Description

Technical Field

[0001] The utility model relates to the technical field of steel bar feeding machines, in particular to an automatic stepped steel bar feeding device. Background Technique

[0002] With the continuous development of construction projects, the use of steel bars is becoming more and more extensive. In construction projects, the feeding of column steel bars involves cutting, bending, coding, etc. of steel bars, then classifying and segmenting them, and finally transporting these processed steel bars to the construction site to provide the necessary steel bar materials for construction. The main purpose of column steel bar feeding is to provide prefabricated high-quality and high-precision steel bars for the construction site. This method can not only greatly improve the production efficiency and product quality of steel bars, but also significantly reduce the working intensity and time cost at the construction site, and improve the safety and stability of construction projects.

[0003] In the actual processing process, the feeding device of steel bars is time-consuming and laborious, which brings many disadvantages. This will slow down the rhythm of the entire steel bar processing production line. In construction, the supply of steel bars cannot keep up with the construction progress, which may cause construction delays, increase labor costs and management costs. Workers need to spend more time and energy to operate and manage the feeding device. Due to frequent and long-term use, the feeding device is prone to wear, failure and other problems, and requires more frequent maintenance and replacement of parts, which undoubtedly increases the equipment maintenance cost. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an automatic stepped steel bar feeding device that overcomes the above technical problems or at least partially solves the above problems.

[0005] The utility model is implemented as follows:

[0006] The utility model provides an automatic stepped steel bar feeding device, including a manual feeding rack, and a stepped feeding mechanism is arranged on the side of the manual feeding rack. The stepped feeding mechanism includes:

[0007] A main frame, on which a structural cross plate and triangular side plates are arranged. A support bearing seat is arranged on the structural cross plate, and a connecting ring is arranged on the top of the support bearing seat;

[0008] A connecting shaft, which passes through the connecting ring, and an eccentric wheel is arranged on the connecting shaft;

[0009] A variable frequency motor, which is arranged on one side of the main frame through an installation structure, and a speed reducer is arranged on one side of the variable frequency motor;

[0010] Guide rails, which are arranged at both ends of the main frame;

[0011] Intermediate support frame, on which a passive guide wheel is provided through a rotating shaft;

[0012] Moving washboard, which is fixedly connected to the intermediate support frame;

[0013] Fixed washboard, which is fixedly connected to the top of the main frame;

[0014] Fixed cross plate, which is arranged in the middle part of the structure of the main frame.

[0015] In an embodiment of the present invention, triangular side plates are provided at both ends of the guide rail, and both ends of the triangular side plates are fixedly connected to both ends of the main frame.

[0016] In an embodiment of the present invention, the passive guide wheel is located at the side of the eccentric wheel and is in transmission connection with it.

[0017] In an embodiment of the present invention, a plurality of support bearing seats are provided, and the eccentric wheels are arranged at intervals between the support bearing seats.

[0018] In an embodiment of the present invention, the output end of the speed reducer is connected to the connecting shaft, and the input end of the speed reducer is electrically connected to the output end of the frequency conversion motor.

[0019] In an embodiment of the present invention, the guide rail and the intermediate support frame are movably connected through a slide rail block. An adjusting plate is provided on one side of the fixed washboard, and a sensor located on the main frame is provided on one side of the fixed washboard.

[0020] The automatic stepped steel bar feeding device provided by the present invention has the following beneficial effects:

[0021] 1. By setting the stepped feeding mechanism, mechanical automation can perform the feeding operation at a stable and fast rhythm, greatly shortening the feeding time. In large construction sites, traditional manual feeding may only be able to complete a certain amount of steel bar supply in a day, while the automatic feeding device can complete several times the workload in the same time, ensuring that the project progress is not restricted by the steel bar supply.

[0022] 2. Through the setting of the moving washboard, combined with other components, the labor cost is reduced, and the dependence on a large number of manual labor forces is reduced. The feeding work that originally required multiple workers to cooperate can now be monitored by a few personnel for the automatic equipment. This not only saves the direct labor wage expenditure, but also reduces the indirect costs related to labor such as management and training, improves work safety, and avoids the risk of accidental injuries that workers may face in heavy and dangerous feeding operations.

The fixed rubbing plate 210 is fixedly connected to the top of the main frame 201. The fixed cross plate 217 is arranged in the middle of the structure of the main frame 201. Through the setting of the moving rubbing plate 209, combined with other components, the labor cost is reduced, and the dependence on a large number of manual labor forces is reduced.

This not only saves the direct labor wage expenditure, but also reduces the indirect costs related to labor such as management and training, improves work safety, and avoids the risk of accidental injuries that workers may face in heavy and dangerous feeding operations.

[0031] At both ends of the guide rail 208, there are triangular side plates 215. The two ends of the triangular side plates 215 are fixedly connected to the two ends of the main frame 201.
