Abstract
Description
Technical Field
[0001] This utility model relates to the field of turning conveyors, and in particular to the buffer structure of the ramp of a turning conveyor. Background Technology
[0002] The ramp buffer structure of a turning conveyor is a device that reduces the inertial impact of materials when turning by using mechanical limits or damping materials. It is used to prevent items from shifting, piling up or breaking during the conveying process, ensuring the continuity of the conveying and the stability of the equipment. It is commonly used in logistics sorting, production lines or warehousing systems to improve transportation efficiency and reduce losses.
[0003] Existing turning conveyors lack the function of ramp material drop buffer. Without the function of ramp material drop buffer, there may be a problem that when the transport path changes, the material may fly out from the turning point due to excessive speed when sliding down the ramp.
[0004] Therefore, in view of the lack of ramp material drop buffer function in the existing turning conveyor, and the problem that the material may fly out from the turning point due to the change of the transportation path, there is an urgent need to design a new type of ramp buffer structure for turning conveyor. Utility Model Content
[0005] To overcome the problem that existing turning conveyors lack the function of ramp material drop buffer, and that materials may fly out from the turning point due to excessive speed when the transport path changes.
[0006] The technical solution of this utility model is as follows: a ramp buffer structure for a turning conveyor, including a turning conveyor body; it also includes a mounting groove 1, a slider 1, a lifting frame, a motor, a lead screw, a slider 2, a mounting plate, damping springs, and baffles. Mounting groove 1 is provided on both the left and right sides of the front front of the upper surface of the turning conveyor body. Sliding slider 1 is slidably connected inside both mounting groove 1. A lifting frame is mounted on the upper surface of slider 1. A motor is installed on the upper surface of the right lifting frame. The output end of the motor passes through the upper surface of the right lifting frame and is connected to a lead screw. The lower surface of the lead screw is rotatably connected to the lower inner surface of the right lifting frame. Sliding slider 2 is threadedly connected to the outer surface of the lead screw. A mounting plate is connected to the left surface of slider 2. One end of a damping spring is provided at each of the four corners of the front surface of the mounting plate. The other ends of the four damping springs are connected to baffles.
[0007] Preferably, by setting a baffle, when the material slides down the ramp, it will be blocked by the baffle to prevent it from falling too fast and flying out of the turning conveyor body. By setting a damping spring, most of the downward impact force can be absorbed, avoiding material damage due to hard contact between the material and the baffle. Finally, by setting a motor, after blocking the material, the start time of the motor is set by an external controller according to the material's downward time interval. After the motor starts, it drives the lead screw to rotate. When the lead screw rotates, it restricts the rotation of the second slider through the lifting frame, thereby driving the first slider to move. When the first slider moves, it drives the mounting plate and its connected parts to move together, thereby raising the baffle to release the material. Then, according to the time set by the external controller, it is lowered to block again. This achieves the purpose of buffering the material falling off the ramp, thus solving the problem that existing turning conveyors lack the function of buffering the material falling off the ramp. Without the function of buffering the material falling off the ramp, there may be a problem that the material may fly out of the turning point due to the high speed when sliding down the ramp due to changes in the transport path.
[0008] Preferably, a limit rod is provided on the inner upper surface of the left lifting frame, and a slider three is slidably connected to the outer surface of the limit rod. The right surface of the slider three is connected to the left surface of the mounting plate.
[0009] Preferably, the rear surface of the mounting plate is provided with one end of a symmetrical connecting rod, and the other end of each connecting rod is connected to a pulley.
[0010] Preferably, one end of a tension spring is connected to the inner front surface of each of the two mounting slots, and the other end of the tension spring is connected to the front surface of its corresponding slider.
[0011] Preferably, the inner rear surface of the two mounting slots is provided with a hydraulic rod, and the telescopic end of the hydraulic rod is connected to the rear surface of the corresponding slider.
[0012] Preferably, each of the two mounting slots 1 has a mounting slot 2 on its inner lower surface, and several rollers are rotatably connected inside the mounting slot 2, with the outer surface of the rollers fitting against the lower surface of the slider 1.
[0013] Preferably, the front surface of the baffle is provided with several weight-reducing grooves, and a rubber pad is installed on the front surface of the baffle.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting baffles, a physical interception interface is formed when the material accelerates down the ramp, effectively controlling the material's acceleration to prevent it from deviating from the running trajectory of the turning conveyor. Then, by setting damping springs, the impact kinetic energy of the material is absorbed through elastic deformation characteristics, establishing a flexible contact interface to avoid the risk of damage caused by rigid collisions between the baffles and the material. Finally, by setting a motor, after the material is intercepted, the start time of the motor is set by an external controller according to the material's descent time interval. When the motor is activated, it drives the lead screw to perform helical motion. During the rotation of the lead screw, the circumferential motion constraint mechanism of the lifting frame on the second slider is used to control the rotation. The motion is converted into the vertical linear displacement of slider one. When slider one moves along the guide rail, it is synchronously pulled by the rigid connection structure to lift and lower the mounting plate and its connected parts together, so as to realize the lifting action of the baffle to release the material interception state. After the release operation is completed, it is lowered according to the time set by the external controller to block again, thereby achieving the purpose of ramp material drop buffering. This solves the problem that the existing turning conveyor lacks ramp material drop buffering function. Without ramp material drop buffering function, there may be a problem that when the transportation path changes, the material may fly out from the turning point due to excessive speed when sliding down the ramp.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-4This utility model provides an embodiment of a ramp buffer structure for a turning conveyor, including a turning conveyor body 1; it also includes mounting groove 1 2, slider 1 3, lifting frame 4, motor 5, lead screw 6, slider 2 7, mounting plate 8, damping spring 9, and baffle 10. Mounting groove 1 2 is provided on both the left and right sides of the front side of the upper surface of the turning conveyor body 1. Slider 1 3 is slidably connected inside both mounting groove 1 2. Lifting frame 4 is mounted on the upper surface of slider 1 3. Motor 5 is provided on the upper surface of right lifting frame 4. The output end of motor 5 passes through the upper surface of right lifting frame 4 and is connected to lead screw 6. The lower surface of lead screw 6 is rotatably connected to the lower inner surface of right lifting frame 4. Slider 2 7 is threadedly connected to the outer surface of lead screw 6. Mounting plate 8 is connected to the left surface of slider 2 7. One end of damping spring 9 is provided at each of the four corners of the front surface of mounting plate 8. The other end of the damping spring 9 is connected to a baffle 10. By setting the baffle 10, when the material slides down the ramp, it will be blocked by the baffle 10 to prevent it from sliding down too fast and flying out of the turning conveyor body 1. By setting the damping spring 9, most of the downward impact force can be absorbed, preventing the material from being damaged due to hard contact with the baffle 10. Finally, by setting the motor 5, after blocking the material, the start time of the motor 5 is set by the external controller according to the material sliding time interval. After the motor 5 starts, it drives the lead screw 6 to rotate. When the lead screw 6 rotates, it restricts the rotation of the second slider 7 through the lifting frame 4, thereby driving the first slider 3 to move. When the first slider 3 moves, it drives the mounting plate 8 and its connected parts to move together, thereby raising the baffle 10 to release the material. Then, according to the time set by the external controller, it is lowered to block again, thus achieving the purpose of buffering the material falling on the ramp.
[0023] Please see Figures 1-3In this embodiment, a limit rod 11 is provided on the inner upper surface of the left lifting frame 4. A slider 12 is slidably connected to the outer surface of the limit rod 11. The right surface of the slider 12 is connected to the left surface of the mounting plate 8. By setting the slider 12, since the slider 12 is connected to the mounting plate 8, the slider 12 moves when the mounting plate 8 moves. The limit rod 11 restricts the degree of freedom of the slider 12, thereby providing support for the other side of the mounting plate 8, thus achieving the purpose of making the mounting plate 8 more stable when it moves. The rear surface of the mounting plate 8 is provided with one end of a left-right symmetrical connecting rod 13. The other end of each connecting rod 13 is connected to a pulley 14. The lower end of the connecting rod 13 is supported by a pulley 14, which serves as the force point for the mounting plate 8. The pulley 14 also prevents friction between the lower end of the connecting rod 13 and the surface of the turning conveyor body 1, thereby enhancing the impact resistance. One end of a tension spring 15 is connected to the front surface of each of the two mounting slots 2, and the other end of the tension spring 15 is connected to the front surface of its corresponding slider 3. By setting the tension spring 15, when the baffle 10 is impacted, the parts connected to the baffle 10 will bear the impact force. The tension spring 15 can effectively release the impact force on the mounting plate 8 as a whole, thereby achieving better force relief.
[0024] Please see Figures 2-4 In this embodiment, hydraulic rods 16 are provided on the rear inner surfaces of the two mounting slots 1-2. The telescopic ends of the hydraulic rods 16 are connected to the rear surfaces of their corresponding sliders 1-3. By providing hydraulic rods 16, when the tension spring 15 releases force, the mounting plate 8 will move backward as a whole. At this time, the hydraulic rods 16 will provide resistance, preventing the tension spring 15 from being overstretched and damaged due to excessive backward impact force, and preventing the mounting plate 8 from shaking severely due to excessive retraction of the tension spring 15. This achieves the purpose of making the tension spring 15 release force more stably. The lower inner surfaces of the two mounting slots 1-2 are each provided with mounting slots 2-17. The inner rotating connection of the mounting groove 17 has several rollers 18. The outer surface of the rollers 18 is in contact with the lower surface of the slider 3. By setting the rollers 18, the two sliders 3 can move without rubbing against the surface of the mounting groove 2, making the movement smoother. This reduces the contact friction of the sliders 3. The front surface of the baffle 10 has several weight-reducing grooves 19 and rubber pads 20 are installed on the front surface of the baffle 10. By setting the weight-reducing grooves 19, the pressure of the motor 5 when driving the mounting plate 8 to rise is reduced. Furthermore, by setting the rubber pads 20, the surface of the baffle 10 is made softer, further protecting the material from damage.
[0025] During operation, slider 12 is connected to mounting plate 8. When mounting plate 8 moves, slider 12 moves along with it. Limiting rod 11 restricts the freedom of slider 12, providing support to the other side of mounting plate 8 and thus ensuring greater stability during movement. Connecting rod 13, with its lower end connected to pulley 14, provides rear support to mounting plate 8. The pulley 14 also prevents friction between the lower end of connecting rod 13 and the surface of the turning conveyor body 1, enhancing impact resistance. A tension spring 15 effectively releases the impact force on mounting plate 8 when baffle 10 is impacted, ensuring that all parts connected to baffle 10 bear the impact force. To achieve better force relief, a hydraulic rod 16 is installed so that when the tension spring 15 relieves force, the entire mounting plate 8 will move backward. At this time, the hydraulic rod 16 will provide resistance to prevent the tension spring 15 from being overstretched due to excessive backward impact force, thus avoiding damage. Also, the tension spring 15 should not retract too abruptly, causing the entire mounting plate 8 to shake violently. This makes the force relief of the tension spring 15 more stable. By installing rollers 18, the two sliders 3 do not need to rub against the surface of the mounting groove 2 when moving, making the movement smoother. This reduces the contact friction of the sliders 3. By installing weight-reducing grooves 19, the pressure on the motor 5 when driving the entire mounting plate 8 to rise is reduced. Furthermore, by installing rubber pads 20, the surface of the baffle 10 is made softer, further protecting the material from damage.
[0026] Through the above steps, by setting baffle 10, a physical interception interface is formed when the material accelerates down the ramp, effectively controlling the material acceleration to prevent it from deviating from the running trajectory of the turning conveyor body 1. Then, by setting damping spring 9, the impact kinetic energy of the material is absorbed through its elastic deformation characteristics, establishing a flexible contact interface to avoid the risk of damage caused by rigid collision between baffle 10 and the material. Finally, by setting motor 5, after the material is blocked, the start time of motor 5 is set by an external controller according to the material's descent time interval. When motor 5 is activated, it drives screw 6 to perform helical motion. During the rotation of screw 6, the circumferential movement of slider 2 7 is supported by lifting frame 4. The binding mechanism converts the rotational motion into the vertical linear displacement of slider 3. When slider 3 moves along the guide rail, it synchronously pulls the mounting plate 8 and its connected parts through the rigid connection structure to lift and lower together, thereby realizing the lifting action of baffle 10 to release the material interception state. After the release operation is completed, it is lowered according to the time set by the external controller to block again, thus achieving the purpose of ramp material drop buffering. This solves the problem that the existing turning conveyor lacks ramp material drop buffering function. Without ramp material drop buffering function, there may be a problem that when the transportation path changes, the material may fly out from the turning point due to excessive speed when sliding down the ramp.
