Description

Technical Field

[0001] The utility model relates to the field of textile machinery, in particular to a beating-up system and a water-jet and air-jet loom. Background Art

[0002] At present, the water jet looms on the market are driven by a main motor or an electric spindle to drive the driving shaft to rotate and drive the various shaft systems in the water jet loom to rotate. For example, the gear box of the water jet loom is provided with a connecting rod and a crankshaft that transmit and connect the weft beating shaft and the driving shaft. The weft beating shaft is driven to swing by the connecting rod and the crankshaft to realize the weft beating operation. The swing speed (that is, the weft beating force) and the swing angle (that is, the weft beating stroke) of the weft beating shaft are fixed. Different fabric types require different weft beating forces and weft beating strokes. Therefore, the application range of water jet looms is relatively narrow. Although the weft beating force and the weft beating stroke can be changed by changing the eccentric distance between the connecting rod and the crankshaft, this requires disassembling the gear box to replace the connecting rod and the crankshaft, which is troublesome, time-consuming and labor-intensive, and will affect the close cooperation relationship of other transmission mechanisms in the gear box, which is easy to cause transmission failure. At the same time, it is too troublesome to disassemble the gear box and replace the connecting rod and crankshaft every time a fabric type is changed.

[0003] The gear box of the water jet loom is also equipped with a gear transmission assembly that connects the opening shaft, ear wire shaft and drive shaft. A main motor or electric spindle drives the drive shaft to rotate to drive the weft shaft, opening shaft and ear wire shaft. The main motor or electric spindle has a large driving load and a low speed. The maximum speed of the loom is only about 1000 rpm, and it is difficult to improve the overall weaving efficiency. Summary of the invention

[0004] The main purpose of the utility model is to provide a beating-up system and a water jet and air jet loom, aiming to solve the problem that the beating-up force and the beating-up stroke of the beating-up system of the existing water jet and air jet loom are fixed and cannot be adjusted.

[0005] In order to solve the above problems, the utility model proposes a beating system, including a gear box and a beating shaft arranged on the gear box, the gear box is provided with a motor 1, and the motor 1 is transmission-connected with the beating shaft.

[0006] In addition, the utility model also proposes a water jet air jet loom, including the aforementioned weft beating system, and the gear box is also provided with an opening shaft and an ear wire shaft.

[0007] In one embodiment, a second motor is provided on the gear box, and the second motor is transmission-connected to the open shaft.

[0008] In one embodiment, the gear box is provided with a motor three, and the motor three is drivingly connected to the ear wire shaft.

[0009] Beneficial effects: The technical solution of the utility model directly drives the beating-up shaft to rotate by arranging a motor on the gear box, removing the connecting rod and the crankshaft, and not using a driving shaft to drive the beating-up shaft. The beating-up force and beating-up stroke of the beating-up shaft are adjusted by controlling the rotation of the motor, thereby meeting the requirements of different beating-up forces and beating-up strokes of different fabric varieties, realizing stepless variable beating-up force and beating-up stroke of the beating-up system, greatly increasing the application scope of the water jet loom, and the speed control of the motor is convenient, accurate and rapid, and can accurately adjust the beating-up force and beating-up stroke of the beating-up shaft, with high adjustment accuracy, and high automation and intelligence.

[0010] The technical solution of the utility model is to arrange motor 2 and motor 3 on the gear box to respectively drive the opening shaft and the ear wire shaft to rotate, and do not use a gear transmission component to drive the opening shaft and the ear wire shaft to rotate. In this way, the rotation speed of the opening shaft and the ear wire shaft can be adjusted independently, so as to achieve high rotation speed and significantly improve the efficiency of the loom. At the same time, the driving load of the main motor or the electric spindle is also greatly reduced. By controlling the transmission ratio of motor 1, motor 2 and motor 3, the coordinated rotation of the weft shaft, the opening shaft and the ear wire shaft is achieved. In this way, the rotation speed of the water jet loom can reach 1500-2000 revolutions, which greatly improves the production efficiency of the loom, reduces the use of wearing parts such as gears, bearings, connecting rods and crankshafts, and facilitates maintenance.

[0021] The utility model proposes a weft beating system, which directly drives the beating shaft 2 to rotate by arranging a motor 6 on a gear box 1, removes a connecting rod and a crankshaft, and does not use a driving shaft 5 to drive the beating shaft 2. The beating force and the beating stroke of the beating shaft 2 are adjusted by controlling the rotation of the motor 6, so as to meet the requirements of different beating forces and beating strokes of different fabric types, realize the stepless change of the beating force and the beating stroke of the beating system, greatly increase the application scope of the water jet and air jet loom, and the speed control of the motor 6 is convenient, accurate and rapid, and can accurately adjust the beating force and the beating stroke of the beating shaft 2, with high adjustment accuracy and high automation and intelligence.

[0022] Specifically, in an embodiment of the utility model, as Figure 1-Figure 3 As shown, the beating system includes a gear box 1 and a beating shaft 2 arranged on the gear box 1. The gear box 1 has a pair of beating shafts 2 that are symmetrically and spaced apart at both ends of the beating shaft 2. The beating shaft 2 is rotationally connected to the gear box 1.

[0023] In this embodiment, if Figure 1-Figure 3 As shown, the gear box 1 is provided with a motor 6, and the motor 6 is transmission-connected with the beating-up shaft 2. The beating-up shaft 2 is directly driven to rotate by the motor 6, and the current conventional transmission form of driving the beating-up shaft 2 to rotate by the drive shaft 5 is not adopted. The connecting rod, the crankshaft and other wearing parts are removed, and the maintenance is convenient. The beating-up force and the beating-up stroke of the beating-up shaft 2 are adjusted by controlling the rotation of the motor 6, so as to meet the requirements of different beating-up forces and beating-up strokes of different fabric types, and the beating-up force and the beating-up stroke of the beating-up system are realized. The application scope of the water jet and air jet loom is greatly increased.

Further, the gear box 1 is provided with a motor 3 8, and the motor 3 8 is transmission-connected with the ear wire shaft 4. By arranging motors 2 7 and 3 8 on the gear box 1 to respectively drive the opening shaft 3 and the ear wire shaft 4 to rotate, the conventional transmission mode of using a gear transmission component to drive the opening shaft 3 and the ear wire shaft 4 to rotate is not used. In this way, the rotation speed of the opening shaft 3 and the ear wire shaft 4 can be adjusted independently, thereby achieving a high rotation speed, significantly improving the efficiency of the loom. At the same time, the driving load of the main motor or the electric spindle is also greatly reduced. By controlling the transmission ratio of motor 1 6, motor 2 7, and motor 3 8, the coordinated rotation of the weft shaft 2, the opening shaft 3, and the ear wire shaft 4 is achieved. In this way, the rotation speed of the water jet loom can reach 1500-2000 rpm, which greatly improves the production efficiency of the loom, reduces the use of wearing parts such as gears, bearings, connecting rods and crankshafts, and facilitates maintenance.
