Description

Technical Field

[0001] The invention belongs to the technical field of conveying devices, and in particular relates to a stable conveying device used for processing automobile parts. Background Art

[0002] When automobile parts are being processed, conveying devices are needed to realize automatic conveying of automobile parts to reduce the time and labor intensity of manual handling. Conveying devices usually have a high transportation speed and can quickly transport parts from one location to another. This is especially important for large-scale automobile parts processing companies. For example, a new energy vehicle production parts conveying device proposed in patent publication number CN117775654A is used to solve the current problem that some impurities will remain on the parts. If the impurities are not cleaned in time, it will easily cause inconvenience to subsequent processing procedures.

[0003] Since auto parts are usually heavy, when they are transported by a conveyor, the wear of the belt on the surface of the conveyor will be accelerated. A slightly worn belt has little effect on the conveyor, but as the degree of wear increases, the belt surface will become rough and uneven, and the friction between the belt and the drive roller will increase, resulting in increased running resistance of the conveyor belt and a gradual decrease in the conveying speed. At the same time, the belt thickness will become thinner and the overall tension will change, requiring the operator to adjust the tension. In addition, the strength of a severely worn belt will be greatly reduced, and it is very easy to break when subjected to a large tensile force. Once the belt breaks, the conveyed material may scatter and injure the operator or damage the equipment. Therefore, when the operator detects the degree of belt wear, he needs to select a specific time to pause the conveying equipment and use a thickness measuring device to measure the belt thickness. If the operator fails to inspect the belt in time, the belt is at risk of breaking.

[0026] The operating principle of the present invention is now described as follows: after the conveying device is used to convey heavier automobile parts for a long time, the belt 5 of the conveying device will be worn, and the thickness of the belt 5 will become thinner, making it easier for the belt 5 to slacken during operation, affecting the conveying efficiency and stability. When the belt 5 becomes loose, the extrusion force of the upper roller 8 in contact with the upper side wall of the belt 5 by the belt 5 will also become smaller accordingly, and the upper roller 8 will drive the tension frame 7 to move downward, and as the wear of the belt 5 increases, the tension of the belt 5 will gradually decrease, and the upper roller 8 will drive the tension frame 7 to move downward. The distance between the pushbutton switch 11 and the PLC controller 12 becomes longer, and the tension frame 7 drives the conductive block 9 to move downward together until the conductive block 9 squeezes the push switch 11 during the downward movement (the pressing portion of the pushbutton switch 11 is provided with an insulating layer to prevent the conductive block 9 from directly contacting the pressing portion of the pushbutton switch 11, which poses a potential safety hazard). The pushbutton switch 11 is electrically connected to the PLC controller 12. When the pushbutton switch 11 is pressed, an electrical signal is transmitted to the PLC controller 12. After receiving the electrical signal, the PLC controller 12 transmits an external current to the conductive block 9. The conductive block 9 is electrically connected to the external power supply, and at this time the conductive block 9 is in contact with the conductive plate 10, and the conductive plate 10 is electrically connected to the positive circuit of the control motor 16. When the conductive block 9 is in contact with the external current, the external current will be transmitted to the positive circuit of the control motor 16 through the conductive block 9 and the conductive plate 10, so that the control motor 16 works, and the control motor 16 will drive the front threaded rod 15 to rotate. The front threaded rod 15 is connected to the rear threaded rod 15 through the belt 5 gear, so that the two threaded rods 15 rotate synchronously, and the two threaded cylinders 17 are driven to move synchronously through the threaded cooperation. , the two threaded cylinders 17 drive the driven roller 4 to move to the left through the mounting cylinder 18, thereby tightening the belt 5 sleeved on the outside of the driven roller 4 and the driving roller 3, so that the tension of the belt 5 becomes larger. When the tension of the belt 5 becomes larger and the belt 5 is tightened, the tight belt 5 will produce a greater upward squeezing force on the upper top roller 8, and the belt 5 will push the upper top roller 8 upward, so that the upper top roller 8 drives the tension frame 7 and the conductive block 9 to move upward together, until the conductive block 9 and the conductive plate 10 are separated, thereby disconnecting the forward circuit of the control motor 16, and the control motor 16 can be driven to rotate in the opposite direction through an external switch later; One hour after receiving the electrical signal transmitted by the push switch 11, the PLC controller 12 will detect the thickness of the belt 5, and detect it once every ten hours. When the thickness of the belt 5 needs to be detected, the PLC controller 12 will control the first electric push rod 20 to work, and the first electric push rod 20 will drive the lifting cylinder 191 to move upward through the lifting frame 21. The lifting cylinder 191 drives the lower top roller 23 to move upward through the lifting frame 21. The lower top roller 23 is located directly below the upper top roller 8. In the process of moving upward, the lower top roller 23 will The belt 5 and the upper roller 8 are squeezed, and when the lower roller 23 contacts the belt 5 and the upper roller 8, a reaction force is applied to the lower roller 23. Under the action of the reaction force, the lower roller 23 drives the lifting frame 21 to move downward relatively in the lifting cylinder 191. When the lifting frame 21 moves downward, it squeezes the control switch 24, and the control switch 24 transmits an electrical signal to the PLC controller 12. After receiving the electrical signal, the PLC controller 12 controls the first electric push rod 20 to stop moving. At this time, the upper roller 8 and The lower top roller 23 will squeeze the belt 5 under the elastic force of the spring. When the thickness of the belt 5 becomes thinner due to wear, the distance between the upper top roller 8 and the lower top roller 23 will become shorter. Under the action of the spring, the upper top roller 8 and the lower top roller 23 will move towards each other. The lower top roller 23 drives the trigger frame 27 to move upward through the lifting frame 21, the connecting ring 25 and the cross pin 26. The upper top roller 8 drives the upper trigger plate 28 and the lower trigger plate 29 to move downward through the lifting frame 21, the connecting ring 25 and the cross pin 26. When the belt 5 is worn to a certain extent, the trigger frame 27 The trigger rack 27 will contact the lower trigger plate 29, the trigger rack 27 will be electrically connected to the external power supply, the lower trigger plate 29 will be electrically connected to the indicator light 31, when the trigger rack 27 and the lower trigger plate 29 are in contact, the indicator light 31 will be powered on and illuminated, when the belt 5 is severely worn, the trigger rack 27 will contact the upper trigger plate 28, the upper trigger plate 28 will be electrically connected to the buzzer 30 through the PLC controller 12, when the trigger rack 27 and the upper trigger plate 28 are in contact, the PLC controller 12 will control the buzzer 30 to work, reminding the operator to replace the belt 5 in time; While detecting the thickness of the belt 5, the PLC controller 12 will also control the second electric push rod 321 to work. The second electric push rod 321 will drive the slide 33 and the detection plate 36 to move upward to the set position through the control frame 322 and the elastic rod, so that the detection plate 36 contacts the lower surface of the belt 5. Then the PLC controller 12 controls the third electric push rod 38 to drive the lifting plate 39 and the roller 40 to move downward through the elastic frame, so that the roller 40 contacts the upper surface of the belt 5, so that the detection plate 36 and the lower surface of the belt 5 maintain a certain extrusion pressure, and the friction between the belt 5 and the detection plate 36 is increased. Under the action of , the belt 5 will drive the detection plate 36 and the sliding block 34 to move to the left by overcoming the elastic force of the left spring. When the surface wear of the belt 5 is locally serious, the roughness of the belt 5 will increase, and the friction between the belt 5 and the detection plate 36 will also increase. The detection plate 36 will drive the sliding block 34 to continue to move to the left until the sliding block 34 is squeezed to the trigger button 37. The trigger button 37 will send an electrical signal to the PLC controller 12. After receiving the electrical signal, the PLC controller 12 will control the buzzer 30 to work, reminding the operator to replace the belt 5.
