Description

Technical Field

[0001] The present invention relates to the technical field of dressing production equipment, in particular to dressing processing equipment. Background Art

[0002] In the medical dressing industry, silicone gel dressing is a medical product that can help wounds heal. Because silicone gel needs to be breathable during application, it needs to be processed.

[0003] At present, the processing process of wide-width silicone gel dressing tape is roughly as follows: first, the tape is placed on the slitting equipment, and the tape is cut into narrow-width tapes by the slitting tool. After the slitting is completed, the slit narrow-width tape is reeled up, and the reeled narrow-width tape is manually transported to the punching equipment. The narrow-width tape is placed in the unloading mechanism of the punching equipment for unloading. The puncher punches the narrow-width tape to make holes that evenly meet the specific size and spacing requirements. After the punching is completed, the punched narrow-width tape is reeled up. In the above process, the process of transporting the narrow-width tape from the slitting equipment to the punching equipment is not only manpower-consuming, but may also cause damage or contamination to the tape. In addition, the slitting and punching processes of the tape require the unwinding, alignment adjustment, and rewinding of the tape respectively. The entire process is complicated and the connection between the various links is not smooth, which seriously restricts the improvement of production efficiency and increases production costs and time costs.

[0004] Therefore, a dressing processing equipment is urgently needed to solve the above problems. Summary of the Invention

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[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 feeder mechanism 4, a punching device 2, a slitting device 3, and a rewinding mechanism 5, all mounted on the frame 1. The feeder mechanism 4 is used to feed a rolled 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 its width. The rewinding mechanism 5 is used to rewind each cut strip of material strip 6.

[0050] During the actual operation, 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. 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 cut the wide width material strip 6 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 unwinding mechanism 4 further includes two pinch rollers 46 and a conveyor drive source (not shown). The two pinch rollers 46 are rotatably mounted on the frame 1, downstream of the punching device 2 and upstream of the slitting device 3. The material strip 6 is clamped between the two pinch rollers 46. When the conveyor drive source drives at least one of the pinch rollers 46 to rotate, the two pinch rollers 46 can stably convey the punched material strip 6, preventing the material strip 6 from deflecting or loosening during transport, thereby ensuring the accuracy of subsequent slitting.

[0052] like Figure 1-Figure 2As shown, the slitting device 3 is disposed downstream of the punching device 2. After being punched at the punching device 2, the material strip 6 moves to the slitting device 3. The entire roll of material strip 6 is punched first and then slit. This makes it easier to control the tension and flatness of the material strip 6 during punching, avoiding the problems of positioning difficulties and tension control encountered when slitting first and then punching. This ensures that each slit of the material strip 6 maintains a consistent punching effect, ensuring precise hole positioning and uniform hole diameter, and improving 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 assembly 43. The unloading shaft 41 is rotatable 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, the unloading speed of the material strip 6. The tension detection assembly 43 detects the tension of the material strip 6 and sends a first signal. The magnetic powder brake 42 receives the first signal and adjusts the rotation speed of the unloading shaft 41. On the one hand, when the tension of the material strip 6 changes, the tension detection assembly 43 sends a first signal, and the magnetic powder brake 42 adjusts according to the first signal, ensuring stable tension of the material strip 6, avoiding wrinkles and stretching deformation caused by uneven tension, and improving the reliability of the dressing processing equipment. On the other hand, tension detection and speed adjustment are completed automatically, reducing manual intervention, improving production efficiency, and lowering labor costs. This ensures a stable and efficient unloading process, laying a good foundation for subsequent processing steps.

[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 spaced apart on the frame 1 along the conveying direction of the material strip 6. The material strip 6 is sequentially wound around the outer circumferences of the three transition rollers 432. Specifically, after extending from the unwinding shaft 41, the material strip 6 is wound around the lower side of the first transition roller 432, the upper side of the second transition roller 432, and the upper side of the third transition roller 432 before entering the punching device 2. The tension sensor 431 is a gravity sensor and is positioned between the second transition roller 432 and the frame 1. The first and third transition rollers 432 provide guidance for the material strip 6, ensuring that the material strip 6 is in full contact with the second transition roller 432. When the tension of the material strip 6 increases, it presses against the second transition roller 432 with a greater force, causing the value detected by the gravity sensor to increase. Conversely, when the tension of the material strip 6 decreases, it presses against the second transition roller 432 with a smaller force, causing the value detected by the gravity sensor to decrease accordingly. The configuration of the three transition rollers 432 and the gravity sensor greatly enhances the sensitivity of the tension adjustment.

[0055] like Figure 1-Figure 2As shown, the unloading mechanism 4 also includes a correction component, which includes a correction detection element (not shown) and an adjustment drive element (not shown). The correction detection element is capable of detecting the axial position of the material strip 6 on the unloading shaft 41 and transmitting a second signal. The output end of the adjustment drive element is connected to the unloading shaft 41, and the adjustment drive element is capable of receiving the second signal and driving the unloading shaft 41 to move along its axial direction. From the perspective of production accuracy, monitoring the position of the material strip 6 provides a reliable basis for subsequent precise adjustments. After receiving the second signal, the adjustment drive element can accurately drive the unloading shaft 41 along its axial direction, thereby correcting the position deviation of the material strip 6 and ensuring that the material strip 6 always remains in the preset operating trajectory, effectively improving the processing accuracy of the material strip 6 and enhancing the reliability of the dressing processing equipment. In terms of production stability, the automatic correction function of the correction component eliminates the need for frequent manual adjustments, avoiding damage to the material strip 6 due to untimely or inaccurate human intervention, ensuring processing continuity, reducing downtime or failure of the dressing processing equipment caused by the material strip 6 deviating 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 discharge mechanism 4 also includes a discharge rack 44. The discharge shaft 41 is rotatably set on the discharge rack 44, and the discharge rack 44 is fixedly connected to the flat plate 45. The flat plate 45 and the frame 1 are slidably connected along the axial direction of the discharge shaft 41. The output end of the adjustment drive is connected to the flat plate 45. The adjustment drive can receive a second signal and drive the discharge rack 44 to move so that the discharge shaft 41 moves along its axial direction, and the position of the discharge shaft 41 is adjusted to keep the material belt 6 in the middle position of the discharge shaft 41.

[0057] Optionally, the adjustment drive member includes a servo motor, a screw and a nut, wherein the servo motor is 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 adjustment drive member is not limited here.

[0058] like Figure 1As shown, the punching device 2 comprises a punch 21, a needle roller 22, and a first lifting assembly 23. The punch 21 is provided with a die hole groove, and the needle roller 22 is positioned below the punch 21. The needle roller 22 is equipped with a protrusion that mates with the die hole groove. The material strip 6 is wound around the needle roller 22. The first lifting assembly 23 drives the punch 21 in a reciprocating motion, allowing the die hole groove to engage or disengage with the protrusion, thereby punching holes in the material strip 6 that match the size and shape of the protrusion on the needle roller 22. This precise alignment ensures precise positioning and uniform size of the punched holes, meeting the stringent requirements for hole position and diameter on the material strip 6 and improving the processing quality of the dressing processing equipment. Furthermore, the needle roller 22 rotates continuously, conveying the material strip 6 continuously. Simultaneously, the punch 21, driven by the first lifting assembly 23, performs a reciprocating motion, achieving continuous punching. Compared to traditional intermittent punching methods, this significantly improves punching efficiency and meets 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 variable amplitude rod and a transducer. The transducer is connected to one end of the variable amplitude rod by threaded connection or welding connection to ensure that the high-frequency vibration generated by the transducer can be effectively transmitted to the variable amplitude rod. The other end of the variable amplitude rod is connected to the mold by threaded connection, welding connection or fasteners. The variable amplitude rod plays the role of amplifying the vibration amplitude output by the transducer. The variable amplitude rod 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 into 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, the dressing processing equipment is equipped with five sets of ultrasonic punches. The mold width of each ultrasonic punch is 200 mm, and it can punch holes in a material strip 6 with a width of 1000 mm at a time. In other embodiments, the number of ultrasonic punches can also be one, two, three, four, six, etc., and this 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 mounted on the frame 1, and the slide is connected to the punch 21 via 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 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 be transmitted, 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, and the punching is completed 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 mounted on the frame 1, and the material strip 6 is wound around the roller 31. The cutter assembly 32 is located above the roller 31 and is capable of cutting the material strip 6 into at least two strips along its width. The roller 31 is rotatably mounted on the frame 1, and the material strip 6 is continuously wound around the roller 31. The roller 31 can assist in supporting and conveying the material strip 6, achieving uninterrupted conveyance. The cutter assembly 32 located above the roller 31 can perform real-time slitting on the moving material strip 6. This continuous slitting method reduces downtime during the production process, greatly improving slitting efficiency and meeting the needs of large-scale production.

[0065] Specifically, if 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. The material strip 6 is arranged between the slitting knife 321 and the roller 31. 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. 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 assembly (not shown), the output end of the second lifting assembly is connected to the slitting knife 321, and the second lifting assembly 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 makes it convenient for the operator to place the material strip 6. There is no need to thread the material in a small space or under the knife, which reduces the difficulty of operation and safety risks. During operation, the second lifting assembly 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 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, thereby improving the overall production efficiency and practicality of the equipment.

[0067] Optionally, the second lifting assembly includes a cylinder, a piston rod in the cylinder can reciprocate in the cylinder, and the piston rod is connected to the slitting knife 321 to achieve the lifting and lowering of the slitting knife 321. 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 positioned downstream of the slitting device 3. The composite roller assembly 47 comprises 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 to enable the upper eccentric rubber roller 472 to move toward or 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., its position 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 compress the material strip 6. This effectively adjusts the thickness of the material strip 6, avoids unevenness around the holes after punching, and ensures punching quality.

[0069] In this embodiment, the composite roller assembly 47 further comprises a synchronous pulley, a transmission belt, a servo motor, and a support. A lower rubber roller 471 and an upper eccentric rubber roller 472 are both rotatably mounted on the support, which is fixedly connected to the frame 1. The synchronous pulley is rotatably mounted on the frame 1. The transmission belt is wound around the outer circumference of the synchronous pulley and the lower rubber roller 471, and can be tensioned by the synchronous pulley and the lower rubber roller 471. The output end of the servo motor is connected to the synchronous pulley, which drives the synchronous pulley to rotate and drive the transmission belt, thereby causing the synchronous pulley and the lower rubber roller 471 to rotate synchronously, driving the material strip 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 strip 6 during transmission between the various process steps. The composite roller assembly 47 further comprises an eccentric handle, the output end of which is connected to the upper mounting seat. The eccentric handle can drive the upper eccentric rubber roller 472 toward or away from the lower rubber roller 471, thereby adjusting the roller gap between the lower rubber roller 471 and the upper eccentric rubber roller 472 to meet the requirements of high-quality dressing processing.

[0070] like Figure 1-Figure 2 As shown, the material receiving mechanism 5 includes a cantilever assembly 51 and a first drive member 52. The cantilever assembly 51 includes a material receiving shaft 511, a cantilever sleeve 512, and a drive source 513. The cantilever sleeve 512 is rotatably connected to the frame 1 about a first axis extending in the vertical direction. The material receiving shaft 511 extends in the horizontal direction and has a first end rotatably connected to the cantilever sleeve 512. The drive source 513 is used to drive the material receiving shaft 511 to rotate to reel in the cut material strip 6. The first drive member 52 is mounted on the frame 1. The cantilever sleeve 512 is in driving connection with the output end of the first drive member 52. The first drive 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 connected to the frame 1 or away from the frame 1. When the cut strip 6 on the take-up shaft 511 needs to be removed, the first drive member 52 is used to drive the cantilever sleeve 512 to rotate around the frame 1, thereby driving the take-up shaft 511 to rotate around the frame 1, and the take-up shaft 511 is separated from the frame 1, so that the cut strip 6 can be removed from the second end of the take-up shaft 511. Compared with the conventional method of completely removing the entire take-up shaft 511 before removing the strip 6 from the take-up shaft 511, this greatly facilitates the operator's unloading of the strip 6, greatly shortens the material removal time, and improves efficiency. Optionally, the first drive member 52 can be a servo motor, a stepper motor, or a pneumatic motor, etc., which are not specifically limited here.

[0071] Furthermore, the drive source 513 can drive the take-up shaft 511 to rotate about a second axis A extending horizontally. During the rewinding process, the speed and torque of the take-up shaft 511 can be precisely adjusted based on the material, thickness, and slitting width of the material strip 6. For thin, easily stretched material strip 6, a relatively low and stable speed can be rewound, ensuring that the material strip 6 is evenly wound around the take-up shaft 511, significantly improving the quality and accuracy of the rewinding. Optionally, the drive source 513 can be a servo motor, a stepper motor, or a pneumatic motor, etc., without specific limitation herein.

[0072] like Figure 2 As shown, the cantilever sleeve 512 rotates about 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 out the materials.

[0073] In this embodiment, the take-up reel 511 can take up one, two, three, or more cut strips 6. The take-up mechanism 5 includes at least two cantilever assemblies 51, which are spaced apart vertically. This facilitates structural compactness and prevents interference between the two cantilever assemblies 51 during take-up of the strips 6. In this embodiment, the take-up mechanism 5 includes at least two cantilever assemblies 51. For dressing processing equipment that cuts the strip 6 into five strips, one take-up reel 511 can take up two strips 6, while the other take-up reel 511 can take up three strips 6.

[0074] Specifically, the 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 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. After 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 fast, which is convenient for the staff to quickly replace the positioning paper core after the receiving is completed, thereby improving efficiency. When the positioning paper core needs to be removed, 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-up 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 sliding shaft. The sliding shaft automatically adjusts the winding tension by virtue of the friction characteristics between itself and the material strip 6, and can maintain stable and appropriate tension at different stages of the winding of the material strip 6, avoiding the material strip 6 from stretching and deforming due to excessive tension, or causing the material strip 6 to become loose due to too little tension. When receiving the material, the sliding shaft can rotate in the opposite direction to adjust the tension of the material strip 6 after winding, facilitate the removal of the material strip 6, and ensure 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. 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 rotational 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 with it to rotate. 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, achieving efficient transmission in a limited space. The reasonable layout facilitates the installation and maintenance of each component, thereby improving the stability of the dressing processing equipment.

[0077] In other embodiments, the material receiving mechanism 5 may further include a first synchronous wheel, a second synchronous wheel, and a transmission belt. The first synchronous wheel is in transmission connection with 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 circumference 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. When the first synchronous wheel rotates, it drives the transmission belt to rotate. When the transmission belt rotates, it drives the second synchronous wheel to rotate. 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. 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 base 12, a limiting chuck 13, and a first drive assembly 14. The mounting base 12 is rotatably engaged with the frame body 11 about a second axis A extending horizontally. The limiting chuck 13 is rotatably engaged with the mounting base 12 about a third axis B extending vertically. A limiting slot 131 is provided on the side of the limiting chuck 13 facing the cantilever assembly 51. The limiting slot 131 is used to limit the second end of the receiving shaft 511. The first drive assembly 14 is disposed on the mounting base 12. The first drive assembly 14 is capable of driving the limiting chuck 13 to rotate from a first position to a second position or from the second position to the first position when the first drive 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 slot 131. In the second position, the second end of the receiving shaft 511 can be disengaged from the limiting slot 131 and away from the frame 1.

[0079] Specifically, when the limiting chuck 13 is in the first position, the second end of the take-up shaft 511 can be firmly inserted into the limiting chuck 13. In the process of the driving source 513 driving the take-up shaft 511 to rotate to reel in the cut material strip 6, the limiting chuck 13 can rotate together with the take-up shaft 511, so that the take-up 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 take-up 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 from the take-up 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 take-up 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 take-up 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. 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 around the second axis A extending in the horizontal direction and cooperates with the frame body 11, so that when the receiving shaft 511 rotates around the second axis A extending in the horizontal direction during the receiving process, the limit 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 mounted on the mounting base 12, with its output end hinged to an eccentric position of the position-limiting chuck 13. The linear drive is capable of outputting horizontal linear motion. This ingenious design converts the horizontal linear motion of the linear drive into rotation of the position-limiting chuck 13 about a third vertical axis B, ensuring that the position-limiting chuck 13 rotates into position in a timely manner, improving the consistency and efficiency of production operations and providing strong support for the stable operation of the dressing processing equipment.

[0083] Specifically, if Figure 3 As shown, the first drive assembly 14 includes a first cylinder 141 and a second cylinder 142. The first cylinder 141 and the second cylinder 142 are both mounted on the mounting base 12 and are 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 guide portion 1312. The limiting portion 1311 extends axially along the limiting chuck 13, and the guide portion 1312 extends radially from the sidewall of the limiting portion 1311. The depth of the guide 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 guide portion 1312. The cantilever sleeve 512 rotates relative to the frame 1. 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 inserted into the limiting portion 1311 along the guide portion 1312. On the one hand, the depth of the guide portion 1312 gradually decreases in the radially outward direction, allowing the receiving shaft 511 to enter the limiting groove 131 more easily, effectively reducing the collision between the receiving shaft 511 and the limiting chuck 13 during rotation, thereby extending the service life of the dressing processing device. On the other hand, the limiting portion 1311 ensures that the receiving shaft 511 does not move during operation, thereby ensuring the stability and accuracy of the receiving operation, thereby improving the receiving quality of the product.

[0085] like Figure 1-Figure 2 As shown, the dressing processing equipment also includes a retrieving device 7, which includes a second drive assembly 72 and a robotic arm 71. The output end of the second drive assembly 72 is connected to the robotic arm 71, and the second drive assembly 72 is capable of driving the robotic arm 71 to move along the take-up shaft 511 to remove the material strip 6 wound on the take-up shaft 511 from the second end of the take-up shaft 511. The second drive assembly 72 of the retrieving device 7 works in conjunction with the robotic arm 71 to automatically remove the material strip 6 wound on the take-up shaft 511 from the second end of the take-up shaft 511, significantly reducing the time cost of manual unloading, allowing the equipment to quickly enter the next round of material collection, and greatly improving the overall production efficiency of the dressing processing equipment. In addition, the second drive assembly 72 of the retrieving device 7 is capable of precisely controlling the movement of the robotic arm 71 along the take-up shaft 511, ensuring smooth and accurate unloading, avoiding damage to the material strip 6, ensuring the quality of the processed material strip 6, 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 robotic arm 71 to drive the robotic 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 drive assembly 72 further includes a rotary drive member (not shown). The output end of the rotary drive member is connected to the robotic arm 71. The rotary drive member can drive the robotic arm 71 to rotate, causing the robotic arm 71 to approach and overlap the take-up shaft 511, thereby removing the web 6 wound on the take-up shaft 511 from the second end of the take-up shaft 511. Alternatively, the rotary drive member can be a servo motor, a stepper motor, or the like, which is not specifically limited herein.

[0088] like Figure 1-Figure 2 As shown, in this embodiment, the robotic arm 71 is a U-shaped robotic arm, and at least part of the material receiving shaft 511 can be extended into the U-shaped opening of the U-shaped robotic arm. The U-shaped robotic arm moves along the material receiving shaft 511, pushing the material strip 6 wound 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 robotic arm 71 can also be a rectangular robotic arm, an arc-shaped robotic 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 strip 6 unloaded from the second end of the material receiving shaft 511, thereby reducing manual handling, improving efficiency, and making the dressing processing equipment operate 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 collection mechanism 5 also includes a scrap collection shaft 55 and a motor (not shown). The scrap collection shaft 55 extends horizontally and is rotatably connected to the frame 1. The output end of the motor is connected to the scrap collection shaft 55, and the motor can drive the scrap collection shaft 55 to rotate about a fourth axis extending in the horizontal direction. The scrap collection shaft 55 is used to collect scrap with uneven thickness on both sides after cutting the winding strip 6. This effectively solves the problem of waste disposal during the production process, avoids the messy production environment caused by the random scattering of waste, and facilitates the subsequent centralized processing of waste, which promotes the standardization and cleanliness 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 scrap collection shafts 55, one located on either side of the frame 1. These shafts 55 are capable of reeling in the uneven thickness of the scrap material on either side of the slitting strip 6. On the one hand, the bilateral arrangement of the scrap collection shafts 55 fully utilizes the space on both sides of the frame 1, avoiding the potential congestion and disorganization of waste material caused by concentrating the waste in one location, thereby providing a more rational and orderly layout for the entire production space. On the other hand, the dual scrap collection shafts 55 can simultaneously reel in the waste material, significantly improving waste collection efficiency.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
