Technical Field

[0001] The utility model relates to the field of dyeing and finishing devices, and more specifically, to a dyeing and finishing device for polyester-cotton knitted fabrics. Background Art

[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method, which is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. The existing knitted fabric dyeing and finishing equipment usually puts the fabric into a dye device filled with dyeing solution for soaking to color the fabric, and then uses a conveyor roller to convey the fabric out. The fabric will absorb a part of the solution after being dyed and conveyed out. However, for the dyed fabric, due to excessive dye contamination, it is easy to cause the dye to drip everywhere. Usually, the fabric is squeezed to squeeze out the dye absorbed in the fabric, but squeezing the fabric alone cannot effectively squeeze out the dye in the fabric.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a dyeing and finishing device for polyester-cotton knitted fabrics.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] Example:

[0017] A polyester-cotton knitted fabric dyeing and finishing device, such as Figures 1 to 3As shown in the figure, it includes a feed inlet and a discharge outlet 2 respectively opened on the dyeing tank 1. A guiding frame 3 connected to the discharge outlet 2 is welded on the side wall of the dyeing tank 1. The guiding frame 3 is arranged corresponding to the discharge outlet 2. A pressing roller 4 is rotatably connected to the inner wall of the guiding frame 3. The pressing roller 4 rotates on the inner side wall of the guiding frame 3 through a rotating shaft. The inner bottom surface of the guiding frame 3 is an inclined surface, and the height of the inner bottom surface of the guiding frame 3 gradually increases along the direction away from the dyeing tank 1. The height of the inner bottom surface of the guiding frame 3 close to the dyeing tank 1 is less than the height of the inner bottom surface of the guiding frame 3 away from the dyeing tank 1. The pressing roller 4 is located above the inner bottom surface of the guiding frame 3 and there is a gap between them. A bottom plate 5 is welded on the side wall of the dyeing tank 1 close to the guiding frame 3. A retaining wall 6 is welded on the top surface of the bottom plate 5. The top of the retaining wall 6 is open. A vertically arranged roller 7 is rotatably connected inside the retaining wall 6. A plurality of filter holes are arranged in a circumferential array on the outer peripheral wall of the roller 7. There is a spacing between the roller 7 and the retaining wall 6. The height of the roller 7 is less than or equal to the height of the retaining wall 6. The guiding frame 3 is located above the retaining wall 6. The top surface of the bottom plate 5 is rotatably connected with a mounting plate 8 through a motor. The mounting plate 8 is horizontally arranged. The motor is located at the bottom of the bottom plate 5 and does not contact the ground. An installation groove 9 for the bottom of the roller 7 to be inserted into is opened on the top of the mounting plate 8. A cover plate 10 is threadedly connected to the top of the roller 7. A threaded ring is welded on the bottom surface of the cover plate 10. Internal threads for connecting the threaded ring are arranged on the inner peripheral wall of the roller 7. The retaining wall 6 includes a fixed frame 14 and a rotating plate 15. The fixed frame 14 is welded on the top surface of the bottom plate 5. The cross-section of the fixed frame 14 is in a U-shaped setting. One side of the fixed frame 14 away from the guiding frame 3 is open. The roller 7 is located inside the fixed frame 14. The rotating plate 15 is rotatably connected to the side wall of the fixed frame 14 away from the guiding frame 3 through a torsion spring. An inclined plate 16 is welded on the side wall of the guiding frame 3 away from the dyeing tank 1. The height of the inclined plate 16 gradually decreases along the direction close to the fixed frame 14. The height of one side of the inclined plate 16 close to the guiding frame 3 is greater than the height of one side of the inclined plate 16 away from the guiding frame 3. The inclined plate 16 is located above the fixed frame 14.

[0018] The fabric is transported from the feed inlet into the dyeing tank 1 filled with the dyeing solution for dyeing the fabric. When the fabric is taken out from the discharge outlet 2 after being dyed in the dyeing tank 1, the fabric will adsorb part of the solution from the dyeing tank 1. At this time, the fabric adsorbed with the solution is first transported to the discharge outlet 2 and then to the guiding frame 3, so that the fabric is in contact with the inner bottom surface of the guiding frame 3, and the fabric will pass through the gap between the pressing roller 4 and the inner bottom surface of the guiding frame 3, and the pressing roller 4 will roll and press on the fabric to play an extrusion role. Because the inner bottom surface of the guiding frame 3 is an inclined surface, and the height of the inner bottom surface of the guiding frame 3 gradually increases along the direction away from the dyeing tank 1, part of the solution extruded by the pressing roller 4 can flow obliquely downward along the inclined direction of the inner bottom surface of the guiding frame 3 and back into the dyeing tank 1, which can play a role in initially filtering the solution.

[0019] After that, the cloth after the preliminary solution is filtered is separated from the guide frame 3 and transported downward along the inclined plate 16 to the drum 7. The inclined plate 16 can play a guiding role. At this time, the rotating plate 15 is rotated by the torsion spring until the fixed frame 14 is away from the opening of the guide frame 3 and exposed to the outside. Then, the drum 7 is passed through the fixed frame 14 away from the opening of the guide frame 3, and the bottom of the drum 7 is stuck in the mounting groove 9 on the mounting plate 8. The rotating plate 15 is then turned back to cover the opening of the fixed frame 14 away from the guide frame 3. At this time, the drum 7 is surrounded by the fixed frame 14 and the rotating plate 15 respectively. When the cloth is accommodated in the drum 7, the cover plate 10 is installed so that the threaded ring on the cover plate 10 is connected to the internal thread of the inner circumferential wall of the drum 7. Then, the mounting plate 8 is driven by the motor to The installation disc 8 rotates horizontally, and the installation disc 8 drives the drum 7 and the cloth in the drum 7 to rotate in the same direction respectively when rotating. At this time, the remaining residual solution is thrown out from the multiple filter holes on the drum 7 into the enclosure 6 through the action of centrifugal force, so that the remaining solution is thrown onto the fixed frame 14 and the rotating plate 15 respectively, to prevent the solution from being directly thrown out from the drum 7 to the surrounding area to cause pollution. The cover plate 10 is installed at the top opening of the drum 7 to prevent the cloth from being separated from the drum 7 when the drum 7 rotates, so that the cloth is first squeezed by the pressure roller 4 in the guide frame 3 for preliminary filtration, and then the cloth is placed in the drum 7 and the remaining solution is filtered by rotating the drum 7, thereby shortening the time required for filtering the solution in the cloth and improving the efficiency of the solution being separated from the cloth.

[0020] After the cloth passes through the drum 7 to filter the remaining solution, the rotating plate 15 is first rotated to make the fixed frame 14 away from the opening of the guide frame 3 and exposed to the outside. Then, the drum 7 is disassembled to make its bottom detach from the mounting groove 9 and then taken out from the opening of the fixed frame 14. Finally, the cover plate 10 is removed to make the threaded ring detach from the inner wall of the drum 7, and then the cloth with the filtrate is taken out from the drum 7.

[0021] A plurality of hanging rings 11 are welded to the outer peripheral wall of the drum 7, and a plurality of elastic bands 12 are bonded to the top surface of the mounting disk 8. The number of hanging rings 11 and elastic bands 12 is the same, and one end of the elastic band 12 is bonded with a hook 13 for hooking the hanging ring 11. When the bottom of the drum 7 is stuck in the mounting groove 9 on the mounting disk 8, the elastic band 12 is first stretched to cause it to undergo stretching deformation. In the process of stretching the elastic band 12, the hook 13 is driven to move toward the direction close to the hanging ring 11 until the hook 13 is hooked in the hanging ring 11. After that, when the motor drives the mounting disk 8, the drum 7 and the cloth in the drum 7 to rotate respectively, the hanging ring 11 is hooked by the hook 13, so that the drum 7 can avoid the upper and lower position deviation of the drum 7 in the mounting groove 9 during the horizontal circumferential rotation, thereby improving the stability of the drum 7 during the rotation.

[0022] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
