Description

Technical Field

[0001] This technical solution relates to the field of wire mesh welding equipment technology, specifically to a feeding device for a wire mesh welding machine. Background Technology

[0002] In the process of oil and gas drilling and production, screen pipes are usually used for sand control to prevent sand from being produced in oil and gas wells, which could damage casing and equipment and reduce production.

[0003] For example, Chinese patent CN202110256197.5 discloses a sand-control screen pipe and its application, and Chinese patent CN200620012375.0 discloses a multi-layer stainless steel metal mesh sand-control screen pipe. These screen pipes generally include an inner central pipe (also called an inner sheath or base pipe) and a mesh cloth (including an inner drainage mesh and a variable precision composite sand-blocking layer, or a metal mesh sand-control screen sleeve) wrapped around the outside of the central pipe.

[0004] However, there are still some shortcomings in the existing screen tube production process: the rolled mesh needs to be unrolled manually, then the unrolled mesh needs to be aligned and stacked to form a set number of meshes, and then the mesh needs to be welded to the central tube manually or by machine. Material feeding is also done manually, resulting in low production efficiency and high production costs. Summary of the Invention

[0005] The purpose of this technical solution is to provide a feeding device for a wire mesh welding machine, which uses a conveying roller mechanism to pull out the wire mesh from the storage mechanism and transport it to the cutting mechanism for cutting, thereby improving the problem of low production efficiency and high production cost caused by manual feeding of wire mesh.

[0077] 100. Mesh fabric. Detailed Implementation

[0078] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0079] like Figure 1 As shown, a feeding device for a wire mesh welding machine is used to align and feed several wire mesh fabrics 100, including:

[0080] Rack 1;

[0081] The storage mechanism 21 is installed on the frame 1 and is used to store several rolls of mesh fabric 100. In this technical solution, the storage mechanism 21 stores at least two rolls of mesh fabric 100.

[0082] The conveying roller mechanism 22 is mounted on the frame 1 and located next to the storage mechanism 21, and is used to transport the mesh 100 in the storage mechanism 21 to a set position.

[0083] The cutting mechanism 3 is mounted on the frame 1 and is located at the discharge end of the conveying roller mechanism 22. It is used to cut the mesh fabric 100 transported by the conveying roller mechanism 22.

[0084] By pulling out and aligning one end of various mesh fabrics 100 (mesh fabric rolls), the front end of the mesh fabric 100 is placed in the conveying roller mechanism 22. The conveying roller mechanism 22 then moves the front end of the mesh fabric 100 and extends it out of the cutting mechanism 3. The cutting mechanism 3 cuts off the front end of the mesh fabric 100 to ensure the neatness of the front end of the mesh fabric 100, thereby ensuring the quality of the mesh fabric 100 after it is welded to the central tube.

[0085] Combination Figures 1-3 The conveying roller mechanism 22 includes:

[0086] Several sets of conveyor rollers 23 are arranged on the frame 1;

[0087] Several pads 24 are alternately arranged on the frame 1 with several sets of conveyor rollers 23. That is, the conveyor rollers 23 and the pads 24 are arranged one after another on the frame 1. The pads 24 are used to support the lower end of the mesh 100. The conveyor rollers 23 drive the mesh 100 to move to the set position on the upper end of the pads 24.

[0088] Drive component 1 is mounted on frame 1 and connected to conveyor roller assembly 23, and is used to drive conveyor roller assembly 23 to rotate.

[0089] The conveyor roller assembly 23 includes:

[0090] The first roller 231 is rotatably mounted on the frame 1 at both ends and connected to the drive end of the drive assembly 1.

[0091] The second roller 232 is rotatably mounted on the frame 1 at both ends and is positioned above the first roller 231;

[0092] The end of the mesh fabric 100 passes between the first roller 231 and the second roller 232, and the second roller 232 and the first roller 231 respectively abut against the upper and lower end faces of the mesh fabric. When the drive assembly drives the first roller 231 to rotate, the first roller 231 and the second roller 232 respectively move against the two end faces of the mesh fabric 100 and drive the mesh fabric 100 to move on the pad 24 to the cutting mechanism 3.

[0093] Combination Figures 1-3 A guide rod 233 is vertically mounted on the frame 1. A slide block 234 is slidably mounted on the guide rod 233. The end of the second roller 232 is rotatably connected to the slide block 234. An adjusting component 235 is provided at the end of the guide rod 233. The adjusting component 235 is a hand valve or a cylinder. The driving end of the adjusting component 235 is connected to the slide block 234 and is used to drive the slide block 234 to slide up and down on the guide rod 233.

[0094] The sliding block 234 is driven to slide on the guide rod 233 by the adjusting component 235, so that the sliding block 234 drives the second roller 232 to move up and down, thereby adjusting the distance between the second roller 232 and the first roller 231. After the distance between the second roller 232 and the first roller 231 is increased by the adjusting component 235, it is convenient for the end of the mesh 100 to pass through. After the mesh 100 passes through, the distance between the second roller 232 and the first roller 231 is reduced by the adjusting component 235, thereby clamping the mesh 100 to achieve transportation.

[0095] Combination Figure 1 and Figure 2 Driver component one includes:

[0096] The drive component 251 is a motor or a rotary cylinder, which is mounted on the frame 1;

[0097] The sprocket and chain assembly 252 (including two sprockets and a chain connecting the two sprockets, the two sprockets being connected to the end of the first roller 231 and the drive end of the drive member 251 respectively) is connected to the drive end of the drive member 251 and the end of the first roller 231 of one of the conveying roller assemblies 23.

[0098] The ends of two adjacent first rollers 231 are connected by a sprocket and chain assembly 253 (including two sprockets and a chain);

[0099] When the drive unit 251 drives one of the first rollers 231 to rotate through the sprocket and chain assembly 252, the first roller 231 drives the adjacent first roller 231 to rotate through the sprocket and chain assembly 253, thereby enabling all the conveying roller assemblies 23 to work to transport the mesh fabric 100.

[0100] Alternatively, driver component one includes:

[0101] Several driving components 251, which are motors or rotary cylinders, correspond to several first rollers 231;

[0102] Several sets of sprocket and chain groups 252 are respectively connected to the drive end of the corresponding drive unit 251 and the end of the corresponding first roller 231;

[0103] A corresponding conveyor roller group 23 is driven by a drive component 251 and a set of sprocket and chain groups 252. Each conveyor roller group 23 is driven by its corresponding drive component 251 and sprocket and chain groups 252.

[0104] Combination Figures 1-3 The feeding device also includes:

[0105] The limiting mechanism, which is installed on the frame 1, is used to limit the mesh fabric 100 in the conveying roller mechanism 22 to avoid misalignment of the mesh fabric 100 after multiple layers are stacked during transportation.

[0106] The limiting mechanism includes:

[0107] Several limiting blocks 261 are installed on both sides of the pad 24 of the conveying roller mechanism 22 to movably abut against both sides of the mesh fabric 100 located on the upper end of the pad 24, thereby ensuring that the left and right edges of the mesh fabric 100 after several layers are stacked are aligned during transportation, and avoiding misalignment.

[0108] The pad 24 has a strip hole 241. The limiting block 261 is connected to the strip hole 241 by a fastener (screw or bolt). In this technical solution, a connecting block is provided at the lower end of the pad 24 and connected to the fastener. The limiting block 261 and the connecting block are clamped on the upper and lower end faces of the pad 24, thereby fixing the position of the limiting block 261.

[0109] By adjusting the position of the fixing component 1 within the strip hole 241, the position of the limiting block 261 installed on the pad 24 is adjusted, thereby adjusting the spacing between the limiting blocks 261 at both ends of the pad 24. This ensures that when feeding mesh fabrics 100 of different widths, the limiting blocks 261 can abut against both sides of the mesh fabric, thus ensuring that the edges of the multi-layered mesh fabrics 100 can be aligned and avoiding misalignment.

[0110] like Figure 3 As shown, the feeding device also includes:

[0111] The spot welding mechanism 27 is mounted on the frame 1 and is used to spot weld the multi-layer mesh 100 in the conveyor roller mechanism 22, thereby avoiding misalignment of the mesh edge;

[0112] The spot welding mechanism 27 includes:

[0113] The bracket 271 is mounted on the frame 1 and is located at the side end of the pad 24 of the conveyor roller mechanism 22;

[0114] The first electrode is mounted on the bracket 271 to support the lower end of the mesh 100 located at the lowest end;

[0115] The welding torch 273 is slidably mounted on the bracket 271 (a cylinder is provided at the upper end of the bracket 271, and the driving end of the cylinder is connected to the welding torch 273), and the welding torch 273 can move toward or away from the first electrode.

[0116] The second electrode, which is mounted on the welding gun 273, is used to press the upper mesh 100 against the lower mesh 100 to weld the multiple meshes 100 together.

[0117] The pad 24 of the conveying roller mechanism 22 is provided with a clearance opening 242. The side edge of the mesh 100 is movably placed at the upper end of the clearance opening 242. The second electrode is located above the clearance opening 242 and extends movably into the clearance opening 242. The first electrode is located below the clearance opening 242 or inside the clearance opening 242. The first electrode and the second electrode are used to weld the mesh 100 located at the clearance opening 242. The specific structure of the spot welding mechanism 27 can be found in Chinese Patent CN202210324741.X, and will not be described in detail here.

[0118] Combination Figure 4 and Figure 5 The adjudication body 3 includes:

[0119] Support frame 31 is mounted on frame 1 and located beside the discharge end of conveyor roller mechanism 22;

[0120] Guide rail 32 is vertically mounted on support frame 31;

[0121] Blade 33 is slidably mounted on guide rail 32 via slider 1. Blade 33 is connected to mounting plate 1, which is slidably connected to guide rail 32 via slider 1.

[0122] The crossbeam 34 is connected to both ends of the blade 33 via a connecting plate 341 at each end.

[0123] Blade 2 35 is slidably mounted on guide rail 1 32 via slider 2 and located between crossbeam 34 and blade 1 33. Blade 2 35 and blade 1 33 form a cutting zone 30. Blade 2 35 is connected to mounting plate 2, which is slidably connected to guide rail 1 32 via slider 2.

[0124] The second driving component 36 is a cylinder or linear motor, which is mounted on the crossbeam 34. The driving end of the second driving component 36 is movably connected to the second blade 35, which is used to drive the second blade 35 to move closer to or away from the first blade 33, thereby cutting the mesh 100 located in the cutting area 30. When the driving end of the second driving component 36 drives the second blade 35 to move towards the first blade 33, the second driving component 36 will generate a reaction force on the crossbeam 34, thereby causing the crossbeam 34 to move away from the second blade 35. The crossbeam 34 will drive the first blade 33 to move closer to the second blade 35, so that the second blade 35 and the first blade 33 move closer to each other and cut the mesh 100.

[0125] The limiting member 311 is installed on the support frame 31 and moves against the lower end of the blade 35 to limit the sliding of the blade 35 on the guide rail 32. After the lower end of the blade 35 abuts against the limiting member 311, the blade 35 is in the initial position.

[0126] Alternatively, the adjudication body 3 includes:

[0127] Support frame 31 is mounted on frame 1 and located beside the discharge end of conveyor roller mechanism 22;

[0128] Blade 33 is slidably mounted on support frame 31 via slider 3;

[0129] Blade 2 35 is slidably mounted on support frame 1 31 via slider 2, and cutting zone 30 is formed between blade 2 35 and blade 1 33;

[0130] The second driving component 36 is a cylinder or a linear motor, which is mounted on the first support frame 31. The driving end of the second driving component 36 is movably connected to the second blade 35, which is used to drive the second blade 35 to move closer to or away from the first blade 33, so as to cut the mesh 100 located in the cutting area 30.

[0131] Combination Figure 4 and Figure 5 The frame 1 is equipped with a buffer 37, and the upper end of the buffer 37 is fitted with an elastic element 371 (spring, disc spring or rubber block). The elastic element 371 is used to move and abut against the lower end of the second blade 35, thereby limiting the movement of the second blade 35 on the first guide rail 32, preventing the second blade 35 from colliding with the limiting element 311 due to its excessive weight when returning to the initial position, and reducing noise and wear.

[0132] like Figure 5 The support frame 31 is equipped with a driving component 38, which is a cylinder or a linear motor. The driving end of the driving component 38 is connected to a pressure bar 381, which is located above the pad 24 at the discharge end of the conveying roller mechanism 22.

[0133] The pressure bar 381 is moved by the driving component 38, so that the pressure bar 381 moves toward the upper end of the pad 24, thereby pressing the mesh fabric 100 onto the pad 24, ensuring that the mesh fabric 100 will not be displaced on the pad 24 when the cutting mechanism 3 cuts the mesh fabric 100.

[0134] Combination Figures 1-3 The storage mechanism 21 includes:

[0135] Several material racks 211 are installed on the frame 1 and located beside the feed end of the conveyor roller mechanism 22 for storing the mesh fabric 100.

[0136] Guide rod 212 is mounted on the frame 1 and located next to the feed end of the conveyor roller mechanism 22, and is used to movably abut against the end face of the mesh 100;

[0137] Several limiting blocks 213 are installed on the guide rod 212, and two limiting blocks 213 respectively move to abut against the two sides of the mesh 100, thereby ensuring the accuracy of the feeding position of the mesh 100;

[0138] The material rack 211 includes a material rack, a material rack, and a motor for driving the material rack to rotate. The material rack is inserted into the middle of the mesh roll, and the two ends of the material rack are rotatably connected to the material rack. The mesh 100 is fed to the first set of conveyor rollers 23 by driving the material rack to rotate through the motor.

[0139] In use, the conveyor roller assembly 23 is opened by adjusting the slide 234 to move upward on the guide rod 233, so that the first roller 231 and the second roller 232 move away from each other; the multi-layer mesh fabric 100 in the storage mechanism 21 is aligned and stacked, so that the front end of the mesh fabric 100 passes through the first conveyor roller assembly 23 until it reaches the second conveyor roller assembly 23; the position of the limiting block 261 on the pad 24 is adjusted so that the limiting block 261 abuts against both sides of the mesh fabric 100; the slide 234 is adjusted to move downward on the guide rod 233, so that the first roller 231 and the second roller 232 move closer to each other;

[0140] 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, so that the front ends of the multiple layers of mesh fabric 100 are aligned; then the conveying roller mechanism 22 transports the mesh fabric 100 and extends it out from the cutting mechanism 3, and the conveying roller mechanism 22 transports the mesh fabric 100 to the next station or processing equipment. After the mesh fabric 100 reaches the set length, the cutting mechanism 3 cuts the mesh fabric 100. Through mechanized feeding and cutting operations, labor costs are saved and production efficiency is improved. The mesh fabric in the storage mechanism 21 is used up before manual replenishment of raw materials is required, saving time and effort.
