Description

Technical Field

[0001] This utility model relates to the field of air filter processing technology, specifically a corner-cutting device for air filter processing. Background Technology

[0002] Air filters are widely used in engineering vehicles, automobiles, agricultural vehicles, industrial filtration, laboratories, sterile operating rooms, and various precision operating rooms to filter impurities and particulate matter from the air and protect the normal operation of equipment. To ensure better installation of the air filter in the corresponding equipment, the edges and corners of the outer mounting plate are often cut at specific angles to match the installation space and connection structure.

[0003] Most currently used corner-cutting devices are inconvenient for cutting the outer fixing plate of the filter element and for replacing the cutter. During use, the inconvenience in cutting the workpiece leads to excessive time and effort required, and the inability to reciprocate the cutter results in low cutting efficiency and poor cutting effect, potentially causing deviations and defects in the cut workpiece. This reduces the practicality of the corner-cutting device. Furthermore, the inconvenience in replacing the cutter leads to wear and dulling after prolonged use, further deteriorating the cutting effect and efficiency, and even rendering the cutter unusable for corner cutting. This also results in poor corner-cutting efficiency and effect. Additionally, the inconvenience in fixing the workpiece on the worktable during use can cause it to deviate under external force, leading to deviations in the cutting position or even preventing proper cutting. This reduces the stability and accuracy of the corner-cutting device. Utility Model Content

[0004] The purpose of this invention is to provide a chamfering device for processing air filter elements, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner-cutting device for air filter processing, comprising a worktable and a support frame. A corner-cutting replacement mechanism is provided on the top of the worktable, the mechanism including a groove. The top of the worktable has a groove. A first electric push rod is fixedly connected to the bottom of the support frame. A lifting plate is fixedly connected to the bottom end of the first electric push rod. A fixed plate is fixedly connected to the top of the lifting plate. A slide rail is fixedly connected to the inner side of the fixed plate. A slider is slidably connected to the outer wall of the slide rail. A component is fixedly connected to one side of the slider. A movable plate has a fixed strip fixedly connected to its top. A motor bracket is fixedly connected to the top of a lifting plate. A motor is fixedly connected to the inner side of the motor bracket. The output shaft of the motor is fixedly connected to a motor shaft via a coupling. A rotating plate is fixedly connected to the bottom of the motor shaft.

Connecting plates are fixedly connected to both sides of the connecting rod. A threaded rod is fixedly connected to the bottom of the connecting plate. A locking block is movably connected to the outer wall of the threaded rod. A nut is threadedly connected to the outer wall of the threaded rod.

[0006] As a preferred technical solution, the slider has a through hole inside, the shape and size of which match the shape and size of the slide rail, and the slider is slidably connected to the slide rail through the through hole.

[0007] As a preferred technical solution, the fixing strip is rectangular in shape, and there are two fixing strips.

[0008] As a preferred technical solution, the motor bracket is in the form of two brackets, which are symmetrically arranged with the vertical center line of the motor as the axis of symmetry.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a corner-cutting replacement mechanism, facilitates both corner cutting of workpieces and blade replacement. During use, the first electric push rod and motor drive the blade to reciprocate left and right, pressing down to cut the workpiece. The blade is replaced through the cooperation of the nut and threaded rod. This avoids the situation where corner cutting is difficult due to inconvenience, requiring excessive time and effort, and the inability to reciprocate the blade results in low cutting efficiency, poor cutting effect, and potential deviations and defects in the cut workpiece. This ensures the practicality of the corner-cutting device and also prevents the blade from becoming dull and worn after prolonged use due to inconvenience in blade replacement, which would lead to a decrease in cutting effect and efficiency, or even the inability to use the blade for corner cutting. This guarantees the corner-cutting efficiency and effect of the corner-cutting device.

[0015] 2. This utility model, through the setting of the fixing mechanism, can achieve the function of fixing the workpiece. During use, by activating the second electric push rod, the pressure plate is driven to descend, so that the pressure plate fixes the workpiece. This can avoid the situation where the workpiece is subjected to external force during cutting due to the inconvenience of fixing the workpiece on the worktable, causing the workpiece to deviate, resulting in deviation of the cutting position of the workpiece, or the inability to cut the workpiece normally. This ensures the stability and accuracy of the corner cutting device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 As shown, the present invention provides the following technical solution, including a workbench 1 and a support frame 4. A corner-cutting replacement mechanism 2 is provided on the top of the workbench 1, and a fixing mechanism 3 is provided on one side of the workbench 1.

[0025] Specifically: When the corner cutting device is needed to cut the corner of a workpiece, the workpiece is first placed on the worktable 1 and positioned at the correct angle. The corner to be cut is placed on the groove 201. After placement, the workpiece needs to be fixed by the fixing mechanism 3. Once fixed, the corner cutting can begin. The corner cutting mechanism 2 is used to cut the corner of the workpiece. After the cutter 215 has been used for a long time, it will become dull and needs to be replaced. The corner cutting mechanism 2 is used to replace the cutter 215 to complete the work.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a chamfering mechanism 2 is provided on the top of the workbench 1. The chamfering mechanism 2 includes a groove 201. The top of the workbench 1 has a groove 201. A first electric push rod 202 is fixedly connected to the bottom of the support frame 4. A lifting plate 203 is fixedly connected to the bottom end of the first electric push rod 202. A fixed plate 204 is fixedly connected to the top of the lifting plate 203. A slide rail 205 is fixedly connected to the inner side of the fixed plate 204. A slider 206 is slidably connected to the outer wall of the slide rail 205. A moving plate 207 is fixedly connected to one side of the slider 206. A fixing strip 208 is fixedly connected to the top of the moving plate 207. A motor bracket 209 is fixedly connected to the top of the lifting plate 203. A motor 210 is fixedly connected to the inner side of the motor bracket 209. The output shaft of the motor 210 is fixedly connected to a motor shaft 211 through a coupling. A rotating plate 212 is fixedly connected to the bottom end of the motor shaft 211. A fixed shaft is fixedly connected to the bottom of the rotating plate 212. 213. A connecting rod 214 is fixedly connected to the bottom of the movable plate 207. A connecting plate 216 is fixedly connected to both sides of the connecting rod 214. A threaded rod 217 is fixedly connected to the bottom of the connecting plate 216. A locking block 218 is movably connected to the outer wall of the threaded rod 217. A nut 219 is threadedly connected to the outer wall of the threaded rod 217. A through hole is opened inside the slider 206. The shape and size of the through hole match the shape and size of the slide rail 205. The slider 206 is slidably connected to the slide rail 205 through the through hole. The fixed strip 208 is rectangular in shape, and there are two fixed strips 208. There are two motor brackets 209. The two motor brackets 209 are symmetrically arranged with the vertical center line of the motor 210 as the axis of symmetry. The vertical center line of the connecting rod 214 coincides with the vertical center line of the movable plate 207. The connecting rod 214 is L-shaped. The connecting plate 216 is rectangular in shape, and there are two connecting plates 216.

[0027] Once fixed, the corner-cutting process can begin. Motor 210 drives motor shaft 211 to rotate, which in turn drives rotating plate 212. Rotating plate 212 then drives fixed shaft 213 in a circular motion. Fixed shaft 213, via fixed strip 208 on moving plate 207, drives moving plate 207 in a reciprocating motion. During the movement of moving plate 207, the sliding of slider 206 on the outer wall of slide rail 205 ensures smoother and more stable movement. Moving plate 207 drives connecting rod 214 in a reciprocating motion, which in turn drives cutter 215 in a reciprocating motion. Then, the first electric push rod 202 is activated, causing it to extend... The first electric push rod 202 drives the lifting plate 203 to descend, and the lifting plate 203 drives the cutter 215 to descend, so that the cutter 215 moves back and forth repeatedly, pressing down and cooperating with the groove 201 to cut the corner of the workpiece, thereby completing the corner cutting work. When the cutter 215 has been used for a long time, the cutter 215 will become dull. At this time, the cutter 215 needs to be replaced. Then, the nut 219 is rotated out from the outer wall of the threaded rod 217, and then the locking block 218 on the cutter 215 is removed from the outer wall of the threaded rod 217. Then, the locking block 218 on the new cutter 215 is inserted into the outer wall of the threaded rod 217, and then the nut 219 is rotated and inserted into the outer wall of the threaded rod 217 to fix the cutter 215, thereby completing the replacement work.

[0028] like Figure 1 and Figure 6 As shown, a fixing mechanism 3 is provided on one side of the workbench 1. The fixing mechanism 3 includes a fixing frame 301. The fixing frame 301 is fixedly connected to one side of the workbench 1. A second electric push rod 302 is fixedly connected to the bottom of the fixing frame 301. A pressure plate 303 is fixedly connected to the bottom end of the second electric push rod 302.

[0029] After the workpiece is placed, it needs to be fixed in place. At this time, the second electric push rod 302 is activated, which extends the second electric push rod 302 and drives the pressure plate 303 to descend, so that the pressure plate 303 clamps and fixes the workpiece, thereby completing the fixing work.

[0030] The working principle of this utility model is as follows: When the corner-cutting device is needed to cut the corner of a workpiece, the workpiece is first placed on the worktable 1 and positioned at the correct angle. The corner to be cut is placed on the groove 201. After positioning, the workpiece needs to be fixed. At this time, the second electric push rod 302 is activated, causing the second electric push rod 302 to extend. The second electric push rod 302 drives the pressure plate 303 to descend, causing the pressure plate 303 to clamp and fix the workpiece, thus completing the fixing work. After fixing, the corner-cutting work can begin. At this time, the motor 210 drives the motor shaft 211 to rotate. The motor shaft 211 drives the rotating plate 212 to rotate. The rotating plate 212 drives the fixed shaft 213 to perform a circular motion. The fixed shaft 213 drives the moving plate 207 to perform a reciprocating motion through the fixing strip 208 on the moving plate 207. During the movement of the moving plate 207, the sliding of the slider 206 on the outer wall of the slide rail 205 allows the moving plate 207 to move in a reciprocating motion. 7. The movement is more stable and smooth. The moving plate 207 drives the connecting rod 214 to move repeatedly. The connecting rod 214 drives the cutter 215 to move repeatedly. Then, the first electric push rod 202 is activated, causing the first electric push rod 202 to extend. The first electric push rod 202 drives the lifting plate 203 to descend. The lifting plate 203 drives the cutter 215 to descend. While the cutter 215 moves back and forth repeatedly, it presses down and cooperates with the groove 201 to cut the corner of the workpiece, thereby completing the corner cutting work. When the cutter 215 has been used for a long time, the cutter 215 will become dull. At this time, the cutter 215 needs to be replaced. At this time, the nut 219 is rotated out from the outer wall of the threaded rod 217. Then, the locking block 218 on the cutter 215 is removed from the outer wall of the threaded rod 217. Then, the locking block 218 on the new cutter 215 is inserted into the outer wall of the threaded rod 217. Then, the nut 219 is rotated and inserted into the outer wall of the threaded rod 217 to fix the cutter 215, thereby completing the replacement work.
