Description

一种免预热过胶机 技术领域
本发明涉及过胶机技术领域，尤其是涉及一种免预热过胶机。
背景技术
通常的，电子电器产品在待机状态下的耗电一般为其开机功率的10％左右。尽管近年来，欧委会公布第2005/32/EC号环保设计指令的实施规例议案，旨在降低所有家庭及办公室电气和电子设备在关机和待机状态下的能耗。议案中指出，欧盟市场生产和销售的电子和家用电器产品待机状态的最大功率消耗标准到2010年必须降到每小时1～2瓦特，2013年降至每小时0.5～1瓦特；同时要求电子电器产品须设计待机功率管理功能。尽管如此，如果电子电器产品长期待机，累积的耗电量也是相当大的。
另外，传统过胶机的加热方式采用发热丝加热，或者PTC加热，这两种加热方式靠介质传导热量到滚轴上面，热损失严重，所以导致比较长的时间才能达到过胶温度，而且发热丝以及PTC加热材料的热效率也较低，大大增加了过胶机的耗电量；另外一种用石英管加热的过胶机，靠传导和辐射两种方式加热，加快了预热时间，但预热时间仍然比较长，在1分钟到1.5分钟左右。
发明内容
本发明的目的是提供一种免预热过胶机，免除预热等待时间，降低能耗，绿色环保。
为了实现上述目的，本发明所采用的技术方案是：一种免预热过胶机，包括机身、设于机身前侧的过胶入口、设于机身后侧的过胶出口、设于机身内部的机 芯组件以及控制装置，过胶入口处设置有进胶检测装置以及进胶辊组，进胶辊组与机芯组件之间设有进胶通道，机芯组件的内部设置有压胶辊组以及靠近设于压胶辊组的发热组件，进胶辊组传动连接有进给驱动装置；其中，进胶检测装置、进给驱动装置、进胶辊组以及发热组件分别电连接控制装置，过胶物通过过胶入口时触发进胶检测装置，进胶检测装置发出进胶信号至控制装置，控制装置发送进给信号至进给驱动装置，并同时发送预热信号至发热组件；接收到进给信号的进给驱动装置带动进胶辊组进给配合，过胶物在进胶辊组的进给作用下通过进胶通道并进入至压胶辊组，其进给时间为t1；接收到预热信号后的发热组件运行发热，使压胶辊组升温至过胶温度，其升温时间为t2；进给时间t1和升温时间t2满足条件：t1大于或等于t2。
本发明和现有技术相比所具有的优点是：本发明提供了一种免预热过胶机，通过在进胶口设置电连接控制装置的进胶检测装置，实现仅在感应到入口插入胶膜后才启动加热，并且在无新胶插入的情况下经过设定时间后自动切断加热组件的电源停止加热，仅保留部分极低功耗之电路处于待机状态，待机状态加热组件不通电不补温，在连续过胶的过程中不需要连续或间歇加热胶辊，节能环保；在进胶口的进胶辊组和压胶辊组之间设置进胶通道，使过胶物在推送至压胶辊组之间形成进胶时间，以争取压胶辊组的升温时间，达到免预热的技术效果；进胶辊组和压胶辊组之间具有线速度差，使得过胶物在过胶过程中保持绷紧状态，避免起皱等不良因素，提高过胶质量。

具体实施方式
一种免预热过胶机，如图1至图8所示，包括机身1、设于机身1前侧的过胶入口10、设于机身1后侧的过胶出口15、设于机身1内部的机芯组件以及控制装置，其特征在于：过胶入口10处设置有进胶检测装置以及进胶辊组，进胶辊组与机芯组件之间设有进胶通道30，机芯组件的内部设置有压胶辊组以及靠近设于压胶辊组的发热组件，进胶辊组传动连接有进给驱动装置；其中，进胶检测装置、进给驱动装置、进胶辊组以及发热组件分别电连接控制装置，过胶物通过过胶入口10时触发进胶检测装置，进胶检测装置发出进胶信号至控制装置，控制装置发送进给信号至进给驱动装置，并同时发送预热信号至发热组件；接收到进给信号的进给驱动装置带动进胶辊组进给配合，过胶物在进胶辊组的进给作用下通过进胶通道30并进入至压胶辊组，其进给时间为t1；接收到预热信号后的发热组件运行发热，使压胶辊组升温至过胶温度，其升温时间为t2；进给时间t1和升温时间t2满足条件：t1大于或等于t2。通过在过胶入口10设置电连接控制装置的进胶检测装置，以及在过胶出口15设置电连接控制装置的出胶检测装置，实现仅在感应到入口插入胶膜后才启动加热，在胶膜通过出口后切断加热组件的电源停止加热，仅保留部分极低功耗之电路处于待机状态，待机状态加热组件不 通电不补温，在连续过胶的过程中不需要连续或间歇加热胶辊，节能环保；在进胶口的进胶辊组和压胶辊组之间设置进胶通道30，使过胶物在推送至压胶辊组之间形成进胶时间，以争取压胶辊组的升温时间，达到免预热的技术效果。
过胶出口(15)处设置有出胶检测装置，出胶检测装置电连接控制装置，过胶物通过过胶出口(15)时触发出胶检测装置，出胶检测装置发送出胶信号至控制装置，控制装置发送停止信号至发热组件，以控制发热组件停止加热。
还包括电源装置，控制装置、进给驱动装置以及机芯组件分别连接电源装置；进胶检测装置设有用作控制过胶机自动关机的计时模块，计时模块通讯连接控制装置，计时模块预设有关闭时间预设值；当过胶物脱离触发进胶检测装置时计时模块开始计时，控制装置实时或定时读取计时模块的计时时间，在读取所得的计时时间大于或等于关闭时间预设值时，控制装置控制电源装置断开供电，以实现自动关机。通过设置计时模块记录在过胶物完全通过过胶入口10后的累计时间，以实现在设定时间累计时间后控制过胶机自动关机，避免整机继续空转，节能省电。
机身1的包括上机壳11和下机壳12，上机壳11的前侧内部成型有多个间隔设置上鳍片111，下机壳12的前侧内部成型有多个间隔设置下鳍片121，各上鳍片111和下鳍片121对齐或错开设置，各上鳍片111的底边水平对齐并形成进胶通道30的顶面；各下鳍片121的顶边水平对齐并形成进胶通道30的底面，在上机壳11和下机壳12装配时各上鳍片111和下鳍片121恰好形成设定高度的进胶通道30，进胶通道30的高度为0.5cm-1cm，进胶通道30的高度根据不同规格大小的过胶机而设定，不作限定。
进胶检测装置可以采用非接触式或接触式的检测机构，优选地，过胶入口10 出设有进胶托台2，进胶托台2的内部旋转安装有一进胶触发轴杆21，进胶触发轴杆21与进胶托台2之间连接有扭转弹簧；进胶触发轴杆21沿其轴心方向间隔设置多轴向对齐的触发鳍片22，各触发鳍片22分别活动阻挡于过胶入口10；进胶触发轴杆21的端部设置有微动开关23，微动开关23与控制装置电连接，在过胶物通过过胶入口10时进胶触发轴杆21触发微动开关23。这种接触式的进胶检测结构，成本更低，更易于推广。
压胶辊组的线速度大于进胶辊组的线速度，并且压胶辊组与过胶物之间的静摩擦力大于进胶辊组与过胶物之间的静摩擦力，过胶物在进胶辊组的进给作用下通过进胶通道30并进入至压胶辊组时，进胶辊组和压胶辊组分别同时与过胶物的前后两侧辊压配合，并且进胶辊组与过胶物之间作滑动摩擦配合、压胶辊组与过胶物之间作静摩擦配合；进胶辊组包括相互平行设置的主动进胶辊31和被动进胶辊32，主动进胶辊31传动连接进给驱动装置。
主动进胶辊31的辊面和被动进胶辊32分别包括一金属辊，金属辊的辊面光滑设置，这两个金属辊之间设有过胶打滑结构，过胶打滑结构包括辊面间隙结构和弹性辊组结构的任意一种；其中，辊面间隙结构，主动进胶辊31的辊面和被动进胶辊32的辊面之间形成进胶间隙，进胶间隙小于过胶物的厚度；弹性辊组结构，主动进胶辊31的辊面和被动进胶辊32的辊面相互活动抵顶配合，被动进胶辊32的两端分别连接有弹性结构，被动进胶辊32作上下方向的弹性浮动配合。这种过胶打滑结构能够保证过胶物与进胶辊组之间保持足够的静摩擦力的同时避免压辊组件与过胶物之间打滑，保证过胶物顺利热封，避免热压过度，使过胶物热封失败。
机芯组件设有机芯壳，机芯壳包括上下对称设置的上芯壳41和下芯壳42， 上芯壳41和下芯壳42之间间隔形成热封进口401和热封出口402，热封进口401位于机芯壳的前侧并连通进胶通道30；热封出口402位于机芯壳的后侧并连通过胶出口15，压胶辊组位于机芯壳的内部，压胶辊组包括上下并拢设置的相同规格的上压辊44和下压辊43，上压辊44的前后两侧分别设置有一发热管45，这两个发热管45与上压辊44之间留有热辐射间隙；下压辊43的前后两侧分别设置有另一发热管45，这两个发热管45与下压辊43之间留有另一热辐射间隙。分别设于上压辊44和下压辊43前后两侧的发热管，使上压辊44和下压辊43能够更快地达到过胶温度，缩短升温时间，使上压辊44和下压辊43能够在过胶物的前侧边完全通过进胶通道30时达到过胶温度，符合该免预热过胶机的升温要求。
热封出口402与过胶出口15之间设有过胶整平机构5，过胶整平机构5包括整平底板52以及整平压板51，整平压板51弹性安装于整平底板52的顶部，整平压板51呈倾斜设置，整平底板52与整平压板51之间形成由内向外逐渐并拢的整平通道50，整平通道50的内侧开口连通热封出口402、外侧开口连通过胶出口15；其中，整平压板51的底部设有补温加热装置53，补温加热装置53电连接控制装置。在胶辊与出口之间的后通道安装过胶整平机构5，整平底板52对胶膜的加热温度小于胶辊的加热温度，起保温作用，减缓胶膜降温速度，避免过胶后的胶膜因急剧降温而产生皱褶或波浪纹，提升过胶质量。
过胶出口15处设有出胶辊组，出胶辊组传动连接进给驱动装置，出胶辊组的线速度大于压胶辊组的线速度，并且出胶辊组与过胶物之间的静摩擦力小于压胶辊组与过胶物之间的静摩擦力，过胶物在压胶辊组的进给作用下通过整平通道50并进入至出胶辊组时，出胶辊组和压胶辊组分别同时与过胶物的前后两侧辊压配合，并且出胶辊组与过胶物之间作滑动摩擦配合、压胶辊组与过胶物之间作静 摩擦配合。通过设置在出口处的出胶辊组吸卷胶膜，拉紧压胶辊组与出胶辊组之间的胶膜，避免过胶后的胶膜产生皱褶或波浪纹，进一步提升过胶质量。
过胶出口15处还设置有出胶托台6，出胶托台6活动连接于机身1，并且出胶托台6与机身1之间设有限位结构，出胶托台6的台面与过胶出口15平齐设置，对出胶温度较高较软的过胶物留有平面支撑作用，避免过胶物在重力作用下折弯定型，影响过胶质量。出胶托台6可以为分体式设计或旋转折叠式设计，具有利于收纳的优点。
上芯壳41的中间位置设置有温度检测装置46，温度检测装置46电连接控制装置，温度检测装置46包括红外温度传感单元或热电偶461。优选地，上芯壳41的中间位置开设有通孔410，温度检测装置46固定于通孔410处，并且选用的热电偶461通过通孔410伸入至机芯壳的内部并与上压辊44接触，以实时监测上压辊44的辊面温度，结构简单可靠，成本低，使用寿命长。
机身1内部的左右两侧分别设有第一侧板13和第二侧板14，第一侧板13和第二侧板14之间间隔形成机芯装配空间，主动进胶辊31、被动进胶辊32、上芯壳41、下芯壳42、上压辊44、下压辊43以及各发热管45分别插设于安装于机芯装配空间；第一侧板13的外侧设有传动齿轮组结构，传动齿轮组结构包括沿动力传递方向依次啮合连接的主驱动齿轮81、压辊齿轮组、变速齿轮组以及进胶辊齿轮87，主驱动齿轮81传动连接进给驱动装置；其中，压辊齿轮组包括相同规格的相互啮合的主压辊齿轮82和副压辊齿轮83，主压辊齿轮82和副压辊齿轮83分别同轴安装于上压辊44和下压辊43，主驱动齿轮81与主压辊齿轮82啮合连接；进胶辊齿轮87同轴安装于主动进胶辊31；主压辊齿轮82与进胶辊齿轮87之间形成传动比i；上压辊44和下压辊43的半径均为R1，主动进胶辊31 的半径为R2，并符合条件：R1×i＞R2。
