Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0028] It should be noted that the reciprocating motor is a linear reciprocating motor.

[0029] Embodiment 1

[0030] As Figure 1 , Figures 3-6 shown, a cloth leveling device, including digital printer 1, the digital printer 1 is installed for conveying cloth conveying belt 2, conveying belt 2 surface has adhesion, the printing head in digital printer 1 is located above the middle part of conveying belt 2, conveying belt 2 front side above rotationally connected with conveying roller 3, conveying belt 2 above between printing head and conveying roller 3 installs for removing the hair of cloth hair removal assembly, conveying roller 3 above rotationally connected with the leveling roller 4 for leveling cloth, the leveling roller 4 is rotationally connected on digital printer 1.

[0031] The leveling roller 4 side is installed with driving motor 20, and the driving motor 20 is fixedly connected on the digital printer 1, and the output end of the driving motor 20 drives the leveling roller 4 to rotate through the synchronous belt, and the outer circumferential surface of the leveling roller 4 is provided with two thread-like smooth protrusions 18 along the axial symmetry, the rotation directions of the two protrusions 18 are opposite, the leveling roller 4 is driven to rotate through the driving motor 20, when the leveling roller 4 rotates, the two protrusions 18 with opposite rotation directions drive the wrinkles on the cloth to flatten outward, so that the cloth is flattened.

[0032] The depilation assembly comprises a negative pressure chamber 5 installed horizontally above the conveying belt 2 and a shearing mechanism installed in the negative pressure chamber 5, a gap is left between the bottom end of the negative pressure chamber 5 and the conveying belt 2 for the cloth to pass through, an air inlet 6 is formed on the front side of the bottom end of the negative pressure chamber 5, the shearing mechanism comprises a lower cutter head 7 fixedly connected in the negative pressure chamber 5, an upper cutter head 8 slidably connected on the lower cutter head 7 and a reciprocating motor 9 driving the upper cutter head 8 to reciprocate on the lower cutter head 7, the reciprocating motor 9 is installed in the negative pressure chamber 5, the lower cutter head 7 is located on the side of the air inlet 6 away from the conveying roller 3, and the lower cutter head 7 and the upper cutter head 8 are both provided with sawteeth on the side close to the air inlet 6, the length direction of the lower cutter head 7 and the upper cutter head 8 is parallel to the axis of the conveying roller 3, and the upper cutter head 8 is driven to move by the reciprocating motor 9 to cooperate with the lower cutter head 7 to form shearing to cut the thread bundle;

[0033] After the cloth is moved by the conveying belt 2 to below the air inlet 6 of the negative pressure chamber 5, the thread bundle on the cloth is sucked upward and leaks out of the connection under the influence of negative pressure, and as the cloth continues to move, the connection between the thread bundle and the cloth is cut off by the shearing mechanism, and the thread bundle is then sucked away by the negative pressure.

[0034] The working principle is that the cloth is first adhered to the conveying belt 2 after being turned by the flattening roller 4 and the conveying roller 3 (a series of transmission rollers are arranged in front of the flattening roller 4 for transmission and turning, which will not be described here; the conveying belt surface has slight adhesion to keep the cloth flat during movement), and the cloth moves forward with the conveying belt 2, when the cloth has wrinkles or edge folds, the wrinkles and edge folds on the cloth are unfolded by the convex 18 rotating in the opposite direction and rotating when the cloth passes through the flattening roller 4, the flattening roller 4 is located above the conveying roller 3, so that the cloth directly passes through the conveying roller 3 to the conveying belt 2 after being flattened, avoiding the reappearance of wrinkles and edge folds; when there is a thread bundle on the cloth, the thread bundle is sucked upward and leaks out of the connection with the cloth under the influence of negative pressure when the thread bundle passes below the negative pressure chamber 5, the reciprocating motor 9 works to drive the upper cutter head 8 to reciprocate and cooperate with the lower cutter head 7 to cut off the connection between the thread bundle and the cloth, and the cut thread bundle leaves the cloth under the action of negative pressure.

[0035] In combination with the above, the flattening roller 4 is used to flatten the wrinkles and edge folds of the cloth, and the depilation assembly removes the thread bundle on the surface of the cloth, so that the cloth surface is flat and passes below the printing nozzle, effectively solving the problem that the cloth is not flat during printing, which affects the printing effect.

[0036] Example 2

[0037] As Figures 1-4As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. Since there may be broken threads still on the cloth after the ball of yarn is cut by the shearing structure, an adsorption port 10 is opened on the rear side of the bottom end of the negative pressure chamber 5. The adsorption port 10 can be opened to adsorb the remaining debris on the cloth again to ensure that there are no broken threads on the cloth.

[0038] In order to increase the negative pressure adsorption effect, in this embodiment, a negative pressure channel 11 is provided in the negative pressure chamber 5. The negative pressure channel 11 is in the shape of an inverted funnel. The upper end of the negative pressure channel 11 is connected to an induced draft fan 12. A debris box 13 is installed between the induced draft fan 12 and the negative pressure channel 11. A filter 14 for separating the induced draft fan 12 and the negative pressure channel 11 is installed in the debris box 13. A door is provided on the debris box 13. The filter 14 is set to intercept the yarn balls. After a period of time, the door on the debris box 13 is opened to take out the accumulated yarn balls.

[0039] Example 3

[0040] like Figures 1-4 As shown, the structure of this embodiment is roughly the same as that of Example 2. This embodiment is further optimized on the basis of Example 2. Since the fabrics are thick and thin, in order to facilitate the removal of yarn balls for fabrics of different thicknesses, adjustment frames 15 are installed at both ends of the negative pressure chamber 5. The adjustment frame 15 is fixedly connected to the digital printer 1. The adjustment frame 15 is U-shaped. Both ends of the negative pressure chamber 5 are fixedly connected to adjustment blocks 16 that are slidably connected to the adjustment frame 15. The adjustment block 16 is threadedly connected to an adjustment bolt 17 perpendicular to the bottom of the adjustment frame 15, and the bottom of the adjustment bolt 17 is rotatably connected to the adjustment frame 15.

[0041] The negative pressure chamber 5 can be raised or lowered by rotating the adjusting bolts 17 at both ends of the negative pressure chamber 5 to adapt to fabrics of different thicknesses.

[0042] Because the occurrence of yarn balls is rare, in order to prevent the draft fan 12 and the reciprocating motor 9 from idling for a long time, photoelectric sensors 19 are installed on both sides of the front side of the dehairing component. The photoelectric sensor 19 includes a transmitter and a receiver. The photoelectric sensor 19 is set to detect whether there are yarn balls on the fabric.

[0043] As a conventional technical means for those skilled in the art, a controller can be installed on the digital printer 1, and the drive motor 20, reciprocating motor 9, induced draft fan 12 and photoelectric sensor 19 are all electrically connected to the controller. The drive motor 20 runs for a long time. When the photoelectric sensor 19 detects that a ball of thread passes by, the reciprocating motor 9 and the induced draft fan 12 start working and automatically stop after working for a period of time (the working time can be determined according to the moving speed of the fabric and the distance between the photoelectric sensor 19 and the negative pressure chamber 5).
