[0002] Ice cream needs to be filled during production to divide it into cups, and a filling head is needed for this process.

[0003] The existing filling head was found to have flow deviation during use. This deviation is directly reflected in the weight consistency of the finished product. The actual weight of the same batch of products fluctuates widely, with some products far exceeding the reasonable range, which seriously affects the weight qualification rate. Therefore, it needs to be improved.

[0004] Therefore, it is necessary to invent a filling head structure that improves the filling accuracy of ice cream. Summary of the Invention

[0008] Preferably, the conveying assembly includes a support rod and a housing. The support rod is fixedly connected inside the feed pipe, and the housing is fixedly embedded in the feed pipe and located at the bottom of the support rod. One side of the housing is set as an open opening.

[0009] Preferably, a rotating shaft is embedded in the support rod, the bottom end of the rotating shaft extends into the housing, and a spiral blade is fixedly sleeved on the outside of the rotating shaft, the spiral blade being disposed inside the feed pipe.

[0016] The beneficial effects of this utility model are:

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 -Appendix Figure 5 This utility model provides a filling head structure for improving the filling accuracy of ice cream, including an inlet pipe 1, a flow meter 2, an electric butterfly valve 3, and an outlet pipe 4. The inlet pipe 1, flow meter 2, electric butterfly valve 3, and outlet pipe 4 are fixedly connected to each other.

[0028] The feed pipe 1 has four feed troughs 5 evenly distributed in a circular shape. The feed pipe 1 is designed with a conveying component, and an auxiliary component is provided between the feed pipe 1 and the discharge pipe 4.

[0029] The conveying assembly includes a support rod 6 and a housing 7. The support rod 6 is fixedly connected inside the feed pipe 1. The housing 7 is fixedly embedded in the feed pipe 1 and located at the bottom of the support rod 6. One side of the housing 7 is open. A rotating shaft 8 is embedded on the support rod 6. The bottom end of the rotating shaft 8 extends into the housing 7. A spiral blade 9 is fixedly sleeved on the outside of the rotating shaft 8. The spiral blade 9 is located inside the feed pipe 1. A servo motor 10 is fixedly connected to the top of the housing 7. A rotating shaft 11 is fixedly connected to the output shaft of the servo motor 10. The rotating shaft 11 passes through the housing 7. Both the rotating shaft 11 and the rotating shaft 8 are fixedly sleeved with synchronous pulleys 12. A synchronous belt 13 is sleeved on the outside of the two synchronous pulleys 12. The two synchronous pulleys 12 are driven and connected by the synchronous belt 13.

[0030] In this implementation scheme, the servo motor 10 drives the second rotating shaft 11 to rotate, the rotation of the second rotating shaft 11 drives the synchronous belt 13 to rotate, which in turn causes the first rotating shaft 8 to rotate, and the rotation of the first rotating shaft 8 drives the spiral blade 9 to rotate, thus conveying the ice cream downwards.

[0031] In order to reduce wear, the device adopts the following technical solution: the first rotating shaft 8 is connected to the support rod 6 and the housing 7 through a sealed bearing, and the second rotating shaft 11 is connected to the housing 7 through a sealed bearing. The connection through the sealed bearing can not only reduce wear, but also prevent ice cream material from entering the bearing.

[0032] In order to remove residual material from the discharge pipe 4, the device adopts the following technical solution: the auxiliary component includes an air pump 14, which is fixedly connected to one side of the housing 7. A pipe 15 is fixedly connected between the air pump 14 and the discharge pipe 4. A one-way valve 16 is provided on the pipe 15. The one-way valve 16 can prevent ice cream material from entering the pipe 15 when conveying ice cream.

[0033] To achieve the installation purpose, the device adopts the following technical solution: an installation plate 17 is fixedly sleeved on the outside of the feed pipe 1, a sealing gasket 18 is fixedly connected to the top of the installation plate 17, and multiple installation holes 19 are opened on the installation plate 17. The sealing gasket 18 can prevent ice cream material from escaping from the gap between the installation plate 17 and the ice cream storage box.

[0034] The usage process of this utility model is as follows: The feed pipe 1 of this device is passed through the slot on the ice cream storage box. Then, with the help of the mounting plate 17 and the mounting hole 19, this device can be installed on the ice cream storage box. The ice cream can then flow into the feed pipe 1 through the feed trough 5. Figure 5 As shown;

[0035] When filling is required, a filling container is placed at the bottom of the discharge pipe 4. Then, the electric butterfly valve 3 is opened, and the servo motor 10 is operated. The servo motor 10 drives the rotating shaft 11 to rotate, which in turn drives the synchronous belt 13 to rotate. This causes the rotating shaft 8 to rotate, which in turn drives the spiral blade 9 to rotate, thus conveying the ice cream downwards. The ice cream then enters the discharge pipe 4 through the flow meter 2 and the electric butterfly valve 3, and then falls into the filling container, thus completing the filling process.

[0036] After filling is completed, the electric butterfly valve 3 is closed and the servo motor 10 stops working. Then, the air pump 14 is controlled to work, and then air can be injected into the discharge pipe 4 under the action of the pipe 15, thereby blowing out the ice cream residue in the discharge pipe 4 and thus avoiding the presence of residue in the discharge pipe 4.

[0037] In actual use, this device can employ a PLC control system to integrate the coordinated operation of servo motor 10, flow meter 2, electric butterfly valve 3, and air pump 14 through a preset program. First, the PLC controls the electric butterfly valve 3 to open. Then, the PLC controls the servo motor 10 to rotate the spiral blades 9 to convey the ice cream. Simultaneously, the PLC receives real-time flow signals, such as pulse signals or analog signals, from the flow meter 2 and compares them with the set target filling volume. If there is a deviation, the PLC immediately sends an adjustment command to the servo motor 10. By precisely controlling the motor's speed or running time, the material pushing amount of the spiral blades 9 is adjusted. When the flow meter 2 reports that the actual flow is lower than the target value, the PLC increases the speed of the servo motor 10 or extends the running time to increase the pushing amount; conversely, it decreases the speed or shortens the time. After filling is completed, the PLC controls the electric butterfly valve 3 to close and the servo motor 10 to stop working. Then, it controls the air pump 14 to remove residual material.

[0038] In this application, the model and specifications of the servo motor 10, flow meter 2, electric butterfly valve 3 and air pump 14 need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so their specific model and specifications will not be described in detail. In addition, the electrical control and its principle of the above-mentioned components are clear to those skilled in the art, so the control method and circuit connection will not be described in detail.

[0039] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
