Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PE particle processing equipment, and in particular to a mixing-free feeder. Background Technology
[0002] PE particle processing (such as blown film, injection molding, and extrusion) typically requires continuous operation. Manual feeding can lead to interruptions or low efficiency, while feeding equipment can stably transport raw materials, reduce downtime, and improve production efficiency. Moreover, depending on the requirements of the product, it is sometimes necessary to add appropriate amounts of additives, such as pigments, plasticizers, and antioxidants, to the PE plastic particles, and they need to be thoroughly mixed to ensure the uniformity and stability of the product.
[0003] In the existing technology, traditional mixing feeders are usually equipped with a stirring device, which has a complex structure, high maintenance costs, and is prone to blockage due to material adhesion or agglomeration. Residual materials are difficult to clean thoroughly, which can easily cause cross-contamination and affect production hygiene. Therefore, we propose a mixing-free feeder to solve the above problems. Utility Model Content

Multiple annular grooves are formed on the top of the top plate, and annular connecting blocks are slidably connected to the inner walls of each groove. The tops of the connecting blocks are fixedly connected to the bottoms of the hoppers. Connecting pipes are fixedly connected to the bottoms of the hoppers. Multiple through holes are formed on the top of the top plate, and discharge pipes are fixedly connected to the inner walls of each hole. A multi-disc butterfly valve is fixedly installed on the outer wall of the discharge pipe. A conical collecting chamber is fixedly connected to the bottom of the output end of the electric push rod.

Two T-shaped columns are fixedly connected to the outer wall of the conical collecting chamber, and limiting discs are rotatably fitted onto the outer walls of the two T-shaped columns. A flow guiding component is provided inside the conical collecting chamber.
[0007] Preferably, the flow guiding component includes a connecting rod, the inner wall of the conical flow collecting chamber is fixedly connected to the top of the connecting rod, the bottom of the connecting rod is fixedly connected to a spiral blade, and the bottom of the conical flow collecting chamber is fixedly connected to a circular tube, the inner wall of the circular tube is slidably connected to the outer wall of the spiral blade. By setting the flow guiding component, accumulation or local concentration is avoided, and a mixing effect is achieved, while reducing the risk of blockage.
[0008] Preferably, the inner wall of the feeding pipe is slidably connected to the outer wall of the connecting pipe, and the inner walls of the multiple tapered pipes are slidably connected to the outer walls of the multiple feeding pipes respectively. The tapered pipes facilitate docking between the feeding pipes and the tapered pipes.

[0010] Preferably, two rubber extension strips are fixedly connected to the outer walls of both lower doors, and the two rubber extension strips increase the sealing between the lower doors and the conical manifold.
[0011] Preferably, the outer walls of the two limiting discs are pressed against the outer walls of the two lower doors respectively, and each of the outer walls of the two limiting discs is fixedly connected with an assist rod, which drives the limiting discs to rotate.
[0012] Preferably, the bottom of the circular tube is fixedly connected to a corrugated expansion tube, which has the ability to expand and contract to allow the conical collection chamber to move up and down.
[0013] Compared with the prior art, the advantages of this utility model are:
[0014] This solution uses a multi-flap butterfly valve to precisely control the ratio of various additives and PE particles, enabling independent metering and feeding. It ensures uniform material distribution without premixing, thus improving production efficiency.

[0023] The bottoms of multiple hoppers 2 are all fixedly connected to connecting pipes 4. The inner wall of the discharge pipe 5 is slidably connected to the outer wall of the connecting pipe 4. Multiple through holes are opened on the top of the top plate 1. The inner walls of the multiple through holes are all fixedly connected to the discharge pipes 5. A multi-disc butterfly valve 6 (DN150) is fixedly installed on the outer wall of the discharge pipe 5. The opening degree of the multi-disc butterfly valve 6 (DN150) directly affects the discharge amount. The flow rate and speed of the discharge can be controlled by adjusting the opening degree of the butterfly valve pneumatically.
[0024] A conical manifold 7 is fixedly connected to the bottom of the output end of the electric push rod 3. Multiple conical tubes 8 are evenly and interconnected on the top of the conical manifold 7. The inner walls of the multiple conical tubes 8 are slidably connected to the outer walls of the multiple feeding tubes 5 respectively, and feeding is carried out by docking. This also facilitates subsequent separation. Two lower side doors 9 are hinged to the outer wall of the conical manifold 7. Two rubber extension strips 10 are fixedly connected to the outer walls of the two lower side doors 9.
[0025] Two T-shaped columns 11 are fixedly connected to the outer wall of the conical collection chamber 7. The outer walls of the two T-shaped columns 11 are rotatably fitted with limiting discs 12. The limiting discs 12 rotate through the T-shaped columns 11. The outer walls of the two limiting discs 12 are pressed against the outer walls of the two lower doors 9 respectively. The outer walls of the two limiting discs 12 are fixedly connected with assist rods 13. The assist rods 13 facilitate the rotation of the limiting discs 12.
[0026] The conical manifold 7 is equipped with a flow guiding assembly, which includes a connecting rod 14. The inner wall of the conical manifold 7 is fixedly connected to the top of the connecting rod 14, and a spiral blade 16 is fixedly connected to the bottom of the connecting rod 14. The connecting rod 14 supports the spiral blade 16. A circular tube 15 is fixedly connected to the bottom of the conical manifold 7. The inner wall of the circular tube 15 is slidably connected to the outer wall of the spiral blade 16, and a corrugated telescopic tube 17 is fixedly connected to the bottom of the circular tube 15.
[0027] Working Principle: In operation, the top plate 1 is fixed to the top of the feed inlet of the existing PE particle processing equipment using existing bolts. Various additives and PE particles are placed into multiple hoppers 2. The multi-lobed butterfly valve 6 operates to meter and discharge the additives and PE particles, which are then discharged downwards through multiple discharge pipes 5. The particles enter the conical collecting chamber 7 through multiple conical pipes 8, then flow into the circular pipe 15, and are dispersed downwards along the spiral blades 16 into the corrugated expansion pipe 17. The guiding action of the spiral blades 16 creates a dispersion effect, preventing the additives and PE particles from concentrating. The bottom of the corrugated expansion pipe 17 can be connected to... On existing processing equipment, when cleaning residues, the electric push rod 3 drives the conical collection chamber 7 to move downwards, causing multiple conical tubes 8 to move downwards, and then pulls out multiple used hoppers 2 upwards, causing multiple connecting pipes 4 to slide out from the inside of multiple discharge pipes 5, and causing multiple annular connecting blocks 18 to slide out from multiple annular grooves, allowing multiple hoppers 2 to be cleaned individually. At the same time, the two ends of the discharge pipes 5 are exposed for cleaning. Two assist rods 13 drive two limit plates 12 to rotate. The two limit plates 12 rotate upwards, releasing the position fixation of the two lower side doors 9. Rotating the two lower side doors 9 exposes the inside of the conical collection chamber 7, making it convenient for cleaning.
