Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, and in particular to a screening machine for biodegradable plastic particles. Background Technology

[0002] Biodegradable plastic pellets are plastic pellets that can be decomposed in the natural environment through biological processes (such as microorganisms, fungi, or plants). They are easier to decompose and reduce environmental pollution. However, since the size, shape, and density of plastic pellets may vary during the production process, screening machines are needed to ensure that the pellets meet the required specifications and size.

[0003] When using a vibrating screen for screening in the production of biodegradable plastic granules, the vibrating screen is first started, causing the vibrating motor to drive the screen to vibrate. Then, the material is poured out from the feed hopper and falls onto the screen mesh. It then slides off the screen surface due to vibration. Particles of different sizes slide on different layers of the screen mesh until they are discharged and collected from the outlet on one side. However, in actual use, it has been found that when a large amount of plastic granules are poured onto the top layer of the screen mesh, material accumulation occurs, making it difficult to fully utilize the screen mesh and reducing the screening effect and working efficiency of the vibrating screen. Utility Model Content

[0006] The effect achieved by the above components is as follows: when biodegradable plastic granules are produced and screened, the vibrating screen is first started, and the vibrating motor drives the vibrating screen to operate and vibrate. Then, the material is poured out from the feed hopper and falls onto the screen of the vibrating screen. With the assistance of the auxiliary device, it is spread on the screen. Finally, material granules of different sizes will be discharged and collected from the discharge port on one side of the screen of different sizes.

[0007] Preferably, the auxiliary device includes two mounting plates, which are respectively disposed on both sides of the surface of the vibrating screen.

[0011] Preferably, the auxiliary device further includes two stabilizing plates fixedly connected to the surface of the mounting plate, wherein the two sides of the surface of the stabilizing plates are slidably connected to the inner wall of the connecting strip.

[0012] The effect achieved by the above components is that, by setting up the stabilizing plate, the connecting belt on the pulley is less likely to loosen or shift during use, thus ensuring the normal operation of the device.

[0013] Preferably, the auxiliary device further includes a protective sleeve fitted onto the output end of the servo motor, wherein the protective sleeve is fixedly connected to the surface of the mounting plate.

[0014] The effect achieved by the above components is that, through the protective cover made of rubber material, it is not easy for foreign objects to enter the output end of the servo motor during use, thus ensuring the normal operation of the servo motor.

[0015] Preferably, a connecting device is provided on both sides of the surface of the vibrating screen. The connecting device includes two fixed frames, which are fixedly connected to both sides of the surface of the vibrating screen. A connecting rod is inserted into the inner wall of each of the two fixed frames.

[0016] The effect achieved by the above components is to install and fix the connecting rod and the components on the surface, thereby making the auxiliary device more convenient and faster to use, and also facilitating subsequent inspection and maintenance.

[0017] Preferably, an operating block is fixedly connected to the surface of the bolt, wherein the operating block assists in the rotation of the bolt.

[0018] The effect achieved by the above components is that the operation block makes it easier and faster to rotate the bolt during use, thereby making the disassembly and assembly of the auxiliary device more convenient and quick, and improving the ease of use of the auxiliary device.

[0019] Preferably, the connecting device further includes a washer fitted onto the arc surface of the bolt, wherein the washer enhances the performance of the bolt.

[0020] The effect achieved by the above components is that, by setting the washers, when the bolts are installed through the surface of the fixing frame, they can fit more stably and are less likely to have gaps, thus ensuring the stable installation of the connecting rod.

[0031] Figure 1 and Figure 2 The biodegradable plastic pellet screening machine shown includes a vibrating screen 1, a feed hopper 4 fixedly connected to the surface of the vibrating screen 1, a vibrating motor 5 installed at the bottom of the vibrating screen 1, several discharge ports 6 opened on one side of the vibrating screen 1, an auxiliary device 2 provided on the surface of the vibrating screen 1, wherein the auxiliary device 2 uses rollers 23 and auxiliary plates 24 to spread and screen the material output from the feed hopper 4, and connecting devices 3 are respectively provided on both sides of the surface of the vibrating screen 1.

[0032] Figure 1 , Figure 2 and Figure 3The auxiliary device 2 shown includes two mounting plates 21, which are respectively disposed on both sides of the surface of the vibrating screen 1. Two rotating rods 22 are rotatably mounted on the two mounting plates 21. Several evenly distributed rollers 23 are fixedly connected to the arc surface of one rotating rod 22, and several auxiliary plates 24 are fixedly connected to the arc surface of the other rotating rod 22. Several grooves are formed on the surface of each auxiliary plate 24. Belts are fixedly connected to the arc surfaces of one end of each of the two rotating rods 22, and the two belts are connected and fixed by a connecting belt 26. A servo motor 27 is mounted on the surface of one of the mounting plates 21. The output end of the servo motor 27 is connected to one of the rotating rods 22 via a coupling. When screening biodegradable plastic granules, the vibrating screen 1 is first started, causing the vibrating motor 5 to drive the vibrating screen 1 to vibrate. Then, the material is poured out from the feed hopper 4 and falls onto the screen of the vibrating screen 1. Then, the servo motor 27 on the mounting plate 21 is started. Because the two rotating rods 22 on the mounting plate 21 are connected by the pulley 25 and the connecting belt 26, the two rotating rods 22 will rotate under the drive of the servo motor 27. At this time, the material on the screen of the vibrating screen 1 will be separated by several rollers 23 on the rotating rods 22, so that it moves and rotates more comprehensively on the screen. At the same time, the auxiliary plate 24 on the other rotating rod 22 will move the plastic particles, so that the material can be separated laterally, so that the material is more evenly distributed on the screen of the vibrating screen 1. Finally, material particles of different specifications will be discharged and collected from the discharge port 6 on one side of the screen of different specifications. When using the vibrating screen 1 to screen material particles, the screened material particles will be more evenly distributed on the screen, and it is not easy to accumulate, making the screening of the vibrating screen 1 more efficient and improving the screening efficiency.

[0033] Figure 1 , Figure 2 and Figure 3The auxiliary device 2 shown also includes protective plates 29 installed on the surfaces of the two mounting plates 21. The protective plates 29 provide a certain degree of shielding and protection for the material on the surface of the vibrating screen 1. By setting the protective plates 29, the material on the surface of the vibrating screen 1, which is combed and spread by the rollers 23 and the auxiliary plates 24, is less likely to splash when moving. It can be effectively shielded by the protective plates 29, ensuring the stable screening of plastic particles. The auxiliary device 2 also includes two stabilizing plates 28 fixedly connected to the surface of the mounting plates 21. The two sides of the surface of the stabilizing plates 28 are slidably connected to the inner wall of the connecting belt 26. By setting the stabilizing plates 28, the connecting belt 26 on the pulley 25 is less likely to loosen or shift during use, ensuring the normal operation of the device. The auxiliary device 2 also includes a protective sleeve 210 sleeved on the output end of the servo motor 27. The protective sleeve 210 is fixedly connected to the surface of the mounting plates 21. By setting the protective sleeve 210, the output end of the servo motor 27 is less likely to be invaded by foreign objects during use, ensuring the normal operation of the servo motor 27.

[0034] Figure 1 , Figure 2 and Figure 4 The connecting device 3 shown includes two fixed frames 32, which are fixedly connected to both sides of the surface of the vibrating screen 1. Connecting rods 31 are inserted into the inner walls of the two fixed frames 32 respectively. The connecting rods 31 are fixedly connected to the surface of the mounting plate 21. The connecting rods 31 and the fixed frames 32 are connected and fixed by bolts 33. When installing and fixing the auxiliary device 2, the connecting rods 31 fixedly connected to the surface of the two mounting plates 21 are first inserted into the inner walls of the fixed frames 32 fixedly connected to both sides of the surface of the vibrating screen 1. Then, the bolts 33 are passed through the surface of the fixed frames 32 until the bolts 33 are threadedly connected to the surface of the connecting rods 31, thereby installing and fixing the connecting rods 31 and the components on the surface. This makes the auxiliary device 2 more convenient and faster to use, and also facilitates subsequent inspection and maintenance.

[0035] Figure 1 and Figure 4 An operating block 34 is fixedly connected to the surface of the bolt 33 shown. The operating block 34 assists in the rotation of the bolt 33. The operation block 34 makes it easier and faster to rotate the bolt 33 during use, making the disassembly and assembly of the auxiliary device 2 more convenient and quick, and improving the ease of use of the auxiliary device 2. The connecting device 3 also includes a washer 35 fitted on the arc surface of the bolt 33. The washer 35 enhances the performance of the bolt 33. The washer 35 ensures that when the bolt 33 is installed through the surface of the fixed frame 32, it can fit more stably and securely, without gaps, thus ensuring the stable installation of the connecting rod 31.

[0036] Working principle: When screening biodegradable plastic granules, the vibrating screen 1 is first started, causing the vibrating motor 5 to drive the vibrating screen 1 to vibrate. The material is then poured out from the feed hopper 4 and falls onto the screen of the vibrating screen 1. Next, the servo motor 27 on the mounting plate 21 is started. Because the two rotating rods 22 on the mounting plate 21 are connected by pulleys 25 and a connecting belt 26, the two rotating rods 22 rotate under the drive of the servo motor 27. At this time, the material on the screen of the vibrating screen 1 is separated by several rollers 23 on the rotating rods 22. This allows for more comprehensive movement and swirl of the screen mesh. Simultaneously, the auxiliary plate 24 on another rotating rod 22 agitates the plastic granules, enabling lateral separation of the material. This results in a more even distribution of the material on the screen mesh of the vibrating screen 1. Finally, material granules of different specifications are discharged and collected from the discharge port 6 on one side of the screen mesh of different specifications. When using the vibrating screen 1 to screen material granules, the screened material granules are more evenly distributed on the screen mesh, preventing accumulation and making the screening of the vibrating screen 1 more efficient, thus improving the screening work efficiency.

[0037] When installing and fixing the auxiliary device 2, first insert the connecting rods 31 that are fixedly connected to the surfaces of the two mounting plates 21 into the inner walls of the fixing frames 32 that are fixedly connected to both sides of the surface of the vibrating screen 1. Then, the bolts 33 are passed through the surface of the fixing frames 32 until the bolts 33 are threadedly connected to the surface of the connecting rods 31, thereby installing and fixing the connecting rods 31 and the components on the surface. This makes the auxiliary device 2 more convenient and faster to use, and also facilitates subsequent inspection and maintenance.
