Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment, and in particular to a high-efficiency screening device for modified plastics. Background Technology

[0002] In the plastics processing industry, modified plastics are widely used in many fields such as electronics, automobile manufacturing, aerospace, and building materials due to their excellent comprehensive properties, such as high strength, high toughness, and corrosion resistance.

[0003] Existing plastic screening devices generally suffer from technical bottlenecks such as low automation and insufficient feeding efficiency. They rely on manual operation for small-batch, multiple feeding operations, which is difficult to match the high-efficiency requirements of continuous industrial production. This leads to frequent interruptions in the screening process, significantly reducing overall production efficiency and causing problems such as uneven feeding and fluctuations in feeding volume. It may also cause local screen overload and blockage, further exacerbating the low screening efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of low feeding efficiency in plastic screening devices, the technical problem of this utility model is to provide a modified plastic high-efficiency screening device.

[0005] The technical solution of this utility model is: a high-efficiency screening device for modified plastics, including a base, a screening machine fixedly connected to the left side of the base, a bracket fixedly connected to the right side of the base, a material cylinder fixedly connected to the bracket by bolts, the material cylinder being installed at an angle with the left side higher than the right, a discharge port located downwards on the left side of the material cylinder, the discharge port being directly above the screening machine to ensure that the material can accurately fall into the screening machine, a feed port located upwards on the right side of the material cylinder, an auger rotatably connected inside the material cylinder, a motor fixedly connected to the right side of the bracket, the output shaft of the motor passing through the right side of the material cylinder and fixedly connected to the right side of the auger by a coupling, a feed hopper fixedly connected to the top right side of the bracket by welding, and the outlet of the feed hopper being fixedly connected to the upper part of the feed port of the material cylinder by a flange.

[0006] Preferably, the feed hopper also includes a cover plate, with the top of the feed hopper symmetrically connected to the cover plate via hinges, the front side of the rear cover plate being fixedly connected to a buckle, and handles being fixedly connected to both cover plates.

[0007] Preferably, a splash guard is also included, which is fixedly connected to the screening machine by bolts.

[0008] Preferably, the bracket also includes a hook, which is fixedly connected to the bracket by welding.

[0009] Preferably, the system also includes lighting fixtures, which are arranged in a ring on the splash guard.

[0010] Preferably, the base also includes a push rod, which is fixedly connected to the base by bolts.

[0011] The beneficial effects are as follows: By combining the auger and the inclined cylinder, a highly efficient material conveying system is formed. The spiral blades of the auger rotate at high speed under the drive of the motor. Combined with the inclined structure of the cylinder, which is higher on the left and lower on the right, the material can be pushed from the feed port to the discharge port quickly and stably by utilizing the dual effects of gravity and mechanical thrust. Compared with traditional devices, the feeding efficiency is significantly improved.

[0012] The feed hopper is equipped with a cover plate, buckles, and handles to form a tight protection system. The cover plate can completely cover the feed inlet, the buckles can firmly fasten the cover plate to prevent material from overflowing during the conveying process, and the handles make it easy for operators to open and close. The combination of the three not only reduces dust, but also prevents material waste, improves the working environment, and enhances the environmental friendliness and safety of production.

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] Example: A high-efficiency screening device for modified plastics, such as Figure 1-4As shown, the system includes a base 1, a screening machine 2, a support 3, a material cylinder 4, a motor 5, an auger 6, a feed hopper 7, and a discharge port 8. The screening machine 2 is fixedly connected to the left side of the base 1, and the support 3 is fixedly connected to the right side of the base 1. The material cylinder 4 is fixedly connected to the support 3 by bolts. The material cylinder 4 is installed at an angle with the left side higher than the right side. The discharge port 8 is located on the downward-facing left side of the material cylinder 4 and is located directly above the screening machine 2 to ensure that the material can accurately fall into the screening machine 2. The feed port is located on the upward-facing right side of the material cylinder 4. The auger 6 is rotatably connected inside the material cylinder 4. The motor 5 is fixedly connected to the right side of the support 3. The output shaft of the motor 5 passes through the right side of the material cylinder 4 and is fixedly connected to the right side of the auger 6 by a coupling. The feed hopper 7 is fixedly connected to the top right side of the support 3 by welding. The outlet of the feed hopper 7 is fixedly connected to the upper part of the feed port of the material cylinder 4 by a flange. It also includes a cover plate 9, a buckle 10, and a handle 11. The top of the feed hopper 7 is symmetrically connected to the cover plate 9 via hinges. The buckle 10 is fixedly connected to the front side of the rear cover plate 9. The handle 11 is fixedly connected to both cover plates 9. It also includes a splash guard 12, which is fixedly connected to the screening machine 2 by bolts. It also includes a hook 13, which is fixedly connected to the bracket 3 by welding. It also includes lighting lamps 14, which are arranged in a ring on the splash guard 12. It also includes a push rod 15, which is fixedly connected to the base 1 by bolts.

[0020] The motor 5 is started, and its output shaft drives the auger 6 inside the material cylinder 4 to rotate via a coupling. At this time, the operator opens the cover plate 9 on top of the feed hopper 7 using the handle 11, pouring the modified plastic raw material to be screened into the feed hopper 7. The outlet of the feed hopper 7 is tightly connected to the feed inlet of the material cylinder 4 via a flange, ensuring smooth material entry into the material cylinder 4. After feeding is complete, the operator uses the buckle 10 to fasten the cover plate 9 to prevent material overflow or dust generation during conveying. The motor 5 drives the auger 6 to rotate at high speed, using the spiral blades of the auger 6 to convey the modified plastic from the feed inlet on the right side of the material cylinder 4 to the discharge outlet 8 on the left side. Because the material cylinder 4 is installed at an angle, higher on the left and lower on the right, the material moves rapidly towards the discharge outlet 8 under the combined action of gravity and the thrust of the auger 6. The discharge outlet 8 is located directly above the screening machine 2, and the material falls into the screening machine 2 from the discharge outlet 8. After the screening machine 2 is started, its internal structure begins to work, classifying and screening the materials. The splash guard 12 is installed on the screening machine 2 to effectively prevent material from splashing during screening, ensuring a clean working environment. The lighting 14, arranged in a ring on the splash guard 12, is turned on simultaneously, providing operators with a clear working view for easy observation of the screening process. During screening, operators can hang tools on the hooks 13 on the support 3 for easy access, improving work efficiency. After the modified plastic screening is complete, the operator first turns off the screening machine 2, then turns off the motor 5, stopping the rotation of the auger 6. Then, the cover plate 9 of the feed hopper 7 is opened to clean any remaining material inside, preventing material clumping and affecting future use. Simultaneously, the screens inside the screening machine 2 are checked for blockages or damage; if necessary, they should be cleaned or replaced promptly. After prolonged use, operators can periodically inspect and tighten the bolt connections between the material cylinder 4 and the support 3, as well as the coupling connection between the motor 5 and the auger 6, to ensure the stability and reliability of the equipment. Furthermore, rotating components such as the auger 6 and the screening mechanism 2 can be lubricated and maintained to extend the equipment's service life. Throughout the operation, the push rod 15 facilitates easy movement of the equipment by the operator when needed, improving its flexibility and applicability.
