Description

Technical Field

[0001] The utility model belongs to the field of coating and gluing, and particularly relates to a precise control system for the amount of gluing. Background Art

[0002] In the prior art, the coating and gluing process requires precise control of the amount of gluing, and the concentration of the glue will undoubtedly affect the amount of gluing. However, in the current gluing system, there is no function for monitoring the glue concentration.

[0003] For example, a previously disclosed thermal paper coating device (application number 201720522821.0) may include a glue roller, a scraper, a film pressing roller, a glue disc, a glue tube and a glue circulation system. The film pressing roller can be raised and lowered above the glue roller. The PET film to be coated is pressed onto the glue roller by the film pressing roller. The glue tube and the scraper are sequentially arranged on the upper side of the glue roller on both sides of the film pressing roller along the rotation direction of the glue roller. The glue disc is arranged below the glue roller to receive the glue dripping from the glue roller. The glue circulation system provides fresh glue to the glue tube and receives glue from the glue outlet of the glue disc. In this device, the glue circulation system has the above-mentioned defects of the prior art. Utility Model Content

[0004] In order to solve the above problems, the technical purpose of the utility model is to provide a precise control system for the amount of glue applied, which can monitor the glue concentration in real time and improve the accuracy of the amount of glue applied.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A precise glue quantity control system, characterized by comprising:

[0007] A coating trough for holding glue for coating;

[0008] A storage container for storing glue, wherein the storage container is located below the coating material tank;

[0009] A first delivery pipeline, wherein both ends of the first delivery pipeline are respectively connected to a storage container and a coating material tank, and a first pump is arranged on the first delivery pipeline;

[0010] A second delivery pipeline, wherein both ends of the second delivery pipeline are respectively connected to a storage container and a coating material tank;

[0011] A detection pipeline, both ends of which are connected to the storage container, and a second pump and a concentration detector are arranged on the detection pipeline.

[0012] In this system, the glue in the storage container is transported from the first delivery pipeline to the coating material tank by the first pump, and the glue in the coating material tank is transported back to the storage container from the second delivery pipeline under the action of gravity, so that the glue is circulated and transported between the storage container and the coating material tank, which can ensure that the difference in glue concentration between the storage container and the coating material tank is small. The second pump extracts the glue in the storage container through the detection pipeline, and discharges it back to the storage container after detecting the glue concentration with a concentration detector, so that the glue concentration can be known and monitored in real time, thereby improving the accuracy of the glue application.

[0013] Furthermore, a stirrer for stirring the glue is arranged in the storage container, and the stirrer can evenly stir the glue in the storage container.

[0014] Furthermore, both ends of the detection pipeline are connected to the lower end and the upper end of the storage container respectively.

[0015] Furthermore, both ends of the first conveying pipeline are connected to the lower end of the storage container and the coating material tank respectively, and both ends of the second conveying pipeline are connected to the upper end of the storage container and the coating material tank respectively.

[0016] Furthermore, the system also includes a dilution pipeline and a dilution container for storing a diluent for diluting the glue, wherein both ends of the dilution pipeline are connected to the dilution container and the storage container respectively, and a valve is provided between the dilution pipeline and the dilution container. The opening and closing of the valve can be controlled according to the glue concentration monitored in real time to control the diluent to dilute the glue in the storage container.

[0017] Furthermore, the dilution container is located above the storage container, and two ends of the dilution pipeline are respectively connected to the lower end of the dilution container and the upper end of the storage container.

[0018] The beneficial effect of the utility model is that, in the system, the glue in the storage container is transported from the first delivery pipeline to the coating material tank by the first pump, and the glue in the coating material tank is transported back to the storage container from the second delivery pipeline under the action of gravity, so that the glue is circulated and transported between the storage container and the coating material tank, which can ensure that the difference in glue concentration between the storage container and the coating material tank is small, and the second pump extracts the glue in the storage container through the detection pipeline, and discharges it back to the storage container after detecting the glue concentration through the concentration detector, so that the glue concentration can be known, the glue concentration can be monitored in real time, and the accuracy of the glue application amount can be improved.
