本申请要求享有于2021年09月28日提交的名称为“一种吸枪及吸料装置”的中国专利申请202122391754.2的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本申请涉及吸料设备的技术领域，具体涉及一种吸枪及吸料装置。
背景技术
在产品的生产制造过程中，需要将加工所需的物料运送到指定的位置进行加工和处理。通常情况下，工作人员将物料盛放在物料袋或箱子等载体中，以方便运输前后的装卸。当盛放物料的载体到达指定的位置后，再将其中盛放的物料取出，并将其转移到加工位置进行下一步的加工。
物料有固体、液体等存在形式，不同存在形式的物料所适用的盛放方式不同，卸料时采用的取出方式也不同。例如，液体可盛放在塑料容器、玻璃容器或金属容器中，若该液体具有腐蚀性时，还需要考虑容器的耐腐蚀性，液体取出时一般通过管道流出。再以固体为例，若该固体为体积较大的块状，可将其盛放在网状物料袋或网状箱子中，但若该固体为体积较小的固体颗粒，则需要将其盛放在结构密实的物料袋或箱子中，以防止固体颗粒泄露，固体取出时一般通过夹取或倾倒的方式。
但是，对于体积较小的固体颗粒，在卸料时，极容易在物料袋的褶皱或者箱子的缝隙中残留，这不仅导致物料的浪费和成本的增加，而且，当残留在物料袋或箱子中的物料进入环境中时，还可能对环境造成污染、 对人体健康造成危害。因此，无论是从环境角度还是健康角度，亦或是节约资源角度，都需要尽快解决目前在卸料结束时物料在物料袋或箱子内的物料残留的问题。
发明内容
鉴于上述问题，本申请实施例提供了一种吸枪及吸料装置，可以吸收多个位置和角度的物料，有效减少在卸料结束时物料在物料袋或箱子内的残留。
根据本申请实施例的一个方面，提供了一种吸枪，吸枪包括：
枪头，枪头上设有吸料口，吸料口用于吸收位于待吸收区的物料；
吹气结构，包括吹气管和设于吹气管的管壁上的吹气孔，吹气孔用于吹出气流，以将物料吹至吸料口。
通过采用上述方案，将吸枪置于物料的待吸收区，吸枪将距离吸料口较近位置的物料吸走，在吸枪吸料的过程中，由吹气结构将物料吹至吸料口，可以将距离吸料口较远或所处角度不方便吸料口吸入的物料送至吸料口容易吸入的区域，方便吸料口吸收物料，从而可以吸收更大范围的物料，以减少在卸料结束后物料在物料袋或箱子内的残留。
在一些实施例中，吹气管连接于枪头上。
通过采用上述方案，将吹气管和枪头的相对位置固定，可以使吹气管自动跟随枪头的移动而移动，省去在枪头吸料时调节吹气管位置的时间，从而更快的进行吸料，提高吸料效率。
在一些实施例中，吹气管的管壁环绕枪头设置，且吹气孔位于吹气管的靠近吸料口一侧。
通过采用上述方案，使吹气孔吹出的气流可以更靠近吸料口，由于气流经过区域的气压会升高，当气流经过区域和吸料口之间的距离较近 时，由于两个位置之间存在气压差，因此物料会自动从气流经过区域移动到吸料口，以便于被吸枪从吸料口吸入。该设置使得吹气孔可以更高效的将物料吹至吸料口方向，使吹气效果更好，从而将位置较远或不方便吸到的物料吸入吸枪，减少在卸料结束后物料的残留。
在一些实施例中，枪头具有轴线，吸料口设有多个，且多个吸料口围绕枪头的轴线设置，从多个位置吸收物料。
通过采用上述方案，可以吸收位于枪头四周的各个位置的物料，不同的吸料口从不同的角度吸收物料可以使吸枪吸收更多位置的物料，以减少卸料结束后物料的残留，并且，多个吸料口同时吸收还可以增加单位时间内的物料流量，提高吸料效率。
在一些实施例中，吸料口固定有过滤网，过滤网上设有网孔，用于过滤物料。
通过采用上述方案，可以进一步地对吸收的物料进行过滤，以防止不符合要求的物料或其他异物进入吸料口，保证吸收进来的物料的纯度。
在一些实施例中，吹气管与枪头同轴设置，吹气孔设有多个，多个吹气孔围绕枪头的轴线间隔设置，以便于从多个位置将物料吹至吸料口。
通过采用上述方案，可以将枪头四周的多个位置的物料分别通过不同的吹气孔吹至吸料口，从而保证吸料口可以吸收更多位于枪头四周的物料，减少物料残留。
在一些实施例中，吹气孔的轴线与枪头的轴线之间具有第二夹角，第二夹角的角度值在60度到67.5度之间，以提高将物料吹至吸料口的准确度。
第二夹角太大会将物料吹至远离吸料口的位置，第二夹角太小则会很容易将吸料口附近的物料吹走，并且也很难将物料吹至吸料口。因此，将第二夹角的角度值设置在60度到67.5度之间，通过采用上述方案，可 以保证吹气孔吹气的方向能更好的将物料吹至吸料口，从而提高吸料效率。
在一些实施例中，枪头为中空结构的圆锥体或棱锥体，以利用枪头的尖部刺破盛装物料的物料袋。
通过采用上述方案，可以利用枪头直接刺破盛装物料的物料袋，省去了枪头吸收物料前的对物料袋的开口步骤。并且，利用枪头自身结构刺破物料袋，可以保证破开的口子的尺寸贴合枪头尺寸，既避免了根据枪头尺寸确定开口大小的步骤，又避免了在开口处泄露物料。
在一些实施例中，吸料口设于圆锥体或棱锥体的锥面上，且吸料口避开枪头的尖部，以增加尖部的锋利度。
通过采用上述方案，在刺破物料袋的过程中，可以缩小枪头的顶部与物料袋的接触面积，从而在同等力度的条件下使枪头具有更大的压强，以用较小的力度即可成功刺破物料袋。
在一些实施例中，圆锥体或棱锥体的顶角的角度值在30度至60度之间，以保持尖部的锋利度并增加吸料口组成的吸料区的面积。
通过采用上述方案，顶角太大会降低尖部的锋利度，顶角太小会导致吸料区的面积过小，造成吸料困难，因此选用此角度范围，同时考虑尖部的锋利度和吸料区的面积，做到两者的平衡，从而可以在使枪头的尖部的锋利度足以刺破物料袋的同时保证吸料区的面积，进而保证了吸料效率。
在一些实施例中，顶角的角度值为45度。
通过采用上述方案，可以使枪头上的吸料区的面积最大，以使得吸料效率最大，同时还保证了枪头的锋利度，以确保可以使用较小的力成功刺破物料袋。
根据本申请实施例的另一方面，提供了一种吸料装置，包括：
上述第一方面中任一项的吸枪；
伸缩装置，伸缩装置用于控制吸枪移动，以使得吸枪靠近物料；
补气装置，补气装置用于向吸枪的吹气管输入气体。
通过采用上述方案，伸缩装置可以控制吸枪在吸料开始时靠近物料，在吸料结束时远离物料，此外，还可以控制吸枪在吸料过程中随着吸料进程伸缩，以在合适的位置吸收物料，补气装置在吸料过程中向吹气管输入气体，以从吹气孔吹出气流，将物料吹至枪头的吸料口处，保证物料被吸料口吸收，减少物料残留的同时提高吸料效率。
在一些实施例中，吸料装置还包括：
气压控制装置，气压控制装置用于控制吸枪内部的气压低于吸枪外部的气压，以使吸枪外部的物料从吸料口吸入吸枪内部。
通过采用上述方案，可以增强吸枪内外的气压差，促使吸枪外部的物料被吸入吸枪内部，确保吸料效果，减少物料残留。
本申请实施例通过在吸枪的枪头设置吹气结构，通过吹气结构的吹气孔吹气，产生的气流附近的气压高于吸料口的气压，促使吸枪附近的物料向吸料口移动，从而扩大吸料口的可吸料范围，减少卸料结束后的物料残留。并且，吹气孔吹出的气流可以将距离吸料口较远或所处角度不方便吸料口吸入的物料送至吸料口容易吸入的区域，方便吸料口将其吸收，进一步减少在卸料结束后物料在物料袋或箱子内的残留。

本申请实施例所提到的物料，可以是在生产制造过程中用到的原材料，例如传统的电池生产制造所用的乙炔黑、锰粉、氧化锌粉、氯化铵，或锂离子动力电池生产制造所用的钴锂氧化物、锰酸锂、镍酸锂、磷酸铁锂、石墨等；也可以是普通装卸的物料，例如面粉、糖、盐等粉状或颗粒状材料。
在物料的使用过程中，往往需要将其从一个位置转移到另一个位置，例如从物料的制造地转移到生产车间，在这个过程中物料往往被盛放在物料袋中，因此不易发生遗漏。但在生产车间中，要想使用物料，就需要将物料从物料袋中取出。由于固体颗粒的体积较小，极容易掩藏在物料袋的褶皱或者箱子的缝隙中而不被发现，这就导致工作人员或卸料设备在卸料时将其忽略，从而使得卸料结束后物料袋中还残留着部分物料。物料残留在物料袋中，不仅造成资源的浪费，还增加了生产成本。除此之外，残留的物料一旦进入环境，比如车间，还会对其他工艺流程造成污染，影 响车间内工作人员的身体健康。
目前，多是通过运输设备将盛放物料的物料袋运输到生产车间的进料口上，然后将物料袋的底部划破，以使物料从底部被划破的开口中掉出，落至进料口中完成卸料过程。对于物料袋中不易掉落的部分物料，采用抖落的方式使其离开物料袋，以期落入进料口，但这种做法不适用于质量较小的物料。
对于质量较小的物料来说，自身的重力不足以保证其在没有外力作用的情况下竖直下落，反而在物料下落过程中容易飘散到各处，以至于不能完全落入进料口中。并且，质量较小的物料通常体积也不大，容易掩藏在物料袋的褶皱或箱子的缝隙中，通过有限次的抖动不能确保其一定从褶皱或缝隙中散出，部分物料藏匿于褶皱或缝隙中，一旦进入环境就会对环境造成污染、影响工作人员身体健康。
为了避免物料进入环境对环境和人体造成危害，需要在转移物料袋之前，解决卸料结束后的物料残留问题。基于此，本申请实施例提供了一种吸枪，通过本申请实施例提供的吸枪，可以减少在卸料结束时物料残留在物料袋或箱子内的情况。
本申请实施例提供的吸枪包括枪头和吹气结构，其中，枪头上设有吸料口1，吸料口1用于吸收位于待吸收区的物料。吹气结构包括吹气管2和设于吹气管2的管壁上的吹气孔3，吹气孔3用于吹出气流，以将物料吹至吸料口1。
图1是本申请实施例提供的一种吸枪在第一视角下的结构示意图，如图1所示，吸枪的枪头上设置有吸料口1，吸料口1可以有多个，以增加单位时间内被吸入的物料流量。多个吸料口1组成吸料区，用于吸收吸料口1及附近的物料。吹气结构的吹气孔3吹出气流，气流将吸枪附近的 物料吹至靠近吸料口1的位置，吸料口1再将物料从吸枪外部吸入吸枪内部，从而可以吸收更大范围的物料，减少卸料结束时物料残留在物料袋7或箱子内。
枪头是中空的结构，比如中空的半球形、中空的锥形等。枪头的侧壁上设有通孔，即吸料口1，吸料口1用于连通枪头的内腔与外界环境，吸料口1的形状可以是圆形、菱形等。物料从枪头的外部经吸料口1被吸入到内腔中，完成物料袋7中物料的卸料。
可以理解的是，本申请对枪头的形状和吸料口1的形状均不作限制。
吸料口1可以是一个或多个，当吸料口1为一个时，该吸料口1的大小直接影响着单位时间内吸收的物料的流量大小。当吸料口1为多个时，单位时间内吸枪吸收物料的流量大小为多个吸料口1流量的总数。由此可以看出，想要更快的完成卸料，吸料口1越多越好。
物料会从气压高的地方移动至气压低的地方，因此，吹气孔3可以在吸料口1的附近正对着吸料口1进行吹气，通过气流将物料带至吸料口1。吹气孔3也可以不朝向吸料口1吹气，以增大气流经过区域的气压，使得气流经过区域与吸料口1之间产生气压差，进而通过虹吸效应使物料向吸料口1移动。以上均可实现吹气孔3将物料吹至吸料口1。
本申请实施例提供的吸枪通过吹气结构将物料吹至吸料口1，可以将距离吸料口1较远或所处角度不方便吸料口1吸入的物料送至吸料口1容易吸入的区域，方便吸料口1吸收物料，从而可以吸收更大范围的物料，以避免在卸料结束后将物料残留在物料袋7内。
具体的，吹气管2上可以设置进气口4，气流从进气口4进入从吹气孔3吹出，进气口4为吹气孔3的气流来源提供入口。
在一些实施例中，吹气管2连接于枪头上。
示例性的，吹气管2可以粘接于枪头上，也可以通过一体成型制造工艺与枪头作为整体结构使用，还可以通过卡接、螺纹螺栓等方式与枪头固定在一起，本申请实施例对此不作限制。
吹气管2和枪头组成一个整体，吹气管2跟随枪头移动，也即，吹气管2跟随枪头的吸料口1移动，从而保证吹气管2吹出的气流始终可以将枪头附近的物料吹至吸料口1的位置，方便吸料口1吸料，减少物料在物料袋7内的残留。
本申请实施例提供的吸枪通过将吹气管2和枪头的相对位置固定，可以使吹气管2自动跟随枪头的移动而移动，省去在枪头吸料时调节吹气管2位置的时间，从而更快的进行吸料，提高吸料效率。并且，由于吹气管2和吸料口1的位置固定，可以确保吹气管2的吹气孔3在吸料过程中一直将物料吹至吸料口1，从而减少物料在物料袋7内的残留。
在一些实施例中，吹气管2的管壁环绕枪头设置，且吹气孔3位于吹气管2的靠近吸料口1一侧。
环绕是指吹气管2的管壁与枪头环绕同一个轴线。可以是吹气管2的管壁在枪头的外侧环绕，也可以是吹气管2的管壁在枪头的一端连接环绕。具体的，当吹气管2的管壁与枪头的一端形状和大小一致时，吹气管2的设有吹气孔3的一端可以粘接在枪头的远离吸料口1的一端。例如吹气管2为圆柱体且枪头远离吸料口1的一端也为圆形管道时，将吹气管2设有吹气孔3一端的管壁与枪头的圆形管道的管壁进行粘接，从而使吹气管2的管壁环绕枪头设置。当吹气管2的管壁与枪头的一端形状一致，且吹气管2的管壁大于枪头的一端尺寸时，吹气管2的管壁可以在枪头的外侧环绕固定。
吹气孔3吹出的气流以吹气孔3的出口为起点沿着气流方向逐渐减弱，气流在吹气孔3出口处的气压最大。当吹气孔3位于靠近吸料口1一侧时，可以保证吹气孔3吹出的气流的作用发挥到最大，更有力的将物料吹至吸料口1。
本申请实施例提供的吸枪通过将吹气孔3设于靠近吸料口的位置，使吹气孔3吹出的气流可以更靠近吸料口1，气流经过区域和吸料口1之间的气压差值更大，吹气孔3可以更高效的将物料吹至吸料口1方向，使吹气效果更好，从而将位置较远或不方便吸到的物料吸入吸枪，减少在卸料结束后的物料残留。
在一些实施例中，吸枪的枪头具有轴线，吸料口1设有多个，且多个吸料口1围绕枪头的轴线设置，以从多个位置吸收物料。
多个吸料口1可以增加吸收物料的速度，而围绕枪头的轴线设置多个吸料口1，可以保证每个吸料口1负责吸收枪头四周的不同位置的物料，从而保证全方位的吸收枪头附近的物料，避免在吸料过程中遗漏物料，从而避免卸料结束后物料残留在物料袋7内。
本申请实施例提供的吸枪通过吸收位于枪头四周的各个位置的物料，不同的吸料口1从不同的角度吸收物料可以使吸枪吸收更多位置的物料，以减少卸料完成后的物料残留，并且，多个吸料口1同时吸收还可以增加单位时间内物料流量，提高吸料效率。
在一些实施例中，吸料口1固定有过滤网，过滤网上设有网孔，用于过滤物料。
吸料口1的大小可以根据所吸收的物料的粒径大小来确定。一个吸料口1可以同时通过多个物料，也可以只能通过一个物料。当一个吸料口1一次只能通过一个物料时，可以在吸料口1外侧固定过滤网，此时过 滤网的网孔要小于吸料口1的大小，从而在较大的物料堵塞在吸料口1之前将其过滤。当一个吸料口1一次可以通过多个物料时，为了避免吸枪吸入除物料之外的杂物，可以在吸料口1上固定过滤网，对吸入的物料进行过滤。过滤网的网孔大小可以根据物料的大小来确定。过滤网和吸料口1互相配合，对吸入的物料进行二次过滤，以保证最后吸入的物料的纯度。
可以理解的是，本申请所称物料的纯度，并非指微观上物料自身的组成物的纯度，而是指宏观上物料不包含杂物的程度。
另外，在一个吸料口1一次可以通过多个物料的情况下，过滤网可以设置在吸料口1的内部，也可以设置在吸料口1的外部，本申请实施例对此不作限制。
本申请实施例提供的吸枪通过在吸料口1上固定过滤网，可以进一步地对吸收的物料进行过滤，以防止不符合要求的物料或其他异物进入吸料口1，保证吸收进来的物料的纯度。
在一些实施例中，吹气管2与枪头同轴设置，吹气孔3设有多个，多个吹气孔3围绕枪头的轴线间隔设置，以便于从多个位置将物料吹至吸料口1。
可选的，间隔设置可以是等间隔设置，也可以是不等间隔设置，可以是对称设置，也可以不对称，还可以以阵列方式设置。
其中，采用等间隔设置的吹气孔3所吹的气流有固定的区域，气流将枪头四周的物料按位置分担，互相之间的影响较小，避免了两道气流过近互相造成干扰或过远导致遗漏物料。
此外，等间隔设置、对称设置和阵列设置都更方便加工。
多个吹气孔3可以提高将物料吹至吸料口1的效率，而围绕枪头 轴线设置多个吹气孔3，可以保证每个吹气孔3负责将枪头四周的不同位置的物料吹至吸料口1，从而全方位的将枪头附近的物料吹至吸料口1，扩大枪头可吸收的物料的范围，减少吸料过程中对物料的遗漏，从而避免卸料结束后依旧有物料残留在物料袋7或箱子内。
本申请实施例提供的吸枪通过围绕枪头的轴线间隔设置多个吹气孔3，可以将枪头四周的多个位置的物料分别通过不同的吹气孔3吹至吸料口1，从而保证吸料口1可以吸收更多位于枪头四周的物料，减少物料残留。
在一些实施例中，吹气孔3的轴线与枪头的轴线之间具有第二夹角a，第二夹角a的角度值在60度到67.5度之间，以提高将物料吹至吸料口1的准确度。
图2是本申请实施例提供的一种吸枪的剖视结构示意图。如图2所示，吹气孔3的轴线与枪头的轴线之间具有第二夹角a，第二夹角a小于90度。可以理解的是，当吹气孔3的吹气方向与吸料口1的吸料方向之间的夹角过大，例如为钝角时，吹气孔3很难将物料吹至吸料口1的位置，且更容易将物料吹至相反的一端。因此，吹气孔3和吸料口1之间必然存在一个角度，可以使吹气孔3更好的将物料吹至吸料口1。
基于此，本申请实施例提供了一种角度范围，可以保证吹气孔3的吹料效果。具体的，以吹气孔3的轴线和枪头的轴线为基准，当吹气孔3的轴线与枪头的轴线之间的第二夹角a的角度值在60度到67.5度之间时，可以保证吹气孔3将物料吹至枪头的前方，也就是枪头的吸料口1处。
吹气孔3与枪头之间的第二夹角a太大会将物料吹至远离吸料口1的位置，第二夹角a太小则会很容易将吸料口1附近的物料吹走，并且也很难将物料吹至吸料口1。因此，本申请实施例提供的吸枪通过将第二 夹角a的角度值设置在60度到67.5度之间，可以保证吹气孔3吹气的方向能更好的将物料吹至吸料口1，从而减少物料残留，提高吸料效率。
如图1所示，在一些实施例中，枪头为中空结构的圆锥体或棱锥体，以利用枪头的尖部刺破盛装物料的物料袋7。
尖部是指圆锥体或棱锥体的顶部。从几何意义上讲，圆锥体或棱锥体的所有母线的交点，即为圆锥体或棱锥体的尖部。
中空结构可以保证枪头的吸料口1可以更多的吸入物料，圆锥体或棱锥体的顶部有尖，可以保证枪头的顶部为可以刺破物料袋7的尖部，从而可以从物料袋7外部直接刺破物料袋7并进入物料袋7内部进行吸料。
本申请实施例提供的吸枪通过将枪头的结构设置为圆锥体或棱锥体，来确保枪头的顶部为具有一定角度的尖部，从而可以利用枪头直接刺破盛装物料的物料袋7，省去了枪头吸收物料前的对物料袋7的开口步骤。并且，利用枪头自身结构刺破物料袋7，可以保证破开的口子的尺寸贴合枪头尺寸，既避免了根据枪头尺寸确定开口大小的步骤，又避免了在开口处泄露物料。
图3是本申请实施例提供的一种吸枪在第二视角下的结构示意图。如图3所示，在一些实施例中，吸料口1设于圆锥体或棱锥体的锥面上，且吸料口1避开枪头的尖部，以增加尖部的锋利度。
可以理解的是，吸料口1是在枪头的锥面上开的通孔，设有吸料口1的锥面的结构不如没有设置吸料口1的区域的结构牢固。因此，在一种实现方式中，如图1、图2或图3所示，可以将从枪头的尖部向枪头的另一端中间具有一定宽度的区域设为支撑区8，用以增加枪头结构的牢固程度。
吸料口1设置于锥面，避开枪头的尖部，可以使枪头的尖部为圆 锥体或棱锥体的锥尖，从而具有较小的接触面积，以获得较大的压强，使枪头更容易刺破物料袋7。
本申请实施例提供的吸枪通过将吸料口1避开枪头的尖部，可以缩小枪头的尖部与物料袋7的接触面积，从而在同等力度的条件下使枪头具有更大的压强，用较小的力度即可成功刺破物料袋7。
在一些实施例中，结合图1和图2可以看出，枪头的顶部为一个锥尖，锥尖的顶角5具有第一角度b。
在一些实施例中，b的取值，也即圆锥体或棱锥体的顶角5的角度值在30度至60度之间，以保持尖部的锋利度并增加吸料口1组成的吸料区的面积。
当枪头是圆锥体时，顶角5是指以圆锥体的轴线为基准，相互对称的两条母线在圆锥体的尖部的交角。当枪头是棱锥体时，顶角5是指以棱锥体的轴线为基准，相互对称的侧面的中线在棱锥体的尖部的交角。
当顶角5小于30度时，枪头的尖部会非常锋利，但同时会使得圆锥体或棱锥体的侧面积非常的小，从而限制了吸料口1的可设置区域面积，导致吸料口1组成的吸料区的面积变小，而吸料区的面积直接影响单位时间内吸收物料的流量。因此，在顶角5非常小、小于30度的情况下，吸枪的吸料效率也会有明显的降低。
当顶角5大于60度时，圆锥体或棱锥体的侧面积非常的大，吸料口1的可设置区域面积也会很大，因此吸料口1组成的吸料区的面积也变大。但是枪头的尖部的锋利度会变小，枪头的尖部与物料袋7的接触面积变大，从而在同等力度下得到的压强变小，导致要用较大的力才能刺破物料袋7。且锋利度的降低会使枪头在刺破物料袋7时对物料袋7产生撕扯，容易使破口处产生碎屑等杂物，杂物在吸料过程中被吸附在吸料口1 上而对吸料口1造成遮挡，影响吸料进程，增加了物料残留的可能性，降低吸料效率。
当枪头的顶部的顶角5的角度值在30度至60度之间时，枪头的顶部为一个较尖的锥尖，可以快速刺破物料袋7。并且，顶角5的角度值在30度至60度之间时，还可以保证圆锥体或棱锥体的的侧面积，从而保证吸料口1的数量，也保证了吸料区的面积，使得物料从更多吸料口1或更大吸料区处被吸收，从而使枪头单位时间内可以吸收更多的物料，减少物料残留，保证吸料效率。
顶角5太大会降低尖部的锋利度，顶角5太小会导致吸料区的面积过小，造成吸料困难。本申请实施例提供的吸枪将枪头尖部的顶角5的角度值设置在30度至60度之间，选用此角度范围，同时考虑尖部的锋利度和吸料区的面积，做到两者的平衡，从而可以在枪头尖部的锋利度足以刺破物料袋7的同时保证吸料区的面积，进而可以吸收更大范围的物料，减少物料残留，保证吸料效率。
在一些实施例中，顶角5的角度值为45度。圆锥体或棱锥体的顶角5的角度越大，锥面的面积也就越大，但相应的，尖部刺破物料袋7所需要的力也就越大，这意味着若想要足够大的吸料区就必须舍弃吸枪尖部的锋利度。基于此，本申请实施例提供一种角度值，即，当吸枪的顶角5的角度值为45度时，既可以保证吸料区的面积足够大，也可以保证吸枪尖部的锋利度足以顺利刺破物料袋7。
本申请实施例提供的吸枪通过将枪头尖部的顶角5的角度值设置为45度，可以使吸料区的面积最大，以使得吸料效率最大，同时还保证了枪头的锋利度，以确保可以使用较小的力成功刺破物料袋7。
在本申请的又一实施例中，还提供了一种吸料装置，图4是本申 请实施例提供的吸料装置的一种应用场景示意图。如图4所示，本申请实施例提供的吸料装置0可以设置在物料袋7的底部，本申请对一次吸料过程中所用吸料装置的个数不做限制，可以理解的是，设置在物料袋7底部的吸料装置越多，吸料越快，吸料的效率越高。
本申请实施例提供的吸料装置可以包括：
至少一个上述任一实施例的吸枪，用于控制吸枪移动以使得吸枪靠近物料的伸缩装置，和用于向吸枪的吹气管2输入气体的补气装置。伸缩装置控制吸枪移动，可以使吸枪到达任何一个位置吸料。补气装置向吹气孔3源源不断的提供气源，使得吹气孔3可以持续将物料吹至吸料口1。而吸料口1也持续吸收物料，从而使吸枪在吹气孔3和吸料口1的配合下把枪头附近的物料吸收的更彻底，减少物料在物料袋7内的残留。
示例性的，如图1、图2和图3所示，补气装置通过进气口4向吹气管2输入气体，气体从吹气管2的吹气孔3中出来，形成气流以吹送物料。
本申请实施例提供的吸料装置，可以通过伸缩装置控制吸枪在吸料开始时靠近物料，在吸料结束时远离物料，此外，还可以控制吸枪在吸料过程中随着吸料进程伸缩，以在合适的位置吸收物料，并通过补气装置在吸料过程中向吹气管2输入气体，以使气体从吹气孔3流出，将物料吹至枪头的吸料口1处，保证物料被吸料口1吸收，减少物料在物料袋7内残留的同时提高吸料效率。
在一些实施例中，本申请实施例提供的吸料装置还可以包括：
气压控制装置，用于控制吸枪内部的气压低于吸枪外部的气压，以使吸枪外部的物料从吸料口1吸入吸枪内部。气压控制装置可以是空气放大器，也可以是产生吸力的吸气装置。可以理解的是，由于吹气孔3吹 出的气流所产生的虹吸效应，物料会被吹至吸料口1，而通过气压控制装置在吸枪内部产生低于吸枪外部的气压，可以使得吸料口1主动的吸收被吹气孔3吹过来的物料。
本申请实施例提供的吸料装置，可以通过气压控制装置增强吸枪内外的气压差，促使吸枪外部的物料被吸入吸枪内部，确保吸料效果，减少物料残留。
在一些实施例中，本申请实施例提供的吸料装置还可以包括：
管道6，位于吹气管2的内部，与吸枪的远离吸料口1的一端连接，用于传输吸枪吸入的物料。通过吸枪吸入的物料需要转移到另一个位置，用于转移物料的管道6可以根据物料的性质确定，管道6可以是金属材质或非金属材质，本申请对管道6的材质和硬度均不作限定。
本申请实施例提供的吸料装置，可以通过在吸枪的另一端接入管道6，来接收吸枪吸入的物料并通过管道6将其转移。示例性的，如图1所示，吸料装置在枪头远离吸料口1的一端连接一个管道6，从而承接吸料口1吸入的物料，管道6所通向的地方就是吸入的物料要转移到的地方。
本申请实施例提供的吸料装置，可以应用在转移盛放在物料袋7中的物料的情况下。示例性的，以电池的加工工艺流程为例，在开始电池的加工前，需要将所需的粉料准备好，之后按一定配比添加至搅拌生产车间中进行搅拌。其中，粉料一般以吨袋为包装进行运输和上料，吨袋上料是至关重要的一环。
本申请提供的吸料装置可以应用在车间的解包站上，解包站内部为真空，在解包站的底部角落可以放置本申请所提供的吸料装置。
当吨袋被放置在解包站中，设置在解包站底部的吸料装置中的伸缩装置可以控制吸枪向上方移动，吸枪的尖部刺破吨袋并继续移动，直到 枪头插入吨袋中，之后，吹气孔3和吸料口1开始发挥作用，吹气孔3可以将吨袋中藏在各处的粉料也吹至吸料口1，吸料口1则不停的吸料，吹气孔3和吸料口1互相配合，直到将吨袋中的粉料完全吸收。
综上所述，本申请实施例提供的吸枪，通过吹气孔3和吸料口1之间的配合，可以将物料吸收的更彻底，解决了在吸收物料的过程中发生物料残留的问题，提高了吸料的效率。本申请实施例提供的吸料装置，可以控制吸枪移动至吸收物料的位置，并对吸枪的吹气孔3进行补气，提供吹气孔3的气流来源，使之可以在吸料的过程中一直吹气。本申请提供的吸料装置还可以使吸枪内部的气压低于吸枪外部，从而可以将吸枪外部的物料吸入吸枪内部，实现吸料功能。
