Description

Technical Field

[0001] The invention relates to the field of seamless wall cloth processing equipment, in particular to a base cloth weft straightening processing system for seamless wall cloth. Background Art

[0002] In specific usage feedback, seamless wall cloth has shown advantages such as distinct texture, soft texture, sound absorption and breathability, not easy to crack, simple mounting, easy replacement, and can be cleaned with water. Hot melt adhesive seamless wall cloth is one of the mainstream products. The hot melt adhesive on the back of the seamless wall cloth is made by melting EVA adhesive powder at high temperature and then scraping it on the base cloth. The adhesive film and the back of the wall cloth are then hot-ironized and melted before being compounded together. Before this operation, the base cloth needs to be straightened.

[0003] Weft straightening is to adjust the base fabric that is in weft obliqueness (the fabric is in a continuous traction state and is affected by various mechanical movements and production operations, which often causes the weft yarn to be skewed or bent). If the weft obliqueness is not adjusted properly, it will easily cause uneven hot melt adhesive, which will affect the overall quality of the hot melt adhesive seamless wall covering.

[0004] At the same time, most of the existing weft straightening technologies only have a weft straightening mechanism, and no base fabric holding mechanism is added. When faced with fabric that is continuously in a traction state, even after adjustment, it will continue to be affected by various mechanical movements and production operations, thereby causing the problem of uneven hot melt adhesive. Summary of the Invention

[0005] (1) Technical problems solved

[0006] The purpose of the embodiment of the present invention is to provide a base fabric weft straightening processing system for seamless wall cloth, aiming to solve the problem that in the existing weft straightening technology, most of them only have a weft straightening mechanism, and no base fabric holding mechanism is added. When faced with fabric that is continuously in a traction state, even after adjustment, it will continue to be affected by various mechanical movements and production operations, thereby causing uneven hot melt adhesive.

[0007] (2) Technical solution

[0008] The base fabric weft straightening processing system of seamless wall cloth includes a weft straightening machine box, inside which a weft straightening roller group for straightening the base fabric is installed; the weft straightening roller group includes a tension weft straightening roller group, and the tension weft straightening roller group is composed of multiple tension weft straightening rollers controlled by cylinder lifting, and the multiple tension weft straightening rollers are first-level tension weft straightening rollers, second-level tension weft straightening rollers and third-level tension weft straightening rollers with the same structure; the first-level tension weft straightening roller includes a base fabric limiting mechanism and a transmission roller; the transmission roller is used to pull the transmission base fabric forward during rotation, and cooperates with the cylinder for lifting and lowering adjustment to form a different degree of staggered distribution with the second-level tension weft straightening roller and the third-level tension weft straightening roller, thereby completing the tension adjustment of the base fabric during the weft straightening process; two base fabric limiting mechanisms are provided and distributed at both ends of the transmission roller; the base fabric limiting mechanism is used to limit the base fabric from both sides during the process of the transmission roller pulling the transmission base fabric forward.

[0009] After the cylinder controls the transmission roller to rise and fall, it controls the height adjustment of multiple tightness weft straightening rollers, that is, the different degrees of staggered distribution of the first-level tightness weft straightening roller, the second-level tightness weft straightening roller and the third-level tightness weft straightening roller, and cooperates with the transmission roller to pull the transmission base cloth forward to complete the tightness adjustment of the weft straightening process of the base cloth, so as to cope with the elastic changes of the base cloth's own material when it is continuously in the traction state, and avoid the situation where secondary weft skew occurs when continuing to pull after weft straightening; in the process of the transmission roller rotating and pulling the transmission base cloth forward, the base cloth limiting mechanism is used to limit the base cloth from both sides to achieve stable forward transmission of the base cloth, and avoid the problem of uneven hot melt adhesive caused by the cloth being continuously in the traction state even after adjustment.

[0010] The technical solution of this application is further described below:

[0011] In one embodiment, the base fabric limiting mechanism includes a limiting head and a transmission head; the transmission head is rotatably connected to the weft straightening machine chassis and receives the rotational power provided by the weft straightening machine chassis; the limiting head is installed on the transmission head by means of an additional ring and bolts, and is used to receive the rotational power provided by the transmission head and rotate synchronously with the transmission roller; wherein the limiting head is composed of a limiting plate and a plurality of unit limiting heads installed in a ring array on the limiting plate.

[0012] In a further embodiment, the unit limit head includes multiple automatic telescopic rods A, and the multiple automatic telescopic rods A are detachably connected end to end in a straight line using a connecting plate structure; an additional plate is provided at one end of the end-to-end connection body of the multiple automatic telescopic rods A, and a support platform is provided at the other end; the additional plate is installed on the limit plate.

[0013] Optimized, the connecting plate structure is provided with two connecting plates, which are connected by multiple screws; an automatic telescopic rod B is installed through the support platform, and a pressing head is installed at the end of the automatic telescopic rod B away from the support platform. An elastic pressing plate is provided on the pressing head, and the elastic pressing plate is elastically connected to the pressing head through multiple springs.

[0014] At the same time, the lengths of the multiple automatic telescopic rods A can be adjusted to accommodate base fabrics of different sizes, thereby achieving stable forward transmission of the base fabric.

[0015] In a further embodiment, the transmission head includes a driven rotating shaft, which is installed on a limit plate through an additional ring, and the limit plate is fixed on the transmission roller; a bearing ring is fixed on the driven rotating shaft, and is rotatably connected to the weft straightening machine case by using the bearing ring, and an active rotating shaft is fixed on the driven rotating shaft, and the active rotating shaft is connected to the rotational power provided by the weft straightening machine case.

[0016] In one embodiment, the weft straightening roller group further includes a symmetrical outer weft straightening roller group, which is used for transverse weft straightening of the base fabric; the symmetrical outer weft straightening roller group is composed of a symmetrical outer weft straightening roller and a plurality of auxiliary pressing rollers distributed in a circular array around the symmetrical outer weft straightening roller; the plurality of auxiliary pressing rollers are rotatably connected to the inside of the weft straightening machine chassis, and form a system that squeezes the base fabric from all sides of the symmetrical outer weft straightening roller and fits it onto the symmetrical outer weft straightening roller, so that the symmetrical outer weft straightening roller can transmit the base fabric forward longitudinally while stabilizing the transverse weft straightening base fabric.

[0017] In a further embodiment, the symmetrical external weft straightening roller is composed of a support roller and a plurality of unit external weft straightening structures arranged on the support roller; the support roller is driven by a rotational power provided by a weft straightening chassis through an external rack ring at the end; the support roller synchronously drives the plurality of unit external weft straightening structures to rotate longitudinally forward to transmit the base cloth longitudinally while utilizing the plurality of unit external weft straightening structures themselves for transverse transmission to complete the stabilization of the transverse weft straightening base cloth.

[0018] Optimized, the unit external pulling and weft straightening structure includes a turntable, an annular groove body is opened on the turntable, and a transverse external pulling piece is installed inside the annular groove body; an inner rotating shaft is movably inserted into the end heads at both ends of the support roller, and the inner rotating shaft is rotatably connected to the support roller through a bearing, and the end head of the inner rotating shaft is fixed inside the weft straightening machine chassis; the inner rotating shaft uses the transverse rotating drive member provided thereon to trigger the transverse external pulling piece to rotate transversely to perform transverse weft straightening of the base cloth; a plurality of transverse rotating drive members are provided, and they are in a one-to-one correspondence with the plurality of unit external pulling and weft straightening structures.

[0019] Therefore, the rotational power provided by the weft straightening machine chassis drives the rack ring and the supporting roller to rotate, forming a relative rotation with the inner rotating shaft. The inner rotating shafts at the ends of the two ends of the supporting roller form a symmetrical bilateral structure, which triggers the transverse rotating driving member to drive the transverse outer pulling member to rotate transversely to perform transverse weft straightening of the base cloth, so that the supporting roller can synchronously drive the multiple unit outer pulling weft straightening structures to rotate and transmit the base cloth longitudinally forward, and at the same time utilize the multiple unit outer pulling weft straightening structures themselves to transmit transversely to complete stable transverse weft straightening of the base cloth; because the multiple unit outer pulling weft straightening structures perform weft straightening through their own transverse transmission on the basis of the overall longitudinal transmission, a full-range high-coverage transverse weft straightening base cloth is achieved on the basis of stable longitudinal forward transmission of the base cloth, thereby improving the stable weft straightening effect;

[0020] At the same time, it cooperates with the longitudinal weft straightening base fabrics with different degrees of staggered distribution of the first-level elasticity weft straightening roller, the second-level elasticity weft straightening roller and the third-level elasticity weft straightening roller to cope with wrinkles in different directions in multiple parts of the base fabric.

[0021] The transverse rotation driving member includes an active external threaded tube, which is fixed on the inner rotating shaft; the outside of the active external threaded tube is engaged with a plurality of transition gears distributed in a ring array around the active external threaded tube, the transition gears rotate inside the annular groove body, and the transition gears are engaged with a driven gear on the side away from the active external threaded tube; there are multiple driven gears, which are distributed in a ring array around the active external threaded tube; the driven gears are arranged on the transverse external pulling member; the teeth of the driven gears and the transition gears are arranged inclined, so as to convert the longitudinal rotation power provided by the active external threaded tube into transverse rotation power.

[0022] The transverse external pulling member is composed of a plurality of turntables distributed in a circular array around the active external threaded tube; the turntables are laid flat in the radial direction of the active external threaded tube, and the plurality of turntables and the plurality of driven gears are arranged in a cross-circular array around the active external threaded tube, and the turntables and the driven gears are rotatably connected through a universal joint; the outer edge of the turntable is arranged in an arc shape.

[0023] After the supporting roller rotates relative to the inner rotating shaft, the active external threaded tube rotates relative to the transition gear. Since the gear teeth of the driven gear and the transition gear are tilted, the longitudinal rotational power provided by the active external threaded tube is converted into transverse rotational power, thereby driving the multiple turntables on the transverse external pulling member to transmit transversely for weft straightening; since the multiple unit external pulling weft straightening structures transmit transversely for weft straightening on the basis of the overall longitudinal transmission, the stable longitudinal forward transmission of the base cloth is achieved on the basis of all-round high coverage transverse weft straightening of the base cloth, thereby improving the stable weft straightening effect; since the outer edge of the turntable is arranged in an arc shape, the loss of base is avoided.

[0024] (3) Beneficial effects

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1) After the cylinder controls the transmission roller to lift and lower, it controls the height adjustment of multiple tension weft straightening rollers, i.e., the different degrees of dislocation distribution of the first-level tension weft straightening roller, the second-level tension weft straightening roller, and the third-level tension weft straightening roller. The transmission roller pulls the transmission base fabric forward to complete the tension adjustment of the base fabric during the weft straightening process, so as to cope with the elastic changes of the base fabric itself in the continuous traction state, and avoid the secondary weft skew caused by continued traction after weft straightening. In the process of the transmission roller rotating and pulling the transmission base fabric forward, the base fabric limiting mechanism is used to limit the base fabric from both sides to achieve stable forward transmission of the base fabric, so as to avoid the problem of uneven hot melt adhesive caused by the fabric being continuously in the traction state, even after adjustment.

[0027] 2) Multiple automatic telescopic rods A can be adjusted in length to accommodate base fabrics of different sizes, thus achieving stable forward transmission of the base fabric;

[0028] 3) The rotational power provided by the weft straightening chassis drives the rack ring and the support roller to rotate, forming a relative rotation with the inner rotating shaft. The inner rotating shafts at the ends of the support rollers form a symmetrical bilateral structure, which triggers the transverse rotating drive to drive the transverse outer pulling member to rotate transversely to perform transverse weft straightening of the base fabric, so that the support rollers can synchronously drive multiple units of the outer pulling weft straightening structure to rotate and transmit the base fabric forward longitudinally. At the same time, the multiple units of the outer pulling weft straightening structure themselves are used for transverse transmission to complete the stable transverse weft straightening of the base fabric; because the multiple units of the outer pulling weft straightening structure perform transverse transmission on the basis of the overall longitudinal transmission to straighten the weft, a full range of high coverage transverse weft straightening base fabric is achieved on the basis of stable longitudinal forward transmission of the base fabric, thereby improving the stable weft straightening effect; at the same time, the longitudinal weft straightening base fabric with different degrees of staggered distribution of the first-level elasticity weft straightening roller, the second-level elasticity weft straightening roller and the third-level elasticity weft straightening roller cooperate to achieve the purpose of coping with wrinkles in different directions in multiple parts of the base fabric;

[0029] 4) After the supporting roller rotates relative to the inner rotating shaft, the active external threaded tube rotates relative to the transition gear. Since the gear teeth of the driven gear and the transition gear are tilted, the longitudinal rotational power provided by the active external threaded tube is converted into transverse rotational power, thereby driving the multiple turntables on the transverse external pulling member to perform transverse transmission for weft straightening. Since the multiple unit external pulling weft straightening structures perform transverse transmission on the basis of the overall longitudinal transmission for weft straightening, the stable longitudinal forward transmission of the base fabric and the all-round high coverage transverse weft straightening base fabric are achieved, thereby improving the stable weft straightening effect. Since the outer edge of the turntable is arranged in an arc shape, the loss of base is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0057] In the embodiment of the present invention, please refer to Figure 2 : A base fabric weft straightening processing system for seamless wall cloth, comprising a weft straightening chassis 1, inside which a weft straightening roller group 6 for straightening the base fabric is installed;

[0058] It should be noted that: Figure 1 and Figure 2A weft straightening machine chamber 5 is provided inside the weft straightening machine case 1, and a weft straightening roller group 6 is installed inside the weft straightening machine chamber 5; a feed slot is provided on the top of the weft straightening machine case 1, and the feed slot is used to introduce the base fabric into the weft straightening machine chamber 5 connected thereto; a base fabric feeder cover 2 is hingedly installed on the weft straightening machine case 1 outside the feed slot; a plurality of support legs 3 are installed at the bottom of the weft straightening machine case 1, and the support legs 3 are used for stable support; an operation panel 4 is installed on the front surface of the weft straightening machine case 1, and a display screen for observation is installed on the operation panel 4, and the display screen is connected to a plurality of cameras installed inside the weft straightening machine chamber 5;

[0059] Meanwhile, except for the above-mentioned weft straightening machine, the components not described are prior art, and their detailed structures can be found in existing literature and journals, and they can also be purchased directly on the market, or can be assembled by purchasing components on the market, etc.; they are not what the present invention is intended to protect, and are not described in detail here, nor are they drawn in the drawings;

[0060] Continue reading Figure 10 The weft straightening roller group 6 includes a tension weft straightening roller group, which is composed of a plurality of tension weft straightening rollers controlled by cylinders. The plurality of tension weft straightening rollers are a first-level tension weft straightening roller 800, a second-level tension weft straightening roller 900, and a third-level tension weft straightening roller 1000 with the same structure.

[0061] Therefore, a cylinder is used to control the height adjustment of multiple tension straightening rollers, that is, the first tension straightening roller 800, the second tension straightening roller 900 and the third tension straightening roller 1000 are staggered to different degrees to complete the tension adjustment of the base fabric during the weft straightening process, so as to cope with the elastic changes of the base fabric itself when it is continuously in the traction state, and avoid the situation where the secondary weft skew occurs when the traction is continued after the weft straightening (this process can be specifically referred to Figure 11 Demonstration diagram of the elasticity weft straightening roller group straightening the base fabric);

[0062] At the same time, it should be noted that, in addition to the first-level tension straightening roller 800, the second-level tension straightening roller 900 and the third-level tension straightening roller 1000, the multiple tension straightening rollers may also include fourth-level tension straightening rollers, fifth-level tension straightening rollers, etc. There is no limit to the specific number of tension straightening rollers, as long as they can meet the tension adjustment of the weft straightening process for different degrees of dislocation distribution to cope with the elastic changes of the base fabric itself when it is continuously in a traction state. Here, the first-level tension straightening roller 800, the second-level tension straightening roller 900 and the third-level tension straightening roller 1000 are preferably used;

[0063] Continue reading Figure 12 : The first-level elasticity weft straightening roller 800 includes a base cloth limiting mechanism 810 and a transmission roller 820;

[0064] The driving roller 820 is used to pull the base fabric forward during the rotation process, and cooperates with the cylinder to adjust the lifting and lowering, forming different degrees of offset distribution with the secondary tension straightening roller 900 and the tertiary tension straightening roller 1000, completing the tension adjustment of the base fabric during the weft straightening process;

[0065] Two base fabric limiting mechanisms 810 are provided and are distributed at both ends of the transmission roller 820; the base fabric limiting mechanisms 810 are used to limit the base fabric from both sides during the process of the transmission roller 820 pulling the base fabric forward;

[0066] Therefore, in the process of the transmission roller 820 rotating and pulling the base cloth forward, the base cloth limiting mechanism 810 is simultaneously used to limit the base cloth from both sides to achieve stable forward transmission of the base cloth, avoiding the problem of uneven hot melt adhesive caused by the cloth being continuously in a pulling state and being affected by various mechanical movements and production operations even after adjustment.

[0067] In general, after the cylinder controls the transmission roller 820 to be raised and lowered, the height adjustment of multiple tension straightening rollers is controlled, that is, the first-level tension straightening roller 800, the second-level tension straightening roller 900 and the third-level tension straightening roller 1000 are staggered to different degrees, and the transmission roller 820 is used to pull the transmission base cloth forward to complete the tension adjustment of the base cloth during the weft straightening process, so as to cope with the elastic changes of the base cloth's own material when it is continuously in the traction state, and avoid the situation where secondary weft skew occurs when continuing to pull after weft straightening; in the process of the transmission roller 820 rotating and pulling the transmission base cloth forward, the base cloth limiting mechanism 810 is used to limit the base cloth from both sides to achieve stable forward transmission of the base cloth, so as to avoid the problem of uneven hot melt adhesive due to the cloth being continuously in the traction state, even after adjustment.

[0068] In the embodiment of the present invention, please refer to Figure 12-14 : The base fabric limiting mechanism 810 includes a limiting head 830 and a transmission head 840;

[0069] The transmission head 840 is rotatably connected to the weft straightening machine chassis 1 and receives the rotational power provided by the weft straightening machine chassis 1;

[0070] The limit head 830 is installed on the transmission head 840 by adding a ring 833 and bolts, and is used to receive the rotational power provided by the transmission head 840 and rotate synchronously with the transmission roller 820; wherein, the limit head 830 is composed of a limit plate 831 and a plurality of unit limit heads 832 installed in a ring array on the limit plate 831.

[0071] Therefore, the transmission head 840 synchronously drives the limit head 830 and the transmission roller 820 to rotate, so that the limit head 830 uses multiple unit limit heads 832 distributed in a circular array to cooperate with the transmission roller 820 in sequence to rotate and pull the transmission base cloth forward to limit the base cloth, thereby realizing stable forward transmission of the base cloth, avoiding the problem of uneven hot melt adhesive caused by the cloth being continuously in a traction state, even after adjustment, it will continue to be affected by various mechanical movements and production operations.

[0072] In the embodiment of the present invention, please refer to Figure 14 and Figure 16 : The unit limit head 832 includes multiple automatic telescopic rods A8322, and the multiple automatic telescopic rods A8322 are detachably connected end to end in a straight line using a connecting plate structure 8323; an additional plate 8321 is provided at one end of the end-to-end connection body of the multiple automatic telescopic rods A8322, and a support platform 8325 is provided at the other end; the additional plate 8321 is installed on the limit plate 831.

[0073] Optimized, the connecting plate structure 8323 is provided with two connecting plates, which are connected by multiple screws; an automatic telescopic rod B8324 is installed through the support platform 8325, and a pressing head 8326 is installed at the end of the automatic telescopic rod B8324 away from the support platform 8325. The pressing head 8326 is provided with an elastic pressing plate 8327, and the elastic pressing plate 8327 is elastically connected to the pressing head 8326 through multiple springs.

[0074] Therefore, the transmission head 840 synchronously drives the limit head 830 and the transmission roller 820 to rotate, and the multiple unit limit heads 832 distributed in a ring array cooperate with the transmission roller 820 to rotate and pull the transmission base cloth forward in turn. When the unit limit head 832 rotates to the position where the base cloth and the transmission roller 820 are in contact, the multiple automatic telescopic rods A8322 provided therewith are extended to push the support platform 8325 and the pressing head 8326 to the outside of the base cloth, and then the automatic telescopic rod B8324 is started to drive the pressing head 8326 and the elastic pressing plate 8327 to elastically press on the base cloth to limit the base cloth; when the transmission roller 820 continues to rotate, the automatic telescopic rod A8322 is started to The movable telescopic rod B 8324 drives the pressing head 8326 and the elastic pressing plate 8327 to leave the base fabric, and the automatic telescopic rod A 8322 shortens and retracts the support platform 8325 and the pressing head 8326. Then, the next unit limiting head 832 continues the above operation. The limiting head 830 utilizes a plurality of unit limiting heads 832 distributed in a circular array to sequentially cooperate with the driving roller 820 to rotate and limit the base fabric during the forward traction process, thereby achieving stable forward transmission of the base fabric and avoiding the problem of uneven hot melt adhesive caused by the fabric being continuously in a traction state and being affected by various mechanical movements and production operations even after adjustment.

[0075] At the same time, multiple automatic telescopic rods A8322 can adjust their own lengths to adapt to base fabrics of different sizes and achieve stable forward transmission of the base fabric.

[0076] It should be noted that:

[0077] First, the automatic telescopic rod A8322 and the automatic telescopic rod B8324 can be cylinder telescopic rods, hydraulic telescopic rods, or electric telescopic rods, etc. There is no limitation on the specific structure, as long as it can meet the requirements of telescopic adjustment. Here, cylinder telescopic rods are preferably used.

[0078] Second, the specific number of the multiple automatic telescopic rods A8322 can be two, three, four... There is no limit to the specific number, as long as it can meet the requirements of being able to adjust its own length to adapt to base cloths of different sizes and achieve stable forward transmission of the base cloth. Two are preferably used here.

[0079] In the embodiment of the present invention, please refer to Figure 15 : The transmission head 840 includes a driven shaft 842, which is mounted on a limit plate 831 via a mounting ring 833, and the limit plate 831 is fixed on the transmission roller 820;

[0080] A bearing ring 843 is fixed on the driven shaft 842 and is rotatably connected to the weft straightening machine chassis 1 via the bearing ring 843 . A driving shaft 841 is fixed on the driven shaft 842 and receives the rotational power provided by the weft straightening machine chassis 1 .

[0081] In the embodiment of the present invention, please refer to Figure 3 and Figure 4 The weft straightening roller group 6 further includes a symmetrical outer weft straightening roller group 700, which is used to horizontally straighten the base fabric (the direction of the horizontal weft straightening base fabric is along the roller body direction of the weft straightening roller group 6 and is perpendicular to the longitudinal forward transmission direction of the primary tension weft straightening roller 800);

[0082] The symmetrical outer weft straightening roller group 700 is composed of a symmetrical outer weft straightening roller 720 and a plurality of auxiliary pressing rollers 710 distributed in a circular array around the symmetrical outer weft straightening roller 720; the plurality of auxiliary pressing rollers 710 are rotatably connected to the inside of the weft straightening machine box 1, and form a symmetrical outer weft straightening roller 720 to squeeze the base fabric onto the symmetrical outer weft straightening roller 720 (this process can be specifically referred to Figure 4 The symmetrical outer weft straightening roller group 720 is provided as a demonstration diagram of the weft straightening base fabric, so that the symmetrical outer weft straightening roller 720 can transmit the base fabric forward longitudinally while stabilizing the weft straightening base fabric in the transverse direction.

[0083] Therefore, the symmetrical outer weft straightening roller 720 is started, and the base cloth is transmitted longitudinally forward by the symmetrical outer weft straightening roller 720. At the same time, a plurality of auxiliary pressing rollers 710 connected to the inside of the weft straightening chassis 1 are rotated to squeeze the base cloth onto the symmetrical outer weft straightening roller 720 from all sides, so that the symmetrical outer weft straightening roller 720 can transmit the base cloth longitudinally forward while stabilizing the weft straightening base cloth transversely.

[0084] In the embodiment of the present invention, please refer to Figure 5 The symmetrical outer weft straightening roller 720 is composed of a support roller 730 and a plurality of unit outer weft straightening structures 740 arranged on the support roller 730;

[0085] The support roller 730 is driven by the rotational power provided by the weft straightening chassis 1 through the external rack ring at the end (the specific rack ring is arranged on the outside of the end of the support roller 730, and the device for providing the rotational power of the weft straightening chassis 1 is a motor, and the motor is transmitted to the rack ring through a gear set); the support roller 730 drives the multiple unit external pulling weft straightening structures 740 to rotate longitudinally and transmit the base cloth forward longitudinally, while using the multiple unit external pulling weft straightening structures 740 themselves for lateral transmission to complete the stabilization of the lateral weft straightening base cloth.

[0086] Therefore, the rotational power provided by the weft straightening chassis 1 drives the rack ring and the support roller 730 to rotate, so that the support roller 730 synchronously drives the multiple unit external pulling weft straightening structures 740 to rotate and transmit the base cloth longitudinally forward, while utilizing the multiple unit external pulling weft straightening structures 740 themselves for transverse transmission to complete stable transverse weft straightening of the base cloth; since the multiple unit external pulling weft straightening structures 740 perform weft straightening through their own transverse transmission on the basis of the overall longitudinal transmission, a full-range high-coverage transverse weft straightening base cloth is achieved on the basis of stable longitudinal forward transmission of the base cloth, thereby improving the stable weft straightening effect.

[0087] In the embodiment of the present invention, please refer to Figure 5-9 The unit outward pulling and weft straightening structure 740 includes a turntable 742, an annular groove is provided on the turntable 742, and a transverse outward pulling member 741 is installed inside the annular groove;

[0088] An inner rotating shaft 750 is movably inserted into the ends of both ends of the support roller 730. The inner rotating shaft 750 is rotatably connected to the support roller 730 through a bearing 760. The ends of the inner rotating shaft 750 are fixed inside the weft straightening machine box 1.

[0089] The inner rotating shaft 750 uses the lateral rotation driving member provided thereon to trigger the lateral outer pulling member 741 to lateral rotate to perform lateral weft straightening of the base cloth;

[0090] There are multiple transverse rotation driving members, which correspond one-to-one to the multiple unit outward pulling and weft straightening structures 740.

[0091] Therefore, the rotational power provided by the weft straightening chassis 1 drives the rack ring and the support roller 730 to rotate, forming a relative rotation with the inner rotating shaft 750. The inner rotating shaft 750 at the end of the support roller 730 forms a symmetrical two-sided structure, which triggers the horizontal rotation driving member to drive the horizontal outer pulling member 741 to rotate horizontally to perform horizontal weft straightening of the base cloth, so that the support roller 730 can synchronously drive the multiple unit outer pulling weft straightening structures 740 to rotate forward to transmit the base cloth longitudinally, and at the same time, the multiple unit outer pulling weft straightening structures 740 themselves can be used for horizontal transmission to complete stable horizontal weft straightening of the base cloth; since the multiple unit outer pulling weft straightening structures 740 perform weft straightening through their own horizontal transmission on the basis of the overall longitudinal transmission, a full-range high-coverage horizontal weft straightening base cloth is achieved on the basis of stable longitudinal forward transmission of the base cloth, thereby improving the stable weft straightening effect.

[0092] In the embodiment of the present invention, please refer to Figure 8 and Figure 9 The horizontal rotation drive member includes an active external threaded tube 7414, which is sleeved and fixed on the inner rotating shaft 750; the active external threaded tube 7414 is meshed with a plurality of transition gears 7413 distributed in an annular array around the active external threaded tube 7414 on the outside, the transition gear 7413 rotates inside the annular groove, and the transition gear 7413 is meshed with a driven gear 7412 on the side away from the active external threaded tube 7414; a plurality of driven gears 7412 are provided, and are distributed in an annular array around the active external threaded tube 7414;

[0093] The driven gear 7412 is arranged on the transverse outer pull piece 741; the gear teeth of the driven gear 7412 and the transition gear 7413 are arranged tilted, which is used to convert the longitudinal rotation power provided by the active external threaded tube 7414 into transverse rotation power.

[0094] Therefore, the rotational power provided by the weft straightening machine chassis 1 drives the rack ring and the support roller 730 to rotate, forming a relative rotation with the inner rotating shaft 750, and the active external threaded tube 7414 rotates relative to the transition gear 7413. Since the gear teeth of the driven gear 7412 and the transition gear 7413 are inclined, the longitudinal rotational power provided by the active external threaded tube 7414 is converted into lateral rotational power, thereby driving the lateral external pulling piece 7411 to transmit horizontally for weft straightening.

[0095] In the embodiment of the present invention, please refer to Figure 8 and Figure 9 : The transverse external pulling member 741 is composed of a plurality of rotating disks 7411 distributed in a circular array around the active external threaded tube 7414;

[0096] The rotating disk 7411 is flatly arranged in the radial direction of the driving externally threaded tube 7414. The rotating disks 7411 and the driven gears 7412 are arranged in a cross-ring array around the driving externally threaded tube 7414. The rotating disks 7411 and the driven gears 7412 are rotatably connected via a universal shaft 7415.

[0097] The outer edge of the turntable 7411 is arranged in an arc shape.

[0098] After the support roller 730 rotates relative to the inner rotating shaft 750, the active external threaded tube 7414 rotates relative to the transition gear 7413. Since the gear teeth of the driven gear 7412 and the transition gear 7413 are tilted, the longitudinal rotational power provided by the active external threaded tube 7414 is converted into transverse rotational power, thereby driving the multiple turntables 7411 on the transverse external pulling member 741 to transmit transversely for weft straightening; since the multiple unit external pulling weft straightening structures 740 transmit transversely for weft straightening on the basis of the overall longitudinal transmission, the stable longitudinal forward transmission of the base cloth and the all-round high coverage transverse weft straightening of the base cloth are achieved, thereby improving the stable weft straightening effect; since the outer edge of the turntable 7411 is arranged in an arc shape, the loss of base is avoided.

[0099] The working principle of the present invention is:

[0100] After the cylinder controls the driving roller 820 to be raised and lowered, the height adjustment of multiple tension straightening rollers is controlled, that is, the first tension straightening roller 800, the second tension straightening roller 900 and the third tension straightening roller 1000 are staggered to different degrees, and the driving roller 820 is used to pull the base fabric forward to complete the tension adjustment of the base fabric during the weft straightening process, so as to cope with the elastic changes of the base fabric itself in the continuous traction state, and avoid the situation where secondary weft skew occurs when continuing to pull after weft straightening; in the process of the driving roller 820 rotating and pulling the base fabric forward, the base fabric limiting mechanism 810 is used to limit the base fabric from both sides to achieve stable forward transmission of the base fabric, and avoid the problem of uneven hot melt adhesive caused by the fabric being continuously in the traction state, even after adjustment;

[0101] Multiple automatic telescopic rods A8322 can be adjusted in length to accommodate base fabrics of different sizes, ensuring stable forward transmission of the base fabric.

[0102] The rotational power provided by the weft straightening chassis 1 drives the rack ring and the support roller 730 to rotate, forming a relative rotation with the inner rotating shaft 750. The inner rotating shaft 750 at the end of the support roller 730 forms a symmetrical shape on both sides. By triggering the transverse rotation driving member, the transverse outer pulling member 741 is driven to rotate transversely to perform transverse weft straightening of the base cloth, so that the support roller 730 synchronously drives the multiple unit outer pulling weft straightening structures 740 to rotate and transmit the base cloth longitudinally forward, while utilizing the multiple unit outer pulling weft straightening structures 740 themselves to transmit transversely, thereby completing stable transverse weft straightening of the base cloth; because the multiple unit outer pulling weft straightening structures 740 perform weft straightening by themselves transversely on the basis of the overall longitudinal transmission, a full-range high-coverage transverse weft straightening base cloth is achieved on the basis of stable longitudinal forward transmission of the base cloth, thereby improving the stable weft straightening effect; at the same time, the longitudinal weft straightening base cloth with different degrees of staggered distribution of the first-level tension weft straightening roller 800, the second-level tension weft straightening roller 900 and the third-level tension weft straightening roller 1000 cooperate to achieve the purpose of coping with wrinkles in different directions at multiple locations of the base cloth;

[0103] After the support roller 730 rotates relative to the inner rotating shaft 750, the active external threaded tube 7414 rotates relative to the transition gear 7413. Since the gear teeth of the driven gear 7412 and the transition gear 7413 are tilted, the longitudinal rotational power provided by the active external threaded tube 7414 is converted into transverse rotational power, thereby driving the multiple turntables 7411 on the transverse external pulling member 741 to transmit transversely for weft straightening; since the multiple unit external pulling weft straightening structures 740 transmit transversely for weft straightening on the basis of the overall longitudinal transmission, the stable longitudinal forward transmission of the base cloth and the all-round high coverage transverse weft straightening of the base cloth are achieved, thereby improving the stable weft straightening effect; since the outer edge of the turntable 7411 is arranged in an arc shape, the loss of base is avoided.
