Description

Technical Field

[0001] This utility model relates to the technical field of dyeing and bleaching equipment, specifically to a continuous feeding mechanism for dyeing and bleaching equipment. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. Blended fabrics, also known as blended synthetic fiber fabrics, are textile products made by mixing chemical fibers with other natural fibers such as cotton, wool, silk, and linen. They possess both the style of polyester and the advantages of cotton fabrics, such as polyester-cotton fabric and polyester-wool gabardine. Dyeing is a process in the production of blended fabrics.

[0003] The Chinese patent announcement with publication number CN216107643U discloses a dyeing and bleaching equipment for blended fabric production. The key technical features are: a box body, an inverted U-shaped cover arranged horizontally fixedly connected to the upper end of the box body, a gantry frame arranged horizontally fixedly connected to the middle of the upper end of the inverted U-shaped cover, a movable plate attached to the upper end of the inverted U-shaped cover, a fixed part of a lifting device fixedly connected to the middle of the upper end of the gantry frame, and multiple vertically arranged connecting rods fixedly connected at equal intervals to the lower end of the movable plate. The lower ends of the connecting rods pass through the inverted U-shaped cover and are fixedly connected to a movable roller assembly.

[0004] In the above scheme, the fabric is fed into the box by a moving roller assembly and then bleached by the dyeing solution inside the box. This has the following disadvantage: the equipment does not have a feeding mechanism, so the dyeing solution cannot be automatically and continuously supplied to the fabric during the dyeing process. Utility Model Content

[0005] The purpose of this invention is to provide a continuous feeding mechanism for a bleaching and dyeing equipment, so as to solve the problem that the equipment does not have a feeding mechanism, which makes it impossible to automatically and continuously supply the bleaching and dyeing solution to the fabric during the bleaching and dyeing process.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a continuous feeding mechanism for a dyeing and bleaching equipment, comprising two guide rollers, the two guide rollers being rotatably disposed inside a dyeing and bleaching tank, a first electric push rod fixed to the bottom surface of the dyeing and bleaching tank, a lifting plate fixed to one end of the telescopic rod of the first electric push rod, an mounting plate detachably mounted on the top surface of the dyeing and bleaching tank, an infrared sensor fixed to the bottom surface of the mounting plate, a pressure sensor fixed to the bottom surface of the mounting plate, a contact rod fixed to the top surface of the lifting plate, a conveying pump fixed to the front side of the outer wall of the dyeing and bleaching tank, a connecting pipe fixedly connected between the output end of the conveying pump and the dyeing and bleaching tank, a conveying pipe fixed to the input end of the conveying pump, and a PLC controller fixed to the front side of the outer wall of the dyeing and bleaching tank. The first electric push rod, the infrared sensor, the pressure sensor, and the conveying pump are all electrically connected to the PLC controller.

[0007] Preferably, the bottom surface of the dyeing tank is fixed with two limiting cylinders, and the bottom surface of the lifting plate is fixed with two limiting posts, and the two limiting posts are slidably inserted into the two limiting cylinders respectively.

[0008] Preferably, a sealing ring is fixed to the outer wall of the lifting plate.

[0009] Preferably, the top surface of the dyeing tank is provided with a threaded groove, and the top surface of the mounting plate is provided with a threaded hole. A bolt is threadedly connected to the threaded hole, and the threaded end of the bolt is threadedly connected to the inside of the threaded groove.

[0010] Preferably, the top surface of the dyeing tank is fixed with two support plates, and an upper pressure roller is rotatably arranged between the two support plates. A motor is fixed to the front side of the front support plate. The motor is electrically connected to a PLC controller. The output shaft of the motor passes through the front support plate and is fixedly connected to the front end of the upper pressure roller. A lower pressure roller is rotatably arranged between the two support plates.

[0011] Preferably, each of the two support plates has a movable hole on its front side, and a second electric push rod is fixed to the bottom surface of each of the two movable holes. The second electric push rod is electrically connected to the PLC controller, and a movable seat is fixed to one end of each of the two second electric push rod telescopic rods. The lower pressure roller is rotatably arranged between the two movable seats.

[0012] Compared with existing technologies, the continuous feeding mechanism of a dyeing and bleaching equipment that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] I. In use, through the coordinated action of guide rollers, dyeing tank, first electric push rod, lifting plate, mounting plate, infrared sensor, pressure sensor, contact rod, conveying pump, connecting pipe, conveying pipe and PLC controller, the automatic and continuous supply of dyeing solution to the fabric during the dyeing process is realized, reducing manual intervention, reducing labor intensity, and ensuring that the dyeing process is always carried out in a stable solution environment, effectively improving the dyeing quality of the fabric, while avoiding resource waste caused by insufficient or excessive solution;

[0014] II. During use, when the lifting plate is raised and lowered by the first electric push rod, the limiting post slides inside the limiting cylinder to limit the lifting plate, ensuring that it does not shift or shake during the raising and lowering process. This effectively prevents the bleaching solution from flowing into the bottom of the lifting plate, avoiding corrosion and damage to the first electric push rod, and extending its service life. During installation, simply place the mounting plate in the appropriate position, align the threaded hole with the threaded groove, and then tighten the bolts to complete the installation, facilitating maintenance or replacement.

[0015] Third, during use, it can effectively remove excess bleaching solution from the fabric, avoiding waste caused by excessive solution carried out by the fabric, and also reducing the burden of subsequent drying processes, thus improving production efficiency. The telescopic rod of the second electric pusher pushes the moving seat up and down, driving the lower pressure roller to rise and fall, thereby adjusting the distance between the lower and upper pressure rollers, allowing the feeding mechanism to adapt to the processing needs of fabrics of different thicknesses.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a continuous feeding mechanism for a dyeing and bleaching equipment includes two guide rollers 1, which are rotatably disposed inside a dyeing and bleaching tank 2. A first electric push rod 3 is fixed to the bottom surface of the dyeing and bleaching tank 2. A lifting plate 4 is fixed to one end of the telescopic rod of the first electric push rod 3. An mounting plate 5 is detachably installed on the top surface of the dyeing and bleaching tank 2. An infrared sensor 6 (model OMRON E3Z) is fixed to the bottom surface of the mounting plate 5. A pressure sensor 7 is fixed to the bottom surface of the mounting plate 5. A contact rod 8 is fixed to the top surface of the lifting plate 4. A conveying pump 9 is fixed to the front side of the outer wall of the dyeing and bleaching tank 2. A connecting pipe 10 is fixed between the output end of the conveying pump 9 and the dyeing and bleaching tank 2. A conveying pipe 11 is fixed to the input end of the conveying pump 9. A PLC controller 12 (model Siemens S7-200) is fixed to the front side of the outer wall of the dyeing and bleaching tank 2. The first electric push rod 3, the infrared sensor 6, the pressure sensor 7, and the conveying pump 9 are all electrically connected to the PLC controller 12.

[0023] In use, the staff first injects the bleaching solution into the bleaching tank 2, so that the bleaching solution is on the lifting plate 4, and at the same time, the two guide rollers 1 are completely immersed in the bleaching solution. Then the staff passes the fabric through the bottom of the two guide rollers 1 and conveys it to the left.

[0024] During the fabric pulling process, the fabric enters the dyeing tank 2 for dyeing treatment. As the dyeing continues, the dyeing solution decreases. At this time, the infrared sensor 6 on the mounting plate 5 monitors the liquid level of the dyeing solution in real time and transmits the data to the PLC controller 12 in a timely manner. When the liquid level is detected to be low, the PLC controller 12 starts the first electric push rod 3. The first electric push rod 3 pushes the lifting plate 4 to move upward, which drives the dyeing solution to rise accordingly, ensuring that the guide roller 1 is always immersed in the dyeing solution. This avoids the fabric from being unable to be dyed properly due to the liquid level being lower than the bottom of the guide roller 1, and eliminates the need for staff to manually replenish the dyeing solution multiple times.

[0025] As the lifting plate 4 rises, the contact rod 8 also moves upward. When the top of the contact rod 8 moves to a certain position and squeezes the pressure sensor 7, it indicates that the dyeing solution is about to run out. The pressure sensor 7 quickly transmits this information to the PLC controller 12, and the PLC controller 12 immediately starts the delivery pump 9. The delivery pump 9 draws the dyeing solution from the outside through the delivery pipe 11 and then delivers it to the dyeing tank 2 through the connecting pipe 10 for replenishment. At the same time, as the dyeing solution is replenished, the first electric push rod 3 drives the lifting plate 4 to gradually move downward and reset.

[0026] Through the coordinated action of guide roller 1, dyeing tank 2, first electric push rod 3, lifting plate 4, mounting plate 5, infrared sensor 6, pressure sensor 7, contact rod 8, conveying pump 9, connecting pipe 10, conveying pipe 11 and PLC controller 12, the automatic and continuous supply of dyeing solution to the fabric during the dyeing process is realized, reducing manual intervention, lowering labor intensity, and ensuring that the dyeing process is always carried out in a stable solution environment, effectively improving the dyeing quality of the fabric, while avoiding resource waste caused by insufficient or excessive solution.

[0027] like Figures 1-3 As shown, two limiting cylinders 13 are fixed to the bottom surface of the dyeing tank 2, and two limiting columns 14 are fixed to the bottom surface of the lifting plate 4. The two limiting columns 14 are slidably inserted into the two limiting cylinders 13.

[0028] In use, when the lifting plate 4 is raised or lowered by the first electric push rod 3, the limiting post 14 is slidably inserted inside the limiting cylinder 13, which can limit the lifting plate 4 and ensure that the lifting plate 4 will not deviate or shake during the raising or lowering process.

[0029] like Figure 1 and Figure 2 As shown, a sealing ring 15 is fixed to the outer wall of the lifting plate 4, a threaded groove 16 is provided on the top surface of the dyeing tank 2, and a threaded hole 17 is provided on the top surface of the mounting plate 5. A bolt 18 is threadedly connected to the threaded hole 17, and the threaded end of the bolt 18 is connected to the internal thread of the threaded groove 16.

[0030] During use, as the lifting plate 4 rises and falls, the sealing ring 15 tightly adheres to the inner wall of the dyeing tank 2, sealing the gap between the lifting plate 4 and the dyeing tank 2. This effectively prevents the dyeing solution from flowing into the bottom of the lifting plate 4, avoiding corrosion and damage to the first electric push rod 3 and extending its service life. When maintenance or replacement of the infrared sensor 6 or pressure sensor 7 is required, the operator only needs to unscrew the bolt 18 to remove it from the threaded hole 17 and threaded groove 16, thus removing the mounting plate 5 from the top surface of the dyeing tank 2 for easy sensor operation. During installation, the mounting plate 5 is placed in the appropriate position, aligning the threaded hole 17 with the threaded groove 16, and then the bolt 18 is screwed in to complete the installation, facilitating maintenance or replacement.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, two support plates 19 are fixed to the top surface of the dyeing tank 2. An upper pressure roller 20 is rotatably arranged between the two support plates 19. A motor 21 is fixed to the front side of the front support plate 19. The motor 21 is electrically connected to the PLC controller 12. The output shaft of the motor 21 passes through the front support plate 19 and is fixedly connected to the front end of the upper pressure roller 20. A lower pressure roller 22 is rotatably arranged between the two support plates 19. Movable holes 23 are opened on the front side of both support plates 19. A second electric push rod 24 is fixed to the bottom surface of the two movable holes 23 respectively. The second electric push rod 24 is electrically connected to the PLC controller 12. One end of the telescopic rod of the two second electric push rods 24 is fixed to a movable seat 25 respectively. The lower pressure roller 22 is rotatably arranged between the two movable seats 25.

[0032] In operation, the operator passes the fabric from right to left through the bottom of the two guide rollers 1, then through the upper pressure roller 20 and the lower pressure roller 22. Subsequently, the PLC controller 12 starts the motor 21, whose output shaft drives the upper pressure roller 20 to rotate. The upper and lower pressure rollers 20 work together to squeeze the fabric, expelling excess dyeing solution. The expelled solution falls back into the dyeing tank 2 under gravity, effectively removing excess solution and avoiding waste caused by excessive solution carried out by the fabric. This also reduces the burden of subsequent drying and improves production efficiency. When processing fabrics of different thicknesses, the operator activates two second electric push rods 24 via the PLC controller 12. The telescopic rods of the second electric push rods 24 push the moving seat 25 up and down, causing the lower pressure roller 22 to rise and fall, thus adjusting the distance between the lower pressure roller 22 and the upper pressure roller 20. This allows the feeding mechanism to adapt to the processing needs of fabrics of different thicknesses.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
