Description

Technical Field

[0001] The invention relates to the technical field of dyeing, in particular to a cloth discharging device of an overflow dyeing machine. Background Art

[0002] Overflow dyeing is a loose intermittent dyeing process that places the fabric under the liquid surface. The overflow dyeing machine is a dyeing vat about ten meters long with a rotating wheel inside to drive the fabric to rotate. At the bottom of the dyeing machine is a thick and long dyeing vat where the dye liquid is. The dyeing process of the fabric mainly depends on the dyeing in the lower dyeing vat. By controlling the running speed of the fabric, the soaking time of the fabric in the dyeing vat is controlled, and the dyeing effect is also controlled.

[0003] In the existing overflow dyeing machine, when discharging materials, the fabric is directly pulled out of the dye vat under the drive of the fabric discharging motor. When the pulled fabric falls into the storage box, the fabric falling point is fixed, which causes the fabric to pile up quickly and exceed the height of the storage box, while other parts of the storage box are still empty. At this time, the staff is required to manually move the fabric to the empty area of ​​the storage box, or move the storage box so that the empty area of ​​the storage box is located below the fabric falling point. Since the fabric absorbs a large amount of dye, the actions of moving the fabric and moving the storage box are extremely laborious, and the work intensity of the staff is high. Based on this, a fabric discharging device for an overflow dyeing machine is provided. Summary of the invention

The eccentric boss 305 is fixed at the eccentric position of the side of the passive gear 212. The two ends of the transmission arm 306 are rotatably connected to the eccentric boss 305 and the swing arm 304 respectively. When the passive gear 212 rotates, the eccentric boss 305 and the swing arm 304 are used to realize the reciprocating rotation of the rotating shaft 301; The falling fabric passes through the rectangular material shifting frame 303, and the reciprocating swing of the rectangular material shifting frame 303 is used to shift the fabric back and forth; An extension arm is formed at the front end of the fixed plate 203, and a convex guide roller 213 is fixed to one side of the extension arm. The convex guide roller 213 and the cloth outlet roller 208 are distributed on the same side and below the front end of the cloth outlet roller 208; The top level of the rectangular material-selecting frame 303 is lower than the level of the convex guide roller 213 .

[0018] In this embodiment: when the cloth discharging device is used, it is placed at the front end of the overflow dyeing machine, and its guide ring 103 is close to the overflow dyeing machine and the center of the guide ring 103 coincides with the center line of the overflow dyeing machine (it should be noted that the guide ring 103 is located at the center of the concave top frame 102); When performing the cloth discharging operation, the operating steps are as follows: First, manually pass the end of the fabric to be discharged through the guide ring 103, the upper surface of the cloth discharge roller 208, the upper surface of the convex guide roller 213, and the rectangular material feeding frame 303 in sequence, and finally fall into the storage box placed in the middle of the four pillars 101; Afterwards, the cloth discharging motor 206 is started, and the cloth discharging motor 206 drives the cloth discharging roller 208 and the driving gear 209 to rotate through the T-type double-axis steering box 207 (it should be noted that the T-type double-axis steering box 207 is a T-series spiral bevel gear steering box, which is a commonly used transmission device in the machinery industry, and its internal structure is not elaborated in detail here). When the cloth discharging roller 208 rotates, the friction force with the fabric forms a pulling force on the fabric, so that the fabric is moved out of the overflow dyeing machine, and slides down along the inclined distribution track of the convex guide roller 213 and the rectangular material diverting frame 303 into the storage box; At the same time, the driving gear 209 drives the gear roller 210 to rotate, the gear roller 210 drives the transmission gear 211 to rotate, the transmission gear 211 drives the passive gear 212 to rotate, and the passive gear 212 drives the reciprocating screw rod 202 to rotate, so that the fixed plate 203, the sliding sleeve 204, the reciprocating seat 205, the cloth discharging motor 206, the T-shaped double-axis steering box 207, the cloth discharging roller 208, the driving gear 209, and the convex guide roller 213 can be reciprocated horizontally as a whole. In this process, the sliding sleeve 204 slides along the outer wall of the guide rod 201 to achieve limited movement and unidirectional movement, and the driving gear 209 keeps a meshing transmission state with the gear roller 210 during the movement. Through the reciprocating movement of the cloth discharging roller 208 and the convex guide roller 213, the landing point of the fabric falling into the storage box can be changed left and right; (It should be noted that the large diameter parts on the sides of the cloth outlet roller 208 and the convex guide roller 213 can limit the fabric during the left and right movement to prevent the fabric from being separated from the cloth outlet roller 208 and the convex guide roller 213); In addition, when the passive gear 212 rotates, it drives the eccentric boss 305 to rotate in a circle, and through the transmission of the transmission arm 306 and the swing arm 304, the rotating shaft 301 rotates back and forth, and then the arc arm 302 and the rectangular material selection frame 303 swing back and forth. In this way, the fabric passing through the rectangular material selection frame 303 is driven to swing back and forth, and the fabric will fall into the storage box in an "S" shape. With the change of the left and right position of the fabric, the fabric can be evenly spread throughout the entire storage box. Compared with the traditional manual operation of shifting the fabric or adjusting the position of the storage box, the participation of the staff is reduced, and the work intensity of the staff is further reduced.

[0019] Please refer to Figures 1 to 4 The length of the spiral groove on the outer wall of the reciprocating screw 202 is smaller than the length of the gear roller 210 .

[0020] In this embodiment: through this structure, the moving stroke of the driving gear 209 can be made smaller than the length of the gear roller 210, avoiding contact and collision between the driving gear 209 and the concave top frame 102, thereby ensuring stable operation of the equipment.

[0021] Please refer to Figures 1 to 4The transmission gear 211, the driven gear 212, the swing arm 304, the eccentric boss 305, and the transmission arm 306 are symmetrically arranged in two groups with the center line of the concave top frame 102 as the center.

[0022] In this embodiment, the arrangement of this structure can balance the forces on both sides of the gear roller 210, the reciprocating screw rod 202, and the rotating shaft 301, making the overall operation of the equipment more stable and smooth.

[0023] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
