Jacquard machine with low machine body, low weight and high stability

Abstract

The invention discloses a low-machine-body, low-weight and high-stability jacquard machine which comprises bottom beams arranged in parallel front and back, a longitudinal rotating shaft supported on the bottom beams, a first longitudinal swing shaft and a second longitudinal swing shaft, a first eccentric wheel and a second eccentric wheel are installed at one end of the longitudinal rotating shaft at intervals, and a driving fixed crank and a movable crank are installed at one end of the first longitudinal swing shaft at intervals. The driving fixed crank is connected with a first eccentric wheel through a first transverse connecting rod, and the movable crank is connected with a second eccentric wheel through a second transverse connecting rod and connected with the driven crank through a third transverse connecting rod. External lifting arms and internal lifting arms are alternately fixed on the first longitudinal swing shaft and the second longitudinal swing shaft at intervals, the external lifting arms on the first longitudinal swing shaft and the second longitudinal swing shaft are respectively hinged with a group of longer transverse griffes through outer hanging rods, and the internal lifting arms on the first longitudinal swing shaft and the second longitudinal swing shaft are respectively hinged with a group of shorter transverse griffes through inner hanging rods. The aircraft is short in fuselage, light in weight, high in stability, small in transverse space and low in power consumption.

Description

【Technical field】 [0001] The invention relates to a jacquard machine with a short body, low weight and high stability, belonging to the technical field of jacquard opening machinery. 【Background technique】 [0002] Please refer to Patent No. ZL2015106829728, the name is high-speed and heavy-load jacquard opening device, the double-sided wall panels 1L and 1R of this patent are fixed on the bottom frame or bottom beam G, and the eccentric axle 3 (center rotation axis) arranged horizontally needs to be installed in the center At the bottom of the wall panels 1L and 1R on both sides, the disadvantage is that it interferes with the maintenance work. The swing shafts installed on the double wall panels at a high position need 4 swing shafts 51L, 52L, 51R, 52R (some need to be horizontally penetrated through both sides). The upper and lower double swing shaft structure of the wall panel), the connecting rods 41L, 42L, 41R, 42R are all vertical connecting rods, using 8 vertical con...

Problems solved by technology

[0002] Please refer to the patent No. ZL2015106829728, which is named high-speed heavy-duty jacquard opening device. The double-sided wall panels 1L and 1R of this patent are fixed on the bottom frame or bottom beam G, and the eccentric wheel shaft 3 (central shaft) arranged horizontally needs to be installed in the center. At the bottom of the wall panels 1L and 1R on both sides, the disadvantage is that it interferes with the maintenance work. The pendulum shafts installed on the double wall boards at a high position need 4 pieces, namely the pendulum shafts 51L, 52L, 51R, and 52R (some also need to run through both sides horizontally). The upper and lower double swing shaft structure of the wallboard), the connecting rods 41L, 42L, 41R, and 42R are all vertical connecting rods, and 8 vertical connecting rods and a group of two external tool holders 21L, 21R and a group of two internal tool holders are used. The tool holders are 22L and 22R. This model has a high body, heavy weight, poor stability, and low power consumption and energy saving.
