Description

Technical Field

[0001] This utility model relates to the field of slitting knife assembly technology, specifically an anti-static slitting knife assembly. Background Technology

[0002] Slitting blade sets are key tool combinations for cutting wide materials into narrow ones, playing a significant role in the processing of metal coils, films, paper, and leather. They achieve efficient and precise cutting by utilizing high-speed rotating blades in contact with the material. The blades are made from carefully selected high-hardness alloy steel or powder metallurgy materials, and after fine grinding, the cutting edges are extremely sharp and possess excellent wear resistance. Some high-end blade sets utilize special processes to reduce material adhesion, significantly improving cutting quality. During operation, the slitting blade set ensures coordinated operation of the upper and lower blade shafts, resulting in smooth, burr-free cutting edges. It is extremely convenient for operators, with a simple and intuitive interface. The slitting blade set operates smoothly, with excellent vibration and noise control, and can adapt to multi-variety, small-batch production modes, making it a powerful tool for improving slitting efficiency and yield.

[0003] However, in existing technologies, slitting knife sets are prone to generating static electricity during cutting. Static electricity can attract dust and impurities from the air, affecting the appearance quality of the product. Therefore, we need an anti-static slitting knife set. Utility Model Content

[0015] 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.

[0016] This utility model embodiment provides an anti-static slitting knife assembly, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a brake box 3 on one side of the support frame 2, a grounding wire 4 on one side of the brake box 3, a blade post 5 inside the support frame 2, a blade assembly 6 on the outer wall of the blade post 5, an adjustment component 7 on the outer wall of the blade post 5, and a moving component 8 on the top of the base 1. The blade assembly 6 includes a circular blade 601, which is disposed on the outer wall of the blade post 5. The outer wall of the circular blade 601 is provided with an adhesive layer 602, a conductive layer 603, and a protective layer 604. The circular blade 601 is first coated with an adhesive layer 602 to enhance the bonding force with the substrate, then coated with a conductive layer 603 to provide anti-static function, and finally coated with a protective layer 604 to improve wear resistance and corrosion resistance. When cutting materials, the static charge accumulated on the circular blade 601 is quickly transferred to the grounding wire 4 through the conductive layer 603, preventing the charge from accumulating locally on the blade surface.

[0017] Furthermore, such as Figure 2 and Figure 3As shown, a conductive layer 603 is provided on the circular blade 601, and the conductive layer 603 is a carbon nanotube coating, which has high conductivity and provides anti-static function.

[0018] This utility model embodiment provides an anti-static slitting knife assembly, such as... Figure 1 and Figure 4 As shown, the movable component 8 includes a fixed plate 801, which is fixedly connected to the top of the base 1. A turntable 802 is rotatably connected to one side of the fixed plate 801, and a threaded rod 803 is fixedly connected to one side of the turntable 802. A threaded sleeve 804 is threadedly connected to the outer wall of the threaded rod 803. A limiting groove 805 is fixedly connected to the top of the base 1. A movable plate 806 is fixedly connected to the top of the threaded sleeve 804, and a fixed column 807 is fixedly connected to the top of the movable plate 806. Rotating the turntable 802 causes the threaded rod 803 to rotate inside the threaded sleeve 804, causing the threaded sleeve 804 to move along the outer wall of the threaded rod 803. The threaded sleeve 804 drives the movable plate 806 to move, causing the movable plate 806 to slide along the outer wall of the limiting groove 805. The movable plate 806 drives the fixed column 807 to move.

[0019] Furthermore, such as Figure 4 As shown, the turntable 802 forms a movable structure with the threaded rod 803 and the threaded sleeve 804. One end of the threaded rod 803 is fixedly connected to one side of the turntable 802, and the outer wall of the threaded rod 803 is threadedly connected to the inside of the threaded sleeve 804. By rotating the turntable 802, the threaded rod 803 is driven to rotate inside the threaded sleeve 804, which allows the threaded sleeve 804 to move along the outer wall of the threaded rod 803.

[0020] This utility model embodiment provides an anti-static slitting knife assembly, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the adjustment assembly 7 includes a gear 701, which is fixedly connected to the outer wall of the cutter post 5. A limit post 702 is fixedly connected to one side of the cutter post 5. A fixed platform 703 is fixedly connected to one side of the fixed post 807. A limit ring 704 is rotatably connected inside the fixed platform 703. A protrusion 705 is fixedly connected to the outer wall of the cutter post 5. A threaded hole 706 is opened inside the protrusion 705. A collar 707 is provided on the outer wall of the cutter post 5. A groove 708 is opened inside the collar 707. The wall is equipped with bolts 709. The matching circular blade 601 and collar 707 are placed on the blade post 5 and engaged with the protrusion 705. The blade spacing is then adjusted according to the required slitting width. After adjustment, the bolts 709 are tightened so that one end of the bolt passes through the collar 707 and extends into the protrusion 705 to be threaded into the threaded hole 706. If further adjustment is required, the bolts 709 can be tightened to disengage the bolt from the protrusion 705. The collar 707 and the circular blade 601 are then moved to the required distance and fixed.

[0021] Furthermore, such as Figure 5 and Figure 6 As shown, the blade post 5 forms a locking structure with the collar 707 through the protrusion 705, and the shape and size of the protrusion 705 match the shape and size of the groove 708. The outer wall of the protrusion 705 fits against the inner wall of the groove 708, which can fix the collar 707 on the outer wall of the blade post 5 and prevent it from rotating, thus improving the connection effect between the blade post 5 and the collar 707.

[0022] Furthermore, such as Figure 5 and Figure 6 As shown, the collar 707 is fixed to the protrusion 705 by bolt 709, and one end of bolt 709 passes through the collar 707 and extends into the interior of the protrusion 705 and is threadedly connected to the threaded hole 706. The collar 707 can be fixed to the protrusion 705 by tightening the bolt 709, and can be detached when tightened in the opposite direction, which improves the detachability of the collar 707.

[0023] Working principle: First, an adhesive layer 602 is sprayed onto the circular blade 601 to enhance the bonding force with the substrate. Then, a conductive layer 603 is sprayed to provide anti-static function. Finally, a protective layer 604 is sprayed to improve wear resistance and corrosion resistance. After spraying, the circular blade 601 and the collar 707 are placed on the blade post 5 and engaged with the protrusion 705. The blade spacing is then adjusted according to the required slitting width. After adjustment, the bolt 709 is tightened so that one end passes through the collar 707 and extends into the protrusion 705, connecting with the threaded hole 706. If further adjustment is needed later, the bolt 709 can be tightened to disengage it from the protrusion 705. Then, the collar 707 and the circular blade 601 are moved to the required distance and fixed. After the blades are installed, the turntable can be rotated. 802 causes the threaded rod 803 to rotate inside the threaded sleeve 804, causing the threaded sleeve 804 to move along the outer wall of the threaded rod 803. The threaded sleeve 804 drives the moving plate 806 to move, causing the moving plate 806 to slide along the outer wall of the limiting groove 805. The moving plate 806 drives the fixed column 807 to move, causing the fixed column 807 to drive the fixed platform 703 to move, which in turn causes the fixed platform 703 to drive the internal limiting ring 704 to move, so that the limiting ring 704 and the limiting column 702 are in contact. At this time, the machine can be started. The upper and lower blade columns 5 can be connected by gear 701 to achieve synchronous rotation. When cutting materials, the static charge accumulated on the circular blade 601 is quickly transferred to the grounding wire 4 through the conductive layer 603, avoiding the local accumulation of charge on the blade surface.

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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
