Description

Scratch-proof conveying flat belt for SMT production line

Technical Field

The utility model relates to the technical field of conveying flat belts, in particular to an anti-scratch conveying flat belt for an SMT production line.

Background

The prior conveying flat belt mainly uses a polyamide sheet base transmission flat belt or a light conveying flat belt, the polyamide sheet base flat belt which is mainly used for transmission is mostly selected on an SMT production line at present and is used for conveying, the polyamide sheet base flat belt mainly uses transmission power, a transmission mechanism is required to be matched with a belt wheel with a larger diameter (a large turning radius) or at least the diameter of the belt wheel is required to meet the thickness selection of the flat belt, but the SMT production line belongs to high-precision high-speed compact equipment, the diameters of the belt wheels which are designed and selected at home and abroad are smaller, and the minimum diameter is 8mm, so the universal polyamide sheet base flat belt is easy to bend, fatigue burst and large in conveying jumping in the actual application to influence the production efficiency and can only temporarily substitute but is not durable; the light-weight PVC or PU conveying flat belt mainly adopts light-load conveying, but is not good when applied to an SMT production line because the belt is easy to elongate and skid due to high-speed bearing; no matter the polyamide sheet base flat belt or the light conveying flat belt, the wear resistance of the flat belt can be reduced on the surface friction material as long as the antistatic performance is improved.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the scratch-resistant conveying flat belt for the SMT production line, which can effectively solve the problems in the background art.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a prevent mark conveying flat belt for SMT produces line, includes conveyor belt body, conveyor belt body is equipped with main part pulling force layer, main part pulling force layer surface is equipped with the surface material layer, the surface material layer is including laminating upper coat, the top surface layer on main part pulling force layer surface in proper order, main part pulling force layer bottom is equipped with the bottom surface bed of material, the bottom surface bed of material is including laminating under lower coating, the bottom surface layer in main part pulling force layer bottom in proper order, main part pulling force layer is a nylon sheet basic unit, upper coat and lower coating are a polyurethane layer, the upper surface layer is a plain velvet polyester non-woven fabrics layer with lower surface layer.

Further, gluing and attaching are carried out between all layers inside the conveyor belt body.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the utility model provides an anti-scratch flat conveyor belt for an SMT production line, comprising a conveyor belt body, wherein the conveyor belt body is provided with a main body tension layer 1, the surface of the main body tension layer 1 is provided with a surface material layer 2, the surface material layer 2 comprises an upper coating 201 and an upper coating 202 which are sequentially attached to the surface of the main body tension layer 1, the bottom of the main body tension layer 1 is provided with a bottom material layer 3, the bottom material layer 3 comprises a lower coating 301 and a lower coating 302 which are sequentially attached to the bottom of the main body tension layer 1, the main body tension layer 1 is a nylon sheet base layer, the upper coating 201 and the lower coating 301 are both polyurethane layers, the upper coating 202 and the lower coating 302 are both flat-pile polyester non-woven fabrics, after the main body tension layer 1 composed of the nylon sheet base layer is subjected to flexibility treatment, the size is stable and is not easy to elongate, the flatness is good, and the static upper coating 201 and the lower coating 301 composed of the polyurethane layers can remove the upper coating 202 and the lower coating 302 on both sides The upper layer 202 and the lower layer 302 which are composed of the velveteen polyester non-woven fabric layer have high wear resistance and antistatic effect, and form larger adhesive force with the conveyed objects, so that the wear resistance is extremely high.

The gluing laminating between each aspect of the inside conveyer belt body, the compactness between each aspect can be strengthened to the gluing laminating, and the rubber coating generally can select to scribble soft glue and ensure the compliance of conveying flat band.
