Description

一种应用于粉末喷涂线的立式圆形喷房
技术领域
本发明涉及粉末喷涂领域，特别是用于粉末喷涂线的喷房。
背景技术
目前，市面上存在并使用的立式粉末喷涂线喷房，主要有两种，分别是V型立式粉末喷房和U型立式粉末喷房，参照图1，V型立式粉末喷房结构相对简单，采用透明塑料薄膜制作两块相同的夹板一1’，两块夹板一1’围合形成一个V形的开口槽，开口槽的后部设置有一条抽风缝，抽风缝连接有抽风管一10’，开口槽的开口端处设置有一条沿着其开口形状延伸的悬挂链2’，悬挂链2’将工件依次运送到开口槽的开口端处进行粉末喷涂，然后再将其送走，在对工件进行粉末喷涂时，空气中会残留许多粉尘，因此需要开动抽风机并通过抽风管一10’将含有粉尘的空气抽走并分离过滤，由于V型立式粉末喷房的开口面积很大，需要采用功率很大的抽风机才能将含有粉尘的空气抽取干净，避免粉尘扩散，能耗大，另外要喷涂不同颜色的粉末时，V型立式粉末喷房需要更换制作夹板一1’的塑料薄膜，因此更换速度稍慢，影响了生产效率；
参照图2，U型立式粉末喷房，同样采用透明塑料薄膜制作三块挡板二1’’， 三块挡板二1’’围合形成一个U形开口槽，相邻的两块挡板二1’’之间留有一条抽风缝，所述抽风缝处连接有抽风管二10’’， U形开口槽的开口端处设置有一条沿着其开口形状延伸的悬挂链2’’，悬挂链2’’将工件依次运送到U形开口槽的开口端处进行粉末喷涂，然后再将其送走，在对工件进行粉末喷涂时，空气中会生产许多粉尘，因此需要开动抽风机并通过抽风管二10’’将含有粉尘的空气抽走并分离过滤，由于U型立式粉末喷房的开口面积比较大，仍需要采用功率比较大的抽风机才能将含有粉尘的空气抽取干净，避免粉尘扩散，能耗相对较大，另外要喷涂不同颜色的粉末时，U型立式粉末喷房需要更换制作挡板二1’’的塑料薄膜，虽然采用了机械皮带转动装置更换塑料薄膜，更换速度稍快，但是易损件多，增加了生产成本。
因此以上的两种喷房仍不能很好地满足企业的生产需要。
发明内容
为了解决上述问题，本发明的目的在于提供一种结构简单，同时可以缩小喷房的开口面积，降低抽风机功率，减少能耗的喷房。
本发明为解决其技术问题而采用的技术方案是：
一种应用于粉末喷涂线的立式圆形喷房，包括立式的喷房主体，所述喷房主体主要由分别位于前后侧的前侧板和后侧板围合而成，前、后侧板的中部均向外拱起形成圆弧状，该喷房主体的左右两侧分别设置有用于供工件进出的进料口和出料口，所述后侧板中部向外拱起的位置处开设有与外界抽风管道相连接的抽风口。
作为上述技术方案的改进，所述前侧板中部向外拱起的位置处开设有供喷枪装置上下移动的开口。
作为上述技术方案的进一步改进，所述喷房主体左右两侧的进料口和出料口上部分别设置有清理门，该清理门连接有驱动其转动的驱动装置，驱动装置固定安装在喷房主体靠近该清理门的位置上。
进一步，所述驱动装置为气缸或液压缸。
再进一步，所述喷房主体的底部设置有一倾斜面，该倾斜面的一侧设置有能够与其围合形成V型承接槽的自动翻板，自动翻板连接有驱动其转动的气缸。
进一步，所述喷房主体的底部设置有多个用于清理积聚在喷房主体底部的粉尘的环形气刀及横气刀。
再进一步，所述喷房主体的内部还设置有用于清理其内壁上积聚的粉尘的旋转式自动清理气枪，该旋转式自动清理气枪包括底座，该底座的中部设置有一个中空的旋转传动轴，旋转传动轴的上端部固定连接有气管，该气管的两端分别安装有喷头，所述旋转传动轴的下端还设置有用于与外界进气管道相连接的旋转接头，同时旋转传动轴的一侧还设置有驱动其转动的电机，所述电机固定安装在底座上。
进一步，所述喷房主体的外侧还设置有一台升降机，该升降机上设置有一能够伸入所述喷房主体内部且能够上下移动的连接杆，所述旋转式自动清理气枪固定安装在该连接杆上。
本发明的有益效果是：由于本发明的立式圆形喷房采用前侧板和后侧板围合形成一个相对封闭的空间，前侧板和后侧板的中部向外拱起形成圆弧状，因此喷房的内部有足够的空间以对工件进行粉末喷涂，因此，喷房左右两侧的进料口和出料口可以做得比较小，减少了喷房的开口面积，因此采用功率比较小的抽风机即可满足喷房对抽风的需求，使得喷涂粉末的过程中，残留在空气中的粉末不会向外扩散，保护生产环境，同时减少了喷房30%以上的能耗，大大地降低了企业的生产成本；另外喷房底部设置有自动翻板及多个清理粉末的气刀，防止底部积粉，使粉末更容易回收；另外喷房的前、后侧板采用塑料板制成，粘附粉末少，绝缘性能好，更换不同颜色的粉末时，无需更换薄膜或产生损耗件，只需要采用气枪清理残留粉末即可，大大提高了喷房的换色速度，换色时间比传统喷房节约了1/2左右，极大地提高了生产效率。

具体实施方式
参照图3至图 8，一种应用于粉末喷涂线的立式圆形喷房，包括立式的喷房主体1，所述喷房主体1主要由分别位于前后侧的前侧板11和后侧板12围合而成，这里所述前侧板11和后侧板12优先采用塑料板制造，因此前侧板11和后侧板12不导电，既降低了生产成本，又便于喷涂粉末，进一步，为了使得前侧板11和后侧板12具有足够的强度，采用三明治结构的PP板制造前侧板11和后侧板12，当然前侧板11和后侧板12采用单层的塑料板或者其他绝缘的材料制造也是可以的；前、后侧板11、12的中部均向外拱起形成圆弧状，因此使得喷房主体1外形看起来像圆柱形，同时喷房主体1的内部又可以具有足够的空间以进行粉末喷涂；该喷房主体1的左右两侧分别设置有用于供工件进出的进料口13和出料口14，因此用于输送工件的悬挂链4可以从进料口13处进入到喷房主体1的内部，沿着后侧板12的内壁向前移动，最后再从出料口14处离开喷房主体1，由于进、出料口13、14只需要供悬挂链4带动工件进出喷房主体1，因此进、出料口13、14的开口可以做得比较小，从而减少喷房主体1的开口面积；同时，为了避免喷涂粉末时，残留在空气中的粉末会从进、出料口13、14处逸出并扩散到外界空气中和污染环境，因此所述后侧板12中部向外拱起的位置处开设有与外界抽风管道相连接的抽风口120，通过外置的抽风设置将喷房内的空气抽取回收，进行分离和过滤，有效避免了粉尘污染，上述围合形成喷房主体1的前侧板11和后侧板12可以采用一体成型的结构，也可以采用分体结构，为了便于对喷房主体内部的零件进行组装和维修，在本发明中，所述前侧板11和后侧板12优先采用分体设置的结构。
由于本发明的立式圆形喷房采用前侧板11和后侧板12围合形成一个相对封闭的空间，前侧板11和后侧板12的中部向外拱起形成圆弧状，因此喷房的内部有足够的空间以对工件进行粉末喷涂，因此，喷房左右两侧的进料口13和出料口14可以做得比较小，减少了喷房的开口面积，因此采用功率比较小的抽风机即可满足喷房对抽风的需求，使得喷涂粉末的过程中，残留在空气中的粉末不会向外扩散，保护生产环境，同时减少了喷房30%以上的能耗，大大地降低了企业的生产成本。
进一步，为了便于采用外部的升降设备带动用于喷涂粉末的喷枪装置2上下移动，所述前侧板11中部向外拱起的位置处开设有供喷枪装置2上下移动的开口110，因此外部升降设备的升降连杆可以从开口110处伸入喷房主体1内部并承载喷枪装置2，因此升降连杆在开口110处上下移动，从而带动喷枪装置2上下移动，若将升降设备安装在喷房主体1的内部时，前侧板11上不开设所述的开口110也可以，但是那样不便于对升降设备进行维护，以及会占用较多的喷房主体1内部空间。
再进一步，为了减少喷房主体1的开口面积，所述喷房主体1左右两侧的进料口13和出料口14上部分别设置有清理门15，清理门15关闭时，可以进一步减少喷房主体的开口面积，但是由于立式喷房的高度相对较高，因此安装在进料口13和出料口14上部的清理门15处于较高的位置，人手难以开启或关闭，因而，该清理门15连接有驱动其转动的驱动装置150，驱动装置150固定安装在喷房主体1靠近该清理门15的位置上，优选地，所述驱动装置150为气缸或液压缸，那当然采用电机和丝杆相配合的结构代替也是可以的，不过那样会稍微地增加生产成本。
进一步，为了便于清理喷房内部积聚的粉末，所述喷房主体1的底部设置有一倾斜面，该倾斜面的一侧设置有能够与其围合形成V型承接槽的自动翻板16，自动翻板16连接有驱动其转动的气缸，通过上述的自动翻板16与倾斜面形成的V型承接槽，能够使得粉末更容易地进入抽风道中并被回收。
再进一步，为了可以更好地清理积聚在喷房主体1底部的粉末，所述喷房主体1的底部设置有多个用于清理积聚在喷房主体1底部的粉尘的环形气刀及横气刀，当需要清理积聚的粉末时，通过启动上述多个环形气刀及横气刀将积聚的粉末吹落到抽风道中，然后再被抽走，从而实现清理喷房主体1内部粉末的目的。
进一步，当要喷涂不同颜色的粉末时，需要清理喷房主体1内部残留的粉末，以免发生混色的情况，若采用人工手动清理喷房主体1内部的粉末时，既需要耗费大量的时间，同时工作人员还打开喷方主体1并进入到其内部，容易发生意外情况，因而，所述喷房主体1的内部还设置有用于清理其内壁上积聚的粉尘的旋转式自动清理气枪17，该旋转式自动清理气枪17包括底座171，该底座171的中部设置有一个中空的旋转传动轴172，旋转传动轴172的上端部固定连接有气管173，该气管173的两端分别安装有喷头174，所述旋转传动轴172的下端还设置有用于与外界进气管道相连接的旋转接头175，同时旋转传动轴172的一侧还设置有驱动其转动的电机176，所述电机176固定安装在底座171上，上述电机176可以通过齿轮传动结构或者皮带传动结构与旋转传动轴172相连接，通过旋转接头175与外界进气管道相连接，外界的空气经过中空的旋转传动轴172进入到气管173中，最后在喷头174处喷出，由于安装有喷头174的气管173与旋转传动轴172固定连接，而旋转传动轴172则在电机176的作用下带动旋转，因此气管173则同时带动喷头174旋转，因此从喷头174处喷出的空气能够环向清理喷房主体1内部的粉末，既减少了喷房主体1内部清理粉末的时间，同时无需工作人员进入喷房主体1内部，防止意外事故的发生，保证安全。
再进一步，由于喷房主体1的自身高度较高，对于一些积聚在喷房主体1上部的粉末，人手难以对其进行清理，因此，所述喷房主体1的外侧还设置有一台升降机3，该升降机3上设置有一能够伸入所述喷房主体1内部且能够上下移动的连接杆30，所述旋转式自动清理气枪17固定安装在该连接杆30上，通过上述的升降机3，能够带动旋转式自动清理气枪17上下移动，从而清理位于喷房主体1内壁高处的粉末，以便于喷涂线更换不同颜色的粉末，保证不会发生混色的情况,优选地，在本实施例中，所述喷枪装置2也固定安装在连接杆30上。
以上所述仅为本发明的优先实施方式，只要以基本相同手段实现本发明目的的技术方案都属于本发明的保护范围之内。
