Description

Technical Field

[0001] This invention relates to the technical field of water-jet stainless steel wire drawing abrasive cloth, and more particularly to processing equipment and processing methods for water-jet stainless steel wire drawing abrasive cloth. Background Technology

[0002] Stainless steel wire drawing is a metal processing technique and one of the most popular surface treatment technologies in the stainless steel and aluminum products industry today. It is a wire drawing effect treatment applied to stainless steel and aluminum products. In practical applications, sanding belts or sandpaper are usually used for stainless steel wire drawing.

[0003] A sandpaper cutting laser cutting machine is disclosed in the existing patent publication number CN203751532U. It includes a glass platform mounted on the upper surface of the frame, a front pressure roller mounted on the front end of the glass platform, and an active pressure roller and a driven pressure roller mounted on the rear end of the glass platform. The active and driven pressure rollers are arranged vertically. Roller tracks A and B are mounted on the frames on both sides of the glass platform. A crossbeam is mounted on roller tracks A and B, with one end fixed to roller track A and the other end fixed to roller track B. Two laser heads are mounted on the crossbeams, and the laser heads can move left and right on the crossbeams driven by a motor. The laser heads are fixed to laser head supports, and a pressure bowl is mounted below the laser head supports. The outer wall of the pressure bowl is conical, and a through hole is provided at the bottom of the pressure bowl. The lower end of the laser head is located at the through hole at the bottom of the pressure bowl. The crossbeams drive the laser heads to move back and forth on roller tracks A and B.

[0004] In the above technical solution, when it is necessary to tighten the sandpaper, the front pressure roller is pressed down by the cylinder to tighten the sandpaper. Then the active pressure roller and the driven pressure roller rotate in opposite directions to pull the sandpaper tight and flat, so that the laser head can cut. However, after the cutting is completed, the cut sandpaper loses the pressure limit of the front pressure roller, causing the sandpaper to loosen and become unable to be tightened. Moreover, since the sandpaper itself is a relatively soft material, subsequent sandpaper cannot be stably transmitted to the front pressure roller, and the continuous cutting function of the sandpaper cannot be stably realized.

[0005] Therefore, it is necessary to provide processing equipment and processing methods for water-grinding stainless steel wire drawing abrasive cloth, which can achieve continuous slitting. Summary of the Invention

[0039] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0040] Please see Figure 1-10 The present invention provides a technical solution: a processing device and method for water-grinding stainless steel wire drawing abrasive cloth, comprising a conveyor belt 7, a support cavity 1, a stretching section, a laser cutting head 8, and an unwinding roller 5.

[0041] The support cavity 1 is located on the upper side of the conveyor belt 7. An opening is provided on one side of the support cavity 1. The unwinding roller 5 is located at the opening end of the support cavity 1. A transport roller group is rotatably connected to the inner side of the opening end of the support cavity 1. A side plate 501 is rotatably connected to one side of the unwinding roller 5. The side plate 501 is fixedly connected to the conveyor belt 7. The unwinding roller 5 is used to place the sandpaper roll 6 and unwind it to the inner side of the support cavity 1 through the transport roller group.

[0042] The stretching part is located inside the support cavity 1. The stretching part includes a linear drive mechanism and a pair of clamping plates 101. The pair of clamping plates 101 are used to clamp the unwound abrasive cloth body. The linear drive mechanism is used to drive the clamping plates 101 to move and pull out the abrasive cloth body of the corresponding length. A discharge port 102 is provided on the lower side of the support cavity 1.

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

[0044] The abrasive cloth roll 6 is manually attached to the unwinding roller 5, and the abrasive cloth body is pulled out into the transport roller group. The transport roller group then transfers the abrasive cloth body into the support cavity 1, thus unwinding the abrasive cloth roll 6. The unwound abrasive cloth body enters the stretching section, where a pair of clamping plates 101 clamp the head end of the abrasive cloth body. A linear drive mechanism drives the clamping plates 101 to move, pulling out the abrasive cloth body and cooperating 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. The laser cutting head 8 then applies pressure to the tensioned abrasive cloth. The cloth body is laser-cut; after the cutting is completed, the cut abrasive cloth body is restricted by the conveyor roller group and will not be released. Then, a pair of clamps 101 release the cut abrasive cloth body, and the abrasive cloth body can fall into the conveyor belt 7 through the discharge port 102 for transportation, completing automatic unloading; then the pair of clamps 101 move and reset, and clamp and pull out the abrasive cloth body that was just cut. The laser cutting head 8 can then cut the abrasive cloth body again. This process is repeated to achieve continuous automatic cutting of the abrasive cloth roll 6, which greatly improves work efficiency and stability.

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

[0046] The transport roller assembly includes a limiting roller 4 and a transmission roller 401. The limiting roller 4 and the transmission roller 401 roll in close contact with each other. A rotating rod 402 is provided on the middle side of the transmission roller 401. The two ends of the rotating rod 402 are rotatably connected to the open end of the support cavity 1. A fixing rod 403 is provided on the inner side of the limiting roller 4. The two ends of the fixing rod 403 are fixedly connected to the open end of the support cavity 1. Several square grooves 404 are circumferentially opened on the middle side of the fixing rod 403. Several spring telescopic rods 405 are provided on the inner side of the square grooves 404. Arc-shaped locking teeth 406 are slidably engaged in the square grooves 404. The spring telescopic rods 405 are connected to the arc-shaped locking teeth 406. An annular groove 407 is opened on the inner side of the limiting roller 4. The annular groove 407 and the arc-shaped locking teeth 406 are engaged with each other.

[0047] Preferably, the limiting roller 4 and the transmission roller 401 roll in close contact with each other to clamp and transport the abrasive cloth body. In order to prevent the abrasive cloth body from springing back to the abrasive cloth roll 6 after cutting, an arc-shaped locking tooth 406 and an annular locking groove 407 are provided. Specifically, the annular locking groove 407 and the arc-shaped locking tooth 406 engage with each other and can only rotate relative to each other in one direction. When the abrasive cloth body is pulled out, the limiting roller 4 and the transmission roller 401 rotate relative to each other. At this time, the fixing rod 403 remains stationary, and the limiting roller 4 rotates relative to the fixing rod 403. The annular locking groove 407 contacts the arc-shaped surface of the arc-shaped locking tooth 406 and pushes it, so that the arc-shaped locking tooth 406 retracts into the square groove 404 to avoid interference, without affecting the rotation of the limiting roller 4, thereby transporting the abrasive cloth body normally.

[0048] After the abrasive cloth body is cut, the limiting roller 4 and the transmission roller 401 clamp the abrasive cloth body. At this time, the straight surface of the arc-shaped tooth 406 jams the annular groove 407, so that the limiting roller 4 cannot reverse, that is, the abrasive cloth body cannot spring back, thus maintaining the current tension state and waiting for the next pull-out operation, with strong stability.

[0049] A pressure plate 103 is fixedly connected to the outer side of the clamping plate 101. A spring telescopic rod 104 is provided between the two ends of the pair of pressure plates 103. A concave frame 105 is slidably fitted to both ends of the pressure plate 103. Vertical grooves are opened at the upper and lower ends of the middle side of the concave frame 105. An extension rod 107 is fixedly connected to both ends of the pressure plate 103. The extension rod 107 passes through the vertical groove and moves along it. A pair of support columns 106 are fixedly connected to the outer end of the concave frame 105. A cover plate 112 is fixedly connected to the lower ends of the support columns 106 and the two ends of the concave frame 105. A guide groove 108 is opened at the upper and lower ends of the inner side of the support column 106. A limit block 109 is slidably fitted inside the guide groove 108. The extension rod 107 passes through the limit block 109 and is fixedly connected to it. A winding wheel 110 is rotatably connected to the middle side of the pair of support columns 106. A connecting rope 111 is provided at both ends of the winding wheel 110. The pair of connecting ropes 111 are respectively connected to the upper and lower limit blocks 109.

[0050] Preferably, when it is necessary to drive the clamping plate 101 to clamp the head end of the abrasive 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. The connecting ropes 111 pull the limiting block 109 to move, and the limiting block 109 moves along the guide groove 108 to guide it, thereby driving the extension rod 107 and the pressure plate 103 to move, so that the pair of clamping plates 101 can move closer to each other and clamp the abrasive cloth body.

[0051] Conversely, when the clamping plates 101 need to be reset, the winding wheel 110 reverses, and under the reset action of the spring telescopic rod 104, pushes the pair of clamping plates 101 to reset, thus loosening the abrasive cloth body.

[0052] The linear drive mechanism includes a pair of threaded rods 2, one end of which is rotatably connected to the support cavity 1. The threaded rods 2 are driven to rotate by a motor assembly. One end of the threaded rods 2 is threadedly connected to a threaded sleeve 201. One end of the threaded sleeve 201 is connected to a concave frame 105. One end of the support column 106 is provided with several 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 abrasive cloth body, the threaded rod 2 is driven to rotate by the motor assembly, the threaded sleeve 201 is driven to move by the threaded connection, and the guide telescopic rod 202 is guided, so that the support column 106 and the concave frame 105 are moved as a whole, and the abrasive cloth body can be pulled out.

[0054] A connecting post 113 is fixedly connected to one end of the take-up reel 110 near the threaded sleeve 201. The connecting post 113 passes through the support post 106 and is rotatably connected to it. A gear 203 is fixedly connected to one end of the connecting post 113. The threaded sleeve 201 extends into the interior of the concave frame 105 and is rotatably connected to it. An annular toothed groove 204 is provided at one end of the threaded sleeve 201. The annular toothed groove 204 meshes with the gear 203.

[0055] Preferably, in the initial state, the pair of clamping plates 101 are in an unfolded state due to the elastic support of the spring telescopic rod 104. At this time, the rotation of the threaded rod 2 drives the threaded sleeve 201 to move, thereby driving the clamping plate 101 to move towards the opening end of the support cavity 1, so that the head end of the abrasive cloth body enters the clamping range between the pair of clamping plates 101. At this time, the clamping plate 101 also moves to the opening end of the support cavity 1 and cannot move further, that is, the threaded sleeve 201 cannot move. If the threaded rod 2 is driven to rotate, it will directly drive the threaded sleeve 201 to rotate. Through the meshing connection of the annular tooth groove 204 with the gear 203, the gear 203 and the connecting column 113 will rotate, which will drive the winding wheel 110 to rotate, so that the pair of clamping plates 101 clamp the abrasive cloth body. In other words, the displacement of the clamping plate 101 can be achieved by only rotating the threaded rod 2, and then the clamping plate 101 will clamp the abrasive cloth body. The two are connected in an orderly manner, with a high degree of automation.

[0056] The supporting cavity 1 includes a pair of double-sided baffles 3. A pair of orifice grooves are provided on the inner side of the double-sided baffles 3. The orifice grooves include an unfolding horizontal groove 301, a clamping vertical groove 302, a clamping horizontal groove 303, and a relaxing vertical groove 304. A central bar 307 is fixedly connected to the middle side of the orifice groove. An extension rod 107 extends into the orifice groove and slides with it. Movable triangular wedges 305 are provided at both ends of the orifice groove. A spring telescopic rod 306 is provided at one end of the triangular wedges 305. A pair of triangular wedges 305 are arranged oppositely. The straight surfaces of the pair of triangular wedges 305 are flush with the upper and lower end surfaces of the central bar 307, respectively. The extension rod 107 is restricted to the orifice groove and can only move in the same direction.

[0057] Preferably, after the abrasive cloth body is clamped using the above embodiment, if the threaded rod 2 reverses, the clamping plate 101 will directly release the abrasive cloth body, and the abrasive cloth body cannot be pulled out. Furthermore, when driving the threaded sleeve 201 to move, there is a certain probability that the clamping plate 101 will clamp and move first, resulting in clamping before the clamping plate 101 reaches the position of the abrasive cloth body, causing an empty clamp. To further improve the stability of controlling the horizontal displacement of the clamping plate 101 and the clamping action, and to facilitate the reset movement of the threaded sleeve 201 to pull out the abrasive cloth body, a slot is provided. Specifically, the extension rod 107 extends into the slot, and the slot restricts 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 towards the opening of the support cavity 1, the extension rod 107 moves along the unfolding transverse groove 301, causing the clamping plate 101 to move in an unfolded state. This ensures that the clamping plate 101 will not clamp midway until it moves to the clamping vertical groove 302. At this point, the abrasive cloth body enters the clamping range of the clamping plate 101, and neither the clamping plate 101 nor the threaded sleeve 201 can continue to move horizontally. The threaded rod 2 continues to rotate, which drives the pair of clamping plates 101 to clamp each other. The extension rod 107 then moves along the clamping vertical groove 302 and along the inclined plane. Pushing the triangular wedge 305 moves the abrasive cloth body into the clamping groove 303, clamping it in place. However, the extension rod 107 is also confined within the clamping groove 303 by the triangular wedge 305, meaning the clamping plate 101 clamps the abrasive cloth body and prevents it from loosening. At this point, the threaded rod 2 rotates in the opposite direction, causing the threaded sleeve 201 to rotate synchronously in reverse. This drives the winding wheel 110 to first release the connecting rope 111 and then wind it in the opposite direction until it is tightly wound, preventing the winding wheel 110 from rotating in reverse. Consequently, the threaded sleeve 201 cannot rotate in reverse. When the threaded rod 2 continues to rotate in reverse, it drives the threaded sleeve 201 to move in the opposite direction and reset, causing the clamping plate 101 to pull out the abrasive cloth body, extending the extension rod 107. The rod 107 moves along the clamping horizontal groove 303 to the relaxation vertical groove 304, which can completely pull out the abrasive cloth body and make cutting possible. After the cutting is completed, the threaded rod 2 drives the threaded sleeve 201 to rotate forward, thereby releasing the connecting rope 111. Under the reset action of the spring telescopic rod 2 104, the clamping plate 101 unfolds and resets. The extension rod 107 moves along the relaxation vertical groove 304 and passes through the triangular wedge block 305, thereby returning to the unfolding horizontal groove 301, which can release the abrasive cloth body and complete the unloading. Then the above steps can be repeated to start the next round of cutting function. That is to say, the horizontal displacement and clamping displacement of the clamping plate 101 can be controlled by simply rotating the threaded rod 2, which has strong stability.

[0058] One end of the support cavity 1 is connected to a sliding block 701. The outer end of the sliding block 701 is fixedly connected to a support plate 702. Several spring retraction rods 703 are provided between the support plate 702 and the outer end of the support cavity 1. The two ends of the rotating rod 402 extend into the inner side of the support cavity 1 and contact the upper end surface of the sliding block 701. The sliding block 701 corresponds to the concave frame 105.

[0059] Preferably, since the cut end of the abrasive cloth body is still at the laser cutting head 8 after cutting, it is not within the clamping range when the clamping plate 101 clamps it again. Therefore, a moving block 701 is provided. Specifically, under the action of the spring retraction rod 703, the moving block 701 extends into the support cavity 1 in the initial state. When the clamping plate 101 finishes unloading and moves back to the opening end of the support cavity 1, the concave frame 105 pushes the moving block 701. The moving block 701 drives the rotating rod 402 to rotate through friction, which in turn drives the transmission roller 401 to rotate, thereby driving the abrasive cloth body to move a certain distance towards the clamping plate 101, thus extending into the clamping range of the clamping plate 101 for easy clamping. In other words, the automatic feeding of the abrasive cloth body is achieved through the displacement of the clamping plate 101, which is highly practical.

[0060] The rotating rod 402 has annular helical teeth 408 at both ends. The lower end of the annular helical teeth 408 is unidirectionally meshed with a helical tooth row 409. The upper side of the moving block 701 has an adaptation groove. The helical tooth row 409 slides with the adaptation groove. A spring telescopic column 410 is provided between the helical tooth row 409 and the adaptation groove.

[0061] Preferably, in order to improve the stability of the rotation of the moving block 701 driving the rotating rod 402 and to facilitate the automatic reset of the moving block 701, a helical tooth row 409 is provided. Specifically, when the concave frame 105 pushes the moving block 701, the helical tooth row 409 meshes with the annular helical tooth 408, thereby driving the annular helical tooth 408 to rotate, which can drive the abrasive cloth body to feed automatically. When the moving block 701 needs to be reset, under the reset action of the spring retraction rod 703, the inclined surface of the helical tooth row 409 contacts the inclined surface of the annular helical tooth 408, thereby driving the helical tooth row 409 to sink into the adaptation groove for avoidance, which can reset the moving block 701 and facilitate the next feeding operation.
