Welcome to Qingdao Yongke Machinery, a professional manufacturer with over a decade of experience in plastic machinery design and production. Since our establishment in 2010, we have been dedicated to providing reliable and efficient solutions for pipe manufacturing. Our Semi-Automatic PVC Pipe Extrusion Line with Haul-Off Unit and Stacker is engineered to streamline your production process, offering a balanced solution of automation and manual control for optimal flexibility and output. This integrated line is designed for manufacturers seeking to enhance their PVC pipe production with consistent quality and improved operational efficiency.
This production line represents a cohesive system where each component works in harmony. The extrusion process is precisely controlled, and the integrated haul-off unit ensures consistent pulling force for uniform pipe dimensions. The stacker automates the final handling stage, reducing labor intensity and minimizing product damage. The semi-automatic design allows for crucial operator oversight and intervention where needed, making it suitable for various production environments and skill levels.
Core Components & Integrated Workflow:
- Extruder: The heart of the line, equipped with a precision screw and barrel designed for optimal PVC compound plastication and stable melt pressure.
- Die Head & Sizing Sleeve: Customizable tooling that defines the final pipe's outer diameter and wall thickness with high accuracy.
- Vacuum Sizing Tank: Utilizes a vacuum calibration system to precisely size and cool the extruded pipe, ensuring dimensional stability from the start.
- Haul-Off Unit: A critical component featuring synchronized caterpillar haul-offs. It provides a steady, adjustable pulling force that matches the extrusion speed, preventing pipe stretching or deformation.
- Cutting Saw: An automatic traveling saw that cleanly cuts the pipe to pre-set lengths with minimal burrs.
- Stacker/Bundler: The final unit that automatically collects, counts, and stacks the cut pipes into neat bundles, ready for palletizing or further handling.
Key Technical Advantages & Specifications:
The line's performance is built on robust engineering. The extruder features a DC drive system for smooth speed control and a hardened screw for durability with abrasive PVC compounds. The PLC-based control panel centralizes operation, allowing for parameter setting, monitoring, and fault diagnosis. The haul-off unit employs multiple rubber-padded belts to grip the pipe firmly without marking its surface.
Typical Configuration Table (Parameters can be customized):
| Parameter | Description / Range |

Benefits for Your Operation:
- Consistent Product Quality: The synchronized haul-off and stable extrusion minimize wall thickness variation and ovality, producing pipes that meet stringent specifications.
- Reduced Labor Dependency: The automated haul-off, cutting, and stacking significantly reduce the number of operators required per shift compared to fully manual lines.
- Enhanced Production Safety: Enclosed cutting areas and automated handling minimize direct worker contact with moving parts and cutters.
- Improved Floor Space Utilization: The integrated, linear design is compact, allowing for efficient factory layout planning.
- Operational Flexibility: The semi-automatic control allows easy changeovers for different pipe sizes and recipes, supported by manual fine-tuning where necessary.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a semi-automatic line over a fully manual one?
A: A semi-automatic line significantly boosts productivity and consistency by automating the most repetitive and critical tasks—like pulling, cutting, and stacking—while retaining operator control for supervision and changeovers. This leads to higher output with less physical labor and fewer quality inconsistencies. -
Q: Can this line produce pipes of different diameters?
A: Yes, the line is designed for changeover. By switching the die head, sizing sleeve, and adjusting the haul-off caterpillar spacing and speed parameters, the line can be set up to produce a range of pipe diameters within its designed capacity. -
Q: How does the haul-off unit ensure the pipe is not damaged or marked?
A: The haul-off unit uses caterpillar tracks lined with special rubber pads. The clamping pressure is evenly distributed and can be precisely adjusted to provide sufficient grip for pulling without causing indentations or scratches on the PVC pipe's surface. -
Q: What kind of training or technical support is provided with the machine?
A: We provide comprehensive operational and maintenance manuals. Furthermore, we offer installation guidance and on-site or remote training for your operators. Ongoing technical support is available to assist with any operational queries. -
Q: Is the cutting length fixed, or can it be programmed?
A: The cutting length is fully programmable via the PLC control panel. You can set and store multiple cutting length profiles for different production orders, allowing for quick changeovers between standard lengths like 4m and 6m, or any other required length. -
Q: What is the typical output capacity of this line?
A: Output capacity depends heavily on the pipe diameter and wall thickness. For example, for a 110mm diameter pipe, a well-configured line can achieve an output in the range of 200-350 kg/hour. We can provide more specific capacity estimates based on your target product specifications. -
Q: How is the line cooled, and what utilities are required?
A: The primary cooling is done through a vacuum sizing tank and a subsequent water bath, which require a chilled water circulation system. The plant needs to supply adequate electrical power (as per the configuration), compressed air for pneumatic components, and process water.
