Description

Technical Field

[0001] This utility model relates to the field of nutrition pack coding technology, and more specifically, to a positioning device for automatic coding of nutrition packs. Background Technology

[0002] The automatic inkjet printing device for nutrition packs is an intelligent device designed to quickly and accurately print information such as production date, batch number, and shelf life on the outer packaging of nutrition packs. It adopts non-contact inkjet printing technology, supports high-resolution marking, ensures clear and durable lettering, and has automatic detection, positioning, and printing functions. It can be seamlessly integrated into the production line, improving efficiency while meeting food safety standards, and is suitable for large-scale production scenarios.

[0003] The existing automatic coding devices for nutrition packs lack a positioning device for the nutrition packs during use, which makes the nutrition packs prone to deviation or tilting when moving on the conveyor belt. Due to the lack of a precise fixing mechanism, when the coding station prints information such as production date and batch number, the coding may be misaligned, blurry, or incomplete due to the inaccurate position of the nutrition pack, thereby reducing the coding pass rate and increasing the risk of rework or waste.

[0004] In summary, to improve the accuracy and production efficiency of automatic coding of nutritional packs, it is necessary to solve the coding deviation problem caused by the lack of positioning devices in existing equipment, so that the printed information can always be clearly and accurately presented in the designated position on the packaging, thereby ensuring the standardization and traceability of product identification and reducing losses caused by unqualified coding.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual appendix Figures 1 to 5 The positioning device for automatic inkjet coding of nutritional packages includes a conveyor belt 1, multiple support legs 2 fixed on the conveyor belt 1, a fixed plate 3 fixedly installed on the top of the support legs 2, two guide sleeves 4 installed on the fixed plate 3, guide posts 5 slidably connected to the inner side of the guide sleeves 4, a pressure plate 11 connected to the bottom of the guide posts 5 through the fixed plate 3, a connecting plate 6 connected between the two guide posts 5, a rack 7 fixed on the right side of the connecting plate 6, a mounting base 8 fixed on the top of the fixed plate 3, a first drive motor 9 installed on the front side of the mounting base 8, a gear post 10 installed at the output end of the first drive motor 9, the first drive motor 9 is used to drive the gear post 10 to rotate, the gear post 10 meshes with the rack 7, an inkjet module is installed at the bottom of the fixed plate 3, a bracket 12 is set on the top of the conveyor belt 1, a vision module 13 is set on the bracket 12, a cleaning mechanism is set on the bracket 12, and a dust blowing mechanism is set on the left side of the bracket 12.

[0022] It should be noted that when the first drive motor 9 is working, it can drive the toothed column 10 to rotate. When the toothed column 10 rotates, it can drive the rack 7 that meshes with it to move up and down. Thus, through the connecting plate 6, it drives the two guide columns 5 to move up and down under the restriction of the guide sleeve 4. During inkjet printing, the guide columns 5 drive the pressure plate 11 to press down, thereby positioning the nutrient pack and reducing the error caused by inkjet printing.

[0023] Refer to the instruction manual appendix Figure 4 and Figure 5 The cleaning mechanism includes a wiping component and a drive component. The drive component is used to drive the wiping component to rotate, and the wiping component is used to clean the lens of the vision module 13.

[0024] It should be noted that when the drive component is in operation, it can drive the wiping component to rotate, and the wiping component can clean the vision module 13 when it rotates.

[0025] Refer to the instruction manual appendix Figure 4 and Figure 5 The wiping assembly includes a rotating shaft 141 that is rotatably connected to the bracket 12, a turntable 142 fixed to the bottom of the rotating shaft 141, and a brush rod 143 provided at the bottom of the turntable 142.

[0026] It should be noted that the rotation of the rotating shaft 141 can drive the turntable 142 to rotate synchronously, and the turntable 142 drives the brush rod 143 to rotate. The brush rod 143 is in contact with the lens of the vision module 13, and can wipe away the dust on the surface of the lens when it rotates.

[0027] Refer to the instruction manual appendix Figure 4 and Figure 5 The drive assembly includes a mounting bracket 144 fixed on the bracket 12, a second drive motor 145 mounted on the mounting bracket 144, a drive gear 146 mounted on the output end of the second drive motor 145, and a driven gear 147 mounted on the top of the rotating shaft 141. The drive gear 146 meshes with the driven gear 147, and the second drive motor 145 is used to drive the drive gear 146 to rotate.

[0028] It should be noted that when the second drive motor 145 is in operation, it can drive the drive gear 146 to rotate. When the drive gear 146 rotates, it meshes with the driven gear 147 to drive the rotating shaft 141 to rotate.

[0029] Refer to the instruction manual appendix Figure 1 and Figure 4 The dust blowing mechanism includes an installation component and an air outlet component. The installation component is used to install the air outlet component, and the air outlet component is used to blow away dust from the surface of the nutrient pack.

[0030] It should be noted that the air outlet component is located inside the installation component, and can generate airflow to blow on the surface of the nutrient pack during operation.

[0031] Refer to the instruction manual appendix Figure 1 The mounting components include a fixing frame 151 located on the left side of the bracket 12, and a dustproof net 152 is provided on the inner side of the fixing frame 151.

[0032] It should be noted that the dustproof net 152 is designed to prevent dust from falling into the interior of the fixed frame 151.

[0033] Refer to the instruction manual appendix Figure 4 The air outlet assembly includes a fan 153 disposed inside the fixed frame 151, and the fan 153 is fixed to the fixed frame 151 by bolts.

[0034] It should be noted that the blower 153 can generate high-speed airflow during operation, thereby blowing away the dust on the surface of the nutrient pack and preventing the dust from affecting the printing.

[0035] Working principle: During the process of conveyor belt 1 transporting the nutrient pack to the coding station, the fan 153 starts to generate airflow, which blows dust off the surface of the nutrient pack through the fixed frame 151. Then, the first drive motor 9 starts, driving the toothed column 10 to rotate. The rack 7 meshing with the toothed column 10 moves up and down accordingly. Through the connecting plate 6, the two guide columns 5 slide vertically in the guide sleeve 4, and finally drive the pressure plate 11 to press down, stabilizing the nutrient pack under the fixed plate 3. After positioning, the second drive motor 145 works, driving the drive gear 146 to rotate. Through the meshing driven gear 147, the rotating shaft 141 and the turntable 142 rotate, so that the brush rod 143 fixed at the bottom of the turntable 142 wipes the lens of the vision module 13 to ensure cleanliness. After cleaning, the vision module 13 detects and confirms the positioning status of the nutrient pack. Finally, the coding module completes accurate coding at the set position.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
