Fig. 1 to 4 show a preferred embodiment of a double-cylinder plunger-type glue supply pump of the type of the present application, which comprises a total of two glue supply units, each comprising: the glue storage device comprises a cylinder sleeve 1, a piston, a driving cylinder 2, a glue inlet 3, a glue outlet 4, a glue inlet valve and a glue outlet valve, wherein the cylinder sleeve 1 is internally provided with a glue storage cavity, the piston is movably arranged in the glue storage cavity, the driving cylinder 2 is connected with the piston to drive the piston to move, the glue inlet 3 is communicated with the glue storage cavity, the glue outlet 4 is communicated with the glue storage cavity, the glue inlet valve is used for connecting/blocking a communication path between the glue inlet and the glue storage cavity, and the glue outlet valve is used for connecting/blocking a communication path between the glue outlet and the glue. And the driving cylinder 2 is simultaneously in circuit connection with the glue inlet valve and the glue outlet valve.
During operation, the glue inlet valve and the glue outlet valve are only opened alternatively, and the other valve is in a closed state, specifically:
when the driving cylinder drives the piston to extract glue to the glue storage cavity, the glue inlet valve connects the glue inlet with the communication path of the glue storage cavity, and the glue outlet valve blocks the communication path of the glue outlet with the glue storage cavity, namely, the glue inlet valve is opened and the glue outlet valve is closed. When the driving cylinder drives the piston to discharge the glue in the glue storage cavity outwards, the glue inlet valve blocks the communication path between the glue inlet and the glue storage cavity, and the glue outlet valve connects the glue outlet with the communication path between the glue storage cavity, that is, the glue outlet valve is opened and the glue inlet valve is closed.
In practical application, the glue inlet 3 is connected with an upstream glue storage barrel by a glue inlet pipeline, and the glue outlet 4 is connected with a downstream glue utilization device by a glue outlet pipeline. Initially, the glue storage cavity in the cylinder sleeve 1 is empty and has no glue. After receiving the glue pumping instruction, the driving cylinder 2 drives the piston to move from left to right in fig. 2, and meanwhile, the glue inlet valve and the glue outlet valve which are in circuit connection with the driving cylinder 2 also perform corresponding actions, namely the glue inlet valve is opened to connect the communication path between the glue inlet and the glue storage cavity, and the glue outlet valve is closed to block the communication path between the glue outlet and the glue storage cavity. Thereby the glue in the upstream glue storage barrel is extracted from the glue inlet 3 to the glue storage cavity in the cylinder sleeve 1. When the glue in the cylinder sleeve 1 reaches the required amount, the driving cylinder 2 receives a glue discharging instruction to drive the piston to freely move leftwards in the figure 2, meanwhile, a glue inlet valve and a glue outlet valve which are in circuit connection with the driving cylinder 2 also perform corresponding actions, namely the glue inlet valve is closed to block a communication path between the glue inlet and the glue storage cavity, and the glue outlet valve is opened to communicate the glue outlet with the communication path of the glue storage cavity. So that the glue in the glue storage cavity is injected into the downstream glue utilization equipment from the glue outlet 4.
In addition, in order to realize the linkage operation of the two glue supply units and further ensure the continuous glue supply to the downstream glue equipment, the driving cylinders 2 of the two glue supply units are electrically connected, that is, the driving cylinder 2 of one glue supply unit is electrically connected with the driving cylinder 2 of the other glue supply unit. When the driving cylinder 2 in the first glue supply unit performs the glue discharging action, the driving cylinder 2 in the second glue supply unit performs the glue pumping action; and when the glue in the glue storage cavity of the first glue supply unit is emptied and the driving cylinder 2 in the second glue supply unit performs the glue discharging action, the driving cylinder 2 in the first glue supply unit performs the glue pumping action. The glue is continuously and uninterruptedly supplied to the downstream glue application equipment in such a circulating way.
Above-mentioned advance gluey valve includes: the glue inlet valve body is arranged on a communication path of the glue inlet and the glue storage cavity, and the glue inlet valve cylinder 5 is connected with the valve body and acts by the valve body. The driving cylinder 2 is electrically connected with the glue inlet valve cylinder 5, so that the driving cylinder 2 and the glue inlet valve cylinder 5 are linked,
go out gluey valve and advance gluey valve structure basically the same, it includes: a glue outlet valve body arranged on the communication path of the glue outlet and the glue storage cavity, and a glue outlet valve cylinder 6 connected with the glue outlet valve body to drive the glue outlet valve body to act. The driving cylinder 2 is specifically in circuit connection with the glue outlet valve cylinder 6, so that the linkage of the driving cylinder 2 and the glue inlet valve cylinder 5 is realized.
In addition, because the piston is easy to damage due to long-term movement in the cylinder sleeve 1, the present embodiment is further provided with a lubricating oil cup 7 for lubricating the piston, and lubricating oil in the lubricating oil cup 7 infiltrates a contact surface (i.e., a movable matching surface) between the piston and the wall of the glue storage cavity, so as to lubricate the movement of the piston.
In order to prevent the lubricating oil from permeating into the interior of the cylinder sleeve 1, i.e. the rubber storage cavity, the piston is provided with an oil seal structure for sealing the lubricating oil.
It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present application, and the present application is not limited thereto. All equivalent changes and modifications made according to the spirit of the main technical scheme of the application are covered in the protection scope of the application.
