Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to printing equipment with a multi-mode switching structure capable of switching to printing in different modes. Background Art

[0002] Different printing equipment has different modes of printing structure. During the printing process, the substrate is continuously non-retracted or intermittently retracted. Different types of printing equipment are selected according to different printing needs 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.

[0036] 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.

[0037] Referring to the drawings, the printing device with a multi-mode switching structure in the embodiment of the present embodiment includes a front mechanism 1, a printing unit 2 and a rear mechanism 3, which can provide multiple modes for selecting replacement printing for roll-type substrates.

The group units 20 are arranged front to back with each other, and the printing group 2 is arranged between the front mechanism 1 and the rear mechanism 3, that is, multiple group units 20 are arranged between the front mechanism 1 and the rear mechanism 3.

[0039] The leading mechanism 1 includes a leading traction device 10 and a leading floating device 11 .

[0040] The front traction device 10 can be used to cooperate with traction of the printing substrate.

[0041] The front floating device 11 can be used to cooperate with the floating substrate, and the front floating device 11 includes a front floating roller 110, and the front floating roller 110 can cooperate with the substrate through floating operation. The front floating roller 110 is connected to the front floating drive motor, and the front floating drive motor cooperates to drive the front floating roller 110 to float, such as the floating operation of the left and right movements in the figure.

[0042] The front traction device 10 is arranged before the front floating device 11 , that is, when the printing substrate is wound, it can first pass through the front traction device 10 and then pass through the front floating device 11 to lay the printing substrate.

[0043] The rearward mechanism 3 includes a rearward traction device 30 and a rearward floating device 31 .

[0044] The rear traction device 30 can be used to cooperate with traction of the printing substrate.

[0045] The rear traction device 30 is also connected to the centralized curing mechanism 4, and the centralized curing mechanism 4 can cooperate to perform corresponding curing on the printed substrate according to needs.

[0046] The rear floating device 31 can be used to cooperate with the floating substrate, and the rear floating device 31 includes a rear floating roller 311, which can cooperate with the substrate through floating operation. The rear floating roller 311 is connected to the rear floating drive motor, and the rear floating drive motor cooperates to drive the rear floating roller 311 to float, such as the floating operation of the left and right movements in the figure.

[0047] The rear traction device 30 is arranged behind the rear floating device 31 , that is, when the printing material is wound, it can first pass through the rear floating device 31 and then pass through the rear traction device 30 to lay the printing material.

[0048] Among them, each 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 printing mechanism 22 can be used to print on the substrate, and the printing mechanism 22 includes a plate roller 221, a transfer roller 222 and a printing bottom roller 223, wherein the transfer roller 222 and the printing bottom roller 223 are used for input and output of the substrate, which is relatively mature; according to needs, the unit curing mechanism 23 can cooperate to perform corresponding curing on the printed substrate.

The front traction device 25 and the rear traction device 26 can be used for winding the substrate, and when the 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 substrate into and out according to demand.

[0051] In the printing device with the multi-mode switching structure, various matching structures have been reserved in its structure. The printing material (i.e., the printing material, which is a roll material) can be routed and wound along different paths according to different needs, and different printing mode switching options can be provided. In addition, different modes have a common structure, which makes the printing device with the multi-mode switching structure relatively compact, and one device can meet the printing needs of different modes. The cost of use is relatively low, there is no need to purchase multiple printing devices, and the site requirements are also relatively low.

[0052] The following optimization or further explanation may be performed based on the above embodiments.

[0053] The printing device of the multi-mode switching structure has at least mode 1, mode 2, mode 3 and mode 4. Multiple printing working modes are used for selection and arrangement, wherein mode 1 is a centralized curing non-retracting continuous printing mode, mode 2 is a group curing non-retracting continuous printing mode, mode 3 is a group curing intermittent overall retracting printing mode, and mode 4 is a group curing intermittent group retracting printing mode. The corresponding mode can be switched and selected according to different printing requirements. When in use, the substrate can be arranged according to the mode of different requirements. In mode 1 and mode 2, a rubber blanket connected end to end (with almost no gap between the end) can be arranged on the transfer roller 222; in mode 3 and mode 4, a rubber blanket with a spacing between the end and the end can be arranged on the transfer roller 222 to form an avoidance space when intermittently returning.

[0054] For example, in mode 1, the rear traction device 30 is also connected to the centralized curing mechanism 4, and the substrate is centrally cured at the centralized curing mechanism 4 after printing in different unit units 20, and the substrate does not retreat during the entire normal printing process, wherein:

[0055] The substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 (of the unit 20) in the printing unit 2, so that the substrate output and input are connected and arranged around the layout;

[0056] Between the unit unit 20 and another unit unit 20 at the rear side, the substrate output end of the printing mechanism 22 of the unit unit 20 is connected with the substrate input end of the printing mechanism 22 of another unit unit 20 at the rear side, so that the substrate output and input are connected and arranged around; the substrate can be pulled straight through between the two printing mechanisms 22, such as directly passing the substrate horizontally;

[0057] The substrate output end of the rear printing mechanism 22 (of the unit 20) in the printing unit 2 is connected to the substrate input end of the rear traction device 30, so that the substrate output and input are connected and arranged in a winding manner;

[0058] The rear traction device 30 is also connected to the centralized curing mechanism 4, and the centralized curing mechanism 4 can cooperate with the printed substrate to perform corresponding curing. The centralized curing mechanism 4 is in an online state, and the substrate can pass through the centralized curing mechanism 4, so that the centralized curing mechanism 4 can perform centralized curing on the substrate. In mode 1, the centralized curing mechanism 4 is in an online state; in other modes (such as modes 2, 3, and 4; described below), the rear traction device 30 is also connected to the centralized curing mechanism 4, and the centralized curing mechanism 4 is in an online state or a non-curing operation state or an online state (it can even be used for secondary curing). Of course, the centralized curing mechanism 4 may not be provided.

[0059] In addition, mode 1 can also optimize:

[0060] The front floating device 11 is in a material receiving non-floating operation state (i.e. the printing material passes through the front floating device 11 without corresponding floating operation) or in a material avoiding state (i.e. the printing material does not pass through the front floating device 11). The material receiving non-floating operation state means that the printing material can pass through the front floating device 11 without floating operation during the printing process (the same applies to the following and will not be described in detail).

[0061] The rear floating device 31 is in a material receiving non-floating operation state (i.e. the printing material passes through the rear floating device 31 but does not need to perform corresponding floating operation) or in a material receiving avoidance state (i.e. the printing material does not pass through the front floating device 11);

[0062] The unit front traction device 25 of the front unit 20 in the printing unit 2 is in a state of avoiding material connection (i.e., the substrate is not wound through the unit front traction device 25), or the unit front traction device 25 is in a state of receiving material connection (i.e., the substrate is laid through the unit front traction device 25) and the unit front traction device 25 and the front traction device 10 keep traction of the substrate at a synchronous linear speed; the unit front traction devices 25 of other unit units 20 are in a state of avoiding material connection (i.e., the substrate is not wound through them);

[0063] The rear traction device 30 and the front traction device 10 maintain a synchronous linear speed to pull the printing material;

[0064] The unit curing mechanism 23 and the unit post-traction device 26 are in a state of avoiding the material connection (i.e., the substrate does not pass through them), and the substrate does not need to be unit cured and post-unit traction;

[0065] The unit floating mechanism 24 (such as its unit front floating roller 242) of the front unit unit 20 in the printing unit 2 is in a non-floating operation state for material connection (i.e., the printing material is laid out through the unit floating mechanism 24, but no corresponding floating operation is required) or in a state of avoiding material connection, and other unit floating mechanisms 24 are in a state of avoiding material connection (i.e., the printing material is not passed around and through these unit floating mechanisms 24).

[0066] For example, in mode 2, 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 not returned during the entire normal printing process, wherein:

[0067] The substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 (of the unit 20) in the printing unit 2, so that the substrate output and input are connected and arranged around the layout;

[0068] In each unit 20, the substrate output end of the printing mechanism 22 is connected to the substrate input end of the unit curing mechanism 23, so that the substrate output and input are connected and arranged around the layout;

[0069] Between the unit unit 20 and another unit unit 20 at the rear side, the substrate output end of the unit curing mechanism 23 of the unit unit 20 is connected with the substrate input end of the printing mechanism 22 of another unit unit 20 at the rear side, so that the substrate output and input are connected and arranged in a winding manner;

[0070] The substrate output end of the unit curing mechanism 23 of the rear unit unit 20 in the printing unit 2 is connected to the substrate input end of the rear traction device 30, so that the substrate output and input are connected and arranged in a winding manner.

[0071] In addition, mode 2 can also be optimized:

[0072] The front floating device 11 is in a material receiving non-floating operation state (i.e. the printing material passes through the front floating device 11 without corresponding floating operation) or in a material avoiding state (i.e. the printing material does not pass through the front floating device 11);

[0073] The rear floating device 31 is in a material receiving non-floating operation state (i.e. the printing material passes through the rear floating device 31 but does not need to perform corresponding floating operation) or in a material receiving avoidance state (i.e. the printing material does not pass through the front floating device 11);

[0074] The unit front traction device 25 and / or the unit rear traction device 26 of the unit unit 20 are in a state of avoiding the material connection (i.e., the substrate is not wound through them), or the unit front traction device 25 and / or the unit rear traction device 26 are in a state of connecting the material (i.e., the substrate is not wound through them) and the unit front traction device 25 and / or the unit rear traction device 26 pull the substrate at a synchronous linear speed with the front traction device 10;

[0075] The rear traction device 30 and the front traction device 10 maintain a synchronous linear speed to pull the printing material;

[0076] The unit curing mechanism 23 is in a material receiving operation state so as to connect the substrates in the corresponding unit unit 20 and perform group curing treatment on them;

[0077] 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).

[0078] For another example, in mode 3, 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 is intermittently retreated as a whole during the entire normal printing process, which can eliminate the blank gap on the substrate. The intermittent overall retreat will be controlled by the front floating device 11 and the rear floating device 31 through floating coordination, wherein:

[0079] The substrate output end of the front traction device 10 is connected with the substrate input end of the front floating device 11, so that the substrate output and input are connected and arranged in a winding manner;

[0080] The substrate output end of the front floating device 11 is connected to the substrate input end of the unit front floating roller 242 of the unit floating mechanism 24 of the front unit unit 20 in the printing unit 2, so that the substrate output and input are connected and arranged in a winding manner;

[0081] In each unit 20, 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, and the substrate output end of the unit curing mechanism 23 is connected to the substrate input end of the unit rear floating roller 243 of the unit floating mechanism 24, so that the substrate output and input are connected and arranged in a winding manner;

[0082] Between the unit unit 20 and another unit unit 20 at the rear side, the substrate output end of the unit rear floating roller 243 of the unit floating mechanism 24 of the unit unit 20 is connected with the substrate input end of the unit front floating roller 242 of the unit floating mechanism 24 of another unit unit 20 at the rear side, so that each unit unit 20 realizes the substrate output and input connection winding layout;

[0083] The substrate output end of the unit rear floating roller 243 of the unit floating mechanism 24 of the rear unit unit 20 in the printing unit 2 is connected to the substrate input end of the rear floating device 31, so that the substrate output and input are connected and arranged in a winding manner;

[0084] The printing material output end of the rear floating device 31 is connected with the printing material input end of the rear traction device 30 so that the printing material output and input are connected and arranged in a winding manner.

[0085] In addition, mode three can also be optimized:

[0086] The front floating device 11 is in a connected floating operation state, and the rear floating device 31 is in a connected floating operation state, so as to coordinate and control the intermittent retreat of the entire printing material (and its return to its original position after retreat) through floating operation;

[0087] The unit front traction device 25 and / or the unit rear traction device 26 of the unit unit 20 are in a state of avoiding the material connection (i.e., the substrate is not wound through them), or the unit front traction device 25 and / or the unit rear traction device 26 are in a state of connecting the material (i.e., the substrate is not wound through them) and pull the substrate at a synchronous linear speed with the front traction device 10;

[0088] The rear traction device 30 and the front traction device 10 maintain a synchronous linear speed to pull the printing material;
