An aluminum scrap collection device for aluminum profile production

Abstract

The present invention discloses an aluminum scrap collection device for aluminum profile production, including a crushing housing. Inside the crushing housing, a pair of main crushing rollers that are misaligned and engaged with each other are movably connected to achieve the purpose of metal crushing. On both sides of the top of the main crushing rollers, guiding mechanisms are provided. By starting the double-shaft motor, the double-shaft motor drives two extension blocks and two main crushing rollers to move outwards, increasing the distance between the two main crushing rollers, changing the direct crushing purpose at the main crushing rollers to primary crushing. Because the distance between the main crushing rollers becomes larger, the engaged part is increased, so that larger or more curved aluminum scraps first pass through the main crushing rollers for primary crushing. Here, the primary crushing does not crush the aluminum but only squeezes the larger aluminum into smaller ones, and then secondary crushing is carried out between the two secondary crushing rollers, that is, the final crushing. The whole process can automatically detect according to the actual situation of the aluminum scraps and automatically start the crushing mode.

Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum scrap collection, and particularly relates to an aluminum scrap collection device for aluminum profile production. Background Art

[0002] Aluminum profile scrap refers to the waste materials generated during the processes of aluminum profile processing, manufacturing, and use. The entire collection device adopts automated control, reducing manual operation and improving work efficiency. Moreover, the device has a simple structure, being easy to operate and maintain. At the same time, the system is equipped with an intelligent control system and a safety protection device, which can monitor the operating status and various parameters of the equipment in real time to ensure the smooth progress of the entire recycling process. Through efficient scrap collection and recycling, resource waste and environmental pollution are reduced. At the same time, recycling aluminum profile scrap can reduce the demand for new aluminum resources and the environmental damage caused by aluminum ore mining. During the process of recycling aluminum profiles, since most aluminum profile scraps are large in volume, they will occupy more storage space, increasing storage costs. Also, during transportation, large scraps not only occupy vehicle space but may also increase the instability and safety hazards of transportation. Moreover, when recycling and reusing aluminum profile scrap, it usually needs to be melted and remanufactured, and large scraps are not easily directly fed into the melting furnace and require additional cutting or crushing. And for traditional crushing and collection equipment, when encountering larger aluminum scraps or aluminum scraps with a larger curvature, manual pressing is often required to achieve faster crushing. Otherwise, it is easy to slip due to volume and curvature reasons, affecting the overall crushing efficiency, and there are safety hazards in manual pressing. Summary of the Invention

[0003] The purpose of the present invention is to provide an aluminum scrap collection device for aluminum profile production to solve the above problems.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An aluminum scrap collection device for aluminum profile production, including a crushing housing, inside which a pair of main crushing rollers that are misaligned and meshed with each other are movably connected to achieve the purpose of metal crushing, and guiding mechanisms are arranged on both sides at the top of the main crushing rollers;

[0005] The guiding mechanism includes a synchronous track, inside which an output shaft of an external motor, a moving shaft, and a compensation shaft for compensation when the moving shaft moves are meshed. The output shaft, the moving shaft, and the compensation shaft are arranged in a triangular shape to guide the added metal materials;

[0006] Both ends of the moving shaft penetrate through the outside of the crushing housing and are slidably connected to the crushing housing. Both ends of the moving shaft extending outside the crushing housing are fixedly connected with pressure detection components. A first threaded rod is threadedly connected inside the pressure detection components, and the thread turns of the two ends of the first threaded rod are opposite, so that when the first threaded rod rotates, the two pressure detection components on one side move relative to each other. One end of each of the two first threaded rods is drivingly connected to a first motor through a first chain, and the first threaded rod is movably installed on the crushing housing through a fixing block;

[0007] Both ends of the compensation shaft penetrate through the crushing housing and are slidably arranged with the crushing housing. Chain compensation components two are arranged at both ends of the compensation shaft and are elastically telescopically connected with the crushing housing through the chain compensation components two to achieve compensation when the moving shaft moves actively.

[0008] Preferably, the central axes of the two main crushing rollers both penetrate through the outside of the crushing housing and are slidably arranged with the crushing housing, and a grading crushing adjustment component capable of closing or opening the two main crushing rollers simultaneously is arranged between the adjacent ends of the central axes of the two main crushing rollers.

[0009] Preferably, the grading crushing adjustment component includes extension blocks fixed at one end of the central axis of the main crushing roller. A second threaded rod is threadedly connected inside each of the two extension blocks, and the thread turns of the two second threaded rods on the adjacent sides are opposite. A double-shaft motor is drivingly connected between the two second threaded rods to drive the two extension blocks and the entire main crushing roller to perform opening and closing movements.

[0010] Preferably, the output shafts of the two guiding mechanisms penetrate through the outside of the crushing housing, and a third reversing shaft is arranged on the outer wall of the crushing housing at the top of one of the output shafts. The third reversing shaft is meshed and connected with the extended end of the output shaft through a gear. The third reversing shaft and the extended end of the other output shaft extending outside the crushing housing are synchronously moved through a second chain to make the two output shafts move relative to each other, so that both of the two synchronous tracks are guided to move inward.

[0011] Preferably, the two output shafts are synchronously moved through a third chain with the central axes of the main crushing rollers adjacent to them respectively, and a chain compensation component one is also slidably connected to the third chain. The telescopic property of the chain compensation component one is used to compensate for the movement process of the main crushing roller.

[0012] Preferably, the chain compensation component one includes a roller group rollingly connected to the third chain. One side of the roller group is fixedly connected with a first moving rod. A first fixing plate fixedly connected with the outer wall of the crushing housing is sleeved outside the first moving rod. A second spring is connected between the first fixing plate and the roller group to achieve elastic compensation.

[0013] Preferably, fixed blocks two are fixedly connected to both ends of the compensation shaft. A second moving rod is observed inside the fixed block two. One end of the second moving rod is fixedly connected to the crushing housing through a second fixing plate. A second spring is arranged between the second fixing plate and the fixed block two, and elastic compensation of the compensation shaft is realized through the second spring.

[0014] Preferably, a pair of secondary crushing rollers, which are in the same vertical line when the two main crushing rollers are in a closed state, are further arranged at the bottom of the main crushing rollers. The two secondary crushing rollers also mesh with each other to achieve the purpose of crushing. The transmission mode between the two secondary crushing rollers is the same as that between the two output shafts. The central shaft of one of the secondary crushing rollers is externally connected to a motor. Relative meshing movement is realized between the central shafts of the two secondary crushing rollers through a third reversing shaft and gears.

[0015] Preferably, the pressure detection assembly includes a nut threadedly connected to the first threaded rod. An intermediate piece is sleeved outside the nut. A spring is connected between the intermediate piece and the nut, and a touch switch is arranged on one side of the intermediate piece close to the nut. The touch switch is electrically connected to the dual-axis motor.

[0016] The technical effects and advantages of the present invention: By using the timer to start the first motor, driving the first threaded rod to rotate, thereby driving the two first threaded rods to move relatively. During the movement, the aluminum scrap will be squeezed. If it is continuously crushed due to the movement of the synchronous track during the squeezing process, it will be normally reset and timed to start again. If the aluminum scrap cannot be quickly pressed between the main crushing rollers for crushing even with the relative movement of the synchronous track after squeezing, because the first motor continues to start and the first threaded rod continues to rotate, when the moving shaft cannot squeeze the scrap, the nut driven by the first threaded rod will continuously squeeze the spring until it presses against the touch switch. At this time, the dual-axis motor will be started, and the two extension blocks and the two main crushing rollers will be driven by the dual-axis motor to move outward, increasing the distance between the two main crushing rollers, changing the direct crushing purpose at the main crushing rollers to primary crushing. Because the distance between the main crushing rollers becomes larger and the meshing part increases, larger or more curved aluminum scraps will first pass through the main crushing rollers for primary crushing. Here, the primary crushing does not crush the aluminum but only squeezes the larger aluminum into smaller ones, and then secondary crushing is carried out between the two secondary crushing rollers, that is, the final crushing. The whole process can automatically detect and start the crushing mode according to the actual situation of the aluminum scrap. The whole process does not require too much manual participation, reducing potential safety hazards and having a high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides an aluminum profile production aluminum scrap collection device as shown in the figure, including a crushing housing 3. Inside the crushing housing 3, a pair of main crushing rollers 5 that are misaligned and meshed with each other are movably connected to achieve the purpose of metal crushing. On both sides of the top of the main crushing roller 5, a guiding mechanism is provided;

[0027] The guiding mechanism includes a synchronous track 4. Inside the synchronous track 4, the output shaft 20 of an external motor, the moving shaft 13, and the compensation shaft 902 that compensates when the moving shaft 13 moves are meshed. The output shaft 20, the moving shaft 13, and the compensation shaft 902 are arranged in a triangle to guide the added metal material;

[0028] Both ends of the moving shaft 13 penetrate through the outside of the crushing housing 3 and are slidably connected to the crushing housing 3. Both ends of the moving shaft 13 extending to the outside of the crushing housing 3 are fixedly connected with pressure detection components 11. A first threaded rod 12 is threadedly connected inside the pressure detection components 11, and the thread directions at both ends of the first threaded rod 12 are opposite, so that when the first threaded rod 12 rotates, the two pressure detection components 11 on one side move relative to each other. One end of the two first threaded rods 12 is drivingly connected to a first motor 2 through a first chain, and the first threaded rod 12 is movably installed on the crushing housing 3 through a fixing block 10;

[0029] Both ends of the compensation shaft 902 penetrate through the crushing housing 3 and are slidably arranged with the crushing housing 3. Chain compensation components II 9 are arranged at both ends of the compensation shaft 902 and are elastically telescopically connected to the crushing housing 3 through the chain compensation components II 9 to achieve compensation when the moving shaft 13 moves actively.

[0030] Specifically, the central axes of the two main crushing rollers 5 both penetrate through the outside of the crushing housing 3 and are slidably arranged with the crushing housing 3, and a grading crushing adjustment component 6 that can close or open the two main crushing rollers 5 simultaneously is arranged between the adjacent ends of the central axes of the two main crushing rollers 5.

[0031] Specifically, the grading crushing adjustment component 6 includes extension blocks 603 fixed at one end of the central axis of the main crushing roller 5. A second threaded rod 602 is threadedly connected inside the two extension blocks 603, and the thread directions of the two second threaded rods 602 on the adjacent sides are opposite. A double-shaft motor 601 is drivingly connected between the two second threaded rods 602 to drive the two extension blocks 603 and the entire main crushing roller 5 to perform opening and closing movements.

[0032] Specifically, the output shafts 20 of the two guiding mechanisms penetrate through the outside of the crushing housing 3, and on the outer wall of the crushing housing 3 at the top of one of the output shafts 20, a third reversing shaft 15 is arranged. The third reversing shaft 15 is meshed with the extended end of the output shaft 20 through a gear. The third reversing shaft 15 and the extended end of the other output shaft 20 extending outside the crushing housing 3 are synchronously moved through a second chain 16 to make the two output shafts 20 move relative to each other, so that both of the two synchronous tracks 4 are guided to move inward.

[0033] Specifically, the two output shafts 20 are synchronously moved with the central axes of the main crushing rollers 5 adjacent to themselves through a third chain 802, and a chain compensation component I 8 is also slidably connected to the third chain 802. The telescopic property of the chain compensation component I 8 is used to compensate for the movement process of the main crushing roller 5.

[0034] Specifically, the first chain compensation assembly 8 includes a roller group 801 that is in rolling connection with the third chain 802. One side of the roller group 801 is fixedly connected to a first moving rod 805. The outside of the first moving rod 805 is sleeved with a first fixing plate 804 that is fixedly connected to the outer wall of the crushing housing 3. A second spring 803 is connected between the first fixing plate 804 and the roller group 801 to achieve elastic compensation.

[0035] Specifically, both ends of the compensation shaft 902 are fixedly connected to second fixing blocks 904. A second moving rod 905 is observed inside the second fixing blocks 904. One end of the second moving rod 905 is fixedly connected to the crushing housing 3 through a second fixing plate 901. A second spring 903 is arranged between the second fixing plate 901 and the second fixing blocks 904, and elastic compensation of the compensation shaft 902 is achieved through the second spring 903.

[0036] Specifically, a pair of secondary crushing rollers 14 are further arranged at the bottom of the main crushing roller 5. When the two main crushing rollers 5 are in a closed state, the secondary crushing rollers 14 are on the same vertical line. The two secondary crushing rollers 14 also mesh with each other to achieve the crushing purpose. The transmission method between the two secondary crushing rollers 14 is the same as that between the two output shafts 20. The central shaft of one of the secondary crushing rollers 14 is externally connected to a motor. Relative meshing movement is achieved between the central shafts of the two secondary crushing rollers 14 through a third reversing shaft and gears.

[0037] Specifically, the pressure detection assembly 11 includes a nut 1102 that is threadedly connected to the first threaded rod 12. The outside of the nut 1102 is sleeved with an intermediate member 1103. A spring 1101 is connected between the intermediate member 1103 and the nut 1102. A touch switch is arranged on one side of the intermediate member 1103 close to the nut 1102. The touch switch is electrically connected to the dual-axis motor 601.

[0038] Working principle: Example 1: By putting aluminum scrap of different shapes between two synchronous tracks 4 inside the crushing housing 3, the entire synchronous track 4 is driven to move by a motor externally connected to the output shaft 20, so as to import the aluminum scrap between two main crushing rollers 5 for crushing. During the crushing process, it is often encountered that some arc-shaped or larger aluminum scraps cannot be crushed immediately and need to be manually pressed into the space between the two main crushing rollers 5 for crushing, otherwise slipping is likely to occur due to the size and curvature. At this time, the motor 1 2 can be started regularly to drive the threaded rod 1 12 to rotate, thereby driving the two threaded rods 1 12 to move relatively. During the movement, the aluminum scrap will be squeezed. If the aluminum scrap is continuously crushed due to the movement of the synchronous track 4 during the squeezing process, it will be reset regularly and then started again. If the aluminum scrap cannot be quickly pressed between the main crushing rollers 5 for crushing even with the relative movement of the synchronous track 4 after squeezing, because the motor 1 2 keeps starting and the threaded rod 1 12 keeps rotating, when the moving shaft 13 cannot squeeze the scrap, the nut 1102 driven by the threaded rod 1 12 will continuously squeeze the spring 1101 until it presses against the touch switch. At this time, the dual-shaft motor 601 will be started. The dual-shaft motor 601 drives two extension blocks 603 and two main crushing rollers 5 to move outwards, increasing the distance between the two main crushing rollers 5, changing the direct crushing purpose at the main crushing rollers 5 to primary crushing. Because the distance between the main crushing rollers 5 becomes larger, the biting part is increased, so that larger or more curved aluminum scraps first pass through the main crushing rollers 5 for primary crushing. Here, the primary crushing does not crush the aluminum but only squeezes the larger aluminum into smaller pieces, and then secondary crushing is carried out between two secondary crushing rollers 14, that is, the final crushing. The whole process can automatically detect and start the crushing mode according to the actual situation of the aluminum scrap. The motor externally connected to the secondary crushing roller 14 here is electrically connected to the touch switch in the same way as the dual-shaft motor 601. That is, during normal crushing, the secondary crushing roller 14 is not started. And the meshing gears of the secondary crushing roller 14 are arranged out of alignment with the meshing gears of the main crushing roller 5 at its top, which can act as a structure for removing metal residues in the meshing gap of the main crushing roller 5 when the secondary crushing roller 14 does not rotate. And a cleaning plate 17 is fixedly arranged on the inner wall of the crushing housing 3 at the bottom of the secondary crushing roller 14, which can remove metal residues from the secondary crushing roller 14 participating in the crushing. The whole process does not require too much manual participation, reduces potential safety hazards, and has a high degree of automation.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
