Description

Technical Field

[0001] The present application relates to the technical field of printing defoaming, and in particular to a defoaming device for paper bag printing. Background Art

[0002] In the process of paper bag printing, ink is needed to print pictures and texts on paper bags, and the quality of ink determines the printing effect.

[0003] Since a large number of bubbles will be generated during the printing process, the foam will cause various problems such as reduced production efficiency, increased energy consumption, printing surface defects and difficulty in production and printing. The current practice is to add a defoaming agent to the ink and then reduce the amount of foam by stirring. However, the current structure of this type of device is single, and the defoaming agent is mostly added manually, and then the ink in the ink barrel is mixed and stirred, which requires a large amount of operation. In view of this, the present application proposes a defoaming device for paper bag printing. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 4 As shown, a defoaming device for paper bag printing proposed in one embodiment of the present application includes:

[0026] Ink barrel 1, ink barrel 1 is used to prepare ink required for printing;

[0027] A first substrate 2 is mounted on the ink barrel 1;

[0028] A second substrate 3, mounted on the first substrate 2;

[0029] The stirring shaft 4 is mounted on the first substrate 2 through a bearing. A stirring rod 7 located inside the ink barrel 1 is mounted on the outer peripheral side of the stirring shaft 4. The stirring shaft 4 drives the stirring rod 7 to rotate, thereby completing the stirring of the ink.

[0030] The delivery pipe 5 is arranged on the second substrate 3. The delivery pipe 5 passes through the stirring shaft 4, and a gap is left between the outer wall of the delivery pipe 5 and the inner wall of the stirring shaft 4. One end of the delivery pipe 5 is connected to a four-way solenoid valve 6, wherein the other three-way of the four-way solenoid valve 6 are respectively connected to the ink supply pipeline, the defoaming agent pipeline and the ink extraction pipeline. Therefore, when it is necessary to prepare the ink, the corresponding ink is delivered to the delivery pipe 5 through the four-way solenoid valve 6, and then input into the ink barrel 1 through the delivery pipe 5, and then the corresponding passage of the four-way solenoid valve 6 is closed, and the stirring shaft 4 drives the stirring rod 7 to complete the stirring. In this process, a large number of bubbles are generated, so the corresponding passage of the four-way solenoid valve 6 is opened, and the defoaming agent is added into the ink barrel 1. At this time, the stirring shaft 4 rotates normally to complete the defoaming action in the ink preparation process. When the ink is prepared, the corresponding pipeline is opened again through the four-way solenoid valve 6, and the prepared ink is extracted from the paper bag for printing;

[0031] In summary, the present application combines the defoaming structure with the structure required for ink preparation. During the ink stirring and preparation process, the defoaming agent is added and mixed with the ink, thereby completing the defoaming work, reducing manual workload, and improving the ink preparation efficiency. The delivery pipe 5 and the stirring shaft 4 are combined together to reduce the phenomenon of numerous pipelines, and the integrated structural design is conducive to later maintenance.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, a driving motor 8 is installed on the first substrate 2, and the output shaft of the driving motor 8 is connected to a driving gear 9, and a driven gear 10 is installed on the stirring shaft 4. The driving gear 9 and the driven gear 10 are meshed with each other through teeth. The driving motor 8 is used as a power to drive the driving gear 9 to rotate, and then indirectly drives the driven gear 10 to rotate, thereby finally realizing the rotation of the stirring shaft 4 and completing the stirring of the ink. In addition, the diameter of the driving gear 9 is larger than the diameter of the driven gear 10, so the rotation speed of the stirring shaft 4 can be increased.

[0033] like Figure 1-Figure 4As shown, in some embodiments, the delivery tube 5 is movably matched with the second substrate 3. When the stirring shaft 4 rotates, the delivery tube 5 reciprocates along the axis of the stirring shaft 4. The power for the up and down movement of the delivery tube 5 comes from the rotation of the stirring shaft 4, so that no additional power parts are required. Secondly, the purpose of the up and down movement of the delivery tube 5 is to change the height position of the liquid entering the ink barrel 1, so as to improve the mixing effect. For example, in the process of ink preparation, the traditional liquid supply is to directly supply the ink into the ink barrel 1, and the position of the liquid outlet does not change. However, the ink stock solution of the present application will continuously change the liquid outlet position with stirring, and the added liquid is distributed in different At the same position, it is more conducive to mixing. In order to realize the up and down movement of the conveying pipe 5, a circular plate 11 is sleeved on the stirring shaft 4, and a feeler rod 12 is installed on the circular plate 11. A mounting plate 13 is installed on the conveying pipe 5. The mounting plate 13 is constructed with a contact plate with a gradually decreasing length along the circumferential contour. A guide rod 14 is installed on the mounting plate 13, and the guide rod 14 slides through the second substrate 3. During the circular motion of the feeler rod 12 with the stirring shaft 4, the contact position between the feeler rod 12 and the contact plate is constantly changing. Due to the shape of the contact plate, the mounting plate 13 is driven to move up and down continuously, thereby realizing the continuous up and down movement of the conveying pipe 5.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
