[0001] The utility model belongs to the technical field of filtering and dust removal, and more specifically, relates to a filter bag dust collector structure and an automatic bagging machine. Background Art

[0002] The dust collector is an important component of the automatic unpacking machine. The material packages are unpacked in the automatic unpacking machine, and dust is generated during the unpacking process. In order to prevent the dust from overflowing, a dust collector needs to be configured to maintain negative pressure in the automatic unpacking machine.

[0003] In existing dust collectors, the folded dust filter is prone to clogging during use, and the back-blowing device cannot completely blow open the blocked pores of the dust filter, so the dust filter needs to be frequently disassembled for spraying and flushing. In order to prevent the cleaning liquid from entering the dust collector chamber, the automatic unpacking machine needs to disassemble the dust filter when performing spray cleaning. It is strictly forbidden to use water to clean the inside of the dust filter. A sealing device needs to be used to seal the open end of the dust filter, and the dust filter needs to be flushed offline separately, which is very inconvenient. Utility Model Content

[0022] The utility model provides a filter bag dust collector structure. Compared with the prior art, the dust filter element assembly is installed on one side of the dust collector chamber 1 through a connector 3, and the dust filter element assembly is located in the unpacking machine chamber. In the unpacking state, the dust collector chamber 1 maintains a negative pressure. Under the action of atmospheric pressure, the dust in the unpacking machine chamber flows to the dust collector chamber 1 with the air flow, and the dust in the air flow is blocked on the outer surface by the dust filter element assembly. The air flow entering the dust filter element assembly enters the dust collector chamber 1 through the air intake gap, and the backflush pipe 2 intermittently blows positive pressure air into the dust filter element assembly, so that the dust attached to the outer surface of the dust filter element assembly falls into the discharge bin at the bottom of the unpacking machine chamber. In the cleaning state, the dust filter element assembly is removed from the dust collector chamber 1 through the connector 3, and the plugging sleeve 4 is installed on the middle hole of the connector 3. The dust filter element assembly is then installed on the dust collector chamber 1 using the connector 3. One end of the plugging sleeve 4 extends to the inside of the dust collector chamber 1, and the other end is covered and blocked on the outside of the extension section 201 of the backflush pipe 2. At this time, the connector 3 of the dust filter element assembly is in a closed state, and the backflush pipe 2 is also in a closed state, so washing water can be used to spray and rinse in the unpacking machine chamber, and the washing water will not enter the dust collector chamber 1. The utility model provides a filter bag dust collector structure, which can clean the dust filter element assembly when it is installed, and the washing water will not enter the dust collector chamber 1. There is no need to clean the dust filter element offline separately, and the operation is convenient.

[0023] Among them, the sealing sleeve 4 is a sealing component used to seal the air intake gap between the connector 3 and the backblowing pipe 2 and the internal sealing component of the backblowing pipe 2. Compared with the sealing component for sealing the dust removal filter element in the offline state, it has a smaller volume and reduces the manufacturing cost.

In addition, the filter bag body 10 is a filter bag woven from long fibers, so that the filter bag can be soaked and cleaned, which greatly improves the convenience of cleaning the filter element. The connector 3 is welded and fixed to one end of the filter mounting frame to facilitate the rapid disassembly and assembly of the filter mounting frame and the filter bag body 10 with the dust collector chamber 1.

[0025] Specifically, the filter mounting frame includes a plurality of support ribs 5 and a plurality of fixing rings 6, wherein the plurality of support ribs 5 are arranged along the length direction of the back-blowing tube 2 and are arranged around the outer periphery of the back-blowing tube 2, and the plurality of fixing rings 6 are sequentially sleeved and fixed to the outer periphery of the plurality of support ribs 5 at intervals along the length direction of the back-blowing tube 2, and the connector 3 is welded and fixed to the same end of the plurality of support ribs 5. The plurality of support ribs 5 and the plurality of fixing rings 6 are welded and fixed to form a supporting mesh cylinder, and the filter bag body 10 can be conveniently sleeved on the outside of the supporting mesh cylinder to form a supporting skeleton of the dust removal filter element.

[0026] Among them, one end of the filter bag body 10 has an open end, and a mounting groove is opened on the outer periphery of the connecting head 3. The open end of the filter bag body 10 is sleeved in the mounting groove, and the open end of the filter bag body 10 is pressed into the mounting groove by using the throat clamp 7, so as to close the open end of the filter bag body 10, and at the same time improve the stability of the filter bag body 10 and the filter mounting frame.

[0027] Specifically, an air inlet is provided on one side of the dust collector chamber 1, and an inlet flange 11 is installed in the air inlet. The inner circumferential wall of the inlet flange 11 is provided with an internal thread, and the outer circumferential wall of the connecting head 3 is provided with an external thread. The connecting head 3 is threadedly connected to the inside of the inlet flange 11 through the matching structure of the above-mentioned internal thread and external thread.

[0028] In order to ensure the sealing performance between the inlet flange 11 and the connecting head 3 , an elastic outer sealing ring 8 is provided between the inlet flange 11 and the connecting head 3 .

[0029] Specifically, a section of the outer peripheral wall of the blocking sleeve 4 is provided with an external thread, and the inner wall of the middle hole is provided with an internal thread.
