Description

Technical Field

[0001] This invention relates to the field of power material recycling equipment technology, specifically to an automated sorting device and method for cable scraps. Background Technology

[0002] Waste electrical materials contain a large amount of reusable metal resources, especially copper and aluminum in cables and steel-cored aluminum stranded wires. Recycling and reusing these materials can not only save raw materials but also reduce production costs and achieve effective recycling of resources.

[0003] For automated decomposition production lines of steel-cored aluminum stranded wire, some incompletely crushed materials are easily generated during the crushing process due to factors such as tool wear. Incompletely crushed materials flowing into the next process can cause problems such as blockage of the material flow line and reduced purity of sorted products. This not only affects the efficiency of the production line, but also often requires manual intervention to screen the crushed materials.

[0004] Patent publication number "CN214918026U" discloses a vibrating screen with a vibrating motor for primary material sorting, including a vibrating screen bucket assembly and a base. The vibrating screen bucket assembly includes a vibrating screen bucket, a feeding platform, guide ribs, and a secondary step. A small particle collection port is provided at the left front end of the vibrating screen bucket. Baffle plates are fixedly connected to both sides of the vibrating screen bucket. A mounting base is fixedly connected to the lower end face of the vibrating screen bucket. The mounting base and the base are connected by elastic components. A rejection system assembly is provided inside the vibrating screen bucket. The elastic components of this patent consist of springs and rubber pads. The rubber pads at the ends of the springs reduce noise. However, the springs have low resistance, large deformation, poor anti-lateral deviation performance, and the elastic coefficient decreases after long-term use, resulting in a short service life.

[0024] In another aspect, the present invention provides an automatic sorting method for cable scraps, using the automatic sorting device for cable scraps provided by the present invention, wherein the sorting method includes, Place the scrap material to be sorted onto the container; The vibration of the drive housing relative to the support frame is reduced and noise is decreased when the housing is supported by a composite spring. When screening by step-type vibrating screen, the screening residence time of the crushed material is extended. The arc surface of the screen bar guides the crushed material to be sorted to adjust its posture to the lateral direction for sorting. The guide plate guides the broken material falling through the discharge chamber to the discharge port.

[0025] According to the present invention, an automatic sorting method for cable scraps includes a step-type vibrating screen for layered screening. When the vibrating screen vibrates, the material is transported from the front-opening discharge chamber to the next screen unit through the vibration.

[0026] The beneficial effects of this invention include: 1. The box body is installed on the support frame through the connecting assembly. The connecting assembly flexibly supports the box body through composite springs. The rubber block of the connecting assembly has embedded metal springs, which can increase the deformation damping of conventional metal springs, reduce deformation, improve anti-lateral deviation performance, reduce the vibration amplitude of the box body, extend the service life, and also have a noise reduction effect. When the box body vibrates, it drives the vibrating screen to vibrate. The vibrating screen is high at one end and low at the other end. When vibrating, the broken material moves from the high end to the low end and falls from the material drop chamber. It is guided to the discharge port by the guide plate. The broken material that is not screened on the vibrating screen is collected at the low end of the vibrating screen, which is convenient for automated collection and avoids the accumulation of broken material on the vibrating screen. It can achieve continuous screening when effectively separating incompletely broken material. 2. The multiple screen units of the vibrating screen are arranged in a stepped manner, which can screen the crushed material in layers. This avoids clogging of the crushed material and appropriately extends the screening time, improving the screening accuracy. It also avoids the problems of the entire screen surface being tilted, which leads to too short a screening time, and the entire screen surface being at the same height, which leads to excessive material accumulation and screening time. 3. The screen unit has a clever structural design. Multiple screen bars are installed at intervals through the installation beams. The gaps between the screen bars form a material drop chamber. During vibration screening, the arc surface of the screen bar guides the strip-shaped fragments to be sorted to change their posture and adjust them to be transverse, so that they can fall from the material drop chamber, thereby improving screening efficiency. Incompletely crushed fragments are intercepted and transported to the next screen unit. 4. The screen unit is inclined with the front end lower and the rear end higher, with an angle α of 4-15° to the horizontal plane. This allows for adjustment of the screening time, avoiding material accumulation due to excessive time and poor screening accuracy due to insufficient time. Multiple screen bars are connected to the longitudinal mounting beam, making the front end of the gap between adjacent screen bars open. This facilitates the transport of incompletely crushed material from the front opening of the drop chamber to the next screen unit through vibration when it gets stuck, significantly improving the problem of material sticking. 5. The connecting components are mounted on the housing via connecting seats and connected to the support frame via composite springs, ensuring the connection strength between the housing and the support frame while allowing relative movement to facilitate housing vibration; 6. Support shafts are provided on both sides of the housing. The connecting seat provides a composite spring for connecting the base. The support shaft is installed through the receiving hole between the base and the cover plate. Tightening the cover plate can connect the support shaft into the receiving hole. The tightness is adjustable and the installation is convenient. 7. The support frame supports the box body through the column. The composite spring has insertion holes at both ends. The connecting seat is inserted into the insertion holes at both ends of the composite spring through the protrusion on the opposite side of the column. This installation method allows the box body to move up and down and the metal spring to swing radially. The connection is simple and reliable. 8. The box body receives the crushed material from the receiving plate and limits the crushed material by the side plates on both sides. The crushed material falling through the discharge chamber is guided by the inclined guide plate and collected at the discharge port to facilitate the automated sorting of crushed material. 9. The vibratory motor is installed on the box as the driving force, causing the box to vibrate relative to the support frame, which is convenient to use; 10. The automated sorting method for cable scrap provided by this invention fully utilizes the structural characteristics of the automated sorting device for cable scrap provided by this invention. It uses composite springs for vibration reduction and noise reduction, improves mechanical strength and durability, and uses a stepped vibrating screen for layered screening. It maintains a certain screening time. The high end of the vibrating screen and the low end of the screen can avoid material accumulation. The arc surface of the screen bar guides the scrap to change its posture to lateral, which facilitates the falling of completely crushed strip scraps and sorts out the incompletely crushed scraps. The scraps falling through the discharge chamber are guided by the guide plate to the discharge port, which facilitates automated centralized collection and realizes automated continuous sorting of scraps.

[0027] This invention provides an automated sorting device for cable scraps. The housing is connected to the support frame by a composite spring and can vibrate relative to it. By embedding metal springs in rubber blocks, the problem of low moving resistance and poor anti-lateral deviation performance of conventional metal springs is improved. The vibrating screen is installed on the housing with one end higher and the other end lower. The scraps are sorted through the discharge chamber. The scraps falling from the discharge chamber are guided to the discharge port by the guide plate on the lower side of the housing. It is easy to use and has great promotional value.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] This invention relates to an automated sorting device for cable scraps, used for sorting scraps during cable recycling. A housing 3 is mounted on a support frame 1 via a connecting assembly 2. The connecting assembly 2 flexibly supports the housing 3 via a composite spring 21. A metal spring is embedded in the rubber block of the connecting assembly 2, which increases the deformation damping of conventional metal springs, reduces deformation, improves anti-lateral deviation performance, reduces the vibration amplitude of the housing 3, extends its service life, and also has a noise reduction effect. When the housing 3 vibrates, it drives the vibrating screen 4 to vibrate. The vibrating screen 4 has one high end and the other low end. During vibration, the scraps move from the high end to the low end and fall from the discharge chamber, being guided by the guide plate 311 to the discharge port 312. The scraps that are not screened off on the vibrating screen 4 are collected at the low end of the vibrating screen 4 for automated collection, preventing scraps from accumulating on the vibrating screen 4 and achieving continuous screening of incompletely broken scraps.

[0034] An automated sorting device for cable scraps, specifically, such as... Figure 1-13 As shown, the device includes a support frame 1, a connecting assembly 2, a housing 3, and a vibrating screen 4. The housing 3 is movably connected to the support frame 1 via multiple connecting assemblies 2 for vibration relative to the support frame 1. The housing 3 has an opening on the upper side and a discharge port 312 at one end of the lower side. The housing 3 includes a guide plate 311 located on the lower side for guiding the sorted crushed material (crushed material falling through the discharge chamber of the vibrating screen 4) to the discharge port 312. The connecting assembly 2 includes a composite spring 21 fixed on the support frame 1. The composite spring 21 includes a rubber block and a metal spring embedded in the rubber block. The vibrating screen 4 is located at the opening on the upper side of the housing 3 with one end higher and the other end lower. The vibrating screen 4 has multiple discharge chambers. The housing 3 is provided with flexible support by the composite spring 21 of the connecting component 2. The rubber block of the composite spring 21 can increase the deformation resistance of the metal spring, increase the elastic coefficient, reduce the deformation, protect the metal spring, extend the service life, and reduce the noise generated during vibration. The vibrating screen 4 is set with one end high and the other end low. During vibration, part of the crushed material falls through the discharge chamber and is then guided to the discharge port 312 by the guide plate 311. The other part of the crushed material is transported from the high end to the low end when the vibrating screen 4 vibrates, avoiding crushed material blockage, facilitating automated collection, and enabling continuous automated operation.

[0035] In one implementation scheme, such as Figure 1 and Figure 3As shown, the vibrating screen 4 includes multiple screen body units 41, which are mounted on the housing 3 in a stepped configuration. The front end of each screen body unit 41 (in the direction of material transport, shown on the right side of the diagram) is positioned above the rear end of the adjacent lower screen body unit 41 to prevent material from falling between adjacent screen body units 41. Each screen body unit 41 has multiple material discharge chambers. The stepped arrangement of the multiple screen body units 41 in the vibrating screen 4 allows for layered screening of material, preventing material blockage while appropriately extending the screening time and improving screening accuracy. This avoids problems such as excessively short screening time due to screen surface inclination and excessively long screening time due to the entire screen surface being at the same height.

[0036] During the crushing and dismantling process of steel-cored aluminum stranded wire, incomplete material decomposition is common. Furthermore, the crushed material is often characterized by long and curved segments. The incompletely crushed fragments are in a curved state, and conventional screens cannot effectively separate the incompletely crushed material.

[0037] The vibrating screen 4 includes multiple screen body units 41, such as Figure 5-6 As shown, the screen unit 41 includes a mounting beam 411 and multiple screen rods 412. The multiple screen rods 412 are spaced apart on the mounting beam 411 along its length to form a rod-type screen. The gap between adjacent screen rods 412 forms a material drop chamber. The side of the screen rod 412 that receives the crushed material is an arc-shaped surface. The screen unit 41 has an ingenious structural design. Multiple screen rods 412 are installed at intervals through the mounting beam 411, and the gap between the screen rods 412 forms a material drop chamber. During the vibrating screen 4, the arc-shaped surface of the screen rods 412 guides the strip-shaped crushed material to be sorted to change its posture and adjust it to be transverse, so that it can fall into the material drop chamber more easily, thus improving the screening efficiency. Curved crushed material cannot pass through the gap between the screen rods 412, and incompletely crushed crushed material can be intercepted and transported to the next screen unit 41.

[0038] The vibrating screen 4 includes multiple screen body units 41, such as Figure 7 As shown, the screen body unit 41 (screen surface) is installed at an angle on the box 3 with the front end lower and the rear end higher, and the angle α with the horizontal plane is 4-15°, including any angle between 4°, 5°, 6.5°, 8°, 10°, 13°, and 15°. This can be understood as the screen rod 412 having the front end lower and the rear end higher, and the angle α between the screen rod 412 and the horizontal plane being 4-15°. In actual installation, the screen rods 412 can be evenly fixed to the mounting beam 411 along the length of the mounting beam 411 to form the screen body unit 41. When installing the mounting beam 411 onto the box 3, the angle α between the screen rods 412 and the horizontal plane can be adjusted to 4-15°. The screening time can be adjusted to avoid material accumulation due to excessive time and poor screening accuracy due to insufficient time.

[0039] The screen unit 41 includes a mounting beam 411 and multiple screen bars 412, such as Figure 5-6 As shown, the mounting beam 411 is longitudinally arranged on the box body 3, and multiple screen bars 412 are transversely connected to the mounting beam 411 and extend forward, making the material discharge chamber a strip-shaped chamber with an open front end. By connecting multiple screen bars 412 transversely to the longitudinal mounting beam 411, the front ends of the gaps between adjacent screen bars 412 are open, which facilitates the transport of incompletely crushed fragments from the front-opening material discharge chamber to the next screen unit 41 through vibration when they are stuck, significantly improving the problem of material sticking.

[0040] In one embodiment, the mounting beam 411 abuts against the screen rod 412 of the adjacent upper screen unit 41, or the vertical distance between the mounting beam 411 and the screen rod 412 of the adjacent upper screen unit 41 is less than the size of the broken material, so as to prevent the broken material from falling from the vertical gap between the mounting beam 411 and the front end of the screen rod 412 of the upper screen unit 41.

[0041] In some implementations, such as Figure 2 , Figure 8-11 As shown, the connecting component 2 also includes a connecting seat 22, which is installed on the housing 3. The top and bottom ends of the composite spring 21 are connected to the connecting seat 22 and the support frame 1 respectively, ensuring the connection strength between the housing 3 and the support frame 1 while allowing relative movement, which facilitates the vibration of the housing 3.

[0042] The connection component 2 also includes a connector 22, such as Figure 2 , Figure 8-10 As shown, the housing 3 has side-extending support shafts 36 on both sides; the connecting seat 22 includes a base 221 and a cover plate 222 movably mounted on the base 221. A receiving hole 223 is provided between the base 221 and the cover plate 222. The cover plate 222 is used to adjust the size of the receiving hole 223 to clamp the support shaft 36. The connecting seat 22 provides a composite spring 21 connected to the base 221. The support shaft 36 is installed through the receiving hole 223 between the connecting seat 221 and the cover plate 222. Pressing the cover plate 222 can connect the support shaft 36 into the receiving hole 223. The tightness is adjustable, and the installation is convenient.

[0043] The connecting seat 22 includes a base 221 and a cover plate 222 movably disposed on the base 221, such as Figure 9-10 As shown, both the cover plate 222 and the base 221 have arc-shaped grooves on their opposing sides. The cover plate 222 is bolted to the base 221, connecting the two arc-shaped grooves to form a receiving hole 223. The bolted connection of the cover plate 222 to the base 221 facilitates adjustment of the size of the receiving hole 223. In addition, a noise-reducing sleeve can be fitted over the support shaft 36 to reduce frictional noise between the support shaft 36 and the receiving hole 223.

[0044] The connection component 2 also includes a connector 22, such as Figure 1-2As shown in Figures 8 and 11, the support frame 1 includes multiple columns 11 for supporting the housing 3. The connecting seat 22 and the top of the columns 11 have opposing protrusions 23 with gaps, meaning there is a gap between the bottom protrusion 23 of the connecting seat 22 and the top protrusion 23 of the column 11. The rubber block of the composite spring 21 has insertion holes for the coupling protrusions 23 at both ends. The two ends of the composite spring 21 are inserted into the protrusions 23 on both sides, with the top and bottom surfaces respectively abutting the bottom surface of the connecting seat 22 and the top surface of the column 11. The protrusions 23 with gaps on both sides are inserted into the insertion holes at both ends, giving the composite spring 21 a certain radial bending performance, facilitating the transmission of debris during vibration. The support frame 1 supports the housing 3 through the columns 11. The composite spring 21 has insertion holes at both ends, and the protrusions 23 on the opposing sides of the connecting seat 22 and the columns 11 are inserted into the insertion holes at both ends of the composite spring 21. This installation method allows the housing 3 to move up and down and the metal spring to swing radially, making the connection simple and reliable.

[0045] In one implementation scheme, such as Figure 11 As shown, a mounting plate 113 is fixedly connected to the top of the column 11. A protrusion 23 is fixedly provided on the mounting plate 113. The two ends of the composite spring 21 are sleeved on the protrusion 23, and the top and bottom end faces respectively abut against the bottom surface of the connecting seat 22 and the top surface of the mounting plate 113.

[0046] In a specific implementation plan, such as Figure 8 As shown, the bottom of the connecting seat 22 and the top of the column 11 are provided with multiple pairs of protrusions 23 (two corresponding protrusions 23 are a pair). The top and bottom ends of multiple composite springs 21 are sleeved on multiple pairs of protrusions 23, which together support a connecting seat 22, which can improve the flexible connection strength, reduce the pressure of a single composite spring 21, and extend the service life.

[0047] Based on the support frame 1, which includes multiple columns 11, such as Figure 2 As shown, the column 11 includes a front column 111 and a rear column 112 spaced apart. The front column 111 and the rear column 112 are located on both sides of the box body 3 and are connected by a connecting beam 12. Angle plates 13 are installed at the connection between the connecting beam 12 and the front column 111 and / or the rear column 112. The front column 111 is shorter than the rear column 112, so that the box body 3 is installed on multiple columns 11 through the connecting assembly 2 in an inclined state with the front end lower and the rear end higher, which facilitates the installation of the vibrating screen 4 with the front end lower and the rear end higher on the box body 3.

[0048] In one implementation scheme, such as Figure 12-13As shown, the box body 3 includes a bottom plate 31 and side plates 32 connected to both sides of the bottom plate 31, so that an opening is formed on the upper side of the box body 3. The bottom plate 31 is inclined with the front end higher and the rear end lower. The side plates 32 connected to the vibrating screen 4 with one end higher and the other end lower are located at the upper opening. The front part of the bottom plate 31 gradually approaches the front part of the vibrating screen 4. It can be composed of multiple bottom plates. The bottom plate 31 can be a guide plate 311. It can be understood that the bottom plate 31 is a guide plate 311. The lower end (front end) of the bottom plate 31 is provided with a discharge port 312.

[0049] In another embodiment (not shown in the figure), the guide plate 311 is not the bottom plate 31 of the box. The guide plate 311 is inclined on the box body 3 and located below the vibrating screen 4. In this embodiment, the bottom plate 31 of the box body 3 may not be inclined.

[0050] In a specific implementation plan, such as Figure 12-13 As shown, the housing 3 also includes a receiving plate 34 located at the rear end of the upper opening, which is used to receive broken materials. The receiving plate 34 can be inclined with the front end lower and the rear end higher, or it can be set horizontally. The housing 3 is provided with baffle plates 33 on both sides. The baffle plates 33 are set on the side plates 32 and the receiving plate 34 to limit the broken materials and prevent them from jumping out of the housing 3 when vibrating. A discharge plate 35 (upper discharge position) is fixed between the two side plates 32. The discharge plate 35 can be inclined and is located at the front end of the vibrating screen 4. It is used to guide the broken materials transmitted from the screen surface by vibration. After receiving the broken materials, the receiving plate 34 transmits the broken materials to the vibrating screen 4 in front through vibration. After being screened by the vibrating screen 4, the upper layer of broken materials that have not fallen are transmitted to the discharge plate 35, which facilitates the automatic collection of the upper layer of broken materials.

[0051] In one implementation scheme, as shown in Figures 1-4, the driving mechanism for driving the vibration of the housing 3 includes a vibration motor 5. The vibration motor 5 is located on the housing 3, preferably at the bottom of the housing 3 (e.g., fixed to the bottom plate 31). The vibration motor 5 drives the housing 3 to vibrate, and the housing 3 vibrates relative to the support frame 1 through the composite spring 21, thereby driving the vibrating screen 4 to vibrate and achieve the sorting of crushed materials.
