如果說雙組份打膠機(jī)是中空玻璃的非常后一道防線，那么丁基膠涂布機(jī)就是第一道防線。在中空玻璃的生產(chǎn)工藝中，鋁間隔框兩側(cè)需要先涂布一層丁基熱熔膠，這層膠作為一道密封，與后續(xù)的二道密封膠共同構(gòu)成中空玻璃完整的密封體系。承擔(dān)這道工序的設(shè)備，便是丁基膠涂布機(jī)。

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.

丁基膠涂布機(jī)是加工中空玻璃的專用設(shè)備，其核心功能是將丁基膠加熱熔融后，均勻地涂布在中空玻璃鋁間隔框的兩側(cè)。丁基膠在常溫下呈固態(tài)，建議經(jīng)過加熱才能變成具有流動(dòng)性的熔融狀態(tài)，因此加熱系統(tǒng)是丁基膠涂布機(jī)的核心部件之一。設(shè)備通常配備膠缸加熱和膠頭加熱兩套溫控系統(tǒng)，膠缸加熱溫度一般控制在110°C±15°C，膠頭加熱溫度控制在140°C±15°C。部分先進(jìn)設(shè)備還具備定時(shí)開關(guān)機(jī)功能，可以預(yù)設(shè)加熱時(shí)間，既節(jié)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.

從設(shè)備結(jié)構(gòu)來看，丁基膠涂布機(jī)主要分為立式和臥式兩種類型。以LJT03型立式丁基膠涂布機(jī)為例，其放膠口設(shè)置在機(jī)器上端，丁基膠內(nèi)部微小的空氣在加熱后上升，通過膠缸和活塞的合理配合將空氣排出，但絕不漏膠。壓膠頭采用浮動(dòng)式軟連接設(shè)計(jì)，能夠自動(dòng)導(dǎo)向，使膠缸和活塞周邊受力均勻，有效克服了臥式膠缸底部局部嚴(yán)重磨損的設(shè)計(jì)缺陷。在動(dòng)力系統(tǒng)方面，立式設(shè)備采用大液壓站結(jié)構(gòu)并新增蓄能器，能夠提供穩(wěn)定的壓力，解決了使用氣液增壓裝置換膠速度慢和壓力不穩(wěn)定的問題。

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.

在自動(dòng)化控制方面，現(xiàn)代丁基膠涂布機(jī)普遍采用PLC或PC控制系統(tǒng)。設(shè)備運(yùn)行過程中，操作人員將鋁間隔框放在傳送帶上，人工扶持間隔框隨傳送帶行進(jìn)。當(dāng)間隔框通過傳感器時(shí)，傳送壓輪及打膠閥按設(shè)定程序自動(dòng)動(dòng)作——?dú)怦R達(dá)動(dòng)作、壓輪壓下，壓送鋁間隔條行進(jìn)。當(dāng)間隔條到達(dá)打膠頭時(shí)開始涂膠，離開打膠頭時(shí)自動(dòng)停止噴膠。整個(gè)過程中，定位、傳送、涂膠均可自動(dòng)完成。這種人機(jī)協(xié)作的半自動(dòng)工作模式既保證了涂膠質(zhì)量，又降低了操作難度。

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.

在技術(shù)參數(shù)方面，主流丁基膠涂布機(jī)的膠缸直徑多為195mm，容量較大，可避免頻繁加膠。輸送速度通常在8至40m/min之間可調(diào)，膠頭可調(diào)范圍為6至20mm。擠膠壓力一般為8至15MPa，工作氣壓要求0.5至0.8MPa。設(shè)備總功率約1.8至3.2KW，外形尺寸約為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.

丁基膠涂布機(jī)在中空玻璃生產(chǎn)線中處于承上啟下的關(guān)鍵位置——在鋁框灌裝分子篩之后、合片之前完成涂膠。正因如此，它被業(yè)內(nèi)公認(rèn)為生產(chǎn)槽鋁式中空玻璃的必備設(shè)備和非常關(guān)鍵設(shè)備之一。隨著技術(shù)的不斷進(jìn)步，丁基膠涂布機(jī)在控溫精度、涂膠均勻性、操作便捷性等方面持續(xù)提升，為中空玻璃產(chǎn)品的質(zhì)量和效率提供了堅(jiān)實(shí)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.
