Description

[0001] The invention relates to the technical field of dye jiggers, in particular to a dye jigger mechanism of a high-temperature and high-pressure automatic dye jigger. Background Art

[0002] The high-temperature and high-pressure automatic dyeing machine is a cloth dyeing machine. The central mechanism is two cloth rollers that wind back and forth alternately. The fabric is unwound from one cloth roller and rolled onto another cloth roller. During the alternating winding process, the fabric continuously passes through the dye liquid under the cloth roller, absorbs the dye liquid onto the cloth surface, and adsorbs, combines, and fixes it during the winding process. When dyeing some dense fabrics, due to the high density of the fabric, the dye liquid penetration rate is not high and the speed is slow during the process of the fabric winding and passing through the dye liquid, which affects the efficiency of the equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The dyeing mechanism of the present invention can pressurize the dye liquid and spray it toward the cloth through the cooperation of the structures such as the flow balancing cavity tube, the beam flat mouth and the pressurized liquid pump. When dyeing some dense cloths, the impact force can be used to improve the penetration effect of the dye liquid, ensure sufficient dyeing, and improve the efficiency of the dyeing machine.

[0016] Through the coordination of the partition inner plate, movable gate plate and action electromagnet and other structures, the spray dye liquid of the beam flat mouth can be finely controlled in segmented switching. With the movement of the cloth under the beam flat mouth, the spray dye liquid can be targeted to impact and penetrate a certain part, thereby increasing the dyeing degree of the part and improving the functionality of the equipment.

[0017] Through the coordination of the pre-inserted positioning rod, the middle top plate and the synchronous shift plate and other structures, when the fixed cylinder cover and the shaft move to open and close the cylinder, all the movable gate plates can be forced to open once, so that the adhesion parts are separated, reducing the probability of the movable gate plates rusting and sticking due to long-term shutdown of the equipment, and the probability of the actuating electromagnet being difficult to attract the drive during later use.

[0018] Through the coordination of the structures such as the secondary lifting tongue, switching pressure piece and switching electromagnet, when the movable gate plates are all open for a long time, the secondary lifting tongue can be squeezed downward by the switching pressure piece, so that the secondary lifting tongue can squeeze and drive the middle top plate to move downward, and then the synchronous shifting plate can be deflected to shift the entire movable gate plate open; thereby avoiding the need to power all the action electromagnets to attract the movable gate plates to open, and greatly reducing the power consumption of the equipment.

[0036] like Fig.11 As shown in , the segmented control mechanism includes a partition inner plate 701, a movable gate plate 702 and a magnetic attraction action plate 703. The partition inner plate 701 is fixedly arranged inside the beam flat mouth 7. There are several groups of partition inner plates 701, and they are evenly distributed in a linear array along the length direction of the beam flat mouth 7.

[0037] A movable gate plate 702 is sealed and inserted between every two sets of partition inner plates 701 . One end of the movable gate plate 702 extends out of the beam flat port 7 and is fixedly mounted to the magnetic attraction action plate 703 .

[0038] The outer surface of the flow-equalizing cavity tube 6 is fixedly provided with a mounting eaves 704, on which an action electromagnet 705 is fixedly provided. There are several groups of action electromagnets 705, which correspond one to one with the magnetic action plates 703 respectively. After being energized, the action electromagnets 705 can be magnetically coordinated with the magnetic action plates 703. A reset spring bar 706 is provided between the outer surface of the magnetic action plate 703 and the beam flat mouth 7. The reset spring bar 706 applies an elastic force to the magnetic action plate 703 to move in the direction away from the action electromagnet 705.

[0039] A beam inner edge 707 is provided on the inner wall surface of the beam flat mouth 7, and a synchronous dial plate 708 is provided between the outer surface of the beam flat mouth 7 and the magnetic action plate 703. A dial plate shaft 709 is fixedly provided on the lower part of the synchronous dial plate 708.

[0040] A limited shaft seat 710 is fixedly provided on the outer surface of the beam flat mouth 7, and the dial plate shaft 709 is limitedly inserted through the limited shaft seat 710. A rotating pressure plate 711 is fixedly provided at the end of the dial plate shaft 709, and a reset pressure plate 712 is fixedly provided at the end of the rotating pressure plate 711.

An elastic pressure sheet 714 is provided in the C-shaped frame 713, and the elastic pressure sheet 714 applies downward elastic pressure to the reset pressure plate 712.

[0041] An intermediate top plate 715 is arranged above the rotating pressure plate 711, and a limiting sleeve 716 is fixedly arranged on the outside of the flow equalizing cavity tube 6. The intermediate top plate 715 is limited and inserted through the limiting sleeve 716, and a pre-inserted positioning rod 717 is fixedly arranged on the inner wall surface of the axially moving opening and closing cylinder 2, and an extrusion lower protrusion 718 is arranged at the lower part of the pre-inserted positioning rod 717, and a positioning matching sleeve 719 is fixedly arranged on the upper surface of the flow equalizing cavity tube 6; in the process of the axially moving opening and closing cylinder 2 moving toward the fixed cylinder cover 1 and gradually closing, the pre-inserted positioning rod 717 will first be inserted into the positioning matching sleeve 719, and then the extrusion lower protrusion 718 will pass through the upper end of the intermediate top plate 715; when the extrusion lower protrusion 718 passes through the upper end of the intermediate top plate 715, the intermediate top plate 715 will be extruded and driven downward, so that the intermediate top plate 715 moves downward to push the rotating pressure plate 711 to swing, thereby causing the dial plate shaft 709 to rotate.

[0042] A limiting groove 720 is provided through the pre-insertion positioning rod 717, in which a secondary lifting tongue 721 is inserted, and an inclined extrusion portion 722 is fixedly provided at the upper end of the secondary lifting tongue 721. When the shaft moves to open and close the closing cylinder 2 and the fixed cylinder cover 1, the secondary lifting tongue 721 is located directly above the middle top plate 715, and a tongue spring 723 is provided below the inclined extrusion portion 722.

[0043] A switching pressure piece 724 is disposed above the inclined extrusion portion 722, and a receiving portion 725 is provided at the lower portion of the switching pressure piece 724. An external frame plate 726 is fixedly disposed on the pre-insertion positioning rod 717, and a limiting slot plate 727 is fixedly disposed in the external frame plate 726. The switching pressure piece 724 is limitedly inserted through the limiting slot plate 727. Switching magnetic plates 728 are fixedly disposed at both ends of the switching pressure piece 724, and switching electromagnets 729 are fixedly disposed near the two sides of the internal portion of the external frame plate 726. After the switching electromagnets 729 are energized, they can be magnetically matched with the switching magnetic plates 728.

[0044] When the dye jigger mechanism of the present invention is in use, the fixed cylinder cover 1 is fixed to the automatic dye jigger, the axially movable opening and closing cylinder 2 is driven and installed with the automatic dye jigger, and the axially movable opening and closing cylinder 2 is controlled by the automatic dye jigger to realize the opening and closing control; Fig.10 and Fig.11 As shown in the figure, the fabric roll is installed on the fabric reel 3, and after passing around the guide pressure roller 4, it is wound up by another fabric reel 3. At this time, the fabric passes through the lower opening of the beam flat mouth 7; the dye liquid is added into the axis-moving closing cylinder 2, and the dye liquid level at least covers the flow balancing cavity tube 6.

[0045] During the dyeing process, the pressurized liquid pump 9 operates to absorb the dye solution through the suction pipe 10, pressurizes it into the flow supply pipe 8, and then enters the interior of the flow equalizing cavity tube 6 to be ejected from the beam flat port 7.

[0046] like Fig.11 As shown in the figure, after the action electromagnet 705 is powered off, the movable gate 702 is reset and closed under the elastic force of the reset spring bar 706. When the action electromagnet 705 is powered on, a magnetic force is generated, and the magnetic force is greater than the elastic force of the reset spring bar 706. The movable gate 702 is opened by attracting the magnetic action plate 703, so that the sprayed dye liquid of the beam flat mouth 7 can be finely controlled in sections. With the movement of the cloth under the beam flat mouth 7, the sprayed dye liquid can be targeted to penetrate a certain part, thereby increasing the dyeing degree of the part in a targeted manner and improving the functionality of the equipment.

[0047] In the process of the shaft moving the closing cylinder 2 toward the fixed cylinder head 1 and gradually closing; Figure 2 and Figure 3As shown in , the pre-inserted positioning rod 717 will first be inserted into the positioning matching sleeve 719 for limiting to prevent the end of the flow equalizing cavity tube 6 from sagging, and then the lower protrusion 718 will be squeezed to gradually move to the top of the middle top plate 715, squeezing and driving the middle top plate 715 to move downward, as shown in FIG. Figure 4 As shown in , the middle top plate 715 squeezes the rotating pressure plate 711. At this time, the rotating pressure plate 711 deflects, driving the dial plate shaft 709 to rotate a certain angle. The dial plate shaft 709 drives the synchronous dial plate 708 to rotate a certain angle. The synchronous dial plate 708 dials the entire magnetic action plate 703, so that the entire movable gate plate 702 is forced to open once; when the lower protrusion 718 is squeezed through the middle top plate 715, the middle top plate 715 moves up and resets, and the movable gate plate 702 is closed again. By forcibly driving all the movable gate plates 702 to open once, the adhesion parts are separated, reducing the probability that the movable gate plates 702 will rust and adhere due to long-term shutdown of the equipment, and the action electromagnet 705 will be difficult to attract and drive in later use.

[0048] When dense fabrics are dyed and there is no need to enhance the local dyeing degree of the fabrics, all movable gates 702 are controlled to open so that the beam flat mouth 7 sprays the dye liquid downward evenly in the shape of a water curtain, and the secondary beam through the beam inner edge 707 ensures that the dye liquid controlled in sections can be connected into a water curtain.

[0049] Under the above-mentioned working conditions where all the movable gates 702 need to be opened for a long time, Figure 3 As shown in , by supplying power to the switching electromagnet 729 on the corresponding side to attract the switching magnetic plate 728 to move, the switching pressure piece 724 moves along its own length direction, the accommodating portion 725 moves away from the top of the inclined plane extrusion portion 722, and the lower convex part of the switching pressure piece 724 squeezes the inclined plane extrusion portion 722, so that the inclined plane extrusion portion 722 and the secondary lifting tongue 721 move downward, and the secondary lifting tongue 721 pushes the middle top plate 715 downward to deflect the rotating pressure plate 711, drive the synchronous dial plate 708 to deflect, and open the movable gate plate 702. At this time, all the movable gate plates 702 are opened by the deflection of the synchronous dial plate 708. It avoids the method of supplying power to all the action electromagnets 705 to attract the movable gate plate 702 to open, which greatly reduces the power consumption of the equipment.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
