Description

Technical Field

[0001] This utility model relates to the field of metal baling machine technology, and in particular to a metal baling machine with a limiting structure. Background Technology

[0002] A metal baler is a pressing machine that compresses and organizes non-metallic and scattered metal structures to form a baled whole. It is a pressing and baling device for scrap metal. This device can package and reuse scrap metal resources, realizing the concept of energy conservation and environmental protection.

[0003] An existing metal baling machine with a limiting function, as disclosed in CN 221851271 U, limits the downward movement of the pressure plate by rotating the limiting buckle on the support rod, thereby ensuring that the loose metal will not be deformed due to distance during the baling process. However, the limiting buckle on the support rod is installed at the upper end, which makes it inconvenient to adjust due to the height of the equipment, causing problems for users. Utility Model Content

[0004] The purpose of this invention is to provide a metal baling machine with a limiting structure in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A metal baling machine with a limiting structure includes a baling mechanism for applying pressure and baling. The baling mechanism includes a frame, a baling cavity with a front opening at the lower end of the frame, a movable door movably connected to the front side of the baling cavity, a top plate fixed to the upper end of the frame, a hydraulic rod installed at the upper end of the top plate, a pressure plate connected to the lower end of the hydraulic rod, and a limiting mechanism for adjusting and limiting the baling pressure height. The limiting mechanism includes a guide post fixed to the upper end of the pressure plate, an inverted L-shaped slide rod fixed to the upper end of the guide post, and a limiting component for limiting the downward pressure position of the L-shaped slide rod on one side of the frame. The limiting component includes an upper support plate and a lower support frame, a lead screw vertically installed on the upper support plate and the lower support frame, an adjusting plate installed on the lead screw, a reversing switch installed at the upper end of the adjusting plate corresponding to the lower side of the L-shaped slide rod, and a power component connected to the lower end of the lead screw.

[0007] Further configuration: The power assembly includes a secondary bevel gear fixed to the lower end of the lead screw, a rotating shaft on the lower support frame, a driving bevel gear meshing with the secondary bevel gear mounted on the rotating shaft, and a handwheel mounted at the front end of the rotating shaft.

[0008] Further configuration: The rotating shaft is rotatably connected to the lower support frame, and the lead screw is rotatably connected to the upper support plate and the lower support frame.

[0009] Further details: The limiting mechanism is positioned opposite each other on both sides, and a transmission component is installed at the rear end of the rotating shaft.

[0010] Further details: The guide post and L-shaped slide rod are slidably connected to the top plate, and a through groove corresponding to the L-shaped slide rod is opened on the upper support plate.

[0011] Further settings: Adjust the connection between the adjustment plate and the lead screw thread.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting a limit mechanism, when adjusting the downward stroke of the pressure plate, the power component drives the lead screw to rotate, adjusting the position of the adjustment plate on the lead screw. Then, as the hydraulic rod extends and pushes the pressure plate and guide column downward, the L-shaped slide rod moves downward until it contacts the reversing switch. At this point, the hydraulic rod retracts, and the pressure plate is lifted upward, improving the convenience of adjusting the downward stroke of the pressure plate. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a metal baling machine with a limiting structure includes a baling mechanism for applying pressure to the baling, and a limiting mechanism for adjusting and limiting the baling pressure height.

[0025] In this embodiment: the packaging mechanism includes a frame 11, a packaging cavity 12 with a front opening at the lower end of the frame 11, a movable door 13 connected to the front side of the packaging cavity 12, a top plate 14 fixed at the upper end of the frame 11, a hydraulic rod 15 installed at the upper end of the top plate 14, a hydraulic control system connected to the hydraulic rod 15 to control the extension and retraction of the hydraulic rod 15, and a pressure plate 16 connected to the lower end of the hydraulic rod 15. When metal is placed in the packaging cavity 12, the extension of the hydraulic rod 15 pushes the pressure plate 16 downward to apply pressure to the metal below.

[0026] In this embodiment: the limiting mechanism includes a guide post 21 fixed to the upper end of the pressure plate 16, and an inverted L-shaped slide rod 22 fixed to the upper end of the guide post 21. A limiting component is provided on one side of the frame 11 to limit the downward position of the L-shaped slide rod 22. The limiting component includes an upper support plate 23 and a lower support frame 24. A lead screw 25 is vertically provided on the upper support plate 23 and the lower support frame 24. An adjustment plate 26 is installed on the lead screw 25. A reversing switch 27 is provided on the lower side of the upper end of the adjustment plate 26 corresponding to the lower side of the L-shaped slide rod 22. The reversing switch 27 is connected to the hydraulic control system. When the reversing switch 27 is squeezed, the hydraulic oil circuit of the hydraulic rod 15 is reversed. This is a hydraulic oil circuit control system technology, which is a conventional technology in hydraulic systems and will not be described in detail here. A power component is connected to the lower end of the lead screw 25.

[0027] The power assembly includes a secondary bevel gear 28 fixed to the lower end of the lead screw 25, a rotating shaft 29 on the lower support frame 24, a driving bevel gear 210 that meshes with the secondary bevel gear 28 on the rotating shaft 29, and a handwheel installed at the front end of the rotating shaft 29. The guide post 21 and the L-shaped slide rod 22 are slidably connected to the top plate 14. The upper support plate 23 has a through groove corresponding to the L-shaped slide rod 22. The adjusting plate 26 is threadedly connected to the lead screw 25. The rotating shaft 29 is rotatably connected to the lower support frame 24. The lead screw 25 is rotatably connected to the upper support plate 23 and the lower support frame 24. By rotating the rotating shaft 29, the driving bevel gear 210 on the rotating shaft 29 meshes with the auxiliary bevel gear 28 and rotates. The auxiliary bevel gear 28 drives the lead screw 25 to rotate, adjusting the position of the adjusting plate 26 on the lead screw 25. Then, the hydraulic rod 15 extends to push the pressure plate 16 and the guide post 21 downward. At the same time, the L-shaped slide rod 22 moves downward with the guide post 21 until the L-shaped slide rod 22 passes through the upper support plate 23 and contacts the reversing switch 27 on the adjusting plate 26. The hydraulic rod 15 retracts, lifting the pressure plate 16 upward and limiting the downward stroke of the pressure plate 16.

[0028] The limiting mechanism is arranged on both sides opposite each other. A transmission component 211 is installed at the rear end of the rotating shaft 29. The transmission component 211 is a synchronous pulley, and a synchronous belt is sleeved on the transmission component 211.

[0029] The working principle and usage process of this utility model are as follows: The metal is placed in the packaging chamber 12. The required height for applying pressure to the metal is determined by rotating the rotating shaft 29, which causes the active bevel gear 210 on the rotating shaft 29 to mesh with the auxiliary bevel gear 28. The auxiliary bevel gear 28 drives the lead screw 25 to rotate, adjusting the position of the adjusting plate 26 on the lead screw 25. Then, the hydraulic rod 15 extends to push the pressure plate 16 and the guide post 21 downward. At the same time, the L-shaped slide rod 22 moves downward with the guide post 21 until the L-shaped slide rod 22 passes through the upper support plate 23 and contacts the reversing switch 27 on the adjusting plate 26. The hydraulic rod 15 then retracts, lifting the pressure plate 16 upward.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
