Description

Technical Field

[0001] This utility model relates to a metal scrap patty press machine. Background Technology

[0002] To facilitate storage and reduce environmental pollution, many companies now process iron filings into briquettes. This not only reduces the footprint of the same weight of iron filings, making them easier to transport and store, but also allows the lubricating oil on the iron filings to be recycled and reused.

[0003] Existing iron scrap briquetting machines generally consist of a feeding device and a briquetting device, which are not integrated. Furthermore, the feeding device is relatively large, significantly increasing space requirements and making it unsuitable for small or narrow spaces. Transportation is also cumbersome. For example, the iron scrap briquetting system disclosed in publication number CN107309060A has too large a footprint and is unsuitable for small and medium-sized enterprises. Additionally, existing briquetting devices typically include a shredding device, a conveying device, and a pressing device. The shredding device cuts the iron scrap into granules, and the conveying device transports the shredded iron scrap to the pressing device. The device compresses the material; however, the conveying device of existing iron scrap briquetting machines is generally composed of a push plate driven by a cylinder. This results in a large error in the amount of iron scrap conveyed to the pressing bin. At the same time, existing pressing devices generally compress the material directly through the pressure plate. Due to the lack of an exhaust design, the oil removal rate and the compression rate are not ideal. Insufficient compression can easily cause the iron scrap blocks to rust, affecting the revenue from subsequent scrap sales. Moreover, existing briquetting machines have only one discharge port, while there are many types of iron scrap. Some need to be cut into iron scrap, while others can be directly compressed. Therefore, the structural design is not reasonable. Utility Model Content

[0004] In view of the shortcomings of existing iron scrap briquetting machines, the technical problem to be solved by this utility model is to provide an iron scrap briquetting machine with a compact and reasonable structure, accurate feeding, and ideal oil removal rate and compression rate.

[0005] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a scrap metal briquetting machine, comprising: a frame, wherein the frame is provided with a shredding mechanism, a feeding mechanism, and a pressing device.

[0006] The shredding mechanism includes a hopper with a hollow top opening to form a storage space. The lower end of the storage space has a discharge port, and a partition that can rotate back and forth is provided in the center of the discharge port. The partition makes the discharge port form two openings, and two shredding blades that cross each other and can rotate in opposite directions are provided in one of the openings. The shredding blades are used to shred the iron filings.

[0007] The feeding mechanism includes a feeding frame and a power unit. One end of the feeding frame is located at the upper end of the storage space, and the other end is set close to the ground. The feeding frame is provided with opposing slide grooves. Each slide groove is provided with a roller that can roll along the slide groove. The two rollers are connected by a connecting rod, and a trolley fixing frame is sleeved on the connecting rod. The trolley fixing frame is used to fix the trolley. The power unit serves as the power source for raising and lowering the trolley fixing frame, so that the two rollers slide along the slide groove.

[0008] The pressing device includes a feeding bin, a briquetting bin, and an oil storage bin. The feeding bin is located below the feeding port and contains an auger driven by an auger conveyor motor. One side of the briquetting bin is connected to the feeding bin to receive the debris conveyed by the auger. Hydraulic presses and discharge ports are located on opposite sides of the feeding bin. A baffle is also provided on the briquetting bin on the discharge port side. The baffle is raised and lowered by a cylinder to close the discharge port. A pressure plate is also provided on the pressure shaft of the hydraulic press. The pressure plate has several spherical extrusion heads. The briquetting process is carried out by the cooperation of the pressure plate and the baffle. The oil storage bin is located at the lower end of the briquetting bin and has several small oil leakage holes on the lower surface of the briquetting bin.

[0009] Furthermore, the feeding rack includes two support frames, each of which is fixed to the machine frame by a fixing rod on both sides. Two swing rods are provided between the two support frames via a rotating shaft. Each of the two swing rods is also pinned to a pull rod on the side near the trolley fixing frame. The lower end of the pull rod is hinged to the trolley fixing frame. A cylinder is also provided on each side of the rotating shaft and is hinged to the support frame.

[0010] Furthermore, the trolley fixing frame is a quadrilateral frame, and the trolley fixing frame is provided with two connecting rods, and each connecting rod has rollers at both ends that can roll along the slide groove.

[0011] Furthermore, a number of reinforcing rods are provided at intervals between the two support frames.

[0012] Furthermore, the power unit comprises a shredding motor, a gearbox, and a coupling, which are connected in sequence, and the coupling is connected to the shredding blade. At the same time, the shredding motor and gearbox are arranged at right angles to the shredding blade.

[0013] Furthermore, the lower end of the partition is provided with a rotating shaft, and the two sides of the rotating shaft are connected to the hopper through bearings. A gear is also provided on one side of the rotating shaft, and a toothed plate is provided on the frame at the lower end of the gear. The toothed plate meshes with the gear and is driven to move back and forth by a push cylinder.

[0014] Furthermore, a pulley is provided on the outer side of the auger, and a pulley is also provided on the motor shaft of the auger conveyor motor. The two pulleys are connected by a belt.

[0015] Furthermore, the plurality of spherical extrusion heads are arranged in a circular or quadrilateral array.

[0016] Furthermore, the discharge port is provided with a downwardly inclined discharge plate.

[0017] Compared with the prior art, the advantages of this utility model are as follows: by directly setting the feeding mechanism on the frame, the overall structure is more compact and the size of the whole machine is not greatly increased. At the same time, feeding is also convenient. In addition, the partition forms two openings at the discharge port, and the shredding blade is set at only one opening. This allows for selective feeding through the partition. The design of the auger and several spherical extrusion heads not only makes the feeding more precise, but also has an exhaust space between the two extrusion heads, making the oil removal more thorough.
