Description

Technical Field

[0001] This utility model relates to the field of food can surface printing, and in particular to a food can surface printing flipping device. Background Technology

[0002] Food cans, including aluminum cans, serve the core function of extending food shelf life and ensuring safety. Through their sealed design, they isolate air, moisture, and microorganisms, preventing food from becoming damp, oxidized, or contaminated. Meanwhile, their materials (such as stainless steel and glass) possess corrosion-resistant and high-temperature-resistant properties, ensuring that food maintains its freshness and nutritional value during storage. Furthermore, food cans are easy to categorize, store, and carry, making them suitable for use in homes, outdoors, and other settings. The printing on the surface of food cans, through information standardization, visual design, and protective technology, simultaneously enhances product safety, market competitiveness, and user experience.

[0003] Chinese patent CN221453116U discloses a can body transfer coating process platform. When the outer wall of the rubber wheel contacts the outer wall of the support plate during the transfer coating process, the outer wall of the rubber wheel pushes the support plate inward under the action of the outer wall of the rubber wheel, which compresses the drive spring. This makes the outer wall of the rubber wheel contact more tightly with the outer wall of the can that is sleeved on the outer wall of the can shaft, thus enabling better coating of the outer wall of the can.

[0004] In the above solution, after placing the can on the sleeve shaft, the can is fixed by pressing the inner wall of the can simultaneously with three support pads. However, the can wall is relatively thin, which causes deformation in the local area where the can is pressed by the support pads. This makes it difficult to ensure the flatness of the surface after the can is fixed, resulting in uneven transfer of printing ink. Therefore, a food can surface printing flipping device is proposed to solve the above problems. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] 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.

[0022] Please see Figure 1-4In this utility model, a food can surface printing flipping device includes a turntable 1 and a drive plate 2. The turntable 1 has a color plate 101 on its side. The color plate 101 is an arc-shaped structure made of silicone rubber. At least three color plates 101 are provided. Two motors drive the turntable 1 and the drive plate 2 to rotate respectively. The drive plate 2 has a number of insert plates 5 inside. A stabilizing plate 3 and a roller 4 are provided on one side of the insert plate 5. An electric telescopic rod 6 is provided on one side of the insert plate 5. A transmission shaft 7 is provided inside the roller 4.

[0023] Example 1: Please refer to Figure 1-4 In this embodiment of the utility model, a food can surface printing flipping device is provided. The stabilizing plate 3 is an arc-shaped plate structure. The outer convex surface of the stabilizing plate 3 is attached to the inner wall of the food can. A first support rod 301 and a second support rod 302 are provided on one side of the inner concave surface of the stabilizing plate 3. One end of the first support rod 301 and the second support rod 302 are axially connected to the inner concave surface of the stabilizing plate 3.

[0024] Roller 4 is a hollow cylindrical structure with one end open. A pad 401 is provided at the closed end of roller 4. The open end of roller 4 is connected to the bearing of insert plate 5. A first extension plate 403 and a limiting groove 402 are provided on the side of roller 4. The other end of the first support rod 301 is axially connected to the first extension plate 403.

[0025] The electric telescopic rod 6 is fixed on the insert plate 5. The connecting plate 601 is connected to the piston rod inside the electric telescopic rod 6. One end of the drive shaft 7 is located inside the roller 4 and is provided with a second extension plate 702. The other end of the drive shaft 7 extends to the outside of the roller 4 and is connected to the bearing of the connecting plate 601. A collar 701 is provided between the drive shaft 7 and the roller 4. The second extension plate 702 passes through the limiting groove 402 and is axially connected to the other end of the second support rod 302.

[0026] The electric telescopic rod 6 drives the transmission shaft 7 to move outward from inside the roller 4, thereby causing the three stabilizing plates 3 to simultaneously press against the inner wall of the can, thus fixing the position of the can. The outer convex surface of the stabilizing plate 3 is always in contact with the inner wall of the can, thus ensuring the flatness of the can surface during subsequent printing, and improving the uniformity of subsequent ink transfer.

[0027] During the printing process on the surface of aluminum cans, after the stabilizing plate 3 fixes the position of the aluminum can, the driving plate 2 moves the aluminum can to the printing position, and the turntable 1 rotates the color plate 101 until the color plate 101 moves to the printing position, so that the color plate 101 contacts the surface of the aluminum can at the printing position. Then the color plate 101 moves the aluminum can to rotate, so that the ink is transferred to the surface of the aluminum can, thereby completing the printing. Afterwards, the driving plate 2 moves the unprinted aluminum can to the printing position, and the turntable 1 moves the color plate 101 with ink to the printing position, thereby performing the printing operation again. The driving plate 2 stops rotating after transporting the unprinted aluminum can to the printing position, while the turntable 1 is in a continuous rotating state. There is a groove between every two adjacent color plates 101 on the surface of the turntable 1. After the previous color plate 101 is printed, the turntable 1 rotates and moves the groove to the printing position. At this time, the driving plate 2 transports the unprinted aluminum can to the printing position, thereby avoiding misalignment and collision between the aluminum can and the color plate 101.

[0028] The working principle of this utility model is as follows: the electric telescopic rod 6 drives three stabilizing plates 3 to simultaneously press the inner wall of the can, thereby fixing the position of the can. The outer convex surface of the stabilizing plate 3 is always in contact with the inner wall of the can, thus ensuring the flatness of the can surface during subsequent printing. Then, the drive plate 2 drives the can to the printing position, and the turntable 1 drives the color plate 101 to rotate until the color plate 101 moves to the printing position, so that the color plate 101 contacts the surface of the can at the printing position. Then, the color plate 101 drives the can to rotate, so that the ink is transferred to the surface of the can, thereby completing the printing.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
