[0020] DETAILED DESCRIPTION In order to make the purpose and advantages of the present application more clear and explicit, the present application will be specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the present application, and does not strictly limit the scope of the specific claims of the present application.

[0021] As shown in

[0022] As shown in Figures 1-3 A full-weighing mechanism of a filling machine includes two weighing mechanisms, three support plates 1 and three horizontal drive groups, and the support plate 1 and the weighing mechanism can be fixedly connected to the rack of the filling machine;

[0023] Among them, the installation area is arranged between the two weighing mechanisms, and the conveying line for conveying the bottles 9 can be installed in the installation area, and the bottles 9 can be moved in the installation area by the conveying line.​

[0024] The three push rods 2 are slidably connected to the three support plates 1, and the three horizontal drive groups are respectively in transmission connection with the three push rods 2, so that the push rods 2 can be driven to slide horizontally on the support plates 1 through the horizontal drive groups.

[0025] As shown in the figure, Figure 1 the horizontal drive group comprises a driving motor 10, the driving motor 10 can be diversified controlled according to the programmable controller, the driving motor 10 is fixedly connected to the filling machine rack, a synchronous pulley set is installed on the support plate 1 and in transmission connection with the driving motor 10, and the synchronous pulley set is in transmission connection with the push rod 2, at this time, the driving motor 10 can be started to output rotary kinetic energy, which is then converted into linear motion by the synchronous pulley set and transmitted to the push rod 2, so that the push rod 2 can be driven to move, and the driving motor 10 and the synchronous pulley set can be cooperated to realize precise control.

[0026] Specifically, as shown in the figures, Figure 1 and Figure 3 the synchronous pulley set comprises two driving wheels 11 rotatably connected to the support plate 1, the outer side of the two driving wheels 11 is in transmission connection with a driving belt 12, the outer side of the driving belt 12 is fixedly connected with a connecting block 13, the connecting block 13 is fixedly connected with the push rod 2, and one of the two driving wheels 11 is in transmission connection with the driving motor 10, so that the driving wheel 11 can be driven to rotate when the driving motor 10 is started, and the driving belt 12 can be driven to move when the driving wheel 11 rotates, thereby relatively simply driving the connecting block 13 on the outer side of the driving belt 12 to move linearly.

[0027] As shown in the figure, Figures 1-2 the three push rods 2 are fixedly connected with three fixed seats 3, the three fixed seats 3 are arranged side by side, the first side bottle-pushing finger 4, the middle bottle-pushing finger 5 and the second side bottle-pushing finger 6 are respectively fixedly connected to the three fixed seats 3, and the first side bottle-pushing finger 4 and the second side bottle-pushing finger 6 are respectively located on the two sides of the middle bottle-pushing finger 5.

[0028] The first side bottle-pushing finger 4, the middle bottle-pushing finger 5 and the second side bottle-pushing finger 6 are located on the upper side of the weighing mechanism.

[0029] At this time, the bottles 9 are driven to move in the installation area through the conveying line, the conveying line is stopped when the first group of bottles 9 move into the first moving area between the first side bottle-pushing finger 4 and the middle bottle-pushing finger 5, so that the bottles 9 stop moving, and then the three driving motors 10 can be started to drive the first side bottle-pushing finger 4, the middle bottle-pushing finger 5 and the second side bottle-pushing finger 6 to move synchronously to the left side, and the middle bottle-pushing finger 5 moves the first group of bottles 9 to the first weighing mechanism.

[0030] After the bottle 9 moves, the first group of bottles 9 can be weighed by the weighing mechanism, and at the same time, the conveying line can be started to drive the bottle 9 to move in the installation area. When the second group of intermediate bottle fingers 5 moves to the second moving area between the intermediate bottle fingers 5 and the second side bottle fingers 6, the conveying line is stopped again, so that the bottle 9 stops moving, and then the three drive motors 10 are started to drive the first side bottle fingers 4, the intermediate bottle fingers 5 and the second side bottle fingers 6 to move synchronously to the right side. The intermediate bottle fingers 5 move the second group of bottles 9 to the second weighing mechanism, and the first side bottle fingers 4 move the first group of bottles 9 to the conveying line;

[0031] After the bottle 9 moves, the second group of bottles 9 can be weighed by the weighing mechanism, and the conveying line is started to drive the third group of bottles 9 to move in the installation area, and at the same time, the first group of bottles 9 is moved out of the installation area.

[0032] In this way, the weighing of multiple groups of bottles 9 can be completed during the movement of the conveying line, and by alternately weighing two groups of bottles 9, the remaining bottles 9 can be transported during the weighing process, thereby improving the weighing efficiency of the bottles 9.

[0033] The first side bottle fingers 4, the intermediate bottle fingers 5 and the second side bottle fingers 6 each include a main plate mounted on the fixed seat 3, and four support plates are fixedly connected to the lower side of the main plate. The four support plates serve as fingers that contact and push the bottles 9.

[0034] As shown in Figure 1 The two weighing mechanisms each include a support body 14, which can be fixedly connected to the rack of the filling machine. A set of weighing sensors 7 is fixedly connected to each of the two support bodies 14. The number of weighing sensors 7 in each set is preferably four. The upper side of the weighing sensor 7 is fixedly connected to a weighing tray 8. When the bottle 9 moves to the upper side of the weighing tray 8, the bottle 9 can be weighed by the weighing sensor 7, thereby enabling simultaneous weighing of multiple bottles 9 in the same group.

[0035] The first side bottle fingers 4, the intermediate bottle fingers 5 and the second side bottle fingers 6 can be connected by screws, magnetically attracted or clamped. In this technical solution, the preferred method is magnetic attraction, which specifically includes a magnet or an electromagnet fixedly connected to the fixed seat 3. The material opposite the fixed seat 3 of the first side bottle fingers 4, the intermediate bottle fingers 5 and the second side bottle fingers 6 is iron, which can be easily replaced according to the specifications of the bottle.

[0036] The two sides of the fixed seat 3 can also be provided with positioning and clamping devices for positioning and reinforcing the first side bottle fingers 4, the intermediate bottle fingers 5 and the second side bottle fingers 6.

[0037] Meanwhile, the technical scheme can set intermittent weighing and full weighing in cooperation with the man-machine interface, and the two kinds of weighing modes.

[0038] The weighing system is composed of front weighing (weighing empty bottle weight) and rear weighing (bottle 9 weight after filling).

[0039] Intermittent weighing: whether full weighing is selected according to the process requirement of the user, the interval time and quantity of weighing can be set on the man-machine interface.

[0040] Full weighing: each bottle of the filling machine is weighed, and the system saves and compares all data.

[0041] Advantages of full weighing: the weighing is realized without speed reduction by using the residence time during filling (this function does not affect the production speed of the whole machine). The reciprocating pushing form can also provide sufficient reaction time for the electronic scale, so that the data of the electronic scale is more stable.

[0042] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to the conventional means in the art, unless otherwise specified and limited.
