[0002] With the continuous increase in the number of cars in use, the number of scrapped cars is also increasing year by year. If scrapped cars are not handled properly, they will cause serious pollution to the environment. However, through reasonable dismantling and recycling, the negative impact of scrapped cars on the environment can be reduced. After dismantling scrapped cars, a large amount of metal recycling resources can be obtained, which reduces the production pressure of the original metal raw material output, realizes the utilization of recycled resources, thereby reducing production costs and improving economic benefits. In the recycling of scrap metals, most people will choose to recycle them, but the shapes of scrap metals are different and scattered, which often brings difficulties to recycling, transportation, storage and recycle. In order to adapt to the feeding of the refining equipment of downstream enterprises and save storage and transportation space, the scrap metal raw materials need to be pre-processed by briquetting and packaging.

[0003] The briquetting and packaging process involves the quantitative transfer, pit pushing and briquetting of scrap metal sheets. Usually, a steel grabber is used to transfer the stacked scraps, and then the appropriate amount of material is pushed into the pit manually based on experience for briquetting. The whole process generates a lot of noise, is labor-intensive, and cannot accurately control the amount of material, and has certain safety hazards. Therefore, it is necessary to transform the existing production line and realize the feeding and briquetting of scrap metal sheets through automation. Summary of the invention

[0025] The utility model is further described below in conjunction with embodiments:

[0026] like Figure 1-Figure 2 As shown, the automatic briquetting and packaging system for scrap metal processing of the utility model is mainly composed of a double-beam crane 2, a silo 3, a conveyor belt 4, a dump truck 5, a track 6 and a plurality of balers 7.

[0027] The double-beam crane 2 is located in the light and thin material area, and is provided with an electromagnetic disk 1. The electromagnetic disk 1 is suspended on the main hook of the double-beam crane 2, and the horizontal position and height of the electromagnetic disk 1 can be controlled by remote control. The lower end of the electromagnetic disk 1 is a temporary storage area for materials. When powered on, the magnetic force can adsorb the metal materials in the temporary storage area to the electromagnetic disk 1. The electromagnetic disk 1 is transferred to a designated position by remote control, and then the electromagnetic disk 1 is powered off, and the metal materials adsorbed on the electromagnetic disk 1 fall down. Specifically, the electromagnetic disk 1 is moved to the top of the silo 3 with the vibrator 9, and then the electromagnetic disk 1 is powered off, so that the materials fall into the silo 3.

[0028] The silo 3 is located below the double-beam crane 2. The feed inlet on the top of the silo 3 is rectangular and has a closed opening on the bottom. The silo 3 is tilted at an angle of about 20°. A vibrator 9 is installed below the outer side of the silo 3 to realize the vibration function of the silo 3, so that the material body can fall onto the conveyor belt 4. The PLC automatic control system is connected to the motor control of the vibrator 9 of the silo 3. The PLC automatic control system can send control instructions to the motor to control its operation and make the silo 3 vibrate.

[0029] A conveyor belt 4 is arranged below the silo 3, with the starting end of the conveyor belt 4 below the discharge port of the silo 3 and the terminal end at the designated position reached by the dump truck 5. The conveyor belt 4 rotates to transfer the material to the dump truck 5. Specifically, the terminal of the conveyor belt 4 is above the dump truck, which is convenient for transporting the material to the dump truck. The PLC automatic control system is connected to the control of the conveyor belt 4 and can send control instructions to the conveyor belt 4 to control its operation or stop.

[0030] The dump truck 5 runs on a track 6 built on a 2-meter-high platform 8. A position sensor is provided on the track 6. When loading, the dump truck 5 moves to a specified position.

[0031] In the utility model, the section below the discharge port of the silo 3 is the starting section, and the section until the material body is transported to the dump trolley 5 is the terminal section. A weighing sensor is installed on the dump trolley 5, so that the trolley has a weighing function. The weighing sensor is connected to the PLC automatic control system, which can collect weight data and convert it into an electrical signal and transmit it to the PLC automatic control system. The PLC automatic control system can also send a position movement instruction to the dump trolley 5.

[0032] The baler 7 includes an upper cover, four hydraulic cylinders and a discharge door. Among them, two hydraulic cylinders are used to control the opening and closing of the upper cover and the discharge door respectively. Specifically, the upper cover is connected to the hydraulic cylinder I through a metal shaft, and the discharge door is connected to the hydraulic cylinder II.

[0033] Hydraulic cylinder III is used to push the material and press the blocks. It can clamp the material into blocks and push the material again to push it out after the discharge door is opened.

[0034] The hydraulic cylinder IV is arranged in a direction perpendicular to the direction of the main cylinder and is used to compress the material in another direction.

[0035] In the utility model, after the upper cover is closed, the thickness of the material body can be compressed and limited, and then the material body is compressed in two directions on the horizontal plane by hydraulic cylinder III and hydraulic cylinder IV to limit the length and width of the material body.

[0036] The baler 7 is also provided with a pit to accommodate the material body, and a discharge door is arranged on the side of the pit on the baler 7, and the discharge door is connected to the hydraulic cylinder. The upper surface of the baler 7 is flush with the platform 8, that is, the upper cover is flush with the platform 8 after closing.

[0037] The PLC automatic control system is connected to each baler 7. When the PLC sends a command to the baler 7, the baler 7 starts the baling procedure. After the upper cover hydraulic cylinder is closed, the upper cover is opened. At this time, the PLC sends a command to the tipping trolley 5. The tipping trolley 5 flips the material in the tipping bucket into the pit of the baler 7. After the material enters the pit, the hydraulic cylinder I extends, the upper cover is closed, and then the metal is packed and pressed into blocks through the thrust of the hydraulic cylinder III and the hydraulic cylinder IV. The discharge door is contracted through the connected hydraulic cylinder II, the small door is opened, and the metal block is pushed out through the hydraulic cylinder III. Each baler 7 is equipped with a position sensor corresponding to the track 6 position, which is used to collect the position information of the tipping trolley 5 and transmit the electrical signal to the PLC automatic control system, so that the trolley tipping bucket can tip the material into the pit of the baler 7.

[0038] The working process of the above-mentioned automated briquetting and packaging system for scrap metal processing:

[0039] 1. Feeding

[0040] The weighing sensor on the dump trolley 5 converts the data of weight 0 into an electrical signal and transmits it to the PLC automatic control system, which then sends a position movement instruction to the dump trolley 5. When the position sensor detects that the trolley has reached position 0, it transmits the electrical signal to the PLC automatic control system. At this time, the PLC automatic control system sends an operation instruction to the silo 3 and the conveyor belt 4 motor, the conveyor belt 4 starts to operate, and the silo 3 starts to vibrate. At this time, the operator can use the remote control to power on the electromagnetic disk 1 on the double-beam crane 2, control the position and rise and fall of the electromagnetic disk 1 to facilitate the adsorption of the material body, and then move the electromagnetic disk 1 to the top of the vibrating silo 3, control the electromagnetic disk 1 to be powered off, and the material body falls into the silo 3. As the silo 3 vibrates, the material body falls onto the conveyor belt 4, and then through the rotation of the conveyor belt 4, the material body is conveyed to the dump trolley 5 below the terminal position. The number of dump trolleys 5 and balers 7 can also be increased or decreased according to actual needs, and the corresponding operating program can be set to complete the loading and packaging.

[0041] 2. Transshipment

[0042] The weighing sensor on the tipping trolley 5 collects weight data and converts it into an electrical signal and transmits it to the PLC automatic control system. When the weight reaches the set value, the PLC automatic control system sends instructions to the conveyor belt 4 and the silo 3 motor, and the operation stops. At the same time, a movement instruction to position 1 is sent to trolley No. 1. When the position sensor detects that the trolley has reached position 1, the PLC automatic control system sends instructions to the trolley and the baler 7, the trolley stops running, and the upper cover of the baler 7 is opened. When the PLC receives the position data of the upper cover of the baler 7, it sends instructions to the trolley again, and the trolley turns the material in the bucket into the pit of the baler 7. The weighing sensor in the car converts the weight data into an electrical signal and sends it to the PLC automatic control system. When the data is detected to be 0, instructions are sent to the trolley and the baler 7 respectively, the trolley tipping bucket is reset, and the upper cover of the baler 7 is closed. In this embodiment, one trolley and three balers 7 are set, and each baler 7 is provided with a position sensor at the corresponding position of the track 6. The trolley feeds materials alternately in the order of positions 0-1-0-2-0-3 according to the program setting.

[0043] 3. Packaging

[0044] After the upper cover of the baler 7 is closed, the hydraulic cylinders III and IV are started, and after the material body is baled and pressed into blocks, the upper cover is automatically opened, and the blocks are pushed out to the temporary storage area to complete the baling.

[0045] The utility model sets the height of the platform 8 at 2 meters, which is convenient for the maintenance of the baler 7 below.
