Description

Technical Field

[0001] This invention relates to the field of nursing pants manufacturing technology, specifically to a roll material feeding device for nursing pants manufacturing. Background Technology

[0002] The production of nursing pants involves using raw materials such as non-woven fabric, super absorbent polymer, and elastic materials in an assembly line operation that includes "raw material preparation - core structure forming - composite cutting - finished product processing - quality inspection" to produce disposable sanitary products with leak-proof, absorbent, and fit functions. The core is to achieve efficient water-locking of the absorbent core and a comfortable fit of the pant shape.

[0003] The existing technology still has the following problems:

[0004] 1. Existing technologies mostly use simple shafts to support the core, resulting in an inherent small gap between the core and the shaft. When the roll diameter is large, its own weight can partially fill the gap, resulting in small relative displacement; however, as the diameter gradually decreases, the weight of the roll decreases, the clamping force on the core is insufficient, the fit gap is fully exposed, and radial movement and overall sway are prone to occur when the roll rotates, leading to a decrease in conveying and guiding accuracy, severe wear on the roll edges, and subsequent processing deviations.

[0005] 2. The existing equipment lacks a flexible adaptable structure. When dealing with rolls of material of different widths and inner diameters, it is necessary to frequently adjust the equipment or replace parts, which is cumbersome and time-consuming, and it is difficult to meet the needs of rapid switching of various roll specifications in the production of nursing pants. In addition, there is a lack of a precise dynamic tension adjustment mechanism. When the diameter of the roll decreases, if the torsional torque of the conveyor roller remains unchanged, the tension of the roll will continue to increase, which can easily cause the material to stretch and deform or even break. Manual adjustment or simple mechanical adjustment is difficult to respond to tension changes in real time, resulting in a high material loss rate.

[0006] Therefore, a roll feeding device for the production of nursing pants is proposed. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0035] Please see Figures 1 to 9 An embodiment of the present invention provides a roll material feeding device for the production of nursing pants, including a movable frame 101, a mounting frame 102, a push rod 103 and an external controller. The mounting frame 102 is fixedly connected to the top of the movable frame 101, the push rod 103 is fixedly connected to the side wall of the mounting frame 102, a feeding mechanism 200 is provided on the outer wall of the mounting frame 102, and a protective mechanism 300 is provided at the bottom of the mounting frame 102.

[0036] The feeding mechanism 200 includes a sliding rod 201 symmetrically fixedly connected to the inner wall of the mounting frame 102. A moving table 202 is slidably connected between the outer walls of the two sliding rods 201. The moving table 202 is electrically connected to an external controller. A driving device is installed inside the moving table 202. Under the control of the external controller, the driving device can drive the moving table 202 to slide on the outer wall of the sliding rod 201. A carrying plate 203 is symmetrically fixedly connected to the side of the moving table 202 away from the mounting frame 102. A sliding rod 204 is slidably connected inside the side of the carrying plate 203 away from the moving table 202. A carrying block 205 is fixedly connected to the end of the sliding rod 204 away from the carrying plate 203. Both the carrying plate 203 and the carrying block 205 have an arc-shaped support surface at their top ends. Both the carrying plate 203 and the carrying block 205 are made of rubber.

[0037] The protective mechanism 300 includes a circular plate 301 fixedly connected to the end of the load block 205 away from the load plate 203. The side of the circular plate 301 near the mounting bracket 102 is made of rubber. The interior of the circular plate 301 has three sliding grooves 302 arranged in a circular array. The interior of the sliding grooves 302 has two sliding grooves 303 symmetrically arranged. A shaft cavity rod 304 is fixedly connected through the middle of the circular plate 301. The side of the shaft cavity rod 304 near the load plate 203 is rotatably connected to a guide rod 305. A sealing gasket is provided at the connection between the shaft cavity rod 304 and the guide rod 305, and the sealing gasket can prevent air leakage during the rotation of the guide rod 305 inside the shaft cavity rod 304.

[0038] Furthermore, the feeding mechanism 200 also includes an electric telescopic rod 206 fixedly connected between the load block 205 and the outer wall of the load plate 203. The electric telescopic rod 206 is electrically connected to an external controller. A limiting plate 207 is fixedly connected to the outer wall of the mounting frame 102. A telescopic rod 208 is rotatably connected to the middle of the bottom end of the limiting plate 207. An elastic reset member is provided inside the telescopic rod 208, and the elastic reset member can ensure that the telescopic rod 208 is always in a fully extended state when it is not compressed. Three limiting plates 209 are fixedly connected to the outer wall of the limiting plate 207. Adjustment grooves 210 are symmetrically opened at the bottom end of the limiting plate 207. The size of the adjustment grooves 210 is adapted to the top size of the load plate 203, which can meet the installation requirements of various sizes of roll materials.

[0039] It should be noted that the core function of the electric telescopic rod 206 is to drive the load block 205 to slide along the slide bar 204, thereby driving the protective mechanism 300 to move closer to or away from the limit plate 207, so as to achieve precise docking between the roll material and the downstream conveying structure.

[0040] The size-matched design of the adjustment groove 210 and the carrier plate 203 not only allows for compatibility with rolls of different widths, but also provides guidance and limits when the carrier plate 203 moves up and down, preventing the carrier plate 203 from shifting and causing unstable support of the roll.

[0041] The elastic reset design of the telescopic rod 208 can automatically reset when the slot 307 is disengaged, reserving adaptation space for the next roll material connection. At the same time, its telescopic characteristics can buffer the impact force during roll material connection and prevent the edge of the roll material from being damaged by rigid collision.

[0042] Furthermore, the protective mechanism 300 also includes an abutment rod 306 fixedly connected to the end of the guide rod 305 away from the shaft cavity rod 304. A slot 307 is provided at the end of the abutment rod 306 away from the guide rod 305. The size of the slot 307 matches the size of the telescopic end of the telescopic rod 208. Several through-type sliding grooves 308 are arranged in a circular array on the outer wall of the abutment rod 306. A sliding plate 309 is slidably connected inside the sliding grooves 308. Limiting blocks 3 are symmetrically fixedly connected to the outer wall of the sliding plate 309 near the middle of the abutment rod 306. 10. A rubber airbag 311 is fixedly connected to one end of the slide plate 309 away from the limiting block 310. The slide plate 309 and the rubber airbag 311 are internally connected. A slider 312 is slidably connected inside the slide groove 302. A limiting block 313 is symmetrically fixedly connected to the outer wall of the slider 312. The size of the limiting block 313 is adapted to the size of the slide groove 303. The limiting block 313 slides inside the slide groove 303. A magnetic block 314 is fixedly connected to one end of the slider 312 away from the limiting block 313. The slider 312 is further away from the magnetic block 314. One end of the slide is rotatably connected to a clamping rod 315. A limiting hole is opened and closed inside the second limiting plate 209, and the size of the limiting hole matches the size of the end of the clamping rod 315 away from the circular plate 301. Several limiting rings 316 arranged in a linear array are fixedly connected to the outer wall of the clamping rod 315. Both the limiting rings 316 and the clamping rod 315 are made of rubber. A spring 317 is fixedly connected to the inner wall of the first slide groove 302. A pressure detector is installed inside the slider 312. The spring 317 is fixedly connected to the detection end of the pressure detector installed inside the slider 312. The circular plate 3... 01 A threaded groove plate 318 is fixedly connected to the end away from the contact rod 306. A magnetic block plate 319 is threadedly connected to the outer wall of the threaded groove plate 318. The magnetic poles of the magnetic block 314 and the magnetic block plate 319 are the same on the opposite side. A rubber tube 320 is fixedly connected to the bottom end of the shaft cavity rod 304 near the magnetic block plate 319. The top end of the rubber tube 320 slides through the bottom end of the magnetic block plate 319. The end of the rubber tube 320 away from the shaft cavity rod 304 is fixedly connected to the air pump 321. An air pump 321 is fixedly connected to the outer wall of the moving frame 101 near the load block 205.

[0043] It should be noted that the multiple structures of the protective mechanism 300 form a dual fixing logic of internal support and external clamping: the rubber airbag 311 is inflated by the air pump 321 to achieve adaptive support from inside the roll core, which can be compatible with roll cores of different inner diameters. At the same time, the rubber material can avoid damage to the inner wall of the roll core; the clamping rod 315 clamps the roll from the outside, and together with the rubber limiting ring 316, it can not only limit the lateral movement of the roll, but also reduce friction damage at the clamping point.

[0044] The magnetic block 314 and the magnetic block plate 319 have the same magnetic pole design. In the initial state, the spring 317 is compressed by the repulsive force, so that the clamping rod 315 is in the open state, which is convenient for placing the roll material. After rotating the magnetic block plate 319, the repulsive force disappears, and the elastic force of the spring 317 drives the clamping rod 315 to clamp the roll material. The operation is convenient and the fixation is reliable.

[0045] The pressure detector inside the slider 312 is connected to the spring 317, which can monitor the change in the elastic force of the spring 317 in real time, indirectly reflecting the clamping force of the clamping rod 315, and providing data support for subsequent tension adjustment.

[0046] Working principle: In the initial state, the electric telescopic rod 206 is in a fully extended state, and the spring 317 is in a fully contracted state.

[0047] When working, refer to Figures 1 to 6 As shown, the operator first places the roll material on top of the carrier plate 203, then pushes the roll material towards the side closer to the circular plate 301, causing the roll material to move to the top of the carrier block 205. Simultaneously, the contact rod 306 moves into the roll core until the end of the roll material away from the mounting bracket 102 is in contact with the circular plate 301. At this point, the operator controls the air pump 321 via an external controller to fill the rubber tube 320 with nitrogen. The nitrogen then enters the shaft cavity rod 304 through the rubber tube 320, and through the shaft cavity rod 304 and the guide rod 305 into the contact rod 306. Finally, the nitrogen enters the rubber air bladder 311 through the sliding plate 309. As the nitrogen level inside the rubber air bladder gradually increases, it begins to expand away from the contact rod 306, causing the rubber air bladder 311 to expand further. During the process, the slide plate 309 slides outward inside the slide 308 until the rubber airbag 311 inflates to fully contact the inner wall of the core, thereby enabling the rubber airbag 311 to initially fix various sizes of rolls. Traditionally, when feeding rolls, most of the time the core is placed on the shaft and the roll is rotated by an external drive rod. However, since there is inevitably a small gap between the core and the shaft, when the diameter of the roll is large, the core is compressed by its own weight, and the gap is filled, so the relative displacement between the core and the support shaft is small. But when the diameter is small, the weight of the roll is reduced, the compressive force on the core is insufficient, the gap is fully exposed, and when the roll rotates, the core will have a slight radial movement on the support shaft, which will eventually cause the roll to shake. Therefore, the roll will lose precise guidance during transport.

[0048] The air pump 321 drives the rubber airbag 311 to expand adaptively from inside the core to fill the gap between the core and the contact rod 306. At the same time, the spring 317 drives the rubber clamping rod 315 to clamp from the outside. With the limit ring 316, lateral movement is restricted. Even if the diameter of the roll gradually decreases, radial movement and shaking can be avoided, which significantly improves the conveying and guiding accuracy and reduces wear on the edge of the roll and processing deviation.

[0049] refer to Figures 3 to 9 As shown, after the initial fixing of the roll material is completed, the operator manually rotates the magnetic block plate 319, causing the magnetic block plate 319 to slide on the outer wall of the threaded groove plate 318 away from the circular plate 301. This moves the magnetic block plate 319 to a position that is not on the same vertical plane as the magnetic block 314. Consequently, the slider 312, under the action of the spring 317, slides inside the slide groove 302 towards the threaded groove plate 318. This causes the slider 312 to drive the clamping rod 315 to slide towards the roll material, allowing the clamping rod 315 to clamp the outer wall of the roll material and limit the roll material horizontally through the limiting ring 316.

[0050] Subsequently, the operator controls the moving platform 202 to slide upwards on the outer wall of the slide bar 201 via an external controller. This causes the moving platform 202 to move the carrying plate 203 upwards synchronously. The carrying plate 203, through the slide bar 204 and the carrying block 205, drives the electric telescopic rod 206 upwards synchronously, and through the carrying block 205, drives the circular plate 301 upwards synchronously. When the circular plate 301 moves the abutment rod 306 to the same straight line as the telescopic rod 208, the operator controls the electric telescopic rod 206 to retract via the external controller. This causes the electric telescopic rod 206 to move the carrying block 205 and the circular plate 301 upwards synchronously. 1. Move towards the side closer to the telescopic rod 208, causing the load block 205 to drive the slide rod 204 to slide into the load plate 203, causing the circular plate 301 to drive the abutment rod 306 to move synchronously, causing the abutment rod 306 to drive the slot 307 to move synchronously, causing the telescopic rod 208 to slide into the slot 307 and abut against the slot 307, causing the telescopic end of the telescopic rod 208 to retract until the roll material abuts against the limiting plate 1 207. At this time, the electric telescopic rod 206 stops working, and then the operator connects the feeding end of the roll material to the external conveying roller, so that the conveying roller feeds the roll material.

[0051] Initially, when the coil diameter is large, the total mass and moment of inertia are high, acting as an inertial stabilizer. Even under slight external forces (such as fluctuations in conveyor speed or equipment vibration), it can maintain stable rotation due to its own inertia and is not prone to swaying. However, as the diameter gradually decreases, the total mass decreases significantly, and the moment of inertia decreases sharply, causing the inertial stabilization effect to fail. At this point, the coil's resistance to external disturbances decreases significantly. For example, small fluctuations in the conveyor roller's rotational speed or changes in the friction between the guide roller and the coil can directly cause vibration or swaying of the coil. As the coil diameter decreases, if the torsional torque of the conveyor roller remains constant, the decreasing coil diameter will cause the tension on the coil to continuously increase. On the one hand... Excessive tension can stretch the thin rolls of non-woven fabric and composite film used in the production of nursing pants, damaging the original properties of the materials. This can lead to problems such as size deviation and abnormal elasticity in the subsequently processed nursing pants. In extreme cases, excessive tension can even tear the rolls apart. When the diameter of the roll decreases, the clamping rod 315 will move closer to the contact rod 306 under the elastic action of the spring 317, thereby reducing the elastic force of the spring 317. Since forces are reciprocal, the pressure of the spring 317 on the pressure detector inside the slider 312 will also decrease. This will control the torsional force of the conveyor roller through the pressure detector, thereby reducing the pulling force of the conveyor roller on the roll.

[0052] Driven by the electric telescopic rod 206, with the size-adaptive adjustment groove 210 and the self-adaptive design of the rubber airbag 311, it can be compatible with rolls of different widths and inner diameters without frequent equipment modifications, and can adapt to various roll specifications for the production of nursing pants. In addition, the pressure detector inside the slider 312 monitors the change in the elasticity of the spring 317 in real time, dynamically feedbacks and adjusts the torsional torque of the conveyor roller, avoiding tension loss caused by the reduction of the roll diameter, preventing the material from being stretched, deformed or torn, effectively reducing the material loss rate and improving the product yield.
