Description

Magnetic force loom

The present invention relates to a kind of novel shuttleless loom-magnetic force loom.

Multi-form shuttleless looms such as the air-jet loom, water jet looms, Rapier looms, gripper shuttle loom that come out the present age, cost an arm and a leg, need supporting a series of auxiliary equipment simultaneously, as air compression system, water system etc. at machining accuracy height, complex structure.A large amount of introductions are subjected to the restriction of foreign exchange and accessory again, and technical management also is difficult to adapt to.Digestion is imitated, be subjected to the restriction of material, precision, supporting electronic devices and components again, thereby mass production capabilities is poor, and the manufacturing cost height is so limited the large-scale popularization application.

The objective of the invention is to create a kind of novel no shuttle weft thread-leading machine-magnetic force loom.Make it to be different from the other forms of shuttleless loom that has come out, more be different from traditional fly-shuttle loom.Especially use the heavy magnetic force loom of development and design of the present invention, not limited by the thick and heavy and fabric width of fabric, its structure is also more simple.Make it more help China's textile industry progress at aspects such as varietal adaptation, economy, develop and apply and catch up with world development trends at new machine.

The present invention is achieved in that the magnetic weft insertion mechanism of magnetic force loom, be by transmissions such as synchromesh gear and synchromesh gear band and bevel gear pairs, cover Magnetic force tracting device by setting-in on it, utilize magnetic force to be driving force, weft carrier is led in the shuttle plate in the groove formula, back and forth roll or slide through shed open.The Magnetic force tracting device is that the elements such as bearing that the traction body made by strong magnetic permanent-magnet material and unmagnetized material are made constitute.It is to lead the shuttle passage with what the unmagnetized material was made that the groove formula is led the shuttle plate, and there is running rail its underpart, and control Magnetic force tracting device along continuous straight runs reciprocating motion track is not because of the stressed influence of fluctuations magnetically-actuated of synchromesh gear band transmission effect.Its top has a spill to lead the shuttle passage, and weft yarn operation by the weft carrier clamping on this passage.Since weft carrier very light (about 30～50g), in running, be subjected to magnetically-actuated effect and rubbing action, can change running orbit, the injury warp thread.Be control weft carrier running orbit, weft carrier is back and forth operation in this passage.The effect that the groove formula is led the shuttle plate is when the reciprocal wefting insertion of weft carrier passes through shed open, and warp thread is implanted in the groove, and weft yarn is laid in the middle of the warp thread.Lead shuttle board slot ditch density and be complementary with reed density, warp thread must with lead the shuttle Board position match weft carrier along lead the shuttle passage when back and forth moving and warp thread do not have relative friction.The groove formula lead the shuttle plate up and down the distance between two tracks heal better little, in order to avoid influence the magnetically-actuated effect.The traverse of weft carrier is to quicken synchronously and deceleration with reciprocating Magnetic force tracting device.The acceleration of weft carrier and deceleration are to be decided by the Magnetic force tracting device reciprocating motion speed of design.

Through thread-carrier, weft tension device, weft accumulator, yarn feeder, sedimentation bar etc., the weft carrier clamping is transferred in the weft yarn end that unwinding on the weft yarn bobbin is got off, driven by the Magnetic force tracting device and dragged whole shed open, and in clamping and the transmission in turn of loom bilateral symmetry ground.Under auxiliary bodies such as edge-folding mechanism cooperate, finish the weaving process process of magnetic force loom.

When magnetic force loom was whenever knitted a latitude, the withdrawal speed of weft yarn bobbin and filling insertion rate equaled the fltting speed of weft carrier.The unwinding of weft yarn is only a certain instantaneous controlled, is firmly clamping when promptly guiding weft yarn, and weft yarn must come loose before weft carrier is finished its stroke.By lay sword the weft yarn of introducing is pushed to fell at last, in pushing the fell process to, the groove formula is led the shuttle plate and is relied on the lay sword swing to move back to the cloth cover below, weft yarn and warp thread is interweaved form the fabric that adheres to specification.

Principle of the present invention and structure are drawn by following examples and accompanying drawing.

Fig. 1 is the weaving process process of magnetic force loom.

Fig. 2 is the magnetic weft insertion mechanism driving system of magnetic force loom.

The weaving process process of magnetic force loom is as described below:

Shown in Figure 1, weft yarn (16) is drawn on weft yarn bobbin (15), sends into yarn feeder (12) through thread-carrier (17), weft tension device (13), weft accumulator (14).Yarn feeder must be delivered to the end of weft yarn near the selvedge place before each wefting insertion.Weft yarn (9) is to introduce fell from left to right, and weft yarn (10) is to introduce fell from right to left.Before weft carrier (1) moved, to moving, sedimentation bar (8) was pressed b to moving to yarn feeder (12) a, makes weft yarn be in the groove formula and leads leading on the shuttle passage of shuttle plate (5) along a.

Weft carrier by the Magnetic force tracting device (2) of setting-in it on, is led under the shuttle plate in the gathering sill in the groove formula in the magnetic weft insertion mechanism that synchromesh gear (4) and synchromesh gear (3) etc. are formed, and leans on bearing (2) a of setting-in on the Magnetic force tracting device to move along its groove.Under magnetically-actuated, make weft carrier by c to moving.At this moment weft yarn is held by yarn clipping sheet (1) a on the weft carrier, is round and drags shed open, and in the X1 distance, weft yarn is introduced in the wedge-like slit, and the yarn clipping sheet firmly grips weft yarn under the weft carrier spring action.

When weft carrier continues towards c when mobile, filling space in tow is straightened, and when gripping weft yarn, cuts off with the edge of a knife of its cutting edge of a knife or a sword power, makes weft yarn be passed through shed open in tow.When weft carrier (shown in weft carrier position, Fig. 1 right side) when the outlet side of loom leaves warp thread (18), the push rod on the weft carrier (1) b and spacing rotor (6) a that is fixed on the loom bump against, and weft yarn comes loose from the yarn clipping sheet at a distance of the X2 place leaving selvedge.

The weft yarn that weft carrier walk to be under not with the state of weft yarn its whole process, damped device (11) are introduced spacing this moment freely is among the shed open, is beaten to fell with reed (19) by lay sword (20).When reed was beaten to fell, the groove formula was led the shuttle plate under the lay sword swing, moved back to the cloth cover below, became under the cooperation of limit mechanism to form selvedge at edge-folding mechanism (7) or other.

Because of the structure at weft carrier two ends is symmetrical, weft carrier in the bilateral symmetry ground clamping in turn of loom, transmit weft yarn and introduce fell, weft yarn and warp thread are interweaved.And in other motions, as opening, beat up, batch, motion such as the warp let-off and protective device cooperate down, forms the fabric that adheres to specification.

The magnetic weft insertion mechanism driving system of magnetic force loom is as described below:

Shown in Figure 2, be to adopt long lay sword magnetic weft insertion mechanism driving system, warp thread through the back rest (21), warp stop frame (22), after harness eye (23), preceding harness eye (24), enter reed (1), under harness motion, form shed open.Weft carrier (3) is under the groove formula is led Magnetic force tracting device (4) magnetically-actuated under the shuttle plate (2), through synchromesh gear (7), synchromesh gear band (8), bevel gear pair (9), synchromesh gear band (10), synchromesh gear (20), escapement (11), connecting rod transmissions such as (19).Escapement is directly installed on the lay sword (25), swings with lay sword.The outside of escapement have one radially elongated slot adorn a mandrel, link to each other with the collar (14) on being enclosed within eccentric wheel (13) through connecting rod (12).Eccentric wheel by main shaft (17) through synchromesh gear (15), synchromesh gear band (16), synchromesh gear (18), connecting rod (19) transmission.

Loom is in revolution, and escapement is on the one hand with the lay sword swing, and when doing the radius of clean-up increase of swing, escapement with respect to lay sword around the axle center of self again on the other hand, the traverse of weft carrier reduces, and can regulate cloth fabric width degree.The stroke of weft carrier is the resultant motion that swinging back and forth of causing of the swing by lay sword and eccentric wheel make the swing that escapement produces.

Weft carrier is pulled weft yarn into shed open, squeezes into fell by reed (1), and when reed was squeezed into fell, the groove formula was led the shuttle plate is flapped toward cloth cover (6) through brest beams (5) below (being flapped toward shown in the II position by Fig. 2 I position).

The magnetic weft insertion mechanism of magnetic force loom also can adopt short lay sword weft insertion device, and its difference only is the escapement kink on rocker, and with the lay sword swing, other parts are not contained on the lay sword, swing with lay sword.The stroke of weft carrier makes from the motion of escapement with from the synthetic compound motion of the motion of lay sword swing.
