Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of plastic masterbatch production equipment, specifically relating to a modified plastic masterbatch production device. Background Technology
[0002] Modified plastic masterbatch is a pre-prepared, homogeneous mixture of high-concentration functional additives and carrier resin, typically existing in granular form. It is one of the core raw materials for achieving high-performance, functionalized, and customized plastics in the modern plastics industry. Modified plastic masterbatch is an indispensable "industrial MSG" and "functional chip" in the modern plastics industry. It uses advanced processing technology to pre-disperse and stabilize various fine functional additives uniformly in the carrier resin, forming easy-to-use granules. Downstream plastic product manufacturers only need to mix it with the base resin in the correct proportions to efficiently and stably produce high-performance or functional plastic products that meet specific performance requirements.
[0003] Existing production equipment typically includes a drying source; however, this is usually a single heating plate or localized direct hot air blowing. The masterbatch has a short movement path and insufficient residence time within the equipment. At the same time, the masterbatch is prone to accumulation, causing some particles to be blocked, resulting in significant differences in the contact area and time with the heat source. This easily leads to incomplete drying or localized over-drying, resulting in poor consistency in the product's moisture content, which in turn affects the melting uniformity in subsequent processing. In addition, plastic masterbatch is prone to sticking together and forming clumps during extrusion, requiring additional manual or equipment-based secondary separation. This not only increases production steps and costs but may also further damage the masterbatch morphology due to the separation operation. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a modified plastic masterbatch production device.
[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a modified plastic masterbatch production device, including a fixed mounting shell, a masterbatch feeding pipe fixedly connected to one side of the fixed mounting shell, a mounting back plate fixedly connected to the end of the masterbatch feeding pipe away from the fixed mounting shell, the mounting back plate being fixedly installed to the masterbatch extrusion end assembly by multiple sets of bolts, a feeding channel being opened on the fixed mounting shell corresponding to the position of the masterbatch feeding pipe, and a moving extension mechanism being fixedly connected to the middle of the inner wall of the fixed mounting shell; the moving extension mechanism includes a fixed cylinder fixedly installed between the fixed mounting shell and the fixed mounting shell, an electrically heated material distribution plate being fixedly installed on the inner wall of the fixed mounting shell, and a hot air drying mechanism being fixedly installed on the outer side of the fixed mounting shell.
[0006] Furthermore, an installation ring is fixedly connected to the fixed cylinder, and multiple evenly distributed stepped buffer plates are fixedly connected to the outer circumference of the installation ring. A guide arc plate is fixedly connected to the electric heating material distribution plate, and one end of the guide arc plate is fixedly connected to the inner wall of the fixed installation shell near the feed channel. The stepped buffer plate is set with an inclined structure, and the inclination direction of the stepped buffer plate is opposite to the rotation direction of the plastic masterbatch.
[0007] Through the above technical solution, after the plastic masterbatch enters along the involute angle of the fixed installation shell, it is guided by the guide arc plate and then rotates and falls onto the stepped buffer plate below along the direction of the electrically heated material distribution plate after entering the fixed installation shell.
[0008] Furthermore, a centrifugal dispersion hood is fixedly connected to the lower end of the fixed mounting shell. The centrifugal dispersion hood is funnel-shaped, and a guide cylinder is fixedly installed at the lower end of the centrifugal dispersion hood. A buffer pad made of rubber is fixedly installed on the inner wall of the centrifugal dispersion hood.
[0009] Through the above technical solution, when the plastic masterbatch is thrown outward to the inside of the centrifugal dispersion hood under the action of centrifugal force, the setting of the buffer pad can buffer the dry plastic masterbatch and avoid the loss of material due to large impact.
[0010] Furthermore, the masterbatch feed pipe is set along the involute angle of the fixed mounting shell, and the feed channel and the masterbatch feed pipe are interconnected.
[0011] With the above technical solution, the plastic masterbatch fed along the masterbatch feeding pipe will be fed along the involute of the fixed installation shell. The buffering effect of the involute will make the plastic masterbatch rotate smoothly after entering the fixed installation shell, avoiding the violent impact caused by sudden deceleration and preventing the freshly extruded plastic masterbatch from deforming under violent impact.
[0012] Furthermore, the electrically heated bulk material plate is arranged in an inclined annular structure. The plastic masterbatch enters along the involute angle of the fixed mounting shell. After being guided by the guide arc plate, the plastic masterbatch enters the fixed mounting shell and rotates along the electrically heated bulk material plate. The rotation speed gradually decreases, and then the plastic masterbatch will naturally slide from the inside of the electrically heated bulk material plate to the stepped buffer plate below.
[0013] With the above technical solution, the stepped buffer plate covers the entire space between the electric heating material distribution plate and the heat collection plate. The plastic masterbatch falling onto the stepped buffer plate will continue to climb the slope along the stepped buffer plate due to inertia. At this time, the speed of the plastic masterbatch will decrease rapidly, and during the climbing process, most of the plastic masterbatch will fall back down through the gaps between multiple stepped buffer plates due to gravity. The whole process can increase the drying time of the plastic masterbatch when it falls.
[0014] Furthermore, a servo motor is fixedly installed inside the fixed cylinder, and a drive shaft is fixedly connected to the output end of the servo motor. A fixed platform is fixedly connected to one end of the drive shaft, and a rotating disk is fixedly connected to the side of the fixed platform away from the drive shaft. The rotating disk is rotatably connected to the fixed cylinder, and the rotating disk is set with an inclined structure. The inclination direction of the rotating disk is opposite to the inclination direction of the centrifugal dispersion hood.
[0015] With the above technical solution, when the dried plastic masterbatch falls onto the rotating disk, the servo motor power is turned on, and the drive shaft drives the fixed table to rotate, so that the fixed table transmits power to the rotating disk. The plastic masterbatch falling on the rotating disk is thrown outward under the action of centrifugal force, thereby colliding with the inside of the centrifugal dispersion hood, thus separating the plastic masterbatch that is stuck together, and falling into the collection container through the guide cylinder.
[0016] Furthermore, the hot air drying mechanism includes two elongated air blowing holes opened at the top of the front and rear ends of the fixed mounting shell, and the elongated air blowing holes are inclined holes that slope towards the electric heating material distribution plate. Air guide mounting covers are fixedly installed on the outer side of the two elongated air blowing holes. A flow guide mounting plate is fixedly connected to one side of the center of the air guide mounting cover. An air guide pipe is fixedly connected to one end of the two air guide mounting covers. An mounting ring seat is fixedly connected to the outer wall of the fixed mounting shell. An mounting side plate is fixedly installed on one side of the mounting ring seat. A fixed fan is fixedly connected to the mounting side plate. The other end of the two air guide pipes is connected to the air outlet of the fixed fan.
[0017] With the above technical solution, since the air guide mounting cover is relatively long, a flow guide mounting plate is fixedly connected to one side of the center of the air guide mounting cover. By designing the flow guide mounting plate, the hot air entering the air guide mounting cover can be diverted under the action of the flow guide mounting plate, thereby better ensuring the uniformity of the air outlet of the long strip air blowing hole, and thus ensuring the dehumidification and drying effect. Furthermore, since the long strip air blowing hole is an inwardly inclined oblique hole structure, the air direction can be aligned with the top of the electric heating material distribution plate, thereby accelerating the drying speed of the plastic masterbatch.
[0018] Furthermore, a heat collection plate is fixedly connected to the lower end of the fixed mounting shell, and the air inlet of the fixed fan is connected to the space between the heat collection plate and the electric heating material distribution plate.
[0019] Through the above technical solution, the fixed fan will draw hot air between the electric heating material distribution plate and the heat collection plate, and send the hot air into two air guide installation covers through two air guide pipes. Then the hot air will be blown into the electric heating material distribution plate through the corresponding long air blowing holes, and quickly dry and dehumidify the plastic masterbatch rolling off the electric heating material distribution plate.
[0020] Furthermore, a fixed heating coil is installed inside the electrically heated material plate.
[0021] Through the above technical solution, a fixed heating coil is installed inside the electric heating bulk material plate, which causes the electric heating bulk material plate to heat up, thereby heating and drying the naturally rolling plastic masterbatch.
[0022] The beneficial effects of the present invention are as follows: (1) The present invention designs a motion extension mechanism, and through the rotational flow method, the plastic masterbatch enters the fixed installation shell and rotates along the electric heating material plate. The rotation speed gradually decreases, and then the plastic masterbatch will naturally slide from the inner side of the electric heating material plate to the step buffer plate below. The plastic masterbatch that falls onto the step buffer plate will continue to climb along the step buffer plate by inertia. At this time, the speed of the plastic masterbatch will decrease rapidly, and during the climbing process, most of the plastic masterbatch will fall back down through the gaps between multiple step buffer plates due to gravity. In the whole process, the residence time of the plastic masterbatch during feeding can be extended to a certain extent, thereby achieving a better dehumidification and drying effect. At the same time, during the climbing process, the plastic masterbatch will produce irregular rolling and collision due to the reverse action of gravity and the inclination of the step buffer plate. This movement can break the slight adhesion that may be formed due to the high temperature when it is first extruded. (2) The invention designs a hot air drying mechanism to send the hot air between the electric heating material plate and the heat collection plate into two air guide installation covers through two air guide pipes to quickly dry and dehumidify the plastic masterbatch rolling off the electric heating material plate. On the one hand, it can accelerate the drying process of the plastic masterbatch by means of hot air flow. At the same time, it can also extend the residence time of the plastic masterbatch on the electric heating material plate to a certain extent, thereby achieving a better dehumidification and drying effect. (3) The invention uses a rotating disk. When the dried plastic masterbatch falls onto the rotating disk, the servo motor power is started and the drive shaft drives the fixed table to rotate, so that the fixed table transmits power to the rotating disk. The plastic masterbatch falling on the rotating disk is thrown outward under the action of centrifugal force, so that it collides with the inside of the centrifugal dispersion cover, thereby separating the plastic masterbatch that is still stuck together and falling into the collection container through the guide cylinder.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0026] like Figures 1-3 As shown, a modified plastic masterbatch production device of this embodiment includes a fixed mounting shell 1. A masterbatch feeding pipe 14 is fixedly connected to one side of the fixed mounting shell 1. A mounting back plate 15 is fixedly connected to the end of the masterbatch feeding pipe 14 away from the fixed mounting shell 1. The mounting back plate 15 is fixedly installed to the masterbatch extrusion end assembly by multiple sets of bolts. A feeding channel 16 is opened on the fixed mounting shell 1 at the position corresponding to the masterbatch feeding pipe 14. A moving extension mechanism 2 is fixedly connected to the middle of the inner wall of the fixed mounting shell 1. The moving extension mechanism 2 includes a fixed cylinder 21 fixedly installed between the fixed mounting shell 1 and the fixed mounting shell 1. An electrically heated material distribution plate 20 is fixedly installed on the inner wall of the fixed mounting shell 1. A hot air drying mechanism 4 is fixedly installed on the outer side of the fixed mounting shell 1.
[0027] like Figures 1-4As shown, a mounting ring 23 is fixedly connected to the fixed cylinder 21. Multiple evenly distributed stepped buffer plates 24 are fixedly connected to the outer circumference of the mounting ring 23. A guide arc plate 22 is fixedly connected to the electrically heated material distribution plate 20. One end of the guide arc plate 22 is fixedly connected to the inner wall of the fixed mounting shell 1 near the feed channel 16. The stepped buffer plates 24 are set with an inclined structure, and the inclination direction of the stepped buffer plates 24 is opposite to the rotation direction of the plastic masterbatch. After the plastic masterbatch enters the fixed mounting shell 1 at an involute angle, it is guided by the guide arc plate 22, so that after entering the fixed mounting shell 1, the plastic masterbatch rotates and falls onto the stepped buffer plate 24 below along the direction of the electrically heated material distribution plate 20.
[0028] like Figure 1 As shown, a centrifugal dispersion hood 11 is fixedly connected to the lower end of the fixed mounting shell 1. The centrifugal dispersion hood 11 is funnel-shaped. A guide cylinder 12 is fixedly installed at the lower end of the centrifugal dispersion hood 11. A buffer pad is fixedly installed on the inner wall of the centrifugal dispersion hood 11. The buffer pad is made of rubber. When the plastic masterbatch is thrown outward to the inner side of the centrifugal dispersion hood 11 under the action of centrifugal force, the buffer pad can buffer the dry plastic masterbatch and avoid large impacts that cause material loss.
[0029] like Figures 1-2 As shown, the masterbatch feeding pipe 14 is set along the involute angle of the fixed mounting shell 1, and the feeding channel 16 is interconnected with the masterbatch feeding pipe 14. The plastic masterbatch input along the masterbatch feeding pipe 14 will be fed along the involute of the fixed mounting shell 1. Utilizing the buffering effect of the involute, the plastic masterbatch rotates smoothly after entering the fixed mounting shell 1, avoiding the violent impact caused by sudden deceleration, and preventing the freshly extruded plastic masterbatch from deforming under violent impact.
[0030] like Figures 1-6 As shown, the electric heating material distribution plate 20 is arranged in an inclined annular structure. The plastic masterbatch enters along the involute angle of the fixed mounting shell 1. After being guided by the guide arc plate 22, the plastic masterbatch enters the fixed mounting shell 1 and rotates along the electric heating material distribution plate 20. The rotation speed gradually decreases. Then, the plastic masterbatch will naturally slide down from the inside of the electric heating material distribution plate 20 to the stepped buffer plate 24 below. The stepped buffer plate 24 covers the entire space between the electric heating material distribution plate 20 and the heat collection plate 3. The plastic masterbatch falling on the stepped buffer plate 24 will continue to climb uphill along the stepped buffer plate 24 by inertia. At this time, the speed of the plastic masterbatch will decrease rapidly. During the climbing process, most of the plastic masterbatch will fall back down through the gaps between multiple stepped buffer plates 24 due to gravity. The whole process can increase the drying time of the plastic masterbatch during the falling process.
[0031] like Figures 1-3As shown, a servo motor 5 is fixedly installed inside the fixed cylinder 21. The output end of the servo motor 5 is fixedly connected to a drive shaft 50. One end of the drive shaft 50 is fixedly connected to a fixed platform 51. A rotating disk 52 is fixedly connected to the side of the fixed platform 51 away from the drive shaft 50. The rotating disk 52 is rotatably connected to the fixed cylinder 21. The rotating disk 52 is set with an inclined structure. The inclination direction of the rotating disk 52 is opposite to the inclination direction of the centrifugal dispersion hood 11. When the dried plastic masterbatch falls onto the rotating disk 52, the servo motor 5 is powered on, and the drive shaft 50 drives the fixed platform 51 to rotate, so that the fixed platform 51 transmits power to the rotating disk 52. The plastic masterbatch falling onto the rotating disk 52 is thrown outward under the action of centrifugal force, thereby colliding with the inside of the centrifugal dispersion hood 11, thereby separating the plastic masterbatch that is stuck together, and falling into the collection container through the guide cylinder 12.
[0032] like Figures 1-5 As shown, the hot air drying mechanism 4 includes two elongated air blowing holes 13 located at the top of the front and rear ends of the fixed mounting shell 1. Each elongated air blowing hole 13 is an inclined hole structure sloping towards the electrically heated material distribution plate 20. Air guide mounting covers 43 are fixedly installed on the outer sides of both elongated air blowing holes 13. A guide mounting plate 44 is fixedly connected to one side of the center of the air guide mounting cover 43. Air guide pipes 45 are fixedly connected to one end of each of the two air guide mounting covers 43. A mounting ring seat 40 is fixedly connected to the outer wall of the fixed mounting shell 1. A mounting side plate 41 is fixedly installed on one side of the mounting ring seat 40. A fixed fan 42 is fixedly connected to the mounting side plate 41. The two guide... The other end of the air duct 45 is connected to the air outlet of the fixed fan 42. Since the air guide mounting cover 43 is relatively long, a flow guide mounting plate 44 is fixedly connected to one side of the center of the air guide mounting cover 43. By designing the flow guide mounting plate 44, the hot air entering the air guide mounting cover 43 can be diverted under the action of the flow guide mounting plate 44, so as to better ensure the uniformity of the air outlet of the long strip air hole 13, thereby ensuring the dehumidification and drying effect. Furthermore, since the long strip air hole 13 is an inward inclined oblique hole structure, the air direction can be aligned with the top of the electric heating material plate 20, which accelerates the drying speed of the plastic masterbatch.
[0033] like Figures 1-3 As shown, a heat collection plate 3 is fixedly connected to the lower end of the fixed mounting shell 1. The air inlet of the fixed fan 42 is connected to the space between the heat collection plate 3 and the electric heating material distribution plate 20. The fixed fan 42 will draw hot air between the electric heating material distribution plate 20 and the heat collection plate 3 and send the hot air through two air guide pipes 45 into two air guide mounting covers 43. Then the hot air will be blown into the electric heating material distribution plate 20 through the corresponding long air blowing hole 13, and quickly dry and dehumidify the plastic masterbatch rolling off the electric heating material distribution plate 20.
[0034] like Figure 10As shown, a fixed heating coil 6 is installed inside the electric heating material distribution plate 20. The fixed heating coil 6 installed inside the electric heating material distribution plate 20 causes the electric heating material distribution plate 20 to heat up, thereby heating and drying the naturally falling plastic masterbatch.
[0035] The working principle of this embodiment is as follows: the masterbatch extrusion end assembly extrudes the plastic masterbatch through the masterbatch feeding pipe 14 and feed channel 16 into the fixed mounting shell 1. Since the masterbatch extrusion end assembly is at a high position, the plastic masterbatch has a gravitational acceleration after extrusion, and the input plastic masterbatch will feed along the involute of the fixed mounting shell 1. An electric heating material distribution plate 20 is fixedly connected to the middle of the inner wall of the fixed mounting shell 1. The electric heating material distribution plate 20 is set in an inclined circular structure. After the plastic masterbatch enters the fixed mounting shell 1 at an involute angle, it is guided by the guide arc plate 22. After entering the fixed mounting shell 1, the plastic masterbatch rotates along the electric heating material distribution plate 20. The rotation speed gradually decreases. Then the plastic masterbatch will naturally slide from the inner side of the electric heating material distribution plate 20 onto the stepped buffer plate 24 below. Multiple evenly distributed stepped buffer plates 24 are fixedly connected to the mounting ring 23 between the lower side of the electric heating material distribution plate 20 and the heat collection plate 3. The stepped buffer plates 24 cover the entire space between the electric heating material distribution plate 20 and the heat collection plate 3. The plastic masterbatch falling onto the stepped buffer plate 24 will continue to climb uphill along the stepped buffer plate 24 due to inertia. At this time, the speed of the plastic masterbatch will decrease rapidly, and during the climbing process, most of the plastic masterbatch will fall back down through the gaps between the multiple stepped buffer plates 24 due to gravity. The whole process can increase the drying time of the plastic masterbatch when it falls. After the plastic masterbatch flows down from the stepped buffer plate 24, it can naturally slide onto the rotating disk 52. At this time, the fixed fan 42 will draw the hot air between the electric heating material distribution plate 20 and the heat collection plate 3, and send the hot air into the two air guide mounting covers 43 through the two air guide pipes 45. Then the hot air will be blown into the electric heating material distribution plate 20 through the corresponding long air blowing holes 13, and quickly dry and dehumidify the plastic masterbatch rolling down the electric heating material distribution plate 20. On the one hand, the drying process of the plastic masterbatch can be accelerated by the flow of hot air. At the same time, it can also prolong the residence time of the plastic masterbatch on the electric heating material distribution plate 20 to a certain extent, thereby achieving a better dehumidification and drying effect. When the dried plastic masterbatch falls onto the rotating disk 52, the servo motor 5 starts up, and the drive shaft 50 drives the fixed table 51 to rotate, so that the fixed table 51 transmits power to the rotating disk 52. The plastic masterbatch falling on the rotating disk 52 is thrown outward under the action of centrifugal force, thereby colliding with the inside of the centrifugal dispersion hood 11, thereby separating the plastic masterbatch that is stuck together, and falling into the collection container through the guide cylinder 12.
