Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing equipment, specifically to a branch transfer mechanism used in the production of adult diapers. Background Technology

[0002] In the category of adult diapers, the ear tabs used for securing the diaper are usually large wings or strip structures due to the size of the product. Some designs even mimic the shape of an "ear," hence the nickname "big ears." In the production of this product category, as shown in the authorization announcement number CN 217097963 U, a peripheral cutting transfer device is proposed, comprising a frame, a cutting roller and an adsorption transfer roller disposed on the frame, the two ends of the cutting roller being fitted with first bearing seats, the cutting roller being rotatably disposed on the frame via the first bearing seats, the two ends of the adsorption transfer roller being fitted with second bearing seats, the adsorption transfer roller being rotatably disposed on the frame via the second bearing seats, the adsorption transfer roller having an annular groove inside, and a plurality of adsorption holes being uniformly disposed on the outer circumferential surface of the adsorption transfer roller, the adsorption holes extending into the annular groove, the frame being provided with an annular suction box, the annular suction box extending into the annular groove, the annular suction box having a plurality of suction holes, and the annular suction box being connected to a suction pipe.

[0003] This structure cannot be applied to branch conveying. Utility Model Content

[0004] Therefore, this utility model provides a branching transfer mechanism that solves the problem that existing transfer mechanisms cannot achieve branching transport.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A diversion and transfer mechanism includes a frame with a conveyor line for transporting ear loop material. The angle at which the ear loop material is input is defined as an initial angle. A set of cutting rollers for cutting the ear loop material into ear loop one and ear loop two is mounted on the frame. An adsorption conveyor wheel is mounted on the frame following the cutting rollers. Transfer roller sets for receiving ear loop one and ear loop two are sequentially mounted on the frames at 180° and 270° after rotation from the initial angle. Transfer rollers for receiving ear loop one and ear loop two are respectively mounted on both sides of the adsorption conveyor wheel. The two separate air distribution plates, namely air distribution plate one and air distribution plate two, are used for air separation. The adsorption conveying wheel includes: a central shaft with a gas channel in the radial center; a roller body rotatably mounted on the central shaft with a plurality of suction holes on its surface; a suction pipe with one end connected to a negative pressure device and the other end connected to the gas channel on the central shaft; and an air blowing pipe with one end connected to a gas source and the other end connected to air distribution plate one and air distribution plate two.

[0007] Preferably, the side end of the roller body is provided with air distribution holes one and two for adsorption of ear strap one and ear strap two, respectively, and the air distribution holes one and two are arranged alternately along the circumference of the roller body.

[0008] Preferably, the radial distance between the first air distribution hole and the axis of the roller body is greater than the radial distance between the second air distribution hole.

[0009] Preferably, the transfer roller assembly includes a transfer wheel and a matching pressure roller.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0011] This technical solution adopts a compact layout of "single adsorption conveyor wheel + dual-angle transfer roller group (180° / 270°)". After being slit, ear straps one and two are adsorbed by the adsorption conveyor wheel, and then rotate with the wheel to a preset angle. They are then precisely detached by air blowing through the air distribution plate, completing the dual-path conveying. This design significantly simplifies the equipment structure, reduces the number of parts in the complex layout of traditional multi-roller systems, lowers equipment costs, and improves the convenience of adjustment and maintenance. It adapts to the rapid changeover requirements of flexible production lines and is a core embodiment of structural compactness and functional integration. Attached Figure Description

Detailed Implementation

[0016] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Example

[0018] refer to Figure 1 and Figure 2A diversion and transfer mechanism includes a frame with a conveyor line for conveying ear loop material 100. The input angle of the ear loop material 100 is defined as the initial angle. A cutting roller group 1 for cutting the ear loop material 100 into ear loop one 100a and ear loop two 100b is arranged on the frame. An adsorption conveying wheel 2 is arranged on the frame following the cutting roller group 1. Transfer roller groups 3 for receiving ear loop one 100a and ear loop two 100b are sequentially arranged on the frames at 180° and 270° after rotation from the initial angle. In this embodiment, the transfer roller group 3 includes a transfer wheel 31 and a matching pressure roller 32. The transfer roller group 3 adopts a combination structure of the transfer wheel 31 and the pressure roller 32. Through appropriate pressure control by the pressure roller 32, it ensures that ear loop one 100a and ear loop two 100b are tightly attached to the transfer wheel 31 during the transfer process, avoiding deviation during conveying. To prevent wrinkles or detachment, ensuring the continuity of subsequent processes and the stability of product quality, this method is particularly suitable for high-speed automated production lines with stringent requirements for consistent material delivery. The adsorption conveyor wheel 2 is equipped with air distribution plates 4 and 5 on both sides for blowing air off ear loops 100a and 100b, respectively. The adsorption conveyor wheel 2 includes: a central shaft 21 with a gas channel 21a in its radial center; a roller 22 rotatably mounted on the central shaft 21 with a plurality of suction holes on its surface; a suction pipe 23, one end of which is connected to a negative pressure device, and the other end of which is connected to the gas channel 21a of the central shaft 21; and a blowing pipe 24, one end of which is connected to an air source, and the other end of which is connected to the air distribution plates 4 and 5. This technical solution achieves an integrated design for the separate conveying of ear loop material 100 after slitting through an innovative layout of a single adsorption conveyor wheel 2 and dual transfer roller groups 3 at 180° and 270°. During normal conveying, the ear loop material 100 is slid into ear loop one 100a and ear loop two 100b by the cutter roller group 1, and is immediately adsorbed by the suction holes on the surface of the adsorption conveyor wheel 2. As the adsorption conveyor wheel 2 rotates to the 180° and 270° positions, through precise air distribution plate one 4 and air distribution plate two 5, ear loop one 100a and ear loop two 100b detach from the adsorption wheel and are transferred to the corresponding transfer roller groups 3, completing the efficient separation. This design significantly simplifies the equipment structure—only a single adsorption conveyor wheel 2 is needed to achieve the entire process of dual-path slitting-transfer-conveyance, reducing the number of parts in the complex layout of traditional multi-roller systems, lowering equipment costs, and significantly improving the convenience of adjustment and maintenance, adapting to the rapid changeover requirements of flexible production lines.

[0019] Structurally, the side end of the roller body 22 is provided with air distribution holes 221 and 222 for adsorption of ear loops 100a and 100b, respectively. The air distribution holes 221 and 222 are staggered along the circumference of the roller body 22. This staggered arrangement is as follows: Figure 3 As shown, air distribution holes 1 221 and 222 form two arc-shaped arrays of holes, arranged sequentially around the circumference of the roller 22. The staggered design of air distribution holes 1 221 and 222 around the roller 22 creates a dynamic matching system with the rotation sequence of the adsorption conveyor wheel 2 and the ventilation action of the air distribution plate. When the adsorption conveyor wheel 2 rotates to the corresponding angle, air distribution holes 1 221 and 222 align sequentially with the ventilation holes of the air distribution plate, achieving precise air release control of ear loops 100a and 100b, avoiding misalignment or material damage caused by air release timing deviations, and ensuring the accuracy of branched conveying and product consistency. For example... Figure 3 It can be seen that there are three overlapping holes at the connection between air distribution hole 1 221 and air distribution hole 222 to ensure stable delivery at the connection.

[0020] The radial distance between the first air distribution hole 221 and the axis of the roller body 22 is greater than the radial distance between the second air distribution hole 222. That is, the first air distribution hole 221 and the second air distribution hole 222 are located on different diameter rings. This difference in radial dimensions creates a staggered distribution of the two air distribution holes in the radial direction of the roller body 22, avoiding stress concentration problems caused by dense openings in a single ring. This layout improves the structural strength of the roller body 22, reduces the risk of fatigue cracks during high-speed operation, extends the service life of the adsorption conveyor wheel 2, reduces the frequency of downtime and maintenance due to damage to the roller body 22, and improves production efficiency and stability.

[0021] This technical solution achieves efficient integration of the entire process of ear loop material 100-fold cutting and branching conveying through innovative design. With the addition of the air distribution plate and adsorption conveying wheel 2, it realizes the functional requirements of precise control, strength optimization and stable conveying, forming a highly efficient full-process solution of "cutting-adsorption-branching-conveying". It is suitable for the stringent requirements of high-speed automated production lines for material conveying consistency and equipment maintenance convenience.
