Description

Technical Field

[0001] This utility model relates to the field of glass tube drawing technology, specifically to a glass tube wall thickness adjustment device for glass furnaces. Background Technology

[0002] With the development of the glass tube manufacturing industry, the technical requirements for its manufacturing machinery are gradually increasing. In glass tube drawing, product wall thickness and quality are mainly controlled by adjusting the forming gap. However, traditional adjustment structures are complex, the operating environment is poor, manual adjustment easily leads to uneven gaps, and it is impossible to observe the forming gap adjustment in a timely manner, making it impossible to respond promptly to parameter changes. Untimely adjustments can cause wall thickness to exceed standards, affecting glass tube quality, reducing yield, increasing scrap rate, and also impacting subsequent bottle-making processes, disrupting the stability of the production chain and product quality, and restricting enterprise efficiency and competitiveness. This is a technical bottleneck that the industry urgently needs to overcome.

[0003] Moreover, from the perspective of production efficiency, traditional production methods often require a long time to adjust equipment parameters to adapt to the production of different specifications of Velofara glass tubes, and the frequent equipment failures and rework of defective products during the production process further reduce production efficiency. Utility Model Content

[0004] This invention proposes a glass tube wall thickness adjustment device for glass furnaces, which solves the problem in related technologies that the glass tube processing equipment cannot monitor the glass tube wall thickness adjustment in real time during the glass tube processing process.

[0005] The technical solution of this utility model is as follows:

[0006] A glass tube wall thickness adjustment device for a glass furnace includes:

[0007] The main body has a receiving cavity with an outlet, the receiving cavity being used to contain molten glass;

[0008] A conical platform is raised and lowered on the main body, and the conical platform forms a forming gap with the outlet. The size of the forming gap can be adjusted by raising and lowering the conical platform.

[0009] A rotating component is rotatably mounted on the main body;

[0010] A pointer is positioned on the rotating component.

[0011] Optionally, it also includes:

[0012] The lifting platform is mounted on the main body.

[0013] A mandrel passes through the receiving cavity, with one end set on the lifting plate and the other end set on the conical platform. The mandrel is used to drive the conical platform to rise and fall after it is raised and lowered.

[0014] Optionally, it also includes:

[0015] There are two guide members, both of which are disposed on the main body. The receiving cavity is located between the two guide members. The two ends of the lifting plate are correspondingly lifted and lowered on the guide members.

[0016] Optionally, it also includes:

[0017] There are two studs, one end of which is threaded onto the guide member, and the other end is rotatably mounted on the lifting plate. When the studs rotate, they are used to drive the lifting plate to rise and fall.

[0018] Optionally, it also includes:

[0019] Two rollers are respectively disposed on one end of the stud, and the rollers are used to drive the stud to rotate.

[0020] Optionally, the rotating component is a telescopic rod, and there are two telescopic rods, which are respectively located at both ends of the lifting plate. One end of the telescopic rod is hinged to the lifting plate, and the other end is hinged to the main body.

[0021] Optionally, it also includes:

[0022] The main body has two dials, which are respectively disposed at both ends of the main body. The dials have scales. The main body has two pointers, which are respectively disposed on the two telescopic rods and point to the scales.

[0024] The working principle and beneficial effects of this utility model are as follows:

[0025] In this invention, the main body has a receiving cavity with an outlet, which is placed at a corresponding position in a glass furnace so that it can receive molten glass flowing out of the furnace. A conical platform is raised and lowered on the main body via a suitable lifting mechanism. By adjusting the position of the conical platform relative to the main body's outlet, different sized forming gaps are formed to meet the production needs of glass tubes of different thicknesses.

[0026] This structural design is simple and direct. The wall thickness of the glass tube is adjusted by the forming gap formed between the conical platform and the main outlet. The forming gap is proportional to the thickness of the glass tube, allowing operators to intuitively control the raising and lowering of the conical platform by pointing a pointer. This enables precise control of the glass tube wall thickness, improving the accuracy and efficiency of adjusting the glass tube wall thickness during production. It also reduces the scrap rate caused by uneven or non-compliant wall thickness, thereby reducing production costs and improving production efficiency. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Reference Figures 1-2This is the first embodiment of the present invention, which proposes a glass tube wall thickness adjustment device for a glass furnace. The main body 1 has a receiving cavity 11 with an outlet 111. The receiving cavity 11 is used to receive molten glass. A conical platform 2 is raised and lowered on the main body 1. The conical platform 2 and the outlet 111 form a forming gap 21. The conical platform 2 is raised and lowered to adjust the size of the forming gap 21. The forming gap 21 is proportional to the thickness of the glass tube. A rotating component is rotated on the main body 1, and a pointer 10 is mounted on the rotating component. The rotation angle of the pointer 10 is proportional to the forming gap 21.

[0035] In this embodiment, the main body 1 has a receiving cavity 11 with an outlet 111, which is placed at a corresponding position in the glass furnace so that the receiving cavity 11 can receive molten glass flowing out of the furnace. The conical platform 2 is raised and lowered on the main body 1 by a suitable lifting mechanism. By adjusting the position of the conical platform 2 relative to the outlet 111 of the main body 1, different sized forming gaps 21 are formed to meet the production needs of glass tubes of different thicknesses.

[0036] This structural design is simple and direct. The wall thickness of the glass tube is adjusted by the forming gap 21 formed between the conical platform 2 and the outlet 111 of the main body 1. The forming gap 21 is proportional to the thickness of the glass tube, which allows the operator to intuitively control the raising and lowering of the conical platform 2 by pointing the pointer 10, thereby accurately controlling the wall thickness of the glass tube. This improves the accuracy and efficiency of adjusting the wall thickness of the glass tube during the production process, reduces the scrap rate caused by uneven wall thickness or non-compliance with requirements, and thus reduces production costs and improves production efficiency.

[0037] Furthermore, the lifting plate 3 is lifted and lowered on the main body 1; the spindle 4 passes through the receiving cavity 11, with one end set on the lifting plate 3 and the other end set on the conical platform 2. After the spindle 4 is lifted and lowered, it is used to drive the conical platform 2 to lift and lower.

[0038] In this embodiment, the lifting plate 3 is raised and lowered on the main body 1 via a guide structure. The spindle 4 passes through the receiving cavity 11 of the main body 1, with one end fixed to the lifting plate 3 and the other end connected to the conical platform 2. When it is necessary to adjust the height of the conical platform 2, an external force is applied to the lifting plate 3 to move it up and down, thereby driving the spindle 4 to move synchronously. The spindle 4 then drives the conical platform 2 to achieve the lifting operation.

[0039] The introduction of the lifting plate 3 and the mandrel 4 makes the lifting and lowering operation of the conical stage 2 more convenient and stable. The mandrel 4, as the component connecting the lifting plate 3 and the conical stage 2, transmits the movement of the lifting plate 3, ensuring the conical stage 2 remains stable during lifting and lowering. This prevents swaying or offset from affecting the uniformity of the forming gap 21, further improving the adjustment accuracy and stability of the glass tube wall thickness, ensuring more reliable glass tube quality, and reducing product quality problems caused by wall thickness errors.

[0040] Furthermore, there are two guide members 5, both of which are set on the main body 1. The receiving cavity 11 is located between the two guide members 5, and the lifting plate 3 is correspondingly lifted and lowered on the guide members 5 at both ends.

[0041] In this embodiment, two guide members 5 are symmetrically mounted on the main body 1, so that the receiving cavity 11 of the main body 1 is located exactly between the two guide members 5. The two ends of the lifting plate 3 are designed to match the structure of the guide members 5, so that it can slide up and down on the guide members 5 accordingly. During the lifting process of the lifting plate 3, the guide members 5 play the role of guiding and restricting the movement direction of the lifting plate 3, so that it can only move up and down along a predetermined vertical direction, preventing tilting or deviation.

[0042] The guide component 5 provides guidance for the lifting movement of the lifting plate 3, ensuring its stability and straightness during the lifting process. This helps ensure the vertical lifting of the mandrel 4 and the conical stage 2, allowing for more precise control of the forming gap 21, thereby improving the consistency and uniformity of the glass tube wall thickness. Simultaneously, it reduces potential malfunctions caused by instability in the lifting plate 3, ensuring the continuity and stability of the production process and improving production efficiency.

[0043] Furthermore, there are two studs 6, one end of which is threaded on the guide 5, and the other end is rotatably mounted on the lifting plate 3. After the studs 6 rotate, they are used to drive the lifting plate 3 to rise and fall.

[0044] In this embodiment, one end of each of the two studs 6 is tightly engaged with the guide member 5 via threads, while the other end is rotatably mounted on the lifting plate 3 via a rotating connection structure (such as a bearing). When it is necessary to adjust the height of the lifting plate 3, a tool (such as a wrench) is used to rotate the studs 6. Due to the threaded engagement between the studs 6 and the guide member 5, the rotational motion of the studs 6 is converted into linear motion on the guide member 5, thereby driving the lifting plate 3 to rise and fall along the guide member 5.

[0045] The threaded drive of stud 6 offers high precision and stability, converting rotary motion into linear motion to achieve fine-tuning of the height of the lifting plate 3. This adjustment capability allows operators to more precisely control the lifting of the conical platform 2, thereby enabling more accurate adjustment of the glass tube wall thickness. Compared to other simple lifting and adjustment methods, the stud 6 drive better meets the requirements for high-precision control of glass tube wall thickness, reduces wall thickness errors, improves product quality, and also facilitates quick and accurate adjustments by operators based on actual production conditions, improving production efficiency and flexibility.

[0046] Furthermore, there are two swing wheels 7, which are respectively set on one end of the stud 6. The swing wheels 7 are used to drive the stud 6 to rotate.

[0047] Furthermore, the rotating component is a telescopic rod 8, with two telescopic rods 8 located at both ends of the lifting plate 3. One end of the telescopic rod 8 is hinged to the lifting plate 3, and the other end is hinged to the main body 1.

[0048] In this embodiment, two telescopic rods 8 are respectively installed at both ends of the lifting plate 3. One end of the telescopic rod 8 is connected to the lifting plate 3 via a hinge structure, allowing it to rotate at a certain angle relative to the lifting plate 3. The other end is also hinged to the main body 1 via a hinge structure, allowing it to rotate relative to the main body 1. During the operation of the device, the telescopic rods 8 extend, retract, and rotate with the lifting plate 3 as it rises and falls, playing a role in assisting support and stabilizing the lifting plate 3, preventing excessive swaying of the lifting plate 3 during the lifting process.

[0049] The telescopic rod 8 can share part of the load borne by the lifting plate 3. At the same time, the telescopic and rotatable characteristics of the telescopic rod 8 enable it to adapt to the posture changes of the lifting plate 3 at different positions, and can support the lifting plate 3 to ensure the smooth lifting of the lifting plate 3.

[0050] Furthermore, there are two dials 9, which are respectively set at both ends of the main body 1. The dials 9 have scales. There are two pointers 10, which are respectively set on the two telescopic rods 8. The pointers 10 point to the scales.

[0051] In this embodiment, two dials 9 are fixedly installed at both ends of the main body 1, making their positions prominent and easy to observe. Two pointers 10 are respectively installed on the two telescopic rods 8, so that they can rotate synchronously with the extension and rotation of the telescopic rods 8. During the lifting process of the lifting plate 3, the pointers 10 will indicate the corresponding positions on the dials 9. The operator can intuitively understand the lifting height of the lifting plate 3 and the position of the conical platform 2 by reading the scale value indicated by the pointers 10, thereby accurately grasping the size of the forming gap 21 and the wall thickness of the glass tube.

[0052] The combination of dial 9 and pointer 10 provides operators with an intuitive and precise means of measurement and monitoring. Operators do not need to rely on complex measuring tools or equipment; they can simply observe the position of pointer 10 on dial 9 to understand the real-time adjustment of the glass tube wall thickness and promptly identify and correct any potential wall thickness deviations. This visual monitoring method not only improves the convenience and accuracy of operation but also helps operators better understand parameter changes during production and optimize the production process.

[0053] Furthermore, the telescopic rod 8 is detachable.

[0054] In this embodiment, at the connection point between the telescopic rod 8 and the lifting plate 3 and the main body 1, the telescopic rod 8 can slide and rotate relative to the lifting plate 3 and the main body 1 within a certain range. When it is necessary to maintain, replace or adjust the telescopic rod 8, the telescopic rod 8 can slide away from the connection point by operating the corresponding unlocking device (such as inserting and removing pins, loosening nuts, etc.) to achieve quick disassembly.

[0055] This sliding and detachable design greatly improves the ease and flexibility of device maintenance. During long-term operation, the telescopic rod 8 may experience wear, damage, or require parameter adjustments. It can be easily disassembled for repair or replacement without requiring large-scale disassembly of the entire device, saving maintenance time and costs.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
