Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament texturing, and particularly relates to a polyester filament texturing device. Background Technique

[0002] Polyester filament texturing is a process of special treatment for polyester fabrics or polyester filaments, aiming to enhance their elasticity and comfort.

[0003] The technological process of polyester filament texturing mainly includes the following steps: Pretreatment: Wash the polyester filaments and remove impurities to ensure the cleanliness of the raw materials; Stretching and texturing: Stretch the polyester filaments through special texturing equipment to elongate them and enhance their elasticity. In this process, the polyester filaments will be subjected to tensile force and false twist torsion force, resulting in tensile deformation; Fixing and texturing: The stretched polyester filaments need to be heat-set to fix their shape and elasticity, which is usually achieved by methods such as hot air or high-temperature water immersion; Cooling and setting: The polyester filaments after heat-setting are cooled to further fix their shape and elasticity.

[0004] In the production of polyester filament texturing, it is necessary to pretreat the polyester filaments, that is, to remove the impurities in the polyester filaments by washing. After the impurities in the polyester filaments are washed clean, for the subsequent texturing process, it is necessary to dry the polyester filaments. However, in most existing drying processes, the processes of washing and drying the polyester filaments are separated and two devices are required, which increases the production cost to a certain extent.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation mode.

[0027] In specific implementation, the water outlet assembly 4 is in a closed state, and the water added to the cylinder 3 will not flow out. When the two electric telescopic rods 2 are started and their piston rods are extended, the position of the cylinder 3 is driven to rise, so that the rotating assembly 7 enters the cylinder 3. The polyester filaments to be soaked are put into the cylinder 3. The water pumping assembly 8 pumps warm water into the cylinder 3, and at the same time, a cleaning agent is put into the cylinder 3 to start the soaking work of the polyester filaments. During the soaking process, the rotating assembly 7 is started to stir the polyester filaments, so that the cleaning agent can be repeatedly dissolved into the polyester filaments;

[0033] Further refer to Figure 5 , the rotating assembly 7 includes a three-way pipe 72, a round groove 73 is opened in the middle of the upper end of the horizontal part of the L-shaped plate 5, the three-way pipe 72 is fixedly connected with the upper side of the inner surface of the round groove 73, a ball valve 71 is fixedly connected to the upper end of the three-way pipe 72, the air outlet pipe 64 is fixedly connected to the upper side port of the ball valve 71, and a stirring assembly 74 is arranged below the three-way pipe 72;

[0034] Further refer to Figure 6, the stirring assembly 74 includes a hollow round rod 742 which is rotatably connected to the lower side of the inner surface of the round groove 73. The upper side of the outer surface of the hollow round rod 742 is fixedly connected with a driven gear 741 which meshes with the driving gear 655. The lower side of the outer surface of the hollow round rod 742 is fixedly connected with three hollow stirring plates 743 which are all through. The lower ends of the three hollow stirring plates 743 are all fixedly connected with perforated plates 744;

[0035] Further refer to Figure 7 , the water pumping assembly 8 includes a water pump 82 which is fixedly connected to the upper right side of the horizontal part of the L-shaped plate 5. The output end of the water pump 82 is fixedly connected with a delivery pipe 81 which is fixedly connected to the right port of the three-way pipe 72. The input end of the water pump 82 is fixedly connected with a water inlet hose 83.

[0036] The heating plate 63 mentioned above is a mature technical means in the prior art. In this solution, only its function of converting electrical energy into heat energy and setting the heating temperature can be borrowed, and its structure and working principle will not be elaborated here;

[0037] The double-shaft motor 653 mentioned above is a mature technical means in the prior art. In this solution, only its functions of driving two objects to run simultaneously and independently and controlling the rotation speed of the objects can be borrowed, and its structure and working principle will not be elaborated here;

[0038] The ball valve 71 mentioned above is composed of a sphere, a valve seat, a sealing ring, a valve stem and a valve body. It is a mature technical means in the prior art. In this solution, only its function of completely blocking the flow of fluid by rotating the sphere to realize the cutting function of the pipeline can be borrowed, and its structure and working principle will not be elaborated here;

[0039] In specific implementation, use the round plug 41 to block the water outlet pipe 42 so that the water in the cylinder 3 cannot flow out. Put the polyester filaments to be soaked and the cleaning agent into the cylinder 3. Open both electric telescopic rods 2 to extend the piston rods, driving the position of the cylinder 3 to rise, so that the three hollow stirring plates 743 enter the cylinder 3. Put the water inlet hose 83 into warm water, turn on the water pump 82, and pump the warm water into the three-way pipe 72 through the water inlet hose 83 and the delivery pipe 81. At this time, the ball valve 71 is in the closed state. The warm water entering the three-way pipe 72 enters the hollow round rod 742 and the three hollow stirring plates 743, and then flows out through the three hollow stirring plates 743 and into the cylinder 3. In this way, there is no need for manual water addition in the cylinder 3, thus reducing the work burden of the staff, and then start soaking the polyester filaments;

[0040] During the soaking process, start the dual-axis motor 653 to drive the second rotating rod 654 to rotate at a slow speed. The first rotating rod 652 does not rotate, thereby driving the driving gear 655 to rotate. Since the driving gear 655 meshes with the driven gear 741, the rotation of the driving gear 655 drives the driven gear 741 to rotate, thereby driving the hollow circular rod 742 to rotate, and then driving the three hollow stirring plates 743 to rotate, stirring the polyester in the cylinder 3, so that the cleaning agent can be fully dissolved into the polyester filaments, thereby improving the removal effect of the cleaning agent on the impurities in the polyester filaments;

[0041] After the polyester filaments are soaked, start the two electric telescopic rods 2 to contract the piston rods, driving the position of the cylinder 3 to drop, so that the stirring assembly 74 will not obstruct the process of taking out the polyester filaments from the cylinder 3. Take out the polyester filaments in the cylinder 3, take out the round plug 41, drain the water in the cylinder 3, and at the same time clean the remaining impurities in the cylinder 3. The impurities in the water will be intercepted by the filter screen 44 and remain in the second water outlet pipe 43. If it is necessary to clean the impurities in the second water outlet pipe 43, remove the second water outlet pipe 43, process the impurities in the second water outlet pipe 43, and then reinstall the second water outlet pipe 43 back to its original position. This process facilitates the work of cleaning the impurities washed out from the polyester filaments;

[0042] After the water in the cylinder 3 is drained, cover the round plug 41, put the polyester filaments into the cylinder 3, put the inlet hose 83 into the clean water, start the water pump 82, and transport the clean water to the hollow circular rod 742. At the same time, start the dual-axis motor 653 to drive the second rotating rod 654 to rotate, so that the hollow circular rod 742 rotates. The clean water entering the hollow circular rod 742 is sprayed out through the three hollow stirring plates 743 to clean the impurities in the polyester filaments in the cylinder 3. The rotation of the hollow circular rod 742 drives the three hollow stirring plates 743 to rotate, thereby increasing the area of the clean water flushing the impurities in the polyester filaments and improving the flushing effect. After cleaning, take out the polyester filaments from the cylinder 3, drain the water in the cylinder 3, and clean the impurities;

[0043] After the polyester filaments are cleaned, open the ball valve 71, power on the heating plate 63, start the dual-axis motor 653 to drive the first rotating rod 652 and the second rotating rod 654 to rotate, thereby driving the fan blades 651 to rotate, drawing in the external air into the rectangular box 61. The heating plate 63 heats the air in the rectangular box 61. The heated air rises and enters the three-way pipe 72 through the air outlet pipe 64, then enters the hollow circular rod 742, and then comes out through the three hollow stirring plates 743 to dry the polyester filaments. The rotation of the second rotating rod 654 causes the three hollow stirring plates 743 to rotate, thereby increasing the drying area of the hot air and enhancing the drying effect of the drying assembly 6;

[0044] Thus, in the process of texturing polyester filaments, this device can simultaneously meet the requirements of cleaning and drying the polyester filaments. During the subsequent fixed texturing process of the polyester filaments, the drying component 6 can also perform fixed texturing on the polyester filaments. Therefore, this device can complete multiple tasks in the texturing process of polyester filaments, thereby saving production costs.

[0045] It should be particularly noted that the specific installation methods, circuit connection methods, and control methods of the two electric telescopic rods 2, the dual-axis motor 653, and the water pump 82 used in this utility model are all conventional designs, and this utility model will not elaborate on them in detail.

[0046] The working principle of this utility model is as follows:

[0047] Put polyester filaments and cleaning agents into the cylinder 3, turn on the water pump 82 to pump warm water into the cylinder 3, and turn on the dual-axis motor 653 to drive the second rotating rod 654 to rotate, so that all three hollow stirring plates 743 rotate, and stir the polyester filaments during the soaking process.

[0048] After the polyester filaments are soaked, take out the polyester filaments in the cylinder 3, drain the water in the cylinder 3, put the polyester filaments back into the cylinder 3, turn on the water pump 82 to pump clean water into the three hollow stirring plates 743, and then spray it out through the three hollow stirring plates 743 to wash the polyester filaments. At the same time, turn on the dual-axis motor 653 to drive the second rotating rod 654 to rotate, so that all three hollow stirring plates 743 rotate.

[0049] After the polyester filaments are cleaned and the water in the cylinder 3 is drained, turn on the dual-axis motor 653 to drive both the first rotating rod 652 and the second rotating rod 654 to rotate, energize the heating plate 63, the first rotating rod 652 rotates to drive the fan blade 651 to rotate, the heating plate 63 heats the air entering the rectangular box 61, the heated air enters the three hollow stirring plates 743, and comes out through the three hollow stirring plates 743 to dry the polyester filaments in the cylinder 3.
