[0039] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Example:

[0041] The accompanying drawings show a specific embodiment of a wire drawing system for surface processing of a stainless steel plate according to the present invention. Figure 1 、 Figure 2 It mainly includes a frame 1, on which a feeding mechanism 2, a wire drawing processing mechanism 3, a pushing mechanism 4, an auxiliary feeding mechanism 5, and a discharging mechanism 6 are arranged from front to back.

[0042] The feeding mechanism 2 includes a feed belt 201, with two alignment wheels 202 and three air-blowing cleaning heads 203 on either side. Each alignment wheel 202 and each air-blowing cleaning head 203 are mounted on a common alignment frame 204, each of which is driven and moved by an alignment cylinder 205. Stainless steel sheet a is automatically fed via the feed belt 201. The alignment cylinder 205 drives the alignment frame 204 to synchronously extend the alignment wheels 202 and air-blowing cleaning heads 203. The alignment wheels 202 on either side can align and correct the deviation of the stainless steel sheet a to ensure feed consistency, while the air-blowing cleaning heads 203 can clean the stainless steel sheet a with air to remove surface impurities.

[0043] The rear side of the feed belt 201 is provided with an oblique groove 7, which is arranged downwardly and tilted from front to back. At the bottom of the oblique groove 7 are several equally spaced rollers 8, each of which is driven up and down by a first cylinder 11. The first cylinder 11 is mounted at the bottom of the frame 1. The output shaft of the first cylinder 11 is connected to a first bracket 12, on which the rollers 8 are rotatably mounted. The first bracket 12 and the rollers 8 are both located inside the frame 1. The first cylinder 11 drives the first bracket 12 to move the rollers 8 out of the oblique groove 7.

[0044] Multiple flexible support rollers 9 are arranged vertically within the inner wall at the rear end of the oblique groove 7. Each flexible support roller 9 is rotatably mounted on a second bracket 13. The second bracket 13 is driven back and forth by a second cylinder 14, which is mounted at the bottom of the frame 1. The second bracket 13 and the flexible support rollers 9 are both located within the frame 1. The second cylinder 14 drives the second bracket 13 to extend the flexible support rollers 9 into the oblique groove 7.

[0045] A retaining block 10 is provided within the inner wall of the front end of the oblique groove 7. The retaining block 10 is fixedly mounted on a third bracket 15. The third bracket 15 is driven forward and backward by a third cylinder 16. Two third cylinders 16 are provided, one mounted on each side of the frame 1, and the two third cylinders 16 are connected to the two ends of the third bracket 15. The third bracket 15 is installed through the frame 1, and the retaining block 10 is located inside the frame 1. The two third cylinders 16 can synchronously drive the third bracket 15 to drive the retaining block 10 into the oblique groove 7.

[0046] In this embodiment, the rear end surface of the pressing block 10 is an inclined surface, which is used to fit with the inclined end surface of the stainless steel plate a falling into the inclined groove 7, thereby achieving a better pressing and fixing effect on the plate.

[0047] A chip discharge port 17 is provided at the bottom of the frame 1, which is connected to the rear end of the inclined groove 7. The chips generated by processing can be discharged through the chip discharge port 17. The chip discharge port 17 can also be connected to a negative pressure adsorption device to help quickly clear chips.

[0048] The wire drawing mechanism 3 is arranged above the oblique groove 7, and is combined with Figure 1 、 Figure 2 、 Figure 3 The wire drawing mechanism 3 specifically includes a movable frame 301. A guide groove 18 is provided on both sides of the upper surface of the frame 1. The two bottom ends of the movable frame 301 pass through the two guide grooves 18 and are respectively mounted on the frame 1 via a first screw module. The first screw module is disposed inside the frame 1. The first screw module is driven by a motor to drive the movable frame 301 to move forward and backward, and the movable frame 301 can move along the guide groove 18. A turntable 302 is provided at the bottom of the movable frame 301. A first motor 305 connected to and driving the turntable 302 is provided at the top of the movable frame 301. A fourth cylinder 306 is provided at the bottom of the turntable 302. The fourth cylinder 306 is connected to the lifting frame 303 and drives the lifting frame 303 to move up and down. A wire drawing roller 304 is rotatably mounted at the bottom of the lifting frame 303. A rotating shaft 308 driven by a second motor 307 is provided at the top of the lifting frame 303. The two ends of the rotating shaft 308 are respectively connected to the two ends of the wire drawing roller 304 via a pulley assembly 309.

[0049] The wire drawing mechanism 3 is used to process the surface of stainless steel sheet a. The turntable 302 adjusts the angle of the wire drawing roller 304 to generate textures in different directions to suit different texture requirements. The movable frame 301 drives the wire drawing roller 304 back and forth, while the lifting frame 303 drives the wire drawing roller 304 up and down, bringing the wire drawing roller 304 into contact with the surface of stainless steel sheet a. Driven by a second motor 307, the rotating shaft 308 synchronously rotates the wire drawing roller 304 via two pulley assemblies 309 to process the stainless steel sheet a.

[0050] Furthermore, a pusher mechanism 4 is provided on one side of the oblique groove 7. The pusher mechanism 4 specifically comprises a second screw module 402 mounted on the frame 1 via a vertical frame 401, a crossbar 403 connected to the second screw module 402, and a vertical plate 404 connected to the crossbar 403. The length of the crossbar 403 is perpendicular to the conveying direction of the stainless steel plate a. The vertical plate 404 is connected to the bottom of the crossbar 403. The second screw module 402 is driven by a motor to drive the screw, which drives the crossbar 403 to move back and forth, thereby driving the vertical plate 404 to move back and forth, pushing out the processed stainless steel plate a.

[0051] The auxiliary feeding mechanism 5 includes a plurality of auxiliary feeding rollers 501 , which are evenly spaced and arranged on the frame 1 behind the inclined groove 7 . The stainless steel plate a can roll on the auxiliary feeding rollers 501 .

[0052] The discharging mechanism 6 includes a discharging belt 601 , which is arranged at the rear side of the auxiliary feeding roller 501 and is used for automatically discharging the stainless steel plate a.

[0053] In addition, a sensor A19 is provided on one side of the feed belt 201 , a sensor B 20 and a sensor C 21 are provided on the frame 1 at the front and rear ends of the inclined groove 7 , and a sensor D 22 is provided on one side of the discharge belt 601 .

[0054] When this embodiment is working, Figure 4 Stainless steel plate a is automatically fed through the feeding belt 201. After the sensor A19 detects the position of the plate, the alignment cylinders 205 on both sides respectively drive the alignment frames 204 on both sides to drive the alignment wheels 202 and the air cleaning heads 203 on both sides to extend synchronously. The alignment wheels 202 on both sides correct the deviation of the stainless steel plate a to ensure the consistency of the feeding. The air cleaning heads 203 on both sides blow air to clean the stainless steel plate a to remove surface impurities and achieve alignment and pre-cleaning. As the stainless steel plate a continues to be transported, as shown in FIG. Figure 5 , sensor B 20 detects the plate, the first cylinder 11 drives the front three rollers 8 to extend out of the inclined groove 7, the height of the three rollers 8 is the same as the height of the feed belt 201, and then the stainless steel plate a is sent to the rollers 8. Then sensor C 21 detects the position of the plate, as shown Figure 6 At this time, the second cylinder 14 drives the flexible support roller 9 to extend into the oblique groove 7 to prepare for the lowering of the stainless steel plate a. The flexible support roller 9 plays a buffering role. Then the three rollers 8 descend, and the stainless steel plate a falls into the oblique groove 7. Figure 7 As shown, after the stainless steel plate a completely falls into the inclined groove 7, the flexible support roller 9 retracts and returns to its original position, and the third cylinder 16 drives the pressing block 10 to extend into the inclined groove 7, fitting with the inclined end face of the stainless steel plate a, pressing and fixing the plate, and then the wire drawing processing mechanism 3 works, the moving frame 301 drives the wire drawing roller 304 to move back and forth, and the lifting frame 303 drives the wire drawing roller 304 to move up and down, so that the wire drawing roller 304 contacts the surface of the stainless steel plate a, and the wire drawing roller 304 rotates continuously to process along the surface of the stainless steel plate a. Figure 7 In the figure, the dotted line part indicates the end position of the drawing roller 304. The drawing roller 304 moves back and forth. After the plate processing is completed, the drawing processing mechanism 3 and the pressing block 10 are reset. Figure 8 As shown, the flexible support roller 9 and the roller 8 cooperate again to lift the stainless steel plate a. At this time, the four rollers 8 are all extended, and the stainless steel plate a moves upward along the flexible support roller 9 and completely escapes from the inclined groove 7. The height of the four rollers 8 is the same as the height of the auxiliary feed roller 501. Then the second screw module 402 drives the cross bar 403 to drive the vertical plate 404 to push the stainless steel plate a backward, as shown. Figure 9 As shown, the stainless steel plate a is pushed onto the auxiliary feed roller 501, and then the sensor D 22 detects the plate, and the discharge belt 601 starts to automatically output the stainless steel plate a, completing the plate processing. Figure 10 .
