Description
Technical Field
The invention relates to a textile machine, in particular to a velvet weaving machine with a large flexible rapier.
Background
The existing velvet weaving machine is in a two-stage differentiation state, the double-layer double-shed double-sword-rod velvet weaving machine is advanced, can be produced by Van der Waals in Belgium and is very expensive, the double-layer double-shed double-sword-rod velvet weaving machine is only suitable for weaving middle-pound and heavy-pound velvet, the occupied area is large, the velvet weaving machine is also researched and developed by several factories in China, and huge investment is made in decades of times but the velvet weaving machine cannot be normalized. The single-layer single-shed shuttled velour loom is still vigorous at present, has low price, can weave thin velour which is difficult to weave by double rapier, and has small occupied area. They have in common the feature of having the necessary pile feeding means for weaving the velvet and of a clear and unobstructed passage for the shed. The difference is that the double-rapier loom weaves velour at the same time by weaving the upper layer and the lower layer, and can weave and cut the velour at the same time, find the defects in time, and the velour blank is layered and reeled, the velour surface is flat, and the style is superior. While the single-layer single-shed shuttled velvet weaving machine can only weave the upper layer and the lower layer in turn when weaving velvet, the efficiency is low, one weft winding process is needed, most velvet is cut under the machine, defects are found later, the repair is delayed, the velvet blank is wound in a double layer mode, and the velvet surface and the style are not in the same grade as the velvet surface and the style woven by the double rapier. Therefore, under the conditions of increasing renovation of velvet varieties, more and more fierce market competition and very tight labor force, a small rapier loom in the market is changed into a shuttle loom by some people to solve the problems that a guide rail of the small rapier is removed to enable a shed channel to be fresh and cool, a weft winding process is still required, an off-machine velvet cutting process is still required, the yield and the quality are still not obvious, and only thin velvet can be woven. Only this can be counterbalanced by a double-layer double-shed double-rapier velvet loom. Therefore, people hope to find a middle-grade velvet loom which has low price, high quality upper layer and can weave thin velvet which cannot be woven by a double-layer double-shed double-rapier loom in a double-layer double-shed double-rapier high-grade velvet loom and a single-layer single-shed general velvet loom with shuttles, so as to meet the requirements of increasing labor intensity and market competition.
Disclosure of Invention
The invention aims to provide a velvet loom with a large flexible rapier, which solves the key problem that a double-layer double-shed double-rapier velvet loom cannot weave thin velvet due to the fact that the velvet loom is a single-layer single-shed flexible large rapier velvet loom, can break through the problem that a double-layer double-shed double-rapier velvet pile face is single in cut velvet, also solves the problems that a single-layer single-shed velvet loom with a shuttle velvet has low yield and poor quality and has more weft winding processes, is low in price, makes up the blank of a middle-grade velvet loom, and is popular in the market.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a velvet loom with a large flexible rapier comprises a rear frame of a loom beam, a front frame of a loom grey cloth winding and a main frame of the loom weaving. And a velvet warp beam with the diameter of 80cm, a velvet warp beam with the diameter of 100cm, a ground warp feeding device and a velvet warp feeding device are arranged on a rear rack of the loom beam of the loom. The front frame for winding the grey cloth of the weaving machine is provided with a winding device with the diameter of the upper layer of the velvet blank being 70cm and a winding device with the diameter of the lower layer of the velvet blank being 70cm after velvet cutting. The main frame for weaving the loom is provided with a lifting shedding device for a velour ground warp and a velour warp, a picking and beating-up device for a velour ground weft and a velour cutting device for velour.
As an improvement of the invention, the pile warp shedding device is changed into a uniformly accelerated lifting shedding device instead of a conventional constant-speed lifting shedding device like a double-layer double-shed double-rapier loom and a single-layer single-shed shuttled pile loom in the lifting shedding motion from top to bottom or from bottom to top, and the uniformly accelerated lifting shedding device is designed according to the special curve principle of an eccentric cam, so that the pile warp can be wrapped on the ground weft and is more firmly fixed by the uniformly accelerated violence.
As an improvement of the invention, in the picking and beating-up device, the flexible rapier band reciprocates to connect and send the rapier head to complete picking movement. The cross section of the part of the flexible rapier belt entering the shed is in a slightly convex arc shape, so that the contact surface of the rapier belt and the lower layer warp yarns is reduced to generate extremely small friction, the warp yarns are prevented from generating broken yarns, and weaving is facilitated.
As a further improvement of the invention, the reciprocating motion of the flexible rapier tape is completed by a chain wheel of a rapier transmission gear box of the rapier loom driving a chain hole in the rapier tape. The invention increases the chain wheel by 0.07 percent, so that the time of the rapier belt in the weaving opening is shorter, the rapier belt can fast advance and fast exit, and the rapier belt can be woven more safely.
As a further improvement of the invention, the velvet cutting device is arranged between a reed fell and a front swing table of a main frame of the loom and consists of a servo motor, a universal joint, a speed change gear box, a linear guide rail, a synchronous belt, a knife grinding wheel, a velvet cutting knife rest and a velvet cutting blade, furthermore, a device capable of adjusting the front-back swing and left-right lifting is arranged on a base at two ends of the linear guide rail, so that the velvet cutting blade arranged on the linear guide rail can swing front-back or left-right lifting along with the front-back swing or left-right lifting. Compared with the prior art, the double-layer double-shed double-rapier velvet loom with the upper cut velvet can only cut one smooth velvet surface. Compared with a single-layer single-shed shuttleless velvet weaving machine, the lower machine velvet cutting device for cutting velvet on the inorganic upper part of the single-layer single-shed shuttleless velvet weaving machine can only cut one flat velvet surface, and the device can not only cut the flat velvet surface, but also cut the velvet surface which is wavy in the warp direction and the weft direction and even has an inclined pile cross section.
Compared with a double-layer double-shuttle double-rapier velvet loom, the velvet loom with the large flexible rapier has the advantages that the positions of the left and right rigid rapier for stretching in and out are saved, the occupied area is greatly reduced, and the rapier head butt joint is easy to control.
Compared with the prior art, the invention has the following advantages and effects:
compared with a double-layer double-shuttle double-rapier velvet loom, the double-side rigid rapier loom omits the position of extending in and out, and the occupied area is greatly reduced. And the butt joint of the rapier head is easy to debug and control, the cut pile surface not only can be smooth, but also has more warp-wise wave shape, weft-wise wave shape, even the inclined section shape of the pile head and the like. The method can be mainly used for manufacturing thin and ultra-thin velvet, the yield is only three-fourth of that of a double-layer double-shuttle double-rapier velvet loom, the price is only one tenth of that of the double-layer double-shuttle double-rapier velvet loom, and the cost performance is high. Compared with a single-layer single-shuttle shuttled velvet weaving machine, the on-machine velvet cutting device is additionally arranged, the weft winding process is also omitted, the stand rate of workers is increased, the product style and the product quality are greatly improved, although the price is improved by three times than that of the single-layer single-shuttle shuttled velvet weaving machine, the yield is more than two times that of the single-layer single-shuttle shuttled velvet weaving machine. The performance-price ratio is still higher by analyzing the stand rate of workers and the style of products. It is also worth mentioning that as the lifting heald is changed into the uniform acceleration, the uniform acceleration of the fulminant force can enable the pile warp to be consolidated more firmly, and as the rapier tape is changed into the fast-in and fast-out mode when entering and exiting the shed, and the section of the rapier tape is changed into the slightly-convex arc shape, the failure rate of warp and weft yarns of the warp surface is greatly reduced.
In general, the velvet loom with the large flexible rapier solves the key problem that a double-layer double-shed double-rapier velvet loom cannot weave thin velvet, solves the problem that a double-layer double-shed double-rapier velvet pile face is single, solves the problems that a single-layer single-shed velvet loom with a shuttle velvet has low yield and poor quality and has one more weft winding process, is low in price, makes up the blank of a middle-grade velvet loom, and is popular in the market.

Detailed Description
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1 and fig. 2 to 5, the velvet weaving machine of the flexible large rapier comprises a front frame 01, a middle frame 02, a rear frame 03 and a step board 04, wherein the front frame 01 is provided with an upper layer blank roll 11 and an upper layer blank roll coiling device 23, and is further provided with a lower layer blank roll 12 and a lower layer blank roll coiling device 24. The rear frame 03 is provided with a ground warp beam 13 and a ground warp beam let-off device 21, and is further provided with a pile warp beam 14 and a pile warp beam let-off device 22. On the middle frame 02, a ground warp lifting heald device 31, a pile warp lifting heald device 32, a weft feeding device and a weft receiving device 41, a beating-up device 51 and a pile cutting device 61 are arranged.
In the figure, 71 represents a ground warp yarn, and 72 represents a pile warp yarn. Some known accessories of the weaving machine are all included in the large movements of warp let-off, heald lifting, picking, beating-up and winding of the weaving machine, and are not described in more detail. However, the velvet weaving machine with the flexible large rapier has the following main technical characteristics.
The schematic diagram of the lifting track of the pile warp heald frame 321 shown in fig. 2 is that the heald frame 321 is rocked up and down by a rocker 325, the heald frame is lifted up and down by a traction rope 322 connecting the heald frame and the lifting rocker via a pulley 323 above the heald frame and a steering eccentric pulley 324, and the heald frame is lifted up and down by a heald frame reset tension spring 326, and the core is that the steering eccentric pulley 324 can make the heald frame generate uniform acceleration motion when the heald frame is lifted up and down, and the uniform acceleration violent force can make the pile warp generate larger cohesive force when being wrapped on the ground weft, so that the pile warp is fixed more firmly. It has been further shown that the rocker 325 is moved downwards at a constant speed by means of the pulling cable 322 to lift the pile warp shafts 321 upwards, while the deflection takes place by means of the deflection eccentric 324, whereby an acceleration takes place from a minimum to a maximum distance from the centre of the circle due to the eccentricity of the deflection eccentric 324. Similarly, when the rocker 325 pulls down the heddle shaft 321 via the pulling rope 322 and the restoring spring 326 at a constant speed upwards, and is now turned by the turning eccentric 324, an acceleration is also produced from the maximum to the minimum from the centre of the circle due to the eccentricity of the turning eccentric 324. The mechanical principle that the two-way acceleration can be realized and the upper part and the lower part of the heald frame can be utilized is characterized in that the upper part and the lower part of the heald frame are uniformly accelerated to generate violence, so that the pile warp can be wrapped on the ground weft to be firmly fixed.
In the schematic cross-sectional view of the rapier tape 411 shown in fig. 3, one end of the rapier tape 411 is provided with a weft receiving rapier head and a weft feeding rapier head 412, the rapier tape 411 can be divided into a part Y with a sprocket transmission hole and an opening part X capable of extending into and retracting out warp yarns to be lifted, the core is that the Y part in the rapier tape 411 is provided with a sprocket transmission hole 413, and the cross-section 414 of the X part is in an arc shape with a slight bulge, so that the friction with the warp yarns can be reduced to the greatest extent during the extending and retracting movement of the opening part of the warp yarns, the fuzzing is avoided, and the weaving is very facilitated.
In the schematic view of the rapier driving sprocket 41 shown in FIG. 4, the fast and slow time of the rapier belt 411 entering and exiting the shedding portion is determined by the rapier conveying device in the weft feeder 41. In order to enable the rapier tape 411 to fast advance and fast exit in the opening movement, the rapier transmission chain wheel 415 is changed into the rapier transmission chain wheel 416 by increasing 0.07 percent of the diameter under the condition that the horizontal position and the high-low vertical position of the rapier transmission chain wheel 411 are not changed. In the simplest way, a rapier transmission box of a 200cm specification rapier loom is arranged on a 150cm specification rapier loom, a rapier transmission box of a 250cm specification rapier loom is arranged on a 200cm specification rapier loom, and so on. Thereby leading the rapier tape 411 to fast go out in the warp yarn opening, avoiding the warp yarn from being fluffed and dislocated due to friction of the rapier tape, and being more beneficial to weaving.
The velvet pile cutting device 61 shown in fig. 5 is composed of a servo motor 611, a servo motor output shaft 612, an output shaft universal joint 613 mounted at one end of the servo motor output shaft 612, a speed change gear box 614 connected with the output shaft universal joint 613, and a linear guide rail 615 controlled by the speed change gear box. The linear guide 615 has a left pulley 616 on the left side and a right pulley 617 on the right side, and a synchronous belt 618 powered by a change gear box 614 is sleeved on the pulleys, and the synchronous belt 618 pulls a cutting blade carrier and a cutting blade 619 mounted on the linear guide 615. The velvet cutting knife rest and the velvet cutting blade 619 move back and forth through the power conversion of the servo motor 611 to cut off the velvet connected with the upper layer and the lower layer to form an upper layer velvet blank and a lower layer velvet blank. The core of the invention is that the cutting device is also provided with a linear guide rail left seat 6111, a linear guide rail right seat 6112 and a connecting shaft 6113 of the linear guide rail left seat and the linear guide rail right seat. The left seat 6111 and the right seat 6112 of the linear guide rail are respectively provided with an eccentric cam, so that the linear guide rail 615 can swing back and forth and lift left and right through the connecting shaft 6113. Although this is only a difference of 1-2 mm, it is already evident for velour surfaces. Therefore, the velvet weaving machine with the large flexible rapier can cut velvet, can cut flat velvet, warp-wise wavy and weft-wise wavy and even has inclined pile, and is popular with customers.
In conclusion, the velvet loom with the large flexible rapier has the advantages that the double-layer double-shed double-rapier velvet loom is provided with the flexible rapier, so that the double-layer double-shed double-rapier velvet loom has smaller occupied area compared with a rigid rapier, can weave thin velvet, and can weave flat warp-wise waves, weft-wise waves and inclined pile end faces. This is not possible in any way with double-layer double-shed double rapier looms. The velvet loom with the large flexible rapier reduces one weft winding process and increases a plurality of stand rates for a single-layer single-shed velvet loom with the shuttled velvet, velvet can be cut on the loom, defects can be found timely, and the style and quality of the velvet surface are increased by one step.
Furthermore, the velvet warp opening device is provided with an accelerating device, so that the velvet warp is more firmly solidified. According to the velvet loom with the large flexible rapier, the section of the inlet and outlet opening part of the rapier tape is in a slightly convex arc shape, so that the warp surface friction can be reduced, and the velvet loom is different from other rapier tapes. According to the velvet weaving machine with the large flexible rapier, the configuration of the rapier transmission chain wheel is enlarged by one stage, so that the rapier tape can rapidly advance and rapidly exit in the warp yarn opening, the weaving warp surface is smoother, and the occurrence of broken filaments is avoided. The flexible rapier velvet weaving machine is also provided with a velvet cutting device, and can cut flat, wavy and inclined piles. Most importantly, the flexible rapier velour loom provided by the invention has the advantages that although the yield is only two thirds of that of a double-layer double-shed double rapier, the price is only one tenth of that of the double-layer double-shed double rapier, and a plurality of pile face shapes can be woven. Similarly, although the price of the flexible rapier velvet loom is three times that of a single-layer single-shuttle velour loom, one weft winding process is omitted, one velvet cutting device is added, and the style and the quality of the velvet surface are stepped.
Therefore, the velvet loom with the large flexible rapier overcomes the defects of the high-end velvet looms and the large-path velvet looms in the prior velvet looms, makes up the blank of the middle-grade velvet looms, and has a huge market.
