Description

Technical Field

[0001] This utility model relates to the field of sanitary product production equipment, specifically to a phase-arranged conveying device. Background Technology

[0002] Sanitary napkin products, especially period panties, are designed for easy carrying when going out. They are individually packaged in small sizes and made of biodegradable plastic or PE film. The packaging features easy-tear openings and sealing strips to prevent contamination and make them suitable for carrying in pockets, handbags, and other similar situations.

[0003] In production, the small package size is not fixed inside the film, which makes it easy for the product to shift during transportation. In order to prevent the sealing and cutting process from crushing the product and causing waste, the only option was to lengthen the small package size to make the space inside the film large enough to allow for product movement and ensure production stability. However, this wastes materials, and the larger the package, the higher the cost. Utility Model Content

[0004] Therefore, this utility model provides a phase-arranged conveying device, which solves the problem of small package products being easily displaced during the conveying process.

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

[0006] A phase-aligned conveying device includes a frame with a mounting bracket on the frame and an adsorption box on the mounting bracket. A belt drive assembly is arranged outside the adsorption box. The belt drive assembly includes a driving pulley located below the adsorption box, driven pulleys located at both ends of the adsorption box, and a synchronous belt wound around the outer surfaces of the driving pulley and the two driven pulleys. The surface of the synchronous belt is evenly distributed with a plurality of baffles. When the device conveys, small packages are confined between two adjacent baffles.

[0007] Preferably, the meshing surface between the synchronous belt and the driving pulley and driven pulley is a toothed surface.

[0008] Preferably, the tooth surface of the synchronous belt has an outwardly convex portion and a concave portion between the two convex portions, and each of the stop bars is disposed in the concave portion.

[0009] Preferably, the driven pulley is a double-tooth pulley structure with two different tooth profiles.

[0010] Preferably, the belt drive assembly further includes an adjusting pulley located below the two driven pulleys for increasing the engagement point of the synchronous belt, and each adjusting pulley is connected to an adjusting bracket for adjusting the tension of the synchronous belt.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0012] Addressing the production pain points of individual sanitary napkin / menstrual panty packs—small pack size, lack of product fixation within the wrapping film, easy misalignment during transport leading to high rejection rates due to sealing and cutting damage, and the need to lengthen the pack size to allow for margins—this technical solution uses evenly distributed baffles on the surface of the synchronous belt to form equidistant intervals (the spacing equals the width of the pack). Each pack is strictly limited between two baffles, ensuring a constant spacing between packs during transport (e.g., accurate to ±0.5mm). This completely solves the problems of pack misalignment and misalignment before and after folding during traditional smooth synchronous belt transport, achieving precise positioning and phase alignment.

[0013] The physical limit of the baffle bar keeps the small package absolutely still before sealing and cutting. During sealing and cutting, the blade can be precisely aligned with the edge of the small package (instead of the traditional method which requires a safety margin). The machine's operating speed is increased by more than 30%, while the scrap rate is reduced to below 0.5%, which greatly improves the machine's stability and speed.

[0014] Because there is no need to lengthen the size of the small bag, the material cost of a single small bag is reduced by 15-20%, and the smaller size of the small bag is more compact, making it more suitable for portable scenarios such as pockets and handbags, thus reducing material costs;

[0015] In response to the characteristics of biodegradable plastic / PE films being easily deformed and slipping, the raised structure of the baffle increases the friction with the film material, preventing slippage during conveying, while avoiding the tensile damage to the film material caused by traditional clamping and conveying, thus adapting to the characteristics of biodegradable materials.

[0022] 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.

[0023] Example

[0024] refer to Figures 1 to 3 A phase-aligned conveying device includes a frame 100, on which a mounting bracket 1 is provided. An adsorption box 2 is mounted on the mounting bracket 1. A belt drive assembly is arranged around the adsorption box 2. The belt drive assembly includes a driving pulley 3 located below the adsorption box 2, driven pulleys 4 located at both ends of the adsorption box 2, and a synchronous belt 5 wound around the outer surfaces of the driving pulley 3 and the two driven pulleys 4. A plurality of baffles 51 are evenly distributed on the surface of the synchronous belt 5. When the device conveys, the small package is confined between two adjacent baffles 51. The height of the baffles 51 varies from 5 to 30 mm depending on the product, while the width is not limited, as long as it ensures confinement. Addressing the production pain points of individual sanitary napkin / menstrual panty packages—small package size, lack of product fixation within the wrapping film, easy misalignment during conveying leading to high rejection rates due to sealing and cutting damage, and the traditional need to lengthen the package size to allow for margin—this technical solution uses baffles 51 evenly distributed on the surface of the synchronous belt 5 to form equidistant grooves (the spacing is equal to the width of the package). Each small package is strictly positioned between two baffles 51, ensuring a constant spacing between packages during transport (accurate to ±0.5mm). This completely solves the problems of package misalignment and cross-flow before and after folding when using traditional smooth synchronous belts 5, achieving precise positioning and phase alignment. The physical positioning of the baffles 51 keeps the packages absolutely stationary before sealing and cutting, allowing the blade to precisely align with the edge of the package during sealing and cutting (instead of the traditional method which requires a safety margin). This increases machine speed by more than 30% while reducing the scrap rate to below 0.5%, significantly improving machine stability and speed. Since there is no need to lengthen the package size, the material cost per package is reduced by 15-20%, and the package size is more compact, making it more suitable for pockets, handbags, and other portable applications, further reducing material costs. Addressing the easily deformable and slippery characteristics of biodegradable plastic / PE film, the raised structure of the baffles 51 increases friction with the film material, preventing slippage during transport and avoiding the tensile damage to the film material caused by traditional clamping and transport, thus adapting to the characteristics of biodegradable materials.

[0025] In this embodiment, the meshing surfaces of the synchronous belt 5 with the driving pulley 3 and the driven pulley 4 are toothed surfaces. Compared with traditional smooth belt drives, toothed meshing can achieve slip-free transmission, ensuring that the speeds of the driving pulley 3 and the driven pulley 4 are synchronized, avoiding speed fluctuations caused by slippage, and further improving the phase accuracy of the small package arrangement; the toothed structure can withstand greater tension (traditional smooth belts are prone to creep due to excessive tension), making it suitable for high-speed and heavy-load scenarios, and extending the service life of the synchronous belt 5 (from the traditional 1-2 years to 3-5 years).

[0026] Specific examples Figure 4 As shown, the tooth surface of the synchronous belt 5 has an outwardly convex portion 5a and a concave portion 5b between the two convex portions 5a, and each of the stop bars 51 is provided at the concave portion 5b. The tooth surface of the synchronous belt 5 is designed with an outwardly convex portion 5a and a concave portion 5b structure, and the stop bars 51 are only provided at the concave portion 5b to avoid interference between the stop bars 51 and the edge of the pulley when turning. The stop bars 51 at the concave portion 5b will not generate additional resistance due to excessive thickness when the pulley turns, reducing the bending stress of the belt body and reducing the risk of belt body breakage. The convex portion 5a retains the tooth surface structure to ensure the meshing area with the pulley, while the concave portion 5b and the stop bars 51 do not occupy additional space, making the overall thickness of the synchronous belt 5 controllable and suitable for the compact frame 100 design.

[0027] In terms of the specific installation structure, the belt drive assembly also includes an adjusting pulley 6 located below the two driven pulleys 4 to increase the engagement points of the synchronous belt 5. Each adjusting pulley 6 is connected to an adjusting bracket 61 for adjusting the tension of the synchronous belt 5. The adjusting bracket 61 is composed of a bolt and nut assembly and is fixed on the mounting bracket 1. Similarly, the driven pulleys 4 can also be equipped with this structure to achieve the adjustment installation function. The adjusting bracket 61 can finely adjust the tension of the synchronous belt 5 to adapt to the elasticity differences of different batches of belts and reduce the difficulty of installation and debugging. The adjusting pulley 6 increases the number of engagement points between the synchronous belt 5 and the pulley (from the traditional 2-3 to 4-5), forming a "multi-point support" structure, which completely eliminates the risk of slippage during high-speed operation, and is especially suitable for high-precision, high-speed sanitary napkin small package production lines.

[0028] Based on the above, the following solutions may also be adopted: Figure 5 As shown, the driven pulley 4 is a double-tooth pulley structure with two different tooth profiles. The driven pulley 4 employs a double-tooth structure with two different tooth profiles, forming multiple anti-slip mechanisms through differences in tooth density. The high tooth density area provides initial gripping force, while the low tooth density area absorbs impact through deformation during high-speed operation, creating a "rigid-flexible" anti-slip effect. This is particularly suitable for harsh production environments such as humid and dusty conditions, with the anti-slip performance being superimposed. The double-tooth structure can disperse belt stress, avoiding rapid failure caused by localized wear in single-tooth structures, thus increasing the pulley's service life by more than 50%.

[0029] This device, with its innovative structure centered on "stop bar 51 and synchronous belt 5", combined with multiple technologies such as toothed meshing, double-tooth anti-slip, and adjusting pulley 6, achieves three core objectives for the conveying of sanitary napkin pouches: precise positioning, high-speed stability, and material saving. It significantly improves production efficiency and economic benefits, while also meeting the environmental requirements of biodegradable materials, demonstrating significant technological advancement and market application value.
