Description

Technical Field

[0001] The utility model relates to the technical field of vacuum filters, in particular to a vacuum filter sealing tool. Background Art

[0002] The vacuum filter collects pollutants sucked in from the atmosphere to prevent system pollution. It is used between the suction cup and the vacuum generator. A silencer should be installed at the exhaust port of the vacuum generator, the suction port or exhaust port of the vacuum valve, and the exhaust port of the vacuum pump. When the vacuum filter is sealed, a sealing ring needs to be installed inside the filter, and the sealing ring is generally placed at the spiral connection end of the vacuum filter. When the connection end of the vacuum filter is spirally connected, if the force of the spiral connection is too large, pressure will be applied to the sealing ring, thereby causing the seal to rupture. If the force is too small, the connection between the sealing ring and the connection end will not be tight enough. Therefore, a vacuum filter sealing tool is provided to solve the problems raised in the above background technology. Utility Model Content

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] See also Figures 1 to 5 A vacuum filter sealing tool comprises a placing cylinder 1, a bottom cylinder 2 is installed at the lower side of the placing cylinder 1, a vacuum pump 202 is installed inside the bottom cylinder 2, the input end of the vacuum pump 202 is connected to the bottom wall of the placing cylinder 1, a rotating cylinder 3 is arranged on the upper side of the placing cylinder 1, a fixed cylinder 301 is rotatably connected at the lower side of the rotating cylinder 3, a plurality of fixed springs 302 are fixedly connected at the upper side of the fixed cylinder 301, a fixed disk 303 is fixedly connected at the upper side of the fixed spring 302, a plurality of fixed blocks 304 are fixedly connected on the fixed disk 303, a sliding rod 306 is slidably connected inside the rotating cylinder 3, wherein the sliding rod 306 is rectangular and moves up and down inside the rotating cylinder 3, one end of the sliding rod 306 is fixedly connected to a fixing plate 307, a plurality of positioning blocks 308 are fixedly connected on the fixing plate 307, and the positioning blocks 308 and the fixing blocks 304 are matching components.

[0025] When the cylinder cover is tightly connected to the cylinder body, when the rotating cylinder 3 is rotated again, the resistance between the cylinder cover and the cylinder body increases, and the fixed spring 302 will bend when the rotating cylinder 3 rotates (that is, the rotating cylinder 3 can no longer drive the fixed cylinder 301 to rotate through the fixed spring 302). The bending of the fixed spring 302 can be understood as tilting left and right, and because the torsion is too large, the fixed spring 302 will be deformed, and the resistance generated when the card slot between the positioning card block 308 and the fixed block 304 is engaged is less than the torsion generated when the rotating cylinder 3 rotates, thereby causing The fixing plate 307 can no longer engage with the fixing block 304 on the fixing disk 303 through the positioning block 308 until the rotating cylinder 3 starts to idle (the fixing plate 307 cannot drive the fixing disk 303 to rotate). After the rotating cylinder 3 idles, the cylinder cover can no longer apply pressure to the cylinder body, so that the pressure received by the sealing ring between the cylinder cover and the cylinder body is within a reasonable range, thereby protecting the sealing ring at the connecting end of the vacuum filter, preventing the sealing ring from being damaged due to the overly tight connection between the vacuum filter cylinder body and the cylinder cover, and improving the sealing performance of the vacuum filter.

[0026] Preferably, Figure 1 and Figure 4 As shown, an exhaust port 201 is provided on the side of the bottom cylinder 2, and the output end of the vacuum pump 202 is connected to the exhaust port 201. A first ventilation plate 203 is fixedly connected to the bottom cylinder 2, and a second ventilation plate 204 is rotatably connected to the upper side of the first ventilation plate 203. A plurality of air inlet holes 205 are provided on the first ventilation plate 203 and the second ventilation plate 204.

[0027] Among them, the vacuum pump 202 adsorbs the filter body through the air inlet hole 205 to fix the position of the filter body inside the placement cylinder 1, and the second ventilation plate 204 can be rotated so that the multiple air inlet holes 205 on the second ventilation plate 204 are not completely aligned with the multiple air inlet holes 205 on the first ventilation plate 203, thereby reducing the adsorption force of the vacuum pump 202 on the filter body inside the placement cylinder 1.

[0028] Preferably, Figure 3 As shown, the inner wall of the placement cylinder 1 is hingedly provided with multiple rubber pads 101. When the filter cylinder body is inserted into the placement cylinder 1, the rubber pads 101 will bend. When the rubber pads 101 contact the filter cylinder body, the friction between the filter cylinder body and the placement cylinder 1 will be increased, so that the filter cylinder body will not rotate inside the placement cylinder 1.

[0029] Preferably, Figure 6-7As shown, a working chamber 405 is opened inside the fixed cylinder 301, and a rotating rod 404 is rotatably connected inside the working chamber 405, and a spiral sleeve 402 is rotatably connected inside the working chamber 405. The rotating rod 404 and the spiral sleeve 402 are meshed through a bevel gear 403. The spiral sleeve 402 is spirally connected to a spiral rod 401, and one end of the spiral rod 401 is rotatably connected to a clamping rod 4, which is slidably connected inside the fixed cylinder 301.

[0030] Rotate the rotating rod 404. When the rotating rod 404 rotates, the spiral sleeve 402 can be driven to rotate through the bevel gear 403. When the spiral sleeve 402 rotates, the spiral rod 401 can be moved inside the fixed cylinder 301, and then the clamping rod 4 can be moved into the fixed cylinder 301, which can fix the filter body inside the fixed cylinder 301. The clamping rod 4 is rectangular, so that when the spiral rod 401 moves inside the spiral sleeve 402, it can drive the clamping rod 4 to clamp the filter body.

[0031] Preferably, a threaded rod 305 is rotatably connected inside the rotating cylinder 3 , and the threaded rod 305 is spirally connected to the sliding rod 306 .

[0032] Among them, when it is necessary to adjust the torque of the rotating cylinder 3, hold the rotating cylinder 3, fix the position of the rotating cylinder 3, and then rotate the threaded rod 305 clockwise, the sliding rod 306 can be moved in the direction of the fixed disk 303 in the rotating cylinder 3 through the threaded rod 305, so that the fixed plate 307 is connected to the fixed disk 303, and the slot between the positioning block 308 and the fixed block 304 is engaged. When the fixed plate 307 gradually moves downward, it will exert a pressure on the fixed disk 303, and the fixed spring 302 will gradually compress, and the compressed fixed spring 302 will not easily bend (the torque generated between the fixed cylinder 301 and the fixed spring 302 increases), so the torque between the rotating cylinder 3 and the fixed cylinder 301 can be adjusted.

[0033] Preferably, the adjacent ends of the positioning block 308 and the fixing block 304 are both provided with arc chamfers.

[0034] The arc chamfer can cause the fixing spring 302 to deform when the torque is too large, and the positioning block 308 and the fixing block 304 to become loose when they are engaged, that is, the fixing plate 307 cannot drive the fixing disk 303 to rotate.

[0035] Preferably, a plurality of pressure sensors are installed on the fixing cylinder 301 , and the fixing spring 302 is connected to the pressure sensors.

[0036] When the fixing cylinder 301 moves downward, pressure is applied to the pressure sensor through the fixing spring 302 , and the torque of the fixing cylinder 301 can be set according to the pressure value.

[0037] The working principle of the utility model is as follows: the body of the vacuum filter is placed inside the placement cylinder 1, and then the vacuum pump 202 is started to adsorb the body of the vacuum filter through the air inlet 205, the position of the vacuum filter body is fixed, and the rotating rod 404 is rotated. When the rotating rod 404 rotates, the spiral sleeve 402 can be driven to rotate through the bevel gear 403. When the spiral sleeve 402 rotates, the spiral rod 401 can be moved inside the fixed cylinder 301, and then the clamping rod 4 can be moved into the fixed cylinder 301, which can fix the filter body inside the fixed cylinder 301, and then the rotating cylinder 3 is aligned with the placement cylinder 1, the cylinder cover is closed on the cylinder body, and the rotating cylinder 3 is rotated, so that the cylinder cover can be spirally connected with the cylinder body through the fixed cylinder 301;

[0038] When the cylinder cover is tightly connected to the cylinder body, when the rotating cylinder 3 is rotated again, the fixing spring 302 will be deformed and bent, and because the torsion is too large, the fixing spring 302 will be deformed, and the resistance generated when the slot between the positioning block 308 and the fixing block 304 is engaged is less than the torsion generated when the rotating cylinder 3 rotates, and then the fixing plate 307 can no longer engage with the slot on the fixing disk 303 through the positioning block 308, until the rotating cylinder 3 idles (the fixing plate 307 cannot drive the fixing disk 303 to rotate). After the rotating cylinder 3 idles, the cylinder cover cannot apply pressure to the cylinder body again, so that the pressure received by the sealing ring between the cylinder cover and the cylinder body is within a reasonable range, thereby protecting the sealing ring at the connecting end of the vacuum filter, preventing the sealing ring from being damaged due to the overly tight connection between the vacuum filter cylinder body and the cylinder cover, and improving the sealing performance of the vacuum filter.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
