Bottom-feeding Film Pillow Packaging Machine

This Bottom-feeding Film Pillow Packaging Machine is equipped with original Japan Panasonic high-performance frequency converter and AC driving motor to realize full-range stepless speed regulation, bringing flexible and efficient production scheduling for diversified orders. Unlike fixed-gear speed shifting of ordinary packaging machines that causes unstable startup and material jitter, the Panasonic frequency conversion system delivers smooth and linear speed adjustment without stalling or abrupt acceleration/deceleration. Operators can freely adjust the packaging speed within the corresponding range of each model via the touch screen according to material softness, film thickness and daily output targets. Cooperated with high-precision photoelectric tracking and PLC linkage control, the machine always maintains synchronous matching between feeding speed and sealing speed during speed increasing or decreasing. It not only avoids material dislocation and packaging film waste caused by speed fluctuation, but also prolongs the service life of transmission gears and motors, perfectly adapting to frequent speed switching for small-batch and multi-specification flexible material production.

Anti-scald Protection While Stopping

Aiming at the common problem of packaging film burning and scrapping when traditional horizontal wrappers stop unexpectedly or pause manually, Huaze adds an upgraded positioning stop anti-scald function to this Bottom-feeding Film Pillow Packaging Machine. During temporary shutdown, material replacement or emergency pause, the intelligent PLC system will automatically control the longitudinal and transverse sealing knives to quickly separate from the packaging film surface, instead of keeping high-temperature heating parts statically attached to the film. This core function fundamentally eliminates the risk of local overheating, film melting and scorching marks caused by long-time static baking of heat-sealing components. Combined with independent temperature control logic, the system can automatically suspend heating according to the running state. This humanized design effectively reduces defective products and raw material loss during frequent start-stop operations, lowers the comprehensive production cost of flexible film packaging, and also protects the heating sealing assembly to reduce wear and tear.

Core Technical Parameters

Product Application Scope

Benefiting from the unique upper longitudinal sealing design that minimizes extrusion force on packaged goods, this Bottom-feeding Film Pillow Packaging Machine is exclusively positioned for bulk, long-strip and flexible materials without front-back orientation, which cannot be perfectly packaged by ordinary down-seam pillow machines. In the food industry, it is widely used for packaging bread sticks, sausage, energy bars, vermicelli, strip-shaped candies and various flexible baked snacks; in the daily necessities industry, it applies to disposable mask strips, sponge strips, flexible rubber hoses and long beauty accessories; in the hardware and accessory industry, it can package sealing strips, flexible cables, plastic strips and other non-rigid long-strip parts. Equipped with an adjustable bag former and one-key size switching function, this machine can quickly respond to multi-specification packaging demands and maximize material yield for flexible products.

Frequently Asked Questions

Q1: What is the core advantage of bottom-feeding structure compared with standard pillow machines?

A: Standard pillow machines adopt bottom longitudinal sealing which easily squeezes and deforms soft long-strip products. Our bottom-feeding design places the longitudinal sealer on the top of packages, which greatly buffers heat sealing pressure. It effectively prevents surface indentation and deformation, the best solution for flexible and unoriented bulk materials.

Q2: How does the photoelectric tracking system work for printed film?

A: The high-precision color mark electric eye cooperates with Panasonic PLC and bidirectional compensation mechanism to monitor offset in real time. The system automatically corrects left-right deviation during film operation to ensure consistent cutting position, error controlled within ±1mm, suitable for customized printed color films.

Q3: Is it easy to change packaging sizes for different products?

A: Extremely simple. Operators only need to input target bag length on the touch screen, and the system will automatically adjust relevant parameters. Matched with tool-free adjustable bag former, workers can finish size replacement within 5 minutes without professional debugging experience.

Q4: What benefits does the anti-scald stop function bring to mass production?

A: When the machine stops or pauses, the heating seal knives will separate from the film automatically to avoid static high-temperature burning. It drastically reduces film waste during frequent start-stop operations and lowers your material scrap cost in daily production.

Q5: How to select the correct model among HZ-260 to HZ-600?

A: We suggest selecting model according to product height and maximum packaging width. HZ-260/350 for small-size strip snacks; HZ-450/600 for oversized long-strip goods. You can send your product dimension and required output, and we provide free model selection service.
