[0033] Reference Figures 1 to 7A device for capping a nozzle comprises: a capping mechanism 100, a nozzle bag feeding mechanism 200 and a nozzle cover feeding mechanism 300. The capping mechanism 100 comprises a nozzle bag arranging seat 110, a nozzle cover conveying seat 120, an elastic material blocking structure 130 and a pressing assembly 140. The nozzle bag arranging seat 110 is provided with a nozzle slide 111 extending in the front-to-back direction, the nozzle slide 111 is provided with a nozzle bag feeding end 1111 at the rear end and a nozzle bag delivery end 1112 at the front end, the nozzle cover conveying seat 120 is provided with a nozzle cover slide 121, the nozzle cover slide 121 is provided with a cover input end 1211 at the rear end and a cover output end 1211 at the front end 2. The nozzle cover slide 121 is tilted relative to the horizontal direction, and the cover output end 1212 is lower. The cover output end 1212 is arranged on the upper side of the nozzle slide 111 and opposite to the nozzle slide 111. The elastic material stop structure 130 is arranged at the cover output end 1212. A nozzle passing position 150 is arranged between the cover output end 1212 and the nozzle slide 111, which allows the nozzle to hook the nozzle cover. The pressing assembly 140 is arranged at the front side of the cover output end 1212 of the nozzle cover slide 121 and is used to press the nozzle cover onto the nozzle. The nozzle bag feeding mechanism 200 is used to feed the nozzle bag into the nozzle bag feeding end 1111 of the nozzle slide 111, and the nozzle cover feeding mechanism 300 is used to feed the nozzle cover into the cover input end 1211 of the nozzle cover slide 121.

[0034] When the device is working, the nozzle cover is fed into the nozzle cover slide 121 through the nozzle cover feeding mechanism 300, so that the nozzle covers form a queue in the nozzle cover slide 121, and the nozzle cover at the end of the queue is blocked by the elastic material blocking structure 130. Since the nozzle cover slide 121 is inclined, the cover opening of the nozzle cover can face downward and rearward; when the nozzle bags are fed into the nozzle slide 111 one by one through the nozzle bag feeding mechanism 200, the nozzle bags are slidably arranged on the nozzle slide 111 through the nozzle, and are arranged in the nozzle slide in the form of a queue. The suction nozzle bag is pushed forward in the suction nozzle cover slide 111. When the suction nozzle bag moves forward, when it passes through the suction nozzle passing position 150, the suction nozzle can be inserted into the cover opening of the suction nozzle cover facing downward and hooked with the suction nozzle cover to move forward together. When the suction nozzle bag continues to move forward, it can overcome the elastic force of the elastic material blocking structure 130 and bring the suction nozzle cover out of the suction nozzle cover slide 121. The suction nozzle cover can then lightly cover the suction nozzle. When the suction nozzle and the suction nozzle cover move to the pressing assembly 140, the pressing assembly 140 can press the suction nozzle cover to press it on the suction nozzle, thereby completing the installation of the suction nozzle cover. The above-mentioned device for pressing the suction nozzle cover can automatically load and take away the suction nozzle cover in the suction nozzle cover slide 121 when the suction nozzle bag continues to move forward. After passing through the pressing assembly 140, the suction nozzle cover can be automatically installed in place. The processes of installing the nozzle cover into the nozzle and pressing the nozzle cover onto the nozzle are all realized in the queue pushing of the nozzle bag. The overall structure is simple, and there is no need for a robot with complex movements to grab the cover and install the cover. The installation of the nozzle cover can be completed continuously and efficiently.

[0035] In an embodiment, the nozzle bag feeding mechanism 200 is provided with an insertion position 210 for an external nozzle bag conveyor line to penetrate in the left-right direction. The nozzle bag feeding mechanism 200 includes a nozzle bag pushing assembly 220, a nozzle bag rotating assembly 230 and a nozzle bag pushing assembly 240. The nozzle bag pushing assembly 220 is used to push the nozzle bag on the nozzle bag conveyor line to the nozzle bag rotating assembly 230, the nozzle bag rotating assembly 230 is used to rotate the nozzle bag so that the nozzle of the nozzle bag faces upward, and the nozzle bag pushing assembly 240 is used to push the nozzle bag on the nozzle bag rotating assembly 230 into the nozzle slide 111. When setting up the device of the utility model, the device can be set at the tail of the nozzle welding machine, so that the nozzle welding machine is used to output the nozzle bag conveyor line of the nozzle bag that has completed welding to the outside, and penetrate into the aforementioned conveyor line insertion position 210. After the nozzle bag completes the nozzle welding, the nozzle bag is sent out through the nozzle bag conveyor line with the nozzle facing down. When the nozzle bag is transferred to the position corresponding to the nozzle bag pushing component 220, it can be pushed to the nozzle bag rotating component 230. After the nozzle bag is rotated 180 degrees and the direction is changed by the nozzle bag rotating component 230, the overturned nozzle bag is pushed into the nozzle slide 111 by the nozzle bag pushing component 240. The above structure can conveniently obtain the nozzle bag from the nozzle bag conveyor line and supply it to the nozzle slide 111 after overturning. The structure is simple and easy to implement. It can be imagined that the nozzle bag feeding mechanism 200 is not limited to the above-mentioned implementation method.

The rotating seat 231 is rotatable around the front and rear axis. The rotating seat 231 is respectively provided with nozzle transition grooves 2311 at both ends along the direction perpendicular to the rotation axis. The rotating seat 231 can move to the following position: when the nozzle transition groove 2311 at one end is docked with the nozzle bag feeding end 1111 of the nozzle slide 111, the nozzle transition groove 2311 at the other end is opposite to the nozzle bag pushing assembly 220. The rotating seat 231 can rotate 180 degrees so that the nozzle transition grooves 2311 at both ends can interchange positions. The rotating driver 232 is used to drive the rotating seat 231 to rotate.

[0037] The nozzle bag can be pushed from the nozzle bag conveyor line to the nozzle transition groove 2311 at one end of the rotating seat 231 by the nozzle bag pushing component 220, and then the rotating seat 231 is driven to rotate 180 degrees by the rotating driver 232, so that the nozzle bag flips and reaches a position corresponding to the nozzle slide 111, and then the nozzle bag can be pushed into the nozzle slide 111 by the nozzle bag pushing component 240. The above structure realizes the transfer of the nozzle bag by setting the nozzle transition groove 2311 at both ends of the rotating seat 231, and the structure is simple and easy to implement. In an embodiment, the rotating seat 231 is rotatably arranged on a support seat through a rotating shaft, and the rotating shaft is connected to the rotating driver 232.

If it is necessary to produce nozzle bags that do not require a pressure cover, the rotating seat 231 can be kept in place, and the nozzle bag can be pushed out by the nozzle bag pushing assembly 220 and directly pass through the nozzle transition groove 2311 and enter the coverless nozzle slide 161, so that the nozzle bag can be directly output without a cover. The above structure can determine whether to produce a nozzle bag with a cover by controlling whether the rotating seat 231 is in motion, and the production adjustment is convenient.
