[0025] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, what is described is only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0026] See Figure 1-6A filling machine outlet pipe joint comprises: a pipe body 1 and a connecting head 2, the connecting head 2 is fixedly welded to the top of the pipe body 1, and is used to connect the entire equipment to the output end of the filling machine. A guide assembly is provided in the pipe body 1, and the guide assembly comprises a main shaft 3, multiple turbines 4 and a power component. The multiple turbines 4 are rotatably sleeved in the pipe body 1 through bearings 9, the main shaft 3 is vertically fixedly sleeved in the middle of the multiple turbines 4, and the power component is arranged on the upper side of the topmost turbine 4. The power component comprises a retaining ring 5, multiple balls 6 and a spring 7. The multiple balls 6 are all rollingly embedded in the outside of the retaining ring 5, and a threaded groove 8 is opened on the inner wall of the pipe body 1. The multiple balls 6 are all rollingly embedded in the threaded groove 8, and the spring 7 is arranged between the turbine 4 and the retaining ring 5 through a guide component.

[0027] The guide component includes a support ring 10, a support frame 11 and two sliding rods 12. The support ring 10 is fixedly sleeved on the top of the main shaft 3, the support frame 11 is fixedly sleeved inside the retaining ring 5, and the two ends of the spring 7 are fixedly connected to the top of the support ring 10 and the bottom of the support frame 11 respectively. The two sliding rods 12 are vertically fixedly installed on the upper side of the support ring 10 and the bottom side of the support frame 11, and the support frame 11 is slidably sleeved with the two sliding rods 12.

[0028] The device is connected to the output end of the filling machine through the connector 2 at the top. When filling edible oil, the oil enters the tube body 1 through the connector 2 and impacts the turbine 4. The turbine 4 rotates under the support of the bearing 9, driving the support ring 10 to rotate. The support ring 10 drives the support frame 11 to rotate through two slide bars 12 and the spring 7. The support frame 11 drives the snap ring 5 to rotate. The snap ring 5 drives multiple balls 6 to roll and spiral up in the thread groove 8. The snap ring 5 spirals and rises under the interference of the thread groove 8, driving the support frame 11 to rise. The support frame 11 stretches the spring 7. When the spring 7 is stretched to the upper limit length, the turbine 4 stops rotating. Under the continuous output impact force of the edible oil, the turbine 4 Keep it still, the spring 7 is always in a stretched state. After the filling machine outputs the preset amount of oil, it stops running, the oil in the output pipe loses the delivery pressure, the impact force on the turbine 4 is released, and the spring 7 recovers its original length. Under the action of the tensile force of the spring 7, the clamping ring 5 spirals down to drive the turbine 4 to rotate again. The turbine 4 provides power for the oil remaining in the pipe body 1 and the oil pipeline, so that the oil can be discharged. In this way, the guide component can store energy when the filling machine is running, and release energy after the filling machine stops working to provide delivery pressure for the oil remaining in the oil pipeline. The preset output amount of oil can be filled into the oil barrel to ensure the accuracy of the net content of the filling. Example 2

[0029] A blocking component is provided at the bottom of the turbine 4 located at the bottom, and a measuring component is provided at the bottom of the blocking component.

[0030] The sealing component includes a cylinder 13, a sleeve 14, a baffle 15 and multiple blockages 16. The cylinder 13 is fixedly installed at the bottom of the turbine 4. The baffle 15 is fixedly sleeved in the cylinder 13 and has multiple overflow holes 17 inside. The sleeve 14 is vertically slidably sleeved at the bottom of the main shaft 3. It can only slide up and down at the bottom of the main shaft 3 and rotates with the main shaft 3. It cannot rotate relative to the main shaft 3. Multiple blockages 16 are fixedly connected to the sleeve 14 through a connecting rod 18 and are evenly distributed in a ring shape. Multiple blockages 16 correspond to multiple overflow holes 17 respectively and are interference fit. Overflow gaps 19 are formed between adjacent blockages 16.

[0031] The measuring components include a float 20, a threaded barrel 21 and a self-locking nut 22. A thread is provided on the outer side of the bottom of the sleeve 14. The threaded barrel 21 is threadedly sleeved on the bottom of the sleeve 14. The self-locking nut 22 is threadedly sleeved on the bottom of the sleeve 14 and is located on the upper side of the threaded barrel 21. The float 20 is fixedly installed on the bottom of the threaded barrel 21. The position of the threaded barrel 21 can be limited by the self-locking nut 22, thereby adjusting the position height of the float 20.

[0032] The surfaces of the materials used in the device are coated with non-oleophilic coatings or are made of non-oleophilic materials.

[0033] A limiting component is provided between the main shaft 3 and the sleeve 14, and the limiting component includes a compression spring 23 and a limiting ball 24. A placement cavity 25 is horizontally opened inside the main shaft 3, the compression spring 23 is horizontally arranged, and the end is fixedly connected to the inner wall of the placement cavity 25. The limiting ball 24 is movably embedded in the placement cavity 25 and is close to the sleeve 14. A card slot 26 is opened on the inner wall of the sleeve 14.

[0034] During the filling process, the oil volume in the oil barrel can be detected by the measuring component and the position of the float 20 can be adjusted. The standard is that when the oil height in the oil barrel reaches the preset net content value, the limit ball 24 is located in the slot 26 under the action of buoyancy.

[0035] Adjust the position of the float 20 to the standard position. During the filling process, when the oil level is close to the preset height, the float 20 is in contact with the oil and is subjected to buoyancy. As the oil continues to rise, the float 20 rises, pushing the sleeve 14 up. When the oil level reaches the preset net content height value, the slot 26 moves to the area of ​​the limiting ball 24. The limiting ball 24 is pushed out by the compression spring 23 and combined with the slot 26 to form a limiting mechanism. The sleeve 14 no longer moves. At the same time, multiple blocking blocks 16 are in close contact with the retaining frame 15 to achieve blocking, ensuring that excess oil no longer enters the oil barrel, further ensuring the filling accuracy. When the next filling is performed, under the impact of the oil, the blocking block 16 is separated from the retaining frame 15, and the limiting ball 24 compresses the compression spring 23 and separates from the slot 26.

[0036] If the float 20 automatically moves downward after the oil drum is detached and the filling machine is not started, that is, the limit ball 24 is located in contact with the slot 26, it indicates that the amount of oil output by the filling machine is too small;

[0037] If the oil barrel is detached and the float 20 is manually moved downward to disengage the slot 26 from the limiting ball 24, and oil still flows out, it indicates that the filling machine has output too much oil;

[0038] If the above situation occurs, the operating parameters of the filling machine should be repaired or adjusted.

[0039] If the float 20 is manually moved downward so that the locking groove 26 is disengaged from the limiting ball 24 and no excess oil flows out, it indicates that the filling machine is operating normally.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
