Description

Technical Field

[0001] The invention belongs to the technical field of locking mechanisms, and particularly relates to an air-inflated sealing and safety locking device for a wet granulator. Background Art

[0002] A wet granulator is used to grind wet powder materials into required granules, and can also crush lumpy dry materials into required granules. It is widely used in the pharmaceutical, chemical, and food industries. However, it is not suitable for use with solids, fluids, pastes, or ground materials. Usually, a matching sealing cover is provided at the top of the granulator, and then it is locked by a locking device.

[0003] As Figure 7 and Figure 8 shown, for the air-inflated sealing and locking device of a conventional wet granulator on the market, 1' is a material cylinder, 2' is a cylinder head, 3' is an upper seat for locking the cylinder head, 4' is a lower locking seat, 5' is a cylinder head flange, 6' is a cylinder opening flange, 7' is an air-inflated sealing assembly, 8' is a handle, 9' is a bolt round rod, 10' is a nut, 11' is a washer, and 12' is a proximity switch for in-place detection. This kind of air-inflated sealing and locking device uses a bolt locking handle. The bolt round rod 9' passes through the upper seat 3' for locking the cylinder head, and its lower part is rotatably connected to the lower locking seat 4' through bolts and nuts. By rotating the nut 10' with the handle 8', the upper seat 3' for locking the cylinder head and the lower locking seat 4' are locked. When in use, it is inconvenient to operate. At the same time, the proximity switch is fixed. When not in use, when an object passes by the proximity switch, the device is likely to be accidentally started. Therefore, an air-inflated sealing and safety locking device for a wet granulator is proposed. Summary of the Invention

[0004] The purpose of the invention is to provide an air-inflated sealing and safety locking device for a wet granulator, which can receive the proximity switch into the installation box when not in use, improve the safety of device use, and can prevent the fixed disk and the installation shaft from rotating, preventing people from accidentally touching the rack and causing the rack to rotate. It can also limit the rotation angle of the pull rod, reduce the rotation stroke of the pull rod, facilitate people's subsequent operation of the pull rod, and prevent the pull rod from hitting the material cylinder, thus solving the existing technical problems.

[0005] To solve the above technical problems, the invention is realized through the following technical solutions:

[0014] In the present invention, through the rotational cooperation of the cylinder pull rod and the card rack, the bottom of the card rack can be in abutting connection and locking with the lock groove. Pulling the handle in place can lock the material cylinder and the cylinder head, and dislocation can unlock it, greatly improving the convenience and safety of the locking and unlocking operations of the inflation sealing device.

[0015] In the present invention, through the movable setting of the proximity switch, when the card rack is lowered, the installation shaft can drive the cam to rotate, and then the proximity switch can be driven to retract into the installation box through the first slider, the second slider and the support rod, improving the safety of the device during use.

[0016] In the present invention, through the setting of fixedly connecting the fixed disk to the circumference of the installation shaft, after the clamping block is inserted into the card slot, the fixed disk can be held by the clamping block to prevent the fixed disk and the installation shaft from rotating, and prevent people from accidentally touching the card rack and causing the card rack to rotate.

[0017] In the present invention, through the setting of the protrusion, a first inclined surface is provided on one side of the protrusion, and a second inclined surface is provided at the bottom of the pull rod. When the pull rod is opened, the rotation angle of the pull rod can be limited by the second inclined surface and the first inclined surface, reducing the rotation stroke of the pull rod, facilitating the subsequent operation of the pull rod by people, and preventing the pull rod from colliding with the material cylinder.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. Description of the Drawings

[0036] The locking mechanism includes an upper seat 5 and a lower seat 6, which are respectively fixedly connected to one side of the circumference of the cylinder cover 3 and the material cylinder 1, one side of the lower seat 6 is rotatably connected with a penetrating installation shaft 14, the circumference of the installation shaft 14 is rotatably connected with an H-shaped pull rod 13, and a bracket 16 is rotatably connected between the two sides of the top of the pull rod 13, and a handle is fixedly connected to the top of the bracket 16. A locking groove 10 used in conjunction with the bracket 16 is opened on one side of the top of the upper seat 5. When the cylinder cover 3 needs to be closed, the rotating rod 30 is lifted upward to disengage the block 31 from the bracket 16, and then the pull rod 13 is rotated by the bracket 16. The bottom of the bracket 16 contacts the locking groove 10, and is in a semi-locked state. Then the inflatable sealing assembly 7 begins to be inflated. During inflation, the inflatable sealing assembly expands 7, and the seal between the cylinder cover 3 and the material cylinder 1 is enhanced. A driving assembly for driving the second slider 22 to move is provided on one side of the installation shaft 14.

[0037] Protrusions 11 are provided on both sides of the lower seat 6, and a first inclined surface 12 is provided on one side of the bottom of the protrusion 11, and a second inclined surface 15 used in conjunction with the first inclined surface 12 is provided on one side of the bottom of the pull rod 13.

[0038] The driving component includes a cam 23 which is fixedly connected to one end of the mounting shaft 14 and used in cooperation with the second slider 22. When the mounting shaft 14 rotates, it drives the cam 23 to rotate, thereby lifting the second slider 22.

[0039] On one side of the pull rod 13, there is also an anti-collision mechanism 8 for preventing the accidental rotation of the mounting shaft 14. The anti-collision mechanism 8 includes a fixed disk 28 and a rotating rod 30. The fixed disk 28 is fixedly connected to the circumference of the mounting shaft 14. A plurality of card slots 29 are provided on the circumference of the fixed disk 28. The rotating rod 30 is rotatably connected to one side of the lower seat 6.

By using the latch 31 to engage with the card slot 29 on the fixed disk 28, the fixed disk 28 and the mounting shaft 14 are prevented from rotating, preventing people from accidentally touching the pull rod 13 and causing the pull rod 13 to rotate.

[0040] A baffle 27 is fixedly connected to the top of the second slider 22, and the baffle 27 further improves the protection effect on the proximity switch 20.

[0041] The working process and principle of the technical solution of the present invention are as follows:

[0042] During use, the inflatable sealing component 7 is in an uninflated state. When the cylinder head 3 needs to be closed, the rotating rod 30 is lifted upward to disengage the latch 31 from the card slot 29, and then the pull rod 13 is rotated through the card holder 16. The bottom of the card holder 16 abuts against the locking groove 10, and at this time, it is in a semi-locked state. Subsequently, the proximity switch 20 detects that the pull rod 13 is in place, and the inflatable sealing component 7 starts to be inflated. When inflating, the inflatable sealing component 7 expands, and the seal between the cylinder head 3 and the material cylinder 1 is enhanced. After use, the inflatable sealing component 7 is depressurized, the card holder 16 is toggled back, and the part can return to the initial state;

[0043] While the pull rod 13 rotates back to its original position, it drives the cam 23 to rotate. The cam 23 pushes the second slider 22 upward. The second slider 22 pushes the first slider 19 to slide in the slideway 18 through the support rod 24, thereby pushing the proximity switch 20 into the interior of the mounting box 17. The proximity switch 20 is protected by the mounting box 17 to prevent other foreign objects from approaching the proximity switch 20 and causing the device to start accidentally. While the second slider 22 moves upward, it drives the baffle 27 to block the mounting box 17, further protecting the proximity switch 20. Similarly, while the pull rod 13 rotates upward, the proximity switch 20 is pushed out by the elastic force of the spring 26 for convenient use.
