Description

Technical Field

[0001] The utility model relates to a loom system, in particular to a film-coated woven cloth production system for weaving chemical fiber yarns after film coating. Background Art

[0002] Chemical fiber is a by-product of the modern petroleum industry. It is widely used in the textile industry and processed into daily textile items such as clothing, tents, ropes, etc. The more mainstream chemical fibers include polyester, nylon and other products. The diameter of chemical fiber ranges from a few microns to hundreds of microns, and it is woven into yarn according to the application, and then the yarn is woven into cloth; or blended with cotton yarn to form cloth, etc. The electrical, physical and chemical properties of chemical fiber fabrics are determined by the properties of chemical fiber and reflected by the macroscopic properties of chemical fiber microscopic properties. In today's chemical and textile industries, chemical bleaching and printing are the basic methods to change the color and finished product characteristics of chemical fiber at the microscopic and macroscopic levels. The advantages of these processes are low equipment and process investment costs, but the disadvantage is that the coating is too thick, ranging from a few microns to tens of microns, which is at the same order of magnitude as the diameter of the chemical fiber. Therefore, it is inevitable to cause changes in the mechanical properties of chemical fiber, making chemical fiber yarns not soft, light-proof, and heat-proof, and unable to meet the needs of high-end applications. In addition, many new materials such as silicon, tin oxide, diamond-like carbon coating (DLC), silicon nitride, titanium nitride and other new materials cannot be coated on the fiber by chemical dyeing or printing technology. Therefore, the use of existing technical means to coat chemical fiber yarns will double the size of chemical fiber yarns, the coating layer has poor adhesion, and the mechanical properties are changed; using it to produce cloth, due to its size, poor adhesion of the coating layer and changes in mechanical properties, on the one hand, it is difficult for existing looms to weave cloth, and on the other hand, even if the existing looms can weave cloth, the cloth produced by them is difficult to achieve the expected effect (most of the coating layer will fall off, resulting in the size and performance of the produced cloth being difficult to achieve the expected effect), resulting in unqualified quality.

[0003] Therefore, there is an urgent need to provide a coated woven fabric production system that can produce coated woven fabrics, the produced coated woven fabrics can achieve the expected effect, and the physical and chemical properties can add new functions on the basis of maintaining the original mechanical properties. Utility Model Content

The produced coated woven fabrics can achieve the expected effect, and the physical and chemical properties increase new functions on the basis of maintaining the original mechanical properties.

[0005] To achieve the above-mentioned purpose, the utility model provides a coated woven fabric production system, which comprises:

[0006] A PECVD coating device for generating plasma, wherein the PECVD coating device is provided with an ionized glow region for generating plasma, and the ionized glow region is provided with a plurality of outlets;

[0007] The chemical fiber yarn transmission unit is arranged side by side and corresponds to the outlet one by one, and the chemical fiber yarn transmission unit includes an unwinding chamber, a first tension chamber, a deposition chamber, a second tension chamber and a traction chamber which are arranged in sequence from left to right; a rotatable unwinding wheel with chemical fiber yarn wound on it is provided in the unwinding chamber; the first tension chamber is connected to the unwinding chamber, and at least two rotatable first tension wheels with a certain damping relative to the chemical fiber yarn are provided in the first tension chamber, and the first tension wheels are staggered; the chemical fiber yarn unwound by the unwinding chamber is wound around the first tension wheel in turn for tightening; the deposition chamber is connected to the first tension chamber, and a device for tightening the chemical fiber yarn delivered to the first tension chamber is provided in the deposition chamber. A deposition box for depositing and coating yarns, wherein the deposition box is a hollow structure, wherein the hollow structure forms a deposition chamber, wherein the deposition chamber is connected to the outlet of the ionized glow zone; the second tension chamber is connected to the deposition chamber, wherein at least two rotatable second tension wheels having a certain damping relative to the coated chemical fiber yarns are arranged in the second tension chamber, wherein the second tension wheels are staggered; the chemical fiber yarns that have completed deposition and coating in the deposition chamber are sequentially wound around the second tension wheels for tightening; the traction chamber is connected to the second tension chamber, wherein a traction wheel for traction of the chemical fiber yarns from the unwinding wheel is arranged in the traction chamber, wherein the coated chemical fiber yarns are wound around the traction wheel for one circle;

[0008] A loom for weaving warp and weft, the loom comprising a carrier, a weft axis, a shuttle, a warp axis, a transmission roller, a heald structure, a first drive mechanism and a second drive mechanism; the weft axis is rotatably arranged on the carrier, the coated chemical fiber yarn on one of the traction wheels is led to the weft axis and wound around once to form a weft, and the weft is connected to the shuttle; the warp axis is rotatably arranged on the carrier, the coated chemical fiber yarn on the other traction wheels is led to the warp axis and wound around once to form a warp, each of the warp axis corresponds to one of the traction wheels, the warps are arranged side by side and parallel in the longitudinal direction, and each of the warps is wound around the transmission roller once; The transmission roller is rotatably arranged on the supporting platform and is rotatably connected to the first driving mechanism, the first driving mechanism drives the transmission roller to rotate, and the rotation of the transmission roller drives the warp to move longitudinally; the heald structure is arranged on the supporting platform, the warp passes through the heald structure accordingly, the lifting and lowering of the heald structure divides the warp into two staggered upper and lower groups, and the intersection of the upper and lower groups of warp forms a shed; the shuttle is connected to the second driving mechanism, the second driving mechanism drives the shuttle to make a transverse reciprocating motion in the shed, and the transverse reciprocating motion of the shuttle quickly moves the weft to the upper and lower staggered warp to weave the warp and weft to form a coated woven cloth.

[0009] Compared with the prior art, when the utility model is implemented, the chemical fiber yarn on the unwinding wheel passes through the deposition chamber of the deposition box horizontally under the traction of the traction wheel. The deposition chamber is connected to the ionized glow zone of the plasma generated by the PECVD coating device. Therefore, the deposition chamber will deposit and coat the chemical fiber yarn passing through it, so that the surface of the chemical fiber yarn is covered with a uniform film layer, thereby completing the coating of the chemical fiber yarn. Since the PECVD coating device is used to deposit and coat the chemical fiber yarn, the film thickness is nanometer-level and has strong adhesion. The size and specification of the chemical fiber yarn after coating are basically the same as the size and specification of the chemical fiber yarn before coating, so that the physical and chemical properties of the chemical fiber yarn after coating are maintained while maintaining the original mechanical properties. At the same time, the new functions corresponding to the film layer material are added. The chemical fiber yarn after coating is distributed on the weft axis and the warp axis of the loom according to the requirements to form the weft and warp. The weft is woven under the action of the heald structure and the transmission roller, and the warp is woven under the action of the shuttle to form a coated woven cloth. Since the coated woven fabric of the utility model is woven by the chemical fiber yarn formed by the above-mentioned coating, the film layer of the coated woven fabric will not fall off, and the size and specification are basically the same as the fabric formed by the chemical fiber yarn without coating in the same weaving method. Therefore, the coated woven fabric produced by the coated woven fabric production system of the utility model can achieve the expected effect, and the physical and chemical properties add new functions on the basis of maintaining the original mechanical properties, and the added new functions are the functions corresponding to the film layer material. It is worth noting that since the size and specification of the chemical fiber yarn after coating are basically the same as the size and specification of the chemical fiber yarn before coating, and the film layer has strong adhesion ability, the loom can adopt the existing loom, so that the utility model can realize the production of coated woven fabric for chemical fiber yarn after coating by adopting the existing loom.

[0024] like Figure 1 - Figure 3As shown, the coated woven fabric production system 100 of the utility model includes a PECVD coating device 1, a chemical fiber yarn transmission unit 2 and a loom 3. The PECVD coating device 1 of the utility model is used to generate plasma. The plasma generated by the PECVD coating device 1 is used to deposit the coating on the chemical fiber yarn to form a coating layer. The corresponding process gas is introduced into the PECVD coating device 1 as required, and the process gas is ionized to generate plasma. The PECVD coating device 1 of the utility model is provided with an ionized glow zone 11 for generating plasma, and the ionized glow zone 11 is provided with a plurality of outlets 12. The chemical fiber yarn transmission unit 2 of the utility model is used to transmit the chemical fiber yarn for coating and transport it to the loom 3. The number of the chemical fiber yarn transmission units 2 is corresponding to the number of the outlets 12 of the PECVD coating device 1. The chemical fiber yarn transmission units 2 of the utility model are arranged side by side with each other, and each chemical fiber yarn transmission unit 2 transmits and coats one chemical fiber yarn. The PECVD coating device 1 of the utility model provides plasma for deposition coating for all chemical fiber yarns transmitted by the chemical fiber yarn transmission unit 2. The loom 3 of the utility model adopts the principle of warp and weft weaving, and its warp and weft are formed by chemical fiber yarns passing through the chemical fiber yarn transmission unit 2 for deposition coating; the warp and weft structures, specifications and sizes are exactly the same, but the distribution positions of the two in the cloth are different. The loom 3 of the utility model weaves the chemical fiber yarns after coating in warp and weft to form coated woven cloth.

[0025] like Figure 1As shown, the chemical fiber yarn transmission unit 2 of the utility model is arranged side by side and corresponds to the outlet of the PECVD coating device 1 one by one. The chemical fiber yarn transmission unit 2 of the utility model includes an unwinding chamber 21, a first tension chamber 22, a deposition chamber 23, a second tension chamber 23 and a traction chamber 25 arranged in sequence from left to right. The unwinding chamber 21 of the utility model is used to provide an output source of the chemical fiber yarn required for coating; the first tension chamber 22 and the second tension chamber 23 of the utility model are used to ensure that the chemical fiber yarn 200 before coating and the chemical fiber yarn 200a after coating are in a taut state during the coating transmission process to prevent falling off and entanglement; the deposition chamber 23 of the utility model is used to perform plasma deposition coating on the chemical fiber yarn 200 to form a film layer. Specifically, a rotatable unwinding wheel 211 with the chemical fiber yarn 200 wound thereon is provided in the unwinding chamber 21 of the utility model. The first tension chamber 22 of the utility model is connected to the unwinding chamber 21, and at least two rotatable first tension wheels 221 with a certain damping relative to the chemical fiber yarn 200 are arranged in the first tension chamber 22. The first tension wheels 221 are staggered, and the chemical fiber yarn 200 unwound from the unwinding chamber 21 is sequentially wound around the first tension wheels 221 for tightening; the first tension wheel 221 has a certain damping and staggered setting for the chemical fiber yarn 200, which further ensures that the chemical fiber yarn 200 being transmitted is kept taut during the transmission process, preventing it from falling off and being entangled and knotted. The deposition chamber 23 of the utility model is connected to the first tension chamber 22. The deposition chamber 23 of the utility model is provided with a deposition box 231 for depositing and coating the chemical fiber yarn 200 delivered to the first tension chamber 22. The deposition box 222 is a hollow structure, and the hollow structure forms a deposition cavity 232. The deposition cavity 232 is connected to the outlet 12 of the ionization glow zone 11 of the PECVD coating device 1; specifically, the deposition cavity 232 is connected to the outlet 12 of the ionization glow zone 11 through a pipeline. Since each deposition cavity 232 only needs to correspond to one chemical fiber yarn transmission unit 2 The chemical fiber yarn 200 being transported is subjected to transmission-type deposition coating (i.e., deposition coating while being transported), so the volume of the deposition chamber 232 is relatively small and the amount of plasma in the deposition chamber 232 is also relatively small, but the length for the chemical fiber yarn 200 to pass through needs to be longer, and the concentration of isomorphs therein needs to be greater; usually, a negative pressure device is provided on the passage from the ionization glow zone 11 to the deposition chamber 232, and the negative pressure device is used to accelerate the plasma in the ionization glow zone 11 through the outlet 12 and enter the deposition chamber 232, so that the concentration of isomorphs in the deposition chamber 232 is greater.Based on the above factors, the deposition chamber 232 of the utility model is connected to the outlet 12 of the ionization glow zone 11 through a pipeline to transmit plasma, which will also affect the coating effect of a chemical fiber yarn 200 in and out of the transmission-type deposition coating, and effectively realizes a process in which the plasma generated by a PECVD coating device 1 is in a multi-branch manner for the chemical fiber yarns 200 transmitted by multiple chemical fiber yarn transmission units 2 to be deposited and coated at the same time, which greatly reduces the setting of the PECVD coating device 1, saves costs, simplifies the structure and process, and has strong practicality. The second tension chamber 24 of the utility model is connected to the deposition chamber 23, and at least two rotating second tension wheels 241 with a certain damping relative to the coated chemical fiber yarn 200a are arranged in the second tension chamber 24, and the second tension wheels 241 are staggered; the chemical fiber yarn 200a that has completed the deposition and coating in the deposition chamber 23 is sequentially wound around the second tension wheels 241 for tightening; the second tension wheel 241 of the utility model has a certain damping and staggered setting for the coated chemical fiber yarn 200a, which further ensures that the transmitted coated chemical fiber yarn 200a remains taut during the transmission process, preventing it from falling off and entangled and knotted. The traction chamber 25 of the utility model is connected to the second tension chamber 24. A traction wheel 251 is provided in the traction chamber 25 for traction of the chemical fiber yarn to be unwound from the unwinding wheel 211. The coated chemical fiber yarn 200a is wound around the traction wheel 251 for one circle. The setting of the traction wheel 251 effectively enables the chemical fiber yarn 200 to be unwound from the unwinding wheel 211 to maintain the continuous production of coated woven cloth of the utility model; the traction wheel 251 cooperates with the first tension wheel 221 and the second tension wheel 241 to further ensure the stability of the transmission of the chemical fiber yarn in the chemical fiber yarn transmission unit 2 and prevent it from falling off, entanglement or knotting.

[0026] Combination Figure 1 - Figure 3As shown, the loom 3 of the utility model is used to weave the coated chemical fiber yarn 200a output by the chemical fiber yarn transmission unit 2 in warp and weft to form the required coated woven cloth. Specifically, the loom 3 of the utility model includes a carrier 31, a weft axis 32, a shuttle 33, a warp axis 34, a transmission roller 35, a heald structure 36, a first driving mechanism 37 and a second driving mechanism 38. The weft axis 32 of the utility model is rotatably arranged on the carrier 31. The coated chemical fiber yarn 200a on one of the traction wheels 251 in all the chemical fiber yarn transmission units 2 of the utility model is led to the weft axis 32 and wound around to form a weft 4a, and the weft 4a is connected to the shuttle 33. The warp axis 34 of the utility model is rotatably disposed on the support platform 31. Except for the traction wheel 251 corresponding to the weft axis 32, the coated chemical fiber yarn 200a on the traction wheel 251 of the other chemical fiber yarn transmission units 2 is led to the warp axis 34 and wound around to form the warp 4b. Each warp axis 34 of the utility model corresponds to a traction wheel 251. The warp 4b of the utility model is distributed side by side and parallel in the longitudinal direction. Each of the warp 4b is wound around a drive roller 35. The drive roller 35 is rotatably disposed on the support platform 31 and is rotatably connected to the first drive mechanism 37. The first drive mechanism 37 of the utility model drives the drive roller 35 wound with the warp 4b to rotate, and the rotation of the drive roller 35 drives the warp 4b to move in the longitudinal direction. Figure 2 The direction indicated by A is the longitudinal direction. The heald structure 36 of the utility model is arranged on the supporting platform 31, and the warp 4b passes through the heald structure 36 accordingly. The lifting and lowering of the heald structure 36 divides the warp 4b into two staggered upper and lower groups, and the staggered part of the upper and lower groups of warp 4b forms a shed. The shuttle 33 of the utility model is connected to the second driving mechanism 38, and the second driving mechanism 38 drives the shuttle 38 to make a lateral reciprocating motion in the shed formed by the staggered part of the upper and lower groups of warp 4b. The lateral reciprocating motion of the shuttle 38 quickly moves the weft 4a to the upper and lower staggered warp 4b to perform warp and weft weaving to form a coated woven cloth 300. In order to improve the production efficiency of the coated woven cloth 300, the shuttle 33 of the utility model is a sword needle structure.

[0027] Combination Figure 1 - Figure 3As shown, when the utility model is implemented, the chemical fiber yarn 200 on the unwinding wheel 211 passes horizontally through the deposition chamber 232 of the deposition box 231 under the traction of the traction wheel 251. The deposition chamber 232 is connected to the ionized glow zone 11 where the plasma is generated by the PECVD coating device 1. Therefore, the deposition chamber 232 will deposit and coat the chemical fiber yarn 200 passing therethrough, so that the surface of the chemical fiber yarn 200 is covered with a uniform film layer, thereby completing the coating of the chemical fiber yarn. Since the PECVD coating device 1 is used to deposit and coat the chemical fiber yarn 200, the film layer thickness is nanometer-level and has strong adhesion. The size and specifications of the chemical fiber yarn 200a after coating are basically equivalent to the size and specifications of the chemical fiber yarn before coating, so that the physical and chemical properties of the chemical fiber yarn 200a after coating are maintained while maintaining the original mechanical properties, and also increase the new functions corresponding to the film layer material. The coated chemical fiber yarn 200a is distributed on the weft axis 32 and the warp axis 34 of the loom 3 as required to form the weft 4a and the warp 4b, and the weft 4a is woven under the action of the heald structure 36 and the transmission roller 35, and the warp 4b is woven under the action of the shuttle 33 to form the coated woven cloth 300. Since the coated woven cloth 300 of the utility model is woven by the chemical fiber yarn 200a formed by the above-mentioned coating, the film layer of the coated woven cloth 300 will not fall off, and the size and specification are basically the same as the cloth formed by the chemical fiber yarn without coating in the same weaving method; therefore, the coated woven cloth 300 produced by the coated woven cloth production system of the utility model can achieve the expected effect, and the physical and chemical properties have new functions added on the basis of maintaining the original mechanical properties, and the added new functions are the functions corresponding to the film layer material. It is worth noting that, in the present invention, since the size and specification of the chemical fiber yarn 200a after coating are basically the same as those of the chemical fiber yarn before coating, and the film layer has strong adhesion ability, the loom 3 can be an existing loom, so that the present invention can produce the coated woven fabric 300 for the chemical fiber yarn 200a after coating using an existing loom. In order to further improve the working efficiency and performance of the coated woven fabric production system 100 of the present invention and the quality of the produced coated woven fabric 300, the present invention has further made the following improvements:

[0028] like Figure 1 and Figure 3As shown, the PECVD coating device 1 of the coating woven fabric production system 100 of the present invention includes an electrode plate 13, a gas distribution box 14, an insulating enclosure 15 and a power supply 16. Specifically, the gas distribution box 14 of the present invention is used to release plasma in the deposition cavity 223 of the deposition box 222 of the deposition chamber 22. The gas distribution box 14 is a conductive hollow structure, and the hollow structure forms a plasma gathering cavity 17; the gas distribution box 14 is parallel to and directly opposite to the electrode plate 13, and the electrode plate 13 is located directly above the gas distribution box 14. The insulating enclosure 15 of the present invention is arranged around the boundary between the electrode plate 13 and the top 14a of the gas distribution box 14, and the area between the electrode plate 13 and the top 14a of the gas distribution box 14 is enclosed by the insulating enclosure 15 to form a closed ionized glow zone 11. The two poles of the power supply 16 are electrically connected to the electrode plate 13 and the gas distribution box 14 respectively. The right side of the ionized glow zone 11 of the PECVD coating device 1 of the utility model is provided with an air inlet 18 for process gas to enter, and the left side of the ionized glow zone 11 is provided with an air outlet 19 for the plasma generated by ionization to enter the plasma gathering chamber 17. The air distribution box 14 is connected with the ionized glow zone 11 through the air outlet 19, so that the plasma generated by the ionized process gas in the ionized glow zone 11 enters the plasma gathering chamber 17 from the air outlet 19 for gathering and uniform distribution of concentration. After the plasma is gathered in the plasma gathering chamber 17 and uniformly distributed in concentration, it is transported to the deposition chamber 223 of the deposition box 222 of the deposition chamber 22 of each chemical fiber yarn transmission unit 2 through the outlet 12 opened thereon through the pipeline, thereby realizing the transmission-type deposition coating of the chemical fiber yarn 200 that crosses the deposition chamber 223. As can be seen from the above, the utility model sets an ionization glow zone 11 and a plasma gathering chamber 17 that are interconnected and independent, so that the ionization glow zone 11 only ionizes the process gas; the plasma generated by the ionization enters the plasma gathering chamber 17 of the gas distribution box 14, and the plasma is buffered and gathered in the plasma gathering chamber 17 of the gas distribution box 14, so that the concentration of the plasma in the plasma gathering chamber 17 is more uniform, and then the concentration and speed of the plasma transported from the plasma gathering chamber 17 to the deposition chamber 223 of each chemical fiber yarn transmission unit 2 are relatively consistent, ensuring the consistency of the coating of the ionized gas deposited on the chemical fiber yarn 200. Therefore, the ionization and deposition of the utility model are completed in independent areas respectively, effectively avoiding the occurrence of technical problems of plasma attacking the surface of the deposited film, and substantially solving the technical problem of the deposited film being attacked and causing serious defects caused by the simultaneous ionization and deposition of gas in the ionization glow zone in the prior art, ensuring the stability of the nano-scale film layer formed by coating on the micron-scale chemical fiber yarn 200.At the same time, since the ionization glow zone 11 of the utility model is only used for gas ionization, and the gas distribution box 14 is only used for buffering, gathering and adjusting the uniformity of plasma daughter body concentration, the deposition chamber 223 is only used for the chemical fiber yarn 200 to pass through and deposit the coating. This indirect PECVD deposition method makes the utility model more sufficient for gas ionization and the thin film deposited on the chemical fiber yarn 200 is more uniform, which not only makes full use of the ionized gas, but also ensures the uniformity of the deposited film, greatly improves the quality and adhesion of the deposited film, and further makes the physical and chemical properties of the chemical fiber yarn 200a after coating maintain the original mechanical properties while adding new functions corresponding to the film layer material; obviously, the coated woven cloth 300 produced by the coated woven cloth production system of the utility model can achieve the expected effect, and the physical and chemical properties add new functions on the basis of maintaining the original mechanical properties, and the added new functions are the functions corresponding to the film layer material.

[0029] like Figure 1 As shown, the first tension wheel 221 and the second tension wheel 241 of the coated woven fabric production system 100 of the utility model have the same structure, and the layout of the first tension wheel 221 in the first tension chamber 22 and the layout of the second tension wheel 241 in the second tension chamber 24 are symmetrical with respect to the deposition chamber 23. The first tension wheel 221 and the second tension wheel 241 have the same structure and the layout is symmetrical with respect to the deposition chamber 23, which effectively ensures that the speed of the chemical fiber yarn 200 from unwinding to traction is consistent during the entire transmission process, and ensures that the chemical fiber yarn 200 will not be knotted; on the other hand, it is also convenient for manufacturing and installation, saving costs.

[0030] like Figure 1As shown, a first opening 1-1 is provided between the deposition chamber 23 and the first tension chamber 22 of the coated woven fabric production system 100 of the present invention for the chemical fiber yarn 200 to pass through, a second opening 1-2 is provided on the left side of the deposition box 231 opposite to the first opening 1-1, a third opening 1-3 is provided on the right side of the deposition box 231 opposite to the second opening 1-2, and a fourth opening 1-4 is provided between the second tension chamber 24 and the deposition chamber 23 opposite to the third opening 1-3; the second opening 1-2 and the third opening 1-3 penetrate the deposition cavity 232 of the deposition box 231, the chemical fiber yarn 200 passing through the first opening 1-1 enters the deposition cavity 232 of the deposition box 231 through the second opening 1-2 for deposition and coating, and the chemical fiber yarn 200a that has completed coating passes through the deposition cavity 232 through the third opening 1-3 and enters the second tension chamber 24 through the fourth opening 1-4. Specifically, in order to ensure the stability of the transmission of the chemical fiber yarn 200, the first opening 1-1, the second opening 1-2, the third opening 1-3 and the fourth opening 1-4 are located on the same horizontal line.
