[0024] The specific contents of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the present invention provides a cleaning device for printing ton bag cloth, including a box body 1, the top and bottom of the box body 1 are both provided with openings for cloth to pass through, two left-right symmetrical rotating drums 2 are rotatably connected in the box body 1, a group of cleaning cottons 3 distributed in a ring array are provided on the rotating drum 2, and a No. 1 motor 21 for driving the rotating drum 2 to rotate is provided on the box body 1; a liftable connecting shell 4 is provided below the rotating drum 2, a cleaning brush 41 that can reciprocate toward two ends of the cleaning cotton 3 is provided in the connecting shell 4, and a No. 1 electric telescopic rod 5 for driving the two connecting shells 4 is provided in the box body 1. The number of a group of cleaning cottons 3 on the rotating drum 2 is at least four, the number of No. 1 motors 21 is two, the main bodies of the two No. 1 motors 21 are fixed to one side of the box body 1 through the bearing strips, the rotating shaft of the No. 1 motor 21 passes through the box body 1 and is fixed to one end of the rotating drum 2, and the end of the rotating drum 2 away from the No. 1 motor 21 is open; when one end of the ton bag fabric passes through the openings at the bottom and top of the box body 1 in turn, the ton bag fabric is located between the two rotating drums 2, and then the two No. 1 motors 21 are started to drive the two rotating drums 2 to rotate, so that the cleaning cotton 3 on the right side of the left rotating drum 2 contacts one side of the ton bag fabric (with Figure 1 ), the cleaning cotton 3 on the left side of the right rotating drum 2 is in contact with the other side of the ton bag fabric; during the subsequent winding process of the ton bag fabric by the external winding device, the surface of the ton bag fabric entering the box body 1 can be effectively cleaned by the cleaning cotton 3, and the two cleaning cottons 3 cooperate with each other to clean the dust or impurities on both sides of the ton bag fabric; when the two cleaning cottons 3 are contaminated with more dust or impurities after long-term use, the two No. 1 motors 21 can be started to make the left rotating drum 2 rotate clockwise and the right rotating drum 2 rotate counterclockwise (with Figure 1The two used cleaning cottons 3 are respectively located under the two rotating drums 2; then the No. 1 electric telescopic rod 5 is started to drive the two connecting shells 4 to move upward, so that the two used cleaning cottons 3 enter the water in the two connecting shells 4 respectively, and the water surface in the connecting shells 4 slightly exceeds the top of the cleaning brush 41, so that the two cleaning brushes 41 are respectively in contact with the sides of the two cleaning cottons 3 after they are in contact with the ton bag fabric; then the two cleaning brushes 41 move back and forth (in Figure 1 The cleaning cotton 3 is then moved to the ton bag material, and the cleaning cotton 3 is ...

[0026] like Figure 3 and Figure 4 As shown, the cleaning cotton 3 is detachably connected with a connecting block 22, a connecting rod 23 penetrating the drum 2 is fixed to the connecting block 22, a fixing block 24 located in the drum 2 is fixed at one end of the connecting rod 23, a spring 25 connected to the inner wall of the drum 2 is fixed to the fixing block 24, and the connecting rod 23 is located on the inner side of the spring 25; two automatic telescopic rods 26 are provided in the drum 2 in a bilaterally symmetrical manner, and a connecting strip 27 fixed to the inner wall of the box body 1 is fixed between the fixed ends of the two automatic telescopic rods 26. When the ton bag fabric is located between the two cleaning cottons 3 (such as Figure 3 ), there is a gap between the cleaning cotton 3 and the ton bag fabric on one side thereof, and the function of the gap is to prevent the two cleaning cottons 3 from clamping the ton bag fabric and pulling it downward when the drum 2 rotates, thereby affecting the normal winding operation of the ton bag fabric after printing or coating; when the ton bag fabric is located between two adjacent cleaning cottons 3, the automatic telescopic rod 26 in the drum 2 close to the ton bag fabric is started, and the fixed block 24 close to the ton bag fabric can be pushed to squeeze the spring 25, so that the connecting rod 23 drives the cleaning cotton 3 to move through the connecting block 22, so that the cleaning cotton 3 can fully contact with the ton bag fabric; at the same time, different ton bags use different fabric thicknesses, and when cleaning thinner ton bag fabrics, the cleaning cotton 3 can be better contacted with the ton bag fabric by pushing the automatic telescopic rod 26, so as to facilitate the cleaning of the surfaces of ton bag fabrics of various different thicknesses.

[0027] like Figure 3 , Figure 6 and Figure 7As shown, the cleaning cotton 3 includes a cotton body and a plate body, the plate body is made of steel and fixed to the cotton body, a card slot is provided on the side of the plate body in contact with the connecting block 22, and a magnet 28 inserted into the card slot is fixed on the connecting block 22; a plug hole 31 is provided on the plate body, and two left-right symmetrical plug rods 6 are provided in the box body 1, and the two rotating drums 2 are respectively located between the two plug rods 6, and a No. 2 electric telescopic rod 61 for driving the plug rod 6 to vertically insert into the plug hole 31 is fixed in the box body 1 through a fixed plate, and a lifting block 62 connected to the top of the plug rod 6 is fixed at the telescopic end of the No. 2 electric telescopic rod 61; inclined inclined plates 12 are fixed on both sides of the box body 1, and discharge ports 13 located below the rotating drum 2 are provided on both sides of the box body 1, and the inclined plates 12 correspond to the discharge ports 13. When the cleaning cotton 3 is damaged after long-term use or needs to be repaired and maintained, the drum 2 can be rotated so that the two cleaning cottons 3 (a cleaning cotton 3 on the left drum 2 or a cleaning cotton 3 on the right drum 2) are respectively located under the two insertion rods 6; then the automatic telescopic rod 26 in the drum 2 away from the ton bag cloth pushes the fixed block 24 in the drum 2 away from the ton bag cloth, so that the spring 25 is compressed, and the connecting rod 23 drives the cleaning cotton 3 away from the ton bag cloth through the connecting block 22, so that the insertion hole 31 on the plate body of the cleaning cotton 3 is aligned with the insertion rod 6. 6; then the telescopic end of the second electric telescopic rod 61 drives the insertion rod 6 to move downward and insert into the insertion hole 31 through the lifting block 62, and then the telescopic end of the automatic telescopic rod 26 is restored, and the fixed block 24 is no longer pressed, so that the connecting block 22 is restored, and the magnet 28 on the connecting block 22 is separated from the cleaning cotton 3, and then the cleaning cotton 3 falls downward onto the inclined plate 12 and is discharged through the discharge port 13; the magnet 28 and the card slot are both arranged in a cross shape to increase the contact area between the magnet 28 and the plate body, so as to better adsorb and fix the cleaning cotton 3.

The No. 2 motor 7 adopts a servo motor, and the No. 1 screw rod 71 is rotatably connected to a reinforcement plate fixed on the box body 1 at one end away from the No. 2 motor 7 (the reinforcement plate is not shown in the figure); there are four groups of magnetic columns 81 on the inner side of the connecting plate 8, and the number of each group of magnetic columns 81 is two. The number of a group of cleaning cottons 3 on the rotating drum 2 is four, and the concave holes 32 on the cleaning cottons 3 are set on the plate body, and the number of corresponding concave holes 32 on the plate body of the cleaning cotton 3 is two, and the cotton body is located between the two concave holes 32; the staff can place four new cleaning cottons 3 on the bottom surface of the inner side of the connecting plate 8, and then insert the magnetic columns 81 into the concave holes 32 to adsorb the cleaning cottons 3, and the suction force of the magnetic columns 81 is less than the suction force of the magnet 28, which will not affect the rear magnet 28 to adsorb the cleaning cotton 3 and separate the cleaning cotton 3 from the magnetic columns 81. , the magnet 81 only plays a role in positioning and slightly fixing the cleaning cotton 3; when the cleaning cotton 3 is removed, the telescopic end of the automatic telescopic rod 26 pushes the fixed block 24 away from the ton bag cloth to continue to move away from the ton bag cloth, so that the connecting block 22 passes through the perforation 11, and the magnet 28 is inserted into the card slot on the cleaning cotton 3 to adsorb the cleaning cotton 3, and then the telescopic end of the automatic telescopic rod 26 is restored, and the spring 25 is restored, so that the fixed block 24 drives the connecting block 22 to restore through the connecting rod 23, and the connecting block 22 can drive the newly replaced cleaning cotton 3 into the box body 1 through the magnet 28; when other cleaning cotton 3 needs to be replaced, the rotating shaft of the No. 2 motor 7 drives the No. 1 screw rod 71 to rotate, so that the slide plate 72 drives the connecting plate 8 to move forward through the positioning rod 73, so that another new cleaning cotton 3 corresponds to the perforation 11.

[0029] like Figure 3 and Figure 5 As shown, a moving plate 42 is slidably connected in the connecting shell 4, a cleaning brush 41 is fixed on the top of the moving plate 42, and a second screw rod 43 is rotatably connected in the connecting shell 4 and is threadedly connected to the moving plate 42; two L-shaped extrusion plates 44 are fixed on the top of the moving plate 42 and the top ends extend to the outside of the connecting shell 4, and the cleaning brush 41 is located between the two extrusion plates 44. Figure 1A driving motor (not shown in the figure) is fixed to the connecting plate 42, and a servo motor can also be used for the driving motor. The rotating shaft of the driving motor is fixed to the end of the second screw rod 43. After the driving motor is started to rotate the second screw rod 43, the moving plate 42 can drive the cleaning brush 41 to move back and forth to clean the surface of the cleaning cotton 3 entering the connecting shell 4; the distance from the front to the back of the connecting shell 4 is greater than the distance from the front to the back of the cleaning cotton 3; when the cleaning cotton 3 is cleaned, it is located between the two squeezing plates 44, and the connecting rod 23 is located between the two opposite ends of the two squeezing plates 44 The top of the connecting block 22 is located below the inner top surfaces of the two squeezing plates 44; with the arrangement of the two squeezing plates 44, when the cleaning cotton 3 is cleaned, the connecting shell 4 first moves downward so that the cleaning cotton 3 is located above the squeezing plates 44, and then the driving motor is started, so that the squeezing plates 44 move with the moving plates 42 and are located directly below the cleaning cotton 3. At this time, the connecting shell 4 moves upward so that the squeezing plates 44 press against the bottom of the cleaning cotton 3, and then the moving plates 42 drive the squeezing plates 44 to move, so as to squeeze out the moisture absorbed by the cleaning cotton 3, so that the cleaning cotton 3 can be quickly dried for subsequent use.

[0030] like Figure 3 and Figure 5 As shown, the connecting shell 4 is fixed with a heater 45 located above the cleaning brush 41, and the connecting shell 4 is connected with a hose 46 that penetrates the box body 1; the telescopic end of the No. 1 electric telescopic rod 5 is fixed with a U-shaped bearing plate 51 fixed to the bottom of the connecting shell 4. After the cleaning cotton 3 is squeezed out of water, it can also enter the connecting shell 4, and then the heater 45 is started to quickly dry the cleaning cotton 3; the ton bag fabric is located on the inner side of the bearing plate 51, and after starting the No. 1 electric telescopic rod 5, the two connecting shells 4 can be driven to move upward or downward through the bearing plate 51; the hose 46 can supply water to the connecting shell 4, and the staff can also discharge the water in the connecting shell 4 through the hose 46 after disassembling the hose 46 from the external water source.

[0031] like Figure 1 and Figure 2 As shown, two symmetrical rotating rods 9 are rotatably connected in the openings at the top and bottom of the box body 1. The rotating rods 9 can assist the conveying of the ton bag fabric to avoid friction between the ton bag fabric and the inner wall of the opening of the box body 1.

[0032] like Figure 3As shown, two fixed shells 14 are fixed in the box body 1 and are symmetrically distributed. The two fixed shells 14 are inclined and located below the drum 2, and the opposite surfaces of the two fixed shells 14 are in contact with the fabric. The two fixed shells 14 can block the dust or impurities that fall down during the cleaning of the ton bag fabric by the cleaning cotton 3, so as to prevent the dust or impurities from continuing to adhere to the subsequent ton bag fabric surface; at the same time, after a circular hole is opened on the top surface of the fixed shell 14, the exhaust end of the external exhaust fan is connected to the fixed shell 14, so that the dust or impurities that fall down from the ton bag fabric can be sucked through the circular hole and discharged to the outside of the box body 1.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
