Upper cover seal structure of kneader

Abstract

The invention relates to an upper cover seal structure of a kneader. The upper cover seal structure of the kneader comprises a cylinder body and an upper cover of the kneader; the cylinder body is open upward; the height of the open edge at the front surface of the cylinder body is lower than those of the open edges at the left side wall and right side wall of the cylinder body; the upper cover of the cylinder body is of a folded-edge-type structure, and is movably connected with the rear side wall of the cylinder body; the upper cover turns over upward so as to open the opening, and turns over downward so as to form sealed and enclosed connection with the edge of the opening, and the opening is sealed integrally; the heights of the opening edges of the left side wall and right side wall of the cylinder body are equal to that of the rear side wall of the cylinder body; and the upper cover of the cylinder body is connected with the rear side wall of the cylinder body through a hinge mechanism. Compared with the prior art, the upper cover seal structure has the following advantages: when the kneader discharges materials and turns over and part materials in the cylinder body do not completely turn cover in place, materials can be discharged through a notch at the front surface of the cylinder body; and the subsequent materials are adsorbed and positioned by the two side walls of the cylinder body and are difficult to overflow. The upper cover seal structure of the kneader provided by the invention is simple in structure, and can be used for effectively solving the problem that when the kneader discharges materials, BMC (bump molding compounds) material bumps are easy to overflow.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a sealing structure for an upper cover of a BMC kneader. Background technique [0002] BMC is a bulk unsaturated polyester glass fiber reinforced molding compound, also known as thermosetting bulk molding compound. Its main raw materials are chopped glass fiber (GF), unsaturated polyester resin (UP), filler (MD), and various A prepreg in the form of a lump made by thoroughly mixing two kinds of additives. Belonging to one of the thermosetting molding materials, BMC materials have excellent electrical properties, mechanical properties, heat resistance, and chemical corrosion resistance, and are suitable for various molding methods such as compression molding, injection molding, and transfer molding. BMC material formula It can be adjusted flexibly and can meet the performance requirements of various products. It is mainly used in the fields of electrical appliances, mo...
