Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an adjustable uniform air structure and a composite fabric hot-melt device. Background Technology

[0002] Thermal fusion bonding technology, a key process in the processing of nonwoven fabrics, typically refers to applying heat to thermoplastic nonwoven fabrics or their composite layers, causing the surface or intermediate structure to melt and soften, followed by pressure bonding to achieve structural connection and functional integration. This technology is widely used in medical protective materials, absorbent products, and filter composite materials. Its fusion effect directly affects the physical strength, functional uniformity, and overall consistency of the product. In existing technologies, after the composite fabric material to be fused enters the thermal fusion equipment, the hot air blowing onto its surface usually needs to pass through a uniform air distribution device to ensure the uniformity of the thermal fusion.

[0003] However, in actual use, most of the ventilation holes on the air distribution device are fixed structures, which cannot be flexibly adjusted according to the composite fabric with different widths, materials or heat-melting requirements, resulting in poor applicability. Utility Model Content

[0004] The purpose of this application is to provide an adjustable air distribution structure to solve the problem of poor applicability of air distribution components in the prior art; in addition, the purpose of this application is to provide a composite fabric hot-melting device including the cooling mechanism for the composite fabric after hot-melting.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides an adjustable air distribution structure, which includes a frame, a connecting assembly, and several sets of air distribution components, wherein:

[0007] The connection assembly includes a connector and a carrier. The carrier is suspended on the frame via the connector and is located below the air supply end of the air supply component.

[0008] Several sets of air distribution components are arranged on the support and above the composite fabric to be heat-melted. Each set of air distribution components includes several air distribution elements spaced apart along the first horizontal direction. The air distribution elements extend along the second horizontal direction so that a first air distribution channel extending along the second horizontal direction is formed between two adjacent air distribution elements. The air supply end of the air supply component is directed toward the air distribution components to supply heated air, which is then delivered to the composite fabric through multiple first air distribution channels to perform heat-melting composite on the composite fabric.

[0009] An adjustment component is provided between two adjacent air distribution components. The adjustment component is configured to adjust the distance between the two adjacent air distribution components in the first horizontal direction, thereby adjusting the ventilation volume of the first air distribution channel.

[0010] Optionally, the adjustment assembly is positioned above the air distribution assembly. The adjustment assembly includes a plurality of adjustment rods spaced apart along a second horizontal direction. Each adjustment rod has a plurality of sets of fixing members spaced apart along a first horizontal direction. Each set of fixing members corresponds to one air distribution component. Each set of fixing members includes a connecting plate and a locking member. The first end of the connecting plate is fixedly connected to the corresponding air distribution component. The second end of the connecting plate is adjustablely mounted on the adjustment rod along the first horizontal direction. The locking member is configured to loosen or fix the second end of the connecting plate relative to the adjustment rod.

[0011] Optionally, the top of the connecting plate has a through hole, through which the adjusting rod passes;

[0012] The adjusting rod is a threaded rod, and the locking components include a first nut and a second nut. The first nut and the second nut are threaded onto the adjusting rod and located on both sides of the connecting plate in the first horizontal direction. The second end of the connecting plate is tightly fixed to the adjusting rod by the cooperation of the first nut and the second nut.

[0013] Optionally, a guide plate is also vertically arranged below some of the air distribution components. The guide plate extends along the second horizontal direction to form multiple second air distribution channels in the first horizontal direction. The width of the second air distribution channel in the first horizontal direction is greater than the width of the first air distribution channel in the first horizontal direction.

[0014] Optionally, the width of the plurality of second uniform air passages in the first horizontal direction decreases sequentially from both ends to the middle in the first horizontal direction.

[0015] Optionally, the air distribution element is a horizontally arranged rectangular tube.

[0016] Optionally, the connecting parts are configured as several vertically arranged rods, the bearing parts are configured as rectangular frames, one end of the rods is connected to the upper end of the frame, and the other end of the rods is hinged to the rectangular frame;

[0017] A boss is provided on the inner side of the bottom of the rectangular frame, and the two ends of the air distribution component are set on the boss along the second horizontal direction.

[0018] A composite fabric hot-melt equipment, comprising any of the above-mentioned composite fabric hot-melt equipment.

[0019] Compared with the prior art, the adjustable uniform airflow structure proposed in this application has the following advantages:

[0020] 1) By setting up several air-uniforming components and adjusting their spacing individually through the adjustment assembly, the size of the first air-uniforming channel can be changed, thereby achieving flexible adjustment of the hot air flow direction and air volume distribution to meet the hot-melting requirements of composite fabrics of different specifications, thus improving the applicability of the equipment.

[0021] 2) Through the cooperation of the threaded rod, the first nut, the second nut and the connecting plate, an adjustment component that is precise in adjustment, simple in structure and stable is provided.

[0022] 3) By widening the design of the second uniform air passage, the hot air generates a buffer diffusion effect as it flows out of the first uniform air passage and enters a wider area, effectively reducing the local wind speed gradient, reducing the formation of turbulence and improving the stability of the airflow.

[0023] 4) By successively reducing the width of multiple second uniform air channels, the flow rate of hot air blown from the air supply end to the uniform air component is balanced in several second uniform air channels after passing through the first uniform air channel, thereby ensuring the uniformity of heat melting of the composite fabric.

Each set of air distribution components 30 includes components along a first horizontal direction ( Figure 1 Several air-distributing elements 31 are spaced apart in the direction of X (in the middle), and the air-distributing elements 31 are arranged along the second horizontal direction (in the middle X direction). Figure 2 The air supply component extends in the direction of Y to form a first air supply channel 310 extending in the second horizontal direction between two adjacent air supply components 31. The air supply end of the air supply component is directed toward the air supply assembly 30 to supply heated hot air, which is then delivered to the composite fabric through multiple first air supply channels 310 to perform hot melt bonding on the composite fabric.

[0033] An adjustment component 40 is provided between two adjacent air distribution components 31. The adjustment component 40 is configured to adjust the distance between the two adjacent air distribution components 31 in the first horizontal direction, thereby adjusting the ventilation volume of the first air distribution channel 310.
