DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application.

[0034] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including a..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0035] The present application embodiment provides a steel strapping recycling system, combined with Figure 2 The three-dimensional structural diagram of the steel strapping recovery system is shown, and Figure 3 , Figure 4 As shown in the front view and top view, the steel strap recycling system includes a strapping device 21, a strapping sorting and shearing device 22 and a steel strap welding device 23, wherein:

[0036] The debundling device 21 can be used to debundle steel coils to obtain steel straps. In the embodiment of the present application, high-value parts and low-value parts of the steel straps can be classified and sheared for recycling.

[0037] In addition, combined Figure 2 As shown, the debundling device 21 may include a debundling head 211 and an industrial robot 212. The industrial robot 212 can be used to control the debundling head 211 to debundle the steel coils to obtain steel straps. For example, in actual applications, an automatic control program can be usually set in the industrial robot 212, or the industrial robot 212 can be manually operated to control the debundling head 211 to debundle the steel coils to obtain steel straps.

[0038] Of course, after obtaining the steel strap, the industrial robot 212 can also be used to control the debaling head 211 to transfer the steel strap to the strap sorting and shearing device 22, thereby facilitating the sorting and shearing device 22 to perform its function.

[0039] Among them, the strap classification and shearing device 22 can be used to classify and shear the high-value parts and low-value parts in the steel strap. For example, the strap classification and shearing device 22 can shear the junction (or near the junction) between the high-value part and the low-value part, thereby achieving classification and shearing of the two.

[0040] It should be emphasized that in the embodiment of the present application, after the steel coils are unbundled to obtain the steel straps, the steel straps are not directly recycled, but the high-value parts and low-value parts of the steel straps are further identified and then classified for recycling. Therefore, in the embodiment of the present application, how to identify the high-value parts and low-value parts of the steel straps is crucial for the classified cutting and classified recycling of the two. Among them, how to identify the high-value parts and low-value parts of the steel straps will be explained in detail later.

[0041] In addition, the high-value portion specifically refers to a portion of the steel strapping having a relatively high value, and the low-value portion specifically refers to a portion of the steel strapping excluding the high-value portion.

[0042] Regarding the steel strap welding device 23 in the steel strap recycling system in the embodiment of the present application, the steel strap welding device 23 can be used to weld the multiple high-value parts obtained by the strap classification and shearing device 22 into new steel straps. For example, after the strap classification and shearing device 22 classifies and shears the high-value parts and low-value parts in the steel strap, the high-value parts will be transmitted to the steel strap welding device 23, so that the steel strap welding device 23 can re-weld these high-value parts to obtain the new steel strap. Obviously, the new steel strap is composed of the high-value parts in the steel strap, so it has a high recycling value.

[0043] The steel strap recycling system provided in the embodiment of the present application is adopted, and the steel strap recycling system includes: a debundling device 21, a strap sorting and shearing device 22 and a steel strap welding device 23. The debundling device 21 can be used to debundle the steel coils to obtain steel straps. The strap sorting and shearing device 22 can be used to sort and shear the high-value parts and low-value parts in the steel straps. The steel strap welding device 23 can be used to weld the multiple high-value parts obtained by sorting and shearing the strap sorting and shearing device 22 into new steel straps. Obviously, the new steel straps are all composed of the high-value parts in the steel straps, so they have a high recycling and reuse value.

[0044] After the steel strap welding device 23 welds multiple high-value parts into new steel straps, in order to facilitate the storage of the new steel straps, it can be further combined with Figure 2As shown, the steel strap recycling system may further include a curling and recycling device 24, wherein the curling and recycling device 24 can be used to curl and recycle the new steel strap. After the steel strap welding device 23 welds multiple high-value parts into new steel straps, the new steel straps can be transferred to the curling and recycling device 24, so that the new steel straps in strip form can be curled and recycled by the curling and recycling device 24, thereby facilitating their management.

[0045] In practical applications, a loop 231 can usually be provided in the steel strap welding device 23, and the loop 231 can be used to store the new steel strap. For example, after the steel strap welding device 23 welds multiple high-value parts into new steel straps, the new steel strap can be stored in the loop 231 first, and then the new steel strap can be transmitted to the curling and recovery device 24 through the loop 231, so that the curling and recovery device 24 can curl and recover the new steel strap.

[0046] Here, the strap sorting and shearing device 22 in the steel strap recycling system in the embodiment of the present application can be further explained. In actual applications, there can be multiple implementation principles of the strap sorting and shearing device 22. For example, one method can use the technical route of image recognition to identify the high-value parts and low-value parts in the steel strap, and classify and shear the two, thereby providing a basis for classified recycling. Another method can use the technical route of sensors to identify the high-value parts and low-value parts in the steel strap, and classify and shear the two. In the embodiment of the present application, the technical route of sensors is adopted, and the technical solution of this technical route will be described in detail here.

[0047] In the present application, the strap sorting and shearing device 22 includes a strap feeding component, a sensing sensor component and a sorting and shearing module, wherein: the strap feeding component can be used to transmit steel straps, the sensing sensor component can be used to sense the thickness of the detected part of the steel strap, and the sorting and shearing module can be used to sort and shear the steel straps according to the sensing results of the sensing sensor component.

[0048] For example, the steel strap is conveyed to the sensing sensor assembly by the strap feeding component, so that the sensing sensor assembly can sense the thickness of the detected portion of the steel strap, and then the shearing module can classify and shear the steel strap according to the sensing result of the sensing sensor assembly, that is, the thickness of the detected portion.

[0049] At this time, if the thickness of the detected part is greater than the reference thickness, it means that the detected part may have nodules due to the welding process, so the detected part can be determined as a low-value part; conversely, if the thickness of the detected part is less than or equal to the reference thickness, it means that the detected part has no nodules, so the detected part can be determined as a high-value part. In the embodiment of the present application, the low-value part is specifically a part of the steel strapping where the actual thickness is greater than the reference thickness, and the high-value part is specifically a part of the steel strapping where the actual thickness is less than or equal to the reference thickness. That is to say, in the embodiment of the present application, it is necessary to first identify the thickness of the detected part through the inductive sensor assembly. Since the thickness of the detected part indicates whether it has nodules, it can directly reflect its value, which provides a prerequisite for subsequent classification and shearing.

[0050] Among them, the size of the reference thickness can usually be set according to actual conditions, for example, the size of the reference thickness can be determined according to the type and model of the steel strap; in addition, the detected part can be any part of the steel strap, for example, when the steel strap is driven by the belt feeding component and sent to the sensing sensor component, the sensing sensor component can identify the part close to itself, so the part of the steel strap close to the sensing sensor component can be used as the detected part.

[0051] It should be noted that the belt feeding component may include an active belt feeding wheel 221 and a driven belt feeding wheel 222. The active belt feeding wheel 221 can be directly controlled by a motor to actively drive the steel strap by rotating, while the driven belt feeding wheel 222 rotates and drives the steel strap by passive means. Of course, when necessary, the belt feeding component may also include a transmission belt, which may be arranged on the active belt feeding wheel 221 and the driven belt feeding wheel 222, and then the active belt feeding wheel 221 and the driven belt feeding wheel 222 drive the transmission belt, thereby transmitting the steel strap.

[0052] In practical applications, the inductive sensor assembly in the strap sorting and shearing device 22 may specifically include an inductive blocking plate 223 and a sensor 224, wherein the sensor 224 can detect the thickness of the steel strap. In practical applications, the sensor 224 may specifically be a pressure sensor, which can sense the pressure transmitted by the inductive blocking plate 223. The distance between the connecting line between the active tape feed wheel 221 and the driven tape feed wheel 222 and the inductive blocking plate 223 may be approximately the reference thickness or slightly less than the reference thickness, so that the active tape feed wheel 221 and the driven tape feed wheel 222 can squeeze the inductive blocking plate 223 when conveying the steel strap to flow through the inductive blocking plate 223, thereby transmitting the pressure to the sensor, so that the sensor can sense the pressure, and then determine the thickness of the detected part according to the magnitude of the pressure.

[0053] It should be noted that, in addition to being the pressure sensor, the sensor 224 can also be an inductive blocking plate proximity switch, which can be used to sense the distance between the inductive blocking plate 223 and the line connecting the active tape feed wheel 221 and the driven tape feed wheel 222, so as to determine the thickness of the detected part according to the distance. For example, when the steel strap is being transmitted through the inductive blocking plate 223, if the thickness of the detected part is greater than the reference thickness, the inductive blocking plate 223 will be squeezed, thereby causing the inductive blocking plate proximity switch to detect a change in distance (according to specific actual needs, the detection can be achieved by increasing or decreasing the distance), so as to determine whether the thickness of the detected part is greater than the reference thickness.

[0054] In practical applications, the sensor 224 can be arranged on a sensor mounting plate 225, and the sensor mounting plate 225 can be provided with a tower spring 226, so that the distance between the induction blocking plate 223 and the line connecting the active tape feed wheel 221 and the driven tape feed wheel 222 can be adjusted by adjusting the screw to compress the tower spring 226, so that a portion with a thickness less than or equal to the reference thickness can pass through, while a portion with a thickness greater than the reference thickness is blocked.

[0055] In addition, a reducer 227 may be provided at the entrance of the driven belt-feeding wheel 222, so that the steel strap at the entrance of the driven belt-feeding wheel 222 is decelerated by the reducer 227. Of course, the device may also include a controller 2211, which may be used to control the rotation speed of the active belt-feeding wheel 221 and the classification and shearing of the steel strap by the classification and shearing module. In practical applications, the controller 2211 may usually be provided at the bottom of the reducer 227.

[0056] It should be emphasized that the classification and shearing module can generally include a shearing cylinder 228, a shearing head 229 and a transmission component 2210, wherein: the shearing cylinder 228 is used to provide shearing force, the transmission component 229 is used to transmit the shearing force provided by the cylinder to the shearing head, and the shearing head 2210 is used to use the shearing force to shear the steel strapping.

[0057] Further in combination with the schematic diagram provided by the present application, the shear cylinder 228 may further include a lifting cylinder 2281 and a belt pressing cylinder 2282, wherein the lifting cylinder 2281 can convert the pressure of the internal gas into mechanical force, thereby pushing or pulling the object, thereby achieving the shear force in the present application. The belt pressing cylinder 2282 can adjust the load, thereby adjusting the shear force of the lifting cylinder 2281 to achieve more precise control.

[0058] In the present application, the transmission component 2210 may include various transmission arms such as a belt pressing arm, through which the shear force generated by the shear cylinder 228 can be transmitted, so that the shear head 229 can use the shear force to shear the steel strap.

[0059] It should be noted that the shearing blade 229 is composed of two cutting blades, one of which is fixed and is called a fixed cutting blade 2291, and the other is movable in the shearing direction and is called a movable cutting blade 2292. In this way, the movable cutting blade 2292 can move toward the fixed cutting blade 2291 in the shearing direction under the action of the shearing force, thereby shearing the steel strap.

[0060] In this way, through the strap sorting and shearing device 22 provided in the embodiment of the present application, when the steel strap is transported by the active strap wheel 221 and the driven strap wheel 222 through the sensing blocking plate 223, the sensor 224 (for example, the sensor 224 is specifically a sensing blocking plate proximity switch at this time) can sense the distance between the sensor 224 and the sensing blocking plate 223. When the distance changes, it indicates that the detected part of the steel strap has changed. Then the controller 2211 can generate a corresponding control signal to control the lifting cylinder 2281 to provide a corresponding shearing force. After the shearing force is adjusted by the strap pressing cylinder 2282, it is transmitted to the movable cutter 2292 in the shearing cutter head 229 by the transmission component 2210, thereby making the movable cutter 2292 move toward the fixed cutter 2291 in the shearing direction to shear the steel strap, thereby achieving the invention purpose of the present application.

[0061] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
