[0025] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manner, structure, features and their effects of the present utility model as follows.

[0026] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0027] A mixing chamber for masterbatch mixing, including the external bin body 1 of the mixing chamber, and further including:

[0028] A plurality of stirring augers 3 arranged inside the external bin body 1 of the mixing chamber and a driving assembly 4 for driving the stirring augers 3 to rotate. The plurality of stirring augers 3 rotate synchronously in opposite directions under the drive of the driving assembly 4 to mix the masterbatch inside the external bin body 1 of the mixing chamber;

[0029] Each stirring auger 3 is further provided with a secondary mixing part, and the secondary mixing parts are evenly distributed on the stirring auger 3. When the stirring auger 3 rotates, the secondary mixing part blocks the masterbatch, prompting the masterbatch to be turned and mixed for the second time;

[0030] The driving assembly 4 includes a power source. One end of the power source is connected with a driving gear 42. A driven gear 43 meshing with it is arranged above the driving gear 42, and driven wheels 44 are arranged on both sides of the driving gear 42;

[0031] It should be noted that: a driving wheel is fixed on the driving gear 42. At the same time, the driving wheel is connected with two driven wheels 44 through a belt. The rotation directions of the two stirring augers 3 driven by the driven wheels 44 are opposite to the rotation direction of the stirring auger 3 driven by the driving gear 42;

[0032] The driving assembly 4 is arranged inside the dust-proof cover 14. The power source is fixedly arranged above the motor base 15. There are two driven wheels 44 in total. The driving wheel on one side of the driving gear 42 is connected with the driven wheel 44 through a belt.

[0033] It should be noted that: the power source is preferably a driving motor 41. The output shaft of the driving motor 41 is fixedly connected with the driving gear 42, and the lower end of the driving motor 41 is fixedly connected above the motor base 15.

[0034] There are multiple copper tube holes 11 provided on the outer housing 1 of the kneading chamber. An inlet 12 is provided above the outer housing 1 of the kneading chamber, and an outlet 13 is provided below the outer housing 1 of the kneading chamber. A dust cover 14 is fixedly connected to the outside of the outer housing 1 of the kneading chamber. A motor base 15 is connected below the dust cover 14. The interval between the evenly distributed copper tube holes 11 on both sides of the outer housing 1 of the kneading chamber is 2 cm.

[0035] It should be noted that: the inlet 12 can be opened and closed by pushing and pulling a sliding door provided inside it, and the same applies to the outlet 13.

[0036] A primary heat source is fixedly connected inside the outer housing 1 of the kneading chamber. A secondary heat source is wound around the primary heat source. A primary heat source is provided inside each of the several copper tube holes 11. A secondary heat source is closely wound around each group of primary heat sources. Both the primary heat source and the secondary heat source can generate heat.

[0037] It should be added that: the primary heat source is preferably a heating copper tube 2, and the secondary heat source preferably uses a heating copper wire 21, and the heating copper wire 21 is wound around the heating copper tube 2.

[0038] A stirring auger 3 is provided inside the outer housing 1 of the kneading chamber. One side of the stirring auger 3 is connected to a bearing 31. A number of groups of secondary stirring blades 32 are fixedly connected to the stirring auger 3. The secondary stirring blade 32 includes a lower stirring blade 321, and a upper stirring blade 322 is fixedly connected to the lower stirring blade 321;

[0039] It should be noted that the stirring auger 3 is composed of a central stirring shaft and spiral primary stirring blades fixed to the stirring shaft, and the secondary stirring blades 32 are evenly distributed on the spiral primary stirring blades.

[0040] There are three groups of stirring augers 3 in total. One group is provided above, and two groups are provided below. One end of the stirring auger 3 provided above is fixedly connected to the inner ring of the bearing 31, and the other end passes through the outer housing 1 of the kneading chamber and is fixedly connected to the driven gear 43. One end of the two groups of stirring augers 3 provided below is fixedly connected to the inner ring of the bearing 31, and the other end passes through the outer housing 1 of the kneading chamber and is fixedly connected to the driven wheel 44. The outer rings of the three groups of bearings 31 are fixedly connected to the inner wall of the outer housing 1 of the kneading chamber.

[0041] It is worth adding that: After the stirring lower blade 321 and the stirring upper blade 322 are welded together under stirring, an L-shaped secondary stirring blade 32 is formed. The middle area of the L-shaped secondary stirring blade 32 is an L-shaped material blocking area. During the rotation of the stirring auger 3, the masterbatch will be continuously flipped and stirred under the drive of the stirring auger 3. During this process, the masterbatch will be blocked by the L-shaped secondary stirring blade 32 and enter the L-shaped material blocking area, and then fall along the secondary stirring blade 32 under its own gravity. During the falling process, it will be flipped again, so as to effectively increase the disorder during the rotational stirring process, and further effectively increase the uniformity of stirring;

[0042] At the same time, the angle between the stirring lower blade 321 and the spiral primary stirring blade on the stirring auger 3 is 75°. This angle design can make the masterbatch slide more smoothly when it enters the L-shaped material blocking area, which is more conducive to the stirring of the melted masterbatch in the space between the secondary stirring blade 32 and the stirring auger 3.

[0043] The side of the outer bin body 1 of the mixing chamber where the heat source is provided is made of heat-conducting material, and the two sides without the heat source are made of heat-insulating material.

[0044] The specific principle is as follows: Start the device, put the masterbatch raw material from the feeding port 12. The heating copper tube 2 and the heating copper wire 21 wound on it will generate heat to melt the masterbatch raw material. At the same time, the driving motor 41 located on the motor base 15 will drive the driving gear 42 to rotate. The driving gear 42 will drive the driven gear 43 above to rotate, and at the same time drive the two groups of driven wheels 44 below to rotate in the opposite direction through the belt. Since one end of the stirring auger 3 is fixedly connected to the inner ring of the bearing 31, the driven gear 43 and the driven wheels 44 will drive the three stirring augers 3 to rotate and extrude the masterbatch raw material. During the rotation of the stirring auger 3, the masterbatch will be continuously flipped and stirred under the drive of the stirring auger 3. During this process, the masterbatch will be blocked by the L-shaped secondary stirring blade 32 and enter the L-shaped material blocking area, and then fall along the secondary stirring blade 32 under its own gravity. During the falling process, it will be flipped again, so as to effectively increase the disorder during the rotational stirring process, and further effectively increase the uniformity of stirring. At the same time, in the middle L-shaped material blocking area, the melted masterbatch can not only be stirred between the stirring augers 3, but also be stirred in the space between the secondary stirring blade 32 and the stirring auger 3, increasing the irregular stirring during the stirring process, thereby increasing the uniformity of stirring; After the masterbatch raw material is stirred and mixed evenly, open the discharge port 13 to discharge the mixed masterbatch raw material into the next process.
