Description

Technical Field

[0001] The present application relates to the field of cloth dyeing equipment, and in particular to a dyeing machine with an automatic color adjustment function. Background Art

[0002] When dyeing cloth, if you want to dye the cloth into a specified color, you need to prepare a dye solution of corresponding concentration. A high or low concentration of the dye solution will cause the color of the dyed cloth to be darker or lighter.

[0003] Before dyeing the fabric, the operator needs to conduct a trial dyeing, that is, to pass the well-proportioned dye solution into the dyeing machine, and then put part of the fabric into the dyeing machine for dyeing to make a sample fabric. The color of the sample fabric is compared with the standard color card to determine whether the color of the sample fabric is qualified; if the color of the fabric does not meet the standard, dye or water is added and the trial dyeing is repeated until the color of the sample fabric reaches the standard, and then the fabric can be dyed in batches.

[0004] In the actual operation process, each dyeing of cloth takes a lot of time. After a piece of cloth is dyed, due to the consumption of dye and water, it is necessary to re-test and adjust before dyeing the next piece of cloth, which increases the time for dyeing batches of cloth and reduces the efficiency of cloth dyeing. Summary of the invention

[0005] In order to solve the problem of reduced dyeing efficiency of fabrics due to long trial dyeing time, the present application provides a dyeing machine with an automatic color adjustment function.

[0006] The present application provides a dyeing machine with automatic color adjustment function adopts the following technical solution:

[0007] A dyeing machine with an automatic color adjustment function comprises a dyeing machine body, a reflux pipe is arranged on the dyeing machine body, the end where dye liquid flows into the reflux pipe is defined as the starting end, and the end where dye liquid flows out of the reflux pipe is defined as the ending end, a detection mechanism for detecting the pH value and transmittance of the dye liquid, a feeding mechanism for adding materials such as dyes, and a water pump are sequentially distributed on the reflux pipe along the direction from the starting end to the ending end, and the detection mechanism is electrically connected to the feeding mechanism.

[0008] After the operator puts the prepared dye solution into the dyeing machine body, the dye solution is pumped into the reflux pipe, and the components in the dye solution are tested at the detection mechanism. The detection mechanism converts the test results into electrical signals and transmits them to the feeding mechanism. The feeding mechanism chooses to add water or other additives into the reflux pipe to adjust the dye solution to the specified concentration.

[0009] By adopting the above technical solution, the detection mechanism performs real-time detection of the dye concentration in the dyeing machine body, and the dye in the reflux pipe maintains continuous flow. Therefore, compared with manual sampling detection, the possibility of the concentration detection result being inconsistent with the actual concentration due to uneven mixing of the dye is reduced, and the reliability of concentration detection is effectively improved.

[0010] Optionally, the feeding mechanism includes an ultraviolet sensor and an acidity sensor arranged on the inner side wall of the reflux pipe; the feeding mechanism includes three feeding barrels, the feeding barrels are connected to the reflux pipe through the feeding pipe, and the feeding pipe is provided with an adjusting part for adjusting the amount of material added; the ultraviolet sensor and the acidity sensor are both electrically connected to the adjusting part.

[0011] By adopting the above technical solution, the three dye barrels are respectively filled with water, dye and acidity regulator. During the detection process, the transmittance of the dye liquid is detected by the ultraviolet sensor, and then the dye concentration in the corresponding dye liquid is compared. By adjusting the adjustment part connected with the water and the dye, water or dye is added to the dyeing machine body, so that the dye liquid concentration in the dyeing machine body reaches a suitable dyeing concentration; the acidity of the dye liquid is detected by the acidity sensor, and water or acidity regulator is added to the dyeing machine body by adjusting the adjustment part connected with the water and the acidity regulator, so that the acidity in the dyeing machine body reaches a suitable dyeing acidity;

[0012] It is also convenient to detect and replenish the dyeing liquid in real time during dyeing, which increases the probability of the dyed cloth appearing in the same color, thereby improving the quality of the dyed cloth; after a batch of cloth is dyed, water, dye and acidity regulator are added to the wastewater in the dyeing machine body until the dyeing liquid reaches the dyeing standard, which effectively saves water resources and reduces wastewater discharge.

[0013] Optionally, a mounting block is provided on the inner wall of the feeding tube, protruding toward the axis of the feeding tube, and a mounting groove is provided on the surface of the mounting block away from the axis of the feeding tube, and the depth direction of the mounting groove is perpendicular to the axis direction of the feeding tube. The adjusting member includes a motor and a flow regulating plate. The flow regulating plate is circular and coaxially rotatably installed in the feeding tube, and the arc-shaped side wall of the flow regulating plate is in contact with the inner wall of the feeding tube, the flow regulating plate and the mounting block are in contact with the side wall of the return pipe, a number of through holes of different apertures are provided on the flow regulating plate, and the mounting block blocks part of the through holes. The motor is installed in the mounting groove and is used to drive the flow regulating plate to rotate, and the ultraviolet sensor and the acidity sensor are both electrically connected to the motor.

[0014] By adopting the above technical solution, the liquid flows through the through holes with different apertures to achieve the effect of liquid addition speed. When the gap between the measured value and the set value is large, the motor drives the flow regulating plate to rotate, so that the liquid flows through the through hole with a larger aperture, so that the liquid is added at a faster speed, thereby improving the speed of dye liquid adjustment; when the gap between the measured value and the set value is small, the motor drives the flow regulating plate to rotate, so that the liquid flows through the through hole with a smaller aperture, so that the dye liquid is fine-tuned, thereby improving the accuracy of dye liquid adjustment;

[0015] The flow regulating plate is located on the side of the mounting block close to the return pipe, so that the mounting block hinders the flow of liquid, reduces the possibility of liquid flowing into the mounting groove from the rotating shaft of the flow regulating plate, and protects the motor. The mounting groove is in direct contact with the outside of the feeding pipe, which is convenient for replacement and maintenance of the motor.

[0016] Optionally, the return pipe portion between the head end of the return pipe and the detection mechanism is defined as a filter tube, a filter net is arranged inside the filter tube, the filter tube and the return pipe are detachably installed, a connecting tube is rotatably installed at the end of the return pipe close to the filter tube, one end of the connecting tube away from the return pipe is threadedly connected to the end of the filter tube, and the installation position of the connecting tube is limited by a positioning mechanism.

[0017] By adopting the above technical solution, the lint on the fabric is filtered before the dye solution is tested, which reduces the influence of the lint on the test results during the test process, especially the test of transmittance, so that the test results are closer to the actual data, thereby increasing the possibility of the fabric reaching the specified color; compared with directly replacing the filter in the tube, the detachable setting of the filter tube makes replacing the filter more convenient and quick.

[0018] Optionally, the positioning mechanism includes a first retaining ring protruding from the outer wall of the end of the return pipe, a second retaining ring protruding from the inner wall of the end of the connecting tube away from the filter tube, and an anti-loosening member installed on the outer wall of the return pipe, the return pipe is slidably passed through the first retaining ring, the second retaining ring is rotatably engaged in the connecting tube, the anti-loosening member is located between the first retaining ring and the second retaining ring, and the anti-loosening member is respectively abutted against the first retaining ring and the second retaining ring.

[0019] By adopting the above technical solution, the second retaining ring and the first retaining ring are abutted by the anti-loosening member, thereby increasing the friction of the threads between the connecting tube and the filter tube, effectively hindering the relative rotation between the connecting tube and the filter tube after installation, thereby improving the reliability of the connection installation; and after disassembling the filter tube, the connecting tube can be sleeved on the return pipe, and the first retaining ring and the second retaining ring hinder the possibility of the connecting tube being lost due to slipping, thereby improving the efficiency of the filter tube installation.

[0020] Optionally, the first retaining ring has a plurality of sliding holes distributed along the circumference of the first retaining ring on the side wall facing the second retaining ring, the depth direction of the sliding holes is parallel to the thickness direction of the first retaining ring, the anti-loosening component includes a sliding rod installed in the sliding hole along the depth direction of the sliding hole, a back plate is provided at one end of the sliding rod away from the first retaining ring, the back plate abuts against the second retaining ring, a first spring is sleeved on the sliding rod, and two ends of the first spring are respectively connected to the first retaining ring and the back plate.

[0021] By adopting the above technical solution, a plurality of circumferentially distributed first springs form an abutment against the first baffle plate and the second baffle plate. Since the first baffle ring is protrudingly arranged on the outer wall of the return pipe, if a spring washer is used, it is inconvenient to install a new spring washer when the spring washer fails. The first spring pushes the abutment plate to abut against the first baffle ring, which not only has an abutment effect but also facilitates the replacement of the first spring.

[0022] Optionally, a semicircular groove is provided on the side wall of the abutment plate away from the slide rod along the radial direction of the second retaining ring, a cylindrical roller is rotatably installed in the semicircular groove, and the rotation axis of the roller is parallel to the length direction of the semicircular groove, and the roller abuts against the first retaining ring.

[0023] By adopting the above technical solution, when installing the filter tube, the filter tube is first aligned with the return pipe, and then the connecting tube is rotated to move toward the filter tube under the action of the thread, and the first spring is continuously compressed. By replacing the sliding friction with the rolling friction, the friction resistance of the connecting tube during screwing is reduced, the friction loss is reduced, and the service life of the base plate is increased.

[0024] The filter element is provided with a groove on the end wall of the filter tube near the head end of the return tube, the groove extends along the length direction of the filter tube, and a filter cartridge is slidably installed in the groove along the depth direction of the groove, and the filter screen is installed in the end of the filter cartridge near the bottom of the groove of the groove, and the side wall of the groove is provided with a clamping groove, and the clamping groove extends along the radial direction of the groove, and a clamping block is slidably installed in the clamping groove, and the cross-section of the clamping block is a ninety-degree sector-shaped, and two radial sides of the sector are respectively parallel and perpendicular to the axis of the slide slot, and the arc of the sector is located on the side of the radial side perpendicular to the axis of the slide slot close to the groove opening of the slide slot, and a guide block is provided at the end of the block away from the bottom wall of the clamping groove, and the guide block is an eighth of a sphere, and the planar side wall contour of the guide block is in fits with the end wall contour of the clamping block, and a square recessed hole clamped with the guide block is provided on the outer wall of the filter cartridge.

[0025] By adopting the above technical solution, when installing the filter cartridge, the guide block is pressed into the snap-in groove under the action of the arc-shaped side wall of the guide block. When the filter cartridge moves to the specified position, the guide block is pushed into the square recessed hole and a snap connection is formed between the guide block and the side wall of the square recessed hole along the axial direction of the filter cartridge; when disassembling the filter cartridge, first rotate the filter cartridge to press the guide block into the snap-in groove, and then pull out the filter cartridge to complete the disassembly; disassembly and installation of the filter cartridge by sliding and rotating is more convenient and quick.

[0026] Optionally, a placement groove is opened on the inner side wall of the filter cartridge along the length direction of the filter cartridge, and a pull rod is rotatably installed in the placement groove through a torsion spring, and the rotation axis of the pull rod is parallel to the width direction of the placement groove. Under the action of the torsion spring, the pull rod is received in the placement groove, and a clamping groove is opened on the inner side wall of the filter cartridge away from the placement groove, and one end of the pull rod away from the torsion spring is rotatably clamped in the clamping groove.

[0027] By adopting the above technical solution, when disassembling the filter cartridge, one end of the pull rod is rotated and connected to the slot, which makes it convenient for the operator to apply force to rotate and pull out the filter cartridge, thereby improving the efficiency of disassembling the filter cartridge. After the filter cartridge is installed, the pull rod is stored in the placement slot, which reduces the accumulation of hair debris at the pull rod and reduces the ability of the filter cartridge to temporarily store hair debris.

[0028] Optionally, a protrusion with a semicircular cross-section is protruded from the side wall of the pull rod away from the bottom of the placement groove, the axis of the protrusion is perpendicular to the length direction of the pull rod, the side wall of the slot close to the filter net is an inclined guide slope, and the guide slope gradually moves away from the filter net along the depth direction of the slot.

[0029] By adopting the above technical solution, the protrusion with a semicircular cross-section makes it easy for the operator to lift the pull rod, while preventing hair debris from accumulating at the installation protrusion. The hair debris flows to the filter under the guidance of the guiding slope, making it difficult for the hair debris to block the slot, thereby facilitating the pull rod to be inserted into the slot.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

The section of the return pipe 12 between the head end of the return pipe 12 and the detection mechanism 2 is defined as a filter tube 4, and both ends of the filter tube 4 are connected to the return pipe 12 through a connecting tube 41, wherein one end of the connecting tube 41 is sleeved and slidably installed on the return pipe 12, and the connecting tube 41 is rotatably matched with the return pipe 12, and the other end of the connecting tube 41 is sleeved on the filter tube 4 and threadedly connected to the filter tube 4, and the connecting tube 41 is positioned and installed by a positioning mechanism 5.

[0046] Reference Figure 2 and Figure 3 The positioning mechanism 5 includes a first retaining ring 51, a second retaining ring 52 and a locking member 53. The first retaining ring 51 is protrudingly arranged on the outer side wall of the end of the return pipe 12.
