[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0026] See also Figures 1 to 3 As shown, a linear filling and plugging device includes a cabinet 7, a transmission line 1, a filling assembly and a plugging assembly. The cabinet 7 is fixedly set on the ground, the transmission line 1 is fixedly set above the cabinet 7, the transmission line 1 is used to transmit the bottle body, the filling assembly and the plugging assembly are fixedly set on one side of the transmission line 1, and are arranged in sequence along the transmission direction of the transmission line 1. The filling assembly is used to fill the liquid into the bottle body, and the bottle body after filling is transported to one side of the plugging assembly by the transmission line 1. The plugging assembly is a prior art. When it is implemented, the cap assembly 8 is placed to put the bottle plug at the bottle mouth of the bottle body filled with liquid, and then the bottle plug is pressed by the pressure rod assembly 9, which will not be repeated here.

[0027] The filling assembly includes a support frame 2, a lifting assembly 4, a plurality of filling tubes 3, a liquid adding tube 5, a liquid storage tank and a diversion assembly 6, wherein the support frame 2 includes a fixed rod 21 and a fixed plate 22, there are two fixed rods 21, the two fixed rods 21 are fixedly arranged on the top surface of the cabinet 7 at intervals, the fixed plate 22 is fixedly arranged on the top of the fixed rod 21, and the fixed plate 22 is partially suspended above the transmission line 1, for supporting the lifting assembly 4. The lifting assembly 4 includes a connecting plate 41 and a hydraulic telescopic cylinder 42, the connecting plate 41 is horizontally arranged between the fixed plate 22 and the transmission line 1, the hydraulic telescopic cylinder 42 is vertically fixed on the top surface of the fixed plate 22, the output end of the hydraulic telescopic cylinder 42 passes through the fixed plate 22 and is fixedly connected to the connecting plate 41, for driving the connecting plate 41 to rise and fall.

[0028] In this embodiment, the connecting plate 41 is a rectangular plate, and the length direction of the connecting plate 41 is parallel to the transmission direction of the transmission line 1. A plurality of filling tubes 3 are arranged at intervals along the length direction of the connecting plate 41, and the gap between two adjacent filling tubes 3 is equal to the distance between the bottle mouths of two adjacent bottles on the transmission line 1. One end of the liquid adding tube 5 is connected to the top of the filling tube 3 to provide liquid to the filling tube 3. In this embodiment, a liquid storage tank (not shown in the figure) is placed inside the cabinet 7, and the liquid storage tank is used to store the liquid transported into the bottle body. One end of the liquid adding tube 5 is connected to the liquid storage tank through the pump body, and the other end of the liquid adding tube 5 is connected to the filling tube 3 after passing through the connecting plate 41. Preferably, the filling tube 3 is screwed to the connecting plate 41 to facilitate the disassembly and maintenance of the filling tube 3.

[0029] During implementation, the transmission line 1 moves the bottle that needs to be filled with liquid to the bottom of the filling assembly. At this time, the filling tube 3 is vertically arranged above the bottle mouth of the bottle, and then the lifting assembly 4 is started. The lifting assembly 4 drives the connecting plate 41 to move, and at the same time, the connecting plate 41 drives the filling tube 3 to move downward until the output end of the filling tube 3 is located inside the bottle. At this time, the liquid adding tube 5 transports a certain amount of liquid to the inside of the filling tube 3 and pours it into the bottle through the filling tube 3. After the filling is completed, the lifting assembly 4 is reset, and then the transmission line 1 is started, and the above steps are repeated to fill the subsequent bottles.

[0030] The diverter assembly 6 is slidably sleeved at the lower part of the filling tube 3 to prevent the filling tube 3 from spraying empty onto the transmission line 1, causing material loss. In this embodiment, a positioning ring 31 is fixedly sleeved on the outer wall of the filling tube 3, and the diverter assembly 6 includes a diverter tube 61. The diverter tube 61 is slidably sleeved at the outer side of the filling tube 3. The top wall inside the diverter tube 61 abuts against the top surface of the positioning ring 31, that is, the positioning ring 31 is used to prevent the diverter tube 61 from sliding downward. A convex ring 611 is provided inside the diverter tube 61. The inner diameter of the convex ring 611 is the same as the outer diameter of the filling tube 3. The bottom end of the filling tube 3 extends to the inner side of the convex ring 611. The convex ring 611 and the bottom end of the filling tube 3 divide the interior of the filling tube 3 into an upper liquid storage space 612 and a lower liquid discharge space 613. A liquid outlet 32 ​​is provided on one side of the filling tube 3, and the liquid outlet 32 ​​is connected to the liquid storage space 612.

[0031] It should be noted that the bottom end of the filling tube 3 is in contact with the inner side of the convex ring 611, so that the liquid storage space 612 becomes a closed space, that is, the liquid in the liquid storage space 612 will not flow into the liquid discharge space 613. Preferably, a rubber ring 33 is fixed on the inner side wall of the convex ring 611 and the inner wall of the top of the shunt tube 61, and the radial sides of the rubber ring 33 are in contact with the filling tube 3 and the shunt tube 61, respectively. In this way, the airtightness of the liquid storage space 612 is improved. Furthermore, the convex ring 611 and the top of the shunt tube 61 are respectively set as sealing bearings to achieve the airtightness of the liquid storage space 612.

[0032] During implementation, the transmission line 1 moves the bottle body that needs to be filled with liquid to the bottom of the filling assembly. At this time, the central axis of the filling tube 3 is located above the bottle body, and then the lifting assembly 4 is started. The lifting assembly 4 drives the filling tube 3 and the shunt tube 61 sleeved on the outside of the filling tube 3 to move downward. During the downward movement of the shunt tube 61, the bottom end of the shunt tube 61 will abut against the bottle mouth, so the shunt tube 61 will not move downward, and the filling tube 3 will continue to move until the liquid outlet 32 ​​of the filling tube 3 is connected with the discharge space 613. At this time, the liquid adding tube 5 transports a certain amount of liquid to the inside of the filling tube 3, and the liquid is discharged into the bottle body through the discharge space 613 to complete the filling of the liquid. After the filling is completed, the lifting assembly 4 is reset, and the shunt tube 61 can be reset by sliding downward by its own weight. Preferably, a spring 64 is sleeved on the outer wall of the filling tube 3, and the two ends of the spring 64 are respectively abutted against the connecting plate 41 and the shunt tube 61. To help the shunt tube 61 reset.

[0033] It should be noted that when a bottle leaks at the lower part of the filling assembly on the transmission line 1, since there is no bottle body to support the shunt tube 61, when the liquid adding tube 5 transports liquid to the inside of the filling tube 3, the liquid will be stored in the liquid storage space 612, and will not be sprayed on the transmission line 1 to cause material waste. Preferably, a liquid return pipe 65 is provided on one side of the liquid storage space 612, and the two ends of the liquid return pipe 65 are respectively connected to the liquid storage space 612 and the liquid storage tank. During implementation, the liquid in the liquid storage space 612 can be returned to the inside of the liquid storage tank through the liquid return pipe 65.

[0034] Preferably, a pressure ring 62 is fixedly sleeved on the outer wall of the shunt tube 61 for pressing the top side wall of the bottle mouth. The pressure ring 62 can be adapted to bottles of different diameters. Furthermore, a rubber pad 63 is fixedly provided on the bottom surface of the pressure ring 62 to prevent the pressure ring 62 from causing wear to the bottle body.

[0035] When the utility model is implemented, the bottle body that needs to be filled with liquid is moved to the bottom of the filling assembly through the transmission line 1, and then the lifting assembly 4 is started to drive the filling tube 3 and the shunt tube 61 to move toward the bottle body. First, the pressure ring 62 fixedly mounted on the outer wall of the shunt tube 61 abuts against the bottle mouth, and the shunt tube 61 cannot continue to move downward. At this time, the lifting assembly 4 continues to drive the filling tube 3 down until the liquid outlet 32 ​​of the filling tube 3 is connected with the drainage space 613 of the shunt tube 61, and then a certain amount of liquid is transported to the inside of the filling tube 3 through the liquid adding tube 5, and the liquid is discharged into the bottle body through the drainage space 613 to complete the filling. After the filling is completed, the transmission line 1 is started to move the bottle body to the side of the plugging assembly for plugging.

[0036] When a bottle leaks below the filling assembly, since there is no bottle body to support the diverter tube 61, the liquid outlet 32 ​​of the filling tube 3 is located inside the liquid storage space 612, and the liquid transported by the liquid adding tube 5 to the inside of the filling tube 3 will flow back to the liquid storage tank through the return pipe 65, and will not be sprayed on the transmission line 1 to cause material waste.

[0037] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
