Description

Technical Field

[0001] This utility model belongs to the field of steel bar processing technology, and in particular relates to a conveying device for steel bar processing. Background Technology

[0002] In the construction of buildings, bridges, and other engineering projects, steel bars are core load-bearing components, and their processing quality and efficiency directly affect the overall progress of the project. Currently, the conveying process in steel bar processing mainly relies on various simple conveying equipment, but existing equipment has significant technical shortcomings in practical applications and is difficult to meet the needs of modern processing.

[0003] Existing simple conveying equipment generally adopts a single conveyor belt or roller structure. Since the steel bars are mostly long strips, they are prone to positional deviation during the conveying process, and even multiple steel bars may stack up, causing blockage of the conveying channel and requiring machine shutdown for cleaning, which seriously affects the continuity of conveying. At the same time, the deviated steel bars may also collide with the side wall of the equipment, causing damage to the surface of the steel bars or wear on equipment parts, increasing subsequent maintenance costs. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a conveying device for steel bar processing, which aims to solve the problem that existing conveying devices are prone to positional deviation during the conveying of steel bars, thus affecting the continuity of conveying.

[0005] The present invention adopts the following technical solution:

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-4 As shown, the conveying device for steel bar processing includes a machine base 1. Multiple guide columns 2 are spaced apart on the machine base 1, all inclined forward and downward. A guide plate 3 is provided on the front side wall of each guide column 2, with a baffle groove 4 on the guide plate 3. A material-lifting assembly is provided on the side wall of the guide plate 3. A conveying mechanism and a material-discharging rack 5 are respectively provided at the front and rear ends of the guide columns 2 on the machine base 1. A blocking mechanism is provided inside the machine base 1 directly opposite the outlet of the material-discharging rack 5. The conveying mechanism includes a row of uprights 6. A conveyor wheel 7 is rotatably mounted on the upright frame 6. A slide 8 and a sliding cylinder 9 are provided on the left side of the machine base 1. The drive shaft of the sliding cylinder 9 is connected to the slide 8. A slide seat 10 is provided on the slide 8. A lifting frame 11 is slidably mounted on the slide seat 10. A bidirectional clamping cylinder 12 is provided on the lifting frame 11. The drive shaft of the bidirectional clamping cylinder 12 is provided with a clamping seat 13. A lifting cylinder 14 is provided on the bottom surface of the slide seat 10. The drive shaft of the lifting cylinder 14 is connected to the lifting seat 11.

[0022] In this embodiment, a processing station is set on the left side of the machine, directly opposite the conveying mechanism. The operator places the steel bars to be processed on the feeding rack. Under the action of their own gravity, the steel bars move towards the outlet of the feeding rack. Under the blocking action of the blocking mechanism, the outlet of the feeding rack is closed.

[0023] When this device delivers reinforcing bars in batches to the processing station, the blocking mechanism opens the outlet of the feed rack. Guided by the inclined guide column, the reinforcing bars move forward, with the foremost bar positioned within a groove on the guide plate, achieving initial positioning. Then, the lifting assembly lifts the bar from the groove, causing it to slide along the guide plate onto the conveyor wheel. Next, the lifting cylinder is activated, driving the lifting frame upwards. Before this, the two clamps are open. Once the lifting frame reaches the appropriate position, the front end of the reinforcing bar is positioned within the two clamps. Then, the bidirectional clamping cylinder drives the two clamps to move towards each other, clamping and securing the reinforcing bar. Finally, the sliding cylinder drives the slide to move to the left, and the reinforcing bar is delivered to the processing station for processing.

[0024] Since each guide plate 3 on the machine platform 1 is provided with a baffle 15, the conveying wheel is located between the guide plate and the baffle. The baffle forms a blocking limit, so that when the steel bar leaves the baffle groove, it can be ensured that the steel bar falls accurately onto the conveying wheel.

[0025] In this structure, the feeding rack is wider at the top and narrower at the bottom. When the operator places the steel bars to be processed on the feeding rack, the steel bars move towards the feeding rack outlet under their own weight. This design effectively blocks and releases the steel bars being fed to the feeding rack outlet, preventing excessive feeding due to inertia. Figure 2The blocking mechanism includes a rotatably mounted shaft 16, on which a turntable 17 is mounted opposite each guide post 2. A blocking side plate 18 is mounted on the turntable 17. A driven sprocket 19 is mounted on the shaft 16. An adjusting motor 20 is installed inside the machine base 1. The drive shaft of the adjusting motor 20 has a driving sprocket 21. A matching chain 22 is fitted between the driving sprocket and the driven sprocket 19. In actual conveying, the driving sprocket can be driven to rotate by the adjusting motor. The driving sprocket drives the driven sprocket and the shaft to rotate via the chain, thereby driving the turntable and the blocking side plate to rotate, thus achieving the blocking or release of the reinforcing bars by the blocking side plate.

[0026] To ensure that the reinforcing bars can smoothly detach from the guide plate's groove and enter the subsequent conveying process, Figure 4 In the process, the top material assembly includes a top material cylinder 23, the drive shaft of the top material cylinder is provided with a top material seat 24, and the top surface of the top material seat is formed with a forward and downward inclined pushing surface 25.

[0027] When the reinforcing bar is transferred to the conveyor wheel using the top material assembly, the top material cylinder drives the top material seat to rise, and the pushing inclined surface can apply an upward pushing force to the reinforcing bar, so that the reinforcing bar can smoothly leave the retaining groove along the inclined surface and slide on the guide plate until it falls onto the conveyor wheel.

[0028] In practice, to accommodate the conveying needs of steel bars with different diameters, it is essential to ensure that the steel bars always move along a preset path during conveying, avoiding deviation. For example... Figure 4 The machine base 1 is equipped with a pair of left and right side plates 26, and a long plate 27 is provided on the side plates. A pair of adjusting screws 28 are screwed into the long plate 27. A guide plate 29 is provided at the bottom of the pair of adjusting screws 28. The guide plate and the guide column at the same position form a conveying channel. By rotating the adjusting screws, the distance between the guide plate and the guide column can be adjusted, thereby changing the width of the conveying channel, so that the device can stably convey steel bars of different diameters.

[0029] This invention is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
