Tractor

Abstract

The invention discloses a tractor. The tractor comprises a frame and a conveying device arranged on the frame; the frame is also provided with a traction guide rail; the traction guide rail is positioned near the conveying device; the traction guide rail is provided with a traction device which reciprocates in the guiding direction of the traction guide rail; the conveying device is provided witha cutting device for cutting sectional profiles; the traction device is positioned at the lower station of the cutting device; the cutting device comprises a sawtooth block and a driving motor for controlling the running state of the sawtooth block; the frame is also provided with a sound insulation cover arranged in the direction of the traction guide rail; a cavity is formed in the sound insulation cover; one end side of the sound insulation cover is provided with an opening communicating with the cavity; the conveying device and the cutting device are both positioned in the cavity; and a noise reduction system is arranged in the cavity. According to the tractor, the noise generated by the sawtooth block is reduced in an active noise reduction mode, the noise reduction effect is obvious,the mechanical noise reduction by traditionally using a cover body to cover the sound source to isolate air circulation is replaced, the automation degree is high, the traditional labor force is replaced, and good practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to a tractor. Background technique [0002] In the industry, the processing and cutting of aluminum profiles basically adopts a fully automated traction mechanism. During the continuous extrusion production process of aluminum profiles, the tractor is used to move and separate them. Existing typical or common existing technologies include: [0003] As CN209255506U discloses a kind of aluminum tractor, it utilizes ratchet bar and bite plate to realize that the aluminum is fixed and loosened, and then the movement of the traction motor and the frame drives the aluminum to shift rapidly. Another classic, such as CN206605108U, discloses a double-saw double tractor for aluminum, which includes a first trolley track parallel to the conveying roller table, a second trolley track, and a first trolley track walking on the first trolley track. The trolley and the second ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, after a massive search by the applicant, it was found that the sawing during the use of the tractor produces a lot of noise, but so far there is no prior art or patent application document to solve this problem

Of course, those skilled in the art can easily think of using a cover to seal and isolate noise, but this approach has little effect. Therefore, it is necessary to develop or improve a tractor to solve the above problems
