Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically, to a modular, dockable belt conveyor. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are indispensable and economical logistics transportation equipment for forming rhythmic assembly lines. Belt conveyors can be classified according to their conveying capacity into heavy-duty belt conveyors, such as those used in mining, and light-duty belt conveyors, such as those used in the electronics, plastics, food, light industry, chemical, and pharmaceutical industries. Belt conveyors feature high conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. They utilize the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100 kg or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can convey materials uphill and downhill.

[0003] Existing belt conveyors are typically fixed installations with a fixed height at the discharge end. Therefore, different equipment requires different belt conveyors for its inlet, increasing costs. Furthermore, when the angle between the discharge and inlet sides of an existing belt conveyor is large (or the conveyor's installation angle), if the workpiece has a large surface area, a portion of its surface will be outside the discharge side, reducing the contact area with the conveyor and thus decreasing friction. This can cause slippage at the discharge side, preventing the workpiece from smoothly exiting the conveyor. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a modular dockable belt conveyor. The technical problem to be solved by the present invention is that the discharge side of the belt conveyor in the prior art has a fixed height from the ground, which makes it unable to adapt to different equipment. In addition, when the discharge side angle of the belt conveyor is large, when the workpiece is conveyed on the surface of the belt conveyor, the contact area with the surface of the belt conveyor is reduced, which may cause slippage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular, dockable belt conveyor device, including a base frame, and further comprising:

[0006] A main frame is hinged to one end of the base frame, and the main frame has a drive roller and a first guide roller rotatably connected to both ends of its length from bottom to top;

[0007] A secondary frame is hinged to the upper end of the main frame along its length, and the pivot point of the secondary frame on the main frame is coaxial with the first guide roller.

[0008] A driven roller is rotatably connected to the end of the auxiliary frame away from the first guide roller. Two conveyor belts are mounted together on the driving roller, the first guide roller, and the driven roller, with a gap between the two conveyor belts.

[0009] The support rods are hinged at both ends of the subframe and the base frame, respectively, along the length direction;

[0010] A rotation drive unit for driving the main frame to rotate along the hinge point with the base frame;

[0011] A fixed bracket is fixedly attached to the main frame and located below the main frame. A rotating shaft is horizontally rotatably connected to the fixed bracket. A drive arm is fixedly connected to the rotating shaft. The drive arm can freely pass through the gap between the two conveyor belts.

[0012] A swing drive unit for driving the rotating shaft to swing back and forth.

[0013] Preferably, the main frame is rotatably connected to a second guide roller for tensioning the conveyor belt, the second guide roller corresponding to the first guide roller.

[0014] Preferably, the length of the support rod is the same as the length of the main frame, and the support rod is parallel to the main frame, so that the main frame, the support rod and the base frame form a parallel four-bar linkage.

[0015] Preferably, the rotation drive unit includes:

[0016] A movable hinge seat hinged to the base frame;

[0017] A hydraulic rod is installed on the movable hinge seat, and a movable block is driven and connected to the hydraulic rod. The movable block is hinged to the main frame.

[0018] Preferably, a telescopic rod is provided on the drive arm, the telescopic rod can slide freely on the drive arm, and a telescopic unit is provided on the drive arm. The telescopic unit is used to drive the telescopic rod to move upward and pass through the drive arm when the drive arm rotates upward.

[0019] Preferably, the telescopic unit includes:

[0020] A limiting ring is fixedly fitted onto the telescopic rod, and a sliding cavity is provided inside the drive arm for the limiting ring to engage and for free sliding.

[0021] A spring is wound around the telescopic rod, and the spring elastically abuts against the limiting ring facing downward;

[0022] The fixing block is fixed to the fixing bracket. The longitudinal section of the fixing block is trapezoidal. The lower end of the telescopic rod slides in contact with the waist and top of the fixing block.

[0023] Preferably, the lower end of the telescopic rod is rotatably connected to a roller, and the roller is rotatably connected to the waist and top of the fixed block.

[0024] Preferably, the swing drive unit includes:

[0025] A gear fitted onto one end of the rotating shaft;

[0026] Two lugs are fixed to the side wall of the fixed bracket, and a sliding rod is passed through both lugs, which can slide freely on the lugs.

[0027] A rack portion is provided on the sliding rod, and the rack portion meshes externally with the gear;

[0028] A moving drive component for driving the sliding rod to reciprocate as the active roller rotates.

[0029] Preferably, the moving drive includes:

[0030] A swing arm fixedly mounted on the end of the drive roller;

[0031] A pull rod is rotatably connected to the end of the swing arm away from the drive roller, and the end of the pull rod away from the swing arm is hinged to the sliding rod.

[0032] Preferably, the drive roller is driven to rotate by a servo motor mounted on the main frame.

[0033] The technical effects and advantages of this invention are as follows:

[0034] The main frame is driven to rotate along the pivot point with the base frame by the rotation drive unit, so that the height of the discharge side of the main frame can be adjusted to adapt to different equipment. In addition, by rotating the drive arm, when the workpiece approaches the discharge side of the conveyor belt, the drive arm will rotate upward and push the workpiece upward, so that the workpiece is supported and can be smoothly transported to the conveyor belt at the auxiliary frame, thus realizing the smooth discharge of the workpiece.

[0035] When the drive arm rotates, the telescopic rod moves upward, allowing it to pass through the drive arm. This effectively extends the length of the drive arm, enabling better upward conveying of the workpiece. Additionally, since the telescopic rod can also be placed inside the drive arm, it will not interfere with the workpiece being conveyed later when the drive arm swings downward.

[0036] The rotation of the drive roller causes the swing arm to move the pull rod. When the pull rod moves, it drives the sliding rod to move, which in turn causes the rack on the sliding rod to mesh with the gear and rotate, thereby driving the rotating shaft to rotate back and forth. This allows the drive arm to swing back and forth. The structure is simple and makes the running speed of the conveyor belt match the rotation of the drive arm. Attached Figure Description

Implementation

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1-7 As shown, the present invention provides a modular dockable belt conveyor device, including a base frame 2, a main frame 5 hinged to one end of the base frame 2 along its length, a drive roller 24 and a first guide roller 21 rotatably connected to both ends of the main frame 5 along its length from bottom to top, a servo motor 1 mounted on the main frame 5, the output shaft of the servo motor 1 being drivenly connected to one end of the drive roller 24 via a coupling, thereby enabling the drive roller 24 to rotate when the output shaft of the servo motor 1 rotates, and a secondary frame 8 hinged to the upper end of the main frame 5 along its length, the rotation fulcrum of the secondary frame 8 on the main frame 5 being coaxial with the first guide roller 21, and the secondary frame 8 being located away from the first guide roller 21. A driven roller 20 is rotatably connected to one end of the main frame 5. Two conveyor belts 9 are mounted on the driven roller 24, the first guide roller 21, and the driven roller 20. The two conveyor belts 9 are modular. A second guide roller 22 for tensioning the conveyor belts 9 is also rotatably connected to the main frame 5. The second guide roller 22 corresponds to the first guide roller 21, so that the conveyor belts 9 are tensioned by the squeezing force of the first guide roller 21 and the second guide roller 22. There is a gap between the two conveyor belts 9. When the output shaft of the servo motor 1 rotates, it drives the driven roller 24 to rotate. The rotation of the driven roller 24 drives the two conveyor belts 9, and simultaneously drives the driven roller 20 and the first guide roller 21. 1. Rotation. Additionally, a support rod 7 is hinged to the base frame 2. The end of the support rod 7 furthest from the base frame 2 is hinged to the sub-frame 8, so that both ends of the support rod 7 are hinged to the sub-frame 8 and the base frame 2 respectively along its length. Furthermore, the length of the support rod 7 is the same as the length of the main frame 5, and the support rod 7 is parallel to the main frame 5. This forms a parallel four-bar linkage between the main frame 5, the support rod 7, and the base frame 2. Thus, when the support rod 7 rotates along its hinge point with the base frame 2, it drives the sub-frame 8 to move longitudinally and laterally. During this movement, the length of the sub-frame 8 remains parallel to the base frame 2. The support rod 7 is hinged to the base frame 2. The movable hinge 3 is connected to a hydraulic rod 4 by screws. A threaded sleeve 19 is connected to the hydraulic rod 4, and a movable block 10 is welded to the threaded sleeve 19, thereby driving the hydraulic rod 4 and the movable block 10 to connect. In addition, the movable block 10 is hinged to the main frame 5. By activating the hydraulic rod 4, the output shaft of the hydraulic rod 4 extends, and the output shaft will correspondingly drive the movable block 10 to move up and down, thereby driving the main frame 5 to rotate along the hinge point with the base frame 2. This allows the height of the auxiliary frame 8 off the ground to be adjusted, so that the height of the auxiliary frame 8 off the ground is consistent with the height of the feeding point of the equipment, thus adapting to different equipment and achieving docking and matching with different equipment.

[0047] A fixed bracket 6 is welded to the main frame 5, located below the main frame 5. The fixed bracket 6 has a U-shaped outline, and its two sides are welded to the main frame 5. A rotating shaft 14 is horizontally connected to the fixed bracket 6 via bearings. A drive arm 12 is vertically welded to the rotating shaft 14. The drive arm 12 can freely pass through the gap between the two conveyor belts 9. Furthermore, the gap size between the two conveyor belts 9 matches the outer dimensions of the drive arm 12. A gear 15 is fixedly sleeved at one end of the rotating shaft 14. Two lugs are welded to the side wall of the fixed bracket 6, and a sliding rod 18 is threaded through both lugs. The sliding rod 18 can slide freely on the lugs. Specifically, the lugs... The block has a through hole for the sliding rod 18 to pass through freely, and the through hole and the sliding rod 18 form a sliding fit. The sliding rod 18 has a rack portion 23, which meshes with the gear 15. When the sliding rod 18 moves, the rack portion 23 will mesh with the gear 15 and rotate, thereby driving the rotating shaft 24 to rotate. A swing arm 16 is fixedly sleeved at the end of the drive roller 24. The end of the swing arm 16 away from the drive roller 24 is rotatably connected to a pull rod 17. The end of the pull rod 17 away from the swing arm 16 is hinged to the sliding rod 18. When the main frame 5 is tilted at a large angle, the workpiece is conveyed from bottom to top on the surface of the conveyor belt 9. Driven by the friction between the bottom surface of the workpiece and the surface of the conveyor belt 9, the magnitude of the friction is related to the contact area between the workpiece and the surface of the conveyor belt 9. Therefore, when the workpiece is conveyed upwards, when part of the workpiece surface moves to the outside of the discharge side of the conveyor belt 9, a portion of the bottom surface of the workpiece is not in contact with the conveyor belt 9, resulting in a reduction in the contact area between the workpiece and the surface of the conveyor belt 9, thus reducing the friction. This may cause the workpiece to slip on the discharge side surface of the conveyor belt 9. Therefore, in this embodiment, the rotation of the drive roller 24 drives the swing arm 16 to rotate. The rotation of the swing arm 16 drives the pull rod 17 to move, and the movement of the pull rod 17... When in motion, the sliding rod 18 will slide, causing the rack 23 to mesh and rotate with the gear 15. When the gear 15 rotates, it will drive the rotating shaft 24 to rotate, which will then drive the drive arm 12 to swing from bottom to top. This allows the drive arm 12 to pass through the gap between the two conveyor belts 9 and push the workpiece with the end of the drive arm 12 above the conveyor belt 9. When the workpiece is conveyed upwards, it is supported and propelled by the drive arm 12, thus preventing the workpiece from slipping on the discharge side of the conveyor belt 9. This allows the workpiece to be smoothly conveyed from the conveyor belt 9 on the main frame 5 to the conveyor belt 9 on the auxiliary frame 8, enabling the workpiece to be discharged smoothly.

[0048] Furthermore, since the length of the drive arm 12 is fixed, it may swing in the opposite direction after the previous workpiece is discharged. This could cause the end of the drive arm 12 that extends above the conveyor belt 9 to interfere with the workpiece being conveyed later. Therefore, in this embodiment, the length of the drive arm 12 is set to be less than the distance between the rotation fulcrum of the drive arm 12 on the fixed bracket 6 and the conveyor belt 9, so that the drive arm 12 will not extend above the conveyor belt 9 during its swing. In addition, a telescopic rod 11 is installed on the drive arm 12 for telescopic extension. The telescopic rod 11 can slide freely on the drive arm 12. One end of the telescopic rod 11, which passes through the drive arm 12, is fixedly sleeved with a limit ring 28. The drive arm 12 has a sliding cavity 26 that allows the limit ring 28 to engage and slide freely. A spring 25 is wound around the telescopic rod 11, and the spring 25 elastically abuts the limit ring 28 downwards. A fixing block 13 is welded onto the fixed bracket 6. The longitudinal section of the fixing block 13 is trapezoidal, and the two waist parts of the fixing block 13 correspond to the two sides of the main frame 5 along its length. A roller is rotatably connected to the lower end of the telescopic rod 11. 27. Roller 27 is tactilely connected to the waist and top of fixed block 13. When roller 27 rolls from the waist to the top of fixed block 13, it drives roller 27 to move upward, simultaneously driving telescopic rod 11 to move upward and pass through drive arm 12, so that one end of telescopic rod 11 passing through drive arm 12 can extend above conveyor belt 9. This ensures that the end of telescopic rod 11 passing through conveyor belt 9 can move the workpiece, and when drive arm 12 swings from top to bottom, roller 27 will move from the top of fixed block 13. When the workpiece rolls to the waist of the fixed block 13, the elastic resistance of the spring 25 against the limiting ring 28 causes the telescopic rod 11 to move downward and retract into the drive arm 12. This ensures that after the drive arm 12 moves the previous workpiece toward the discharge side of the conveyor belt 9, it will not interfere with the workpieces being conveyed later on the conveyor belt 9. In addition, in this embodiment, the workpieces are placed on the conveyor belt 9 by workers at certain intervals, which allows the drive arm 12 to intermittently move the workpieces on the conveyor belt 9.

[0049] The working principle of this invention is as follows: When adjusting the height of the discharge side of the conveyor belt 9, the hydraulic rod 4 is activated, the output shaft of the hydraulic rod 4 extends, and the output shaft will drive the movable block 10 to move up and down accordingly. This will drive the main frame 5 to rotate along the hinge with the base frame 2, so that the height of the auxiliary frame 8 off the ground can be adjusted, so that the height of the auxiliary frame 8 off the ground is consistent with the height of the feeding point of the equipment, thus adapting to different equipment and realizing docking and matching with different equipment.

[0050] When servo motor 1 is started, its output shaft rotates, driving the drive roller 24 to rotate. The rotation of drive roller 24 drives the two conveyor belts 9, and simultaneously drives the driven roller 20 and the first guide roller 21 to rotate, thus enabling the conveyor belts 9 to run. Workers place workpieces on the conveyor belts 9 at certain intervals, and the conveyor belts 9 transport the workpieces. During transport, drive roller 24 rotates, causing swing arm 16 to rotate. Swing arm 16 rotates, causing pull rod 17 to move. When pull rod 17 moves, it causes sliding rod 18 to slide, causing rack 23 to mesh with gear 15 and rotate. When gear 15 rotates, it causes rotating shaft 24 to rotate, causing drive arm 12 to swing upwards. This causes roller 27 to roll from the waist of fixed block 13 to the top of fixed block 13, thereby driving telescopic rod 11 to slide upwards, allowing telescopic rod 11 to pass through the drive arm. The telescopic rod 11 extends from the top of the drive arm 12 to the top of the conveyor belt 9, allowing it to move and support the workpiece. As the drive arm 12 swings, the workpiece is smoothly moved to the discharge side of the conveyor belt 9, allowing it to be transported from the main frame 5 to the auxiliary frame 8. Then, as the swing arm 16 continues to rotate, the sliding rod 18 moves in the opposite direction, causing the rack 23 to mesh with the gear 15 in the opposite direction. This causes the drive arm 12 to swing from top to bottom, and the roller 27 to roll from the top of the fixed block 13 to the waist of the fixed block 13. At this time, the spring 25 elastically abuts against the limiting ring 28, causing the telescopic rod 11 to move downward and retract into the drive arm 12. This ensures that after the drive arm 12 moves the previous workpiece to the discharge side of the conveyor belt 9, it will not interfere with the workpieces being transported on the conveyor belt 9 after swinging in the opposite direction.
