Description

Technical Field

[0001] The utility model relates to the technical field of food inkjet coding, in particular to a food inkjet coding device. Background Art

[0002] The mobile inkjet coding device of a food packaging machine is used for marking, inkjet coding, printing characters, patterns, etc. on food packaging bags or packaging films. However, the food packaging bags are prone to certain shaking during the transmission process, resulting in a certain deviation in the position between the packaging bags and the inkjet printer, causing a certain offset in the inkjet coding position, affecting the packaging aesthetics and subsequent use.

[0003] In order to solve such problems, a prior Chinese patent application No. 202222229590.8 discloses an inkjet coding device for food packaging, which relates to the technical field of food packaging inkjet coding. The patent includes a transmission frame and a mounting frame. The mounting frame is installed on the upper surface of the transmission frame. A mounting seat is fixedly connected to the bottom surface of the mounting frame. A first chute is provided inside the mounting seat. A sliding seat is slidably fitted inside the first chute. An inkjet printer is installed below the sliding seat. A second chute is provided inside the mounting frame. A bidirectional threaded rod is rotatably connected to the inner side wall of the second chute. Two groups of sliding plates are threadedly fitted on the circumferential surface of the bidirectional threaded rod. A limiting plate is provided below the sliding plate. By setting the second chute, the bidirectional threaded rod, the sliding plates, the limiting plate and the second motor, the limiting plate is driven to move the food packaging bag to the central position, ensuring the accurate inkjet coding position and avoiding the situation of inkjet deviation, and ensuring the inkjet coding qualified rate.

[0004] Although the above patent can move the food packaging bag to the central position, ensure the accurate inkjet coding position, avoid the situation of inkjet deviation, and ensure the inkjet coding qualified rate, in actual use, the patent can only move the food packaging to the central position when it is below the mounting frame, and cannot limit the food packaging during the transmission process. That is, the transmission frame and the transmission belt of the patent are on the same horizontal line, so that the food packaging may deviate during the transmission process. When it is then transmitted to below the mounting frame and then synchronously pushed by the two limiting plates, it may cause the food packaging to rotate by 45 degrees or 90 degrees, resulting in a certain difference in the inkjet coding position of the food packaging, reducing the accuracy of the inkjet coding, and making the patent still have certain limitations in actual use.

[0005] Therefore, it is necessary to transform the inkjet coding device in the above patent to effectively prevent the situation that the food packaging can only be moved to the central position when it is below the mounting frame, and cannot limit the food packaging during the transmission process, so that it may deviate during the transmission process.
