Description

Technical Field

[0001] This invention belongs to the technical field of automatic fiber optic wire drawing and turning device, specifically an automatic fiber optic wire drawing and turning device. Background Technology

[0002] In the process of drawing optical fibers, the optical fiber rod needs to be melted and drawn through a drawing tower. In the initial stage of drawing, the optical fiber rod needs to be cut. According to the patent application publication number: CN 108083630 A, a shearing device and method for drawing optical fibers is disclosed. This invention discloses a shearing device for drawing optical fibers, including a traction wheel group, a cylinder, a shearing blade group, a shearing blade group drive motor, a central control unit, and a sensor. The traction wheel group, cylinder, central control unit, and sensor are all fixedly mounted on a base plate. The sensor is located at the top of the shearing device and is used to obtain the diameter of the high-temperature glass falling from the furnace opening of the drawing furnace. The traction unit includes at least a pair of driving wheels and driven wheels. The driving wheels are fixedly mounted on the base plate, and the driven wheels are connected to the cylinder and rotate with the movement of the cylinder, thereby cooperating with the driving wheels to change the diameter of the high-temperature glass. The shearing blade group is located directly below the traction unit and includes a pair of shearing blades. This invention solves the technical problems of existing shearing devices, such as the inability to effectively control the falling speed of high-temperature glass, leading to blockage of the drawing furnace, and the slow movement speed of the shearing blade causing the high-temperature glass above to sway. However, current shearing devices have some problems: 1. When shearing fiber rods, molten glass needs to be sheared. Molten glass has a high temperature, which can easily cause deformation of some components, requiring regular maintenance. During maintenance, components such as cylinders that are bolted on are inconvenient to disassemble, affecting the maintenance progress; 2. During the shearing process, the sheared glass is inconvenient to collect, affecting subsequent processing. Therefore, it is necessary to design an automatic shearing device for fiber drawing and turning. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic fiber optic wire drawing and cutting device to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, this invention provides a technical solution for an automatic fiber optic wire drawing and deflection device:

[0005] An automatic fiber optic drawing and detent cutting device includes a drawing tower base, a frame fixedly connected to the upper end of the drawing tower base, a melting tower fixedly connected to the upper end of the frame, a cylinder contacting the outer side of the frame, an inspection door provided on the frame, a waste bin fixedly connected to the outer side of the frame, a quick-release mechanism provided inside the frame, a receiving mechanism provided inside the waste bin, a collection mechanism provided on the waste bin, a fixed frame fixedly connected to the output end of the cylinder, a fixed blade fixedly connected to the fixed frame, a half gear rotatably connected to the fixed frame, a movable blade fixedly connected to the outer side of the half gear, a full gear mounted on the fixed frame via bearings, and a servo motor fixedly mounted on the fixed frame.

[0006] Preferably, the full gear meshes with the half gear, the output shaft of the servo motor is fixedly connected to the full gear, and a heat insulation cover is fixedly connected to the outside of the mounting bracket to protect the servo motor.

[0007] Preferably, the quick-release mechanism includes a guide frame, a sliding plate, a limiting block, a spring, a connecting column, a connecting rod, and a limiting cover. The guide frame is fixedly connected inside the frame, and the sliding plate is slidably connected to the outside of the guide frame. The sliding plate is slidably connected to the frame, and the limiting block is fixedly connected to the outside of the sliding plate. A spring is provided on the outside of the guide frame, and the connecting column is fixedly connected to the outside of the cylinder. The connecting rod is fixedly connected to the outside of the cylinder, and the limiting cover is fixedly connected inside the frame. The connecting rod is slidably connected to both the frame and the limiting cover. When the access door is opened, the sliding plate is pushed, which moves the limiting block and compresses the spring. When the limiting block disengages from the connecting column, the limiting on the connecting column is released, and the cylinder and other components can then be disassembled, making the device easier to maintain.

[0008] Preferably, one end of the spring is fixedly connected to the guide frame, and the other end of the spring is fixedly connected to the slide plate. The spring can automatically reset the slide plate by its elastic force.

[0009] Preferably, the limiting block is slidably connected to both the frame and the connecting column, and the connecting column is slidably connected to the frame, so that the limiting block can limit the movement of the connecting column.

[0010] Preferably, the receiving mechanism includes an electric telescopic rod, a hinge frame, a hinge seat, a receiving box, a limit strip, a sliding frame, a slider, a tension spring, and a guide plate. The electric telescopic rod is fixedly installed inside the waste bin. A hinge frame is fixedly connected to the output end of the electric telescopic rod. A hinge seat is hinged to the hinge frame. A receiving box is fixedly connected to the hinge seat. A limit strip is fixedly connected to the outer side of the hinge frame. A sliding frame is fixedly connected to the base of the wire drawing tower. A slider is slidably connected to the outer side of the sliding frame. A tension spring is provided on the slider. The electric telescopic rod drives the hinge seat and the receiving box on the hinge frame to move. As the receiving box moves towards the cylinder, the tension spring, which was originally stretched, returns to its original position. The tension spring causes the receiving box to tilt towards the base of the wire drawing tower, and the tension spring pulls the slider to slide along the sliding frame. When the moving blade finishes shearing the bar material, it falls into the receiving box. Then, the electric telescopic rod is controlled to retract. During the retraction process, the electric telescopic rod moves the receiving box towards the waste bin. During the movement, the tension spring moves the slider. When the slider reaches the edge of the sliding frame and can no longer move, the tension spring is stretched. The stretched tension spring generates tension, which causes the receiving box to deflect. After the receiving box deflects at a certain angle, the waste material inside slides downward and slides into the collection bin through the guide plate, thus completing the collection of the bar material.

[0011] Preferably, one end of the tension spring is fixedly connected to the slider, and the other end of the tension spring is fixedly connected to the receiving box. The tension spring can drive the receiving box to deflect by its elastic force.

[0012] Preferably, the collection mechanism includes an internal threaded ring, a collection bucket, a threaded tube, a screw, a top plate, and a guide block. The internal threaded ring is fixedly connected to the waste bin. The collection bucket is installed inside the internal threaded ring via a bearing and is in contact with the waste bin. The threaded tube is installed inside the collection bucket via a bearing, and the screw is threadedly connected inside the threaded tube. One end of the screw is fixedly connected to the top plate, and the guide block is fixedly connected to the outside of the top plate. Both the top plate and the guide block are slidably connected to the collection bucket. By rotating the collection bucket, the collection bucket can be disassembled through the threaded engagement with the internal threaded ring. Then, by rotating the threaded tube, the threaded tube can drive the top plate to move through the threaded engagement with the screw. The top plate can push out the raw material inside, effectively preventing the molten bar stock from sticking to the inside of the collection bucket.

[0013] The beneficial effects of this invention are as follows: This invention relates to an automatic fiber optic drawing and detent cutting device, which is convenient for maintenance and waste collection. In practical use, compared with traditional automatic fiber optic drawing and detent cutting devices, this automatic fiber optic drawing and detent cutting device has the following two beneficial effects:

[0014] First, by adding a quick-release mechanism inside the frame to replace bolts, the cylinder can be easily and quickly released by simply detaching the limit block from the connecting column during disassembly, making the cylinder easier to disassemble, inspect, and maintain.

[0015] Secondly, a waste bin, receiving box, and collection bucket are added to the frame. During the shearing process, the waste can be collected through the receiving box. After the receiving box moves to its original position, the tension of the tension spring can drive the receiving box to deflect, and the waste inside is discharged into the collection bucket through the guide plate, which makes the waste easier to collect.

Detailed Implementation

[0026] like Figure 1-8 As shown, the specific implementation adopts the following technical solution: Example

[0027] An automatic fiber optic drawing and detent cutting device includes a drawing tower base 1, a frame 2 fixedly connected to the upper end of the drawing tower base 1, a melting tower 3 fixedly connected to the upper end of the frame 2, a cylinder 4 contacting the outer side of the frame 2, an inspection door 5 provided on the frame 2, a waste bin 6 fixedly connected to the outer side of the frame 2, a fixed frame 10 fixedly connected to the output end of the cylinder 4, a fixed blade 11 fixedly connected to the fixed frame 10, a half gear 13 rotatably connected to the fixed frame 10, a movable blade 14 fixedly connected to the outer side of the half gear 13, a full gear 15 mounted on the fixed frame 10 via bearings, a servo motor 12 fixedly mounted on the fixed frame 10, the full gear 15 meshing with the half gear 13, the output shaft of the servo motor 12 fixedly connected to the full gear 15, and a heat insulation cover 16 fixedly connected to the outer side of the fixed frame 10 to protect the servo motor 12.

[0028] The frame 2 is internally equipped with a quick-release mechanism 7, which includes a guide frame 71, a sliding plate 72, a limiting block 73, a spring 74, a connecting column 75, a connecting rod 76, and a limiting cover 77. The guide frame 71 is fixedly connected internally to the frame 2, and the sliding plate 72 is slidably connected to the outer side of the guide frame 71. The sliding plate 72 is slidably connected to the frame 2, and the limiting block 73 is fixedly connected to the outer side of the sliding plate 72. A spring 74 is provided on the outer side of the guide frame 71. A connecting column 75 is fixedly connected to the outer side of the cylinder 4, and a connecting rod 76 is fixedly connected to the outer side of the cylinder 4. The limiting cover 77 is fixedly connected internally to the frame 2. The connecting rod 76 is connected to the frame 2 and the limiting cover 77. All cover 77 are slidably connected. Open the inspection door 5, and then push the slide plate 72. The slide plate 72 drives the limit block 73 to move and compresses the spring 74. When the limit block 73 disengages from the connecting column 75, the limitation on the connecting column 75 can be released, and then the cylinder 4 and other components can be disassembled, making the device easier to maintain. One end of the spring 74 is fixedly connected to the guide frame 71, and the other end of the spring 74 is fixedly connected to the slide plate 72. The spring 74 can drive the slide plate 72 to automatically reset through its elastic force. The limit block 73 is slidably connected to both the frame 2 and the connecting column 75. The connecting column 75 is slidably connected to the frame 2, and the limit block 73 can limit the connection column 75.

[0029] The waste bin 6 is internally equipped with a receiving mechanism 8, which includes an electric telescopic rod 81, a hinge frame 82, a hinge seat 83, a receiving box 84, a limiting strip 85, a sliding frame 86, a slider 87, a tension spring 88, and a guide plate 89. The electric telescopic rod 81 is fixedly installed inside the waste bin 6. A hinge frame 82 is fixedly connected to the output end of the electric telescopic rod 81. A hinge seat 83 is hinged to the hinge frame 82, and a receiving plate 89 is fixedly connected to the hinge seat 83. The material box 84 is fixedly connected to the outer side of the hinge frame 82 with a limit strip 85. A sliding frame 86 is fixedly connected to the drawing tower base 1. A slider 87 is slidably connected to the outer side of the sliding frame 86. A tension spring 88 is provided on the slider 87. An electric telescopic rod 81 drives the hinge seat 83 on the hinge frame 82 and the material box 84 to move. As the material box 84 moves towards the cylinder 4, the tension spring 88, which was originally stretched, returns to its original position. The tension spring 88 drives the material box 84 to move closer to the cylinder 4. The base 1 of the wire drawing tower is tilted, and the slider 87 is pulled along the sliding frame 86 by the tension spring 88. When the bar material after the movable blade 14 has completed the shearing falls into the receiving box 84, the electric telescopic rod 81 is controlled to retract. During the retraction process, the electric telescopic rod 81 drives the receiving box 84 to move closer to the waste bin 6. During the movement, the slider 87 is moved by the tension spring 88. When the slider 87 moves to the edge of the sliding frame 86 and cannot move, the tension spring 88 can be stretched. After the tension spring 88 is stretched, it generates tension force, which causes the receiving box 84 to deflect. After the receiving box 84 deflects at a certain angle, the waste material inside slides down and slides into the collection bucket 92 through the guide plate 89, thus completing the collection of the bar material. One end of the tension spring 88 is fixedly connected to the slider 87, and the other end of the tension spring 88 is fixedly connected to the receiving box 84. The tension spring 88 can drive the receiving box 84 to deflect by its elasticity.

[0030] The waste bin 6 is equipped with a collection mechanism 9, which includes an internal threaded ring 91, a collection bucket 92, a threaded tube 93, a screw 94, a top plate 95, and a guide block 96. The internal threaded ring 91 is fixedly connected to the waste bin 6. The collection bucket 92 is mounted inside the internal threaded ring 91 via a bearing and is in contact with the waste bin 6. The threaded tube 93 is mounted inside the collection bucket 92 via a bearing, and the screw 94 is threadedly connected to the inside of the threaded tube 93. One end of the screw 94... A top plate 95 is fixedly connected, and a guide block 96 is fixedly connected to the outer side of the top plate 95. Both the top plate 95 and the guide block 96 are slidably connected to the collection bucket 92. By rotating the collection bucket 92, the collection bucket 92 can be disassembled through the threaded engagement between the collection bucket 92 and the inner threaded ring 91. Then, by rotating the threaded tube 93, the threaded tube 93 can drive the top plate 95 to move through the threaded engagement between the threaded tube 93 and the screw 94. The top plate 95 can push out the raw material inside, which can effectively prevent the molten bar material from sticking to the inside of the collection bucket 92.

[0031] The usage state of this invention is as follows: When in use, the optical fiber preform is inserted into the melting tower 3. After one end of the optical fiber preform melts, the cylinder 4 is started. The cylinder 4 drives the fixed blade 11 and the movable blade 14 on the fixed frame 10 to move. When the fixed blade 11 moves to the lower end of the optical fiber preform, the servo motor 12 is started. The servo motor 12 drives the full gear 15 to rotate. The full gear 15 drives the movable blade 14 to deflect through the half gear 13. During the deflection process, the movable blade 14 can cut the optical fiber preform through the blade engagement process with the fixed blade 11.

[0032] During the shearing process, the electric telescopic rod 81 is activated. The electric telescopic rod 81 drives the hinge seat 83 and the receiving box 84 on the hinge frame 82 to move. As the receiving box 84 moves towards the cylinder 4, the tension spring 88, which was originally stretched, returns to its original position. The tension spring 88 causes the receiving box 84 to tilt towards the wire drawing tower base 1, and pulls the slider 87 along the sliding frame 86. When the bar material after the movable blade 14 has completed shearing falls into the receiving box 84, the electric telescopic rod 81 is then controlled to retract. During the recycling process, the electric telescopic rod 81 drives the receiving box 84 to move closer to the waste bin 6. During the movement, the tension spring 88 drives the slider 87 to move. When the slider 87 moves to the edge of the sliding frame 86 and cannot move, the tension spring 88 can be stretched. After the tension spring 88 is stretched, it generates tension force, which drives the receiving box 84 to deflect. After the receiving box 84 deflects at a certain angle, the waste inside slides down and slides into the collection bin 92 through the guide plate 89, thus completing the collection of the bar material.

[0033] After collecting a certain amount, rotate the collection bucket 92. The collection bucket 92 can be disassembled through the threaded engagement between the collection bucket 92 and the inner threaded ring 91. Then rotate the threaded tube 93. The threaded tube 93 can drive the top plate 95 to move through the threaded engagement between the threaded tube 93 and the screw 94. The top plate 95 can push out the raw material inside, which can effectively prevent the molten bar material from sticking to the inside of the collection bucket 92.

[0034] When it is necessary to inspect the internal components of the device, open the inspection door 5, and then push the slide plate 72. The slide plate 72 drives the limit block 73 to move and compresses the spring 74. When the limit block 73 disengages from the connecting column 75, the limit on the connecting column 75 can be released, and then the cylinder 4 and other components can be disassembled, making the device easier to inspect.
