Description

Technical Field

[0001] The invention relates to the technical field of glass wool manufacturing, in particular to a centrifugal system for molten glass. Background Art

[0002] Centrifugal glass wool is a filamentary material made by fiberizing molten glass using a centrifugal blowing process and spraying thermosetting resin on it. It is then subjected to deep processing by heat curing to be made into a series of products with multiple uses.

[0003] At present, a Chinese patent with publication number CN103910486A and publication date July 9, 2014 discloses a glass fiber fiberizing machine, including: a main shaft, a main body, an inner water jacket, an outer water jacket, a belt, a motor, a centrifugal disk, an inner burner, a cotton cutter, a main burner, and a connecting short shaft. The outer diameter of the centrifugal disk is 420 to 550 mm.

[0004] After the molten glass enters the centrifugal disk, it will be centrifuged and discharged downward in the form of glass fibers. The principle is similar to the production process of cotton candy.

[0005] At present, a Chinese patent with publication number CN111099830A and publication date May 5, 2020 discloses an environmentally friendly glass wool and a preparation method thereof, wherein a preparation method of environmentally friendly glass wool specifically includes the following steps: S1. Put broken glass, soda ash, dolomite, nano-alumina, calcium oxide, and magnesium silicate into an industrial kiln for melting for manufacturing glass wool. The melting temperature is between 1500° and 1750°. After 30 to 45 minutes, the glass liquid can be melted to obtain glass liquid for producing glass wool; S2. Put the glass liquid into a glass wool centrifuge for centrifugal blowing to obtain glass fiber, and evenly spray the adhesive onto the surface of the glass fiber; S3. Collect the glass fiber through a cotton collector and then transport it to a curing furnace for curing to obtain glass wool.

[0006] In step S2, the molten glass liquid is put into a glass wool centrifuge (i.e., a fiber forming machine) for centrifugal blowing to obtain glass fibers, and an adhesive is evenly sprayed onto the surface of the glass fibers, wherein the adhesive is mostly resin glue, and the resin glue allows the glass fibers to be randomly bonded together when falling, and the bonded glass fibers can fall on a cotton collecting conveyor belt after falling. After the cotton collecting conveyor belt passes through multiple centrifuges, the glass fibers can be stacked together on the cotton collecting conveyor belt, thereby gathering into fluffy and soft glass wool, and finally sent to a curing furnace for curing.

[0007] When the bonded glass fibers fall onto the cotton collecting conveyor belt, since the centrifuge is often installed directly above the cotton collecting conveyor belt, the width of the glass wool laid on the cotton collecting conveyor belt is fixed. This will result in the glass wool being unable to be laid on the cotton collecting conveyor belt to a corresponding width when wider glass wool needs to be processed. Summary of the invention

[0008] The object of the present invention is to provide a centrifugal system for molten glass, which can facilitate the swing laying of glass fibers on a cotton collecting conveyor belt, so that glass fibers can lay glass wool of different widths on the cotton collecting conveyor belt.

[0009] The above technical purpose of the present invention is achieved through the following technical scheme: a centrifugal system for molten glass, including a bracket, a centrifuge located on the upper side of the bracket, a spraying assembly arranged on the bracket located on the lower side of the centrifuge and used for spraying resin glue, and a cotton collecting conveyor belt located below the spraying assembly. A guide cylinder for the bonded glass fiber to fall into is arranged between the cotton collecting conveyor belt and the spraying assembly. The guide cylinder includes a first cylinder body that is funnel-shaped with a larger upper part and a smaller lower part and the upper end of which is rotatably connected to the bracket, and a second cylinder body that is arranged at the lower end of the first cylinder body and has a rectangular cross-section. A driving assembly for driving the second cylinder body to swing left and right at different angles is arranged on the bracket.

[0010] By adopting the above technical scheme, after the glass fiber is discharged from the lower side of the centrifuge, it first passes through the spraying assembly, and the resin glue is sprayed on the falling glass fiber by the spraying assembly, and then the glass fibers bonded together can fall into the guide cylinder, wherein the guide cylinder includes a first cylinder body that is larger than the upper part and smaller than the lower part, and a second cylinder body that is arranged at the lower end of the first cylinder body and has a rectangular cross-section, the first cylinder body can guide the falling glass fiber, so that the glass fiber is gathered in the second cylinder body and falls, and at the same time, since the upper end of the first cylinder body is rotatably connected to the bracket, the driving assembly on the bracket is used to drive the second cylinder body to swing left and right, and the glass fiber falling from the second cylinder body can be swung left and right and laid on the cotton collecting conveyor belt, thereby realizing the swinging laying of the glass fiber on the cotton collecting conveyor belt, wherein after the driving assembly is used to drive the second cylinder body to swing left and right at different angles, the glass fiber can lay glass wool of different widths on the cotton collecting conveyor belt.

[0011] A further setting of the present invention is that: the driving assembly includes a cross frame arranged on the bracket, guide sleeves arranged at the left and right ends of the cross frame, a connecting plate located between the two side guide sleeves and extending in the vertical direction, a long strip hole opened on the connecting plate and extending in the vertical direction, connecting arms arranged on both sides of the connecting plate and passing through the guide sleeves, a rectangular frame arranged between the two side connecting arms and for the second cylinder to pass through, a driving motor arranged on the back of the middle part of the cross frame, a rotating arm with one end connected to the output shaft of the driving motor, and a convex shaft arranged at the end of the rotating arm away from the driving motor and embedded in the long strip hole. The connecting arm is in a "U" shape with one end connected to the connecting plate and the other end connected to the rectangular frame. The width inside the rectangular frame is greater than the width of the cross section of the second cylinder.

[0012] By adopting the above technical solution, after the driving motor drives the rotating arm to rotate, since the convex shaft at the end of the rotating arm away from the driving motor is embedded in the long strip hole of the connecting plate, and since one end of the connecting arm is connected to the connecting plate and the other end is connected to the rectangular frame, and at the same time the connecting arm passes through the guide sleeve, the circular motion of the convex shaft can drive the connecting arm and the rectangular frame to move left and right back and forth. Among them, the rectangular frame is used for the second cylinder to pass through, and the width inside the rectangular frame is greater than the width of the cross section of the second cylinder. The rectangular frame moving left and right can drive the second cylinder to swing left and right, realizing the swinging laying of glass fibers on the cotton collecting conveyor belt.

[0013] A further setting of the present invention is that: a long strip opening is opened in the rotating arm, and the extending direction of the long strip opening is parallel to the extending direction of the rotating arm. A threaded shaft with both ends rotatably connected to the inner walls at both ends of the long strip opening is arranged in the long strip opening. An adjusting motor with an output shaft connected to the end of the threaded shaft is arranged at the end of the rotating arm away from the driving motor. A slider embedded in the long strip opening is arranged at the end of the convex shaft. A threaded hole for the threaded shaft to be threadedly connected is opened on the slider.

[0014] By adopting the above technical solution, when it is necessary to adjust the swinging angle of the second cylinder left and right, the adjusting motor is used to drive the threaded shaft to rotate. Since the slider at the end of the convex shaft is embedded in the long strip opening, and the threaded hole on the slider is for the threaded shaft to be threadedly connected, the forward and reverse rotation of the threaded shaft can drive the slider and the convex shaft to move back and forth along the long strip opening, thereby adjusting the diameter of the circular motion of the convex shaft. Subsequently, by changing the diameter of the circular motion of the convex shaft, the left and right translation distance of the rectangular frame can be changed, and finally the swinging angle of the second cylinder left and right can be adjusted.

[0015] The present invention is further configured as follows: a knocking assembly for knocking the upper outer wall of the first cylinder is also provided on the cross frame, and the knocking assembly includes a column arranged at one end of the cross frame and extending in a vertical upward direction, a rotating shaft with one end rotatably connected to the upper end of the column and the other end extending to the outer wall of the first cylinder, a connecting spring arranged at an end of the rotating shaft away from the column, a knocking ball arranged at an end of the connecting spring away from the rotating shaft, a fixed arm whose upper end is connected to an end of the rotating shaft close to the column and extending in a vertical downward direction, a return spring with one end connected to the lower end of the fixed arm and the other end connected to the cross frame, a first connecting rod integrally arranged at the lower end of the fixed arm, a second connecting rod arranged at an end of the first connecting rod away from the fixed arm, and a third connecting rod with one end connected to the output shaft of the driving motor and the other end used to abut against the second connecting rod.

[0016] By adopting the above technical scheme, when the glass fiber falls on the inner wall of the first cylinder, since the first cylinder is in the shape of a funnel with a larger top and a smaller bottom, the glass fiber falling in the first cylinder will first hit the inner wall of the upper part of the first cylinder, and then slide down along the inclined inner wall of the first cylinder. At this time, since the glass fiber has resin glue, the glass fiber that first falls on the upper part of the first cylinder will adhere to the inner wall of the upper part of the first cylinder; at this time, by using the knocking assembly also provided on the horizontal frame, when the circular motion of the convex shaft drives the second cylinder to swing to the left, the third connecting rod will swing upward with the rotation of the output shaft of the driving motor, and then the third connecting rod can hit the second connecting rod and drive the second connecting rod to swing upward, and at this time the second connecting rod can drive the rotating shaft to rotate and drive the fixed arm to swing, and the reset spring is stretched at the same time;

[0017] As the convex shaft continues to drive the second cylinder to swing to the left, when the second cylinder swings to the left to the extreme position, the upper part of the first cylinder is close to the initial position of the knocking ball. At this time, the third connecting rod is just separated from the second connecting rod. As the reset spring is reset, the reset spring can drive the rotating shaft to rotate in the opposite direction and drive the fixed arm to swing in the opposite direction. Then the knocking ball at the end of the rotating shaft can bounce back to the initial position. At this time, the knocking ball can hit the inclined upper outer wall of the first cylinder. The glass fiber attached to the upper inner wall of the first cylinder can be vibrated off through the vibration action of the knocking ball, which can finally help the glass fiber to fall efficiently from the guide cylinder.

[0018] The present invention is further configured as follows: the striking ball is made of rubber material.

[0019] By adopting the above technical solution, the rubber knocking ball can reduce the noise pollution caused by knocking.

[0020] The present invention is further configured as follows: a fixed shaft is arranged on the outer wall of the upper end of the first cylinder, a fixed plate is arranged on the bracket, and a bearing seat for rotationally connecting the fixed shaft is arranged on the fixed plate.

[0021] By adopting the above technical solution, the first cylinder is rotatably connected to the bearing seat on the fixed plate by using the end of the fixed shaft, so that the upper end of the first cylinder is rotatably connected to the bracket.

[0022] The present invention is further configured as follows: the spray assembly includes a first spray ring located below the centrifuge discharge port, a glue injection pump arranged on a bracket and connected to the first spray ring through a hose, a fourth connecting rod arranged on the circumferential side of the first spray ring and used to connect the bracket, and a plurality of first nozzles arranged on the inner side of the first spray ring and evenly spaced along the circumferential side of the first spray ring.

[0023] By adopting the above technical solution, external resin glue is injected into the first spray ring through the glue injection pump, and the resin glue is sprayed toward the inside of the first spray ring through the first nozzle in the first spray ring, so that the glass fiber passing through the inside of the first spray ring is sprayed with resin glue.

[0024] The present invention is further configured as follows: the spray assembly also includes a second spray ring whose outer diameter is smaller than that of the first spray ring and is located on the upper side of the first spray ring, and a plurality of second nozzles arranged on the inner side of the second spray ring and evenly spaced along the circumference of the second spray ring; the second spray ring is also connected to the glue injection pump through a hose.

[0025] By adopting the above technical solution, the outer diameter of the second spray ring is smaller than the outer diameter of the first spray ring, so the resin glue sprayed from the second nozzle of the second spray ring can be closer to the center of the first spray ring and the second spray ring, which is beneficial to effectively spray various positions of the falling glass fiber and avoids the situation where the glass fiber passing through the center of the first spray ring and the second spray ring cannot be well sprayed.

[0026] The present invention is further configured as follows: a barrier curtain for wrapping around the spray assembly and the guide cylinder is provided on the peripheral side of the bracket.

[0027] By adopting the above technical solution, a barrier curtain is wrapped around the spray assembly and the guide cylinder to block the resin glue splashed in the spray assembly and the glass fiber dropped from the guide cylinder accessories, thereby preventing the resin glue and glass fiber from polluting the factory environment.

[0028] The present invention is further configured as follows: the barrier curtain is made of a transparent flexible plastic material.

[0029] By adopting the above technical solution, the barrier curtain is made of transparent flexible plastic material, and the operation of the spraying assembly and the guide cylinder can be observed through the barrier curtain, which is beneficial for real-time observation by operators.

[0030] The beneficial effects of the present invention are as follows: after the glass fibers are discharged from the lower side of the centrifuge, they first pass through the spray assembly, and the resin glue can be evenly sprayed on the falling glass fibers through the first nozzle on the first spray ring and the second nozzle on the second spray ring, and then the bonded glass fibers can fall into the guide cylinder, wherein the guide cylinder includes a first cylinder body in a funnel shape with a larger upper portion and a smaller lower portion, and a second cylinder body arranged at the lower end of the first cylinder body and having a rectangular cross section, the first cylinder body can guide the falling glass fibers, so that the glass fibers gather in the second cylinder body and fall;

[0031] At the same time, since the upper end of the first cylinder is rotatably connected to the bracket, after the driving motor drives the rotating arm to rotate, the convex shaft at one end of the rotating arm away from the driving motor is embedded in the long strip hole of the connecting plate, and since one end of the connecting arm is connected to the connecting plate and the other end is connected to the rectangular frame, and the connecting arm passes through the guide sleeve, the circular motion of the convex shaft can drive the connecting arm and the rectangular frame to translate back and forth left and right, wherein the rectangular frame is used for the second cylinder to pass through, and the width of the rectangular frame is greater than the width of the cross section of the second cylinder, and the rectangular frame that translates left and right can drive the second cylinder to swing left and right, thereby realizing the swinging laying of glass fiber on the cotton collecting conveyor belt;

[0032] When it is necessary to adjust the left-right swing angle of the second cylinder, the adjusting motor is used to drive the threaded shaft to rotate. Since the slider at the end of the convex shaft is embedded in the long strip mouth, and the threaded hole on the slider is used for the threaded shaft to be threadedly connected, the forward and reverse rotation of the threaded shaft can drive the slider and the convex shaft to move back and forth along the long strip mouth, thereby adjusting the diameter of the convex shaft making a circular motion. Subsequently, the left-right translation distance of the rectangular frame can be changed by changing the diameter of the convex shaft making a circular motion, and finally the left-right swing angle of the second cylinder can be adjusted, so that glass wool of different widths can be laid on the cotton collecting conveyor belt.

[0033] At the same time, when the circular motion of the convex shaft drives the second cylinder to swing to the left, the third connecting rod will swing upward with the rotation of the output shaft of the driving motor, and then the third connecting rod can contact the second connecting rod and drive the second connecting rod to swing upward. At this time, the second connecting rod can drive the rotating shaft to rotate and drive the fixed arm to swing, and the reset spring is stretched at the same time; as the convex shaft continues to drive the second cylinder to swing to the left, when the second cylinder swings to the left to the extreme position, the upper part of the first cylinder is close to the initial position of the knocking ball. At this time, the third connecting rod is just separated from the second connecting rod. With the reset of the reset spring, the reset spring can drive the rotating shaft to rotate in the opposite direction and drive the fixed arm to swing in the opposite direction. Then the knocking ball at the end of the rotating shaft can bounce back to the initial position. At this time, the knocking ball can hit the inclined upper outer wall of the first cylinder, and the glass fiber attached to the upper inner wall of the first cylinder can be vibrated off by the vibration action of the knocking ball, which can finally help the glass fiber to fall efficiently from the guide cylinder.

[0051] Principle: After the glass fibers are discharged from the lower side of the centrifuge 2, they first pass through the spray assembly 3, and the resin glue can be evenly sprayed on the falling glass fibers through the first nozzle 34 on the first spray ring 31 and the second nozzle 36 on the second spray ring 35. Then, the bonded glass fibers can fall into the guide cylinder 5. Since the guide cylinder 5 includes a first cylinder body 51 with a funnel shape that is larger at the top and smaller at the bottom, and a second cylinder body 52 with a rectangular cross-section that is arranged at the lower end of the first cylinder body 51, the first cylinder body 51 can guide the falling glass fibers, so that the glass fibers gather in the second cylinder body 52 and fall.

[0052] At the same time, since the upper end of the first cylinder 51 is rotatably connected to the bracket 1, after the driving motor 67 drives the rotating arm 68 to rotate, the convex shaft 69 at one end of the rotating arm 68 away from the driving motor 67 is embedded in the long hole 64 of the connecting plate 63, and since one end of the connecting arm 65 is connected to the connecting plate 63 and the other end is connected to the rectangular frame 66, and the connecting arm 65 passes through the guide sleeve 62, the circular motion of the convex shaft 69 can drive the connecting arm 65 and the rectangular frame 66 to translate back and forth left and right, wherein the rectangular frame 66 is used for the second cylinder 52 to pass through, and the width of the rectangular frame 66 is greater than the width of the cross-section of the second cylinder 52, and the rectangular frame 66 that translates left and right can drive the second cylinder 52 to swing left and right, thereby realizing the swinging laying of glass fiber on the cotton collecting conveyor belt 4.

[0053] When it is necessary to adjust the left and right swing angle of the second cylinder 52, the adjusting motor 683 is used to drive the threaded shaft 682 to rotate. Since the slider 691 at the end of the convex shaft 69 is embedded in the long strip mouth 681, and the threaded hole 692 on the slider 691 is threadedly connected to the threaded shaft 682, the forward and reverse rotation of the threaded shaft 682 can drive the slider 691 and the convex shaft 69 to move back and forth along the long strip mouth 681, thereby adjusting the diameter of the circular motion of the convex shaft 69, and then the left and right translation distance of the rectangular frame 66 can be changed by changing the diameter of the circular motion of the convex shaft 69, and finally the left and right swing angle of the second cylinder 52 can be adjusted, so that glass wool of different widths can be laid on the cotton collection conveyor belt 4.

[0054] At the same time, when the circular motion of the convex shaft 69 drives the second cylinder 52 to swing leftward (refer to Figure 6 and 7 ), the third connecting rod 79 will swing upward with the rotation of the output shaft of the driving motor 67, and then the third connecting rod 79 can abut against the second connecting rod 78 and drive the second connecting rod 78 to swing upward, at this time, the second connecting rod 78 can drive the rotating shaft 72 to rotate and drive the fixed arm 75 to swing, and the reset spring 76 is stretched at the same time; as the convex shaft 69 continues to drive the second cylinder 52 to swing left, when the second cylinder 52 swings left to the extreme position, the upper part of the first cylinder 51 is close to the initial position of the knocking ball 74, and at this time the third connecting rod 79 can abut against the second connecting rod 78 and drive the second connecting rod 78 to swing upward, and at this time, the second connecting rod 78 can drive the rotating shaft 72 to rotate and drive the fixed arm 75 to swing, and at the same time, the reset spring 76 is stretched; as the convex shaft 69 continues to drive the second cylinder 52 to swing left, when the second cylinder 52 swings left to the extreme position, the upper part of the first cylinder 51 is close to the initial position of the knocking ball 74, and at this time The connecting rod 79 is just separated from the second connecting rod 78. With the reset of the reset spring 76, the reset spring 76 can drive the rotating shaft 72 to rotate in the opposite direction and drive the fixed arm 75 to swing in the opposite direction. Then the knocking ball 74 at the end of the rotating shaft 72 can bounce back to the initial position. At this time, the knocking ball 74 can hit the upper outer wall of the inclined first cylinder 51. The glass fiber attached to the upper inner wall of the first cylinder 51 can be vibrated off through the vibration effect of the knocking ball 74, which can finally help the glass fiber to fall efficiently from the guide cylinder 5.
