A folding mechanism for Velcro fasteners on diapers

Abstract

This utility model discloses a folding mechanism for diaper Velcro fasteners, including a base and two bending mechanisms. A conveyor belt structure is arranged along the length of the upper surface of the base. The two bending mechanisms are symmetrically arranged on both sides of the front of the conveyor belt structure. This utility model relates to the field of diaper manufacturing technology. This folding mechanism for diaper Velcro fasteners, by setting up a conveyor belt structure and two bending mechanisms, allows the worker to simply place the finished diaper on the conveyor belt structure during actual use. The diaper will then automatically move backward under the drive of the conveyor belt structure. During this movement, the two bending mechanisms cause the Velcro fasteners on both sides of the diaper to flip inward. Finally, the limiting pressure strips on both sides continuously press and fix the flipped Velcro structure, thus achieving an automatic folding effect. Only the feeding part requires manual operation, reducing labor intensity and improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of diaper manufacturing technology, specifically to a folding mechanism for diaper Velcro fasteners. Background Technology

[0002] Modern disposable diapers generally consist of three main parts: the outer cover, the absorbent core, and the backing fabric. The outer cover fits tightly to the baby's body, promoting rapid urine penetration and effectively preventing backflow, keeping the diaper surface dry. The absorbent core, or core, is the heart of the diaper, primarily responsible for capturing and quickly absorbing urine, dispersing it, or diffusing it throughout the core layer via capillary action, ultimately absorbing and storing urine. During production, Velcro is attached to the waistband of the diaper, and this Velcro needs to be folded up later for packaging and shipping.

[0003] Chinese Patent Publication No. CN 214018144 U discloses a folding mechanism for Velcro fasteners on diapers. During use, it can be fixed without pressing with both hands, and the loading and unloading speed is fast, freeing up the hands to perform other operations. It adopts mechanization to replace manual folding, realizes automation, is extremely convenient to use, and greatly improves folding efficiency.

[0004] While the aforementioned patents can improve the efficiency of diaper production to some extent, their main operation method is still manual loading and unloading, and manual control of some structures is still required for folding operations. The degree of automation is low, and the efficiency improvement is not significant enough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a folding mechanism for diaper Velcro fasteners, which solves the problem that the main operation method of the aforementioned patents is still manual loading and unloading, and also requires manual control of some structures for folding operations, resulting in low automation and insufficient efficiency improvement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding mechanism for a diaper Velcro fastener, comprising a base and two bending mechanisms; a conveyor belt structure is provided along the length of the upper surface of the base, and the two bending mechanisms are symmetrically arranged on both sides of the front of the conveyor belt structure; the two bending mechanisms have identical structures, one of which includes a vertically fixed frame connected to the upper surface of the base and located on the outer side of the front of the conveyor belt structure, a rotating shaft with its rear end inclined upward and extending towards the conveyor belt structure is rotatably connected to the rear surface of the upper part of the frame, a conical block with an outer diameter increasing from front to back is fixedly connected to the outer surface of the rotating shaft along its length, and a servo motor is fixedly connected to the front surface of the upper part of the frame, the output shaft of the servo motor rotatably passing through the frame and fixedly connected to the front end of the rotating shaft.

[0007] Furthermore, the conveyor belt structure includes two side plates fixedly connected to the upper surface of the base along its length direction, and belt rollers are laterally rotatably connected to the front and rear ends of the two side plates, with a conveyor belt disposed between the two belt rollers.

[0008] Furthermore, the two conical blocks are hollow inside and their lower surfaces are parallel to the upper surface of the conveyor belt.

[0009] Furthermore, an inner groove is provided in the middle of the outer surface of the conveyor belt.

[0010] Furthermore, a power motor is laterally fixedly connected to the front part of the outer surface of one of the side plates, and the output shaft of the power motor rotatably passes through the side plate and is fixedly connected to one end of one of the belt rollers.

[0011] Furthermore, fixed seats with top ends extending above the conveyor belt are fixedly connected to the rear ends of both sides of the upper surface of the base and the rear sides of the two bending mechanisms, and a limiting pressure strip extending to the upper part of the conveyor belt is fixedly connected between the two fixed seats on the same side.

[0012] Furthermore, a plurality of uprights are vertically fixedly connected to the outer edge of the upper surface of the base, and a top plate adapted to the length of the base is horizontally fixedly connected to the top of the plurality of uprights. A main pressure strip adapted to the length of the conveyor belt is fixedly connected to the middle of the lower surface of the top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The folding mechanism of the diaper Velcro fastener, by setting a conveyor belt structure and two bending mechanisms, allows the worker to place the finished diaper on the conveyor belt structure during actual use. Then, driven by the conveyor belt structure, the diaper will automatically move to the rear of the device. During the movement, the two bending mechanisms drive the Velcro fasteners on both sides of the diaper to flip inward. Finally, the limiting pressure strips on both sides continuously press the flipped Velcro fastener structure to fix it, thereby achieving the effect of automatic folding. Only the feeding part of the entire equipment requires manual operation, thereby reducing the labor intensity of manual labor and improving work efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a folding mechanism for a diaper Velcro fastener, including a base 1 and two bending mechanisms 7; a conveyor belt structure is arranged along its length in the middle of the upper surface of the base 1, and the two bending mechanisms 7 are symmetrically arranged on both sides of the front part of the conveyor belt structure; the two bending mechanisms 7 have the same structure, one of the bending mechanisms 7 includes a stand 71 vertically fixedly connected to the upper surface of the base 1 and located on the outer side of the front part of the conveyor belt structure, a rotating shaft 72 with its rear end inclined upward and extending in the direction of the conveyor belt structure is rotatably connected to the rear side surface of the upper part of the stand 71, the outer surface of the rotating shaft 72 is fixedly connected to a conical block 73 with an outer diameter that expands from front to back along its length, and a servo motor 74 is fixedly connected to the front side surface of the upper part of the stand 71, the output shaft of the servo motor 74 rotatably passes through the stand 71 and is fixedly connected to the front end of the rotating shaft 72.

[0018] When in use, the device moves the diaper via a conveyor belt. After the worker places the diaper on the conveyor belt, it automatically moves backward. At the same time, the rotating shafts 72 in the two bending mechanisms 7 rotate under the drive of the two servo motors 74, causing the two conical blocks 73 to rotate as well. The two conical blocks 73 rotate in opposite directions: the one on the right rotates clockwise, and the one on the left rotates counterclockwise. Through the rotation of both, the Velcro structures extending from both sides of the diaper bend inward. As the diaper continues to move backward, more of the Velcro bends.

[0019] The conveyor belt structure includes two side plates 2 fixedly connected to the upper surface of the base 1 along its length direction. The front and rear ends of the two side plates 2 are rotatably connected to belt rollers 3, and a conveyor belt 4 is arranged between the two belt rollers 3.

[0020] A power motor 6 is horizontally fixedly connected to the front part of the outer surface of a side plate 2. The output shaft of the power motor 6 rotatably passes through the side plate 2 and is fixedly connected to one end of a belt roller 3.

[0021] The power motor 6 drives a belt roller 3 to rotate, which in turn drives the conveyor belt 4 to move, and the conveyor belt 4 can then drive the diaper to move.

[0022] The two conical blocks 73 are hollow inside and their lower surfaces are parallel to the upper surface of the conveyor belt 4.

[0023] The hollow conical block 73 reduces its own weight and prevents the rotating shaft 72 from bending due to excessive pressure. Its lower surface is parallel to the conveyor belt 4, which ensures that the magic buckle remains horizontal after it bends, making it convenient for subsequent limiting and pressing.

[0024] An inner groove 5 is provided in the middle of the outer surface of the conveyor belt 4.

[0025] The recessed groove 5 corresponds to the protruding part in the middle of the diaper, ensuring that the contact area between the conveyor belt 4 and the diaper is large enough, thus providing sufficient friction to drive the diaper to move and preventing the diaper from shifting or tilting during movement.

[0026] The two rear ends of the upper surface of the base 1 and the rear sides of the two bending mechanisms 7 are fixedly connected to the fixed seats 8 with their tops extending to the top of the conveyor belt 4. The two fixed seats 8 on the same side are fixedly connected to the limiting pressure strips 9 extending to the top of the conveyor belt 4.

[0027] After being bent by the two bending mechanisms 7, the Velcro continues to move backward by the conveyor belt 4. It will move to the bottom of the limiting pressure strip 9. The limiting pressure strip 9 will continuously press and fix the current state of the Velcro, making it shape. Finally, the finished diaper will be sent out from the rear of the device and can be collected in a box.

[0028] Multiple uprights 10 are vertically fixedly connected to the outer edge of the upper surface of the base 1. A top plate 11 with a length matching the base 1 is horizontally fixedly connected to the top of the multiple uprights 10. A main pressure strip 12 with a length matching the conveyor belt 4 is fixedly connected to the middle of the lower surface of the top plate 11.

[0029] The main pressure strip 12 can position the center of the diaper, ensuring that the diaper will not shift during movement.

[0030] When in use, the device moves the diapers via a conveyor belt. After the worker places the diaper on the conveyor belt, it automatically moves backward. Simultaneously, the rotating shafts 72 in the two bending mechanisms 7 rotate under the drive of the two servo motors 74, causing the two conical blocks 73 to rotate in opposite directions: the right one rotates clockwise, and the left one rotates counterclockwise. This rotation causes the Velcro structures extending from both sides of the diaper to bend inward. As the diaper continues to move backward, more of the Velcro bends. After being bent by the two bending mechanisms 7, the Velcro continues to move backward by the conveyor belt 4 until it reaches below the limiting pressure strip 9. The limiting pressure strip 9 continuously presses down, fixing the current state of the Velcro and shaping it. Finally, the finished diaper is sent out from the rear of the device and can be collected in a box.
