Description

Technical Field

[0001] This utility model relates to the field of automated food processing equipment technology, and in particular to a fault self-diagnosis device for vermicelli production equipment. Background Technology

[0002] The self-diagnostic device for vermicelli production equipment is used to monitor the equipment's operating status in real time, promptly detect and alarm on faults, and ensure continuous production. During long-term operation, vermicelli production equipment is prone to problems such as worn cutting machine blades, conveyor belt slippage, motor stalling, or blockages in the feeding mechanism, leading to abnormal conditions such as broken, piled-up, or missing vermicelli. Traditional equipment lacks real-time self-diagnostic capabilities, resulting in delayed fault detection and impacting production continuity. Existing detection methods mostly use fixed sensors with non-adjustable positions, making it difficult to accurately target critical workstations and leading to a high false alarm rate.

[0003] However, due to the complex environment of fan production, the height and width of conveyor belts vary between different models or workstations. Fixed brackets cannot meet the needs of multiple scenarios, resulting in large blind spots for sensor detection, susceptibility to dust and vapor interference, high false alarm rate, and the need for disassembly and reassembly during maintenance, which is cumbersome and seriously affects the reliability and practicality of the self-inspection system.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please refer to the following: Figures 1 to 5 A self-diagnostic device for a vermicelli production equipment, comprising:

[0031] Conveyor belt body 1;

[0032] The bracket connecting plate 2 is detachably installed on the frame of the conveyor belt body 1 by multiple bolts;

[0033] Support rod 3 is fixedly connected to the surface of bracket connecting plate 2;

[0034] The adjustment mechanism includes a lifting assembly, a telescopic assembly, and a stabilizing assembly. The lifting assembly includes a lifting block 401, a first rotary knob 402, a rotating rod 403, a gear 404, an adjusting groove 405, and a toothed belt 406. The lifting block 401 is slidably connected to the surface of the support rod 3. The adjusting groove 405 is formed on the surface of the lifting block 401. The rotating rod 403 is rotatably installed inside the lifting block 401. The first rotary knob 402 is fixedly connected to the end of the rotating rod 403 away from the lifting block 401. The gear 404 is fixedly connected to the circumferential surface of the rotating rod 403. The toothed belt 406 is fixedly connected to the surface of the support rod 3 and meshes with the gear 404 and the toothed belt 406. The stabilizing assembly is used to limit the movement of the lifting block 401, and the telescopic assembly is used to change the forward extension length of the device.

[0035] A clamping assembly is disposed on one side of the telescopic assembly;

[0036] The sensor is located within the clamping assembly.

[0037] In the specific implementation process, by rotating the first rotating knob 402, the rotating rod 403 is driven to rotate, causing the gear 404 to rotate accordingly. Since the gear 404 meshes with the toothed belt 406 fixed on the support rod 3, the lifting block 401 will slide up and down along the support rod 3, thereby realizing the adjustment of the sensor installation height to adapt to the height requirements of different equipment, ensuring accurate detection angle. After the adjustment is completed, the rotation stops to prepare for subsequent fixing.

[0038] refer to Figures 1 to 5 As shown, the stabilizing component includes a second rotary knob 501 and a first threaded rod 502. One end of the second rotary knob 501 is threaded through the lifting block 401 and abuts against the support rod 3. The second rotary knob 501 is fixedly connected to the other end of the first threaded rod 502.

[0039] In the above embodiment, after the lifting block 401 is adjusted to a suitable height, the second rotary knob 501 is manually tightened, causing the first threaded rod 502 to be screwed into the lifting block 401 and pressed against the surface of the support rod 3. The position of the lifting block 401 is locked by friction, preventing it from sliding down due to vibration or its own weight during use, ensuring that the sensor always maintains a stable height during operation, and improving the reliability of detection.

[0040] refer to Figures 1 to 5 As shown, the telescopic assembly includes a sleeve rod 601, a moving rod 602, a limiting ball 603, a spring 604, a limiting hole 605, and a placement groove 606. The sleeve rod 601 is fixedly connected to the surface of the lifting block 401, the moving rod 602 is slidably connected to the inner wall of the sleeve rod 601, multiple limiting holes 605 are provided, and multiple limiting holes 605 are opened on the surface of the sleeve rod 601. The placement groove 606 is opened on the surface of the moving rod 602. One end of the spring 604 is fixedly connected to the inner wall of the placement groove 606, and the limiting ball 603 is fixedly connected to the other end of the spring 604, and the limiting ball 603 is slidably connected to the inner wall of the placement groove 606 and one of the limiting holes 605.

[0041] In the above embodiment, when it is necessary to adjust the forward extension length of the device, press the limiting ball 603 by hand to compress the spring 604 and retract it into the placement groove 606, thereby releasing the lock on the moving rod 602. At this time, the moving rod 602 can be pulled out or pushed in from the sleeve rod 601 to change the extension length. When it is moved to the appropriate position, make the limiting ball 603 align with the nearest limiting hole 605. The spring 604 rebounds and pushes the limiting ball 603 into the limiting hole 605, thereby achieving quick positioning and fixation. The operation is simple and labor-saving.

[0042] refer to Figures 1 to 5 As shown, the clamping assembly includes an L-shaped clamping plate 701, a third rotating torque 702, a second threaded rod 703, and a base plate 704. The base plate 704 is fixedly connected to the end of the moving rod 602 away from the sleeve rod 601. There are two L-shaped clamping plates 701, and both L-shaped clamping plates 701 are slidably connected to the surface of the base plate 704. The second threaded rod 703 is threadedly connected to the two L-shaped clamping plates 701. The second threaded rod 703 is provided with forward and reverse threads. The two L-shaped clamping plates 701 are respectively threaded to the forward and reverse threads. The third rotating torque 702 is fixedly connected to one end of the second threaded rod 703.

[0043] In the above embodiment, after the sensor is placed between the two L-shaped clamping plates 701, the third rotating torque 702 is rotated to drive the second threaded rod 703 to rotate. Since the threaded connection directions of the two L-shaped clamping plates 701 and the second threaded rod 703 are opposite, one moves to the left and the other to the right synchronously to form a counter-clamping action, firmly clamping the sensor and preventing it from loosening and falling off. When disassembling, the sensor can be quickly released by rotating in the opposite direction, which is convenient for replacing or maintaining the sensor and improves the flexibility of use.

[0044] refer to Figures 1 to 5 As shown, the surface of the support rod 3 is provided with a graduated groove 9.

[0045] In the above embodiment, the support rod 3 has a scale groove 9 on its surface. When adjusting the height of the lifting block 401, the scale groove 9 can be used to make accurate readings, which is convenient for repeatedly positioning the same height. This is especially suitable for maintaining consistency when multiple devices are debugged at the same time or when multiple shifts are operated, reducing human error and improving debugging efficiency and detection accuracy.

[0046] refer to Figures 1 to 5 As shown, anti-detachment blocks 8 are fixedly connected to both ends of the base plate 704.

[0047] In the above embodiment, anti-detachment blocks 8 are provided at both ends of the base plate 704, which play a limiting role during the sliding of the L-shaped clamping plate 701 along the base plate 704, preventing the clamping plate from slipping off the base plate 704 due to excessive movement, ensuring that the clamping structure is always within the effective working range, enhancing the stability and safety of the overall structure, and avoiding equipment failure or detection failure due to component detachment.

[0048] refer to Figures 1 to 5 As shown, the sensor is a photoelectric sensor used to detect broken or blocked strands of vermicelli.

[0049] In the above embodiment, the sensor is a photoelectric sensor used to detect the presence and continuity of the fan flow; when the sensor does not receive an obstruction signal within a set time, or when the continuous obstruction time exceeds a threshold, it outputs a fault signal to indicate that the equipment has a cutting abnormality, the conveyor belt stops or the feeding is blocked.

[0050] The working principle of the self-diagnosis device for vermicelli production equipment provided by this utility model is as follows:

[0051] This device is compatible with different models of vermicelli production equipment, and is especially suitable for online monitoring of drying, cooling, or cutting sections. In use, firstly, rotating the first rotary knob 402 drives the rotating rod 403 to rotate, causing the gear 404 to mesh with the toothed belt 406. This, in turn, causes the lifting block 401 to slide up and down along the support rod 3, allowing for flexible adjustment of the sensor's installation height. Combined with the scale groove 9, precise readings and positioning are possible. Then, pressing the limit ball 603 compresses the spring 604 and retracts it into the placement groove 606, releasing the lock on the moving rod 602. The moving rod 602 can then be pulled out or pushed in from the sleeve rod 601 to adjust its extension length. When it reaches the appropriate position, the limit ball 603 aligns with the nearest limit hole 605. The spring 604 rebounds, pushing the limit ball 603 into the limit hole 605 to complete the locking. Finally, the sensor is placed between the two L-shaped clamping plates 701, and the third rotary knob is rotated... 702 drives the second threaded rod 703 to rotate. Because the threads of the two L-shaped clamping plates 701 and the second threaded rod 703 are opposite, they achieve synchronous opposing clamping, firmly fixing the sensor. Finally, tightening the second rotating knob 501 causes it to drive the first threaded rod 502 to press against the surface of the support rod 3, preventing the lifting block 401 from sliding. The overall structure is stable and reliable. The entire device can quickly complete alignment according to the height and space requirements of different equipment, avoiding detection blind spots and dust and vapor interference, reducing the false alarm rate. During maintenance, the locking parts can be loosened for disassembly and replacement, making operation simple. The sensor is photoelectric and is specifically used to detect broken and blocked vermicelli. During normal operation, the vermicelli periodically blocks the beam, which the system judges as normal. When there is continuous no blockage (broken vermicelli) or long-term blockage (accumulation), it indicates that the upstream equipment, such as the cutting machine or conveyor belt, has malfunctioned, and the system automatically alarms, realizing indirect "self-checking" of the equipment. It effectively solves the problems of difficult adjustment, poor adaptability, low detection accuracy, and cumbersome maintenance of traditional fixed sensor brackets, significantly improving the reliability and practicality of the fault self-checking system.
