Description

Technical Field

[0001] This application relates to the field of color masterbatch processing technology, and more specifically, to color masterbatch processing equipment based on plastic recycling. Background Technology

[0002] Color masterbatch processing technology based on plastic recycling is a technology that transforms waste plastics (such as polypropylene, polyethylene, etc.) into functional materials that can be used to color plastic products through modification, coloring, and granulation processes. Currently, after plastics are recycled, they need to be cleaned, crushed, and granulated to form plastic granules, which are then fed into an extruder to mix with pigments to regenerate color masterbatch. The extrusion quality of the plastic granules is related to the final processing quality of the color masterbatch, such as the size of the plastic granules and the content of impurities (which may come from charred material inside the extruder). Therefore, it is necessary to clean the inside of the extruder.

[0003] In related technologies, in order to facilitate efficient cleaning of extrusion screws, for example, the prior art patent with publication number CN117047933B provides a plastic particle production extrusion molding device. This device achieves full automation of screw installation, disassembly, and cleaning through the cooperation of a pull mechanism and a telescopic gripper. It not only saves a lot of manpower and resources in the screw disassembly and installation steps, but also makes the cleaning process simpler, thereby improving production efficiency.

[0004] While the existing technical solutions described above facilitate cleaning by pulling the screw, they are not convenient for cleaning the inner wall of the extruder. Furthermore, the generated plastic particles are not easily transported back into the extruder to mix with pigments, requiring the plastic particles to be transferred again or another extruder to be used for processing, which increases processing costs and reduces processing efficiency.

[0005] In view of this, we propose a color masterbatch processing equipment based on plastic recycling. Summary of the Invention

DETAILED DESCRIPTION

[0073] The present application will be further described in detail below with reference to the accompanying drawings.

[0074] REFERENCE Figures 1-17The embodiment of the application discloses a color master batch processing device based on plastic recycling, which comprises a supporting seat 1, an extrusion barrel 2, an extrusion assembly 3, a cleaning barrel 4 and a cleaning assembly 5. The extrusion barrel 2 is rotationally arranged on the top of the supporting seat 1 and is supported by external force to keep a horizontal state. The extrusion assembly 3 is arranged on the side of the extrusion barrel 2 away from the output end. The cleaning barrel 4 is fixedly arranged on the top of the supporting seat 1 and is located on one side of the extrusion barrel 2. The cleaning assembly 5 is arranged outside the extrusion assembly 3 and is located on the side of the extrusion barrel 2 away from the cleaning barrel 4. The extrusion assembly 3 comprises a first shaft sleeve 31 which is detachably arranged inside the extrusion barrel 2. An extrusion rod 32 is rotationally arranged inside the first shaft sleeve 31. The extrusion rod 32 is located inside the extrusion barrel 2 and is used for extruding plastic particles. The extrusion rod is a double helix rod. The first shaft sleeve 31 is provided with the cleaning assembly 5 outside the first shaft sleeve 31 for cleaning the inner wall of the extrusion barrel 2. The first shaft sleeve 31 is driven by external force to move along the Y-axis direction, so as to move the extrusion rod 32 out of / into the inside of the extrusion barrel 2. The extrusion barrel 2 automatically triggers a downward tilting action after the extrusion rod 32 is moved out. The first shaft sleeve 31 is driven by external force to move along the X-axis direction, so as to coaxially align the extrusion rod 32 with the cleaning barrel 4. The first shaft sleeve 31 synchronously drives the cleaning assembly 5 to be coaxially aligned with the extrusion barrel 2.

[0075] When the recycled plastic particles are processed, impurities and residues are adhered to the inner wall of the extrusion barrel 2 and the surface of the extrusion rod 32 after the plastic particles are mixed and extruded by the extrusion rod 32 inside the extrusion barrel 2. At this time, the first shaft sleeve 31 is driven to move along the Y-axis direction, so as to drive the extrusion rod 32 to be extracted out of the inside of the extrusion barrel 2, so as to detach the extrusion barrel 2 and the extrusion rod 32 from each other. The first shaft sleeve 31 is driven to move along the X-axis direction by a certain distance, so as to drive the first shaft sleeve 31 to drive the extrusion rod 32 to be aligned with the cleaning barrel 4, so as to prepare to clean the extrusion rod 32. Meanwhile, the first shaft sleeve 31 drives the cleaning assembly 5 outside to be coaxially aligned with the extrusion barrel 2, so as to prepare to clean the inner wall of the extrusion barrel 2. At this time, the extrusion barrel 2 automatically triggers a tilting action, so as to make the side of the extrusion barrel 2 away from the output end to be downwardly tilted, so as to be coaxially aligned with the cleaning assembly 5 in the tilted state. Then, the first shaft sleeve 31 is driven to move along the Y-axis, so as to drive the first shaft sleeve 31 to drive the extrusion rod 32 to be inserted into the inside of the cleaning barrel 4, and drive the cleaning assembly 5 to be located in the inside of the extrusion barrel 2, so as to clean the extrusion barrel 2 and the extrusion rod 32 at the same time. Meanwhile, the extrusion barrel 2 is in a tilted state during the cleaning process, so as to automatically discharge the liquid in the inside during the cleaning and flushing, and facilitate the drying of the inside of the extrusion barrel 2. After the cleaning and drying, the extrusion rod 32 is installed into the inside of the extrusion barrel 2, so as to mix and extrude the extruded plastic particles and pigments by the extrusion barrel 2 and the extrusion rod 32 to generate color master batches meeting the requirements. Meanwhile, the device can continue to process the color master batches by the convenient cleaning, and additional processing devices are not needed, so as to reduce the processing cost of the color master batches.

[0076] Referring to Figure 2 and Figure 11 , the top of the extrusion barrel 2 is fixedly provided with a feeding hopper 21, and the output end of the extrusion barrel 2 is fixedly provided with a cooling die head 22. An outside of the output end of the extrusion barrel 2 is fixedly provided with a pelletizing assembly 23 for cutting the plastic strip output by the cooling die head 22. Specifically, the pelletizing assembly 23 comprises a safety cover 231 fixedly provided outside the extrusion barrel 2, a drive shaft 232 rotatably provided inside the safety cover 231, a cutter 233 fixedly provided outside the drive shaft 232, the cutter 233 being located at the output end of the cooling die head 22, a first motor 234 fixedly provided inside the safety cover 231 for driving the drive shaft 232, and a pipe joint 221 fixedly provided outside the cooling die head 22 for connecting a liquid cooling system to cool the extruded material at the output end of the cooling die head 22 (which is prior art and will not be described in detail here).

[0077] Specifically, during processing, plastic particles are added into the inside of the extrusion barrel 2 through the feeding hopper 21, and finally extruded through the cooling die head 22 at the output end of the extrusion barrel 2. The output end of the cooling die head 22 is provided with a plurality of hole-shaped channels. The extruded material is cooled into a plastic strip when passing through the output end of the cooling die head 22. The drive shaft 232 is driven to rotate at high speed by the first motor 234, so that the drive shaft 232 drives the cutter 233 to cut the extruded plastic strip at the output end of the cooling die head 22. The cutter 233 is isolated from the working range by the safety cover 231 during high-speed operation to ensure safety.

[0078] Referring to Figure 3 , Figure 4 and Figure 5 , the top of the support base 1 is fixedly provided with a support column 11 near one side of the output end of the extrusion barrel 2. The top of the support column 11 is fixedly provided with a support shaft 12. The other side of the support base 1 is symmetrically fixedly provided with a support seat 13 for supporting the extrusion barrel 2. The top of the support base 1 is also rotatably provided with a first push rod 14 for driving the extrusion barrel 2 to rotate. The bottom of the extrusion barrel 2 is fixedly provided with a machine frame 28. The machine frame 28 is rotatably connected with the support shaft 12 through a bearing seat 29. The bottom of the machine frame 28 is also provided with a horizontal shaft 210 rotatably connected with a driving end of the first push rod 14. The top of the extrusion barrel 2 outside is fixedly provided with a positioning block 211 corresponding to the support seat 13. One side of the positioning block 211 near the support seat 13 is a slope. The slope of the positioning block 211 is attached to the top of the support seat 13 in the inclined state of the extrusion barrel 2, for limiting the inclination angle of the extrusion barrel 2. The top of the support base 1 is also fixedly provided with a support beam 15 for supporting the cleaning barrel 4.

[0079] Because the volume and mass of the extrusion barrel 2 are large (especially for large equipment), when the extrusion barrel 2 is switched between the horizontal and inclined states, the horizontal shaft 210 at the bottom of the frame 28 is driven by the first push rod 14 at the top of the support base 1, so that the frame 28 drives the extrusion barrel 2 to rotate. In order to ensure the stability of the inclination angle of the extrusion barrel 2, the bottom inclined surface of the positioning block 211 on the outer side is flush and fitted with the top of the support base 13 when the extrusion barrel 2 is inclined at a certain angle, so that the extrusion barrel 2 is fixed in the inclined cleaning state by the support base 13, preventing the angle of the extrusion barrel 2 from being unstable during cleaning and interfering with the operation of the cleaning assembly 5.

[0080] In order to ensure the stability of the horizontal state of the extrusion barrel 2, with reference to Figure 5 、 Figure 6 、 Figure 7 and Figure 10 , the extrusion assembly 3 further comprises a moving trolley 34 for driving the first shaft sleeve 31 to move. The moving trolley 34 is internally provided with a power device (such as a motor and a gear box) for driving the extrusion rod 32 to rotate. The moving trolley 34 is fixedly provided with a positioning arm 35 on both sides corresponding to the positioning block 211, and the positioning arm 35 is located between the support base 13 and the positioning block 211, for limiting the levelness of the extrusion barrel 2. The support base 13 is fixedly provided with a limiting table 16 at the top, and the limiting table 16 is provided with a V-shaped groove at the top. The limiting table 16 and the bottom of the positioning arm 35 are in sliding fit.

[0081] When the first push rod 14 drives the extrusion barrel 2 to be in the horizontal state, the first shaft sleeve 31 is driven by the moving trolley 34 to move axially, so that the first shaft sleeve 31 drives the extrusion rod 32 to move towards the inside of the extrusion barrel 2, in order to assemble the extrusion rod 32 and the extrusion barrel 2. During the assembly process, the moving trolley 34 drives the positioning arm 35 on the outer side to move on both sides of the extrusion barrel 2 and between the positioning block 211 and the support base 13. Finally, the space between the two is filled by the positioning arm 35, so that the extrusion barrel 2 and the extrusion rod 32 maintain coaxiality during operation, ensuring the safety of use.

[0082] In order to realize the sealing of the butt joint of the extrusion rod 32 and the extrusion barrel 2, with reference to 1, Figure 4 、 Figure 7 、 Figure 9 and Figure 12The first end cover 33 is fixedly arranged outside the extrusion barrel 2. The sealing sleeve 24 is fixedly arranged on the side of the extrusion barrel 2 away from the output end. The coordinating hole 25 is arranged in the inner side of the sealing sleeve 24. The first sealing ring 26 and the fixing bolt 27 are fixedly arranged on the side of the sealing sleeve 24 away from the extrusion barrel 2. The first sealing ring 26 is coaxially arranged with the coordinating hole 25. The fixing bolt 27 is used for fixedly connecting the first end cover 33 and the sealing sleeve 24. The first sealing surface 251 is arranged in the inner side of the end of the coordinating hole 25 away from the first sealing ring 26. One end of the first shaft sleeve 31 is matched with the first sealing surface 251. The second sealing surface 331 is arranged in the inner side of the first end cover 33 corresponding to the first sealing ring 26. The second sealing ring 41 is fixedly arranged on the inserting end of the cleaning barrel 4 and matched with the first end cover 33. The water inlet pipe 42 is fixedly arranged on the top of the cleaning barrel 4. The water outlet pipe 43 is fixedly arranged on the bottom of the cleaning barrel 4. The ultrasonic generator is arranged on the inner wall of the cleaning barrel 4 and used for fully cleaning the extrusion rod 32.

[0083] When the mobile trolley 34 drives the first shaft sleeve 31 to be inserted into the sealing sleeve 24, the end of the first shaft sleeve 31 is finally matched with the first sealing surface 251 in the inner side of the coordinating hole 25 to form the first sealing structure, realizing the first sealing of the first shaft sleeve 31 and the sealing sleeve 24. At the same time, the second sealing surface 331 in the inner side of the first end cover 33 is matched with the first sealing ring 26 in the outer side of the sealing sleeve 24 to form the second sealing structure. Finally, the first end cover 33 and the sealing sleeve 24 are fixed by the fixing bolt 27. At this time, the first shaft sleeve 31 drives the mobile trolley 34 to be in a fixed state. The mobile trolley 34 drives the positioning arm 35 to be in a fixed state, so as to ensure the stability of the positioning arm 35 supporting the positioning block 211. When cleaning, the first shaft sleeve 31 is also matched with the inner side of the cleaning barrel 4. The second sealing surface 331 in the inner side of the first end cover 33 is matched with the second sealing ring 41, so as to prevent the cleaning liquid in the cleaning barrel 4 from leaking during the cleaning process. Specifically, when the cleaning barrel 4 cleans the extrusion rod 32, a certain amount of cleaning agent can be added into the cleaning barrel 4 through the water inlet pipe 42. The ultrasonic generator on the inner wall of the cleaning barrel 4 is used for cleaning the extrusion rod 32. The extrusion rod 32 can also be placed outside the cleaning barrel 4. After the more obvious impurities on the surface of the extrusion rod 32 are cleaned by using tools manually, the extrusion rod 32 is cleaned.

[0084] In order to realize that the first shaft sleeve 31 can move along the X and Y axes, with reference to Figure 8 and Figure 9, the bottom of the moving trolley 34 is slidably provided with a second guide rail 38 along the Y-axis direction, the bottom of the second guide rail 38 is fixedly provided with a bottom plate 310, and the bottom of the bottom plate 310 is fixedly provided with an automatic sliding block 311; the water tank 17 is fixedly arranged on the side of the support seat 1 away from the output end of the extrusion barrel 2, the first guide rail 18 is fixedly arranged on the top of the water tank 17 along the X-axis direction, the automatic sliding block 311 is slidably arranged on the outer side of the first guide rail 18, and the bottom plate 310 is provided with a lifting assembly 39 on the side close to the extrusion rod 32, for supporting the extrusion rod 32 after moving out; by moving the moving trolley 34 along the second guide rail 38, the first shaft sleeve 31 can be driven to move along the Y-axis direction, and in the moving process, the first shaft sleeve 31 and the extrusion rod 32 are supported by the lifting assembly 39 on the outer side of the bottom plate 310, so that the extrusion rod 32 is prevented from being damaged due to the length in the moving process, and the stability of the translation of the moving trolley 34 can be ensured.

[0085] Specifically, the lifting assembly 39 comprises a I-shaped wheel 391, and the I-shaped wheel 391 is rotatably arranged on the outer side of a wheel frame 392, and the wheel frame 392 is located on the top of the bottom plate 310. The bottom plate 310 is fixedly provided with a second push rod 393 for driving the wheel frame 392 to move up and down. When the first shaft sleeve 31 is pulled out to a certain length, the first shaft sleeve 31 is still located on the inner side of the coordination hole 25, then the wheel frame 392 is driven to move up by the second push rod 393, so that the I-shaped wheel 391 on the inner side of the wheel frame 392 is attached to the bottom of the first shaft sleeve 31. As the first shaft sleeve 31 is gradually pulled out of the coordination hole 25, the I-shaped wheel 391 is driven to move up by the second push rod 393 to a certain height, so that the I-shaped wheel 391 is located at the bottom of the extrusion rod 32. Finally, the I-shaped wheel 391 supports the extrusion end of the extrusion rod 32 to ensure the stability of the extrusion rod 32 and the moving trolley 34, and then the automatic sliding block 311 is driven to slide along the first guide rail 18 to drive the second guide rail 38 to move, so that the second guide rail 38 drives the moving trolley 34 and the extrusion rod 32 to move close to the cleaning barrel 4. After the extrusion rod 32 is aligned with the cleaning barrel 4, the extrusion rod 32 is inserted into the inside of the cleaning barrel 4 by the moving trolley 34, so as to disassemble and clean the extrusion rod 32.

[0086] Referring to Figure 8 , Figure 9 and Figure 13The cleaning assembly 5 includes a second bushing 51 corresponding to the matching hole 25. A cleaning rod 52 for cleaning the inner wall of the extrusion cylinder 2 is rotatably disposed inside the second bushing 51. A second end cap 53 is fixedly disposed outside the second bushing 51. The second end cap 53 and the first sealing ring 26 are configured to cooperate. A liquid supply pipe 58 is fixedly disposed outside the second end cap 53. The output end of the liquid supply pipe 58 is located on the end face of the second bushing 51. A second motor 54 for driving the cleaning rod 52 to rotate is fixedly disposed outside the second end cap 53. A connecting seat 55 is fixedly disposed outside the second end cap 53. A slide rail 56 is fixedly disposed on the side of the connecting seat 55 near the extrusion assembly 3. A track plate 312 is fixedly disposed on the outer side of the base plate 310. The track plate 312 is inclined and coaxially aligned with the inclined extrusion cylinder 2. The track plate 312 and the slide rail 56 are slidably disposed. The connecting seat 55 moves synchronously under the drive of the moving trolley 34.

[0087] When the moving trolley 34 drives the extrusion rod 32 to align with the cleaning cylinder 4, the base plate 310 synchronously drives the track plate 312 to move along the X-axis, causing the track plate 312 to drive the connecting seat 55 to move synchronously, thereby driving the cleaning rod 52 to align coaxially with the extrusion cylinder 2. When the moving trolley 34 drives the extrusion rod 32 to move into the cleaning cylinder 4, the moving trolley 34 synchronously drives the cleaning rod 52 to insert into the extrusion cylinder 2. Finally, the first end cap 33 is sealed outside the second sealing ring 41, and the second end cap 53 on the outside of the second bushing 51 is sealed. Outside the first sealing ring 26, the liquid supply pipe 58 is connected to the external device. The liquid supply pipe 58 can input cleaning agent into the extrusion cylinder 2 through the output end located on the end face of the second bushing 51 to soak the inner wall of the extrusion cylinder 2. During the soaking process, the cleaning rod 52 is driven to rotate by the second motor 54, so that the cleaning rod 52 agitates and disperses the cleaning agent inside the extrusion cylinder 2, so that the cleaning agent is fully submerged in the inner wall of the extrusion cylinder 2, and has a moving brushing function on the inner wall of the extrusion cylinder 2 to ensure the cleaning effect of the extrusion cylinder 2.

[0088] After cleaning, the moving trolley 34 pulls the extrusion rod 32 out of the cleaning cylinder 4, and at the same time, the moving trolley 34 pulls the second bushing 51 out of the sealing sleeve 24. At this time, the cleaning agent inside the extrusion cylinder 2 can be discharged downwards at an angle. The discharged cleaning agent flows into the water tank 17 for temporary storage. After cleaning, the cleaning agent can be rinsed by injecting clean water into the cleaning cylinder 4 and the extrusion cylinder 2 to prevent cleaning agent residue. The inclined state of the extrusion cylinder 2 facilitates internal drainage and drying.

[0089] In order to achieve horizontal movement of the extrusion rod 32 while simultaneously driving the cleaning rod 52 to tilt and cooperate with the tilted extrusion cylinder 2, refer to Figure 7 , Figure 8 , Figure 9 andFigure 13 The inside of the track plate 312 is provided with a guide hole 313 along the length direction, the outside of the moving trolley 34 is fixedly provided with a linkage plate 36, the inside of the linkage plate 36 is vertically provided with a sliding hole 37; the outside of the connecting seat 55 is fixedly provided with a sliding pin 57, the sliding pin 57 is slidably arranged in the inside of the sliding hole 37 through the guide hole 313. The sliding cooperation of the obliquely arranged track plate 312 and the sliding rail 56 enables the connecting seat 55 to move obliquely along the track plate 312, and the moving of the moving trolley 34 drives the horizontal movement of the outside linkage plate 36, and the linkage plate 36 drives the horizontal movement of the inside sliding pin 57. Since the sliding pin 57 has a height difference in the process of translation, the sliding hole 37 in the inside of the linkage plate 36 cooperates with the sliding pin 57, so that the sliding pin 57 can vertically slide in the inside of the sliding hole 37 in the process of translation, thereby achieving the effect of synchronous movement of the cleaning rod 52 and the extrusion rod 32.

[0090] In order to facilitate the re-conveying of the once-extruded plastic particles into the inside of the extrusion cylinder 2, the production of color master batch by mixing with pigments, with reference to Figure 1 and Figure 14 Further comprising a material box 6 fixedly arranged outside the support seat 1, the material box 6 is located below the cooling die head 22, a push plate 61 is slidably arranged in the inside of the material box 6, the push plate 61 is fixedly arranged at the driving end of a third push rod 62, and the third push rod 62 is fixedly arranged in the inside of the material box 6; further comprising a feeding assembly 7 for feeding the plastic particles in the inside of the material box 6 to the feeding hopper 21, the feeding assembly 7 comprises a vertical conveying channel 71 fixedly arranged at one side of the inside of the material box 6 and a horizontal conveying channel 72 fixedly arranged outside the vertical conveying channel 71, the output end of the vertical conveying channel 71 is aligned with the input end of the horizontal conveying channel 72, the output end of the horizontal conveying channel 72 is located above the feeding hopper 21, and the side of the push plate 61 facing the feeding assembly 7 is arranged as an inclined surface.

[0091] When the plastic particles are once extruded, the third push rod 62 drives the push plate 61 to slide in the inside of the material box 6, so that the inclined surface of the push plate 61 is located at the side of the cooling die head 22 away from the feeding assembly 7, at this time the push plate 61 can concentrate the extruded plastic particles at the feeding end of the feeding assembly 7; after the extrusion cylinder 2 and the extrusion rod 32 are cleaned and assembled, the vertical conveying channel 71 lifts and conveys the plastic particles in the inside of the material box 6 to the inside of the horizontal conveying channel 72, and then the horizontal conveying channel 72 inputs the plastic particles into the inside of the feeding hopper 21, so as to re-mix the once-extruded plastic particles with the pigments to process color master batch.

[0093] In the specific conveying process, referring to Figure 14 , Figure 15 , Figure 16 and Figure 17 , the vertical conveying channel 71 is fixedly arranged inside the material box 6 through the top cover 73 on the outside, the vertical conveying channel 71 is provided with a feeding port 75 at the bottom, the vertical conveying channel 71 is rotatably provided with a screw rod 74 inside, the output end of the vertical conveying channel 71 is fixedly provided with a discharge pipe 76, the discharge pipe 76 is inserted into the inside of the horizontal conveying channel 72, and the vertical conveying channel 71 is fixedly provided with a cantilever 77 for mounting the horizontal conveying channel 72 on the outside; the inside of both ends of the horizontal conveying channel 72 is provided with a sealing bearing 721, the inside of the sealing bearing 721 is fixedly provided with a grid cylinder 722, one end of the grid cylinder 722 inclined downward is fixedly provided with an extension pipe 723, the other end of the grid cylinder 722 is fixedly provided with a gear ring 724, the top of the vertical conveying channel 71 is fixedly provided with a gear box 78, both output ends of the gear box 78 are linked with the screw rod 74 and the gear 79 respectively, the gear 79 is meshingly arranged on the outside of the gear ring 724, the outside of the gear box 78 is fixedly provided with a third motor 710 for driving the screw rod 74 and the gear 79 to rotate, the outside of the horizontal conveying channel 72 is fixedly provided with an air pipe 725, the other end of the air pipe 725 is fixedly provided with a fan 726, the fan 726 is fixedly arranged at the bottom of the cantilever 77, and the outside of the fan 726 is fixedly provided with an air outlet pipe 727 for mounting a filtering device.

[0094] The screw rod 74 and the gear 79 at the driving end of the gear box 78 are driven to rotate by the third motor 710 at the same time, so that the screw rod 74 lifts the plastic particles inside the material box 6 into the inside of the discharge pipe 76 and the inside of the grid cylinder 722, the grid cylinder 722 rotates under the drive of the gear 79, and the stirring and dispersing functions of the plastic particles are realized, at this time, the powder generated in the stirring process of the plastic particles in the inside of the horizontal conveying channel 72 can be sucked out through the air pipe 725 of the suction end of the fan 726, and finally the dust is filtered through the filtering device connected by the air outlet pipe 727 (such as cloth bag filtering, electrostatic adsorption filtering, etc.), so as to prevent the plastic particles from carrying too much powder when they are processed into color master batches, which affects the processing quality; at this time, the push plate 61 is driven to move close to the vertical conveying channel 71 by the third push rod 62, so that the plastic particles inside the material box 6 are pushed to the feeding port 75 at the bottom of the vertical conveying channel 71 for conveying, and at the same time, the push plate 61 is pushed to the side close to the feeding assembly 7 of the cooling die head 22, so as to temporarily store the color master batch in the other part of the material box 6.

[0095] In summary, the plastic recycling-based color master batch processing equipment disclosed in the embodiments of the present application is used by putting the plastic recycling particles after cleaning, sorting and crushing into the inside of the feeding hopper 21, mixing and extruding the plastic particles through the extrusion rod 32 inside the extrusion cylinder 2, and finally extruding and forming through the cooling die head 22 at the output end of the extrusion cylinder 2. The output end of the cooling die head 22 is a plurality of hole-shaped channels, and the extruded material is cooled into plastic strips when passing through the output end of the cooling die head 22. Then, the first motor 234 is driven to rotate the drive shaft 232 at high speed, so that the drive shaft 232 drives the cutter 233 to cut the extruded plastic strips at the output end of the cooling die head 22, and the formed plastic particles fall into the inside of the material box 6 for storage.

[0096] When the plastic particles are mixed and extruded through the extrusion rod 32 inside the extrusion cylinder 2, impurities and residues will adhere to the inner wall of the extrusion cylinder 2 and the surface of the extrusion rod 32 after a period of time. At this time, the moving trolley 34 is moved along the second guide rail 38, which drives the first shaft sleeve 31 to move along the Y-axis direction, thereby driving the extrusion rod 32 to be extracted from the inside of the extrusion cylinder 2, so as to detach the extrusion cylinder 2 and the extrusion rod 32 from each other. Then, the automatic sliding block 311 is slid along the first guide rail 18 to drive the second guide rail 38 to move, so that the second guide rail 38 drives the moving trolley 34 and the extrusion rod 32 to move and approach the cleaning cylinder 4. When the extrusion rod 32 is aligned with the cleaning cylinder 4, the moving trolley 34 drives the extrusion rod 32 to be inserted into the inside of the cleaning cylinder 4. When the moving trolley 34 drives the extrusion rod 32 to be aligned with the cleaning cylinder 4, the bottom plate 310 drives the track plate 312 to move along the X-axis direction synchronously, so that the track plate 312 drives the connecting seat 55 to move synchronously, thereby driving the cleaning rod 52 to be coaxially aligned with the extrusion cylinder 2. When the moving trolley 34 drives the extrusion rod 32 to move into the inside of the cleaning cylinder 4, the moving trolley 34 drives the cleaning rod 52 to be inserted into the inside of the extrusion cylinder 2 synchronously. Finally, the first end cover 33 is sealingly arranged outside the second sealing ring 41, and the second end cover 53 outside the second shaft sleeve 51 is sealingly arranged outside the first sealing ring 26.

[0097] At this time, the external device is connected with the liquid supply pipe 58, and the liquid supply pipe 58 can input the cleaning agent into the inside of the extrusion barrel 2 through the output end on the end face of the second shaft sleeve 51 to soak the inner wall of the extrusion barrel 2. In the soaking process, the second motor 54 drives the cleaning rod 52 to rotate, so that the cleaning rod 52 stirs and disperses the cleaning agent in the inside of the extrusion barrel 2, so that the cleaning agent is fully immersed in the inner wall of the extrusion barrel 2, and has a moving brushing function for the inner wall of the extrusion barrel 2, so as to ensure the cleaning effect of the extrusion barrel 2. At the same time, a certain amount of cleaning agent is added into the inside of the cleaning barrel 4 through the water inlet pipe 42, and the extrusion rod 32 is cleaned by the ultrasonic generator on the inner wall of the cleaning barrel 4. The extrusion rod 32 can also be placed outside the cleaning barrel 4, and the more obvious impurities on the surface of the extrusion rod 32 are cleaned by manual tools before cleaning. After cleaning is completed, the moving trolley 34 drives the extrusion rod 32 to pull out the inside of the cleaning barrel 4, and the moving trolley 34 drives the second shaft sleeve 51 to pull out the inside of the sealing sleeve 24. At this time, the cleaning agent in the inside of the extrusion barrel 2 can be inclined and discharged downward.

[0098] When the extrusion barrel 2 and the extrusion rod 32 are assembled and cleaned, the third motor 710 simultaneously drives the helical rod 74 and the gear 79 at the driving end of the gear box 78 to rotate, so that the helical rod 74 lifts the plastic particles in the material box 6 to the inside of the discharge pipe 76 and inputs them into the inside of the grid barrel 722. The grid barrel 722 rotates under the drive of the gear 79 to realize the stirring and dispersing function of the plastic particles. At this time, the powder generated by the plastic particles in the horizontal conveying channel 72 in the stirring process can be sucked out through the air pipe 725 of the suction end of the fan 726. Finally, the dust is filtered by the filtering device connected to the air outlet pipe 727 to prevent the plastic particles from carrying too much powder during the processing of the color master batch, which affects the processing quality.
