Description

Technical Field

[0001] The utility model relates to printing equipment. Background Art

[0002] Different printing equipment has different printing structures. During the printing process, the substrate is continuously non-retracted or intermittently retracted. Different types of printing equipment are selected according to different printing requirements to perform corresponding printing operations on the substrate. At present, a printing equipment can only perform a single mode of printing operation. A single continuous non-retracting printing equipment has a high printing speed, but it needs to be equipped with a large number of printing plate rollers according to the length of the printing pattern, which will result in higher printing costs and longer printing cycles; a single intermittent retracting printing equipment has a low printing speed and low efficiency. If a printing plant configures multiple different types of printing equipment to meet the needs of more modes of printing production, the cost of use will increase and the requirements for the use site will be higher, which is obviously unreasonable. In addition, the printing equipment also needs to set the main traction structure at the front and rear of the head and tail of the whole machine to cooperate with the traction of the substrate, which will cause the entire printing equipment to be too long, restricting some factory sites and making it unsuitable. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a printing device containing color group curing that can meet both continuous printing and intermittent printing.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a printing device containing color group curing includes a printing group, the printing group includes at least two group units, the group units are arranged front to back with each other, the front side of the printing group is the input side of the substrate, the rear side of the printing group is the output side of the substrate, and each group unit includes a working module, which is characterized in that: the working module includes a printing mechanism, a unit curing mechanism and a unit floating mechanism; the printing mechanism includes a plate roller, a transfer roller and a printing bottom roller, the unit floating mechanism includes a unit floating seat, a unit front floating roller and a unit rear floating roller are arranged on the unit floating seat, and the unit floating seat is connected to the unit floating drive motor in a transmission manner; each group unit also includes a unit front traction device and a unit rear traction device, and the working module is arranged between the unit front traction device and the unit rear traction device.

[0005] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0007] In addition, the unit front traction device and the unit rear traction device maintain a synchronous linear speed to pull the printing material.

[0008] For example, it has a color separation and curing intermittent group retreat printing mode, in which each unit front traction device has a substrate input end and a substrate output end, and each unit rear traction device has a substrate input end and a substrate output end; in each unit group, the substrate output end of the unit front traction device is connected with the substrate input end of the unit front floating roller, the substrate output end of the unit front floating roller is connected with the substrate input end of the printing mechanism, the substrate output end of the printing mechanism is connected with the substrate input end of the unit curing mechanism, the substrate output end of the unit curing mechanism is connected with the substrate input end of the unit rear floating roller, and the substrate output end of the unit rear floating roller is connected with the substrate input end of the unit rear traction device; between the unit group unit and another unit group unit at the rear side, the substrate output end of the unit rear traction device of the unit group unit is connected with the substrate input end of the unit front traction device of another unit group unit at the rear side. After further optimization, the unit front traction device and the unit rear traction device of the unit are respectively in the material receiving operation state, the unit curing mechanism is in the material receiving operation state, and the unit floating mechanism is in the connecting floating operation state.

Further optimization, the unit front traction device and the unit rear traction device of the unit unit are respectively in the material receiving operation state, the unit curing mechanism is in the material receiving operation state, and the unit floating mechanism is in the material receiving non-floating operation state or in the material avoiding state.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0022] Referring to the accompanying drawings, the printing device with color group curing in this embodiment includes a printing unit 2, the printing unit 2 includes at least two unit units 20, and multiple units can be provided according to needs. The unit units 20 are arranged front to back with each other, the front side of the printing unit 2 is the substrate input side, and the rear side of the printing unit 2 is the substrate output side, which can be used for printing on a roll substrate. The printing mechanism 22 can be used to print the substrate. Each unit unit 20 includes a working module 21, and the working module (21) includes a printing mechanism (22), a unit curing mechanism (23) and a unit floating mechanism (24); The brush mechanism (22) includes a plate roller (221), a transfer roller (222) and a printing bottom roller (223). The unit floating mechanism (24) includes a unit floating seat (241). The unit floating seat (241) is provided with a unit front floating roller (242) and a unit rear floating roller (243). The unit floating seat (241) is connected to a unit floating drive motor in a transmission manner. The unit front floating roller 242 and the unit rear floating roller 243 will float along with the unit floating seat 241. The unit floating drive motor cooperates to drive the unit floating seat 241 to perform floating operation, such as the floating operation of left and right movements in the figure. Each unit (20) also includes a unit front traction device (25) and a unit rear traction device (26). The working module (21) is arranged between the unit front traction device (25) and the unit rear traction device (26). The front traction device 25 and the rear traction device 26 can be used for winding the printing substrate. When the printing substrate is input and output from each unit 20, the front traction device 25 and the rear traction device 26 can cooperate to pull the printing substrate in and out, which can ensure the stability of the printing substrate tension in each unit 20 and ensure the printing quality.

[0023] In the printing equipment with color group curing, each printing unit has its own unit curing mechanism to fix the printed substrate to achieve color group curing. Its structure is relatively simple, and there is no need to configure the main traction structure of the substrate on the front and back sides of the printing unit. The substrate can be wound in different paths according to different needs, which can meet both continuous printing and intermittent printing. There is a common structure in continuous printing and intermittent printing, which makes the printing equipment relatively compact, and one device can meet different printing needs and adapt to different printing process needs. The cost of use is relatively low; there is no need to purchase multiple printing equipment, and the site requirements are relatively low; for new specifications of small and medium-sized single prints, there is no need to configure new rollers, and the existing specifications of rollers are used for intermittent return printing, with a short delivery cycle and high efficiency. When in use, the substrate can be wound and arranged according to the printing mode of different needs, so as to achieve the effect of one machine for multiple uses.

[0024] The following optimization or further explanation may be performed based on the above embodiments.

[0025] For example, the printing device is a color group curing printing device without a substrate main traction structure, and the front and rear sides of the printing unit do not have a substrate main traction structure, so the entire device is relatively shorter and more compact. The unit front traction device (25) and the unit rear traction device (26) maintain a synchronous linear speed to pull the substrate.

[0026] For example, in the first embodiment, the printing device has a color separation and curing intermittent group retreat printing mode. In this mode, after the substrates are printed in different unit units 20, they are directly cured by the unit curing mechanism 23 in the corresponding unit unit 20 to achieve group curing, and the substrates are intermittently grouped and retreated during the entire normal printing process, which can eliminate the blank gaps on the substrates. The intermittent group retreat will be controlled by the unit front floating roller 242 and the unit rear floating roller 243 of each unit unit 20 along with the unit floating seat 241 through floating coordination grouping. Each unit front traction device (25) has a substrate input end and a substrate output end, and each unit rear traction device (26) has a substrate input end and a substrate output end; in each unit unit (20), the substrate output end of the unit front traction device (25) is connected to the substrate input end of the unit front floating roller (242), the substrate output end of the unit front floating roller (242) is connected to the substrate input end of the printing mechanism (22), the substrate output end of the printing mechanism (22) is connected to the substrate input end of the unit curing mechanism (23), the substrate output end of the unit curing mechanism (23) is connected to the substrate input end of the unit rear floating roller (243), and the substrate output end of the unit rear floating roller (243) is connected to the substrate input end of the unit rear traction device (26); in each unit unit (2 0) and another unit unit (20) at the rear side, the substrate output end of the unit rear traction device (26) of the unit unit (20) is connected with the substrate input end of the unit front traction device (25) of another unit unit (20) at the rear side, so as to realize the substrate output and input connection winding layout; the unit front traction device 25 and the unit rear traction device 26 can cooperate to pull the substrate into and out, so as to ensure the stability of the substrate tension in each unit unit 20, so as to connect the substrate in the corresponding unit unit 20 for coordinated traction and feeding, and avoid the tension change fluctuation affecting the printing quality during the intermittent group retreat operation coordination process of each unit unit 20 (controlled by the unit front traction device 25 and the unit rear traction device 26 through floating coordination grouping), thereby ensuring the printing stability and the printing quality. The unit front traction device (25) and the unit rear traction device (26) of the unit unit (20) are respectively in a material receiving operation state, and the unit curing mechanism (23) is in a material receiving operation state, so as to connect the printing substrates in the corresponding unit unit 20 and perform group curing treatment on them; the unit floating mechanism (24) is in a connecting and floating operation state, so as to connect the printing substrates in the corresponding unit unit 20 to float, cooperate with the printing substrates in the corresponding unit unit 20 to be retracted, and float back to the original position after the retraction is completed.

[0027] Or, for example, in the second embodiment, the printing device has a color separation curing continuous non-retracting printing mode, in which, after the substrate is printed in different unit units 20, it is directly cured by the unit curing mechanism 23 in the corresponding unit unit 20 to achieve group curing, and the substrate does not retract during the entire normal printing process; each unit front traction device (25) has a substrate input end and a substrate output end, and each unit rear traction device (26) has a substrate input end and a substrate output end, and the unit front traction device (25) and the unit rear traction device (26) cooperate to pull the substrate forward; in each unit unit (20), the unit front traction device (25) and the unit rear traction device (26) The substrate output end of the traction device (25) is connected to the substrate input end of the printing mechanism (22), the substrate output end of the printing mechanism (22) is connected to the substrate input end of the unit curing mechanism (23), and the substrate output end of the unit curing mechanism (23) is connected to the substrate input end of the unit rear traction device (26); between the unit unit (20) and another unit unit (20) at the rear side, the substrate output end of the unit rear traction device (26) of the unit unit (20) is connected to the substrate input end of the unit front traction device (25) of another unit unit (20) at the rear side; and the substrate output and input connection winding layout is realized. The unit front traction device (25) and the unit rear traction device (26) of the unit unit (20) are respectively in a material receiving operation state so as to pull the substrate. The unit curing mechanism (23) is in a material receiving operation state so as to complete the curing of the substrate after printing in the unit unit 20. The unit floating mechanism 24 is in a material receiving non-floating operation state (ie, the printing material passes through the unit floating mechanism 24 without corresponding floating operation) or in a material receiving avoidance state (ie, the printing material does not pass through the unit floating mechanism 24).

[0028] In addition to the above embodiments, it is further explained that the unit front traction device (25) includes a front unit traction roller (251); the unit rear traction device (26) includes a rear unit traction roller (261); the front unit traction roller (251) and the rear unit traction roller (261) are also respectively connected to traction motors; the corresponding traction motors (such as servo motors) cooperate to drive the corresponding traction rollers to operate for actively traction of the printing substrate; the front unit traction roller (251) and the rear unit traction roller (261) are also respectively equipped with traction auxiliary pressure rollers; the unit floating mechanism (24) also includes a unit front fixed roller and a unit rear fixed roller. The fixed roller, the front fixed roller of the unit and the front floating roller (242) of the unit are matched correspondingly, and the rear fixed roller of the unit and the rear floating roller (243) of the unit are matched correspondingly, and the floating substrate is matched to store the substrate or to pull the substrate forward and backward or control the tension of the substrate through the floating substrate. The unit curing mechanism (23) includes a curing component (231), and the curing component (231) is equipped with a feeding roller (232). The curing component (231) is arranged beside the feeding roller (232); the feeding roller (232) also has a cooling structure (such as a water cooling channel or an air cooling channel, etc.) to avoid excessive temperature during curing.
