Description

Technical Field

[0001] This utility model relates to the technical field of filter production equipment, specifically a cutting device for processing air filter elements. Background Technology

[0002] The filter screen (metal mesh) in an air filter cartridge serves as a support structure for the filter paper, comprising an inner and outer filter screen. Its main functions are as follows: the metal mesh wraps around the outer and inner layers of the paper filter cartridge, providing rigid support to the filter paper through its mesh structure, preventing wrinkles and collapse due to airflow impact or vibration. For ease of transport, the metal mesh needs to be wound around a feed roller.

[0003] The existing technology includes an air filter element cutting device with publication number CN223071480U, comprising a table, base frames on both sides of the bottom of the table, a control console on one side of the front end of the bottom of the table, a groove on one side of the inside of the table, a frame on one side of the top of the table, a linear guide rail on the top of the inner side of the frame, a housing at the bottom end of the linear guide rail, a cutting mechanism inside the housing, a conveying mechanism at the bottom between the two ends of the groove, a limiting roller near the top between the two sides of the groove, an adjustment groove at the middle position of the top of the two ends of the groove, adjusting rods movably connected to both ends of the limiting rollers, one end of the adjusting rod penetrating the interior of the adjustment groove, fastening sleeves on the outside of the adjusting rods at both ends of the groove, and stabilizing components at the bottom of both sides of the housing.

[0004] When the above equipment is in use, the metal mesh fed by the feeding rollers curls up, making it difficult to accurately control the cutting length. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the aforementioned problems in the prior art, this utility model provides a cutting device for air filter processing, which can precisely control the cutting length and cut out the dimensions of the inner and outer filter screens.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] A cutting device for processing air filter elements includes a feeding mechanism located on the left side of a worktable, a conveying mechanism located to the right of the feeding mechanism, and a cutting mechanism located to the right of the conveying mechanism. The conveying mechanism includes a motor, a conveying roller, and a pressure roller. A driven wheel, connected to the conveying roller, is located on one side of the back of the worktable. A rotary encoder for detecting the number of rotations of the driven wheel is also located on one side of the back of the worktable. Adjustment mechanisms for adjusting the fixed height of the pressure roller are symmetrically arranged on the worktable. This device enables precise control of the cutting length, cutting out the dimensions of both inner and outer filter screens.

[0010] Preferably, the height adjustment mechanism includes a fixed frame, movable blocks, threaded rods and sliding rods, the pressure rollers are disposed between the movable blocks, and the fixed frame is also provided with locking bolts that cooperate with the movable blocks on its side wall.

[0011] Preferably, the cutting mechanism includes a mounting frame, a hydraulic cylinder, and a cutting blade.

[0012] Preferably, a guide roller is also provided between the feeding mechanism and the conveying mechanism.

[0013] (III) Beneficial Effects

[0014] This invention provides a cutting device for processing air filter elements. It has the following advantages:

[0015] (1) The rotary encoder rotates synchronously with the driven wheel on the conveyor roller. The rotary encoder generates pulse signals to the high-speed input port of the PLC for counting. Then, it calculates the length based on the set length of each pulse. When the preset length is reached, the PLC outputs a signal to stop the motor and start the cutting mechanism for cutting.

[0016] (2) Adjust the pressure of the conveying roller and the pressure roller on the metal mesh by adjusting the height adjustment mechanism to avoid slippage. Attached Figure Description

[0022] 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.

[0023] like Figure 1-4 As shown, the air filter cutting device of this embodiment includes a feeding mechanism 1 located on the left side of the worktable, a conveying mechanism 2 located on the right side of the feeding mechanism 1, and a cutting mechanism 3 located on the right side of the conveying mechanism 2. The conveying mechanism 2 includes a motor 201, a conveying roller 202, and a pressure roller 203. A driven wheel 4, which is connected to the conveying roller 202, is provided on one side of the back of the worktable. A rotary encoder 5 is also provided on one side of the back of the worktable to detect the number of rotations of the driven wheel 4, enabling precise control of the cutting length. A height adjustment mechanism 6 for adjusting the fixed height of the pressure roller 203 is also symmetrically arranged on the worktable. This allows adjustment of the squeezing pressure of the conveying roller and the pressure roller on the metal mesh.

[0024] Furthermore, the height adjustment mechanism 6 includes a fixed frame 601, a movable block 602, a threaded rod 603 and a slide rod 604, with pressure rollers 203 disposed between the movable blocks 602, and locking bolts 7 that cooperate with the movable blocks 602 are also provided on the side wall of the fixed frame 601.

[0025] Furthermore, the cutting mechanism 3 includes a mounting bracket 301, a hydraulic cylinder 302, and a cutting blade 303.

[0026] Furthermore, a guide roller 8 is also provided between the feeding mechanism 1 and the conveying mechanism 2.

[0027] Working principle: The metal mesh roll is fed by the feeding mechanism 1, and then synchronously conveyed by the conveying roller 202 and the pressure roller 203. During the conveying process, the driven wheel 4 on the conveying roller 202 drives the rotating wheel on the rotary encoder 5 to rotate synchronously. A high-speed counter (such as the HSC module of a PLC) collects the A / B phase pulse signals, records the total number of pulses, and then calculates the length. When the conveying length reaches the preset value, the controller stops the feeding mechanism 1 and the motor 201, and the cutting mechanism 3 performs the cutting. By setting the cutting length, the length of the inner and outer filter screens of the filter element can be cut.
