Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a novel yarn pressing roller structure. Background Technology

[0002] The yarn pressure roller is an important component in textile machinery. It is mainly used to control the tension, position and movement trajectory of the yarn to ensure the stability and precision of the weaving or embroidery process.

[0003] Chinese Patent CN210287667U discloses a pressure roller mechanism for a warping machine drafting device. The drafting device is a three-roller type, consisting of a pressure roller, bearing, bearing housing, brake, slider, slide rail, cross arm, cylinder, cylinder seat, limiting angle iron, limiting bolt, and locking nut. When the pressure roller rises, the cylinder pushes the cross arm, causing the slider on the bearing housing and the pressure roller to move upwards along the slide rail. When the pressure roller descends, the cylinder causes it to move downwards, pressing against the two drafting rollers. The yarn passes between the contact surfaces of the pressure roller and the two drafting rollers. During drafting, the two actively rotating drafting rollers frictionally drive the pressure roller to rotate, clamping and pulling out the yarn. The lowering position of the pressure roller can be adjusted by adjusting the limiting bolt and locking nut. When the machine stops, the brake on the pressure roller engages. This mechanism is compact, simple in structure, easy to adjust, economical, and practical, further improving the quality of warping.

[0004] The yarn pressing roller structure in textile machinery under the above scheme and existing technology is usually a single solid steel roller inserted into the bearing seat. When the yarn pressing roller rotates and presses yarn, friction will cause the surface temperature of the yarn pressing roller to rise. When the temperature is too high, it will reduce the service life of the yarn pressing roller and affect the quality of the yarn. There is a lack of a new type of yarn pressing roller structure that can actively cool down, which needs to be improved and optimized. Utility Model Content

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-7 The present invention provides the following two preferred embodiments:

[0024] Example 1: A novel yarn pressing roller structure includes a bearing housing 1, which consists of two symmetrically arranged sets.

A composite yarn pressing roller body 3 is fixedly connected to one end of the hollow rotating shaft 2, and a sealed bearing 4 is fixedly connected to the other end of the hollow rotating shaft 2. A water inlet tank 5 is fixedly inserted into the middle of one set of sealed bearings 4, and a water outlet tank 6 is fixedly inserted into the middle of the other set of sealed bearings 4. A support plate 7 is fixedly connected to one end of the bearing housing 1, and two sets of safety locking components are symmetrically arranged at one end of the support plate 7. The composite yarn pressing roller body 3 includes a ceramic wear-resistant layer 301, and a stainless steel support is fixedly connected to the inner side of the ceramic wear-resistant layer 301. The heat dissipation layer 302 is supported by a stainless steel heat dissipation layer 302, and a water storage cavity 303 is provided inside the layer. The support plate 7 has a limiting groove 11 in the middle, and two sets of slots 12 are symmetrically provided at one end of the limiting groove 11. Two sets of pin grooves 13 are symmetrically provided at one end of the support plate 7, and a threaded hole 14 is provided at one end of the pin groove 13. The water inlet tank 5 has a water inlet pipe 9 at one end, and the water inlet tank 5 is inserted into one set of limiting grooves 11. Two sets of pins 15 are symmetrically fixedly connected at one end of the water inlet tank 5. The water outlet tank 6 has a water outlet pipe 10 at one end, and the water outlet tank 6 is inserted into another set of limiting grooves 11. Two sets of pins 15 are symmetrically fixedly connected at one end of the water outlet tank 6. A locking hole 16 is provided in the middle of the pin 15.

[0025] In use, the hollow rotating shafts 2 at both ends of the composite pressing roller body 3 are respectively inserted into the bearing seats 1 at both ends, and the bearing seats 1 are installed and fixed on the spinning machinery. The water inlet tank 5 and the water outlet tank 6 are respectively inserted into the limiting grooves 11 of the support plates 7 on the bearing seats 1 at both ends. The two sets of pins 15 at one end of the water inlet tank 5 and the water outlet tank 6 are respectively inserted into the corresponding slots 12, and the locking holes 16 on the pins 15 are sequentially inserted and fixed by the safety locking components. The composite pressing roller body 3 is composed of three layers: a ceramic wear-resistant layer 301, a stainless steel support and heat dissipation layer 302, and a water storage cavity 303. The ceramic wear-resistant layer 301 has a surface The wear resistance of the layer and the stainless steel support heat dissipation layer 302 support and transfer frictional heat to the water storage cavity 303, which improves the service life. After installation, cold water is put into the water inlet pipe 9 at one end of the water inlet tank 5. The frictional heat is absorbed by the cold water in the water storage cavity 303. After a period of use, the hot water is discharged by opening the water outlet pipe 10 at one end of the water outlet tank 6. Then, cold water is injected again from the water inlet pipe 9 of the water inlet tank 5 to continue to cool down the pressing roller equipment. When the composite pressing roller body 3 rotates, the sealed bearings 4 in the hollow rotating shaft 2 at both ends of the composite pressing roller body 3 keep the water inlet tank 5 or the water outlet tank 6 connected to the hollow rotating shaft 2 for rotation.

Springs 802 are symmetrically fixedly connected to both ends of the middle part of the locking pin 801, and one end of the spring 802 is fixedly connected to the inner wall of the pin groove 13.

[0027] In use, when the pin 15 is inserted into the slot 12, one end of the locking pin 801 in the pin slot 13 is first pressed into the protective nut 803, and then the other end of the locking pin 801 is inserted into the locking hole 16. The spring 802 connected in the middle of the locking pin 801 is used to press the locking pin 801 into the locking hole 16. The protective nut 803 is threaded into the threaded hole 14 to protect the locking pin 801 and prevent it from being accidentally pulled out. The locking hole 16 loosens the inlet tank 5 and outlet tank 6 within the limiting groove 11. When it is necessary to disassemble the inlet tank 5 or outlet tank 6, simply turn the protective nut 803 out of the threaded hole 14 in sequence, and then pull the protective nut 803 outward at the same time to pull the locking pin 801 out of the locking hole 16. Then pull the inlet tank 5 and outlet tank 6 outward. The protective nut 803 rotates and engages with the locking pin 801, so that the protective nut 803 rotates while the locking pin 801 is not affected.
