When feed pipe 11 rotates, it can pass through. A battery for powering annular weight sensor 31 is provided on circular plate 23 as needed.

[0045] It also includes: a stirring assembly for stirring the plastic raw materials in the storage tank 25, and the stirring assembly is located in the storage tank 25;

[0046] The stirring assembly includes: a rotating rod 40, a stirring shaft 41, and a second servo motor 42;

[0047] The rotating rod 40 is rotatably connected to the top of the storage tank 25 via bearings. Several stirring shafts 41 are fixedly installed on the rotating rod 40.

[0048] It also includes: a drying assembly for keeping the storage tank 25 in a dry state, and the drying assembly is disposed on the mixing tank 10;

[0049] The drying assembly includes: a hollow tube 50, a first filter screen 51, a heating wire 52, a fan 53, a T-shaped block 54, a second filter screen 55, and a silica gel desiccant 56;

[0050] Hollow tubes 50 are fixedly installed on both side walls of the storage tank 25. A first filter screen 51 is fixedly installed inside the hollow tube 50. A heating wire 52 is fixedly installed in a spring shape in the hollow tube 50 outside the first filter screen 51. A fan 53 is fixedly installed in the hollow tube 50 outside the heating wire 52. A T-shaped block 54 is threaded to one end of the hollow tube 50. A second filter screen 55 is fixedly installed on both sides of the middle part of the T-shaped block 54. Silica gel desiccant 56 is placed in the T-shaped block 54 and is located between the two sets of second filter screens 55. The installation height of the hollow tubes 50 can be set according to requirements. If the raw material in the storage tank 25 is liquid, both sets of hollow tubes 50 need to be installed at a higher position. If the raw material in the storage tank 25 is solid, one set of hollow tubes 50 needs to be installed at a higher position and the other set of hollow tubes 50 needs to be installed at a lower position. In addition, the two fans 53 run in opposite directions, and the running directions of the two sets of fans 53 can be interchanged.

[0051] When mixing plastic materials, the specific operating steps for those skilled in the art are as follows:

[0052] First, the corresponding plastic raw material is placed in the storage tank 25 through the feeding pipe for storage. During this process, the plastic raw material in the storage tank 25 is stirred by the cooperation of the second servo motor 42, the rotating rod 40, and the stirring shaft 41. At the same time, the fan 53 circulates air in the storage tank 25. During the air circulation, the silica gel desiccant 56 absorbs moisture in the air, thus keeping the plastic raw material in a dry environment to prevent it from absorbing moisture and condensing. When feeding is required, the first servo motor 22 positions the corresponding discharge pipe 26 directly above the feed pipe 11, allowing the plastic raw material to pass through the discharge pipe 26. 6 and feed pipe 11 fall into mixing tank 10 until the ring weight sensor 31 reaches the set value range. During the feeding process, the mixing component and drying component can be turned off as needed. When the plastic raw material is in mixing tank 10, it can be mixed by the mixing structure in mixing tank 10. When the silica gel desiccant 56 is saturated, the fan 53 blows air towards the silica gel desiccant 56. At this time, the heating wire 52 heats the air to heat and release the silica gel desiccant 56. When heating and releasing the silica gel desiccant 56, only one set of silica gel desiccant 56 can be released at a time. Two sets of silica gel desiccant 56 cannot be released at the same time.

[0053] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
