Description

Technical Field

[0001] The present application relates to the technical field of material classification, and in particular to a rotary mechanism of a profile rack. Background Art

[0002] The various profiles used in the workshop are mostly randomly piled somewhere in the workshop. When they are needed, they need to be transferred to the processing station by a crane. This operation is time-consuming and labor-intensive, and a lot of space will be wasted when storing the profiles.

[0003] Therefore, the rotary material rack was applied. The rotary material rack can realize the classified storage of profile materials. When needed, you only need to rotate the corresponding material to the material collection table, and then you can take it down, which greatly improves the efficiency of taking and placing profile materials.

[0004] The rotation power of the rotary material rack is mostly provided by the motor driving the main shaft to rotate. When the main shaft rotates to the right position and needs to stop, the main shaft needs to be braked with the help of a drum brake. Due to the large inertia of the material rack, the heat generated by the traditional drum brake is also large, and the main shaft will rotate a certain angle more due to the inertia, thus affecting the material placement. Summary of the invention

[0005] The present application provides a rotating mechanism for a profile rack, which can accurately rotate the profile material to a material taking platform, and the braking responsiveness of the main shaft is good, which can effectively solve the problems in the background technology.

[0007] The brake mechanism includes a positioning frame and a turntable installed on the main shaft. The outer side of the turntable is evenly distributed with multiple positioning grooves. The inner side of the positioning frame is provided with a hydraulic telescopic rod. The telescopic end of the hydraulic telescopic rod is connected to a positioning slider. A positioning plug rod is installed on the positioning slider, and the positioning plug rod is plugged into the positioning groove correspondingly.

[0008] Preferably, the external motor drives the reduction box to operate.

[0009] Preferably, the output shaft of the reduction gearbox is connected to the end of the main shaft through a drum-type gear coupling.

[0010] Preferably, there are two bearing supports, which are respectively installed at two ends of the main shaft.

A mounting hole for the main shaft to pass through is provided in the middle of the outer side surface of the mounting seat, and two symmetrically arranged mounting grooves 2 are provided at the lower end of the inner side surface of the mounting hole. The inner side surface of the mounting groove 2 is rotatably connected to a load-bearing roller, and two symmetrically arranged mounting grooves 1 are provided at the upper end of the inner side surface of the mounting seat. Two symmetrically arranged positioning rollers are rotatably connected to the mounting groove 1, and a baffle is provided on the outer side surface of the mounting seat near the mounting groove.

[0012] Preferably, the brake mechanism is installed on the outer side of the main shaft at one end away from the reduction box.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] 1. The rotating mechanism of the profile rack can accurately rotate the profile material to the material-retrieving table. The braking responsiveness of the spindle is good, and there is basically no heat when the spindle brakes, which not only improves the safety of use, but also increases the service life of the rotating mechanism;

[0019] 2. The number of positioning grooves is not less than one.
