Description

Technical Field

[0001] This utility model belongs to the field of conveyor lines, and in particular relates to a reversible conveyor line that can turn at right angles. Background Technology

[0002] Right-angle turning conveyor lines are key equipment in automated material handling systems that enable 90° directional switching of materials, and are widely used in food processing, logistics sorting, electronic assembly, and other fields. Their traditional structure mainly consists of two perpendicular straight conveyor belts. At the turning points, a non-powered transition mechanism (such as an arc-shaped baffle, guide roller group, or smooth transition plate) is typically used. The material turning process relies entirely on the combined pushing force of the preceding straight conveyor belt and the frictional force of the following straight conveyor belt.

[0003] The existing conveyor belts lack independent power output at corners, and the speed and posture of materials when turning are completely affected by the force balance of the front and rear conveyor belts. This can easily lead to problems such as turning lag and sudden speed drop. Especially in high-speed conveying scenarios, materials are prone to deviation, falling, or collision with transition mechanisms due to excessive inertia, which not only limits the conveying efficiency but may also cause material damage. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a reversible conveyor line capable of right-angle turns. By setting up an independent turning conveyor mechanism, the drive motor provides dedicated power to the conical rollers and the annular conveyor belt, which makes up for the lack of independent power at traditional corners, avoids material turning delays and sudden speed drops, and at the same time, the protective components can prevent the material from deviating due to centrifugal force, reduce the risk of falling and collisions, and improve conveying efficiency and material safety.

[0005] In view of this, the present invention provides a reversible conveyor line capable of right-angle turns, comprising:

[0006] Two linear conveyors are arranged vertically, and a turning conveyor mechanism is provided between the two linear conveyors. The turning conveyor mechanism is used to realize the right-angle turning and direction change of the material.

[0007] The steering and conveying mechanism includes:

[0008] A fan-shaped turntable, wherein two conical rollers are rotatably connected between the two sides of the inner cavity of the fan-shaped turntable via a sealed bearing;

[0009] An annular conveyor belt is positioned between the outer sides of the two conical rollers;

[0010] A drive motor is fixedly installed on one side of the outer side of the turntable, and the drive end of the drive motor is connected to one end of the tapered roller via a coupling.

[0011] The protective components, located on both sides of the fan-shaped turntable, are designed to prevent materials from falling due to centrifugal force during rapid right-angle turns in the conveyor.

[0012] In this technical solution, by setting up an independent steering and conveying mechanism, the drive motor provides dedicated power to the conical roller and the annular conveyor belt, which makes up for the lack of independent power at the traditional corner, avoids material steering lag and sudden speed drop, and at the same time, the protective components can prevent the material from deviating due to centrifugal force, reduce the risk of falling and collision, and improve conveying efficiency and material safety.

[0013] Furthermore, the diameter of the end face of the conical roller near the inner side of the fan-shaped turntable is smaller than the diameter of the end face of the conical roller near the outer side of the fan-shaped turntable.

[0014] In this technical solution, the inner diameter of the conical roller is smaller than that of the outer diameter, which creates a speed gradient when the annular conveyor belt is running. This adapts to the centrifugal motion requirements when the material turns, helps the material to turn smoothly, and reduces deviation.

[0015] Furthermore, the protective component includes two sector-shaped baffles, and the two sector-shaped baffles are fixedly connected to both sides of the surface of the sector-shaped turntable.

[0016] In this technical solution, two fan-shaped baffles form lateral protection, which can limit the lateral displacement of materials when they turn rapidly, directly blocking the tendency to fall outward due to centrifugal force, and enhancing the stability of conveying.

[0017] Furthermore, buffer strips are affixed to the opposite ends of both of the aforementioned sector-shaped baffles.

[0018] In this technical solution, the buffer strips at opposite ends of the fan-shaped baffle can buffer the contact force between the material and the baffle, which can not only prevent the material from being damaged by collision, but also provide lateral friction force to offset part of the centrifugal force.

[0019] Furthermore, a chassis is provided below the fan-shaped turntable, and a base plate is fixed to the bottom of the fan-shaped turntable. A height adjustment component is installed between the chassis and the base plate. The height adjustment component is used to adjust the height of the fan-shaped turntable to adapt to linear conveyors of different heights. Limiting components are provided between the four corners of the bottom of the fan-shaped turntable and the chassis. The limiting components are used to improve the stability of the fan-shaped turntable after the height is adjusted.

[0020] In this technical solution, the height of the fan-shaped turntable can be flexibly adjusted by the height adjustment component, so that it can be precisely connected with linear conveyors of different heights, avoiding material conveying jams or collisions caused by height mismatch. In addition, the limiting component enhances the structural stability after adjustment, preventing the fan-shaped turntable from shaking and affecting the material posture when turning, thus ensuring smooth conveying.

[0021] Furthermore, the height adjustment component includes:

[0022] A connecting frame, which is inverted U-shaped, is fixedly connected to the chassis;

[0023] A screw is fixedly connected to the bottom end of the base plate, and the end of the screw away from the base plate passes through the connecting frame and extends to the inside of the connecting frame;

[0024] Two nuts are threaded onto the outside of the screws on the upper and lower sides of the connecting frame, respectively.

[0025] In this technical solution, the height adjustment structure of the screw and nut can achieve precise control of the height of the fan-shaped turntable, ensuring a smooth connection with the linear conveyor, avoiding material conveying obstacles caused by height differences, and maintaining the continuity of the turning process.

[0026] Furthermore, the limiting component includes:

[0027] Four support cylinders are fixedly connected to the four corners of the chassis surface;

[0028] Four support columns are fixedly connected to the four corners of the bottom of the fan-shaped turntable, and the four support columns are slidably connected to the four corresponding support cylinders.

[0029] In this technical solution, the sliding cooperation between the support column and the support cylinder forms a guide limit, which prevents the fan-shaped turntable from deviating during height adjustment, enhances the overall structural rigidity, reduces swaying during turning, and avoids material displacement due to structural instability.

[0030] Furthermore, limit grooves are provided at both ends of the inner cavity of the support cylinder, and limit blocks are slidably connected in both limit grooves, and the limit blocks are fixedly connected to the support column inside the support cylinder.

[0031] In this technical solution, the movement trajectory of the support column is further constrained by the cooperation of the limiting groove and the limiting block, preventing it from rotating or shifting laterally inside the support cylinder, ensuring that the fan-shaped turntable remains vertically stable after the height is adjusted, and avoiding collisions or falls caused by structural skew during material conveying.

[0032] Furthermore, both ends of the fan-shaped turntable are fixedly connected to connecting plates, and four connecting plates are threaded with fixing bolts, which are screwed into the connecting plates.

[0033] In this technical solution, the fan-shaped turntable and the linear conveyor can be firmly connected by the cooperation of the connecting plate and the fixing bolt, which reduces the vibration gap when turning, prevents the material from shifting or falling at the junction due to loose connection, and improves the stability of the overall conveying system.

[0034] The beneficial effects of this utility model are:

[0035] 1. This utility model, by setting up an independent steering and conveying mechanism, provides dedicated power to the conical roller and the annular conveyor belt through a drive motor, which makes up for the lack of independent power at the traditional corners, avoids material steering lag and sudden speed drop, and at the same time, the protective components can prevent the material from deviating due to centrifugal force, reduce the risk of falling and collision, and improve conveying efficiency and material safety.

[0036] 2. This utility model allows for flexible adjustment of the height of the fan-shaped turntable via a height adjustment component, enabling precise docking with linear conveyors of different heights. This avoids material conveying jams or collisions caused by height mismatches. Furthermore, the limiting component enhances the structural stability after adjustment, preventing the fan-shaped turntable from swaying during turning and affecting the material's posture, thus ensuring smooth conveying.

[0037] 3. This utility model can firmly connect the fan-shaped turntable and the linear conveyor by the cooperation of the connecting plate and the fixing bolt, reduce the vibration gap during turning, prevent the material from shifting or falling at the junction due to loose connection, and improve the stability of the overall conveying system.

Additionally, features described with reference to certain examples may be combined in other examples.

[0048] Example 1:

[0049] like Figure 1 and Figure 4 As shown, this utility model provides a right-angle turning deflection conveyor line, comprising: two linear conveyors 1, which are commonly used belt conveyors, the two linear conveyors 1 are vertically distributed, and a turning conveyor mechanism is provided between the two linear conveyors 1. The turning conveyor mechanism is used to realize the right-angle turning of materials; the turning conveyor mechanism includes: a fan-shaped turntable 2, two conical rollers 22 are rotatably connected between the two sides of the inner cavity of the fan-shaped turntable 2 through sealed bearings, and the arc of the fan-shaped turntable 2 is 90°; an annular conveyor belt 21 is provided between the outer sides of the two conical rollers 22; a drive motor 23 is fixedly installed at one end of the outer side of the fan-shaped turntable, and the drive end of the drive motor 23 is connected to one end of the conical roller 22 through a coupling; and protective components on both sides of the surface of the fan-shaped turntable 2 to prevent materials from falling due to centrifugal force during rapid right-angle turning.

[0050] During operation, the conical roller 22 is independently driven to rotate by the drive motor 23, which in turn drives the annular conveyor belt 21 to run. The tension guide wheel is embedded in the sheet metal guide rail (not shown) to prevent the belt from shifting laterally. This provides dedicated power for material turning, eliminating the dependence on the force balance of the front and rear linear conveyors 1. It avoids turning delay and sudden speed drop caused by insufficient power. When the annular conveyor belt 21 actively drives the material to turn with the fan-shaped turntable 2, the protective components block the deviation caused by centrifugal force, reducing the risk of material falling or colliding, and ensuring stability and safety during rapid conveying.

[0051] The diameter of the end face of the conical roller 22 near the inner side of the fan-shaped turntable 2 is smaller than the diameter of the end face of the conical roller 22 near the outer side of the fan-shaped turntable 2.

[0052] By designing the inner diameter of the conical roller 22 to be smaller than that of the outer diameter, the annular conveyor belt 21 forms a speed gradient with a higher linear velocity on the outer side than on the inner side during operation. This adapts to the centrifugal motion characteristics of the material when it turns, ensuring that the material is subjected to balanced forces in all parts during the turning process, reducing posture disorder caused by speed mismatch, and achieving a smooth transition.

[0053] The protective component includes two sector-shaped baffles 3, and the two sector-shaped baffles 3 are fixedly connected to both sides of the surface of the sector-shaped turntable 2.

[0054] Two fan-shaped baffles 3 are distributed along both sides of the fan-shaped turntable 2, forming a lateral constraint on the material synchronously with the turntable. When the material turns quickly and is subjected to centrifugal force, it tends to shift outward. The baffles can directly block its lateral displacement. With the driving force of the annular conveyor belt 21, the material is kept moving stably within the turning path to avoid being thrown off.

[0055] Each of the two fan-shaped baffles 3 has a buffer strip 31 attached to one end of its opposite side. The buffer strip 31 is made of polyurethane.

[0056] When the material comes into contact with the baffles, the buffer strips 31 at opposite ends of the two fan-shaped baffles absorb the collision energy through their own deformation, reducing the damage to the material caused by the impact. At the same time, the friction on the surface of the buffer strips 31 can help correct the material's posture, offset some of the centrifugal force, and further improve the stability during the turning process.

[0057] Example 2:

[0058] like Figure 2-3 As shown, a base plate 5 is provided below the fan-shaped turntable 2, and a base plate 6 is fixed to the bottom end of the fan-shaped turntable 2. A height adjustment component is installed between the base plate 5 and the base plate 6. The height adjustment component is used to adjust the height of the fan-shaped turntable 2 to adapt to linear conveyors 1 of different heights. Limiting components are provided between the four corners of the bottom end of the fan-shaped turntable 2 and the base plate 5. The limiting components are used to improve the stability of the fan-shaped turntable 2 after the height is adjusted.

[0059] By adjusting the height of the fan-shaped turntable 2, the turning conveyor mechanism can be precisely connected with the linear conveyor 1 at different heights, avoiding collisions or jamming of materials at the connection point due to height differences. In addition, the limiting component provides stable support for the fan-shaped turntable 2 after height adjustment, reducing swaying during the turning process and ensuring the stability of the material's posture during conveying and turning, thus reducing the risk of deviation.

[0060] The height adjustment assembly includes: a connecting frame 62, which is inverted U-shaped and is fixedly connected to the chassis 5; a screw 61, which is fixedly connected to the bottom end of the base plate 6, and the end of the screw 61 away from the base plate 6 passes through the connecting frame 62 and extends to the inner side of the connecting frame 62; and two nuts 63, which are respectively threaded onto the outer side of the screw 61 on the upper and lower sides of the connecting frame 62.

[0061] During operation, by loosening or tightening the nuts 63 on the upper and lower sides of the connecting frame 62, the screw 61 and the base plate 6 can be raised and lowered, so as to achieve fine adjustment of the height of the fan-shaped turntable 2, ensuring that it is flush with the conveying surface of the front and rear linear conveyors 1, avoiding sudden speed drop or collision of materials due to height difference during transition, and ensuring the continuity of conveying.

[0062] The limiting component includes: four support cylinders 53, which are fixedly connected to the four corners of the surface of the chassis 5; and four support columns 51, which are fixedly connected to the four corners of the bottom of the fan-shaped turntable 2, and are slidably connected to the corresponding four support cylinders 53.

[0063] By having the support column 51 slide synchronously within the support cylinder 53 as the height of the fan-shaped turntable 2 is adjusted, four corner limits are formed on the fan-shaped turntable 2, restricting its lateral displacement, enhancing the structural stability after height adjustment, preventing the fan-shaped turntable 2 from shifting due to vibration generated by the operation of the drive motor 23 during turning, and ensuring the stability of the material conveying path.

[0064] Limiting grooves 54 are provided at both ends of the inner cavity of the support cylinder 53. Limiting blocks 52 are slidably connected in both limiting grooves 54, and the limiting blocks 52 are fixedly connected to the support column 51 inside the support cylinder 53.

[0065] When the support column 51 slides, the limiting block 52 moves synchronously within the limiting groove 54 of the support cylinder 53, which can prevent the support column 51 from detaching from the support cylinder 53, further enhance the constraint effect of the limiting component, improve the overall rigidity of the fan-shaped turntable 2 when turning at high speed, and reduce material displacement or falling due to structural shaking.

[0066] Example 3:

[0067] like Figure 1 and Figure 4 As shown, both ends of the fan-shaped turntable 2 are fixedly connected to connecting plates 4, and four connecting plates 4 are threaded through by fixing bolts 41, and the fixing bolts 41 are threadedly connected to the connecting plates 4.

[0068] By placing the connecting plates 4 on both sides of the fan-shaped turntable 2 onto the frame on both sides of the linear conveyor 1, and then tightening the fixing bolts 41 to contact the frame surface of the linear conveyor 1, the stability of the fan-shaped turntable 2 connected to the linear conveyor 1 is improved, the connection rigidity is enhanced, and the material is prevented from getting stuck or colliding due to gaps during the transition, ensuring smooth power transmission and maintaining a stable conveying speed.

[0069] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
