DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] like Figure 1 to Figure 2 As shown, a double-cutter mechanism includes a frame 1, a first cutting assembly 2 is slidably provided on one side of the frame 1, a second cutting assembly 3 is slidably provided on the other side of the frame 1, the first cutting assembly 2 is provided with a floating knife frame 204, a first cutting knife 201 is provided above the floating knife frame 204, and the second cutting assembly 3 is provided with a second cutting knife 301, and the first cutting knife 201 and the second cutting knife 301 are used correspondingly; during installation design, the first cutting knife 201 and the second cutting knife 301 are arranged in an upper and lower dislocation and overlapped arrangement. Combined with the figure, in this embodiment, the first cutting knife 201 slides on the upper surface of the second cutting knife 301, and the first cutting knife 201 is inserted into the second cutting knife 301. When the material is being cut, the first cutting assembly 2 and the second cutting assembly 3 are driven to slide on the frame 1 at the same time, so that the first cutting knife 201 and the second cutting knife 301 are separated from each other, so that a cutting opening 7 is formed between the first cutting assembly 2 and the second cutting assembly 3, so that the material package is placed at the cutting opening 7. When cutting, the first cutting assembly 2 and the second cutting assembly 3 are driven to slide on the frame 1, so that the first cutting knife 201 and the second cutting knife 301 are separated from each other so that the cutting opening 7 is closed, thereby cutting the material package (the material package is in the shape of a long strip, and is cut into independent packages by the action of the first cutting knife 201 and the second cutting knife 301); Figure 4 , Figure 6 , Figure 8It can be seen that the edges of the cutting opening 7 formed by the first cutting knife 201 and the second cutting knife 301 are wavy-toothed, and the wavy-toothed edge of the first cutting knife 201 and the wavy-toothed edge of the second cutting knife 301 are staggered and overlapped. Therefore, when they meet and intersect, while cutting both sides of the material package, there will be no collision between the first cutting knife 201 and the second cutting knife 301, and there will be no direct collision and edge wear.

[0034] The first cutting blade 201 and the second cutting blade 301 are arranged to overlap each other. The overlapping arrangement means that the upper and lower parts are overlapped.

[0035] The first cutting knife 201 and the second cutting knife 301 can move in the same direction or in opposite directions. When the first cutting knife 201 and the second cutting knife 301 move in opposite directions, a cutting opening 7 is formed between them, and the material package moves in the cutting opening 7. When the first cutting knife 201 and the second cutting knife 301 move in the same direction, the cutting opening 7 is closed to cut the material package.

[0036] Specifically, Figures 3 to 9 As shown, the first cutting component 2 includes a first tool holder 202, a first slider 205 is fixedly connected above the first tool holder 202, a first connecting shaft 203 is connected to the first tool holder 202, a floating tool holder 204 is rotatably provided at the end of the first tool holder 202, and the first cutting knife 201 is connected above the floating tool holder 204; the second cutting component 3 includes a second tool holder 302, a second slider 304 is connected above the second tool holder 302, a second connecting shaft 303 is connected to the second tool holder 302, and the second cutting knife 301 is connected to the end of the second tool holder 302; the first connecting shaft 203 and the second connecting shaft 303 are both rotatably connected to a connecting member 4, and are connected to one end of the connecting member 4, and the other end of the connecting member 4 is rotatably connected to an eccentric shaft 5; the eccentric shaft 5 is on a driving block 6, and the driving block 6 is connected to the motor shaft of the motor.

[0037] Specifically, Fig.10 , Fig.11As shown, the drive block 6 is provided with a motor shaft mounting hole 601, and the motor shaft of the motor is connected to the motor shaft mounting hole 601; the motor shaft mounting hole 601 is connected to a clamping opening 602 in the side cut; the drive block 6 is also longitudinally penetrated with a tightening hole 603 corresponding to the clamping opening 602; the eccentric shaft 5 is located on the side of the motor shaft mounting hole 601. The function of the above structure is that after the motor shaft of the motor is inserted and connected to the motor shaft mounting hole 601, the clamping opening 602 is narrowed by inserting a bolt into the tightening hole 603 and tightening the nut at the tail, so as to achieve the purpose of locking and fixing the motor shaft of the motor in the motor shaft mounting hole 601, and the motor shaft of the motor rotates, driving the drive block 6 to rotate. From the above structure, it can be seen that when the motor shaft of the motor rotates, it drives the drive block 6 to rotate, and also drives the eccentric shaft 5 to rotate with the motor shaft mounting hole 601 as the center.

[0038] from Fig. 9 It can be seen that a first slide rail 101 is provided on one side of the bottom surface of the frame 1, and a second slide rail 102 is provided on the other side of the bottom surface of the frame 1. Figure 3 It can be seen that the front and rear sides of the upper surfaces of the second slider 304 and the first slider 205 are both clamped, and correspondingly, the first slider 205 is slidably connected to the first slide rail 101 in a clamping manner, and the second slider 304 is slidably connected to the second slide rail 102 in a clamping manner, that is, the first slider 205 and the second slider 304 can be opened and closed along the directions of the first slide rail 101 and the second slide rail 102 respectively.

[0039] The driving principle of the first cutting assembly 2 is the same as that of the second cutting assembly 3. The following description will be made taking the first cutting assembly 2 as an example (combined with Figure 5 , Fig. 9 As shown above, after starting the motor, the eccentric shaft 5 is driven by the driving block 6 to rotate with the motor shaft mounting hole 601 as the center, thereby also driving the end of the connecting member 4 connected to the eccentric shaft 5 to rotate, so the other end of the connecting member 4 will push the first connecting shaft 203; the first tool holder 202 is fixed to the first slider 205, and the first slider 205 is slidably connected to the first slide rail 101, that is, the movement trajectory of the first slider 205 and the first tool holder 202 has been limited, so the force acting on the first connecting shaft 203 drives the first tool holder 202 to move back and forth along the direction of the first slide rail 101.

[0040] Similarly, the second cutting assembly 3 also adopts the same structural principle as above to drive the second tool holder 302 to move forward and backward along the second slide rail 102; that is, the first cutting knife 201 and the second cutting knife 301 are driven to move toward or away from each other.

[0041] The first cutting knife 201 is arranged above the second cutting knife 301, and the lower end surface of the first cutting knife 201 is provided with an upper tooth 2011, and the upper end surface of the second cutting knife 301 is provided with a lower tooth 3011. The upper teeth 2011 and the lower teeth 3011 are arranged alternately. When the first cutting knife 201 and the second cutting knife 301 are close to each other, the material package will be cut under the action of the upper teeth 2011 and the lower teeth 3011; the upper teeth 2011 and the lower teeth 3011 are both wavy teeth.

[0042] The floating tool holder 204 has first connection holes 2041 at both ends to accommodate the spring installation, and the first tool holder 202 has second connection holes 2021 at both ends. The first connection holes 2041 correspond to the second connection holes 2021. Figure 7 As shown, both ends of the floating tool holder 204 are rotatably arranged on the first tool holder 202 through the connecting column 2042, so that the floating tool holder 204 can rotate relative to the first tool holder 202, and the spring is installed on the first connecting hole 2041, and the second connecting hole 2021 is provided with an internal thread, and a bolt is used to pass through the spring and threadedly connect with the second connecting hole 2021; the top end of the spring is connected to the bolt head, and the bottom end of the spring is connected to the inner surface of the lower end of the first connecting hole 2041; that is, the spring has an elastic downward pressing effect on the floating tool holder 204; and from Figure 7 , Figure 8 , Fig.12 As can be seen, the first connection hole 2041 is in the shape of an oblong, and the hole width of the first connection hole 2041 is larger than the diameter of the bolt, so it will not limit the rotation of the floating knife holder 204; if the first cutting knife 201 is subjected to force and transmitted to the floating knife holder 204 during cutting, the floating knife holder 204 will slightly rotate upward with the connecting column 2042 as the center of the circle, and the spring is in a compressed state at this time. When the force is released, the floating knife holder 204 will be pressed down and reset under the action of the spring. Since the first cutting knife 201 is fixed on the floating knife holder 204, that is, in this structure, the first cutting knife 201 has space to float upward relative to the second cutting knife 301. The purpose of this design is to allow the first cutting knife 201 and the second cutting knife 301 to fit together for cutting, while the first cutting knife 201 is not tightly pressed on the second cutting knife 301, that is, the two are not in hard contact, to avoid excessive pressure on the contact surface between the first cutting knife 201 and the second cutting knife 301 and wear during operation.

[0043] like Figure 8 As shown, the bottom of the first connecting hole 2041 is elliptical, that is, the hole width of the connecting hole 2041 mentioned above is larger than the diameter of the bolt. When the floating tool holder 204 rotates up and down, the first connecting hole 2041 has movement space relative to the bolt.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
