Description

Technical Field

[0001] This invention relates to the field of packing device technology, specifically to an automatic packing device for uniform feeding in a mixer. Background Technology

[0002] A plastic mixer is a mixing device specifically designed for plastic raw materials (such as granules, powders, recycled materials, etc.). It belongs to a sub-field of mixers. Its core function is to achieve uniform mixing of plastic raw materials through stirring, shearing, heating, etc. It may also take into account additional functions such as drying, coloring, and modification. The filling device is responsible for accurately and evenly conveying the raw materials to be mixed from the storage container to the feed port of the mixer.

[0003] In the prior art, such as the filling device of an infant milk powder filling machine with publication number CN219172708U, the milk powder is fed from the storage bin to the discharge pipe through an anti-blocking mechanism, which effectively avoids the accumulation and blockage of milk powder and improves work efficiency. Through a rotating mechanism, the milk powder is poured into the powder can along the circumference, making the milk powder in the powder can more uniform and achieving the ideal effect.

[0004] To address the issue of existing equipment easily causing outlet blockage and affecting filling speed during the filling process, an anti-blocking mechanism was adopted to feed milk powder from the storage silo to the outlet pipe. However, in actual use, when processing high-viscosity or high-density materials, the flowability is poor, and it is easy to accumulate or bridge at the feed inlet, resulting in interruption of feeding. It is difficult to achieve efficient feeding by relying solely on the gravity of the material. Moreover, the feeding speed of traditional packing devices is adjusted by the valve opening, which makes it even more difficult to fill the material evenly in the bridging state, affecting production efficiency.

[0005] Therefore, this invention proposes an automatic filling device for uniform feeding in a mixer to solve the problem that existing equipment is prone to accumulating or bridging at the feed inlet and is difficult to fill uniformly when processing high-viscosity or high-density materials.

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1-21This invention provides a technical solution: an automatic filling device for uniform feeding in a mixer, comprising a mixer body 1 and a filling cylinder 2. A housing 11 is fixedly installed on one side of the mixer body 1, and an annular base 12 is fixedly installed on the upper surface of the housing 11. The filling cylinder 2 is fixedly connected to the upper end of the annular base 12. A feed pipe 3 is connected through the filling cylinder 2 near the side of the mixer body 1. A connecting pipe 31 extending to the top of the mixer body 1 is fixedly and sealed at the lower end of the feed pipe 3. It should be noted that an electric telescopic rod is fixedly installed at one end of the feed pipe 3, and an opening and closing plate is connected to the output end of the electric telescopic rod. The opening and closing of the connecting pipe 31 is achieved by the extension and retraction of the electric telescopic rod. The filling material; a filling cylinder cover 21 is movably installed at the upper end of the filling cylinder 2, and a conical filling chamber 22 is fixedly connected to the lower end of the filling cylinder cover 21. A connecting plate 23 is fixedly connected to the lower end of the conical filling chamber 22, and a rotating material distribution mechanism is provided at the lower end of the connecting plate 23. The rotating material distribution mechanism includes a feeding disc 24, a material distribution port 240 is opened on the upper side of the feeding disc 24, the feeding disc 24 is rotatably installed on the lower inner wall of the filling cylinder 2, a central cone seat 25 is fixedly installed at the center of the feeding disc 24, and a limit component is rotatably connected to the lower end of the feeding disc 24; and the central cone seat 25 is fixedly installed on the inner center of the dividing vertical plate 241, and a triangular plate 253 is fixedly embedded on the outer ring surface of the central cone seat 25. A support frame 252 is fixedly connected to the inner side of the casing 11. An inserting ring plate 251 is fixedly connected to the other end of the support frame 252. The inserting ring plate 251 is bolted to the inner upper end of the threaded sleeve 14. The lower surface of the inserting ring plate 251 is movably engaged with the upper end of the dust collection duct 15. A cleaning brush 2411 is fixedly installed on the side of the partition vertical plate 241 near the side wall of the packing cylinder 2, and the outer surface of the cleaning brush 2411 is movably in contact with the inner side wall of the packing cylinder 2. A threaded sleeve 14 is threadedly connected to the inner lower end of the horizontal circular plate 242. A drive assembly 13 is provided on the outer lower end of the threaded sleeve 14. The drive assembly 13 includes a motor 131, which is fixedly installed on the inner top surface of the casing 11. A motor 131 is fixedly connected to the output shaft of component 13. A drive gear 132 is fixedly installed on the outer surface of the motor 131. A driven gear ring 133 meshes and rotates on the outer surface of the drive gear 132. The inner surface of the center of the driven gear ring 133 is fixedly connected to the outer surface of the threaded sleeve 14. A dust collection duct 15 is rotatably connected to the inner surface of the threaded sleeve 14. A fan is installed at the bottom end of the dust collection duct 15. A dust collection assembly is installed on the inner side of the dust collection duct 15. The dust collection assembly includes a conical filter cover 16. The conical filter cover 16 is movably snapped onto the inner surface of the dust collection duct 15. A dust retention baffle 161 is fixedly installed on the outer surface of the dust retention baffle 161. The dust retention baffles 161 are distributed in a ring array outside the conical filter cover 16.By combining the dust collection component with the dust storage duct 15, the dust particles separated from the plastic granules can be prevented from being discharged directly. The conical filter cover 16 is used to block the dust particles, and with the addition of the dust retention baffle 161, the dust particles can be effectively retained, avoiding the blockage of the conical filter cover 16. In this embodiment, before using the filling device, a dust collection component is first installed inside the dust storage duct 15, and the lower end of the dust storage duct 15 extends to the top of the inner side of the casing 11. The feeding disc 24 is placed inside the filling cylinder 2 and threadedly connected to the upper part of the threaded sleeve 14 to achieve quick assembly of the feeding disc 24. Then, the filling cylinder cover 21 is placed on the upper end of the filling cylinder 2 and locked. After the assembly is completed, the material is poured out through the discharge port at the upper end of the filling cylinder cover 21. The material enters the conical filling chamber 22 for temporary storage. When the equipment is started, the drive component 13 runs as a whole, driving the feeding disc 24 to rotate as a whole. The material enters the distribution port 240 from the bottom end of the conical filling chamber 22. Under the action of rotation, the feeding disc 24 generates centrifugal force, which is converted into radial thrust. This causes the material to be thrown to the input port of the feed pipe 3 and finally enters the mixer body 1 through the connecting pipe 31 for mixing. It is worth noting that the central cone seat 25 and multiple sets of triangular plates 253 combine to form a conical structure, which guides the incoming material while the particulate dust in the granular material enters the dust storage duct 15 through the evenly spaced sieve holes on the triangular plates 253, and is retained by the conical filter cover 16 and the dust retention baffle 161. It should also be noted that the interlocking ring plate 251 and support frame 252 connected to the inner side of the central cone seat 25 can limit the feeding disc 24 to the top of the dust storage duct 15 during assembly, and can provide support for the central cone seat 25 and the triangular plates 253, ensuring the overall structural strength of the central cone seat 25 and extending its service life.

[0022] Example 2, see attached document Figure 1-21 Based on Example 1, in order to achieve effective separation of materials and particulate dust on the triangular plate 253 and avoid clogging of the sieve holes on the surface of the triangular plate 253: A recessed groove 2530 is formed on the inner wall of the center of the triangular plate 253. A retaining strip 2532 is snapped onto the inner surface of the recessed groove 2530. A support frame recess 25320 is formed on the upper inner wall of the retaining strip 2532. The inner wall of the support frame recess 25320 is fitted and snapped onto the outer surface of the end of the support frame 252 away from the retaining ring plate 251. Side panels 2531 are fixedly installed on both sides of the triangular plate 253. Protruding cones are evenly distributed on the outer surface of the triangular plate 253. The design can block plastic particles. The even distribution of the protruding cones prevents the plastic particles from completely contacting the outer wall of the triangular plate 253, thus avoiding clogging of the sieve holes on the surface of the triangular plate 253. A receiving groove 2520 is formed on the inner surface of the support frame 252. A prying element and a triggering element are provided inside the receiving groove 2520. The prying element includes a swing rod 2521, which is rotatably mounted inside the receiving groove 2520 via a pin. The triggering element includes a pressing block 25201. The inner surface of 1 is in contact with the upper end of the swing rod 2521. The other end of the swing rod 2521 is fixedly connected to a triangular wedge 1 2522. The outer surface of the triangular wedge 1 2522 is in contact with a triangular wedge 2523. The other end of the triangular wedge 2523 is fixedly connected to a striking frame 2524. The outer surface of the striking frame 2524 is slidably connected to the inner wall of the support frame 252, and the end of the striking frame 2524 away from the triangular wedge 2523 is in contact with the inner surface of the mounting strip 2532. A sliding opening 25200 is provided through the upper end of the groove 2520. The inner surface of the sliding opening 25200 is slidably connected to the outer surface of the extrusion block 25201. Sliding grooves are provided on the inner walls of both sides of the sliding opening 25200. A connecting block 25202 is slidably connected to the inner surface of the sliding groove. The connecting block 25202 is fixedly installed on both sides of the extrusion block 25201. An abutment wire 25203 is fixedly connected to the inner surface of the connecting block 25202. The other end of the abutment wire 25203 is fixedly connected to the inner wall of the sliding groove. In this embodiment, during the material filling process, the plastic particles fall to the outer surface of the central cone seat 25 and the triangular plate 253. Some particles are thrown to both sides under the action of centrifugal force and gravity, while some particles will mix with the surface of the extrusion block 25201. At this time, the extrusion block 25201 moves inward and squeezes the upper end of the swing rod 2521. At this time, one end of the swing rod 2521 is pressed down by force, and according to the lever principle, the other end of the swing rod 2521 will swing upward. Refer to Figure 16-17As shown, at this time, the first triangular wedge 2522 and the second triangular wedge 2523 are engaged. The second triangular wedge 2523 is pushed outward by the first triangular wedge 2522, and the sleeve spring 25241 is compressed and deformed. At the same time, the end of the striking frame 2524 away from the second triangular wedge 2523 strikes the inner surface of the triangular plate 253. This helps the particles and dust on the triangular plate 253 to fall off, avoiding the blockage of the sieve holes of the triangular plate 253 over a long period of time. It should be further noted that the support frame 252 here serves as a support for the triangular plate 253, can accommodate the swing rod 2521 and the first triangular wedge 2522, and can also provide a limiting function for the striking frame 2524, achieving the effect of "one frame for multiple uses".

[0023] Example 3, refer to Appendix Figure 1-21 Based on Example 2, in order to achieve stability when the feeding disc 24 rotates and distributes the material: The feeding disc 24 consists of vertical dividing plates 241 and horizontal circular plates 242. Two sets of horizontal circular plates 242 are integrally formed with six sets of vertical dividing plates 241. The limiting assembly includes a limiting ring plate 26, which is fixedly installed on the bottom surface of the inner cavity of the packing cylinder 2. An air distribution chamber 260 is provided within the inner cavity of the limiting ring plate 26. Air guide grooves 2410 are provided on the inner walls of the vertical dividing plates 241, and the air distribution chamber 260 is connected to the input end of the air guide groove 2410. The lower part of the horizontal circular plate 242... An annular groove 2420 is provided on the inner wall of the end. The inner surface of the annular groove 2420 is rotatably connected to the upper outer surface of the limiting ring plate 26. A gas inlet pipe 261 is connected through one side of the inner wall of the limiting ring plate 26 and extends to the outside of the packing cylinder 2. A rotating impeller 262 is rotatably connected to the inner cavity of the gas distribution chamber 260 through a bearing. A guide vane 2621 is uniformly added to the upper surface of the rotating impeller 262. A turbulence protrusion 26211 is fixedly added to one side of the curved surface of the guide vane 2621. In this embodiment, when the feeding disc 24 is installed as a whole, the annular groove 2420 on the bottom side of the annular groove 2420 is adapted to the upper end of the limiting ring plate 26. The two cooperate with each other to ensure the stability of the feeding disc 24 when rotating and distributing material. At the same time, the gas inlet pipe 261 connected to one side of the limiting ring plate 26 is connected to an external gas source to inject high-pressure gas into the inner side of the air distribution chamber 260. At this time, the high-pressure gas will blow the rotating impeller 262 to perform the following: Rotation allows the gas to be more evenly distributed inside the air distribution chamber 260 and finally discharged through the air guide groove 2410. High-pressure gas enters the spacer plate 241 and the central cone seat 25 from the air delivery end of the air guide groove 2410. This can blow away the dust accumulated on the triangular plate 253 to avoid the sticking and the inability to discharge the material in time, and can also supply gas into the inside of the packing cylinder 2 to achieve auxiliary drying of the material. This can avoid the sticking of the granular material and the blockage of the discharge.

[0024] Example 4, see attached document Figure 1-21 Based on Example 3, in order to achieve a continuous supply of fabric at 240 openings: A support rib plate 221 is fixedly installed at the lower end of the conical packing bin 22. Multiple sets of support rib plates 221 are arranged in a circular array about the central axis of the conical packing bin 22. The support rib plate 221 is integrally formed from a triangular plate and a strip plate. A support ring 222 is fixedly connected to the lower end of the strip plate, and the lower end of the support ring 222 is fixedly connected to the upper surface of the connecting plate 23. An auxiliary contact assembly is provided between the upper side of the feeding disc 24 and the lower side of the conical packing bin 22. The auxiliary contact assembly includes a corrugated ring 231 and a contact rod 232. The corrugated ring 231 is fixedly installed on the upper surface of the feeding disc 24, and the outer surface of the contact rod 232 is slidably connected to the inner wall of the strip plate. Both ends of the rod 232 are respectively provided with arc-shaped contact ends. The lower outer surface of the rod 232 is movably connected to the upper surface of the wave ring 231. A spring 233 is slidably sleeved on the outer surface of the rod 232. The lower end of the spring 233 is fixedly connected to the upper inner wall of the strip plate. The other end of the spring 233 is fixedly connected to a positioning plate 234. The positioning plate 234 is fixedly installed on the outside of the rod 232. The upper outer surface of the rod 232 is slidably connected to the inner wall of the conical packing bin 22. The end of the rod 232 away from the wave ring 231 movably abuts against an elastic shaking block 220. The elastic shaking block 220 is fixedly installed on the inner surface of the conical packing bin 22. In this embodiment, refer to Figure 6 As shown, during the rotation of the feeding disc 24 and the distribution of material, the corrugated ring 231 connected to its upper end rotates synchronously. At this time, the contacting rod 232, which is in contact with the corrugated surface of the upper side of the corrugated ring 231, will continuously rise and fall. During the rising process of the contacting rod 232, the spring 233 will undergo tensile deformation and abut against the inner side of the elastic shaking block 220. At this time, the elastic shaking block 220 will deform and can assist in pushing the material inside the conical filling bin 22. When the contacting rod 232 reaches the corrugated ring 231, the material will be distributed in a continuous manner. When the wavy surface of ring 231 is at its lowest position, the abutting rod 232 returns to its initial position under the reverse elastic force of spring 233. At this time, the elastic shaking block 220 will not be abutted, thus realizing the intermittent pushing of material inside the conical packing bin 22 and further avoiding blockage, bridging and other phenomena. It should be noted that the supporting rib plate 221 here is integrally formed by a triangular plate and a strip plate, which can not only support the outer wall of the conical packing bin 22 and strengthen the structural strength, but also provide a limiting effect for the auxiliary abutting component.

[0025] Example 5, see attached document Figure 1-21 Based on Example 4, in order to further improve the material falling efficiency within the conical packing bin 22: A material control assembly is provided at the upper end of the central cone seat 25. The material control assembly includes a threaded column 27. The lower outer surface of the threaded column 27 is threadedly connected to the inner wall of the top end of the central cone seat 25. A spiral blade 271 is fixedly connected to the upper end of the threaded column 27. A stirring arm 272 is fixedly connected to the lower outer surface of the threaded column 27. The stirring arm 272 has a hollow tubular structure. A spring wire 2721 is fixedly connected to the inner surface of the stirring arm 272. A telescopic arm 273 is fixedly connected to the other end of the spring wire 2721. The outer surface of the telescopic arm 273 is slidably connected to the inner wall of the stirring arm 272. A contact ball 2731 is threadedly connected to the other end of the telescopic arm 273 away from the spring wire 2721. In this embodiment, a threaded post 27 is threadedly installed at the top of the central cone seat 25. When the central cone seat 25 rotates with the feeding disc 24, the threaded post 27 drives the spiral blade 271 to rotate synchronously, conveying the material in a spiral manner. Through the connection of the stirring arm 272 and the telescopic arm 273 at the feed port of the conical packing bin 22, the material at the output port can be stirred. Under the centrifugal force, the telescopic arm 273 can extend and retract inside the stirring arm 272, thereby causing the contact ball 2731 to assist in striking the side wall of the conical packing bin 22, thus accelerating the falling of the material and avoiding blockage or bridging.

[0026] The working principle and usage process of this invention are as follows: In actual use, firstly, a dust collection component is installed inside the dust storage duct 15. The feeding disc 24 is placed inside the packing cylinder 2 and threadedly connected to the upper part of the threaded sleeve 14. The packing cylinder cover 21 is then covered and locked to complete the assembly. Then, material is poured into the conical packing bin 22 from the discharge port at the upper end of the packing cylinder cover 21. The equipment is started to make the drive component 13 run and drive the feeding disc 24 to rotate. The material enters the distribution port 240 from the bottom end of the conical packing bin 22 and is thrown to the input port of the feed pipe 3 under the centrifugal force generated by the rotation. It then enters the mixing machine body 1 through the connecting pipe 31 for mixing. At this time, the conical structure formed by the central cone seat 25 and multiple sets of triangular plates 253 guides the material flow. The particulate dust enters the dust storage duct 15 through the sieve holes of the triangular plates 253 and is trapped by the conical filter cover 16 and the dust trapping baffle 161. Dust is retained; subsequently, when the material falls to the outer surface of the triangular plate 253, some particles act on the extrusion block 25201, causing the swing rod 2521 to swing, which drives the striking frame 2524 to strike the inner surface of the triangular plate 253, assisting the falling of particle dust; at the same time, high-pressure gas is input through the gas inlet pipe 261 to blow the rotating impeller 262 to rotate, so that the gas is evenly distributed and discharged from the air guide groove 2410, blowing the dust accumulated on the triangular plate 253, assisting the material to dry and be discharged; furthermore, when the feeding disc 24 rotates, the upper wave ring 231 rotates, causing the contact rod 232 to rise and fall. When rising, the spring 233 abuts against the elastic shaking block 220 to assist in pushing the material, realizing intermittent pushing; a material control component is installed at the top of the central cone seat 25, which spirally conveys the material when rotating, while the telescopic arm 273 extends and retracts, causing the contact ball 2731 to strike the side wall of the conical filling bin 22, accelerating the falling of the material.
