The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0025] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0026] See also Figures 1 to 6 In an embodiment of the utility model, a steel bar cutting device for laying a steel mesh includes a workbench 1, a supporting frame 2, a support frame 13, a cutting mechanism, an adjustment mechanism, a balancing component, a conveying device, a one-way transmission member, and a moving member.

[0027] The details are as follows, including:

[0028] See also Figure 1 , Figure 3 , Figure 4 The workbench 1 is fixedly mounted on a support frame 2 on the workbench 1, on which a cutting mechanism is mounted, and further comprises a support frame 13 mounted on the workbench 1, on which an adjustment mechanism is mounted, and further comprises a balancing component mounted on the adjustment mechanism, and when the cutting mechanism performs a cutting operation, the steel bar is squeezed by the balancing component and can always maintain a balanced state;

[0029] A conveying device is installed on the workbench 1, and the cutting mechanism is connected to the conveying device via a one-way transmission member;

[0030] A moving part is installed on the workbench 1 and connects the conveying device and the balancing component. When the conveying device is working, the moving part pushes the balancing component to move relative to the adjusting mechanism.

[0031] In detail, in this embodiment, the steel bar cutting device for steel mesh laying described in the utility model is adopted. When in use, the gap between the adjusting mechanism and the conveying device is controlled to ensure that steel bars of different sizes can be clamped and conveyed. The steel bars are conveyed to the top of the cutting structure by the conveying device to be cut. When the cutting structure moves downward, the conveying device stops conveying. Only when the cutting structure moves upward, the conveying device is driven to work by the one-way transmission member to achieve equidistant cutting of the steel bars. When the steel bars are cut, the cutting structure exerts downward pressure on the steel bars. Under the action of the balancing component, one end of the steel bars is prevented from tilting during cutting, and the steel bars can always remain in a horizontal state. The conveying device drives the moving part to work, so as to drive the balancing component to move relative to the adjusting mechanism, so as to keep the steel bars in a balanced state during the cutting process.

[0032] See also Figure 1 , Figure 3 The cutting mechanism includes a first electric telescopic rod 3 installed on the support frame 2, a blade 4 is arranged on the movable end of the first electric telescopic rod 3, and a ratchet plate 5 is fixedly connected to one end of the blade 4.

[0033] The conveying device comprises a receiving plate 9 fixedly mounted on the workbench 1 , and a roller 10 is rotatably mounted on the receiving plate 9 .

[0034] The one-way transmission member includes a first transmission shaft 7 rotatably mounted on the supporting bracket 2, and a ratchet 6 adapted to the ratchet plate 5 is provided on the first transmission shaft 7. The first transmission shaft 7 is rotatably connected to a second transmission shaft 11 rotatably mounted on the receiving plate 9 through a first bevel gear set 8, and the second transmission shaft 11 is rotatably connected to the rotating roller 10 through a belt 12.

[0035] When the above-mentioned blade 4 moves upward, the ratchet plate 5 and the ratchet wheel 6 engage to make the ratchet wheel 6 rotate, thereby realizing the rotation of the first transmission shaft 7. When the first transmission shaft 7 rotates, it drives the second transmission shaft 11 to rotate through the first bevel gear set 8, and the second transmission shaft 11 drives the roller 10 to rotate through the belt 12 to achieve the transmission requirements.

[0036] See also Figure 4 The adjustment mechanism includes a second electric telescopic rod 14 installed on the support frame 13, a connecting plate 15 is provided on the movable end of the second electric telescopic rod 14, a cross plate 16 is fixedly connected to one end of the connecting plate 15, the cross plate 16 is slidably installed on the receiving plate 9, a round shaft 17 is movably installed on the cross plate 16, and a limiting groove 18 is formed on the connecting plate 15.

[0037] The gap between the circular shaft 17 and the rotating roller 10 is adjusted according to the size of the steel bar to ensure that steel bars of different sizes can be clamped and transmitted between the rotating roller 10 and the circular shaft 17. After the steel bar is inserted between the circular shaft 17 and the rotating roller 10 and clamped, the first electric telescopic rod 3 is started to work. When the cylinder rod of the first electric telescopic rod 3 is extended, the blade 4 moves down to cut the steel bar. At this time, the rotating roller 10 has not rotated yet. When the cylinder rod of the first electric telescopic rod 3 is retracted, the blade 4 moves up and drives the rotating roller 10 to rotate through the transmission to realize the transmission of the steel bar, and can work continuously to cut into multiple equidistant steel bars.

[0038] See also Figure 4 , Figure 6 The balancing assembly includes a slider 19 slidably mounted on the connecting plate 15 , the slider 19 slidably cooperates with the limiting groove 18 , and a columnar member 21 is movably mounted on the slider 19 .

[0039] The movable part includes a screw rod 25 rotatably mounted on the workbench 1, the screw rod 25 is rotatably connected to the roller 10 through a second bevel gear set 26, a threaded sleeve 24 is threadedly connected to the screw rod 25, a movable plate 22 is fixedly connected to the threaded sleeve 24, and one end of the movable plate 22 away from the threaded sleeve 24 is slidably connected to the slider 19.

[0040] When the above-mentioned roller 10 performs the conveying work on the steel bars, the second bevel gear set 26 drives the screw rod 25 to rotate. When the screw rod 25 rotates, it drives the threaded sleeve 24 to make a linear motion along the axial direction of the screw rod 25. When the threaded sleeve 24 moves, it drives the movable plate 22 to move synchronously, so that as the steel bars are conveyed, the columnar member 21 moves synchronously, so that the steel bars can always maintain a balanced state when cutting.

[0041] Preferably, an embedded groove is formed on the above-mentioned slider 19, and one end of the movable plate 22 is inserted into the embedded groove, wherein a strip limit slider 23 is fixedly provided on the side of the movable plate 22, and the strip limit slider 23 is slidably set in a strip limit slide groove 20 opened in the embedded groove. With the cooperation of the strip limit slide groove 20 and the strip limit slider 23, the slider 19 can be moved relative to the movable plate 22, and the movable plate 22 and the slider 19 will not be separated.
