Description

Technical Field

[0001] The present invention belongs to the technical field of cotton fabric wrinkle removal, and specifically relates to a cotton fabric wrinkle removal mechanism and dyeing and finishing equipment for the dyeing and finishing process. Background Art

[0002] The wrinkle removal mechanism is an important part of the dyeing and finishing equipment. After the cotton fabric is unrolled, wrinkles may occur due to its stacking and winding postures. These wrinkles need to be smoothed out by the pre-treatment wrinkle removal mechanism before entering the dyeing and finishing process.

[0003] Microscopically, the appearance of wrinkles in cotton fabrics is mainly due to the breakage of hydrogen bonds in the fibers, which are detached from their original positions and bonded elsewhere. The principle of wrinkle removal is to break the hydrogen bonds in the wrinkled fibers again under certain conditions to reconnect them to the correct places. The commonly used industrial method is high-temperature steam for wrinkle removal. Steam above 100°C can temporarily relax the molecular structure, making the fiber structure easy to be readjusted to its original state. The existing high-temperature steam adjustment usually softens the cotton fabric through a steam generator and then smooths and integrates it. Considering the time difference between the two processes, the fibers may be exposed to high temperature for too long, which may cause the fibers to expand excessively and damage their own structure.

[0004] Therefore, the present application proposes a cotton fabric wrinkle removal mechanism and dyeing and finishing equipment for the dyeing and finishing process. Summary of the Invention

[0005] To solve the problems raised in the above background art, the present invention provides a cotton fabric wrinkle removal mechanism and dyeing and finishing equipment for the dyeing and finishing process.

[0015] The steam generating module further comprises an open-loop inner liner tube sleeved in the cylindrical cavity of the steam supply inner liner tube, a water pipe is further installed in the open-loop inner liner tube, the steam supply inner liner tube and the open-loop inner liner tube are both provided with opposite through holes, and the inner cavity of the water pipe and the arc cavity are connected through a connecting pipe;

[0016] A heating plate is arranged in the arc-shaped cavity and is located below the through hole to evaporate water dripping thereon.

[0017] Preferably, a through groove is provided on the open-loop inner liner pipe to form an open-loop structure, and the water pipe is used to be placed through the through groove of the open-loop inner liner pipe and installed in the open-loop inner liner pipe.

[0018] Preferably, a support table is provided on top of the open-loop liner tube, a heat-conducting slider is installed on the support table, a heating plate 2 is provided in the interlayer between the support table and the heat-conducting slider, and the heat-conducting slider is slidably connected to the inner wall of the roller shell.

[0019] Preferably, the heat-conducting sliding block is supported by heat-conducting graphite, and a notch is provided on the heat-conducting sliding block for staggering the spray holes on the outer shell of the roller body.

[0020] Preferably, an air outlet valve is further provided in the spray hole on the outer shell of the roller body, and the air outlet valve comprises a step and a valve core fixed in the inner wall of the spray hole. A valve plate is also movably provided in the spray hole, and the valve plate is elastically supported and sleeved on the valve core by an elastic member to cut off the communication between the inner cavity of the leveling roller and the external environment.

[0021] An electromagnetic attraction module is arranged on the outer periphery of the steam supply inner liner pipe and is aligned with the air outlet valve to attract the valve plate to open the spray hole.

[0022] Preferably, the area between two adjacent columns and two adjacent rows of nozzles is a wrinkle removal unit, and each wrinkle removal unit corresponds to a rectangular area on the cotton fabric, and the area, length and width of the rectangular area are correspondingly attached to the wrinkle removal unit;

[0023] The electromagnetic attraction module can control the air outlet valves corresponding to the four corners of one or two wrinkle removal units to conduct;

[0024] The recognition camera is used to recognize the area of the wrinkle removal unit corresponding to the wrinkles on the cotton fabric, and then drive the electromagnetic attraction module of the corresponding unit through the control unit.

[0025] Longitudinal grooves are formed on the support plate of the parallelogram lifting mechanism for installing the bottom roller.

[0026] A cotton fabric dyeing and finishing equipment for the dyeing and finishing process, and the dyeing and finishing equipment includes the above-mentioned cotton fabric wrinkle removal mechanism.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] In the present invention, the cotton fabric is rolled and pressed in the middle by the cooperation of the bottom roller and the leveling roller for conveying. During this process, water flows into the inside of the roller body housing through the water pipe, and is discharged into the arc-shaped cavity below the steam supply inner lining pipe through the connecting pipe. A heating sheet 1 is arranged in this cavity to immediately evaporate the water droplets dripping thereon and diffuse into the arc-shaped cavity. The arc-shaped cavity is communicated with the cavity of the roller body housing through the communication hole grooves formed on the steam supply inner lining pipe, so that the water vapor therein can be transmitted into the roller body housing. And finally, it is discharged through the spray holes formed on the roller body housing. The hot steam flow ejected from the spray holes performs heat treatment on the surface of the cotton fabric, changes the fiber structure, and makes it return to a flat state again during the rolling process.

[0029] After being heated by the heating sheet 2, the heat can be conducted to the roller body housing through the heat conduction slider arranged on it, and the internal environment temperature of the roller body housing can be increased. A layer of alumina ceramic can also be padded between the heating sheet 2 and the heat conduction slider for insulation

[0030] By recognizing the unit area corresponding to the wrinkles on the cotton fabric through the recognition camera and controlling the air outlet valves corresponding to the corresponding unit areas to conduct, targeted steam treatment can be performed on the wrinkled areas of the cotton fabric. The traditional press roller steam injection covers the entire width. Especially when steam treating the cotton fabric on a wide-width plane, this method will waste at least 70% of the steam. And this kind of whole-region high-temperature method will cause the fibers to expand excessively and the yarn strength to be lost. The present application accurately locates this week's part for precise treatment. On the one hand, it reduces the steam loss and saves energy resources. On the other hand, it reduces the damage to the fibers themselves and prolongs the service life. Description of the Drawings

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1 to 10 shown, the present invention provides a cotton fabric wrinkle removal mechanism and a dyeing and finishing equipment for the dyeing and finishing process, including a mounting frame 100. The wrinkle removal mechanism further includes:

[0044] A parallelogram lifting mechanism 200, which is arranged below the mounting frame 100;

[0045] The bottom roller 300 is installed on the parallelogram lifting mechanism 200 and moves up and down therewith;

[0046] The leveling roller 400 is installed inside the mounting frame 100 and cooperates with the bottom roller 300 to remove wrinkles from the cotton fabric;

[0047] The recognition camera 500 is installed at the front end of the wrinkle-removing mechanism to observe the state of the cotton fabric;

[0048] A number of leveling rollers 400 are provided. They are mounted on the mounting frame 100 through brackets 409. Communication pipelines 4091 are provided on the brackets 409 at both ends of the leveling roller 400 for passing water and cables respectively;

[0049] The leveling roller 400 further includes a steam generation module and a heating module arranged therein and cooperating with the communication pipeline 4091. Spray holes are evenly formed in the leveling roller 400 for spraying steam therein onto the cotton fabric.

[0050] The bottom roller 300 and the leveling roller 400 cooperate to roll the cotton fabric in the middle for conveying. During this process, the hot steam flow ejected from the spray holes performs heat treatment on the surface of the cotton fabric, changes the fiber structure, and makes it return to a flat state again during the rolling process.

[0051] The recognition camera 500 arranged thereon is used to observe the state, posture, wrinkle condition, etc. of the cotton fabric.

[0052] The bottom roller 300 is arranged on the parallelogram lifting mechanism 200, and the lifting of the bottom roller 300 is controlled by the parallelogram lifting mechanism 200.

[0053] As Figure 4 shown, the leveling roller 400 includes a roller body shell 401 with a rotating shaft installed on the bracket 409, and the bracket 409 is fixedly installed on the mounting frame 100.

[0054] The bracket 409 is composed of two units and is installed on the mounting frame 100. The middle is open and communicates with the inner cavity of the leveling roller 400. Both sides of the leveling roller 400 are installed through the bracket 409 for water and circuit respectively.

[0055] As Figure 4 shown, the steam generation module is a steam supply inner lining pipe 402 fixedly connected to the bracket 409. A cylindrical cavity and an arc cavity coaxial with the roller body shell 401 are formed in the steam supply inner lining pipe 402, and the arc cavity communicates with the inner cavity of the roller body shell 401;

[0056] The steam generation module further includes an open-loop inner liner 403 sleeved in the cylindrical cavity of the steam supply inner liner 402. A water pipe 404 is also installed in the open-loop inner liner 403. Opposite through holes are provided on both the steam supply inner liner 402 and the open-loop inner liner 403, and the inner cavity of the water pipe 404 and the arc-shaped cavity are communicated through a connecting pipe.

[0057] A first heating sheet 4022 is arranged in the arc-shaped cavity below the through hole for evaporating the water dripping thereon.

[0058] Water flows into the inside of the roller housing 401 through the water pipe 404 and is discharged into the arc-shaped cavity below the steam supply inner liner 402 through the connecting pipe. A first heating sheet 4022 is arranged in this cavity for instantaneously evaporating the water dripping thereon and diffusing it into the arc-shaped cavity. The arc-shaped cavity and the cavity of the roller housing 401 are communicated through a communication hole groove provided on the steam supply inner liner 402, so that the water vapor therein can be transmitted into the roller housing 401 and finally discharged through the spray holes provided on the roller housing 401.

[0059] The size of the water droplets dripping on the first heating sheet 4022 can be set by adjusting the size of the through hole above the arc-shaped cavity. And the water can be discharged uniformly through the water pipe 404.

[0060] As Figure 4 shown, a through groove is provided on the open-loop inner liner 403 to form an open-loop structure. The water pipe 404 is used to be placed and installed in the open-loop inner liner 403 from the through groove of the open-loop inner liner 403.

[0061] This groove is used to facilitate the assembly between the steam supply inner liner 402 and the open-loop inner liner 403. By directly shrinking and pressing the open-loop inner liner 403 into the steam supply inner liner 402 and then releasing it, the outer circumference of the open-loop inner liner 403 is fitted to the inner wall of the steam supply inner liner 402 to achieve fastening, and the through holes on the steam supply inner liner 402 and the open-loop inner liner 403 are aligned vertically.

[0062] The water pipe 404 can be directly installed into the open-loop inner liner 403 through a strip-shaped groove provided on the open-loop inner liner 403 to achieve pipe-hole plug-in connection. The open-loop inner liner 403 can be made of transparent polyethylene material, which is convenient for observing the internal pipe-hole docking condition during installation.

[0063] As Figure 4 shown, a support table 405 is further provided on the open-loop inner liner 403. A heat-conducting slider 406 is covered and installed on the support table 405. A second heating sheet 407 is arranged in the interlayer between the support table 405 and the heat-conducting slider 406. The heat-conducting slider 406 is in sliding fit connection with the inner wall of the roller housing 401.

[0064] The second heating sheet 407 extends along the axial direction. After heating, the heat can be conducted to the roller housing 401 through the heat-conducting slider 406 provided thereon, and can increase the internal environment temperature of the roller housing 401. A layer of alumina ceramic can also be interposed between the second heating sheet 407 and the heat-conducting slider 406 for insulation.

[0065] As Figure 4 and Figure 7 shown, the heat-conducting slider 406 is supported by heat-conducting graphite, and a notch 4061 is also provided on the heat-conducting slider 406 for staggering the spray holes on the roller housing 401.

[0066] Graphite has excellent heat-conducting performance and wear-resistant performance, can achieve good contact with the inner wall of the roller housing 401, and after sufficient fitting contact, the relative slip between the two is relatively smooth. At the same time, it can also transfer the heat on it to the roller housing 401. A notch 4061 is also provided on the heat-conducting slider 406 for avoiding the spray holes to prevent scratching of the heat-conducting slider 406 at the spray ports.

[0067] Figure 5 As shown, an air outlet valve 408 is also provided in the spray holes on the roller housing 401. The air outlet valve 408 includes a step 4081 fixedly installed on the inner wall of the spray hole and a valve core 4084. A valve plate 4083 is also movably provided in the spray hole. The valve plate 4083 is elastically supported by an elastic member 4082 and sleeved on the valve core 4084 to cut off the communication between the inner cavity of the flattening roller 400 and the external environment;

[0068] An electromagnetic attraction module 4021 is provided on the outer periphery of the steam supply inner liner 402 and aligned with the air outlet valve 408 for attracting the valve plate 4083 upward to conduct the spray hole.

[0069] By providing the air outlet valve 408, in the initial state, the valve plate 4083 is pushed radially outward by the elastic member 4082 to close it with the valve core 4084, making the upper spray port in a normally closed state. When the spray port rotates to be in contact with the cotton fabric, it is opened to spray steam upward for wrinkle removal work.

[0070] The opening of the spray port is achieved by the electromagnetic attraction module 4021 attracting the valve plate 4083 to move upward, compressing the elastic member 4082 to conduct the spray port, and guiding the steam in the roller housing 401 to the cotton fabric.

[0071] As Figure 9 and 10 shown, the area between adjacent two columns and adjacent two rows of spray holes is a wrinkle removal unit. Each wrinkle removal unit corresponds to a rectangular area on the cotton fabric, and the area and length and width of the rectangular area are correspondingly fitted to the wrinkle removal unit;

[0072] The electromagnetic attraction module 4021 can control the air outlet valves 408 corresponding to the four corners of one or two wrinkle removal units to conduct;

[0073] The recognition camera 500 is used to recognize the area of the wrinkle removal unit corresponding to the wrinkles on the cotton fabric, and then drives the electromagnetic attraction module 4021 of the corresponding unit through the control unit.

[0074] The preferred embodiment of the present application is to recognize the unit area corresponding to the wrinkles on the cotton fabric through the recognition camera 500, and by controlling the air outlet valve 408 of the corresponding unit area to conduct, it is possible to perform targeted steam treatment on the wrinkled area of the cotton fabric.

[0075] For example Figure 10 As shown, in the embodiment given in the present application, a total of ten air outlet valves 408 are provided around the roller housing 401. That is, the wrinkle removal area that can be processed in one week is divided into 10 unit widths, namely A1 - A10. Every time it turns one circle, the unit width on the cotton fabric is re - delimited, making its head and tail connected so as not to be disordered.

[0076] In the length direction of the wrinkle removal area, the wrinkle removal area is also divided into 15 unit lengths, namely B1 - B15, by the spacing of each spray hole along the axial direction. Thus, in cooperation with the unit width, the wrinkle stripes can be cut and classified into each wrinkle removal unit.

[0077] Through the recognition camera 500, recognize the attribution of the cut wrinkle stripes in the wrinkle removal unit. For example Figure 7 in, (A7A8, B11); (A7A8, B10); (A7A8, B9); (A7A8, B8); (A7, B7); (A6A7,B6); (A6A7, B5); (A6A7, B4); (A6, B3); (A6, B2); (A6, B1).

[0078] Thus, it can be controlled that after the wrinkle removal area of the cotton fabric in this range starts to be wound around the outer circumference of the roller housing 401, the electromagnetic attraction module 4021 controls the air outlet valves 408 in each wrinkle removal unit to open in an orderly manner. Since the magnetic field range of the electromagnetic attraction module 4021 faces downward, it can be set that when the air outlet valve 408 of the corresponding wrinkle removal unit enters the magnetic field influence range of the electromagnetic attraction module 4021, the electromagnetic attraction module 4021 is directly powered on.

[0079] Thus, control the corresponding nozzle to open for targeted wrinkle removal.

[0080] The working principle and usage process of the present invention:

[0081] In the present invention, the cotton fabric is rolled and conveyed in the middle through the cooperation of the bottom roller 300 and the leveling roller 400. During this process, water flows into the interior of the roller housing 401 through the water pipe 404 and is discharged into the arc-shaped cavity below the steam supply inner lining pipe 402 through the connecting pipe. A heating sheet 4022 is provided in this cavity to immediately evaporate the water droplets falling thereon and diffuse them into the arc-shaped cavity. The arc-shaped cavity is communicated with the cavity of the roller housing 401 through the communication hole grooves opened on the steam supply inner lining pipe 402, and the water vapor therein can be transmitted into the roller housing 401. Finally, the hot steam flow ejected from the spray holes opened on the roller housing 401 is used to perform heat treatment on the surface of the cotton fabric, change the fiber structure, and restore it to a flat state again during the rolling process.

[0082] By identifying the unit area corresponding to the wrinkles on the cotton fabric through the identification camera 500 and controlling the air outlet valve 408 corresponding to the unit area to conduct, targeted steam treatment can be performed on the wrinkled area of the cotton fabric. This is used to replace the traditional method of steam spraying by the pressure roller covering the entire width.

[0083] The identification camera 500 can capture the wrinkled area on the cotton fabric in real time, accurately identify the depth, length, and position of the wrinkles in the image, and thereby confirm how many wrinkle removal units the wrinkles penetrate into and which ones. Finally, it is used to adjust the opening and closing of the corresponding spray holes on the leveling roller 400 to perform steam spraying on the wrinkles in each unit.

[0084] For the wrinkles located in one unit, at least four spray holes around the unit where the wrinkles are located need to be opened, and the air outlet valve 408 is opened to enclose the wrinkles therein. For the wrinkles located in multiple units, the spray holes of the multiple units where the wrinkles are located need to be opened, and the air outlet valve 408 is opened to enclose the wrinkles in the multiple units therein.

[0085] In addition, a heating element for heating the roller housing 401 is also provided in the leveling roller 400. A heating sheet 407 is provided to extend along the axial direction. After heating, the heat can be conducted to the roller housing 401 through the heat-conducting slider 406 provided thereon, and the internal environment temperature of the roller housing 401 can be increased. A layer of alumina ceramic can be interposed between the heating sheet 407 and the heat-conducting slider 406 for insulation. The alumina ceramic used for insulation here is not only provided between the heat-conducting slider 406 and the heating sheet 407, but also the heating sheet 407 can be directly spliced into it, and the heating sheet can be directly wrapped inside. The upper surface of the heating sheet 407 is in contact with the alumina ceramic, and its lower surface is suspended. Its heat conduction direction is single upward (not shown in the figure).

[0086] Here, the heat-conducting slider 406 can be a graphite slider. Graphite has excellent heat-conducting and wear-resistant properties, enabling good contact with the inner wall of the roller body housing 401. After sufficient fitting contact, the relative sliding between the two is relatively smooth, and at the same time, the heat on it can be transferred to the roller body housing 401. A notch 4061 is also provided on the heat-conducting slider 406 to avoid the spray holes and prevent damage to the heat-conducting slider 406 at the spray holes.

[0087] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0088] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
