Description

Technical Field

[0001] This utility model relates to the field of scrap steel recycling technology, and in particular to a briquetting device for scrap steel recycling. Background Technology

[0002] The scrap steel recycling briquetting device uses a hydraulic system as its core power source, applying high pressure (thousand-ton-level pressure system) to compress loose scrap steel into shape through a mold. The scrap steel recycling process typically includes four stages: feeding, pre-compression, final compression, and discharge. An existing patent (publication number: CN220808633U) discloses a briquetting device for scrap steel recycling. This invention improves work efficiency by setting a discharge component on the worktable and using an electromagnet to quickly remove the processed scrap steel from the compression chamber. However, in practical applications, scrap steel may leave fragments in the compression chamber after briquetting. As processing continues, these fragments accumulate in the chamber, hindering the processing of other scrap steel and affecting practical application. Therefore, we propose a briquetting device for scrap steel recycling. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a briquetting device for scrap steel recycling.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a briquetting device for scrap steel recycling, including a frame with a rotary conveyor mechanism, on which multiple briquetting boxes are conveyed. A pressing mechanism is provided above the rotary conveyor mechanism, and a unloading mechanism is provided on one side of the pressing mechanism. The unloading mechanism includes a cylinder that is slidably connected to the frame. A lifting plate is connected to the stroke end of the cylinder. An electromagnetic plate is provided at the bottom of the lifting plate. A tilting mechanism is provided on the other side of the pressing mechanism. The tilting mechanism includes an assembly frame that moves up and down. A support arm that can be tilted up and down is installed on one side of the assembly frame. Multiple lifting suction cups are installed on the side of the support arm near the briquetting box.

[0006] In the above scheme, the rotary conveying mechanism includes a pair of sprockets rotatably mounted on the frame, a chain connecting the sprockets, a drive connection between the sprockets and a servo motor, an annular guide rail outside the chain, a slide table slidably connected to the annular guide rail mounted on the chain, and the pressure box located on the slide table.

[0007] In the above scheme, a limit plate is fixed on the slide.

[0008] In the above scheme, the pressing mechanism includes a hydraulic cylinder mounted on the frame, and the piston rod of the hydraulic cylinder is connected to a pressure plate adapted to the pressure box.

[0009] In the above scheme, the top of the frame is provided with a linear reciprocating motion mechanism, which includes an mounting groove in which a lead screw is rotatably mounted, a sliding seat is threadedly connected to the lead screw, the lead screw is driven by a servo motor, and the cylinder is connected to the sliding seat.

[0010] In the above scheme, a belt weighing machine is installed on the frame below the electromagnetic plate, a collection box is provided on the belt weighing machine, and a conveyor is provided at the end of the belt weighing machine.

[0011] In the above scheme, a cylinder two with its stroke end pointing downwards and connected to the assembly frame is installed on the top of the frame, and an electric push rod is movably connected between the side of the assembly frame away from the pressure box and the bottom end of the support arm.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a pressing mechanism and a unloading mechanism, the scrap steel is first pressed using a pressing box and a pressing plate, and then the processed scrap steel in the pressing box is adsorbed using an electromagnetic plate, thereby completing the unloading and improving work efficiency. By setting up a rotary conveyor mechanism and a slide table, using sprocket and chain drive, and cooperating with a ring guide rail, the slide table moves back and forth along the ring guide rail, thereby enabling stable conveying of the pressing box between the pressing, unloading and tilting positions. Compared with the prior art, continuous cyclic operation can be performed, significantly improving work efficiency and practicality. By setting up a tilting mechanism, the assembly frame is moved downward using cylinder two, thereby bringing the support arm to the working position. Then, in conjunction with the lifting suction cup, the pressing box is tilted. After adsorption, the assembly rack is moved upwards appropriately, and then the electric push rod is activated to shorten its piston rod, causing the pressure box opening to flip downwards, thus inverting the pressure box and dumping out the processing residue inside. Compared with existing technologies, this method not only removes the residue from the pressure box in a timely manner, preventing accumulation and reducing cleaning difficulty, but also avoids the residue affecting the processing effect. By setting up a collection box, a belt weighing machine, and a conveyor, the electromagnetic plate places the adsorbed recycled steel into the collection box. The belt weighing machine is used to weigh the collection box. When a certain weight is reached, the conveying function of the belt weighing machine is activated, moving the collection box onto the conveyor, which then transports it to the storage area. This reduces manual intervention and achieves the effect of automatic weighing, sorting, and continuous transfer. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a briquetting device for scrap steel recycling, including a frame 1 equipped with a rotary conveying mechanism, on which multiple briquetting boxes 8 are conveyed;

[0022] In more detail, the rotary conveying mechanism includes a pair of sprockets 3 rotatably mounted on the frame 1, a chain 4 connected between the sprockets 3, the sprockets 3 being driven by a servo motor 5, an annular guide rail 2 being provided outside the chain 4, a slide table 6 being mounted on the chain 4 and slidably connected to the annular guide rail 2, and a pressure box 8 being located on the slide table 6.

[0023] Furthermore, a limit plate 7 is fixed on the slide table 6 to position the pressure box 8. In conjunction with a robotic arm equipped with a machine vision mechanism, scrap steel is placed into the pressure box 8, reducing manual operation and lowering the intensity of human labor.

[0024] Specifically, by setting up a rotary conveyor mechanism and a slide table 6, using sprockets 3 and chains 4 for transmission, and cooperating with the annular guide rail 2, the slide table 6 moves back and forth along the annular guide rail 2, thereby enabling the pressure box 8 to be stably conveyed between the pressing, unloading and tilting stations. Compared with the existing technology, with the help of a robot, continuous cyclic operation can be performed, significantly improving work efficiency and increasing practicality.

[0025] A pressing mechanism is provided above the rotary conveyor, and a unloading mechanism is provided on one side of the pressing mechanism. The unloading mechanism includes a cylinder 12 that is slidably connected to the frame 1. A lifting plate 13 is connected to the stroke end of the cylinder 12. An electromagnetic plate 14 is provided at the bottom of the lifting plate 13. Multiple electromagnets are installed inside the electromagnetic plate 14 to generate magnetism and adsorb the processed scrap steel.

[0026] Furthermore, the pressing mechanism includes a hydraulic cylinder 9 mounted on the frame 1. The piston rod of the hydraulic cylinder 9 is connected downward to a pressure plate 10 that is compatible with the pressure box 8. Through the hydraulic cylinder 9 and the pressure plate 10, pressure is applied to the scrap steel located in the pressure box 8, thereby completing the processing.

[0027] Specifically, by setting up a pressing mechanism and a unloading mechanism, the scrap steel is first pressed using the pressing box 8 and the pressing plate 10, and then the processed scrap steel in the pressing box 8 is adsorbed using the electromagnetic plate 14, thereby completing the unloading and improving work efficiency.

[0028] Furthermore, the top of the frame 1 is provided with a linear reciprocating motion mechanism 11. The linear reciprocating motion mechanism 11 includes a mounting groove 111 in which a lead screw 112 is rotatably mounted. A sliding seat 113 is threadedly connected to the lead screw 112. The lead screw 112 is connected to a servo motor 114 for transmission. A cylinder 12 is connected to the sliding seat 113.

[0029] Furthermore, a belt weighing machine 16 is installed below the electromagnetic plate 14 and mounted on the frame 1. A collection box 15 is provided on the belt weighing machine 16, and a conveyor 22 is provided at the end of the belt weighing machine 16.

[0030] Specifically, by setting up a collection box 15, a belt weighing machine 16, and a conveyor 22, the electromagnetic plate 14 places the adsorbed recycled steel into the collection box 15. The belt weighing machine 16 is used to weigh the collection box 15. When a certain weight is reached, the conveying function of the belt weighing machine 16 is activated, so that the collection box 15 moves onto the conveyor 22, and is then transported by the conveyor 22 to the storage area. This reduces manual intervention and achieves the effect of automatic weighing, sorting, and continuous transfer.

[0031] On the other side of the pressing mechanism is a tilting mechanism, which includes an assembly frame 18 that moves up and down. A support arm 19 that can be flipped up and down is installed on one side of the assembly frame 18. The top of the support arm 19 is connected to the assembly frame 18 through a pivot. Multiple lifting suction cups 20 are installed on the side of the support arm 19 near the pressure box 8. The lifting suction cups 20 can be either electromagnetic suction cups or vacuum suction cups. The lifting suction cups 20 are used to lift the pressure box 8 to reduce damage to the pressure box 8.

[0032] Furthermore, a cylinder 17 with its stroke end pointing downwards and connected to the assembly frame 18 is installed on the top of the frame 1. An electric push rod 21 is movably connected between the side of the assembly frame 18 away from the pressure box 8 and the bottom end of the support arm 19. The electric push rod 21 with its stroke end pointing downwards is connected to the support arm 19. By controlling the length of the electric push rod 21, the angle between the support arm 19 and the assembly frame 18 is adjusted, thereby adjusting the posture of the pressure box 8 so as to switch it between the opening downwards and the opening upwards.

[0033] Specifically, by setting up a tilting mechanism, the cylinder 17 drives the assembly frame 18 to move downward, thereby bringing the support arm 19 to the working position. Then, in conjunction with the suction cup 20 of the lifting device, the pressure box 8 is adsorbed. After that, the assembly frame 18 is moved upward appropriately, and then the electric push rod 21 is activated to shorten its piston rod, causing the opening of the pressure box 8 to flip downward, thereby inverting the pressure box 8 and pouring out the processing residue inside. Compared with the existing technology, this method can not only remove the residue inside the pressure box 8 in a timely manner, preventing accumulation and reducing cleaning difficulty, but also avoid the residue affecting the processing effect.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
