Description

Technical Field

[0001] This utility model belongs to the field of packaging production technology, and in particular relates to a bottom inkjet printer for packaging production. Background Technology

[0002] Beverages are foods meant for people to consume. Packaging beverages falls under the category of beverage production and processing. During the packaging process, workers use plastic bottles, paper bottles, or aluminum cans to hold the beverages. To prevent people from accidentally consuming expired beverages, the production date is printed on the packaging bottle. Before drinking bottled beverages, people can check the production date and expiration date to determine whether the bottled beverage is within its shelf life, thus improving the safety of bottled beverage consumption. Speaking of printing, one must mention the can bottom inkjet printer used in packaging production. The can bottom inkjet printer used in packaging production mainly consists of a base plate, base, column, main unit, scanning galvanometer, field lens, and display bracket.

[0003] A search revealed a patent document with patent publication number CN219564538U that discloses a coding machine for beverage production, including a support base. Both ends of the top of the support base are fixedly provided with fixed bases. The top sides of the two fixed bases are each fitted with a first electric telescopic rod. The output end of each first electric telescopic rod is fixedly provided with a support frame. The inner walls of the support frame are each fitted with a second electric telescopic rod.

[0004] However, it still has the following shortcomings in practical use:

[0005] 1. A base is fixed to the upper surface of the substrate, and a column is fixed to the upper surface of the base. A movable seat is fitted inside the column, and a slider is fixed to the side wall of the movable seat. A groove is opened on the side wall of the column, and the slider is slidably connected inside the groove. A connecting plate is connected to the side wall of the slider, and bolts are connected to the side wall of the connecting plate in a rectangular array. The bolts fix the main unit to the side wall of the connecting plate, increasing the stability of the main unit and thus improving the reliability of the coding process. However, the use of a large number of bolts makes the operation steps of disassembling and assembling the main unit cumbersome, inconvenient to quickly disassemble and assemble the main unit, and increases the workload of the staff.

[0006] 2. A scanning galvanometer is installed on the side wall of the main unit. A field lens is connected to the lower surface of the scanning galvanometer. The field lens faces downwards and is suitable for printing codes on the upper surface of objects when they are placed upright. However, when the objects are placed on their side, the orientation of the field lens cannot be adjusted according to the position of the object being printed, which reduces the applicable range and reduces the practicality.

[0007] To address these issues, we provide a bottom-printing machine for packaging production. Utility Model Content

By setting up a connecting component, the operation steps of disassembling and assembling the host are simplified, making it convenient and quick to disassemble and assemble the host, reducing the workload of the staff. Furthermore, by setting up an inkjet printing component, the scope of application is increased and the practicality is improved, thereby solving the technical problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up a connecting component, allows the adjusting rod to rotate counterclockwise and move upward, causing the clamping plate to move upward and increasing the distance between the clamping plate and the bottom of the connecting frame, thus releasing the main unit and removing it from the connecting frame. Rotating the adjusting rod clockwise causes the clamping plate to move downward, reducing the distance between the clamping plate and the bottom of the connecting frame, thus fixing the main unit's position on the connecting frame and completing the installation of the main unit. This simplifies the operation steps, shortens the time required for main unit assembly and disassembly, facilitates quick assembly and disassembly of the main unit, and reduces the workload of workers.

[0020] 2. This utility model, by setting up a coding assembly, pulls the positioning frame, stretches the return spring, moves the positioning frame out of the through hole, releases the fixation of the connecting seat position, rotates the scanning galvanometer, and the connecting seat moves in an arc around the pivot pin as a fixed point. The scanning galvanometer and field lens move accordingly until the connecting seat rotates 90 degrees. The positioning frame is then released, the return spring resets, and the positioning frame is reinserted into the through hole, fixing the position of the scanning galvanometer and field lens. The orientation of the field lens can be adjusted according to the coding position of the object, increasing the applicability and improving practicality. Attached Figure Description
