Description

Technical Field

[0001] This application relates to the field of static electricity elimination technology, and in particular to a static electricity elimination device for a slitting machine. Background Technology

[0002] Films are used to wrap the surface of items to prevent them from being contaminated or corroded during production, processing, transportation, storage and use, thus protecting the original luster of the item's surface.

[0003] To produce films suitable for various widths, a film often needs to be slit according to an adjusted blade. Therefore, plastic films are placed on a slitting machine for slitting. Existing slitting machines include a frame, an unwinding roller, a winding roller, and a blade mounted on the frame. The blade is used to slit the film into different widths. Furthermore, various traction rollers are set between the unwinding roller and the winding roller to wind the slit film onto the surface of the winding roller.

[0004] During the slitting process, contact and friction between the plastic film and components such as the traction rollers can lead to electron transfer, resulting in static electricity. Static electricity can cause the films to adhere to each other, making them difficult to peel off and hindering the processing effect and winding quality in subsequent processing. Utility Model Content

[0005] In order to remove static electricity generated during the slitting process of the film, this application provides an antistatic device for a slitting machine.

[0006] The static eliminator for a slitting machine provided in this application adopts the following technical solution:

[0007] An antistatic device for a slitting machine includes an antistatic roller slidably mounted on a frame and a sliding device for driving the antistatic roller to slide. The antistatic roller is arranged parallel to a take-up roller, and the sliding device is used to drive the antistatic roller toward / away from the side of the take-up roller.

[0008] By adopting the above technical solution, the static electricity generated by the film can be eliminated by setting an antistatic roller, so as to maintain the subsequent processing effect and winding quality of the film; and by setting a sliding device, the distance between the antistatic roller and the winding roller can be adjusted, so as to maintain the distance between the film on the outer surface of the winding roller and the antistatic roller, thus maintaining the antistatic effect on the film.

[0009] Optionally, the sliding device includes two sets of linear modules mounted on the frame, and the two ends of the static elimination roller are respectively connected to the two sets of linear modules.

[0010] By adopting the above technical solution and setting a linear module, the static elimination roller can be driven to slide on the frame to change the distance between the static elimination roller and the take-up roller.

[0011] Optionally, the sliding device includes slides mounted at both ends of the static elimination roller, a guide rod mounted on the frame, a threaded rod rotatably mounted on the frame, and a first motor for driving the threaded rod to rotate; one of the slides is slidably mounted on the guide rod, and the other slide is threadedly connected to the threaded rod.

[0012] By adopting the above technical solution, the first motor can be turned on to drive the threaded rod to rotate on the frame; since the slide at one end of the static elimination roller is threadedly connected to the threaded rod and guided by the guide rod, the static elimination roller can slide to change the distance between the static elimination roller and the take-up roller.

[0013] Optionally, a first gear is provided at the end of the threaded rod away from the frame, and a second gear for meshing with the first gear is installed on the output shaft of the first motor.

[0014] By adopting the above technical solution, the meshing of the first gear and the second gear can drive the threaded rod to rotate, and this design can make the connection between the first motor and the threaded rod more compact and reduce the space occupied.

[0015] Optionally, the static eliminator roller is equipped with a laser rangefinder sensor, which is used to measure the distance between the static eliminator roller and the film on the surface of the take-up roller. The laser rangefinder sensor is electrically connected to the sliding device.

[0016] By adopting the above technical solution and setting up a laser rangefinder, the distance between the film on the outer wall of the take-up roller and the static elimination roller can be monitored in real time. As the thickness of the film wound on the outer wall of the take-up roller increases, the position of the static elimination roller on the frame is slid to keep the distance between the static elimination roller and the film on the outer wall of the take-up roller consistent, thus maintaining the static elimination effect on the film.

[0017] Optionally, the frame is equipped with a speed sensor for measuring the rotational speed of the take-up roll, and the speed sensor is electrically connected to the static elimination roll.

[0018] By adopting the above technical solution, a speed range is set in the slitting machine, and the speed of the take-up roller is measured by a speed sensor. When the speed of the take-up roller increases to the speed range, the static elimination roller is turned on. When the speed of the take-up roller exceeds the set speed range, the static elimination effect is relatively poor, and the static elimination roller is disconnected, saving energy.

[0019] Optionally, mounting blocks are installed at both ends of the static elimination roller, and the sliding device has mounting grooves for the mounting blocks to be inserted into; the inner wall of the mounting groove has a movable groove, and a fixed block is movably installed in the movable groove. The mounting block has a fixing groove for the fixed block to be inserted into; a spring is provided between the fixed block and the inner wall of the movable groove, and the elastic force of the spring is used to drive the fixed block to be inserted into the fixing groove under normal conditions.

[0020] By adopting the above technical solution, the insertion and connection of the fixing block and the fixing groove can install the mounting block in the mounting groove, thereby realizing the detachable connection between the static eliminator and the sliding device, and enabling the static eliminator roller to be removed from the frame for maintenance, thus improving the maintenance effect.

[0021] Optionally, the fixing block is provided with a guide surface for guiding the fixing block into the movable groove.

[0022] By adopting the above technical solution, during the process of inserting the mounting block into the mounting groove, the fixed block enters the movable groove under the guidance of the guide surface, thereby improving the installation efficiency of the static elimination roller and the frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up an antistatic roller, static electricity generated by the film can be eliminated to maintain the subsequent processing effect and winding quality of the film; and by setting up a sliding device, the distance between the antistatic roller and the winding roller can be adjusted so that the distance between the film on the outer surface of the winding roller and the antistatic roller remains consistent, thus maintaining the antistatic effect on the film.

[0025] 2. By setting up a laser rangefinder, the distance between the film on the outer wall of the take-up roller and the static eliminator roller can be monitored in real time. When the film thickness on the outer wall of the take-up roller changes, the static eliminator roller is slid to keep the distance between the static eliminator roller and the film on the outer wall of the take-up roller consistent, thus maintaining the static eliminator effect on the film.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] Example 1:

[0033] This application discloses an antistatic device for a slitting machine 3.

[0034] Reference Figure 1 An antistatic device for a slitting machine 3 is installed on the slitting machine 3 and includes an antistatic roller 1 and a sliding device 2. The slitting machine 3 includes a frame 31, an unwinding roller 33, a take-up roller 32, a traction roller 34, and a cutting assembly 35 installed on the frame 31. The traction roller 34 is located between the unwinding roller 33 and the take-up roller 32. The antistatic roller 1 is slidably installed on the frame 31, and the sliding device 2 is used to drive the antistatic roller 1 to slide on the frame 31. The frame 31 is provided with a speed sensor for measuring the rotational speed of the take-up roller 32, and the speed sensor is electrically connected to the antistatic roller 1.

[0035] In this embodiment, the sliding device 2 includes two sets of linear modules 21, which are spaced apart along the width direction of the take-up roller 32. The two ends of the static eliminator roller 1 are respectively connected to the slider 211 of the linear module 21. The static eliminator is equipped with a laser rangefinder sensor, which is electrically connected to the linear module 21.

[0036] The laser rangefinder can monitor the distance between the film on the outer wall of the take-up roller 32 and the static elimination roller 1 in real time. As the thickness of the film wound on the outer wall of the take-up roller 32 increases, it drives the static elimination roller 1 to slide on the frame 31 so that the distance between the static elimination roller 1 and the film on the outer wall of the take-up roller 32 remains consistent, thus maintaining the static elimination effect on the film.

[0037] Reference Figure 2 and Figure 3The static elimination roller 1 has mounting blocks 4 installed at both ends. The slider 211 of the linear module 21 has a mounting groove 22 for the mounting block 4 to be inserted. The outer wall of the mounting block 4 has a movable groove 41, and a fixed block 42 is movably installed in the movable groove 41. The mounting block 4 also has a fixing groove 23 for the fixed block 42 to be inserted. The insertion and engagement of the fixed block 42 and the fixing groove 23 can fix the mounting block 4 in the mounting groove 22.

[0038] A guide surface 44 is provided on the side of the fixed block 42 near the mounting groove 22, and a positioning surface is provided on the side of the fixed block 42 away from the mounting groove 22; the distance between the guide surface 44 and the positioning surface gradually increases from the side away from the movable groove 41 to the side near the movable groove 41; the guide surface 44 is provided to guide the fixed block 42 into the movable groove 41, so as to improve the insertion efficiency between the mounting block 4 and the slider 211.

[0039] A spring 43 is provided between the fixed block 42 and the inner wall of the movable groove 41. The elastic force of the spring 43 is used to drive the fixed block 42 to move away from the movable groove 41; that is, the elastic force of the spring 43 is used to drive the fixed block 42 to be inserted into the fixed groove 23 under normal conditions, thereby increasing the stability of the mounting block 4 inserted into the mounting groove 22.

[0040] The upper wall of the mounting block 4 has an unlocking groove 45 that communicates with the movable groove 41. An unlocking rod 46 is slidably installed in the unlocking groove 45, and one end of the unlocking rod 46 is connected to the fixed block 42. By moving the unlocking rod 46 in the unlocking groove 45, the fixed block 42 can be moved into the movable groove 41 to cancel the connection between the mounting block 4 and the inner wall of the mounting groove 22.

[0041] The implementation principle of Embodiment 1 of this application is as follows:

[0042] By setting the static elimination roller 1, the static electricity generated by the film can be eliminated, so as to maintain the subsequent processing effect and winding quality of the film; by setting the sliding device 2, the distance between the static elimination roller 1 and the winding roller 32 can be adjusted, so as to maintain the distance between the film on the outer surface of the winding roller 32 and the static elimination roller 1, and maintain the static elimination effect on the film.

[0043] Example 2:

[0044] This application discloses an antistatic device for a slitting machine 3.

[0045] Reference Figure 4The difference between Embodiment 2 and Embodiment 1 is that the sliding device 2 includes two slides 24, a guide rod 25 fixed to the frame 31, a threaded rod 26 rotatably mounted on the frame 31, and a first motor 27 for driving the threaded rod 26 to rotate. The guide rod 25 and the threaded rod 26 are spaced apart along the length of the take-up roller 32. One slide 24 is slidably mounted on the guide rod 25, and the other slide 24 is threadedly mounted on the threaded groove.

[0046] Mounting slot 22 is provided for slide 24 for detachable connection with mounting block 4; first motor 27 is mounted on frame 31, and second gear 29 is mounted on the output shaft of first motor 27; first gear 28 is mounted on the end of threaded rod 26 away from frame 31, and second gear 29 meshes with first gear 28.

[0047] The implementation principle of Embodiment 2 of this application is as follows:

[0048] By turning on the first motor 27, the threaded rod 26 can be driven to rotate on the frame 31; since the slide 24 at one end of the static elimination roller 1 is threadedly connected to the threaded rod 26, and under the guidance of the guide rod 25, the static elimination roller 1 can slide, thereby changing the distance between the static elimination roller 1 and the take-up roller 32.

[0049] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
