Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

As shown in fig. 1 to 5, the present invention discloses a punching device for packaging bag, which comprises a punching base 1, a punching needle 2 and a punching driving device 3; wherein the punching seat 1 is provided with a punching channel 11 which penetrates up and down; the punching needle 2 can move up and down and penetrates through the punching channel 11; the punching driving device is connected with the punching needle 2 and drives the punching needle 2 to move up and down. According to the invention, when the punching driving device drives the punching needle 2 to move downwards, the outer wall of the punching needle 2 and the inner wall of the punching channel 11 are matched to form a cutter so as to punch the packaging bag.

As shown in fig. 4, the punching seat 1 may be provided with a material passing channel 12 penetrating left and right, the material passing channel 12 is communicated with the punching channel 11, and the material passing channel 12 divides the punching channel 11 into an upper punching hole 111 and a lower punching hole 112; the material passing channel 12 of the punching seat 1 is used for allowing the packaging bag to pass through, and the outer wall of the punching needle 2 is matched with the inner wall of the lower punching hole 112 of the punching channel 11 to form a cutter for punching the packaging bag.

As shown in fig. 5, a blowing channel 21 is formed inside the punching needle 2, an inlet 211 of the blowing channel 21 is used for connecting an air source, and an outlet 212 of the blowing channel 21 is arranged on an end surface of the lower end of the punching needle 2; after the punching needle 2 moves downwards to enable the punching needle 2 to punch the bag, the air source connected to the inlet 211 of the blowing channel 21 supplies air to the blowing channel 21, so that the outlet 212 of the blowing channel 21 outputs air flow outwards, and the air flow output from the outlet 212 of the blowing channel 21 blows punching waste of the bag, thereby preventing the punching waste from being adhered to the punching needle 2, further enabling the packaging bag punching device to continuously and effectively punch holes, and improving the production efficiency.

As shown in fig. 2 and 5, the outer peripheral surface of the bottom end of the punching needle 2 is a tapered conical surface from top to bottom, so that when the punching needle 2 finishes punching a bag and then moves upwards, the punching needle 2 is more easily separated from punching waste of a packaging bag, and the punching waste is prevented from being adhered to the punching needle 2.

With reference to fig. 1 and 2, the punching driving device is a punching cylinder 3, and the punching cylinder 3 drives the punching needle 2 to move up and down; this cylinder 3 that punches a hole cooperates in punching seat 1 top, and the cylinder body 31 accessible support rod 4 of cylinder 3 that punches a hole links to each other with punching seat 1 and cooperates cylinder 3 that punches a hole in punching seat 1 top, and the piston rod 32 of cylinder 3 that punches a hole is flexible along the upper and lower direction and the piston rod 32 of cylinder 3 that punches a hole links to each other with punching needle 2, just drives punching needle 2 and reciprocates when the piston rod 32 of cylinder 3 that punches a hole is flexible from top to bottom.
