Description

Technical Field

[0001] The utility model relates to the technical field of liquid filling, in particular to an automatic capping and sealing filling machine for chemical products. Background Art

[0002] The automatic filling of chemical products is equipped with a special automatic filling production line, on which there is a conveyor belt for transporting filled bottles. The filled bottles go through operations such as loading, filling, capping, coding and labeling, boxing and sealing, and palletizing in sequence to complete the automatic filling of the filled bottles. After the whole process is completed, they are transported by forklift or manually.

[0003] After checking, a chemical liquid filling machine with a Chinese patent announcement number of "CN216336520U" can clamp the mouth of an empty bottle in a closed space formed by a rotating rod and a sealing cloth by driving the bottom end of the sealing cloth to contract, thereby preventing liquid from splashing out during filling. However, since a sealed space is formed at this time, the pressure in the bottle will gradually increase as the liquid enters. This may make it difficult to continue injecting the liquid because it is necessary to overcome the resistance caused by the pressure difference. Based on this, this application proposes an automatic capping and sealing filling machine for chemicals. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3A chemical product automatic capping and sealing filling machine includes a movable bracket 3 and a movable belt 7. The movable bracket 3 is rotatably connected to a screw rod 6, and a T-nut 5 is threadedly connected to the screw rod 6. The side wall of the T-nut 5 is fixedly connected to a splash-proof sleeve 9. It should be noted that the T-nut 5 slides freely on the slide rail 4, and the slide rail 4 limits the T-nut 5 to prevent the rotation of the screw rod 6 from driving the T-nut 5 to rotate, so that the T-nut 5 can only move repeatedly in the direction of the slide rail 4 and the belt 7 moves.

[0020] A motor 1 is fixedly connected to the upper end of the mobile bracket 3, and the output shaft of the motor 1 is fixedly connected to the screw 6. A guiding mechanism for guiding the screw 6 is installed on the mobile bracket 3, and the guiding mechanism includes two slide rails 4. The slide rails 4 are fixedly installed in the mobile bracket 3, and the T-nuts 5 slide on the slide rails 4.

[0021] A liquid inlet pipe 2 is fixedly connected to the upper end of the movable bracket 3, and the end of the liquid inlet pipe 2 away from the movable bracket 3 is communicated with the splash-proof sleeve 9. A number of liquid storage tanks 8 are placed on the movable belt 7. It should be noted that the movement of the movable belt 7 is intermittent, and the liquid storage tank 8 is exactly perpendicular to the splash-proof sleeve 9. After the liquid inlet pipe 2 injects liquid into the splash-proof sleeve 9, and the hydraulic telescopic machine 12 presses the cover on the liquid storage tank 8, when the hydraulic telescopic machine 12 moves upward, the movable belt 7 starts to move, driving the liquid storage tank 8 injected with liquid to move to the vertical bottom of the hydraulic telescopic machine 12.

[0022] A capping mechanism for capping the liquid storage tank 8 is installed on the moving belt 7, and the capping mechanism includes a capping bracket 11 and a hydraulic telescopic machine 12. The capping bracket 11 is placed next to the moving belt 7, and the hydraulic telescopic machine 12 is fixedly installed on the inner upper end of the capping bracket 11. The side wall of the telescopic end of the hydraulic telescopic machine 12 is fixedly connected to the connecting rod 10.

[0023] A fixed plate 18 is fixedly connected to the side wall of the movable bracket 3, a piston cylinder 15 is fixedly connected to the side wall of the fixed plate 18, a piston 16 is sealingly and slidingly arranged inside the piston cylinder 15, a connecting rod 10 is fixedly connected to the upper end of the piston 16, a liquid outlet pipe 14 is fixedly connected to the side wall of the piston cylinder 15, and the liquid outlet pipe 14 is communicated with the piston cylinder 15, a liquid suction pipe 17 is fixedly connected to the side wall of the piston cylinder 15, and the liquid suction pipe 17 is communicated with the piston cylinder 15.

[0024] One-way valves are installed in the liquid outlet pipe 14 and the liquid suction pipe 17. It should be noted that the function of the one-way valves in the liquid outlet pipe 14 and the liquid suction pipe 17 is that when the piston 16 moves upward, the one-way valve in the liquid suction pipe 17 opens, so that the liquid flowing out of the splash-proof sleeve 9 can only flow into the piston cylinder 15 through the liquid suction pipe 17; when the piston 16 moves downward, the one-way valve in the liquid outlet pipe 14 opens, so that the liquid in the piston cylinder 15 can only flow in through the liquid outlet pipe 14, thereby facilitating the collection of the liquid flowing out of the liquid outlet pipe 14.

[0025] A sealing ring 13 is fixedly connected inside the splash-proof sleeve 9. It should be noted that when the splash-proof sleeve 9 moves downward, the liquid inlet pipe 2 injects liquid, and at this time, the hydraulic telescopic machine 12 just covers the previous liquid storage tank 8. When the liquid inlet pipe 2 injects the liquid, the hydraulic telescopic machine 12 moves upward. After the upward movement is completed, the moving belt 7 drives the liquid storage tank 8 to move to the bottom of the hydraulic telescopic machine 12, and the hydraulic telescopic machine 12 moves downward to cover the liquid storage tank 8. In this way, the hydraulic telescopic machine 12, the splash-proof sleeve 9, the liquid inlet pipe 2 and the moving belt 7 can work staggered and non-interfering, forming a regular and orderly automated process.

[0026] The sealing ring 13 is made of anti-corrosion material.

[0027] In the utility model, the moving belt 7 is driven to move to the bottom of the splash-proof sleeve 9, the motor 1 is started to rotate forward, driving the screw 6 to rotate, so that the T-nut 5 drives the splash-proof sleeve 9 to move downward, and when the upper end of the liquid storage tank 8 enters the splash-proof sleeve 9, the rotation of the motor 1 is stopped. At this time, chemical liquid is injected into the splash-proof sleeve 9 through the liquid inlet pipe 2, so that the chemical liquid flows from the splash-proof sleeve 9 into the liquid storage tank 8. When the injection is completed, the telescopic end of the hydraulic telescopic machine 12 moves upward, driving the connecting rod 10 to move upward, and then the piston 16 slides upward in the piston cylinder 15. Under the action of the one-way valve in the suction pipe 17, the liquid splashed in the splash-proof sleeve 9 is sucked into the piston cylinder 15 through the suction pipe 17.

[0028] After the hydraulic telescopic machine 12 has moved up, the moving belt 7 drives the liquid storage tank 8 to move to the bottom of the hydraulic telescopic machine 12 again. At this time, the hydraulic telescopic machine 12 and the splash-proof sleeve 9 both move down, and the hydraulic telescopic machine 12 caps the liquid storage tank 8 that has been filled. The splash-proof sleeve 9 moves down to prepare for the new liquid storage tank 8 to be injected with chemical liquid. The pause time after the hydraulic telescopic machine 12 moves down is equal to the time when the liquid inlet pipe 2 is injected. This reciprocating process allows the liquid storage tank 8 to be filled and capped, thereby improving production efficiency.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
