As shown in fig. 1 to 3, 5 and 7, in the embodiment of the present invention, the glue injection device further includes a driving structure in driving connection with the push rod 27. The driving structure drives the push rod 27, so that the push rod 27 can drive at least two pump rods 223 to move simultaneously relative to the pump body 222, thereby achieving the purpose of pumping the colloid into the pump cavity 221 or pumping the colloid in the pump cavity 221 simultaneously, and improving the working efficiency.

Preferably, the driving structure is a motor or a cylinder, etc.

As shown in fig. 1, 2 and 7, in the embodiment of the present invention, the structure of the first glue injection mechanism 20 is the same as that of the second glue injection mechanism 30, and the push rod 27 of the first glue injection mechanism 20 and the push rod of the second glue injection mechanism 30 are integrated. First injecting glue mechanism 20 and second injecting glue mechanism 30 all are used for injecting the colloid into thoughtlessly glue pipe 10, make two colloids mix in thoughtlessly glue pipe 10, avoid two kinds of colloids to mix postcure, cause the extravagant problem of glue. Through the arrangement, the structure of the glue injection device can be simplified, and the glue injection device is convenient to assemble and operate. Because the push rod 27 of the first glue injection mechanism 20 and the push rod of the second glue injection mechanism 30 form an integrated structure, the push rod 27 can drive the pump rod 223 of the first glue injection mechanism 20 and the pump rod of the second glue injection mechanism 30 to move synchronously, the first glue injection mechanism 20 and the second glue injection mechanism 30 pump in glue or pump out glue simultaneously, so that the first glue injection mechanism 20 and the second glue injection mechanism 30 can inject glue into the glue mixing tube 10 simultaneously, the two kinds of glue are mixed and injected in the shortest time, the problem of glue waste caused by solidification after mixing of the two kinds of glue can be avoided, and the working efficiency can be improved.

Preferably, the push rod 27 of the first glue injection mechanism 20 and the push rod of the second glue injection mechanism 30 are integrally formed or separately arranged.

Of course, in an alternative embodiment not shown in the drawings of the present application, the push rod 27 of the first glue injection mechanism 20 and the push rod of the second glue injection mechanism 30 may be two structures independent of each other according to actual needs.

As shown in fig. 1 to 7, in the embodiment of the present invention, the pump body 224 of the first glue injection mechanism 20 has an accommodating cavity, a first through hole and a second through hole, both of which are communicated with the accommodating cavity, the mounting structure 24 is fixedly mounted in the accommodating cavity of the pump body 224, the glue outlet 254 is communicated with the first opening 241 through the first through hole, and the third opening 243 is communicated with the first overflow groove 41 through the second through hole, so that the mounting structure 24 can be mounted on the pump body 224, and the glue can smoothly flow in the first glue injection mechanism 20; the mounting structure 24 of the first glue injection mechanism 20 and the mounting structure of the second glue injection mechanism 30 form an integrated structure, the pump body 224 of the first glue injection mechanism 20 and the pump body of the second glue injection mechanism 30 form an integrated structure, the pump body end cover 225 of the first glue injection mechanism 20 and the pump body end cover of the second glue injection mechanism 30 form an integrated structure (the groove 226 on the pump body end cover 225 of the first glue injection mechanism 20 is communicated, the groove on the pump body end cover of the second glue injection mechanism 30 is communicated), so that the mounting structure is convenient to process and easy to assemble.

Of course, in the alternative embodiment of the present application, the structure of the first glue injection mechanism 20 may be different from that of the second glue injection mechanism 30, or the structure of the first glue injection mechanism 20 may be the same as that of the second glue injection mechanism 30, but the number of the reciprocating pumps of the first glue injection mechanism 20 is different from that of the second glue injection mechanism 30, or a conventional glue injection mechanism in the art is adopted as the first glue injection mechanism 20 or the second glue injection mechanism 30, so that the purpose of injecting the glue into the glue mixing pipe 10 to mix the two kinds of glue can be achieved as well.

In the embodiment of the utility model, the mixed glue injection operation process of the glue injection device is as follows:

the glue A is poured into the glue cylinder 26 of the first glue injection mechanism 20, the glue B is poured into the glue cylinder of the second glue injection mechanism 30, the glue A and the glue B are separated independently by adopting a double glue cylinder, a double switching structure and a reversing valve, and the problems that the glue A and the glue B are converged in advance and are solidified due to mixing and the operable time is shortened are better solved.

The switching structure is a rod piece, the reversing valve is a three-way structure designed on the rod piece, and the reversing valve can be respectively communicated with the rubber cylinder, the reciprocating pump and the supporting seat. When the switching structure is at 0 degree, the channel of the reversing valve to the supporting seat is blocked, the rubber cylinder, the valve body and the reciprocating pump are communicated to form a channel, and after air pressure is supplied to the rubber cylinder, the glue enters the reciprocating pump (as shown in figures 3 and 4).

When the switching structure is at 90 degrees, the channel of the reversing valve to the rubber barrel is blocked, the reciprocating pump, the reversing valve, the supporting seat and the rubber mixing pipe are communicated to form a channel, the push rod is pushed downwards, the rubber is pushed towards the rubber mixing pipe, and the downward movement stroke of the push rod determines the using amount of the rubber (as shown in fig. 5 and 6).

The AB glue is generally mixed by weight, not volume, and is precisely mixed, otherwise the AB glue may not be poured out. And the material is not reusable. Therefore, the amount of the glue needs to be accurately controlled, the amount of the glue is saved, and the waste of the glue is reduced.

The AB glue injection device known by the inventor has the problems of complicated and huge mechanism, large glue container, large glue consumption and inconvenience for micro injection; the necessary cleaning structure is lacked, so that the phenomenon that glue blocks the glue channel is often caused, and the cleaning becomes extremely complicated.

As shown in fig. 7, in the embodiment of the present invention, the amount and the ratio of the glue a and the glue B can be controlled by controlling the size and the number of the reciprocating pumps and the capacity of the glue cylinder, so as to more effectively perform the ratio of the glue a and the glue B.

In the technical scheme of this application, the injecting glue device is more retrencied, and it is more convenient to clear up. The cleaning process of the glue injection device is as follows: cleaning liquid (such as water) can be poured into the rubber sleeve, then the cleaning liquid is gradually poured into the rubber mixing pipe and discharged according to the mixed rubber injection operation process of the rubber injection device, and the cleaning of the rubber injection device can be completed. The cleaning process can be repeated for multiple times according to actual needs so as to thoroughly clean the glue injection device. The cleaning process is simple, convenient and quick.

In the embodiment of the utility model, the first glue injection mechanism 20 and the second glue injection mechanism 30 respectively inject glue into the glue mixing pipe 10, so that the problem that the glue pipeline is blocked and is very difficult to clean due to the fact that glue A and glue B are mixed and cured in advance can be avoided; the glue injection device is simple, and convenience in operation can be improved.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: the first glue injection mechanism and the second glue injection mechanism are both connected with the glue mixing pipe, when the reversing valve is located at the first position, glue (such as glue A) in the glue storage device is conveyed into the reciprocating pump, when the reversing valve is switched to the second position, the reciprocating pump is used for conveying the glue in the glue storage device into the glue mixing pipe, namely, the first glue injection mechanism can inject the glue (such as glue A) into the glue mixing pipe; the second glue injection mechanism can inject glue (such as glue B) into the glue mixing pipe; the first glue injection mechanism and the second glue injection mechanism can respectively inject glue into the glue mixing pipe, and the glue is mixed and injected out of the glue mixing pipe; the process of injecting the colloid into the rubber mixing tube, mixing and injecting is a continuous process, the operation is convenient, and the problem of glue waste caused by solidification after mixing of two kinds of colloids can be avoided; the glue injection device can conveniently perform mixing operation and glue injection, avoids the problem of glue waste, and can improve the working efficiency. The first glue injection mechanism comprises at least two reversing valves and at least two reciprocating pumps which are arranged corresponding to the at least two reversing valves, when the reversing valves are located at first positions, the reciprocating pumps are communicated with the glue storage equipment and can pump glue in the glue storage equipment into the reciprocating pumps, when the reversing valves are located at second positions, the reciprocating pumps are communicated with the glue mixing pipes, and the glue in the reciprocating pumps can be pumped out to the glue mixing pipes; the glue injection device of this application realizes carrying glue to the purpose of mixing the rubber tube through switching at least two switching-over valves and utilizing the pump-in and the pump-out of two at least reciprocating pumps. The glue injection device can complete the conveying process of a large amount of glue in a certain time, namely, the glue injection device can convey a large amount of glue in a certain time range, and can meet the actual production requirement; and the amount of the glue pumped in and out can be controlled by controlling each reciprocating pump, so that the accurate control of the amount of the glue conveyed to the glue mixing pipe is realized. In addition, in the technical scheme of the application, the switching structure is used for switching the reversing valve between the first position and the second position, and the reversing valve can be switched between the first position and the second position under the driving of the switching structure; the switching structure is connected with all the reversing valves to form an integral structure, so that the switching structure can drive at least two reversing valves to synchronously move, the at least two reversing valves are switched between a first position and a second position at the same time, the purpose of conveying the glue to the glue mixing pipe is achieved, and the working efficiency can be improved; this arrangement also facilitates ease of manufacture or assembly and contributes to improved structural strength and stability.
