[0002] Steel mesh is also called welded steel mesh, steel welded mesh, steel welded mesh, steel welded mesh, steel mesh, etc. It is a mesh in which longitudinal and transverse bars are arranged at a certain interval and at right angles to each other, and all intersections are welded together.

When the pulling hook 59 contacts the longitudinal reinforcement, it will drive the longitudinal reinforcement and the transverse reinforcement to move together, and stop moving after moving to the left for an appropriate distance.
[0029] The grinding mechanism 12 includes two fixed plates 121 and a driving motor 1211. An upper grinding roller 122 and a lower grinding roller 123 are rotatably installed between the two fixed plates 121. A transmission gear 124 is fixedly installed at the front end of the upper grinding roller 122 and the lower grinding roller 123. An upper pulley 125 fixedly connected to the lower grinding roller 123 is arranged at the front of the transmission gear 124.

Its function is to place the longitudinal ribs to be welded between the guide plate 11 and the inclined seat 8. When the longitudinal ribs come into contact with the upper grinding roller 122 and the lower grinding roller 123, they will be polished by the upper grinding roller 122 and the lower grinding roller 123 rotating in opposite directions, so as to remove impurities and rust on the surface, and the rotating right grinding roller 129 will polish the upper surface of the transverse ribs, so as to remove impurities and rust on the upper surface of the transverse ribs, thereby solving the problem of uneven current conduction caused by rust and impurities, resulting in unstable quality of welding points, incomplete welding or cold welding.
[0030] Among them, the tooth plate 4 is meshed with the long gear 511, the width of the tooth plate 4 is equal to the length of the long gear 511, a slide groove is opened on the right side of the welding mechanism 1, the movable seat 7 is slidably connected with the slide groove, the upper surface of the inclined seat 8 is an inclined surface, the lower surface of the limit plate 10 is parallel to the upper surface of the inclined seat 8, two sets of transmission pulleys 56 are located on the front and rear sides of the fixed seat 51, the top right side surface of the pulling hook 59 is an inclined surface, the driven gear 54 is fixedly connected to the transmission rod 55 on the left, the fixed plate 121 and the driving motor 1211 are both fixedly connected to the base 2, the tensioning wheel 126 is in contact with the driving belt 1213, the two transmission gears 124 are meshed with each other, and the threads on both sides of the double-headed threaded rod 6 are aligned with respect to the center plane between the two movable seats 7. It is said that an appropriate amount of gap is left between the limit plate 10 and the guide plate 11, and a notch is opened on the upper part of the inclined seat 8, whose function is to rotate the double-headed threaded rod 6 so that the front and rear movable seats 7 are located near the outermost steel bars, and the distance between the two movable seats 7 is the length of the longitudinal bars. First, the tensioning wheel 126 is in a state of not tightening the driving belt 1213, and then the adjusting bolt 127 is rotated to drive the moving block 128 and the right grinding roller 129 to move. When the right grinding roller 129 is able to grind the transverse bars, stop rotating the adjusting bolt 127 and fix the tensioning wheel 126 to ensure that the driving belt 1213 is in a taut state, thereby meeting the production of steel meshes of different widths and the welding of transverse bars of different diameters.
[0031] Among them, a working method of a welding mesh machine for reinforcing steel bars comprises the following steps: S1. The distance between the two movable seats 7 is adjusted to be equal to the length of the longitudinal ribs, and the distance between the right grinding roller 129 and the support frame 3 is adjusted to a suitable distance; S2, the upper grinding roller 122 and the lower grinding roller 123 rotating in opposite directions grind the contacting longitudinal ribs, and the rotating right grinding roller 129 grinds the upper surface of the transverse ribs; S3, the longitudinal reinforcement is in contact with the transverse reinforcement and the intersection is located at the welding position, and welding is performed by welding mechanism 1; S4, the pulling mechanism 5 pulls the welded longitudinal and transverse bars to the left by an appropriate distance, and repeats S2 and S3.
[0032] Working principle: Before using the present invention, the required transverse steel bars are evenly placed on the upper side of the support frame 3, and each steel bar is located in the middle of the welding head under the welding mechanism 1. If the number of placed steel bars is less than the number of welding heads, they are placed from the middle to both sides; according to the number of placed steel bars, the double-headed threaded rod 6 is rotated so that the front and rear movable seats 7 are located near the outermost steel bars, and the distance between the two movable seats 7 is the length of the longitudinal bars. The tensioning wheel 126 is first placed in a state where the driving belt 1213 is not compressed, and then the adjusting bolt 127 is rotated to drive the moving block 128 and the right grinding roller 129 to move. When the right grinding roller 129 is able to grind the transverse bars, the adjusting bolt 127 is stopped from rotating, and the tensioning wheel 126 is fixed to ensure that the driving belt 1213 is in a taut state; When the present invention is used, the longitudinal ribs to be welded are placed between the guide plate 11 and the inclined seat 8, the driving motor 1211 works, and the driving pulley 1212 is driven to rotate, and the driving pulley 1212 drives the right pulley 1210, the tensioning pulley 126, and the upper pulley 125 to rotate through the driving belt 1213, and the right pulley 1210 will drive the right grinding roller 129 to rotate, and the right grinding roller 129 will grind the upper surface of the transverse ribs to remove impurities and rust on the upper surface of the transverse ribs, and the upper pulley 125 will drive the lower grinding roller 123 to rotate, and the lower grinding roller 123 will drive the upper grinding roller 122 to rotate through two transmission gears 124, and the upper grinding roller 122 will rotate. The rotation direction between the upper grinding roller 122 and the lower grinding roller 123 is opposite. When the longitudinal reinforcement contacts the upper grinding roller 122 and the lower grinding roller 123, it will be polished by the rotating upper grinding roller 122 and the lower grinding roller 123, thereby removing impurities and rust on the surface and driving the longitudinal reinforcement to move to the left. The longitudinal reinforcement moves to the left and contacts the transverse reinforcement. The magnet 9 has an adsorption effect on the longitudinal reinforcement, preventing the longitudinal reinforcement in contact with the transverse reinforcement from moving, thereby preventing the rear longitudinal reinforcement from sliding off. At this time, the intersection of the longitudinal reinforcement and the transverse reinforcement is exactly located in the middle position of the lower welding head. The upper welding head of the welding mechanism 1 moves downward, thereby welding the intersection of the steel bar and the transverse reinforcement together. The stepper motor 52 works, driving the driving gear 53 to rotate, and the driving gear 53 will drive the driven gear 54 to rotate, and the driven gear 54 will drive the transmission rod 55 on the left to rotate, and through the transmission of the transmission pulley 56 and the transmission belt 57, the long gear 511 rotates, thereby moving to the right along the toothed plate 4, and when the pulling hook 59 contacts the welded longitudinal reinforcement, the pulling hook 59 will squeeze the resetter 510, thereby moving down and passing through the longitudinal reinforcement appropriately, and then the driving gear 53 works in the opposite direction, and the pulling hook 59 will move to the left. When the pulling hook 59 contacts the longitudinal reinforcement, it will drive the longitudinal reinforcement and the transverse reinforcement to move together, and stop moving after moving to the left for an appropriate distance; in the process of moving the longitudinal reinforcement and the transverse reinforcement, since the pulling hook 59 drives the welded longitudinal reinforcement to move to the left, the longitudinal reinforcement inside the limit plate 10 slides and contacts the transverse reinforcement, and under the action of the magnet 9, it will not move with the longitudinal reinforcement, and then repeat the work, thereby welding the longitudinal reinforcement and the transverse reinforcement into a mesh.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
