Description

Technical Field

[0001] The present application relates to the technical field of dyeing machines, and in particular to a dyeing machine with adjustable running water flow. Background Art

[0002] Dyeing machines are one of the most important equipment in the field of textile processing, used to dye fabrics to meet the needs of various clothing, home furnishings, decorations, etc. In the development of dyeing machines, improving the efficiency, uniformity and quality of dyeing has always been an important research direction.

[0003] In traditional dyeing machines, usually only one front sump is set up to extract the dye liquid in the dye drum and send it to the tail of the dye drum together with the cloth to form a cycle. However, there are some problems with this design. First, since there is only one sump, the extraction and supply speed of the dye liquid is limited, resulting in the inability to accurately control the running speed of the cloth, thus affecting the uniformity and quality of dyeing. Secondly, since the flow rate of the dye liquid cannot be accurately controlled, the dyeing effect of the cloth may also be inconsistent, especially in the dyeing process of large volume and low bath ratio, this problem is more prominent.

[0004] In order to solve the above problems, a Chinese patent with the authorization announcement number CN 219117748 U discloses an ultra-large capacity low bath ratio dyeing machine. The dyeing machine is provided with two front and rear water collection tanks, and two flow regulating valves are connected to the front and rear water collection tanks respectively, so that the water flow rate of the front and rear water collection tanks can be controlled, and then the speed of the water flow in the dyeing drum can be controlled. Through this design, the running speed of the cloth can be more accurately regulated, and the uniformity and quality of dyeing can be improved.

[0005] However, although the design of the above-mentioned dyeing machine has improved the control accuracy of the dyeing effect to a certain extent, the control method using only two flow regulating valves still has certain limitations. First, the control method of the two flow regulating valves is relatively simple and cannot achieve further fine adjustment of the water flow rate. Secondly, due to changes in factors such as the thickness, density and properties of the dyeing liquid during the dyeing process, the water flow rate needs to be adjusted in real time to maintain the best dyeing effect, and the control method of the two flow regulating valves may not be able to meet this real-time adjustment demand.

[0006] Therefore, in order to further improve the control accuracy and flexibility of the water flow speed in the dyeing machine, it is necessary to develop more sophisticated control methods to optimize the cloth dyeing process and improve the dyeing quality. Utility Model Content

[0014] In one of the embodiments: a flow-blocking baffle is provided between the water flow regulating valve and the inclined mesh plate, the projection of the flow-blocking baffle in the direction perpendicular to the inclined mesh plate covers the water flow regulating valve but does not cover the rear water collecting tank, and the flow-blocking baffle is arranged to be tilted downward from the tail to the nose of the machine, and the inclination amplitude is greater than the inclined mesh plate.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] In the description of the present application, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0031] Embodiment 1: A dyeing machine with adjustable running water flow, such as Figure 1 As shown, the dyeing drum 100 includes a screen plate, a front water collecting tank 130 and a rear water collecting tank 140. The dyeing drum 100 is divided into three parts from the beginning to the end: a head 110, a drum body 120 and a tail. Figure 1 The tail section is not shown.

[0032] The screen is located in the dyeing drum 100 , and the cross section of the screen is in a straight line or a flared U shape, wherein the flared U shape is opened upward.

[0033] The screen plates inside the body 120 of the dye drum 100 include at least one lower screen plate and one inclined screen plate 210. The inclined screen plate 210 is inclined downward from the tail of the dye drum 100 toward the body 120. When there are multiple inclined screen plates 210, it is required that the inclination amplitude gradually decreases from the tail to the body 120. In this embodiment, only one inclined screen plate 210 is used as an example for description.

[0034] In addition, the lower mesh plate includes a first mesh plate 221 and a second mesh plate 222, and the angle α between the first mesh plate 221 and the second mesh plate 222 is less than 180 degrees and greater than 175 degrees. The connecting end of the first mesh plate 221 and the second mesh plate 222 is the lower end. This setting forms a transition by connecting the second mesh plate 222 with the inclined mesh plate 210, and forms a transition with the mesh plate on the head 110 through the first mesh plate 221, which slightly changes the concentrated area of ​​​​the water flow and the cloth to avoid the cloth being too concentrated on the head 110.

[0035] The front water collecting tank 130 and the rear water collecting tank 140 are both installed on the cylinder body 120, and the front water collecting tank 130 and the rear water collecting tank 140 are both located below the mesh plate, wherein the front water collecting tank 130 is located below the first mesh plate 221, and the rear water collecting tank 140 is located at one end of the inclined mesh plate 210 close to the second mesh plate 222.

[0036] In addition, the opening of the front water collection tank 130 is larger than the opening of the rear water collection tank 140, ensuring that the front water collection tank 130 is used as the main water collection port. The front water collection tank 130 and the rear water collection tank 140 are both connected to the pump 300 through pipes, and the dye solution is sent to the tail of the machine for reflux through the pump 300. The pipes connecting the front water collection tank 130 and the rear water collection tank 140 with the pump 300 are both provided with a flow regulating valve 400, and the water outlet ratio of the front water collection tank 130 and the rear water collection tank 140 is further adjusted through the flow regulating valve 400.

[0037] A water flow regulating valve 500 for controlling the water flow size below the screen is also provided on the body 120 of the dyeing drum 100. The water flow regulating valve 500 is arranged between the front water collecting tank 130 and the rear water collecting tank 140, and the water flow regulating valve 500 is also arranged below the inclined screen 210, so that the distance between the water flow regulating valve 500 and the front water collecting tank 130 is 5-10 times the distance between the water flow regulating valve 500 and the rear water collecting tank 140, and 7 times or 8 times is usually selected. If the distance is too small, it is easy to cause the distance between the front water collecting tank 130 and the machine head 110 to be too large, which easily causes the cloth to accumulate on the machine head 110 and increase its weight.

[0038] The water flow regulating valve 500 is close to the rear water collecting tank 140, so that the diverted water flow can be directly sent out from the rear water collecting tank 140. On the one hand, it can improve the diversion effect, and on the other hand, it can reduce or even avoid the impact of the water flow and the fabric on the mesh plate when the water flow is blocked by the water flow regulating valve 500.

[0039] like Figure 2 and Figure 3 As shown, the water flow regulating valve 500 includes a fixed sealing plate 510 fixedly installed in the cylinder body 120, a rotating shaft 520 rotatably installed on the fixed sealing plate 510, a valve plate 530 fixedly installed on the rotating shaft 520, a graduated toothed disk 540 fixedly installed on the cylinder body 120 or the fixed sealing plate 510, and a handle 550 installed on the rotating shaft 520 and capable of cooperating with the graduated toothed disk 540, wherein the principle of the regulation is to drive the rotating shaft 520 to rotate by the handle 550, and then control the rotation of the valve plate 530, and the rotation of the valve plate 530 can realize the control of the size of the water flow below the mesh plate.

[0040] In addition, a brake handle 560 is provided on the handle 550, and locking and unlocking are achieved by the cooperation between the brake handle 560 and the scale toothed disk 540. When in use again, the brake handle 560 is held firmly to rotate it to release the cooperation with the scale toothed disk 540. When the brake handle 560 is released and the brake handle 560 is aligned with the scale toothed disk 540, the brake handle 560 will automatically reset and re-coordinate with the scale toothed disk 540 to lock the handle 550. In this way, the water flow regulating valve 500 can have multiple opening and closing sizes, thereby controlling the water flow, and precise control can be achieved through the scale on the scale toothed disk 540.

[0041] Reference Figure 2 When the water flow regulating valve 500 is in a closed state, a buffer gap is provided between the valve plate 530 and the inclined mesh plate 210, and the height of the buffer gap is h as shown in the figure, and the height h is not greater than one third of the maximum height H of the valve plate 530. Through the design of the buffer gap, the water flow below the inclined mesh plate 210 will not be completely blocked by the valve plate 530, so that the impact of the water flow on the inclined mesh plate 210 after the water flow is blocked by the valve plate 530 can be reduced.

[0042] Example 2: Figure 4 As shown, the difference from Example 1 is that the inclined mesh plate 210 located above the water flow regulating valve 500 is formed with a blocking area 211, and the projection of the blocking area 211 in the direction perpendicular to the inclined mesh plate 210 is required to completely cover the area of ​​the water flow regulating valve 500, wherein the projection of the blocking area 211 is the area between the two dotted lines in the figure. The area of ​​the water flow regulating valve 500 is completely covered in order to reduce or even eliminate the impact of the water flow on the upper part of the mesh plate after the water flow is blocked by the water flow regulating valve 500.

[0043] The mesh holes on the blocking area 211 are arranged vertically or tilted from top to bottom toward the machine head 110. In this embodiment, the mesh holes are tilted from top to bottom toward the machine head 110 as an example, that is, an acute angle β is formed as shown in the figure. The tilted mesh holes make the water flow toward the mesh plate and the water flow on the mesh plate form reverse convection, thereby slowing down the running speed of the cloth here.

[0044] Example 3: Figure 5 As shown, the difference from Example 2 is that a flow baffle 212 is provided between the water flow regulating valve 500 and the inclined mesh plate 210, and the projection of the flow baffle 212 in the direction perpendicular to the inclined mesh plate 210 covers the water flow regulating valve 500 and does not cover the rear water collecting tank 140, and the flow baffle 212 is arranged to be tilted downward from the tail to the nose 110, and the tilting amplitude is greater than the inclined mesh plate 210. The inclined flow baffle 212 can guide the water flow under the inclined mesh plate 210, reduce the water flow flowing upward from the inclined mesh plate 210, and avoid interference with the rear water collecting tank 140, resulting in its water output being affected.

[0045] Example 4: Figure 6 As shown, the difference from Example 3 is that the baffle plate 212 is provided with perforations, the baffle plate 212 is arranged parallel to the inclined mesh plate 210, the perforations are arranged vertically or inclined from top to bottom toward the direction of the machine head 110. In this embodiment, the function of the baffle plate 212 is similar to the baffle area 211 in Example 2.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
