Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0012] A die cover connection structure for a granulator, in which two holes are arranged on the outer edge of the die cover 2.1, and two screw holes 2.3 are provided on the die base corresponding to the positions of the holes, through which two A bolt 2.3 connects the die seat and the die cover 2.1.
[0013] In this example, the two holes of the die cover 2.1 are arranged on the straight line where the die cover 21 has the same diameter. The outer edge of the die cover 2.1 is provided with two radial projections 2.2, and the two holes are respectively provided on the two projections 2.2.

The invention relates to a die cover connection structure for a granulator. The outer edge of the die cover has two holes, the position on a die seat corresponding to the holes has two threaded holes which are connected with the die seat and the die cover through two bolts. Compared with the prior art, the die cover connection structure for the granulator solves the problems in the prior art based on the simple structure.
Description
technical field [0001] The invention belongs to the technical field of granulation machinery, in particular to a die cover structure for a granulation granulator. Background technique [0002] The die cover is also called the material box, and it is mostly used in feed and biological pellet granulation machines. The die cover is detachably connected with the film holder. Due to the extremely high temperature (close to the ignition point of wood) generated during the operation of the granulator, the thermal expansion and contraction of the die cover and the die seat generate huge tension. This change makes the gap between the die cover and the die seat The fastening screws are often broken. In the prior art, the number of commonly used fastening screws is 6, which are evenly distributed along the outer edge of the die cover. The idea of some technicians is to overcome the tension caused by thermal expansion and contraction by increasing the number of fastenings, so as to a...
