The installation techniques for conveyor belts mainly include the following steps and precautions:
1、 Preparation before installation
Check the rack:
Ensure that the rack is sturdy and has consistent diagonal lengths.
Check whether the brackets of each part of the body are deformed and correct them if necessary.
Check the rollers and pulleys:
Clean the foreign objects on the rollers and pulleys to ensure flexible rotation.
Check if the roller rotation is damaged and ensure there are no faults.
Check other components:
Check the integrity of the hopper and cleaner.
Ensure that the tensioning device moves flexibly and adjust the tensioning device to the shortest distance possible.
2、 Installation steps
Installation rack:
Install in the order of the first frame, then the middle frame, and finally the tail frame.
During installation, ensure that the center position of the conveyor is consistent and the longitudinal horizontal tilt angle is within the allowable range.
The error range of the single row frame to the centerline is controlled within ± 0.1mm, and the error of the frame center along the entire length of the conveyor is less than 35mm.
Install the driving device:
Ensure that the drive shaft is perpendicular to the centerline of the conveyor and that the centerline of the conveyor overlaps with the center of the drive drum width.
The transmission axis is parallel to the axis of the reducer.
Level all shafts and rollers to ensure good operation without load and power. The horizontal error range of the axis is within 0.5-1.5mm.
Install tensioning device:
At the same time as installing the drive device, a tensioning device can be installed.
Ensure that the centerline of the conveyor is perpendicular to the drum axis of the tensioning device.
Install the roller frame and upper and lower rollers:
After the installation of the frame, transmission device, and tensioning device, proceed with the installation of the roller frame and upper and lower rollers.
The conveyor belt should gradually form a curved arc shape, and the spacing between the roller frames in the bending section should be half of the normal roller frames.
After installation, ensure that the roller frame and rollers have sufficient flexibility and reliability.
Install conveyor belt:
Thread a flexible shaft onto the iron core of the conveyor belt and position the conveyor belt in the appropriate position. Pay attention to the working adhesive facing outward (i.e. the side with thicker adhesive).
In workplaces that are not suitable for shelving, the conveyor belt drum can be guided open, and the folded conveyor belt has a sufficiently large curvature radius to prevent damage. Do not place heavy objects at the fold.
If it is necessary to replace the conveyor belt, attach the new conveyor belt to the old conveyor belt and install it together. Ensure that the new and old conveyor belts are parallel to prevent deviation.
Align the position of the new belt on the conveyor, fix one end of the tape with a fixture, and then connect it to the rope that wraps around the drum and pulley. Use a traction device to maintain balance on the conveyor belt.
Fix one end of the conveyor belt onto the conveyor frame with a fixture, and tighten the other end with a pulley until there is no significant sagging of the conveyor belt on the return roller.
Secure the tensioning device at a distance of 100-150mm from the starting point.
3、 Debugging and inspection after installation
Debugging drum:
Ensure that all rollers are kept parallel and arranged in rows.
Correct the horizontal and center positions of the conveyor.
Debugging rollers:
Ensure that all rollers are kept horizontally parallel and arranged in rows.
Check for deviation phenomenon:
Belt deviation is a common fault during the operation of conveyor belts. After installation, the belt deviation phenomenon should be checked and adjusted.
The problem of belt deviation can be solved by installing a self-aligning roller group, adjusting the tensioning device, adjusting the position of the reversing roller and driving roller, and adjusting the position of the load-bearing roller group.
Other checks:
Arrange personnel to guard the conveyor belt in sections to prevent scratches and abrasions. Pay special attention to the state of the conveyor belt when passing through the drum and discharge port.
Regularly check the wear of the conveyor belt and replace severely damaged ones in a timely manner.
In summary, the installation techniques for conveyor belts include preparation before installation, installation steps, and debugging and inspection after installation. During the installation process, it is necessary to strictly follow the specifications to ensure the installation quality and service life of the conveyor belt.
输送带的皮带安装技巧主要包括以下步骤和注意事项：
一、安装前准备
-
检查机架：
- 确保机架坚固且对角线长度一致。
- 检查机身各部分支架是否变形，必要时进行校正。
-
检查托辊和带轮：
- 清理托辊和带轮上的异物，确保转动灵活。
- 检查托辊转动是否损坏，确保无故障。
-
检查其他部件：
- 检查料斗和清扫器的完好状况。
- 确保张紧装置移动灵活，并将调紧装置调到最短。
二、安装步骤
-
安装机架：
- 按照先头架、再中间架、最后尾架的顺序进行安装。
- 在安装过程中，确保输送机的中心位置一致，且纵向水平倾斜角度在允许范围内。
- 单排机架对中心线的误差范围控制在±0.1mm内，输送机全长上对机架中心的误差小于35mm。
-
安装驱动装置：
- 确保传动轴与输送机的中心线垂直，且输送机的中心线与驱动滚筒宽度的中央重叠。
- 传动轴线与减速器的轴线平行。
- 找平所有轴和滚筒，确保无负载和动力情况下的良好运行。轴的水平误差范围在0.5~1.5mm内。
-
安装张紧装置：
- 在安装驱动装置的同时，可以安装张紧装置。
- 确保输送机的中心线与张紧装置的滚筒轴线垂直。
-
安装托辊架和上下托辊：
- 在机架、传动装置和张紧装置安装完成后，进行托辊架和上下托辊的安装。
- 输送带应逐渐呈弯弧的形状，弯转段的托辊架间距为正常托辊架的一半。
- 安装完成后，确保托辊架和托辊具备足够的灵活性和可靠性。
-
安装输送带：
- 在输送带的铁芯上穿上转动灵活的轴，将输送带架在适当位置。注意工作胶面朝外（即面胶较厚的一面）。
- 在不适合上架的工作场所，可以将输送带卷筒导开，折叠处的输送带具有足够大的曲率半径，防止损坏。禁止在折叠处放置重物。
- 如果需要替换输送带，将新输送带附着到旧输送带上，一起进行安卸。确保新旧输送带平行，防止跑偏。
- 将新皮带在输送机上的位置对准后，用夹具固定胶带的一端，然后将其与绕过滚筒和滑轮的绳索连接起来。通过牵引装置使输送机上的输送带保持平衡。
- 将输送带的一端用夹具固定在输送机架上，另一端通过皮带轮拉紧，直到输送带在回程辊上没有明显下垂幅度。
- 在距起点100~150mm处固定好张紧装置。
三、安装后的调试与检查
-
调试滚筒：
- 确保所有滚筒保持平行状态，并排列成行。
- 校正输送机的水平位置和中心位置。
-
调试托辊：
- 确保所有托辊保持水平平行状态，并排列成行。
-
检查跑偏现象：
- 皮带跑偏是输送带运转过程中常见的故障。安装完成后，应检查并调整皮带跑偏现象。
- 可以通过安装调心托辊组、调整张紧装置、调整改向滚筒和驱动滚筒的位置、调整承载托辊组的位置等方法来处理皮带跑偏问题。
-
其他检查：
- 安排人员分段看守，防止输送带剐蹭、划伤。特别注意输送带通过滚筒、下料口时的状态。
- 定期检查输送带的磨损情况，及时更换破损严重的输送带。
综上所述，输送带的皮带安装技巧包括安装前准备、安装步骤以及安装后的调试与检查等多个方面。在安装过程中，需要严格按照规范进行操作，确保输送带的安装质量和使用寿命。
