Description

Technical Field

[0001] This utility model relates to the field of high-strength, high-modulus polyvinyl alcohol fiber production technology, specifically to a pneumatic fiber guide device for a cooling machine. Background Technology

[0002] In the production of high-strength, high-modulus polyvinyl alcohol (PVA) fibers, a cooling process is involved. The equipment currently used is called a cooling machine, and its purpose is to reduce the temperature of the fiber bundle from 160℃ to approximately 45℃. The cooling machine includes cooling rollers, cooling roller supports, rotary pressure joints, a transmission device, and a guide device. After cooling, the PVA fibers need to be wound and collected using the guide device. It is important to note that "roller" is a common term used in the chemical fiber and spinning industries for "roller," generally referring to any cylindrical rotating body used to support, transport, compress, or redirect fiber bundles.

[0003] The device includes a support, a rubber roller, a guide wire tray, a guide roller, a triangular support, a rubber roller support, and a counterweight. The counterweight and the rubber roller are fixed on the rubber roller support. The rubber roller support and the triangular support are axially rotatably connected. The guide roller is fixed on the triangular support. The triangular support is fixed on the frame. The rubber roller is located directly above the guide wire tray.

[0004] During operation, the rubber roller bracket needs to be lifted manually. After releasing it, the rubber roller is lowered back to its original position using the counterweight. Because the rubber roller and the counterweight have a certain weight, this operation has a large impact on the rubber roller and the connecting shafts and fixing bolts, resulting in severe wear on the parts. The gaps caused by the wear can also cause the entire device to be inaccurately positioned. At the same time, there is a risk that the counterweight bolts may loosen and fall, causing injury. This operation is also quite laborious. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a pneumatic wire guide device for a cooling machine.

[0006] The objective of this utility model can be achieved through the following technical solutions: A pneumatic wire guiding device for a cooling machine includes a frame, a guide roller, a wire guiding disc, a bearing seat, a rubber roller, and a lifting mechanism; the guide roller is fixed to the wire feeding side of the frame, the wire guiding disc is rotatably mounted on the frame via the bearing seat, and the rubber roller is located above the wire guiding disc and arranged parallel to the wire guiding disc; The lifting mechanism includes a support frame fixedly connected to the frame, a cylinder fixedly mounted on the support frame, the cylinder having a telescopic rod, a connector at one end of the telescopic rod, a retainer at one end of the connector, an mounting shaft on the retainer, and a rubber roller mounted on the mounting shaft.

[0007] The guide plate is used to pull and convey the filament bundle, the rubber roller is used to cooperate with the guide plate to clamp and stabilize the filament bundle, and the lifting mechanism is used to drive the rubber roller to move closer to or away from the guide plate to achieve clamping or releasing of the filament bundle.

[0008] As a further embodiment of this utility model: the support frame is provided with a through groove for the telescopic rod and the connector to move, and the connector passes through the through groove and moves up and down along the inner wall of the through groove.

[0009] As a further embodiment of this utility model: the connector includes a protective sleeve threaded onto the through groove and a connecting rod slidably connected within the protective sleeve, one end of the connecting rod being fixedly connected to the telescopic rod and the other end being fixedly connected to the protective frame.

[0010] As a further embodiment of this utility model: the retainer has a horizontal plate and two downwardly extending and parallel retaining plates. The mounting shaft is perpendicular to the movement path of the connecting rod and is fixedly connected between the two retaining plates. The two retaining plates are located on the front and rear sides of the rubber roller, respectively.

[0011] As a further embodiment of this utility model: the guide wire disc is made of metal rollers, and the rubber rollers are made of polyurethane-coated rollers.

[0012] As a further embodiment of this utility model: both sides of the guide roller are provided with outwardly protruding flanges.

[0013] As a further embodiment of this utility model: the guide wire disc is fixedly installed on the drive shaft by a key connection, and the drive shaft is rotatably installed on the frame through the bearing seat.

[0014] As a further embodiment of this invention: the drive shaft has a tapered section that facilitates the insertion of the guide wire disc.

[0015] As a further embodiment of this utility model: the support frame is provided with an air source treatment component and a reversing valve.

[0016] As a further embodiment of this invention: the gas source treatment assembly consists of a filter, a pressure reducing valve, and an oil mist lubricator connected in series.

[0017] The beneficial effects of this utility model are as follows: When this device is working, the filament bundle enters from the infeed side, is guided by the guide roller to the space between the guide plate and the rubber roller, and the lifting mechanism drives the telescopic rod to move up and down through the cylinder, thereby driving the mounting shaft and the rubber roller to move up and down through the connecting parts and the retainer, so as to clamp or release the filament bundle.

[0018] Compared to traditional manual control of the rubber roller and counterweight lifting, this equipment controls the raising and lowering of the rubber roller by controlling the extension and retraction of the cylinder, achieving truly labor-saving operation. Unlike traditional equipment where the counterweight falls instantly due to gravity, generating a huge impact on mechanical structures (such as connecting shafts and fixing bolts), the controllable movement speed of the cylinder greatly reduces the impact and vibration on the entire device, significantly lowering operating noise. Furthermore, this device completely eliminates the bulky counterweight, avoiding potential safety issues such as loose screws and accidental counterweight drops. Additionally, due to the significantly reduced impact force, mechanical wear on various components is significantly reduced, extending service life. The equipment can maintain high positioning accuracy for extended periods, reducing downtime and costs associated with maintenance and component replacement. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-3 An embodiment of the present invention provides a pneumatic wire guiding device for a cooling machine, comprising a frame 1, a guide roller 2, a wire guiding disc 3, a bearing seat 4, a rubber roller 5, and a lifting mechanism 6. The guide roller 2 is fixed to the wire feeding side of the frame 1, the wire guiding disc 3 is rotatably mounted on the frame 1 via the bearing seat 4, and the rubber roller 5 is located directly above the wire guiding disc 3 and arranged parallel to the wire guiding disc 3. The lifting mechanism 6 includes a support frame 61 fixedly connected to the upper side of the frame 1. The support frame is inverted L-shaped, and a cylinder 62 is fixedly mounted on the support frame 61. The cylinder 62 is mounted on the extended end of the upper part of the support, and the cylinder 62 has a telescopic rod 63. One end of the telescopic rod 63 is provided with a connector 64, and one end of the connector 64 is provided with a retainer 65. The retainer 65 is provided with a mounting shaft 66, and the rubber roller 5 is mounted on the mounting shaft 66.

[0024] Among them, the guide roller 3 is used to pull and convey the filament bundle, the guide roller 2 has a smooth surface and can rotate actively or passively to guide the direction of the filament bundle, the rubber roller 5 (also known as the pressure roller) is covered with rubber or polyurethane on the outside and uses elasticity to press the filament bundle to prevent slippage, the rubber roller 5 is used to cooperate with the guide roller 3 to clamp and stabilize the filament bundle, and the lifting mechanism 6 is used to drive the rubber roller 5 to move closer to or away from the guide roller 3 to achieve clamping or releasing of the filament bundle.

[0025] Specifically, when this device is working, the filament bundle enters from the infeed side and is guided by the guide roller 2 to the space between the guide plate 3 and the rubber roller 5. The lifting mechanism 6 drives the telescopic rod 63 to move up and down through the cylinder 62, thereby driving the mounting shaft 66 and the rubber roller 5 to move up and down through the connector 64 and the retainer 65, so as to clamp or release the filament bundle.

[0026] Furthermore, compared to the traditional manual control of the rubber roller 5 and the lifting of the counterweight, this equipment controls the lifting and lowering of the rubber roller 5 by controlling the extension and retraction of the cylinder 62, achieving truly labor-saving operation. Unlike traditional equipment where the counterweight falls instantly due to gravity, generating a huge impact on the mechanical structure (such as connecting shafts and fixing bolts), the controllable movement speed of the cylinder 62 greatly reduces the impact and vibration on the entire device, significantly lowering operating noise. In addition, this device completely eliminates the bulky counterweight, avoiding potential safety issues such as loose screws and accidental counterweight drops. Moreover, due to the significantly reduced impact force, mechanical wear on various components is significantly reduced, extending service life. The equipment can maintain high positioning accuracy for extended periods, reducing downtime and costs associated with maintenance and component replacement.

[0027] See Figure 1 and Figure 3 Optionally, the support frame 61 is provided with a through groove 611 for the telescopic rod 63 and the connector 64 to move. The connector 64 passes through the through groove 611 and moves up and down along the inner wall of the through groove 611.

[0028] In this embodiment, the telescopic rod 63 can drive the connector 64 to move synchronously, and the through groove 611 can limit the movement trajectory of the connector 64, prevent the connector 64 from swaying, and guide the retainer 65 and the rubber roller 5 to rise and fall smoothly. When the surface of the rubber roller 5 is affected by the filament bundle, the presence of the through groove 611 and the connecting rod 642 effectively prevents the telescopic rod 63 from swaying, thus extending the service life of the cylinder 62 and the telescopic rod 63.

[0029] See Figure 1 and Figure 3 Optionally, the connector 64 includes a protective sleeve 641 threaded to the inside of the through groove 611 and a connecting rod 642 slidably connected to the protective sleeve 641. One end of the connecting rod 642 is fixedly connected to the telescopic rod 63, and the other end is fixedly connected to the protective frame.

[0030] In this embodiment, the protective sleeve 641 can protect the connecting rod 642, effectively reduce the wear of the connecting rod 642, prevent dust from entering the inside of the through groove 611, and improve the durability and reliability of the connecting rod 642. The protective sleeve 641 can be made of wear-resistant composite material with low friction, such as polytetrafluoroethylene.

[0031] See Figure 1 Optionally, the retainer 65 has a horizontal plate 651 perpendicular to the movement path of the connecting rod 642, two downwardly extending and parallel to each other and perpendicular to the horizontal plate 651, and a mounting shaft 66 perpendicular to the movement path of the connecting rod 642 and fixedly connected between the two retaining plates 652. The two retaining plates 652 are located on the beginning and end sides of the rubber roller 5, respectively.

[0032] In this embodiment, the retainer 65 is configured as a gate-shaped structure to stably support the rubber roller 5, so that the tension of the filament bundle on the rubber roller 5 is automatically centered, avoiding axial movement, ensuring that it is parallel to the guide plate 3, improving clamping uniformity, and preventing the filament bundle from deviating or being damaged.

[0033] See 1 and Figure 2 Optionally, the guide wire disc 3 uses a metal roller, and the rubber roller 5 is an externally coated polyurethane roller.

[0034] In this embodiment, the metal rollers are wear-resistant, the metal guide roller 3 provides rigid support, and the polyurethane rubber roller 5 provides elastic clamping. Furthermore, the polyurethane rollers are non-slip and protect the wire bundle. The rigid design of the guide roller 3 and the elastic design of the rubber roller 5 effectively improve the transmission efficiency and wire bundle protection performance of this device.

[0035] See Figure 2 and Figure 4 Optionally, both sides of the guide roller 2 are provided with outwardly protruding flanges 21.

[0036] In this embodiment, the flanges 21 on both sides can limit the movement path of the filament bundle, allowing the filament bundle to pass through the middle of the guide roller 2 and preventing the filament bundle from falling off.

[0037] See Figure 1 and Figure 5 Optionally, the guide wire disc 3 is fixedly installed on the drive shaft 31 by a key connection, and the drive shaft 31 is rotatably installed on the frame 1 through the bearing seat 4.

[0038] In this embodiment, the key connection method can ensure reliable transmission and avoid slippage.

[0039] See Figure 5 Optionally, the drive shaft 31 has a tapered section 311 for easy insertion of the guide wire disc 3.

[0040] In this embodiment, the tapered segment 311 can automatically guide and initially align the guide wire disc 3 during installation, making the key connection assembly faster and more precise.

[0041] See Figure 1 Optionally, the support frame 61 is provided with an air source treatment component 621 and a reversing valve 622. The air source treatment component 621 is a triple unit arranged in series. The inlet of the triple unit is connected to the compressed air pipeline in the workshop, and the outlet is connected to the upper and lower chamber interfaces of the cylinder 62 via the reversing valve 622, so as to provide the cylinder 62 with clean, pressure-stabilized and lubricated compressed air.

[0042] In this embodiment, the reversing valve 622 can change the flow direction of compressed air. When the reversing valve 622 switches to different working positions, compressed air enters different chambers of the cylinder 62, thereby controlling the extension and retraction direction of the cylinder 62.

[0043] Referring to 1, optionally, the gas source treatment assembly 621 consists of a filter, a pressure reducing valve, and an oil mist lubricator connected in series.

[0044] In this embodiment, the air filter is used to filter impurities in the compressed air to prevent impurities from entering the cylinder 62 and damaging its internal structure; the pressure reducing valve can adjust the air pressure entering the cylinder 62, and set an appropriate pressure value according to actual production needs to control the degree of compression of the high-strength, high-modulus polyvinyl alcohol fiber by the rubber roller 5; the oil mist lubricator can lubricate the inside of the cylinder 62 to reduce friction between components.
