Description

Technical Field

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

[0002] After the steel bars are processed, they are usually bundled for easy transportation or storage. Large-diameter straight steel bars are usually transported to the bundling machine in loose bundles, where they are vigorously impacted to align them before being bundled together, resulting in good alignment and easy bundling.

[0003] Unlike large-diameter steel bars, small-diameter coiled steel bars (5-12mm) need to be straightened by cold rolling. Because the steel bars are thin, using a forceful impact to straighten them can cause them to bend. Therefore, small-diameter steel bars are usually straightened manually, which is inefficient. Moreover, when small-diameter steel bars are bundled loosely and moved toward the binding machine, the friction between the steel bars is small due to their thinness and small ribs, resulting in inconsistent movement speeds and increasingly uneven bundles. Utility Model Content

[0004] The purpose of this utility model is to provide a steel bar bundling device to solve the problems of low bundling efficiency and uneven bundling of small-diameter straight steel bars.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A rebar bundling device includes a roller conveyor, a first bundling mechanism, a second bundling mechanism, an alignment mechanism, and a clamping mechanism. The roller conveyor is used to transport rebar bundles. The first bundling mechanism and the second bundling mechanism are spaced apart along the transport direction of the roller conveyor. The alignment mechanism is located upstream of the first bundling mechanism and is used to push the ends of the rebars. The clamping mechanism is used to clamp the rebar bundles. At least the clamping mechanism is provided before and after the first bundling mechanism.

[0007] In one embodiment, the alignment mechanism includes an alignment drive and a pusher plate, wherein the alignment drive is used to push the pusher plate to move along the conveying direction of the roller conveyor.

[0008] In one embodiment, the first binding mechanism is a piercing binding machine, and the distance between the first binding mechanism and the second binding mechanism is greater than the length of the reinforcing bar.

[0009] In one embodiment, the second strapping mechanism is a ring strapping machine.

[0010] In one embodiment, the clamping mechanism includes a first clamping arm, a second clamping arm, a clamping seat, a first clamping drive member, and a second clamping drive member. The first clamping arm and the second clamping arm are both rotatably mounted on the clamping seat. The first clamping drive member is connected to the first clamping arm and is used to drive the first clamping arm to rotate. The second clamping drive member is connected to the second clamping arm and is used to drive the second clamping arm to rotate.

[0011] In one embodiment, the clamping mechanism includes a first clamping arm, a second clamping arm, a clamping seat, a clamping drive component, and a transmission assembly. The first clamping arm and the second clamping arm are rotatably mounted on the clamping seat. The clamping drive component is connected to the first clamping arm and the second clamping arm through the transmission assembly to drive the first clamping arm and the second clamping arm to move synchronously towards or away from each other.

[0012] In one embodiment, both the first clamping arm and the second clamping arm are configured as semi-circular, and the first clamping arm and the second clamping arm are symmetrically arranged.

[0013] The beneficial effects of this utility model are:

[0014] The aforementioned rebar bundling device utilizes an alignment mechanism to push the ends of the rebars, which is more efficient than manual pushing. Furthermore, the clamping mechanism can clamp the rebar bundles before bundling. Then, the first bundling mechanism performs the first bundling of the rebars, increasing the friction between the rebars and ensuring a consistent moving speed. The bundled rebars then run on a roller conveyor to the second bundling mechanism, where the clamping mechanism clamps the rebar bundles again. The second bundling mechanism performs the second bundling of the rebar bundles, completing the bundling process. The final bundled rebars exhibit high neatness and tightness.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0025] refer to Figures 1-4As shown in the figure, an embodiment of this utility model proposes a rebar bundling device, including a first bundling mechanism 3, a second bundling mechanism 4, a clamping mechanism 5, an alignment mechanism 2, and a roller conveyor 1. The roller conveyor 1 is used to transport the rebar bundles. The roller conveyor 1 is prior art and can be any conveying mechanism with the function of transporting rebars 6 used in existing rebar bundling machines, which will not be elaborated here. The first bundling mechanism 3 and the second bundling mechanism 4 are arranged at intervals along the conveying direction of the roller conveyor 1. The alignment mechanism 2 is arranged upstream of the first bundling mechanism 3 and is used to push the ends of the rebars 6 to align the rebars 6 used to form the rebar bundles. At least the first bundling mechanism 3 has clamping mechanisms 5 arranged at both the front and rear of it for clamping the rebar bundles. It should be noted that "front" refers to upstream and "rear" refers to downstream.

[0026] The above-mentioned rebar bundling device uses the alignment mechanism 2 to push the end of the rebar 6, which is more efficient than manual pushing. Moreover, the clamping mechanism 5 can clamp the rebar 6 before bundling. Then, the first bundling mechanism 3 performs the first bundling of the rebar 6, which increases the friction between the rebars and keeps the moving speed of the rebars 6 consistent. After bundling, the rebar bundle runs on the roller conveyor 1 to the second bundling mechanism 4. The clamping mechanism 5 clamps the rebar bundle again, and the second bundling mechanism 4 performs the second bundling of the rebar bundle to complete the bundling work. Finally, the completed rebar bundle has high neatness and tightness.

[0027] In some embodiments, the alignment mechanism 2 is located at the upstream end of the roller conveyor 1 and includes an alignment drive and a pusher plate. The alignment drive is used to push the pusher plate to move along the conveying direction of the roller conveyor 1, thereby aligning the reinforcing bars 6. Exemplarily, the alignment drive is a hydraulic cylinder. To reduce the power required by the alignment drive and thus reduce the manufacturing cost of the reinforcing bar bundling device, the reinforcing bar bundles can enter the roller conveyor 1 in batches, and the alignment mechanism 2 aligns the reinforcing bar bundles in batches.

[0028] Based on this, in order to avoid interference between the reinforcing bars 6 and the influence of the alignment mechanism 2 on the feeding of the reinforcing bars 6, such as Figure 3 and Figure 4 As shown, the first binding mechanism 3 is a sword-piercing binding machine, which can open and close from the side. The distance between the first binding mechanism 3 and the second binding mechanism 4 is greater than the length of the reinforcing bar 6. The reinforcing bar 6 enters the first binding mechanism 3 from the side and then moves towards the second binding mechanism 4 via the roller conveyor 1. Taking a bundle of reinforcing bars including 300 reinforcing bars 6 as an example, it can be divided into 6 batches, with 50 reinforcing bars 6 in each batch being put onto the roller conveyor 1, that is, the alignment mechanism 2 simultaneously pushes 50 reinforcing bars 6.

[0029] The second binding mechanism 4 can be either a piercing binding machine or a ring binding machine. In the current embodiment, the second binding mechanism 4 uses a ring punching machine, and the reinforcing bar bundle is inserted into the ring binding machine along the length of the reinforcing bar 6. Both piercing punching machines and ring punching machines are existing technologies and will not be described in detail here.

[0030] refer to Figure 3 As shown, in the current embodiment, the clamping mechanism 5 includes a first clamping arm 51, a second clamping arm 52, a clamping seat 53, a first clamping drive member 54, and a second clamping drive member 55. Both the first clamping arm 51 and the second clamping arm 52 are rotatably mounted on the clamping seat 53. The first clamping drive member 54 is connected to the first clamping arm 51 and drives the first clamping arm 51 to rotate. The second clamping drive member 55 is connected to the second clamping arm 52 and drives the second clamping arm 52 to rotate. Both the first clamping arm 51 and the second clamping arm 52 are semi-circular and symmetrically arranged. The first clamping drive member 54 and the second clamping drive member 55 can be hydraulic cylinders or pneumatic cylinders.

[0031] Specifically, in order to improve the clamping ability, at least two clamping mechanisms 5 are provided at the front and rear of both the first binding mechanism 3 and the second binding mechanism 4.

[0032] In other embodiments, the clamping mechanism 5 also includes a first clamping arm, a second clamping arm, and a clamping seat. The clamping mechanism also includes a clamping drive component and a transmission assembly. The first and second clamping arms are still rotatably mounted on the clamping seat, and both the first and second clamping arms are configured as semi-circular, symmetrically arranged. The first clamping arm is rotatably connected to the clamping seat via a first rotating shaft, and the second clamping arm is rotatably connected to the clamping seat via a second rotating shaft. The clamping drive component is connected to the first and second clamping arms via the transmission assembly to drive the first and second clamping arms to move synchronously towards or away from each other.

[0033] For example, the transmission assembly includes a first transmission gear and a second transmission gear, the first transmission gear and the second transmission gear meshing, and the first transmission gear is sleeved on a first rotating shaft, and the second transmission gear is sleeved on a second rotating shaft.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
