Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a cotton-like polyester stretching and false-twisting device. Background Technique

[0002] In the textile industry, the processing technology of cotton-like polyester fibers has been continuously developed and innovated. However, the previous cotton-like polyester stretching and false-twisting devices have many deficiencies.

[0003] The traditional devices are often relatively simple in structural design, and there is a lack of effective coordination among various units, resulting in discontinuous fiber processing, easy pauses in intermediate links, and heavy reliance on manual operation. This not only has low efficiency, but also increases labor costs and the risk of operation errors. In terms of transmission, the transmission design of traditional devices is not precise and stable enough, making it difficult to ensure uniform stress during fiber processing, thus affecting the consistency and quality of products. Moreover, its load-bearing capacity is limited and it cannot adapt to high-intensity fiber processing work, restricting the improvement of production capacity. In addition, there is a lack of effective oil storage and oil supply design, and it cannot continuously provide sufficient lubricating oil for rotating components, resulting in serious component wear and short equipment life.

[0004] Therefore, we propose a cotton-like polyester stretching and false-twisting device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a cotton-like polyester stretching and false-twisting device, in order to prevent problems such as discontinuous fiber processing, intermediate pauses, low efficiency, high costs, and high risk of errors caused by relying on manual operation, prevent problems such as inaccurate and unstable transmission, uneven stress affecting product quality, and insufficient load-bearing capacity restricting production capacity, prevent problems such as component wear, short equipment life, and high failure probability affecting production caused by lubrication and maintenance defects, so as to improve the efficiency and quality of fiber processing, reduce production costs, extend the service life of equipment, and ensure the stable progress of production, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A cotton-like polyester stretching and false-twisting device includes a housing, a feeding unit, a stretching and deforming unit, a planetary gear rotating unit and a false-twister. A feeding port is opened in the middle of one end of the housing, and a discharging port is opened in the middle of the other end of the housing away from the feeding port. The feeding unit is arranged outside the housing at one end close to the feeding port, the stretching and deforming unit is arranged inside the housing on one side of the feeding port, the false-twister is arranged inside the housing on one side of the discharging port, and the planetary gear rotating unit is located between the stretching and deforming unit and the false-twister;

[0008] The planetary gear rotation unit includes a central rotating shaft arranged in the middle of one side of the outer shell. One end of the central rotating shaft located outside the outer shell is fixedly connected to a first sun gear, and one end of the central rotating shaft located inside the outer shell is fixedly connected to a second sun gear. An annular T-shaped groove is formed in the inner wall of the outer shell near the second sun gear, and a plurality of planet gear shafts arranged in an annular array are clamped in the annular T-shaped groove. The outer part of the planet gear shaft is fixedly connected to the planet gear. The second sun gear meshes with the planet gear, and the planet gear meshes with the internal gear ring on the inner wall of the outer shell. A first driving motor is fixedly installed on the outer wall of the outer shell near the first sun gear, and a driving wheel is fixedly connected to the outer part of the output shaft of the first driving motor. The driving wheel meshes with the first sun gear;

[0009] A lubricating oil storage cylinder is fixedly installed at the top of the outer shell. A fuel filling port is provided at the top of the lubricating oil storage cylinder. A viewing window is arranged on the outer side of the lubricating oil storage cylinder. A valve is fixedly connected to the outer side of the lubricating oil storage cylinder and directly below the viewing window. One end of the valve away from the lubricating oil storage cylinder is fixedly connected to an oil outlet pipe.

[0010] By adopting the above technical solution, the fiber enters the outer shell from the feeding port, and is first preliminarily guided by the feeding unit. Then, it enters the stretching and deforming unit for stretching and deforming treatment. The first driving motor is started to drive the driving wheel to rotate. The driving wheel meshes with the first sun gear, so that the central rotating shaft rotates, driving the second sun gear to rotate. The second sun gear drives the planet gear meshing with it. The planet gear meshes with the internal gear ring at the same time, realizing the revolution and rotation of the planet gear around the second sun gear. The fiber after the action of the planetary gear rotation unit continues to move forward, reaches the false twister for false twisting treatment, and finally is output from the discharging port;

[0011] During operation, lubricating oil can be added into the lubricating oil storage cylinder through the fuel filling port. The oil quantity in the lubricating oil storage cylinder can be observed through the viewing window. When needed, the valve is opened to make the lubricating oil flow out from the oil outlet pipe to provide lubrication for each rotating wheel.

[0012] Further, the feeding unit includes a support frame. The support frame is fixedly connected to the outer wall of one end of the outer shell, and a plurality of fixing frames arranged in pairs are fixedly connected to the top. Feed guiding rollers are alternately rotatably connected to the inner sides of each pair of fixing frames.

[0013] By adopting the above technical solution, the coordinated rotation of multiple feed guiding rollers guides and preliminarily arranges the fiber, enabling it to smoothly and accurately enter the stretching and deforming unit inside the outer shell and preparing for the subsequent processing procedures.

[0014] Further, the stretching and deforming unit includes stretching rollers, a first deforming guide wheel, a second deforming guide wheel, a third deforming guide wheel, and a fourth deforming guide wheel that are arranged in pairs opposite to each other. The fourth deforming guide wheel is located between one set of stretching rollers and is offset to one side. The first deforming guide wheel and the second deforming guide wheel are located between adjacent pairs of stretching rollers. The third deforming guide wheel is located between one set of stretching rollers and the planetary gear rotating unit.

[0015] By adopting the above technical solution, when the fiber passes through one set of stretching rollers, the fourth deforming guide wheel located between this set of stretching rollers and offset to one side starts to guide the fiber to generate preliminary deformation. Between adjacent pairs of stretching rollers, the first deforming guide wheel and the second deforming guide wheel further change the deformation path of the fiber, while the third deforming guide wheel adjusts and guides the deformation of the fiber again between one set of stretching rollers and the planetary gear rotating unit, preparing for the subsequent entry into the planetary gear rotating unit.

[0016] Further, a plurality of vertically and equidistantly arranged lead screws are rotatably connected to one side of the outer shell. A limiting rod corresponding to the position and quantity of the lead screws is fixedly connected to the other side of the outer shell. Two sets of relatively output thread grooves are provided on the outer side of the lead screw. Threaded blocks are threadedly connected to the outside of the two sets of thread grooves. A limiting block is slidably connected to the outside of the limiting rod.

[0017] By adopting the above technical solution, since two sets of relatively output thread grooves are provided on the outer side of the lead screw, when the lead screw rotates, the threaded blocks threadedly connected to the outside of the thread grooves will move relatively or away from each other along the lead screw. At the same time, on the limiting rod corresponding to the position and quantity of the lead screw, the slidably connected limiting block plays a role in limiting and guiding, ensuring that the threaded blocks and the related components can move smoothly and accurately to achieve the required functions.

[0018] Further, a second driving motor is fixedly installed at the top of the outer shell. The output shaft of the second driving motor penetrates the outer shell and is fixedly connected to the top of the lead screw. The stretching roller is rotatably connected between the threaded block and the limiting block.

[0019] By adopting the above technical solution, since the stretching roller is rotatably connected between the threaded block and the limiting block, when the lead screw rotates, the threaded block moves along the lead screw and drives the connected stretching roller to move at the same time, thereby realizing the adjustment of the distance between the stretching rollers to meet different stretching requirements.

[0020] Further, four support legs are fixedly installed at the bottom of the outer shell. The four support legs are arranged in two pairs symmetrically.

[0021] By adopting the above technical solution, the four support legs are stably placed on the working plane, providing firm support for the entire device, ensuring that the device remains balanced and stable during operation, without being affected by external factors to cause shaking or displacement, thereby ensuring that the device can normally and effectively carry out the stretching, deformation and false twisting work of fibers.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] (1) For the stretching, deformation and false twisting device of cotton-like polyester of the utility model, through the coordinated work of the feeding unit, stretching and deformation unit, planetary gear rotation unit and false twister, the continuous and automatic fiber processing is realized, the pauses in the intermediate links and manual intervention are reduced, and the production efficiency is greatly improved.

[0024] (2) For the stretching, deformation and false twisting device of cotton-like polyester of the utility model, the layout of the planetary gears and the meshing design with the sun gear and internal gear ring can provide an accurate and stable transmission ratio, ensure uniform force on the fibers during processing, thereby improving the consistency and quality of the products; the common action of multiple planetary gears effectively disperses the load, enabling the device to withstand greater tensile force and torque and adapt to the high-strength fiber processing requirements.

[0025] (3) For the stretching, deformation and false twisting device of cotton-like polyester of the utility model, the oil storage cylinder can store sufficient lubricating oil, provide continuous lubrication for each rotating part in the device, reduce the wear between parts, and extend the service life of the equipment; the visual window on the oil storage cylinder is convenient for the operator to directly observe the oil volume and replenish the lubricating oil in time. At the same time, the design of the valve and the oil outlet pipe makes the oil filling operation simple and controllable, which is helpful for the daily maintenance and stable operation of the equipment.

[0035] During use, fibers enter the outer shell 1 from the feed port 21. First, they are initially guided by the feed unit 2, and then enter the stretching and deforming unit 3 for stretching and deforming treatment. The first driving motor 11 is started to drive the driving wheel 12 to rotate. The driving wheel 12 meshes with the first sun gear 6, so that the central rotating shaft 5 rotates, driving the second sun gear 7 to rotate. The second sun gear 7 drives the planetary gear 8 meshing with it. The planetary gear 8 meshes with the internal gear ring at the same time, realizing the revolution and rotation of the planetary gear 8 around the second sun gear 7. The fibers after the action of the planetary gear rotation unit 4 continue to move forward, reach the false twister 30 for false twisting treatment, and finally are output from the discharge port 22;

[0036] During operation, lubricating oil can be added into the storage oil cylinder 13 through the oil filling port 14. The oil quantity in the storage oil cylinder 13 can be observed through the visual window 15. When needed, the valve 16 is opened to make the lubricating oil flow out from the oil outlet pipe 17 to provide lubrication for each rotating wheel.

[0037] Exemplarily, as Figure 1 、 Figure 2 shown, the present invention further includes that the feed unit 2 includes a support frame 18.

[0038] During use, the coordinated rotation of multiple feed guide rollers 20 guides and preliminarily arranges the fibers, enabling them to smoothly and accurately enter the stretching and deforming unit 3 inside the housing 1, preparing for subsequent processing operations.

[0039] Exemplarily, as Figure 1 , Figure 2 shown, the present utility model further includes that the stretching and deforming unit 3 includes stretching rollers 25 arranged in pairs opposite to each other, a first deforming guide wheel 27, a second deforming guide wheel 28, a third deforming guide wheel 29, and a fourth deforming guide wheel 33.

[0040] During use, when the fibers pass through one set of stretching rollers 25, the fourth deforming guide wheel 33 located between this set of stretching rollers 25 and offset to one side starts to guide the fibers to produce preliminary deformation. Between adjacent pairs of stretching rollers 25, the first deforming guide wheel 27 and the second deforming guide wheel 28 further change the deformation path of the fibers, while the third deforming guide wheel 29 adjusts and guides the deformation of the fibers again between one set of stretching rollers 25 and the planetary gear rotating unit 4, preparing for subsequent entry into the planetary gear rotating unit 4.

[0041] Exemplarily, as Figure 1 , Figure 2 , Figure 4 shown, the present utility model further includes that multiple vertical and equidistantly arranged lead screws 23 are rotatably connected to one side of the housing 1, and a limiting rod 32 corresponding to the position and quantity of the lead screws 23 is fixedly connected to the other side of the housing 1. Two sets of relatively output thread grooves are provided on the outer side of the lead screw 23, and sliders 24 are threadedly connected to the outside of both sets of thread grooves. A limiting block 34 is slidably connected to the outside of the limiting rod 32.

[0042] During use, since two sets of relatively output thread grooves are provided on the outer side of the lead screw 23, when the lead screw 23 rotates, the sliders 24 threadedly connected to the outside of the thread grooves will move relatively or away from each other along the lead screw 23. At the same time, on the limiting rod 32 corresponding to the position and quantity of the lead screw 23, the slidably connected limiting block 34 plays a role in limiting and guiding, ensuring that the sliders 24 and related components can move smoothly and accurately to achieve the required functions.

[0043] Exemplarily, as Figure 1 , Figure 2 , Figure 4As shown, the present utility model further includes that a second driving motor 26 is fixedly installed at the top end of the outer shell 1.

[0044] During use, since the stretching roller 25 is rotatably connected between the slider 24 and the limiting block 34, when the lead screw 23 rotates, the slider 24 moves along the lead screw 23, and at the same time drives the connected stretching roller 25 to move, thereby realizing the adjustment of the distance between the stretching rollers 25 to meet different stretching requirements.

[0045] Exemplarily, as Figure 1 、 Figure 2 As shown, the present utility model further includes that four support legs 31 are fixedly installed at the bottom of the outer shell 1, and the four support legs 31 are arranged in a pairwise symmetrical manner.

The lubricating oil amount in the oil storage cylinder 13 is observed through the viewing window 15, and lubricating oil is added through the oil filling port 14 when necessary;

[0048] The fibers to be processed are fed into the device from the feeding port 21. Through the coordinated rotation of multiple feeding guide rollers 20 in the feeding unit, the fibers are guided and preliminarily sorted, so that they enter the stretching and deforming unit 3 smoothly and accurately;

[0049] The fibers enter the stretching and deforming unit 3 and are stretched by the stretching rollers 25 arranged in pairs. The fourth deforming guide wheel 33 guides the fibers to generate preliminary deformation between one group of stretching rollers 25. The first deforming guide wheel 27 and the second deforming guide wheel 28 further change the fiber deformation path between adjacent stretching rollers 25. The third deforming guide wheel 29 further adjusts and guides the fiber deformation between the stretching rollers 25 and the planetary gear rotating unit 4. According to the processing effect and fiber characteristics, if it is necessary to adjust the distance between the stretching rollers 25, it is realized by driving the lead screw 23 to rotate through the second driving motor 26, so that the slider 24 and the connected stretching roller 25 move;

[0050] The first driving motor 11 drives the driving wheel 12 to rotate, and through the first sun gear 6 and the central rotating shaft 5, the second sun gear 7 rotates, thereby driving the planetary gear 8 to revolve and rotate around the second sun gear 7 to perform corresponding processing on the fibers;

[0051] The fiber after being acted upon by the planetary gear rotating unit 4 continues to advance and reaches the false twister 30 for false twisting treatment;

[0052] The fiber that has completed the false twisting treatment is finally output from the discharge port 22.
