[0002] The pellet drying mechanism of the injection molding machine is an important component in the injection molding process. It is used to remove moisture from the raw material pellets to ensure the quality and stability of the pellets during the molding process. The dryer is usually composed of a heater, a fan and a hopper.

[0022] When implementing: Figure 1-6 As shown, a particle drying mechanism of an injection molding machine comprises: an injection molding machine body 1, a first discharge port 2, a drying chamber 4, a stirring mechanism 7 and a water vapor exhaust mechanism 8.

At the same time, during use, the water droplets condensed by the water vapor are discharged through the water vapor discharge mechanism 8 to avoid excessive water vapor in the drying bin 4 and prevent it from being in a humid state, thereby improving the drying efficiency. At the same time, when the particles are dried, the dried particles are taken out through the second discharge port 6.

[0023] The heating mechanism 5 includes a heat conductive block 51, a first connecting block 52, a bolt 53 and a heater 54. Two heat conductive blocks 51 are symmetrically arranged on the side of the drying chamber 4. The sides of the two heat conductive blocks 51 are symmetrically arranged with first connecting blocks 52. The two first connecting blocks 52 are threadedly connected by bolts 53. A heater 54 is arranged on the side of the heat conductive block 51. When the device is in use, the two first connecting blocks 52 are connected by bolts 53, and the heat conductive block 51 is connected to the side of the drying chamber 4. During use, the heater 54 is started to heat the heat conductive block 51, and the heat is transferred to the inside of the drying chamber 4 through the heat conductive block 51.

[0024] The stirring mechanism 7 includes a dryer 71, a driving motor 72, a connecting column 73 and a stirring rod 74. The dryer 71 is arranged on the inner side of the drying bin 4, and the driving motor 72 is arranged on the upper end of the dryer 71. The output shaft of the driving motor 72 is connected to the connecting column 73, and the stirring rod 74 is arranged at equal angles on the side of the connecting column 73. When the device is in use, the driving motor 72 is started, and the connecting column 73 is driven by the driving motor 72 to rotate. During the rotation of the connecting column 73, the stirring rod 74 is driven to stir the particles to avoid accumulation of particles that cannot be completely dried. At the same time, the dryer 71 is started to dry the particles from the bottom of the drying bin 4 to improve the drying efficiency.

[0025] Circular holes 75 are symmetrically provided on the side of the stirring rod 74, and a scraper 76 is connected to the side of the stirring rod 74 at the lower end. A second connecting block 77 is embedded on the upper end of the drying chamber 4, and the second connecting block 77 is rotatably connected to the connecting column 73. When the device is in use, the circular hole 75 reduces the resistance to the rotation of the stirring rod 74 during use, thereby saving energy.

[0026] The connecting column 73 is rotatably connected to the side with a filter 78, which is arranged between the driving motor 72 and the stirring rod 74. The filter 78 is fixedly connected to the inner wall of the drying bin 4. When the device is in use, the filter is arranged to facilitate the dryer 71 to dry the particles from the bottom of the drying bin 4, thereby improving the drying efficiency.

[0027] The water vapor exhaust mechanism 8 includes a water guide groove 81, a rotating rod 82, a rubber plate 83 and a guide plate 84. The water guide grooves 81 are opened on both sides of the drying chamber 4. The inner sides of the two water guide grooves 81 are rotatably connected to the rotating rods 82. The rubber plates 83 are arranged at equal angles on the sides of the rotating rods 82. The inner side walls of the water guide grooves 81 are connected to the guide plates 84. The guide plates 84 are arranged at the upper end. When the device is in use, when drying is carried out inside the drying chamber 4, water vapor rises. Since the upper end of the drying chamber 4 is arranged at an angle, the water vapor The water droplets condensed from the air flow to the inner side of the water guide groove 81 through the upper side wall inside the drying chamber 4, and are guided to the side of the rotating rod 82 by the guide plate 84, and are blocked by the rubber plate 83. When the weight of the water droplets exceeds the friction between the rubber plate 83 and the inner side wall of the water guide groove 81, the rubber plate 83 rotates through the rotating rod 82, and the water droplets are discharged through the water guide groove 81. At the same time, the rubber plate 83 rotates through the rotating rod 82 to re-block the water guide groove 81, thereby avoiding heat loss while discharging water vapor, thereby improving the drying efficiency.

[0028] When the utility model is used, the injection molding is first performed through the injection molding machine body 1, and then the injection-molded particles are transported to the inside of the drying bin 4 through the first discharge port 2;

[0029] When the injection-molded particles reach the drying chamber 4, the heater 54 is started to heat the heat-conducting block 51, and the heat is transferred to the drying chamber 4 through the heat-conducting block 51 to dry the particles.

[0030] At the same time, the driving motor 72 is started, and the connecting column 73 is driven to rotate by the driving motor 72. During the rotation of the connecting column 73, the stirring rod 74 is driven to stir the particles to avoid the accumulation of particles and the inability to be completely dried. At the same time, the dryer 71 is started to dry the particles from the bottom of the drying bin 4 to improve the drying efficiency. The circular hole 75 provided during the stirring process reduces the resistance of the stirring rod 74 to the rotation during use, thereby saving energy. The provided filter screen facilitates the dryer 71 to dry the particles from the bottom of the drying bin 4 to improve the drying efficiency.

[0031] When drying is carried out inside the drying chamber 4, water vapor rises. Since the upper end of the drying chamber 4 is arranged at an angle, water droplets condensed from the water vapor flow through the side wall of the upper end of the drying chamber 4 to the inner side of the water guide groove 81, and the water droplets are guided to the side of the rotating rod 82 by the guide plate 84 and blocked by the rubber plate 83. When the weight of the water droplets exceeds the friction between the rubber plate 83 and the inner side wall of the water guide groove 81, the rubber plate 83 rotates through the rotating rod 82. At this time, the water droplets are discharged through the water guide groove 81. At the same time, the rubber plate 83 rotates through the rotating rod 82 to re-block the water guide groove 81, thereby avoiding heat loss while discharging water vapor, thereby improving the drying efficiency.
