Description

Technical Field

[0001] The present application relates to the field of airflow dyeing machines, and in particular to a discharging device of an airflow dyeing machine. Background Art

[0002] Polyester is a fiber-forming polymer made from purified terephthalic acid (or dimethyl terephthalate) and ethylene glycol through esterification, transesterification, and polycondensation. The fibers, produced through spinning and post-processing, are known for their excellent wrinkle resistance and shape retention. Polyester fabric production typically requires dyeing, typically using an airflow dyeing machine.

[0003] The Chinese patent with the authorization announcement number CN220550347U discloses a cloth discharging device for an airflow dyeing machine, comprising a frame, a squeezing roller assembly rotatably connected to the frame, a guide trough connected to the frame, and a recovery trough. The recovery trough is connected to a first filter plate, a brush member, and a movable assembly. The inner walls of both sides of the recovery trough are provided with strip holes. The movable assembly is used to drive the brush member to slide along the length of the recovery trough and is connected to the top of the first filter plate. The brush member is used to clean the top of the first filter plate. The brush member cleans the fluff on the first filter plate. Some of the fluff is pushed by the brush member and falls out of the recovery trough through the strip holes, thereby reducing the fluff on the first filter plate, minimizing the clogging of the first filter plate by the fluff, and increasing the rate at which the dye passes through the first filter plate, thereby improving the filtration efficiency.

[0004] Regarding the above-mentioned related technologies, there is a large height difference between the squeezing roller group and the first filter plate. When the dye liquid drips from the squeezing roller group to the first filter plate, the dye liquid collides with the first filter plate, causing the dye liquid to splash, thereby causing waste of dye liquid.

[0049] Reference Figure 3 The connection box 300 is connected to a rotating rod 360 at both ends along its length. The length of the rotating rod 360 is consistent with the length of the connection box 300. The end of the rotating rod 360 away from the connection box 300 is connected to a moving block 370. The frame 100 is provided with a moving slot 130. The length of the moving slot 130 is consistent with the vertical direction. There are two moving slots 130, and the two moving slots 130 are respectively located on both sides of the connection box 300 along the length direction.

The length direction of the moving block 370 is consistent with the length direction of the rotating rod 360. The moving block 370 is threadedly sleeved on the screw rod 610 along its length direction and away from one end of the rotating rod 360.

[0051] Reference Figure 3 A clearance hole 140 is defined within the inner wall of the movable slot 130, located near the connection port 330. This clearance hole 140 is located along the longitudinal direction of the connection box 300, with the longitudinal direction of the clearance hole 140 aligned with the vertical direction. The drain pipe 310 is a flexible hose, and the end of the drain pipe 310, located away from the connection box 300, is connected to the inner wall of the recovery box 110, near the clearance hole 140. When the connection box 300 moves vertically, the drain pipe 310 folds and passes through the clearance hole 140.

[0052] The second motor 620 drives the screw rod 610 to rotate, so that the moving block 370 slides vertically and is connected to the moving groove 130, driving the connection box 300 to move vertically, thereby facilitating the operator to clean the connection box 300.

[0053] Reference Figure 3 and Figure 7The movable block 370 has a rotation slot 371 formed along its length and on the side proximal to the connection box 300. The end of the rotation rod 360, which is away from the connection box 300, is embedded in the rotation slot 371. The rotation rod 360 is rotatably connected to the rotation slot 371. The rotation rod 360 is connected to a locking assembly 700, which is used to lock the rotation rod 360 in the rotation slot 371. When the locking assembly 700 locks the rotation rod 360 in the rotation slot 371, the connection box 300 is positioned horizontally.

[0054] Reference Figure 3 and Figure 7 The rotating rod 360 has a mounting groove 361 defined around its periphery. The length of the mounting groove 361 is aligned with the radial direction of the rotating rod 360. The locking assembly 700 includes a locking block 710 and a spring 720. The length of the spring 720 is aligned with the length of the mounting groove 361.

The length of the locking groove 372 is aligned with the vertical direction. When the locking block 710 is inserted into the locking groove 372, the connection box 300 is positioned horizontally.

[0055] Reference Figure 3 and Figure 7 The frame 100 is connected to a push rod 150, which is located directly below the locking groove 372. The length of the push rod 150 is consistent with the vertical direction. A connecting channel 373 is provided at the bottom of the locking groove 372. The length of the connecting channel 373 is consistent with the vertical direction, and the bottom of the connecting channel 373 is open.

[0056] Reference Figure 1 and Figure 7 The rotating rod 360 is connected to a reset member, which is a torsion spring 362. One end of the torsion spring 362 is connected to the moving block 370, and the other end of the torsion spring 362 is connected to the rotating rod 360. When the connection box 300 is set horizontally, the torsion spring 362 is deformed. When the locking block 710 is away from the locking groove 372, the torsion spring 362 drives the connection box 300 to rotate and makes the opening of the connection box 300 tilted toward the side away from the guide plate 120. When the torsion spring 362 is relaxed, the connection box 300 is tilted.

[0057] When in use, the connection box 300 is set horizontally, the locking block 710 is embedded in the locking groove 372, and the torsion spring 362 is deformed. When cleaning the connection box 300, the connection box 300 moves downward in the vertical direction, and the push rod 150 is embedded in the connection channel 373. The push rod 150 approaches the locking block 710 and pushes the locking block 710 to be embedded in the locking groove 372. The torsion spring 362 restores its shape and drives the locking block 710 away from the locking groove 372, so that the top opening of the connection box 300 is tilted toward the side away from the guide plate 120, so as to facilitate the operator to clean the connection box 300.

[0058] The implementation principle of the discharge device of an air flow dyeing machine in the embodiment of the present application is as follows: after the fabric is dyed, it is taken out from the dyeing machine body and passes through two squeezing rollers 210. During the process of transporting the fabric to the squeezing rollers 210, some excess dye drops onto the guide plate 120 and flows along the guide plate 120 to the recovery box 110. The dye passes through the second filter plate 112 and is collected in the recovery box 110. When the squeezing rollers 210 squeeze the fabric, the dye squeezed out of the fabric drops into the connecting box 300. The dye passes through the first filter plate 340, which filters the dye to reduce impurities in the dye. The dye moves along the drain pipe 310 to the recovery box 110 and is collected in the recovery box 110. The height difference between the connecting box 300 and the squeezing rollers 210 is small, which can minimize the splashing of dye and reduce the waste of dye.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
