As shown in fig. 5, a pressing plate 513 is fixed on both sides of the threading opening 511 in the tool holder 51, and a relief notch (not shown) is provided on a surface of the pressing plate 513 facing the inner surface of the tool holder 51. When the fixed blade 52 is mounted, both sides of the fixed blade 52 are respectively embedded in the two yielding notches, and then the two pressing plates 513 are fixed with the tool post 51 by means of threading screws, so that the pressing plates 513 keep pressing the fixed blade 52 towards the tool post 51 to fix the fixed blade 52.
The movable blade 53 is located on the other side of the tape threading port 511, and the movable blade 53 is restrained from sliding relative to the fixed blade 52 between the two pressing plates 513. The structure for restricting the sliding of the movable blade 53 may be, as shown in fig. 6 and 7, such that both sides of the movable blade 53 extend toward the fixed blade 52 to form the extension portions 532, and both extension portions 532 are attached to the surface of the fixed blade 52. The elastic piece 55 is fixed on both sides of the tool apron 51, specifically, one end of the elastic piece 55 may be fixed on the pressing plate 513 by threading a screw. The other end of the elastic piece 55 is bent toward the fixed blade 52 to form an elastic portion 551, and the two elastic portions 551 press the two extending portions 532 against the fixed blade 52, so that the structure of the elastic piece 55 can limit the movable blade 53 to be always stuck to the surface of the fixed blade 52 during sliding relative to the fixed blade 52, and the second edge portion 531 of the movable blade 53 can be closely contacted with the first edge portion 521 of the fixed blade 52 to smoothly cut the adhesive tape 21. Referring to fig. 8 again, the movable blade 53 is fixed on the sliding seat 54, the two sides of the sliding seat 54 are fixed with the limiting columns 541, the two sides of the tool apron 51 are provided with the through limiting holes 512, the two limiting columns 541 are respectively adapted to penetrate into the two limiting holes 512, and the movable blade 53 is limited to be far away from one end of the extension portion 532 by the structure, so that the movable blade 53 can only slide linearly relative to the fixed blade 52. Further, the movable blade 53 is fixed to the slider 54 by means of screw insertion to facilitate the installation or replacement of the movable blade 53.
As shown in fig. 8, the movable blade 53 is recessed to form a knife edge corresponding to one side of the fixed blade 52, the knife edge forms an isosceles triangle structure, two equal sides of the isosceles triangle structure form second blade parts 531, and the two second blade parts 531 are used for cutting the adhesive tape. When the movable blade 53 slides onto the fixed blade 52 to cut the adhesive tape 21, the process of cutting the second blade 531 on both sides of the movable blade 53 toward the middle can be formed, which can reduce the resistance of the movable blade 53 to cut the adhesive tape 21 and can reduce the moment required to drive the movable blade 53 to slide, which is advantageous for energy saving.
With continued reference to fig. 1, the present application further includes a cutting motor 561 for driving the movable blade 53 to slide, an eccentric 562, and a swing link 564. The cutting motor 561 is fixed on the mounting frame of the case sealer, and the output shaft of the cutting motor 561 is fixed with the eccentric wheel 562, and the eccentric wheel 562 surface is deviated from the circle center to fix the eccentric pin 563. The position of the swing rod 564 near the middle is limited to rotate relative to the tool holder 51, specifically, a pin 5641 passes through the swing rod 564 and then is fixed on the tool holder 51, so that the swing rod 564 rotates relative to the tool holder 51 with the pin 5641 as the axis. One end of the swing rod 564 is limited to rotate relative to the movable blade 53, and the connection manner may be that both ends of the swing rod 564 are provided with kidney-shaped holes 5642, and the kidney-shaped holes 5642 at one end are sleeved outside the pin shaft 5641 fixed to the movable blade 53, so that one end of the swing rod 564 rotates relative to the movable blade 53. The kidney-shaped hole 5642 at the other end of the swing link 564 is sleeved outside the eccentric pin 563 such that the other end of the swing link 564 is restricted to move relative to the eccentric pin 563. When the cutting motor 561 works, the cutting motor 561 drives the eccentric wheel 562 to rotate to drive the eccentric pin 563 to rotate, and the waist-shaped hole 5642 of the swing rod 564 is driven to swing up and down by the rotation of the eccentric pin 563, so that the swing rod 564 drives the movable blade 53 to slide towards the fixed blade 52 or slide away from the fixed blade 52 by swinging.
As shown in fig. 9, when the cutting motor 561 drives the eccentric 562 to rotate until the eccentric pin 563 is located below, at this time, the end of the swing link 564 is pushed downward by the eccentric pin 563, and one end of the swing link 564 connected with the movable blade 563 swings upward, so that the movable blade 53 slides toward the fixed blade 52, and the adhesive tape 21 is cut off. Referring again to fig. 10, when the cutting motor 561 drives the eccentric 562 to rotate until the eccentric pin 563 is located above, at this time, the end of the swing link 564 is pushed upward by the eccentric pin 563, and the end of the swing link 564 connected with the movable blade 53 swings downward to make the movable blade 53 downward, i.e., away from the fixed blade 52, so as to ensure that the gap between the fixed blade 52 and the movable blade 53 is at a maximum when the movable blade 53 stops, so that the adhesive tape 21 can pass smoothly.
In addition, the present application further includes a distance sensor 565 and a control module (not shown), wherein the distance sensor 565 is fixed at a position outside the side edge of the eccentric 562, such as above the eccentric 562 shown in fig. 9 and 10, and a connecting rod is fixed on the mounting frame of the case sealer to fix the distance sensor 565. The distance sensor 565 may be a proximity switch, the control module may be a PLC controller in the case sealer, and the control module receives a signal from the distance sensor 565 to control the cutting motor 561 to be suspended, and the opening of the cutting motor 561 may be controlled by outputting a signal to the control module through an operation panel or a key of the case sealer. The distance sensor 565 senses the position of the eccentric pin 563, when the eccentric pin 563 rotates upwards to be located above the eccentric wheel 562, the distance sensor 565 is triggered, the distance sensor 565 sends a signal to the control module, the control module controls the cutting motor 561 to drive the eccentric wheel 562 to rotate until the movable blade 53 is driven by the swing rod 564 to be far away from the fixed blade 52 and then stop, and the cutter device is reset and waits for the next cutting instruction.
In summary, the knife edge of the movable blade 53 is designed into an isosceles triangle structure, when the movable blade 53 slides towards the fixed blade 52 to cut the adhesive tape 21, the two second edge parts 531 in the isosceles triangle structure can form a cutting process from two sides of the adhesive tape 21 to the middle, so that the resistance of the movable blade 53 to cut the adhesive tape 21 can be reduced, the adhesive tape 21 with larger toughness can be cut conveniently, and the moment required for driving the movable blade 53 to slide can be reduced, thus being beneficial to saving the electric energy required by the cutting motor 561. In addition, in the process of cutting the adhesive tape 21, the position of the movable blade 53 relative to the fixed blade 52 can be controlled by sensing the position of the eccentric pin 563 through the distance sensor 565, so that after the movable blade 53 slides towards the fixed blade 52 to cut the adhesive tape 21, the movable blade 53 automatically resets to be far away from the fixed blade 52, and the adhesive tape 21 can smoothly pass through the gap 511 between the movable blade 53 and the fixed blade 52, thereby being convenient for re-packaging and cutting.
The foregoing is merely illustrative of specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any insubstantial modification of the present application by using the design concept shall fall within the scope of the present application.
