Technical Field

[0001] The invention relates to the technical field of sorting equipment, in particular to an automatic sorting device for plastic cups. Background Art

[0002] Plastic cups are daily necessities commonly used by people. They are widely accepted by people because of their light weight, beautiful appearance and easy to carry characteristics. In daily life, cups are indispensable daily necessities. Although there are many types of cups on the market, such as thermos cups, ordinary water cups, etc. Although these cups have different shapes, their structures are roughly the same, that is, they all include a cup body for holding liquid and a cup handle located on the outside of the cup body and integrated with the cup body for users to hold. With the rapid development of the economy, people's quality of life is getting higher and higher, and the use of cups is also increasing. Plastic cups are a kind of daily utensil, mainly for people to drink beverages. In daily life, people need a stirring rod to stir when brewing beverages to speed up the dissolution of solid beverages. When producing plastic cups, cups need to be sorted.

[0003] At present, when the existing plastic cups are sorted, they are easily affected by external forces and vibrations as the equipment runs, causing the plastic cups to tilt and deviate. In severe cases, the plastic cups may fall over, affecting the normal sorting of the cups and making it inconvenient to sort in batches. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic sorting device for plastic cups, comprising:

[0005] A frame, wherein a discharge notch is provided at a side of the outer side of the frame, and a flat plate is installed at the outer side of the frame and near the discharge notch;

[0006] A feeding mechanism, which is used to linearly feed the plastic cups to be sorted, and is installed in the middle of the top of the frame;

[0007] The feeding mechanism comprises a round roller and a servo motor, the round roller is rotatably mounted at both ends of the top of the frame, the servo motor is mounted on the top of the frame and close to the round roller, the output end of the servo motor is fixedly mounted to the round roller through a coupling, a semicircular groove is provided on the side of the outer cylindrical surface of the round roller, a conveyor belt is installed in the middle of the outer cylindrical surface of the round roller, and an extended rib is fixedly mounted at the corresponding positions on the outer side of the conveyor belt, an arch piece is fixedly mounted on the arc surface on the outer side of the extended rib, and a semicircular block is fixedly mounted on the side of the inner side of the conveyor belt and close to the semicircular groove. The plastic cups to be detected and sorted are placed on the top of the conveyor belt, and the bottom of the plastic cups is located at the position of two adjacent groups of arch pieces, so that the plastic cups can be limited and are not prone to offset. In addition, the material of the arch piece is rubber, which can increase friction, and the arch piece can be elastically deformed, so that it can adapt to plastic cups of different diameters, which has strong adaptability and reduces limitations.

[0008] A sorting mechanism, which is used to sort plastic cups of qualified quality, and is installed in the middle of the top of the frame;

[0009] The sorting mechanism includes a right-angle frame, the bottom of the right-angle frame is fixedly installed at the middle of the outer side of the frame, a camera and an infrared laser generator are installed in sequence at the sides of the outer side of the right-angle frame through a bracket, a cylinder is installed in the middle of the top of the right-angle frame, a bending rod is fixedly installed at the extended end of the cylinder, and an arc-shaped material-moving rod is fixedly installed at the bending part of the outer side of the bending rod, and a guide component is installed on the inner side of the right-angle frame and close to the conveyor belt. The camera is used to shoot the damaged plastic cups, and the infrared laser generator is used to perform infrared inspection on the plastic cups. The temperature distribution on the surface of the cup can be detected by infrared thermal imaging devices, because the heat conduction performance of parts with different thicknesses is different, which will lead to differences in the temperature distribution on the surface of the cup. The temperature distribution on the surface of the cup can be detected by infrared thermal imaging devices, so as to detect the uniformity of the wall thickness of the plastic cup. The staff starts the cylinder to work, and uses the extension of the extended end of the cylinder to push the bending rod downward, so that the arc-shaped material-dispensing rod can be driven to move downward together. The plastic cups with qualified quality can pass the detection of the camera and infrared laser generator smoothly, and the arc-shaped material-dispensing rod is used to contact the plastic cups on the conveyor belt;

[0010] As the plastic cups continue to move toward the discharge notch, the arc-shaped material pusher applies a pushing force to the plastic cups, so that the plastic cups with qualified quality can be pushed away. When unqualified plastic cups are detected, the telescopic end of the cylinder contracts rapidly, thereby driving the arc-shaped material pusher to move upward through the bending rod, so that the unqualified plastic cups do not contact the arc-shaped material pusher, and the unqualified plastic cups continue to be transported, so that the plastic cups can be automatically sorted.

[0011] By rotating the output end of the servo motor, the round roller can be driven to rotate, so that the conveyor belt can be operated, so as to feed the plastic cups that need to be sorted, and drive the plastic cups to move toward the position close to the camera and infrared laser generator, so as to automatically load the materials;

[0012] At the same time, as the conveyor belt continues to run, the unqualified plastic cups are discharged, and under the guidance of the symmetrical extended ribs on both sides, the unqualified plastic cups smoothly enter the discharge gap and fall under the action of the plastic cups' own gravity.

[0013] Preferably, the servo motor and the round roller are installed at the same height, the semicircular blocks are evenly distributed on the inner side of the conveyor belt, and the semicircular blocks are meshingly connected with the semicircular grooves. As the conveyor belt continues to run, the meshing connection between the semicircular blocks and the semicircular grooves can prevent the conveyor belt from slipping, and the plastic cups can be transported accurately without jamming.

[0014] Preferably, the arched pieces are evenly distributed on the arc surface outside the extended rib, and the materials of the extended rib and the arched pieces are both made of rubber.

[0015] Preferably, the camera and the infrared laser generator are in two groups, and the two groups of the camera and the infrared laser generator are symmetrically installed along the conveyor belt, the arc-shaped material-moving rod is installed at an angle, and the arc-shaped material-moving rod is installed directly above the conveyor belt.

[0016] When the bending rod is extended and retracted, it can drive the bending rod to move up and down, and under the guidance of the sliding sleeve, the bending rod is guided. Under the connection of the bending rod, the arc-shaped material-moving rod moves smoothly, thereby promoting the moving of plastic cups with qualified quality.

[0017] Preferably, the guide assembly comprises a U-shaped connecting plate, the U-shaped connecting plate opens downward, and the outer side of the U-shaped connecting plate is fixedly installed with the inner side of the right-angle frame and near the bottom by screws, a sliding sleeve is installed in the middle of the top of the U-shaped connecting plate, and the bottom end of the bending rod passes through the center of the sliding sleeve, and a pin is fixedly installed on the outer side of the U-shaped connecting plate and near the edge of the outer side of the conveyor belt, and a roller is rotatably installed in the middle of the outer cylindrical surface of the pin, and the bottom of the outer cylindrical surface of the roller is fitted with the outer side of the conveyor belt. With the support of the pin, the roller can roll by the operation of the conveyor belt, so that the roller contacts the conveyor belt, and rolling friction can be used to support the conveyor belt, so that the conveyor belt is not prone to jumping when transporting plastic cups.

[0018] Preferably, there are two rollers, and the two rollers are symmetrically installed along the sliding sleeve, and the bottom of the outer circumferential surface of the roller is in contact with the side of the outer side of the conveyor belt.

[0019] Preferably, a material receiving mechanism is installed on the outer side of the frame and close to the arc-shaped material shifting rod, and the material receiving mechanism includes a supporting square column, the bottom of the supporting square column is fixedly installed to the top of the frame by bolts, the position of the supporting square column corresponds to the position of the right-angle frame, and a material guide plate is fixedly installed on the top of the supporting square column and close to the semicircular block, and the position of the material guide plate corresponds to the position of the arc-shaped material shifting rod, and a baffle is fixedly installed on the side of the top of the material guide plate, and a protective component is installed in the middle of the outer side of the supporting square column and close to the material guide plate. When qualified plastic cups are shifted to the position of the material guide plate by the arc-shaped material shifting rod, the material guide plate can be used to receive the qualified plastic cups, and the top blocks are not likely to fall off, and two symmetrical baffles are used to block them, so that the plastic cups on the top of the material guide plate are not likely to scatter.

[0020] Preferably, the material guide plate is installed at an angle, there are two baffles, and the two baffles are installed symmetrically along the central axis in the middle of the material guide plate.

[0021] Preferably, the protective component includes a material guide chute, the top of the material guide chute is rotatably installed through a rotating shaft and the middle of the outer side of the supporting square column, the material guide chute is installed at a position close to the material guide plate, a pressure rod is fixedly installed at the middle of the top of the material guide chute, the pressure rod is installed at a position close to the semicircular block, and an elastic net is fixedly installed in the middle of the inner cavity of the material guide chute. By using the material guide plate to guide the plastic cup, the plastic cup can fall on it, and the elasticity of the elastic net can be used to protect the plastic cup, and it is not easy to cause damage to the plastic cup.

[0022] Preferably, the top of the material guide chute extends to the bottom of the material guide plate, the material guide chute is installed obliquely, the material of the elastic net is made of rubber, and the semicircular blocks move together by the operation of the conveyor belt. When the moving semicircular blocks contact the pressure rod, the pressure rod is subjected to downward pressing force, and under the support of the supporting square column, the material guide chute rotates counterclockwise to adjust the angle;

[0023] As the semicircular block separates from the pressure rod, the pressing force on the pressure rod disappears, and under the action of the material guide chute's own gravity, the material guide chute rotates in the opposite direction to reset, so that the material guide chute can swing back and forth, thereby screening the plastic cups inside the material guide chute, discharging the plastic cups in time, and preventing the accumulation of plastic cups.

[0024] The present invention provides an automatic sorting device for plastic cups, which has the following beneficial effects:

[0025] 1. The automatic sorting device for plastic cups utilizes the extension of the extended end of the cylinder to push the bent rod downward, so that the arc-shaped material-push rod can be driven to move downward together, and the qualified plastic cups can successfully pass the detection of the camera and the infrared laser generator. The arc-shaped material-push rod is used to contact the plastic cups on the conveyor belt, so that the arc-shaped material-push rod exerts a pushing force on the plastic cups, and the qualified plastic cups can be pushed away, and the telescopic end of the cylinder is quickly contracted to lift the arc-shaped material-push rod, so that the unqualified plastic cups do not contact the arc-shaped material-push rod, so that the unqualified plastic cups continue to be conveyed, and the plastic cups can be automatically sorted.

[0026] Second, the automatic sorting device for plastic cups can drive the bending rod to move up and down when the bending rod is extended and retracted to contract and extend, and under the guidance of the sliding sleeve, the bending rod is guided, and under the connection of the bending rod, the arc-shaped material-moving rod moves smoothly, thereby promoting the selection of plastic cups with qualified quality.

[0027] 3. The automatic sorting device for plastic cups can limit the plastic cups by using the bottom of the plastic cups to be located between two adjacent sets of arched pieces, which makes it less likely for the cups to shift. The arched pieces are made of rubber, which increases friction, and the arched pieces can be elastically deformed to accommodate plastic cups of different diameters. The device has strong adaptability and reduces limitations.

[0028] Fourth, the automatic sorting device for plastic cups utilizes the rotation of the output end of the servo motor to drive the round roller to rotate, so that the conveyor belt can be operated, so as to feed the plastic cups that need to be sorted, and drive the plastic cups to move toward the position close to the camera and the infrared laser generator, so that automatic loading can be performed. At the same time, as the conveyor belt continues to operate, the plastic cups with unqualified quality are output, and under the guidance of the symmetrical extended ribs on both sides, the plastic cups with unqualified quality smoothly enter the position of the discharge gap and fall under the action of the plastic cups' own gravity.

[0029] 5. The automatic sorting device for plastic cups, as the conveyor belt continues to run, utilizes the meshing connection between the semicircular block and the semicircular slot to prevent the conveyor belt from slipping, and accurately transports the plastic cups without jamming.

[0030] 6. The automatic sorting device for plastic cups utilizes the bottom of the outer cylindrical surface of the roller to fit with the outer side of the conveyor belt, and under the support of the pin shaft, the roller can roll by the operation of the conveyor belt, so that the roller contacts the conveyor belt, and rolling friction can be used to support the conveyor belt, so that the conveyor belt is not prone to jumping when transporting plastic cups.

[0031] 7. The automatic sorting device for plastic cups can use the guide plate to receive the qualified plastic cups when the qualified plastic cups are tilted to the position of the guide plate by the arc-shaped material-moving rod, so that the top blocks are not likely to fall off, and two symmetrical baffles are used to block the plastic cups on the top of the guide plate, so that the plastic cups are not likely to scatter.

[0032] 8. The automatic sorting device for plastic cups guides the plastic cups by using the guide plate so that the plastic cups can fall onto the surface, and utilizes the elasticity of the elastic net to protect the plastic cups, which is not easy to cause damage to the plastic cups.

[0033] 9. The automatic sorting device for plastic cups uses a moving semicircular block to apply a pressing force to the pressure rod, and under the support of the supporting square column, the material guide chute rotates counterclockwise to adjust the angle. As the semicircular block separates from the pressure rod, the pressing force on the pressure rod disappears, and under the action of the material guide chute's own gravity, the material guide chute rotates in the opposite direction to reset, so that the material guide chute can swing back and forth, and then the plastic cups inside the material guide chute are screened and the plastic cups are discharged in time, which makes it less likely for plastic cups to accumulate.

A conveyor belt 44 is installed in the middle of the outer cylindrical surface of the round roller 41. An extended rib 45 is fixedly installed at the corresponding position on the outer side of the conveyor belt 44. The arc surface on the outer side of the extended rib 45 An arch piece 46 is fixedly installed, and a semicircular block 47 is fixedly installed on the side of the inner side of the conveyor belt 44 and near the semicircular slot 43. The staff will place the plastic cups that need to be inspected and sorted on the top of the conveyor belt 44, and make the bottom of the plastic cups be at the position of the two adjacent sets of arch pieces 46, so that the plastic cups can be limited and not easily offset. In addition, the material of the arch piece 46 is rubber, which can increase the friction force, and the arch piece 46 can be elastically deformed to adapt to plastic cups with different diameters:

[0048] The servo motor 42 and the round roller 41 are installed at the same height, and the semicircular blocks 47 are evenly distributed on the inner side of the conveyor belt 44. The semicircular blocks 47 are meshed and connected with the semicircular grooves 43. As the conveyor belt 44 continues to operate, the meshing connection between the semicircular blocks 47 and the semicircular grooves 43 can prevent the conveyor belt 44 from slipping, and the plastic cups can be transported accurately without jamming.

[0049] The arched pieces 46 are evenly distributed on the arc surface outside the extended rib 45 , and the materials of the extended rib 45 and the arched pieces 46 are both made of rubber.

[0050] The second embodiment, as Figure 1-Figure 6 As shown, based on the first embodiment:

[0051] A sorting mechanism 5, which is used to sort plastic cups of qualified quality, and is installed in the middle of the top of the frame 1;

[0052] The sorting mechanism 5 includes a right-angle frame 51, the bottom of the right-angle frame 51 is fixedly installed in the middle of the outer side of the frame 1, a camera 52 and an infrared laser generator 53 are installed in sequence on the side of the outer side of the right-angle frame 51 through a bracket, a cylinder 54 is installed in the middle of the top of the right-angle frame 51, a bending rod 55 is fixedly installed on the extended end of the cylinder 54, and an arc-shaped material-moving rod 56 is fixedly installed at the bending part of the outer side of the bending rod 55, and a guide component 57 is installed on the inner side of the right-angle frame 51 and close to the conveyor belt 44.

[0053] The staff starts the camera 52 and the infrared laser generator 53 to work, uses the camera 52 to take pictures of the damaged plastic cups, and uses the infrared laser generator 53 to perform infrared detection on the plastic cups. Using the characteristics of thermal radiation, due to the different thermal conductivity of parts with different thicknesses, the temperature distribution on the surface of the cup will be different. The temperature distribution on the surface of the cup can be detected by infrared thermal imaging devices, so as to detect the uniformity of the wall thickness of the plastic cup. The staff starts the cylinder 54 to work, and uses the extension of the extended end of the cylinder 54 to push the bending rod 55 downward, so that the arc-shaped material-displacing rod 56 can be driven to move downward together. The plastic cups with qualified quality pass the detection of the camera 52 and the infrared laser generator 53 smoothly, and the arc-shaped material-displacing rod 56 is used to contact the plastic cups on the conveyor belt 44;

[0054] As the plastic cups continue to move toward the discharge notch 2, the arc-shaped material-push rod 56 exerts a pushing force on the plastic cups, so that the plastic cups with qualified quality can be pushed away. When unqualified plastic cups are detected, the telescopic end of the cylinder 54 contracts rapidly, thereby driving the arc-shaped material-push rod 56 to move upward through the bending rod 55, so that the unqualified plastic cups do not contact the arc-shaped material-push rod 56, so that the unqualified plastic cups continue to be transported, and the plastic cups can be automatically sorted.

[0055] The staff turns on the servo motor 42 to work, and the output end of the servo motor 42 rotates to drive the roller 41 to rotate, so that the conveyor belt 44 can operate, thereby feeding the plastic cups to be sorted, and driving the plastic cups to move toward the position close to the camera 52 and the infrared laser generator 53, so that automatic loading can be performed;

[0056] At the same time, as the conveyor belt 44 continues to operate, the unqualified plastic cups are discharged, and under the guidance of the symmetrical extended ribs 45 on both sides, the unqualified plastic cups smoothly enter the position of the discharge gap 2 and fall under the action of the plastic cups' own gravity.

[0057] There are two groups of cameras 52 and infrared laser generators 53 , and the two groups of cameras 52 and infrared laser generators 53 are symmetrically installed along the conveyor belt 44 . The arc-shaped material-moving rod 56 is installed at an angle, and the arc-shaped material-moving rod 56 is installed directly above the conveyor belt 44 .

[0058] When the bending rod 55 is extended and retracted, it can drive the bending rod 55 to move up and down, and under the guidance of the sliding sleeve 572, the bending rod 55 is guided. Under the connection of the bending rod 55, the arc-shaped material-moving rod 56 moves smoothly, thereby promoting the moving of plastic cups of qualified quality.

[0059] The guide assembly 57 includes a U-shaped connecting plate 571, which opens downward. The outer side of the U-shaped connecting plate 571 is fixedly installed with the inner side of the right-angle frame 51 and near the bottom by screws. A sliding sleeve 572 is installed in the middle of the top of the U-shaped connecting plate 571. The bottom end of the bending rod 55 passes through the center of the sliding sleeve 572. A pin shaft 573 is fixedly installed on the outer side of the U-shaped connecting plate 571 and near the edge of the outer side of the conveyor belt 44. A roller 574 is rotatably installed in the middle of the outer cylindrical surface of the pin shaft 573. The bottom of the outer cylindrical surface of the roller 574 is fitted with the outer side of the conveyor belt 44. With the support of the pin shaft 573, the roller 574 can roll by the operation of the conveyor belt 44, so that the roller 574 contacts the conveyor belt 44, and rolling friction can be used to support the conveyor belt 44, so that the conveyor belt 44 is not prone to jumping when transporting plastic cups.

[0060] There are two rollers 574 , and the two rollers 574 are symmetrically installed along the sliding sleeve 572 , and the bottom of the outer circumferential surface of the roller 574 is in contact with the side of the outer side of the conveyor belt 44 .

[0061] The third embodiment, as Figure 1-Figure 8 As shown, based on the first and second embodiments:

[0062] A material receiving mechanism 6 is installed on the outside of the frame 1 and near the arc-shaped material shifting rod 56. The material receiving mechanism 6 includes a supporting square column 61. The bottom of the supporting square column 61 is fixedly installed to the top of the frame 1 by bolts. The position of the supporting square column 61 corresponds to the position of the right-angle frame 51. A material guide plate 62 is fixedly installed on the top of the supporting square column 61 and near the semicircular block 47. The position of the material guide plate 62 corresponds to the position of the arc-shaped material shifting rod 56. A baffle plate 63 is fixedly installed on the side of the top of the material guide plate 62. A protective component 64 is installed in the middle of the outside of the supporting square column 61 and near the material guide plate 62. When qualified plastic cups are shifted to the position of the material guide plate 62 by the arc-shaped material shifting rod 56, the material guide plate 62 can be used to receive the qualified plastic cups, and it is not easy for the top blocks to fall in between. Two symmetrical baffles 63 are used to block the plastic cups on the top of the material guide plate 62, so that the plastic cups on the top of the material guide plate 62 are not easy to scatter.

[0063] The guide plate 62 is installed at an angle, and there are two baffles 63 , which are installed symmetrically along the central axis in the middle of the guide plate 62 .

[0064] The protection component 64 includes a material guide chute 641. The top of the material guide chute 641 is rotatably installed with the middle of the outer side of the supporting square column 61 through a rotating shaft. The material guide chute 641 is installed at a position close to the material guide plate 62. A pressure rod 642 is fixedly installed at the middle of the top of the material guide chute 641. The pressure rod 642 is installed at a position close to the semicircular block 47. An elastic net 643 is fixedly installed in the middle of the inner cavity of the material guide chute 641. The plastic cup is guided by the material guide plate 62, so that the plastic cup can fall on it. The elasticity of the elastic net 643 can protect the plastic cup and prevent it from being damaged.

[0065] The top of the material guide chute 641 extends to the bottom of the material guide plate 62. The material guide chute 641 is installed obliquely. The material of the elastic net 643 is made of rubber. The semicircular block 47 moves together with the operation of the conveyor belt 44. When the moving semicircular block 47 contacts the pressure rod 642, the pressure rod 642 is pressed downward, and under the support of the supporting square column 61, the material guide chute 641 rotates counterclockwise to adjust the angle.

[0066] As the semicircular block 47 is separated from the pressure rod 642, the pressing force on the pressure rod 642 disappears, and under the action of the gravity of the material guide chute 641 itself, the material guide chute 641 rotates in the opposite direction to reset, so that the material guide chute 641 can swing back and forth, thereby screening the plastic cups inside the material guide chute 641, discharging the plastic cups in time, and preventing the plastic cups from piling up.

[0067] When in use, the staff first places the plastic cups to be inspected and sorted on the top of the conveyor belt 44, and makes the bottom of the plastic cups be located at the positions of two adjacent sets of arched pieces 46, so that the plastic cups can be limited in position and are not easily offset:

[0068] As the conveyor belt 44 continues to run, the semicircular block 47 is meshed with the semicircular slot 43 to prevent the conveyor belt 44 from slipping, and the plastic cups are accurately conveyed without jamming.

[0069] The staff starts the camera 52 and the infrared laser generator 53 to work, uses the camera 52 to take pictures of the damaged plastic cups, and uses the infrared laser generator 53 to perform infrared detection on the plastic cups. Using the thermal radiation characteristics, due to the different thermal conductivity of parts with different thicknesses, the temperature distribution on the surface of the cup will be different. The temperature distribution on the surface of the cup can be detected by infrared thermal imaging devices, so as to detect the uniformity of the wall thickness of the plastic cup. The staff starts the cylinder 54 to work, and uses the extension of the extended end of the cylinder 54 to push the bending rod 55 downward, so that the arc-shaped material-displacing rod 56 can be driven to move downward together. The plastic cups with qualified quality pass the detection of the camera 52 and the infrared laser generator 53 smoothly, and the arc-shaped material-displacing rod 56 is used to contact the plastic cups on the conveyor belt 44;

[0070] The bottom of the outer circumferential surface of the roller 574 is fitted with the outer side of the conveyor belt 44, and the roller 574 can roll with the support of the pin 573 and the conveyor belt 44, so that the roller 574 contacts the conveyor belt 44, and the conveyor belt 44 can be supported by rolling friction, so that the conveyor belt 44 is not easy to jump when transporting plastic cups.

[0071] As the plastic cups continue to move toward the discharge notch 2, the arc-shaped material-push rod 56 exerts a pushing force on the plastic cups, so that the plastic cups with qualified quality can be pushed away. When unqualified plastic cups are detected, the telescopic end of the cylinder 54 contracts rapidly, thereby driving the arc-shaped material-push rod 56 to move upward through the bending rod 55, so that the unqualified plastic cups do not contact the arc-shaped material-push rod 56, so that the unqualified plastic cups continue to be transported, and the plastic cups can be automatically sorted.

[0072] The staff turns on the servo motor 42 to work, and the output end of the servo motor 42 rotates to drive the roller 41 to rotate, so that the conveyor belt 44 can operate, thereby feeding the plastic cups to be sorted, and driving the plastic cups to move toward the position close to the camera 52 and the infrared laser generator 53, so that automatic loading can be performed;

[0073] At the same time, as the conveyor belt 44 continues to run, the unqualified plastic cups are discharged, and under the guidance of the symmetrical extended ribs 45 on both sides, the unqualified plastic cups smoothly enter the position of the discharge gap 2, and fall under the action of the plastic cups' own gravity;

[0074] Moreover, when the qualified plastic cups are tilted by the arc-shaped material-moving rod 56 to the position of the material-moving plate 62, the material-moving plate 62 can be used to receive the qualified plastic cups, and the top pieces are not likely to fall off, and the two symmetrical baffles 63 are used to block the plastic cups on the top of the material-moving plate 62, so that the plastic cups are not likely to fall off.

[0075] The plastic cups are guided by the guide plate 62 so that they can fall onto the surface, and the elasticity of the elastic net 643 protects the plastic cups so that they are not easily damaged.

[0076] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
