A prepreg device for high-temperature release fiberglass cloth

Abstract

The present invention relates to the technical field of prepreg, and particularly relates to a prepreg device for high-temperature release fiberglass cloth. In this solution, the head of the fiberglass cloth is fed towards the meshing direction of conveyor belt two and conveyor belt one. At this time, the edge fabrics on the front and back sides of the fiberglass cloth will be clamped by the front and rear groups of conveyor belt two and conveyor belt one. Since the joint of conveyor belt two and conveyor belt one is matched by the pressing protrusion and the pressing opening, the edge fabrics on the front and back sides of the fiberglass cloth can be locked. As the motor continues to rotate, the fiberglass cloth will move along with conveyor belt two. In this way, the fiberglass cloth can automatically enter the inside of the dipping tank and pass through the prepreg solution. Compared with the prior art of manually threading the head of the cloth around multiple conveyor rollers to achieve the prepreg of the fiberglass cloth, the efficiency is greatly improved. At the same time, the artificial pollution of the prepreg solution is further reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of prepreg, and particularly relates to a prepreg device for high-temperature release fiberglass cloth. Background Art

[0002] Fiberglass cloth is mainly used for heat insulation, fire prevention, and flame retardancy; when exposed to flame combustion, it absorbs a large amount of heat and can prevent the flame from passing through and isolate the air; before the fiberglass cloth is used, it needs to be pretreated to ensure the cleanliness and smoothness of its surface, and then the pretreated fiberglass cloth is immersed in the prepreg solution one by one to make it fully infiltrate and absorb the solution;

[0003] However, in actual use of the existing prepreg operation, when the fiber cloth first enters the glue tank, the "cloth head" (the free end located on the outer side of the cloth roll when the cloth is wound) needs to pass through the roller first, and then pass out from the other end of the glue tank; such manual operation is time-consuming and laborious, and it is also easy to contaminate the prepreg solution;

[0004] Secondly, since the fiber cloth is pulled and conveyed along its length direction during prepreg; at this time, wrinkles are easily formed along the width direction of the fiber cloth surface; when the wrinkles cannot be flattened in time, the phenomenon of uneven sizing will occur;

[0005] Furthermore, there will also be a phenomenon that one side of the fiber cloth is soaked and the other side is not soaked, and the phenomenon of uneven sizing will affect the quality of the finished product. Summary of the Invention

[0022] Beneficial effects compared with the prior art:

[0023] 1. In this solution, the head of the fiberglass cloth is fed in the meshing direction of the second conveyor belt and the first conveyor belt; at this time, the edge fabrics on the front and rear sides of the fiberglass cloth will be clamped by the front and rear groups of the second conveyor belt and the first conveyor belt; since the fitting part of the second conveyor belt and the first conveyor belt is matched by the pressing protrusion and the pressing opening; in this way, the edge fabrics on the front and rear sides of the fiberglass cloth can be locked; as the motor continues to rotate; the fiberglass cloth will move along with the second conveyor belt; in this way, the fiberglass cloth can automatically enter the inside of the dipping tank and pass through the pre-dipping glue; compared with the prior art of manually threading the head around multiple conveying rollers to pre-dip the fiberglass cloth, the efficiency is greatly improved; at the same time, the artificial pollution to the pre-dipping glue is further reduced;

[0024] 2. In this solution, the hexagonal nut is clamped by the wrench, and then the rotation direction of the bidirectional screw is adjusted; in this way, since the two ends of each expansion plate are respectively limited by the front shaft end cover and the rear shaft end cover, when the bidirectional screw is rotated, the two nuts will approach each other; under the action of the connecting rod, the expansion plate is displaced radially outward, and then the inner wall of the elastic sleeve is extruded to make its diameter larger; since the expansion plates are arranged at intervals in the elastic sleeve; in order to ensure that the elastic sleeve has a certain roundness, the elastic sleeve is inflated through the connection of high-pressure gas and the ventilation pipe to ensure its roundness; in this way, the fiberglass cloth is flattened along the width direction, preventing wrinkles from occurring during pre-dipping, and thus avoiding the situation of insufficient pre-dipping;

[0025] 3. Under the action of conveyor belt 1, the front shaft seal cover and the rear shaft seal cover disclosed in this solution move, thereby driving the outer cylinder and the long strip valve core inside the outer cylinder to rotate; when the long strip valve core rotates to the uppermost working position, at this time, the ball head at the front end of the long strip valve core at this working position cooperates with the convex platform; at this time, the convex platform will squeeze the ball head, at this time the spring is compressed, and then the long strip valve core moves backward; at this time, the apertures of the spray holes and the circulation holes coincide, and the pre-impregnated glue liquid inside the outer cylinder will spray upward and align with the fiberglass cloth; the glue liquid with a certain pressure will accelerate the penetration into the interior of the fiberglass cloth.

[0026] 4. For the two groups of pressure rollers disclosed in this solution, when the sliding frame reciprocates, it drives the pressure rollers to reciprocate above the fiberglass cloth; and then rolls back and forth on the top of the pre-impregnated fiberglass cloth; so that the pre-impregnated glue can better enter the interior of the fiberglass cloth; at the same time, both ends of the stirring assembly are meshed and connected with conveyor belt 1; in this way, when conveyor belt 1 rotates, it can drive the stirring assembly to rotate on its own; there are blades around the stirring assembly, which can stir and flow the pre-impregnated glue liquid while rotating; preventing it from precipitating.

Specific embodiments

[0041] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. Additionally, in order to more clearly describe the present invention, components not connected to the invention will be omitted from the drawings;

[0042] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology. The general idea is as follows: Embodiment 1

[0043] Please refer to Figure 1 and Figure 2As shown in the figure, this embodiment introduces the specific structure of a pre-impregnation device for high-temperature release fiberglass cloth, including an impregnation tank 1, a conveying device 2, and a fiberglass cloth 4. A conveying device 2 is arranged inside the impregnation tank 1, and a pre-impregnation glue solution is contained inside the impregnation tank 1. Guide plates 11 are respectively arranged at the left and right ends of the impregnation tank 1 for guiding the fiberglass cloth 4 when it is just pre-impregnated.

[0044] Please refer to Figure 3 As shown in the figure, the conveying device 2 includes a first roller 21, a second roller 22, a third roller 23, a fourth roller 24, a flattening roller 6, and a spraying and impregnating roller 7. There are two flattening rollers 6 and two spraying and impregnating rollers 7, both of which are arranged at the bottom of the impregnation tank 1. The first roller 21, the third roller 23, and the two flattening rollers 6 form a group, where the first roller 21 and the third roller 23 are respectively arranged on the left and right sides at the top of the impregnation tank 1; the two flattening rollers 6 are symmetrically arranged on the left and right sides at the bottom of the impregnation tank 1. Conveyor belts two 26 are arranged on the outer sides of the front and rear ends of the first roller 21, the third roller 23, and the two flattening rollers 6. When the conveyor belt two 26 rotates, it can drive the first roller 21, the third roller 23, and the two flattening rollers 6 to rotate self-rotationally.

[0045] The second roller 22, the fourth roller 24, and the two spraying and impregnating rollers 7 form a group, where the first roller 21 and the third roller 23 are respectively arranged on the left and right sides at the top of the impregnation tank 1 and are respectively located directly below the first roller 21 and the third roller 23; the two spraying and impregnating rollers 7 are symmetrically arranged on the left and right sides at the bottom of the impregnation tank 1 and are respectively located directly below the flattening rollers 6. Conveyor belts one 25 are arranged on the outer sides of the front and rear ends of the second roller 22, the fourth roller 24, and the two spraying and impregnating rollers 7. When the conveyor belt one 25 rotates, it can drive the first roller 21, the third roller 23, and the two flattening rollers 6 to rotate self-rotationally.

[0046] The mutually engaging sides of the conveyor belt two 26 and the conveyor belt one 25 can clamp the edges of the fiberglass cloth 4.

[0047] The first roller 21 is a driving roller, and the first roller 21 is driven by an external motor. Its rotation can drive the third roller 23 and the two flattening rollers 6 to rotate self-rotationally through the conveyor belt two 26. Since there is friction between the conveyor belt two 26 and the conveyor belt one 25 when they are mutually attached, when the conveyor belt two 26 rotates, it can drive the conveyor belt one 25 to rotate; thereby indirectly driving the second roller 22, the fourth roller 24, and the two spraying and impregnating rollers 7.

[0048] A certain gap is reserved when the flattening roller 6 and the spraying and impregnating roller 7 are arranged. The main factor for the transmission and engagement of the two ends below the spraying and impregnating roller 7 with the conveyor belt one 25 is that the rotation directions of the flattening roller 6 and the spraying and impregnating roller 7 are opposite to prevent friction on the fiberglass cloth 4 due to different rotation directions of the two.

[0049] Please refer to Figure 8As shown in the figure, on the end face of the second conveyor belt 26 close to the first conveyor belt 25 and away from the inner wall of the dipping tank 1, a pressing opening 262 is provided; on the end face of the first conveyor belt 25 close to the second conveyor belt 26 and away from the inner wall of the dipping tank 1, a pressing protrusion 252 is provided; the pressing protrusion 252 and the pressing opening 262 are matched; through the cooperation of the pressing protrusion 252 and the pressing opening 262, the edges of the fiberglass cloth 4 can be better clamped;

[0050] On one side of the second conveyor belt 26 opposite to the pressing opening 262, a first engaging portion 261 is provided, and on one side of the first conveyor belt 25 opposite to the pressing protrusion 252, a second engaging portion 251 is provided; the second conveyor belt 26 is engaged and matched with the ends of the first roller 21, the third roller 23, and the two flattening rollers 6 through the first engaging portion 261; the first conveyor belt 25 is engaged and matched with the ends of the second roller 22, the fourth roller 24, and the two spraying and dipping rollers 7 through the second engaging portion 251; the thickness and height of the first engaging portion 261 and the second engaging portion 251 are the same; this prevents the second conveyor belt 26 and the first conveyor belt 25 from falling off during transmission;

[0051] Specifically, first, an appropriate amount of pre-dipping glue solution is injected into the dipping tank 1; the end of the fiberglass cloth 4 to be pre-dipped is laid flat on the top of the left guiding plate 11, and then the motor driving the first roller 21 is started. When the motor starts, at this time, the second conveyor belt 26 rotates counterclockwise. Since the outer ring parts of the second conveyor belt 26 and the first conveyor belt 25 are in contact, there is friction before; at this time, the first conveyor belt 25 rotates clockwise; then the end of the fiberglass cloth 4 is fed in the meshing direction of the second conveyor belt 26 and the first conveyor belt 25; at this time, the edge fabrics on the front and back sides of the fiberglass cloth 4 will be clamped by the front and back groups of the second conveyor belt 26 and the first conveyor belt 25; since the joint of the second conveyor belt 26 and the first conveyor belt 25 is matched by the pressing protrusion 252 and the pressing opening 262; in this way, the edge fabrics on the front and back sides of the fiberglass cloth 4 can be locked; as the motor continues to rotate; the fiberglass cloth 4 will move along with the second conveyor belt 26; in this way, the fiberglass cloth 4 can automatically enter the inside of the dipping tank 1 and pass through the pre-dipping glue solution; compared with the prior art of manually threading the end of the cloth around multiple conveying rollers to realize the pre-dipping of the fiberglass cloth 4, the efficiency is greatly improved; at the same time, the artificial pollution to the pre-dipping glue solution is further reduced; Embodiment Two

[0052] This embodiment is an improvement based on Embodiment One:

[0053] Please refer to Figure 6 and Figure 7As shown in the figure, in order to further flatten the fiberglass cloth 4 along the width direction to prevent wrinkles from occurring during pre-impregnation; in this embodiment, the flattening roller 6 includes a rear shaft end cover 61, an elastic sleeve 62 and a front shaft end cover 63; an elastic sleeve 62 is fixedly arranged between the rear shaft end cover 61 and the front shaft end cover 63; the shaft end parts of the front shaft end cover 63 and the rear shaft end cover 61 are respectively rotatably connected to the wall surface of the dipping tank 1; wherein, a clamping groove one 611 and a clamping groove two 631 are respectively arranged on the outer sides of the rear shaft end cover 61 and the front shaft end cover 63; wherein, the clamping groove one 611 and the clamping groove two 631 are matched with the clamping part one 261;

[0054] A skeleton 65 is arranged inside the elastic sleeve 62; the skeleton 65 includes a bidirectional screw 651, and the bidirectional screw 651 is rotatably connected to the rear shaft end cover 61; nuts 652 are respectively threadedly connected to the outer sides of the threads with two different helix directions in the middle of the bidirectional screw 651, and a plurality of connecting rods 653 are arranged around the nuts 652, wherein the outer ends of the connecting rods 653 arranged at the same angular position on the outer sides of the nuts 652 located on the threads with two different helix directions are hinged with an expansion plate 654; the side of the expansion plate 654 close to the elastic sleeve 62 is arc-shaped; the front and rear ends of the expansion plate 654 are respectively slidably connected to the front shaft end cover 63 and the rear shaft end cover 61;

[0055] The outer end of the bidirectional screw 651 close to the rear shaft end cover 61 has a hexagonal nut 6511; when it is necessary to adjust the size of the expansion plate 654 opening outwards, first, the rear shaft end cover 61 needs to be in a static state, then the hexagonal nut 6511 is clamped by a wrench, and then the rotation direction of the bidirectional screw 651 is adjusted; in this way, since the two ends of each expansion plate 654 are respectively limited by the front shaft end cover 63 and the rear shaft end cover 61, when the bidirectional screw 651 is rotated, the two nuts 652 will approach each other; under the action of the connecting rods 653, the expansion plate 654 is further displaced radially outwards, thereby squeezing the inner wall of the elastic sleeve 62 and making its diameter larger;

[0056] As an implementable manner, a plurality of sliding grooves two 632 are radially arranged on the inner wall of the front shaft end cover 63, and each sliding groove two 632 corresponds to an expansion plate 654 inside; the front end of the expansion plate 654 is slidably connected to the front shaft end cover 63 through the sliding groove two 632;

[0058] A through hole is arranged in the middle of the elastic sleeve 62, and a ventilation pipe 64 is rotatably connected to the front side of the through hole; by introducing high-pressure gas into the elastic sleeve 62, the diameter of the elastic sleeve 62 can be increased under the action of the skeleton 65, and at the same time, it can be made more round;

[0059] Specifically, since the fiberglass cloth 4 is clamped and fixed by the second conveyor belt 26 and the first conveyor belt 25 along the two side edges of the width; therefore, in order to prevent the fiberglass cloth 4 from having wrinkles along the width direction; the operator can adjust the diameter of the flattening roller 6 to achieve the tensioning of the middle of the fiberglass cloth 4 along the width direction; in this way, wrinkles are prevented from appearing; first, the rear end cover 61 of the shaft needs to be in a static state, then the hexagonal nut 6511 is clamped by a wrench, and then the rotation direction of the bidirectional screw 651 is adjusted; in this way, since both ends of each expansion plate 654 are limited by the front end cover 63 and the rear end cover 61 of the shaft respectively, when the bidirectional screw 651 is rotated, the two nuts 652 will approach each other; under the action of the connecting rod 653, the expansion plate 654 is displaced radially outward, and then the inner wall of the elastic sleeve 62 is extruded to make its diameter larger; since the expansion plates 654 are arranged at intervals in the elastic sleeve 62; in order to ensure that the elastic sleeve 62 has a certain roundness, the inside of the elastic sleeve 62 is inflated by connecting high-pressure gas to the air pipe 64 to ensure its roundness; in this way, the flattening of the fiberglass cloth 4 along the width direction is realized, and wrinkles are prevented from appearing during pre-impregnation, thus avoiding the situation of insufficient pre-impregnation.
