Description

Technical Field

[0001] This utility model relates to the technical field of fabric production equipment, specifically a dyeing and printing device. Background Technology

[0002] Utility model patent CN221523040U discloses a dyeing and printing device for shirt processing. The device includes a dyeing tank, with a first dyeing roller and a second dyeing roller movably mounted on the lower side of the tank's interior. Guide rollers are movably mounted on the upper sides of both the first and second dyeing rollers, and shirt fabric is covered on both rollers. In this invention, the fabric bypasses the guide rollers and dyeing rollers in the dyeing tank, and is dyed by the dyeing agent within the tank.

[0003] However, because the guide rollers and dyeing rollers in this invention are in fixed positions, and the guide rollers are immersed in the dyeing agent, workers must manually insert their hands deep into the dyeing bath and submerge their hands in the dyeing agent when threading the fabric. This process is extremely inconvenient and inefficient.

[0004] Therefore, this utility model proposes a technical solution to solve the problem of inconvenience in the process of weaving fabric. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing and dyeing device, which aims to achieve the technical effect of faster and more convenient fabric threading and improved work efficiency.

[0006] A dyeing and printing apparatus includes a dyeing and printing apparatus body, the dyeing and printing apparatus body including a dyeing pool loaded with dye, two guide rollers located above the surface of the dye liquid and two dyeing rollers submerged in the dye, the dyeing pool being a cylindrical structure with an open top, and the left and right sides of the dyeing pool having an outlet and an inlet respectively, the two guide rollers being rotatably connected between the inner sidewalls of the front and rear sides of the dyeing pool via bearings, and corresponding to the outlet and inlet respectively;

[0007] The main body of the printing and dyeing device also includes a lifting frame and a lifting structure for driving the lifting frame to move up and down;

[0008] The lifting frame is located inside the dyeing tank and between two guide rollers. The lifting frame includes a base plate and two inverted U-shaped supports arranged symmetrically on the left and right. Each inverted U-shaped support includes a horizontal bar and two vertical bars. The two vertical bars are fixed to the top of the base plate and are arranged symmetrically front and back. The horizontal bar is fixed between the tops of the two vertical bars. The two dyeing rollers are respectively installed in the two inverted U-shaped supports. The dyeing rollers are rotatably connected between the two vertical bars through bearings and are located below the horizontal bar.

[0009] The lifting structure includes a horizontal plate, a vertical plate, a motor, and two pulling components. The horizontal plate is fixed to the rear outer wall of the dyeing tank, and the vertical plate is fixed to the top of the horizontal plate. Both pulling components are mounted on the vertical plate and arranged symmetrically on the left and right. Each pulling component is used to pull two inverted U-shaped supports. Each pulling component includes a drive shaft, a gear, a drive wheel, a driven shaft, a driven wheel, a winding roller, and a pull rope. The drive shaft is rotatably connected between the vertical plate and the rear outer wall of the dyeing tank via bearings. The gear and drive wheel are both fixedly sleeved on the drive shaft. Outside the shaft, one end of the passive shaft is rotatably connected to the vertical plate via a bearing. The driven wheel is fixedly sleeved outside the passive shaft and is connected to the driving wheel via a transmission belt. The winding roller is fixedly sleeved outside the passive shaft and above the corresponding horizontal bar. The pull rope is wound around the outside of the winding roller, one end of the pull rope is fixedly connected to the winding roller, and the other end of the pull rope passes into the dyeing pool and is fixedly connected to the horizontal bar. The gears in the two pulling components mesh with each other. The motor is mounted on the vertical plate to drive one of the driving shafts to rotate.

[0010] By adopting the above technical solution, when the fabric needs to be threaded, the motor is first started, and the output shaft of the motor rotates, driving one of the drive shafts to rotate. The drive shaft drives the gear and drive wheel to rotate. The drive wheel drives the driven wheel to rotate via a transmission belt. The driven wheel drives the passive shaft to rotate. The passive shaft drives the winding roller to rotate. Since the two pulling components are symmetrically arranged on the left and right, and the gears within them mesh with each other, the two gears rotate synchronously at the same speed and in opposite directions, thereby causing the two winding rollers to rotate synchronously at the same speed and in opposite directions. The two winding rollers simultaneously wind the pull ropes on them. The two pull ropes simultaneously pull the lifting frame upward until the dyeing roller is above the guide roller. At this time, the dyeing roller is removed from the dyeing agent and is close to the top opening of the dyeing tank. Then, the fabric is threaded into the dyeing tank through the feed port, and then sequentially passes above the right guide roller, below the right dyeing roller, below the left dyeing roller, and above the left guide roller, and then exits the dyeing tank through the discharge port and connects to the external winding structure. During the fabric threading process, workers do not need to reach deep into the dyeing vat or into the dyeing agent, making the process faster, more convenient, and more efficient. Once the fabric is threaded, the motor's output shaft rotates in reverse. Under the weight of the lifting frame itself, the frame moves downwards to its original position, and the pull rope unwinds from the winding roller. The lifting frame then moves the dyeing roller downwards to below the guide roller, thus tensioning the fabric.

[0011] This invention allows for faster and more convenient fabric threading, resulting in higher work efficiency.

[0012] A further feature of this invention is that sliders are fixed on the outer side walls of both the front and rear sides of the inverted U-shaped bracket, and a groove is provided on the inner side wall of the dyeing pool for the sliders to be inserted and slide up and down in a mating connection manner.

[0013] By adopting the above technical solution, when the inverted U-shaped bracket moves up and down, the slider moves up and down along the slide groove, thereby preventing the lifting frame from tilting during the up and down movement.

[0014] A further feature of this invention is that a spring is fixedly connected between the top end of the slider and the top wall of the groove.

[0015] By adopting the above technical solution, after the slider rises along the slide groove, the spring is pressed to generate a downward rebound force. When the motor's output shaft rotates in the opposite direction, the spring's rebound force, combined with the lifting frame's own weight, allows the lifting frame to descend more quickly.

[0016] A further feature of this invention is that the base plate has several through holes.

[0017] By adopting the above technical solution, the through-hole design can reduce the resistance of the dye to the base plate when the base plate moves up and down.

[0018] A further feature of this invention is that a fixing frame is fixed on the outer wall of the dyeing pool, and the end of the passive shaft facing away from the vertical plate is rotatably connected to the fixing frame via a bearing.

[0019] By adopting the above technical solution, the setting of the fixing frame can improve the stability of the passive shaft, thereby enhancing the stability of the winding roller.

[0020] A further feature of this invention is that a drain pipe is connected to the bottom of the outer wall of the dyeing pool, and a cover plate is placed on the top of the dyeing pool. The cover plate has openings on both the left and right sides for a pull rope to pass through.

[0021] By adopting the above technical solution, the setting of the drain pipe facilitates the discharge of dyeing agent from the dyeing tank; the setting of the cover plate can prevent dust from entering the dyeing tank; and the setting of the notch can prevent the cover plate from pressing and bending the pull rope, and ensure that the pull rope can move smoothly.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] A dyeing and printing device allows workers to put on fabric without having to reach deep into the dyeing pool or into the dyeing agent, making the process faster, more convenient, and more efficient. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] A dyeing and printing apparatus, such as Figures 1-3 As shown, the dyeing and printing apparatus includes the main body of the apparatus. The main body of the dyeing and printing apparatus includes a dyeing tank 1, a lifting frame, a lifting structure, and two guide rollers 2.

[0030] The dyeing tank 1 is a cylindrical structure with an open top, containing dyeing agent. Fixing brackets 3 are fixed to the outer walls on both the left and right sides of the dyeing tank 1. A drain pipe 4 is connected to the bottom of the outer wall of the dyeing tank 1. A cover plate 5 is fitted over the top of the dyeing tank 1. Openings 6 are provided on both the left and right sides of the cover plate 5. A discharge port 7 and a feed port 8 are respectively provided on the left and right sides of the dyeing tank 1. Vertically extending grooves 9 are provided on the inner walls of both the front and rear sides of the dyeing tank 1.

[0031] Both guide rollers 2 are rotatably connected between the inner walls of the front and rear sides of the dyeing pool 1 through bearings, and are located above the dye liquid surface, corresponding to the discharge port 7 and the inlet port 8 respectively.

[0032] The lifting frame is located inside the dyeing tank 1 and between two guide rollers 2. The lifting frame includes a base plate 10 and two inverted U-shaped supports symmetrically arranged on the left and right sides. Several through holes 11 are provided on the base plate 10. Each inverted U-shaped support includes a horizontal bar 12, a dyeing roller 13, and two vertical bars 14. Both vertical bars 14 are fixed to the top of the base plate 10 and are symmetrically arranged front and back. Each vertical bar 14 has a slider 15 fixed on it for inserting into a groove 9 and moving up and down along the groove 9. A spring 16 is fixedly connected between the top of the slider 15 and the top wall of the groove 9. The horizontal bar 12 is fixed between the tops of the two vertical bars 14. The dyeing roller 13 is rotatably connected between the two vertical bars 14 via bearings and is located below the horizontal bar 12.

[0033] The lifting structure includes a horizontal plate 17, a vertical plate 18, a motor 19, and two pulling components. The horizontal plate 17 is fixed to the rear outer wall of the dyeing tank 1. The vertical plate 18 is fixed to the top of the horizontal plate 17. Both pulling components are mounted on the vertical plate 18 and are symmetrically arranged on the left and right sides. The two pulling components are used to pull the two inverted U-shaped supports respectively. The pulling components include a drive shaft 20, a gear 21, a drive wheel 22, a driven shaft 23, a driven wheel 24, a winding roller 25, and a pull rope 26. The drive shaft 20 is rotatably connected between the vertical plate 18 and the rear outer wall of the dyeing tank 1 via bearings. The gear 21 and the drive wheel 22 are both fixedly sleeved on the outside of the drive shaft 20. The driven shaft 23 is rotatably connected between the vertical plate 18 and the fixed frame 3 via bearings. The driven wheel 24 is fixedly sleeved on the outside of the driven shaft 23 and is connected to the drive wheel 22 via a transmission belt. The winding roller 25 is fixedly sleeved on the outside of the passive shaft 23 and above the crossbar 12. The pull rope 26 is wound around the outside of the winding roller 25. One end of the pull rope 26 is fixedly connected to the winding roller 25, and the other end of the pull rope 26 passes through the notch 6 into the dyeing pool 1 and is fixedly connected to the crossbar 12.

[0034] The gears 21 in the two pulling components mesh with each other, and the motor 19 is mounted on the vertical plate 18 to drive the right drive shaft 20 to rotate.

[0035] Working principle:

[0036] When the fabric needs to be threaded, motor 19 is started first, and the output shaft of motor 19 rotates clockwise. This drives the right-side drive shaft 20 to rotate clockwise. The right-side drive shaft 20 drives the right-side gear 21 and drive wheel 22 to rotate clockwise. The right-side drive wheel 22 drives the right-side driven wheel 24 to rotate clockwise via a transmission belt. The right-side driven wheel 24 drives the right-side passive shaft 23 to rotate clockwise. The right-side passive shaft 23 drives the right-side winding roller 25 to rotate clockwise. Simultaneously, because the two pulling components are symmetrically arranged (i.e., the specifications of each gear 21, drive wheel 22, and driven wheel 24 are also the same), and the gears 21 are meshed, the left-side gear 21 rotates counterclockwise synchronously at the same speed. The left-side gear 21 drives the left-side drive shaft 20 to rotate counterclockwise. The left-side drive shaft 20 drives the left-side drive wheel 22 to rotate counterclockwise. The left-side drive wheel 22 drives the left-side driven wheel 24 to rotate counterclockwise. The driven wheel 24 on the left drives the driven shaft 23 on the left to rotate counterclockwise. The driven shaft 23 on the left drives the winding roller 25 on the left to rotate counterclockwise. This causes the pull rope 26 on both winding rollers 25 to wind around simultaneously. The two pull ropes 26 simultaneously pull the lifting frame upward until the dyeing roller 13 is above the guide roller 2. During the upward movement of the lifting frame, the slider 15 moves up and down along the slide groove 9, which can prevent the lifting frame from tilting during the up and down movement. And the spring 16 is pressed to form a downward rebound force.

[0037] At this point, the dyeing roller 13 is removed from the dyeing agent and positioned near the top opening of the dyeing tank 1. The fabric is then fed into the dyeing tank 1 through the inlet 8, and then sequentially passes above the right guide roller 2, below the right dyeing roller 13, below the left dyeing roller 13, and above the left guide roller 2. Finally, it exits the dyeing tank 1 through the outlet 7 and connects to the external winding structure. During the fabric feeding process, workers do not need to reach deep into the dyeing tank 1 or into the dyeing agent, making the feeding process faster, more convenient, and more efficient.

[0038] After the fabric is threaded through, the output shaft of motor 19 rotates in the opposite direction. Under the weight of the lifting frame itself and the rebound force of spring 16, the lifting frame moves downward and resets, and the pull rope 26 unfolds from the winding roller 25. The lifting frame drives the dyeing roller 13 to move downward to below the guide roller 2 and into the dyeing agent, thereby tensioning the fabric and immersing it in the dyeing agent.

[0039] This invention allows for faster and more convenient fabric threading, resulting in higher work efficiency.
