In this way, the interval between the unwinding of the plastic film and the replacement of the new roller to continue the unwinding process is long, resulting in a lack of material in the production line, and the connection is not compact, which in turn leads to low production efficiency.

Embodiment Construction
[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a film unwinding and material changing device based on constant-speed unwinding of an unwinding roller. The film unwinding and material changing device comprises a supportingframe, the unwinding roller and a material changing reminding mechanism, wherein the unwinding roller is rotationally arranged on the supporting frame and detachably connected with the supporting frame, the material changing reminding mechanism is arranged on the supporting frame and above the unwinding roller. According to the film unwinding and material changing reminding device based on constant-speed unwinding of the unwinding roller, material changing reminding of different levels is conducted according to the quantity of plastic films left on the unwinding roller, so that workers are reminded to conduct material changing in time, machining connection of the plastic films is compact, and then the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of plastic film processing, in particular to a film unwinding and refueling reminder device based on unwinding rollers unwinding at a constant speed. Background technique [0002] Plastic film is a long, wide film structure that is usually stored on a roll. When it needs to be used, it can be unrolled and used by unwinding. However, due to its long, wide, and thin structural characteristics, the plastic film is prone to wrinkles during winding and unwinding. [0003] In addition, plastic films are often used on production lines. When the unwinding of a single roll of plastic film is completed, it cannot be found in time that the unwinding is completed and the cylinder is replaced in time, but it will not be known that the plastic film has been unwound until the next process finds that there is no plastic film in place. This makes the process interval from the completion of unwinding of the plastic film to...
