[0068] Optionally, the ton bag hoisting system 3 comprises a hoisting support 301, an electric hoist 302, a starch ton bag 305, a sliding rail 303 and a hoisting hook 304; the hoisting support 301 is arranged between the clean water tank 1 and the starch preparation tank 5 and is fixedly connected to the ground; the top end of the hoisting support 301 is provided with the sliding rail 303, which is fixedly connected to the hoisting support 301; the electric hoist 302 is arranged on the sliding rail 303 and is rollingly connected to the sliding rail 303; the electric hoist 302 is electrically connected to the control system 7; the hoisting hook 304 is connected below the electric hoist 302; and the hoisting hook 304 hooks the starch ton bag 305.

[0069] The working principle and beneficial effects of the above technical solution are as follows: After the starch ton bag 305 is taken out of the warehouse to the production workshop, the ton bag hoisting system 3 is used to hoist the starch ton bag 305 to the quantitative adding system 4, the starch in the starch ton bag 305 enters the starch preparation tank 5 through the quantitative adding system 4, mixes with water at a fixed ratio to form a starch solution, and is conveyed into the mixing machine by the starch water pump 6. The present application adds starch to the starch preparation tank 5 through the starch quantitative adding system 4 to make a starch solution with water, and the metering accuracy is higher compared with simply adding dry starch powder.

[0070] The system of the present application comprises two subsystems:

[0071] 1. Starch preparation system. The difference between the high and low levels of the clean water tank 1 is 20 cm, when the water level in the clean water tank 1 is lower than the low level, the level gauge two 102 responds, the control system 7 controls the pneumatic valve 8 to open, and the municipal water performs water replenishment operation, when the water level in the clean water tank 1 is higher than the high level, the level gauge one 101 responds, the control system 7 controls the pneumatic valve 8 to close, and the municipal water stops water replenishment operation; the purpose is to keep the water pressure as small as possible, so as to ensure the stability of the water flow. The clean water is automatically adjusted in frequency by the first flow meter 201 after passing through the starch water pump 2, so as to ensure that the clean water can enter the starch preparation tank 5 at a stable flow. At the same time, the quantitative adding system 4 proportionally delivers the starch to the starch preparation tank 4 according to the set water flow, so as to complete the whole preparation process of the starch solution.

[0072] 2、Starch using system. The starch solution prepared in the starch preparation tank 5 enters the mixer through the starch outlet pump 6 and the second flow meter 601. Only the flow of the second flow meter 601 needs to be set during production, and the frequency adjustment of the starch outlet pump 6 is automatically fed back. When the production specification changes and the starch dosage needs to be increased, only the corresponding frequency of the starch outlet pump 6 needs to be increased, so as to increase the addition concentration of starch in the gypsum board.

[0073] The system can effectively realize the wet addition of starch in the gypsum board production process, such as the starch solution addition mode, stable production, and improved product quality.

[0074] The present application solves the technical problems of existing dry starch addition methods, in which the starch exists in a solid state, and the starch and plaster powder will be mixed unevenly after being added, thereby causing various product quality problems.

[0085] The main function of the present application is to realize the wet method addition in the gypsum board production process after the dry powder starch is configured into a water agent.

[0086] The working principle of the above technical solution is as follows: the ton bag unloading device 9 works together with the ton bag hoisting system 3 and the quantitative adding system 4, the starch ton bag 305 is hoisted to a specified height by the electric hoist 302 and the hoisting hook 304 of the ton bag hoisting system 3, the control system 7 controls the electric hoist 302 to move along the slide rail 303 to a specified area above the ton bag unloading device 9, the working cable of the electric hoist 302 is lowered to drive the starch ton bag 305 to a position above the feed hopper 401 of the quantitative adding system 4, a worker unfastens the unloading port of the starch ton bag 305, since the starch is a solid powder, the unloading port is easily blocked under the action of gravity, at this time, the ton bag unloading device 9 works to perform a beating action, so that the starch ton bag 305 is smoothly unloaded, the four unloading groups are distributed in pairs in diagonal lines in the unloading support 901, when working, the unloading groups on the main diagonal line perform a beating action, the unloading groups on the auxiliary diagonal line keep the state of the last beating action for a short time to stably hold the ton bag without shaking, and then the unloading groups on the main and auxiliary diagonal lines alternately perform a beating action to form a continuous beating until the starch is unloaded, through the above unloading of the unloading groups, the unloading of the starch ton bag 305 can be accelerated, and the starch unloading efficiency is improved.

[0087] Specifically, when the starch ton bag 305 is unloaded, the control system 7 controls the different rotating speeds of the servo motor 902 of the unloading group in the ton bag unloading device 9, the servo motor 902 drives the unloading cam 903 to rotate, the unloading cam 903 abuts against the unloading push rod 908 to reciprocally slide along the support plate 917, and the unloading disc 909 at the end of the unloading push rod 908 performs a beating action, under the action of gravity and beating force, the starch falls from the starch ton bag 305 into the feed hopper 401, and the electric hoist 302 lifts the empty ton bag away after the unloading of the starch ton bag 305 is completed.
