[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please refer to Figures 1 to 5 Example 1: This utility model proposes a printing wastewater discharge device, including: a pool body assembly 1 and a treatment assembly; the pool body assembly 1 includes a discharge pool 101 and an electric push rod 102, the electric push rod 102 is fixedly installed on the top of the discharge pool 101, and the treatment assembly consists of a capture mechanism 2 and a scraping mechanism 3. The capture mechanism 2 includes a reciprocating seat 201, a drive roller 202, a support roller 203, and a capture steel belt 204. The reciprocating seat 201 is inserted into the top of the discharge pool 101, and one end of the push rod of the electric push rod 102 is fixedly installed on the side of the reciprocating seat 201. The drive roller 202 and the support roller 203 are rotatably connected to the top and bottom of the reciprocating seat 201, respectively. The capture steel belt 204 is installed outside the roller bodies of the drive roller 202 and the support roller 203. The scraping mechanism 3 includes a switching frame 302 and two scraping blocks 301. The two scraping blocks 301 are rotatably connected to the left and right sides inside the reciprocating seat 201, and the switching frame 302 is inserted into the inside of the reciprocating seat 201. The two scraping blocks 301 are located on both sides of the capture steel belt 204.

[0022] The discharge tank 101 is equipped with a drive rack 1011 at its top, and a drive gear 2021 is provided on the outside of the shaft of the drive roller 202. The drive gear 2021 and the drive rack 1011 mesh and drive each other. In use, the extension and retraction of the electric push rod 102 can drive the processing component to move back and forth on the top of the discharge tank 101, thereby achieving rapid capture and collection of residual ink on the surface of the wastewater. When the electric push rod 102 extends and retracts, it can drive the reciprocating seat 201 to move synchronously. When the reciprocating seat 201 moves, the drive gear 2021 and the drive rack 101 of the drive roller 202 drive each other. The gear meshing transmission of 1 allows the drive roller 202 to rotate as the reciprocating seat 201 moves. When the drive roller 202 rotates, it can drive the capture steel belt 204 to move in a cycle through the cooperation of the support roller 203. As a result, the ink on the water surface will adhere to the capture steel belt 204 and be carried out of the water surface as the capture steel belt 204 moves. Under the action of the scraper block 301, the ink on the surface of the capture steel belt 204 is scraped off and collected inside the reciprocating seat 201. The collected ink is finally discharged into the collection container through the oil drain port of the reciprocating seat 201 and the hose. It is convenient and flexible to use.

[0023] The scraping block 301 has a switching gear 3011 on its outer side of its rotating shaft, and a switching rack 3021 on its outer side of the switching frame 302. The gear teeth of the switching gear 3011 and the switching rack 3021 mesh and drive each other. The scraping block 301 located on one side of the reciprocating seat 201 in the direction of movement abuts against the capturing steel belt 204, while the scraping block 301 is separated from the capturing steel belt 204. In use, as the reciprocating seat 201 moves back and forth, the rotation direction of the drive roller 202 also changes. The scraping mechanism 3 can adjust the scraping mechanism according to the rotation of the drive roller 202. The two scraper blocks 301 automatically switch their usage states. Positioning magnets 3022 are provided on both sides of the switching frame 302, and magnetic positioning blocks 2011 are provided on both sides inside the reciprocating seat 201. Taking the reciprocating seat 201 moving to the right as an example, the positioning magnet 3022 and the magnetic positioning block 2011 on the right side magnetically engage, causing the scraper block 301 on the right side to contact the surface of the captured steel strip 204, while the scraper block 301 on the left side separates from the captured steel strip 204. At this time, the drive roller 202 rotates clockwise, thereby achieving the capture of the steel strip 204. For the surface ink scraping and collection operation, switching rods 3023 are provided on both sides of the switching frame 302, and the rods of the switching rods 3023 pass through the interior of the reciprocating seat 201. When the reciprocating seat 201 moves to the far right, the switching rod 3023 on the right side of the switching frame 302 is blocked by the body of the discharge pool 101, thereby causing the switching frame 302 to move to the left inside the reciprocating seat 201. When the switching frame 302 moves, under the cooperation of the switching gear 3011 and the switching rack 3021, the scraping block 301 on the left side will rotate and abut against the capture block. On the surface of the steel strip 204, the right-side scraper block 301 rotates to release its contact with the captured steel strip 204, and the left-side positioning magnetic block 3022 and magnetic positioning block 2011 magnetically engage to maintain the current use state of the scraping mechanism 3. Subsequently, when the reciprocating seat 201 moves to the left, the drive roller 202 rotates counterclockwise, so that the left-side scraper block 301 can perform the scraping and collection operation on the surface of the captured steel strip 204. Until the reciprocating seat 201 moves to the leftmost end, the switching action will be triggered again. The degree of automation is high and no manual intervention is required.

[0024] The working principle of this embodiment is as follows: After wastewater is discharged into the discharge tank 101, the residual ink on the surface of the wastewater can be captured and collected by the treatment component. After the residual ink is collected, it can be discharged from the discharge tank 101 for subsequent processing. The extension and retraction of the electric push rod 102 can drive the treatment component to move back and forth on the top of the discharge tank 101, thereby achieving rapid capture and collection of residual ink on the surface of the wastewater. When the electric push rod 102 extends and retracts, it can drive the reciprocating seat 201 to move synchronously. When the reciprocating seat 201 moves, the drive gear 2021 of the drive roller 202 and the drive rack 1011 mesh and drive the transmission, thereby enabling the drive roller 202... The reciprocating seat 201 can rotate while moving. The drive roller 202, in conjunction with the support roller 203, drives the capturing steel belt 204 to move cyclically. This causes ink on the water surface to adhere to the capturing steel belt 204, which is then carried out of the water as it moves. Under the action of the scraper block 301, the ink on the surface of the capturing steel belt 204 is scraped off and collected inside the reciprocating seat 201. The collected ink is finally discharged into the collection container through the oil outlet of the reciprocating seat 201 and a hose. Since the rotation direction of the drive roller 202 changes as the reciprocating seat 201 moves back and forth, the scraping mechanism 3 can automatically adjust its rotation direction according to the rotation direction of the drive roller 202. The two scraping blocks 301 are switched dynamically. Taking the reciprocating seat 201 moving to the right as an example, the positioning magnetic block 3022 and the magnetic positioning block 2011 on the right side are magnetically attracted, causing the scraping block 301 on the right side to abut against the surface of the capturing steel belt 204, while the scraping block 301 on the left side separates from the capturing steel belt 204. At this time, the drive roller 202 rotates clockwise, thereby realizing the scraping and collection operation of ink on the surface of the capturing steel belt 204. When the reciprocating seat 201 moves to the far right, the switching abutment rod 3023 on the right side of the switching frame 302 is blocked by the body of the discharge pool 101, thereby causing the switching frame 302 to move to the left inside the reciprocating seat 201. When the changing frame 302 moves, under the combined action of the switching gear 3011 and the switching rack 3021, the left scraper block 301 will rotate and abut against the surface of the capture steel belt 204, while the right scraper block 301 will rotate to release its abutment against the capture steel belt 204. The left positioning magnetic block 3022 and the magnetic positioning block 2011 will magnetically engage to maintain the current use state of the scraping mechanism 3. Afterwards, when the reciprocating seat 201 moves to the left, the drive roller 202 rotates counterclockwise, so that the left scraper block 301 can perform the scraping and collection operation on the surface of the capture steel belt 204. The switching action will be triggered again after the reciprocating seat 201 moves to the leftmost end.
