[0002] Welded mesh (rebar welded mesh) is a steel mesh with longitudinal and transverse steel bars arranged at a certain interval and at right angles to each other, and all intersections are welded together. It is mainly used in bridges, water conservancy projects, highways, and other projects that require concrete pouring. Traditional welded mesh production relies on machines to straighten and cut the steel bars, and then manually arrange and weld them. This method consumes a lot of labor costs, has extremely low production efficiency, and the quality of the welded mesh is difficult to guarantee.

[0003] In order to improve the production efficiency of welding mesh, various steel bar welding mesh machines and steel bar welding mesh production lines have emerged, which can complete the welding requirements of various welding meshes with different wire diameters and different mesh sizes with high quality. Although there are many types of steel bar welding mesh machines, the welding principles and methods are basically the same. They all arrange the straightened and sheared longitudinal bars and transport them between the upper electrode and the lower electrode of the welding machine by various means, and then drop the transverse bars to the predetermined position. The upper electrode and the lower electrode cooperate to weld the transverse bars to the intersections of each longitudinal bar.

[0004] However, in the existing steel bar welded mesh production line, the spacing between adjacent longitudinal bars is difficult to adjust, and it is not suitable for the production of welded meshes of various specifications, especially different longitudinal bar distances.

[0033] refer to Figure 1-Figure 8 As shown, in the embodiment of the present invention, a spacing adjustment mechanism 10 and a longitudinal reinforcement feeding device are proposed. The longitudinal reinforcement feeding device includes a plurality of clamps 20 and the above-mentioned spacing adjustment mechanism 10. The clamps 20 are used to clamp the longitudinal reinforcement 31. The spacing adjustment mechanism 10 can adjust the distance between the clamps 20. The spacing adjustment mechanism 10 includes a support beam 11, a positioning member 12, a moving assembly 13 and an adjusting assembly 14, wherein the positioning member 12 and the moving assembly 13 are both arranged on the support beam 11, and the positioning member 12 is fixed relative to the support beam 11, and the output end of the moving assembly 13 can be relative to the support beam 11 along a first direction ( Figure 1The support beam 11 is movable in the X-axis direction, and multiple adjustment components 14 are arranged on the support beam 11 at intervals along the first direction. The adjustment components 14 include a first state in which the adjustment components are connected to the positioning member 12 and separated from the moving component 13, and a second state in which the adjustment components are connected to the moving component 13 and separated from the positioning member 12. When the adjustment components 14 are in the first state, they are fixed relative to the support beam 11. When the adjustment components 14 are in the second state, they can move along the first direction together with the output end of the moving component 13. Multiple clamps 20 are installed on the multiple adjustment components 14 one by one to adjust the spacing driven by the moving component 13.

[0034] The adjustment component 14 in the above-mentioned spacing adjustment mechanism 10 includes a first state in which it is connected to the positioning member 12 and separated from the moving component 13, and a second state in which it is connected to the moving component 13 and separated from the positioning member 12. When the adjustment component 14 is in the first state, the distance between adjacent adjustment components 14 remains unchanged. When the adjustment component 14 is in the second state, it can move along the first direction with the moving component 13, thereby realizing a change in the distance between adjacent adjustment components 14, and further realizing a change in the distance between the clamps 20 installed on the adjustment component 14.

[0035] It can be understood that the above-mentioned spacing adjustment mechanism 10 can also be applied to other devices that require spacing adjustment, such as in a welding machine for welding longitudinal reinforcements 31 and transverse reinforcements 32. Multiple welding heads are arranged one by one on the adjustment component 14, so that the spacing between multiple welding heads can be adjusted.

[0036] In this embodiment, the positioning member 12 includes a positioning rack, and the teeth on the positioning rack are distributed along a first direction. The moving component 13 includes a moving rack 131. The moving rack 131 can move along the first direction relative to the support beam 11. The teeth on the moving rack 131 are also distributed along the first direction and are spaced apart from the positioning rack along the second direction. The teeth on the moving rack 131 are arranged opposite to the teeth on the positioning rack. The adjusting component 14 includes an adjusting tooth block 141 and a first driving member 142. The adjusting tooth block 141 is arranged between the moving rack 131 and the positioning rack, and teeth are arranged on the surfaces of the adjusting tooth block 141 facing the moving rack 131 and the positioning rack. The first driving member 142 is movably arranged on the support beam 11 along the first direction and is connected to the adjusting tooth block 141. The first driving member 142 is configured to drive the adjusting tooth block 141 to move along the second direction so that the adjusting tooth block 141 engages with the moving rack 131 or the positioning rack, thereby realizing connection with the positioning member 12 or the moving component 13. The second direction is perpendicular to the first direction.

[0037] When the adjusting tooth block 141 is engaged with the fixed rack, since the fixed rack is fixed on the support beam 11, the distance between the adjusting tooth blocks 141 engaged with the fixed rack remains unchanged, and the distance between the clamping jaws 20 on the adjusting tooth block 141 is stable; when the adjusting tooth block 141 is engaged with the movable rack 131, the adjusting tooth block 141 can move along the first direction with the movable rack 131, so as to realize the change of the distance between the clamping jaws 20 on adjacent adjusting tooth blocks 141, and the distance between the adjusting components 14 is adjusted by using the movable rack 131, and the adjustable distance is not limited. The adjustments between different adjusting components 14 do not interfere with each other. The position of one clamping jaw 20 can be adjusted, and the positions of multiple clamping jaws 20 can be adjusted, so that the adjustment stroke of different adjusting components 14 can be set according to actual needs.

[0038] Exemplarily, the second direction is the vertical direction. Figure 1 In the Z-axis direction, the first direction is the horizontal direction.

[0039] In other embodiments, the adjusting component 14 and the positioning member 12 as well as the adjusting component 14 and the moving component 13 may be connected by magnetic connection, which will not be described in detail here.

[0040] refer to Figure 1 and Figure 2 As shown, the support beam 11 extends along the first direction, the clamping jaw 20 includes a clamping side plate 23, and the clamping jaw 20 is movably connected to the support beam 11 by sliding the clamping side plate 23 set on the support beam 11. The adjustment component 14 also includes an adjustment fixing seat 15 fixedly connected to the clamping side plate 23, and the fixed end of the first driving member 142 is fixed on the adjustment fixing seat 15. The output end of the first driving member 142 is slidably connected to the adjustment fixing seat 15 along the second direction to improve the stability of the adjustment tooth block 141 connected to the output end of the first driving member 142 moving along the second direction.

[0041] Specifically, the first driving member 142 is arranged on a side of the fixed rack facing away from the adjusting gear block 141. In order to prevent the fixed rack from affecting the movement of the first driving member 142 in the first direction, the adjusting assembly 14 further includes a gear block mounting plate 143 slidably connected to the adjusting fixed seat 15 in the second direction. The gear block mounting plate 143 is mounted on the output end of the first driving member 142, that is, the output end of the first driving member 142 is slidably connected to the adjusting fixed seat 15 through the gear block mounting plate 143. The gear block mounting plate 143 is set in a U shape, one end of which is connected to the output end of the first driving member 142, and the other end extends between the fixed rack and the movable rack 131 and is fixedly connected to the adjusting gear block 141. Exemplarily, the first driving member 142 is a cylinder.

[0042] refer to Figure 5 and Figure 6As shown, in order to improve the stability of the moving rack 131 when it moves along the first direction, the moving rack 131 is also slidably connected to the support beam 11. Exemplarily, the support beam 11 is provided with a first slide rail 16 extending along the first direction, and the moving rack 131 is provided with a first slider 17 slidably connected to the first slide rail 16. The moving rack 131 and the support beam 11 are slidably matched through the first slide rail 16 and the first slider 17 that are slidably matched.

[0043] It is understandable that the movement of the mobile rack 131 along the first direction can be achieved by manual drive or mechanical drive. In order to improve the degree of automation and realize automated production, the mobile assembly 13 also includes a second drive member 132, which is connected to the mobile rack 131 to drive the mobile rack 131 to move along the first direction.

[0044] Exemplarily, the second driving member 132 is a worm screw lift to improve the accuracy of adjusting the distance between the clamping jaws 20 .

[0045] refer to Figure 2 As shown, the adjustment component 14 is also slidably arranged on the support beam 11, and a second slide rail 19 extending along the first direction is arranged on the support beam 11. A second slider 18 slidably matched with the second slide rail 19 is arranged on the clamping side plate 23. The adjustment component 14 is slidably connected by the second slide rail 19 and the second slider 18 that slidably cooperate with each other.

[0046] refer to Figure 7 and Figure 8 As shown, the clamping jaw 20 also includes a third driving member (not shown in the figure), a first clamping block 21 and a second clamping block 22. The first clamping block 21 and the second clamping block 22 are both hinged on the clamping side plate 23. The third driving member is connected to the first end of the first clamping block 21 and the first end of the second clamping block 22. The third driving member is configured to drive the second end of the first clamping block 21 and the second end of the second clamping block 22 (that is, the first clamping block 21 and the second clamping block 22 are respectively away from the end of the third driving member) to move towards or away from each other to clamp or release the longitudinal reinforcement 31.

[0047] Optionally, the first end of the first clamping block 21 and the first end of the second clamping block 22 are respectively provided with a first guide groove 211 and a second guide groove 221 in the shape of a strip, and the output end of the third driving member can penetrate into the first guide groove 211 and the second guide groove 221 and move in the vertical direction. Under the guiding action of the first guide groove 211 and the second guide groove 221, the second end of the first clamping block 21 and the second end of the second clamping block 22 move toward or away from each other.

[0048] Furthermore, a third guide groove 231 extending in the vertical direction is provided on the clamping side plate 23, and the output end of the third driving member is movably provided in the third guide groove 231, and the third guide groove 231 is used to guide the moving direction of the output end of the third driving member. Exemplarily, the third driving member is a cylinder.

[0049] In order to increase the clamping force of the clamping jaw 20 on the longitudinal rib 31, a plurality of first clamping portions 212 and second clamping portions 222 are respectively arranged at intervals along the third direction at the second end of the first clamping block 21 and the second end of the second clamping block 22. The first clamping portions 212 and the second clamping portions 222 are staggered in the third direction, and the third direction is perpendicular to the first direction and perpendicular or parallel to the second direction.
