Description

Technical Field

[0001] The present invention relates to the field of quartz tube grinding and processing, and specifically relates to a grinding device for quartz tube processing. Background Art

[0002] When the existing dust removal and grinding device for quartz tube processing grinds a quartz tube, it is necessary to grind the inner wall, outer wall and both ends of the quartz tube separately in sequence, and the operation is rather troublesome and time-consuming. Moreover, when the existing grinding device is working, a large amount of debris will be generated, and then the debris will fly, which cannot be collected in time, polluting the working station, and the quartz tube debris cannot be recycled in time, thus causing material waste.

[0003] Chinese Patent CN117428652B discloses a dust removal and grinding device for quartz tube processing, including a processing table. Connecting seats are installed on both the left and right sides of the processing table. A quartz tube inner support grinding mechanism is installed on the left connecting seat, and a quartz tube outer clamping grinding mechanism is arranged on the quartz tube inner support grinding mechanism. After the inner and outer sides of the quartz tube are fixed respectively by switching the quartz tube outer clamping grinding mechanism and the quartz tube inner support grinding mechanism, grinding is carried out; a dust removal mechanism is installed on the right connecting seat, and the dust removal mechanism is arranged outside the quartz tube inner support grinding mechanism. When the quartz tube inner support grinding mechanism operates, it drives the dust removal mechanism to operate to collect the dust generated when grinding the quartz tube.

[0004] Although the above solution can ensure the collection of debris in the quartz tube when grinding the inner wall of the quartz tube, it is only applicable to quartz tubes with open ends at both ends. If one end of the quartz tube is in a closed state, when using the above grinding method, when the grinding device extends into the quartz tube from the open end of the quartz tube, some of the ground debris will accumulate at the sealed end of the quartz tube. This is because the seal of the quartz tube is in a sealed state. When the dust removal mechanism sucks the debris, outside air flows into the quartz tube from between the inner wall of the quartz tube and the grinding device, and then some debris is carried by the flowing air to the sealed end of the quartz tube. Thus, when the grinding device moves to the sealed end of the quartz tube, the debris accumulated on the sealed end of the quartz tube is stirred by the grinding device, scratching the inner wall of the quartz tube. Summary of the Invention

[0005] To address the above problems, a grinding device for quartz tube processing is provided. By setting a grinding rod with an inflation groove and a suction groove on it, the inflation groove inflates the inside of the quartz tube in the grinding state, and the gas filled is sucked out through the suction groove, so that the debris remaining in the quartz tube can be discharged under the action of the air flow. The working principle is as follows. During the rotation of the grinding rod, the debris in the quartz tube drops and accumulates in the quartz tube. At this time, the inflation groove on the inner end of the grinding rod in the quartz tube inflates the quartz tube. Since one end of the quartz tube is closed, when the inflation groove fills the air into the quartz tube, the air will flow from the gap between the grinding rod and the quartz tube towards the opening of the quartz tube. The suction grooves evenly arranged around the inflation groove suck the air flowing from the gap. In this way, the debris accumulated in the quartz tube is discharged from the inside of the quartz tube under the action of the air flow. At the same time, the suction ports of the suction grooves on the side wall of the grinding rod can adsorb the debris, ensuring that the debris will not accumulate in the quartz tube. Furthermore, when the grinding rod grinds the quartz tube through the grinding unit, it is ensured that no debris will mix into the grinding area between the grinding unit and the quartz tube, avoiding the situation that the inner wall of the quartz tube is scratched by the debris during grinding.

[0006] To solve the problems of the prior art, the present invention provides a grinding device for quartz tube processing, including a clamping unit capable of clamping the quartz tube; a grinding rod arranged along the extending direction of the quartz tube after being clamped by the clamping unit. The grinding rod can extend into the quartz tube along the extending direction of the quartz tube. An inflation groove is provided at the end of the grinding rod extending into the quartz tube. A plurality of suction grooves are evenly arranged around the inflation groove. The suction ports of the suction grooves are opened on the side wall of the grinding rod. The inflation groove injects air into the quartz tube, and the suction grooves suck out the injected air and the debris mixed in the air; a grinding unit is provided on the grinding rod. The grinding unit includes a plurality of grinding plates. The grinding plates are evenly arranged around the axis of the grinding rod around the grinding rod. The grinding plates and the suction ports of the suction grooves are arranged staggeredly.

[0007] Preferably, a filtering unit is provided at one end of the suction groove away from the suction port. The filtering unit includes a filter screen. The air drives the debris to pass through the filter screen for filtration and then is discharged, and the debris remains on the filter screen.

[0008] Preferably, the filtering unit includes a filter housing. The filter housing is of an annular housing structure. The filter housing is sleeved on the grinding rod. The filter screen is of an annular structure. The filter screen is arranged in the filter housing. The filter screen divides the filter housing into a filtering chamber and an exhaust chamber. The debris enters the filtering chamber from the suction groove and is intercepted by the filter screen and remains in the filtering chamber. The air filtered by the filter screen is discharged through the exhaust chamber.

[0009] Preferably, a second air pump capable of evacuating the air in the exhaust chamber is provided at the upper part of the exhaust chamber. A bracket is sleeved outside the grinding rod. The grinding rod is rotatably arranged on the bracket. The filter housing is fixedly connected to the bracket.

[0010] Preferably, discharge holes are formed in the peripheral wall of the filter net. The filter net is rotatably arranged in the filter housing. The shielding ring is sleeved on the periphery of the filter net, and the shielding ring is fixedly connected to the inner ring wall of the filter housing through the outer ring side wall. The width of the shielding ring in the extending direction of the polishing rod is smaller than the width of the filter net in the extending direction of the polishing rod. A discharge pipe is vertically arranged at the bottom of the shielding ring. The discharge pipe penetrates out of the bottom of the filter housing. When the filter net rotates, the discharge holes rotate together. The shielding ring shields the discharge holes. When the discharge holes rotate to the directly below position along with the filter net, the discharge holes coincide with the discharge pipe.

[0011] Preferably, a collection bag is sleeved on the lower part of the discharge pipe. The collection bag is used for collecting the debris discharged from the filter cavity. The collection bag is made of a flexible ventilation fabric.

[0012] Preferably, a rotating ring is rotatably arranged at the end of the filter housing facing the suction groove. The inner ring of the rotating ring is fixedly connected to the polishing rod. The rotating ring rotates synchronously with the polishing rod. The two ends of the connecting pipe are respectively connected to the suction groove and the rotating ring. The connection part of the connecting pipe and the rotating ring communicates with the filter cavity.

[0013] Preferably, a driving unit for driving the polishing rod to rotate is arranged at the end of the polishing rod. The driving unit is arranged on the bracket. After the polishing rod extends into the quartz tube, the driving unit is started.

[0014] Preferably, a follower frame is arranged on one side of the filter housing. The follower frame is a rotating body frame structure. The follower frame is fixedly connected to the end of the filter net. The second gear ring is fixedly arranged at the end of the follower frame away from the filter net. When the driving unit is started, the second gear ring is driven to rotate by the driving unit.

[0015] The beneficial effects of the present invention compared with the prior art are:

[0016] The present invention sets a polishing rod, and an inflation groove and a suction groove are arranged on the polishing rod, so that the inflation groove inflates the inside of the quartz tube in the polishing state, and the inflated gas is sucked out through the suction groove, so that the debris remaining in the quartz tube can be discharged under the action of the air flow. The working principle is as follows. During the rotation of the polishing rod, the debris in the quartz tube falls and accumulates in the quartz tube. At this time, the inflation groove on the inner end of the polishing rod in the quartz tube inflates the quartz tube. Since one end of the quartz tube is closed, when the inflation groove fills the air into the quartz tube, the air will flow from the gap between the polishing rod and the quartz tube towards the opening of the quartz tube, and the suction grooves uniformly arranged around the inflation groove suck the air flowing from the gap. In this way, the debris accumulated in the quartz tube is discharged from the inside of the quartz tube under the action of the air flow. At the same time, the suction ports of the suction grooves on the side wall of the polishing rod can adsorb the debris, ensuring that the debris will not accumulate in the quartz tube. Furthermore, when the polishing rod polishes the quartz tube through the polishing unit, it is ensured that no debris will mix into the polishing area between the polishing unit and the quartz tube, avoiding the situation that the inner wall of the quartz tube is scratched by the debris during polishing.

[0030] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific implementation modes.

[0031] Refer to Figures 1 - 5 : A grinding device for quartz tube processing, including a clamping unit 3 capable of clamping a quartz tube 2; including a grinding rod 1 arranged along the extension direction of the quartz tube 2 clamped by the clamping unit 3, the grinding rod 1 can extend into the quartz tube 2 along the extension direction of the quartz tube 2, an inflation groove 11 is opened at the end of the grinding rod 1 extending into the quartz tube 2, a plurality of suction grooves 12 are uniformly arranged around the inflation groove 11, the suction port 121 of the suction groove 12 is opened on the side wall of the grinding rod 1, the inflation groove 11 injects air into the quartz tube 2, and the suction groove 12 sucks out the injected air and the debris mixed in the air.

[0032] A first air pump 13 is provided at the end of the inflation groove 11. The first air pump 13 inflates the inflation groove 11. The clamping unit 3 for clamping the quartz tube 2 is a prior art, so it will not be described in detail here. The debris is quartz debris that falls from the quartz tube 2 during the grinding process of the grinding rod 1. Before grinding the quartz tube 2, the quartz tube 2 needs to be clamped by the clamping unit 3. A moving seat 4 for driving the movement of the grinding rod 1 is provided at the end of the grinding rod 1. After the quartz tube 2 is clamped by the clamping unit 3, the moving seat 4 drives the grinding rod 1 to gradually extend into the quartz tube 2 from the opening of the quartz tube 2 along the extension direction of the quartz tube 2. As the grinding rod 1 enters the quartz tube 2, the grinding rod 1 also starts to rotate. A grinding unit 7 is provided on the side wall of the grinding rod 1. When the grinding rod 1 rotates, it can drive the grinding unit 7 to grind the inner wall of the quartz tube 2. The working principle of the grinding rod 1 being able to completely discharge the debris remaining in the quartz tube 2 during rotary grinding is as follows. During the rotation of the grinding rod 1, the debris in the quartz tube 2 falls and accumulates in the quartz tube 2. At this time, the inflation groove 11 on the inner end of the grinding rod 1 in the quartz tube 2 inflates the quartz tube 2. Since one end of the quartz tube 2 is closed, when the inflation groove 11 fills the air into the quartz tube 2, the air will flow from the gap between the grinding rod 1 and the quartz tube 2 towards the opening of the quartz tube 2. The suction grooves 12 uniformly arranged around the inflation groove 11 suck the air flowing from the gap. In this way, the debris accumulated in the quartz tube 2 is discharged from the inside of the quartz tube 2 under the action of the air flow. At the same time, the suction port 121 of the suction groove 12 on the side wall of the grinding rod 1 can adsorb the debris, ensuring that the debris will not accumulate in the quartz tube 2. Furthermore, when the grinding rod 1 grinds the quartz tube 2 through the grinding unit 7, the debris will not mix into the grinding area between the grinding unit 7 and the quartz tube 2, avoiding the situation that the inner wall of the quartz tube 2 is scratched by the debris during grinding.

[0033] Refer to Figure 3 、 Figure 5 and Figure 10 : A filtering unit 5 is provided at the end of the suction groove 12 away from the suction port 121. The filtering unit 5 includes a filter net 51. The air drives the debris to pass through the filter net 51 for filtering and then is discharged, and the debris remains on the filter net 51.

[0034] Filter holes are uniformly arranged on the filter net 51.

[0035] Refer to Figure 5 and Figure 10: The filtering unit 5 includes a filtering housing 52 which is of an annular housing structure. The filtering housing 52 is sleeved on the grinding rod 1. The filter screen 51 is of an annular structure and is arranged inside the filtering housing 52. The filter screen 51 divides the filtering housing 52 into a filtering chamber 521 and an exhaust chamber 522. Debris enters the filtering chamber 521 from the suction groove 12 and is intercepted by the filter screen 51 and remains in the filtering chamber 521. The air filtered by the filter screen 51 is discharged through the exhaust chamber 522.

[0036] Refer to Figure 6 and Figure 10 : A second air pump 523 capable of pumping out the air in the exhaust chamber 522 is arranged at the upper part of the exhaust chamber 522. A bracket 524 is sleeved on the periphery of the grinding rod 1. The grinding rod 1 is rotatably arranged on the bracket 524. The filtering housing 52 is fixedly connected to the bracket 524.

[0037] The end of the moving seat 4 is fixedly connected to the bracket 524. The bracket 524 does not rotate with the grinding rod 1, and the filtering housing 52 is fixedly arranged on the bracket 524. In this way, it is ensured that when the grinding rod 1 rotates, the filtering housing 52 does not rotate with the grinding rod 1 either, so that the second air pump 523 arranged on the exhaust chamber 522 is always located on the upper side of the exhaust chamber 522. The second air pump 523 starts before the grinding rod 1 extends into the quartz tube 2. The first air pump 13 and the second air pump 523 start at the same time. The first air pump 13 fills the quartz tube 2 with gas through the inflation groove 11, and the second air pump 523 pumps out the gas in the quartz tube 2 through the suction groove 12, so as to form a circulating air flow in the quartz tube 2, and the flow direction of the air flow is towards the opening of the quartz tube 2. However, the air flow is sucked by the suction groove 12 when it passes through the suction port 121 of the suction groove 12. In this way, it can be ensured that when the grinding rod 1 grinds the quartz tube 2, the debris ground off can be smoothly discharged.

[0038] Refer to Figure 10 : Discharge holes 511 are formed in the peripheral wall of the filter screen 51. The filter screen 51 is rotatably arranged in the filtering housing 52. A shielding ring 53 is sleeved on the periphery of the filter screen 51 and the shielding ring 53 is fixedly connected to the inner ring wall of the filtering housing 52 through the outer ring side wall. The width of the shielding ring 53 in the extending direction of the grinding rod 1 is smaller than the width of the filter screen 51 in the extending direction of the grinding rod 1. A discharge pipe 531 is vertically arranged at the bottom of the shielding ring 53. The discharge pipe 531 penetrates out from the bottom of the filtering housing 52. When the filter screen 51 rotates, the discharge holes 511 rotate together. The shielding ring 53 shields the discharge holes 511. When the discharge holes 511 rotate to the directly below with the filter screen 51, the discharge holes 511 coincide with the discharge pipe 531.

[0039] The suction groove 12 sucks debris into the filtering cavity 521. The filter net 51 filters the air mixed with debris, causing the debris to remain in the filtering cavity 521, and the air is discharged through the exhaust cavity 522. The shielding ring 53 sleeved around the periphery of the filter net 51 is used to shield the discharge holes 511 on the filter net 51. That is, when the discharge holes 511 on the filter net 51 are not directly below the filter net 51, the debris accumulated in the filtering cavity 521 cannot be discharged, and by continuously rotating the filter net 51 in the filter housing 52, the discharge holes 511 on the rotating filter net 51 can be made to coincide with the discharge pipe 531. When the discharge holes 511 coincide with the discharge pipe 531, the debris accumulated in the filtering cavity 521 can be discharged. It should be noted that a collection bag 54 for collecting debris is provided at the lower part of the discharge pipe 531. When the discharge holes 511 on the filter net 51 and the discharge pipe 531 are in a staggered state, even air in the filtering cavity 521 cannot enter the collection bag 54.

[0040] Refer to Figure 5 and Figure 10 : A collection bag 54 is sleeved at the lower part of the discharge pipe 531. The collection bag 54 is used to collect the debris discharged from the filtering cavity 521, and the collection bag 54 is made of a flexible breathable fabric.

[0041] A collection bag 54 is provided at the lower part of the discharge pipe 531 to collect the debris discharged from the filtering cavity 521. By selecting a flexible breathable fabric as the material of the collection bag 54, it can ensure that when the discharge holes 511 on the filter net 51 coincide with the discharge pipe 531, the debris in the filtering cavity 521 can be normally discharged, and at the same time, there will be no situation of flowing back into the filtering cavity 521. This is because the collection bag 54 has air permeability. After the discharge holes 511 coincide with the discharge pipe 531, the debris and part of the air flow in the filtering cavity 521 will enter the collection bag 54. Due to the air permeability of the collection bag 54, the air flow can be discharged from the collection bag 54, thus avoiding the phenomenon of air flow flowing back in the collection bag 54 and raising the debris collected in the collection bag 54. If the collection bag 54 is made of an airtight material, the air flow entering the collection bag 54 along with the debris will raise the debris accumulated in the collection bag 54, and then the debris will re-enter the filtering cavity 521. By setting the collection bag 54 as a flexible breathable fabric, the above situation can be avoided.

[0042] Refer to Figure 5 : A rotating ring 55 is rotatably provided at the end of the filter housing 52 facing the suction groove 12. The inner ring of the rotating ring 55 is fixedly connected to the polishing rod 1, and the rotating ring 55 rotates synchronously with the polishing rod 1. Both ends of the connecting pipe 56 are connected to the suction groove 12 and the rotating ring 55 respectively, and the connection part of the connecting pipe 56 and the rotating ring 55 is communicated with the filtering cavity 521.

[0043] Since there are multiple suction grooves 12, there are also multiple connecting pipes 56 for discharging the debris sucked in the suction grooves 12 into the filter chamber 521. When the polishing rod 1 rotates, the connecting pipes 56 rotate synchronously with the polishing rod 1. To ensure that the connecting pipes 56 will not be damaged due to collision when rotating with the polishing rod 1, a follower sleeve 57 is fixedly arranged at one end of the rotating ring 55 facing the suction groove 12, and the follower sleeve 57 wraps all the connecting pipes 56.

[0044] Refer to Figure 10 and Figure 11 : A driving unit 6 for driving the rotation of the polishing rod 1 is arranged at the end of the polishing rod 1. The driving unit 6 is arranged on the support 524. After the polishing rod 1 extends into the quartz tube 2, the driving unit 6 is started.

[0045] The driving unit 6 includes a rotary driver 61, a gear 62 and a first toothed ring 63. The rotary driver 61 is fixedly arranged on the support 524. The gear 62 is fixedly arranged on the output end of the rotary driver 61. The first toothed ring 63 is fixedly arranged along the axis of the polishing rod 1 at the end of the polishing rod 1. The polishing rod 1 passes through the support 524 and is rotationally matched with the support 524. The moving seat 4 is fixedly connected with the support 524. The first toothed ring 63 meshes with the gear 62. The rotary driver 61 is preferably a servo motor. After the clamping unit 3 clamps the quartz tube 2, the moving seat 4 drives the polishing rod 1 to extend into the quartz tube 2 from the opening of the quartz tube 2 through the support 524. Subsequently, the rotary driver 61 is started, and the rotary driver 61 drives the gear 62 to rotate. Since the gear 62 meshes with the first toothed ring 63 and the first toothed ring 63 is fixedly connected with the end of the polishing rod 1, the polishing rod 1 can be driven to rotate in this way.

[0046] Refer to Figure 10 : A follower frame 59 is arranged on one side of the filter housing 52. The follower frame 59 is a rotating body frame structure. The follower frame 59 is fixedly connected with the end of the filter net 51. The second toothed ring 58 is fixedly arranged at one end of the follower frame 59 away from the filter net 51. When the driving unit 6 is started, the second toothed ring 58 is driven to rotate by the driving unit 6.

[0047] The second toothed ring 58 is rotatably arranged on the support 524. The second toothed ring 58 is sleeved outside the first toothed ring 63. Both sides of the gear 62 mesh with the first toothed ring 63 and the second toothed ring 58 respectively. In this way, when the rotary driver 61 is started, the rotary driver 61 can drive the second toothed ring 58 to rotate while driving the first toothed ring 63 to rotate through the gear 62. The second toothed ring 58 drives the filter net 51 to rotate through the follower frame 59. In this way, when the discharge holes 511 on the filter net 51 do not coincide with the discharge pipe 531, the air containing debris entering the filter chamber 521 can be filtered through the filter net 51, and the filtered air enters the exhaust chamber 522 and is discharged.

[0048] Reference Figure 4 and Figures 7 - 9 : A grinding unit 7 is provided on the grinding rod 1. The grinding unit 7 includes a plurality of grinding plates 71. The grinding plates 71 are uniformly arranged around the axis of the grinding rod 1 and are staggered with the suction ports 121 of the suction grooves 12.

[0049] The grinding unit 7 further includes a pushing frame 72, a third air pump 73, a pushing groove 74, a connecting rod 75, a sliding groove 76, a groove 77 and a support column 78. The groove 77 is opened on the side wall of the grinding rod 1 along the extending direction of the grinding rod 1. The support column 78 is fixedly arranged in the groove 77 along the width direction of the groove 77. The pushing frame 72 is movably arranged in the groove 77 along the extending direction of the groove 77. The pushing frame 72 is located below the support column 78. The two ends of the connecting rod 75 are respectively hinged to the pushing frame 72 and the grinding plate 71. The sliding groove 76 is opened on the connecting rod 75 along the length direction of the connecting rod 75. The support column 78 passes through the sliding groove 76, and the support column 78 is slidably matched with the sliding groove 76 along the extending direction of the sliding groove 76. The pushing groove 74 is arranged at the end of the groove 77. The third air pump 73 is arranged on the pushing groove 74. When the third air pump 73 inflates the pushing groove 74, the pushing frame 72 slides out of the pushing groove 74, and the pushing frame 72 slides in the groove 77, so that the connecting rod 75 unfolds, thus changing the distance between the grinding plate 71 and the grinding rod 1, enabling the grinding plate 71 to adapt to quartz tubes 2 with different inner diameters.

[0050] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
