Description

Technical Field

[0001] This invention belongs to the field of weaving equipment technology, and specifically relates to a pretreatment device for a base fabric circular loom. Background Technology

[0002] The plastic weaving industry is an important part of my country's light industry, widely used in packaging, building materials, agriculture, chemicals, and other fields. As the core equipment in plastic weaving production, the circular loom's operational stability and product quality directly determine the efficiency and profitability of the entire production line. To improve the weaving quality and production efficiency of circular looms, the industry commonly uses pre-treatment devices to process the yarns used for weaving, mainly including tension adjustment, static elimination, dust removal, and wetting. Most existing pre-treatment devices adopt a distributed design, with each processing unit independently set up and installed in different locations on the production line. While this design can achieve basic pre-treatment functions, it suffers from problems such as large footprint, complex installation and debugging, and poor coordination between processes, making it difficult to meet the needs of modern plastic weaving enterprises for large-scale, continuous production.

[0003] As market demands for the quality of woven plastic products continue to rise, the limitations of existing pretreatment devices are becoming increasingly apparent.

[0004] On the one hand, existing equipment cannot effectively eliminate the internal stress generated during the yarn drawing process, which makes the woven base fabric prone to shrinkage and deformation, requiring an additional heat setting process, which increases production costs and production cycle.

[0005] On the other hand, existing devices have limited effectiveness in treating surface fuzz on yarns. Most of them use air blowing to remove dust, which can only remove surface fuzz and cannot fundamentally solve the problem of fuzz shedding. This not only affects the appearance quality of the base fabric, but also reduces the adhesion of subsequent coating processes, making the coating easy to peel off.

[0006] In addition, the existing pretreatment equipment has uneven wetting effect, which can easily lead to local over-wetting or over-drying, affecting the flexibility and breakage resistance of the yarn, resulting in a high yarn breakage rate during weaving and affecting production efficiency. Summary of the Invention

[0007] In view of the problems raised in the background art above, the object of the present invention is to provide a pretreatment device for a base fabric circular loom.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A pretreatment device for a base fabric circular loom includes a housing, a plurality of fuma wheels are installed at the bottom of the housing, and an inlet plate with a plurality of inlet guide holes is fixedly installed at one end of the housing. The box is equipped with infrared heating tubes for preheating the yarn, arranged sequentially along the yarn's direction of travel. Atomizing nozzle assembly and parallel electrode plate for directional wetting of yarn; Simulated braiding guide roller assembly used to simulate the release of internal stress in yarns during the braiding process; Low-temperature plasma generator for activating yarn surfaces; Heated roller assembly for fusing surface hairs in yarn; Cold air cooling unit for rapidly cooling and shaping yarns; A cable outlet plate with multiple cable outlet guide holes is fixedly installed at the other end of the box.

[0009] Furthermore, the side of the enclosure is provided with at least one maintenance door, which is hinged to the enclosure via a hinge. The maintenance door is equipped with at least two door latches and at least two door handles. The maintenance door structure with door latches and door handles facilitates maintenance and repair of the device by operators without disassembling the entire enclosure, thus shortening equipment downtime and improving production efficiency.

[0010] Furthermore, the infrared heating tube assembly includes multiple infrared heating tubes symmetrically arranged on the upper and lower sides of the yarn's forward direction. The length of all infrared heating tubes is equal to the internal width of the housing. The infrared heating tubes are arranged symmetrically, which can uniformly heat the yarn, avoid the problem of uneven temperature caused by single-sided heating, and ensure that the preheating effect of all yarns is consistent.

[0011] Furthermore, the atomizing nozzle assembly includes multiple elongated water pipes symmetrically arranged vertically, with multiple atomizing nozzles evenly installed on each water pipe. The water pipes are located on the upper and lower sides of the yarn path, respectively. The atomizing nozzle assembly adopts a vertically symmetrical elongated water pipe structure, which can spray the yarn simultaneously from both upper and lower directions, improving the uniformity of wetting and the coverage area.

[0012] Further defined, the parallel electrode plate includes two rectangular stainless steel plates arranged symmetrically on the top and bottom. The two stainless steel plates are located on the top and bottom sides of the yarn path, respectively, and an electric field action area is formed between the two stainless steel plates. The parallel electrode plate adopts a symmetrical rectangular stainless steel plate structure, which can generate a uniform high-voltage electric field, so that the atomized water droplets are uniformly charged and move in a direction, thereby achieving uniform wetting of the yarn inside and out.

[0013] Furthermore, the simulated weaving guide roller group includes multiple stainless steel guide rollers of the same diameter, arranged in an alternating manner, with odd-numbered guide rollers located above the yarn path and even-numbered guide rollers located below the yarn path. The center distance between two adjacent guide rollers is equal, which can accurately simulate the movement trajectory of the warp yarn in a circular loom, allowing the yarn to complete stress release in the pretreatment stage, fundamentally solving the problem of base fabric shrinkage and deformation.

[0014] Furthermore, the low-temperature plasma generator includes two cuboid plasma generating boxes arranged symmetrically on top of each other, with the openings of the two generating boxes facing each other. The yarn passes through the gap between the two generating boxes. The low-temperature plasma generator adopts a symmetrical cuboid generating box structure, which can simultaneously activate the upper and lower surfaces of the yarn, improving the uniformity and comprehensiveness of the activation effect.

[0015] Furthermore, the heating roller assembly includes a lower heating roller and an upper pressure roller arranged vertically. The lower heating roller is a mirror-finished stainless steel roller with an internal heating element, and the upper pressure roller is a rubber roller with a silicone layer on its surface. This ensures the uniformity and stability of heating, and also makes the pressing gentler, avoiding damage to the yarn.

[0016] Furthermore, the two ends of the upper pressure roller are installed in the sliding bearing seat. A pressure adjusting spring and an adjusting handwheel are provided above the sliding bearing seat. Rotating the adjusting handwheel adjusts the pressure between the upper pressure roller and the lower heating roller. The pressure between the pressure rollers can be flexibly adjusted according to the yarn of different specifications and materials, ensuring the consistency of the hair fusion effect.

[0017] Further, it also includes a PLC controller and a touch screen. The PLC controller is electrically connected to the infrared heating tube group, the atomizing nozzle group, the parallel electrode plate, the low-temperature plasma generator, the heating pressure roller group, and the cold air cooling unit, respectively. The touch screen is installed on the outer surface of the housing and can realize centralized control and real-time adjustment of all pretreatment parameters, thereby improving the automation level and ease of operation of the device.

[0018] The beneficial effects of using the present invention are as follows: The pretreatment device for the base fabric circular loom provided by the present invention integrates multiple functional units such as preheating, directional wetting, stress pre-release, surface activation, hair fusion and cooling and shaping into one box, realizing integrated continuous operation of yarn pretreatment, reducing the footprint of the device and simplifying the installation and commissioning process.

[0019] The structural design of this invention, combining infrared heating with electric field-induced directional wetting, improves the uniformity and penetration of yarn wetting, significantly enhancing yarn flexibility and effectively reducing yarn breakage during weaving. By simulating the stress pre-release of the yarn using weaving guide rollers, the shrinkage rate of the base fabric can be reduced to below 0.3%, eliminating the need for subsequent heat setting, shortening the production cycle, and lowering production costs.

[0020] The structural design of this invention, through a combination of low-temperature plasma activation and heated roller fusion, achieves permanent removal of surface fuzz from the yarn, improving the surface smoothness of the base fabric and the adhesion of subsequent coatings, thus significantly enhancing product quality. The cold air cooling unit enables rapid cooling and shaping of the yarn under stress-free conditions, ensuring dimensional stability of the product.

[0021] This device can effectively improve the production efficiency and product quality of circular looms, reduce production costs, and has good economic benefits and market application prospects. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, a pretreatment device for a base fabric circular loom of the present invention includes a housing 1, a plurality of fuma wheels 2 installed at the bottom of the housing 1, and a wire inlet plate 3 with a plurality of wire inlet guide holes 4 fixedly installed at one end of the housing 1. Inside the housing 1, infrared heating tubes 5 for preheating the yarn are arranged sequentially along the yarn advance direction; Atomizing nozzle assembly 6 and parallel electrode plate 7 for directional wetting of yarn; Simulated weaving guide roller assembly 8 is used to simulate the release of internal stress in yarns during the weaving process; Low-temperature plasma generator 9 for activating yarn surfaces; Heated roller assembly 10 for fusing surface hairs of yarn; Cold air cooling unit 11 for rapidly cooling and shaping yarns; A cable outlet plate 12 with multiple cable outlet guide holes 121 is fixedly installed at the other end of the housing 1.

[0025] In this embodiment, when using a pretreatment device for a base fabric circular loom, the yarn enters the housing 1 through the inlet guide hole 4 on the inlet plate 3. Each yarn passes through a corresponding inlet guide hole 4 and enters the first processing area in a neat arrangement. The yarn first passes through the infrared heating tube group 5, which radiates heat to the yarn, causing the overall temperature of the yarn to rise evenly. Under the action of heat, the polymer chains inside the yarn gradually break free from the binding force between molecules and change from a curled state to a relatively relaxed state. At the same time, the trace moisture and volatile impurities adsorbed on the surface of the yarn are initially removed. The yarn moves forward at a constant speed and then enters the area where the atomizing nozzle group 6 and the parallel electrode plate 7 work together. The atomizing nozzle group 6 converts liquid water into fine water mist particles with uniform particle size, which are evenly distributed in the space around the yarn. The parallel electrode plate 7 forms a stable high-voltage electric field in its area, causing the water mist particles passing through the area to carry a polar charge. Driven by the electric field force, the charged water mist particles move in a directional direction towards the yarn, which can not only adhere to the outer surface of the yarn, but also penetrate the fiber gaps on the yarn surface and enter the interior of the yarn, so that the yarn obtains a uniform wetting effect from the outside to the inside. The fully wetted yarn continues to move forward and enters the area where the simulated weaving guide roller group 8 is located. The yarn passes around each guide roller in the simulated weaving guide roller group 8 in sequence according to the preset path. During the process of passing around each guide roller, the yarn will undergo a cycle of bending deformation and stretching deformation. The frequency, amplitude and stress state of these deformation cycles are completely consistent with the deformation cycles that the yarn will undergo in the subsequent circular loom weaving process. The residual internal stress accumulated in the yarn during the previous drawing process is gradually released in these repeated deformation processes, and the molecular chains rearrange to the stable state with the lowest energy. After the internal stress is released, the yarn leaves the simulated braiding guide roller group 8 and enters the area where the low-temperature plasma generator 9 is located. The low-temperature plasma generator 9 generates high-density low-temperature plasma in the gap between its two generating boxes. The high-energy particles in the plasma collide and interact with the molecules on the yarn surface, breaking some of the chemical bonds of the yarn surface molecules and forming a large number of highly reactive free radicals and functional groups on the yarn surface. At the same time, the etching effect of the plasma can remove residual oil, auxiliaries and tiny impurities on the yarn surface, making the yarn surface cleaner and rougher. The surface-activated yarn continues to move forward and enters the area where the heated pressure roller group 10 is located. The yarn passes between the two rollers of the heated pressure roller group 10. The lower heating roller 101 transfers heat to the yarn, raising the temperature of the yarn surface to a suitable range. The hairs on the yarn surface soften under the action of heat. At the same time, the upper pressure roller 102 applies uniform pressure to the yarn, pressing the softened hairs tightly onto the surface of the yarn body. The active groups on the hair surface and the surface of the yarn body undergo a chemical reaction under the combined action of temperature and pressure, forming stable chemical bonds that permanently fix the hairs to the yarn body. The yarn that has completed the hair fusion process finally passes through the area where the cold air cooling unit 11 is located. The cold air cooling unit 11 blows clean cold air of uniform temperature onto the yarn, so that the temperature of the yarn is quickly reduced to room temperature. The molecular structure inside the yarn and the size and shape outside the yarn are fixed during the cooling process and will no longer undergo spontaneous deformation. Finally, the yarn, after all the processing steps, leaves the housing 1 through the yarn guide hole 121 on the yarn exit plate 12, and enters the weaving host of the circular loom while maintaining a stable tension and alignment. By integrating multiple pretreatment processes that originally needed to be completed on separate equipment into a single housing 1, continuous and uninterrupted yarn processing from entry to exit is achieved. Each processing process is closely linked in a specific sequence, and the processing result of the previous process provides the optimal processing conditions for the next process. The processes cooperate and promote each other, forming an organic whole. While significantly improving the pretreatment effect, the system's footprint is significantly reduced, the installation and commissioning process of the production line is simplified, and the operating and maintenance costs of the equipment are reduced.

[0026] The preferred enclosure 1 has at least one access door 13 on its side. The access door 13 is hinged to the enclosure 1 via a hinge. The access door 13 is equipped with at least two door latches 14 and at least two door handles 15.

[0027] In this embodiment, the maintenance door 13 is hinged to the side of the housing 1. The door lock 14 and the door handle 15 are respectively installed on the edge of the maintenance door 13. The operator can open the maintenance door 13 through the door handle 15 to inspect, maintain and replace the various functional units inside the housing 1. Sealing strips can be added to the edge of the inspection door 13 to improve the sealing of the box 1 and prevent dust and impurities from entering the box 1. Alternatively, a transparent observation window can be opened on the inspection door 13 to allow operators to observe the operating status inside the box 1 without opening the inspection door 13. With this structural design, operators can maintain the internal equipment without disassembling the entire housing 1, which greatly shortens the equipment downtime, improves production efficiency, and reduces the difficulty and cost of equipment maintenance.

[0028] The preferred infrared heating tube assembly 5 includes multiple infrared heating tubes symmetrically arranged on the upper and lower sides of the yarn's forward direction, and the length of all infrared heating tubes is equal to the internal width of the housing 1.

[0029] In this implementation case, the infrared heating tube group 5 is composed of multiple long strip infrared heating tubes. All infrared heating tubes are installed on the upper and lower sides of the yarn path, and are symmetrically distributed. The length of each infrared heating tube is equal to the internal width of the box 1, which can cover the width range of the entire yarn arrangement. Infrared heating tubes can be mounted on height-adjustable brackets. By adjusting the height of the brackets, the distance between the infrared heating tubes and the yarn can be changed, thereby adjusting the heating intensity. Alternatively, the infrared heating tubes can be divided into multiple independently controlled heating zones, and the heating power of each zone can be adjusted individually according to the distribution of the yarn. The symmetrical arrangement allows for simultaneous heating of both the upper and lower surfaces of the yarn, avoiding uneven temperatures caused by single-sided heating. This ensures that all yarns receive consistent preheating, laying a solid foundation for subsequent wetting and stress-relieving processes.

[0030] The preferred atomizing nozzle group 6 includes multiple long strip water pipes arranged symmetrically at the top and bottom, with multiple atomizing nozzles evenly installed on each water pipe. The water pipes are located on the upper and lower sides of the yarn path, respectively.

[0031] In this implementation case, the atomizing nozzle group 6 consists of multiple long strip water pipes, which are installed on the upper and lower sides of the yarn path in a symmetrical distribution. Multiple atomizing nozzles are evenly installed on each water pipe, and the spray direction of the atomizing nozzles is towards the yarn. A flow regulating valve can be installed at the water inlet of the water pipe to control the amount of water sprayed by the atomizing nozzles by adjusting the water flow rate. The number and spacing of the atomizing nozzles can also be adjusted according to the density of the yarn and the running speed to ensure that all yarns can be sprayed evenly. The structure uses a symmetrical, elongated water pipe that can spray the yarn from both top and bottom directions simultaneously, improving the coverage of the water mist and the uniformity of wetting, thus avoiding the problem of some yarns being under-wetted or over-wetted.

[0032] The preferred parallel electrode plate 7 includes two rectangular stainless steel plates arranged symmetrically on the top and bottom. The two stainless steel plates are located on the top and bottom sides of the yarn path, respectively, and an electric field action area is formed between the two stainless steel plates.

[0033] In this embodiment, the parallel electrode plate 7 consists of two rectangular stainless steel plates. The two stainless steel plates are installed on the upper and lower sides of the yarn path respectively, in a symmetrical distribution. The two stainless steel plates maintain a certain distance from each other to form an electric field action area. An insulating protective plate can be installed on the edge of the parallel electrode plate 7 to prevent operators from accidentally touching the electrode plate and getting an electric shock. The electric field strength can also be changed by adjusting the distance between the two electrode plates and the applied voltage to adapt to the wetting needs of yarns of different specifications. The structure uses a symmetrical rectangular stainless steel plate to generate a uniform and stable high-voltage electric field, which causes the atomized water droplets to be uniformly charged and move in a direction, penetrating the boundary layer of the yarn surface and entering the yarn interior, thus achieving uniform wetting of the yarn inside and out and improving the wetting effect.

[0034] The preferred simulated weaving guide roller group 8 includes multiple stainless steel guide rollers of the same diameter, which are arranged in an alternating manner. Odd-numbered guide rollers are located above the yarn path, and even-numbered guide rollers are located below the yarn path. The center distance between two adjacent guide rollers is equal.

[0035] In this implementation case, the simulated knitting guide roller group 8 consists of multiple stainless steel guide rollers of the same diameter. All guide rollers are arranged in an alternating manner, with odd-numbered guide rollers located above the yarn path and even-numbered guide rollers located below the yarn path. The center distance between two adjacent guide rollers is equal. A wear-resistant coating can be sprayed onto the surface of the guide rollers to improve their wear resistance and surface smoothness, reduce friction damage to the yarn, and adjust the number and arrangement of the guide rollers according to the weaving patterns of different models of circular looms to achieve the best stress release effect. This staggered arrangement accurately simulates the movement trajectory of warp yarns in a circular loom, allowing the yarns to undergo the same stress cycle as the actual weaving process during the pretreatment stage. This completely releases the residual stress inside the yarns, fundamentally solving the problem of shrinkage and deformation of the base fabric after weaving.

[0036] The preferred low-temperature plasma generator 9 includes two cuboid plasma generating boxes arranged symmetrically on top and bottom, with the openings of the two generating boxes facing each other, and the yarn passing through the gap between the two generating boxes.

[0037] In this embodiment, the low-temperature plasma generator 9 consists of two cuboid plasma generating boxes. The two generating boxes are installed on the upper and lower sides of the yarn path respectively, in a symmetrical distribution. The openings of the two generating boxes are set opposite to each other, and the yarn passes through the gap between the two generating boxes. The plasma generator box can be designed as a drawer-type structure, which makes it convenient for operators to clean and replace the electrodes inside the generator box. The distance between the two generator boxes can also be adjusted to meet the processing needs of yarns of different thicknesses. The symmetrical cuboid generating box structure allows for simultaneous activation of both the upper and lower surfaces of the yarn, improving the uniformity and comprehensiveness of the activation effect. This generates more active groups on the yarn surface, creating favorable conditions for subsequent hair fusion processes.

[0038] The preferred heating roller assembly 10 includes a lower heating roller 101 and an upper pressure roller 102 arranged vertically. The lower heating roller 101 is a mirror stainless steel roller with a heating element inside, and the upper pressure roller 102 is a rubber roller with a silicone layer on its surface.

[0039] In this embodiment, the heating roller group 10 consists of a lower heating roller 101 and an upper pressure roller 102. The lower heating roller 101 and the upper pressure roller 102 are arranged vertically. The lower heating roller 101 is a mirror stainless steel roller with a heating element inside, and the upper pressure roller 102 is a rubber roller with a silicone layer on its surface. A temperature sensor can be installed inside the lower heating roller 101 to monitor the surface temperature of the lower heating roller 101 in real time. The temperature can be precisely controlled within the set range by the control system. Silicone layers of different hardness can also be replaced according to the processing requirements of different yarn materials. With this combined structure, the lower heating roller 101 can provide a uniform and stable heating effect, while the silicone layer of the upper pressure roller 102 has good elasticity, which can make the pressing more gentle and uniform, avoid damage to the yarn, and at the same time ensure sufficient contact between the hairs and the yarn body.

[0040] Preferably, both ends of the upper pressure roller 102 are installed in the sliding bearing seat 103. A pressure adjusting spring 104 and an adjusting handwheel 105 are provided above the sliding bearing seat 103. The adjusting handwheel 105 is rotated to adjust the pressure between the upper pressure roller 102 and the lower heating roller 101.

[0041] In this embodiment, the two ends of the upper pressure roller 102 are respectively installed in the sliding bearing seat 103. The sliding bearing seat 103 can slide in the vertical direction. The pressure adjusting spring 104 is set above the sliding bearing seat 103, and the adjusting handwheel 105 is installed on the top of the pressure adjusting spring 104. A pressure sensor can be installed on the sliding bearing seat 103 to monitor the pressure between the upper pressure roller 102 and the lower heating roller 101 in real time, and the pressure can be automatically adjusted by the control system. Alternatively, a dial can be added to the adjusting handwheel 105 to facilitate operators to accurately adjust the pressure. With this pressure regulating mechanism, the operator can change the compression of the pressure regulating spring 104 by rotating the regulating handwheel 105, thereby flexibly adjusting the pressure between the upper pressure roller 102 and the lower heating roller 101 to meet the processing needs of yarns of different specifications and materials, and ensure the consistency of the hair fusion effect.

[0042] Preferably, it also includes a PLC controller 16 and a touch screen 17. The PLC controller 16 is electrically connected to the infrared heating tube group 5, the atomizing nozzle group 6, the parallel electrode plate 7, the low-temperature plasma generator 9, the heating pressure roller group 10, and the cold air cooling unit 11, respectively.

[0043] In this embodiment, the PLC controller 16 is installed inside the housing 1, and the touch screen 17 is installed on the outer surface of the housing 1. The PLC controller 16 is electrically connected to the infrared heating tube group 5, the atomizing nozzle group 6, the parallel electrode plate 7, the low temperature plasma generator 9, the heating pressure roller group 10, and the cold air cooling unit 11, respectively. The PLC controller 16 can store pretreatment process parameters for various yarn specifications. Operators only need to select the corresponding yarn specification through the touch screen 17, and the system can automatically call up the corresponding process parameters. A remote communication module can also be added to realize remote monitoring and operation of the device. The control system, consisting of a PLC controller 16 and a touch screen 17, enables centralized control and real-time adjustment of all preprocessing parameters, improving the automation level and ease of operation of the device, reducing manual intervention, and lowering the labor intensity of operators.
