DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0029] Embodiment:

[0030] Please refer to Figure 1 - Figure 4 A feeding device for packaging machine in the embodiment, including; workbench 1, fixedly connected to the surface of the stock bin 2 of workbench 1,

[0031] Power structure 3, including fixedly connected to the surface of the stock bin 2 support rod 4, fixedly connected to the surface of the support rod 4 power assembly 5;

Transmission structure 6 efficiently transmits power to beating assembly 10, destroys the material rack structure, and ensures that the material is smoothly discharged.

[0033] Wherein, the stock bin 2 is composed of straight cylinder 15 and discharge cone 16, the straight cylinder 15 is fixedly connected to the surface of the discharge cone 16, and the bottom of the discharge cone 16 is fixedly connected with blanking cylinder 27;

[0034] At this time, the power assembly 5 comprises a hollow cylinder 11 fixedly connected to the surface of the support rod 4, a rotating shaft 12 rotatably connected to the inside of the hollow cylinder 11, a anti-off plate 14 fixedly connected to one end of the rotating shaft 12, and one end of the connecting rod 7 fixedly connected to the surface of the anti-off plate 14;

[0035] The surface of the rotating shaft 12 is fixedly connected with three spiral vanes 13 arranged in a circle, and the diameter of the circle formed by the rotation of the spiral vanes 13 is smaller than the diameter of the discharging cylinder 27. The three spiral vanes 13 are arranged in a circle, and a material guide channel is formed when the spiral vanes 13 rotate, which not only accelerates the discharging but also avoids the material from being stuck; the diameter of the spiral vanes 13 is smaller than the diameter of the discharging cylinder 27, so that the spiral vanes 13 do not interfere with the discharging port during rotation, and the smoothness of discharging is improved.

[0036] The hitting assembly 10 comprises a first fixed ring 17 fixedly connected to the surface of the straight cylinder 15, a second fixed ring 18 fixedly connected to the surface of the discharging cone 16, a first groove 19 formed on the second fixed ring 18, and a second groove 22 formed on the first fixed ring 17.

[0037] The surface of the first groove 19 is rotatably connected with a transmission plate 20, the surface of the transmission plate 20 is linearly arranged with a hitting block 21, the surface of the transmission plate 20 is fixedly connected with a connecting block 24, and the surface of the connecting block 24 is fixedly connected with a convex block 25.

[0038] The surface of the connecting block 24 is provided with a hidden groove 26, the surface of the hidden groove 26 is fixedly connected with a spring 23, one end of the spring 23 is fixedly connected to the surface of the second groove 22; the hitting block 21 arranged linearly on the surface of the transmission plate 20 is reset by the spring 23 to realize high-frequency vibration, and directly acts on the surface of the discharging cone 16 to break the bridging structure of the material.

[0039] The surface of the workbench 1 is fixedly connected with a feeding frame 28, the surface of the workbench 1 is fixedly connected with a clamping plate 29, and the surface of the clamping plate 29 is fixedly connected with a clamping block 30. The clamping plate 29 and the clamping block 30 fix the position of the container, prevent the container from deviating during filling, ensure that the material falls accurately into the packaging station, and improve the stability of packaging.

[0040] The working principle of the above embodiment is as follows: when the material falls, the gravity drives the spiral vanes 13 to rotate, the vanes drive the anti-off plate 14 and the connecting rod 7 to rotate through the rotating shaft 12, the vertical vertical rod 8 and the extrusion block 9 at the end of the connecting rod 7 periodically push the convex block 25 on the transmission plate 20, the spring 23 is reset to make the transmission plate 20 drive the hitting block 21 to vibrate the discharging cone 16 at high frequency, and the material bridging is broken at the same time, and the spiral vanes 13 accelerate the material to pass through the discharging cylinder 27, realizing self-driven anti-blocking and discharging efficiency.

[0041] In use, the material is poured from the top of the bin 2 and flows along the straight cylinder 15 to the discharge cone 16 under the action of gravity. When the material enters the discharge port of the discharge cylinder 27, the falling impact force of the material directly acts on the surface of the spiral fan blade 13, pushing the fan blade to rotate around the rotating shaft 12. At this time, the rotating motion of the spiral fan blade 13 is transmitted to the anti-off plate 14 through the rotating shaft 12, driving the connecting rod 7 and the vertical shaft 8 to rotate synchronously. The extrusion block 9 at the end of the vertical shaft 8 makes a circular motion, periodically extruding the protrusions 25 on the surface of the transmission plate 20, forcing the transmission plate 20 to reciprocate around the connecting point of the first fixed ring 17 and the second fixed ring 18. When the transmission plate 20 swings, the line array arranged on the surface of the striking block 21 continuously hits the outer wall of the discharge cone 16, generating vibration and breaking the friction and adhesion between the material particles, preventing arching. Using the gravity of the material itself as a power source, no additional energy input is required, saving energy and reducing energy consumption. The striking block 21 continuously hits the discharge cone 16, effectively breaking the interaction between the material particles and ensuring smooth material falling. At the same time, the spring 23 exerts a reverse pulling force on the connecting block 24 through the hidden slot 26, ensuring that the transmission plate 20 quickly resets after being struck, forming a continuous and regular vibration cycle.

[0042] The rotation of the spiral fan blade 13 not only provides power for the arch breaking mechanism, but also generates an axial thrust on the material itself, accelerating the material through the discharge cylinder 27 and avoiding accumulation. Since the diameter of the fan blade is smaller than the discharge port, it will not rub against the inner wall of the bin 2 during rotation, ensuring smooth discharge. In addition, the support rod 4 is designed to branch below the discharge port, which can disperse the material flow and reduce local pressure concentration, further reducing the risk of arching.

[0043] The installation method, connection method or setting method disclosed in the embodiment are common mechanical connection methods, as long as they can achieve the beneficial effects, and can be implemented. Therefore, the specific structure, composition and working principle of the embodiment will not be described in detail.
