Description

Technical Field

[0001] This invention belongs to the technical field of wire mesh end trimming device and trimming method, and particularly relates to a double-sided horizontal wire mesh end trimming device and a method for trimming the ends of the wire mesh using the device. Background Technology

[0002] Due to limitations in welding equipment and processes, welded wire mesh often has a certain length of end on the outermost longitudinal wire. This end needs to be removed upon completion of welding. Since most of the transverse wires are located above the longitudinal wires, existing wire mesh end trimming devices consist of a cutter at the top and a pad below it. The cutter is typically a movable blade. The connection point between the longitudinal and transverse wires is placed on the pad, and the cutter cuts off the transverse wire end along the outer side of the longitudinal wire. During the cutting process, because the lower longitudinal wire is cylindrical, burrs are generated at the end of the transverse wire in the direction of the cutter's movement. These burrs are located in the gap between the transverse and longitudinal wires, preventing them from causing cuts or pricking during use.

[0003] Currently, many wire meshes have different uses, with some horizontal wires located above the vertical wires and others below them. Using existing wire mesh end-trimming devices to trim the ends of double-sided horizontal wire meshes presents the following drawbacks: when cutting the ends of horizontal wires located below the vertical wires, burrs are formed below the horizontal wires. During use, these burrs are located on the lower surface of the mesh, resulting in low mesh quality. Furthermore, during handling, storage, and use, these burrs on the lower surface can be sharp and irritating, requiring manual removal by hand or grinding wheels. This process is not only time-consuming and labor-intensive, increasing production costs and reducing efficiency, but also occupies space and can easily affect the flatness of the mesh. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a double-sided horizontal wire mesh end trimming device that has a simple structure, does not form burrs on the surface of the mesh, has good mesh flatness, is suitable for assembly line operation, saves time and labor, and has high production efficiency.

[0005] To solve the above problems, the technical solution adopted by the double-sided horizontal wire mesh end trimming device of the present invention is as follows: it includes side fixing plates located on both sides and a lifting plate located between the two side fixing plates. Fixing bolts are provided behind the two side fixing plates. A lifting mechanism fixing pin is provided near the lower part of the two side fixing plates. A lifting mechanism is fixed on the lifting mechanism fixing pin. The top rod of the lifting mechanism is connected to the lifting plate. The lifting mechanism is controlled by a control mechanism. A reset mechanism is provided between the side fixing plates and the lifting plate.

[0006] A first slot with a front opening is provided in front of the side fixing plate, and a second slot corresponding to the first slot is provided on the lifting plate. An upper limit plate is provided between the two side fixing plates above the first slot, and a lower limit plate is provided between the two side fixing plates below the first slot. The lower end face of the upper limit plate is a trapezoid with a wider upper base and a narrower lower base, and the upper end face of the lower limit plate is a trapezoid with a wider lower base and a narrower upper base. An upper cutter is provided on the upper edge of the second slot behind the upper limit plate, and a lower cutter is provided on the lower edge of the second slot behind the lower limit plate.

[0007] A vertical guide rod is provided between the two side fixing plates, and a vertical guide groove is provided on the lifting plate at a position corresponding to the vertical guide rod, with the vertical guide rod located in the vertical guide groove.

[0008] Its additional technical features are:

[0009] The lifting mechanism is a hydraulic cylinder. Vertical side reset slots are provided on the two side fixed plates. Lifting reset slots are provided at the corresponding positions of the lifting plate and the side reset slots. The reset mechanism includes an upper reset plate and a lower reset plate. A reset spring is provided between the upper reset plate and the lower reset plate. The upper reset plate, the lower reset plate, and the reset spring are inserted into the side reset slots and the lifting reset slots.

[0010] An upper pad groove is provided below the upper limit plate, and an upper pad is provided in the upper pad groove. A lower pad groove is provided above the lower limit plate, and a lower pad is provided in the lower pad groove.

[0011] A groove is provided below the first slot on the inner side of the side fixing plate, a baffle is provided above the groove, and a guide plate is provided between the groove below the baffle and the lifting plate.

[0012] The cross-section of the guide plate is "V" shaped.

[0013] The second technical problem to be solved by the present invention is to provide a method for trimming the ends of a double-sided horizontal wire mesh using the above-mentioned double-sided horizontal wire mesh end trimming device.

[0014] To solve the above problems, the technical solution adopted by the present invention for trimming the ends of the double-sided transverse wire mesh using the aforementioned double-sided transverse wire mesh end trimming device is as follows:

[0015] The method includes the following steps:

[0016] Step 1: Fix the double-sided horizontal wire mesh end trimming device

[0017] The two side fixing plates are fixed to the frame on both sides of the mesh by fixing bolts behind the side fixing plates, so that the outermost longitudinal wire of the mesh is located between the upper limit plate and the lower limit plate, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate and the lower limit plate near the outer side of the mesh.

[0018] The second step is for the mesh to move forward.

[0019] The mesh to be trimmed moves forward on the conveyor mesh frame, with the longitudinal wires closest to the outermost edge of the mesh located between the upper limit plate and the lower limit plate;

[0020] The third step is for the control mechanism to receive information about the position of the cross wires on or below the mesh.

[0021] Based on the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism;

[0022] Step 4: Cut off the end.

[0023] Based on the position information of this horizontal wire on the mesh, the control mechanism controls the lifting mechanism's top rod to push up or retract.

[0024] When this horizontal wire is above the mesh, the control mechanism controls the top rod of the lifting mechanism to retract, the top rod drives the lifting plate to move down, and the upper cutter moves down to cut off the end of the horizontal wire located above the mesh.

[0025] When this horizontal wire is located below the mesh, the control mechanism controls the lifting mechanism's top rod to rise, the top rod drives the lifting plate to move upward, and the lower cutter moves upward to cut off the end of the horizontal wire located below the mesh.

[0026] Step 5: Reset the push rod.

[0027] Under the action of the reset mechanism, the lifting plate returns to its initial position;

[0028] Step 6: Repeat steps 2 through 5 until all the ends of the mesh are trimmed.

[0029] As a further improvement, the method for trimming the ends of a double-sided transverse wire mesh using a trimming device includes the following steps:

[0030] Step 1: Fix the double-sided horizontal wire mesh end trimming device

[0031] The two side fixing plates are fixed to the frame on both sides of the mesh by fixing bolts behind the side fixing plates, so that the outermost longitudinal wire of the mesh is located between the upper limit plate and the lower limit plate, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate and the lower limit plate near the outer side of the mesh.

[0032] The second step is for the mesh to move forward.

[0033] The mesh to be trimmed moves forward on the conveyor mesh frame, with the longitudinal wires closest to the outermost edge of the mesh located between the upper limit plate and the lower limit plate;

[0034] The third step is for the control mechanism to receive information about the position of the cross wires on or below the mesh.

[0035] Based on the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism;

[0036] Step 4: Cut off the end.

[0037] Based on the position information of this horizontal wire on the mesh, the control mechanism controls the hydraulic cylinder's push rod to push up or retract.

[0038] When the horizontal wire is above the mesh, the control mechanism controls the hydraulic cylinder's push rod to retract, the push rod drives the lifting plate to move down, and the upper cutter moves down to cut off the end of the horizontal wire located above the mesh. When the lifting plate moves down, the upper reset pressure plate moves down under the pressure of the lifting plate above the lifting reset strip groove, and the lower reset pressure plate does not move under the restriction of the side fixing plate below the side reset strip groove. At this time, the reset spring is pressed tight.

[0039] When the horizontal wire is located below the mesh, the control mechanism controls the lifting mechanism's top rod to push upward. The top rod drives the lifting plate to move upward, and the lower cutter moves upward to cut off the end of the horizontal wire located below the mesh. When the lifting plate is pushed upward, the lower reset pressure plate moves upward under the pressure of the lifting plate below the lifting reset strip groove, and the upper reset pressure plate does not move under the restriction of the side fixing plate above the side reset strip groove. At this time, the reset spring is compressed.

[0040] Step 5: Reset the push rod.

[0041] After the force of the hydraulic cylinder push rod is removed, the return spring quickly returns to its original state under its own elastic force, and the lifting plate returns to its initial position;

[0042] Step 6: Repeat steps 2 through 5 until all the ends of the mesh are trimmed.

[0043] The double-sided transverse wire mesh end trimming device and the method for trimming the mesh ends using the device provided by this invention have the following advantages compared with the prior art:

[0044] Firstly, the system includes side fixing plates on both sides and a lifting plate between the two side fixing plates. Fixing bolts are provided behind the two side fixing plates, and a lifting mechanism fixing pin is provided near the lower part of the two side fixing plates. A lifting mechanism is fixed to the lifting mechanism fixing pin, and the top rod of the lifting mechanism is connected to the lifting plate. The lifting mechanism is controlled by a control mechanism, and a reset mechanism is provided between the side fixing plates and the lifting plate. A first slot with a front opening is provided in front of the side fixing plates, and a second slot corresponding to the first slot is provided on the lifting plate. An upper limit plate is provided between the two side fixing plates above the first slot. A lower limit plate is provided between the two side fixing plates below the groove. The lower end face of the upper limit plate is a trapezoid with a wider upper base and a narrower lower base, and the upper end face of the lower limit plate is a trapezoid with a wider lower base and a narrower upper base. An upper cutter is provided along the upper edge of the second slot behind the upper limit plate, and a lower cutter is provided along the lower edge of the second slot behind the lower limit plate. A vertical guide rod is provided between the two side fixing plates, and a vertical guide groove is provided on the lifting plate at a position corresponding to the vertical guide rod. The vertical guide rod is located in the vertical guide groove. The two side fixing plates are fixed to the frame on both sides of the mesh by fixing bolts behind the side fixing plates, so that the outermost longitudinal wire of the mesh is located between the upper limit plate and the lower limit plate. Between the plates, the outermost longitudinal wire is aligned with the upper and lower limit plates near the outer surface of the mesh; the mesh to be trimmed moves forward on the conveyor mesh frame, with the outermost longitudinal wire near the mesh positioned between the upper and lower limit plates; based on the position of the transverse wire in the vertical direction of the mesh, the welding machine transmits the position information of the transverse wire on the mesh to the control mechanism; based on the position information of this transverse wire on the mesh, the control mechanism controls the lifting mechanism's top rod to push up or retract; when this transverse wire is above the mesh, the control mechanism controls the lifting mechanism's top rod to retract, the top rod drives the lifting plate to move down, and the upper cutter moves down to cut off the end of the transverse wire located above the mesh; when this transverse wire is below the mesh... The control mechanism controls the lifting mechanism's top rod to rise, which in turn moves the lifting plate upwards, causing the lower cutter to move upwards and cut off the ends of the horizontal wires located below the mesh. Under the action of the reset mechanism, the lifting plate returns to its initial position. This process is repeated until all the ends of the mesh are trimmed. The distance between the upper and lower limit plates should ideally be slightly greater than the diameter of the vertical and horizontal wires. In other words, the distance between the upper and lower limit plates should ideally be slightly greater than the thickness at the intersection of the horizontal and vertical wires. Regardless of whether the horizontal wire is above or below the vertical wire, the burrs generated by the cutting end can be squeezed between the horizontal and vertical wires, preventing burrs from forming on the mesh surface. This eliminates the need for further processing, reducing production costs and labor intensity.Secondly, since the lifting mechanism is a hydraulic cylinder, vertical side reset slots are provided on the two side fixing plates, and lifting reset slots are provided at the corresponding positions of the lifting plate and the side reset slots. The reset mechanism includes an upper reset pressure plate and a lower reset pressure plate, and a reset spring is provided between the upper reset pressure plate and the lower reset pressure plate. The upper reset pressure plate, the lower reset pressure plate and the reset spring are inserted into the side reset slots and the lifting reset slots. The two side fixing plates are fixed to the frame on both sides of the mesh by the fixing bolts behind the side fixing plates, so that the outermost longitudinal wire of the mesh is located between the upper limit plate and the lower limit plate, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate and the lower limit plate near the outer side of the mesh. The wire mesh to be trimmed moves forward on the conveyor frame, with the outermost longitudinal wire positioned between the upper and lower limit plates. Based on the position of the transverse wire in the vertical direction of the mesh, the welding machine transmits the position information of the transverse wire to the control mechanism. According to this position information, the control mechanism controls the hydraulic cylinder's push rod to move upwards or backwards. When the transverse wire is above the mesh, the control mechanism controls the hydraulic cylinder's push rod to retract, causing the push rod to move the lifting plate downwards, and the upper cutter to move downwards, cutting off the end of the transverse wire located above the mesh. As the lifting plate moves downwards, the upper reset plate moves downwards under the pressure of the lifting plate above the reset groove, while the lower reset plate remains stationary under the constraint of the side fixing plate below the side reset groove. During the movement, the return spring is compressed. When the horizontal wire is below the mesh, the control mechanism controls the lifting mechanism's push rod to move upward, causing the lifting plate to rise and the lower cutter to move upward, cutting off the end of the horizontal wire below the mesh. When the lifting plate moves upward, the lower reset plate moves upward under the pressure of the lifting plate below the reset groove, while the upper reset plate remains stationary due to the restriction of the side fixing plate above the side reset groove. At this time, the return spring is compressed. After the hydraulic cylinder push rod force is released, the return spring quickly returns to its original state under its own elasticity, and the lifting plate returns to its initial position. This cycle repeats until all the mesh ends are trimmed. The lifting and lowering of the hydraulic cylinder push rod can be easily controlled by the control mechanism. After the external force is removed, the lifting plate quickly returns to its original position, which is not only accurate but also fast. Of course, the lifting mechanism can also be a servo motor and a lead screw. In this way, although the above functions can be achieved, the reset speed is slow and it cannot be used on a fast mesh welding production line. Moreover, the cost of the equipment is high. Thirdly, since an upper pad groove is set below the upper limit plate and an upper pad is set in the upper pad groove, and a lower pad groove is set above the lower limit plate and a lower pad is set in the lower pad groove, the upper and lower pads can be replaced according to the diameter of the longitudinal and transverse wires of the mesh to adjust the distance between the upper and lower pads so that the distance between the upper and lower pads is slightly greater than the thickness at the intersection of the transverse and longitudinal wires.Fourth, because a groove is provided below the first slot on the inner side of the side fixing plate, and a baffle is provided above the groove, and a guide plate is provided between the groove below the baffle and the lifting plate, metal chips, paint, dust and other impurities generated during cutting are discharged along the guide plate and will not fall above the hydraulic cylinder, thus preventing damage to the hydraulic cylinder or other lifting mechanisms; Fifth, because the cross-section of the guide plate is "V" shaped, it prevents metal chips, paint, dust and other impurities from deviating from the guide plate during the discharge process.

[0053] The structure and working principle of the double-sided horizontal wire mesh end trimming device of the present invention, as well as the method of trimming the end of the mesh using the device, will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The diagram shows the structure of the double-sided horizontal wire mesh end trimming device of the present invention. The device includes side fixing plates 1 located on both sides and a lifting plate 2 located between the two side fixing plates 1. Fixing bolts 3 are provided behind the two side fixing plates 1, and lifting mechanism fixing pins 4 are provided near the lower part of the two side fixing plates 1. A lifting mechanism 5 is fixed to the lifting mechanism fixing pins 4, and the top rod 6 of the lifting mechanism 5 is connected to the lower part of the lifting plate 2. The lifting mechanism 5 is controlled by a control mechanism 7, and a reset mechanism 8 is provided between the side fixing plates 1 and the lifting plate 2. A first slot 9 with a front opening is provided in front of the side fixing plate 1. A second slot 10 corresponding to the first slot 9 is provided on the lifting plate 2. An upper limit plate 11 is provided between the two side fixing plates 1 above the first slot 9, and a lower limit plate 12 is provided between the two side fixing plates 1 below the first slot 9. The lower end face of the upper limit plate 11 is a trapezoid with a wider upper base and a narrower lower base, and the upper end face of the lower limit plate 12 is a trapezoid with a wider lower base and a narrower upper base. An upper cutter 13 is provided on the upper edge of the second slot 10 behind the upper limit plate 11, and a lower cutter 14 is provided on the lower edge of the second slot 10 behind the lower limit plate 12. A vertical guide rod 15 is provided between the two side fixing plates 1, and a vertical guide groove 16 is provided on the lifting plate 2 at a position corresponding to the vertical guide rod 15. The vertical guide rod 15 is located in the vertical guide groove 16.

[0055] The two side fixing plates 1 are fixed to the frame on both sides of the mesh by the fixing bolts 3 behind the side fixing plates 1, so that the outermost longitudinal wire of the mesh is located between the upper limit plate 11 and the lower limit plate 12, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate 11 and the lower limit plate 12 near the outer side of the mesh; the mesh to be trimmed moves forward on the conveying mesh frame, and the longitudinal wire near the outermost of the mesh is located between the upper limit plate 11 and the lower limit plate 12; according to the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism 7; according to the position information of this horizontal wire on the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to push up or retract; when this horizontal wire is above the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to retract, the top rod 6 drives the lifting plate 2 to move down, and the upper cutter 13 moves downward. The end of the horizontal wire located above the mesh is cut off. When this horizontal wire is located below the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to rise. The top rod 6 drives the lifting plate 2 to move upward, and the lower cutter 14 moves upward to cut off the end of the horizontal wire located above the mesh. Under the action of the reset mechanism 8, the lifting plate 2 returns to the initial position. This process is repeated until all the ends of the mesh are trimmed. The distance between the upper limit plate 11 and the lower limit plate 12 is preferably slightly larger than the diameter of the vertical and horizontal wires. That is, the distance between the upper limit plate 11 and the lower limit plate 12 is preferably slightly larger than the thickness at the intersection of the horizontal and vertical wires. Regardless of whether the horizontal wire is above or below the vertical wire, the burrs generated by the cutting end can be squeezed between the horizontal and vertical wires, and no burrs will be generated on the surface of the mesh. No further processing is required, which reduces production costs and labor intensity.

[0056] The lifting mechanism 5 is a hydraulic cylinder 51. Vertical side reset strip grooves 17 are provided on the two side fixed plates 1. Lifting reset strip grooves 18 are provided at the corresponding positions of the lifting plate 2 and the side reset strip grooves 17. The reset mechanism 8 includes an upper reset pressure plate 19 and a lower reset pressure plate 20. A reset spring 21 is provided between the upper reset pressure plate 19 and the lower reset pressure plate 20. The upper reset pressure plate 19, the lower reset pressure plate 20 and the reset spring 21 are inserted into the side reset strip grooves 17 and the lifting reset strip grooves 18. The two side fixing plates 1 are fixed to the frame on both sides of the mesh by fixing bolts 3 behind the side fixing plates 1, so that the outermost longitudinal wire of the mesh is located between the upper limit plate 11 and the lower limit plate 12, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate 11 and the lower limit plate 12 near the outer side of the mesh; the mesh to be trimmed moves forward on the conveyor mesh frame, with the longitudinal wire near the outermost part of the mesh located between the upper limit plate 11 and the lower limit plate 12; according to the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control machine. Structure 7; Based on the position information of this horizontal wire on the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to push up or retract; when this horizontal wire is above the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to retract, the top rod 6 drives the lifting plate 2 to move down, and the upper cutter 13 moves down to cut off the end of the horizontal wire located above the mesh; when the lifting plate 2 moves down, the upper reset pressure plate 19 moves down under the pressure of the lifting plate 2 above the lifting reset strip groove 18, and the lower reset pressure plate 20 does not move down under the restriction of the side fixing plate 1 below the side reset strip groove 17. When the wire moves, the return spring is compressed. When the horizontal wire is below the mesh, the control mechanism 7 controls the lifting mechanism 5 to push the top rod 6 upward. The top rod 6 drives the lifting plate 2 to move upward, and the lower cutter 14 moves upward to cut off the end of the horizontal wire located above the mesh. When the lifting plate 2 pushes upward, the lower return pressure plate 20 moves upward under the pressure of the lifting plate 2 below the lifting return strip groove 18, and the upper return pressure plate 19 does not move under the restriction of the side fixing plate 1 above the side return strip groove 17. At this time, the return spring is compressed. After the force of the hydraulic cylinder 51 push rod is released... The return spring 21 quickly returns to its original state under its own elastic force, and the lifting plate 2 returns to its initial position. This cycle repeats until all the ends of the mesh are trimmed. The lifting and lowering of the hydraulic cylinder rod can be easily controlled by the control mechanism 7. After the external force is removed, the lifting plate quickly returns to its original position. The reset is not only accurate but also fast. Of course, the lifting mechanism 5 can also be a servo motor and a lead screw. In this way, although the above functions can be achieved, the reset speed is slow and it cannot be used on a fast mesh welding production line. Moreover, the cost of the equipment is high.

[0057] An upper pad groove 22 is provided below the upper limit plate 11, and an upper pad 23 is provided in the upper pad groove 22. A lower pad groove 24 is provided above the lower limit plate 12, and a lower pad 25 is provided in the lower pad groove 24. The upper pad 23 and the lower pad 25 can be replaced according to the diameter of the longitudinal and transverse wires of the mesh to adjust the distance between the upper and lower pads so that the distance between the upper and lower pads is slightly greater than the thickness at the intersection of the transverse and longitudinal wires.

[0058] A groove 26 is provided below the first slot on the inner side of the side fixing plate 1, and a baffle 27 is provided above the groove 26. A guide plate 28 is provided between the groove 26 below the baffle 27 and the lifting plate 2, so that metal chips, paint, dust and other impurities generated during the cutting end are discharged along the guide plate 28 and will not fall above the hydraulic cylinder, causing damage to the hydraulic cylinder or other lifting mechanisms.

[0059] The cross-section of the deflector 28 is "V" shaped, which prevents metal shavings, paint, and dust from deviating from the deflector during the discharge process.

[0060] The technical solution adopted in the method of trimming the ends of the double-sided horizontal wire mesh using the above-mentioned double-sided horizontal wire mesh trimming device is as follows:

[0061] The method includes the following steps:

[0062] Step 1: Fix the double-sided horizontal wire mesh end trimming device

[0063] The two side fixing plates 1 are fixed to the frame on both sides of the mesh by fixing bolts 3 behind the side fixing plates 1, so that the outermost longitudinal wire of the mesh is located between the upper limit plate 11 and the lower limit plate 12, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate 11 and the lower limit plate 12 near the outer side of the mesh.

[0064] The second step is for the mesh to move forward.

[0065] The mesh to be trimmed moves forward on the conveyor mesh frame, with the longitudinal wires closest to the outermost edge of the mesh located between the upper limit plate 11 and the lower limit plate 12;

[0066] The third step is for the control mechanism to receive information about the position of the cross wires on or below the mesh.

[0067] Based on the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism 7;

[0068] Step 4: Cut off the end.

[0069] Based on the position information of this horizontal wire on the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to push up or retract.

[0070] When this horizontal wire is above the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to retract, the top rod 6 drives the lifting plate 2 to move down, and the upper cutter 13 moves down to cut off the end of the horizontal wire located above the mesh.

[0071] When this horizontal wire is located below the mesh, the control mechanism 7 controls the lifting mechanism 5 to push the top rod 6 upward. The top rod 6 drives the lifting plate 2 to move upward, and the lower cutter 14 moves upward to cut off the end of the horizontal wire located above the mesh.

[0072] Step 5: Reset the push rod.

[0073] Under the action of the reset mechanism 8, the lifting plate 2 returns to its initial position;

[0074] Step 6: Repeat steps 2 through 5 until all the ends of the mesh are trimmed.

[0075] As a further improvement, the method for trimming the ends of a double-sided transverse wire mesh using a trimming device includes the following steps:

[0076] Step 1: Fix the double-sided horizontal wire mesh end trimming device

[0077] The two side fixing plates 1 are fixed to the frame on both sides of the mesh by fixing bolts 3 behind the side fixing plates 1, so that the outermost longitudinal wire of the mesh is located between the upper limit plate 11 and the lower limit plate 12, and the outer side of the outermost longitudinal wire is aligned with the upper limit plate 11 and the lower limit plate 12 near the outer side of the mesh.

[0078] The second step is for the mesh to move forward.

[0079] The mesh to be trimmed moves forward on the conveyor mesh frame, with the longitudinal wires closest to the outermost edge of the mesh located between the upper limit plate 11 and the lower limit plate 12;

[0080] The third step is for the control mechanism to receive information about the position of the cross wires on or below the mesh.

[0081] Based on the position of the horizontal wire in the vertical direction of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism 7;

[0082] Step 4: Cut off the end.

[0083] Based on the position information of this horizontal wire on the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to push up or retract.

[0084] When the horizontal wire is above the mesh, the control mechanism 7 controls the top rod 6 of the lifting mechanism 5 to retract. The top rod 6 drives the lifting plate 2 to move down, and the upper cutter 13 moves down to cut off the end of the horizontal wire located above the mesh. When the lifting plate 2 moves down, the upper reset pressure plate 19 moves down under the pressure of the lifting plate 2 above the lifting reset strip groove 18, and the lower reset pressure plate 20 does not move under the restriction of the side fixing plate 1 below the side reset strip groove 17. At this time, the reset spring is pressed.

[0085] When the horizontal wire is located below the mesh, the control mechanism 7 controls the lifting mechanism 5 to push the top rod 6 upward. The top rod 6 drives the lifting plate 2 to move upward, and the lower cutter 14 moves upward to cut off the end of the horizontal wire located above the mesh. When the lifting plate 2 pushes upward, the lower reset pressure plate 20 moves upward under the pressure of the lifting plate 2 below the lifting reset strip groove 18. The upper reset pressure plate 19 does not move under the restriction of the side fixing plate 1 above the side reset strip groove 17. At this time, the reset spring is pressed.
