Description

Technical Field

[0001] The utility model relates to the technical field of viscose spinning equipment, in particular to a drying device for a wet spinning machine which is easy to maintain. Background Art

[0002] A spinning machine is a machine that forms filaments from a fiber-forming polymer solution or melt. Depending on the fiber spinning method, spinning machines are divided into three types: wet spinning machines, melt spinning machines, and dry spinning machines.

[0003] Continuous spinning is currently the primary development direction for viscose filament yarn. Its main advantage lies in integrating spinning, washing, drying, and forming into a single machine, resulting in high spinning speeds, a short production process, and easy process control. Where spinning conditions permit, continuous spinning can produce large, jointless bobbins weighing over 5 kg, effectively improving the production efficiency of downstream customers.

[0004] Normally, each zone of a continuous spinning machine is composed of a group of pairs of rollers consisting of multiple small processing rollers and one large processing roller. The large processing roller and the small processing roller have a certain angle (the main purpose is to allow the silk thread to automatically move toward the winding surface). After the silk thread passes through the post-coagulation area, elution area, sizing area and drying area, the silk thread forming, washing, oiling and drying processes are completed. After drying, the silk thread passes through the wire guide plate, vertical rod wheel, tension wheel, porcelain nozzle and other process parts. The friction between the paper tube and the winding machine drives the paper tube to rotate, and the silk thread is wound around the paper tube to finally form a silk tube.

[0005] Currently, the drying unit in the spinning machine's drying area is integrated into a drying panel, which is then connected to mounting panels on the columns on either side of the spinning machine frame via flange bolts. Maintenance of the drying unit requires disassembling the flanges, removing the panel and dryer from the columns, and then transporting the entire unit (drying panel and dryer) to the maintenance room for repair. This entire process is labor-intensive and time-consuming, impacting on-site production schedules. Summary of the Invention

[0006] In order to solve the problems and shortcomings in the above-mentioned prior art, the utility model proposes a drying device for a wet spinning machine that is easy to maintain. The drying device can be repaired on site and does not need to be disassembled and then transported, which significantly reduces the labor intensity of on-site workers.

[0007] In order to achieve the above-mentioned purpose of the invention, the technical solution of the present utility model is as follows:

[0008] The utility model proposes a drying device for a wet spinning machine that is easy to maintain. The drying device is arranged in the drying area of ​​the spinning machine, and includes a drying panel and a dryer arranged on the drying panel.

[0012] Preferably, the synchronization mechanism is a pulley mechanism.

[0013] Preferably, the synchronization mechanism is a sprocket chain mechanism.

[0014] Beneficial effects of the utility model:

[0015] 1. The drying device of the present invention enables on-site maintenance of the dryer, eliminating the need to disassemble the dryer and then transport it to a maintenance room for repair. Furthermore, after the maintenance is complete, the drying device does not need to be transported to the production site for assembly. Therefore, the present invention significantly reduces the labor intensity of on-site workers, significantly saves maintenance time, and improves maintenance efficiency.

[0016] 2. The utility model significantly reduces the number of times the drying device is moved, thereby reducing wear on the drying device and extending its service life.

[0017] 3. The two drying rollers of the dryer of the utility model are connected to the same driving power source through a synchronization mechanism, which ensures the synchronization of the movement of the drying rollers and avoids the accumulation of silk strips and uneven drying.

[0018] 4. The drying roller of the present invention is connected to the power source through a transmission mechanism, which reduces the transmission ratio between the motor and the drying roller, thereby preventing the motor from being burned due to excessive load.

[0019] 5. The motor output end of the utility model is provided with a coupling. When the angle of the drying roller needs to be adjusted due to process requirements, the extension and tightening of the coupling can cooperate with the drying roller to adjust the angle.

[0027] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will further illustrate the technical solutions for achieving the purpose of the present invention through several specific embodiments. It should be noted that the technical solutions claimed for protection by the present invention include but are not limited to the following embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1

[0029] This embodiment discloses a drying device for a wet spinning machine that is easy to maintain. Figure 1As shown, the drying device 1 is arranged in the drying area of ​​the wet spinning machine. After the filaments are formed, oiled, rinsed and other processes at the front end of the spinning machine, the filaments are transported to the drying device 1 in the drying area by the wire guide device for drying. The drying device 1 consists of a drying panel 2 and a dryer 3 arranged on the drying panel 2. The drying panel 2 is fixed on the mounting panel of the frame column 4. The two ends of the mounting panel are respectively fixedly connected to the frame columns 4 on both sides. The drying panel 2 is fixedly connected to the mounting panel by flange bolts; further, a first fixed plate 5 is provided on the drying panel 2, a second fixed plate 6 is provided on one of the frame columns 4, and a connecting rod mechanism 7 is provided between the first fixed plate 5 and the second fixed plate 6. The connecting rod mechanism 7 includes a first connecting rod 701 and a second connecting rod 702 that are rotatably connected to each other by a first rotating pin. The other end of the first connecting rod 701 is rotatably connected to the first fixed plate 5 by a second rotating pin, and the other end of the second connecting rod 702 is rotatably connected to the second fixed plate 6 by a third rotating pin.

[0030] In the embodiment depicted in this utility model, after exiting the spinning machine's spinneret, the filaments first pass through a forming tube and are drawn onto a pair of processing rollers, where they are pulled and lifted. The processing rollers are divided into a forming zone, an oiling zone, and a rinsing zone. After being drawn by the processing rollers, the filaments pass through the forming zone, the oiling zone, and the rinsing zone in sequence. They then pass through a guide wire device and are drawn to the dryer 3 of the drying apparatus 1 for drying. They are then wound into bobbins on a small loom.

[0031] When the drying device 1 breaks down and needs to be repaired, the drying panel 2 is usually removed from the mounting panel of the frame column 4, and the dryer 3 is removed together. Then the entire drying device 1 is moved to a maintenance room or other maintenance point for repair. After the repair is completed, the drying device 1 is restored and assembled on the mounting panel. In the solution described in the present utility model, under the action of the connecting rod mechanism 7, when the bolts between the drying panel 2 and the mounting panel are removed, the connecting rod mechanism 7 will first support the drying device 1, and then under the transmission action of the connecting rod mechanism 7, the entire drying device 1 can be pushed outward from between the two side columns, as shown in FIG. Figure 3 As shown, the drying device 1 is suspended on the connecting rod mechanism 7, and there is no obstruction from the installation panel and the frame column 4, so the drying device 1 can be suspended and repaired in situ. After the repair is completed, the drying device 1 is reset to the installation panel by relying on the connecting rod mechanism 7, and then the drying device 1 is locked and fixed to the installation panel with bolts, as shown in FIG. Figure 2 shown.

[0032] The entire maintenance process described above does not involve the transportation or lifting of the drying device 1, which can significantly reduce the labor intensity of on-site workers, significantly save maintenance time, and improve maintenance efficiency. In addition, it can also significantly reduce the wear and tear on the drying device 1 caused by the transportation process, thereby extending the service life of the drying device.

[0033] It can be understood that, under normal circumstances, the first fixed plate 5 provided on the drying panel 2 is located on the side close to the second fixed plate 6, so that the connecting rod mechanism 7 will not collide with the parts on the drying panel 2, hinder its movement, and affect the maintenance of the parts on the panel; and it can also ensure that the entire drying device 1 can be moved out from the gap between the two columns on the left and right sides, so that maintenance can be smoothly carried out.

[0034] Example 2

[0035] This embodiment discloses a drying device for a wet spinning machine that is easy to maintain. Based on the embodiment 1, Figure 4 As shown, the dryer 3 includes a first drying roller 302 and a second drying roller 303 arranged side by side on the drying panel 2, the rotating shaft of the first drying roller 302 is connected to the first transmission mechanism 9, and the rotating shaft of the second drying roller 303 is connected to the second transmission mechanism 10, and the first transmission mechanism 9 and the second transmission mechanism 10 are respectively connected to the power source 301.

[0036] The silk thread is drawn onto the drying rollers through a wire guide, then wound onto the drying rollers in the drying area for drying. Finally, it is wound into a roll on a small loom. As you can see, the drying rollers have steam-water circulation channels inside, which circulate steam and water to maintain the required drying temperature. Furthermore, to ensure effective drying, the drying rollers are typically constructed of materials with good thermal conductivity, such as stainless steel.

[0037] In the embodiment described in the present invention, the power source 301 can be a component that can drive the drying roller to rotate, such as a servo motor, a hydraulic motor, etc. The power source 302 itself does not belong to the innovative improvement of the present invention and will not be described in detail here.

[0038] In the embodiment depicted in the present invention, the transmission mechanism serves as an intermediate connecting component between the drying roller and the power source. Since the transmission mechanism can reduce the transmission ratio between the drying roller and the motor, compared with the motor directly driving the drying roller, the motor will not be burned due to heavy load, thereby extending the service life of the motor.

[0039] It can be understood that the first transmission mechanism 9 and the second transmission mechanism 10 usually adopt a pulley mechanism, which is fixed on the drying panel. The output end of the motor is connected to one of the pulleys, and the other pulley is connected to the rotating shaft of the drying roller. A belt is tensioned between the two pulleys.

[0040] Example 3

[0041] This embodiment discloses a drying device for a wet spinning machine that is easy to maintain. Based on Example 2, the first transmission mechanism and the second transmission mechanism further include a coupling 11 respectively. One end of the pulley mechanism of the first transmission mechanism is connected to the rotating shaft of the first drying roller, and the other end is connected to the coupling 11, and then the coupling 11 is connected to the power source 301. Similarly, one end of the pulley mechanism of the second transmission mechanism is connected to the rotating shaft of the second drying roller, and the other end is connected to the coupling 11, and then the coupling 11 is connected to the power source 301.

[0042] In the actual production process, the angle of the drying roller may be adjusted and changed according to the process requirements. Therefore, a coupling is specially configured to connect the drying roller to the power source. By extending and tightening the coupling 11, the angle can be adjusted to smoothly realize the drive rotation of the drying roller.

[0043] Example 4

[0044] This embodiment discloses a drying device for a wet spinning machine that is easy to maintain. Based on the above-mentioned embodiment 2 or embodiment 3, in order to ensure the synchronization of the movement of the two drying rollers and avoid the accumulation of silk strips on the rollers and uneven drying of the silk strips, the input ends of the first transmission mechanism 9 and the second transmission mechanism 10 are connected to the output ends of the same power source 301 through a synchronization mechanism 8, and the two drying rollers are driven by the same motor to ensure the synchronization of the movement.

[0045] It is understandable that the synchronization mechanism 8 can be a pulley mechanism or a sprocket chain mechanism, but considering that the chain drive is prone to tooth jumping when moving at high speed, and in various situations such as requiring accurate transmission ratio, harsh working environment, large power transmission and medium speed, requiring certain overload protection capabilities, and usage costs, it is given priority to use a pulley mechanism as the synchronization mechanism 8.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention falls within the scope of protection of the present invention.
