Description

Technical Field

[0001] The utility model relates to the technical field of control of industrial conveying equipment, and more specifically, to an electric cylinder type belt deviation detection and automatic deviation correction device. Background Art

[0002] In industrial production and processing, belt conveyors are often used as conveying equipment for processing materials. They have the characteristics of stable conveying, easy maintenance and repair, simple installation and use. The belt conveyor structure in the prior art includes a belt conveyor body, a sealing skirt, a transmission motor, a conveying belt, an active roller, a passive roller, a tensioning roller, etc. Among them, the conveying belt drives the active roller at the front end to operate through the transmission motor, so that the active roller can move with the movement of the transmission motor. When the conveying belt is running, the tensioning roller tightens the conveying belt to the passive roller, thereby driving the passive roller to operate synchronously, so as to achieve the operation of the belt conveyor and the function of conveying materials.

[0003] In actual use, due to the long length of the conveyor belt used in the belt conveyor, in order to ensure that the belt movement is coaxial with the central axis of the belt conveyor body during movement, to avoid the belt movement from being offset or skewed, resulting in belt wear, scraping the side plate of the belt conveyor, and causing material leakage during material transportation, it is necessary to observe the belt running deviation at any time, adjust the tensioning roller in time, and use the tensioning roller to constrain the belt movement trajectory and center it. However, the conveyor belt deviation needs to be observed from time to time. When the deviation becomes more serious, it will curl up until it is close to the side wall of the belt conveyor, which will eventually make the belt unusable and can only be replaced with a new belt. Because the high-speed belt is a closed device and the front and rear equipment are compactly installed, it is extremely difficult to replace, which is time-consuming and labor-intensive. In response to the deviation of the belt conveyor belt, it is necessary to observe and adjust it from time to time. Some companies adopt the method of regular maintenance, manual observation of belt movement and constant adjustment.

[0004] The problem of belt deviation can be solved by regularly observing the belt and adjusting it manually. However, industrial manufacturing enterprises use a large number of belt conveyors over a wide range of applications. Manual inspection and adjustment is time-consuming and laborious. Some belt conveyors have insufficient space for maintenance and observation, making manual adjustment difficult. Utility Model Content

[0005] One purpose of the utility model is to provide an electric cylinder type belt deviation detection and automatic deviation correction device to solve the above-mentioned problems of frequent conveyor belt deviation, high manpower adjustment cost and great maintenance effort.

[0006] According to the first aspect of the utility model, there is provided an electric cylinder type belt deviation detection and automatic deviation correction device, comprising a metal detection sensor, an embedded metal sheet and a controller, wherein the metal detection sensor is electrically connected to the electric cylinder, the metal detection sensor and the electric cylinder are electrically connected in series and then electrically connected to the controller, the embedded metal sheet is embedded in one side of the conveyor belt, the position of the embedded metal sheet is detected by the metal detection sensor, and the controller controls the extension and retraction action of the electric cylinder according to the real-time position of the embedded metal sheet.

[0007] Optionally, the electric cylinder is connected to a suspended tensioning roller via a tensioning roller lock, and the telescopic movement of the electric cylinder is transmitted to the suspended tensioning roller via the tensioning roller lock, thereby adjusting the tension of the conveyor belt.

[0015] The electric cylinder belt deviation detection and automatic deviation correction device disclosed in the present invention has the following technical effects:

[0016] The metal detection sensor is electrically connected to the electric cylinder, and then connected in series to the controller. The embedded metal sheet is fixed to one side of the conveyor belt by screws to ensure the effectiveness of deviation detection. When the conveyor belt moves, it drives the embedded metal sheet to move. The embedded metal sheet is detected by the metal detection sensor. If the position deviation of the embedded metal sheet exceeds the belt deviation limit, the metal detection sensor has no signal feedback, indicating that the belt is deviating; if the metal detection sensor does not detect the signal of the embedded metal sheet within 1 minute, it will feedback an adjustment signal to the controller. The controller transmits the adjustment signal to the electric cylinder, and the electric cylinder retracts to drive the suspended tension roller on one side to move, generating a deflection angle of the suspended tension roller, and using the angle deflection to correct the conveyor belt deviation.

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] In the prior art, the deviation of the conveyor belt needs to be observed from time to time. When the deviation becomes more serious, it will be close to the side wall of the belt conveyor and curl up, which will eventually make the belt unusable and have to be replaced with a new belt. Because the high-speed belt is a closed device and the front and rear equipment are compactly installed, it is extremely difficult to replace, which is time-consuming and labor-intensive. In response to the deviation of the belt conveyor belt, it is necessary to observe and adjust the situation from time to time. Some companies have adopted the method of prescribing regular maintenance, manually observing the movement of the belt and adjusting it from time to time. The utility model can detect the deviation of the conveyor belt of the belt conveyor and automatically correct the deviation. The PLC controller is used to control the angle deviation of the tensioning roller, and the electronic screen is used to manually trigger the correction and adjust the degree of correction of the correction device. In the case of the automatic correction function, an alarm is issued for the deviation of the belt, which can more accurately remind the maintenance personnel of the deviation information, accurately adjust the deviated belt conveyor, and avoid the work caused by large-scale inspections.

[0027] The utility model proposes an embodiment of an electric cylinder type belt deviation detection and automatic deviation correction device, specifically, as follows Figure 1 to Figure 2 As shown, it includes a metal detection sensor 6, an embedded metal sheet 7 and a controller. The metal detection sensor 6 is electrically connected to the electric cylinder 5. The metal detection sensor 6 and the electric cylinder 5 are electrically connected in series and then electrically connected to the controller. The embedded metal sheet 7 is embedded in one side of the conveyor belt 1. The position of the embedded metal sheet 7 is detected by the metal detection sensor 6. The controller controls the telescopic action of the electric cylinder 5 according to the real-time position of the embedded metal sheet 7. When the conveyor belt 1 moves, the metal detection sensor 6 can monitor the position change of the embedded metal sheet 7 relative to the metal detection sensor in real time. The controller receives the position of the embedded metal sheet 7 monitored by the metal detection sensor 6, and determines whether the conveyor belt is deviated according to these position signals. If the conveyor belt is deviated, the controller sends a telescopic adjustment instruction to the electric cylinder 5. The electric cylinder 5 receives the telescopic adjustment instruction from the controller, performs the telescopic action, and further drives the suspended tension roller 4 to move, thereby adjusting the running track of the conveyor belt 1. During the correction process, the metal detection sensor 6 will continue to monitor the position of the embedded metal sheet 7 and feed back the real-time position information of the embedded metal sheet 7 to the controller. The controller will determine whether the correction is successful based on the real-time position information and decide whether further adjustment is needed.

[0028] In the embodiment of the utility model, the electric cylinder 5 is connected to the suspended tensioning roller 4 through the tensioning roller lock 9, and the telescopic movement of the electric cylinder 5 is transmitted to the suspended tensioning roller 4 through the tensioning roller lock 9, so as to adjust the tension of the conveyor belt 1. The electric cylinder 5 is directly connected to the tensioning roller lock 9, and through the transmission of the tensioning roller lock 9, the telescopic movement of the electric cylinder 5 can be accurately converted into the position change of the suspended tensioning roller 4. The position change of the suspended tensioning roller 4 will directly affect the tension of the conveyor belt 1, and then adjust the running track of the belt to return it to the correct position. Through the precise transmission of the electric cylinder 5 and the tensioning roller lock 9, the position of the suspended tensioning roller 4 can be accurately controlled, thereby ensuring the accuracy and reliability of the deviation correction. The entire deviation correction process has a high degree of automation and a fast response speed, and the deviation correction operation of the conveyor belt 1 can be completed in a short time.

[0029] In the embodiment of the utility model, one end of the suspended tensioning roller 4 is connected to a fixed suspension 8, and the suspended tensioning roller 4 and the electric cylinder 5 are supported and fixed by the fixed suspension 8. The fixed suspension 8 provides stable support for the suspended tensioning roller 4 to ensure that it does not shake or move during operation. In addition to the support, the fixed suspension 8 also firmly fixes the suspended tensioning roller 4 and the electric cylinder 5 in a specified position to prevent them from unnecessary movement during the deviation correction process. Through the support and fixing effect of the fixed suspension 8, the suspended tensioning roller 4 can maintain a stable position and posture, thereby improving the stability of the entire deviation correction system.

[0030] In the embodiment of the utility model, the suspended tension roller 4 is threadedly connected and fixed to the tension roller lock 9. This connection method realizes a tight connection between the two through the screwing of the thread, ensuring that no loosening or displacement occurs during the deviation correction process.

[0031] In the embodiment of the utility model, the embedded metal sheet 7 is a rectangular structure, and the long side of the embedded metal sheet 7 is parallel to the conveying direction of the conveyor belt 1. The embedded metal sheet 7 is a rectangle with a length of 2 cm and a width of 8 cm. The size of the embedded metal sheet 7 can be adjusted according to the specific parameters of the conveyor and its conveyor belt.

[0032] In an embodiment of the utility model, a screw hole is provided on the embedded metal sheet 7, and the embedded metal sheet 7 is fixed to one side of the conveyor belt 1 by screws, and the embedded metal sheet 7 is 2 cm away from the edge of the conveyor belt 1. Specifically, there are two screw holes, and the diameter of the two screw holes is Ф2. The embedded metal sheet 7 is fixed to one side of the conveyor belt 1 2 cm away from the edge through two Ф2 screw holes to ensure the effectiveness of deviation detection. It is ensured that the embedded metal sheet 7 will not be damaged due to being too close to the edge, and it is also ensured that the metal detection sensor 6 can accurately detect the position of the embedded metal sheet 7. Using two Ф2 screws for perforation fixation is simple and effective, and can ensure a firm connection between the metal sheet and the conveyor belt. The diameter of the Ф2 screw is moderate, which can provide sufficient fixing force without causing excessive damage to the conveyor belt.

[0033] In the embodiment of the utility model, the controller is configured as a PLC controller. The PLC controller receives the position of the embedded metal sheet 7 detected by the metal detection sensor 6, and controls the electric cylinder 5 according to the position of the embedded metal sheet 7, and controls the telescopic action of the electric cylinder 5 to adjust the position of the suspended tension roller 4, thereby realizing the deviation correction operation of the conveyor belt 1.

[0034] In an embodiment of the utility model, the electric cylinder belt deviation detection and automatic deviation correction device also includes an electronic screen, and the controller is communicatively connected to the electronic screen. The controller sends the position detected by the metal detection sensor 6 and the operating status information of the conveyor belt 1 to the electronic screen through the communication interface for display. When the belt deviation is detected, the electronic screen can display an alarm message to remind the operator to pay attention and take corresponding measures. Through the electronic screen, the operator can easily set the parameters of the controller to meet different work requirements. The communication connection between the controller and the electronic screen ensures the real-time transmission of information, so that the operator can understand the operating status of the conveyor belt in a timely manner.

[0035] In an embodiment of the utility model, the electric cylinder type belt deviation detection and automatic deviation correction device also includes an audible and visual alarm, and the controller is bidirectionally electrically connected to the audible and visual alarm, and the audible and visual alarm includes an alarm light and a buzzer. It is ensured that when the controller detects the belt deviation, the audible and visual alarm can be quickly activated, so that the alarm light starts to flash and the buzzer emits a continuous sound alarm. It should be noted that when the operator confirms and handles the belt deviation, the button or switch on the audible and visual alarm is operated to inform that the abnormal situation has been handled.

The controller transmits the adjustment signal to the electric cylinder 5, and the electric cylinder 5 retracts to drive the suspension tensioning roller 4 on one side to move, generating a deflection angle of the suspension tensioning roller 4, and using the angle deflection to correct the deviation of the conveyor belt 1.
