[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 9The embodiment of the present invention provides a cup discharging device suitable for plastic containers, comprising a conveyor belt 1, a charging mechanism 2 provided on the outside of the conveyor belt 1, a cup discharging mechanism 3 provided on the outside of the conveyor belt 1, and a cleaning mechanism 4 provided at the bottom of the conveyor belt 1. The charging mechanism 2 can inflate the cleaning mechanism 4, and the cleaning mechanism 4 can provide operating power for the cup discharging mechanism 3. A pressure stabilizing mechanism 5 is provided on the outside of the cleaning mechanism 4, and the pressure stabilizing mechanism 5 is used to discharge excess gas in the pressure stabilizing mechanism 5. Two turning wheels 7 are fixedly connected to the outside of the driving shaft of the conveyor belt 1, and a conveyor belt 6 is provided on the side of the conveyor belt 1 away from the cup discharging mechanism 3. After the plastic container moves from the conveyor belt 1 to the position of the turning wheel 7, due to the rotation of the turning wheel 7, if the cylindrical container is in a vertical state, it cannot enter the groove of the turning wheel 7. Therefore, as the turning wheel 7 rotates, the conveyor belt 1 can continuously adjust the position of the plastic container. When the plastic container is in a horizontal state, it will fall into the groove of the turning wheel 7 and follow the rotation of the turning wheel 7 to move to the conveyor belt 6. Therefore, the plastic containers on the conveyor belt 6 are all arranged in a vertical state for transportation.

[0033] The charging mechanism 2 includes a housing 201, which provides an installation position. The outside of the housing 201 is fixedly connected to the outside of the conveyor belt 1. The inside of the housing 201 is slidably connected to a piston 202. The piston 202 slides inside the housing 201 to inflate. The side of the piston 202 close to the flip wheel 7 is fixedly connected to a sliding plate 203. The sliding plate 203 plays a connecting role. The side of the sliding plate 203 close to the flip wheel 7 is fixedly connected to a slider 204. The outside of the conveyor belt 1 is fixedly connected to a slide rail 205. The slider 204 slides on the outside of the slide rail 205 to improve the stability of the movement of the slide plate 203. The slider 204 is slidably connected to the outside of the slide rail 205. The side of the shell 201 away from the slide plate 203 is fixedly connected to a one-way valve 1 206. The side of the shell 201 away from the piston 202 is fixedly connected to a one-way valve 207. The one-way valve 1 206 and the one-way valve 207 can perform one-way ventilation. The driving shaft of the conveyor belt 1 is fixedly connected to an eccentric wheel 208. The external rotation of the eccentric wheel 208 is connected to a linkage rod. 209, the eccentric wheel 208 can drive the linkage rod 209 to move, thereby driving the piston 202 to move. The end of the linkage rod 209 away from the eccentric wheel 208 is fixedly connected to the end of the slide plate 203 away from the piston 202. When the cup is discharged, the conveyor belt 1 is first started. After the driving shaft of the conveyor belt 1 rotates, it can drive the eccentric wheel 208 to rotate. After the eccentric wheel 208 rotates, it can drive one end of the linkage rod 209 to rotate, and the other end will move back and forth, thereby driving the slide plate 2 03 and the piston 202 move back and forth, and when the piston 202 moves toward the direction of the one-way valve 1 206, the one-way valve 1 206 opens and the one-way valve 2 207 closes. At this time, the air inside the shell 201 will be discharged through the one-way valve 1 206, so that the gas is filled into the interior of the cleaning mechanism 4. When the piston 202 moves toward the direction away from the one-way valve 207, the one-way valve 207 opens and the one-way valve 1 206 closes. At this time, the outside air will enter the interior of the shell 201.

[0034] The cup discharging mechanism 3 includes a storage barrel 301 and an outer barrel 303. The storage barrel 301 provides storage space and is arranged outside the conveyor belt 1. The bottom of the storage barrel 301 is fixedly connected to a cup discharging barrel 302, which can conveniently discharge plastic containers. The inner part of the outer barrel 303 is slidably connected to a sliding ring 304, the bottom of the sliding ring 304 is fixedly connected to a sliding rod 305, and the bottom of the sliding rod 305 is fixedly connected to a blocking plug 306. The movement of the blocking plug 306 can move the plastic container. A return spring 307 is arranged inside the outer barrel 303, and a ventilation groove 308 is provided at the bottom end of the outer barrel 303. The ventilation groove 308 has a ventilation function. The inner bottom end of the outer barrel 303 is provided with multiple The air outlet 309 can discharge gas, and the bottom end of the outer tube 303 is fixedly connected to an exhaust pipe 310, and the exhaust pipe 310 serves to connect the ventilation. The end of the exhaust pipe 310 away from the outer tube 303 is fixedly connected to an exhaust valve 311, and the bottom end of the outer tube 303 is fixedly connected to an air inlet pipe 312, and the air inlet pipe 312 serves to connect the ventilation. The side of the air inlet pipe 312 away from the outer tube 303 is fixedly connected to an automatic valve 313, and the top of the outer tube 303 is fixedly connected to an air outlet cover 314. The sliding rod 305 passes through the bottom of the outer tube 303, and one end of the return spring 307 is fixedly connected to the inside of the sliding rod 305, and the other end of the return spring 307 is fixedly connected to the outer tube 303. At the top, the exhaust pipe 310 and the outside of the air inlet pipe 312 are fixedly connected to the inside of the storage barrel 301. When the plastic container is released from the storage barrel 301, the automatic valve 1 313 is opened, and the automatic valve 1 313 passes the gas into the interior of the outer tube 303 through the air inlet pipe 312. At this time, the gas enters the interior of the outer tube 303 through the vent groove 308 and the air outlet hole 309. At this time, the sliding ring 304 can be pushed upward by air pressure, and then the sliding rod 305 can be driven to move upward and compress the return spring 307. When the sliding rod 305 moves upward, it can drive the blocking plug 306 to move upward. When the blocking plug 306 moves out of the cup tube 302, the interior of the cup tube 302 is not blocked. At this time, the plastic container is discharged from the storage barrel 301. The plastic container can fall out of the storage barrel 301. At the same time, when the blocking plug 306 moves upward, it can move the plastic container inside the storage barrel 301, thereby preventing the cup outlet tube 302 and the plastic container inside the storage barrel 301 from being blocked. When the sliding ring 304 moves to the top of the outer tube 303, the exhaust valve 311 opens and the gas is discharged through the exhaust pipe 310. When the sliding ring 304 needs to fall, the exhaust valve 311 is opened and the automatic valve 1 313 is closed to discharge the gas inside the outer tube 303. Then, under the thrust of the return spring 307, the sliding ring 304 can be driven downward, thereby driving the blocking plug 306 to return to its original position, so that the blocking plug 306 can re-seal the cup outlet tube 302.

[0035] The cleaning mechanism 4 includes an air storage box 401, which has the function of storing gas. The top of the air storage box 401 is fixedly connected to the bottom of the conveyor belt 1. A ventilation pipe 402 is fixedly connected to one side of the air storage box 401. The ventilation pipe 402 serves as a connection. The top of the ventilation pipe 402 is fixedly connected to the end of the one-way valve 206 away from the shell 201. The bottom of the conveyor belt 1 is fixedly connected to a water tank 404. The water tank 404 has the function of storing water. The outer side of the air storage box 401 is fixedly connected to a solenoid valve 413. A connecting pipe is fixedly connected between the water tank 404 and the solenoid valve 413. 403, the bottom of the conveyor belt 1 is fixedly connected to a water pipe 405, the outside of the water pipe 405 is fixedly connected to a plurality of nozzles 406, the outside of the water tank 404 is fixedly connected to an automatic valve 2 414, and a water inlet pipe 411 is fixedly connected between the automatic valve 2 414 and the water pipe 405. The bottom of the conveyor belt 1 is rotatably connected to a rotating shaft 407, the outside of the rotating shaft 407 is fixedly connected to a plurality of cleaning brushes 408, and the end of the rotating shaft 407 close to the charging mechanism 2 is fixedly connected to a gear 409. The bottom of the sliding plate 203 is fixedly connected to a toothed plate 410, and the toothed plate 410 and the gear 409 are fixedly connected. There is a meshing connection between them. A water injection pipe 412 is fixedly connected to the side of the water tank 404 away from the water inlet pipe 411. The top of the water injection pipe 412 is threadedly connected to a sealing cover. The end of the automatic valve 1 313 away from the air inlet pipe 312 is fixedly connected to the outside of the gas storage box 401. After the gas enters the interior of the gas storage box 401 through the vent pipe 402, the gas storage box 401 can be used to store the gas. The solenoid valve 413 is opened, and the gas enters the interior of the water tank 404 through the connecting pipe 403. After the air pressure inside the water tank 404 increases, the automatic valve 2 414 is opened. Under the action of pressure, the gas enters the water tank 404. Liquid can be passed into the interior of the water pipe 405 through the water inlet pipe 411 and sprayed out by the nozzle 406, and then the outer surface of the conveyor belt 1 can be washed to prevent dust accumulation. At the same time, the sliding plate 203 moves back and forth to drive the tooth plate 410 to move back and forth, and the tooth plate 410 drives the gear 409 to rotate back and forth, thereby driving the rotating shaft 407 to rotate back and forth, and then driving the cleaning brush 408 to move back and forth, so that the cleaning brush 408 can be used to clean the outer surface of the conveyor belt 1. At the same time, when the cleaning brush 408 rotates, wind can also be generated to dry the outer surface of the conveyor belt 1.

[0036] The cam 504 is screwed onto the cam 505 and the cam 506 is screwed onto the cam 507. The cam 507 is screwed onto the cam 507 and the cam 506 is screwed onto the cam 507. The movement of the sliding cover 502 can be used to compress the pressure spring 505. When the air bleed hole 503 on the sliding cover 502 moves to the position of the blocking ring 504, the gas will be discharged through the inside of the mounting tube 501 and then discharged to the outside through the air bleed hole 503, thereby preventing the air pressure inside the air storage box 401 from being too high.

[0037] A cup dispensing method adapted for a plastic container comprises the following steps:

[0038] Step 1: Start the conveyor belt 1 and use the driving shaft of the conveyor belt 1 to drive the pressure charging mechanism 2 to operate, thereby generating air pressure and charging it into the interior of the cleaning mechanism 4;

[0039] Step 2: Using the air pressure inside the cleaning mechanism 4 to fill the interior of the outer cylinder 303 can prevent the material inside the storage barrel 301 from being blocked and can control the discharge of the material;

[0040] Step 3: The cleaning mechanism 4 can be used to clean the conveyor belt 1 to prevent dust accumulation on the outer surface of the conveyor belt 1, and the pressure stabilizing mechanism 5 can be used to prevent the air pressure inside the air storage box 401 from being too high.

[0041] Working principle: When discharging cups, the conveyor belt 1 is first started. After the driving shaft of the conveyor belt 1 rotates, it can drive the eccentric wheel 208 to rotate. After the eccentric wheel 208 rotates, it can drive one end of the linkage rod 209 to rotate, and the other end will move back and forth, thereby driving the sliding plate 203 and the piston 202 to move back and forth. When the piston 202 moves in the direction close to the one-way valve 1 206, the one-way valve 1 206 opens and the one-way valve 207 closes. At this time, the air inside the shell 201 will be discharged through the one-way valve 1 206, and the gas will be filled into the interior of the cleaning mechanism 4. When the piston 202 moves in the direction away from the one-way valve 207, the one-way valve 207 opens and the one-way valve 1 206 closes. At this time, the outside air will enter the interior of the shell 201.

[0042] When the plastic container is released from the storage barrel 301, the automatic valve 1 313 is opened, and the automatic valve 1 313 allows gas to enter the interior of the outer tube 303 through the air inlet pipe 312. At this time, the gas enters the interior of the outer tube 303 through the vent groove 308 and the air outlet hole 309. At this time, the sliding ring 304 can be pushed upward by air pressure, and then the sliding rod 305 can be driven to move upward and compress the return spring 307. When the sliding rod 305 moves upward, it can drive the blocking plug 306 to move upward. When the blocking plug 306 moves out of the cup tube 302, the interior of the cup tube 302 is not blocked, and the plastic container can fall out of the storage barrel 301. At the same time, when the blocking plug 306 moves upward, it can move the plastic container inside the storage barrel 301, thereby preventing the cup outlet tube 302 and the plastic container inside the storage barrel 301 from being blocked. When the sliding ring 304 moves to the top of the outer tube 303, the exhaust valve 311 opens and the gas is discharged through the exhaust pipe 310. When the sliding ring 304 needs to fall, the exhaust valve 311 is opened and the automatic valve 1 313 is closed to discharge the gas inside the outer tube 303. Then, under the thrust of the return spring 307, the sliding ring 304 can be driven downward, thereby driving the blocking plug 306 to return to its original position, so that the blocking plug 306 can once again block the cup outlet tube 302.

[0043] After the gas enters the interior of the gas storage box 401 through the ventilation pipe 402, the gas storage box 401 can be used to store the gas, and the solenoid valve 413 is opened, and the gas enters the interior of the water tank 404 through the connecting pipe 403. After the air pressure inside the water tank 404 increases, the automatic valve 2 414 is opened. Under the action of pressure, the liquid can be passed into the interior of the water pipe 405 through the water inlet pipe 411 and sprayed out by the nozzle 406, thereby washing the outer surface of the conveyor belt 1 to prevent dust from accumulating. At the same time, the sliding plate 203 moves back and forth to drive the tooth plate 410 to move back and forth, and the tooth plate 410 drives the gear 409 to rotate back and forth, thereby driving the rotating shaft 407 to rotate back and forth, and then driving the cleaning brush 408 to move back and forth, so that the cleaning brush 408 can be used to clean the outer surface of the conveyor belt 1. At the same time, when the cleaning brush 408 rotates, it can also generate wind force to dry the outer surface of the conveyor belt 1;

[0044] When the pressure inside the air tank 401 is too high, the gas will push the sliding cover 502 away from the air tank 401. The movement of the sliding cover 502 can compress the pressure spring 505. When the air bleed hole 503 on the sliding cover 502 moves to the position of the blocking ring 504, the gas will be discharged through the inside of the mounting tube 501 and then discharged to the outside through the air bleed hole 503, thereby preventing the air pressure inside the air tank 401 from being too high.
