[0001] The utility model relates to bag making equipment, in particular to a glue feeding mechanism of a bag making machine. Background Art
[0002] Bag making machine is a special equipment for automatic production of packaging bags. In the production process of packaging bags, the traditional bag making machine needs to dip the glue in the glue box through the glue dispensing mechanism, and then stick the glue on the packaging bag base material. This glue feeding mechanism that uses glue to be poured into the glue box has the following defects in actual use: 1. The amount of glue required is large, and the glue at the bottom is often difficult to be used, resulting in a waste of glue; 2. When dipping in glue, the glue level in the glue box will gradually decrease, which will cause the amount of glue dipped to gradually decrease until the next glue replenishment, resulting in a certain difference in the amount of glue applied each time, affecting the quality and stability of the glue application; 3. The setting of the glue amount of this structure is often difficult to adjust, resulting in poor flexibility in its use. Utility Model Content

[0018] As shown in the figure, the utility model discloses a glue feeding mechanism of a bag making machine, including a glue feeding roller 2 and a glue leveling roller 3 which are arranged in cooperation. In the present embodiment, the diameter of the glue feeding roller 2 is larger than the diameter of the glue leveling roller 3, and the rotation speed of the glue leveling roller 3 is faster than the rotation speed of the glue feeding roller 2. This arrangement can facilitate the glue leveling roller 3 to better and faster level the glue on the glue feeding roller. The glue feeding roller 2 is connected to the first motor through the first synchronous wheel transmission group 4 (the synchronous belt and the synchronous wheel connected to the output end of the first motor are not shown in the figure), and the glue leveling roller 3 is connected to the second motor through the second synchronous wheel transmission group 5 (the synchronous belt and the synchronous wheel connected to the output end of the second motor are not shown in the figure). By controlling the first and second motors and transmitting through the synchronous belt transmission group, the glue feeding roller 2 and the glue leveling roller 3 can be driven to rotate. Baffles 6 are provided at both ends of the glue feeding roller 2 and the glue leveling roller 3. The glue feeding roller 2, the glue leveling roller 3 and the baffles 6 together enclose a glue storage space. The glue feeding roller 2 and the glue leveling roller 3 are connected to corresponding rotation driving components. The glue feeding roller 2 is rotatably set on the first movable frame 7, and the glue leveling roller 3 is rotatably set on the second movable frame 15. It also includes a movable driving component that can drive the first and second movable frames to move. Specifically, the movable driving component includes a first adjusting cam 8 and a second adjusting cam 19. The first adjusting cam 8 is connected to one end of the first adjusting rod 11, and the second adjusting cam 19 is connected to one end of the second adjusting rod 16. The adjusting rods are all connected with handles 23. The first movable frame 7 is swingably set on the frame, and a first spring 13 is pressed on one side of the first movable frame 7, so that the first extrusion block 9 on the first movable frame 7 is pressed on the first adjusting cam 8. The second movable frame 15 is swingably set on the frame, and a second spring 21 is pressed on one side of the second movable frame 15, so that the second movable frame 15 is pressed on the second adjusting cam 19. Furthermore, a first connecting rod 10 is provided on the first movable frame 7, and the first connecting rod 10 passes through a first positioning block 12 fixed on the frame, and a first pressing plate 14 is provided at one end of the first connecting rod 10, and a first spring 13 is pressed tightly between the first positioning block 12 and the pressing plate 14, and a second connecting rod 18 is provided on the second movable frame 15, and the second connecting rod 18 passes through a second positioning block 20 fixed on the frame, and a second pressing plate 22 is provided at one end of the second connecting rod 18, and a second spring 21 is pressed tightly between the second positioning block 20 and the second pressing plate 22. In addition, a liquid level sensor 24 aligned with the glue in the glue storage space is installed on the baffle 6, and the liquid level sensor 24 can control the glue supply component to pour glue into the glue storage space, wherein the glue supply component is a glue pump body component, which is a common structure on the market, so it will not be repeated, and the amount of glue in the glue storage space is monitored in real time by the liquid level sensor 24 to ensure that there is always a sufficient amount of glue supplied to the glue storage space for glue supply operation. A glue collecting box 1 is arranged below the glue supply roller 2 and the glue leveling roller 3 to receive glue dripping from the glue supply roller 2 and the glue leveling roller 3 .
[0019] The working principle of the utility model is as follows: when it is necessary to perform glue feeding operation, glue is poured into the glue storage space, and then the glue feeding roller 2 and the glue leveling roller 3 are controlled to rotate towards each other, and the glue leveling roller 3 will evenly transfer the glue in the glue storage space to the entire glue feeding roller 2, and the glue dispensing component completes the glue feeding operation by contacting the glue layer on the outer wall of the glue feeding roller 2; when it is necessary to clean the glue feeding roller 2 and the glue leveling roller 3, the glue feeding roller 2 and the glue leveling roller 3 are controlled to rotate in opposite directions, and the glue in the glue storage space is thrown out to facilitate cleaning; when it is necessary to adjust the thickness of the glue layer on the glue feeding roller, the first and second adjusting cams can be controlled to rotate, driving the first and second movable frames elastically pressed on the first and second adjusting cams to swing, and then the gap between the glue feeding roller 2 and the glue leveling roller 3 is fine-tuned, so as to achieve fine-tuning of the thickness of the glue layer on the glue feeding roller 2 and complete the adjustment of the glue feeding amount.
[0020] The structure of the utility model adopts a structure in which a glue feeding roller and a glue leveling roller are arranged in cooperation. A certain amount of glue is poured into the glue storage space, and the glue leveling roller rotates to evenly transfer the glue to the glue feeding roller, and then the glue is transferred to the glue dispensing mechanism through the glue feeding roller, thereby replacing the traditional glue box structure. The glue can be fully utilized and the waste of glue can be avoided. The thickness of the glue on the glue feeding roller is the same as the gap between the glue feeding roller and the glue leveling roller, thereby ensuring that the glue feeding amount each time remains consistent, and effectively improving the glue feeding quality and stability. At the same time, by controlling the action of the first and second movable frames, the gap between the glue feeding roller and the glue leveling roller can be fine-tuned, and the thickness of the glue on the glue feeding roller can be fine-tuned, and the glue feeding amount can be adjusted to meet different glue feeding needs and further improve its flexibility of use.
