Equipped with PLC intelligent control system and adjustable torque modules, the machine ensures consistent capping tightness, no loose caps, no slippage and no bottle damage. With compact layout, strong compatibility and ultra-low failure rate, it has become essential supporting equipment for high-speed filling and packaging assembly lines, perfectly solving the problems of low manual capping efficiency, uneven tightness and high defective rate in traditional production.
2. Core Main Features
2.1 Continuous Linear Inline Operation
This automatic linear screw capping machine adopts straight-line continuous conveying and capping mode, realizing non-stop cyclic production. The synchronous matching of conveyor belt and capping host eliminates intermittent pause time, greatly improving unit-hour output. The linear structure is easy to connect with front-end filling machines and back-end labeling machines, forming a fully automated integrated packaging line. It supports long-term 24-hour unmanned operation, fully meeting the mass production needs of medium and large factories.
2.2 Adjustable Constant Torque Capping Technology
Equipped with high-precision friction wheel capping mechanism and stepless torque adjustment system, the equipment can freely adjust capping tightness according to cap size and material hardness. It effectively avoids common problems such as cap sliding, cap cracking, excessive tightening and loose sealing. The constant-torque control ensures uniform capping effect for each batch of products, improving packaging consistency and product qualification rate to over 99.7%.
2.3 Wide Compatibility for Multiple Bottles and Caps
The linear capper features flexible structural adjustment, compatible with round bottles, flat bottles, square bottles and other conventional packaging containers. It adapts to screw caps of 15mm-70mm diameter, including cosmetic caps, detergent caps, beverage caps and pharmaceutical bottle caps. No need to replace molds for different specifications, realizing rapid switching of multi-specification production and greatly improving production flexibility for multi-variety processing enterprises.
2.4 Intelligent Anti-Error & Protection System
Built-in intelligent no-bottle-no-capping, missing-cap detection and overload protection functions. The machine will automatically pause and alarm when encountering empty bottles, missing caps or stuck bottles, effectively reducing material waste and equipment failure loss. The human-machine touch screen interface supports visualized parameter setting, production data statistics and fault self-diagnosis, with simple operation and low worker learning threshold.
2.5 Hygienic & Low-Maintenance Structure
The whole machine frame and material contact parts are made of food-grade 304 stainless steel, which is rust-proof, anti-corrosion and easy to clean, complying with GMP production hygiene standards. The optimized linear transmission structure has few vulnerable parts and stable operating performance. Daily maintenance only requires regular cleaning and lubrication, reducing long-term operation and maintenance costs for enterprises.

In the daily chemical industry, it is widely used for capping shampoo, shower gel, laundry detergent, hand sanitizer and household cleaning solution bottles. In the cosmetic industry, it perfectly matches the precise capping demands of skin lotion, essence, cosmetic toner and personal care products with strict appearance requirements. In the food and beverage industry, it applies to sauce, syrup, edible oil, fruit juice and condiment bottle sealing. In the pharmaceutical and chemical industry, it meets the hygienic and safe capping standards of medicinal liquid, disinfectant and mild chemical solvent bottles. Suitable for docking with various filling production lines, it supports both small-batch flexible production and large-scale assembly line mass production, covering most screw cap bottle packaging scenarios.
5. Product Core Advantages
Compared with traditional rotary capping machines and semi-automatic capping equipment, our linear screw capping machine has obvious competitive advantages. First, the linear inline structure realizes continuous high-speed production, with smoother operation and higher output efficiency than intermittent rotary equipment, and is more convenient for production line docking and layout adjustment. Second, the stepless adjustable constant torque capping system ensures zero bottle damage and uniform sealing tightness, effectively improving product packaging grade and reducing defective product loss. Third, the tool-free specification switching design greatly saves mold replacement time and improves production efficiency for multi-product factories. In addition, the equipment has low energy consumption and low failure rate, reducing labor dependence and long-term operating costs. The fully automated intelligent operation mode simplifies production management, helping enterprises achieve standardized and efficient packaging production.
