[0002] Based on existing glue pumps, the inlet and outlet are in the same location, used for both introducing and discharging glue. Therefore, air can easily enter the pump body during glue intake or discharge. Once air enters the pump body, the glue flow rate becomes difficult to control, leading to instability in the glue flow. Utility Model Content

[0003] The purpose of this invention is to provide a glue pump to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a glue pump, including a pump body, wherein the pump body is provided with a glue inlet and a glue outlet, and the glue inlet is located below the glue outlet; it also includes a control valve, wherein the glue inlet and the glue outlet are respectively connected to the control valve, and the glue inlet path and the glue outlet path are separated from each other through the control valve.

[0006] As a preferred embodiment of this utility model: the valve body of the control valve is further provided with a first interface, a second interface, a third interface, and a fourth interface; wherein, the glue inlet is connected to the second interface, and the glue outlet is connected to the third interface; by rotating the ball inside the control valve, the first interface and the second interface are connected, and the connection between the third interface and the fourth interface is cut off; by resetting the ball, the ball cuts off the connection between the first interface and the second interface, and completes the connection between the third interface and the fourth interface.

[0007] As a preferred technical solution of this utility model: the inner side of the pump body is further provided with a diaphragm, and the diaphragm is moved inside the pump body by a driving member, so that the pump body can draw external glue into the pump body through the first interface or pump out the glue that has entered the pump body through the fourth interface.

[0008] As a preferred technical solution of this utility model: the driving component includes a cylinder, and a piston is provided inside the cylinder, and the end of the piston away from the cylinder is connected to the diaphragm.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0020] Please see Figure 1-5 The present invention provides an embodiment of a glue pump, comprising a pump body 1, wherein the pump body 1 is provided with a glue inlet 4 and a glue outlet 5, the glue inlet 4 and the glue outlet 5 are located on one side of the pump body 1, and the glue outlet 5 is located above the glue inlet 4; it also includes a control valve 6, wherein the glue inlet 4 and the glue outlet 5 are respectively connected to the control valve 6, and the glue inlet path and the glue outlet path are separated from each other through the control valve 6.

[0021] In summary, because the glue pump uses control valve 6 to isolate and prevent the glue inlet and outlet routes from overlapping, it effectively solves the problem of air residue buildup inside the pump body 1 caused by glue entering through the same path. Furthermore, by controlling the glue inlet and outlet routes with control valve 6, even if air enters the pump body 1, air removal becomes simple and convenient. Air entering the pump body 1 can be discharged along with the glue through the outlet route, resulting in more thorough air removal.

[0022] To ensure the normal entry and exit of glue, the control valve 6 is equipped with a ball 60 inside. By rotating the ball 60 inside the control valve 6, the pump body 1 can draw in glue or pump out the drawn-in glue.

[0023] Specifically, the control valve 6 is further provided with a first interface 61, a second interface 62, a third interface 63, and a fourth interface 64 on its valve body; wherein, the glue inlet 4 is connected to the second interface 62, and the glue outlet 5 is connected to the third interface 63; by rotating the ball 60 inside the control valve 6, the first interface 61 and the second interface 62 are connected, and the connection between the third interface 63 and the fourth interface 64 is cut off; by resetting the ball 60, the ball 60 cuts off the connection between the first interface 61 and the second interface 62, and completes the connection between the third interface 63 and the fourth interface 64.

[0024] In summary, by rotating or resetting the ball 60 inside the control valve 6, the glue entry path and the glue discharge path can be isolated from each other, and there is no overlap in the glue entry and discharge processes, thus effectively reducing the entry of air.

[0025] Based on the above scheme, a diaphragm 2 is also provided on the inner side of the pump body 1. A driving member 3 causes the diaphragm 2 to move inside the pump body 1, so that the pump body 1 can draw in external glue through the first interface 61 or pump out glue that has entered the pump body 1 through the fourth interface 64. Specifically, when air enters through the air inlet / outlet 35 and exhausts through the air outlet 7, causing the diaphragm 2 to move to the right, glue is drawn in. When air enters through the air outlet 7 and exhausts through the air inlet / outlet 35, causing the diaphragm 2 to move to the left, glue flows outward.

[0026] The driving component 3 includes a cylinder 30, and a piston 33 is provided inside the cylinder 30. The end of the piston 33 away from the cylinder 30 is connected to the diaphragm 2. Preferably, the driving component 3 is a cylinder.

[0027] Furthermore, since the piston 33 is equipped with a magnetic ring 32 at one end within the cylinder 30, and the cylinder 30 is also equipped with a first detection unit 31 and a second detection unit 34, the position of the piston 33 within the cylinder 30 is obtained through the first detection unit 31 and the second detection unit 34. Therefore, by using the two detection units to obtain the specific position of the piston 33, the external control system can provide a signal to the control valve 6, so that the control valve 6 can cause the ball 60 to rotate or reset according to the position of the piston 33. The first detection unit 31 and the second detection unit 34 are preferably magnetic sensors. The control valve 6 is preferably a four-way ball valve, which, compared to the one-way valve used in ordinary diaphragm pumps, has the characteristics of self-cleaning and good sealing.

[0028] To extend the service life of the diaphragm 2, the pump body 1 is also equipped with an air hole 7, which is connected to an external air control valve 8 via a pipe. Therefore, when the air control valve 8 supplies air to the pump body 1, it can push the diaphragm 2 to the left as a whole, thus preventing damage to the diaphragm 2 due to uneven force. At the same time, when air enters through the air inlet 35 on the drive component 3, it causes the piston 33 to move to the right. At this time, the air control valve 8 switches the air hole 7 to the exhaust state, so that the gas inside the pump body 1 can be freely discharged. In addition, the cylinder 30 is also equipped with a muffler 36, which can block dust and reduce noise. The air control valve 8 is a commercially available product, and its model is usually a 4V210 solenoid valve. The connection method of the air compressor for the air control valve 8 can be directly referred to the existing technology, so it will not be described in detail here.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
