The shower pipe 31 is connected to a water pump (not shown), the water pump is started, the water pump starts pumping water, and water with a certain water pressure flows through the shower pipe 31 and then flows from the shower pipe 31 to the shower head 32. When water is sprayed out of the spray header 32, the water pressure is increased at the connection part of the spray header 32 and the spray pipe 31 and the spray opening because the spray opening is smaller than the aperture of the spray pipe 31, and the water with increased water pressure is sprayed onto the guide belt 200, so that attachments on the guide belt 200 can be washed better.

The sponge roller 50 is fixedly installed on the frame 10 at two ends and is located at one end of the frame 10. The sponge roller 50 may rotate along with the movement of the belt 200, and during the rotation of the sponge roller 50, the sponge roller 50 sucks the moisture attached to the surface of the belt 200.

For convenience of description, the spraying device 30 disposed between the first washing mechanism (or the scrubber 211) and the second washing mechanism (or the brush roller 221) is referred to as a second spraying device for wetting the belt 200 again and washing off dirt and attachments on the belt 200 after the first washing mechanism and before the second washing mechanism washes the belt 200, so that the subsequent second washing mechanism washes the belt 200.

The squeegee 40 is fixed to the frame 20. As the belt 200 moves, the squeegee 40 scrapes off the attachments and water still adhered to the surface of the belt 200 after being washed by the scrubber 211 and/or the brush roller 221.

Between the second spraying means and the scrubber 211, and between the first sponge roller 51 and the brush roller 221, there is a scraper 40 each.

For convenience of description, the squeegee 40 disposed between the sponge roller 51 and the brush roller 221 is referred to as a second squeegee; the second scraper is used for scraping off the attachments and moisture remaining on the surface of the belt 200 in a second direction perpendicular to the first direction on the surface of the belt 200 after the second washing mechanism washes the belt 200.

With continued reference to fig. 2, the frame 10 may further include a first water tank 11, a second water tank 12, and a third water tank 13, each of which is separated by a partition on the frame 10.

Referring to fig. 2, the conduction band cleaning system 100 provided by the present invention works as follows:

after the cleaning process of the belt cleaning system 100 is initiated, the belt 200 and the various components making up the belt cleaning system 100 move or rotate in the direction indicated by the dashed arrows in the figure.

The first spraying device is started, and the first spraying device sprays water towards the guide belt 200 to wet the guide belt 200, so as to prepare for the first washing process.

When the first motor 2121 is started, since the axis of the convex pillar 21211a is parallel to and not collinear with the axis of the output shaft of the first motor 2121, the rotation of the first motor 2121 is converted into the oscillation of the connecting rod 2122, the oscillation of the connecting rod 2122 is converted into the reciprocating movement of the board brush 211 along the length direction of the guide rail 2132, and the reciprocating movement of the board brush 211 can preliminarily wash dirt on the surface of the guide belt 200 and loosen attachments with high adhesive force on the surface of the guide belt 200 in the first direction.

When the scrubbing brush 211 washes the surface of the conduction band 200, the first spraying device can be started to spray water to the surface of the conduction band 200 at random according to actual working conditions, so as to clean the conduction band 200 more fully.

The first scraper scrapes off the attached matter remaining on the surface of the belt 200 together with water as the belt 200 moves, and the attached matter falls into the first water tank 11 together with the water.

And starting the second spraying device, wherein the second spraying device sprays water towards the conduction band 200 to wash away dirt and attachments remained on the surface of the conduction band 200 and moisten the conduction band 200, so as to prepare for the second washing process.

When the second motor 2221 is started, the second motor 2221 drives the brush roller 221 to rotate through the transmission 2222, and the brush roller 221 can loosen attachments with larger adhesion force on the surface of the conduction band 200 in the second direction during the rotation process, and further remove dirt on the surface of the conduction band 200.

When the brush roller 221 washes the surface of the conduction band 200, the second spraying device can be started to spray water to the surface of the conduction band 200 at random according to actual working conditions, so that the conduction band 200 can be cleaned more fully.

The second scraper scrapes off the attachments and water remaining on the belt 200 as the belt 200 moves, and the attachments and water fall into the second water tank 12 together.

As the belt 200 moves, the sponge roller 50 is also continuously rotated, and the sponge roller 50 sucks the moisture on the surface of the belt 200 while rotating.

The wringing roller 60 is also continuously rotated as the sponge roller 50 is rotated, the wringing roller 60 is rotated while squeezing out the moisture absorbed by the sponge roller 50, and the squeezed water falls into the third water tank 13.

In some embodiments, considering that the washing water falling into the first water tank 11 is turbid compared to the washing water falling into the second and third water tanks 12 and 13 when the conduction band 200 is washed, the washing water in the first water tank 11 is discharged as industrial wastewater through the water outlet pipe without being recycled in order to ensure the cleaning effect of the conduction band 200 and the printing quality of the textiles.

After the conduction band 200 is washed by the first washing mechanism, the water in the second water tank 12 and the third water tank 13 has less impurities and is relatively clear compared with the water in the first water tank 11, and on the premise of not affecting the washing effect and the textile printing quality, the water in the second water tank 12 and the third water tank 13 can be reused through the water circulation module, and the water in the second water tank 12 and the third water tank 13 cannot be replaced until the water quality (such as clarity and impurity concentration) cannot reach the standard after the washing water is used for multiple times.

According to the conduction band cleaning system 100 provided by the utility model, the attachments with large adhesive force in the first direction on the surface of the conduction band 200 are washed away through the reciprocating motion of the scrubbing brush 211 along the guide rail 2312, the attachments with large adhesive force in the second direction on the surface of the conduction band 200 are washed away through the rotation of the brush roller 221, and the omnibearing washing of the surface of the conduction band 200 is realized; the water in the first water tank 11 is discharged as waste water, and relatively clean water in the second water tank 12 and the third water tank 13 is recycled, so that the cleaning effect of the conduction band 200 and the printing quality of textiles are ensured while water is saved.

The present invention also provides a printing machine (not shown) incorporating the belt cleaning system 100.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
