Description

Film weaving machine

Technical Field

The utility model belongs to the technical field of the film weaving machine, concretely relates to film weaving machine that woof can supply with in succession, the efficiency that the film was woven can further be improved to the continuous supply of woof.

Background

The warp and weft in the form of tape is used to make the engineering have high performance, but the warp without tension is supplied in the weaving process, the unreeling shaft is a common fixed support, and a plurality of tape rolls with different roll diameters are placed on the same fixed support, the design can adapt to different types of tape materials, and avoids the shearing and deformation or easy aggregation of the tapes, especially the fiber tapes, but when the designed woven tapes are ultra-high molecular weight polyethylene films with relatively thin thickness, the warp tapes at the shuttle mouth cannot be completely flattened in a tension-free state, so that the weft insertion mechanism cannot normally enter the shuttle mouth, the quality of the fabric and the normal operation of the production are influenced, and the warp supplying device for supplying the warp without tension with constant length in the design has a complex structure, and is not beneficial to the stable and efficient operation of a weaving machine.

When the production method is used for spinning the ultra-high molecular weight polyethylene film, the method is not satisfactory in terms of labor amount, time consumption and failure rate and product quality, and is only used for fixed support of unreeling, so that the situation that long-time parking is caused due to too long material changing time is caused sometimes.

CN103429803B describes a warp releasing device, which supplies warp for opening and taking-up and withdraws warp for closing shed through a movable contact surface of a rolling component, and this device has the advantages of measuring and controlling warp for opening shed and taking-up operation without clamping warp, overcoming the problems of warp tape sliding, fiber breaking, deformation caused by indentation, etc., but when the device is used for thinner ultra-high molecular weight polyethylene film warp, the warp tape may have inconsistent tightness due to no tension or small tension, which may result in abnormal weft insertion, and at the same time, may affect the flatness of the fabric.

The existing weft insertion device of the textile machine needs to return to the original point after weft insertion, the textile machine can open the next shed, the decomposition action of the textile process is too much (the action which can be executed simultaneously is less, the time is wasted), the supply of weft yarn is discontinuous, and the textile efficiency is low.

The quality of products is seriously influenced by the above conditions, the production efficiency is reduced, the development of production and equipment modernization is restricted, and the demand for developing a new film warp yarn supply device which can improve the product quality and the labor efficiency and can reduce the labor intensity for production by technical personnel in the field is urgently needed.

The base 16 is arranged on the annular slide rail 12 in a sliding manner and used for bearing the upper clamping plate 17 and the lower clamping plate 18 to move on the annular slide rail 12; the surface of the upper clamping plate 17 opposite to the lower clamping plate 18 is provided with a rubber/silica gel coating which is used for preventing slipping when clamping weft yarns; the upper clamping plate 17 is made of a permanent magnet, preferably rubidium magnet in the present embodiment, or a magnet is disposed and fixed on the upper surface of the upper clamping plate 17, and the lower clamping plate 18 is made of a non-metal material such as polypropylene, polytetrafluoroethylene, nylon, or the like.

The corresponding ends of the first section electromagnet 14 and the second section electromagnet 15 are respectively arranged corresponding to the output end of the conveyor belt 11 and the feeding section of the press roller 1, wherein the feeding section of the press roller 1 is the distance between the third guide roller 20 and the press roller 1.

During the control operation, the weaving process of the film weaving machine comprises the following steps:

the coil stock providing warp yarn thin films are arranged on the iron radial unwinding rollers 6 in the first unwinding group and the second unwinding group; clamping grooves (not shown in the figure) are respectively arranged below the first electromagnet 3 and the second electromagnet 4, wherein the second electromagnet 4 descends through an air cylinder 21 to adsorb an iron radial unwinding roller 6 with a warp film in a second unwinding group correspondingly arranged below and lifts through the air cylinder 21 to form a shed, and the air cylinder 21 can be equivalently replaced by other lifting equipment, such as an oil cylinder, a guide rail and the like;

meanwhile, the grippers 13a opposite to the weft yarn on both sides move to both sides of the output end of the conveyor belt 11, that is, in the process that the grippers 13a move on the annular slide rail 12 and transition from the second section of electromagnet 15 to the position below the first section of electromagnet 14, the grippers 13a just switch from an open state to a closed gripping state, so that the edges of both sides of the fixed-length weft yarn on the output end of the conveyor belt 11 are gripped;

then, the annular slide rail 12 and the first section of electromagnet 14 on the annular slide rail start to clamp fixed-length weft yarns and move, the weft yarns transversely pass through a slit between third guide rollers 20 arranged up and down and then are sent to a feeding section of the press roller 1, and then in the process that the yarn clamps 13a on the two sides move on the annular slide rail 12 and transition from the first section of electromagnet 14 to the position below the second section of electromagnet 15, the yarn clamps 13a are just switched from a closed clamping state to an open state, so that the weft yarns are released; here, the third guide roller 20 arranged up and down functions to: after the weft yarn passes through the third guide roller 20, the compression roller 1 feeds the weft yarn and the warp yarn into a certain length (the feeding length is equal to the width of the weft yarn) in the same-direction winding direction, meanwhile, the winding roller 2 rotates to wind and wind the curled fabric, and meanwhile, the existing shed can be closed to open the next shed, so that the time is saved, the efficiency is improved), namely, the three actions of feeding, winding and shedding can be carried out simultaneously; if the third guide roller 20 is not arranged, the sequence is changed into that weft yarn firstly reaches a feeding section of the press roller 1, then the press roller 1 feeds the weft yarn and warp yarn in the same winding direction for a certain length (the feeding length is equal to the width of the weft yarn), meanwhile, the winding roller 2 rotates to wind the curled fabric, and finally, the existing shed is closed to open the next shed, namely, the feeding and winding actions are still carried out simultaneously, but the shedding action is carried out after the shedding action, and the feeding and winding actions cannot be carried out simultaneously.

Meanwhile, the compression roller 1 feeds the weft yarns and the warp yarns into a certain length (the feeding length is equal to the weft yarn width) in the same winding direction, and the winding roller 2 rotates to wind the curled fabric.

At the moment, the second electromagnet 4 puts the iron radial unwinding roller 6 with warp films in the second unwinding group which is correspondingly adsorbed below back to the original position in the shell 5; meanwhile, the first electromagnet 3 absorbs and lifts the iron radial unreeling roller 6 with warp films in the first unreeling group correspondingly arranged below to form a shed again;

then, in the same manner as described above, when the gripper 13a is just switched from the closed gripping state to the open state to release the weft, the gripper 13b just continuously grips the next weft of a fixed length and moves forward, feeds the weft of the fixed length into the feeding section of the press roller 1 and releases the weft, and simultaneously, the press roller 1 feeds the weft and the warp in the same winding direction for a certain length (the feeding length is equal to the weft width), and synchronously, the wind-up roller 2 winds up the curled fabric;

at the moment, the second electromagnet 4 absorbs and lifts the iron radial unwinding roller 6 with the warp yarn film in the second unwinding group which is correspondingly absorbed below; at the same time, the first electromagnet 3 replaces the iron radial unwinding roller 6 with the warp film in the first unwinding group back into the housing 5, i.e. again alternately to form the shed.

Then, in the same way as above, the fixed-length weft yarns conveyed by the output end of the clamping conveyor belt 11 are clamped by the yarn clamping device 13c to move forwards, the fixed-length weft yarns are conveyed to the feeding section of the press roller 1 and then are loosened, meanwhile, the press roller 1 feeds the weft yarns and the warp yarns into a certain length (the feeding length is equal to the width of the weft yarns) in the same winding direction, and synchronously, the winding roller 2 winds the curled fabric;

synchronously, iron radial unwinding rollers 6 with warp films in the first unwinding group and the second unwinding group respectively corresponding to the lower parts of the first electromagnet 3 and the second electromagnet 4 are alternately formed into sheds again. I.e. forming an endless continuous weave.

Therefore, the fact that the simultaneous implementation of inserting and beating-up actions, entering the compression roller 1 and winding is not influenced, the continuous formation of shed opening can be achieved, in general, the gripper circularly clamps the weft with fixed length to continuously supply the weft to be inserted for weaving, and the film weaving efficiency is effectively improved.

The second embodiment: the difference from the first embodiment is that the insertion device can also be implemented by replacing the endless slide rail 12 with a linear slide rail 23 as shown in fig. 1 and 7, wherein the linear slide rail 23 is arranged between the output end of the conveyor belt 11 and the feeding end of the compression roller 1, a gripping device 22 is arranged inside the linear slide rail 23, the gripping device 22 is slidably arranged on the linear slide rail 23 for reciprocating motion, the gripping device 22 is a suction cup or a clip, in this embodiment, the third guide roller 20 is not provided, and the gripping device 22 is a clip.

Two opposite clamps in the weft insertion device simultaneously clamp two sides of the fixed-length weft yarn, then the fixed-length weft yarn is fed into a formed shed through a linear sliding rail 23, then the clamps at the two edges are loosened and return to clamp the next fixed-length weft yarn again, and the corresponding warp yarn films alternately form a shed again; namely, the arranged clamp or the sucking disc is used for clamping and adsorbing the fixed-length weft yarn and moving the fixed-length weft yarn to a shed to finish the actions of inserting and beating up. In the process of returning to clamp and taking off the next weft yarn, the clamps at the two edges in the weft insertion device do not influence the first electromagnet 3 and the second electromagnet 4 to alternately adsorb the corresponding warp yarns, namely do not influence the formation of the next shed, so that the next shed can be formed simultaneously, the next weft yarn can be rapidly clamped and inserted into the newly formed shed, and the production efficiency is improved;

the foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the principles of this invention. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
