Description

Technical Field

[0001] The present invention belongs to the technical field of plastic coil forming, and particularly relates to a waterproof coil forming and processing device and method with multi-link drive and bidirectional clamping. Background Art

[0002] Due to its good waterproof performance and wide application range, waterproof coils have become an indispensable material in building waterproof projects. After being formed and processed, the waterproof coils form a specific plastic waterproof coil shape, which is widely used in the roof waterproofing of industrial and civil buildings, and can effectively prevent rainwater penetration and protect the building structure from water damage.

[0003] There are some deficiencies in the clamping mechanism of the forming and processing mechanism in the prior art. On the one hand, it is impossible to accurately control the clamping position and feeding process of the coil, resulting in the coil shifting or wrinkling during the processing, which affects the product quality. In the prior art, there is no effective solution for the dust and impurities on the surface of the coil, especially in the case where there are fine particles or electrostatic adsorption on the surface of the coil, and there are defects on the surface of the formed product, which affects the appearance and quality of the product.

[0004] On the other hand, the limit mechanism in the prior art cannot achieve accurate limit feeding of the coil, resulting in the coil shifting or jittering during the feeding process, which affects the stability of the forming process. The prior art cannot achieve accurate control of temperature, pressure, and forming time, resulting in low forming efficiency and unstable product quality.

[0005] In addition, the cutting mechanism in the prior art adopts mechanical cutting methods, such as blade cutting or punch cutting, etc. These methods often have low cutting accuracy and slow speed, and cannot meet the requirements of high-precision and high-speed cutting. The traditional material pushing mechanism relies on manual operation or simple mechanical structures and cannot automatically push out the cut product, resulting in uneven or damaged product pushing.

[0010] In the preferred embodiment, The bottom of the sliding clamp of the roller clamping assembly is connected to the support member through an electric lifting rod. A rotating shaft and a second clamping block are arranged in the support member, and one side of the rotating shaft is driven by a feeding motor.

[0011] In the preferred embodiment, A dust removal mechanism is installed on the top of the frame, and the dust removal mechanism includes an elastically lifting dust dusting plate, and the dust dusting plate realizes lifting and impacting action through the cooperation of the inclined surfaces of the first special-shaped block and the second special-shaped block.

[0012] In the preferred embodiment, A laser cutting assembly is arranged on the back side of the forming box, and the laser cutting assembly comprises a laser cutting knife driven by a multi-stage telescopic rod, and the cutting path of the laser cutting knife is aligned with the forming edge of the mold.

[0013] In the preferred embodiment, An automatic material pushing assembly is coaxially arranged on the back side of the forming box body, and the automatic material pushing assembly comprises a material pushing plate driven by a screw transmission mechanism, and the movement trajectory of the material pushing plate and the slide plate form a continuous material guiding channel.

[0014] In the preferred embodiment, A cylinder and several ejector rods are provided at the bottom of the mold of the hot pressing and forming assembly, and the ejector rods act synchronously with the hot pressing block to eject the formed product.

[0015] A forming and processing method for waterproof coiled materials includes the following steps: S1: Loading of the coiled material roll; Driven by the first servo motor, the multi-link transmission mechanism is linked, and the loading hook transfers the plastic waterproof coiled material roll into the interior of the second L-shaped plate; S2: Clamping and threading of the coiled material roll; Driven by the bidirectional threaded drive rod, the sliding clamps move towards each other, and the second clamping block is inserted into the card slot; S3: Adaptive limit feeding; Driven by the bevel gear set, the double lead screw lifting mechanism adjusts the distance between the limit pressure rollers, and cooperates with the feeding motor to drive the continuous feeding of the coiled material; S4: Dynamic dust removal; The inclined surfaces of the first special-shaped block and the second special-shaped block cooperate to trigger the impact dust removal of the dusting plate; S5: Hot pressing and forming; The hot pressing block and the mold cooperate to form, and the ejector rod ejects the product synchronously; S6: Cutting and pushing the material; Cut along the edge of the mold by the laser cutting knife, and the pushing plate exports the product through the sliding plate.

[0016] Compared with the prior art, the present invention provides a forming and processing equipment and method for waterproof coiled materials with multi-link transmission and bidirectional clamping, and has the following beneficial effects: The present invention adopts a multi-link transmission mechanism composed of a first connecting arm, a second connecting arm and a third connecting arm driven by a servo motor, and combines the articulated structure of a turntable and a triangular part to realize precise control of the movement trajectory of the loading hook. By triggering the multi-stage connecting arm linkage by the counterclockwise rotation of the turntable, the fifth connecting arm and the sixth connecting arm are driven to swing synchronously, ensuring the smooth transfer of the coiled material roll from the inclined plate at the storage position to the second L-shaped plate. This design replaces the traditional single-axis robotic arm through mechanical cooperation, eliminates redundant actions, and greatly improves the feeding efficiency and trajectory positioning accuracy.

[0017] A bidirectional threaded drive rod is arranged on the third connecting arm, and two groups of sliding clamps are driven to move towards each other synchronously by the second servo motor. Combining the clamping structure of the second clamping block and the card slot at the end of the coiled material roll, rapid clamping and centering positioning of the coiled material roll are realized. This clamping scheme avoids the material deviation caused by uneven pressure of the traditional clamping jaws, and effectively reduces the clamping positioning error.

[0018] The present invention drives the rotation of two groups of first lead screws synchronously through the meshing transmission of bevel gear sets, enabling the moving plate to drive the limiting pressure rollers to adaptively adjust the spacing and match the conveying requirements of coils with different thicknesses. This limiting mechanism combines with a feeding motor to drive the rotation of the coil roller, resulting in small fluctuations in material tension and significantly improved stability during the forming stage.

[0019] For the dust removal requirement, the inclined surfaces of the first special-shaped block and the second special-shaped block are used in cooperation. The contraction of the first spring provides the lifting power, and the release of the second spring triggers the rapid impact action of the dusting plate, achieving efficient dust removal on the surface of the coil. The mechanical elastic impact replaces the traditional pneumatic dust removal, reducing energy consumption and eliminating the secondary adsorption of dust caused by air flow disturbance, and improving the passing rate of surface cleanliness.

[0020] During the hot pressing and forming stage, the hot pressing block is driven by the first electric telescopic rod to be accurately aligned with the mold to complete the shaping of the coil; after forming, the cylinder drives the ejector rod to eject the finished product synchronously.

[0021] In the laser cutting stage, the multi-stage telescopic rod drives the laser cutting tool to cut along the path of the mold forming edge, and the flatness of the cut is improved through the control of the preset trajectory. The seamless connection between the hot pressing and cutting processes avoids the positioning error of traditional step-by-step processing.

[0022] The present invention integrates the timing control logic of feeding, clamping, limiting, dust removal, hot pressing, cutting, and pushing, forming a closed-loop production process. Through the coordinated control of multiple motors such as the first servo motor, transmission motor, and electric motor, unmanned continuous operation is achieved. The pushing plate and the sliding plate form a closed material guiding channel, ensuring the efficient export of the finished product without damage and reducing the system failure rate.

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art.

[0025] Please refer to Figures 1 - 12 As shown, a waterproof coiled material forming and processing device with multi-link transmission and bidirectional clamping of the present invention includes: Base 1, two groups of inclined plates 101 are fixedly connected to the left side of the base 1, the top ends of the two groups of inclined plates 101 are fixedly installed with a first L-shaped plate 102, a plastic waterproof coiled material roller 103 is arranged on the top of the first L-shaped plate 102, a frame 110 is installed in the middle of the top end of the base 1, a mounting plate 109 and a box body 112 are respectively arranged on both sides of the frame 110, a sliding plate 113 is installed on the outside of the box body 112, and two groups of guiding rollers 111 are installed on both sides of the frame 110; Feeding mechanism 2, which is fixedly installed on the top of the mounting plate 109 and is used to transfer the plastic waterproof coiled material roller 103; Clamping mechanism 3, which is arranged on the feeding mechanism 2 and is used to install the plastic waterproof coiled material roller 103; Dust removal mechanism 4, which is installed on the top of the frame 110 and is used to brush off the dust on the plastic coiled material; Limiting mechanism 5, which is arranged on the top of the box body 112 and is used to limit the conveying of the plastic coiled material; Blister forming mechanism 6, which is installed on the box body 112 and is used to perform blister forming on the plastic coiled material; Cutting mechanism 7, which is arranged on the back of the box body 112 and is used to cut off the formed blister product; Pushing mechanism 8, which is also installed on the back of the box body 112 and is used to push out the cut product.

[0026] Please refer to Figures 3 - 5As shown in the figure, the raw material of the present invention is a single-layer coil. The feeding mechanism 2 includes a first support bar 201. Both sides of the top end of the mounting plate 109 are welded with a first support bar 201, a second support bar 202, a third support bar 203, a fourth support bar 204 and a fifth support bar 205. The top of the first support bar 201 is rotatably connected with a first connecting arm 206. A rotating rod 208 is rotatably connected between two groups of third support bars 203. Both ends of the outer surface of the rotating rod 208 are fixedly connected with a turntable 209. A third connecting rod 220 is rotatably connected inside two groups of turntables 209. Both ends of the third connecting rod 220 are rotatably connected with a triangular member 210 and a fourth connecting arm 213. The other end of the first connecting arm 206 is rotatably connected with the middle part of the triangular member 210. And the inner side of the second support bar 202 is rotatably connected with a second connecting arm 207. A first connecting rod 211 is rotatably connected inside both sides of the second connecting arm 207. Both ends of the outer surface of the first connecting rod 211 are rotatably connected with a third connecting arm 212. The other end of the triangular member 210 is rotatably connected with the middle part of the third connecting arm 212. And the inner side of the fourth support bar 204 is rotatably connected with a sixth connecting arm 217. The other end of the sixth connecting arm 217 is rotatably connected with the fourth connecting arm 213. The outer side of the fifth support bar 205 is rotatably connected with a fifth connecting arm 216. The other end of the fifth connecting arm 216 is rotatably connected to the outside of the feeding hook 215. A second connecting rod 214 is rotatably connected inside both sides of the feeding hook 215. The other end of the fourth connecting arm 213 is rotatably connected to the outside of the second connecting rod 214. A first servo motor 218 is installed on the outside of the front third support bar 203. One end of the rotating rod 208 is fixedly connected to the output end of the first servo motor 218. And the tops of two groups of third connecting arms 212 are fixedly connected with a second L-shaped plate 219.

[0027] Please refer to Figure 2 As shown in the figure, clamping grooves 104 are opened at both ends of the plastic waterproofing coil 103. Mounting members 105 are installed at symmetric positions on the front and rear sides of the first L-shaped plate 102. An electric push rod 106 is fixedly connected to the outside of the mounting member 105. The output end of the electric push rod 106 is fixedly connected with a fixing plate 107. A first clamping block 108 adapted to the clamping groove 104 is fixedly connected to the inner side of the fixing plate 107.

[0028] In this solution, the working principle of the loading mechanism 2 is as follows: The output end of the first servo motor 218 drives the rotation of the rotating rod 208 and the two groups of turntables 209 as a whole, causing the triangular part 210 to rotate, driving the rotation of the first connecting arm 206, the second connecting arm 207, and the third connecting arm 212. At the same time, when the turntable 209 rotates, it drives the rotation of the fourth connecting arm 213, causing the fifth connecting arm 216 and the sixth connecting arm 217 to rotate. Therefore, when the output end of the first servo motor 218 drives the turntable 209 to rotate counterclockwise, the distance between the two groups of loading hooks 215 is greater than the width of the second L-shaped plate 219, and the loading hooks 215 can transfer the plastic waterproofing coil roll 103 into the second L-shaped plate 219. Moreover, the installation position of the clamping mechanism 3 is at the upper-middle part of the third connecting arm 212. This installation method of the clamping mechanism 3 will not interfere with the rotation and loading of the loading hooks 215.

[0029] After a set of plastic waterproofing coil rolls 103 are loaded, the previous plastic waterproofing coil roll 103 is clamped inside the first L-shaped plate 102. The clamping method is that the output end of the electric push rod 106 extends to drive the first blocks 108 on both sides to be stuck in the card slots 104 of the plastic waterproofing coil roll 103. The reason for doing this is that during the feeding of the subsequently loaded plastic waterproofing coil roll 103, the height of the plastic waterproofing coil roll 103 can also be changed by the loading mechanism 2, and the loading hooks 215 will no longer transfer the plastic waterproofing coil roll 103 into the second L-shaped plate 219. It also realizes the adjustment of the tension of the plastic during the conveying process, improving the ingenuity of the design.

[0030] Please refer to Figure 6 As shown, the clamping mechanism 3 includes a threaded rod 301, a guide rod 302, and a sliding clamp 305. The threaded rod 301 is rotatably connected inside the two groups of third connecting arms 212. The guide rod 302 is fixedly connected inside the two groups of third connecting arms 212. The thread directions of the two ends of the threaded rod 301 are opposite. And there are two groups of sliding clamps 305, which are respectively threadedly connected to the two ends of the outer surface of the threaded rod 301. An electric lifting rod 306 is installed at the bottom end of the sliding clamp 305. The output end of the electric lifting rod 306 penetrates the bottom wall of the sliding clamp 305 and is fixedly connected to the support member 307. A rotating shaft is rotatably connected inside the support member 307. Second blocks 309 are connected to the mutually approaching sides of the two rotating shafts. And a feeding motor 308 is installed on the outside of one of the support members 307. One end of one of the rotating shafts is fixedly connected to the output end of the feeding motor 308. And connecting members 303 are fixedly installed at both ends of the guide rod 302. The connecting members 303 are rotatably connected to the threaded rod 301. And a second servo motor 304 is installed on the outside of one of the connecting members 303. One end of the threaded rod 301 is fixedly connected to the output end of the second servo motor 304.

[0031] In this solution, the working principle of the clamping mechanism 3 is as follows: After the plastic waterproof coiled material roll 103 is transported into the inner part of the second L-shaped plate 219, the output end of the second servo motor 304 drives two sets of sliding clamps 305 to approach each other. The second clamping blocks 309 on both sides are stuck in the clamping grooves 104 at both ends of the plastic waterproof coiled material roll 103. Then, the output end of the electric lifting rod 306 drives the support member 307 to move upward to prevent the bottom supporting plate of the second L-shaped plate 219 from interfering with the feeding of the plastic waterproof coiled material roll 103. Finally, the output end of the feeding motor 308 drives the plastic waterproof coiled material roll 103 to rotate to achieve feeding.

[0032] Please refer to Figure 9 and Figure 10 As shown in the figure, the dust removal mechanism 4 includes a top plate 401. A track 402 and a chute 403 are provided on the top plate 401. The inner top end of the chute 403 is connected to a lifting plate 405 through a first spring 404. Limiting chutes are opened on both sides inside the chute 403. Both sides of the lifting plate 405 are slidably connected inside the limiting chutes. An installation groove 406 is provided on the lifting plate 405. A sliding member 407 is slidably connected inside the installation groove 406. One end of the sliding member 407 is fixedly installed with a limiting block 408, and the other end of the sliding member 407 is connected to a first special-shaped block 410. A second spring 409 is sleeved outside the sliding member 407. One end of the second spring 409 is fixedly connected to the inner wall of the installation groove 406, and the other end of the second spring 409 is fixedly connected to the outside of the first special-shaped block 410. A support plate 414 is fixedly connected to the lifting plate 405. Dusting plates 415 are installed at the bottom ends of the two support plates 414.

[0033] Please refer to Figure 10 As shown in the figure, a sliding member 412 is slidably connected inside the track 402. A welding rod 413 is fixedly installed on the sliding member 412, and a second special-shaped block 411 is also fixedly connected to the top plate 401.

[0034] In this solution, the working principle of the dust removal mechanism 4 is as follows: The track 402 drives the slider 412 and the welding rod 413 to move upward as a whole. The welding rod 413 supports the bottom of the first special-shaped block 410, causing the lifting plate 405 to also move upward. The first spring 404 is in a contracted state. When the inclined surface of the first special-shaped block 410 contacts the inclined surface of the second special-shaped block 411, the second spring 409 contracts, and the first special-shaped block 410 retracts into the installation groove 406. As a result, the welding rod 413 no longer supports the bottom of the first special-shaped block 410. Under the action of the first spring 404 restoring its deformation, the lifting plate 405 moves downward rapidly, and the dusting plate 415 pats the surface of the plastic downward, dusting off the dust remaining on the plastic surface to achieve dust removal. Then, the track 402 drives the slider 412 and the welding rod 413 to move downward as a whole. The welding rod 413 moves downward and contacts the inclined surface of the first special-shaped block 410, which can also cause the first special-shaped block 410 to retract into the installation groove 406, and the welding rod 413 can continue to move downward to the lower side of the first special-shaped block 410 to achieve the reset state.

[0035] Please refer to Figure 9 As shown, the limiting mechanism 5 includes a first fixing strip 501. Both sides of the top of the box body 112 are fixedly connected to the top seat 502 through the first fixing strip 501. A first lead screw 503 is rotatably connected between the top seat 502 and the box body 112. A moving plate 509 is threadedly connected to the first lead screw 503. The moving plate 509 is slidably connected to the first fixing strip 501, and a limiting pressure roller 510 is provided at the bottom of the moving plate 509. A first bevel gear 504 is installed at the top of the first lead screw 503. A support block 505 is fixedly connected to the top of the top seat 502. A rotating bar 506 is rotatably connected inside the two support blocks 505. A second bevel gear 507 meshing with the first bevel gear 504 is fixedly connected to the rotating bar 506. A transmission motor 508 is provided outside one of the support blocks 505, and one end of the rotating bar 506 is fixedly connected to the output end of the transmission motor 508.

[0036] In this solution, the output end of the transmission motor 508 drives the rotating bar 506 to rotate, causing the two second bevel gears 507 to rotate synchronously, driving the two first bevel gears 504 and the first lead screw 503 to rotate as a whole, causing the moving plates 509 on both sides to move downward synchronously, and thus the limiting pressure rollers 510 on both sides to move downward synchronously to limit the conveying of the plastic waterproofing membrane on the top of the box body 112.

[0037] Please refer to Figure 9 and Figure 10As shown in the figure, the thermoforming mechanism 6 includes a mold 601, which is fixedly installed inside the box body 112. A cylinder 602 is also fixedly connected to the inner bottom wall of the box body 112. The output end of the cylinder 602 is fixedly installed with a lifting member 603, and several groups of ejector rods 604 are arranged on the top of the lifting member 603. The ejector rods 604 extend into the mold 601. A first electric telescopic rod 605 is fixedly installed on the top of the box body 112, and the output end of the first electric telescopic rod 605 is fixedly connected to a hot pressing block 606.

[0038] In this solution, when the plastic waterproof coil reaches the top of the box body 112, the output end of the first electric telescopic rod 605 drives the hot pressing block 606 to move downward. The hot pressing block 606 and the mold 601 cooperate with each other to form a plastic product.

[0039] Please refer to Figure 11 As shown in the figure, the cutting mechanism 7 includes a welding seat 701, a multi-stage telescopic rod 702, and a laser cutting knife 703.

[0040] Please refer to Figure 12 As shown in the figure, the material pushing mechanism 8 includes two connecting blocks 801. Both of the two connecting blocks 801 are welded to the top of the base 1. A second fixing bar 803 is rotatably connected inside the two connecting blocks 801. A moving member 805 is slidably connected to the second fixing bar 803. A second lead screw 802 is rotatably connected between the two connecting blocks 801. The moving member 805 is threadedly connected to the second lead screw 802. A motor 804 for driving the second lead screw 802 to rotate is arranged on one of the connecting blocks 801. A second electric telescopic rod 806 is installed on the outside of the moving member 805, and the output end of the second electric telescopic rod 806 is fixedly connected to a material pushing plate 807.

[0041] In this solution, the laser cutting knife 703 is located directly above the left edge of the mold 601. Driven by the output end of the multi-stage telescopic rod 702, the laser cutting knife 703 moves to cut off the formed product. Then, the output end of the second electric telescopic rod 806 extends to drive the material pushing plate 807 to the top of the box body 112. Next, the output end of the motor 804 drives the second lead screw 802 to rotate, so that the moving member 805 moves to the right, driving the material pushing plate 807 to move to the right to push out the cut plastic product.

[0042] The following is a detailed description of the waterproof coil forming and processing method of the present invention. The specific steps are as follows: Step S1: Multi-link linkage feeding; Drive and transmission: Start the first servo motor 218, and its output end drives the rotating rod 208 to drive the two sets of rotating disks 209 to rotate counterclockwise synchronously; Linkage: The rotating disk 209 is hinged to the triangle 210 through the third connecting rod 220, driving the first connecting arm 206, the second connecting arm 207 and the third connecting arm 212 to swing; at the same time, the rotating disk 209 drives the fifth connecting arm 216 and the sixth connecting arm 217 to link through the fourth connecting arm 213; Coil transfer: When the turntable 209 rotates counterclockwise to a preset angle, the loading hook 215 swings with the fifth connecting arm 216 to accurately grab the plastic waterproof coil roll 103 on the inclined plate 101 and transfer it to the inside of the second L-shaped plate 219; Track control: The multi-link mechanism ensures that the movement track of the feeding hook 215 is aligned with the axis of the plastic waterproof coiled material roller 103 through mechanical limiting, so as to avoid collision or slipping during transportation.

[0043] Step S2: bidirectional thread clamping and threading; Clamping drive: start the second servo motor 304, and its output end drives the threaded rod 301 to rotate, so that the two sets of sliding clamps 305 move toward each other along the guide rail of the third connecting arm 212; Clamping and positioning: The rotating support 307 at the bottom of the sliding fixture 305 drives the second clamping block 309 to insert into the clamping grooves 104 at both ends of the plastic waterproof coiled material roller 103 to complete axial locking; Coil threading: The ends of the coil are passed through the guide rollers 111 on both sides of the frame 110 in sequence, and are pulled to the top platform of the forming box 112 to ensure that the center line of the coil coincides with the mold 601.

[0044] Step S3: bevel gear synchronous limiting and feeding; Limit adjustment: start the transmission motor 508, drive the rotating bar 506 to drive the two sets of second bevel gears 507 to rotate synchronously, and then drive the first screw rod 503 to rotate after meshing with the first bevel gear 504; Pressing roller downward: The first screw rod 503 drives the movable plate 509 to move vertically downward, so that the limiting pressing roller 510 presses the surface of the coil and automatically adjusts the spacing according to the thickness of the coil. The adjustment range is: 0.5-3mm; Continuous feeding: The feeding motor 308 is started synchronously to drive the rotating shaft of the rotating support 307 to drive the plastic waterproofing roll 103 to rotate at a constant speed, and the roll is transported to the forming station at a constant tension through the guide roller 111.

[0045] Step S4: special-shaped block triggered impact dust removal; Lifting trigger: the track 402 drives the sliding member 412 to drive the welding rod 413 to rise, lift the bottom of the first special-shaped block 410, and make the lifting plate 405 compress the first spring 404 and move upward; Bevel unlocking: When the bevel surface of the first special-shaped block 410 contacts the second special-shaped block 411, the second spring 409 is compressed and contracted, the first special-shaped block 410 retracts into the mounting groove 406, and the welding rod 413 disengages from its support. Impact dust removal: The first spring 404 quickly resets, driving the lifting plate 405 to drive the dusting plate 415 to punch downward, patting the surface of the coil at a frequency ≥ 20 times / minute to remove the dust adsorbed by static electricity, and the dust removal efficiency ≥ 95%.

[0046] Step S5: Hot pressing and ejecting; Hot pressing and shaping: The first electric telescopic rod 605 drives the hot pressing block 606 to press down into the cavity of the mold 601, and hot pressing and shaping are carried out under the conditions of a temperature of 180 - 220 °C and a pressure of 5 - 8 MPa. Ejecting and demolding: After shaping, the cylinder 602 drives the ejector rod 604 to eject the workpiece synchronously, and the ejection stroke is linked with the return stroke of the hot pressing block 606 to avoid product deformation.

[0047] Step S6: Laser cutting and pushing and guiding; Precision cutting: The multi-stage telescopic rod 702 drives the laser cutting knife 703 to move along the left edge path of the mold 601, and cutting is completed under a laser power of 800 - 1200 W, with the burr of the cutting edge ≤ 0.05 mm. Pushing and discharging: The second electric telescopic rod 806 extends, driving the pushing plate 807 to rise to be flush with the top of the forming box body 112. The motor 804 drives the second lead screw 802 to rotate, driving the moving part 805 and the pushing plate 807 to move rightward, and the cut product is exported to the collection area through the slide plate 113. After the pushing plate 807 resets, the system automatically enters the next production cycle.

[0048] The present invention realizes unmanned continuous production of feeding - clamping - limiting - dust removal - forming - cutting - pushing through multi-motor collaborative control of the first servo motor 218, transmission motor 508, etc., and the production efficiency is increased to 20 - 25 pieces / hour. The positioning error of the multi-link feeding mechanism ≤ ±0.3 mm; the self-adaptive adjustment of the limiting roller 510 makes the coil tension fluctuation ≤ ±3%; the alignment accuracy between the laser cutting path and the mold edge reaches ±0.1 mm. The mechanical dust removal reduces the energy consumption by 50% compared with the pneumatic dust removal; the service life of the bidirectional threaded clamping component ≥ 100,000 cycle times, and the failure rate < 0.3%.
