Description

Technical Field

[0001] This invention relates to the field of glass fiber production equipment technology, and in particular to an integrated tooling for glass fiber drawing. Background Technology

[0002] In the fiberglass yarn drawing process, routine installation, maintenance, and adjustment of tooling components such as the drawing spool, nozzles, silver sheets, and supports are required. Common operations include tightening or loosening screws, aligning silver sheets, cleaning crystals from nozzles, and unclogging nozzles. These operations typically require the use of various tools, such as open-end wrenches, Allen wrenches, hooks, and needles.

[0003] However, the glass drawing production environment is unique: the temperature of the spinneret and molten glass reaches 1200-1300℃, generating intense high-temperature radiation. Traditional tools are not specifically designed for this high-temperature environment in terms of size and structure, making operators prone to burns or punctures from tool tips (such as needles). Furthermore, the large variety and length of tools required make storage and management inconvenient. Randomly placed tools are prone to loss and abnormal wear, increasing production costs.

[0004] While existing technologies include combination tools with replaceable tool heads, the connection between the tool head and the connecting rod is prone to loosening or even detachment during repeated tightening operations due to vibration or changes in the direction of operating torque. This not only affects operational efficiency but also poses safety hazards. Furthermore, under prolonged high-temperature radiation operation, heat can be conducted along the metal tool shaft to the handle, making it difficult for operators to accurately judge whether the handle temperature has exceeded a safe range by touch, thus posing a risk of burns.

[0005] Therefore, there is an urgent need to develop an integrated tooling system that can adapt to the high-temperature environment of glass fiber drawing, is easy to store and manage, is safe to use, and has reliable connections. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an integrated tooling fixture for glass fiber drawing, so as to solve the technical problems of existing tools being of many types, long in size, inconvenient to store, easy to loosen the connection, and unable to intuitively monitor the temperature of the handle.

[0007] The integrated tooling for glass fiber drawing of the present invention includes:

[0008] The main connecting rod has a heat-insulating component at its handle section;

[0009] Multiple functional tool heads with different functions are detachably mounted on the connecting end of the main connecting rod;

[0010] The main connecting rod and the functional tool head are connected by a rotary locking mechanism. The rotary locking mechanism is configured such that when the functional tool head performs its predetermined function of turning, the operating torque applied to the main connecting rod is directed in the direction of locking the connection between the main connecting rod and the functional tool head.

[0011] The heat insulation component integrates a temperature warning module, which can directly generate a warning signal related to the temperature of the handheld section of the main connecting rod, which can be directly identified by the operator's senses.

[0012] Furthermore, the rotary locking mechanism is specifically configured such that: the main connecting rod has at least two connecting ends, wherein at least one connecting end is provided with an internal thread in a first direction of rotation, and at least the other connecting end is provided with an internal thread in a second direction of rotation with the opposite direction of rotation; the functional tool head is correspondingly divided into a first tool head group and a second tool head group, which are respectively provided with external threads that match the internal threads in the first and second directions of rotation; such that when using the first tool head group for tightening operations and / or using the second tool head group for loosening operations, the operating torque is directed in the direction of the locking thread connection.

[0013] Furthermore, the functional tool head includes at least one of the following: a silver sheet calibrator, an internal hex wrench, an open-end wrench, a leak-nozzle crystallization hook, and a leak-nozzle needle; and when the functional tool head is an internal hex wrench, its functional end is magnetic.

[0014] Furthermore, the functional end of the silver sheet corrector is a forked opening; the functional end of the leak nozzle crystallization hook is a curved hook; and the functional end of the leak nozzle piercing needle is a straight piercing needle.

[0015] Furthermore, the temperature warning module is a reversible thermochromic layer disposed on the heat insulation component. The reversible thermochromic layer provides a visual temperature warning signal by undergoing a reversible color change with temperature.

[0016] Furthermore, the reversible thermochromic layer is configured to begin changing color when the handle temperature reaches 50°C to 70°C.

[0017] Furthermore, the reversible thermochromic layer includes at least two indicator areas, each indicator area being formed of a reversible thermochromic material with a different color-changing temperature, so as to produce color changes at different temperature levels, thereby constituting a multi-level temperature visual warning.

[0018] Furthermore, the reversible thermochromic layer is made of inorganic reversible thermochromic material or microencapsulated reversible thermochromic material, and is combined with the heat insulation component by coating, patching or embedding.

[0019] Furthermore, the main connecting rod is a hollow tube with one end closed and the other end open, and its internal thread is provided on the inner wall of the open end; the external thread connecting section of the functional tool head is provided at one end, and the other end is the functional end.

[0020] Furthermore, the heat insulation component is a silicone sleeve with a threaded anti-slip structure on its outer surface.

[0021] The beneficial effects of this invention are as follows: The integrated tooling for glass fiber drawing of this invention, through modular integrated design, connects the main connecting rod with multiple functional tool heads using a detachable rotary locking mechanism, and is equipped with internally threaded connecting ends with opposite rotation directions and corresponding tool head groups, so that the torque during tightening or loosening operations always points in the locking direction, fundamentally eliminating the possibility of tool heads accidentally falling off during operation. At the same time, it significantly reduces the size of a single piece, making it easier to store and manage and reducing loss and damage. The reversible thermochromic temperature warning module integrated on the heat insulation component can generate intuitive visual warning signals according to the temperature change of the handle, allowing operators to judge whether the handle temperature is within the safe range in real time without the aid of instruments, effectively preventing burn accidents. It also achieves gradient warning through multi-level color-changing areas, further improving the safety of high-temperature operations. It has the advantages of compact structure, safe use, economic practicality and low maintenance cost. Attached Figure Description

Figure 2 This is a schematic diagram of the structure of the silver sheet corrector of the present invention. Figure 3 This is a schematic diagram of the internal hex wrench of the present invention. Figure 4 This is a schematic diagram of the open-end wrench of the present invention. Figure 5 This is a schematic diagram of the structure of the crystallization hook needle for the leak nozzle of the present invention. Figure 6 The figure shows a schematic diagram of the nozzle-punching needle of the present invention. This embodiment of the integrated tooling for glass fiber drawing is specifically designed for high-temperature operations such as nozzle maintenance, silver sheet correction, and screw tightening in glass fiber drawing production. It includes: a main connecting rod 1, with a heat-insulating component at its handle section. This heat-insulating component blocks heat conducted along the metal rod from the functional end, reducing the surface temperature of the handle and preventing burns to the operator's hands; multiple functional tool heads with different functions are detachably installed at the connecting end of the main connecting rod 1. Operators can quickly change the corresponding tool head according to specific operational needs, eliminating the need to carry multiple independent long-handled tools, significantly reducing the number of tools and facilitating storage and standardized management in the drawing workshop; the main connecting rod 1 and the functional tool heads are connected by a rotary locking mechanism. The mechanism is configured such that when the functional tool head performs its predetermined function of tightening, the operating torque applied to the main connecting rod 1 is directed in the direction of locking the connection between the main connecting rod 1 and the functional tool head. This makes the connection tighter with repeated tightening operations, mechanically eliminating the risk of the tool head accidentally loosening and falling off, and ensuring the continuity and safety of operation in high-temperature environments. The heat insulation component integrates a temperature warning module, which can directly generate a warning signal related to the temperature of the handheld section of the main connecting rod 1, which can be directly identified by the operator's senses. The operator can intuitively judge whether the handle temperature has exceeded the safe range without interrupting the operation or using additional temperature measuring instruments, and take timely measures such as pausing the operation or strengthening protection. This effectively makes up for the shortcomings of traditional tools that rely on experience judgment and cannot monitor the handle temperature in real time.

[0031] In this embodiment, the rotary locking mechanism is specifically configured such that: the main connecting rod 1 has at least two connecting ends, at least one of which has an internal thread with a first direction of rotation, i.e., a clockwise thread 102, and at least the other connecting end has an internal thread with a second direction of rotation, i.e., a counter-clockwise thread 103; the functional tool head is correspondingly divided into a first tool head group and a second tool head group, each having an external thread that matches the internal threads of the first and second directions of rotation, respectively; so that when using the first tool head group for tightening operations and / or using the second tool head group for loosening operations, the operating torque is directed in the direction of the locking thread connection. This design allows the operator to use the tool with the clockwise thread 102 combination when tightening screws and the tool with the counter-clockwise thread 103 combination when loosening screws. In both operations, the turning direction tends to tighten the connection between the tool head and the connecting rod, ensuring a firm and reliable connection. This avoids the problem of traditional single-direction thread tools gradually loosening at the connection point during reverse operations. Furthermore, the clear distinction between clockwise and counter-clockwise threads facilitates quick identification and selection of the correct tool combination by the operator.

[0032] In this embodiment, the functional tool head includes at least one of the following: a silver sheet calibrator 2, an internal hex wrench 3, an open-end wrench 4, a leak nozzle crystallization hook 5, and a leak nozzle shovel 6. It covers all the tool types required for the main operations in wire drawing production, such as leak plate maintenance, screw tightening, crystallization cleaning, and leak nozzle unblocking, achieving the integrated goal of "one tool for multiple uses". When the functional tool head is an internal hex wrench 3, its functional end is magnetic, which can attract the screw by magnetic force when loosening the internal hex screw, preventing the screw from falling into the high-temperature leak plate area or the ground and causing loss and safety hazards. It is especially suitable for working around the leak plate in confined spaces, high temperatures, and where it is difficult to pick up the screw.

[0033] In this embodiment, the functional end of the silver sheet corrector 2 is a forked end with a preferred fork spacing of 1mm, which can accurately engage the silver sheet in the stencil for correction and adjustment, ensuring that the silver sheet spacing meets the requirements of the wire drawing process. The functional end of the stencil crystallization hook 5 is a curved hook, which is convenient to extend into the stencil area to remove precipitated glass crystals and clean the crystallization blockage around the stencil. The functional end of the stencil lance 6 is a straight lance, used to unclog the blockage inside the stencil lance and restore the normal flow function of the stencil. Each functional end is specially designed according to the actual operational needs of the wire drawing site, making it convenient to operate and highly targeted.

[0034] In this embodiment, the temperature warning module is a reversible thermochromic layer disposed on the heat insulation component. The reversible thermochromic layer provides a visual temperature warning signal by undergoing a reversible color change with temperature. During the glass fiber drawing process, the temperature of the baffle and molten glass reaches 700-900℃. Although the main connecting rod 1 is 50cm long and is covered with a silicone heat insulation sleeve, heat radiation will still gradually be conducted along the metal rod to the handle during long-term continuous operation, causing the handle temperature to rise slowly. The reversible thermochromic layer changes color when the temperature rises and automatically recovers the color when the temperature drops. It can be reused repeatedly without batteries or external power supply, making it economical, practical, simple, reliable, and seamlessly integrated with the tool body.

[0035] In this embodiment, the reversible thermochromic layer is configured to begin changing color when the handle temperature reaches 50°C to 70°C. This temperature threshold is set higher than the human comfort temperature but lower than the common burn temperature, providing an early warning before the operator feels significant discomfort or suffers a burn, allowing sufficient reaction time. Once the operator observes the color change, they can determine that the handle temperature has risen to the warning range and should immediately stop operation or take measures such as replacing tools or strengthening heat insulation, thereby effectively preventing burns caused by overheating of the handle.

[0036] In this embodiment, to further improve the precision of temperature warning, the reversible thermochromic layer includes at least two indicator areas. Each indicator area is formed of a reversible thermochromic material with a different color-changing temperature, so that it produces color changes at different temperature levels, forming a multi-level temperature visual warning. For example, three indicator areas can be set on the surface of the silicone sleeve 101: the first area has a color-changing temperature of 45-50°C, and the color changes from its original color to a lighter color, indicating that the handle is starting to heat up and the operator should pay attention; the second area has a color-changing temperature of 60-65°C, and the color changes from its original color to a warning color such as orange, indicating that the handle temperature is high and vigilance is required; the third area has a color-changing temperature of 75-80°C, and the color changes from its original color to a high-risk color such as red, indicating that the handle temperature is too high and operation should be stopped immediately. Through multi-level color changes, the operator can more accurately grasp the thermal state of the handle and take corresponding measures in a timely manner, further reducing the risk of high-temperature operation.

[0037] In this embodiment, the reversible thermochromic layer is made of inorganic reversible thermochromic materials or microencapsulated reversible thermochromic materials. Inorganic reversible thermochromic materials, such as mercuric iodide silver-based materials, change color upon heating due to a change in crystal form, and the crystal form and color are restored upon cooling. They have the characteristics of good heat resistance, long reversible lifespan (up to thousands of times), and are very suitable for the harsh environment of high-temperature radiation and frequent operation in wire drawing workshops. Microencapsulated reversible thermochromic materials improve the stability and weather resistance of the thermochromic agent through microencapsulation technology, and are also suitable for repeated use. The reversible thermochromic layer is combined with the heat insulation component by coating, patching, or embedding: the coating method involves mixing the color-changing material with a high-temperature resistant base material, coating it onto the surface of the silicone sleeve 101, and curing it to form a coating, which is simple and low-cost; the patching method involves encapsulating the color-changing material in a high-temperature resistant film to make a temperature-indicating patch, which is then pasted onto the surface of the silicone sleeve 101 for easy replacement after wear; the embedding method involves embedding the color-changing material into a predetermined position within the sleeve wall during the molding of the silicone sleeve 101 to form an integrated structure with better durability.

[0038] In this embodiment, the main connecting rod 1 is a hollow tube with one end sealed and the other open. It is preferably made of stainless steel, possessing high temperature resistance, corrosion resistance, and high strength. Its internal thread is located on the inner wall of the open end, with a thread length of 30mm, ensuring reliable connection and ease of manufacturing. The external threaded connection section of the functional tool head is located at one end, also 30mm long, matching the threaded section of the main connecting rod 1. The other end is the functional end, used to perform specific wire drawing maintenance operations. Each functional tool head is approximately 330mm long. Combined with the main connecting rod 1, the overall length is moderate, ensuring a safe distance from the high-temperature baffle during operation without compromising operational flexibility or storage convenience due to excessive length. After disassembly, the dimensions of each component are only about 63% of existing independent long-handled tools, making them easier to store in a tool storage box and facilitating standardized management in the wire drawing workshop.

[0039] In this embodiment, the heat insulation component is a silicone sleeve 101. The silicone material has good heat insulation and high temperature resistance, which can effectively block heat from being transferred to the handle. Its outer surface has a threaded anti-slip structure, which increases the friction between the palm and the handle. Even when the operator's hands are sweaty or wearing gloves, the tool can be held firmly, preventing it from slipping during operation and further improving the safety of use.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
