[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0026] like Figure 1-4 As shown, on one hand, the present invention provides a steel bar transmission mechanism, including at least one first driving wheel 100 and at least one second driving wheel 200 .

[0027] The first driving wheel 100 includes a column 110, a first rotating member 120 and a first movable member 130. One end of the column 110 is fixedly connected to the first rotating member 120, and the other end of the column 110 is movably connected to the first movable member 130. The first movable member 130 can move along the column 110 toward the first rotating member 120.

[0028] The second driving wheel 200 includes a second rotating member 210 and a second moving member 220. The second rotating member 210 is provided with a plurality of slots. The second moving member 220 has a side close to the second rotating member 210 formed with insertion strips corresponding to the plurality of slots. The insertion strips are slidably inserted into the slots.

[0029] The second rotating member 210 and the second moving member 220 , together with the column 110 , the first rotating member 120 and the first moving member 130 , form a transmission port, which is used to transmit steel bars.

[0030] In this embodiment, when the first moving member 130 moves along the column 110 toward the first rotating member 120, the first moving member 130 also pushes the second moving member 220, causing the second moving member 220 to move toward the second rotating member 210. At this time, the width of the transmission port is reduced to limit the steel bars in the transmission port. Then the first rotating member 120 rotates and causes the column 110 to rotate, and the second rotating member 210 rotates and causes the second moving member 220 to rotate. By making the rotation directions of the first rotating member 120 and the second rotating member 210 opposite, the purpose of transmitting the steel bars forward along the transmission port is achieved.

[0031] It should be noted that this solution is mainly used to transport multiple rows of steel bars. By adjusting the diameter of the transmission port, the transmission port can accommodate different numbers of rows of steel bars. During the transmission process, the left and right sides of the row of steel bars are respectively limited and abutted by the first moving member 130 and the first rotating member 120 to ensure stable transmission of the row of steel bars. In addition, the row of steel bars in this solution represents an arrangement of multiple steel bars of the same diameter in parallel and against each other. Based on the teachings of the above embodiments of this application, those skilled in the art can also replace the row of steel bars with square plates without creative work, which should also be included in the scope of protection of this application.

[0032] To specifically illustrate the structural features of the first rotating member 120 .

[0033] Among them, the first rotating member 120 includes a first rotating plate and a first reduction motor; the first rotating plate is fixedly connected to one end of the column 110, and the first rotating plate and the second moving member 220 are surrounded by the column 110, the first rotating member 120 and the first moving member 130 to form a transmission port; the first reduction motor is transmission-connected to the first rotating plate to drive the first rotating plate to rotate (not shown in the accompanying drawings).

[0034] To describe the movement of the first moving member 130 in detail.

[0035] See also Figure 2 The first movable member 130 includes a movable plate 131 and a first driving member 132; the movable plate 131 defines a guide groove that slides with the column 110, and the column 110 can abut against one end of the guide groove away from the column 110, and the first driving member 132 is transmission-connected to the first movable plate 131.

[0036] In this embodiment, the first driving member 132 drives the movable plate 131 to move along the column 110 toward the first rotating member 120. During this process, the column 110 moves along the guide groove. When the column 110 and the end of the guide groove away from the column 110 are against each other, the second rotating member 210 and the second movable member 220 are surrounded by the column 110, the movable plate 131 and the first rotating member 120 to form a transmission port.

[0037] It should be noted that the function of the first driving member 132 is to drive the movable plate 131 to move. Therefore, there are no specific requirements for the structure, size, shape, and quantity of the first driving member 132 in this solution. Any driving structure commonly used in this field that can move the movable plate 131 can be used as the first driving member 132. Preferably, the first driving member 132 is an electric push rod.

[0038] See also Figure 3 The movable plate 131 also has a through-opening, which is connected to the guide groove, and the column 110 can pass through the guide groove and the through-opening in sequence.

[0039] As an optional embodiment, the column 110 is loosely matched with the guide groove and the through-hole. The above arrangement is used to prevent the column 110 from rubbing against the inner walls of the guide groove and the through-hole during rotation.

[0040] Since the movable plate 131 moves along the column 110 toward the first rotating member 120, the movable plate 131 synchronously pushes the second movable member 220, causing the second movable member 220 to move toward the second rotating member 210, and the width of the transmission port is reduced to be used for transmitting a smaller number of continuous rows of steel bars. When a larger number of continuous rows of steel bars needs to be transmitted next time, the positions of the second movable member 220 and the second rotating member 210 are not easy to adjust. Based on this, the structure of the movable plate 131 is further limited.

[0041] See also Figure 4-5 An adsorption member is installed at one end of the movable plate 131 close to the second movable member 220. The adsorption member is used to adsorb with the second movable member 220. In order to reduce the influence of the adsorption member on the rotation of the second movable member 220, the adsorption end of the adsorption member can be adsorbed with the center of the second movable member 220, and the adsorption end of the adsorption member is preferably a magnet.

[0042] For example, a receiving cavity is provided at the center of the side of the second moving member 220, and the end of the moving plate 131 close to the second moving member 220 fits through the receiving cavity, and the adsorption member is rotatably connected to the receiving cavity, wherein the structure of the receiving cavity can be set as a cylindrical cavity (see Figure 4 ), the structure of the accommodating cavity can also be set as a circular cavity (see Figure 5 ), and the diameter of the cylindrical cavity or the circular cavity is larger than the diameter of the end of the moving plate 131 close to the second moving member 220. The above arrangement is used to stably move the second moving member 220 in a direction relative to the second rotating member 210 through the movement of the moving plate 131.

[0043] Optionally, the adsorption member is gap-fitted with the accommodating cavity.

[0044] To specifically describe the structural features of the second rotating member 210 and the second moving member 220 .

[0045] Among them, the second rotating member 210 includes a second rotating plate and a second reduction motor; the second rotating plate and the second moving member 220 are surrounded by the second column 110, the first rotating member 120 and the first moving member 130 to form a transmission port; the second reduction motor is transmission-connected to the second rotating plate to drive the second rotating plate to rotate (not shown in the drawing).

[0046] Furthermore, the second rotating member 210 and the second movable member 220 are both disc structures, the slots are evenly distributed along the outer periphery of the second rotating member 210, and the insertion strips are evenly distributed along the outer periphery of the second movable member 220. The above setting method is used to prevent some steel bars from falling between the second rotating member 210 and the second movable member 220.

[0047] In order to improve the adaptability to the transmission of multiple groups of continuous steel bars with different diameters.

[0048] See also Figure 6 The steel bar transmission mechanism 10 also includes a base 300 and a movable base 400; a slide rail 310 is provided on the base 300; the movable base 400 is slidably connected to the slide rail 310, and the first driving member 132 is installed on the movable base 400, wherein when the movable base 400 slides along the slide rail 310, the height and diameter of the transmission port are adjustable.

[0049] In this embodiment, since the first driving member 132 is installed on the moving base 400, when the moving base 400 slides along the slide rail 310, the column 110, the moving plate 131 and the first rotating member 120 move toward the direction closer to the second rotating member 210 and the second moving member 220 or move away from the second rotating member 210 and the second moving member 220. During this process, the height aperture of the transmission port is reduced or expanded.

[0050] As an optional embodiment, a limit block 320 is detachably connected to the base 300, and the movable seat 400 is formed with a limit groove that cooperates with the limit block 320. When the limit block 320 cooperates with the limit groove, the height and diameter of the transmission port are determined. The significance of the above setting method is to quickly determine the height and diameter of the transmission port corresponding to the row of steel bars.

[0051] like Figure 7 As shown, on the other hand, the present invention further provides a bending machine, comprising the steel bar transmission mechanism 10 and the rotating disk 20 described in any one of the above embodiments.

[0052] The rotating disk 20 has a detachably connected bending block 21, which is arranged on the arc side of the rotating disk 20 and has a bending hole with the same diameter as the transmission port. The bending hole can be aligned with the transmission port.

[0053] In this embodiment, when the row of steel bars passes through the transmission port and the bending hole in sequence, the rotating disk 20 rotates to bend the row of steel bars, and the bending block 21 is detachably connected to the rotating disk 20, so that the bending block 21 with different bending holes can be selected according to the size, diameter and quantity of different row of steel bars.

[0054] As an optional embodiment, the end of the bending hole away from the bending hole is a T-shaped structure, and the rotating disk 20 is provided with a T-shaped sliding groove that cooperates with the T-shaped structure.

[0055] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
