The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] For examples, see Figure 1-6 In an embodiment of the present invention, a feeding mechanism for processing plastic bottle caps includes a base 1, a deodorizing mechanism 2 is fixedly connected to the left end of the upper surface of the base 1, a downwardly inclined guide plate 3 is installed at the right end of the deodorizing mechanism 2, the plastic bottle caps are transported from left to right by the guide plate 3, a vibration motor is arranged on the lower surface of the guide plate 3, the energy brought by vibration facilitates the movement of the plastic bottle caps, a discharging mechanism 4 is installed on the right end of the lower surface of the guide plate 3, and a conveyor 5 is fixedly connected to the right end of the upper surface of the base 1, and the plastic bottle caps are transported to the designated position by the conveyor 5.

[0027] The deodorizing mechanism 2 comprises a cleaning box 21 fixedly connected to the left end of the upper surface of the base 1. Four partitions 22 are installed equidistantly from left to right at the bottom of the inner cavity of the cleaning box 21. The partitions 22 are used to divide the cleaning box 21 into three plastic bottle cap processing areas. Two water tanks 23 are installed side by side on the lower surface of the cleaning box 21. A valve 24 is installed at the bottom of the water tank 23. A pickling nozzle 25, a cleaning nozzle 26 and an air knife 27 are installed in the inner cavity of the cleaning box 21 from left to right. The pickling nozzle 25 is used to spray pickling liquid to remove the odor of the plastic bottle caps by acid. The cleaning nozzle 26 sprays clean water outward to remove the pickling liquid on the surface of the plastic bottle caps. The air knife 27 is externally connected to a hot air blower to blow out Hot air is used to dry the plastic bottle caps. A limiting mechanism 28 is installed on the top of the cleaning box 21. Support plates 29 are installed horizontally on the front and rear inner walls of the cleaning box 21. Guide rollers 210 that can rotate around their own axes are installed on the left and right ends of the inner side of the support plate 29 through bearings. A mesh conveyor belt 211 is sleeved on the outer wall of the guide roller 210. The mesh conveyor belt 211 is made of corrosion-resistant material to prevent the mesh conveyor belt 211 from being corroded by the pickling solution. A motor 212 is installed on the front side of the support plate 29 on the front side, and the motor 212 is connected to one of the guide rollers 210. When the motor 212 drives the guide roller 210 to rotate clockwise, the plastic bottle caps are transported from left to right through the mesh conveyor belt 211.

[0028] Plastic bottle cap cleaning: the plastic bottle caps are placed on the mesh conveyor belt 211, and the guide roller 210 is driven by the motor 212 to rotate clockwise. The mesh conveyor belt 211 conveys the plastic bottle caps from left to right. When passing through the pickling nozzle 25, the pickling nozzle 25 sprays pickling liquid upward, and the pickling liquid removes the plastic odor of the plastic bottle caps. When passing through the cleaning nozzle 26, the cleaning nozzle 26 sprays clean water to the plastic bottle caps to rinse the plastic bottle caps and remove the pickling liquid on the surface. When passing through the wind knife 27, the wind knife 27 blows hot air to the plastic bottle caps to dry them. Then the guide plate 3 uses its own inclined surface to convey the plastic bottle caps from left to right. The discharging mechanism 4 allows the plastic bottle caps to come out individually and orderly. Finally, the conveyor 5 completes the conveying and loading of the plastic bottle caps.

When the lead screw 283 rotates clockwise or counterclockwise, the moving plate 284 is driven to the left or right by the threaded rotation force of the lead screw 283. Movement, guide grooves 285 are provided on the left and right sides of the front of the movable plate 284, and lifting rods 286 that can slide up and down are inserted on the left and right sides of the top plate 281. A pin 287 inserted into the guide groove 285 is installed on the top of the lifting rod 286, and a limiting mesh plate 288 is installed on the bottom of the lifting rod 286. The two guide grooves 285 are arranged on the outer wall of the movable plate 284 at an angle downward from left to right. When the movable plate 284 moves left and right, the inclined surface of the guide groove 285 can squeeze the pin 287 downward or upward, thereby realizing that the limiting mesh plate 288 is close to or away from the mesh conveyor belt 211.

[0030] Cleaning of plastic bottle caps of different thicknesses: driving the lead screw 283 to rotate clockwise or counterclockwise, the threaded rotation force of the lead screw 283 pulls the movable plate 284 to move to the left or right, the inclined surface of the guide groove 285 squeezes the pin 287 downward or upward, allowing the limiting mesh plate 288 to move downward or upward, and the distance between the limiting mesh plate 288 and the mesh conveyor belt 211 becomes smaller or larger. The limiting mesh plate 288 prevents the plastic bottle caps on the mesh conveyor belt 211 from tipping over, thereby achieving cleaning of plastic bottle caps of different thicknesses.

[0031] Furthermore, the discharging mechanism 4 includes a slide plate 41 fixedly connected to the right end of the lower surface of the guide plate 3. The slide plate 41 is parallel to the upper surface of the guide plate 3, so that the plastic bottle caps can be smoothly transferred from the guide plate 3 to the slide plate 41. Two rotating shafts 42 that can rotate around their own axes are installed through bearings on the left ends of the front and rear sides of the top of the slide plate 41. A gear 43 is installed at the bottom of the rotating shaft 42. A baffle 44 is installed on the outer wall of the rotating shaft 42. The baffle 44 is located at the top of the slide plate 41. The plastic bottle caps are blocked and limited by the two baffles 44. The left end of the lower surface of the slide plate 41 is fixed A box body 45 is connected, a screw rod 46 is screwed on the left side of the box body 45, a driving plate 47 that can slide left and right is inserted into the inner cavity of the box body 45, the left end of the driving plate 47 is connected to the right end of the screw rod 46 through a bearing, when the screw rod 46 rotates clockwise or counterclockwise, the screw rod 46 can pull the driving plate 47 to move to the left or right, and a plurality of teeth 48 are installed on the front and rear sides of the driving plate 47 from left to right, and the teeth 48 are meshed and connected with the gear 43, and the two baffles 44 can be moved inward or outward at the same time through the transmission of the teeth 48 and the gear 43.

[0032] Plastic bottle cap discharging: The distance between the two baffles 44 forms a plastic bottle cap moving channel, so that the plastic bottle caps can be discharged one by one in an orderly manner.

[0033] When it is necessary to feed plastic bottle caps of different sizes, the screw rod 46 is rotated clockwise or counterclockwise to allow the screw rod 46 to pull the driving plate 47 to move to the left or right, and the two rotating shafts 42 rotate in opposite directions under the transmission of the teeth 48 and the gear 43, so that the two baffles 44 swing inward or outward at the same time, and the distance between the two baffles 44 becomes smaller or larger. The position is limited according to the outer diameter of the plastic bottle cap, so as to achieve the feeding of plastic bottle caps with different outer diameters.

[0034] The workflow is as follows: Step 1, placing the plastic bottle caps on the mesh conveyor belt 211, driving the guide roller 210 to rotate clockwise through the motor 212, allowing the mesh conveyor belt 211 to convey the plastic bottle caps from left to right, passing through the pickling nozzle 25, the pickling nozzle 25 sprays pickling solution upward, and the pickling solution removes the plastic odor of the plastic bottle caps, passing through the cleaning nozzle 26, the cleaning nozzle 26 sprays clean water to the plastic bottle caps, rinses the plastic bottle caps, and removes the pickling solution on the surface, and when passing through the wind knife 27, the wind knife 27 blows hot air to the plastic bottle caps to dry them, and then the guide plate 3 uses its own inclined surface to convey the plastic bottle caps from left to right, and when arriving on the slide plate 41, the distance between the two baffles 44 is used to make the plastic bottle caps come out individually and orderly, and finally the conveying and loading of the plastic bottle caps is completed through the conveyor 5; Step 2: When it is necessary to clean the plastic bottle caps of different thicknesses, the screw 283 is driven to rotate clockwise or counterclockwise, and the screw thread rotation force of the screw 283 pulls the movable plate 284 to move leftward or rightward, and the inclined surface of the guide groove 285 presses the pin 287 downward or upward, so that the limiting mesh plate 288 moves downward or upward, and the distance between the limiting mesh plate 288 and the mesh conveyor belt 211 becomes smaller or larger. The limiting mesh plate 288 prevents the plastic bottle caps on the mesh conveyor belt 211 from tipping over, so as to achieve cleaning of plastic bottle caps of different thicknesses; Step three, when it is necessary to feed plastic bottle caps of different sizes, rotate the screw 46 clockwise or counterclockwise to allow the screw 46 to pull the drive plate 47 to move to the left or right, and the two shafts 42 rotate in opposite directions under the transmission of the teeth 48 and the gear 43, so that the two baffles 44 swing inward or outward at the same time, and the distance between the two baffles 44 becomes smaller or larger. The position is limited according to the outer diameter of the plastic bottle caps to achieve the feeding of plastic bottle caps with different outer diameters.
