Description

[0001] The invention belongs to the technical field of recycled plastic processing, and in particular relates to an automatic batching and feeding device for recycled plastic particle processing. Background Art

[0002] The development of the plastic industry has brought great benefits to mankind, but it has also left behind endless troubles, namely "white pollution". Since the advent of plastic products, old plastics have inevitably been produced, and as time goes by, more new raw materials are put into use, causing a substantial increase in waste plastics. Since waste plastics are not easy to age and degrade at room temperature, they form an increasing white pollution, causing serious damage to the ecological environment. In order to rationally recycle waste plastics and achieve circular utilization, waste plastics are processed into plastic recycled particles.

[0003] In actual use, when processing recycled plastic particles, waste plastic is not used alone as raw material.

The hydraulic cylinder 401 is fixedly connected to the bottom surface of the mounting plate 301, the piston rod 402 is symmetrically arranged on the hydraulic cylinder 401, the piston rod 402 penetrates and is slidably connected to the hydraulic cylinder 401, one end of the piston rod 402 away from the hydraulic cylinder 401 is fixedly connected to the movable baffle 309, the auxiliary box 403 is fixedly connected to the bottom surface of the mounting plate 301, the flip plate 404 is rotatably connected to the auxiliary box 403, the fixing ring 405 is fixedly connected to the auxiliary box 403, one end of the horizontal torsion spring 406 is fixedly connected to the fixing ring 405, the other end of the horizontal torsion spring 406 is fixedly connected to the flip plate 404, and the manual push plate 407 penetrates and is slidably connected to the auxiliary box 403.

[0042] The fixed support structure 1 includes a fixed base 101, a vertical bracket 102, a fixed plate 104, a driving threaded rod 105, a lifting rack 106 and a connecting plate 107.

[0044] The first rotating shaft 204 and the second rotating shaft 205 are symmetrically arranged, the threaded structures on the outer surface of the limiting slide groove 216 are symmetrically arranged, the limiting groove 213 is symmetrically arranged on the limiting slide groove 216, and the limiting groove 213 is threadedly connected to the limiting slide groove 216.

[0045] The meshing teeth 313 are meshedly connected to the fixed teeth 310 , the docking teeth 321 are meshedly connected to the lifting rack 106 , the fixed shaft 303 is arranged at the middle position of the movable connecting rod 304 , and the movable connecting rod 304 is symmetrically arranged on the fixed shaft 303 .

[0046] The bidirectional screw 217 penetrates through and is rotatably connected to the vertical bracket 102 . The adjusting wheel 209 is in the shape of a truncated cone, and a pattern structure for increasing friction is provided on the outer surface of the adjusting wheel 209 .

[0047] One end of the blade 221 away from the rotating shaft 220 is configured to be circular, and the other end of the blade 221 away from the rotating shaft 220 abuts against the inner surface of the feed box 219 .

[0048] During specific use, the adjusting wheels 209 provided on the rotating shaft 1 204 and the rotating shaft 2 205 are adjusted according to the ratio of materials to be conveyed, and the staff manually rotates the bidirectional screw 217. The rotation of the bidirectional screw 217 drives the connecting bracket 214 to move relatively along the docking plate 215. The displacement of the docking plate 215 drives the adjusting wheel 209 to move along the key shaft 208. As the position of the adjusting wheel 209 is adjusted, the speed ratio between the rotating shaft 1 204 and the rotating shaft 2 205 is adjusted accordingly. After the adjustment of the adjusting wheel 209 is completed, the staff manually rotates the driving threaded rod 105. The driving threaded rod 105 rotates through the connecting plate 107 to drive the lifting rack 106 to adjust its position along the lifting chute 103, so that the position of the lifting rack 106 is also set according to the specified ratio.

[0049] After the positions of the adjusting wheel 209 and the lifting rack 106 are adjusted, the materials needed for processing are poured into the two feed boxes 219 respectively, and then the driving motor 201 is started. After the driving motor 201 is started, the driving pulley 203 is driven to rotate through the output shaft 202, and the driving pulley 203 drives the driven pulley 206 to rotate through the transmission belt 207, and the driven pulley 206 drives the rotating shaft 1 204 to rotate. The rotating shaft 1 204 drives the rotating shaft 2 205 to rotate according to a preset ratio through the adjusting wheel 209 and the power transmission belt 210, and the rotating shaft 1 204 and the rotating shaft 2 205 respectively drive the rotating shaft 220 to rotate inside the feed box 219 through the key shaft 208, so that the material inside the feed box 219 falls into the weighing box 306 in proportion.

[0050] After the material enters the weighing box 306, it will be displaced by force. Since the material enters the weighing box 306 in proportion, the weighing box 306 is subjected to different gravity. The weighing box 306 will drive the movable connecting rod 304 to rotate through the fixed shaft 303. At this time, the heavier weighing box 306 will be displaced downward, and the lighter weighing box 306 will be displaced upward. When the weight of the material in the weighing box 306 is not proportional, the heavier weighing box 306 will move downward. The docking tooth 321 provided on the outer surface of the block 319 is meshed with the lifting rack 106. At this time, the lighter weighing box 306 connected to the other end of the movable connecting rod 304 has not reached the specified height, and the heavier weighing box 306 continues to move downward. The block 319 provided on the heavier weighing box 306 will rotate under the action of the lifting rack 106, so that the block 319 is separated from the limit tooth 317. At this time, the rotation of the limit pulley 316 is no longer restricted, and the heavier weighing box 306 continues to move downward. The rotating pulley 312 set on the weighing box 306 loses its restriction and rotates under the action of the vertical torsion spring 314. At this time, the rotating pulley 312 will drive the movable baffle 309 to move through the meshing teeth 313 set on its outer surface and the fixed teeth 310 set on the upper surface of the movable baffle 309. However, the displacement of the movable baffle 309 alone cannot drive the piston rod 402 to move, because the thrust generated by the displacement of the movable baffle 309 alone cannot make the flip plate 404 overcome the supporting force provided by the horizontal torsion spring 406 and rotate. Therefore, the movable baffle 309 cannot move, and the movable baffle 309 at the bottom of the heavier weighing box 306 cannot be opened. The lighter weighing box 306 has not released the restriction of the block 319. At this time, the material cannot enter the auger conveyor for loading, and the staff is required to adjust the position of the adjusting wheel 209 and the lifting rack 106 to ensure that the loading ratio of the material is correct.

[0051] When the material feeding ratio is correct, the heavier weighing box 306 and the lighter weighing box 306 reach the specified position at the same time and make the block 319 rotate, contacting the limit of the rotating pulley 312. At this time, the two movable baffles 309 simultaneously drive the piston rod 402 to move. The extrusion force generated by the common position of the piston rod 402 can overcome the supporting force of the horizontal torsion spring 406 and drive the flip plate 404 to rotate. At this time, the hydraulic oil in the hydraulic cylinder 401 enters the auxiliary box 403 under the action of the piston rod 402. After the movable baffle 309 is opened, the material passes through the weighing box 306 and enters the auger conveyor to complete the loading. After the movable baffle 309 is opened and the material enters the auger conveyor, the two weighing boxes 306 return to a horizontal state. At this time, the weighing box 306 will drive the block 319 to abut against the limit tooth 317 during the resetting process. At this time, the limit pulley 316 cannot rotate, and the rotating pulley 312 cannot rotate. The movable baffle 309 cannot be reset to a closed state, which can ensure that the material can be loaded normally.

[0052] When it is necessary to load materials according to a new ratio, the position of the adjusting wheel 209 and the lifting rack 106 can be readjusted, and the block 319 can be manually rotated to contact the limit of the movable baffle 309, and the manual push plate 407 can be pushed. The hydraulic cylinder 401 and the hydraulic oil inside the auxiliary box 403 are also reset, and the movable baffle 309 is closed again. During the closing process of the movable baffle 309, the vertical torsion spring 314 is driven to twist again. After the movable baffle 309 is closed, the block 319 is used to abut against the limit tooth 317 again to limit the rotation of the limit pulley 316. The above is the overall workflow of the present invention. Just repeat this step when you use it next time. The actual operation process is very simple and easy.
