[0001] This utility model belongs to the field of tin can coating technology, specifically, it relates to a food tin can coating device with adjustable hot air distance. Background Technology

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicinal materials, but does not include items intended for therapeutic purposes.

[0003] A coating device is needed when processing food tin cans to apply patterns to the can body. However, while existing coating devices can coat tin cans, they still present some technical challenges in use, such as:

[0004] Sometimes the inks used in coating are not quick-drying. In this case, a drying device is needed to quickly dry the ink. However, the drying equipment on existing coating devices is in a fixed position. When the size of the food can is large, the distance between it and the drying equipment will be smaller. The heat will be transferred to the can relatively concentratedly, causing the temperature of the can to rise rapidly in a short time. Different inks have different drying speeds, which will affect the drying effect of the ink and thus affect the product quality of the can.

[0005] There are currently no effective solutions to the problems in the relevant technologies.

[0006] Therefore, in order to solve the above problems, this utility model provides a food can coating device with adjustable hot air distance. Utility Model Content

[0024] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0025] Please see Figure 1 , Figure 2 and Figure 3 According to an embodiment of this utility model, a food tin can coating device with adjustable hot air distance includes a frame 1, a side frame 2, and a clamping and rotating mechanism 4 for supporting the food tin can 3. The clamping and rotating mechanism 4 is mounted on the frame 1. The frame 1 serves as the basic support structure of the entire device, providing a stable mounting platform for all components such as the clamping and rotating mechanism and the position adjustment mechanism, ensuring the structural stability of the overall operation of the device, and is a prerequisite for the coordinated work of all components. The clamping and rotating mechanism 4 is used to support and fix the food tin can 3, while driving the tin can to rotate at a uniform speed, so that the surface of the tin can is evenly in contact with the coating mechanism during coating, and evenly receives hot air during drying. This improves the uniformity of printing and drying, avoiding problems such as incomplete local processing. The side frame 2 is fixedly connected to the frame 1, and the template mechanism 7 and the brushing mechanism 8 are installed on the side of the side frame facing the clamping and rotating mechanism 4. The side frame 2 facing the clamping and rotating mechanism 4 provides a mounting carrier for the template mechanism 7 and the brushing mechanism 8, ensuring the installation accuracy and positional stability of the printing-related components, thus ensuring accurate printing. The template mechanism 7 provides a pattern reference for the printing process. Through precise contact with the surface of the tin can, it ensures the accurate shape and position of the printed pattern. The brushing mechanism 8 is the core component that directly realizes ink application, and its adjustment unit can flexibly... The height of the coating plate can be adjusted to accommodate the surface adhesion requirements of different sized tin cans. A through slot 11 is provided on the frame 1, and a position adjustment mechanism 9 is installed on the frame 1. At least a portion of the position adjustment mechanism 9 is located within the through slot 11, and a hot air blower 10 is mounted on the position adjustment mechanism 9. The position adjustment mechanism 9 includes a vertical adjustment component for adjusting the height of the hot air blower 10 and a horizontal adjustment component for adjusting the horizontal position of the hot air blower 10. The horizontal adjustment component includes an electric telescopic rod 909 and a mounting base 910. The hot air blower 10 is detachably mounted on the mounting base 910 by bolts. The adjustment mechanism 9 is the core component of the device that enables adjustable hot air distance. Its vertical adjustment component allows for precise and controllable adjustment of the vertical height of the hot air blower, ensuring stable operation and high adjustment accuracy. The horizontal adjustment component allows for convenient adjustment of the horizontal position of the hot air blower. The combined effect of the two components allows the hot air blower to be flexibly positioned in three-dimensional space, with a wide adjustment range and convenient operation, and can accurately match the drying requirements of different sized iron cans and different inks. The hot air blower 10, as the core drying component, achieves rapid drying of ink by outputting hot air. It adopts a bolt-on detachable assembly design, which facilitates later maintenance and replacement. Its advantages are strong practicality and low operating cost.

[0026] Please see Figure 1 and Figure 2The frame 1 is equipped with a first electric guide rail 5, and the clamping and rotating mechanism 4 is mounted on the first electric guide rail 5. The first electric guide rail 5 is used to drive the clamping and rotating mechanism 4 to move along the axial direction of the food can 3. The core function of the first electric guide rail 5 is to drive the clamping and rotating mechanism 4 to move along the axial direction of the can, so that the can can be axially fed during the processing, ensuring that all parts of the can can fully contact the coating and drying process. The advantage is that it can adapt to cans of different lengths and improve the comprehensiveness and uniformity of the processing.

[0027] Please see Figure 1 and Figure 2 A second electric guide rail 6 is installed on the side of the side frame 2 facing the clamping and rotating mechanism 4. The template mechanism 7 is mounted on the second electric guide rail 6. The second electric guide rail 6 is used to drive the template mechanism 7 to move radially along the food can 3. The distance between the template and the can body can be flexibly adjusted according to the diameter of the can, which can accurately adapt to cans of different thicknesses and avoid pattern deformation or unclear printing caused by improper distance between the template and the can body.

[0028] Please see Figure 1 The coating mechanism 8 includes a coating plate and an adjustment unit for adjusting the height of the coating plate. The adjustment unit is an adjustment screw or a cylinder. The adjustment unit can precisely adjust the height of the coating plate, allowing the coating plate to be adapted to the surface of iron cans of different heights or diameters. It has strong adaptability and can avoid uneven coating caused by differences in iron can specifications, thus ensuring coating quality.

[0029] Please see Figure 2 and Figure 3The vertical adjustment assembly includes a vertical rod 901 fixedly installed in a through groove 11. A slide groove 902 is provided on one side of the vertical rod 901. A first fixed seat 903 is fixedly installed at the bottom of the slide groove 902. A motor 904 is fixedly installed at the top of the first fixed seat 903. A reducer 905 is installed at the top of the motor 904. A connecting shaft 906 is installed at the top of the reducer 905. A lead screw 907 is installed at the top of the connecting shaft 906. A slider 908 is threaded onto the lead screw 907. A second fixed seat 911 is fixedly installed at the top of the slide groove 902. The top of the lead screw 907 is rotatably connected to the second fixed seat 911. The vertical rod 901 and the slide groove 902 provide guidance and limit for the movement of the slider 908. To prevent the slider 908 from shifting during lifting and lowering, and to ensure the stability and accuracy of vertical adjustment, the first fixed seat 903 and the second fixed seat 911 respectively fix the top of the motor 904 and the lead screw 907, providing stable support for the transmission structure of the vertical adjustment component, ensuring smooth power transmission and structural stability. The motor 904, as the power source for vertical adjustment, works with the reducer 905 to adjust the output speed, ensuring that the lead screw 907 rotates smoothly, thereby driving the slider 908 to lift and lower at a uniform speed. The power output is stable and the adjustment is precise. The lead screw 907 is threadedly connected to the slider 908, converting the rotational motion of the motor 904 into the linear motion of the slider. This results in high transmission efficiency, precise positioning, and the ability to achieve fine adjustment of the height of the hot air blower 10.

[0030] Please see Figure 3 The slider 908 is fixedly connected to the electric telescopic rod 909 of the horizontal adjustment component, realizing the linkage between the vertical adjustment component and the horizontal adjustment component, so that the hot air blower 10 can move up and down as well as move horizontally.

[0031] The working principle of a hot air distance adjustable food tin can coating device is as follows: First, the food tin can 3 to be processed is fixed on the clamping and rotating mechanism 4. After the clamping and rotating mechanism 4 is started, it drives the tin can to rotate at a uniform speed, providing the basic conditions for subsequent uniform coating and drying. Then, according to the diameter specification of the tin can, the template mechanism 7 is driven to move radially through the second electric guide rail 6, so that the template fits the surface of the tin can, ensuring the accurate positioning of the coating pattern. At the same time, the height of the coating plate is adjusted by the adjustment unit (adjusting screw or cylinder) of the coating mechanism 8, so that the coating plate fits tightly with the surface of the tin can. The uniform coating of ink can be achieved by starting the coating mechanism 8.

[0032] After printing, the drying process begins. Based on the size and specifications of the tin can and the drying requirements of the ink, the position of the hot air blower 10 is adjusted via the position adjustment mechanism 9. In the vertical adjustment assembly, the motor 904 drives the lead screw 907 to rotate via the reducer 905. The lead screw 907 drives the slider 908 to move up and down along the slide groove 902, thereby adjusting the vertical height of the hot air blower 10. In the horizontal adjustment assembly, the electric telescopic rod 909 drives the mounting base 910 to move horizontally, adjusting the horizontal distance between the hot air blower 10 and the tin can, ensuring a suitable drying distance. During this process, the first electric guide rail 5 drives the clamping and rotating mechanism 4 to move uniformly along the axial direction of the tin can. This, combined with the rotation of the tin can, ensures that all parts of the can receive hot air evenly, achieving rapid and uniform ink drying. The coordinated operation of all components ultimately completes the precise printing and efficient drying of the food tin can, ensuring product quality.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
