Description

Technical Field

[0001] This invention relates to the field of mixer technology, and more specifically, to a hopper cover locking structure for a mixer. Background Technology

[0002] In modern industrial production, automatic lifting mixers are widely used for the uniform mixing of various materials to improve production efficiency and ensure mixing quality. During operation, a hopper filled with material is placed in the mixer's frame, which automatically lifts and clamps the hopper to ensure stability. The mixer then rotates along its mixing axis, holding the hopper in place. A reliable automatic locking mechanism is essential in this process to securely fix the hopper lid to the hopper, preventing material leakage during mixing and meeting mixing requirements. However, current automatic hopper lid locking mechanisms have poor locking effectiveness, affecting the mixer's mixing performance.

[0003] According to patent document CN202120244071.1, this utility model relates to a pharmaceutical mixer hopper that is easy to clean, belonging to the field of pharmaceutical equipment technology. This easy-to-clean pharmaceutical mixer hopper includes a frame, a hopper body, a sealing cover, a locking clamp, a valve plate, an upper sleeve, a lower sleeve, a hook, a brake caster, and a locking half-ring. The hopper body is fixedly installed inside the frame. A sealing cover is fixedly installed at the upper inlet of the hopper body via a locking clamp. An upper sleeve is provided at the lower outlet of the hopper body. A lower sleeve is provided at the lower part of the upper sleeve. A hook is fixedly installed on the outer side of the lower sleeve. Locking half-rings are movably hinged to both sides of the hook.

Springs 4213 are fitted onto the outer walls of the front and rear fixing rods 4212 that are close to each other. Two adjacent fixing rods 4212 are far from the fixing blocks 4208. A double-hole slide plate 4214 is fitted on one side of the outer wall of 11. A toothed block 4215 is fixedly connected to the bottom of the double-hole slide plate 4214. The outer wall of the toothed block 4215 is movably connected to the outer wall of the gear 4105. The outer wall of the rack 4210 is meshed with the outer wall of the gear 4105. By starting the stepper motor 34, the rotating shaft 33 drives the threaded rod 35 to rotate. The rotation of the threaded rod 35 causes the connecting shaft 306 to rotate, thereby driving the bevel gear 307 to rotate. Because conical tooth 307 meshes with the outer wall of conical tooth 411, it drives connecting rod 412 to rotate on the inner wall of fixed sleeve 413, which in turn causes conical tooth 414 to rotate. The rotation of conical tooth 414 then drives conical tooth 415 to rotate, causing connecting rod 416 to rotate on the inner wall of fixed sleeve 4100 and driving conical tooth 417 to rotate. The rotation of conical tooth 417 then drives conical tooth 418 to rotate, thus connecting... Rod 3 419 rotates on the inner wall of fixed sleeve 3 410, driving bevel gear 7 4101 to rotate. The rotation of bevel gear 7 4101 drives bevel gear 8 4102 to rotate, causing connecting rod 4103 to rotate on the inner wall of fixed sleeve 4104. This, in turn, causes gear 1 4105 to rotate. The outer wall of gear 1 4105 meshes with the outer wall of connecting plate 2 4206, thereby moving connecting plate 2 4206. Gear 1 4105 drives the connecting plate... When gear 4206 moves to both ends, the teeth of gear 4105 will contact the outer wall of the tooth block 4215, causing the tooth block 4215 to move and the double-hole slide plate 4214 to slide on the outer wall of the fixed rod 4212, thus compressing the second spring 4213. When the teeth of gear 4105 pass the outer wall of the tooth block 4215, the second spring 4213 pushes the double-hole slide plate 4214, causing the tooth block 4215 to return to the tooth groove of gear 4105, thereby achieving gear limiting. The positioning effect is achieved by moving rack two 4210, which in turn moves connecting plate two 4206, causing rack one 4205 to move. The movement of connecting plate two 4206, in turn, moves connecting plate three 4207, causing the convex block 4209 to slide on the inner wall of the dovetail groove 4208. This improves the stability of connecting plate two 4206 during movement. Furthermore, the outer wall of rack one 4205 meshes with the outer wall of gear two 4204, so when rack one 4205 moves, it drives gear two 4204 to rotate.The rotation of gear 4204 drives the connecting shaft 4202 to rotate within the support sleeve 4203, which in turn causes the worm gear 420 to rotate. The outer wall of the worm gear 420 meshes with the outer wall of the half gear 424, causing the half gear 424 to rotate. This rotation of the half gear 424 then causes the limiting rod 423 to rotate within the perforated support arc-shaped plate 422, improving the stability of the half gear 424 during movement. The rotation of the half gear 424 also causes the movable plate 425 to flip, thereby causing the trapezoidal locking block 427 to flip and release the limiting effect on the modular hybrid structure 5. The rotation of the threaded rod 35 causes the slider 37 to move on the outer wall of the threaded rod 35. The movement of the slider 37 causes the front limiting block 30 to slide on the inner wall of the rectangular guide hole 36, which in turn causes the front connecting plate 301 to move. The movement of the front connecting plate 301 causes the front fixing plate 302 to move, which in turn causes the front arc plate 303 to move the hopper cover 304. The movement of the hopper cover 304 causes the rear fixing plate 302, connecting plate 301, and limiting block 30 to move, causing the sliding sleeve 39 to slide on the outer wall of the sliding rod 38, thus raising the hopper cover. The stability of 304 during movement is achieved by moving the hopper cover 304, which in turn drives the modular mixing structure 5 to lift or lower. When the modular mixing structure 5 is lifted, it simultaneously engages a limiting action, opening the feed inlet at the top of the hopper 2 for easy loading. When the modular mixing structure 5 is lowered, the reverse rotation of the conical tooth 307 further drives the half-gear 424 to rotate, ensuring the movable plate 425 and the trapezoidal locking block 427 are horizontal. When the fixing ring 3041 in the hopper cover 304 drives the modular mixing... When the modular hybrid structure 5 descends and contacts the inclined surface of the trapezoidal locking block 427, it will push the trapezoidal locking block 427, causing the rectangular guide rod 426 to slide on the inner wall of the rectangular through hole. Simultaneously, it will push the circular guide rod 428 to slide on the inner wall of the circular movable hole, compressing the spring 429. When the fixing ring 3041 moves the modular hybrid structure 5 to below the trapezoidal locking block 427, and the fixing ring 3041 stops at the top of the limiting sealing ring 305, the spring 429 will push the trapezoidal locking block 427 to lock onto the top of the modular hybrid structure 5, achieving a limiting effect.

[0035] like Figure 10As shown, the modular hybrid structure 5 includes a sealing cover 51. The top of the sealing cover 51 is movably connected to the bottom of two trapezoidal blocks 427, and the bottom of the sealing cover 51 is movably connected to the top of a fixing ring 3041. A fixing disk 52 is fixedly connected to the center of the bottom of the sealing cover 51. An insert ring 53 is fixedly connected to the bottom of the sealing cover 51 away from the center point. The outer wall of the insert ring 53 is movably connected to the inner wall of an annular groove 3042. The outer wall of the fixing disk 52 is movably connected to the inner wall of the fixing ring 3041. Multiple insert blocks 54 are fixedly connected to the bottom of the insert ring 53 in an annular array. The outer wall of the insert blocks 54 is movably connected to the inner wall of a rectangular groove 3043. A circular movable hole four extending through to the bottom of the fixing disk 52 is opened at the top of the sealing cover 51. A rotating shaft two 55 is movably connected to the inner wall of the circular movable hole four. A stirring rod 56 is fixedly connected to the bottom of the rotating shaft two 55. A drive motor 57 is fixedly connected to the top of the rotating shaft 55, and a motor housing 58 is fixedly connected to the top of the sealing cover 51. The bottom of the drive motor 57 is fixedly connected to the inner wall of the motor housing 58. When the fixing ring 3041 drives the modular mixing structure 5 to descend, it will lock the sealing cover 51. By starting the drive motor 57, the rotating shaft 55 drives the stirring rod 56 to rotate, mixing the material inside the hopper 2. When the fixing ring 3041 drives the modular mixing structure 5 to rise, it simultaneously contacts the limiting effect of the modular mixing structure 5, which can then lift the modular mixing structure 5, causing the insert block 54 to disengage from the inner wall of the rectangular groove 3043 and the fixing plate 52 to disengage from the inner wall of the fixing ring 3041. This facilitates the disassembly and maintenance of the modular mixing structure 5 and the cleaning of the stirring rod 56.

[0036] Working principle of this invention:

[0037] By activating the stepper motor 34, the rotating shaft 33 drives the threaded rod 35 to rotate. The rotation of the threaded rod 35 causes the connecting shaft 306 to rotate, which in turn drives the conical tooth 307 to rotate. Since the conical tooth 307 meshes with the outer wall of the second conical tooth 411, it drives the connecting rod 412 to rotate on the inner wall of the fixed sleeve 413, which in turn causes the third conical tooth 414 to rotate. The rotation of the third conical tooth 414 drives the fourth conical tooth 415 to rotate, causing the second connecting rod 416 to rotate on the inner wall of the second fixed sleeve 4100 and driving the fifth conical tooth 417 to rotate. The rotation of the fifth conical tooth 417 drives the sixth conical tooth 418 to rotate, causing the third connecting rod 419 to rotate on the inner wall of the third fixed sleeve 410 and driving the seventh conical tooth 4101 to rotate. The rotation of the seventh conical tooth 4101 drives the eighth conical tooth 410... 2. Rotation causes the connecting rod 4103 to rotate on the inner wall of the fixed sleeve 4104, thereby causing the gear 4105 to rotate. The outer wall of the gear 4105 meshes with the outer wall of the connecting plate 4206, thus driving the connecting plate 4206 to move. When the connecting plate 4206 is driven to move to both ends by the gear 4105, the teeth of the gear 4105 will contact the outer wall of the tooth block 4215, driving the tooth block 4215 to move. This causes the double-hole sliding plate 4214 to slide on the outer wall of the fixed rod 4212, compressing the spring 4213. When the teeth of the gear 4105 pass the outer wall of the tooth block 4215, the spring... The second rack 4213 pushes the double-hole sliding plate 4214, causing the toothed block 4215 to return to the tooth groove of the first gear 4105, thus achieving the gear limiting effect. The movement of the second rack 4210 causes the second connecting plate 4206 to move the first rack 4205. The movement of the second connecting plate 4206 then causes the third connecting plate 4207 to move the convex block 4209 against the inner wall of the dovetail groove 4208, improving the stability of the second connecting plate 4206 during movement. The outer wall of the first rack 4205 meshes with the outer wall of the second gear 4204. When the first rack 4205 moves, it drives the second gear 4204 to rotate, and the rotation of the second gear 4204... The moving connecting shaft 4202 rotates on the inner wall of the support sleeve 4203, which in turn causes the worm gear 420 to rotate. The outer wall of the worm gear 420 meshes with the outer wall of the half gear 424, driving the half gear 424 to rotate. This rotation of the half gear 424 causes the limiting rod 423 to rotate on the inner wall of the perforated support arc-shaped plate 422, improving the stability of the half gear 424 during movement. The rotation of the half gear 424 also causes the movable plate 425 to flip, thereby causing the trapezoidal locking block 427 to flip and release the limiting effect on the modular hybrid structure 5. Simultaneously, the rotation of the threaded rod 35 causes the slider 37 to move on the outer wall of the threaded rod 35.The movement of slider 37 causes the front limiting block 30 to slide on the inner wall of the rectangular guide hole 36, thereby moving the front connecting plate 301. The movement of the front connecting plate 301 moves the front fixing plate 302, causing the front arc plate 303 to move the hopper cover 304. The movement of the hopper cover 304 moves the rear fixing plate 302, connecting plate 301, and limiting block 30, causing the sliding sleeve 39 to slide on the outer wall of the sliding rod 38, improving the stability of the hopper cover 304 during movement. The movement of the hopper cover 304 causes the modular hybrid structure 5 to lift or lower. When the modular hybrid structure 5 is lifted, it simultaneously contacts the limiting effect, opening the feed inlet at the top of the hopper 2 for easy loading. When the material descends, the reverse rotation of the conical tooth 307 further drives the half gear 424 to rotate, causing the movable plate 425 and the trapezoidal block 427 to be in a horizontal state. When the fixed ring 3041 in the hopper cover 304 drives the modular hybrid structure 5 to descend and contact the inclined surface of the trapezoidal block 427, it will push the trapezoidal block 427, causing the rectangular guide rod 426 to slide on the inner wall of the rectangular through hole. At the same time, it will push the circular guide rod 428 to slide on the inner wall of the circular movable hole and compress the spring 429. When the fixed ring 3041 moves the modular hybrid structure 5 to below the trapezoidal block 427 and stops at the top of the limiting sealing ring 305, the spring 429 will push the trapezoidal block 427 to lock at the top of the modular hybrid structure 5 for a limiting effect.

[0038] When the fixed ring 3041 lowers the modular mixing structure 5, it locks the sealing cover 51. The drive motor 57 is started, causing the rotating shaft 55 to rotate and the stirring rod 56 to mix the material inside the hopper 2. When the fixed ring 3041 raises the modular mixing structure 5, it also contacts the limiting effect, which allows the modular mixing structure 5 to be raised. This causes the insert block 54 to disengage from the inner wall of the rectangular groove 3043, and the fixed plate 52 to disengage from the inner wall of the fixed ring 3041, making it easier to disassemble the modular mixing structure 5 for maintenance and to clean the stirring rod 56.
