Description

Technical Field

[0001] This utility model relates to a metallized film slitting machine, specifically a metallized film slitting machine with an electrostatic elimination device, belonging to the field of metallized film slitting technology. Background Technology

[0002] During the slitting process of metallized films, high-speed friction and separation occur between the film and various rollers, easily generating and accumulating static charges. These static charges attract dust and impurities from the air, contaminating the film surface, leading to decreased slitting quality, uneven edges, and severely affecting the yield and performance of subsequent processing.

[0003] Chinese patent CN106219302B discloses a metallized film slitting machine with an electrostatic elimination device. This machine utilizes an electrostatic elimination roller to eliminate static electricity on the insulating layer of the metallized film strip; it also eliminates static electricity on the conductive layer of the metallized film strip by ensuring the film strip adheres tightly to the conductive layer; and a magnetic roller ensures the film strip remains firmly attached to the conductive layer, preventing it from being thrown off by the advancing metallized film strip. The electrostatic elimination device in this metallized film slitting machine has a simple structure, low equipment cost, and effectively eliminates static electricity on the metallized film strip without damaging the conductive layer, ensuring the quality of the slitting product. It has good implementation results and high application value.

[0004] However, the static elimination methods used are relatively limited. Metallized films have two different surfaces, one metallized and one non-metallized. A single static elimination method cannot efficiently and thoroughly treat both sides simultaneously, resulting in incomplete static elimination. Furthermore, traditional slitting machines have a relatively dispersed overall structure, requiring individual inspection during maintenance. Changing slitting specifications or performing maintenance is cumbersome, involves long downtime, and lacks flexibility and adaptability, failing to meet the demands of efficient and diversified production. Therefore, this application is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a metallized film slitting machine with an electrostatic elimination device to solve the above problems. It adopts a detachable integrated slitting component that integrates slitting and electrostatic elimination, making it easy to replace and maintain quickly. At the same time, it uses electrostatic bars and electrostatic elimination rollers to eliminate static electricity on both sides of the film, effectively preventing dust adsorption and improving product cleanliness and quality.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a metallized film slitting machine with an electrostatic elimination device, comprising a control base and a mounting base, wherein an unwinding roller, a rewinding roller, a guide roller one and a guide roller two are provided between the control base and the mounting base, and an integrated slitting assembly capable of eliminating electrostatic charge on both sides of the film is detachably installed between the control base and the mounting base.

[0007] Preferably, the integrated slitting assembly includes a main support and a slitting blade installed between the control base and the mounting base. The slitting blade is mounted on the main support via a blade holder. In actual use, the main support serves as the basic carrier and has an overall detachable structure, allowing for quick installation and removal from the control base and the mounting base. This makes maintenance and replacement relatively quick, and the slitting blade enables basic slitting functions.

[0008] Preferably, the main support consists of two mounting plates that are detachably fixed to the control base and the mounting base, respectively. Each mounting plate is connected to a fixing plate via a connecting rod, and a fixing link is provided between the two fixing plates. The two mounting plates are securely connected to the control base and the mounting base, respectively, to ensure the overall stability of the main support. The connecting rod connects the mounting plates and the fixing plates, and the fixing plates are connected to each other via the fixing link to form an integral frame structure. This structure not only enhances the strength of the main support but also makes the connection between the various components tighter and more reliable. In actual slitting operations, it can ensure the stable operation of the slitting blade and improve the slitting accuracy and quality.

[0009] Preferably, a tension detection roller, a guide roller three, an anti-static bar, a lifting roller, and an anti-static eliminator roller are installed between the two fixed plates. After the film to be cut is wound around the guide roller two, it sequentially passes through the tension detection roller, the guide roller three, the lifting roller, and the anti-static eliminator roller before entering the take-up roller. The tension detection roller can detect the tension of the film in real time and feed the detection signal back to the control host on the control base so as to control the speed of the unwinding roller and the take-up roller in a timely manner to adjust the tension and ensure that the tension of the film is stable during the cutting process, avoiding cutting quality problems due to uneven tension. The guide roller three guides the direction of film movement, ensuring that the film enters the subsequent rollers accurately along the predetermined path.

[0010] Preferably, an electrostatic bar is also installed between the two fixed plates. The electrostatic bar is located between the two guide rollers. The electrostatic bar can effectively eliminate the static electricity generated on the non-metallic surface of the film during operation, prevent static electricity from causing adverse effects such as dust adsorption on the film, ensure the cleanliness of the film, ensure that the film is completely free of static electricity before entering the winding roller, improve the winding quality, and make the wound film roll more neat and compact.

[0011] Preferably, the fixed plate has a control groove, and a sliding plate is provided in the control groove. The top end of the sliding plate is connected to the end of the lifting roller through a guide rod. The guide rod is rotatably connected to the end of the lifting roller. By controlling the sliding plate to slide up and down in the control groove, the guide rod can be driven to move up and down accordingly. Since the guide rod is rotatably connected to the end of the lifting roller, the up and down adjustment of the lifting roller can be realized.

[0012] Preferably, a servo motor is embedded in the control slot, and an eccentric disk is connected to the output shaft of the servo motor. After the servo motor is started, its output shaft drives the eccentric disk to rotate. The special shape design of the eccentric disk causes it to generate regular eccentric motion during rotation. This eccentric motion acts on the slider, which pushes the slider to slide up and down in the control slot. Since the slider is connected to the end of the lifting roller through the guide rod, and the guide rod is rotatably connected to the end of the lifting roller, the up and down sliding of the slider will drive the guide rod to move up and down accordingly, thereby realizing the precise up and down adjustment of the lifting roller.

[0013] Preferably, one end of the static eliminator roller is grounded via a grounding wire. The static eliminator roller can quickly conduct static electricity to the grounding wire through its special conductive material, and then the grounding wire conducts the static electricity into the ground, thereby effectively eliminating static electricity on the film surface.

[0014] Preferably, a control host is installed on the control base. The control host is electrically connected to each electrical component. The control host can receive instructions input by the operator and precisely control each electrical component according to a preset program. It can control the start, stop, and speed adjustment of the servo motor, thereby precisely controlling the lifting speed and position of the lifting roller to meet the slitting requirements of metallized films of different specifications.

[0015] The beneficial effects of this utility model are: 1. This utility model, through an integrated slitting component, combines the ion wind generated by the electrostatic bar with the physical grounding of the electrostatic elimination roller, to simultaneously and efficiently eliminate static electricity on both the non-metallic and metallic surfaces of the film. This effectively avoids the adsorption of dust and impurities due to static electricity during the slitting process, thereby ensuring the cleanliness of the film slitting, the neatness of the roll, and its subsequent performance.

[0016] 2. This utility model integrates multiple functional units such as slitting blade, tension detection, guiding, and static elimination into a single, quickly detachable main support, forming a modular slitting assembly. This design not only ensures the stability and slitting accuracy of the equipment but also greatly facilitates the replacement, inspection, and daily maintenance of functional components according to production needs, thereby enhancing the flexibility and practicality of the equipment.

[0017] 3. This utility model uses a servo motor to drive an eccentric disk to control the lifting and lowering of the lifting roller, achieving precise stepless adjustment. When the film tension is too high, this mechanical structure can provide buffering through the offset of the eccentric disk to avoid film tearing or breakage. Compared with the traditional spring structure, the response is more reliable, thereby enhancing the equipment's adaptability to different slitting conditions and operational safety.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-7 As shown, a metallized film slitting machine with an electrostatic elimination device includes a control base 1 and a mounting base 2. An unwinding roller 3, a winding roller 4, a guide roller 5, and a guide roller 6 are arranged between the control base 1 and the mounting base 2. An integrated slitting assembly 7 capable of eliminating electrostatic discharge on both sides of the film is detachably installed between the control base 1 and the mounting base 2.

[0022] In practical use, the film to be slit is released from the unwinding roller 3 and then sequentially wound around the guide roller 5 and the guide roller 6. It is then slit by the integrated slitting assembly 7 and wound up by the winding roller 4. The integrated slitting assembly 7 not only performs basic slitting but also effectively eliminates static electricity on both sides of the film simultaneously. The non-metallic surface of the metallized film ionizes the surrounding air through the strong electric field generated by the electrostatic bar 707, producing a large number of positive and negative ions. These ions are blown towards the non-metallic surface of the film by the ion wind formed by compressed air. The ions attract the opposite charge on the non-metallic surface, neutralizing the negative charge with the positive ions. The electrostatic discharge (ESD) neutralizes the positive charge, thereby achieving charge balance and eliminating static electricity on the non-metallic surface. Meanwhile, the ESD roller 709 makes physical contact with the metallized surface of the film. Static charges on the metal coating are transferred to the ESD roller 709 through the contact point. The charges are then quickly conducted to the ground through the ground wire connected to the ESD roller 709, thus being neutralized. The two work together to effectively eliminate static electricity generated during the film slitting process, preventing dust and other impurities from being attracted by static electricity, thereby ensuring the slitting quality of the film and its subsequent use. At the same time, the integrated slitting assembly 7 adopts a detachable structure, which facilitates replacement and maintenance according to different slitting requirements in actual applications.

[0023] like Figure 5 , Figure 6 and Figure 7 The integrated slitting assembly 7 includes a main support and a slitting blade 710 installed between the control base 1 and the mounting base 2. The slitting blade 710 is mounted on the main support via a blade holder. In actual use, the main support serves as the basic carrier and has a detachable structure, allowing for quick loading and unloading from the control base 1 and the mounting base 2. This makes maintenance and replacement relatively quick. The slitting blade 710 enables basic slitting functions.

[0024] The main support consists of two mounting plates 701 that are detachably fixed to the control base 1 and the mounting base 2, respectively. Each mounting plate 701 is connected to a fixing plate 703 via a connecting rod 702. A fixing link 704 is provided between the two fixing plates 703. In actual use, the two mounting plates 701 are firmly connected to the control base 1 and the mounting base 2, respectively, to ensure the overall stability of the main support. The connecting rod 702 serves to connect the mounting plates 701 and the fixing plates 703. The fixing plates 703 are connected to each other via the fixing link 704 to form an integral frame structure. This structure not only enhances the strength of the main support but also makes the connection between the various components tighter and more reliable. In actual slitting operations, it can ensure the stable operation of the slitting blade 710 and improve the slitting accuracy and quality.

[0025] like Figure 6As shown, a tension detection roller 705, a guide roller 706, an anti-static bar 707, a lifting roller 708, and an anti-static eliminator roller 709 are installed between the two fixed plates 703. The film to be cut, after being wound around the guide roller 6, passes sequentially through the tension detection roller 705, guide roller 706, lifting roller 708, and anti-static eliminator roller 709 before entering the take-up roller 4. In actual use, the tension detection roller 705 can detect the tension of the film in real time and feed the detection signal back to the control host 8 on the control base 1, so as to control the speed of the unwinding roller 3 and the take-up roller 4 in a timely manner to adjust the tension, ensuring the stability of the film tension during the slitting process and avoiding slitting quality problems due to uneven tension. The guide roller 706 guides the direction of film movement, ensuring that the film accurately enters the subsequent rollers along the predetermined path. The lifting roller 708 can be adjusted up and down according to actual needs to adapt to the slitting requirements of films of different specifications, enhancing the versatility and flexibility of the equipment. The static elimination roller 709 further performs static elimination treatment on the metallized surface of the film.

[0026] An antistatic bar 707 is also installed between the two fixed plates 703. The antistatic bar 707 is located between the two guide rollers 706. In actual use, the antistatic bar 707 can effectively eliminate the static electricity generated on the non-metallic surface of the film during operation, prevent static electricity from causing adverse effects such as dust adsorption on the film, ensure the cleanliness of the film, ensure that the film is completely free of static electricity before entering the winding roller 4, improve the winding quality, and make the wound film roll more neat and compact.

[0027] like Figure 6 and Figure 7 As shown, a control groove 711 is provided in the fixed plate 703, and a slider 713 is provided in the control groove 711. The top end of the slider 713 is connected to the end of the lifting roller 708 through a guide rod 712. The guide rod 712 is rotatably connected to the end of the lifting roller 708. In actual use, by controlling the slider 713 to slide up and down in the control groove 711, the guide rod 712 can be driven to move up and down accordingly. Since the guide rod 712 is rotatably connected to the end of the lifting roller 708, the up and down adjustment of the lifting roller 708 can be realized.

[0028] A servo motor is embedded in the control slot 711. An eccentric disk 714 is connected to the output shaft of the servo motor. In actual use, after the servo motor starts, its output shaft drives the eccentric disk 714 to rotate. The special shape design of the eccentric disk 714 causes it to produce a regular eccentric motion during rotation. This eccentric motion acts on the slider 713, pushing it to slide up and down within the control slot 711. Since the slider 713 is connected to the end of the lifting roller 708 via the guide rod 712, and the guide rod 712 is connected to the end of the lifting roller 708... The end of 08 is rotatably connected, so the up and down sliding of the slider 713 will drive the guide rod 712 to move up and down accordingly, thereby realizing the precise up and down adjustment of the lifting roller 708. The lifting control is achieved by using an eccentric disk 714. On the one hand, it can achieve effective stepless adjustment. On the other hand, the characteristics of the eccentric disk 714 allow the slider 713 to easily deflect the eccentric disk 714 when the pressure is too great. This deflection method is different from the elasticity of the spring. It will not rebound directly to reset when pressure is applied, which facilitates the provision of buffer space for the film when the tension is too great.

[0029] One end of the static eliminator roller 709 is grounded through a grounding wire. In actual use, the static eliminator roller 709 can quickly conduct static electricity to the grounding wire through its special conductive material, and then the grounding wire conducts the static electricity into the ground, thereby effectively eliminating static electricity on the film surface.

[0030] A control host 8 is installed on the control base 1. The control host 8 is electrically connected to each electrical component. In actual use, the control host 8 can receive the instructions input by the operator and accurately control each electrical component according to the preset program. It can control the start, stop and speed adjustment of the servo motor, thereby accurately controlling the lifting speed and position of the lifting roller 708 to meet the slitting requirements of metallized films of different specifications.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
