Description

Technical Field

[0001] The invention relates to the technical field of water-ground stainless steel wire drawing abrasive cloth, in particular to processing equipment and a processing method for water-ground stainless steel wire drawing abrasive cloth. Background Art

[0002] Stainless steel wire drawing is a metal processing technology and the most popular surface treatment technology in the stainless steel and aluminum products industry today. It is a wire drawing effect treatment for stainless steel and aluminum products. In practical applications, stainless steel wire drawing is usually carried out using abrasive belts or emery cloth.

[0003] The existing patent announcement number CN203751532U discloses a sandpaper blanking laser cutting machine, which includes a glass platform arranged on the upper end surface of a frame, a front pressure roller arranged on the frame at the front end of the glass platform, an active pressure roller and a driven pressure roller arranged on the frame at the rear end of the glass platform, the active pressure roller and the driven pressure roller are arranged up and down, and rollers A and rollers B are arranged on the frames on both sides of the glass platform, and rollers A and rollers B are arranged with crossbeams, one end of the crossbeam is fixed on roller A, and the other end of the crossbeam is fixed on roller B. Two laser heads are arranged on the crossbeam, and the laser head can move left and right on the crossbeam driven by a motor, and the laser head is fixed on a laser head bracket, and a pressure bowl is arranged below the laser head bracket, the outer wall of the pressure bowl is arranged in a cone shape, and a through hole is arranged at the lower end of the pressure bowl, and the lower end of the laser head is arranged at the through hole at the lower end of the pressure bowl, and the crossbeam drives the laser head to move back and forth on rollers A and roller B.

[0004] In the above technical solution, when the sandpaper needs to be tensioned, the front pressure roller is pressed down by the cylinder to compress the sandpaper, and then the active pressure roller and the driven pressure roller rotate in opposite directions to tighten and flatten the sandpaper, and the laser head can start cutting. However, when the cutting is completed, the cut sandpaper loses the clamping limit of the front pressure roller, causing the sandpaper to loosen and be unable to be tensioned. In addition, since the sandpaper itself is of a relatively soft texture, the subsequent sandpaper cannot be stably transmitted to the front pressure roller, and the continuous cutting function of the sandpaper cannot be stably realized.

[0040] See also Figure 1-10 The present invention provides a technical solution: a processing device and a processing method for water-grinded stainless steel wire drawing sandpaper, comprising a conveyor belt 7, a supporting cavity 1, a stretching part, a laser cutting head 8 and a reel 5,

The unwinding roller 5 is arranged at the open end of the support cavity 1, and a transport roller group is rotatably connected to the inner side of the open end of the support cavity 1. A side plate 501 is rotatably connected to one side of the unwinding roller 5, and the side plate 501 is fixedly connected to the conveyor belt 7. The unwinding roller 5 is used to place the emery cloth roll 6 and unwind it to the inner side of the support cavity 1 through the transport roller group;

[0042] The stretching part is arranged inside the supporting cavity 1, and the stretching part includes a linear driving mechanism and a pair of clamping plates 101. The pair of clamping plates 101 are used to clamp the unwound abrasive cloth body, and the linear driving mechanism is used to drive the clamping plates 101 to move and pull out the abrasive cloth body of corresponding length. A blanking port 102 is opened at the lower side of the supporting cavity 1;

[0043] A movable seat 801 is provided at the upper end of the laser cutting head 8, and the movable seat 801 is driven to move by an electric telescopic rod 802. The laser cutting head 8 is arranged at the open end of the support cavity 1, and a slide groove is provided at the upper end of the support cavity 1. The laser cutting head 8 passes through the slide groove and moves along it, and the movable seat 801 slides at the upper end of the slide groove.

[0044] The emery cloth roll 6 is manually sleeved on the unwinding roller 5, and the emery cloth body is pulled out into the transport roller group, and the emery cloth body is transmitted to the support cavity 1 by the transport roller group, so as to realize the unwinding of the emery cloth roll 6; the unrolled emery cloth body enters the stretching part, a pair of clamps 101 clamp the head end of the emery cloth body, and the clamps 101 are driven to move by the linear drive mechanism, the emery cloth body is pulled out and cooperated with the transport roller group to tension it; at this time, the electric telescopic rod 802 drives the moving seat 801 and the laser cutting head 8 to move along the slide groove, and the laser cutting head 8 moves the tensioned emery cloth body. The cloth body is laser cut; after the cutting is completed, the cut sandpaper body is restricted by the transport roller group and will not be loosened, and then a pair of clamps 101 loosen the cut sandpaper body, and the sandpaper body can pass through the drop port 102 and fall onto the conveyor belt 7 for transportation, completing automatic unloading; then the pair of clamps 101 moves to reset, and re-clamps and pulls out the sandpaper body that has just been cut, and the laser cutting head 8 can cut the sandpaper body again, and this is repeated, thereby realizing continuous automatic slitting of the sandpaper roll 6, greatly improving work efficiency and strong stability;

[0045] Preferably, the clamping plate 101 is made of rubber material to further enhance the clamping stability.

[0046] The transport roller group includes a limiting roller 4 and a transmission roller 401. The limiting roller 4 and the transmission roller 401 are fitted and rolled against each other. A rotating rod 402 is arranged on the middle side of the transmission roller 401. Both ends of the rotating rod 402 are rotatably connected to the open end of the support cavity 1. A fixing rod 403 is arranged on the inner side of the limiting roller 4. Both ends of the fixing rod 403 are fixedly connected to the open end of the support cavity 1. A plurality of square grooves 404 are annularly provided on the middle side of the fixing rod 403. A plurality of spring telescopic rods 405 are arranged on the inner side of the square groove 404. An arc-shaped clamping tooth 406 is slidably fitted in the square groove 404. The spring telescopic rod 405 is connected to the arc-shaped clamping tooth 406. An annular clamping groove 407 is arranged on the inner side of the limiting roller 4. The annular clamping groove 407 and the arc-shaped clamping tooth 406 are engaged with each other.

[0047] Preferably, the limiting roller 4 and the transmission roller 401 are fitted and rolled with each other, so as to clamp and transport the emery cloth body, and in order to prevent the emery cloth body from rebounding to the emery cloth roll 6 after cutting, arc-shaped clamping teeth 406 and annular clamping grooves 407 are provided. Specifically, the annular clamping grooves 407 and the arc-shaped clamping teeth 406 are engaged with each other and can only rotate relative to each other in one direction. When the emery cloth body is pulled out, the limiting roller 4 and the transmission roller 401 rotate relative to each other. At this time, the fixed rod 403 is fixed, and the limiting roller 4 rotates relative to the fixed rod 403. The annular clamping grooves 407 contact the arc surface of the arc-shaped clamping teeth 406 and push them, so that the arc-shaped clamping teeth 406 are retracted into the square grooves 404 for evasion, and the rotation of the limiting roller 4 is not affected, so that the emery cloth body is normally transmitted;

[0048] When the emery cloth body is cut, the limiting roller 4 and the transmission roller 401 clamp the emery cloth body. At this time, the straight surface of the arc-shaped tooth 406 blocks the annular groove 407, so that the limiting roller 4 cannot be reversed, that is, the emery cloth body cannot rebound, thereby maintaining the current tension state and waiting for the next pulling work, with strong stability.

[0049] A pressing plate 103 is fixedly connected to the outside of the splint 101, and a spring telescopic rod 104 is arranged between the two ends of a pair of pressing plates 103. A concave frame 105 is slidably matched at both ends of the pressing plate 103. Vertical grooves are provided at the upper and lower ends of the middle side of the concave frame 105. An extension rod 107 is fixedly connected to the two ends of the pressing plate 103. The extension rod 107 passes through the vertical groove and moves along it. A pair of supporting columns 106 are fixedly connected to the outer end of the concave frame 105. Cover plates 112 are fixedly connected to the lower ends of the supporting columns 106 and the two ends of the concave frame 105. Guide grooves 108 are provided at the upper and lower ends of the inner sides of the supporting columns 106. The inner side of the guide groove 108 slides with a limiting block 109. The extension rod 107 passes through the limiting block 109 and is fixedly connected thereto. A winding wheel 110 is rotatably connected to the middle side of a pair of supporting columns 106. Connecting ropes 111 are provided at both ends of the winding wheel 110. A pair of connecting ropes 111 are respectively connected to the upper and lower limiting blocks 109.

[0050] Preferably, when the clamping plate 101 needs to be driven to clamp the head end of the emery cloth body, the winding wheel 110 is rotated to pull the connecting ropes 111 at both ends, so that the connecting ropes 111 are wound on the winding wheel 110, and the connecting ropes 111 pull the limit block 109 to move, and the limit block 109 moves along the guide groove 108 for guidance, thereby driving the extension rod 107 and the pressing plate 103 to move, so that the pair of clamping plates 101 can be brought close to each other and clamp the emery cloth body;

[0051] In contrast, when the clamping plates 101 need to be reset, the winding wheel 110 is reversed, and under the reset action of the spring telescopic rod 104, the pair of clamping plates 101 are pushed to reset, thereby loosening the emery cloth body.

[0052] The linear drive mechanism includes a pair of threaded rods 2, one end of the threaded rod 2 is rotatably connected to the support cavity 1, the threaded rod 2 is driven to rotate by the motor assembly, one end of the threaded rod 2 is threadedly connected to a threaded sleeve 201, one end of the threaded sleeve 201 is connected to the concave frame 105, and one end of the support column 106 is provided with a plurality of guide telescopic rods 202, which are connected to the support cavity 1.

[0053] Preferably, when it is necessary to drive the clamping plate 101 to pull out the emery cloth body, the threaded rod 2 is driven to rotate through the motor assembly, the threaded sleeve 201 is driven to move through the threaded connection, and the guide telescopic rod 202 is guided, so that the support column 106 and the concave frame 105 are displaced as a whole, and the emery cloth body can be pulled out.

[0054] One end of the winding wheel 110 close to the threaded sleeve 201 is fixedly connected with a connecting column 113, the connecting column 113 passes through the support column 106 and is rotatably connected thereto, one end of the connecting column 113 is fixedly connected with a gear 203, the threaded sleeve 201 extends to the interior of the concave frame 105 and is rotatably connected thereto, and one end of the threaded sleeve 201 is provided with an annular tooth groove 204, which meshes with the gear 203.

[0055] Preferably, in the initial state, the pair of clamps 101 are in the expanded state through the elastic support of the spring telescopic rod 2 104. At this time, the threaded rod 2 rotates to drive the threaded sleeve 201 to move, thereby driving the clamping plate 101 to move toward the open end of the supporting cavity 1, so that the head end of the emery cloth body enters the clamping range between the pair of clamping plates 101, and at this time the clamping plate 101 also moves to the open end of the supporting cavity 1 and cannot move further, that is, the threaded sleeve 201 cannot move. At this time, if the threaded rod 2 is continued to be driven to rotate, the threaded sleeve 201 is directly driven to rotate, and the annular tooth groove 204 is meshed with the gear 203 to drive the gear 203 and the connecting column 113 to rotate, which can drive the winding wheel 110 to rotate, so that the pair of clamping plates 101 clamp the emery cloth body. That is to say, the displacement of the driving clamping plate 101 can be achieved only by the rotation of the threaded rod 2, and then the driving clamping plate 101 clamps the emery cloth body. The two are connected in an orderly manner, and the degree of automation is high.

[0056] The supporting cavity 1 includes a pair of double-sided baffles 3, and a pair of mouth-shaped grooves are opened on the inner sides of the double-sided baffles 3. The mouth-shaped grooves include an expansion transverse groove 301, a clamping vertical groove 302, a clamping transverse groove 303 and a relaxation vertical groove 304. A center bar 307 is fixedly connected to the middle side of the mouth-shaped groove, and the extension rod 107 extends into the mouth-shaped groove and slides with it. Movable triangular wedge blocks 305 are arranged at both ends of the mouth-shaped groove, and a spring telescopic rod three 306 is arranged at one end of the triangular wedge block 305. The pair of triangular wedge blocks 305 are arranged oppositely, and the straight surfaces of the pair of triangular wedge blocks 305 are flush with the upper end surface and the lower end surface of the center bar 307 respectively. The extension rod 107 is restricted in the mouth-shaped groove and can only be displaced in the same direction.

[0057] Preferably, after the emery cloth body is clamped by the above embodiment, the reversal of the threaded rod 2 will cause the clamping plate 101 to directly loosen the emery cloth body and fail to drive the emery cloth body to be pulled out. Moreover, when the threaded sleeve 201 is driven to move, there is a certain probability that the clamping plate 101 is driven to clamp and move first, so that the clamping plate 101 is clamped before it moves to the position of the emery cloth body, resulting in an empty clamp. In order to further improve the stability of controlling the horizontal displacement and clamping action of the clamping plate 101 and facilitate driving the threaded sleeve 201 to reset and pull out the emery cloth body, a mouth-shaped groove is provided. Specifically, the extension rod 107 extends into the mouth-shaped groove, and the mouth-shaped groove limits and guides the displacement of the extension rod 107. The movement of the clamping plate 101 is restricted and guided. Specifically, when the threaded rod 2 drives the threaded sleeve 201 and the clamping plate 101 to move horizontally toward the open end of the supporting cavity 1, the extension rod 107 moves along the unfolding transverse groove 301, so that the clamping plate 101 is in the unfolded state and moves, thereby ensuring that the clamping plate 101 will not perform a clamping action in the middle, until it moves to the clamping vertical groove 302. At this time, the emery cloth body enters the clamping range of the clamping plate 101, and at this time, the clamping plate 101 and the threaded sleeve 201 can no longer move horizontally, and the threaded rod 2 continues to rotate, which can drive a pair of clamping plates 101 to clamp each other, and the extension rod 107 moves along the clamping vertical groove 302, along the inclined surface. The triangular wedge block 305 is pushed, and the triangular wedge block 305 is moved into the clamping transverse groove 303, and the emery cloth body can be clamped at this time. However, the extension rod 107 is also restricted in the clamping transverse groove 303 by the triangular wedge block 305, that is, the clamping plate 101 clamps the emery cloth body and cannot be loosened. At this time, the threaded rod 2 can rotate in the opposite direction, driving the threaded sleeve 201 to reverse synchronously, thereby driving the winding wheel 110 to release the connecting rope 111 first and reversely rewind it until it is rewound tightly, making it impossible for the winding wheel 110 to continue to reverse, that is, the threaded sleeve 201 can no longer reverse. At this time, the threaded rod 2 continues to reverse, which can drive the threaded sleeve 201 to move in the opposite direction and reset, driving the clamping plate 101 to pull out the emery cloth body, and extending the extension rod 107. The rod 107 is displaced along the clamping transverse groove 303 to the relaxing vertical groove 304, so that the emery cloth body can be completely pulled out and cutting can be carried out. After the cutting work is completed, the threaded rod 2 then drives the threaded sleeve 201 to rotate forward, thereby releasing the connecting rope 111. Under the resetting action of the spring telescopic rod 104, the splint 101 is unfolded and reset, and the extension rod 107 is displaced along the relaxing vertical groove 304 and passes through the triangular wedge block 305, thereby returning to the unfolding transverse groove 301, and the emery cloth body can be loosened to complete the unloading. Then the above steps can be repeated to start the next round of cutting function. In other words, the switching between the horizontal displacement and the clamping displacement of the splint 101 can be controlled only by the forward and reverse rotation of the threaded rod 2, and the stability is strong.

[0058] One end of the support cavity 1 passes through and is slidably fitted with a moving block 701, the outer end of the moving block 701 is fixedly connected to a support plate 702, a number of spring retraction rods 703 are arranged between the support plate 702 and the outer end of the support cavity 1, both ends of the rotating rod 402 extend into the inner side of the support cavity 1 and contact with the upper end surface of the moving block 701, and the moving block 701 corresponds to the concave frame 105.

[0059] Preferably, since the cut end of the emery cloth body is still at the laser cutting head 8 after cutting is completed, it is not within the clamping range when the clamp 101 is clamped again. Therefore, a moving block 701 is provided. Specifically, under the action of the spring retracting rod 703, the moving block 701 extends into the support cavity 1 in the initial state. When the clamp 101 completes unloading and moves toward the open end of the support cavity 1 again, the concave frame 105 pushes the moving block 701. The moving block 701 drives the rotating rod 402 to rotate through friction, which can drive the transmission roller 401 to rotate, thereby driving the emery cloth body to move a certain distance toward the direction of the clamp 101, thereby extending to the clamping range of the clamp 101, which is convenient for clamping. In other words, through the displacement of the clamp 101, the emery cloth body can be automatically fed, which is highly practical.

[0060] Annular bevel teeth 408 are provided at both ends of the rotating rod 402, and the lower end of the annular bevel teeth 408 is unidirectionally meshed with a bevel tooth row 409. An adaptation groove is provided on the upper side of the moving block 701, and the bevel tooth row 409 is slidably matched with the adaptation groove. A spring telescopic column 410 is provided between the bevel tooth row 409 and the adaptation groove.

[0061] Preferably, in order to improve the stability of the movable block 701 driving the rotating rod 402 to rotate and facilitate the automatic resetting of the movable block 701, a bevel tooth row 409 is provided. Specifically, when the concave frame 105 pushes the movable block 701, the bevel tooth row 409 engages with the annular bevel tooth 408, thereby driving the annular bevel tooth 408 to rotate, and the abrasive cloth body can be driven to feed automatically. When the movable block 701 needs to be reset, under the resetting action of the spring contraction rod 703, the inclined surface of the bevel tooth row 409 contacts the inclined surface of the annular bevel tooth 408, thereby driving the bevel tooth row 409 to sink into the adaptation groove for avoidance, and the movable block 701 can be reset, so as to facilitate the next feeding work.
