[0040] The embodiment of the present application discloses a cardboard cutting device.

The side of the first panel 15 is slidably provided with a second panel 16 and is staggered with each other, and the second panel 16 is slidably provided with the two inner lining plates 4. , and two outer lining plates 5 are fixedly provided on the surface of the two inner lining plates 4 away from the first panel 15, and the two outer lining plates 5 have the same structure and installation method, and upper grooves 12 are provided on the upper parts of the inner lining plates 4 and the outer lining plates 5, and the two upper grooves 12 have the same size, and the interior of the upper groove 12 and two rollers 11 with the same structure are slidingly arranged with each other, and the inner annular surface of the middle part of the two rollers 11 is fixedly arranged with the outer annular surface of the two long axes 10, and the two long axes 10 are connected to the two ends of the side wall of the second panel 16, and the surface of the long axis 10 away from the roller 11 is movably penetrated and rotatably connected with the surface of one side of the upper rack 65.

[0042] Reference Figure 3 、 Figure 4 、 Figure 7 , and a sliding groove 13 is opened at the lower part of the inner lining plate 4, and a sliding groove 13 is also opened at the lower part of the outer lining plate 5. Although the sliding groove 13 opened at the lower part of the outer lining plate 5 is consistent in height with the sliding groove 13 opened at the lower part of the inner lining plate 4, the length of the sliding groove 13 opened at the lower part of the outer lining plate 5 is only half of the length of the sliding groove 13 opened at the lower part of the inner lining plate 4, and the inner surface of the sliding groove 13 opened at the lower part of the inner lining plate 4 is set to a smooth surface, and is slidably arranged with the short shaft 9 which is also set to a smooth surface, and the short shaft 9 is rotatably connected to the surface of one side of the first panel 15 away from the surface of the outer lining plate 5, and the length of the short shaft 9 is consistent with the width of the upper slide groove 12 and is located close to the transition point of the first panel 15. On the side wall near the second panel 16, and the side wall of the first panel 15 away from the second panel 16, a long axis 10 is rotatably set, and the long axis 10 transferred on the first panel 15 is consistent in structure with the long axis 10 slidingly set inside the upper slide groove 12, and the end of the long axis 10 away from the first panel 15 is movably penetrated and rotatably connected with the fixed horizontal bar 7, and the outer surface of the long axis 10 is set to a smooth surface and is slidably connected to the smooth surface inside the two sliding grooves 13 opened at the lower part of the inner lining plate 4 and the outer lining plate 5, and the sliding groove 13 opened at the lower part of the inner lining plate 4 is located on the upper surface of one side of the cutting mechanism 3 and is also provided with an arc groove 14, and the arc groove 14 can slide and limit the short axis 9.

[0043] Reference Figure 8 , and an arc groove 14 is provided on the upper surface of the middle part of the sliding groove 13 opened at the lower part of the inner lining plate 4, and an arc groove 14 is also provided on the upper surface of the inner cavity of the sliding groove 13 opened at the lower part of the outer lining plate 5 on the side of the gear 61. The two arc grooves 14 have the same structural dimensions, and the arc groove 14 located in the middle of the sliding groove 13 at the lower part of the inner lining plate 4 corresponds exactly to the position of the arc groove 14 opened in the sliding groove 13 at the lower part of the outer lining plate 5 and can be connected to each other, and both arc grooves 14 are set to smooth surfaces and are both clamped with the long shaft 10.

[0044] It should be noted that the electrical cabinet 1 and the cutting mechanism 3 are both existing technologies, and their structural principles will not be described in detail here. The distance between the first panel 15 and the second panel 16 can be changed according to actual needs.

[0045] The first panel 15 and the second panel 16 are staggered with each other and arranged between the two inner lining plates 4 so that they can slide against each other for replacement, and the long shafts 10 arranged on both sides of the second panel 16 can drive the second panel 16 to slide in the upper slide groove 12, and then cooperate with the rollers 11 for assistance, so that the sliding of the second panel 16 is smoother, and the upper slide grooves 12 opened on the upper parts of the inner lining plate 4 and the outer lining plate 5 are connected to each other to ensure that the long shaft 10 passes through the upper slide groove 12 and is connected to the upper rack 65 and drives the upper rack 65 to rotate. The length of the downward slide groove 13 provided at the lower part of the inner lining plate 4 is the same as the length of the upper slide groove 12, but the downward slide groove 13 provided at the lower part of the outer lining plate 5 is only half of the length of the upper slide groove 12, and the short axis 9 provided on the side of one end of the first panel 15 close to the second panel 16 is half of the length of the long axis 10 provided on the side of one end away from the second panel 16. The short axis 9 can only move in the downward slide groove 13 at the lower part of the inner lining plate 4, while the long axis 10 can move in the lower downward slide grooves 13 of both the inner lining plate 4 and the outer lining plate 5.

[0046] The arc groove 14 in the middle of the sliding groove 13 at the bottom of the inner lining plate 4 is connected to the arc groove 14 set in the lower sliding groove 13 at the end of the outer lining plate 5 near the second panel 16, which can ensure that when the short shaft 9 and the long shaft 10 carry the first panel 15 and the second panel 16 to be replaced, the short shaft 9 will not be affected by the arc groove 14 and can directly slide through the sliding groove 13 at the bottom of the inner lining plate 4 to the arc groove 14 at the bottom of the inner lining plate 4 near the end of the cutting mechanism 3 for limitation, while the long shaft 10 slides directly to the middle of the inner lining plate 4, that is, the end of the outer lining plate 5 near the second panel 16, through the sliding groove 13 at the bottom of the inner lining plate 4 and the outer lining plate 5, and the arc groove 14 at the bottom of the outer lining plate 5 is set at the end of the outer lining plate 5, so under the influence of the outer lining plate 5, the long shaft 10 will slide into the arc groove 14 at the bottom of the outer lining plate 5 for limitation, and the first panel 15 and the second panel 16 can be replaced.

[0047] Reference Figure 5 、 Figure 6 、 Figure 7, two reciprocating replacement mechanisms 6 are provided on the side of the two outer lining plates 5 away from the inner lining plate 4, and the two reciprocating replacement mechanisms 6 have the same structure and installation method, and the reciprocating replacement mechanism 6 includes a servo motor 66 fixedly connected to the middle of the outer surface of the outer lining plate 5 away from the inner lining plate 4, and the output end of the servo motor 66 is fixedly connected to the inner ring surface of the gear 61 through a coupling, and the gear 61 is rotatably provided in the middle of the surface of the outer lining plate 5 away from the inner lining plate 4, and the lower part of the gear 61 is meshed with the upper part of the lower rack 62, and two fixing rods 6 are fixedly provided at both ends of the outer surface of the lower rack 62 away from the first panel 15 3. The two fixing rods 63 have the same structure and installation method, and two fixing columns 64 are fixedly provided on the lower part of the two fixing rods 63, and the two fixing columns 64 have the same structure and installation method, and the two fixing columns 64 are movably passed through and rotatably arranged on the side away from the fixing rods 63 and the side of the fixed horizontal bar 7, and are meshed with each other on the upper part of the gear 61 and the lower part of the upper rack 65, and one side surface of the upper rack 65 is slidably provided on the side surface of the upper part of the outer lining plate 5 away from the inner lining plate 4, and both ends of the upper rack 65 and the sliding side surface of the outer lining plate 5 are rotatably connected to the two long shafts 10 transferred to the side of the second panel 16.

[0048] The output end of the servo motor 66 rotates to drive the gear 61 to rotate, thereby driving the lower rack 62 and the upper rack 65 to move relative to each other, so that the lower rack 62 drives the fixed rod 63 and the fixed column 64 to move together, thereby driving the fixed horizontal bar 7 to move synchronously, and the upper rack 65 simultaneously drives the long shaft 10 connected to it to move, thereby driving the second panel 16 to perform linear reciprocating motion in the upper slide groove 12.

[0049] Reference Figure 4 、 Figure 6 Two supporting links 8 are rotatably provided at both ends of the fixed horizontal bar 7 away from the fixed column 64, and the two supporting links 8 have the same structure and installation method. The upper part of the supporting link 8 on the side of the gear 61 is rotatably connected to the short shaft 9, and the upper part of the supporting link 8 on the side away from the gear 61 is rotatably connected to the long shaft 10, and the two ends of the fixed horizontal bar 7 on the side away from the fixed column 64 are fixedly connected to the vertical limit rod 18, and two oblique limit rods 17 are fixed at both ends of the surface of the fixed horizontal bar 7 on one side of the support link 8, and the two oblique limit rods 17 are away from the vertical limit rod 18 and are arranged in the same direction, and the oblique limit rod 17 and the vertical limit rod 18 are arranged on both sides of the lower part of the support link 8, and can limit the support link 8.

[0050] Support links 8 are rotatably set at both ends of the fixed horizontal bar 7, and the upper parts of the two support links 8 are connected to the short axis 9 and the long axis 10 respectively. When the fixed horizontal bar 7 is moved by the fixed column 64, the support links 8 can be driven to move at the same time, and then the first panel 15 can be driven to move, thereby achieving the purpose of replacing with the second panel 16. The support links 8 are connected to the fixed horizontal bar 7, and are also connected to the short axis 9 and the long axis 10. When the long axis 10 slides down to the arc groove 14 to be limited under the action of the outer lining plate 5, the two support links 8 can be in a right angle state, and under the action of the vertical limit rod 18, an oblique angle in the opposite direction of the oblique limit rod 17 will be generated, making it impossible to rotate. The oblique limit rod 17 can also limit the support links 8 downward.

[0051] It should be noted that the servo motor 66 is a prior art, and the device also requires a controller such as a PLC for cooperation, but since they are all prior art, they will not be described in detail here.

[0052] The implementation principle of a cardboard cutting device according to an embodiment of the present application is as follows: when using the device to cut cardboard, by turning on the switch in the electrical cabinet 1, the cutting mechanism 3 and the servo motor 66 are powered on to work, and when the output end of the servo motor 66 rotates, it can drive the gear 61 to rotate, thereby driving the lower rack 62 and the upper rack 65 to move toward the middle, so that the lower rack 62 drives the fixed rod 63 and the fixed column 64 to move together, thereby driving the fixed horizontal bar 7 to move synchronously, and the movement of the fixed horizontal bar 7 can drive the supporting connecting rod 8 to move, thereby driving the long shaft 10 and the short shaft 9 to move in the lower groove 13, and the short shaft 9 and the long shaft 10 both move. When it reaches the lower part of the arc groove 14, the fixed horizontal bar 7 continues to move forward. At this time, the long axis 10 moves into the arc groove 14 under the obstruction of the outer lining plate 5. During the movement, the supporting link 8 pushes the long axis 10 upward under the drive of the fixed horizontal bar 7, and the short axis 9 enters the arc groove 14 through the curvature of the lower part of the arc groove 14 and the thrust of the fixed horizontal bar 7. When the short axis 9 and the long axis 10 enter the arc groove 14, the vertical limit rod 18 will limit the supporting link 8 to prevent the supporting link 8 from moving too far forward and unable to return. At the same time, the second panel 16 will also move to the lower part of the cutting mechanism 3 and exchange with the second panel 16.

[0053] At the same time, the upper rack 65 drives the long shaft 10 connected thereto to move, thereby driving the second panel 16 to perform linear reciprocating motion in the upper slide groove 12 , thereby achieving replacement with the first panel 15 .

[0054] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
