Please refer to fig. 1 to fig. 3, which illustrate an embodiment of the glue supply system of the present invention.

Referring to fig. 1, fig. 2, and fig. 3, the present embodiment provides a novel glue supply system 100, which includes:

the pre-storing device 1 comprises a pre-storing barrel 11 for storing glue; and the number of the first and second groups,

supply mucilage binding 2, including supplying mucilage binding main part 21 and extraction mechanism 22, supply the inside confession of being formed with of mucilage binding main part 21 and glue the chamber, supply glue the chamber have with prestore the first mouth of glue that advances of bucket 11 intercommunication and be used for with some adhesive deposite equipment intercommunication, extraction mechanism 22 is used for with prestore glue in the bucket 11 is followed advance gluey mouthful and take out and follow first mouth of glue is discharged.

In the technical scheme that this embodiment provided, prestore device 1 is used for prestoring glue, prestores device 1 and includes that one prestores bucket 11, prestores bucket 11 inside and is formed with the chamber that is used for holding glue. The glue supply device 2 comprises a glue supply device main body 21 and an extraction mechanism 22, a cavity is formed inside the glue supply device main body 21 and called as a glue supply cavity, a glue inlet and a first glue outlet are formed in the surface of the glue supply device main body 21, the glue inlet is communicated with the cavity of the pre-storage barrel 11, and the first glue outlet is communicated with external glue dispensing equipment.

Through increasing the glue prestore device 1 of prestoring and adopting the cavity extraction formula to supply glue, reduce and trade gluey time and trade gluey frequency, increase the production product shipment volume.

It should be noted that, in order to enable the extracting mechanism 22 to extract the glue pre-stored in the pre-storage barrel 11 into the glue supplying cavity inside the glue supplying device main body 21 at one time, the volume of the glue supplying cavity inside the glue supplying device main body 21 cannot be smaller than the volume of the inner cavity of the pre-storage barrel 11. Further, in order to prevent corrosion, the pre-storage tub 11, the glue supply device main body 21, and the extraction mechanism 22 are all made of 304 stainless steel.

The specific form of the extracting mechanism 22 is various, and may be a structure similar to a water pump to directly extract the glue in the pre-storage barrel 11 to the glue dispensing device, or may be designed as a piston 221. The piston 221 draws the glue in the pre-storage barrel 11 into the glue supply cavity by making an expansion cavity stroke; by making a stroke of the compression cavity, the glue in the glue supply cavity is pressed out from the first glue outlet to the glue dispensing equipment. In the present embodiment, the glue in the pre-storage barrel 11 is extracted and extruded to the dispensing device by the piston 221. The extracting mechanism 22 includes a piston 221, the piston 221 is movably disposed in the glue supplying chamber, and the piston 221 can move toward or away from a certain chamber wall of the glue supplying chamber. When the piston 221 is far away from a cavity wall in a certain direction, the space between the piston 221 and the glue supply cavity is enlarged, and the process is called as enlarging the cavity stroke; similarly, when the piston 221 approaches a wall of a chamber in a certain direction, the space between the piston 221 and the glue supplying chamber is reduced, which is called as a compression chamber stroke. In this embodiment, the piston 221 is movably disposed in the glue supplying chamber in the up-down direction. Therefore, when the piston 221 moves upwards, the space enclosed by the piston 221 and the bottom wall of the glue supply cavity is enlarged, and the air pressure is smaller than the external atmospheric pressure, so that the glue in the pre-storage barrel 11 can be sucked. When the piston 221 moves downwards, the space enclosed by the piston 221 and the bottom wall of the glue supplying cavity becomes smaller, and the piston 221 extrudes glue from the first glue outlet to the glue dispensing device. The extracting mechanism 22 in this embodiment has a simple structure and high efficiency, and can continuously supply glue to the dispensing equipment.

Air bubbles in the glue may be caused during transportation, and the air bubbles may break to generate excessive gas or cause air residue due to improper operation. Therefore, the function of the designed exhaust channel is to exhaust the redundant gas or residual air generated by the bubble destruction. An exhaust valve 222 is added to enable control of the exhaust process.

Further, in the present embodiment, in order to enable the piston 221 to move, a driving device 3 is required, and the driving device 3 is used for driving the piston 221 to perform an expansion chamber stroke or a compression chamber stroke. The specific form of the driving device 3 is various, and may be a cylinder or a motor, as long as it can drive the piston 221 to move.

Specifically, in the present embodiment, the driving device 3 includes two driving cylinders, a first driving cylinder 31 and a second driving cylinder 32. Referring to fig. 2, the first driving cylinder 31 is disposed at the left side of the glue supply device body 21 and closely attached to the outer wall of the left side of the glue supply device body 21; the second driving cylinder 32 is disposed at the right side of the glue supply device body 21 and closely attached to the outer wall of the right side of the glue supply device body 21. The first driving cylinder 31, the second driving cylinder 32 and the glue supply device main body 21 are fixedly connected together through a cylinder connecting block 224. The cylinder connecting block 224 has three side-by-side holes, which are fixed together. Further, in order to fix the power output shafts of the first driving cylinder 31 and the second driving cylinder 32 together with the piston 221, a connecting block 223 is provided between the three cylinders. Referring to fig. 2, the top of the piston 221 is the end above the glue supply device body 21, and the principle of fixing the three together by the connecting block 223 is the same as that described above, and will not be described again.
