Technical Field
[0001] This utility model relates to the technical field of electric roller conveyor equipment, and in particular to an electric roller conveyor that can be precisely guided in multiple directions. Background Technology
[0002] Roller conveyors are an indispensable continuous conveying equipment in modern logistics warehousing, production line material transfer, and port terminal cargo sorting.
[0003] In practical applications, existing fixed roller conveyors have limited functionality and suffer from the following problems: Most conveyors are fixed in direction and cannot change the overall conveying orientation according to actual sorting needs. To change the direction of cargo flow, it is usually necessary to install multiple complex conveyors to overlap, which takes up a lot of space and increases the overall cost. For boxes or goods of different sizes, it is necessary to adjust the limit rods on both sides of the conveyor to prevent the goods from deviating or falling off. Adjusting them manually one by one is time-consuming, labor-intensive, and inefficient. Dust, debris, and other waste may be generated during operation, accumulating inside or around the equipment. This not only affects the equipment's lifespan and hygiene but may also cause blockages, requiring frequent manual cleaning and causing considerable inconvenience.
[0004] Therefore, this utility model provides an electric roller conveyor that can be precisely guided in multiple directions. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-directional, precise electric roller conveyor that can change the overall conveying orientation according to actual sorting needs, guide boxes or goods of different sizes, and promptly handle dust, debris, and waste that may be generated during the operation.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-directional precision-guided electric roller conveyor, including a fixed platform.

The electric roller conveyor platform is fitted with a precision blocking mechanism on its top. The precision blocking mechanism includes a first fixed frame, a second electric telescopic rod fixedly connected to the top of the first fixed frame, the output end of the second electric telescopic rod passing through the first fixed frame and fixedly connected to a push rod, a connecting plate fixedly connected to one bottom end of the push rod, an auxiliary baffle installed inside the connecting plate, the auxiliary baffle being located on the top of the electric roller conveyor platform, connecting side plates fixedly connected to both sides of the electric roller conveyor platform, the other side of each connecting side plate being fixedly connected to the first fixed frame, and a second fixed frame fitted on the outer side of the electric roller conveyor platform away from the precision blocking mechanism.
[0007] In a preferred embodiment, a field recycling bin is fixedly connected to the bottom of the fixed platform, and two field recycling pipes located on one side of the support plate are fixedly connected to the top of the field recycling bin. Valves are fixedly connected to the outer sides of each field recycling pipe. An air pump for use with the field recycling pipes is installed inside the field recycling bin. Limiting plates are fixedly connected to the top of the first fixed frame and to both sides of the second electric telescopic rod. Sliding connecting rods are slidably connected inside the two limiting plates. One bottom end of each sliding connecting rod passes through the first fixed frame and is fixedly connected to the top of the connecting plate. A connecting plate with the same structure as the inside of the first fixed frame is installed inside the second fixed frame. A surface cleaning roller is rotatably connected inside the connecting plate located inside the second fixed frame. The first fixed frame is used to assist in obstructing the conveying process during operation, and the second fixed frame is used to perform surface cleaning on the conveyed items.
[0008] In a preferred embodiment, a shock-absorbing frame is fitted around the bottom of the gear. A limiting shaft is rotatably connected inside the shock-absorbing frame, and the top end of the limiting shaft is fixedly connected to the gear. Fifth positioning bolts extending into the interior of the fixed chassis are threaded around the shock-absorbing frame. The shock-absorbing frame and the fifth positioning bolts are used to limit and support the gear during rotation. A third support frame is fixedly connected to the top of the fixed chassis and to one side of the sliding rack. Two second limiting rollers are rotatably connected inside the third support frame. A fourth positioning bolt that matches the limiting of the second limiting rollers is installed on the top of the third support frame. A fixed frame is fixedly connected to the outside of the sliding rack and to the top of the fixed chassis. A control panel is fixedly connected to the outside of the on-site recycling bin.

[0009] In a preferred embodiment, the bottom of the fixed chassis is fixedly connected to equidistantly distributed support base plates. The top of each support base plate and the outer side of the fixed chassis are fixedly connected to a first support frame. The interior of each support base plate is threaded with a second positioning bolt. The top of the fixed chassis is fixedly connected to a plurality of second support frames arranged in a circular structure. The interior of each second support frame is rotatably connected to a first limiting roller used in conjunction with the fixed platform. The interior of each second support frame and both sides of the first limiting roller are threaded with a third positioning bolt extending into the interior of the fixed chassis.
[0010] In a preferred embodiment, a handwheel is installed on one side of each of the two support plates, one end of which is fixedly connected to one end of a corresponding bidirectional lead screw. A bottom support rod is fixedly connected to the bottom of each support plate, and a first mounting base is fixedly connected to the bottom of each bottom support rod. The interior of each first mounting base is threaded with first positioning bolts that are evenly distributed and extend into the interior of the fixed platform. Limiting slide rods are fixedly connected inside the frame and on both sides of the bidirectional lead screw. Both limiting slide rods pass through limiting sliders, and both limiting sliders slide outside the two limiting slide rods. When the limiting sliders move normally, the two limiting slide rods will limit the movement trajectory, which will help with subsequent reset.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting up a fixed platform, fixed chassis, precision blocking mechanism, and orientation guiding mechanism, the control panel activates the first electric telescopic rod. The first electric telescopic rod extends, pushing the connected sliding rack in a linear motion. The sliding rack meshes with the gear, thus converting the linear motion into the rotational motion of the gear. The rotation of the gear drives the rotating disk fixedly connected to it to rotate. Since the top of the rotating disk is fixedly connected to the entire fixed platform, the fixed platform and all equipment on it will rotate together. The second limit roller and the third support frame on one side of the sliding rack ensure the stability of the rack's motion trajectory. Multiple first limit rollers are distributed in a ring at the bottom of the fixed platform, providing rolling support during rotation to ensure smooth rotation and low friction. The shock-absorbing frame and the fifth positioning bolt are used to stabilize the rotation center of the gear. By controlling the first electric... The travel of the telescopic rod can precisely control the rotation angle of the gear. The top of the limit slider is connected to the limit rod, so the distance between the two limit rods changes accordingly. By simply turning the handwheel, the effective width of the conveyor channel can be quickly and symmetrically adjusted to accommodate goods of different specifications. The operation is simple and efficient. When it is necessary to block the goods, a surface cleaning roller is installed in the second fixed frame on the other side of the electric roller conveyor platform. When the goods pass under the cleaning roller, the cleaning roller can brush or adhere to its top surface to remove dust, debris and other dirt. The waste material that is cleaned off and other dust generated on site are sucked into the recycling bin by the air pump in the on-site recycling bin through the on-site recycling pipe for centralized storage, which facilitates subsequent unified cleaning, keeps the site environment clean and avoids equipment blockage.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] like Figures 1-6 As shown, this embodiment provides a technical solution: a multi-directional precision-guided electric roller conveyor, including a fixed platform 1, four support plates 14 are installed on the top of the fixed platform 1, and an electric roller conveyor platform 54 is fixedly connected to the top of each of the four support plates 14. Equally spaced rotating rollers are rotatably connected inside the electric roller conveyor platform 54. A frame 15 is fixedly connected between two support plates 14 on the same side. A bidirectional lead screw 16 is rotatably connected inside the two frames 15 on the same side. Two symmetrically distributed limiting sliders 18 are threadedly connected to the outer side of each bidirectional lead screw 16. The tops of the two limiting sliders 18 are threadedly connected to limiting rods 55 via screws. The limiting rods 55 are located between two adjacent rotating rollers and their length and specifications can be adjusted as needed. In this scheme, a directional guiding mechanism is installed at the bottom of the fixed platform 1. The directional guiding mechanism includes a rotating disk 39. A fixed chassis 2 is installed at the bottom of the fixed platform 1. A gear 38 is rotatably connected to the top of the fixed chassis 2. A sliding rack 32 is slidably connected to one side of the gear 38. The sliding rack 32 meshes with the gear 38.

A rotating disk 39 is fixedly connected to the top of the gear 38. The top of the rotating disk 39 is fixedly connected to the bottom of the fixed platform 1. In this design, a precision blocking mechanism is fitted on the top of the electric roller conveyor platform 54. The precision blocking mechanism includes a first fixed frame 4, with a second electric telescopic rod 41 fixedly connected to the top of the first fixed frame 4. The output end of the second electric telescopic rod 41 passes through the first fixed frame 4 and is fixedly connected to a push rod 42. A connecting plate 43 is fixedly connected to one end of the bottom of the push rod 42. An auxiliary baffle 44 is installed inside the connecting plate 43. The auxiliary baffle 44 is located on the top of the electric roller conveyor platform 54. Connecting side plates 45 are fixedly connected to both sides of the electric roller conveyor platform 54. The other side of the connecting side plates 45 is fixedly connected to the first fixed frame 4. By operating the second electric telescopic rod 41, the push rod 42 is driven to move downward, thereby adjusting the height of the auxiliary baffle 44 located above the electric roller conveyor platform 54 until it is adjusted to the required height, thus limiting and blocking the items conveyed by the electric roller conveyor platform 54. A second fixed frame 48 is fitted on the outer side of the electric roller conveyor platform 54 and the side away from the precision blocking mechanism.
[0016] Going further, such as Figures 1-5 As shown: In this solution, a field recycling box 5 is fixedly connected to the bottom of the fixed platform 1. Two field recycling pipes 52 located on one side of the support plate 14 are fixedly connected to the top of the field recycling box 5. Valves 53 are fixedly connected to the outside of the field recycling pipes 52. An air pump is installed inside the field recycling box 5 to work with the field recycling pipes 52. By operating the air pump inside the field recycling box 5, the two valves 53 are opened, and the waste gas and waste generated during the field operation are recycled and treated through the field recycling pipes 52, which facilitates subsequent manual cleaning and effectively avoids equipment blockage caused by some field waste.
[0017] In this design, limit plates 46 are fixedly connected to the top of the first fixed frame 4 and to both sides of the second electric telescopic rod 41. Sliding connecting rods 47 are slidably connected inside the two limit plates 46. The bottom end of each sliding connecting rod 47 passes through the first fixed frame 4 and is fixedly connected to the top of the connecting plate 43. The second fixed frame 48 has a connecting plate 43 with the same structure as the first fixed frame 4 inside. A surface cleaning roller 49 is rotatably connected inside the connecting plate 43 inside the second fixed frame 48. The first fixed frame 4 is used to assist in conveying obstruction during operation, and the second fixed frame 48 is used to perform surface cleaning on the conveyed items, thereby reducing the labor intensity of manual cleaning.
[0018] Going further, such as Figures 1-6 As shown: In this scheme, a shock-absorbing frame 36 is fitted at the bottom of the gear 38. A limit shaft is rotatably connected inside the shock-absorbing frame 36. The top end of the limit shaft is fixedly connected to the gear 38. The shock-absorbing frame 36 is threaded around its perimeter with a fifth positioning bolt 37 extending into the interior of the fixed chassis 2. The shock-absorbing frame 36 and the fifth positioning bolt 37 are used to limit and support the rotation of the gear 38. A third support frame 33 is fixedly connected to the top of the fixed chassis 2 and to one side of the sliding rack 32. Two second limit rollers 34 are rotatably connected inside the third support frame 33. A fourth positioning bolt 35 is installed on the top of the third support frame 33 to cooperate with the second limit rollers 34 for limiting. A fixed frame 3 is fixedly connected to the outside of the sliding rack 32 and to the top of the fixed chassis 2. The first electric telescopic rod 31 and the sliding rack 32 are limited and installed through the fixed frame 3. The sliding rack 32 slides normally, and the two second limit rollers 34 inside the third support frame 33 on one side limit the sliding trajectory.
[0019] In this scheme, a control panel 51 is fixedly connected to the outside of the on-site recycling bin 5. The first electric telescopic rod 31, the second electric telescopic rod 41, the valve 53 and the electric roller conveyor platform 54 are all electrically connected to the control panel 51. The control panel 51 is used to control the operation of the first electric telescopic rod 31, the second electric telescopic rod 41, the valve 53 and the electric roller conveyor platform 54, realizing unified management of electrical equipment.
[0020] Going further, such as Figures 1-5 As shown in the figure, in this scheme, the bottom of the fixed chassis 2 is fixedly connected with equidistantly distributed support base plates 21, and the top of the support base plates 21 and the outer side of the fixed chassis 2 are fixedly connected with first support frames 22. The inside of the support base plates 21 is threaded with second positioning bolts 23. The second positioning bolts 23 are used to position the corresponding support base plates 21 and the installation position, thereby improving the stability of the equipment during operation.
[0021] In this design, the top of the fixed chassis 2 is fixedly connected to multiple second support frames 24 arranged in a circular structure. The interior of each second support frame 24 is rotatably connected to a first limiting roller 25 used in conjunction with the fixed platform 1. The interior of each second support frame 24, located on both sides of the first limiting roller 25, is threadedly connected to a third positioning bolt 26 extending into the interior of the fixed chassis 2. The second support frame 24 and the fixed chassis 2 are reinforced and connected by the third positioning bolt 26, which facilitates quick disassembly and assembly of individual equipment during maintenance and reduces the labor intensity of daily maintenance.
[0022] Going further, such as Figures 1-5 As shown, in this scheme, handwheels 19 are installed on one side of each of the two support plates 14. One end of the handwheel 19 is fixedly connected to one end of the corresponding bidirectional lead screw 16. By manually rotating the handwheel 19, the corresponding bidirectional lead screw 16 is driven to rotate between the two support plates 14, causing the two outer limit sliders 18 to move towards the center, thereby achieving the effect of adjusting the distance between the two top limit rods 55, which is convenient for flexible adjustment during operation. Bottom support rods 13 are fixedly connected to the bottom of each support plate 14, and a first mounting base 11 is fixedly connected to the bottom of each bottom support rod 13. The interior of the first mounting base 11 is threaded with equidistant... The first positioning bolt 12 extends into the fixed platform 1 and reinforces the bottom support rod 13 and the fixed platform 1 through the first mounting base 11 and the first positioning bolt 12, thereby achieving the effect of reinforcing the connection between the electric roller conveyor platform 54 and the fixed platform 1. Limiting slide rods 17 are fixedly connected inside the frame 15 and on both sides of the bidirectional lead screw 16. Both limiting slide rods 17 pass through the limiting sliders 18, and both limiting sliders 18 slide outside the two limiting slide rods 17. When the limiting sliders 18 move normally, they will limit the movement trajectory through the two limiting slide rods 17, which will help with subsequent reset.
[0023] Working principle: like Figures 1-6 As shown: By setting up a fixed platform 1, a fixed chassis 2, a precision blocking mechanism, and a directional guiding mechanism, the control panel 51 is used to control the operation of the first electric telescopic rod 31, the second electric telescopic rod 41, the valve 53, and the electric roller conveyor platform 54 during use, realizing unified management of the power equipment. When the control panel 51 is turned on, the control panel 51 starts the first electric telescopic rod 31, which extends and pushes the sliding rack 32 connected to it to make linear motion. The sliding rack 32 meshes with the gear 38, thereby converting the linear motion into the rotational motion of the gear. The rotation of the gear 38 drives the rotating disk 39 fixedly connected to it to rotate. Because the top of the rotating disk 39 is connected to the entire fixed platform 41, the control panel 51 controls the operation of the first electric telescopic rod 31, the second electric telescopic rod 41, the valve 53, and the electric roller conveyor platform 54. Platform 1 is fixedly connected, so the fixed platform 1 and all the equipment on it will rotate together. The second limiting roller 34 and the third support frame 33 on one side of the sliding rack 32 ensure the stability of the rack's movement trajectory. Multiple first limiting rollers 25 are distributed in a ring at the bottom of the fixed platform 1, providing rolling support during rotation to ensure smooth rotation and low friction. The shock-absorbing frame 36 and the fifth positioning bolt 37 are used to stabilize the rotation center of the gear 38. By controlling the stroke of the first electric telescopic rod 31, the rotation angle of the gear 38 can be precisely controlled, thereby achieving precise steering of the entire conveyor at any angle within the range of 0-360 degrees, changing the final outflow direction of the goods. The operator turns the handwheel 19, and the handwheel 1... 9 drives the bidirectional lead screw 16 to rotate within the frame 15. Since the threads on the bidirectional lead screw 16 are reversed, when it rotates, the two threaded limit sliders 18 will move closer or further away from each other synchronously along the limit slider 17. The top of the limit slider 18 is connected to the limit rod 55, so the distance between the two limit rods 55 changes accordingly. By simply turning the handwheel, the effective width of the conveying channel can be quickly and symmetrically adjusted to accommodate goods of different specifications. The operation is simple and efficient. When it is necessary to block the goods, the control panel 51 activates the second electric telescopic rod 41. The second electric telescopic rod 41 pushes down, and through the push rod 42 and the connecting plate 43, it drives the auxiliary baffle 44 to descend to a certain height. The auxiliary baffle 44 will block the conveyed goods to achieve precise positioning. The sliding connecting rod 47 and the limiting plate 46 ensure that the push rod assembly will not rotate or deviate during vertical movement, and the movement is smooth. On the other side of the electric roller conveyor platform 54, a surface cleaning roller 49 is installed in the second fixed frame 48. When the goods pass under the cleaning roller, the cleaning roller can brush or adhere to its top surface to remove dust, debris and other dirt. The waste material that is cleaned off and other dust generated on site are sucked into the recycling box 5 by the air pump in the on-site recycling box 5 through the on-site recycling pipe 52 for centralized storage, which is convenient for subsequent unified cleaning, keeps the site environment clean and avoids equipment blockage.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
