Safe-to-use sliding table saw and safety use method

Abstract

The invention discloses a safe-to-use sliding table saw and a safety use method, and belongs to the field of woodworking machinery. The safe-to-use sliding table saw comprises a sliding table saw body, a lifting assembly and a saw blade shield, wherein the sliding table saw body comprises a processing table for placing wood, a rotary saw blade fixedly connected with the processing table and a sawdust collecting assembly fixedly arranged at one end of the rotary saw blade; the lifting assembly performs up-and-down linear motion on one side of the rotary saw blade; the saw blade shield comprisesa shield body, an elastic assembly and a rolling assembly; the shield body is fixedly connected with the lifting assembly through the elastic assembly; the shield body abuts against timber through the rolling assembly; and a humidifying assembly is arranged in the shield body. According to the safe-to-use sliding table saw and the safety use method, an existing sawdust recycling function is reserved, the resistance generated when the shield body abuts against the timber is reduced through the rolling assembly, the abutting between the shield body and the timber is achieved, the safety of workers in misoperation is improved, and the probability of fire is reduced by humidifying the timber and the rotary saw blade through the humidifying assembly.

Description

technical field [0001] The invention belongs to the field of woodworking machinery, in particular to a safe use sliding table saw and a safe use method. Background technique [0002] The work of the sliding table saw is to push the wood against the stopper to the direction of the saw blade, and cut the wood through the high-speed rotation of the saw blade. [0003] Existing sliding table saws have severe heat generation when the saw blade is working for a long time, which will cause burns to the wood and affect the subsequent processing of the wood, especially when the saw blade is worn out, the heat will be more serious, and the excessive temperature will easily cause friction with wood and wood chips. In order to cause a fire, the existing technical solution is only to set a receiving port in the protective cover to absorb the sawdust, and does not fundamentally solve the problem of saw blade heating; in the prior art, the resistance caused by the direct contact between th...

Problems solved by technology

[0003] Existing sliding table saws have severe heat generation when the saw blade is working for a long time, which will cause burns to the wood and affect the subsequent processing of the wood, especially when the saw blade is worn out, the heat will be more serious, and the excessive temperature will easily cause friction with wood and wood chips. In order to cause a fire, the existing technical solution is only to set a receiving port in the protective cover to absorb the sawdust, and does not fundamentally solve the problem of saw blade heating; in the prior art, the resistance caused by the direct contact between the protective cover and the wood The wood feeding process increases the physical labor of the staff. The technical scheme adopted is to reserve a large gap between the protective cover and the wood. Although this technical scheme reduces the physical labor of the staff, the protection In the cover, the wind force from the receiving port has been used to absorb the sawdust, and the high-speed rotation of the saw blade forms a negative pressure in the protective cover, which easily sucks the sundries on the wooden board into the protective cover and collides with the saw blade, which accelerates the wear of the saw blade speed

[0004] In addition, in the operating instructions of the sliding table saw, it is stipulated that the staff with long hair should tie up their long hair because the staff with long hair will easily get their hair stuck on the saw blade and cause damage to the staff. During the work, there will be staff with long hair who have just started working because they are not familiar with the work process and make misoperations, causing the long hair to be attracted by the negative pressure of the protective cover and enter the protective cover from the gap between the protective cover and the wood and get stuck on the saw blade. above, causing danger to the life of the staff who misoperated
