[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 3 and Figure 5A sorting device for polyethylene bottle production and processing includes a conveyor belt 1. Visual inspection cameras 2 are installed on both the front and rear sides of the conveyor belt 1 for detecting polyethylene bottles with labels. The visual inspection cameras 2, typically referring to machine vision cameras, are specialized cameras used in industrial automation and inspection fields to replace human eyes for identification, measurement, positioning, and detection. They are not merely image acquisition devices but also the "eyes" of the entire machine vision system, their core task being to provide high-quality, stable, and reliable raw images for subsequent image processing software. A controller 3 is fixedly installed on the front of the conveyor belt 1, and the controller 3 is electrically connected to the visual inspection cameras 2. A transverse electric push rod 4 is fixedly installed on the front of the conveyor belt 1, and a push plate 5 located above the conveyor belt 1 is fixedly installed at the inner end of the output shaft of the transverse electric push rod 4. The visual inspection cameras 2 on both sides detect the outer wall of the polyethylene bottles. When the visual inspection camera 2 does not detect a label on the outer wall of the polyethylene bottle, the visual inspection camera 2 activates the power supply to the transverse electric push rod 4 via the controller 3. The extension of the output shaft of the transverse electric push rod 4 drives the push plate 5 to push the polyethylene bottle behind the conveyor belt 1. Limiting plates 6 are respectively set on the front and rear sides of the conveyor belt 1. Several balls 7 are rotatably connected to the inner side of the limiting plate 6. By rolling the balls 7 on the outer wall of the polyethylene bottle, the friction between the balls 7 and the contact surface of the polyethylene bottle is reduced, so that the polyethylene bottle with the label is discharged from the first discharge plate 12. The lower end of the balls 7 on the front and rear sides is fixedly installed with a telescopic rod 8 located below the conveyor belt 1. The end of the telescopic rod 8 away from the limiting plate 6 is movably sleeved with a sleeve 9. The inner side of the inner end of the telescopic rod 8 is provided with a movable component 10 for adjusting the position of the balls 7.

[0029] The conveyor belt 1 is connected to a drive device. When the conveyor belt 1 rotates, it drives the polyethylene bottle to be conveyed. The polyethylene bottle moves to the vision inspection camera 2. The lower end of the conveyor belt 1 is fixedly installed with a bracket 11. The right side of the conveyor belt 1 is fixedly connected with a first discharge plate 12. The back of the conveyor belt 1 is fixedly installed with a second discharge plate 13.

[0030] An inner plate 14 is fixedly installed on the upper surface of each limiting plate 6. A crossbar 15 is fixedly connected to the outer side of the inner plate 14 away from the limiting plate 6. A connecting plate 16 is fixedly installed on the outer end of the crossbar 15, and the connecting plate 16 is fixedly connected to the telescopic rod 8.

[0031] Please see Figure 2 , Figure 7 and Figure 9Several sliders 17 are evenly distributed on the outer wall of the inner end of the telescopic rod 8, and the end of the slider 17 away from the telescopic rod 8 is slidably connected to the inner wall of the sleeve 9. The movement of the slider 17 in the sleeve 9 restricts the movement path of the telescopic rod 8 in the sleeve 9. An outer side plate 18 is fixedly installed on the outer end of the telescopic rod 8, and the end of the outer side plate 18 away from the telescopic rod 8 is fixedly connected to the lower end face of the connecting plate 16.

[0032] A round rod 19 located on the right side of the telescopic rod 8 is fixedly installed on the inner side of the outer side plate 18. A connecting component 21 is fixedly installed on the end of the round rod 19 away from the telescopic rod 8. A sleeve rod 22 located outside the connecting component 21 is movably sleeved on the outer wall of the round rod 19, and the sleeve rod 22 is installed on the right side of the movable component 10.

[0033] A second spring 29 is fixedly installed on the left and right sides of the inner wall of the push plate 5. A movable plate 30 is fixedly connected to the end of the second spring 29 away from the push plate 5. Since the movable plate 30 is set with a slope that is lower in the front and higher in the back, the polyethylene bottle moves into the interior of the push plate 5. The second spring 29 connects the movable plate 30 and the push plate 5, so that the movable plates 30 on both sides can clamp the polyethylene bottle, which is convenient for the push plate 5 to clamp the polyethylene bottle. By moving the push plate 5, the polyethylene bottle can be pushed to the second discharge plate 13, and the polyethylene bottle without a label can be pushed out of the conveyor belt 1.

[0034] Please see Figure 4 , Figure 6 and Figure 8 The movable component 10 includes a ball nut 1001 and a ball screw 1002. The inner wall of the ball nut 1001 and the outer wall of the ball screw 1002 are connected by balls. Because the ball screw 1002 and the ball nut 1001 are connected by balls, the circumferential rotation of the ball screws 1002 on both sides simultaneously drives the ball nut 1001 to rotate. Simultaneously, the rotation of the ball nuts 1001 on both sides, through the connection of the outer outer plate 18, connecting plate 16, crossbar 15, and inner plate 14, drives the front and rear limiting plates 6 to move towards the polyethylene bottle. The ball bearing 7 contacts the outer wall of the polyethylene bottle. The outer wall of the ball bearing nut 1001 is fixedly connected to the inner wall of the telescopic rod 8. A rotating assembly 23 is fixedly installed at the inner end of the ball screw 1002. A rotary motor 24 is fixedly connected to the lower end of the rotating assembly 23. A housing 25 is fixedly sleeved on the outer wall of the rotary motor 24. A protective shell 26 located outside the rotating assembly 23 is fixedly installed at the upper end of the housing 25. A support rod 27 is fixedly installed on the right side of the protective shell 26. A fixing block 28 is fixedly connected to the end of the support rod 27 away from the protective shell 26, and the outer wall of the fixing block 28 is fixedly connected to the sleeve rod 22.

[0035] The connecting assembly 21 includes a disc 211 and a first spring 212. The outer side of the disc 211 is fixedly connected to the round rod 19, and the inner side of the disc 211 is fixedly connected to the outer end of the first spring 212. The disc 211 is configured to connect the round rod 19 and the first spring 212. The end of the first spring 212 away from the disc 211 is fixedly connected to the inner wall of the sleeve rod 22. The first spring 212 is configured to connect the disc 211 and the sleeve rod 22.

[0036] The rotating assembly 23 includes a first bevel gear 231 and a second bevel gear 232. The outer wall of the second bevel gear 232 meshes with the outer wall of the first bevel gear 231. When the rotary motor 24 is turned on, it drives the second bevel gear 232 to rotate. Since the second bevel gear 232 and the first bevel gear 231 are connected by meshing, the rotation of the second bevel gear 232 drives the first bevel gears 231 on both sides to rotate simultaneously. The rotation of the first bevel gears 231 on both sides drives the rotation of the ball screw 1002. The outer side of the first bevel gear 231 is fixedly connected to the ball screw 1002. The lower end of the second bevel gear 232 is fixedly connected to the upper end of the output shaft of the rotary motor 24.

[0037] Working principle: In use, firstly, adjust the distance between the limiting plates 6 on both the front and rear sides according to the actual size of the polyethylene bottle, and turn on the power of the rotary motor 24. After the rotary motor 24 is turned on, it drives the rotation of the second bevel gear 232. Since the second bevel gear 232 and the first bevel gear 231 are connected by meshing, the rotation of the second bevel gear 232 drives the rotation of the first bevel gears 231 on both sides. The rotation of the first bevel gears 231 on both sides drives the rotation of the ball screw 1002. Since the ball screw 1002 and the ball nut 1001 are connected by the movable ball, the circumferential rotation of the ball screw 1002 on both sides drives the rotation of the ball nut 1001 on both sides. As the ball nuts 1001 on both sides rotate, they drive the limiting plates 6 on both sides to move towards the polyethylene bottle through the connection of the outer plate 18, connecting plate 16, crossbar 15, and inner plate 14 until the ball 7 contacts the outer wall of the polyethylene bottle. Then, turn on the external power supply of the conveyor belt 1. The conveyor belt 1 rotates simultaneously with the first bevel gear 232. The conveyor belt 1 is used to transport polyethylene bottles. When a polyethylene bottle moves to the vision inspection camera 2, the vision inspection cameras 2 on both the front and rear sides inspect the outer wall of the polyethylene bottle. When the vision inspection camera 2 does not detect the label on the outer wall of the polyethylene bottle, the vision inspection camera 2 turns on the power of the transverse electric push rod 4 through the controller 3. The extension of the output shaft of the transverse electric push rod 4 drives the push plate 5 to move towards the polyethylene bottle and towards the second discharge plate 13. Since the moving plate 30 is set with a slope that is lower in the front and higher in the back, the polyethylene bottle moves into the interior of the push plate 5. The second spring 29 connects the moving plate 30 and the push plate 5, so that the moving plates 30 on both sides can clamp the polyethylene bottle, which is convenient for the push plate 5 to clamp the polyethylene bottle. The movement of the push plate 5 can push the polyethylene bottle to the second discharge plate 13, and the polyethylene bottle without a label can be pushed out of the conveyor belt 1. Finally, the rolling of the ball bearing 7 on the outer wall of the polyethylene bottle reduces the friction between the ball bearing 7 and the contact surface of the polyethylene bottle, so that the polyethylene bottle with a label can be discharged from the first discharge plate 12.
