Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and in particular to a distributed intelligent combination device for a nozzle of a digital printing machine. Background Art

[0002] Digital printing press is a modern printing technology equipment that prints images or text directly on paper, plastic, metal and other media through digital signals without using traditional film or printing plate. This technology greatly simplifies the printing process, improves efficiency, and reduces the cost of small-batch printing.

[0003] There are two common digital printing methods. One is scanning, which uses a print head that moves back and forth. The cardboard is stationary during printing and moves forward after completion. Due to the working principle of stepping, the speed is slow but the printing quality is high. The other is a one-time pass, where the nozzle does not move and the cardboard does not stop throughout the process. It moves forward at a certain speed, so the speed is high, but the printing accuracy is average. These two printing methods have their own advantages and disadvantages. In existing equipment, a printer usually only uses one of the printing methods, and it is impossible to switch accordingly according to the specific usage scenario. Utility Model Content

[0034] The working principle and beneficial effects of the utility model are:

[0035] In the utility model, the chassis bears the entire weight of the device, and at the same time increases the contact area between the device and the ground, ensuring that the device can be stably operated and placed. The conveying device is used to convey the cardboard, ensuring that the pattern on the cardboard can be automatically printed through the conveying device, simplifying the printing operation and improving the printing quality.

DETAILED DESCRIPTION

[0046] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0047] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] Reference Figure 1 to Figure 8, which is the first embodiment of the utility model, proposes a distributed intelligent combination device of a digital printing machine nozzle 320, including: a conveying device 2 is arranged on a base frame 1, and the conveying device 2 is used to convey paperboard; a printing head 3 is slidably arranged on the base frame 1, and the sliding direction of the printing head 3 is perpendicular to the conveying direction of the conveying device 2; there are a plurality of turntables 310, which are rotatably arranged on the printing head 3; there are a plurality of nozzles 320, and the plurality of nozzles 320 are arranged in an array at intervals on the turntable 310. After the turntable 310 rotates, the plurality of nozzles 320 on the turntables 310 are combined into a row or canceled from being combined into a row.

[0050] In this embodiment, the chassis 1 bears the entire weight of the device, and at the same time increases the contact area between the device and the ground, ensuring that the device can operate and be placed stably. The conveying device 2 is used to convey the cardboard, ensuring that the pattern on the cardboard can be automatically printed through the conveying device 2, simplifying the printing operation and improving the printing quality. The printed pattern is directly sprayed onto the cardboard through the nozzle 320. There are two spraying forms of the printer. When the turntable 310 rotates, the nozzles 320 are combined into a row. At this time, the direction of the entire row of nozzles 320 is perpendicular to the conveying direction of the conveying device 2. The entire row of nozzles 320 can cover the cardboard, and the cardboard can be sprayed through the continuous conveying of the conveying device 2. This printing method is a one-time pass type. Since the cardboard is in the form of continuous conveying, the printing speed is fast, and a large amount of printing can be completed in a short time. When the turntable 310 rotates, the combination of the nozzles 320 will change, so that the direction of the nozzles 320 is the same as the direction of the cardboard conveying. At this time, the conveying device 2 will switch the conveying mode to intermittent conveying, and the sliding of the printing head 3 will ensure the integrity of the pattern printing. Since the cardboard conveying mode has changed, the time required for printing will increase, but at the same time the printing quality will increase. This printing method is scanning. By changing the arrangement of the nozzles 320 through the rotation of the turntable 310, the printing method is changed. When using the printer, the user can freely hang the printing method according to the actual situation, which improves the adaptability of the printer.

[0051] Furthermore, it also includes: a first gear 330 is set on the turntable 310; a second gear 340 is rotatably set on the printing head 3, and the second gear 340 is meshed with the first gear 330; a first driving member 350 is set on the printing head 3, and the first driving member 350 is used to drive the second gear 340 to rotate.

[0052] In this embodiment, the first gear 330 is set on the turntable 310. When the first driving member 350 is in motion, it will drive the second gear 340 to rotate. When the second gear 340 rotates, it will rotate the first gear 330 meshing with it, so that the turntable 310 rotates and the combination state of the nozzle 320 is changed. Through the design of the gear and the driving member, the combination mode of the nozzle 320 can be automatically switched, which simplifies the operation and improves the user's experience. The first driving member 350 is a motor, and can also be a motor or other form that can drive the gear to rotate, to ensure the stability of the rotation of the second gear 340, thereby improving the overall stable operation of the device.

[0053] Further, the conveying device 2 includes: a conveyor belt 210 is arranged on the base frame 1, and the conveyor belt 210 is used to place the cardboard and convey it; there are a plurality of conveying rollers 220, which are rotatably arranged on the base frame 1; there are a plurality of third gears 230, which are arranged at both ends of the conveying roller 220; a ratchet 240 is arranged on the conveying roller 220, and the ratchet 240 is used to control the rotation state of the conveying roller 220; a pawl 241 is arranged on the base frame 1, and the pawl 241 is used to limit the rotation of the ratchet; a fourth gear 250 is rotatably arranged on the base frame 1, and the fourth gear 250 is meshed with the third gear 230 at one end of the conveying roller 220; a fifth gear 260 is rotatably arranged on the base frame 1, and the fifth gear 260 is a toothless gear, and the fifth gear 260 is meshed with another third gear 230 at one end of the conveying roller 220 away from the fourth gear 250.

[0054] In this embodiment, the conveying device 2 is composed of a conveyor belt 210 and a conveyor roller 220. When conveying is required, the conveyor belt 210 will perform cyclic conveying through the rotation of the conveyor roller 220, thereby ensuring the smooth and uniform movement of the cardboard on the conveyor belt 210. The ratchet 240 is arranged on the conveyor roller 220 and is fixed with a third gear 230. When the third gear 230 rotates, due to the existence of the ratchet 240, the ratchet 240 on the conveyor roller 220 will be stuck by the pawl 241 to prevent the conveyor roller from reversing and ensure the conveying direction. When the conveyor roller 220 rotates in the reverse direction, there is no The fourth gear 250 and the fifth gear 260 are respectively meshed with different third gears 230. When the fourth gear 250 drives the conveying roller 220, the conveying roller 220 rotates continuously. When the fifth gear 260 drives the conveying roller 220, the conveying roller 220 operates intermittently. By switching the drive between the two gears, the conveyor belt 210 of the printing press can be switched between the one-pass mode and the scanning mode, thereby ensuring the stability of the cardboard conveyed by the conveyor belt 210 in the two printing modes and improving the printing quality.

[0055] Furthermore, the nozzles 320 are arranged in double rows with staggered positions.

[0056] In this embodiment, the nozzles 320 are of double staggered row design. The double staggered row design enables the original gaps between the nozzles 320 to be filled by the nozzles 320 of another row, ensuring that during one-pass printing, the cardboard can be sprayed more evenly by the nozzles 320, thereby improving the printing quality as much as possible.

[0057] Furthermore, the protective shell 4 is arranged on the base frame 1 and the printing head 3 .

[0058] In this embodiment, since the device as a whole has gears to drive the conveyor belt 210 for transportation, there will be teeth exposed to the outside. These exposed teeth may not only cause paper jams, but also affect the safety of operators. Therefore, a protective shell 4 is designed and installed to ensure that the gears can rotate normally without affecting the cardboard or operators, thereby improving the safety of the printing press.

[0059] Furthermore, it also includes: a guide rod 510 is arranged on the base frame 1, and the guiding direction of the guide rod 510 is the same as the moving direction of the printing head 3; there are a plurality of sliders 520, which are arranged on the printing head 3, and the sliders 520 are slidably arranged on the guide rod 510.

[0060] In this embodiment, the print head 3 is arranged to slide, and the guide rod 510 is used to guide the sliding direction of the print head 3. The surface of the guide rod 510 is relatively smooth, and the slider 520 is slidably arranged on the guide rod 510. The friction force encountered by the slider 520 when sliding on the guide rod 510 is relatively small. Therefore, the guide rod 510 not only plays a guiding role, but also reduces the resistance encountered by the print head 3 when it moves, thereby improving the printing efficiency of the printing press.

[0061] Furthermore, it also includes: a rack 610 is arranged on the base frame 1; a sixth gear 620 is rotatably arranged on the printing head 3, and the sixth gear 620 is engaged with the rack 610; a second driving member 630 is arranged on the printing head 3, and the sixth gear 620 is arranged on the printing head 3 through the second driving member 630, and the second driving member 630 is used to drive the sixth gear 620 to rotate.

[0062] In this embodiment, the second driving member 630 is a motor, and can also be a device such as a small motor that can drive the gear to rotate. The second driving member 630 drives the sixth gear 620 to rotate, so that the printing head 3 can move stably along the direction of the rack 610. At the same time, under the guidance of the guide rod 510, the printing head 3 will not deviate from the preset movement direction, thereby ensuring the printing quality and improving the printing efficiency of the printing machine.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
