Description

Technical Field

[0001] The utility model relates to the technical field of filling mechanisms, in particular to a bottom weighing type filling mechanism. Background Art

[0002] The most widely used filling method for edible oil filling machines is the flow meter metering method.

[0003] However, this type of flow meter metering filling equipment in the prior art has the following disadvantages:

[0004] 1. All are measured by the volume of oil. As the environment changes (seasonal changes, morning and noon temperature changes), the liquid will be affected by the temperature of the environment, and the principle of thermal expansion and contraction will cause the volume of the liquid to change, thus affecting the filling accuracy.

[0005] 2. The flow meter measurement method will also be affected by adverse factors of machine performance. Bubbles will be mixed into the edible oil during filling and added to the volume of the filling liquid, thereby changing the volume of the filling liquid and affecting the filling accuracy.

[0006] 3. The filling machine needs to prepare filling recipes at different temperatures according to the changes in oil temperature. The filling accuracy needs to be adjusted according to the real-time environmental changes.

[0007] Therefore, a bottom weighing filling mechanism is needed to improve the above-mentioned problems. Utility Model Content

A motor is provided on one side of the surface of the mounting frame through a mounting seat, and the output shaft end of the motor is connected to the material dividing screw transmission rod through a belt and a pulley. Since the weighing platform of the device is arranged at intervals, in order to ensure that the spacing between each storage bottle is equal to the spacing between the weighing platforms, a material dividing mechanism is required. The material dividing screw transmission rod of the material dividing mechanism can be rotated to transmit the filled bottles with equal spacing to the upper end of the empty bottle conveyor belt; thereby, it is convenient to simultaneously deliver multiple filled bottles to the upper end of the weighing platform at the same time.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A material dispensing mechanism is provided on one side of the fixed frame 1, and the material dispensing mechanism includes a mounting frame 10, a material dispensing spiral transmission rod 11, and a motor 12. A mounting frame 10 is provided on one side of the fixed frame 1, and a material dispensing spiral transmission rod 11 is movably provided on the upper end of the mounting frame 10 through a rotating shaft, and a motor 12 is provided on one side of the surface of the mounting frame 10 through a mounting seat, and the output shaft end of the motor 12 is connected to the material dispensing spiral transmission rod 11 through a belt and a pulley. Since the weighing platform 8 of the device is arranged at intervals, in order to ensure that the spacing between each storage bottle is equal to the spacing between the weighing platforms 8, a material dispensing mechanism is required. By rotating the material dispensing spiral transmission rod 11 of the material dispensing mechanism, the filled bottles with equal spacing can be transferred to the upper end of the empty bottle conveyor belt 6; thereby, it is convenient to simultaneously deliver multiple filled bottles to the upper end of the weighing platform 8 later;

[0026] Guide wheels 16 are movably provided on both sides of the weighing platform 8 through a rotating shaft, and the guide wheels 16 can facilitate the storage bottles to enter and exit the weighing platform 8, and the guide wheels 16 play the role of guiding and stabilizing the storage bottles;

[0027] A push cylinder 13 is provided on one side of the fixed frame 1, and a push plate 14 is fixedly provided on the movable end of the push cylinder 13. By extending the push cylinder 13 and cooperating with the push rod, multiple storage bottles can be pushed to the upper end of the weighing platform 8 at the same time, and after the storage bottles enter the upper end of the weighing platform 8, they are also located at the lower end of the filling nozzle 3;

[0028] A limit rail 15 is provided on one side of the full bottle conveyor belt 7, and the limit rail 15 can prevent the storage bottle filled with liquid from falling off the upper end of the full bottle conveyor belt 7;

[0029] The filling nozzles 3 and weighing platforms 8 are provided in plurality and are evenly spaced and distributed inside the fixed frame 1; the filling efficiency can be improved by using the plurality of filling groups and weighing platforms 8.

[0030] Working principle: When using this device, the internal liquid of the high-level buffer tank 2 can flow into the filling nozzle 3 under the action of gravity, and the operation of the filling nozzle 3 can be controlled by the filling cylinder;

[0031] The preparation process for each filling is as follows: the storage bottles to be filled can be transferred to the side of the weighing platform 8 through the empty bottle conveyor belt 6. At this time, the storage bottles and the weighing platform 8 are not in contact and cannot be weighed. If the weighing device 9 is directly set at the lower end of the empty bottle conveyor belt 6, the weighing accuracy will be seriously affected. At this time, by extending the push cylinder 13, the push plate can be used to push multiple storage bottles into the upper end of the weighing platform 8. In this way, the weighing device 9 can be used for weighing while filling. When the weighing device 9 weighs to the threshold, the filling nozzle 3 is controlled to stop working. In this way, the method of weighing at the lower end can improve the accuracy of filling;

[0032] After the filling of the storage bottle is completed, the full storage bottle cannot be pushed to the full bottle conveyor belt 7 directly by using the push plate. At this time, it is necessary to wait for the next batch of empty bottles to arrive, and then push the next batch of empty bottles by using the push plate, and use the empty bottles to push the full bottles on the upper end of the weighing platform 8 to the upper end of the full screen conveyor belt;

[0033] When the device is in use, the weighing platform 8 of the device is arranged at equal intervals. In order to ensure that the spacing between each storage bottle is equal to the spacing between the weighing platforms 8, the storage bottles can be pushed to the upper end of the weighing platform 8 by the pushing plate, and a dividing mechanism is needed. By rotating the dividing spiral transmission rod 11 of the dividing mechanism, the storage bottles are transmitted to the upper end of the empty bottle conveyor belt 6 at a fixed time and interval, and the filled bottles can be transmitted to the upper end of the empty bottle conveyor belt 6 at equal intervals; thereby, it is convenient to simultaneously deliver multiple filled bottles to the upper end of the weighing platform 8 to cooperate with the subsequent weighing device 9 to work, so as to improve the use effect of the device.
