[0050] At the same time, it should be noted that during the production of PVC rubber gloves, various pollutants may exist in the air, such as dust, particulate matter, volatile organic compounds (VOCs) and the like. These pollutants can have a negative impact on the quality and hygiene performance of the gloves, and can also pose a risk to the health and safety of production workers.

[0051] It should also be noted that in the embodiments of the present application, the position of the motor, the connection of the motor, and how to electrically connect are involved. Whether it is an adaptive change to the motor or the use of a motor that does not require an external power supply lamp, it is a routine use for those skilled in the art.

[0054] It should be noted that in the embodiment of the present application, the air outlet pipe 4 and the mounting pipe 5 are slidingly connected, more accurately, the air outlet pipe 4 can be separated from the mounting pipe 5 under the action of the magnetic control mechanism 9, so that when the impurities in the filter structure of the present application are too much, the air supply to the PVC rubber glove production equipment is stopped. At this time, the staff can stop production, and in actual production, the air outlet pipe 4 and the PVC rubber glove production equipment can be improved so that the PVC rubber glove production equipment can stop working when the air outlet pipe 4 is separated from the mounting pipe 5. This is a conventional technical means that can be realized by those skilled in the art.

[0055] In the embodiment of the present application, a sealing capsule 22 is provided at the connection between the mounting pipe 5 and the air outlet pipe 4. In other embodiments, other sealing separation structures can be provided, such as a telescopic sleeve, which is also a preferred embodiment of the present application.

[0056] The sealing air bag is provided because the air outlet pipe 4 must be movably connected to the mounting pipe 5 when the magnetic control mechanism 9 drives the casing 2 to move laterally, so as to ensure the normal filtering effect of the filter structure. At the same time, the sealing air bag can also play a good sealing effect on the air outlet pipe 4 and the mounting pipe 5 when the filter structure of the present application is working normally.

[0057] Referring to Figure 4 and Figure 5 , the first filter assembly 6 is located in the casing 2 and is arranged close to the air inlet pipe 3. The first filter assembly 6 is used for preliminarily filtering the air to be filtered.

[0058] The first filter assembly 6 comprises a centrifugal separation box 61 and a first collection box 62. The centrifugal separation box 61 is fixedly connected to the inner side wall of the casing 2. A centrifugal motor 10 is fixedly connected in the centrifugal separation box 61.

[0059] The first filter assembly 6 is arranged as a combination of the centrifugal separation box 61 and the first collection box 62, so that the large particles in the air passing through the first filter assembly 6 can be effectively centrifuged by the centrifugal fan blade 11 and enter the first collection box 62, thereby realizing the preliminary filtration of the large particles by the first filter assembly 6.

[0060] It should be noted that the size and position of the separation opening 12 are arranged according to the actual centrifugal separation box 61. The separation opening 12 is only simply shown in the drawings of the present application.

[0061] A second filtering assembly 7 is arranged in the casing 2, and is arranged between the air outlet pipe 4 and the first filtering assembly 6, and is used for further filtering the air to be filtered.

[0062] The second filtering assembly 7 comprises a grading filtering box 71 and a second collecting box 72. The grading filtering box 71 is fixedly connected to the inner side wall of the casing 2, and is provided with a filtering screen plate 13 inside, which is used for filtering the particulate impurities. The grading filtering box 71 is provided with a discharge port 14, and the second collecting box 72 is arranged at the discharge port 14, and is used for collecting the particulate impurities in the grading filtering box 71.

[0063] The second filtering assembly 7 is arranged as a combination of the grading filtering box 71 and the second collecting box 72, so that the second filtering assembly 7 can further intercept the particulate matters with large particle sizes in the air, and the intercepted particulate matters can be collected by the second collecting box 72, thereby realizing further filtering of the particulate matters with large particle sizes by the second filtering assembly 7.

[0064] It should be noted that the size and position of the discharge port 14 are arranged according to the centrifugal separation box 61.

[0065] The filtering screen plate 13 is arranged in multiple pieces, and the pore sizes of the multiple filtering screen plates 13 gradually decrease along the direction of air flow. In the embodiment, the filtering screen plate 13 is arranged in three pieces, and the pore sizes of the three filtering screen plates 13 gradually decrease along the direction of air flow, thereby realizing filtering of the particulate matters with different particle sizes in the air. In other embodiments, the filtering screen plate 13 can be arranged in two pieces, four pieces, or other numbers of pieces, which are all preferred embodiments of the application. It should be noted that no matter how many pieces of the filtering screen plate 13 are arranged, adaptive adjustment needs to be made according to the actual situation of the filtering structure.

[0066] The filtering screen plate 13 is arranged in multiple pieces, and the pore sizes of the multiple filtering screen plates 13 gradually decrease along the direction of air flow, so that the grading filtering box 71 can perform multiple grading filtering on the particulate matters with different particle sizes in the air, thereby further improving the filtering effect of the second filtering assembly 7.

[0067] In the embodiments of the present application, the first collecting box 62 and the second collecting box 72 are both slidably arranged on the casing 2. As can be seen from the drawings, the first collecting box 62 and the second collecting box 72 are both provided with a handle for pulling. Specifically, as to how the first collecting box 62 and the second collecting box 72 are detachably connected to the casing 2, it is only necessary to form a hole on the casing 2 for the first collecting box 62 and the second collecting box 72 to be inserted, which is easily conceived by those skilled in the art.

[0068] Slidably arranging the first collecting box 62 and the second collecting box 72 on the casing 2 makes it possible to quickly and conveniently clean the first filter assembly 6 and the second filter assembly 7 when cleaning is needed.

[0069] The third filter assembly 8 is located in the casing 2, and is located between the air outlet pipe 4 and the second filter assembly 7. The third filter assembly 8 is used to further filter the air to be filtered. The air to be filtered enters the air inlet pipe 3, sequentially flows through the first filter assembly 6, the second filter assembly 7, and the third filter assembly 8, and finally flows out of the air outlet pipe 4 and into the production equipment of the PVC rubber glove through the installation pipe 5. For the sake of expression, the activated carbon in the activated carbon box 81 and the fiber in the conductive fiber box 82 are not shown in the drawings of the embodiments of the present application. It should be noted that the activated carbon box 81 and the conductive fiber box 82 can also be pulled out of the casing 2.

[0070] The third filter assembly 8 includes an activated carbon box 81 and a conductive fiber box 82. The activated carbon box 81 and the conductive fiber box 82 are both fixedly connected to the inner side wall of the casing 2. The activated carbon box 81 and the conductive fiber box 82 are used to filter microorganisms in the air.

[0071] The third filter assembly 8 is arranged in the form of a combination of the activated carbon box 81 and the conductive fiber box 82. When the air, from which most of the particulate matters with large particle sizes have been filtered out, passes through the third filter assembly 8, most of the particulate matters with small particle sizes and microorganisms will be further adsorbed and filtered out, so that the third filter assembly 8 can effectively filter the air.

[0072] The magnetic control mechanism 9 is located between the rack 1 and the casing 2, and can drive the casing 2 to slide on the rack 1.

[0073] Referring to Figure 3 and Figure 4The magnetic control mechanism 9 comprises a control plate 91 and a control block 92, the control plate 91 is fixedly connected to the rack 1, the control plate 91 is provided with the first channel 15 and the second channel 16, the first channel 15 is provided along the direction of air flow, the first channel 15 is vertically arranged with the second channel 16, the first channel 15 is communicated with the second channel 16, the connecting rod 17 is fixedly connected to the cabinet 2, the connecting rod 17 is slidably arranged in the connecting groove 18, the control block 92 is slidably arranged in the first channel 15 and the second channel 16, the control plate 91 is further provided with the elastic element 19, the elastic element 19 is arranged in parallel with the second channel 16, the side wall of the first channel 15 close to the elastic element 19 is provided with the first magnet 20, the control block 92 is fixedly connected with the second magnet 21 close to the second channel 16, the first magnet 20 and the second magnet 21 repel each other.

[0074] The magnetic control mechanism 9 is arranged as the combination of the control plate 91 and the control block 92, so that when the first filter assembly 6, the second filter assembly 7 and the third filter assembly 8 installed in the cabinet 2 work for a period of time, the weight of the cabinet 2 increases due to the increasing impurities collected in the first filter assembly 6, the second filter assembly 7 and the third filter assembly 8, so that the cabinet 2 drives the control block 92 to move downward in the second channel 16, when the control block 92 moves to a certain position, the second magnet 21 on the control block 92 is repelled by the first magnet 20, so that the control block 92 is horizontally translated in the first channel 15, thereby driving the cabinet 2 to move horizontally away from the PVC rubber glove processing equipment, thereby effectively reducing the possibility of unfiltered air flowing into the PVC rubber glove processing equipment.

[0075] It should be noted that the elastic element 19 of the present application is a compression spring in the embodiment of the present application, and other forms of the elastic element 19 are also preferred embodiments of the present application.

[0076] It should be further noted that the selection of the elastic element 19, the first magnet 20, the second magnet 21 and the elastic element 19 in the embodiment of the present application is realized according to the needs of the present application and can be implemented.

[0078] The connecting rod 17 is provided as two, and the connecting groove 18 is provided with two, so that it is more stable during the process of the control block 92 driving the shell 2 to move transversely.

[0079] The implementation principle of the air filtering structure is as follows: during the production of the PVC rubber gloves, air enters from the air inlet pipe 3, and sequentially passes through the first filtering assembly 6, the second filtering assembly 7 and the third filtering assembly 8. The first filtering assembly 6 performs preliminary filtering on the air to preliminarily filter large particles in the air. The air filtered by the first filtering assembly 6 further passes through the second filtering assembly 7 to further filter particles in the air. Finally, the air filtered twice passes through the third filtering assembly 8, which filters small particles and microorganisms in the air, so that the air is effectively filtered and purified. The filtered air enters the PVC rubber glove production equipment through the air outlet pipe 4. When impurities in the air filtering structure accumulate to a certain degree, the magnetic control mechanism 9 pops out one end of the shell 2, thereby reminding the worker to clean or replace the filtering structure, thereby solving the problem that in the related art, the air filtering structure cannot be replaced in time, which easily produces defective products during production and seriously affects the yield of the PVC rubber gloves.

[0083] S3, after the production equipment of the PVC rubber gloves works for a period of time, the magnetic control mechanism 9 can pop out the entire shell 2;

[0084] S4, after the worker observes that the entire shell 2 is popped out, the worker cleans or replaces the first filtering assembly 6, the second filtering assembly 7 and the third filtering assembly 8.

[0085] The setting of the four steps S1-S4 can realize effective filtering of air in the production process of the PVC rubber gloves, the whole process is clear and the whole device is simple to use, the air entering the PVC rubber glove equipment can be effectively filtered, thereby to a certain extent, the problem that the air filtering structure in the related art usually cannot be replaced in time, leading to that defective products are easily produced in the production process and seriously affecting the yield of the PVC rubber gloves.
