Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, and in particular to a fabric printing and dyeing equipment for uniform printing and dyeing. Background Technology

[0002] Fabric dyeing and printing is a process of dyeing and printing on fabrics. Dyeing involves immersing the fabric in a dye bath, allowing dye molecules to penetrate the fibers and give the fabric various colors. Printing, on the other hand, uses specific printing equipment and techniques to transfer designed patterns onto the fabric using dyes or pigments. This process involves multiple steps, including pretreatment, dyeing or printing, and post-treatment. It requires precise control of parameters such as temperature, humidity, and time, depending on the fabric material, dye type, and printing requirements, to ensure that the dyeing and printing results are vibrant, the patterns are clear, and the colorfastness is good. This allows the fabric to have rich colors and diverse patterns to meet the needs of different consumers and various application scenarios.

[0003] Currently, most fabric printing and dyeing equipment has a simple structure and often processes fabrics of a single thickness. When dyeing fabrics of different thicknesses, uneven sizing or poor quality of dyed products can easily occur, affecting the normal use of the equipment. Improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing fabric dyeing equipment, which often has a simple structure, processes fabrics of a single thickness, and tends to produce uneven sizing or poor quality finished products when dyeing fabrics of different thicknesses. Therefore, this invention proposes a fabric dyeing equipment with uniform dyeing properties.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fabric printing and dyeing device for uniform printing and dyeing, comprising a dye box, a guide roller rotatably connected to the inner wall of the dye box, a printing device provided on the surface of the dye box, the printing device comprising a slide, the slide sliding against the upper edge of the dye box, the number of slides being four, the four slides being grouped in pairs, and a roller rotatably connected to the side of each pair of slides that is close to each other, a positioning roller rotatably connected to the inner wall of the dye box, the roller and the positioning roller being at the same height, and one side of the slide... The device is fixedly connected to a protrusion, and a pull rope is fixedly connected to the surface of the protrusion. A guide wheel is rotatably connected to the surface of the dye box, and the pull rope rests on the guide wheel. A push plate is fixedly connected to one end of the two pull ropes that are close to each other. An auxiliary device is provided on the surface of the dye box. The cylinder, push plate, pull rope, protrusion, and tension spring work together to precisely control the distance between the two rollers. This allows the device to easily adapt to the printing and dyeing needs of fabrics of different thicknesses without the need for complicated equipment replacement or adjustment, significantly expanding the applicability of the device and improving its versatility.

[0006] Preferably, the surface of the dye box is fixedly connected to two symmetrically arranged limiting frames, the surface of the push plate is provided with sliding holes, the limiting frames pass through the sliding holes, and the surface of the push plate is slidably connected to the surface of the limiting frames.

[0007] Preferably, a cylinder is fixedly connected to the side of the dye box near the pusher block. The drive end of the cylinder is fixedly connected to the upper surface of the pusher plate. The use of the cylinder simplifies the adjustment process of the roller spacing. The operator only needs to control the extension and retraction of the cylinder to easily complete the adjustment of the roller spacing. The overall operation process of the equipment is clear and simple, which reduces the requirements for the professional skills of the operators and improves work efficiency.

[0008] Preferably, a positioning block is fixedly connected to the upper surface of the dye box, and tension springs are fixedly connected to both sides of the positioning block. The end of the tension spring away from the positioning block is fixedly connected to the surface of the slide. When a batch of fabric is dyed, the cylinder drive end retracts, and under the action of the tension spring, the push plate and slide automatically reset, so that the rollers return to the initial spacing. No manual adjustment is required, saving time and labor costs, and making quick preparations for the next batch of dyeing work.

[0009] Preferably, the longitudinal section of the carriage is "n" shaped.

[0010] Preferably, the auxiliary device includes two receiving hoppers, which are fixedly connected to the two sides of the dye box near the positioning roller. The dye box has a return hole on the side near the receiving hopper, and the return hole is connected to the receiving hopper. After printing and dyeing, the receiving hopper can efficiently collect excess dye dripping from the fabric. The triangular longitudinal section design of the receiving hopper effectively increases the collection area and improves the collection efficiency. The collected dye flows back into the dye box through the return hole, realizing the recycling of dye, greatly reducing dye waste, lowering production costs, and conforming to the concept of environmental protection.

[0011] Preferably, the longitudinal section of the receiving hopper is triangular, which facilitates the guidance of excess dye into the dye box.

[0023] Please see Figures 1-5This utility model provides a technical solution: a fabric printing and dyeing equipment for uniform printing and dyeing, including a dye box 1, a guide roller 2 rotatably connected to the inner wall of the dye box 1, a printing device 3 provided on the surface of the dye box 1, the printing device 3 including a slide 33, the slide 33 sliding with the upper edge of the dye box 1, the number of slides 33 is four, the four slides 33 are in pairs, and a roller 35 is rotatably connected to the side of each pair of slides 33 that is close to each other, a positioning roller 34 is rotatably connected to the inner wall of the dye box 1, the roller 35 and the positioning roller 34 are at the same height, and a protrusion 36 is fixedly connected to one side of the slide 33. A pull rope 37 is fixedly connected to the surface of roller 36, and a guide wheel 310 is rotatably connected to the surface of dye box 1. The pull rope 37 rests on the guide wheel 310, and a push plate 38 is fixedly connected to one end of the two pull ropes 37 that are close to each other. An auxiliary device 4 is provided on the surface of dye box 1. The cylinder 312, push plate 38, pull rope 37, protrusion 36 and tension spring 32 and other components work together to precisely control the distance between the two rollers 35, so that the equipment can easily adapt to the printing and dyeing needs of fabrics of different thicknesses without complicated equipment replacement or adjustment, which significantly broadens the applicability of the equipment and improves its versatility.

[0024] In this embodiment: two symmetrically arranged limiting frames 311 are fixedly connected to the surface of the dye box 1. The surface of the push plate 38 is provided with a sliding hole 39. The limiting frame 311 passes through the sliding hole 39, and the push plate 38 is slidably connected to the surface of the limiting frame 311.

[0025] Specifically, a cylinder 312 is fixedly connected to the side of the dye box 1 near the pusher block. The drive end of the cylinder 312 is fixedly connected to the upper surface of the pusher plate 38. The use of the cylinder 312 simplifies the adjustment process of the gap between the rollers 35. The operator only needs to control the extension and retraction of the cylinder 312 to easily complete the adjustment of the gap between the rollers 35. The overall operation process of the equipment is clear and simple, which reduces the requirements for the professional skills of the operators and improves work efficiency.

[0026] In this embodiment: a positioning block 31 is fixedly connected to the upper surface of the dye box 1, and tension springs 32 are fixedly connected to both sides of the positioning block 31. The end of the tension spring 32 away from the positioning block 31 is fixedly connected to the surface of the slide 33. When a batch of fabric is dyed, the cylinder 312 retracts. Under the action of the tension spring 32, the push plate 38 and the slide 33 automatically reset, so that the roller 35 returns to the initial spacing. No manual adjustment is required, saving time and labor costs, and making quick preparations for the next batch of dyeing work.

[0027] Specifically, the longitudinal section of carriage 33 is "n" shaped.

[0028] Specifically, the auxiliary device 4 includes two receiving hoppers 41. The two receiving hoppers 41 are fixedly connected to the two sides of the dye box 1 near the positioning roller 34. The dye box 1 has a return hole 42 on the side near the receiving hopper 41, and the return hole 42 is connected to the receiving hopper 41. After the printing and dyeing is completed, the receiving hopper 41 can efficiently collect the excess dye dripping from the fabric. The triangular longitudinal section design of the receiving hopper 41 effectively increases the collection area and improves the collection efficiency. The collected dye flows back into the dye box 1 through the return hole 42, realizing the recycling of dye, greatly reducing dye waste, reducing production costs, and conforming to the concept of environmental protection.

[0029] Specifically, the longitudinal section of the receiving hopper 41 is triangular, which facilitates the guidance of excess dye into the dye box 1.

[0030] Working principle: One end of the fabric to be printed is wrapped around the guide roller 2 and then guided between the positioning roller 34 and the padding roller 35. The rotation of the guide roller 2 helps the fabric to enter the equipment smoothly, avoiding jamming or tangling during the feeding process.

[0031] When cylinder 312 is activated, its drive end pushes push plate 38 down along limit frame 311. Push plate 38 moves protrusion 36 via pull rope 37, causing slide 33 to slide along the upper edge of dye box 1. Under the elastic action of tension spring 32, the position of slide 33 can be flexibly adjusted, achieving precise control of the distance between the two rollers 35 to adapt to the dyeing needs of fabrics of different thicknesses.

[0032] As the fabric is continuously fed, the roller 35 rotates and evenly transfers the dye from the dye box 1 onto the fabric. Since the roller 35 and the positioning roller 34 are at the same height, the positioning roller 34 provides stable support for the fabric, ensuring that the fabric remains flat during the printing process, thereby achieving uniform dyeing.

[0033] After dyeing is completed, excess dye on the fabric will drip off as the fabric moves. The receiving hopper 41 is installed on both sides of the dye tank 1 near the positioning roller 34. Its triangular cross-section design effectively collects the dripping dye. The dye flows back into the dye tank 1 through the return hole 42, achieving dye recycling and reducing dye waste.

[0034] After a batch of fabric is printed and dyed, the cylinder 312 retracts, and the push plate 38 moves upward under the tension of the tension spring 32. The push plate 38 drives the slide 33 to reset through the pull rope 37, so that the roller 35 returns to the initial spacing, preparing for the next batch of fabric printing and dyeing.
