Description

Technical Field

[0001] The present invention belongs to the technical field of high-end equipment manufacturing, and specifically relates to a grinding machine for processing glass fiber filaments. Background Art

[0002] Glass fiber filaments are slender fibers made of glass, mainly produced by methods such as rotating or stretching molten glass. They have good tensile strength, high temperature resistance, and electrical insulation properties. Glass fiber filaments are widely used in various fields, such as building materials, aerospace, automotive manufacturing, electronic equipment, etc. However, in order to meet specific engineering requirements, glass fiber filaments cannot be directly used after production because their surfaces are not completely smooth. Therefore, a grinding machine is needed to grind the surface of the glass fiber filaments. The grinding machine can effectively reduce the surface roughness of the glass fiber filaments and make the surface of the glass fiber filaments more flat and uniform. In the prior art, for example, a Chinese invention patent with the patent number 2024100451086 discloses a grinding machine for processing glass fiber filaments, which grinds the glass fiber filaments passing vertically through its axis by grinding rollers distributed vertically. However, in the actual operation process, since the glass fiber filaments are perpendicular to the outer surface of the grinding rollers, in order to ensure that the entire surface of the glass fiber filaments is ground, the glass fiber filaments need to be twisted. However, this design makes the grinding process complicated and uncontrollable. Each part of the surface of the glass fiber filaments cannot be effectively and evenly ground, which may affect the grinding effect, and the perpendicular design reduces the utilization rate of the surface of the grinding rollers, reducing the practicality of the entire device. Therefore, it is urgent to solve this problem. Summary of the Invention

[0003] The purpose of the present invention is to provide a grinding machine for processing glass fiber filaments to solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention provides the following technical solution: A grinding machine for processing glass fiber filaments, comprising a bracket, a cylinder body, glass fiber filaments, a wire pay-off roller and a wire take-up roller. Inside the cylinder body, front and rear groups of support cylinders are rotatably installed. Inside the support cylinders, a planetary carrier is fixedly connected. Between the two planetary carriers, a first support shaft, a second support shaft, a first rotating shaft and a second rotating shaft are rotatably installed. On the outer surface of the first support shaft, a first grinding roller is installed. On the outer surface of the second support shaft, a second grinding roller is installed. At both ends of the first support shaft and the second support shaft, transmission gears are fixedly installed. The first rotating shaft and the second rotating shaft are each provided with two groups distributed circumferentially up and down. At both ends of the first rotating shaft, first planetary gears are installed. At both ends of the second rotating shaft, second planetary gears are installed. The first planetary gears and the second planetary gears are meshed with each other. On the front and rear sides of the inner wall of the cylinder body, external gear rings are fixedly installed. The second planetary gears are meshed with the inner walls of the external gear rings. On the outer surface of the front support cylinder, a driven gear is installed. On the top of the cylinder body, a motor is installed. On the output shaft of the motor, a driving gear is installed. The driving gear is meshed with the driven gear. At the bottom of the cylinder body, a blanking groove is opened. The second planetary gears are thicker than the first planetary gears, and the first planetary gears and the external gear rings are distributed in a staggered manner along the axis of the cylinder body.

[0005] As a preferred solution of the present invention, the wire pay-off roller and the wire take-up roller are distributed one in front of the other on the front and rear sides of the cylinder body. The glass fiber filaments are wound around the outer surfaces of the wire pay-off roller and the wire take-up roller. The first grinding roller and the second grinding roller are symmetrically distributed left and right. The glass fiber filaments are located between the first grinding roller and the second grinding roller.

[0006] As a preferred solution of the present invention, the upper first planetary gear is meshed with the left transmission gear, and the upper second planetary gear is meshed with the right transmission gear.

[0007] As a preferred solution of the present invention, the rotation direction of the first grinding roller is opposite to that of the second grinding roller, and the rotation speeds of the first grinding roller and the second grinding roller are the same. The outer surfaces of the glass fiber filaments are respectively in contact with the outer surfaces of the first grinding roller and the second grinding roller.

[0008] As a preferred solution of the present invention, in the middle of the outer side of the planetary carrier, a material passing cylinder is fixedly installed. The glass fiber filaments pass through the material passing cylinder and the planetary carrier.

[0009] As a preferred solution of the present invention, the planetary carrier drives the first rotating shaft, the second rotating shaft, the first support shaft and the second support shaft to revolve and rotate simultaneously through the external gear ring, the second planetary gear, the first planetary gear and the transmission gear.

[0010] As a preferred solution of the present invention, the opening of the material passing cylinder is in the shape of a flared trumpet, so that the glass fiber filaments can easily pass through the planetary carrier and enter the inside of the cylinder body.

[0011] As a preferred embodiment of the present invention, four sets of the brackets are provided and are respectively welded to the front and rear sides of the bottom of the cylinder body. The first planet gears and the second planet gears on the upper side and the first planet gears and the second planet gears on the lower side are symmetrically distributed about the center along the inner wall of the motor.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present device changes the contact mode between the glass fiber filaments and the first grinding roller and the second grinding roller, and makes full use of the form of the revolution plus rotation of the first grinding roller and the second grinding roller to comprehensively cover the outer surface of the glass fiber filaments, thereby effectively improving the grinding efficiency of the device. By providing a planet carrier, a support cylinder, a first rotating shaft and a second rotating shaft rotatably installed on the inner wall of the cylinder body, the first grinding roller and the second grinding roller are symmetrically distributed on both sides of the glass fiber filaments. The outer surfaces of the first grinding roller and the second grinding roller are in contact with the glass fiber filaments, and the axes of the first grinding roller, the second grinding roller and the glass fiber filaments are parallel. Then, by the first planet gear and the second planet gear which are meshed with each other and rotatably installed on the surface of the planet carrier, the second planet gear is meshed with the external gear ring, and the first planet gear and the external gear ring are staggeredly distributed. When the planet carrier drives the structures on the entire planet carrier to rotate under the drive of the motor, the second planet gear rotates around its own axis while revolving, and transmits the power to the second grinding roller and the first grinding roller respectively through the transmission gears, so that the first grinding roller and the second grinding roller can move at the same rotational speed and in opposite directions, thereby grinding the outer surface of the glass fiber filaments. At the same time, since the second grinding roller and the first grinding roller also revolve, the second grinding roller and the first grinding roller can comprehensively cover the outer surface of the glass fiber filaments through revolution, so that the grinding of the glass fiber filaments is more uniform.

[0014] 2. The power of the second planet gear of the present device comes from the revolution of the planet carrier driving it and meshing with the external gear ring to rotate around its own axis, and this power is respectively output to the first grinding roller and the second grinding roller. The second planet gear is directly meshed with the transmission gear on the right side and transmits the power to the second grinding roller. In addition, the second planet gear transmits the power to the first grinding roller along the first planet gear and the transmission gear on the left side, so that the first grinding roller and the second grinding roller have the same rotational speed and opposite directions. When the glass fiber filaments enter between the first grinding roller and the second grinding roller and are tightened, the frictional forces generated by the first grinding roller and the second grinding roller rotating in opposite directions on the glass fiber filaments are just opposite and of equal magnitude, so that the resultant frictional torque of the first grinding roller and the second grinding roller on the whole glass fiber filaments is zero, and the state of the glass fiber filaments located between the first grinding roller and the second grinding roller can be effectively and stably maintained, preventing the glass fiber filaments from rotating and shifting as the first grinding roller and the second grinding roller rotate around their own axes.

[0015] 3. Finally, the rotating directions of the first grinding roller and the second grinding roller are opposite, so that the friction forces acting on the glass fiber filaments are opposite, and thus they just cancel each other out during the rotation of the first grinding roller and the second grinding roller. The first grinding roller and the second grinding roller designed in this device are parallel to the glass fiber filaments, directly avoiding the defects such as small contact area and uneven force and easy damage caused by the perpendicular axes of the workpiece and the grinding piece in the prior art. The overall force on the glass fiber filaments is uniform, and it will not be damaged possibly due to the small pressure area during the movement, effectively protecting the glass fiber filaments.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 8 shown, an embodiment of the present invention provides a grinding machine for processing glass fiber filaments, which includes a bracket 1, a cylinder body 2, glass fiber filaments 13, a wire pay-off roller 14 and a wire take-up roller 15. Two sets of front and rear support cylinders 5 are rotatably installed inside the cylinder body 2. A planet carrier 6 is fixedly connected to the inner side of the support cylinder 5. A support shaft one 11, a support shaft two 17, a rotating shaft one 9 and a rotating shaft two 10 are rotatably installed between the two planet carriers 6. A grinding roller one 12 is installed on the outer surface of the support shaft one 11, and a grinding roller two 18 is installed on the outer surface of the support shaft two 17. Transmission gears 19 are fixedly installed at both ends of the support shaft one 11 and the support shaft two 17. The rotating shaft one 9 and the rotating shaft two 10 are both arranged in two sets distributed circumferentially up and down. Planet gears one 20 are installed at both ends of the rotating shaft one 9, and planet gears two 21 are installed at both ends of the rotating shaft two 10. The planet gears one 20 and the planet gears two 21 are meshed with each other. Outer gear rings 22 are fixedly installed on the front and rear sides of the inner wall of the cylinder body 2. The planet gears two 21 are meshed with the inner walls of the outer gear rings 22. A driven gear 8 is installed on the outer surface of the front support cylinder 5. A motor 3 is installed on the top of the cylinder body 2. A driving gear 4 is installed on the output shaft of the motor 3. The driving gear 4 is meshed with the driven gear 8. A blanking groove 16 is opened at the bottom of the cylinder body 2. The planet gears two 21 are thicker than the planet gears one 20, and the planet gears one 20 and the outer gear rings 22 are arranged in a staggered manner along the axis of the cylinder body 2;

[0027] The device changes the contact mode between the glass fiber filament 13 and the first grinding roller 12 and the second grinding roller 18, and makes full use of the form of the revolution plus rotation of the first grinding roller 12 and the second grinding roller 18 to comprehensively cover the outer surface of the glass fiber filament 13, thereby effectively improving the grinding efficiency of the device. By arranging the planet carrier 6, the support cylinder 5, the first rotating shaft 9 and the second rotating shaft 10 rotatably installed on the inner wall of the cylinder body 2, the first grinding roller 12 and the second grinding roller 18 are symmetrically distributed on both sides of the glass fiber filament 13. The outer surfaces of the first grinding roller 12 and the second grinding roller 18 are in contact with the glass fiber filament 13, and the axes of the first grinding roller 12, the second grinding roller 18 and the glass fiber filament 13 are parallel. Then, by the mutually meshing first planet gear 20 and second planet gear 21 rotatably installed on the surface of the planet carrier 6, the second planet gear 21 is meshed with the external gear ring 22, and the first planet gear 20 and the external gear ring 22 are staggeredly distributed. When the planet carrier 6 drives the structures on the entire planet carrier 6 to rotate under the drive of the motor 3, the second planet gear 21 rotates while revolving, and transmits the power to the second grinding roller 18 and the first grinding roller 12 respectively through the transmission gear 19, so that the first grinding roller 12 and the second grinding roller 18 can move at the same speed and in opposite directions, thereby performing grinding operation on the outer surface of the glass fiber filament 13. At the same time, since the second grinding roller 18 and the first grinding roller 12 also revolve, the second grinding roller 18 and the first grinding roller 12 can comprehensively cover the outer surface of the glass fiber filament 13 through revolution, so that the grinding of the glass fiber filament 13 is more uniform.

[0028] Among them, the wire feeding roller 14 and the wire winding roller 15 are distributed one in front of the other on the front and rear sides of the cylinder body 2. The glass fiber filament 13 is wound around the outer surfaces of the wire feeding roller 14 and the wire winding roller 15. The first grinding roller 12 and the second grinding roller 18 are symmetrically distributed left and right, and the glass fiber filament 13 is located between the first grinding roller 12 and the second grinding roller 18;

[0029] The glass fiber filament 13 is fed by the wire feeding roller 14 and wound by the wire winding roller 15. The symmetrically distributed first grinding roller 12 and second grinding roller 18 just clamp the glass fiber filament 13 entering the inner cavity of the cylinder body 2 in the middle and perform grinding operation synchronously.

[0030] Among them, the upper first planet gear 20 is meshed with the left transmission gear 19, and the upper second planet gear 21 is meshed with the right transmission gear 19;

[0031] Such as Figure 5As shown, the power of the second planetary gear 21 of the device is driven by the planet carrier 6 to revolve and meshes with the external gear ring 22 to rotate. This power is respectively output to the first grinding roller 12 and the second grinding roller 18. The second planetary gear 21 directly meshes with the transmission gear 19 on the right and transmits the power to the second grinding roller 18. In addition, the second planetary gear 21 transmits the power along the first planetary gear 20 and the transmission gear 19 on the left to the first grinding roller 12. This makes the rotational speeds of the first grinding roller 12 and the second grinding roller 18 the same and the rotation directions opposite. When the glass fiber filament 13 enters between the first grinding roller 12 and the second grinding roller 18 and is tightened, the frictional forces generated by the first grinding roller 12 and the second grinding roller 18 with opposite rotation directions on the glass fiber filament 13 are just opposite and of comparable magnitude. This makes the resultant frictional torque of the first grinding roller 12 and the second grinding roller 18 on the glass fiber filament 13 zero, and can effectively and stably maintain the state of the glass fiber filament 13 between the first grinding roller 12 and the second grinding roller 18, preventing the glass fiber filament 13 from rotating and shifting as the first grinding roller 12 and the second grinding roller 18 rotate.

[0032] Among them, the rotation direction of the first grinding roller 12 is opposite to that of the second grinding roller 18, the rotational speeds of the first grinding roller 12 and the second grinding roller 18 are the same, and the outer surfaces of the glass fiber filament 13 are respectively in contact with the outer surfaces of the first grinding roller 12 and the second grinding roller 18;

[0033] The rotation directions of the first grinding roller 12 and the second grinding roller 18 are opposite, so that the directions of the frictional forces on the glass fiber filament 13 are opposite, and thus just cancel each other out during the rotation of the first grinding roller 12 and the second grinding roller 18. The first grinding roller 12 and the second grinding roller 18 designed in this device are parallel to the glass fiber filament 13, directly avoiding the defects such as small contact area and uneven force and easy damage caused by the perpendicular axes of the workpiece and the grinding part in the prior art. The overall force on the glass fiber filament 13 is uniform, and it will not be damaged possibly due to the small pressure area during the movement process, effectively protecting the glass fiber filament 13.

[0034] Among them, a material passing cylinder 7 is fixedly installed in the middle of the outer side of the planet carrier 6, and the glass fiber filament 13 passes through the material passing cylinder 7 and the planet carrier 6;

[0035] The material passing cylinder 7 is responsible for guiding the glass fiber filament 13 to enter the inside of the cylinder body 2. Its opening is communicated with the middle opening of the planet carrier 6, so as to facilitate the glass fiber filament 13 to enter and exit the inside of the cylinder body 2.

[0036] Among them, the planet carrier 6 drives the first rotating shaft 9, the second rotating shaft 10, the first support shaft 11, and the second support shaft 17 to revolve and rotate simultaneously through the external gear ring 22, the second planetary gear 21, the first planetary gear 20, and the transmission gear 19;

[0037] The first rotating shaft 9, the second rotating shaft 10, the first support shaft 11 and the second support shaft 17 rotatably installed between the two planet carriers 6 obtain the self-rotation power through the second planet gear 21, the first planet gear 20 and the transmission gear 19. When the planet carrier 6 drives the second planet gear 21 to rotate, since the second planet gear 21 meshes with the outer gear ring 22, the second planet gear 21 begins to rotate, and at the same time, transmits the rotation power to the first grinding roller 12 and the second grinding roller 18.

[0038] Among them, the opening of the material passing cylinder 7 is in an open trumpet shape, so that the glass fiber filaments 13 can easily pass through the planet carrier 6 and enter the interior of the cylinder body 2;

[0039] The material passing cylinder 7 with an open trumpet shape can facilitate the entry of the glass fiber filaments 13 into it and enter the interior of the cylinder body 2.

[0040] Among them, the brackets 1 are set in four groups and are respectively welded to the front and rear sides of the bottom of the cylinder body 2. The upper first planet gear 20 and the second planet gear 21 and the lower first planet gear 20 and the second planet gear 21 are symmetrically distributed along the inner wall of the motor 3;

[0041] The first planet gear 20 and the second planet gear 21 are divided into two groups distributed circumferentially up and down, and are symmetrically distributed with the axis of the motor 3 as the reference, maintaining the continuity of the power transmission between the second planet gear 21 and the first grinding roller 12 and the second grinding roller 18.

[0042] Working principle:

[0043] When this device is working: First, the wire releasing roller 14 releases the glass fiber filaments 13, so that the glass fiber filaments 13 enter from the front of the device and are pulled out from the rear of the device, and are wound around the outer surface of the wire winding roller 15. Then, the motor 3 is started, and drives the driving gear 4, the driven gear 8, the support cylinder 5 and the planet carrier 6 to rotate. At this time, the planet carrier 6 drives the first rotating shaft 9, the second rotating shaft 10, the first support shaft 11, the first grinding roller 12, the second support shaft 17 and the second grinding roller 18 to revolve around the axis of the motor 3. At the same time, since the second planet gear 21 is driven to work, it generates self-rotation power through meshing with the outer gear ring 22, and transmits the power to the second support shaft 17 and the second grinding roller 18 directly through a set of transmission gears 19 on the one hand, and transmits the power to the first support shaft 11 and the first grinding roller 12 through another set of transmission gears 19 on the other hand. At this time, the first grinding roller 12 and the second grinding roller 18 rotate and work synchronously, and their rotation directions are opposite and the rotation speeds are the same. The first grinding roller 12 and the second grinding roller 18 respectively grind the two relatively symmetrical sides of the outer surface of the glass fiber filaments 13. At the same time, after revolution, the first grinding roller 12 and the second grinding roller 18 can also cover the entire surface of the glass fiber filaments 13;

[0044] Then, since the rotation directions of the first grinding roller 12 and the second grinding roller 18 are opposite and their rotational speeds are the same, the frictional forces generated by the two on the outer surface of the glass fiber filament 13 exactly cancel each other out on the glass fiber filament 13, preventing the glass fiber filament 13 from rotating and shifting with the self-rotation of the first grinding roller 12 and the second grinding roller 18. At this time, the take-up roller 15 is synchronously started and pulls the glass fiber filament 13 backward to achieve winding, and the pay-off roller 14 releases the glass fiber filament 13 to realize the continuous grinding function of the device. The fixed impurities generated by grinding can be discharged downward along the material discharge chute 16.
