[0060] It is found through research that in the related art, the skin bowl needs to be detected after being formed to ensure that its sealing performance meets the standard.

[0061] In the related art, in the current skin bowl airtightness detection process, the sorting and conveying equipment generally adopts a combination scheme of a fixed dust removal module (such as a brush cleaning, negative pressure adsorption) and a static detection process.

[0062] However, the traditional dust removal equipment needs to stop the conveying belt to clean the surface of the conveying belt, and cannot remove impurities in real time during the continuous movement of the skin bowl; at the same time, when detecting the airtightness of the skin bowl, the skin bowl needs to be kept in a stationary state, and the continuous movement of the conveying belt driven by the skin bowl conflicts with the static detection process, and the static detection data may not truly reflect the sealing performance of the skin bowl in the actual use process.

[0063] Therefore, the present application mainly provides a way of differential dust removal to improve the accuracy of airtightness detection.

[0064] The defects of the above scheme and the causes thereof are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the present disclosure to the above problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.

[0065] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0066] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0067] As Figures 1 to 6As shown, at least one embodiment provides a sorting conveying device, comprising: a conveying belt 1; the conveying belt 1 is arranged obliquely, and the conveying belt 1 is suitable for driving the leather bowl 6 to move to the direction of the supporting plate 5. The lower end of the conveying belt 1 is provided with the supporting plate 5, and the supporting plate 5 is arranged obliquely; after the leather bowl 6 moves from the conveying belt 1 to the supporting plate 5, under the action of its own gravity, the leather bowl 6 slides on the supporting plate 5 to the qualified product collecting box. One side of the supporting plate 5 is provided with a sorting cylinder 50, and the sorting cylinder 50 is parallel to the adjusting cylinder 28; wherein, if the leather bowl 6 is unqualified, the sorting cylinder 50 pushes the leather bowl 6 to fall into the recycling box. A limiting cylinder 51 is arranged below the supporting plate 5, and a baffle 53 is arranged 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 bowl 6. If the leather bowl 6 is unqualified, the limiting cylinder 51 drives the baffle 53 to move upward to limit the leather bowl 6, and at this time the sorting cylinder 50 pushes the leather bowl 6 to move to fall into the recycling box.

[0068] Reference is made to the accompanying drawings Figure 1 The adjusting and sorting device 2 is arranged slidingly on the conveying belt 1, and is suitable for dividing the conveying belt 1 into two conveying areas; the adjusting and sorting device 2 comprises oppositely arranged limiting plates 29, and the bottom walls of the limiting plates 29 are attached to the conveying belt 1; and a detection assembly 20 is arranged between the two limiting plates 29 respectively; the detection assembly 20 is suitable for covering the open end of the leather bowl 6, slows down the moving speed of the leather bowl 6, so that the leather bowl 6 moves at a different speed from the conveying belt 1. In the above manner, dynamic detection of the leather bowl 6 can be realized, the conveying belt 1 and the leather bowl move at different speeds, the conveying belt 1 can clean the impurities at the bottom of the leather bowl 6, so that the leather bowl 6 can be placed more flatly above the conveying belt 1, and the accuracy of detection of the leather bowl 6 is improved. Among them, the two limiting plates 29 move horizontally along the surface of the conveying belt 1, so that the leather bowl 6 moves intermittently in the two conveying areas; the limiting plate 29 is suitable for cleaning the impurities on the surface of the conveying belt 1 when moving horizontally. By arranging the adjusting and sorting device 2, the conveying belt 1 is divided into two conveying areas, the limiting plate 29 moves horizontally relative to the conveying belt 1, so that the leather bowl 6 moves intermittently in the two conveying areas, and the limiting plate 29 is suitable for cleaning the impurities on the surface of the conveying belt 1 when moving horizontally; so as to avoid that the impurities remaining on the surface of the conveying belt 1 affect the detection accuracy of the leather bowl 6.

[0069] Reference is made to the accompanying drawings Figure 2, the detection assembly 20 comprises: an upper pressing plate 21 vertically fixed on the inner side wall of one limiting plate 29; a lower pressing plate 22 vertically fixed on the inner side wall of another limiting plate 29, and the lower pressing plate 22 is below the upper pressing plate 21; the upper pressing plate 21 and the lower pressing plate 22 are in abutment with each other and are parallel to the conveying belt 1, when the conveying belt 1 drives the rubber bowl 6 to move below the lower pressing plate 22, the upper pressing plate 21 moves to the direction of the lower pressing plate 22 to push the lower pressing plate 22 to move downward, and the lower pressing plate 22 is in abutment with the opening end of the rubber bowl 6 to seal the rubber bowl 6. At this time, the friction between the opening end of the rubber bowl 6 and the lower pressing plate 22 increases, and the rubber bowl 6 and the conveying belt 1 are in a pressing state. The conveying belt 1 continues to rotate to drive the rubber bowl 6 to move slowly at the bottom wall of the lower pressing plate 22; the air nozzle 3 sends compressed air into the rubber bowl 6 to detect whether the air tightness of the rubber bowl 6 in the dynamic moving process is qualified. Compared with the traditional static detection, that is, when detecting, the rubber bowl 6 and the conveying belt 1 are kept in a static state, the air nozzle 3 sends compressed air into the rubber bowl 6 to detect the air tightness of the rubber bowl 6. The embodiment adopts dynamic detection, that is, when detecting, the conveying belt 1 drives the rubber bowl 6 to continue to move horizontally, the rubber bowl 6 moves relative to the lower pressing plate 22, and the air nozzle 3 sends compressed air into the rubber bowl 6 to detect the air tightness of the rubber bowl 6. The dynamic detection of the embodiment can better ensure the air tightness of the rubber bowl 6 after the opening end of the rubber bowl 6 is in abutment with the sealing element in the actual use process. When the two limiting plates 29 move towards each other, the upper pressing plate 21 pushes the lower pressing plate 22 to move downward, and the bottom wall of the lower pressing plate 22 is in abutment with the rubber bowl 6. When the two limiting plates 29 move from one conveying area on the conveying belt 1 to another conveying area, the bottom wall of the limiting plate 29 is in abutment with the conveying belt 1, which is suitable for cleaning the impurities remaining on the surface of the conveying belt 1. By moving the limiting plate 29 horizontally on the surface of the conveying belt 1 and making different rubber bowls 6 move in different conveying areas of the conveying belt 1, on the one hand, the impurities adhered and accumulated on the bottom wall of the rubber bowl 6 can be avoided to be adhered and accumulated on the conveying belt 1, and on the other hand, the limiting plate 29 can also help to clean the conveying belt 1. Figure 5 and Figure 6 The arrow in the figure indicates the horizontal moving direction of the limiting plate 29.

When the two limiting plates 29 move towards each other, the upper pressing plate 21 and the lower pressing plate 22 move towards each other, and the inclined surface 24 pushes the guide block 23 to make the lower pressing plate 22 move downward. At this time, the bottom wall of the lower pressing plate 22 is in abutment with the opening end of the rubber bowl 6 to achieve the effect of sealing the rubber bowl 6.

[0071] Referring to the accompanying drawings, Figure 3In order to improve the stability of the lifting movement of the lower pressing plate 22, the side wall of the limiting plate 29 is provided with a positioning plate 25, and the lower pressing plate 22 is slidingly arranged on the side wall of the positioning plate 25. A plurality of compression springs 26 are arranged on the upper and lower surfaces of the lower pressing plate 22 respectively, and one end of the compression spring 26 is arranged on the side wall of the positioning plate 25. 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 move upwardly.

[0072] With reference to the accompanying drawings Figure 3 The bottom wall of the lower pressing plate 22 is provided with a groove, and a gas nozzle 3 and a pressure sensor 4 are arranged in the groove. The gas nozzle 3 faces the conveying belt 1. The skin bowl 6 abuts against the lower pressing plate 22 and moves below the gas nozzle 3. The gas nozzle 3 delivers compressed air into the skin bowl 6. The pressure sensor 4 is adapted to detect whether the air tightness of the skin bowl 6 is qualified. The gas nozzle 3 is electrically connected with the pressure sensor 4. After the skin bowl 6 is sealed by the lower pressing plate 22, the gas nozzle 3 delivers compressed air into the skin bowl 6. The pressure sensor 4 is adapted to detect whether the pressure in the skin bowl 6 reaches a preset value. If the pressure value reaches the preset value, it means that the skin bowl 6 is qualified. If the pressure value does not reach the preset value, it means that the skin bowl 6 is unqualified.

There are four adjusting cylinders 28. Two adjusting cylinders 28 are arranged on one side of one limiting plate 29. The adjusting cylinders 28 are adapted to drive the two limiting plates 29 to move relative to the conveying belt 1.
