Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically an anti-clogging plastic pellet feeding machine. Background Technology

[0002] In the plastics processing industry, plastic pellet feeders are an indispensable piece of equipment, and their performance directly affects production efficiency and product quality.

[0003] Traditional anti-clogging plastic pellet feeders are equipped with multiple filters to remove dust, but in practice, these filters become difficult to maintain. Especially since they are located inside the feeder, replacing or cleaning them is quite troublesome and requires stopping the machine, which not only interrupts the production process but also wastes a lot of time and manpower.

[0004] Furthermore, existing technologies cannot effectively solve the problem of dust residue inside the hopper during the material intake process. The material particles inside the hopper tend to accumulate and remain essentially stationary until a certain amount is drawn in, at which point they are discharged. Dust trapped between the particles is difficult to remove completely. As production continues, dust accumulates, affecting not only the purity of the plastic particles but also potentially accelerating the wear and tear on equipment components. Utility Model Content

[0026] A square rod is fixed to one end of a rack, and a round block is fixedly connected to one end of the square rod. The round block is slidably inserted into a sliding hole.

[0027] Square rod two is fixed between two round blocks, and square rod two is slidably inserted into the sliding groove;

[0028] The multi-stage pipe is provided in one set, with the sliding pipe fixed on the second square rod and the insertion pipe fixed on the outer wall of the bellows.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] 1. The electric push rod drives the rack and pinion to mesh with the gear ring, causing the hopper to swing back and forth, which in turn causes the raw material to sway. During the movement, the material particles are kept in a dynamic state in the hopper, making it easier for dust to separate and be discharged. The dust will float up and be extracted by the fan, which can thoroughly remove the dust between the material particles, ensuring that the plastic particles entering the subsequent processing stage have high purity. This effectively reduces product defects caused by dust contamination, improves the quality and performance of plastic products, and enhances the product's competitiveness in the market.

[0039] 2. The space frame is placed in one of the slots of the double-slot frame by personnel, and the push plate is driven to move, thereby moving the space frame inside the double-slot frame and pushing it into the wind box. The space frame can be quickly sent into the wind box without disassembly, which effectively improves the convenience of operation and work efficiency. In addition, a frame is set up to compress the space frame. When the old space frame is pulled out, the frame can compress the new space frame into the position where the old space frame was installed, which effectively improves the stability of the operation and avoids improper installation.

[0040] 3. The filter replacement mechanism enables convenient installation and disassembly without stopping the machine, greatly reducing downtime and significantly improving production efficiency. This makes the production process more continuous and stable. Compared with existing technologies, it can effectively increase the amount of plastic granules processed per unit time, meeting the needs of large-scale production. Furthermore, the multi-stage pipe can block the new screen frame from moving down before the second square rod returns to the chute, preventing jamming inside the air box and ensuring that the filter frame can be installed accurately and stably in the correct position, thus effectively improving installation stability.

During the movement, the material particles are kept in a dynamic state in the hopper, making it easier for dust to be separated and discharged.

[0051] The filter replacement mechanism 200 includes the following parts: a square hole 211 is opened on one side of the outer wall of the air box 210 near the bottom. An arc-shaped frame 213 is rotatably connected inside the square hole 211. A coil spring 214 is fixedly connected between the inner wall of the square hole 211 and the pivot of the arc-shaped frame 213. A double-groove frame 230 is fixed on one side of the air box 210 near the square hole 211 and the square hole 212. Arc-shaped grooves 231 are opened on both sides of the outer wall of the double-groove frame 230 near one end. Two elastic push rods 232 are provided and fixed on both sides of the outer wall of the air box 210. A rack 233 is fixedly connected to one end of the elastic push rod 232. The outer wall of the rack 233 is slidably inserted into the outer wall of the double-groove frame 230. A push plate 239 is fixed between the outer walls of the two racks 233. An electric push rod 240 is fixed to the air box. On one side of the outer wall of 210, a U-shaped frame 241 is fixedly connected to one end of an electric push rod 240. A round rod 243 rotates on the outer wall of the U-shaped frame 241. A spur gear 244 is fixedly connected to both ends of the round rod 243. The motor 242 is fixed to the outer wall of one end of the U-shaped frame 241. The shaft of the motor 242 is fixedly connected to one end of the round rod 243. The frame 250 slides inside the wind box 210. Springs 252 are fixedly connected to all four ends of the frame 250. A limit seat 251 is fixedly connected to one end of the spring 252. The outer wall of the limit seat 251 is fixed to the inner wall of the wind box 210.

The net frame can be quickly sent into the wind box 210 without disassembly.

[0052] The filter replacement mechanism 200 includes the following parts: a square hole 212 is opened on one side of the outer wall of the air box 210 near the square hole 211; an arc-shaped frame 215 is rotatably connected inside the square hole 212; a coil spring 216 is fixedly connected between the inner wall of the square hole 211 and the rotating shaft of the arc-shaped frame 215; two elastic push rods 234 are provided, respectively fixed on the outer walls of the double-groove frame 230; a rack 235 is fixedly connected to one end of the elastic push rod 234; the outer wall of the rack 235 is slidably inserted into the outer wall of the air box 210; and a square rod 236 is fixed to the rack 235. At one end of 235, a round block 237 is fixedly connected to one end of square rod 236. The round block 237 is slidably inserted into the sliding hole 217. Square rod 238 is fixed between the two round blocks 237 and is slidably inserted into the sliding groove 218. A set of multi-stage tubes 220 is provided. The sliding tube is fixed on square rod 238, and the insertion tube is fixed on the outer wall of the air box 210. The filter replacement mechanism 200 can realize convenient installation and disassembly. The replacement operation can be carried out without stopping the machine, which greatly reduces the downtime of the equipment, significantly improves the production efficiency, and makes the production process more continuous and stable.

[0053] Specifically, during operation, the operator first inserts the feed pipe of the machine body 110 into the interior of the raw material. Then, the operator turns on the blower 120. The blower 120 then extracts the air from the upper part of the machine body 110. Due to the negative pressure, the raw material enters the interior of the machine body 110 through the feed pipe, located above the hopper 130. Dust is drawn into the air box 210 by the blower 120. The air containing dust is then filtered and discharged through the outlet pipe at one end of the air box 210, completing the dust extraction and collection. During operation, the electric push rod 323 drives the square plate 321 to reciprocate, causing the rack 322 to mesh with the gear ring 310, thereby causing the hopper 130 to swing back and forth, and causing the hopper 130 to move upwards. The piled raw materials are shaken, and with the operation of the blower 120, all the dust trapped between the raw materials can be sucked out. When the amount of raw materials sucked in reaches a suitable level, the electric push rod 323 drives the square plate 321 to move to one side, separating it from the center of the hopper 130. Then the raw materials fall down along the center of the hopper 130 and are discharged from the outlet along the slope. Then the next step of the operation can be carried out to complete the work. When it is necessary to replace the filter screen frame inside the machine body 110, the personnel place the new filter screen frame in the upper slot of the double slot frame 230. The electric push rod 240 drives the U-shaped frame 241 to move upward, causing the spur gear 244 to engage with the rack 233. The motor 242 drives the round rod 243 to rotate, driving the spur gear. 244 meshes with rack 233, driving push plate 239 to move towards body 110, pushing the filter to be replaced into the air box 210. One end of the filter frame contacts arc frame 213, which is squeezed and flips to one side, allowing the filter to enter the air box 210. When arc frame 213 separates from the filter, it returns to its original position due to the rebound of coil spring 214, sealing the square hole 211. When the filter is inside the air box 210, frame 250 is squeezed by spring 252, making the new filter tightly adhere to the filter to be replaced. Electric push rod 240 drives U-shaped frame 241 to move downward until spur gear 244 engages with rack 235. Motor 242 drives spur gear 244 to rotate and engage with rack 235. When bar 235 engages, it moves square bar 238 and pushes the old grid frame out through the slot below the double-groove frame 230. During this process, multi-stage pipe 220 is extended to block the new grid frame from moving down. When the old grid frame comes into contact with arc frame 215, it is squeezed and flipped to one side until the old grid frame is discharged. Arc frame 215 returns to its original position due to the rebound of spring 216 and is sealed. Personnel remove the grid frame through the slot below the double-groove frame 230 to complete the replacement. Electric push rod 240 drives the spur gear 244 to separate from rack 235. Due to the rebound of elastic push rod 234, square bar 238 returns to the inside of slide 218. At this time, the new grid frame inside the wind box 210 is squeezed down by frame 250 to the correct installation position.

[0054] Example 1

[0055] like Figure 7 As shown, in this embodiment, the shaking mechanism 300 includes the following parts: its gear ring 310 is fixed to the bottom of the hopper 130, and two arc plates 320 are provided, which are fixed at equal angles to the inside of the machine body 110 below the hopper 130. The square plate 321 slides between the outer walls of the two arc plates 320. A rack 322 is fixedly connected to the outer wall of the square plate 321, and the rack 322 meshes with the gear ring 310 for transmission. Its electric push rod 323 is fixed to the outer wall of the machine body 110, and one end of the electric push rod 323 is fixedly connected to the outer wall of the square plate 321.

[0056] In this embodiment, during operation, the electric push rod 323 drives the square plate 321 to reciprocate, causing the rack 322 to mesh with the gear ring 310, which in turn causes the hopper 130 to sway back and forth, causing the raw materials accumulated on the hopper 130 to shake. In conjunction with the operation of the fan 120, all dust trapped between the raw materials can be sucked out. The electric push rod 323 drives the rack 322 to move and mesh with the gear ring 310, causing the hopper 130 to sway back and forth, thus causing the raw materials to shake. During this movement, the material particles are kept in a dynamic state within the hopper, making it easier for dust to separate and be discharged. The dust will float up, and with the help of the fan 120, the dust between the material particles can be completely removed, ensuring the high purity of the plastic particles entering subsequent processing stages. This effectively reduces product defects caused by dust contamination, improves the quality and performance of plastic products, and enhances the product's competitiveness in the market.

[0057] like Figure 3-6As shown, in this embodiment, the filter replacement mechanism 200 includes the following parts: a square hole 211 is opened on one side of the outer wall of the air box 210 near the bottom; an arc-shaped frame 213 is rotatably connected inside the square hole 211; a coil spring 214 is fixedly connected between the inner wall of the square hole 211 and the rotating shaft of the arc-shaped frame 213; a double-groove frame 230 is fixed on one side of the air box 210 near the square hole 211 and the square hole 212; arc-shaped grooves 231 are opened on both sides of the outer wall of the double-groove frame 230 near one end; two elastic push rods 232 are provided, respectively fixed on both sides of the outer wall of the air box 210; a rack 233 is fixedly connected to one end of the elastic push rod 232; and the outer wall of the rack 233 is connected to the double groove. The frame 230 is slidably inserted into the outer wall, and the push plate 239 is fixed between the outer walls of the two racks 233. The electric push rod 240 is fixed on the outer wall of one side of the bellows 210. A U-shaped frame 241 is fixedly connected to one end of the electric push rod 240. The round rod 243 rotates on the outer wall of the U-shaped frame 241. Spur gears 244 are fixedly connected to both ends of the round rod 243. The motor 242 is fixed to the outer wall of one end of the U-shaped frame 241. The rotating shaft of the motor 242 is fixedly connected to one end of the round rod 243. The frame 250 slides inside the bellows 210. Springs 252 are fixedly connected to all four ends of the frame 250. A limit seat 251 is fixedly connected to one end of the spring 252. The outer wall of the limit seat 251 is fixed to the inner wall of the bellows 210.

[0058] In practice, the new filter frame is placed in the upper slot of the double-slot frame 230. The electric push rod 240 drives the U-shaped frame 241 upwards, causing the spur gear 244 to engage with the rack 233. The motor 242 drives the round rod 243 to rotate, causing the spur gear 244 to mesh with the rack 233, moving the push plate 239 towards the machine body 110. This pushes the filter to be replaced into the air box 210. One end of the filter frame contacts the arc-shaped frame 213, which is then squeezed and flipped to one side, allowing the filter to enter the air box 210. When the arc-shaped frame 213 separates from the filter frame, it returns to its original position due to the rebound of the coil spring 214. The square hole 211 is sealed. When the mesh frame is inside the bellows 210, the frame 250 is compressed by the spring 252, making the new mesh frame fit tightly against the mesh frame to be replaced. The mesh frame is placed in one of the slots of the double-slot frame 230 by personnel, and the push plate 239 is driven to move, thereby moving the mesh frame inside the double-slot frame 230 and pushing it into the bellows 210. The mesh frame can be quickly sent into the bellows 210 without disassembly, which effectively improves the convenience of operation and work efficiency. In addition, the frame 250 is set to compress the mesh frame. When the old mesh frame is pulled out, the frame 250 can compress the new mesh frame to the position where the old mesh frame was installed, which effectively improves the stability of operation and avoids improper installation.

[0059] Example 2

[0060] like Figure 3-6 As shown, in this embodiment, the filter replacement mechanism 200 includes the following parts: a second square hole 212 is opened on one side of the outer wall of the air box 210 near the first square hole 211; an arc-shaped frame 215 is rotatably connected inside the second square hole 212; a coil spring 216 is fixedly connected between the inner wall of the first square hole 211 and the rotating shaft of the arc-shaped frame 215; two elastic push rods 234 are provided, respectively fixed on the outer walls of both sides of the double-groove frame 230; and a rack is fixedly connected to one end of the elastic push rod 234. The outer wall of rack 235 is slidably inserted into the outer wall of bellows 210. The square rod 236 is fixed at one end of rack 235. A round block 237 is fixedly connected to one end of square rod 236. The round block 237 is slidably inserted into sliding hole 217. The square rod 238 is fixed between the two round blocks 237 and is slidably inserted into sliding groove 218. A set of multi-stage pipes 220 is provided. The sliding pipe is fixed on square rod 238, and the insertion pipe is fixed on the outer wall of bellows 210.

[0061] In practice, the electric push rod 240 drives the U-shaped frame 241 downwards until the spur gear 244 engages with the rack 235. The motor 242 drives the spur gear 244 to rotate and mesh with the rack 235, moving the square rod 238 and pushing the old mesh frame out through the slot below the double-groove frame 230. During this process, the multi-stage pipe 220 is extended, blocking the new mesh frame from moving downwards. When the old mesh frame comes into contact with the arc-shaped frame 215, it is squeezed and flipped to one side until the old mesh frame is discharged. The arc-shaped frame 215 returns to its original position due to the rebound of the coil spring 216, sealing it. Personnel then remove the mesh frame through the slot below the double-groove frame 230, completing the replacement. Through the meshing of the spur gear 244 and the rack 235, the square rod 238 can be moved. The filter screen to be replaced inside the bellows 210 is quickly pushed out through the lower slot of the double-groove frame 230, effectively improving disassembly efficiency. The filter screen replacement mechanism 200 enables convenient installation and disassembly without stopping the machine, greatly reducing equipment downtime and significantly improving production efficiency. This makes the production process more continuous and stable. Compared with existing technologies, it can effectively increase the amount of plastic granules processed per unit time, meeting the needs of large-scale production. Furthermore, the multi-stage pipe 220 can block the new filter screen from moving down before the square rod 238 returns to the slide 218, preventing jamming inside the bellows 210 and ensuring that the filter screen to be installed is accurately and stably installed in the correct position, thus effectively improving installation stability.
