How to buy a small carton factory

In recent years, the corrugated paper box industry has made great progress. The market demand has been increasing. Customers have also put forward higher requirements for the quality of carton boxes. Due to the low efficiency, large loss, multiple processes, and unstable quality of single-sided machines, they have gradually been eliminated. Many companies rush to use corrugated cardboard production lines. However, due to factors such as materials, orders, technology, and operations in production, some heavy-duty, large-scale high-speed production lines have failed to truly achieve efficient operation, resulting in overburdened enterprises and low efficiency, high consumption, and semi-discontinued production. Forced bankruptcy. For example, the heavy-duty production line at Changzhou Changzi Packing Co., Ltd. is a painful lesson. Therefore, small cartons in the purchase of the production line must be based on the company's implementation and future development space, combined with market demand, buy high quality, high efficiency, low consumption corrugated board production line.
1, do not blindly choose extra large, heavy high-speed line. Because of its mechanical complexity, it will increase the operation intensity and increase the loss. It will also lead to a high scrap rate due to small orders (less than 300 pieces). If some components are damaged and their technical strength is insufficient and they are forced to stop work for repair, the huge cost will lead to difficult operation. ·
2, before the purchase of equipment to mechanical equipment suppliers for comparison and analysis of the selection of a more powerful and reputable supplier, and make a good transport distance and after-sales service survey analysis, select a mature technology models. Because some dealers are driven by profits, when you do not fully understand the technical indicators, mechanical properties and how to properly configure the equipment, you will be recommended to you for immature products. Carton manufacturers must be calmly analyzed and carefully selected.
3. Enterprises should make reasonable choices based on their own strength and development. For example, some production lines with large amplitudes (2.2-2.5M) and high speed (250M/min) are affected by material limitations, technological deficiencies and other factors, resulting in high-speed lines reaching only moderate speeds. . In this way, rather than investing 6 million yuan to purchase a large-scale line, it would be better to invest 2 million yuan and 4 million yuan in phases to purchase two mid-range lines, which is more favorable to the company and less risky. With proper management and tacit understanding, the medium-speed production line can exert great benefits.
For example: WJ-120-1600 five-layer cardboard production line configuration:
Single-side machine: vacuum suction type; Corrugated roller diameter 320mm, core paper preheat cylinder diameter 900mm, 700mm, frequency conversion motor drive; 楞 type: B pit (48±0.5/300mm), BC pit (44±0 .5/300mm" tooth type: UV teeth; pneumatically cut into all rollers, electrically adjustable slurry thickness, high temperature grease lubrication.
Paper frame: hydraulic lift, retractable electric, pneumatic brake.
Coater: Touch bar device, electric adjustment paste thickness.
Bridge tension device: electric plywood, frequency control air flow.
Triple preheat cylinder: diameter 800mm angle adjustment.
Double-sided machine: heating plate 14 pieces, electric lifting, pneumatic tensioning, correction adjustment, main drive variable frequency motor.
Slitting machine: semi-automatic thin knife line trimming machine (with preloading device).
Computer cross cutting machine has two manual and automatic input functions, straight knife design.
Heat source: steam.
Paper output direction: left hand.
As can be seen from the above configuration, the production line has stable technical performance of medium and high-speed lines, and there are many aspects of energy-saving (saving electricity, paper-saving, section lubricants, saving tools, etc.), and the operation intensity is small, easy to maintain, adaptability Strong (base paper material) and other advantages.
