[0002] From electronics, electroacoustics to communications, digital and LED, no matter which industry, it is full of dispensing products. As the demand increases, the requirements for dispensing are also getting higher and higher, including high precision, high efficiency, high intelligence and so on.

[0003] When the existing dispensing machine is in operation, due to the rapid feeding of the feeding mechanism, the feeding will also end after the dispensing is completed. However, at the moment when the feeding is just completed, due to the weight of the glue itself or other reasons, a part of the glue will remain at the dispensing nozzle. When waiting for the subsequent workpiece to be transported under the dispensing nozzle, the glue remaining at the dispensing nozzle will drip onto the workpiece or the machine, resulting in glue waste.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] A glue supply mechanism used in a glue dispensing machine, such as Figures 1 to 3As shown, it includes a glue barrel frame 1, and a limiting sleeve 3, a driving ring 4, an elastic member 5, and a push rod 8 set up at one end of the glue barrel frame 1; a mounting frame 12 is integrally formed at one end of the glue barrel frame 1, and an electric push rod 13 facing the glue barrel frame 1 is provided on the mounting frame 12 through bolts. The driving end of the electric push rod 13 is connected to a pushing frame 14 through bolts, and a pushing cylinder 15 facing the glue barrel frame 1 is installed on the pushing frame 14 through bolts;

[0019] The driving end of the pushing cylinder 15 is fixedly connected to the push rod 8 by bolts and a flange. The driving ring 4 is sleeved on the push rod 8. The limiting sleeve 3 is sleeved on the driving ring 4. A connecting part 2 is provided at one end of the glue barrel frame 1. The connecting part 2 has a first annular sleeve 9 and a second annular sleeve 11 arranged coaxially. The elastic member 5 is established between the first annular sleeve 9 and the second annular sleeve 11. The outer peripheral wall of the first annular sleeve 9 is integrally formed with a male thread. The limiting sleeve 3 is integrally formed with a female thread corresponding to the male thread. The elastic member 5 is in contact with the driving ring 4. The elastic member 5 has elastic potential energy that pushes the driving ring 4 away from the connecting part 2.

[0020] In the above embodiment, when glue is needed, the glue barrel is fixed on the glue barrel rack 1, the push rod 8 is fixedly connected to the propulsion part on the glue barrel, and then the electric push rod 13 and the pushing cylinder 15 are started at the same time, so that the electric push rod 13 pushes the pushing rack 14 to slide, and at the same time, the pushing cylinder 15 pushes the push rod 8 to slide, so that the sliding rack can push the cylinder 15 to move, and then the pushing cylinder 15 pushes the glue barrel to squeeze out the glue. When the glue dispensing is completed, the electric push rod 13 is powered off, and the pushing cylinder 15 is stopped at the same time, so that the elastic member 5 pushes the driving ring 4 away from the glue barrel rack 1. Since the driving ring 4 and the pushing rack 14 fits together, making the pushing frame 14 away from the glue barrel frame 1, prompting the pushing cylinder 15 to drive the push rod 8 to slide away from the glue barrel frame 1, so that the push rod 8 is recovered, and the push rod 8 drives the propulsion part of the glue barrel to slide, thereby recovering the glue in the dispensing nozzle, preventing the glue from accumulating at the dispensing nozzle and falling, causing waste; at the same time, the staff can rotate the limit sleeve 3 according to the glue output at the dispensing nozzle, so that after the limit sleeve 3 is rotated, the distance between the support platform 6 and the first limit surface 7 can be adjusted, so that the distance between the elastic member 5 pushing the drive ring 4 can be adjusted, thereby achieving the effect of adjusting the amount of recovered glue.

[0021] In summary:

[0022] By setting a purpose of pushing the glue pushing assembly as a whole away from the glue barrel rack 1 on the glue barrel rack 1, when the glue pushing assembly as a whole moves, it drives the pushing part on the glue barrel to slide, and recovers part of the squeezed glue, thereby preventing glue from accumulating at the glue dispensing nozzle, causing glue to fall, and preventing glue waste. At the same time, the staff can rotate the limit sleeve 3 according to the glue output at the glue dispensing nozzle, so that after the limit sleeve 3 is rotated, the distance between the support platform 6 and the first limit surface 7 can be adjusted, so that the distance that the elastic member 5 pushes the drive ring 4 can be adjusted, thereby achieving the effect of adjusting the amount of recovered glue.
