Description

Technical Field

[0001] This utility model relates to the field of spinning machine roller system adjustment technology, specifically to an independent roller system adjustment device for a continuous spinning machine. Background Technology

[0002] Currently, in continuous spinning machines, multiple small rollers are typically installed above the main drum to guide the winding and transport of the filament on the drum. Existing spinning machines generally adopt a fixed roller layout structure, that is, four small rollers are installed above the main drum in a fixed position. Because the positions of the small rollers are not adjustable, the path, angle, and winding circumference of the filament between the small rollers and the main drum vary.

[0003] These differences directly affect key aspects of the continuous spinning process. For example: 1. The different contact time and angle between different filaments and the coagulation liquid are not consistent, which can easily cause uneven fiber coagulation; 2. In the washing process, the degree of contact between the yarn and the washing solution varies, which may result in uneven residue of impurities; in the oiling process, the amount of oil adhering to the surface of different yarns varies, which affects the frictional properties of the subsequent fibers. 3. During the drying process, it is difficult to maintain a consistent number of wraps and distribution density of the yarn on the drum, resulting in uneven drying of the yarn, leading to either over-drying or under-drying.

[0004] Therefore, existing spinning machines with fixed small rollers have difficulty achieving consistent processing of multiple filaments under the same process conditions, which can easily lead to differences in fiber properties and affect product quality and production stability.

[0005] Currently, some technologies have attempted to improve process consistency by changing the diameter of the small rollers or adjusting the speed of the large drum. However, these methods only partially alleviate the problem and still cannot achieve independent and precise adjustment of each roller system. Therefore, existing technologies lack a structure capable of flexibly adjusting the position and angle of the small rollers to adapt to different spinning varieties and process requirements. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide an independent adjustment device for the roller system of a continuous spinning machine. This utility model can improve the processing effect of filaments in multiple steps such as coagulation, washing, oiling and drying. In the coagulation stage, by adjusting the angle of the roller system to change the contact state between the filaments and the coagulation liquid, more uniform coagulation can be ensured and the initial quality of the fiber can be improved, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an independent adjustment device for the roller system of a continuous spinning machine, comprising a screw fixing block, a screw, a small roller slider, a slider fixing block adjusting nut, a flat-headed tapered bolt, a small roller, a spinning arm, a large drum, and a drum shaft. The screw fixing block is installed on the spinning arm, and the screw is disposed on the side of the spinning arm. The screw is fixedly connected to the screw fixing block. The small roller is disposed between the spinning arms. One of the spinning arms has an elongated hole extending along its length. The small roller slider passes through the elongated hole and can slide along the elongated hole. The screw is a transmission component, cooperating with the screw to achieve position adjustment. The small roller slider is fixedly connected to the slider fixing block adjusting nut, and the slider fixing block adjusting nut is threadedly connected to the screw. The slider fixing block adjusting nut and the screw are threadedly engaged. After the holiday, the small roller slider is used to axially lock the slider to prevent displacement under equipment vibration. The slider is fixed by adjusting the position of the slider fixing block adjusting nut on the lead screw. Specifically, the slider fixing block adjusting nut is sleeved on the lead screw and used to lock the position of the small roller slider after adjustment, thereby realizing the linear position adjustment of the small roller along the long hole. The two ends of the small roller are respectively provided with spherical bearings. The spherical bearings and the small roller slider are connected to the spherical bearings by flat-head tapered bolts. The spherical bearings allow the horizontal angle of the small roller to be adjusted independently. The flat-head tapered bolts serve as a connection and fastening function. The spherical bearings, small roller slider, small roller, and flat-head tapered bolts constitute the roller system components, which participate in the yarn winding and conveying. The spinning arm is the support structure. The large drum is installed on the drum shaft, and the two ends of the drum shaft are respectively connected to the spinning arm. The screw drives the small roller slider to move in the long hole, which, together with the joint bearing, rotates the small roller, forming a dual adjustment mechanism of "linear position adjustment + horizontal angle adjustment" to achieve independent adjustment of each roller system relative to the large drum.

[0008] Furthermore, a large drum is installed at the lower end of the spinning arm, and a crossbeam is installed at the upper end of the spinning arm, thus forming a complete support structure.

[0009] Furthermore, the lead screw is made of alloy steel, which has good corrosion resistance and structural stability, thereby improving transmission strength and dimensional stability.

[0010] Furthermore, the small roller slider is made of stainless steel, and its sliding surface in contact with the elongated hole is polished, which reduces friction and improves corrosion resistance.

[0011] Furthermore, several small rollers and corresponding small roller sliders are provided above the large drum. The surface of the small rollers is coated with an anti-slip and wear-resistant coating. Each small roller can be independently adjusted by a corresponding lead screw and a spherical bearing, thereby changing the number of turns and distribution density of the corresponding filaments on the large drum. The spherical bearing is a self-lubricating spherical bearing, which allows the small rollers to rotate flexibly around the small roller slider to adjust the horizontal angle.

[0012] Furthermore, the fabric-coated boom is made of ductile iron, which has high strength, high toughness, and good shock absorption performance.

[0013] Furthermore, the flat-head tapered bolts are made of high-strength stainless steel and have undergone surface hardening treatment to improve connection strength and anti-loosening performance.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms a dual adjustment mechanism of "position sliding + angle rotation" through the coordinated operation of the lead screw, small roller slider, joint bearing and long hole of the spinning arm; this structure can realize independent and precise adjustment of the angle of each roller system, effectively overcoming the defects of the existing fixed small roller layout that cannot be flexibly adjusted; thus, it can carry out differentiated process control for different varieties and deniers of regenerated cellulose fibers, and improve the adaptability of the spinning machine in multiple process scenarios.

[0015] 2. This invention improves the processing effect of filaments in multiple steps such as coagulation, washing, oiling, and drying. In the coagulation stage, adjusting the roller system angle changes the contact state between the filaments and the coagulation liquid, ensuring more uniform coagulation and improving the initial quality of the fibers. In the washing stage, an appropriate roller system angle allows the filaments to fully unfold and come into full contact with the washing liquid, thereby improving the cleanliness of the wash. In the oiling stage, precise angle control ensures that the oil adheres evenly to the surface of the filaments, enhancing the lubrication performance and anti-friction ability of the fibers. In the drying stage, by independently adjusting the angle between the small roller and the large drum, the number of winding turns and the distribution density of the filaments on the large drum can be flexibly changed: when producing coarse denier filaments, reducing the angle increases the number of winding turns and extends the drying time to ensure sufficient evaporation of moisture; when producing fine denier filaments, increasing the angle reduces the number of winding turns to prevent the fibers from becoming brittle due to over-drying.

[0016] 3. In terms of material selection, this utility model adopts high-performance components such as stainless steel small roller sliders and ductile iron spinning arms, which improves the overall strength, corrosion resistance and service life of the device. Through the above structural design and material application, the device not only improves the quality stability and production efficiency of regenerated cellulose fibers, but also meets the diversified process requirements of different spinning varieties, and has high promotion and application value.

[0020] Please see Figure 1-3 This utility model provides a technical solution: an independent adjustment device for the roller system of a continuous spinning machine, including a screw fixing block 1, a screw 2, a small roller slider 3, a slider fixing block adjusting nut 4, a flat-head tapered bolt 5, a small roller 6, a spinning arm 7, a large drum 8, a crossbeam 9, a drum shaft 10, a joint bearing 11, and an elongated hole 12.

[0021] The lead screw fixing block 1 is installed on the spinning arm 7 to fix the lead screw 2; the lead screw 2 is threadedly connected to the small roller slider 3, and the rotational motion is converted into the linear motion of the small roller slider 3; the spinning arm 7 has an elongated hole 12, the small roller slider 3 is embedded in the elongated hole 12 and can slide along the direction of the elongated hole 12, and its end is connected to the small roller 6 by a flat-headed tapered bolt 5; the slider fixing block adjusting nut 4 is sleeved on the end of the lead screw 2 to lock its position after the position of the small roller slider 3 is adjusted; the small roller 6 and the small roller slider 3 are connected by a joint bearing 11, and the small roller 6 is set parallel to the large drum 8 to guide the winding path of the yarn on the large drum 8; the spinning arm 7 is an integral support structure, and the large drum 8 is installed by a drum shaft 10 and supported by a crossbeam 9, and then driven to rotate by a drive mechanism to realize the transmission and drying of the yarn.

[0022] In practice, the lead screw 2 is made of alloy steel and, after heat treatment, possesses high strength and precision, ensuring it is not easily deformed during long-term transmission and maintaining the adjustment accuracy of the small roller slider 3. The small roller slider 3 is made of stainless steel, and its sliding surface in contact with the elongated hole 12 on the spinning arm 7 is polished to reduce the coefficient of friction and improve corrosion resistance in humid and chemically-containing environments. The flat-head tapered bolt 5 is made of high-strength stainless steel and undergoes surface hardening treatment. Its tapered head is compatible with the connection hole of the small roller 6, and the pre-tightening force can eliminate the connection gap, preventing the small roller 6 from shaking during operation. The spinning arm 7 is made of ductile iron and undergoes aging treatment to eliminate internal stress. Its surface is painted to enhance rust resistance, stably supporting various components and withstanding the tension during yarn winding. The surface of the small roller 6 is coated with a ceramic anti-slip and wear-resistant coating with a thickness of 0.05–0.1 mm. This coating ensures frictional stability when in contact with the yarn and improves wear resistance, thereby extending its service life.

[0023] The working principle of this utility model is as follows: In use, according to the type of regenerated cellulose fiber, such as coarse denier or fine denier filament and process requirements, firstly, by rotating the screw 2, the small roller slider 3 slides along the elongated hole 12 of the spinning arm 7, changing the relative position of the small roller 6 and the large drum 8; then, using the joint bearing 11 between the small roller 6 and the small roller slider 3, the horizontal angle of the small roller 6 is finely adjusted; when producing coarse denier filament and needing to enhance the drying effect, the screw 2 is rotated to move the small roller 6 closer to the large drum 8, and the angle of the small roller 6 is appropriately adjusted to reduce the included angle between the small roller 6 and the large drum 8, thereby increasing the number of turns of the filament on the large drum 8 and extending the drying time; when producing fine denier filament and needing to avoid over-drying, the screw 2 is rotated in the opposite direction to move the small roller 6 away from the large drum 8, and the angle of the small roller 6 is adjusted to increase the included angle between the small roller 6 and the large drum 8, thereby reducing the number of turns of the filament; after completing the position and angle adjustment, the adjusting nut 4 of the slider fixing block is tightened to lock the position of the small roller slider 3.

[0024] During the spinning process, the filaments are wound around the large drum 8 under the guidance of the small roller 6, and the drying and other processes are completed as the large drum 8 rotates. At the same time, for the roller system of processes such as solidification, washing, and oiling, the angle and position of the small roller 6 can be adjusted in the same way to ensure that the process conditions of each stage match the fiber characteristics.

[0025] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
