[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0048] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] This embodiment provides a dressing processing device, such as Figure 1-Figure 2 As shown, the dressing processing equipment includes a frame 1 and a material unwinding mechanism 4, a punching device 2, a slitting device 3 and a material receiving mechanism 5, all of which are arranged on the frame 1. The material unwinding mechanism 4 is used to unwind the material strip 6. The punching device 2 is used to punch holes in the material strip 6. The slitting device 3 is used to cut the material strip 6 into at least two strips along the width direction. The material receiving mechanism 5 is used to respectively rewind each cut material strip 6.

[0050] In the actual working process, the material strip 6 is wound through the unwinding mechanism 4, the punching device 2, the slitting device 3 and the receiving mechanism 5 in sequence. The unwinding mechanism 4 gradually releases the material strip 6. After the material strip 6 reaches the punching device 2, the punching device 2 performs a punching operation on the passed material strip 6 according to the preset punching parameters. After the material strip 6 moves to the slitting device 3, the slitting device 3 slits the punched material strip 6 according to the set slitting size, and the slit material strip 6 is transported to the receiving mechanism 5 for winding and sorting. The dressing processing equipment can realize punching and slitting on the same dressing processing equipment. During the overall processing, the material strip 6 only needs to be unwound and rewound once. The position of the material strip 6 only needs to be adjusted once to ensure the correct punching area, and the wide width material strip 6 can be slit into the required narrow width material strip 6. The whole process is simple, and the connection between each link is smooth, which improves production efficiency and reduces production cost and time cost.

[0051] like Figure 1-Figure 2 As shown, in this embodiment, the unloading mechanism 4 further includes two clamping rollers 46 and a conveying driving source (not shown in the figure), the two clamping rollers 46 are rotatably arranged on the frame 1, the two clamping rollers 46 are arranged downstream of the punching device 2 and upstream of the slitting device 3, and the material strip 6 is clamped between the two clamping rollers 46. When the conveying driving source drives at least one clamping roller 46 to rotate, the two clamping rollers 46 can stably convey the material strip 6 that has been punched, avoid the material strip 6 from being offset, loosened, etc. during the transmission process, and ensure the accuracy of subsequent slitting.

[0052] like Figure 1-Figure 2As shown, the slitting device 3 is arranged downstream of the punching device 2, and the material strip 6 moves to the slitting device 3 after being punched at the punching device 2. The whole roll of material strip 6 is punched first and then slit, and the tension and flatness of the material strip 6 during the punching are easier to control, which can avoid the problems of difficult positioning and difficult tension control when slitting first and then punching, and ensure that each slit material strip 6 can maintain a consistent punching effect, ensure that the punched holes are accurately positioned and have uniform hole diameters, and improve the reliability of the dressing processing equipment.

[0053] like Figure 1-Figure 2 As shown, the unloading mechanism 4 includes an unloading shaft 41, a magnetic powder brake 42 and a tension detection component 43. The unloading shaft 41 can rotate relative to the frame 1 and is used to carry the material strip 6. The output end of the magnetic powder brake 42 is connected to the unloading shaft 41, and can control the rotation speed of the unloading shaft 41, that is, control the unloading speed of the material strip 6. The tension detection component 43 can detect the tension of the material strip 6 and send a first signal, and the magnetic powder brake 42 can receive the first signal and adjust the rotation speed of the unloading shaft 41. On the one hand, when the tension of the material strip 6 changes, the tension detection component 43 sends a first signal, and the magnetic powder brake 42 adjusts according to the first signal to ensure that the tension of the material strip 6 is stable, avoid wrinkles and stretching deformation caused by uneven tension, and improve the reliability of the dressing processing equipment. On the other hand, the tension detection and speed adjustment are automatically completed, reducing manual intervention, improving production efficiency, reducing labor costs, ensuring the stability and efficiency of the unloading process, and laying a good foundation for subsequent processing procedures.

[0054] Specifically, in this embodiment, the tension detection assembly 43 includes a tension sensor 431 and three transition rollers 432. The three transition rollers 432 are arranged on the frame 1 at intervals along the conveying direction of the material belt 6. The material belt 6 is wound around the outer periphery of the three transition rollers 432 in sequence. Specifically, after the material belt 6 extends from the unwinding shaft 41, it is wound around the lower side of the first transition roller 432, and then it is wound around the upper side of the second transition roller 432, and then it is wound around the upper side of the third transition roller 432 and enters the punching device 2. The tension sensor 431 is a gravity sensor and is arranged between the second transition roller 432 and the frame 1. The first and third transition rollers 432 provide a guiding function for the material belt 6 so that the material belt 6 is fully in contact with the second transition roller 432. When the tension of the material belt 6 increases, the second transition roller 432 will be squeezed with a larger force, and the value detected by the gravity sensor will increase. On the contrary, when the tension of the material belt 6 decreases, the second transition roller 432 will be squeezed with a smaller force, and the value detected by the gravity sensor will decrease accordingly. The configuration of the three transition rollers 432 and the gravity sensor greatly enhances the sensitivity of tension adjustment.

[0055] like Figure 1-Figure 2As shown, the unloading mechanism 4 also includes a deviation correction component, which includes a deviation correction detection component (not shown) and an adjustment drive component (not shown). The deviation correction detection component can detect the axial position of the material belt 6 on the unloading shaft 41 and send a second signal. The output end of the adjustment drive component is connected to the unloading shaft 41, and the adjustment drive component can receive the second signal and drive the unloading shaft 41 to move along its axial direction. From the perspective of production accuracy, the monitoring of the position of the material belt 6 provides a reliable basis for subsequent precise adjustment. After receiving the second signal, the adjustment drive component can accurately drive the unloading shaft 41 to move along the axial direction, thereby correcting the position deviation of the material belt 6, ensuring that the material belt 6 is always in the preset running track, effectively improving the processing accuracy of the material belt 6, and improving the reliability of the dressing processing equipment. In terms of production stability, the automatic deviation correction function of the deviation correction component does not require frequent manual adjustment by humans, avoiding damage to the material belt 6 due to untimely or inaccurate human intervention, ensuring the continuity of processing, reducing the shutdown or failure of the dressing processing equipment caused by the deviation of the material belt 6 from the preset position, improving the operating efficiency of the dressing processing equipment, and reducing maintenance costs. Optionally, the deviation correction detection component can be a photoelectric sensor, an ultrasonic sensor, a visual sensor, an inductive sensor, etc., which is not specifically limited here.

[0056] like Figure 1-Figure 2 As shown, the correction component also includes a flat plate 45, and the unloading mechanism 4 also includes a unloading rack 44. The unloading shaft 41 is rotatably set on the unloading rack 44, and the unloading rack 44 is fixedly connected to the flat plate 45. The flat plate 45 is slidably connected to the frame 1 along the axial direction of the unloading shaft 41. The output end of the adjusting drive is connected to the flat plate 45. The adjusting drive can receive a second signal and drive the unloading rack 44 to move so that the unloading shaft 41 moves along its axial direction, and the position of the unloading shaft 41 is adjusted to keep the material belt 6 in the middle position of the unloading shaft 41.

[0057] Optionally, the adjusting drive member includes a servo motor, a screw and a nut, the servo motor is drivingly connected to the screw, the nut is sleeved on the screw and threadedly connected to the screw, and the nut is connected to the plate 45 to drive the plate 45 to reciprocate relative to the frame 1. The specific form of the adjusting drive member is not limited here.

[0058] like Figure 1As shown, the punching device 2 includes a puncher 21, a needle roller 22 and a first lifting assembly 23. The puncher 21 is provided with a die hole groove, the needle roller 22 is arranged below the puncher 21, and the needle roller 22 is provided with a protrusion that matches the die hole groove. The material strip 6 is wound around the needle roller 22, and the first lifting assembly 23 can drive the puncher 21 to lift and reciprocate, so that the die hole groove and the protrusion are plugged or separated, so as to punch a hole on the material strip 6 that matches the size and shape of the protrusion of the needle roller 22. On the one hand, the precise alignment design ensures that the punched holes are accurately positioned and uniform in size, meeting the strict requirements of the material strip 6 on the hole position and hole diameter, and improving the processing quality of the dressing processing equipment. On the other hand, the needle roller 22 rotates continuously, and the material strip 6 is continuously transported. At the same time, the puncher 21 performs lifting and reciprocating motion under the action of the first lifting assembly 23 to achieve continuous punching. Compared with the traditional intermittent punching method, the punching efficiency is greatly improved, which can meet the needs of large-scale production.

[0059] In this embodiment, the punching device 2 also includes a synchronous roller, a synchronous belt and a motor. The synchronous roller is rotatably arranged on the frame 1, and the synchronous belt is wound around the outer periphery of the synchronous roller and the needle roller 22, and the synchronous belt can be tensioned by the synchronous roller and the needle roller 22. The synchronous roller is transmission-connected to the output end of the motor, and the motor can drive the synchronous roller to rotate. The rotation of the synchronous roller drives the synchronous belt to move, and then drives the needle roller 22 to rotate synchronously.

[0060] In this embodiment, the puncher 21 is an ultrasonic puncher, which includes a mold, a transformer and a transducer. The transducer is connected to one end of the transformer by threaded connection or welding connection to ensure that the high-frequency vibration generated by the transducer can be effectively transmitted to the transformer. The other end of the transformer is connected to the mold by threaded connection, welding connection or fasteners. The transformer plays a role in amplifying the vibration amplitude output by the transducer. The transformer transmits the amplified vibration to the mold to provide the required energy for punching. A mold hole groove is provided on the mold, and the mold hole groove can be plugged in or separated with the protrusion on the needle roller 22 to achieve punching of the material strip 6.

[0061] like Figure 2 As shown, in this embodiment, five sets of ultrasonic punchers are provided in the dressing processing equipment, and the mold width in each set of ultrasonic punchers is 200 mm, which can punch holes in a material strip 6 with a width of 1000 mm at one time. In other embodiments, the number of ultrasonic punchers can also be one set, two sets, three sets, four sets, six sets, etc., which is not limited here.

[0062] In this embodiment, the first lifting assembly 23 is a slide cylinder, which includes a slide and a cylinder. The cylinder is disposed on the frame 1, and the slide is connected to the punch 21 through a connecting seat. The cylinder can drive the slide to reciprocate relative to the frame 1, thereby driving the punch 21 to reciprocate. This connection method ensures that the slide cylinder can provide stable linear motion power for the punch 21.

[0063] The actual working process of the punching device 2 is roughly as follows: when the dressing processing equipment is running, the motor drives the synchronous roller through the synchronous belt, and then drives the needle roller 22 to rotate, driving the material belt 6 to convey, and the cylinder pushes the slide to move relative to the frame 1, so that the ultrasonic puncher connected to the slide is lowered, and the ultrasonic puncher is started. The 20K ultrasonic energy is converted by the transducer and amplified by the amplitude rod and then transmitted to the mold. The mold hole groove on the mold cooperates with the protrusion on the needle roller 22 to complete the punching under the action of ultrasonic energy. During the whole process, various components work together to achieve efficient and accurate punching operation on the material belt 6.

[0064] like Figure 1 As shown, the slitting device 3 includes a roller 31 and a cutter assembly 32. The roller 31 is rotatably arranged on the frame 1. The material belt 6 is wound around the roller 31. The cutter assembly 32 is arranged above the roller 31 and can cut the material belt 6 into at least two strips along the width direction. The roller 31 is rotatably arranged on the frame 1. The material belt 6 can be continuously wound around the roller 31. The roller 31 can assist in supporting and conveying the material belt 6 to achieve uninterrupted conveying. The cutter assembly 32 located above the roller 31 can perform real-time slitting on the moving material belt 6. This continuous slitting working mode reduces the pause time in the production process, greatly improves the slitting efficiency, and meets the needs of large-scale production.

[0065] Specifically, Figure 1 As shown, the tool assembly 32 includes a slitting knife 321 and a knife holder 322, the knife holder 322 is connected to the frame 1, at least one slitting knife 321 can be installed on the knife holder 322, and the slitting knife 321 is arranged above the roller 31, and the material strip 6 is arranged between the slitting knife 321 and the roller 31, and the slitting knife 321 is used to cut the material strip 6 along the width direction. On the one hand, the knife holder 322 is connected to the frame 1, providing a stable support structure to ensure that the slitting knife 321 remains stable during operation. On the other hand, at least one slitting knife 321 can be installed on the knife holder 322, and by increasing, decreasing or adjusting the number and spacing of the slitting knives 321, different slitting requirements can be flexibly met, thereby improving the versatility of the equipment. Optionally, the number of slitting knives 321 can be one, two, three, four, five, six, etc., which are not specifically limited here.

[0066] In this embodiment, the slitting device 3 also includes a second lifting component (not shown), the output end of the second lifting component is connected to the slitting knife 321, and the second lifting component can drive the slitting knife 321 to move up and down and reciprocate. In the preparation stage, the slitting knife 321 can be lifted, which is convenient for the operator to place the material strip 6, without the need to thread the material in a small space or under the knife, reducing the difficulty of operation and safety risks. During operation, the second lifting component drives the slitting knife 321 to move up and down and reciprocate, which can effectively control the slitting force and depth, and is more adaptable to material strips 6 of different thicknesses and materials, ensuring the slitting accuracy and quality, and enhancing the flexibility of the equipment. When the slitting demand changes, by adjusting the lifting parameters of the slitting knife 321, the slitting mode can be quickly switched to improve the overall production efficiency and equipment practicality.

[0067] Optionally, the second lifting assembly includes a cylinder, a piston rod in the cylinder can reciprocate in the cylinder, the piston rod is connected to the slitting knife 321, and the lifting and lowering of the slitting knife 321 is realized. The specific form of the second lifting assembly is not limited here.

[0068] like Figure 1 As shown, in this embodiment, the dressing processing equipment further includes a composite roller assembly 47, which is arranged downstream of the slitting device 3. The composite roller assembly 47 includes a lower rubber roller 471, an upper eccentric rubber roller 472 and an upper mounting seat. The lower rubber roller 471 is rotatably mounted on the frame 1, and the upper eccentric rubber roller 472 is rotatably mounted on the upper mounting seat. The material strip 6 is sandwiched between the lower rubber roller 471 and the upper eccentric rubber roller 472. The upper mounting seat is movably connected to the frame 1 so as to be able to drive the upper eccentric rubber roller 472 to approach or move away from the lower rubber roller 471. Before the dressing processing equipment is operated, the upper eccentric rubber roller 472 is pre-pressed (i.e., the position of the upper eccentric rubber roller 472 relative to the lower rubber roller 471 is adjusted) to adjust the roller gap between the lower rubber roller 471 and the upper eccentric rubber roller 472 and squeeze the material strip 6, which can effectively adjust the thickness of the material strip 6, avoid unevenness around the hole after punching, and ensure the quality of the punching.

[0069] In this embodiment, the composite roller assembly 47 further includes a synchronous wheel, a transmission belt, a servo motor and a support. The lower rubber roller 471 and the upper eccentric rubber roller 472 are both rotatably mounted on the support. The support is fixedly connected to the frame 1. The synchronous wheel is rotatably arranged on the frame 1. The transmission belt is wound around the outer periphery of the synchronous wheel and the lower rubber roller 471, and the transmission belt can be tensioned by the synchronous wheel and the lower rubber roller 471. The output end of the servo motor is connected to the synchronous wheel. The servo motor can drive the synchronous wheel to rotate and drive the transmission belt to move, so that the synchronous wheel and the lower rubber roller 471 rotate synchronously, driving the material belt 6 sandwiched between the lower rubber roller 471 and the upper eccentric rubber roller 472 to move and transport, thereby enhancing the stability of the material belt 6 in the transmission between various processes. The composite roller assembly 47 further includes an eccentric handle. The output end of the eccentric handle is connected to the upper mounting seat. The eccentric handle can drive the upper eccentric rubber roller 472 to approach or move away from the lower rubber roller 471, so that the roller gap between the lower rubber roller 471 and the upper eccentric rubber roller 472 is adjustable, meeting the needs of high-quality dressing processing.

The cantilever sleeve 512 is rotatably connected to the frame 1 around a first axis extending in the vertical direction. The material receiving shaft 511 extends in the horizontal direction and the first end is rotatably connected to the cantilever sleeve 512. The driving source 513 is used to drive the material receiving shaft 511 to rotate to reel in the cut material strip 6. The first driving member 52 is mounted on the frame 1. The cantilever sleeve 512 is in driving connection with the output end of the first driving member 52. The first driving member 52 can drive the cantilever sleeve 512 to rotate relative to the frame 1, so that the second end of the material receiving shaft 511 can be rotatably overlapped on the frame 1 or away from the frame 1. When it is necessary to remove the cut material strip 6 on the receiving shaft 511, the cantilever sleeve 512 is driven to rotate around the frame 1 by means of the first driving member 52, and then the receiving shaft 511 is driven to rotate around the frame 1, and the receiving shaft 511 is separated from the frame 1, so that the cut material strip 6 can be removed from the second end of the receiving shaft 511. Compared with the conventional method of completely removing the entire receiving shaft 511 before removing the material strip 6 on the receiving shaft 511, it is greatly convenient for operators to unload the material strip 6, greatly shortens the material removal time, and improves efficiency. Optionally, the first driving member 52 can be a servo motor, a stepper motor, or a pneumatic motor, etc., which is not specifically limited here.

[0071] In addition, the driving source 513 can drive the receiving shaft 511 to rotate around the second axis A extending in the horizontal direction. During the winding process, the speed and torque of the receiving shaft 511 can be accurately adjusted according to the different characteristics of the material, thickness and slitting width of the material strip 6. For the thin and easy-to-stretch material strip 6, it can be wound at a lower and stable speed to ensure that the material strip 6 is evenly wound on the receiving shaft 511, which greatly improves the quality and accuracy of the winding. Optionally, the driving source 513 is a servo motor, a stepper motor or a pneumatic motor, etc., which is not specifically limited here.

[0072] like Figure 2 As shown, the cantilever sleeve 512 rotates around the first axis, and the operator can adjust the rotation angle of the receiving shaft 511 as needed. In this embodiment, the rotation angle of the receiving shaft 511 is 45 degrees. In other embodiments, the rotation angle of the receiving shaft 511 can be 30 degrees, 60 degrees, 75 degrees, 90 degrees, etc., which is not specifically limited here, as long as it is convenient for the operator to take the material.

[0073] In this embodiment, the receiving shaft 511 can be used to reel in one, two, three or more cut strips 6. The receiving mechanism 5 includes at least two cantilever assemblies 51, which are arranged at intervals in the vertical direction, so as to improve the compactness of the structure of the receiving mechanism 5, and the strips 6 on the two cantilever assemblies 51 can be reeled in without interfering with each other. In this embodiment, the receiving mechanism 5 includes at least two cantilever assemblies 51. For a dressing processing device that cuts the strip 6 into five strips, two strips 6 can be reeled in one receiving shaft 511, and three strips 6 can be reeled in the other receiving shaft 511.

[0074] Specifically, the material receiving shaft 511 can fix the positioning paper core, and the cut material strip 6 is wound on the positioning paper core. In this embodiment, the material receiving shaft 511 is an air-expanding shaft, and the positioning paper core is sleeved on the air-expanding shaft, and the air-expanding shaft can inflate and fix the positioning paper core. When the positioning paper core is sleeved on the air-expanding shaft, the air-expanding shaft can achieve a firm fixation of the positioning paper core by inflation, and the material strip 6 can be stably wound on the positioning paper core, ensuring that the positioning paper core will not become loose or offset during the winding process of the material strip 6, thereby ensuring the neatness and stability of the winding of the material strip 6 and improving the appearance quality of the material strip 6 after processing. In addition, the air-expanding shaft is easy to operate, and the inflation and deflation process is quick, which is convenient for the staff to quickly replace the positioning paper core after the material receiving is completed, thereby improving efficiency. When it is necessary to remove the positioning paper core, it is only necessary to deflate the air shaft. As the gas is slowly discharged, the outer diameter of the air shaft gradually shrinks, and the tight fit between the air shaft and the positioning paper core is released. The operator can easily remove the positioning paper core and the rolled material strip 6 from the air shaft. The whole process is simple and time-saving.

[0075] In other embodiments, the material receiving shaft 511 can also be a friction shaft, which automatically adjusts the winding tension by virtue of the friction characteristics between itself and the material strip 6, and can maintain a stable and appropriate tension at different stages of the winding of the material strip 6, thereby avoiding the material strip 6 from stretching and deforming due to excessive tension, or the material strip 6 from loosening due to insufficient tension. When receiving the material, the friction shaft can rotate in the opposite direction to adjust the tension of the material strip 6 after winding, thereby facilitating the removal of the material strip 6 and ensuring the winding quality.

[0076] like Figure 2 As shown, the material receiving mechanism 5 also includes a first gear 53 and a second gear 54, and the first gear 53 is connected to the first driving member 52 in a transmission manner, and the first driving member 52 can drive the first gear 53 to rotate. The second gear 54 is connected to the frame 1 in a rotation manner around the first axis, and the cantilever sleeve 512 is fixedly connected to the second gear 54, and the first gear 53 is meshed with the second gear 54. The first driving member 52 drives the first gear 53 to rotate, and the rotation of the first gear 53 drives the second gear 54 meshed therewith to rotate, and the cantilever sleeve 512 rotates relative to the frame 1, thereby driving the material receiving shaft 511 to rotate and move away from the frame 1. The gear transmission has a large torque transmission capacity and high transmission stability. In addition, the first gear 53 and the second gear 54 are arranged compactly, and efficient transmission is achieved in a limited space. The reasonable layout facilitates the installation and maintenance of each component, and improves the working stability of the dressing processing equipment.

[0077] In other embodiments, the material receiving mechanism 5 may also include a first synchronous wheel, a second synchronous wheel and a transmission belt, the first synchronous wheel is transmission-connected to the output end of the first driving member 52, the first driving member 52 can drive the first synchronous wheel to rotate, the second synchronous wheel is rotationally connected to the frame 1 around the first axis, the cantilever sleeve 512 is fixedly connected to the second synchronous wheel, the transmission belt is wound around the outer periphery of the first synchronous wheel and the second synchronous wheel, and the transmission belt can be tensioned by the first synchronous wheel and the second synchronous wheel, the first synchronous wheel rotates to drive the transmission belt to rotate, the transmission belt rotates to drive the second synchronous wheel to rotate, the cantilever sleeve 512 rotates relative to the frame 1, and then drives the material receiving shaft 511 to rotate and move away from the frame 1. Compared with gear transmission, the transmission belt generates less noise during operation, which helps to create a relatively quiet working environment.

[0078] like Figure 2-Figure 5As shown, the frame 1 includes a frame body 11, a mounting seat 12, a limiting chuck 13 and a first driving assembly 14. The mounting seat 12 is rotatably matched with the frame body 11 around a second axis A extending in the horizontal direction. The limiting chuck 13 is rotatably matched with the mounting seat 12 around a third axis B along the vertical direction. The limiting chuck 13 is provided with a limiting groove 131 on the side facing the cantilever assembly 51. The limiting groove 131 is used to limit the second end of the receiving shaft 511. The first driving assembly 14 is provided on the mounting seat 12. The first driving assembly 14 can drive the limiting chuck 13 to rotate from the first position to the second position or from the second position to the first position when the first driving member 52 drives the cantilever sleeve 512 to rotate. In the first position, the second end of the receiving shaft 511 is inserted into the limiting groove 131. In the second position, the second end of the receiving shaft 511 can be separated from the limiting groove 131 and away from the frame 1.

[0079] Specifically, when the limiting chuck 13 is in the first position, the second end of the receiving shaft 511 can be firmly inserted into the limiting chuck 13. When the driving source 513 drives the receiving shaft 511 to rotate to reel in the cut material strip 6, the limiting chuck 13 can rotate together with the receiving shaft 511, so that the receiving shaft 511 can always maintain a stable rotation state, avoiding the problem of uneven reeling of the material strip 6 due to the position deviation of the receiving shaft 511, thereby improving the reeling quality and ensuring the stability of the reeling process. When it is necessary to remove the reeled material strip 6 on the receiving shaft 511, the first driving member 52 drives the cantilever sleeve 512 to rotate relative to the frame 1, and at the same time, the first driving assembly 14 drives the limiting chuck 13 from the first position to the second position, and the second end of the receiving shaft 511 can easily detach from the limiting chuck 13 and move away from the frame 1, which greatly simplifies the loading and unloading process of the receiving shaft 511, improves the operating efficiency of the equipment, and improves the overall production efficiency.

[0080] like Figure 3-Figure 5 As shown, the frame 1 also includes a rotating bearing 15, which is arranged between the mounting seat 12 and the frame body 11, and the inner ring sleeve of the rotating bearing 15 is connected to the mounting seat 12, and the outer ring sleeve of the rotating bearing 15 is connected to the frame body 11, so that the mounting seat 12 rotates with the frame body 11 around the second axis A extending in the horizontal direction, so that when the receiving shaft 511 rotates around the second axis A extending in the horizontal direction during the receiving process, the limiting chuck 13 also rotates synchronously to ensure that the receiving shaft 511 rotates smoothly and steadily.

[0081] like Figure 3As shown, mounting holes are respectively provided at both ends of the limit chuck 13 along the vertical direction, and connecting columns 121 are respectively fixed at both ends of the mounting seat 12 along the vertical direction. Each connecting column 121 passes through a corresponding mounting hole, and a bearing is provided in the mounting hole. The outer ring sleeve of the bearing is connected to the inner wall of the mounting hole, and the inner ring sleeve of the bearing is connected to the connecting column 121, so that the limit chuck 13 can rotate from the first position to the second position or from the second position to the first position around the third axis B along the vertical direction.

[0082] In some embodiments, the first drive assembly 14 includes a linear drive member, which is mounted on the mounting seat 12, and the output end of the linear drive member is hinged to the eccentric position of the limit chuck 13, and the linear drive member can output a linear motion in the horizontal direction. This design structure is ingenious, converting the linear motion of the linear drive member in the horizontal direction into the rotation of the limit chuck 13 around the third axis B in the vertical direction, ensuring that the limit chuck 13 rotates in place in time, improving the consistency and efficiency of production operations, and providing strong support for the stable operation of the dressing processing equipment.

[0083] Specifically, Figure 3 As shown, the first driving assembly 14 includes a first cylinder 141 and a second cylinder 142, both of which are mounted on the mounting seat 12 and symmetrically arranged on both sides of the second axis A extending in the horizontal direction of the limiting chuck 13. One end of the first piston in the first cylinder 141 is hinged to one side of the limiting chuck 13. The second piston rod in the second cylinder 142 is hinged to the other side of the limiting chuck 13. When the limiting chuck 13 is in the first position, the first piston rod and the second piston rod both remain stationary. When the limiting chuck 13 is in the second position, the first piston rod extends and the second piston rod retracts. Through the targeted extension and retraction of the first piston rod and the second piston rod, the limiting chuck 13 can be accurately switched between the first position and the second position, and the limiting chuck 13 can be maintained in the first position or the second position.

[0084] like Figure 3 and Figure 5As shown, the limiting groove 131 includes a limiting portion 1311 and a guiding portion 1312, the limiting portion 1311 extends along the axial direction of the limiting chuck 13, the guiding portion 1312 extends radially from the side wall of the limiting portion 1311, and the depth of the guiding portion 1312 gradually decreases in the radially outward direction. When the limiting chuck 13 is in the second position, the second end of the receiving shaft 511 can enter the guiding portion 1312, the cantilever sleeve 512 rotates relative to the frame 1, and when the limiting groove 131 is synchronously rotated from the second position to the first position, the second end of the receiving shaft 511 can enter and be plugged into the limiting portion 1311 along the guiding portion 1312. On the one hand, the depth of the guiding portion 1312 gradually decreases in the radially outward direction, and the receiving shaft 511 can enter the limiting groove 131 more easily, which effectively reduces the collision between the receiving shaft 511 and the limiting chuck 13 during the rotation process, and prolongs the service life of the dressing processing device. On the other hand, the limiting portion 1311 ensures that the material receiving shaft 511 will not move during operation, thereby ensuring the stability and accuracy of the material receiving operation, thereby improving the material receiving quality of the product.

[0085] like Figure 1-Figure 2 As shown, the dressing processing equipment also includes a material taking device 7, which includes a second drive component 72 and a mechanical arm 71. The output end of the second drive component 72 is connected to the mechanical arm 71, and the second drive component 72 can drive the mechanical arm 71 to move along the material receiving shaft 511 to unload the material belt 6 wound on the material receiving shaft 511 from the second end of the material receiving shaft 511. The second drive component 72 of the material taking device 7 works in coordination with the mechanical arm 71, and can automatically unload the material belt 6 wound on the material receiving shaft 511 from the second end of the material receiving shaft 511, greatly reducing the time cost of manual unloading, allowing the equipment to quickly enter the next round of material receiving work, and greatly improving the overall production efficiency of the dressing processing equipment. In addition, the second drive component 72 of the material taking device 7 can accurately control the movement of the mechanical arm 71 along the material receiving shaft 511, ensuring that the unloading action is smooth and accurate, avoiding damage to the material belt 6, ensuring the quality of the material belt 6 after processing, and reducing the defective rate caused by improper unloading.

[0086] In this embodiment, the second drive component 72 can be a screw rod, a nut and a motor. The motor is connected to the screw rod in a transmission manner. The nut is sleeved on the screw rod and threadedly connected to the screw rod. The nut is connected to the mechanical arm 71 to drive the mechanical arm 71 to move along the receiving shaft 511. The second drive component 72 can also be a cylinder or a hydraulic cylinder, which is not specifically limited here.

[0087] In addition, in this embodiment, the second driving assembly 72 further includes a rotating driving member (not shown), the output end of which is connected to the mechanical arm 71, and the rotating driving member can drive the mechanical arm 71 to rotate, so that the mechanical arm 71 approaches and overlaps the receiving shaft 511, so as to remove the material belt 6 wound on the receiving shaft 511 from the second end of the receiving shaft 511. Optionally, the rotating driving member can be a servo motor, a stepping motor, etc., which is not specifically limited here.

[0088] like Figure 1-Figure 2 As shown, in this embodiment, the mechanical arm 71 is a U-shaped mechanical arm, and at least part of the material receiving shaft 511 can extend into the U-shaped opening of the U-shaped mechanical arm. The U-shaped mechanical arm moves along the material receiving shaft 511 to push the material belt 6 rolled up on the material receiving shaft 511 to be unloaded from the second end of the material receiving shaft 511, thereby reducing the difficulty and labor intensity of manual operation and improving the unloading efficiency. In other embodiments, the mechanical arm 71 can also be a rectangular mechanical arm, an arc-shaped mechanical arm, etc., which are not specifically limited here. In this embodiment, the material picking device 7 also includes a transport vehicle 73, which can receive and transport the rolled material belt 6 unloaded from the second end of the material receiving shaft 511, thereby reducing manual handling, improving efficiency, and making the dressing processing equipment work efficiently and orderly.

[0089] After the strip 6 is cut into multiple strips along the width direction, there will be waste materials with uneven thickness at both ends of the width direction. Figure 1 and Figure 2 As shown, the material receiving mechanism 5 also includes a waste receiving shaft 55 and a motor (not shown), the waste receiving shaft 55 extends in the horizontal direction and is rotatably connected to the frame 1, the output end of the motor is connected to the waste receiving shaft 55, the motor can drive the waste receiving shaft 55 to rotate around a fourth axis extending in the horizontal direction, and the waste receiving shaft 55 is used to receive waste with uneven thickness on both sides after cutting of the coiled material belt 6. It effectively solves the problem of waste disposal in the production process, avoids the messy production environment caused by the random scattering of waste, and facilitates the subsequent centralized treatment of waste, which is conducive to the standardization and neatness of the production process, and improves the orderliness and efficiency of the entire production system.

[0090] In this embodiment, the material collection mechanism 5 includes two waste collection shafts 55, which are respectively arranged on both sides of the frame 1, and can respectively roll up the waste with uneven thickness on both sides after the material strip 6 is cut. On the one hand, the waste collection shafts 55 distributed on both sides make full use of the space on both sides of the frame 1, avoiding the space congestion and waste chaos that may be caused by the concentration of waste in one place, making the layout of the entire production space more reasonable and orderly. On the other hand, the waste collection shafts 55 on both sides can roll up the waste at the same time, greatly improving the waste collection efficiency.
