Embodiment Construction
[0020] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0021] Such as Figure 1 to Figure 7 As shown, the film cutting and winding machine includes a workbench 1 and fixed plates 2 located on both sides of the workbench 1. Two pinch rollers 27 and a tension roller 29 are rotatably connected between the two fixed plates 2. The tension roller 29 is positioned above one end of the workbench 1, and the two hold-down rollers 27 abut against the workbench 1. There is an interval between the two hold-down rollers 27, and there is also a space between the two fixed plates 2. The cutting structure for cutting the film, the film cutting structure is located between two pinch rollers 27, the other end of the workbench 1 is located above one of the fixed plates 2, and there is a winding s...

The invention provides an unwinding structure of a film cutting winding machine, belongs to the technical field of machinery, and solves the technical problems such as that the conventional film cutting winding machine is low in efficiency. The film cutting winding machine comprises a working table and two fixing plates positioned on the two sides of the working table separately, wherein a tensioning roller wheel is rotatably connected between the two fixing plates; the tensioning roller wheel is positioned at the part above one end of the working table; the unwinding structure is connected toone end of the working table and comprises a square outer fixing frame and a square inner fixing frame; one side surface of the outer fixing frame is fixed with one end of the working table; an upperannular convex edge protruding inwards is arranged at the upper end of the outer fixing frame; a lower annular convex edge protruding outwards is arranged at the lower end of the inner fixing frame;the inner fixing frame can be inserted into the outer fixing frame and fixed with the outer fixing frame; and an unwinding roller wheel is rotatably connected with the interior of the inner fixing frame. The unwinding structure of the film cutting winding machine has the advantage that the unwinding roller wheel can be replaced efficiently.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to a film cutting and winding machine, in particular to an unwinding structure of the film cutting and winding machine. Background technique [0002] In the existing film production, the film is uniformly wound onto the roller first, and the length and width of the newly produced film are relatively large, but in reality, the width and length of the film have standards, so in order to meet the sales of the film, it is necessary to The film is re-cut and rewound so that the film is rewound onto the reel. Cutting and winding of films are currently less efficient. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose an unwinding structure of a film cutting and rewinding machine. The technical problem solved by the present invention is to realize the replacement of unwinding rollers eff...
