Description

Film textile machine

Technical Field

The invention belongs to the technical field of film spinning machines, and particularly relates to a film spinning machine with a weft yarn capable of being continuously supplied, wherein the continuous supply of the weft yarn can further improve the film weaving efficiency.

Background

In CN101120128B and CN101120129B a new method and apparatus for weaving tape-like warps and wefts is described, which weaving process is capable of processing different types of tape materials to make fabric materials for various technical applications, such as ballistic protection, conveyor belts, liquid discharge panels, etc., but also not only for composite applications. The use of warp and weft yarns in the form of tapes gives engineering with never higher performance, but the tension-free warp yarn is fed in the weaving process, the unwinding shaft is a common fixed support, and a plurality of rolls of different diameters are placed on the same fixed support, although the design can adapt to different types of tape materials, avoiding shearing and deformation or easy aggregation of tapes, especially fiber tapes, but the design woven tapes are thin ultra-high molecular weight polyethylene films, warp tapes at the shed cannot be completely flattened in a tension-free state, which results in that the weft insertion mechanism cannot enter the shed normally, affecting the quality of the fabric and the normal running of the production, and the warp yarn feeding device for feeding tension-free warp yarn of constant length in the design is complex in structure and is unfavorable for the stable and efficient running of the weaving machine.

When the production method is used for spinning the ultra-high molecular weight polyethylene film, the production method is unsatisfactory in terms of labor capacity, time consumption and failure rate and product quality, and only is used for fixed support of unreeling, so that the condition that long-time stopping is caused when the material is changed occurs.

In the prior art, a textile machine using a slip shaft as a unreeling shaft has similar defects, and when the slip shaft is used as the unreeling shaft, a plurality of reels of material are put on one slip shaft, and only one reel diameter sensor can be installed, because in actual production, the diameters of the reels are difficult to be completely consistent, and the tension of the reels on the same slip shaft is inconsistent.

In CN103429803B a warp release device is described, which supplies warp yarn for opening and reeling through a movable contact surface of a rolling member and also withdraws warp yarn for closing the shed, which has the advantage that the control of warp yarn for opening and reeling operations can be measured without clamping warp yarn, overcoming the problems of slipping of the warp tape, fiber breakage, deformation caused by indentation etc., but when the device is used for thinner ultra high molecular weight polyethylene film warp yarn, non-uniform tightness of the warp tape due to no tension or small tension may occur, possibly resulting in non-normal weft insertion and also affecting 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 actions of decomposition in the spinning process are too many (namely, the actions which can be simultaneously executed are little, time is wasted), the weft yarn is fed discontinuously, and the spinning efficiency is low.

The above conditions seriously affect the quality of the product, and meanwhile, the production efficiency is reduced, and the development of modernization of production and equipment is restricted, so that a new film warp yarn supply device capable of improving the quality and labor efficiency of the product and reducing the labor intensity is required to be developed by those skilled in the art for production.

The base 16 is slidably arranged on the annular slide rail 12 and is 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 for skid resistance when clamping weft yarns; the upper clamping plate 17 is made of a permanent magnet or a piece of magnet is arranged and fixed on the upper clamping plate 17, in this embodiment, the permanent magnet is preferably a rubidium magnet, and the lower clamping plate 18 is made of a nonmetallic material such as polypropylene, polytetrafluoroethylene, nylon, etc.

The three grippers 13 include

Here, as shown in fig. 1 and fig. 5, the upper clamping plate 17 is correspondingly matched with the first section electromagnet 14 and the second section electromagnet 15 on the annular slide rail 12, so that the clamping device 13 is controlled to be opened or closed, that is, by utilizing the principle that like poles of the magnets repel each other and unlike poles attract each other, in this embodiment, the magnetic pole under the first section electromagnet 14 is N-level, the magnetic pole under the second section electromagnet 15 is S-level, and when each clamping device 13 moves under the first section electromagnet, the upper clamping plate 17 moves downwards until the upper clamping plate 17 contacts with the lower clamping plate 18 correspondingly due to the like poles repel each other, and the upper clamping plate 17 contacts with the lower clamping plate 18 just enough to clamp the edge of the weft yarn, and then moves forwards until the lower part reaches the tail end of the first section electromagnet 14 and the lower part of the initial end of the second section electromagnet 15, because the magnetic pole under the second section electromagnet 15 is S-level, when encountering the upper clamping plate 17 with the upper level N-level, the upper clamping plate 17 moves upwards to clamp the adsorption plate 17, thereby releasing the edge of the weft yarn. The 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 refers to the distance between the third guide roller 20 and the press roller 1.

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

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

meanwhile, the grippers 13a opposite to the two sides of the weft yarn move to the two sides of the output end of the conveyor belt 11, namely, the grippers 13a just change from an open state to a closed clamping state in the process of transition from the second section electromagnet 15 to the lower part of the first section electromagnet 14 when the grippers 13a move on the annular slide rail 12, so that the edges of the two sides of the weft yarn with the fixed length of the output end of the conveyor belt 11 are clamped;

after that, the fixed-length weft yarn starts to be clamped by the annular slide rail 12 and the first section electromagnet 14 thereon, and the weft yarn is fed into the feeding section of the compression roller 1 after traversing the slit between the third guide rollers 20 arranged up and down, and then the two side yarn clamps 13a are moved on the annular slide rail 12 in the process of transition from the first section electromagnet 14 to the position below the second section electromagnet 15, the clamp 13a is just switched from the closed clamping state to the open state, so that the weft yarn is loosened; here, the third guide roller 20 disposed up and down functions as: after the weft yarn passes through the third guide roller 20, the compression roller 1 feeds the weft yarn and the warp yarn to a certain length (the feeding length is equal to the width of the weft yarn) in the winding direction, meanwhile, the winding roller 2 rotates to 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, three actions of feeding, winding and shed opening can be simultaneously carried out; if the third guide roller 20 is not provided, the sequence becomes that the weft yarn reaches the feeding section of the press roller 1 first, then the press roller 1 feeds the weft yarn and the warp yarn together in the 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 performed simultaneously, but the shedding actions are not performed simultaneously.

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

At the moment, the second electromagnet 4 returns the iron radial unreeling roller 6 with the warp film in the second unreeling group which is correspondingly adsorbed below to the original position in the shell 5; simultaneously, the first electromagnet 3 adsorbs and lifts an iron radial unreeling roller 6 with a warp film in a 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 yarn, the gripper 13b just continuously grips down a certain length of weft yarn and moves forward, and releases the weft yarn after feeding the certain length of weft yarn into the feeding section of the press roller 1, and simultaneously, the press roller 1 feeds the weft yarn and the warp yarn together in the winding direction for a certain length (the feeding length is equal to the width of the weft yarn), and the winding roller 2 winds the curled fabric simultaneously;

at the moment, the second electromagnet 4 adsorbs and lifts the iron radial unreeling roller 6 with the warp film in the second unreeling group which is adsorbed correspondingly below; at the same time, the first electromagnet 3 puts the iron radial unwind roller 6 with warp film in the first unwind group back into position in the housing 5, i.e. alternately again forming a shed.

Then, in the same manner as described above, the yarn gripper 13c grips the fixed-length weft yarn conveyed from the output end of the conveyor belt 11, moves forward, and releases the weft yarn after feeding the fixed-length weft yarn into the feeding section of the press roller 1, and simultaneously, the press roller 1 feeds the weft yarn and the warp yarn together in the winding direction for a certain length (the feeding length is equal to the width of the weft yarn), and the winding roller 2 winds the curled fabric synchronously;

synchronously, the iron radial unreeling rollers 6 with warp films in the first unreeling group and the second unreeling group, which are respectively corresponding below the first electromagnet 3 and the second electromagnet 4, alternately form sheds again. I.e. form endless continuous weaves.

Therefore, the continuous formation of the shed can be realized simultaneously without affecting the simultaneous execution of the insertion and beating-up actions entering the compression roller 1 and winding, and the gripper circularly clamps the fixed-length weft yarn to continuously feed the insertion for knitting, so that the film knitting efficiency is effectively improved.

Embodiment two: the difference from the first embodiment is that the insertion device can also be implemented by replacing the endless track 12 with a linear track 23 as shown in fig. 1 and 7, wherein the linear track 23 is arranged between the output end of the conveyor belt 11 and the feeding end of the press roll 1, the inside of the linear track 23 is provided with a gripping device 22, the gripping device 22 is slidably arranged on the linear track 23 for reciprocating movement, the gripping device 22 is a suction cup or a clip, in this embodiment, the third guide roll 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 the linear sliding rail 23, then the clamps at the two edges are loosened and returned to clamp the next fixed-length weft yarn again, and the corresponding warp films alternately form the shed again; the clamp or the sucker is used for clamping and sucking the fixed-length weft yarn and moving to the shed to complete the weft insertion and beating-up actions. In this case, in the process of returning the clips at two edges of the weft insertion device to clip and take down a weft yarn, the first electromagnet 3 and the second electromagnet 4 are not affected to alternately adsorb the corresponding warp yarns, that is, the formation of the next shed is not affected, so that the next shed can be formed simultaneously, and the rapid clipping and insertion of the next weft yarn and the newly formed shed can be performed, thereby improving the production efficiency;

the foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by a person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
