Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of welding device and welding method, and particularly relates to a shelf net welding device and a method for welding a shelf net by using the device. BACKGROUND

[0002] In order to increase the strength of the shelf net and avoid hindering the discharge of goods, the horizontal wires in the middle of the shelf net are located above the vertical wires, and the horizontal wires at the outermost sides of the two ends are located below the vertical wires. Currently, the shelf net welding generally adopts the following two methods: one is to first weld the horizontal wires above the vertical wires by using a common welding machine, then turn over the net sheet, and manually weld the two horizontal wires at the outermost sides of the two ends of the vertical wires; this method has low working efficiency, high labor intensity, and poor welding quality due to small pressure during manual welding, and poor flatness of the end of the net sheet. The other is to set horizontal wire feeding mechanisms with horizontal wire channels above and below the net sheet channel, before welding the net sheet, first position the horizontal wire above the lower welding head by using the horizontal wire feeding mechanism below the net sheet channel, pull the vertical wire forward, weld the vertical wire and the first horizontal wire, then position the horizontal wire above the vertical wire by using the horizontal wire feeding mechanism above the net sheet channel, and then weld, until the last horizontal wire above the vertical wire is welded, and finally position the horizontal wire above the lower welding head by using the horizontal wire feeding mechanism below the net sheet channel, and weld the vertical wire and the last horizontal wire; this method improves the production efficiency, improves the welding quality of the net sheet, and reduces the labor intensity, but the equipment cost is greatly increased due to the setting of the horizontal wire feeding mechanisms with horizontal wire channels above and below the net sheet channel, the height of the welding equipment is increased due to the setting of the horizontal wire feeding mechanism below the net sheet channel, the stability is poor, the feeding difficulty of the two horizontal wire feeding mechanisms is increased, and the horizontal wire of the horizontal wire feeding mechanism below cannot be lowered to the welding head due to its own gravity, and needs to be pushed by a pushing mechanism, so the structure is complex. SUMMARY

[0003] The first technical problem to be solved by the present application is to provide a shelf net welding device with high production efficiency, low labor intensity, good welding quality of the net sheet, low equipment cost, and convenient operation.

[0004] To solve the above problems, the technical solution adopted by the shelving mesh welding device of the present invention is as follows: A frame with a lower fixed beam and an upper movable beam is provided. A lower welding head and an upper welding head are provided on the lower fixed beam and the upper movable beam, forming a mesh channel between the upper welding head and the lower welding head.

[0008] The first step is to lay the first horizontal wire.

[0009] Open the cross wire feeding mechanism, and the first cross wire falls and is positioned above the lower welding head along the cross wire channel;

[0010] The second step is to raise the threading opening of the longitudinal wire.

[0011] The lifting cylinder of the threading port pushes up, making the lower end face of the longitudinal wire higher than the upper end face of the first transverse wire.

[0012] The third step is to move the silk threads forward.

[0013] Push all the longitudinal threads forward so that they press down on top of the first transverse thread;

[0014] The fourth step is to weld the first horizontal wire and the first vertical wire together.

[0015] The upper movable beam moves down, and the upper and lower welding heads weld the first horizontal and vertical wires together.

[0016] Step 5: Pull the net

[0017] Fix the net pulling hook of the net pulling trolley to the first horizontal wire, and pull the net pulling trolley forward one mesh distance;

[0018] Step 6: Lower the threading opening of the longitudinal yarn.

[0019] The top rod of the lifting cylinder at the wire threading port retracts, causing the lower end face of the longitudinal wire to be slightly lower than the upper end face of the welding head.

[0020] Step 7: The horizontal wire falls.

[0021] Open the horizontal wire feeding mechanism, and the horizontal wire falls and is positioned above the lower welding head along the horizontal wire channel;

[0022] Step 8: Weld the horizontal and vertical wires located above the lower welding head.

[0023] The upper movable beam moves down, and the upper and lower welding heads weld the horizontal and vertical wires located above the lower welding head together;

[0024] Step 9: Continue pulling the net.

[0025] Continue pulling the net-pulling trolley forward by one mesh size;

[0026] Step 10: Repeat steps 5 through 7 until the last horizontal wire above the vertical wire is completed;

[0027] Step 11: Continue pulling the net forward.

[0028] Continue pulling the mesh forward so that the rear end of the longitudinal wire detaches from the lower welding head;

[0029] Step 12, the last horizontal wire falls.

[0030] Open the cross wire feeding mechanism, and the last cross wire falls and is positioned above the lower welding head along the cross wire channel;

[0031] Step 13: Lift the back of the mesh panel

[0032] Use the cylinder push rod to lift the mesh support plate and raise the rear end of the mesh so that the rear end of the longitudinal wire is above the last transverse wire;

[0033] Step 14: Push the mesh backward.

[0034] The netting trolley pushes the netting backward, causing the longitudinal wires to overlap the upper ends of the transverse wires;

[0035] Step 15, Welding

[0036] Weld the longitudinal wire and the last transverse wire together;

[0037] Step sixteen: Pull the net

[0038] Use a wire mesh pulling cart to pull the mesh forward, causing it to detach from the welding machine.

Opposite lower and upper welding heads are provided on the lower fixed beam and the upper movable beam, forming a mesh channel between the upper and lower welding heads. A longitudinal wire feeding mechanism is provided behind the frame, comprising a feeding frame and a pushing mechanism. A longitudinal wire threading port is provided in front of the longitudinal wire feeding mechanism. A mesh pulling trolley, powered by a mesh pulling motor, is provided in front of the frame.

A wire-threading port lifting cylinder is installed below the longitudinal wire threading port, and its push rod is connected to the longitudinal wire threading port. When the horizontal wire feeding mechanism is opened, the first horizontal wire falls along the horizontal wire channel above the lower welding head and is positioned. The push rod of the wire-threading port lifting cylinder then pushes upwards. The lower end face of the longitudinal wire is made higher than the upper end face of the first transverse wire; all longitudinal wires are pushed forward so that they press above the first transverse wire; the upper movable beam moves down, and the upper and lower welding heads weld the first transverse and longitudinal wires together; the mesh pulling hook of the mesh pulling trolley is fixed to the first transverse wire, and the mesh pulling trolley is pulled forward one mesh distance; the top rod of the threading port lifting cylinder retracts, so that the lower end face of the longitudinal wire is slightly lower than the upper end face of the welding head; the transverse wire feeding mechanism is opened, and the transverse wire falls along the transverse wire channel above the lower welding head and is positioned; the upper movable beam moves down, and the upper and lower welding heads weld the transverse and longitudinal wires located above the lower welding head. Together; pull the mesh-pulling trolley forward one mesh opening; continue welding until the last horizontal wire above the longitudinal wire is completed; pull the mesh sheet forward again so that the rear end of the longitudinal wire is detached from the lower welding head; open the horizontal wire feeding mechanism, and the last horizontal wire falls along the horizontal wire channel above the lower welding head and is positioned; use the cylinder push rod to lift the mesh sheet support plate, raising the rear end of the mesh sheet so that the rear end of the longitudinal wire is above the last horizontal wire; push the mesh sheet backward with the mesh-pulling trolley so that the longitudinal wire overlaps the upper end of the horizontal wire; weld the longitudinal wire and the last horizontal wire together; pull the mesh sheet forward with the mesh-pulling trolley to detach the mesh sheet from the welding machine. The entire welding process is completed at once on the same equipment, resulting in high production efficiency and low labor intensity. The entire equipment uses a horizontal wire feeding mechanism located above the mesh sheet channel, allowing the horizontal wire to fall by its own weight, greatly reducing equipment costs and effectively lowering the equipment height.
