stretch hood machine

The stretch hood machine is a professional fully automatic cold stretch pallet packaging equipment, specially optimized for dry mortar production lines. It is mainly used for centralized packaging of palletized dry mortar bags, putty powder bags, refractory powder materials and other bulk building material products. Different from traditional winding wrapping and heat shrink packaging, this machine adopts advanced cold stretch hood technology. It automatically stretches the PE tubular film, covers the entire pallet cargo from top to bottom, and relies on the elastic retraction force of the film to tightly wrap the goods. It realizes integrated dustproof, waterproof, anti-loose and stable stacking packaging. With high packaging efficiency, low energy consumption and full sealing effect, it solves the problems of poor waterproof performance, loose stacking, easy dust contamination and high manual packaging cost of traditional mortar pallet packaging, and is the core supporting packaging equipment for standardized and intelligent dry mortar factories.

• Cold Stretch Packaging, Energy-Saving & Safe: Adopts pure cold stretching forming technology without heating system. It eliminates fire hazards and high energy consumption caused by heat shrink packaging, greatly reduces operation cost, and features safe and stable long-term operation, which is more suitable for building material production workshops with high environmental safety requirements.
• Full Sealing & All-Round Protection: The integral hood film fully covers the top and four sides of pallet goods, forming a completely closed protective layer. It effectively resists outdoor rain, dust, ultraviolet radiation and moisture erosion, perfectly solving the problem of mortar bag damp deterioration and dust pollution during storage and long-distance transportation.
• Superior Load Stability & No Collapse: The film features strong tensile resilience and uniform clamping force. It can tightly fit irregular stacked mortar pallets, fix loose packaging bags firmly, avoid cargo collapse and scattered materials during handling and transportation, and greatly improve pallet stacking stability.
• High Efficiency & Low Consumable Loss: One-piece film hooding replaces multi-layer winding packaging. The film replacement frequency is 10 times lower than that of traditional winding machines, which significantly saves PE film consumables. The fully automatic operation realizes fast hooding and packaging, greatly improving factory packaging efficiency and production throughput.
• High Automation & Labor Saving: Equipped with intelligent PLC control system and automatic film feeding, stretching, hooding and cutting functions. It supports unmanned continuous packaging, automatically adapts to pallet height and size changes, effectively saves manual packaging labor and reduces enterprise labor costs.
• Strong Adaptability & Wide Compatibility: Flexible adjustable packaging range, compatible with various dry mortar products such as masonry mortar, plastering mortar, thermal insulation mortar, waterproof mortar, as well as refractory materials and powder building materials. It can be perfectly connected with automatic palletizing production lines to realize fully automated packaging assembly line operation.

• Pre-Operation Inspection: Check the tightness of mechanical parts, the flexibility of film stretching mechanism and the integrity of sensor devices before startup. Confirm that the PE film is installed correctly without deviation or damage, and ensure no foreign objects inside the equipment operation area.
• Standard Pallet Placement: Ensure that the pallet goods are stacked neatly and stably, without serious inclination or oversize out-of-bounds. Avoid over-height and over-weight stacking to prevent failure of film stretching and hooding, or equipment jamming.
• Strict Film Selection: Must use special cold stretch PE tubular film matching the equipment. It is forbidden to use unqualified, too thin or damaged film, so as to avoid poor packaging tightness, film breaking and packaging failure.
• Safe Operation Management: It is forbidden to put hands, tools or sundries into the equipment working area during automatic operation. Non-professional personnel are not allowed to modify equipment parameters at will to avoid equipment failure and safety accidents.
• Daily Maintenance & Cleaning: Clean dust and residual sundries on the equipment surface and sensor parts daily to ensure sensitive induction and stable operation. Regularly lubricate transmission bearings and guide rails, and check the wear of stretching and cutting components.
• Fault Handling Rules: In case of film breaking, jamming, abnormal alarm or failed hooding during operation, stop the machine immediately for inspection and troubleshooting. Do not operate the machine with faults to prevent secondary damage to the equipment.
• Power Off Maintenance: Cut off the total power supply completely during equipment maintenance, film replacement and component replacement to ensure construction safety.

• Dry Mortar Production Industry: Special packaging for palletized finished products of masonry mortar, plastering mortar, bonding mortar, waterproof mortar, thermal insulation mortar and other dry mortar production lines.
• Building Powder Material Factory: Applicable to automatic sealing and packaging of putty powder, ceramic glue powder, floor mortar, concrete admixture and other powder building materials.
• Refractory & New Material Industry: Sealed packaging for refractory powder, silicon carbide powder, thermal insulation refractory materials and other industrial powder products to prevent moisture and dust pollution.
• Large Warehousing & Logistics: Suitable for outdoor stacking, long-distance transportation and container loading protection of palletized building materials, realizing all-weather storage protection.
• Intelligent Unmanned Factory: Matched with automatic palletizer and conveying line to form a fully automatic unmanned packaging production line, suitable for large-scale and standardized building material manufacturing enterprises.

• Q1: What is the difference between stretch hood machine and traditional winding wrapper?
  A1: The stretch hood machine adopts one-piece cold stretch full-cover sealing packaging, with better waterproof and dustproof effect, firmer cargo fixation and fewer film replacement times. It has lower comprehensive consumption and higher efficiency, which is more suitable for long-term storage and long-distance transportation of dry mortar products.
• Q2: Does the equipment need heating during operation?
  A2: No heating required. It adopts pure cold elastic stretching technology, with low power consumption, no fire risk and higher safety, which meets the safety production standards of building material factories.
• Q3: Can it adapt to pallets with irregular stacking of mortar bags?
  A3: Yes. The stretch film has strong flexibility and elastic retraction force, which can automatically fit irregular stacked cargo surfaces, effectively fix loose mortar bags, and keep the overall pallet stable and tidy.
• Q4: What kind of packaging protection effect can be achieved?
  A4: The whole pallet is fully sealed without dead angles, which can effectively prevent rainwater penetration, dust adhesion and ultraviolet aging. It keeps the internal mortar products dry and clean, and avoids quality problems such as damp and agglomeration of powder materials.
• Q5: Is the equipment easy to operate and maintain?
  A5: The equipment adopts intelligent PLC one-key operation, with simple operation and low manual dependence. The overall structure is stable with low failure rate, and daily maintenance is only regular cleaning and lubrication, with low later maintenance cost.
• Q6: Can the equipment be customized according to on-site pallet size?
  A6: Yes. We support personalized customization of pallet size, packaging height and production speed to meet the on-site production line layout and packaging needs of different dry mortar manufacturers.
• Q7: How to solve the problem of film breaking during packaging?
  A7: Film breaking is usually caused by unqualified film quality, incorrect film installation or excessive cargo out-of-bounds. It can be solved by replacing special stretch film, adjusting film installation position and standardizing pallet stacking specifications.
