[0048] The screw bottle jam sensor 1-2 alarms when a bottle is jammed in the bottle feeding screw assembly 1, thereby ensuring the safety of the equipment;

[0052] The aluminum cover sensor 4-4 detects whether the container has an aluminum cover after capping;

[0053] The reject box sensor 7-1 alarms when the reject box of the reject device 7 is full, thereby preventing the reject sampling container from being squeezed or exploded due to excessive amount of rejects;

[0054] The maximum discharge sensor 6-2 will alarm when the rear discharge is congested, and the equipment will stop production to prevent the container from being blocked and unable to be placed, resulting in bottle squeezing and bottle explosion.

[0055] The vibrating hopper 2 provides aluminum covers for the rolled cover containers;

[0056] The pre-feed hopper 3 provides an aluminum cover for the vibrating hopper 2;

[0057] The first container taking and placing device 9 can complete the actions of taking the container out from the bottle feeding screw assembly 1, completing the capping, capping detection, secondary capping, and placing the container on the capping device 4;

[0058] The second container taking and placing device 8 can complete the actions of taking the container out from the capping device 4, detecting the aluminum cap, performing secondary capping, and placing the container in a waste rejection box or a discharging mesh belt device 6.

[0059] The working principle of the above device is as follows:

[0060] The first container picking and placing device completes the actions of taking the container out from the bottle feeding screw assembly, completing the capping, capping detection, secondary capping, and placing the container on the capping device;

[0061] The vibrating hopper is equipped with a material unloading and lid hanging device, which can complete the automatic loading of aluminum lids and the hanging of lids on containers;

[0062] The capping device comprises a bottle pressing head assembly, a capping knife assembly and a bottle holder compression and rebound assembly; when the first container picking and placing device places the container on the bottle holder of the bottle holder compression and rebound assembly, the bottle pressing head assembly rotates and presses down to press the aluminum cap and the container tightly, driving the aluminum cap, the container and the bottle holder to rotate, the capping knife holder swings, and the capping knife slowly performs the capping action after approaching the aluminum cap, wrapping the lower edge of the aluminum cap to the lower edge of the bottle mouth, and after the capping is completed, the knife holder retreats, the bottle pressing head is lifted, and the bottle holder stops rotating to drive the container to stop rotating;

[0063] The second container picking and placing device completes the actions of taking the container out of the capping device, detecting the aluminum cap, performing secondary capping, and placing the container in a reject box or a discharging mesh belt device;

[0064] The touch screen control device 5 is an integrated operating device for the electrical program of the whole machine;

[0065] The bottle discharging mesh belt device is a qualified product discharging device;

[0066] The reject device provides a placement location for unqualified products.

[0067] Figure 2 The figure shows a schematic diagram of a fully automatic capping device (taking a batch of five containers as an example, the device of the utility model is not limited to the number of containers in a batch), the bottle feeding screw assembly rotates to separate and fix the containers, stops rotating at a fixed position, and provides a grabbing position for the first container picking and placing device. A sensor is provided before the screw is fixed, which can detect whether there are containers entering the corresponding position in the standard pitch section and count the containers entering the capping device;

[0068] The vibrating hopper transports the aluminum caps in an orderly and unidirectional manner to the unloading channel, and the aluminum caps slide to the cap hanging point through the unloading channel. This device continuously provides aluminum caps for the container;

[0069] The first container picking and placing device takes the container out from the bottle feeding screw assembly, completes the capping through the capping position, and the aluminum cap is hung above the container mouth. Then, the capping sensor is used to detect whether the aluminum cap of the container is hung. If there is a container that has not completed the capping, for example, container No. 2 among containers No. 1, 2, 3, 4, and 5 has not completed the capping, the first container picking and placing device grabs all the containers and places them on the bottle tray of the capping device first, then grabs container No. 2 and returns to the top of the screw, and re-caps the container No. 2. After the capping is completed, the container No. 2 is placed on the capping device;

[0070] The capping device presses and covers the aluminum cap on the container mouth. When the first container picking and placing device places the container on the capping bottle holder, the bottle pressing head rotates and presses down. The bottle pressing head assembly and the bottle holder are both resilient, so the action is flexible and controllable during pressing, and the aluminum cap and the container will not be damaged. When the aluminum cap and the container are pressed and rotated together, the capping knife approaches the container, and then slowly squeezes and covers the lower edge of the aluminum cap to surround the lower edge of the container mouth. The capping knife has resilience, and the capping is flexibly covered, so the lower edge of the aluminum cap will not be cut, and the container will not be damaged. When the capping is completed, the capping knife retreats and disengages, and the bottle pressing head slowly rises, and the container is completely disengaged after the rotation speed is reduced and stopped, and the entire capping work is completed.

[0071] The second container picking and placing device grabs the container from the capping device and detects the status of the aluminum cap through the aluminum cap sensor. If there is no aluminum cap, the second container picking and placing device will transport the unfinished capping container to the waste rejection device, and the remaining containers will be transported to the discharging device. If all are qualified, they will all be transported to the discharging mesh belt device.

[0072] The devices not described in detail above are all prior art and will not be described in detail.
