Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a slitting machine for electromagnetic shielding films. Background Technology

[0002] In the production and processing of electromagnetic shielding films, slitting machines are crucial equipment. Traditional slitting machines typically have enclosed bakelite wheel side plates, making it difficult for operators to directly observe wheel wear. This hinders timely problem detection and maintenance, affecting the normal operation of the slitting machine and the slitting quality. Therefore, developing a slitting machine for electromagnetic shielding films that allows for easy observation of bakelite wheel wear is of great significance. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a slitting machine for electromagnetic shielding films, which solves the problem that the wear of the bakelite wheel is not easy to observe on the side plate of the bakelite wheel in the existing slitting machine.

[0004] This utility model proposes a slitting machine for electromagnetic shielding films, comprising a slitting machine body, an opening on the side plate of the bakelite wheel of the slitting machine, a rotating shaft mounted on the middle of the upper and lower sides of the opening, and an observation window that can rotate 180° around the shaft between the two rotating shafts; when one side of the observation window is flush with the outer wall of the body, the window and the opening are sealed around the opening; the outer wall of the body is provided with an automatic cleaning device for cleaning the surface of the outer observation window to maintain a clear field of vision.

[0005] The rotatable observation window design allows operators to easily observe the operation of the bakelite wheels from the outside and promptly identify problems such as wear. The sealing treatment effectively prevents debris and dust generated during the slitting process from entering the machine body and affecting normal operation, while also providing favorable conditions for the efficient operation of the subsequent automatic cleaning device.

[0006] Preferably, the automatic cleaning device includes two vertical guide rails, which are respectively placed on both sides of the observation window opening; the first crossbeam and the second crossbeam are laterally slidably connected between the two guide rails; the first crossbeam is provided with a window scraping mechanism, and the second crossbeam is provided with a cleaning mechanism.

[0007] The vertical guide rails provide stable guidance for the movement of the first and second crossbeams, ensuring that the scraping and cleaning mechanisms can move precisely on the observation window surface. The scraping and cleaning mechanisms work together to remove stains from the observation window surface more comprehensively and efficiently, greatly improving the cleaning efficiency and maintaining a clear field of view at all times.

[0008] Preferably, a first motor, a second motor, a first lead screw, and a second lead screw are installed on the side wall of the machine body. The first motor drives the first lead screw to rotate, and the first lead screw is threadedly connected to one end of the first crossbeam. The second motor drives the second lead screw to rotate, and the second lead screw is threadedly connected to one end of the second crossbeam. The two lead screws are located on both sides of the observation window opening. A first sliding block is installed at each end of the first crossbeam, and the first sliding block is slidably connected to the guide rail. A second sliding block is installed at each end of the second crossbeam, and the second sliding block is slidably connected to the guide rail.

[0009] The combination of the motor and the lead screw provides a stable and controllable power source for the movement of the first and second crossbeams. The sliding connection between the first and second sliding blocks and the guide rail further ensures the smoothness and stability of the crossbeam movement, enabling the window scraping and cleaning actions to be executed smoothly and accurately, thus improving the reliability of the automatic cleaning device.

[0010] Preferably, the window scraping mechanism includes a scraper, which is mounted on the side of the first crossbeam near the observation window by a spring. The length of the scraper covers the entire width of the observation window, and the spring continuously applies pressure to the scraper towards the surface of the observation window.

[0011] The continuous pressure of the spring ensures that the scraper remains in close contact with the observation window surface, effectively removing dust, debris, and other stains regardless of whether the surface is smooth. The scraper covers the entire width of the observation window, ensuring that a single swipe covers the entire glass surface, improving scraping efficiency and laying a good foundation for the subsequent cleaning mechanism.

[0012] Preferably, the cleaning mechanism includes a rotating tube rotatably connected between two second sliding blocks of the second crossbeam. The outer wall of the rotating tube has multiple sets of spray holes and is equipped with bristles covering the width of the observation window. One end of the rotating tube is sealed, and the other end is connected to a water guide pipe via a bearing. A liquid storage tank is installed on the side wall of the machine body, and a water pump is installed inside the liquid storage tank. The water pump is connected to the other end of the water guide pipe. A toothed rail is vertically installed on the side of the observation window, and a gear that meshes with the toothed rail is connected to the outer wall of one end of the rotating tube. When the second crossbeam moves, the rotating tube is rotated by meshing with the toothed rail through the gear.

[0013] The inclusion of a storage tank, water pump, and water pipe ensures a stable supply of cleaning solution. The spray nozzles and brush bristles on the rotating tube work together to spray water onto the viewing window as the tube rotates, effectively removing stubborn stains. The gear and toothed rail meshing design utilizes the movement of the second crossbeam to automatically rotate the tube, eliminating the need for an additional power unit, simplifying the structure, and improving energy efficiency.

[0014] Preferably, the side wall of the fuselage is provided with a vertical sliding groove above the opening of the observation window, and a sliding component is vertically slidably connected in the sliding groove, with a pin at the bottom of the sliding component; the upper two ends of the observation window frame are respectively provided with insertion holes that can be movably engaged with the pin.

[0015] After the observation window rotates 180°, the structure can precisely fix the position of the observation window through the engagement of the pin and the socket, ensuring that the observation window will not shake when the automatic cleaning device is working, thus guaranteeing the stability and accuracy of the cleaning work, and also improving the positioning reliability of the observation window after rotation.

[0016] Preferably, an illumination component is provided around the observation window. The illumination component consists of multiple LED lights, which are evenly distributed around the observation window, and the LED lights are electrically connected to the slitting machine control system. When the daily inspection function is activated, the control system automatically turns on the LED lights to illuminate the side of the bakelite wheel. The illumination component can effectively illuminate the observation window regardless of its rotation state.

[0017] The lighting system provides ample and even illumination for observing bakelite wheels during routine inspections, allowing operators to clearly observe even minor wear patterns. Electrical connection to the slitting machine's control system enables automatic lighting control, offering convenience and speed, enhancing the equipment's intelligence, and improving the efficiency and accuracy of inspections.

[0018] The electromagnetic shielding film slitting machine proposed in this utility model has the following beneficial effects:

[0019] With a 180° rotatable observation window, operators can easily observe the wear of the bakelite wheels. Rotating the window allows for cleaning of both sides, maintaining a clear field of vision. The automatic cleaning device's scraping and brushing mechanisms work together to effectively remove stains from the observation window surface, ensuring it remains clear at all times. This innovative 180° rotatable observation window design effectively avoids the risk of water ingress into components that could occur with cleaning devices installed inside the machine body. Operators can easily observe the wear of the bakelite wheels; by rotating the window, the outer glass can be cleaned first, then the inner glass can be flipped to the outside for cleaning, maintaining a good field of vision. The lighting system automatically activates during inspections, providing ample illumination for observing the bakelite wheels and improving the observation effect.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figures 1-4 The illustrated electromagnetic shielding film slitting machine includes a slitting machine body. The slitting machine has an opening on the side plate of its bakelite wheel. A rotating shaft 102 is mounted at the center of each of the upper and lower sides of the opening. An observation window 1, capable of rotating 180° around the shaft, is installed between the two rotating shafts 102. When one side of the observation window 1 is flush with the outer wall of the main body, the window is sealed around the opening. An automatic cleaning device is provided on the outer wall of the main body to clean the surface of the outer observation window 1 and maintain a clear field of vision.

[0035] The automatic cleaning device includes two vertical guide rails 2, positioned on either side of the opening of the observation window 1. A first crossbeam 3 and a second crossbeam 4 are laterally slidably connected between the two guide rails 2. A window scraping mechanism is mounted on the first crossbeam 3, and a cleaning mechanism is mounted on the second crossbeam 4.

[0036] A first motor 301, a second motor 401, a first lead screw 302, and a second lead screw 402 are installed on the side wall of the machine body. The first motor 301 drives the first lead screw 302 to rotate, and the first lead screw 302 is threadedly connected to one end of the first crossbeam 3. The second motor 401 drives the second lead screw 402 to rotate, and the second lead screw 402 is threadedly connected to one end of the second crossbeam 4. The two lead screws are located on both sides of the opening of the observation window 1. A first sliding block 303 is installed at each end of the first crossbeam 3, and the first sliding block 303 is slidably connected to the guide rail 2. A second sliding block 403 is installed at each end of the second crossbeam 4, and the second sliding block 403 is slidably connected to the guide rail 2.

[0037] The window scraping mechanism includes a scraper 305, which is mounted on the side of the first crossbeam 3 near the observation window 1 by a spring 304. The length of the scraper 305 covers the entire width of the observation window 1, and the spring 304 continuously applies pressure to the scraper 305 on the surface of the observation window 1.

[0038] The cleaning mechanism includes a rotating tube 404, which is rotatably connected between two second sliding blocks 403 of the second crossbeam 4. Multiple sets of spray holes 405 are opened on the outer wall of the rotating tube 404, and bristles 407 covering the width of the observation window 1 are installed. One end of the rotating tube 404 is sealed, and the other end is connected to a water guide pipe 602 via a bearing 406. A liquid storage tank 6 is installed on the side wall of the machine body, and a water pump 601 is installed inside the liquid storage tank 6. The water pump 601 is connected to the other end of the water guide pipe 602. A toothed rail 5 is vertically mounted on the side of the observation window 1. A gear 501 that meshes with the toothed rail 5 is connected to the outer wall of one end of the rotating tube 404. When the second crossbeam 4 moves, the rotating tube 404 rotates through the meshing of the gear 501 with the toothed rail 5.

[0039] A vertical sliding groove 7 is provided on the side wall of the fuselage above the opening of the observation window 1. A sliding component 701 is vertically slidably connected in the sliding groove 7, and a pin 702 is provided at the bottom of the sliding component 701. The upper ends of the window frame 101 of the observation window 1 are respectively provided with insertion holes 103 that can be movably engaged with the pin 702.

[0040] An illumination assembly consisting of multiple LED lights is installed around the observation window, evenly distributed around its perimeter. These LED lights are electrically connected to the slitting machine's control system. When the routine inspection function is activated, the control system automatically turns on the LED lights to illuminate the sides of the bakelite wheels, ensuring effective illumination regardless of the observation window's rotation position.

[0041] In this embodiment, during operation:

[0042] When it is necessary to observe the wear of the bakelite wheels, the lighting assembly is activated, and the LED lights illuminate the side of the bakelite wheels. If the observation window is dirty, the automatic cleaning device is activated. First, the second motor 401 drives the second lead screw 402, which moves the second crossbeam 4. The gear 501 on the rotating tube 404 meshes with the gear rail 5, causing the rotating tube 404 to rotate. The water pump 601 sprays the cleaning solution in the storage tank 6 through the water guide pipe 602 and the spray nozzle 405. The brush 407 cleans the observation window 1. The second lead screw can be a reciprocating lead screw, which drives the second crossbeam to clean the observation window surface back and forth several times.

[0043] After the above operations are completed, the first motor 301 drives the first lead screw 302, which in turn moves the first crossbeam 3 and the scraper 305 along the guide rail 2 to scrape and clean the surface of the observation window 1.

[0044] It is important to note that the first crossbeam should be positioned above the second crossbeam, because the scraper cleans the observation window 1 more thoroughly by scraping from top to bottom, and the scraped-off wastewater will not flow down and contaminate the observation window again.

[0045] When it is necessary to clean the other side of the observation window 1, rotate the observation window 1 180° and fix it in place by using the pin 702 to engage with the socket 103, and then start the cleaning device again for cleaning.
