Here, the belt scale is composed of a conveyor belt 4, a load cell 2, and a drive motor 3. Wherein the content of the first and second substances,

the conveyor belt 4 is used for conveying pulp, and the pulp is conveyed to a material using device 6 through the conveyor belt 4.

The weighing sensor 2 is used for measuring the weight of the sizing agent on the conveying belt 4 and converting the detected mass signal into an electric signal to be sent out. Specifically, the weighing sensor 2 may be a bearing plate or a bearing roller disposed below the upper belt surface of the conveyor belt 4, so that when slurry falls on the upper belt surface of the conveyor belt 4, the bearing plate or the bearing roller directly weighs the slurry, thereby outputting an electrical signal; the load cell 2 may also be a bench scale positioned below the conveyor belt 4 so that, in use, the weight of the slurry may be determined by measuring the change in weight of the conveyor belt 4, thereby outputting an electrical signal.

The load cell 2 outputs an electric signal to the drive motor 3 and the pump 11. The driving motor 3 is used for driving the conveying belt 4 to rotate, when the driving motor 3 receives an electric signal, the driving motor 3 rotates, and the conveying belt 4 conveys materials to the material using equipment 6. The water adding device 1 is used for packaging a water tank, a pump 11 and a water pipe, and when the pump 11 receives an electric signal, the pump 11 works to convey water in the water tank to the material using equipment 6 through the water pipe.

The embodiment of the utility model provides an automatic material conveying device is when in actual use, as shown in fig. 2, belt weigher's conveyer belt 4's upper band face below sets up plate-type weighing plate (promptly weighing sensor 2), plate-type weighing plate gives the belt weigher instrument with weighing signal transmission, and the belt weigher instrument passes through RS485/422 and is connected with interface board, industrial computer and PLC controller in proper order (promptly switch board 9), the PLC controller pass through the controller respectively with driving motor 3 with pump 11 connects.

Therefore, when the slurry feeding device is used, slurry is conveyed to the conveying belt 4, the weighing sensor 2 senses and records the weight of the slurry, when the adding amount of the slurry reaches a preset weight, the weighing sensor 2 can directly or through a PLC (programmable logic controller) to send signals to the driving motor 3 and the pump 11, at the moment, the conveying belt 4 rotates under the action of the driving motor 3, the slurry is further conveyed into the stirring machine, the pump 11 on the water adding device 1 works to convey water into the stirring machine, it needs to be noted that the adding amount of the water can be adjusted according to needs, when the adding amount of the water meets requirements, the pump 11 can be closed in a manual closing or automatic closing mode, so that one-time filling is completed, and when the filling is needed again, the steps are repeated.

Furthermore, in order to adjust the pump 11 and limit the flow rate of the water from the water adding device 1, the time relay is provided on the pump 11 of the water adding device 1, specifically, when the water adding device is installed, the coil of the relay of the pump is controlled by the contact of the time relay, so as to realize the time delay control, and the flow control valve is provided on the water outlet pipe of the water adding device 1.

Simultaneously, can also set up the time delay funnel that divides on water adding device 1's the outlet pipe, when using, the time delay funnel that divides has the water storage function, after according to the proportion water storage, can postpone water and carry in the consumer 6, when having avoided directly sending into consumer 6 with water and thick liquids like this and stirring, the difficult problem of stirring.

Furthermore, a material blending belt 51 is arranged at the discharge end of the conveying belt 4, and an adjustable baffle plate 52 is arranged on the material blending belt 51. When continuous operation is carried out like this, refining belt 51 sets up between conveyer belt 4 and material equipment 6, can avoid appearing the problem of long-pending material on the conveyer belt 4, adjustable baffle 52 can adjust, works as adjustable baffle 52 is in the state of erectting, and the material can't be followed pass through on the conveyer belt 4, works as when adjustable baffle 52 is in the open mode, the material is followed pass through on the conveyer belt 4 and get into all in the material equipment 6.

Further, in the embodiment of the present invention, the conveyer belt 4 is provided with a hopper 41, and the conveyer belt 5 is arranged above the hopper 41.

Grid mesh plates for buffering falling impact force of materials are arranged in the hopper 41.

Here, in order to facilitate stable conveying of the slurry to the conveying belt 4, the phenomenon that the material conveyed on the conveying belt 5 may overflow to the outside of the conveying belt 4 when being conveyed is avoided, so the conveying belt 4 is provided with the hopper 41, the hopper 41 is detachably installed on the conveying belt 4, when the conveying belt is used, the hopper 41 can be fixed on the conveying belt 4, and the hopper 41 is internally detachably provided with a grid mesh plate for buffering falling impact force of the material, so that the slurry falls to the feeding end of the conveying belt 4 through the hopper 41 and is conveyed, and the phenomenon that the slurry directly falls to the conveying belt 4 is avoided, so that the impact on the conveying belt 4 is too large, and the measurement value of the weighing sensor 2 is greatly deviated. Specifically, the size of the opening on the grid plate is larger than 15cm × 20 cm. More specifically, the grid plates can also be mounted on the conveyor belt 5, so that the influence on the actual weighing of the accurate weight on the conveyor belt 4 when slurry falls on the grid plates is avoided.
