Description

Technical Field

[0001] The utility model relates to the technical field of aluminum chip recovery, in particular to a hopper type aluminum chip recovery and weighing device. Background Art

[0002] During the wheel hub manufacturing process, machining steps generate a large amount of aluminum chips. These chips are typically collected in a chip handling room for deoiling. They are then transported back to the smelting process via a rotary auger conveyor, where they are fed into the chip furnace as raw material to be melted into molten aluminum, thus recovering the aluminum by-product. The feeding of aluminum chips into the chip furnace has strict requirements on the amount of aluminum chips required. Excessive amounts will not meet production process requirements and affect smelting quality; insufficient amounts will reduce the furnace's output and increase production costs.

[0003] Currently, to obtain the weight of aluminum chips input, operations typically manually calculate the product of the rotating auger conveyor's scheduled flow rate and time to convert the weight. However, the auger conveyor's flow rate is significantly affected by the preceding production load, and its scheduled flow rate is not constant. This often results in a significant deviation between the calculated and actual aluminum chip input weight, causing the aluminum chip input amount to fall short of expectations and seriously affecting the input ratio of the aluminum chip furnace. Furthermore, manually calculating the aluminum chip input weight cannot be uploaded to the production line's MES system for real-time data collection, which affects the statistics and monitoring of production process data.

[0004] Based on this, developing a new type of hopper-type aluminum chip recovery and weighing device for application in actual production is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems and provide a hopper-type aluminum chip recovery and weighing device to solve the problem of inaccurate input measurement in the existing aluminum chip return process, which affects the input ratio of the aluminum chip furnace, and at the same time solve the problem of the existing manual calculation of the aluminum chip input weight, which affects the statistics and monitoring of production process data.

[0010] Preferably, a buffer hopper is provided at the bottom of the collecting hopper for temporarily storing the weighed aluminum chips discharged from the collecting hopper. The buffer hopper is connected to a feeding auger for feeding the aluminum chips in the buffer hopper into an aluminum chip furnace for smelting.

[0011] Preferably, the suspension cable transmission is connected to a lifting winch for lifting and lowering operations of the aggregate hopper.

[0012] Preferably, the buffer hopper is provided with a fixing pin for securing the collection hopper, the fixing pin being fixedly connected to the four corners of the open end of the buffer hopper.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figure 1 As shown, a hopper-type aluminum chip recovery and weighing device includes a collecting hopper 10, the open end of which is arranged corresponding to the incoming feed auger 20 and is used to collect the aluminum chips conveyed by the incoming feed auger 20. The collecting hopper 10 is fixedly connected to the collecting hopper 10, and the hanging steel cable 11 is provided with a weighing sensor 12 for obtaining the weight data of the aluminum chips in the collecting hopper 10. The bottom of the collecting hopper 10 is an openable structure for discharging the weighed aluminum chips.

[0022] When in use, the bottom of the hopper 10 is in a closed state, and the incoming auger 20 continuously transports the aluminum chips generated by the machining process into the hopper 10. The weighing sensor 12 on the suspension cable 11 weighs the weight of the aluminum chips in the hopper 10 in real time. When it approaches the preset weight value, the incoming auger 20 stops transporting. At this time, the weighing sensor 12 obtains the final data of the weight of the aluminum chips in the hopper 10 under static conditions. After the data collection is completed, the bottom of the hopper 10 opens to discharge the weighed aluminum chips. This embodiment provides a weighing sensor 12 on the suspension cable 11 to monitor the weight of the aluminum chips in the hopper 10 in real time when the hopper 10 is suspended, thereby improving the accuracy of the aluminum chip input, improving the problem of poor accuracy of the traditional aluminum chip weight measurement method, affecting the input ratio of the aluminum chip furnace, ensuring the quality of aluminum chip smelting, and suppressing the increase in production costs.

[0023] As a preferred embodiment, the opening and closing mechanism at the bottom of the hopper 10 includes a bottom plate 13 movably connected to the hopper 10. A plurality of support rods 14 for supporting the bottom plate 13 are spaced apart on opposite side walls of the hopper 10. The bottom plate 13 is slidably connected to the support rods 14. The bottom of the hopper 10 is opened or closed by pushing and pulling the bottom plate 13 to slide back and forth on the support rods 14.

[0024] Preferably, the support rod 14 is rotated to connect to the side wall of the collecting hopper 10, so that the support rod 14 rolls and connects to the bottom plate 13 to overcome the sliding friction between the bottom plate 13 and the support rod 14, facilitate the opening and closing action of pushing and pulling the bottom plate 13, alleviate the wear between the bottom plate 13 and the support rod 14, and improve the operating stability and service life of the device.

[0025] Preferably, a buffer hopper 30 is provided at the bottom of the collecting hopper 10 for temporarily storing the weighed aluminum chips discharged from the collecting hopper 10. The buffer hopper 30 is connected to a feeding auger 40 for feeding the aluminum chips in the buffer hopper 30 into the aluminum chip furnace for smelting. The buffer hopper 30 provides a temporary storage space for the aluminum chips, allowing the collecting hopper 10 to continuously perform weighing operations, thereby ensuring operational efficiency.

[0026] Preferably, the suspension cable 11 is connected to a hoisting winch 50 for raising and lowering the collection hopper 10. During aggregate weighing, the hoisting winch 50, via the suspension cable 11, raises the collection hopper 10 toward the incoming auger 20 to facilitate collection of aluminum chips. After aggregate weighing is complete, the hoisting winch 50 lowers the collection hopper 10 toward the buffer hopper 30 to facilitate discharge.

[0027] Preferably, the buffer hopper 30 is provided with fixing pins 31 for securing the aggregate hopper 10. The fixing pins 31 are fixedly connected to the four corners of the open end of the buffer hopper 30. The bottom of the aggregate hopper 10 is provided with retaining positions corresponding to the fixing pins 31, and the retaining positions are recessed into the bottom of the aggregate hopper 10. After the aggregate hopper 10 is weighed, the hoist 50 drives the aggregate hopper 10 down toward the buffer hopper 30. The fixing pins 31 on the buffer hopper 30 are fixed to the retaining positions of the aggregate hopper 10 to ensure the stability of the aggregate hopper 10.

[0028] Preferably, a push-pull cylinder 60 is provided corresponding to the bottom plate 13, which is used to push and pull the bottom plate 13 to complete the opening and closing action of the bottom of the hopper 10. A push-pull through-hole 131 is provided on the bottom plate 13, and a connecting column 61 is provided at the telescopic end of the push-pull cylinder 60 corresponding to the push-pull through-hole 131. The connecting column 61 is plugged into the push-pull through-hole 131. When the hopper 10 falls on the buffer hopper 30, the connecting column 61 of the push-pull cylinder 60 just penetrates the push-pull through-hole 131 of the bottom plate 13. At this time, the push-pull cylinder 60 retracts and pulls the bottom plate 13 away from the hopper 10, completing the opening action of the bottom of the hopper 10; after completing the discharge of aluminum chips, the push-pull cylinder 60 pushes the bottom plate 13 back to complete the closing action of the bottom of the hopper 10. The provision of the push-pull cylinder 60 eliminates the trouble of manually pushing and pulling the bottom plate 13, reducing the intensity of manual labor.

[0029] Preferably, the weighing sensor 12 is communicatively connected to the production line MES system, and the weighing results are uploaded to the MES system in real time, which facilitates the statistics and monitoring of production process data.

[0030] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be deemed to be protected by the present invention.
