Description

Technical Field

[0001] The utility model relates to the technical field of automatic recycling of factory waste, and particularly relates to an automatic blanking waste recycling system for core stamping production. Background Art

[0002] The blanking process of silicon steel sheets is involved in core stamping production. In production, a punching machine and a blanking die are usually used to achieve the blanking process of silicon steel sheets. In large-scale production, a dedicated core blanking production workshop is usually set up, and a large number of punching machines are arranged in the production workshop. However, due to a large amount of blanking waste generated during the blanking process, the blanking waste will be scattered around the site of each punching machine, bringing certain challenges to the cleaning management of the production site. The traditional method for cleaning and managing the blanking waste in the workshop is to arrange a certain number of cleaners to clean and collect the waste blanked from the punching machines regularly or irregularly every day. However, due to the large number of punching machines arranged in the production workshop and the continuous blanking process of the punching machines, this method for cleaning and managing the blanking waste cannot completely avoid the accumulation and pollution of the blanking waste in the production site, and also brings a relatively high cost for personnel cleaning and maintenance.

[0003] Therefore, it is necessary to technically improve the existing blanking waste collection method to solve the above problems. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an automatic blanking waste recycling system for core stamping production, aiming to realize the automatic recycling of blanking waste in the production workshop, improve the cleanliness of the production site, and reduce the personnel cleaning and maintenance cost of the production site.

[0020] The beneficial effects of the present utility model are as follows:

[0021] First, for the blanking waste automatic recovery system for iron core stamping production of the present utility model, by means of the blanking waste collection channel located below the ground of the iron core stamping workshop and the inclined chute connecting the blanking opening of the punching machine and the blanking waste collection channel, the blanking waste punched by the punching machine can be immediately introduced into the first conveyor arranged in the blanking waste collection channel, and then the blanking waste is centrally collected through the transfer of the second conveyor. Thus, the automatic recovery of the blanking waste in the production workshop can be realized, the cleanliness of the production site can be improved, and the personnel cleaning and maintenance cost of the production site can be reduced.

[0022] Second, for the blanking waste automatic recovery system for iron core stamping production of the present utility model, the blanking waste is directly discharged outside the iron core stamping workshop through the wall-piercing pipeline passing through the wall, which facilitates the transport vehicle to directly transport the blanking waste out, and improves the efficiency of the automatic collection and treatment of the blanking waste.

[0023] Thirdly, for an automatic blanking waste recycling system for iron core stamping production of the present utility model, a material level detection device is also provided on the first conveyor (scraper conveyor). The stop or operation of the first conveyor and the second conveyor is determined by the real-time detection result of the material level height in the chute by the material level detection device, so that the first conveyor and the second conveyor do not need to operate continuously. Therefore, the energy consumption of the first conveyor and the second conveyor is greatly reduced, and it has a good effect of energy conservation and environmental protection.
