[0002] The rope washing machine comprises at least two washing tanks through which the fabric will pass. In practice, the fabric is supplied from the outside of the first washing tank, where the fabric is accumulated, and from the first washing tank, through the first conveying duct, it leads to the area provided with the rotating fabric guide tube; from this area, the fabric passes through the second conveying duct to the second washing tank, and leaves the machine from here (in the case of only two washing tanks). In order to ensure the smooth transportation of the fabric between two adjacent washing tanks, a cloth lifting wheel is usually used to drive it at a certain rotation speed. The conveying duct is a duct through which the rope-shaped fabric passes, and the pressurized washing liquid is introduced into the duct in the same direction as the forward direction, thereby driving the fabric, and the fabric guide tube rotates in the same direction as the fabric movement, but the current sensor system for controlling the fabric movement direction (i.e. controlling the forward and reverse rotation of the cloth lifting wheel) has a poor application effect, and the current nozzle fabric guide tube device is not flexible in swinging, which makes the nozzle fabric guide tube device have a poor washing effect and is easy to cause damage to the fabric during the rinsing process.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "surface", "side", "inside", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0019] like Figure 1-2 As shown, a swingable nozzle fabric guide pipe device includes a nozzle assembly 1 arranged in a water washing machine and a fabric guide pipe assembly 2 pivotally connected to the lower part of the nozzle assembly 1 body. Specifically, both ends of the nozzle assembly 1 body are fixedly connected with brackets 11, and a pin shaft 111 is installed on the bracket 11. The first tube body 21 is pivotally connected to the pin shaft 111, and then the first tube body 21 rotates with the pin shaft 111 as the rotation axis.

[0020] The fabric guide tube assembly 2 includes a first tube body 21 for inserting the lower part of the nozzle assembly 1 body, and the first tube body 21 is tilted to the first position 3 under the traction of the fabric. The fabric guide tube assembly 2 also includes an elastic member 221 for pulling the first tube body 21 back to the second position 4. In the present invention, the elastic member 221 is a spring. A magnetic sensor 5 is fixedly installed on the washing machine, and a magnet 51 that cooperates with the magnetic sensor 5 for induction is installed on the first tube body 21. When the first tube body 21 rotates to the first position 3, the magnet 51 is located in the action area 52 of the magnetic sensor 5. When the first tube body 21 rotates to the second position 4, the magnet 51 is located outside the action area 52 of the magnetic sensor 5.

[0021] The angle between the first position 3 and the second position 4 is a, and the first tube body 21 does not interfere with the lower part of the nozzle assembly 1 body within the rotation range of the angle a, that is, the first tube body 21 does not collide with the third tube body 13 within the rotation range of the angle a, and the maximum rotation angle a of the first tube body 21 is controlled by the pulling force of the driving device (not shown in the figure) and the elastic force of the elastic member 221.

[0022] The nozzle assembly 1 body is connected to a base frame 22, one end of the elastic member 221 is connected to the base frame 22, and the other end of the elastic member 221 is connected to the first tube body 21.

When the first tube body 21 rotates to the second position 4, it abuts against the buffer pad 23. By providing the buffer pad 23, a supporting force is generated when the first tube body 21 is reset to the second position 4, thereby preventing the first tube body 21 from swinging too much to the left and playing a certain buffering role.

[0024] The nozzle assembly 1 includes a second tube body 12 with a chamber therein and a third tube body 13 with one end extending into the chamber and sealingly matched with the second tube body 12. The second tube body 12 is provided with a feed inlet 121 and a liquid inlet. The feed inlet 121 is provided with an interface portion 122 which is close to the third tube body 13 inward in the length direction. The end of the third tube body 13 close to the interface portion 122 is provided with an interface portion 2 131 arranged on the outer periphery of the interface portion 122. A jet gap 15 is formed between the interface portion 122 and the interface portion 2 131. One end of the second tube body 12 relative to the interface portion 122 is fixedly connected with a plurality of circumferentially arranged bolts 123, and each bolt 123 is provided with a nut group 124. The end of the third tube body 13 extending out of the chamber is provided with a connecting ring 125 which is installed in cooperation with the bolt 123. The position of the nut group 124 on the corresponding bolt 123 is adjusted to adjust the size of the jet gap 15.

[0025] An annular platform 126 is protruded inwardly at one end of the second tube body 12 close to the bolt 123, and the annular platform 126 is sealed with the third tube body 13. Specifically, two sealing grooves are arranged at intervals on the inner wall of the annular platform 126, and a sealing ring 127 is arranged in the sealing groove to seal against the tube wall of the third tube body 13.

[0026] The second tube body 12 includes a cavity portion with a chamber therein and a nozzle portion with an interface portion 122, and the cavity portion is sealed and connected to the nozzle portion.

[0027] A swingable nozzle fabric guide pipe device, wherein washing liquid penetrates and rinses fabric through the nozzle gap and guides the fabric to the first tube body 21, the fabric is lifted under the traction of a driving device (not shown in the figure), and a traction force is generated by the upward thrust of the fabric to drive the first tube body 21 to the first position 3, at which time the magnet 51 is located in the action area 52 of the magnetic sensor 5, at which time the movement is detected and the signal is sent to the control component, the signal controls the forward and reverse rotation of the cloth lifting wheel to achieve cloth piling control, when the driving device does not generate traction on the fabric, the first tube body 21 is reset to the second position 4 under the elastic force of the elastic member 221, at which time the first tube body 21 is in the same vertical line as the second tube body 12 and the third tube body 13, at which time the magnet 51 is located outside the action area 52 of the magnetic sensor 5, through the above arrangement, the nozzle fabric guide pipe device plays a role in protecting the fabric when swinging the fabric, and at the same time provides a signal to control the forward and reverse rotation of the cloth lifting wheel to achieve cloth piling control, thereby making the nozzle fabric guide pipe device less damaging to the fabric when guiding the fabric and having a better washing effect on the fabric.
