[0001] This utility model relates to the field of grain feeding and packaging technology, and in particular to an automatic quantitative grain packaging machine. Background Technology
[0002] Packaging machines are machines that package products, serving to protect and enhance their appearance. When packaging grains, a specific quantity of material needs to be fed into the packaging container.
[0003] Existing feeding and packaging machines typically feed grains at a fixed capacity. However, when packaging smaller grains such as corn kernels, the target customers vary. For example, corn kernels are used for homemade popcorn, and the capacity of disposable bags is relatively small, requiring only simple equipment for quantitative packaging. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic quantitative packaging machine for grain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic quantitative packaging machine for grain includes a storage cylinder, an mounting plate fixedly connected to the upper surface of the storage cylinder, an electric telescopic rod fixedly connected to the upper surface of the mounting plate, a J-shaped plate fixedly connected to the inner wall of the storage cylinder, and a quantitative feeding mechanism sleeved on the inner wall of the storage cylinder.
[0007] The quantitative feeding mechanism includes a ball head sleeved on the inner wall of the storage cylinder, a discharge telescopic cylinder fixedly connected to the inner wall of the ball head, a receiving cylinder fixedly connected to the surface of the discharge telescopic cylinder, a T-shaped groove opened on the upper surface of the J-shaped plate, a support plate fixedly connected to the lower surface of the receiving cylinder, a convex shaft rotatably connected to the inner wall of the support plate, and the convex shaft installed inside the T-shaped groove.
[0008] An electric lead screw is rotatably connected to the inner wall of the receiving cylinder, and a V-shaped plate is slidably connected to the surface of the receiving cylinder. The electric lead screw is rotatably connected to the inner wall of the V-shaped plate. A first telescopic cylinder is fixedly connected to the output end of the electric telescopic rod. A connecting plate is fixedly connected to one side of the receiving cylinder, and a turntable is rotatably connected to the inner wall of the connecting plate. The surface of the turntable is fixedly connected to the bottom end of the first telescopic cylinder.
[0009] Preferably, a triangular plate is fixedly connected to the surface of the first telescopic cylinder, and a first connecting rod is slidably connected to the inner wall of the storage cylinder, with one side of the first connecting rod slidably connected to the surface of the triangular plate.
[0010] Preferably, an L-shaped connecting rod is slidably connected to the inner wall of the storage cylinder, and a push plate is fixedly connected to one side of the L-shaped connecting rod.
[0011] Preferably, the lower surface of the first connecting rod is rotatably connected to a second telescopic cylinder, and the lower surface of the second telescopic cylinder is rotatably connected to the upper surface of the L-shaped connecting rod.
[0012] Preferably, a feeder is fixedly connected to the surface of the storage cylinder.
[0013] Preferably, a pair of push plates are installed on both sides of the J-shaped plate.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The output end of the electric telescopic rod drives the triangular plate and the turntable to move together, so that the support plate and the cam shaft connected to the receiving cylinder move in the T-slot. When the receiving cylinder moves to the curved side of the J-shaped plate, the angle of the receiving cylinder tilts, and its highest surface overflows the highest surface of the grain, shoveling the grain in the storage cylinder into the receiving cylinder. At this time, the stretching discharge telescopic cylinder becomes longer, and the grain in the receiving cylinder is automatically discharged for packaging under the tilting action of the discharge telescopic cylinder. The electric screw rotates and drives a pair of V-shaped plates to move closer or further apart, which allows the space inside the V-shaped plates to be adjusted, realizing the control of grain discharge during discharge.
[0016] 2. When a pair of triangular plates move, the first connecting rod slides on the surface of the triangular plates. At this time, the second telescopic cylinder rotates under force and automatically adjusts its length to adapt. The rotation of the second telescopic cylinder drives the L-shaped connecting rod to slide, so that a pair of push plates move closer to each other and push the grain above the J-shaped plate, making it easy for the receiving cylinder to scoop up the grain.

A ball head 6 is provided to facilitate free rotation and adjustment within the storage cylinder 1. A discharge telescopic cylinder 7 is provided to adapt to the movement of the receiving cylinder 8 for length adjustment. A T-groove 16 is provided to guide and support the movement of the convex shaft 18. A support plate 17 is provided to maintain stable support for the receiving cylinder 8. An electric lead screw 9 is provided to adjust the position of the V-shaped plate 10, thereby changing the internal space of the receiving cylinder 8 and achieving quantitative adjustment of grain capacity. The first telescopic cylinder 14 is provided to adapt to changes in the height of the receiving cylinder 8. A connecting plate 12 and a turntable 11 are provided to maintain the movement connection of the receiving cylinder 8.
[0027] A triangular plate 15 is fixedly connected to the surface of the first telescopic cylinder 14, and a first connecting rod 19 is slidably connected to the inner wall of the storage cylinder 1. One side of the first connecting rod 19 is slidably connected to the surface of the triangular plate 15.
[0028] In this utility model, a triangular plate 15 is set, which moves with the first telescopic cylinder 14 to drive the first connecting rod 19 to slide and adjust its position.
[0029] An L-shaped connecting rod 21 is slidably connected to the inner wall of the storage cylinder 1, and a push plate 13 is fixedly connected to one side of the L-shaped connecting rod 21.
[0030] In this utility model, by setting push plates 13, a pair of push plates 13 approach each other to push the grain in the storage cylinder 1 to the top of the J-shaped plate 5, so that the receiving cylinder 8 can easily scoop it up.
[0031] The lower surface of the first connecting rod 19 is rotatably connected to the second telescopic cylinder 20, and the lower surface of the second telescopic cylinder 20 is rotatably connected to the upper surface of the L-shaped connecting rod 21.
[0032] In this utility model, by setting a second telescopic cylinder 20, the movement of the first connecting rod 19 drives the second telescopic cylinder 20 to rotate, and its length is adjusted accordingly, and the L-shaped connecting rod 21 is driven to slide.
[0033] A feeder 2 is fixedly connected to the surface of the storage cylinder 1.
[0034] In this utility model, by setting up a feeder 2, the feeder 2 continuously feeds the grain to ensure that the grain in the storage cylinder 1 is above the height of the J-shaped plate 5, and to ensure that the receiving cylinder 8 accurately picks up the grain.

[0037] Working principle: The feeder 2 starts to continuously feed material into the storage cylinder 1. The electric telescopic rod 4 is activated, and its output end drives the triangular plate 15 and the turntable 11 to move together. The movement of the turntable 11, through the connecting plate 12, causes the receiving cylinder 8 to be stressed, resulting in the support plate 17 and the convex shaft 18 connected to the receiving cylinder 8 moving within the T-slot 16. When the receiving cylinder 8 moves to the curved side of the J-shaped plate 5, the angle of the receiving cylinder 8 tilts, and its highest surface overflows the highest surface of the grain, shoveling the grain from the storage cylinder 1 into the receiving cylinder 8. At this time, the extended discharge telescopic cylinder 7 becomes longer, and the grain in the receiving cylinder 8 is discharged and packaged under the tilting action of the discharge telescopic cylinder 7. When it is necessary to adjust the distance between a pair of V-shaped plates 10 to quantitatively control the packaging volume... When measuring, the electric lead screw 9 is activated. The rotation of the electric lead screw 9 drives a pair of V-shaped plates 10 to move closer or further apart, thus adjusting the space within the V-shaped plates 10. During discharge, the grain feeding is controlled. When the first telescopic cylinder 14 moves, it drives a pair of triangular plates 15 to move, causing the first connecting rod 19 to slide on the surface of the triangular plates 15. At this time, the second telescopic cylinder 20 is rotated under force, automatically adjusting its length to adapt. The rotation of the second telescopic cylinder 20 drives the L-shaped connecting rod 21 to slide, causing a pair of push plates 13 to move closer together, pushing the grain above the J-shaped plate 5, making it convenient for the receiving cylinder 8 to scoop up the grain. With the above structure, smaller grain packages can be fed, and the feeding capacity can be adjusted during feeding and packaging.
