Description

Technical Field

[0001] The present invention relates to the technical field of glue production and processing, and particularly relates to an integrated glue supply and processing system. Background Art

[0002] Currently, the following technical bottlenecks exist in traditional glue configuration systems:

[0003] Insufficient temperature control: Conventional equipment mostly adopts static heating methods, with a large temperature fluctuation range (usually exceeding ±2°C), unable to achieve dynamic adjustment, resulting in local overheating or cooling of the glue during mixing and storage, affecting the stability of the colloid. Especially for special glues such as epoxy resins and UV glues that are sensitive to temperature, the traditional system is difficult to meet their precise temperature control requirements (such as maintaining within ±0.5°C).

[0004] Poor mixing uniformity: The mechanical stirring system is prone to mechanical vibration (amplitude ≥ 0.1 mm), resulting in an increased internal bubble rate of the glue (> 5%), and the viscosity difference of high-viscosity colloids (such as silica gel) after mixing often exceeds 5%, affecting product consistency. In addition, the glue adheres severely to the surface of the stirring paddle (residual amount > 3%), causing waste of raw materials. Summary of the Invention

[0117] Dynamic Temperature Control Implementation Details of Heating Module 100

[0118] Heating Process:

[0119] Start the central control system (500), and set the target temperature (such as 80°C) and the heating rate (such as 5°C / min) through the human-machine interface;

[0120] The PTC ceramic heating element of the electric heating unit is powered on, and the initial power is 70% of the total power. The output power is adjusted in real time through the PID algorithm;

[0121] Start the centrifugal pump of the circulating water circuit, and control the water flow rate at 2.5 m / s through the frequency converter. The spiral guide vane enhances the turbulence, and the heat exchange efficiency is increased to more than 85%;

[0122] The platinum resistance sensor collects the temperature data of the glue bucket jacket every 0.1 second, and transmits it to the central control system through RS485 to form a closed-loop feedback to ensure that the temperature fluctuation ≤ ±0.3°C.

[0123] Test Data:

[0124] In the heating test of 20L epoxy resin glue, it takes 10 minutes to rise from 25°C to 80°C, the maximum temperature deviation is 0.28°C, and the fluctuation range after reaching the steady state is ±0.15°C;

[0125] Energy Consumption Comparison: Compared with traditional resistance wire heating, the energy saving rate ≥ 25%.

The temperature in the tank returns to the set value (such as 60°C) within 30 minutes, with a fluctuation ≤ ± 0.2°C;

[0146] In a high - temperature environment of 50°C, the vacuum insulation layer effectively isolates external heat, and the temperature in the tank rises ≤ 0.5°C within 24 hours.

[0152] The user sets process parameters through the mobile APP, remotely starts the device and monitors the operating status;

[0153] When the system detects an abnormality (such as over-temperature or glue supply blockage), it automatically pushes an alarm message and triggers shutdown protection.

[0154] Data security and efficiency:

[0155] The AES-256 encryption algorithm ensures the security of transmitted data, and the packet loss rate ≤ 0.01%;

[0156] The cloud server optimizes the glue supply parameters based on historical data, increasing the production efficiency by 15% - 20%.
