Description

Technical Field

[0001] The invention relates to the technical field of fabric dyeing, in particular to an automatic dyeing device for polyester fabric. Background Art

Its main function is to dye textile fiber products such as cotton, linen, silk, wool and various synthetic fibers in a specific chemical dye solution to give textiles rich and colorful colors. Polyester, scientifically known as polyester fiber, is a synthetic fiber made of polyethylene terephthalate PET through spinning and post-processing. It is one of the world's largest and most widely used synthetic fiber varieties, and is widely used in the textile industry for its excellent properties.

[0003] The Chinese invention patent with announcement number CN118223206B discloses a polyester fabric dyeing device, including a shell, a plurality of electric heating tubes are installed in the bottom wall of the shell, a shell cover is installed on one side of the shell, the shell cover is hinged to the shell, a transmission mechanism is installed at one end of the shell, and a rotating mechanism is installed in the inner cavity of the shell. The polyester fabric dyeing device of the invention is compact in design. Compared with traditional large-scale dyeing machines, the volume of the equipment is significantly reduced, and it is more suitable for arrangement and convenient movement in limited space, meeting the space requirements of small-scale production sites such as small enterprises, scientific research institutions and family workshops. In the present invention, the volume of the inner cavity can be adjusted by a baffle mechanism to adapt to fabrics of different widths, reduce dye waste, reduce investment and operating costs, and is suitable for small batch dyeing tasks.

[0025] When in use, the shell 1 is used to hold the dye, and the two ends of the polyester fabric are first clamped and fixed by the clamping components 43 of the main disk 41 and the clamping components 43 of the movable disk 42 respectively, and then the device is powered on, and the electric heating tube starts to heat, providing the required high temperature environment for the dye.

[0026] The clamping assembly 43 adopts two embodiments.

[0027] The first embodiment of the clamping assembly 43, the clamping assembly 43 includes a plurality of abutment columns 431 and a first fixed block 432 in the shape of an "I", two first pull rods 4321 are slidably provided on the first fixed block 432, a first pull handle 4322 is provided on the back of the first pull rod 4321, a first spring 4323 is provided between the first pull handle 4322 and the first fixed block 432, a first clamping block 4324 is provided on the front of the first pull rod 4321, all the abutment columns 431 are evenly distributed on the main disk 41 or the movable disk 42 around the axis of the rotating shaft 3, and the first fixed block 432 is located between two adjacent abutment columns 431.

[0028] The edge of the polyester fabric is wrapped around all the abutment columns 431, and then the two first pull handles 4322 are pulled up respectively, the first pull handle 4322 drives the first pull rod 4321 to move outward, and the first pull rod 4321 drives the first clamping block 4324 to move outward synchronously, and a gap is generated between the bottom of the first clamping block 4324 and the inner bottom wall of the first fixed block 432, and the first spring 4323 is compressed. Then the two ends of the polyester fabric are respectively placed in the two gaps, and the external force is removed. The elastic force of the first spring 4323 can reset the first pull handle 4322, the first pull rod 4321 and the first clamping block 4324, and the first clamping block 4324 clamps the polyester fabric. In order to prevent the clamped polyester fabric from slipping, anti-slip grooves are provided at the bottom of the first clamping block 4324.

[0029] The second embodiment of the clamping assembly 43, the clamping assembly 43 includes a spiral abutment plate 433 and a plurality of second fixed blocks 434, a second pull rod 4341 is slidably provided on the second fixed block 434, a second pull handle 4342 is provided on the back of the second pull rod 4341, a second spring 4343 is provided between the second pull handle 4342 and the second fixed block 434, a second clamping block 4344 is provided on the front of the second pull rod 4341, the abutment plate 433 is arranged on the main disk 41 or the movable disk 42, and all the second fixed blocks 434 are arranged in sequence along the spiral path of the abutment plate 433.

[0030] The edge of the polyester fabric is wound around the abutment plate 433. At the same time, the second pull handle 4342 is pulled up in sequence. The second pull handle 4342 drives the second pull rod 4341 to move outward. The second pull rod 4341 drives the second clamping block 4344 to move outward synchronously. A gap is generated between the bottom of the second clamping block 4344 and the outer wall of the second fixed block 434. The second spring 4343 is compressed. Then, the portion of the polyester fabric edge that passes through the second fixed block 434 is inserted between the second clamping block 4344 and the outer wall of the abutment plate 433. The external force is removed, and the elastic force of the second spring 4343 is The second pull handle 4342, the second pull rod 4341 and the second clamping block 4344 can be reset, and the second clamping block 4344 clamps part of the edge of the polyester fabric. Therefore, the second clamping block 4344 can stably fix the entire edge of one side of the polyester fabric. In order to prevent the edge of the clamped polyester fabric from slipping, anti-slip grooves are provided at the bottom of the second clamping block 4344. Compared with the first embodiment of the clamping assembly 43, this embodiment can be applicable to polyester fabrics with a longer width, and the first embodiment is applicable to polyester fabrics with a shorter width.

[0031] The present invention can also clamp polyester fabrics of different lengths, and only requires adjusting the position of the movable disc 42 .

[0032] Four guide grooves 34 are arranged on the outer wall of the other end of the rotating shaft 3 and are distributed at equal angles around the circumference thereof. The positioning assembly 44 includes a guide slip ring 441. The bottom end of the inner wall of the guide slip ring 441 is provided with two slide bars 442 that slidably cooperate with the guide grooves 34. The upper part of the guide slip ring 441 is provided with two symmetrically arranged locking components 443 for locking the guide slip ring 441 on the rotating shaft 3. The guide slip ring 441 is slidably arranged on the rotating shaft 3.

[0033] The locking component 443 includes a force-bearing plate 4431 and an extrusion plate 4432. The bottom of the force-bearing plate 4431 is provided with a plug-in block 4433 that is plugged into the guide slide groove 34. The bottom of the extrusion plate 4432 is provided with an extrusion block 4434. Both ends of the extrusion plate 4432 are screwed with hexagon socket bolts 4435. The outer wall of the guide slip ring 441 is provided with a first telescopic groove 4411 that is slidably matched with the plug-in block 4433. The top of the first telescopic groove 4411 is provided with a second telescopic groove 4412 that is slidably matched with the force-bearing plate 4431.

The bottom of the third telescopic groove 4413 is provided with two first screw holes that are matched with the hexagon socket bolts 4435.

[0034] The guide slip ring 441 is used to push the moving disc 42 on the rotating shaft 3, thereby changing the distance between the moving disc 42 and the main disc 41, and then all the hexagon socket bolts 4435 are tightened. When tightening, the extrusion plate 4432 is retracted inwardly into the first telescopic groove 4411, and the extrusion plate 4432 drives the extrusion block 4434 to squeeze the force plate 4431, and the force plate 4431 is retracted inwardly in the second telescopic groove 4412, and the force plate 4431 drives the plug-in block 4433 to extend outward from the first telescopic groove 4411, and the plug-in Block 4433 can be inserted into the corresponding guide groove 34, and then the plug-in block 4433 is fixed in the guide groove 34. In order to prevent the plug-in block 4433 from slipping, anti-slip grooves are set at the bottom of the plug-in block 4433, and then the locking of the guide slip ring 441 is completed. After the rotating shaft 3 rotates, the movable disc 42 can also rotate synchronously with the rotating shaft 3. The movable disc 42 can be limited by the cooperation of the slide bar 442 and the guide groove 34 to prevent the movable disc 42 from deflecting when the horizontal adjustment on the rotating shaft 3 occurs.

[0035] The steam ejected from the jet holes 32 behind the back of the movable disc 42 cannot directly act on the polyester fabric, which wastes resources. Therefore, a closing mechanism 5 is set to close part of the jet holes 32. The closing mechanism 5 includes two semicircular sealing plates 51. Two symmetrically arranged connecting ears 52 are provided on both sides of the semicircular sealing plates 51. The connecting ears 52 are provided with second screw holes 521. A hand-tightened screw 522 is screwed into the four second screw holes 521 of one of the semicircular sealing plates 51.

[0037] When the temperature of the dye rises to a certain level, steam begins to be generated, and then the motor 11 drives the driving sprocket 12 to rotate, and the driving sprocket 12 drives the driven sprocket 33 to rotate through the chain, and the driven sprocket 33 drives the rotating shaft 3 to rotate synchronously, and the clamped polyester fabric can rotate synchronously with the rotating shaft 3, and then the conveying mechanism 6 can extract the steam and convey it to the air cavity 31. The conveying mechanism 6 includes a conveying tank 61, an absorption cover 62, a sealing swivel sleeve 63 and a transmission connecting sleeve 64, a piston 611 is slidably provided in the delivery tank 61, a pumping rod 612 is provided at the tail end of the piston 611, the tail end of the pumping rod 612 passes through the delivery tank 61, a limit plate 613 is provided at the tail end of the pumping rod 612, a third spring 614 is provided between the limit plate 613 and the delivery tank 61, an L-shaped transmission rod 615 is provided on the outer wall of the limit plate 613, an air intake pipe 616 is provided on the side wall of the delivery tank 61, an air intake check valve is provided in the air intake pipe 616, and the head end of the delivery tank 61 is provided with a stop plate 613. An outlet pipe 617 is provided, and an outlet check valve is provided in the outlet pipe 617. A connector 631 is provided on the sealing swivel sleeve 63. A linkage rod 641 is provided on the outer wall of the transmission connecting sleeve 64 to abut against the L-shaped transmission rod 615. The rotating shaft 3 includes a main shaft 35 and an auxiliary shaft 36. The main shaft 35 and the auxiliary shaft 36 are both provided with a connecting flange 37. The air cavity 31 is located on the main shaft 35. The driving sprocket 12 is installed on the auxiliary shaft 36. The outer wall of the main shaft 35 close to the connecting flange 37 is provided with a connecting flange 37. The transmission connecting sleeve 64 seals the rotating groove of the rotating match, and a plurality of ventilation grooves 38 evenly distributed around the axis of the main shaft 35 are opened between the rotating groove and the air cavity 31. The conveying tank 61 is fixedly connected to the top of the shell cover 2, and the absorption cover 62 is fixedly connected to the top of the shell cover 2. The air inlet pipe 616 is connected to the absorption cover 62, and one end of the air outlet pipe 617 passes through the shell cover 2. One end of the air outlet pipe 617 is connected to the connector 631 through a pipeline, and the transmission connecting sleeve 64 is fixedly connected to the auxiliary shaft 36.

[0038] The auxiliary shaft 36 rotates synchronously with the driven sprocket 33. The auxiliary shaft 36 not only drives the main shaft 35 to rotate synchronously, but also drives the transmission connection sleeve 64 to rotate synchronously. The linkage rod 641 also rotates synchronously with the transmission connection sleeve 64. The linkage rod 641 can gradually contact the L-shaped transmission rod 615, and the L-shaped transmission rod 615 can move horizontally backward. The L-shaped transmission rod 615 drives the limit plate 613 and the pumping rod 612 to move backward synchronously. The pumping rod 612 drives the piston 611 to move backward synchronously in the conveying tank 61. The third spring 614 is also stretched, and the piston 611 generates a pulling force. Due to the restrictions of the air inlet check valve and the air outlet check valve, the pulling force can only allow steam to enter from the absorption cover 62, and then enter the conveying tank 61 through the air inlet pipe 616. The linkage rod 641 gradually contacts the L-shaped transmission rod 615 as it rotates. The transmission rod 615 disengages, and then the elastic force of the third spring 614 uses its own elastic force to pull the limit plate 613 and the pumping rod 612 forward synchronously, and the pumping rod 612 drives the piston 611 to move forward synchronously in the conveying tank 61, and the piston 611 generates an extrusion force. Due to the restrictions of the air inlet check valve and the air outlet check valve, the extrusion force can only squeeze the steam from the conveying tank 61 into the air outlet pipe 617, and then introduce it into the connector 631 through the pipeline, and then enter the sealing swivel sleeve 63. The steam then enters the air cavity 31 through the ventilation groove 38, and the steam is finally ejected from the jet hole 32. While moving forward, the limit plate 613 also drives the L-shaped transmission rod 615 to reset, and the linkage rod 641 continuously contacts the L-shaped transmission rod 615, thereby realizing continuous extraction of steam for transportation.
