技术领域
本申请涉及螺杆阀技术领域，尤其涉及一种螺杆阀及其出胶控制方法。
背景技术
目前，随着中高粘度的含颗粒胶水在不同应用中的发展，颗粒材质种类和颗粒尺寸种类越来越多。由于定转子尺寸单一，现有普通的同心式螺杆阀在实际应用中，无法同时适用于不同颗粒。
磁胶是指胶液中含有氧化铁颗粒。此类胶液的金属颗粒含量高，因此具有密度大、胶水粘度较低的特点。由于磁胶中含有的氧化铁颗粒会对现有的螺杆阀的出胶量控制产生影响，现有螺杆阀及点胶控制器均无法稳定精确地控制出胶量，尤其无法控制小胶量的出胶精度，且胶水滴漏问题严重。
发明内容

另外，螺杆或者定子组件的磁吸力作用可以抵消掉氧化铁颗粒的自重力对出胶量的影响，可以稳定地实现微量出胶。然而，如果没有螺杆或定子组件的磁吸力作用，由于磁胶中氧化铁颗粒的作用，磁胶中金属颗粒含量高，密度大，导致胶水粘度较低，出胶量会因金属颗粒的重力作用大大增加，并且出胶量也会不稳定。本申请的螺杆阀，可以有效避免这些问题，可以实现出胶量稳定，且可以实现微量出胶。
在停止出胶时，由于螺杆或者定子组件对磁胶中的氧化铁颗粒的磁吸力作用，磁胶中氧化铁颗粒可以被螺杆或者定子组件吸附，从而有效避免磁胶因氧化铁颗粒自动产生漏液现象，从而实现快速断胶，防止磁胶滴漏。

进一步地，所述定子上设置有防松螺钉，所述防松螺钉与定子螺纹连接，所述防松螺钉与所述嵌套件的外侧壁相抵紧，以防止所述嵌套件松动。通过拧紧防松螺钉可以防止嵌套件松动，使得嵌套件在定子中的装配更加稳定，避免嵌套件松动引起的出胶量不稳定。

进一步地，在步骤S3之后，所述出胶控制方法还包括：S4，在所述螺杆正转期间，对所述胶液进口的流体压力和所述螺旋槽下端的流体压力进行控制，其中，所述螺旋槽下端的流体压力为Fa，所述胶液进口处的流体压力为Fb，Fa和Fb均沿向下的方向，其中Fa≥Fb，以使得磁胶在所述螺杆的转动和所述磁吸力F1的作用下，向所述螺旋槽的下端运动并从所述螺旋槽下端进入到所述针头中进行出胶量控制稳定的出胶。
进一步地，在步骤S4后，所述出胶控制方法还包括：
S5，在所述螺杆阀停止出胶时，使所述螺杆从正转状态变为反转，其中，所述螺杆反转时间为t，所述螺杆反转时间t后，使所述螺杆停止转动，所述螺杆反转期间和停止转动时，F2≤F1+F3，其中，在所述螺杆反转期间和停止转动后，在所述螺杆或所述嵌套件对磁胶中氧化铁颗粒的吸力F1作用下，磁胶被吸附在所述螺杆或者所述嵌套件上。
在螺杆阀停止出胶时，螺杆反转时间t，可以有效避免磁胶因运动惯性作用滴漏，使得螺旋槽中的磁胶在反转时具有与运动方向相反的推力，可以实现快速停止出胶，且F2≤F1+F3，可以在螺杆反转期间和停止转动时，螺杆或者嵌套件对磁胶中的氧化铁颗粒具有吸附作用，可以有效避免磁胶漏液，并且也可以进一步实现快速停止出胶的作用。
进一步地，步骤S1中，对所述螺杆或者所述嵌套件的加磁量为φ，φ的范围为5mT≤φ≤300mT。对加磁量φ进行控制，可以避免加磁量过大导致磁吸力过大，避免磁吸力过大导致磁胶中的氧化铁颗粒难以从螺旋槽中随磁胶排出，而加磁量过小，则难以实现磁吸力抵消氧化铁颗粒自重对磁胶出胶量的影响。
进一步地，所述螺杆的转速为v，v≤300转/分。螺杆的转速控制在300转/分以内，出胶量精度控制能够更加精确，螺杆的转速超过300转/分，出胶精度会下降。
进一步地，步骤S5中，螺杆的反转时间为0.1秒≤t≤0.6秒。
进一步地，所述螺旋槽下端的流体压力Fa与胶液进口处的流体压力Fb的比值为Fa/Fb＝(1～5):1。将Fa和Fb的比值设定在Fa/Fb＝(1～5):1，能够更好地对Fa和Fb进行控制。
进一步地，步骤S3中，F2+F4-(F1+F3)≥F2，F2为磁胶中加入的氧化铁颗粒的重力，是已知量。将F2+F4-(F1+F3)≥F2，能够使得磁吸力F1对出胶量精度控制的作用更加稳定，出胶量更加稳定，并且出胶量精度控制更高。
进一步地，步骤S5中，0.5×F2≤F1+F3-F2≤F2，且F1+F3-F2≥Fa-Fb。如此，能够使得磁吸力F1对防止磁胶滴漏的作用更加稳定，且可以更进一步地提高快速停止出胶作用的稳定性。
进一步地，步骤S3中，螺杆转动时对磁胶的推力F4＝v×K，其中v是螺杆的转速，K是常数。常数K的取值范围为0.001×F2～0.05×F2，包含端点值0.001×F2和0.05×F2，F2为磁胶中加入的氧化铁颗粒的重力，是已知量。如此，能够通过调整螺杆的转速对推力F4进行控制和调节，便于控制出胶量的精度。
本申请的有益效果是，在螺杆阀转动进行出胶的过程中，通过控制F1≥F2，且F1+F3≤F2+F4，带磁性的螺杆或者嵌套件会对磁胶中的氧化铁颗粒具有磁吸力，磁吸力可以抵消掉氧化铁颗粒自身的重力，避免氧化铁颗粒自身的重力影响出胶量的控制，且在螺杆的推力作用下，磁胶出胶稳定，出胶量控制精度高，并且可以实现微量出胶。
另外，在螺杆或者嵌套件的磁吸力作用下，抵消掉氧化铁颗粒的自重力对出胶量的影响，可以稳定地实现微量出胶。然而，如果没有螺杆或嵌套件的磁吸力作用，由于磁胶中氧化铁颗粒的作用，磁胶金属颗粒含量高，密度大，胶水粘度较低，出胶量会因金属颗粒的重力作用大大增加，并且出胶量也会不稳定，本申请的螺杆阀，则可以有效避免这些问题，可以实现出胶量稳定，且可以实现微量出胶。
在停止出胶时，由于螺杆或者嵌套件对磁胶中的氧化铁颗粒的磁吸力作用，磁胶中氧化铁颗粒可以被螺杆或者嵌套件吸附，从而有效避免磁胶因氧化铁颗粒自动产生漏液现象，从而实现快速断胶，防止磁胶滴漏。

在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
参照图1至图3，本申请的一种螺杆阀100，包括阀座1、驱动件2、定子组件3、螺杆4和针头6。驱动件2安装在阀座1上，定子组件3设置在阀座1上，定子组件3的上端设置有胶液进口11，定子组件3的一侧设置有胶桶9。该胶液进口11与胶桶9通过内部通道或者内部管道相连通。螺杆4与定子组件3活动连接，螺杆4与驱动件2的动力输出端传动连接以驱动螺杆4转动。螺杆4上具有螺旋槽12，该螺旋槽12与该胶液进口11相连通，该螺旋槽12的下端为点a，胶液进口11处为点b。针头6位于定子组件3的下方，针头6与定子组件3相连接，针头6内部的通道与螺旋槽12相连通。
定子组件3包括定子10和嵌套件5，定子10安装在阀座1上，胶液进口11设置在定子10的上端，螺杆4与定子10活动连接。嵌套件5设置在定子10与螺杆4之间，嵌套件5与定子10固定连接，螺杆4在嵌套件5内可转动。螺杆4或者定子组件3具有磁性。例如，螺杆4或者嵌套件5具有磁性。
由于螺杆4或者定子组件3具有磁性(例如，螺杆4或者嵌套件5具有磁性)，磁胶在螺旋槽12中流动时，带磁性的螺杆4或者定子组件3(例如，定子组件3的嵌套件5)对磁胶中的氧化铁颗粒具有磁吸力，抵消掉磁胶中的氧化铁颗粒的重力，消除氧化铁颗粒自身重力对磁胶出胶量精度的影响，便于实现稳定精确地控制出胶量精度。
本申请的螺杆阀100，在螺杆阀100转动进行出胶的过程中，带磁性的螺杆4或者嵌套件5会对磁胶中的氧化铁颗粒具有磁吸力，该磁吸力可以抵消掉氧化铁颗粒自身的重力，避免氧化铁颗粒自身的重力影响出胶量的控制，从而使得出胶量控制精度高。
另外，通过螺杆4或者嵌套件5的磁吸力作用抵消掉氧化铁颗粒的自重力对出胶量的影响，可以稳定地实现微量出胶。相反，如果没有螺杆4或嵌套件5的磁吸力作用，由于磁胶中氧化铁颗粒的作用，磁胶中金属颗粒含量高，密度大，导致胶水粘度较低，出胶量会因金属颗粒的重力作用大大增加，并且出胶量也会不稳定。本申请的螺杆阀100，可以有效避免这些问题，可以实现出胶量稳定，且可以实现微量出胶。
在停止出胶时，由于螺杆4或者嵌套件5对磁胶中的氧化铁颗粒的磁吸力作用，磁胶中氧化铁颗粒可以被螺杆4或者嵌套件5吸附，从而有效避免磁胶因氧化铁颗粒自动产生漏液现象，从而实现快速断胶，防止磁胶滴漏。
定子10的下端设置有紧固件7，针头6的一部分安装在紧固件7中，紧固件7与定子10固定连接。具体地，紧固件7与定子10螺纹连接。紧固件7对针头6起到紧固的作用，方便针头6的安装。定子10和紧固件7均由抗磁质材料制成。定子10和紧固件7均起到隔磁的作用，防止外部磁场对螺杆4或者嵌套件5的磁性产生干扰，也避免外部磁场对磁胶中的氧化铁颗的影响。
嵌套件5的外侧面为圆锥形面。嵌套件5的外侧面设置成圆锥形侧面，可以很好地保证嵌套件5与螺杆4、以及嵌套件5与定子10之间的同轴度，圆锥形侧面可以很好地消除安装嵌套件5时对嵌套件5与定子10之间的间隙的要求。
定子10上设置有防松螺钉8，防松螺钉8与定子10螺纹连接，防松螺钉8与嵌套件5的外侧壁相抵紧，以防止嵌套件5松动。通过拧紧防松螺钉8可以防止嵌套件5松动，使得嵌套件5在定子10中的装配更加稳定，避免嵌套件5松动引起的出胶量不稳定。
本申请还提供了一种螺杆阀的出胶控制方法，该螺杆阀包括驱动件、定子组件、螺杆、针头和紧固件，定子组件包括定子和嵌套件，定子组件的上端设置有胶液进口，螺杆上具有螺旋槽，螺旋槽用于与胶液进口相连通，可选地，该螺杆阀为根据本申请上述任一实施例的螺杆阀100。参考图3，该出胶控制方法包括以下步骤：
S1，对螺杆或者嵌套件进行充磁，使得螺杆或者嵌套件具有磁性充磁；
S2，对螺杆阀进行装配，具体地，将嵌套件安装在定子上，再将针头和紧固件安装在定子的下端，然后再安装螺杆；
S3，在进行点胶时，控制驱动件驱动螺杆正转以使螺杆转动并带动磁胶在螺旋槽中移动，其中，螺杆或者嵌套件对磁胶中氧化铁颗粒的磁吸力为F1，磁胶中氧化铁颗粒的重力为F2，磁胶中胶液的附着力为F3，螺杆转动时对磁胶的推力为F4，其中，F1≥F2，且F1+F3≤F2+F4。
本申请的螺杆阀的出胶控制方法，通过控制F1≥F2，且F1+F3≤F2+F4，在螺杆阀进行出胶时，螺杆或者嵌套件的磁吸力可以抵消掉氧化铁颗粒的重力，且在螺杆的推力作用下，磁胶出胶稳定，出胶量控制精度高，并且可以实现微量出胶。
进一步地，参考图4，在步骤S3之后，该出胶控制方法还可包括：
S4，在螺杆正转期间，对胶液进口的流体压力和螺旋槽下端的流体压力进行控制，其中，螺旋槽下端的流体压力为Fa，胶液进口处的流体压力为Fb，Fa和Fb均沿向下的方向，Fa≥Fb，以使得磁胶在螺杆的转动和磁吸力F1的作用下，稳定地向螺旋槽下端运动，从螺旋槽下端进入到针头中，进行出胶量控制稳定的出胶。
进一步地，参考图4，该出胶控制方法，在步骤S4后，还包括：
S5，在螺杆阀停止出胶期间，使螺杆从正转状态变为反转，其中，螺杆反转时间为t，螺杆反转时间t后，使螺杆停止转动，螺杆反转期间和停止转动时，F2≤F1+F3，其中，在螺杆反转期间和停止转动后，在螺杆或嵌套件对磁胶中氧化铁颗粒的吸力F1作用下，磁胶被吸附在螺杆或者嵌套件上，有效避免磁胶在螺杆反转期间和停止转动时产生漏液。
例如，步骤S5中，螺杆的反转时间0.1秒≤t≤0.6秒。
在螺杆阀停止出胶时，螺杆反转时间t，可以有效避免磁胶因运动惯性作用滴漏，使得螺旋槽中的磁胶在反转时具有与运动方向相反的推力，可以实现快速停止出胶，且F2≤F1+F3，可以在螺杆反转期间和停止转动时，螺杆或者嵌套件对磁胶中的氧化铁颗粒具有吸附作用，可以有效避免磁胶漏液，并且也可以进一步实现快速停止出胶的作用。
步骤S1中，对螺杆或者嵌套件的加磁量为φ，φ的范围为5mT≤φ≤300mT。对加磁量φ进行控制，可以避免加磁量过大导致磁吸力过大，避免磁吸力过大导致磁胶中的氧化铁颗粒难以从螺旋槽中随磁胶排出，而加磁量过小，则难以实现磁吸力抵消氧化铁颗粒自重对磁胶出胶量的影响。
螺杆的转速为v，v≤300转/分。螺杆的转速控制在300转/分以内，出胶量精度控制能够更加精确，螺杆的转速超过300转/分，出胶精度会下降。
螺旋槽下端的流体压力Fa与胶液进口处的流体压力Fb的比值为Fa/Fb＝(1～5):1。将Fa和Fb的比值设定在Fa/Fb＝(1～5):1，能够更好地对Fa和Fb进行控制。
步骤S3中，F2+F4-(F1+F3)≥F2，F2为磁胶中加入的氧化铁颗粒的重力，是已知量。将F2+F4-(F1+F3)≥F2，能够使得磁吸力F1对出胶量精度控制的作用更加稳定，出胶量更加稳定，并且出胶量精度控制更高。
步骤S5中，0.5×F2≤F1+F3-F2≤F2，且F1+F3-F2≥Fa-Fb。如此设置，能够使得磁吸力F1更加稳定地防止磁胶滴漏，且可以更进一步的提高快速停止出胶作用的稳定性。
步骤S3中，螺杆转动时对磁胶的推力F4＝v×K，其中v是螺杆的转速，K是常数。常数K的取值范围为0.001×F2～0.05×F2，包含端点值0.001×F2和0.05×F2，F2为磁胶中加入的氧化铁颗粒的重力，是已知量。如此设置，能够通过调整螺杆的转速对推力F4进行控制和调节，便于控制出胶量的精度。
本申请的出胶控制方法的有益效果是，在螺杆阀转动进行出胶的过程中，通过控制F1≥F2，且F1+F3≤F2+F4，带磁性的螺杆或者嵌套件会对磁胶中的氧化铁颗粒具有磁吸力，该磁吸力可以抵消掉氧化铁颗粒自身的重力，避免氧化铁颗粒自身的重力影响出胶量的控制，且在螺杆的推力作用下，磁胶出胶稳定，出胶量控制精度高，并且 可以实现微量出胶。
另外，螺杆或者嵌套件的磁吸力作用可以抵消掉氧化铁颗粒的自重力对出胶量的影响，可以稳定地实现微量出胶。相反，如果没有螺杆或嵌套件的磁吸力作用，由于磁胶中氧化铁颗粒的作用，磁胶中金属颗粒含量高，密度大，导致胶水粘度较低，出胶量会因金属颗粒的重力作用大大增加，并且出胶量也会不稳定。本申请的螺杆阀，则可以有效避免这些问题，可以实现出胶量稳定，且可以实现微量出胶。
在停止出胶时，由于螺杆或者嵌套件对磁胶中的氧化铁颗粒具有磁吸力作用，磁胶中氧化铁颗粒可以被螺杆或者嵌套件吸附，从而有效避免磁胶因氧化铁颗粒自动产生漏液现象，从而实现快速断胶，防止磁胶滴漏。
