Description

Technical Field

[0001] This invention relates to the field of welded wire mesh processing technology, and in particular to a spacing adjustment mechanism, a longitudinal rib feeding device, and a welded wire mesh production line. Background Technology

[0002] Welded wire mesh (reinforced concrete mesh) is a steel mesh sheet in which longitudinal and transverse reinforcing bars are arranged at certain intervals and perpendicular to each other, with all intersections welded together. It is mainly used in projects such as bridges, water conservancy projects, and highways that require concrete pouring. Traditional welded wire mesh production relies on machines to straighten and cut the reinforcing bars, followed by manual arrangement and welding. This method consumes a lot of labor costs, has extremely low production efficiency, and makes it difficult to guarantee the quality of the welded wire mesh.

[0003] To improve the production efficiency of welded wire mesh, various types of steel wire mesh welding machines and production lines have emerged, capable of completing the welding requirements of various wire meshes with different wire diameters and mesh counts with high quality. Although there are many types of steel wire mesh welding machines, the welding principles and welding methods are basically the same. They all involve arranging the straightened and sheared longitudinal bars and transporting them between the upper and lower electrodes of the welding machine through various means, then placing the transverse bars into predetermined positions, and welding the intersections of the transverse bars and the various longitudinal bars together through the combined action of the upper and lower electrodes.

[0004] However, in existing welded wire mesh production lines, the spacing between adjacent longitudinal bars is difficult to adjust, making it unsuitable for producing welded wire meshes of various specifications, especially those with different longitudinal bar spacing. Summary of the Invention

[0005] The purpose of this invention is to provide a spacing adjustment device, a longitudinal rib feeding device, and a welded wire mesh production line to solve the problem of difficulty in adjusting the spacing between longitudinal ribs during welded wire mesh production.

A plurality of adjusting components are spaced apart on the support beam along the first direction. Each adjusting component includes a first state connected to the positioning element but separated from the moving component, and a second state connected to the moving component but separated from the positioning element. When the adjusting component is in the first state, it is fixed relative to the support beam. When the adjusting component is in the second state, it is movable along the first direction along with the output end of the moving component.

[0008] Optionally, the positioning element includes a positioning rack, the moving component includes a moving rack, the positioning rack and the moving rack are spaced apart along a second direction, the moving rack is movable relative to the support beam along a first direction, the adjusting component includes an adjusting block and a first driving member, the adjusting block is disposed between the moving rack and the positioning rack, the first driving member is movably disposed on the support beam along the first direction and connected to the adjusting block, the first driving member is configured to drive the adjusting block to move along the second direction so that the adjusting block meshes with the moving rack or the positioning rack, the second direction being perpendicular to the first direction.

[0009] Optionally, the movable rack is slidably connected to the support beam.

[0010] Optionally, the first driving member is slidably connected to the support beam.

[0011] Optionally, the moving component further includes a second driving member connected to the moving rack to drive the moving rack to move along the first direction.

[0033] refer to Figures 1-8 As shown, an embodiment of the present invention proposes a spacing adjustment mechanism 10 and a longitudinal rib feeding device. The longitudinal rib feeding device includes a plurality of grippers 20 and the aforementioned spacing adjustment mechanism 10. The grippers 20 are used to clamp the longitudinal ribs 31, and the spacing adjustment mechanism 10 can adjust the distance between the grippers 20. The spacing adjustment mechanism 10 includes a support beam 11, a positioning member 12, a moving component 13, and an adjusting component 14. The positioning member 12 and the moving component 13 are both disposed on the support beam 11, and the positioning member 12 is fixed relative to the support beam 11. The output end of the moving component 13 can move relative to the support beam 11 along a first direction ( Figure 1The adjustment components 14 are arranged at intervals on the support beam 11 along the first direction (X-axis direction). The adjustment components 14 include a first state connected to the positioning member 12 and separated from the moving component 13, and a second state connected to the moving component 13 and separated from the positioning member 12. When the adjustment component 14 is in the first state, it is fixed relative to the support beam 11. When the adjustment component 14 is in the second state, it can move along the first direction together with the output end of the moving component 13. Multiple grippers 20 are installed on the multiple adjustment components 14 one by one to realize the adjustment of the spacing under the drive of the moving component 13.

[0034] The adjustment component 14 in the aforementioned spacing adjustment mechanism 10 includes a first state connected to the positioning member 12 and separated from the moving component 13, and a second state 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 the change in the distance between adjacent adjustment components 14, and thus realizing the change in the distance between the grippers 20 installed on the adjustment component 14.

[0035] It is understood that the above-mentioned spacing adjustment mechanism 10 can also be applied to other devices that require spacing adjustment, such as welding machines used for welding longitudinal ribs 31 and transverse ribs 32. Multiple welding heads are arranged one-to-one on the adjustment component 14, which can realize the adjustment of the spacing between multiple welding heads.

[0036] In this embodiment, the positioning member 12 includes a positioning rack with teeth distributed along a first direction. The moving component 13 includes a moving rack 131, which can move relative to the support beam 11 along the first direction. The teeth on the moving rack 131 are also distributed along the first direction and spaced apart from the positioning rack along a second direction. The teeth on the moving rack 131 are opposite to the teeth on the positioning rack. The adjusting component 14 includes an adjusting block 141 and a first driving member 142. The adjusting block 141 is disposed between the moving rack 131 and the positioning rack, and teeth are provided on the surfaces of the adjusting block 141 facing the moving rack 131 and the positioning rack. The first driving member 142 is movably disposed on the support beam 11 along the first direction and connected to the adjusting block 141. The first driving member 142 is configured to drive the adjusting block 141 to move along the second direction so that the adjusting block 141 meshes with the moving rack 131 or the positioning rack, thereby achieving 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 meshes with the fixed rack, the distance between the adjusting tooth blocks 141 meshing with the fixed rack remains unchanged because the fixed rack is fixed on the support beam 11, and the distance between the grippers 20 on the adjusting tooth block 141 is stable. When the adjusting tooth block 141 meshes with the moving rack 131, the adjusting tooth block 141 can move along the first direction with the moving rack 131, thereby realizing the change of the distance between the grippers 20 on adjacent adjusting tooth blocks 141. Moreover, the distance between the adjusting components 14 can be adjusted by using the moving rack 131, and the distance can be adjusted without limitation. The adjustment between different adjusting components 14 does not interfere with each other. The position of one gripper 20 can be adjusted, or the position of multiple grippers 20 can be adjusted, so that the adjustment stroke of different adjusting components 14 can be set according to actual needs.

[0038] For example, the second direction is the vertical direction, i.e. Figure 1 The Z-axis direction is the central axis, with the first direction being the horizontal direction.

[0039] In other embodiments, the adjustment component 14 and the positioning component 12, and the adjustment component 14 and the moving component 13 can be connected by magnetic attraction, which will not be described in detail here.

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

[0041] Specifically, the first driving member 142 is disposed on the side of the fixed rack facing away from the adjusting rack 141. 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 rack mounting plate 143 that is slidably connected to the adjusting fixed seat 15 in the second direction. The rack 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 rack mounting plate 143. The rack mounting plate 143 is U-shaped, with one end connected to the output end of the first driving member 142, and the other end extending between the fixed rack and the moving rack 131 and fixedly connected to the adjusting rack 141. For example, the first driving member 142 is a cylinder.

[0042] refer to Figure 5 and Figure 6As shown, 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. For example, 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 achieve a sliding engagement through the sliding engagement of the first slide rail 16 and the first slider 17.

[0043] It is understood that the movement of the movable rack 131 along the first direction can be achieved manually or mechanically. To improve the level of automation and achieve automated production, the movable component 13 also includes a second drive member 132, which is connected to the movable rack 131 to drive the movable rack 131 to move along the first direction.

[0044] For example, the second drive unit 132 employs a screw jack to improve the accuracy of adjusting the spacing between the grippers 20.

[0045] refer to Figure 2 As shown, the adjustment component 14 is also slidably mounted on the support beam 11. The support beam 11 is provided with a second slide rail 19 extending in the first direction. The clamping side plate 23 is provided with a second slider 18 that slides with the second slide rail 19. The adjustment component 14 is slidably connected through the slidingly engaged second slide rail 19 and second slider 18.

[0046] refer to Figure 7 and Figure 8 As shown, the gripper 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 to 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 (i.e. the ends of the first clamping block 21 and the second clamping block 22 that are away from the third driving member) to move closer to each other or further away from each other, so as to clamp or release the longitudinal rib 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 strip-shaped first guide groove 211 and a second guide groove 221. The output end of the third drive member can pass through the first guide groove 211 and the second guide groove 221 and move in the vertical direction. Under the guidance 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 closer to each other or further away from each other.

[0048] Furthermore, the clamping side plate 23 is provided with a third guide groove 231 extending in the vertical direction. The output end of the third driving member is movably disposed within the third guide groove 231, which guides the movement direction of the output end of the third driving member. For example, the third driving member is a cylinder.

[0049] To enhance the clamping force of the gripper 20 on the longitudinal rib 31, multiple first clamping portions 212 and second clamping portions 222 are respectively provided at intervals along a third direction from the second end of the first clamping block 21 to the second end of the second clamping block 22. The first clamping portions 212 and second clamping portions 222 are staggered along the third direction, which is perpendicular to the first direction and either perpendicular to or parallel to the second direction. For example, the third direction is... Figure 1 In the Y-axis direction.
