Description

Technical Field

[0001] The utility model relates to the technical field of a container feeding port structure, in particular to a flip-cover automatic feeding port structure of a normal pressure container. Background Art

[0002] With the development of food processing, more and more food processing has been automated. In order to adapt to the production process of automation and intelligence, the original food processing equipment needs to be improved.

[0003] Cooking containers, frying containers, and mixing containers are often used in the food processing industry. These types of containers have now been automated in the production and processing process. However, the feeding of these containers still requires manual assistance or even manual operation. For example, the feeding port needs to be opened manually, and then the feeding device can automatically feed or directly feed manually. After the feeding is completed, the feeding port is manually closed. The reason is that the opening and closing operations of the feeding port must be relatively fast to match the rhythm of the feeding device. If the opening and closing of the cover is relatively slow, and the efficiency is equivalent to that of manual opening and closing, the manufacturer has no motivation to make modifications. In addition, the existing automatic opening and closing device for the feeding port, due to the structural reasons of the opening and closing device, and the opening and closing device driving the feeding port to open and close, occupies a large space around the feeding port, thereby affecting the setting of the automatic feeding device and the connection with the feeding port. Due to the above reasons, the feeding cannot be automated at present.

[0004] The feed port structure of an atmospheric pressure vessel is different from that of a pressure vessel. The applicant's technicians have improved the feed port structure of the atmospheric pressure vessel to achieve automation. Furthermore, the applicant also submitted another improved structure for the feed port of a pressure vessel on the same day. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a flip-top automatic feeding port structure for a normal pressure container, wherein the opening and closing driving piston is arranged on one side of the feeding pipe, and the end of the piston rod A of the opening and closing driving piston is connected to the driving rod arranged on the top of the cover plate on one side of the swing axis, the stroke of the piston rod A can be effectively reduced under the same swing stroke of the cover plate, which not only facilitates the rapid opening and closing of the cover plate and increases the opening angle of the cover plate, but also enables the opening and closing driving piston to be within the range of the feeding pipe and the piston rod A to always be within the opening and closing swing range of the cover plate, thereby saving the activity space required for the feeding port of the normal pressure container.

[0006] The technical solution adopted by this utility model is:

One side of the feeding pipe is also provided with an opening and closing driving piston of the cover plate, the opening and closing driving piston is swingably connected to the normal pressure container or the feeding pipe, the piston rod A end of the opening and closing driving piston is connected to the driving rod provided on the top of the cover plate on one side of the swing shaft, the outer wall of the feeding pipe is connected with a lock hook driving piston at a position below the lock hook, the lock hook driving piston is swingably connected to the feeding pipe, and the piston rod B end of the lock hook driving piston is swingably connected to the lock hook.

A limiting driving piston is fixedly provided on the outer side wall of the feeding tube corresponding to the side where the protrusion is located, and a limiting rod matching the limiting hole is fixed on the end of the piston rod C of the limiting driving piston. When the piston rod C retracts the limiting driving piston to the maximum stroke, the limiting rod is separated from the limiting hole of the protrusion.

[0013] A further improvement of the present invention is that an annular groove is coaxially provided on the top of the annular flange A, and a sealing strip is placed in the annular groove. The cross-section of the sealing strip is an inverted "U"-shaped structure, and the top height of the sealing strip in its natural state is higher than the top surface height of the annular flange A.

[0016] A further improvement of the present invention is that a hand pull ring is fixedly provided on one side of the top of the cover plate away from the swing axis.

[0017] The beneficial effects of the present invention are:

[0018] First, the flip-top automatic feeding port structure of the atmospheric pressure container of the present invention, by arranging the opening and closing driving piston on one side of the feeding pipe, and connecting the end of the piston rod A of the opening and closing driving piston to the driving rod arranged on the top of the cover plate on one side of the swing axis, can effectively reduce the stroke of the piston rod A under the same swing stroke of the cover plate, which not only facilitates the rapid opening and closing of the cover plate and increases the opening angle of the cover plate, but also enables the opening and closing driving piston to be within the range of the feeding pipe and the piston rod A to always be within the opening and closing swing range of the cover plate, thereby saving the activity space required for the feeding port of the atmospheric pressure container.

[0019] Second, the flip-type automatic feeding port structure of the atmospheric pressure container of the present invention can ensure that the cover is in a closed state when it is closed with the feeding pipe through the action of the locking hook, and press down the sealing strip to isolate the feeding port from the outside air.

[0027] Combine Figures 1 to 3 It can be seen that the flip-type automatic feeding port structure of the atmospheric pressure container includes a feeding pipe 1 of the atmospheric pressure container, and the top of the feeding pipe 1 is provided with an openable and closable cover plate 2, and one side edge of the cover plate 2 is swingably connected to the corresponding edge of the top of the feeding pipe 1 through a swing shaft 11, and the outer tube wall of the feeding pipe 1 is provided with a lock hook 7 on the side facing away from the swing shaft 11 for closing and fixing the cover plate 2 and the feeding pipe 1. One side of the feeding pipe 1 is also provided with an opening and closing drive piston 8 of the cover plate 2, and the opening and closing drive piston 8 is swingably connected to the atmospheric pressure container or the feeding pipe 1, and the piston rod A end of the opening and closing drive piston 8 is connected to the drive rod 13 provided on the top of the cover plate 2 on the side of the swing shaft 11, and the outer wall of the feeding pipe 1 is located below the lock hook 7. The lock hook drive piston 9 is swingably connected to the feeding pipe 1, and the piston rod B end of the lock hook drive piston 9 is swingably connected to the lock hook 7.

[0028] The locking hook 7 is a "C"-shaped structure, and the lower end of the locking hook 7 is swingably connected to the feeding pipe 1 through the connecting seat C10. When the piston rod B extends the locking hook to drive the piston 9 to the maximum stroke, the upper end of the locking hook 7 will be pressed and fixed to the corresponding edge of the cover plate 2 at the pipe mouth of the feeding pipe 1. When the piston rod B retracts the locking hook to drive the piston 9 to the maximum stroke, the locking hook 7 is separated from the cover plate 2 and swings to the outside of the swinging trajectory of the cover plate 2.

[0029] The lower end of the locking hook 7 is swiveled connected to a swing seat C10 fixed to the outer wall of the feeding pipe 1 , and the locking hook driving piston 9 is swiveled connected to a swing seat E15 fixed to the outer wall of the feeding pipe 1 .

[0030] A protrusion 14 is also provided in the middle of one side wall of the locking hook 7, and a limiting hole is provided on the end face of the protrusion 14 facing away from the locking hook 7. A limiting driving piston 22 is fixedly provided on the outer side wall of the feeding pipe 1 corresponding to the side where the protrusion 14 is located. A limiting rod matching the limiting hole is fixed to the end of the piston rod C of the limiting driving piston 22. When the piston rod C retracts the limiting driving piston 22 to the maximum stroke, the limiting rod is separated from the limiting hole of the protrusion 14. When the piston rod C extends out of the limiting driving piston 22 to the maximum stroke, the end of the limiting rod extends into the limiting hole of the protrusion 14.

[0031] The limit driving piston 22 is fixedly connected to the wall of the feeding pipe 1 through the connecting plate 16 .

[0032] The swing shaft 11 is respectively connected to the axial holes of the swing seat A3 penetrating the outer wall of the feeding pipe 1 and the swing seat B4 fixed to the edge of the cover plate 2. The swing seat A3 and the swing seat B4 are swingably connected through the swing shaft 11.

[0033] An annular flange A5 is coaxially provided on the edge of the top pipe opening of the feeding pipe 1, and an annular flange B6 matching the annular flange A5 is coaxially provided on the edge of the cover plate 2. When the locking hook 7 fixes the closed cover plate 2 and the feeding pipe 1, the locking hook 7 contacts the top of the corresponding position of the annular flange B6, pressing the annular flange B6 to be fixed to the annular flange A5.

[0034] An annular groove 18 is coaxially provided at the top of the annular flange A5, and a sealing strip 19 is placed in the annular groove 18. The cross section of the sealing strip 19 is an inverted "U"-shaped structure, and the top height of the sealing strip 19 in its natural state is higher than the top surface height of the annular flange A5.

[0035] The bottom of the annular groove 18 is also provided with an annular plate 20 that matches the bottom of the annular groove 18. The bottom of the annular flange A5 is concentrically and evenly distributed with multiple screw holes 21 corresponding to the position of the annular groove 18. The adjusting bolt is adjustably fixed to the annular flange A5 through the screw hole 21, and the top of the adjusting bolt adjusts the height of the annular plate 20.

[0036] When the piston rod A extends the opening and closing driving piston 8 to the maximum stroke, the angle between the cover of the cover plate 2 and the plane where the top opening of the feeding pipe 1 is located is an obtuse angle or a right angle. When the piston rod A retracts the opening and closing driving piston 8 to the maximum stroke, the cover plate 2 is just closed with the top opening of the feeding pipe 1.

[0037] The opening and closing driving piston 8 is swingably connected to the normal pressure container or the feeding pipe 1 through the swing seat D12.

[0038] A hand pull ring 17 is fixedly provided on the top of the cover plate 2 at one side away from the swing shaft 11 .

[0039] The process of using the flip-type automatic feeding port structure of the atmospheric pressure container is as follows:

[0040] When the feeding pipe of the atmospheric pressure container needs to be fed, the piston rod C retracts the limit driving piston 22 to the maximum stroke, at which time the limit rod is separated from the limit hole of the protrusion 14; then the piston rod B retracts the lock hook driving piston 9 to the maximum stroke, at which time the lock hook 7 swings around the swing seat C10 to separate from the cover plate 2 and is located outside the swing trajectory of the cover plate 2; then the piston rod A extends the opening and closing driving piston 8 to the maximum stroke, at which time the driving rod 13 drives the cover plate 2 to swing around the swing axis 11 until the opening between the cover plate 2 and the top opening of the feeding pipe 1 is maximum.

[0041] When the feeding of the feeding pipe of the atmospheric pressure container is completed, the piston rod A retracts the opening and closing driving piston 8 to the maximum stroke. At this time, the driving rod 13 drives the cover plate 2 to swing around the swing axis 11 until the cover plate 2 and the top opening of the feeding pipe 1 are closed; then the piston rod B extends the lock hook to drive the piston 9 to the maximum stroke. At this time, the lock hook 7 swings around the swing seat C10 to press and fix the top of the annular flange B6 of the cover plate 2 to the top of the annular flange A5 of the feeding pipe 1; then the piston rod C extends the limit driving piston 22 to the maximum stroke. At this time, the limit rod extends into the limit hole of the protrusion 14 to realize limit locking.

[0042] The sealing strip 19 within the annular groove 18 formed on the top surface of the annular flange A5 seals the air inside the atmospheric pressure container from the outside world. Over time, the sealing strip 19 deforms downward or wears due to prolonged pressure. This causes the deformed or worn sealing strip 19 to no longer provide an effective seal when the annular flange B6 and the annular flange A5 are closed. At this point, the annular plate 20 within the annular groove 18 is lifted by adjusting the bolts, thereby also lifting the sealing strip 19. This allows the sealing strip 19 to continue to provide a seal and extends its service life.
