Description

Technical Field

[0001] This utility model relates to the field of fabric pressing in fabric dyeing machines, specifically a fabric pressing mechanism for an airflow dyeing machine. Background Technology

[0002] Airflow dyeing machine uses high-speed airflow to drive dye liquor to dye fabric. After dyeing, the fabric is pulled out from the outlet of the airflow dyeing machine and passes through the fabric pressing mechanism. Two pressure rollers apply a certain pressure to the fabric under the elastic force of springs, squeezing out the waste dye liquor from the fabric. The waste dye liquor flows vertically downward along the length of the pressure rollers and falls into the collection hopper, and then is discharged to a designated location such as a drainage ditch through a drain pipe.

[0003] The existing fabric pressing mechanism requires two workers to adjust the positions of both ends of the upper pressure roller simultaneously, and the positions of both ends of the upper pressure roller need to be calibrated after adjustment to ensure that both ends of the upper pressure roller are at the same height, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a fabric pressing mechanism for an airflow dyeing machine in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric pressing mechanism for an airflow dyeing machine, comprising a lower mounting frame and an upper mounting frame installed at the output port of the airflow dyeing machine. The upper mounting frame is located directly above the lower mounting frame. A lower pressure roller is rotatably mounted on the inner side of the lower mounting frame. A funnel is mounted on the inner side of the lower mounting frame below the lower pressure roller. The output end of the funnel is connected to a waste liquid collection tank via a pipe. A connecting frame is fixedly mounted at the bottom of the upper mounting frame. The connecting frame is connected to a movable frame via an adjustment mechanism. An upper pressure roller is rotatably mounted on the inner side of the movable frame. The adjustment mechanism includes a rotating component and a lifting component.

[0006] As a further embodiment of this utility model: the rotating assembly includes a bracket fixedly installed on the outer side of the longitudinal plate of the upper mounting frame, a worm gear rotatably installed between the two transverse plates of the bracket, the top shaft of the worm gear extending through to the top of the bracket, and a handle fixedly installed at the top of the top shaft of the worm gear, and a worm wheel meshing with the outer periphery of the worm gear.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4In this embodiment of the present invention, a fabric pressing mechanism for an airflow dyeing machine includes a lower mounting frame 1 and an upper mounting frame 2 installed at the output port of the airflow dyeing machine. The upper mounting frame 2 is located directly above the lower mounting frame 1. A lower pressure roller 5 is rotatably mounted on the inner side of the lower mounting frame 1. A funnel 10 is installed on the inner side of the lower mounting frame 1 below the lower pressure roller 5. The output end of the funnel 10 is connected to a waste liquid collection tank through a pipe. A connecting frame 3 is fixedly mounted on the bottom end of the upper mounting frame 2. The connecting frame 3 is connected to a movable frame 4 through an adjustment mechanism. An upper pressure roller 9 is rotatably mounted on the inner side of the movable frame 4. The adjustment mechanism includes a rotating component and a lifting component.

[0019] In this embodiment: First, one end of the fabric dyed by the airflow dyeing machine is passed through the space between the upper pressure roller 9 and the lower pressure roller 5. Then, the rotating assembly is rotated according to the thickness of the fabric. When the rotating mechanism rotates, it squeezes or releases the pressure on the bottom end of the movable frame 4. At this time, the movable frame 4 can move upward under the pressure through the lifting mechanism, or move downward under the pressure release through the lifting mechanism. The movable frame 4 moving upward or downward can drive the upper pressure roller 9 connected to it to move synchronously. During the movement of the fabric, the upper pressure roller 9 and the lower pressure roller 5 cooperate to squeeze the upper and lower surfaces of the fabric. The liquid contained in the fabric is squeezed out under pressure. After the liquid is squeezed out, it drips downward under gravity and enters the funnel 10. Then, it is pumped into the waste liquid collection tank by the waste liquid pump.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The rotating assembly includes a bracket 11 fixedly installed on the outer side of the longitudinal plate of the upper mounting frame 2. A worm gear 12 is rotatably installed between the two transverse plates of the bracket 11. The top shaft of the worm gear 12 extends through to the top of the bracket 11, and a handle 14 is fixedly installed at the top of the top shaft of the worm gear 12. The outer periphery of the worm gear 12 meshes with a worm wheel 13. The rotating assembly also includes rotating ears 6 fixedly installed at both ends of the top of the connecting frame 3. A synchronous shaft 8 coaxially connected to the worm wheel 13 is rotatably installed inside the rotating ears 6. A downwardly extending swing arm 15 is interference-fitted on the outer wall of the synchronous shaft 8. An inwardly protruding pressure rod 16 is rotatably installed on the lower inner side of the swing arm 15. The outer periphery of the pressure rod 16 abuts against the bottom end of the movable frame 4.

[0021] In this embodiment: by rotating the handle 14, the handle 14 drives the worm gear 12 to rotate, the rotating worm gear 12 drives the meshing worm wheel 13 to rotate, the worm wheel 13 drives the synchronous shaft 8 connected to it to rotate, and when the synchronous shaft 8 rotates, it drives the swing arm 15 to rotate around the center of the synchronous shaft 8. At this time, the pressure rod 16 connected to the swing arm 15 rotates in a circle. If the pressure rod 16 rotates downward, it will cancel the squeezing of the bottom end of the movable frame 4. At this time, the lifting assembly will reset, and the upper pressure roller 9 will move downward. If the pressure rod 16 rotates upward, it will apply squeezing force to the bottom end of the movable frame 4. At this time, the lifting assembly will be compressed, and the upper pressure roller 9 will move upward, thereby adjusting the distance between the upper pressure roller 9 and the lower pressure roller 5 to meet the needs of fabrics of different thicknesses.

[0022] The worm gear 12 drives the worm wheel 13 to rotate, which has a good anti-reverse effect and can keep the upper pressure roller 9 in the current position after adjustment.

[0023] Please refer to this carefully. Figure 3 and Figure 4 The lifting assembly includes a sliding shaft 17 that is fixedly connected to the top of the movable frame 4 and extends upward. The sliding shaft 17 is slidably connected to the connecting frame 3. A spring 18 is abutted between the bottom end of the connecting frame 3 and the top end of the movable frame 4. The spring 18 is sleeved with the sliding shaft 17.

[0024] In this embodiment: during the rotation of the pressure rod 16, if the bottom end of the movable frame 4 is squeezed, the movable frame 4 will drive the sliding shaft 17 to slide upward. At this time, the spring 18 will be further compressed. If the bottom limit of the movable frame 4 is canceled, the spring 18 will reset and push the movable frame 4 to move downward. At this time, the sliding shaft 17 will move downward.

[0025] Please refer to this carefully. Figure 1 A support frame 7 is fixedly installed on the top of the connecting frame 3, and the support frame 7 is rotatably connected to the synchronous shaft 8.

[0026] In this embodiment, the design of the support frame 7 can maintain the rotational stability of the synchronous shaft 8.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
