Description

Technical Field

[0001] This application relates to the field of feed pelleting equipment technology, and in particular to a quick-change device for pellet feed pelleting molds. Background Technology

[0002] Feed mainly refers to the food for animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. In the field of pelleted feed production, pelleting molds are key components, and their replacement efficiency and stability directly affect production efficiency.

[0003] In practical use, it has been found that traditional pelleting equipment relies heavily on bolt fastening or snap-fit ​​structures for die replacement, which has significant shortcomings: bolt fastening requires individual disassembly and installation, resulting in lengthy replacement times, and the bolts are prone to stripping due to long-term vibration, leading to die positioning deviations; while snap-fit ​​structures are easy to operate, their limiting strength is insufficient, and the die is prone to loosening due to compression and vibration during pelleting, causing unstable pellet sizes and even equipment failure. Furthermore, in traditional devices, the mixing and pelleting mechanisms are often independently driven, requiring separate speed adjustments, which not only increases energy consumption but also often results in excessive pellet cutting length errors due to poor synchronization, failing to meet the uniformity requirements of large-scale production. Therefore, we propose a quick-change pellet feed pelleting die device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, such as cumbersome pelleting die replacement process, high manual labor intensity and low efficiency, increased energy consumption, and inability to meet the requirements of pellet uniformity for large-scale production.

The limiting rod 502 is fixedly installed on the slide plate 501.

[0038] In this application, during operation, the feed raw materials are first poured into the top of the cylinder 1.

The stirring rod 203 on the stirring shaft 202 thoroughly mixes the feed raw materials within the cylinder 1, ensuring uniformity for subsequent pelleting. When the stirring shaft 202 rotates, it drives the reciprocating screw 301 to rotate via two meshing conical wheels 7 in the gear mechanism. The screw seat 302 on the reciprocating screw 301 reciprocates linearly along the seat hole at the bottom of the top box 2. The pelleting mechanism at the bottom of the screw seat 302 moves accordingly, allowing the cutter 304 on the left side of the mounting plate 303 to precisely cut the feed pellets extruded from the pelleting mold 4. This reciprocating motion enables continuous pelleting, ensuring uniform pellet length. When installing the granulator 4, the locking blocks 402 on the connecting plates 401 on the front and rear sides are aligned with the slots 102 at the bottom of the mounting base 101 and inserted. At this time, the sliding plate 501 of the limiting mechanism slides in the cavity 5, and the limiting rod 502 is locked into the limiting groove 504 on the outside of the locking block 402 under the elastic force of the spring 503. This can prevent the granulation mold from falling off and ensure that the granulation mold 4 is stably installed, preventing displacement due to vibration during the granulation process. When it is necessary to replace the granulation mold 4, by pulling the button 6 at one end of the limiting rod 502, the elastic force of the spring 503 can be overcome to make the limiting rod 502 disengage from the limiting groove 504, and the granulation mold 4 can be removed from the slot 102. This allows for quick disassembly and replacement of the granulation mold 4, meeting the production needs of different particle sizes and improving granulation efficiency.
