[0043] Specifically, when in use, the plastic particles are placed into the shell 11 from the top opening of the shell 11, and then the first motor 413 is started, and the output end of the first motor 413 rotates, and the output end of the first motor 413 drives the fan blades 414 to rotate, and the fan blades 414 draw the hot air in the melting device 3 into the internal space of the mounting disk 411 through the discharge barrel 2, and then the hot air enters the air cavity 415 through the internal space of the mounting disk 411, so that the rotating shaft 42 is heated, and the plastic particles in the shell 11 are heated, thereby improving the dryness of the plastic particles in the shell 11; after the plastic particles have been dried for a period of time, the mounting disk 411 is moved, so that the plastic particles in the shell 11 enter the melting device 3 through the discharge barrel 2 for melting.

[0044] By setting the shell 11, plastic particles can be accommodated, and by setting the discharge barrel 2, the melting device 3 can be connected to the shell 11, thereby reducing the contact between the plastic particles and the external air in the process of entering the melting device 3 from the shell 11, and by setting the vacuum part 41, the fan blade 414 can be driven to rotate by the first motor 413 to introduce the residual heat in the melting device 3 into the air cavity 415, so that the residual heat heats and dries the plastic particles in the shell 11, thereby improving the heat utilization efficiency of the melting device 3, and being able to dry the raw materials to improve the quality of the produced plastic parts.

[0045] like Figure 2 , 3 As shown in 4, the bottom end of the shell 11 is inverted cone shape, the bottom end of the discharge barrel 2 is cone shape, the top end of the shell 11 is detachably connected with a closing cover 13, the closing cover 13 is provided with a moving part 43, the moving part 43 includes two electric push rods 431 fixedly connected to the top end of the closing cover 13, the rotating shaft 42 extends upward and passes through the closing cover 13, the rotating shaft 42 is rotatably connected to the closing cover 13, and the output end of the electric push rod 431 is connected to the top end of the rotating shaft 42.

[0046] Specifically, in the initial state, the mounting disk 411 is located at the top of the discharge barrel 2, and the mounting disk 411 closes the top of the discharge barrel 2; when discharging is required, the electric push rod 431 is started, the output end of the electric push rod 431 contracts, the output end of the electric push rod 431 drives the rotating shaft 42 to move downward, the rotating shaft 42 drives the mounting disk 411 to move downward, the mounting disk 411 moves to the conical section of the discharge barrel 2, and then the plastic particles in the shell 11 move downward through the bottom end of the discharge barrel 2, and then the plastic particles enter the melting device 3; after all the plastic particles enter the melting device 3, the electric push rod 431 is started, the output end of the electric push rod 431 moves upward, the output end of the electric push rod 431 drives the rotating shaft 42 to move upward, the rotating shaft 42 drives the mounting disk 411 to move upward, so that the mounting disk 411 is reset to the top of the discharge barrel 2, and the mounting disk 411 closes the discharge barrel 2 again.

[0047] The inverted cone-shaped setting at the bottom of the shell 11 facilitates the discharge of plastic particles from the discharge port 12 at the bottom of the shell 11, and the setting of the moving part 43 allows the discharge barrel 2 to be opened by moving the rotating shaft 42 and the mounting plate 411 downward when discharge is required, so that the plastic particles enter the melting device 3. After the discharge is completed, the mounting plate 411 can be moved upward to close the discharge barrel 2, thereby facilitating the continuous use of the device.

[0048] Furthermore, the electric push rod 431 is a prior art and will not be described in detail.

[0049] like Figure 2 , 4 As shown in Figures 6 and 7, the processing mechanism 4 further includes four stirring members 44 evenly arranged on the rotating shaft 42 at equal intervals, and the stirring member 44 includes four sliding rods 441 evenly arranged on the rotating shaft 42 along the circumferential direction, and a connecting groove 442 is provided in the sliding rod 441, and the ends of the four sliding rods 441 in the same vertical direction of the four stirring members 44 are commonly fixedly connected with an auxiliary rod 443, and a cavity 444 is provided in the auxiliary rod 443, and the connecting groove 442 and the cavity 444 are connected. The cavity 444 is connected, and a side wall near the rotating shaft 42 is provided with five air holes 445 at equal intervals in the vertical direction. The air holes 445 are connected to the internal space of the shell 11. A connecting pipe 446 is provided in the connecting groove 442. The connecting pipe 446 is connected to the air cavity 415. The connecting pipe 446 is fixedly connected to the rotating shaft 42. The top end of the rotating shaft 42 is fixedly connected to the output end of the second motor 447. The second motor 447 is fixedly connected to the output end of the electric push rod 431.

[0050] Specifically, when in use, the second motor 447 is started, and the output end of the second motor 447 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives the connecting pipe 446 and the sliding rod 441 to rotate, the sliding rod 441 drives the auxiliary rod 443 to rotate, and the auxiliary rod 443 and the sliding rod 441 stir the plastic particles in the shell 11; at the same time, the vacuum part 41 draws hot air into the air cavity 415, and the hot air enters the connecting groove 442 through the connecting pipe 446, and then the gas enters the cavity 444 through the connecting groove 442, and then the gas is discharged into the shell 11 through the air hole 445 to dry the plastic particles in the shell 11.

[0051] Through the setting of the stirring member 44, the auxiliary rod 443 and the sliding rod 441 can be driven to rotate through the rotating shaft 42 to stir the plastic particles in the shell 11, so that the plastic particles in the shell 11 are fully mixed and the plastic particles are distributed more evenly. Moreover, through the setting of the connecting pipe 446 and the connecting groove 442, the hot air in the air cavity 415 can be guided into the cavity 444 and blown into the plastic particles in the shell 11 through the air holes 445, thereby improving the drying effect of the plastic particles.

[0052] like Figure 4 , 6 As shown, the stirring member 44 also includes a rod sleeve 448 slidably mounted on the sliding rod 441, the rod sleeve 448 is fixedly connected to the rotating shaft 42, a first spring 449 is connected between the sliding rod 441 and the rotating shaft 42, the connecting tube 446 is located in the rod sleeve 448, and the first spring 449 is located in the rod sleeve 448.

[0053] Specifically, during use, when the rotating shaft 42 rotates, the rotating shaft 42 drives the rod sleeve 448, the sliding rod 441 and the auxiliary rod 443 to rotate. Since the auxiliary rod 443 is acted upon by centrifugal force, the auxiliary rod 443 drives the sliding rod 441 to stretch the first spring 449, so that the sliding rod 441 extends out of the rod sleeve 448; the rotation speed of the second motor 447 is changed, so that the centrifugal force on the auxiliary rod 443 changes, so that the sliding rod 441 slides in the rod sleeve 448, thereby changing the position of the auxiliary rod 443 and increasing the stirring area of ​​the auxiliary rod 443.

[0054] By setting the rod sleeve 448 and the first spring 449, during the stirring process, the rotation speed of the second motor 447 can be changed to change the position of the auxiliary rod 443, thereby increasing the stirring area of ​​the auxiliary rod 443, thereby improving the stirring effect and the drying effect, making the plastic particles mixed more evenly and drier, and improving the quality of the produced plastic parts.

[0055] like Figure 4 , 10As shown, the processing mechanism 4 also includes four dosing members 45 arranged in the air cavity 415 at equal intervals from top to bottom, and the dosing member 45 includes a storage cylinder 451 slidably arranged in the air cavity 415, and a storage cavity 452 is opened in the storage cylinder 451. A push ring 453 is slidably connected in the storage cavity 452, and a second spring 454 is connected between the push ring 453 and the bottom wall of the storage cavity 452. A connecting rod 455 is fixedly connected to the lower side of the push ring 453. The connecting rod 455 extends downward from the storage cylinder 451, and the bottom end of the connecting rod 455 is fixedly connected to a movable ring 456.

The storage cavity 452 contains additives, and the inner wall of the air cavity 415 is fixedly connected to a limiting ring, which is located on the upper side of the storage cylinder 451 and can abut against the top of the storage cylinder 451.

[0056] Specifically, in the initial state, the dosing member 45 is located at the lower side of the connecting tube 446; during use, when it is necessary to add additives to the plastic particles, the storage cylinder 451 is moved upward, the storage cylinder 451 moves upward, so that the connecting hole 457 is connected with the connecting tube 446, and at the same time, the top of the storage cylinder 451 abuts against the limit ring, and then the moving ring 456 is moved upward, the moving ring 456 drives the connecting rod 455 to move upward, and the connecting rod 455 drives the push ring 453 to move upward, and the push ring 453 pushes the additive in the storage cavity 452 into the connecting tube 446 through the connecting hole 457, and then the additive enters the cavity 444 through the connecting tube 446, and then the additive enters the plastic particles through the air hole 445, and the additive and the plastic particles are mixed evenly with the stirring of the auxiliary rod 443.

[0057] Through the setting of the additive piece 45, when it is necessary to add additives to the plastic particles, the storage tube 451 can be used to allow the additives to enter the cavity 444 through the connecting hole 457, and the additives can enter the plastic particles through the air holes 445. In addition, the auxiliary rod 443 can be used to stir the additives so that the additives and the plastic particles are evenly mixed, thereby further improving the production quality of the plastic parts.

[0058] like Figure 4 , 7 As shown, the processing mechanism 4 also includes an anti-return component 46, and the anti-return component 46 includes a one-way valve 461 arranged at the connection between the connecting pipe 446 and the cavity 444. A push plate 462 is slidably connected in the cavity 444, and a third spring 463 is connected between the side of the push plate 462 away from the rotating shaft 42 and the side wall of the cavity 444.

[0059] Specifically, when in use, after the additive enters the connecting pipe 446 , it enters the cavity 444 through the one-way valve 461 , and then the additive is completely squeezed out of the cavity 444 under the thrust of the push plate 462 and the third spring 463 .

[0060] The anti-return member 46 can prevent the additive from flowing back, and under the action of the push plate 462 and the third spring 463, all the additives in the cavity 444 enter into the plastic particles, thereby improving the utilization rate of the additives and ensuring the amount of additives added.

[0061] Furthermore, the one-way valve 461 is a prior art and will not be described in detail.

[0062] like Figure 4 , 9 As shown in 10, the dosing member 45 is connected to the moving member 47, and the moving member 47 includes an electric rod 471 fixedly connected to the top of the air cavity 415, and the output end of the electric rod 471 is fixedly connected to a linkage rod 472, and the linkage rod 472 extends downward through the inner ring of the moving ring 456. The linkage rod 472 is fixedly connected to an abutment ring 473, and the abutment ring 473 can abut against the bottom surface of the moving ring 456.

[0063] Specifically, during use, when the dosing member 45 needs to move upward, the electric rod 471 is started, the output end of the electric rod 471 contracts, the output end of the electric rod 471 drives the linkage rod 472 to move upward, the linkage rod 472 drives the abutment ring 473 to move upward, the abutment ring 473 drives the storage cylinder 451 to move upward through the moving ring 456, when the storage cylinder 451 abuts against the limiting ring, the abutment ring 473 continues to move upward, the abutment ring 473 drives the moving ring 456 to continue to move upward, and the additive in the storage cylinder 451 is squeezed out.

[0064] The moving member 47 can drive the dosing member 45 to move upward, and the movement of the abutting ring 473 can drive the additive in the storage cylinder 451 to be squeezed out.

A connecting cavity 482 is opened in the closing cover 13, and the connecting cavity 482 is evenly connected with four connecting grooves 483 along the circumferential direction, and the connecting grooves 483 are connected with the auxiliary cavity 481. Four through holes 484 are evenly opened on the inner wall of the air cavity 415 along the circumferential direction, and the through holes 484 are connected with the connecting cavity 482. A first closed ring 485 is fixedly connected to the output end of the electric rod 471, and the first closed ring 485 can close the through hole 484. A second closed ring 486 is fixedly connected to the top of the storage cylinder 451, and the second closed ring 486 can close the connecting pipe 446.

[0066] Specifically, in the initial state, the second closed ring 486 is located at the lower side of the connecting tube 446, and the first closed ring 485 closes the through hole 484; when the hot air continuously enters the plastic particles through the connecting tube 446 for a period of time, the electric rod 472 is started, and the output end of the electric rod 472 contracts, so that the first closed ring 485 and the second closed ring 486 move upward, so that the through hole 484 is opened and the connecting tube 446 is closed, so that the gas in the air cavity 415 enters the connecting cavity 482 through the through hole 484, and then enters the auxiliary cavity 481 through the connecting cavity 482 and the connecting groove 483. After the hot air is supplied for a period of time, the electric rod 472 is reset, the through hole 484 is closed, and the connecting tube 446 is opened.
