PP 관통축 고무 롤러

Product Overview

The PP thru-axis rubber roller is a transmission component for PCB equipment. Its through-shaft arrangement supports the rotating roller along a continuous axis, providing a defined mounting structure for board conveying and transfer positions. In suitable wet-process installations, it can also help control cleaning water and process liquid as boards move between equipment sections.

Model 6-2 is available in white with acid and alkali resistance, a specified hardness of 90 to 105, heat resistance of 100 degrees C, and radial runout of 0.15 mm. Dimensions can be customized to match the working width, installation space, shaft ends, and drive connection of the machine.

Product Specifications

Main Product Features

– Through-shaft configuration provides a continuous axis for mounting and rotation. Shaft ends and drive interfaces should match the equipment drawing.

– Acid and alkali resistance supports operation in wet-process environments. Compatibility depends on the solution, concentration, temperature, and contact duration.

– The stated radial runout of 0.15 mm gives equipment designers and maintenance teams a defined reference for roller rotation and alignment.

– Heat resistance of 100 degrees C provides a temperature reference for selection. Confirm the intended continuous duty conditions before ordering.

– Custom dimensions allow the roller to be matched to the machine working width, mounting span, and replacement component.

– The white working surface allows visible deposits and surface damage to be identified during routine inspection.

Functions in PCB Processing Equipment

In a roller transmission system, the shaft receives motion from the machine drive and supports the roller as it contacts or guides the board. Matching the roller diameter, shaft-end geometry, and working length helps maintain the intended board path and speed. Bearing alignment and the condition of the drive connection also affect how smoothly the assembly runs.

Where the equipment uses the roller at a liquid-control position, the roller can help limit cleaning water or process solution from reaching neighboring sections. The actual result depends on the mating roller, contact pressure, board thickness, and surrounding tank geometry. Confirm both the conveying function and the liquid-control requirement when specifying the component.

Typical Applications

– Transmission and board conveying positions in PCB machinery

– Transfer positions between PCB processing modules

– Wet-process conveying sections that require acid and alkali resistance

– Combined conveying and liquid-control positions where the machine design permits

– Replacement roller assemblies for equipment maintenance

– Custom roller assemblies for PCB equipment manufacturers

사용자 지정 옵션

Roller size can be customized to the equipment requirements. Submit a drawing or dimension sheet showing the outer diameter, working-face length, overall length, shaft diameter, bearing positions, and shaft-end geometry. Include the details of any keyway, flat, thread, coupling, or other drive feature present on the original assembly so the connection can be reviewed.

For a replacement order, a sample or clear photographs of the complete roller and both shaft ends can help confirm the structure. The roller body specification, shaft material, drive arrangement, and any additional dimensional tolerances should be agreed before production. These details are particularly important when similarly named machines use different roller assemblies.

Selection Guidance

Start with the installation dimensions and drive connection. Then review board thickness, conveying speed, load, contact pressure, operating temperature, process liquid, and cleaning method. A roller that fits the bearing supports still needs the correct diameter and contact arrangement to work with the rest of the conveying system.

The specified hardness is 90 to 105. Confirm the hardness test method and acceptance requirement with the supplier when preparing the order specification. Chemical compatibility should also be evaluated under the actual operating conditions, especially for concentrated solutions, extended exposure, or service near the listed heat resistance.

Installation and Maintenance

– Check the dimensions and drive interface against the approved drawing before installation.

– Isolate the machine according to its maintenance procedure before removing or fitting the roller.

– Clean the bearing supports and mounting area to remove deposits that could affect alignment.

– Fit the assembly without bending the shaft or striking the working surface.

– Check free rotation, shaft alignment, drive engagement, and clearance from adjacent parts.

– Use the equipment manufacturer’s procedure to set roller contact and confirm board movement.

– Inspect for uneven wear, cracks, deposits, shaft damage, loose connections, and abnormal vibration.

– Clean with a method compatible with the roller assembly and replace damaged parts when conveying or liquid control is affected.

Quality and Order Confirmation

An approved drawing or confirmed sample provides the reference for a customized order. Specify the critical dimensions, shaft ends, working surface, hardness test method, and radial runout acceptance requirement. These points should be reviewed before production and included in the agreed inspection requirements.

Qixingyuan Machinery supplies accessories for PCB equipment. Send the existing roller drawing, sample information, and operating conditions to discuss product selection and dimensional customization. Clear technical information helps identify the required assembly and prepare a quotation that matches the installation.

Packaging and Delivery

Confirm packaging that protects the working surface and projecting shaft ends from impact and bending. For long assemblies, support along the packed length is important to prevent concentrated loads during handling. Discuss packing dimensions, quantity, delivery destination, and shipment requirements when requesting the quotation.

Information Required for a Quotation

– Model 6-2, equipment model, and installation position

– Outer diameter, working-face length, and overall length

– Shaft diameter, bearing positions, and shaft-end dimensions

– Drive connection drawing or photographs

– Drawing, dimension sheet, or existing sample

– Process liquid, concentration, temperature, and exposure duration

– Conveying speed, board thickness, load, and contact requirements

– Quantity, delivery destination, and requested delivery date

자주 묻는 질문

What does thru-axis mean?

It refers to a shaft that runs through the roller assembly. The shaft provides the mounting axis and can connect the roller to the equipment drive, depending on the machine design.

What is the main use of this roller?

Model 6-2 is intended for transmission in PCB equipment. It can be considered for board conveying, transfer, and suitable liquid-control positions after the installation requirements are confirmed.

Can the roller dimensions be customized?

Yes. Provide the roller dimensions, shaft-end details, drive connection, and a drawing or sample for confirmation.

What are the heat resistance and radial runout values?

The specified heat resistance is 100 degrees C and radial runout is 0.15 mm. Confirm the duty conditions and inspection requirements when placing the order.

What is the hardness?

The specified range is 90 to 105. The hardness test method and acceptance criteria should be agreed with the supplier.

Is it suitable for acidic and alkaline solutions?

The roller is specified as acid and alkali resistant. Provide the actual solution, concentration, temperature, and exposure duration so suitability can be reviewed.
