Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "center", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0039] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] When the two working gears 100 are installed, as shown in Figure 2 shown, it is difficult to ensure that the tooth tip of one of them and the center of the tooth groove of the other are on the same vertical line. When the tooth tip of one of them and the center of the tooth groove of the other are not on the same vertical line, as shown in Figure 2 shown, at this time, the wave crests of the pressed corrugated wires are not in the same horizontal plane, resulting in warping and deformation of the woven wire mesh, seriously affecting the product quality of the wire mesh. When the tooth tip of one of the two working gears 100 and the center of the tooth groove of the other are not on the same vertical line, as shown in Figure 2 point a and point b in are not on the same vertical line, it is necessary to remove the working gear 100 and the driving mechanism and reinstall and adjust them until the tooth tip of one of them and the center of the tooth groove of the other are on the same vertical line. As shown in Figure 3 shown, point a and point b are on the same vertical line. The means of the prior art are cumbersome to operate and affect the production efficiency.

[0041] In view of the above problems, an embodiment of the present utility model provides a driving mechanism and a wire rolling machine. When the driving device stops, the first input shaft 1 can be rotated independently, so as to ensure the same bending degree of the corrugated wire and improve the product quality.

[0042] The following combines Figures 4 - 9 to elaborate on the technical solution provided by the present utility model in more detail.

[0043] Embodiment 1:

[0044] See Figures 4 - 9 As shown, Figure 4 , Figure 5 is the A perspective view in Figure 6 , Figure 8 , Figure 9 is the B perspective view in Figure 6 .

[0045] The driving mechanism provided by the present utility model includes a first input shaft 1, a second input shaft 4, and a first output shaft 3 and a second output shaft 6 respectively used for drivingly connecting with two working gears 100 for pressing corrugated wires. Among them: the first output shaft 3 is drivingly connected with the first input shaft 1, the second output shaft 6 is drivingly connected with the second input shaft 4, and the first output shaft 3 and the second output shaft 6 can output the power after deceleration; the driving device is drivingly connected with the second input shaft 4 and is used for driving the second input shaft 4 to rotate; a moving gear 11 is sleeved on the first input shaft 1, an input gear is fixed on the second input shaft 4, and the moving gear 11 can axially move along the first input shaft 1 under the action of an external force, so that the moving gear 11 and the input gear are in a meshing state or a separated state; when in the meshing state, the first input shaft 1 and the second input shaft 4 can rotate synchronously and reversely, and when in the separated state, the first output shaft 3 can rotate independently compared with the second output shaft 6.

[0046] Among them, the driving device can be a motor or the like. The driving device drives the first input shaft 1 to rotate. When in the meshing state, the first input shaft 1 and the second input shaft 4 rotate synchronously and reversely. Since the first output shaft 3 is drivingly connected with the first input shaft 1 and the second output shaft 6 is drivingly connected with the second input shaft 4, therefore, the first output shaft 3 and the second output shaft 6 output the power after deceleration, and the first output shaft 3 and the second output shaft 6 can drive the two working gears 100 to rotate through belt drive, chain drive or the like.

[0047] For the drive mechanism of this embodiment, the movable gear 11 can move along the axial direction of the first input shaft 1. When the movable gear 11 is in the meshed state with the input gear, under the drive of the driving device, the first input shaft 1 and the second input shaft 4 rotate synchronously and in opposite directions. The first output shaft 3 and the second output shaft 6 reduce the power and output it, so that the two working gears 100 for pressing the corrugated wire rotate synchronously and in opposite directions. When the movable gear 11 is in the separated state from the input gear, power cannot be transmitted between the first input shaft 1 and the second output shaft 6. When the driving device stops, the first input shaft 1 can rotate alone. At this time, the first output shaft 3 can rotate alone.

[0048] With such a setting, among the two working gears 100 for pressing the corrugated wire, one of the working gears 100 can rotate alone, so that the tooth tip of one working gear 100 and the center of the tooth groove of the other working gear 100 are located on the same vertical line, thereby ensuring the same bending degree of the corrugated wire and improving the product quality.

[0049] As an optional implementation manner, referring to Figure 4 、 Figure 5 and Figure 8 、 Figure 9 As shown, a guide rail portion 13 is fixed on the first input shaft 1. The guide rail portion 13 is arranged along the axial direction of the first input shaft 1. The inner ring of the movable gear 11 is provided with a spline, and the spline extends into the guide rail portion 13, so that the movable gear 11 can move along the guide rail portion 13.

[0050] The guide rail portion 13 includes a spline groove. The spline on the inner ring of the movable gear 11 extends into the spline groove of the guide rail portion 13. By manually or driving the movable gear 11 through a driving structure, the movable gear 11 can be moved along the guide rail portion 13.

[0051] As an optional implementation manner, referring to Figure 4 and Figure 5 As shown, the drive mechanism of this embodiment further includes a lever assembly. The movable gear 11 is fixedly connected with a limit groove 12, and at least part of the lever assembly extends into the limit groove 12. Pressing the lever assembly can drive the movable gear 11 and the limit groove 12 to move along the axial direction of the first input shaft 1.

[0052] By the operator pressing the lever assembly, the movable gear 11 and the limit groove 12 can be moved along the axial direction of the first input shaft 1 to realize the separation of the movable gear 11 from the input gear. And when the lever assembly is not manually pressed, at least part of the lever assembly extends into the limit groove 12, which can prevent axial movement when the movable gear 11 meshes with the input gear and ensure the stability of the drive structure.

[0053] As an optional implementation manner, referring to Figure 4 and Figure 5As shown, the lever assembly of this embodiment includes a transverse moving rod 72, a hand-held rod 71 and a connecting portion 73, wherein: the connecting portion 73 is fixedly connected to the transverse moving rod 72, and the connecting portion 73 is clamped and fixed in the limiting groove 12; the hand-held rod 71 is rotatably connected to the outer wall of the casing through the shaft portion 74, and one end of the hand-held rod 71 is rotatably connected to the transverse moving rod 72. By pressing the other end of the hand-held rod 71, the hand-held rod 71 can rotate around the shaft portion 74 as the axis, thereby pulling the transverse moving rod 72 and the connecting portion 73 to move axially along the first input shaft 1, thereby driving the moving gear 11 to move axially along the first input shaft 1.

[0054] The connecting portion 73 may be a connecting rod structure or a connecting sleeve structure. The connecting portion 73 is inserted into the limiting groove 12 to drive the limiting groove 12 and the moving gear 11 to move axially along the first input shaft 1 .

[0055] See also Figure 4 As shown, when the lever assembly is not pressed, the moving gear 11 is in meshing with the input gear, and the connecting portion 73 can limit the axial movement of the moving gear 11. Figure 5 As shown, when the hand-held lever 71 is pressed, the hand-held lever 71 rotates around the rotating shaft portion 74, and the end of the hand-held lever 71 tilts, pulling the lateral moving rod 72 and the connecting portion 73 to move along the axial direction of the first input shaft 1, see Figure 5 As shown, the moving gear 11 is thereby separated from the input gear.

[0056] At this time, by keeping the handle 71 pressed and rotating the first input shaft 1, the first input shaft 1 can rotate independently compared with the second input shaft 4, thereby rotating the first output shaft 3 independently compared with the second output shaft 6, and further rotating one of the working gears 100 independently.

[0057] As an alternative embodiment, see Figure 4 and Figure 5 As shown, the first input shaft 1 is fixedly connected to a rotating wheel 8, and the rotating wheel 8 is located outside the casing and is rotatably connected to the casing.

[0058] The rotating wheel 8 can be rotated manually to rotate the first input shaft 1, thereby realizing independent power output of the first output shaft 3.

[0059] As an alternative embodiment, see Figures 4 - 7 As shown, Figure 4 , Figure 5 for Figure 6In the A perspective, the driving mechanism further includes a first transmission shaft 2 and a second transmission shaft 5, where: a first output gear is fixed on the first output shaft 3, and the first output gear is in meshing transmission with the first transmission shaft 2 (the first output gear is in meshing with a gear or a lead screw structure on the first transmission shaft 2). A first driving gear is fixed on the first transmission shaft 2, and the first driving gear is in meshing transmission with the first input shaft 1, for outputting the power after deceleration; a second output gear is fixed on the second output shaft 6, and the second output gear is in meshing transmission with the second transmission shaft 5 (the second output gear is in meshing with a gear or a lead screw structure on the second transmission shaft 5). A second driving gear is fixed on the second transmission shaft 5, and the second driving gear is in meshing transmission with the second input shaft 4, for outputting the power after deceleration.

[0060] The outer diameters of the moving gear 11, the first driving gear, and the first output gear increase in sequence.

[0061] The outer diameters of the input gear, the second driving gear, and the second output gear increase in sequence.

[0062] In the above structure, the power of the first input shaft 1 is decelerated and output through the first driving gear and the first output gear. The power of the second input shaft 4 is decelerated and output through the second driving gear and the second output gear. An appropriate reduction ratio can be set to realize the decelerated rotation of the working gear 100.

[0063] As an optional implementation manner, the first transmission shaft 2 and the second transmission shaft 5 are symmetrically arranged with respect to the horizontal plane, and the first output shaft 3 and the second output shaft 6 are symmetrically arranged with respect to the horizontal plane.

[0064] The above structure can realize the synchronous reverse rotation of the two working gears 100, so as to press the corrugated wire.

[0065] Embodiment 2:

[0066] This embodiment provides a wire rolling machine, including the above driving mechanism. The first output shaft 3 and the second output shaft 6 are respectively in transmission connection with two working gears 100 for pressing corrugated wires.

[0067] In the wire rolling machine of this embodiment, the driving device drives the first input shaft 1 to rotate, uses this driving mechanism to realize the decelerated output of the power, and among the two working gears 100 for pressing corrugated wires, one of the working gears 100 can rotate independently, so that the tooth top of one of the working gears 100 and the center of the tooth groove of the other working gear 100 are located on the same vertical line, thereby ensuring the same bending degree of the corrugated wire and improving the product quality.
