Description

Technical Field

[0001] This utility model belongs to the technical field of stretch film production equipment, specifically a slitting device for the production of conductive stretch film. Background Technology

[0002] Conductive film is a thin film material with conductive properties. The substrate is mostly polyester (PET) film, which has insulation, heat resistance and high elasticity. Film layers with a thickness of less than 0.25mm are mainly used for thin-film keyboard touch panels, while board layers with a thickness of more than 0.25mm are used as structural backing plates. This material is widely used in antistatic films, thin-film keyboard circuits, touch screen sensors and solar cell electrodes. Conductive wrapping film needs to be cut by a slitting device during processing.

[0003] In a Chinese patent for a slitting device for producing conductive stretch film (authorization number: CN220975987U), the device includes: a worktable, with support legs fixedly connected to the lower part of the worktable; a vertical plate fixedly mounted on the worktable; an installation groove on one side of the vertical plate; a detachable unwinding roller slidably connected to the installation groove; a roll of conductive stretch film sleeved on the detachable unwinding roller; a first motor fixedly mounted on one side of the vertical plate; and an adjustable tensioning device between the vertical plates. The first motor passes through the vertical plate and is connected to the adjustable tensioning device. This device unwinds the conductive stretch film... After the roll is finished, the detachable unwind roller can be quickly disassembled, making it easy to add new rolls of conductive wrapping film. The adjustable tensioning device can adjust the distance between each tensioning roller to prevent poor tension from causing deviations during cutting and affecting the quality of the finished product. However, this device cannot automatically adjust according to the tension of the conductive wrapping film in a timely manner, thus affecting the timely tension adjustment of the conductive wrapping film during the cutting and conveying process, which affects product quality. In addition, the static electricity generated during the cutting process easily attracts dust, which not only contaminates the film material but also affects its conductivity. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a slitting device for producing conductive winding film, comprising a slitting table. From left to right, an unwinding machine, an automatic tension adjustment mechanism, a slitting knife assembly, and a winding machine are sequentially mounted on the upper surface of the slitting table. The automatic tension adjustment mechanism includes a concave plate frame fixed to the upper surface of the slitting table. A locking motor is fixedly connected to the front side wall of the concave plate frame. The main shaft end of the locking motor extends through to the inner side of the concave plate frame and is fixedly connected to a rotating rod. Both ends of the rotating rod are fixedly connected to discs. Each disc... The outer side walls are hinged with three equally spaced tie rods. The inner walls of the opposite sides of the concave plate frame are each provided with three equally spaced sliding grooves centered on a disc. A slider is slidably connected in each groove. Each tie rod is hinged to a slider. Each slider is fixedly connected to an L-shaped plate. A pressure sensor is fixedly connected to the inner wall of the L-shaped plate. A rotating seat is fixedly connected to the pressure sensor. Three tensioning rollers are rotatably connected between the three sets of rotating seats. An anti-static mechanism is fixedly connected to the upper end of the side of the concave plate frame closest to the unwinding machine.

[0005] As a further embodiment of this utility model: the antistatic mechanism includes an ion generator and an ion air bar connected to the ion generator. The ion generator is installed on the front side wall of the concave plate frame, and the ion air bar is installed on the upper end of the concave plate frame near the unwinding machine.

[0006] As a further embodiment of this utility model, a first guide roller is fixedly connected to the slitting table located between the unwinding machine and the automatic tensioning adjustment mechanism.

[0007] As a further embodiment of this utility model, a second guide roller is fixedly connected to the slitting table located between the slitting blade assembly and the winding machine.

[0008] As a further embodiment of this utility model: the inner wall of the cutting table on the side away from the locking motor is rotatably connected to one end of the rotating rod through a bearing seat.

[0009] As a further embodiment of this utility model: a control panel is fixedly connected to the front side wall of the slitting table, and the control panel is electrically connected to the winding machine, the locking motor, the pressure sensor and the anti-static mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting an automatic tension adjustment mechanism, presets the tension pressure of the conductive wrapping film. The pressure sensor can monitor the tension pressure of the tension roller on the conductive wrapping film. When the tension pressure is greater than the preset value, the locking motor is activated, driving the rotating rod to rotate, which in turn drives the two discs to rotate synchronously clockwise. At this time, the three sets of pull rods can be pulled to swing simultaneously, causing the slider to slide in the groove and move in a similar direction, thereby driving the three tension rollers to move in similar directions and shorten the distance, thus reducing the tension pressure on the conductive wrapping film. Conversely, similarly, the locking motor is activated to reverse the operation, which can increase the tension pressure on the conductive wrapping film. This realizes the automatic adjustment of the tension pressure of the tension roller on the conductive wrapping film, with a more timely response and ensuring product processing quality.

[0011] 2. This utility model, by setting an anti-static mechanism, continuously generates ion wind with the ion wind bar to eliminate static electricity on the conductive winding film and prevent dust adsorption. Attached Figure Description

[0014] Please see Figures 1-4This embodiment provides a slitting device for producing conductive wrapping film, which includes a slitting table 1. From left to right, an unwinding machine 2, an automatic tension adjustment mechanism, a slitting knife assembly 3, and a winding machine 5 are sequentially mounted on the upper surface of the slitting table 1. The automatic tension adjustment mechanism includes a concave plate frame 6 fixed to the upper surface of the slitting table 1. A locking motor 7 is fixedly connected to the front side wall of the concave plate frame 6. The main shaft end of the locking motor 7 extends through to the inner side of the concave plate frame 6 and is fixedly connected to a rotating rod 8. Both ends of the rotating rod 8 are fixedly connected to discs 9. Three equally spaced rings are hinged to the outer side wall of each disc 9. Around the tie rod 10, three equally spaced grooves 11 are formed on the inner walls of the opposite sides of the concave plate frame 6, with the disc 9 as the center. A slider 12 is slidably connected to each groove 11. Each tie rod 10 is hinged to one slider 12. Each slider 12 is fixedly connected to an L-shaped plate 14. A pressure sensor 15 is fixedly connected to the inner wall of the L-shaped plate 14. A rotating seat 16 is fixedly connected to the pressure sensor 15. Three tension rollers 17 are rotatably connected between the three sets of rotating seats 16. When the conductive winding film roll needs automatic tension adjustment during slitting... First, the tension pressure of the conductive wrapping film is preset. The pressure sensor 15 monitors the tension pressure of the tension roller 17 on the conductive wrapping film. When the tension pressure is greater than the preset value, the locking motor 7 is activated, driving the rotating rod 8 to rotate, which in turn drives the two discs 9 to rotate synchronously clockwise. At this time, the three sets of pull rods 10 can be pulled to swing simultaneously, causing the slider 12 to slide in the slide groove 11 and move in a similar direction, thereby driving the three tension rollers 17 to move in similar directions and shorten the distance, thus reducing the tension pressure on the conductive wrapping film. Conversely, similarly, the locking motor 7 is activated to reverse the operation, which can increase the tension pressure on the conductive wrapping film. The high tension pressure of the conductive wrapping film allows for automatic adjustment of the tension pressure of the tension roller 17, resulting in a more timely response and ensuring product processing quality. The upper end of the concave plate frame 6, near the unwinding machine 2, is fixedly connected to an anti-static mechanism. When the conductive wrapping film roll is cut, the conductive wrapping film roll is mounted on the unwinding machine 2, with one end passing over the upper side of the first guide roller 4, then passing through the automatic tension adjustment mechanism, and then being cut by the slitting knife group 3. After that, it passes over the upper side of the second guide roller 20, and finally the winding machine 5 winds up the cut conductive wrapping film.

[0015] like Figure 2 As shown: The antistatic mechanism includes an ion generator 18 and an ion air bar 19 connected to the ion generator 18. The ion generator 18 is installed on the front side wall of the concave plate frame 6, and the ion air bar 19 is installed on the upper end of the side of the concave plate frame 6 near the unwinding machine 2. The ion air bar 19 continuously generates ion air to eliminate static electricity on the conductive winding film and prevent dust from adsorbing.

[0016] like Figure 1 As shown: A first guide roller 4 is fixedly connected to the slitting table 1 located between the unwinding machine 2 and the automatic tension adjustment mechanism, which can guide the conductive wrapping film during slitting and conveying.

[0017] like Figure 1 As shown: A second guide roller 20 is fixedly connected to the slitting table 1 located between the slitting knife group 3 and the winding machine 5, which can guide the conductive wrapping film during slitting and conveying.

[0018] like Figure 2 As shown: The inner wall of the cutting table 1 on the side away from the locking motor 7 is rotatably connected to one end of the rotating rod 8 through a bearing seat, making the rotation of the rotating rod 8 more stable.

[0019] like Figure 1 As shown: The front side wall of the slitting table 1 is fixedly connected to the control panel 13. The control panel 13 is electrically connected to the winding machine 5, the locking motor 7, the pressure sensor 15 and the anti-static mechanism. It is easy to operate and has an external power supply. The circuit involved is existing technology and can be fully implemented by those skilled in the art, so there is no need to elaborate.

[0020] Working principle: When the conductive wrapping film roll needs automatic tension adjustment during slitting, the tension pressure of the conductive wrapping film is first preset. The pressure sensor 15 can monitor the tension pressure of the tension roller 17 on the conductive wrapping film. When the tension pressure is greater than the preset value, the locking motor 7 is started, driving the rotating rod 8 to rotate, which in turn drives the two discs 9 to rotate clockwise synchronously. At this time, the three sets of pull rods 10 can be pulled to swing simultaneously, causing the slider 12 to slide in the slide groove 11 and move in a similar direction, thereby driving the three tension rollers 17 to move in similar directions and shorten the distance, thus reducing the tension pressure on the conductive wrapping film. Conversely, the locking motor 7 is started to work in reverse, which can increase the tension pressure on the conductive wrapping film. This can realize the automatic adjustment of the tension pressure of the tension roller 17 on the conductive wrapping film, with a more timely response and ensuring product processing quality. At the same time, the ion wind bar 19 continuously generates ion wind to eliminate static electricity on the conductive wrapping film and prevent dust adsorption.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
