Description

Technical Field

[0001] The invention relates to the field of water jet looms, in particular to a water jet loom with adjustable weaving width. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of the weft yarn by water jet insertion is greater than that by air jet insertion, and the diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the water jet weft consumes less energy and has the lowest noise.

[0003] For example, the invention patent with publication number CN111560695B discloses a water jet and air jet dual-purpose loom, which belongs to the technical field of shuttleless looms, which includes a frame, a feeding mechanism for loading warp threads is arranged at one end of the frame, a splitting mechanism for grouping warp threads is arranged at a position of the frame corresponding to the side of the warp support, and a beating-up mechanism for beating-up weft threads is arranged at a position of the frame corresponding to the splitting mechanism away from the feeding mechanism; an air jet mechanism and a water jet mechanism for threading weft threads are arranged at a position between the splitting mechanism and the beating-up mechanism on one side of the frame, and a conversion component for switching the air jet mechanism and the water jet mechanism is arranged at a position of the frame close to the air jet mechanism and the water jet mechanism; a lead-in mechanism for loading weft threads is arranged at a position of the frame corresponding to the air jet mechanism away from the frame.

[0004] With regard to the above case, in the prior art, in the process of weaving using a water jet loom, the weft is ejected by the water jet mechanism and passes through the warp. In this process, as the moving distance of the weft increases, it moves away from the jet mechanism, so that the jet force on the weft is reduced. Under the action of gravity, the weft will sag to a certain extent.

[0005] In the actual production process, it is often necessary to produce fabrics of different widths. If the fabric width is large, it is easy for the weft thread to not pass completely, making it easy for the weft thread to be entangled with the warp thread on the path.

When the cloth width is larger, the angles of the upper and lower warp threads are larger, and vice versa, which is conducive to the smooth passage of the weft threads through the warp threads and reduces the problem of entanglement between the weft threads and the warp threads on the path.

[0047] 2. The present invention sets a driving disk, and in the process of the upper mounting frame and the lower mounting frame sliding up and down, the upper lead rod and the lower lead rod drive several warp threads to perform an up and down staggered movement, so that the weft thread sprayed by the water nozzle can be clamped by the two warp threads, which is beneficial to improve the stability of the connection between the warp thread and the weft thread, avoid the weft thread from falling off, and improve the quality of the cloth.

[0049] Fourth, the present invention arranges a compression shell and a piston so that the water nozzle can adaptively adjust the spray speed according to the width of the cloth. When the cloth width is larger, the spray speed of the water nozzle increases, and the spray force on the weft line increases, so that the weft line can be sprayed to a farther place. Conversely, the smaller the speed, the further avoids the problem of entanglement between the weft line and the warp line on the path. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] Four sliding frames 5, the four sliding frames 5 are symmetrically fixedly connected to the grooves on both sides of the base 1 corresponding to the upper mounting frame 2 and the lower mounting frame 3 respectively, and the upper and lower ends of the sliding frames 5 are symmetrically slidably connected to the limit housing 6, and the limit housing 6 is slidably connected to the side grooves of the base 1;

[0064] A push adjustment mechanism, which is used to push the two limit shells 6 to slide, so that the two limit shells 6 move away from or closer to each other;

[0065] Four push frames 7, the four push frames 7 are symmetrically fixedly connected to the side walls of the upper mounting frame 2 and the lower mounting frame 3;

[0066] Four drive disks 8, the four drive disks 8 are symmetrically rotatably connected to the side wall of the base 1 corresponding to the positions of the upper mounting frame 2 and the lower mounting frame 3 respectively, and a straight groove 801 is provided on the side wall of the drive disk 8, a push pin 9 is slidably connected in the straight groove 801, and the push pin 9 is slidably connected in the push frame 7, and a sliding adjustment component is provided in the straight groove 801, and the sliding adjustment component is used to slidably adjust the position of the push pin 9 in the straight groove 801;

[0067] In the first embodiment of the sliding adjustment assembly, a first spring 10 is fixedly connected between the push pin 9 and the straight slot 801;

[0068] A water spray nozzle 12, the water spray nozzle 12 is fixedly connected to the outer wall of the base 1, and a weft line 13 is inserted into the water spray nozzle 12;

[0069] Specifically, in the prior art, during the weaving process using a water jet loom, the weft is ejected by the water jet mechanism and passes through the warp 4. During this process, the weft 13 moves away from the jet mechanism as the moving distance increases, so that the jet force on the weft 13 decreases. Under the action of gravity, the weft 13 sags.

[0070] There are the following disadvantages: in the actual production process, it is often necessary to produce fabrics of different widths. If the fabric width is large, it is easy for the weft line 13 to not pass completely, so that the weft line 13 is easy to be entangled with the warp line 4 on the path;

[0071] This technical solution can solve the above problems, and the specific operations are as follows:

[0072] When the cloth width is large, the push adjustment mechanism is activated to make the two limit shells 6 move away from each other, otherwise they move closer to each other;

[0073] When the two limiting shells 6 move away from each other, the use length of the sliding frame 5 can be extended, so that the sliding distance of the upper mounting frame 2 and the lower mounting frame 3 is increased;

[0074] In addition, in the process of the two limiting shells 6 moving away from each other, under the elastic force of the first spring 10, the two push pins 9 on the upper mounting frame 2 move upward along the straight groove 801, and the two push pins 9 on the lower mounting frame 3 move downward, so that the upper mounting frame 2 moves upward and the lower mounting frame 3 moves downward, thereby increasing the angle between the upper and lower warps 4, making the two warps 4 away from the weft 13, and increasing the distance that the weft 13 can sag, which is conducive to avoiding the problem that the weft 13 is easily entangled with the warp 4 on the path due to the large width of the cloth;

[0075] After the adjustment is completed, the driving disk 8 is rotated by the first motor on the outer side of the machine base 1. During the rotation of the driving disk 8, the pushing pin 9 slides along the inside of the pushing frame 7, and the pushing frame 7 moves up and down, so that the upper mounting frame 2 and the lower mounting frame 3 move up and down, and because the limit shell 6 has been adjusted to move away from each other, the upper mounting frame 2 can move upward to a farther distance, and the lower mounting frame 3 can move downward to a farther distance, thereby increasing the angle between the upper and lower warps 4, so that the two warps 4 are away from the weft 13, and the distance that the weft 13 can sag is increased, which is conducive to the smooth passage of the weft 13 through the warp 4, and reduces the problem of the weft 13 and the warp 4 on the path.

[0076] When the upper mounting frame 2 and the lower mounting frame 3 are respectively limited by the limiting shell 6 and cannot slide, the push pin 9 will slide along the straight groove 801, and then compress the first spring 10, so that the compression elastic force of the first spring 10 increases;

[0077] In addition, during the up and down sliding of the upper mounting frame 2 and the lower mounting frame 3, the upper lead rod 201 and the lower lead rod 301 drive several warp threads 4 to perform an up and down staggered movement, so that the weft threads 13 sprayed by the water nozzle 12 can be clamped by the two warp threads 4, which is beneficial to improve the stability of the connection between the warp threads 4 and the weft threads 13, avoid the weft threads 13 from falling off, and improve the quality of the fabric.

[0078] In the second embodiment of the sliding adjustment assembly, the electric telescopic rod 11 is fixedly connected in the straight groove 801, and the push pin 9 is fixedly connected to the output end of the electric telescopic rod 11;

[0079] Specifically, the position of the push pin 9 is adjusted by pushing the electric telescopic rod 11, so that the upper mounting frame 2 and the lower mounting frame 3 move along different height tracks, and the angles of the upper warp line 4 and the lower warp line 4 can be adjusted according to the width of the cloth.

[0080] As a further embodiment of the present invention, it also includes:

[0081] The beating-up plate 20 is slidably connected to the machine base 1, and a plurality of long grooves 2001 are formed in an array on the side wall of the beating-up plate 20;

[0082] Two second cylinders 21, the two second cylinders 21 are symmetrically fixedly connected to the inner side wall of the base 1, and the telescopic rods of the second cylinders 21 are fixedly connected to the side wall of the beating-up plate 20. The telescopic rods of the second cylinders 21 extend when the two warp threads 4 approach each other, so as to push the beating-up plate 20 to move toward the front end of the base 1, so as to push the weft threads 13 sprayed by the water nozzle 12 and compact them with the warp threads 4;

[0083] The telescopic rod of the second cylinder 21 is retracted when the two warp threads 4 move away from each other, so as to pull the beating-up board 20 away from the front end of the machine base 1, making way for the water nozzle 12 to spray the weft thread 13;

[0084] Specifically, it can be known from the above that in the process of the upper mounting frame 2 and the lower mounting frame 3 moving up and down, the upper warp line 4 and the lower warp line 4 are close to each other, so that the angle between the upper warp line 4 and the lower warp line 4 is gradually reduced to a parallel state, and then the upper mounting frame 2 and the lower mounting frame 3 continue to move, the upper warp line 4 moves to the position of the original lower warp line 4, and the lower warp line 4 moves to the position of the original upper warp line 4. At this time, the two warp lines 4 are away from each other, so that the angle between them increases, and this reciprocating process is performed;

[0085] When the two warp threads 4 approach each other, the telescopic rod of the second cylinder 21 extends to push the beating plate 20 to move toward the front end of the machine base 1, so as to push the weft threads 13 sprayed by the water nozzle 12 and compact them with the warp threads 4;

[0086] The two warp threads 4 retract in the process of moving away from each other to pull the beating-up board 20 away from the front end of the machine base 1 to make way for the water nozzle 12 to spray the weft thread 13.

[0087] As a further embodiment of the present invention, the push adjustment component includes:

[0088] Two first drive plates 14, the two first drive plates 14 are symmetrically slidably connected to the outer wall of the base 1, a first inclined groove 1401 is opened on the outer wall of the first drive plate 14 corresponding to the position of the limit shell 6, two adjacent first inclined grooves 1401 are in an eight-shaped shape, and the outer wall of the limit shell 6 is fixedly connected with a first connecting pin, and the first connecting pin is slidably connected in the first inclined groove 1401 at the corresponding position;

[0089] In the case of the first embodiment of the sliding adjustment assembly, it also includes:

[0090] Two first cylinders, the first cylinders are symmetrically fixedly connected to the outer wall of the base 1, and the telescopic rods of the first cylinders are fixedly connected to the first driving plate 14 at the corresponding position;

[0091] Specifically, by setting the first driving plate 14 and the first cylinder, when the cloth width is large, the first cylinder is started so that the telescopic rod of the first cylinder is extended, thereby pushing the first driving plate 14 to move, so that the two adjacent limiting shells 6 move along the trajectory of the first inclined slot 1401, so that the two limiting shells 6 move away from each other, thereby extending the effective length of the sliding frame 5, so that the sliding distance of the upper mounting frame 2 and the lower mounting frame 3 is increased, and in the process of the two limiting shells 6 moving away from each other, under the elastic force of the first spring 10, the two pushing pins 9 at the position of the upper mounting frame 2 move upward along the straight slot 801, and the two pushing pins 9 at the position of the lower mounting frame 3 move downward, so that the upper mounting frame 2 moves upward, and at the same time the lower mounting frame 3 moves downward, thereby increasing the angle between the upper and lower warp lines 4, so that the two warp lines 4 are away from the weft line 13, and the distance that the weft line 13 can sag is increased, which is conducive to avoiding the problem that the weft line 13 is easily entangled with the warp line 4 on the path due to the large cloth width;

[0092] On the contrary, when the cloth width is small, the telescopic rod of the first cylinder retracts backward, so that the two limit shells 6 are close to each other, and the upper mounting frame 2 and the lower mounting frame 3 are close to each other, thereby reducing the angle between the two warp lines 4, avoiding that the angle between the two warp lines 4 is too large, causing the warp lines 4 to be overly tight, resulting in damage to the warp lines 4.

[0093] As a further embodiment of the present invention, it also includes:

[0094] A take-up roller 18, the take-up roller 18 is rotatably connected to the front end side wall of the end of the base 1, and a distance sensor 19 is provided on the end side wall of the take-up roller 18, and the distance sensor 19 is used to detect the width of the cloth;

[0095] Specifically, by setting a collection roller 18, a second motor is installed on the machine base 1, and the second motor drives the collection roller 18 to rotate to collect the woven fabrics, and by setting a distance sensor 19, the width of the fabrics is detected, so as to calculate the pushing distance of the first cylinder to adapt to the adjustment of different fabrics.

[0096] It should be noted that the warp threads 4 are sequentially introduced into the upper lead rod 201 and the lower lead rod 301 in the order of arrangement, and as the number increases, the edge of the cloth will gradually approach the distance sensor 19.

[0097] As a further embodiment of the present invention, it also includes:

[0100] Specifically, before the first cylinder pushes the first driving plate 14, the clamping block 16 is first disengaged from the limiting groove 1402, and then the first cylinder pushes the first driving plate 14 to move, and then the clamping block 16 is clamped with the upper limit groove 1402 at the corresponding position, which is conducive to observing whether the first driving plate 14 is moved to the specified position, and then it is conducive to identifying whether the angle of the two meridians 4 is adjusted to the specified value.

[0101] As a further embodiment of the present invention, a drainage pool 101 is further included. The drainage pool 101 is opened at the front end of the machine base 1 and is used to store and discharge the water sprayed by the water nozzle 12.

When the piston 23 moves to generate negative pressure in the compression shell 22, the second one-way valve closes, and water in the external water tank is sucked in through the water inlet pipe 2202 and replenished into the compression shell 22.

[0115] The external threaded sleeve 31 is rotatably connected to the outer side wall of the end of the compression shell 22, the movable rod 24 is slidably connected to the external threaded sleeve 31, and the limit block 30 is threadedly connected to the outer side wall of the external threaded sleeve 31;

[0116] A rotation drive mechanism, which is used to drive the external threaded sleeve 31 to rotate so as to adjust the position of the limit block 30;

[0117] The rotary drive mechanism includes:

[0118] A gear 32, the gear 32 is fixedly connected to the end surface of the external threaded sleeve 31;

[0119] A rack 33, the rack 33 is slidably connected to the outer wall of the base 1, and the rack 33 is meshed with the gear 32;

[0120] A second driving plate 34, the second driving plate 34 is fixedly connected to the side wall of the first driving plate 14, a second inclined groove 3401 is opened on the surface of the second driving plate 34, a second connecting pin is fixedly connected to the side wall of the rack 33, and the second connecting pin is slidably connected in the second inclined groove 3401;

[0121] Specifically, in the process of the first cylinder pushing the first driving plate 14, the second driving plate 34 is moved, so that the rack 33 slides along the second inclined groove 3401. Driven by the second inclined groove 3401, the rack 33 moves downward and meshes with the gear 32, so that the gear 32 rotates, and the external threaded sleeve 31 rotates. Under the action of the threaded connection, the limit block 30 moves linearly along the side wall of the base 1, away from the first baffle 25, and the limiting effect on the first baffle 25 is cancelled. At this time, the push rod 28 is in an extruding effect on the third spring 29, and the third spring 29 is compressed. When the limit block 30 cancels the limit on the first baffle 25, the third spring 29 Under the elastic action, the first baffle 25 drives the sliding rod 26 and the second baffle 27 to move toward the limit block 30, so that the movable rod 24 drives the piston 23 to move toward the drain pipe 2201 at the end of the compression shell 22, thereby increasing the compression distance of the piston 23 and increasing the water output of the water nozzle 12. It can be deduced from the above content that the spraying time of the water nozzle 12 is certain, and the water spraying diameter of the water nozzle 12 is also certain. Therefore, when the water output of the water nozzle 12 increases, the spraying speed of the water nozzle 12 increases, and the spraying force on the weft line 13 increases, so that the weft line 13 can be sprayed to a farther place, further avoiding the problem of the weft line 13 being entangled with the warp line 4 on the path.

[0122] The working principle of the present invention is as follows:

[0123] When the cloth width is large, the push adjustment mechanism is activated to make the two limit shells 6 move away from each other, otherwise they move closer to each other;

[0124] When the two limiting shells 6 move away from each other, the use length of the sliding frame 5 can be extended, so that the sliding distance of the upper mounting frame 2 and the lower mounting frame 3 is increased;

[0125] In addition, in the process of the two limiting shells 6 moving away from each other, under the elastic force of the first spring 10, the two push pins 9 on the upper mounting frame 2 move upward along the straight groove 801, and the two push pins 9 on the lower mounting frame 3 move downward, so that the upper mounting frame 2 moves upward and the lower mounting frame 3 moves downward, thereby increasing the angle between the upper and lower warps 4, making the two warps 4 away from the weft 13, and increasing the distance that the weft 13 can sag, which is conducive to avoiding the problem that the weft 13 is easily entangled with the warp 4 on the path due to the large width of the cloth;

[0126] After the adjustment is completed, the driving disk 8 is rotated by the first motor on the outer side of the machine base 1. During the rotation of the driving disk 8, the pushing pin 9 slides along the inside of the pushing frame 7, and the pushing frame 7 moves up and down, so that the upper mounting frame 2 and the lower mounting frame 3 move up and down, and because the limit shell 6 has been adjusted to move away from each other, the upper mounting frame 2 can move upward to a farther distance, and the lower mounting frame 3 can move downward to a farther distance, thereby increasing the angle between the upper and lower warps 4, so that the two warps 4 are away from the weft 13, and the distance that the weft 13 can sag is increased, which is conducive to the smooth passage of the weft 13 through the warp 4, and reduces the problem of the weft 13 and the warp 4 on the path.

[0127] When the upper mounting frame 2 and the lower mounting frame 3 are respectively limited by the limiting shell 6 and cannot slide, the push pin 9 will slide along the straight groove 801, and then compress the first spring 10, so that the compression elastic force of the first spring 10 increases;

[0128] In addition, during the up and down sliding of the upper mounting frame 2 and the lower mounting frame 3, the upper lead rod 201 and the lower lead rod 301 drive several warp threads 4 to perform an up and down staggered movement, so that the weft threads 13 sprayed by the water nozzle 12 can be clamped by the two warp threads 4, which is beneficial to improve the stability of the connection between the warp threads 4 and the weft threads 13, avoid the weft threads 13 from falling off, and improve the quality of the fabric.
