The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0026] Example 1

[0027] Reference Figures 1 to 6 The automatic sorting device for plastic bottle caps described in the embodiment comprises a guard 1, the guard 1 is composed of two side plates 11 and a front guard 12, the two side plates 11 are parallel to each other, the front guard 12 is fixedly connected with one side plate 11 on each side, a support assembly 3 is installed between the two side plates 11, a conveyor belt 4 is attached to the support assembly 3, a plurality of lifting strips 5 are installed on the conveyor belt 4, an adjusting assembly 2 for adjusting the support assembly 3 to be close to or away from the front guard 12 is installed on each side plate 11, and the support assembly 3 is fixedly connected with one adjusting assembly 2 on each side.

[0028] Specifically, the support assembly 3 comprises a plurality of curved plates 31 and a plurality of connecting rods 32, the plurality of curved plates 31 are fixedly connected through the connecting rods 32, one side of the curved plate 31 facing the front guard 12 is a concave-convex smooth curved surface, and the conveyor belt 4 slides on the curved surface of the curved plate 31.

[0029] The conveyor belt 4 is driven to convey from bottom to top by a driving device.

[0030] Preferably, the plurality of lifting strips 5 are equidistantly installed on one side of the conveyor belt 4 close to the front guard 12.

[0031] It is worth noting that the width of the lifting strip 5 is not greater than the thickness of the bottle cap, that is, the width of the lifting strip 5 is extremely small, the actual curved surface curvature is small, and the lifting strip 5 is always in a horizontal state visible to the naked eye.

[0032] The conveyor belt 4 drives the lifting strip 5 to convey the bottle cap upward from bottom to top, due to the characteristics of the bottle cap, that is, the front surface is empty and the back surface is solid, and the weight difference between the front and back surfaces, when the back surface of the bottle cap is close to the front guard 12, when it is conveyed to the convex part of the curved plate 31, the center of gravity of the bottle cap crosses the lifting strip 5, and the bottle cap naturally falls off, when the back surface of the bottle cap is tightly attached to the conveyor belt 12, the center of gravity of the bottle cap is always located on the lifting strip 5, and the bottle cap is lifted up, realizing the sorting of the front and back surfaces.

[0033] The adjusting assembly comprises a fan-shaped cover plate 21 and a shoulder 26 fixedly connected with the connecting rod 32 / curved plate 31 side end, the shoulder 26 is provided with an adjusting rod 28, the cover plate 21 is rotatably installed on the side plate 11 around the rotating shaft 22, and the adjusting slot 27 is formed through the cover plate 21 and the side plate 11, the adjusting rod 28 is slidably connected with the inner wall of the adjusting slot 27, and a plurality of adjusting holes 23 along the arc edge of the cover plate 21 are formed on the side plate 11 at equal intervals, and the cover plate 21 is fixedly connected with the side plate 11 by inserting the pin shaft 25 into the adjusting hole 23.

[0034] The adjusting slot 27 is an inclined through hole.

[0035] Preferably, the handle 24 is further installed on the cover plate 21.

[0036] Before work, the support assembly 3 is adjusted to a suitable position by the adjusting assembly 2, so that the tension of the conveying belt 4 adapts to different bottle caps. Specifically, the pin shaft 25 is pulled out of the adjusting hole 23, the handle 24 is held to rotate the cover plate 21 upwards or downwards around the rotating shaft 22, because the adjusting slot 27 is inclined, the shoulder 26 is driven by the adjusting slot 27 to approach or move away from the front guard plate 12, so that the curved plate 31 approaches or moves away from the front guard plate 12, when the curved plate 31 approaches the front guard plate 12, the conveying belt 4 is taut, and the camber is increased, when the curved plate 31 moves away from the front guard plate 12, the conveying belt 4 is relaxed, and the camber is reduced, so as to adapt to different types of bottle caps.
