[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-3 A butyl sealant coating machine for insulating glass is provided, the butyl sealant coating machine for insulating glass includes a coating die head, and further includes: A closed glue tank 1 includes a tank body 11 and a lid 12. The lid 12 is detachably installed on the tank body 11. The outer surface of the tank body 11 is covered with a double-layer heat insulation sleeve 111. A spiral stirrer is integrated on the lid 12. The coating die head is connected to the glue outlet at the bottom of the tank body 11 via a flange. The die head gap adjustment range on the coating die head is 0.5-2mm. In application, the sealing design of the lid 12 effectively isolates air, prevents butyl rubber from oxidizing and forming a skin at high temperature, and ensures the stability of the glue. At the same time, the double-layer heat insulation sleeve 111 design can reduce external temperature interference and maintain the uniformity of the internal temperature of the tank body 11. The constant temperature control system includes a PID temperature controller 201 (set temperature range 120-150℃, accuracy ±1℃) installed on the double-layer heat insulation sleeve 111, a semiconductor heating element array 202 (single semiconductor heating element power 200W), and temperature sensors distributed on the inner wall of the tank 11 at different heights. The semiconductor heating element array 202 and the temperature sensors are electrically connected to the PID temperature controller 201 via wires. In application, the cooperation between the PID temperature controller 201 and the semiconductor heating element array 202 can achieve precise temperature control and avoid viscosity changes of the colloid due to temperature fluctuations. At the same time, combined with the temperature sensors at different heights, the temperature at different positions inside the tank 11 can be monitored in real time to ensure uniform heating. The vacuum degassing mechanism includes a vacuum pump 301 mounted on the tank cover 12 via a fixed base. A delivery pipe 302 is installed on the vacuum pump 301, passing through the tank cover 12 and connecting to the tank body 11. A pressure gauge 303 (range -0.1-0 MPa) is installed on the inlet pipe of the delivery pipe 302. An automatic pressure relief valve 304 (safe pressure threshold 0.08 MPa) is installed on the tank cover 12 and is connected to the tank body 11. In application, the combined design of the vacuum pump 301 and the automatic pressure relief valve 304 can quickly remove colloidal bubbles, improving coating sealing. Simultaneously, the pressure gauge 303 allows for real-time monitoring of the pressure inside the tank body 11, ensuring operational safety.

[0020] Reference Figure 2 and Figure 3 The bottom of the can lid 12 has an integrally formed external threaded cylinder 121 that is threadedly connected to the top of the inner cavity of the can body 11. The can lid 12 can be detachably installed on the can body 11 through the external threaded cylinder 121. In application, the can lid 12 and the can body 11 are threadedly connected, which makes disassembly convenient and provides strong sealing, making it easy to clean and maintain the closed plastic can 1.

[0021] Reference Figure 2 and Figure 3 The tank body 11 has an internal sandwich cavity 112. The semiconductor heating element array 202 is installed in the sandwich cavity 112 and the sandwich cavity 112 is filled with ceramic fiber insulation material. The semiconductor heating element array 202 consists of 6-8 semiconductor heating elements equidistantly arranged along the axial / circumferential direction of the tank body 11. In application, the semiconductor heating elements are built into the sandwich cavity 112 and can directly heat the tank wall of the tank body 11 to improve heating efficiency and reduce energy consumption. At the same time, the 6-8 semiconductor heating elements are evenly distributed, which can eliminate the risk of local overheating and extend the service life of the colloid.

[0022] Reference Figure 2 and Figure 3 The spiral stirrer includes a variable diameter spiral blade 123 that is vertically and rotatably mounted on a tank cover 12. A servo motor 122 is mounted on the tank cover 12, and the output shaft of the servo motor 122 is connected to one end of the variable diameter spiral blade 123. The blade spacing of the variable diameter spiral blade 123 gradually decreases along its axial direction (from 30mm at the top to 10mm at the bottom). In application, the design of decreasing blade spacing generates gradient shear force during stirring, which efficiently mixes colloids and prevents sedimentation and stratification. At the same time, the servo motor 122 drives the speed, which is adjustable, and can adapt to the stirring needs of colloids of different viscosities, avoiding excessive shearing that could cause colloid denaturation.

[0023] Reference Figure 1 and Figure 2The outer surface of the can lid 12 is equipped with operating rods 124 that are equidistantly arranged along the axial direction of the can lid 12 and used for applying force. In application, the multiple force application points make it easy to manually twist the can lid 12, reducing the intensity of operation and improving the efficiency of disassembly and assembly.

[0024] The working principle of this utility model is as follows: Preparation: Turn the operating lever 124 to open the can lid 12, inject an appropriate amount (80% of the volume of the can 11) of butyl rubber into the can 11, then start the PID temperature controller 201, set the temperature to 130℃, and heat until the viscosity of the colloid reaches 5000±200mPa·s. Stirring and degassing: Turn on the servo motor 122 and stir at a certain speed (30r / min) for a period of time (10 minutes). Then start the vacuum pump 301, evacuate to -0.08MPa and maintain it for a period of time (5 minutes). Observe the pressure display 303 and turn it off after it stabilizes. Coating operation: Adjust the glue dispensing speed to 2-3m / min through the pressure valve of the coating die head, and pass the insulating glass at a uniform speed with the edge 5-10mm away from the die head. The glue layer thickness is controlled to be 0.4±0.05mm. Maintenance phase: After shutdown, open the automatic pressure relief valve 304 to release residual pressure, remove the can cover 12 to clean residual colloid, and at the same time check the resistance value of the semiconductor heating element (standard value 20±2Ω) every month and replace the abnormal semiconductor heating element.
