Description

Technical Field

[0001] This application relates to the field of spinning manufacturing technology, specifically to an adjustable pre-networker for a spinning machine. Background Technology

[0002] In the chemical fiber spinning process, after the filament bundles ejected from the spinning spinneret undergo oiling, drafting, and other processes, they need to be networked to increase the strength of the filaments. Nowadays, air jetting is generally used to mix filaments and staple fiber yarns for network processing, so that they generate cohesion and form a series of continuous and evenly distributed network knots, thereby replacing the traditional twisting and sizing. This method has been widely used, and the pre-networker is one of the various networkers in chemical fiber textile machinery parts.

[0003] An existing patent (publication number: CN217536278U) discloses an adjustable device for a spinning pre-networker, which includes a base, an adjusting plate, and a pre-networker. One end of the pre-networker is hinged to the base via at least two hinges. One end of the adjusting plate is connected to the bottom of the other end of the pre-networker, and the other end of the adjusting plate is connected to the base. The adjusting plate includes a first adjusting plate unit, a second adjusting plate unit, and a locking rod. One end of the first adjusting plate unit is provided with a first adjusting elongated hole, and the end of the second adjusting plate unit facing the first adjusting elongated hole is provided with a second adjusting elongated hole. The locking rod passes through the first adjusting elongated hole and the second adjusting elongated hole in sequence. Compared with the prior art, this utility model can facilitate the angle adjustment of the pre-networker, reduce yarn friction, and thus allow the yarn to pass smoothly through the pre-networker.

[0004] The aforementioned comparative documents still require relatively cumbersome steps in adjusting the angle of the pre-networker. In order to further optimize the adjustment process of the pre-networker position and improve the smoothness of the yarn passing through the pre-networker, an adjustable pre-networker for yarn machines is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an adjustable pre-networker for spinning machines, which allows for more convenient and stable adjustment of the pre-networker's tilt angle. Combined with a pneumatic control mechanism, this enables the filament bundle to pass through the pre-networker more smoothly.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable pre-network device for a spinning machine, comprising a base and a pre-network device mounted on the base, an adjustment mechanism being provided between the base and the pre-network device, the adjustment mechanism including a worm gear fixedly connected to the rotating shaft end of the pre-network device, a worm meshing with the worm gear being mounted on the upper surface of the base, a servo motor being fixedly connected to the upper surface of the base, the output shaft end of the servo motor being fixedly connected to the rotating shaft end of the worm, and a wire guiding mechanism and a pneumatic mechanism being installed inside the pre-network device, the pneumatic mechanism including a variable frequency blower fixedly connected to the bottom surface of the pre-network device, with the output end of the variable frequency blower facing upwards.

[0007] Through the above solution, an adjustable pre-networker for a spinning machine can adjust the tilt angle of the pre-networker by starting a servo motor, which drives the worm gear to rotate. This ensures that the pre-networker and the conveyor are aligned on the same straight line, reducing yarn friction. Furthermore, the combination of the worm gear and worm gear provides deceleration and self-locking effects, guaranteeing the stability of the pre-networker after adjustment and optimizing the process of adjusting its position. By starting a variable frequency blower, airflow can be generated upwards, using the airflow to create buoyancy and support the yarn through the lead-in mechanism, reducing direct contact between the yarn and the surface of the pre-networker and allowing the yarn to pass through the lead-in mechanism more smoothly, thus optimizing the device's performance.

[0008] Furthermore, the lead wire mechanism includes magnetic grooves formed on both sides of the upper surface of the pre-networker, and each magnetic groove has a plurality of magnetic blocks magnetically attached to its inner wall.

[0009] The above solution ensures the stability of the magnetic block and allows for adjustment of its position within the magnetic slot.

[0010] Furthermore, a lead wire is fixedly connected to the top of each magnetic block.

[0011] The above method can guide the filament bundle.

[0012] Furthermore, the pre-networker has several connecting rods inside, and the magnetic blocks on both sides are fixedly connected by two connecting rods.

[0013] The above method allows for the fixed connection of corresponding magnetic blocks on both sides, with the wire bundle passing through the lead wire.

[0014] Furthermore, a handle is fixedly connected to the outer surface of each magnetic block, and an anti-slip layer is coated on the outer surface of each handle.

[0015] The above solution allows for easy movement of the magnetic block and convenient adjustment of the wire guide's position, thus meeting the needs of wire bundle guidance in various situations.

[0016] Furthermore, a guide plate is installed above the variable frequency blower, and several connecting rods are located above the guide plate.

[0017] The above solution enables the airflow generated by the variable frequency blower to be delivered upwards more evenly.

[0018] Furthermore, a groove is provided on one side of the pre-network device, and a controller is installed on the inner wall of the groove. The variable frequency blower is electrically connected to the controller.

[0019] The above solution allows for easy adjustment of the airflow generated by the variable frequency blower by setting up a controller. By embedding the groove inside the pre-networker, the pre-networker can be easily folded and stored inside the base, reducing the space occupied by the device when not in use.

[0020] Furthermore, four positioning seats are fixedly connected to the bottom surface of the base, and each positioning seat has a positioning bolt threaded onto its inner wall.

[0021] The above solution allows the device to be installed in a suitable location, thereby facilitating the alignment of the pre-networker and the tunnel, and reducing filament friction.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This adjustable pre-networker for a spinning machine allows for adjustment of the pre-networker's tilt angle by activating a servo motor that drives a worm gear. This ensures the pre-networker is aligned with the feed path, reducing yarn friction. The combination of the worm gear and worm gear provides deceleration and self-locking, guaranteeing the stability of the pre-networker after adjustment and optimizing the pre-networker's position adjustment process. Furthermore, activating a variable frequency blower generates upward airflow, which creates buoyancy to support the yarn passing through the lead-in mechanism, reducing direct contact between the yarn and the pre-networker surface and allowing for smoother yarn passage through the lead-in mechanism. This optimizes the device's performance. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of an adjustable pre-network device for a spinning machine includes a base 1 and a pre-network device 2 mounted on the base 1. An adjustment mechanism 3 is provided between the base 1 and the pre-network device 2. The adjustment mechanism 3 includes a worm gear 301 fixedly connected to the rotating shaft end of the pre-network device 2. A worm 302 meshing with the worm gear 301 is mounted on the upper surface of the base 1. A servo motor 303 is fixedly connected to the upper surface of the base 1. The output shaft end of the servo motor 303 is fixedly connected to the rotating shaft end of the worm 302. A wire guiding mechanism 4 and a pneumatic mechanism 5 are installed inside the pre-network device 2. The structure 5 includes a variable frequency blower 501 fixedly connected to the bottom surface of the pre-networker 2, with the output end of the variable frequency blower 501 facing upward. By setting the variable frequency blower 501, airflow can be generated, and the airflow generates buoyancy, which can support the filament bundle and reduce the direct contact between the filament bundle and the surface of the pre-networker 2. Four positioning seats 6 are fixedly connected to the bottom surface of the base 1. Each positioning seat 6 has a positioning bolt 7 threadedly connected to its inner wall. By setting the positioning seats 6 and positioning bolts 7, the device can be installed in a suitable position, thereby facilitating the pre-networker 2 to be aligned with the channel and reducing filament bundle friction.

[0032] It should be noted that the combination of worm gear 301 and worm 302 has the effects of deceleration and self-locking. The deceleration effect can prevent the pre-networker 2 from being adjusted too quickly, which would cause inconvenience in operation. The self-locking effect can ensure that the pre-networker 2 can maintain relative stability after being adjusted to the appropriate position. The variable frequency blower 501 is an existing device, so it will not be described in detail or limited in too much. However, when the variable frequency blower 501 is started, it can generate airflow upwards, and the size of the airflow can be adjusted.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The wire guiding mechanism 4 includes magnetic grooves 401 formed on both sides of the upper surface of the pre-networker 2. Each magnetic groove 401 has several magnetic blocks 402 magnetically attached to its inner wall. By setting the magnetic grooves 401 and the magnetic blocks 402 to cooperate with each other, the stability of the magnetic blocks 402 can be ensured, and the position of the magnetic blocks 402 can be adjusted inside the magnetic grooves 401. A wire guide 403 is fixedly connected to the top of each magnetic block 402. The wire guide 403 guides the wire bundle. The pre-networker 2 has internal... Several connecting rods 404 are provided, and the magnetic blocks 402 on both sides are fixedly connected by two connecting rods 404. By setting the connecting rods 404, the corresponding magnetic blocks 402 on both sides can be fixedly connected. The wire bundle passes through the wire guide 403. Each magnetic block 402 has a handle 405 fixedly connected to its outer surface. The outer surface of each handle 405 is coated with an anti-slip layer. By setting the handles 405, the magnetic blocks 402 can be moved easily, and the position of the wire guide 403 can be adjusted to meet the wire bundle guidance work in various situations.

[0034] Please see Figure 1 , Figure 3 and Figure 4 A guide plate 502 is installed above the variable frequency blower 501, and several connecting rods 404 are located above the guide plate 502. By setting the guide plate 502, the airflow generated by the variable frequency blower 501 can be delivered upward more evenly. A groove 503 is opened on one side of the pre-network device 2. A controller 504 is installed on the inner wall of the groove 503. The variable frequency blower 501 is electrically connected to the controller 504. By setting the controller 504, the size of the airflow generated by the variable frequency blower 501 can be easily adjusted. By embedding the groove 503 inside the pre-network device 2, the pre-network device 2 can be easily folded and stored inside the base 1, which can reduce the space occupation rate of the device when not in use.

[0035] It should be noted that the wire bundle passes through the device via the lead wire mechanism 4, and both the guide plate 502 and the variable frequency blower 501 are located below the wire bundle. In this way, when the variable frequency blower 501 is started, the generated airflow can be used to support the wire bundle. Before use, the size of the airflow generated by the variable frequency blower 501 should be adjusted according to the condition of the wire bundle.

[0036] In this embodiment, an adjustable pre-networker for a spinning machine adjusts the tilt angle of the pre-networker 2 by activating a servo motor 303 to drive a worm gear 302, which in turn rotates a worm wheel 301. This adjustment ensures that the pre-networker 2 is aligned with the conveyor, thereby reducing friction in the yarn bundle. The worm wheel 301 and worm gear 302 are designed with deceleration and self-locking functions to ensure the pre-networker 2 remains stable after adjustment. Furthermore, by activating a variable frequency blower 501, airflow is generated above the pre-networker 2. This airflow creates buoyancy, supporting the yarn bundle passing through the lead-in mechanism 4, reducing direct contact between the yarn bundle and the surface of the pre-networker 2, allowing the yarn bundle to pass through the lead-in mechanism 4 more smoothly, thus optimizing the operation process and performance.

[0037] It should be noted that since the magnetic block 402 and the magnetic groove 401 are attracted by magnetic force, the airflow generated by the variable frequency blower 501 will not change the position of the magnetic block 402.

[0038] The working principle of the above embodiment is as follows: During use, the tilt angle of the pre-networker 2 can be adjusted by starting the servo motor 303. When the servo motor 303 starts, it drives the worm gear 302 to rotate. The rotation of the worm gear 302 can drive the worm wheel 301 to rotate the pre-networker 2, thereby achieving the effect of adjusting the tilt angle of the pre-networker 2. In this way, the pre-networker 2 can be adjusted to a position on the same straight line as the tunnel according to the site conditions, reducing the friction of the wire bundle. If it is necessary to adjust the position of the two corresponding wire guides 403, it can be achieved by moving the handle 405. Then, the wire bundle passes through the two corresponding wire guides 403. Next, the variable frequency blower 501 is started. When the variable frequency blower 501 starts, it generates an upward airflow. The airflow is evenly transported upward through the guide plate 502. The buoyancy generated by the airflow supports the wire bundle passing through the wire guide 403, reducing the direct contact between the wire bundle and the surface of the pre-networker 2.
