Description

Technical Field

[0001] This utility model relates to the field of food packaging equipment technology, specifically to a feeding device for a food deoxidizer packaging machine. Background Technology

[0002] In the production of food oxygen absorbers, the feeding device of the packaging machine is a key component for ensuring product quality and production efficiency. Currently, the industry commonly uses a rotary turntable feeding structure, which relies primarily on the rotation of the turntable to transfer and feed materials. However, this traditional structure suffers from low feeding accuracy. During the turntable's rotation, material in the measuring cup is easily thrown out from both sides, resulting in an actual feeding weight deviation exceeding ±5%, failing to meet the precision packaging requirements of food oxygen absorbers. Maintenance costs are high; rotating parts wear out quickly, requiring replacement of vulnerable parts 1-2 times per week on average, and residual material on the table needs to be cleaned hourly, severely impacting production efficiency. Adaptability is poor; it cannot achieve differentiated capacity adjustment for two materials, making it difficult to quickly adapt to different specifications of oxygen absorber packaging requirements. The failure rate is high; the rotating structure is complex with many transmission links, resulting in an average of 3-5 mechanical failures per month, causing production interruptions.

[0003] Based on this situation, a feeding device for a food deoxidizer packaging machine is provided, including a mounting base, a linear drive mechanism, a measuring cup assembly, a knob adjustment structure, and a baffle opening and closing structure. The mounting base serves as the overall support foundation and includes a drive mounting platform and a measuring cup fixing platform. The linear drive mechanism includes a drive source, a transmission connecting rod, a linear guide rail, and a slider. The measuring cup assembly includes a measuring cup body, a scale plate, and a feeding push plate. The knob adjustment structure includes a knob and a lead screw transmission assembly. The baffle opening and closing structure includes a drive motor and a baffle. This device controls the size of the feeding port by adjusting the knob and moving the scale plate back and forth. It uses linear drive instead of traditional rotary drive, and features high feeding accuracy, good stability, easy maintenance, and strong adaptability, which can meet the diverse needs of dual-material packaging for food deoxidizers.

The slider 24 is slidably disposed on the linear guide rail 23.

[0034] Specifically, the drive source 21 is a cylinder, and the linear guide rail 23 is parallel to the axis of the cylinder; the linear guide rail 23 is fixed to the drive mounting platform 11 by M4 bolts; the linear guide rail 23 is embedded in the slider 24, and the sliding resistance is <0.5N.

[0035] The measuring cup assembly 30 includes a measuring cup body 31, a scale plate 32, and a feeding pusher plate 33. The measuring cup body 31 is welded and fixed to one side of the measuring cup fixing platform 12. The scale plate 32 is disposed on the inner wall of the bottom of the measuring cup body 31. The feeding pusher plate 33 is connected to the transmission connecting rod 22 by bolts. A feeding port 34 is provided at the bottom of the measuring cup body 31 where it meets the scale plate 32. The surface of the scale plate 32 is provided with linear scales corresponding to the opening size of the feeding port 34.

[0036] Specifically, the scale plate 32, the slider 24 and the drive source 21 are arranged along the length of the measuring cup body 31, the axis of the transmission connecting rod 22 is aligned with the center of the short side of the feeding port 34, the scale plate 32 initially completely covers the feeding port 34, and the sliding stroke of 1mm corresponds to an opening of 1mm.

[0037] The knob adjustment structure 40 includes a knob 41 and a lead screw drive assembly 42. The lead screw drive assembly 42 connects the knob 41 and the scale plate 32. The lead screw drive assembly 42 includes a lead screw 43. One end of the lead screw 43 is coaxially and fixedly connected to the knob shaft of the knob 41 through a coupling.

At this time, the transmission rod 22 moves away from the feeding port 34 of the measuring cup body 31, and the feeding push plate 33 moves with the transmission rod 22. At the same time, the drive motor 51 drives the baffle 52 to move counterclockwise. The needle rotation opens the feeding channel, allowing the food deoxidizer material to fall from the measuring cup body 31 through the adjusted feeding port 34 to the packaging station under gravity. After one feeding cycle, the drive source 21 drives the transmission rod 22 to move in the opposite direction, towards the feeding port 34 of the measuring cup body 31. The feeding push plate 33 moves with the transmission rod 22, while the drive motor 51 drives the baffle 52 to rotate counterclockwise to close the feeding channel and prevent the material from falling further, thus completing one feeding cycle.
