Through the setting of the interlocking control mechanism 9, the interlocking control mechanism 9 includes an electric cabinet 10 that is electrically connected to the first electric pump 4, the second electric pump 6, the fixing frame 12 and the gluing valve 14. At the same time, the electric cabinet 10 is electrically connected to the controller 11 with a DCS system. When the glue machine 1 breaks paper, the gluing valve 14 will be closed. At this time, the closing of the gluing valve 14 will transmit a signal to the electric cabinet 10 to issue a paper break alarm. Then the electric cabinet 10 will transmit the signal to the controller 11, so that the DCS system in the controller 11 is interlocked to shut down the first electric pump 4 and the second electric pump 6. The interlocking signal of the DCS system in the controller 11 is used to control the start and stop of the first electric pump 4 and the second electric pump 6, so that the entire process does not require human intervention, achieves full automation, and greatly improves production efficiency.

[0025] In this embodiment, Figures 1-4As shown, a slide rail 15 is fixedly installed on the surface of the electrical cabinet 10, and two protective plates 16 are slidably installed on the slide rail 15. A plurality of magnetic blocks 17 are inlaid on the side where the two protective plates 16 are close to each other. A fixed plate 18 is fixedly installed on the surface of the fixed frame 12, and a spring 19 is fixedly installed on one side of the fixed plate 18. A support rod 20 is fixedly installed on the spring 19, and a clamping rod 21 is fixedly installed on one end of the support rod 20 that passes through the fixed plate 18 and the spring 19. A plurality of clamping blocks 22 are fixedly installed on the surface of the flow meter 13, and a clamping groove adapted to one end of the clamping rod 21 is provided on the clamping block 22. By setting the slide rail 15 and the protective plate 16, the two protective plates 16 are pulled to slide on the slide rail 15 to fit together. The fitted protective plates 16 can cover the controller 11 inside, thereby protecting the controller 11 and preventing the controller 11 from being damaged by collision. By setting the magnetic block 17, the protective plates 16 after fitting can be fixed by the adsorption of multiple magnetic blocks 17 to prevent them from loosening and displacement. By setting the fixing plate 18, the spring 19, the support rod 20, the clamping rod 21 and the clamping block 22, , insert one end of the card rod 21 into the card slot on the card block 22, and use the card rod 21 and the card block 22 to fix the flow meter 13, so that it is firmly placed on the fixed frame 12 to prevent it from falling off. At the same time, the support rod 20 connected to the card rod 21 is supported by the spring 19, so that the support rod 20 can drive the card rod 21 to move. After separating the card rod 21 from the card block 22, the fixation of the flow meter 13 can be cancelled, so that the flow meter 13 can be removed from the fixed frame 12 for replacement, which is convenient for use.

[0026] In this embodiment, Figures 1-4 As shown, a floating plate 23 is movably mounted inside the chemical storage barrel 3. A vertical rod 24 is fixedly mounted on the top of the floating plate 23, extending through the top of the chemical storage barrel 3. An indicator plate 25 is fixedly mounted on the top of the vertical rod 24. A scale plate 26 is fixedly mounted on the top of the chemical storage barrel 3. The indicator plate 25 is movably mounted on the scale plate 26. A feed pipe 27 is fixedly mounted on the surface of the chemical storage barrel 3. One end of the feed pipe 27 is provided with a sealing cap 28 connected by a thread. The arrangement of the floating plate 23, the vertical rod 24, the indicator plate 25, and the scale plate 26 allows the residual amount of auxiliary material in the chemical storage barrel 3 to be detected. The floating plate 23 will descend as the auxiliary material decreases, and the indicator plate 25 and the scale plate 26 record the depth of the descent, allowing for timely replenishment. The arrangement of the feed pipe 27 and the sealing cap 28 facilitates the addition of auxiliary material to the chemical storage barrel 3. The threaded connection between the sealing cap 28 and the feed pipe 27 ensures a secure connection and a seal, preventing impurities from falling off and entering.

[0027] In this embodiment, if Figures 1-4 As shown, the working process of the automatic control device for adding auxiliary materials to papermaking sizing provided in this embodiment is as follows:

[0028] The interlocking control mechanism 9 includes an electric cabinet 10 which is electrically connected to the first electric pump 4, the second electric pump 6, the fixing frame 12 and the gluing valve 14. At the same time, the electric cabinet 10 is electrically connected to a controller 11 with a DCS system. When a paper break occurs in the sizing machine 1, the gluing valve 14 will be closed. At this time, the closing of the gluing valve 14 will transmit a signal to the electric cabinet 10 to issue a paper break alarm. Then the electric cabinet 10 will transmit the signal to the controller 11, so that the DCS system in the controller 11 is interlocked to shut down the first electric pump 4 and the second electric pump 6. The interlocking signal of the DCS system in the controller 11 is used to control the start and stop of the first electric pump 4 and the second electric pump 6, so that the entire process does not require human intervention, achieving full automation and greatly improving production efficiency.

[0029] In summary, in this embodiment, according to an automatic control device for adding auxiliary materials to papermaking glue according to this embodiment, by setting the slide rail 15 and the protective plate 16, the two protective plates 16 are pulled to slide on the slide rail 15 to fit together. The fitted protective plates 16 can cover the controller 11 inside, thereby protecting the controller 11 and preventing the controller 11 from being damaged by collision. By setting the magnetic block 17, the adsorption of multiple magnetic blocks 17 can be used to fix the fitted protective plates 16 to prevent them from loosening and displacement. By setting the fixing plate 18, the spring 19, the support rod 20, the clamping rod 21 and the clamping block 22, one end of the clamping rod 21 is inserted into the clamping groove on the clamping block 22. The clamping of the clamping rod 21 and the clamping block 22 can fix the flow meter 13 so that it is firmly placed on the fixed frame 12 to prevent it from falling off. At the same time, the support rod 20 connected to the card rod 21 is supported by the spring 19, so that the support rod 20 can drive the card rod 21 to move. After the card rod 21 is separated from the card block 22, the fixation of the flow meter 13 can be cancelled, so that the flow meter 13 can be removed from the fixed frame 12 for replacement, which is convenient for use. Through the arrangement of the floating plate 23, the vertical rod 24, the indicator plate 25 and the scale plate 26, the remaining auxiliary material in the chemical storage barrel 3 can be detected. The floating plate 23 will drop together with the reduction of the auxiliary material, and the indicator plate 25 and the scale plate 26 will record the depth of the drop so that it can be replenished in time. Through the arrangement of the feeding pipe 27 and the sealing cover 28, it is convenient to add auxiliary materials to the chemical storage barrel 3. The sealing cover 28 and the feeding pipe 27 are threadedly connected so that they can be firmly connected and sealed to prevent impurities from falling off and entering.
