[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-Figure 6As shown, the present embodiment provides a humidifying device for a screen printing machine, comprising an annular spray tube 1 and a fog-making mechanism, the annular spray tube 1 being connected to the fog-making mechanism, and a plurality of spray holes 101 being arranged on the inner annular tube surface of the annular spray tube 1, the annular spray tube 1 being used to be arranged on a printing machine table 01, the fog-making mechanism being used to introduce water mist into the annular spray tube 1, so that the annular spray tube 1 sprays and humidifies toward the printing machine table 01 through the spray holes 101, ensuring that the ink maintains an appropriate humidity during the printing process; specifically, the fog-making mechanism in the present embodiment comprises an ultrasonic fog-making machine, and the fog outlet of the ultrasonic fog-making machine is connected to the pipe outlets at both ends of the annular spray tube 1; the present device also comprises a block 2, a water baffle 3 and a lifting mechanism 4, the baffle The block 2 is used to be installed on the printing machine table 01, and the block 2 is a circular structure, and the annular spray tube 1 is arranged around the top of the block 2; the side of the block 2 is penetrated by a bevel groove 201, and the bevel groove 201 is arranged upward from the outside to the inside, and a water storage chamber 301 is arranged on one side of the water baffle plate 3, and is slidably inserted in the bevel groove 201, and the other side is connected to the lifting mechanism 4, and the lifting mechanism 4 can drive the water baffle plate 3 to slide obliquely upward along the bevel groove 201, so that the water storage chamber 301 of the water baffle plate 3 collects water droplets at the spray hole 101 of the annular spray tube 1, effectively avoiding the water droplets at the spray hole 101 from dripping and mixing into the ink of the printing machine, causing the ink dilution to change and affecting the printing effect, thereby improving the practicality of the humidification device.

[0029] In this embodiment, if Figure 5 As shown, a pipe groove 202 is provided on the top inner ring edge of the block 2, the annular spray pipe 1 is fixedly embedded in the pipe groove 202, and all the spray holes 101 are evenly arranged on the inner ring pipe surface of the annular spray pipe 1 along the top inner ring edge of the block 2; four inclined grooves 201 are provided, and the four inclined grooves 201 are respectively located on the four side walls of the block 2, and four water retaining plates 3 are provided, and the water retaining plates 3 are arranged one by one with the inclined grooves 201.

[0030] It should be noted that the size of the water baffle 3 should ensure that each water baffle 3 can cover the spray hole 101 on the corresponding bent edge of the annular spray pipe 1, so as to fully receive the water droplets remaining after the annular spray pipe 1 completes the spray humidification work.

[0031] In this embodiment, the lifting mechanism 4 includes a lifting ring 401 and a driving unit. The lifting ring 401 is movably mounted on the stopper 2, and the driving unit can drive the lifting ring 401 to move up and down; Figure 6 As shown, eight slide rails 402 are horizontally arranged on the outer frame of the lifting ring 401, that is, two slide rails 402 are arranged on each side of the lifting ring 401, and the two slide rails 402 are perpendicular to the corresponding side. Each water baffle 3 is slidably connected to the two slide rails 402 through a connecting portion 302, thereby increasing the stability of the connection between the water baffle 3 and the lifting ring 401.

[0032] Furthermore, if Figure 4 As shown, a waist groove hole 4021 is provided on one side of each slide rail 402, and a limiting groove 4022 is provided on the inner wall of the other side; the connecting portion 302 includes two groups of sliders 3021 and connecting bolts 3022, that is, each water baffle 3 is slidably connected with the two slide rails 402 on the corresponding sides of the lifting ring 401 through the two groups of sliders 3021 and connecting bolts 3022, wherein the sliders 3021 in each group are arranged on the side of the corresponding water baffle 3 away from the inclined groove 201, and are slidably embedded in the corresponding slide rail 402; the threaded end of the connecting bolt 3022 in each group passes through the waist groove The hole 4021 is threadedly connected to the slider 3021, and penetrates the slider 3021 and is slidably connected to the limit groove 4022. When the lifting ring 401 moves upward, the slider 3021 is driven to slide in the slide rail 402 through the connecting bolt 3022, so that the water baffle plate 3 connected to the slider 3021 can move upward along the inclined groove 201, thereby blocking the spray hole 101 of the annular spray pipe 1. The provision of the connecting bolt 3022 also makes it easier to disassemble the water baffle plate 3, which is convenient for daily maintenance and dumping of water collected in the water storage chamber 301 of the water baffle plate 3, thereby improving the practicality of the device.

[0033] In this embodiment, the driving part includes at least two electric telescopic rods 403, and the two electric telescopic rods 403 are respectively supported at the bottom of a group of opposite side edges of the lifting ring 401; specifically, a support plate 404 is respectively arranged in the middle of a group of opposite side edges of the lifting ring 401, and the two support plates 404 are symmetrically arranged. The two electric telescopic rods 403 are respectively supported at the bottom of the two support plates 404, so as to synchronously drive the lifting ring 401 to rise and fall.

[0034] In this embodiment, a water absorption strip 303 is bonded to one side of the water storage chamber 301 of the water baffle plate 3 close to the annular spray tube 1 through Velcro. When the water baffle plate 3 moves obliquely upward, the water absorption strip 303 first contacts the spray hole 101 of the annular spray tube 1, and the water droplets at the spray hole 101 are absorbed by the water absorption strip 303. At the same time, the water absorption strip 303 can also clean the spray hole 101 to prevent dirt from gathering at the spray hole 101 and affecting normal spraying. In addition, the water absorption strip 303 is bonded to the water baffle plate 3 with Velcro for easy replacement.

[0035] The working process of the humidifying device for a screen printing machine provided in this embodiment is as follows:

[0036] When in use, the block 2 is installed together with the annular spray tube 1 on the printing machine table 01, and the ultrasonic fog machine is started to pass water mist into the annular spray tube 1, and the printing machine table 01 is sprayed and humidified through the spray hole 101 of the annular spray tube 1 to ensure that the ink in the printing process maintains appropriate humidity; after the humidification is completed, the two electric telescopic rods 403 are started to drive the lifting ring 401 to move upward, and then the four water retaining plates 3 are driven at the same time through the eight slide rails 402 to slide obliquely upward along the four inclined grooves 201 on the side of the block 2 until the four water retaining plates 3 fully cover the ink. All the spray holes 101 of the annular spray tube 1 are blocked. During this process, first, the water droplets at the spray hole 101 are absorbed and cleaned by the water absorption strip 303 on the water baffle plate 3, and at the same time, the spray hole 101 is cleaned. Then, after the water baffle plate 3 reaches a certain height, the opening of the water storage cavity 301 of the water baffle plate 3 faces the spray hole 101, and can collect the water droplets that continue to drip from the spray hole 101, effectively avoiding the water droplets at the spray hole 101 from dripping and mixing into the ink of the printing press, causing the ink dilution to change and affecting the printing effect, thereby improving the practicability of the humidifying device.
