Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically to an online metering and adjustment device for sauce packaging. Background Technology
[0002] In the food packaging industry, sauce packets, as condiments or side dishes, are widely used in instant noodles, fast food, and seasoning industries. The accuracy of their packaging measurement directly affects the product's ease of use and user experience, while measurement efficiency and stability are related to the overall capacity and cost of the production line. Traditional sauce packet packaging machines mainly use volumetric metering or simple weighing feedback technology, but these have the following technical shortcomings in practical applications:
[0003] 1. Insufficient metering accuracy: Volumetric metering devices rely on a fixed-volume cavity for filling sauces, making their accuracy susceptible to fluctuations in sauce viscosity, temperature, and gas content. For example, high-viscosity sauces may leave residue in the cavity, resulting in a lower actual output, while low-viscosity sauces may drip due to fluid inertia, causing a single-pack weight error exceeding ±5%. Some improved solutions adjust the dispensing time in real time using weighing sensors, but the dynamic response is lagging, making it difficult to simultaneously meet the dual requirements of high-speed filling (≥60 packs / minute) and high accuracy (≤±1%).
[0004] 2. Limited adaptability: The rheological properties (such as viscosity and particle content) of different batches of sauces vary significantly. Traditional equipment requires manual adjustment of parameters or replacement of parts, resulting in long changeover times (usually 15-30 minutes).
[0005] 3. Hygiene and maintenance issues: Open metering structures are prone to sauce residue during cleaning, increasing the risk of microbial contamination. Utility Model Content
[0006] In order to solve the technical problems of insufficient metering accuracy, limited adaptability, and hygiene and maintenance in the existing technology, this application provides an online metering adjustment device for sauce packaging.

[0009] In some embodiments of this utility model, the mounting base is provided with a drive motor that drives the second universal joint to rotate, and the drive motor is electrically connected to the control box of the packaging machine body.
[0010] In some embodiments of this utility model, a first transmission mechanism is provided between the drive element and the bracket.

[0026] Please refer to Figures 1-4 This embodiment provides an online metering adjustment device for sauce packaging, including: a packaging machine body 1; a metering mechanism 2 disposed on the packaging machine body 1, the metering mechanism 2 including a mounting base 201, a metering pump 202, a connecting rod 203, a slider 204 and a driving element 205, the metering pump 202 being disposed on the mounting base 201, the slider 204 being slidably disposed on the mounting base 201 and connected to the metering pump 202, the driving element 205 being disposed on the mounting base 201, the connecting rod 203 being connected to the output ends of the slider 204 and the driving element 205 respectively; and an adjustment mechanism 3 for adjusting the feed amount of the connecting rod 203 extending into the metering pump 202, the adjustment mechanism 3 including a bracket 301 disposed on the output end of the driving element 205, a lead screw 302, and an adjustment block 303, the bracket 301 having an adjustment groove 4, the adjustment block 303 being slidably disposed in the adjustment groove 4, the lead screw 302 passing through the adjustment groove 4 and being threadedly connected to the adjustment block 303.
[0027] In this embodiment, the packaging machine body 1 is used to integrate and install various components of the sauce packet packaging, and to automatically package and store the sauce packets in batches after integrating the various components.
[0028] In this embodiment, the metering mechanism 2 is used to accurately measure the sauce to be packaged, facilitating its subsequent placement into the packaging bag. Specifically, the mounting base 201 is used to mount components such as the metering pump 202 and the slider 204, allowing for coordinated operation of these components to achieve sauce packaging. The metering pump 202 is used to quantitatively obtain and dispense the sauce, ensuring a constant volume in the packaged sauce bag. The connecting rod 203 and the slider 204 form a crank-slider 204 mechanism, used to draw in the sauce and dispense it into the packaging bag. The driving element 205 provides a power source for the metering of the sauce bag, facilitating stable and continuous metering of large quantities of sauce, thus enabling continuous packaging.
[0029] In this embodiment, the adjustment mechanism 3 is used to adjust the single metering volume of the metering pump 202. By adjusting the sliding stroke of the slider 204, the stroke of the piston inside the metering pump 202 is adjusted, ultimately changing the volume of sauce dispensed per batch. Specifically, the bracket 301 is used to mount the lead screw 302 and the adjustment block 303. Under the action of the drive element 205, the bracket 301 swings on the mounting base 201, thereby swinging the adjustment block 303 on the mounting base 201. The swinging adjustment block 303 drives the connecting rod 203 to move, which in turn drives the slider 204 to move. The slider 204 then drives the piston of the metering pump 202 to slide. By adjusting the swing amplitude of the bracket 301, the stroke of the piston inside the metering pump 202 can be directly changed, thereby directly changing the volume dispensed per batch.
[0030] During adjustment, the lead screw 302 is driven to rotate, and the rotation of the lead screw 302 drives the adjusting block 303 to slide in the adjusting groove 4, thereby changing the movement path and stroke of the connecting rod 203, and thus changing the metering volume of the metering pump 202.
[0031] Please refer to Figures 1-4 In some embodiments of this example, the bracket 301 is provided with a first universal joint 5, a drive shaft 6 and a second universal joint 7 connected to the lead screw 302. The first universal joint 5 is provided on the bracket 301, and the second universal joint 7 is rotatably provided on the mounting base 201. The second universal joint 7 and the first universal joint 5 are connected by the drive shaft 6.
[0032] In this embodiment, the first universal joint 5, the drive shaft 6, and the second universal joint 7 can rotate freely. When the bracket 301 swings, the drive shaft 6 can achieve adaptive extension and retraction. By driving the second universal joint 7 to rotate, the second universal joint 7 drives the drive shaft 6 to rotate. The rotation of the drive shaft 6 drives the first universal joint 5 to rotate. The rotating first universal joint 5 drives the lead screw 302 to rotate. The rotation of the lead screw 302 drives the adjusting block 303 to slide in the adjusting groove 4.
[0033] Please refer to Figures 1-4In some embodiments of this example, the mounting base 201 is provided with a drive motor 8 for driving the second universal joint 7 to rotate, and the drive motor 8 is electrically connected to the control box 9 of the packaging machine body 1.
[0034] In this embodiment, the drive motor 8 is used to drive the second universal joint 7 to rotate, thereby driving the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 drives the first universal joint 5 to rotate. The first universal joint 5 drives the lead screw 302 to rotate. The lead screw 302 drives the adjusting block 303 to slide in the adjusting groove 4. The swing radius of the adjusting block 303 changes, and the movement path and stroke of the connecting rod 203 and the slider 204 change accordingly.
[0035] Please refer to Figures 1-4 In some embodiments of this example, a first transmission mechanism is provided between the drive element 205 and the bracket 301. The first transmission mechanism includes a first sprocket 10, a second sprocket 11, a first rotating shaft 12, an eccentric wheel 13, a transmission rod 14, and an eccentric block 15. The first sprocket 10 is disposed at the output end of the drive element 205, the first rotating shaft 12 is disposed on the mounting base 201, the second sprocket 11 is rotatably disposed on the first rotating shaft 12, the eccentric wheel 13 is disposed on the first rotating shaft 12, one end of the transmission rod 14 is connected to the eccentric wheel 13, the eccentric block 15 is connected to the bracket 301 through the second rotating shaft, and the other end of the transmission rod 14 is connected to the eccentric block 15.
[0036] In this embodiment, the first transmission mechanism is used to convert and transmit the output power of the drive element 205 to the metering pump 202, so as to provide continuous metering power to the metering pump 202, thereby facilitating continuous packaging operation of the packaging machine body 1 without stopping, and greatly improving production efficiency. Specifically, the first sprocket 10 rotates coaxially with the output shaft of the drive element 205. The first sprocket 10 and the second sprocket 11 are connected by a chain (not shown in the figure). Under the drive of the first sprocket 10, the power source of the drive element 205 is output to the second sprocket 11, thereby driving the eccentric wheel 13 to rotate. The eccentric wheel 13 transmits power to the transmission rod 14 and the eccentric block 15 in sequence. Through the eccentric wheel 13 in the first transmission mechanism, the continuous rotational motion can be converted into periodic reciprocating motion through its asymmetrical geometric structure, that is, the axis is off-center. The connecting rod 203 is driven by the swing bracket 301 to realize the reciprocating motion of the piston in the metering pump 202.
[0037] Please refer to Figures 1-4In some embodiments of this example, the mounting base 201 is provided with a second transmission mechanism for driving the metering pump 202. The second transmission mechanism includes a first gear 16 connected to the metering pump 202, a second gear 17 rotatably mounted on the mounting base 201, and a third sprocket 18 mounted on the first sprocket 10. The first gear 16 and the second gear 17 mesh, the first sprocket 10 and the third sprocket 18 rotate coaxially, and a fourth sprocket 19 is mounted on the second gear 17. The third sprocket 18 and the fourth sprocket 19 are driven by a chain.
[0038] In this embodiment, the second transmission mechanism is used to transmit the power output by the drive element 205 to the metering pump 202. This allows multiple components to utilize a single power source simultaneously, effectively saving materials and facilitating metering, thus improving the synergistic effect of each metering component. Specifically, the first gear 16 and the second gear 17 mesh with each other, driving the third sprocket 18 to transmit the power from the drive element 205 to the fourth sprocket 19. The rotation of the fourth sprocket 19 drives the rotation of the second gear 17, which in turn drives the rotation of the first gear 16, thereby driving the movement of the metering pump 202.
[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
