Description

Technical Field

[0001] This utility model relates to the technical field of plastic masterbatch production equipment, specifically an air-cooled vibrating screen for plastic masterbatch production. Background Technology

[0002] As a key raw material in the plastics processing industry, the quality of plastic masterbatch directly affects the performance of the final plastic products. Whether it is mechanical properties, appearance quality, or performance in use, all are closely related to the quality of the masterbatch. In the production process of plastic masterbatch, screening is a crucial step. It can not only effectively remove impurities mixed in during the production process, such as metal scraps and dust, but also accurately separate masterbatch of different particle sizes, thereby ensuring the uniformity and consistency of the masterbatch and providing high-quality raw materials for subsequent plastic processing steps such as injection molding and extrusion. Vibrating screens, as the core equipment for realizing this screening process, are widely used in the production of plastic masterbatch.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN215882218U) discloses a vibrating screen for plastic masterbatch production, comprising a screening device body, a vibrating screen, and a power mechanism. A feed funnel is located at the top of the screening device body, connecting to the internal screening chamber. The vibrating screen is installed within the screening chamber, and a vibrating arc-shaped block is fixed to the edge of the vibrating screen. This vibrating arc-shaped block protrudes from the side wall of the screening device body and frictionally connects with the power mechanism. The power mechanism includes a motor, a rotating disk, a rotating arm, and a friction roller shaft. The motor sits on an "L"-shaped mounting base fixed to the bottom of the screening device body and is connected to the rotating disk via shaft transmission. A drive column is fixed to the upper edge of the rotating disk, inserting into a long, narrow slot in the middle of the rotating arm and movably connecting to it. One end of the rotating arm is rotatably mounted on the bottom wall of the screening device body via a rotating shaft, and the other end is fixed to the friction roller shaft, which frictionally contacts the vibrating arc-shaped block.

[0004] Although the aforementioned patent can drive the vibrating screen to perform vibrating screening operations through the setting of vibrating arc blocks and power mechanisms, thereby improving the filtration quality and operating efficiency of the device, the temperature of the newly produced masterbatch is relatively high. However, the existing equipment lacks a targeted cooling design and relies solely on natural cooling and heat dissipation. As a result, the masterbatch is prone to remain sticky due to the high temperature during the screening process, and thus easily sticks together to form clumps. These clumps not only easily block the screen holes and cause congestion in the screening channel, but also cause unqualified sticky particles to be mixed into the final product, seriously affecting the screening efficiency and the purity of the masterbatch.

[0005] Therefore, this utility model provides an air-cooled vibrating screen for producing plastic masterbatch to solve the above problems. Utility Model Content

[0017] 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 protection scope of the present utility model.

[0018] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide an air-cooled vibrating screen for producing plastic masterbatch, including a shell 1, a screening component is provided inside the shell 1, and two mounting shells 2 are symmetrically fixedly connected to the screening component on the inner wall of the shell 1, and an air-cooling component is provided on the inner side of each of the two mounting shells 2. The air-cooled assembly includes a filter plate 301 fixedly connected to the inner side of the mounting housing 2. The inner wall of the filter plate 301 is rotatably connected to a rotating column 302. The top of the rotating column 302 is fixedly connected to a connecting transmission wheel A303, and the bottom of the rotating column 302 is fixedly connected to a fan 304. The upper surface of the outer casing 1 is fixedly connected to a fixed base 401 and two support blocks 402. The fixed base 401 is fixedly connected to the inner side of the fixed base 401. The ends of the two output shafts of the dual-axis motor 403 are fixedly connected to rotating rods 404, and the outer walls of the two rotating rods 404 are rotatably connected to the inner walls of the two support blocks 402 respectively. One end of the rotating rods 404 is fixedly connected to a transmission wheel B405, and the outer edges of the two transmission wheels B405 mesh with the outer edges of the two transmission wheels A303 respectively.

[0019] In this embodiment, by starting the dual-axis motor 403, the dual-axis motor 403 will drive the two rotating rods 404 and the transmission wheels B fixedly connected to the ends of the rotating rods 404 to rotate synchronously through the two output shafts. The transmission wheels B405 at one end of the two rotating rods 404 are respectively meshed with the transmission wheels A303 at the top of the two rotating columns 302. When the two transmission wheels B405 rotate, they will drive the two transmission wheels A303 to rotate. During the rotation of the transmission wheels A, they will drive the fan 304 fixedly connected to the bottom of the rotating column 302 to rotate through the rotating column 302. When the fan 304 rotates, it will generate airflow. After the airflow is filtered by the filter plate 301, it will be blown out through the inside of the mounting shell 2 into the screen frame 104, thereby cooling the plastic masterbatch in the screen frame 104. This effectively prevents the plastic masterbatch from sticking together due to the high temperature of the masterbatch itself during the screening process.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, multiple hinges 201 are symmetrically fixedly connected to the bottom opening of the mounting shell 2, and a guide plate 202 is hinged between the ends of every two hinges 201. Two limiting grooves 203 are opened on the inner side of the mounting shell 2, and an L-shaped connecting plate 204 is slidably connected to the inner side of the limiting groove 203. Multiple movable grooves A205 are opened on the outer wall of the L-shaped connecting plate 204, and the inner side of the multiple movable grooves A205 is slidably adapted to the end protrusions of the multiple guide plates 202 respectively. U-shaped frames 501 are slidably connected to the inner walls of both mounting shells 2. Both ends of the U-shaped frames 501 are fixedly connected to one side of two L-shaped connecting plates 204. A connecting frame 502 is fixedly connected between one side of the two U-shaped frames 501. A movable groove B503 is opened on the outer wall of the connecting frame 502. A mounting frame 504 is fixedly connected to the top surface inside the shell 1 above the movable groove B503. A drive motor A505 is fixedly connected to the inner side of the mounting frame 504. An adjusting plate A506 is fixedly connected to the end of the output shaft of the drive motor A505. The outer side of the protrusion at one end of the adjusting plate A506 is slidably adapted to the inner side of the movable groove B503.

[0021] In this embodiment, when the airflow generated by the fan 304 rotates cools the plastic masterbatch inside the screen frame 104, the drive motor A505 is started. Upon startup, the drive motor A505 drives the adjusting plate A, which is fixedly connected to its output shaft, to rotate. Since the outer side of the protrusion at one end of the adjusting plate A506 slides into the movable groove B503 of the connecting frame 502, the protrusion of the adjusting plate A slides along the inner side of the movable groove B503 during the rotation of the adjusting plate A506. This pushes the connecting frame 502 and the U-shaped frame 501 fixedly connected to both ends of the connecting frame 502 to reciprocate. Simultaneously, the reciprocating movement of the U-shaped frame 501 pushes the L-shaped connecting frame 502 fixedly connected to its end to move synchronously along the inner side of the limiting groove 203. During the movement of the L-shaped connecting plate, due to the L... The movable groove A205 on the L-shaped connecting plate 204 is slidably adapted to the protrusion at the end of the air guide plate 202, so that when the L-shaped connecting plate 204 slides, it drives the air guide plate 202 to reciprocate around the end of the hinge 201. Then, the direction of the airflow is cyclically adjusted by the reciprocating air guide plate 202, so that the cold air can be blown more accurately to the masterbatch in the screen frame 104, and the airflow can cool the plastic masterbatch.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the screening assembly includes two fixed frames 101 fixedly connected to the inner side of the outer shell 1. The inner side of each fixed frame 101 is fixedly connected to a limiting post 102. The outer wall of each limiting post 102 is slidably connected to a slide block 103. A screen frame 104 is fixedly connected between the outer sides of every two slide blocks 103. A T-shaped frame 105 is fixedly connected to one side of the screen frame 104. An movable groove C106 is opened on the outer side of the T-shaped frame 105.

[0023] The screening assembly also includes a support plate 107 fixedly connected to the inside of the housing 1. A drive motor B108 is fixedly connected to the upper surface of the support plate 107. An adjustment plate B109 is fixedly connected to the end of the output shaft of the drive motor B108. The outer side of the protrusion at one end of the adjustment plate B109 is slidably adapted to the inner side of the movable groove C106.

[0024] In this embodiment, when the plastic masterbatch falls into the screen frame 104 through the guide of the feed hopper, the drive motor B108 is started. After the drive motor B108 is started, it will drive the adjusting plate B109, which is fixedly connected to its output shaft, to rotate. During the rotation, the adjusting plate B109 slides and adapts to the movable groove C106 of the T-shaped frame 105 through the outer side of its protrusion. Thus, the rotation of the adjusting plate B109 can drive the T-shaped frame 105 to apply force to the screen frame 104, so that the screen frame 104 can reciprocate along the outer side of the limiting post 102 through the two sliding blocks 103. Then, under the reciprocating movement of the screen frame 104, the plastic masterbatch inside the screen frame 104 will shake continuously. During the sliding process, the plastic masterbatch can be screened through the through hole of the screen frame 104.

[0025] In this embodiment, as Figure 2 As shown, a feeding hopper 6 is fixedly connected to the inner wall of the outer shell 1, and the bottom opening of the feeding hopper 6 corresponds to the top opening of the screen frame 104.

[0026] A receiving box 7 is provided on the bottom surface inside the outer casing 1, and a handle 701 is fixedly connected to one side of the receiving box 7.

[0027] In this embodiment, the top opening of the hopper 6 is a cone-shaped open design to facilitate the feeding of masterbatch. After the masterbatch enters the hopper 6, it will fall from the bottom opening of the hopper 6 into the screen frame 104 for screening under the guidance of the hopper 6. The screened masterbatch will fall into the receiving box 7 below the screen frame 104. Then the receiving box 7 can be removed by the handle 701 to collect the screened masterbatch.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
