Description

Technical Field

[0001] The invention relates to the technical field of conveyor deviation correction, in particular to an automatic centering mechanism for a conveyor belt and a centering method thereof. Background Art

[0002] In industrial production, conveyors are common conveying equipment. Their main structure is to use rollers to drive belts to transport materials. This method is widely used due to its direct and efficient advantages. However, due to the soft structure of the belt and factors such as errors during splicing, it is normal for the belt to have certain deviations. Especially for heavy-load conveyors, a centering corrector is required for continuous correction during the conveying process. The current automatic centering mechanism of the conveyor belt is not convenient for adapting, debugging, tightening and fine-tuning the belt. After long-term use, the belt's accuracy decreases and deformation occurs, resulting in different circumferences at both ends, resulting in inconsistent axial tightening of the belt on the surface of the conveyor roller, which is easy to cause gradual deviations during the operation of the belt. At the same time, the correction adjustment is not well visualized, and it is not convenient to display the belt deformation parameters. When correcting the belt, the traditional correction roller causes greater damage to the edge of the belt. At the same time, the splicing buckles of the belt are rubbed for a long time, which will also cause wear and even breakage, making it inconvenient to detect and avoid the splicing of the belt.

[0003] Therefore, we propose an automatic centering mechanism for conveyor belts and a centering method thereof. Summary of the invention

The expansion plate on the relatively loose side of the belt is expanded and adapted, with high fine-tuning accuracy. At the same time, with the detection of a pressure sensor, the adjustment is more flexible and the operation difficulty is low. The adaptation of a deformed belt also increases the service life of the belt.

[0019] The use of correction detection parts is efficient and direct in correction. At the same time, the threaded correction parts can be used to prevent damage to the belt edge. The spiral protrusions can be used to correct the deviation quickly without squeezing the belt edge. The spiral structure of the spiral protrusions can also clean impurities on the belt transmission surface.

[0020] By using splicing detection parts, the joints of the belts can be inspected, especially for belts that are connected by snap buckles or stitching. The splicing parts can be automatically controlled to avoid the threaded correcting parts from wearing the splicing parts, reducing safety hazards and providing better protection. It can prevent the correcting wheels from wearing the joints for a long time during the correction process, which may cause the belt connection strength to decrease or even break.

The belt deformation problem can be corrected in time, which is more direct and reliable. The two pressure sensors 202 are used to detect the tightening and fitting pressure difference of the belt at both ends of the transmission support roller 301 in real time, which is convenient for the staff to adjust and the digital display is more intuitive.

[0038] Among them, the transmission support member 3 includes: a transmission support roller 301, an expansion plate 302, a fine-tuning protrusion 3021, a rubber sleeve 303 and a limiting magnet 304. The transmission support roller 301 is rotatably installed on the roller frame 101; a circle of expansion plates 302 are slidably inserted on the transmission support roller 301, and the two ends of the circle of expansion plates 302 are respectively made of iron metal; two fine-tuning protrusions 3021 are fixedly installed on the inner side of the circle of expansion plates 302; the sides of the two circles of fine-tuning protrusions 3021 are both inclined structures; a rubber sleeve 303 is sleeved on the outer side of the transmission support roller 301; the rubber sleeve 303 is inserted into the outer side of the circle of expansion plates 302; two limiting magnets 304 are fixedly installed on the inner side of the transmission support roller 301, and two The limiting magnets 304 are magnetically connected to the two ends of the expansion plate 302; the limiting magnets 304 are used to limit the ends of the expansion plate 302 in a circle; the correction radius adjustment member 4 includes: a radius adjustment screw 401 and an extrusion column 402, and handles are respectively provided at both ends of the radius adjustment screw 401; the radius adjustment screw 401 is threadedly connected to the transmission support roller 301; an extrusion column 402 is fixedly installed in the middle of the radius adjustment screw 401, and the two sides of the extrusion column 402 are inclined structures; the inclined surfaces on both sides of the extrusion column 402 are respectively pressed and fitted with the fine-tuning protrusions 3021; ​​the extrusion column 402 is used to squeeze and fine-tune the expansion plate 302 in a circle, and the correction radius adjustment member 4 is used in conjunction with the transmission support member 3 to drive the expansion plate 302 in a circle. The end expands outward to form an inclination to adapt to the deformation of the belt, ensure that the tensioning pressure of the belt is consistent during operation, and reduce its deviation. The expandable expansion plate 302 used in this structure can cooperate with the rubber sleeve 303 to ensure stable transportation, and the rubber sleeve 303 can be used to increase the fit with the belt. A circle of expansion plate 302 can expand and adapt the expansion plate 302 on the relatively loose side of the belt according to needs, with high fine-tuning accuracy. At the same time, with the detection of the pressure sensor 202, the adjustment is more flexible and the operation difficulty is low. The adaptation of the deformed belt also helps to increase the service life of the belt. The deformed side of the belt will be relatively loose, that is, the circumference of the two sides of the belt is inconsistent, and the positioning screw is rotated out. When bolt 203 is engaged, roller frame 101 loses its limit position. At this time, the belt on the side with relatively large tension will pull and drive roller frame 101 to rotate. At this time, pressure sensor 202 detects pressure in real time and displays the value through display 105. The extrusion column 402 is driven to move by rotating radius adjustment screw 401.

[0039] Among them, the correction detection part 5 includes: a detection frame 501, an extrusion slider 502 and a micro switch 503. The detection frame 501 is fixedly installed on the roller frame 101 by bolts; the extrusion sliders 502 are slidably installed at both ends of the detection frame 501; the ends of the extrusion sliders 502 are arc-shaped structures; the micro switches 503 are fixedly installed at both ends of the detection frame 501 through brackets; the ends of the micro switches 503 fit the extrusion sliders 502; the two extrusion sliders 502 are used to detect the deviation of the conveyor belt; the threaded correction part 6 includes: a correction swing arm 601, a drive motor 6011, a correction roller 602 and a spiral protrusion 603, and two correction swing arms 601 are rotatably installed on the roller frame 101; the two correction swing arms 601 are respectively fixedly installed with drive motors 6011; the output shafts of the two drive motors 6011 are respectively fixedly installed with correction rollers 602, and the ends of the two correction rollers 602 rotate Fitting; spiral protrusions 603 are fixedly installed on the two deviation correction rollers 602, and the two spiral protrusions 603 are both rubber anti-skid structures; the bottoms of the two deviation correction swing arms 601 are both iron structures; the two electromagnets 106 are used to magnetically attract the two deviation correction swing arms 601; the spiral protrusions 603 are used to fit on the bottom of the conveyor belt; the two micro switches 503 are electrically connected to the two drive motors 6011 respectively, and the deviation correction detection part 5 is adopted to correct the deviation efficiently and directly, and the threaded deviation correction part 6 can be used to prevent damage to the belt edge. The spiral spiral protrusions 603 are used to correct the deviation quickly and will not squeeze the belt edge. During the belt conveying process, the slider 502 is squeezed and touched, and then the micro switch 503 is squeezed. At this time, the micro switch 503 will control the drive motor 6011 in the deviation direction to stop rotating, thereby realizing the deviation correction work, and the spiral structure of the spiral protrusion 603 also plays a cleaning role.

[0040] Embodiment 2, on the basis of embodiment 1, the splicing detection part 7 comprises: a detection installation shell 701 and a lifting column 702, the detection installation shell 701 is fixedly installed on the side of the detection frame 501 by bolts; a lifting column 702 is slidably installed on the detection installation shell 701; the lifting column 702 is used to be squeezed down by the belt connecting buckle; the height of the detection installation shell 701 is lower than the height of the lower edges of the two extrusion sliders 502; the splicing detection part 7 also comprises: an anti-false touch spring 703 and a delay switch 704, the anti-false touch spring 703 is sleeved inside the detection installation shell 701; the anti-false touch spring 703 is located below the lifting column 702; a delay switch 704 is fixedly installed inside the detection installation shell 701, and the end of the delay switch 704 is located below the lifting column 702; the delay switch 704 is electrically connected to two electromagnets 106, and the splicing detection part 7 is used to detect the seams of the belt. Detection, especially for belts connected by buckles or sewed connections, the joints can realize automatic control of the threaded correcting parts 6 to avoid, to avoid the threaded correcting parts 6 from wearing the joints, can increase the service life of the belt, the protection effect is better, and the problem of reduced belt connection strength or even breakage caused by long-term wear of the joints by the correcting wheels during the correction process is prevented. The structure detection is direct, and the bulge at the buckle connection of the non-welded belt is utilized. The control is precise and does not affect the threaded correcting parts 6 in correcting the belt at any other position. During the operation of the belt, when the belt buckle passes through the lifting column 702, the raised buckle will squeeze the lifting column 702 to move down and press the delay switch 704. At this time, the delay switch 704 can control the electromagnet 106 to pass the electromagnetic suction correction swing arm 601. At this time, the correction swing arm 601 will drive the correction roller 602 to press down and no longer fit the belt to avoid damage to the buckle.

[0041] A method for automatic centering of conveyor belts:

[0042] a. When the belt passes through the detection frame 501 and the belt deviates and squeezes and touches the squeezing slider 502, the micro switch 503 is pressed, and the micro switch 503 controls the drive motor 6011 in the direction of the deviation to stop rotating, while the drive motor 6011 in the opposite direction continues to drive the deviation correction roller 602 to drive the spiral protrusion 603 to rotate, and the belt is pulled back by the rubber bolt;

[0043] b. The rotating radius adjustment screw 401 drives the extrusion column 402 to move, extruding the fine-tuning bump 3021 on the corresponding side. After the fine-tuning bump 3021 on the inclined surface is compressed, the extrusion expansion plate 302 rotates, controlling the rubber sleeve 303 to produce an inclined tension belt.

[0044] The working principle of this embodiment is as follows: the rotating adapter plate 102 is installed on the conveyor frame through the bolts. When the deviation correction belt needs to be adjusted, the positioning bolt 203 is rotated and unscrewed, and the roller frame 101 loses its limit. At this time, the belt on the side with relatively large tension will pull and drive the roller frame 101 to rotate. At this time, the pressure sensor 202 detects the pressure in real time and displays the value through the display 105. Once the value deviation of the two displays 105 is large, the extrusion column 402 can be driven to move by rotating the radius adjustment screw 401 to fine-tune the pressure value to the side with smaller pressure value. The protrusion 3021 moves and squeezes the fine-tuning protrusion 3021 on the corresponding side. After the fine-tuning protrusion 3021 on the inclined surface is compressed, it drives the expansion plate 302 to separate from the limiting magnet 304 on the corresponding side, and the limiting magnet 304 on the other side plays a limiting role. At this time, one end of the expansion plate 302 is squeezed out, and the rubber sleeve 303 can be controlled to have an inclination in a "truncated cone" shape. At this time, the belt on the relatively loose side will be tightened, and the corresponding roller frame 101 will also be restored to be aligned with the deformation detection mounting plate 201, and the values ​​displayed on the two displays 105 will also be closer, which can be based on The belt passes through the detection frame 501. During the belt conveying process, if the belt deviates, it will squeeze the contact and squeeze slider 502, and then squeeze the micro switch 503. At this time, the micro switch 503 will control the drive motor 6011 in the direction of the deviation to stop rotating, while the opposite drive motor 6011 continues to drive the deviation correction roller 602 to drive the spiral protrusion 603 to rotate, and the rubber bolt is used to pull back the belt to achieve deviation correction. During the operation of the belt, when the belt buckle passes the lifting column 702, the protruding buckle will squeeze the lifting column 702. After moving downward and compressing the anti-accidental touch spring 703, press the delay switch 704. At this time, the delay switch 704 can control the electromagnet 106 to pass the electromagnetic suction correction swing arm 601. At this time, the correction swing arm 601 will drive the correction roller 602 to press down and no longer fit the belt. After the correction roller 602 passes through the joint at the delay switch 704, the electromagnet 106 is powered off, and the fitting spring 104 will elastically squeeze the correction swing arm 601 to control the correction roller 602 to fit the belt. At the same time, under the compression of the anti-accidental touch spring 703, the lifting column 702 will also move up and reset.
