Double-sided needling type needle-punching machine

Abstract

The invention discloses a double-sided needling type needle-punching machine. The double-sided needling type needle-punching machine comprises a rack which is provided with a main transmission system, and the main transmission system comprises a driving unit, a first spindle and a second spindle; a chain wheel is arranged on the first spindle or the second spindle, and the driving unit is in transmission connection with the chain wheel through a chain; one end of the first spindle is connected with one end of the second spindle through a coupling; the other end of the first spindle and the other end of the second spindle extend out of the rack, two eccentric wheels are fixedly arranged on the extending end of each spindle, and the eccentric directions of every two eccentric wheels are opposite. According to the double-sided needling type needle-punching machine, the needle-punching machine main transmission structure is simple, and due to the fact that chain transmission is adopted, maintenance is convenient; a compacting device adopts a swing type, main transmission is not affected, machine body vibration is small, high-speed needle punching can be achieved, and an important significance in improving the volume weight and the tensile strength of products is achieved.

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
