[0024] In order to make the purpose and advantages of the present application clearer and more apparent, the present application will be specifically described below in conjunction with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the present application, and does not strictly limit the scope of protection specifically requested by the present application.
[0025] As shown in Figures 1-5 A plastic additive production dry-wet material mixing machine, comprising a mixing tank 1 in the form of a top opening, two bases 2 distributed on both sides of the mixing tank 1, and two rotating shafts 3 penetrating through the bases 2, the base 2 can be fixed to the factory floor with bolts, during operation, an appropriate amount of filler, stabilizer, lubricant, and modifier are weighed according to the process requirements and poured into the mixing tank 1 from the opening, since one end of each rotating shaft 3 extends into the mixing tank 1 and one end of each rotating shaft 3 is welded with a flange plate 4, the other end of each rotating shaft 3 is provided with a driving element for rotation, during rotation, one flange plate 4 end face is driven to rotate along the circumferential array distribution of a plurality of first stirring rods 5, and the other flange plate 4 end face is driven to rotate along the circumferential array distribution of a plurality of second stirring rods 7, in this embodiment, 10 first stirring rods 5 and 10 second stirring rods 7 are used to stir the mixture around the horizontal central axis of the mixing tank 1, the rotation directions of the two are opposite, and the mixture can be stirred in different directions, and after the mixture is thrown and falls onto the concave surface of the mixing tank 1, the balling impurities in the mixture can be collected at the lowest point. Figure 2 As shown in
[0026] Further, the edges of the first cutting piece 6 and the edges of the second cutting piece 8 are provided with cutting edges, which can cut the pellet impurities with the cutting edges, and will not hinder the stirring of the mixture, and can promote the rapid shearing of the pellet impurities.
[0027] Referring to the drawings Figure 1 The driving element includes a belt 13 sleeved on one end of the rotating shaft 3, and the belt 13 is connected with a servo motor 14 away from the rotating shaft 3. The servo motor 14 can be a YEJ three-phase asynchronous motor, which is controlled by an external controller and transmits control signals through a relay. When starting, the two servo motors 14 drive the two rotating shafts 3 to rotate in different directions through the guide wheels and the belt 13, which can drive the 10 first stirring rods 5 and the 10 second stirring rods 7 to stir the mixture in opposite directions.
[0028] Referring to the drawings Figure 2 , Figure 3 and Figure 4 In order to make the stirring process more stable, two inner bearing sleeves 9 and a coupling 10 located in the middle of the two inner bearing sleeves 9 are arranged axially between the end faces of the two flanges 4 in the embodiment. The two inner bearing sleeves 9 are welded to the end faces of the two flanges 4, and the coupling 10 is inserted into the inner portions of the two inner bearing sleeves 9. The two inner bearing sleeves 9 are supported at the insertion positions by six bearings, so that the two inner bearing sleeves 9 can be supported by the coupling 10 while rotating with the two flanges 4, and the two flanges 4 can be uprightly limited by the two inner bearing sleeves 9, which can promote the stable stirring.
[0029] Referring to the drawings Figure 1 After the mixture is stirred uniformly, it needs to be discharged. In order to save labor, an electric hoist 16 and a traction belt 15 wound on the output end of the electric hoist 16 are arranged outside the mixing tank 1. The traction belt 15 can be made of nylon material, which can bear large load. The electric hoist 16 can be a HC large electric hoist, which is controlled by an external controller and transmits control signals through a relay. Since one end of the traction belt 15 away from the electric hoist 16 is wound outside the mixing tank 1, when the electric hoist 16 winds the traction belt 15, the mixing tank 1 is pulled relative to the circular track of the base 2 in the forward direction by the traction belt 15, until the mixture flows out of the opening of the mixing tank 1 and is collected by a collector, and then the traction belt 15 is unwound, so that the mixing tank 1 slowly resets under the action of gravity.
[0030] Referring to the drawings Figure 1 A counterweight 11 offset from the base 2 is welded to the bottom of the mixing tank 1, which lowers the center of gravity of the mixing tank 1 and is beneficial to the stability of the mixing tank 1. A glass cover 12 offset from the base 2 is installed on the top of the mixing tank 1 through a hinge shaft, which is convenient for feeding or discharging when opened, and can prevent the mixture from splashing during stirring when closed.

[0032] Referring to the drawings Figure 1 The two bases 2 are provided with a lower hopper 17 inclined to the bottom of the mixing tank 1, and the mixed material is drained by the lower hopper 17, and the mixed material can be horizontally limited due to the vertical folding of the two sides of the lower hopper 17, so that the mixed material can fall into the lower collecting vessel as much as possible.
[0033] The working principle of the utility model is as follows: during work, the required amount of filler, stabilizer, lubricant and modifier are weighed according to the process requirements and poured into the mixing tank 1 from the opening, and the first stirring rod 5 and the second stirring rod 7 are rotated by the driving element, and in the rotating process, the first stirring rod 5 and the second stirring rod 7 are rotated around the transverse central axis of the mixing tank 1, and the rotating directions of the two are opposite, so that the mixed material can be stirred in different directions, and the mixed material falls to the lower concave surface of the mixing tank 1 after being thrown, so that the balling impurities in the mixed material can be gathered at the lowest point, and due to the interlaced first cutting blade 6 and the second cutting blade 8, the shearing action can be generated when they meet the balling impurities, so that the balling impurities can be damaged to reduce the volume of the balling impurities, and through the reciprocating process, the balling impurities can be reduced or even eliminated.
[0034] The above is only an optional embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
