Description

Technical Field

[0001] The technical solution relates to the technical field of coiled net welding equipment, and particularly refers to a coiled net welder and a control method thereof. Background Art

[0002] During the process of oil and gas drilling and production, in order to prevent sand production in oil and gas wells from causing damage to casings, equipment and production reduction, screens are usually used for sand control.

[0003] For example, Chinese Patent CN202110256197.5 discloses a sand control screen and its application, and Chinese Patent CN200620012375.0 discloses a multi-layer stainless steel wire mesh sand control screen. These screens generally include a central tube (also called an inner sheath or a base tube) inside and a wire mesh (including an inner drainage net and a variable-precision composite sand control layer, or a metal wire mesh sand control sleeve) wrapped outside the central tube.

[0004] However, there are still some deficiencies in the production process of the existing screens: operations such as stacking, feeding, and cutting of the wire mesh need to be completed manually, and the cut wire mesh also needs to be manually wound around the central tube, and then the wire mesh is welded to the central tube by a welding device, resulting in high labor costs, as well as low welding quality and efficiency, which affect the production progress.

A control method for a mesh winding welding machine, for the mesh winding welding machine as described above, includes the following steps: Step S1: By adjusting the sliding seat to move upward on the first guide rod, the first roller and the second roller are separated from each other to open the conveying roller group; stack the multi-layer mesh fabrics in the storage mechanism in alignment, and make the front end of the mesh fabric pass through the first group of conveying roller groups until the second group of conveying roller groups; adjust the position of the first limiting block on the backing plate so that the first limiting block abuts against both sides of the mesh fabric; adjust the sliding seat to move downward on the first guide rod, so that the first roller and the second roller approach each other to close the conveying roller group;

[0017] Step S3: The traction slide moves towards the cutting mechanism, then the traction jaw clamps the front end of the mesh fabric, and the traction slide moves away from the cutting mechanism, thereby pulling out the mesh fabric; during the process of the traction slide pulling the mesh fabric, the conveying roller mechanism transports the mesh fabric to the cutting mechanism, and the spot welding mechanism performs spot welding on the mesh fabric at set intervals; meanwhile, during the process of the traction slide pulling out the mesh fabric, the supporting mechanism opens and supports under the mesh fabric.

[0018] Step S4: When the traction slide pulls the mesh fabric to a set length, the clamping mechanism clamps the rear half of the mesh fabric, the cutting mechanism cuts the mesh fabric, and the traction slide moves away from the cutting mechanism, causing the rear end of the mesh fabric to move to the clamping mechanism; then the conveying component one clamps the front end of the mesh fabric, and the conveying component two clamps the rear end of the mesh fabric; the traction jaw releases the mesh fabric and moves away from the mesh fabric.

[0019] Step S5: The loading and unloading mechanism feeds the center tube onto the supporting and rotating mechanism, the welding beam moves above the center tube, the pushing plate of the pushing component descends, the driving component six drives the pushing plate to abut against one end of the center tube and drives the center tube to move towards the jaw chuck direction, the jaw chuck clamps the other end of the center tube, the pushing plate rises and leaves the center tube; the inner support rod is inserted into the center tube; Step S5 can be executed simultaneously with Steps S1 - S4.

[0020] Step S6: The conveying component one and the conveying component two move the mesh fabric towards the center tube and make the side end of the mesh fabric cross the vertical plane where the center line of the center tube is located; the pressing mechanism presses the end of the mesh fabric against the center tube, the third electrode of the welding component one moves to the avoidance area for welding, and at the same time the inner support rod moves along, so that the fourth electrode corresponds to the third electrode for welding; the conveying component one and the conveying component two release the two ends of the mesh fabric and move to the initial position.

[0021] Step S7: When one side of the mesh fabric is welded to the center tube, the driving part thirteen drives the jaw chuck to rotate a set angle, so that the mesh fabric is wound around the center tube and the other side of the mesh fabric is placed between the third electrode and the fourth electrode, and then the third electrode of the welding component one moves to the avoidance area for welding.

[0022] Step S8: When the mesh fabric is welded to the center tube, the welding beam drives the welding component one to leave the upper end of the center tube, the inner support rod of the welding component two leaves the center tube, the flap of the pressing mechanism lifts, the jaw chuck releases the center tube, and the jacking component jacks up the center tube from the supporting component; the loading and unloading mechanism unloads the center tube with the welded mesh fabric.

[0023] The outstanding and beneficial technical effects of this technical solution compared with the prior art are as follows:

[0024] 1. This technical solution is designed to stack, load, and cut multiple layers of mesh fabric using a loading device. Subsequently, the cut mesh fabric is transported to the welding device by a feeding device, and finally, the welding device welds the mesh fabric to the central tube, realizing the mechanization of the production process and improving production efficiency and quality.

[0025] 2. The loading device of this technical solution transports the mesh fabric in the storage mechanism to the cutting mechanism through a conveying roller mechanism for cutting, eliminating the need for manual stacking and loading of the mesh fabric.

[0026] 3. This technical solution aligns the sides of multiple layers of mesh fabric through a limiting mechanism, preventing misalignment between multiple layers of mesh fabric from affecting production quality and ensuring the yield rate.

[0027] 4. This technical solution welds multiple layers of aligned mesh fabric together through a spot welding mechanism, preventing the mesh fabric from separating and misaligning during subsequent transportation, ensuring the alignment of the mesh fabric after being welded to the central tube, and improving product quality.

[0028] 5. This technical solution is designed with a traction mechanism to take out the cut mesh fabric and transport the mesh fabric to the next station under the operation of the transportation mechanism, thus realizing the transportation of the mesh fabric without manual transportation, improving production efficiency; at the same time, the support mechanism prevents the middle of the mesh fabric from sagging due to its excessive length, thus ensuring the quality of the welded mesh fabric.

[0029] 6. The loading and unloading mechanism designed in this technical solution is used for loading and unloading the central tube. The pressing mechanism presses one end of the mesh fabric onto the central tube at the upper end of the support and rotation mechanism, and the welding mechanism welds one end of the mesh fabric to the central tube. Then, the support and rotation mechanism drives the central tube to rotate to wind the mesh fabric around the central tube. Finally, the welding mechanism welds the other end of the mesh fabric to the central tube, eliminating the need for manual winding of the mesh fabric and improving production efficiency and quality.

[0079] As Figure 13 and Figure 19 , the pressing mechanism 84 includes: a flap 841, the rear end of which is hinged to the frame 1; an eighteenth driving member 842 (a cylinder or a linear motor), which is installed on the frame 1, and the driving end of the eighteenth driving member 842 is hinged to the flap 841, and is used to drive the front end of the flap 841 to move towards the direction of approaching or departing from the supporting assembly 811; a plurality of rotating wheels 843, which are distributed along the length direction of the flap 841 at the edge of the flap 841, and the rotating wheels 843 are hinged to the front end of the flap 841, and are used to movably abut against the mesh cloth 100 and press the mesh cloth 100 against the central tube 200 at the upper end of the supporting assembly 811; an avoidance area 844 is left between adjacent rotating wheels 843, and the welding mechanism 9 welds the mesh cloth 100 to the central tube 200 through the avoidance area 844.

[0080] A control method for a mesh rolling welding machine, which is used for a mesh rolling welding machine, includes the following steps: Step S1: By adjusting the sliding seat 234 to move upward on the first guide rod 233, the first roller 231 and the second roller 232 are separated from each other to open the conveying roller group 23; align and stack multiple layers of mesh cloth 100 in the storage mechanism 21, and make the front end of the mesh cloth 100 pass through the first group of conveying roller groups 23 until the second group of conveying roller groups 23; adjust the position of the first limiting block 261 on the backing plate 24 so that the first limiting block 261 abuts against both sides of the mesh cloth 100; adjust the sliding seat 234 to move downward on the first guide rod 233, so that the first roller 231 and the second roller 232 approach each other to close the conveying roller group 23;

[0081] Step S2: The conveying roller mechanism 22 transports the front end of the mesh fabric 100 to the cutting mechanism 3; the conveying roller mechanism 22 extends the front end of the mesh fabric 100 out of the cutting mechanism 3, and the cutting mechanism 3 cuts off the front end of the mesh fabric 100 to align the front ends of the multiple layers of the mesh fabric 100; Step S1 and Step S2 are only executed when the mesh fabric is initial (during the first feeding), and the subsequent Steps S3 to S8 are completed by the machine. Then, until the mesh fabric 100 of the machine is used up, Steps S1 and S2 are executed again;

[0082] Step S3: The traction slide 42 moves towards the cutting mechanism 3, then the traction jaw 44 clamps the front end of the mesh fabric 100, and the traction slide 42 moves away from the cutting mechanism 3 to pull out the mesh fabric 100. During the process of the traction slide 42 pulling the mesh fabric 100, the conveying roller mechanism 22 transports the mesh fabric 100 to the cutting mechanism 3 for feeding, and the spot welding mechanism 27 performs spot welding on the mesh fabric 100 at a set distance; at the same time, during the process of the traction slide 42 pulling out the mesh fabric 100, the supporting mechanism 6 opens and supports under the mesh fabric 100;

[0083] Step S4: When the traction slide 42 pulls the mesh fabric 100 to a set length, the clamping mechanism 5 clamps the rear half of the mesh fabric 100, the cutting mechanism 3 cuts the mesh fabric 100, and the traction slide 42 moves away from the cutting mechanism 3 again, so that the rear end of the mesh fabric 100 moves to the clamping mechanism 5; then the conveying component one 71 clamps the front end of the mesh fabric 100, and the conveying component two 77 clamps the rear end of the mesh fabric 100; the traction jaw 44 releases the mesh fabric 100 and moves away from the mesh fabric 100;

[0084] Step S5: The loading and unloading mechanism feeds the central tube 200 onto the supporting and rotating mechanism 81, the welding beam 91 moves above the central tube 200, the push plate 962 of the pushing component 96 descends, the driving component six 94 drives the push plate 962 to abut against one end of the central tube 200 and drives the central tube 200 to move towards the jaw chuck 823, the jaw chuck 823 clamps the other end of the central tube 200, and the push plate 962 rises and leaves the central tube 200; the inner support rod 952 is inserted into the central tube 200; Step S5 can be executed simultaneously with Steps S1 - S4, that is, when executing Steps S1 - S4, Step S5 can be executed synchronously. Of course, Step S5 can also be executed after Steps S1 - S4 are completed;

[0085] Step S6: the conveying assembly 1 71 and the conveying assembly 2 77 move the mesh 100 toward the central tube 200, and make the side end of the mesh 100 pass over the vertical plane where the center line of the central tube 200 is located; the pressing mechanism 84 presses the end of the mesh 100 onto the central tube 200, and the third electrode 932 of the welding assembly 1 93 moves to the avoidance area 844 for welding, and at the same time, the inner support rod 952 moves with the welding assembly 1 93, so that the fourth electrode 953 corresponds to the third electrode 932 and realizes welding; the conveying assembly 1 71 and the conveying assembly 2 77 release the two ends of the mesh 100 and move to the initial position; after the step S6 is completed, the machine returns to and re-executes the step S3 until the raw material of the mesh 100 in the storage mechanism 21 is used up, and then re-executes the step S1;

[0086] Step S7: After one side of the mesh 100 is welded to the central tube 200, the driving member 13 824 drives the clamping chuck 823 to rotate to a set angle, so that the mesh 100 is wound on the central tube 200, and the other side of the mesh 100 is placed between the third electrode 932 and the fourth electrode 953, and then the third electrode 932 of the welding assembly 1 93 moves to the avoidance area 844 for welding, so that the mesh 100 is wound and welded to the central tube 200;

[0087] Step S8: After the mesh 100 is welded to the central tube 200, the welding beam 91 drives the welding assembly 1 93 to leave the upper end of the central tube 200, the inner support rod 952 of the welding assembly 2 95 leaves the central tube 200, the flap 841 of the clamping mechanism 84 is lifted, the clamping claw chuck 823 releases the central tube 200, and the lifting assembly 83 lifts the central tube 200 from the supporting assembly 811; the loading and unloading mechanism unloads the central tube 200 welded with the mesh 100.
