Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt composites, in particular to a heating device of a hot-melt composite machine. Background Art

[0002] In the production and application of hot-melt laminating machines, the heating device plays a key role, and its performance directly affects the quality and efficiency of hot-melt lamination. Hot-melt adhesive is solid and non-sticky at room temperature. Heating causes the hot-melt adhesive to reach its melting point, transforming it from a solid state to a liquid state. Liquid hot-melt adhesive has excellent fluidity and viscosity, allowing it to evenly distribute across the surfaces of the laminating materials, providing adhesion for the composite. For example, in the lamination process of leather and fabric, the melted hot-melt adhesive can penetrate the interfiber spaces between the leather and fabric. Once cooled and solidified, it firmly bonds the two materials together.

[0003] However, the heating devices used in hot-melt laminating machines on the market are mostly relatively fixed, so when heating the material, there is a problem of uneven heating. Since the relative distance and angle between the different positions of the material and the heating device remain basically unchanged during the transmission process, the part of the material closer to the heating source receives more heat, while the part farther away receives less heat, and this uneven heating is more obvious.

[0004] Moreover, the existing heating device cannot effectively cover the entire material area. The edge part often does not get enough heat, and the center part may overheat due to excessive heat concentration and cannot be fully heated. This uneven heating directly affects the heating speed and effect. The uneven heating makes it impossible for the hot melt adhesive inside the material to reach the ideal melting state at the same time. In the subsequent compounding process, quality problems such as loose bonding or delamination are likely to occur. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a heating device for a hot melt laminating machine.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A heating device for a hot melt laminating machine includes a bottom box and a heating cabinet fixedly mounted on the bottom box. A heating tray is fixedly mounted in the heating cabinet and hot melt adhesive is stored in the heating tray. A door-shaped movable frame is movably mounted in the heating cabinet above the heating tray via a moving mechanism. A carbon fiber infrared heating lamp is fixedly mounted on the door-shaped movable frame for infrared heating of the hot melt adhesive.

[0008] A sliding frame is movably installed in the bottom box, and a sliding seat is fixedly connected to the top of the sliding frame. The top of the sliding seat slides horizontally into the heating cabinet and is fixedly connected to a heating frame. The heating frame is provided with a resistance heating tube for heating the hot melt adhesive in the heating tray; a hot air blower is also provided in the heating frame below the resistance heating tube, and the hot air blower is adapted to the resistance heating tube.

[0009] A mounting plate is fixedly installed in the bottom box at the rear side of the sliding frame, a driving motor is fixedly installed on the front side of the mounting plate, and an incomplete gear is fixedly sleeved on the output shaft of the driving motor. A plurality of transmission teeth are provided on the top inner wall and the bottom inner wall of the sliding frame, and the incomplete gear is respectively engaged with the transmission teeth on the top inner wall and the bottom inner wall of the sliding frame.

[0010] Furthermore, a transverse sliding hole is provided on the top inner wall of the bottom box, and the sliding seat slides horizontally through the transverse sliding hole.

[0011] Furthermore, a guide slider is fixedly provided at the bottom of the sliding frame, a guide slot is provided on the inner wall of the bottom side of the bottom box, and the guide slider is slidably installed in the guide slot along the horizontal direction.

[0012] Furthermore, the moving mechanism includes an electric telescopic rod fixedly mounted on the inner walls on both sides of the heating cabinet, and the electric telescopic rod is arranged along the front-to-back direction, the output end of the electric telescopic rod is fixedly connected to a movable block, and the movable block is fixedly connected to the outside of the door-shaped movable frame.

[0013] Furthermore, an opening is provided at the upper front portion of the heating cabinet, a cabinet door is hingedly connected to the opening via a hinge, and a door lock is provided on the cabinet door.

[0014] Furthermore, a controller is provided on the front of the bottom box, and the controller is electrically controlled and connected to the drive motor, the electric telescopic rod, the carbon fiber infrared heating lamp tube, the resistance heating tube, and the hot air machine.

[0015] With the above structure, the beneficial effects achieved by the utility model are as follows:

[0016] 1. The heating device of this hot melt laminating machine heats the hot melt adhesive in the heating tray by combining resistance heating of the resistance heating tube and infrared heating of the carbon fiber infrared heating lamp. The heating of the resistance heating tube is used to provide a stable base heat so that the bottom of the hot melt adhesive material can be heated evenly. The infrared heating of the carbon fiber infrared heating lamp radiates the hot melt adhesive material from above, which can quickly penetrate the surface of the material and melt the hot melt adhesive inside more quickly. This combined heating method can greatly improve the heating speed and heating uniformity.

[0017] 2. During the heating process, the heating device of the hot melt laminating machine can extend and retract the electric telescopic rod to allow the carbon fiber infrared heating lamp to radiate heat uniformly from the front and back of the hot melt adhesive material from above. At the same time, the driving motor, the broken gear, the sliding frame, the transmission gear, the sliding frame, the slide seat, the heating frame, the hot air blower and the resistance heating tube can be coordinated to uniformly heat the bottom of the hot melt adhesive material while moving left and right, thus avoiding the problem of uneven heating of the hot melt adhesive material caused by the fixed setting of the existing hot melt laminating machine heating device.

[0018] 3. Moreover, the continuous movement of heating devices such as carbon fiber infrared heating lamps, hot air blowers, and resistance heating tubes can effectively cover the entire hot melt adhesive material area to prevent the edge of the glue material from not getting enough heat, while the center part is prone to overheating due to excessive heat concentration, and other uneven heating situations. This is conducive to ensuring the overall heating speed and effect, and greatly guarantees the smooth use of subsequent compounding;

[0019] In summary, the utility model heats the hot melt adhesive by combining the resistance heating of the resistance heating tube and the infrared heating of the carbon fiber infrared heating lamp. This combined heating method can greatly improve the heating speed and heating uniformity; and during the heating process, the carbon fiber infrared heating lamp can also perform uniform radiation heating on the hot melt adhesive material from the top and back; at the same time, the resistance heating tube can also be moved left and right to uniformly heat the bottom of the hot melt adhesive material, avoiding the problem of uneven heating of the hot melt adhesive material caused by the fixed setting of the existing hot melt laminating machine heating device, which is conducive to ensuring the overall heating speed and effect, and greatly guarantees the smooth use of subsequent lamination.

The output end of the electric telescopic rod 10 is fixedly connected to a movable block 11, and the movable block 11 is fixedly connected to the outside of the door-shaped movable frame 901.

[0029] Among them, an opening 201 is provided on the upper front side of the heating cabinet 2, and a cabinet door 202 is hinged at the opening 201 through a hinge, and a door lock is provided on the cabinet door 202; a controller 15 is provided on the front of the bottom box 1, and the controller 15 is electrically controlled and connected with the drive motor 3, the electric telescopic rod 10, the carbon fiber infrared heating lamp tube 9, the resistance heating tube 702, and the hot air blower 701 respectively.
