Description

Technical Field

[0001] The invention relates to the technical field of glass tube production, and in particular to an anti-fracture and processing auxiliary traction device for a glass tube production line. Background Art

[0002] In the field of glass product production, the research and development of energy-saving special equipment is the core path to achieve green manufacturing. In the production process of glass tubes, the horizontal tube drawing process is a common technology, and its traction power is mainly completed by the cold end traction machine. However, some defects such as stone nodules, crystallization, etc. are inevitably produced in the glass production and melting process. These defects will produce large stresses during the cooling process of the glass tube forming part, which can easily cause the glass tube to break in the cooling track, thereby causing production to stop. Once a broken tube occurs, the staff needs to stop the machine for processing and clean up the broken tube glass fragments on the traction machine, which not only increases the work intensity, but also reduces production efficiency. In addition, frequent broken tube processing operations will seriously affect the stability of the manufacturing process, resulting in reduced product quality and increased production costs.

[0003] In the prior art, there are some solutions to the problem of broken tubes in glass tube production lines. For example, the patent with publication number CN218709937U proposes an auxiliary traction device for a glass tube production line, which includes a traction mechanism, a detector and a controller. The traction mechanism clamps the glass tube through a pressure wheel and pulls it to move. The detector is used to detect the movement state of the glass tube, and the controller controls the action of the traction mechanism according to the detection result. Although the device can reduce the downtime after the tube breaks to a certain extent, it still has the following shortcomings: 1. Low efficiency in handling broken pipes: When the existing traction device breaks a pipe, glass fragments are easily stuck in the track or belt gap, which requires manual cleaning, resulting in long downtime and high operating risks in high temperature environments. The processing process is relatively cumbersome and cannot achieve fast and seamless switching, resulting in reduced production efficiency. In addition, if the pipe is not cleaned up after breaking, the broken glass fragments are likely to cause a second pipe break.

[0004] 2. Uneven clamping force: The clamping force of the pressure wheel of the existing device is uneven, which can easily cause uneven force on the glass tube during the traction process, increasing the risk of tube breakage. Summary of the invention

[0005] In order to solve the defects in the prior art, the present invention provides an anti-fracture and processing auxiliary traction device for a glass tube production line, which realizes the synchronous control of the flipping and cleaning of the traction module and the spacing adjustment by using a composite drive flipping system, and the self-cleaning traction of the flexible clamping component and the auxiliary component, so as to realize the function of automatically removing glass debris through mechanical vibration and brushing structure during the traction process; Timely flipping, cleaning, and resetting during pipe breakage greatly improve the efficiency of pipe breakage handling, increase production efficiency and the yield rate of good products, enhance the uniformity and adaptability of the clamping force, avoid the occurrence of secondary pipe breakage caused by broken glass fragments of the pipe, and achieve the purpose of stabilizing the production process and increasing production capacity.

Two groups of first sliding grooves are provided on the inner sides of both ends of the flipping support frame. It is used to transmit torque through double-gear meshing, and at the same time drive the rotation of the flipping support frame and the axial sliding of the traction module. A further improvement lies in that: Both ends of the bearing frame are slidably arranged in the first sliding grooves, and are fixedly connected with first driven tooth blocks.

A cleaning roller brush is also rotatably arranged at the end of the fixed sleeve opposite to the traction wheel. The cleaning roller brush is arranged outside the traction belt. It is used to remove the residual broken glass on the surface of the traction wheel through the spring buffer and the vibration of the vibration bump when the tube breaks, and at the same time, the cleaning roller brush continuously cleans the traction belt. A further improvement lies in that: the surface of the clamping roller is arc-shaped; which is used to increase the contact area with the glass tube, reduce the local pressure, and prevent the surface of the glass tube from being scratched. A further improvement lies in that: the center distance between the first rotating gear and the second rotating gear is equal to the pitch diameter of the drive gear, and the two groups of first sliding grooves are parallelly distributed with the axis of the driven gear as the symmetry axis; which is used to ensure the transmission ratio accuracy and the motion stability of the transmission system, and avoid the vibration caused by gear eccentricity.

[0009] The beneficial effects of the present invention are as follows: 1. The present invention uses a photoelectric sensor to monitor the tube-breaking signal in real time. When tube-breaking occurs, it triggers the composite drive mechanism to realize the synchronous double actions of the 90° flip of the traction module to clean the glass fragments and the distance between the traction modules, avoiding the adhesion or retention of glass fragments on the traction module, which may cause subsequent breakage or damage to the glass tube transportation, being able to automatically clean the glass fragments in time, greatly shortening the tube-breaking processing time to within a few seconds, and at the same time preventing the adhesion or retention of glass fragments on the traction module. By reversing the motor to drive the gear, the flip support frame can be reset within a few seconds to adapt to the high-frequency start and stop of the production line, greatly improving the production efficiency and the qualified product rate of the glass tube, avoiding production delays caused by tube-breaking, and at the same time preventing secondary tube-breaking caused by broken tube glass fragments.

[0010] 2. The present invention realizes three-point flexible clamping through an axial limiting mechanism: a bidirectional threaded screw links the clamping wheel and the arc-shaped clamping roller to form a three-point contact (two wheels + one roller), the clamping force is evenly distributed, the local pressure is even, the radial offset of the glass tube is reduced, and the clamping distance is adjusted by the second drive motor to drive the screw to adapt to different tube diameters, and the adjustment time is short.

[0011] 3. The present invention uses a flexible clamping assembly to make the traction force of the traction belt uniform and realize dynamic adaptability: the traction wheel is buffered by the second spring to absorb radial runout, the traction speed is stable, and the breakage rate of thin-walled tubes is reduced; Efficient self-cleaning is achieved through auxiliary components: the oscillating bump vibrates the traction wheel to remove debris; the cleaning roller brush rotates synchronously with the traction belt to reduce the amount of residual debris, and the maintenance frequency is extended from manual cleaning to all-weather automatic maintenance; the first spring and the second sliding block are combined to offset the impact force caused by the irregular movement of the glass tube, reduce the vibration amplitude of the system, and avoid secondary tube breakage caused by resonance.

[0014] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] According to Figures 1-6 As shown in the figure, an auxiliary traction device for a glass tube 5 production line includes: A load-bearing matrix 1, with an inlet 11 and an outlet 12 respectively provided at both ends thereof. An optoelectronic sensor for detecting whether the glass tube 5 is broken is provided inside the inlet 11. A tipping support frame 2, the two ends of which are rotatably connected to the load-bearing matrix 1 through a composite drive mechanism 3. Two groups of symmetrically arranged traction modules 4, which are slidably arranged along the axial direction of the tipping support frame 2 in its internal guiding cavity. The traction module 4 includes: A load-bearing frame 41 adapted to the shape of the guiding cavity; An axial limiting mechanism 42, arranged at both ends of the load-bearing frame 41; A flexible clamping assembly 43, arranged in the middle of the load-bearing frame 41 and provided with an auxiliary assembly, and the auxiliary assembly is used for self-adaptive tension adjustment and self-cleaning of the flexible clamping assembly 43. The composite drive mechanism 3 is configured to synchronously achieve the circumferential rotation of the tipping support frame 2 and the distance adjustment of the two traction modules 4; An installation cavity is provided inside one end of the load-bearing frame 41. A fifth drive motor is provided in the installation cavity. A driving gear 6 is provided at the output end of the fifth drive motor, and the driving gear 6 meshes with the driven gear 35.

[0016] This device realizes the stable traction of the glass tube 5 through the composite drive mechanism 3 and multi-module collaborative control, which is specifically divided into two modes: normal operation state and broken tube emergency treatment state: The photoelectric sensor inside the feeding port 11 monitors the motion state of the glass tube 5 in real time. When a continuous signal loss is detected, it is determined that the tube is broken. Under normal conditions, the photoelectric sensor continuously outputs a stable signal, and the traction system remains running.

[0017] The composite drive mechanism 3 synchronously realizes the circumferential rotation of the flipping support frame 2 and the axial spacing adjustment of the traction module 4 through a gear drive and a sliding groove structure to adapt to different pipe diameter requirements; the axial limiting mechanism 42 adaptively adjusts the clamping force through the linkage of the bidirectional lead screw 422 and the clamping roller 426 to ensure the axial stability of the glass tube 5; the flexible clamping assembly 43 provides continuous and stable traction force through the combination of the synchronous pulley 431 and the traction belt 432 to reduce surface damage; the fifth drive motor drives the gear 6 to mesh with the driven gear 35 to adjust the spacing of the traction module 4 to adapt to the change in the specification of the glass tube 5.

[0018] After the photoelectric sensor detects a broken tube, the composite drive mechanism 3 is immediately activated: The flipping support frame 2 flips 90°, and at the same time, the spacing of the traction module 4 expands to avoid debris accumulation. The auxiliary component clears the debris on the surface of the traction wheel 445 and the belt through a mechanical vibration and brushing structure. At the same time, the cleaning roller brush 448 continuously cleans the outer side of the traction belt 432. A waste collection box is arranged below the flipping support frame 2 to collect the broken slag of the dropped glass tube 5. After cleaning, the flipping support frame 2 automatically resets and waits for the next glass tube 5 to enter.

[0019] Furthermore, in this embodiment, the composite drive mechanism 3 includes: a first drive motor 31, a drive gear 32, a first rotating gear 33, a second rotating gear 34, a driven gear 35, and a first sliding groove 36; One end of the bearing base 1 is provided with a first drive motor 31. The output shaft of the first drive motor 31 is connected to the drive gear 32. The drive gear 32 meshes with the first rotating gear 33 and the second rotating gear 34 at the same time to form a double-gear transmission pair, where: the first rotating gear 33 is fixedly connected to the outer side of one end of the flipping support frame 2; the second rotating gear 34 passes through and is rotatably connected to the middle of one end of the flipping support frame 2 through a bearing. The second rotating gear 34 is coaxial with the first rotating gear 33 and passes through the axis of the first rotating gear 33 and one end of the flipping support frame 2, and is fixedly connected with a driven gear 35. Two groups of first sliding grooves 36 are arranged on the inner sides of both ends of the flipping support frame 2.

[0020] Both ends of the bearing frame 41 are slidably arranged in the first sliding groove 36 and fixedly connected with a first driven gear block 37. The first driven gear block 37 meshes with the driven gear 35, and its extending direction is the same as that of the first sliding groove 36; The center distance between the first rotating gear 33 and the second rotating gear 34 is equal to the pitch diameter of the driving gear 32, and the two groups of first sliding grooves 36 are parallelly distributed with the axis of the driven gear 35 as the symmetry axis; The composite driving mechanism 3 of this embodiment works as follows: After the first driving motor 31 is started, its output shaft drives the driving gear 32 to rotate. The driving gear 32 meshes with the first rotating gear 33 and the second rotating gear 34 at the same time, forming a double-gear transmission pair. This design distributes the power of a single motor to two execution paths: Path 1: The first rotating gear 33 is fixedly connected with the flipping support frame 2, and its rotation directly drives the entire flipping support frame 2 to rotate circumferentially (such as flipping 90°) around its own axis, that is, the conveying direction of the glass tube 5, so as to disengage from the contact surface of the glass tube 5; Path 2: The second rotating gear 34 is connected with the flipping support frame 2 through a bearing. Its rotational motion is transmitted to the coaxially fixed driven gear 35. The driven gear 35 meshes with the first driven gear block 37, and the first driven gear block 37 is fixed at both ends of the bearing frame 41. When the driven gear 35 rotates with the second rotating gear 34, the first driven gear block 37 linearly slides along the extending direction of the first sliding groove 36 (parallel to the axis of the glass tube 5), thereby driving the two groups of traction modules 4 to move synchronously in opposite directions to achieve pitch adjustment.

[0021] The two groups of first sliding grooves 36 are parallelly distributed with the axis of the driven gear 35 as the symmetry axis, forcing the sliding trajectories of the traction modules 4 to be symmetrical, preventing jamming caused by eccentric loading. By driving a double-gear transmission pair with a single motor, the rotation of the flipping support frame 2 and the sliding adjustment of the traction modules 4 are completed synchronously. During tube breakage handling, while the flipping support frame 2 flips 90° to clean up debris, the pitch of the traction modules 4 automatically expands, exposing the belt gap. The actions of the two are seamlessly connected, reducing downtime. The double-gear coaxial design and the center distance matching the pitch diameter of the driving gear 32 eliminate the cumulative error in the transmission chain, with high transmission accuracy, ensuring no slipping or deviation during the traction process of the glass tube 5.

[0022] In this embodiment, further, the axial limiting mechanism 42 includes: an adjusting housing 421, a bidirectional lead screw 422, a first sliding block, a clamping runner 423, an adjusting gear 424, a second driven gear block 425, a clamping roller 426, and a second driving motor 427; The inner cavity of the adjusting housing 421 is provided with a bidirectional threaded lead screw 422. The two ends of the bidirectional threaded lead screw 422 are respectively helically connected with a first sliding block. The top of the adjusting housing 421 is provided with an opening. The first sliding block passes through the opening and is connected with a clamping runner 423. One end of the bidirectional threaded lead screw 422 passes through and is rotatably connected to one end of the adjusting housing 421 and is connected with an adjusting gear 424. The two ends of the adjusting housing 421 are also slidably provided with second driven tooth blocks 425. One side of the second driven tooth block 425 is meshed with the adjusting gear 424, and the other side is respectively rotatably connected with one end of a clamping roller 426. The output end of the second driving motor 427 is connected to one end of the bidirectional threaded lead screw 422; the surface of the clamping roller 426 is arc-shaped.

[0023] The axial limiting mechanism 42 in this embodiment works as follows: When the second driving motor 427 is started, it drives the bidirectional threaded lead screw 422 to rotate. Since the thread directions at both ends of the bidirectional threaded lead screw 422 are opposite, the two groups of first sliding blocks move symmetrically and reversely along the bidirectional threaded lead screw 422, driving the clamping runner 423 to approach or move away synchronously. When the bidirectional threaded lead screw 422 rotates, the adjusting gear 424 fixed at one of its ends rotates synchronously. The adjusting gear 424 meshes with the second driven tooth blocks 425 on both sides, pushing the second driven tooth blocks 425 to slide along the slide rails of the adjusting housing 421. The second driven tooth blocks 425 drive the clamping rollers 426 to move up and down, forming a three-point clamping structure with the clamping runner 423. The clamping runner 423 directly contacts the surface of the glass tube 5. The clamping distance is adjusted by the movement of the first sliding block. The arc-shaped surface of the clamping roller 426 fits the outer wall of the glass tube 5, providing auxiliary clamping force and forming a stable support. By adjusting the forward and reverse rotation of the motor, the clamping distance can be dynamically adjusted to adapt to glass tubes 5 with different diameters.

[0024] In a further aspect of this embodiment, the flexible clamping assembly 43 includes: a synchronous pulley 431, a traction belt 432, and a third driving motor 433; Two groups of synchronous pulleys 431 are symmetrically arranged in the middle of the carrying frame 41. A traction belt 432 is arranged outside the two groups of synchronous pulleys 431. The output end of the third driving motor 433 is connected to any one of the synchronous pulleys 431 through a speed reducer.

[0025] The auxiliary assembly includes: a vibration frame 441, a second sliding block 442, a first spring 443, a fixed sleeve 444, a traction wheel 445, a fourth driving motor 446, a vibration bump 447, a cleaning roller brush 448, and a second spring 449; The oscillation frame 441 is arranged between two groups of traction wheels 445. Second sliding blocks 442 are slidably arranged on the inner sides of both ends of the oscillation frame 441. First springs 443 are respectively arranged at the upper and lower ends of the second sliding blocks 442. One end of each first spring 443 is connected to the oscillation frame 441, and the other end is connected to the second sliding block 442. A fixing sleeve 444 is connected between the two groups of second sliding blocks 442. Several groups of traction wheels 445 are slidably arranged on one end of the fixing sleeve 444 close to the glass tube 5. A second spring 449 is sleeved outside each traction wheel 445. One end of the second spring 449 is connected to the traction wheel 445, and the other end is connected to the fixing sleeve 444. A fourth driving motor 446 is slidably arranged on one end of the fixing sleeve 444 close to the glass tube 5. An oscillation bump 447 is arranged at the output end of the fourth driving motor 446. A cleaning roller brush 448 is rotatably arranged at the end of the fixing sleeve 444 opposite to the traction wheels 445. The cleaning roller brush 448 is arranged outside the traction belt 432.

[0026] The flexible clamping assembly 43 and the auxiliary assembly in this embodiment work as follows: After the third driving motor 433 is started, the speed is reduced and the torque is increased through the reducer, driving the rotation of the synchronous pulley 431 on either side. The two groups of synchronous pulleys 431 form a closed-loop drive through the traction belt 432, and the belt runs along the conveying direction of the glass tube 5 at a constant linear speed.

[0027] The traction belt 432 is made of rubber material with a high coefficient of friction, and anti-slip patterns are provided on its surface, forming a flexible contact with the surface of the glass tube 5 to avoid scratches caused by hard friction. When the diameter of the glass tube 5 fluctuates or the surface is uneven, the traction belt 432 adaptively fits through elastic deformation to keep the contact pressure uniform.

[0028] After the photoelectric sensor detects a broken tube, the composite drive mechanism 3 is started, the flipping support frame 2 is flipped by 90°, and at the same time, the distance between the traction modules 4 is enlarged. At this time, the fourth driving motor 446 is started to drive the oscillation bump 447 to rotate. The eccentric structure of the bump causes the fixing sleeve 444 to generate periodic vibrations. The second sliding block 442 slides along the oscillation frame 441, and in cooperation with the expansion and contraction of the first spring 443, the vibrations are transmitted to the traction wheels 445 through the second spring 449. The traction wheels 445 shake off the glass debris adhered to the surface of the traction belt 432 under the vibration. The cleaning roller brush 448 is driven to rotate by the friction of the traction belt 432 (the rotation speed is synchronized with the linear speed of the belt), and its bristles are made of high-temperature resistant nylon material, continuously scraping the surface of the traction belt 432 to remove the residual debris and molten glass slag.

[0029] When there is radial runout in the glass tube 5, the traction wheel 445 is extruded by an external force and compresses and rebounds through the second spring 449 to absorb vibration energy and prevent the impact from being transmitted to the glass tube 5. The second slider 442 slides along the shock frame 441 and cooperates with the expansion and contraction of the first spring 443 to allow the overall slight displacement of the fixing sleeve 444, further balancing the irregular movement of the glass tube 5.

[0030] The flexible contact design of the traction belt 432 adapts to glass tubes 5 with different diameters, and the surface pressure is evenly distributed to avoid invisible damage caused by local stress concentration. The shock bump 447 is linked with the cleaning roller brush 448 to achieve the real-time cleaning of the traction wheel 445 and the traction belt 432, ensuring the removal of debris residues, and extending the cleaning cycle from manual cleaning to 24-hour automatic maintenance.

[0031] In the scenario of tube breakage, the glass fragments stuck in the gaps of the traction belt 432 can be removed in a very short time through high-frequency vibration. The radial runout of the glass tube 5 can be absorbed by the second spring 449 and the first spring 443, and the traction speed fluctuation is controlled within ±1%, ensuring the forming accuracy of the thin-walled glass tube 5 with a wall thickness ≤1 mm. When the traction is at high speed, the vibration amplitude of the system decreases, avoiding the risk of tube breakage caused by resonance.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
