[0030] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0031] like Figure 1 and Figure 2 As shown, it is a structural schematic diagram of an embodiment of the utility model, which provides an automatic glue supply system for a glue coating machine, including an upper glue coating mechanism, a lower glue coating mechanism and two glue supply mechanisms respectively connected to the upper glue coating mechanism and the lower glue coating mechanism, and the glue liquid is transported into the upper glue coating mechanism and the lower glue coating mechanism through the glue supply mechanism to realize automatic glue supply.

[0032] The upper gluing mechanism is used to apply glue to the upper surface of the paper tape 9, and includes an upper gluing roller 1, an upper scraper assembly 2, an upper glue spraying hose 3 and a gluing tank 4. An upper sol tank is formed between the upper gluing roller 1 and the upper scraper assembly 2. The upper glue spraying hose 3 transports glue liquid into the upper sol tank. The glue tank 4 is arranged below the upper sol tank. The glue supply mechanism transports the glue liquid to the upper sol tank through the upper glue spraying hose 3. After gluing the upper surface of the paper tape 9, excess glue enters the gluing tank 4.

[0033] The lower glue coating mechanism is used to coat the lower surface of the paper tape 9 with glue, and comprises a lower glue coating roller 5, a lower scraper assembly 6, a lower glue spraying pipe 7 and a lower glue tank 8. A lower sol tank is formed between the lower glue coating roller 5 and the lower scraper assembly 6. The lower glue spraying pipe 7 transports glue to the lower sol tank. The lower glue tank 8 is arranged below the lower sol tank. The glue supply mechanism transports the glue to the lower sol tank through the lower glue spraying pipe 7 to coat the lower surface of the paper tape 9 with glue, and the excess glue enters the lower glue tank 8.

[0034] For the upper glue coating mechanism, the glue supply mechanism is arranged between the upper glue spraying pipe 3 and the upper glue groove 4; for the lower glue coating mechanism, the glue supply mechanism is arranged between the lower glue spraying pipe 7 and the lower glue groove 8.

[0035] Specifically, the glue supply mechanism includes a glue storage tank 10 and a liquid level meter 11 arranged in the glue storage tank 10. The glue storage tank 10 is connected to the upper glue spray hose 3 / lower glue spray hose 7 via a first pipe 15. A glue supply pump 16 is provided on the first pipe 15. The glue liquid in the glue storage tank 10 is transported to the upper sol tank / lower sol tank through the first pipe 15 by the glue supply pump 16. Preferably, the glue supply pump 16 is a diaphragm pump.

[0036] The glue storage tank 10 is connected to the upper glue tank 4 / lower glue tank 8 via the second pipeline 17, so as to transport the glue liquid in the upper glue tank 4 / lower glue tank 8 to the glue storage tank 10 for reuse.

[0037] The glue storage tank 10 is connected to the glue supply unit via a third pipeline 18. A glue replenishing valve 19 is provided on the third pipeline 18. The glue replenishing valve 19 is a solenoid valve. The liquid level meter 11 and the glue replenishing valve 19 are respectively connected to the control unit signal. Figure 3 As shown, the glue liquid level in the glue storage tank 10 is monitored in real time by the liquid level meter 11 and the signal is transmitted to the control unit. When the glue liquid level in the glue storage tank 10 is at a low level, the control unit opens the glue liquid replenishing valve 19 to transport the glue liquid to the glue storage tank 10. When the liquid level meter 11 detects that the glue liquid is at a high level, the glue liquid replenishing valve 19 is closed to maintain the current level, thereby realizing automatic glue supply.

[0038] In order to prevent the glue liquid temperature from being too low and affecting the quality of the finished glue film paper, a heating element 12 is provided at the bottom of the glue storage tank 10, and a temperature measuring component 13 is provided in the glue storage tank 10, wherein the heating element 12 can adopt the heating element in the prior art, and the temperature measuring component 13 is a temperature sensor, and the heating element 12 and the temperature measuring component 13 are respectively connected to the control unit signal, such as Figure 4 As shown, the temperature of the glue liquid is monitored in real time by the temperature measuring component 13. When the temperature of the glue liquid is lower than the set value, the heating element 12 is turned on to heat the glue liquid. When the temperature of the glue liquid meets the set value, the heating element 12 is turned off to keep the glue liquid at a suitable temperature to meet the production requirements.

[0039] In this example, the heating element 12 is disposed in the interlayer at the bottom of the glue storage tank 10, and the connector of the heating element 12 extends outside the glue storage tank 10 to facilitate connection to the control unit.

[0040] In order to further optimize the implementation effect of the utility model, a filter screen 14 arranged along the vertical direction is provided in the glue storage tank 10, and the glue storage tank 10 is divided into a first accommodating chamber and a second accommodating chamber by the filter screen 14, wherein the first pipe 15 is connected to the first accommodating chamber, and the second pipe 17 and the third pipe 18 are connected to the second accommodating chamber, and the glue liquid entering the second accommodating chamber from the upper glue tank 4 / lower glue tank 8 or entering the second accommodating chamber from the glue supply unit enters the first accommodating chamber after impurities are filtered out by the filter screen 14, so as to be used for gluing the paper tape 9, thereby avoiding the influence of impurities on the gluing and ensuring the quality of the product.

[0041] In this example, the liquid level meter 11 is arranged in the first accommodating chamber, and the temperature measuring component 13 is arranged in the second accommodating chamber.

[0042] In order to facilitate the connection between the glue supply mechanism and the upper glue coating mechanism and the lower glue coating mechanism, a first quick-connect joint 20 connected to the first pipeline 15 is provided on the upper glue spraying hose 3 / lower glue spraying hose 7, and a second quick-connect joint 21 connected to the first pipeline 15 is provided at the bottom of the glue storage tank 10. A third quick-connect joint 22 connected to the second pipeline 17 is provided on the upper glue tank 4 / lower glue tank 8, and a fourth quick-connect joint 23 connected to the second pipeline 17 and a fifth quick-connect joint 24 connected to the third pipeline 18 are provided at the upper end of the glue storage tank 10. The above-mentioned quick-connect joints are quick-connect joints commonly used for pipeline connection in the prior art, and the specific structure is not repeated in this utility model.

[0043] The working principle of the utility model is:

[0044] A certain amount of glue is injected into the glue storage tank 10 through the third pipe 18 and the glue replenishing valve 19 is closed. The glue in the glue storage tank 10 enters the upper sol tank / lower sol tank through the first pipe 15, the upper glue spraying pipe 3 / lower glue spraying pipe 7 under the action of the glue supply pump 16. The paper tape 9 is glued under the action of the upper glue coating roller 1 / lower glue coating roller 5, the upper scraper assembly 2 / lower scraper assembly 6. The excess glue flows back to the glue storage tank 10 through the upper glue tank 4 / lower glue tank 8 and the second pipe 17. During the glue coating process, the liquid level meter 11 monitors the liquid level of the glue in the glue storage tank 10 in real time. When the glue level is at a low level, the control unit opens the glue replenishing valve 19 to replenish the glue in the glue storage tank 10 until the glue is at a high level and then closes the glue replenishing valve 19. At the same time, the temperature measuring component 13 monitors the temperature of the glue in real time. When the glue temperature is lower than the set value, the heating element 12 is turned on to heat the glue. When the temperature of the glue meets the set value, the heating is stopped.

[0045] In summary, the glue supply system can realize automatic glue supply and automatic heating of the glue liquid to ensure product quality.

[0046] The above examples are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
