Description

Technical Field

[0001] This application relates to the field of fabric processing equipment technology, and in particular to a dyeing device for polyester-cotton fabric. Background Technology

[0002] In current dyeing techniques, polyester-cotton fabrics are mostly dyed by placing the fabric in a large dye bath, relying on the dye solution to allow the fabric fibers to adhere the pigment. To ensure the color adhesion and allow the dye solution to fully diffuse into the depths of the fabric, sufficient soaking time is required. Therefore, the dyeing efficiency is relatively limited. Furthermore, due to the surface tension of the dye solution, the fabric tends to float on the surface, requiring workers to push the floating fabric below the liquid surface. This causes wrinkles in the fabric, damaging its crispness. After dyeing, lifting the fabric can easily result in folding, and the fabric fibers tend to stick together, making it difficult to straighten. Summary of the Invention

[0003] The purpose of this application is to provide a dyeing device for polyester-cotton fabrics that has higher dyeing efficiency and is more convenient to use.

[0004] To achieve the above objectives, this application provides a dyeing device for polyester-cotton fabric: It includes a frame with a horizontal plate. A pair of parallel and symmetrical vertical plates are fixedly connected to the lower surface of the horizontal plate. A constraint plate is fixedly connected to one of the vertical plates. A dyeing roller is rotatably connected to the constraint plate and the other vertical plate, suitable for applying dye to the fabric. Several combinations of dyeing rollers and constraint plates are provided. The rotation axes of all dyeing rollers are parallel. A drive mechanism and a feeding mechanism are also provided on the horizontal plate. The drive mechanism is suitable for driving all the dyeing rollers to rotate. The feeding mechanism is suitable for injecting dye through each constraint plate into each dyeing roller. The dyeing rollers pass around the fabric body, and both sides of the polyester-cotton fabric are subjected to the impact pressure of the dye solution, causing the internal fibers to be quickly soaked and adhered, thus improving the dyeing speed.

[0005] As a preferred embodiment, the main body of the coloring roller is a paint roller, which has several overflow channels penetrating the inner and outer walls. One end of the paint roller has a coaxial main shaft, and the longitudinal plate has a shaft hole suitable for the main shaft to pass through to form a rotating pair, thereby restricting the degree of freedom of movement of the coloring roller.

[0006] As a preferred embodiment, the end of the main shaft is fixedly connected to a coaxial gear after passing through the shaft hole, with adjacent gears meshing. The drive mechanism is a geared motor, fixedly connected to the lower surface of the cross plate, and the output end of the drive mechanism is connected to one of the gears, thereby driving all the gears to move in tandem.

[0007] As a preferred embodiment, the other end of the paint roller is provided with a coaxial fitting annular groove, and the constraint plate includes an embedded chuck that rotates with the fitting annular groove. The end face of the embedded chuck facing away from the paint roller has a coaxial insertion part. The end of the insertion part passes through the shaft hole and is also fixedly connected to a connecting plate. The connecting plate is fixedly connected to the longitudinal plate through a connector to ensure the stable installation of the constraint plate.

[0008] As a preferred embodiment, the connecting plate has several through holes arranged equidistantly around the axis, and the outer side of the longitudinal plate has connecting holes corresponding to the through holes. The connecting component is a bolt, which is suitable for threaded engagement with the connecting hole after passing through the through hole, thus taking into account both connection stability and ease of assembly and disassembly.

[0009] As a preferred embodiment, the outer surface of the embedded chuck has a limit ring, which is adapted to abut against the end face of the paint roller to suppress the movement of the paint roller.

[0010] As a preferred embodiment, the feeding mechanism is fixedly connected to the pump body on the upper surface of the horizontal plate. The input end of the pump body is connected to a suction pipe, the lower end of which is submerged below the surface of the pigment liquid. The output end of the pump body is connected to a drain pipe, which branches into several supply branches. The number of supply branches corresponds to the number of constraint plates. One constraint plate is connected to one supply branch, thereby continuously obtaining a supply of dye liquid.

[0011] As a preferred embodiment, the constraint plate has an injection channel that extends through both ends. The end face of the constraint plate also has a pipe connection end that communicates with the injection channel. The pipe connection end is inserted into the liquid supply branch pipe. All the liquid supply branch pipes extend horizontally and are flush with the horizontally extending pipe connection end.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing multiple longitudinally arranged coloring rollers, the polyester-cotton fabric passes around each coloring roller in turn, and the dye liquid is pressurized by a pump body, so that the dye liquid impacts the polyester-cotton fabric, thereby accelerating the diffusion speed of the dye liquid in the polyester-cotton fiber and improving the dyeing efficiency.

[0014] (2) The fabric can remain straight as it passes through the coating roller. No wrinkles will be produced during the dyeing process. There will be no stacking or sticking during the feeding and receiving processes. No sorting is required, saving manpower and further improving dyeing efficiency. It is more convenient and faster to use. Attached Figure Description

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The dyeing equipment for polyester-cotton fabric shown includes a frame 1 fixedly connected to the top of the dyeing tank. The frame 1 has a horizontal plate 101, and a pair of parallel and symmetrical vertical plates 102 are fixedly connected to the lower surface of the horizontal plate 101. Both vertical plates 102 are vertical. A constraint plate 4 is fixedly connected to one of the vertical plates 102. There are several constraint plates 4, which are equidistantly arranged along the vertical direction. Each constraint plate 4 and the other vertical plate 102 are connected to a coloring roller 3 for rotation. Therefore, the number of coloring rollers 3 corresponds to the number of constraint plates 4. That is to say, there are several combinations of coloring rollers 3 and constraint plates 4. In this embodiment, three sets are set. Regardless of how many sets of structures are designed, the rotation axes of all coloring rollers 3 are parallel, so that the polyester-cotton fabric to be dyed can smoothly pass around all the coloring rollers 3.

[0029] The coloring rollers 3 pass around the fabric body 6. In fact, the fabric body 6 not only wraps around the outer side of the coloring rollers 3, but also passes between adjacent coloring rollers 3. The coloring rollers 3 can pressurize the pigment onto the fabric to improve the pigment's penetration into the fabric fibers. The main body of the coloring rollers 3 is a cylindrical paint roller 301, so the fabric body 6 will bend in an S-shape and pass over the paint roller 301. The paint roller 301 has several overflow channels 302 that penetrate the inner and outer walls. These overflow channels 302 are equidistantly arranged along the axial and circumferential directions of the paint roller 301. One end of the paint roller 301 has a coaxial main shaft 303. The longitudinal plate 102 has a shaft hole 103 for the main shaft 303 to pass through to form a rotating pair, which restricts the degree of freedom of movement of the coloring rollers 3.

[0030] The horizontal plate 101 is also equipped with two functional components: a drive mechanism 2 and a feeding mechanism 5. The drive mechanism 2 is used to drive all the coloring rollers 3 to rotate. The end of the main shaft 303 passes through the shaft hole 103 and is fixedly connected to a coaxial gear 304. The number of gears 304 corresponds to the number of coloring rollers 3, and two adjacent gears 304 mesh and can rotate synchronously in opposite directions at the same linear speed. The drive mechanism 2 uses a geared motor with high torque, which can stably provide rotational power. The drive mechanism 2 is fixedly connected to the lower surface of the horizontal plate 101. The output end of the drive mechanism 2 is connected to one of the gears 304. Generally, a coupling can be used for coaxial connection. The gear 304 that is directly driven can drive all other gears 304 to move synchronously.

[0031] The other end of the paint roller 301 is provided with a coaxial engagement groove 305. The constraint disk 4 includes an embedded chuck 401 that rotatably engages with the engagement groove 305. The embedded chuck 401 is embedded in the engagement groove 305 to provide a limiting constraint. The outer surface of the embedded chuck 401 has a limit stop ring 402 to abut against the end face of the paint roller 301 to prevent the paint roller 301 from moving during rotation. The end face of the embedded chuck 401 facing away from the paint roller 301 has a coaxial insertion part 403. The end of the connector is fixedly connected to a connecting plate 405 through the shaft hole 103. The insertion part 403 does not need to rotate relative to the shaft hole 103 because the connecting plate 405 is fixedly connected to the longitudinal plate 102 through the connector 7. The connecting plate 405 has several through holes 406 arranged equidistantly around the shaft, and the outer side of the longitudinal plate 102 has a connecting hole 104 corresponding to the through hole 406. The connector 7 is usually a bolt, which is threaded into the connecting hole 104 after passing through the through hole 406, which takes into account stability and facilitates disassembly and assembly.

[0032] The feeding mechanism 5 injects pigment into each painting roller 3 through each constraint plate 4. Specifically, the feeding mechanism 5 is fixedly connected to a pump body 504 on the upper surface of the horizontal plate 101, which can drive the pigment to flow. The input end of the pump body 504 is connected to a suction pipe 501, the lower end of which is submerged below the surface of the pigment liquid. Atmospheric pressure is used to push the pigment to a higher position. The output end of the pump body 504 is connected to a drain pipe 502, which branches into several supply branches 503. The drain pipe 502 supplies the pigment inside to each supply branch 503 in a roughly uniform manner. The number of 03 corresponds to the number of constraint plates 4. One constraint plate 4 is connected to one liquid supply branch pipe 503, so that each paint roller 301 can obtain sufficient pigment to coat the fabric. In order to ensure that the pigment can enter the paint roller 301, the constraint plate 4 is also provided with a liquid injection channel 404 that runs through both ends. The end face of the constraint plate 4 also has a pipe end 407 that communicates with the liquid injection channel 404. The pipe end 407 is inserted into the liquid supply branch pipe 503 to form a continuous liquid supply channel. All liquid supply branch pipes 503 extend horizontally and are flush with the horizontal pipe end 407.

[0033] Working principle: In use, the fabric body 6 is passed around each coating roller 301 in sequence. Under the constraint of the adjacent coating rollers, the fabric body 6 bends in an S-shape. The drive mechanism 2 is started, which drives the coating roller 301 to rotate through the gear 304. The friction between the coating roller 301 and the fabric body 6 will push the fabric body 6 to move around. At the same time, the pump body 504 is started to draw up the pigment, which is then injected into the coating roller 301 through the drain pipe 502 and the supply branch pipe 503. Due to the large flow velocity of the pigment liquid, it will impact the fabric with a large impact force, together with the weight of the dye liquid itself. The pigment liquid will quickly overflow from one side of the fabric to the other side. Since there are multiple coating rollers 301, the wetting pressure of the pigment liquid will be applied to both sides of the fabric, which can make the pigment quickly penetrate the fibers of the fabric. This not only improves the adhesion efficiency of the pigment, but also maintains the straightness of the fabric, which is convenient for feeding and winding.

[0034] Since both ends of the fabric body 6 generally need to be pulled and cannot be fully dyed when passing through the paint roller 301, the undyed parts at both ends of the fabric body 6 are usually cut off after dyeing. Of course, they can also be re-dyed by soaking.

Those skilled in the art should understand that this application is not limited to the above embodiments.
