[0021] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0022] A scrap iron recycling production device includes a collection box 301. A fixed shaft 105 is fixedly connected inside the collection box 301. Two rotating plates 101 are rotatably connected to the fixed shaft 105. Multiple biting pieces 104 are fixedly connected to the lower ends of the two rotating plates 101. The multiple biting pieces 104 on the two rotating plates 101 are arranged alternately. Each biting piece 104 has serrations at its upper end. The multiple biting pieces 104 are rotatably connected to the fixed shaft 105. The lower end of the collection box 301 is arc-shaped. A rotating frame 201 is fixedly connected to the lower ends of the two rotating plates 101. A pressing mechanism is provided on the rotating frame 201.

[0023] See Figure 1-4 ,

[0024] When recycling scrap thin iron sheets, the first step is to use a crusher to crush them. The crushed scrap iron sheets are smaller in size, making them easier to clean and recycle. Then they are transported. However, the small pieces of scrap iron are scattered on the ground and are difficult to collect. Furthermore, due to the sharp nature of the small pieces of scrap iron, it is difficult to find suitable containers during transportation, and they are also prone to wear and tear on the hopper of the transport vehicle, which increases the difficulty and cost of transportation.

[0025] When using the recycling production device of this application, the worker first places the scrap thin iron sheet on two rotating plates 101. The scrap thin iron sheet can automatically slide down the inclined surface of the rotating plates 101. Since the two rotating plates 101 are V-shaped, the scrap thin iron sheet automatically slides to the middle position of the two rotating plates 101. The scrap thin iron sheet is located above multiple interlocking plates 104. At this time, by controlling the two rotating plates 101 to generate reciprocating rotation in opposite directions, the multiple interlocking interlocking plates 104 can generate reciprocating rotation in opposite directions. This causes the shearing force generated between the multiple interlocking interlocking plates 104 to shear the iron sheet, thereby achieving the crushing of the iron sheet. The crushed iron sheet can fall out through the gaps between the interlocking plates 104.

[0026] Since each biting piece 104 has serrations on its upper end, the biting force between the biting pieces 104 can be increased, and the friction between the biting piece 104 and the iron sheet can be increased, thereby preventing slippage between the iron sheet and the biting piece 104, thus preventing ineffective crushing and improving the crushing efficiency of the iron sheet.

[0027] The broken pieces of iron fell into the collection box 301.

[0028] Since the lower ends of the two rotating plates 101 are fixedly connected to the rotating frame 201, and the rotating frame 201 is equipped with a pressing mechanism, when the two rotating plates 101 rotate relative to each other, they can drive the two rotating frames 201 to rotate relative to each other. Thus, the two pressing mechanisms interact to generate extrusion force, which extrudes the broken iron pieces, compresses and shapes the iron pieces into blocks, reduces the space occupied by the bulk iron pieces, improves the portability of iron piece transportation, and facilitates further processing of scrap iron.

[0029] Because the lower end of the collection box 301 is arc-shaped, the two rotating frames 201 rotate around the axis of the collection box 301 when they rotate, so that the pressing mechanism can scrape the iron pieces inside the collection box 301 and avoid leakage.

[0030] This application integrates the functions of crushing, extruding, and preventing leakage of scrap iron sheets, solving the problems of small scrap iron pieces being scattered and difficult to collect after traditional crushing, high wear and tear during transportation, and large space occupation. It improves recycling efficiency and portability. The collection box 301 serves as a temporary storage space for the crushed iron sheets, accommodating the block-shaped scrap iron formed by the pressing mechanism. The arc-shaped design, combined with the rotation of the frame, ensures that the pressing mechanism can fully scrape the iron sheets inside the box, avoiding leakage and improving the integrity of collection.

[0031] The fixed shaft 105 serves as the rotation axis of the rotating plate 101, ensuring that the two rotating plates rotate synchronously and stably in a reciprocating direction relative to each other, providing a power basis for subsequent shearing and extrusion actions; the V-shaped design of the rotating plate 101 allows the waste thin iron sheet to automatically slide down to the middle position without manual pushing, reducing labor intensity; as the carrier of the shearing mechanism, the rotation drives the biting plate 104 to generate shearing force, realizing the initial crushing of the iron sheet.

[0032] The two rotating plates 101 are V-shaped, allowing scrap thin iron sheets to automatically slide down their inclined surfaces to the middle position for centralized processing, thus solving the problem of scattered and difficult-to-collect small pieces of scrap iron at the source. At the same time, by utilizing the device's own crushing and compression functions, the use of containers unsuitable for holding sharp small pieces of scrap iron is avoided, reducing wear and tear on the transport vehicle during transportation and lowering transportation difficulty and costs.

[0033] The lower end of the collection box 301 is arc-shaped, and the two rotating frames 201 rotate around the axis of the collection box 301 when they rotate. This design allows the pressing mechanism to scrape the iron pieces inside the collection box 301 while it is working, ensuring that all broken and compressed iron pieces can be effectively collected, avoiding any omissions and ensuring the integrity of the recycling process.

[0034] Both rotating plates 101 are provided with guide grooves 102, and both sides of the guide grooves 102 are provided with inclined surfaces.

[0035] See Figure 3 ,

[0036] The feed chute 102 facilitates the material to slide down along the inclined surface of the rotating plate 101, preventing the material from detaching from the rotating plate 101 and moving to the outside.

[0037] The feed chute 102 is located on the rotating plate 101, and its design facilitates the sliding of materials along the inclined surface of the rotating plate 101. During the scrap iron recycling process, after the workers place the scrap iron on the rotating plate 101, the rotating plate 101 is at a certain tilt angle. The feed chute 102 utilizes this tilt angle to provide a clear downward path for the materials, allowing them to move more smoothly towards the processing area of ​​the device, which helps to improve the efficiency of the entire recycling process.

[0038] Both sides of the feed chute 102 are provided with inclined surfaces. This structure can effectively prevent materials from detaching from the rotating plate 101 and moving to the outside. During the material's descent, various factors, such as the initial placement position of the material and collisions during the descent, may cause the material to slide outwards. The inclined surfaces on both sides of the feed chute 102 can act as a barrier and guide, confining the material within the feed chute 102 and ensuring that the material always slides down the rotating plate 101 along a predetermined path, preventing the material from scattering outside the device and reducing material loss and cleaning work.

[0039] Multiple through slots 103 are provided on both rotating plates 101.

[0040] See Figure 3 ,

[0041] Multiple channels 103 serve a screening function. When the iron sheet slides off the rotating plate 101, impurities such as dust, mud, and sand mixed in with the iron sheet can be discharged through the multiple channels 103, thereby reducing impurities in the iron sheet and further improving the purity of the iron sheet.

[0042] The screening effect of the through-channel 103 reduces impurities in the iron sheets, further improving their purity. Higher iron sheet purity is crucial for subsequent iron recycling and processing. Pure iron sheets are more efficient in processes such as cleaning and smelting, reducing wear and tear on processing equipment caused by impurities, improving the quality of processed products, lowering production costs, and enhancing the overall economic benefits and quality of scrap iron recycling.

[0043] Both rotating frames 201 have material discharge ports 202 at their upper ends, and both material discharge ports 202 are located below multiple interlocking plates 104.

[0044] See Figure 6 ,

[0045] The discharge port 202 is used to discharge the broken iron pieces. The iron pieces fall into the collection box 301 through the discharge port 202. Since both discharge ports 202 are located below multiple interlocking plates 104, impurities fall onto the rotating frame 201 through multiple through slots 103. Since the rotating frame 201 rotates intermittently, it can promote the falling off of impurities under the action of vibration. The impurities automatically slide down the inclined surface on the rotating frame 201 to the gap between the rotating frame 201 and the collection box 301. The rotating frame 201 isolates the iron pieces from the impurities.

[0046] During the operation of the device, the iron pieces broken by the biting plates 104 on the rotating plate 101 need a suitable channel to enter the collection box 301 for centralized collection. The discharge port 202 provides such a dedicated channel. Located below the biting plates 104, it can accurately guide the broken iron pieces into the collection box 301, making the discharge process of broken iron pieces more orderly, avoiding random accumulation of iron pieces in the device, ensuring the rational use of the internal space of the device, and improving the smoothness of the entire recycling production process.

[0047] The pressing mechanism includes two pressing blocks 203, each of which is fixedly connected to two sliding rods 206. The two sliding rods 206 are slidably connected to the rotating frame 201. Each end of the two sliding rods 206 is fixedly connected to a baffle 207. Two springs 205 are fixedly connected between the baffle 207 and the rotating frame 201.

[0048] See Figure 6 ,

[0049] When the two rotating frames 201 approach each other, the two pressure blocks 203 contact the iron sheet, causing the two slide rods 206 to slide outwards. The two springs 205 are stretched by the force, and the two springs 205 play a buffering role to avoid affecting the rotating frame 201 and the rotating plate 101, ensuring that the rotating plate 101 can operate normally. As the number of iron sheets between the two pressure blocks 203 gradually increases, the pressure on the iron sheet increases, and it is gradually squeezed and compressed into shape.

[0050] Both slide rods 206 are slidably connected to the rotating frame 201. When the pressure block 203 contacts the iron sheet and is subjected to a reaction force, the slide rods 206 can slide outward on the rotating frame 201. This sliding design allows the pressure block 203 to move and adjust within a certain range when subjected to uneven forces or large impact forces, avoiding damage to other components caused by sudden force concentration.

[0051] Because the rotating frame 201 and the rotating plate 101 are important moving parts in the device, excessive impact could cause damage or deformation, affecting the normal operation of the device. The spring 205 provides cushioning, ensuring the normal operation of the rotating plate 101, maintaining the stability and reliability of the entire device, and extending its service life.

[0052] Both pressure blocks 203 have curved surfaces.

[0053] See Figure 5 ,

[0054] The curved surface can prevent the iron sheet from moving upwards and detaching from the two pressure blocks 203 when it is squeezed, thereby promoting the iron sheet to gather in the middle and cooperate with the collection box 301 to squeeze the iron sheet into shape.

[0055] The curved surface design conforms to mechanical principles. When the iron sheet comes into contact with the curved surface, the curved surface can wrap and constrain the iron sheet, like a fence, preventing the iron sheet from moving upwards and detaching from the two pressure blocks 203 under the pressure. This design to prevent the iron sheet from detaching ensures the continuity and stability of the pressing process, so that the iron sheet can always be in a compressed state, which is beneficial to subsequent extrusion molding operations.

[0056] The curved surface not only prevents the iron sheet from moving upwards but also promotes its aggregation towards the center. When the iron sheet comes into contact with the curved surface, its unique shape guides it towards the central area between the two pressure blocks 203. This is because the curvature of the curved surface causes the iron sheet to naturally move towards the center area where pressure is concentrated when under pressure. As the iron sheet continues to aggregate towards the center, its distribution becomes more concentrated and compact, creating favorable conditions for further extrusion molding.

[0057] The curved surface of the pressing block 203 concentrates the iron sheet in the central area, working together with the collection box 301 to ensure that the iron sheet is subjected to uniform pressure in all directions, thus gradually being compressed into a block shape. This block-shaped iron sheet is easier to transport and further process, improving the efficiency and quality of scrap iron recycling.

[0058] Multiple anti-slip protrusions 204 are provided on the arc-shaped surfaces of both pressure blocks 203.

[0059] See Figure 5 ,

[0060] Multiple anti-slip ridges 204 can further prevent the iron sheet from slipping under force, thus ensuring the compression effect on the iron sheet and making it easy to form after the iron sheet is piled up.

[0061] Multiple anti-slip ridges 204 are evenly distributed on the arc-shaped surface of the pressure block 203. These anti-slip ridges 204 increase the contact roughness between the iron sheet and the pressure block 203. When the iron sheet contacts the arc-shaped surface with the anti-slip ridges 204, the ridges embed into the surface of the iron sheet, increasing the friction between them and further preventing the iron sheet from slipping under pressure. This anti-slip effect ensures that the pressure applied by the pressure block 203 to the iron sheet is effectively transmitted to the iron sheet, allowing the iron sheet to be compressed in the intended manner.

[0062] Because the anti-slip ridges 204 prevent the iron sheet from slipping, the pressure block 203 can stably apply pressure to the iron sheet, ensuring that the pressure is evenly distributed across it. Stable pressure transmission guarantees a smooth extrusion process, allowing the iron sheet to be gradually compressed under pressure. Compared to the absence of anti-slip ridges 204, the presence of ridges prevents the iron sheet from slipping, thus ensuring a better overall extrusion effect and allowing the iron sheet to be compressed more fully.

[0063] As the iron sheets gradually clump together under the pressure of the pressing block 203, the anti-slip protrusions 204 continue to function. They help to better hold the clumped iron sheets together, preventing them from slipping or dispersing again. This allows the clumped iron sheets to continue being compressed in a relatively stable state, making it easier to form a compact block structure. The increased friction and constraint of the anti-slip protrusions 204 allow the iron sheets to be more easily shaped after clumping, ultimately forming a block-shaped iron sheet that meets the requirements, facilitating subsequent transportation and further processing.

[0064] The collection box 301 has discharge troughs 303 at both ends and a material retrieval door 302 at the bottom.

[0065] See Figure 8 ,

[0066] After the iron sheet is compressed and formed, the worker can open the material gate 302 to take out the block of iron sheet. During the rotation of the two rotating frames 201, when the two rotating frames 201 separate from each other, the two rotating frames 201 scrape the impurities on the inner wall of the collection box 301, thereby simultaneously scraping off the impurities on the inner wall of the collection box 301. The impurities are discharged through the discharge chute 303.

[0067] The movement of the rotating frame 201 simultaneously achieves the crushing, compression, and impurity removal of the iron sheet.

[0068] A drive motor 401 is fixedly connected to the collection box 301. Two eccentric wheels 402 are rotatably connected to the outer wall of the collection box 301. One of the eccentric wheels 402 is fixedly connected to the output shaft of the drive motor 401. Multiple teeth are fixedly connected to the edges of the two eccentric wheels 402. The two eccentric wheels 402 mesh and drive each other. An eccentric rod 403 is rotatably connected to each of the two eccentric wheels 402. A round rod 404 is fixedly connected to the end of each of the two eccentric rods 403. A slot frame 405 is fixedly connected to each of the two rotating plates 101. The two round rods 404 are slidably connected in the two slot frames 405 respectively.

[0069] See Figure 1-3 ,

[0070] The drive motor 401 drives one of the eccentric wheels 402 to rotate. The two eccentric wheels 402 mesh and drive each other, which in turn drives the eccentric rod 403 on the eccentric wheel 402 to push the slot frame 405. At the same time, the round rod 404 slides in the slot frame 405, thereby realizing the function of driving the two rotating plates 101 to rotate synchronously, so that the rotation amplitude and frequency of the two rotating plates 101 are the same, thereby improving the shearing effect on the iron sheet.

[0071] A method for processing scrap iron using a recycling production facility, the method comprising the following steps:

[0072] Step 1: Place the scrap thin iron sheet on the V-shaped rotating plate 101. The iron sheet will automatically slide down the inclined plane to the angle between the two rotating plates. The serrated interlocking plates 104 on the surface of the rotating plates generate shearing force through reciprocating rotation, which initially crushes the iron sheet. The crushed iron sheet falls into the collection box 301 below through the gaps in the interlocking plates.

[0073] Step 2: When the iron sheet slides down the through groove 103 on the rotating plate 101, small particles of impurities such as dust and sand pass through and fall off naturally. Iron sheets that do not pass through the through groove continue to slide down the rotating plate to the discharge port 202, ensuring that the iron sheets processed later are initially cleaned of impurities and improving their purity.

[0074] Step 3: The crushed iron pieces fall precisely into the collection box 301 through the discharge port 202. At the same time, the vibration generated by the intermittent rotation of the rotating frame 201 causes the impurities attached to it, such as small particles left during the discharge, to fall off and slide down the inclined surface of the rotating frame to the gap between the rotating frame and the collection box, thus achieving effective isolation between the iron pieces and the impurities.

[0075] Step 4: When the two rotating frames 201 approach each other, the pressure blocks 203 on them contact the iron sheets and apply pressure. The sliding rod 206 slides outward, and the spring 205 stretches to buffer, avoiding damage to the rotating plate 101. As the iron sheets accumulate, the pressure blocks continue to squeeze and compress them into a compact block shape, reducing the transport volume.

[0076] Step 5: The anti-slip protrusions 204 on the arc-shaped surface of the pressure block 203 increase the friction with the iron sheet during extrusion, preventing the iron sheet from slipping or shifting upwards under pressure and ensuring uniform pressure transmission. The clustered iron sheets are more easily and tightly bound together under the constraint of the anti-slip protrusions, ultimately forming a structurally stable block iron sheet, which facilitates subsequent processing and transportation.

4. A method for processing scrap iron using the recycling production apparatus of claim 1, characterized in that, The method includes the following steps: Step 1: Place the scrap thin iron sheet on the rotating plate. The iron sheet will automatically slide down the inclined plane to the angle between the two rotating plates. The serrated interlocking plates on the surface of the rotating plate generate shearing force through reciprocating rotation, which initially crushes the iron sheet. The crushed iron sheet falls into the collection box below through the gaps between the interlocking plates. Step 2: When the iron sheet slides down the through groove on the rotating plate, small particles of impurities such as dust and sand can pass through and fall off naturally. Iron sheets that do not pass through the through groove continue to slide down the rotating plate to the discharge port, ensuring that the iron sheets in subsequent processing are initially cleaned of impurities and improving their purity. Step 3: The crushed iron pieces fall precisely into the collection box through the discharge port. At the same time, the vibration generated by the intermittent rotation of the rotating frame causes the impurities attached to it, such as small particles left over from the discharge, to fall off and slide down the inclined surface of the rotating frame to the gap between the rotating frame and the collection box, thus effectively isolating the iron pieces from the impurities. Step 4: When the two rotating frames approach each other, the pressure blocks on them contact the iron sheets and apply pressure.

The clustered iron sheets are more likely to fit together tightly under the constraint of the anti-slip protrusions, ultimately forming a structurally stable block iron sheet, which is convenient for subsequent processing and transportation.
