長興超聲波焊接機焊接時出現虛焊？這幾個原因你絕對想不到！

隨著人們生活節奏的加快和消費習慣的改變，一次性紙杯的需求保持穩定增長。特別是在快餐、咖啡連鎖店等消費場所不斷增加，以及外賣和外帶食品消費的持續升溫，一次性紙杯的市場規模不斷擴大。超聲波焊接無需使用粘合劑、扣釘或粘接劑等輔助材料，降低了對環境的汙染。此外，其能耗相對較低，僅爲電阻點焊的5%左右，且焊件變形小，有助于實現綠色生産。在當前環保意識日益增強的社會背景下，超聲波焊接技術符合可持續發展的要求，爲一次性紙質紙杯的環保生産提供了有力支持。

在超聲波焊接過程中，"虛焊"問題常常困擾著操作人員。它不仅影响産品的质量，还可能导致生产效率的降低。虚焊指的是焊接部位未能达到预期的牢固程度，甚至可能出现焊接点脱落的情况。本文将深入分析長興超聲波焊接機 焊接時出現虛焊的原因，並提供相應的解決之道，同時介紹設備故障維修流程。

超聲波焊接機焊接時出現虛焊的五大隱藏原因分析

材料含水率超標

許多用戶不知道的是，塑料顆粒或制品中過高的水分含量會在焊接時産生微氣泡，導致焊接面結合不牢。當材料含水率超過0.2%時，虛焊風險顯著增加。

模具共振頻率偏移

長期使用後，焊接模具的固有頻率可能發生0.5-1kHz的偏移，這與發生器輸出頻率不匹配，導致能量傳輸效率下降30%以上。

氣壓系統微泄漏

氣壓管路中不易察覺的微小泄漏會使焊接壓力波動超過標准值的±10%，這是造成焊接壓力不足的隱形殺手。

接地不良幹擾

不規範的接地會引入高頻幹擾，使控制信號失真度達到15%以上，直接影響焊接參數的精確執行。

環境溫濕度變化

當環境溫度超過35℃或相對濕度超過70%時，換能器轉換效率可能下降20-30%，這是夏季虛焊率升高的主因。

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
