Description

Technical Field

[0001] The present invention relates to the field of digital printing, and particularly to a rotary digital printing machine and a control method thereof. Background Art

[0002] A digital printing machine is a precision device used in fields such as textiles and decorative materials. Its core structure usually includes a rotating mechanism, a printing device, and a drying device. The rotating mechanism is responsible for carrying and transporting the material to be printed. The printing device sprays ink onto the material surface through a high-precision print head to complete pattern printing. The drying device is used to quickly cure the ink to ensure the clarity and durability of the pattern. However, in the existing design, since the rotating mechanism is arranged in a horizontal cross shape, the drying device and the printing device are usually arranged at a right angle, so that the drying area and the printing area are also arranged at a right angle. This layout leads to the problem of excessive space occupation of the whole machine. Especially in the case of limited space in the production workshop, it restricts the flexible deployment and efficient utilization of the equipment.

[0003] According to the above, the existing digital printing machine needs to be further improved. Summary of the Invention

[0004] The first object of the present invention is to overcome the deficiencies in the structural design of the existing digital printing machine, and provide a digital printing machine in which the material receiving roller group is arranged and rotated in the vertical direction, so that the printing area and the drying area can be arranged parallel to each other, and the overall structure of the machine is more compact and space-saving.

[0005] To achieve the above object, the present invention adopts the following technical solution: A rotary digital printing machine includes a carrying device, the carrying device includes a material receiving roller group, the material receiving roller group includes at least 4 material receiving rollers, the material receiving rollers are arranged in a cross shape and extend along the X-axis direction; a printing device, the printing device is arranged on one side of the carrying device to form a printing area; a drying device, the drying device is arranged on the carrying device to form a drying area; the material receiving roller group can rotate along a vertical plane, so that the material receiving rollers enter the printing area and the drying area in turn.

[0006] By arranging the material receiving roller group to extend along the X-axis direction and setting it to rotate along a vertical plane, the printing area and the drying area can be arranged parallel to each other in the horizontal direction. This not only optimizes the space layout of the equipment, but also greatly improves the compactness of the structure. Compared with the prior art, the rotary digital printing machine of the present invention has a more compact structure and a smaller space occupancy rate.

[0007] Preferably, the carrying device includes a frame, a base and a turntable. The base is movably arranged on the frame. A driving device is arranged on the base and is in transmission connection with the turntable, so that the material receiving roller circulates and transfers between the printing area and the drying area. The material receiving roller group further includes a driving motor. The material receiving rollers and the driving motors are evenly distributed on the turntable, and the driving motors are in transmission connection with the material receiving rollers. The driving motor located in the printing area is electrically connected and powered through an electricity connection part, and the driving motor located in the drying area is not powered on.

[0008] Preferably, a power supply part is arranged on the base, and a plurality of electricity connection parts are arranged on the turntable. When at least one material receiving roller enters the printing area and the power supply part abuts against the corresponding electricity connection part, the driving motor located in the printing area is powered on to make the material receiving roller rotate. Since the inkjet printing position of the printing device is fixed, during the operation of the printing device, the material cylinder located in the printing area needs to rotate. After the material receiving roller located in the printing area is in abutting connection with the power supply part through the corresponding electricity connection part and is powered on, it can rotate and drive the material cylinder to rotate, thereby completing printing.

[0009] Preferably, the electricity connection part is arranged on the turntable and behind the material receiving roller, the power supply part is arranged at the lower part of the base, and the plurality of electricity connection parts are in staggered electrical connection with the plurality of material receiving rollers; or the material receiving roller is electrically connected with the corresponding electricity connection part at the rear side, and the power supply part is arranged at the side part of the base.

[0010] Preferably, the drying device includes a bracket and a heating part. The bracket is erected above the material receiving roller group, and the heating part is arranged on the bracket and in the middle of the turntable. The heating surface of the heating part faces upward or downward, which can make full use of the vertical space and reduce the occupation of the factory building area by the whole machine.

[0011] Preferably, there are two heating parts, and the heating surfaces of the two heating parts are arranged opposite to each other at a certain distance, and the material receiving roller can rotate into the space between the two heating parts.

[0012] Preferably, a magnetic driving structure is arranged on the turntable. The magnetic driving structure includes a rotatable magnetic connection part. The magnetic connection part is arranged in the drying area. When at least one material receiving roller enters the drying area, the magnetic connection part is in magnetic induction coupling with the material receiving roller. Since the power supply part does not abut against the electricity connection part of the material receiving roller located in the drying area, the power supply part cannot supply power to it to make it rotate. The magnetic connection part is used to make the material receiving roller located in the drying area rotate through magnetic induction coupling, and the drying is more uniform.

[0013] Preferably, the base includes a mounting bottom plate and a mounting seat. The mounting bottom plate is slidably arranged on the frame, and the mounting seat is arranged on the mounting bottom plate and can move up and down through a lifting structure.

[0014] Preferably, the lifting structure includes a jacking part and a rocking wheel, and the rocking wheel is in transmission connection with the jacking part, so that the jacking part moves up and down to drive the mounting seat to rise or fall, and the height of the whole machine can be adjusted according to the size of the material cylinder for the height of the base.

[0015] Another object of the present invention is to provide a control method, including: placing the material cylinder on the receiving roller and sleeving the material to be printed; the base moves away from the printing device, and the turntable rotates to make the material cylinder sleeved with the material to be printed enter and stay in the printing area; the base moves towards the printing device to make the material cylinder correspond to the printing device and start printing; the base moves away from the printing device again, and the turntable rotates to transfer and switch the printed material cylinder out of the printing area and make the new material cylinder to be printed enter the printing area. Compared with the prior art, due to the application of the above scheme, the control method of the present invention makes the structure of the rotary digital printing machine combined with it more compact and has a smaller space occupancy rate.

[0026] Embodiment 1

[0027] See Figures 1 to 2 , this embodiment discloses a rotary digital printing machine 1, including a carrying device 3. The carrying device 3 includes a material receiving roller group 4. The material receiving roller group 4 includes at least 4 material receiving rollers 41. The material receiving rollers 41 are arranged in a cross shape and extend along the X-axis direction; a printing device 5 is provided on one side of the carrying device 3 to form a printing area 51; a drying device 6 is provided on the carrying device 3 to form a drying area 61. The material receiving roller group 4 can rotate along the vertical plane, so that the material receiving rollers 41 take turns to enter the printing area 51 and the drying area 61 in sequence.

[0028] See Figures 1 to 6 , the carrying device 3 includes a frame 31, a base 32 and a turntable 33. The base 32 is movably provided on the frame 31. A driving device 321 is provided on the base 32, and the driving device 321 is in transmission connection with the turntable 33. The material receiving roller group 4 further includes a driving motor 42. The material receiving rollers 41 and the driving motor 42 are evenly distributed on the turntable 33, and the driving motor 42 is in transmission connection with the material receiving rollers 41. In the solution of this scheme, the driving motor 42 is electrically connected to the material receiving rollers 41. When the material receiving roller 41 is located in the printing area 51, the driving motor 42 is powered on through the driving device 321 and then drives the material receiving roller 41 to rotate, cooperating with the printing device 5 to complete printing.

[0029] See Figures 4 to 5 , in order to supply power to the material receiving roller 41 located in the printing area 51 to make it rotate self - sufficiently and achieve rolling printing, a power supply part 322 is provided on the base 32, and a number of power receiving parts 331 are provided on the turntable 33. When at least one material receiving roller 41 enters the printing area 51 and the power supply part 322 abuts against the corresponding power receiving part 331, the driving motor 42 located in the printing area 51 is powered on to make the material receiving roller 41 rotate.

[0030] See Figures 4 to 5, the power connection part 331 is arranged on the turntable 33 and behind the material receiving roller 41, the power supply part 322 is arranged at the lower part of the base 32, and the plurality of power connection parts 331 are electrically connected to the plurality of material receiving rollers 41 in a staggered manner; or the material receiving roller 41 is electrically connected to the corresponding power connection part 331 at the rear side, and the power supply part 322 is arranged at the side part of the base 32. The position setting of this solution enables the power supply part 322 to be in contact with the power connection part 331 that can be electrically connected to the printing area 51 by horizontal movement, without the need for vertical movement, simplifying the machine operation steps.

[0031] See Figures 1 to 5 , the drying device 6 includes a bracket 62 and a heating part 63. The bracket 62 is erected above the material receiving roller group 4, and the heating part 63 is arranged on the bracket 62 and in the middle of the turntable 33. The heating surface of the heating part 63 faces upward or downward. In this solution, the heating parts are arranged opposite to each other up and down. On the one hand, it enables the material receiving roller 41 to turn into and out of the drying area 61, and on the other hand, it can make full use of the vertical space and reduce the floor area occupied by the whole machine in the factory building.

[0032] See Figures 1 to 2 , to enclose the baking heat of the drying area 72 and improve the drying efficiency, there are two heating parts 63. The heating surfaces of the two heating parts 63 are arranged opposite to each other at a certain distance, and the material receiving roller 41 can rotate into the space between the two heating parts 63. Specifically, the drying device 6 further includes a baffle 64. The bracket 62 is arranged on the base 32, and the baffle 64 is arranged on both sides of the heating part 63 so as to be movable up and down.

[0033] See Figures 1 to 3 , a magnetic driving structure 332 is arranged on the turntable 33. The magnetic driving structure 332 includes a rotatable magnetic connection part 3321. The magnetic connection part 3321 is arranged in the drying area 61. When at least one material receiving roller 41 enters the drying area 61, the magnetic connection part 3321 is magnetically inductively coupled with the material receiving roller 41. Specifically, a magnetic wheel is arranged inside the material receiving roller 41. In this solution, the magnetic connection part 3321 drives the magnetic wheel to rotate through magnetic force, so that the magnetic wheel drives the material receiving roller 41 located in the drying area 61 to rotate, thereby driving the materials on the material receiving roller 41 to rotate, with more uniform drying and higher drying efficiency. At the same time, the non-contact driving of the magnetic driving structure 332 on the material receiving roller 41 makes the rotation of the material receiving roller 41 smoother.
