Description

Technical Field

[0001] The invention relates to the technical field of filter component laser cutting, in particular to a filter component cutting device. Background Art

[0002] A filter is a device used to remove impurities from a fluid. The filter mesh, as an important component in the filter, is usually made of metal wire, plastic fiber, synthetic fiber and other materials. The filter mesh generally removes particulate impurities in the fluid by physical interception. In the prior art, the filter mesh is usually cut by laser cutting to facilitate subsequent secondary processing.

[0003] However, the traditional method of cutting the filter by laser has the following problems: 1. During the laser cutting of the filter, the necessary clamping limit is usually lacking near the cut portion of the filter, which causes the cut portion of the filter to easily warp and deform during the cutting process, resulting in poor stability and consistency of the cut surface when the filter is cut; 2. In the prior art, in order to avoid the loosening of the filter during the cutting process, usually only a single laser knife is used to gradually cut the entire filter. This cutting method results in a slow speed when cutting a larger area of ​​the filter, resulting in a low efficiency in the overall cutting process of the filter; 3. In the prior art, the laser knife uses a high-temperature melting method to cut the filter, which easily causes the cut portion of the filter to curl and deform due to large temperature changes, resulting in the corners of the cut filter product being unable to be effectively processed and utilized later, resulting in a certain degree of material waste and an increase in the overall production cost.

[0039] See also Figure 5 and Figure 6 The positioning assembly 53 includes a positioning plate 531, a positioning groove 532, a rotating frame 533, a positioning rod 534 and a positioning shaft 535; a positioning plate 531 is fixedly provided on the side of the U-shaped frame 523 away from the center of the return frame 421, a positioning groove 532 is provided on the side of the positioning plate 531 away from the U-shaped frame 523, the positioning groove 532 is composed of two asymmetric V-shaped grooves above and below and an oblique groove connecting the ends of the two V-shaped grooves, a rotating frame 533 is fixedly provided on the lower side of the return frame 421, located on the side of the positioning plate 531 away from the U-shaped frame 523, a positioning rod 534 is rotatably provided on the side of the rotating frame 533 close to the positioning plate 531, and a positioning shaft 535 slidably matched with the positioning groove 532 is fixedly provided on the upper end of the positioning rod 534.

[0040] When the driven roller 522 is at the initial highest position, the spring rod 1 521 always applies an upward elastic force to the driven roller 522 and the U-shaped frame 523 at the highest position, and under the action of the spring rod 1 521, the positioning plate 531 also keeps an upward movement trend synchronously with the U-shaped frame 523, and at the same time, the positioning shaft 535 at the upper end of the positioning rod 534 can also be stably engaged with the lowest point of the lower V-shaped groove in the positioning groove 532 (such as Figure 5 As shown in the front side), the U-shaped frame 523 and the positioning plate 531 can be stably located at the current position through the cooperation between the positioning rod 534 and the spring rod 521.

[0041] When the laser knife 433 on the connecting plate 431 is driven forward by the driving mechanism 6 to cut the filter screen 1, the trapezoidal blocks 434 on both sides of the connecting plate 431 move forward synchronously, and the inclined surface of the front end is rolled in contact with the adjacent driven roller 522 at the initial highest position of the front side, so that the driven roller 522 is continuously pressed downward until it contacts the lower surface of the trapezoidal block 434, and the driven roller 522 drives the U-shaped frame 523 and the positioning plate 531 to move downward to the lowest position synchronously through the spring rod 1 521. At this time, the positioning shaft 535 synchronously slides to the end of the front side of the upper V-shaped groove in the positioning groove 532 (such as Figure 5 As shown in the middle, during the continuous forward movement of the trapezoidal block 434, the lower surface of the trapezoidal block 434 can simultaneously press and limit the two adjacent driven rollers 522 to the lowest position.

[0042] As the trapezoidal block 434 continues to move forward, the driven roller 522 pressed to the lowest position begins to contact the inclined surface of the rear end of the trapezoidal block 434. Under the action of the spring rod 1 521, the driven roller 522 and the U-shaped frame 523 gradually move upward and return to a specific position below the initial highest position. At this time, the positioning shaft 535 slides to the lowest point of the upper V-shaped groove in the positioning groove 532 and is stably engaged with it (such as Figure 5 As shown in the rear side, the U-shaped frame 523 and the positioning plate 531 can be stably located at the current position through the cooperation between the positioning rod 534 and the spring rod 1 521.

[0043] When the laser knife 433 and the trapezoidal block 434 on the connecting plate 431 are driven by the driving mechanism 6 to move backward and reset, the trapezoidal block 434 will press the driven roller 522 at the specific position downward to the lowest point again. At this time, the positioning shaft 535 synchronously slides to the end of the rear side of the upper V-shaped groove in the positioning groove 532 until the trapezoidal block 434 and the driven roller 522 are disengaged again. At this time, the positioning shaft 535 slides again to the lowest point of the lower V-shaped groove in the positioning groove 532 and is stably engaged with it, so that the driven roller 522 and the U-shaped frame 523 can be reset to the initial highest position.

[0044] See also Figure 4and Figure 7 The driven component 54 includes a spring rod 541, a driven frame 542 and a straight groove 543; the horizontal section of the U-shaped frame 523 is symmetrically and elastically slidably provided with a spring rod 541, and the lower ends of the symmetrical spring rods 541 are fixedly provided with a driven frame 542, and the driven frame 542 is symmetrically provided with a straight groove 543 extending horizontally from left to right.

[0045] See also Figure 4 and Figure 7 The shaping component 55 includes a linkage frame 551, a guide rod 552, a driven shaft 553, a swivel seat 554 and a shaping roller 555; a linkage frame 551 that moves left and right is arranged at the lower side of the driven frame 542, and a guide rod 552 that is slidably connected to the driven frame 542 is symmetrically fixed front and back on one side of the linkage frame 551 away from the center of the return frame 421, and a driven shaft 553 that slides with the oblique groove 524 and the second straight groove 543 is symmetrically fixed on the front and rear sides of the linkage frame 551, and a swivel seat 554 is fixed at one end of the lower side of the linkage frame 551 close to the center of the return frame 421 through rod member 2, and a shaping roller 555 is rotatably arranged in the swivel seat 554.

[0046] In the process that the driven roller 522 is pressed from the initial highest position to the lowest position by the trapezoidal block 434, the driven roller 522 first drives the U-shaped frame 523 and the driven frame 542 to move downward synchronously through the spring rod 1 521, and the driven frame 542 then drives the linkage frame 551 and the shaping roller 555 to move downward synchronously until the shaping roller 555 contacts and presses the upper surface of the filter screen 1. At this time, the driven frame 542 and the linkage frame 551 can no longer move downward. 22 continues to move downward until it reaches the lowest position, the U-shaped frame 523 moves downward along the spring rod 2 541 and drives the driven shaft 553 to move along the straight groove 2 543 toward the end close to the laser knife 433 through the oblique groove 524, and the driven shaft 553 drives the connecting frame 551 and the shaping roller 555 to move synchronously to the end of the straight groove 2 543 close to the laser knife 433, thereby driving the shaping rollers 555 symmetrically distributed on the left and right to move synchronously toward each other in the direction close to the laser knife 433.

[0047] When the driven roller 522 detaches from the trapezoidal block 434 and resets to a specific position below the initial highest position, the U-shaped frame 523 synchronously moves upward to reset to a specific distance and cooperates with the driven shaft 553 through the oblique groove 524 to drive the shaping roller 555 to move horizontally and reset to the end of the straight groove 2 543 away from the laser knife 433. At this time, the shaping roller 555 still maintains a tight limit on the upper surface of the filter screen 1.

[0048] When the driven roller 522 at a specific position is pressed to the lowest point again by the trapezoidal block 434 that moves backward and resets, the U-shaped frame 523 then cooperates with the driven shaft 553 through the oblique groove 524 to drive the shaping roller 555 to move again to the end of the straight groove 2 543 close to the laser knife 433 until the trapezoidal block 434 and the driven roller 522 are separated again. At this time, the U-shaped frame 523 then drives the shaping roller 555 to move and reset to the initial height position.

[0049] See also Figure 3 The driving mechanism 6 includes a driving assembly 61 and a transmission assembly 62; the driving assembly 61 is symmetrically arranged on the upper side of the sliding guide rail 41, and the transmission assembly 62 is commonly arranged on the symmetrical driving assembly 61.

[0050] See also Figure 1 and Figure 3 The driving assembly 61 includes a fixing frame 611, a motor 612, a receiving seat 613 and a threaded rod 614; a fixing frame 611 is fixedly provided at the end of the front side of the sliding guide rail 41, a motor 612 is fixedly provided at the front side of the fixing frame 611, and a receiving seat 613 corresponding to the fixing frame 611 is fixedly provided at the end of the rear side of the sliding guide rail 41, and a threaded rod 614 fixedly connected to the driving end of the motor 612 is rotated between the receiving seat 613 and the fixing frame 611.

[0051] See also Figure 3 and Figure 4 The transmission assembly 62 includes a transmission plate 621, a linear groove three 622 and a sliding shaft two 623; the threaded rods 614 are symmetrical on the left and right, and the transmission plate 621 is threadedly connected together. The transmission plate 621 is provided with a linear groove three 622 extending horizontally from left to right. The rear end of the connecting plate 431 is fixed with a sliding shaft two 623 that slides with the linear groove three 622 through a plate one, and the cross-section of the sliding shaft two 623 is stepped.

[0052] When the laser knife 433 is driven to move forward to cut the filter 1, the electric push rod 432 is used to drive the laser knife 433 to move downward to a suitable cutting height, and then the motor 612 is used to drive the threaded rod 614 to rotate. The threaded rod 614 then drives the transmission plate 621 to move forward through the spiral transmission. The transmission plate 621 then drives the laser knife 433 on the connecting plate 431 to move forward through the sliding shaft 623 and laser cut the filter 1. At the same time, the trapezoidal block 434 that moves forward synchronously with the connecting plate 431 can press the driven roller 522 adjacent to the rear side of the laser knife 433 downward to the lowest point, so that the two left-right symmetrical shaping rollers 555 adjacent to the rear side of the laser knife 433 can always follow the cutting trajectory of the laser knife 433, first pressing down on the passing The surface of the filter 1 is then rolled toward each other to tighten the left and right symmetrical cut surfaces. This operation method can achieve fast and stable adaptive pressing and limiting of the filter 1 near the cut point along the cutting route of the laser knife 433, thereby avoiding the cut point of the filter 1 from warping and deformation and affecting the overall cutting process of the filter 1, thereby greatly improving the overall cutting stability of the filter 1 and the consistency of the cut surface. At the same time, through the cooperation of the positioning shaft 535 and the positioning groove 532, during the cutting process of the filter 1, all the shaping rollers 555 on the rear side of the laser knife 433 can always maintain the pressing and positioning near the cut point of the filter 1, thereby avoiding the cut part of the filter 1 from loosening due to pressing and affecting the overall cutting quality of the filter 1.

[0053] When the laser knife 433 and the trapezoidal block 434 are to be moved backward and reset, the laser knife 433 is first driven by the electric push rod 432 to move upward and reset to the initial position, thereby avoiding obstruction when the laser knife 433 moves backward, and then the motor 612 is reversed, thereby driving the connecting plate 431 to move backward and reset through the transmission plate 621, and the trapezoidal block 434 presses all the driven rollers 522 at specific positions to the lowest point again, so that all the left and right symmetrically distributed shaping rollers 555 move synchronously toward each other again in the direction close to the laser knife 433 and perform secondary rolling shaping near the cut-off point of the filter screen 1. This operation method solves the problem of curling deformation at the cut-off point of the filter screen 1 due to large temperature changes, so that the edges and corners of the finished product of the filter screen 1 can be effectively processed and utilized, reducing material waste in the production process and reducing the overall production cost.

[0054] When it is necessary to adjust the spacing between the cutting paths of each laser knife 433, the electric sliders 422 at both ends of the return frame 421 can drive the return frame 421 and the laser knife 433 to move horizontally synchronously and adjust to a suitable position, thereby adjusting the spacing between the cutting paths of each laser knife 433. The straight groove 424 can slide with the sliding shaft 435 to ensure that the connecting plate 431 can be stably adjusted horizontally. This operation method can quickly and stably adapt the area of ​​the filter screen cut product according to subsequent processing needs, thereby improving the application range of the cutting device.
