Description

Technical Field

[0001] This invention belongs to the technical field of metal mesh trimming devices, and particularly relates to a fine-weave mesh trimming machine and a method for trimming edges using the same. Background Technology

[0002] Originally, metal mesh only had a structure where cross-shaped and longitudinal wires were welded together. Newer metal meshes include a structure where cross-shaped steel strips are welded to the cross-shaped wires. The edges of the welded cross-shaped wires are uneven, requiring trimming. Current cross-shaped wire trimming machines can only trim the edges of metal meshes where the cross-shaped and longitudinal wires are welded together; they cannot trim the edges of metal meshes where steel strips are welded to the cross-shaped wires. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a fine mesh trimming machine that can trim the edges of metal mesh sheets that are welded together with horizontal and vertical wires, as well as metal mesh sheets that are welded together with steel strips and horizontal wires.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: It includes a frame, on which a pair of horizontal wire corner cutters are arranged on the left and right sides. The horizontal wire corner cutter includes an upper wire pressing seat fixing seat, a middle wire pressing seat fixing seat, a lower wire pressing seat fixing seat, and a hydraulic cylinder. The upper wire pressing seat fixing seat is provided with an upper wire pressing seat and a pair of upper wire pressing seat fixing seat connecting plates. The middle wire pressing seat fixing seat connecting plate is provided with a middle wire pressing seat and a pair of middle wire pressing seat fixing seat connecting plates. The lower wire pressing seat fixing seat is provided with a lower wire pressing seat and a pair of lower wire pressing seat fixing seat connecting plates. The middle wire pressing seat fixing seat connecting plate is fixed to the upper wire pressing seat fixing seat connecting plate. The upper wire pressing seat fixing seat connecting plate and the lower wire pressing seat fixing seat connecting plate are connected by a first intermediate connecting plate. The upper wire pressing seat fixing seat connecting plate and the first intermediate connecting plate are connected by a first upper bolt. The upper wire pressing seat fixing seat connecting plate is provided with a first elongated hole matching the first upper bolt. The lower wire pressing seat fixing seat connecting plate is connected to the first intermediate connecting plate by a first lower bolt. The pair of upper pressure wire seat fixing base connecting plates are provided with an upper cutting blade connecting plate with an upper cutting blade, and the pair of lower pressure wire seat fixing base connecting plates are provided with a lower cutting blade connecting plate with a lower cutting blade. The upper cutting blade connecting plate and the lower cutting blade connecting plate are connected by a second intermediate connecting plate and the upper cutting blade connecting plate are connected by a second upper bolt. The upper cutting blade connecting plate is provided with a second elongated hole that matches the second upper bolt. The lower cutting blade connecting plate is connected to the second intermediate connecting plate by a second lower bolt. The lower end of the lower cutting blade connecting plate is connected to the oil cylinder. A waste baffle is provided below the lower pressure wire seat fixing base, a discharge pipe is provided below the waste baffle, a waste conveyor belt is provided on the frame at the matching position of the discharge pipe, and a waste collection box is provided at the end of the waste conveyor belt.

[0005] The second technical problem to be solved by the present invention is to provide a method for trimming edges using a fine mesh trimming machine.

[0006] To solve the above problems, the technical solution adopted by the present invention includes the following steps: The first step, when trimming the metal mesh sheet where the strip steel plate and cross wires are welded together, is to loosen the first upper bolt, adjust the upper wire pressing seat fixing plate vertically, and move the first upper bolt up and down within the first elongated hole. Simultaneously, loosen the second upper bolt, adjust the upper cutter connecting plate vertically, and move the second upper bolt up and down within the second elongated hole. This allows the distance between the upper and lower cutters to adapt to cutting mesh sheets of different heights of strip steel plates. After determining the distance between the upper and lower cutters, tighten the first and second upper bolts. The total stroke of the hydraulic cylinder piston rod is 30 centimeters. Normally, the piston rod extends 15 centimeters. The piston rod drives the upper and lower cutting blade connecting plates to move synchronously. When shearing a strip of steel with an upper horizontal wire at the top and a lower horizontal wire at the bottom, the upper horizontal wire is between the upper and middle pressure wire seats, and the lower horizontal wire is between the lower and middle pressure wire seats. The piston rod first moves upwards by a predetermined length, and the upper and lower cutting blade connecting plates move upwards synchronously. The lower cutting blade moves upwards to cut the bottom of the strip of steel. The lower cross wire is cut, and then the piston rod of the hydraulic cylinder moves downwards by a second set length, which is twice the first set length. The upper and lower cutting blade connecting plates move downwards simultaneously, and the upper cutting blade cuts the upper cross wire at the top of the strip. Finally, the piston rod of the hydraulic cylinder moves upwards by the first set length, returning the piston rod to its normal position, ready for the next shearing. When shearing metal mesh with cross wires only at the top or bottom of the strip, the side of the strip with cross wires is placed downwards, and the cross wires are in the lower pressure wire seat. Between the intermediate wire pressing seat, the piston rod of the hydraulic cylinder first moves upward by a first set length, and the upper cutter connecting plate and the lower cutter connecting plate move upward simultaneously. The lower cutter moves upward to cut the transverse wire on the side of the strip steel plate that is placed downward. Then the piston rod of the hydraulic cylinder moves downward by a first set length, and the piston rod of the hydraulic cylinder returns to its normal state, ready for the next shearing. The cut transverse wire ends fall onto the waste baffle, then enter the discharge pipe through the waste baffle, and then fall onto the waste conveyor belt through the discharge pipe. Finally, the waste wire falls into the waste collection box at the end of the waste conveyor belt. The second step involves trimming the metal mesh where the horizontal and vertical wires are welded together. Loosen the first upper bolt and adjust the upper wire pressing seat fixing plate vertically. The first upper bolt moves up and down within the first elongated hole. Simultaneously, loosen the second upper bolt and adjust the upper cutter connecting plate vertically. The second upper bolt moves up and down within the second elongated hole, allowing the distance between the upper and lower cutters to adapt to cutting mesh with different wire diameters. After determining the distance between the upper and lower cutters, tighten the first and second upper bolts and begin cutting. At this time, the horizontal wire is between the lower wire pressing seat and the middle wire pressing seat. The piston rod of the hydraulic cylinder first moves upward by a first set length. The upper cutter connecting plate and the lower cutter connecting plate move upward simultaneously. The lower cutter moves upward to cut the horizontal wire. Then the piston rod of the hydraulic cylinder moves downward by a first set length, restoring the piston rod of the hydraulic cylinder to its normal state, preparing for the next cutting. The cut horizontal wire ends fall onto the waste baffle, then enter the discharge pipe through the waste baffle, and then fall onto the waste conveyor belt through the discharge pipe. Finally, it falls into the waste collection box at the end of the waste conveyor belt.

[0007] The dense mesh trimming machine provided by this invention trims the edges of metal mesh sheets where strip steel plates and cross wires are welded together. The first upper bolt is loosened, and the upper pressure wire seat fixing plate is adjusted vertically. The first upper bolt moves up and down within the first elongated hole. Simultaneously, the second upper bolt is loosened, and the upper cutter connecting plate is adjusted vertically. The second upper bolt moves up and down within the second elongated hole, allowing the distance between the upper and lower cutters to adapt to cutting mesh sheets with strip steel plates of different heights. After the distance between the upper and lower cutters is determined, the first and second upper bolts are tightened. The total stroke of the piston rod of the hydraulic cylinder is 30 centimeters, and the piston rod normally extends 15 centimeters. The piston rod of the hydraulic cylinder drives the upper and lower cutter connecting plates to move synchronously. When shearing a metal mesh strip with an upper horizontal wire at the top and a lower horizontal wire at the bottom, the upper horizontal wire is positioned between the upper and middle pressure wire seats, and the lower horizontal wire is positioned between the lower and middle pressure wire seats. The piston rod of the hydraulic cylinder first moves upward by a first set length, and the upper and lower cutting blade connecting plates move upward simultaneously. The lower cutting blade moves upward to cut the lower horizontal wire at the bottom of the strip. Then, the piston rod of the hydraulic cylinder moves downward by a second set length, which is twice the first set length. The upper and lower cutting blade connecting plates move downward simultaneously, and the upper cutting blade moves downward to cut the upper horizontal wire at the top of the strip. Finally, the piston rod of the hydraulic cylinder moves upward by a first set length, restoring the piston rod to its normal position, ready for the next shearing operation. When shearing metal mesh strips with cross wires only at the top or bottom of the strip, the strip with the cross wires facing down is placed between the lower and middle pressure wire seats. The piston rod of the hydraulic cylinder first moves upward by a first set length, and the upper and lower cutting blade connecting plates move upward simultaneously. The lower cutting blade moves upward and cuts the cross wires on the downward-facing side of the strip. Then, the piston rod of the hydraulic cylinder moves downward by the first set length, returning to its normal position, ready for the next shearing. The cut cross wire ends fall onto the waste baffle, then enter the discharge pipe, and then fall onto the waste conveyor belt. Finally, they fall into the waste collection box at the end of the waste conveyor belt.

[0008] The dense mesh trimming machine provided by this invention trims the edges of metal mesh sheets where horizontal and vertical wires are welded together. First, the upper bolt is loosened, and the upper pressure wire seat fixing plate is adjusted vertically. The first upper bolt moves up and down within the first elongated hole. Simultaneously, the second upper bolt is loosened, and the upper cutter connecting plate is adjusted vertically. The second upper bolt moves up and down within the second elongated hole, allowing the distance between the upper and lower cutters to adapt to cutting mesh sheets with horizontal wires of different diameters. After the distance between the upper and lower cutters is determined, the first and second upper bolts are tightened. During cutting, the horizontal wire is between the lower pressure wire seat and the middle pressure wire seat. The piston rod of the hydraulic cylinder first moves upward by a first set length, and the upper and lower cutter connecting plates move upward synchronously. The lower cutter moves upward to cut the horizontal wire. Then, the piston rod of the hydraulic cylinder moves downward by a first set length, returning the piston rod to its normal position, ready for the next cutting. The cut horizontal wire ends fall onto the waste baffle, then enter the discharge pipe through the waste baffle, and then fall onto the waste conveyor belt through the discharge pipe. Finally, the waste wire ends into the waste collection box at the end of the waste conveyor belt.

[0009] The mesh trimming machine provided by this invention is multi-functional. It can trim the edges of metal mesh sheets with horizontal and vertical wires welded together, as well as metal mesh sheets with steel strips and horizontal wires welded together, thus meeting different needs.
