[0029] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the overall structure of an embodiment of the steel bar binding equipment of the present application. Figure 2 yes Figure 1 The partial structural diagram of the steel bar tying device in the embodiment, the steel bar tying device in the embodiment includes a lifting mechanism 10, an adjustment component 30 and a tying gun 60, wherein the lifting mechanism 10 can be fixed on a bracket or other structure. The lifting mechanism 10 is configured with a moving component 20 that can be moved along a first direction to Figure 1 The Y direction in the figure is the first direction. Optionally, the lifting mechanism 10 in this embodiment is a linear driving mechanism, including but not limited to a cylinder, an oil cylinder, an electric push rod, etc. Taking the lead screw as an example here, the lifting mechanism 10 includes a guide seat 101, a motor 102, and a lead screw 103. The motor 102 is installed on the guide seat 101, and the lead screw 103 is rotatably set on the guide seat 101 and is transmission-connected to the motor 102. The lead screw 103 is threadedly connected to the moving component 20.

[0030] See also Figures 3 to 5 , Figure 3 yes Figure 1 The schematic diagram of the structural decomposition of the adjustment component in the embodiment, Figure 4 yes Figure 3 A schematic diagram of the structural decomposition of the adjustment component from another perspective in the embodiment, Figure 5 yes Figure 3Schematic diagram of the structure when the adjustment assembly is assembled in the embodiment. The adjustment assembly 30 is rotatably arranged on the moving assembly 20, and the adjustment assembly 30 can drive the tying gun 60 to rotate in at least one direction relative to the moving assembly 20. Specifically, in the present embodiment, the adjustment assembly 30 may include a rotating member 301, and the rotating member 301 is rotatably arranged on the moving assembly 20 through a first rotating shaft 303, and the axial direction of the first rotating shaft 303 can be in any direction, for example, the axial direction of the first rotating shaft 303 is parallel to the first direction, or the axial direction of the first rotating shaft 303 is perpendicular to the first direction. The moving assembly 20 may include a moving seat 201, which is threadedly connected to the screw rod 103, and a rotating mounting plate 302 is fixedly connected to the moving seat 201; in some scenarios, a bearing seat 309 is fixedly set on the rotating mounting plate 302, and the first rotating shaft 303 is rotatably set in the bearing seat 309 through a rotating bearing 304, and the first rotating shaft 303 is fixedly connected to the rotating member 301; in some scenarios, the first rotating shaft 303 is fixedly connected to the rotating mounting plate 302, and the rotating member 301 is rotatably connected to the first rotating shaft 303 through the rotating bearing 304.

[0031] The tying gun 60 is detachably fixedly connected to the rotating part 301 by welding / riveting / bolting. The tying gun 60 can automatically feed, tie and cut the wire. The specific structure of the tying gun 60 is within the scope of understanding of those skilled in the art and will not be described in detail here.

[0032] See also Figure 7 , Figure 7 yes Figure 1 The working diagram of the steel bar binding equipment in the embodiment adopts the above scheme. The binding gun 60 moves along the first direction with the moving component 20 under the drive of the lifting mechanism 10 and extends into the binding area of ​​the steel mesh 40. When the gun nozzle of the binding gun 60 touches the steel bar, it can automatically rotate around the first rotating axis 303 to adapt to the position of the intersection of the steel bars, so that the binding gun 60 is aimed at the intersection of the steel bars.

[0033] In some embodiments, in order to further improve the flexibility of the tying gun 60, the tying gun 60 is rotatably disposed on the rotating member 301 via a second rotating shaft 306, and the axial direction of the second rotating shaft 306 is perpendicular to the first direction, that is, the axial direction of the second rotating shaft 306 is located at Figure 1 In the plane with the Y direction as the normal.

[0034] See also Figure 3 and Figure 5The rotating member 301 includes a rotating seat 3011 and a rotating base plate 3012. A swing bearing 307 is rotatably arranged inside the rotating seat 3011. The rotating base plate 3012 is detachably fixedly connected to the rotating seat 3011 by bolts, so as to facilitate the installation of the swing bearing 307 and limit the swing bearing 307. The second rotating shaft 306 and the extension line of the first rotating shaft 303 are perpendicular to and intersect with each other. One end of the second rotating shaft 306 is connected to the swing bearing 307, and the other end passes through the rotating base plate 3012 and is fixedly provided with a swing member 305. The swing member 305 is detachably fixedly connected to the tying gun 60 by bolts.

[0035] Of course, the tying gun 60 can also be connected to the rotating member 301 by other rotational connection methods, for example, a through hole is opened in the rotating member 301, one end of the second rotating shaft 306 is fixedly connected to the tying gun 60, and the other end of the second rotating shaft 306 passes through the through hole and two limit plates are fixedly arranged along its axial direction. The two limit plates are respectively tightly attached to both sides of the rotating member 301 to prevent the axial translation of the rotating member 301 relative to the second rotating shaft 306. There is no requirement for the specific shape of the limit plate, which can be circular, square, triangular, etc., so as to limit the axial movement of the rotating member 301 relative to the second rotating shaft 306.

[0036] In this way, the tying gun 60 has rotational freedom in the first direction and in the axial direction perpendicular to the first direction, so that the tying gun 60 can rotate around the first rotation axis 303 after contacting the steel bar, and can also swing around the second rotation axis 306, thereby realizing multi-degree-of-freedom adjustment of the steel bar tying equipment, and further improving the fault tolerance for the arrangement of the steel mesh 40 or the lowering position of the tying gun 60, avoiding the situation where tying failure is caused by uneven placement of steel bars on site, deformation of steel bars, inaccurate positioning of the tying gun 60, etc.

[0037] In some embodiments, the moving assembly 20 further includes a slider 202 slidably disposed on the moving seat 201 along a first direction, an elastic member is disposed between the slider 202 and the moving seat 201 , and the slider 202 is fixedly connected to the rotating mounting plate 302 .

[0038] See also Figure 2The movable seat 201 comprises an upper base plate 2011, a lower base plate 2012, a connecting plate 2013 and a screw connection 2014. The screw connection 2014 is threadedly connected to the screw rod 103. The upper base plate 2011 and the lower base plate 2012 are fixedly connected through the connecting plate 2013 and the screw connection 2014. A guide column 204 is fixedly arranged between the upper base plate 2011 and the lower base plate 2012 along a first direction. The slider 202 is slidably sleeved on the outside of the guide column 204. An elastic member is arranged between the slider 202 and the movable seat 201. The elastic member can be a spring, a bellows, a spring, etc. Here, a spring is taken as an example. The spring 203 is sleeved between the upper base plate 2011 and the slider 202. In order to ensure the stability of the device, two groups of guide columns 204, springs 203 and sliders 202 are arranged and symmetrically installed on the movable seat 201. The two ends of the spring 203 can be fixedly connected to the upper substrate 2011 and the slider 202, or one end of the spring 203 can be fixedly connected to the upper substrate 2011 and the other end can be movably abutted against the slider 202, or one end of the spring 203 can be fixedly connected to the slider 202 and the other end can be movably abutted against the upper substrate 2011, or the two ends of the spring 203 can be movably abutted against the upper substrate 2011 and the slider 202. In addition, a buffer 205 is also provided between the slider 202 and the lower substrate 2012, and the buffer 205 is a buffer structure well known to those skilled in the art, such as a rubber block, pearl cotton, etc.

[0039] By adopting the above scheme, after the lifting mechanism 10 drives the moving component 20 to move a certain distance along the first direction, since the slider 202 has a certain degree of freedom of movement along the first direction, it can cooperate with the tying gun 60 to adaptively adjust its own angle and inclination when it contacts the steel bars; at the same time, in the case of inconsistent steel bar diameters, the moving seat 201 only needs to move a certain distance each time to allow the tying gun 60 to automatically adapt to the position of the steel bars, thereby avoiding frequent adjustments to the moving stroke of the moving component 20 due to different diameters of the tied steel bars.

[0040] For further information, see Figure 1 and Figure 2 , a proximity switch 501 is fixedly arranged on the lifting mechanism 10, and a sensor sheet 502 is fixedly arranged on the upper base plate 2011. After the lifting mechanism 10 is started, the upper sensor sheet 502 moves along the first direction to find the position of the proximity switch 501, confirms the origin, and then drives the tying gun 60 and the moving assembly 20 to move a certain distance and extend into the steel bar tying area for tying after reaching the origin. It should be understood that the sensor sheet 502 can be arranged at other positions of the moving seat 201, such as the connecting plate 2013 or the lower base plate 2012, so as not to move relative to the screw connection 2014. The sensor sheet 502 can also be a part of the moving seat 201.

[0041] In some embodiments, a rotational reset assembly 312 is provided between the rotating member 301 and the slider 202 so that the rotating member 301 always has a tendency to return to its initial position relative to the slider 202; a swinging reset assembly 313 is provided between the tying gun 60 and the rotating member 301 so that the tying gun 60 always has a tendency to return to its initial position relative to the rotating member 301.

One end of the two first tension springs 3121 passes through the two through holes of the first connecting member 314 to connect with the first connecting member 314, and the other end passes through the first mounting holes 3151 of the two second connecting members 315 to connect with the second connecting member 315. At least two second mounting holes 3152 are also provided on one side of each second connecting member 315 away from the first connecting member 314, and two through holes are provided on both sides of the radial direction of the second rotating shaft 306 on the swinging member 305. One end of the two second tension springs 3131 passes through the two through holes of the swinging member 305 to connect with the swinging member 305, and the other end passes through the two second mounting holes 3152 of any second connecting member 315 to connect with the second connecting member 315.

For example, the rotational reset component 312 includes a torsion spring, which is sleeved on the first rotating shaft 303, and the two legs of the torsion spring are respectively clamped with the first rotating shaft 303 and the rotating mounting seat. The specific installation method of the torsion spring is familiar to those skilled in the art and will not be elaborated here.

[0044] It should be understood that the rotation reset assembly 312 and the swing reset assembly 313 do not affect each other, so the rotation reset assembly 312 and the swing reset assembly 313 can be set separately, for example, the rotation reset assembly 312 is only set between the rotating member 301 and the slider 202, or the swing reset assembly 313 is only set between the tying gun 60 and the rotating member 301.
