DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0035] The following is combined with Figure 1 To Attachment Fig. 9 And specific embodiments describe the present invention in detail.

[0036] like Figure 1-9As shown, the utility model provides a flange connection device, which can be docked with different types of flange ball valves 4, avoiding repeated replacement of tooling, and achieving improved efficiency and quality. The flange connection device includes a flange connector 1 and at least two clamping mechanisms 2, wherein the flange connector 1 has an upper docking plate 11, and the upper surface of the upper docking plate 11 is formed with a docking surface, and the docking surface is used for contact and connection with the flange ball valve 4 of the connected part; at least two clamping mechanisms 2 are fixed on the side wall of the flange connector 1 at circumferential intervals, and the clamping mechanism 2 is used to press the flange ball valve 4 onto the flange connector 1 to achieve a tight connection between the two; the clamping mechanism 2 includes a driving assembly 21, a locking head 22 and a pressing piece 23, and the locking head 22 and the pressing piece 23 are detachably fixedly connected, that is, the pressing piece 23 can be relatively easily removed from the locking head 22. After disassembly, the clamping member 23 can be relatively easily assembled on the locking head 22. The locking head 22 is a common joint that can be connected to clamping members 23 of different structures. This application does not specifically limit the detachable connection between the locking head 22 and the clamping member 23. For example, the drive assembly 21 is connected to the locking head 22, and the locking head 22 is driven to move to drive the clamping member 23 downward to press on the flange ball valve 4 of the connected member, thereby achieving a tight connection between the flange connector 1 and the connected member, and the lower end of the flange connector 1 is connected to a discharge pipe, through which the material is transported to the use end. It can be known that different packaging barrels are equipped with different flange ball valves 4, and the structures of different flange ball valves 4 are different. In the related art, before unloading, the ball valves on the packaging barrels of different suppliers need to be replaced with the same ball valve in order to achieve the docking of the packaging barrels with the connecting device in the prior art. This process is not only cumbersome but also has low connection efficiency. However, the present application realizes that when different packaging barrels are replaced, different clamping parts 23 are configured to adapt to the corresponding flange ball valves 4 through the detachable connection of the clamping head 23. Before docking, the operator only needs to install the clamping parts 23 that are compatible with the type of flange ball valve 4 on the packaging barrel. The whole operation process is simple, and there is no need to replace the ball valves on the packaging barrels provided by the supplier, thereby improving the connection efficiency.

[0037] In some embodiments, in order to enable the flange connection device to adapt to flange ball valves of different sizes, the flange connection device also includes a conversion disk 3 detachably connected to the docking surface, and the upper end surface of the conversion disk 3 is formed with a conversion surface, and the conversion surface can also be used to contact and connect with the flange ball valve 4 of the connected part. The present application also does not limit the detachable connection method of the conversion disk 4 and the upper docking disk 11. Optionally, a countersunk hole is provided on the conversion disk 4, and a threaded hole is provided on the upper docking disk 11. The two are fixedly connected by passing the hexagon socket bolt through the countersunk hole and screwing in the threaded hole. It should be noted that the size of the adapter disk 3 and the upper docking disk 11 is different. For example, the diameter of the upper docking disk 11 is smaller, while the diameter of the conversion disk 3 is larger. The conversion disk 3 is used to adapt to large-sized flange ball valves, and the upper docking disk is used to adapt to small-sized flange ball valves. In actual use, according to the size of the flange ball valve, the corresponding conversion disk 3 can be added or reduced on the upper docking disk 11 to achieve convenient and fast connection. In other words, the present application does not limit the number of conversion disks 3, and multiple conversion disks 3 of different sizes can be designed according to actual needs, so as to achieve flange ball valves that are suitable for all different types of packaging barrels.

[0038] For example, there are two types of flange ball valves for packaging barrels, one is a DN50 flange ball valve, and the other is a DN80 flange ball valve. The DN50 flange ball valve is smaller in size and can be installed and docked using only the upper docking plate. However, the DN80 flange ball valve is larger in size and the upper docking plate is no longer suitable for connecting the two. In this case, a larger conversion plate 3 can be installed on the upper docking plate, and then the DN80 flange ball valve can be installed on the upper docking plate to meet the installation requirements.

[0039] In a specific embodiment, the conversion disk 3 is provided with a through hole along the central axis, and the through holes are respectively connected to the flange connector 1 and the connected part. Correspondingly, a connecting hole is also provided on the upper docking disk 11, and the connecting hole is directly opposite to the through hole and is connected. The inner diameter of the through hole is smaller than the outer diameter of the upper docking disk 11, so as to realize the upper and lower stacking and sealing connection between the upper docking disk 11 and the conversion disk 3; of course, the size of the conversion disk 3 can be specifically set according to the size of the loading and unloading holes of the flange ball valve, and there is no sole limitation on this. For example, the conversion disk 3 and the upper docking disk 11 can also be connected by a set of sets.

[0040] Preferably, the flange connector 1, the conversion disk 3, the clamping piece 23, etc. are all made of stainless steel, which is resistant to corrosion and temperature, has high hardness, and can meet the needs of various production environments. The clamping piece 23 can be quickly replaced, thereby solving the use of raw material packaging barrels from different suppliers during the production process, saving the operation time of replacing the same ball valve, and the connection efficiency can be increased by at least 2-3 times, reducing the risk of material residue caused by installing a ball valve on the packaging barrel, and improving quality and safety operations.

[0041] In some embodiments, see Figure 1 , Figure 4 , Figure 5 , Figure 6 The flange connection device is equipped with multiple clamping members 23 with different structures. Some clamping members 23 are installed on the clamping mechanism 2, and other clamping members 23 are used as spare clamping members, which can be replaced at any time when needed; one of the clamping members 23 is connected to each clamping mechanism 2. For example, there are three clamping mechanisms 2, and the structures of the three clamping members on the three clamping mechanisms can be the same or different. The specific needs are determined according to the obstacles on the flange ball valve 4. The clamping member 23 needs to be pressed down to the plane of the flange ball valve 4, so it is necessary to avoid the obstacles on it, and the clamping member 23 in the present application is designed according to the type and structure of the flange ball valve.

[0042] In some embodiments, a first connecting portion (not shown in the figure) is provided on the locking head 22, and a second connecting portion 231 is respectively provided on the plurality of clamping members 23. The first connecting portion and the second connecting portion 231 are matched and connected. The first connecting portion may be a threaded hole, and the second connecting portion 231 may be a through hole. In this case, the two can be connected by screws or bolts.

[0043] In some embodiments, see Figure 1 A bracket 24 corresponding to the clamping mechanism 2 is fixed on the outer wall of the flange connector 1, and the lower end of the bracket 24 extends in a direction away from the outer wall of the flange connector 1. The driving assembly 21 includes a driving member 211 fixed at the lower end of the bracket 24 and a fisheye joint 212 connected to the driving end of the driving member 211. The driving member 211 can be a cylinder, an oil cylinder, etc.; the locking head 22 includes a first rotating part 221 and a second rotating part 222 connected to each other, and the first rotating part 221 and the upper end of the bracket 24 are connected through a first hinge shaft 223 is hingedly connected, and the second rotating part 222 is hingedly connected to the fisheye joint 212 through the second hinge shaft 224. When docking, the driving member 211 drives the fisheye joint 212 to move upward, thereby driving the locking head 22 to rotate inward around the first hinge shaft 223 until the clamping member 23 is pressed against the flange ball valve. When undocking, the driving member 211 drives the fisheye joint 212 to move downward, thereby driving the locking head 22 to rotate outward around the first hinge shaft 223 until the clamping member 23 leaves the flange ball valve.

[0044] In some embodiments, see Figure 3 The locking head 22 has an inverted L-shaped structure, that is, the first rotating part 221 is a vertical part, the second rotating part 222 is a horizontal part, and the first rotating part 221 can only rotate around the first hinge axis 223, while the second rotating part 222 can rotate around the second hinge axis 224, and can also move up or down with the fisheye joint 212. The first connecting part is arranged on the upper plane of the locking head 22, and the first connecting part is away from the second hinge axis 224. Optionally, the first connecting part is a threaded hole, and the second connecting part 231 is a through hole, and the two are fixedly connected by bolts or screws.

[0045] In some embodiments, the clamping member 23 includes a connecting block 232 detachably connected to the locking head 22 and at least one roller 233 rotatably arranged on the connecting block 232, the roller 233 is arranged at the free end of the connecting block 232, and the lower end of the roller 233 protrudes from the lower bottom surface of the connecting block 232 to ensure that it is not the connecting block 232 that contacts the upper plane of the flange ball valve 4, but the roller 233 that contacts the upper plane of the flange ball valve 4, and the end with the roller 233 is used to press the smooth surface of the flange ball valve 4. The design of the roller 233 can reduce the hard friction caused by the direct connection between metal and metal surfaces, and can avoid surface wear caused by long-term use.

[0046] In one embodiment, see Figure 4 The connecting block 232 of the pressing piece 23 is a rectangular flat block, and one or more rollers 233 are embedded in the free end of the rectangular flat block, and the center of the roller 233 and the body center of the rectangular flat block are on the same plane. The diameter of the roller 233 is greater than the thickness of the rectangular flat block to ensure that only the roller 233 contacts the upper plane of the flange ball valve 4. The design of the roller 233 can reduce the hard contact between the rectangular flat block and the flange ball valve, thereby reducing wear.

[0047] In another embodiment, see Figure 5 The connecting block 232 of the clamping member 23 is a semi-convex block, that is, a special-shaped block, the purpose of which is to enable the connecting block to avoid obstacles (such as reinforcing ribs, etc.) on the flange ball valve 4, so as to avoid obstacles and satisfy the function of pressing the flange ball valve. Of course, in other embodiments, the shape of the connecting block 232 can be designed according to the position of the obstacle, which can not only achieve the function of pressing the flange ball valve, but also avoid obstacles, which belongs to the protection scope of this application.

[0048] In another embodiment, see Figure 6 The connecting block 232 of the clamping piece 23 is a concave structure, and the rollers 233 are arranged on the two legs of the concave structure. The clamping piece 23 is suitable for flange ball valves 4 with large obstacles and close distances, such as 8-hole special flange ball valves. There are 8-hole screw buckles on the flange surface, and nut obstacles are evenly distributed on the entire flange surface. The clamping piece 23 can be used to wrap the nut and press on both sides of the obstacle at the same time, thereby improving the clamping effect.

[0049] It is worth noting that the specific shape of the connection block 232 of the present application is designed according to the structure of the flange ball valve 4 to be connected. The more types of flange ball valves 4 there are, the more connection blocks 232 may need to be spared. The above three embodiments are only examples and are not limited to this.

[0050] In some embodiments, see Figures 7 to 9The flange connector 1 also has a lower docking plate 12, which is connected to the material discharge pipe. The material discharge pipe is arranged on the movable plate 5, and the movable plate 5 can be lifted and lowered on the base bracket 64 through a lifting component, so that the packaging barrel 7 is first placed on the barrel rack, and then the flange connector 1 is raised by the lifting component to dock with the flange ball valve at the lower end of the packaging barrel 7, making the connection process more convenient.

[0051] In one embodiment, the lifting assembly includes a lifting base plate 61, a turbine 62 disposed on the lifting base plate 61, and a screw 63 cooperating with the turbine 62, the lower end of the screw 63 is fixed to a base bracket 64, a hand wheel 65 is disposed on the turbine 62, and the hand wheel 65 is turned to move the turbine 62 and the lifting base plate 61 up and down along the screw 63; the movable plate 5 is movably disposed on the lifting base plate 61, thereby realizing the lifting of the movable plate 5. The lifting assembly described above in this application is only one embodiment, and any lifting assembly that can realize the lifting function of the flange connector 1 belongs to the protection scope of this application.

[0052] In some embodiments, see Figure 7 , two first guide rails 66 are arranged on the lifting bottom plate 61 along the first direction, and two second guide rails 67 are arranged along the second direction. The end of the second guide rail 64 is slidably connected to the first guide rail 66 through the first slider. The lower end of the movable plate 5 is provided with a second slider, and the second slider is slidably connected to the second guide rail 67. The first direction and the second direction are arranged vertically. In this application, the first direction is described as the X-axis and the second direction is described as the Y-axis. In other words, the flange connector 1 can move in the X-axis direction and the Y-axis direction to achieve the position adjustment of the flange connector 1, so as to more accurately dock the flange ball valve on the packaging barrel.

[0053] In some embodiments, a support column 68 is provided on the movable plate 5 at the periphery of the flange connector, a connecting rod 69 is fixed to the outer wall of the flange connector 1, a sleeve is provided at the end of the connecting rod 69, and the sleeve is sleeved on the support column 68, thereby supporting the flange connector 1.

[0054] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model.
