Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, and in particular to a box-type rotary reversing device. Background Technology

[0002] Traditional roller conveyor reversing typically uses a 90° in-situ rotary table or a lifting reversing device as the reversing mechanism for the conveyor line. However, using an in-situ rotary table requires a certain amount of rotation and turning space, and the distance between the front and rear rollers cannot be too close, otherwise it will affect the conveying cycle of the roller conveyor line, which places certain space requirements on it. In addition, in-situ rotary tables are generally more complex in structure and larger in size, with a correspondingly higher failure rate, cost, and energy consumption. On the other hand, lifting reversing devices require a height difference between the transverse and longitudinal tracks to avoid interference, and the height of the rollers will rise and fall before and after reversing, which will affect the stability of material conveying. Utility Model Content

[0003] This invention provides a box-type rotary reversing device, which solves the problems of limited reversing angle, high space requirements, and poor stability in the prior art.

[0004] The technical solution of this utility model is as follows: A box-type rotary reversing device includes a box-type frame. The upper surface of the box-type frame is provided with a circular mounting groove. A rotatable track mechanism is installed in the circular mounting groove. A rotary support frame is fixedly connected below the track mechanism. A support base is installed below the rotary support frame. A drive motor and a reducer connected to the output end of the drive motor are installed on the support base. The center of the rotary support frame is connected to the output end of the reducer through a rotating shaft. Multiple traveling wheels are installed around the axis of the rotating shaft at the lower end of the rotary support frame. The traveling wheels are in rolling contact with the upper surface of the support base.

[0005] Preferably, the track mechanism includes two parallel rows of roller conveyors and multiple conveyor rollers mounted between the two rows of roller conveyors.

[0006] Preferably, the rotating support frame includes:

[0007] A cross-shaped support, the center of which is rotatably connected to a rotating shaft via a bearing;

[0008] A pair of U-shaped support frames are symmetrically fixed to the ends of the first pair of radial arms of the cross-shaped bracket;

[0009] A pair of support crossbars are symmetrically fixed to the ends of the second pair of radial arms of the cross-shaped bracket, and both ends extend to near the U-shaped support frame;

[0010] Two extended square tubes are vertically fixed to the outer ends of the supporting crossbar.

[0011] Preferably, the upper end of the U-shaped support frame is screwed to the track mechanism via a gasket, and both ends of the support crossbar are screwed to the bottom of the double-row roller conveyor via pads. Conveying short rollers are mounted on the two extended square tubes.

[0012] Preferably, a photoelectric sensor is installed on the support base near the travel track of the walking wheel.

[0013] Preferably, the conveying short roller is connected to the conveying roller via a closed chain drive.

[0014] Preferably, a photoelectric sensor is installed on the support base near the travel track of the walking wheel.

[0015] The beneficial effects of this utility model are as follows: The box-type frame integrates a circular mounting groove and a rotatable track mechanism, allowing the conveyor rollers to accurately change direction within a 180° range. Only a single device is needed to replace the traditional multi-stage steering system, significantly reducing the floor space required, making it particularly suitable for assembly line layouts with limited space. The rotating support frame adopts a composite structure that combines a cross-shaped bracket, a U-shaped support frame, a support crossbar, and an extended square tube, greatly enhancing bending stiffness and improving the load-bearing capacity of the equipment. The rotatable track mechanism solves the problem of centrifugal deviation during material rotation and conveying by using a layout where the traveling wheels and the support base roll in contact, and ensures the rotational stability of the track mechanism.

[0020] Combined with appendix Figure 1 The present invention provides a further description of the box-type rotary reversing device.

[0021] This utility model discloses a box-type rotary reversing device, including a box-type frame 1. The upper surface of the box-type frame 1 is provided with a circular mounting groove 1-1. A rotatable track mechanism 2 is installed in the circular mounting groove 1-1. A rotary support frame 3 is fixedly connected below the track mechanism 2. A support base 4 is installed below the rotary support frame 3. A drive motor 5 and a reducer connected to the output end of the drive motor 5 are installed on the support base 4. The center of the rotary support frame 3 is connected to the output end of the reducer through a rotating shaft 6. Multiple traveling wheels 7 are installed around the axis of the rotating shaft 6 at the lower end of the rotary support frame 3. The traveling wheels 7 are in rolling contact with the upper surface of the support base 4.

[0022] Furthermore, the track mechanism 2 includes parallel double-row roller conveyor plates 2-1 and multiple conveyor rollers 2-2 erected between the double-row roller conveyor plates 2-1.

[0023] Furthermore, the rotating support frame 3 includes:

[0024] The cross-shaped bracket 3-1 is rotatably connected to the rotating shaft 6 via a bearing 3-2 at its center;

[0025] A pair of U-shaped support frames 3-3 are symmetrically fixed to the ends of the first pair of radial arms of the cross-shaped bracket 3-1;

[0026] A pair of support crossbars 3-4 are symmetrically fixed to the ends of the second pair of radial arms of the cross-shaped bracket 3-1, and both ends extend to near the U-shaped support frame 3-3;
