Description

Technical Field

[0001] This invention relates to the field of glass production technology, and in particular to a ring-cutting device for producing high borosilicate glass tubes. Background Technology

[0002] Glass tubes are a type of non-metallic tube, made primarily of sodium oxide, boron oxide, and silicon dioxide. Their superior performance has been widely recognized worldwide. Compared to ordinary glass, they are non-toxic and have significantly improved mechanical properties, thermal stability, water resistance, alkali resistance, and acid resistance. They can be widely used in chemical, aerospace, military, household, and hospital applications, demonstrating significant promotional value and social benefits. In the manufacturing process of glass tubes, the formed tubes are conveyed horizontally forward parallel to their length by a transport device. During this process, a cutting structure cuts the glass tube into several standard segments, which are then manually placed one by one onto a belt conveyor.

[0003] There are generally two methods for cutting glass tubes: one is to break the glass filament by impact, which is more suitable for glass tubes with smaller diameters; the other is to cut the glass tube by circumferential cutting, which is more suitable for glass tubes with larger diameters. However, when circumferentially cutting a glass tube, the cutting blade needs to be in direct contact with the glass tube. After the first cut, the conveying device needs to convey the glass tube to a fixed length. At this time, the cutting blade needs to leave the end face of the glass tube to avoid the blade and the glass tube obstructing each other. The movement trajectory of the cutting device is relatively complicated, which affects its cutting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a circumferential cutting device for the production of high borosilicate glass tubes, which solves the problem in the prior art that after the cutting is completed, the cutting blade needs to leave the end face of the glass tube to avoid the blade and the glass tube blocking each other, and the movement trajectory of the cutting device is cumbersome, thus affecting its cutting efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ring-cutting device for producing high borosilicate glass tubes, comprising a housing, a guide assembly disposed in front of the housing, and a cutter mounted on the guide assembly. The housing has a through-hole in the middle for glass tubes to enter and exit. A rotating groove is provided in front of the housing. The guide assembly includes a servo motor disposed inside the upper part of the housing. The output end of the servo motor extends to the front of the housing and is fixedly connected to a spur gear. The guide assembly also includes a rotating ring rotatably connected in the rotating groove. A gear ring is rotatably connected to the outside of the rotating ring, and the gear ring meshes with the spur gear. A reverse locking mechanism is provided in front of the housing, located inside the rotating ring, to prevent the rotating ring from rotating in the opposite direction.

[0006] The guide assembly also includes a mounting plate movably disposed at the front of the housing, the cutting machine is mounted on the mounting plate, a first slider is disposed at the rear of the mounting plate, a first sliding groove is disposed at the front of the rotating ring, the first slider is slidably connected in the first sliding groove, a second guide post is fixedly connected at the rear of the mounting plate, an inclined groove corresponding to the second guide post is disposed on the gear ring, a first guide post is fixedly connected at the top of the mounting plate, and a guide groove and a moving groove corresponding to the first guide post are disposed at the front of the housing, with the moving groove located above the guide groove and communicating with the guide groove;

[0007] The servo motor drives the spur gear to rotate, which in turn drives the gear ring to rotate clockwise. As the gear ring rotates clockwise, the mounting plate moves downward under the guidance of the inclined groove and the second guide post. At this time, the first slider moves downward in the first slide groove, and the first guide post enters the guide groove from the moving groove. Subsequently, as the gear ring rotates, it drives the rotating ring to rotate through the inclined groove, the second guide post, the mounting plate, the first slider, and the first slide groove. The rotating ring, the mounting plate, and the cutting machine revolve around the glass tube, and the cutting machine performs a ring cut. After one cut, the servo motor drives the spur gear to rotate in the opposite direction. Under the action of the reverse locking mechanism, the inclined groove guides the second guide post, and the mounting plate moves upward away from the end face of the glass tube, after which the glass tube can be transported.

[0008] Furthermore, a second sliding groove is provided at the front of the interior of the mounting plate, and a second slider is slidably disposed inside the second sliding groove. The front of the second slider is fixedly connected to the cutting machine via a mounting bracket.

[0009] Furthermore, the mounting plate is internally rotatably equipped with an adjusting screw, and one end of the adjusting screw extends downward to the bottom of the mounting plate. The adjusting screw is threadedly connected to the second slider.

[0010] Furthermore, a fixing ring is installed at the front of the outer casing, and a conductive ring is provided on the inner side of the fixing ring. There are two sets of conductive rings, which are respectively connected to the positive and negative poles. A movable sleeve is installed on the top of the cutting machine. The movable sleeve is a component made of two sets of sleeves that are slidably connected. A conductive slider is fixedly connected to the top of the movable sleeve. The conductive slider is slidably connected to the inner side of the fixing ring. The positive and negative pole wires of the cutting machine pass through the movable sleeve and are electrically connected to the conductive ring on the inner side of the fixing ring through the conductive slider.

[0011] Furthermore, the reverse locking mechanism includes a slot disposed inside the rotating ring, the slot having a right-angled triangular cross-section. The reverse locking mechanism also includes a fixing block fixedly connected to the surface of the outer shell. A locking block is slidably connected to the upper part of the fixing block, the locking block corresponding to the slot, the locking block having a right-angled trapezoidal cross-section. A spring is disposed between the bottom of the locking block and the bottom inner wall of the fixing block. Through the cooperation of the locking block and the slot, the rotating ring can only rotate clockwise and cannot rotate counterclockwise. When the gear ring rotates counterclockwise, the mounting plate moves upward under the guidance of the first sliding groove, the first slider, the inclined groove, and the second guide post.

[0012] Furthermore, the interior of the outer casing is provided with a conveying mechanism for conveying the glass tube, and the interior of the outer casing is also provided with support rollers for supporting the glass tube.

[0013] Furthermore, the support rollers are arranged in two sets on both sides of the inner side of the outer casing, with three rollers in each set. The support rollers are components consisting of a telescopic cylinder and a transmission roller rotatably connected to the output end of the telescopic cylinder.

[0014] Furthermore, the conveying mechanism includes a reciprocating motion mechanism and guide clamping mechanisms disposed on both sides below the reciprocating motion mechanism. The reciprocating motion mechanism includes a geared motor fixedly installed inside the upper part of the housing, and a sector gear fixedly connected to the output end of the geared motor. The reciprocating motion mechanism also includes a movable ring slidably connected to the upper part of the housing. The inner side of the movable ring is provided with tooth grooves corresponding to the sector gears. Fixed frames are fixedly connected to both sides of the movable ring. When the geared motor drives the sector gear to rotate, the sector gear meshes with the tooth grooves back and forth, which can drive the movable ring to reciprocate back and forth inside the housing. When the movable ring moves backward, it clamps and conveys the glass tube through the clamping guide mechanism. When the movable ring moves forward, this is the reset process of the clamping guide mechanism.

[0015] Furthermore, the guiding clamping mechanism includes guide plates fixedly disposed on both sides inside the housing. The guide plates have a movable inner cavity inside and an opening at the top. The top of the guide plates is also provided with a longitudinal third sliding groove. A first baffle and a second baffle are slidably disposed on both sides inside the movable inner cavity. Compression springs are installed between the first baffle and the second baffle and the inner wall of the guide plate. The guiding clamping mechanism also includes a first guide block and a second guide block fixedly disposed inside the guide plates.

[0016] Furthermore, the guide clamping mechanism also includes a third guide block movably disposed inside the guide plate. The cross-sections of the third guide block, the first guide block, and the second guide block are all parallelograms. A guide frame is fixedly connected to the bottom of the fixed frame, and a movable groove is provided on the guide frame. Clamps are also movably disposed between the two sets of guide plates. The clamps include an adjusting frame, one end of which passes through the movable groove via a shaft and is fixedly connected to the third guide block. A third slider is slidably connected to the middle of the adjusting frame, and the third slider is slidably connected in the third sliding groove. The clamps also include a clamping block disposed at the other end of the adjusting frame. The clamping block is installed with the adjusting frame via an adjusting nut. When the movable ring moves backward, the third guide block moves from right to left. The third guide block is guided by the edge of one end of the first guide block and slides between the first guide block and the first baffle. At this time, due to... The third guide block moves from the end that is attached to the first guide block to the space between the first guide block and the first baffle. The two sets of clamps are in a clamping state and drive the glass tube to move until the third guide block moves to the space between the second guide block and the first baffle. Then, when the third guide block moves from left to right, the third guide block leaves the limit of the second guide block. Under the action of the first baffle and its return spring, the edge of the third guide block is attached to the edge of the first guide block near the second guide block. Under its guidance, the third guide block enters the space between the second baffle and the first guide block along the edge of the first guide block. At this time, it is not in a clamping state. When the third guide block moves to the other end of the first guide block, under the push of the second baffle and its return spring, the third guide block is attached to the edge of the first guide block away from the second guide block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention provides a ring-cutting device for producing high borosilicate glass tubes. A servo motor and spur gear drive a gear ring to rotate. When the gear ring rotates clockwise, the inclined groove presses against the first guide post, causing the mounting plate to move downwards. This allows the rotating blade on the cutting machine to cut the glass tube. Subsequently, the gear ring continues to rotate, driving the mounting plate, the cutting machine, and the rotating ring to rotate, thus performing ring cutting. After one revolution, the servo motor and spur gear drive the gear ring to rotate in the opposite direction. At this time, a reverse locking mechanism limits the rotating ring in the reverse direction. Guided by the inclined groove, the mounting plate and the cutting machine move upwards, separating the blade from the cutting surface. This guides the movement of the cutting machine, preventing the blade from obstructing the glass tube transport. The device is easy to operate and has high cutting efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To address the technical problem of the cutting device's complex movement trajectory, which affects cutting efficiency, after the cutting blade needs to leave the end face of the glass tube following cutting, and to prevent the blade and glass tube from obstructing each other, the following measures are taken: Figures 1-9 As shown, the following preferred technical solutions are provided:

[0031] like Figure 1 As shown, a ring-cutting device for producing high borosilicate glass tubes includes a housing 1, a guide assembly 2 disposed in front of the housing 1, and a cutter 3 mounted on the guide assembly 2. The housing 1 has a through-hole in the middle for the glass tube to enter and exit. Figure 2-6 As shown, a rotating groove 17 is provided at the front of the outer casing 1. The guide assembly 2 includes a servo motor 21 located inside the upper part of the outer casing 1. The output end of the servo motor 21 extends to the front of the outer casing 1 and is fixedly connected to a spur gear 22. The guide assembly 2 also includes a rotating ring 23 rotatably connected in the rotating groove 17. A gear ring 24 is rotatably connected to the outside of the rotating ring 23, and the gear ring 24 meshes with the spur gear 22. A reverse locking mechanism 25 is provided at the front of the outer casing 1 on the inner side of the rotating ring 23. The reverse locking mechanism 25 is used to prevent the rotating ring 23 from rotating in the reverse direction.

[0032] The guide assembly 2 also includes a mounting plate 26 movably disposed in front of the housing 1. The cutting machine 3 is mounted on the mounting plate 26. A first slider 29 is disposed behind the mounting plate 26. A first slide groove 231 is disposed in front of the rotating ring 23. The first slider 29 is slidably connected in the first slide groove 231. A second guide post 28 is also fixedly connected to the rear of the mounting plate 26. A slanted groove 241 corresponding to the second guide post 28 is disposed on the gear ring 24. A first guide post 27 is also fixedly connected to the top of the mounting plate 26. A guide groove 11 and a moving groove 12 corresponding to the first guide post 27 are disposed in front of the housing 1. The moving groove 12 is located above the guide groove 11 and communicates with the guide groove 11.

[0033] The servo motor 21 drives the spur gear 22 to rotate, which in turn drives the gear ring 24 to rotate clockwise. As the gear ring 24 rotates clockwise, the mounting plate 26 moves downward under the guidance of the inclined groove 241 and the second guide post 28. At this time, the first slider 29 moves downward in the first slide groove 231, and the first guide post 27 moves from the moving groove 12 into the guide groove 11. Subsequently, as the gear ring 24 rotates, the inclined groove 241, the second guide post 28, the mounting plate 26, the first slider 29, and the first slide groove 231 drive the rotating ring 23 to rotate. The rotating ring 23, the mounting plate 26, and the cutting machine 3 revolve around the glass tube. Under the action of the cutting machine 3, a ring cut is performed. After one cut, the servo motor 21 drives the spur gear 22 to rotate in the opposite direction. Under the action of the reverse locking mechanism 25, the inclined groove 241 guides the second guide post 28, and the mounting plate 26 moves upward away from the end face of the glass tube. Then, the glass tube can be transported.

[0034] like Figure 6 As shown, a second slide groove 261 is provided at the front of the interior of the mounting plate 26, and a second slider 262 is slidably disposed inside the second slide groove 261. The front of the second slider 262 is fixedly connected to the cutting machine 3 through the mounting bracket 264.

[0035] like Figure 6 As shown, an adjusting screw 263 is rotatably installed inside the mounting plate 26, and one end of the adjusting screw 263 extends downward to the bottom of the mounting plate 26. The adjusting screw 263 is threadedly connected to the second slider 262. The position of the cutting machine 3 can be adjusted by adjusting the screw 263 to adapt to the cutting of proportional tubes of different diameters.

[0036] like Figure 3-4 As shown, a fixing ring 13 is installed at the front of the outer casing 1, and a conductive ring 14 is provided on the inner side of the fixing ring 13. There are two sets of conductive rings 14, which are respectively connected to the positive and negative poles. A movable sleeve 16 is installed on the top of the cutting machine 3. The movable sleeve 16 is a component made of two sets of slidingly connected sleeves. A conductive slider 15 is fixedly connected to the top of the movable sleeve 16. The conductive slider 15 is slidably connected to the inner side of the fixing ring 13. The positive and negative pole wires of the cutting machine 3 pass through the movable sleeve 16 and are electrically connected to the conductive ring 14 on the inner side of the fixing ring 13 through the conductive slider 15.

[0037] like Figure 5As shown, the reverse locking mechanism 25 includes a slot 254 disposed inside the rotating ring 23. The slot 254 has a right-angled triangular cross-section. The reverse locking mechanism 25 also includes a fixing block 251 fixedly connected to the surface of the outer shell 1. A locking block 253 is slidably connected to the upper part of the fixing block 251. The locking block 253 corresponds to the slot 254. The cross-section of the locking block 253 is a right-angled trapezoid. A spring 252 is disposed between the bottom of the locking block 253 and the bottom inner wall of the fixing block 251. Through the cooperation of the locking block 253 and the slot 254, the rotating ring 23 can only rotate clockwise and cannot rotate counterclockwise. When the gear ring 24 rotates counterclockwise, the mounting plate 26 moves upward under the guidance of the first sliding groove 231, the first slider 29, the inclined groove 241 and the second guide post 28.

[0038] like Figure 7 As shown, the housing 1 is equipped with a conveying mechanism 4 for conveying glass tubes, and the housing 1 is also equipped with a support roller 5 for supporting the glass tubes.

[0039] The support rollers 5 are arranged in two sets on both sides inside the outer casing 1, with three rollers in each set. The support rollers 5 are components consisting of a telescopic cylinder and a transmission roller rotatably connected to the output end of the telescopic cylinder.

[0040] like Figure 8 As shown, the conveying mechanism 4 includes a reciprocating motion mechanism and guide clamping mechanisms disposed on both sides below the reciprocating motion mechanism. The reciprocating motion mechanism includes a geared motor 41 fixedly installed inside the upper part of the outer casing 1. A sector gear 42 is fixedly connected to the output end of the geared motor 41. The reciprocating motion mechanism also includes a movable ring 43 slidably connected to the upper part of the outer casing 1. The inner side of the movable ring 43 is provided with a tooth groove 431 corresponding to the sector gear 42. Fixed brackets 432 are fixedly connected to both sides of the movable ring 43. When the geared motor 41 drives the sector gear 42 to rotate, the sector gear 42 meshes with the tooth groove 431 back and forth, which can drive the movable ring 43 to reciprocate back and forth inside the outer casing 1. When the movable ring 43 moves backward, it clamps and conveys the glass tube through the clamping guide mechanism. When the movable ring 43 moves forward, this is the reset process of the clamping guide mechanism.

[0041] like Figure 9 As shown, the guide clamping mechanism includes guide plates 44 fixedly disposed on both sides inside the housing 1. The guide plates 44 have a movable inner cavity 441 inside and an opening at the top. The top of the guide plates 44 also has a longitudinal third slide groove 442. A first baffle 443 and a second baffle 444 are slidably disposed on both sides inside the movable inner cavity 441. Compression springs are installed between the first baffle 443 and the second baffle 444 and the inner wall of the guide plates 44. The guide clamping mechanism also includes a first guide block 45 and a second guide block 46 fixedly disposed inside the guide plates 44.

[0042] like Figure 9 As shown, the guide clamping mechanism also includes a third guide block 49 movably disposed inside the guide plate 44. The cross-sections of the third guide block 49, the first guide block 45, and the second guide block 46 are all parallelograms. A guide frame 47 is fixedly connected to the bottom of the fixed frame 432. A movable groove 471 is provided on the guide frame 47. Clamps 48 are also movably disposed between the two sets of guide plates 44. The clamps 48 include an adjusting frame 481. One end of the adjusting frame 481 passes through the movable groove 471 via a shaft and is fixedly connected to the third guide block 49. A third slider 482 is slidably connected to the middle of the adjusting frame 481. The third slider 482 is slidably connected in the third sliding groove 442. The clamps 48 also include a clamping block 483 disposed at the other end of the adjusting frame 481. The clamping block 483 is installed with the adjusting frame 481 by an adjusting nut 484. Figure 9 As shown, when the movable ring 43 moves backward, the third guide block 49 moves from right to left. The third guide block 49 is guided by one edge of the first guide block 45 and slides between the first guide block 45 and the first baffle 443. At this time, since the third guide block 49 moves from the end that is attached to the first guide block 45 to between the first guide block 45 and the first baffle 443, the two sets of clamps 48 are in a clamping state and drive the glass tube to move until the third guide block 49 moves to the position between the second guide block 46 and the first baffle 443. Then, when the third guide block 49 moves from left to right, the third guide block 49 moves from right to left. 9. After leaving the limit of the second guide block 46, and under the action of the first baffle 443 and its return spring, the edge of the third guide block 49 is in contact with the edge of the first guide block 45 near the end of the second guide block 46. Under its guidance, the third guide block 49 enters between the second baffle 444 and the first guide block 45 along the edge of the first guide block 45. At this time, it is not in a clamping state. Until the third guide block 49 moves to the other end of the first guide block 45, under the push of the second baffle 444 and its return spring, the third guide block 49 is in contact with the edge of the first guide block 45 away from the end of the second guide block 46.

[0043] Working Principle: First, the glass tube is transported and cut by adjusting the position of the conveying mechanism 4. During the transport process, the moving ring 43 is driven to move from the rear to the front inside the outer casing 1 by the reduction motor 41 and the sector gear 42. As the fixed frame 432 drives the guide frame 47 to move, the guide frame 47 drives the third guide block 49 to move from the end of the first guide block 45 away from the second guide block 46. During the movement, the third guide block 49 enters between the first guide block 45 and the first baffle 443. The movement of the third guide block 49 causes the clamp 48 to clamp the glass tube, driving the glass tube to move until the third guide block 49 moves between the second guide block 46 and the first baffle 443. At this time, the glass tube is cut by the guide assembly 2 and the cutting machine 3. The gear ring 24 is driven to rotate by the servo motor 21 and the spur gear 22. When the gear ring 24 rotates clockwise, the inclined groove 241 squeezes the first guide post 27, causing the mounting plate 26 to move downward, so that the rotating blade on the cutting machine 3 cuts the glass tube. Subsequently, under the action of the rotating gear ring 24, the mounting plate 26, the cutting machine 3, and the rotating ring 23 are driven to rotate, thereby performing circumferential cutting. After one circumferential cut, the servo motor 21 and the spur gear 22 drive the gear ring 24 to rotate in the opposite direction. At this time, the reverse locking mechanism 25 limits the rotating ring 23 in the reverse direction. Under the guidance of the inclined groove 241, the mounting plate 26 and the cutting machine 3 move upward, and the blade on the cutting machine 3 separates from the cutting surface. At this time, the position of the glass tube is adjusted again by the conveying mechanism 4. The moving ring 43 is driven to move from the front to the back from the inside of the outer shell 1 by the reduction motor 41 and the sector gear 42. When the third guide block 49 enters the area between the second guide block 46 and the first guide block 45, under the guidance of the first guide block 45 near the end of the second guide block 46 and the squeezing of the first baffle 443, the third guide block 49 enters the area between the first guide block 45 and the second baffle 444. At this time, the clamp 48 releases the clamp on the glass tube. Then the third guide block 49 and the clamp 48 reset, waiting for the next conveying.
