Automatic and controllable coil unwinding device

Abstract

The invention discloses an automatic controllable coiled material pay-off device. The device comprises a base, a rack, a coiled material pay-off shaft, a rotating motor, a switching device and a raw material pressure lever, wherein the rack is mounted on the base and fixedly connected with the base; the coiled material pay-off shaft is mounted on the rack; the rotating motor is used for controlling the coiled material pay-off shaft to rotate; the switching device is mounted on the rack; the raw material pressure lever is mounted on the rack and corresponds to the coiled material pay-off shaft; and the raw material pressure lever and the rotating motor are electrically connected with the switching device. The automatic controllable coiled material pay-off device can achieve automatic paying-off and stopping of coiled materials, the method is novel and unique, and the device is low in cost and high in production efficiency, can perform production automatically and synchronously with other machines, and does not need to be guarded by a special person.

Description

technical field [0001] The invention relates to the technical field of die-cutting, in particular to an automatically controllable coil unwinding device. Background technique [0002] In recent years, with the continuous development of electronic technology, electronic products have been constantly updated, and the performance, appearance, and integration of products have been greatly improved accordingly, especially the hot sales of mobile phones, tablet computers and other products. It has also driven the continuous development of manufacturing technology in the electronics industry. The integration level of electronic products continues to increase, which requires more precise and accurate manufacturing techniques for the various components used to assemble electronic products. The continuous replacement and iteration of electronic products also requires that the production capacity of the electronics industry must be continuously improved, which will inevitably require ...

Problems solved by technology

Die-cutting machines are usually divided into two categories: circular knife and flat knife. The cost of the circular knife die-cutting machine is relatively high, and the unwinding of the unwinding roll can be controlled synchronously. However, in many cases, such as when producing larger-sized products, flat knives are still required. Die cutting machine for production

Flat-knife die-cutting machines are usually used in conjunction with coil unwinding machines, compound machines, etc. It is difficult to achieve synchronous, automated and continuous production when multiple machines are used together

[0004] Although the unwinding machine can continuously feed materials, but to achieve synchronous production with other machines, it usually requires a special person to control its start and stop, which is low in efficiency, high in cost and prone to abnormal situations

The Chinese patent with the patent publication number of 202448172U describes an automatic coil unwinding machine, which mainly uses a photoelectric sensor to control the feeding, but the coil film will still be broken at the unwinding shaft, and the structure is complicated and the cost is high. low efficiency
