[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1As shown, a glue spraying device for processing a container bottom plate comprises a frame 1 and a conveyor belt 2 mounted on the frame 1. The container bottom plate can be placed on the conveyor belt 2 and moved by the conveyor belt 2. In order to be able to perform glue spraying on the moving container bottom plate, a glue outlet pipe head 5 is fixedly connected to the upper side of the frame 1 through a bracket group. The glue outlet pipe head 5 is connected to a glue adding mechanism through a conveying pipe 6. The glue adding mechanism is any device that can convey glue to the inside of the glue outlet pipe head 5.

[0021] A discharge trough is provided at the lower side of the discharge pipe head 5, and the discharge trough is divided into a plurality of small discharge troughs arranged in a row. The discharge pipe head 5 is also equipped with a plurality of electrically controlled opening and blocking groups adapted to the small discharge troughs. The small discharge troughs include an opening state and a blocking state. The electrically controlled opening and blocking groups are used to control the small discharge troughs to switch between the opening state and the blocking state.

[0022] When the conveyor belt 2 drives the container bottom plate to move, the corresponding small discharge trough is adjusted to an open state according to the area on the upper side of the conveyor belt 2 where glue needs to be sprayed, so that the glue can be sprayed on the corresponding area of ​​the container bottom plate. In this way, when the conveyor belt 2 drives the container bottom plate to move, the entire glue spraying work on the side of the container bottom plate can be completed at one time, thereby improving work efficiency.

[0023] Among them, Figure 1-2 As shown, in order to reduce the phenomenon of glue leaking through the gaps between the multiple electrically controlled opening blocking groups, multiple glue outlet heads 7 are fixedly connected to the lower side of the glue outlet pipe head 5, and the multiple small material outlet grooves are multiple glue outlets 8 independently opened inside the glue outlet head 7. The upper part of the glue outlet 8 is connected to the glue outlet pipe head 5, and the glue can be discharged through the glue outlet 8;

[0024] And, if Figure 2-4 As shown, the longitudinal section of the glue outlet 8 is an isosceles trapezoid, and the upper side length of the isosceles trapezoid is smaller than the lower side length, so that the glue can be sprayed over a wider range when passing through the glue outlet 8, and the area between the two glue outlets 8 is sprayed with glue.

[0025] like Figure 2-3 As shown, the electrically-controlled opening blocking group includes an electrically-controlled moving group mounted on the glue dispensing head 7, on which is mounted a baffle 9 which can be moved to the lower side of the glue dispensing head 7 to block the lower opening of the glue outlet 8. The electrically-controlled moving group can drive the baffle 9 to move forward and backward, and by moving in the front-to-back direction of the glue dispensing head 7, the moving stroke of the baffle 9 can be reduced, making switching convenient.

[0026] Here, the electric control moving group refers to a device that can drive the baffle 9 to move forward and backward, such as an electric push rod, a motor screw combination, etc.;

[0027] In order to adjust the position of the baffle 9 more quickly, this technical solution selects another solution, which is as follows: Figure 2-3As shown, the electric control moving group includes a small bracket 10 fixedly connected to the front side of the glue outlet 7, the lower part of the front end of the small bracket 10 is fixedly connected to the end frame 11, the baffle 9 is slidably connected to the lower side of the small bracket 10, and a return spring 14 is installed between the baffle 9 and the end frame 11. Under the action of the return spring 14, the baffle 9 can be pushed to the lower side of the glue outlet 8 by the thrust of the return spring 14 to block the glue outlet 8;

[0028] The side surfaces of the end frame 11 and the baffle 9 that are close to each other are fixedly connected with an electromagnet 13 and a magnet sheet 12 respectively. When the electromagnet 13 is energized, it is magnetically attracted to the magnet sheet 12, thereby pulling the magnet sheet 12 and the baffle 9 through magnetic force, so that the baffle 9 no longer blocks the lower opening of the glue outlet 8. Under the action of magnetism and elastic force, the baffle 9 can move faster.

[0029] And, if Figure 1 As shown, the bracket group includes a bracket body 3 fixedly connected to the upper side of the frame 1, and a vertically arranged electric push rod 4 is mounted on the bracket body 3. The output end of the electric push rod 4 is fixedly connected to the rubber outlet hose head 5, so that the height of the rubber outlet hose head 5 can be adjusted by the electric push rod 4 to adapt to different container bottom plates.

[0030] When in use, place the container bottom plate on the conveyor belt 2, and move the container bottom plate through the conveyor belt 2. While the container bottom plate is moving, adjust the corresponding small discharge trough to an open state according to the area on the upper side of the conveyor belt 2 where glue needs to be sprayed, so that glue can be sprayed on the corresponding area of ​​the container bottom plate;

[0031] During the process of the conveyor belt 2 moving the container bottom plate, the states of the multiple small discharge troughs are continuously adjusted through the above scheme until the conveyor belt 2 completes the movement of the container bottom plate;

[0032] In summary, this technical solution, by setting up multiple small discharge troughs that can adjust the state according to the glue spraying area on the upper side of the conveyor belt 2, can complete the entire glue spraying work on the side of the container bottom plate at one time when the conveyor belt 2 drives the container bottom plate to move, thereby improving work efficiency.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
