DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Embodiment:
[0026] Referring to Figures 1-4 , a precise punching device for plastic packaging bags disclosed by the present invention includes a chassis 1 and a mounting table 2 fixedly connected to the upper end thereof. The upper end of the mounting table 2 is fixedly connected with a mounting frame 3, and a punching head 5 is provided on the inner top wall of the mounting frame 3;
[0027] A moving table 7 is provided below the punching head 5, two clamping plates 6 are provided above the moving table 7, and a clamping mechanism 9 is provided below the clamping plates 6;
[0028] The clamping mechanism 9 includes a moving plate 901 and two springs 902. The moving plate 901 is arranged between the side walls of the moving table 7. The clamping plate 6 and the moving plate 901 are connected by two connecting slide bars 903. The two springs 902 are fixedly connected to the upper end of the moving plate 901, and the upper ends of the two springs 902 are fixedly connected to the inner top wall of the moving table 7;
[0029] A pusher is provided below the moving plate 901 for pushing the moving plate 901 upward.
[0030] In this embodiment, when punching the packaging bag, the moving plate 901 moves upward, the spring 902 is in a compressed state, the connecting slide bar 903 pushes the clamping plate 6 upward, the clamping plate 6 moves upward away from the upper end of the moving table 7, the packaging bag is placed on the moving table 7, the moving plate 901 is released, and the spring 902 pushes the moving plate 901 downward due to its own elastic recovery, and the clamping plate 6 moves downward, so as to clamp the packaging bag and prevent the position of the packaging bag from shifting during punching, affecting the punching position.
[0031] Further, for details, please refer to Figure 4 The pusher includes a pushing block 11, and the pushing block 11 is rotatably connected to the lower part of the moving plate 901 through a connecting member.
[0032] In this embodiment, the shape of the pushing block 11 is similar to a water droplet or an ellipse, with a relatively protruding end. When the longer end rotates to the upper part, the longer end will push the moving plate 901 upward. When the shorter end of the pushing block 11 rotates to the upper side, it does not contact the moving plate 901. Due to the elastic recovery of the spring 902, the moving plate 901 will drive the clamping plate 6 downward.
[0033] Further, for details, please refer to Figure 1 The connecting member includes a rotating rod 10. The rotating rod 10 is rotatably connected between the side walls of the mounting table 2. The pushing block 11 is fixedly connected to the circumferential side of the rotating rod 10. One side of the mounting table 2 is fixedly connected with a rotating motor 12, and the output end of the rotating motor 12 is fixed to one end of the rotating rod 10.
[0034] In this embodiment, the output end of the rotating motor 12 drives the rotating rod 10 to rotate, the rotating rod 10 drives the pushing block 11 to rotate. When the pushing block 11 rotates to the longer end, the pushing block 11 pushes the moving plate 901 upward, the spring 902 is in a compressed state, and the clamping plate 6 moves upward. When the pushing block 11 rotates to the shorter end, the pushing block 11 does not contact the moving plate 901, and the spring 902 pulls the clamping plate 6 downward due to its own recovery to clamp the plastic packaging bag.
[0035] Further, for details, please refer to Figure 2 A chute 801 is opened at the upper end of the mounting table 2. The moving table 7 is slidably connected to the chute 801 through a slider 804. A moving mechanism 8 is provided between the slider 804 and the chute 801 for the movement of the slider 804.
[0036] In this embodiment, the mobile station 7 slides in the chute 801 through the slider 804. The slider 804 drives the mobile station 7 to leave the lower part of the mounting bracket 3 or enter the lower part of the mounting bracket 3, which facilitates the feeding of plastic packaging bags.
[0037] Furthermore, for details, please refer to Figure 3 , the moving mechanism 8 includes a lead screw 802 and a driving motor 805. The lead screw 802 is rotatably connected between the side walls of the chute 801. The slider 804 is threadedly connected to the circumferential side of the lead screw 802 through a lead screw nut. The driving motor 805 is fixedly connected to one side of the mounting table 2, and the output end of the driving motor 805 is fixed to the end of the lead screw 802.
[0038] In this embodiment, after the punching of the packaging bag is completed, the driving motor 805 is started. The output end of the driving motor 805 drives the lead screw 802 to rotate. The slider 804 moves on the surface of the lead screw 802. The slider 804 drives the mobile station 7 to move. The mobile station 7 drives the packaging bag to leave the lower part of the mounting bracket 3, removes the punched plastic packaging bag, and installs a new packaging bag. The output end of the driving motor 805 rotates in the reverse direction, the lead screw 802 rotates in the reverse direction, and the mobile station 7 returns to the lower part of the punching head 5 to continue the next punching operation. Preferably, the driving motor 805 is a forward and reverse rotation motor.
[0039] Furthermore, for details, please refer to Figure 1 , two limiting rods 803 are fixedly connected between the side walls of the chute 801. The slider 804 is slidably connected to the circumferential sides of the two limiting rods 803.
[0040] In this embodiment, the slider 804 always moves on the surface of the limiting rod 803, which can make the movement of the mobile station 7 more stable and prevent the mobile station 7 from shaking during movement.
[0041] Furthermore, for details, please refer to Figure 2 , a cylinder 4 is fixedly connected to the upper end of the mounting bracket 3, and the piston rod of the cylinder 4 movably penetrates the inner top wall of the mounting bracket 3 and is fixed to the punching head 5.
[0042] In this embodiment, the cylinder 4 is started. The piston rod of the cylinder 4 pushes the punching head 5 to move downward, and the punching head 5 can perform punching operations on plastic packaging bags.
[0043] The implementation principle of the above embodiments is as follows: When punching the packaging bag, start the rotation motor 12. The output end of the rotation motor 12 drives the rotation rod 10 to rotate. The rotation rod 10 drives the push block 11 to rotate. When the push block 11 rotates to its longer end, the push block 11 pushes the moving plate 901 upward, and the spring 902 is in a compressed state. The moving plate 901 moves upward, and the connecting slide rod 903 pushes the clamping plate 6 upward. The clamping plate 6 moves upward away from the upper end of the moving table 7. Place the packaging bag on the moving table 7, release the moving plate 901, and the spring 902 pushes the moving plate 901 downward due to its own elastic recovery. The clamping plate 6 moves downward to clamp the packaging bag. Start the driving motor 805. The output end of the driving motor 805 drives the lead screw 802 to rotate. The slider 804 moves on the surface of the lead screw 802. The slider 804 drives the moving table 7 to move. The moving table 7 drives the packaging bag to reach below the punching head 5 for punching operations, preventing the position of the packaging bag from shifting during punching and affecting the punching position.
[0044] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0045] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly.
