DETAILED DESCRIPTION

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0031] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 4 As shown, a flexible powder valve device and an opening and closing method at a dynamic and static connection provided by an embodiment of the present invention include a curtain 1, an upper buckle 2 and a lower buckle 3. The top of the surface of the curtain 1 is used in conjunction with the surface of the upper buckle 2, and the bottom of the surface of the curtain 1 is used in conjunction with the surface of the lower buckle 3. A bag-type air spring 4 is arranged inside the curtain 1. The top of the bag-type air spring 4 is connected to a vent pipe 5. The top of the surface of the vent pipe 5 is fixedly connected to a first fixed disk 6. The first fixed disk 6 is fixedly connected to a first fixed rod 7 on all sides of the surface. The first fixed rod 7 is fixedly connected to the inner wall of the upper buckle 2 on one side away from the first fixed disk 6. The bottom of the bag-type air spring 4 is fixedly connected to a limiting mechanism 8. The bottom of the limiting mechanism 8 penetrates the bag-type air spring 4 and extends to the bottom of the bag-type air spring 4. The bottom of the limiting mechanism 8 is fixedly connected to a second fixed disk 9. The second fixed disk 9 is fixedly connected to a second fixed rod 10 on all sides of the surface. The second fixed rod 10 is fixedly connected to the inner wall of the lower buckle 3 on one side away from the second fixed disk 9.

[0033] refer to Figure 1 and Figure 2The limiting mechanism 8 includes a limiting rod 801, the bottom of which is fixedly connected to the top of the second fixed plate 9, a sealing plate 802 is sleeved on the top of the surface of the limiting rod 801, the top of the sealing plate 802 is fixedly connected to the bottom of the bag air spring 4, the top of the limiting rod 801 passes through the bag air spring 4 and extends to the interior of the bag air spring 4, a limiting tube 803 is sleeved on the top of the surface of the limiting rod 801, and the bottom of the limiting tube 803 is fixedly connected to the bottom of the inner wall of the bag air spring 4.

[0034] By adopting the above solution, by setting the limiting mechanism 8, the bag-type air spring 4 can move vertically up and down when injecting and extracting air from the bag-type air spring 4, avoiding the bag-type air spring 4 moving up and down and causing loose sealing, thereby improving the sealing of the equipment.

[0035] refer to Figure 3 The top of the limiting rod 801 is fixedly connected to the limiting block 11, the surface of the limiting block 11 is movably connected to the inner wall of the limiting tube 803, the top of the limiting block 11 is fixedly connected to the return spring 12, and the top of the return spring 12 is fixedly connected to the top of the inner wall of the limiting tube 803.

[0036] The above scheme is adopted: by setting the limit block 11 and the return spring 12, the stability of the limit tube 803 moving up and down can be effectively increased to avoid the shaking of the limit tube 803. The return spring 12 can facilitate the contraction of the bag-type air spring 4 and facilitate the discharge of materials.

[0037] refer to Figure 4 A slope is provided at the bottom of the sealing plate 802 , and a sealing ring 13 is fixedly connected to the slope. The bottom of the sealing ring 13 cooperates with the bottom of the inner wall of the lower buckle 3 .

[0038] The above solution is adopted: by providing a slope and a sealing ring 13, the slope can facilitate the powder to fall downward through the lower buckle 3 and the discharge port 15, and the sealing ring 13 can facilitate the sealing between the sealing plate 802 and the lower buckle 3, which is convenient for users to use.

[0039] refer to Figure 1 The first fixing plate 6 and the first fixing rod 7 are located inside the upper buckle 2 , and the gap between the first fixing plate 6 , the first fixing rod 7 and the upper buckle 2 forms a feed port 14 .

[0040] The above scheme is adopted: by setting the feed port 14, it is convenient for materials to enter from the feed port 14, and at the same time, the first fixed rod 7 and the first fixed plate 6 can limit the bottom ventilation pipe 5 and the bag-type air spring 4, thereby increasing the stability of the bag-type air spring 4.

[0041] refer to Figure 1 and Figure 4The second fixing plate 9 and the second fixing rod 10 are located inside the lower buckle 3 , and the gap between the second fixing plate 9 , the second fixing rod 10 and the lower buckle 3 forms a discharge port 15 .

[0042] By adopting the above solution, by providing the discharge port 15, when the sealing plate 802 and the sealing ring 13 are separated from the lower buckle 3, the powder can fall downward through the gap between the sealing ring 13 and the lower buckle 3, and thus be transported to the equipment below.

[0043] refer to Figure 1 Screws 16 are arranged around the bottom of the upper buckle 2 and around the top of the lower buckle 3, and the threaded ends of the screws 16 penetrate the upper buckle 2 and the lower buckle 3 respectively and extend their surfaces.

[0044] By adopting the above solution, the screws 16 can be provided to conveniently connect the connecting device to the top and bottom equipment, thereby increasing its sealing performance, facilitating the transportation of powder materials, and improving the stability of the device.

[0045] refer to Figure 1 , the opening and closing methods of the device include:

[0046] Step 1: The inner bag is de-aired, and the air in the bag-type air spring 4 is discharged through the vent pipe 5, so that the sealing plate 802 is separated from the lower buckle 3;

[0047] Step 2: When the sealing plate 802 is separated from the lower buckle 3 and the material leaks out through the discharge port 15, the material enters the gap between the curtain fabric 1 and the bag-type air spring 4 through the feed port 14, and then feeds into the equipment through the discharge port 15;

[0048] Step 3: When the feeding is completed, air is injected into the bag-type air spring 4 through the vent pipe 5, so that the bag-type air spring 4 drives the sealing plate 802 to move downward;

[0049] Step 4: When the sealing plate 802 contacts the inner wall of the lower buckle 3, the input of materials is stopped.

[0050] By adopting the above scheme, through the opening and closing method of the flexible powder valve device at the dynamic and static connection, the vibrating granulator can be transported with materials in real time when the vibrating granulator is working, and the feed port 14 of the vibrating granulator can be sealed at the same time.

[0051] Working principle of the present invention:

[0052] When in use, when the user needs to convey materials to the vibration granulator, the material enters between the curtain 1 and the bag air spring 4 through the feed port 14, and the air in the bag air spring 4 is discharged. The bag air spring 4 contracts and drives the sealing plate 802 to move upward, and the sealing plate 802 drives the sealing ring 13 to separate from the surface of the lower buckle 3. The sealing plate 802 slides on the surface of the limit rod 801, so that the limit block 11 slides on the inner wall of the limit tube 803, and the material leaks downward through the gap between the sealing plate 802 and the lower buckle 3. When the material transmission is completed, the inside of the bag air spring 4 is inflated, and the bag air spring 4 pushes the sealing plate 802 to move downward, and the sealing plate 802 drives the sealing ring 13 to contact the lower buckle 3. When the sealing plate 802 is sealed with the lower buckle 3 through the sealing ring 13, the sealing of the discharge port 15 is completed. At the same time, since the curtain 1 and the bag air spring 4 are both flexible materials, they can have a certain amount of shaking, which meets the demand for continuous feeding of the vibration granulator.

[0053] In summary: the flexible powder valve device and opening and closing method at the dynamic and static connection, by arranging a curtain 1, an upper buckle 2, a lower buckle 3, a bag air spring 4, a vent pipe 5, a first fixed plate 6, a first fixed rod 7, a limit mechanism 8, a limit rod 801, a sealing plate 802, a limit pipe 803, a second fixed plate 9, a second fixed rod 10, a limit block 11, a return spring 12, a sealing ring 13, a feed port 14, a discharge port 15 and a screw 16, solves the problem that the existing vibration granulator shakes as a whole during use, and the vibration granulator needs to be stopped for feeding when feeding, which reduces the working efficiency and is not conducive to use.
