[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] This invention provides, for example Figure 1-5 The plastic film production device based on nano copper oxide antiviral masterbatch shown includes a base 1, a feeding assembly on the top of the base 1, a feeding box 15, a feeding hopper 16 connected to the top of the feeding box 15, a crushing assembly in the inner cavity of the feeding box 15, a crushing motor 17 fixedly installed at the front and rear ends of one side of the feeding box 15, the output shaft of the crushing motor 17 passes through the feeding box 15 and extends to the inner cavity of the feeding box 15 where a crushing roller 18 is fixedly installed, and the end of the crushing roller 18 away from the crushing motor 17 is supported by a bearing on the inner wall of the feeding box 15.

[0041] With the setting of the feeding component, the inner cavity of the feeding box 15 is equipped with a crushing component. When the raw material enters the inner cavity of the feeding box 15 through the feeding hopper 16, the user can turn on the crushing motor 17 through the external controller. The output shaft of the crushing motor 17 drives two sets of crushing rollers 18 to rotate simultaneously, and crush the raw material particles in a secondary manner to reduce the particle size of the raw material particles and increase the uniformity of subsequent mixing.

[0042] like Figure 7-9 As shown, both sets of crushing rollers 18 include hollow columns 46 and toothed holes opened on the hollow columns 46. A first drive motor 38 is fixed on the inner side wall of the hollow column 46. A rotating column 39 is fixed at one end of the output shaft of the first drive motor 38. A connecting rod 41 is hinged to the surface of the rotating column 39 through a hinge block 40. A collar 42 is provided at one end of the connecting rod 41. A crossbar 43 is fixed on the crushing teeth of the crushing roller 18. The collar 42 is slidably fitted on the crossbar 43.

[0043] A second drive motor 44 is provided on the side wall inside the hollow column 46 opposite to the first drive motor 38. One end of the output shaft of the second drive motor 44 is fixed with a turn wheel 45 for turning the direction of the crushing teeth. A guide rod for sliding limit of the crushing teeth is provided inside the hollow column 46.

[0044] Furthermore, the crushing teeth are configured with hexagonal cross-sections, and each crushing tooth is equipped with an arc-shaped cutter head, a serrated cutter head, and a rectangular cutter head, which are used to switch between different cutter heads according to different crushing requirements during crushing.

[0045] Since different shapes of cutters are needed to achieve better crushing results when crushing different materials, the above design allows the first drive motor 38 to drive the rotating column 39 to rotate when the cutter shape needs to be changed. Due to the hinged connection of the connecting rod 41 and the guiding action of the guide rod, the crushing teeth can be completely pulled into the hollow column 46. Then, the second drive motor 44 drives the actuating wheel 45 to rotate 120°, and the actuating wheel 45 drives the crushing teeth to rotate 120°, thereby changing the cutter shape as needed. Then, the first drive motor 38 is reversed so that the crushing teeth after changing the cutter shape pass through the tooth holes on the hollow column 46, realizing the cutter switching.

[0046] A mixing component is installed at the bottom of the feeding component. The mixing component includes a mixing box 19 fixedly installed at the bottom of the feeding box 15. Discharge troughs 20 are provided at the top of the mixing box 19 and the bottom of the feeding box 15. A stirring component is provided in the inner cavity of the mixing box 19. The stirring component includes a stirring motor 21 fixedly installed at the bottom of the mixing box 19. The output shaft of the stirring motor 21 passes through the mixing box 19 and extends to the inner cavity of the mixing box 19. A rotating rod 22 is fixedly installed thereon. A stirring rod 23 is fixedly installed on the surface of the rotating rod 22.

[0047] With the mixing component in place, the raw materials, after being crushed, fall into the inner cavity of the mixing box 19 through the discharge chute 20. At this time, the user can turn on the stirring motor 21 through the external controller. The output shaft of the stirring motor 21 drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the stirring rod 23 to rotate. The rotation of the stirring rod 23 can stir and mix the raw materials in the inner cavity of the mixing box 19 to improve the uniformity of the raw material mixing. In this embodiment, the stirring rod 23 is arranged symmetrically with the rotating rod 22 as the center. Compared with the traditional stirring rod 23, it can further improve the uniformity of the material mixing inside the mixing box 19. Moreover, the set of stirring rods 23 at the bottom is at the same level as the telescopic tube 26. When the material is discharged through the telescopic tube 26, the set of stirring rods 23 at the bottom can stir the material at the opening of the telescopic tube 26, which can prevent the material inside the mixing box 19 from being blocked at the opening of the telescopic tube 26.

[0048] The bottom of the mixing assembly is provided with a lifting assembly, which includes a lifting motor 30 and a threaded tube 31. The lifting motor 30 is fixedly installed at the bottom of the base 1, and the threaded tube 31 is supported by a bearing on the surface of the base 1. The inner cavity of the threaded tube 31 is threadedly connected to a threaded rod 32. The top end of the threaded rod 32 passes through the threaded tube 31 and extends to the outside of the threaded tube 31 and is fixedly connected to the bottom of the mixing box 19. The bottom end of the threaded rod 32 passes through the threaded tube 31 and extends to the outside of the threaded tube 31. The output shaft of the drive motor 6 passes through the base 1 and extends to the outside of the base 1 and is fixedly installed with a drive gear 33. The surface of the drive gear 33 is meshed with a driven gear 34, and the driven gear 34 is installed on the surface of the threaded tube 31.

[0049] With the lifting assembly in place, after the raw materials are mixed, the user can turn on the lifting motor 30 via an external controller. The output shaft of the lifting motor 30 drives the drive gear 33 to rotate, the rotation of the drive gear 33 drives the driven gear 34 to rotate, the rotation of the driven gear 34 drives the threaded tube 31 to rotate, the rotation of the threaded tube 31 drives the threaded rod 32 to move, and the movement of the threaded rod 32 drives the mixing box 19 to move upward. In this embodiment, four sets of threaded rods 32 are set and installed at the four corners of the bottom of the mixing box 19. When the mixing box 19 is lifted and lowered, the four sets of threaded rods 32 move upward at the same time, which can improve the stability of the movement of the mixing box 19.

[0050] A detachable raw material conveying assembly is installed between the mixing assembly and the raw material melting assembly. The detachable raw material conveying assembly includes a telescopic pipe 26 and a conveying pipe 27. The telescopic pipe 26 is connected to the surface of the mixing box 19 and a control valve is installed on the telescopic pipe 26. The conveying pipe 27 is connected to the top of the melting tank 2. A connecting pipe 28 is supported by a bearing at one end of the conveying pipe 27. The inner wall of the connecting pipe 28 is threadedly connected to one end of the telescopic pipe 26.

[0051] After the mixing tank 19 moves to the position where the telescopic tube 26 is aligned with the conveying tube 27, it stops moving. Then, the user pulls the telescopic tube 26 outward so that the inner tube of the telescopic tube 26 is aligned with one end of the conveying tube 27. Then, the user can rotate the connecting tube 28. The rotation of the connecting tube 28 will cause its inner wall to be threadedly connected to one end of the inner tube of the telescopic tube 26, thereby connecting the telescopic tube 26 and the conveying tube 27 together. Then, the user opens the control valve on the telescopic tube 26 to convey the raw material in the inner cavity of the mixing tank 19 to the inner cavity of the melting tank 2.

[0052] A raw material melting assembly is provided on the top of the base 1 and on one side of the lifting assembly. The raw material melting assembly includes a melting tank 2 located above the base 1. A far-infrared heating plate 3 is fixedly installed in the inner cavity of the melting tank 2. A protective cover 4 is fixedly installed in the inner cavity of the melting tank 2 and on the outside of the far-infrared heating plate 3. Connecting blocks 5 are fixedly installed on both sides of the melting tank 2. A drive assembly is fixedly installed on the side of one set of connecting blocks 5 away from the melting tank 2. A cleaning assembly is provided on the inner cavity of the melting tank 2 and the surface of the protective cover 4. The melting tank 2 is fixed to the base 1 by a support assembly.

[0053] The drive assembly includes a drive motor 6, a drive gear 7, a connecting belt 8, a driven gear 9, and a drive disc 10. The drive motor 6 is fixedly mounted on the top of the base 1. The drive gear 7 is fixedly connected to the output shaft of the drive motor 6. The drive disc 10 is fixedly mounted on one side of the connecting block 5. The driven gear 9 is mounted on the surface of the drive disc 10. The drive gear 7 and the driven gear 9 are connected by the connecting belt 8.

[0054] With the raw material melting assembly in place, after the raw material is delivered to the inner cavity of the melting tank 2, the user can disconnect the telescopic tube 26 and the conveying tube 27. The conveying tube 27 is also equipped with a control valve. After disconnecting it, the user can tighten the control valve on the conveying tube 27 to prevent the raw material from leaking out of the conveying tube 27 during the rotation of the melting tank 2. At this time, the user can open the far-infrared heating plate 3 through the external controller to heat and melt the raw material inside the melting tank 2.

[0055] Then, the user turns on the drive assembly through the external controller. The output shaft of the drive motor 6 drives the drive gear 7 to rotate. The rotation of the drive gear 7 drives the driven gear 9 to rotate through the connecting belt 8. The rotation of the driven gear 9 drives the drive disc 10 to rotate. The rotation of the drive disc 10 drives the connecting block 5 to rotate. The rotation of the connecting block 5 drives the melting tank 2 to rotate, thereby tumbling and stirring the raw materials inside the melting tank 2 to improve its heating uniformity and improve the melting effect.

[0056] The cleaning assembly includes a cleaning rod 11 disposed in the inner cavity of the fusion tank 2. Both ends of the cleaning rod 11 are fixedly installed with connecting rods 12. The end of the connecting rod 12 away from the cleaning rod 11 is fixedly installed with a drive rod 13. One set of drive rods 13 passes through the fusion tank 2 and the connecting block 5 in sequence and extends to the outside of the connecting block 5. The other set of drive rods 13 passes through the fusion tank 2, the connecting block 5 and the drive plate 10 in sequence and extends to the outside of the drive plate 10. Two sets of mounting rods 14 are installed on the top of the base 1. One end of each set of drive rods 13 is fixedly installed with a bearing on the surface of the mounting rod 14.

[0057] By setting up the cleaning component, when the melting tank 2 rotates, since the cleaning rod 11 is fixed, the cleaning rod 11 can clean the raw material adhering to the surface of the protective cover 4 during the rotation of the melting tank 2. In this embodiment, the cleaning rod 11 can clean the raw material adhering to the surface of the protective cover 4. When the melting tank 2 rotates, the raw material will adhere to the surface of the protective cover 4. When the raw material adheres to the surface of the protective cover 4 for a long time, it will affect the heating effect of the far-infrared heating plate 3 on the raw material in the melting tank 2. In this embodiment, the cleaning rod 11 is located in the middle of the melting tank 2, and the height of the cleaning rod 11 is higher than the height of the raw material in the melting tank 2. It can clean the protective cover 4 part outside the raw material during the rotation of the melting tank 2. The far-infrared heating plate 3 always heats the material in the melting tank 2 through its position above.

[0058] Example 2

[0059] The difference between this embodiment 2 and embodiment 1 is that the support assembly includes a support ring 35 supported by a bearing on the surface of the fusion tank 2, a support column 36 fixedly installed on the surface of the support ring 35, and the bottom of the support column 36 fixedly connected to the top of the base 1.

[0060] With the support components in place, the support ring 35 is supported on the outside of the fusion tank 2, and the support ring 35 is fixedly connected to the base 1 by the support column 36. The support column 36 can fix the position of the support ring 35, thereby fixing the position of the fusion tank 2.

[0061] A sealing ring 37 is fitted on the surface of the drive rod 13 and inside the fusion tank 2. One side of the sealing ring 37 is fixedly installed to the inner wall of the fusion tank 2. A sealing gasket 29 is fixedly installed at one end of the conveying pipe 27 and inside the connecting pipe 28. The end of the sealing gasket 29 away from the conveying pipe 27 is in contact with one end of the telescopic pipe 26.

[0062] By setting the sealing ring 37, the connection between the drive rod 13 and the melting tank 2 can be sealed to prevent the raw material inside the melting tank 2 from leaking out from the connection between the drive rod 13 and the melting tank 2. By setting the sealing gasket 29, the connection between the telescopic tube 26 and the conveying tube 27 can be sealed.

[0063] The mixing box 19 is provided with a positioning assembly. The positioning assembly includes a positioning plate 24 located in the inner cavity of the mixing box 19, a top of the rotating rod 22 and a bottom bearing support of the positioning plate 24, and a positioning rod 25 fixedly installed on the surface of the positioning plate 24. The end of the positioning rod 25 away from the positioning plate 24 is fixedly connected to the inner wall of the mixing box 19.

[0064] By setting up the positioning components, the positioning plate 24 and the positioning rod 25 work together to fix the top of the rotating rod 22 and prevent the rotating rod 22 from shifting during rotation.

[0065] Example 3

[0066] like Figure 6 As shown, the difference between this embodiment 3 and embodiments 1 and 2 is that this embodiment also discloses a production process for a plastic film production device based on nano-copper oxide antiviral masterbatch, including the following steps:

[0068] S2, Raw material mixing: The crushed raw materials are discharged into the inner cavity of the mixing box 19 through the discharge chute 20, and the user opens the stirring component to mix the raw materials;

[0069] S3. Adjusting the height: After the raw materials are mixed, the user opens the lifting component to raise the height of the mixing box 19 to above the melting tank 2;

[0070] S4. Raw material conveying: After raising the height of the mixing box 19, the user splices the detachable raw material conveying components together, so that the telescopic pipe 26 is connected to the conveying pipe 27, and then opens the control valve to discharge the raw material in the mixing box 19 into the melting tank 2.

[0071] S5. Raw material fusion: After the raw material enters the inner cavity of the fusion tank 2, the user turns on the drive component and the far-infrared heating plate 3. The operation of the far-infrared heating plate 3 can heat and fuse the raw material inside the fusion tank 2. The drive component can drive the fusion tank 2 to rotate, so as to improve the uniformity of heating of the raw material inside the fusion tank 2.

[0072] S6 Cleaning: During the raw material melting process, since the cleaning rod 11 is fixed, it can clean the raw material adhering to the surface of the protective cover 4 during the rotation of the melting tank 2.
