中空玻璃加工设备：打胶机机头升降链条松动？这样调节精准又牢固

　　Hollow glass processing equipment: Is the lifting chain of the glue machine head loose? This adjustment is precise and firm

　　在中空玻璃加工设备中，打胶机是保障密封质量的核心设备，而机头升降链条则是控制机头精准升降的关键传动部件。一旦链条出现松动，很容易导致机头升降不稳、定位偏差，进而出现打胶线条歪斜、胶量不均等问题，严重时还会加剧部件磨损，影响设备使用寿命。不少一线操作人员面对这种情况容易慌神，其实只要找对调节部件、按规范步骤操作，就能轻松解决。今天就专门科普这一实用技巧，详细说说打胶机机头升降链条松动后的调节方法。

　　In the hollow glass processing equipment, the gluing machine is the core equipment to ensure the sealing quality, and the head lifting chain is the key transmission component to control the precise lifting of the head. Once the chain becomes loose, it can easily lead to unstable lifting and positioning deviation of the machine head, resulting in skewed glue lines and uneven glue volume. In severe cases, it can also exacerbate component wear and affect the service life of the equipment. Many frontline operators tend to panic when faced with this situation, but in fact, as long as they find the right adjustment components and follow the standard steps, they can easily solve it. Today, we will specifically popularize this practical technique and explain in detail the adjustment method for the loosening of the lifting chain of the glue machine head.

　　先跟大家理清核心调节逻辑：打胶机机头升降链条的松紧度，主要靠两组核心部件控制——两颗调节螺丝和四颗调节螺帽。调节的关键是通过有序拧动螺帽和螺丝，逐步收紧链条，最后将部件锁死固定，避免后续运行中因振动再次松动。整个过程不用复杂工具，重点在于把控操作顺序和力度，新手也能快速上手。

　　First, let me clarify the core adjustment logic: the tightness of the lifting chain of the glue machine head is mainly controlled by two sets of core components - two adjustment screws and four adjustment nuts. The key to adjustment is to tighten the chain gradually by turning the nuts and screws in an orderly manner, and finally lock and fix the components to avoid loosening again due to vibration during subsequent operation. The entire process does not require complex tools, the focus is on controlling the sequence and intensity of operations, and even beginners can quickly get started.

　　第一步，初次调节螺帽，初步张紧链条。先找到机头升降链条对应的调节部件，明确上下两组螺帽的位置。操作时先将下方的调节螺帽往下拧，直到链条达到初步张紧状态后停止；接着把上方的调节螺帽也往下拧，紧紧贴合下方部件做好定位备注。这一步的目的是通过上下螺帽的配合，先把链条的基础松紧度调到位，为后续精准微调打下基础，注意拧动时力度要均匀，避免损坏螺纹。

　　The first step is to adjust the nut for the first time and initially tighten the chain. First, locate the adjustment component corresponding to the machine head lifting chain and clarify the positions of the upper and lower sets of nuts. When operating, first tighten the adjusting nut below until the chain reaches the initial tension state and then stop; Next, tighten the adjusting nut on top and make a positioning note by tightly fitting it to the lower part. The purpose of this step is to adjust the basic tightness of the chain to the correct position through the coordination of the upper and lower nuts, laying the foundation for precise fine-tuning in the future. Pay attention to the even force when twisting to avoid damaging the threads.

　　第二步，二次微调，应对残留松动。完成初次调节后，建议启动设备测试机头升降情况。如果发现链条仍有松动，就进行二次微调：先找到侧边对应的调节螺丝，将其往下调，逐步收紧链条；同时同步调整上下两颗调节螺帽——把上方的调节螺帽往上拧，下方的调节螺帽也往上拧，直到链条松紧度达到理想状态。这里要提醒大家，调节螺丝时幅度要小，避免一次调得过紧，导致链条受力过大磨损或断裂。

　　Step two, secondary adjustment to deal with residual looseness. After completing the initial adjustment, it is recommended to start the equipment and test the lifting and lowering of the machine head. If the chain is still loose, perform a secondary adjustment: first find the corresponding adjustment screw on the side, adjust it downwards, and gradually tighten the chain; Simultaneously adjust the upper and lower adjustment nuts - tighten the upper adjustment nut upwards and the lower adjustment nut upwards until the chain tightness reaches the desired state. Here, we would like to remind everyone to adjust the screw with a small amplitude to avoid tightening it too tightly at once, which may cause the chain to wear out or break due to excessive force.

　　第三步，螺帽抱死，固定调节效果。当链条调整到合适松紧度（机头升降平稳无晃动、链条无明显下垂）后，关键一步是将两颗调节螺帽“抱死”。用工具将上下两颗螺帽相互拧紧，让两者紧密贴合、无法相对转动，这样就能牢牢锁定调节后的位置，防止设备运行中因振动导致螺帽松动、链条移位。最后再测试一次机头升降，确认无异常后，调节工作就完成了。

　　Step three, lock the nut and fix the adjustment effect. After adjusting the chain to the appropriate tightness (the machine head rises and falls smoothly without shaking, and the chain does not sag significantly), the key step is to "lock" the two adjustment nuts. Use tools to tighten the upper and lower nuts to each other, making them tightly fit and unable to rotate relative to each other. This will firmly lock the adjusted position and prevent the nuts from loosening or the chain from shifting due to vibration during equipment operation. Finally, test the head lifting again, and after confirming that there is no abnormality, the adjustment is completed.

　　这里给大家补充几个实操中必须注意的要点：一是调节前必须先断电并锁定设备，避免机头意外升降造成安全事故；二是调节过程中可以反复手动拉动链条或测试机头升降，确保松紧度适中，过松会影响定位，过紧则会加剧部件磨损；三是如果对调节力度没把握，建议用扭矩扳手辅助，避免过度用力损坏部件。另外，日常维护也很关键，建议每次开班前检查链条松紧度，定期给链条添加润滑油，减少磨损。

　　Here are a few key points that must be paid attention to in practical operation: firstly, power off and lock the equipment before adjustment to avoid safety accidents caused by accidental lifting of the machine head; Secondly, during the adjustment process, the chain can be manually pulled repeatedly or the machine head can be tested for lifting and lowering to ensure that the tightness is moderate. If it is too loose, it will affect positioning, and if it is too tight, it will exacerbate component wear; Thirdly, if you are unsure about the adjustment force, it is recommended to use a torque wrench to assist and avoid damaging the components due to excessive force. In addition, daily maintenance is also crucial. It is recommended to check the tightness of the chain before each shift and regularly add lubricating oil to the chain to reduce wear and tear.

　　其实打胶机的很多小故障，都能通过规范的调节操作解决，机头升降链条松动就是典型例子。对中空玻璃生产企业来说，一线操作人员掌握这类基础维护技巧，不仅能快速解决故障、减少生产线停摆时间，还能延长设备使用寿命、降低维护成本。希望这次科普能帮到大家，在日常操作中更好地应对打胶机的各类小问题，让生产更高效、产品更优质。如果调节过程中遇到具体疑问，也可以结合设备说明书或向有经验的师傅请教。

　　In fact, many small faults of the glue machine can be solved through standardized adjustment operations, such as loose lifting chains of the machine head. For insulated glass production enterprises, frontline operators who master these basic maintenance skills can not only quickly solve faults and reduce production line downtime, but also extend equipment service life and reduce maintenance costs. I hope this science popularization can help everyone better deal with various small problems of glue machines in daily operation, making production more efficient and products of higher quality. If you encounter specific questions during the adjustment process, you can also refer to the equipment manual or consult an experienced technician.
