[0033] When the belt conveying assembly 2 swings left and right under the action of external force, support frame 3 can swing synchronously and drive rotating platform 4 to rotate, at this moment, swing lever 52 immediately swings along cam plate 51, because rotating platform 4, cam swing part 5 are located at different height positions, thus, through the cooperation of rotating platform 4, cam swing part 5, fixed frame 1 can provide two support points for support frame 3 to swing left and right, and further improve the stability of support frame 3 to swing left and right along fixed frame 1, and in the process of swing lever 52 swinging, swing lever 52 always maintains the same swing direction as the belt conveying assembly 2, thus, spring 53 can always provide support force along the conveying direction of the belt conveying assembly 2.

[0034] In the prior art, the belt conveying assembly 2 also needs to swing in the up-down direction, thus, one end of the belt conveying assembly 2 needs to be pivotally connected with the support frame 3, and the other end is suspended and can swing up and down. In the process of the belt conveying assembly 2 swinging up and down, the bearing force at the pivot connection position between the belt conveying assembly 2 and the support frame 3 is large, thus, in the cam swing part 5, through the cooperation of spring 53 and swing lever 52, support force along the arrangement direction of the belt conveying assembly 2 can be applied to the support frame 3, and further the structural strength of the support frame 3 in the arrangement direction of the belt conveying assembly 2 is enhanced, so as to ensure the stability of the belt conveying assembly 2 swinging up and down.

[0035] It should be noted that the cam plate 51 is a plate body with one end fixedly connected to the fixed frame 1 and the other end provided with a circular-arc convex surface, and the axis of the circular-arc convex surface coincides with the axis of the rotating platform 4.

[0036] In some embodiments, referring to the drawings Figures 3-4As shown, the swing lever 52 comprises a lever body 521, an arc swing plate 522, and a roller 523.

The two ends of the arc swing plate 522 are symmetrically provided with the rollers 523 which abut against the cam plate 51. When the support frame 3 swings left and right, the rollers 523 on the arc swing plate 522 can roll along the arc convex surface, so that the swing lever 52 and the spring 53 are always kept parallel to the belt conveying assembly 2, thereby enhancing the supporting force on the belt conveying assembly 2.

[0037] Further, one end of the lever body 521 away from the arc swing plate 522 is arranged through the support frame 3, and the sidewall of the other end is integrally provided with a lever body boss 5211 for abutting against the spring 53.

[0038] In some embodiments, referring to the accompanying drawings, Figures 2-3 As shown, the support frame 3 comprises a stand 31 and a triangular frame 32. The stand 31 is vertically arranged, and the upper end thereof is connected to the rotating platform 4, and the lower end thereof is connected to the triangular frame 32. The lower end of the triangular frame 32 is integrally provided with a sleeve 33 for the swing lever 52 to pass through. By arranging the triangular frame 32, the overall structural strength of the support frame 3 can be enhanced by the structural feature of the triangle.

Specifically, the lifting drive 6 is arranged in an inclined direction, and the cylinder body thereof is pivotally connected to the triangular frame 32, and the piston rod thereof is pivotally connected to the belt conveying assembly 2. Exemplarily, the lifting drive 6 can be a linear drive such as a pneumatic cylinder or an electric cylinder. By arranging the lifting drive 6, the up-and-down swing of the belt conveying assembly 2 is realized. By connecting the lifting drive 6 to the support frame 3, the support of the lifting drive 6 can be enhanced by the supporting force of the support frame 3 along the conveying direction of the belt conveying assembly 2, thereby ensuring the stability of the up-and-down swing of the belt conveying assembly 2.

[0041] In some embodiments, referring to the accompanying drawings, Figure 3 As shown, the fixed frame 1 is symmetrically provided with limiting baffles 11 on both sides of the stand 31, so as to limit the swing range of the stand 31, and further limit the swing range of the belt conveying assembly 2.

[0042] In actual application, when the belt conveying assembly 2 swings left and right to the set position, the belt conveying assembly 2 can convey the goods, and the swing position of the belt conveying assembly 2 should be fixed during the conveying of the goods.
