Description

Technical Field

[0001] The utility model relates to the field of dyeing machines, in particular to a cloth pressing device of a dyeing machine. Background Art

[0002] At present, the fabrics in the storage tank of all intermittent (jet, gas-liquid or airflow) dyeing machines mainly rely on their own weight to slide down and push the fabrics forward. Due to the limitation of the main cylinder structure of the dyeing machine, the fabrics must be piled up to a certain height (a certain height difference is formed between the front and rear piles) to generate downward pressure to push the front part of the fabric to run. To a large extent, the gravity of the absorbed water contained in the fabric is required to push it, and it only acts downward. It is difficult for the front half of the fabric to move upward. However, under the condition of small bath ratio, it is difficult to push the fabric forward due to the low water content. In addition, for hydrophobic fibers or fabric fibers that are not soaked by water at the beginning, the fabric capacity is often reduced due to fluffiness. Summary of the invention

[0020] See also Figures 1 to 3 A cloth pressing device of a dyeing machine includes a cloth storage tank 2 arranged in a main cylinder 1. A cloth guide pipe 3 is also arranged at the upper end of the main cylinder 1, a cloth lifting roller 4 is arranged above the cloth guide pipe 3, and a nozzle 5 is arranged at the lower left side of the cloth lifting roller 4. The cloth lifting roller 4 and the nozzle 5 pull the fabric 8 to circulate in the dyeing machine. The above structure is a conventional structure of the dyeing machine and will not be described in detail here.

[0021] The cloth storage tank 2 is provided with a cloth pressing unit 6. The cloth pressing unit 6 includes a cloth pressing plate 62 connected to a rotating shaft 61, the rotating shaft 61 is parallel to the center line of the main cylinder 1, and the rotating shaft 61 is driven to rotate by a transmission component 7. The rotating shaft 61 passes through a flange seat 67 on the main cylinder 1 and is connected to a coupling 73, and a sealing ring 65 and a bushing 66 are provided between the rotating shaft 61 and the flange seat 67. The transmission component 7 is connected to the rear side of the main cylinder 1 through a support. The transmission component 7 includes a motor 71 and a reducer 72, and the motor 71 drives the rotating shaft 61 to rotate through the reducer 72 and the coupling 73. The rotating shaft 61 is driven to rotate by the transmission component 7, so that the rotation drives the cloth pressing unit 6 to reciprocate, and the rotation angle of the rotating shaft 61 is limited to within 100°. The transmission component 7 can also adopt conventional power components such as cylinders, as long as the reciprocating rotation of the rotating shaft 61 can be achieved, and is not limited to the conventional driving mode of the motor 71 and the reducer 72.

[0022] The front end of the cloth pressing plate 62 is connected to an arc plate 63, and the cloth pressing plate 62 is located on the inner side of the fabric 8 in the cloth storage tank 2. The arc plate 63 is also connected to a side connecting plate 64, and the arc plate 63, the cloth pressing plate 62 and the side connecting plate 64 form a fan-shaped column structure. The side connecting plate 64 and the cloth pressing plate 62 are fixedly connected to the rotating shaft 61 through a connecting flange or a sleeve. The cloth pressing unit 6 is composed of the arc plate 63, the cloth pressing plate 62 and the side connecting plate 64. When the rotating shaft 61 rotates counterclockwise, the cloth pressing plate 62 rotates to contact the fabric 8 and push the fabric 8 to move. When the rotating shaft 61 rotates clockwise, the cloth pressing plate 62 reverses to make the arc plate 63 slide over the fabric 8 and then reset. The rotation angle of the cloth pressing plate 62 is the same as the rotation angle of the rotating shaft 61, both of which are less than 100°. Figure 1 The bottom surface of the cloth pressing plate 62 partially or entirely contacts the fabric 8, thereby applying a thrust to the fabric, so that the fabric 8 can move rapidly counterclockwise in the fabric storage tank 2. Figure 2 When the cloth pressing plate 62 rotates clockwise, the arc plate 63 contacts the inner side of the fabric 8. At this time, the cloth pressing plate 62 does not contact the fabric 8, ensuring that the cloth pressing plate 62 can be smoothly reset to avoid affecting the normal counterclockwise movement of the fabric 8 when the cloth pressing plate 62 rotates clockwise. The cloth pressing unit 6 reciprocates and the fabric 8 in the cloth storage tank 2 is pressed and fed forward in an orderly manner according to the set program.

[0023] The cloth storage tank 2 is divided into 2, 3 or more independent cloth storage chambers along the axial direction of the main cylinder 1, and each cloth storage chamber is provided with a cloth pressing device.

[0024] Different from the prior art, the cloth pressing device of the dyeing machine of the utility model can push the fabrics in the storage tank to slide, reduce the mutual squeezing force between the fabrics, and increase the effective cloth storage space of the fabric storage tank.

[0025] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
