Description

Technical Field

[0001] This utility model belongs to the field of cup printing technology, and in particular relates to ink protection mechanism and printing device. Background Technology

[0002] In existing printing ink stations, to prevent the ink in the ink fountain from solidifying and thus failing to be transferred to the printing plate, ultimately affecting the printing quality, an open design is usually used above the ink fountain. This allows for easy manual addition or stirring of the ink, preventing ink from solidifying.

[0003] However, with this open structure, the ink is exposed to the outside, making it easy for dust and foreign objects to enter the ink, resulting in poor ink quality and thus making the ink unusable. Secondly, the ink solidifies quickly, requiring frequent manual stirring, which increases labor costs. Ink that has not been stirred for a long time will also solidify, affecting the printing quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ink protection mechanism and printing device that can isolate external dust and facilitate observation of the internal ink status.

[0005] To achieve the above objectives, this utility model employs the following technical solution: an ink protection mechanism, comprising a base plate, side ink blocks on both sides of the base plate, a front ink block on one side of the top of the base plate, an ink fountain roller in contact with one side of each side ink block, the bottom of the ink fountain roller being in contact with the base plate, the base plate, side ink blocks, front ink block, and ink fountain roller together forming an ink receiving area, a stop block connected to one side of each side ink block, a dustproof plate detachably connected to the top of each stop block, and an ink stirring assembly for stirring the ink being disposed above the ink fountain roller.

[0006] Optionally, the ink stirring assembly includes an ink stirring cylinder, with a mounting block fixedly connected to the output end of the ink stirring cylinder, and an ink stirring rod connected to one side of the mounting block, the end of which extends to the ink receiving area.

[0007] Optionally, a support plate is provided at the bottom of the base plate, and two blocks are fixedly connected to the top of each side of the support plate. A connecting plate is provided on both sides of the support plate, and one end of the connecting plate is rotatably connected to the ink fountain roller.

[0008] Optionally, the dustproof plate has folded edges on all four sides, two of which have connecting holes. The side of the block has mounting holes corresponding to the connecting holes, and the block and the dustproof plate are fixed together by bolts.

[0009] Optionally, the stop block is made of magnetic material, and a magnet is attached to the bottom of the dustproof plate, with the position of the magnet corresponding to the position of the stop block.

[0010] Optionally, a handle is installed on the top of the dustproof panel.

[0011] Optionally, the dustproof plate is made of a transparent material to allow observation of the ink's condition from the outside.

[0012] A printing apparatus includes at least two parallel fixed plates, with the two ends of the ink fountain roller rotatably connected to the two fixed plates respectively.

[0013] Optionally, the ink-stirring cylinder is fixedly connected to the inner wall of the fixed plate, and the sides of both connecting plates are fixedly connected to the inner wall of the fixed plate via connecting rods.

[0014] Optionally, a roller assembly is provided between the two fixed plates, and a transmission assembly is provided on the outer side of one of the fixed plates.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. By attaching magnets to the bottom of the dustproof plate, the dustproof plate is fixed to the block by adsorption. The dustproof plate is made of transparent material, which makes it easy to observe the ink status from the outside at all times and to stir the ink in time to prevent solidification. The process of removing and installing the dustproof plate is simple. When it is necessary to stir the ink inside, simply lift the dustproof plate to remove it. It is convenient, quick and efficient.

[0016] 2. By setting up an ink stirring assembly, the ink stirring cylinder repeatedly extends and retracts, driving the ink stirring rod to move back and forth in the ink, thereby achieving automatic ink stirring and significantly reducing the frequency of manual ink stirring; the dustproof plate is equipped with folded edges on all four sides, effectively preventing dust and other impurities from entering the ink, thus improving the ink printing quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1 Reference Figures 1-5This embodiment provides an ink protection mechanism, specifically including a base plate 1. Side ink blocks 2 are provided on both sides of the base plate 1, and a front ink block 3 is provided on one side of the top of the base plate 1. An ink fountain roller 4 is provided in contact with one side of the side ink blocks 2. The bottom of the ink fountain roller 4 is in contact with the base plate 1. The base plate 1, the side ink blocks 2, the front ink blocks 3 and the ink fountain roller 4 together form an ink receiving area. A baffle 5 is connected to one side of each side ink block 2. A dustproof plate 6 is detachably connected to the top of the baffle 5. An ink stirring assembly for stirring the ink is provided above the ink fountain roller 4.

[0023] The side ink block 2 is made of copper, and the part in contact with the ink fountain roller 4 is arc-shaped. The top of the side ink block 2 is sloping. The dustproof plate 6 is made of transparent PV material. When the dustproof plate 6 is installed on top of the side ink block 2, it is in an inclined state, which allows workers to observe the internal ink condition in real time, stir the ink in time, and avoid ink solidification that would lead to poor printing. At the same time, the dustproof plate 6 can prevent dust from entering the ink. The ink receiving area has an open structure. When adding ink, the ink is poured directly onto the base plate 1. The ink will not leak out due to the obstruction of the front ink block 3, the ink fountain roller 4, and the two side ink blocks 2.

[0024] Example 2 This embodiment provides an ink protection mechanism, which differs from the first embodiment in that the ink stirring assembly includes an ink stirring cylinder 701, an installation block 702 is fixedly connected to the output end of the ink stirring cylinder 701, an ink stirring rod 703 is connected to one side of the installation block 702, and the end of the ink stirring rod 703 extends to the ink receiving area.

[0025] A support plate 8 is provided at the bottom of the base plate 1. The top of the two sides of the support plate 8 is fixedly connected to two blocks 5 respectively. A connecting plate 9 is provided on both sides of the support plate 8. One end of the connecting plate 9 is rotatably connected to the ink fountain roller 4.

[0026] The dustproof plate 6 has folded edges 601 on all four sides, two of which have connecting holes 602. The side of the block 5 has mounting holes corresponding to the connecting holes 602. The block 5 and the dustproof plate 6 are fixed by bolts.

[0027] The stop block 5 is made of magnetic material, and a magnet 603 is attached to the bottom of the dustproof plate 6, with the position of the magnet 603 corresponding to that of the stop block 5. A handle 604 is installed on the top of the dustproof plate 6. The dustproof plate 6 is made of transparent material to allow observation of the ink condition from the outside.

[0028] The ink stirring cylinder 701 is fixed to the printing apparatus, and the connecting plate 9 is connected to both sides of the printing apparatus to secure the entire ink protection mechanism. The ink stirring cylinder 701 is located diagonally above the ink receiving area. The ink stirring rod 703 extends into the ink receiving area through multiple bends. The end of the ink stirring rod 703 located in the ink receiving area has a bent head to increase the contact area with the ink and improve stirring efficiency. The ink stirring assembly can automatically stir the ink, preventing ink solidification and resulting in printing defects.

[0029] After the printing station is cleaned and ink is added, the dustproof plate 6 is installed above the ink receiving area. There are two installation methods: one is to use a magnet 603 to attach the dustproof plate 6 to the top of the block 5, and the other is to use bolts to fix the corresponding folded edge 601 of the dustproof plate 6 to the block 5.

[0030] During normal use, the installation is secured using magnet 603. Adhesive is applied to the back of magnet 603, which is then firmly attached to dust cover 6. After pouring ink into the ink-containing area, magnet 603 at the bottom of dust cover 6 is aligned with the two left and right stops 5 to attract the ink. The folded edges 601 around dust cover 6 effectively prevent dust from entering the ink through gaps. This installation method allows dust cover 6 to be removed and installed at any time, facilitating the addition and stirring of ink.

[0031] When the printing device is not used for a long time, bolts are used to pass through the connecting holes 602 on the folded edge 601 and the mounting holes on the side of the stop block 5 in sequence to achieve fixation. This installation method can fix the dustproof plate 6 more firmly and prevent the dustproof plate 6 from falling off due to accident.

[0032] Example 3 Reference Figure 1 and Figure 2 This embodiment provides a printing apparatus, including at least two parallel fixed plates 10, with the two ends of an ink fountain roller 4 rotatably connected to the two fixed plates 10 respectively. An ink stirring cylinder 701 is fixedly connected to the inner wall of the fixed plate 10, and the sides of two connecting plates 9 are fixedly connected to the inner wall of the fixed plate 10 via connecting rods. A roller assembly 11 is disposed between the two fixed plates 10, and a transmission assembly 12 is disposed on the outer side of one of the fixed plates 10.

[0033] The ink fountain roller 4 transfers ink to the roller assembly 11. A power mechanism is connected to one side of the transmission assembly 12, which transmits power to the roller assembly 11, causing the roller to rotate and complete the printing process. This printing device effectively and safely protects the ink in the ink reservoir, preventing foreign objects and dust from entering. It features a simple structure, easy assembly and disassembly, real-time ink agitation, and real-time monitoring of the ink level in the ink fountain. Adding ink is also convenient. In practical applications, after prolonged use, the ink showed virtually no foreign objects or dust, improving print quality and saving significant time spent manually agitating the ink. The test results were excellent.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
