    Compared with the prior art, the present invention has the advantages that through the upper regulating plate, the lower regulating plate, the feeding barrel. the telescopic sleeve and the floating ball which work with each other, the feeding barrel is separated from the tank body, thus mitigating the influence of the vibrator on the weight scale and improving the weighing accuracy. Brief Description of the Drawings FIG.1 is a section view of the feeding device for food packaging of an embodiment of the present invention.
    I-lower regulating plate, 2-upper regulating plate, 3-feeding barrel, 4-telescopic sleeve, 5-air supply system, 6-floating ball, 7-guiding axle, 8-first floating hole, 9-second floating hole, 10-tank body.
    Detailed Description of the Preferred Embodiments The feeding device for food packaging of the present invention will be described in more detail in combination with the schematic diagram where a preferred embodiment of the present invention is indicated. It should be understood that those skilled in the art can modify the present invention described herein while still achieve the advantages of the present invention. Therefore, the following description should be understood as a broad knowledge of those skilled in the art and does not constitute a limitation of the present invention.
    As shown in FIG.1, a feeding device for food packaging comprises a tank body 10, a feeding barrel 3, a telescopic sleeve 4, an upper regulating plate 2, a lower regulating plate 1. floating balls 6, an air supply system 5, a vibrator and a weight scale.
    The lower regulating plate 1, the upper regulating plate 2 and the feeding barrel 3 are successively arranged from the top of the tank body 10 from bottom to top; the lower regulating plate 1, the upper regulating plate 2 and the feeding barrel 3 are communicated with the inner cavity of the tank body 10.
    The lower regulating plate 1 is fixed to the feeding barrel 3: the upper regulating plate 2 is fixed to the lower regulating plate 1; a first floating hole 8 is arranged in the lower regulating plate 1; an air passage is arranged in the lower regulating plate 1: the air passage is communicated with the first floating hole 8: the air supply svstem 5 is fixed to the lower regulating plate 1 and communicated with the air passage; the floating ball 6 is arranged in the first floating hole 8.
    A second floating hole 9 communicated with the first floating hole 8 is arranged in the upper regulating plate 2; the diameter of the second floating hole 9 is smaller than that of the floating ball 6; a guiding axle 7 is arranged on the upper regulating plate 2; the shoulder bushing of the feeding barrel 3 is installed to the guiding axle 7.
    The upper end of the telescopic sleeve 4 is bonded to the inner wall of the feeding barrel 3, and the lower end is bonded to the inner wall of the feeding barrel 3. The weight scale is fixed inside the feeding barrel 3 and directly faces a feed inlet of the tank body 10; the vibrator is fixed to the outer wall of the feeding barrel 3. In this embodiment, the floating ball 6 is an elastomer. In this embodiment, the telescopic sleeve 4 comprises a plurality of flexible sleeves; the flexible sleeves are successively connected in the axial direction.
    In this embodiment, the device further comprises a pushing mechanism; the pushing mechanism pushes food on the weight scale into a feed outlet of the feeding barrel 3. The pushing mechanism comprises a push plate arranged in the tank body 10 and an outer cylinder fixedly arranged at the tank body 10, wherein, a piston rod of the cylinder passes through the tank body 10 and is fixed to the push plate, and the cylinder can drive the push plate to move evenly towards or away from the direction of the feed outlet.
    In this embodiment, both the vibrator and the air supply system 5 are connected with a control unit signal.
    The working principle of the present invention is that when in use. the food enters from an upper port of the telescopic sleeve 4. and smoothly falls on the weight scale for weighing under the action of the vibrator; meanwhile, the air in the air supply system 5 is injected at high pressure at the first floating hole 8 via the air passage to eject the floating ball 6 from the first floating hole 8 to the second floating hole 9. the floating ball 6 is stuck in the first floating hole 8, the feeding barrel 3 is jacked up, the feeding barrel 3 and the tank body 10 are separated, thus reducing the influence of the vibration of the feeding barrel 3 on the tank body 10; when the weight measured by the weight scale reaches a set value (in the actual product, the set value is a range), the cylinder works to push the push plate to push the product falling on the weight scale out of the tank body 10 through the feed outlet, thus stabilizing the weight of the food in each packaging bag within a range of values.
    The description above is the preferred embodiment of the invention only, and has no limit to the invention.
