Definition
The bottle – turning device is an industrial equipment used for automatically turning bottles and cans on packaging production lines of beverages, alcoholic drinks, etc. It is mainly composed of components made of high – molecular nylon materials and a stainless – steel structure. Through its spiral inner – cavity structure, it can achieve multi – angle turning from 90° to 360°. This equipment uses self – lubricating and wear – resistant materials to reduce the scratching rate of containers. It can be seamlessly connected to the automated conveyor line, with a maximum hourly processing capacity of 2000 units. It is widely applied in the liquid packaging fields such as beer, carbonated beverages, and dairy products.
Product Structure and Materials
It adopts a composite structure of ultra – high molecular weight polyethylene (molecular weight ≥ 3.5 million) and 304 stainless steel. The contact surface is made of self – lubricating and wear – resistant PE material, and the main frame is made of reinforced nylon material. This combination of materials not only has an impact strength (≥ 50kJ/m²) but also exhibits corrosion – resistant properties. Compared with traditional iron – cage – type equipment, it reduces the container damage rate by approximately 75%.
Working Principle
The container is turned directionally through the spiral inner – cavity structure. The main working process includes:
After the container enters the spiral track, it is gradually tilted under the constraint of the guide plate.
Under the control of the track pitch and speed, it completes 90°/180°/360° turning.
After turning, it enters the next process through the conveyor belt at the end.
Technical Advantages
The equipment has the following innovative features:
Lubrication – free operation: The self – lubricating property of the high – molecular material reduces the maintenance frequency.
Modular design: The cage – like structure supports rapid disassembly, assembly, and cleaning.
Temperature adaptability: It can operate stably in an environment ranging from 45℃ to 180℃.
Power integration: There is no need for an external drive device, and it directly utilizes the kinetic energy of the conveyor line.
Industry Applications
It is mainly applied in the following production – line scenarios:
Beer production line: After bottle – body labeling, it is used for the turning inspection process. The bottle – turning device made of high – molecular nylon material supports customized turning angles of 90 degrees or 180 degrees.
Beverage filling line: It is used for 180 – degree or 360 – degree turning to inspect the tank’s sealing performance.
Dairy product packaging: It is used for 180 – degree inversion to check for residue at the bottle mouth.
Alcohol production: Customized 180 – degree or 360 – degree turning is used for the cleaning of special – shaped bottles.
Technical Improvement Plan
Material Innovation
The new – generation equipment uses ultra – high molecular weight polyethylene (UHMW – PE) with a molecular weight of over 3.5 million. Compared with traditional metal materials:
The coefficient of friction is reduced by 62%, enabling self – lubricating turning and eliminating scratches on the container surface.
The impact strength is increased by 3 times, and it can withstand 100,000 consecutive turning operations without deformation.
It has passed the FDA food – grade certification, avoiding the risk of metal – ion contamination.
Structural Optimization
The spiral inner – cavity structure is precisely manufactured by a CNC machining center and contains three innovative designs:
The variable – diameter spiral track can adapt to containers of different diameters, and the turning – angle deviation is controlled within ±1.5 degrees.
The modular splicing design shortens the maintenance time by 70%, and the weight of a single mold does not exceed 5kg.
The outer – sealing frame uses a SUS304 stainless – steel handle with a tensile strength of 520MPa.
