[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] like Figures 1 to 6 As shown, at least one embodiment provides a sorting and conveying device, comprising: a conveyor belt 1; the conveyor belt 1 is tilted, and the conveyor belt 1 is suitable for driving the leather cup 6 to move toward the supporting plate 5. The unloading end of the conveyor belt 1 is provided with a supporting plate 5, and the supporting plate 5 is tilted; after the leather cup 6 moves from the conveyor belt 1 to the supporting plate 5, under the action of its own gravity, the leather cup 6 slides on the supporting plate 5 toward the qualified product receiving box. A sorting cylinder 50 is provided on one side of the supporting plate 5, and the sorting cylinder 50 is parallel to the adjusting cylinder 28; wherein, if the leather cup 6 fails the inspection, the sorting cylinder 50 pushes the leather cup 6 to fall toward the recycling box. A limiting cylinder 51 is provided below the supporting plate 5, and a baffle 53 is provided at the end of the piston rod of the limiting cylinder 51, and the baffle 53 is suitable for limiting the moving direction of the leather cup 6. If the leather cup 6 fails the inspection, the limiting cylinder 51 drives the baffle 53 to move upward to limit the leather cup 6. At this time, the sorting cylinder 50 pushes the leather cup 6 to move and fall into the recycling box.

[0038] Reference Figure 1, an adjusting and sorting device 2 is slidably arranged on the conveyor belt 1 and is suitable for dividing the conveyor belt 1 into two conveying areas; the adjusting and sorting device 2 includes relatively arranged limit plates 29, the bottom wall of the limit plates 29 is in contact with the conveyor belt 1; and a detection component 20 is respectively arranged between the two limit plates 29; the detection component 20 is suitable for covering the open end of the leather cup 6, slowing down the movement speed of the leather cup 6, so that the leather cup 6 and the conveyor belt 1 move at a differential speed. Through the above method, dynamic detection of the leather cup 6 can be achieved, the conveyor belt 1 and the leather cup move at a differential speed, the conveyor belt 1 can clean the impurities at the bottom of the leather cup 6, so that the leather cup 6 can be placed more flatly on the conveyor belt 1, and the accuracy of the detection of the leather cup 6 is improved. Among them, the two limit plates 29 move horizontally along the surface of the conveyor belt 1, so that the leather cup 6 moves intermittently in the two conveying areas; the limit plates 29 are suitable for cleaning impurities on the surface of the conveyor belt 1 when moving horizontally. By adjusting the setting of the sorting device 2, the conveyor belt 1 is divided into two conveying areas. The limit plate 29 moves horizontally relative to the conveyor belt 1 so that the leather cup 6 moves intermittently in the two conveying areas. The limit plate 29 is suitable for cleaning impurities on the surface of the conveyor belt 1 when moving horizontally, so as to avoid impurities remaining on the surface of the conveyor belt 1 affecting the detection accuracy of the leather cup 6.

[0039] Reference Figure 2The detection component 20 includes: an upper clamping plate 21, which is vertically fixed on the inner wall of a limit plate 29; a lower clamping plate 22, which is lifted and lowered on the inner wall of another limit plate 29, and the lower clamping plate 22 is located below the upper clamping plate 21; the upper clamping plate 21 and the lower clamping plate 22 abut against each other, and are both parallel to the conveyor belt 1. When the conveyor belt 1 drives the leather cup 6 to move below the lower clamping plate 22, the upper clamping plate 21 moves toward the lower clamping plate 22 to push the lower clamping plate 22 to move downward, and the lower clamping plate 22 abuts against the open end of the leather cup 6 to seal the leather cup 6. At this time, the friction between the open end of the leather cup 6 and the lower pressing plate 22 increases. At the same time, the bottom wall of the leather cup 6 and the conveyor belt 1 are in a compressed state. The conveyor belt 1 continues to rotate to drive the leather cup 6 to move slowly on the bottom wall of the lower pressing plate 22. The air nozzle 3 delivers compressed air into the leather cup 6 to detect whether the air tightness of the leather cup 6 during the dynamic movement is qualified. Compared with the traditional static detection, that is, the leather cup 6 and the conveyor belt 1 remain stationary during the detection, and the air nozzle 3 delivers compressed air into the leather cup 6 to detect the air tightness of the leather cup 6. This embodiment adopts dynamic detection, that is, during the detection, the conveyor belt 1 drives the leather cup 6 to continue to move horizontally, the leather cup 6 moves relative to the lower pressing plate 22, and the air nozzle 3 delivers compressed air into the leather cup 6 to detect the air tightness of the leather cup 6. The dynamic detection of this embodiment can better ensure the air tightness of the leather cup 6 after the open end of the leather cup 6 abuts against the sealing member during actual use. When the two limit plates 29 move toward each other, the upper clamping plate 21 pushes the lower clamping plate 22 to move downward until the bottom wall of the lower clamping plate 22 abuts against the leather cup 6. When the two limit plates 29 move from one conveying area on the conveyor belt 1 to another conveying area, the bottom wall of the limit plate 29 fits the conveyor belt 1, which is suitable for cleaning the impurities remaining on the surface of the conveyor belt 1. The limit plates 29 move horizontally on the surface of the conveyor belt 1, and different leather cups 6 move alternately in different conveying areas of the conveyor belt 1. On the one hand, it can prevent the impurities on the bottom wall of the leather cup 6 from adhering and accumulating on the conveyor belt 1, and on the other hand, it also helps the limit plates 29 to clean the conveyor belt 1.

At this time, the bottom wall of the lower clamping plate 22 abuts against the open end of the leather cup 6 to achieve the effect of sealing the leather cup 6.

When the upper pressing plate 21 moves away from the lower pressing plate 22, the compression spring 26 pushes the lower pressing plate 22 to return upward.

[0042] Continue to refer to the attached Figure 3 The bottom wall of the lower pressing plate 22 is provided with a groove, and an air nozzle 3 and a pressure sensor 4 are arranged in the groove, and the air nozzle 3 faces the conveyor belt 1; wherein, the leather cup 6 abuts against the lower pressing plate 22 and moves to the bottom of the air nozzle 3, and the air nozzle 3 delivers compressed air into the leather cup 6, and the pressure sensor 4 is suitable for detecting whether the air tightness of the leather cup 6 is qualified. The air nozzle 3 is electrically connected to the pressure sensor 4, and after the leather cup 6 is sealed by the lower pressing plate 22, the air nozzle 3 delivers compressed air into the leather cup 6, and the pressure sensor 4 is suitable for detecting whether the pressure in the leather cup 6 reaches a preset value. If it reaches the standard, it means that the sealing of the leather cup 6 is qualified. If the pressure value is not reached, the sealing of the leather cup 6 is unqualified.
