Description

Technical Field

[0001] This utility model belongs to the field of glass product manufacturing technology, specifically relating to a high-temperature and corrosion-resistant glass dropper. Background Technology

[0002] In the glass manufacturing process, the glass dropper is a key component in the forming process. It comes into direct contact with the high-temperature glass droplet and has a significant impact on forming quality and production efficiency. Traditional dropper heads mostly adopt an integrated fixed connection structure. Although the dropper itself has a certain degree of temperature resistance, it is still prone to cracking and wear under long-term high-temperature impact. Each time the dropper is replaced, it will cause a significant loss in output.

[0003] Patent CN114933406B discloses a feeding machine for eliminating scissor marks on glass droplets, including a frame, a punch up-and-down movement mechanism, a punch rotation mechanism, a punch, and a material tray. The punch up-and-down movement mechanism is connected to the frame; the punch rotation mechanism's power output end is connected to the punch, and the punch rotation mechanism is connected to the punch up-and-down movement mechanism, enabling it to move up and down, thereby driving the punch up and down; the material tray is located below the punch. The punch up-and-down movement mechanism drives the punch rotation mechanism, thus completing the formation of glass droplets; the punch achieves its rotation function through the punch rotation mechanism; the spiral blade, through continuous counterclockwise rotation and the upward movement of the punch, naturally draws the scissor marks from the glass droplets into the high-temperature zone of the material tray, where the scissor marks melt away.

[0004] Patent CN111908783B discloses a flow channel structure for easy replacement of a wire drawing baffle, including a working passage, a flow channel brick, a baffle brick, a wire drawing baffle, and a punch mechanism. The flow channel brick is disposed at the bottom of the working passage, the baffle brick is disposed at the bottom of the flow channel brick, and the wire drawing baffle is installed at the bottom of the baffle brick. The flow channel brick has flow holes. The punch mechanism includes a flow-blocking punch and a lifting mechanism for raising the flow-blocking punch. The flow-blocking punch is disposed at the top of the working passage and is used to block the flow holes. This patent controls the flow-blocking punch to block the flow holes in the flow channel brick, thus blocking the flow of molten glass in the working passage. During the replacement of the wire drawing baffle, there is no need to perform cooling and heating operations on the baffle brick, preventing crystallization and thus preventing clogging of the wire drawing baffle, thereby improving production efficiency.

[0005] While the aforementioned literature improves product quality and production efficiency through the design of punches and the overall equipment, the punches are still limited by the use of traditional materials and connection structures, which fails to further extend the overall service life of the punches. This results in a high frequency of punch replacements, which is not conducive to low-cost, high-efficiency long-term production.

[0006] Therefore, how to design a glass dropper that is highly durable, has a stable connection, and is flexible in disassembly has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] To address the shortcomings of the existing technology, this utility model provides a high-temperature and corrosion-resistant glass dropper. The glass dropper uses a metal dropper head with good temperature resistance and a connection structure to stably and detachably connect the metal dropper head to the dropper body. This solves the technical problems of low maintenance efficiency, poor durability at high temperatures, insufficient connection stability, and poor adaptability of the dropper.

[0008] Specifically, this utility model provides a high-temperature and corrosion-resistant glass dropper, including a dropper body, a dropper head, and a connecting structure;

[0009] The punch body and punch head are detachably fixed via a connecting structure;

[0010] The temperature resistance of the punch head is higher than that of the punch body.

[0011] This invention provides a stable connection and flexible disassembly structure through a reasonable connection structure design between the punch head and the punch body. The punch head is made of a material with higher temperature resistance and is not easily eroded or corroded when in direct contact with high-temperature molten glass. This can improve the overall durability of the punch and effectively control production costs, while significantly shortening maintenance time, reducing replacement frequency, and reducing production losses caused by production interruptions.

[0012] Preferably, the punch head is a metal punch head, selected from molybdenum metal punch heads or molybdenum alloy punch heads. Preferably, the punch body is a quartz ceramic punch body.

[0013] Traditional quartz ceramic punches have a high-temperature resistance of around 1300℃, but their service life is only about 15 days under the constant corrosion and erosion of high-temperature glass materials. By replacing the traditional quartz ceramic punch head with molybdenum metal or molybdenum alloy material, the temperature resistance is increased to around 1600℃, and the service life is increased by more than 10 times. This significantly enhances the temperature resistance and durability of glass material punches, effectively improving the output and quality of glass products. Furthermore, the punch body can still achieve significantly improved temperature and corrosion resistance using traditional quartz ceramic materials. This novel glass material punch structure and composition can be obtained by processing and adjusting existing punches or replacing disassembled punches and adding a metal punch head, thus improving overall durability and utilizing existing punches, saving costs. In addition, other high-temperature and corrosion-resistant materials can also be used for the punch head while meeting the requirements for high temperature and corrosion resistance.

[0014] Preferably, the glass dropper bar satisfies at least one of the following conditions:

[0015] (1) The outer diameters of the punch body and the punch head are the same;

[0016] (2) The punch body and the punch head are fixed coaxially;

[0017] (3) The length L1 of the punch body and the length L2 of the punch head satisfy: L1>3×L2.

[0018] Preferably, the punch body and punch head are coaxially fixed and have the same outer diameter. The actual outer diameter range is selected according to the overall equipment and production capacity requirements, for example, it can be selected from 25mm to 75mm. This design ensures the overall uniformity and stability of the glass drop punch during use, avoiding uneven glass drop formation caused by size differences.

[0019] By optimizing the structural ratio of the punch body and punch head, performance can be effectively improved, while facilitating quick replacement of the punch head and reducing maintenance time. The actual length range is selected based on the overall equipment and production capacity requirements. For example, the punch body length L1 can be 400-1000mm, and the punch head length L2 can be 100-300mm, ensuring both rigidity and operational stability, while reducing metal consumption and lowering costs while maintaining temperature and corrosion resistance.

[0020] The connection structure of this utility model has multiple design methods, with plug-in limiting fit and threaded fit being the preferred detachable fixing methods.

[0021] Preferably, the connecting structure includes a first connecting part, a second connecting part, and a rotation limiting member. The first connecting part is located at one end of the punch body, and the second connecting part is located at one end of the punch head. The connecting structure includes a first state and a second state. In the first state, the first connecting part and the second connecting part can slide along the axial direction of the glass drop punch. In the second state, the first connecting part and the second connecting part are limited along the axial and radial directions of the glass drop punch. The rotation limiting member limits the first connecting part and the second connecting part along the circumferential direction of the glass drop punch.

[0022] Preferably, the first connecting part includes a connecting post fixed coaxially with the punch body and a connecting block fixed with the connecting post, and the second connecting part includes a connecting ring fixed coaxially with the punch head and a connecting plate fixed with the connecting ring, and the connecting plate is provided with a disassembly and assembly channel for the first connecting part to pass through.

[0023] In the first state, the first connecting part can move circumferentially along the disassembly and assembly channel. In the second state, the projection of the connecting block along the axial direction of the disassembly and assembly channel partially overlaps with the connecting plate.

[0024] Preferably, the shape of the connecting block matches the shape of the disassembly channel, and the connecting block has a non-circular symmetrical structure. By optimizing the shape and structure design of the connecting block and the disassembly channel, incorrect installation can be effectively prevented, circumferential limiting and stable connection can be achieved, and relative rotation of the punch head can be prevented during use, thereby ensuring the working accuracy of the glass dropper punch.

[0025] Preferably, the end of the punch head with the second connecting part is also provided with a first limiting groove, and the connecting block is provided with a second limiting groove. The depth of the first limiting groove is less than the length of the rotating limiting member, and the depth of the second limiting groove is not less than the length of the rotating limiting member.

[0026] While ensuring the above-mentioned plug-in locking and easy disassembly, the depths of the first and second limiting grooves can be determined according to the length of the selected rotation limiting member. For example, optionally, when the length of the rotation limiting member is 10-25mm, the depth of the first limiting groove is 5-15mm, and the depth of the second limiting groove is 10-30mm.

[0027] Preferably, in the second state, the first limiting groove and the second limiting groove are arranged opposite to each other; the axis of the first limiting groove does not coincide with the axis of the punch head, and / or, the axis of the second limiting groove does not coincide with the axis of the connecting column. By designing the limiting grooves to be arranged opposite to each other and the axes to be misaligned, more complex limiting and fixing functions can be achieved, ensuring that the punch head remains locked even under complex working conditions such as high temperature.

[0028] Through the sliding, rotating, and limiting locking design, the punch head achieves triple anti-loosening in the axial, radial, and circumferential directions at high temperatures, improving the stability and reliability of the connection between the punch head and the punch body.

[0029] Preferably, the outer diameter of the first connecting part and / or the outer diameter of the second connecting part are the same as the outer diameter of the punch body. This design facilitates the formation of a streamlined punch after mating, eliminates abrupt changes in surface structure, avoids punch wear caused by molten glass residue, and significantly improves the consistency of droplet forming.

[0030] In another preferred embodiment, the connection structure includes a first threaded portion and a second threaded portion with a threaded fit. The first threaded portion is located at one end of the punch body, and the second threaded portion is located at one end of the punch head. This threaded fit structure is simple in design and easy to manufacture and use. Specifically, the first threaded portion can be configured as an external thread at one end of the punch body, and the second threaded portion as an internal thread at one end of the punch head. By rotating and tightening the internally threaded punch head relative to the externally threaded punch body, the punch head can be fixed to the end of the punch body. Furthermore, the positions of the internal and external threads can be interchanged, i.e., the first threaded portion can be configured as an internal thread, and the second threaded portion as an external thread.

[0031] Preferably, the first threaded portion includes a first guide portion, and the second threaded portion includes a second guide portion, with the first guide portion and the second guide portion engaging. Specifically, when the first threaded portion is an external thread and the second threaded portion is an internal thread, the first guide portion is a guide cylinder located at the end of the first threaded portion away from the punch body, and the second guide portion is a guide groove communicating with the second threaded portion and located inside the punch head. Conversely, when the first threaded portion is an internal thread and the second threaded portion is an external thread, the first guide portion is a guide groove communicating with the first threaded portion and located inside the punch body, and the second guide portion is a guide cylinder located at the end of the second threaded portion away from the punch head. The guiding engagement of the guide cylinder and the guide groove allows for more precise insertion, rotation, and fixation of the first and second threaded portions.

[0032] The glass slurry dropper provided by this utility model has at least the following beneficial effects:

[0033] (1) Improved durability: The use of temperature and corrosion resistant metal punch heads, especially molybdenum metal punch heads or molybdenum alloy punch heads that can withstand temperatures up to 1600℃, significantly improves the temperature and corrosion resistance of glass drop punches, enhances the durability of glass drop punches, and reduces punch consumption and maintenance costs.

[0034] (2) Improved ease of maintenance: The design of the connection structure between the punch body and the punch head enables quick disassembly and stable installation of the punch head and the punch body, improving production efficiency and reducing output loss due to punch replacement. In particular, it allows for the addition of a metal punch head based on simple modifications to existing punches, thereby improving the overall temperature and corrosion resistance of the punch.

[0035] (3) Optimized connection stability: Through the connection structure with axial, radial and circumferential limiting, the connection between the punch head and the body is ensured under high temperature conditions, which improves the stability and accuracy of the glass drop forming process.

Detailed Implementation

[0047] To better understand the above technical solutions, a detailed description of the solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0048] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.

[0049] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0050] This invention provides a high-temperature and corrosion-resistant glass dropper, comprising a quartz ceramic dropper body 1, a molybdenum metal dropper head 2, and a connecting structure 3. The dropper body 1 and the dropper head 2 are detachably fixed via the connecting structure 3. The dropper body 1 and the dropper head 2 are coaxially fixed and have the same outer diameter, approximately 45mm, ensuring overall uniformity and stability during use. To optimize structural proportions and improve performance, in this embodiment, the length L of the dropper body 1 is approximately 600mm and the length L2 of the dropper head 2 is approximately 180mm, satisfying L1 > 3 × L2.

[0051] like Figure 1 As shown, in the first embodiment, the connecting structure 3 adopts a detachable fixing method with plug-in limiting cooperation.

[0052] like Figure 2 As shown, the connecting structure 3 includes a first connecting part 31, a second connecting part 32, and a rotation limiting member 33.

[0053] like Figure 3-4 As shown, the first connecting part 31 is provided at one end of the punch body 1, including a connecting post 311 fixed coaxially with the punch body 1, a connecting block 312 fixed with the connecting post 311, and a second limiting groove 314 on the connecting block 312. The axis of the second limiting groove 314 does not coincide with the axis of the connecting post 311.

[0054] like Figure 5-6 As shown, the second connecting part 32 is located at one end of the punch head 2, including a connecting ring 321 coaxially fixed to the punch head 2, a connecting plate 322 fixed to the connecting ring 321, and a first limiting groove 324. The connecting plate 322 has a disassembly and assembly channel 323 through which the first connecting part 31 passes. The connecting block 312 has a non-circular symmetrical structure that matches the shape of the disassembly and assembly channel 323. The axis of the first limiting groove 324 does not coincide with the axis of the punch head 2.

[0055] according to Figure 7 The dimensions of the rotating limiting member 33 shown are designed such that the depths of the first limiting groove 324 and the second limiting groove 314 are such that the depth of the first limiting groove 324 is less than the length of the rotating limiting member 33, and the depth of the second limiting groove 314 is not less than the length of the rotating limiting member 33. This allows the rotating limiting member 33 to be simultaneously inserted into the first limiting groove 324 and the second limiting groove 314 to achieve the rotation limiting function and stabilize the connection structure. It can also be independently housed in the second limiting groove 314 so that the rotation limiting can be released and the punch head 2 can be rotated and disassembled from the punch body 1.

[0056] The specific installation and disassembly process of the high-temperature and corrosion-resistant glass dropper of the first embodiment of this utility model is as follows:

[0057] During installation, the first connecting part 31 and the second connecting part 32 slide along the axial direction of the glass dropper, allowing the first connecting part 31 to pass through the disassembly channel 323. Then, they rotate relative to each other. When the first limiting groove 324 and the second limiting groove 314 are positioned opposite each other, the rotating limiting member 33 is simultaneously inserted into the first limiting groove 324 and the second limiting groove 314, circumferentially limiting the first connecting part 31 and the second connecting part 32. At this time, the projection of the connecting block 312 along the axial direction of the disassembly channel 323 partially overlaps with the connecting plate 322, and the connecting block 312 and the connecting plate 322 form an axial engagement, locking the dropper head 2 and the dropper body 1 along the axis.

[0058] Through the above steps, the punch head 2 and the punch body 1 are firmly connected, ensuring stability under complex working conditions.

[0059] When it is necessary to disassemble and replace the punch head 2, reverse the connection between the punch head 2 and the punch body 1 so that the rotation limit member 33 is fully accommodated in the second limit groove 314, thereby releasing the circumferential limit lock of the rotation limit member 33. Then, rotate the punch head 2 circumferentially relative to the punch body 1. When the connecting block 312 of the first connecting part 31 corresponds to the disassembly and assembly channel 323, slide the punch head 2 and the punch body 1 axially to separate them, thereby quickly disassembling the punch head 2.

[0060] like Figure 8 As shown, in the second embodiment, the connecting structure 3 adopts a detachable fixing method with threaded engagement.

[0061] The connecting structure 3 includes a first threaded portion 34 and a second threaded portion 35 with threaded engagement. The first threaded portion 34 is located at one end of the punch body 1, and the second threaded portion 35 is located at one end of the punch head 2. The first threaded portion 34 is an external thread at one end of the punch body 1, and the second threaded portion 35 is an internal thread at one end of the punch head 2. By rotating and tightening the internally threaded punch head 2 relative to the externally threaded punch body 1, the punch head 2 can be fixed to the end of the punch body 1. Furthermore, by rotating in the opposite direction, the punch head 2 can be easily removed from the punch body 1.

[0062] Similarly, such as Figure 9 As shown, in the third embodiment, the first threaded portion 34 further includes a first guide portion 341, and the second threaded portion 35 includes a second guide portion 351. The first guide portion 341 and the second guide portion 351 cooperate with each other. The first guide portion 341 is a guide cylinder located at the end of the first threaded portion 34 away from the punch body 1, and the second guide portion 351 is a guide groove communicating with the second threaded portion 35 and located inside the punch head 2. The circumferential cooperation of the guide cylinder and the guide groove allows for more precise insertion, rotation, and fixing of the first threaded portion 34 and the second threaded portion 35.

[0063] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
