Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, specifically to a continuous finishing system and process for soft composite protective fabrics. Background Technology

[0002] To enhance the functionality and comfort of fabrics during use, finishing processes are often employed to improve their appearance and feel, improve performance, or impart special functions. Fabrics need to be immersed in a finishing bath for an extended period to allow the finishing solution to penetrate the yarns, making the immersion finishing process more demanding.

[0003] Chinese patent CN113862927A discloses a finishing device for decorative fabrics, which includes a matching finishing roller. The finishing roller has an elastic component inside, and a squeezing mechanism is installed on the elastic component. The elastic component is driven to reciprocate radially by the flow of finishing liquid inside the finishing roller, thereby squeezing the finishing liquid from the inside out and promoting the impregnation effect.

[0004] The existing devices only have a soaking function, which is limited in functionality. Furthermore, as shown in the aforementioned patent, the vibration and compression process may cause wrinkles to form on the fabric, affecting its quality and requiring further processing steps. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a continuous finishing system and process for soft composite protective fabrics, thus solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous finishing system for soft composite protective fabric, comprising a soaking tank and a lid on top of it, with a drain valve on one side of the bottom of the soaking tank. The soaking tank contains multiple upper and lower guide rollers that guide the soft composite protective fabric in an S-shaped winding motion. The bottom of the lid has a hanging structure for suspending the lower guide rollers. A magnetic roller is also rotatably mounted on the bottom inner side of the soaking tank, interfering with the soft composite protective fabric and the lower guide roller. This magnetic roller can magnetically attract the lower guide roller to increase pressure and accelerate the absorption of finishing liquid by the soft composite protective fabric. A metal pressure plate is provided on the right side of the bottom of the lid to elastically press the rightmost upper guide roller. A heating assembly is provided on the outside of the soaking tank to fill the upper guide roller with hot air for heating. The heated upper guide roller, in conjunction with the metal pressure plate, achieves ironing. A collection assembly for collecting lint and impurities from the liquid surface is located at the front of the soaking tank.

[0007] Preferably, the upper guide roller is hollow, and the heating assembly includes an electric heating air box fixedly connected to the rear side of the soaking tank. The air inlet and outlet of the electric heating air box are connected to the rear ends of two upper guide rollers located on both sides through a return air pipe and an outlet air pipe, respectively. One end of two adjacent upper guide rollers is connected through a guide air pipe to allow hot air to flow in an S-direction within the multiple upper guide rollers.

[0008] Preferably, the rear ends of the multiple upper guide rollers are all fixedly connected to driven pulleys, the bottom of the rear side of the soaking tank is fixedly connected to a motor housing, the output end of the motor in the motor housing is fixedly connected to a driving pulley, and the driving pulley and the driven pulley are connected by a belt drive. The front and rear sides of the soaking tank are both fixedly connected to protective covers that cover the driven pulleys and the rear ends of the upper guide rollers.

[0009] Preferably, a guide wheel is rotatably connected to the rear side of the soaking tank and between the driven pulleys, and the guide wheel guides the belt so that the wrap angle between the belt and the multiple driven pulleys is not less than 120°.

[0010] Preferably, the impurity collection assembly includes a collection box fixedly connected to the middle of the front side of the soaking tank, the top of the collection box is covered with a top cover, the bottom of the top cover is fixedly connected to a filter basket, and the rear side of the collection box and the portion above the upper rear edge of the filter basket is in communication with the soaking tank.

[0011] Preferably, a liquid pump is fixedly connected to the front side of the soaking tank and below the collection tank, a liquid pumping pipe is connected between the bottom of the collection tank and the liquid pump inlet, and a liquid draining pipe is connected between the liquid pump outlet and the soaking tank.

[0012] Preferably, the top of the front and rear walls of the soaking tank are provided with positioning grooves, and the bottom of the tank cover is provided with protrusions corresponding to the positioning grooves on both the front and rear sides. The top of the tank cover is provided with handles on both sides, and the tank cover and the lower guide roller can be lifted by lifting the handles or hanging handles.

[0013] Preferably, the hanging structure includes hooks disposed on the front and rear sides of the bottom of the box cover, and also includes lifting rings rotatably sleeved on the outside of both ends of the lower guide roller, and a lifting rope is connected between the hooks and the lifting rings.

[0014] This invention also discloses a continuous finishing process for soft composite protective fabrics, specifically including the following steps:

[0015] Step 1: Lift the lid and lower guide roller, then wrap the fabric around the upper and lower guide rollers in an S-shape, and then lower the lid and lower guide roller so that the lid covers the soaking tank and the lower guide roller presses the fabric onto the surface of the magnetic roller.

[0016] Step 2: Power on the equipment, start the heating component to fill the upper guide roller with hot air for heating, and then drive the upper guide roller to rotate, while simultaneously pulling the fabric to the next workstation;

[0017] Step 3: During the fabric pulling process, the fabric is immersed in the finishing solution. The lower guide roller squeezes the fabric to promote its faster absorption of the finishing solution. At the same time, the heated upper guide roller, together with the metal pressure plate, irons the pulled-out fabric.

[0018] Step 4: During the operation, the impurity collection component draws the finishing liquid from the soaking tank for circulation, so that the finishing liquid on the surface flows into the impurity collection component and filters and collects the lint.

[0019] Preferably, the liquid level of the finishing liquid is monitored in real time, and the finishing liquid is replenished in a timely manner to keep the liquid level of the finishing liquid above the lower edge of the inlet of the impurity collection component.

[0020] Beneficial effects

[0021] This invention provides a continuous finishing system and process for soft composite protective fabrics. Compared with existing technologies, it has the following advantages:

[0022] 1. The continuous finishing system and process for this soft composite protective fabric can soak the fabric in an immersion tank, which can also wash away the lint attached to the surface. With the help of the impurity collection component, the lint can be collected and processed in a centralized manner. The use of the upper and lower guide rollers can extend the soaking time of the fabric. At the same time, the magnetic attraction between the lower guide roller and the magnetic roller can press the fabric, thereby promoting the absorption of the finishing liquid. Combined with the heating component and the metal pressure plate, the fabric can also be ironed. The multiple finishing processes of the soft composite protective fabric are integrated into one, which is convenient to use and reduces the equipment footprint and cost.

[0023] 2. The continuous finishing system and process of this soft composite protective fabric, by setting a heating component to fill the upper guide roller with hot air, can heat the fabric and realize the heating and ironing of the fabric. The fabric can be ironed flat even after being soaked and wet, which improves the product quality. In addition, the hot air can be circulated for heating and reuse, reducing heat loss.

[0024] 3. The continuous finishing system and process of this soft composite protective fabric, by setting up an impurity collection component, can extract the finishing liquid from the surface of the soaking tank, and use a filter basket to filter and collect lint. The filtered finishing liquid is then discharged back into the soaking tank to form a cycle, which can promote the flow of the finishing liquid and collect the lint on the fabric. This can prevent the lint from adhering again after the fabric leaves the liquid surface, thus ensuring the cleanliness of the fabric.

[0025] 4. The continuous finishing system and process of this soft composite protective fabric, by setting up a hanging structure to connect the box cover and the lower guide roller, can simultaneously lift the lower guide roller when the box cover is opened, and can also lower the lower guide roller when the box cover is closed, which is convenient to use.

The outside of the soaking tank 1 is provided with a heating component 8 that fills the upper guide roller 3 with hot air for heating, and the upper guide roller 3 is heated and works with the metal pressure plate 7 to achieve ironing. The front side of the soaking tank 1 is provided with a collection component 9 for collecting lint and impurities on the liquid surface.

[0036] Driven pulleys 12 are fixedly connected to the rear ends of multiple upper guide rollers 3. A motor housing 13 is fixedly connected to the bottom of the rear side of the soaking tank 1. A drive pulley is fixedly connected to the output end of the motor in the motor housing 13. The drive pulley and the driven pulleys 12 are connected by a belt 14. Protective covers 15 covering the driven pulleys 12 and the rear ends of the upper guide rollers 3 are fixedly connected to the front and rear sides of the soaking tank 1. A guide wheel 16 is rotatably connected to the rear side of the soaking tank 1 and between the driven pulleys 12. The guide wheel 16 guides the belt 14 so that the wrap angle between the belt and the multiple driven pulleys 12 is not less than 120°.

[0037] The fabric can be soaked in the soaking tank 1, which can also wash away the lint attached to the surface. The impurity collection component 9 can also collect and process the shed lint. The upper guide roller 3 and the lower guide roller 4 can be used to extend the soaking time of the fabric. At the same time, the magnetic attraction between the lower guide roller 4 and the magnetic roller 6 can press the fabric, thereby promoting the absorption of the finishing liquid. Combined with the heating component 8 and the metal pressure plate 7, the fabric can also be ironed. The multiple finishing processes of soft composite protective fabrics are integrated into one, which is convenient to use and reduces the equipment's footprint and cost.

[0038] Figures 1-2 The second embodiment is shown. The main difference from the first embodiment is that the upper guide roller 3 is hollow. The heating assembly 8 includes an electric heating air box 81 fixedly connected to the rear side of the soaking tank 1. The air inlet and outlet of the electric heating air box 81 are connected to the rear ends of the two upper guide rollers 3 located on both sides through the air return pipe 82 and the air outlet pipe 83, respectively. One end of two adjacent upper guide rollers 3 is connected through the air guide pipe 84 so that hot air flows in the S direction within the multiple upper guide rollers 3.

[0039] By introducing hot air into the upper guide roller 3 through the heating component 8, the fabric can be heated and ironed. This allows the fabric to be ironed flat even after being soaked in water, improving product quality. Furthermore, the hot air can be circulated for heating, reducing heat loss.

[0040] Figure 5 The third embodiment is shown, and the main difference from the second embodiment is that: the impurity collection assembly 9 includes a collection box 91 fixedly connected to the middle of the front side of the soaking tank 1, the top of the collection box 91 is covered with a top cover 92, the bottom of the top cover 92 is fixedly connected to a filter basket 93, the rear side of the collection box 91 and the part above the rear upper edge of the filter basket 93 is connected to the soaking tank 1, the front side of the soaking tank 1 and the bottom of the collection box 91 is fixedly connected to a liquid pump 94, the bottom of the collection box 91 is connected to the liquid inlet of the liquid pump 94 through a liquid suction pipe 95, and the outlet of the liquid pump 94 is connected to the soaking tank 1 through a drain pipe 96.

[0041] By setting up the impurity collection component 9, the finishing liquid on the surface of the soaking tank 1 can be extracted, and the lint can be collected by filtering with the filter basket 93. The filtered finishing liquid is then discharged back into the soaking tank 1 to form a cycle, which can promote the flow of the finishing liquid. After collecting the lint on the fabric, it can prevent the lint from adhering again after the fabric leaves the liquid surface, thus ensuring the cleanliness of the fabric.

[0042] Figure 6 The fourth embodiment is shown. The main difference between the fourth and third embodiments is that the hanging structure 5 includes hooks 51 located on the front and rear sides of the bottom of the box cover 2, and also includes hanging rings 52 rotatably sleeved on the outside of both ends of the lower guide roller 4, and a hanging rope 53 is connected between the hooks 51 and the hanging rings 52.

[0043] By setting up a hanging structure 5 to connect the box cover 2 and the lower guide roller 4, the lower guide roller 4 can be lifted simultaneously when the box cover 2 is opened, and the lower guide roller 4 can be lowered when the box cover 2 is closed, which is convenient to use.

[0044] This invention also discloses a continuous finishing process for soft composite protective fabrics, specifically including the following steps:

[0045] Step 1: Lift the lid 2 and simultaneously lift the lower guide roller 4 using the hanging structure 5. Then, wrap the fabric around the upper guide roller 3 and the lower guide roller 4 in an S-shape. Then lower the lid 2 and the lower guide roller 4 so that the lid 2 covers the soaking tank 1 and the lower guide roller 4 presses the fabric onto the surface of the magnetic roller 6.

[0046] Step 2: Power on the equipment and start the electric heating air box 81 to fill the upper guide roller 3 with hot air through the air outlet pipe 83 for heating. After the hot air flows through multiple upper guide rollers 3 in sequence, it returns to the electric heating air box 81 through the return air pipe 82 for reheating and circulation. Then start the motor in the motor box 13, which drives the upper guide roller 3 to rotate through the pulley and belt, and at the same time pulls the fabric to the next station.

[0047] Step 3: During the fabric pulling process, the fabric is soaked in the finishing solution. The lower guide roller 4 squeezes the fabric to promote its faster absorption of the finishing solution. At the same time, the heated upper guide roller 3, together with the metal pressure plate 7, irons the pulled-out fabric.

[0048] Step 4: During the operation, the liquid pump 94 of the impurity collection component 9 works, drawing the finishing liquid in the collection tank 91 through the liquid extraction pipe 95, and indirectly drawing the upper layer finishing liquid in the soaking tank 1. After filtering and collecting the lint through the filter basket 93, it is discharged back into the soaking tank 1 for circulation.
