Description

Technical Field

[0001] The utility model belongs to the field of filling gun feeding structures, in particular to a filling gun feeding structure with an automatic closing structure. Background Art

[0002] Floral water is primarily used for masking odors, sterilizing, disinfecting, cleaning, and adding fragrance. It generally has a pure, unscented aroma, and even at temperatures as low as -5°C, it remains turbid and resistant to precipitation. For this reason, floral water is increasingly popular, serving as a summer hygiene product for mosquito repellent, itching relief, sterilization, and body odor removal. However, the processing of floral water requires a filling gun to deliver the liquid from the container into the packaging container for quantitative delivery.

[0003] However, when the existing filling gun is in use, it mostly relies on the electronic control structure of the valve to supply the liquid in a quantitative manner. However, the opening and closing of the valve requires external electric drive to realize the opening and closing operation of the valve. Therefore, if the filling gun cannot be closed in time after filling, it is easy to cause liquid overflow.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking improvement, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created, and a filling gun feeding structure with an automatic closing structure is provided to solve the existing problem that when feeding liquid, it mostly relies on the electric control structure of the valve for quantitative supply, but the opening and closing of the valve requires external electric drive to realize the opening and closing operation of the valve. If the filling gun cannot be closed in time after filling, it is easy to cause liquid overflow. Utility Model Content

[0005] The utility model proposes a filling gun feeding structure with an automatic closing structure, which solves the problem in the prior art that when feeding liquid, the liquid is mostly supplied by an electric control structure of a valve. However, the opening and closing of the valve requires an external electric drive to realize the opening and closing operation of the valve. Therefore, if the filling gun cannot be closed in time after filling, it is easy to cause liquid to overflow.

[0006] The technical solution of the present invention is implemented as follows: a filling gun feeding structure with an automatic closing structure includes a limit block, the main cross-section of the limit block is a hexagonal structure, and a through hole is opened inside the limit block. There are two limit blocks in total, and a guide rod is inserted into the interior of the two limit blocks, and the main body of the guide rod is a cylindrical structure. A push plate is fixedly connected to the right end face of the guide rod, and the diameter of the push plate is larger than the diameter of the guide rod. The push plate and the guide rod together constitute a pushing structure, and a sealing member A is fixedly connected to the outside of the guide rod, and the diameter of the sealing member A is larger than the diameter of the guide rod, and a spring member is fixedly connected to the right end face of the sealing member A, and the diameter of the spring member is smaller than the diameter of the limit block and the sealing member A:

A sleeve is fixedly connected to the left side of the blocking piece B, and the main body of the sleeve is a hollow tubular structure.

[0008] As a preferred embodiment, a through hole is opened on the outer circumference of the sleeve, and the through hole is used to insert the positioning pin. The diameter of the sleeve is smaller than the diameter of the sealing member B, and the guide rod is located on the inner side of the shell.

[0009] As a preferred embodiment, the main body of the shell is hollow inside and has a two-way through structure on the left and right sides, and a through hole is opened on the top surface of the shell, and a feed pipe is fixedly connected to the inside of the through hole.

[0010] As a preferred embodiment, the feed pipe is connected to the shell, and a connecting plate is fixedly connected to the side of the feed pipe away from the shell, and the main body of the connecting plate is a rectangular plate structure, and a through hole is opened inside the connecting plate, which is a connecting hole.

[0011] As a preferred embodiment, the inner side of the shell is fixedly connected to a support tube, and annular grooves are provided on the inner and outer walls of the support tube, a sealing ring is embedded in the inside of the annular groove, and a support plate is also fixedly connected to the inner side of the shell, and a clamp is sleeved on the outer side of the shell, and a support plate is fixedly connected to the outer side of the clamp, and a positioning bolt is installed inside the support plate.

[0012] After using the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the present invention, by providing a support tube and a support plate fixedly connected to the inner side of the shell, when the guide rod moves, it can not only be guided by the limit block, but also the support tube and the support plate can be used to guide and support the blocking member A fixedly connected to the outer peripheral surface of the guide rod, so that the blocking member A can move more smoothly.

[0014] 2. In the present invention, a spring member is fixedly connected between the sealing member A and the limit block, so that when the liquid is filled and an automatic sealing operation is required, the self-resetting property of the spring member can be utilized to drive the sealing member A to move along the support tube, and the automatic sealing operation of the feed tube can be realized by resetting the sealing member A and the sealing member B, thereby preventing the liquid from overflowing.
