In order to let everyone know more about the debugging process of the wire mesh machine, the following is the debugging process:
4.1 Flat-woven opening device and adjustment
4.1.1 The warp opening is realized by the cam pair and the pedal lever and the pedal heald lever system.
4.1.2 Tappet installation, in opening closed position, at crankshaft angle315° is the standard. And according to the change of different network classes to adjust
4.1.3 The adjustment of the opening, within the scope of the rapier through, the rapier head can pass as the principle, try to make the opening small. When the opening is at its maximum, the gap between the upper warp and the sword band is8mmLeft and right is appropriate. In this way, the quality of the net surface can be guaranteed and the warp thread broken due to too much tension can be avoided.
The size of the opening can be adjusted by adjusting the upper and lower positions in the pedal lever.If the opening needs to be reduced, the pedal rod will be adjusted upward; if the opening needs to be increased, the pedal rod will be adjusted downward. And the journey of the same heald must be the same.
4.2 Preparation of main motion gear
There are two pairs of main motion gears. When weaving square mesh, prepare44:88Gear set, speed ratio2:1; When weaving dense grain mesh
When, preparation24：96Gear set, speed ratio4:1
4.3 Coiling device
4.3.1 Installation position of the curling cam
The crankshaft angle is0° position, make the position of the take-up roller at the position where the turning radius of the take-up cam is the smallest
4.3.2 The working principle of the coiling device
The crimping device has a self-adjusting function, when the net is rolled on the roll to gradually increase its diameter, resulting in an increase in the amount of winding.
When, the compensation roller will act, through the connecting rod system, so that the take-up volume is always consistent, the principle is shown in the figure7shown.
4.3.3 Adjustment of coiling device
The size of the take-up depends on the density of the fabric. Its fabric density is adjusted by adjusting the take-up pin in the take-up rocker
The upper and lower positions of the card are realized.
When the fabric density is too thin. When the density of the fabric is too dense, the coiling and selling are adjusted downward.
When a certain set of gears is used and the required winding amount cannot be achieved by adjusting the position of the winding pin, the gears must be replaced.
Group, re-wheel
4.4 Send-off device
Warp feeding unit
4.4.1 Installation position of the send-off cam
The crankshaft angle is180° position, make the position of the let-off roller at the position where the radius of rotation of the let-off cam is the smallest,
4.4.2 The working principle of the let-off device
The let-off device is the active sending out of the warp thread wrapped around the warp shaft. The change in the amount of send-off due to the decrease in the diameter of the beam,
The rotation speed of the beam shaft will be automatically adjusted through the action of the tension roller and the connecting rod system, so that the amount of let-off is always consistent,
4.4.3 Adjustment of the send-off device
In the process of weaving the loom, in principle, the amount of the let-off and the amount of the roll-up are consistent, by adjusting the pin in the let-off rocker.
Up and down position to achieve.
When the send-off is faster than the coiling, the send-off is sold up; when the send-off is slower than the coiling, the send-off is sold down.
in the normal operation of the loom, the weight rod in principle remains stable. If the weight lever tends to the up state, adjust it downward.
Send to distribution; if the weight lever tends to be in a downward state, adjust upward to send to distribution,In addition, weaving a certain density of the net, is by adjusting the amount of winding and the amount of feed to achieve the feed. When a certain set of gears is used,When the required amount of delivery cannot be achieved by adjusting the delivery distribution, the gear set needs to be replaced and the wheels need to be re-matched.
4.5 Rapier movement and adjustment
4.5.1 Two extreme positions of the rapier: the extreme position of the rapier head entering the mesh surface is to leave the mesh surface.30mmThe limit position of the rapier head through the mesh surface is to leave the mesh surface.60mm
4.5.2 The adjustment of the rapier movement is achieved by adjusting the position of the pin on the sector gear.
When it is necessary to increase the amount of movement of the rapier, move the pin toATo adjust; When it is necessary to reduce the amount of movement of the rapier, put the pin
SubwayBTo tune
4.5.3 The adjustment of the limit position of the rapier is realized by adjusting the length of the screw.
When the rapier crosses the limit position in the forward direction, adjust the screw upward; when the rapier is not in place in the forward direction, adjust the screw to the short direction.
4.5.4 Open Roller Adjustment
The time at which the weft thread is disengaged from the rapier is determined by the position of the open roller.
The installation position of the open roller, I .e. the distance between it and the effective net surface, can be considered according to the strength of the wire. Generally speaking, when weaving high-strength wires, the effective mesh distance of the open roller is larger, and when weaving low-strength wires, the effective mesh distance of the open roller is smaller. The user may decide according to the condition of the fabric.The compression of the open roller to the rapier should not be too large, as long as the line can be loosened, otherwise the rapier and steel buckle will be damaged. The size of its compression is adjusted by adjusting the relative position of the open roller and the rapier.
4.6 Weft thread supply and adjustment
4.6.1 The weft thread supply is realized by the coordinated action of the rapier lead wire and the weft clamping and cutting.
The weft clamping device shall be suitable for clamping the weft thread. Too loose will affect the quality of the mesh surface so that the lead cannot be normal. Too tight will cause frequent weft breakage and cannot work normally.
When the weft clamping device is too loose, turn the spring push rod to adjust the wire sheet forward; when the weft clamping device is too tight, turn the spring push rod to adjust the wire sheet backward
4.6.2 When the cutter of the weft clamping device is closed, the cutterAand knivesBGuarantee1mmThe amount of bite. If not, adjust the screw.Ato adjust the toolBThe high and low position
4.6.3 Adjust the relative position of the weft card and the impactor, that is, the relative position of the tool cam and the impactor, so that the toolAand knivesBThe opening amount is adjusted to the appropriate range.
Adjust the weft and impactor to align the cutter cam and impactor.
When adjusting the high and low position of the impactor, pay attention to ensure the clearance between the impactor and the front end of the cutter cam.0.5mm
4.6.4 At work, the toolAWhen it is opened to the maximum limit state, the tool cam should have a movable margin, generally not less1mm

Mechanical processing industry knowledge-milling machine
Earlier we introduced lathes and boring machines. Today we will introduce milling machines to you. We hope that we can better understand the machining industry and some historical stories of machining. In the 19th century, the British invented boring machines and planers for the needs of the industrial revolution such as steam engines, while the Americans devoted their attention to the invention of milling machines in order to produce a large number of weapons. Milling machine is a kind of machine with different shapes of milling cutter, it can cut a special shape of the workpiece, such as spiral groove, gear and so on. As early as 1664, the British scientist Hooke relied on a rotating circular tool to create a machine for cutting, which can be regarded as the original milling machine,
