Description

Technical Field

[0001] The present invention relates to the technical field of putty powder screening, and particularly relates to a putty powder screening device with a maze structure. Background Art

[0002] Putty powder screening devices are mainly used in the construction industry to perform particle size grading and impurity removal on dry powder materials such as putty powder to ensure the quality and performance of putty powder.

[0003] In the existing putty powder screening device, after pouring putty powder into the screening cylinder through the feed hopper, the putty powder is screened in the screening cylinder. However, since the inner cavity of the feed hopper directly leads to the bottom and has no complex structure, it is impossible to control the feeding amount of putty powder. At the same time, the putty powder passes straight through the feed hopper, which easily causes dust to rise and spread, polluting the air.

[0004] In view of the above problems, a putty powder screening device with a maze structure that can control the feeding amount of putty powder and effectively prevent the putty powder from rising and spreading has now been developed. Summary of the Invention

[0005] In order to overcome the disadvantages that the inner cavity of the feed hopper directly leads to the bottom, has no complex structure, cannot control the feeding amount of putty powder, and the putty powder passes straight through the feed hopper, which easily causes dust to rise and spread and pollute the air, the present invention provides a putty powder screening device with a maze structure that can control the feeding amount of putty powder and effectively prevent the putty powder from rising and spreading.

[0006] The technical solution of the present invention is: a putty powder screening device with a maze structure, including support feet, a screening bin, a maze structure feed hopper, a telescopic plate, a synchronous frame, an adjusting screw, a screening cylinder, and a power mechanism. The upper side of the support feet is connected with a screening bin, the upper side of the left part of the screening bin is connected with a maze structure feed hopper, a plurality of telescopic plates are slidably connected inside the maze structure feed hopper, a synchronous frame is slidably connected between the telescopic plates, the synchronous frame is slidably connected with the maze structure feed hopper, the rear side of the maze structure feed hopper is rotatably connected with an adjusting screw, the adjusting screw is threadedly connected with the synchronous frame, the screening cylinder is rotatably connected inside the screening bin, the maze structure feed hopper is rotatably connected with the screening cylinder, and a power mechanism capable of accelerating the screening speed of putty powder is arranged between the screening bin and the screening cylinder. Rotate the adjusting screw to move the synchronous frame, drive the telescopic plates to move synchronously, and adjust the distance between the telescopic plates so that the putty powder enters the screening cylinder through the gap between the telescopic plates.

[0007] As a preferred technical solution of the present invention, flanges are provided on both the lower side and the right side of the screening bin.

[0008] As a preferred technical solution of the present invention, the lower part of the maze structure feed hopper is of an inclined structure.

[0009] As a preferred technical solution of the present invention, the power mechanism includes a double-shaft motor, a first gear, and a second gear. The double-shaft motor is connected to the upper left part of the screening bin. The first gear is connected to the left output shaft of the double-shaft motor. The second gear is connected to the left part of the screening cylinder. The second gear meshes with the first gear. When the double-shaft motor is started, it drives the first gear to rotate and mesh with the second gear, causing the screening cylinder to rotate within the screening bin, thereby accelerating the screening speed of putty powder.

[0010] As a preferred technical solution of the present invention, it further includes a knocking-off mechanism. The knocking-off mechanism includes a connecting shaft, a first support frame, a lifting frame, and a first spring. The connecting shaft is connected to the right output shaft of the double-shaft motor. The first support frame is connected to the upper side of the middle part of the screening bin. The connecting shaft is rotatably connected to the first support frame. The lifting frame is slidably connected to the first support frame. The lifting frame passes through the screening bin. The connecting shaft and the lifting frame are in pressing fit. A first spring is connected between the lifting frame and the first support frame. When the double-shaft motor is started, it drives the connecting shaft to rotate, causing the connecting shaft to press the lifting frame. Through the action of the first spring, the lifting frame moves up and down in the first support frame, causing the lifting frame to knock on the screening cylinder.

[0011] As a preferred technical solution of the present invention, it further includes a dispersing mechanism. The dispersing mechanism includes a guiding ring, a support arm, a connecting arm, and a dispersing disc. The guiding ring is connected to the inner side of the left part of the screening cylinder. The support arm is connected to the right part inside the maze-structured feed hopper. The connecting arm is slidably connected to the support arm. The connecting arm is in contact and fit with the guiding ring. The lower part of the connecting arm is connected to the dispersing disc. When the screening cylinder rotates, it drives the guiding ring to rotate, causing the connecting arm to move along the guiding ring, so that the connecting arm moves left and right on the support arm, and further drives the dispersing disc to move left and right.

[0012] As a preferred technical solution of the present invention, a plurality of dispersing grooves are formed on the dispersing disc.

[0013] As a preferred technical solution of the present invention, it further includes a stopping mechanism. The stopping mechanism includes a guide sleeve, a spatial cam, a first sliding frame, a second sliding frame, a second spring, a second support frame, a rotating plate and a torsion spring. The upper side of the right part of the screening bin is connected with a guide sleeve, and the right side of the connecting shaft is connected with a spatial cam. The guide sleeve is slidably connected with a first sliding frame, and the first sliding frame is in contact and cooperation with the spatial cam.

A second spring is connected between the first sliding frame and the second sliding frame. The inner side of the right part of the screening bin is connected with a second support frame, and a rotating plate is rotatably connected to the second support frame. The rotating plate is in extrusion cooperation with the second sliding frame. Torsion springs are connected between the front and rear parts of the rotating plate and the second support frame respectively. When the first sliding frame moves to the right, the second spring is compressed and contracted, thereby pushing the second sliding frame to move to the right, so that the second sliding frame pushes the rotating plate to rotate and no longer closes the right end of the screening cylinder, and the torsion spring deforms. When the first sliding frame resets, through the springback of the second spring, the second sliding frame resets, and then through the restoration of the torsion spring, the rotating plate resets to close the right end of the screening cylinder, realizing the intermittent opening and closing of the screening cylinder.

[0014] As a preferred technical solution of the present invention, it further includes an intermittent mechanism. The intermittent mechanism includes a crankshaft, a connecting frame and a lifting plate. The left output shaft of the double-shaft motor is connected with a crankshaft on the left side, and a lifting plate is slidably connected to the upper right part of the labyrinth structure feeding hopper. A connecting frame is connected to the upper side of the lifting plate, and the connecting frame is movably connected with the crankshaft. When the double-shaft motor starts, it drives the crankshaft to rotate, so that the connecting frame moves, driving the lifting plate to move up and down in the labyrinth structure feeding hopper.

[0015] As a preferred technical solution of the present invention, it further includes a closing mechanism. The closing mechanism includes a connecting block, a rotating cover and a sealing ring. Two connecting blocks are connected to the upper right side of the labyrinth structure feeding hopper, and a rotating cover is rotatably connected between the connecting blocks. A sealing ring is connected to the left side of the rotating cover. After the labyrinth structure feeding hopper stops feeding, the rotating cover is rotated to make the rotating cover close to the labyrinth structure feeding hopper, and the labyrinth structure feeding hopper is sealed through the sealing ring.

[0016] Beneficial effects: 1. By rotating the adjusting screw rod in the present invention, the synchronous frame moves, driving the telescopic plate to move synchronously, adjusting the distance between the telescopic plates, so that the putty powder enters the screening cylinder from the gap between the telescopic plates, achieving the effect of being able to control the feeding amount of the putty powder and effectively preventing the putty powder from flying up and spreading.

[0017] 2. When the double-shaft motor starts in the present invention, it drives the connecting shaft to rotate, so that the connecting shaft squeezes the lifting frame. Through the acting force of the first spring, the lifting frame moves up and down in the first support frame, so that the lifting frame knocks on the screening cylinder, achieving the effect of being able to shake off the putty powder attached to the screening cylinder and reducing the loss of putty powder.

[0018] 3. While the screening cylinder rotates, the guiding ring is driven to rotate, causing the connecting arm to move along the guiding ring, enabling the connecting arm to move left and right on the supporting arm, and then driving the dispersing plate to move left and right, which can disperse the putty powder and ensure the screening effect of the putty powder.

[0019] 4. After the first sliding frame resets, the second sliding frame is reset by the rebound of the second spring, and then the rotating plate is reset by the restoration of the torsion spring to close the right end of the screening cylinder, realizing the intermittent opening and closing of the screening cylinder, achieving the effect of being able to extend the residence time of the putty powder in the screening cylinder and ensuring the complete screening of the putty powder.

[0020] 5. While the dual-axis motor starts, the crankshaft is driven to rotate, causing the connecting frame to move and driving the lifting plate to move up and down in the labyrinth structure feed hopper, achieving the effect of being able to feed the putty powder intermittently and avoiding the accumulation of the putty powder.

[0021] 6. After the labyrinth structure feed hopper stops feeding, the rotating cover is rotated to make the rotating cover close to the labyrinth structure feed hopper, and the labyrinth structure feed hopper is sealed through the sealing ring, achieving the effect of being able to close the labyrinth structure feed hopper and ensuring that the dust cannot spread into the air.

Detailed implementation manners

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited.

[0034] A putty powder screening device with a labyrinth structure, as Figures 1 - 3 shown, includes support feet 1, screening bin 2, labyrinth structure feed hopper 3, telescopic plate 31, synchronization frame 32, adjusting screw 33, screening cylinder 4 and power mechanism 5. The upper side of the support feet 1 is connected with the screening bin 2. Flanges are provided on the lower side and the right side of the screening bin 2 to facilitate the connection of the putty powder collection device. The upper side of the left part of the screening bin 2 is connected with the labyrinth structure feed hopper 3. The lower part of the labyrinth structure feed hopper 3 is of an inclined structure to facilitate the feeding of putty powder. Five telescopic plates 31 are slidably connected inside the labyrinth structure feed hopper 3. A synchronization frame 32 is slidably connected between the telescopic plates 31. The synchronization frame 32 is slidably connected with the labyrinth structure feed hopper 3. The adjusting screw 33 is rotatably connected to the rear side of the labyrinth structure feed hopper 3. The adjusting screw 33 is threadedly connected with the synchronization frame 32. The screening cylinder 4 is rotatably connected inside the screening bin 2. The labyrinth structure feed hopper 3 is rotatably connected with the screening cylinder 4. A power mechanism 5 is provided between the screening bin 2 and the screening cylinder 4.

[0035] As Figure 1 and Figure 4 shown, the power mechanism 5 includes a dual-shaft motor 51, a first gear 52 and a second gear 53. The dual-shaft motor 51 is connected to the upper left part of the screening bin 2. The first gear 52 is connected to the left output shaft of the dual-shaft motor 51. The second gear 53 is connected to the left part of the screening cylinder 4. The second gear 53 meshes with the first gear 52.

[0036] When using the present invention, first place the supporting feet 1 in the putty powder screening area to support the screening bin 2 with the supporting feet 1. Then pour the putty powder to be screened into the maze-structured feed hopper 3, so that the putty powder enters the screening cylinder 4 from the maze-structured feed hopper 3 for screening. The putty powder with a smaller particle size falls below the screening bin 2 through the screening cylinder 4, and the putty powder with a larger particle size flows out from the right end of the screening bin 2. When pouring the putty powder into the maze-structured feed hopper 3, the adjusting screw 33 can be rotated to move the synchronous frame 32, driving the telescopic plate 31 to move synchronously, and adjusting the distance between the telescopic plates 31, so that the putty powder enters the screening cylinder 4 from the gap between the telescopic plates 31, thus playing a role in controlling the feeding amount of the putty powder and effectively preventing the putty powder from rising and spreading. When the putty powder is screened in the screening cylinder 4, the double-shaft motor 51 can be started to drive the first gear 52 to rotate and engage with the second gear 53, so that the screening cylinder 4 rotates in the screening bin 2, thereby accelerating the screening speed of the putty powder.

[0037] As Figure 1 and Figure 5 shown, it further includes a knocking-off mechanism 6. The knocking-off mechanism 6 includes a connecting shaft 61, a first support frame 62, a lifting frame 63 and a first spring 64. The connecting shaft 61 is connected to the right output shaft of the double-shaft motor 51, and the first support frame 62 is connected to the upper side of the middle part of the screening bin 2. The connecting shaft 61 is rotatably connected to the first support frame 62. The lifting frame 63 is slidably connected to the first support frame 62. The lifting frame 63 passes through the screening bin 2. The connecting shaft 61 is in extrusion fit with the lifting frame 63. A first spring 64 is connected between the lifting frame 63 and the first support frame 62.

[0038] By using the knocking-off mechanism 6 of this device, the putty powder on the screening cylinder 4 can be knocked off. When the double-shaft motor 51 is started, it drives the connecting shaft 61 to rotate, so that the connecting shaft 61 squeezes the lifting frame 63. Through the acting force of the first spring 64, the lifting frame 63 moves up and down in the first support frame 62, so that the lifting frame 63 knocks on the screening cylinder 4, thus playing a role in knocking off the putty powder attached to the screening cylinder 4 and reducing the loss of putty powder.

[0039] As Figure 1 、 Figure 6 and Figure 7 shown, it further includes a dispersing mechanism 7. The dispersing mechanism 7 includes a guide ring 71, a support arm 72, a connecting arm 73 and a dispersing disk 74. The guide ring 71 is connected to the inner side of the left part of the screening cylinder 4, the support arm 72 is connected to the right part inside the maze-structured feed hopper 3, the connecting arm 73 is slidably connected to the support arm 72, the connecting arm 73 is in contact fit with the guide ring 71, and the lower part of the connecting arm 73 is connected to the dispersing disk 74. A plurality of dispersing grooves are formed on the dispersing disk 74, which is convenient for dispersing the putty powder.

[0040] Using the dispersion mechanism 7 of this device, putty powder can be dispersed. While the screening cylinder 4 rotates, it drives the guide ring 71 to rotate, causing the connecting arm 73 to move along the guide ring 71, enabling the connecting arm 73 to move left and right on the support arm 72, and then driving the dispersion disc 74 to move left and right, thereby playing a role in dispersing the putty powder and ensuring the screening effect of the putty powder.

[0041] As Figure 1 and Figure 8 shown, it further includes a staying mechanism 8. The staying mechanism 8 includes a guide sleeve 81, a spatial cam 82, a first sliding frame 83, a second sliding frame 84, a second spring 85, a second support frame 86, a rotating plate 87, and a torsion spring 88. A guide sleeve 81 is connected to the upper side of the right part of the screening bin 2, and a spatial cam 82 is connected to the right side of the connecting shaft 61. The first sliding frame 83 is slidably connected to the guide sleeve 81, and the first sliding frame 83 is in contact and cooperation with the spatial cam 82. The second sliding frame 84 is slidably connected to the upper right part of the screening bin 2, and the second sliding frame 84 is slidably connected to the first sliding frame 83. A second spring 85 is connected between the first sliding frame 83 and the second sliding frame 84. A second support frame 86 is connected to the inner side of the right part of the screening bin 2, and a rotating plate 87 is rotatably connected to the second support frame 86. The rotating plate 87 is in extrusion cooperation with the second sliding frame 84, and torsion springs 88 are connected between the front and rear parts of the rotating plate 87 and the second support frame 86 respectively.

[0042] Using the staying mechanism 8 of this device, the screening time of the putty powder can be extended. While the connecting shaft 61 rotates, it drives the spatial cam 82 to rotate. Through the contact and cooperation between the spatial cam 82 and the first sliding frame 83, the first sliding frame 83 moves left and right on the guide sleeve 81. When the first sliding frame 83 moves to the right, the second spring 85 is compressed and contracted, and then it pushes the second sliding frame 84 to move to the right, causing the second sliding frame 84 to push the rotating plate 87 to rotate and no longer close the right end of the screening cylinder 4, and the torsion spring 88 deforms. When the first sliding frame 83 resets, through the rebound of the second spring 85, the second sliding frame 84 resets, and then through the restoration of the torsion spring 88, the rotating plate 87 resets to close the right end of the screening cylinder 4, realizing the intermittent opening and closing of the screening cylinder 4, thereby playing a role in being able to extend the staying time of the putty powder in the screening cylinder 4 and ensuring the complete screening of the putty powder.

[0043] As Figure 1 and Figure 9 shown, it further includes an intermittent mechanism 9. The intermittent mechanism 9 includes a crankshaft 91, a connecting frame 92, and a lifting plate 93. The left output shaft of the double-shaft motor 51 is connected to the left side of the crankshaft 91. The lifting plate 93 is slidably connected to the upper right part of the labyrinth structure feeding hopper 3. The connecting frame 92 is connected to the upper side of the lifting plate 93, and the connecting frame 92 is movably connected to the crankshaft 91.

[0044] Using the intermittent mechanism 9 of the present device, the putty powder can be fed intermittently. When the double-shaft motor 51 starts, it drives the crankshaft 91 to rotate, causing the connecting frame 92 to move, and driving the lifting plate 93 to move up and down in the labyrinth structure feed hopper 3, thus enabling the putty powder to be fed intermittently and avoiding the accumulation of putty powder.

[0045] As Figure 1 and Figure 10 shown, it further includes a closing mechanism 10. The closing mechanism 10 includes a connecting block 101, a rotating cover 102 and a sealing ring 103. There are two front and rear connecting blocks 101 connected to the upper right side of the labyrinth structure feed hopper 3. The rotating cover 102 is rotatably connected between the connecting blocks 101, and the sealing ring 103 is connected to the left side of the rotating cover 102.

[0046] Using the closing mechanism 10 of the present device, the labyrinth structure feed hopper 3 can be closed. After the labyrinth structure feed hopper 3 stops feeding, rotate the rotating cover 102 to make the rotating cover 102 close to the labyrinth structure feed hopper 3, and seal the labyrinth structure feed hopper 3 through the sealing ring 103, thus playing a role in closing the labyrinth structure feed hopper 3 and ensuring that dust cannot spread into the air.

[0047] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
