[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 The utility model provides a technical solution: a plastic granule softening device, comprising a heating barrel 1, a storage barrel 3 is placed in the heating barrel 1, an air duct 101 is opened on the inner wall of the heating barrel 1, a blast chamber 104 is opened at the bottom of the heating barrel 1, the blast chamber 104 is communicated with the inside of the air duct 101, a blast hole 105 is opened at the center of the bottom of the heating barrel 1, the blast hole 105 is communicated with the inside of the heating barrel 1, a fan 106 is fixedly connected in the blast chamber 104, a ventilation pipe 303 is fixedly connected to the bottom of the storage barrel 3, a plurality of exhaust holes 304 are opened on the ventilation pipe 303, a filter screen is fixedly connected in the exhaust hole 304, a ventilation filter screen 302 is fixedly connected to the outer wall of the storage barrel 3, and an upper cover 201 is arranged above the storage barrel 3.
[0022] In the present embodiment, the upper end of the storage barrel 3 can be closed by the upper cover 201, and the high-temperature air can be blown into the ventilation pipe 303 through the blast hole 105 by starting the fan 106. The high-temperature air will be discharged into the storage barrel 3 through the exhaust hole 304, thereby heating and softening the rubber particles stored in the storage barrel 3. Since the ventilation pipe 303 is erected inside the storage barrel 3, the high-temperature air can be better and more evenly transported to the storage barrel 3, thereby effectively and evenly heating the rubber particles stored in the storage barrel 3. At the same time, the upper end of the storage barrel 3 is blocked by the upper cover 201, and the incoming high-temperature air can only be discharged into the air duct 101 through the ventilation filter 302, and then be drawn into the blast chamber 104 again after being heated again, and then blown into the storage barrel 3 through the fan 106 for continuous circulation, which can improve the utilization efficiency of heat and reduce energy consumption.
[0023] Among them, in order to achieve the purpose of heating the air, the present device adopts the following technical solutions: the air duct 101 is symmetrically fixed with support legs 102, a heating wire 103 is fixed between the two support legs 102, a hydraulic telescopic rod 2 is fixed to the rear of the heating barrel 1 through the base, the upper end of the hydraulic telescopic rod 2 is rotatably connected to the upper cover 201, a stirring motor 202 is fixed on the upper cover 201, and a sleeve 203 is fixed to the output end of the stirring motor 202, and the sleeve 203 is hollow.
[0024] The heating wire 103 is fixed to the air duct 101 through the support leg 102. When the air flows back to the blast chamber 104 through the air duct 101, starting the heating wire 103 will heat the returning air again. Starting the stirring motor 202 can drive the sleeve 203 to rotate. The bottom of the sleeve 203 is hollow and can be directly put on the ventilation pipe 303 to avoid interference between the sleeve 203 and the ventilation pipe 303.
[0025] Among them, in order to achieve the purpose of stirring plastic particles, the present device adopts the following technical solutions: a stirring shaft 204 is fixedly connected to the sleeve 203, a through groove 205 is opened on the outer wall of the sleeve 203, the through groove 205 is communicated with the inside of the sleeve 203, and an insulating handle 301 is fixedly connected to the upper edge of the storage barrel 3.
[0026] The sleeve 203 can drive the stirring shaft 204 to rotate, and the rotation of the stirring shaft 204 can stir the plastic particles inside the storage barrel 3, thereby further evenly heating the plastic particles inside. The through groove 205 is connected to the inside of the sleeve 203. When the sleeve 203 is inserted into the ventilation pipe 303, the through groove 205 can discharge hot air into the storage barrel 3. The heat-insulating handle 301 makes it easy to take the storage barrel 3 out of the heating barrel 1 after softening is completed.
[0027] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the storage barrel 3 is placed into the heating barrel 1, the hydraulic telescopic rod 2 is started to drive the upper cover 201 to move down, and it should be noted that the sleeve 203 needs to be aligned with the ventilation pipe 303, so that the upper cover 201 moves down to drive the sleeve 203 to be inserted into the ventilation pipe 303, so that the upper cover 201 covers the upper edge of the storage barrel 3, and the top of the storage barrel 3 is blocked, and the fan 106 is started to blow air into the storage barrel 3, and the heating wire 103 is started to heat the air inside the heating barrel 1, so as to continuously heat the plastic particles inside the storage barrel 3 by hot air, and the stirring motor 202 is started to drive the stirring shaft 204 to rotate, so that the heating of the plastic particles can be more uniform.
