Description

Technical Field

[0001] This utility model relates to the field of metal baling machine technology, specifically a continuous double-discharge metal baling machine. Background Technology

[0002] In the field of metal scrap baling machines, traditional metal balers are mostly single-outlet devices, meaning that only one baler can be produced at a time after the metal scrap is compressed into a block, which presents a significant efficiency bottleneck. Taking aluminum shavings, iron shavings, and copper shavings as examples, existing equipment generally adopts a unidirectional compression structure, resulting in limited capacity per unit time and failing to meet the high-output demands of modern processing centers. In addition, the compressed metal baler frequently retracts, with approximately 15% to 20% of the material requiring secondary processing due to defects in the anti-retraction structure, increasing energy consumption and reducing the density of the finished product. Furthermore, single-machine operation requires dedicated personnel to monitor feeding and clean up waste liquid, resulting in high labor costs.

[0003] While some existing improved compression devices attempt to optimize their structure, they mostly focus on improving a single function and fail to fundamentally solve various efficiency and quality issues. For example, some devices reduce material backflow to some extent, but the discharge rate is not significantly improved; others increase the discharge rate but introduce new shortcomings in compression density and waste liquid treatment. Moreover, these improved devices are often more complex in structure, increasing the manufacturing cost and maintenance difficulty of the equipment.

[0004] The large quantities of metal shavings generated during metal processing, if not efficiently compressed and packaged, not only occupy significant storage space but also increase transportation costs. Furthermore, since the metal shavings may contain impurities such as oil, failure to effectively separate and treat waste liquids during compression can pollute the environment and affect the quality of the compressed metal blocks. Therefore, the market urgently needs a dual-discharge material compression device that can comprehensively solve these problems, improving the efficiency and quality of metal processing waste treatment, reducing costs, and minimizing environmental impact.

[0025] In summary, this continuous dual-discharge material compression device offers significant advantages. Firstly, the dual-discharge design supports continuous operation, eliminating downtime for switching and greatly improving production efficiency, especially suitable for high-volume scenarios. Secondly, the anti-reverse mechanism effectively prevents metal scrap from retracting during discharge, ensuring smooth and unobstructed flow and reducing the risk of blockages. The inclined discharge mechanism guides material to slide out quickly via an inclined track, shortening discharge time and improving overall smoothness. The feeding auger and stirring mechanism in the pre-compression mechanism work together to pre-compress the material and evenly input it into the main compression mechanism, optimizing compression density and improving the quality of the final product. The lateral opening mechanism flexibly switches the discharge path through mold movement, enhancing the device's versatility and adaptability to meet different process requirements. The hydraulic mechanism provides stable and reliable power output, combined with the electrical control box for automated control, reducing manual intervention and improving operational convenience. The compact overall structure, along with the protective shell and tie rod design, enhances the device's rigidity and durability, reducing vibration and wear and extending its service life. Simultaneously, the waste liquid collection tank effectively treats waste liquid generated during the compression process, maintaining a clean working environment and reducing maintenance costs. These beneficial effects together achieve efficient, stable, and flexible material compression, making it suitable for various material handling applications such as metal scrap.

[0026] The working method, or working principle, of a continuous double-discharge metal baler provided by this utility model includes the following steps: S1. Feeding: The metal scrap is fed into the pre-compression silo body 303 from the feed port 304 of the pre-compression mechanism 3. The first motor 307 and the second motor 311 are started to work. The second reducer 310 drives the stirring mechanism 309 to rotate, and the first reducer 306 drives the feeding auger mechanism 308 to rotate. The metal scrap is first stirred by the stirring mechanism 309, and then the spiral blades on the feeding auger mechanism 308 break and break the metal scrap. It is discharged in an orderly manner from the first pre-compression outlet 305, enters the material channel 301 through the material inlet 312, and then falls continuously into the U-shaped cavity 210-2 of the compression chamber 210 below from the second pre-compression outlet 313. S2, First batch pre-compression: The metal scrap in the U-shaped cavity 210-2 of the compression chamber 210 is initially compressed and shaped by the piston rod of the pre-compression cylinder 302; S3, First Batch Main Compression: The transverse door opening mechanism 7 is in the initial position, that is, when the piston rod in the door opening cylinder 702 is in the retracted state, that is, when the mold sleeve 704 is in the initial position, the first material processing through hole 705a of the mold sleeve 704 is aligned with the first push through hole 207a and the left first push rod 215a, while the second material processing through hole 705b is aligned with the pressing through hole 208; the main push cylinder 211 of the main compression mechanism 2 is started, driving the piston stamping rod 212, the movable end cover 214, and the first push rod 215a and the second push rod 215b to move forward together. The piston stamping rod 212 first enters the U-shaped cavity 210-2 from the pressing positioning hole 210-4, and pushes the U-shaped cavity 210-2 through the pre-processed material. The compressed metal scrap is pushed forward and passes through the pressing through hole 208 and the pressing round hole 209. Finally, the first batch of metal scrap is pressed against the front cover 201 and compacted into a round cake shape through the second material processing through hole 705b of the mold sleeve 704 and temporarily stored in the second material processing through hole 705b. At the same time, the first push rod 215a passes through the first push through hole 207a, the third round door hole 206c, the first push through hole 207a, the first round door hole 206a, and finally pushes out from the first main pressing outlet 4a. The second push rod 215b passes through the second push through hole 207b, the fourth round door hole 206d, and the second round door hole 206b, and finally pushes out from the second main pressing outlet 4b. S4. Returning to position after the first batch of main compression: The main push cylinder 211 of the main compression mechanism 2 drives the piston stamping rod 212, the movable end cover 214, the first push rod 215a and the second push rod 215b to return to the initial position together. S5. Second batch pre-compression: The second batch of metal scrap falling into the U-shaped cavity 210-2 of the compression chamber 210 is initially compressed and shaped by the piston rod of the pre-compression cylinder 302. S6. Mold sleeve repositioning: In step S4, when the main push cylinder 211 returns, the door opening cylinder 702 drives the mold sleeve 704 to move forward to the designated position, that is, when the front end of the mold sleeve 704 is aligned with the front end of the material passage 205, the first material processing through hole 705a is aligned with the pressing through hole 208. At this time, the metal scrap that was temporarily stored in the second material processing through hole 705b in step S3 and compacted into a circular cake shape is aligned with the second push through hole 207b and the second push rod 215b as the mold sleeve 704 moves. S7. Second Batch Main Compression and First Batch Pushing: The main cylinder 211 of the main compression mechanism 2 drives the piston stamping rod 212, the movable end cover 214, the first push rod 215a, and the second push rod 215b forward together. The piston stamping rod 212 first enters the U-shaped cavity 210-2 from the pressing positioning hole 210-4, pushing the pre-compressed metal scrap in the U-shaped cavity 210-2 further forward and through the pressing through hole 208 and the pressing round hole 209. Finally, the second batch of metal scrap is held at the front end through the first material processing through hole 705a of the die sleeve 704. The material is compacted into a circular cake shape on the cover 201 and temporarily stored in the first material processing through hole 705a. At the same time, the first push rod 215a passes through the first push through hole 207a, the third circular door hole 206c, the first push through hole 207a, the first circular door hole 206a, and finally is pushed out from the first main pressure outlet 4a. The second push rod 215b passes through the second push through hole 207b and passes through the fourth circular door hole 206d and the second circular door hole 206b, and is finally pushed out from the second main pressure outlet 4b, completing the first batch of material pushing. S8. After the second batch of main compression, the main compression mechanism 2's main push cylinder 211 drives the piston stamping rod 212, the movable end cover 214, the first push rod 215a, and the second push rod 215b to return to their initial positions. S9. Third batch pre-compression: The piston rod of the pre-compression cylinder 302 performs preliminary compression and shaping on the third batch of metal scrap falling into the U-shaped cavity 210-2 of the compression chamber 210. S10, Mold sleeve return: In step S8, when the main push cylinder 211 returns, the door opening cylinder 702 drives the mold sleeve 704 back to the initial position in step S3, so that the first material processing through hole 705a is aligned with the first push through hole 207a and the left first push rod 215a again, and the second material processing through hole 705b is aligned with the pressing through hole 208 again. At this time, the metal scrap temporarily stored in the first material processing through hole 705a in step S7 and compacted into a circular cake shape is aligned with the first push through hole 207a and the first push rod 215a as the mold sleeve 704 moves. S11, Third Batch Main Compression and Second Batch Pushing: The main compression mechanism 2's main push cylinder 211 is activated, driving the piston stamping rod 212, movable end cover 214, first push rod 215a, and second push rod 215b forward together. The piston stamping rod 212 first enters the U-shaped cavity 210-2 from the pressing positioning hole 210-4, further pushing the pre-compressed metal scrap in the U-shaped cavity 210-2 forward and then through the pressing through hole 208 and pressing round hole 209. Finally, the third batch of metal scrap is pressed against the front end cover through the second material processing through hole 705b of the die sleeve 704. The material is compacted into a circular cake shape and temporarily stored in the second material processing through hole 705b. At the same time, the first push rod 215a passes through the first push through hole 207a and pushes the compacted circular cake-shaped metal scrap, which is stored there, through the third circular door hole 206c, the first push through hole 207a, and the first circular door hole 206a in sequence, and is finally pushed out from the first main pressure discharge port 4a, completing the second batch of pushing. Meanwhile, the second push rod 215b passes through the second push through hole 207b, the fourth circular door hole 206d, and the second circular door hole 206b in sequence, and is finally pushed out empty from the second main pressure discharge port 4b. S12. Under the continuous feeding and emptying in step S1, repeat steps S2 to S11 to realize the alternating and continuous discharge of compressed circular metal scrap from the first main pressure discharge port 4a and the second main pressure discharge port 4b, and then slide down along the inclined discharge track 602 of the inclined discharge mechanism 6.

[0027] After the circular, disc-shaped metal scrap is discharged in steps S7 and S11 above, the anti-reverse gear 502 of the anti-reverse mechanism 5 is used to prevent the metal scrap from retracting through a one-way rotation structure, ensuring smooth discharge.
