and in the air duct to prevent blockage and affect the cooling effect. The cleaning cycle is usually set to 24 hours, and the cleaning time is about 5 minutes, which has little effect on production efficiency.

[0120] In addition, the energy recovery function of the air cooling device control unit 8 is a highlight of the present application. The system uses a 64 series heat energy recovery device of Baelz Company, Germany, model Baelz 64-ML, to guide the exhaust warm air to the area that needs to be heated (such as the drying area or the preheating area), to realize the secondary utilization of energy and save about 20% of energy.
