Description

Technical Field

[0001] This utility model relates to the field of pressure repressing technology, and in particular to a pressure repressing device for a composite membrane. Background Technology

[0002] A laminating machine, also known as a laminating unit, is a key piece of equipment used to laminate multiple layers of substrates into a single membrane through hot pressing, coating, or bonding processes. In the production of resin-based composite films, the laminating unit controls parameters such as temperature, pressure, and tension to achieve uniform bonding of each layer of material, directly affecting the flatness, bonding strength, and overall performance of the composite film.

[0003] This device typically consists of modules for unwinding, gluing, laminating, and rewinding.

[0004] However, existing lamination devices still have significant drawbacks in actual operation. Due to the susceptibility of each substrate layer to tension fluctuations, alignment deviations, and dimensional variations during unwinding, traction, and lamination, uneven offset or misalignment often occurs at the edges of the laminated film after lamination. This problem necessitates the additional transfer of the laminated film to a separate slitting device for edge trimming to eliminate offset and meet dimensional requirements. This process not only increases the complexity of material handling, equipment configuration, and manual operation but also significantly reduces overall production efficiency due to intermediate stops and secondary processing.

[0005] To address this, we propose a composite membrane repressurization device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a composite membrane repressurization device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a composite film repressing device, including a laminating machine, wherein two guide components are fixedly connected to one side of the top frame of the laminating machine, and the guide components are located between the laminating mechanism and the winding mechanism of the laminating machine;

[0008] The top of the composite machine is symmetrically fixedly connected to two fixed frames, and two splined shafts are provided between the two fixed frames. Both ends of the two splined shafts are fixedly connected to rotating shafts, and the rotating shafts pass through the fixed frames and are rotatably connected to the fixed frames. A synchronous opposite drive assembly is installed between the two rotating shafts on the same side.

[0009] Both splined shafts are slidably fitted with fittings on their outer surfaces, and upper and lower circular cutters are fixedly fitted onto the outer surfaces of two adjacent fittings, respectively.

[0010] A synchronous adjustment assembly is installed between the four aforementioned assemblies and the two fixed frames;

[0011] The top of the laminating machine is fixedly connected to a waste material winding assembly on one side of the winding mechanism.

[0012] Furthermore, the guiding assembly includes two bearing seats, which are fixedly connected to the top frame of the laminating machine. The inner rings of the bearings built into the two bearing seats are jointly fixedly connected to a guide roller, providing a stable, low-resistance steering and support point for the composite film.

[0013] Furthermore, the synchronous opposite drive assembly includes two meshing gears, and the two gears are respectively fixedly connected to adjacent rotating shafts. A single-axis motor is fixedly connected to one side of the outer surface of the fixed frame, and the drive end of the single-axis motor is fixedly connected to the adjacent gear. By driving the single-axis motor in conjunction with a pair of meshing gears, the rotation of the two rotating shafts is synchronized and in opposite directions.

[0014] Furthermore, the synchronization adjustment component includes a handwheel, which is located on one side of an adjacent fixed frame. One end of the handwheel is fixedly connected to a bidirectional screw, which passes through both fixed frames and is rotatably connected to them. The outer surface of the bidirectional screw is symmetrically threaded with two sliding blocks, which are rotatably fitted onto the outer surfaces of two adjacent assembly parts. The handwheel allows for convenient manual driving of the bidirectional screw.

[0015] Furthermore, the top of each of the fixing brackets is threaded with a hand-tightening bolt, and the bottom of the hand-tightening bolt abuts against the top of the bidirectional screw, which can be used to lock the bidirectional screw.

[0016] Furthermore, the waste winding assembly includes two support frames, which are symmetrically and fixedly connected to the top of the laminating machine. A dual-axis motor is fixedly connected to the top of both support frames. A winding roller is fixedly connected to each of the two drive ends of the dual-axis motor, and the winding roller is rotatably connected to the adjacent support frame, which can perform a winding operation on the cut-off film edge.

[0017] The beneficial effects of this utility model are:

[0018] In use, this invention achieves online synchronous slitting of the composite film after re-pressing by setting a splined shaft, a synchronous and opposite-direction drive assembly, and upper and lower circular knives that are equipped and supported between the composite mechanism and the winding mechanism, in conjunction with a synchronous adjustment assembly and a waste material winding assembly. This directly eliminates the defect of edge offset of the composite film in the prior art, saves the need for independent slitting equipment and secondary processing, and significantly improves production efficiency. Among them, the synchronous adjustment assembly can make the two sets of circular knives move synchronously, quickly adapting to the slitting requirements of composite films of different widths.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-5 As shown, a composite film repressing device is disclosed, including a laminating machine 1. Two guide components are fixedly connected to one side of the top frame of the laminating machine 1, and the guide components are located between the laminating mechanism and the winding mechanism of the laminating machine 1. The guide components include two bearing seats 15, and the bearing seats 15 are fixedly connected to the top frame of the laminating machine 1. The inner rings of the bearings built into the two bearing seats 15 are fixedly connected to a guide roller 7.

[0029] Two fixed brackets 5 are symmetrically fixedly connected to the top of the composite machine 1. Two splined shafts 10 are provided between the two fixed brackets 5. The two ends of the two splined shafts 10 are fixedly connected to the rotating shafts 18, which pass through the fixed brackets 5 and are rotatably connected to the fixed brackets 5. The rotating shafts 18 and the fixed brackets 5 are rotatably connected through existing bearing seats. The bearing seat body is fixed to the fixed bracket 5. The inner ring of the bearing built into the bearing seat is fixedly sleeved on the outer surface of the rotating shaft 18. A synchronous opposite drive assembly is installed between the two rotating shafts 18 on the same side. The synchronous opposite drive assembly includes two meshing gears 9, and the two gears 9 are fixedly connected to the adjacent rotating shafts 18 respectively. A single-axis motor 8 is fixedly connected to one side of the outer surface of the fixed bracket 5, and the drive end of the single-axis motor 8 is fixedly connected to the adjacent gear 9. The bottom of the single-axis motor 8 is matched with a mounting base. The mounting base is fixedly connected to the adjacent fixed bracket 5 by existing bolts, which facilitates the disassembly and assembly of the single-axis motor 8. The single-axis motor 8 is fixedly connected to the mounting shaft of the gear 9 through an existing coupling.

[0030] The outer surfaces of the two splined shafts 10 are slidably fitted with mounting sets 13. The outer surfaces of two adjacent mounting sets 13 are respectively fixedly fitted with upper circular cutter 12 and lower circular cutter 11. The upper circular cutter 12 and lower circular cutter 11 are fixed to the mounting sets 13 with existing screws, which is convenient for disassembly and assembly.

[0031] A synchronous adjustment assembly is installed between the four mounting brackets 13 and the two fixed brackets 5. The synchronous adjustment assembly includes a handwheel 16, which is located on one side of the adjacent fixed bracket 5. One end of the handwheel 16 is fixedly connected to a bidirectional screw 6, which passes through both fixed brackets 5 and is rotatably connected to them. The bidirectional screw 6 achieves rotatable connection with the fixed brackets 5 through existing bearing seats. The bearing seat body is fixed to the fixed bracket 5, and the inner ring of the bearing inside the bearing seat is fixedly sleeved on the outer surface of the bidirectional screw 6. The thread helix angle of the bidirectional screw 6 is smaller than the friction angle, giving the bidirectional screw 6 a self-locking capability and preventing vibration. The double-acting screw 6 is automatically displaced by movement or load. Two slides 14 are symmetrically threaded on the outer surface of the double-acting screw 6. The slides 14 are rotatably sleeved on the outer surfaces of two adjacent mounting sets 13. The slides 14 and the mounting sets 13 are also rotatably connected through existing bearing seats. The bearing seat body is fixed to the slides 14. The inner ring of the bearing inside the bearing seat is fixedly sleeved on the outer surface of the mounting set 13. The top of the single fixing bracket 5 is threaded with a hand-tightening bolt 17. The bottom of the hand-tightening bolt 17 abuts against the top of the double-acting screw 6. The top of the hand-tightening bolt 17 is provided with a knob for easy hand-tightening. The function of the hand-tightening bolt 17 is to lock the double-acting screw 6.

[0032] The top of the laminating machine 1 is fixedly connected to a waste material winding assembly on one side of the winding mechanism. The waste material winding assembly includes two support frames 4, which are symmetrically fixedly connected to the top of the laminating machine 1. The top of the two support frames 4 is fixedly connected to a dual-axis motor 3. The two drive ends of the dual-axis motor 3 are fixedly connected to winding rollers 2, and the winding rollers 2 are rotatably connected to the adjacent support frames 4. The winding rollers 2 and the support frames 4 are rotatably connected through existing bearing seats. The seat of the bearing seat is fixed to the support frame 4, and the inner ring of the bearing built into the bearing seat is fixedly sleeved on the outer surface of the winding rollers 2.

[0033] In this application, both the dual-axis motor 3 and the single-axis motor 8 are electrically connected to the controller used by the composite machine 1, which is beneficial for controlling the dual-axis motor 3 and the single-axis motor 8.

[0034] Working principle: Two film substrates are unwound by an external unwinding mechanism, and then laminated by the laminating mechanism of laminating machine 1. After being output from the laminating mechanism of laminating machine 1, the laminated film is first guided and tensioned by the guide roller 7 supported by the bearing seat 15 at the top.

[0035] Subsequently, the composite film enters the cutting area, the single-axis motor 8 runs, and the single-axis motor 8 drives one of the gears 9 to rotate. Through the two meshing gears 9, the two rotating shafts 18 connected to them rotate synchronously in opposite directions, thereby driving the two splined shafts 10 to rotate synchronously in opposite directions.

[0036] Since each spline shaft 10 has two slidably sleeved assembly pieces 13, when the two spline shafts 10 rotate, they can drive the two slidably sleeved assembly pieces 13 to rotate, thereby driving the upper circular cutter 12 and the lower circular cutter 11 to rotate, cutting the composite film and removing the film edge.

[0037] The cutting width is adjusted by rotating the handwheel 16. The handwheel 16 drives the bidirectional screw 6 to rotate, which in turn drives the two slides 14 on it to move in opposite directions. Since each slide 14 is rotatably sleeved on the two fittings 13 on the same side, it synchronously drives all fittings 13 and their upper and lower circular cutters 12 and 11 to move along the spline shaft 10. After adjustment, the hand-tightened bolt 17 can be tightened to fix the bidirectional screw 6.

[0038] The cut-off waste film edge is guided to the waste film winding assembly by the bottom guide roller 7. The dual-axis motor 3 drives the two winding rollers 2 to rotate simultaneously, winding the waste film edge on both sides onto the two winding rollers 2 respectively.

[0039] Finally, the trimmed composite film is also conveyed to the winding mechanism of the laminating machine 1 via the bottom guide roller 7 for finished product winding.
