Description

Technical Field

[0001] The utility model relates to a coil winding device, especially applied in the manufacturing field of polymer coil winding equipment. Background Art

[0002] The descriptions in this section only provide background information related to the present disclosure and do not constitute prior art.

[0003] Synthetic polymer waterproof coils are rollable sheet waterproof materials made with synthetic rubber, synthetic resin or a blend of both as the base material, adding appropriate chemical additives and fillers, etc., and using rubber or plastic processing techniques such as mixing, extrusion or calendering.

[0004] The coil winding device winds the coils (such as synthetic polymer waterproof coils) into coils through a winding roller. The existing coil winding devices (as shown in Figure 12 ) have the following defects: 1. There is no limit structure at the end of the winding roller of the existing coil winding device, so that during the winding process, the end face of the finished coil is likely to be uneven, thus affecting the winding quality; 2. The length of the existing winding roller is fixed and cannot flexibly adapt to the winding of coils with different widths. If the winding roller with a different length needs to be replaced, the winding roller has to be removed from the base, reinstalled after replacement, and the operation is very troublesome. Moreover, in order to adapt to the winding of coils with different widths, winding rollers with different lengths must be processed, which is not only costly but also very inconvenient for production, processing and operators.

[0005] Therefore, it has become an urgent matter to provide a coil winding device with a simple structure, convenient operation, capable of ensuring the flatness of both end faces of the wound product, capable of flexibly adjusting the length of the winding roller to wind coils with different widths, and capable of being quickly installed or disassembled.
