[0031] The following will further describe the present utility model in detail with reference to the attached drawings.

[0032] As Figures 1-4 shown, the present utility model discloses a glue supply device of a gear pump, including:

[0033] A glue supply assembly, including a glue bucket 1 and a glue pushing piece 2, and the glue pushing piece 2 is arranged on the upper side of the glue bucket 1;

[0034] A glue outlet assembly, including a gear pump 3 and a driving piece 4 connected to the glue bucket 1, the gear pump 3 is provided with a glue inlet 31 and a glue outlet 32, and the driving piece 4 drives the gear pump 3 to rotate;

[0035] A control assembly, including a control knob 5 and a control box 6, and the control knob 5 is arranged on the control box 6 to control the glue outlet speed.

[0036] The advantage of adopting the above technical solution is that the glue pushing piece 2 presses the glue in the glue bucket 1 out and enters the gear pump 3, and the gear pump 3 supplies the glue. The gear pump 3 can increase the glue supply pressure, make the glue outlet uniform, be suitable for using various viscosity glues, have a stable glue outlet, and quickly supply the glue.

[0037] In some embodiments, a space for accommodating a glue cylinder is provided inside the glue bucket 1. The glue cylinder is vertically placed inside the glue bucket 1 and includes a containing part for containing glue. An extrusion part is provided on the upper side of the containing part, and glue is discharged from the lower side of the containing part by pressing the extrusion part. The glue bucket 1 is provided with an upper cover 11, and the upper cover 11 is rotatably connected to the glue bucket 1 through a connecting piece 12.

[0038] Before discharging glue, place the glue cylinder filled with glue into the glue bucket 1, and then cover the upper cover 11 to perform the automatic glue discharging operation. After the glue discharging is completed, rotate and open the upper cover 11 to replace the new glue cylinder, which is convenient to replace and improves the processing efficiency.

[0039] In some embodiments, the output end of the glue pushing member 2 passes through the upper cover 11 and extends into the glue bucket 1, and an extrusion plate 7 is installed at the end. The extrusion plate 7 is a disc-shaped plate. As the glue pushing member 2 is driven, the extrusion plate 7 moves downward to continuously extrude the glue cylinder to discharge glue, and the glue enters the glue discharging assembly to discharge glue, ensuring uniform glue discharging and no residual glue in the glue cylinder.

[0040] In some embodiments, the driving member 4 is a driving motor. The driving motor is connected with a speed reducer 41, and the speed reducer 41 is connected with the gear pump 3 to drive the rotation of the gear set inside the gear pump 3. The gear set includes a driving gear and a driven gear. The driving gear is connected with the speed reducer 41. Through continuous meshing and extrusion of the driving gear and the driven gear, the glue discharging pressure is increased, and at the same time, uniform glue discharging is ensured. The gear pump 3 is also provided with a waste glue outlet.

[0041] The setting of the speed reducer 41 is used to cooperate with the driving motor to adjust the glue discharging speed. The setting of the gear pump 3 increases the glue discharging pressure and ensures uniform glue discharging, which is applicable to different glue discharging speeds and different types of glue, and has the advantages of simple structure, uniform flow rate, and reliable operation.

[0042] In some embodiments, the glue pushing member 2 is a cylinder. The cylinder is connected to a manual valve 8. The manual valve 8 is fixed on the upper side of the upper cover 11. The air inlet on the pressure regulating valve 9 is connected to the air source, and the air outlet is connected to the manual valve 8. During use, close the manual valve 8 (pull up the button located on the manual valve 8). At this time, the retraction length and retraction time of the cylinder are controlled by the air outlet on the upper side of the manual valve 8. After replacing the glue cylinder, open the manual valve 8 (press the button) to control the extension of the output end of the cylinder. After the processing is completed, close the manual valve 8 again, and a new glue-filled glue cylinder can be replaced continuously. The manual valve 8 pressurizes the glue bucket while controlling the extension of the cylinder to obtain a greater glue discharging pressure.

[0043] The setting of the manual valve 8 is used to open and close the cylinder. Through manual control, it is convenient to replace the glue cylinder. The setting of the pressure regulating valve 9 can adjust the pressure and speed of the cylinder to achieve different glue supply speeds.

The lower end of the rotary fixing handle 13 is hinged to the fixing member 14. The upper cover 11 is provided with a pressing groove, and the side of the rotary fixing handle 13 is provided with an annular protrusion for cooperating with the pressing groove to press. When it is necessary to open the upper cover 11 to replace the glue cartridge, the rotary fixing handle 13 is rotated to the side, and the annular protrusion disengages from the pressing groove, and the upper cover 11 can be opened for replacement. The structure is simple.

[0045] In some embodiments, it further includes a fixed bottom plate 15. The side of the fixed bottom plate 15 is provided with a push-pull handle 16, and the bottom of the fixed bottom plate 15 is provided with walking wheels. The glue supply assembly, the glue discharging assembly and the control assembly are all installed on the fixed bottom plate 15. The entire glue supply device can be moved, so that different devices and different production lines can use a glue discharging device, greatly saving production costs and making the use more flexible.

[0046] In some embodiments, the bottom of the glue bucket 1 is connected to the glue inlet 31 through a pipeline. The glue coming out of the glue bucket 1 enters the glue discharging assembly to achieve uniform glue discharging. At the same time, the glue outlet 32 is provided with a glue discharging pipe and a glue discharging head to supply the glue to a designated position.

[0047] Furthermore, a controller 61, a solenoid valve group 62 and a driver 63 are arranged in the control box 6. The control knob 5 is connected to the controller 61. The driver 63 drives the motor and the reducer 41 to rotate and receives the instructions of the controller 61 to change the glue discharging speed of the gear pump 3. The glue discharging speed is controlled by the control knob 5, replacing the use of a touch screen, reducing the processing cost and simplifying the control operation.

[0048] For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
