Bucket washing

Linear type bucket washing machine 

Bucket infeeding

The fully automatic barrel loading and unloading system features a single-station, cylinder-actuated flip design. It incorporates a proprietary "level-in, level-out" structural mechanism-developed in-house by our company-that effectively eliminates common issues such as misaligned loading, failure to unload, jamming during inversion, and excessive noise.
The system is equipped with a set of evenly spaced stopper blocks; the spacing between these blocks is adjustable, ensuring precise positioning and separation of the barrels. The loading and unloading flip plates feature a V-shaped, perforated structure designed to maintain high structural strength while simultaneously reducing overall weight and minimizing operational resistance. Empty barrels are conveyed to this mechanism via a conveyor belt; a pneumatic pusher cylinder then advances the barrel into the designated slot between the stopper blocks. Subsequently, a pneumatic flip cylinder rotates the mechanism upward to align with the bottle-holding cradle of the washing machine, at which point the pusher cylinder drives the barrel into the cradle. During the unloading phase, the flip mechanism receives the empty barrel; the pusher mechanism then clears the barrel to prevent jamming or failure to descend. Finally, the flip mechanism rotates back down toward the conveyor belt, and the pusher mechanism drives the barrel onto the output conveyor chain for discharge.

Internal Washing and Disinfection Machine

1. Equipment Components:
The machine consists of an alkaline cleaning section, a disinfectant cleaning section, a circulating water tank, a rinsing pump, a rinsing system, a cap-placing device, a capping device, a transmission system, and an electrical control system.
2. Working Principle:
Buckets that have undergone external cleaning are conveyed by the bucket-loading machine to the loading station within the rinsing section. Upon detection and counting by a photoelectric sensor, a single bucket is admitted, while a blocking cylinder holds back the remaining buckets outside the loading station. A push cylinder on the bucket-loading machine pushes the bucket onto a tilting frame, which then rotates the bucket into a horizontal position. Once the tilting cylinder reaches its designated position, a lifting cylinder pushes the bucket into a bucket-holding seat. As the conveyor chain rotates upward by 90 degrees, the plastic bucket transitions from its initial horizontal orientation to an inverted, vertical position-with its opening facing downward-and enters the cleaning stations for alkaline solution, disinfectant, and sterile water.
After being thoroughly rinsed and disinfected, the bucket is transferred by a shifting mechanism to the filling station. Once the bucket is in place, a filling cylinder activates to lower a positioning mechanism, which clamps onto the bucket's neck. The filling pump starts, the filling valve opens, and the filling process begins; the valve closes automatically once the preset filling time has elapsed. Upon completion of the filling process, the positioning mechanism retracts upward, and the conveyor motor activates to drive the conveyor belt, pulling the filled bucket away from the filling station. As the bucket travels along the conveyor belt, a cap-placing device places a cap onto it, and a capping head automatically presses it firmly into place. The clamping force of the capping head can be adjusted by regulating the compressed air pressure via a pressure-reducing valve. At this point, the entire filling and capping process is complete.

Cap washing and infeeding machine 

The cap sorter is equipped with a detection switch; when the supply of caps within it drops to a certain level, the switch triggers a signal to activate the cap feeder, which then replenishes the supply. The cap hopper holds a specific quantity of caps; under the action of a vibrating motor, a vibrating plate shakes the caps loose, feeding them onto a conveyor belt that transports them to the cap sorter. Once aligned by the sorter, the caps proceed into the cap washer, where they undergo a sequence of disinfection rinses and final rinses with purified water, before being conveyed via an enclosed guide chute into the capping machine.

Light detection

The product features an ultra-thin structure-less than 5 cm in thickness-and is integrally molded to ensure resistance to both water and corrosion.
The light source operates at a safe working voltage of 24V DC, ensuring safe, stable, and reliable performance.
The light-emitting surface provides uniform illumination free of any dark spots, with a light intensity uniformity ratio exceeding 0.95.
It boasts a long service life; the LED light source lasts for 50,000 hours-more than ten times the lifespan of standard fluorescent lamps.
Environmentally friendly and energy-efficient, it consumes over 60% less energy compared to traditional fluorescent lighting.
Highly versatile in application, it can be seamlessly integrated into production lines or utilized as a standalone unit.
It is particularly effective for specialized inspections involving color, turbidity, leaks, and visually detectable foreign matter.
