Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation board cutting equipment, in particular to a cutting mechanism and a thermal insulation board cutting machine. Background Art

[0002] Insulation boards are widely used in the building exterior wall insulation market. In order to cut insulation boards to meet different installation requirements, insulation board cutting machines have appeared on the market.

[0003] When using the existing cutting machine, the tension of the saw blade is adjusted manually. However, during manual adjustment, the cutting accuracy cannot be unified due to the different tightness of the manual tension. In addition, the friction heat generated by the saw blade after a long period of cutting will cause the temperature of the saw blade to rise, resulting in thermal expansion and deformation, which in turn affects the tension of the saw blade. After a period of use, the saw blade is prone to loosening and falling off, affecting the normal production. For this reason, we have designed an insulation board cutting machine (patent number: CN 111619018 A, name: an insulation board cutting machine) to solve the above problems.

[0004] However, the slideway of the cutting mechanism in the above-mentioned cutting machine adopts the precision slideway purchased for finished machine tools, which is lubricated with lubricating oil. When the cutting saw is working, a lot of dust will be generated. After the dust contacts the lubricating oil, it will harden and agglomerate. It must be disassembled regularly and cleaned with diesel, which is very inconvenient. Utility Model Content

The driven saw disc is slidably connected to the fixed plate through a sliding mechanism, which is used to adjust the distance between the driven saw disc and the active saw disc, so as to facilitate the assembly and disassembly of the saw blade.

It can also avoid the problem that the sliding mechanism is blocked and cannot slide normally after the dust hardens, which makes it inconvenient to install and remove the saw blade, and can improve the efficiency of installation and removal. Moreover, it does not need to be frequently disassembled and cleaned with diesel, which can reduce maintenance costs.

[0020] The beneficial effects of the utility model are:

[0021] 1) It can solve the problem that a large amount of dust generated by the existing cutting saw during operation hardens and agglomerates after contacting the lubricating oil in the sliding mechanism.

[0022] 2) It can also avoid the problem that the sliding mechanism is blocked from sliding due to the hardening of dust, which makes it impossible to slide normally and makes it inconvenient to install and disassemble the saw blade, thereby improving the efficiency of installation and disassembly.
