Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of printing and dyeing equipment, and in particular to a printing and dyeing equipment and a printing and dyeing process thereof. Background Art
[0002] Printing and dyeing usually refers to a processing method for cloth and fabrics. The existing processing methods are mainly divided into two types: immersion dyeing and spray dyeing.
[0003] Among them, the immersion dyeing method usually involves completely immersing the fabric or cloth in the dye solution, and the dye is evenly colored through its adsorption effect. Therefore, the use of this method requires a large amount of dye, and some dye is not adsorbed and remains in the dye solution, causing waste. The spray dyeing method, on the other hand, atomizes the dye through a nozzle and sprays it directly onto the fabric, effectively reducing dye waste. However, when dyeing some water-repellent fabrics (such as coated fabrics) using this method, the poor adsorption of the fabric leads to uneven penetration of the dye on the fabric, affecting the dyeing effect. Summary of the Invention
[0004] The main purpose of the present invention is to provide a printing and dyeing device and a printing and dyeing process thereof, aiming to solve the problems of easy waste of dye and uneven penetration of dye during the dyeing process in the related art.

The first extrusion liquid delivery roller and the second extrusion liquid delivery roller are both rotatably connected to the dyeing frame; the first extrusion liquid delivery roller and the second extrusion liquid delivery roller are both provided with an extrusion liquid delivery structure; and a lifting mechanism for controlling the lifting and lowering of the second extrusion liquid delivery roller is provided between the dyeing frame and the second extrusion liquid delivery roller.
[0006] Furthermore, the liquid extrusion structure includes a liquid supply channel, a plurality of liquid outlets, and a plurality of pressure-bearing parts for linkage with the fabric to be dyed. Each of the pressure-bearing parts is slidingly connected to each liquid outlet one by one. Each of the liquid outlets is connected to the liquid supply channel and is evenly distributed around the first liquid extrusion roller or the second liquid extrusion roller.
[0007] Furthermore, the projection surfaces of the pressure-bearing members in the axial direction of the first liquid extrusion roller and the second liquid extrusion roller are all circular structures.
[0008] Furthermore, the first liquid extrusion roller and the second liquid extrusion roller are each provided with a plurality of them, and each of the first liquid extrusion rollers and the second liquid extrusion rollers are arranged in sequence along a linear direction, and each of the liquid outlets and the pressure-bearing parts are arranged in sequence along the axial direction of the first liquid extrusion roller or the second liquid extrusion roller, and the pressure-bearing parts on adjacent first liquid extrusion rollers and adjacent second liquid extrusion rollers are staggered and spaced apart.
[0009] Furthermore, the liquid outlets are interconnected, and connecting channels are provided between the liquid outlets, and the pressure-bearing parts are integrally formed with each other.
[0010] Furthermore, a connecting column is provided for integrating the pressure-bearing parts with each other, and sliding blocks are provided on both sides of the connecting column. The connecting column is rotatably connected to the sliding blocks, and each of the sliding blocks is slidingly connected to the first extrusion liquid roller or the second extrusion liquid roller. An elastic member is provided between the sliding block and the first extrusion liquid roller or the second extrusion liquid roller.
[0011] Furthermore, the lifting mechanism includes a lifting block and a lifting hydraulic cylinder. The dyeing rack is provided with a sliding groove. The lifting block and the lifting hydraulic cylinder are both located in the sliding groove. The second liquid extrusion roller is rotatably connected to the lifting block.
[0012] Furthermore, the dyeing frame is provided with a liquid supply seat, the first liquid extrusion roller and the second liquid extrusion roller are both connected to the liquid supply seat, and a corrugated telescopic tube is provided between the second liquid extrusion roller and the liquid supply seat, and the central axis of the corrugated telescopic tube is perpendicular to the horizontal plane.
[0013] Furthermore, the first liquid extrusion roller and the second liquid extrusion roller both include a connecting rotating shaft, and the first liquid extrusion roller also includes a limiting plate.
[0014] A printing and dyeing process compatible with the above-mentioned printing and dyeing equipment includes the following steps: S1: material preparation, preparing the fabric to be dyed; S2: equipment adjustment, adjusting the distance between the first extrusion liquid discharge roller and the second extrusion liquid discharge roller according to the size of the fabric to be dyed; S3: dyeing, allowing the fabric to be dyed to enter the dyeing device, dyeing the fabric, and winding the fabric by a winding roller located at the outlet of the dyeing device; S4: material removal, removing the dyed fabric and storing it or sending it to the production equipment for the next processing step. The working principle and beneficial effects of the present invention are: The invention mainly comprises a dyeing device, which comprises a first liquid squeezing roller, a second liquid squeezing roller and a dyeing frame for supporting the first and second liquid squeezing rollers.

[0020] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. Example
[0022] like Figure 1 As shown, this embodiment proposes a printing and dyeing equipment, which mainly includes a dyeing device 1 and a supporting workbench. The dyeing device 1 is located on the supporting workbench, that is, with the support of the supporting workbench, the dyeing device 1 is at a horizontal height that is convenient for the staff to operate, thereby making it convenient for the staff to use this embodiment.
[0023] Specifically, the dyeing device 1 mainly includes a first extrusion liquid delivery roller 11, a second extrusion liquid delivery roller 12, and a dyeing frame 13. The dyeing frame 13 is symmetrically and evenly distributed around the first extrusion liquid delivery roller 11 and the second extrusion liquid delivery roller 12 and is fixedly connected to the supporting workbench. That is, the dyeing frame 13 plays a role in supporting each extrusion liquid delivery roller (the first extrusion liquid delivery roller 11 and the second extrusion liquid delivery roller 12).
[0024] The first and second extrusion rollers 11, 12 are both rotatably connected to the dyeing frame 13, with a gap between them to allow the fabric to pass through. This gap should be smaller than the thickness of the fabric. This allows the fabric to contact the radial surfaces of the extrusion rollers, driving them to rotate, effectively squeezing the fabric. This squeezing action also expands the fiber arrangement on the fabric surface, allowing the dye supplied in this embodiment to more easily penetrate the fabric, effectively improving the dyeing effect.
[0025] The first liquid squeezing roller 11 and the second liquid squeezing roller 12 are both provided with a liquid squeezing structure 2, which is linked to the fabric to be dyed. That is, dye will only adhere to the fabric after the fabric comes into contact with the liquid squeezing structure 2, effectively avoiding excessive use of dye and waste of dye.
[0026] A dye recovery box should be provided below the first and second extrusion rollers 11 and 12 to prevent the dye from dripping and flowing along the surface of the supporting workbench during the dyeing process, thereby polluting the surrounding area and the hygiene of the equipment.
[0027] Specifically, such as Figures 5-7 As shown, the liquid extrusion structure 2 includes a liquid supply channel 21, a plurality of liquid outlets 22, and a plurality of pressure-bearing members 23 for interlocking with the fabric to be dyed. Each pressure-bearing member 23 is slidably connected to each liquid outlet 22 in a one-to-one correspondence. Each liquid outlet 22 is connected to the liquid supply channel 21. When the pressure-bearing member 23 contacts the fabric, it is forced to move (the external force is greater than the pressure of the dye at the liquid outlet 22 acting on the pressure-bearing member 23), thereby opening the liquid outlet 22 (canceling the closure of the liquid outlet 22), allowing the dye and dye in the liquid supply channel 21 to flow out along the liquid outlet 22 and adhere to the fabric.
[0028] Each liquid outlet 22 and each pressure member 23 is evenly distributed around the first liquid extrusion roller 11 or the second liquid extrusion roller 12 to avoid the existence of a liquid outlet dead angle due to the rotation of the first liquid extrusion roller 11 or the second liquid extrusion roller 12.
[0029] Furthermore, in this embodiment, there are multiple first extrusion liquid delivery rollers 11 and second extrusion liquid delivery rollers 12, and each first extrusion liquid delivery roller 11 and each second extrusion liquid delivery roller 12 are arranged in sequence along the linear direction. Each liquid outlet 22 and each pressure member 23 are arranged in sequence along the axial direction of the first extrusion liquid delivery roller 11 or the second extrusion liquid delivery roller 12, and the pressure members 23 on adjacent first extrusion liquid delivery rollers 11 and adjacent second extrusion liquid delivery rollers 12 are staggered and spaced apart. That is, by complementing each other with multiple groups of first extrusion liquid delivery rollers 11 and second extrusion liquid delivery rollers 12, it is ensured that the liquid delivery range of this embodiment can accurately cover the cloth (cloth width).
[0030] The projections of each pressure member 23 on the axial direction of the first and second liquid extrusion rollers 11, 12 are circular, resulting in an arc-shaped contact surface between the pressure member 23 and the fabric. This prevents the fabric from being damaged or scratched due to prolonged contact with the pressure member 23 during movement. Preferably, each pressure member 23 is spherical, so that upon contact with the fabric, the pressure member 23 can maintain contact with the fabric in a rolling motion, effectively reducing friction between the two.
[0031] At the same time, if Figures 1 to 4As shown, a lifting mechanism 3 for controlling the lifting and lowering of the second extrusion liquid roller 12 is provided between the dyeing frame 13 and the second extrusion liquid roller 12. That is, under the action of the lifting mechanism 3, the distance between the first extrusion liquid roller 11 and the second extrusion liquid roller 12 can be changed by moving the second extrusion liquid roller 12, so that this embodiment can be adapted to fabrics of various thicknesses and expand the scope of use of this embodiment; and the way in which the fabric is subjected to the extrusion force can be changed by reducing or expanding the distance between the two, so that the dyeing effect of the fabric can be changed. The specific changes should be determined according to actual production needs and will not be described in detail in this embodiment.
[0032] Specifically, the lifting mechanism 3 includes a lifting block 31 and a lifting hydraulic cylinder 32. A sliding groove 131 is provided on the dyeing frame 13. The lifting block 31 and the lifting hydraulic cylinder 32 are both located in the sliding groove 131, wherein the lifting block 31 is slidingly connected to the sliding groove 131; the lifting hydraulic cylinder 32 is fixedly connected to the sliding groove 131, and the lifting block 31 itself is fixedly connected to the piston rod of the lifting hydraulic cylinder 32. In this way, the lifting block 31 can be driven to move by controlling the lifting hydraulic cylinder 32. The second liquid extrusion roller 12 is rotationally connected to the lifting block 31 to prevent the connection between the second liquid extrusion roller 12 and the lifting block 31 from affecting its own rotational movement. Correspondingly, a second rotating hole for the rotational connection of the second liquid extrusion roller 12 is provided on the lifting block 31; and a first rotating hole for the rotational connection of the first liquid extrusion roller 11 is provided on the dyeing frame 13.
[0033] Preferably, a sealing ring is provided between each first liquid extrusion roller 11 and each first rotating hole, and between each second liquid extrusion roller 12 and each second rotating hole to prevent leakage of the dye liquid.
[0034] If necessary, a rotary joint may be provided between each first liquid extrusion roller 11 and each first rotating hole, and between each second liquid extrusion roller 12 and each second rotating hole to further improve the sealing performance of the first liquid extrusion roller 11 and the second liquid extrusion roller 12 during rotation.
[0035] In order to provide dye solution for each liquid extrusion roller, a liquid supply seat 4 is provided on the dyeing frame 13 in this embodiment. A liquid supply main channel is provided in the liquid supply seat 4. Each first liquid extrusion roller 11 and each second liquid extrusion roller 12 are connected to the liquid supply main channel. The liquid supply seat 4 is equipped with a liquid storage tank and a liquid supply pump for transporting the liquid in the liquid storage tank to the liquid supply seat 4 (in the liquid supply main channel). The specific model of the liquid supply pump and how it is connected to the liquid storage tank and the liquid supply seat 4 should be determined according to the model required for actual production, and will not be described in detail in this embodiment.
[0036] Taking into account, a bellows telescopic tube 5 is provided between the second liquid extrusion roller 12 and the liquid supply seat 4, that is, the bellows telescopic tube 5 is used as a connecting pipe between each second liquid extrusion roller 12 and the liquid supply seat 4, which effectively avoids the connecting pipe between the two affecting the lifting movement of the second liquid extrusion roller 12. The central axis of the bellows telescopic tube 5 is perpendicular to the horizontal plane, so that the bellows telescopic tube 5 deforms as the second liquid extrusion roller 12 moves.
[0037] Correspondingly, the lifting block 31 is equipped with connecting pipes for connecting to the bellows 5. These connecting pipes communicate with the second rotation hole (liquid supply channel 21). Mounting plates are located on either side of each connecting pipe. These plates are fixedly connected to the sliding groove 131 and provide mounting locations for the lifting hydraulic cylinder 32. A gap is left between adjacent mounting plates. As the lifting block 31 moves, the connecting pipes on the lifting block 31 can move within this gap, preventing interference with the movement of the lifting block 31.
[0038] The first liquid extrusion roller 11 and the second liquid extrusion roller 12 both include a connecting rotating shaft 14 and a contact shaft. Each liquid extrusion structure 2 is located on the contact shaft. The diameter of the connecting rotating shaft 14 is smaller than the diameter of the contact shaft. Correspondingly, the connecting rotating shaft 14 is rotatably connected to the second rotating hole, thereby avoiding interference between the lifting block 31 and the first liquid extrusion roller 11 (the opening of the sliding groove 131 destroys the structural structure of the first rotating hole), thereby maximizing the moving stroke of the second liquid extrusion roller 12.
[0039] Each first liquid extrusion roller 11 also includes two limit plates 6, each limit plate 6 is fixedly arranged on the connecting rotating shaft 14 of the first liquid extrusion roller 11, and is symmetrically and evenly distributed with the contact axis as the center. In this way, it can not only prevent the cloth located on the contact axis from moving left and right, but also can abut against the connecting rotating shaft 14 of the second liquid extrusion roller 12 when each second liquid extrusion roller 12 moves to the lowest position, provide support for it, and ensure the stability of the rotation of the second liquid extrusion roller 12. Example
[0040] On the basis of Example 1, Figures 8-10 As shown, this embodiment proposes that the liquid outlets 22 are interconnected, and a connecting channel 24 is provided between each liquid outlet 22. In this way, if the connecting pipeline between one liquid outlet 22 and the liquid supply channel 21 is blocked, the dye liquid in the other liquid outlets 22 can be replenished through the connecting channel 24, effectively avoiding the occurrence of points on the extrusion liquid outlet roller where liquid is not discharged. Correspondingly, the pressure-bearing members 23 are integrally formed with each other to ensure the sealing effect of the interconnected liquid outlets 22.
[0041] Preferably, a connecting column 25 is provided for integrating the pressure-bearing parts 23 with each other, that is, the pressure-bearing parts 23 are formed into a columnar structure after being integrated with each other, and sliding blocks 26 are provided on both sides of the connecting column 25. The connecting column 25 is rotatably connected to the sliding blocks 26, and each sliding block 26 is slidingly connected to the first extrusion liquid roller 11 or the second extrusion liquid roller 12. An elastic member 27 is provided between the sliding block 26 and the first extrusion liquid roller 11 or the second extrusion liquid roller 12. With the help of the elastic action of the elastic member 27, each pressure-bearing part 23 is assisted to quickly reset, thereby ensuring the real-time sealing of each pressure-bearing part 23 for each liquid outlet 22.
[0042] Correspondingly, each liquid extrusion roller is provided with an installation cavity for installing the sliding block 26 and the elastic member 27, and a movable groove for the sliding of the connecting column 25. The installation cavity is interconnected with the liquid supply channel 21 to avoid accumulation of dye liquid in the installation cavity, which affects the deformation of the elastic member 27 and the normal movement of the sliding block 26. Example
[0043] On the basis of Example 2 or Example 1, Figure 11 As shown, in this embodiment, the pressure-bearing parts 23 and the liquid outlets 22 are grouped. The pressure-bearing parts 23 of each group are integrally formed with each other and are equipped with elastic parts 27 and sliding blocks 26. The liquid outlets 22 of each group are integrally formed with each other, that is, the columnar structure in Example 2 is divided into several columns, which effectively reduces the load on the elastic parts 27 and makes it more convenient for the elastic parts 27 to quickly reset the columns.
[0044] Correspondingly, the cylinders on adjacent liquid extrusion rollers are staggered to avoid coloring dead corners on the fabric. Example
[0045] This embodiment proposes a printing and dyeing process compatible with any of the above embodiments, comprising the following steps: S1: Prepare the fabrics to be dyed; S2: Equipment adjustment: According to the size of the fabric to be dyed, the distance between the first extrusion roller 11 and the second extrusion roller 12 is adjusted to ensure that the first extrusion roller 11 and the second extrusion roller 12 in the dyeing device 1 can exert the most appropriate extrusion force on the fabric after cooperating with each other to ensure the dyeing effect; S3: Dyeing, the fabric to be dyed enters the dyeing device 1, is dyed, and is wound up by a winding roller located at the exit of the dyeing device 1. That is, the movement of the fabric in this embodiment is controlled by the winding roller. Relying on a single moving structure for movement can effectively ensure that the fabric moves at a relatively stable speed, thereby ensuring processing stability; S4: Removing the dyed fabric and storing it or sending it to the next processing equipment to complete the fabric dyeing process. Preferably, a drying device should be provided on the support workbench, and the drying device should be located between the dyeing device 1 and the winding roller. That is, during the winding process, the dyed fabric enters the drying device, and by drying the fabric, the color of the fabric is fixed and the dyed fabric is prevented from fading.
