Description

Technical Field

[0001] This application relates to the field of fabric printing and dyeing, and particularly to an overflow dyeing machine. Background Art

[0002] Overflow dyeing machines are mainly used for the treatment and dyeing of various knitted grey fabrics such as pure cotton, pure polyester, polyester-cotton, and spandex.

[0003] Currently, the Chinese utility model with the authorization announcement number CN204111006U discloses a fabric discharging mechanism for a dyeing vat, including a main bracket, a fabric distributing mechanism, and a fabric feeding mechanism. The fabric feeding mechanism and the fabric distributing mechanism are sequentially arranged on the main bracket along the fabric conveying direction. The fabric feeding mechanism includes a support plate, a fabric feeding roller, a fabric sending roller, and a fabric pressing mechanism. The fabric sending roller is horizontally rotatably connected to the upper side of the main bracket, and a fabric sending motor is arranged at one end of the fabric sending roller. The fabric pressing mechanism includes a fabric pressing bracket and a fabric pressing roller. The fabric distributing mechanism includes a fabric distributing wheel, a fabric distributing rod, a fabric distributing plate, a fabric guiding roller, and a connecting shaft. The fabric distributing wheel is rotatably connected to one side of the main bracket, the fabric distributing plate is hingedly connected to the main bracket, the connecting shaft is horizontally arranged between two fabric distributing plates, a plurality of mounting holes are arranged along the diameter direction on the fabric distributing wheel, and a fabric discharging hopper is horizontally arranged at the lower end of the fabric distributing plate.

[0004] When discharging the fabric, first take out the fabric head from the overflow dyeing machine, and then pass it through the fabric pressing mechanism and the fabric distributing mechanism for blanking. The fabric pressing mechanism presses the fabric, and the water on the fabric will flow to the ground. At the same time, when the fabric is taken out from the overflow dyeing machine to the fabric pressing mechanism, the dye carried on the fabric will drip on the ground, which not only causes loss of dye but also has certain harm to the environment. Utility Model Content

[0005] In order to reduce the dye dripping onto the ground when the fabric is taken out from the overflow dyeing machine, this application provides an overflow dyeing machine.

[0006] An overflow dyeing machine provided by this application adopts the following technical solution: An overflow dyeing machine includes a dyeing machine main body and a frame. A horizontal upper roller and a lower roller are rotatably connected to the frame. The upper roller and the lower roller are both arranged perpendicular to the fabric conveying direction. An extrusion opening for the fabric to pass through and for squeezing the fabric is formed between the upper roller and the lower roller. A water tank is arranged on the frame, and the water tank is located directly below the extrusion opening.

[0007] By adopting the above technical solution, the fabric taken out from the overflow dyeing machine first passes through the extrusion opening between the upper roller and the lower roller, so that part of the dye on the fabric is squeezed out. The squeezed-out dye is collected through the water tank arranged below the extrusion opening, playing a role in recycling the dye.

[0008] Optionally, a water retaining tank is provided on the frame. Both the upper roller and the lower roller are located inside the water retaining tank. An inlet and an outlet for the fabric to enter and exit are respectively formed at both ends of the water retaining tank along the fabric conveying direction. A drain pipe connected to the water tank is provided at the bottom of the water retaining tank.

[0009] During the process of the upper roller and the lower roller squeezing the fabric, the upper roller and the lower roller rotate, causing the dye to splash, which is likely to cause pollution. By adopting the above technical solution, the upper roller and the lower roller are arranged in the water retaining tank, and the splashed dye is blocked by the water retaining tank, reducing pollution. The dye accumulated in the water retaining tank flows into the water tank through the drain pipe for collection.

[0010] Optionally, two first sliding rods are slidably connected to the frame in the vertical direction. A first driving member for driving the first sliding rods to slide in the vertical direction is provided on the frame. The two first sliding rods penetrate the bottom surface of the water retaining tank upward in the vertical direction and extend into the interior of the water retaining tank. Both ends of the upper roller and the lower roller are respectively rotatably connected to the two first sliding rods.

[0011] When facing a dyeing machine main body of a certain size, it is necessary to adjust the positions of the upper roller and the lower roller so that the extrusion port matches the fabric outlet of the dyeing machine main body. By adopting the above technical solution, the operator controls the first driving member to drive the first sliding rods to move up and down in the vertical direction, and the first sliding rods drive the upper roller and the lower roller to move up and down in the water retaining tank to the required positions.

[0012] Optionally, the first driving member includes a motor, a first worm, and a first worm gear. The first worm gear is rotatably connected to the frame. The first worm gear is sleeved on the first sliding rod and is in threaded cooperation with the first sliding rod. The first worm is coaxially connected to the transmission shaft of the motor, and the first worm meshes with the first worm gear.

[0013] By adopting the above technical solution, the motor operates to drive the first worm to rotate. The first worm meshes with the first worm gear to drive the first worm gear to rotate. When the first worm gear rotates, it drives the first sliding rod to move up and down through the threaded cooperation with the first sliding rod.

[0014] Optionally, a vertical sliding groove is formed on the first sliding rod. The sliding groove penetrates the first sliding rod along the axial direction of the upper roller. The rotating shaft of the upper roller is slidably connected in the sliding groove in the vertical direction. A horizontal fixing rod is provided on the first sliding rod. A second sliding rod is slidably arranged on the fixing rod in the vertical direction. A second driving member for driving the second sliding rod to slide up and down is provided on the second sliding rod. The lower end of the second sliding rod is rotatably connected to the upper roller through a connecting member.

[0015] When facing fabrics of different materials, it is necessary to adjust the size of the extrusion opening between the upper roller and the lower roller to obtain a better effect of squeezing out water. By adopting the above technical solution, the operator controls the second driving member provided on the fixed rod to drive the second sliding rod to move up and down in the vertical direction. The second sliding rod drives the connecting member to move up and down, and the second connecting member drives the upper roller to move up and down, thereby adjusting the size of the extrusion opening.

[0016] Optionally, the second driving member includes a second worm gear and a second worm. The second worm gear is rotatably connected to the fixed rod. The second worm gear is sleeved on the second sliding rod and is in threaded cooperation with the second sliding rod. The second worm is rotatably connected to the fixed rod and meshes with the second worm gear. One end of the second worm is coaxially connected with a handle.

[0017] By adopting the above technical solution, the operator rotates the handle. The handle drives the second worm to rotate. The second worm meshes with the second worm gear to drive the second worm gear to rotate. When the second worm gear rotates, it drives the second sliding rod to move up and down through threaded cooperation with the second sliding rod.

[0018] Optionally, the connecting member includes a first semi-circular block and a second semi-circular block. One end of each of the first semi-circular block and the second semi-circular block is rotatably connected to the lower end of the second sliding rod. An elastic rope is provided on the inner ring surface of the first semi-circular block. A spherical ball is provided at one end of the elastic rope away from the first semi-circular block. A long strip-shaped groove is formed on the ring surface of the second semi-circular block along the ring surface of the second semi-circular block. The long strip-shaped groove penetrates through the second semi-circular block. A circular groove penetrating through the second semi-circular block is formed on the ring surface of the second semi-circular block. The circular groove is located in the middle of the long strip-shaped groove. The size of the circular groove is greater than or equal to the cross-sectional size of the spherical ball. The width of the long strip-shaped groove is greater than or equal to the width of the elastic rope and less than the diameter of the spherical ball. Saw teeth are provided on the inner side wall of the long strip-shaped groove. A clamping block for clamping with the saw teeth is provided at the connection between the spherical ball and the elastic rope.

[0019] By adopting the above technical solution, the operator stretches the elastic rope, passes the spherical ball through the second semi-circular block from the circular groove, and then slides down along the long strip-shaped groove after passing through. After releasing the hand, the elastic rope retracts, and the spherical ball clamps the second semi-circular block so that the first semi-circular block and the second semi-circular block form a ring and are connected to the upper roller. The clamping block clamps the rack to prevent the spherical ball from detaching from the second semi-circular block due to the vibration of the equipment during operation.

[0020] Optionally, limit blocks are provided at the ends of the rotating shafts of the upper roller away from each other.

[0021] By adopting the above technical solution, the limit blocks are used for clamping with the mounting member to prevent the upper roller from disengaging from the connecting member due to deviation during rotation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Excess dye is squeezed out of the fabric through the extrusion opening between the upper roller and the roller.

[0024] 2. The positions of the upper roller and the lower roller in the vertical direction are adjusted by the first driving member to adapt to dyeing machine bodies of different sizes.

[0025] 3. The size of the extrusion opening between the upper roller and the lower roller is adjusted by the second driving member to adapt to fabrics of different materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following further describes the present application in detail with reference to the attached Figures 1-6 drawings.

[0034] An embodiment of the present application discloses an overflow dyeing machine. Refer to Figure 1, An overflow dyeing machine includes a dyeing machine main body 1 and a frame 4 provided on one side of the dyeing machine main body 1. A water retaining tank 2 is installed on the frame 4. The water retaining tank 2 is located in the direction of the fabric outlet of the dyeing machine main body 1. An inlet and an outlet for the fabric to pass through are respectively provided at both ends of the water retaining tank 2 along the fabric outlet direction. A water tank 3 is installed below the water retaining tank 2. A drain pipe 5 is connected to the bottom surface of the water retaining tank 2. The drain pipe 5 extends into the water tank 3 to drain the dye in the water retaining tank 2 into the water tank 3.

[0035] Refer to Figure 1 and Figure 2 , Two vertical first sliding rods 8 are slidably connected to the frame 4 in the vertical direction. Both of the two first sliding rods 8 pass upward through the bottom surface of the water retaining tank 2 and extend into the water retaining tank 2. A first driving member for adjusting and positioning the up and down positions of the first sliding rods 8 is provided on the frame 4. A lower roller 92 is rotatably connected to the first sliding rods 8. Both ends of the lower roller 92 are respectively rotatably connected to the two first sliding rods 8. A vertical sliding groove 18 is provided on the first sliding rods 8. The sliding groove 18 is located above the lower roller 10. The sliding groove 18 penetrates the first sliding rods 8 along the axial direction of the lower roller 92. A horizontal upper roller 91 is slidably connected in the sliding groove 18 in the vertical direction. The rotating shafts at both ends of the upper roller 91 are respectively slidably connected in the two sliding grooves 18 in the vertical direction. A horizontal fixing rod 19 is fixed to one end of the first sliding rod 8 away from the lower roller 92. A second sliding rod 11 is slidably connected to the fixing rod 19 in the vertical direction. A second driving member for driving the second sliding rod 11 to move up and down is provided on the second sliding rod 11. The lower end of the second sliding rod 11 is connected to the rotating shaft of the upper roller 91 through a connecting member 15. Limit blocks 14 are fixedly connected to both ends of the rotating shaft of the upper roller 91. The limit blocks 14 are located on the side of the connecting member 15 away from the second sliding rod 11. The limit blocks 14 prevent the upper roller 91 from sliding out of the connecting member 15. An extrusion opening for the fabric to pass through and squeeze out excess dye is formed between the upper roller 91 and the lower roller 92.

[0036] Refer to Figure 3 , The first driving member includes a motor 6, a first worm 7, and a first worm gear 20. The motor 6 is installed on the frame 4. The transmission shaft of the motor 6 is coaxially connected to the first worm 7. The first worm 7 meshes with the first worm gear 20. The first worm gear 20 is rotatably connected to the frame 4. The first worm gear 20 is sleeved on the first sliding rod 8 and is in threaded cooperation with the first sliding rod 8. When the motor 6 works, it drives the first worm 7 to rotate. The first worm 7 drives the first worm gear 20 to rotate. The rotation of the first worm gear 20 causes the first sliding rod 8 to move up and down. When the first sliding rod 8 moves up and down, it drives the extrusion opening to move up and down, so that when facing dyeing machine main bodies 1 of different sizes, the position of the extrusion opening is more matched with the fabric outlet of the dyeing machine main body 1.

[0037] Refer to Figure 4, the second driving member includes a second worm gear 16, a second worm 12 and a handle 13. The second worm gear 16 is rotatably connected to the fixed rod 19. The second worm gear 16 is sleeved on the second sliding rod 11 and is in threaded cooperation with the second sliding rod 11. The second worm 12 is inserted and connected to the fixed rod 19 and meshes with the second worm gear 16. One end of the second worm 12 is rotatably connected with a handle 13. Rotating the handle 13 drives the second worm 12 to rotate. The second worm 12 drives the second worm gear 16 to rotate. The rotation of the second worm gear 16 causes the second sliding rod 11 to move up and down.

[0038] Refer to Figure 5 and Figure 6 , the connecting member 15 includes a first semi-circular block 151 and a second semi-circular block 152. When the first semi-circular block 151 and the second semi-circular block 152 are closed, a circular space is formed outside the rotating shaft of the upper roller 9. An elastic rope 153 is connected to the inner circular surface of the first semi-circular block 151. One end of the elastic rope 153 away from the first semi-circular block 151 is connected with a spherical ball 154. A clamping block 155 is fixed at the connection of the spherical ball 154 and the elastic rope 153. A long strip-shaped groove 157 penetrating the second semi-circular block 152 is formed along the length direction of the second semi-circular block 152 on the circumferential surface of the second semi-circular block 152. A circular groove 158 penetrating the second semi-circular block is formed on the circumferential surface of the second semi-circular block 152. The circular groove 158 is located in the middle of the long strip-shaped groove 157. The size of the circular groove 158 is greater than or equal to the cross-sectional size of the spherical ball 154 so that the spherical ball 154 can pass through the circular groove 158. Saw teeth 156 are fixed on the inner wall of the long strip-shaped groove 157. The width size of the long strip-shaped groove 157 is smaller than the diameter size of the spherical ball 154 and larger than the diameter size of the elastic rope 153 and smaller than the diameter size of the spherical ball 154, so that the long strip-shaped groove 157 can clamp the spherical ball 154 to close the first semi-circular block 151 and the second semi-circular block 152. The clamping block 155 is used to form a clamping connection with the saw teeth 156 to reduce the possibility of the spherical ball 154 moving in the long strip-shaped groove 157, so that the first semi-circular block 151 and the second semi-circular block 152 can maintain a locked state. When the spherical ball 154 clamps the second semi-circular block 152, the elastic rope 153 is located on the side of the center of the first semi-circular block 151 away from the second semi-circular block 152.

[0039] The implementation principle of an embodiment of the present application is as follows: When the fabric is taken out from the fabric outlet of the dyeing machine main body 1, it enters the extrusion opening between the upper roller 91 and the lower roller 92 through the inlet of the water baffle tank 2, so that the fabric is squeezed to remove excessive dye. The dye flows into the water tank 3 through the drain pipe 5 at the bottom of the water baffle tank 2 for collection.

[0040] When facing overflow dyeing machines of different sizes, the operator controls the motor 6 to drive the first worm 7 to rotate. The first worm 7 drives the first worm gear 20 to rotate, and the first worm gear 20 drives the first sliding rod 8 to move up and down. The first sliding rod 8 drives the upper roller 9 and the lower roller 10 to move to the required positions.

[0041] When facing fabrics of different materials, the operator rotates the handle 13 to drive the second worm 12 to rotate. The second worm 12 drives the second worm gear 16 to rotate, and the second worm gear 16 drives the second sliding rod 11 to move up and down. The first sliding rod 8 drives the upper roller 9 to move so that the size of the extrusion opening between the upper roller 9 and the lower roller 10 meets the requirements of the operator.

[0042] The setting of the connecting piece 15 facilitates the disassembly and installation of the upper roller 9. The operator passes the spherical ball 154 through the circular groove 158 and then moves the spherical ball 154 downward along the elongated groove 157 so that the spherical ball 154 clamps the second semi-circular block 152, thereby closing the first semi-circular block 151 and the second semi-circular block 152 into a ring and sleeving it on the rotating shaft of the upper roller 9 to complete the installation of the upper roller 9.

[0043] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
