[0002] In edge sealing packaging bag, some packaging bags are used to contain content with air permeation demand, such as used to contain coffee beans, since coffee beans after roasting will release gas and need to be discharged from packaging bag in time after packaging, at this time, air valve with one-way air permeation needs to be set on packaging bag, so that excess gas in packaging bag can be released in time while ensuring that content is relatively isolated from the outside. Currently, packaging bag with air valve is sealed and connected on packaging bag by heat sealing packaging. Since air valve is small and flat, and packaging bag needs to be laid flat during processing, otherwise, heat sealing packaging will be uneven, which will affect sealing, so most air valve processing equipment adopts simple heat sealing packaging structure, and there is no air valve conveying device, air valve needs to be placed manually at processing position, and then packaging bag is placed to process air valve, so processing efficiency is low.

[0005] Specifically, the air valve feeding device is a vertical chute, the bottom of the vertical chute is a discharge port, and the air valves are vertically stacked in the vertical chute and can slide downward to the bottom along the vertical chute under the action of gravity.

[0006] Specifically, the pushing track comprises a sliding groove part and a limiting clamping part, the limiting clamping part is arranged above the sliding groove part, and the limiting clamping part is provided with an opening at the first end and the end of the pushing track, respectively corresponding to the discharge port of the air valve feeding device and the hot head.

[0007] Specifically, the limiting clamping part is provided with a smooth transition slope at the opening at the end.

[0008] Specific, push material track end outside is provided with packaging bag support platform, the support surface of packaging bag support platform is flush with the upper end surface of the sliding groove part of push material track end.

[0009] The utility model discloses the beneficial effect lies in: through adopt the air valve feeding device of ventilation of vertical setting cooperation push material track, realize the automatic push of air valve and supply material, and in the air valve processing process will not cause the influence to packaging bag;With the transition inclined plane of cooperation in the push track end opening place setting and the packaging bag support platform of push material track end outside setting, can further improve the flat degree of packaging bag in the air valve processing process, reduce the rate of defective products.

[0011] BRIEF DESCRIPTION OF DRAWINGS Fig. 2 It is the side sectional structure drawing of air valve feeding device and push material track, hot press head of example. DETAILED DESCRIPTION

[0012] Example 1, refer to Figs. 1-2 An automatic valve presser for packaging bag air valve processing, including air valve feeding device 1, push material mechanism 2 and hot press head 3, push material mechanism 2 includes push material track 21, push material rod 22 and push material drive mechanism 23, the lower end of air valve feeding device 1 is provided with the discharge port and is connected with the first end of push material track 21, and the end of push material track 21 is aligned with hot press head 3, and hot press head 3 is driven and connected by vertical drive mechanism 31;The lower end of push material track 21 is provided with support component 4.

[0013] In the embodiment, the air valve feeding device 1 is used to store the air valve and make the air valve fall into the first end of the pushing track 21 from the discharge port of the lower end, the pushing driving mechanism 23 is used to drive the pushing rod 22 to push the air valve along the pushing track 21 from the first end to the last end, and after the air valve reaches the last end of the pushing track 21, the packaging bag is only needed to be placed on the air valve and aligned, and then the vertical driving mechanism 31 is controlled to drive the hot pressing head 3 to move downward to perform hot plastic packaging on the packaging bag and the air valve, so that the packaging bag and the air valve are sealed and connected, and the processing of the air valve is completed. The supporting component 4 arranged below the last end of the pushing track 21 can provide effective support for the hot pressing processing of the air valve, and ensure the quality of the hot pressing packaging. The air valve feeding device 1 is a vertical chute, the bottom of the vertical chute is the discharge port, and the air valves are vertically stacked in the vertical chute and can slide downward to the bottom along the vertical chute under the action of gravity. The pushing track 21 includes a sliding groove part 211 and a limiting clamping part 212, and the limiting clamping part 212 is arranged above the sliding groove part 211. The air valve can slide forward in the sliding groove part 211 to the last end of the pushing track 21, the limiting clamping part 212 can limit the movement of the air valve, so that the air valve is prevented from separating from the pushing track 211, and the limiting clamping part 212 is provided with openings at the first end and the last end of the pushing track 21, which correspond to the discharge port of the air valve feeding device 1 and the hot pressing head 3 respectively.

[0014] In addition, in order to avoid that the packaging bag is clamped by the limiting clamping part 212 when the packaging bag is covered on the air valve for hot pressing processing, so that the packaging bag is deformed and affects the sealed connection with the air valve, the limiting clamping part 212 is provided with a smooth transition inclined surface 213 at the opening at the last end. Further, the packaging bag supporting table 5 is arranged outside the last end of the pushing track 21, the supporting surface of the packaging bag supporting table 5 is flush with the upper end surface of the sliding groove part 211 of the last end of the pushing track 21, and the packaging bag supporting table 5 can support the packaging bag during the processing of the air valve, and further improve the hot pressing sealing effect of the packaging bag and the air valve.

[0015] Of course, the above is only the preferred embodiment of the present application, and does not limit the use range of the present application, so that any equivalent change on the principle of the present application should be included in the protection scope of the present application.
