Description

Technical Field

[0001] This utility model relates to the field of gypsum powder production technology, specifically to a vibrating feeder for producing gypsum powder. Background Technology

[0002] In the production of gypsum powder, gypsum ore needs to be crushed and ground. A vibrating feeder is used to feed gypsum ore before the crusher. It can uniformly, regularly, and continuously feed lumpy and granular gypsum ore from the storage silo into the crusher, providing a stable material supply for subsequent crushing and grinding processes. It can also perform preliminary screening of the material, improving production efficiency.

[0003] Chinese Patent Announcement No. CN220719849U discloses a vibrating feeder for producing gypsum powder, including a feeding trough. A fixed frame is snapped onto the inner wall of the feeding trough, and a limit rod is fixedly connected to the bottom of the fixed frame. Bolts are threaded into the internal part of the fixed frame. A blade groove is formed at the bottom of the inner wall of the feeding trough, and a lifting frame is provided at the bottom of the feeding trough. This utility model has the following advantages and effects: When the ore is too large, it is blocked by the limit rod. The hydraulic cylinder extension rod extends downward, and the pressure plate presses down, squeezing the top of the ore. At the same time, the lifting frame rises upward, and the blade extends upward from the blade groove, squeezing the bottom of the ore while rotating and cutting. Since gypsum ore has low hardness and is brittle, it breaks under the squeezing and cutting. After breaking, it is easy to pass through the gap of the limit rod, avoiding the difficulty of further crushing due to the large volume of the ore. It also facilitates the pre-treatment of the ore during feeding.

[0004] In the existing technology, a vibrating feeder for producing gypsum powder only uses mechanical structures such as limit rods and blades to simply squeeze and cut oversized ore. Its function is relatively simple and it is not convenient to make fine adjustments according to different production conditions and material characteristics, so it cannot meet the requirements of complex production processes. Therefore, we have made improvements and proposed a vibrating feeder for producing gypsum powder. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3 A vibrating feeder for producing gypsum powder includes a housing 1, a base 4 at the bottom of the housing 1, a base 2 inside the housing 1, a conveying plate 3 rotatably connected to the top of the base 2 via a rotating shaft, two vibrating motors 5 embedded in the top of the housing 1, the output ends of the two vibrating motors 5 being fixedly connected to the base 2, a top plate 6 fixedly installed on the top of the conveying plate 3, multiple rotating rods 7 arranged on the side of the conveying plate 3 and the top plate 6 that are close to each other, the multiple rotating rods 7 being inserted into the interior of the top plate 6 and slidably connected thereto, a first servo motor 10 arranged on the top of each of the multiple rotating rods 7, the output ends of the multiple first servo motors 10 being fixedly connected to the rotating rods 7, a crushing roller fixedly installed on the outer side of each of the multiple rotating rods 7, and an auxiliary structure arranged inside the top plate 6.

[0034] In this embodiment of the utility model, two vibrating motors 5 operate, and their output ends drive the base 2 to generate high-frequency vibration. Since the top of the base 2 is rotatably connected to the conveying plate 3 through a rotating shaft, the vibration is transmitted to the conveying plate 3. Under the combined action of vibration inertia and gravity, the gypsum ore on the conveying plate 3 moves forward in a parabolic trajectory towards the discharge end, thus realizing the initial conveying of the material.

[0035] Simultaneously, the first servo motor 10 operates, and its output shaft drives the rotating rod 7 to rotate at high speed. The crushing roller on the outer side of the rotating rod 7 rotates accordingly under the action of the bearing. The crushing teeth on the surface of the crushing roller contact the gypsum ore, squeezing, tearing and grinding the ore. For larger ore, the crushing roller, driven by the rotating rod 7, crushes it into smaller particles through the interlocking of the crushing teeth. For ore blocks that are stuck together, the rotation of the crushing roller can separate them.

[0036] Example 2: Please refer to the appendix of the instruction manual. Figure 1-4In a preferred embodiment of the present invention, the top plate 6 has two first mounting plates 8 and a second mounting plate 9 slidably connected inside. Multiple rotating rods 7 are respectively inserted into the two first mounting plates 8 and the second mounting plate 9 and rotatably connected to them. Multiple first servo motors 10 are respectively fixedly connected to the top plate 6, the first mounting plates 8 and the second mounting plates 9.

[0037] The auxiliary structure includes two first racks 11 and a second rack 12. The two first racks 11 and the second rack 12 are fixedly connected to two first mounting plates 8 and a second mounting plate 9, respectively. The two first mounting plates 8, the second mounting plate 9, the first racks 11 and the second rack 12 are all slidably connected to the top plate 6. One side of each of the two first racks 11 and the second rack 12 is meshed with a gear 13. The top of each of the gears 13 is fixedly mounted with a worm gear 16. The inside of the top plate 6 is fixedly mounted with a second servo motor 14. The output end of the second servo motor 14 is fixedly mounted with a worm 15. The worm 15 meshes with the multiple worm gears 16. The worm 15, the worm gears 16 and the gears 13 are all rotatably connected to the top plate 6.

[0038] Multiple slide plates 23 are slidably connected to the top of the conveyor plate 3, and multiple rotating rods 7 are inserted into the slide plates 23 for rotational connection.

[0039] Shock-absorbing pads are fixedly installed on both sides of the base 4 near the housing 1. Multiple insertion rods 17 are provided on the side of the base 4 near the housing 1 and on the corresponding sides of the housing 1. The multiple insertion rods 17 are fixedly connected to the base 4. The multiple insertion rods 17 are inserted into the interior of the housing 1 and slidably connected to it. The multiple insertion rods 17 pass through the rubber pad and are fixedly connected to it.

[0040] Multiple dampers 18 are embedded in the top of the base 4. The output ends of the multiple dampers 18 are fixedly connected to the housing 1. Shock-absorbing springs 19 are provided on the outside of the multiple dampers 18. The two ends of the multiple shock-absorbing springs 19 are fixedly connected to the housing 1 and the base 4 respectively.

[0041] Two guide plates 21 are provided between the inner walls of the two sides of the housing 1. Side plates 22 are fixedly installed on both sides of the two guide plates 21. Multiple side plates 22 are inserted into the interior of the housing 1 and slidably connected thereto. Multiple fixing bolts are provided on the side of the multiple side plates 22 away from the housing 1. Multiple fixing bolts penetrate the side plates 22 and are threadedly connected thereto. Multiple fixing bolts are inserted into the interior of the housing 1 and are threadedly connected thereto.

[0042] Inclined plates 20 are fixedly installed on both sides of the top of the conveyor plate 3. Both inclined plates 20 are slidably connected to the housing 1. A controller 24 is embedded on one side of the housing 1. The controller 24 is electrically connected to the vibration motor 5, the first servo motor 10 and the second servo motor 14.

[0043] In this embodiment of the utility model, since the gear 13 meshing on one side of the second rack 12 has twice the diameter of the gear 13 on one side of the first rack 11, when the gear 13 rotates, the gears 13 with different diameters mesh with the rack and generate different linear velocities. However, through the special structural design of the two first mounting plates 8 and the second mounting plate 9 symmetrically arranged, the first mounting plates 8 and the second mounting plates 9 located on the same side can rotate synchronously and in the same direction. During the rotation of the gear 13, the distance that the larger diameter gear 13 drives the second rack 12 to move and the distance that the smaller diameter gear 13 drives the first rack 11 to move are precisely calculated and structurally matched. Combined with the symmetrical mounting plate layout, the synchronous adjustment of the spacing between multiple rotating rods 7 is finally achieved.

[0044] The second servo motor 14 drives the worm gear 15 to start rotating. The worm gear 15 meshes with the worm wheel 16, transmitting the rotational motion to the worm wheel 16, which in turn drives the gear 13 fixed on the top of the worm wheel 16 to rotate. The gear 13 meshes with the first rack 11 and the second rack 12. As the gear 13 rotates, the first rack 11 and the second rack 12 respectively drive the first mounting plate 8 and the second mounting plate 9 fixed to them to slide in opposite directions within the top plate 6. Since the rotating rods 7 are inserted into and rotatably connected to the first mounting plate 8 and the second mounting plate 9 respectively, the spacing of all the rotating rods 7 can be adjusted synchronously. As the spacing of the rotating rods 7 changes, the spacing between the crushing rollers also changes accordingly, accurately adapting to the current ore particle size and achieving more efficient crushing and pretreatment of materials.

[0045] In this embodiment of the invention, the shock-absorbing pad first provides initial buffering for the vibration between the housing 1 and the base 4. The insert rod 17 is inserted into the housing 1 and passes through the rubber pad. Through the elastic deformation of the rubber pad and the limiting effect of the insert rod 17, the excessive shaking of the housing 1 is further limited. The composite shock absorption system composed of the damper 18 and the shock-absorbing spring 19 can absorb and dissipate the vibration energy generated by the operation of the equipment. The damper 18 rapidly attenuates the vibration amplitude through the damping effect of the internal liquid; the shock-absorbing spring 19 provides elastic support force on the basis of the damper 18 to maintain the stability of the equipment.

[0046] As the connecting link between the guide plate 21 and the housing 1, the side plate 22 ensures that the guide plate 21 is securely installed inside the housing 1, enabling the guide plate 21 to reliably perform its functions of material guidance and structural support. At the same time, the detachable fixing method facilitates the installation, commissioning and subsequent maintenance of the equipment. When the guide plate 21 or the side plate 22 is damaged, it can be quickly disassembled and replaced.

[0047] The controller 24 is the core control unit of the vibrating feeder. Two angle sensors are embedded in one side of the inner wall of the housing 1. The controller 24 is connected to the vibrating motor 5 through a power cable and a control signal line to control its vibration intensity and frequency. It is connected to the first servo motor 10 and the second servo motor 14 through a servo driver and a communication cable to control the rotation and spacing adjustment of the rotating rod 7, and to monitor and adjust in real time based on the encoder feedback signal. It is connected to the hydraulic cylinder through a hydraulic control valve and a control cable, and, combined with the feedback from the angle sensor, precisely adjusts the tilt angle of the conveyor plate 3.

[0048] Example 3: Please refer to the appendix of the instruction manual. Figure 5 In a preferred embodiment of this utility model, an auxiliary plate is slidably connected inside the base 2, and two support plates are provided above the auxiliary plate. A first auxiliary block and a second auxiliary block are rotatably connected to both sides of the two support plates via a rotating shaft. Two hydraulic cylinders are fixedly installed inside the base 2, and the output ends of the two hydraulic cylinders are fixedly connected to the auxiliary plate. The two first auxiliary blocks are fixedly connected to the auxiliary plate, and the two second auxiliary blocks are inserted into the inside of the conveying plate 3 and slidably connected thereto. Two guide rods are fixedly installed inside the conveying plate 3, and the two guide rods pass through the two second auxiliary blocks and slidably connected thereto. The two hydraulic cylinders are electrically connected to the controller 24.

[0049] In this embodiment of the utility model, the piston rods of the two hydraulic cylinders extend or retract synchronously, pushing the auxiliary plate to slide inside the base 2. The movement of the auxiliary plate is driven by the linkage of the support plate, the first auxiliary block and the second auxiliary block, which drives the conveying plate 3 to rotate around the rotating shaft connected to the base 2. Under the guidance of the guide rod, the conveying plate 3 smoothly adjusts the tilt angle, thereby changing the material conveying path and speed to meet the needs of different production conditions.

[0050] In this embodiment of the utility model, the linkage design of the hydraulic cylinder with auxiliary plate, support plate and other components gives the conveying plate 3 a flexible angle adjustment capability, which makes it easy to adjust the tilt angle of the conveying plate 3 in real time according to the material characteristics such as humidity, viscosity and the feeding requirements of subsequent equipment. At the same time, the device is provided with heat dissipation holes that cooperate with the motor to facilitate the heat dissipation of the motor.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
