Description

Technical Field

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

[0002] In the composite film processing flow, it is often necessary to cut the continuously wound composite film into segments of a specific length.

[0003] Currently, mechanical cutting equipment is commonly used in the industry to complete this process. The working method is usually as follows: the film material is fed intermittently under the drive of the conveying mechanism. When the preset length is reached, the drive device (such as a cylinder) drives the cutter to press down and cooperate with the fixed die at the bottom to complete the cutting.

[0004] However, existing cutting equipment of this type has significant shortcomings in the film collection stage. Before cutting, the ends of the composite membrane mainly rely on pushing force and their own weight to fall onto the support frame below, so that the cut film can fall onto the support frame under the action of gravity. When the cut film length is short, the discharge process is relatively stable and can be stacked relatively neatly; however, when the cut film length is large (e.g., exceeding one meter), the film is very prone to swaying, drifting, or forward curling during the discharge process due to its own flexibility. This problem is particularly serious for some composite membranes that are inherently soft, often resulting in long film sheets being scattered messily on the support frame, forming a chaotic state of crisscrossing and folding. This not only affects the neatness of collection, but also often requires stopping the machine for manual sorting, increasing the labor intensity of operators, affecting production efficiency, and may cause wrinkles or contamination of the membrane material during the sorting process.

[0005] Therefore, we propose a composite film cutting device. Utility Model Content

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

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a composite film cutting device, including a film cutting machine and a support frame disposed on the discharge side of the film cutting machine. The film cutting machine is symmetrically and fixedly connected to two rodless cylinders on the outer wall of one side of the support frame, and the bottom of the movable ends of the two rodless cylinders are fixedly connected to a movable rod.

[0008] The movable rod is equipped with a double-cylinder telescopic assembly. The movable end of the double-cylinder telescopic assembly is fixedly connected to an adsorption plate on one side of the film cutting machine. Several straight tubes are uniformly fixed and interconnected on the outer surface of the adsorption plate on one side of the double-cylinder telescopic assembly. One end of the several straight tubes is fixedly connected to a cross seat.

[0009] The inner surface of the cross seat is evenly provided with several chambers, and the bottom of each of the chambers is provided with a flow channel, which is interconnected with the straight pipe.

[0010] Each of the aforementioned chambers is equipped with a magnetic piston assembly.

[0011] Furthermore, the film cutting machine is fixedly connected to a support frame on one side of the outer wall of the carrier frame, and the end of the rodless cylinder away from the film cutting machine is fixedly connected to the support frame, and the movable rod is slidably connected to the bottom of the support frame. The support frame provides a stable mounting and movement reference for the rodless cylinder and the movable rod.

[0012] Furthermore, the dual-cylinder telescopic assembly includes two telescopic cylinders, which are symmetrically and fixedly connected to the top of the movable rod. The piston rods of the two telescopic cylinders are both set through the movable rod and are jointly and fixedly connected to a plate. The adsorption plate and the cross seat are respectively fixedly connected to both sides of the plate, and the plate is partially covered and fixedly connected to the top of several adjacent straight tubes. The synchronous drive of the dual cylinders ensures the stability and levelness of the adsorption plate during the lifting process.

[0013] Furthermore, the bottom of the adsorption plate is evenly provided with multiple suction nozzles, and the suction nozzles are interconnected with adjacent straight tubes. The evenly distributed multiple suction nozzles can provide a uniform adsorption force to the end of the membrane.

[0014] Furthermore, each of the aforementioned chambers has an air hole extending to the top of the cross seat. The air hole allows the chamber above the piston plate to communicate with the atmosphere, ensuring that the air pressure is balanced and the piston moves smoothly and without obstruction when moving up and down.

[0015] Furthermore, several of the magnetic piston assemblies include an annular electromagnet, which is fixedly connected to the inner top of the chamber. A spring is sleeved on the outer surface of the annular electromagnet, and the spring is fixedly connected to the inner top of the chamber. The cooperation between the annular electromagnet and the spring constitutes a fast-response linear drive unit.

[0016] Furthermore, an iron base is fixedly connected to the bottom of the spring, and a piston plate is fixedly connected to the bottom of the iron base. The piston plate slides in a sealed fit with the inner wall of the cavity, and the iron base, as the magnetic force application point, ensures the effectiveness of the drive.

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

[0018] In use, this invention uses a rodless cylinder, a movable rod, and a double-cylinder telescopic assembly to drive the adsorption plate to move to and adsorb the end of the film before cutting. Combined with the gas force generated by the inner cavity of the cross seat and the magnetic piston assembly, the cut film (especially long films) can be smoothly detached and fall onto the support frame in a controlled manner. This effectively solves the problem of film drifting and curling during discharge, resulting in messy stacking. It achieves neat and automatic collection, reduces manual handling, and improves production efficiency. Attached Figure Description

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.

[0027] like Figures 1-4As shown, a composite film cutting device is disclosed, including a film cutting machine 1 and a support frame 4 disposed on the discharge side of the film cutting machine 1. The film cutting machine 1 is the main body of the device, and its function is to complete the fixed-length conveying and final cutting of the composite film. The support frame 4 is used to receive the cut film sheets. Two rodless cylinders 3 are symmetrically fixedly connected to the outer wall of the support frame 4 on one side of the film cutting machine 1. The bottom of the movable end of the two rodless cylinders 3 is fixedly connected to a movable rod 8. A support frame 2 is fixedly connected to the outer wall of the support frame 4 on one side of the film cutting machine 1. The end of the rodless cylinder 3 away from the film cutting machine 1 is fixedly connected to the support frame 2, and the movable rod 8 is slidably connected to the bottom of the support frame 2.

[0028] The movable rod 8 is equipped with a double-cylinder telescopic assembly. The movable end of the double-cylinder telescopic assembly is located on one side of the film cutting machine 1 and is fixedly connected to an adsorption plate 13. Several straight tubes 9 are uniformly fixed and interconnected on the outer surface of the adsorption plate 13 on one side of the double-cylinder telescopic assembly. One end of the several straight tubes 9 is fixedly connected to a cross seat 6. The double-cylinder telescopic assembly includes two telescopic cylinders 5, and the two telescopic cylinders 5 are symmetrically fixedly connected to the top of the movable rod 8. The piston rods of the two telescopic cylinders 5 are both set through the movable rod 8 and are fixedly connected to a plate 10. The adsorption plate 13 and the cross seat 6 are fixedly connected to both sides of the plate 10, and the plate 10 is partially covered and fixedly connected to the top of the adjacent several straight tubes 9.

[0029] The inner surface of the horizontal seat 6 is evenly provided with several chambers 15, and the bottom of each chamber 15 is provided with a flow channel 18, which is connected to the straight pipe 9. The bottom of the adsorption plate 13 is evenly provided with several suction nozzles 14, which are connected to the adjacent straight pipe 9. The top of each chamber 15 is provided with an air hole 7 that extends to the top of the horizontal seat 6.

[0030] Several chambers 15 are equipped with magnetic piston assemblies, each including an annular electromagnet 11, which is fixedly connected to the inner top of the chamber 15. A spring 12 is fitted on the outer surface of the annular electromagnet 11, and the spring 12 is fixedly connected to the inner top of the chamber 15. An iron base 16 is fixedly connected to the bottom of the spring 12, and a piston plate 17 is fixedly connected to the bottom of the iron base 16. The piston plate 17 slides in a sealed fit with the inner wall of the chamber 15. The spring 12 is made of stainless steel. The surface of the iron base 16 is treated with anti-corrosion to ensure service life. Two sealing rings are fixedly fitted on the outer surface of the piston plate 17, and the sealing rings fit with the inner wall of the chamber 15 to form a seal between the piston plate 17 and the inner wall of the chamber 15.

[0031] The rodless cylinder 3, the telescopic cylinder 5, and the annular electromagnet 11 are all electrically connected to the controller used by the film cutting machine 1, which facilitates the control of the overall operation.

[0032] Working principle: When the composite film is about to be fed into the film cutting machine 1, the part extending near the cutter is activated. At this time, two rodless cylinders 3 operate. The rodless cylinders 3 drive the double-cylinder telescopic assembly, the adsorption plate 13, and the cross seat 6 to move to one side of the film cutting machine 1 via the movable rod 8, so that the adsorption plate 13 passes through the two cutters and enters the film cutting machine 1. Subsequently, the two telescopic cylinders 5 are activated, and their piston rods extend downward, pushing the fixed plate 10, the adsorption plate 13, and the cross seat 6 to descend as a whole, so that the suction nozzles 14 at the bottom of the adsorption plate 13 come into contact with the film surface. After the adsorption plate 13 is in place, the magnetic piston assembly in each chamber 15 starts to work. The annular electromagnet 11 is energized, generating a magnetic force that attracts the iron seat 16 downward. The magnetic force overcomes the elastic force of the spring 12, driving the iron seat 16 and the piston plate 17 fixed thereto to slide upward in the chamber 15. The upward movement of the piston plate 17 creates a negative pressure in the space of the chamber 15 below the piston plate 17. This negative pressure is transmitted to the suction nozzle 14 of the adsorption plate 13 through the flow channel 18 and the straight pipe 9, thereby firmly adsorbing the protruding part of the composite membrane at the bottom of the adsorption plate 13.

[0033] Subsequently, the conveying mechanism of the film cutting machine 1 and the rodless cylinder 3 operate synchronously. The conveying mechanism feeds the composite film until it reaches the set length for cutting. At the same time, the rodless cylinder 3 drives the end of the composite film to move synchronously above the support frame 4 through various components.

[0034] Next, the membrane cutting machine 1 cuts the composite membrane, while the annular electromagnet 11 is de-energized, the iron seat 16 loses its magnetic attraction and moves downward under the action of the spring 12, pushing the piston plate 17 downward. A micro-gas impact force is formed in the space of the chamber 15 below the piston plate 17. This impact force is transmitted to the suction nozzle 14 of the adsorption plate 13 through the flow channel 18 and the straight pipe 9, which helps to push the end of the composite membrane away from the adsorption plate 13. After the composite membrane is cut, it will fall smoothly above the carrier frame 4 at a predetermined position under the action of gravity.

[0035] Subsequently, the dual-cylinder telescopic assembly resets and repeats the above cutting action, so that the cut diaphragm is stacked relatively flat on the support frame 4.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
