2. Unique Processing Technology & Core Design Logic
The biggest difference between professional BOPP tape processing equipment and ordinary film slitting machines lies in the targeted adaptation to adhesive materials. The surface of BOPP tape is covered with pressure-sensitive adhesive, which is prone to friction damage, glue residue, edge burrs and degumming during processing. This machine adopts a set of exclusive industrial processing technologies to avoid all common quality problems of finished tapes.
In terms of slitting technology, it adopts physical shear cutting principle with upper and lower staggered tooth cutters. The cutting process is pure shear separation without friction and extrusion on the adhesive layer. It completely avoids the "angel hair" edge, glue overflow and edge warping caused by blade cutting. The finished tape edge is smooth, flat and free of debris, which meets the high-standard packaging and sales requirements.
In terms of transmission and forming, the machine adopts hierarchical anti-deformation control logic. Aiming at the problem that thin BOPP film is easy to stretch and wrinkle, the whole machine is divided into independent tension control areas. The system dynamically adjusts the operating speed and tension value of each link in real time according to the film operation state, ensuring that the film is always in a stable stress state, without stretching deformation and fold defects.
In terms of winding forming, the dual-drum pressure uniformizing design is used to replace the single-shaft winding of traditional equipment. The uniform rolling pressure can exclude the air inside the tape roll, make the roll body tight and round, effectively prevent the finished tape from loose rolling, hollowing and telescopic deviation, and greatly improve the appearance grade and storage stability of the product.
3. Modular Functional Configuration & Practical Production Value
3.1 Heavy-Duty Intelligent Unwinding Module
Equipped with thickened heavy-duty unwinding frame, it stably supports 1.5-2.5m wide ton-level BOPP jumbo rolls. The servo brake tension system realizes stepless adjustable unwinding tension, adapts to different grammage and viscosity BOPP films, and ensures synchronous and stable material release. The built-in material residual monitoring sensor automatically judges the material consumption status, provides early warning for roll replacement, and lays the foundation for non-stop continuous production.
3.2 Zero-Speed Non-Stop Splicing Module
As a core efficiency-enhancing module, the zero-speed splicing unit realizes seamless docking of new and old raw rolls. When the jumbo roll is about to be used up, the system automatically completes positioning, fitting and bonding of the film head and tail in a static state, and automatically resumes high-speed production. The whole process does not stop the machine, does not waste raw materials, completely solves the capacity loss caused by frequent shutdown and roll change of traditional equipment, and increases the comprehensive production efficiency by more than 35%.
3.3 Servo Automatic Positioning Slitting Module
All slitting cutters are driven by independent servo motors, supporting intelligent one-click width setting. The operator only needs to input the required finished tape width on the HMI touch screen, and the system automatically completes high-precision positioning and locking of all cutter groups. It eliminates manual measuring, calibrating and debugging links, shortens the order switching time from half an hour to 2-3 minutes, and is very suitable for multi-specification alternating production.
3.4 Duplex Alternating Cycle Rewinding Module
Dual-station rewinding shaft design realizes the separation of winding production and blanking replacement. During the production of one station, the other station can complete the unloading of finished logs and the replacement of new paper cores. After a single batch of production is completed, the equipment automatically switches the film to the standby station for continuous production. The alternating cycle work realizes 24-hour uninterrupted production and maximizes the utilization rate of the equipment.
3.5 Automatic Log Blanking & Fixed-Size Cutting Module
After the rewinding roll reaches the preset diameter and length, the equipment automatically stops stably. The electric ejection device integrally pushes out the multi-strip combined tape log, and the high-precision circular saw performs constant-speed transverse cutting. The cutting size is accurate, the incision is smooth, and no manual secondary trimming is required. The finished product can be directly packaged and sold, realizing one-stop processing from raw materials to finished products.

5. Production Operation Flow
The equipment adopts standardized and streamlined operation flow, with high automation and simple manual intervention. First, use forklift or crane to fix the BOPP adhesive jumbo roll on the unwinding frame, and install standard paper cores on the duplex rewinding shaft. After the equipment is powered on, the system performs self-inspection of tension, deviation correction and cutter status. The worker sets the finished tape width, rolling diameter and operating speed through the touch screen, and completes automatic film threading.
In the formal production stage, the equipment runs at a constant high speed, and the shear cutter group completes fixed-width slitting of the wide film. The tension control system ensures stable film transmission throughout the whole process, and the deviation correction device avoids film deviation. The slit tape is wound and formed through the dual-drum winding mechanism. When the raw material roll is nearly exhausted, the automatic splicing system completes non-stop roll change to continue production.
After the finished roll reaches the standard specification, the equipment automatically switches the station, ejects the finished log, and completes fixed-size cutting through the automatic circular saw. The worker only needs to collect and package the finished products, and the equipment immediately enters the next production cycle, realizing efficient cyclic processing.
6. Professional FAQ
Q1: What quality problems of traditional tape machines can this equipment solve?
It effectively solves common industry problems such as rough tape edges, burrs and glue residue caused by razor slitting, loose and deformed tape rolls caused by unstable tension, low output caused by frequent shutdown roll change, and large quality difference of finished products caused by manual debugging, greatly improving product qualification rate.

Yes. The high-precision servo positioning and stable tension control system can perfectly process printed patterned BOPP tapes. It will not cause pattern distortion, deviation and stretching, ensuring consistent printing position and beautiful appearance of finished printed tapes.
Q3: What is the labor cost advantage of fully automatic configuration?
Traditional semi-automatic equipment requires 2-3 workers to operate one machine, while this intelligent equipment only needs one worker to manage multiple units, mainly responsible for feeding and finished product collection. It greatly saves factory labor costs and reduces manual management pressure.
Q4: Why does dual-drum rewinding improve the quality of tape rolls?
The dual-drum structure provides uniform and stable contact pressure. During high-speed winding, it can completely exclude the air between tape layers, avoid air bubble gaps, make the tape roll tight and solid, prevent loose unwinding during use, and improve the storage cycle of finished tapes.
