[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 In this embodiment of the present invention, a quantitative packaging device for water-reducing agent includes a filling mechanism and a weighing mechanism. The filling mechanism includes a filling tank 1, and the weighing mechanism includes an end plate 2. The filling tank 1 is installed above a support plate 11 and extends to the bottom of the support plate 11. A drive mechanism extending to the bottom of the support plate 11 is installed at the top of the support plate 11. A clamping plate 10 is connected to the output end of the drive mechanism. A rotary motor 3 is installed at the top of the filling tank 1. A spiral conveying rod 4 extending to the inner cavity of the discharge port of the filling tank 1 is connected to the output end of the rotary motor 3. Two transmission rollers 13 are rotatably installed on the inner side of the end plate 2. The two transmission rollers 13 tension the transmission belt 15. A rotary motor 14 is installed at one end of one end plate 2. The output end of the rotary motor 14 is coaxially fixedly connected to one transmission roller 13. Multiple support rollers 16 supporting the upper part of the transmission belt 15 are rotatably installed on the inner side of the two end plates 2. A bracket mechanism is installed at the bottom end of the end plate 2.

[0020] In this embodiment: First, the opening of the packaging bag is placed at the outlet of the filling tank 1. Then, the drive mechanism is started, which drives the two clamping plates 10 to clamp the opening of the packaging bag. Then, the rotating motor 3 is started, which drives the spiral conveyor rod 4 to rotate. The rotating spiral conveyor rod 4 feeds the powdered water-reducing agent into the packaging bag. At this time, the bottom of the packaging bag contacts the top of the weighing mechanism, and the water-reducing agent in the packaging bag is weighed in real time. After the packaging weight is reached, the Wheatstone circuit of the weighing mechanism sends an electrical signal to the controller to control the rotating motor 3 to stop running and stop continuous feeding. At the same time, the controller controls the weighing mechanism to drive the quantitatively packaged packaging bag to be conveyed.

[0021] Please refer to this carefully. Figure 2The drive mechanism includes an electric push cylinder 5 fixedly installed at the bottom of the support plate 11. The piston rod of the electric push cylinder 5 extends through the top of the support plate 11. The two support plates 11 are electrically connected to the controller through a synchronizer. The top of the two support plates 11 is fixedly connected to the bottom of a lifting ring 6. A double-sided rack 7 is welded to the bottom of the lifting ring 6, extending through the bottom of the support plate 11. A gear 8 is rotatably installed at the bottom of the support plate 11 through a fixed lug. A double-sided rack 7 meshes with two gears 8. A rotating arm 9 is fixedly installed at the center of one end of the two gears 8. The rotating arm 9 is fixedly connected to a clamping plate 10 for clamping the packaging bag.

[0022] In this embodiment: when clamping the opening of the packaging bag, the controller sends the same command (e.g., extension command) to the synchronizer. The synchronizer obtains the current state (e.g., position, speed) of the two electric push cylinders 5. If there is a deviation between the two, the synchronizer calculates the compensation value and adjusts the output signal to achieve the purpose of synchronous operation of the two electric push cylinders 5.

[0023] The two electric push cylinders 5 in the extended state push the lifting ring 6 to move upward. The lifting ring 6 drives the two double-sided racks 7 to move upward. One double-sided rack 7 drives the two gears 8 meshing with it to rotate in opposite directions. At this time, the two rotating arms 9 rotating in opposite directions drive the clamping plate 10 to clamp the opening of the packaging bag.

[0024] Conversely, when the two electric push cylinders 5 shorten, the clamping on the opening of the packaging bag can be released.

[0025] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 The support mechanism includes a base plate 19 in contact with the ground. Adjustment components are fixedly installed at the four corners of the top of the base plate 19. A level plate 18 is fixedly installed at the top of the adjustment components. Pressure sensors 17 are fixedly installed at the four corners of the top of the level plate 18. The Wheatstone circuit composed of four pressure sensors 17 is electrically connected to the rotary motor 14 through a controller. The four corners of the bottom of the end plate 2 are in contact with the top of the pressure sensors 17. A downwardly protruding guide rod is integrally formed at the bottom of the end plate 2. A guide hole for the guide rod to slide vertically is opened inside the level plate 18. A bubble level 22 is installed on the top of both the long side and the wide side of the level plate 18.

[0026] In this embodiment: when the weight of the powdered water-reducing agent is applied to the top of the transmission belt 15 through the packaging bag and supported by the support roller 16, the overall weight is applied to the pressure sensor 17 through the end plate 2. When the pressure reaches the preset value, the Wheatstone bridge composed of the four pressure sensors 17 sends an electrical signal to the controller. The controller controls the rotary motor 14 to run, and the rotary motor 14 can drive the transmission belt 15 to transport the packaging bag through the transmission roller 13.

[0027] Please refer to this carefully. Figure 4 and Figure 5 The adjustment assembly includes a lower adjustment rod 21 that is movably mounted on the top of the base plate 19 via a ball joint. The inner wall of the lower adjustment rod 21 is threaded with an adjustment screw 12 that extends through to the top of the lower adjustment rod 21. An upper adjustment rod 20 is rotatably mounted on the outer wall of the top of the adjustment screw 12. The upper adjustment rod 20 is movably connected to the bottom of the horizontal plate 18 via a universal joint. A hexagonal head 23 is fixedly mounted on the outer wall of the adjustment screw 12 below the upper adjustment rod 20.

[0028] In this embodiment: when the installation ground is uneven, the position of the bubbles in the two bubble levels 22 is observed to determine the tilt angle of the horizontal plate 18. At this time, a wrench is used to connect with the corresponding tilted hexagonal head 23 and rotate the hexagonal head 23. The hexagonal head 23 drives the corresponding adjusting screw 12 to rotate. At this time, the lower adjusting rod 21 cannot rotate, so the adjusting screw 12 can only be turned upwards or downwards. Therefore, rotating different hexagonal heads 23 can adjust the levelness of the horizontal plate 18, and the levelness of the horizontal plate 18 after adjustment can be observed through the two bubble levels 22.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
