Technical Field
[0001] The invention relates to the technical field of extruders, and in particular to an extruder that is easy to assemble and disassemble. Background Art
[0002] The twin-screw extruder is developed on the basis of the single-screw extruder. It has been widely used in the molding of extruded products due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics.
[0003] Currently in the plastic film production process, the discharge port of the plastic extruder extrude the molten plastic into sheets, which are then further extruded and formed through pressure rollers.
[0004] In addition, the installation and disassembly of the extruder is complicated, and it is not convenient to disassemble the extruder. It takes a long time to disassemble when cleaning the screw. There are currently two ways to clean the extruder screw. One is to put new material into the extruder to extrude the old material to achieve the extruder cleaning effect. This method is likely to cause material waste and increase production costs. The second is to use chemical reagents for cleaning, which will leave chemical reagents and corrode the internal surface of the extruder, and the screw needs to be removed from the end of the extruder housing. The process of removing the screw requires the cooperation of multiple workers, which is labor-intensive and not easy to clean the screw. In order to avoid material waste and chemical reagents corroding the internal surface of the extruder, we propose an extruder that is easy to disassemble and assemble. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides an extruder that is easy to disassemble and assemble, comprising:
[0006] A housing, the exterior of which is provided with a fixing frame, and a bottom plate arranged at the bottom of the fixing frame;
[0007] An extrusion mechanism, which is used to extrude materials, and a support frame arranged at the end of the extrusion mechanism;
[0008] A disassembly mechanism, the disassembly mechanism having a movable structure, for disassembling the extrusion mechanism;
[0009] The outer surface of the shell is fixedly connected to the inner side of the fixing frame, the end of the fixing frame away from the shell is fixedly connected to the top of the bottom plate, the surface of the splitting mechanism is fixedly connected to the inner wall of the shell, and the side of the splitting mechanism away from the inner wall of the shell is fixedly connected to the outer surface of the extrusion mechanism, the outer surface of the extrusion mechanism is fixedly connected to the end of the support frame, and the end of the support frame away from the extrusion mechanism is fixedly connected to the top of the bottom plate;
[0010] Wherein, the extrusion mechanism comprises:
[0011] A housing, wherein two of the housings are symmetrically arranged, and the sides of the two housings close to each other are both arranged in a wave shape, and the sides of the two housings close to each other cooperate with each other, and screws are symmetrically arranged inside the housings;
[0012] A loading assembly, the loading assembly having a loading structure for loading plastic raw materials into the shell, and a connecting block disposed on the top of the shell;
[0013] A transmission assembly, the transmission assembly is used to drive the two screws inside the housing to rotate in opposite directions;
[0014] The outer surface of the shell is fixedly connected to the side of the splitting mechanism away from the inner wall of the shell, the outer surface of the feeding assembly is fixedly connected to the outer surface of the connecting block, and the side of the connecting block away from the feeding assembly is fixedly connected to the top of the transmission assembly, and the side of the transmission assembly close to the bottom plate is fixedly connected to the side of the support frame away from the bottom plate. The feeding assembly fills the plastic raw material into the shell, and the transmission assembly drives the two screws to rotate in different directions, thereby driving the plastic raw material to fill the shell, and then the plastic raw material is melted and extruded to form a film material. When the screw of the extruder needs to be cleaned, the splitting mechanism drives the two shells away from each other, so that the side of the two screws close to each other leaks out, and then rinses with high-pressure water flow to peel off the solidified plastic on the surface of the screw, and rinses from the side of the two screws close to each other. During the rinsing, the two screws are driven to rotate, and all positions of the two screws can be cleaned at the same time, and the side of the two shells close to each other is set to a mutually adaptive wave shape, so that when the two shells cooperate, they can be fully engaged, which can avoid the leakage of the melted plastic raw material when the extruder is working, thereby maintaining the normal use of the extruder.
[0015] Furthermore, a clamping block is provided at one end of the two shells away from the transmission assembly, and the outer surfaces of the two clamping blocks are fixedly connected to the ends of the two shells respectively, and the sides of the two clamping blocks close to each other are arranged in a stepped shape, a limiting block is provided at the interval between the two clamping blocks, and the outer surface of the limiting block is adapted to the sides of the two clamping blocks close to each other, and a die head is fixedly connected to the side of the limiting block away from the clamping block, and the screw drives the melted plastic raw material inside it to move forward, and then passes through the limiting block and is finally extruded from the die head to form a film material. Since the sides of the two clamping blocks close to each other are arranged in a stepped shape, and the limiting block and the clamping block are adapted to each other, the clamping connection between the clamping block and the limiting block is more firm, and the sealing effect between the two is better, so that the melted plastic raw material is prevented from leaking from the die head, and when the two shells are away from each other, the limiting block can be taken out, and the die head is also taken out accordingly, and the removed die head is easier to be cleaned, thereby avoiding the solidified plastic raw material inside the die head and avoiding affecting the molding of the material.
[0016] Furthermore, an L-groove is provided inside the die head, and the interval between the L-groove and the notch horizontal to the central axis of the screw gradually decreases. A corrugated groove is provided on the side of the L-groove close to the limit block. The melted plastic raw material first contacts the limit block, and then the liquid level gradually rises and finally enters the corrugated groove. The corrugated groove can make the raw material evenly distributed in the depression of the corrugated groove, so that the plastic raw material can evenly enter the L-groove. The notch interval of the L-groove gradually decreases, so that the farthest end of the notch of the L-groove can be completely filled with plastic. The setting of the corrugated groove and the L-groove enables the raw material to completely fill the L-groove and be evenly extruded from various parts of the L-groove, so that the raw material just extruded is smoother, and no bubbles or gaps are generated, and its end face is also smoother.
[0017] Furthermore, the transmission assembly includes a casing, the top of the casing is fixedly connected to the connecting block, the inner wall of the casing is fixedly connected to a transmission motor, a driving shaft is arranged on a side of the transmission motor close to the casing, the driving shaft is fixedly connected to an output end of the transmission motor, the outer surface of the driving shaft is fixedly connected to a driving gear, the outer surface of the driving gear is meshingly connected to a driven gear, the inner wall of the driven gear is fixedly connected to a driven shaft, and an end of the driven shaft away from the casing is rotatably connected to the inner wall of the casing, the driving shaft and the driven shaft close to the casing both penetrate the casing and extend to the inside of the casing and are respectively fixedly connected to two screws, and the outer surfaces of the driving shaft and the driven shaft are rotatably connected to the inner wall of the casing, the transmission motor is started, and the output end of the transmission motor drives the driving shaft to rotate, drives the driving gear to rotate, thereby drives the driven gear meshing with the driving gear to rotate, drives the driven shaft to rotate, and finally drives the two screws to rotate in opposite directions, so as to stir and extrude the plastic raw materials inside the casing.
[0018] Furthermore, a groove is provided on one side of the two shells close to each other, and the two grooves are arranged in the compression section of the screw. The inner walls of the two grooves are fixedly connected with heaters, and the heaters heat and melt the plastic raw materials in the compression section of the screw. At the same time, when the shells move away from each other, the two heaters are driven to move, so that the entire screw is completely exposed.
[0019] Furthermore, the feeding assembly includes a feeding barrel, the outer surface of which is fixedly connected to a side of the connecting block away from the casing, the feeding barrel extends to the interior of the shell, and is configured to be conical, a barrel cover is fixedly connected to the side of the feeding barrel away from the shell, a feeding port is provided on the outer surface of the barrel cover, and plastic raw materials are put into the feeding port, the plastic raw materials enter the inside of the feeding barrel, and are finally filled into the shell. Since the feeding barrel is configured to be conical, more raw materials can be filled during feeding.
[0020] Furthermore, a feeding motor is fixedly connected to a side of the barrel cover away from the loading barrel, and an output end of the feeding motor is fixedly connected to a stirring shaft, and the stirring shaft extends to the bottom of the loading barrel, and a bent rod is fixedly connected to the outer surface of the stirring shaft, and the number of the bent rods is set, and the ends of the bent rods away from the stirring shaft are fixedly connected with a lifting block, and a screw sheet is fixedly connected to the outer surface of the stirring shaft, and the screw sheet is arranged on a side of the stirring shaft close to the shell body. When loading, the feeding motor is started, and the output end of the feeding motor drives the stirring shaft to rotate, and the stirring shaft drives the bent rod to rotate, and the bent rod drives the lifting block to rotate. At the same time, the stirring shaft drives the screw sheet to rotate, and the screw sheet rotates, driving the plastic raw material on the surface of the screw sheet to move, thereby filling the plastic raw material into the shell body. Loading through the screw sheet can avoid direct loading and causing the loading barrel to be blocked. When the bent rod drives the lifting block to rotate, the raw material inside the loading barrel can be lifted, so that gaps are generated between the raw materials, avoiding the raw materials from being pressed inside the loading barrel, so that the raw materials can be more easily loaded from the screw sheet.
[0021] Furthermore, the splitting mechanism includes a telescopic rod, two of which are symmetrically arranged inside the shell, and the sides of the two telescopic rods that are away from each other are fixedly connected to the inner wall of the shell, and the sides of the two telescopic rods that are close to each other are respectively fixedly connected to the outer surface of the shell, and frames are symmetrically arranged on both sides of the two telescopic rods, and the frames are fixedly connected to the inner wall of the shell, and the inner wall of the frame is provided with an H-groove, and a slide is slidably connected to the inner wall of the H-groove, and the side of the slide away from the frame is fixedly connected to the outer surface of the shell. During disassembly, the telescopic rod contracts, driving the two shells away from each other, so that the two screws are exposed, and when the shell moves, the slide is driven to move, and the slide slides inside the frame. Since the frame is provided with an H-groove, the H-groove can make the slide more stable when moving, thereby avoiding shaking when the shell moves, and then avoiding gaps when the two shells cooperate, ensuring that the raw materials will not leak.
[0022] Furthermore, cover plates are symmetrically arranged on both sides of the shell, and the sides of the two cover plates close to each other are fixedly connected to the outer surface of the shell, and the inner wall of the cover plate is fixedly connected to a spring plate, and the spring plate is arranged in a wavy shape, and the end of the spring plate away from the inner wall of the cover plate is fixedly connected to the outer surface of the shell. When the two shells are away from each other, the shell slides on the inner wall of the cover plate, and the spring plate is compressed and folded, thereby preventing external impurities from entering the interior of the shell from the cover plate, thereby maintaining the cleanliness of the screw after cleaning.
[0023] Furthermore, a limiting groove is provided on one side of the shell away from the bottom plate, an elliptical ring is slidably connected inside the limiting groove, and the long axis of the elliptical ring is parallel to the central axis of the screw, the inner wall of the elliptical ring is rotatably connected to the nozzle through a rotating rod, and the inner wall of the nozzle is provided with a thread, and arc plates are symmetrically arranged in an inverted eight-shaped shape on one side of the shell away from the nozzle, and the sides of the two arc plates away from each other are fixedly connected to the inner wall of the shell, and a plurality of filter grooves are provided on the surfaces of the two arc plates. When cleaning, a water pipe is connected through the thread of the nozzle, and the water pipe flows from the nozzle The head sprays out high-pressure water flow to flush the screw. The nozzle moves, driving the elliptical ring to slide inside the limiting groove, thereby flushing most of the screw. The nozzle is rotated, and the nozzle rotates to further increase the flushing range of the screw, thereby achieving the effect of flushing the entire screw. The solidified plastic under flushing leaves the shell from the gap between the two arc plates to avoid the solidified plastic being splashed everywhere by the water flow, thereby achieving the effect of plastic recovery. At the same time, the water is filtered out through the opened filter tank to avoid the solidified plastic from adhering to the inverted arc plate due to more water.
[0024] The present invention has the beneficial effects:
[0025] The present invention provides a disassembly mechanism. When cleaning the screw of the extruder, the disassembly mechanism drives the two shells to move away from each other, so that the side where the two screws are close to each other leaks out. Then, the high-pressure water flow is used for flushing to peel off the solidified plastic on the surface of the screw, and the flushing is performed from the side where the two screws are close to each other. During the flushing, the two screws are driven to rotate, and all positions of the two screws can be cleaned at the same time. The side where the two shells are close to each other is set to a mutually compatible wave shape, so that the two shells can be fully engaged when matched, and the melted plastic raw material can be prevented from leaking when the extruder is working, thereby maintaining the normal use of the extruder.
[0026] The present invention sets a die head, and when the two shells are away from each other, the limit block can be taken out, and the die head is also taken out. The removed die head is easier to be cleaned, thereby avoiding the solidified plastic raw material inside the die head and affecting the molding of the material. The melted plastic raw material first contacts the limit block, and then the liquid level gradually rises and finally enters the corrugated groove. The corrugated groove can make the raw material evenly distributed in the depression of the corrugated groove, so that the plastic raw material evenly enters the L groove. The notch spacing of the L groove gradually decreases, so that the farthest end of the notch of the L groove can be completely filled with plastic. The setting of the corrugated groove and the L groove enables the raw material to completely fill the L groove and be evenly extruded from various parts of the L groove, so that the raw material just extruded is smoother, and no bubbles or gaps are generated, and its end face is also smoother.
[0027] The present invention provides a feeding component. Since the feeding barrel is configured in a conical shape, more raw materials can be filled during feeding. Feeding through the screw blade can avoid clogging of the feeding barrel due to direct feeding. When the bent rod drives the lifting block to rotate, the raw materials inside the feeding barrel can be lifted, so that gaps are generated between the raw materials, avoiding the raw materials from being compressed inside the feeding barrel, thereby making it easier to feed the raw materials from the screw blade.
[0028] The present invention provides a nozzle, and during cleaning, the chemical reagent is sprayed onto the screw of the extruder. After sufficient reaction, the water pipe is connected to the thread of the nozzle, and the water pipe sprays a high-pressure water flow from the nozzle. The high-pressure water flow washes the solidified plastic and the chemical reagent on the surface of the screw. The nozzle moves, driving the elliptical ring to slide inside the limiting groove, thereby washing most of the screw and removing the chemical reagent in time, thereby avoiding the chemical reagent from damaging the screw of the extruder. The nozzle is rotated, and the nozzle rotates, further increasing the washing range of the screw by the nozzle, thereby achieving the effect of washing the entire screw. The washed solidified plastic leaves the shell from the gap between the two arc plates, avoiding the solidified plastic from being washed by the water flow and splashing everywhere, thereby achieving the effect of recycling the plastic.

[0042] A disassembly mechanism 4, wherein the disassembly mechanism 4 has a movable structure and is used to disassemble the extrusion mechanism 3;
[0043] The outer surface of the shell 5 is fixedly connected to the inner side of the fixing frame 2, the end of the fixing frame 2 away from the shell 5 is fixedly connected to the top of the bottom plate 1, the surface of the splitting mechanism 4 is fixedly connected to the inner wall of the shell 5, and the side of the splitting mechanism 4 away from the inner wall of the shell 5 is fixedly connected to the outer surface of the extrusion mechanism 3, the outer surface of the extrusion mechanism 3 is fixedly connected to the end of the support frame 6, and the end of the support frame 6 away from the extrusion mechanism 3 is fixedly connected to the top of the bottom plate 1;
[0044] Wherein, the extrusion mechanism 3 comprises:
[0045] A housing 31, wherein two housings 31 are symmetrically arranged, and the sides of the two housings 31 close to each other are both arranged in a wave shape, and the sides of the two housings 31 close to each other cooperate with each other, and a screw 39 symmetrically arranged inside the housing 31;

[0047] A transmission assembly 32, the transmission assembly 32 is used to drive two screws 39 inside the housing 31 to rotate in opposite directions;
[0048] The outer surface of the shell 31 is fixedly connected to the side of the splitting mechanism 4 away from the inner wall of the shell 5, the outer surface of the feeding component 33 is fixedly connected to the outer surface of the connecting block 34, and the side of the connecting block 34 away from the feeding component 33 is fixedly connected to the top of the transmission component 32, and the side of the transmission component 32 close to the bottom plate 1 is fixedly connected to the side of the support frame 6 away from the bottom plate 1. The feeding component 33 fills the plastic raw material into the shell 31, and the transmission component 32 drives the two screws 39 to rotate in different directions, thereby driving the plastic raw material to fill the shell 31. Then, the plastic raw material is melted and extruded to form a film material. The screw 39 of the extruder needs to be rotated. When cleaning, the splitting mechanism 4 drives the two shells 31 away from each other, so that the side where the two screws 39 are close to each other leaks out, and then flushes with high-pressure water to peel off the solidified plastic on the surface of the screw 39, and flushes from the side where the two screws 39 are close to each other. During flushing, the two screws 39 are driven to rotate, and all positions of the two screws 39 can be cleaned at the same time. The side where the two shells 31 are close to each other is set to a mutually compatible wave shape, so that the two shells 31 can be fully engaged when matched, which can avoid the leakage of melted plastic raw materials when the extruder is working, thereby maintaining the normal use of the extruder.

The screw 39 drives the melted plastic material inside it to move forward, and then passes through the limiting block 36 and finally exits from the die head. 37 is extruded to form a film material. Since the side where the two clamping blocks 35 are close to each other is set in a stepped shape, and the limiting block 36 is adapted to the clamping block 35, the clamping connection between the clamping block 35 and the limiting block 36 is more firm, so that the sealing effect between the two is better, and the melted plastic material is prevented from leaking from the die head 37. When the two shells 31 are away from each other, the limiting block 36 can be taken out, and the die head 37 is also taken out.

The corrugated groove 310 can make the raw material evenly distributed in the depression of the corrugated groove 310, so that the plastic raw material evenly enters the L-groove 311. The notch interval of the L-groove 311 gradually decreases, so that the farthest end of the notch of the L-groove 311 can be completely filled with plastic. The setting of the corrugated groove 310 and the L-groove 311 enables the raw material to completely fill the L-groove 311 and be evenly extruded from various parts of the L-groove 311, so that the raw material just extruded is smoother, and no bubbles or gaps are generated, and its end face is also smoother.

When disassembling, the telescopic rod 41 contracts, driving the two shells 31 away from each other, so that the two screws 39 are exposed. When the shell 31 moves, the slide plate 44 is driven to move, and the slide plate 44 slides inside the frame 42. Since the H-groove 43 is provided inside the frame 42, the H-groove 43 can make the slide plate 44 more stable when moving, thereby avoiding shaking when the shell 31 moves, and then avoiding a gap when the two shells 31 cooperate, ensuring that the raw materials will not leak.
[0056] Cover plates 45 are symmetrically arranged on both sides of the outer shell 5. The sides of the two cover plates 45 that are close to each other are fixedly connected to the outer surface of the outer shell 5. The inner wall of the cover plate 45 is fixedly connected to a spring plate 46, and the spring plate 46 is arranged in a wavy shape. The end of the spring plate 46 away from the inner wall of the cover plate 45 is fixedly connected to the outer surface of the shell 31. When the two shells 31 are away from each other, the shell 31 slides on the inner wall of the cover plate 45, and compresses and folds the spring plate 46, thereby preventing external impurities from entering the interior of the shell 31 from the cover plate 45, thereby maintaining the cleanliness of the screw 39 after cleaning.
[0057] A limiting groove 47 is provided on one side of the housing 5 away from the bottom plate 1, and an elliptical ring 48 is slidably connected inside the limiting groove 47, and the long axis of the elliptical ring 48 is parallel to the central axis of the screw 39. The inner wall of the elliptical ring 48 is rotatably connected to a nozzle 49 through a rotating rod, and the inner wall of the nozzle 49 is provided with a thread. An arc plate 410 is symmetrically arranged in an inverted eight-shaped shape on one side of the housing 5 away from the nozzle 49, and the sides of the two arc plates 410 away from each other are fixedly connected to the inner wall of the housing 5, and a plurality of filter grooves 411 are provided on the surfaces of the two arc plates 410. When cleaning, the chemical reagent is sprayed onto the screw 39 of the extruder. After sufficient reaction, the water pipe is connected through the thread of the nozzle 49, and the water pipe sprays a high-pressure water flow from the nozzle 49, and the high-pressure water flow acts on the screw. The solidified plastic and chemical reagents on the surface of 39 are rinsed, the nozzle 49 moves, driving the elliptical ring 48 to slide inside the limiting groove 47, thereby rinsing most of the screw 39 and removing the chemical reagents in time, thereby avoiding the chemical reagents from damaging the extruder screw 39, rotating the nozzle 49, and further increasing the rinsing range of the nozzle 49 on the screw 39, thereby achieving the effect of rinsing the entire screw 39, and the solidified plastic under rinsing leaves the housing 5 from the gap between the two arc plates 410, avoiding the solidified plastic from being splashed around by the water flow, thereby achieving the effect of recycling the plastic, and at the same time, through the filter groove 411, the water is filtered away to avoid the solidified plastic from adhering to the inverted arc plate 410 due to more water.
[0058] When in use, the transmission motor 322 is started, and the output end of the transmission motor 322 drives the active shaft 323 to rotate, drives the active gear 324 to rotate, thereby drives the driven gear 325 meshing with the active gear 324 to rotate, drives the driven shaft 326 to rotate, and finally drives the two screws 39 to rotate in different directions, and then the material is loaded, the plastic raw material is put into the loading port 333, and the plastic raw material enters the loading barrel 331, and the loading motor 334 is started. The output end of the loading motor 334 drives the stirring shaft 335 to rotate, the stirring shaft 335 drives the bending rod 336 to rotate, and the bending rod 336 drives the lifting block 337 to rotate, and at the same time the stirring shaft 335 drives the screw piece 338 to rotate, and the screw piece 338 rotates, driving the screw piece 338 to rotate. The plastic raw material on the surface moves, thereby filling the plastic raw material into the shell 31, and the screw 39 drives the melted plastic raw material inside it to move forward. After the raw material reaches the compression section of the screw 39, the heater 312 heats and melts the plastic raw material in the compression section of the screw 39. The melted plastic raw material continues to move forward with the screw 39. The melted plastic raw material first contacts the limit block 36, and then the liquid level gradually rises, and finally enters the corrugated groove 310. The corrugated groove 310 can make the raw material evenly distributed in the concave part of the corrugated groove 310, so that the plastic raw material evenly enters the L groove 311. The notch interval of the L groove 311 gradually decreases, so that the farthest end of the notch of the L groove 311 can be completely filled with plastic, and finally extruded evenly from the die head 37;
[0059] During cleaning, the telescopic rod 41 contracts, driving the two shells 31 away from each other, driving the two heaters 312 to move, so that the entire screw 39 is completely exposed. When the shell 31 moves, it drives the slide plate 44 to move. The slide plate 44 slides inside the frame 42 to spray the chemical reagent onto the screw 39 of the extruder. After sufficient reaction, the water pipe is connected to the thread of the nozzle 49, and the water pipe sprays a high-pressure water flow from the nozzle 49. The high-pressure water flow flushes the solidified plastic and chemical reagent on the surface of the screw 39. The nozzle 49 moves, driving the elliptical ring 48 to slide inside the limiting groove 47, thereby flushing most of the screw 39. The nozzle 49 is rotated, and the nozzle 49 rotates to further increase the flushing range of the nozzle 49 on the screw 39, thereby achieving the effect of flushing the entire screw 39. The flushed solidified plastic leaves the housing 5 from the gap between the two arc plates 410.
