Description

Technical Field

[0001] This utility model belongs to the field of vibrating screen technology, and in particular relates to a plastic fragment vibrating screen with a quick screen replacement function. Background Technology

[0002] With the booming development of the plastic products industry, the plastic recycling industry has become increasingly important. In the process of plastic recycling, the screening of plastic fragments is one of the key links. By using a vibrating screen to accurately screen plastic fragments, plastic fragments of different sizes can be separated so that they can be processed into plastic products that meet different needs.

[0003] However, existing plastic fragment vibrating screens are inconvenient to replace when in use, requiring a lot of time to disassemble and install the screens, resulting in long downtime of the equipment. This can seriously affect the overall production schedule when plastic recycling companies need to frequently adjust the particle size of plastic particles. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic fragment vibrating screen with a quick screen replacement mechanism. By setting up a snap-fit ​​mechanism, it solves the problem that existing plastic fragment vibrating screens are inconvenient to replace during use, requiring a lot of time to disassemble and install the screen, resulting in long-term equipment downtime. This is especially problematic when plastic recycling companies need to frequently adjust the particle size of plastic particles, which seriously affects the overall production progress.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a plastic fragment vibrating screen with a quick-change screen, including a base plate, on which a plurality of snap-fit ​​mechanisms and a vibration mechanism are provided;

[0007] A support frame one is provided above the base plate. A support frame two is fixedly connected to the inner wall of the support frame one. A filter plate is slidably connected between the support frame one and the support frame two. The buckling mechanism includes a limiting pin that passes through the support frame two. The limiting pin is slidably connected to the support frame two. The bottom of the limiting pin passes through the support frame one and the filter plate. The limiting pin is slidably connected to the support frame one and the filter plate. Two limiting grooves are provided on the limiting pin. A rectangular box is fixedly connected to the bottom of the support frame one. Two fixing blocks are fixedly connected to the bottom of the support frame one. The vibration mechanism includes a motor frame fixedly connected to the top of the base plate.

[0008] Furthermore, telescopic rods are fixedly connected to the sides of the two fixed blocks that are close to each other, and limit blocks are fixedly connected to the sides of the two telescopic rods that are close to each other. The two limit blocks are respectively adapted to the two limit grooves.

[0009] Furthermore, the outer wall of the telescopic rod is fitted with a spring, and the sides of the two springs that are close to each other are fixedly connected to two limiting blocks, and the sides of the two springs that are far from each other are fixedly connected to two fixing blocks. The outer wall of the rectangular box has two sliding grooves, and the inner walls of the two sliding grooves are slidably connected with sliding rods. The back sides of the two sliding rods are slidably connected to the two limiting blocks, and the outer wall of the support frame is hinged with a number of hinge rods.

[0010] Furthermore, the vibration mechanism includes a dual-axis motor fixedly connected to the inner wall of the motor frame. The two output shafts of the dual-axis motor are fixedly connected to a rotating shaft 1 via a coupling. The outer walls of the two rotating shafts 1 are rotatably connected to a support block 1. The bottoms of the two support blocks 1 are fixedly connected to a base plate. Turntables are fixedly connected to the sides of the two rotating shafts 1 that are far apart from each other.

[0011] Furthermore, each of the two turntables is fixedly connected to a hinge shaft on the side away from the motor frame. Two hinge rods are rotatably connected to the outer walls of the two hinge shafts. A rotating shaft passes through each of the two hinge rods. A support block is rotatably connected to the outer wall of the rotating shaft. The top of the support block is fixedly connected to the support frame.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a snap-fit ​​mechanism, when the filter plate needs to be replaced, slide the two sliding rods so that they move away from each other under the limit of the sliding groove. This causes the two limit blocks to move away from each other, and the two limit blocks squeeze the two telescopic rods and springs respectively, causing them to retract. Once the two limit blocks separate from the two limit grooves, the limit pins can be pulled out, releasing the two sliding rods. The two springs will then drive the two limit blocks to reset. Similarly, pull out the other limit pins to pull the filter plate out from between support frame one and support frame two. Insert the new filter plate between the bottom plate 1 and support frame two, and then insert the limit pins. The holes on the second support frame allow it to slide into the rectangular box, where it will press against two limiting blocks. These blocks will then press against two telescopic rods and springs, causing them to contract. Once the two limiting blocks have slid into the two limiting slots, the two springs will drive them to reset and lock into the slots. Similarly, inserting several other limiting pins completes the quick disassembly of the filter plate. This allows for easy disassembly and installation of the filter plate. In plastic recycling and plastic product manufacturing, filter plates of different mesh sizes can be promptly replaced to adapt to the varying characteristics of different batches of plastic fragments, ensuring efficient operation of the production line.

[0014] 2. After placing the plastic to be screened on the filter plate by setting up a vibration mechanism, turn on the dual-axis motor on the motor frame. The dual-axis motor is a device that uses electromagnetic principles to achieve output motion. It consists of a set of permanent magnets and two magnetic shafts. Its working principle is that when current passes through the motor, two sets of magnetic fields are generated in the permanent magnets. The magnets on each magnetic shaft face opposite directions. These magnetic forces work together to give the motor rotational power, forming a continuous and stable rotational output. The dual-axis motor drives the two rotating shafts to rotate through the output shaft. The two rotating shafts drive the two turntables to rotate respectively. Two hinge shafts are driven to rotate around the first pivot shaft in a circular motion. These two hinge shafts, in turn, drive the second pivot shaft via two hinge rods. The second pivot shaft, through the second support block, causes the first support frame to vibrate, which in turn causes the filter plate on it to vibrate. At the same time, the four hinge rods are also driven by the first support frame to rotate at a small angle in a circular motion, thus ensuring the continuous vibration of the first support frame. This allows the screen to shake rapidly and frequently, causing plastic fragments to contact the screen mesh more quickly. This enables the vibrating screen to process more plastic fragments per unit time, significantly improving the overall screening efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Sliding connection: The bottom of the limiting pin 211 passes through the support frame 111 and the filter plate 113, and the limiting pin 211, the support frame 111, and the filter plate 113 are slidably connected.

The vibration mechanism 3 includes a motor frame 311 fixedly connected to the top of the base plate 1, and the two fixing blocks 214 are close to each other on one side. Each of the two telescopic rods 215 is fixedly connected to a telescopic rod 215. A limiting block 216 is fixedly connected to the side of each telescopic rod 215 that is close to each other. The two limiting blocks 216 are respectively adapted to two limiting grooves 212. A spring 217 is sleeved on the outer wall of the telescopic rod 215. The side of each spring 217 that is close to each other is fixedly connected to the two limiting blocks 216, and the side of each spring 217 that is far from each other is fixedly connected to two fixing blocks 214. Two sliding grooves 218 are opened on the outer wall of the rectangular box 213. Sliding rods 219 are slidably connected to the inner walls of the two sliding grooves 218. The backs of the two sliding rods 219 are slidably connected to the two limiting blocks 216. Several hinge rods 114 are hinged to the outer wall of the support frame 111. By setting a buckle mechanism 2, the filter plate 113 can be easily disassembled and installed. In plastic recycling and plastic product production, filter plates 113 of different mesh sizes can be replaced in a timely manner according to the different characteristics of different batches of plastic fragments, thereby ensuring the efficient operation of the production line.

[0027] A dual-shaft motor 312 is fixedly connected to the inner wall of the motor frame 311. The two output shafts of the dual-shaft motor 312 are both fixedly connected to rotating shafts 313 via couplings. Support blocks 314 are rotatably connected to the outer walls of both rotating shafts 313. The bottoms of both support blocks 314 are fixedly connected to the base plate 1. Turntables 315 are fixedly connected to the sides of the two rotating shafts 313 that are furthest from each other. Hinges 316 are fixedly connected to the sides of the two turntables 315 that are furthest from the motor frame 311. Two hinge rods 317 are rotatably connected to the outer wall of the 6. A rotating shaft 318 passes through each of the two hinge rods 317. A support block 319 is rotatably connected to the outer wall of the rotating shaft 318.

By setting the vibration mechanism 3, the screen can be made to shake rapidly and frequently, thereby prompting plastic fragments to contact the screen mesh more quickly. This allows the vibrating screen to process more plastic fragments per unit time, significantly improving the overall screening efficiency.

[0028] A specific application of this embodiment is as follows: When the filter plate 113 needs to be replaced, slide the two slide rods 219 so that they move away from each other under the limit of the slide groove 218, thereby causing the two limiting blocks 216 to move away from each other. The two limiting blocks 216 respectively squeeze the two telescopic rods 215 and the spring 217, causing them to retract. After the two limiting blocks 216 separate from the two limiting grooves 212, the limiting pins 211 can be pulled out, and the two slide rods 219 can be released. The two springs 217 will drive the two limiting blocks 216 to reset. Similarly, pulling out the other limiting pins 211 will allow the filter plate to be pulled out. The filter plate 113 slides out from between the first support frame 111 and the second support frame 112. A new filter plate is inserted between the base plate 1 and the second support frame 112. Then, the limiting pin 211 is inserted into the hole on the second support frame 112. After the second support frame 112 slides into the rectangular box 213, it will press against the two limiting blocks 216, causing the two limiting blocks 216 to press against the two telescopic rods 215 and the spring 217, causing them to contract. After the two limiting blocks 216 slide into the two limiting grooves 212 respectively, the two springs 217 will respectively drive the two limiting blocks 216 to reset and lock into the two limiting grooves 212. Similarly, several other limiting pins are inserted. 211, that is, to complete the quick disassembly of filter plate 113, place the plastic to be screened on filter plate 113, and then turn on the dual-shaft motor 312 on motor frame 311. The dual-shaft motor 312 is a device that uses electromagnetic principles to achieve output motion. It consists of a set of permanent magnets and two magnetic shafts. Its working principle is that when current passes through the motor, two sets of magnetic fields are generated in the permanent magnets. The magnets on each magnetic shaft face opposite directions. These magnetic forces work together to give the motor rotational power, forming a continuous and stable rotational output. The dual-shaft motor 312 drives the two rotating shafts 313 through the output shaft. The rotation of the two rotating shafts 313 drives the two turntables 315 to rotate, and the two turntables 315 drive the two hinge shafts 316 to move in a circle around the rotating shaft 313. As a result, the two hinge shafts 316 drive the two hinge rods 317 to drive the rotating shaft 318 to move. The rotating shaft 318 drives the support frame 111 to vibrate through the support block 319, which in turn drives the filter plate 113 on it to vibrate. At this time, the four hinge rods 114 are also driven by the support frame 111 to rotate in a small angle, thus ensuring the continuous vibration of the support frame 111.
