Double face needle loom

Abstract

The invention discloses a double-face needle loom. It includes a frame, on which a main transmission system is arranged, and the main transmission system includes a drive unit, a first main shaft and a second main shaft; wherein, the first main shaft or the second main shaft is provided with There is a sprocket, and the drive unit is connected to the sprocket through a chain; one end of the first main shaft and the second main shaft are connected through a coupling; the other ends of the first main shaft and the second main shaft extend out of the machine respectively. Outside the frame, two eccentric wheels are fixed at the protruding end of each main shaft, and the eccentric directions of the two eccentric wheels are opposite. In the above-mentioned structure of the present invention, the structure of the main transmission of the needle loom is simple, and the chain transmission adopted is convenient for maintenance; the compacting device is a swing type, which does not affect the main transmission, and the vibration of the machine body is small, so that high-speed acupuncture can be realized. It is of great significance to improve the bulk density and tensile strength of the product.

Description

technical field [0001] The invention relates to a double-face needle loom, which can be applied to the production of aluminum silicate fiber needle-punched blankets, rock mineral wool, centrifugal glass wool and the like. Background technique [0002] Acupuncture machine is the key equipment in the production line of aluminum silicate fiber needle-punched blanket, rock mineral wool and centrifugal glass wool. Its main function is to increase the density and tensile strength of needle-punched blanket. The prototype of the double-face needle loom on the market is still an acupuncture machine introduced from France in the 1980s. The main drive system of this needle loom contains 4 main shafts and is equipped with a stepping system. , the structure is very complex (such as figure 1 shown), and the main drive is a V-belt drive, and the sub-drives on both sides are toothed belt drives. When replacing the V-belt and the toothed belt, the main shaft and coupling need to be removed....

Problems solved by technology

The prototype of the double-face needle loom on the market is still an acupuncture machine introduced from France in the 1980s. The main drive system of this needle loom contains 4 main shafts and is equipped with a stepping system. , the structure is very complex (such as figure 1 shown), and the main drive is a V-belt drive, and the sub-drives on both sides are toothed belt drives. When replacing the V-belt and the toothed belt, the main shaft and coupling need to be removed. Maintenance is more troublesome, and more importantly, the In actual use, it was found that the toothed belt skipped teeth after being used for a period of time, which caused the eccentric booms at both ends of the acupuncture machine to be out of sync, posing a production safety hazard
