44、進(jìn)的意大利生產(chǎn)的貼標(biāo)機,由于該貼標(biāo)采用了三個標(biāo)簽臺來完成頭標(biāo)、身標(biāo)、頸標(biāo)、背標(biāo)、頂帽標(biāo)的貼標(biāo)功能,其大轉(zhuǎn)盤槽凸輪設(shè)計上是托瓶盤在進(jìn)瓶與出瓶全過程中,轉(zhuǎn)角次數(shù)增加,槽凸輪易磨損且貼標(biāo)效果不理想。在貼標(biāo)功能不變的前提下,由南海平航機械廠改為兩個標(biāo)簽臺,槽凸輪選材上采用球墨鑄鐵,凸輪曲線設(shè)計上采用了拋物線過渡設(shè)計,使其運行更平穩(wěn),貼標(biāo)效果明顯改善,槽凸輪工作面更耐磨,使用壽命延長。</p><p>  (2)將原貼標(biāo)機

45、的標(biāo)掌軸、膠轆軸與膠刀軸用同一塊頂蓋連接在一起,使其運轉(zhuǎn)過程中更穩(wěn)定,保證了貼標(biāo)效果的穩(wěn)定性。同時標(biāo)掌軸裝夾位采用了便捷式,更換其它瓶子直徑和標(biāo)紙方便、快捷,適用大生產(chǎn)多種品種的要求。 (3)將膠刀分為上下兩段,用兩個汽缸控制,可分別調(diào)節(jié)上下標(biāo)的膠水厚度,即減少了膠水用量,又提高了貼標(biāo)合格率。</p><p>  5.國產(chǎn)仿西德貼標(biāo)機改造723-15-4-6 型貼標(biāo)機進(jìn)行改造,因其只有一個標(biāo)簽臺,功能上只

46、能貼頸標(biāo)和身標(biāo),功能有限,為增技改貼標(biāo)機的貼標(biāo)功能,南海平航機械廠作了如下改造。 (1)增添一個背標(biāo)標(biāo)簽臺,增添了頭標(biāo)裝置及標(biāo)刷,大轉(zhuǎn)盤槽凸輪相應(yīng)改換。具有貼頭標(biāo)、頸標(biāo)、身標(biāo)、背標(biāo)、頂帽標(biāo)的功能,使雙標(biāo)貼標(biāo)機功能上升為無標(biāo)貼標(biāo)機功能,與國際接軌。 (2)主標(biāo)簽臺標(biāo)掌軸由 4 件增加為 8 件,數(shù)量增倍,標(biāo)掌轉(zhuǎn)速相應(yīng)降低,使貼標(biāo)穩(wěn)定性更好。由于標(biāo)掌軸、夾標(biāo)轉(zhuǎn)鼓、標(biāo)簽盒安裝尺寸與西德克朗斯公司 30—8—6型貼標(biāo)機尺寸相一致

47、,與之具有互換性,擴展了該零配件的使用空間 。 (3)該鋁件標(biāo)掌為塑膠表面標(biāo)掌,該塑膠表面膠輯為全不銹鋼膠轆,延長了他們的使用壽命, 降低了膠水用量。 (4)膠刀分為上下兩段,用兩個汽缸分別控制,可分別調(diào)節(jié)上下膠水厚度,提高了貼標(biāo)合格率,同時可降低膠水用量。 (5)電氣控制方面采用了變頻調(diào)速,PLC 程序控制,提高了設(shè)備的可靠性與穩(wěn)定性,且操作箱可顯示生產(chǎn)能力和累計產(chǎn)量,便于控制與操作。 (6)采用整機不
