[0042] The bag body to which the present invention applies is Figure 10The same or equivalent bag body 10 shown includes a bag body 100, a bag mouth seat 101, and a cover body 102 connected to the bag mouth seat. The cover body is made of a soft material, and an annular groove 103 is provided on the bag mouth seat 101.

[0043] As Figures 1-5 A cover-pulling and material-extracting device shown includes: a frame 1; a bag body positioning mechanism 2 for positioning the bag body, which is provided with a bag mouth limiting component 20 for limiting the bag mouth seat and preventing the displacement of the bag mouth seat; and a sliding plate 3 provided on the upper side of the bag body positioning mechanism 3, the sliding plate is configured to be horizontally slidable, and a material-extracting component 4 and a cover-pulling component 5 are provided on the sliding plate. Both the material-extracting component 4 and the cover-pulling component 5 are configured to be independently liftable.

[0044] Among them, after the bag mouth seat 101 is limited by the bag mouth limiting component 20, the cover-pulling component 5 is located directly above the bag mouth seat 101. The cover-pulling component 5 grabs the cover body downward and then pulls out the cover body upward. After that, the sliding plate 3 is translated again so that the material-extracting component 4 is translated to directly above the bag mouth seat. The material-extracting component 4 descends and extends into the bag mouth seat for material extraction.

[0045] As Figure 3 Shown, a base plate 6 is provided at the top of the frame 1. The sliding plate 3 is slidably connected to the base plate. A third power 30 for driving the horizontal movement of the sliding plate is provided on the frame 1; a long groove avoidance hole 60 for avoiding the material-extracting component and the cover-pulling component is provided on the base plate 6; a cleaning chamber 7 is provided inside the frame at the position between the sliding plate and the bag body positioning mechanism, and the base plate is installed on the top of the cleaning chamber.

A material extraction pipe 43 is provided on the side of the material extraction cylinder 40. The valve rod is configured to close the material extraction cylinder when descending and open the material extraction cylinder when ascending. That is, when the valve rod descends, the opening at the lower end of the material extraction cylinder is closed and material extraction cannot be performed. When the valve rod ascends, the lower end of the material extraction cylinder opens, enabling the material extraction cylinder to communicate with the material extraction pipe. A fourth power 44 for driving the material extraction cylinder to lift and lower is provided on the slide plate 3.

[0051] As shown Figure 3 and Figure 4 in FIGS. 6 and 7, a cleaning seat 70 is provided inside the cleaning chamber 7. A medium discharge pipe 71 is connected to the cleaning seat. A medium inlet pipe for introducing a cleaning medium into the material extraction cylinder is connected in parallel to the outer end of the material extraction pipe (the medium inlet pipe is omitted in the figure, and the medium finally enters the material extraction cylinder through the material extraction pipe). When the cap pulling assembly 5 moves directly above the bag mouth seat, the material extraction assembly 4 is directly above the cleaning seat, and the material extraction cylinder descends and extends into the cleaning seat, enabling the medium inlet pipe, the material extraction cylinder, the cleaning seat, and the medium discharge pipe to communicate. A sterilization assembly 72 for introducing a sterilization medium into the cleaning chamber is provided on the side of the cleaning chamber 7. A liquid discharge assembly 73 for discharging the residual medium at the bottom of the cleaning chamber is provided at the bottom of the cleaning chamber. Specifically, the sterilization assembly is a plurality of branch pipes communicating with the side of the cleaning chamber, and the sterilization gas (high-temperature water vapor) enters the sterilization chamber through the branch pipes, and the residual water after sterilization is discharged from the liquid discharge assembly.

The specific setting method is as shown Figure 4 in FIG. 8.

[0053] A method for removing the cap and extracting materials, comprising the following steps:

[0054] S1. The bag body is loaded into the bag body positioning mechanism, the bag mouth seat extends into the limiting hole and is limited by the bag mouth limiting component; after the bag body is positioned and before the cap is removed, the sterilization component performs a sterilization operation on the cleaning chamber;

[0055] S2. The cap removing component is directly above the bag mouth seat. The cap removing component moves downward under the action of the fifth power to grab the cap. After the cap removing component grabs the cap, first, hot air is introduced into the central hole of the heating block through the heating component and the diversion pipe, so that the cap is softened by heat and then the cap is removed. The cap removing state is as shown in Figure 7 shown, and the cap removing component moves upward to remove the cap;

[0056] S3. The slide plate moves under the action of the third power, so that the material extracting component moves to directly above the bag mouth seat. Under the action of the fourth power, the lower end of the material extracting cylinder descends and inserts into the bag mouth seat, the valve rod rises to open the material extracting cylinder, and the material extracting pipe performs a material extracting operation. The material extracting state is as shown in Figure 8 shown;

[0057] S4. After the material extraction is completed, the lower end of the material extracting cylinder is closed by the valve rod and then reset upward. The third power drives the slide plate to move, so that the cap removing component translates to directly above the bag mouth seat. The cap removing component moves downward to install the cap back onto the bag mouth seat and then resets. The cap installing state is as shown in Figure 9 shown;

[0058] S5. The bag mouth limiting component releases the limit on the bag mouth seat, and the bag body is taken down;

[0059] After step S5 or when the entire device finishes working, the material extracting component descends and extends into the cleaning seat, so that the medium inlet pipe, the material extracting cylinder, the cleaning seat, and the medium discharge pipe are communicated. Cleaning liquid is introduced into the medium inlet pipe to clean the material extracting cylinder.

[0060] This kind of cap removing and material extracting device can automatically realize cap removing, material extracting, and cap installing operations after the bag body is positioned, greatly improving the efficiency of cap removing and material extracting. At the same time, a sterilization operation is performed on the cleaning chamber before cap removing and material extracting, and the inside of the material extracting component is cleaned, thereby ensuring that the whole process is cleaner and more hygienic.
