The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The embodiment of the present invention provides a rough edge repair device for producing diapers, such as Figure 1-8As shown, it includes a trimming machine 1; the side position of the trimming machine 1 extends upward to form a processing seat 2 for support; an upper clamping mechanism is arranged on the side of the processing seat 2 opposite to the table of the trimming machine 1; the trimming machine 1 is provided with a lower positioning mechanism matched with the upper clamping mechanism; wherein the lower positioning mechanism comprises: a transmission block 3 arranged on the trimming machine 1, a displacement sensor is arranged on the side wall of the transmission block 3, and the transmission block 3 and the trimming machine 1 are in sliding cooperation; a processing table 4 for repairing the raw edges of diapers is arranged on the transmission block 3, and the processing table 4 and the transmission block 3 are provided between For rotational cooperation; a positioning and trimming base plate 5 which is consistent with the outer diameter of the diaper is arranged on the processing table 4; a stretching block 6 is arranged in the middle position of the upper surface of the positioning and trimming base plate 5, and the stretching block 6 and the positioning and trimming base plate 5 are snap-fitted; the stretching block 6 is an arc-shaped convex structure which is high in the middle and low on both sides; a negative pressure cavity is opened in the positioning and trimming base plate 5; a plurality of adsorption holes 7 which are connected with the negative pressure cavity are arranged at the side edge position of the upper surface of the positioning and trimming base plate 5; a vacuum pump 8 is arranged on the outer wall of the positioning and trimming base plate 5, and one end of the vacuum pump 8 is connected with the negative pressure cavity through a flexible tube 9.

[0033] It should be noted that, since the traditional method of repairing the rough edges of diapers has obvious deficiencies in accuracy, flexibility and environmental protection, this solution adopts a stretching block 6 with an arc-shaped convex structure and a negative pressure chamber designed inside the positioning and trimming bottom plate 5, which effectively avoids the wrinkles of the diaper caused by the flexible material, provides a high-precision basis for subsequent processing, and cooperates with the fastening block 18 for precise pressing, further improving the stability of the diaper during the rough edge trimming process, and corrects the curling problem that may be caused by a single rigid fixation. At the same time, the adsorption cover 23 set can efficiently absorb and collect waste and debris generated during the cutting process, prevent impurities from interfering with subsequent processing procedures, improve processing efficiency, and ensure the cleanliness and safety of the working area; in addition, by setting a freely rotatable processing table 4, the rough edges of the diaper at different angles are fully and timely trimmed, the flexibility and comprehensiveness of the trimming are enhanced, and the diaper is ensured to always remain in a fastened state during the trimming process, avoiding dislocation or looseness problems.

[0034] Specifically, in this embodiment, the scheme mainly includes a trimming machine 1; the diaper is placed on the stretching block 6 on the positioning trimming bottom plate 5, and the stretching block 6 adopts an arc-shaped convex structure, which can fully stretch the flat diaper, effectively avoiding wrinkles caused by the flexible material of the diaper, thereby ensuring high precision in the cutting process; a negative pressure chamber is designed inside the positioning trimming bottom plate 5, and a stable negative pressure is generated under the action of a vacuum pump 8. This negative pressure acts accurately on the side of the diaper through the adsorption holes 7 arranged on the side edge of the upper surface of the positioning trimming bottom plate 5, and firmly adsorbs it on the positioning trimming bottom plate 5; in this state, the diaper is not only firmly lifted up by the stretching block 6, but also its side is firmly fixed by the negative pressure, forming a stable and precise working state;

[0035] At the same time, the transmission block 3 is firmly mounted on the trimming machine 1. Through the sliding fit mechanism, the transmission block 3 can be moved smoothly and accurately in the horizontal direction, which greatly improves the coordination with the upper clamping mechanism. In order to ensure the accuracy of the movement of the transmission block 3, its side wall is specially equipped with a high-precision displacement sensor, which can monitor and record the position information of the transmission block 3 in real time, thereby ensuring that each step of movement meets the expected accuracy requirements.

[0036] In addition, the processing table 4 is installed on the transmission block 3. Through the flexible rotation and matching mechanism, the user can easily adjust the angle of the processing table 4 to meet the actual needs of repairing the rough edges at different positions of the diaper.

[0037] In a further preferred embodiment of the present invention, Figure 5 As shown, the upper clamping mechanism includes: an extension support 10 arranged at the upper position of the processing base body 2, and the extension support 10 is vertically distributed with the processing base body 2; a screw slide 11 is arranged at the bottom position of the extension support 10 along its axial direction; the movable end of the screw slide 11 is connected to the first receiving plate 12; a hydraulic cylinder 13 is arranged at the bottom position of the first receiving plate 12; the telescopic end of the hydraulic cylinder 13 is connected to the second receiving plate 14.

[0038] In this embodiment, the extended support 10 ensures the stability and supporting force of the entire structure. The screw slide 11 can drive its moving end to perform smooth and precise horizontal movement through its precise moving mechanism. The moving end of the screw slide 11 is connected to the first connecting plate 12. The first connecting plate 12 serves as a transition component. It not only bears the weight above, but also realizes further vertical movement function through the hydraulic cylinder 13 at its bottom. The telescopic end of the hydraulic cylinder 13 is closely connected to the second connecting plate 14. The height position of the second connecting plate 14 can be accurately adjusted through the telescopic movement of the hydraulic cylinder 13.

[0039] In a further preferred embodiment of the present invention, Figure 5As shown, the upper clamping mechanism also includes: a third receiving plate 15 arranged at the bottom position of the second receiving plate 14, and the third receiving plate 15 and the second receiving plate 14 are rotatably matched; a group of fastening brackets 16 are symmetrically arranged on both sides of the third receiving plate 15, and a proximity sensor is arranged on the fastening bracket 16; the bottom ends of the two fastening brackets 16 away from each other are respectively connected to a group of return springs 17, and a damper is integrated in the return spring 17; a plurality of return springs 17 are respectively connected to a fastening block 18 on one side away from the fastening bracket 16, and the bottom of the fastening block 18 is chamfered.

[0040] In this embodiment, the third receiving plate 15 can rotate relative to the second receiving plate 14 to adapt to various angle processing requirements. When the diaper is placed in the working area, the proximity sensor will monitor the real-time distance between it and the diaper. Once the preset position is reached, the fixing mechanism will be triggered;

[0041] At this time, the third receiving plate 15 will drive the reset spring 17 and the fastening block 18 to move downward smoothly. The fastening block 18 accurately fixes the four side positions of the diaper to ensure that the diaper remains highly stable during the processing. The damper integrated in the reset spring 17, while providing the necessary elastic reset force, effectively reduces the impact and vibration that may be generated when the fastening block 18 moves, thereby ensuring the stability and accuracy of the entire operation process; the bottom of the fastening block 18 adopts a chamfered design, which reduces the friction when in contact with the diaper, reduces the risk of potential damage, and enhances the stability of the contact, making the fastening process smoother and safer.

[0042] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a mounting frame 19 is provided on the side of the upper surface of the trimming machine 1, a robot arm 20 is provided on the side of the mounting frame 19 opposite to the processing table 4, a moving end of the robot arm 20 is connected to a mounting plate 21, a laser trimming head 22 is provided at the bottom of the mounting plate 21, and a photoelectric sensor is provided on the outer side wall of the laser trimming head 22.

[0043] In this embodiment, through the movement of the robotic arm 20, the laser trimming head 22 is accurately positioned to the position where cutting is required, and then the laser trimming head 22 is used to perform the cutting operation. At the same time, the photoelectric sensor monitors the cutting process in real time to ensure the accuracy and safety of the cutting. This process realizes the automated and high-precision cutting of diapers.

[0044] In a further preferred embodiment of the present invention, Figure 7 As shown, an adsorption hood 23 is provided on the side of the processing base 2 opposite to the table top of the trimming machine 1, and a slag collecting box 24 is provided on the side of the processing base 2 away from the trimming machine 1. The slag collecting box 24 is connected to the adsorption hood 23 through a conduit 25, and a filter layer 26 is provided in the slag collecting box 24.

[0045] In this embodiment, the adsorption hood 23 transports the waste and debris generated by cutting to the slag collecting box 24 through the conduit 25. A filter layer 26 is provided inside the slag collecting box 24. The main function of the filter layer 26 is to filter out fine particles in the waste and debris to prevent them from being released back into the environment with the air to cause secondary pollution.

[0046] In a further preferred embodiment of the present invention, Figure 7 As shown, a fan 27 is provided on the side wall of the slag collecting box 24 , and an adsorption end of the fan 27 is connected to the slag collecting box 24 .

[0047] In this embodiment, negative pressure is generated when the fan 27 is in operation, and this negative pressure is transmitted to the adsorption hood 23 through the slag collecting box 24 and the conduit 25, so that a low-pressure area is formed inside the adsorption hood 23. Due to the existence of the pressure difference, impurities such as waste and debris generated during the cutting process on the trimming machine 1 are adsorbed into the adsorption hood 23 and then transported to the slag collecting box 24 through the conduit 25.

[0048] In a further preferred embodiment of the present invention, Figure 5 As shown, a rotating motor 28 is disposed on the side wall of the transmission block 3 , and an output end of the rotating motor 28 is fixedly connected to an end key of the processing table 4 .

[0049] In this embodiment, the rotating motor 28 serves as a power source, and its output end is connected to the processing table 4 through a key connection, which can drive the processing table 4 to rotate. This rotation function allows the diapers on the processing table 4 to adjust their angles during the cutting process, thereby meeting more complex cutting requirements.

[0050] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a guide groove 29 for sliding the transmission block 3 is provided in the middle of the upper surface of the trimming machine 1, and an electric telescopic rod 30 is provided on the side of the processing base 2 opposite to the transmission block 3, and the output end of the electric telescopic rod 30 is connected to the transmission block 3.

[0051] In this embodiment, the electric telescopic rod 30 serves as a power source, and drives the transmission block 3 to slide along the guide groove 29 through telescopic movement, thereby realizing automatic feeding of diapers. This design not only improves the efficiency of diaper feeding, but also ensures the stability and accuracy of the feeding process.

[0052] In a further preferred embodiment of the present invention, Figure 1-8 As shown, a control console 31 is disposed beside the trimming machine 1 , and the control console 31 is electrically connected to the upper clamping mechanism and the lower positioning mechanism.

[0053] In this embodiment, through the console 31, the operator can easily input instructions to control the upper clamping mechanism and the lower positioning mechanism to stably and accurately fix the diaper. At the same time, the console 31 can also receive feedback information from various sensors, thereby achieving precise control and adjustment of the entire cutting process.

[0054] Working principle: The diaper is placed on the stretching block 6 on the positioning and trimming bottom plate 5; the stretching block 6 adopts an arc-shaped convex structure, which can fully stretch the flat diaper, effectively avoiding wrinkles caused by the flexible material of the diaper, and providing high-precision guarantee for the subsequent cutting process; at the same time, the negative pressure cavity designed inside the positioning and trimming bottom plate 5 generates a stable negative pressure under the action of the vacuum pump 8, and this negative pressure accurately acts on the side of the diaper through the adsorption holes 7 on the side edge of the upper surface of the positioning and trimming bottom plate 5, firmly adsorbing it on the positioning and trimming bottom plate 5, ensuring the stability of the diaper during the cutting process;

[0055] Next, the transmission block 3 is driven by the electric telescopic rod 30 to slide along the guide groove 29 to the bottom of the extension support 10, thereby realizing the automatic feeding of the diapers. In order to improve the accuracy of the feeding process, the side wall of the transmission block 3 is specially equipped with a displacement sensor to monitor and record the position information of the transmission block 3 in real time, ensuring that each step of movement meets the expected accuracy requirements.

[0056] The screw slide 11 at the bottom of the extension support 10 drives its moving end to move smoothly and accurately horizontally through its precise moving mechanism; connected to the moving end of the screw slide 11 is the first receiving plate 12, which, as a transition component, not only bears the weight above, but also realizes further vertical movement function through the hydraulic cylinder 13 at the bottom; the telescopic end of the hydraulic cylinder 13 is closely connected to the second receiving plate 14, and the height position of the second receiving plate 14 can be accurately adjusted through the telescopic movement of the hydraulic cylinder 13;

[0057] When the diaper is placed in the working area, the proximity sensor will monitor the real-time distance between it and the diaper; once it reaches the preset position, the fixing mechanism will be triggered; at this time, the third receiving plate 15 will drive the reset spring 17 and the fastening block 18 to move downward smoothly, and the fastening block 18 accurately fixes the four side positions of the diaper, ensuring the high stability of the diaper during the processing; the damper integrated in the reset spring 17, while providing the necessary elastic reset force, effectively reduces the impact and vibration that may be generated when the fastening block 18 moves, ensuring the stability and accuracy of the entire operation process; the bottom of the fastening block 18 adopts a rounded design, which significantly reduces the friction and potential damage risk when in contact with the diaper, making the fastening process smoother and safer;

[0058] Then, the robot arm 20 starts to move and accurately positions the laser trimming head 22 to the position where cutting is required; after receiving the instruction, the laser trimming head 22 immediately performs the cutting operation; at the same time, the photoelectric sensor monitors the cutting process in real time to ensure the accuracy and safety of the cutting; this process realizes the automatic and high-precision cutting of diapers;

[0059] The processing table 4 can be flexibly rotated by the drive of the rotary motor 28; this rotation function allows the diapers on the processing table 4 to be adjusted in angle during the cutting process, thereby meeting more complex cutting requirements;

[0060] During the cutting process, the negative pressure generated by the fan 27 is transmitted to the adsorption hood 23 through the slag box 24 and the conduit 25, so that a low-pressure area is formed inside the adsorption hood 23; due to the existence of the pressure difference, impurities such as waste and debris generated during the cutting process on the trimming machine 1 are adsorbed into the adsorption hood 23, and then transported to the slag box 24 through the conduit 25; the filter layer 26 arranged inside the slag box 24 effectively filters out fine particles in the waste and debris, preventing them from being released back into the environment with the air, thereby ensuring the cleanliness and safety of the environment.
