Description

Technical Field

[0001] The invention relates to the technical field of random inspection of pants-type diapers, in particular to a stretching device for random inspection of pants-type diapers. Background Art

[0002] Pants diapers are daily necessities commonly used by babies. They are a general term for diapers, diapers, and pull-up pants. Dry diapers can keep babies sleeping all night. Due to their strong water absorption, they are commonly called "diapers". Among them, super absorbent resin is an excellent material for making baby diapers. It is made of starch and acrylate as the main raw materials. Its outstanding feature is its amazing water absorption and water storage capacity. Simply comparing traditional diapers with diapers, in terms of breathability, of course traditional diapers are better, and much better, because they only have cloth and no water-isolating substances. However, it is very unfair to judge the pros and cons of the two by such comparison results, because when using traditional diapers, people usually use a layer of water-isolating substance on the outer layer of the diaper, which is absolutely Airtight plastic paper, so we should compare the "complete version" traditional diapers with this layer that has no air permeability at all with diapers. Diapers are made of non-woven fabrics and lined with materials that only allow air to enter and exit but not water molecules. Therefore, although the breathability cannot be compared with pure cloth, it is much better than the "complete version" traditional diapers. With the continuous improvement of production technology, diapers have been improved from the initial single function of leak-proof and urine absorption to leak-proof, breathable, urine-absorbing and antibacterial, and have added multiple functions such as stretchable elastic waistline and three-dimensional leak-proof partitions. Pants-type diapers often need to be randomly inspected and stretched during the production process to test their water absorption effect under normal use.

[0003] For example, the patent document with the announcement number CN 113933163 B discloses a diaper quality detection device and a detection method thereof, comprising a workbench, two guide rails laid on the upper end of the workbench, the two guide rails are inclined, and a slider sliding on each of the guide rails is guided, and the two sliders are always symmetrically distributed and move simultaneously. The present invention puts the diaper on two inclined hooks, and drives the guide sliders at the same time, so that the tension generated by the movement of the guide sliders can apply force to the inner end surface of the diaper, so that the diaper is stretched, and the maximum tension that the diaper can reach is detected by judging the displacement distance of the guide slider. At the same time, the angle of the fixed arm can be adjusted, and the fixed arm can be regularly reciprocated through the wavy undulating track, and the undulating law of the two fixed arms can be controlled at the same time, so as to imitate the stretching limit that the diaper in motion can reach.

[0004] However, when the structure is actually stretching and testing pants-type diapers for acceptance, due to the limitation of the sampling structure, it is often only possible to perform simple overall stretching and water absorption detection operations on the pants-type diapers, and it is impossible to perform stretching and water absorption detection operations adapted to the actual wearing scenarios for the pants-type diapers, resulting in the final detected water absorption effect being unable to more truly restore the use quality effect of the pants-type diapers. The sampling results have serious limitations and cannot better reflect the use effect of the pants-type diapers. At the same time, the equipment is unable to perform rapid positioning sampling and loading and unloading operations on the pants-type diapers, and the test water for the water absorption test cannot quantitatively complete the water absorption operation. The efficiency of the sampling is relatively low and cannot meet the daily use needs. Therefore, it is urgent to design a pants-type diaper acceptance sampling and stretching device to solve the above problems. Summary of the invention

[0016] Preferably, a movable storage box is movably connected to the back side of the supporting base, and a material discharge frame is arranged at the top end of the supporting base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The acceptance sampling and stretching device for pants-type diapers can enable the equipment to perform acceptance sampling and stretching operations adapted to the actual use scenarios of pants-type diapers by means of the U-shaped frame, imitation buttocks module, supporting base frame, storage slot, extension tube, telescopic rod, liquid control valve, detection probe, waist ring seat, leg ring seat, waist ring airbag, leg ring airbag, lifting frame, side seat, side frame, positioning frame, rotating disk, third drive motor, positioning inclined slot, air delivery hole slot, suction unit, suction net slot, torsion shaft, unloading inclined plate, air delivery net slot, opening plate, water outlet rack, monitoring rack, movable storage box and unloading frame. In actual use, the staff first puts the pants-type diapers to be inspected into the The diaper is placed on the rotating disk on the surface of the positioning frame, and then the detection probe on the top wall of the U-shaped frame is started to detect the opening position of the pants-type diaper, and the third driving motor at the bottom of the rotating disk is started to drive the rotating disk to perform the rotation adjustment operation of the pants-type diaper, and the opening position of the pants-type diaper is aligned with the imitation hip module inside the U-shaped frame. At this time, the telescopic rods on both sides of the center of the storage slot are started, and the extension tube and the liquid control valve are cooperated to transport the imitation hip module as a whole to the opening position of the pants. When the imitation hip module contacts the pants-type diaper, the opening plate of the leg ring seat first guides the pants-type diaper to be initially supported, and then the suction units at the upper and lower ends of the storage slot are started to suck air from the suction net. Air is sucked in through the grooves and blown into the interior of the imitation hip module through the air delivery hole grooves, and then the air flow can enter the interior of the pant-type diaper along the air delivery net grooves of the leg ring seats, and the entire pant-type diaper is blown and inflated, so that the entire imitation hip module can be quickly and smoothly extended into the interior of the pant-type diaper. At this time, air can be inflated by inflating the waist ring airbags and leg ring airbags on the sides of the waist ring seat and the two groups of leg ring seats, and the pants openings and the two leg openings of the pant-type diaper can be stretched, stretched and sealed appropriately, so that the pant-type diaper can simulate the shape of daily wear on the outer surface of the imitation hip module, and then the water outlet strips on the outer surface of the imitation hip module are used to control the liquid. The monitoring bars on both sides of the water outlet bar rack perform water leakage detection operations, thereby realizing a comprehensive water injection inspection operation into the pants type diapers, so that the pants type diapers can be inspected for water absorption effect in a stretched state closest to normal use, thereby improving the final quality of the pants type diapers. At the same time, when the waist ring airbags and leg ring airbags of the waist ring seat and the leg ring seat are exhausted, the pants type diapers can fall downward under the gravity of water absorption, and then fall on the unloading inclined plate of the U-shaped frame. The unloading inclined plate is opened by the torsion shaft to allow the pants type diapers after water absorption to enter the movable storage box from the unloading frame of the supporting base frame for sealed centralized collection, which reflects the practicality of the equipment design.

[0019] The pants-type diaper acceptance random inspection stretching device further improves the overall use effect of the equipment through the U-shaped frame, lifting frame, liquid dispensing box, liquid dispensing tube, side seat, side frame, positioning frame, rotating disk, motor frame, first drive motor, feed inclined plate, rotating seat, docking roller, docking pad, limit arc groove, limit slider, mounting plate, mounting groove, separation frame, liquid uniformity valve, liquid replenishment valve, second air cushion motor, lifting screw rod, screw rod sliding sleeve, infusion tube seat and pressurizing unit. In daily use, the staff can adapt the equipment as a whole to the position of the pants-type diaper discharge conveyor belt through the mounting plate and the mounting groove at one end of the side frame. Daily use only requires intermittent starting of the first drive motor on the side of the motor frame. Under the limit of the limit arc groove and the limit slider, the feed inclined plate and the rotating seat as a whole can be adaptively docked with the conveyor belt discharge port position. The docking pad of the rotating seat can be positioned and docked with the positioning inclined groove at one end of the positioning frame. The docking roller at the end is adjusted to roll in coordination with the conveyor belt, so that the pant-type diaper sampling samples on the conveyor belt quickly enter the rotating disk on the surface of the positioning frame along the feed ramp, and then the feed ramp is rotated and reset to accurately complete the sampling operation of the pant-type diapers. At the same time, liquid can be injected from the refilling valve at the top of the dispensing tube on a daily basis, and then the test liquid is evenly flowed to the inside of the dispensing box through the separation frame and the uniform liquid valve on the front of the dispensing tube. In the subsequent water absorption test, the second air cushion motor at the top of the lifting frame can be started to drive the lifting screw at one end to rotate, and then the lifting and lowering adjustment of the infusion tube seat is driven by the screw sleeve to guide the test liquid inside each dispensing box to the pressurizing unit one by one, and finally to the inside of the imitation buttocks module through the pressurizing unit, so that the inside of each group of sampled pant-type diapers can be quantitatively absorbed by the test liquid, which greatly improves the overall inspection efficiency of the equipment and reflects the comprehensiveness of the equipment design.
