Description

TECHNICAL FIELD

[0001] The utility model relates to the field of feeding equipment, and specifically relates to a rotary type quantitative feeder for block feeding. BACKGROUND

[0002] At present, in cement, steel and other manufacturing industries, limestone is an essential raw material, and limestone is crushed into block materials of a certain size for use. After the block materials are fed out through the silo, they are generally sent into the feeder for conveying. In the prior art, a screw feeder or a belt feeder is generally used to convey the block materials, but the screw feeder is difficult to convey block materials of a certain size due to the size limitation of the screw, and is prone to jamming. When the belt feeder conveys the block materials, the block materials are prone to causing the belt to wear and tear, and the service life is short. At the same time, when the block materials are fed, it is difficult to accurately weigh the weight of the block materials, resulting in difficulty in quantitative feeding. SUMMARY

[0003] The utility model solves the technical problem of providing a rotary type quantitative feeder for block feeding, which can convey block materials and quantitatively feed the block materials.

[0004] To solve the above technical problems, the utility model includes a rack, and the structural characteristics are that: a fixed cylinder capable of swinging under the influence of the gravity of the block materials is installed on the rack, the fixed cylinder is a cylindrical body, an upper feeding port for feeding is arranged at the upper end of the fixed cylinder, and a lower discharging port for discharging is arranged at the lower end of the fixed cylinder, the upper feeding port is located on one side of the fixed cylinder, and the lower discharging port is located on the other side of the fixed cylinder, a rotating cylinder capable of rotating in the fixed cylinder is arranged in the fixed cylinder, the rotating cylinder can move the block materials falling from the upper feeding port to the lower discharging port, a speed measuring device capable of measuring the rotating speed of the rotating cylinder is arranged on the rack, and a weighing device capable of measuring the weight of the block materials in the fixed cylinder is arranged on the rack.

[0005] After the above structure is adopted, the block materials enter the fixed cylinder through the upper feeding port, the rotation of the block materials in the fixed cylinder is driven by the rotating cylinder, the block materials are rotated to the lower discharging port, and then fall from the lower discharging port, thereby completing the conveying of the materials. The weight of the block materials is weighed by the weighing device, the rotating speed of the rotating cylinder is measured by the speed measuring device, the rotating speed of the materials is obtained, the time when the materials enter the lower discharging port is obtained, and then the total amount of the materials falling from the lower discharging port within a certain time can be obtained. When the total amount of the materials falling reaches the required amount, the rotating cylinder stops rotating, and the block materials no longer fall into the lower discharging port, thereby realizing the quantitative feeding of the block materials, facilitating the next process, and improving the efficiency.

[0006] The rack is provided with a vertical rotating shaft, which is located at the axis of the fixed cylinder and the moving cylinder, and is driven to rotate by a driving device. The rotating cylinder comprises a hub and a rotating cylinder body. The hub is sleeved on the rotating shaft and can be driven to rotate by the rotating shaft. A plurality of blades are arranged between the hub and the rotating cylinder body. The blades are radially arranged sheet bodies. The plurality of blades are uniformly arranged around the hub. The outer edge diameter of the rotating cylinder body is smaller than the inner edge diameter of the fixed cylinder. The farthest distance between the feeding port and the shaft center is smaller than the inner surface diameter of the rotating cylinder body. The driving device drives the vertical rotating shaft to rotate, thereby driving the rotating cylinder to rotate along the axis of the rotating shaft in the fixed cylinder. The hub is used to mount the rotating cylinder on the rotating shaft. The blades are used to connect the block material between the rotating cylinder body and the hub. The plurality of blades reduce the pressure of one blade. The farthest distance between the feeding port and the shaft center is smaller than the inner surface diameter of the rotating cylinder body, so that the material can fall into the space between the rotating cylinder body and the hub, avoiding the block material being stuck between the rotating cylinder body and the fixed cylinder, ensuring the service life and improving the transportation efficiency and avoiding waste.

[0008] The weighing device comprises a fixed support connected with the rack and a connecting plate connected with the lower end surface of the fixed cylinder. The fixed support and the connecting plate are provided with a weighing sensor.

[0009] The feeding port is located at the left front part of the fixed cylinder, the discharging port is located at the right front part of the fixed cylinder, the moving cylinder body rotates counterclockwise, and the weighing device is located at the rear edge of the fixed cylinder. The block material enters the fixed cylinder from the left front part, rotates counterclockwise rearward, and after rotating to the weighing device, the weighing device weighs, and then moves to the discharging port for discharging, thereby ensuring accurate weighing.

[0010] The diameter of the discharge port is larger than that of the feed port, which increases the efficiency of material feeding and avoids material jamming at the discharge point, thereby improving efficiency and ensuring service life.

[0011] The speed measuring device includes a connecting disc and an encoder mounted on the rotating shaft, which measures the rotation angle of the rotating shaft, thereby determining the movement angle of the block material inside the fixed cylinder, and the time it takes for the block material to move to the discharge port. Through the cooperation of the speed measuring device and the weighing device, the total amount of falling material is measured, thereby controlling the rotating cylinder to achieve the purpose of quantitative material feeding.

[0012] In summary, this utility model has the advantages of being able to convey block materials and feed them quantitatively, with high efficiency, good safety, and long service life. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model;

[0014] Figure 2 for Figure 1 A schematic diagram of the structure viewed from the left. Detailed Implementation

[0015] like Figure 1 , 2 As shown, this utility model is a rotary quantitative feeder for feeding block materials, which includes a frame 1, a fixed cylinder 2 capable of swinging back and forth mounted on the frame 1, and a rotating cylinder 5 capable of rotating within the inner cavity of the fixed cylinder 2. For ease of description, let... Figure 1 Left is left, right is right, let's assume... Figure 1 The direction perpendicular to the paper inwards is considered "front," and the direction perpendicular to the paper outwards is considered "back." The frame 1 is equipped with a speed measuring device to measure the rotational speed of the rotating drum 5 and a weighing device 6 to weigh the material inside the fixed drum 2. The fixed drum 2 has an inlet on one side above the rotating drum 5 for placing the material into the rotating drum 5, and an outlet on the other side below the fixed drum 2. The material enters the rotating drum 5 inside the fixed drum 2 through the inlet, and is then moved by the rotating drum 5 to the outlet side before exiting. The weighing device 6 measures the weight of the material inside the fixed drum 2, and the speed measuring device determines the time it takes for the weighed material to rotate to the outlet. Therefore, the weighing device 6 and the speed measuring device can determine the amount of material discharged from the outlet within a certain time. After the data from the weighing device 6 and the speed measuring device are fed back to the control device, the control device determines that the amount of material discharged from the outlet matches the required amount. The control device then transmits a signal to control the rotating drum 5, stopping its rotation and thus stopping the material discharge, achieving the purpose of quantitative feeding.

[0016] like Figure 1 , 2As shown, the fixed cylinder 2 is a cylindrical cylinder, which includes a fixed cylinder body 21, an upper top plate 22, and a lower bottom plate 23. The fixed cylinder body 21 is a cylindrical tubular body. The axis of the fixed cylinder 2 is provided with a rotating shaft driven by a driving device. The driving device can be a motor, which transmits power to the speed reducer through the motor, and the speed reducer is connected to the rotating shaft, thereby driving the rotation of the rotating shaft. The rotating cylinder 5 is installed in the fixed cylinder 2, and the rotating cylinder 5 includes a hub, a rotating cylinder body 51, and a plurality of blades 52 installed between the hub and the rotating cylinder body 51. The blades 52 are arranged along the axis of the rotating cylinder 5, and the plurality of blades 52 are uniformly arranged around the hub. The rotating cylinder body 51 is a cylindrical tubular body, and the axis of the rotating cylinder body 51 overlaps the axis of the fixed cylinder 2, so that the axis of the rotating cylinder body 51 is at the hub. The lower surfaces of the rotating cylinder body 51, the hub and the blades 52 are flush. In this embodiment, the height of the top of the blade 52 is 100-300mm lower than the top of the rotating cylinder body 51. While ensuring the rotation of the block, the difficulty of the block entering the rotating cylinder 5 is reduced, and the block is prevented from being jammed. The outer surface diameter of the rotating cylinder body 51 is smaller than the inner surface diameter of the fixed cylinder 2, so that the rotating cylinder body 51 can rotate in the fixed cylinder body 21. In this embodiment, a gap is left between the rotating cylinder body 51 and the fixed cylinder body 21, and the gap is 10-30mm. The movement of the rotating cylinder body 51 is facilitated, friction is avoided, and the waste of space caused by the too large gap is avoided. The farthest distance between the feeding port 3 and the axis is smaller than the inner surface diameter of the rotating cylinder body 51. When the block falls from the feeding port 3 into the fixed cylinder 2, it falls into the space formed by the rotating cylinder body 51 and the hub, and then the block is moved in the fixed cylinder 2 by the blade 52, so that the block is scraped and falls at the discharging port 4. The diameter of the discharging port 4 is larger than that of the feeding port 3, so that more material can fall from the discharging port 4, the block at the corner is prevented from being jammed, the waste of the block is avoided, and the economic benefit is improved.

[0017] As Figure 1 , 2As shown, the rack 1 is provided with a support device for installing and supporting the fixed cylinder 2. The support device is located on the left and right sides of the fixed cylinder 2, and the two support devices are symmetrically arranged. The support device includes a first support body 71 mounted on the robot and a second support body 72 mounted on the fixed cylinder 2. The second support body 72 is placed on the upper side of the first support body 71, and the upper part of the first support body 71 is a cone. The lower end of the second support body 72 is provided with a conical hole, and the angle of the hole bottom of the conical hole of the second support body 72 is greater than the taper of the first support body 71. The cone of the first support body 71 penetrates into the conical hole of the second support body 72. Since the angle of the conical hole is greater than the angle of the cone, the angle of the second support body 72 changes with the change of the center of gravity of the fixed cylinder 2, until the side surface of the conical hole contacts the cone, and then the fixed cylinder 2 swings along the straight line formed by the two support devices. In this embodiment, the feeding port 3 is located at the left front of the upper top plate 22 of the fixed cylinder 2, and the discharging port 4 is located at the right front of the lower bottom plate 23. The rotating cylinder 5 drives the block to rotate counterclockwise to the discharging port 4. When the block rotates to the rear end of the fixed cylinder 2, the rear side of the fixed cylinder 2 is downwardly offset, and the front side is upwardly offset. The weighing device 6 is located at the rear side of the fixed cylinder 2, and the weight of the block in the fixed cylinder 2 is weighed by the weighing device 6.

[0018] As shown in Figure 1 , 2 , the weighing device 6 includes a fixed bracket 61 mounted on the rack 1 and a connecting plate 62 connected to the lower end surface of the fixed cylinder 2. The fixed bracket 61 and the connecting plate 62 are provided with a weighing sensor 63 therebetween. The height of the fixed bracket 61 is higher than that of the connecting plate 62. When the block moves to the weighing device 6, the gravity of the block drives the fixed cylinder 2 to swing. At this time, the weighing sensor 63 bears the gravity of the block, so that the fixed cylinder 2 remains stable and does not further incline downward, and thus the weight of the block located on one side of the fixed cylinder 2 is measured. The weighing device 6 is simple and convenient to set, and accurately measures the weight of the block, thereby realizing the quantitative feeding of the block and achieving the demand. In this embodiment, the weighing device 6 is located at the position 200° clockwise rotated from the feeding port 3 of the fixed cylinder 2. The speed measuring device includes a coupling disc and an encoder sleeved on the rotating shaft. Through the coupling disc and the encoder, the driving speed of the rotating shaft is obtained, and then the rotation angle of the block is obtained, and then the falling time of the block from the discharging port 4 is obtained. Through the data of the speed measuring device and the weighing device 6, the amount of the block falling from the discharging port 4 is obtained, and then fed back to the control system. The rotation of the rotating shaft is controlled through the control system, and then the falling amount of the block is controlled, so as to achieve the purpose of quantitative feeding.
