[0023] The present invention provides a weighing mechanism, which comprises a supporting tray, a weighing module, a rotating disk and a rotating drive module; the weighing pan of the weighing module is located in the supporting tray, and the weighing modules are provided in plurality, and the plurality of weighing modules are sequentially distributed along the circumference of the supporting tray; the rotating disk is rotatably provided, and the rotating disk is located above the supporting tray, so as to drive the material receiving container on the supporting tray to move; a through hole is provided on the rotating disk corresponding to the weighing pan, and the through hole penetrates the rotating disk in the height direction, so as to accommodate the material receiving container, and the aperture of the through hole is larger than the material receiving container; the through holes are provided in plurality, and the plurality of through holes are sequentially distributed along the circumference of the rotating disk, and correspond to the weighing modules; the rotating drive module is connected to the rotating disk, so as to drive the rotating disk to rotate. The weighing mechanism is provided with a plurality of weighing modules, so that a plurality of receiving containers can be weighed at the same time, which can improve the weighing efficiency, and the weighing mechanism relies on the circular rotation of the rotating disk to drive the receiving container to move, which can make the overall structure layout more compact, and can be conducive to the arrangement and docking of the upstream and downstream process equipment of the entire production line. In addition, the aperture of the through hole opened on the rotating disk is larger than the receiving container, so that when the rotating disk drives the receiving container to move into place, the rotating disk is retreated to a certain position, so that the hole wall of the through hole can be separated from the receiving container, and the rotating disk can be prevented from contacting the receiving container during weighing, and the rotating disk will not interfere with the weighing of the receiving container, thereby improving the accuracy of weighing.

[0024] Please refer to Figures 1 to 8 In one embodiment, a weighing mechanism 100 is provided, which is used to weigh the receiving container 200 after filling and mixing.

[0025] The weighing mechanism 100 includes a supporting tray 10, a weighing module 20, a rotating disk 30 and a rotating drive module 40. The supporting tray 10 is mainly used to support the material receiving container 200, the weighing module 20 is mainly used to weigh the material receiving container 200, the rotating disk 30 is mainly used to drive the material receiving container 200 to move, and the rotating drive module 40 is mainly used to drive the rotating disk 30 to rotate.

[0026] The weighing pan 21 of the weighing module 20 is located in the tray 10, and the weighing module 20 is provided in plurality, and the plurality of weighing modules 20 are sequentially distributed along the circumference of the tray 10. Since the weighing modules 20 are provided in plurality and sequentially distributed along the circumference, the plurality of receiving containers 200 can be weighed synchronously by the plurality of weighing modules 20, thereby improving the weighing efficiency.

[0027] The rotating disk 30 is rotatably arranged, and the rotating disk 30 is located above the receiving tray 10, so as to drive the receiving container 200 on the receiving tray 10 to move. A through hole 31 is provided on the rotating disk 30 at a position corresponding to the weighing pan 21, and the through hole 31 penetrates the rotating disk 30 in the height direction, and the through hole 31 is used to accommodate the receiving container 200. In other words, the receiving container 200 is accommodated in the rotating disk 30 through the through hole 31, and when the rotating disk 30 rotates, the receiving container 200 is contacted through the hole wall of the through hole 31, thereby driving the receiving container 200 to move. The aperture of the through hole 31 is larger than that of the material receiving container 200. Since the aperture of the through hole 31 is larger than that of the material receiving container 200, after the rotating disk 30 drives the material receiving container 200 to move into position, the rotating disk 30 can be retracted a certain distance, so that the material receiving container 200 and the hole wall of the through hole 31 are spaced apart from each other, so that the material receiving container 200 does not contact the rotating disk 30, thereby improving the accuracy of weighing. The aperture of the through hole 31 being larger than that of the material receiving container 200 means that the aperture of the through hole 31 is larger than that of the material receiving container 200. For example, Figure 5As shown, the receiving container 200 is divided into a top portion 210, a middle portion 220 and a bottom portion 230 from top to bottom. When the receiving container 200 is fed into the weighing mechanism 100, the middle portion 220 is located in the through hole 31, and the diameter of the through hole 31 is larger than the diameter of the middle portion 220. In addition, in some embodiments, in order to facilitate the placement of the receiving container 200 into the weighing mechanism 100, the diameter of the bottom portion 230 may also be smaller than the through hole 31, so that when the receiving container 200 is placed into the weighing mechanism 100, the receiving container 200 can be directly inserted into the rotating disk 30 from above and placed on the supporting tray 10.

[0028] There are a plurality of through holes 31, which are sequentially distributed along the circumference of the rotating disk 30 and correspond to the weighing modules 20. That is, the distribution positions of the plurality of through holes 31 correspond to the distribution positions of the plurality of weighing modules 20, so that during weighing, a plurality of receiving containers 200 can be placed in the weighing mechanism 100, and the rotating disk 30 can drive the plurality of receiving containers 200 to move synchronously, and the synchronous weighing measurement of the plurality of receiving containers 200 can be performed at one time.

[0029] The rotation driving module 40 is connected to the rotating disk 30 to drive the rotating disk 30 to rotate.

[0030] It is understandable that most of the prior art uses linear movement to transfer the receiving material container. In order to improve the weighing efficiency, it is necessary to weigh multiple receiving material containers simultaneously. Therefore, multiple weighing modules need to be arranged in the weighing mechanism. Since the prior art uses linear movement to transfer the receiving material container, the more weighing modules that are compatible with the weighing mechanism, the longer the entire production line will be, which is not convenient for post-process operations after weighing is completed, and is not conducive to the layout of upstream and downstream equipment. It is precisely because of this limitation that the number of weighing modules that can be arranged in the weighing mechanism of the prior art is limited, which limits the improvement of the weighing efficiency of the existing weighing mechanism.

[0031] In the weighing mechanism 100 provided in the present embodiment, the circular rotation of the rotating disk 30 drives the receiving container 200 to move, and drives the receiving container 200 to be transmitted in the form of circular arc movement, so that the overall structure can be more compact, which is conducive to the arrangement and docking of upstream and downstream equipment and process equipment. At the same time, it also makes it possible to arrange more weighing modules 20, which can further improve the weighing efficiency. In addition, the aperture of the through hole 31 is also larger than the receiving container 200, so that when the rotating disk 30 drives the receiving container 200 into place, the rotating disk 30 can retreat and separate from the receiving container 200, thereby avoiding the rotating disk 30 from affecting the weighing of the receiving container 200 and improving the accuracy of weighing.

[0032] In one embodiment, the operating principle of the weighing mechanism 100 is as follows: the material receiving container 200 is passed through the through hole 31 and placed on the supporting tray 10 (the material receiving container 200 can be placed by a robot), and then the rotation drive module 40 drives the rotating disk 30 to rotate, and through the rotation of the rotating disk 30, the inner wall of the through hole 31 contacts the outer wall of the material receiving container 200, thereby driving the material receiving container 200 to move. When the material receiving container 200 is driven to move to the center of the weighing pan 21, the rotation drive module 40 drives the rotating disk 30 to rotate in the opposite direction by a certain angle, thereby separating the inner wall of the through hole 31 from the outer wall of the material receiving container 200, thereby improving the accuracy of weighing.

[0033] In one embodiment, the weighing module 20 adopts an industrial-grade electronic scale, and the weighing module 20 has an accuracy of ±0.00001g and a weighing accuracy of ±0.00005g.

[0034] Preferably, in one embodiment, the center of the rotating disk 30 and the center of the receiving tray 10 are located on the same straight line, and the distances between the through holes 31 on the rotating disk 30 and the center of the rotating disk 30 are equal, and the distances between the scale pans 21 in the receiving tray 10 and the center of the receiving tray 10 are equal. Therefore, after the rotating disk 30 rotates one circle, one through hole 31 can flow through each scale pan 21 in turn. In other words, after one receiving container 200 is driven by the rotating disk 30 to rotate one circle, the receiving container 200 can flow through each scale pan 21 in turn, so that operations such as batching and filling can be facilitated.

[0035] Preferably, in one embodiment, along the circumference of the rotating disk 30, the through hole 31 includes a first hole body 311 located at one end and a second hole body 312 located at the other end, the first hole body 311 and the second hole body 312 are connected to each other, and the aperture of the first hole body 311 matches the material receiving container 200, and the aperture of the second hole body 312 is larger than the material receiving container 200. The aperture of the first hole body 311 matches the material receiving container 200, which means that the aperture of the first hole body 311 matches the portion of the material receiving container 200 located in the through hole 31. For example, the aperture of the first hole body 311 may be equal to the diameter of the middle portion 220, so that when the material receiving container 200 is located in the first hole body 311, the hole wall of the first hole body 311 may fit on one side of the middle portion 220. That is to say, in this embodiment, the through hole 31 extends along the circumferential direction for a certain length, and the through hole 31 is a structure with one end larger than the other end. This structure can facilitate the rotation disk 30 to drive the receiving container 200 to move, and can also facilitate the separation of the rotation disk 30 from the receiving container 200 during weighing. It can be understood that when the rotation disk 30 is required to drive the receiving container 200 to move, the hole wall of the first hole body 311 is attached to one side of the receiving container 200, so that the receiving container 200 is driven to move through the hole wall of the first hole body 311, and the aperture of the first hole body 311 matches the receiving container 200, so that the hole wall of the first hole body 311 can be more perfectly attached to one side of the receiving container 200, and the receiving container 200 will not deviate radially during the movement, which can ensure that the receiving container 200 moves to the center of the weighing pan 21, thereby improving the accuracy of subsequent weighing. After being moved into position, the rotating disk 30 rotates in the opposite direction by a certain angle, so that the receiving container 200 is located in the second hole 312 or in the area between the second hole 312 and the first hole 311, so that the hole wall of the through hole 31 is separated from the receiving container 200.

[0036] More preferably, in one embodiment, in the through hole 31, the aperture of the through hole 31 gradually expands from the first hole 311 to the second hole 312. That is, in this embodiment, the aperture of the through hole 31 gradually changes along the circumferential direction, so as to facilitate the placement of the material receiving container 200 and facilitate the contact and separation between the rotating disk 30 and the material receiving container 200.

[0037] Preferably, in one embodiment, the through holes 31 on the rotating disk 30 are evenly spaced and distributed in the rotating disk 30 along the circumference, and the number of the through holes 31 is greater than the number of the weighing modules 20. This structure can facilitate the loading and unloading of the receiving container 200. For example, in one embodiment, 16 through holes 31 are provided on the rotating disk 30, and 15 weighing modules 20 are provided, that is, in the entire circumference, there is an area where the weighing modules 20 are not arranged, and this area can be used as a loading and unloading station. When the through holes 31 flow to this area, the loading and unloading of the receiving container 200 can be performed by the manipulator.

[0038] Preferably, in one embodiment, the top surface 11 of the tray 10 is provided with a step 12, and the step 12 is located at the front side of the weighing pan 21 of the weighing module 20, wherein the "front side" is based on the direction in which the receiving container 200 moves on the tray 10, that is, when the rotating disk 30 drives the receiving container 200 to move, the receiving container 200 will first flow through the step 12, and then flow through the weighing pan 21 corresponding to the step 12. Along the circumference of the rotating disk 30, the height of the step 12 changes gradually, and the height of the step 12 on the side close to the weighing pan 21 is higher than the height on the side away from the weighing pan 21. That is, when the receiving container 200 flows through the step 12, the height of the receiving container 200 will be gradually raised, and then fall into the weighing pan 21. In this embodiment, the weighing pan 21 can be better protected by the provision of the step 12. It is understandable that industrial-grade electronic scales are more accurate and more sensitive to impacts. When the weighing module 20 is installed, if there is an installation error, resulting in the weighing pan 21 protruding from a portion of the top surface 11, the receiving container 200 is likely to hit the weighing pan 21 when moving on the tray 10. By setting the step 12, when the receiving container 200 moves and is about to contact the weighing pan 21, the receiving container 200 can be lifted to a certain height to avoid the receiving container 200 hitting the weighing pan 21 of the weighing module 20.

[0039] More preferably, in one embodiment, a step 12 is correspondingly provided on the front side of the weighing pan 21 of each weighing module 20 .

[0040] More preferably, in one embodiment, the height of the step 12 away from the side of the weighing pan 21 is flush with the top surface 11 , so that the receiving container 200 can be moved onto the step 12 more smoothly.

[0041] Preferably, in one embodiment, the support tray 10 is provided with an avoidance hole 13, the avoidance hole 13 penetrates the support tray 10 in the height direction, and the weighing pan 21 of each weighing module 20 is correspondingly located at one of the avoidance holes 13. That is, in this embodiment, the support tray 10 is provided with a plurality of hole structures, and the weighing pan 21 is correspondingly arranged in these hole structures.

[0042] More preferably, in one embodiment, the top surface 11 of the tray 10 is horizontally arranged, and the top surface of the weighing pan 21 is flush with the top surface 11 of the tray 10. With this structure, the weighing level can be ensured and the weighing accuracy can be improved.

[0043] Preferably, in one embodiment, the rotating disk 30 is parallel to the supporting tray 10 , and the rotating disk 30 is parallel to each of the weighing pans 21 .

[0044] Specifically, in one embodiment, the weighing module 20 is installed at the bottom of the supporting tray 10 .

[0045] Preferably, in one embodiment, the rotation drive module 40 includes a stepper motor and a transmission unit, the output shaft of the stepper motor is connected to the transmission unit, and the transmission unit is connected to the rotating disk 30. Specifically, in one embodiment, the transmission unit can adopt a belt transmission structure, and drive the rotating disk 30 to rotate through a pulley. The stepper motor can perform high-precision positioning circular rotation motion, and the gear belt and other components can perform different ratios of speed change to achieve the required speed.

[0046] Meanwhile, in one embodiment, a batching weighing device 1000 is also provided, which includes a silo 300 and the weighing mechanism 100, wherein the silo 300 is located above the rotating disk 30, and the discharge port of the silo 300 is arranged corresponding to the through hole 31. That is, when the rotating disk 30 drives the receiving container 200 to move, the receiving container 200 can be moved to below the discharge port of the silo 300, so that the material can be poured into the receiving container 200 through the silo 300.

[0047] The silo 300 is a container for storing powders and liquids before weighing, and the receiving container 200 is a container for holding materials used in the process of mixing powders, liquids, or powders and liquids.

[0048] Preferably, in one embodiment, the batching weighing device 1000 further includes a silo mounting plate 400, the silo 300 is arranged on the silo mounting plate 400, and the silo 300 is provided in plurality, and the plurality of silos 300 are sequentially distributed along the circumference of the silo mounting plate 400. More preferably, the silos 300 are arranged in a one-to-one correspondence with the weighing modules 20. Among them, the plurality of silos 300 include a powder silo 310 and a liquid silo 320, the powder silo 310 is mainly used to store powder materials, and the liquid silo 320 is mainly used to store liquid materials.

[0049] Preferably, in one embodiment, the discharge port of the silo 300 is located above the weighing pan 21. More preferably, in one embodiment, the discharge port of the silo 300 is located just above the center of the weighing pan 21, so as to better ensure the accuracy of weighing.

[0050] It is understandable that some weighing equipment in the prior art also uses circular motion for weighing, but in the prior art, multiple silos can only be matched with one weighing module. During operation, the silos move while the weighing module does not move. This is relatively inefficient and cannot meet the needs of high-efficiency production.

[0051] The batching weighing device 1000 provided in this embodiment drives the receiving container 200 to move through the rotating disk 30, while the weighing module 20 and the silo 300 do not move. In addition, a plurality of weighing modules 20 and a plurality of silos 300 are provided, thereby further improving the efficiency of batching weighing.

[0052] Preferably, in one embodiment, the batching weighing equipment 1000 has a material loading and unloading station 1001 and a plurality of the batching weighing stations 1002, the material loading and unloading station 1001 and the plurality of the batching weighing stations 1002 are evenly spaced in sequence along the circumferential direction, and each of the batching weighing stations 1002 is correspondingly provided with a material bin 300 and a weighing module 20. When the batching weighing equipment 1000 is in operation, the empty material receiving container 200 is inserted from the material loading and unloading station 1001 into the through hole 31 by a manipulator, and is placed on the supporting tray 10, and then the material receiving container 200 is driven to move to the batching weighing station 1002 by the rotation of the rotating disk 30, and the rotating disk 30 is then rotated a certain angle, and then the material bin 300 is unloaded, and the weighing module 20 is weighed. When the rotating disk 30 drives the receiving container 200 to rotate back to the loading and unloading station 1001, the receiving container 200 with the batching completed is taken out by the manipulator. The materials in each of the silos 300 can be different. During the batching weighing process, the system can unload materials according to demand. For example, when the receiving container 200 needs to be configured with materials in the batching weighing stations 1002 No. 1 and No. 4, the corresponding silos 300 will unload materials only when the receiving container 200 moves to the batching weighing stations 1002 No. 1 and No. 4, and when it moves to other batching weighing stations 1002, other silos 300 will not unload materials. Through this structure, different materials can be configured according to demand, which greatly improves the efficiency of batching weighing.

[0053] For example, in one embodiment, the batching weighing equipment 1000 has 16 workstations, and the 16 workstations are evenly spaced in sequence along the circumference, of which 15 workstations are batching weighing workstations 1002 and 1 workstation is a material loading and unloading workstation 1001.

[0054] It is understandable that in order to improve the weighing precision and accuracy, the receiving container should be accurately moved to the center of the weighing module during weighing, without interfering with the weighing (when the weighing module is weighing, the receiving container can only touch the weighing module scale plate). In addition, the high-precision weighing process has high requirements for the horizontality and stability of the weighing module, which must be fixed horizontally and not disturbed by external forces.

[0055] The batching weighing equipment 1000 can simultaneously distribute 15 weighing modules 20 on a 360° disc. The weighing modules 20 are fixed to ensure that they are level during weighing and are not disturbed by external forces. The receiving container 200 is driven by a stepper motor to make circular motion on the 360° disc, and can accurately move to the center of the weighing module 20, and then retreat, so as to achieve the purpose of not contacting the receiving container 20 with the surroundings during weighing, thereby improving the precision and accuracy of weighing. 15 stations are weighed at the same time, and the 15 weighing modules 20 do not interfere with each other, so that multiple stations can batch ingredients at the same time. And the weighing process relies on the weight feedback from the high-precision weighing module, real-time detection, and increasing the weight in sequence, so as to achieve the required accuracy.

[0056] The batching weighing equipment 1000 can be applied to all powder batching, liquid batching, powder and liquid mixed batching, and the materials stored in the silo 300 can be selected according to different batching requirements. The weighing module 20 is fixed on the fixed plane of the equipment; the supporting tray 10 of the moving reference plane of the receiving container 200 is fixed on the fixed plane of the equipment; the stepping motor of the rotating drive module 40 is fixed on the fixed plane of the equipment, and the suspended rotating disk 30 is driven to rotate through the pulley; the receiving container 200 is driven by the clockwise rotation of the rotating disk 30, and after the receiving container 200 is driven to the center of the weighing pan 21, the rotating disk 30 rotates counterclockwise, and the empty space of the through hole 31 prevents the receiving container 200 and the rotating disk 30 from contacting the batching.

[0057] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
