Finally, ensure that the feeding mechanism 3, the mixing unit B7, the mixing unit C8, and the through ports on the base 1 are communicated in sequence;

[0046] The fifth combination: Combine the base 1, the mixing unit A6, the mixing unit B7, the mixing unit C8, and the feeding mechanism 3.

[0047] Preferably, in order to adjust the position of the corresponding installation components according to the position requirements and make the installation of the device more flexible, the feeding mechanism 3 further includes a feeding cover plate 11. A first feeding port 12 and a second feeding port 13 are provided on the feeding cover plate 11. The main material feeding assembly 4 includes a main material fixing plate 14, a main material feeding pipe 15, and a main material discharging pipe 16 that slopes downward. The auxiliary material feeding assembly 5 includes an auxiliary material fixing plate 17 and an auxiliary material feeding pipe 18. The auxiliary material feeding port 10 is located on the auxiliary material fixing plate 17, and the main material feeding port 9 is located on the main material fixing plate 14. The main material fixing plate 14 and the auxiliary material fixing plate 17 are detachably connected to the feeding cover plate 11. The upper and lower parts of the auxiliary material feeding port 10 are respectively matched with the lower opening of the auxiliary material feeding pipe 18 and the first feeding port 12. The upper and lower parts of the main material feeding port 9 are respectively matched with the lower opening of the main material feeding pipe 15 and the second feeding port 13. The main material discharging pipe 16 is communicated with the inner cavity of the main material feeding pipe 15. A first gate assembly is provided below both the main material fixing plate 14 and the auxiliary material fixing plate 17. The first gate assembly includes a first cylinder 19 and a first gate 20 connected to the piston rod of the first cylinder 19. Two first gate brackets 21 are respectively fixed below the feeding cover plate 11. The first gate 20 is slidably inserted into the first gate brackets 21. A first protective cover 22 is provided outside each first gate bracket 21. The first protective cover 22 is located on the sliding track of the first gate 20. By providing a first gate assembly below both the main material fixing plate 14 and the auxiliary material fixing plate 17, the opening and closing of the feeding port are controlled. When it is necessary to open the corresponding feeding port, the first cylinder 19 is driven to work, driving the first gate 20 to move horizontally in the first gate brackets 21 to expose the corresponding feeding port for feeding. In this structure, the first protective cover 22 is provided. When the first gate 20 moves and the outer wall of the first gate 20 abuts against the first protective cover 22, the first gate 20 cannot move outward anymore. At this time, it plays a limiting role for the first gate 20 and can also play a protective role to prevent the first gate 20 from moving and colliding with people or things around. Therefore, such a structural design makes the whole operation safer. In this embodiment, the main material discharging pipe 16 is an inclined square structure. Such a setting can facilitate the falling of materials, and at the same time, the materials can be quickly discharged from the main material discharging pipe 16 during unloading.

[0048] To achieve automatic and rapid mixing, the mixing unit A6 includes a mixing cylinder 23, on which a third feed inlet 24 and a first discharge outlet 25 are provided. A stirring paddle 26 is arranged inside the mixing cylinder 23, and a motor 27 is arranged at the bottom of the mixing cylinder 23. The output of the motor 27 extends into the mixing cylinder 23 and is connected to the stirring paddle 26. By arranging the stirring paddle 26 inside the mixing cylinder 23 and driving it by the motor 27 below, when materials enter the inside of the mixing cylinder 23, the motor 27 drives the stirring paddle 26 to rotate to mix the internal materials, improving the automatic and rapid material mixing effect.

[0049] In order to achieve secondary mixing and improve the mixing effect, the mixing unit B7 includes a first vertical portion 28, a second laterally extending portion 29 provided on the upper side of the first vertical portion 28, and a third laterally extending portion 30 provided on the lower side of the first vertical portion 28. Above the second laterally extending portion 29, a fifth feed port 31 is provided. Below the first vertical portion 28, a third discharge port 32 is provided. Above the fifth feed port 31, a second gate assembly 46 is provided. Both the second laterally extending portion 29 and the third laterally extending portion 30 communicate with the inner cavity of the first vertical portion 28. On three sides of the upper part of the first vertical portion 28, a second opening 33 is provided respectively. At the three second openings 33, a hot air pipe 34, an external connection pipe 35, and a second cover plate 36 are sequentially connected. On three sides of the lower part of the first vertical portion 28, a seventh opening 70 is provided respectively. At the three seventh openings 70, the third laterally extending portion 30, a fifth cover plate 37, and a seventh cover plate 71 are detachably installed in sequence. On the fifth cover plate 37, a motor mounting hole 38 is provided. In this embodiment, the first vertical portion 28 is of a square structure. The three second openings 33 are respectively provided on three side surfaces of the upper part of the first vertical portion 28. The second laterally extending portion 29 is provided on the fourth side surface of the upper part of the first vertical portion 28. One of the second openings 33 is used for installing the hot air pipe 34, another second opening 33 is used for installing the external connection pipe 35, and the third second opening 33 is used for installing the second cover plate 36. Later, the installation positions of the second cover plate 36, the hot air pipe 34, and the external connection pipe 35 on the second opening 33 can be changed according to the actual position. In this embodiment, the external connection pipe 35 is set as an expansion port, and a recycling system can be externally connected later, which can achieve two functions: 1. External recycling of materials, used to recycle the remaining materials inside; 2. Used to put in sample materials; The hot air pipe 34 is used as an expansion port to be connected to a fan later, which is used to dry or heat the internal materials; At the same time, a seventh opening 70 is provided on three sides of the lower part of the first vertical portion 28. One of the seventh openings 70 is used for installing the third laterally extending portion 30, another seventh opening 70 is used for installing the seventh cover plate 71, and the remaining seventh opening 70 is used for installing the fifth cover plate 37. The third laterally extending portion 30 is provided for installing a magnetic rack or a filter screen inside later. The motor mounting hole 38 is provided for installing a stirring mechanism inside the first vertical portion 28 later. At the same time, a motor is installed by using the motor mounting hole 38 to ensure the connection between the motor and the internal stirring mechanism, stir the inside of the first vertical portion 28, and improve the mixing efficiency. And the applicant needs to explain that the third laterally extending portion 30 and the motor mounting hole 38 cannot be used simultaneously because the installation is easily restricted, and later the installation positions of the third laterally extending portion 30, the fifth cover plate 37, and the seventh cover plate 71 on the seventh opening 70 can be changed according to the actual position.

[0050] Preferably, in order to ensure more uniform mixing, third covers 40 with third openings 39 are symmetrically arranged on both sides of the second lateral extension 29. A distributing rack 41 is arranged in the second lateral extension 29 and is located below the fifth feed inlet 31. The distributing rack 41 includes a distributing plate 42 located above. The distributing plate 42 is in a "∧" shape structure. An extension plate 43 extending downward is arranged below the distributing plate 42. Two symmetrically inclined feeding plates 44 are arranged between the two extension plates 43. The upper ends of the inclined feeding plates 44 are respectively communicated with the two corresponding third openings 39. In the above structure, a distributing rack 41 is arranged below the fifth feed inlet 31, and openings are symmetrically arranged on both sides of the distributing rack 41 as masterbatch ports for adding masterbatch. At the same time, third covers 40 with third openings 39 are symmetrically arranged on both sides of the second lateral extension 29 to ensure that the third openings 39 are communicated with the corresponding masterbatch ports. Later, a suitable masterbatch port is selected according to the installation position, and the other third cover 40 is closed with a closing plate. The closing plate and the second lateral extension 29 are connected by a screw-disassembling connection. When masterbatch needs to be added later, a masterbatch machine is externally connected through the third cover 40, and then the masterbatch is fed into the inclined feeding plate 44. At this time, the material entering from the fifth feed inlet 31 is shunted by the distributing plate 42 and then falls along the extension plate 43, and then is mixed with the masterbatch below the inclined feeding plate 44, finally ensuring more uniform mixing of the material. Therefore, this structural setting can ensure more uniform mixing. At the same time, due to the arrangement of two symmetric third openings 39, a suitable third opening 39 can be selected according to the actual installation requirements later, finally ensuring more convenient combined installation and being suitable for different types of injection molding machines.

[0051] In order to carry out feeding according to needs, the second gate assembly 46 includes a gate cover 45 installed on the second lateral extension 29, a second cylinder 47 fixed to the side of the gate cover 45, and a second gate 48 connected to the piston rod of the second cylinder 47. The fifth feed inlet 31 is arranged on the gate cover 45. A second gate support 49 is arranged above the gate cover 45. The second gate 48 is slidably inserted into the second gate support 49. A second protective cover 50 is arranged outside the second gate support 49. The second protective cover 50 is located on the sliding track of the second gate 48. In the above structure, the second cylinder 47 works to drive the second gate 48 to move horizontally along the second gate support 49, so as to control the opening and closing of the fifth feed inlet 31, ensuring that the opening of the fifth feed inlet 31 is automatically opened or closed according to needs. When the second gate 48 moves, when the outer wall of the second gate 48 abuts against the second protective cover 50, the second gate 48 can no longer move outward. At this time, it plays a limiting role for the second gate 48, and at the same time can play a protective role to avoid the second gate 48 moving and colliding with people or things around. Therefore, such a structural design makes the whole operation safer.

[0052] Preferably, in order to facilitate the installation of a filter screen or a magnetic rack in the third horizontal extension part 30 in the later stage, a fifth opening 65 communicating with the inner wall of the first vertical part 28 is provided on the third horizontal extension part 30. A fourth cover plate 52 matching with the fifth opening 65 is detachably connected to the fifth opening 65. By providing the fifth opening 65 on the third horizontal extension part 30 and the detachable fourth cover plate 52 on the fifth opening 65, when it is necessary to install a filter screen or a magnetic rack in the third horizontal extension part 30, only the fourth cover plate 52 needs to be removed, and then the filter screen or the magnetic rack is installed in the third horizontal extension part 30 by screws. By providing the magnetic rack, iron filings existing in the plastic raw materials can be effectively adsorbed. By providing the filter screen, a filtering effect can be effectively achieved. At the same time, when the motor mounting hole 38 is used and it is also necessary to install a magnetic rack or a filter screen at the same time, in order to avoid the installation of the magnetic rack or the filter screen being restricted and unable to be installed, the magnetic rack or the filter screen can be installed in the third horizontal extension part 30, so that the installation components of stirring and filtering do not affect each other.

[0053] In order to avoid mutual influence during installation, the mixing unit C8 includes a second vertical part 55 and a first horizontal extension part 51 provided on the outer wall of the second vertical part 55. A fourth feed port 56 and a second discharge port 57 are provided on the second vertical part 55. A first opening 58 communicating with the inner cavity of the second vertical part 55 is provided on the first horizontal extension part 51.
