Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to an anti-dumping device for conveying cartons. Background Art

[0002] Cartons, as widely used packaging products, are usually made of multiple layers of corrugated cardboard glued together. They have good load-bearing capacity and pressure resistance. Depending on the materials used, they can be divided into various types such as corrugated boxes and single-layer cardboard boxes. Common ones are three-layer and five-layer structures. The materials of each layer include lining paper, corrugated paper, core paper and face paper. The different combinations of these materials enable cartons to adapt to the packaging needs of various commodities. During the transportation of cartons, due to the complexity of the transportation environment and uncontrollable factors such as sudden braking and turning, cartons may dump or tilt due to inertia, causing damage to the goods or safety hazards. Therefore, the use of anti-dumping devices is particularly important.

[0003] The existing Chinese patent with announcement number CN214927466U discloses a conveying anti-drop device for carton processing, including a conveying mechanism, the outer end of which is transmission-connected to a limiting mechanism, the conveying mechanism including a motor housing, a support frame, a motor, a first transmission gear, a first transmission shaft, a rotating rod, a conveying belt and a cardboard, the support frame is arranged at the inner end of the conveying mechanism, and the rotating rod rotates evenly and is clamped on the upper part of the inner end of the support frame.

[0004] Although the above scheme has completed the anti-dropping measures for carton processing and transportation, when the conveying path introduces a turning link, the fixed structure of the device is not easy to adjust, resulting in poor anti-dumping effect at the turning point. Due to the significant effect of centrifugal force during the turning process, the carton can easily lose its original balance, thereby increasing the risk of dumping and falling. At the same time, the structure of the device is not easy to move, so it does not meet the existing needs. In this regard, we propose an anti-dumping device for carton transportation. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-dumping device for carton conveying, so as to solve the problems that the anti-dumping device proposed in the above background technology has poor anti-dumping effect at turns and is inconvenient for overall movement.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an anti-dumping device for carton conveying, comprising a mobile frame, two fixed plates are provided on the inner side of the mobile frame, and four universal wheels are installed on both sides of the lower end of the mobile frame;

[0007] The machine further comprises a transmission cavity, which is opened at a middle position between the front and rear ends of the fixed plate, and a rotation cavity is opened on the upper sides of the front and rear ends of the fixed plate. A rotating shaft is provided inside the transmission cavity, and both ends of the rotating shaft pass through and extend into the interior of the rotating cavity, and the rotating shaft is rotatably connected to the rotating cavity. A rotating block is provided inside the rotating cavity, and the rotating shaft passes through the rotating block and is fixedly connected to the rotating block.

[0008] It also includes threaded rods, which are rotatably arranged on both sides of the interior of the mobile frame, the exteriors of the threaded rods are threadedly connected to lifting blocks, one end of the lifting blocks extends to the exterior of the mobile frame, and the ends of the lifting blocks located outside the mobile frame are connected to the fixed plate;

[0009] It also includes rotating rods, which are arranged on both sides of the lower side of the front and rear ends of the mobile frame, and the rotating rods are threadedly connected to the mobile frame. Both ends of the rotating rods pass through and extend to the outside of the mobile frame, and the lower ends of the rotating rods are provided with rubber anti-sliding blocks.

[0010] Preferably, a motor is provided below the threaded rod, and the output end of the motor is connected to the threaded rod via a coupling.

[0011] Preferably, guide grooves are provided on the front and rear sides of the threaded rod, and the guide grooves are slidably matched with the lifting blocks.

[0012] Preferably, a transmission worm wheel is provided on the outer wall of the rotating shaft at one end inside the transmission cavity, a transmission worm is rotatably provided on one side inside the transmission cavity, and worm transmission is implemented between the transmission worm and the transmission worm wheel.

[0013] Preferably, one end of the transmission worm extends to the outside of the transmission cavity, and a second knob is installed on the end of the transmission worm located outside the transmission cavity.

[0014] Preferably, a first knob is installed on the upper end of each rotating rod.

[0015] Preferably, adjustment plates are provided at the front and rear sides of the fixed plate, and the adjustment plates are adhered and fixed to one end of the rotating block located outside the rotating cavity.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model provides adjustment plates at the front and rear of the fixed plate. When the operator turns the second knob, the second knob will drive the transmission worm to rotate. The worm transmission between the transmission worm and the transmission worm wheel will cause the rotating shaft to rotate synchronously. The rotating shaft will drive the rotating block in the rotating cavity to rotate the adjustment plate synchronously, thereby changing the angle between the adjustment plate and the fixed plate. By adjusting the angles of the two adjustment plates, different turning points can be adapted to protect the turning points, effectively preventing cartons from falling through the turning points. At the same time, since the worm transmission is self-locking, the adjustment plate can remain stable after adjustment, and the angle will not change due to the collision of the cartons, thereby ensuring the accuracy and reliability of the adjustment.

[0018] 2. The utility model installs universal wheels on both sides of the lower end of the mobile frame. The universal wheels roll on the ground, so that the mobile frame can be easily moved and moved to the conveyor belt. The rotating rod can be rotated synchronously by turning the first knob. The rotating rod will drive the rubber anti-sliding block to contact the ground, which can increase the friction with the ground, thereby effectively preventing the mobile frame from sliding or accidentally moving when it stops, ensuring the safety and stability of the operation.

[0019] 3. The utility model has threaded rods rotatably arranged on both sides of the mobile frame. When the motor is started, the threaded rods can be rotated, and the threaded rods will drive the lifting block to move vertically up and down. The lifting block will drive the fixed plate and the adjustment plate to rise and fall synchronously, so that the height can be adjusted according to the conveyor belts at different heights, which increases the applicability and enables the fixed plate and the adjustment plate to be adjusted to the optimal protection height, further preventing the cartons from falling during transportation.

DETAILED DESCRIPTION

[0025] 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 embodiments described 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.

[0026] See also Figure 1-4 The utility model provides a technical solution: an anti-dumping device for carton conveying, comprising a mobile frame 1, two fixed plates 10 are provided on the inner side of the mobile frame 1, and four universal wheels 2 are installed on both sides of the lower end of the mobile frame 1;

[0027] The fixed plate 10 further includes a transmission cavity 12, which is opened at a middle position between the front and rear ends of the fixed plate 10. A rotation cavity 13 is opened on the upper sides of the front and rear ends of the fixed plate 10. A rotating shaft 11 is provided inside the transmission cavity 12. Both ends of the rotating shaft 11 pass through and extend into the interior of the rotating cavity 13, and the rotating shaft 11 is rotatably connected to the rotating cavity 13. A rotating block 18 is provided inside the rotating cavity 13. The rotating shaft 11 passes through the rotating block 18 and is fixedly connected to the rotating block 18.

[0028] It also includes threaded rods 7, which are rotatably arranged on both sides of the interior of the mobile frame 1. The exterior of the threaded rods 7 is threadedly connected to a lifting block 8. One end of the lifting block 8 extends to the exterior of the mobile frame 1, and the end of the lifting block 8 located outside the mobile frame 1 is connected to the fixed plate 10.

[0029] It also includes a rotating rod 3, which is arranged on both sides of the lower side of the front and rear ends of the mobile frame 1, and the rotating rod 3 is threadedly connected to the mobile frame 1. Both ends of the rotating rod 3 pass through and extend to the outside of the mobile frame 1, and the lower end of the rotating rod 3 is provided with a rubber anti-sliding block 4.

[0030] During use, the mobile frame 1 is easily moved to the top of the conveyor belt through the universal wheel 2, and the first knob 5 is rotated to drive the rotating rod 3 to rotate and press down the rubber anti-sliding block 4 to increase the friction with the ground and stabilize the mobile frame 1. The motor 6 is started and the threaded rod 7 is driven to rotate through the coupling, driving the lifting block 8 to move vertically along the guide groove 9, thereby adjusting the height of the fixed plate 10 to match the conveyor belt. The second knob 17 is rotated to drive the transmission worm 16 to rotate, and the transmission worm wheel 15 and the rotating shaft 11 are driven to rotate synchronously through the worm transmission, thereby driving the rotating block 18 to rotate in the rotating cavity 13, and the adjusting plate 14 rotates accordingly to achieve angle adjustment. The self-locking property of the worm transmission is used to ensure stable adjustment. By adjusting the angles of the two adjustment plates 14, it can adapt to different turns and effectively prevent cartons from falling during transportation.

[0031] See also Figure 2 , a motor 6 is provided below the threaded rod 7, and the output end of the motor 6 is connected to the threaded rod 7 through a coupling. The motor 6 is connected to the threaded rod 7 through a coupling. This direct drive method not only simplifies the power transmission path and reduces energy loss, but also ensures stable transmission and efficient conversion of power;

[0032] See also Figure 2 and Figure 4 , guide grooves 9 are provided on the front and rear sides of the threaded rod 7, and the guide grooves 9 are slidably matched with the lifting block 8. The opening of the guide grooves 9 not only provides a stable guiding effect, but also limits the movement of the lifting block 8 in the horizontal direction, ensuring the verticality and accuracy of the lifting action;

[0033] See also Figure 4 A transmission worm gear 15 is provided on the outer wall of the rotating shaft 11 at one end of the transmission chamber 12, and a transmission worm 16 is rotatably provided on one side of the transmission chamber 12, and both the transmission worm 16 and the transmission worm gear 15 are worm-driven. The worm transmission between the transmission worm gear 15 and the transmission worm 16 not only realizes the effective transmission of power, but also utilizes the self-locking characteristics of the worm transmission, so that the adjustment plate 14 can be maintained at the set angle position without the need for external force maintenance, thereby enhancing the stability and safety of the equipment;

[0034] See also Figure 1 and Figure 4 One end of the transmission worm 16 extends to the outside of the transmission cavity 12, and a second knob 17 is installed on the end of the transmission worm 16 located outside the transmission cavity 12. The setting of the second knob 17 allows the operator to intuitively and conveniently adjust the rotation of the transmission worm 16, thereby controlling the angle of the adjustment plate 14. This design simplifies the operating process, improves work efficiency, and is also convenient for rapid adjustment in emergency situations.

[0035] See also Figure 1 and Figure 2 The upper end of the rotating rod 3 is equipped with a first knob 5. The first knob 5 is directly installed on the upper end of the rotating rod 3, which is convenient for the operator to directly rotate it from above to control the lifting of the rotating rod 3. The operation is more intuitive and labor-saving. At the same time, by directly rotating the first knob 5 to control the lifting of the rotating rod 3, the risk of equipment damage caused by the use of complex tools or improper operation methods is avoided.

[0036] See also Figure 1 and Figure 2Adjustment plates 14 are provided on the front and rear sides of the fixed plate 10, and the adjustment plates 14 are adhered and fixed to one end of the rotating block 18 located outside the rotating cavity 13. The connection between the adjustment plate 14 and the rotating block 18 ensures the synchronization and stability of the adjustment plate 14 during the rotation process, so that the adjustment plate 14 can be accurately and reliably adjusted in angle as needed to adapt to different working environments and operation requirements.

[0037] Working principle: When in use, the mobile rack 1 can be easily moved above the box conveyor belt by rolling the universal wheel 2, and then the first knob 5 is turned. The first knob 5 will drive the rotating rod 3 to rotate synchronously, so that the rotating rod 3 rotates downward, which can drive the rubber anti-sliding block 4 to move downward synchronously. After the rubber anti-sliding block 4 contacts the ground, it can increase the friction force, making the mobile rack 1 more stable, and effectively preventing the mobile rack 1 from sliding or accidentally moving when it stops, ensuring the safety and stability of the operation. After the mobile rack 1 is fixed, the motor 6 can be started. The motor 6 will drive the threaded rod 7 to rotate synchronously through the coupling, and the threaded rod 7 will drive the lifting block 8 to rotate synchronously. Since the front end of the lifting block 8 slides with the two guide grooves 9, the lifting block 8 will be subject to axial limitation, and the rotation of the lifting block 8 will be converted into vertical movement up and down. When the lifting block 8 moves up and down It will drive the synchronous movement of the fixed plate 10, so that the height of the fixed plate 10 can be adjusted, so that the fixed plate 10 can match the height of the conveyor belt, ensuring the subsequent protection effect, turning the second knob 17, the second knob 17 will drive the synchronous rotation of the transmission worm 16, and the worm transmission between the transmission worm 16 and the transmission worm gear 15 will drive the transmission worm gear 15 to make the rotating shaft 11 rotate synchronously. When the rotating shaft 11 rotates, it will drive the rotating block 18 in the rotating cavity 13 to rotate synchronously, and the rotating block 18 will drive the adjusting plate 14 to rotate synchronously, thereby realizing the angle adjustment between the adjusting plate 14 and the fixed plate 10, and because the worm transmission is self-locking, the stability after adjustment is guaranteed, by adjusting the angles of the two adjusting plates 14, it can adapt to different turns, protect the turns, and effectively prevent the cartons from falling through the turns.
