Description

Technical Field

[0001] The utility model relates to the technical field of film production, and more specifically, to a winding device for composite films that prevents wrinkling. Background Art

[0002] A composite film is a polymer material composed of two or more layers of films made of different materials. After the composite film product is formed, it needs to be wound up for convenient packaging and transportation of the finished product. During the winding process, due to problems such as position deviation and uneven force, the film is prone to wrinkling, which affects the flatness of the film winding and the quality of the finished product.

[0003] In the prior art, for example, the utility model patent with the application number CN2202321797739.0 discloses an FH-type polyimide composite film winding device. The reset elastic force of the positioning spring drives the movable plate to move downward, and the movable plate drives the pressing roller to move downward to the surface of the composite film, thereby flattening the composite film. In this flattening method, the whole pressing roller contacts the composite film. As the composite film moves, the force at the wrinkled part is relatively large, and local stretching deformation is likely to occur.

[0004] Therefore, it is necessary to propose a winding device for composite films that prevents wrinkling to at least partially solve the problems existing in the prior art. Summary of the Utility Model

[0005] A series of simplified concepts are introduced in the summary of the utility model part, which will be further described in detail in the specific implementation part. The summary of the utility model part does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] To solve the above problems, the utility model discloses a winding device for composite films that prevents wrinkling, which includes:

[0007] A winding roller is arranged on one side of the machine table. The rotating shaft of the winding roller is connected to the output end of the first motor, and the end of the composite film is wound around the winding roller.

[0008] A flattening assembly is arranged in front of the winding roller. The flattening assembly includes a gantry and flattening rollers. The composite film passes through the inside of the gantry. The flattening rollers are rotatably connected inside the gantry, and a plurality of elastically arranged flattening plates are connected to the flattening rollers at intervals. The flattening plates abut against the upper surface of the composite film.

The height of the bottom end of the guiding roller is lower than the height of the top end of the winding roller, and the composite film contacts the bottom of the guiding roller.

[0011] Preferably, three lugs are evenly arranged on the outer wall of the flattening roller along the circumferential direction, and the flattening plate is rotatably connected to the lugs through a rotating shaft.

[0012] Preferably, a torsion spring is arranged at the connection between the rotating shaft and the lug.

[0013] Preferably, the flattening plate is set as an arc-shaped plate that bends towards the center of the flattening roller.

[0014] Preferably, a pressing plate is connected to the top of the gantry. The pressing plate is arranged above the flattening roller, and an arc-shaped surface is arranged at the bottom of the pressing plate. The flattening plate can be retracted into the gap between the pressing plate and the flattening roller.

[0015] Preferably, a slope is arranged on one side of the bottom of the pressing plate close to the winding roller.

[0016] Preferably, a plurality of groups of flattening plates are evenly arranged along the axial direction of the flattening roller.

[0018] Compared with the prior art, the present utility model at least includes the following beneficial effects:

[0019] The anti-wrinkle composite film winding device provided by the present utility model. During the movement of the composite film, it contacts the flattening plates on the flattening roller. When there are wrinkles on the composite film, the flattening plates flatten the wrinkles on the surface of the composite film, improving the flatness of the composite film; the flattening plates are in intermittent contact with the composite film. Compared with the way that the whole flattening roller contacts the composite film, it can better adjust the tension of the composite film and avoid excessive pulling and deformation of the composite film during the flattening process.

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings.

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Embodiment

[0028] The following will further describe the present invention in conjunction with the drawings.

[0029] As Figure 1 、 2 shown, the anti-wrinkle composite film winding device provided in this embodiment includes:

[0030] A winding roller 1, which is arranged on one side of the machine table 2. The rotating shaft of the winding roller 1 is connected to the output end of the first motor, and the end of the composite film 3 is wound around the winding roller 1;

[0031] A flattening assembly, which is arranged in front of the winding roller 1. The flattening assembly includes a gantry 4 and a flattening roller 5. The composite film 3 passes through the inside of the gantry 4; the flattening roller 5 is rotatably connected inside the gantry 4, and a plurality of elastically arranged flattening plates 6 are connected to the flattening roller 5 at intervals, and the flattening plates 6 abut against the upper surface of the composite film 3.

[0032] The working principle and beneficial effects of the present invention are:

[0033] The coiling device for preventing wrinkling of the composite film provided in this embodiment, when coiling the composite film 3, passes the composite film 3 through the center of the gantry 4 of the flattening assembly, and then winds it around the coiling roller 1 and fixes it; starts the first motor to drive the coiling roller 1 to rotate, drives the composite film 3 to pass through the gantry 4 in the horizontal direction, and the composite film 3 contacts the flattening plate 6 on the flattening roller 5 during the movement. When there are wrinkles on the composite film 3, the wrinkles are unfolded under the pressure of the flattening plate 6, thereby flattening the wrinkles on the surface of the composite film 3 and further improving the flatness of the composite film 3; the flattening plate 6 is in intermittent contact with the composite film 3. Compared with the way that the whole flattening roller 5 contacts the composite film 3, it can better adjust the tension of the composite film 3 and avoid excessive pulling and deformation of the composite film 3 during the flattening process.

[0034] Among them, the rotating shaft of the flattening roller 5 is rotatably connected to the front and rear walls of the gantry 4, one end of the rotating shaft of the flattening roller 5 is connected to the output end of the second motor, and the flattening roller 5 rotates counterclockwise.

[0035] The second motor drives the flattening roller 5 to rotate, so that there is a certain speed difference between the flattening roller 5 and the composite film 3, ensuring the smooth progress of the flattening process.

[0036] Among them, a guide roller 7 is connected to the top of the gantry 4. The number of guide rollers 7 is set to two and they are distributed on both sides of the flattening roller 5. The height of the bottommost part of the guide roller 7 is lower than the height of the topmost part of the coiling roller 1, and the composite film 3 contacts the bottom of the guide roller 7.

[0037] The guide roller 7 plays a guiding role for the composite film 3, enabling the composite film 3 to enter the gantry 4 in a horizontal state. The center of the composite film 3 and the center of the flattening roller 5 maintain a preset distance, ensuring effective contact between the flattening plate 6 and the composite film 3.

[0038] As Figure 1 、 2 shown, in one embodiment, three lugs 8 are evenly arranged on the outer wall of the flattening roller 5 along the circumferential direction, and the flattening plate 6 is rotatably connected to the lug 8 through a rotating shaft 9.

[0039] A coil spring is arranged at the connection between the rotating shaft 9 and the lug 8.

[0040] The flattening plate 6 is set as an arc-shaped plate that bends towards the center of the flattening roller 5.

[0041] A pressing plate 10 is connected to the top of the gantry 4. The pressing plate 10 is arranged above the flattening roller 5. The bottom of the pressing plate 10 is provided with an arc-shaped surface, and the flattening plate 6 can be retracted into the gap between the pressing plate 10 and the flattening roller 5.

[0042] A slope is arranged on one side of the bottom of the pressing plate 10 close to the coiling roller 1.

[0043] The working principle and beneficial effects of the above technical solutions are as follows:

[0044] When the smoothing assembly is in use, the second motor is started to drive the smoothing roller 5 to rotate in the counterclockwise direction, driving the smoothing plate 6 to rotate in the counterclockwise direction, and the two smoothing plates 6 located at the bottom are in an unfolded state, and the smoothing plate 6 is bent toward the center of the smoothing roller 5; as the smoothing roller 5 rotates, the protruding arc surface of the smoothing plate 5 contacts the wrinkles on the composite film 3 to smooth the wrinkles; when the smoothing plate 6 rotates to contact with the pressure plate 10, it is pressed by the pressure plate 10 and the smoothing plate 6 rotates toward the smoothing roller 5 and is retracted between the outer wall of the smoothing roller 5 and the pressure plate 10; during the retraction process, the rotating shaft 9 rotates and stores energy for the winding spring; when the smoothing plate 6 is separated from the pressure plate 10, the smoothing plate 6 is quickly unfolded and reset under the action of the winding spring. On the one hand, the smoothing plate 6 knocks on the composite film 3 to loosen the dust on the composite film 3; on the other hand, a certain pressure is applied to the wrinkled part to facilitate the smoothing of the wrinkles, thereby improving the anti-wrinkling ability of the composite film.

[0045] like Figure 1 , 3 As shown, in one embodiment, the smoothing roller 5 is evenly arranged with multiple smoothing plate groups along the axial direction, and each smoothing plate group includes three smoothing plates 6 evenly distributed along the circumferential direction; the smoothing rollers 5 are arranged in parallel as two, and the smoothing plates 6 on the two smoothing rollers 5 are arranged alternately.

[0046] The working principle and beneficial effects of the above technical solution are:

[0047] Multiple smoothing plate groups are arranged at intervals on the smoothing roller 5, which can avoid the problem of excessive pulling when smoothing wrinkles due to excessive contact area between the smoothing plate 6 and the composite film 3 in the width direction; by arranging two parallel smoothing rollers 5 and staggered smoothing plates 6, the gaps between adjacent smoothing plate groups can be supplemented to ensure the integrity of the smoothing range.

[0048] like Figure 1 As shown, in one embodiment, a cleaning nozzle 11 is provided on the door frame 4, and two cleaning nozzles 11 are obliquely arranged on both sides of the smoothing roller 5, and the cleaning nozzles 11 are connected to the air source equipment through pipelines.

[0049] The working principle and beneficial effects of the above technical solution are:

[0050] A cleaning nozzle 11 is arranged on the door frame 4, and an air flow is transported into the cleaning nozzle 11 through an air source device. The cleaning spray 11 is sprayed onto the composite film 3 to blow off dust and particulate matter on the composite film 3, thereby improving the cleanliness of the rolled product and preventing the dust and particulate matter from being damaged by the pressure of the smoothing plate 6 during the smoothing process.

[0052] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present utility model.
