Example Embodiment

[0022] In the following, the present invention will be further clarified with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, those skilled in the art have Modifications in equivalent forms fall within the scope defined by the appended claims of this application.

[0023] Such as figure 1 , figure 2 with image 3 The shear pin safety mechanism of a pellet machine shown includes a gear box 1. A shear pin cover 2 is fixedly connected to one side of the gear box by bolts. The end of the pellet machine main shaft 10 penetrates the shear pin cover 2, and The end surface of the cutting pin cover 2 is covered with a shear pin flange 3 fixedly connected to the end of the main shaft of the pellet machine. One end of the shear pin flange 3 is inserted into the cover of the cutting pin and connected to ...

Abstract

The invention discloses a granulator shear-pin safety mechanism. The granulator shear-pin safety mechanism comprises a granulator support or a gearbox, the granulator support or the gearbox is provided with a shear-pin guard, a main shaft of a granulator penetrates through the shear-pin guard, the end face of the shear-pin guard is covered with a shear-pin flange fixedly connected with the main shaft of the granulator, and a plurality of shear pins are arranged between the shear-pin flange and the shear-pin guard. The shear-pin guard is provided with a travel switch monitoring rotation of the shear-pin flange, the travel switch is connected with a power control device of the granulator, the granulator stops working when the shear-pin flange shifts, a shield is hinged to the shear-pin guard, and the tail end of the main shaft is covered with the shield. The tail end of the main shaft of the granulator is closed, and therefore when the shear pins are shorn off, the granulator can stop working, and due to dual protection of a mechanical structure and electronic control, the granulator can meet new safety standards issued in North America and Europe.

Description

technical field [0001] The invention relates to a granulator, in particular to a shear pin safety mechanism of a granulator, which belongs to the technical field of food and feed processing equipment. Background technique [0002] Pelletizers usually have a shear pin to protect components such as ring dies, rollers, spindles, gear drives or belt drives from being damaged by overload during the pelletizing process. The reason for overloading is that impurities enter the nip between the die and the roller, and it may also be caused by the fact that the feed material is difficult to pelletize. According to the size of the pellet mill, one, two or three shear pins can usually be selected, and the neck size of the shear pins can be strengthened to withstand 150% to 200% overload. Prior art pellet mill shear pin mechanisms include: [0003] 1. Fixed shear pin housing mounted on pellet mill frame or gearbox. [0004] 2. Shear pin flange fixed to the end of the main shaft of the ...
