An air cooling device for cooling the circular saw blade

Abstract

The invention relates to an air-cooling device for cooling circular saw blades, which comprises a compressed air delivery pipe, a saw blade shaft, a rotary joint and several pieces of circular saw blades, and the rotary joint includes a stationary shaft of the rotary joint and a sealing system of the rotary joint And the swivel joint swivel sleeve, wherein: the compressed air delivery pipe is connected to the stationary shaft of the swivel joint, and the swivel joint swivel sleeve is connected to the outer end of the saw blade shaft through the saw blade lock nut, so as to realize the connection between the swivel joint and the saw blade shaft. Through the air-cooling device of the present invention, the compressed refrigerated gas is sprayed out through the compressed air injection groove and then goes along the base of the circular saw blade until the hard alloy saw blade is finally absorbed by the dust collection system together with the sawdust. Part of the compressed and frozen air is sprayed into the saw kerf between the heavy bamboo (wood) glulam and the circular saw blade, thereby blowing away the dust sandwiched between and reducing the friction between the substrate of the circular saw blade and the heavy bamboo (wood) glulam , so as to achieve the purpose of cooling the circular saw blade, and also ensure the drying effect in the seam.

Description

technical field [0001] The invention relates to the field of cold-pressed heavy bamboo laminated lumber manufacturing, in particular to an air cooling device for cooling circular saw blades. Background technique [0002] At present, the last process in the production of cold-pressed heavy bamboo (wood) glulam manufacturers is slicing, which is to cut the dried heavy bamboo (wood) glulam into boards after forming and curing, in order to improve the quality of heavy bamboo (wood) ) The utilization rate of glulam requires the thinner the circular saw blade used for cutting, the better, but the thickness of the circular saw blade is limited due to the material and process, and the circular saw blade is suitable for sawing hard and thick heavy bamboo. (Wood) Glulam will generate high temperature due to the strong friction of the saw blade, and at the same time, the powder remaining in the saw kerf will rub against the saw blade substrate to generate high temperature. The above tw...

[0002] At present, the last process in the production of cold-pressed heavy bamboo (wood) glulam manufacturers is slicing, which is to cut the dried heavy bamboo (wood) glulam into boards after forming and curing, in order to improve the quality of heavy bamboo (wood) ) The utilization rate of glulam requires the thinner the circular saw blade used for cutting, the better, but the thickness of the circular saw blade is limited due to the material and process, and the circular saw blade is suitable for sawing hard and thick heavy bamboo. (Wood) Glulam will generate high temperature due to the strong friction of the saw blade, and at the same time, the powder remaining in the saw kerf will rub against the saw blade substrate to generate high temperature. The above two results will occur in an environment where saw blades are densely installed. The saw blade base will be deformed quickly and the bill will be charged, and the thinner the saw blade will be, the more serious the situation will be
