It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1
[0020] See also Figures 1 to 5The utility model provides a technical solution: a cutting device for processing a packaging box, comprising: a bracket 1, a cutting knife 5 and a workbench 18 are arranged on the surface of the bracket 1, a belt transmission mechanism 2 and a servo motor 17 are arranged on the surface of the bracket 1, the servo motor 17 drives the driving wheel of the belt transmission mechanism 2 to rotate, a packaging box raw material 3 is arranged on the top of the belt transmission mechanism 2, a guide rail 4 is fixed on the surface of the bracket 1, a slider 7 is slidably connected in the guide rail 4, a sleeve 9 is fixed at the bottom end of the slider 7, a pull rod 13 is movably inserted in the sleeve 9, and a pressure block 1 is fixed at the bottom end of the pull rod 13 4. A pressing block 14 is arranged above the packaging box raw material 3. An operation panel 6 is arranged on the surface of the bracket 1. Two buttons are arranged on the surface of the operation panel 6. A traction electromagnet 8 is fixed in the guide rail 4. The on and off of the traction electromagnet 8 is controlled by one of the buttons of the operation panel 6. A battery 10 and a lifting electromagnet 11 are arranged in the sleeve 9. The battery 10 supplies power to the lifting electromagnet 11, and the on and off of the lifting electromagnet 11 is controlled by another button of the operation panel 6. A spring 12 is fixed to the bottom end of the lifting electromagnet 11, and the other end of the spring 12 is fixed to the surface of the pull rod 13.
[0021] In actual use, the packaging box raw material 3 is first placed on the top of the belt transmission mechanism 2, and the end of the packaging box raw material 3 close to the workbench 18 is flush with the end of the belt transmission mechanism 2 close to the workbench 18. Then the staff presses the button on the operation panel 6 to operate the traction electromagnet 8, so that the traction electromagnet 8 is energized to generate suction on the metal slider 7, so that one end of the slider 7 is against the surface of the traction electromagnet 8. Then the staff presses the button on the operation panel 6 to control the lifting electromagnet 11, so that the battery 10 stops supplying power to the lifting electromagnet 11, and the spring 12 generates a thrust on the pull rod 13, so that the bottom end of the pull rod 13 extends out of the sleeve 9, and the pull rod 13 moves to The pressing block 14 also moves downward, and finally, under the action of the weight of the pressing block 14 itself and the thrust transmitted to the pressing block 14 by the spring 12 through the pull rod 13, the pressing block 14 is pressed tightly above the packaging box raw material 3, which increases the friction between the packaging box raw material 3 and the conveyor belt of the belt transmission mechanism 2. Then the staff presses the button of the operation panel 6 to control the traction electromagnet 8 and controls the servo motor 17 to start up at the same time. The traction electromagnet 8 is powered off so that the suction force of the traction electromagnet 8 on the slider 7 disappears. After the servo motor 17 is turned on, it will automatically shut down after the transmission shaft of the servo motor 17 rotates a predetermined number of times. When the servo motor 17 rotates, the belt The pulley of the belt transmission mechanism 2 drives the conveyor belt of the belt transmission mechanism 2 to operate. The operation of the conveyor belt of the belt transmission mechanism 2 enables the packaging box raw material 3 to be sent to the workbench 18. Because the number of turns of the transmission shaft of the servo motor 17 will automatically shut down after rotating to a predetermined number of turns, the amount of packaging box raw material 3 sent to the workbench 18 at a single time is fixed. By modifying the predetermined rotation speed of the servo motor 17 when it is turned on once, the single cutting length of the packaging box raw material 3 can be set. After completing the single conveying of the packaging box raw material 3, the pressing block 14 is pressed tightly on one end of the packaging box raw material 3 at the cutting knife 5, and the staff only needs to manually move the packaging box raw material 3 at the other end of the cutting knife 5 The packaging box raw material 3 can be positioned by partial compression, and then the cutting knife 5 arranged on the surface of the rotating bracket 1 can be made to cut through the surface of the packaging box raw material 3 to complete one cutting of the packaging box raw material 3. Then the staff presses the two buttons on the operation panel 6 at the same time, and the lifting electromagnet 11 generates suction on the pull rod 13, so that the pressing block 14 rises and leaves the top of the packaging box raw material 3, and the traction electromagnet 8 generates suction on the slider 7, so that one end of the slider 7 is again against the surface of the traction electromagnet 8. By repeating the above steps, multiple cuttings can be carried out quickly, and the cutting accuracy of the packaging box raw material can be accurately controlled.
[0022] Embodiment 2
[0023] On the basis of Example 1, in order to prevent the excessive friction between the slider 7 and the guide rail 4, which causes the pressure block 14 to generate excessive reverse friction on the packaging box raw material 3, wheel axles 15 are fixed at both ends of the slider 7, and a rotating wheel 16 is rotatably connected to the axis of the wheel axle 15, and the rotating wheel 16 is rollingly connected in the guide rail 4.
[0024] When the pressing block 14 is pressed tightly on the top of the packaging box raw material 3, the friction between the packaging box raw material 3 and the belt transmission mechanism 2 is increased. Therefore, when the conveyor belt of the belt transmission mechanism 2 is running, the packaging box raw material 3 will follow the belt transmission mechanism 2 more accurately under a greater friction force. However, in the initial stage of the packaging box raw material 3 following the movement of the belt transmission mechanism 2, when the packaging box raw material 3 is in the acceleration stage, friction will also be generated between the pressing block 14 and the packaging box raw material 3, and the friction force of the pressing block 14 on the packaging box raw material 3 is opposite to the friction force of the conveyor belt of the belt transmission mechanism 2 on the packaging box raw material 3. Therefore, when the friction force of the pressing block 14 on the packaging box raw material 3 is greater than the friction force of the conveyor belt of the belt transmission mechanism 2 on the belt transmission mechanism 2, it will cause the packaging box raw material 3 to move on the belt transmission mechanism 2. The surface of the mechanism 2 is slippery, so the friction of the pressing block 14 on the packaging box raw material 3 should be minimized. On the one hand, this can be achieved by making the bottom end of the pressing block 14 as smooth as possible. On the other hand, it can also be achieved by making the pressing block 14 move synchronously with the packaging box raw material 3 as much as possible. In order to achieve this goal, it is necessary to minimize the force on the pressing block 14 that is opposite to the movement direction of the packaging box raw material 3. This force is mainly the friction of the track of the guide rail 4 on the slider 7. Therefore, the slider 7 is made smaller so that the slider 7 does not directly contact the track of the guide rail 4. Instead, two sets of wheel axles 15 are fixed at both ends of the guide rail 4, and a rotating wheel 16 is rotatably connected on the wheel axle 15 to make the rotating wheel 16 contact the track of the guide rail 4. In this way, the sliding friction can be converted into rolling friction, thereby greatly reducing the friction.
[0025] In actual use, the packaging box raw material 3 is first placed on the top of the belt transmission mechanism 2, and the end of the packaging box raw material 3 close to the workbench 18 is flush with the end of the belt transmission mechanism 2 close to the workbench 18. Then the staff presses the button on the operation panel 6 to operate the traction electromagnet 8, so that the traction electromagnet 8 is energized to generate suction on the metal slider 7, so that one end of the slider 7 is against the surface of the traction electromagnet 8. Then the staff presses the button on the operation panel 6 to control the lifting electromagnet 11, so that the battery 10 stops supplying power to the lifting electromagnet 11, and the spring 12 generates a thrust on the pull rod 13, so that the bottom end of the pull rod 13 extends out of the sleeve 9, and the pull rod 13 moves to The pressing block 14 also moves downward, and finally, under the action of the weight of the pressing block 14 itself and the thrust transmitted to the pressing block 14 by the spring 12 through the pull rod 13, the pressing block 14 is pressed tightly above the packaging box raw material 3, which increases the friction between the packaging box raw material 3 and the conveyor belt of the belt transmission mechanism 2. Then the staff presses the button of the operation panel 6 to control the traction electromagnet 8 and controls the servo motor 17 to start up at the same time. The traction electromagnet 8 is powered off so that the suction force of the traction electromagnet 8 on the slider 7 disappears. After the servo motor 17 is turned on, it will automatically shut down after the transmission shaft of the servo motor 17 rotates a predetermined number of times. When the servo motor 17 rotates, the belt The pulley of the belt transmission mechanism 2 drives the conveyor belt of the belt transmission mechanism 2 to operate. The operation of the conveyor belt of the belt transmission mechanism 2 enables the packaging box raw material 3 to be sent to the workbench 18. Because the number of turns of the transmission shaft of the servo motor 17 will automatically shut down after rotating to a predetermined number of turns, the amount of packaging box raw material 3 sent to the workbench 18 at a single time is fixed. By modifying the predetermined rotation speed of the servo motor 17 when it is turned on once, the single cutting length of the packaging box raw material 3 can be set. After completing the single conveying of the packaging box raw material 3, the pressing block 14 is pressed tightly on one end of the packaging box raw material 3 at the cutting knife 5, and the staff only needs to manually move the packaging box raw material 3 at the other end of the cutting knife 5 The packaging box raw material 3 can be positioned by partial compression, and then the cutting knife 5 set on the surface of the rotating bracket 1 is made to cut through the surface of the packaging box raw material 3, so that the packaging box raw material 3 can be cut once. Then the staff presses two buttons on the operation panel 6 at the same time, and the lifting electromagnet 11 generates suction force on the pull rod 13, so that the pressing block 14 rises and leaves the top of the packaging box raw material 3, and the traction electromagnet 8 generates suction force on the slider 7, so that one end of the slider 7 is against the surface of the traction electromagnet 8 again. Repeating the above steps, multiple cuttings can be quickly performed, and the cutting accuracy of the packaging box raw material can be accurately controlled.When the pressing block 14 is pressed tightly on the top of the packaging box raw material 3, the friction between the packaging box raw material 3 and the belt transmission mechanism 2 is increased. Therefore, when the conveyor belt of the belt transmission mechanism 2 is running, the packaging box raw material 3 will follow the belt transmission mechanism 2 more accurately under a greater friction force. However, in the initial stage of the packaging box raw material 3 following the movement of the belt transmission mechanism 2, when the packaging box raw material 3 is in the acceleration stage, friction will also be generated between the pressing block 14 and the packaging box raw material 3, and the friction force of the pressing block 14 on the packaging box raw material 3 is opposite to the friction force of the conveyor belt of the belt transmission mechanism 2 on the packaging box raw material 3. Therefore, when the friction force of the pressing block 14 on the packaging box raw material 3 is greater than the friction force of the conveyor belt of the belt transmission mechanism 2 on the belt transmission mechanism 2, it will cause the packaging box raw material 3 to move on the belt transmission mechanism 2. The surface of the mechanism 2 is slippery, so the friction between the pressing block 14 and the packaging box raw material 3 should be reduced as much as possible. This can be achieved by making the bottom of the pressing block 14 as smooth as possible, and by making the pressing block 14 move synchronously with the packaging box raw material 3 as much as possible. In order to achieve this goal, the force on the pressing block 14 in the opposite direction of the movement of the packaging box raw material 3 should be reduced as much as possible. This force is mainly the friction between the track of the guide rail 4 and the slider 7. Therefore, the slider 7 is made smaller so that the slider 7 does not directly contact the track of the guide rail 4. Instead, two sets of axles 15 are fixed at both ends of the guide rail 4, and a rotating wheel 16 is rotatably connected on the axle 15 so that the rotating wheel 16 contacts the track of the guide rail 4. In this way, the sliding friction can be changed into rolling friction, thereby greatly reducing the friction. ;
