The invention relates to the field of plastic bag manufacturing, in particular to a plastic bag air hole forming device which comprises a hole forming device, a conveying device and a machine frame. The hole forming device is located above the conveying device. The hole forming device comprises a hole forming wheel, a gear set and a hole forming motor. The hole forming wheel is in the shape of a disc. Convex blocks are arranged on the circumferential wall of the hole forming wheel and used for forming holes in plastic bags. The hole forming wheel is connected with the hole forming motor through the gear set. The conveying device comprises a conveying belt, a driving wheel and a conveying motor. The conveying belt is provided with through holes evenly. The distance between every two adjacent through holes is one quarter the outer circumference of the hole forming wheel. The portion, under the hole forming wheel, of the machine frame is provided with a penetrating hole. The shape of the penetrating hole is matched with that of the driving wheel. The portion, under the penetrating hole, of the machine frame is provided with a fragment collecting box. When the plastic bag air hole forming device is used for forming holes, linear motion is transformed into circular motion, and therefore energy loss produced in the hole forming process is reduced.
Description
technical field [0001] The invention relates to the field of plastic bag manufacturing, in particular to a plastic bag air hole opening device. Background technique [0002] When shopping in the supermarket, some customers suddenly decide not to buy vegetables and fruits, and then discard the vegetables and fruits somewhere in the supermarket. The temperature in the supermarket is high. If the staff does not find out in time, the fruits and vegetables may be destroyed. Rotten, so supermarkets generally use plastic bags with ventilation holes. In addition, some citizens do not eat vegetables and fruits immediately when they buy them home, and plastic bags with holes are also good for storage. In the process of punching plastic bags, the existing ventilation hole opening equipment adopts the mode of linear motion to work in the working process, and its inertia is relatively large, and the energy loss is also relatively large. Contents of the invention [0003] Aiming at th...
