A waste plastic melting injection molding machine

Abstract

This invention belongs to the field of injection molding equipment technology, specifically a waste plastic melting injection molding machine, including a melting component, a transfer component, and a discharge component. The melting component is located at the center of the upper part of the transfer component, and the discharge component is located at the center of the lower part of the transfer component. The discharge component includes a stopper, a traction device, and a discharge end. After the nozzle injects molten plastic into the mold, during the mold transfer process, the tip of the molten material inside the mold will exhibit stringing due to the traction effect of the nozzle. Therefore, a stopper is installed at the top of the conical shell. A pressure device accelerates the downward discharge of the remaining molten material inside the conical shell, thereby completely discharging the molten material inside the conical shell. After the mold separates from the conical shell, there is no residual material inside the conical shell that causes stringing with the molten material inside the mold, thus avoiding the problem of unqualified quality caused by residual material cooling due to stringing at the top of the molded plastic.

Description

Technical Field

[0001] This invention belongs to the field of injection molding equipment technology, specifically a waste plastic melting injection molding machine. Background Technology

[0002] The application of plastics is becoming increasingly widespread, replacing metals, wood, paper, and other materials. With this widespread use, a large amount of waste plastics is generated. Due to their difficulty in degradation, disposal has become a major challenge, causing environmental pollution and wasting resources. The recycling and resource-based development of waste plastics reflects a profound understanding of the environment and resources, and represents a way of life that reduces environmental pollution and resource waste caused by waste plastics.

[0003] The existing publication number CN210999711U describes a waste plastic melting injection molding machine and method. It processes waste plastic by directly melting it with hot air and then injects it into an injection mold to perform injection molding. However, after the nozzle injects the molten plastic into the mold, during the transfer process, the tip of the molten material will exhibit stringing due to the dragging effect of the nozzle. This results in excess material on the top of the molded plastic, which requires secondary processing. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of stringing at the tip of the molten material due to the nozzle's pull in existing technologies, the present invention provides a waste plastic melting injection molding machine, comprising a melting component, a transfer component, and a discharge component. The melting component is located at the center of the upper part of the transfer component, and the discharge component is located at the center of the lower part of the transfer component. The discharge component includes a stopper, a traction device, and a discharge end: The traction device is sleeved on the outside of the blocking device, and the bottom of the traction device is inserted into the outer surface of the discharge end. The blocking device includes a guide end, a guide tube, a sliding sleeve, and a pressurizer; The top of the guide end is inserted into the bottom of the adapter component, the bottom end of the guide tube is inserted into the bottom of the inner cavity of the guide end through the through hole, the inner wall of the sliding sleeve is slidably connected to the outer surface of the guide tube, and the bottom end of the sliding sleeve extends into the interior of the discharge end. The pressurizer can pressurize the interior of the discharge component by pressurizing the interior of the sliding sleeve. The outer surface of the pressurizer is uniformly connected with connecting pipes, and the end of the connecting pipe away from the pressurizer is connected to the inner cavity of the sliding sleeve; the pressurizer pressurizes the inside of the discharge end by inflating air through the sliding sleeve, squeezing out the molten material remaining inside the discharge end, and cutting off the molten material connected to the sliding sleeve and the guide pipe.

[0005] Furthermore, the emission terminal includes: A container cone shell, wherein the top of the container cone shell is inserted into the bottom end of a sliding sleeve via a mating interface; An inner heating ring, the outer surface of which is sleeved with the upper part of the inner wall of the container cone shell; The control outer plate is symmetrically snapped onto both sides of the upper surface of the container cone shell, and the bottom of the inner cavity of the control outer plate is connected to the upper part of the inner cavity of the inner heating ring through a connecting wire. The control outer plate supplies power to the inner heating ring through the connecting wire, so as to raise the temperature inside the container cone shell, thereby ensuring that the molten plastic inside the container cone shell will not cool and solidify during injection molding.

[0006] Furthermore, the emission terminal also includes: The inner heat-insulating gasket has its outer surface fitted into the lower part of the inner wall of the container cone. The inner heat-insulating gasket is made of deformable soft steel. When the inner wall of the inner heat-insulating gasket is compressed, it will deform in the direction closer to the inner wall of the container cone. The pressure-sensitive buttons are evenly inserted into the outer surface of the container cone shell. The top of the pressure-sensitive buttons is pressed against the outer surface of the heat-insulating inner ring gasket, and the bottom of the pressure-sensitive buttons is connected to an adapter wire. The outer receiving ring has its outer surface snapped into the outer surface of the container cone shell, and the end of the adapter wire away from the pressure-sensing button is inserted into the inner cavity of the outer receiving ring. After the pressure-sensing button is triggered by the pressure of the heat-insulating inner ring pad, it will feed back the magnitude of the pressure to the outer receiving ring, thereby determining the internal pressure of the container cone shell.

[0007] Furthermore, the traction device includes: A retaining ring, wherein the inner wall of the retaining ring is sleeved with the outer surface of the guide end, and a circumferential groove is formed in the middle of the outer surface of the retaining ring. A pressure-controlled air box is evenly arranged in the inner cavity of the sleeve retaining ring. Both ends of the pressure-controlled air box are connected to a drain air pipe, and the end of the drain air pipe away from the pressure-controlled air box extends to the outside of the sleeve retaining ring through a circumferential groove. The adapter arm has a connecting plate inserted into its outer surface, and the outer surface of the connecting plate is inserted into the outer surface of the container cone. A sliding pull rod is inserted into the top of the adapter arm, and the top of the sliding pull rod is slidably connected to the bottom of the inner cavity of the pressure control air box. The pressure control air box pushes the sliding pull rod downward by pressurizing, thereby pulling the container cone down through the adapter arm, so that the bottom end of the container cone approaches the injection mold below. At this time, the sliding sleeve and the pressure device also slide down with the container cone.

[0008] Furthermore, the molten material component includes: A heating cylinder, wherein a partition component is provided at the bottom end of the heating cylinder; The pressure cap has symmetrical flip-up buckles on both sides of its upper surface. The lower surface of the pressure cap is inserted into the top of the inner wall of the heating cylinder, and the upper surface of the pressure cap is engaged with the outer surface of the heating cylinder through the flip-up buckles. A control top plate, the lower part of which is inserted into the upper surface of the heating cylinder; An internal rotating motor has a heating element inserted into the bottom end of its rotating shaft, and heat-conducting fan blades are symmetrically inserted into the outer surface of the heating element.

[0009] Furthermore, the partition component includes: The rotating bottom cover has an upper part of its outer surface that is rotatably connected to the bottom of the inner wall of the heating cylinder. Symmetrical docking ports are provided on both sides of the inner cavity of the rotating bottom cover. The bottom end of the heating element is rotatably connected to the axis of the inner wall of the rotating bottom cover. A plug-in rotating shaft is inserted into the center of the bottom of the rotating cover; A cutting plate is symmetrically inserted into the outer surface of the insertion shaft, and a remote control roller is connected to the end of the cutting plate away from the insertion shaft via a motor. The two sides of the cutting plate are designed with sharp surfaces to perform rotating cutting work. At the same time, the cutting plate itself is relatively thick, and a remote control roller with a motor for controlling the rotation is set in the hollowed-out inner cavity. Furthermore, the adapter component includes: A cylindrical container, wherein the axial center of the inner wall of the cylindrical container is rotatably connected to the outer surface of the insertable rotating shaft, and the axial center of the upper surface of the cylindrical container is rotatably connected to the bottom of the outer surface of the rotating bottom cover. An external rotating motor is evenly arranged inside the container shell, and the top end of the external rotating motor shaft extends to the outside of the container shell. An external rotating gear is inserted into the top end of the external rotating motor shaft. The outer surface of the external rotating gear is rotatably connected to the bottom of the outer surface of the rotating bottom cover. After the docking ports on both sides of the rotating bottom cover are docked with the two ports on both sides of the shaft of the container shell, the heating cylinder can pressurize the molten plastic inside into the container shell.

[0010] Furthermore, the adapter also includes: An arched support is provided, the upper surface of which is engaged with the bottom of the container shell. Reinforcing plates are symmetrically arranged on both sides of the upper surface of the arched support, and the outer surfaces of the reinforcing plates are pressed against the outer surfaces of the container shell. A protective sleeve is fitted, the bottom of which is inserted into the upper surface of the container shell, and the outer surface of the rotating bottom cover is inserted into the axis of the inner wall of the protective sleeve.

[0011] The beneficial effects of this invention are as follows: 1. This device can stir and melt plastic granules added to the heating cylinder, and then inject the molten material into the mold driven below for injection molding. However, after the nozzle injects the molten plastic into the mold, the top of the molten material inside the mold will exhibit stringing due to the drag effect of the nozzle during the mold transfer process. Therefore, an interruptor is installed at the top of the container cone shell, and a pressure device accelerates the discharge of the remaining molten material inside the container cone shell downwards, thereby completely discharging the molten material inside the container cone shell. After the mold and the container cone shell are separated, there is no residual material inside the container cone shell that causes stringing with the molten material inside the mold, thus avoiding the problem of the molded plastic top being defective due to residual material being cooled by stringing.

[0012] 2. During the discharge process of the container cone shell, the device controls the outer plate to supply power to the inner heating ring, so that the inner heating ring heats the inside of the container cone shell. This prevents the molten material from cooling down inside the container cone shell and solidifying on the inner wall of the container cone shell, thus preventing the bottom opening of the container cone shell from being blocked. Therefore, the molten material will not solidify due to heat absorption after entering the container cone shell, which would cause discharge difficulties.

[0013] 3. When the molten material is discharged downwards from the container cone, the molten material component of the device uses pressure to squeeze the molten material downwards. Therefore, when the molten material is discharged, it will compress the inner wall of the heat insulation inner ring gasket, thereby deforming the heat insulation inner ring gasket and compressing the pressure-sensitive button. The actual pressure inside the container cone is fed back through the outer receiving ring, thereby achieving the pressure control effect. This avoids the problem of excessive pressure applied by the pressure cover, which would cause the container cone to discharge too much material and overflow the mold.

[0014] 4. During the process of stopping the discharge, the cutting plate will cut off the molten material inside the heating cylinder from the molten material inside the discharge component below through its sharp side. The cutting plate will also block the openings on both sides of the shaft of the container shell. Therefore, the pressure booster will not actually perform reverse pressure work on the large-volume heating cylinder, thereby greatly reducing the actual power requirement of the pressure booster, so as to use a smaller pressure booster and achieve the effect of saving costs.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a waste plastic melting injection molding machine, comprising a melting component 1, a transfer component 2, and a discharge component 3. The melting component 1 is located at the center of the upper part of the transfer component 2, and the discharge component 3 is located at the center of the lower part of the transfer component 2. The discharge component 3 includes a stopper 31, a traction device 32, and a discharge end 33. The traction device 32 is sleeved on the outside of the blocking device 31, and the bottom of the traction device 32 is inserted into the outer surface of the discharge end 33. The blocking device 31 includes a guide end 311, a guide tube 312, a sliding sleeve 313, and a pressurizer 314; The top of the guide end 311 is inserted into the bottom of the adapter 2, the bottom end of the guide tube 312 is inserted into the bottom of the inner cavity of the guide end 311 through the through hole, the inner wall of the sliding sleeve 313 is slidably connected to the outer surface of the guide tube 312, the bottom end of the sliding sleeve 313 extends into the interior of the discharge end 33, and the pressure device 314 can pressurize the interior of the discharge component 3 by pressurizing the interior of the sliding sleeve 313; The outer surface of the pressure device 314 is uniformly connected with connecting pipes, and the end of the connecting pipe away from the pressure device 314 is connected to the inner cavity of the sliding sleeve 313. The pressure device 314 pressurizes the inside of the discharge end 33 by the sliding sleeve 313, squeezes out the molten material remaining inside the discharge end 33, and cuts off the molten material connected to the sliding sleeve 313 and the guide pipe 312.

[0019] The emission end 33 includes: The container cone shell 331 is connected to the bottom end of the sliding sleeve 313 via a mating interface at the top of the cone shell 331. The inner heating ring 332 has its outer surface fitted into the upper part of the inner wall of the container cone shell 331. The outer control plate 333 is symmetrically snapped onto both sides of the upper surface of the container cone shell 331. The bottom of the inner cavity of the outer control plate 333 is connected to the upper part of the inner cavity of the inner heating ring 332 through the connecting wire. The outer control plate 333 supplies power to the inner heating ring 332 through the connecting wire, so that the inside of the container cone shell 331 is heated, thereby ensuring that the molten plastic inside the container cone shell 331 will not cool and solidify during injection molding.

[0020] The emission terminal 33 also includes: The inner heat insulation gasket 334 has its outer surface fitted with the lower part of the inner wall of the container cone 331. The inner heat insulation gasket 334 is made of deformable soft steel. When the inner wall of the inner heat insulation gasket 334 is compressed, it will deform towards the inner wall of the container cone 331. The pressure-sensitive button 335 is evenly inserted into the outer surface of the container cone shell 331. The top of the pressure-sensitive button 335 is pressed against the outer surface of the heat-insulating inner ring pad 334, and the bottom of the pressure-sensitive button 335 is connected to the adapter wire 336. The outer receiving ring 337 has its outer surface snapped into the outer surface of the container cone shell 331, and the end of the adapter wire 336 away from the pressure-sensing button 335 is inserted into the inner cavity of the outer receiving ring 337. After the pressure-sensing button 335 is triggered by the heat-insulating inner ring pad 334, it will feed back the magnitude of the pressure to the outer receiving ring 337, thereby determining the internal pressure of the container cone shell 331.

[0021] The traction device 32 includes: A retaining ring 321 is provided, the inner wall of which is sleeved with the outer surface of the guide end 311, and a circumferential groove is provided in the middle of the outer surface of the retaining ring 321. The pressure control air box 322 is evenly arranged in the inner cavity of the sleeve retaining ring 321. Both ends of the pressure control air box 322 are connected to the drainage air pipe 323, and the end of the drainage air pipe 323 away from the pressure control air box 322 extends to the outside of the sleeve retaining ring 321 through the surrounding groove. The adapter arm 325 has a connecting plate inserted into its outer surface, and the outer surface of the connecting plate is inserted into the outer surface of the container cone shell 331. A sliding pull rod 324 is inserted into the top of the adapter arm 325, and the top of the sliding pull rod 324 is slidably connected to the bottom of the inner cavity of the pressure control air box 322. The pressure control air box 322 pushes the sliding pull rod 324 downward by pressurizing, thereby pulling the container cone shell 331 down through the adapter arm 325, so that the bottom end of the container cone shell 331 is close to the injection mold below. At this time, the sliding sleeve 313 and the pressure device 314 also slide down with the container cone shell 331.

[0022] After the processed plastic granules are fed into the melting component 1, the melting component 1 heats the plastic to melt it into a near-fluid gel, which is then stored inside the melting component 1. After a mold is placed at the axis at the bottom of the device, the melting component 1 pressurizes the plastic inside into the discharge component 3, and the discharge component 3 injects the molten material into the mold.

[0023] When the molten material is injected into the mold, the traction device 32 located outside the guide end 311 drives the container cone 331 to descend by pushing the adapter arm 325, so that the bottom end of the container cone 331 is inserted into the interior of the mold below. As the molten material is discharged, the container cone 331 is gradually lifted upward, thereby realizing the filling operation.

[0024] After the filling in a single mold is almost complete, the pressure pressurizer 314 begins to pressurize the inside of all sliding sleeves 313. At this time, the molten material inside the guide end 311 flows upward back, and the remaining molten material inside the container cone 331 is discharged downward at an accelerated speed, thereby completely discharging the molten material inside the container cone 331. After the mold and the container cone 331 are separated, there is no residual material inside the container cone 331 that causes stringing with the molten material inside the mold.

[0025] During the material discharge process of the container cone shell 331, the outer plate 333 controls the power supply to the inner heating ring 332 so that the inner heating ring 332 heats the inside of the container cone shell 331. This prevents the molten material from cooling down inside the container cone shell 331 and solidifying on the inner wall of the container cone shell 331, thus preventing the bottom opening of the container cone shell 331 from being blocked.

[0026] When the molten material is discharged downwards from the container cone 331, the molten material component 1 of the device uses pressure to squeeze the molten material downwards. Therefore, when the molten material is discharged, it will squeeze the inner wall of the heat insulation inner ring gasket 334, thereby deforming the heat insulation inner ring gasket 334 and squeezing the pressure-sensitive button 335. The actual pressure inside the container cone 331 is fed back through the outer receiving ring 337, thereby achieving the pressure control effect.

[0027] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the molten material component 1 includes: Heating cylinder 11, with a partition component 4 at the bottom end; The pressure cover 13 has flip-up buckles 12 symmetrically arranged on both sides of its upper surface. The lower surface of the pressure cover 13 is inserted into the top of the inner wall of the heating cylinder 11, and the upper surface of the pressure cover 13 is engaged with the outer surface of the heating cylinder 11 through the flip-up buckles 12. Control top plate 14, the lower part of control top plate 14 is inserted into the upper surface of heating cylinder 11; An internal rotating motor 15 has a heating element 16 inserted into the bottom end of its rotating shaft, and heat-conducting fan blades 17 are symmetrically inserted into the outer surface of the heating element 16.

[0028] Partition component 4 includes: Rotate the bottom cover 41. The upper part of the outer surface of the rotating bottom cover 41 is rotatably connected to the bottom of the inner wall of the heating cylinder 11. Symmetrical docking ports 42 are opened on both sides of the inner cavity of the rotating bottom cover 41. The bottom end of the heating element 16 is rotatably connected to the axis of the inner wall of the rotating bottom cover 41. Insert the rotating shaft 43, and insert the top end of the rotating shaft 43 into the axis at the bottom of the rotating bottom cover 41; A cutting plate 44 is symmetrically inserted into the outer surface of the insertion shaft 43. The end of the cutting plate 44 away from the insertion shaft 43 is connected to a remote control roller 45 via a motor. The two sides of the cutting plate 44 are designed with sharp surfaces to perform rotating cutting work. The cutting plate 44 itself is relatively thick, and a remote control roller 45 with a motor for controlling the rotation is set in the hollowed-out inner cavity. Adapter component 2 includes: The inner wall of the container round shell 23 is rotatably connected to the outer surface of the plug-in rotating shaft 43 at the axis, and the upper surface of the container round shell 23 is rotatably connected to the bottom of the outer surface of the rotating bottom cover 41 at the axis. An external rotating motor 25 is evenly arranged in the inner cavity of the container round shell 23, and the top end of the rotating shaft of the external rotating motor 25 extends to the outside of the container round shell 23. An external rotating gear 26 is inserted into the top end of the rotating shaft of the external rotating motor 25. The outer surface of the external rotating gear 26 is rotatably connected to the bottom of the outer surface of the rotating bottom cover 41. After the docking ports 42 on both sides of the rotating bottom cover 41 are docked with the two ports on both sides at the axis of the container round shell 23, the heating cylinder 11 can pressurize the molten plastic inside into the interior of the container cone shell 331.

[0029] Adapter component 2 also includes: An arched support 21 is attached to the bottom of a container shell 23. Reinforcing plates 22 are symmetrically arranged on both sides of the upper surface of the arched support 21. The outer surface of the reinforcing plates 22 is pressed against the outer surface of the container shell 23. The protective shell 24 is fitted in, and the bottom of the protective shell 24 is inserted into the upper surface of the container round shell 23. The outer surface of the rotating bottom cover 41 is inserted into the axis of the inner wall of the protective shell 24.

[0030] After the plastic granules are stored inside the heating cylinder 11, the operator places the pressure cap 13 on the top of the heating cylinder 11 and reinforces the pressure cap 13 with the flip buckles 12 on both sides. Then, the internal rotating motor 15 starts to rotate the already heated heating element 16. When the heat-conducting fan blade 17 rotates, it breaks up the granules. After the granules fully absorb heat, they melt quickly to form molten material. During the discharge process, the pressure cap 13 squeezes the molten material downward by applying pressure inside the heating cylinder 11.

[0031] Since the actual power of the pressurizer 314 is insufficient to push the large amount of molten material inside the heating cylinder 11 upwards, during the process of stopping the discharge, the scissor-shaped rotating plates 44 located on both sides of the bottom of the rotating cover 41 will drive the rotating cover 41 to rotate relative to the heating cylinder 11 by actively twisting the remote control rollers 45. During the rotation of the rotating cover 41, the scissor-shaped rotating plates 44 will cut off the molten material inside the heating cylinder 11 from the molten material inside the discharge component 3 below through their sharp sides, and the scissor-shaped rotating plates 44 will block the openings on both sides of the shaft of the container shell 23. At this time, the pressurizer 314 will not pressurize the inside of the heating cylinder 11.

[0032] When there is a lot of molten material inside the heating cylinder 11, the load is too large if the rotating bottom cover 41 is driven to rotate by the cutting plate 44 alone. At this time, the external rotating motor 25 can drive the container shell 23 to rotate by rotating the external rotating gear 26, and then the cutting effect is achieved by the sharp side of the cutting plate 44.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
