Description

Technical Field

[0001] The present invention belongs to the technical field of lightweight material conveying equipment, and specifically relates to a leveling conveyor for evenly feeding lightweight materials. Background Art

[0002] With the development of industry, in places such as factory workshops, the method of relying on manual labor to convey materials can no longer meet the requirements of rapid production and labor saving. Therefore, most factory workshops have used material conveying devices to assist manual conveying, and the belt-type leveling conveyor is a commonly used long-distance conveying tool.

[0003] In the prior art, when the leveling conveyor conveys lightweight materials, some materials will adhere to the conveyor belt. When the conveyor belt carries the materials and rotates, the materials will fall off during the rotation due to vibration, wind flow, etc., causing the lightweight materials to disperse in the working environment and polluting the working environment; during the conveying process, because lightweight materials are prone to accumulation, when the materials accumulate a lot and then move to a high place, sometimes they will fall due to their weight, and some materials will be carried along during the falling process, resulting in less materials in this section and more materials in the subsequent section. Then, when they are fed into the processing box, the subsequent work of the processing box is extremely unstable and the equipment is more likely to be damaged.

[0004] Therefore, we propose a leveling conveyor for evenly feeding lightweight materials to solve the problems encountered above. Summary of the Invention

DETAILED DESCRIPTION

[0026] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0027] Embodiment 1:

[0028] See also Figure 1 - Figure 5 As shown, a flattening conveyor for uniformly loading light materials comprises a frame 1, a silo 2 is arranged at the upper right end of the frame 1, an installation box 3 is arranged at the left outer wall of the silo 2, a driving mechanism 4 is arranged at the left side of the installation box 3, the driving mechanism 4 comprises a driving roller 407, the driving roller 407 is rotatably installed in the frame 1 through a rotating shaft 406, a conveyor belt 6 is movably installed in the frame 1 through the driving roller 407, the driving mechanism 4 also comprises a servo motor 401, and the servo motor 401 is arranged on the left outer wall of the installation box 3 through a motor seat, a power output end of the servo motor 401 is connected to a motor shaft 402 through a coupling, a rotating sprocket 403 is arranged at the rear end of the motor shaft 402, the rotating sprocket 403 is connected to a driven sprocket 405 through a toothed chain 404, the driven sprocket 405 is arranged on the circumferential surface of the rear end of the rotating shaft 406, and the driven sprocket 405 is located at the rear side of the rotating spur gear 701;

[0029] It should be noted that the conveyor belt 6 is arranged with the right end lower and the left end higher. The inner part of the right bottom end of the conveyor belt 6 is rotatably installed inside the frame 1 through a driven roller to limit and support the right bottom end of the conveyor belt 6. The servo motor 401 drives the motor shaft 402 and the first rotating sprocket 403 to rotate counterclockwise, so that the driving roller 407 also rotates counterclockwise when rotating, and then drives the conveyor belt 6 to rotate counterclockwise, thereby smoothly conveying the light material from the right bottom end to the higher left side.

[0030] A cleaning mechanism 7 is arranged below the left side of the conveyor belt 6. The cleaning mechanism 7 includes a rotating spur gear 701, and the rotating spur gear 701 is arranged on the circumferential surface of the rear end of the rotating shaft 406. A driven spur gear 702 is meshed and connected to the right side of the rotating spur gear 701. A gearbox 703 is arranged at the rear end of the driven spur gear 702, and the gearbox 703 is arranged on the rear outer wall of the frame 1 through a mounting seat. A rotating sprocket 704 is arranged at the output end at the rear side of the gearbox 703. The rotating sprocket 704 is drivingly connected to a driven sprocket 706 through a chain 705. A reciprocating lead screw 707 is arranged at the front end of the driven sprocket 706. A moving block 708 is movably connected to the surface of the reciprocating lead screw 707 through a ball screw. Among them, the reciprocating lead screw 707 is a form of a three-dimensional cam pair, which is manifested as two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. Through the rotation of the lead screw, the side surface of the spiral groove pushes the slider placed in the spiral groove to perform an axial reciprocating motion, thereby realizing the forward and backward reciprocating movement of the moving block 708. A rotating rod 709 is rotatably installed at the upper end of the moving block 708. A fan blade 19 is arranged on the circumferential surface of the rotating rod 709. The arrangement of the fan blade 19 enables the fan blade 19 to rotate when the rotating rod 709 rotates, causing air flow here, and in the process of air flow, part of the light materials are blown off. A cleaning brush 710 is arranged at the upper end of the rotating rod 709. The upper surface of the cleaning brush 710 abuts against the lower surface of the left end of the conveyor belt 6. A butting plate 22 is arranged inside the left side of the frame 1. A butting roller 23 is rotatably installed at the lower end of the butting plate 22. The lower end of the butting roller 23 abuts against the inner bottom wall of the conveyor belt 6, and the cleaning brush 710 is located obliquely below the butting roller 23. The arrangement of the butting plate 22 and the butting roller 23 can butt against the lower part of the belt of the conveyor belt 6, enabling the cleaning brush 710 to contact the outer surface of the conveyor belt 6 more stably, and then more smoothly sweeping off the light materials attached to the conveyor belt 6. A U-shaped fixing plate 14 is arranged at the lower left end of the frame 1. Fixed blocks 15 are arranged on the front and rear sides of the lower surface of the U-shaped fixing plate 14. The front and rear ends of the reciprocating lead screw 707 are respectively rotatably installed inside the two fixed blocks 15. The arrangement of the fixed blocks 15 can limit the reciprocating lead screw 707, enabling the reciprocating lead screw 707 to rotate stably. Baffles 24 are arranged on the surface of the conveyor belt 6, and a plurality of baffles 24 are provided. The arrangement of the baffles 24 can block the materials when the conveyor belt 6 conveys the light materials, avoiding the materials falling by gravity when the materials are transferred to a high place and affecting the conveying effect. The outer ends of the plurality of baffles 24 do not contact the inner bottom wall of the U-shaped fixing plate 14, so that when the conveyor belt 6 drives the baffles 24 to rotate, the outer ends of the baffles 24 will not collide with the U-shaped fixing plate 14;

[0031] It should be noted that when the cleaning brush 710 and the baffle 24 are at the same horizontal plane and the cleaning brush 710 is at the rearmost end of the reciprocating lead screw 707 at this time, the front end of the cleaning brush 710 will not contact the rear end of the baffle 24. Then, when the conveyor belt 6 drives the baffle 24 to rotate, the baffle 24 will not collide with the cleaning brush 710 and the rotating rod 709. The set gearbox 703 can increase the rotation speed of the second rotating sprocket 704, so that when the previous baffle 24 moves to the right side of the cleaning brush 710, the moving block 708 drives the rotating rod 709 and the cleaning brush 710 to quickly move horizontally back and forth. When the cleaning brush 710 moves forward and then backward to the rear side of the baffle 24, the next baffle 24 moves to the left side of the cleaning brush 710. At this time, the baffle 24 continues to move to the right, and at the same time, the cleaning brush 710 continues to move backward to the initial position. After the cleaning brush 710 moves to the initial position, this baffle 24 moves to the right side of the cleaning brush 710. Therefore, when the cleaning brush 710 cleans the surface of the conveyor belt 6, it is carried out in the middle section between the two baffles 24. At the same time, due to the rotation and movement of the cleaning brush 710, the lower surface of the left end of the conveyor belt 6 can be cleaned, and air flow will also be generated. At the same time, because the cleaning brush 710 is made of soft materials such as rubber, during the movement process, a small vibration will also be generated on the conveyor belt 6, making it easier for the light materials attached to the surface of the conveyor belt 6 to be swept, vibrated or blown off, thereby avoiding the occurrence of dropping and pollution of the working environment and waste when the conveyor belt 6 carries the light materials and moves downward.

[0032] A moving groove 16 is provided in the middle of the U-shaped fixing plate 14, and a toothed plate 17 is arranged on the left side of the moving groove 16. A driven spur gear 18 is arranged on the circumferential surface of the rotating rod 709, and the left side of the driven spur gear 18 meshes with the toothed plate 17. The setting of the moving groove 16 provides a moving space for the driven spur gear 18, so that the moving block 708 can smoothly drive the driven spur gear 18 to move horizontally back and forth. Moving grooves 21 are provided on the left and right sides of the lower surface of the U-shaped fixing plate 14. Limit connecting blocks 20 are slidably installed inside the two moving grooves 21. The lower ends of the two limit connecting blocks 20 are respectively fixedly connected to the left and right sides of the upper surface of the moving block 708. The setting of the moving groove 21 provides a moving space for the limit connecting blocks 20, so that the limit connecting blocks 20 can smoothly move horizontally back and forth. The setting of the limit connecting blocks 20 can limit the moving block 708, so that when the reciprocating lead screw 707 rotates, the moving block 708 can move horizontally back and forth on the reciprocating lead screw 707;

[0033] The driving sprocket 403, the first toothed chain 404, and the driven sprocket 405 are all located at the rear side of the frame 1. The lower left end of the first toothed chain 404 is located above the input end of the gearbox 703. Both the front and rear ends of the rotating shaft 406 are rotatably connected to the first fixing block 13. The upper ends of the two first fixing blocks 13 are respectively fixedly connected to the front and rear ends of the lower surface of the left side of the frame 1. The setting of the first fixing block 13 can support and fix the rotating shaft 406, so as to rotatably install the rotating shaft 406 and the driving roller 407 inside the frame 1.

[0034] Embodiment 2:

[0035] Please refer to Figure 2 and Figure 4 As shown, an adjusting mechanism 5 is arranged inside the installation box 3. The adjusting mechanism 5 includes a U-shaped lifting plate 501. A screw rod 502 is rotatably installed in the middle of the U-shaped lifting plate 501. The upper end of the screw rod 502 is threadedly connected to the upper inner part of the installation box 3. A roller shaft 505 is rotatably installed inside the lower end of the U-shaped lifting plate 501. A pressure roller 503 is arranged on the circumferential surface in the middle of the roller shaft 505. A belt driven wheel 506 is arranged on the circumferential surface at the rear end of the roller shaft 505. The belt driven wheel 506 is drivingly connected to a belt driving wheel 508 through a transmission belt 507. The belt driving wheel 508 is arranged on the circumferential surface of the motor shaft 402. A limiting mounting plate 25 is arranged at the lower end of the screw rod 502. The upper surface of the limiting mounting plate 25 abuts against the lower surface of the U-shaped lifting plate 501 through a ball.

[0036] It should be noted that by rotating the screw rod 502, the screw rod 502 can move slightly up and down in the installation box 3. And because of the setting of the ball and the limiting mounting plate 25, the screw rod 502 will not drive the U-shaped lifting plate 501 to rotate when rotating. At the same time, when the screw rod 502 moves up and down, it will also drive the U-shaped lifting plate 501 to move up and down. Then the U-shaped lifting plate 501 will synchronously drive the roller shaft 505 and the pressure roller 503 to move up and down. Then, the height of the pressure roller 503 can be adjusted according to different masses of light substances. When encountering lighter materials, the stacking height of the materials can be higher. Therefore, the pressure roller 503 can be adjusted upward by a certain distance, making it more flexible to use.

[0037] Limit lifting plates 504 are provided on both the left and right sides of the U-shaped lifting plate 501. Lifting grooves 9 are formed on the inner walls of both the left and right sides of the installation box 3. One sides of the two limit lifting plates 504 away from the U-shaped lifting plate 501 are respectively arranged inside the two lifting grooves 9. The arrangement of the lifting grooves 9 provides a moving space for the limit lifting plates 504, enabling the limit lifting plates 504 to move up and down smoothly while limiting the U-shaped lifting plate 501. A feed inlet 8 is formed below the left end of the storage bin 2. The pressure roller 503 is arranged on the left side of the feed inlet 8, and the lower end of the pressure roller 503 is located above the top of the baffle 24. The bottom of the pressure roller 503 does not contact the baffle 24, so that during the movement of the baffle 24, it will not collide and damage the pressure roller 503, improving the service life of the equipment;

[0038] A first fixed mounting plate 10 is arranged at the rear end of the left side of the U-shaped lifting plate 501. A connecting rod 26 is arranged at the rear end of the first fixed mounting plate 10. A second fixed mounting plate 11 is arranged on the circumferential surface of the connecting rod 26. Tensioning wheels 12 are rotatably connected to the rear ends of the connecting rod 26 and the rear side of the second fixed mounting plate 11 through rotating support rods. The two tensioning wheels 12 are respectively abutted against the inner walls of the upper and lower sides of the transmission belt 507. The arrangement of the two groups of tensioning wheels 12 can keep the tension of the transmission belt 507 unchanged after the pressure roller 503 is adjusted up and down. Then, when the motor shaft 402 drives the belt driving wheel 508 to rotate, the belt driving wheel 508 can stably drive the belt driven wheel 506 and the roller shaft 505 to rotate through the transmission belt 507.

[0039] When the present invention is in use, first, the left end part of the conveyor belt 6 is arranged at the upper material inlet of the processing box. Then, granular, powdery and other light materials are conveyed into the storage bin 2. Then, the screw rod 502 is rotated, so that the U-shaped lifting plate 501 drives the pressure roller 503 to move in a direction perpendicular to the conveyor belt 6 with the conveyor belt 6 as the reference plane, thereby adjusting the distance between the bottom of the pressure roller 503 and the baffle 24. When the conveyor belt 6 transfers the light material from the right side of the storage bin 2 to the upper left side, the pressure roller 503 can push the material higher than the bottom of the pressure roller 503 to the right, making the height of the material relatively uniform during transportation, and also avoiding pushing too much material at one time, resulting in some materials sliding to the right due to the weight when the materials are transferred to a higher position, resulting in less material added, and then avoiding too much or too little intermittent feeding, which affects the subsequent work;

[0040] Then, the servo motor 401 is started. The servo motor 401 drives the motor shaft 402 to rotate counterclockwise. The rotation of the motor shaft 402 drives the belt driving wheel 508 to rotate, so that the belt driving wheel 508 drives the belt driven wheel 506, the roller shaft 505 and the pressure roller 503 to rotate counterclockwise through the transmission belt 507. The counterclockwise rotation of the pressure roller 503 can smoothly push the material piled up higher on the conveyor belt 6 to the right, making the material transportation more uniform;

[0041] During the rotation of the motor shaft 402, the first rotating sprocket 403 will also be driven to rotate synchronously. The first rotating sprocket 403 drives the first driven sprocket 405 to rotate through the first tooth chain 404. The rotation of the first driven sprocket 405 drives the rotating shaft 406 and the driving roller 407 to rotate, so that the driving roller 407 drives the conveyor belt 6 to rotate counterclockwise, and then conveys the light materials inside the bin 2 from right to the left high place, and then falls at the leftmost end of the conveyor belt 6 and falls into the interior of the processing box for processing;

[0042] When the rotating shaft 406 rotates, it will also drive the rotating spur gear 701 to rotate. The rotation of the rotating spur gear 701 drives the first driven spur gear 702 to rotate, so that the first driven spur gear 702 drives the second rotating sprocket 704 to rotate through the speed change box 703. The second rotating sprocket 704 drives the second driven sprocket 706 and the reciprocating lead screw 707 to rotate through the second tooth chain 705, so that the moving block 708 on the reciprocating lead screw 707 moves back and forth. When the moving block 708 drives the rotating rod 709 and the cleaning brush 710 to move forward, the second driven spur gear 18 on the rotating rod 709 will mesh with the toothed plate 17 on the U-shaped fixing plate 14, so as to rotate, and then drive the rotating rod 709 and the cleaning brush 710 to rotate, so that while the cleaning brush 710 moves back and forth on the lower surface of the conveyor belt 6, it will also rotate itself, so that the cleaning effect of the cleaning brush 710 on the surface of the conveyor belt 6 is better, and the materials that may adhere to the surface of the conveyor belt 6 are swept down, and then directly fall into the interior of the processing box. At the same time, during the rotation of the rotating rod 709, it will also drive the fan blade 19 to rotate, so that when the rotating rod 709 moves back and forth, air flow is generated inside the U-shaped fixing plate 14, so that some of the light materials falling on the U-shaped fixing plate 14 or the reciprocating lead screw 707 are blown down, and then the materials fall into the interior of the processing box, reducing the loss of materials.

The preferred embodiments do not describe all the details in detail, nor limit the invention to the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made.
