[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] Example 1: Please refer to Figure 1 - Figure 5 , a quartz furnace tube flame polishing device, comprising a base 1, and further comprising:

[0050] The supporting mechanism is arranged inside the base 1 and is provided with a plurality of parts, and is used to support the bottom of the quartz furnace tube and drive the quartz furnace tube to rotate. The supporting mechanism includes a supporting frame 2 arranged inside the base 1 and two driven shafts 3 rotatably connected inside the supporting frame 2; rollers 4 are fixedly sleeved on the outside of the two driven shafts 3;

[0051] First, the staff places the quartz furnace tube on the top of the two rollers 4 in each supporting mechanism, so that the quartz furnace tube is between the two rollers 4 in the same supporting mechanism. The rollers 4 support the quartz furnace tube and drive the two driven shafts 3 in the same supporting mechanism to rotate, thereby driving the corresponding two rollers 4 to rotate synchronously, thereby driving the quartz furnace tube to rotate.

[0052] A driving mechanism is connected to the supporting mechanism and is used to drive the supporting mechanism to operate. The driving mechanism includes a transmission shaft 5 rotatably connected to the outer wall of one side of the supporting frame 2 and a driving shaft 6 rotatably connected to the inner wall of the bottom of the base 1; the two driven shafts 3 and the transmission shaft 5 are both connected through a first transmission member 7, and the first transmission member 7 includes two synchronous wheels fixedly sleeved on the outside of the driven shaft 3 and the transmission shaft 5, and a synchronous belt connected to the outside of the two synchronous wheels; the outside of the driving shaft 6 is slidably sleeved with a sliding sleeve 8, and the outside of the sliding sleeve 8 and the transmission shaft 5 are fixedly sleeved with a bevel gear 9, and the two bevel gears 9 are meshed with each other; the outside of the sliding sleeve 8 is rotatably sleeved with a connecting block 10, and the connecting block 10 is also rotatably sleeved on the outside of the transmission shaft 5. A first motor 11 is installed inside the base 1, and the first motor 11 is connected to one of the drive shafts 6 through a second transmission member 12, and the second transmission member 12 includes two synchronous wheels fixedly sleeved on the outside of the output shaft of the first motor 11 and the outside of the drive shaft 6, and a synchronous belt connected to the outside of the two synchronous wheels; two adjacent drive shafts 6 are connected to each other through a third transmission member 13, and the third transmission member 13 includes two synchronous wheels fixedly sleeved on the outside of the two drive shafts 6, and a synchronous belt connected to the outside of the two synchronous wheels;

[0053] By controlling the first motor 11 to cooperate with the second transmission member 12 to drive one of the driving shafts 6 to rotate, the driving shafts 6 are kept rotating synchronously through the transmission connection of the third transmission members 13. When the driving shaft 6 rotates, the transmission shaft 5 is driven to rotate through the meshing effect between the two bevel gears 9. The two driven shafts 3 are kept rotating through the transmission connection of the two first transmission members 7, thereby driving the two rollers 4 to rotate synchronously, further realizing that the rollers 4 on each support frame 2 rotate at the same speed, thereby driving the quartz furnace tube to rotate stably;

[0054] When the support frame 2 and the roller 4 are raised or lowered, the connecting block 10 is driven to rise or fall synchronously through the transmission shaft 5, thereby driving the sliding sleeve 8 to slide synchronously along the outside of the driving shaft 6, so that the two bevel gears 9 are always kept in meshing state.

[0055] An active adjustment mechanism is connected to the support mechanism and is used to drive the support mechanism to rise and fall. The active adjustment mechanism includes two linkage shafts 14 rotatably connected to the inner wall of the bottom of the base 1 and two linkage blocks 15 respectively fixed to the outer walls of both sides of the support frame 2; the outer parts of the two linkage shafts 14 are fixedly sleeved with reciprocating screws 16, and the linkage blocks 15 are screwed to the outer parts of the reciprocating screws 16; the linkage blocks 15 are also slidably connected to the inner wall of the base 1; the two linkage shafts 14 are connected by a fourth transmission member 17, and the fourth transmission member 17 includes two synchronous wheels respectively fixedly sleeved on the outer parts of the two linkage shafts 14 and a synchronous belt connected to the outer parts of the two synchronous wheels;

[0056] When one of the linkage shafts 14 rotates, the fourth transmission member 17 is used to connect the two linkage shafts 14 so that the two linkage shafts 14 keep rotating synchronously. When the linkage shaft 14 rotates, it drives the reciprocating screw 16 to rotate synchronously, thereby driving the linkage block 15 to rise or fall, thereby driving the roller 4 to rise or fall through the support frame 2, so as to achieve the purpose of controlling the contact and discontinuity between the roller 4 and the quartz furnace tube.

[0057] A polishing mechanism is installed on a base 1 and is used to flame polish the quartz furnace tube in sequence along its length direction. The polishing mechanism includes a screw rod 18 rotatably connected to the inner wall of the base 1, a slider 19 screwed to the outside of the screw rod 18, and a first flame assembly and a second flame assembly installed on the slider 19; a second motor 20 is installed on the outer wall of one side of the base 1, and the output end of the second motor 20 is fixedly connected to one end of the screw rod 18; a guide rod 21 is provided below the screw rod 18, and the guide rod 21 is fixedly connected to the inner wall of the base 1, and the slider 19 is also slidably sleeved on the outside of the guide rod 21. The first flame assembly includes a first flame polishing gun 22 installed inside the slider 19 and a first connecting pipe 23 installed at one end of the first flame polishing gun 22, and the first connecting pipe 23 is connected to the flame host; the first flame polishing gun 22 is arranged along the width direction of the base 1, and is used to flame polish the outer wall of the quartz furnace tube. The second flame assembly includes a slide 24 fixed to the outer wall of one side of the slider 19 and a second flame polishing gun 25 installed inside the slide 24; the slide 24 is slidably connected to the inside of the base 1; the second flame polishing gun 25 is arranged along the height direction of the base 1, and is used to flame polish the inner wall of the quartz furnace tube; one end of the second flame polishing gun 25 is connected to a second connecting pipe 26, and the second connecting pipe 26 is connected to the flame host;

[0058] After the quartz furnace tube is placed, the quartz furnace tube is driven to rotate, and the second motor 20 is controlled to drive the screw rod 18 to rotate, and the slider 19 is driven to move to the left along the outside of the guide rod 21, and the movement is segmented, that is, the slider 19 is driven to pause every time it moves a certain distance. The moving distance is the distance for flame polishing the quartz furnace tube each time. When the slider 19 moves, it drives the first flame polishing gun 22 to move synchronously, and drives the second flame polishing gun 25 to move synchronously through the slide 24. The outer wall and the inner wall of the quartz furnace tube are polished by the first flame polishing gun 22 and the second flame polishing gun 25 respectively;

[0059] The distance between two adjacent support frames 2 is twice the distance the slider 19 moves each time, that is, the slider 19 needs to move to the left twice to move from the position of one support frame 2 to the position of another support frame 2 on its left side.

[0060] The linkage mechanism is connected to the polishing mechanism and is used to sequentially drive each active adjustment mechanism to operate. The linkage mechanism includes a rack 27 fixed to the bottom end of the slider 19 and a gear 28 fixedly sleeved on the outside of one of the linkage shafts 14 in the active adjustment mechanism; the rack 27 is sequentially meshed with the gears 28 in each active adjustment mechanism when moving;

[0061] When the slider 19 moves to the left, it drives the rack 27 to move synchronously, and through the meshing effect between the rack 27 and the gear 28 on one side thereof, it drives the linkage shaft 14 to rotate, and the reciprocating screw 16 rotates synchronously therewith, driving the linkage block 15 to move down from the top end of the reciprocating screw 16 to the bottom end thereof, thereby driving the support frame 2 and the roller 4 to move downward synchronously, so that the roller 4 is separated from the quartz furnace tube, thereby driving the first flame polishing gun 22 and the second flame polishing gun 25 to reach the polishing position in contact with the roller 4, and first driving the roller 4 at this position to descend and separate from the quartz furnace tube, thereby avoiding the problem of deformation of the quartz furnace tube due to the temperature increase when the flame polishing treatment is performed on the contact position with the roller 4;

[0062] When the slider 19 continues to move to the left, the gear 28 and the linkage shaft 14 continue to rotate through the rack 27, and the reciprocating screw 16 continues to rotate, driving the linkage block 15 to move from the bottom end of the reciprocating screw 16 to its top end, thereby driving the support frame 2 and the roller 4 to move up and reset, and the rack 27 and the gear 28 lose engagement, so that the support frame 2 and the roller 4 at this position continue to support and drive the quartz furnace tube. In this cycle, from left to right, according to the polishing positions to be polished by the first flame polishing gun 22 and the second flame polishing gun 25, the rollers 4 in each supporting mechanism are driven down in turn to achieve the effect of not causing deformation of the contact position between the roller 4 and the quartz furnace tube due to temperature conduction.

[0063] The base 1 is also provided with an air cooling mechanism, which includes an air duct 29 installed inside the base 1 and a plurality of shunt pipes 30 installed on the outer wall of the air duct 29, and a solenoid valve is installed on the shunt pipe 30; the support frame 2 is a hollow structure, and the plurality of shunt pipes 30 are respectively connected to the interior of the plurality of support frames 2; a plurality of air holes 31 are opened on the top of the support frame 2, and a telescopic baffle can be set on the left side of the support frame 2 to control the wind direction so that the cold wind does not blow to the flame polishing area on the left side;

[0064] In the process of the support frame 2 and the roller 4 moving up and resetting, the solenoid valve on the shunt pipe 30 connected to the support frame 2 is opened, and cold air is input into the inside of the support frame 2 through the air duct 29 and the shunt pipe 30, and discharged through the air hole 31 at the top of the support frame 2. In conjunction with the rotation of the quartz furnace tube, the area that has just undergone flame polishing is cooled. After the support frame 2 is reset, the solenoid valve is closed.

[0065] Example 2: Please refer to Figure 1 - Figure 5The flame polishing method of quartz furnace tube adopts the flame polishing equipment of quartz furnace tube, and comprises the following steps: firstly, the staff places the quartz furnace tube on the top of two rollers 4 in each supporting mechanism, so that the quartz furnace tube is between the two rollers 4 in the same supporting mechanism, and the rollers 4 play the role of supporting the quartz furnace tube, and the first motor 11 is controlled to cooperate with the second transmission member 12 to drive one of the driving shafts 6 to rotate, and the driving shafts 6 are kept rotating synchronously through the transmission connection of each third transmission member 13. When the driving shaft 6 rotates, the transmission shaft 5 is driven to rotate through the meshing effect between the two bevel gears 9, and the two driven shafts 3 are kept rotating through the transmission connection of the two first transmission members 7, thereby driving the two rollers 4 to rotate synchronously, and further realizing The rollers 4 on each support frame 2 rotate at the same speed, thereby driving the quartz furnace tube to rotate stably. The second motor 20 is controlled to drive the screw rod 18 to rotate, and the slider 19 is driven to move to the left along the outside of the guide rod 21, and the movement is segmented, that is, the slider 19 is driven to pause every time it moves a certain distance. The moving distance is the distance that the quartz furnace tube is flame-polished each time. When the slider 19 moves, it drives the first flame polishing gun 22 to move synchronously, and drives the second flame polishing gun 25 to move synchronously through the slide 24. The outer wall and the inner wall of the quartz furnace tube are polished by the first flame polishing gun 22 and the second flame polishing gun 25 respectively. Among them, when the slider 19 moves to the left, it drives the rack 27 to move synchronously, and the rack 27 is meshed with the gear 28 on one side thereof. The action of the linkage shaft 14 is driven to rotate, and the reciprocating screw 16 rotates synchronously, driving the linkage block 15 to move down from the top end of the reciprocating screw 16 to the bottom end thereof, thereby driving the support frame 2 and the roller 4 to move downward synchronously, so that the roller 4 is separated from the quartz furnace tube, thereby driving the first flame polishing gun 22 and the second flame polishing gun 25 to reach the polishing position in contact with the roller 4, and first driving the roller 4 at this position to descend and separate from the quartz furnace tube, thereby avoiding the problem of deformation of the quartz furnace tube due to temperature increase when the contact position with the roller 4 is flame polished. When the slider 19 continues to move to the left, the gear 28 and the linkage shaft 14 continue to rotate through the rack 27, and the reciprocating screw 16 continues to rotate, driving the linkage block 15 from the reciprocating screw 16 The bottom end of the support frame 2 moves up to its top end, thereby driving the support frame 2 and the roller 4 to move up and reset, and the rack 27 and the gear 28 lose engagement, so that the support frame 2 and the roller 4 at this position continue to support and drive the quartz furnace tube, and in this cycle, from left to right, according to the polishing positions to be polished by the first flame polishing gun 22 and the second flame polishing gun 25, the rollers 4 in each supporting mechanism are driven down in turn, so as to achieve the effect of not causing the contact position between the roller 4 and the quartz furnace tube to be deformed due to heat conduction. In the process of the support frame 2 and the roller 4 moving up and resetting, the solenoid valve on the shunt pipe 30 connected to the support frame 2 is opened, and cold air is input into the support frame 2 through the air duct 29 and the shunt pipe 30, and discharged through the air hole 31 on the top of the support frame 2, in conjunction with the rotation of the quartz furnace tube,To achieve cooling of the area that has just been flame polished.
