Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically a valve-type feeder. Background Technology

[0002] In industrial production, it is necessary to add solid particles, powders and other particulate matter into certain equipment to process raw materials, which requires the use of valve feeders.

[0003] Utility model patent CN218950015U discloses a feeding device, including a storage tank with an inlet at the top and an outlet at the bottom. The outlet is connected to the inlet of a Venturi pump, and the outlet of the Venturi pump is connected to a conveying pipe. An anti-clogging device is also installed inside the storage tank. This utility model uses a Venturi pump to deliver additive powder from the storage tank to the conveying pipe, allowing for control of the amount of additive powder added. The additive powder is then conveyed to the bottom of the flakes via the conveying pipe. The flakes act as a barrier, reducing the dispersion of the additive powder and thus reducing additive loss. This design is not only more environmentally friendly but also lowers production costs.

[0004] The device has shortcomings in its use. It cannot feed raw materials at regular intervals, and solid particles tend to clump together in the storage tank, resulting in poor material flow and blockage. To address these issues, the inventors proposed a valve-type feeder. Summary of the Invention

One of the blocking plates is positioned opposite to the bottom of the guide tube. A fan-shaped plate is fixedly mounted on the outer ring of the top of the circular plate. There are several arc-shaped blocks, which are arranged between two sliding grooves. One side of the fan-shaped plate slides in cooperation with the inner wall of the arc-shaped block. A limiting mechanism is provided below the blocking mechanism. The limiting mechanism includes a base plate. A fixed shaft is rotatably arranged at the top center of the base plate. The top end of the fixed shaft is fixedly engaged with the bottom center of the circular plate. A ratchet is fixedly arranged on the surface of the fixed shaft. A pawl is engaged on one side of the ratchet. The pawl is connected to the base plate. Support blocks are symmetrically fixed at both ends of the top of the base plate. A support plate is fixedly arranged on the top of the support blocks. The top of the support plate contacts the outer ring of the bottom of the circular plate.

[0007] Preferably, the lifting mechanism includes a stabilizing plate, one side of which is fixedly engaged with the bottom of the feeding hopper. A vertical plate is fixedly mounted on the top of the stabilizing plate. A mounting groove is provided on one side of the vertical plate.

Two bevel gears are provided on the other end of the horizontal shaft. The bevel gear closer to the horizontal shaft is fitted onto the horizontal shaft, and the bevel gear farther from the horizontal shaft is fitted onto a connecting shaft.

[0009] Preferably, the mounting mechanism includes a long shaft, and mounting plates are symmetrically fixedly disposed at the top and bottom ends of the long shaft, with the end face of the mounting plate fixedly engaged with the inner wall of the feeding hopper.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the feed tube feeds material intermittently, the rotary motor is started to rotate, which drives the rotating shaft and the first gear to rotate, which in turn drives the second gear to rotate. This makes the structure more stable when the first gear rotates, which in turn drives the fixed block and the rotating rod to rotate, which in turn drives the slider to rotate. When the slider rotates, it slides over the circular groove and enters one of the grooves to continue rotating until it leaves the groove. During this process, the circular plate rotates, which in turn drives the baffle plate located at the bottom of the feed tube to move away from the bottom of the feed tube. At this time, the raw material falls from the feed tube into other processing equipment. Then, the other adjacent baffle plate moves to the bottom of the feed tube, and the feed tube completes one intermittent feeding process. This process is repeated to realize the intermittent timed feeding process. 2. When it is necessary to stir the raw materials in the feeding hopper, the drive motor is started to drive the short shaft to rotate, which in turn drives the third gear to rotate, which in turn drives the fourth gear to rotate, which in turn drives the stirring rod and stirring plate to rotate, thus stirring the raw materials in the feeding hopper, preventing the raw materials from clumping, ensuring smooth feeding, and preventing blockage. 3. Through bevel gears, horizontal shaft, square frame, and U-shaped connecting plate, when the second gear rotates, it drives the connecting shaft to rotate, which in turn drives the two bevel gears to rotate, which in turn drives the horizontal shaft and turntable to rotate, which in turn drives the cam to rotate, which in turn drives the two racks to move up and down in the vertical direction, which in turn drives the square frame to slide along the inside of the mounting groove, which drives the U-shaped connecting plate, folded plate, and horizontal plate to move, which in turn drives the drive motor, rotating tube (the rotating tube slides along the long axis), stirring rod, and stirring plate to move in the vertical direction, which facilitates the improvement of the stirring effect of the stirring mechanism, and makes the stirring rod and stirring plate more thoroughly stir the raw materials.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: Figure 1-13As shown, this invention provides a valve-type feeder, including a feeding hopper 1, a guide pipe 2 connected to the bottom of the feeding hopper 1, an installation mechanism 3 inside the feeding hopper 1, a stirring mechanism 4 inside the installation mechanism 3, a lifting mechanism 5 at the top of the feeding hopper 1, a drive mechanism 6 on one side of the lifting mechanism 5, and both the drive mechanism 6 and the lifting mechanism 5 are connected to the stirring mechanism 4. A rotating mechanism 7 is located on one side of the guide pipe 2, a blocking mechanism 8 is located below the rotating mechanism 7, and a limit mechanism 9 is located below the blocking mechanism 8. Solid particles and other raw materials are poured into the feeding hopper 1 for temporary storage, awaiting the feeding process. During feeding, the raw materials leave through the guide pipe 2. A valve for controlling the descent of the raw materials is installed on the guide pipe 2 (not shown in the figure; the valve is prior art). Without further ado, the material is added to the equipment awaiting processing. The installation mechanism 3 facilitates the installation and fixation of the mixing mechanism 4. The mixing mechanism 4 facilitates the mixing of the raw materials inside the feeding hopper 1, preventing the solid particles or powder from clumping inside the feeding hopper 1, ensuring smooth material discharge and preventing blockage. The lifting mechanism 5 facilitates the improvement of the mixing effect of the mixing mechanism 4. The driving mechanism 6 facilitates the rotation of the mixing mechanism 4 to ensure normal operation. The rotating mechanism 7 facilitates the rotation of the blocking mechanism 8, so that the blocking mechanism 8 will no longer block the raw materials from falling from the guide pipe 2 at regular intervals, allowing the raw materials to fall at a time. The limiting mechanism 9 facilitates the limiting of the blocking mechanism 8, so that the blocking mechanism 8 remains stable and does not shake when it is not rotating.

[0029] The rotating mechanism 7 includes a first fixed plate 71, one end of which is fixedly engaged with one side of the guide tube 2. Second fixed plates 72 are symmetrically fixed on both sides of the first fixed plate 71. A U-shaped fixed plate 73 is fixedly fixed at the bottom of the second fixed plate 72. Two third fixed plates 74 are fixedly arranged between the two U-shaped fixed plates 73. A first gear 75 and a second gear 76 are rotatably arranged between the two third fixed plates 74. The first gear 75 meshes with the second gear 76. The first gear 75 is mounted on a rotating shaft 77, and the second gear 76 is mounted on a connecting shaft 78. A rotary motor 79 is installed at the bottom of the first fixed plate 71. The output end of the rotary motor 79 passes through the upper third fixed plate 74 and is fixedly engaged with the top of the rotating shaft 77. A fixed block 710 is fixedly arranged at the bottom of the rotating shaft 77, passing through the lower third fixed plate 74. A rotating rod 711 is fixedly arranged on one side of the fixed block 710. A slider 712 is fixedly arranged at the bottom of the rotating rod 711. A fan-shaped plate 713 is fixedly arranged on the other side of the fixed block 710.

[0030] By adopting the above technical solution, when the shielding mechanism 8 needs to rotate intermittently away from the bottom of the guide tube 2, the rotary motor 79 is started to rotate, which drives the rotating shaft 77 and the first gear 75 to rotate, and then drives the second gear 76 to rotate. This makes the structure more stable when the first gear 75 rotates, which in turn drives the fixed block 710 and the rotating rod 711 to rotate, and then drives the slider 712 to rotate, thus making it easier to drive the shielding mechanism 8 to rotate.

[0031] The shielding mechanism 8 includes a circular plate 81. A circular groove 82 is provided at the center of the top of the circular plate 81. Several sliding grooves 83 are provided on the outer ring of the top of the circular plate 81. The circular groove 82 is connected to the sliding groove 83. The slider 712 is slidably engaged with the sliding groove 83. Several connecting blocks 84 are fixedly provided on the outer wall of the circular plate 81. A shielding plate 85 is fixedly provided at one end of the connecting block 84. One of the shielding plates 85 is positioned opposite to the bottom of the guide tube 2.

[0032] By adopting the above technical solution, when the slider 712 rotates, the slider 712 slides over the circular groove 82 and enters one of the grooves 83 to continue rotating until it leaves the groove 83. During this process, it drives the circular plate 81 to rotate, which in turn drives the baffle plate 85 located at the bottom of the guide pipe 2 to move away from the bottom of the guide pipe 2. At this time, the raw material falls from the guide pipe 2 into other processing equipment. Subsequently, the adjacent baffle plate 85 moves to the bottom of the guide pipe 2, and the guide pipe 2 completes one intermittent feeding process.

[0033] Several arc-shaped blocks 86 are fixedly arranged on the outer ring of the top of the circular plate 81. The arc-shaped blocks 86 are arranged between two sliding grooves 83. One side of the fan-shaped plate 713 slides in cooperation with the inner wall of the arc-shaped blocks 86.

[0034] By adopting the above technical solution, when the arc-shaped block 86 rotates with the fixed block 710, it rotates close to the arc-shaped block 86, making the structure more stable when the slider 712 rotates.

[0035] The limiting mechanism 9 includes a base plate 91, a fixed shaft 92 is rotatably mounted at the top center of the base plate 91, the top of the fixed shaft 92 is fixedly engaged with the bottom center of the circular plate 81, a ratchet 93 is fixedly mounted on the surface of the fixed shaft 92, a pawl 94 is engaged on one side of the ratchet 93, the pawl 94 is connected to the base plate 91, support blocks 95 are symmetrically fixedly mounted at both ends of the top of the base plate 91, a support plate 96 is fixedly mounted on the top of the support blocks 95, and the top of the support plate 96 contacts the bottom outer ring of the circular plate 81.

[0036] By adopting the above technical solution, the cooperation between ratchet 93 and pawl 94 is existing technology and will not be described in detail. When the circular plate 81 rotates, it drives the fixed shaft 92 and ratchet 93 to rotate. When the circular plate 81 stops rotating, the pawl 94 locks the ratchet 93, so that the circular plate 81 and the baffle plate 85 maintain structural stability and will not move.

[0037] The lifting mechanism 5 includes a stabilizing plate 51. One side of the stabilizing plate 51 is fixedly engaged with the bottom of the feeding hopper 1. A vertical plate 52 is fixedly installed on the top of the stabilizing plate 51. An installation groove 53 is opened on one side of the vertical plate 52. A square frame 54 is slidably installed on one side of the installation groove 53. A rack 55 is symmetrically fixed on both sides of the inner wall of the square frame 54. An installation hole is opened on the other side of the vertical plate 52. A horizontal shaft 56 is rotatably installed inside the installation hole. A turntable 57 is fixedly installed at one end of the horizontal shaft 56. One side of the turntable 57 contacts the bottom of the installation groove 53. Multiple protrusions 58 are fixedly installed on the outer ring of the other side of the turntable 57. The protrusions 58 engage with the rack 55. Two bevel gears 59 are installed at the other end of the horizontal shaft 56. The bevel gear 59 closer to the horizontal shaft 56 is fitted onto the horizontal shaft 56, and the bevel gear 59 farther away from the horizontal shaft 56 is fitted onto the connecting shaft 78.

[0038] By adopting the above technical solution, when the second gear 76 rotates, it drives the connecting shaft 78 to rotate, which in turn drives the two bevel gears 59 to rotate, which in turn drives the horizontal shaft 56 and the turntable 57 to rotate, which in turn drives the protrusion 58 to rotate, which in turn drives the two racks 55 to move up and down in the vertical direction, which in turn drives the square frame 54 to slide along the inside of the mounting groove 53.

[0039] A U-shaped connecting plate 510 is fixedly installed on one side of the square frame 54, a folded plate 511 is fixedly installed on one side of the U-shaped connecting plate 510, a horizontal plate 512 is fixedly installed at one end of the folded plate 511, and a round hole 513 is opened at the top of the horizontal plate 512.

[0040] By adopting the above technical solution, when the square frame 54 moves up and down along the vertical direction, it drives the U-shaped connecting plate 510, the folded plate 511 and the horizontal plate 512 to move, thereby driving the stirring mechanism 4 to move up and down along the vertical direction.

[0041] The drive mechanism 6 includes a mounting block 61, one side of which is fixedly engaged with one side of the folded plate 511. A drive motor 62 is fixedly mounted on the bottom of the mounting block 61, and a short shaft 63 is fixedly mounted on the output end of the drive motor 62. A third gear 64 is fitted on the surface of the short shaft 63.

[0042] By adopting the above technical solution, when the stirring mechanism 4 needs to rotate, the drive motor 62 is started to drive the short shaft 63 to rotate, which in turn drives the third gear 64 to rotate, thereby driving the stirring mechanism 4 to rotate.

[0043] The mounting mechanism 3 includes a long shaft 31, and mounting plates 32 are symmetrically fixed at the top and bottom ends of the long shaft 31. The end face of the mounting plate 32 is fixedly engaged with the inner wall of the feeding hopper 1.

[0044] By adopting the above technical solution, the installation plate 32 and the long shaft 31 facilitate the installation and fixation of the stirring mechanism 4.

[0045] The stirring mechanism 4 includes a rotating tube 41, which is slidably engaged with a long shaft 31. A fourth gear 42 is fixedly installed at the top of the rotating tube 41, and a third gear 64 meshes with the fourth gear 42. Multiple stirring rods 43 are fixedly installed at the center of the rotating tube 41, and stirring plates 44 are fixedly installed on the surface of the stirring rods 43. The rotating tube 41 is rotatably engaged with a circular hole 513.

[0046] By adopting the above technical solution, when it is necessary to stir the raw materials, the third gear 64 rotates, which drives the fourth gear 42 to rotate, and then drives the stirring rod 43 and the stirring plate 44 to rotate, so as to stir the raw materials in the feeding hopper 1 and avoid the raw materials from clumping.

[0047] Working principle: When the feed tube 2 feeds material intermittently, the rotary motor 79 is started to rotate, which drives the rotating shaft 77 and the first gear 75 to rotate, and then drives the second gear 76 to rotate. This makes the structure more stable when the first gear 75 rotates, which in turn drives the fixed block 710 and the rotating rod 711 to rotate, and then drives the slider 712 to rotate. When the slider 712 rotates, it slides over the circular groove 82 and enters one of the slide grooves 83 to continue rotating until it leaves the slide groove 83. During this process, the circular plate 81 is driven to rotate, which in turn drives the baffle plate 85 located at the bottom of the feed tube 2 to move away from the bottom of the feed tube 2. At this time, the raw material falls from the feed tube 2 into other processing equipment. Then, the adjacent baffle plate 85 moves to the bottom of the feed tube 2, and the feed tube 2 completes one intermittent feeding process. This process is repeated to realize the intermittent timed feeding process.

[0048] When it is necessary to stir the raw materials in the feeding hopper 1, the drive motor 62 is started to drive the short shaft 63 to rotate, which in turn drives the third gear 64 to rotate, drives the fourth gear 42 to rotate, and then drives the stirring rod 43 and the stirring plate 44 to rotate, so as to stir the raw materials in the feeding hopper 1, avoid the raw materials from clumping, ensure smooth feeding, and prevent blockage.

[0049] When the second gear 76 rotates, it drives the connecting shaft 78 to rotate, which in turn drives the two bevel gears 59 to rotate, which in turn drives the horizontal shaft 56 and the turntable 57 to rotate, which in turn drives the protrusion 58 to rotate, which in turn drives the two racks 55 to move up and down in the vertical direction, which in turn drives the square frame 54 to slide along the inside of the mounting groove 53, which drives the U-shaped connecting plate 510, the folded plate 511 and the horizontal plate 512 to move, which in turn drives the drive motor 62, the rotating tube 41 (the rotating tube 41 slides along the long shaft 31), the stirring rod 43 and the stirring plate 44 to move in the vertical direction, which facilitates the improvement of the stirring effect of the stirring mechanism 4, and makes the stirring rod 43 and the stirring plate 44 stir the raw materials more thoroughly.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
