Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glue dispensing equipment, and particularly relates to a splicing glue dispensing machine and method for prefabricated components. BACKGROUND

[0002] The splicing glue of prefabricated components is usually an epoxy resin-based material; the epoxy resin material has high modulus, high strength, high adhesion, fatigue resistance and creep resistance, etc., but also has some deficiencies, mainly manifested as: high viscosity, low mixing efficiency, uneven mixing, too high viscosity in winter, and the like, which cannot be constructed; these deficiencies directly restrict the construction progress of many prefabricated component splicing projects, such as wind power tower splicing, bridge prefabricated component splicing, subway pipe gallery splicing, and the like.

[0003] Among them, the wind power tower is a key support structure of a wind power generation device, and the use of epoxy splicing glue is crucial in the manufacturing process; however, in the field construction, the epoxy splicing glue is usually directly poured into the B component into the A component barrel, the A and B components are mixed by using a handheld mixer, the glue is taken out by using a glue spatula after being mixed uniformly, and the glue is manually scraped and coated on the pipe piece of the wind power tower.

[0004] However, this construction method has many problems: 1, when the A component is manually mixed, the A component is easily adhered to the bottom or wall of the barrel, so that the A component cannot be fully mixed with the B component, the A / B component which is not fully mixed is coated on the pipe piece of the wind power tower, and the problem of long-term non-curing is easily caused, and the bonding strength of the glue material which is not fully mixed does not meet the standard, which directly affects the safety of the wind power tower; 2, the mixing time of manual mixing is difficult to strictly control, and the reaction progress of the glue material is not consistent on the same pipe piece, which affects the overall curing speed of the glue material; 3, the glue material is easily uneven in thickness, and the problems of missing coating or overcoating are easily caused when the glue material is manually scraped and coated; 4, the construction efficiency of manual mixing and scraping is low, and the problem of inconsistent construction effect of the glue material is easily caused.

[0005] In addition, in the wind power tower splicing installation, the volume of the wind power tower is huge, the demand for the amount of epoxy splicing glue is large, and the sealing and bonding quality of the splicing part is directly related to the stability and safety of the tower. Therefore, the accuracy of the ratio of the two glues is extremely high. The existing construction method cannot realize the accurate ratio of the two glues, which easily leads to unstable performance of the splicing part, directly affecting the quality of the wind power tower. At the same time, the epoxy splicing glue for the wind power tower usually has high viscosity. In the glue conveying process of the general glue machine, the flow rate is not uniform and even blocked, which seriously affects the continuity and working efficiency of the glue. In addition, due to the special production environment and process requirements of the wind power tower, the adaptability of the ordinary glue machine to different working conditions is poor, and it cannot meet the diversified construction demand. Furthermore, the general glue machine cannot realize the self-cleaning function, and the mixed glue easily solidifies in the equipment, causing the equipment to stop running. SUMMARY

[0026] 6. The mixing mechanism of this invention employs a uniquely designed combination of a static mixer and a dynamic mixer. Inside the mixing system, a high-speed rotating spiral mixer in the dynamic mixer initially disrupts the flow pattern of the rubber compound, achieving preliminary mixing of rubber compounds A and B. The spiral mixer dynamically mixes and directionally conveys the rubber compound through a spiral mixing plate, enabling preliminary uniform mixing of rubber compounds A and B. The spiral mixing plate is made of a special wear-resistant material, maintaining good performance during the mixing of high-viscosity rubber compounds. Under the action of the high-speed rotating spiral mixing plate, components A and B... The component rubber compounds can be fully and uniformly mixed to ensure the stability of the mixed rubber compound's properties. Subsequently, the rubber compound enters the static mixer, where static mixing baffles distributed in a corrugated mixing tube statically mix the initially mixed rubber compound. This not only prevents the initially mixed rubber compound from solidifying but also remixes it, improving the mixing degree and uniformity of the initially mixed rubber compound. In addition, the squeezing action of the static mixer can also expel air from the mixed rubber compound, increasing the density of the mixed rubber compound and thus improving the mechanical strength of the cured rubber compound.

[0027] 7. This invention uses a high-performance servo motor as the driving component for the volumetric metering pumps on conveying pipes A and B. Through a high-precision encoder and motor driver, the motor speed is precisely controlled. The motor driver receives speed commands from the automatic control system, enabling high-precision control of the motor speed, thereby accurately adjusting the flow rate of the rubber compound. This drive device has a three-loop control system consisting of a speed loop, a current loop, and a position loop, which can precisely adjust the motor's operating state according to the characteristics of the rubber compound and the mixing ratio requirements.

[0028] 8. The present invention has a high-precision flow sensor installed near the outlet of the metering pump on the conveying pipe A and the conveying pipe B, which can monitor the flow rate of the rubber material in real time. The flow sensor adopts an electromagnetic or ultrasonic flow sensor. Its working principle is to accurately calculate the flow rate of the rubber material by measuring the changes in electromagnetic induction or ultrasonic signals generated when the fluid flows in the pipe. The measurement accuracy of the sensor can reach ±0.5%, which can provide accurate flow feedback information for proportion control.

[0029] 9. The present invention has a pressure sensor installed in the waveform mixing tube to monitor the pressure during the conveying process of the rubber material. When the viscosity of the rubber material changes or the pipeline is blocked, the pressure will change. The pressure sensor will feed back the pressure signal to the automatic control system in the control cabinet. The pressure sensor adopts the strain gauge or capacitive principle to convert the pressure signal into an electrical signal, ensuring that the pressure of the rubber material during the conveying process is within a safe and stable range.

[0030] 10、The control cabinet of the present application is installed with an automatic control system, which uses a microcontroller (MCU) or a programmable logic controller (PLC) as the core controller, receives signals from the flow sensor and the pressure sensor, calculates the required speed instruction of the mixing motor according to the preset rubber compound ratio and flow parameters, and sends the instruction to the motor driver to realize closed-loop control of the rubber compound flow. Meanwhile, the controller can automatically adjust the control algorithm according to the different characteristics of the rubber compound and environmental parameters to ensure the accuracy of the ratio and the stability of the system.

[0031] 11、The automatic control system in the control cabinet calculates the required flow values of the two components of rubber A and rubber B according to the preset rubber compound ratio. Taking a 3:1 rubber compound ratio required by a certain splicing process of a wind tower drum as an example, the automatic control system will convert this ratio into the speed control instruction of the metering pump on the material conveying pipe A and the material conveying pipe B. After receiving the instruction, the metering pump motor accurately adjusts the speed so that the A component rubber compound is output at a set flow of 3Q1 and the B component rubber compound is output at a flow of Q1.

[0032] 12、The present application adopts a dynamic adjustment mechanism. The online flow monitoring sensor equipped in the automatic control system in the control cabinet monitors the flow of the rubber compound in real time. When the flow sensors in the material conveying pipe A and the material conveying pipe B detect a deviation between the actual flow and the preset flow, for example, due to the instantaneous change of the viscosity of the rubber compound, the flow sensor will immediately feed back the data to the automatic control system, which quickly analyzes and processes the data and issues an instruction to fine-tune the speed of the metering pump motor to increase the output flow of the A component rubber compound, ensuring that the A and B component rubber compounds are always delivered in a 3:1 ratio.

[0033] 13、The present application has self-adaptive adjustment capability. Considering the complex working conditions at the prefabricated component manufacturing site, when environmental temperature, humidity and other factors change, affecting the viscosity and flowability of the rubber compound, the viscosity sensor, temperature sensor and other sensors in the wave-shaped mixing pipe will transmit data to the automatic control system, which automatically adjusts the working parameters of the metering pumps on the material conveying pipe A and the material conveying pipe B through the automatic control system in the control cabinet to ensure accurate rubber compound ratio under different working conditions.

[0034] 14、The control cabinet of the present application is installed with an automatic control system, which processes and analyzes various sensor data such as flow, pressure, temperature, etc. The operator can real-time view the flow, ratio, equipment running status and other information of the rubber compound through the human-machine interface on the control cabinet. Meanwhile, the automatic control system also has data storage function, which can record historical data for subsequent production traceability and quality analysis.

[0035] 15、The present application is provided with multiple security mechanisms, when detecting abnormal fluctuations in traffic beyond the allowed range, motor overload and other conditions, immediately start the emergency brake program, close the metering pump and electric butterfly valve, to avoid the quality problems and equipment damage caused by out of control.

[0036] 16、The glue machine in the application can provide strong compressed air to remove dust, moisture and impurities on the surface to be glued, improve the adhesion of the glue and the surface to be glued when performing the blowing and gluing tasks; when the gluing task is completed, the strong compressed air is converted through the valve and enters the dynamic mixer and static mixer, pushing all the glue out of the equipment quickly from the discharge regulator, completing the self-cleaning process. Prevent the glue from solidifying in the traveling gluing unit, difficult to discharge, and can avoid using harmful solvents such as xylene and ethyl acetate to clean the equipment.
