ASGA type flexible rapier loom
ASGA751 (mechanical dobby) and ASGA751D (electronic dobby) flexible rapier looms are new shuttleless weaving machines independently developed by Jiangsu Dahong Group Yancheng Honghua Fabric Machinery Co., Ltd. based on my country’s specific realities. machine. This machine is suitable for weaving light, medium and heavy fabrics of various natural and synthetic fibers. The design of this machine focuses on the reliability and stability of the loom. The whole machine has a low center of gravity, stable operation, easy operation, and easy maintenance. Can weave single width, double width or multiple width fabrics. Ideal for wide fabrics.
Suitable for weaving varieties of yarns. It can weave various natural fibers (such as cotton, wool, silk, linen) and various regenerated fibers and synthetic fibers.
Fabrics It can weave light, thin and heavy fabrics in the range of 20-800g/m2, and is suitable for various fabrics such as woolen woolen cloth, linen, silk, cotton and chemical fibers.
The transmission mechanism is driven by a 5.5kW main motor through an electromagnetic clutch and braking device to drive the reed base and sword belt. The electromagnetic clutch, braking device and electronic control system cooperate to accurately control the positioning, parking, starting and other functions of the loom.
The warp let-off device adopts a stand-alone servo motor to control the warp let-off mechanism. The control panel can be used to input and adjust the total warp tension so that the warp yarn maintains constant tension from the full shaft to the empty shaft.
Electronic color selection device Stand-alone mechanism, 2 to 6 colors can be selected at will.
Weft insertion mechanism The weft insertion mechanism is a double sword supplying weft from one side. The sword belt driven by the conjugate cam and the clamping weft clamper transfer the weft yarn in the center to complete the weft insertion.
The optimally designed and carefully arranged conjugate cam controls the entire weft insertion process, which can make the rapier head’s leisure pattern more reasonable and ensure stable weft tension, reliable handover and smooth operation when the loom is running at high speed.
Beating-up mechanism The beating-up mechanism is driven by a conjugate cam with a short reed base and a separate reed base. It uses inertial beat-up to reduce the impact and energy consumption of leisure.
The beat-up conjugate cam has the same high precision as the weft insertion conjugate cam, driving a strong short reed seat to ensure the beat-up force when weaving high-density fabrics and heavy fabrics.
Automatic weft selection device is equipped with automatic weft finding device and slow-moving forward and backward devices. If the weft yarn is broken, the automatic weft finding device will automatically rotate the loom to the cloth fell when the weft is broken. During this process, the microprocessor will control the synchronous operation of all mechanical aspects, which can effectively prevent driving marks caused by stopping the loom, thereby ensuring the quality of the fabric.
The coiling device adopts variable frequency motor for synchronous coiling. The weft density setting can be completed by inputting only through the multi-function operation panel, and the fabric can be dropped while the loom is running.
The weft density adjuster is linked with the warp take-up mechanism. You can easily adjust the weft density by turning the handwheel. The weft density range is 25-160 threads/10 cm.
The edge-twisting device adopts a cam-driven independent-station leno edge-twisting mechanism.
The opening device adopts a positive bottom-mounted electronic dobby opening. The heald frames always remain gap-free under any load or speed. It can be equipped with up to 20 heald frames. According to the designed fabric structure, the lifting and lowering of the heald frame is controlled by pre-programmed pattern plates, pattern papers or programs.
Auto-stop device adopts electronic warp-break auto-stop device and electronic weft sensor, which can accurately and reliably detect warp or weft breakage during weaving.
The dust suction mechanism adopts a rotating vortex air pump, and the continuous air flow removes the dirt attached to the sword belt, avoiding affecting the fabric quality and startup efficiency. It also has a blower and heat dissipation function.
Lubrication device adopts active spray oil circulation system for lubrication. The main transmission gear train adopts oil bath lubrication, the balance shaft bearing adopts regular forced lubrication, and the parts without oil bath adopt sealed bearings.
Control and detection adopts a microcomputer control system, with functions such as automatic weft search, fault detection, automatic weft selection, automatic stop for warp break, automatic stop for weft break, and LCD display.
All operations of this loom are operated by buttons installed on the upper beam. Starting, parking, forward and reverse idle, forward and reverse weft search, parking indicator light, and emergency stop have their own button controls.
The electric control box is equipped with an indicator light. The red light indicates stop for weft break and the green light indicates stop for warp break. The electric control box is equipped with a main motor control switch, a manual and automatic transfer switch, and a red emergency button to cut off the power supply in an emergency. wait.
