[0001] The utility model relates to the technical field of food and medicine packaging, in particular to a waste paper collecting device for an isolator and the isolator. Background Art
[0002] Pre-filled inner packaging unpacking machines continuously generate waste during the unpacking process. When existing isolators are in use, waste is stored in the isolator. After it is full, the machine is shut down for cleaning and disinfection. This method of storing waste paper cannot support large-scale production. Alternatively, a transfer port is set on the isolator to transfer waste paper during production. However, if a direct transfer method is used, the transfer port often needs to be set relatively large. At this time, it is difficult to maintain pressure in the isolator, and air outside the isolator may flow back, posing a high risk of contamination. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a waste paper collecting device and separator for a separator which can reduce the size of the waste paper conveying port and reduce the amount of air leakage.

[0028] Example 1
[0029] Figure 1 and Figure 2An embodiment of a waste paper collection device for an isolator of the present invention is shown. The waste paper collection device for an isolator of this embodiment includes a waste paper conveying mechanism 2 arranged in an isolator 1. A waste paper collection box 3 is provided at the bottom of the waste paper conveying mechanism 2, and a waste paper conveying port 4 is provided between the two. The waste paper conveying port 4 is equipped with a movable sealing door 5. The waste paper conveying mechanism 2 is used to convey the waste paper in the isolator 1 downward to the waste paper collection box 3.
[0030] The waste paper collection device for an isolator is configured such that when the isolator 1 is in production mode, the movable sealing door 5 on the waste paper conveying port 4 is opened, and waste paper generated in the isolator 1 is conveyed by the waste paper conveying mechanism 2 through the waste paper conveying port 4 to the waste paper collection box 3 at the bottom for collection; when the isolator 1 needs to enter a sterilization state or the waste paper collection box 3 needs to be replaced, the movable sealing door 5 on the waste paper conveying port 4 is closed to keep the isolator 1 in a sealed state as much as possible and avoid damaging the air pressure in the isolator 1.
[0031] The waste paper collecting device for an isolator conveys waste paper downward through a waste paper conveying mechanism 2. Relative to the free fall of waste paper, the size of the waste paper conveying port 4 can be reduced, thereby reducing air leakage and facilitating maintaining the air pressure in the isolator 1 when the isolator 1 is in a working state. Furthermore, when the isolator 1 needs to enter a sterilization state or the waste paper collection box 3 needs to be replaced, the waste paper conveying port 4 can seal the isolator 1 by closing a movable sealing door 5, thereby preventing external air from flowing back into the isolator 1 and contaminating the isolator 1.
[0032] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the waste paper conveying mechanism 2 includes a conveying chamber 6, within which is disposed a guide plate 7. A conveying roller assembly 8 is located below the guide output end of the guide plate 7. The waste paper conveying port 4 is located below the conveying roller assembly 8. After waste paper from the separator 1 enters the conveying chamber 6, it is guided by the guide plate 7 and then enters the conveying roller assembly 8. The conveying roller assembly 8 then drives the waste paper into the waste paper conveying port 4.
[0033] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the conveyor roller assembly 8 includes a first roller 81 and a second roller 82. The central axis of the first roller 81 is fixed, while the central axis of the second roller 82 can swing, allowing the second roller 82 to move closer to or away from the first roller 81. A waste paper conveying channel 83 is provided between the first roller 81 and the second roller 82. The waste paper conveying channel 83 is located below the guide output end of the guide plate 7 and above the waste paper conveying port 4. Before the waste paper is introduced, the second roller 82 moves away from the first roller 81, allowing the waste paper to enter the waste paper conveying channel 83 between the first roller 81 and the second roller 82 under the guidance of the guide plate 7. The second roller 82 then swings closer to the first roller 81, driving the waste paper downward.
[0034] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, a paper pressing mechanism 9 is provided on the guide plate 7, and the paper pressing mechanism 9 is used to flatten the waste paper. The paper pressing mechanism 9 flattens the waste paper on the guide plate 7, which is beneficial to the subsequent guided transportation.
[0035] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the paper pressing mechanism 9 includes a rotating shaft 91 and a flattening rod 92. The rotating shaft 91 is disposed above the guide plate 7, with a clearance between the rotating shaft 91 and the guide plate 7 for waste paper to pass through. One end of the flattening rod 92 is disposed on the rotating shaft 91. When waste paper reaches below the flattening rod 92, the rotating shaft 91 rotates, driving the flattening rod 92 toward the waste paper, flattening it as it falls. After the waste paper is conveyed, the flattening rod 92 returns to its original position and waits for the next operation.
[0036] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the other end of the flattening rod 92 is provided with a paper stop guide 93, which is used to guide the flattened waste paper into the waste paper conveying channel 83. After the flattening rod 92 flattens the waste paper, the paper stop guide 93 guides the waste paper into the waste paper conveying channel 83, facilitating the conveying roller assembly 8 to drive the waste paper.
[0037] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, a paper stopper 10 is further provided within the conveying chamber 6. The guide plate 7 and the paper stopper 10 are respectively located on either side above the second roller 82. The paper stopper 10 prevents waste paper from falling outside the conveying roller assembly 8 when it falls onto the guide plate 7, thereby facilitating its entry into the waste paper conveying passage 83 for conveyance.
[0038] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, sealing grooves 11 are provided on both sides of the waste paper conveyor port 4. Inflatable sealing rings 12 are located within the sealing grooves 11. A movable sealing door 5 is movably mounted on top of the sealing grooves 11. When the movable sealing door 5 is closed, the inflatable sealing rings 12 form a seal with the sealing grooves 11 on both sides of the waste paper conveyor port 4, further improving the sealing performance of the waste paper conveyor port 4.
[0039] Furthermore, if Figure 2 As shown, in this embodiment, a negative pressure chamber 13 is provided within the waste paper collection box 3. The top of the negative pressure chamber 13 is connected to the waste paper delivery port 4, and the bottom of the negative pressure chamber 13 has an opening 14. Furthermore, exhaust ports 15 are provided on the sides of the negative pressure chamber 13. When the waste paper delivery port 4 is open, the exhaust ports 15 on both sides of the negative pressure chamber 13 draw air from above and below the waste paper delivery port 4, further reducing the risk of external air backflowing into the isolator 1.
[0040] Example 2
[0041] Figure 3 and Figure 4 An embodiment of the isolator 1 of the present invention is shown. The isolator 1 of this embodiment includes an isolator cavity 16. A packaging material conveyor line 17 is provided in the isolator cavity 16. A robot film tearing station 18, a heating station 19, a liner paper removal station 20 and the above-mentioned waste paper collection device are provided on one side of the packaging material conveyor line 17.
[0042] In the isolator 1, the packaging material conveying line 17 conveys the packaging material, the heating station 19 heats the packaging material, the robot film tearing station 18 tears off the box cover paper and throws it into the waste paper collection device for collection, and the lining paper taking station 20 grabs the inner lining paper and throws it into the waste paper collection device for collection, completing the unpacking. Since the waste paper collection device has the above advantages, the isolator 1 including the waste paper collection device also has the above advantages.
