Description

Technical Field

[0001] This application relates to the field of film production equipment, and in particular to a film composite winding device. Background Technology

[0002] DMD composite film is a multilayer insulating material made of polyester fiber nonwoven fabric and polyester film bonded together with an adhesive. It has excellent electrical properties, mechanical strength and heat resistance, and is widely used in motors, transformers, electronic devices and other fields.

[0003] In the relevant technology, the production process of DMD composite film first involves coating the surface of polyester film with adhesive and curing the adhesive layer in an oven. Then, non-woven fabric and polyester film are laminated together using a pressing device. Finally, the produced DMD composite film is rolled up using a rolling device. The completed DMD roll is then manually unloaded and transported from the rolling device.

[0004] Regarding the aforementioned technologies, the inventors believe that since both polyester fiber nonwoven fabric and polyester film are insulating materials, the aforementioned winding device is prone to generating static electricity when winding DMD composite film, which may cause discharge sparks when the operator disassembles the film, thus posing a certain safety hazard. Utility Model Content

[0005] In order to improve the problem of static electricity generated when the film winding device is winding the film, this application provides a film composite winding device.

[0006] The film composite winding device provided in this application adopts the following technical solution:

[0007] A film lamination and winding device includes a pressing mechanism for laminating nonwoven fabric to the upper and lower surfaces of a polyester film, and a winding mechanism for winding the laminated film product. The pressing mechanism includes a mounting frame, a pressing assembly arranged on the mounting frame for pressing the nonwoven fabric to the surface of the polyester film, a first feeding roller assembly arranged on the upper side of the mounting frame for conveying the nonwoven fabric, and a second feeding roller assembly arranged on the lower side of the mounting frame for conveying the nonwoven fabric. The winding mechanism includes a winding frame, a drive roller rotatably arranged on the winding frame, a first support roller rotatably arranged on the winding frame and cooperating with the drive roller, and a drive motor for driving the drive roller to rotate. The winding mechanism is provided with a conductive component for reducing static electricity on the surface of the nonwoven fabric. The conductive component includes a grounding electrode and a grounding wire with one end connected to the grounding electrode and the other end in contact with the film product.

[0008] By adopting the above technical solution, when using the film lamination and winding device to laminate and wind the composite film, the drive roller rotates under the drive of the drive motor and carries the glued and cured polyester film to the pressing assembly. At the same time, the first feeding roller assembly located above the mounting frame carries the nonwoven fabric used for laminating the upper surface of the polyester film to the pressing assembly, and the second feeding roller assembly located below the mounting frame carries the nonwoven fabric used for laminating the lower surface of the polyester film to the pressing assembly. The pressing assembly presses the nonwoven fabric onto the upper and lower surfaces of the polyester film. The laminated film is then conveyed to the winding mechanism and wound up by the drive roller. During the winding process, the conductive component is used to conduct the static electricity on the surface of the nonwoven fabric to the ground, which helps to improve the problem of static electricity generated when the winding device winds up the film.

[0009] Optionally, the grounding wire includes an insulating section and a conductive section connected to the insulating section, the end of the insulating section is connected to the grounding electrode, and the conductive section is arranged in contact with the surface of the finished film.

[0010] By adopting the above technical solution, the grounding wire is equipped with an insulating section and a conductive section. The insulating section is connected to the grounding electrode, and the conductive section is attached to the surface of the finished film. This can effectively conduct static electricity on the finished film to the ground through the conductive section and the grounding electrode. At the same time, the insulating section can reduce the risk of personnel accidentally touching the conductive part, which helps to improve the safety of the grounding wire.

[0011] Optionally, a counterweight is provided at the end of the conductive segment, and the counterweight has a fixing pull ring for connecting the conductive segment.

[0012] By adopting the above technical solution, the setting of counterweight and fixing ring can make the conductive section of the grounding wire stably attached to the surface of the finished film, thereby more effectively reducing the static electricity on the surface of the nonwoven fabric.

[0013] Optionally, the roll holder is provided with a mounting link arranged parallel to the take-up roller on the side near the pressing mechanism. The mounting link is detachably mounted with a mounting ring that cooperates with the counterweight to limit the grounding wire. The mounting ring has a mounting portion for connecting one end of the insulating section near the conductive section.

[0014] By adopting the above technical solution, the grounding wire is limited and connected by the mounting ring on the mounting rod and cooperates with the counterweight to ensure that the grounding wire can always be attached to the surface of the finished film when the drive roller rotates. This helps to more stably reduce the static electricity on the surface of the nonwoven fabric. In addition, the mounting ring is detachable, which facilitates the later maintenance and replacement of the grounding wire.

[0015] Optionally, the roll holder has mounting seats for accommodating both ends of the drive roller, the ends of the drive roller are provided with spring clips, and the mounting seats have mounting grooves that cooperate with the spring clips.

[0016] By adopting the above technical solution, the spring clip and the mounting slot of the mounting base cooperate to achieve detachable installation on the coil rack, which facilitates the replacement and maintenance of the drive roller.

[0017] Optionally, the number of drive rollers is two and they are arranged in parallel on the coil frame, and the coil frame is provided with two drive motors that drive one of the drive rollers to rotate.

[0018] By adopting the above technical solution, the two parallel drive rollers are driven to rotate by two drive motors respectively, which can improve the efficiency and stability of the roll mechanism in winding composite products.

[0019] Optionally, the pressing assembly includes a steel roller rotatably mounted in the middle of the mounting frame, a servo motor driving the steel roller to rotate, a pressure roller slidably arranged in the mounting frame and cooperating with the steel roller to press the material strip together, and a drive cylinder driving the pressure roller to slide.

[0020] By adopting the above technical solution, the specific structure of the pressing component is disclosed. By using a servo motor to drive the steel roller to rotate and a drive cylinder to drive the pressure roller to slide and cooperate with the steel roller, stable pressing of the material strip can be achieved, improving the bonding tightness between the nonwoven fabric and the polyester film during the lamination process, thereby ensuring the lamination quality of the finished film.

[0021] Optionally, the first feed roller assembly includes a first tension roller rotatably mounted on the mounting frame for arranging the nonwoven fabric roll on the upper surface, and a plurality of first driven rollers for conveying the nonwoven fabric roll to the pressing assembly.

[0022] By adopting the above technical solution, the specific structure of the first feeding roller assembly is disclosed. The first tensioning roller and multiple first driven rollers cooperate to convey and tension the nonwoven fabric roll to be laminated onto the upper surface of the polyester film, ensuring the stability and tension of the nonwoven fabric conveying, which is beneficial to the subsequent lamination process.

[0023] Optionally, the second feed roller assembly includes a second tension roller rotatably mounted on the mounting frame for arranging the nonwoven fabric roll on the lower surface, and a plurality of second driven rollers for conveying the nonwoven fabric roll to the pressing assembly.

[0024] By adopting the above technical solution, the specific structure of the second feeding roller assembly is disclosed. The second tensioning roller and multiple second driven rollers cooperate to convey and tension the nonwoven fabric roll to be laminated to the lower surface of the polyester film, ensuring the stability and tension of the nonwoven fabric conveying, which is beneficial to the subsequent lamination process.

[0025] Optionally, the output end of the pressing mechanism is provided with a second support roller, and a quality inspection component is provided on the side of the second support roller near the pressing assembly; the quality inspection component includes a first lighting lamp and a second lighting lamp arranged on the mounting frame and arranged opposite to each other, the horizontal height of the first lighting lamp is higher than the horizontal height of the second support roller, and the horizontal height of the second lighting lamp is lower than the horizontal height of the second support roller.

[0026] By adopting the above technical solution, when the composite film passes through the second support roller, it can be illuminated by a first and a second light lamp arranged opposite each other and at different heights, so as to illuminate the film from opposite angles and make it easier to detect the film composite quality more clearly.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. A film lamination and winding device, comprising a pressing mechanism and a winding mechanism; when using the film lamination and winding device to laminate and wind composite films, under the drive of a drive motor, a drive roller rotates and drives the pre-coated and cured polyester film to the pressing assembly, whereby the pressing assembly presses the nonwoven fabric onto the upper and lower surfaces of the polyester film. The laminated film is then conveyed to the winding mechanism and wound up by the drive roller; during the winding process, a conductive component is used to conduct static electricity from the surface of the nonwoven fabric to the ground, which helps to improve the problem of static electricity generated when the winding device winds up the film;

[0029] 2. By setting up insulating and conductive sections, with the insulating section connected to the grounding electrode and the conductive section attached to the surface of the finished film, static electricity on the finished film can be effectively conducted to the ground through the conductive section and the grounding electrode. At the same time, the insulating section can reduce the risk of personnel accidentally touching the conductive part, which helps to improve the safety of the grounding wire.

[0030] 3. The grounding wire is limited and connected by the mounting ring and cooperates with the counterweight to ensure that the grounding wire can always be in contact with the surface of the finished film when the drive roller rotates. This helps to reduce static electricity on the surface of the nonwoven fabric more stably. The mounting ring is also detachable, which facilitates the later maintenance and replacement of the grounding wire. Attached Figure Description
