[0022]

Embodiment 1

[0023] A positioning device, such as Figure 1 、 Figure 2, including a positioning component, which includes a telescopic power mechanism 11, a moving seat 17, a limiting frame 12, a hook plate 13 and a guiding body 16. Both the telescopic power mechanism 11 and the hook plate 13 are installed on the moving seat 17. When the telescopic power mechanism 11 operates, the moving seat 17 drives the hook plate 13 to move synchronously. The hook plate 13 is preferably a right-angled plate. One right-angled side of the hook plate 13 is rotatably connected to the moving seat 17. After the hook plate 13 contacts the guiding body 16, the hook plate 13 rotates to achieve the positioning effect of the material. The limiting frame 12 is used to limit the maximum rotation angle of the hook plate 13.

[0024] In this embodiment, the positioning surface of the hook plate 13 is a plane. In other embodiments, the positioning plane of the hook plate 13, that is, the contact surface with the material, can be set to other shapes for cooperating with the material positioning.

[0025] Such as Figure 2 , the guiding body 16 is arranged below the hook plate 13, and a guiding inclined surface 161 is arranged on the guiding body 16. Further, a roller 14 is installed on the hook plate 13, and the roller 14 is used to contact the guiding body 16 to reduce the friction force.

[0026] Such as Figure 2 , the guiding surface includes a guiding inclined surface 161 and a guiding plane 162. When the roller 14 contacts the guiding inclined surface 161, the hook plate 13 changes its angle. When it contacts the guiding plane 162, it maintains the angle. In other embodiments, different types of guiding surfaces can be set according to different requirements of the angle change of the hook plate.

[0027] The telescopic power mechanism 11 generally uses a cylinder, and an electric cylinder, a hydraulic cylinder, etc. can also be used. Such as Figure 2 , for the convenience of installation and adjustment, a length adjustment structure 15 is arranged on the connecting part between the cylinder and the moving seat 17. The length adjustment structure 15 can be realized by a bolt structure or a telescopic rod. In this embodiment, a spherical bearing is installed on the moving seat 17, and the overall length of the connecting part is adjusted by adjusting the length of the piston rod end of the cylinder inserted into the spherical bearing.

[0028] Generally, a single positioning component can achieve unilateral material positioning. Preferably, in this embodiment, at least two groups of positioning components are provided, namely positioning component 1 and positioning component 2, and the two groups of positioning components are symmetrically arranged left and right on the frame 3.

[0029] In order to make the material positioning process stable, the positioning component further includes a linear guide rail 18. The moving seat 17 is installed on the linear guide rail 18, and the linear guide rail 18 is installed on the frame 3.

[0030] The positioning component is installed on the frame 3, wherein the telescopic power mechanism 11, the linear guide rail 18 and the guiding body 16 are installed on the frame 3, and the frame 3 is installed on the conveyor to achieve convenient installation.

[0031] Furthermore, as shown in Figure 3 and Figure 4 , a groove 131 is provided on the hook plate 13, and the guiding body 16 can extend into the groove 131, so that the hook plate 13 remains stable during rotation, reducing the front-back swing caused by the installation gap.

[0032] When the air cylinder pushes the moving seat 17 to reciprocate along the linear guide rail, due to the self-weight of the hook plate and its connection to the moving seat 17, the hook plate 13 is always perpendicular to the guiding surface of the guiding body 16. Therefore, the hook plate 13 can present different swinging angles according to different positions of the roller 14 on the guiding body 16. When the roller is at the straight section of the guiding body, the hook plate remains vertically upward. When the roller 14 is at the inclined section of the guiding body 16, the hook plate swings downward. When the air cylinder retracts, the hook plate 13 will remain vertical under the restriction of the limit frame 12 and will not incline inward.

[0033] Features of this product:

[0034] When the two air cylinders act separately, they can control the stroke of the single-sided hook plate, so that the conveyed material is positioned on one side close to the edge. When they act simultaneously, they can control the hook plates to move inward simultaneously, so that the conveyed material is centered.

[0035] The forward and backward movement of the hook plate is driven by the air cylinder, and the downward movement is driven by its own gravity, with a simple structure.

[0036] A guiding body is provided at the bottom of the device, and rollers are provided on the hook plate, which can reduce the force on the air cylinder through the rolling between the rollers and the guiding body.

[0037] A limit frame is provided to limit the inward inclination of the hook plate.

[0038] The running track of the hook plate can be controlled by changing the shape and size of the guiding body 16, which is compatible with different specifications of conveyed materials.

[0039] A conveyor includes the above positioning device, and the positioning device can be installed on the conveying plane of a material conveyor, such as a chain conveyor, a belt conveyor, etc.

[0040] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments. Without departing from the said principle, the embodiments of the present invention can have any deformation and modification.
