Description

Technical Field

[0001] This utility model belongs to the technical field of material ejection devices, and in particular relates to a material ejection device for a small-diameter steel bar welding platform. Background Technology

[0002] Small-diameter steel bars typically refer to steel bars with a diameter of no more than 10mm, such as Φ6, Φ8, and Φ10. In construction engineering, they are often used for structural reinforcement, stirrups, or distribution bars of components, serving to fix the main reinforcement, bear local stress, or achieve structural connections.

[0003] However, due to their small diameter, small-diameter steel bars are prone to falling or colliding with each other during the unloading process after welding. Such collisions can not only cause scratches, dents, and other damage to the surface of the steel bars, affecting their appearance quality, but also cause micro-cracks or deformations in the internal structure of the steel bars, thereby reducing their mechanical properties and failing to meet the strict quality requirements for steel bars in construction and other projects.

[0004] To address these issues, we provide a material ejection device for a small-diameter steel bar welding platform. Utility Model Content

[0005] The purpose of this utility model is to provide a material unloading device for a small-diameter steel bar welding platform. By having the rear conveyor belt rotate in opposite directions to the front conveyor belt, the steel bars entering the rear buffer chamber are firmly clamped and driven to move downward at a uniform speed, which solves the problem that existing thin steel bars are easily damaged by collisions during unloading.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a material unloading device for a small-diameter steel bar welding platform, including a base frame; a material pushing component is provided on the top of the base frame, and a buffer component for reducing the falling speed of the thin steel bars is provided on the front of the base frame.

[0008] The feeding assembly includes an upwardly inclined receiving screen fixedly connected to the top of the base frame, an electric push rod fixedly connected to the back of the base frame, a push plate slidably connected to the output end of the electric push rod, and a downwardly inclined discharge chute fixedly connected to the output port of the receiving screen.

[0009] The buffer assembly includes a rear buffer chamber fixedly connected to the front of the base frame, a front buffer chamber fixedly connected to the front of the rear buffer chamber, a rear drive roller and a rear driven roller rotatably connected inside the rear buffer chamber, a rear conveyor belt externally connected to the rear drive roller and the rear driven roller, a front drive roller rotatably connected inside the front buffer chamber near the top, tensioners fixedly connected to both sides of the front buffer chamber near the bottom, a front driven roller installed between the two tensioners, and a front conveyor belt externally connected to the front driven roller and the front drive roller.

[0010] The present invention is further configured such that a rear drive motor is fixedly connected to the side of the rear buffer chamber, and the shaft of the rear drive roller is fixedly connected to the output end of the rear drive motor; a front drive motor is fixedly connected to the side of the front buffer chamber, and the shaft of the front drive roller is fixedly connected to the output end of the front drive motor.

[0011] The present invention is further configured such that multiple rear pressure rollers are rotatably connected at equal intervals from top to bottom inside the rear buffer chamber, and an adjustment assembly is provided inside the front buffer chamber.

[0012] The present invention is further configured such that the adjusting component includes a mounting frame slidably connected to the inside of the front buffer chamber, and a plurality of front pressure rollers equidistantly distributed from top to bottom are rotatably connected inside the mounting frame. Two sliding openings are opened on both sides of the front buffer chamber, and a sliding frame is slidably connected inside the sliding opening. The mounting frame is fixedly connected to the inside of the sliding frame. An adjusting bolt is rotatably connected to the center of the front of the front buffer chamber, and the sliding frame is threaded onto the outside of the adjusting bolt.

[0013] The present invention is further configured such that the two tensioners include slide plates fixedly connected to both sides of the front buffer chamber, and the slide plates are connected to the front buffer chamber. Sliders are slidably connected inside the two slide plates, and the front driven roller is rotatably connected between the two sliders. A spring is installed between the top of the slider and the inner wall of the slide plate.

[0014] The present invention is further configured such that the top and bottom of the slider are fixedly connected to slide rods that are movably sleeved inside the slide plate, and the springs are movably sleeved outside the slide rods located above.

[0015] The present invention is further configured such that a scale is fixedly connected to the front of the front buffer compartment, and the scale is movably sleeved inside the sliding frame.

[0016] The present invention is further configured such that an inclined downward slag discharge trough is fixedly connected inside the base frame, and the slag discharge trough is located directly below the receiving screen.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model allows welding slag to fall into the slag discharge trough through the screen holes of the receiving screen, avoiding the welding slag from being mixed with the thin steel bars. Then, the output end of the electric actuator drives the push plate to slide along the inside of the receiving screen, automatically pushing the steel bars on the receiving screen to the output port of the receiving screen. Subsequently, the steel bars slide down the inclined downward discharge trough and fall into the buffer assembly by their own gravity, which can automatically discharge the welded steel bars.

[0019] 2. This utility model starts the rear drive motor, which drives the rear drive roller to rotate. Through the transmission between the rear conveyor belt and the rear drive roller and the rear driven roller, the rear conveyor belt starts to run. At the same time, the front drive motor is started, which drives the front drive roller to rotate. Through the transmission between the front conveyor belt and the front drive roller and the front driven roller, the front conveyor belt starts to run. The rear conveyor belt rotates in opposite directions to the front conveyor belt, which firmly clamps the steel bars entering the rear buffer chamber and drives the steel bars to move down at a uniform speed. This avoids deformation or surface damage to the steel bars due to high-speed collisions, thus ensuring the quality of the steel bars. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0029] Please see Figures 1 to 3 This utility model is a material ejection device for a small diameter steel bar welding platform, including a base frame 100; a material pushing component 200 is provided on the top of the base frame 100, and a buffer component 300 for reducing the falling speed of the thin steel bars is provided on the front of the base frame 100.

[0030] The feeding assembly 200 includes an upwardly inclined receiving screen 201 fixedly connected to the top of the base frame 100. An electric push rod 202 is fixedly connected to the back of the base frame 100. A push plate 204 slidably connected inside the receiving screen 201 is fixedly connected to the output end of the electric push rod 202. An downwardly inclined discharge trough 203 is fixedly connected to the output port of the receiving screen 201. The upwardly inclined design of the receiving screen 201 uses gravity to make the welding slag slide down the screen surface and fall directly into the discharge trough 205 below through the screen holes, avoiding the accumulation of welding slag from affecting the conveying of steel bars, reducing the frequency of manual cleaning, and improving the material return efficiency. The electric push rod 202 drives the push plate 204 to slide along the receiving screen to realize the automatic pushing of steel bars and reduce the intensity of manual operation. The inclination angle of the discharge trough 203 is adapted to the sliding trajectory of the steel bars to ensure that the material smoothly transitions to the buffer assembly 300.

[0031] Specifically, the base frame 100 has an inclined downward slag discharge trough 205 fixedly connected inside, and the slag discharge trough 205 is located directly below the receiving screen 201.

[0032] The operation process of this embodiment is as follows: After the thin steel bar is welded, the steel bar falls onto the receiving screen 201. Then, the welding slag falls into the slag discharge trough 205 through the screen holes of the receiving screen 201 and is discharged to avoid the welding slag from being mixed in with the thin steel bar. Next, the push plate 204 is driven by the output end of the electric push rod 202 to slide along the inside of the receiving screen 201, and the steel bar located on the receiving screen 201 is automatically pushed to the output port of the receiving screen 201. Then, the steel bar slides down the inclined downward discharge trough 203 and falls into the buffer assembly 300 by its own gravity, and the welded steel bar can be automatically discharged. Example

[0033] Please see Figure 2 , Figure 4 and Figure 5 Based on the first specific embodiment, the buffer assembly 300 includes a rear buffer chamber 301 fixedly connected to the front of the base frame 100. A front buffer chamber 313 is fixedly connected to the front of the rear buffer chamber 301. A rear drive roller 302 and a rear driven roller 303, distributed vertically, are rotatably connected inside the rear buffer chamber 301. A rear conveyor belt 304 is drively connected to the outside of the rear drive roller 302 and the rear driven roller 303. A front drive roller 306 is rotatably connected near the top of the front buffer chamber 313. Tensioners 307 are fixedly connected to both sides of the bin 313 near the bottom. A front driven roller 308 is installed between the two tensioners 307. The front driven roller 308 and the front drive roller 306 are externally connected by a front conveyor belt 309. The rear conveyor belt 304 and the front conveyor belt 309 can clamp the thin steel bars. Then, by the rear conveyor belt 304 and the front conveyor belt 309 rotating in opposite directions, the thin steel bars can be driven to move down at a uniform speed, reducing the impact force of the falling steel bars and avoiding deformation or surface damage to the steel bars due to high-speed collision.

[0034] Specifically, a rear drive motor 311 is fixedly connected to the side of the rear buffer chamber 301, and the shaft of the rear drive roller 302 is fixedly connected to the output end of the rear drive motor 311. A front drive motor 312 is fixedly connected to the side of the front buffer chamber 313, and the shaft of the front drive roller 306 is fixedly connected to the output end of the front drive motor 312.

[0035] Furthermore, the two tensioners 307 include grooving plates 307a fixedly connected to both sides of the front buffer chamber 313, and the grooving plates 307a are connected to the front buffer chamber 313. Slider blocks 307b are slidably connected inside the two grooving plates 307a, and the front driven roller 308 is rotatably connected between the two sliders 307b. A spring 307d is installed between the top of the slider 307b and the inner wall of the grooving plate 307a. The elastic force of the spring 307d in the tensioner 307 pushes the slider 307b, so that the front driven roller 308 automatically compensates for the slack caused by the wear of the conveyor belt and maintains the tension of the conveyor belt.

[0036] The top and bottom of the slider 307b are fixedly connected to the slide rod 307c, which is movably sleeved inside the slide plate 307a, and the spring 307d is movably sleeved outside the slide rod 307c located above.

[0037] The operation process of this embodiment is as follows: When the steel bar slides from the discharge chute 203 to the buffer assembly 300, the rear drive motor 311 is started, which drives the rear drive roller 302 to rotate. Through the transmission between the rear conveyor belt 304 and the rear drive roller 302 and the rear driven roller 303, the rear conveyor belt 304 starts to run. At the same time, the front drive motor 312 is started, which drives the front drive roller 306 to rotate. Through the transmission between the front conveyor belt 309 and the front drive roller 306 and the front driven roller 308, the front conveyor belt 309 starts to run. The rear conveyor belt 304 rotates in opposite directions to the front conveyor belt 309, which firmly clamps the steel bar that has entered the rear buffer chamber 301 and drives the steel bar to move down at a uniform speed, avoiding deformation or surface damage to the steel bar due to high-speed collision and ensuring the quality of the steel bar. Example

[0038] Please see Figure 4 and Figure 5 Based on specific embodiment one and specific embodiment two, multiple rear pressure rollers 305 are rotatably connected from top to bottom inside the rear buffer chamber 301, and an adjustment assembly 310 is provided inside the front buffer chamber 313.

[0039] Specifically, the pitch adjustment assembly 310 includes a mounting frame 310a slidably connected inside the front buffer chamber 313. Multiple front pressure rollers 310b, evenly distributed from top to bottom, are rotatably connected inside the mounting frame 310a. Two sliding openings 313a are opened on both sides of the front buffer chamber 313. A sliding frame 310c is slidably connected inside the sliding opening 313a, and the mounting frame 310a is fixedly connected inside the sliding frame 310c. An adjusting bolt 310d is rotatably connected at the center of the front of the front buffer chamber 313, and the sliding frame 310c is threaded onto the outside of the adjusting bolt 310d. Rotating the adjusting bolt 310d can drive the sliding frame 310c to move back and forth, and the pitch between the rear conveyor belt 304 and the front conveyor belt 309 can be adjusted according to the diameter of the reinforcing bar.

[0040] Furthermore, a scale 310e is fixedly connected to the front of the front buffer compartment 313, and the scale 310e is movably sleeved inside the sliding frame 310c.

[0041] The operation process of this embodiment is as follows: When it is necessary to process steel bars of different diameters, firstly, the adjusting bolt 310d is manually rotated. Then, since the sliding frame 310c is threaded onto the outside of the adjusting bolt 310d, the sliding frame 310c will move back and forth along the adjusting bolt 310d, thereby driving the mounting frame 310a fixedly connected inside the sliding frame 310c to move. The front pressure roller 310b inside the mounting frame 310a also moves accordingly, realizing the function of adjusting the distance between the rear conveyor belt 304 and the front conveyor belt 309 according to the diameter of the steel bar. It can adapt to the unloading needs of small diameter steel bars of different diameters, and improve the versatility and applicability of the equipment.
