Description

Technical Field

[0001] This utility model relates to the field of auxiliary wheel technology, and in particular to a guide auxiliary wheel device. Background Technology

[0002] Auxiliary wheels are auxiliary devices that provide additional steering support or correction. When used in processes such as express sorting, transportation, and handling large boxes, auxiliary wheels help express packages be transported and sorted more smoothly, or guide express sorting vehicles and other equipment to run along a specific path.

[0003] Chinese utility model patent CN221472641U discloses a sorting conveyor belt with guiding function, including a device body. The device body includes a first conveyor belt and a sorting table. A positioning detector is provided at the front end of the first conveyor belt. A cylinder is provided in the middle of the first conveyor belt and a movable frame is connected to the inner side of the cylinder. Several guide wheels are rotatably installed inside the movable frame. A scanner is provided at the rear end of the first conveyor belt. The sorting table is located at the rear end of the first conveyor belt and is provided with a hinge seat. A threaded rod is rotatably provided in the middle of the hinge seat and a second conveyor belt is screwed onto the threaded rod.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned equipment, the sorting operation of express delivery is achieved by setting a second conveyor belt, a motor, and a threaded rod. However, when the second conveyor belt transports the boxes, the boxes are prone to deviation in their movement trajectory at horizontal turns, which can cause the boxes to tip over and reduce the efficiency of sorting the boxes. Utility Model Content

[0005] To solve the above problems, this utility model provides a guide auxiliary wheel device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide auxiliary wheel device, including a mounting frame, a conveyor belt is provided between the frame bodies on both sides of the mounting frame, two support frames are provided on the side wall of the mounting frame, and an inclined component for assisting the box to turn is provided between the frame bodies on both sides of the support frame. The inclined component is provided in multiple sets, and each set of the inclined component includes an L-shaped lifting plate provided between the frame bodies on both sides of the support frame, a placement plate fixed between the two L-shaped lifting plates, a U-shaped plate provided on the top of the placement plate, and a guide wheel rotatably installed between the U-shaped plates. A base is provided between the frame bodies on both sides of the support frame, and a lifting mechanism for lifting the guide wheel is provided on the base.

[0007] By adopting the above technical solution, when workers need to limit the movement of boxes during turns, the lifting mechanism first drives the L-shaped lifting plate upwards. The L-shaped lifting plate then moves the U-shaped plate, which in turn moves the guide wheels. When the guide wheels are above the top of the conveyor belt, the workers place the boxes on the conveyor belt. The conveyor belt then transports the boxes to the top of the guide wheels, where the boxes are turned by contact between the guide wheels and the guide wheels. This application changes the traditional method of sorting boxes using a second conveyor belt, improving sorting efficiency and reducing the probability of boxes tipping over when turning horizontally.

[0008] Furthermore, the lifting mechanism includes a transmission assembly, which is provided in two sets and symmetrically distributed. Each set of the transmission assembly includes a fixing block fixed to the bottom of the L-shaped lifting plate, a lifting rod hinged to the fixing block, an upper locking block fixed to the bottom of the L-shaped lifting plate, a sliding rod slidably disposed on the upper locking block, and a limiting block fixed to the top of the base. The end of the sliding rod away from the upper locking block is hinged to the limiting block. A connecting rod is fixed between the two lifting rods. The lifting mechanism also includes a pushing assembly for pushing the connecting rod to slide.

[0009] By adopting the above technical solution, the staff pushes the component to slide the connecting rod, which in turn moves the lifting rod and the sliding rod. The lifting rod and the sliding rod then push the L-shaped lifting plate to rise, and the L-shaped lifting plate moves the guide wheel upward. When the wheel surface of the guide wheel is higher than the top of the conveyor belt, the height of the guide wheel can be adjusted.

[0010] Furthermore, the pushing assembly includes two lower locking blocks fixed to the top of the base, each lower locking block having a through hole for the connecting rod to slide through. The top of the base has two positioning blocks. The pushing assembly also includes a screw rotatably mounted between the two positioning blocks, a movable block sleeved on the screw and threadedly connected to it, and a pushing motor fixed to the side wall of the positioning block and driving the screw to rotate. The screw passes through the positioning block near the pushing motor and is fixed to the output end of the pushing motor. The connecting rod passes through the movable block.

[0011] By adopting the above technical solution, the staff controls the drive motor, which starts the motor and drives the screw to rotate. Since the moving block is threadedly connected to the screw and the connecting rod slides in the slotted hole, the moving block slides along the axis of the screw. The moving block drives the connecting rod to slide, thereby causing the connecting rod to lift the L-shaped lifting plate. The L-shaped lifting plate eventually drives the guide wheel to move upward.

[0012] Furthermore, the L-shaped lifting plate is provided with a drive mechanism for driving the guide wheel to turn. The drive mechanism includes a connecting assembly, which includes a rotating rod rotatably mounted on the top of the placement plate and a gear fixedly sleeved on the rotating rod. The top of the gear is fixedly connected to the bottom of the U-shaped plate. The connecting assembly also includes a rack slidably disposed between the two L-shaped lifting plates and meshing with the gear, a connecting block fixed to the bottom of the rack, and a sliding block fixed to the bottom of the connecting block. The L-shaped lifting plate is provided with a through hole for the rack to pass through. The drive mechanism also includes a drive component for driving the sliding block to move.

[0013] By adopting the above technical solution, the operator drives the sliding block to move through the drive component. The sliding block drives the connecting block fixed to it and the rack fixed to the connecting block to move. Since the gear and the rack mesh, the rack drives the gear to rotate. The gear drives the U-shaped plate fixed to it and the guide wheel connected to the U-shaped plate to rotate. The operator can then adjust the angle of the guide wheel according to the needs of the site.

[0014] Furthermore, the drive assembly includes a lead screw rotatably mounted between the two L-shaped lifting plates and threadedly connected to the sliding block, a limiting rod fixed between the two L-shaped lifting plates, and a drive motor fixed to the side wall of the L-shaped lifting plate and driving the lead screw to rotate. The limiting rod passes through the sliding block and slides with the sliding block. The lead screw passes through the L-shaped lifting plate near the drive motor and is fixed to the output end of the drive motor.

[0015] By adopting the above technical solution, the staff controls the drive motor, which starts and drives the lead screw to rotate. Since the sliding block is threadedly connected to the lead screw and the limit rod passes through the sliding block, the sliding block slides along the axis of the lead screw, and the sliding block eventually drives the guide wheel to turn.

[0016] Furthermore, a first bellows sleeved on the outside of the lead screw is fixed between the sliding block and the L-shaped lifting plate.

[0017] By adopting the above technical solution, the first bellows prevents dust and other debris from falling onto the lead screw, thus ensuring the stability of the transmission.

[0018] Furthermore, a second bellows sleeved on the outside of the screw is fixed between the two positioning blocks.

[0019] By adopting the above technical solution, the second bellows prevents dust and other debris from falling onto the screw, thus ensuring the stability of the transmission.

[0020] Furthermore, multiple drive rollers are rotatably mounted between the two support frames, and the drive rollers and guide wheels are distributed in an array at intervals.

[0021] By adopting the above technical solution, the setting of the transmission roller enhances the conveying power of the box when turning horizontally, and improves the efficiency of box sorting.

[0022] By adopting the above technical solution, a housing for limiting the rack is fixed on the side wall of the L-shaped lifting plate.

[0023] The further design of the housing serves to limit the rack, preventing it from disengaging from the perforation and ensuring the stability of the transmission. In summary, this utility model has the following beneficial effects: When the operator needs to limit the movement of the box when it is turning, the L-shaped lifting plate is first driven upward by the lifting mechanism. The L-shaped lifting plate drives the U-shaped plate to move, and the U-shaped plate drives the guide wheel to move. When the wheel surface of the guide wheel moves to a position higher than the top of the conveyor belt, the operator places the box on the conveyor belt. The conveyor belt transports the box to the top of the guide wheel. The box can be turned by the wheel surface of the guide wheel contacting the box. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4 As shown in the illustration, this application discloses a guide auxiliary wheel device, including a mounting frame 1, a conveyor belt 11, a support frame 2, a tilting component 3, and a drive mechanism 4. The conveyor belt 11 is disposed between the two sides of the mounting frame 1. The support frame 2 is disposed on the side wall of the mounting frame 1, and two support frames 2 are provided and symmetrically distributed. The tilting component 3 is disposed on the support frame 2 and is used to assist in the turning of the box. Multiple sets of the tilting component 3 are provided, and each tilting component 3 includes an L-shaped lifting plate 35, a placement plate 31, a U-shaped plate 32, and guide wheels 33. The L-shaped lifting plate 35 is disposed between the two sides of the support frame 2, and the cross-section of the L-shaped lifting plate 35 is L-shaped. The placement plate 31 is fixed between the two L-shaped lifting plates 35, the U-shaped plate 32 is disposed on the top of the placement plate 31, and the guide wheels 33 are rotatably mounted between the plates on both sides of the U-shaped plate 32. In this embodiment, a base 12 is provided between the two sides of the support frame 2.

[0028] A lifting mechanism 7 is mounted on the base 12 and is used to lift the L-shaped lifting plate 35. The lifting mechanism 7 includes a transmission assembly 71 and a pushing assembly 72. Two sets of transmission assemblies 71 are symmetrically distributed. Each transmission assembly 71 includes a fixing block 711, a lifting rod 712, an upper locking block 713, a sliding rod 714, and a limiting block 715. The fixing block 711 is fixed to the bottom of the L-shaped lifting plate 35, and the lifting rod 712 is hinged to the fixing block 711. The upper locking block 713 is fixed to the bottom of the L-shaped lifting plate 35, and the sliding rod 714 is slidably mounted on the upper locking block 713. The limiting block 715 is fixed to the top of the base 12, and the end of the sliding rod 714 away from the upper locking block 713 is hinged to the limiting block 715. In this embodiment, a connecting rod 8 is fixed between the two lifting rods 712.

[0029] The pushing assembly 72 is used to push the connecting rod 8 to slide. The pushing assembly 72 includes a lower locking block 721, a screw 722, a moving block 723, and a pushing motor 724. The lower locking block 721 is fixed to the top of the base 12, and two lower locking blocks 721 are provided and symmetrically distributed. Each of the two lower locking blocks 721 has a through hole 7211 for the connecting rod 8 to slide. The top of the base 12 is provided with two positioning blocks 13. The screw 722 is rotatably mounted between the two positioning blocks 13, and the moving block 723 is slidably sleeved on the screw 722 and threadedly connected to it. The pushing motor 724 is fixed to the side wall of the positioning block 13 and drives the screw 722 to rotate. The screw 722 passes through the positioning block 13 near the pushing motor 724 and is fixed to the output end of the pushing motor 724. The connecting rod 8 passes through the moving block 723.

[0030] When the operator needs to limit the movement of the box during a turn, the operator controls the drive motor 724. The drive motor 724 starts and drives the screw 722 to rotate. Since the moving block 723 is threadedly connected to the screw 722 and the connecting rod 8 slides in the through hole 7211, the moving block 723 slides along the axis of the screw 722. The moving block 723 drives the connecting rod 8 to slide, and the connecting rod 8 drives the lifting rod 712 and the sliding rod 714 to move. The lifting rod 712 and the sliding rod 714 push the L-shaped lifting plate 35 to rise. The L-shaped lifting plate 35 drives the guide wheel 33 to move upward. When the wheel surface of the guide wheel 33 moves higher than the top of the conveyor belt 11, the operator places the box on the conveyor belt 11. The conveyor belt 11 transports the box to the top of the guide wheel 33. The box can be turned by the contact between the wheel surface of the guide wheel 33 and the box.

[0031] In this embodiment, a drive mechanism 4 is provided on the L-shaped lifting plate 35. The drive mechanism 4 is used to drive the guide wheel 33 to turn, and the drive mechanism 4 includes a connecting component 41 and a drive component 42. The connecting component 41 includes a rotating rod 411, a gear 412, a rack 413, a connecting block 414, and a sliding block 415. The rotating rod 411 is rotatably mounted on the top of the placement plate 31, and the gear 412 is fixedly sleeved on the rotating rod 411. In this embodiment, the top of the gear 412 is fixedly connected to the bottom of the U-shaped plate 32. The rack 413 is slidably disposed between the two L-shaped lifting plates 35 and meshes with the gear 412. The connecting block 414 is fixed to the bottom of the rack 413. The sliding block 415 is fixed to the bottom of the connecting block 414. A through hole 351 is provided through the L-shaped lifting plate 35 for the rack 413 to pass through.

[0032] The drive assembly 42 is used to drive the sliding block 415 to move. The drive assembly 42 includes a lead screw 421, a limiting rod 422, and a drive motor 423. The lead screw 421 is rotatably mounted between two L-shaped lifting plates 35 and is threadedly connected to the sliding block 415. The limiting rod 422 is fixed between the two L-shaped lifting plates 35, and the drive motor 423 is fixed to the side wall of the L-shaped lifting plate 35 and drives the lead screw 421 to rotate. In this embodiment, the limiting rod 422 passes through the sliding block 415 and slides in cooperation with the sliding block 415, and the lead screw 421 passes through the L-shaped lifting plate 35 near the drive motor 423 and is fixed to the output end of the drive motor 423.

[0033] The operator controls the drive motor 423, which starts and drives the lead screw 421 to rotate. Since the sliding block 415 is threadedly connected to the lead screw 421 and the limiting rod 422 passes through the sliding block 415, the sliding block 415 slides along the axis of the lead screw 421. The sliding block 415 drives the connecting block 414 and the rack 413 fixed to the connecting block 414 to move. Since the gear 412 meshes with the rack 413, the rack 413 drives the gear 412 to rotate. The gear 412 drives the U-shaped plate 32 fixed to it and the guide wheel 33 connected to the U-shaped plate 32 to rotate. The operator can then adjust the angle of the guide wheel 33 according to the needs of the site, thereby guiding the turning box.

[0034] In this embodiment, a first bellows 5 is fixed between the sliding block 415 and the L-shaped lifting plate 35, and is sleeved on the outside of the lead screw 421. The first bellows 5 prevents dust and other debris from falling onto the lead screw 421, thus ensuring the stability of the transmission.

[0035] In this embodiment, a second bellows 9, sleeved on the outside of the screw 722, is fixed between the two positioning blocks 13. The second bellows 9 prevents dust and other debris from falling onto the screw 722, ensuring the stability of the transmission.

[0036] In this embodiment, a drive roller 14 is rotatably mounted between two support frames 2. Multiple drive rollers 14 are provided, and they are arranged in an array with guide wheels 33 at intervals. The gap between two drive rollers 14 is larger than the diameter of the guide wheel 33, ensuring sufficient space for the guide wheel 33 during lifting or lowering. Simultaneously, the drive rollers 14 enhance the conveying power of the box during horizontal turns, improving the efficiency of box sorting.

[0037] In this embodiment, a housing 6 is fixed to the side wall of the L-shaped lifting plate 35. The housing 6 is used to limit the rack 413. The housing 6 limits the rack 413, preventing it from disengaging from the through hole 351 and ensuring the stability of the transmission.
