[0002] Under-cap filling method, also known as under-cap filling method, is a common filling method at home and abroad. Generally, under-cap filling is to press the filling head down first, and the periphery of the lower edge of the filling head and the periphery of the can shoulder on the outside of the can mouth are pressed and sealed, forming an enclosed space separated from the outside inside. In the sealed space, the valve cover placed above the can mouth is sucked and lifted. Filling can only be done in the enclosed space through the gap between the bottom of the valve cover and the top of the aerosol can mouth.

[0003] However, most of the under-cap filling machines in the prior art have difficulty in integrating the positioning of the can body and the prevention of material splashing generated during the filling of the can body. As a result, the can body is easily deviated, affecting the filling accuracy, and the splashing material will splash onto the ground and pollute the surrounding working environment.

[0004] Therefore, the utility model provides a can feeding mechanism for an under-cap filling machine to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] The utility model provides a can feeding mechanism for an under-cap filling machine, such as Figure 1-5 As shown, the filling machine includes a filling machine body 1, the top of the filling machine body 1 is rotatably connected to a bidirectional threaded rod 2, the outer surface of the bidirectional threaded rod 2 is threadedly connected to two threaded sleeves 3, the outer surface of the threaded sleeve 3 is fixedly connected to a positioning ball 4, the outer surface of the bidirectional threaded rod 2 is fixedly connected to a gear 5, and the interior of the filling machine body 1 is provided with a surrounding plate 6, the inner side of the surrounding plate 6 is fixedly connected to a rack 7 engaged with the gear 5.

[0026] When the bidirectional threaded rod 2 rotates, the two threaded sleeves 3 that are threadedly matched with it can respectively drive the positioning balls 4 to approach each other by utilizing the opposite threads on both sides, so that the tank body can be positioned when the two positioning balls 4 approach each other to a certain position, thereby preventing the tank body from moving and offsetting, causing material leakage during tank filling, and affecting the accuracy of tank filling. In addition, during the rotation of the bidirectional threaded rod 2, the gear 5 can be driven to rotate synchronously, so that the rack 7 engaged with the gear 5 can drive the enclosure 6 to move upward, so that when the enclosure 6 moves upward to a suitable height, the tank body being filled can be surrounded, thereby preventing the material from directly splashing onto the ground during tank filling, thereby avoiding the material splashing onto the ground from causing pollution to the surrounding working environment.

[0027] A telescopic rod 8 is fixedly connected to the top of the rack 7 , and one end of the telescopic rod 8 away from the rack 7 is fixedly connected to the outer wall of the filling machine body 1 .

[0028] The telescopic rod 8 provides the rack 7 with a fixed point, and the telescopic characteristics provided by the telescopic rod 8 enable the rack 7 to move up and down. The connection between the telescopic rod 8 and the rack 7 makes the rack 7 have good stability when moving, preventing the rack 7 from falling in the air and unable to form a normal meshing state with the gear 5, so that the rack 7 and the gear 5 can be in a stable meshing state, thereby ensuring the stability of the enclosure 6 when moving, so that the enclosure 6 can move smoothly to prevent the tank body from splashing materials.

[0029] The outer surface of the threaded sleeve 3 is fixedly connected to a limit rod 9 , and the top of the filling machine body 1 is provided with a limit groove 10 for the limit rod 9 to slide.

[0030] The limiting groove 10 provides the limiting rod 9 with a restricted moving space, so that the threaded sleeve 3 can move smoothly when the two-way threaded rod 2 rotates by virtue of the cooperation of the limiting rod 9 in the limiting groove 10, preventing the threaded sleeve 3 from rotating synchronously with the rotation of the two-way threaded rod 2 due to lack of restricted space, thereby ensuring that the threaded sleeve 3 can drive the positioning ball 4 to move smoothly to position the tank body, and preventing the leakage of material caused by the mismatch between the position of the filling mechanism on the filling machine body 1 and the filling of the tank body during filling.

[0031] A slot 11 for the sliding of the enclosure 6 is provided inside the filling machine body 1 , and a through hole 12 for the sliding of the rack 7 is provided inside the filling machine body 1 .

[0032] The card slot 11 provides space for the enclosure 6 to be embedded, so that the enclosure 6 can be driven by the rack 7 to move up and down smoothly using the card slot 11 without offsetting or falling off, so that the enclosure 6 can smoothly surround the tank body to prevent splashing. The through hole 12 provides space for the rack 7 to move, so that when the rack 7 is engaged by the rotation of the gear 5, the enclosure 6 can be driven to move smoothly, preventing the rack 7 from being interfered with by the movement of the filling machine body 1, causing the enclosure 6 to be unable to move.

[0033] A slot 13 for the bidirectional threaded rod 2 to rotate is provided on one side of the enclosure 6 , and a handle 14 for driving the bidirectional threaded rod 2 to rotate is provided on the outer wall of the filling machine body 1 .

[0034] The slot 13 provides space for the two-way threaded rod 2 to be placed, preventing movement interference between the enclosure 6 and the two-way threaded rod 2, which causes the two to be unable to operate smoothly and normally. The slot 13 is used to ensure that the enclosure 6 will not be restricted by the two-way threaded rod 2 when moving upward, and the two-way threaded rod 2 will not be limited by the enclosure 6 and unable to rotate, and the handle 14 provides the two-way threaded rod 2 with a force point for rotation, which is convenient for the staff to manually rotate the two-way threaded rod 2.

[0035] A drop opening 15 is provided inside the filling machine body 1 , and a placement groove 16 is provided on the top of the filling machine body 1 .

[0036] The drop opening 15 provides space for the partially leaked material to be discharged downward during filling of the can, thereby preventing the leaked material from being scattered directly on the filling machine body 1 and affecting its overall appearance, and avoiding the material from being scattered on the filling machine body 1 for a long time and causing pollution and corrosion thereon. The placement groove 16 provides space for the can to be placed, thereby providing the can with a primary limit point, further ensuring the stability of the can during filling.

[0037] A box body 17 with an opening at one side is fixedly connected to the bottom of the filling machine body 1 , and a carrying plate 18 is slidably connected to the bottom of the inner wall of the box body 17 .

[0038] The box body 17 provides storage space for the supporting plate 18, so that the supporting plate 18 has good stability when being pulled out of the box body 17, and the supporting plate 18 provides a storage point for materials dropped through the drop port 15, so as to facilitate subsequent centralized processing of the materials.

[0039] Working principle:

[0040] When it is necessary to use this device to fill the tank body, first place the tank body in the placement groove 16, and then turn the handle 14 to drive the bidirectional threaded rod 2 to rotate. When the bidirectional threaded rod 2 rotates, the two threaded sleeves 3 threadedly matched with it can use the opposite threads on both sides of the bidirectional threaded rod 2 to approach each other, prompting the two threaded sleeves 3 to drive the positioning balls 4 to approach each other to a certain position, so that the tank body can be positioned, and the rotation of the bidirectional threaded rod 2 can drive the gear 5 to rotate synchronously, so that the rack 7 engaged with the gear 5 can drive the enclosure 6 to move upward, so that when the enclosure 6 moves upward to a certain position, it can surround the tank body to prevent splashing.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
