The dog days patch four-side sealing packaging machine is a specialized automatic equipment designed for producing small, hygienic, and easy‑to‑use cooling patches. It adopts a four‑side sealed sachet structure, providing excellent protection for the gel or liquid inside and ensuring long‑term product stability during storage and transportation.This machine integrates film unwinding, printing cursor tracking, bag forming, material dosing, sealing, cutting, and counting into one continuous process. Packaging material, usually composite film with good barrier and heat‑sealing performance, is fed from the roll and precisely guided into the forming area. A vertical and horizontal sealing system then forms individual cavities while maintaining consistent pressure and temperature, resulting in neat and firm four‑side seals.The dosing system is designed to handle viscous or semi‑gel formulations, which are common in dog cooling patches. A high‑precision pump or piston filler dispenses a fixed volume into each formed pouch, ensuring uniform thickness and weight of the patch. This guarantees consistent cooling performance and comfort when the patch is applied to the animal’s body. Material contact parts are made from stainless steel and other food‑grade materials to meet hygiene and safety requirements.Temperature‑controlled sealing jaws complete the four‑side sealing process. The combination of accurate temperature control, pressure adjustment, and dwell time produces tight, wrinkle‑free seals that prevent leakage, contamination, and drying of the patch. After sealing, the continuous strip is cut into individual sachets or strips of multiple connected sachets according to product requirements. Easy‑tear notches can be added to the edges to allow pet owners to open the package effortlessly.An intelligent control system, usually based on PLC and a touch screen interface, coordinates the entire workflow. Operators can set bag size, filling volume, production speed, and sealing temperature on the screen. Fault alarms, production counting, and parameter memory help reduce downtime and improve operational efficiency. Photoelectric tracking ensures that printed patterns and cutting positions are accurately aligned, enhancing product appearance and brand image.The machine supports various formats, such as single‑lane or multi‑lane designs, to meet different capacity levels. A multi‑lane model can produce several rows of patches simultaneously, greatly increasing output and reducing labor costs. Compact structure and modular design facilitate installation, cleaning, and maintenance in a production workshop.With its high degree of automation, stable performance, and reliable sealing effect, the dog days patch four‑side sealing packaging machine is suitable for manufacturers of veterinary and pet care products who require standardized, high‑volume packaging of cooling patches for dogs during hot weather.
