[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a technical solution: a continuous transfer device for plastic bottle production, comprising: a transfer table 1, a transfer belt 2 provided on the top surface of the transfer table 1, hollow structures provided on the left and right sides of the top of the transfer table 1, a first hydraulic rod 3 installed on the left side of the transfer table 1, a pusher 4 installed on the movable end of the first hydraulic rod 3, a fixed frame 5 fixedly connected to the left side of the transfer table 1, and infrared detectors 6 provided on the upper and lower sides of the right wall of the fixed frame 5, which monitor the upper and lower sides of the bottle body respectively through the infrared detectors 6 on the upper and lower sides.

[0035] A mounting frame 7 is fixedly connected to the right side of the transmission platform 1. Fixing plates 8 are provided on both the front and rear sides of the interior of the mounting frame 7. A through hole 9 is opened inside the mounting frame 7. A detection mechanism 10 is installed on the right side of the interior of the mounting frame 7. A push plate 13 is slidably installed inside the mounting frame 7. After the bottle falls into the fixing plate 8, the push plate 13 pushes the bottle to move to the right.

[0036] A bracket 14 is fixedly connected to the top right side of the mounting frame 7. An electric slide rail 15 is installed on the top bottom side of the bracket 14. A slider 16 is slidably installed on the bottom of the electric slide rail 15. A third hydraulic rod 17 is installed on the bottom of the slider 16. A mounting block 18 is installed on the movable end of the third hydraulic rod 17. A second motor 19 is installed on the rear side of the mounting block 18. An adjusting frame 20 is fixed to the movable end of the second motor 19. The adjusting frame 20 rotates inside the mounting block 18. A third motor 21 is installed at the bottom of the adjusting frame 20. An electric suction cup 22 is fixedly connected to the movable end of the third motor 21 through a coupling. The bottle is adsorbed by the electric suction cup 22.

[0037] The pusher 4 has a hollow internal structure, and the fixing frame 5 is located inside the pusher 4, allowing the pusher 4 to move left and right outside the fixing frame 5. The front and rear individual units of the fixing plate 8 have an inclined structure, and the bottom of the front and rear individual units of the fixing plate 8 forms a hollow groove, so that when the bottle falls into the inner side of the fixing plate 8, it can fall horizontally on the bottom side of the fixing plate 8. The detection mechanism 10 includes a second hydraulic rod 101 installed on the right side of the mounting frame 7. The movable end of the second hydraulic rod 101 is fixedly connected to the mounting plate 102, and a pressure sensor 103 is installed on the left side of the mounting plate 102. A connecting cylinder 104 is fixedly connected to the left side of the mounting plate 102. The connecting cylinder 104 is located to the left of the pressure sensor 103. A detection block 105 is slidably installed inside the left side of the connecting cylinder 104. A spring 106 is installed inside the connecting cylinder 104. The spring 106 resets the detection block 105 to the left. The right end of the spring 106 is in contact with the working end of the pressure sensor 103. When the detection block 105 is squeezed, the pressure value of the pressure sensor 103 changes due to the compression of the spring 106. The detection block 105 is located to the right of the through hole 9 and passes through the interior of the through hole 9, allowing the detection block 105 to be inserted into the interior of the through hole 9. A first motor 11 is installed inside the transmission table 1. A connecting rod 12 is installed at the output end of the first motor 11 through a coupling. The outer surface of the connecting rod 12 has a threaded structure, and the connection between the connecting rod 12 and the push plate 13 is a threaded connection. The bottom working end of the electric suction cup 22 has a semi-circular structure. A positioning frame 23 with an "L" shaped cross-section is fixedly connected to the right side of the transmission station 1. The positioning frame 23 is located to the right of the infrared detector 6. The positioning frame 23 is set to prevent the movable end of the third hydraulic rod 17 from moving up and down and interfering with the infrared detector 6.

[0038] When using the continuous transfer device for plastic bottle production, such as Figure 1 , Figure 2 and Figure 3 The bottle is transported on the conveyor belt 2. An infrared detector 6 is set up to monitor the upper and lower sides of the bottle. The upper infrared detector 6 is positioned higher than the height of the bottle when it is tilted. When the bottle passes vertically, both the upper and lower infrared detectors 6 detect the reflected signal of the bottle. When the bottle is tilted, the conveyor belt 2 moves the bottle past the infrared detector 6. The bottom infrared detector 6 detects the reflected signal, but the top infrared detector 6 does not detect any change in the reflected signal. At this time, the infrared detector 6 sends a signal to the controller through the sensor. The controller controls the first hydraulic rod 3 to drive the pusher 4 to extend to the right, so that the pusher 4 pushes the bottle down through the opening on the right side of the conveyor 1. After the bottle is pushed down, the first hydraulic rod 3 resets.

[0039] like Figure 5 and Figure 7The bottle is inserted into the inner side of the fixing plate 8. The cross-section of the fixing plate 8 is inclined, so that the bottle is kept in a horizontal position on the bottom side of the fixing plate 8. The first motor 11 controls the connecting rod 12 to rotate and drive the push plate 13 to move to the right. The push plate 13 pushes the bottle to the right. When the right side of the push plate 13 is in contact with the outside of the through hole 9, the push plate 13 stops moving.

[0040] like Figure 1 , Figure 4 and Figure 6 The second hydraulic rod 101 drives the detection block 105 to move to the left, passing through the through hole 9 and contacting the bottle body. When the right side of the bottle body is at the bottle opening position, the detection block 105 moves into the bottle opening. Since the position of the detection block 105 does not change, the pressure value of the pressure sensor 103 does not change. The pressure sensor 103 then sends data to the controller. The third hydraulic rod 17 drives the electric suction cup 22 to move downwards to suction the bottle body, and then moves upwards. Based on the data sent by the pressure sensor 103, the controller controls the third motor 21 to rotate the electric suction cup 22, causing the electric suction cup 22 to rotate the bottle body, making the bottle opening face to the left. The slide rail 15 drives the slider 16 to move to the left through the internal drive device. The slider 16 moves the bottle below to the top of the conveyor belt 2. At this time, the conveyor belt 2 continues to work, and the electric suction cup 22 is in a waiting state with the bottle. When the infrared detector 6 detects the next bottle to be tilted, the pusher 4 pushes the bottle down. At this time, there is a space on the conveyor belt 2. The second motor 19 drives the adjusting frame 20 to rotate, so that the adjusting frame 20 moves to a horizontal state and the bottle is in a vertical state. The third hydraulic rod 17 drives the bottle to move downward, so that the bottle is stably placed on the conveyor belt 2. At this time, the electric suction cup 22 separates from the bottle and moves upward. The conveyor belt 2 continues to work to drive the bottle to be transported.

[0041] like Figure 1 and Figure 6 In the above process, when the second hydraulic rod 101 moves the left detection block 105 to the left, the detection block 105 contacts and is squeezed against the bottle, indicating that the bottom of the bottle is at the right end. The detection block 105 moves into the connecting cylinder 104, causing the detection block 105 to squeeze the spring 106. The spring 106 is compressed, causing the pressure value of the pressure sensor 103 to change. The pressure sensor 103 will send the data to the controller. The third hydraulic rod 17 drives the electric suction cup 22 to move downward to adsorb the bottle. After adsorption, it moves upward. The controller sends the data according to the pressure sensor 103. At this time, the bottom of the bottle is at the right end. The second motor 19 does not need to drive the adjusting frame 20 to rotate. Repeat the above subsequent steps to place the bottle on the conveyor belt 2. This is the whole working process of the continuous transfer device used for plastic bottle production.
