Description

Technical Field

[0001] The invention belongs to the technical field of polystyrene processing, in particular to a multi-channel hanging discharging device for polystyrene. Background Art

[0002] As an important chemical raw material, polystyrene has good plasticity and stable chemical properties. Polystyrene is mainly used in the production of foam materials, plastic packaging, automotive parts, electronic components, etc. Its wide application makes the production and processing of polystyrene a key link in the chemical industry.

[0003] In traditional polystyrene processing, the production line usually uses a single-channel discharge device to transport polystyrene particles. However, due to the needs of different products, polystyrene particles of different particle sizes are required to ensure that they can be used in different application scenarios.

[0004] During the polystyrene processing process, the discharging device is suspended and moved on the slide rail by a pulley to drive the discharging device to different positions. However, the pulley cannot be adjusted according to the length between different tracks, which limits the flexibility and adaptability of the production line. In addition, the traditional discharging device transports particles through a single channel, but this single channel cannot meet the classification requirements of polystyrene particles of different particle sizes.

When the multiple first foam plates are not in contact with the second foam plates, the elastic force of the multiple reset springs causes the sorting box to return to its original position, and then the output shaft of the driving motor rotates, and the sorting box swings back and forth with the two sorting boxes as axes. The polystyrene particles are on the upper side of the screening plate. When the sorting box swings back and forth, the polystyrene particles fall onto the lower screening plate through the leakage holes on the upper screening plate. The sieve holes on the two screening plates have different diameters. The sieve holes of the upper screening plate have a larger diameter than the lower screening plate. Polystyrene particles of different sizes are screened out by the two screening plates, so that when using the discharging device, polystyrene of different particle sizes can be screened out, ensuring that polystyrene particles of different particle sizes can be distributed as needed, which helps to accurately select the appropriate particle size in different production processes.

[0023] 3. When the present invention is in use, polystyrene of different particles slide into the interior of the discharge box through multiple partition plates. By turning on the external power switches of the multiple conveying pumps, negative pressure is generated through the multiple first through pipes to suck the polystyrene particles inside the discharge box and discharge them into the interior of the multiple second through pipes. The multiple telescopic hoses have telescopic resilience. By pulling the multiple second through pipes, the outlets of the multiple second through pipes are at the processing position of the production line. The multiple partition plates divide the interior of the discharge box into three parts, which contain polystyrene of different particle sizes. By controlling the switch of one of the conveying pumps, polystyrene of different particle sizes can be conveyed. Therefore, when using the device, polystyrene with different particle size requirements can be conveyed through multiple channels, and the particles can be distributed to different application scenarios, thereby improving the practicality of the device.

[0042] See also Figures 1 to 9 In one embodiment, a discharge box 4 is fixedly provided on one side of the sorting box 302, and a plurality of partition plates 405 are fixedly provided on the inner wall of the discharge box 4. A plurality of first through pipes 401 are installed on one side of the discharge box 4. The plurality of partition plates 405 divide the interior of the discharge box 4 into three parts.

By pulling the multiple second through pipes 403, the outlets of the multiple second through pipes 403 are at the processing position of the production line.

[0044] See also Figures 1 to 9 In one embodiment, pulleys 208 are installed inside the two mounting seats 207, and multiple pulleys 208 are grouped in pairs. Slide rails 209 are slidably provided on the outer surfaces of the two groups of pulleys 208. When the polystyrene raw material is poured into the interior of the base 1, the multiple pulleys 208 can slide on the inner walls of the multiple slide rails 209. By pushing the base 1, the multiple pulleys 208 roll on the inner walls of the slide rails 209, so that the device can be moved to various positions of the production line.

[0045] The working principle and use process of the present invention are as follows: when processing polystyrene, the polystyrene raw material is poured into the interior of the base 1, and multiple pulleys 208 can slide on the inner walls of multiple slide rails 209. By pushing the base 1, the multiple pulleys 208 roll on the inner walls of the slide rails 209, so that the device can be moved to various positions of the production line. The two threaded rods 201 can rotate through the bearings, and the two slide cylinders 205 can slide on the outer surface of the cross bar 204. The two connecting plates 210 connect the two threaded blocks 203 and the two slide cylinders 205 together. By rotating the adjusting disk 211, one of the threaded rods 201 is driven to rotate in different directions, and the other threaded rod is further driven by the connecting rod 202. The threaded rod 201 rotates in different directions, and the thread grooves on the outer surfaces of the two threaded rods 201 rotate in opposite directions. When the adjusting disk 211 rotates in different directions, the two threaded blocks 203 move in relative or opposite directions, and further drive the two slide cylinders 205 to move through the two connecting plates 210. By adjusting the distance between the two connecting plates 210, the distance between the two sets of pulleys 208 is further adjusted through multiple support plates 206 and multiple mounting seats 207. After the distance is adjusted, the multiple pulleys 208 are placed inside the two slide rails 209, and the discharging device is suspended. This ensures that the device can adapt to the distance between different slide rails 209 when in use, thereby enhancing the versatility of the system.

[0046] During discharging, the polystyrene particles are inside the storage bin 313, and under the influence of gravity, they slide down through the inclined surfaces of the two guide plates 305, and then fall into the inside of the sorting box 302 through the discharging pipe 306. The discharging pipe 306 is inside the sorting box 302. At this time, the external power switch of the driving motor 307 is turned on, and the output shaft of the driving motor 307 drives the rotating rod 308 to rotate, so that the multiple first foam plates 309 perform a circular motion. When the multiple first foam plates 309 rotate, they will contact the second foam plates 312 respectively. The multiple first foam plates 309 and the multiple second foam plates 312 are flexible. The sorting box 302 can rotate around the two connecting shafts 303 as the axis, and then when the multiple first foam plates 309 contact the second foam plates 312 in turn, one side of the sorting box 302 will be pressed down by the transmission plate 311, and the two return springs 301 will have elastic force. The two bottom plates 3 are against the two return springs 30 1 has a supporting function. When the multiple first foam plates 309 are not in contact with the second foam plates 312, the elastic force of the multiple return springs 301 causes the sorting box 302 to return to its original position, and then the output shaft of the driving motor 307 rotates, and the sorting box 302 swings back and forth with the two sorting boxes 302 as the axis. The polystyrene particles are on the upper side of the screening plate 304. When the sorting box 302 swings back and forth, the polystyrene particles fall onto the lower screening plate 304 through the leakage holes on the upper screening plate 304. The sieve holes on the two screening plates 304 have different diameters. The sieve hole diameter of the upper screening plate 304 is larger than that of the lower screening plate 304. Polystyrene particles of different sizes are screened out by the two screening plates 304, so that when using the discharging device, polystyrene particles of different sizes can be screened out, ensuring that polystyrene particles of different sizes can be distributed as needed, which helps to accurately select the appropriate particle size in different production processes;

[0047] During discharging, polystyrene of different particles slide into the interior of the discharge box 4 through multiple partition plates 405. By turning on the external power switches of the multiple conveying pumps 402, negative pressure is generated through the multiple first through pipes 401 to suck the polystyrene particles inside the discharge box 4 and discharge them into the interior of the multiple second through pipes 403. The multiple telescopic hoses 404 have telescopic resilience. By pulling the multiple second through pipes 403, the outlets of the multiple second through pipes 403 are at the processing position of the production line. The multiple partition plates 405 divide the interior of the discharge box 4 into three parts. There are polystyrene of different particle sizes inside. By controlling the switch of one of the conveying pumps 402, polystyrene of different particle sizes can be conveyed. Therefore, when using the device, polystyrene with different particle size requirements can be conveyed through multiple channels, and the particles can be distributed to different application scenarios, thereby improving the practicality of the device.
