[0037] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0038] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0039] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0040] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0041] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0042] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0043] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application.

It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0044] In the field of glue potting, according to production needs, two liquids of different viscosities, glue A and glue B, are often evenly mixed together to increase the viscosity of the glue. However, the mixed glue is prone to solidification after chemical reaction. Therefore, glue A and glue B need to be stirred by a stirring component when they are mixed. However, as the working time increases, the stirring component may be damaged. If it is not discovered in time, glue A and glue B may solidify, thereby damaging the stirring component and even the mixing glue head.

[0045] Based on the above, please refer to Figures 1 to 3 In this embodiment, a mixing rubber head is proposed, which includes a rubber head body 1, a mixing tube 2, a magnetic switch 3, a stirring component 4 and a magnetic part. The rubber head body 1 is provided with a first glue inlet, a second glue inlet and a glue outlet, and the first glue inlet and the second glue inlet are both connected to the glue outlet; the mixing tube 2 is provided with a dispensing port, which is connected to a mixing chamber provided in the mixing tube 2, and the mixing chamber is connected to the glue outlet; the magnetic switch 3 is provided in the mixing tube 2; the stirring component 4 is provided in the mixing chamber, and the stirring component 4 can rotate around its own axis; the magnetic part is provided in the stirring component 4, and the magnetic part can be periodically arranged relative to the magnetic switch 3. Among them, the shape of the magnetic part is preferably a block or the like. In addition, the magnetic part can be provided in the stirring component 4 by a fixed method such as embedding.

[0046] It can be understood that glue A is delivered to the mixing tube 2 from the first glue inlet, and glue B is delivered to the mixing tube 2 from the second glue inlet. Glue A and glue B can be mixed under the action of the stirring component 4. During the stirring process of the stirring component 4, the magnetic part will rotate accordingly. When the magnetic part rotates to a position relative to the magnetic switch 3, the magnetic switch 3 can be triggered, thereby sending a signal to the detection end. After the detection end receives the signal, the time interval between two adjacent received signals is compared with the expected time interval. If the two are inconsistent, it proves that the stirring component is damaged. Then the staff can replace or repair the stirring component 4 in time, so that the curing phenomenon between glue A and glue B can occur. Among them, the expected interval refers to the time required for the magnetic part to rotate one circle with the stirring component 4. In addition, the magnetic switch 3 is preferably a detection structure such as a reed switch, a magnetic sensor, a magnetic holding switch or a magnetic flap switch.

[0047] In this embodiment, a reed switch is used as an example for illustrative explanation. When the magnetic field of the magnetic component periodically enters the detection area of ​​the reed switch, the two metal reeds of the magnetic switch 3 are periodically fitted together, so that the reed switch can be periodically triggered, and the intervals between two adjacent signal values ​​received by the detection end are the same.

[0048] If the magnetic member is always in the detection area of ​​the reed switch, the two reeds will remain in contact with each other, so that the reed switch can be triggered all the time, which proves that the stirring component 4 has stopped rotating and needs to be repaired.

[0049] If the magnetic member cannot be rotated to the detection area of ​​the reed switch, the two reeds will remain separated, so that the reed switch will not be triggered. This proves that the stirring component 4 has stopped rotating and needs to be repaired.

[0050] If the time when the magnetic part appears in the detection area of ​​the reed switch twice is different, the two metal reeds of the magnetic switch 3 cannot be periodically fitted together, so that the reed switch cannot be triggered periodically, and the intervals between two adjacent signal values ​​received by the detection end are different, which proves that the rotation frequency of the stirring component 4 is different, and it needs to be inspected and repaired.

[0051] It should also be noted that during use of the magnetic switch 3, the detection end for detecting the signal emitted by the magnetic switch 3 can be a detection instrument such as a magnetic field measuring instrument, or the magnetic switch 3 can be connected to a PLC so that the user can monitor the signal emitted when it is triggered.

[0052] In addition, the mixing tube 2 is preferably made of plastic. Since plastic has good corrosion resistance and is cheap, it can be directly replaced when the mixing tube 2 is stained, so as to reduce the cleaning time of the mixing tube 2.

[0053] In this embodiment, the mixing rubber head further includes a driving device 5, which is arranged on the rubber head body 1, and the stirring component 4 is detachably arranged on the driving end of the driving device 5. In practical applications, after the A glue and the B glue enter the mixing chamber, the stirring component 4 can rotate around its own axis under the action of the driving device 5. During the rotation process, the stirring component 4 can not only fully stir the A glue and the B glue, but also make the magnetic field of the magnetic part periodically enter the area of ​​the magnetic switch 3, so that the two metal reeds in the magnetic switch 3 are periodically attached, so that the magnetic switch 3 can periodically send a signal, which is convenient for the operator to observe the working state of the stirring component 4.

[0054] Specifically, the driving device 5 includes a connection seat 51, a servo motor 52 and a coupling 53. The connection seat 51 is arranged on the rubber head body 1, the servo motor 52 is arranged on the connection seat 51, the coupling 53 is arranged at the rotating end of the servo motor 52, and the stirring component 4 penetrates the rubber head body 1 and is connected to the coupling 53. It can be understood that the stirring component 4 penetrates the rubber head body 1, and then is connected to the coupling 53, and then can rotate around its own axis under the action of the servo motor 52. Among them, the connection between the stirring component 4 and the coupling 53 is preferably a detachable connection to facilitate the replacement of the stirring component 4.

[0055] In this embodiment, the mixing glue head also includes a first closing component 6, which is disposed at the first glue inlet, and the first closing component 6 is configured to open or block the first glue inlet. In practical applications, when it is not necessary to inject glue into the mixing chamber, the first glue inlet is blocked by the first closing component 6, and when it is necessary to inject glue into the mixing chamber, the first glue inlet is opened again by the first closing component 6. In addition, the mixing glue head also includes a second closing component 7, which is disposed at the second glue inlet, and the second closing component 7 is configured to open or block the second glue inlet. The structures of the first closing component 6 and the second closing component 7 are consistent, and the specific structure of the first closing component 6 is used as an example for explanation below.

[0056] The first closing component 6 includes a first flow channel plate 61, a second flow channel plate 62, a blocking member 63 and an elastic member 64. A glue flow channel is arranged inside the first flow channel plate 61, one end of the glue flow channel is connected to the external glue supply mechanism, and the other end is connected to the first glue inlet. An opening is arranged on the first flow channel plate 61; the second flow channel plate 62 is connected to the first flow channel plate 61, and a slide groove is arranged on the second flow channel plate 62, and the groove of the slide groove is arranged opposite to the opening; the blocking member 63 is slidably connected to the slide groove, and the blocking member 63 has an open state of opening the first glue inlet or a blocked state of blocking the first glue inlet; the elastic member 64 is compressed and arranged between the blocking member 63 and the second flow channel plate 62, and can be elastically deformed when the glue supply mechanism supplies glue, so as to have elastic potential energy to restore the deformation after the glue supply mechanism is closed, and can switch the blocking member from the blocked state to the open state. In actual application, under the action of the elastic member 64, the blocking member 63 can block the glue flow channel. When the glue supply mechanism starts to supply glue, the glue enters the glue flow channel and the elastic member 64 can be compressed under the action of the glue pressure, so that the blocking member 63 switches from the blocking state to the open state. The elastic member 64 is preferably a telescopic spring.

[0057] Furthermore, the first closing component 6 further includes a glue diaphragm 65, which is disposed between the first flow channel plate 61 and the second flow channel plate 62, and the glue diaphragm 65 is elastic. It is understandable that the glue diaphragm 65 can seal the opening so that when glue flows in the glue flow channel, the glue can enter the second flow channel plate 62, which can not only avoid the waste of glue, but also improve the service life of the blocking member 63 and the elastic member 64.

[0058] In addition, the first closing component 6 also includes a blowing member, which is arranged on the second flow channel plate 62, and the blowing member is connected to the inside of the slide, and the blowing member blows air between the blocking member 63 and the bottom of the slide, so that the blocking member 63 switches from the open state to the blocked state. It can be understood that when the stirring component 4 is damaged and needs to be stopped for inspection, the blowing member blows air into the slide, and when the air pressure in the slide is greater than the glue pressure in the glue flow channel, the blocking member 63 will switch from the open state to the blocked state again.

[0059] In particular, the second flow channel plate 62 includes a bottom plate 621 and a connecting plate 622 for connecting to the first flow channel plate 61, the connecting plate 622 is provided with a through hole, the through hole and the bottom plate 621 form a slide groove, the blowing piece is provided on the bottom plate 621; an air film 66 is provided between the bottom plate 621 and the connecting plate 622, and the air film 66 is elastic. It can be understood that the provision of the air film 66 can prevent the gas blown by the blowing piece from entering the glue flow channel, thereby ensuring the quality of the mixed glue.

[0060] In this embodiment, the first closing component 6 further includes a connector 8, which is disposed between the glue flow channel and the first glue inlet. It is understandable that one end of the connector 8 is connected to the glue flow channel, and the other end is connected to the first glue inlet, so that the first flow channel plate 61 can be removed, thereby facilitating the cleaning of the glue head body 1.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
