Description

Technical Field

[0001] This utility model relates to the technical field of dyeing machines, and more specifically to a front-mounted dual mist nozzle structure for a dyeing machine. Background Technology

[0002] A dyeing machine is a device specifically designed for dyeing textiles. Its working principle involves mechanical stirring and chemical action to ensure the fibers are evenly dyed in the dye bath. Existing dyeing machines consist of components such as a cylinder, fabric trough, conveying pipes, fabric lifting wheels, a fan, and a fabric positioning mechanism. A front nozzle is installed on the conveying pipe in front of the fabric lifting wheels, and a rear nozzle is installed on the conveying pipe behind them. Regarding the front nozzle, there are currently two types of gas-liquid machines on the market: one is overflow + atomization. With this type of nozzle, overflow or atomization is only suitable for use alone. When using atomization, the flow rate is too low, while using overflow results in an awkward situation of too high a flow rate. This limits its application to different fabrics and can easily lead to quality problems. The other type is single overflow, which moves the atomization structure to the rear nozzle. However, the interaction time between the rear atomizer and the fabric is short, which can also cause quality problems with different fabrics. Therefore, to expand the applicable range of fabrics and improve fabric quality, the design of the front nozzle needs to be optimized. Utility Model Content

[0020] Example: See Figures 1 to 3 As shown, a front-mounted dual-mist nozzle structure for a dyeing machine includes a cylinder 1, a fabric trough 2, a fabric lifting wheel mechanism 3, a fan 4, and a fabric swaying mechanism 5. The fabric trough 2 is located inside the cylinder 1. The fabric lifting wheel mechanism 3 is located above the cylinder 1 and is connected to the front and rear ends of the upper part of the cylinder 1 through a front conveying pipe and a rear conveying pipe, respectively. The fabric swaying mechanism 5 is located at the outlet of the rear conveying pipe, and a fabric lifting interface 6 is provided at the inlet of the front conveying pipe. The characteristic feature is that an annular partition 61 is provided inside the fabric lifting interface 6, and the partition 61 separates the upper annular cavity a and the lower annular cavity b of the fabric lifting interface 6, which are distributed vertically.

[0021] The upper ring cavity a of the fabric interface 6 is provided with several annularly distributed upper atomizing nozzles 8, and the lower ring cavity b is provided with several annularly distributed lower atomizing nozzles 9; the dyeing machine is equipped with multiple sets of dye liquor conveying pipelines, and the upper atomizing nozzles 8 and lower atomizing nozzles 9 are respectively connected to different dye liquor conveying pipelines and can work independently.

[0022] The upper front part of the cylinder 1 is provided with an inlet / outlet window, and a working door 7 is provided on the inlet / outlet window. The fabric lifting interface 6 is located above the working door 7. The dyed fabric can enter the cylinder 1 after the working door 7 is opened. The working door 7 is closed when dyeing and opened when taking out the fabric.

[0023] The upper atomizing nozzle 8 and the lower atomizing nozzle 9 are both inclined upwards, and the nozzles of the upper atomizing nozzle 8 and the lower atomizing nozzle 9 are both facing the center of the fabric lifting interface 6.

[0024] The upper atomizing nozzle 8 has 4 to 6 units, and the lower atomizing nozzle 9 has 4 to 6 units. The upper atomizing nozzle 8 and the lower atomizing nozzle 9 are evenly distributed in a ring around the central axis of the fabric lifting interface 6. The number of units in one group of upper atomizing nozzle 8 and lower atomizing nozzle 9 is greater than the number of units in the other group, that is, the atomization flow rate of one group is greater than the atomization flow rate of the other. For example, the upper atomizing nozzle 8 can be set to 4 units, and the lower atomizing nozzle 9 can be set to 6 units. At the same time, the diameter of the lower atomizing nozzle 9 is larger than the diameter of the upper atomizing nozzle 8.

[0025] A horizontally annular mounting plate 11 is fixedly connected to the upper annular cavity a and the lower annular cavity b of the fabric-lifting interface 6, respectively. The inner ring of the mounting plate 11 is formed with several inclined downward support plates 111. The lower end of the support plate 111 is formed with a spherical angle adjustment seat 112. A spherical adjustment head 10 is embedded in the angle adjustment seat 112. The lower atomizing nozzle 9 or the upper atomizing nozzle 8 is respectively inserted and fixed in the adjustment head 10. The bottom of the angle adjustment seat 112 is formed with an opening 113. The connector on the lower atomizing nozzle 9 or the upper atomizing nozzle 8 passes through the opening 113 and is fitted with a spherical connecting block 12. The connector extends out of the connecting block 12 and is screwed with a locking nut 13. The connecting block 12 is clamped and fixed between the locking nut 13 and the angle adjustment seat 112. The above structure is specifically fixed to the lower atomizing nozzle 9 or the upper atomizing nozzle 8. Its advantage is that the installation angle of the lower atomizing nozzle 9 or the upper atomizing nozzle 8 can be adjusted.

[0026] The adjusting head 10 is formed with stepped holes that penetrate the two opposite outer walls of the adjusting head 10, and the lower atomizing nozzle 9 or the upper atomizing nozzle 8 is respectively inserted into the stepped holes of the adjusting head 10.

[0027] The diameter of the connector on the lower atomizing nozzle 9 or the upper atomizing nozzle 8 is smaller than the diameter of the opening 113 on the angle adjusting seat 112.

[0028] An inclined stiffener 14 is fixedly connected to the support plate 111. The upper and lower ends of the stiffener 14 are fixedly connected to the mounting plate 11 and the angle adjustment seat 112, respectively. The radius of the inner wall of the angle adjustment seat 112 is equal to the radius of the outer wall of the adjustment head 10.

[0029] Working principle: This structure is a front-mounted dual-atom nozzle structure on a dyeing machine. The front-mounted dual-atom nozzle structure consists of an upper atomizing nozzle 8 and a lower atomizing nozzle 9. The two sets of atomizing nozzles produce different atomization flow rates, and the upper atomizing nozzle 8 and the lower atomizing nozzle 9 can be opened independently, that is, there are three situations: the first is that the upper atomizing nozzle 8 is open and the lower atomizing nozzle 9 is not open; the second is that the upper atomizing nozzle 8 is not open and the lower atomizing nozzle 9 is open; the third is that the upper atomizing nozzle 8 and the lower atomizing nozzle 9 are open at the same time.

[0030] Therefore, when the fabric requires a small flow rate of atomization, only the set of atomizing nozzles with a smaller atomization flow rate needs to be turned on; when the fabric requires a medium flow rate of atomization, only the set of atomizing nozzles with a larger atomization flow rate needs to be turned on; and when the fabric requires a large flow rate of atomization, both sets of atomizing nozzles need to be turned on.

[0031] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
