Description

Technical Field

[0001] This utility model relates to the field of glass fiber filament production technology, specifically to the slide shuttle of a glass fiber drawing machine. Background Technology

[0002] Glass fiber is an inorganic non-metallic material made from six kinds of minerals, including pyrophyllite and quartz sand, through high-temperature melting and drawing processes. It has the characteristics of good insulation, high temperature resistance (long-term resistance to 600℃), corrosion resistance and high mechanical strength. Glass fiber filaments are continuous fiber bundles formed by drawing molten glass from a platinum-rhodium alloy spinneret at high temperature. Each bundle consists of hundreds to thousands of monofilaments.

[0003] Currently, in the production of glass fiber precursor, the migration of sizing agent after drying leads to poor fiber penetration during deep processing, directly affecting product performance. To reduce moisture content, the production process needs to be optimized. However, in existing low-moisture processes, the contact between the yarn and the polyurethane board and copper rod easily produces yarn shavings, fuzz, and burrs, resulting in an increased product degradation rate and a significant increase in production costs. Therefore, a sliding shuttle for glass fiber drawing machines is proposed. By opening a yarn-reversing gap at one end of the layer plate, and having an arc-shaped contact surface on the inside of the yarn-reversing gap, the arc-shaped contact surface reduces yarn friction, ensures yarn laying stability, and avoids yarn breakage or deviation caused by uneven tension. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a sliding shuttle for a glass fiber drawing machine. By opening a yarn-reversing gap at one end of the layer plate, and having an arc-shaped contact surface on the inner side of the yarn-reversing gap, the arc-shaped contact surface reduces yarn friction, ensures yarn laying stability, and avoids yarn breakage or deviation caused by uneven tension.

[0005] The technical solution adopted by this utility model to solve its technical problem is a glass fiber drawing machine shuttle, including a slider and a yarn guide plate, characterized in that: a layer plate is provided on one side of the slider, the yarn guide plate is provided at the bottom of the layer plate, and a layer plate is provided at the front end of the yarn guide plate;

[0006] A yarn-reversing frame is provided on the top of the layer plate, and a yarn-reversing slit is opened at one end of the layer plate. The top of the yarn-reversing slit passes through the yarn-reversing frame, and the bottom of the yarn-reversing slit passes through the yarn guide plate. Both the yarn guide plate and the yarn-reversing frame are made of PEEK material.

[0007] By adopting the above technical solution, the yarn-reversing slit opened at one end of the layer plate facilitates the movement of the yarn, and the yarn guide plate and yarn-reversing frame are used to limit the yarn.

[0008] Specifically, the slider, the layer plate, and the yarn guide plate are integrally formed, and the top and bottom of the slider are provided with grooves that match the guide rail of the yarn drawing machine's yarn box.

[0009] Specifically, the slider has reinforcing ribs at both ends on the top side.

[0010] Specifically, a sliding fork mounting hole is provided on the side of the slider away from the reinforcing rib, and a sliding fork is sleeved on one side of the slider through the sliding fork mounting hole.

[0011] Specifically, an outwardly convex arc-shaped contact surface is provided on the inner side of the yarn guide gap, and the radius of the arc-shaped contact surface and the height of the yarn guide plate are both 13mm.

[0012] Specifically, the end of the yarn guide plate away from the layer plate is provided with an inclined surface.

[0013] The beneficial effects of this utility model are:

[0014] The glass fiber drawing machine shuttle of this utility model has yarn moving within the yarn rewinding gap. An arc-shaped contact surface is provided on the inner side of the yarn rewinding gap. The arc-shaped contact surface can reduce yarn friction, ensure yarn laying stability, and avoid yarn breakage or deviation caused by uneven tension. The yarn guide plate made of PEEK material has super wear resistance, self-lubrication and high temperature resistance, which makes the yarn move more smoothly in the yarn rewinding gap and is not easy to wear. The arc-shaped contact surface ensures uniform yarn laying tension and stable yarn running trajectory. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] By creating a yarn-reversing slit at one end of the shelf, with the inner side of the slit having an arc-shaped contact surface, yarn friction is reduced, ensuring yarn laying stability and preventing breakage or shifting of the yarn due to uneven tension. Figure 1-3As shown, the glass fiber drawing machine shuttle of this utility model includes a slider 31 and a yarn guide plate 12, characterized in that: a layer plate 11 is provided on one side of the slider 31, the yarn guide plate 12 is provided at the bottom of the layer plate 11, and the front end of the yarn guide plate 12 is provided with the layer plate 11.

[0022] The top of the layer 11 is provided with a yarn-turning frame 14, and a yarn-turning gap 111 is opened at one end of the layer 11. The top end of the yarn-turning gap 111 passes through the yarn-turning frame 14, and the bottom end of the yarn-turning gap 111 passes through the yarn guide plate 12. Both the yarn guide plate 12 and the yarn-turning frame 14 are made of PEEK material.

[0023] In use, the yarn-reversing slit 111 opened at one end of the shelf 11 facilitates the movement of the yarn, and the yarn guide plate 12 and the yarn-reversing frame 14 are used to limit the yarn.

[0024] For example, such as Figure 1 As shown, the present invention also includes the slider 31, the layer plate 11 and the yarn guide plate 12 integrally formed, and the top and bottom of the slider 31 are provided with grooves 312 that match the guide rail of the yarn drawing machine.

[0025] In use, the groove 312 facilitates the connection between the slider 31 and the guide rail on the wire drawing machine's wiring box.

[0026] For example, such as Figure 1 As shown, the present invention also includes reinforcing ribs 32 at both ends of the top side of the slider 31.

[0027] In use, the reinforcing rib 32 is provided to improve the connection strength between the slider 31 and the shelf 11.

[0028] For example, such as Figure 1 As shown, the present invention also includes a sliding fork mounting hole 41 through which the slider 31 is provided on the side away from the reinforcing rib 32, and a sliding fork 51 is sleeved on one side of the slider 31 through the sliding fork mounting hole 41.

[0029] When in use, the opening of the sliding fork mounting hole 41 facilitates the mounting of the sliding fork 51 on the slider 31.

[0030] For example, such as Figure 2 As shown, the present invention also includes an outwardly convex arc-shaped contact surface 110 provided on the inner side of the yarn guide 111, wherein the radius of the arc-shaped contact surface 110 and the height of the yarn guide plate 12 are both 13mm.

[0031] When in use, the radius of the arc-shaped contact surface 110 is 13mm, which ensures that the yarn comes out perfectly from the bottom of the shuttle and winds onto the drawing machine head during the process of the yarn cake outer diameter increasing and the machine arm moving backward.

[0032] For example, such as Figure 1 As shown, the present invention also includes an inclined surface 13 at the end of the yarn guide plate 12 away from the layer plate 11.

[0033] When in use, the inclined surface 13 allows the slider 31 to get closer to the yarn ball.

[0034] In use, the slider 31 can be installed on the guide rail of the wire drawing machine's cable box through the slide groove 312. The opening of the slide fork mounting hole 41 facilitates the installation of the slide fork 51. The slide fork 51 is driven by the camshaft to move along the guide rail of the cable box.

[0035] The inclined surface 13, relative to the yarn guide plate of the transmission, allows the slider 31 to get closer to the yarn ball without contacting it.

[0036] The yarn moves within the yarn-winding gap 111. An arc-shaped contact surface 110 is provided on the inner side of the yarn-winding gap 111. The arc-shaped contact surface 110 can reduce yarn friction, ensure yarn laying stability, and prevent yarn breakage or deviation caused by uneven tension.

[0037] The reinforcing rib 32 is used to improve the connection strength between the slider 31 and the layer plate 11. The yarn rewinding frame 14 and the yarn guide plate 12 are used to limit the yarn machine and prevent it from falling out of the yarn rewinding gap 111. The yarn guide plate 12, made of PEEK material, has super wear resistance, self-lubrication and high temperature resistance, so that the yarn moves more smoothly in the yarn rewinding gap 110 and is not easily worn.
