Description

Technical Field

[0001] The utility model relates to the technical field of conveyor stock interruption monitoring equipment, and particularly relates to a stock interruption monitoring device for a belt conveyor. Background Technique

[0002] The stock interruption monitoring of a belt conveyor refers to the situation of timely detecting the interruption of materials (i.e., "stock interruption") during the operation of the belt conveyor through various detection means, and taking corresponding measures to avoid equipment failures or production interruptions. Stock interruption monitoring is crucial for ensuring the stable operation of the conveying system. 1. Prevent equipment damage: Timely detection of stock interruption can avoid the wear and damage caused by the idling of the conveyor belt. 2. Ensure production continuity: Stock interruption monitoring can timely remind the operator to supplement materials and prevent production interruptions. 3. Improve efficiency: By monitoring the stock interruption situation, the material supply can be optimized and the conveying efficiency can be improved.

[0003] Methods of stock interruption monitoring: 1. Photoelectric sensor: Principle: Utilize the photoelectric sensor to detect the presence or absence of materials. Working mode: When the material passes through the sensor, it will block the light, and the sensor judges whether there is material passing through by detecting the change of the light signal. Applicable scenario: Applicable to the detection of transparent or semi-transparent materials. 2. Ultrasonic sensor: Principle: Utilize the ultrasonic reflection principle to detect the distance of materials. Working mode: The sensor emits ultrasonic pulses, which are reflected back when encountering materials, and the sensor judges the presence of materials by measuring the round-trip time. Applicable scenario: Applicable to the detection of various solid materials. 3. Infrared sensor: Principle: Utilize the absorption or reflection of infrared rays to detect materials. Working mode: The sensor emits infrared rays, and when the material passes through, it will reflect or absorb the infrared rays, and the sensor judges whether there is material by detecting the signal change. Applicable scenario: Applicable to the detection of non-metallic solid materials. 4. Weight sensor (load cell): Principle: Judge whether there is stock interruption by detecting the weight of materials on the conveyor belt. Working mode: Installed under the conveyor belt or on the idler, when the material weight is lower than the set threshold, an alarm is triggered. Applicable scenario: Applicable to occasions where accurate weighing of material weight is required. 5. Proximity switch: Principle: Utilize electromagnetic induction or capacitance effect to detect materials. Working mode: The proximity switch triggers a signal when approaching the material, and judges the presence of materials by detecting the change of the signal. Applicable scenario: Applicable to the detection of metal materials. Composition of the stock interruption monitoring system: 1. Detection element: Various sensors or switches mentioned above. 2. Signal processor: Process the signals collected by the detection element to judge whether there is stock interruption. 3. Alarm system: When stock interruption is detected, remind the operator through audible and visual alarms, etc. 4. Control system: Connected to the conveyor control system, and can automatically stop or start standby equipment when necessary. By reasonably selecting and using stock interruption monitoring technologies, the operation efficiency and safety of the belt conveyor can be effectively improved, and production accidents caused by stock interruption can be reduced.

[0022] Hereinafter, the technical solutions in the embodiments of the present utility model will be further described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 - 4 shown, a material breakage monitoring device of a belt conveyor includes a support 1, a support rod 3, a monitoring plate 4, a sleeve 5, a recognition plate 6, an adjusting plate 7, and a proximity sensor 9. The support rod 3 is horizontally installed above the belt conveyor 10 through the support 1. A conveyor belt 11 is provided on the belt conveyor 10, and materials 12 are conveyed on the conveyor belt 11. The support rod 3 is horizontally arranged above the conveyor belt 11.

[0024] A proximity sensor 9 is installed in the middle of the support rod 3. The proximity sensor 9 is connected to a collection device and uploaded to a monitoring system. A recognition plate 6 is provided at the recognition end of the proximity sensor 9. The proximity sensor 9 is fixedly installed on the support rod 3 through a mounting plate.

[0025] Both sides of the support rod 3 are provided with threaded rods. The threaded rods pass through the U-shaped grooves at the upper part of the bracket 1. Nuts 2 are screwed onto the threaded rods 3, and the support rod 3 is fixedly installed on the bracket 1 by the nuts 2. The lower parts of the two sides of the bracket 1 are fixedly installed on the two side frames of the belt conveyor 10.

[0026] The identification plate 6 is rotatably installed on the support rod 3. The bottom of the identification plate 6 is fixedly connected to a sleeve 5. The sleeve 5 is movably sleeved on the support rod 3. The lower part of the sleeve 5 is fixedly connected to a monitoring plate 4. The lower part of the monitoring plate 4 is connected to an adjusting plate 7 through a bolt pair 8. The adjusting plate 7 contacts the conveyed material 12 on the conveyor belt 11.

[0027] A retaining ring is installed on the support rod 3. The sleeve 5 is located between the retaining ring and the mounting plate, and the sleeve 5 rotates on the support rod 3.

[0028] One side of the plate surfaces of the monitoring plate 4 and the adjusting plate 7 faces the material running direction of the belt conveyor 10.

[0029] The identification plate 6 is a sector plate, and the fan-shaped surface of the sector plate faces the proximity sensor 9.

[0030] The manufacturing principle of the present utility model:

[0031] A U-shaped groove is provided above the bracket 1. The support rod 3 is installed in the U-shaped groove and connected by the nut 2. The lower part of the bracket 1 is provided with a connecting plate connected to the frame of the belt conveyor 10; a proximity sensor mounting plate is provided on the support rod 3, and a retaining ring is provided. The sleeve 5 is installed between the proximity sensor mounting plate and the retaining ring and can freely rotate around the support rod 3; the identification plate 6 is provided with a fan-shaped surface to provide the induction surface required by the proximity sensor 9. A long hole is provided at the lower part of the detection plate 4 and connected to the adjusting plate 7. The long hole facilitates adjusting the height of the adjusting plate 7; the proximity sensor 5 transmits a signal when the sector plate moves away; the bolt pair 8 connects the monitoring plate 4 and the adjusting plate 7; the adjusting plate 7 is also provided with a long hole, and the long holes of the detection plate 4 and the adjusting plate 7 facilitate adjusting the height of the adjusting plate 7.

[0032] The present utility model is installed on the frame of the belt conveyor 10 through the bracket 1. In the case of no material flow, the monitoring plate 4 and the adjusting plate 7 are vertically downward under the action of gravity. The fan-shaped surface provided on the identification plate 6 coincides with the proximity sensor 9. At this time, the proximity sensor 9 receives a signal of material breakage; when the belt conveyor 10 is carrying the material 12, the adjusting plate 7 contacts the material 12. Under the interaction of forces, the monitoring plate 4 and the identification plate 6 rotate around the support rod 3 in a circular motion, causing the fan-shaped surface on the identification plate 6 to separate from the proximity sensor 9. At this time, the signal of the proximity sensor 9 changes, and the signal is set as material supply. At the same time, if you want to monitor the material flow conditions of different thicknesses, you only need to change the area of the fan-shaped surface on the identification plate 6 and / or adjust the height of the adjusting plate 7.
