There are many types of paper towels, including tissue paper, roll paper, etc. Among them, tissue paper is popular among the public because of its convenience. At present, tissue paper needs to be folded, which is mainly achieved by a paper towel folding machine. In the process of producing paper towels by the paper towel folding machine, a large amount of paper scraps will be generated, and the paper scraps can easily clog the filter of the vacuum pump. The current traditional method is to clean the metal filter every day, otherwise there will be a risk of insufficient suction of the vacuum pump or damage to the vacuum pump; among them, a vacuum pump is a type of vacuum pump, which is a conveying machine that directly provides energy to the liquid in the form of pressure energy through the reciprocating motion of the piston.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] Refer to the instruction manual Figure 1-Figure 3 As shown;

[0034] An improved split cyclone filter device for a paper scrap separation energy-saving pump comprises an adsorption structure 1 and a collection structure 2:

[0035] The adsorption structure 1 includes a dust suction unit 11 and a scrap suction unit 12 which are laid along the transmission direction of the paper towel. The dust suction unit 11 is used to absorb dust on the surface of the paper towel, and the scrap suction unit 12 is used to absorb scraps after cutting the paper towel. By adsorbing the dust on the surface of the paper towel and the scraps generated when cutting the paper towel separately, the dust and scraps pollution on the paper towel production line is effectively reduced, thereby improving the cleanliness and quality of the final product, and preventing more dust from being collected in the subsequent paper scrap collection process, reducing the quality of the collected scraps, and realizing the reuse of waste through the recycling of scraps, realizing the concept of sustainable environmental protection;

[0036] The device separates and absorbs the dust on the surface of the paper towel and the paper scraps generated when cutting the paper towel, and uses the characteristics of the cyclone filter unit 22 to separate the paper scraps and dust through the high-speed vortex of the fluid, and a filter screen is added to the top of the cyclone filter unit 22 to prevent the paper scraps from falling due to gravity due to their light weight. At the same time, the two-stage dust filtering function prevents the filter screen of the subsequent vacuum pump 4 from being blocked.

[0037] Specifically, the dust collection unit 11 includes a dust collection box 111, a connecting pipe 112 and a dust collecting pipe 113. The dust collection box 111 is connected to the dust collecting pipe 113 through the connecting pipe 112. A rotating component 114 is installed inside the dust collecting pipe 113. The rotating component 114 passes through the pipe wall of the dust collecting pipe 113 and is connected to a motor 115. A long plate 116 for limiting the motor 115 is fixed to the surface of the motor 115. The long plate 116 is fixed to the side wall of the dust collection box 111. The long plate 116 is used to limit the position of the motor 115. A dust outlet pipe 117 is provided at one end of the dust collecting pipe 113 close to the collection structure 2.

[0038] Specifically, the rotating assembly 114 includes a round rod located inside the dust collecting tube 113 and multiple sets of turbines evenly spaced on the surface of the round rod. The multiple sets of turbines are arranged linearly, and each set of turbines has multiple pieces, and the multiple pieces of turbines are arranged at equal angles along the circumference of the surface of the round rod.

[0039] Among them, the motor 115 drives the rotating component 114 to rotate, so that the turbine distributed on the surface of the round rod rotates to disturb the airflow in the dust collecting pipe 113 to move in a directional manner, so that the airflow in the dust collecting pipe 113 tends to flow toward the dust outlet pipe 117. Among them, a plurality of strip-shaped air suction ports are opened on the surface along the dust box 111, and the plurality of strip-shaped air suction ports span the paper towel to prevent the occurrence of adsorption dead corners. During the transmission process of the paper towel, the dust box 111 is tightly attached to the surface of the paper towel to adsorb dust on the surface of the paper towel. At the same time, the pressure difference between the inner and outer cavities of the dust box 111 gives a certain pressure to the transmitted paper towel to further stretch the paper towel.

[0040] Specifically, the chip suction unit 12 includes a chip suction box 121, a second connecting pipe 122 and a chip collecting pipe 123. The chip suction box 121 is connected to the chip collecting pipe 123 through the second connecting pipe 122. The chip suction unit 12 is provided with a driven component 13 installed inside the chip collecting pipe 123. The driven component 13 and the rotating component 114 have the same structure, and both of them move in a directional manner by rotating to disturb the airflow in the chip collecting pipe 123. A synchronous belt 14 is provided between the driven component 13 and the rotating component 114, and the driven component 13 and the rotating component 114 are linked by the synchronous belt 14. The driven component 13 rotates synchronously with the rotating component 114 through the synchronous belt 14. The chip suction box 121 is provided with a chip suction port at one end close to the paper towel, which is used to collect debris and particle dust generated after the paper towel is cut, to ensure that the folded paper towel is not mixed with impurities, and to improve the quality of the paper towel product;

[0041] The driven component 13 rotates so that the debris and particulate dust enter the chip suction box 121 and the chip collecting pipe 123 through the chip suction port, and then are discharged. The discharged airflow has a specific speed.

[0042] Secondly, the device first absorbs the dust on the paper towel, so that the amount of dust sucked into the dust suction port is less, which is convenient for the subsequent separation of paper scraps, and also prevents the sieve in the vacuum pump 4 from being blocked due to excessive dust;

[0043] The bottom end of the paper towel is attached to a frame 5, and the frame 5 includes a workbench 51 and a leg 52 for raising the workbench 51. A limiting cylinder 1 53 and a limiting cylinder 2 54 for limiting the positions of the dust collecting unit 21 and the cyclone filter unit 22 are provided on one side of the frame 5 close to the collecting structure 2, wherein the dust collecting unit 21 and the limiting cylinder 1 53, and the cyclone filter unit 22 and the limiting cylinder 2 54 are plug-in connected.

[0044] Specifically, multiple groups of positioning plates 55 are fixed on both sides of the workbench 51, and multiple transmission rollers 6 are rotatably installed inside the multiple groups of positioning plates 55. The transmission rollers 6 are rotated to transmit paper towels to realize the transmission of paper towels. A gap is formed between the transmission rollers 6 and the workbench 51 for paper towels to pass through. The gap allows paper towels to pass through and gives the paper towels a certain squeezing force, stretching the paper towels to make them flat and smooth. A semicircular groove 57 is opened on the surface of the workbench 51. The semicircular groove 57 is used to place the dust collection unit 11. The purpose of this arrangement is to make the strip-shaped air intake port of the dust collection box 111 contact more with the surface of the paper towel, thereby increasing the effective area of ​​dust collection, improving the efficiency of dust collection, and improving the cleanliness of the surface of the paper towel.

[0045] Embodiment 2

[0046] Refer to the instruction manual Figure 4 , Figure 5 and Fig. 9 As shown;

[0047] The collecting structure 2 includes a dust collecting unit 21 and a cyclone filter unit 22 which are respectively connected to the dust suction unit 11 and the scrap suction unit 12. The scraps are blocked by a filter net arranged at the top of the cyclone filter unit 22. A collecting bucket 3 is arranged at the bottom of the cyclone filter unit 22, and a vacuum pump 4 is arranged at one end of the collecting bucket 3 away from the cyclone filter unit 22. The scraps retained in the cyclone filter unit 22 are collected by the collecting bucket 3 through the suction force of the vacuum pump 4.

[0048] A filter is also installed at the connection between the collecting barrel 3 and the vacuum pump 4 , the purpose of which is to collect paper scraps in the collecting barrel 3 .

[0049] A semicircular groove 57 is provided on the surface of the workbench 51, which is used to place the dust suction unit 11, and two groups of clamps 58 for limiting are provided at both ends of the dust suction unit 11 and the chip suction unit 12. The two groups of clamps 58 respectively engage the dust suction unit 11 and the chip suction unit 12 to limit the position of the dust suction unit 11 and the chip suction unit 12, and realize the detachable connection between the dust collecting unit 21 and the cyclone filter unit 22 and the frame 5 through plug-in connection. The detachable connection also ensures that the positions of the dust collecting unit 21 and the cyclone filter unit 22 are fixed; a chip discharge pipe 124 is provided at one end of the chip suction unit 12 close to the collecting structure 2, and the chip discharge pipe 124 is snap-fittedly connected to the first pipe 221, and the detachable connection between the chip suction unit 12 and the cyclone filter unit 22 is realized through plug-in connection.

[0050] A first pipe 221 is provided in the tangential direction of the cyclone filter unit 22, and the first pipe 221 is used to connect the cyclone filter unit 22 with the scrap suction unit 12. A second pipe 222 is provided at the top of the cyclone filter unit 22, and the second pipe 222 is used to connect the cyclone filter unit 22 with the dust collection unit 21. The paper scraps and dust collected by the scrap suction unit 12 enter the cyclone filter unit 22 through the first pipe 221; the dust collection unit 21 includes a dust collection lower box 211 and a dust collection upper box 212 connected by plug-in connection. A bent pipe 213 is provided at the center of the top of the dust collection upper box 212. The bent pipe 213 is pressed down and buckled on the dust outlet pipe 117, and the dust collected by the dust collection unit 11 is discharged. The paper scraps enter the dust collecting unit 21 through the dust outlet pipe 117 and the bent pipe 213, and are retained by the lower dust collecting box 211 and the upper dust collecting box 212. The paper scraps and dust in the cyclone filter unit 22 are separated under the action of centrifugal force, and the dust enters the dust collecting unit 21 through the second pipe 222. The dust is collected by the dust collecting unit 21. The bottom end of the cyclone filter unit 22 is provided with a chip outlet, and the collecting barrel 3 is covered at the chip outlet of the cyclone filter unit 22. The collecting barrel 3 collects the paper scraps, and at the same time, the paper scraps in the collecting barrel 3 are extracted to another place by the vacuum pump 4 to realize the collection of the paper scraps. The vacuum pump 4 is a variable frequency vacuum pump, which can automatically adjust the flow rate and lift of the pump to achieve energy saving.

[0051] Specifically, a first pipe 221 is provided in the tangential direction of the cyclone filter unit 22, and the first pipe 221 is used for the cyclone filter unit 22 to communicate with the debris suction unit 12, and the debris adsorbed by the debris suction unit 12 enters the cyclone filter unit 22 through the first pipe 221. A second pipe 222 is provided at the top of the cyclone filter unit 22, and the cyclone filter unit 22 is connected to the dust collection unit 21 through the second pipe 222, so as to guide the dust passing through the filter into the dust collection unit 21;

[0052] It should be noted that a ball valve (not shown) is disposed inside the second pipe 222, and the opening and closing of the ball valve are synchronized with the driven component 13 and the rotating component 114. When the driven component 13 and the rotating component 114 stop rotating, the ball valve is closed and the vacuum pump 4 is turned on. The purpose of the ball valve is to prevent the negative pressure generated by the vacuum pump 4 from causing the dust collected by the dust collecting unit 21 to be discharged again through the second pipe 222.

[0053] Secondly, an airflow with a certain speed enters the cyclone filter unit 22 tangentially from the first pipe 221, so that a vortex is generated in the cyclone filter unit 22, and dust enters the dust collecting unit 21 from the second pipe 222. It should be noted that at this time, the vacuum pump 4 is in the notification state, and the ball valve, the driven component 13 and the rotating component 114 and the vacuum pump 4 are intermittently opened. When the ball valve, the driven component 13 and the rotating component 114 are opened, the vacuum pump 4 is in the closed state; when the ball valve, the driven component 13 and the rotating component 114 are closed, the vacuum pump 4 is in the open state.

[0054] In order to prevent paper scraps and dust from flowing out with the air flow, a filter net is added at the top outlet of the cyclone filter unit 22. By changing the start and stop of the vacuum pump 4, the situation that the paper scraps are not easy to fall due to gravity due to their light weight is improved, and the paper scraps can be collected. At the same time, through the two-pass dust filtering function, the subsequent filter net of the vacuum pump 4 is prevented from being blocked.

[0055] Embodiment 3

[0056] Refer to the instruction manual Figure 6-Figure 8 As shown;

[0057] Two groups of semicircular baffle bars are fixed on the inner wall of the lower dust collecting box 211, which are respectively used to support the ventilation plate 215 and the filter plate 216. The two groups of semicircular baffle bars include a plurality of semicircular baffle bars 214 distributed in a ring shape with equal intervals. A vortex component 217 is engaged with the surface of the ventilation plate 215. The vortex component 217 passes through the filter plate 216 and is engaged with a group of dust sweeping components 218.

[0058] Specifically, the vortex assembly 217 includes a central rod and a plurality of vortex blades fixed to the surface of the central rod. The plurality of vortex blades are fixed to the bottom end of the central rod at the same angle. When an airflow with a certain speed flows through the vortex blades, the vortex blades are subjected to resistance and spin.

[0059] Specifically, the dust sweeping assembly 218 is engaged with the inside of the central rod. When the vortex assembly 217 rotates, the dust sweeping assembly 218 sweeps the dust on the surface of the filter plate 216 to prevent the dust on the surface of the filter plate 216 from accumulating too thickly, causing the filter plate 216 to be unable to sieve, resulting in excessive pressure in the dust collecting upper box 212 and airflow being unable to be introduced; the filter plate 216 includes a filter frame 2161 and a filter mesh cloth 2162 connected as one body, and a central hole 2163 and a through hole 2164 are opened on the surface of the filter plate 216. The central hole 2163 is for the vortex assembly 217 to pass through, and a collecting box 2165 is provided below the through hole 2164. The collecting box 2165 is fixed on the lower surface of the filter frame 2161. The dust swept by the dust sweeping assembly 218 passes through the through hole 2164 into the collecting box 2165, so as to realize dust collection and continuously sweep the dust on the surface of the filter plate 216 to ensure the filtering efficiency of the filter plate 216.

[0060] Among them, the dust sweeping assembly 218 includes a circular sweeping rod engaged inside the center rod and a sweeping plate fixed on the surface of the sweeping rod. The dust sweeping assembly 218 collides with the dust on the surface of the filter cloth 2162 and then shakes. The shaking dust sweeping assembly 218 reduces the squeezing force between the dust sweeping assembly 218 and the filter cloth 2162, thereby preventing the dust sweeping assembly 218 from being excessively scratched and causing damage to the surface of the filter cloth 2162.

[0061] Specifically, the device is provided with a dust suction unit 11 and a debris suction unit 12, and the dust suction unit 11 and the debris suction unit 12 jointly absorb dust on the surface of the paper towel and debris caused by cutting, thereby ensuring the cleanliness of the paper towel and ensuring the quality of the paper towel produced by the paper towel folding rack;

[0062] The device is provided with a dust suction unit 11 and a scrap suction unit 12. The dust suction unit 11 is used to suction dust from the driven paper towels, so that the scrap suction unit 12 is prevented from sucking in too much dust, which is mixed in the paper scraps, resulting in the need to re-screen the paper scraps when they are recycled. At the same time, a cyclone filter unit 22 is connected to the tail of the scrap suction unit 12. The cyclone filter unit 22 causes the paper scraps and dust to vortex, and the paper scraps and dust are separated by centrifugal force, thereby ensuring the accuracy of the produced paper scraps.

[0063] Specifically, the filter plate 216 includes a filter frame 2161 and a filter cloth 2162 which are connected as one body. A center hole 2163 and a through hole 2164 are provided on the surface of the filter plate 216. The center hole 2163 is for the vortex component 217 to pass through. A collecting box 2165 is provided below the through hole 2164. The dust swept by the dust sweeping component 218 passes through the through hole 2164 into the collecting box 2165 to collect the dust. The collecting box 2165 is fixed to the filter frame 2161 to limit the position.

[0064] The vortex component 217 is rotated by the flowing airflow, and the dust sweeping component 218 is linked to sweep the filter plate 216 to clean the filter plate 216 and ensure the filtering efficiency of the filter plate 216.

[0065] The device realizes the connection between the dust collecting unit 21 and the cyclone filter unit 22 through the second pipe 222, and introduces the dust in the cyclone filter unit 22 into the dust collecting unit 21, so as to prevent the dust from entering around the paper towel and contaminating the paper towel again;

[0066] The device is provided with a detachable connection between the dust suction unit 11, the scrap suction unit 12, the dust collection unit 21, the cyclone filter unit 22 and the frame 5, and the inner cavity of the dust suction unit 11, the scrap suction unit 12, the dust collection unit 21 and the cyclone filter unit 22 is cleaned regularly by disassembly and assembly, thereby ensuring the maximum efficiency of paper scrap classification;
