Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric bonding, in particular to a flat pressing multifunctional hot melt bonding machine. BACKGROUND

[0002] Single performance fabric often cannot meet the actual use requirements, and is beneficial to the decoration fabric in the automobile. For example, the performance of the automobile fabric mainly includes wear resistance, air permeability, waterproofness, tear resistance, aging resistance, environmental protection, etc. Therefore, bonding of multiple fabrics into a composite fabric is a common practice in the industry to increase the functions of the fabric.

[0003] Most of the bonding of multiple fabrics uses glue bonding or hot melt adhesive film welding. The existing fabric bonding machine can only bond with glue or melt the hot melt adhesive film, and the function is relatively single. At the same time, after the fabric is unwound, the traditional fabric bonding machine needs to be stopped to replace and splice the new roll of fabric, which greatly reduces the production efficiency. SUMMARY

[0004] To solve the above problems, the present application discloses a flat pressing multifunctional hot melt bonding machine, which comprises a glue spreading machine, a flat pressing mechanism and a hot melt bonding mechanism.

[0005] The inside of the glue spreading machine is provided with a glue spreading mechanism or a glue film unwinding mechanism to spray glue or place glue film between the two fabrics. The glue film referred to here is a hot melt adhesive film, which is a film product with or without release paper, and can be conveniently operated continuously or intermittently. It can be widely used for bonding various fabrics, paper, high polymer materials and metals. According to the requirements of the fabric production process, the two fabrics can be bonded with glue or welded with glue film. Therefore, the selection of the production process of the two can realize the multifunction of the bonding machine.

[0006] The flat pressing mechanism comprises two conveying belts arranged in an upper and lower position and bonded with each other, and the fabric after glue spreading passes between the two conveying belts. The flat pressing of the fabric after glue spreading or glue film insertion can improve the flatness of the fabric, and at the same time remove the gas between the two fabrics, especially the distribution of the applied glue is more uniform, which is beneficial to improve the quality of the fabric.

[0007] The hot melt bonding mechanism comprises two pressing rollers, and the pressing rollers are provided with electric heating elements, and the fabric after flat pressing passes between the two pressing rollers. The pressing rollers further press the two fabrics, and if the glue film is used, the electric heating elements generate heat, and the glue film melts to weld the two fabrics.

[0008] Preferably, a first temporary storage conveyor rack and a second temporary storage conveyor rack are provided on one side of the gluing machine. The first temporary storage conveyor rack and the second temporary storage conveyor rack are arranged in an upper and lower position. The first temporary storage conveyor rack and the second temporary storage conveyor rack are both provided with a conveyor belt, and the fabrics are stacked in a wave-like manner on the conveyor belt. The upper and lower arrangement greatly reduces the floor space occupied by the equipment and can fully utilize the upper space of the factory area. The purpose of providing the first temporary storage conveyor rack and the second temporary storage conveyor rack is to allow the fabrics to be stacked thereon. After the current roll of fabric is unwound and a new roll of fabric is added, the length of fabric reserved on the conveyor belt satisfies the splicing of the new roll of fabric while not affecting the production of subsequent processes, thus achieving a roll-changing operation without stopping the machine, which is conducive to improving production efficiency.

[0009] Preferably, a first unwinding mechanism is provided at the lower part of one end of the first temporary storage conveyor rack, and a second unwinding mechanism is provided at one end of the second temporary storage conveyor rack. The first unwinding mechanism and the second unwinding mechanism are both used to release the fabric and are common production machinery, so they will not be described in detail here.

[0010] Preferably, a storage rack is provided on one side of the hot melt laminating mechanism. The storage rack comprises a rectangular parallelepiped frame composed of a plurality of rods, with relatively movable crossbeams disposed at the upper and lower portions of the frame, and a plurality of rotating rollers disposed on the crossbeams. The storage rack is used to temporarily store the fabric after lamination. If a welding process is used, it also serves to dissipate heat to a certain extent. At the same time, the movement of the upper and lower crossbeams together releases the temporarily stored fabric. If the upper and lower crossbeams are in contact with each other, the fabric is stored.

[0011] Preferably, a winding mechanism is provided on one side of the material storage rack. The material storage rack is used to provide a time window for the winding mechanism to operate when rewinding.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. It is equipped with glue spraying mechanism and film unwinding mechanism, which are combined with hot melt laminating mechanism. The laminating machine is multifunctional and can be selected according to the process requirements.

[0014] 2. A flattening mechanism is provided. The fabric coated with glue or sandwiched with glue film passes through two conveyor belts, which can improve the flatness of the fabric and minimize the problem of wrinkles on the fabric. If the fabric is coated with glue, the glue can be distributed more evenly between the two fabrics.

[0015] 3. A first temporary storage and conveying rack and a second temporary storage and conveying rack are provided, and are arranged in an upper and lower position, which reduces the floor area and makes full use of the space above the factory building.

[0016] 4. A first temporary storage conveyor rack and a second temporary storage conveyor rack are provided. When a new roll of fabric is replaced, the remaining fabric on the conveyor belt can meet the needs of splicing the new roll of fabric without stopping the machine.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS
