[0020] The following description is only used to disclose the present utility model so that those skilled in the art can implement the present utility model. The embodiments in the following description are only for illustration, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be applied to other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other schemes that do not deviate from the spirit and scope of the present utility model.

[0021]

Embodiment 1

[0022] A positioning device, such as Figure 1 , includes a mounting bracket 1 and a positioning component 2. The mounting bracket 1 is used to conveniently mount the positioning device on the conveyor. The form of the mounting bracket 1 is set according to the specific structure of the conveyor. In this embodiment, a channel steel is used as the mounting bracket.

[0023] The positioning component 2 includes a driving assembly 23, a limit block 21, a pull rod 22, and a transmission rod 24.

[0024] The driving assembly 23 generally uses a cylinder, and an electric cylinder or a hydraulic cylinder can also be adopted.

[0025] The limiting block 21 is provided with a slideway 212. To ensure stable movement, the slideway 212 is internally arranged. The limiting block 21 is a square block, and the slideway 212 is arranged inside the limiting block 21 and penetrates through the limiting block 21.

[0026] Specifically, the air cylinder is installed on the mounting bracket through a fixed pin shaft. A transmission rod 24 is installed at the end of the air cylinder. The pull rod and the transmission rod 24 are connected by a pin shaft and can rotate relative to each other. The limiting block 21 is fixed on the mounting bracket by bolts. The slideway 212 is arranged inside the limiting block 21. The pull rod 22 and the transmission rod 24 can slide freely in the slideway 212. A guiding surface, namely a curved surface 211, is arranged on one side of the limiting block 21. The pull rod can move along the guiding surface under the action of its own gravity.

[0027] The driving assembly 23 is used to drive the transmission rod 24 to move in the slideway 212. The pull rod 22 has a connecting portion 222 and a positioning portion 221. The angle between the connecting portion 222 and the positioning portion 221 is less than 180°, preferably 90°. The transmission rod 24 is connected to the driving assembly 23 and the connecting portion 222. The connecting portion 222 and the transmission rod 24 are rotatably connected. When the connecting portion 222 enters the slideway 212, the pull rod 22 is squeezed by the limiting block 21 and rotates, and the positioning portion 221 positions the material.

[0028] A single set of positioning assembly 2 can achieve unilateral positioning. In this embodiment, at least two sets of positioning assemblies 2 are provided and symmetrically arranged. The driving assemblies 23 on both sides can be controlled separately.

[0029] Optionally, both the driving assembly 23 and the limiting block 21 are installed on the mounting bracket 1. Multiple mounting positions can be set on the mounting bracket 1 to adapt to different conveyors, facilitating the installation of the positioning assembly 2 at different positions.

[0030] Preferably, in order to prevent the pull rod 22 from jamming when rotating and improve the smoothness of rotation, a curved surface 211 is provided at the opening of the slideway 212 on the limiting block 21. Further, the curved surface 211 is provided both above and below the opening of the slideway 212, so that the limiting block 21 does not need to be distinguished between front and back during installation. A mating curved surface 223 is provided on the connecting portion 222 for mating with the curved surface 211.

[0031] When the air cylinder does not extend, the connecting portion 222 of the pull rod is inside the slideway 212, and at this time the pull rod is in a vertical state. When the air cylinder extends, it pushes the transmission rod 24 and the pull rod to move in the slideway 212. When the pull rod exits the slideway 212, it moves downward under the action of its own gravity to complete the swing of the pull rod.

[0032] Features of this product:

[0033] The swinging and tensioning and positioning of the drawbar can be completed in one action, and the structure is simple.

[0034] The two cylinders can be controlled separately to be compatible with different material sizes and positioning positions.

[0035] The transmission rod 24 and the drawbar are connected by a pin shaft, and there is no complex transmission mechanism, avoiding the "dead point" problem in the traditional connecting rod mechanism.

[0036] The pneumatic positioning device in this solution is mainly used to position the conveyed material at a specified position. When it is installed below the conveying line, the conveyed material can be centered or positioned on the side.

[0037] 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.

[0038] 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 described in the embodiments. Without departing from the said principle, the embodiments of the present invention can have any deformation and modification.
