[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-3 As shown, the present utility model is a plastic coffee cup lid conveyor, including a machine body 1. A conveyor belt 2 is fixedly installed on the workbench of the machine body 1. Side baffles 11 are fixedly installed on both sides of the machine body 1. The tops of the two side baffles 11 are fixedly connected by two connecting plates 12. A plurality of shunt baffles 13 are fixedly connected to the bottoms of the two connecting plates 12. The plurality of shunt baffles 13 divide the conveyor belt 2 into a plurality of conveying channels. The normal diameter of a coffee cup lid is about 10 cm. Each conveying channel is set to have a width that can just pass through one coffee cup lid. In this design, the plurality of shunt baffles 13 are set to three, and the three shunt baffles 13 divide the conveyor belt 2 into four conveying channels.

[0023] Frame one 3 is fixedly installed on the frames on both sides of the machine body 1. A fixed base 32 is fixedly installed at the bottom of the top cross - bar of the frame one 3. A screening camera 31 is fixedly installed at the bottom of the fixed base 32. The screening camera 31 is used to detect whether the coffee cup lids passing through the channels are damaged or defective, and whether they are placed upside down. And the screened data is transmitted to the plc control system.

[0024] A flip mechanism 6 is fixedly installed on the adjacent flow diversion baffles 13. The flip mechanism 6 includes two groups of support plates 61 fixedly installed on two adjacent flow diversion baffles 13. An end plate 69 is fixedly installed at the top of the two groups of support plates 61. A rotating shaft 62 is rotatably installed in the middle of a pair of opposite support plates 61. A telescopic rod 63 is fixedly installed at the bottom of the rotating shaft 62. A second suction cup 64 is installed at the bottom of the telescopic rod 63. The second suction cup 64 is connected to an external air pump. The top of the rotating shaft 62 is fixedly connected to a connecting rod 65. The top of the connecting rod 65 is movably connected to an L-shaped pull rod 66. A groove is formed at the other end of the L-shaped pull rod 66. A shaft rod 67 is connected in the grooves at the tops of the two L-shaped pull rods 66. A telescopic cylinder 68 is fixedly connected to the bottom of the shaft rod 67. The bottom of the cylinder body of the telescopic cylinder 68 is fixedly installed on the end plate 69. The end of the output shaft of the telescopic cylinder 68 is fixedly connected to the shaft rod 67. When a coffee cup lid placed in the wrong direction passes through the conveying channel and is detected by the screening camera 31, the screening camera 31 transmits the screened data to the plc control system. The plc control system issues a flip command to the flip mechanism 6. First, the second suction cup 64 in the front group adsorbs the inverted coffee cup lid. At this time, the second suction cup 64 in the rear group does not provide adsorption force. Then, the output end of the telescopic cylinder 68 contracts inward, thereby driving the L-shaped pull rod 66 to pull the rotating shaft 62 to rotate. The predetermined rotation angle of the rotating shaft 62 is 90 degrees. At this time, the two second suction cups 64 are opposite to each other on both sides of the coffee cup lid. At this time, the second suction cup 64 in the rear group is controlled to provide adsorption force, and the adsorption force of the second suction cup 64 in the front group is withdrawn. At this time, the coffee cup lid is adsorbed on the second suction cup 64 in the rear group. Then, the output end of the telescopic cylinder 68 jacks outwards, thereby driving the L-shaped pull rod 66 to pull the rotating shaft 62 to rotate and place the flipped coffee cup lid back on the conveying channel.

[0025] In order to ensure that the flipping process in the previous step is not affected by the coffee cup lids transported from the back, a rotating baffle 5 is rotatably installed among multiple flow diversion baffles 13. The rotating baffle 5 is located in front of the flip mechanism 6. When flipping, the rotating baffle 5 rotates to block the cup lids behind.

[0026] Embodiment 2

[0027] On the basis of the above embodiments, a second frame 4 is fixedly installed on the frame on one side of the body 1. The other side of the second frame 4 is installed on the ground. A linear guide rail is fixedly installed at the bottom of the top cross bar of the second frame 4. A sliding block is slidably installed on the linear guide rail. A base 42 is fixedly installed at the bottom of the sliding block. A motor is installed on the base 42 to provide drive so that the base 42 can slide back and forth on the linear guide rail. A lifting cylinder 43 is fixedly installed at the bottom of the base 42. A connecting block is fixedly connected to the end of the output shaft of the lifting cylinder 43. A first suction cup 45 is fixedly installed at the bottom of the connecting block. The first suction cup 45 is connected to an external air pump and provides suction force. A collection box 7 is arranged on one side of the second frame 4. When the screening camera 31 detects that the coffee cup lids passing through the channel are damaged or defective, the screened data is transmitted to the PLC control system. The PLC control system controls the linkage structure at the bottom of the second frame 4 to adsorb the defective coffee cup lids and place the adsorbed defective coffee cup lids into the collection box 7.

[0028] Working principle: When the device is working, first, the screening camera 31 is used to detect whether the coffee cup lids passing through the channel are damaged or defective, and whether they are placed upside down. And the screened data is transmitted to the PLC control system. When the screening camera 31 detects that the coffee cup lids passing through the channel are damaged or defective, the PLC control system controls the linkage structure at the bottom of the second frame 4 to adsorb the defective coffee cup lids and place the adsorbed defective coffee cup lids into the collection box 7. When the upside-down coffee cup lids pass through the conveying channel and are detected by the screening camera 31, the screening camera 31 transmits the screened data to the PLC control system. The PLC control system issues a command to the flipping mechanism 6 to flip the coffee cup lids. First, a group of second suction cups 64 at the front end adsorb the upside-down coffee cup lids. At this time, the group of second suction cups 64 at the back does not provide suction force. Then the output end of the telescopic cylinder 68 contracts inward, thereby driving the L-shaped pull rod 66 to pull the rotating shaft 62 to rotate. The predetermined rotation angle of the rotating shaft 62 is 90 degrees. At this time, the two groups of second suction cups 64 are opposite to each other on both sides of the coffee cup lid. At this time, the group of second suction cups 64 at the back is controlled to provide suction force, and the group of second suction cups 64 at the front end cancels the suction force. At this time, the coffee cup lid is adsorbed onto the group of second suction cups 64 at the back. Then the output end of the telescopic cylinder 68 jacks outwards, thereby driving the L-shaped pull rod 66 to pull the rotating shaft 62 to rotate and place the flipped coffee cup lid back onto the conveying channel.

[0029] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
