Folder-gluers is key equipment in carton and cardboard processing and plays a central role in packaging process. Through an automated or semi-automated process, they convert flat cardboard boxes into structured cardboard or cardboard boxes. In modern packaging industry, the use of folding machine, while ensuring the standardization of products, greatly improved the efficiency of packaging production, to promote the packaging industry scale and standardization played an important role.
The purpose of this paper is to introduce the working principle, type, application industries and advantages of the folding machine, to analyze the basic features and practical value of the folding machine in a comprehensive way, and to help readers deepen their understanding of the folding machine as an important packaging equipment.
How does a folder machine work?
(I) Cardboard Conveying
The feed mechanism is the starting point of cardboard conveying. Pre-treated Cardboard sheets, such as printing, die-cutting and folding, is fed into the machine in an orderly fashion through conveyor belts or feed rollers. In this process, uniform spacing and stable positioning of the plate are crucial to the preparation of the next processing step. Positioning and calibration are essential to ensure precise implementation of the follow-up process. The machine adopts side guards, positioning wheel and other components to position the plate horizontally and vertically, which ensures the accurate positioning of the plate during conveyance, and lays a solid foundation for subsequent operations such as bonding and folding.
(II) Gluing
Glue quantity control is a key step in the gluing process. The folder gluer uses cots, nozzles and other adhesive devices, according to cardboard materials (such as ordinary cardboard, laminate) and adhesive requirements, accurate control of the amount of adhesive. Common glues are hydrocolloids and hot melts. Excessive glue can cause overflow, affecting the product's appearance, insufficient glue can affect bond strength, making cartons or cartons easy to decolletage. Glue application also comes with strict requirements. The device applies glue to specific areas of cardboard, such as creases and overlaps, to ensure the glue is only applied to essential areas, to prevent contamination of non-bonded areas and to maintain the product aesthetically pleasing.
(III) Folding and Folding
Folding is the process by which the basic outline of a carton or carton is formed after bonding. The device uses a crease guide rail and folding mechanism to fold the cardboard according to a pre-set crease to form the desired shape. Pressure bonding ensures a strong bond. After folding, pressing wheel, compression tape and other components of the folding of the adhesive position pressure, speed up the the curing speed of glue, ensure strong adhesion, prevent degumming.
(IV) Product Output
The finished product is further flattened by a forming mechanism to ensure a normal box or carton shape. The finished product is transported to the collection area by conveyor belt, and the entire box gluing process completed.
What are the types of folder machine? How are they classified?
(I) Classification) By degree of automation
Manual folder gluers require manual assistance to complete multiple processes, including the transport, bonding and folding of cardboard. Its structure is relatively simple and equipment costs are low. Suitable for processing of small batch and special box, but the production efficiency is relatively low.
Semi-automatic folder machine automate the gluing and laminating processes, but the placement and folding of cardboard requires manual work. They provide a balance of flexibility and efficiency to make them suitable for small-and medium-sized production.
Fully automatic folder gluers automates the whole process from feed to finished product output. Equipped with intelligent control system, can adapt to various cardboard specifications. Its production efficiency is high, suitable for large-scale standardized production, effectively reduces labor cost and improves production stability.
(II) Classification by bonding method.
Water-based glue folder machine uses a water-based adhesive, such as starch glue or white latex, to apply through rubber roller. This type of folder gluer is suitable for binding paper materials, low cost and more environmentally friendly. Hot-melt glue folder gluers to use hot melt adhesive as adhesive material, before coating the adhesive will be melted through a heating device. It is suitable for laminated cardboard, thick cardboard, etc.. Binding fixture combines binding and binding functions and is mainly used in processing of heavy duty cardboard boxes such as home appliance packaging to improve the packaging's load-bearing capacity.
(III) By applicable product category
Folding carton folder gluers is suitable for the folding of food, cosmetics and other small packaging carton. They focus on crease precision and product surface smoothness to meet the high aesthetic requirements of these products. Corrugated box folder gluers (folder gluers) mainly for corrugated cardboard made of cardboard, emphasizing bonding strength and compressive resistance. They can accommodate different flute types, such as A, B and C. Special-shaped box folder gluers can handle nonstandard folders, such as trapezoidal and hexagonal boxes. Equipped with custom folding mechanism to meet professional packaging needs.
INTRODUCTION In which industries are folder binders widely used? What are their strengths?
(I) Main Application Industries
folder gluers is widely used in the food and beverage industry to form packaging such as biscuit boxes, beverage boxes and cans. They meet strict hygiene standards for food packaging, while also adapting to efficient production.
The pharmaceutical industry is highly demanding of sealing and compliance with packaging standards. folder machine is suitable for processing of cartons of pharmaceutical and medical devices to ensure compliance with relevant standards.
In the daily chemical industry, cosmetics boxes, detergent packaging, skin care box all need exquisite appearance. Folder gluers provides precise adhesive for these products, ensures the beauty of the products and enhances the added value.
In the electronics and home appliance industry, electronic packaging box (such as mobile phone box, computer boxes, etc.) and external packaging boxes require a certain strength and protection. Folder gluers meet these requirements, balancing strength and appearance. With the rapid development of e-commerce, the logistics express industry needs more and more packaging. Folder gluers provide efficient gluing for express cartons and logistics packaging to meet the high volume, multi-format packaging demands of the e-commerce era.
(II) Core Advantages
Increasing productivity is one of the main advantages of folder gluers. Compared with manual gluing, automated folder gluers can achieve high speed continuous production, single machine can complete dozens to hundreds of boxes per minute, greatly shorten production cycles and improve overall production efficiency.
To ensure the consistency of the product, folder machine use precise mechanical positioning and parameter control to ensure that the adhesive positions and crease angles of each finished product are consistent, reduce errors caused by manual operation, and ensure more stable product quality.
In terms of reducing labor costs, folder gluers reduce reliance on manual labor, especially in mass production. This greatly reduces labour input and management costs, while also avoiding quality fluctuations due to fatigue.
Adapting to different needs is also a key advantage of Automatic folder gluer machine. By replacing mold and adjusting parameters, we can quickly adapt carton/ carton of different sizes and shapes to meet the needs of a variety of products and flexible production in small quantities. In addition, the folding machine can also improve packaging quality. Uniform adhesion and stable compression make sure that the adhesion is robust and that there is less degumming and deformation. It also makes sure that the package looks smooth and elegant, which helps the product's market. competitiveness.
