Description

Technical Field

[0001] This utility model relates to a printing and coding device. Background Technology

[0002] To prevent counterfeiting, some cat and dog food manufacturers spray QR codes on the inside and outside of their packaging bags to identify the origin of the goods. In the production process of such packaging bags, the packaging material is usually printed first and then transferred to a coding machine for coding. This production method is prone to generating too much waste due to wrinkles and printing errors during repeated unwinding and winding. In addition, because the coding position needs to be precisely positioned, it needs to be positioned multiple times during repeated unwinding and winding, which is a cumbersome process.

[0003] Meanwhile, since not all packaging bags need to be printed with QR codes, a dedicated inkjet printer is only needed when QR codes need to be printed. Therefore, if a dedicated inkjet printer is purchased directly, its efficiency is low, and the corresponding production workshop will also be increased, which greatly increases the production cost. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a printing and coding device that can save procedures and improve the yield rate.

[0005] To achieve this objective, the structure adopted by this utility model is as follows: a printing inkjet equipment, including a printing press and a winding rack, wherein an inkjet support is provided between the end of the printing program on the printing press and the winding rack, and an inkjet printer and a UV light irradiator are provided on the inkjet support.

[0006] The inkjet printer bracket is provided with a first connecting rod and a second connecting rod. The first connecting rod is located above the second connecting rod. One or more inkjet printers are connected to the first connecting rod through a connecting structure, and one or more UV light irradiators are connected to the second connecting rod through a connecting structure. An upper guide roller is provided below the inkjet printer, and a lower guide roller is provided below the upper guide roller. The UV light irradiator is located between the upper guide roller and the lower guide roller.

[0007] The first connecting rod and the second connecting rod are provided with sliding grooves on their surfaces, and the connecting structure is connected to the sliding grooves.

[0008] A speed measuring wheel is connected to one side of the first connecting rod, and the speed measuring wheel is in contact with the upper guide roller.

[0009] A light-shielding plate is provided between the upper guide roller and the lower guide roller. The UV light machine faces the light-shielding plate, which is connected to the inkjet printer bracket.

[0010] The light-shielding plate is inclined, with its bottom close to the printing press and its top away from the printing press. The UV light irradiator is parallel to the light-shielding plate.

[0011] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. After the packaging material is printed by the printing press, it enters the inkjet printer. The inkjet printer on the inkjet printer prints the QR code on the packaging material. The UV light machine dries it quickly. Then it is rolled up, which can realize the QR code printing of the packaging material. This reduces the number of times the packaging material is rolled up and unrolled and positioned, improves production efficiency, and avoids the generation of waste in this process. Attached Figure Description

[0012] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0013] Figure 1 This is the front view of this utility model;

[0014] Figure 2 This is a three-dimensional structural diagram of the inkjet printer and the printer. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1 , Figure 2The printing and coding equipment shown includes a printing press 1 and a winding rack 11. A coding bracket 2 is provided between the end of the printing program on the printing press 1 and the winding rack 11. The coding bracket 2 is equipped with a coding machine 4 and a UV curing machine 7. After the packaging material is printed by the printing press 1, it enters the coding bracket 2. The coding machine 4 on the coding bracket 2 prints QR codes on the packaging material, and the UV curing machine 7 cures it quickly. Then, the material is wound up, which realizes the printing of QR codes on the packaging material. This reduces the number of times the packaging material is wound up and unwound and positioned, improves production efficiency, and avoids the generation of waste in this process. At the same time, by adding a guide roller structure to bypass the coding bracket 2, the printing press 1 can be used to print both packaging materials that need to be printed with QR codes and those that do not, which greatly reduces production costs and equipment space occupation.

[0019] like Figure 2 As shown, the inkjet printer bracket 2 is equipped with a first connecting rod 3 and a second connecting rod 6. The first connecting rod 3 is positioned above the second connecting rod 6. One or more inkjet printers 4 are connected to the first connecting rod 3 via a connecting structure, and one or more UV light-curing machines 7 are connected to the second connecting rod 6 via the connecting structure. The connecting structure includes a connecting block and bolts. The connecting block is connected to the inkjet printer 4 and the UV light-curing machine 7, and then fixed to the first connecting rod 3 or the second connecting rod 6 by bolts, allowing the inkjet printer 4 and the UV light-curing machine 7 to be adjusted in position according to the needs of packaging materials of different sizes. An upper guide roller 5 is provided below the inkjet printer 4, and a lower guide roller 9 is provided below the upper guide roller 5. The UV light-curing machine 7 is positioned between the upper guide roller 5 and the lower guide roller 9. The packaging material passes through the upper guide roller 5 and the lower guide roller 9 in one pass. The inkjet printer 4 performs inkjet printing at the upper guide roller 5, and the material is quickly dried by light-curing between the upper guide roller 5 and the lower guide roller 9.

[0020] The first connecting rod 3 and the second connecting rod 6 are provided with sliding grooves on their surfaces. The connecting structure is connected to the sliding grooves. The connecting block can be configured as a slider that engages with the sliding grooves, or a bolt can be inserted into the sliding grooves, making the connection between the inkjet printer 4 and the UV light machine 7 more stable and the position adjustment more convenient.

[0021] A speed measuring wheel 10 is connected to one side of the first connecting rod 3. The speed measuring wheel 10 is in contact with the upper guide roller 5. The speed of the speed measuring wheel 10 is used to transmit the signal to the control terminal to monitor the feeding speed of the inkjet printing process in real time, so that it matches the printing speed of the printing machine 1.

[0022] A light-shielding plate 8 is provided between the upper guide roller 5 and the lower guide roller 9. The UV light machine 7 faces the light-shielding plate, and the light-shielding plate 8 is connected to the inkjet printer bracket 2. Since long-term exposure to ultraviolet light can cause harm to the human body, the light-shielding plate 8 can block the ultraviolet light from the UV light machine 7 and reduce the spread range of ultraviolet light.

[0023] The light shield 8 is set at an angle, with its bottom close to the printing press 1 and its top away from the printing press 1. The UV light machine 7 is parallel to the light shield 8. Since the printing press 1 is hollow in the center and guide rollers are set to allow packaging materials to pass through, if the UV light machine 7 shines directly on the printing press 1, the area of ​​the light shield 8 would need to be increased to avoid damage to personnel in front of the printing press 1 from ultraviolet light. However, if the ultraviolet light from the inclined light shield 8 leaks out from the top and bottom of the light shield 8, it will only illuminate the obliquely upper part and the bottom of the printing press 1, areas where personnel will not be exposed. Therefore, the area of ​​the light shield 8 can be greatly reduced.

[0024] The inkjet printer bracket 2 is provided with multiple cutouts, which are located between the light shield 8 and the printing machine 1 to facilitate observation of the internal situation.

[0025] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
