[0017] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] The existing sorting equipment screws the plastic bottle caps onto the sealing tubes, immerses them in water, and observes whether bubbles are generated to determine whether the sealing performance is qualified. However, this detection method will cause residual moisture on the bottle caps, requiring additional subsequent processing, which increases costs.

[0019] To resolve this issue, see Figure 1-10 A sorting device for processing PET plastic bottle caps includes: a conveying mechanism 11, a support table 10 arranged at one end of the conveying mechanism 11, a clamping mechanism 50 arranged in a feed port 13 for clamping the bottle caps fed by the conveying mechanism 11, a detection component 14 arranged on a rotating table 12, a pressurizing mechanism 40 arranged on the rotating table 12 for injecting gas into a detection tube 16, and a pressing mechanism 20 arranged in the detection component 14 for driving the detection tube 16 to move downward.

[0020] Specifically, the support platform 10 is provided with a feed port 13, a detection component 14 is provided with a vertically downward moving groove 15, a detection tube 16 which can rotate along its own axis is penetrated in the moving groove 15, an air outlet 113 is provided at the bottom of the detection tube 16, an external thread 17 is provided on the outside of the detection tube 16, a rotary joint 18 is rotatably connected to the top of the detection tube 16, a sealing cover 19 is provided at the bottom of the detection tube 16, a top column 110 is fixedly provided at the bottom of the sealing cover 19, a first elastic member 111 is provided on the outside of the top column 110, and the end of the first elastic member 111 away from the top column 110 is fixedly connected to the outer bottom of the detection tube 16, and a material box 112 is fixedly provided at the bottom of the support platform 10.

[0021] When in use, the bottle cap is placed on the conveying mechanism 11 with the mouth facing upwards, and the bottle cap is driven to move toward the feed port 13 by the conveying mechanism 11. When a bottle cap moves into the feed port 13, the clamping mechanism 50 clamps and fixes the bottle cap so that it is located directly below the detection tube 16. The pressurizing mechanism 40 inflates the inner part of the pressing mechanism 20 to drive the pressing mechanism 20 to push the detection tube 16 downward until the lower end of the detection tube 16 contacts the bottle cap mouth. Since a swivel joint 18 is provided at the connection and the detection tube 16 can rotate, the external thread 17 of the detection tube 16 can be tightened with the bottle cap by rotating. When the bottle cap is continuously tightened with the external thread 17, , the gap between the bottle cap and the detection tube 16 will continue to decrease, and the bottle cap will contact the bottom of the top column 110. When the bottle cap continues to be tightened, the bottle cap and the sealing cover 19 will squeeze the first elastic member 111 in this process, and will push the top column 110 to form a relative upward displacement until it is completely tightened. At this time, there is a gap between the sealing cover 19 and the air outlet 113, that is, the air flow can pass through the air outlet 113 from the inside of the detection tube 16 and enter the bottle cap. After the inflation reaches a certain level, if the air pressure in the bottle cap remains unchanged, it indicates that the sealing of the bottle cap is good. If the air pressure in the bottle cap tends to decrease, it is determined that the bottle cap has a leakage problem. After the detection, the detection tube 16 is rotated in the opposite direction to separate the bottle cap from it, and the detected bottle cap is placed in the material box 112 for storage.

[0022] In addition, the material box 112 can be divided into two parts from the middle, one for qualified products and the other for defective products. And when the top column 110 is a single one, the diameter of the air outlet 113 opened at the bottom center of the detection tube 16 needs to be larger than the diameter of the top column 110, and the top column 110 is passed through the center of the air outlet 113, so that its top end is connected to the bottom center of the sealing cover 19. In order to ensure that the sealing cover 19 is always at the axis of the detection tube 16, the first elastic member 111 can be a conical spring, with the large end fixed to the edge of the air outlet 113 and the small end fixed to the edge of the top column 110. In this way, the rebound of the conical spring can ensure that the top column 110 is always located at the center of the air outlet 113. When there are two or more top columns 110, the top columns 110 can be distributed in a circular array at the bottom of the sealing cover 19, and the air outlet 113 can be set at the center position. The top column 110 does not pass through the air outlet 113. The first elastic member 111 can be an ordinary spring, which can be sleeved on the outside of the top column 110. This design can make it smoother when the sealing cover 19 is lifted up.

[0023] Among them, the rotary joint 18 is a prior art, which is used to connect the pipes so that the pipes can continue to rotate along their own axis after the connection. Fig.10 .

[0024] In the specific implementation process, Figure 1 and Figure 3 As shown, the pressing mechanism 20 includes a support frame 21 and a telescopic tube 22. The support frame 21 is fixedly arranged on the detection component 14. The telescopic tube 22 is fixedly arranged on the top of the support frame 21. The bottom of the telescopic tube 22 is fixedly connected to the top of the rotary joint 18. The telescopic tube 22 is connected to the pressurizing mechanism 40. A connecting plate 23 is fixedly arranged on the outer side of the bottom of the telescopic tube 22. A second elastic member 24 is fixedly arranged on the bottom of the connecting plate 23. The second elastic member 24 is fixedly connected to the upper end surface of the detection component 14 at one end away from the connecting plate 23.

[0025] When the downward pressing mechanism 20 is in use, the pressurizing mechanism 40 is required to pressurize the detection tube 16. The air outlet 113 at the bottom of the detection tube 16 is blocked by the sealing cover 19 and cannot release the pressure. Since the top of the telescopic tube 22 is fixed on the support frame 21 and cannot extend upward, when the internal air pressure continues to increase, the telescopic tube 22 can only gradually extend downward, and drive the connecting plate 23 to descend and squeeze the second elastic member 24. The elongation of the telescopic tube 22 can drive the detection tube 16 and its related structures to descend synchronously. Due to the elongation of the telescopic tube 22, the connecting plate 23 will tend to be pressed downward, and the downward pressure of the connecting plate 23 will generate an extrusion force on the second elastic member 24, driving the second elastic member 24 to deform. When the gas is withdrawn, the internal air pressure decreases, and the second elastic member 24 will generate a restoring deformation force, which will restore the telescopic tube 22 to its original compressed state while driving the detection tube 16 to rise, thereby realizing the control of the rise and fall of the detection tube 16.

[0026] In the specific implementation process, Figure 3 and Figure 4 As shown, it includes a rotating mechanism 30, which includes a gear column 31. The gear column 31 is fixedly arranged on the outer surface of the detection tube 16. A first motor 32 is fixedly arranged in the detection component 14. A main gear 33 is fixedly arranged at the output end of the first motor 32. The main gear 33 is meshed with the gear column 31.

[0027] When the bottom of the detection tube 16 contacts the bottle cap, the detection tube 16 needs to be rotated so that it can be tightened with the bottle cap through the external thread 17. When the detection tube 16 needs to be rotated, the first motor 32 is started, the first motor 32 drives the main gear 33 to rotate, the main gear 33 drives the gear column 31 to rotate, and the gear column 31 drives the detection tube 16 to rotate. By controlling the first motor 32, the purpose of controlling the rotation direction and speed of the detection tube 16 is achieved.

[0028] In addition, the gear column 31 can be designed as follows Figure 3 This design ensures that when the detection tube 16 drives the gear column 31 to descend, it can always maintain engagement with the main gear 33, so that the detection tube 16 can rotate while descending.

[0029] In the specific implementation process, Figure 2 and Figure 7As shown, the clamping mechanism 50 includes a slide groove 51 and a pair of connecting rods 54. The slide groove 51 is fixed with an electric push rod 52. An extrusion block 53 is slidably provided in the slide groove 51. The piston rod end of the electric push rod 52 is fixedly connected to the extrusion block 53. The pair of connecting rods 54 are hinged together from the middle to form a cross shape. A third elastic member 55 is fixed at the angle between the pair of connecting rods 54. A clamping block 56 is fixed at the same end of the connecting rods 54. The pair of clamping blocks 56 are symmetrically arranged. The pair of clamping blocks 56 are both located in the feed port 13. The other ends of the pair of connecting rods 54 are respectively pressed against the inclined surface of the extrusion block 53.

[0030] When the bottle cap is transported to the feed port 13 by the conveying mechanism 11, the electric push rod 52 is started, and the electric push rod 52 pushes the extrusion block 53 to move toward the connecting rod 54. The extrusion block 53 squeezes the end of the connecting rod 54. The connecting rod 54 is squeezed by the extrusion block 53, so that a pair of ends of the connecting rod 54 and the extrusion block 53 that are in contact with each other move together. The other end of the connecting rod 54 will also move together due to the hinge in the middle, and drive the clamping block 56 to move toward the middle, so as to clamp and fix the bottle cap.

[0031] In addition, a moving wheel can be provided at the joint between the connecting rod 54 and the extrusion block 53 , and fixed to the end of the connecting rod 54 , so as to ensure that the connecting rod 54 will not get stuck with the extrusion block 53 .

[0032] In the specific implementation process, Figure 1 and Figure 2 As shown, a rotating table 12 which can rotate along its own axis is arranged on the upper end surface of the supporting table 10, and a feed port 13 is opened on one side of the rotating table 12, and the feed port 13 runs through from top to bottom.

[0033] When in use, the rotating table 12 on the support table 10 allows the equipment thereon to rotate together, and the entire detection process is carried out during the rotation. The tested bottle caps can be placed into different material boxes 112 according to the detected structure during the rotation.

[0034] In the specific implementation process, Figure 5 As shown, a second motor 114 is fixedly disposed inside the support platform 10 , and an output end of the second motor 114 is fixedly connected to the bottom center of the rotating platform 12 .

[0035] When in use, the second motor 114 in the support platform 10 controls the rotating platform 12 on the support platform 10 to rotate, and the rotation direction and rotation speed of the rotating platform 12 are controlled by the second motor 114 .

[0036] In the specific implementation process, Figure 5 and Figure 6As shown, the gas pressurizing mechanism 40 includes a support column 41 and a pressurizing barrel 44. The support column 41 is fixedly arranged on the support platform 10. A threaded column 42 is fixedly arranged on the rotating platform 12. A piston plate 43 is fixedly arranged on the top of the threaded column 42. The bottom of the pressurizing barrel 44 is threadedly connected to the threaded column 42. The piston plate 43 is slidably connected in the pressurizing barrel 44. A T-shaped bar 45 is vertically fixedly arranged on the outside of the pressurizing barrel 44. The T-shaped bar 45 is slidably connected to the support column 41. At least one air supply pipe 46 is fixedly arranged on the pressurizing barrel 44. The air supply pipe 46 is connected to the telescopic tube 22 at one end away from the pressurizing barrel 44.

[0037] When the bottle caps are sorted, the second motor 114 drives the rotating table 12 to rotate, and the clamping mechanism 50 clamps and fixes the bottle caps so that they rotate together with the rotating table 12, and the detection and sorting are performed during the rotation. When the rotating table 12 rotates, the rotating table 12 drives the threaded column 42 to rotate, and the threaded column 42 drives the piston plate 43 to rotate. The pressurized barrel 44 cannot rotate due to the obstruction of the support column 41 and the T-shaped bar 45. The pressurized barrel 44 is threadedly connected to the threaded column 42, and the threaded column 42 is rotating, so that the pressurized barrel 44 moves downward due to the rotation of the threaded column 42. The pressurized barrel 44 descends while the height of the piston plate 43 remains unchanged, so that the piston plate 43 squeezes the air inside the pressurized barrel 44. The air in the pressurized barrel 44 is injected into the downward pressing mechanism 20 through the air supply pipe 46, so that it can drive the detection tube 16 to descend. When driving the detection component 14 to rotate, the detection component 14 stops when it rotates to the support column 41, and the pressurizing mechanism 40 stops pressurizing the detection tube 16, and determines whether it is a defective product by detecting the pressure change inside the detection tube 16. After the bottle cap is detected, the rotating table 12 drives it to rotate back. The pressurizing mechanism 40 will cause the piston plate 43 inside it to move away from the inner upper wall of the pressurizing barrel 44 due to the rotation of the rotating table 12, thereby forming a state similar to the withdrawal of a needle tube, thereby drawing the gas in the detection tube 16 back into the pressurizing barrel 44. When the pressing mechanism 20 drives the detection tube 16 to rise, and the bottle cap rises to the clamping mechanism 50, the clamping mechanism 50 fixes it again, and rotates the detection tube 16 in the opposite direction through the rotating mechanism 30 to unscrew the bottle cap, and when passing through the material box 112, the bottle cap is placed in the two boxes of the material box 112 according to the detection situation.

[0038] In the above solution, the sealing performance may be poor, and an auxiliary sealing ring may be provided on the outer side of the piston plate 43 to improve the sealing performance between the piston plate 43 and the pressurized barrel 44 .

[0039] In the specific implementation process, Figure 1 As shown, an air pressure sensor 47 is provided on the support frame 21 , and the air pressure sensor 47 is connected to the air supply pipe 46 .

[0040] When in use, when the air pressure sensor 47 detects the bottle caps, the pressure change in the detection tube 16 is detected by the air pressure sensor 47. When the air pressure sensor 47 detects that the air pressure in the detection tube 16 is continuously decreasing, it means that the bottle caps sorted at this time are defective and cannot be used. When the air pressure sensor 47 detects that the air pressure in the detection tube 16 remains unchanged, it means that the bottle caps sorted at this time are qualified products and can be used. According to the detection results of the air pressure sensor 47, the bottle caps with different detection results are respectively dropped into different material boxes 112 for separate storage.

[0041] In the specific implementation process, Figure 1 and Figure 8 As shown, it includes a deburring mechanism 60, which includes a shell 61. Cutters 62 are fixedly provided on the inner walls of the shell 61 on opposite sides. A groove 63 is provided on one side of the shell 61. A collecting drawer 64 is inserted into the bottom of one side of the shell 61. The distance between a pair of cutters 62 is the same as the size of the clinker bottle cap.

[0042] During use, after the bottle cap is tightened on the detection tube 16, the clamping mechanism 50 cancels the fixation of the bottle cap, and at this time, the pressing mechanism 20 will continue to pressurize the pressing mechanism 20 due to the continuous rotation of the rotating table 12, so that the pressing mechanism 20 continues to drive the detection tube 16 to continue to descend, and the pressing mechanism 20 will stop descending only when the rotating table 12 stops rotating, so that the detection tube 16 drives the bottle cap to descend below the clamping mechanism 50. In the process of inspecting the bottle cap, it will take some time to wait, and it is necessary to stop at the detection location for a period of time for inspection. When the bottle cap rotates to the detection location, the bottle cap is located between the sharpeners 62. During the inspection, the bottle cap can be rotated to produce a relative rotation with the sharpener 62, so as to achieve the purpose of removing the burrs on the outer side of the bottle cap, so that the burrs of the bottle cap can be removed at the same time during the sorting process, and the removed burrs fall into the collecting drawer 64 for collection, which is convenient for subsequent cleaning. The groove 63 prevents the bottle cap from being blocked when it is rotated into the shell 61.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
