Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, specifically a pelletizing machine for engineering plastic production. Background Technology

[0002] With the rapid development of the engineering plastics industry, the application of high-performance engineering plastics such as polyamide (PA), polycarbonate (PC) and polybutylene terephthalate (PBT) is becoming increasingly widespread. In the production process of these materials, the granulation process is the core link connecting hot melt synthesis and final molding. At present, the mainstream granulation method is the extrusion strip pelletizing method, that is, the raw material is hot melt extruded into continuous strips, and after cooling and solidification, it is crushed into pellets by a pelletizer. When the molten strips are first passed through the extruder, they are usually arranged side by side and need to be transferred to a cooling device (cooling tank) by a transfer roller to cool them down before pelletizing. It is difficult to transfer them through mechanical equipment. Therefore, operators usually guide and transfer the disordered and drooping molten strips simultaneously by holding special clamps or wearing high-temperature gloves. As a result, multiple sets of parallel strips will gather together and stick together in the hot melt state. When they are cut after cooling, they will be cut into strips that do not meet the requirements. Moreover, due to the gathering operation, the overall angle of the strips will be offset. After being guided, some strips will be tilted, resulting in the cut dimensions not meeting the requirements. Therefore, the present invention provides a pelletizing machine for engineering plastics production to solve the above-mentioned problems. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. When the device of the present invention is used, the descent of the movable plate, in conjunction with the synchronous locking of the clamping plate, applies a continuous, uniform and vertically downward "active traction force" to the initially extruded molten strip. This traction can effectively prevent the strip from bending and swaying due to gravity falling alone. During the descent, the strip is simultaneously cooled by the cooling component under tension, so that it is "linearly locked" in the stage where its physical form is most unstable. This ensures that the strip exhibits extremely high verticality and straightness after solidification, effectively preventing the strip from gathering and causing some strips to tilt, resulting in the cut dimensions not meeting the requirements. 2. When the device of the present invention is used, the segmented adjustment mode of the movable plate enables it to perform reciprocating operation after the initial traction operation is completed, so that the top area of ​​the pull bar can be effectively cooled by the cooling component, and only the bottom area of ​​the pull bar is pulled, adjusted and cut, thereby effectively reducing the impact on the uncured pull bar. 3. When the device of the present invention is used, the movable plate can drive the driven plate to move and adjust after the initial operation is completed. During the upward process, the movable plate can reduce the pressure at the outlet end of the cooling chamber through the driven plate and the baffle, thereby gradually increasing the pressure of the discharged gas. This will gradually strengthen the rapid cooling treatment of the pull bar, enhance its tensile strength, enable it to withstand higher frequency traction without deformation, and make it easier to be clamped and cut in subsequent processes.

[0026] 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 some embodiments of the present invention, and not all embodiments. 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.

[0027] Please see Figures 1-12In this embodiment of the invention, a granulator for engineering plastics production includes a support frame 1. A raw material conveying component 2 is mounted on the support frame 1. The raw material conveying component 2 includes an inlet, a hot-melt processing component, and a conveying component. The hot-melt processing component is used to hot-melt plastic raw materials, and its hot-melt processing method is prior art and will not be described in detail. The conveying component is installed at the outlet of the hot-melt processing component and is used to convey the hot-melt raw materials. Its conveying method includes, but is not limited to, spiral extrusion conveying, which is prior art and will not be described in detail. The inlet is installed at the top of the hot-melt processing component. An extrusion component 3 is fixedly installed at the output end of the raw material conveying component 2. The extrusion component 3 and the output end of the hot-melt processing component are connected to each other. The extrusion component 3 also conveys the raw materials from the hot-melt processing component through spiral extrusion conveying.

[0028] A working cylinder 5 is installed at the bottom of the extrusion component 3. A cooling component is installed on the side wall of the working cylinder 5. An adjustment box 6 is installed on the outer wall of the working cylinder 5. An adjustment component is installed on the adjustment box 6. A movable plate 12 is movably installed inside the working cylinder 5. A pull strip plate 13 is fixedly installed at the top of the movable plate 12. Pull strip openings are spaced apart on the pull strip plate 13. Clamping conditions are installed on the movable plate 12 corresponding to the pull strip openings. A cutting component is also installed on the movable plate 12. A circuit connection switch 19 is installed at the power connection end of the cutting component. The circuit connection switch 19 is a normally closed contact switch (or limit switch) connected in series in the power supply circuit of the processing drive motor 18. A switch control component 20 is installed on the 19. The switch control component 20 is a sliding push rod structure. The switch control component 20 is connected to the clamping condition. The clamping condition can clamp the pull strip in the pull strip opening. When the clamping operation is performed, the switch control component 20 will descend on the circuit connection switch 19, physically pressing the contact of the circuit connection switch 19, causing the control switch of the circuit connection switch 19 to open (i.e., the closed state). At this time, the cutting component does not cut the pull strip. When the clamping operation is released, the switch control component 20 will rise on the circuit connection switch 19, causing the control switch of the circuit connection switch 19 to open. At this time, the cutting component will cut the pull strip.

[0029] A slider 21 is installed on the side wall of the movable plate 12. A locking hole 22 is provided on the slider 21. A telescopic control device 4 is fixedly installed on the top of the working cylinder 5. The telescopic control device 4 is a linear drive device known in the art. It is preferably any one of an electric cylinder, hydraulic cylinder or pneumatic cylinder. Its output end is driven to perform telescopic reciprocating motion by an external control system. A lifting adjustment component is installed on the output end of the telescopic control device 4. The lifting adjustment component is connected to the slider 21 by the locking hole 22. The inner wall of the working cylinder 5 is provided with a main adjustment groove 9, and the inner side of the adjustment box 6 is provided with a through groove 34 corresponding to the position of the working cylinder 5. The through groove 34 passes through the adjustment box 6 and the side wall of the working cylinder 5 and communicates with the inside of the working cylinder 5. The main adjustment groove 9 is located above the through groove 34. The lifting adjustment component is located in the main adjustment groove 9, and the control end of the working adjustment component is located in the through groove 34. The bottom of the slider 21 is equipped with an adsorption component, which includes but is not limited to an adsorption magnet. The top of the slider 21 and the lifting adjustment component are snapped together, and the bottom of the slider 21 and the working adjustment component are adsorbed together. When the slider 21 is connected to the working adjustment component, the slider 21 and the lifting adjustment component are disconnected. The lifting adjustment component includes a trigger adjustment component. A moving groove 44 is provided on the inner wall of the working cylinder 5 corresponding to the position of the trigger adjustment component. Triggers are installed at the bottom of both the trigger adjustment component and the moving groove 44. A trigger plate 23 is installed on the side wall of the movable plate 12 corresponding to the position of the moving groove 44. Touch modules are installed at the top and bottom of the trigger plate 23. The touch module is any one of commercially available limit switches, micro switches, or magnetic induction proximity sensors. It is used to detect physical position and output electrical signals. The output end of the touch module is electrically connected to the control end of the clamping condition (i.e., the electric telescopic component 16) through a wire. When the touch module at the bottom of the trigger plate 23 contacts the trigger (i.e., the stop or induction magnetic block) at the bottom of the moving groove 44 and generates a trigger signal, the electric telescopic component 16 receives the signal and drives the lifting plate 15 to reset, so that the clamping condition no longer clamps the pull bar. When the touch module at the top of the trigger plate 23 contacts the trigger on the trigger adjustment component, the clamping condition clamps the pull bar again.

[0030] The clamping condition includes an adjustment groove 14, which is opened at the top of the movable plate 12 and is connected to the pull bar opening on the pull bar plate 13. An electric telescopic component 16 is installed at the top of the movable plate 12. The control end of the electric telescopic component 16 is connected to the output end of the touch module. A control board 17 is fixedly installed on the output end of the electric telescopic component 16. A lifting plate 15 is installed at the top of the adjustment groove 14. The lifting plate 15 and the control board 17 are fixedly connected to each other. The control board 17 and the switch control component 20 are fixedly connected to each other. A clamping plate 31 is installed on the inner side of the adjustment groove 14 corresponding to the pull bar opening. The clamping plate 31 is an arc-shaped plate that can be elastically deformed. The top of the clamping plate 31 is fixedly connected to the bottom of the lifting plate 15. The bottom of the clamping plate 31 is fixedly connected to the bottom of the inner side of the adjustment groove 14. The clamping plate 31 protrudes towards the pull bar opening. The control plate 17 is lowered by the electric telescopic component 16, which causes the lifting plate 15 to move down in the adjustment groove 14, thereby squeezing the clamping plate 31 and causing the protruding end of the clamping plate 31 to move into the pull bar, thus clamping the pull bar.

[0031] The cutting component includes a processing drive motor 18, which is mounted on a movable plate 12. A drive plate 25 and a cutter 26 are mounted on the bottom of the movable plate 12. The drive plate 25 and the cutter 26 are connected to each other via a connecting rod, and the gap between the cutter 26 and the drive plate 25 is adapted to the outer diameter of the pull strip opening. A clamping plate 27 is fixedly installed on the bottom of the movable plate 12 corresponding to the position of the connecting rod of the drive plate 25 and the cutter 26. The clamping plate 27 limits and fixes the drive plate 25 and the cutter 26. A control slot 28 is provided on the wall corresponding to the position of the machining drive motor 18. The control slot 28 is a strip-shaped arc slot. A control shaft plate 29 is installed in the control slot 28. The control shaft plate 29 is a circular block. The outer diameter of the control shaft plate 29 is adapted to the inner diameter of the control slot 28. The control shaft plate 29 and the output end of the machining drive motor 18 are connected to each other. The connection point between the control shaft plate 29 and the machining drive motor 18 is offset from the axis of the control shaft plate 29. The input end of the machining drive motor 18 is connected to the circuit connection switch 19. The machining drive motor 18 starts and drives the control shaft plate 29 to rotate in the control groove 28. The axis of the control shaft plate 29 is offset from the axis of the control groove 28 at the connection between the control shaft plate 29 and the machining drive motor 18. As the control shaft plate 29 rotates, it can drive the drive plate 25 to reciprocate on the clamping plate 27, which in turn drives the cutter 26 to cut the strip at the strip opening.

[0032] The top of the movable plate 12 is provided with a through groove 30 at both ends of the adjustment groove 14. The through groove 30 passes through the movable plate 12 and the adjustment groove 14 and communicates with each other. The bottom of the lifting plate 15 is fixedly installed with a reset plate 32 at the position corresponding to the through groove 30. The bottom end of the reset plate 32 is arc-shaped near the drive plate 25. The side wall of the drive plate 25 is provided with a clearance groove 33 at the position corresponding to the through groove 30. The clearance groove 33 is an inclined groove. When the lifting plate 15 is descending, the control switch 20 of the control board 17 adjusts the circuit connection switch 19, causing the processing drive motor 18 to stop working. The reset plate 32 on the lifting plate 15 will move down in the through groove 30, thereby squeezing the relief groove 33 on the drive plate 25. Since the motor can rotate by external force after it stops, when the reset plate 32 squeezes the relief groove 33, it will drive the drive plate 25 to move closer to the cutter 26, thereby driving the cutter 26 to move accordingly, so that the cutter 26 no longer blocks the position of the strip opening.

[0033] The lifting adjustment component includes a telescopic rod 10, which is connected to the output end of the telescopic control device 4. A return spring 42 is fixedly installed at the bottom of the telescopic rod 10. A main adjustment plate 11 is fixedly installed at the end of the return spring 42 away from the telescopic rod 10. The interior of the main adjustment plate 11 is hollow. An adjustment rod 45 is fixedly installed at the middle of the bottom of the telescopic rod 10. The adjustment rod 45 slides through the main adjustment plate 11 and extends into the main adjustment plate 11. A locking rod 46 is fixedly installed at the bottom of the main adjustment plate 11 corresponding to the position of the adjustment rod 45. The interior of the locking rod 46 is... Hollow in shape, the hollow area inside the locking rod 46 is connected to the interior of the main adjusting plate 11. Locking plates 51 are installed on both sides inside the locking rod 46. The end of the locking plate 51 away from the inner side of the locking rod 46 slides through the locking rod 46 and extends to the outside of the locking rod 46. A lock slot is opened inside the lock hole 22 corresponding to the position of the locking plate 51. A secondary adjusting plate 52 is movably installed on the end of the locking plate 51 near the adjusting rod 45. The end of the secondary adjusting plate 52 away from the locking plate 51 is movably connected to the adjusting rod 45. The two ends of the secondary adjusting plate 52 can rotate on the locking plate 51 and the adjusting rod 45 respectively. When the telescopic rod 10 moves the main adjusting plate 11 to the bottom of the main adjusting groove 9, the telescopic rod 10 will continue to descend. The main adjusting plate 11 is restricted by the bottom of the main adjusting groove 9 and cannot move. However, the adjusting rod 45 will continue to descend within the main adjusting plate 11, causing the adjusting rod 45 to drive the secondary adjusting plate 52 to adjust. This causes the secondary adjusting plate 52 to pull the locking plate 51 into the locking rod 46, separating the locking plate 51 from the locking slot in the lock hole 22. At this time, the lifting adjustment component and the movable plate 12 are disconnected.

[0034] The adjustment mechanism includes an adjustment drive motor 7, which is fixedly installed on the side wall of the adjustment box 6. A movable rod 35 is installed inside the adjustment box 6. A rack ring 37 is fixedly installed at intervals on the side wall of the movable rod 35. A drive gear 41 is fixedly installed at the output end of the adjustment drive motor 7. The drive gear 41 is located inside the adjustment box 6. Driven gears 39 are meshed on both sides of the drive gear 41. Drive gears 40 are installed on both sides of the movable rod 35 corresponding to the rack ring 37. The drive gears 40 and the driven gears 39 are fixedly connected to each other. The drive gear 40 has only one-quarter turn of teeth. The gap between two adjacent rack rings 37 is matched with the gap between the teeth of the drive gear 40. A support plate 38 is fixedly installed at the bottom of the movable rod 35. The support plate 38 extends into the working cylinder 5 through the through groove 34. A retaining ring 36 is fixedly installed on the inside of the adjustment box 6 corresponding to the position of the movable rod 35. The retaining ring 36 is used to lock and limit the movable rod 35. The rotation of the driving gear 41 drives the two driven gears 39 to rotate in different directions, causing the two sets of driving gears 40 to rotate accordingly. One set of driving gears 40 meshes with the rack ring 37, which drives the movable rod 35 to move upward. When the teeth of this set of driving gears 40 disengage from the rack ring 37, the teeth of the other set of driving gears 40 mesh with the rack ring 37, which in turn drives the movable rod 35 to move downward, thus enabling the movable rod 35 to reciprocate up and down within the retaining ring 36.

[0035] When the top of the pallet 38 contacts the bottom of the slider 21, the lifting adjustment component and the slider 21 are disconnected. The suction component at the bottom of the slider 21 will adhere to the top of the pallet 38. Under the reciprocating lifting adjustment operation of the movable rod 35, the movable plate 12 will reciprocate to the bottom of the inner side of the working cylinder 5. When the descent operation is performed, the top touch module of the trigger plate 23 on the movable plate 12 will contact the trigger component on the trigger adjustment component before the descent. At this time, the clamping condition on the movable plate 12 will clamp the pull bar, which can pull the pull bar to move vertically downward until it contacts the bottom touch module of the trigger plate 23 on the movable plate 12 and the trigger component at the bottom of the moving groove 44. At this time, the clamping condition on the movable plate 12 will disengage the clamping of the pull bar, and the corresponding cutting component will be activated. During the ascent operation, the pull bar can be cut.

[0036] The trigger adjustment component includes a movable touch control 43, which is disposed within the main adjustment plate 11. Both ends of the movable touch control 43 slide through the top and bottom of the main adjustment plate 11, respectively. The trigger element is installed at the bottom of the movable touch control 43, and the position of the movable touch control 43 corresponds to the position of the trigger plate 23. A main pressure plate 47 is fixedly installed on the top of the adjustment rod 45 near the movable touch control 43. A pressure receiving plate 48 is installed on the inner side of the main adjustment plate 11 near the end of the adjustment rod 45. The end of the pressure receiving plate 48 near the main pressure plate 47 is arc-shaped. A pressure adjusting plate is fixedly installed on the side of the movable touch control 43 near the pressure receiving plate 48. 49. The two sides of the pressure regulating plate 49 are arc-shaped. Limiting strips 53 are fixedly installed on the inner side walls of the main regulating plate 11 at the positions above and below the pressure regulating plate 49, and the side of the limiting strip 53 near the pressure regulating plate 49 is arc-shaped. Pressure transmitting bladders 50 are installed on the top of the pressure receiving plate 48 and the bottom of the pressure regulating plate 49. The two sets of pressure transmitting bladders 50 are interconnected. The pressure transmitting bladders 50 are filled with pressure transmitting materials, including but not limited to water and air. The pressure transmitting bladders 50 are connected to the pressure receiving plate 48 and the pressure regulating plate 49 respectively. When the adjusting rod 45 descends, the main pressure plate 47 will squeeze the top of the pressure receiving plate 48 until it passes over the pressure receiving plate. 48 and move to the position below the pressure plate 48. At this time, the active touch control 43 does not move because the pressure regulating plate 49 is restricted by two sets of limit bars 53, so that the trigger on the active touch control 43 can perform normal triggering operation. When the telescopic rod 10 rises, the telescopic rod 10 will drive the main pressure plate 47 to rise within the main adjusting plate 11, which will then drive the pressure plate 48 to squeeze the pressure transmission bladder 50, so that the pressure transmission bladder 50 is transmitted to the inner side, transmitting the pressure to the position below the pressure regulating plate 49, so that the pressure regulating plate 49 is pressed upward and moves past the upper set of limit bars 53 and moves to the upper position. At this time, the active touch control 4 3 will move upward, causing the trigger element to retract into the main adjustment plate 11, thus preventing it from triggering the touch module on the trigger plate 23. This allows the touch module on the trigger plate 23 to receive the trigger command from the trigger element on the moving slot 44, maintaining the clamping condition closed and the cutting element open, enabling it to perform effective finishing cutting operations. This continues until the main adjustment plate 11 moves to a position above the working cylinder 5 and contacts the top of the working cylinder 5, causing the top of the movable touch control 43 to be pressed and retract into the main adjustment plate 11. At this point, the trigger element on the movable touch control 43 will contact the touch module on the trigger plate 23, thereby opening the clamping condition and closing the cutting element.

[0037] The cooling assembly includes a cooling box 8, which is fixedly installed on the side wall of the working cylinder 5. The cooling chamber inside the cooling box 8 penetrates the side wall of the working cylinder 5 and is interconnected with it. A base block 56 is fixedly installed on the bottom inner side of the cooling box 8, and a driven plate 54 is installed on the top of the base block 56. The driven plate 54 is movably installed inside the cooling box 8 and can be adjusted in height within the cooling box 8. A storage slot 57 is provided on the inner side of the driven plate 54 corresponding to its position. A foldable and adjustable baffle 58 is installed, with the top of the baffle 58 and the bottom of the driven plate 54 fixedly connected to each other. An adsorption plate 24 is fixedly installed on the side of the movable plate 12 near the driven plate 54. An adsorption groove 55 is opened on the driven plate 54 corresponding to the position of the adsorption plate 24. The size of the adsorption groove 55 is adapted to the size of the adsorption plate 24. An adsorption component is installed on the adsorption plate 24 corresponding to the position of the adsorption groove 55. The adsorption component includes, but is not limited to, an adsorption magnet. The adsorption plate 24 can adsorb and connect to the driven plate 54. In the initial state, when the movable plate 12 descends, the cooling gas transmitted in the cooling box 8 is transmitted into the working cylinder 5. At this time, the cooling chamber transmits the gas synchronously to the areas above and below the movable plate 12, enabling the cooling of the pull bar. When the movable plate 12 moves to the lowest position, the adsorption plate 24 on the movable plate 12 adsorbs the driven plate 54. At this time, when the movable plate 12 rises, it will drive the driven plate 54 to rise as well. The driven plate 54 will pull the baffle 58 to adapt and unfold, thereby reducing the size of the cooling chamber outlet in the cooling box 8. With the pressure remaining constant, the reduced outlet size will lead to an increase in the pressure of the discharged gas. At this time, the pull bar will be rapidly cooled, making it easier for the clamping conditions on the movable plate 12 to hold the pull bar.

[0038] Furthermore, when the movable plate 12 rises via the telescopic rod 10, the upward traction force causes the adsorption plate 24 and the driven plate 54 to separate, and the driven plate 54 will be affected by gravity to drive the baffle 58 to reset.

[0039] The working principle of this invention is: When the device of the present invention is used, before the operation begins, the raw material enters the hot melt processing component through the feed port for hot melt, and then is continuously discharged through the transmission component and the extrusion component 3 in a spiral extrusion manner. At this time, the telescopic control device 4 is activated, and the telescopic rod 10 drives the main adjusting plate 11 to move downward into the bottom of the main adjusting tank 9. When the main adjusting plate 11 stops due to restriction, the adjusting rod 45 continues to move downward. By driving the locking plate 51 from the adjusting plate 52 to retract into the locking rod 46, the lifting adjusting component and the slider 21 of the movable plate 12 are unlocked. At this time, the movable plate 12 completes the adsorption connection with the support plate 38 of the operation adjusting component through the adsorption component at the bottom of the slider 21.

[0040] Subsequently, the adjustment drive motor 7 starts and drives the drive gear 41 to rotate, causing the two sets of driven gears 39 to drive the drive gear 40 with a quarter turn of teeth to alternately mesh with the rack ring 37, thereby driving the movable rod 35 to reciprocate and rise under the limit of the retaining ring 36. Before the descent operation, the touch module on the trigger plate 23 will contact the trigger at the bottom of the movable touch control 43, causing the electric telescopic component 16 to drive the lifting plate 15 to descend in the adjustment groove 14, so that the clamping plate 31 will clamp the pull bar until the bottom of the trigger plate 23 contacts the trigger at the bottom of the moving groove 44. At this time, the electric telescopic component 16 will drive the lifting plate 15 to rise, so that the clamping plate 31 will no longer clamp the pull bar. At the same time, the cutting component will start to cut the pull bar until the touch module at the top of the trigger plate 23 contacts the trigger on the movable touch control 43 again, so that the clamping plate 31 clamps the pull bar again.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
