Description
Technical Field
The invention belongs to a water jet loom in the field of spinning, and particularly relates to a water pressure adjustable weft insertion water pump of the water jet loom.
Background
The water jet loom is suitable for weaving chemical fiber filament fabric, and high pressure water flow pulls weft yarns to pass through a shed to realize weft insertion weaving.
The outer contour shape of the cam is fixed, so that the compression amount of the spring cannot be changed at will to adjust the water pressure, and in actual production, the water pressure also needs to be adjusted due to the change of the width of the fabric, for example, the width is reduced. The water pressure is correspondingly reduced to save energy, the water pressure is increased when the fabric width is increased, otherwise, the weft insertion is not finished or delay is delayed due to insufficient water pressure.
Furthermore, if the linear density of the weft thread is high, the required weft insertion water pressure is also increased, otherwise the weft insertion traction force is insufficient. If the weaving machine speeds are different, the water pressure can be lower because the water pressure should be adjusted accordingly, i.e. the weft insertion speed can be slower, and if the weaving machine speed is higher, the water pressure is increased accordingly, so that the weft threads pass through the shed as quickly as possible.
In summary, the conventional cam-type weft insertion device is only suitable for fabrics with fixed width, fixed speed and small variation range of weft thread density.
Disclosure of Invention
The purpose of the invention is as follows: in order to solve the defects of the prior art, the invention provides a water pressure adjustable weft insertion water pump of a water jet loom.
The technical scheme is as follows: the weft insertion water pump of the water jet loom with adjustable water pressure comprises a water pumping process and a water spraying process, wherein the water pumping process comprises the following steps:
the motor drives the lower toothed belt wheel to rotate anticlockwise through the reducer, the toothed belt wheel drives the intermittent toothed belt, when a toothed area I of the toothed belt rotates anticlockwise and is meshed with outer teeth of the toothed belt of the through teeth, the inner teeth of the toothed belt drive the toothed wheel to rotate clockwise, and when the toothed belt wheel rotates, the wheel coaxial with the toothed belt wheel is driven to rotate clockwise around an angular rod shaft by pulling an angular rod connected with the wheel through a nitrile rubber belt, so as to drive a connecting rod and a connected piston to move outwards, pull an inner spring seat fixedly arranged on the wheel to slide along the surface of a cylinder sleeve, and compress a spring; at the moment, water passes through a space between a water inlet valve piston in the pump body and the cylinder sleeve from the water tank due to the action of negative pressure, so that the process of pumping water is realized;
the water spraying process is as follows:
when the toothless area II of the intermittent toothed belt rotates anticlockwise to the outer teeth of the toothed belt with the through teeth, because the toothed belt has no teeth, the toothed belt cannot rotate under the meshing action to form a 'free stroke', namely, the toothed wheel cannot be driven to rotate clockwise through the belt wheel to drive the angle-pulling rod under the nitrile rubber belt, namely, the spring is not compressed any more, and on the contrary, under the action of elastic potential energy recovery of the spring, the angle-pulling rod rotates anticlockwise around the shaft of the angle-pulling rod to drive the connecting rod and the connected piston to move inwards, so that 'water spraying' is realized.
As an optimization: adjusting water pressure: the water pressure can be changed by changing the tooth number of the intermittent toothed belt, and the longer the toothed area is, the larger the moving stroke of the piston relative to the cylinder sleeve is, the larger the compression amount of the spring is, the larger the water pressure is, and the limitation of the maximum moving stroke of the machine is certainly realized.
As an optimization: adjusting the water spraying time: and the water spraying and weft insertion time is determined by changing the meshing position of the first teeth and the external teeth of the toothed belt of the through teeth when the transmission interrupted toothed belt tooth area I rotates anticlockwise.
As an optimization: the teeth of the toothed belt are inserted by a movable sleeve method, each movable tooth is inserted between the upper and lower bottom plates of the outer toothed belt and fixed by a positioning screw, a reinforcing rib is arranged between the upper and lower bottom plates of the toothed belt to increase the toughness of the toothed belt, and continuous teeth which are formed in one step are arranged on the inner side of the toothed belt and are used for being meshed with the teeth of the upper and lower toothed belt wheels to play a role in transmission.
Has the advantages that: the invention adopts an intermittent tooth-shaped belt type transmission angle rod rotation mode, has stable movement, high reliability, high transmission efficiency, good maintenance-free performance, easy installation and debugging and can adjust the swing amplitude of the angle rod so as to adjust the stroke of the piston relative to the cylinder sleeve, thereby changing the compression amount of the spring and achieving the purpose of adjusting the water pressure.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below so that those skilled in the art can better understand the advantages and features of the present invention, and thus the scope of the present invention will be more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
Examples
As shown in fig. 1, the principle of the water spray pump of the present invention is as follows: in the process of the rotation of the cam 3 from a small semi-radial direction to a large radius, the rotor of the angular lever 1 is pressed to rotate clockwise around the shaft of the angular lever, the connecting rod 14 and the connected piston 8 are driven to move outwards (namely, the left side in the figure), the spring inner seat 6 fixedly arranged on the connecting rod is pulled to slide along the surface of the cylinder sleeve 7, and the spring 5 is compressed. At this time, due to the negative pressure, water flows from the water tank 16 through the space between the piston of the water inlet valve 10 in the pump body and the cylinder sleeve, so that the process of pumping water is realized.
When the cam 3 rotates from a large radius to a small radius, the rotor of the angular lever 1 can rotate anticlockwise around the shaft of the angular lever due to the reduction of the radius, the connecting rod 14 and the connected piston 8 are driven to move inwards quickly due to the release of elastic potential energy of the compressed spring 5, and water in the space between the piston and the cylinder sleeve is sprayed out along the water outlet valve 9 under the pushing of the piston, so that the water spraying and weft insertion are realized.
The invention adopts a mode of intermittent tooth-shaped belt type transmission angle rod 1 rotation, has stable movement, high reliability, high transmission efficiency, good maintenance-free performance, easy installation and debugging and can adjust the swing amplitude of the angle rod, thereby adjusting the stroke of the piston 8 relative to the cylinder sleeve 7, changing the compression amount of the spring 5 and achieving the purpose of adjusting the water pressure.
1. Water pumping process
As shown in fig. 2, a toothed belt wheel a rotates anticlockwise under the drive of a motor through a speed reducer, the toothed belt wheel drives an intermittent toothed belt b, when a toothed area I rotates anticlockwise to be meshed with an external tooth of a toothed belt c with through teeth (namely all the teeth on the toothed belt), the internal tooth of the toothed belt drives a toothed wheel d to rotate clockwise, when the toothed belt wheel rotates, a windlass belt wheel 5 coaxial with the toothed belt wheel is driven to rotate clockwise around an angular rod shaft by pulling an angular lever 1 connected with the toothed belt wheel through a nitrile rubber belt f, a connecting rod 14 and a connected piston 8 are driven to move outwards (namely the left side in the figure), a spring inner seat 6 fixedly arranged on the connecting rod is pulled to slide along the surface of a cylinder sleeve 7, and the spring 5 is compressed. At this time, due to the negative pressure, water flows from the water tank 16 through the space between the piston of the water inlet valve 10 in the pump body and the cylinder sleeve, so that the process of pumping water is realized.
2. Water spraying process
When the toothless area II of the intermittent toothed belt b rotates anticlockwise to the outer teeth of the toothed belt c with the through teeth, because b has no teeth, the toothed belt c cannot rotate under the meshing action to form a 'free stroke', namely, the toothed wheel d cannot be driven to rotate clockwise through the belt wheel to drive the lower stretching angle rod of the nitrile rubber belt, namely, the spring 5 is not compressed any more, and on the contrary, under the action of elastic potential energy recovery of the spring, the angle-shaped lever 1 rotates anticlockwise around the shaft thereof to drive the connecting rod 14 and the connected piston 8 to move inwards (namely, the right side in the figure), so that 'water spraying' is realized.
3. Regulation of water pressure
The water pressure can be changed by changing the tooth number of the intermittent toothed belt, and the longer the toothed area is, the larger the moving stroke of the piston 8 relative to the cylinder sleeve 7 is, the larger the compression amount of the spring 5 is, the larger the water pressure is, and the maximum moving stroke of the machine is also limited.
4. Water spray time adjustment
The water spraying and weft insertion time is determined by changing the meshing position of the first teeth and the outer teeth of the toothed belt c with the through teeth (namely all the teeth on the toothed belt) when the toothed area I of the transmission interrupted toothed belt b rotates anticlockwise.
5. Tooth mounting combination of toothed belt
The teeth of the toothed belt are inserted by a loop, as shown in figure 3, each movable tooth 01 is inserted between the upper and lower bottom plates 02 of the outer toothed belt and fixed by a positioning screw 04, a reinforcing rib 03 is arranged between the upper and lower bottom plates of the toothed belt to increase the toughness of the toothed belt, and the inner side of the toothed belt is provided with continuous teeth 05 which are formed in one step and used for being meshed with the teeth of the upper and lower toothed belt wheels in figure 1 to play a transmission role.
The intermittent toothed belt of the loop inserting method is convenient for changing the number and the position of teeth, and can be conveniently taken out or adjusted according to the process requirements.
