DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0028] In combination Figures 1-6 As shown, the automatic quantitative filling machine comprises:

[0029] The mounting seat 1 is arranged in a rectangular structure and is provided with wheels at the bottom of four sides, which are universal wheels, and the whole filling machine is transferred by this structure. A circular mounting plate 11 is further arranged at the top of the mounting seat 1.

[0030] The water storage tank 2 is arranged at the center of the top surface of the mounting plate 11 and is locked and fixed by bolts. A water inlet pipe is further arranged at the top of the tank body to connect external equipment, so that the staff can supplement the liquid.

[0031] The rotating disc 13 is arranged in a ring structure and is rotatably mounted at the top periphery of the mounting seat 1 by a ball bearing, and can rotate independently. A plurality of mounting grooves 14 are arranged around the top surface edge.

[0032] The weighing assembly 3 is arranged in multiple and sequentially installed in the installation slots 14, so as to cooperate with the water storage tank 2 to pre-weigh the liquid.

[0033] The conveying belt 4 is arranged with a large number of plastic bottles or other material containers on the top, so as to weigh the liquid.

[0034] Specifically, in the embodiment, the water storage tank 2 is arranged in a rectangular shape and is horizontally arranged with the water conveying pipes 21 on two opposite side walls, and the end of the water conveying pipe 21 is provided with a downwardly arranged drain pipe 22, so that the liquid in the water storage tank 2 can be discharged through the two water conveying pipes 21 at the same time.

[0035] In addition, the above drain pipe 22 should be equipped with a valve to control the conveying of the weighing assembly 3.

[0036] Since the rotating disc 13 is rotationally connected with the mounting base 1 through the ball bearing, it is necessary to equip it with a driving source to realize the continuous conveying function of the weighing assembly 3. Based on this requirement, the driving wheel is arranged on the top surface of the rotating disc 13 near the center of the inner ring surface, and the driving wheel is provided with a toothed portion on the center surface. An annular flange is arranged on the side wall surface of the mounting base 1, and a driving motor 15 is arranged on the bottom surface of the flange. The output end of the driving motor 15 vertically extends downward and is connected with a transmission gear at the end. The transmission gear is meshed with the toothed portion on the center of the driving wheel, so as to drive the directional rotation of the entire rotating disc 13.

[0037] The weighing assembly 3 includes a weighing cylinder 31 fixedly installed in the installation slot 14. The bottom of the weighing cylinder 31 is provided with an annular weighing sensor 632. In addition, an injection pipe 33 is arranged at the center of the bottom surface of the weighing cylinder 31. The injection pipe 33 is in communication with the inside of the weighing cylinder 31 and is arranged vertically downward as a whole, so as to be aligned with the top opening of one of the containers on the conveying belt 4, so as to discharge the liquid in the weighing cylinder 31 into the container.

[0038] Moreover, an electromagnetic valve should be arranged at the connection between the injection pipe 33 and the weighing cylinder 31.

[0039] A positioner 6 should be arranged on one side of each weighing cylinder 31. In the embodiment, an infrared range finder is used, and then the corresponding reflection ends 7 are arranged on the auxiliary supports of the conveying belt 4 and the supports on both sides of the mounting base 1. The positioner 6 is horizontally arranged and the emission end is outward, so that the reflection ends 7 are arranged at the same horizontal height.

[0040] As shown in the drawings, when the rotating disc 13 rotates, each positioner 6 can be aligned with the four reflecting ends 7 in turn, and the positioner 6 can determine the position of the weighing cylinder 31 according to the installation distance of the reflecting end 7, so as to cooperate with other components to inject liquid into the inside of the weighing cylinder 31, or to discharge liquid into the inside of the plastic bottle container through the injection pipe 33 at the bottom.

[0041] In the above weighing process, since the weighing cylinder 31 needs to be supplemented with liquid through the drain pipe 22, the top of the weighing cup should be arranged with an opening, and the exposed opening is extremely easy to cause dust to enter the inside of the liquid, causing pollution, so a through hole should be arranged at the center of the end cover 34 at the top of the weighing cylinder 31, and a foldable baffle plate 35 is arranged at the through hole, and the baffle plate 35 is supported by a spring, and when subjected to downward extrusion force, the baffle plate 35 will bend inward, thereby opening the through hole.

[0042] A telescopic cylinder 12 is further arranged at the bottom surface of the mounting plate 11, the main body part of the telescopic cylinder 12 is embedded in the mounting seat 1, and the output end at the top is fixedly connected with the center of the bottom surface of the mounting plate 11, so as to drive the entire water storage tank 2 to ascend and descend by using the telescopic function, so that the drain pipes 22 on both sides of the water storage tank 2 can move vertically, so as to force the baffle plate 35 to open by using downward extrusion force, thereby enabling the drain pipes 22 and the inside of the weighing cylinder 31 to communicate with each other, that is, when the telescopic cylinder 12 is displaced to the minimum stroke, the drain pipes 22 move vertically downward and open the baffle plate 35 to extend into the inside of the weighing cylinder 31.

[0043] A controller 5, such as LX3V-1616MR-A(D) programmable PLC controller 5, is further arranged at the top of the rotating disc 13, which is electrically connected with all the positioners 6 and the weighing sensor 632, and the controller 5 is further remotely connected with the telescopic cylinder 12, the driving motor 15, and the valves on the electromagnetic valve and the drain pipe 22 through a Bluetooth module, so as to receive the detected distance information in real time, and judge whether the position is at the feeding station or the filling station by comparing the measured distance, so as to run the corresponding program, and the structure can be combined with the drawings Figure 1 and the drawings Figure 4 It is observed that when the reflecting ends 7 and the positioners are relatively arranged, two sets of weighing assemblies 3 are located at the filling station, and two sets of weighing assemblies 3 are located at the preloading station.

[0044] When in the loading position: the cylinder contracts, the drain pipe 22 extends vertically downward and pushes open the partition plate 35, so that it is in communication with the inside of the weighing cylinder 31, at this time, the valve on the drain pipe 22 is opened, the liquid in the water storage tank 2 flows into the inside of the weighing cylinder 31 along the pipe, and is weighed in real time by the weighing sensor 632, until the specified weight is reached, the telescopic cylinder 12 extends upward, and the valve on the drain pipe 22 is closed at the same time;

[0045] When in the filling position: the electromagnetic valve is opened, the liquid in the inside of the weighing cylinder 31 flows into the inside of the container on the conveying belt 4 along the bottom injection pipe 33, and then the electromagnetic valve is closed.

[0046] The above two procedures are carried out synchronously and do not interfere with each other, so that in the above structure, the device can stably and continuously carry out quantitative filling, when the above two procedures are completed synchronously, the controller 5 controls the driving motor 15 to rotate, so that the next group of weighing cylinders 31 is aligned with the above position, thereby realizing continuous and uninterrupted work.

[0047] In addition, the structure can fill the containers on the two conveying belts 4 at the same time, so compared with the traditional filling device, the production efficiency is further improved, and the floor area occupied by the device is reduced.

[0048] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the present application.
