Description

Technical Field

[0001] This utility model belongs to the technical field of chain plate conveyors, specifically relating to an anti-overflow device for chain plate material conveyors. Background Technology

[0002] In the field of material handling, chain conveyors are a commonly used conveying equipment, widely applied in various industrial production lines. During the conveying process, chain conveyors may suddenly slow down or stop due to reasons such as chain breakage or excessive wear, motor failure, sensor malfunction, brake damage or inability to transmit braking commands, or electrical circuit faults. Conversely, sudden acceleration may occur due to drive unit failure, changes in material characteristics, or changes in the operating environment. Sudden deceleration or stopping can lead to increased material accumulation on the chain conveyor, easily causing material spillage during transport. Sudden acceleration can also cause instability in the material transport process, especially at bends, where material may scatter. Therefore, during material transport, manual monitoring of the conveyor's operating status is necessary to adjust the feeder's discharge speed.

[0003] As can be seen from the above, the existing anti-overflow devices for chain plate material conveyors have the following defects when in use: First, the material supply is not easy to be automatically adjusted according to the conveying speed, and it requires continuous manual monitoring and adjustment; Second, the lack of effective material control equipment leads to uneven material levels on the chain plate conveyor, which can easily cause accumulation or shortage. When the chain plate conveyor malfunctions, it increases the probability of material scattering or overflowing during the conveying process, causing chaos in the production environment. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an anti-overflow device for chain plate material conveyors, thereby solving the problems mentioned in the background art.

It also includes a controller and a speed sensor mounted on the chain plate conveyor. The output end of the speed sensor is connected to the signal input end of the controller to provide the controller with a signal indicating the conveying speed of the chain plate conveyor. The signal output end of the controller is used to output a control signal, which is used to control the operation of the feeder.

[0006] Preferably, it also includes a barrier installed between the feed hopper and the chain conveyor, and a gate movably connected to the side of the barrier away from the feeder for controlling the opening and closing state of the feed hopper.

[0007] Preferably, the gate is hinged to the fence by a pin shaft, one end of the pin shaft is connected with a first motor output shaft fixed to one side of the fence, and the first motor drives the gate to rotate around the pin shaft under the control of the controller.

[0008] Preferably, a plurality of flat material plates are movably connected to the frame of the chain plate conveyor, and the plurality of flat material plates are equidistantly distributed on the chain plate conveyor.

[0009] Preferably, both ends of the flat material plate penetrate the frame, and a second motor connected with one end of the flat material plate is mounted on the side wall of the frame, and the second motor drives the flat material plate to move under the control of the controller.

[0010] Preferably, the alarm device connected with the controller is further included, and when the conveying speed of the chain plate conveyor detected by the speed sensor exceeds the preset range, the controller controls the alarm device to send an alarm signal.

[0011] The beneficial effects of the utility model are: the speed sensor monitors the conveying speed of the chain plate conveyor in real time, and transmits signals to the controller, and the controller automatically adjusts the operation of the feeder according to the conveying speed, so as to ensure that the material supply quantity matches the conveying speed, and prevent material overflow.

[0020] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be described in detail below in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.

[0021] The existing chain plate type material conveyor anti-overflow device mainly comprises a chain plate conveyor 1 for conveying materials, a feed hopper 2 arranged above the chain plate conveyor 1 and used for guiding the materials onto the chain plate conveyor 1, and a feeder 3 arranged above the feed hopper 2 and used for conveying the materials into the feed hopper 2, the feeder 3 can be a screw feeder 3 or a star type feeder 3 or other feeding equipment capable of uniform feeding, of course, and the feeder 3 can also be other feeding equipment capable of uniform feeding, in use, the materials to be conveyed are first stored in the material cylinder 12 above the feeder 3 (shown in the figure), during the conveying of the materials, the materials fall from the material cylinder 12 into the feeder 3, are conveyed by the feeder 3, and then uniformly fall into the feed hopper 2, and finally are guided onto the chain plate conveyor 1 along the feed hopper 2, with the running of the chain plate conveyor 1, the conveying of the materials is realized, and the above is an introduction of the existing chain plate type material conveyor anti-overflow device.

[0022] During the conveying process of the chain plate conveyor 1, the conveyor may suddenly slow down or stop running due to reasons such as chain breakage or excessive wear, motor failure, sensor malfunction, brake damage or failure of brake instruction transmission, electrical circuit failure, and the conveyor may also suddenly accelerate due to reasons such as drive device failure, change of material properties or change of running environment, sudden deceleration or pause may cause the accumulated materials on the chain plate conveyor 1 to increase, and the materials may easily overflow during the conveying process, and sudden acceleration may also cause the materials on the chain plate conveyor 1 to become unstable during the conveying process, especially at the turning part of the chain plate conveyor 1 with a curvature, the materials may easily scatter, therefore, the running state of the conveyor needs to be monitored by manpower during the conveying of the materials, so as to adjust the feeding speed of the feeder 3, as known from the above, the existing chain plate type material conveyor anti-overflow device has the following defects during use, first, the material supply amount is not convenient for automatic adjustment according to the conveying speed, and needs to be constantly monitored and adjusted by manpower, second, there is a lack of effective material control equipment, which causes the materials guided onto the chain plate conveyor 1 to be uneven, and the materials may easily accumulate or be short, when the chain plate conveyor 1 fails, the probability of scattering or overflowing of the materials during the conveying process is increased, and the production environment is chaotic, based on the above problems, the utility model adopts the following improvement mode for solution.

[0023] As Figures 1-6 shown, the chain plate type material conveying machine anti-overflow device, unlike the prior art, a speed sensor 5 is installed on the transmission shaft of the chain plate type conveyor, and a controller 4 is installed on the frame 9 of the chain plate conveyor 1, the output end of the speed sensor 5 is connected with the signal input end of the controller 4, for providing the signal of the conveying speed of the chain plate conveyor 1 to the controller 4, the controller 4 controls the operation of the feeder 3 (as Figure 1 shown, the feeder 3 of the utility model is a screw feeder 3) according to the conveying speed of the chain plate conveyor 1 monitored by the speed sensor 5, when the speed sensor 5 monitors that the rotating speed of the chain plate conveyor 1 slows down, the controller 4 controls the discharging speed of the feeder 3 to slow down accordingly, when the speed sensor 5 monitors that the rotating speed of the chain plate conveyor 1 increases, the controller 4 controls the discharging speed of the feeder 3 to speed up accordingly, specifically, according to the characteristics of the material conveyed by the chain plate conveyor 1, a rotating speed range of the chain plate conveyor 1 and the discharging speed of the feeder 3 corresponding to a rotating speed in the rotating speed range are pre-set on the controller 4, for example, the safe conveying speed range of the chain plate conveyor 1 is A-Br / min, when the speed sensor 5 monitors that the conveying speed of the chain plate conveyor 1 is A / minute, the corresponding discharging speed of the feeder 3 is at / h, when the speed sensor 5 monitors that the conveying speed of the chain plate conveyor 1 is A+1r / min, the corresponding discharging speed of the feeder 3 is a+1t / h, and the above rule is followed to match the rotating speed of the chain plate conveyor 1 (the rotating speed directly affects the moving speed of the chain plate on the driving wheel) with the discharging speed of the feeder 3, when the conveying speed of the chain plate conveyor 1 is lower than Ar / min or close to 0r / min, it indicates that the chain plate conveyor 1 has a fault, the controller 4 controls the feeder 3 to stop running, when the conveying speed of the chain plate conveyor 1 is greater than Br / min, it indicates that the chain plate conveyor 1 has a fault, the controller 4 also controls the feeder 3 to stop running, to avoid the continuous feeding of the feeder 3 leading to the overflow or scattering of the material from the chain plate conveyor 1, but in the specific application process, the specific rotating speed and the discharging speed of the feeder 3 corresponding to the rotating speed need to be determined according to the characteristics of the material, the length of the chain plate conveyor 1 and other factors, the above example is only for the technical personnel in the art to facilitate understanding of the technical solution.

[0024] Further, as Figures 2-5As shown, when the chain conveyor 1 and the feeder 3 are opened, the controller 4 controls the first motor 8 to operate, drives the shutter 7 to rotate away from the side of the fence 6, opens the inlet hopper 2, and enables the material to be directly guided to the chain conveyor 1. Correspondingly, when the controller 4 controls the feeder 3 to stop feeding, it also controls the first motor 8 to drive the shutter 7 to reset, thereby closing the inlet hopper 2. However, when the material is guided from the inlet cylinder 12 to the chain conveyor 1, the material is usually uneven, and the protruding material is easy to overflow or scatter at the bend of the chain conveyor 1 or when the chain conveyor 1 fails. In order to solve this problem, when the controller 4 controls the shutter 7 to open, it controls the first motor 8 to operate at a preset angle, thereby controlling the distance between the bottom of the shutter 7 and the upper surface of the chain conveyor 1, so as to set the required safety distance between the bottom of the shutter 7 and the upper surface of the chain conveyor 1 according to the characteristics of the material. The safety distance is the maximum thickness of the material conveyed on the chain conveyor 1, which is also the safety thickness, thereby avoiding the scattering of the material at the bend of the chain conveyor 1 or when the chain conveyor 1 fails when conveying materials with good flowability, and also avoiding the accumulation of materials when conveying materials with poor flowability.

[0025] Further, as shown in Figures 4-5 In order to avoid the accumulation of materials when conveying materials using a chain conveyor 1 with a long length, a plurality of leveling plates 10 can be equally distributed on the frame 9 of the chain conveyor 1. The two ends of the leveling plate 10 penetrate the frame 9, one end of the leveling plate 10 is connected with the second motor 11 installed on the frame 9, and the controller 4 controls the angle of operation of the second motor 11 to be the same as the angle of operation of the first motor 8, so that the leveling plate 10 rotates the same angle as the shutter 7, and the distance from the bottom of the shutter 7 to the upper surface of the chain conveyor 1 is the same as the distance from the bottom of the leveling plate 10 to the upper surface of the chain conveyor 1, thereby leveling the accumulated material during the conveying process, and further avoiding the risk of material overflow or scattering, as shown in Figure 3 The bottom of the leveling plate 10 can be provided in a rake tooth shape, which can level the material during conveying, prevent the material from piling up too high, and thereby avoid material overflow and blockage during conveying.

[0026] Further, by increasing the alarm device connected with the controller 4, in combination with the above content, when the conveying speed exceeds the preset range, the controller 4 controls the alarm device to timely send an alarm signal, reminding the operator to take corresponding measures, thereby avoiding equipment failure and safety accidents. The alarm device can be a sound and / or light alarm, which can help the operator to see in time, maintain and troubleshoot the equipment, and prolong the service life of the equipment.
