Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, and more specifically, to a waste metal bolt recycling and sorting device. Background Technology

[0002] Scrap metal is an important recyclable material in the field of renewable resources, including scrap screws and bolts, metal scraps and various waste hardware parts. If such scrap metal is directly discarded and piled up, it is easy to cause rust pollution and serious waste of metal resources. Therefore, the industry generally achieves the recycling and reuse of scrap metal through centralized collection, sorting and screening, orderly transportation, secondary identification and reprocessing, so as to improve the resource recycling rate. Currently, in the industry, when recycling and processing waste screws and bolts, the waste screws and bolts that have undergone preliminary coarse screening to remove impurities are often fed into a vibrating feeder. The track conveying structure of the vibrating feeder automatically sorts the messy waste screws and bolts. As the material travels along the track, the equipment will conduct a secondary screening and judgment on the placement posture and the integrity of the shape of the screws and bolts, and select qualified materials that are regular in shape, compliant in posture and can be reused. In actual use, existing vibrating feeders often encounter problems with scrap metal (bolts, screws). Scrap metal that is misaligned, bent, warped, or damaged is removed from the conveying path at a designated location on the track and falls naturally into the lower cavity. Because scrap bolts and screws are often corroded, deformed, bent, or warped over time, and the traditional lower cavity has a narrow internal space and limited gaps, these irregularly shaped scrap materials are prone to tilting or overturning during the fall. They easily become stuck in the gaps between the side walls and corners of the lower cavity. Once stuck, the material is difficult to slide off and disperse on its own, and it is also inconvenient to manually remove it from the narrow gaps. Furthermore, the continuous accumulation of stuck material occupies the lower cavity's space, and subsequent non-compliant materials can only be piled up. If the pile height exceeds the height of the conveying track, it will interfere with the conveying of normal materials above. Therefore, a scrap metal bolt recycling and sorting device is urgently needed to solve these problems. Summary of the Invention

[0003] This invention provides a waste metal bolt recycling and sorting device. It uses a vibrating disc body in conjunction with a feeding and screening mechanism and adjustable paddles to screen waste bolts. The impact force of the falling, non-reusable waste metal bolts drives the receiving platform to vibrate and evenly distribute the material. Combined with a channel structure, this achieves automatic unloading of unqualified bolts, thereby solving the problems mentioned in the background art. When existing vibrating feeders screen waste screws and bolts, materials that are tilted, deformed, or broken fall into the narrow bottom cavity and easily get stuck in the side walls and corner gaps of the cavity, making cleaning and maintenance inconvenient and easily causing material accumulation.

[0004] To achieve the above objectives, the waste metal bolt recycling and sorting device includes a device body, which consists of a vibrating feeding device and an outer frame installed around the vibrating feeding device. Its features are as follows: The vibrating feeding device includes a vibrating disc body, a material cavity is formed between the outer frame and the outer wall of the vibrating disc body, a feeding and screening mechanism is connected to the opening of the vibrating disc body, the feeding and screening mechanism is used to screen the scrap metal bolts by state, and a receiving assembly is movably installed in the middle of the material cavity, the receiving assembly includes a receiving platform. When scrap metal bolts with different shapes are screened and peeled off by the feeding and screening mechanism, the receiving platform can collect the scrap metal bolts. At the same time, the gravity of the scrap metal bolts falling puts pressure on the receiving platform, causing the receiving platform to vibrate vertically inside the material cavity. The vibration of the receiving platform can make the scrap metal bolts evenly placed inside the receiving platform and help the scrap metal bolts slide out from the side opening of the material cavity.

[0005] In the above technical solution, a vibrating plate body is used in combination with a feeding and screening mechanism to screen the posture and shape of the scrap metal bolts. At the same time, the weight of the unqualified material falling drives the receiving platform to generate passive vertical vibration, which helps the scrap metal bolts to be evenly distributed in the material cavity, and works with the receiving component to automatically discharge the scrap metal bolts.

[0006] Based on this, the vibratory feeding device also includes a support frame, which is used to support the vibratory plate body, and the vibratory plate body has a spiral inner groove formed inside.

[0007] Furthermore, the feeding and screening mechanism includes a screening platform that is connected to the top opening of the vibrating plate body, and a material sliding track is connected to one end of the screening platform away from the connection point of the vibrating plate body. An adjustment groove is provided inside the screening table on the side near the material sliding track. A lever is movably installed in the adjustment groove. By changing the height of the lever, the gap between the lever and the screening table can be adjusted so that the gap matches the reusable size of the scrap metal bolts.

[0008] The vibratory feeder body is stably supported by a support frame. The vibratory feeder body is equipped with a spiral groove inside, which can realize the orderly spiral feeding of waste metal bolts. At the same time, the screening table connects the vibratory feeder body and the sliding track to form a continuous conveying path. With the adjustable groove and the movable paddle, it can adapt to the screening needs of different specifications of reusable waste metal bolts, and realize the sorting and identification of material posture and size.

[0009] In another technical solution, the receiving assembly further includes a support member installed in the material cavity. The receiving platform is supported in the material cavity by the support member. The surface of the receiving platform is provided with a channel, and the inner diameter of the channel is slightly larger than the inner diameter of the material sliding track.

[0010] Preferably, the support includes a fixed tube, the bottom end of which is fixedly connected to the bottom of the inner cavity of the material chamber. The fixed tube has a hollow structure, and an inner support tube is slidably provided inside the fixed tube. The side of the inner support tube away from the fixed tube is fixedly installed at the bottom of the receiving platform. An elastic element is fixedly connected to one end of the inner support tube near the fixed tube, and the other end of the elastic element is installed inside the fixed tube. A gap is left between the periphery of the receiving platform and the inner wall of the material cavity, so that the receiving platform can be vertically adjusted in the material cavity.

[0011] This technical solution uses a retractable and buffered support to flexibly support the receiving platform. At the same time, it utilizes the pre-reserved gap between the receiving platform and the inner wall of the material cavity to ensure that the receiving platform can smoothly achieve vertical reciprocating movement within the material cavity. While receiving fallen scrap metal bolts, it can also use the deformation and reset of the elastic element to achieve passive vibration and material uniformity, guiding the material to slide out in a directional manner.

[0012] As a further improvement to this technical solution, the inner wall of the channel is covered with a coating film, which is used to assist the sliding transport of scrap metal bolts inside the channel. The top surface of the receiving platform is inclined, and the side of the receiving platform near the opening of the outer frame is lower than the other side of the receiving platform. The top cross-section of the receiving platform has a wavy structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this waste metal bolt recycling and sorting device, by setting up a feeding and screening mechanism in conjunction with the vibrating plate body, the waste metal bolts are conveyed to the screening table through the vibrating plate body. By using the adjustable height lever in the adjustment groove, the screening gap can be adjusted according to the reusable size of the waste metal bolts, and the bolts can be screened and sorted according to their placement posture and shape. Qualified waste metal bolts can be continuously conveyed and transferred via the sliding track. 2. In this waste metal bolt recycling and sorting device, when non-compliant waste metal bolts are peeled off from the screening table by the pry bar, they can fall directly into the material chamber and onto the receiving platform. The waste metal bolts rely on their own weight and the impact force of falling to press down on the receiving platform, which drives the inner support tube to compress the elastic element to realize the vertical reciprocating vibration of the receiving platform in the material chamber. The vibration disrupts the stacked state of the waste bolts, so that the material is evenly distributed on the receiving platform. At the same time, the receiving platform has an inclined wave-shaped structure. With the smooth assistance of the surface channel and the coating film, the vibration can guide the waste bolts to slide into the channel. Through the height difference of the channel and the weight of the waste metal bolts themselves, they slide out from the side opening of the material chamber for unloading.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] When existing vibrating feeders convey and screen scrap metal bolts, the materials in the vibrating plate are piled up in a disorderly manner. In addition, the scrap bolts are of different shapes and specifications. During the feeding vibration process, the workpieces are squeezed and offset from each other, and the arrangement is misaligned. Some bolts cannot travel in a regular manner along the predetermined track and fall from the screening gap or material gap into the bottom cavity of the equipment. After long-term use, scrap metal bolts often have irregular shapes such as rust, compression bending, and end face warping. In addition, the internal space of the bottom cavity is small and the gaps are narrow. When deformed materials fall, they are prone to tilting and overturning. They are easy to get stuck in the gaps of the bottom cavity side wall and corner gaps. This not only makes cleaning and maintenance inconvenient, but also makes it easy for materials to accumulate and interfere with normal screening and conveying. In view of this, see Figures 1-4 As shown, the present invention provides a waste metal bolt recycling and sorting device, including a device body 1. The device body 1 is composed of a vibrating feeding device 2 and an outer frame 11 installed around the vibrating feeding device 2. The vibrating feeding device 2 includes a vibrating disc body 21. A material cavity 12 is formed between the outer frame 11 and the outer wall of the vibrating disc body 21 for collecting waste metal bolts that have been screened and rejected. The opening of the vibratory feeder body 21 is connected to the feeding and screening mechanism 3, which is used to screen the scrap metal bolts according to their state. The middle of the material chamber 12 is movably installed with the receiving assembly 4, and the movable installation structure is a vertical reciprocating vibration of the receiving platform 42 with reserved space for movement. The receiving assembly 4 includes a receiving platform 42. When scrap metal bolts of different shapes are screened and peeled off by the feeding and screening mechanism 3, the receiving platform 42 can receive the scrap metal bolts. At the same time, the weight of the scrap metal bolts falling puts pressure on the receiving platform 42, causing the receiving platform 42 to generate vertical vibration inside the material cavity 12. The passive vibration is triggered by the weight of the material itself. The vibration of the receiving platform 42 can make the scrap metal bolts evenly placed inside the receiving platform 42, effectively reducing the situation of scrap bolts accumulating locally in the material cavity 12 or getting stuck in the narrow gap of the material cavity 12.

[0018] Furthermore, the vibrating feeding device 2 also includes a support frame 22 and a spiral inner groove 23, such as Figure 1As shown, the top of the support frame 22 is fixedly connected to the bottom of the vibratory plate body 21, which is used to provide stable support and positioning for the vibratory plate body 21. The vibratory plate body 21 has an integrally formed inner groove 23 in a spiral upward shape along its inner wall. The spiral trajectory of the inner groove 23 extends from the bottom of the vibratory plate body 21 to its top opening, which is used to carry the waste metal bolts to be processed and guide them to move in an orderly manner.

[0019] During operation, after the vibratory feeding device 2 is started, the vibration energy is transmitted through the inner wall of the vibratory plate body 21 to the spiral inner groove 23 inside it. Under the vibration of the vibratory plate body 21, the scrap metal bolts gradually enter the spiral inner groove 23. Under the continuous action of vibration, the scrap metal bolts slowly rise along the spiral trajectory of the spiral inner groove 23. During the rising process, the spiral inner groove 23 limits the scrap metal bolts, allowing the bolts to move orderly along the direction of the inner groove 23. As the vibration continues, the scrap metal bolts continue to rise along the spiral inner groove 23 and are finally discharged from the top opening of the vibratory plate body 21, directly entering the feeding and screening mechanism 3 connected to it, completing the feeding and conveying process of scrap metal bolts. During the entire operation, the support frame 22 maintains stable support for the vibratory plate body 21, ensuring the operational stability of the vibratory plate body 21 and the spiral inner groove 23.

[0020] See Figure 2 and combined Figure 3 As shown, the feeding and screening mechanism 3 includes a screening table 31, which has an overall arc-shaped structure. One end of the screening table 31 is connected to the top opening of the vibrating plate body 21, allowing it to receive scrap metal bolts conveyed from the vibrating plate body 21. The end of the screening table 31 away from the vibrating plate body 21 is fixedly connected to the sliding track 32, which is inclined and used to convey the qualified scrap metal bolts to the next process. To achieve flexible adjustment of the screening gap, the screening table 31 is positioned closer to the sliding track 32. A rectangular adjustment groove 311 is provided on one side. The adjustment groove 311 extends along the width of the screening table 31. The paddle 33 is movably embedded in the adjustment groove 311. The bottom end of the paddle 33 corresponds to the table surface of the screening table 31. By adjusting the installation height of the paddle 33 in the adjustment groove 311, the gap between the bottom end of the paddle 33 and the table surface of the screening table 31 can be changed. The size of this gap can be adapted and adjusted according to the reusable size of the scrap metal bolts to ensure the targeted screening operation.

[0021] After the vibratory feeder body 21 starts operating, the scrap metal bolts rise along the spiral inner groove 23 and are discharged from its top opening. They then directly enter the screening table 31 connected to it. Under the vibration transmission of the vibratory feeder body 21, the scrap metal bolts gradually and smoothly move towards the sliding track 32 on the screening table 31. Before the scrap metal bolts move to the end of the screening table 31 near the sliding track 32, the operator can pre-adjust the height of the lever 33 in the adjusting groove 311 according to the reusable size of the scrap metal bolts to be screened, so that the gap between the lever 33 and the screening table 31 matches the size of the reusable scrap metal bolts. Figure 5 As shown, during operation, the reusable scrap metal bolts are in a regular shape, without obvious bending or warping, and their size meets the reusability standard. They can directly pass through the gap between the lever 33 and the screening table 31 and continue to move towards the sliding track 32. Combined again Figure 5 The portion of the waste bolt that is too large in shape, has obvious bending, warping or deformation, and cannot meet the requirements for reuse in terms of shape, is larger than the gap between the paddle 33 and the screening table 31 and cannot pass through the gap. During continuous movement, it will come into contact with the side of the paddle 33. Under its own moving inertia and the blocking effect of the paddle 33, it will be peeled off from the screening table 31 by the paddle 33. The peeled waste bolt falls from the edge of the screening table 31 and enters the material cavity 12 below.

[0022] It should be noted that during the sliding movement of normal-sized scrap metal bolts on the screening table 31, due to the limitations of their own shape and structure, their top ends do not have the support conditions to maintain the vertical sliding posture of the bolts. As a result, the bolts always remain in a flat sliding state. After adjusting the installation height of the lever 33 according to the reusable size, the overall height of the normal bolts in the flat state is lower than the lower edge of the lever 33, and they can pass smoothly through the gap between the lever 33 and the screening table 31.

[0023] like Figure 6As shown, the paddle 33 can be adjusted in height within the adjustment groove 311. Specifically, the adjustment groove 311 is a rectangular recess inside the screening table 31, with symmetrically arranged vertically extending guide grooves on its inner walls (its installation structure uses existing technology and is not shown in the figure). The length of the guide groove is adapted to the preset adjustment stroke of the paddle 33. The cross-section of the guide groove is T-shaped. The paddle 33 is a rectangular sheet structure, with T-shaped guide blocks integrally formed on both sides corresponding to the guide groove positions. The T-shaped guide blocks match the T-shaped guide groove, and can be embedded inside the guide groove and slide vertically along it. Through the cooperation of the guide blocks and the guide groove, the paddle 33 can be adjusted in height within the adjustment groove 311. The guide limit within 11 ensures that the paddle 33 can only move vertically. A horizontally positioned adjustment seat is fixedly installed on the inner wall of the top of the adjustment groove 311. A vertically penetrating threaded hole is opened in the middle of the adjustment seat. An adjustment bolt is threaded into the threaded hole. The top of the adjustment bolt extends to the outside of the screening table 31 and is fixedly connected to an adjustment knob. After the bottom end of the adjustment bolt passes through the threaded hole, it is rotatably connected to the top middle of the paddle 33 through a deep groove ball bearing. The inner ring of the deep groove ball bearing is fixedly sleeved with the bottom end of the adjustment bolt, and the outer ring is fixedly embedded in the mounting groove opened at the top of the paddle 33. This allows the paddle 33 to move vertically when the adjustment bolt rotates, without causing the paddle 33 to rotate synchronously. When the gap needs to be adjusted, the operator turns the adjustment knob, which moves the adjustment bolt vertically along the threaded hole. The adjustment bolt drives the paddle 33 to move vertically along the guide groove through the deep groove ball bearing, thereby changing the gap between the bottom end of the paddle 33 and the surface of the screening table 31. After the adjustment is completed, the self-locking action of the threaded bolt and the threaded hole can fix the position of the paddle 33, ensuring that the gap remains stable during the screening process.

[0024] Further reading Figures 7-9 As shown, after the paddle 33 separates the non-compliant scrap metal bolts, the scrap metal bolts fall into the material cavity 12. At this time, the receiving assembly 4 located in the material cavity 12 can receive the scrap metal bolts. Specifically, the receiving assembly 4 includes a support member 41 set inside the material cavity 12. The support member 41 is composed of a fixed tube 411, an inner support tube 412, and an elastic member 413 (preferably a spiral spring). The bottom end of the hollow fixed tube 411 is fixedly connected to the bottom of the inner cavity of the material cavity 12. The inner support tube 412 is slidably assembled inside the fixed tube 411. The upper end of the inner support tube 412 is fixedly connected to the bottom of the receiving platform 42. The lower end of the inner support tube 412 is connected to the bottom of the inner cavity of the fixed tube 411 through the elastic member 413. A movable gap is left between the periphery of the receiving platform 42 and the inner wall of the material cavity 12, so that the receiving platform 42 can be vertically adjusted inside the material cavity 12. Figure 10As shown, the receiving platform 42 has a channel 43 on its surface. The inner diameter of the channel 43 is slightly larger than the inner diameter of the material sliding track 32. The inner wall of the channel 43 is covered with a coating film 44. The top surface of the receiving platform 42 is an inclined slope, and the side closer to the opening of the outer frame 11 is lower.

[0025] During operation, the scrap metal bolts that have been screened and stripped by the feeding and screening mechanism 3 fall freely to the top surface of the receiving platform 42. The weight of the scrap metal bolts and the impact force of falling act on the receiving platform 42, causing the receiving platform 42 to move downward. Simultaneously, the inner support tube 412 slides downward along the inner cavity of the fixed tube 411 and compresses the elastic element 413. After being compressed and storing energy, the elastic element 413 generates a rebound force, pushing the inner support tube 412 and the receiving platform 42 to reset upward. This cycle forms the vertical reciprocating micro-motion of the receiving platform 42 in the material cavity 12.

[0026] During the vibration of the receiving platform 42, the scrap metal bolts on the top surface with different postures slide and adjust their postures as the platform moves. Some scrap metal bolts will slide into the interior of the channel 43. The coating film 44 on the inner wall of the channel 43 can reduce the contact friction between the bolts and the inner wall of the channel 43. The inclined structure of the receiving platform 42 forms a natural height difference. The scrap metal bolts rely on their own weight to slide smoothly along the channel 43. Finally, they can slide out of the material cavity 12 from the side opening of the outer frame 11, completing the process of receiving, dispersing and automatically discharging unqualified scrap metal bolts.

[0027] The aforementioned coating film 44 can be made of ultra-high molecular weight polyethylene wear-resistant lubricating film material. This material has the characteristics of low surface friction coefficient, resistance to metal impact and wear, and resistance to rust adhesion, making it suitable for working environments where scrap metal bolts slide in contact for a long time.

[0028] In actual processing, scrap metal bolts fall onto the surface of the receiving platform 42 in various positions. The top section of the receiving platform 42 adopts a wave-shaped structure design. The concave and convex curved surface of the wave can provide multi-point support and limit the scrap metal bolts falling in different positions, changing the force fulcrum and placement angle of the vertical scrap metal bolts, so that the bolts tend to lie flat or be placed on their sides in a regular shape. At the same time, the side of the receiving platform 42 near the side opening of the outer frame 11 is set as a low position arrangement, forming a unidirectional inclined slope. The height difference of the slope can guide the material on the platform to slide naturally towards the side opening, forming a directional flow path in conjunction with the channel 43, which is suitable for the subsequent collection and transportation of scrap metal bolts.

[0029] Working principle: First, the waste metal bolts to be recycled are placed into the vibratory feeder body 21. The vibratory feeding device 2 is started and running. The vibratory feeder body 21 vibrates and transmits the vibration energy to the spiral inner groove 23 inside it. Under the action of vibration, the waste metal bolts gradually enter the spiral inner groove 23 and move and are conveyed in an orderly manner along the spiral upward trajectory of the spiral inner groove 23. After being discharged from the top opening of the vibratory feeder body 21, they smoothly enter the screening table 31 that is connected to it. According to the actual size of the reusable scrap metal bolts, the operator adjusts the installation height of the lever 33 in the adjustment groove 311. Under the action of vibration transmission, the scrap metal bolts slide smoothly on the screen table 31 towards the sliding track 32. Scrap metal bolts of normal specifications cannot maintain a vertical sliding posture due to their own shape and structure, and remain in a horizontal position. The overall height of the horizontal position is lower than the height of the lower edge of the lever 33, so it can pass through the screening gap smoothly and be transported to the subsequent operation process along the sliding track 32. Scrap metal bolts whose shape has been deformed and whose size exceeds the screening gap will contact the side wall of the lever 33 during the movement. Under the action of their own movement inertia and the blocking effect of the lever 33, they will peel off from the edge of the screen table 31 and fall into the material cavity 12. The fallen scrap metal bolts land on the top surface of the receiving platform 42, which is movable in the middle of the material cavity 12. They press down on the receiving platform 42 by their own weight and the impact force of falling, causing the inner support tube 412 to slide along the inside of the fixed tube 411 and compress the elastic element 413. After the elastic element 413 is compressed and stores energy, it rebounds and resets, causing the receiving platform 42 to make vertical reciprocating micro-movements within the reserved gap range of the material cavity 12. At the same time, the wave-shaped cross-section structure at the top of the receiving platform 42 provides multi-point support for scrap metal bolts with different falling postures, adjusting the bolt placement angle to a flat or side-lying and neat state. The receiving platform 42 is set at a low position near the side opening of the outer frame 11 to form an inclined slope, guiding the scrap metal bolts to slide towards the platform channel 43. The scrap metal bolts move smoothly along the channel 43 with the help of the slope difference and their own weight, and slide out of the material cavity 12 from the side opening of the outer frame 11, completing the receiving, evenly distributing and automatic discharge of unqualified scrap metal bolts.
