Technical Field

[0001] The utility model relates to the technical field of metal briquetting equipment, in particular to an automatic briquetting and discharging system for scrap metal. Background Art

[0002] Scrap steel refers to steel fragments, debris and steel products scrapped from equipment renewal discarded by the metallurgical industry and metal processing industry. It also includes steel packaging containers and scrapped vehicles recovered from urban garbage. Scrap steel is also a resource. Countries around the world have special units engaged in the recycling and utilization of scrap steel. The recycled scrap steel is mainly used for smelting and converted into recycled steel. Some of it is used to produce machinery and equipment or parts, tools and civilian appliances, realizing the circular use of resources. The recycling of scrap steel benefits the country and the people. It can not only save energy and protect the environment, but also avoid excessive consumption burden on the earth.

[0003] At present, the scrap steel recycling process in my country usually includes steps such as impurity removal, crushing, baling and briquetting, and stacking and unloading, which produces recycled scrap steel briquettes that can be reused as production raw materials.

[0004] In the packaging and briquetting process, the metal fragments are generally fed into the storage box of the metal briquetting machine through a conveying mechanism such as a conveyor belt, and then the metal briquetting machine uses the pressure plates on the top and sides to press the metal fragments into a square shape.

[0032] like Figures 1 to 3 As shown, this embodiment provides an automatic briquetting and discharging system for scrap metal, including a metal briquetting machine 1, a feeding assembly is arranged above the opening of the box body 101 of the metal briquetting machine 1, a briquetting conveyor belt 4 is arranged on the side of the metal briquetting machine 1, and an automatic conveying arm 3 is arranged between the metal briquetting machine 1 and the briquetting conveyor belt 4, and the automatic conveying arm 3 includes a vertical rotating shaft 301, and the vertical rotating shaft 301 is fixedly connected to the tail end of a horizontal arm 302, and a lifting module 5 is installed at the front end of the horizontal arm 302, and an electromagnet plate 6 is installed at the bottom of the lifting module 5.

[0033] When the equipment is running, the feeding component pours a certain amount of scrap metal fragments from the top of the box opening of the metal briquetting machine 1 into the box 101 of the metal briquetting machine 1, and then the metal briquetting machine 1 starts to press the scrap metal fragments into a square-shaped metal briquette 9, then the vertical shaft 301 rotates and drives the lifting module 5 at the front end of the horizontal arm 302 to the top of the box 101 of the metal briquetting machine 1, the lifting module 5 descends and starts the electromagnet plate 6, the metal briquette 9 is magnetically adsorbed and lifted, and finally the vertical shaft 301 rotates in the opposite direction and drives the lifting module 5 to the top of the briquetting conveyor belt 4, the lifting module 5 descends and the electromagnet plate 6 is demagnetized, the metal briquette 9 is placed on the briquetting conveyor belt 4 and output forward.

[0034] The feeding assembly includes a horizontal conveyor belt 2, and the output end of the horizontal conveyor belt 2 is flush with the open side wall of the box body 101 of the metal briquetting machine 1. Since the lifting module 5 is set to run above the box body 101, in order to avoid collision and interference between the horizontal conveyor belt 2 and the lifting module 5, the outlet of the conveyor belt needs to be set on the side as much as possible.

[0035] A metal briquetting machine 1 is provided below both left and right ends of the horizontal conveyor belt 2, a bidirectional motor is connected to the horizontal conveyor belt 2 for driving, and a loading assembly 7 is provided above the horizontal conveyor belt 2. Since the metal briquetting machine 1 needs a certain amount of time to press the scrap metal fragments into blocks, a bidirectionally operable horizontal conveyor belt 2 is provided and metal briquetting machines 1 are provided at both ends, so that the scrap metal fragments can be alternately conveyed to the metal briquetting machines 1 on both sides, thereby accelerating the conveying speed of the scrap metal fragments and improving work efficiency.

[0036] The lifting module 5 includes a vertical lifting rod 501, which is movably sleeved on the front end of the horizontal arm 302, and the electromagnet plate 6 is installed at the bottom of the vertical lifting rod 501. The lifting module 5 with the vertical lifting rod 501 structure has a relatively stable support and a high structural strength, which can ensure the stable grasping of the metal pressing block 9.

[0037] The vertical lifting rod 501 is sleeved with an inner rotating shaft 502, and the electromagnet plate 6 is installed at the bottom of the inner rotating shaft 502. In order to reduce the space occupied by the equipment, the angle at which the automatic conveying arm 3 rotates from the metal briquetting machine 1 to the briquetting conveyor belt 4 is generally less than 90°, that is, it cannot be guaranteed that when the metal briquetting 9 is grabbed onto the briquetting conveyor belt 4, the side of the metal briquetting 9 remains parallel to the briquetting conveyor belt 4. Therefore, a rotatable electromagnet plate 6 is provided to rotate and adjust the orientation of the metal briquetting 9 when the metal briquetting is placed on the briquetting conveyor belt 4, so that it is correctly placed on the briquetting conveyor belt 4.

[0038] A lifting rack 503 is disposed on the side of the vertical lifting rod 501, and the lifting rack 503 is driven and connected to a lifting gear 504. The vertical lifting rod 501 driven by the lifting rack 503 is more stably positioned and has a stronger bearing capacity.

[0039] The rear side of the horizontal arm 302 is connected with a counterweight 8. Since the weight of the lifting module 5 is relatively large, the counterweight 8 is provided to balance the weight of the front and rear sides of the horizontal arm 302 to prevent the horizontal arm 302 from tilting.

[0040] A support oblique arm 303 is connected to the front side of the connection between the horizontal arm 302 and the vertical rotating shaft 301. The support oblique arm 303 can further improve the structural stability of the horizontal arm 302.

[0041] The vertical shaft 301 is rotatably sleeved in the cylindrical support 304, the top end of the supporting oblique arm 303 is fixedly connected to the bottom of the horizontal arm 302, and the tail end of the supporting oblique arm 303 is rotatably sleeved on the outside of the cylindrical support 304 through the collar 305. Since the vertical shaft 301 needs to support the entire automatic conveying arm 3 while driving the horizontal arm 302, in order to ensure the safety of the equipment and avoid the automatic conveying arm 3, the cylindrical support 304 and the supporting oblique arm 303 with the collar 305 are provided to ensure the support stability of the vertical shaft 301.

[0042] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
