[0052] An embodiment of the present application provides a device for cutting bundled materials, as Figures 1 to 13 shown, including:

[0053] A frame 1, on which a support plate 2 is provided;

[0054] At least one fixed rod 3, and the fixed rod 3 is installed on the support plate 2;

[0055] A plurality of cutter assemblies, which are arranged from top to bottom. Each cutter assembly includes:

[0056] A fixed cutter disc 4, which is installed on the fixed rod 3. A first central hole 41 is provided on each fixed cutter disc 4, and a plurality of rotating shafts 42 are provided on the fixed cutter disc 4 along the circumference of the first central hole;

[0057] A plurality of cutters 5, which are located on the fixed cutter disc 4 and correspond to the plurality of rotating shafts 42 one by one. One end of the cutter 5 is rotatably installed on the rotating shaft 42;

[0058] A moving cutter disc 6, which is rotatably installed on the fixed cutter disc 4. A second central hole 61 is provided on the moving cutter disc 6. The cutters 5 are all located in the second central hole 61. A cutter connecting rod 62 is provided in the moving cutter disc 6 corresponding to the cutters 5. One end of the cutter connecting rod 62 is connected to the moving cutter disc 6, and the other end is connected to the end of the cutter 5 away from the rotating shaft 42;

[0059] A driving mechanism for driving the moving cutter disc 6 to rotate.

[0060] It should be noted that the bundled material cutting device of the present application includes a plurality of cutter assemblies arranged from top to bottom. Specifically, the number of cutter assemblies can be 2, 3, 4... In practice, the number of cutter assemblies is determined according to the usage situation. For example, Figure 1 As shown in the figure, there are 4 cutter assemblies. Each cutter assembly includes: a fixed cutter disc 4, a moving cutter disc 6, and a plurality of cutters 5. Among them, the fixed cutter discs 4 of the plurality of cutter assemblies are fixed on the fixed rod 3 from top to bottom. A first central hole 41 is provided in the middle of the fixed cutter disc 4 (that is, the fixed cutter disc 4 is approximately annular). At the same time, a plurality of rotating shafts 42 are provided on the fixed cutter disc 4 along the circumference of the first central hole 41. The plurality of cutters 5 correspond to the plurality of rotating shafts 42 one by one. The cutter 5 is a conventional cutter in the prior art, and a cutting edge is provided at the edge of the cutter 5. One end of the cutter 5 can rotate around the rotating shaft 42. The moving cutter disc 6 is rotatably arranged on the fixed cutter disc 4. A second central hole 61 is opened in the middle of the moving cutter disc 6 (that is, the moving cutter disc 6 is approximately annular). Obviously, the diameter of the second central hole 61 is larger than the diameter of the first central hole 41, and the plurality of cutters 5 are all located within the second central hole 61. A plurality of cutter connecting rods 62 are arranged inside the moving cutter disc 6. The cutter connecting rods 62 correspond to the cutters 5 one by one. One end of the cutter connecting rod 62 is hinged to the end of the cutter 5 away from the rotating shaft 42, and the other end is hinged to the moving cutter disc 6. When the driving mechanism drives the moving cutter disc 6 to rotate in one direction, under the action of the cutter connecting rod 62, the cutter 5 also rotates around the rotating shaft 42. At this time, due to the rotation of the plurality of cutters 5, the plurality of cutters 5 move away from each other, that is, the plurality of cutters 5 open. When the driving mechanism drives the moving cutter disc 6 to rotate in the other direction, under the action of the cutter connecting rod 62, the cutter 5 also rotates around the rotating shaft 42 in the reverse direction. At this time, due to the rotation of the plurality of cutters 5, the plurality of cutters 5 move closer to each other, that is, the plurality of cutters 5 close. The working principle of the bundled material cutting device of the present application is as follows: Before use, the driving mechanism drives the moving cutter discs 6 of the plurality of cutter assemblies to rotate in one direction, so that the plurality of cutters 5 open. Then, the bundled material is placed between the cutters 5, passes through the first central hole 41, extends downward, and sequentially passes through the first central holes 41 on the plurality of fixed cutter discs 4 below. Then, the driving mechanism drives the moving cutter disc 6 to rotate in the other direction, so that the plurality of cutters 5 close. During the closing process of the plurality of cutters 5, the bundled material can be cut off. Since the bundled material cutting device of the present application includes a plurality of cutter assemblies from top to bottom, the bundled material can be cut into multiple sections of materials at one time, and the cutting efficiency of the material is greatly improved compared with the traditional cutting device.

[0061] In some embodiments, it further includes:

[0062] A first connecting rod 7 located on one side of the cutter assembly;

[0063] A plurality of second linkages 71, which correspond to the plurality of moving cutter discs 6 one by one. One end of each second linkage 71 is hinged to the moving cutter disc 6, and the other end is connected to the first linkage 7;

[0064] The driving mechanism drives the first linkage 7 to rotate, thereby driving the moving cutter disc 6 to rotate.

[0065] In the above embodiment, the first linkage 7 is vertically arranged. One end of the second linkage 71 is hinged to the moving cutter disc 6, and the other end is connected to the first linkage 7. By driving the first linkage 7 to rotate through the driving mechanism, the moving cutter disc 6 can be driven to rotate under the action of the second linkage 71. In this embodiment, by arranging the first linkage 7, driving the first linkage 7 by the driving mechanism can realize the simultaneous rotation of the plurality of moving cutter discs 6.

[0066] Specifically, in some embodiments, the driving mechanism can be a crank - connecting rod mechanism or a telescopic mechanism (such as a telescopic rod, a cylinder, etc.), and the reciprocating movement of the first linkage 7 can be realized through the driving mechanism.

[0067] In some embodiments, through - holes 21 are formed in the support plate 2 along its width direction;

[0068] The driving mechanism includes:

[0069] A motor 8, which is installed on the frame 1 and is located below the support plate 2;

[0070] A groove cam 81, which is connected to the output shaft of the motor 1;

[0071] A push rod 9, the upper end of which passes through the through - hole 21 and is hinged to a third linkage 72, the other end of the third linkage 72 is connected to the first linkage 7. A bearing 91 is provided at the lower end of the push rod 9, and the bearing 91 is located in the groove 82 on the groove cam 81;

[0072] Wherein, the rotation of the motor 8 drives the groove cam 81 to rotate, thereby realizing the reciprocating movement of the push rod 9 along the through - hole 21. The movement of the push rod 9 drives the first linkage 7 to move, thereby realizing the rotation of the moving cutter disc 6.

[0073] In the above embodiment, the driving mechanism includes a motor 8, a groove cam 81 and a push rod 9. A bearing 91 is provided at the lower end of the push rod 9, and the bearing 91 is located in the groove 82 on the groove cam 81. The upper end of the push rod 9 passes through the through - hole 21 and is hinged to one end of the third linkage 72, and the other end of the third linkage 72 is connected to the first linkage 7. When the motor 8 rotates, it drives the groove cam 81 to rotate. Under the action of the groove cam 81, the push rod 9 reciprocates along the through - hole (i.e., reciprocates along the width direction of the support plate). During the reciprocating movement of the push rod 9, the first linkage 7 is driven to reciprocate through the third linkage 72, thereby realizing the reciprocating rotation of the moving cutter disc 6.

[0074] Specifically, when the groove cam 81 rotates to move the push rod 9 to one end of the through hole, the moving cutter disc 6 rotates at this time to make the multiple cutter blades 5 open to the maximum; when the groove cam 81 rotates to move the push rod 9 to the other end of the through hole, the moving cutter disc 6 rotates at this time to make the multiple cutter blades 5 approach each other to be completely closed.

[0075] In some embodiments, a bearing connecting member 92 is fixed to the push rod 9 by screws, a bearing 91 is sleeved outside the bearing connecting member 92, and the bearing 91 is in rolling contact with the inner wall of the groove 82.

The fasteners 44 can be sleeves, nuts, etc. The fasteners 44 are screwed on the outer periphery of the fixed rod 3. When the upper and lower two fasteners 44 are tightened, the fixed cutter disc 4 can be fastened. When the distance between the upper and lower two fixed cutter discs 4 needs to be adjusted, loosen the upper and lower two fasteners 44 of the corresponding fixed cutter disc 4, then move the fixed cutter disc 4 up and down to a suitable position, and then fix the fixed cutter disc 4 by rotating the upper and lower two fasteners 44; by providing an external thread on the outer periphery of the fixed rod 3 and the fasteners 44, the distance between the upper and lower fixed cutter discs 4 can be adjusted, and thus the cutting of bundled materials of different lengths can be realized.

[0078] In some embodiments, at least one arc-shaped sliding hole 63 is formed on the moving cutter disc 6 along the circumferential direction, and a positioning post 45 is provided on the fixed cutter disc 4 corresponding to the arc-shaped sliding hole 63. When the moving cutter disc 6 rotates relative to the fixed cutter disc 4, the positioning post 45 can move along the arc-shaped sliding hole 63.

[0079] In the above embodiments, at least an arc-shaped sliding hole 63 is formed on the moving cutter disc 6 along the circumferential direction. Correspondingly, a positioning post 45 is provided on the fixed cutter disc 4. The positioning post 45 is located in the arc-shaped sliding hole 63. When the moving cutter disc 6 rotates, the positioning post 45 moves relative to the arc-shaped sliding hole 63; obviously, the length of the arc-shaped sliding hole 63 determines the rotation amplitude of the moving cutter disc 6.

[0080] In some embodiments, when the moving cutter disc 6 rotates and the positioning post 45 abuts against one side of the arc-shaped sliding hole 63, the multiple cutter blades 5 open to the maximum; when the moving cutter disc 6 rotates and the positioning post 45 abuts against the other side of the arc-shaped sliding hole 63, the multiple cutter blades 5 approach each other to be completely closed.

[0081] In some embodiments, a blanking hole 22 is formed in the support plate 2 corresponding to the cutting tool assembly. By providing the blanking hole 22, the cut material drops downward through the blanking hole 22.

[0082] In some embodiments, a blanking box 11 is provided on the frame 1 and corresponding to the blanking hole 22 below the support plate 2. By providing the blanking box 11 on the frame 1, the cut material drops downward through the blanking hole 22 into the blanking box 11.

[0083] Specifically, the frame 1 is further provided with a base 12, and the blanking box 11 and the motor 8 are both provided on the base 12.

Correspondingly, both the cutting tool 5 and the cutter connecting rod 62 are provided in five. One end of the cutter connecting rod 62 is hinged to one end of the cutting tool 5, and the other end is hinged to the moving cutter disc 6 and close to one side of the arc-shaped sliding hole 63. Refer to Figure 4 As shown, it shows that the number of the cutting tools 5 is five, Figure 4 and the five cutting tools 5 are completely closed. In practice, the number of the arc-shaped sliding holes 63 can be determined according to the usage situation, and the number of the arc-shaped sliding holes 63 can be set to 2, 3, 4... etc.

[0086] In some embodiments, the cutter connecting rod 62 is arc-shaped bent.

[0087] In some embodiments, it further includes a transmission shaft 83. One end of the transmission shaft 83 is connected to the groove cam 81, and the other end is connected to the output shaft of the motor 8 through a coupling 84.

[0088] In the above embodiments, the rotation of the motor 8 drives the transmission shaft 83 to rotate, and the rotation of the transmission shaft 83 drives the groove cam 81 to rotate.
