Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and in particular to a sheet sorting device for producing diapers. Background Art

[0002] The sheet sorting device used in diaper production is an important equipment to ensure production efficiency and product quality on the diaper production line. It is mainly composed of a feeding mechanism, a sheet sorting mechanism and a discharging mechanism. The feeding mechanism is responsible for transporting the randomly stacked diaper sheets to the sheet sorting link in an orderly manner. It usually adopts a conveyor belt with an automatic material dividing device to evenly feed the diaper sheets one by one. The sheet sorting mechanism is the core part, and it often uses mechanical arms, vacuum suction cups or brushes and other components to work together. The mechanical arm accurately grasps and adjusts the position of the diaper sheets, the vacuum suction cups adsorb and fix them, and the brushes comb and smooth out wrinkles. Through these actions, it ensures that each diaper is in a flat and correctly placed state. The discharging mechanism neatly delivers the sorted diaper sheets to the next production process, such as the packaging link. This device can not only greatly improve the sheet sorting efficiency, but also reduce the errors caused by manual operation, ensuring that each diaper enters the subsequent process in a standard posture, laying the foundation for the mass production of high-quality diapers.

[0003] However, the existing sheet sorting devices used in diaper production have many shortcomings during production. First, in terms of efficiency, the sheet sorting speed cannot meet the growing demand for large-scale production. Its mechanical structure design is not optimized, and the coordinated operation between the various components is not smooth, which leads to the diaper sheets being easily stuck during the transmission and sorting process. Frequent pauses greatly affect the overall production efficiency. Second, the accuracy is insufficient, making it difficult to ensure that each diaper can be accurately sorted into the appropriate position. The sensor has limited sensitivity and poor adaptability to diapers of different sizes and materials, which is prone to sheet sorting deviations, causing some diapers to be positionally shifted in subsequent processing links, affecting product quality. Third, the equipment is unstable. When running continuously for a long time, it is prone to malfunctions due to problems such as component wear and heat. The maintenance cost is high and the downtime is long, which seriously affects the continuous operation of the production line. In addition, the convenience of operation and maintenance is not ideal. The complicated operation process increases labor costs and the probability of error, and the difficulty of maintenance further reduces the effective use time of the equipment, which has a certain adverse impact on people's use process. In order to address the shortcomings of the existing technology, we propose a sheet sorting device for diaper production. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the symmetrical structural design of the sprocket chain ensures that the two sets of sprockets and chains run synchronously and stably, so that the support rod moves cyclically along the chain trajectory, laying a stable foundation for the sheet sorting work. The sheet sorting frame uses a rotating sliding sleeve to achieve multi-angle adaptive adjustment, which can better adapt to diapers in different postures and positions, ensuring smooth sheet sorting. The first electric telescopic rod pushes the limit frame, driving the sheet sorting clamp to slide, and cooperates with the gear plate to achieve layered positioning and accurate clamping and sorting of diapers, ensuring that diapers are neatly arranged in a predetermined manner. At the same time, the ultraviolet lamp is turned on synchronously to sterilize the surface of the diapers, improve the sanitary quality, and provide reliable protection for subsequent production and use.

[0017] 2. In the present invention, the first rack is pushed by the second electric telescopic rod, so that the first cylindrical gear drives the electric clamp to accurately clamp the sorted diapers. At the same time, the second rack is linked by the connecting rod to drive the second cylindrical gear to drive the blanking punch head and the electric clamp to move synchronously. The protective head can accurately locate the packaging bag and avoid damage to the packaging bag during punching, thereby ensuring the smooth and efficient diaper packaging process. In addition, the deflection groove and the return spring have significant coordination effects. The deflection groove provides trajectory restriction for the movement of the first deflection frame to ensure stable and accurate movement; the return spring provides reverse pulling force when the second electric telescopic rod retracts, so that each component returns to its initial position, ensuring coordinated and orderly two-way movement, and laying a solid foundation for continuous and efficient blanking and packaging work.

[0018] 3. In the present invention, the second servo motor of the cleaning structure drives the rotating disc, connecting rod and bevel gear to swing the two sets of mirror-symmetrical second deflection frames, drive the roller to move in the limiting slide, and then adjust the position and pressure of the first cleaning roller. This design can enable the first cleaning roller to maintain appropriate contact pressure with the sheet sorting block, effectively remove paper scraps, fibers and other debris remaining on the surface of the sheet sorting block, and ensure the cleanliness of the sheet sorting block. At the same time, the staggered setting of the two sets of related components makes the cleaning process more comprehensive and efficient, and can cover different parts of the sheet sorting block to achieve dead-angle cleaning. In addition, after the first cleaning roller cleans the sheet sorting block, it contacts the second cleaning roller, and the second cleaning roller cleans the first cleaning roller to further reduce the residual debris. All of these provide good conditions for subsequent sheet sorting work and improve the overall quality and efficiency of diaper production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] Example 1, as Figure 1-Figure 7As shown, the first servo motor 21 is powered on and starts to operate, so the first sprocket 22 will rotate synchronously with the rotor of the first servo motor 21. Since the side wall of the first sprocket 22 is driven by a chain 24, and the end of the chain 24 away from the first sprocket 22 is driven by a second sprocket 26, the second sprocket 26 is driven to rotate synchronously. Since the first sprocket 22, the chain 24, the positioning baffle 25, the second sprocket 26, and the support rod 27 are set as a group, and there are two groups in total, both of which are mirror-symmetrically arranged with the middle part of the second linkage column 221 as the center, both ends of the first linkage column 23 are fixedly installed with the axis of the first sprocket 22, and the second linkage column 2 Both ends of 21 are fixedly installed at the axis of the second sprocket 26. This symmetrical structure allows the two sets of sprockets and chains to run synchronously and stably. As the chain 24 is driven, several support rods 27 equidistantly fixed on the outer side of the chain 24 will move cyclically along the trajectory of the chain 24. When the support rods 27 move, the film sorting rack 210 will move with the support rods 27, and due to the presence of the rotating sleeve 29, the film sorting rack 210 can achieve multi-angle adaptive adjustment, which can make the film sorting rack 210 better adapt to diapers in different postures and positions, ensuring the smooth progress of the film sorting work. In the process of the film sorting rack 210 moving, when the first When an electric telescopic rod 212 is started, its telescopic end will push the limit frame 213 to move. When the limit frame 213 moves, it will drive the sliding column 218 to slide in the first limit slide groove 214 and the second limit slide groove 215, thereby causing the sheet sorting clamp 217 to slide accordingly. At the same time, the sheet sorting clamp 217 is slidably installed with a first fixed rod 216 on the middle part of one side close to the sliding column 218. The two ends of the first fixed rod 216 are fixedly installed with the shift plates 220 on both sides of the sheet sorting frame 210. The function of the shift plate 220 is to limit and position the sliding of the sheet sorting clamp 217, so that the sheet sorting clamp 217 can accurately position the diapers in layers. When the clamping block 217 slides to the appropriate position under the push of the first electric telescopic rod 212, the diapers can be accurately clamped and arranged in layers to ensure that each diaper can be arranged neatly in a predetermined manner. While the multi-layer sheet sorting structure 2 is sorting the sheets, several ultraviolet lamps 103 arranged inside the opposite sides of the two protective shells 102 will be turned on synchronously. The ultraviolet rays emitted by the ultraviolet lamps 103 have the effect of sterilization and disinfection. During the sheet sorting process, the ultraviolet lamps 103 can sterilize the surface of the diapers, effectively killing bacteria and viruses on the surface of the diapers, improving the sanitary quality of the diapers, and providing protection for subsequent production and use.

[0041] Example 2, as Figures 8-11As shown, the second electric telescopic rod 32 is fixedly mounted on the upper part of the side of the unloading base 31 close to the first support frame 1. When receiving the working instruction, its telescopic end begins to extend, pushing the first fixed block 322 fixedly connected thereto to move forward. Since the first fixed block 322 is fixedly mounted with the first rack 33 on the outer wall of the side away from the first support frame 1, the first rack 33 will move with the first fixed block 322. When the first rack 33 moves, its meshing relationship with the first cylindrical gear 35 causes the first cylindrical gear 35 to start rotating. A third linkage column 36 is fixedly mounted on the axis of one side of the first cylindrical gear 35. Therefore, the third linkage column 36 will rotate synchronously with the first cylindrical gear 35. The outer wall of the third linkage column 36 is equidistantly fixed with several The first positioning block 37 and the side of the first positioning block 37 away from the third linkage column 36 are fixedly installed with an electric clamp 38. As the third linkage column 36 rotates, the electric clamp 38 will rotate to a suitable position. Since the electric clamp 38 corresponds to the middle position of the two sheet sorting blocks 217 and the number is the same, the electric clamp 38 can accurately clamp the diapers that have been sorted in the sheet sorting blocks 217. When the first rack 33 moves, the first connecting rod 310 rotatably installed on the side close to the deflection groove 39 will also move accordingly. The first deflection frame 312 is rotatably installed on the end of the first connecting rod 310 away from the first rack 33. The first deflection frame 312 deflects in the positioning seat 311. Since the first deflection frame 312 is away from the first The second rack 315 is rotatably installed on one side of the connecting rod 310, and the second rack 315 is rotatably installed on the side of the second connecting rod 314 away from the deflection slot 39, so the movement of the first rack 33 is transmitted to the second rack 315 through the first connecting rod 310 and the second connecting rod 314, so that the second rack 315 starts to move, and the running directions of the first rack 33 and the second rack 315 are opposite, and the second rack 315 slides in the fourth limiting slot 316, and the side away from the blanking base 31 is meshed with the second cylindrical gear 317. When the second rack 315 moves, it will drive the second cylindrical gear 317 to rotate in the opposite direction. A fourth linkage column 318 is fixedly installed at the axis of one side of the second cylindrical gear 317, and the outer wall of the fourth linkage column 318 is fixedly installed at equal distances. A plurality of second positioning blocks 319 are installed. A blanking punch head 320 is fixedly installed at one end of the second positioning block 319 away from the fourth linkage column 318. With the reverse rotation of the second cylindrical gear 317, the blanking punch head 320 on the fourth linkage column 318 will move synchronously with the electric clamp 38. A protective head 321 is fixedly installed at the telescopic end of the blanking punch head 320. Since the protective head 321 corresponds to the middle position of the two sheet sorting clamps 217 and the number is the same, the protective head 321 can complete the precise stamping and positioning of the packaging bag while the electric clamp 38 clamps the diaper. The design of the protective head 321 can avoid damage to the packaging bag during the blanking and stamping process, ensure the integrity of the packaging bag, and thus ensure that the diapers can be packaged smoothly.During the entire movement process, the deflection slot 39 and the return spring 313 play a crucial coordinating role. The first deflection frame 312 deflects within the deflection slot 39. The deflection slot 39 provides a trajectory limit for the movement of the first deflection frame 312, ensuring its stability and accuracy. At the same time, a return spring 313 is detachably mounted on the upper portion of the first deflection frame 312 away from the fourth limiting slot 316. The end of the return spring 313 away from the first deflection frame 312 is detachably mounted on the upper side of the positioning seat 311. When the second electric telescopic rod 32 retracts, the return spring 313 provides a reverse pulling force, allowing the first deflection frame 312, the second rack 315 and other components to return to their initial positions, ensuring the coordination and orderly progress of the entire bidirectional movement and preparing for the next unloading and packaging operation.

[0042] Example 3, as Figure 12-16As shown, when the second servo motor 44 is powered on and started, its rotor begins to rotate. Since a rotating disc 45 is fixedly installed on the rotor, the rotating disc 45 will rotate synchronously with the rotor. As the rotating disc 45 rotates, the positioning protrusion 46 will make a circular motion around the center of the rotating disc 45. Therefore, the circular motion of the positioning protrusion 46 is transmitted to the fourth connecting rod 48 through the third connecting rod 47, causing the fourth connecting rod 48 to swing, and the second rotating rod 49 will move with the swing of the fourth connecting rod 48. When the second rotating rod 49 drives the first bevel gear 410 to move, the first bevel gear 410 The meshing relationship with the second bevel gear 411 and the third bevel gear 412 causes the second bevel gear 411 and the third bevel gear 412 to start rotating. As the second bevel gear 411 and the third bevel gear 412 rotate, the two sets of mirror-symmetrical rotating columns 413 drive the second deflection frame 414 fixed thereto to swing. During the swinging of the second deflection frame 414, the roller 417 slides in the fifth limiting slot 416, which causes the sliding block 415 to move along the fifth limiting slot 416, and the second cleaning roller 421 contacts the first cleaning roller 420. The two sets of first cleaning rollers 420 are in contact with the sheet sorting block 217. When the roller 417 moves in the fifth limiting slot 416, the position and pressure of the first cleaning roller 420 are adjusted by the positioning block 418 and the sliding block 419. Through this adjustment, it is ensured that the first cleaning roller 420 and the sheet sorting block 217 maintain a suitable contact pressure. When the sheet sorting block 217 passes through the first cleaning roller 420, the first cleaning roller 420 cleans the surface of the sheet sorting block 217, effectively removing the paper scraps, fibers and other debris remaining on the surface of the sheet sorting block 217. The two sets of second deflection frames 414 and the sliding blocks 415, roller 417, positioning block 418, sliding block 419, and first cleaning roller 420 are staggered with each other. This staggered arrangement makes the cleaning process more comprehensive and efficient, and can cover different parts of the sheet sorting clamp 217, ensuring that there are no dead angles in the cleaning, ensuring the cleanliness of the sheet sorting clamp 217, providing good conditions for subsequent sheet sorting work, and improving the overall quality and efficiency of diaper production. After the first cleaning roller 420 cleans the sheet sorting clamp 217, it contacts the second cleaning roller 421, and the second cleaning roller 421 cleans the two groups of first cleaning rollers 420 to reduce residual debris.
