Description

Technical Field

[0001] This invention relates to the field of single-column mixer technology, specifically a sealed, dust-free single-column mixer. Background Technology

[0002] The sealed dust-free single-column mixer can achieve uniform mixing of powder, granules or paste materials, and can effectively avoid material dust, pollution or interference from the external environment during the mixing process.

[0003] The existing equipment has a fixed angle between the upper clamping frame and the single-column rotating mechanism, and it is always directly above the lower clamping frame. In actual use, for hoppers with a relatively high height, the fixed upper clamping frame will seriously obstruct the placement space of the hopper, which not only increases the difficulty of aligning the hopper with the lower clamping frame, but also easily leads to the hopper scraping or colliding with the upper clamping frame.

Furthermore, through the coordinated cooperation of the flipping component and the adjusting component, the lower clamping plate can be simultaneously driven to move towards the center of the lower crossbeam during the process of the upper crossbeam resetting from a vertical state to a horizontal state.

[0029] Please see Figures 1-11 In this embodiment of the invention, a sealed dust-free single-column mixer includes a base 1 and an upper clamping frame and a lower clamping frame disposed on one side of the base 1. The base 1 serves as the overall support foundation for the equipment, and its central area is provided with a cavity for installing transmission components. A single-column rotary mechanism is disposed at the center of one side of the base 1. The lower clamping frame is disposed at the lower end of the rotary mechanism, and the upper clamping frame is disposed at the upper end of the rotary mechanism, and is arranged vertically corresponding to the lower clamping frame.

[0030] It should be noted that: the rotary mechanism is connected to the transmission component in the accommodating cavity of the base 1; the upper clamping frame and the lower clamping frame can rotate synchronously with the single-column rotary mechanism; and a hydraulic rod 5 is fixedly installed between the upper clamping frame and the lower clamping frame, which can cause the upper clamping frame to rise and fall in the vertical direction of the rotary mechanism; and a vacuum adsorption component 4 is provided on the upper end face of the lower clamping frame. The sealing interface of this component is adapted to the bottom of the mixing hopper to be loaded, so that the equipment itself does not come into contact with the material, resulting in zero contamination of the material in the hopper; and through the cooperation of the vacuum adsorption component 4 and the discharge valve of the hopper, an adsorption force is applied from the vertical direction to firmly hold the bottom of the hopper. The material is firmly adsorbed onto the lower clamping frame to prevent slight movement or displacement of the hopper. Simultaneously, it avoids potential material leakage during mixing due to centrifugal force or material impact causing minor gaps in the discharge valve at the bottom of the hopper. In use, after the mixing hopper is placed on the upper part of the lower clamping frame, the upper clamping frame descends via hydraulic rod 5, cooperating with the lower clamping frame to clamp the hopper and form a sealed cavity. The vacuum adsorption component 4 is activated, creating a dust-free negative pressure environment within the sealed cavity. Simultaneously, the single-column rotary mechanism, driven by the drive unit, synchronously rotates the upper clamping frame, the lower clamping frame, and the sealed hopper, achieving a sealed and dust-free mixing operation for the material within the hopper.

[0031] Furthermore, the upper clamping frame includes an upper horizontal frame 2 and a support arm 21. A flipping component is provided at the connection between the upper horizontal frame 2 and the support arm 21. The flipping component is configured to drive the upper horizontal frame 2 to switch between horizontal and vertical states relative to the support arm 21. The lower clamping frame includes a lower horizontal frame 3 and an extension arm 32. One end of the extension arm 32 is fixedly connected to one side of the lower horizontal frame 3. A lower clamping plate 31 is elastically slidably provided at the top end of the extension arm 32. An adjustment component 6 is provided between the upper horizontal frame 2 and the lower horizontal frame 3. The adjustment component 6 can drive the lower clamping plate 31 to move towards the lower horizontal frame 3. The extension arm 32 is symmetrically arranged along the center of the lower horizontal frame 3, and four sets are symmetrically arranged on both sides of the lower horizontal frame 3. Similarly, four sets of lower clamping plates 31 are also provided.

[0032] This invention, through the coordinated operation of the flipping component and the adjusting component 6, solves the problem of obstruction during hopper placement, facilitating hopper placement. When hopper placement is required, the flipping component is activated, causing the upper crossbeam 2 to flip upward relative to the support arm 21, thus removing obstruction above the hopper. At this time, the lower clamping plate 31 is positioned on the extension arm 32 away from the lower crossbeam 3, making hopper placement easier and preventing collisions between the hopper and the upper or lower clamping frames. After placement, the flipping component resets and then moves downward under the action of the hydraulic rod 5 to cooperate with the lower clamping frame in clamping the hopper. During the clamping frame flipping and resetting process, the flipping component, in conjunction with the adjusting component 6, drives the lower clamping plate 31 to move downwards to the horizontal frame 3, thereby clamping the outer wall of the bottom of the hopper. In this process, it also promotes the center alignment of the hopper downwards to the horizontal frame 3, avoiding the possibility that the hopper may be misplaced, which could prevent the vacuum adsorption component 4 from effectively performing vacuum sealing. In short, when the flipping component drives the upper horizontal frame 2 to flip to the vertical position, the flipping component causes the adjusting component 6 to complete self-locking. When the flipping component drives the upper horizontal frame 2 to flip to the horizontal position, the flipping component drives the adjusting component 6 to perform linear motion and causes the lower clamping plate 31 to move downwards to the horizontal frame 3.

[0033] In summary, through the coordinated operation of the flipping component and the adjusting component 6, the present invention can simultaneously drive the lower clamping plate 31 to move towards the center of the lower crossbeam 3 during the process of the upper crossbeam 2 resetting from a vertical state to a horizontal state. On the one hand, the multiple sets of symmetrically arranged lower clamping plates 31 can automatically correct the placement deviation of the hopper, ensuring that the bottom opening of the hopper is precisely aligned with the vacuum adsorption component 4. On the other hand, it achieves axial clamping of the top of the hopper by the upper clamping frame and radial clamping of the bottom outer wall of the hopper by the lower clamping plate 31. The double clamping structure greatly improves the installation stability of the hopper, effectively ensures the sealing effect of the vacuum adsorption component 4, and avoids negative pressure leakage and dust overflow.

[0034] Please see Figures 1-4The flipping assembly includes a sleeve shaft 72; the sleeve shaft 72 is disposed inside the top of the support arm 21, a worm gear 7 is fixedly disposed around the sleeve shaft 72, a worm 73 is drivenly connected below the worm gear 7, a motor is drivenly disposed at the end of the worm 73, the motor is disposed on the outer side wall of the support arm 21, and a fixed shaft 71 is disposed at the center of the end of the upper cross frame 2, which is slidably adapted to the sleeve shaft 72. The motor is started to drive the worm 73 to rotate, the worm 73 rotates to drive the fixed shaft 71 to rotate, and the sleeve shaft 72 rotates to drive the upper cross frame 2 to flip upward relative to each other through the fixed shaft 71. At this time, the space above the hopper to be placed is no longer obstructed, thus facilitating the placement of hoppers with greater height. After the hopper is placed on the lower clamping frame, the motor is started to drive the worm 73 to reset, and then the upper cross frame 2 is flipped and reset through the sleeve shaft 72 and the fixed shaft 71, thus avoiding the problem that the space above the hopper with greater height may be obstructed when it is placed, causing the hopper to collide with the upper and lower clamping frames.

[0035] Please see Figure 5 Each of the multiple sets of lower clamping plates 31 has an approximately L-shaped plate on its top, and the L-plates on the multiple sets of lower clamping plates 31 are mirror images of each other, that is, each set of L-plates corresponds to a corner of the square structure, thereby achieving clamping and alignment of the hopper. However, in actual use, the placement of the hopper requires precise operation by the personnel, otherwise the hopper is prone to collision with the L-plate. Therefore, the bottom of the lower clamping plate 31 is elastically provided with a slide 34. The slide 34 is slidably connected to one end of the top of the extension arm 32, and the slide 34 is located at the end of the extension arm 32 away from the lower crossbar 3. The slide 34 and the inner wall of the extension arm 32 are elastically connected by a spring. With the lower clamping plate 31 that can slide on the extension arm 32, the lower clamping plate 31 is located at the end of the extension arm 32 away from the lower crossbar 3 in the initial placement of the hopper, thereby increasing the distance between the multiple sets of lower clamping plates 31, and thus facilitating the placement of the hopper by the personnel.

[0036] Furthermore, a pull plate 8 is slidably disposed within the lower crossbar 3, and a fixing plate 33 is fixedly disposed on the side of the slide block 34 near the pull plate 8. The fixing plate 33 is located above the pull plate 8, and a guide post is fixedly disposed at one end of the fixing plate 33 near the pull plate 8. A guide groove 81 is provided on the pull plate 8 to slide and adapt to the guide post. Preferably, the pull plate 8 is arranged in a "U" shape, and the number and position of the guide grooves 81 correspond to the lower clamping plate 31. The guide grooves 81 are disposed on the extension plate of the pull plate 8 and are mirror-image disposed along the center of the pull plate 8. Thus, during use, when flipping... When the rotating component causes the upper horizontal frame 2 to switch from a vertical state to a horizontal state, the flipping component drives the adjusting component 6 to move the pull plate 8 away from the base 1. The moving pull plate 8, through the cooperation of the guide groove 81 and the guide column, causes the fixed plate 33 to move towards the lower horizontal frame 3, thereby causing the slide 34 and the lower clamping plate 31 to move downward, thus achieving the clamping work on the side wall of the hopper. At the same time, if there is a deviation in the placement of the hopper, it can also be corrected under the action of multiple sets of synchronously moving lower clamping plates 31, so that the bottom opening of the hopper corresponds and matches the vacuum adsorption component 4.

[0037] Please see Figures 2-8 The adjusting component 6 includes a sleeve 61 and an inner rod 62. The sleeve 61 is slidably sleeved on the periphery of the inner rod 62. The sleeve 61 and the inner rod 62 can slide relative to each other. A buckle is fixedly provided at the relatively far ends of the sleeve 61 and the inner rod 62. The buckle is elastically slidably connected to the inner walls of the corresponding upper clamping frame and lower clamping frame. The sliding direction is the direction in which the sleeve 61 and the inner rod 62 slide relative to each other. The sleeve 61 and the inner rod 62 are symmetrically arranged along the center of the pull plate 8. A pushing block 611 is fixedly provided at the bottom of the sleeve 61 and slides with the pull plate 8. The pushing block 611 is provided with an inclined surface facing the base 1.

[0038] Furthermore, an installation plate 65 is slidably embedded in the side of the inner rod 62 away from the base 1. Limiting posts 66 are arrayed along the length direction of the inner rod 62 on the side of the installation plate 65 away from the base 1. A through hole 613 is provided on the side wall of the sleeve 61, which is slidably adapted to the limiting post 66. When the limiting post 66 is not adapted to the through hole 613, the sleeve 61 and the inner rod 62 can slide relative to each other with the upper clamping frame. A top block 64 is fixedly provided at the top of the installation plate 65. A trigger plate 74 is elastically provided on the outer side wall of the sleeve shaft 72, which is slidably engaged with the top block 64. The trigger plates 74 are symmetrically arranged along the center of the sleeve shaft 72.

[0039] For specific usage, please refer to... Figure 8As shown, in the initial state where the upper crossbeam 2 is in a horizontal position, the trigger plate 74 is located directly below the sleeve shaft 72, the top block 64 corresponds to the top of the inner rod 62, and the limiting post 66 retracts into the side wall of the inner rod 62. During use, when the worm gear 73 rotates, driving the worm wheel 7 to rotate, the sleeve shaft 72 rotates accordingly, thereby driving the trigger plate 74 to rotate. When the upper crossbeam 2 switches from a horizontal to a vertical position, the trigger plate 74 is positioned relative to the top block 64, pushing the top block 64 away from the inner rod 62, thus moving the mounting plate 65 and the limiting post 66. This causes the limiting post 66 to extend into the through hole 613, completing the relative limiting of the sleeve 61 and the inner rod 62. Subsequently, when the upper crossbeam 2 resets, the sleeve shaft 72 rotates, driving the trigger plate 74 to rotate and reset. During this process, the trigger plate 74 will act on the inner rod 62. The top of 2 moves downward, causing the sleeve 61 to move downward, which in turn causes the push block 611 to slide into the pull plate 8. The inclined surface of the push block 611 causes the pull plate 8 to move towards the base 1, and the guide groove 81 and guide column drive the lower clamping plate 31 to move towards the lower crossbar 3, thereby completing the clamping of the hopper. Preferably, in order to ensure that the top block 64 can be reset after the end of the trigger plate 74 is completely separated from the end of the inner rod 62, an elastic limiting member (not shown in the figure) is provided at the top of the inner rod 62. That is, when the top block 64 is pushed, the elastic limiting member of the trigger plate 74 limits the position of the top block 64. When the trigger plate 74 is completely separated from the top of the inner rod 62, the elastic limiting member automatically resets and releases the limiting of the top block 64, and then the top block 64 can be reset.

[0040] To limit the position of the pull plate 8 after being driven by the push block 611, a side plate 63 is elastically provided on the side of the sleeve 61 near the through hole 613. The bottom of the side plate 63 extends into the interior of the push block 611. A square block 615 is elastically provided inside the push block 611. A transmission member 614 is provided between the top of the square block 615 and the adjusting component 6. The transmission member 614 is rotatably connected to the adjusting component 6. Limiting plates 612 are arranged in an array along the height direction at the end of the square block 615 away from the side plate 63. A groove 343 is provided on the side wall of the pull plate 8. A retaining plate 344 that slides with the limiting plate 612 is elastically connected in the groove 343. The transmission member 614 is L-shaped, and a protrusion that slides with the transmission member 614 is provided at the center of the top of the square block 615 near the limiting plate 612. The end of the transmission member 614 away from the limiting plate 612 is connected to the side plate 63. Sliding engagement; when the limiting post 66 is fitted with the through hole 613, the limiting post 66 pushes the side plate 63 to move away from the sleeve 61. The movement of the side plate 63 pushes one end of the transmission component 614 to move, thereby causing the transmission component 614 to rotate. Subsequently, the protrusion drives the square block 615 to move into the pushing block 611, thereby causing the limiting plate 612 to retract into the pushing block 611. At this time, the downward movement of the pushing block 611 will not be hindered by the conflict between the limiting plate 612 and the pull plate 8. When the limiting post 66 separates from the through hole 613, the side plate 63 elastically resets. At this time, the transmission component 614 is no longer restricted, and the square block 615 elastically resets, allowing the limiting plate 612 to move and extend into the clamping plate 344 to limit the position of the pull plate 8 and the pushing block 611. This achieves the limitation of the pull plate 8 after movement, ensuring the stability of the hopper during the mixing process. The specific movements of the square block 615, the transmission component 614, and the side plate 63 can be referred to Figure 10 As shown.

[0041] Please see Figure 5 , Figure 11A sliding rod 341 is fixedly installed at the bottom of the lower clamping plate 31. The sliding rod 341 and the sliding seat 34 are elastically connected by a spring. A pulley is installed at the bottom of the sliding seat 34. A pull rope 342 is fixedly installed between the bottom of the sliding rod 341 and the end of the clamping plate 344 near the base 1. The end of the pull rope 342 away from the clamping plate 344 slides through the pulley and is fixed to the bottom of the sliding rod 341. In the initial state, there is a gap between the lower clamping plate 31 and the top of the extension arm 32 under the elastic action of the sliding rod 341. At this time, the clamping plate 344 is in the groove 343 in a position away from the limiting plate 612. When the hopper is placed on the lower clamping plate 31, the lower clamping plate 31 is pressed down, causing the sliding rod 341 to move down. The pulley pulls the rope 342, causing the clamping plate 344 to move a certain distance into the groove 343, thus aligning the clamping plate 344 with the limiting plate 612. This allows for subsequent adaptation to the limiting plate 612. After mixing is complete, the flipping component causes the upper horizontal frame 2 to switch to a vertical state. Although the adjusting component 6 completes self-locking at this time, when the hopper is removed from the lower clamping frame, the lower clamping plate 31 and the sliding rod 341 elastically reset. The pull rope 342 then causes the clamping plate 344 to reset, separating it from the limiting plate 612. This ensures that even if no material is added, switching the upper horizontal frame 2 to a horizontal state will not result in the limiting plate 612 and the clamping plate 344 being unable to move due to their interaction.
