具体实施方式
本部分将详细描述本发明的具体实施例，本发明之较佳实施例在附图中示出，附图的作用在于用图形补充说明书文字部分的描述，使人能够直观地、形象地理解本发明的每个技术特征和整体技术方案，但其不能理解为对本发明保护范围的限制。
参照图1至图3，本发明实施例提供一种口罩耳带输送组件，包括用于将耳带10输送至预定位置的送料模组100和送料组件200，送料模组100包括间隔 设置且具有预定间隙的第一送料模块110和第二送料模块120，口罩本体20沿着预定方向不断连续输送，口罩本体20的输送方向由第一送料模块110向第二送料模块120输送。
在本实施例的描述中，上、下的方位朝向如图1标注所示，为了便于直观理解送料模组的结构形式，第一送料模块110和第二送料模块120的底面是朝上，在实际口罩生产加工过程中，第一送料模块110和第二送料模块120的底面是朝下的，口罩本体20大约贴着第一送料模块110和第二送料模块120的底面进行移动输送。
在第一送料模块110底面设置第一限位槽111，在第二送料模块120的底面设置第二限位槽121，第一限位槽111和第二限位槽121均为凹槽或嵌槽结构，即在第一送料模块110和第二送料模块120的底面挖槽形成底面敞口，图1示意中底面敞口的方向朝上，第一限位槽111和第二限位槽121在水平方向或者同一个平面内的路径均呈半环形，两者大致呈对称形式分布，第一限位槽111和第二限位槽121组合形成的路径在水平方向或者同一个平面内呈环形或者跑道形，第一限位槽111的首尾两端分别构成第一耳带入口1111和第一耳带出口1112，第二限位槽121的首尾两端分别构成第二耳带入口1211和第二耳带出口1212，使得耳带10能够顺利经过第一限位槽111和第二限位槽121。
其中，第一耳带入口1111与第二耳带出口1212相对，第一耳带出口1112与第二耳带入口1211相对，耳带10从第一限位槽111的第一耳带入口1111进入，经过第一限位槽111的第一耳带出口1112送出后，又从第二限位槽121的第二耳带入口1211进入，再经第二限位槽121的第二耳带出口1212送出，即耳带10能够在第一限位槽111和第二限位槽121内呈逆时针方向不断地循环移动输送。为了便于耳带10能够顺利通过第二耳带入口1211进入第二限位槽121和通过第一耳带入口1111进入第一限位槽111，第一耳带入口1111和第二耳带入口1211均设置倒角结构。
在本发明实施例中，在第二送料模块120内部设置与第二限位槽121连通的 气流通道130，气流通道130被设置为通入气流，气流经过气流通道130进入第一限位槽111和第二限位槽121大致沿逆时针方向流动，在气流的作用下，耳带10随着气流被带动，进而在第一限位槽111和第二限位槽121呈逆时针方向移动输送。
可以理解的是，气流的强度的可以根据实际情况灵活选择，只要能够带动或吹动耳带10进行移动输送即可。
在另外一些实施例中，还可以另外设置抽吸组件(未画出)，通过抽吸组件用于对限位槽内的气体进行吸气，进而改变限位槽内的气流强度，使得耳带在限位槽内移动更为顺畅，例如，在耳带入口进行吹气，在耳带出口进行吸气，两者配合对耳带进行移动输送。
如图8所示，在其中一些实施例中，在第二送料模块120内部设置与第二限位槽121连通的抽气通道150，抽气通道150与抽吸组件相连，以对抽气通道150进行抽气，抽气通道150与第二耳带入口1211相通，在第二耳带入口1211处形成一定吸力，从而使得耳带10在气流的作用下，能够更顺利、更顺畅地通过第二耳带入口1211进入第二限位槽121内。
在本发明实施例中，在第二送料模块120内设置与第二限位槽121连通入料通道140，入料通道140用于供耳带10进入送料模组100内，气流通道130与入料通道140相交，气流经过气流通道130进入，带动位于入料通道140内的耳带10移动进入第一限位槽111、第二限位槽121，其中，在气流通道130与入料通道140相交处，两者之间的中心轴线之间形成锐角，即在相交处气流在气流通道130内的流动方向与耳带10在入料通道140内的输送方向构成锐角，有利于气流带动耳带10移动输送。
在本发明实施例中，耳带10的移动输送的位置通过送料组件200进行控制，具体地，送料组件200包括两个抵顶接触的滚轮210，耳带10从两个滚轮210之间穿过，两个滚轮210夹住耳带10，此时耳带10被锁定，无法移动输送，当两个滚轮210同步反向旋转时，通过滚动抵压耳带使得耳带能够在气流的作用下 进行移动输送，当两个滚轮210停止旋转时，耳带10的移动输送暂停，如此，在两个滚轮210滚动控制耳带和气流带动控制耳带的双重作用下，使得耳带10的端部能够刚好经第二限位槽121的第二耳带出口1212露出部分，进而使得耳带10在第一限位槽111、第二限位槽121内呈环形或跑道形排布，以便于进行后续的焊接和裁切工序。
通过送料模组100和送料组件200两者的协同配合，使得耳带10在第一限位槽111、第二限位槽121内移动输送并呈环形或跑道形排布，以便于后续能够一次性焊接两个口罩耳带，有效地提高生产效率。
其中，气流是连续不断地经气流通道130吹入，能够通过气流带动耳带10移动输送，而两个滚轮210只有在同步反向旋转时的情况下，耳带才会随着气流移动输送，只要控制两个滚轮210的旋转动作的频率和时间即可准确控制耳带10输送位置，即通过控制两个滚轮210的旋转动作就能够选择性地锁定耳带。
可以理解的是，也可以是两个滚轮210同步反向旋转预先输送预定长度的耳带10，然后两个滚轮210停止旋转，锁定耳带10，再向气流通道130通入气流，通过气流带动耳带10进入第一限位槽111、第二限位槽121内移动输送并呈环形或跑道形排布，即气流还可以被设置为间歇性通气。
当然地，在另外一些实施例中，送料组件200也可以只设置一个滚轮，滚轮被设置抵压在一个平面上，耳带10从滚轮与平面之间穿过，滚轮压住耳带10，此时耳带10被锁定，无法移动输送，当滚轮旋转时，通过滚动抵压耳带使得耳带能够在气流的作用下进行移动输送，当滚轮停止旋转时，耳带10的移动输送暂停。
在另外一些实施例中，送料组件200还可以设置为夹持机构，能够夹住或松开耳带10，即能够选择性锁定耳带，同样地，只有在夹持机构松开耳带10的情况下，耳带才会随着气流移动输送。
参照图4，在其中一些实施例中，可以在第一送料模块110和第二送料模块120上分别设有独立的气流通道130，通过各自的气流通道130分别引导气流进 入第一限位槽111、第二限位槽121，从而带动耳带10移动输送。
可以理解的是，气流通道130的数量还可以设置为多个，本领域技术人员可以根据实际情况灵活选择，只要气流通道130被构造成有利于耳带10在气流带动下移动输送即可，例如气流通道130与第一限位槽111和/或第二限位槽121之间相切。
参照图5，在其中一些实施例中，可以在第一送料模块110和第二送料模块120上分别设置独立的入料通道140，相应地，设置两个送料组件200用于分别提供两条耳带10各自对应输送进入第一限位槽111、第二限位槽121内，每条耳带10的滚动控制和气流带动控制与前述方式相同，在此不在赘述，每条耳带10进行移动输送对应在第一限位槽111、第二限位槽121内环绕呈半环形，两条耳带10相互组合即可构成环形或跑道形，从而便于后续能够一次性焊接两个口罩耳带，有效地提高生产效率。
在其中的一些实施例中，气流通道130与入料通道140可以二合为一，即只设置气流通道130，耳带10从气流通道130进入，气流直接带动位于气流通道130内的耳带10进入第一限位槽111、第二限位槽121。
参照图6和图7，气流通道130可与入料通道140二合为一，即耳带10沿气流通道130进入第一限位槽111、第二限位槽121，同时气流从气流通道130通入第一限位槽111、第二限位槽121，气流通道130可连接外部一软管131作为进气管，在软管131的端部设置一进气头132，进气头132的内部具有环形槽1321，环形槽1321靠近软管131的一端开口，进气头132的侧壁设有连通环形槽1321的通孔作为进气孔1322。耳带10穿过软管131进入气流通道130，从进气孔1322通入气流，气流携带耳带10同时进入软管内，进而使得耳带10从气流通道130直接进入第一限位槽111、第二限位槽121内。
当然，可以理解的是，送料模组100可以仅仅设置单个限位槽与单个的送料组件200相互配合，将耳带10引导输送在限位槽内呈半环形排布，以将耳带焊接在口罩本体的其中一侧，如此，即一次性只能焊接一个口罩耳带。
参照图9，本发明实施例提供一种口罩耳带焊接装置，包括上述的口罩耳带输送组件和焊接组件300，焊接组件300包括上、下分布的第一焊接模头、第二焊接模头，第一焊接模头与第二焊接模头相互配合将耳带焊接在口罩上。
在本发明实施例中，焊接组件300设置在第一送料模块110与第二送料模块120之间的预定间隙处，口罩耳带输送组件将耳带连续不断地呈环形或跑道形移动输送至预定位置，焊接组件300工作能够一次性焊接两个口罩耳带，有效地提高生产效率。
在另外一些实施例中，口罩耳带焊接装置还包括裁切组件，裁切组件集成在焊接组件上，焊接组件300对耳带进行焊接的同时，对耳带进行裁切，将口罩耳带切断工序和口罩耳带焊接工序二合为一，最大限度地简化机械结构，减少机械零部件，使得机械结构故障率更低，结构简单降低成本。
参照图10，本发明实施例提供一种口罩制造设备，包括上述口罩耳带焊接装置，通过上述口罩耳带焊接装置对口罩耳带进行焊接固定，摒弃了传统“一拖二”口罩机的口罩耳带焊接机构，减少机构数量，简化结构，有效地提高口罩的生产加工效率。
