[0002] As is well known, the automatic feeding mechanism of inkjet printers (such as UV inkjet printers, solvent inkjet printers, water-based inkjet printers, etc.) is a key system to ensure continuous and stable ink supply. It can reduce manual intervention, avoid ink interruption or air bubble problems, and improve production efficiency and print quality.

[0003] A utility model patent with patent authorization announcement number CN215662514U discloses an automatic feeding mechanism for an inkjet printer, including a mounting plate and a first connecting pipe.

A circular plate is provided inside the ink dispensing tank.

[0004] However, the existing automatic feeding mechanism of inkjet printers also has certain shortcomings. Although the existing automatic feeding mechanism of inkjet printers uses ink storage tanks to store and use ink, due to the characteristics of ink and the influence of storage time, it is easy to cause problems such as subsequent ink adhesion and solidification. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding mechanism for inkjet printers, which solves the problem that some automatic feeding mechanisms for inkjet printers, although using ink storage tanks to store and use ink, are prone to subsequent ink adhesion and solidification due to the characteristics of ink and storage time.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5An automatic feeding mechanism for an inkjet printer includes a base plate 1. Four evenly distributed bolts 2 are movably connected to the inner wall of the base plate 1. An ink reservoir 3 is fixedly connected to the upper end of the base plate 1. An ink dispensing tank 4 is fixedly connected to the upper end of the base plate 1 and to the right of the ink reservoir 3.

The feeding pipe 7 is fixedly connected to the base plate 1. A peristaltic pump 8 is provided on the outer side of the feeding pipe 7. A printhead 9 is fixedly installed at the lower end of the feeding pipe 7.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The ink dispensing tank 4 is internally equipped with a liquid level mechanism 10, which includes a positioning rod 101. The positioning rod 101 is slidably connected to the inner wall of the ink dispensing tank 4. A liquid level sensor 102 is fixedly installed at the lower end of the positioning rod 101. A fixing cylinder 103 is fixedly connected to the inner right side wall of the ink dispensing tank 4. A sealing ring 104 is fixedly connected to the inner wall of the fixing cylinder 103. An insertion rod 105 is slidably connected to the inner wall of the sealing ring 104. The insertion rod 105 is slidably connected to the positioning rod 101. A slider 106 is fixedly connected to the right end of the device. A spring 107 is welded to the right end of the slider 106. The other end of the spring 107 is welded to the fixed cylinder 103. With the cooperation of the slider 106 and the spring 107, the insertion rod 105 can be connected. With the setting of the positioning rod 101, the liquid level sensor 102 can be quickly positioned. In conjunction with the function of the insertion rod 105 and other structures, the positioning rod 101 can be inserted to make the liquid level sensor 102 stable.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The ink reservoir 3 is equipped with a mixing mechanism 11, which includes a servo motor 110. The servo motor 110 is fixedly installed in the middle of the upper end of the ink reservoir 3. The output shaft of the servo motor 110 is rotatably connected to the ink reservoir 3. The output shaft of the servo motor 110 is fixedly connected to a stirring paddle 111. The lower end of the stirring paddle 111 is fixedly connected to a connecting rod 112. The lower end of the connecting rod 112 is fixedly connected to a contact ball 113. A telescopic block 115 is slidably connected to the inner wall of the output shaft of the servo motor 110. The lower end of the telescopic block 115 is fixedly connected to a scraper 116. The scraper 116 contacts the ink reservoir 3. Through the combined use of the servo motor 110 and the stirring paddle 111, the ink can be stirred. In addition, with the action of the scraper 116, the inner bottom of the ink reservoir 3 can be scraped to avoid ink accumulation and solidification.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 There are four stirring paddles 111 arranged in a circular array on the output shaft of the servo motor 110. The stirring paddles 111 can be used to mix the ink. The inner wall of the ink tank 3 is welded with an elastic agitator 114. The elastic agitator 114 contacts the contact ball 113. The cooperation of the elastic agitator 114 and the contact ball 113 can be used to assist in stirring the ink. An elastic rope 117 is attached to the upper end of the scraper 116. The other end of the elastic rope 117 is attached to the output shaft of the servo motor 110. The scraper 116 can be connected and used by the elastic rope 117.

[0027] The specific implementation process of this utility model is as follows: When in use, the ink can be stored and used through the setting of the ink storage tank 3, and when the servo motor 110 drives the output shaft to rotate, it can drive the stirring paddle 111 to rotate, and stir and mix the ink.

[0028] When the stirring paddle 111 rotates, it can drive the connecting rod 112 to rotate, which in turn drives the contact ball 113 to rotate, so that the contact ball 113 squeezes the elastic agitator 114 to push the elastic agitator 114 to move. When the contact ball 113 disengages from the elastic agitator 114, the elastic agitator 114 resets and moves, so that the elastic agitator 114 shakes back and forth to assist in stirring the ink.

[0029] When the servo motor 110 drives the output shaft to rotate, it can drive the telescopic block 115 to rotate, which in turn drives the scraper 116 to rotate, so that the scraper 116 slides along the inner bottom of the ink tank 3 to scrape and move the ink accumulated on the inner bottom of the ink tank 3, thus preventing the ink from solidifying.

[0030] By pushing the insertion rod 105 to the right, the slider 106 slides along the inner wall of the fixed cylinder 103, causing the spring 107 to deform. Finally, the insertion rod 105 is inserted into the fixed cylinder 103. Then, the positioning rod 101 is pushed into the ink dispenser 4, and the insertion rod 105 is released so that the spring 107 returns to its original deformation, pushing the insertion rod 105 through the positioning rod 101. This causes the positioning rod 101 to stabilize the liquid level sensor 102. Under the action of the liquid level sensor 102, the liquid level of the ink can be automatically monitored.

[0031] With the delivery pump 6 and delivery pipe 5, the ink can be drawn and output, so that the ink flows into the ink distribution tank 4. Under the action of the peristaltic pump 8 and the feeding pipe 7, the ink can be automatically fed to the print head 9, and then the ink can be sprayed.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
