[0033] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-14 As shown, a metal mesh rolling and welding device of the present invention includes a frame 1, a limit frame 2, a winding needle 3, a welding head 4, a telescopic cylinder 5, a sealing cylinder 6 and a limit plate 7, which is used to first wind the sheet or strip metal mesh into a cylindrical shape, and then weld and fix the outer end of the metal mesh.

[0035] The frame 1 is the main frame structure of the coiling welding device, the limit frame 2 is slidably set on the frame 1, the winding needle 3 is rotatably set on the frame 1, and is driven by a driving device such as a reducer. A winding cavity 201 is opened inside the limit frame 2, and a through groove 202 connected to the winding cavity 201 is opened on the peripheral side of the limit frame 2. The winding needle 3 is located in the winding cavity 201, and a limit groove 301 is opened on the peripheral side of the winding needle 3. When one end of the metal mesh is inserted into the limit groove 301 along the through groove 202 and the winding cavity 201, the metal mesh can be driven to be wound on the peripheral side of the winding needle 3 by rotating the winding needle 3 to form a cylindrical structure.

[0036] The cylindrical metal mesh is prone to loosening during the transfer process. To solve this problem, a welding head 4 is fixedly installed on the frame 1. After the metal mesh is wound into a cylindrical shape by the winding needle 3, the output end of the welding head 4 passes through the through groove 202 and moves into the winding cavity 201 to weld and fix the outer end of the cylindrical metal mesh.

[0037] It is preferred that the limiting groove 301 penetrates the circumferential side of the winding needle 3 so that one end of the metal mesh can penetrate the winding needle 3, thereby avoiding the problem of separation of the metal mesh and the winding needle 3 when the winding needle 3 is rotated, thereby improving the winding quality of the metal mesh; in order to allow the metal mesh that has been rolled and welded to be separated from the winding needle 3, the limiting groove 301 must also penetrate to the end of the winding needle 3 away from the frame 1, so that the metal mesh is separated from the winding needle 3 along the axial direction of the winding needle 3. Similarly, the winding cavity 201 and the through groove 202 both penetrate to the end of the limiting frame 2 away from the frame 1.

[0038] The opening direction of the through groove 202 is parallel to the horizontal plane. Figure 3 As shown, the winding needle 3 rotates in the counterclockwise direction, the top side in the through groove 202 is the front end face, the position where the inner wall of the winding cavity 201 intersects with the front end face is the first node, the bottom side in the through groove 202 is the rear end face, the position where the inner wall of the winding cavity 201 intersects with the rear end face is the second node, the minimum distance from the circumference of the winding needle 3 to the first node is a, and the distances from the circumference of the winding needle 3 to other positions on the inner wall of the winding cavity 201 are all greater than a. When the metal mesh is wound into a cylindrical shape, the outer end of the metal mesh only rubs against the position on the inner wall of the winding cavity 201 located at the upper end of the through groove 202, but does not rub against other positions on the inner wall of the winding cavity 201, which is beneficial to prolonging the service life of the winding device; at the same time, during the winding process of the metal mesh, only the position on the inner wall of the winding cavity 201 located at the upper end of the through groove 202 exerts pressure on the metal mesh, which is also beneficial to improving the winding tightness of the metal mesh and avoiding the problem of loose winding.

[0039] like Figure 3As shown in the figure, the outer diameter of the coiling needle 3 is 2r, and the distance from the circumferential side of the coiling needle 3 to the lower position inside the coiling cavity 201 is e. Then a < e, and the outer diameter of the metal wire mesh after coiling and forming is 2a + 2r. After the metal wire mesh is coiled and welded, the bottom side of the metal wire mesh is spaced from the lower part inside the coiling cavity 201, as Fig.13 shown. After the metal wire mesh is coiled and welded, when the limiting frame 2 is moved to the left to separate the coiled and welded metal wire mesh from the coiling needle 3, the metal wire mesh will move downward and abut against the lower part inside the coiling cavity 201. At this time, the coiling needle 3 will not coincide with the hole in the middle of the metal wire mesh. If the limiting frame 2 is moved to the right, the coiling needle 3 can push the metal wire mesh out of the coiling cavity 201, realizing the automatic blanking of the metal wire mesh and improving the batch processing efficiency of the metal wire mesh.

[0040] As Figure 3 shown, the radian corresponding to the through groove 202 on the circumferential side of the limiting frame 2 is β. The smaller the value of β, the more beneficial it is to ensure the coiling and forming effect of the metal wire mesh. β should be less than π. In order to facilitate the insertion of the metal wire mesh into the through groove 202, the value of β cannot be too small, and it is preferably 40 - 70 degrees.

[0041] As Figure 3 shown, the minimum distance from the circumferential side of the coiling needle 3 to the second node is b, the distance from the circumferential side of the coiling needle 3 to the position opposite to the first node inside the coiling cavity 201 is c, and the inner diameter of the coiling cavity 201 is 2R. Then 2R = a + c + 2r, and c > b > a. After the metal wire mesh is coiled and welded, in order to facilitate the blanking of the metal wire mesh, the metal wire mesh should be rotated so that the circumferential side of the metal wire mesh is spaced from the inner wall of the coiling cavity 201. It is preferably that the difference between b and a is greater than the thickness of the sheet metal wire mesh, that is, the difference between e and a is greater than the thickness of the sheet metal wire mesh, so that the metal wire mesh separated from the coiling needle 3 and abutting against the lower part inside the coiling cavity 201 can be better held by the coiling needle 3, so that the metal wire mesh can be better separated from the coiling cavity 201.

[0042] As Figure 4 shown, the coiling needle 3 includes a rotating shaft 31 and two limiting rods 32. The rotating shaft 31 is rotatably arranged on the frame 1 and the limiting frame 2. The limiting rods 32 are detachably fixed on the rotating shaft 31. Different specifications of limiting rods 32 can be replaced according to the size of the metal wire mesh to be processed. The limiting rods 32 are located inside the coiling cavity 201, and the two limiting rods 32 are spaced apart, and the interval between the two limiting rods 32 is the limiting groove 301.

[0043] As Figure 7As shown, the limiting rod 32 includes a fixed rod 321, a movable rod 322, an anchor rod 323 and a spring 324. The fixed rod 321 is detachably fixed to the rotating shaft 31. The movable rod 322 is located behind the fixed rod 321 along the rotating direction of the rotating shaft 31. One end of the anchor rod 323 is fixedly set on the movable rod 322, and the other end penetrates and is slidably set on the fixed rod 321. The spring 324 is sleeved on the anchor rod 323, and its two ends are respectively against the anchor rod 323 and the fixed rod 321. Figure 3 As shown, in the natural state, the movable rod 322 is in contact with the fixed rod 321 in the same limiting rod 32, and the interval between the two limiting rods 32 is the largest. Figure 5 As shown, when the rotating shaft 31 rotates in the counterclockwise direction, the spring 324 will shrink, so that the movable rod 322 moves away from the fixed rod 321 in the same limiting rod 32, so that the interval between the two limiting rods 32 is reduced, so that the movable rod 322 and the fixed rod 321 that are not in the same limiting rod 32 can clamp the metal mesh, thereby preventing the metal mesh from escaping from the limiting groove 301 when the winding needle 3 rotates; in order to make the interval between the two limiting rods 32 change evenly, it is preferred that the two limiting rods 32 are symmetrically arranged about the axis center of the rotating shaft 31.

[0044] When the rotating shaft 31 rotates, the minimum distance between the two limiting rods 32 is zero, that is, the movable rod 322 can abut against the fixed rod 321 which is not in the same limiting rod 32, so that the limiting rod 32 can adapt to metal meshes of different thicknesses.

[0045] like Fig. 9 As shown, a plurality of tooth grooves 302 are provided on one end of the movable rod 322, so that the end of the movable rod 322 that abuts against the metal mesh is uneven. Since the surface of the metal mesh is hollow, when the movable rod 322 abuts against the metal mesh, the uneven structure can provide a better abutting effect for the metal mesh, thereby ensuring the winding quality of the metal mesh; of course, the tooth groove 302 can also run through the entire movable rod 322 for processing and convenient coordination with the fixed rod 321.

[0046] The limiting rod 32 further includes a plurality of tooth claws 325, which are integrally formed on the fixing rod 321. The plurality of tooth claws 325 correspond to the plurality of tooth grooves 302 one by one, and the tooth claws 325 are slidably disposed in the corresponding tooth grooves 302. Figure 8 As shown, in the natural state, the end of the claw 325 away from the fixed rod 321 is flush with the movable rod 322, and the claw 325 is used to fill the uneven structure on the movable rod 322, that is, the two form a planar structure to avoid obstruction of the metal mesh when it extends into the limiting groove 301.

[0047] like Figure 8As shown, when the rotating shaft 31 stops rotating, the movable rod 322 will abut against the fixed rod 321 which is in the same limiting rod 32. In order to prevent the two from approaching and clamping the metal mesh, it is necessary to chamfer one end of the movable rod 322 which is close to the fixed rod 321 which is in the same limiting rod 32.

[0048] One end of the tooth claw 325 away from the fixed rod 321 is flush with the end of the fixed rod 321 away from the tooth claw 325. In a natural state, the two ends of the limiting rod 32 are located in the same plane, and the end faces of the two limiting rods 32 are parallel, so that the interval between the two limiting rods 32 is uniform and flat, which is convenient for the insertion of the metal mesh.

[0049] The cross section of the limiting rod 32 is in the shape of an arc, and the center of the cross section of the limiting rod 32 is located on the axis of the rotating shaft 31. Figure 5 As shown, when the rotating shaft 31 is rotated, the length of the circumference of the limiting rod 32 increases, and the circumference of the central hole of the cylindrical metal mesh is equal to twice the sum of the length of the circumference of the limiting rod 32 and the distance between the ends of the two limiting rods 32. Figure 3 As shown, when the rotating shaft 31 stops rotating, the length of the side of the limit rod 32 decreases, and the distance between the ends of the two limit rods 32 increases. However, the decrease in the length of the side of the limit rod 32 is greater than the increase in the distance between the ends of the two limit rods 32, so that a gap appears between the metal mesh and the winding needle 3 after the welding is completed, making it easier to separate the metal mesh and the winding needle 3.

[0050] like Fig.10 As shown, m is the center of the cross section of the limiting rod 32, and n is the axis of the winding cavity 201. At this time, the limiting frame 2 and the winding needle 3 are in the first state, and the axis of the winding cavity 201 is set between the end faces of the two limiting rods 32. At this time, the distance from the axis of the winding cavity 201 to the end face of the limiting rod 32 located below is less than half the thickness of the metal mesh. When the metal mesh is inserted into the limiting groove 301, the distance between the axis of the winding cavity 201 and the lower side of the metal mesh is less than the distance between the winding cavity 201 and the lower side of the metal mesh. The distance between the axis of the winding cavity 201 and the upper side of the metal mesh; when one end of the metal mesh extends into the limiting groove 301 and abuts against the inner wall of the winding cavity 201, the angle between the metal mesh and the upper inner wall of the winding cavity 201 is smaller than the angle between the metal mesh and the lower inner wall of the winding cavity 201. When the metal mesh continues to be extended into the metal mesh, the inner end of the metal mesh will move downward along the inner wall of the winding cavity 201. At this time, the winding needle 3 is rotated counterclockwise to better wind the metal mesh.

[0051] like Fig.11As shown, m is the center of the cross section of the limiting rod 32, and n is the axis of the winding cavity 201. At this time, the limiting frame 2 and the winding needle 3 are in the second state, and the axis of the winding cavity 201 is arranged on the side of the end face of the limiting rod 32 located below away from the limiting rod 32 located above. When the metal mesh is inserted into the limiting groove 301, the distance between the axis of the winding cavity 201 and the lower side of the metal mesh is smaller than the distance between the axis of the winding cavity 201 and the upper side of the metal mesh; when one end of the metal mesh extends into the limiting groove 301 and abuts against the inner wall of the winding cavity 201, the inner end of the metal mesh will also move downward along the inner wall of the winding cavity 201. At this time, let the winding needle 3 rotate counterclockwise, which can also better wind the metal mesh.

[0052] like Fig.12 As shown, the telescopic cylinder 5 is fixedly arranged on the frame 1, and its output end is fixedly connected to the limit frame 2. The limit frame 2 can be driven to move by the extension and retraction of the output end of the telescopic cylinder 5 to realize the unloading operation of the metal mesh.

[0053] like Fig.13 As shown, the blocking cylinder 6 is fixedly arranged on the frame 1, and the limit plate 7 is fixedly arranged on the output end of the blocking cylinder 6. When the metal mesh is inserted into the winding chamber 201, the blocking cylinder 6 is used to drive the limit plate 7 to move to the end of the limit frame 2 away from the frame 1, thereby preventing the metal mesh from axially moving during the winding process.

[0054] like Fig.13 As shown, the length of the limit frame 2 is less than the distance between the limit plate 7 and the frame 1, and the length of the winding needle 3 is equal to the distance between the limit plate 7 and the frame 1. By controlling the telescopic cylinder 5, the distance between the limit frame 2 and the limit plate 7 can be adjusted, so that the winding chamber 201 can adapt to metal meshes of different specifications.

[0055] The method of using a metal mesh coiling and welding device of the present invention is as follows: S1, use the telescopic cylinder 5 to drive the limit frame 2 to slide, so that the distance between the side away from the limit plate 7 in the winding chamber 201 and the limit plate 7 is equal to the width of the metal mesh, so that the coiling and welding device can adapt to the specifications of the metal mesh to be processed.

[0056] S2, using the blocking cylinder 6 to drive the limiting plate 7 to move to the end of the winding needle 3 away from the frame 1, so as to partially or completely block the winding chamber 201.

[0057] S3, extending one end of the metal mesh into the through slot 202 and the limiting slot 301 in sequence, and allowing the end of the metal mesh to abut against the inner wall of the winding cavity 201.

[0058] S4, rotating the winding needle 3, and after the metal mesh is rolled up by the winding needle 3, the rolled metal mesh is continuously rotated at least one circle to make the rolled metal mesh tighter, until the outer end of the metal mesh is located in the through groove 202.

[0059] S5, moving the welding head 4 into the through slot 202, and welding and fixing the outer end of the metal mesh.

[0060] S6, rotate the winding needle 3 so that the outer end of the winding needle 3 is located at the bottom of the winding cavity 201, move the welding head 4 out of the through slot 202, and move the limiting plate 7 to the top of the limiting frame 2 to move the metal mesh out of the obstruction of the winding cavity 201.

[0061] S7, first use the telescopic cylinder 5 to drive the limit frame 2 away from the frame 1, so that the rolled metal mesh can be separated from the winding needle 3 and abutted at the bottom of the winding chamber 201, and then use the telescopic cylinder 5 to drive the limit frame 2 close to the frame 1, so that the winding needle 3 abuts against the end of the metal mesh, so that the rolled metal mesh can be separated from the winding chamber 201, and the metal mesh after coiling and welding can be unloaded.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
