Description

Technical Field

[0001] This utility model relates to the technical field of high-efficiency pressing device for the production of chicken oil as a feed additive, and more specifically, it relates to a high-efficiency pressing device for the production of chicken oil as a feed additive. Background Technology

[0002] In the field of chicken oil production for feed additives, high-efficiency pressing equipment is the core equipment for extracting chicken oil. Its technical performance and operational reliability directly affect the yield and quality of chicken oil. However, the chicken oil pressing equipment currently on the market has significant technical defects in terms of operation mode, power transmission and overload protection mechanism. These problems not only affect pressing efficiency, but may also lead to equipment damage and production interruption.

[0003] The primary problem is the outdated manual pressing method, which severely restricts production efficiency: First, traditional manual pressing requires operators to apply continuous force, resulting in extremely high labor intensity; second, it is difficult to maintain stable pressure during manual pressing, leading to inconsistent oil extraction rates; third, the discontinuity of manual operation results in low production efficiency, failing to meet the needs of large-scale production; furthermore, prolonged repetitive operations can easily cause occupational injuries to operators; finally, this outdated production method not only increases labor costs but also makes it difficult to guarantee consistent product quality, seriously affecting the company's market competitiveness.

[0004] Secondly, the power transmission system is fragile and poses significant safety hazards: Firstly, although some improved equipment uses a motor to drive the pressing rod for pressing, the connection structure between the motor and the pressing rod is too simple and direct. During the pressing process, when the raw material is unevenly distributed or contains hard impurities, blockages or jamming can easily occur in the oil pressing chamber. When the pressing rod encounters resistance and cannot rotate, mechanical stress will concentrate at the connection between the motor and the pressing rod, causing the connecting parts to break or deform. In addition, sudden jamming can cause the motor to be subjected to excessive load instantly, leading to serious damage such as overheating and winding burnout. Finally, this structural design defect not only increases the frequency and cost of equipment maintenance, but may also cause the production line to be shut down for a long time due to mechanical failure, resulting in significant economic losses for the enterprise.

[0005] The most serious problem is the instability of the overload protection mechanism. Although some equipment is equipped with overload protection devices and adjustment functions, there are technical defects in the instability of the adjustment structure: First, during long-term operation, continuous mechanical vibration will cause the fastening parts in the adjustment structure to gradually loosen; second, the centrifugal force generated by the high-speed operation of the motor will apply additional dynamic load to the adjustment mechanism, accelerating the displacement of the adjustment structure; in addition, after the adjustment mechanism undergoes a slight displacement, the trigger threshold of the overload protection will change accordingly, either becoming too sensitive and causing frequent shutdowns, or becoming sluggish and unable to protect the equipment in time; finally, the instability of this protection mechanism not only reduces the operational reliability of the equipment, but may also cause cascading damage to the motor and transmission system, greatly shortening the service life of the entire pressing unit.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a high-efficiency pressing device for the production of chicken oil as a feed additive, which has the following beneficial effects:

[0019] 1. The oil pressing device, through the coordinated operation of the motor, oil outlet, oil pressing chamber, feeding chamber, and pressing rod, constructs a highly efficient and automated pressing system. The motor serves as the power source, providing stable and continuous rotational power to the pressing rod. The design of the feeding chamber allows the crushed chicken to enter the oil pressing chamber. Inside the oil pressing chamber, the pressing rod both transports and squeezes the raw materials during rotation, enabling continuous operation. The design of the oil outlet ensures that the pressed oil can flow out and be collected in a timely manner. This highly integrated oil pressing device completely abandons the traditional manual pressing method, not only significantly improving production efficiency but also ensuring the consistency of oil extraction rate through stable mechanical pressure. The automated operation of this device eliminates repetitive labor for operators, avoids occupational injuries, and achieves continuous production, meeting the needs of large-scale production, effectively ensuring the stability of product quality, and enhancing the company's market competitiveness.

[0020] 2. The coupling device, through the ingenious coordination of bushings, shafts, rotating sleeves, slots, inclined grooves, inclined plates, linkage grooves, linkage sleeves, linkage blocks, and movable blocks, forms an overload protection transmission system. The bushings and shafts, as the hub connecting the motor and the transmission system, drive the inclined plate to rotate through the inner inclined groove. The receiving groove on the inner side of the movable block, in conjunction with the push spring and push block, achieves a reliable connection with the shaft slot. When blockage occurs inside the oil pressing chamber, the coupling device, through the rounded corner design between the slot and the push block, allows the push block to slide out of the slot under resistance and compress the push spring, enabling the motor to drive the bushing to idle. The trigger threshold can be flexibly adjusted according to material and processing characteristics. This innovative coupling design completely solves the technical defects of the fragile connection between the motor and the pressing rod in traditional equipment. It not only effectively prevents breakage at the connection point but also avoids the risk of the motor burning out due to overload through the idle protection mechanism. The precise coordination of the overall structure ensures efficient force transmission during normal operation of the transmission system, while rapid response and protection under abnormal conditions greatly reduces the frequency and cost of equipment maintenance.

[0021] 3. The locking mechanism, through the synergistic action of a rotating plate, rotating block, movable spring, fixed block, rotating hole, sliding rod, sliding sleeve, shifting spring, shifting block, and circular block, constructs a stable protection system. The rotating plate, in cooperation with the rotating block, movable spring, and fixed block, achieves a preliminary limiting function; the design of the sliding rod and sliding sleeve, combined with the return spring, forms a reliable locking mechanism; the combination of the shifting block and shifting spring, along with the limiting function of the circular block, ensures the stability after adjustment. This innovative locking design completely overcomes the problem of instability in the overload protection mechanism of traditional equipment. Through multiple locking mechanisms, it ensures that the adjusted settings will not shift due to equipment vibration or centrifugal force, effectively avoiding the drift of the overload protection threshold. This mechanism can flexibly adjust the trigger threshold according to different raw material characteristics and lock the parameters after setting, ensuring stable operation for a long time, significantly improving the reliability and service life of the equipment, and providing a solid guarantee for the continuous production of enterprises.

[0031] Please see Figures 1-5 A high-efficiency pressing device for chicken oil production as a feed additive includes a base 1, on which a pressing device is detachably mounted. A coupling device is provided on the base 1, comprising a bushing 2, a shaft 3, a rotating sleeve 4, a groove 5, an inclined groove 6, an inclined plate 7, a linkage groove 8, a linkage sleeve 9, a linkage block 10, and a movable block 11. The bushing 2 is movably disposed on the outside of the shaft 3, the rotating sleeve 4 is rotatably mounted on the outside of the bushing 2, the groove 5 is located on the outside of the shaft 3, the inclined groove 6 is located on the inside of the bushing 2, the inclined plate 7 slides within the inclined groove 6, the linkage groove 8 is spirally located on the inside of the rotating sleeve 4, the linkage sleeve 9 is located on the inside of the rotating sleeve 4, the linkage block 10 is fixedly disposed on the outside of the linkage sleeve 9 and slides within the linkage groove 8, and the movable block 11 is fixedly connected to one side of the inclined plate 7. A locking mechanism is installed on the outside of sleeve 2. The locking mechanism includes a rotating plate 12, a rotating block 13, a movable spring 14, a fixed block 15, a rotating hole 16, a sliding rod 17, a sliding sleeve 18, a shifting spring 19, a shifting block 20, and a circular block 21. The rotating plate 12 is rotatably installed on the outside of sleeve 2. The rotating block 13 is fixedly installed on one side of the rotating plate 12. The two ends of the movable spring 14 are respectively connected to the rotating block 13 and the fixed block 15. The fixed block 15 is fixedly installed on the outside of sleeve 2. The rotating hole 16 is opened on the rotating plate 12. The sliding rod 17 is fixedly connected to one side of the sliding sleeve 18. The sliding sleeve 18 is located on the outside of sleeve 2. The two ends of the shifting spring 19 are respectively connected to two adjacent shifting blocks 20. The shifting blocks 20 are movably located on one side of the rotating sleeve 4. Multiple circular blocks 21 are fixedly installed on the outside of sleeve 2.

[0032] The pressing device includes a motor 22, an oil outlet 23, an oil pressing chamber 24, a feeding chamber 25, and a pressing rod 26. The motor 22 is detachably mounted on the base 1, and the output end of the motor 22 is connected to the bushing 2. The oil pressing chamber 24 is detachably mounted on one side of the feeding chamber 25, and the feeding chamber 25 is located above the base 1. The pressing rod 26 is rotatably mounted in the oil pressing chamber 24, and one end of the pressing rod 26 is connected to the shaft 3.

[0033] In this embodiment, when the equipment is needed, the shredded chicken is first placed into the feeding hopper 25, and then the motor 22 is turned on. The motor 22 drives the bushing 2 to rotate, and then the bushing 2 drives the inclined plate 7 and the movable block 11 to rotate through the inclined groove 6. Then the movable block 11 drives the inner receiving groove 27 to rotate, and then the receiving groove 27 drives the push spring 28 and the push block 29 to rotate, so that the push block 29 cooperates with the slot 5 to drive the shaft 3 to rotate. Then the shaft 3 drives the pressing rod 26 to rotate in the oil pressing chamber 24, realizing the conveying and pressing of the chicken. Then the pressed oil will pass through the oil outlet. The squeezed chicken meat flows out through the other end of the oil pressing chamber 24. When the oil pressing chamber 24 becomes blocked, the pressing rod 26 and the shaft 3 cannot rotate. Then the shaft 3 and the slot 5 stop rotating. The inner wall of the slot 5 presses against the outer side of the push block 29. Due to the rounded corner design of the inner wall of the slot 5 and the outer wall of the push block 29, the push block 29 gradually slides out of the slot 5 and gradually slides into the receiving groove 27 to press against the push spring 28. This causes the motor 22 to drive the bushing 2 to rotate idling, thus realizing idling protection, connection breakage protection and motor 22 overload protection.

[0034] Please see Figures 3-5 As a further implementation of the overall device: a storage groove 27 is provided on the inner side of the movable block 11, a push spring 28 is movably provided in the storage groove 27, and a push block 29 is connected to the other end of the push spring 28. The push block 29 is inserted into the slot 5.

[0035] A return spring 30 is movably sleeved on the outer side of the slide rod 17. One end of the return spring 30 is connected to the slide sleeve 18, and the other end of the return spring 30 is in contact with the rotating plate 12.

[0036] The shifting block 20 has a shifting groove 31, and a plurality of shifting rails 32 are fixed on one side of the rotating sleeve 4. The shifting groove 31 is adapted to the shifting rails 32.

[0037] A slider 33 is fixedly provided on the inner side of the sliding sleeve 18, and a groove 34 is provided on the outer side of the bushing 2, with the slider 33 slidably disposed in the groove 34.

[0038] A shifting wheel 35 is provided on one side of the shifting block 20, which rotates and engages between the two corresponding circular blocks 21.

[0039] A movable plate 36 is connected to one side of the movable block 11, and a movable groove 37 is opened on one side of the linkage sleeve 9. The movable plate 36 slides in the movable groove 37.

[0040] More specifically, when the protection trigger threshold needs to be adjusted, firstly, rotate the rotating plate 12 in the forward direction, causing the rotating hole 16 to rotate in the forward direction. The rotating plate 12 also causes the rotating block 13 to rotate in the forward direction. Then, the rotating block 13, in conjunction with the fixed block 15, compresses the movable spring 14. When the movable spring 14 is compressed to its limit, the rotating hole 16 rotates to a position concentric with the slide rod 17. Then, push the sliding sleeve 18, causing the sliding sleeve 18 to drive the slider 33 to slide along the slide groove 34. The sliding sleeve 18 also causes the slide rod 17 to pass into the rotating hole 16. Simultaneously, the sliding sleeve 18, in conjunction with the rotating plate 12, compresses the reset spring 30. Then, the sliding sleeve 18 no longer limits the outer side of the shift wheel 35. Finally, rotate the rotating sleeve 4 in the forward direction, causing... The rotating sleeve 4 drives multiple shifting rails 32 on one side to rotate in the forward direction. Then, the shifting rails 32, in conjunction with the shifting grooves 31, drive multiple shifting blocks 20 to rotate in the forward direction. Then, the shifting blocks 20 drive the shifting wheels 35 to roll out between two circular blocks 21. Then, the circular blocks 21 drive the shifting blocks 20 to slide outward along the shifting rails 32 and the shifting grooves 31. Then, the shifting blocks 20 will drive the shifting springs 19 to stretch outward. At the same time, the rotating sleeve 4 will drive the linkage grooves 8 on the inner side to rotate in the forward direction. Then, the linkage blocks 10 will slide relative to each other along the linkage grooves 8. Then, the linkage blocks 10 will drive the linkage sleeve 9 to slide to one side. Then, the linkage sleeve 9 will push the movable block 11 on one side to move. Then, the movable block 11 will drive the storage groove 27 on the inner side to slide, and the storage groove 27... 7 will cause the push spring 28 and push block 29 to slide. At the same time, the movable block 11 will cause the inclined plate 7 on the other side to slide along the inclined groove 6. Then the inclined plate 7 will cause the movable block 11 to move inward. At the same time, the movable block 11 will cause the movable plate 36 on one side to slide inward along the movable groove 37, and cause the movable block 11 to move the storage groove 27. Then the distance between the inner wall of the storage groove 27 and the push block 29 will decrease, causing the push spring 28 to be squeezed. Then the pushing force applied by the push spring 28 to the push block 29 will increase, so that the push block 29 needs to withstand more force to disengage from the slot 5, thus making the protection mechanism less likely to be triggered. When it is necessary to reduce the pushing force applied by the push spring 28 to the push block 29, the rotating sleeve 4 can be rotated in the opposite direction. When the trigger threshold is adjusted... After alignment, stop rotating the rotating sleeve 4 and allow the shifting rail 32 to move the shifting block 20 between the two corresponding circular blocks 21 via the shifting groove 31. Then, the shifting spring 19 resets and pulls the shifting block 20 to slide inward along the shifting rail 32 and the shifting groove 31. The shifting block 20 then drives the shifting wheel 35 to engage between the two corresponding circular blocks 21. Then, release the sliding sleeve 18, and the reset spring 30 pushes the sliding sleeve 18 to slide reset. The sliding sleeve 18 then drives the inner slider 33 to slide reset along the sliding groove 34, and the sliding sleeve 18 also drives the sliding rod 17 to slide reset. When the reset spring 30 has fully reset, the sliding rod 17 no longer limits the rotating plate 12 through the rotating hole 16. Then, the movable spring 14 pushes the rotating block 13 to rotate reset.Then, the rotating block 13 drives the rotating hole 16 to rotate and reset to a position not corresponding to the slide rod 17 via the rotating plate 12. The slide rod 17 then provides limiting support for the sliding sleeve 18, and together with the slider 33 and the groove 34, limits the sliding sleeve 18, preventing it from sliding. The inner wall of the sliding sleeve 18 then limits the outer side of the shift wheel 35, preventing the shift wheel 35 and the shift block 20 from moving outwards. This achieves rotational limitation on the rotating sleeve 4, preventing it from rotating and ensuring the structural stability after threshold adjustment, thereby ensuring the stable operation of the oil pressing process.

[0041] In summary, when using or operating the equipment: First, the shredded chicken is placed into the feeding hopper 25. Then, the motor 22 is turned on, driving the bushing 2 to rotate. The bushing 2 then drives the inclined plate 7 and the movable block 11 to rotate via the inclined groove 6. The movable block 11 then drives the inner receiving groove 27 to rotate, which in turn drives the push spring 28 and the push block 29 to rotate. This causes the push block 29 to engage with the slot 5, driving the shaft 3 to rotate. The shaft 3 then drives the pressing rod 26 to rotate within the oil pressing chamber 24, thus conveying and pressing the chicken. The pressed oil is then extracted... The oil flows out through the outlet 23, and the squeezed chicken meat is output through the other end of the oil pressing chamber 24. When the oil pressing chamber 24 becomes blocked, the pressing rod 26 and the shaft 3 cannot rotate. Then the shaft 3 and the slot 5 stop rotating. Then the inner wall of the slot 5 presses against the outer side of the push block 29. Due to the rounded corner design of the inner wall of the slot 5 and the outer wall of the push block 29, the push block 29 gradually slides out of the slot 5 and gradually slides into the receiving groove 27 to press against the push spring 28. This causes the motor 22 to drive the bushing 2 to rotate idling, thereby realizing the idling protection, the breakage protection of the connection, and the overload protection of the motor 22.

[0042] When the protection trigger threshold needs to be adjusted, first rotate the rotating plate 12 clockwise, causing the rotating hole 16 to rotate clockwise. The rotating plate 12 also causes the rotating block 13 to rotate clockwise. Then, the rotating block 13, in conjunction with the fixed block 15, compresses the movable spring 14. When the movable spring 14 is compressed to its limit, the rotating hole 16 rotates to a position concentric with the slide rod 17. Then, push the sliding sleeve 18, causing the sliding sleeve 18 to drive the slider 33 to slide along the slide groove 34. The sliding sleeve 18 also causes the slide rod 17 to pass into the rotating hole 16. Simultaneously, the sliding sleeve 18, in conjunction with the rotating plate 12, compresses the reset spring 30. Then, the sliding sleeve 18 no longer limits the outer side of the shift wheel 35. Finally, rotate the rotating sleeve 4 clockwise, causing the rotating sleeve 4 to rotate clockwise. The system drives multiple shift rails 32 on one side to rotate in the forward direction. Then, the shift rails 32, in conjunction with the shift grooves 31, drive multiple shift blocks 20 to rotate in the forward direction. The shift blocks 20 then drive the shift wheels 35 to roll out between two circular blocks 21. The circular blocks 21 then drive the shift blocks 20 to slide outward along the shift rails 32 and shift grooves 31. The shift blocks 20 then drive the shift springs 19 to stretch outward. Simultaneously, the rotating sleeve 4 drives the inner linkage groove 8 to rotate in the forward direction. The linkage block 10 then slides relative to the linkage groove 8. The linkage block 10 then drives the linkage sleeve 9 to slide to one side. The linkage sleeve 9 then pushes the movable block 11 on one side to move. The movable block 11 then drives the inner storage groove 27 to slide, and the storage groove 27 will... The push spring 28 and push block 29 slide together. Simultaneously, the movable block 11 drives the inclined plate 7 on the other side to slide along the inclined groove 6. Then, the inclined plate 7 drives the movable block 11 to move inwards. At the same time, the movable block 11 drives the movable plate 36 on one side to slide inwards along the movable groove 37, causing the movable block 11 to move the storage groove 27. The distance between the inner wall of the storage groove 27 and the push block 29 decreases, causing the push spring 28 to be compressed. This increases the pushing force exerted by the push spring 28 on the push block 29, requiring the push block 29 to withstand greater force to disengage from the slot 5, thus making the protection mechanism less likely to be triggered. When the pushing force exerted by the push spring 28 on the push block 29 needs to be reduced, the rotating sleeve 4 can be rotated in the opposite direction. When the trigger threshold is adjusted... Afterwards, stop rotating the rotating sleeve 4, and allow the shifting rail 32 to move the shifting block 20 between the two corresponding circular blocks 21 via the shifting groove 31. Then, the shifting spring 19 resets and pulls the shifting block 20 to slide inward along the shifting rail 32 and the shifting groove 31. Then, the shifting block 20 drives the shifting wheel 35 to engage between the two corresponding circular blocks 21. Then, release the sliding sleeve 18, and the reset spring 30 pushes the sliding sleeve 18 to slide reset. Then, the sliding sleeve 18 will drive the inner slider 33 to slide reset along the sliding groove 34, and the sliding sleeve 18 will drive the sliding rod 17 to slide reset. When the reset spring 30 is fully reset, the sliding rod 17 no longer limits the rotating plate 12 through the rotating hole 16. Then, the movable spring 14 pushes the rotating block 13 to rotate reset.Then, the rotating block 13 drives the rotating hole 16 to rotate and reset to a position not corresponding to the slide rod 17 via the rotating plate 12. The slide rod 17 then provides limiting support for the sliding sleeve 18, and together with the slider 33 and the groove 34, limits the sliding sleeve 18, preventing it from sliding. The inner wall of the sliding sleeve 18 then limits the outer side of the shift wheel 35, preventing the shift wheel 35 and the shift block 20 from moving outwards. This achieves rotational limitation on the rotating sleeve 4, preventing it from rotating and ensuring the structural stability after threshold adjustment, thereby ensuring the stable operation of the oil pressing process.
