[0025] Example

[0026] Depend on Figures 1 to 4As shown, the embodiment of the present invention provides a non-stop glue supply device, comprising a main body 1, a switching ball valve 2, a glue barrel 3 and at least two glue supply components 4 arranged in the main body. The top of the glue barrel 3 extends out of the main body 1, and the glue barrel 31 is provided with a closing lid 31 on the top. When the closing lid 31 is opened, glue can be added to the glue barrel 3. The closing lid 31 is provided with a handle 37 for convenient opening of the closing lid; the bottom of the glue barrel 3 is connected to a glue outlet pipe 32, and the glue outlet pipe 32 is provided with glue outlets 33 corresponding to the number of glue supply components 4. In this application, the provision of two glue supply components 4 is used as an example for description, that is, there are two glue outlets 33, and each glue outlet 33 is connected to a corresponding glue supply component 4 through a pipeline. Each glue supply assembly 4 includes a glue storage cylinder 41 and a driving member. The bottom of the glue storage cylinder 41 is provided with a glue inlet 42 connected to the glue outlet 33 and a glue supply port 43 for supplying glue. The glue inlet 42 and the glue supply port 43 are both equipped with a switch valve 46; a piston assembly is provided inside the glue storage cylinder 1, and the piston assembly includes a piston 44 and a piston rod 45 that are engaged with each other. The piston rod 45 extends out of the top of the glue storage cylinder 41 and is connected to the driving member, so that the driving member can drive the piston 45 to move back and forth along the glue storage cylinder; each glue supply port 43 is connected to the switching ball valve 2 through a pipeline. The switching ball valve 2 is arranged outside the main body 1 and is selectively connected to the glue supply port 43 to realize the switching of the glue supply pipeline.

[0027] In this embodiment, when the glue supply device is in operation, the lid 31 of the glue barrel 3 is opened and glue is manually added to the glue barrel 3. The on-off valve on the glue supply port 43 is closed and the on-off valve on the glue inlet 42 is opened. At this time, the driving member drives the piston 45 upward, creating a negative pressure in the glue storage cylinder 41, thereby drawing glue from the glue barrel 3 into the glue storage cylinder 41. When the piston moves upward to a designated position, the glue is drawn. The on-off valve on the glue inlet 42 is then closed and the on-off valve on the glue supply port 43 is opened. The driving member drives the piston 45 downward, pressing the glue in the glue storage cylinder 41 to supply glue until the piston 45 reaches its lowest limit. By switching the ball valve 2 to switch the glue supply lines, the two glue supply components can alternately draw glue and supply glue, achieving non-stop glue supply. When the glue in the glue barrel 3 is exhausted, the lid 31 need only be opened to refill, without disassembling the glue barrel, making operation convenient and quick. The glue is pumped out and supplied by the piston principle, which can avoid bubbles generated by the contact between glue and air during glue supply.

[0028] Reference Figure 3 and Figure 4As shown, the drive element includes a telescopic cylinder 47 and a connecting rod 48. The piston rod 45 is connected to the telescopic end of the telescopic cylinder 47 via the connecting rod 48. Two telescopic cylinders 47 are provided, symmetrically arranged on either side of the glue storage cylinder. An exhaust pipe 5 is provided within the piston assembly, and a degassing exhaust port 51 is provided at the top of the piston rod 45, which is connected to the exhaust pipe 5. The degassing exhaust port 51 is equipped with an exhaust valve. After the piston 45 moves up to the designated position to complete the glue extraction, the switch valves on the glue inlet 42 and the glue supply port 43 are closed. The telescopic cylinder 47 continues to extend, driving the piston 45 upward, expelling bubbles in the glue through negative pressure. The exhaust valve is then opened to exhaust the air, completing the glue degassing process.

[0029] Reference Figure 2 、 Figure 5 As shown, a transparent tube 34 is connected to the side wall of the glue barrel 3, through which the glue level can be checked for glue addition. A liquid level sensor 35 and a switch ball valve 36 are installed on the glue outlet pipe 32. The liquid level sensor 35 is used to sense whether there is glue in the glue outlet barrel 31. When the glue is exhausted, an alarm is issued, prompting the user to add glue or manually close the switch ball valve 36.

[0030] Furthermore, the device includes a control system, which includes an alarm 6 and a switching control panel 7 mounted on the main body. The alarm 6 is electrically connected to the liquid level sensor 35. When the liquid level sensor 35 senses that the glue has reached the lowest level, it sends an alarm message to the alarm 6, which then sounds an alarm. The switching control panel 7 is electrically connected to the switching ball valve 2 and the drive element. The switching panel 7 is equipped with a pressure regulating switch, a switching switch, and a display panel, which can be used to adjust the pressure in the glue storage cylinder, switch the glue supply line, and display information such as the remaining glue level.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
