Description

Technical Field

[0001] This utility model relates to the field of protection technology, specifically a shrinking machine with protective function. Background Technology

[0002] A necking machine is a plastic processing machine used to reduce the opening of plastic bottles, cans, and other containers. Its working principle is mainly based on the heating and cooling process of plastic. The necking machine consists of a feeding device, a heating device, a compression device, and a cooling device. First, the feeding device feeds the plastic container into the heating device, where it is heated to a plastic state using electromagnetic heating or infrared heating. Then, the compression device reduces the opening of the container, sealing it. Finally, the cooling device rapidly cools the necked container, fixing its shape. The advantages of a necking machine are its high efficiency, energy saving, environmental friendliness, and ease of operation. In addition, necking machines are also used for the reduction and forming of metal pipes. For example, a steel pipe necking machine uses mechanical transmission to rotate the steel pipe, and heats one end of the pipe with a flame. When the appropriate temperature is reached, a forming mold is used to shape the heated end of the pipe until the desired shape is achieved. This type of necking machine eliminates the need for traditional welding processes, completing the butt joint by proportionally shrinking galvanized pipes, which not only improves efficiency but also ensures coaxiality after the butt joint. In summary, the necking machine is not only suitable for sealing plastic containers, but also widely used in the necking and forming of metal pipes. It achieves its function through different working principles and technologies. In the existing technology, during the clamping process, the necking machine may cause the workpiece to bend and be damaged due to low support. At the same time, during the necking process, people around may accidentally touch the processing area of ​​the equipment and be injured. During the high-speed rotation of the necking machine mold, some debris may also be generated, which may affect the surrounding personnel. Therefore, this utility model proposes a necking machine with protective function. Utility Model Content

[0022] By setting the movable block 5, the longitudinal height of the fixed fixture 14 can be adjusted so that it can adapt to the processing size of different shrinking machines. The movable block 5 is connected to the end face of the shrinking machine fixture through the slide rail and can slide up and down. After the position is determined, the screw column is rotated and fed inward by rotating the locking handle 7 to form a compression fixation with the inside.

[0023] A fixed frame 6 is provided on the end face of the movable block 5. The upper end of the fixed frame 6 is connected to symmetrically distributed fixed clamps 14 via a slide rail. The fixed clamps 14 are connected to each other via threaded pins and threaded holes. An adjustment handle is provided on the end face of the threaded pin. The fixed frame 6 is welded to the end face of the movable block 5, and the adjustment handle is welded to the end face of the threaded pin.

[0024] By setting up the fixed fixture 14, the workpiece is assisted in clamping and bending is avoided during the necking process. A set of fixed fixtures 14 are connected by threaded columns. When the threaded columns are rotated by rotating the handle, they can move in opposite directions to achieve the clamping effect.
