[0020] This utility model provides a hot melt adhesive coating device for polyester flat strips.

[0021] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a cylinder 1, a rotating rod 2 rotatably connected to the inner surface of the end of the cylinder 1, an agitator 3 fixedly connected to one end of the rotating rod 2, a rotating tube 4 rotatably sleeved on the outside of the rotating rod 2, a fixed frame 5 fixedly sleeved on the outside of the rotating tube 4, and a piston plate 6 slidably sleeved on the outside of the rotating tube 4. The fixed frame 5 is fixedly connected to the inner wall of the cylinder 1. A heating component is provided inside the agitator 3. A rotating component 8 that drives the rotating rod 2 to rotate is provided on the cylinder 1, and a sliding component 9 that drives the piston plate 6 to move axially along the rotating tube 4. Specifically, a sealing ring is installed at the end of the rotating rod 2 to ensure that the hot melt adhesive does not leak from the gap between the rotating rod 2 and the rotating tube 4; a sealing ring is installed on the inner wall of the piston plate 6 to ensure that the hot melt adhesive does not leak from the gap between the piston plate 6 and the rotating tube 4.

[0022] Please see Figure 4 The agitator 3 includes an outer ring 31 and an inner plate 32. A fan blade plate 33 arranged in a circular array is fixedly connected between the outer ring 31 and the inner plate 32. The inner plate 32 is fixedly connected to one end of the rotating rod 2.

[0023] Please see Figure 4 The heating assembly includes a heating rod 10. The fan blade 33 has an installation groove 1 inside, and the heating rod 10 is installed in the installation groove 1. The rotating rod 2 has an installation groove 2 inside. One end of the heating rod 10 is electrically connected to a wire 11. The wire 11 is located inside the installation groove 2, and one end of the wire 11 is electrically connected to a dual-channel electric slip ring 12. The rotating part of the dual-channel electric slip ring 12 is fixedly connected to the opening of the groove 2, and the stationary part of the dual-channel electric slip ring 12 is installed on the inner wall of the cylinder 1. Specifically, the heating element inside the heating rod 10, such as a resistance wire, receives current through the wire 11, causing the resistance wire to heat up and convert electrical energy into heat energy, thereby heating the hot melt adhesive. The heating rod 10 is electrically connected to the wire 11, and the wire 11 is electrically connected to the dual-channel slip ring 12. The dual-channel slip ring 12 is electrically connected to the power supply via an external wire. To improve the safety of the heating rod 10, a thermostat or fuse needs to be installed on the external wire of the dual-channel slip ring 12. When the temperature of the heating rod 10 exceeds the set value, the power supply is automatically cut off to prevent safety accidents caused by overheating. The heating rod 10 and its wire 11 are treated with high-quality insulating materials for double insulation to ensure that no leakage accidents occur during operation. Specifically, the heating rod 10, the wire 11, the dual-channel slip ring 12, the heating resistor or the fuse are all existing technology equipment and structures, and their specific forms, usage methods and installation methods are all existing technology means, which will not be described in detail in this application.

[0024] Please see Figure 2 and Figure 3 The sliding component 9 includes a threaded rod 91, a threaded sleeve 92 is threadedly fitted on the outside of the threaded rod 91, a triangular stabilizer 93 is fixedly connected to one end of the threaded sleeve 92, the triangular stabilizer 93 is slidably fitted on the outside of the rotating tube 4, and one side of the triangular stabilizer 93 is fixedly connected to the side wall of the piston plate 6, the end of the threaded rod 91 away from the threaded sleeve 92 is rotatably connected to the inner surface of the end of the cylinder 1, a servo motor 94 is installed on the cylinder 1, and the output shaft of the servo motor 94 is fixedly connected to one end of the threaded rod 91; Specifically, the servo motor 94 is electrically connected to the power supply. The model of the servo motor 94 is not limited, but depends on the compatible equipment. The triangular stabilizer 93 is used to increase the force range of the piston plate 6, thereby avoiding the impact on the stability and linear sliding of the piston plate 6 due to the threaded sleeve 92 being set on the off-axis of the piston plate 6. The triangular stabilizer 93 has a through hole at the corresponding position of the rotating tube 4. The triangular stabilizer 93 is slidably sleeved on the outside of the rotating tube 4 through the through hole. With the cooperation of the triangular stabilizer 93 and the rotating tube 4, the threaded sleeve 92 can slide stably and cannot rotate on its own. Specifically, the piston plate 6 is an existing technology device and structure. Its specific form, usage and installation method are all existing technical means, and this application will not elaborate on them. The piston plate 6 is mainly used to push the hot melt adhesive in the cylinder 1 to move to the discharge pipe 13 and to discharge the hot melt adhesive from the discharge pipe 13.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotating assembly 8 includes a large gear 81 and a small gear 82 that mesh with each other. The small gear 82 is fixedly sleeved on the outside of the rotating rod 2, and the large gear 81 is fixedly sleeved on one end of the threaded rod 91. Specifically, the number of teeth on the large gear 81 is more than twice the number of teeth on the small gear 82, so that the stirring component 3 will rotate quickly when the piston plate 6 slowly pushes the hot melt adhesive.

[0026] Please see Figure 2 and Figure 3 The cylinder 1 includes a cylindrical cylinder 101. One end of the cylindrical cylinder 101 is provided with an external thread, and the cylindrical cylinder 101 is threaded with an internal threaded tube through the external thread. One end of the internal threaded tube is fixedly connected to a conical cylinder 102. The conical cylinder 102 is located on one side of the cylindrical cylinder 101 and has a frustum-shaped stirring groove. The stirring element 3 is located inside the stirring groove. Specifically, due to the obstruction of the agitator 3, the piston plate 6 will be pushed to the agitator 3 and stop. The hot melt adhesive inside the agitator 3 will not be discharged. However, the space of the conical cylinder 102 is limited, and the hot melt adhesive remaining in the conical cylinder 102 is negligible. The hot melt adhesive inside the conical cylinder 102 can be cleaned or removed by disassembling the conical cylinder 102.

[0027] Please see Figure 2 A sealing groove is provided at one of the opposite ends of the conical cylinder 102 and the cylindrical cylinder 101, and a sealing ring is provided between the two sealing grooves.

[0028] Please see Figure 1 and Figure 2 The outer side of the cylindrical tube 101 is fixedly connected to the feed pipe 7, and one end of the conical tube 102 is fixedly connected to the discharge pipe 13.

[0029] Working principle: Hot melt adhesive is fed into the cylinder 1 through the feed pipe 7. The heating rod 10 in the heating component is connected to the dual-channel electric slip ring 12 through the wire 11. When the rotating rod 2 rotates, the dual-channel electric slip ring 12 ensures a stable power supply to the heating rod 10, so as to achieve uniform heating of the hot melt adhesive. At the same time, the fan blade 33 in the stirring component 3 rotates under the drive of the rotating rod 2 to stir the hot melt adhesive, so as to prevent local overheating or uneven melting of the hot melt adhesive during the heating process, and ensure the uniformity of the hot melt adhesive.

[0030] In the rotating assembly 8, the large gear 81 and the small gear 82 mesh with each other, and the servo motor 94 drives the threaded rod 91 to rotate, which in turn drives the threaded sleeve 92 and the piston plate 6 to move axially along the rotating tube 4. The piston plate 6 pushes the hot melt adhesive to move along the rotating tube 4 and discharges the hot melt adhesive through the discharge pipe 13. At the same time, by utilizing the cooperation of the large gear 81 and the small gear 82, the rotating rod 2 moves and rotates together, and the rotating rod 2 drives the stirring component 3 to rotate. The hot melt adhesive maintains a uniform temperature and fluidity during the conveying process, which further ensures the uniformity and stability of the coating effect.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
