Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, and in particular to a hydraulic metal baler for metal recycling. Background Technology

[0002] Metal recycling can compress various metal scraps, steel shavings, scrap steel, scrap iron, scrap copper, scrap aluminum, aluminum shavings, dismantled car shells, waste oil drums, and other metal raw materials into qualified furnace materials of various shapes such as cuboids and cylinders, which are convenient for storage, transportation, and recycling.

[0003] According to Chinese Patent Publication No. CN221292435U, a hydraulic metal baler for motor vehicle recycling is designed with a first electric push rod, a push plate, a first telescopic rod, a connecting plate, and a moving plate. In use, the first electric push rod extends and retracts to move the push plate, which in turn pushes the extruded material to adjust its height. Then, the first telescopic rod extends and retracts to move the connecting plate and the moving plate, which in turn push the extruded material. This effectively pushes the extruded material out, reducing the workload of workers and improving the efficiency of the device.

[0004] Existing metal balers typically discharge material from the side of the baler. This requires frequent opening and closing of the side door, increasing the workload of workers and reducing the efficiency of scrap metal output. Therefore, a hydraulic metal baler for metal recycling is proposed to solve these problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6 As shown, the present invention proposes a metal recycling hydraulic metal baler, including a baling shell 1, a hydraulic baling mechanism 2 inside the baling shell 1, a top shielding mechanism 3 above the baling shell 1, four symmetrically distributed support blocks 5 installed on the outer end face of the baling shell 1, support columns 6 installed at the bottom of each of the four support blocks 5, and a material discharge mechanism 4 at the bottom of the baling shell 1.

[0026] In this invention, when baling scrap metal, the top shielding mechanism 3 is first driven to expose the top of the baling shell 1 to the outside. Then, the scrap metal is placed inside the baling shell 1, and the top shielding mechanism 3 shields the top of the baling shell 1. Next, the hydraulic baling mechanism 2 squeezes and bales the scrap metal. After baling is completed, the baled scrap metal is quickly discharged through the discharge mechanism 4, realizing automatic discharge operation.

[0027] The packaging shell 1 is supported by four support blocks 5 and four support columns 6 to ensure the stability of the packaging shell 1.

[0028] In embodiment 1, the material discharge mechanism 4 includes a discharge hole 41, a lifting plate 42, two L-shaped plates 43, two first cylinders 44, a pushing component 45, and a guide plate 46. The discharge hole 41 is opened in the inner bottom wall of the packaging shell 1 and extends to its bottom. The lifting plate 42 is slidably connected to the inside of the discharge hole 41. The top of the lifting plate 42 corresponds to the inner bottom wall of the packaging shell 1. The front and back of the lifting plate 42 correspond to the front and rear side walls of the inner cavity of the packaging shell 1, respectively. The two L-shaped plates 43 are installed at the bottom of the lifting plate 42. The two first cylinders 44 are installed on the front and back of the packaging shell 1, respectively. The piston rods of the two first cylinders 44 are connected to the inner bottom walls of the two L-shaped plates 43, respectively. The pushing component 45 is located between the two support columns 6 on the left side and opposite sides. The guide plate 46 is installed between the two support columns 6 on the right side and opposite sides.

[0029] The lifting plate 42 blocks the discharge hole 41 and supports the bottom of the baling shell 1, thus supporting the bottom of the scrap metal. After the scrap metal is baled, the scrap metal block will be located at the top of the lifting plate 42. At this time, the two first cylinders 44 are activated at the same time. The piston rods of the two first cylinders 44 will drive the two L-shaped plates 43 to move downwards respectively. The two L-shaped plates 43 will drive the lifting plate 42 to move downwards, thereby causing the lifting plate 42 to drive the scrap metal block at its top to move downwards and discharge it from the baling shell 1.

[0030] In embodiment 2, the pushing component 45 includes an L-shaped support frame 451, a second cylinder 452, and a push plate 453. The L-shaped support frame 451 is installed between the two support columns 6 on the left side. The second cylinder 452 is installed on the left side of the L-shaped support frame 451 and extends into it. The push plate 453 is installed on the piston rod of the second cylinder 452. The bottom of the push plate 453 is slidably connected to the inner bottom wall of the L-shaped support frame 451.

[0031] When the lifting plate 42 moves downward to its top, which corresponds to the inner bottom wall of the L-shaped support frame 451, the two first cylinders 44 are closed and the second cylinder 452 is activated. The piston rod of the second cylinder 452 will drive the push plate 453 to move to the right. The push plate 453 will drive the scrap metal block on the top of the lifting plate 42 to move to the right, so that the scrap metal block moves to the top of the guide plate 46. Under the tilting action of the guide plate 46, the scrap metal block slides down along the tilted guide plate 46, realizing automatic discharge.

[0032] After the scrap metal blocks are discharged, the second cylinder 452 is first activated in reverse to return the push plate 453 to its initial position. Then, the two first cylinders 44 are activated in reverse to make the lifting plate 42 slide inside the discharge hole 41, so that the scrap metal can continue to be hydraulically packaged.

[0033] In embodiment 3, the hydraulic packaging mechanism 2 includes two third cylinders 21 and two hydraulic plates 22. The two third cylinders 21 are respectively installed on the left and right sides of the packaging shell 1 and extend into its interior. The two hydraulic plates 22 are respectively installed on the piston rods of the two third cylinders 21. The hydraulic plates 22 are adapted to the packaging shell 1.

[0034] After the scrap metal is placed inside the baling housing 1, the top of the baling housing 1 is covered by the top covering mechanism 3. At this time, the two third cylinders 21 are activated. The piston rods of the two third cylinders 21 will drive the two hydraulic plates 22 to move to opposite sides respectively. With the cooperation of the inner wall of the baling housing 1, the lifting plate 42 and the top covering mechanism 3, the two hydraulic plates 22 can squeeze and bale the scrap metal, so that the scrap metal forms scrap metal blocks. The length of the scrap metal blocks cannot be greater than the length of the lifting plate 42 to avoid affecting the normal discharge of the scrap metal blocks.

[0035] In embodiment four, the top shielding mechanism 3 includes a fixed plate 31, two reinforcing ribs 32, two first mounting seats 33, a fourth cylinder 34, two second mounting seats 35, and a top cover plate 36. The fixed plate 31 is installed on the back of the packaging shell 1. The two reinforcing ribs 32 are both installed at the bottom of the fixed plate 31, and the other ends of the two reinforcing ribs 32 are connected to the back of the packaging shell 1. The two first mounting seats 33 are both installed on the top of the fixed plate 31. The top cover plate 36 is hinged to the top of the packaging shell 1 by a hinge. The two second mounting seats 35 are both installed on the top of the top cover plate 36. The fourth cylinder 34 is hinged between the two first mounting seats 33 on opposite sides by a pin, and the piston rod of the fourth cylinder 34 is hinged between the two second mounting seats 35 on opposite sides by a pin.

[0036] The fixing plate 31 can be used to install the two first mounting seats 33 and the fourth cylinder 34. The two reinforcing ribs 32 can support the fixing plate 31 to ensure the stability of the installation. When the fourth cylinder 34 is started, the piston rod of the fourth cylinder 34 will be driven by the two second mounting seats 35 to rotate the top cover plate 36, thereby opening the top cover plate 36 and exposing the top of the packaging shell 1 to the outside, so that scrap metal can be put into the packaging shell 1. After the scrap metal is placed, the fourth cylinder 34 is started in reverse, which can cause the top cover plate 36 to rotate in the opposite direction, thereby covering the top of the packaging shell 1.

[0037] In Example 5, a controller is installed on the outside of the packaging shell 1. The first cylinder 44, the second cylinder 452, the third cylinder 21 and the fourth cylinder 34 are all electrically connected to the controller. The controller can control the first cylinder 44, the second cylinder 452, the third cylinder 21 and the fourth cylinder 34.

[0038] The two first cylinders 44 are of the same model and are connected to the same air circuit through solenoid valves, thereby ensuring that the controller can control the two first cylinders 44 to maintain relative synchronous movement as much as possible within the allowable error.

[0039] Working principle:

[0040] In operation, this hydraulic metal baler for metal recycling requires first activating the fourth cylinder 34 to flip the top cover 36, opening it and allowing scrap metal to be placed inside the baling housing 1. Then, the fourth cylinder 34 is activated in reverse to close the top cover 36. Next, the two third cylinders 21 are activated, their piston rods driving two hydraulic plates 22 to move to opposite sides. With the cooperation of the inner wall of the baling housing 1, the lifting plate 42, and the top blocking mechanism 3, the two hydraulic plates 22 compress and bale the scrap metal, forming scrap metal blocks. Finally, the first cylinder 44 is activated, causing the lifting plate 42 to move the scrap metal block on its top downwards and discharge it from the packaging shell 1. When the lifting plate 42 moves downwards to the point where its top corresponds to the inner bottom wall of the L-shaped support frame 451, the two first cylinders 44 are closed, and the second cylinder 452 is activated. The piston rod of the second cylinder 452 will drive the push plate 453 to move to the right. The push plate 453 will drive the scrap metal block on the top of the lifting plate 42 to move to the right, so that the scrap metal block moves to the top of the guide plate 46. Under the tilting action of the guide plate 46, the scrap metal block slides down along the tilted guide plate 46, realizing automatic discharge.
