[0002] PC / ABS material is an alloy plastic obtained by blending PC plastic and ABS plastic to obtain the excellent properties of both. On the one hand, the heat resistance, impact strength and tensile strength of PC / ABS material are better than ABS plastic. On the other hand, the melt viscosity of PC / ABS material is lower than that of PC plastic, and the processing performance is better than that of PC plastic. Therefore, PC / ABS material can be widely used in the fields of communication, electronic appliances and transportation. PC / ABS flame retardant material is a kind of PC / ABS material. Due to its good flame retardancy, it is more widely used. At present, when PC / ABS flame retardant material is produced, it is necessary to first mix raw materials such as PC particles, ABS particles and flame retardants, and then put the mixed raw materials into the extruder to melt together for production.

[0041] The processing procedures and working principles of this PC / ABS flame retardant material production equipment are as follows:

[0042] Process 1: Loading:

[0043] like Figure 1 This is the initial state of the present invention. At this time, the control mechanism 4 is in the outer circle state, the switching mechanism 5 is in the expanded state, and the stirring mechanism 6 is in the stirring state. When the present invention is used to stir the raw materials required for producing PC / ABS flame retardant materials, the barrel cover 38 needs to be opened first, and then raw materials such as PC particles, ABS particles and flame retardants are added into the barrel cavity through the frame window 21. After the raw materials are added, the barrel cover 38 is closed to complete the loading work;

[0044] Process 2: Mixing of raw materials:

[0045] When the loading is completed, the first motor 71 and the second motor 74 are started at the same time. Since the output shaft of the first motor 71 is fixedly connected to the first bevel gear 72, the first bevel gear 72 and the second bevel gear 73 are meshed, and the second bevel gear 73 is fixedly connected to the mixing drum 3, and then the mixing drum 3 is driven to rotate forward by the first motor 71, and the stirring frame 61 is driven to reverse by the second motor 74. At this time, since the switching mechanism 5 is in the expanded state, the arc plate 53 and the arc boss 36 are connected end to end to form a circular ring structure. Under the action of the torsion spring 66, one end of the telescopic rod 64 is pressed against the flap 62, and the other end of the telescopic rod 64 is tightly attached to the flap 62. The torsion spring 66 is on the arc plate 53 or the arc boss 36, so that the flap 62 cannot be driven to rotate by the torsion spring 66. One end of the flap 62 is attached to the inner wall of the mixing drum 3, and at this time, the friction wheel 65 and the friction ring 37 are in close contact. Since the stirring wheel 63 and the friction wheel 65 are fixedly connected, the stirring wheel 63 is driven to rotate, so that the raw materials shoveled on the flap 62 are stirred by the turning of the stirring blades on the stirring wheel 63. During operation, if the raw materials are stuck between the friction wheel 65 and the friction ring 37, the raw materials push the friction wheel 65 to drive the flap 62 to rotate, thereby overcoming the elastic member to compress the telescopic rod 64, so that the equipment will not be stuck. At the same time, due to When the control pin 411 slides in the annular track 31, the control rod 41 remains stationary. When the mixing drum 3 rotates forward and the control pin 411 passes the intersection of the second transition track 322 and the annular track 31, the control pin 411 slides along the annular track 31, so that the control rod 41 remains stationary. When the control pin 411 enters the intersection of the annular track 31 and the first transition track 321, the positioning ball 44 is positioned in the first positioning groove 425 at this time, and the fourth side surface 424 and the first limiting pin 34 are tightly attached, so that the third side surface 423 blocks the annular track 31. Under the action of the third side surface 423, the control pin 411 enters the first transition rail 321, thereby driving the control rod 41 to move, so that the rack 412 moves with the control rod 41. Since the rack 412 is meshed with the bottom frame gear 11, the control rod 41 slides on the swing frame 2, and the swing frame 2 is rotatably set on the column. The bottom frame gear 11 is fixedly set on the column, so that when the rack 412 moves, it drives the swing frame 2 to flip. When the control pin 411 enters the arc track 33, the rack 412 moves to drive the swing frame 2 to flip 180 degrees to the right side of the bottom frame 1, so that the mixing drum 3 is flipped, and the materials therein are flipped, thereby completing the raw material mixing work;

[0046] Process 3: Turn over the raw materials:

[0047] As the control pin 411 slides along the arc track 33, the first side surface 421 blocks the arc track 33 at this time, so that when the control pin 411 contacts the first side surface 421, as the mixing drum 3 rotates, the control pin 411 pushes the first side surface 421 to drive the control plate 42 to rotate, so that the positioning ball 44 switches from the first positioning groove 425 to the second positioning groove 426, and at the same time, the third side surface 423 and the second limiting pin 35 are closely attached, the fourth side surface 424 blocks the first transition track 321, and the second side surface 422 blocks the annular track 31, so that the control pin 411 and the first side surface 421 are in contact with each other. The mechanism 4 switches to the outer ring state. Since the control plate 42 and the switching rod 54 are fixedly connected to the control shaft 43, the control plate 42 drives the switching rod 54 to rotate. Since the switching pin 541 slides in the switching groove 511, the switching disk 51 is driven to rotate, and the arc plate 53 is driven to rotate through the connecting rod 52, so that the switching mechanism 5 switches to the retracted state. Since the arc plate 53 rotates, the free end of the arc plate 53 and the arc boss 36 are separated. When the telescopic rod 64 slides to the end along the arc boss 36, the telescopic rod 64 is separated from the arc boss 36. Under the action, the flap 62 is driven to rotate, and the raw materials shoveled on the flap 62 are lifted. At the same time, due to the rotation of the flap 62, the friction wheel 65 and the friction ring 37 are separated. The rotation of the flap 62 can push the telescopic rod 64 to slide, so that the other end of the telescopic rod 64 is against the arc plate 53, and the arc plate 53 drives the flap 62 to overcome the torsion spring 66 and reverse, until the telescopic rod 64 is in close contact with the arc boss 36 again, the friction wheel 65 is in close contact with the friction ring 37 again, and the driving stirring wheel 63 works again. In this process, the stirring mechanism 6 is in a lifting state, thereby spreading and stirring the raw materials. Mixing action: when the control pin 411 enters the second transition rail 322 from the third rail 33, it drives the control rod 41 to move in the reverse direction, and then drives the swing frame 2 to swing in the reverse direction through the cooperation of the bottom frame gear 11 and the rack 412. Since the mixing drum 3 rotates forward, the control pin 411 passes through the intersection of the second transition rail 322 and the annular rail 31 and slides along the annular rail 31. When the control pin 411 arrives, the rack 412 resets and drives the swing frame 2 to rotate 180 degrees, and drives the mixing drum 3 to reset, so as to achieve multi-directional mixing, and the raw materials are mixed more evenly, and the work of flipping the raw materials is completed;

[0048] Process 4: Reset work:

[0049] As the control pin 411 slides along the first track 31, the control pin 411 comes to the intersection of the annular track 31 and the first transition track 321 again. At this time, the positioning ball 44 is positioned in the second positioning groove 426, and the third side surface 423 and the second limiting pin 35 are in close contact, so that the fourth side surface 424 blocks the first transition track 321. Under the action of the fourth side surface 424, the control pin 411 still slides along the annular track 31, so that the control rod 41 does not move relative to the swing frame 2. As the control pin 411 slides along the annular track 31, at this time, the second side surface 422 blocks the annular track 31, so that at the intersection of the control pin 411 and the second side surface When the second side 422 contacts, the control pin 411 pushes the second side 422 to drive the control plate 42 to reverse, so that the positioning ball 44 switches from the second positioning groove 426 to the first positioning groove 425, and at the same time, the fourth side 424 and the first limit pin 34 are closely attached, the third side 423 blocks the annular track 31, and the first side 421 blocks the arc track 33, so that the control mechanism 4 switches to the inner circle state, and at the same time drives the switching rod 54 to reverse, and drives the arc plate 53 to reset through the switching disk 51, and the switching mechanism 5 switches to the expanded state, so that the stirring mechanism 6 returns to the stirring state, so that the equipment returns to the initial state and works to form a cycle;

[0050] Process 5: Alternating work:

[0051] In summary, by controlling the first motor 71 and the second motor 74 to rotate continuously, the equipment can be controlled to alternately repeat the process 2, the process 3 and the process 4, so that the raw materials can be stirred at multiple angles and in multiple ways, making the mixing more complete until the stirring work is completed;

[0052] Process 6: Cutting:

[0053] When the mixing is completed, the mixing drum 3 is controlled to rotate so that the drum cover 38 comes to the lower position, and the drum cover 38 is opened to pour out the raw materials in the mixing drum 3, and the raw materials are collected manually to complete the unloading.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
