Description

Technical Field

[0002] In the field of existing edible oil filling technology, traditional filling equipment generally adopts the design of a material collecting hopper combined with an insertion tube to achieve accurate filling. However, this design faces significant technical challenges in actual operation: when the insertion tube penetrates into the bottle for filling operation, as the oil level gradually rises and exceeds the height of the insertion tube, the oil will inevitably adhere to and remain on the outer wall of the insertion tube. After filling is completed, when the insertion tube is withdrawn from the bottle, the edible oil attached to its surface often drips, which not only causes waste of edible oil, but more seriously, these dripping oil liquids will pollute the production environment, increase the cleaning cost, and even pose a potential threat to food safety. Therefore, there is a certain market demand for developing a leak-proof filling machine. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To better understand the present utility model, the following is combined with Figures 1 to 5To explain the implementation manner of the present utility model in detail.

[0020] It should be noted that the directions of "front, rear, left, right, up, and down" described in the text are all based on the directions of "front, rear, left, right, up, and down" in Figure 1 the [relevant reference].

[0021] Referring to Figures 1 to 5 , a leak-proof filling machine for edible oil of the present utility model includes a base 1. Above the base 1, there are two symmetrically arranged first telescopic mechanisms 3 (preferably hydraulic rods) on the left and right. The top telescopic ends of the two first telescopic mechanisms 3 jointly support a horizontally arranged support plate 2.

[0022] A circle of syringes 4 is fixedly arranged on the support plate 2. These syringes 4 are evenly distributed around the central axis. The bottom end of each syringe 4 is equipped with an insertion tube 5 extending downward. A check valve 6 is installed between the insertion tube 5 and the syringe 4. The check valve 6 ensures the one-way flow of the oil during the filling process and prevents backflow. The design of the insertion tube 5 avoids the problem of oil residue caused by traditional slender tubes because the insertion tube 5 can be quickly and cleanly retracted into the syringe 4 after filling. A fuel tank 7 is provided on the base 1 for storing the edible oil to be filled.

[0023] An annular plate 17 connecting all the syringes 4 is arranged on the support plate 2. An inner cavity 18 is arranged on the annular plate 17. The fuel tank 7 is connected to the inner cavity 18 on the support plate 2 through a hose 8. Each syringe 4 is provided with a through hole 19 connecting to the inner cavity 18.

[0024] A driving mechanism for driving the syringe 4 is arranged on the support plate 2. The driving mechanism includes a motor 13 installed on the support plate 2. The motor 13 is located at the center of all the syringes 4. A driving gear 14 is installed on the output shaft of the motor 13. A driven gear 15 meshing with it is arranged at the top of each syringe 4. A spiral groove is opened at the center of the driven gear 15. A spiral push rod 16 extending into the syringe 4 is inserted into the spiral groove. The bottom end of the spiral push rod 16 is provided with a piston head connected by rotation. The motor 13 is a forward and reverse motor 13. When the motor 13 is started, the spiral push rod 16 can be driven to rotate through gear transmission, so as to realize the pushing and pulling action of the spiral push rod 16 in the syringe 4, and inject the oil in the syringe 4 into the oil tank 28 through the insertion tube 5.

[0025] A plurality of card slots 11 corresponding to the filling heads are arranged on a sliding plate 9 horizontally sliding on the base 1. A weighing module 12 is installed in each card slot 11. The weighing module 12 includes a load-bearing plate 26 and a pressure sensor 27. When the oil tank 28 is placed in the card slot 11, the bottom of the oil tank 28 contacts the load-bearing plate 26 and applies pressure to the pressure sensor 27 to monitor the weight change of the oil tank 28 in real time.

[0026] At the bottom end of each syringe 4, there is also a positioning cone head 20 that can slide up and down. A buffer spring 21 is installed between the positioning cone head 20 and the syringe 4 to adapt to the mouths of oil tanks 28 with different shapes and sizes, and at the same time reduce the impact force when the insertion tube 5 is inserted.

[0027] Considering that the distribution position of the card slots 11 is relatively large, when the staff takes and places the oil tank 28 in the card slots 11, they need to frequently change positions, which is very inconvenient. To improve the efficiency of taking and placing the oil tank 28, a fixed rotating shaft 22 and a turntable 23 are provided on the sliding plate 9. The turntable 23 is fixed on the threaded end of the fixed rotating shaft 22 through a nut 24, which is convenient for adjusting the position of the card slots 11 to meet different filling requirements. There are indicator marks on the threaded end and the turntable 23, which is convenient for accurately adjusting the position.

[0028] A liquid level gauge 25 is installed on the storage oil tank 7 to monitor the oil liquid inventory and ensure timely replenishment.

[0029] Preparation stage before using the utility model: First, the second telescopic mechanism 10 expands, pushing the sliding plate 9 to extend out of the base 1. At this time, the staff loosens the nut 24 and rotates the turntable 23, and places the oil tanks 28 to be filled into the card slots 11 on the sliding plate 9 one by one. Then, through the indicator marks respectively set on the threaded end and the turntable 23 that correspond to each other, ensure that the mouth of the oil tank 28 is aligned with the corresponding insertion tube 5, and lock the turntable 23 again through the nut 24. Finally, start the system, and the weighing module 12 first records the initial weight of the oil tank 28.

[0030] Filling process of the utility model: First, start the motor 13 to make the driving mechanism start to work. The spiral push rod 16 pushes the oil liquid to be injected into the oil tank 28 through the insertion tube 5. During this period, the weighing module 12 monitors the weight change of the oil tank 28 in real time and feeds back the signal to the control system. As the oil liquid in the oil tank 28 increases, its weight also gradually increases. When the weight of the oil tank 28 reaches the preset value (that is, close to the capacity of the oil tank 28 or the set filling amount), the control system starts the first telescopic mechanism 3 for fine adjustment. The first telescopic mechanism 3 gradually expands, driving the support plate 2 and the filling components thereon to gradually rise, thereby driving the insertion tube 5 to rise synchronously, ensuring that the end of the insertion tube 5 always remains at a certain distance below the oil liquid surface, and avoiding the oil level being too high resulting in the oil liquid adhering to the insertion tube 5. Next, as the filling continues, after reaching the final set weight or capacity, the motor 13 stops working, and the filling is completed. After the filling is completed, the first telescopic mechanism 3 drives the support plate 2 to rise, so that the insertion tube 5 completely disengages from the oil tank 28. Finally, the second telescopic mechanism 10 expands, pushing the sliding plate 9 to extend out of the base 1. At this time, the staff loosens the nut 24 and rotates the turntable 23, and replaces the full oil tanks 28 on the turntable 23 with empty oil tanks 28 one by one. After completion, repeat the above steps again and prepare for the next round of filling.
