Description

Technical Field

[0001] This utility model relates to the technical field of inkjet coding mechanism for sealing tissues, specifically an inkjet coding mechanism for sealing wet tissues. Background Technology

[0002] Inkjet coding of wet wipe packaging is usually the final step in wet wipe production. The inkjet coding system for sealing wet wipes records information such as the production date and batch number on the packaging. Typically, an inkjet coding device for sealing wet wipes includes a coding station and a conveyor belt, which transports the wet wipe packages to the coding station for coding.

[0003] However, in existing inkjet printers, some ink remains inside the printer after the solenoid valve is closed. When the printer is stopped or in standby mode, this residual ink easily drips off due to gravity, contaminating the packaging surface or production line equipment. Since wet wipes are often packaged in light-colored materials, even slight contamination can lead to product spoilage. If the residual ink does not drip off, it will clump together upon contact with moisture, clogging the printer and affecting subsequent coding results.

[0004] Furthermore, during high-speed printing, some ink droplets deviate from the target area due to jet pressure or airflow interference, resulting in splatter and increasing the frequency of cleaning and maintenance. Therefore, we propose a coding mechanism for sealing wet wipes. Utility Model Content

[0008] Preferably, the anti-drip mechanism includes an anti-drip plate, a sliding groove is provided at the top of the support frame, the anti-drip plate and the sliding groove are slidably connected, and a pneumatic push rod is fixedly connected to one side of the anti-drip plate.

[0009] Preferably, an absorbent sponge is detachably installed on the leak-proof plate, and the leak-proof plate is connected to an air pump via a pipe.

[0010] Preferably, the anti-splash mechanism includes a protective ring, with sliding plates fixedly connected to both sides of the protective ring.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 A coding mechanism for sealing wet wipes includes a conveyor belt 1 for transporting the sealed wet wipes. A support frame 2, which has a "U"-shaped structure, is fixedly installed on the conveyor belt 1. A coding pad 3 is fixedly installed at the top of the support frame 2, and the coding pad 3 is used to code the wet wipes. An anti-drip mechanism 4 is provided on the support frame 2 to shield the coding pad 3 when it stops working, preventing dripping and contamination of the conveyor belt 1, and to absorb residual ink droplets inside the coding pad 3, preventing residual ink from mixing with moisture in a high humidity environment, causing clumping, and thus clogging the coding pad 3.

[0026] The support frame 2 is also equipped with an anti-splash mechanism 5, which is used to protect the surroundings when the inkjet terminal 3 is being printed, and to block the ink that is splashed out, so as to avoid the external environment from affecting the printing.

[0027] Please see Figure 2 The anti-drip mechanism 4 includes a slide groove 43, which is located at the center of the top of the support frame 2. An anti-drip plate 41 is slidably installed in the slide groove 43. The anti-drip plate 41 has an "L"-shaped structure. By moving the anti-drip plate 41 along the slide groove 43, the anti-drip plate 41 and the spray nozzle 3 can be quickly moved closer and further apart, thereby achieving an anti-drip effect on the spray nozzle 3. A pneumatic push rod 44 is fixedly connected to one side of the anti-drip plate 41, which is used to push the anti-drip plate 41 to move along the slide groove 43. The pneumatic push rod 44 has the characteristics of fast response and adaptability to frequent use.

[0028] An absorbent sponge 42 is fixedly installed on the leak-proof plate 41. The absorbent sponge 42 is located at the bottom of the spray nozzle 3, allowing it to absorb residual ink on the spray nozzle 3 and prevent ink from clumping inside the spray nozzle 3. The absorbent sponge 42 is connected to an air pump 45 through a pipe to create negative pressure, which can better absorb residual ink inside the spray nozzle 3 and prevent excessive ink from remaining inside the absorbent sponge 42 and clumping, thus affecting the working life of the absorbent sponge 42. Furthermore, the residual ink can be recycled, saving costs.

[0029] Please see Figures 3-4 The anti-splatter mechanism 5 includes a second slide groove 53, which is located on both sides of the support frame 2. A sliding plate 52 is slidably installed inside the slide groove 53. A protective ring 51 is fixedly installed on one side of the sliding plate 52. A pneumatic push rod 54 is fixedly connected to the sliding plate 52. The pneumatic push rod 54 can drive the sliding plate 52 to move along the slide groove 53. The movement of the sliding plate 52 causes the protective ring 51 to move, thereby protecting the inkjet pad 3 from the wet paper towel and preventing the external environment from affecting the printing during inkjet printing. Furthermore, the inner side of the protective ring 51 is made of sponge, which can protect against ink droplets that may splash during printing and prevent splashed ink droplets from affecting the printing effect.

[0030] A ring plate 55 is fixedly installed at the bottom of the support frame 2. Multiple airflow nozzles 56 are fixedly installed on the ring plate 55. The ring plate 55 is connected to the air pump 45 through a pipe. The multiple airflow nozzles 56 are arranged in an array, so that when printing, the airflow nozzles 56 can form a downward ring airflow barrier around the printing dock 3, which can protect the gap between the protective ring 51 and the support frame 2 and avoid the influence of the external environment.

[0031] A coding mechanism for sealing wet wipes, the working principle of which is as follows:

[0032] During coding, pneumatic push rod 44 operates, causing the anti-leak plate 41 to move along the slide groove 43, thus detaching the anti-leak plate 41 from the bottom of the inkjet pad 3 and preventing it from affecting the coding. Then, pneumatic push rod 54 operates, causing the sliding plate 52 to move along the slide groove 53. This movement of the sliding plate 52 moves the protective ring 51, protecting the inkjet pad 3 from the wet paper towel and preventing external environmental factors from affecting the coding. Furthermore, the inner side of the protective ring 51 has a sponge structure, protecting against ink splatter during coding and preventing it from affecting the coding effect. The repeated small-distance movement of pneumatic push rod 54 ensures that the transmission of the wet paper towel via the conveyor belt 1 is not affected, while also providing good protection during coding and enhancing the stability of the coding process.

[0033] After the coding is completed or during intermittent coding, the pneumatic push rod 44 operates, causing the anti-leak plate 41 to move along the slide groove 43. This brings the anti-leak plate 41 closer to the bottom of the inkjet nozzle 3 until the absorbent sponge 42 is located at the bottom of the inkjet nozzle 3. The air pump 45 then creates a negative pressure at the absorbent sponge 42, adsorbing and recovering any residual ink within the inkjet nozzle 3, preventing ink dripping and contamination. Furthermore, the air pump 45 generates a downward annular airflow through the airflow nozzles 56 on the annular plate 55, preventing ink drop point deviation and contamination. It also protects the gap between the protective ring 51 and the support frame 2 during inkjet nozzle 3 operation, preventing external environmental influences.
