Since the feeding hopper 36 in the feeding assembly is provided with a plurality of feeding hoppers, different types or properties of materials can be placed in the feeding hoppers, or the same type or shape of material can be placed in the feeding hoppers. After the material to be weighed is poured into the feeding hopper 36, the rotating frame 4 is driven to rotate, the mounting plate 7 and the supporting plate 6 are synchronously rotated by the rotation of the rotating frame 4, and the feeding hopper 36 and the material placing cylinder 15 are synchronously rotated, until the corresponding feeding hopper 36 and the material placing cylinder 15 are moved to the discharging position, the rotating frame 4 is stopped and locked, at this time, the discharging slot 8 at the bottom of the corresponding feeding hopper 36 and the material placing cylinder 15 is located above the through slot 5, then the first driving member 10 is opened, the sliding frame 9 and the weighing part on the sliding frame 9 are moved to the bottom of the through slot 5, at this time, the feeding assembly is opened, the material in the corresponding feeding hopper 36 is discharged into the weighing part through the through slot 5 and the discharging slot 8, at this time, the weighing part detects the mass of the material entering the weighing part in real time, when the weight of the material approaches the set weight value, the discharging is stopped, at this time, the feeding assembly is opened, a part of the material in the corresponding material placing cylinder 15 is discharged, and the part of the material is weighed, the mass of the part of the material is equal to the difference between the mass of the material entering the weighing part and the required mass of the material, then the part of the material is poured into the weighing part, so that the weighing result is more accurate. Then the first driving member 10 is opened, the sliding frame 9 is pushed to move, until the sliding frame 9 is moved to the material taking position, the weighed material is taken out.

[0030] If different raw materials need to be weighed at the same time and the raw materials need to be mixed, different raw materials can be put into different feeding hoppers 36 (but the materials in the adjacent two material placing cylinders 15 and feeding hoppers 36 must be the same material, if only one type of material is weighed, there is no above limitation), so that different materials can be fed respectively, and finally the materials are sent into the weighing part and weighed in sequence by the arrangement of the weighing part.

[0031] As shown in the above, Figure 3 , Figure 4 The weighing part includes a first weighing sensor 12, an alarm 13 and a collection box 14, the first weighing sensor 12 is fixedly installed between the load-bearing frame 11 and the sliding frame 9, the alarm 13 is fixedly installed on the sliding frame 9, and the collection box 14 is arranged on the load-bearing frame 11.

[0032] There is a gap between the load-bearing frame 11 and the sliding frame 9, and the first weighing sensor 12 is less disturbed by the arrangement of the load-bearing frame 11 and the sliding frame 9, so that the detection accuracy is improved.

[0033] Specifically, when the material needs to be weighed, the collection box 14 is installed on the bearing frame 11 in advance, and then the sliding frame 9 is moved to the bottom of the through slot 5 through the setting of the first driving element 10, at this time the collection box 14 is moved to the bottom of the through slot 5, and then the material can be poured into the collection box 14, and the first weighing sensor 12 detects the weight of the material entering the collection box 14 in real time, and when the weight of the material approaches the set weight value, the alarm 13 is triggered, and the corresponding discharge hopper 36 stops discharging.

[0034] As shown in Figures 5 to 8 The top of the support frame 2 and the bottom of the bearing frame 3 are both provided with a through slot 5, and the two through slots 5 correspond to each other. The through slot 5 is located at the upper part of the weighing assembly. The support plate 6 and the mounting plate 7 are both fixedly installed on the rotating frame 4.

[0035] Specifically, when the material is added, the actual weight of the material in the collection box 14 is obtained through the setting of the first weighing sensor 12, so as to obtain the difference between the actual weight and the set weight. At this time, the conveying part is started, the material in the corresponding material placing cylinder 15 is taken out, and the material is discharged into the material adding weighing part through the setting of the conveying cylinder 16. Through the setting of the material adding weighing part, the material discharged through the conveying cylinder 16 is weighed in real time. When the weight of the material entering the material adding weighing part approaches the difference between the actual weight and the set weight of the material in the collection box 14, the speed of the conveying part can be controlled, so as to control the speed of discharging, until the required weight is reached, the conveying part is closed, and the weighed material is added to the collection box 14, so that the weight of the material in the collection box 14 is closer to the set weight value, thereby improving the accuracy of weighing.

[0041] As shown above, Figure 7 , Figure 9 As shown above,

[0042] Among them, there is a gap between the sliding block 30 and the protective frame 31, and through the arrangement of the sliding block 30 and the protective frame 31, the second weighing sensor 32 is less disturbed, and the detection accuracy is improved.

[0043] Specifically, when the conveying groove 21 continuously discharges material into the material hopper 28, through the arrangement of the second weighing sensor 32, the weight of the material entering the material hopper 28 can be detected in real time, when the material approaches the required weight, the discharge speed can be slowed down until the required weight is reached, then the discharge can be stopped, and then the discharge member is opened, the weighed material can be added to the collection box 14.

[0044] Among them, as shown above, Figure 7 , Figure 9 As shown above,

[0045] Specifically, when the material in the material hopper 28 is added to the collection box 14, the turnover plate 34 is driven to swing by the fourth motor 33 until the two sides of the turnover plate 34 are separated from the inner wall of the material hopper 28, at which time the material in the material hopper 28 can fall into the collection box 14, at which time the vibration motor 35 is turned on, so that the material hopper 28 vibrates, assisting the discharge of the material and reducing the possibility of the material adhering to the material hopper 28 and the turnover plate 34, improving the accuracy of the weighing result.

[0047] As shown in Figure 5 The discharge assembly is installed between the rotating frame 4 and the support plate 6 and is used for material discharge. The discharge assembly includes a discharge hopper 36 and a first motor 38. A plurality of discharge hoppers 36 are fixedly installed between the rotating frame 4 and the support plate 6. The plurality of discharge hoppers 36 are arranged at equal angles in a circumferential shape with the axis of the rotating frame 4 as the center. A discharge valve 37 is fixedly installed at the bottom of each of the plurality of discharge hoppers 36. The plurality of discharge valves 37 correspond to the plurality of discharge grooves 8 one by one. The first motor 38 is fixedly installed inside the support frame 2.

The second motor 39 is fixedly installed at the top of each of the plurality of discharge hoppers 36. The second stirring frame 40 is rotatably installed inside each of the plurality of discharge hoppers 36. The second stirring frame 40 is fixedly connected with the output end of the second motor 39.

[0048] Specifically, when the material is poured into the collection box 14, the discharge valve 37 at the bottom of the corresponding discharge hopper 36 is opened at this time, and the corresponding second motor 39 is also opened at this time, so as to drive the second stirring frame 40 to rotate, thereby assisting the discharge of the material. As the discharge of the material continuously proceeds, when the weight of the material in the collection box 14 approaches the required weight value, the alarm 13 at this time sends a signal. The discharge valve 37 is provided with a matched signal receiver. At this time, the discharge valve 37 at the corresponding position can be closed, and the weight of the material in the collection box 14 is less than the required weight. Then a certain amount of material is added to the collection box 14 until the set weight is reached.

[0049] The working principle or use process of the present application is as follows: When the material needs to be accurately weighed, the material is first poured into several discharge hoppers 36 and several material placing barrels 15. After the material to be weighed is poured into the discharge hoppers 36 and the material placing barrels 15, the second motor 39 is started to drive the second stirring frame 40 to rotate. The rotation of the rotating frame 4 drives the mounting plate 7 and the supporting plate 6 to rotate synchronously, thereby synchronously driving the discharge hoppers 36 and the material placing barrels 15 to rotate, until the corresponding discharge hoppers 36 and material placing barrels 15 are moved to the discharging position, the rotating frame 4 is stopped and locked, and at this time the discharging slot 8 at the bottom of the corresponding discharge hoppers 36 and material placing barrels 15 is located above the through slot 5.

[0050] Then the collection box 14 is moved to the collection position. The collection box 14 is first installed on the load-bearing frame 11, at this time the first driving member 10 is opened to move the sliding frame 9 to the bottom of the through slot 5, at this time the collection box 14 is moved to the bottom of the through slot 5, and the material can be poured into the collection box 14. At this time, the discharge valve 37 at the bottom of the corresponding discharge hoppers 36 is opened, and the corresponding second motor 39 is opened to drive the second stirring frame 40 to rotate, thereby assisting in discharging. As the material continuously enters the collection box 14, the first weighing sensor 12 detects the weight of the material entering the collection box 14 in real time. When the weight of the material approaches the set weight value, the alarm 13 is triggered, and the alarm 13 sends a signal. The discharge valve 37 is provided with a matching signal receiver, at this time the discharge valve 37 at the corresponding position is closed, and the weight of the material in the collection box 14 is less than the set weight.

[0051] At this time, the actual weight of the material in the collection box 14 is obtained through the setting of the first weighing sensor 12, thereby obtaining the difference between the actual weight and the set weight. At this time, the corresponding third motor 19 is opened, the third motor 19 drives the spiral conveying plate 18 to rotate, and the spiral conveying plate 18 drives the universal joint 27 to rotate, thereby driving one of the pulleys 24 to rotate. Through the setting of the transmission belt 25, the other pulley 24 can be driven to rotate at the same time, thereby driving the corresponding first stirring frame 26 to rotate, and the material in the material placing barrel 15 can be stirred, thereby reducing the possibility of material clumping. At this time, the material in the material placing barrel 15 is sent into the conveying cylinder 16 through the feeding end of the conveying cylinder 16, and then is discharged into the feeding frame 17 through the setting of the spiral conveying plate 18. At this time, the discharge block 22 is moved away from the conveying slot 21 by opening the second driving member 23, and at this time the material can be discharged into the feeding hopper 28 through the conveying slot 21. Through the setting of the second weighing sensor 32, the weight of the material entering the feeding hopper 28 can be detected in real time. When the material approaches the required weight, the discharging speed is slowed down until the required weight is reached, and then the third motor 19 is closed and the second driving member 23 is opened to push the discharge block 22 to block the conveying slot 21, thereby stopping the discharging.

[0052] Then the weighed material is added into the collecting box 14, at this time the fourth motor 33 is started to drive the turnover plate 34 to swing until the two sides of the turnover plate 34 are separated from the inner wall of the material adding hopper 28, then the fourth motor 33 is closed and locked, at this time the material in the material adding hopper 28 can fall into the collecting box 14, at the same time the vibration motor 35 is started to vibrate the material adding hopper 28, which can assist the material to be discharged, reduce the possibility of the material adhering to the material adding hopper 28 and the turnover plate 34, and improve the accuracy of the weighing result, then the first driving member 10 is started again to move the sliding frame 9 until the sliding frame 9 is moved to the material taking position, then the weighed material can be taken out.
