This utility model provides an automatic weighing device for preventing the diffusion of carbon black in tire production, belonging to the field of carbon black production technology. The device includes a storage cylinder, a weighing cylinder, a sealing cap, and a conveying pipe. The storage cylinder is shaped like an inverted frustum, with a rectangular outlet at its bottom. The weighing cylinder is positioned below the storage cylinder, with a rectangular inlet at its top corresponding to the outlet at the bottom. The weighing cylinder is cylindrical. The sealing cap is connected to the bottom of the storage cylinder via a hinge shaft, the axis of which is parallel to the long side of the rectangular outlet. The sealing cap is used to open or close the rectangular outlet at the bottom of the storage cylinder. One end of the conveying pipe is connected to the side wall of the weighing cylinder, and the conveying pipe is L-shaped. The other end of the conveying pipe extends downwards at an angle. This utility model solves the problem in the prior art where carbon black weighing during tire production causes carbon black dust to diffuse into the surrounding environment, resulting in additional production costs and safety hazards.

The present application relates to the technical fields of wire twisting, and provides a multi-strand wire twisting forming device, which comprises a base, a vertical fixing seat fixedly connected to the top of the base, a general controller fixedly connected to the top of the base, and a sliding groove formed in the top of the base; a twisting structure, which comprises a driving assembly, a quick-mounting assembly and a guide assembly, the driving assembly being arranged inside the vertical fixing seat, and the guide assembly being arranged on the side of the driving assembly; and a cooling assembly located on the side of the vertical fixing seat.The multi-strand wire twisting forming device provided by the present application realizes the branch guiding and concentrated current collection of the multi-strand wire through the guide assembly, buffers the tension fluctuation through the elastic air bag and the wear-resistant self-lubricating structure, reduces the surface friction, cooperates with the micro-arc-shaped flow guide groove on the inner side of the elastic air bag to reduce the contact resistance, improves the wire feeding smoothness, realizes the wire guiding without crossing, winding and scratching, and completely solves the problems of wire guiding damage and uneven tension.
