DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0025] like Figure 1 As shown, this embodiment provides a suction edge air duct with an air volume adjustment function, including a suction edge air duct 2, at the end of which an air volume adjustment component is arranged, the air volume adjustment component includes an air duct sleeve 1, an air volume adjustment plate 3 and a rolling member 4, the air duct sleeve 1 is sleeved on the end of the suction edge air duct 2 and is connected to the suction edge air duct 2, the air volume adjustment plate 3 is used to adjust the area of ​​the suction pipe opening, and the rolling member 4 reduces the friction force generated by the contact between the aluminum waste edge and the pipe wall during suction, so as to avoid the breakage of the aluminum waste edge.

[0026] like Figure 2 As shown, the air volume adjustment plate 3 is rotatably connected to the outer end surface of the air duct sleeve 1, and the air volume adjustment plate 3 partially covers the air duct sleeve 1. By rotating the air volume adjustment plate 3, the ventilation area of ​​the air duct sleeve 1 can be adjusted, thereby controlling the suction force of the suction side air duct 2.

[0027] As an implementation method, the air duct sleeve 1 is cylindrical on the outside, the air volume adjustment plate 3 is arched, and the air volume adjustment plate 3 is arranged concentrically with the air duct sleeve 1. Fasteners and limit blocks 11 are respectively arranged on the outer end surface of the air duct sleeve 1 and along the chord length direction of the air volume adjustment plate 3. The fasteners fix the air volume adjustment plate 3 on the air duct sleeve 1, and the limit block 11 limits the initial rotation position of the air volume adjustment plate 3.

[0028] Specifically, the fastener is a screw, and the air volume adjustment plate 3 is fixed to the air duct sleeve 1 by the screw. By loosening the screw, the opening and closing angle of the air volume adjustment plate 3 can be adjusted, and by tightening the screw, the air volume adjustment plate 3 can be fixed. The limit stopper 11 is a rectangular plate. The height of the limit stopper 11 is equal to the thickness of the air volume adjustment plate 3, and the width of the limit stopper 11 is equal to the wall thickness of the air duct sleeve 1.

[0029] When the air volume adjustment plate 3 is located at the initial rotation position, the ventilation area of ​​the air duct sleeve 1 is the smallest and the suction force is the largest.

[0030] Preferably, two air volume adjustment plates 3 are disposed on the outer end surface of the air duct sleeve 1 , and the two air volume adjustment plates 3 are symmetrical along the center point of the air duct sleeve 1 .

[0031] like Figure 3 As shown, the rolling element 4 rotates in the air duct sleeve 1. Specifically, the rolling element 4 includes a rotating shaft and a rolling sleeve, the two ends of the rotating shaft are fixedly connected to the tube wall of the air duct sleeve 1, and the rolling sleeve is sleeved on the rotating shaft, and the rolling sleeve rotates relative to the rotating shaft. After the material enters the air duct sleeve 1, the tail end of the material enters the suction side air duct 2 along the tangent of the rolling sleeve as the rolling sleeve rotates, reducing the friction when the material is sucked and avoiding material breakage.

[0032] The middle of the rolling sleeve is concave relative to the two ends, so that the waste edge is close to the center of the pipeline. The rolling sleeve is preferably made of 304 stainless steel to increase wear resistance. In order to avoid axial displacement of the rolling sleeve, positioning sleeves can be set at both ends of the rolling sleeve, and the positioning sleeves are fixedly connected to the air duct sleeve 1.

[0033] As an implementation method, Figure 4 As shown, two rolling members are symmetrically arranged in the radial direction inside the air duct sleeve 1, a first rolling sleeve 41 is arranged on the first rolling member, and a second rolling sleeve 42 is arranged on the second rolling member, the first rolling sleeve 41 and the second rolling sleeve 42 are connected to the air duct sleeve 1 in the same manner, the cross-section of the first rolling sleeve 41 is in the shape of an "I", the side elevation of the second rolling sleeve 42 is a hyperbolic surface, and the second rolling sleeve 42 is located between the protrusions at both ends of the first rolling sleeve 41.

[0034] In this case, positioning sleeves are provided at both ends of the first rolling sleeve 41, and the positioning sleeves limit the first rolling sleeve 41 from generating axial displacement, while the second rolling sleeve 42 is limited between the protrusions at both ends of the first rolling sleeve 41 and does not generate axial displacement. Therefore, there is no need to provide positioning sleeves at both ends of the second rolling sleeve 42, which facilitates disassembly and assembly and saves costs.

[0035] Preferably, the first rolling sleeve 41 and the second rolling sleeve 42 are arranged along the chord length direction of the air volume adjustment plate 3 and are located between the two air volume adjustment plates 3 .

[0036] In order to further improve the suction force of the suction side air duct 2, Figure 5 As shown, the axial cross-section of the air duct sleeve 1 is stepped, and the ventilation area of ​​the air duct sleeve 1 increases step by step from the air suction port to the inside.

[0037] In order to fix the suction side air duct 2, a top screw 12 is provided at the connection between the air duct sleeve 1 and the suction side air duct 2. The top screw 12 fixes the air duct sleeve 1 to the end of the suction side air duct 2. By removing the top screw 12, the air volume adjustment device and the suction side air duct can be disassembled.

[0038] The working principle of this utility model:

[0039] When in use, the duct sleeve 1 is sleeved on the end of the edge suction duct 2, and the duct sleeve 1 and the edge suction duct 2 are fixed by using the top screw 12. By rotating the air volume adjustment plate 3, the opening size of the duct sleeve 1 can be adjusted, and then the suction force of the edge suction duct 2 can be adjusted; after adjusting the air volume adjustment plate 3, tighten the fasteners to fix the air volume adjustment plate 3 on the outer end face of the duct sleeve 1; after the edge suction duct 2 starts the suction operation, the material enters the duct sleeve 1 from the gap between the air volume adjustment plate 3 and the duct sleeve 1, and enters the edge suction duct 2 as the rolling element 4 rotates, avoiding the problem of belt breakage during the adsorption of longer edge materials.
