DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 6 , the present invention provides three technical solutions: For example, see Figure 1-Figure 2In an embodiment of the present invention, a belt conveyor with a deviation correction mechanism includes a concave conveying frame 1, two circular grooves 2 are arranged on both sides of the interior of the concave conveying frame 1, and transmission rollers 3 are rotatably arranged between the circular grooves 2 corresponding to each other on both sides of the interior of the concave conveying frame 1, and the two transmission rollers 3 are connected by a conveyor belt 4. One end of the transmission roller 3 is located outside the circular groove 2 and is laterally slidably sleeved with a push block 5, a groove 6 is arranged on the inner side of the concave conveying frame 1 near the transmission roller 3, a guide roller 7 is rotatably arranged in the groove 6, one side of the guide roller 7 extends out of the groove 6, and a deviation correction trigger 8 is arranged on the upper side of the concave conveying frame 1.

[0019] See also Figure 2-Figure 3 In the embodiment of the present invention, the deviation correction trigger 8 includes a driving wheel 81 and a driven wheel 82 rotatably arranged on the upper side of the concave conveyor frame 1, the lower end of the driven wheel 82 is connected to the guide roller 7 through an axis, and a reset component corresponding to the guide roller 7 is arranged at the bottom of the concave conveyor frame 1 for resetting the guide roller 7, the driving wheel 81 and the driven wheel 82 are connected by a belt 83, and a T-shaped eccentric shaft 84 is arranged at the edge of the upper part of the driving wheel 81 away from the conveyor belt 4, and the outer side of the T-shaped eccentric shaft 84 is laterally slidably sleeved with a groove plate 85, and an L-shaped rod 86 is arranged on the side of the groove plate 85 away from the conveyor belt 4, and the other end of the L-shaped rod 86 is vertically connected to a limiting plate 87, and both ends of the limiting plate 87 are horizontally connected to a fixed shaft 88, and the ends of the two fixed shafts 88 away from the limiting plate 87 slide laterally through the outer side of the concave conveyor frame 1 and are arranged in the circular groove 2 and connected with the push block 5.

[0020] In the above scheme: when the conveyor belt 4 deviates, one side of the conveyor belt 4 will approach the guide roller 7. When the conveyor belt 4 contacts the guide roller 7, under the conveyance of the conveyor belt 4, the conveyor belt 4 will drive the guide roller 7 to rotate. At this time, the guide roller 7 drives the volute spring 72 to tighten, and the guide roller 7 will also drive the driven wheel 82 to rotate. The driven wheel 82 causes the belt 83 to drive the driving wheel 81 to rotate. The driving wheel 81 causes the T-shaped eccentric shaft 84 to make an eccentric movement. The T-shaped eccentric shaft 84 will drive the groove plate 85 to move laterally. The groove plate 85 will cause the L-shaped rod 86 to drive the limit plate 87 to move laterally. The fixed shafts 88 at both ends of the limit plate 87 will push the push block 5 to slide on the transmission roller 3, and the push block 5 will push the conveyor belt 4 to move and make it straight. When the conveyor belt 4 is straightened, the conveyor belt 4 will leave the position of the guide roller 7, and the reset component will cause the guide roller 7 to rotate in the opposite direction, thereby causing the push block 5 to move into the circular notch 2, which will not hinder the normal conveying work of the conveyor belt 4.

[0021] For further information, see Figure 2-Figure 3In the embodiment of the present invention, the reset component includes a T-shaped shaft 71 rotatably arranged at the bottom of the concave conveyor frame 1, the upper end of the T-shaped shaft 71 is connected to the lower end of the guide roller 7, and a spiral spring 72 is arranged on the outside of the T-shaped shaft 71, and the two ends of the spiral spring 72 are respectively connected to the inner side of the T-shaped shaft 71 and the bottom of the concave conveyor frame 1. When the conveyor belt 4 is pushed straight, the conveyor belt 4 will leave the position of the guide roller 7 and will be reset under the elasticity of the spiral spring 72. Therefore, the spiral spring 72 will cause the guide roller 7 to rotate in the opposite direction, thereby causing the push block 5 to move into the circular groove 2, without hindering the normal conveying work of the conveyor belt 4.

[0022] For further information, see Figure 2-Figure 3 In the embodiment of the present invention, guide shafts 851 are provided at the lower parts of both ends of the slot plate 85, and strip guide grooves 101 corresponding to the guide shafts 851 are provided at both sides of the upper side of the concave conveying frame 1 located on the driving wheel 81. The lower end of the guide shaft 851 is arranged in the guide groove 101 and is laterally slidably connected to the concave conveying frame 1. When the slot plate 85 moves, the guide shaft 851 will slide in the guide groove 101, thereby guiding the slot plate 85.

[0023] For further information, see Figure 2-Figure 3 In the embodiment of the present invention, when the guide roller 7 stops rotating, the volute spring 72 is in a reset state. When the conveyor belt 4 drives the guide roller 7 to rotate, the guide roller 7 tightens the volute spring 72. When the conveyor belt 4 leaves the guide roller 7, the volute spring 72 will reset, thereby resetting the guide roller 7.

[0024] The second embodiment is different from the first embodiment in that: See also Figure 4 and Figure 5 In the embodiment of the present invention, the belt conveyor with a correction mechanism also includes a tensioning mechanism 9 for automatically tensioning the conveyor belt 4. The tensioning mechanism 9 includes a motor 91 installed at the bottom of the concave conveyor frame 1. The output shaft of the motor 91 is located in the concave conveyor frame 1 and is connected to a screw 92. The outer part of the screw 92 is screwed with a moving seat 93 through a thread. One end of the moving seat 93 is connected to a limiting cylinder 94. A moving shaft 95 is longitudinally slidably arranged in the limiting cylinder 94. The upper end of the moving shaft 95 extends out of the limiting cylinder 94 and is rotatably connected to a pressure wheel 97. The pressure wheel 97 is pressed against the bottom of the conveyor belt 4 to tension it, and the lower end of the moving shaft 95 is connected to the inner side of the limiting cylinder 94 by a compression spring 96. The tensioning mechanism 9 also includes a correction control mechanism 98 for controlling the operation of the motor 91.

[0025] In the above scheme: when the conveyor belt 4 is transporting, the pressure wheel 97 presses the conveyor belt 4 to play a tensioning role. When the conveyor belt 4 loosens and slips, the pressure of the conveyor belt 4 on the pressure wheel 97 becomes smaller. Under the elasticity of the compression spring 96, the compression spring 96 will drive the movable shaft 95 to move upward, and the movable shaft 95 drives the pressure wheel 97 to move upward, thereby continuing to tension the conveyor belt 4.

[0026] Embodiment 3 is different from Embodiment 1 in that: See also Figure 4 and Figure 5 In the embodiment of the present invention, the correction control mechanism 98 includes a limit seat 981 connected to one side of the moving shaft 95, and a limit groove corresponding to the limit seat 981 is provided on one side of the limit cylinder 94. The end of the limit seat 981 away from the moving shaft 95 extends out of the limit groove, and the upper and lower parts of the end of the limit seat 981 away from the moving shaft 95 are connected to buffer springs 982, and the other ends of the two buffer springs 982 are respectively connected to the upper top shaft 983 and the lower top shaft 984, and one side of the limit cylinder 94 is located at the upper and lower parts of the limit seat 981. The upper contact switch 986 and the lower contact switch 987 are respectively provided on the side of the two mounting plates 985 close to the limit seat 981, and the upper contact switch 986 and the lower contact switch 987 correspond to the positions of the upper top shaft 983 and the lower top shaft 984, respectively.

[0027] See also Figure 6 In the embodiment of the present invention, the upper contact switch 986 and the lower contact switch 987 form a double-control switch with the motor 91.

[0028] See also Figure 4 and Figure 5 In the embodiment of the present invention, after the pressure wheel 97 tensions the conveyor belt 4, the compression spring 96 is in a compressed state. At this time, the lower top shaft 984 just contacts the lower contact switch 987, turning off the power of the motor 91. When the compression spring 96 is in a reset state, the upper top shaft 983 contacts the upper contact switch 986, turning on the power of the motor 91.

[0029] In the above scheme: when the conveyor belt 4 is loose, the compression spring 96 drives the pressure wheel 97 to continue to move upward, and the compression spring 96 gradually resets. At this time, the pressure of the pressure wheel 97 on the conveyor belt 4 gradually decreases. In the process of the moving shaft 95 moving upward, the moving shaft 95 will drive the limit seat 981 to move upward, and the upper top shaft 983 will contact the upper contact switch 986, turning on the power of the motor 91, and the motor 91 drives the screw 92 to rotate, and the screw 92 drives the moving seat 93 to move upward, thereby driving the limit cylinder 94 moves up, so that the pressure wheel 97 continues to press the conveyor belt 4. At this time, as the pressure wheel 97 is pressed, under the reaction force of the conveyor belt 4, the conveyor belt 4 will drive the movable shaft 95 to move downward, compress the compression spring 96, and when the movable shaft 95 moves downward, it will drive the limit seat 981 to move downward. When the lower top shaft 984 contacts the lower contact switch 987, the power supply of the motor 91 will be turned off, and the screw 92 will stop rotating. When the conveyor belt 4 slips again, the above steps are repeated to realize automatic tensioning operation.

[0030] Working principle: When the conveyor belt 4 deviates, one side of the conveyor belt 4 will approach the guide roller 7. When the conveyor belt 4 contacts the guide roller 7, the conveyor belt 4 will drive the guide roller 7 to rotate. At this time, the guide roller 7 drives the volute spring 72 to tighten, and the guide roller 7 will also drive the driven wheel 82 to rotate. The driven wheel 82 drives the belt 83 to drive the driving wheel 81 to rotate. The driving wheel 81 makes the T-shaped eccentric shaft 84 do eccentric movement, and the T-shaped eccentric shaft 84 will drive the groove plate 85 to move horizontally. The groove plate 85 will cause the L-shaped rod 86 to drive the limit plate 87 to move horizontally, and the fixed shafts 88 at both ends of the limit plate 87 will push the push block 5 to slide on the transmission roller 3, and the push block 5 will push the conveyor belt 4 to move and make it straight. When the conveyor belt 4 is straightened, the conveyor belt 4 will leave the position of the guide roller 7 and will reset under the elasticity of the volute spring 72. Therefore, the volute spring 72 will make the guide roller 7 rotate in the opposite direction, thereby moving the push block 5 into the circular notch 2, so as not to hinder the normal conveying work of the conveyor belt 4. When the conveyor belt 4 is conveying, the pressure wheel 97 presses the conveyor belt 4 to play a tensioning role. When the conveyor belt 4 is loose and slips, the pressure of the conveyor belt 4 on the pressure wheel 97 becomes smaller. Under the elasticity of the compression spring 96, the compression spring 96 will drive the moving shaft 95 to move upward, and the moving shaft 95 drives the pressure wheel 97 to move upward, and the conveyor belt 4 is continuously tensioned. When the conveyor belt 4 is loose, the compression spring 96 drives the pressure wheel 97 to continue to move upward, and the compression spring 96 gradually returns to its original position. At this time, the pressure of the pressure wheel 97 on the conveyor belt 4 gradually decreases. In the process of the moving shaft 95 moving upward, the moving shaft 95 drives the limit seat 981 to move upward, and the upper top shaft 983 contacts the upper contact switch 986, turning on the power of the motor 91. The motor 91 drives the screw 92 to rotate, and the screw 92 drives the moving seat 93 to move upward, thereby driving the limit cylinder 94 upward. The conveyor belt 4 moves downward, causing the pressure wheel 97 to continue to press the conveyor belt 4. At this time, as the pressure wheel 97 is pressed, the conveyor belt 4 will drive the movable shaft 95 to move downward under the reaction force of the conveyor belt 4, and compress the compression spring 96. When the movable shaft 95 moves downward, it will drive the limit seat 981 to move downward. When the lower top shaft 984 contacts the lower contact switch 987, the power supply of the motor 91 will be turned off, and the screw 92 will stop rotating. When the conveyor belt 4 slips again, the above steps are repeated to realize automatic tensioning operation.
