[0002] Paper mills use papermaking machinery to manufacture household paper. If the formed household paper is to flow into the market, it needs to be packaged. The existing packaging methods include cutting the sheets of household paper according to needs and then rolling them up, or cutting and folding the household paper into packages according to needs. Whether rolling or packaging in packages, air cyclone blowers are used to adsorb the sheets of household paper onto the rewinding rollers, and then roll or cut or fold the paper. Therefore, air cyclone blowers are indispensable in the field of household paper packaging. For example: CN2279264Y, title: Rewinding and rewinding device for coreless roll household paper, discloses "a rewinding plate 5 having a cross section that is basically an involute and an air jet mechanism with a nozzle facing between the rewinding plate 5 and the roller 31". Although the patent discloses the jet mechanism, it does not give the specific working mode and jet method of the jet mechanism. Secondly, if the jet mechanism is used in the field of household paper packaging, it will inevitably cause cotton wool and papermaking on the household paper to block the pipeline of the jet mechanism, increase the noise of the entire equipment, and affect the physical and mental health of workers. Secondly, the household paper packaging process is in a dry environment, and fire is prone to occur when encountering open flames.

[0003] Therefore, there is an urgent need for an air cyclone blower that reduces the risk of jet mechanism blockage, reduces noise, and avoids fire. Utility Model Content

[0017] The utility model of a negative pressure device for folding paper has the following beneficial effects compared with the prior art:

[0018] The air cyclone blower provides suction to absorb the household paper that needs to be folded or packaged. The gas mixed with floccules and dust of the household paper enters the cyclone barrel along the air inlet pipe. Since the air inlet pipe is arranged at one end of the cyclone barrel close to the connecting pipe, the opening direction of the air inlet pipe is perpendicular to the axis of the cyclone barrel. When the gas, floccules and dust entering the air inlet pipe rotate along the side wall of the cyclone barrel, they gradually rotate around the inner wall of the cyclone barrel under the action of gravity, forming a cyclone in the cyclone barrel, which increases the residence time of the gas in the cyclone barrel and increases the probability of impurities such as floccules and dust falling into the bottom of the cyclone barrel under the action of gravity.

[0019] Because one end of the connecting pipe is connected to the top of the cyclone, the opening direction of the connecting pipe and the cyclone is parallel to the axis of the cyclone, and the connecting pipe opens downward and is at the top of the cyclone, which prevents flocs and dust from entering the connecting pipe, and prevents large suction force from sucking flocs and dust into air cyclone blowers and other equipment, affecting normal use, and plays an effect of filtering flocs and dust.

[0020] The filter barrel then performs a second filtration on the gas entering along the connecting pipe, fully avoiding the influence of impurities such as floccules and dust; the filter barrel and the cyclone are arranged side by side, and connected by the connecting pipe, which can not only filter out impurities such as floccules and dust, but also miniaturize the entire device to avoid the device being too large, and the filter barrel and the cyclone can be placed according to needs;

[0021] The docking port delivers the gas entering the filter barrel along the connecting pipe into the first cylinder body, and the gas entering the first cylinder body is then discharged from the exhaust port. During the discharge process, the gas is filtered again through the exhaust port to remove filter flocs, dust and other debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-6As shown, a negative pressure device for folding paper includes an air cyclone blower 1, a filter barrel 21, a cyclone barrel 22 and a connecting pipe 26, wherein the filter barrel 21 and the cyclone barrel 22 are arranged side by side, one end of the connecting pipe 26 is connected to the top of the cyclone barrel 22, the opening direction of the connecting pipe 26 at the connection between the connecting pipe 26 and the cyclone barrel 22 is arranged parallel to the axis of the cyclone barrel 22, and the other end of the connecting pipe 26 is connected to the bottom of the filter barrel 21; the cyclone barrel 22 is connected to an air inlet pipe 23, the air inlet pipe 23 is arranged at one end of the cyclone barrel 22 close to the connecting pipe 26, the opening direction of the air inlet pipe 23 is perpendicular to the axis of the cyclone barrel 22, and the side of the filter barrel 21 away from the connecting pipe 26 is connected to an air outlet pipe 24, and the air outlet pipe 24 is connected to the air cyclone blower 1. The air cyclone blower 1 provides suction to absorb the household paper that needs to be folded or packaged. The gas mixed with the floccules and dust of the household paper enters the cyclone barrel 22 along the air inlet pipe 23. Since the air inlet pipe 23 is arranged at one end of the cyclone barrel 22 close to the connecting pipe 26, the opening direction of the air inlet pipe 23 is perpendicular to the axis of the cyclone barrel 22. When the gas, floccules and dust entering the air inlet pipe 23 rotate along the side wall of the cyclone barrel 22, they gradually rotate around the inner wall of the cyclone barrel 22 under the action of gravity, forming a cyclone in the cyclone barrel 22, increasing the gas in the cyclone barrel 2 2, so that the probability of floccules, dust and other impurities falling into the bottom of the cyclone 22 under the action of gravity increases; and because one end of the connecting pipe 26 is connected to the top of the cyclone 22, the opening direction of the connecting pipe 26 and the cyclone 22 is parallel to the axis of the cyclone 22, and the connecting pipe 26 opens downward and is at the top of the cyclone 22, which prevents floccules and dust from entering the connecting pipe 26, and prevents large suction from sucking floccules, dust and other impurities into the air cyclone blower 1 and other equipment, affecting normal use, and plays the role of filtering floccules, dust and other impurities. The filter barrel 21 then performs a second filter on the gas entering along the connecting pipe 26, fully avoiding the influence of filtering floccules, dust and other impurities; the filter barrel 21 and the cyclone 22 are arranged side by side, and the connection position is connected by the connecting pipe 26, which can not only filter floccules, dust and other impurities, but also miniaturize the entire device to avoid the device being too large, and the filter barrel 21 and the cyclone 22 can be placed according to needs.

During the discharge process, the gas is filtered again through the exhaust ports 224 to remove impurities such as filter flocs and dust.

[0032] In order to improve the air tightness of the connection between the docking port 223 and the connecting pipe 26, and to prevent the flocculents and dust from entering the filter barrel 21 from between the docking port 223 and the connecting pipe 26, thereby affecting the filtering effect of the filter barrel 21, the connecting pipe 26 passes through the end of the filter barrel 21, and the edge of the docking port 223 is arranged around the end of the connecting pipe 26. The docking port 223 is arranged around the connecting pipe 26 to prevent the gas from flowing out from between the docking port 223 and the connecting pipe 26.

The dust cover 25 is detachably arranged on the mounting ring 211 by bolts, so as to facilitate the taking and fixing of the first cylinder 22.

[0036] In order to facilitate the removal of the dust cover 25 , the dust cover 25 includes a recessed shell 251 , in which a handle 252 is provided. The recessed shell 252 increases the strength of the dust cover 25 , and the handle 252 is used to facilitate the removal of the dust cover 25 .
