Description

Technical Field

[0001] This utility model relates to the technical field of tower tray production and processing equipment, and in particular to a steel coil feeding mechanism for tower tray production. Background Technology

[0002] Tower trays are core components of various tower equipment in industries such as chemical and oil refining. Their production usually begins with the uncoiling, leveling, and cutting of large steel coils. Therefore, efficiently, stably, and accurately transporting heavy steel coils to the processing station is a fundamental step to ensure the smooth operation of the entire tower tray production line and product quality.

[0003] In current production practices, the loading process of steel coils often relies on general lifting equipment such as overhead cranes and forklifts to lift and place them on the conveyor rollers. In this way, it is difficult to accurately control the speed of the steel coil's descent and its final placement posture during operation. This often results in the steel coil falling onto the rollers with a large impact force, which not only easily causes equipment vibration and scratches on the surface of the steel coil, but may also cause the steel coil to deviate from its initial position, making subsequent transmission and positioning difficult.

[0004] When steel coils are placed on roller conveyors and transported to the vicinity of the processing station, precise positioning is required for subsequent equipment to grasp and process them. Traditional positioning methods often use simple fixed blocks or rely on manual assistance for alignment. Using fixed blocks for rigid obstruction causes violent collisions and rebounds of the high-speed moving steel coils, resulting in uncertain final positions and making it difficult to ensure the consistency of positioning points in batch production. Manual assistance is not only inefficient and labor-intensive, but also poses serious safety hazards when dealing with heavy steel coils. This "instability" in the feeding process and the "inaccuracy" in the end-point positioning combine to form the core technical bottleneck in the current steel coil feeding process, directly affecting the automation level and overall efficiency of tray production.

[0005] Therefore, this utility model proposes a steel coil feeding mechanism for tower tray production to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a steel coil feeding mechanism for tower tray production, which aims to improve the problems of unstable steel coil feeding process, easy impact and deviation, and low positioning accuracy after transmission to the processing station in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a steel coil feeding mechanism for tower tray production, including a conveyor table, a lifting mechanism disposed on one side of the conveyor table, and a stopping mechanism disposed on the conveyor table near its conveying end.

[0008] The lifting mechanism includes a fixed frame fixedly connected to the conveyor table, and a guide rail is provided on the fixed frame; the lifting mechanism also includes a pusher table slidably connected to the guide rail; a first electric cylinder is horizontally installed on the fixed frame, and the output end of the first electric cylinder is connected to the pusher table to drive it to reciprocate; a second electric cylinder is vertically installed on the pusher table, and the output end of the second electric cylinder is fixedly connected to a material support frame for lifting the steel coil through an output frame.

[0009] The stopping mechanism includes a side platform fixedly connected to the conveyor table, a motor mounted on the side platform, an output gear fixedly connected to the output shaft of the motor; a fixed column is also rotatably connected to the side platform, a driven gear meshing with the output gear is fixedly connected to the fixed column, and a stopping plate is fixedly connected to the top of the fixed column.

[0010] Preferably, a slide rail is also fixedly connected to the fixed frame, and a slider that slides with the slide rail is provided on the side wall of the material support frame. This structure provides stable guidance for the lifting and lowering movement of the material support frame.

[0011] Preferably, the cylinder body of the first electric cylinder is fixedly connected to the fixed frame, and its piston rod is connected to the push table.

[0012] Preferably, the cylinder body of the second electric cylinder is fixedly connected to the push platform, and its piston rod is connected to the output frame.

[0013] Preferably, the driven gear is coaxially and fixedly connected to the fixed column.

[0014] In one specific implementation, the stop plate, driven by the rotation of the fixed column, can rotate between a receiving position substantially parallel to the conveying plane of the conveying table and a blocking position substantially perpendicular to the conveying plane of the conveying table.

[0015] Preferably, the extension and retraction direction of the first electric cylinder is perpendicular to the conveying direction of the transmission table.

[0016] Preferably, the conveying surface of the conveying table is provided with a plurality of rollers arranged at equal intervals along its conveying direction.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a pusher that moves horizontally driven by a first electric cylinder and a material support that moves vertically driven by a second electric cylinder, and using a slide rail for guidance, the problem of easy shaking and impact during the steel coil feeding process in the prior art, which leads to unstable placement or positional deviation, is solved.

[0021] 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.

[0022] Reference Figures 1-4 The present invention provides an embodiment of a steel coil feeding mechanism for tower tray production, which aims to solve the problems of unstable feeding process and low positioning accuracy of steel coils in the prior art.

[0023] The steel coil feeding mechanism for tower tray production includes a conveyor table 1, a lifting mechanism 2 is provided on one side of the conveyor table 1, and a stopping mechanism 3 is provided near the end of the conveying of the conveyor table 1. The conveyor table 1 serves as the mounting base and conveying channel for the entire mechanism. Several rollers are arranged at equal intervals along the conveying direction on its conveying surface. The lifting mechanism 2 is used to complete the lifting and feeding process of the steel coil, and the stopping mechanism 3 is used to accurately position the steel coil during the conveying process. Specifically, the lifting mechanism 2 includes a fixed frame 201 fixedly connected to the conveyor table 1, with a guide rail on the fixed frame 201. The lifting mechanism 2 also includes a pusher 203 slidably connected to the guide rail. A first electric cylinder 202 is horizontally mounted on the fixed frame 201. The cylinder body of the first electric cylinder 202 is fixedly connected to the fixed frame 201, and its piston rod is connected to the pusher 203 for driving the pusher 203 to slide back and forth along the guide rail. The extension and retraction direction of the first electric cylinder 202 is perpendicular to the conveying direction of the conveyor table 1. A second electric cylinder 204 is vertically mounted on the push table 203. The cylinder body of the second electric cylinder 204 is fixedly connected to the push table 203. The piston rod of the second electric cylinder 204 is fixedly connected to the material support frame 206 through the output frame 205. The material support frame 206 is used to directly support the steel coil. In order to ensure the stability of the lifting process of the material support frame 206, a slide rail 207 is also fixedly connected to the fixed frame 201. The side wall of the material support frame 206 is provided with a slider that slides in cooperation with the slide rail 207. The slide rail 207 provides guidance for the lifting movement of the material support frame 206. The stopping mechanism 3 includes a side platform 301 fixedly connected to the conveyor table 1. A motor 302 is mounted on the side platform 301. An output gear 303 is fixedly connected to the output shaft of the motor 302. A fixed column 305 is also rotatably connected to the side platform 301. A driven gear 304 is fixedly connected to the fixed column 305. The driven gear 304 is coaxially fixedly connected to the fixed column 305, and the driven gear 304 meshes with the output gear 303 for transmission. A stopping plate 306 is fixedly connected to the top of the fixed column 305. The stopping plate 306 can rotate between a receiving position that is substantially parallel to the conveying plane of the conveyor table 1 and a blocking position that is substantially perpendicular to the conveying plane of the conveyor table 1 under the rotation drive of the fixed column 305.

[0024] First, start the lifting mechanism 2. The first electric cylinder 202 is powered on and its piston rod extends to push the push table 203 to slide along the guide rail on the fixed frame 201. The push table 203 then drives the second electric cylinder 204, output frame 205 and material support frame 206 fixed on it to move synchronously to the bottom of the steel coil. Subsequently, the second electric cylinder 204 is activated, and its piston rod extends, driving the material support frame 206 to rise smoothly under the guidance of the slide rail 207 through the output frame 205 until the steel coil is lifted. Then, the piston rod of the first electric cylinder 202 retracts, driving the pusher 203 to move the material support frame 206 holding the steel coil above the conveying surface of the transmission table 1. The piston rod of the second electric cylinder 204 retracts, causing the material support frame 206 to descend smoothly and place the steel coil on the roller of the transmission table 1, thus completing the feeding action. After the steel coil is placed on the conveyor table 1, the rollers inside the conveyor table 1 rotate, driving the steel coil to move towards the processing station along the conveying direction. When the steel coil approaches the preset processing position, the stopping mechanism 3 is activated, the motor 302 is powered on and outputs power, driving the output gear 303, which is fixedly connected to its output shaft, to rotate. The output gear 303 drives the driven gear 304 to rotate through meshing transmission. The fixed column 305, which is coaxially fixed with the driven gear 304, rotates synchronously. The stopping plate 306 at the top of the fixed column 305 rotates from its receiving position, which is basically parallel to the conveying plane, to its blocking position, which is basically perpendicular to the conveying plane. The forward-moving steel coil finally comes into contact with the vertical stopping plate 306 and stops, thus achieving precise positioning.

[0025] The lifting mechanism 2 is fixedly connected to the side of the conveyor table 1 by bolts to the fixed frame 201, providing a stable installation reference for all moving parts of the lifting mechanism 2. The top surface of the fixed frame 201 is machined with a guide rail for guiding the horizontal movement of the push table 203, and the bottom surface of the push table 203 is provided with a corresponding sliding groove that slides with the guide rail. The two form a sliding connection. The cylinder body of the first electric cylinder 202 is horizontally fixed on the fixed frame 201, and the end of its piston rod is fixedly connected to one side wall of the push table 203. When the first electric cylinder 202 works, the extension and retraction of its piston rod can directly drive the push table 203 to perform precise reciprocating linear motion along the length of the guide rail.

[0026] On the top surface of the pusher 203, the cylinder body of the second electric cylinder 204 is vertically fixedly installed. The piston rod end of the second electric cylinder 204 points downward and is fixedly connected to the upper end of the output frame 205. The lower end of the output frame 205 is fixedly connected to the material support frame 206. The material support frame 206 is designed with an arc-shaped structure that can stably support the bottom of the steel coil. By the lifting and lowering movement of the piston rod of the second electric cylinder 204, the material support frame 206 can be driven to achieve vertical lifting and lowering. In order to further enhance the stability of the material support frame 206 during the lifting and lowering process and prevent swaying or tilting due to uneven weight of the steel coil, a slide rail 207 is also fixedly installed vertically on the fixed frame 201. A slider that slides in cooperation with the slide rail 207 is fixedly connected to the side wall of the material support frame 206. The guide cooperation between the slide rail 207 and the slider ensures that the material support frame 206 can move strictly according to the preset vertical trajectory even when carrying heavy objects.

[0027] The side platform 301 of the stopping mechanism 3 is firmly fixed to the side of the conveyor table 1 near the end of the conveying process by welding or bolting, providing a mounting base for the transmission components of the stopping mechanism 3. The base of the motor 302 is fixedly installed on the top surface of the side platform 301, and the output gear 303 is fixedly connected to its output shaft by a key connection. The side platform 301 is provided with a bearing seat, and the fixed column 305 is rotatably connected to the side platform 301 through a rolling bearing installed in the bearing seat, thereby ensuring its rotational flexibility and stability. The driven gear 304 is coaxial. The fixed sleeve is mounted on the fixed column 305 and maintains meshing transmission with the output gear 303. The output gear 303 and the driven gear 304 are both located in the space above the side platform 301. The stop plate 306 is fixedly connected to the top end face of the fixed column 305 away from the side platform 301. Its shape is a rectangular plate structure that can effectively block the end face of the steel coil. When the motor 302 is working, the power is transmitted to the fixed column 305 through the output gear 303 and the driven gear 304, driving the fixed column 305 to rotate the stop plate 306 at a precise angle.

[0028] The internal structure of the conveyor 1 includes a frame consisting of longitudinal beams on both sides and several transverse beams spanning between them. The two ends of the rollers on the conveying surface are rotatably mounted on the longitudinal beams on both sides via bearings. In order to drive the steel coil to move, a drive motor is also installed on one side of the conveyor 1. The output end of the drive motor is connected to all the rollers through a chain drive mechanism to synchronously drive all the rollers to rotate, thereby providing continuous and stable power for the conveying of the steel coil.

[0029] Working principle: During operation, the conveyor 1 provides a channel for the steel coil to be transferred from the lifting station to the processing station. First, the lifting mechanism 2 is started to complete the lifting and loading of the steel coil. The fixed frame 201 of the lifting mechanism 2 is fixed to one side of the conveyor 1 to provide an installation reference for the lifting components. The first electric cylinder 202 is energized to output power and push the pusher 203 to move along the preset trajectory. The pusher 203 drives the second electric cylinder 204 and the output frame 205 to move closer to the steel coil storage position. Then, the second electric cylinder 204 is started to drive the output frame 205 to move. After the support frame 206 supports the bottom of the steel coil, the second electric cylinder 204 pulls the support frame 206 to the processing station until the steel coil is placed stably on the conveyor surface of the processing station, completing the loading process. During this process, the slide rail 207 provides guidance for the lifting and lowering of the support frame 206 to prevent the steel coil from deviating. After the steel coil is placed on the conveyor table 1, the conveyor table 1 starts and drives the steel coil towards the tray processing station through the internal roller structure. When the steel coil is transported to a position close to the preset processing position, the stopping mechanism 3 starts to achieve positioning. The side platform 301 of the stopping mechanism 3 is fixed to the side of the conveyor table 1 near the processing station. The motor 302 is powered and outputs power to drive the output gear 303 to rotate. The output gear 303 meshes with the driven gear 304 and drives the driven gear 304 to rotate synchronously. The stopping plate 306 on the top of the fixed column 305 rises vertically as the fixed column 305 rotates until the stopping plate 306 is higher than the conveying surface of the conveyor table 1. When the steel coil continues to be transported and comes into contact with the stopping plate 306, the stopping plate 306 blocks the steel coil from moving forward and stops the steel coil on the side of the lifting mechanism 2, which is convenient for subsequent tray processing equipment and ensures the stability and accuracy of steel coil feeding in tray production.
