[0001] This utility model relates to the field of melting equipment technology, specifically a fast-start spray-type melting machine. Background Technology
[0002] A hot melt glue machine is a device that heats and melts solid hot melt glue particles, then pumps them to a glue gun for precise glue spraying. It is widely used in production fields that require rapid bonding, such as packaging, building materials, and electronic assembly. Traditional hot melt glue machines mostly adopt a single melting chamber heating structure, which requires waiting for all glue particles in the chamber to completely melt before starting glue spraying. The start-up time is generally as long as 15-30 minutes, resulting in low production efficiency and high energy consumption.
[0003] Therefore, it is necessary to propose a fast-start spray adhesive melting machine to solve the above problems. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0014] Example 1: This Example 1 provides a quick-start spray adhesive melting machine, which is a direct improvement on existing melting equipment. It has a unique structure. Please refer to [link / reference]. Figure 1-5As shown, the assembly includes a glue melting tank 1, a control panel 15, a glue pump 16, a glue gun, and a glue spraying box 12. The glue melting tank 1 is an integral load-bearing structure, welded from 304 stainless steel plate, with external dimensions of 800mm (length) × 600mm (width) × 1000mm (height) and a wall thickness of 5mm. It possesses corrosion resistance and high strength characteristics. The glue melting tank 1 has symmetrical inspection ports (opening size 400mm × 500mm) on both sides, and inspection doors 5 are hinged to the openings. The inspection doors 5 are made of cold-rolled steel plate, stamped and formed, with an electrostatic spray coating (light gray color, 60μm film thickness). A 3mm thick nitrile rubber sealing strip is pasted on the inside to ensure sealing and heat insulation when closed, facilitating later inspection and maintenance of internal components.
[0015] The top of the melting tank 1 has a feeding port (opening size 300mm×150mm) in the center. A sealing plate 2 is hinged to the feeding port by a damping hinge. The sealing plate 2 is made of 2mm thick 304 stainless steel plate, and the edges are inlaid with 5mm thick silicone rubber sealing rings. When closed, it can completely block the feeding port, reducing heat loss and glue mist overflow during the melting process. The melting tank 1 is fixedly installed with a melting cylinder 4 by a stainless steel bracket (model ∠50×50×5 angle steel, spacing 300mm). The melting cylinder 4 is made of 304 stainless steel plate welded and formed (thermal conductivity 16.2W / (m·K)), with a total height of 700mm, including the upper melting chamber 6, the lower glue collection chamber 8 and the conical transition section between the two.
[0016] The melting chamber 6 is a rectangular structure, 300mm long, 150mm wide, and 400mm high, used to hold the glue particles to be melted. Heating wire I9 is spirally wound around its outer side. Heating wire I9 is made of Cr20Ni80 nickel-chromium alloy wire (3mm diameter, resistivity 1.09Ω·mm² / m), with a total length of 8m and a power of 2000W. It is fixed by a high-temperature resistant ceramic insulator (model ZA-3), with a spiral spacing of 50mm to ensure uniform heating of the glue particles in the melting chamber 6. The collecting chamber 8 is a rectangular structure, 150mm long, 75mm wide, and 300mm high, used to collect the molten glue. Heating wire II10 is spirally wound around its outer side. Heating wire II10 is made of the same model Cr20Ni80 nickel-chromium alloy wire (2.5mm diameter), with a total length of 5m and a power of 1500W. The spiral spacing is 40mm, which can maintain the glue in the collecting chamber 8 in a molten state (temperature stable at 180±5℃).
[0017] The upper end diameter of the conical transition section matches the melting cavity 6, and the lower end diameter matches the collecting cavity 8. The height is 100mm and the taper is 30°. A slug 7 is fixedly installed in the transition section by bolts. The slug 7 is made of 316 stainless steel plate (thickness 8mm, corrosion resistance is better than 304 stainless steel). There are 40 circular slug holes (hole diameter 2mm, hole spacing 15mm) evenly distributed on it, which only allow the molten glue to pass through and prevent unmelted glue particles from directly entering the collecting cavity 8.
[0018] The outer side of the glue-melting cylinder 4 is fitted with an insulation shell 3. The insulation shell 3 adopts a double-layer structure. The inner layer is 50mm thick aluminum silicate insulation cotton (thermal conductivity 0.03W / (m·K), temperature resistance 300℃), and the outer layer is 0.5mm thick aluminum foil reflective layer, which can effectively reduce the heat loss of the glue-melting cylinder 4. The inner wall of the glue-collecting cavity 8 is fixedly installed with a liquid level gauge 11 through a flange. The liquid level gauge 11 is a capacitive liquid level sensor (model CYW-100, measuring range 0-200mm, accuracy ±1mm, output 4-20mA signal). Its detection end extends 10mm into the glue-collecting cavity 8, which can monitor the liquid level of the glue in the cavity in real time.
[0019] The glue melting box 1 and the glue spraying box 12 are fixedly connected by M10 stainless steel bolts (200mm spacing). The glue spraying box 12 is made of the same 304 stainless steel plate as the glue melting box 1, and its external dimensions are 600mm long × 600mm wide × 800mm high. The front side of the glue spraying box 12 has an operation port (500mm × 600mm in size), and the opening is hinged to a box door 13. The box door 13 adopts a combination structure of double-layer hollow glass (5mm thick) and stainless steel frame, which facilitates observation of the glue spraying status inside, and also has heat insulation.
[0020] A partition 14, made of 3mm thick 304 stainless steel, is welded and fixed inside the glue spraying box 12, dividing the box into upper and lower chambers (upper chamber height 500mm, lower chamber height 300mm). The upper chamber is the glue spraying area, where a glue gun (model JQ-200, nozzle diameter 1.5mm, working pressure 0.3-0.6MPa) is fixedly installed via an adjustable bracket (adjustment range 0-300mm). The glue gun is connected to the glue collection chamber 8 via a φ15mm stainless steel corrugated pipe (pressure resistant 1MPa). Symmetrical through holes (diameter 120mm) are opened on both sides of the upper chamber, and a cooling fan 17 (model SF-120, air volume 300m³ / h, speed 1450r / min, power 40W) is fixedly installed in the through holes. The two fans are arranged diagonally to form convection, which can exhaust the glue mist and heat generated by the glue spraying and maintain the temperature inside the chamber ≤50℃.
[0021] The lower chamber is fixedly installed with a glue pump 16 by a shock-absorbing pad (5mm thick nitrile rubber). The glue pump 16 is a gear-type hot melt glue pump (model RB-15, flow rate 15L / h, working pressure 0.8MPa, speed 300r / min, power 750W). Its input end is connected to the bottom of the glue collection chamber 8 (10mm from the bottom) through a φ20mm stainless steel hard pipe, and its output end is connected to the glue gun through the aforementioned φ15mm corrugated pipe to ensure stable delivery of glue.
[0022] The control panel 15 is embedded in the upper front part of the glue melting tank 1 (300mm×200mm). It integrates a PLC controller (Siemens S7-200 SMART SR40, processing speed 0.15μs / instruction), a relay module (MY2N-J), and a temperature control module (RKC CD901, temperature control accuracy ±1℃). The panel surface is equipped with a 7-inch touch screen (Weintek TK6071IP), an emergency stop button (LA39-11ZS), and indicator lights. It can realize the linkage control of heating wire I9, heating wire II10 (temperature setting range 50-250℃), liquid level gauge 11 (liquid level threshold can be set), glue pump 16 (start / stop and speed adjustment), and cooling fan 17.
[0023] Working principle: During use, open the sealing plate 2 and pour EVA hot melt adhesive granules (melting point 120-150℃) with a particle size of 3-5mm into the melting chamber 6 (maximum capacity approximately 19.6L), then close the sealing plate 2. Set the target temperature of the melting chamber 6 to 160℃ and the target temperature of the collecting chamber 8 to 180℃ via the control panel 15, and activate heating wires I9 and II10. The adhesive granules in the melting chamber 6 are heated by heating wire I9, and the outer granules melt first (initial adhesive solution is generated in approximately 3-5 minutes). The molten adhesive solution flows into the collecting chamber 8 through the drain hole of the perforator plate 7. The level gauge 11 monitors the liquid level in the collecting chamber 8 in real time. When the liquid level reaches a preset threshold (e.g., 100mm, corresponding to a capacity of approximately 1.77L), the control panel 15 automatically starts the glue pump 16. The glue pump delivers the glue from the glue collection chamber 8 to the glue gun, which sprays it out through the glue gun nozzle (the amount of glue sprayed can be adjusted by the glue pump speed, ranging from 0.5-15g / s). If the glue storage in the glue collection chamber 8 is sufficient (e.g., liquid level ≥ 150mm), the control panel 15 can automatically cut off the power to the heating wire I9, leaving only the heating wire II10 to maintain the temperature of the glue collection chamber 8, thus reducing energy consumption. When the liquid level is below 50mm, the heating wire I9 is automatically restarted to ensure a continuous supply of glue.
[0024] Example 2: Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the bottoms of the melt glue tank 1 and the spray glue tank 12 are fixedly installed on the base plate 22 by M12 expansion bolts (300mm spacing); the base plate 22 is made of Q235 steel plate (10mm thickness, 235MPa yield strength) cut and formed, with dimensions of 1500mm in length × 800mm in width, and the bottom is treated with sandblasting and rust removal and then sprayed with anti-rust paint (dry film thickness 80μm); four universal wheels 18 and four limiting components (100mm spacing between adjacent universal wheels and limiting components) are fixedly installed at the four corners of the bottom of the base plate 22 (arranged in a rectangular array). The casters 18 are polyurethane casters (model TPR-150, wheel diameter 150mm, single wheel load capacity 300kg) to ensure flexible movement of the equipment (360° steering angle) and stable braking; the limiting components include a screw barrel 19, a screw rod 20, and an anti-slip pad 21: the screw barrel 19 is an internally threaded barrel (M20×2, length 100mm) machined from 45# steel, which is fixed to the bottom of the base plate 22 by welding; the screw rod 20 is a matching externally threaded screw rod (M20×2, length 150mm). The upper end is equipped with a hexagonal adjustment head (30mm distance between sides) for easy height adjustment with a wrench; the lower end of the screw 20 is bonded with an anti-slip pad 21 by epoxy resin. The anti-slip pad 21 is a 50mm×50mm×10mm nitrile rubber pad (Shore hardness 60±5A) with a diamond-shaped anti-slip texture (texture depth 1mm). When the equipment is moved to the target position, tighten the screw 20 to make the anti-slip pad 21 fit against the ground (contact pressure ≥0.5MPa), which can effectively prevent the equipment from slipping.
