Description

Technical Field

[0001] This utility model relates to the technical field of integrated filling machines, specifically a vacuum filling machine. Background Technology

[0002] After the products are manufactured, they need to be filled. In the existing technology, vacuum filling machines can be used to fill the products.

[0003] However, after the existing vacuum filling machine is used, some items will remain at the opening of the filling tube. These items will drip onto the conveying mechanism. Some items will adhere to the surface of the conveying mechanism for a long time, causing the conveying mechanism to jam, which has certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum filling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A vacuum filling machine includes a conveying mechanism, a storage chamber, and a piston pump. The surface of the conveying mechanism is provided with a conveyor belt. The top center of the front of the two side plates of the conveying mechanism is provided with a protrusion. An inner cavity is opened at the protrusion of the back of the two side plates of the conveying mechanism. A dustproof net is fixedly connected to a certain longitudinal vertical plane of the inner cavity. The dustproof net divides the inner cavity into a suction fan inner cavity and a storage inner cavity. The suction fan inner cavity is located at the front end of the storage inner cavity. A suction fan is fixedly connected to the suction fan inner cavity. A dust outlet is opened at the bottom of the storage inner cavity and at the rear end of the dustproof net.

[0007] A vertical plate is provided on the top of one side plate of the conveying mechanism and at the protrusion. A horizontal plate is provided on the top of the vertical plate. A reciprocating cylinder is fixedly connected to the bottom center of the horizontal plate. The bottom of the reciprocating cylinder is connected to a piston rod. The piston rod is located at the piston pump. A filling pipe is provided at the bottom center of the piston pump. A connecting pipe is provided on the surface of the piston pump. The other end of the connecting pipe is connected to a storage compartment. The storage compartment is located on the side of one side of the conveying mechanism. A first solenoid valve is fixedly connected to the surface of the connecting pipe. A second solenoid valve is sleeved on the surface of the filling pipe.

[0008] Preferably, the reciprocating cylinder is electrically connected to the first solenoid valve, the second solenoid valve, and the suction fan.

[0009] Preferably, a fixing sleeve is fitted onto the surface of the piston pump, and the outer surface of the fixing sleeve is connected to the vertical plate via a connecting rod.

[0010] Preferably, the piston pump is fixed by a number of fixing bolts.

[0011] Preferably, the surface of the conveyor belt is provided with a plurality of limiting rings.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This utility model discloses a vacuum filling machine that uses the reciprocating motion of a reciprocating cylinder to fill the bottles. When the reciprocating cylinder contracts, the piston rod moves upward, causing the second solenoid valve to close and the first solenoid valve to open. At this time, the suction fan operates, sucking the remaining items on the surface of the filling tube into the storage cavity to prevent the items from falling onto the conveyor belt. When the reciprocating cylinder extends, the piston rod moves downward, causing the second solenoid valve to open and the first solenoid valve to close, while simultaneously turning off the suction fan, thus completing the filling of the bottles. Throughout the process, it can be seen that when filling stops, the suction fan sucks the remaining items on the filling tube into the storage cavity to prevent the items from dripping onto the conveyor belt and affecting its transport.

[0014] This utility model discloses a vacuum filling machine with a limit ring on the surface of the conveyor belt. The internal size of the limit ring matches the bottom size of the filling bottle, so the filling bottle can be fixed to the conveyor belt. When the suction fan is working, the filling bottle will not be displaced, which has certain practicality. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Please see Figure 1-2 This utility model provides a technical solution:

[0022] Example 1:

[0023] A vacuum filling machine includes a conveying mechanism 1, a storage bin 10, and a piston pump 14. The surface of the conveying mechanism 1 is provided with a conveyor belt 2, and the surface of the conveyor belt 2 is provided with a plurality of limiting rings 3. The internal dimensions of the limiting rings 3 match the bottom dimensions of the filling bottles, so the filling bottles can be fixed to the conveyor belt 2. When the suction fan 21 is working, it will not cause the filling bottles to shift, which has certain practicality.

[0024] Example 2:

[0025] The two side plates of the conveying mechanism 1 have protruding blocks 4 at the top center of the front. The two side plates of the conveying mechanism 1 have inner cavities at the protruding blocks 4 on the back. A dustproof net 5 is fixedly connected to a certain vertical plane of the inner cavity. The dustproof net 5 divides the inner cavity of the protruding block 4 into a suction fan inner cavity 20 and a storage inner cavity 6. The suction fan inner cavity 20 is located at the front end of the storage inner cavity 6. A suction fan 21 is fixedly connected to the suction fan inner cavity 20. A dust outlet 7 is opened at the bottom of the storage inner cavity 6 and at the rear end of the dustproof net 5.

[0026] Furthermore, a vertical plate 8 is provided on the top of one side plate of the conveying mechanism 1 and at the protrusion 4. A horizontal plate 9 is provided on the top of the vertical plate 8. A reciprocating cylinder 13 is fixedly connected to the bottom center of the horizontal plate 9. The bottom of the reciprocating cylinder 13 is connected to the piston rod 14. The piston rod 14 is located at the piston pump 15. A filling pipe 16 is provided at the bottom center of the piston pump 15. A connecting pipe 11 is provided on the surface of the piston pump 15. The other end of the connecting pipe 11 is connected to the storage compartment 10. The storage compartment 10 is located on the side of one side of the conveying mechanism 1. A first solenoid valve 12 is fixedly connected to the surface of the connecting pipe 11. A second solenoid valve 17 is sleeved on the surface of the filling pipe 16.

[0027] Example 3:

[0028] The reciprocating cylinder 13 is electrically connected to the first solenoid valve 12, the second solenoid valve 17, and the suction fan 21. Specifically, the reciprocating cylinder 13, the first solenoid valve 12, the second solenoid valve 17, and the suction fan 21 are all electrically connected to a controller, which controls them. When the controller controls the reciprocating cylinder 13 to retract, it will cause the second solenoid valve 17 to close and the first solenoid valve 12 to open, at which point the suction fan 21 will operate. Conversely, when the reciprocating cylinder 13 extends, it will cause the second solenoid valve 17 to open and the first solenoid valve 12 to close. During filling, the reciprocating cylinder 13 is started. When the reciprocating cylinder 13 retracts, it will cause the piston rod 14 to move upward, thereby causing the second solenoid valve 17 to close and the first solenoid valve 12 to open, at which point the suction fan 21 will operate. The suction fan 21 operates, sucking the items remaining on the surface of the filling tube 16 into the storage cavity 6, preventing the items from falling onto the conveyor belt. It also draws the items inside the storage compartment 10 into the piston chamber inside the piston pump 15 through the connecting tube 11. When the reciprocating cylinder 13 extends, it causes the piston rod 14 to move downward, which opens the second solenoid valve 17 and closes the first solenoid valve 12, while simultaneously turning off the suction fan 21. At this time, the items in the piston chamber inside the piston pump 15 will flow out from the filling tube 16 and be filled into the filling bottle, thus completing the filling of the bottle. In addition, the above-mentioned method of turning the suction fan 21 on and off is a mature existing technology, and its internal structure and circuit diagram will not be described in detail here.

[0029] Furthermore, a fixing sleeve 19 is fitted onto the surface of the piston pump 15. The outer surface of the fixing sleeve 19 is connected to the vertical plate 8 via a connecting rod 18. The fixing sleeve 19 fixes the piston pump 15 with several fixing bolts. Several threaded holes are opened on the surface of the fixing sleeve 19, and fixing bolts are threadedly connected to several threaded holes. By rotating the fixing bolts, the other end of the fixing bolts is pressed against the piston pump 15, thereby fixing the piston pump 15. In addition, a guide cylinder is provided on the surface of the threaded holes. The guide cylinder is integrally connected to the fixing sleeve 19, and after the fixing bolts are pressed against the guide cylinder, the top nut of the fixing bolts will contact the top of the guide cylinder.

[0030] Working principle: First, the operator places the filling bottle at the starting point of the conveying mechanism 1 and places it at the limiting ring 3. The filling bottle will be transported by the conveying mechanism 1 to the bottom of the piston pump 5 for filling. After filling is completed, a small amount of impurities remaining on the surface of the filling tube 16 will be sucked into the storage cavity 6 by the suction fan 21. The impurities in the storage cavity 6 will also be discharged from the dust outlet 7. It can be seen from the whole process that when filling stops, the suction fan 21 will suck the items remaining on the filling tube 16 into the storage cavity 6 to prevent the items from dripping onto the conveyor belt 2 and causing a certain impact on the conveying of the conveyor belt 2.

[0031] It should be noted that this utility model achieves vacuum filling by setting a piston pump 15.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
