如果说双组份打胶机是中空玻璃的非常后一道防线，那么丁基胶涂布机就是第一道防线。在中空玻璃的生产工艺中，铝间隔框两侧需要先涂布一层丁基热熔胶，这层胶作为一道密封，与后续的二道密封胶共同构成中空玻璃完整的密封体系。承担这道工序的设备，便是丁基胶涂布机。

If the two-component gluing machine is the last line of defense for insulating glass, then the butyl rubber coating machine is the first line of defense. In the production process of insulating glass, a layer of butyl hot melt adhesive needs to be applied on both sides of the aluminum spacer frame. This layer of adhesive serves as a seal and together with the subsequent two layers of sealant, forms a complete sealing system for the insulating glass. The equipment responsible for this process is the butyl rubber coating machine.

丁基胶涂布机是加工中空玻璃的专用设备，其核心功能是将丁基胶加热熔融后，均匀地涂布在中空玻璃铝间隔框的两侧。丁基胶在常温下呈固态，建议经过加热才能变成具有流动性的熔融状态，因此加热系统是丁基胶涂布机的核心部件之一。设备通常配备胶缸加热和胶头加热两套温控系统，胶缸加热温度一般控制在110°C±15°C，胶头加热温度控制在140°C±15°C。部分先进设备还具备定时开关机功能，可以预设加热时间，既节能又方便。

The butyl rubber coating machine is a specialized equipment for processing insulating glass. Its core function is to heat and melt the butyl rubber, and evenly coat it on both sides of the aluminum spacer frame of the insulating glass. Butyl rubber is in a solid state at room temperature and must be heated to become a molten state with fluidity. Therefore, the heating system is one of the core components of the butyl rubber coating machine. The equipment is usually equipped with two sets of temperature control systems for heating the rubber cylinder and the rubber head. The heating temperature of the rubber cylinder is generally controlled at 110 ° C ± 15 ° C, and the heating temperature of the rubber head is controlled at 140 ° C ± 15 ° C. Some advanced equipment also has a timed on/off function, which can preset the heating time, which is both energy-saving and convenient.

从设备结构来看，丁基胶涂布机主要分为立式和卧式两种类型。以LJT03型立式丁基胶涂布机为例，其放胶口设置在机器上端，丁基胶内部微小的空气在加热后上升，通过胶缸和活塞的合理配合将空气排出，但绝不漏胶。压胶头采用浮动式软连接设计，能够自动导向，使胶缸和活塞周边受力均匀，有效克服了卧式胶缸底部局部严重磨损的设计缺陷。在动力系统方面，立式设备采用大液压站结构并新增蓄能器，能够提供稳定的压力，解决了使用气液增压装置换胶速度慢和压力不稳定的问题。

From the perspective of equipment structure, butyl rubber coating machines are mainly divided into two types: vertical and horizontal. Taking the LJT03 vertical butyl rubber coating machine as an example, its rubber dispensing port is set at the upper end of the machine. The tiny air inside the butyl rubber rises after heating and is discharged through the reasonable cooperation of the rubber cylinder and piston, but it never leaks the rubber. The pressure head adopts a floating soft connection design, which can automatically guide and evenly distribute the force around the rubber cylinder and piston, effectively overcoming the design defect of severe local wear at the bottom of the horizontal rubber cylinder. In terms of power system, the vertical equipment adopts a large hydraulic station structure and adds an accumulator, which can provide stable pressure and solve the problems of slow rubber changing speed and unstable pressure when using gas-liquid boosting devices.

在自动化控制方面，现代丁基胶涂布机普遍采用PLC或PC控制系统。设备运行过程中，操作人员将铝间隔框放在传送带上，人工扶持间隔框随传送带行进。当间隔框通过传感器时，传送压轮及打胶阀按设定程序自动动作——气马达动作、压轮压下，压送铝间隔条行进。当间隔条到达打胶头时开始涂胶，离开打胶头时自动停止喷胶。整个过程中，定位、传送、涂胶均可自动完成。这种人机协作的半自动工作模式既保证了涂胶质量，又降低了操作难度。

In terms of automation control, modern butyl rubber coating machines commonly use PLC or PC control systems. During the operation of the equipment, the operator places the aluminum spacer frame on the conveyor belt and manually supports the spacer frame to move along with the conveyor belt. When the spacing frame passes through the sensor, the conveying pressure wheel and glue valve automatically move according to the set program - the air motor moves, the pressure wheel presses down, and the aluminum spacing strip moves. When the spacer reaches the glue head, it starts to apply glue, and when it leaves the glue head, it automatically stops spraying glue. Throughout the entire process, positioning, conveying, and gluing can all be automatically completed. This semi-automatic working mode of human-machine collaboration not only ensures the quality of adhesive coating, but also reduces the difficulty of operation.

在技术参数方面，主流丁基胶涂布机的胶缸直径多为195mm，容量较大，可避免频繁加胶。输送速度通常在8至40m/min之间可调，胶头可调范围为6至20mm。挤胶压力一般为8至15MPa，工作气压要求0.5至0.8MPa。设备总功率约1.8至3.2KW，外形尺寸约为3200×700×1050mm。

In terms of technical parameters, the diameter of the glue cylinder of mainstream butyl rubber coating machines is mostly 195mm, with a large capacity, which can avoid frequent glue addition. The conveying speed is usually adjustable between 8 and 40m/min, and the adjustable range of the glue head is 6 to 20mm. The extrusion pressure is generally 8 to 15MPa, and the working pressure requirement is 0.5 to 0.8MPa. The total power of the equipment is about 1.8 to 3.2KW, and the external dimensions are about 3200 × 700 × 1050mm.

丁基胶涂布机在中空玻璃生产线中处于承上启下的关键位置——在铝框灌装分子筛之后、合片之前完成涂胶。正因如此，它被业内公认为生产槽铝式中空玻璃的必备设备和非常关键设备之一。随着技术的不断进步，丁基胶涂布机在控温精度、涂胶均匀性、操作便捷性等方面持续提升，为中空玻璃产品的质量和效率提供了坚实保障。

The butyl rubber coating machine plays a crucial role in the production line of insulating glass, serving as a bridge between the top and the bottom - completing the coating process after filling the aluminum frame with molecular sieves and before laminating. Therefore, it is widely recognized in the industry as an essential equipment and one of the most critical devices for producing trough aluminum insulated glass. With the continuous advancement of technology, the butyl rubber coating machine continues to improve in temperature control accuracy, coating uniformity, and operational convenience, providing a solid guarantee for the quality and efficiency of insulating glass products.
