[0002] A digital printing machine is a device used for large-format printing and is currently mainly used for printing and dyeing clothing fabrics.

[0003] The Chinese utility model patent currently published with the publication number CN215176715U discloses a drying roller of a digital printing machine, including a mounting frame, a collecting motor, a hot air blower and a drying roller. The drying roller is rotatably connected to the mounting frame, and a plurality of air outlet holes are opened on the drying roller. The plurality of air outlet holes are evenly distributed along the surface of the drying roller. The collecting motor is used to drive the drying roller to rotate, and the hot air blower is used to transfer heat from the plurality of air outlet holes to the fabric. In the utility model, the drying roller of the digital printing machine, hot air is blown onto the surface of the fabric through the air outlet holes, so that after the hot air is blown onto the surface of the fabric, the excess moisture in the fabric will evaporate faster.

[0004] Due to the different widths of the fabrics, when the width of the fabric is smaller than the distance between the two air outlets farthest apart along the length direction of the drying roller, some of the blowing holes on the drying roller cannot blow hot air onto the fabric, and some of the hot air directly enters the air, resulting in low heat utilization. Utility Model Content

[0005] In order to improve the utilization rate of heat during the fabric drying process, the present application provides a digital printing machine with a drying function.

[0006] The present application provides a digital printing machine with a drying function, which adopts the following technical solution:

[0007] A digital printing machine with a drying function comprises an oven, a blowing component and a control component for controlling the air volume of the blowing component, the blowing component comprises a blowing pipe and a hot air blower for supplying hot air to the blowing pipe, the blowing pipe is arranged in the oven, an air outlet slot is provided on the blowing pipe, the air outlet slot extends along the width direction of the fabric, and the control component comprises a blocking bar, the blocking bar is used to block part of the air outlet slot.

[0008] By adopting the above technical solution, the digital printing machine puts the fabric into the drying oven after printing, and the hot air blower sends hot air into the blowing pipe, and contacts the surface of the fabric through the air outlet slot to dry the dye on the surface of the fabric. When the width of the fabric is narrow, the staff can slide the blocking bar, and the blocking bar will not be able to block the air outlet slot that blows to the fabric. The length of the air outlet slot that can be used for air outlet is the same as the width of the fabric, so that the heat generated by the hot air blower can contact the fabric as much as possible, thereby improving the utilization rate of heat in the fabric drying process.

[0009] Optionally, the control component also includes a sliding block, a rotating tube, a coil spring and a locking piece, the sliding block is slidably connected to the oven along the width direction of the cloth, the rotating tube is rotatably connected in the oven, the material of the blocking bar is elastic material, one end of the blocking bar is wound on the rotating tube, and the other end of the blocking bar is arranged on the sliding block, the coil spring is arranged in the rotating tube, the coil spring is used to drive the blocking bar to retract, and the locking piece is used to limit the position of the sliding block with reference to the width of the cloth.

[0010] By adopting the above technical solution, when the cloth is narrow, the staff drives the sliding block to move, and the blocking strip originally wound on the rotating tube is pulled out to block the air outlet slot. According to the width of the cloth, it can be adjusted at any time through the sliding block. When the cloth is wider, the staff can drive the sliding block to move, and the winding spring drives the rotating tube to rotate, the rotating tube reels the blocking strip, and the locking piece locks the sliding block; the blocking strip is made of elastic material and is wound on the rotating tube, which reduces the risk of the blocking strip passing through the oven when the cloth is wider, and the blocking strip can be better retracted on the rotating tube through the winding spring.

The winding assembly has a simple structure and is easy for staff to operate.

[0013] Optionally, the locking member includes a locking strip and a locking bolt, the length direction of the locking strip is parallel to the length direction from the oven to the winding frame, one end of the locking strip is arranged on the sliding block, and the other end of the locking strip is used to abut against one end of the wound cloth on the winding roller, and the tail end of the locking bolt is threadedly connected to the locking strip and abuts against the oven.

[0014] By adopting the above technical solution, the locking bar abuts against the end surface of the cloth, and the locking bar is adjusted according to the width of different cloths. When the locking bar slides, it drives the sliding block to move, and the sliding block drives the blocking bar to move. The blocking bar will be adjusted as the locking bar moves. When the locking bar is adjusted to a suitable position, the staff can turn the locking bolt, and the tail of the locking bolt abuts against the oven. The position of the locking bar relative to the oven remains unchanged, the position of the blocking bar remains unchanged, and the locking piece has a simple and reasonable structure, which is convenient for the staff to operate.

[0015] Optionally, the blowing assembly also includes a swing part, which includes a plurality of swing blades, a plurality of matching blocks and a connecting rod. The swing blades are distributed along the length direction of the air outlet slot, and the swing blades are rotatably connected to the blowing pipe. A plurality of matching blocks correspond to a plurality of swing blades one by one. The matching blocks are arranged on the swing blades, and the length direction of the connecting rod is parallel to the length direction of the air outlet slot. The connecting rod is slidably connected to the blowing pipe along the length direction of the connecting rod, and a plurality of matching blocks are slidably connected to the connecting rod along the width direction of the connecting rod.

[0016] By adopting the above technical solution, since some fabrics have long fluff, the heat can be better contacted with the fabric through the swinging part, thereby improving the drying effect of the fabric. When the swing blade needs to swing, the staff can drive the linkage rod to slide along the length direction of the air outlet slot.

[0020] By adopting the above technical solution, when the cloth is dried and completely rolled up, the staff turns the limit bolt to make the limit bolt disengage from the winding frame, and then moves the winding motor to make the output shaft of the winding motor disengage from the winding roller. The winding roller can be removed from the winding frame. After replacing the new winding roller, the staff moves the winding motor toward the winding roller, matches the spline groove on the winding roller with the winding motor, and then fixes the winding motor with the limit bolt.
