Description

Technical Field

[0001] This utility model relates to the field of down comforter core technology, and in particular to a device for stabilizing and bonding double-layer fabrics of down comforters. Background Technology

[0002] Double-layered down comforter fabric typically refers to a composite structure consisting of an upper and lower layer of fabric. This structure requires stable bonding to ensure the strength of the connection between the two layers. This double-layer design aims to improve the comforter's warmth and three-dimensional support, while using high-density fabric to prevent down leakage. Due to the high loft and low thermal conductivity of down, stable bonding of the double-layered fabric is crucial to maintaining structural integrity. In existing technologies, the bonding of double-layer fabrics mainly relies on manual sewing or adhesive application. Manual sewing requires operation line by line, which is inefficient and prone to dense needle holes due to operational errors, posing a risk of down leakage. Although adhesive application can partially fill gaps, it is difficult to avoid fabric wrinkles. These wrinkles not only affect the appearance but also weaken the bonding strength, reduce stability, and ultimately affect the warmth, durability, and anti-mildew and antibacterial properties of the down comforter. Therefore, this utility model proposes a stable bonding device for the double-layer fabric of a down comforter core to solve the problems existing in the prior art. Summary of the Invention

[0003] To address the aforementioned issues, this utility model proposes a stable bonding device for double-layer fabric of down comforter cores. This device automates the entire process of feeding, straightening, gluing, compacting, and rolling up the down comforter core fabric, saving manpower and increasing efficiency.

[0004] To achieve the purpose of this utility model, the utility model is achieved through the following technical solution: a stable bonding device for double-layer fabric of down comforter core, including a base plate and a fabric roller. The fabric roller is provided with two sets for releasing the fabric, and the two sets of fabric rollers are rotatably arranged above and below the left side of the front side of the base plate. A solid adhesive film roller is rotatably arranged at the middle position of the left side of the base plate, and the solid adhesive film roller is used to release solid adhesive film. A tensioning assembly is provided on the substrate at the right end of the fabric roller, and at least two sets of tensioning assemblies are provided. The tensioning assembly is used to tension the fabric. A heated compaction roller is rotatably provided on the substrate at the right end of the tensioning assembly, and the heated compaction roller is used to compact the fabric and solid adhesive film to form the finished fabric. A storage roller for winding the finished fabric is rotatably provided on the right end of the front side of the substrate.

[0005] A further improvement is that the tensioning assembly includes an adjustment groove and a guide block. The adjustment groove is located on the base plate and has two sets, upper and lower. The guide block is slidably arranged inside the adjustment groove, and a tensioning roller is rotatably arranged on the front side of the guide block.

[0006] A further improvement is that: the upper and lower sets of adjustment grooves are equipped with bidirectional screw rods that rotate inside, and the upper and lower ends of the bidirectional screw rods pass through the two sets of guide blocks at the upper and lower ends respectively and are threadedly adapted; the top of the substrate is provided with a handle, and the handle is connected to the bidirectional screw rods.

[0007] A further improvement is that: the heated compaction roller is provided with at least four sets, and each pair of heated compaction rollers is adapted to each other. The heated compaction roller includes a roller body, an electric heating wire and a rubber sheet. The electric heating wire is located on the outside of the roller body, and the rubber sheet is located on the outside of the electric heating wire.

[0008] A further improvement is that a conductive slip ring is rotatably connected to the front side of the roller, and the conductive slip ring is connected to a wire and an electric heating wire.

[0009] A further improvement is that a side plate is provided at the middle position of the left end of the substrate, and the solid adhesive film roller is rotatably mounted on the side plate.

[0010] A further improvement is that a damping bearing is provided at the rotational connection between the fabric roller and the substrate, and the fabric roller rotates in a damped manner through the damping bearing.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model uses two sets of fabric rollers to release the fabric to be bonded. The two layers of fabric are tensioned and straightened by two sets of tensioning components and enter the inner side of the heated compaction roller. Simultaneously, the solid adhesive film roller releases solid adhesive film between the two layers of fabric and enters the inner side of the heated compaction roller. The solid adhesive film is heated and melted into adhesive by the heated compaction roller and then compacted between the two layers of fabric to bond them together to obtain the finished fabric. The finished fabric is then wound up by the winding roller.
