DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] This embodiment proposes an environmentally friendly printing and dyeing process for continuous printing and dyeing, which mainly includes the following steps: S1: Fabric preparation, prepare the fabric to be processed, including fabric inspection, fabric turning (in batches) and sewing steps to ensure that the quality of the fabric meets the quality requirements of subsequent processing procedures; S2: Pre-dyeing treatment, which includes singeing, desizing, scouring and bleaching, to remove impurities, grease and dirt from the fabric to ensure uniform penetration and adhesion of the dye, thereby improving the dyeing quality and color stability; S3: dyeing, by rotating the unwinding roller 11, the winding roller 12, and the plurality of tensioning rollers 13, the fabric enters the dye pool, so that the fabric can continuously contact the dye in the dye pool under the cooperation of the unwinding roller 11, the winding roller 12, and the plurality of tensioning rollers 13, ensuring that the dye in the dye pool can be continuously attached to the fabric, completing the work of attaching the dye to the fabric; S4: dewatering. Before the fabric is rolled up by the winding roller 12, the dewatering structure 2 squeezes the fabric on the fabric winding path to remove excess water (dye) on the fabric, so as to avoid excessive moisture content in the fabric, which may cause dye splashing in the subsequent processing steps, affecting the sanitary environment of the workshop and wasting dye. S5: Inspection, to check whether the fabric meets the production standard, so as to determine whether the fabric can enter the subsequent processing steps. Specifically, the fabric that meets the production standard (dyeing effect meets the standard) is sent by the staff to the next processing step (including but not limited to packaging, storage and other steps) for processing, while the fabric that does not meet the production standard (dyeing effect does not meet the standard) is sent by the staff to the unwinding roller 11 for re-dyeing until it meets the production standard.

[0021] like Figure 1~Figure 2 , Fig.11 As shown, for the third and fourth steps above, this embodiment proposes a printing and dyeing machine body 1, which has a dye pool, a reel 11, a reel 12, and a plurality of tensioning rollers 13; the reel 11, the reel 12, and the plurality of tensioning rollers 13 are all rotatably connected to the machine body 1 and are located on the dye pool. Preferably, the reel 12 should be provided with a control component such as a rotating motor for driving the reel 12 to rotate, so as to ensure that the reel 11, the reel 12, and the plurality of tensioning rollers 13 cooperate with each other, so that the fabric can continuously contact the dye in the dye pool to complete the printing and dyeing work; At the same time, a dewatering structure 2 is provided above the dye pool, and the dewatering structure 2 is located between the winding roller 12 and the unwinding roller 11, that is, after the fabric is dyed and before it is wound up by the winding roller 12, the dyed fabric is squeezed by the dewatering structure 2, so as to remove excess dye in the fabric and complete the dewatering of the fabric, thereby avoiding excessive water content in the fabric, and splashing of dye in subsequent processing steps, which wastes dye and affects the sanitary environment of the workshop; and the dewatering structure 2 is located inside the machine body 1, which can fully ensure that when the fabric is squeezed (dewatering the fabric), the dye squeezed out of the fabric can directly fall back into the dyeing pool, preventing the dye from splashing to the outside of the machine body 1 during the squeezing process, and further ensuring the cleanliness and tidiness of the workshop environment.

[0022] Specifically, the dewatering structure 2 includes a first pressing roller 21, a second pressing roller 22, and a lifting assembly 23 for controlling the lifting of the first pressing roller 21 and the second pressing roller 22. The first pressing roller 21 and the second pressing roller 22 move in opposite directions, so that both sides of the fabric can be squeezed, reducing the unevenness caused by single-sided processing, thereby improving the overall quality of the fabric and production efficiency.

[0023] A lifting block 24 is provided between the lifting assembly 23 and the first pressing roller 21, and between the lifting assembly 23 and the second pressing roller 22. In detail, the lifting assembly 23 mainly includes a lifting motor and a lifting screw. The lifting screw is a double-headed screw and is rotatably connected to the machine body 1. Each lifting block 24 is respectively connected to the lifting screw by transmission, and the lifting screw is connected to the output shaft of the lifting motor. When the lifting assembly 23 uses a screw drive to drive the lifting block 24 to move, it can fully withstand and resist the force transmitted along the first pressing roller 21 and the second pressing roller 22, thereby ensuring the load capacity of the lifting assembly 23.

[0024] The lifting motor in this embodiment is preferably a servo motor or other motor with a certain self-locking ability to ensure the stability of the operation of the lifting component 23.

[0025] Auxiliary sliders 25 are provided at one end of the first pressing roller 21 away from the lifting block 24 and at one end of the second pressing roller 22 away from the lifting block 24. Each auxiliary slider 25 is slidably connected to the machine body 1. Both ends of the first pressing roller 21 and both ends of the second pressing roller 22 are rotatably connected to the corresponding lifting block 24 and auxiliary sliders 25. That is, both ends of the first pressing roller 21 and the second pressing roller 22 are rotatably connected to the lifting block 24 and the auxiliary sliders 25, respectively, so that the first pressing roller 21 and the second pressing roller 22 can move synchronously under the action of the lifting assembly 23, ensuring that both sides of the fabric can be evenly squeezed, ensuring the uniformity of squeezing of the dewatering structure 2, and the existence of the auxiliary sliders 25 can make both ends of the first pressing roller 21 or the second pressing roller 22 have support points on the machine body 1, ensuring the stability of the first pressing roller 21 and the second pressing roller 22 when moving and squeezing the fabric.

[0026] Furthermore, the rotational connection between the first pressing roller 21 or the second pressing roller 22 and the lifting block 24 and the auxiliary slider 25 enables the fabric moving under the action of the winding roller 12 to drive the first pressing roller 21 and the second pressing roller 22 to rotate when squeezed by the first pressing roller 21 and the second pressing roller 22, so that the first pressing roller 21 and the second pressing roller 22 can squeeze the fabric more evenly, thereby ensuring the squeezing performance of the water removal structure 2.

[0027] A first telescopic plate 4 is provided between adjacent lifting blocks 24 and between adjacent auxiliary sliding blocks 25. A second telescopic plate 5 is provided at one end of each lifting block 24 away from the first telescopic plate 4 and at one end of each auxiliary sliding block 25 away from the first telescopic plate 4. Each first telescopic plate 4 and each second telescopic plate 5 are preferably a telescopic bellows expansion plate structure made of flexible material, so that the first telescopic plate 4 and each second telescopic plate 5 can be telescoped and extended as each lifting block 24 is lifted and lowered, thereby blocking the movable gap between each lifting block 24 and each auxiliary sliding block 25 on the machine body 1, preventing the dye from splashing into the movable gap and accumulating therein when moving during the fabric dyeing process, causing dye waste, and even the dye may adhere to the lifting screw rod, affecting the normal driving performance of the lifting assembly 23. Example

[0028] like Figure 3~Figure 4 As shown, on the basis of Example 1, a plurality of pressing rings 211 are provided on the first pressing roller 21 of this embodiment, and a plurality of pressing ring grooves 221 are provided on the second pressing roller 22. The existence of each pressing ring 211 and each pressing ring groove 221 reduces the effective area of ​​the first pressing roller 21 and the second pressing roller 22 exerting force on the fabric, thereby increasing the force exerted by the first pressing roller 21 and the second pressing roller 22 on the fabric, thereby improving the squeezing effect of the water removal structure 2; Each pressing ring 211 and each pressing ring groove 221 are correspondingly engaged with each other, so as to avoid mutual interference between the first pressing roller 21 and the second pressing roller 22 during the pressing process, so that the fabric can be squeezed to the maximum extent, and the squeezing effect of the first pressing roller 21 and the second pressing roller 22 on the fabric is ensured; The pressing ring grooves 221 are arranged in sequence along the axial direction of the first pressing roller 21, ensuring the uniform distribution of the pressing ring grooves 221 on the second pressing roller 22 and the pressing rings 211 on the first pressing roller 21, thereby ensuring the uniform pressure on the fabric; the pressing rings 211 are integrally formed with the first pressing roller 21, ensuring the strength of the overall structure of the first pressing roller 21.

[0029] The longitudinal section of each pressing ring groove 221 is an isosceles triangle structure, and because the pressing ring 211 needs to be embedded in the pressing ring groove 221, the longitudinal section of each pressing ring 211 is an isosceles triangle structure, that is, the structural strength of the pressing ring 211 is guaranteed by taking advantage of the high stability and strong bearing capacity of the triangular structure, and avoiding the situation that the structure of each pressing ring 211 itself is deformed by force when applying pressure to the fabric; and each pressing ring 211 is provided with an anti-scratch surface 2111 at one end close to the pressing ring groove 221, and the anti-scratch surface 2111 is an arc structure, that is, the end of the pressing ring 211 that contacts the fabric is an arc structure, which fully prevents the pressing ring 211 from scratching and scratching the fabric when squeezing the fabric, thereby ensuring the safety of fabric dehydration.

[0030] At the same time, a leveling structure 3 is provided between the water removal structure 2 and the winding roller 12. The leveling structure 3 includes a plurality of leveling rollers 31. Each leveling roller 31 is rotatably connected to the machine body 1. A leveling channel for the fabric to pass through is provided between adjacent leveling rollers 31. That is, when the fabric passes through the leveling channel, both sides of the fabric will be squeezed by the leveling rollers 31 with an optical axis structure, which will wrinkle the surface of the fabric, thereby preventing the fabric from being squeezed by the water removal structure 2 and causing wrinkles on the surface, which will affect the subsequent winding flatness.

[0031] In order to improve the dewatering effect, the dewatering structure 2 and the leveling structure 3 are provided with a plurality of them, and each leveling structure 3 is arranged in sequence with the dewatering structure 2 in a linear direction, that is, each dewatering structure 2 is matched with each leveling structure 3 one by one. After a dewatering structure 2 performs dewatering work on the fabric, a leveling structure 3 will then be used to level the fabric, so that the fabric can enter the subsequent processing steps in a flat state, thereby ensuring the processing effect; like Figure 4 , Fig.11 As shown, the first pressing rollers 21 in adjacent water removal structures 2 are staggered, ensuring that both sides of the fabric have the extrusion pressure exerted on them by the pressing ring 211, thereby ensuring the extrusion effect of the fabric in this embodiment; the pressing rings 211 on adjacent first pressing rollers 21 are staggered, ensuring that each point on the fabric has the pressing ring 211 to apply extrusion pressure to it, thereby further improving the extrusion effect of the fabric in this embodiment. Example

[0032] like Figures 5 to 10 As shown, on the basis of Example 1 or Example 2, a driving structure 6 for driving the first pressing roller 21 and the second pressing roller 22 to rotate is provided in this embodiment, so that the rotation of the first pressing roller 21 and the second pressing roller 22 is no longer limited to the linkage relationship with the fabric, so that the first pressing roller 21 and the second pressing roller 22 can both rotate autonomously, thereby improving the squeezing effect of the first pressing roller 21 and the second pressing roller 22 on the fabric.

[0033] The driving structure 6 includes a first driving wheel 61, a second driving wheel 62, a first driving bar 63, a second driving bar 64, and a driving assembly 65. The ends of the first pressing roller 21 and the second pressing roller 22 close to the auxiliary slider 25 penetrate the auxiliary slider 25 and are fixedly connected to the first driving wheel 61 and the second driving wheel 62 respectively, that is, the first pressing roller 21 will be linked with the first driving wheel 61, and the second pressing roller 22 will be linked with the second driving wheel 62. When the first driving wheel 61 and the second driving wheel 62 rotate, the first pressing roller 21 and the second pressing roller 22 will also rotate; and due to the hole-shaft cooperation between the first pressing roller 21, the second pressing roller 22 and each auxiliary slider 25, that is, when each auxiliary slider 25 moves under the action of the lifting assembly 23, the first driving wheel 61 and the second driving wheel 62 will also move; The first driving bar 63 is meshed with the first driving wheel 61, and the second driving bar 64 is meshed with the second driving wheel 62. The driving component 65 is used to drive the first driving bar 63 and the second driving bar 64 to move, that is, under the action of the driving component 65, the first driving bar 63 and the second driving bar 64 will move, thereby driving the first driving wheel 61 and the second driving wheel 62 to rotate, so that the first pressing roller 21 and the second pressing roller 22 rotate to complete the extrusion of the fabric.

[0034] The driving assembly 65 in this embodiment is preferably a linear driver such as a hydraulic cylinder, so as to ensure the smooth movement of the first driving bar 63 and the second driving bar 64.

[0035] A connecting rod 66 is provided between the first driving bar 63 and the second driving bar 64. The first driving bar 63, the second driving bar 64 and the connecting rod 66 are integrally formed to ensure the structural strength among the three. In this way, after the piston rod of the driving assembly 65 is fixedly connected with the connecting rod 66, it is ensured that the driving assembly 65 has a sufficient effective contact area to push the first driving bar 63 and the second driving bar 64 to move, thereby ensuring the stability of the movement of the first driving bar 63 and the second driving bar 64; The first driving bar 63, the second driving bar 64 and the connecting rod 66 are in a "U" shape on a vertical horizontal plane. The "U" shape structure has good bending and shearing resistance, which prevents the first driving bar 63 and the second driving bar 64 from deforming in the process of driving the first pressing roller 21 and the second pressing roller 22 to rotate, thereby affecting the normal rotation of the first pressing roller 21 and the second pressing roller 22.

[0036] Specifically, the first driving wheel 61 includes a first optical wheel 611 and a first gear 612, the second driving wheel 62 includes a second optical wheel 621 and a second gear 622, the first driving bar 63 includes a first optical bar 631 and a first rack 632, and the second driving bar includes a second optical bar 641 and a second rack 642. The first rack 632 meshes with the first gear 612, and the second rack 642 meshes with the second gear 622, that is, the driving structure 6 adopts a gear rack transmission to drive the first pressing roller 21 and the second pressing roller 22 to rotate, because the gear rack transmission can withstand a large load, thereby ensuring that the first pressing roller 21 and the second pressing roller 22 can rotate stably.

[0037] After the first rack 632 and the second rack 642 are respectively located on both sides of the first gear 612 and the second gear 622, during the driving process, the first pressing roller 21 and the second pressing roller 22 can rotate in opposite directions, ensuring that both can apply extrusion force to the fabric in the same direction to ensure the extrusion effect; The diameters of the projection surfaces of the first gear 612 and the second gear 622 on the vertical horizontal plane should be smaller than the width of the projection surface of the auxiliary slider 25 on the vertical horizontal plane, and the first gear 612 and the second gear 622 are staggered in the horizontal plane direction to prevent the first gear 612 and the second gear 622 from meshing when the spacing between adjacent auxiliary sliders 25 is too small, thereby affecting the normal use of this embodiment. Example

[0038] On the basis of Example 3, the driving component 65 in this embodiment should be provided with a laser sensor to detect the extension length of telescopic driving shafts such as piston rods, that is, when the first driving bar 63 and the second driving bar 64 are about to retract under the action of the driving component 65, the laser sensor sends an electrical signal to the lifting motor in the lifting component 23, which is received by the control module of the lifting motor to control the first pressing roller 21 and the second pressing roller 22 to move away from the fabric, thereby reducing the pulling force on the fabric when the first pressing roller 21 and the second pressing roller 22 are reversed, avoiding interference with the normal winding work of the winding roller 12, and improving the stability of the operation of this embodiment.

[0039] Preferably, when the dewatering structure 2 close to the unwinding roller 11 is squeezing the fabric, the dewatering structure 2 far away from the unwinding roller 11 will not squeeze the fabric, thereby ensuring that at least one dewatering structure 2 is dewatering the fabric, thereby ensuring the stability of the dewatering work in this embodiment.

[0040] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
