Technical Field
[0001] This utility model relates to the field of plastic masterbatch production technology, specifically a transparent plastic masterbatch production device. Background Technology
[0002] Plastics are polymers made from monomers through addition or condensation polymerization. They have moderate resistance to deformation, falling between fibers and rubber, and are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.
[0003] Plastic masterbatch is a basic raw material in the plastics processing industry. It is processed through specific processes and has a uniform composition and properties. Plastic masterbatch production equipment is a mechanical equipment system used to produce this masterbatch. It integrates multiple functional parts such as feeding, mixing, extrusion, cooling and pelletizing. Through a series of physical and chemical processes, it transforms raw materials into high-quality plastic masterbatch.
[0004] Existing methods require screening after extruding plastic masterbatch. However, multiple sieves are typically used for grading during screening. When there is too much masterbatch, it accumulates in the sieves, causing blockage of the sieve mesh.
[0005] Therefore, a transparent plastic masterbatch production device is proposed to address the above problems. Utility Model Content

When the sieve barrel and the cleaning rod come into contact, they are also pushed by the bristles on the cleaning rod, causing the transparent plastic masterbatch blocking the mesh of the sieve barrel to move, thus unlocking the movement path and increasing the cleaning of the sieve barrel.
[0008] Preferably, the bottom of the screening barrel is fixedly connected to multiple air blowing pipes; the ends of the air blowing pipes are connected to air jet heads; the bottom of the air blowing pipes is connected to a connecting pipe; when rotating inside the screening barrel, the connecting pipe can be connected to an air pump, and the airflow is transmitted through the connecting pipe into the air blowing pipe, and finally sprayed out from the air jet head from the bottom of the screening barrel to contact the transparent plastic masterbatch. Upon contact, the transparent plastic masterbatch is blown, causing it to gradually rise and then fall, thereby increasing the movement of the transparent plastic masterbatch inside the screening barrel and increasing its contact with the mesh holes of the screening barrel; by adding air jet heads, the transparent plastic masterbatch inside the screening barrel can be blown, increasing its movement area inside the screening barrel, thereby making it more comprehensive when in contact with the screening barrel, increasing its contact with the screening barrel and thus accelerating the separation of the transparent plastic masterbatch.
[0009] Preferably, a rubber sheet is installed on the top of the jet head; the rubber sheet and the jet head are connected by fixing screws; by adding the rubber sheet, the surrounding transparent plastic masterbatch can be intercepted when the airflow passes through the jet head, so as to reduce its impact on the airflow ejected from the jet head.
[0010] Preferably, a pair of fixing rods are fixedly connected to the top of the screen barrel; a lifting plate is fixedly connected to the top of the fixing rods; by adding the lifting plate, multiple force points can be added when the screen barrel is lifted, so that it can be quickly raised and leave the interior of the screen barrel.
[0011] Preferably, a connecting plate is fixedly attached to the surface of the connecting pipe; a semiconductor cooler is fixedly attached to the surface of the connecting plate; the output end of the semiconductor cooler is located inside the connecting pipe; by adding a semiconductor cooler, the airflow can be cooled, and after cooling, the heat generated by the friction between transparent plastic masterbatches can be reduced.
[0012] Preferably, a clamping plate is provided at the top of the feed inlet; the clamping plate and the feed inlet are correspondingly provided; by adding the clamping plate, the screening bucket can be closed, thus increasing its protection when placed.
[0013] The advantages of this utility model are:
[0014] 1. The transparent plastic masterbatch production device of this utility model uses a screen barrel to filter the transparent plastic masterbatch. During filtration, centrifugal force squeezes smaller particles out of the screen barrel, while larger particles are intercepted and remain inside the screen barrel. When the screen barrel comes into contact with the cleaning rod, it is also pushed by the bristles on the cleaning rod, causing the transparent plastic masterbatch blocking the screen barrel mesh to move and unlock its movement path, thereby increasing the cleaning of the screen barrel.
[0015] 2. The transparent plastic masterbatch production device of this utility model can blow the transparent plastic masterbatch inside the screen barrel by adding an air jet, thereby increasing the area on which it moves inside the screen barrel, so that it can come into more comprehensive contact with the screen barrel, thereby increasing the contact with the screen barrel and accelerating the separation of the transparent plastic masterbatch.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a transparent plastic masterbatch production device includes a screening barrel 1, a support frame 11 fixedly connected to the side wall of the screening barrel 1; a cover plate 12 is installed on the top of the support frame 11; the cover plate 12 and the support frame 11 are connected by multiple bolts; a feed inlet 13 is opened on the top of the cover plate 12; a rotary motor 15 and multiple cleaning motors 101 are sequentially fixedly connected to the bottom of the screening barrel 1; a round rod 16 is fixedly connected to the output end of the rotary motor 15; the round rod 16 is through-mounted and rotatably connected to the support frame 11; a screen barrel 19 is slidably fitted in the middle of the round rod 16; a mounting plate 17 is threadedly connected to the end of the round rod 16; the mounting plate 17 is located above the screen barrel 19; the screening... A circular plate 18 is rotatably connected to the middle of the barrel 1; the circular plate 18 and the circular rod 16 are rotatably connected; the circular plate 18 is located between the screen barrel 19 and the screening barrel 1; a cleaning rod 102 is fixedly connected to the output end of the cleaning motor 101; the cleaning rod 102 is through-hole and rotatably connected to the screening barrel 1; the surface of the cleaning rod 102 is provided with multiple bristles; during operation, after the transparent plastic masterbatch extruded by the extruder is collected, a batch of transparent plastic masterbatch is poured into the screening barrel 1 through the feed port 13 so that it enters the screen barrel 19, and then the rotary motor 15 and multiple cleaning motors 101 are started, so that they drive the screen barrel 19 and the cleaning rod 102 to rotate, at which time the screen barrel 19 and the cleaning rod 102 rotate in opposite directions. When the sieve barrel 19 rotates, it drives the circular plate 18 to rotate as well, thereby reducing the impact of friction on the rotation of the sieve barrel 19. The rotation of the sieve barrel 19 also drives the internal transparent plastic masterbatch to rotate. During rotation, centrifugal force moves the transparent plastic masterbatch, causing smaller particles to pass through the sieve barrel 19 and come into contact with the screening barrel 1. As the transparent plastic masterbatch moves inside the sieve barrel 19, the smaller particles come into contact with the mesh on the surface of the sieve barrel 19 and pass through the mesh. Simultaneously, the rotation of the cleaning rod 102 drives the bristles to contact the sieve barrel 19. During contact, the bristles extend when they reach the mesh area, causing them to move and dislodge the transparent plastic masterbatch clogged in the mesh. To reduce clogging and allow the remaining transparent plastic masterbatch to exit, after filtration, the cover plate 12 is removed and the mounting plate 17 is rotated to gradually rise away from the surface of the round rod 16. At this time, the sieve barrel 19 can be slid off the round rod 16 to collect and remove small particles. By using the sieve barrel 19 to filter the transparent plastic masterbatch, smaller particles are squeezed out of the sieve barrel 19 by centrifugal force during filtration, while larger particles are intercepted and remain inside the sieve barrel 19. When the sieve barrel 19 comes into contact with the cleaning rod 102, it is also pushed by the bristles on the cleaning rod 102, causing the transparent plastic masterbatch blocking the mesh of the sieve barrel 19 to move, thus unlocking the movement path and increasing the cleaning of the sieve barrel 19.
[0026] like Figures 3 to 5As shown, multiple air-blowing pipes 2 are fixedly connected to the bottom of the screening barrel 1; the ends of the air-blowing pipes 2 are connected to air jet heads 21; the bottom of the air-blowing pipes 2 are connected to connecting pipes 22; during operation, when rotating inside the screening barrel 19, the connecting pipes 22 can be connected to an air pump, and the airflow is transmitted through the connecting pipes 22 into the air-blowing pipes 2, and finally sprayed out from the air jet heads 21, entering from the bottom of the screening barrel 19 and contacting the transparent plastic masterbatch. Upon contact, the transparent plastic masterbatch is blown, causing it to gradually rise and then fall, thereby increasing the movement of the transparent plastic masterbatch inside the screening barrel 19 and increasing its contact with the mesh holes of the screening barrel 19; by adding air jet heads 21, the transparent plastic masterbatch inside the screening barrel 19 can be blown, increasing its movement area inside the screening barrel 19, thereby making it more comprehensive when in contact with the screening barrel 19, increasing its contact with the screening barrel 19 and thus accelerating the separation of the transparent plastic masterbatch.
[0027] like Figures 3 to 4 As shown, a rubber sheet 3 is installed on the top of the jet head 21; the rubber sheet 3 and the jet head 21 are connected by a fixing screw 31; during operation, when the airflow is ejected from the jet head 21, it pushes the rubber sheet 3, and after being pushed, it rotates the rubber sheet 3, causing it to open the jet head 21. After opening, the rubber sheet 3 blocks the transparent plastic masterbatch on both sides, reducing its contact with the top of the jet head 21; by adding the rubber sheet 3, the surrounding transparent plastic masterbatch can be intercepted when the airflow is blown out through the jet head 21, reducing its impact on the airflow ejected from the jet head 21.
[0028] like Figures 2 to 3 As shown, a pair of fixing rods 4 are fixedly connected to the top of the screen barrel 19; a lifting plate 41 is fixedly connected to the top of the fixing rods 4; during operation, when the screen barrel 19 is lifted, it can first contact the lifting plate 41, and then when the screen barrel 19 is lifted, it will be supported at both ends, so that the screen barrel 19 can be lifted more quickly and thus quickly removed; by adding the lifting plate 41, multiple force points can be added when lifting the screen barrel 19, so that it can be quickly raised and left the interior of the screening barrel 1.
[0029] like Figure 5 As shown, a connecting plate 5 is fixedly attached to the surface of the connecting pipe 22; a semiconductor cooler 51 is fixedly attached to the surface of the connecting plate 5; the output end of the semiconductor cooler 51 is located inside the connecting pipe 22; during operation, the semiconductor cooler 51 is turned on before the airflow enters, and then the airflow will contact the output end of the semiconductor cooler 51 when it passes through the connecting pipe 22, thereby cooling the airflow. When the low-temperature airflow comes into contact with the transparent plastic masterbatch, it will reduce the heat generated by friction between them, thereby reducing the heat inside the screening barrel 1. Finally, the airflow will gradually move towards the feed inlet 13 and leave the interior of the screening barrel 1; by adding the semiconductor cooler 51, the airflow can be cooled, and after cooling, the heat generated by friction between the transparent plastic masterbatch can be reduced.
[0030] like Figures 1 to 2 As shown, a clamping plate 6 is provided on the top of the feed inlet 13; the clamping plate 6 and the feed inlet 13 are correspondingly arranged; during operation, when the screening barrel 1 is not in use, the clamping plate 6 can be placed on the top of the feed inlet 13 to close the feed inlet 13. After closing, dust can be reduced from entering the screening barrel 1 from the feed inlet 13; by adding the clamping plate 6, the screening barrel 1 can be closed, which increases its protection when placed.
[0031] Working Principle: After collecting the transparent plastic masterbatch extruded from the extruder, a batch of transparent plastic masterbatch is poured into the screening barrel 1 through the feed inlet 13, allowing it to enter the screen barrel 19. Then, the rotary motor 15 and multiple cleaning motors 101 are started, causing the screen barrel 19 and cleaning rod 102 to rotate. At this time, the screen barrel 19 and cleaning rod 102 rotate in opposite directions. The rotation of the screen barrel 19 drives the circular plate 18 to rotate, thereby reducing the impact of friction on the rotation of the screen barrel 19. The rotation of the screen barrel 19 drives the transparent plastic masterbatch inside to rotate, and during rotation, centrifugal force drives the transparent masterbatch to rotate. The plastic masterbatch moves, and then smaller particles are discharged through the sieve 19 and come into contact with the screening hopper 1. As the transparent plastic masterbatch moves inside the sieve 19 under centrifugal force, the smaller particles come into contact with the mesh on the surface of the sieve 19 and leave through the mesh. Simultaneously, the rotation of the cleaning rod 102 causes the bristles to come into contact with the sieve 19. During this contact, the bristles extend as they move to the mesh area, causing them to dislodge the transparent plastic masterbatch clogging the mesh, thus reducing clogging and making way for the remaining transparent plastic masterbatch. After filtration, the cover plate 12 is removed, and the mounting plate is... Rotate 17 to gradually rise and leave the surface of the round rod 16. At this time, the sieve bucket 19 can be slid off the round rod 16 to collect small particles. When the airflow is ejected from the jet nozzle 21, it pushes the rubber sheet 3. After being pushed, the rubber sheet 3 rotates, causing it to open the jet nozzle 21. After opening, the rubber sheet 3 blocks the transparent plastic masterbatch on both sides, reducing its contact with the top of the jet nozzle 21. When lifting the sieve bucket 19, it first contacts the lifting plate 41. Then, when lifting the sieve bucket 19, it is supported at both ends, which allows the sieve bucket 19 to rise more quickly. Quickly remove the screen barrel 19; turn on the semiconductor cooler 51 before the airflow enters, and then the airflow will contact the output end of the semiconductor cooler 51 when it passes through the connecting pipe 22, thereby cooling the airflow. When the low-temperature airflow comes into contact with the transparent plastic masterbatch, it will reduce the heat generated by friction between them, thereby reducing the heat inside the screen barrel 1. Finally, the airflow will gradually move towards the feed inlet 13 and leave the inside of the screen barrel 1. When the screen barrel 1 is not in use, the card plate 6 can be placed on top of the feed inlet 13 to close the feed inlet 13. After closing, dust can be reduced from entering the inside of the screen barrel 1 from the feed inlet 13.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
