A waterless flannel fabric impregnation system and its manufacturing process

Abstract

This invention relates to the field of padding technology, and particularly to a padding system and its production process for waterless flannel fabrics. The system comprises, in sequence, a traction assembly, a padding assembly, and a drying assembly. The traction assembly controls the fabric as it passes through the padding assembly and the drying assembly. The drying assembly has at least a drying zone and a compression zone, and the traction assembly has at least a first traction zone and a second traction zone. The fabric moves between the padding assembly, the compression zone, and the drying zone under the control of the first traction zone and / or the second traction zone. When the fabric enters the compression zone from the padding assembly, the compression zone compresses the fabric and squeezes out excess slurry. Under the control of the first traction zone and / or the second traction zone, the fabric then enters the drying zone for drying. This invention improves the padding effect by preheating before padding and squeezing after padding followed by drying, thereby squeezing out excess slurry and allowing the slurry to penetrate the fabric during squeezing.

Description

Technical Field

[0001] This invention relates to the field of impregnation technology, and in particular to an impregnation system and production process for waterless flannel fabrics. Background Technology

[0002] Flannel is a soft, piled cotton-wool fabric made of coarse cotton yarn, which has the advantages of being very soft, comfortable, and warm.

[0003] Therefore, as people's living standards improve, their requirements and demands for clothing, housing, and other aspects are constantly being innovated. Flannel, due to its comfort and other advantages, is now also used to make various home textile and clothing products such as blankets, pajamas, and duvet covers.

[0004] Currently, the production process of flannel is relatively mature, and it usually involves several steps such as material selection, warping, weaving and splitting, and padding (see authorization announcement number CN110230147B). Among them, the padding process involves sending the fabric into a padding device (sometimes called a padding tank) for dyeing. However, current padding production lines can usually only pad fabric of one thickness specification. Due to the diversity of flannel products, different flannel products have different requirements for fabric thickness. Therefore, in order to adapt to the market, companies will install multiple padding production lines in their workshops, which requires a very large area of ​​production space. Therefore, current padding production lines are not suitable for most textile companies.

[0005] In addition, current impregnation production lines have poor drying effects on fabrics after impregnation, which is reflected in at least the following aspects:

[0006] First, after the fabric is impregnated, it absorbs too much slurry, which will affect the drying effect during drying, thus affecting the impregnation effect.

[0007] Secondly, during the fabric impregnation process, only a "single-pass" impregnation and drying is usually carried out. For some fabrics with a certain thickness, the effect of this "single-pass" impregnation and drying is extremely limited.

[0008] In summary, there is an urgent need to provide a new dip rolling production line (dip rolling system) to solve the above-mentioned defects. Summary of the Invention

[0009] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an impregnation system and production process for waterless flannel fabrics, aiming to solve the problems mentioned in the background technology.

[0010] The technical solution of this invention is implemented as follows: an impregnation system for waterless flannel fabric, comprising, in the impregnation sequence:

[0011] Traction components;

[0012] Impregnated components;

[0013] Drying components;

[0014] The traction assembly is capable of controlling the fabric to pass sequentially through the padding assembly and the drying assembly; characterized in that: the drying assembly has at least a drying zone and a squeezing zone, and the traction assembly has at least a first traction zone and a second traction zone;

[0015] The fabric can move between the padding assembly, the extrusion zone and the drying zone under the control of the first traction zone and / or the second traction zone;

[0016] When the fabric enters the extrusion zone from the padding assembly, the extrusion zone squeezes the fabric and squeezes out excess slurry, and then enters the drying zone for drying under the control of the first traction zone and / or the second traction zone.

[0017] By adopting the above technical solution:

[0018] The impregnation system of the present invention consists of a traction component, an impregnation component, and a drying component. Unlike existing impregnation systems, the traction component of the present invention is provided with a first traction zone and a second traction zone (each located at the end of the impregnation system to guide the movement of the fabric). The impregnation component is located between the first traction zone and the second traction zone. Through the guidance of the first traction zone and the second traction zone, the fabric can move from the first traction zone to the second traction zone and pass through the impregnation component, or the fabric can move from the second traction zone to the first traction zone and pass through the impregnation component. Thus, the fabric can be impregnated multiple times in one impregnation production line (impregnation system), thereby improving the impregnation effect.

[0019] Furthermore, in order to cooperate with the impregnation process, the present invention provides a drying zone and a pressing zone on the drying assembly. The pressing zone is used to press the impregnated fabric. On the one hand, it is used to squeeze out excess slurry, and on the other hand, it can also allow the slurry to penetrate into the fabric during the pressing process. When the fabric enters the drying zone for drying after pressing, the impregnation effect can be improved.

[0020] Preferably, the drying assembly includes:

[0021] Chassis, having a cavity;

[0022] The fabric inlet and outlet are located on the machine casing and are connected to the machine cavity;

[0023] The adjustment assembly is located inside the machine cavity and has several adjustment rollers that can move and adjust the adjacent gaps;

[0024] The fabric enters the machine cavity through the inlet and exits the machine cavity through the outlet; the adjustment assembly can integrate the squeezing zone and the drying zone within the machine cavity.

[0025] Preferably, the adjustment component includes:

[0026] Several first mounting plates are rotatably connected to the inner wall of the machine cavity via a first rotating shaft;

[0027] Several adjusting rollers are rotatably mounted on the first mounting plate;

[0028] The first transmission ring is located inside the machine cavity via the first support shaft and can be controlled to rotate by the first drive device;

[0029] Several first transmission rods are disposed between the first transmission ring and the first mounting plate, and are rotatably connected to both respectively;

[0030] The drying device is located inside the machine cavity and is capable of supplying hot air into the machine cavity;

[0031] The adjusting rollers are distributed at equal intervals around the center of the first transmission ring. When the first transmission ring is controlled to rotate by the first driving device, the first transmission rod drives the first mounting plate to rotate around the first rotating shaft as the reference point, thereby increasing or decreasing the distance between adjacent adjusting rollers.

[0032] Preferably, the drying device includes:

[0033] Several second mounting plates are rotatably connected to the inner wall of the machine cavity via a second rotating shaft;

[0034] Several drying rollers are rotatably mounted on the second mounting plate;

[0035] The second transmission ring is located inside the machine cavity via the second support shaft and can be controlled to rotate by the second drive device;

[0036] Several second transmission rods are disposed between the second transmission ring and the second mounting plate, and are rotatably connected to both respectively;

[0037] The drying rollers are equidistantly distributed around the center of the second transmission ring. When the second transmission ring is controlled to rotate by the second drive device, the second transmission rod drives the second mounting plate to rotate around the second rotating shaft as the reference point, so that the drying rollers contact or separate from the adjusting rollers.

[0038] By adopting the above technical solution:

[0039] The present invention incorporates an adjustment component in the drying assembly, which has multiple modes. In different modes, the drying assembly can be switched between a compression zone (for compressing the fabric) and a drying zone (for drying the fabric). Therefore, the number of devices is reduced to a certain extent, and the space occupied in the workshop is reduced.

[0040] The different modes of the adjustment component of this invention are not only about switching between the extrusion zone and the drying zone of the drying component, but can also be used to produce fabrics of different thicknesses. That is, by controlling the gap between the adjustment rollers, the adjustment rollers can be divided into multiple groups or a single group of adjustment rollers, which can be used to pull fabrics of different thicknesses and cooperate with the drying rollers to dry and extrude the fabrics.

[0041] Preferably, the drying roller comprises:

[0042] The outer roller body is rotatably connected to the second mounting plate and has a roller cavity, and injection ports communicating with the roller cavity are distributed on the surface of the outer roller body;

[0043] The inner roller body is composed of a left inner roller and a right inner roller formed in the roller cavity, and can slide axially relative to the outer roller body, and divides the roller cavity into an air inlet cavity, an exhaust cavity, a drainage cavity and a water inlet cavity;

[0044] The return spring consists of a left spring located in the air intake chamber and a right spring located in the water intake chamber;

[0045] The misalignment opening is formed on the left inner roller and / or the right inner roller, and is aligned or misaligned with the injection opening when the left inner roller and / or the right inner roller moves axially relative to the outer roller body.

[0046] An air inlet is located on the left inner roller, and an airflow groove is formed on the inner wall of the roller cavity, which connects the air inlet cavity and the exhaust cavity.

[0047] The water inlet is located on the right inner roller, and a water flow groove is formed on the inner wall of the roller cavity, which connects the water inlet cavity and the water outlet cavity.

[0048] The air inlet chamber and water inlet chamber can be supplied with hot air and cleaning fluid by the air supply system and the liquid supply system, respectively.

[0049] Preferably, the gas supply system includes:

[0050] Air supply pump;

[0051] The main gas supply line is connected to the output end of the gas supply pump.

[0052] A gas supply control valve having one input terminal and at least two output terminals;

[0053] At least two gas supply branches, each with one input terminal and several output terminals;

[0054] Each output end of each air supply branch is connected to the drying roller in each drying component, and the input end of each air supply branch is connected to the output end of the air supply control valve.

[0055] The liquid supply system includes:

[0056] Liquid supply pump;

[0057] The main liquid supply line is connected to the output end of the liquid supply pump;

[0058] A liquid supply control valve having one input terminal and at least two output terminals;

[0059] At least two sets of liquid supply branches, each with one output terminal and several output terminals;

[0060] Each output terminal of each liquid supply branch is connected to the drying roller in each drying component, and the input terminal of each liquid supply branch is connected to the output terminal of the liquid supply control valve.

[0061] Preferably, it further includes a control system for controlling the air supply pump and the liquid supply pump, the control system comprising at least a central control unit, a processor, a first controller and a second controller, the first controller and the second controller being used to control the air supply pump and the liquid supply pump respectively;

[0062] The first controller and the second controller are respectively able to receive the execution signal from the processor, and control the start of the air supply pump or the liquid supply pump by the first controller and the second controller respectively.

[0063] The first controller and the second controller can also be configured to be in a linkage mode. In the linkage mode, the first controller receives the execution signal from the processor and sends the same execution signal to the second controller based on the execution signal, so that the first controller and the second controller control the start of the air supply pump and the liquid supply pump by relying on the same execution signal.

[0064] By adopting the above technical solution:

[0065] The drying roller of the present invention not only dries the fabric, but also cleans the adjusting roller and the machine cavity inside the drying assembly. The control system can clean the drying assembly in different modes to achieve better cleaning results.

[0066] Furthermore, this invention also discloses a production process for waterless flannel fabric, which uses the aforementioned padding system and is characterized by comprising the following steps:

[0067] S1: The warped raw material is fed into a warp knitting machine for weaving to obtain a rough fabric;

[0068] S2: The blank from step S1 is sent into the impregnation and drying system after being de-spun.

[0069] S3: After the fabric that has been impregnated in step S2 is ironed, brushed, combed and sheared in sequence, a waterless flannel fabric is obtained.

[0070] In step S2, the slurry in the padding system is a waterless reactive dye.

[0071] Preferably, in step S2, the impregnated fabric is first mounted onto the traction assembly, and the following activities are performed under the control of the first and second traction zones of the traction assembly:

[0072] S-1: The fabric is fed into the drying zone of the drying unit by the traction component for preheating;

[0073] S-2: The fabric that has been preheated in step S-1 is fed into the padding assembly for padding, and after padding, it is fed into the extrusion zone of the drying assembly for slurry extrusion, and then wound up by the second traction zone of the traction assembly.

[0074] S-3: Under the control of the traction component, the fabric in the second traction zone of the traction component is fed into the drying zone of the drying component for drying, and after drying, it continues to enter the padding component for padding. Then, it enters the extrusion zone of the drying component again for slurry extrusion, and is then wound up by the first traction zone of the traction component.

[0075] Repeat steps S-1, S-2, and S-3 to complete the impregnation of the fabric;

[0076] The slurry discharged after being squeezed out of the extrusion zone can be returned to the padding assembly;

[0077] The extrusion zone and drying zone in steps S-1, S-2 and S-3 can be switched within the same drying assembly under the control of the first drive device and / or the second drive device, so as to perform reciprocating padding, extrusion and drying on the fabric.

[0078] Preferably, it further includes a method for cleaning the adjusting roller, which includes the following steps:

[0079] SA: Prepare the cleaning cord. According to the traction method of the fabric, pass the cord through the adjusting roller in sequence. The two ends of the cleaning cord are wound up and unwound by the fabric traction rollers of the first traction zone and the second traction zone, respectively.

[0080] SB: Through the cooperation of the fabric traction rollers in the first traction zone and the second traction zone, the rope drives the adjusting roller to rotate clockwise or counterclockwise when it is wound or unwound by the fabric traction roller.

[0081] SC: In the drip wetting mode, the regulating roller and the drying roller are controlled by the first transmission ring and the second transmission ring respectively to approach and contact each other, so that the drying roller can rotate as the regulating roller is driven to rotate by the cleaning rope. Subsequently, the liquid supply system and the air supply system are started one after another and the cleaning liquid is distributed on the surface of the regulating roller through the first diameter spray channel formed by the misalignment port and the spray port.

[0082] SD: After step SC is completed, switch to the gas-liquid strong washing mode. While the adjusting roller and the drying roller are in contact, the linkage mode between the first controller and the second controller is used to start the air supply system and the liquid supply system at the same time. The cleaning liquid and hot air are sprayed out at the same time through the second diameter spray channel formed by the misalignment port and the spray port. Each drying roller is used to perform strong washing on each adjusting roller.

[0083] SE: After step SD is completed, switch to pure water cleaning mode, supply water to the drying roller through the water supply system, and spray the cleaning liquid out from the second diameter spray channel formed by the misalignment port and the spray port. During the cleaning spraying process, the first drive ring and the second drive ring drive the adjustment roller and the drying roller to move respectively, so that the cleaning liquid sprayed from the drying roller can rinse each position of the adjustment roller, and then the cleaning is completed.

[0099] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0100] Example 1

[0101] like Figure 1-4 As shown, this invention discloses an impregnation system for waterless flannel fabric, which includes the following components in the impregnation sequence:

[0102] Traction components;

[0103] Impregnated assembly 11;

[0104] Drying component 12;

[0105] The traction assembly is capable of controlling the fabric to pass sequentially through the padding assembly 11 and the drying assembly 12; characterized in that: the drying assembly 12 has at least a drying zone 12a and a squeezing zone 12b, and the traction assembly has at least a first traction zone 10a and a second traction zone 10b.

[0106] The fabric can move between the padding assembly 11, the extrusion zone 12b and the drying zone 12a under the control of the first traction zone 10a and / or the second traction zone 10b.

[0107] When the fabric enters the extrusion zone 12b from the padding assembly 11, the extrusion zone 12b extrudes the fabric and squeezes out excess slurry, and then enters the drying zone 12a for drying under the control of the first traction zone 10a and / or the second traction zone 10b.

[0108] In this embodiment, the extrusion zone 12b and drying zone 12a of the drying assembly 12 are respectively provided with a number of sets of rollers 20.

[0109] In this embodiment, the first traction zone 10a and the second traction zone 10b are respectively fabric traction rollers 21 arranged on both sides of the impregnation assembly 11. Each first traction zone 10a and the second traction zone 10b has at least two traction rollers 21 (in this embodiment, three traction rollers 21 are taken as an example). The traction rollers 21 are supported by the support base 22.

[0110] In this embodiment, the impregnation assembly 11 is an impregnation container 110 disposed between the drying assembly 12. The impregnation container 110 is filled with slurry, and an impregnation auxiliary roller 111 is disposed on the impregnation container 110.

[0111] refer to Figure 1-3 The principle of this embodiment is:

[0112] This embodiment provides traction padding for two different specifications (thicknesses) of fabrics, as follows:

[0113] refer to Figure 1 When impregnating a thin fabric, the fabric to be impregnated is installed on each fabric traction roller in the first traction zone, and passes through the first drying assembly, the impregnation assembly, and the second drying assembly in sequence from left to right, and is then wound up by the fabric traction roller in the second traction zone. In this embodiment, during the left-to-right traction process, the fabric traction roller in the second traction zone is driven by a motor to perform the winding operation, and the fabric traction roller in the first traction zone is driven by a motor to perform the unwinding operation, thus performing the impregnation and drying of the fabric.

[0114] refer to Figure 2When impregnating thicker fabrics, the fabric to be impregnated is installed on the lower fabric traction roller in the first traction zone (because thicker fabrics are relatively heavy, a lower fabric traction roller is chosen; however, other traction roller heights can be selected if conditions permit). Other processes during traction are the same as... Figure 1 Similarly, the difference lies in its longer traction stroke (dwell time) at the padding assembly position, which allows thicker fabrics to move in the padding container for a longer time to ensure the padding effect.

[0115] According to the traction principle of this embodiment, when the fabric moves, taking the left-to-right direction as an example, the fabric is first preheated by the first drying component, then enters the padding, and after padding, it enters the extrusion zone of the second drying component for extrusion to squeeze out excess sizing material on the fabric. Then it enters the drying zone of the second drying component for drying, and is then wound up by the fabric traction roller of the second traction zone. Subsequently, the fabric is pulled from right to left by controlling the first and second traction zones.

[0116] In summary, this embodiment can perform impregnation and padding of fabrics of different specifications, and can always ensure the drying effect of the fabric (drying after extrusion, and different traction arrangements in the drying assembly according to different specifications of fabrics, so as to change the number of rollers that extrude and traction the fabric).

[0117] Example 2 differs from Example 1 in that...

[0118] like Figure 5-11 As shown, in this embodiment: the drying assembly 12 includes:

[0119] The chassis 30 has a cavity 31;

[0120] The inlet 32 ​​and outlet 33 are located on the housing 30 and are connected to the machine cavity 31;

[0121] The adjustment assembly is located inside the machine cavity 31 and has several adjustment rollers 34 that can move and adjust the adjacent gaps;

[0122] The fabric enters the machine cavity 31 through the inlet 32 ​​and exits the machine cavity 31 through the outlet 33; the adjustment component can integrate the squeezing zone and the drying zone within the machine cavity 31.

[0123] In this embodiment: the adjustment component includes:

[0124] Several first mounting plates 40 are rotatably connected to the inner wall of the machine cavity 31 via a first rotating shaft 41;

[0125] Several adjusting rollers 42 are rotatably mounted on the first mounting plate 40;

[0126] The first transmission ring 43 is disposed in the machine cavity 31 via the first support shaft 44 and can be controlled to rotate by the first drive device. The first transmission ring 43 is provided with a first limiting groove 45 for the first support shaft 44 to move.

[0127] A plurality of first transmission rods 46 are disposed between the first transmission ring 43 and the first mounting plate 40, and are rotatably connected to both of them respectively;

[0128] The drying device is located inside the machine cavity 31 and is capable of supplying hot air into the machine cavity 31;

[0129] The adjusting rollers 42 are circumferentially equidistantly distributed around the center of the first transmission ring 43. When the first transmission ring 43 is controlled to rotate by the first driving device, the first transmission rod 46 drives the first mounting plate 40 to rotate around the first rotating shaft 41 as the reference point, thereby expanding or shrinking the distance between adjacent adjusting rollers 42.

[0130] In this embodiment: the drying device includes:

[0131] Several second mounting plates 50 are rotatably connected to the inner wall of the machine cavity 31 via a second rotating shaft 51;

[0132] Several drying rollers 52 are rotatably mounted on the second mounting plate 50;

[0133] The second transmission ring 53 is disposed in the machine cavity 31 via the second support shaft 54 ​​and can be controlled to rotate by the second drive device. The second transmission ring 53 is provided with a second limiting groove 55 for the second support shaft 54 ​​to move.

[0134] Several second transmission rods 56 are disposed between the second transmission ring 53 and the second mounting plate 50, and are rotatably connected to both of them respectively;

[0135] The drying rollers 52 are equidistantly distributed around the center of the second transmission ring 53. When the second transmission ring 53 is controlled to rotate by the second driving device, the second transmission rod 56 drives the second mounting plate 50 to rotate around the second rotating shaft 51 as the reference point, so that the drying rollers 52 contact or separate from the adjusting rollers 42.

[0136] In this embodiment, a padding zone 11a is formed between the chassis 30 for placing the padding assembly 11.

[0137] In this embodiment, the drying roller 52 is hollow and a hot air outlet 520 is provided on the surface of the drying roller 52. In this embodiment, the hot air supply originates from one end of the drying roller 52, which sends hot air into the drying roller 52 and sprays it out through the hot air outlet 520 to dry the fabric in the machine cavity.

[0138] In this embodiment, the machine cavity 31 is provided with gears 61 that mesh with the first transmission ring or the second transmission ring respectively. The first driving device (not shown in the figure, generally a motor) and the second driving device (not shown in the figure, generally a motor) drive the gears to rotate clockwise or counterclockwise respectively to control the first transmission ring or the second transmission ring to rotate clockwise or counterclockwise.

[0139] In this embodiment, the adjusting roller is coaxially arranged with the first mounting plate and rotatably connected to the first mounting plate, and the drying roller is coaxially arranged with the second mounting plate and rotatably connected to the second mounting plate.

[0140] Furthermore, this embodiment also provides a production process for waterless flannel fabric, which uses the above-mentioned padding system and is characterized by including the following steps:

[0141] S1: The warped raw material is fed into a warp knitting machine for weaving to obtain a rough fabric;

[0142] S2: The blank from step S1 is sent into the impregnation and drying system after being de-spun.

[0143] S3: After the fabric that has been impregnated in step S2 is ironed, brushed, combed and sheared in sequence, a waterless flannel fabric is obtained.

[0144] In step S2, the slurry in the padding system is a waterless reactive dye.

[0145] In this embodiment: In step S2, the impregnated fabric is first mounted onto the traction assembly, and the following activities are performed under the control of the first and second traction zones of the traction assembly:

[0146] S-1: The fabric is fed into the drying zone of the drying unit by the traction component for preheating;

[0147] S-2: The fabric that has been preheated in step S-1 is fed into the padding assembly for padding, and after padding, it is fed into the extrusion zone of the drying assembly for slurry extrusion, and then wound up by the second traction zone of the traction assembly.

[0148] S-3: Under the control of the traction component, the fabric in the second traction zone of the traction component is fed into the drying zone of the drying component for drying, and after drying, it continues to enter the padding component for padding. Then, it enters the extrusion zone of the drying component again for slurry extrusion, and is then wound up by the first traction zone of the traction component.

[0149] Repeat steps S-1, S-2, and S-3 to complete the impregnation of the fabric;

[0150] The slurry discharged after being squeezed out of the extrusion zone can be returned to the padding assembly;

[0151] The extrusion zone and drying zone in steps S-1, S-2 and S-3 can be switched within the same drying assembly under the control of the first drive device and / or the second drive device, so as to perform reciprocating padding, extrusion and drying on the fabric.

[0152] refer to Figure 5-11 This embodiment provides impregnation modes for fabrics of different specifications, as detailed below:

[0153] Impregnation of thinner fabrics (reference) Figure 5-8 as well as Figure 11 ):

[0154] The fabric enters through different inlets, is drawn by two adjusting rollers, and exits from various outlets. (Reference) Figure 6 (This is a schematic diagram of the machine cavity being adjusted into a squeezing zone by the adjustment component.) In this state, the fabric is squeezed twice by two adjustment rollers. Taking this embodiment as a reference, there are a total of 6 adjustment rollers in the machine cavity, and the adjustment rollers are combined in pairs to simultaneously pull 3 fabrics and perform 2 squeezing operations on each fabric.

[0155] refer to Figure 8 (A schematic diagram of the machine cavity adjusted into the drying zone by the adjustment components). In this state, the fabric passes through the padding components and the extrusion zone, and then enters the machine cavity again through the fabric inlet. At this time, the adjustment rollers are separated from each other and close to the drying rollers. The separation of the adjustment rollers allows the fabric to have better contact with the hot air in the machine cavity when it moves, thereby ensuring the drying effect of the fabric. In addition, during the fabric traction process, the drying roller can rotate due to the movement of the adjustment rollers or the fabric (eliminating the need for a driver to drive the drying roller). During the rotation of the drying roller, the hot air outlets on the surface of the drying roller spray air, so that the hot air quickly and fully fills the machine cavity, thereby improving the drying efficiency.

[0156] Therefore, in this embodiment, by adjusting the configuration of the components, the volume of the drying components can be reduced while ensuring the traction of multiple tissues. That is, compared with Embodiment 1, this embodiment can switch within the same machine cavity by adjusting the configuration of the components. Unlike Embodiment 1, it does not require the setting of a dedicated extrusion zone and drying zone. This embodiment reduces the number of adjusting rollers, thereby reducing the volume of the drying components, while also ensuring the traction requirements.

[0157] When impregnating thicker fabrics (refer to) Figure 5 , 7 (9-11)

[0158] The fabric enters through any inlet, passes sequentially around each adjusting roller, and exits the machine cavity through any outlet. (Refer to...) Figure 9 (This is a schematic diagram of the machine cavity being adjusted into a squeezing zone by the adjustment components.) In this mode, the fabric can be squeezed 6 times continuously by each adjustment roller and then removed after squeezing.

[0159] refer to Figure 10 (This is a schematic diagram of the machine cavity being adjusted into a drying zone by the adjusting components). In this state, the fabric passes through the padding components and the squeezing zone and re-enters the machine cavity through the fabric inlet. At this time, the adjusting rollers separate from each other and the residence time of the fabric in the machine cavity is increased (to increase the drying time), and the fabric is dried by the hot air sprayed from the drying rollers.

[0160] In summary, the specific process of this embodiment can be as follows:

[0161] During padding, the first traction zone feeds the fabric into the first chamber (which can be adjusted to a drying zone) for preheating, and then into the padding assembly for padding. After padding, the fabric is fed into the second chamber (which can be adjusted to a pressing zone) for pressing, and then wound up by the second traction zone. Subsequently, the second traction zone feeds the fabric into the second chamber (which can be adjusted to a drying zone) for drying, and then it enters the padding assembly again for padding, and is fed into the first chamber (which can be adjusted to a pressing zone) for pressing, and then returns to the first traction zone for winding. The above steps are repeated to complete the padding of the fabric.

[0162] In this embodiment:

[0163] The adjustment of the adjusting roller and the drying roller is achieved by rotating the first and second transmission rings clockwise or counterclockwise, respectively, which in turn drives the first or second mounting plate to move via the first or second transmission rod, thereby changing the position of the adjusting roller or the drying roller (see reference). Figure 7 Taking the first transmission ring as an example, when the first transmission ring rotates clockwise, the second transmission ring drives the first mounting plate to rotate clockwise around the first rotating shaft, causing the distance between the adjusting rollers on the first mounting plate to change.

[0164] It is worth mentioning that:

[0165] In this embodiment, when switching from the extrusion zone to the drying zone, the adjusting roller changes from a state of separation from the drying roller to a state of contact between the adjusting roller and the drying roller. When in contact, the adjusting roller rotates while pulling the fabric, which in turn drives the drying roller to rotate. When the drying roller rotates, it causes the hot air outlet on the surface of the drying roller to deliver hot air to various positions in the machine cavity, so that the hot air quickly fills the entire machine cavity, ensuring the drying effect on the fabric. In this embodiment, after the fabric is impregnated, it is extruded to squeeze out excess sizing material (for easy drying). Alternatively, a return pipe and a return pump can be set between the bottom of the machine cavity and the impregnation container to send the sizing material back to the impregnation container. At the same time, the sizing material can also penetrate into the fabric to improve the impregnation effect.

[0171] The misalignment opening 80 is formed on the left inner roller 72 and / or the right inner roller 73 (in this embodiment, it is provided on the left inner roller 72), and is aligned or misaligned with the spray opening 71 when the left inner roller 72 and / or the right inner roller 73 moves axially relative to the outer roller body 70.

[0172] An air inlet 81 is provided on the left inner roller 72, and an airflow groove 82 is formed on the inner wall of the roller cavity, which connects the air inlet cavity 74 and the exhaust cavity 75 through the air inlet 81.

[0173] The water inlet 83 is located on the right inner roller 73, and a water flow groove 84 is formed on the inner wall of the roller cavity, which connects the water inlet cavity 77 and the drainage cavity 76 through the water inlet 83.

[0174] The air inlet chamber 74 and the water inlet chamber 77 can be supplied with hot air and cleaning fluid by the air supply system and the liquid supply system, respectively.

[0175] In this embodiment: the gas supply system includes:

[0177] The main gas supply line 91 is connected to the output end of the gas supply pump 90;

[0178] The gas supply control valve 92 has one input terminal and at least two output terminals;

[0179] At least two sets of gas supply branches 93, each with one input terminal and several output terminals;

[0180] Each output end of each group of air supply branches 93 is connected to the air inlet chamber 74 of the drying roller 52 in each drying component (machine cavity), and the input end of each group of air supply branches 93 is connected to the output end of the air supply control valve 92.

[0181] The liquid supply system includes:

[0182] Liquid supply pump 94;

[0184] The liquid supply control valve 96 has one input terminal and at least two output terminals;

[0185] At least two sets of liquid supply branches 97, each with one output terminal and several output terminals;

[0186] Each output end of each liquid supply branch 97 is connected to the water inlet chamber 77 of the drying roller 52 in each drying assembly, and the input end of each liquid supply branch 97 is connected to the output end of the liquid supply control valve 96.

[0187] In this embodiment, a control system for controlling the air supply pump 90 and the liquid supply pump 94 is also included. The control system consists of at least a central control unit 98, a processor 99, a first controller 991, and a second controller 992.

[0188] The first controller 991 and the second controller 992 can respectively receive the execution signal from the processor 99, and control the air supply pump 90 or the liquid supply pump 94 to start by relying on the first controller 991 and the second controller 992 respectively.

[0189] The first controller 991 and the second controller 992 can also be configured to a linkage mode.

[0190] refer to Figure 12-13In this embodiment, the drying roller can not only supply hot air into the machine cavity, but also clean the adjusting roller during the cleaning of the machine cavity.

[0191] In this embodiment, the air supply method for the drying roller is as follows: the air supply pump is started, and hot air is sent into the air inlet chamber from the air supply branch, so that the air pressure in the air inlet chamber is increased, and the left inner roller is moved to the right, so that the air flow groove connects the air inlet and the air inlet chamber, so that the gas in the air inlet chamber enters the exhaust chamber. At this time, the misalignment port and the injection port are overlapped and connected, so that the hot air can be sprayed from the exhaust chamber into the machine cavity through the misalignment port and the injection port.

[0192] Similarly, the liquid supply method of the drying roller in this embodiment is as follows: start the water supply pump, and the cleaning liquid enters the water inlet chamber from the liquid supply branch, which increases the water pressure in the water inlet chamber and drives the right inner roller to move to the left, so that the water chute connects the water inlet and the water inlet chamber, so that the cleaning liquid in the water inlet chamber enters the drain chamber, which increases the water pressure in the drain chamber and drives the left inner roller to move to the left, so that the misalignment port and the spray port overlap and connect, so that the cleaning liquid can be sprayed from the misalignment port and the spray port from the drain chamber (or exhaust chamber) into the machine cavity.

[0193] Based on the air and liquid supply principle of the drying roller in this embodiment, this embodiment has at least the following cleaning modes:

[0194] Pure water cleaning mode: Water is supplied to the water inlet chamber through the liquid supply system, enters the drain chamber through the water flow channel, and is sprayed out through the misalignment port and the spray nozzle when the left inner roller moves to the left.

[0195] The drip wetting mode is as follows: water is supplied to the water inlet chamber through the liquid supply system and enters the drain chamber through the water flow channel. Then the liquid supply system is closed and the air supply system is opened. Hot air is sent into the air inlet chamber through the air supply system, and the left inner roller moves to the right, so that the misalignment port and the spray port are aligned. Water flows out from the aligned part of the misalignment port and the spray port. During the outflow process, the drying rotation is accompanied, so that the water flow wets the respective adjusting rollers.

[0196] The air-liquid strong washing mode is as follows: air is supplied through the air supply system to align the misalignment port and the spray port, and then the water supply system connects the water inlet chamber and the water outlet chamber to the water flow channel. Then, hot air enters the exhaust chamber and cleaning liquid enters the drain chamber. After partial mixing or mixing, the two are sprayed out simultaneously from the spray port and the misalignment port. The airflow can increase the impact force of the water jet to clean stubborn impurities on the regulating roller.

[0197] Based on the various cleaning modes described above, this embodiment provides at least the following automatic cleaning method for the adjusting roller, which includes:

[0198] SA: Prepare the cleaning cord. According to the traction method of the fabric, pass the cord through the adjusting roller in sequence. The two ends of the cleaning cord are wound up and unwound by the fabric traction rollers of the first traction zone and the second traction zone, respectively.

[0199] SB: Through the cooperation of the fabric traction rollers in the first traction zone and the second traction zone, the rope drives the adjusting roller to rotate clockwise or counterclockwise when it is wound or unwound by the fabric traction roller.

[0200] SC: In the drip wetting mode, the regulating roller and the drying roller are controlled by the first transmission ring and the second transmission ring respectively to approach and contact each other, so that the drying roller can rotate as the regulating roller is driven to rotate by the cleaning rope. Subsequently, the liquid supply system and the air supply system are started one after another and the cleaning liquid is distributed on the surface of the regulating roller through the first diameter spray channel formed by the misalignment port and the spray port.

[0201] SD: After step SC is completed, switch to the gas-liquid strong washing mode. While the adjusting roller and the drying roller are in contact, the linkage mode between the first controller and the second controller is used to start the air supply system and the liquid supply system at the same time. The cleaning liquid and hot air are sprayed out at the same time through the second diameter spray channel formed by the misalignment port and the spray port. Each drying roller is used to perform strong washing on each adjusting roller.

[0202] SE: After step SD is completed, switch to pure water cleaning mode, supply water to the drying roller through the water supply system, and spray the cleaning liquid out from the second diameter spray channel formed by the misalignment port and the spray port. During the cleaning spraying process, the first drive ring and the second drive ring drive the adjustment roller and the drying roller to move respectively, so that the cleaning liquid sprayed from the drying roller can rinse each position of the adjustment roller, and then the cleaning is completed.

[0203] In this embodiment, the linkage mode formed between the first controller and the second controller can ensure that the water supply system and the air supply system start at the same time, and that the left inner roller and the right inner roller open the airflow groove and the water flow groove at the same time, so as to ensure the normal operation of the air-liquid strong washing mode.

[0204] It is worth mentioning that:

[0205] In this embodiment, the cleaning rope can bypass the immersion container when it passes around the immersion assembly, and can be pulled by the immersion auxiliary roller located at the top layer. When the cleaning rope moves, it can drive the adjusting roller to rotate.

[0206] In addition, a drain valve is usually installed at the bottom of the machine cavity to discharge the cleaning wastewater.

[0207] In this embodiment, the diameter of the first-caliber injection channel is smaller than the diameter of the second-caliber injection channel.

[0208] In summary, through the various embodiments of the present invention, it can be seen that the present invention has at least the following beneficial effects:

[0209] 1) Referring to Examples 1-3, the present invention can impregnate fabrics of different specifications (thicknesses), and the impregnation of the present invention can achieve multiple reciprocating motions. Compared with the existing "single-stroke" impregnation method, it can ensure the impregnation effect, especially when impregnating thicker fabrics.

[0210] 2) Referring to Examples 1-3, the present invention can dry or preheat the fabric before impregnation and squeeze the fabric after impregnation to improve the impregnation effect of the fabric.

[0211] 3) Referring to Examples 2-3, the present invention reduces the number of "squeezing rollers" in the drying assembly. A small number of adjusting rollers can switch between the form (squeezing zone and drying zone) in the drying assembly, and ensure / or improve the squeezing effect and drying effect to improve the impregnation effect of the fabric. At the same time, the volume of the drying assembly is reduced (previously, two independent squeezing chambers and drying chambers were required, and the number of "squeezing rollers" was relatively large).

[0212] 4) Referring to Examples 2-3, in order to increase the drying efficiency of fabrics, the present invention makes contact between the adjusting roller and the drying roller during drying, so that the drying roller can be driven to rotate by the moving fabric or the rotating adjusting roller, and cooperates with the air jet of the drying roller to make the hot air quickly fill the entire machine cavity, thereby improving the drying efficiency. Furthermore, by driving the drying roller to rotate through the adjusting roller, the number of drivers controlling the rotation of the drying roller is reduced, thus achieving the purpose of energy saving.

[0213] 5) Referring to Embodiment 3, in order to facilitate cleaning (or achieve automatic cleaning), the present invention provides an air supply system (mainly for supplying hot air for drying) and a liquid supply system (for cleaning the adjusting roller and the machine cavity) in combination, and relies on the drying roller to achieve the purpose of automatically cleaning the adjusting roller, thereby improving the cleaning efficiency.

[0214] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
