[0003] The filter oil net includes feeding and unwinding, flattening, numerical control feeding and fixed length, shearing, discharging and other steps in the manufacturing and processing process, the filter oil net material is cut by the shearing machine, the shearing machine is usually a hydraulic or mechanical power guillotine shear. In the shearing step, when the filter oil net is transported to the preset length, the filter oil net stops and is clamped, the shearing machine starts, the upper blade of the guillotine shear falls quickly, and cooperates with the fixed lower knife seat to cut off the filter oil net. However, since the cutting surface of the net material is a discontinuous structure (from solid to hollow to solid), the impact force is uneven during shearing, burrs, silk hanging, uneven cut and accelerated tool wear are easily generated, replacement and maintenance of the tool need long time shutdown, affecting the production efficiency; secondly, the tiny metal chips generated by shearing are easily hung on the mesh and the tool surface, which is difficult to remove, affecting the cleanliness and appearance of the product, leading to the product quality to be improved, and the metal chips hung on the tool surface easily aggravate the tool wear, affecting the service life of the tool; furthermore, during long time cutting operation of the tool, the cutting position continuously rubs, leading to temperature rise, and thermal stress generated by repeated thermal fatigue will cause the tool edge to collapse, further affecting the cutting quality.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1 A range hood component manufacturing and processing equipment includes a shearing table 1. The shearing table 1 includes a support table and a lower blade holder installed in the middle of the top wall of the support table. A support mechanism 2 is symmetrically arranged on the shearing table 1. The support mechanism 2 changes position on the shearing table 1 by lateral translation. A blade changing mechanism 3, a shearing mechanism 4 and a chip removal mechanism 5 are provided on the support mechanism 2.

[0034] ReferenceFigure 1 and Figure 2 The tool changing mechanism 3 includes a shaft 31 mounted on the support mechanism 2, a bracket 32 ​​mounted on the shaft 31, and a loading and unloading assembly 33, a connecting assembly 34, and an upper blade 35 mounted on the bracket 32.

[0035] Reference Figure 1 , Figure 5 , Figure 7 and Figure 8 The chip removal mechanism 5 includes an L-shaped chip removal strip 51, a chip discharge hose 52, a chip pushing block 53, and a suction head 54, all mounted on the support mechanism 2.

[0036] The front side of the shearing table 1 is equipped with a material receiving and stacking device (not shown in the figure, existing mature equipment will not be described in detail here), and the rear side of the shearing table 1 is equipped with a leveling and fixed-length feeding device (not shown in the figure, existing mature equipment will not be described in detail here). The rolled filter oil screen is conveyed from back to front after passing through the leveling and fixed-length feeding device, and is sheared at the position of the lower blade holder at the top center of the shearing table 1.

[0037] During shearing operations, the L-shaped chip removal bar 51 is used to remove chips from the upper oil filter and the upper blade 35, while the chip pusher block 53 and the suction head 54 are used to remove chips from the lower blade holder. The chips are discharged through the chip discharge hose 52.

[0038] When the cutting tools need to be maintained or replaced, the shaft 31 and the bracket 32 ​​rotate to perform the up-and-down replacement of the cutting tools. The loading and unloading assembly 33, the connecting assembly 34 and the shearing mechanism 4 work together to quickly load, unload and replace the connecting assembly 34 and the upper blade 35, so that while one set of cutting tools is in use, the other set of cutting tools can be maintained without long-term downtime.

[0039] After a long period of shearing operation, the support mechanism 2 can change its position on the shearing table 1 by translation, which drives the blade changing mechanism 3, shearing mechanism 4 and chip removal mechanism 5 to change their positions, thereby changing the contact position between the upper blade 35 and the filter oil screen, thus performing intermittent alternation of the cutting position.

[0040] Reference Figure 1 and Figure 5The top wall of the shearing table 1 is provided with a slide rail oriented left and right. The support mechanism 2 includes an outer support seat 21, a middle support seat 23, and an inner support seat 24 that are slidably connected to the slide rail by an electric slider. An upper support seat 22 is fixedly connected to the side wall of the outer support seat 21. The upper support seat 22, the outer support seat 21, the middle support seat 23, and the inner support seat 24 are fixedly formed into a U-shaped structure. The outer support seat 21 is located away from the middle of the shearing table 1. The middle support seat 23 is fixedly connected to the side wall of the outer support seat 21 and is located directly below the upper support seat 22. The inner support seat 24 is fixedly connected to the side wall of the middle support seat 23 away from the outer support seat 21, close to the middle of the shearing table 1.

[0041] Reference Figure 1 , Figure 2 and Figure 5 A motor is installed inside the upper support seat 22 on the right side. A shaft 31 is fixedly installed on the left side wall of the motor output end. The left end of the shaft 31 is rotatably connected to the right side wall of the upper support seat 22 on the left side. A bracket 32 ​​is fixedly connected to the shaft 31 in a symmetrical manner.

[0042] Reference Figures 2 to 4 The loading and unloading assembly 33 includes a mounting groove 331. The upper and lower ends of the bracket 32 ​​are provided with mounting grooves 331. The upper and lower ends of the bracket 32 ​​are connected to the pushing block 333 by an electric slider. The upper and lower ends of the bracket 32 ​​are symmetrically arranged with the pushing block 333 as the center. The U-shaped limiting member 332 is slidably connected to the end of the bracket 32 ​​by a spring (not shown in the figure). The two horizontal sections of the U-shaped limiting member 332 are inclined on the side that is far apart from each other. The top wall of the pushing block 333 is formed by two opposing inclined surfaces forming an arrow shape. The inclined surface of the lower horizontal section of the U-shaped limiting member 332 is adapted to the inclined surface of the pushing block 333.

[0043] Reference Figures 2 to 4 The connecting component 34 includes a mounting base 341, with a mounting base 341 detachably mounted through the left and right corresponding mounting slots 331. Connecting bases 342 are symmetrically fixed at the left and right ends of the mounting base 341, and an upper blade 35 is detachably mounted on the mounting base 341.

[0044] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The shearing mechanism 4 includes a drive base 41. A hydraulic cylinder is mounted on the bottom wall of the upper support base 22. The drive base 41 is detachably mounted on the bottom wall of the output end of the hydraulic cylinder via a flange. A T-shaped locking block 46 is provided on the outer support base 21. The T-shaped locking block 46 includes a short section facing forward and backward and a long section facing left and right. A slot 343 adapted to the drive base 41 is opened in the middle of the connecting base 342. The connecting base 342 and the drive base 41 are provided with slots 443 that fit through the drive base 41 from left to right. The six long sections are fitted with mating holes 1 344 and 2 42; the top wall of the middle support 23 is provided with a sliding groove 1 43 for the drive seat 41 and the connecting seat 342 to slide up and down; the top wall of the inner support 24 is provided with a sliding groove 2 44 for the mounting seat 341 to slide up and down; the inside of the outer support 21 is provided with a sliding groove 3 45 for the T-shaped locking block 46 to slide up and down; the top of the sliding groove 3 45 is connected to a slot that penetrates the side wall of the outer support 21 and is used to insert the T-shaped locking block 46.

[0045] Reference Figure 5 , Figure 7 and Figure 8 On the side of the inner support base 24 on the left and right sides respectively, L-shaped chip removal strips 51 are symmetrically arranged front and back. The L-shaped chip removal strips 51 are driven to slide back and forth by an electric slider. The bottom wall (not shown in the figure) and side wall of the L-shaped chip removal strips 51 are provided with evenly distributed chip suction ports. The chip suction ports on the bottom wall are used for chip removal from the filter oil screen, and the chip suction ports on the side wall are used for chip removal from the surface of the upper blade 35 near the front and back sides. A chip pushing block 53 is fixed at the bottom of the inner support base 24 on the left side, and a suction head 54 is detachably installed at the bottom of the middle support base 23 on the right side. Both the chip pushing block 53 and the suction head 54 are set in the lower blade seat. The chip suction port and the chip discharge end of the suction head 54 are connected to the chip discharge hose 52.

[0046] When tool maintenance or replacement is required, the specific procedures are as follows: (e.g.) Figure 2 , Figure 5 As shown, the connecting assembly 34 and the upper blade 35 together form a loading and unloading module. This equipment has two loading and unloading modules. The output end of the motor rotates, driving the shaft 31 to rotate 180 degrees. The bracket 32 ​​then drives the two loading and unloading modules to alternate positions. The loading and unloading module installed on the upper side rotates to the lower side to dock and continue the shearing operation. The loading and unloading module to be maintained on the lower side rotates to the upper side for replacement and maintenance.

[0047] When replacing the loading and unloading module, the pushing block 333 at the upper end of the bracket 32 ​​slides upwards driven by the electric slider. The arrow-shaped top wall of the pushing block 333 gradually comes into contact with the inclined surface of the horizontal section of the pushing block 333, pushing the two U-shaped limiting members 332 opposite to each other away, so that the two U-shaped limiting members 332 opposite to each other move away from each other. Figure 3 The initial state shown changes to, for example Figure 4As shown, the U-shaped limiter 332 releases the lock on the mounting base 341, lifts the mounting base 341 upward, moves the mounting base 341 out of the mounting slot 331, and then performs maintenance on the upper blade 35; after maintenance is completed, the mounting base 341 is put back into the mounting slot 331, and the push block 333 slides down to reset by the drive of the electric slider, and the two U-shaped limiters 332 reset and move closer to each other, locking the maintenance-completed loading and unloading module.

[0048] It should be noted that the bracket 32 ​​is a detachable structure to facilitate the installation of the U-shaped limiter 332 and the pusher block 333; the upper blade 35 and the mounting base 341 are detachably connected by bolts, and the upper blade 35 is disassembled and replaced when it reaches the end of its service life.

[0049] When the loading and unloading module installed above rotates to the lower docking position, (such as...) Figure 2 , Figure 5 and Figure 6 As shown, the connecting seat 342 rotates between the middle support seat 23 and the upper support seat 22, and the drive seat 41 engages into the slot 343. The T-shaped locking block 46 is inserted into the slot of the outer support seat 21. The long section of the T-shaped locking block 46 is gradually inserted into the corresponding mating hole 344 in the connecting seat 342 and the mating hole 42 in the drive seat 41 until the short section of the T-shaped locking block 46 is completely inserted into the outer support seat 21.

[0050] The push block 333 at the lower end of the bracket 32 ​​slides downwards driven by the electric slider. The arrow-shaped top wall of the push block 333 gradually comes into contact with the inclined surface of the horizontal section of the push block 333, and pushes the two U-shaped limiting pieces 332 that are opposite each other away from each other, so that the two U-shaped limiting pieces 332 that are opposite each other release the locking of the mounting base 341.

[0051] This completes the docking process. The connecting component 34 and the upper blade 35 disengage from the loading / unloading component 33 and the bracket 32. The T-shaped locking block 46 connects the connecting seat 342 and the drive seat 41 into a whole. The hydraulic cylinder moves up and down reciprocally through its output end, driving the drive seat 41, the connecting component 34, and the upper blade 35 to move up and down reciprocally. The upper blade 35 is directly above the lower blade holder, and it cuts the filter screen below. During the up and down movement, the mounting groove 331 aligns vertically with the second slide groove 44. The mounting seat 341 slides down, disengaging from the mounting groove 331 and entering the second slide groove 44, sliding up and down. The connecting seat 342 and the drive seat 41 slide up and down in the first slide groove 43, and the T-shaped locking block 46 slides up and down in the third slide groove 45.

[0052] It should be noted that the top walls of the outer support 21, the middle support 23, and the inner support 24 are all concave arcs, and the bottom of the drive seat 41 is convex arcs to avoid interference with the loading and unloading of the module during rotation; a handle (not shown in the figure) can be detachably installed on the T-shaped locking block 46 for easy insertion and removal.

[0053] like Figure 5 , Figure 7 and Figure 8 As shown, during the shearing operation, the two L-shaped chip removal strips 51 slide closer to the sides of the upper blade 35 on the inner support seat 24 via an electric slider. The chip removal hose 52 is connected to an external suction pump (not shown in the figure). When the suction pump is started, the chip suction ports on the bottom wall of the two L-shaped chip removal strips 51 remove tiny metal chips from the surface and mesh of the filter oil screen, improving the cleanliness of the finished filter oil screen and enhancing product quality. The chip suction ports on the side wall of the two L-shaped chip removal strips 51 near the upper blade 35 remove tiny metal chips adhering to the surface of the upper blade 35 during shearing, preventing metal chips from sticking to the surface of the upper blade 35 and easily aggravating the wear of the upper blade 35, thus extending the service life of the tool. The suction head 54 sucks up the chips in the lower blade holder, and the chips sucked up by the L-shaped chip removal strips 51 and the suction head 54 are finally discharged through the chip removal hose 52.

[0054] After a prolonged continuous shearing operation, the machine is temporarily stopped. The electric slider drives the U-shaped structure, formed by the upper support 22, outer support 21, middle support 23, and inner support 24, to translate as a whole (from...). Figure 7 Change to Figure 8 In the initial state, the right side of the upper blade 35 shears the filter oil screen. When the position changes, the chip pusher 53 pushes the debris in the lower blade holder. After the position changes, the left side of the upper blade 35 shears the filter oil screen, and the suction head 54 continuously suctions, effectively removing debris from the blade holder and further protecting the upper blade 35 to reduce secondary wear. Changing the contact position between the upper blade 35 and the filter oil screen prevents the blade edge of the upper blade 35 from continuously rubbing against each other, which would cause the temperature to rise and avoid the thermal stress caused by repeated thermal fatigue, thus extending the service life of the upper blade 35.

[0055] In this invention, the tool changing mechanism 3 and the shearing mechanism 4 work together by rotating to perform alternating tool changing operations, facilitating quick replacement of the upper blade 35 and avoiding prolonged downtime for maintenance. The chip removal mechanism 5 is used to perform multi-directional chip removal operations on the front and rear sides of the upper blade 35, the surface and gaps of the filter mesh, and the interior of the lower tool holder during processing, improving the cleanliness of the finished oil filter and enhancing product quality. Simultaneously, it prevents wear on the upper blade 35 and extends the tool's service life. The left-right position change mechanism 2 is used to alternate the cutting position of the upper blade 35, changing the contact position between the upper blade 35 and the oil filter, preventing the upper blade 35 from continuously rubbing and heating up, which could lead to blade chipping. Although the tool changing mechanism 3, shearing mechanism 4, and chip removal mechanism 5 are added, increasing the cost of the equipment, the coordinated operation of these mechanisms not only improves the quality of shearing but also increases shearing efficiency. From a long-term economic perspective, the increased equipment cost of this invention compared to existing technologies is negligible.
