Saw dust rod forming machine and repairing method thereof

Abstract

The invention provides a wood chip bar shaping machine and a repairing method thereof. The wood chip bar shaping machine has a structure capable of easily repairing even if a shaping machine used by the wood chip bar shaping machine is abraded. The wood chip bar shaping machine presses wood chips into a compression cylinder with reduced inside diameter from an inlet towards an outlet, and the wood chips pass through the shaping machine provided with a groove shaping component on the inner surface and having reduced inside diameter, so as to form a high-temperature and high-pressure state, and shape as the wood chip bar shaping machine for a bar-shaped wood chip bar provided with grooves on the surface, wherein because the groove shaping component is arranged to be disassembled relatively to the shaping machine, the groove shaping component can be disassembled from a shaping machine body when being repaired and is applied with overlaying welding, grinding and the like respectively.

Description

technical field [0001] The invention relates to a sawdust rod forming machine which compresses sawdust to form a sawdust rod and a repair method thereof. Background technique [0002] As a sawdust stick forming machine which compresses sawdust and forms a sawdust stick, the forming machine proposed by the inventor is known. [0003] like image 3 As shown, the conventional molding machine 200 is configured to apply pressure to wood chips such as sawdust by using a helical screw compressor 300 , press them into a cylindrical former 100 , and compress them. Since the groove forming member 110 protrudes from the inner surface of the shaper 100, grooves are formed on the surface of the formed wood chip stick. [0004] like Figure 4 As shown, a groove forming member 110 is protrudingly provided on the inner surface of a conventional shaper 100, thereby forming a sawdust stick having grooves. [0005] The lignin contained in the wood chips acts as a binder by the frictional he...

AI Technical Summary

Problems solved by technology

However, although the worn part is the corner part of the groove forming member, the former must be replaced as a whole, so there is a problem that it costs a lot.

[0008] In particular, when the molding speed is increased in order to reduce the unit price of wood chip sticks, there is a problem that the above-mentioned formers are worn out rapidly.

[0009] In addition, if only the corner part of the groove forming part of the former is repaired by overlay welding, etc., although the cost can be saved, however, since the groove forming part The inner side protrudes, so there is a problem that repair work is difficult
