Description

Technical Field

[0001] This utility model relates to the field of feed pellet mill maintenance technology, and in particular to a device for disassembling and assembling the ring die and pressure roller of a feed pellet mill. Background Technology

[0002] With the development of the livestock industry, feed processing has seen increasingly larger single-plant capacity. Livestock feed mills with an annual output of 180,000 tons or more are springing up everywhere. The core equipment for producing pelleted feed is the ring die pellet mill. The mill's rollers continuously crush the powdered feed sprinkled on the inner surface of the ring die, continuously producing long cylindrical feed. A cutter then cuts the feed strips into shorter segments, becoming pelleted feed. A single roller weighs over 50 kg, and a single ring die weighs over 150 kg. Many factories rely on a single person to manually disassemble and assemble the rollers, or two or three people to lift and assemble the ring dies. This is labor-intensive, with few people capable of lifting them, and limited space, increasing the risk of foot injuries, back sprains, and high workplace injury costs. Replacing a ring die requires the pellet mill to be shut down for about an hour, resulting in low efficiency and supply disruptions. Against this backdrop, there is an urgent need for a device to reduce manual labor intensity, shorten downtime, and improve efficiency.

[0003] To solve the above problems, this utility model proposes a device for disassembling and assembling the ring die and pressure roller of a feed pellet mill. Utility Model Content

The design of the storage slots 12 facilitates the centralized storage and replacement of the pressure roller or ring die.

[0018] A travel rail 3 is fixedly installed at the top of the side wall of column 2. An electric hoist 4 is movably mounted on the travel rail 3. A motor 25 is fixedly installed on the side wall of the electric hoist 4, and the output shaft of the motor 25 is fixedly connected to the roller inside the electric hoist 4. A lifting box 5 is fixedly installed at the bottom of the electric hoist 4. A winding motor 6 is fixedly installed inside the lifting box 5. A winding roller 7 is fixedly installed on the output shaft of the winding motor 6. A steel wire rope 8 is fixedly connected inside the winding roller 7. A through hole 24 is opened at the bottom of the lifting box 5, and the steel wire rope 8 extends to the bottom of the lifting box 5 through the through hole 24. The combination of the travel rail 3, the electric hoist 4, the lifting box 5, and the winding mechanism enables flexible movement and precise positioning of the device in both horizontal and vertical directions.

[0019] A fixing block 9 is fixedly installed at the other end of the wire rope 8. Arc-shaped clamping plates 10 are rotatably installed on both sides of the fixing block 9. A base plate 11 is integrally formed at the bottom end of each arc-shaped clamping plate 10, and a snap-fit ​​assembly is provided on the base plate 11. The rotatable connection between the arc-shaped clamping plates 10 and the fixing block 9 allows them to better adapt to and cover ring dies or pressure rollers of different sizes.

[0020] The snap-fit ​​assembly includes three insertion rods 13 and three limiting rods 14. The three insertion rods 13 are fixedly mounted side-by-side on one side of the base plate 11. On the other side of the base plate 11, slots 15 are provided at the corresponding positions of the insertion rods 13. Sliding holes 16 are provided on the bottom side of each slot 15. The limiting rods 14 are slidably mounted within the sliding holes 16. The top of the limiting rod 14 is beveled, and a limiting groove 17 is provided on the bottom side of the insertion rod 13. The limiting rods 14 and the limiting grooves 17 are inserted into each other. Connecting plates 19 are fixedly mounted at the bottom of the three limiting rods 14. First springs 18 are sleeved on the outer side of each limiting rod 14. One end of the first spring 18 is fixedly connected to the connecting plate 19, and the other end of the first spring 18 abuts against the base plate 11. A pull ring 20 is fixedly mounted on the lower end face of the connecting plate 19. This achieves quick and reliable locking and separation of the two arc-shaped clamping plates 10, improving assembly and disassembly efficiency.

[0021] Buffer plates 21 are slidably mounted on the opposing surfaces of the two arc-shaped clamping plates 10. Multiple guide rods 22 are fixedly installed on each buffer plate 21, passing through the arc-shaped clamping plates 10 and forming a sliding fit. A second spring 23 is sleeved on the outer side of each guide rod 22. One end of the second spring 23 is fixedly connected to the end of the guide rod 22, and the other end is fixedly connected to the arc-shaped clamping plate 10. The buffer plates 21, guide rods 22, and second springs 23 provide a buffering effect during clamping, effectively preventing hard scratches on the surface of the pressure roller or ring die.

[0022] Working principle: When using this device, the operator first starts the electric hoist 4 and the winding motor 6, and releases the wire rope 8 through the winding roller 7. The arc-shaped clamping plate 10 assembly suspended at the end of the wire rope 8 is smoothly moved to the front of the pressure roller or ring die to be disassembled. Then, the operator manually covers the outer periphery of the pressure roller or ring die with the two arc-shaped clamping plates 10 on both sides, and quickly locks them with the snap-fit ​​assembly. Specifically, the insertion rod 13 fixed on one side of the base plate 11 is aligned and inserted into the corresponding slot 15 on the other side of the base plate 11. During the insertion process, the end of the insertion rod 13 contacts the inclined surface of the top of the limiting rod 14 and applies pressure to force the limiting rod 14 to slide downward along the sliding hole 16. This action simultaneously stretches the first spring sleeved on the outside of the limiting rod 14. Spring 18; When the insertion rod 13 is continuously inserted until the limiting groove 17 on it moves to the same axis as the limiting rod 14, the compressed first spring 18 immediately releases its elastic potential energy, driving the limiting rod 14 to reset upward and accurately lock into the limiting groove 17, thereby completing the mechanical interlock of the insertion rod 13, making the two bottom plates 11 firmly connected, and stably clamping the pressure roller or ring die in the containment space formed by the two arc-shaped clamping plates 10 and the buffer plate 21; When it is necessary to unlock, the operator only needs to pull down the pull ring 20 below the connecting plate 19, and through the connecting plate 19, all the limiting rods 14 will move downward against the elastic force of the first spring 18, so that their tops completely exit the limiting groove 17, and the two bottom plates 11 can be easily separated and the clamped parts can be released.

[0023] After the components are reliably secured, the electric hoist 4 is controlled to move along the travel rail 3 again, and the winding motor 6 is coordinated to adjust the length of the wire rope 8, so that the pressure roller or ring die, which is securely hoisted by the arc-shaped clamp 10, is safely and smoothly transferred to the vicinity of the designated storage slot 12 at the bottom of the side wall of the column 2. The operator can then push the disassembled old components into the empty storage slot 12 for temporary storage or move them out of the work position. The new pressure roller or new ring die, which has been placed in other storage slots 12 in advance, can be hoisted in the same way, thereby realizing a fast and orderly replacement operation, improving maintenance efficiency and reducing labor intensity.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
