Description

Technical Field

[0001] This utility model relates to the field of metal scrap baling, and in particular to a high-precision fully automatic metal scrap baling machine. Background Technology

[0002] The following are common problems with metal scrap balers currently on the market:

[0003] 1. Low baling efficiency: The baling cycle of metal scrap balers on the market is generally 90s-150s, resulting in low production capacity and high electricity costs.

[0004] 2. High labor costs and inconsistent baling weights: Conventional metal scrap balers require manual control of the feeding equipment, and the weight of each feeding is estimated manually by visual inspection. This results in a large number of manual laborers being needed to operate the metal scrap baler and the baling effect not only being unreliable, but also affecting the final sales of the product and the furnace charging efficiency of steelmaking enterprises.

[0005] 3. Rapid equipment wear: Currently, the contact between the material box and the pusher of the metal scrap baler used in the market is a planar contact, without an effective matching structure to avoid material jamming. Therefore, existing metal scrap balers are prone to material jamming. After each time the equipment clears the jammed material, it needs to pressurize or cut to deal with the jamming. This inevitably causes wear on the material box beyond normal use, making rapid wear a common problem for equipment in the market. This, in turn, causes defects such as burrs or sharp edges on the edges of the baled blocks.

[0006] Therefore, a new type of packing machine structure needs to be designed to solve the above problems. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a high-precision fully automatic metal scrap baler with a conveyor belt feeding device that feeds materials into a raw material storage hopper. A weighing sensor on the hopper weighs the required metal scrap, and then a discharger opens the hopper, causing the metal scrap to fall into the second pressing and forming chamber. This replaces manual feeding, saving labor costs and improving feeding efficiency. A side cylinder drives a side pusher to squeeze the metal scrap, followed by a pressing head cylinder driving the pressing head to squeeze the metal scrap. Finally, the main cylinder drives the main pusher to squeeze the metal scrap. Furthermore, the main pusher and the main pressing forming chamber, the side pusher and the second pressing forming chamber, and the pressing head and the third pressing forming chamber all utilize a forming structure with multiple forming grooves and protrusions to squeeze the metal scrap. This prevents gaps from forming on the mating surfaces of the side pusher and the second pressing forming chamber, the pressing head and the third pressing forming chamber, and the main pusher and the main pressing forming chamber after prolonged friction, thus avoiding burrs or sharp edges on the edges of the baled blocks and improving the forming quality of the baled blocks.

The raw material storage hopper is positioned above the second pressing forming chamber. The conveyor belt feeding device is adjacent to the raw material storage hopper and feeds material into it. The raw material storage hopper is equipped with a weighing sensor for weighing the metal scrap, and a discharge device is located at the bottom of the hopper. A side pusher is slidably connected within the second pressing forming chamber. The side cylinder is positioned within the second pressing forming chamber and connected to the side pusher. The pressing box... A third pressing and forming cavity and a pressure head cylinder are provided at the top of the junction of the main pressing and forming cavity and the second pressing and forming cavity.

The main pushing head is slidably connected in the main pressing and forming cavity, and the output end of the main cylinder is connected to the main pushing head. The metal waste is squeezed by a forming structure with multiple forming grooves and multiple forming protrusions between the main pushing head and the main pressing and forming cavity, between the side pushing head and the second pressing and forming cavity, between the pressure head and the third pressing and forming cavity, between the main pushing head and the side pushing head, and between the main pushing head and the pressure head.

[0009] Preferably, the conveyor belt feeding device includes a conveyor frame and a conveyor, the conveyor frame is inclined upward toward the raw material storage hopper, and the conveyor is disposed on the conveyor frame and feeds material into the raw material storage hopper.

[0010] Preferably, the raw material storage hopper is mounted on the pressing box above the second pressing and forming cavity via a bracket, and the weighing sensor is mounted on the bracket to weigh the metal waste in the raw material storage hopper.

[0011] Preferably, the two unloaders are respectively arranged on the front and rear sides of the raw material storage hopper. The unloader includes two hopper cylinders that are hinged to each other in opposite directions. Hopper gate plates are hinged to the left and right sides of the bottom surface of the raw material storage hopper. The output end of one hopper cylinder on the front and rear sides of the raw material storage hopper is hinged to one of the hopper gate plates, and the output end of the other hopper cylinder on the front and rear sides of the raw material storage hopper is hinged to the other hopper gate plate.

[0012] Preferably, a baffle plate is provided on the top surface of the pressing box below the raw material storage hopper, and a side pusher cover plate is provided on the side of the side pusher facing the side cylinder.

[0013] Preferably, it further includes a main cylinder auxiliary support, which is disposed between the main cylinder and the pressing box, and the main push head is housed in the main cylinder auxiliary support.

[0014] Preferably, the main cylinder auxiliary support is a hollow base, and the length of the main cylinder auxiliary support is less than the length of the main push head.

[0015] Preferably, the pressing box body is provided with a through groove at the discharge port position of the main pushing forming cavity away from the main pushing head, and a material blocking gate is slidably connected in the through groove.

[0016] Preferably, it also includes a material stop cylinder, the material stop having an opening larger than the discharge port of the main forming cavity, the material stop cylinder being disposed adjacent to the material stop on the side wall of the pressing box, and the output end of the material stop cylinder being connected to the material stop.

[0017] Preferably, it also includes a discharge conveyor frame, which is located at the position of the material gate and is inclined outward and upward.

[0018] The beneficial effects of this utility model are as follows: This high-precision fully automatic metal scrap baler uses a conveyor belt feeding device, a raw material storage hopper, a pressing box, a main cylinder, and a side cylinder in cooperation. The conveyor belt feeding device feeds material into the raw material storage hopper, where a weighing sensor measures the required metal scrap.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0030] like Figures 1 to 9As shown, a high-precision fully automatic metal scrap baler includes a conveyor belt feeding device 1, a raw material storage hopper 2, a pressing box 3, a main cylinder 4, and a side cylinder 5. The pressing box 3 is equipped with a main pushing forming chamber 6 and a second pressing forming chamber 7, which are connected to each other. The raw material storage hopper 2 is positioned above the second pressing forming chamber 7. The conveyor belt feeding device 1 is adjacent to the raw material storage hopper 2 and feeds material into it. The raw material storage hopper 2 is equipped with a weighing sensor 8 for weighing the metal scrap, and a discharger is located at the bottom of the raw material storage hopper 2. A side pusher 9 is slidably connected inside the second pressing forming chamber 7. The side cylinder 5 is located inside the second pressing forming chamber 7 and is connected to the side pusher 9. The top of the pressing box 3 is... A third pressing and forming cavity 10 and a pressing head cylinder 11 are provided at the junction of the main pressing forming cavity 6 and the second pressing forming cavity 7. The output end of the pressing head cylinder 11 is provided with a pressing head 12 that moves along the third pressing and forming cavity 10. The main cylinder 4 and the pressing box 3 are arranged in sequence. A main push head 13 is slidably connected in the main pressing forming cavity 6, and the output end of the main cylinder 4 is connected to the main push head 13. The metal waste is squeezed by a forming structure with multiple forming grooves and multiple forming protrusions between the main push head 13 and the main pressing forming cavity 6, between the side push head 9 and the second pressing and forming cavity 7, between the pressing head 12 and the third pressing and forming cavity 10, between the main push head 13 and the side push head 9, and between the main push head 13 and the pressing head 12.

[0031] The high-precision fully automatic metal scrap baler described in this utility model works by the coordinated operation of a conveyor belt feeding device 1, a raw material storage hopper 2, a pressing box 3, a main cylinder 4, and a side cylinder 5. Figures 1 to 9As shown, the conveyor belt feeding device 1 feeds material into the raw material storage hopper 2. The weighing sensor 8 on the raw material storage hopper 2 weighs the required metal scrap. Then, the unloader opens the raw material storage hopper 2 and lets the metal scrap fall into the second pressing and forming chamber 7. The side cylinder 5 drives the side push head 9 to squeeze the metal scrap. Then, the pressing head cylinder 11 drives the pressing head 12 to squeeze the metal scrap. Finally, the main cylinder 4 drives the main push head 13 to squeeze the metal scrap. Multiple [connections] are made between the main push head 13 and the main pressing and forming chamber 6, between the side push head 9 and the second pressing and forming chamber 7, and between the pressing head 12 and the third pressing and forming chamber 10. The forming structure, consisting of forming grooves and multiple forming protrusions, extrudes metal scrap. Multiple forming grooves and protrusions guide the material between the periphery of the side pusher 9 and the cavity wall of the second pressing forming cavity 7; multiple forming grooves and protrusions guide the material between the periphery of the pressure head 12 and the cavity wall of the third pressing forming cavity 10; multiple forming grooves and protrusions guide the material between the periphery of the main pusher 13 and the cavity wall of the main push forming cavity 6; multiple forming grooves and protrusions guide the material between the rear side of the main pusher 13 and the front side of the side pusher 9; and the top surface of the main pusher 13 and the pressure head... Multiple forming grooves and forming protrusions between the bottom surfaces of 12 provide guidance and cooperation. The main push head 13, main forming cavity 6, side push head 9, second pressing forming cavity 7, pressure head 12, and third pressing forming cavity 10 are connected by bolts to install wear-resistant shaped steel plates as mating surfaces. The cross-sections of the forming grooves and forming protrusions can adopt V-shaped, U-shaped, S-shaped, and trapezoidal shapes, etc. A V-shaped structure is used as an example to illustrate the forming grooves and forming protrusions, ensuring a tighter fit and preventing gaps from forming after prolonged friction. Furthermore, the metal... The waste material is not easily pressed into the space between the forming groove and the forming protrusion. Compared with traditional metal balers, this high-precision fully automatic metal waste baler uses a conveyor belt feeding device 1 to automatically feed the material instead of manually feeding it, which saves labor costs and improves feeding efficiency. It also avoids the gaps that may occur after long-term friction between the side push head 9 and the second pressing forming cavity 7, the pressing head 12 and the third pressing forming cavity 10, and the main push head 13 and the main pushing forming cavity, which can cause material jamming. Furthermore, it prevents burrs or sharp edges from forming the bales, thus improving the forming quality of the bales.

[0032] Specifically, the conveyor belt feeding device 1 includes a conveyor frame and a conveyor. The conveyor frame is inclined upwards toward the raw material storage hopper 2, and the conveyor is mounted on the conveyor frame and feeds material into the raw material storage hopper 2. The raw material storage hopper 2 is mounted on a support frame above the pressing chamber 3, which is located above the second pressing and forming cavity 7. The weighing sensor 8 is mounted on the support frame and weighs the metal scrap in the raw material storage hopper 2. Figures 1 to 9As shown, a conveyor belt can be installed on the conveyor, and the conveyor can adopt a conventional conveying structure with pulleys and a motor to drive the conveyor belt, so it will not be described in detail. The metal scrap moves along the conveyor on the conveyor frame to the top of the raw material storage hopper 2, and then the metal scrap falls into the raw material storage hopper 2. The weighing sensor 8 can be a sensing unit that receives signals as a pressure sensor. The raw material storage hopper 2 and the weighing sensor 8 work together to weigh the required weight of metal scrap. After the weight of the metal scrap in the raw material storage hopper 2 reaches the preset value, the weighing sensor 8 feeds back a signal to cut off the power to the conveyor and stop the feeding operation, thereby replacing the manual feeding method, saving labor costs, improving the accuracy of metal scrap weighing, and improving feeding efficiency.

[0033] Furthermore, the two unloaders are correspondingly arranged on the front and rear sides of the raw material storage hopper 2. Each unloader includes two opposing hopper cylinders 14 hinged together, and hopper gate plates 15 are hinged to the left and right sides of the bottom surface of the raw material storage hopper 2. The output end of one hopper cylinder 14 on the front and rear sides of the raw material storage hopper 2 is hinged to one hopper gate plate 15, and the output end of the other hopper cylinder 14 on the front and rear sides of the raw material storage hopper 2 is hinged to the other hopper gate plate 15. A baffle plate 16 is provided on the top surface of the pressing box 3 below the raw material storage hopper 2, and a side pusher cover plate 17 is provided on the side of the side pusher 9 facing the side cylinder 5. Figures 1 to 9 As shown, the side cylinder 5 can be a hydraulic cylinder. After the raw material storage hopper 2 weighs the required metal scrap, the hopper cylinder 14 drives the hopper door plate 15 to open the raw material storage hopper 2. The metal scrap in the raw material storage hopper 2 falls into the second pressing and forming cavity 7, and the hopper cylinder 14 drives the hopper door plate 15 to reset. At this time, the conveyor on the conveyor frame can continue to feed materials. Then, the side cylinder 5 drives the side push head 9 to perform the metal scrap compression work. The side push head cover plate 17 moves along the second pressing and forming cavity 7 with the side push head 9, and the side push head cover plate 17 moves to the bottom of the raw material storage hopper 2. The side push head cover plate 17 closes the bottom of the baffle plate 16. In this way, the required metal scrap is weighed again in the raw material storage hopper 2. After the waste material hopper cylinder 14 drives the hopper door plate 15 to open the raw material storage hopper 2 again, the metal waste in the raw material storage hopper 2 falls into the storage space formed by the side push head cover plate 17 and the baffle plate 16. The side cylinder 5 drives the side push head 9 to press the metal waste into the main push forming cavity 6 for forming. After the side push head 9 completes the extrusion of the metal waste, the side cylinder 5 drives the side push head 9 and the side push head cover plate 17 to reset and open the bottom of the baffle plate 16. The metal waste in the baffle plate 16 falls into the second pressing forming cavity 7 for processing. This cycle is repeated to carry out the feeding work, so that the raw material storage hopper 2 can continuously carry out the feeding work, improving the feeding speed and working efficiency of the raw material storage hopper 2.

[0034] The high-precision fully automatic metal scrap baler of this utility model also includes a main cylinder auxiliary support 18, which is disposed between the main cylinder 4 and the pressing box 3, and the main push head 13 is housed within the main cylinder auxiliary support 18. The main cylinder auxiliary support 18 is a hollow base, and its length is less than the length of the main push head 13. Furthermore, the pressing box 3 has a through groove at the discharge port of the main pushing forming cavity 6 away from the main push head 13, and a baffle gate 19 is slidably connected within the through groove. The high-precision fully automatic metal scrap baler also includes a baffle gate cylinder 20. The baffle gate 19 has an opening, the size of which is larger than the discharge port of the main forming cavity 6. The baffle gate cylinder 20 is disposed adjacent to the baffle gate 19 on the side wall of the pressing box 3, and the output end of the baffle gate cylinder 20 is connected to the baffle gate 19. The high-precision fully automatic metal scrap baler also includes a discharge conveyor frame 21, which is positioned at the location of the baffle gate 19 and is inclined outwards and upwards. Figures 1 to 9 As shown, the main cylinder 4 can be a hydraulic cylinder. After the side push head 9 cooperates with the second pressing and forming cavity 7 to squeeze the metal scrap, the metal scrap reaches below the third pressing and forming cavity 10. The press head cylinder 11 drives the press head 12 to move downward and cooperate with the third pressing and forming cavity 10 to squeeze the metal scrap. Finally, the main cylinder 4 drives the main push head 13 to move from the main cylinder auxiliary support 18 to the main push forming cavity 6, and the main push head 13 cooperates with the main push forming cavity 6 to squeeze the metal scrap. At this time, the opening of the baffle gate 19 is misaligned with the main push forming cavity 6 and blocks the metal scrap so that the metal scrap can be squeezed and formed. As a bale, after the metal scrap is formed, the main cylinder 4 drives the main push head 13 to retreat a certain distance and relieve pressure on the bale. The output end of the bale gate cylinder 20 drives the bale gate 19 to move outward and align the opening with the main push forming cavity 6. Finally, the main cylinder 4 drives the main push head 13 to push the formed bale from the opening to the discharge conveyor frame 21. Then the main push head 13, the side push head 9 and the pressure head 12 are reset. The bale gate cylinder 20 drives the bale gate 19 to reset and repeats this cycle to perform the forming process. The formed bales are arranged in sequence in the discharge conveyor frame 21 for collection, which improves the forming quality of the formed bales.
