1、 Core functions and technological advantages

Efficient automated unloading

The ton bag unpacking machine can quickly complete the entire process of lifting, positioning, bag breaking, and material placement of ton bags. The unloading time for a single bag is usually 1-3 minutes, which is 5-10 times more efficient than manual unpacking. The equipment supports continuous operation and is compatible with different specifications of ton bags (with a load capacity of 500-2000kg). Automatic loading of ton bags is achieved through devices such as electric hoists and lifting platforms, reducing the risk of manual handling.

Environmentally friendly and dust-proof design

In response to the problem of dust pollution that is easily generated during the unpacking process, the ton pack unpacking machine adopts a fully enclosed structure and is equipped with an efficient dust removal system. Sealing devices (such as rubber sealing rings and flexible curtains) are used at the interface between the discharge port and the ton bag to prevent dust from overflowing; The top is integrated with a pulse bag filter or negative pressure suction device, with a dust removal efficiency of over 99%, controlling the dust concentration in the workshop within the safety standard range (such as<10mg/m ³), protecting the health of operators, and complying with environmental regulations.

Safe and reliable operation

The equipment is equipped with multiple safety protection mechanisms: the electric hoist is equipped with anti fall locking mechanism and overload protection device to prevent the ton bag from falling; The operation interface is equipped with an emergency stop button and a safety light barrier to prevent personnel from accidentally touching it; For flammable and explosive materials, explosion-proof equipment (Ex certified) can be selected, using explosion-proof motors, explosion-proof control boxes, and anti-static materials to eliminate safety hazards.

Flexible adaptability

The unloading method can be customized according to the material characteristics (powder, particle, block) and downstream process requirements. For example, for materials with poor fluidity, built-in vibrators and arch breaking devices can assist in unloading; For high-precision measurement scenarios, it can be linked with weightlessness scales and spiral measuring devices to achieve quantitative feeding; Support seamless integration with downstream equipment such as pneumatic conveying and spiral conveying to meet different production line layouts.

2、 System composition and working principle

1. Core structural components

Ton bag processing unit

Lifting device: composed of electric hoist, sling, rotating hook, etc., it can achieve vertical lifting, horizontal movement, and 360 ° rotation of the ton bag, facilitating precise positioning of the ton bag. Some high-end models are equipped with automatic bag hanging robotic arms, further enhancing the level of automation.

Bag breaking mechanism: Common forms include manual cutting knives, automatic rotating bag breaking knives, tearing devices, etc. The automatic bag breaking knife is driven by a motor to rotate and quickly cut open the bottom or side of the ton bag, with neat cuts and smooth unloading.

Bracket and lifting platform: High strength steel bracket provides stable support, and the lifting platform (electric/hydraulic drive) can adjust its height to adapt to the feeding port position of different feeding equipment (such as silos and mixers).

Unloading and conveying unit

Unloading hopper: adopts a conical or flat bottom structure, with smooth inner walls (roughness Ra ≤ 0.8 μ m) to prevent material residue. For materials that are prone to clumping, built-in vibration motors, air cannons, or mixers are used to break down material bridges and ensure smooth unloading.

Gate control: Material flow can be controlled through manual butterfly valves, electric gate valves, or pneumatic knife gate valves to achieve discharge speed regulation and emergency material cut-off.

Conveyor interface: The bottom of the discharge hopper is equipped with a standard flange interface, which can be connected to screw conveyors, pneumatic conveying pipelines, belt conveyors, etc., to transport materials to designated locations.

Dust removal and environmental protection unit

Dust removal system: composed of a suction port, a fan, and a dust collector (such as a pulse bag dust collector). When unpacking, the fan generates negative pressure and sucks the dust generated during unloading into the dust collector for filtration. The purified air is then discharged or recycled for use; The dust collector supports automatic dust cleaning function, which removes dust on the surface of the filter bag through pulse blowing, ensuring continuous and efficient operation.

Sealing component: Elastic sealing material is used at the interface between the ton bag and the discharge hopper, forming a closed space during the discharge process to prevent dust leakage.

control system

PLC+touch screen: Operators can set lifting height, bag breaking speed, dust removal parameters, etc. through the touch screen; The system displays the real-time running status of the equipment, supports fault code alarms and historical data queries.

Remote monitoring function: Some models support IoT modules, which can remotely monitor device operation through mobile apps or computers, enabling remote fault diagnosis and parameter adjustment.

2. Workflow

Ton bag lifting: Hang the ton bag onto the electric hoist hook, start the lifting device to lift the ton bag above the discharge hopper and position it.

Bag breaking unloading: The automatic bag breaking knife cuts open the bottom of the ton bag, and the material falls into the unloading hopper under the action of gravity; If the material has poor fluidity, activate the vibrator or arch breaking device to assist in unloading.

Dust treatment: The dust removal system starts synchronously, and the negative pressure suction port absorbs the dust generated during the unloading process to ensure a clean working environment.

Material transportation: The materials in the discharge hopper are controlled by gates and transported to subsequent processes through downstream conveying equipment (such as screw conveyors).

Empty bag recycling: After unloading is completed, the electric hoist moves the empty bags to the designated location for recycling.

3、 Typical application scenarios

Chemical industry: used for unpacking and unloading of chemical raw materials such as polyethylene, polypropylene, carbon black, pigments, etc. The equipment can be made of stainless steel or rubber lining materials, suitable for corrosive materials; Explosion proof design meets the safety requirements for hazardous chemical production.

Food and pharmaceutical industry: Processing materials such as flour, starch, milk powder, pharmaceutical intermediates, etc. The parts in contact with the materials are made of food grade 304/316L stainless steel, with surface polishing treatment, in compliance with hygiene standards such as GMP and HACCP; Fully enclosed structure to prevent material contamination.

Plastic and rubber industry: used for unpacking and unloading plastic particles and rubber powders, coupled with measuring devices to achieve precise feeding and meet production process requirements.

4、 Technological development trends
