Description

Technical Field

[0001] The present invention belongs to the technical field of glass fiber drawing, and particularly relates to an efficient glass fiber drawing machine. Background Art

[0002] Glass fiber is an inorganic non-metallic material with good performance, having advantages such as high heat resistance and good corrosion resistance. Therefore, glass fiber has a wide range of uses in production and life. A drawing machine is a commonly used device for producing glass fiber. The process of producing glass fiber by a drawing machine is as follows: first, glass balls are melted at high temperature, then drawn, and finally wound up.

[0003] The existing drawing machines in actual production have the following problems: when using devices such as a melting tank to melt glass balls at high temperature, a feeding mechanism is needed to add glass balls to the melting tank. However, since a very high temperature needs to be maintained inside the melting tank, the temperature at the feeding port of the melting tank is extremely high, resulting in a pile-up of glass balls at one end of the feeding port. It is very likely that the glass balls will melt at the feeding port, and a part of the melted glass balls will adhere to the feeding port, thus causing blockage of the feeding port, which greatly affects the production efficiency of glass fiber.

[0004] To solve the above problems, a new type of glass fiber drawing machine is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient glass fiber drawing machine, which can effectively avoid blockage at the feeding port of the melting tank, thereby ensuring the production efficiency of the drawing machine.

[0006] To achieve the above purpose, the present invention provides an efficient glass fiber drawing machine, including a feeding mechanism, a melting tank, and a drawing mechanism connected in sequence. The drawing mechanism is arranged adjacent to a winding mechanism. The feeding mechanism includes a storage bin, the bottom opening of the storage bin is correspondingly arranged above the feeding end of a flattening tray, the bottom height of the flattening tray gradually decreases from the feeding end to the discharging end of the flattening tray. A limiting plate is arranged in the flattening tray between the feeding end and the discharging end. The distance between the limiting plate and the bottom of the flattening tray gradually decreases from the feeding end to the discharging end. The minimum distance between the limiting plate and the bottom of the flattening tray is greater than the diameter of the glass ball and less than twice the diameter of the glass ball. The discharging end is connected to a plurality of diversion grooves, the size of the diversion grooves gradually decreases from the direction close to the discharging end to the direction away from the discharging end. The end of the diversion groove is adaptively connected to a guiding pipe, the diameter of the guiding pipe is greater than the diameter of the glass ball and less than twice the diameter of the glass ball. The pipe wall of the guiding pipe is provided with a hollowed-out thread. The melting tank is provided with feeding ports corresponding to the guiding pipes one by one.

[0007] Preferably, a quantitative feeding member is provided between the limiting plate and the discharging end of the flattening tray. The quantitative feeding member includes a rotating shaft, one end of the rotating shaft passes through the flattening tray and is connected to a feeding motor. On the curved outer wall of the rotating shaft, there is a set of dial rods evenly distributed along the length direction of the rotating shaft. Each set of dial rods includes four dial rods evenly distributed along the circumferential direction of the rotating shaft. Two adjacent dial rods on the rotating shaft along its circumferential direction are adapted to a glass bead structure, and the distance between two adjacent dial rods on the rotating shaft along its length direction is less than the diameter of a glass bead.

[0008] Preferably, an impregnating agent adding port is provided on the melting tank. The outlet of a delivery pipe is correspondingly arranged directly above the impregnating agent adding port. A flow detector and a control valve are provided on the delivery pipe.

[0009] Preferably, the connection part between two adjacent flow dividing grooves is a hem folded towards the flattening tray.

[0010] Preferably, the winding mechanism includes a winding roller, a cooling roller and a cooling fan. The winding roller is rotatably connected to a winding frame, and the winding roller is connected to a winding motor fixed on the winding frame. The cooling roller is fixed between the winding roller and the wire drawing mechanism, and the cooling roller is arranged parallel to the winding roller. The cooling roller is filled with a coolant. One end of the cooling roller is connected to a liquid inlet pipe, and the other end of the cooling roller is connected to a liquid outlet pipe. The cooling fan is arranged opposite to the wire outlet of the wire drawing mechanism. The wire inlet of the wire drawing mechanism is connected to the wire outlet of the melting tank.

[0011] Preferably, a support seat is fixedly connected to the box plate of the melting tank. The top of the support seat is in contact connection with the guiding pipe, and the end of the guiding pipe is correspondingly arranged above the feeding port.

[0012] Therefore, an efficient glass fiber drawing machine adopting the above structure in the present invention has the following beneficial effects:

[0013] 1. The cooperation of the flattening tray, the limiting plate, the flow dividing grooves and the guiding pipe is used to realize the transportation of glass beads, which can avoid blockage at the feeding port of the melting tank, and thus ensure the production efficiency of the drawing machine;

[0014] 2. The hollowed-out threads can dissipate heat from the guiding pipe, block the heat conduction from the melting tank to the flow dividing grooves, avoid the melting of glass beads in the guiding pipe or even in the flow dividing grooves, and at the same time can fill the deformation caused by thermal expansion and contraction of the guiding pipe, which is beneficial to the smooth transportation of glass beads;

[0022] 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.

[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment

[0025] Refer to Figures 1-4As shown in the figure, this embodiment provides an efficient glass fiber drawing machine, which includes a feeding mechanism, a melting tank 1, and a drawing mechanism 2 connected in sequence. The drawing mechanism 2 is arranged adjacent to the winding mechanism 12. The feeding mechanism includes a silo 3, and the bottom opening of the silo 3 is correspondingly arranged above the feeding end of the flattening tray 4. The bottom height of the flattening tray 4 gradually decreases from the feeding end to the discharging end of the flattening tray 4, so that the glass beads can move from the feeding end to the discharging end under the action of gravity. A limiting plate 5 is arranged in the flattening tray 4 between the feeding end and the discharging end, and the distance between the limiting plate 5 and the bottom of the flattening tray 4 gradually decreases from the feeding end to the discharging end. The inclined setting of the limiting plate 5 can prevent the glass beads from moving to the discharging end above the limiting plate 5. The minimum distance between the limiting plate 5 and the bottom of the flattening tray 4 is greater than the diameter of the glass ball and less than twice the diameter of the glass ball, so that the glass beads can move in a single layer state after passing through the limiting plate 5. The discharging end is connected to a plurality of shunt grooves 6, and the shunt grooves 6 are used to realize the multi-channel connection between the flattening head plate and the melting tank 1, thereby improving the conveying efficiency of the glass beads.

[0026] The size of the shunt groove 6 gradually decreases from the direction close to the discharging end to the direction far from the discharging end, and the end of the shunt groove 6 is adaptively connected to the guiding tube 7. The connection mode between the guiding tube 7 and the shunt groove 6 can be specifically: the outer wall of the guiding tube 7 is fixedly connected to the connecting block, and the connecting block is detachably connected to the shunt groove 6 by bolts. The diameter of the guiding tube 7 is greater than the diameter of the glass ball and less than twice the diameter of the glass ball. The height of the guiding tube 7 gradually decreases from the end close to the shunt groove 6 to the end close to the melting tank 1, so that the glass beads can move from the shunt groove 6 to the melting tank 1 under the action of gravity. An inlet 8 corresponding to the guiding tube 7 is provided on the melting tank 1, and the diameter of the inlet 8 can be greater than the diameter of one glass bead and less than the sum of the diameters of two glass beads, avoiding heat dissipation in the melting tank 1 and at the same time ensuring that the glass beads can enter the melting tank 1. The guiding tube 7 can realize the single conveying of the glass beads, thereby avoiding the accumulation of the glass beads at the inlet 8 of the melting tank 1. The pipe wall of the guiding tube 7 is provided with a hollow thread, which can dissipate heat from the guiding tube 7, block the heat conduction from the melting tank 1 to the shunt groove 6, avoid the melting of the glass beads in the guiding tube 7 or even the shunt groove 6, and at the same time can fill the deformation of the guiding tube 7 caused by thermal expansion and contraction, which is beneficial to the smooth transmission of the glass beads.

[0027] During use, the glass beads fall from the silo 3 onto the flattening tray 4. Through the design of the inclined bottom surface of the flattening head plate, the glass beads can move from the feeding end to the discharging end under the action of gravity. During the movement, under the limiting action of the limiting plate 5, the glass beads at the discharging end move in a single layer state. As a result, when the glass beads enter the guiding tube 7 through the shunt groove 6, the inlet of the guiding tube 7 will not be blocked, and the guiding tube 7 can convey the glass beads to the melting tank 1 in a one-by-one arrangement, avoiding the blockage at the inlet 8 of the melting tank 1.

[0028] In a further preferred embodiment, a quantitative feeding member 9 is provided between the limiting plate 5 and the discharging end of the flattening tray 4. The quantitative feeding member 9 includes a rotating shaft 91, and one end of the rotating shaft 91 passes through the flattening tray 4 and is connected to the feeding motor 10. On the curved outer wall of the rotating shaft 91, a set of dial rods 92 are evenly distributed along the length direction of the rotating shaft 91. Each set of dial rods 92 includes four dial rods 92 evenly distributed along the circumferential direction of the rotating shaft 91. Two adjacent dial rods 92 on the rotating shaft 91 along its circumferential direction are adapted to a glass ball structure, and the distance between two adjacent dial rods 92 on the rotating shaft 91 along its length direction is less than the diameter of a glass ball.

[0029] During use, by changing the rotation speed of the feeding motor 10, the transmission amount of glass beads per unit time can be changed.

[0030] In a further preferred embodiment, an impregnating agent adding port 11 is provided on the melting tank 1, and the outlet of the conveying pipe 15 is correspondingly arranged directly above the impregnating agent adding port 11. A flow detector and a control valve are provided on the conveying pipe 15. By the combined use of the flow detector and the control valve, the addition amount of the impregnating agent per unit time can be effectively controlled. The combined use of the feeding motor 10, the flow detector and the control valve can control the ratio of glass beads to the impregnating agent, increase the melting efficiency of glass beads by using the impregnating agent, and accurately control the addition amount of the impregnating agent at the same time, saving costs.

[0031] In a further preferred embodiment, the connection part between two adjacent flow dividing grooves 6 is a hem edge facing the flattening tray 4. The hem edge can effectively prevent glass beads from accumulating and staying at the connection part between two adjacent flow dividing grooves 6.

[0032] In a further preferred embodiment, the winding mechanism 12 includes a winding roller 121, a cooling roller 122 and a heat dissipation fan 123. The winding roller 121 is rotatably connected to the winding frame 124, and the winding roller 121 is connected to a winding motor 125 fixed on the winding frame 124. The cooling roller 122 is fixed between the winding roller 121 and the wire drawing mechanism 2, and the cooling roller 122 is arranged parallel to the winding roller 121. The cooling roller 122 is filled with a coolant. One end of the cooling roller 122 is connected to the liquid inlet pipe 13, and the other end of the cooling roller 122 is connected to the liquid outlet pipe. The heat dissipation fan 123 is arranged opposite to the wire outlet of the wire drawing mechanism 2, and the wire inlet of the wire drawing mechanism 2 is connected to the wire outlet of the melting tank 1.

[0033] During use, the molten glass in the melting tank 1 enters the wire drawing mechanism 2. The wire drawing mechanism 2 is a prior art. By using the wire drawing mechanism 2, the molten glass can be processed into glass fiber filaments. After the glass fiber filaments come out from the wire outlet of the wire drawing mechanism 2, they are cooled through the air cooling effect of the heat dissipation fan 123 and the heat exchange effect of the cooling roller 122, and finally wound into a roll by the winding roller 121.

[0034] A further preferred solution is that a support base 14 is fixedly connected to the box plate of the melting box 1. The top of the support base 14 is in contact connection with the guiding pipe 7, and the end of the guiding pipe 7 is correspondingly arranged above the feeding port 8. The support base 14 can support the guiding pipe 7, so that the end of the guiding pipe 7 does not contact the feeding port 8 of the melting box 1, further reducing the heat transfer from the melting box 1 to the guiding pipe 7. In addition, by changing the fixed position of the support base 14 and the melting box 1, the outlet position of the guiding pipe 7 can be changed to ensure that the glass beads can smoothly enter the melting box 1 through the feeding port 8 from the guiding pipe 7.

[0035] Therefore, the high-efficiency glass fiber drawing machine with the above structure in the present invention effectively avoids blockage at the feeding port 8 of the melting box 1, thereby ensuring the production efficiency of the drawing machine.
