The hydraulic lock-door packaging machine is a type of horizontal hydraulic packaging machine. The discharge port of the machine body is equipped with a hydraulic automatic locking door mechanism. During compression, the door body is automatically locked, without expanding the box or losing material. After packaging is completed, the door opens automatically and the package is pushed out for discharge. It is a medium-sized fully automatic waste paper and plastic packaging equipment.
II. Core Function Hydraulic automatic door locking system, anti-expansion box and anti-spill material protection
During the compression process, the door body is hydraulically locked and can withstand high pressure without opening, leaking materials, or bulging. The resulting chunks are more compact and regular. High-pressure capacity reduction saves storage space and transportation costs.
Compress and reduce the volume of loose materials such as cardboard boxes, plastics, films, and woven bags by more than ten times. This reduces the space required for storage and saves logistics costs.
Semi-automatic / fully automatic operation, saving labor
The locking, pressurizing, opening, and bag pushing are all hydraulically controlled. One person can operate it, and it is suitable for recycling stations and factory solid waste workshops for long-term use.
Standard bag type, high recycling value
The locking limit is fixed, the size of the bag block is uniform, the density is uniform, and it does not disperse. It is convenient for weighing, loading, and selling at a high price.
III. Main Functions
Hydraulic automatic door locking function
Before compression, the oil cylinder automatically locks the discharge door. The locking force is strong, and it can resist the reverse thrust of high pressure, preventing door collapse, material leakage, and bulging.
Horizontal large-pressure hydraulic compression
The main oil cylinder is horizontally pushed and squeezed, with sufficient pressure, and both soft materials and light-bulbed materials can be compressed very firmly.
Automatic door opening + automatic bag pushing
After the packaging is completed, the hydraulic automatically unlocks the door, and the bag-pushing oil cylinder automatically discharges the bag. The cycle operation efficiency is high.
PLC electronic control one-button operation
Manual / automatic mode switching, one button can complete feeding - locking door - compression - holding pressure - opening door - pushing bag. It is simple and easy to operate.
Holding pressure and shaping function
When the compression is completed, it automatically holds pressure to prevent material rebound and ensures the stable and non-dispersed shape of the bag block.
Multiple safety protections
Hydraulic overload relief, motor overload, emergency stop protection, door power-off. The operation is safe.
Body sturdy and durable
The thickened steel plate welding, and the internal wear-resistant lining. It does not deform under high pressure for a long time and has a low failure rate.
IV. Applicable Materials
Waste paper, corrugated cardboard boxes, plastic bottles, plastic films, woven bags, non-woven fabric, clothing scraps, household waste solid waste, straw, etc. light-bulbed and loose materials.
V. Product Core Advantages
Hydraulic automatic door locking, no box expansion, no material leakage
The bag block has high density and regular shape, and the selling price is higher
The structure is stable, with a lower failure rate than simple mechanical door locks
Medium price, high cost performance, suitable for small and medium-sized recycling stations and factories for self-use
