Technical Field

[0001] The utility model relates to the technical field of quartz mother tube heating equipment, in particular to a quartz mother tube hanging bracket and a curvature and roundness adjustment system thereof. Background Art

[0002] At present, the quartz tubes stretched out by the quartz mother tube through the high temperature stretching furnace have many problems of excessive curvature and roundness geometric parameters, which greatly reduces the qualified rate of quartz tubes. In order to avoid the above problems, it is necessary to timely adjust the quartz mother tubes that deviate from the core high temperature area of ​​the heating components of the stretching furnace to improve the curvature and roundness of the stretched quartz tubes.

[0003] At present, this work can only be completed through manual adjustment. However, there are great uncontrollable factors in the manual adjustment of the qualified rate of finished products. The uncontrollable factors are as follows: 1. At present, it can only be determined based on the test results of the curvature and roundness of the stretched quartz tube to determine whether the quartz mother tube needs to be adjusted in the core high temperature area of ​​the stretching furnace, and manual adjustment can only rely on personal experience to judge the adjustment size and direction, resulting in great inaccuracy in the results of manual adjustment; 2. During the period between the judgment of the need for adjustment and the start of manual adjustment, the quartz tubes produced have exceeded the standard or even been scrapped due to the excessive geometric parameters of curvature and roundness, and there is a serious adjustment lag; 3. During the manual adjustment process, the quartz mother tube is completely exposed and suspended above the head of the operator without protective facilities, and the high temperature of the stretching furnace is also a great source of scalding danger, and manual adjustment is extremely unsafe. 4. There are uncontrollable factors such as uneven temperature in the hot zone of the heating components inside the stretching furnace or the bending of the mother tube itself. Therefore, special equipment is urgently needed to adjust the quartz mother tube. Utility Model Content

The quartz mother tube is provided with two annular grooves, one of which is adapted to the support frame 4 and the other is adapted to the safety snap ring 5. The installation snap ring is used to ensure double insurance support for the quartz mother tube, thereby ensuring the safety of its suspension.

[0029] Further, refer to Figure 2 The quartz mother tube suspension bracket also includes a moving plate 11 connected to the supporting top plate 41, the lateral moving mechanism includes a lateral moving slider 14 fixed under the moving plate 11 (four lateral moving sliders 14 are provided to stably support the sliding of the moving plate 11), and the mounting seat 1 includes a first supporting plate 12, and a lateral slide rail adapted to the lateral moving slider 14 is installed on the first supporting plate 12.

[0031] The lateral moving slider 14 and the longitudinal moving slider 15 are both equipped with a driving mechanism 9 to drive them to move. The driving mechanism 9 is also equipped with a signal transmission receiver. The driving mechanism 9 can be a motor.

[0032] The signal transmission receiver is used to receive the signal sent by the controller, so as to control the specific moving distance of the transverse moving slider 14 and the longitudinal moving slider 15 to ensure that the quartz mother tube is always located in the core high temperature area of ​​the stretching furnace 30.

[0033] Furthermore, the supporting top plate 41 and the movable plate 11 can be detachably connected to adjust their installation positions. The two can be detachably connected via fasteners.

[0034] In this embodiment, the support frame includes a top plate 41 and a bottom plate 42 arranged opposite to each other, and a side plate 43 (three side plates 43 are provided) connecting the top plate 41 and the bottom plate 42, wherein a groove for matching with the annular groove of the quartz mother tube is provided on the bottom plate 42.

[0035] Furthermore, the support frame also includes a sealing plate 44 which is located on the bottom plate 42 and can be opened and closed. The sealing plate 44 seals the open side of the slot of the bottom plate 42 .

During the entire stretching process, when the electronic signal transmission receiver receives the accurate position and value signal of the quartz mother tube deviating from the core high temperature zone issued by the electronic test system 7, the electronic signal transmission receiver will send a position movement instruction, and complete the corresponding front, back, left, and right position movement through the corresponding slider movement, so as to achieve the purpose of adjusting the quartz mother tube to always be in the core high temperature zone of the heating component.

[0037] The quartz mother tube hanging bracket proposed in this embodiment adjusts the position of the quartz mother tube inside the stretching furnace 30 through a lateral moving mechanism and a longitudinal moving mechanism to ensure that it is always in the core high temperature zone, which can solve the problems of inaccurate manual adjustment and high temperature burns.

The specific structure and beneficial effects of the quartz mother tube suspension bracket refer to the above embodiment and will not be repeated here. In order to prevent gas blowby, a circle of sealing material is filled between the quartz mother tube and the quartz ring 10.

[0040] The electronic test system 7 is connected to an infrared thermal imager system 20, and the external thermal imager system continuously transmits the specific position of the core high temperature zone of the heating component to the electronic test system 7. The electronic test system 7 transmits the accurate position and value of the quartz mother tube's deviation from the core high temperature zone to the control system and the quartz ring linkage cylinder system 6 in real time, and the control system then sends the corresponding movement instruction to the electronic signal transmission receiver to always keep the quartz mother tube in the core high temperature zone of the heating component. The quartz ring linkage cylinder system 6 also fine-tunes the displacement of the quartz ring 10 in real time according to the deviation data to prevent gas blowby of the quartz ring 10.
