Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, and in particular to an adjustable rebar cage winding device. Background Technology

[0002] Reinforcing cage reinforcement is an important method of steel reinforcement configuration in concrete structures, typically used to improve the tensile, compressive, and shear strength of concrete. The main function of the reinforcement is to enhance the overall stability of the cage, preventing displacement of the reinforcing bars during concrete pouring or subsequent construction, thereby ensuring the safety and reliability of the structure.

[0003] Existing rebar cage winding devices are typically used in automated or semi-automated rebar cage fabrication processes. These devices mechanically assist in configuring the rebar cage winding, improving production efficiency while ensuring the quality and consistency of the rebar cages. Existing automated winding machines utilize motor drives and sensor control to achieve automatic winding; however, the equipment is precision-driven, requires high investment, and incurs high maintenance costs. Furthermore, existing rebar cage winding devices can only wind rebar cages of one specification; when changing specifications, precise adjustments to the device are required, extending the winding cycle. Therefore, a rebar winding device capable of easily and quickly winding rebar cages of various specifications is needed. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide an adjustable rebar cage winding device.

[0005] The technical solution of this utility model is: an adjustable rebar cage winding device, including a rebar coil and a rebar cage; the device also includes idler rollers, a drive motor, and a movable unwinding support; the rebar coil is placed on the movable unwinding support; two idler rollers are arranged side by side, and bearing seats are provided at both ends of the idler rollers; the two idler rollers support the rebar cage; the drive motor drives the idler rollers to rotate through a chain; a sprocket is provided at the end of each idler roller, and the sprocket is connected to the drive motor through a chain; the movable unwinding support is placed on one side of the idler rollers, and a guide rail is provided at the bottom of the movable unwinding support, and the movable unwinding support moves along the guide rail.

[0006] The movable unwinding support unwinds the reinforcing bars. One end of the unwound reinforcing bar is fixed to the reinforcing cage. When the rollers rotate, the reinforcing cage also rotates, and the unwound reinforcing bars can be wound onto the reinforcing cage. At the same time, the movable unwinding support moves along the guide rail to make the reinforcing bars evenly wound onto the entire reinforcing cage.

[0007] Preferably, the idler roller comprises a plurality of rollers connected end-to-end, with universal joints connecting the ends of the rollers. The number of rollers can be adjusted according to the required length of the reinforcing cage to be wound, improving the adaptability and practicality of the device.

[0008] Preferably, the guide rail is parallel to the idler roller. Moving the movable unwinding support parallel to the guide rail and idler roller allows for a stable match between the unwinding speed of the movable unwinding support and the rotational speed of the idler roller, improving the uniformity of the reinforcing bar winding in the steel cage.

[0009] Preferably, a support base is provided in the middle of the idler roller, the support base is fixed to the ground, and two support wheels are provided on the support base, with the two support wheels in contact with the outer wall of the idler roller. When the length of the idler roller is too long, because the roller is connected by a universal joint, the roller near the middle will sag due to lack of support, which will seriously affect the normal use of the device. Using a support base to support the middle of the roller improves the stability of the device.

[0010] Furthermore, the roller is provided with outer ribs on its outer side, which are spirally arranged on the outer wall of the roller. The outer ribs can increase the friction between the roller and the reinforcing cage, preventing slippage and thus avoiding the problem of the reinforcing cage being unable to rotate.

[0011] Preferably, the idler rollers include idler roller A and idler roller B, and the sprockets include sprocket A and two sprockets B; sprocket A and one sprocket B are coaxially disposed at the end of idler roller A; the other sprocket B is disposed at the end of idler roller B; the two sprockets B are connected by a chain, and chain A is connected to the output end of the drive motor. Chain drive has high transmission accuracy, long transmission distance, simple structure, and strong reliability; and it can keep the rotation direction and rotation speed of the two idler rollers consistent.

[0012] Preferably, the movable unwinding support includes a chassis, a rotating frame, track wheels, and a straightening head; the track wheels are mounted on the chassis and cooperate with guide rails; the rotating frame is rotatably connected to the chassis; the straightening head is fixed to the chassis and points towards the idler rollers. The rebar coil is placed on the rotating frame of the movable unwinding support, with one end of the rebar coil passing through the straightening head, enabling preliminary processing of the unwound rebar and improving the uniformity of the wound rebar cage.

[0013] The beneficial effects of this utility model are as follows: The adjustable rebar cage winding device of this utility model has the following advantages:

[0014] 1. The idler roller is equipped with several rollers connected by universal joints. This not only transmits the torque provided by the drive motor, but also prevents uneven ground from reducing the coaxiality of the rollers, ensuring the stable and normal operation of the device and improving the winding accuracy. At the same time, the connection of several rollers can handle the winding of steel cages of various lengths.

[0015] 2. The guide rail and the idler roller are parallel to each other, so that the movable unwinding support can move parallel to the guide rail and the idler roller. This allows the unwinding speed of the movable unwinding support to be stably matched with the rotation speed of the idler roller, thereby improving the uniformity of the reinforcing bar winding in the steel cage.

[0025] Example 1: See Figure 1-6 An adjustable rebar cage winding device includes a rebar coil and a rebar cage; the device also includes idler rollers, a drive motor 15, and a movable unwinding support 3; the rebar coil is mounted on the movable unwinding support 3; two idler rollers are arranged side by side, with bearing seats 13 at both ends of the idler rollers; the two idler rollers support the rebar cage; the drive motor 15 drives the idler rollers to rotate via a chain; a sprocket is provided at the end of each idler roller, and the sprocket is connected to the drive motor 15 via a chain; the movable unwinding support 3 is located on one side of the idler rollers, and a guide rail 31 is provided at the bottom of the movable unwinding support 3, along which the movable unwinding support 3 moves. The guide rail 31 is arranged side by side with the idler rollers, and the length of the guide rail 31 is much greater than the length of the idler rollers.

[0026] The movable unwinding support 3 unwinds the reinforcing bars. One end of the unwound reinforcing bar is fixed to the reinforcing cage. When the roller rotates, the reinforcing cage also rotates, and the unwound reinforcing bar can be wound onto the reinforcing cage. At the same time, the movable unwinding support 3 moves along the guide rail 31 to make the reinforcing bar evenly wound onto the entire reinforcing cage.

[0027] The idler roller comprises several rollers 11 connected end to end, with universal joints 12 connecting the ends of the rollers 11. The number of rollers 11 can be adjusted according to the required length of the reinforcing cage to be wound, improving the adaptability and practicality of the device.

[0028] The guide rail 31 is parallel to the idler roller. The movable unwinding support 3 moves parallel to the idler roller along the guide rail 31, which enables the unwinding speed of the movable unwinding support 3 to be stably matched with the rotation speed of the idler roller, thereby improving the uniformity of the reinforcing bar winding in the steel cage.

[0029] A support base 14 is provided in the middle of the idler roller, and the support base 14 is fixed to the ground. Two support wheels 141 are provided on the support base 14, and the two support wheels 141 are in contact with the outer wall of the idler roller. When the length of the idler roller is too long, since the roller 11 is connected by a universal joint 12, the roller 11 near the middle will deflect due to lack of support, which will seriously affect the normal use of the device. The support base 14 is used to support the middle of the roller 11, thereby improving the stability of the device.

[0030] The outer side of the roller 11 is provided with an outer rib 111, which is spirally arranged on the outer wall of the roller 11. The outer rib 111 can improve the friction between the roller 11 and the reinforcing cage, and avoid slippage, which would prevent the reinforcing cage from rotating.

[0031] The idler rollers include idler roller A and idler roller B, and the sprockets include sprocket A 24 and two sprockets B 25. Sprocket A 24 and one sprocket B 25 are coaxially disposed at the end of idler roller A; the other sprocket B 25 is disposed at the end of idler roller B; the two sprockets B 25 are connected by a chain, and chain A is connected to the output end of drive motor 15. Chain drive offers high transmission accuracy, long transmission distance, simple structure, and strong reliability; it also ensures that the rotation direction and speed of the two idler rollers remain consistent.

[0032] The chain is equipped with a protective shell 21 to prevent foreign objects from entering the chain drive system and affecting the normal operation of the device.

[0033] The movable unwinding support 3 includes a chassis 32, a rotating frame 33, track wheels 35, and a straightening head 34. The track wheels 35 are mounted on the chassis 32 and cooperate with the guide rail 31. The rotating frame 33 is rotatably connected to the chassis 32. The straightening head 34 is fixed to the chassis 32 and points towards the idler roller. The rebar coil is placed on the rotating frame 33 of the movable unwinding support 3, and one end of the rebar coil passes through the straightening head 34, which can perform preliminary treatment on the unwound rebar and improve the uniformity of the wound rebar cage.

[0034] The working process of this embodiment includes the following steps:

[0035] ① Adjust the number of rollers 11 according to the required length of the reinforcing cage;

[0036] ② Place the steel cage to be wound onto the two idler rollers;

[0037] ③ Drive the movable unwinding support 3 to move to the end of the steel cage;

[0038] ④ Unwind the steel bar coil and weld one end of the unwound steel bar to the outer side of the end of the steel cage.

[0039] ⑤ Start the drive motor 15 to make the idler roller drive the steel cage to rotate slowly in the predetermined direction;

[0040] ⑥ Drive the movable unwinding support 3 to move along the guide rail 31 toward the head end of the steel cage, and the moving speed is matched with the rotation speed of the steel cage;

[0041] ⑦ After the winding is completed, the joints of the steel cage are welded, and the steel bars connecting the steel cage and the steel coil are cut off. The winding of the steel cage is then completed.

[0042] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the distance between the two roller bearing seats 13 can be adjusted, which can accommodate more sizes of steel cages and improve the practicality of the device.
