DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 7A plastic particle softening device comprises a softening cylinder 1 and a cover body 2 installed on the softening cylinder 1, the upper surface of the cover body 2 is fixedly connected to a feed hopper 3, the feed hopper 3 is communicated with the interior of the softening cylinder 1, the upper surface of the cover body 2 is connected to a power mechanism, the power mechanism is connected to a stirring assembly, the other end of the stirring assembly passes through the cover body 2, the inner wall of the lower end of the softening cylinder 1 is connected to a support assembly, the other end of the support assembly is connected to an end of the stirring assembly away from the power mechanism, and a heating mechanism is connected to the interior of the support assembly and the stirring assembly.

[0026] The plastic granule softening device in the utility model is similar in structure to the existing plastic granule softening device, such as a uniformly heated plastic granule softening processing device disclosed in the patent with announcement number CN218776918U. Figures 1 to 7 As shown, when the plastic granule softening device in the utility model softens the plastic granules, it is only necessary to put the plastic granules from the feed hopper 3 on the cover body 2 into the softening cylinder 1, and then turn on the power mechanism and the heating mechanism. After the power mechanism is started, the stirring component can be driven to stir the plastic granules inside the softening cylinder 1, so that the force on the plastic granules is more uniform, and after the heating mechanism is started, the stirring component can be heated, and then the plastic granules can be heated and softened while the stirring component is stirring, thereby reducing the overall softening time of the plastic granules, and thus providing softening efficiency.

[0027] like Figure 1-Figure 3 , Figure 5 and Figure 6 As shown, the power mechanism includes a motor 4, the outer wall of the motor 4 is fixedly connected to the upper surface of the outer wall of the cover body 2, and the output shaft of the motor 4 is connected to the stirring assembly.

[0028] More specifically, when the plastic particles need to be stirred, the motor 4 only needs to be turned on. After the motor 4 is started, the output shaft can drive the stirring component to rotate inside the softening cylinder 1, thereby stirring the plastic particles.

[0029] like Figure 5 and Figure 6 As shown, the stirring assembly includes a stirring rod 5 and an inner auger disc 12, one end of the stirring rod 5 is fixedly connected to the output shaft of the motor 4, the other end of the stirring rod 5 passes through the cover body 2 and is fixedly connected to the inner auger disc 12, the end of the stirring rod 5 away from the motor 4 is connected to the support assembly, and the heating mechanism is connected to the stirring rod 5.

[0030] More specifically, when the motor 4 is started, the output shaft drives the stirring rod 5 to rotate. When the stirring rod 5 rotates, it can drive the inner auger disk 12 to rotate. When the inner auger disk 12 rotates, the plastic particles inside the softening cylinder 1 can be stirred. Because the heating mechanism is connected to the stirring rod 5, the stirring rod 5 will transfer the heat of the heating mechanism to the surface of the stirred plastic particles through the inner auger disk 12. Because the plastic particles will be in contact with the inner auger disk 12 for a longer time when rising in the inner auger disk 12, the softening of these plastic particles can be accelerated.

[0031] like Figure 6 and Figure 7 As shown, the support assembly includes a support tube 9 and a support seat 11, the outer wall of the support tube 9 is fixedly connected to the inner wall of the lower end of the softening cylinder 1, the other end of the support tube 9 is fixedly connected to the side wall of the support seat 11, the upper surface of the support seat 11 is rotatably connected to the end of the stirring rod 5 away from the motor 4, and the heating mechanism is connected to both the support tube 9 and the support seat 11.

[0032] More specifically, the support assembly can not only provide support for the lower end of the stirring assembly, but also provide protection for the heating mechanism to prevent the plastic particles from colliding with the heating mechanism during the stirring process, thereby accelerating damage to the heating mechanism.

[0033] like Figure 6 As shown, a heating chamber 501 is provided inside the stirring rod 5 , and a heating mechanism is located inside the heating chamber 501 . A connecting chamber 901 communicating with the heating chamber 501 is provided on the inner walls of the supporting tube 9 and the supporting seat 11 , and the heating mechanism is located inside the connecting chamber 901 .

[0034] More specifically, by providing the heating chamber 501 and the connecting chamber 901, the heating mechanism can be housed and protected, thereby preventing the heating mechanism from occupying external space and colliding with plastic particles to cause wear or even breakage.

[0035] like Figure 6 and Figure 7 As shown, the heating mechanism includes a connecting wire 10 and a heating tube 13. The heating tube 13 is located in the heating chamber 501, and the connecting wire 10 is located in the connecting chamber 901. The lower end of the heating tube 13 is fixedly connected to the upper surface of the support seat 11 and is electrically connected to one end of the connecting wire 10. The other end of the connecting wire 10 passes through the connecting chamber 901.

[0036] More specifically, when it is necessary to soften the plastic particles, it is only necessary to turn on the motor 4 and energize the connecting wire 10. After the connecting wire 10 is energized, the heating tube 13 will generate heat. After the heating tube 13 generates heat, it can transfer its own heat to the stirring rod 5 and the inner auger disc 12 through the heating chamber 501. Because the stirring rod 5 and the inner auger disc 12 are made of materials with good thermal conductivity (such as aluminum, of course, it can also be other metal or non-metal materials, which are not specifically limited), the heat can be transferred to the plastic particles very well, thereby accelerating the softening of the plastic particles.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, the upper end of the stirring rod 5 is fixedly connected to a plurality of connecting frames 6, and the other ends of the plurality of connecting frames 6 are fixedly connected to an outer cover 7 at the same time. The inner wall of the outer cover 7 is fixedly connected to an outer auger disc 8, and the outer auger disc 8 does not contact the inner auger disc 12.

[0038] More specifically, by providing the connecting frame 6, the outer cover 7 and the outer auger disc 8, firstly, it can be prevented that some plastic particles are always located on the inner wall of the softening cylinder 1 without contacting the inner auger disc 12, resulting in that these plastic particles cannot be softened better and faster; secondly, after the inner auger disc 12 transports the plastic particles to the top of the softening cylinder 1, the outer auger disc 8 slowly brings them down, so that most of the plastic particles can be prevented from accumulating at the lower end of the softening cylinder 1, thereby affecting the softening effect. It should be particularly noted here that the spiral directions of the outer auger disc 8 and the inner auger disc 12 are opposite.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
