DETAILED DESCRIPTION

[0028] refer to Figure 1 , 2, 3, 5, 7, 9 and 11, detailed description of the embodiment of recycling waste plastics for reuse and processing into plastic films through calendering:

[0029] A plastic recycling calendering film forming device, comprising a barrel Ⅰ11 with two through holes Ⅰ12 symmetrically arranged at the bottom, a ring frame Ⅰ13 fixedly connected to the middle of the barrel Ⅰ11 and a ring frame Ⅱ14 outside the barrel Ⅰ11, a ring plate Ⅰ21 rotatably connected between the ring frame Ⅰ13 and the barrel Ⅰ11, two push plates Ⅰ22 fixedly connected to the lower part of the ring plate Ⅰ21, a ring plate Ⅱ24 rotatably connected between the ring frame Ⅱ14 and the barrel Ⅰ11, two push plates Ⅱ25 fixedly connected to the lower part of the ring plate Ⅱ24, a heating frame Ⅰ34 fixedly connected to the outer part of the barrel Ⅰ11, and a heating frame Ⅱ3 fixedly connected to the middle part of the barrel Ⅰ11. 3. A middle frame 17 is fixedly connected to the middle of the barrel Ⅰ11, and a spiral frame 32 corresponding to the two through holes Ⅰ12 is rotatably connected to the middle frame 17. A mounting plate 51 is fixedly connected to the lower part of the barrel Ⅰ11, and two pairs of cylinders Ⅰ61 are fixedly connected to the mounting plate 51. A calendering frame 62 is fixedly connected to the cylinder rod of each pair of cylinders Ⅰ61. A calendering tube Ⅰ63 and a calendering tube Ⅱ64 are rotatably connected to the two calendering frames 62. The calendering tube Ⅰ63 and the calendering tube Ⅱ64 rotate synchronously in opposite directions. Both sides of the calendering tube Ⅰ63 and the calendering tube Ⅱ64 are rotatably connected and communicated with an externally arranged coolant supply device.

[0030] Bucket Ⅰ11 is used to load waste plastics and newly added materials for melting. More and more plastics are used in life, and the recycling of waste plastics can reduce environmental pollution while saving resources and reducing costs. At the same time, it can also speed up the processing speed of plastic products. The recycled plastics need to be cleaned, dried, classified and crushed before recycling the waste plastics. The two through holes Ⅰ12 are mainly used to discharge the melted plastic in barrel Ⅰ11, in preparation for subsequent calendering into plastic film processing. Ring frame Ⅰ13 can limit the ring plate Ⅰ21 for stable rotation, and the ring plate Ⅰ21 can drive the two push plates Ⅰ22 to rotate. Ring frame Ⅱ14 can limit the ring plate Ⅱ24 for stable rotation, and the ring plate Ⅱ24 can drive the two push plates Ⅱ2 5 is rotated, and the materials are melted and mixed in the space in the barrel Ⅰ11 separated by the two push plates Ⅰ22 and the two push plates Ⅱ25. The two spiral racks 32 are respectively fixedly connected to the output shafts of the corresponding reduction motors Ⅰ, and the two reduction motors Ⅰ are fixedly connected to the middle frame 17. The two reduction motors Ⅰ are started, and the output shafts of the two reduction motors Ⅰ drive the two spiral racks 32 to rotate and push the plastic to move, thereby achieving mutual mixing of the materials. The movement of the two push plates Ⅰ22 and the two push plates Ⅱ25 can also be coordinated to push the plastic to move in a large range. The rotation of the two spiral racks 32 ensures that the plastic is fully mixed, and after the plastic is mixed, the two spiral racks 32 can be rotated to push the plastic to be discharged from the two through holes Ⅰ12. The two push plates Ⅰ The movement of the two push plates Ⅰ22 and the two push plates Ⅱ25 can push the melted and mixed plastics to accumulate, and accumulate them to the position pushed by the two through holes Ⅰ12 for unloading, fully push the materials for unloading, and prevent the residual accumulation of plastic materials. When the two push plates Ⅰ22 and the two push plates Ⅱ25 move to adjust the space for mixing the waste plastics, they can adjust the pressure when the plastics are melted and mixed, and can fully compress the bubbles generated when the plastics are mixed through the change in pressure, thereby improving the quality of the plastic film processed during the subsequent calendering of the materials. The heating frame Ⅰ34 and the heating frame Ⅱ33 are both connected to the external heating furnace, and the high-temperature steam is provided to the heating frame Ⅰ34 and the heating frame Ⅱ33 through the external heating furnace. The material in Ⅰ11 is heated by plastic, so that the recycled waste plastic is completely melted, and the high-temperature steam can flow from the heating frame Ⅰ34 and the heating frame Ⅱ33 back to the external heating furnace to realize circulation, so that the temperature of the melted plastic is ensured by the circulating high-temperature steam, and the waste plastic can be mixed with the newly added material, and the waste plastic can be recycled and processed again at the same time. The completely melted and mixed materials can flow out from the two through holes Ⅰ12 for unloading and fall on the calendering tube Ⅰ63 and the calendering tube Ⅱ64 at the lower end. The mixed plastic is fully calendered by the calendering tube Ⅰ63 and the calendering tube Ⅱ64, and the plastic is extruded into a plastic film, and then the process of processing the plastic film using the waste plastic is realized by cooling and shaping.The cooling liquid is supplied to one side of the calender tube I63 and the calender tube II64 through an externally arranged cooling liquid supply device. The cooling liquid flows through the calender tube I63 and the calender tube II64 to exchange heat with the extruded plastic, thereby cooling and shaping the formed plastic film while the extruded plastic is being formed into a plastic film. At the same time, there is a temperature difference with the formed plastic, which can effectively cool the contacting plastic material, and then the plastic material is cooled from the outside to the middle to prevent the plastic material from sticking or adhering to the calender tube I63 and the calender tube II64. The cylinder rods of multiple cylinders Ⅰ61 can also be started to extend or retract at the same time, and the cylinder rods of multiple cylinders Ⅰ61 drive the two calendering racks 62 to rise and fall. The two calendering racks 62 can drive the calendering tubes Ⅰ63 and calendering tubes Ⅱ64 to rise and fall to adjust the distance between the axis and the bottom of the barrel Ⅰ11, so as to adjust the time for the plastic material flowing out of the barrel Ⅰ11 to be calendered between the calendering tubes Ⅰ63 and calendering tubes Ⅱ64, thereby adjusting the temperature of the plastic material calendered by the calendering tubes Ⅰ63 and calendering tubes Ⅱ64, and preventing the calendered plastic from being too high in temperature, which is not convenient for calendering into plastic film and affects the effect of calendering to manufacture plastic film.

[0031] refer to Figure 1 , 8 9, detailed description of the embodiment of controlling the plastic discharge in the barrel Ⅰ11 and dispersing the pre-processing of the calendered plastic film:

Two feeding pipes 42 are fixedly connected to the ring plate Ⅲ41. The ring plate Ⅲ41 is provided with a through hole Ⅱ corresponding to the two feeding pipes 42. The two through holes Ⅱ and the two through holes Ⅰ12 are located on the same circumference. The lower parts of the two feeding pipes 42 are fixedly connected to a circular tube 43. The two feeding pipes 42 are connected to the circular tube 43. The lower part of the circular tube 43 is fixedly connected to a forming frame 44. The outlet of the forming frame 44 is located between the calendering tube Ⅰ63 and the calendering tube Ⅱ64.

[0033] When the waste plastics are heated, melted and mixed in the barrel Ⅰ11, the through hole Ⅱ on the ring plate Ⅲ41 is staggered with the two through holes Ⅰ12, so as to cover the two through holes Ⅰ12 and prevent the melted and mixed plastics from leaking, thereby maintaining the temperature in the barrel Ⅰ11 and fully melting and mixing the waste plastics. After the waste plastics are melted and mixed, the ring plate Ⅲ41 is driven to rotate until the through hole Ⅱ on the ring plate Ⅲ41 coincides with the two through holes Ⅰ12, and the waste plastics are discharged through the two through holes Ⅰ12. The mixed plastics are concentrated at the position close to the two through holes Ⅰ12 through the movement of the two push plates Ⅰ22 and the two push plates Ⅱ25 for sufficient discharge, and after flowing into the two discharge pipes 42 at the lower end, they flow into the circular pipe 43, and then flow out from the forming frame 44. The discharge port of the forming frame 44 is rectangular, which can The plastic that flows out can be constrained to be formed into a plastic film, and then the plastic that flows out of the molding frame 44 is processed into a plastic film through the calendering tube Ⅰ63 and the calendering tube Ⅱ64 again. The cylinder rods of multiple cylinders Ⅰ61 can drive the two calendering racks 62 to rise and fall. The two calendering racks 62 can drive the calendering tube Ⅰ63 and the calendering tube Ⅱ64 to rise and fall to adjust the distance between the axis and the bottom of the barrel Ⅰ11, so as to adjust the distance between the calendering tube Ⅰ63 and the calendering tube Ⅱ64 and the discharge port of the molding frame 44, and then the position of the calendering tube Ⅰ63 and the calendering tube Ⅱ64 can be adjusted to ensure that the calendering tube Ⅰ63 and the calendering tube Ⅱ64 can timely calender the plastic that flows out of the discharge port of the molding frame 44, so as to prevent the plastic that flows out of the discharge port of the molding frame 44 from accumulating or reducing, and failing to calender a continuous plastic film.

[0034] refer to Figure 1 , 9 10, detailed description of the embodiment of dispersing the plastic in the circular tube 43 for unloading to facilitate molding a complete plastic film:

[0035] The circular tube 43 is rotatably connected with a pusher rack 46, on which spiral blades are symmetrically arranged. The pusher rack 46 is fixedly connected to the output shaft of the reduction motor II, which is fixedly connected to the circular tube 43. When the reduction motor II is started, the output shaft of the reduction motor II drives the pusher rack 46 to rotate. The spiral blades under the rotation of the pusher rack 46 push the plastics flowing out of the two feed pipes 42 to be fully dispersed into the circular tube 43 for dispersion, ensuring that the plastics flow out of the discharge port of the forming frame 44 evenly and are formed into plastic films, which is convenient for the calendering tubes I 63 and II 64 at the bottom to be calendered. The symmetrically arranged spiral blades can ensure that the plastics flowing out of the feed pipe 42 under rotation fully flow to the middle, rather than unilateral movement, which is conducive to the dispersion of materials and the processing of plastic films.

[0036] refer to Figure 1 , 8 9, detailed description of the embodiment of driving the ring plate III 41 to rotate to realize whether the material in the barrel I 11 is discharged:

[0037] The ring plate III 41 is fixedly connected with a gear ring III 45, and two slideways 52 are symmetrically arranged on the mounting plate 51. A rack frame 53 for driving the gear ring III 45 to rotate is slidably connected in each slideway 52, and a cylinder II 54 for driving the corresponding rack frame 53 to slide back and forth is fixedly connected to the end of each slideway 52.

When reduction motor III is started, reduction motor III drives gear V67 to rotate, gear V67 meshes with driving gear III65 to rotate, gear III65 meshes with driving gear IV66 to rotate, gear III65 drives calendering tube I63 to rotate, gear IV66 drives calendering tube II64 to rotate, thereby realizing synchronous reverse rotation of calendering tube I63 and calendering tube II64, thereby realizing calendering of the plastic film supplied from the upper part and processing of the plastic film. When calendering the plastic, the multiple ridges on calendering tube I63 cooperate with the multiple grooves on calendering tube II64 to press the plastic into a folded plastic film. The foldable plastic film can be formed into a plastic thicker than the plastic film at the folded position in the length direction when the plastic film is used, thereby processing a plastic film with strong tensile strength.

[0048] The two calendering frames 62 are fixedly connected with a cooling frame 71. A rectangular hole for accommodating the film is provided in the middle of the cooling frame 71. The cooling frame 71 is hollow inside and is connected to an externally arranged cooling liquid supply device. The plastic film calendered by the calendering tube I 63 and the calendering tube II 64 passes through the rectangular hole of the cooling frame 71 and then passes through the lower part of the guide rod 73 to guide the plastic film. The cooling liquid is supplied from one side of the cooling frame 71 through the externally arranged cooling liquid, and flows back to the externally arranged cooling liquid from the other side to realize the circulation of the cooling liquid.
