Description

Technical Field

[0001] This utility model belongs to the technical field of prepreg release membrane separation, specifically relating to a fiber prepreg release membrane separation device. Background Technology

[0002] Fiber prepreg is a composite material intermediate formed by impregnating reinforcing fiber materials such as carbon fiber and glass fiber with matrix resins such as epoxy resin and phenolic resin. It is widely used in aerospace, rail transportation, new energy and other fields. In order to prevent the prepreg from sticking together during storage, transportation and early processing, its upper and lower surfaces are usually covered with release film to play a role in isolation and protection. Before the subsequent processing of the prepreg, these release films need to be peeled off from the surface of the prepreg to ensure that the prepreg can be tightly bonded to other structural layers and guarantee the mechanical properties of the final product.

[0003] However, currently, the cooling and setting effect of prepreg is insufficient during the release film peeling process. Some devices only use unilateral cooling or the cooling temperature is uncontrollable, resulting in an overall high temperature of the prepreg. The resin viscosity is not sufficiently reduced, and the adhesion between the release film and the prepreg surface remains relatively large. Furthermore, the guide angle of the release film peeling mechanism is fixed and cannot be adjusted according to the cooling state of the prepreg. When the peeling angle is too large, the release film will generate a large pulling force on the surface of the prepreg during the peeling process. This not only easily causes the prepreg body to be stretched and deformed, but also removes the resin that is not fully set on the surface, resulting in resin waste. At the same time, it affects the stability of the resin content of the prepreg, ultimately leading to a significant decline in product quality. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a fiber prepreg release membrane separation device, thereby solving the technical problem of poor separation effect in existing fiber prepreg release membrane separation devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fiber prepreg release membrane separation device, comprising: The box has a receiving cavity, and the opposite side walls of the box are respectively provided with a feed inlet and a discharge outlet, and the feed inlet and the discharge outlet are both connected to the receiving cavity; A conveying assembly is rotatably mounted in the receiving cavity and is connected to the inlet and outlet. A pre-tightening assembly is installed inside the receiving cavity and connected to the conveying assembly; A cooling assembly is movable within the receiving cavity along a first direction; The separation component is rotatably mounted on the outer wall of the housing with the discharge port; An adjustment component is installed on the outer wall of the housing, and the adjustment component is used to adjust the vertical distance between the separation component and the fiber prepreg to be processed.

[0006] With the above structure, when using the fiber prepreg release film separation device provided by this utility model, the fiber prepreg to be processed is first conveyed from the inlet into the receiving cavity of the box. The fiber prepreg to be processed is then pushed into the conveying mechanism connected to the inlet. The conveying mechanism is then adjusted by the pre-tightening mechanism to clamp the fiber prepreg to be processed, ensuring a smooth entry and reducing the probability of wrinkles or deviations during initial conveying. The fiber prepreg to be processed continues to be pushed forward, and the conveying mechanism rotates synchronously, allowing the fiber prepreg to be processed to enter the cooling assembly. The cooling assembly cools and shapes the prepreg, reducing its viscosity and thus lowering the probability of the prepreg being stretched and deformed, and the resin being carried away when the release film is peeled off. The fiber prepreg to be processed continues to be pushed forward until it reaches the outlet, where the peeled release film is then removed. Connected to the separation assembly, rotating the separation assembly automatically peels off the prepreg from the release film and winds up the peeled release film. Simultaneously, it drives the peeled prepreg forward, pulling the subsequent prepreg to be processed back into the chamber from the feed inlet. This automatic peeling of the release film by the separation assembly improves the efficiency of release film peeling. The adjustment assembly allows for adjustment of the vertical distance between the separation assembly and the prepreg to be processed based on the viscosity and strength of the prepreg, thus adjusting the peeling angle of the release film. This further reduces the probability of the prepreg being stretched and deformed, and the resin being carried away. Therefore, the cooling and adjustment assemblies effectively reduce the probability of the prepreg being stretched and deformed, and the resin being carried away, resulting in a better peeling effect for the fiber prepreg release film separation device provided by this invention.

[0010] Furthermore, it also includes a stabilizer bar that can be slidably mounted on the housing along the first direction, with one end of the stabilizer bar extending into the housing and connected to the cooling plate, and the axis of the stabilizer bar being arranged along the first direction.

[0011] Furthermore, the number of cooling components is two, and the two cooling components are symmetrically arranged along the plane containing the second direction and the third direction, and the first direction, the second direction and the third direction are arranged perpendicular to each other in pairs.

Detailed Implementation

[0019] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0020] This embodiment provides a fiber prepreg release film separation device, which solves the technical problem of poor separation effect in existing fiber prepreg release film separation devices. The fiber prepreg release film separation device includes a housing 1, a conveying mechanism, a pre-tightening mechanism, a cooling assembly 4, a separation assembly 5, and an adjusting assembly 6, wherein: refer to Figure 1 — Figure 2The housing 1 has a receiving cavity 11, that is, the housing 1 is a hollow cuboid. The opposite side walls of the housing 1 are respectively provided with a feed inlet 12 and a discharge outlet 13. Optionally, the width of the feed inlet 12 and the discharge outlet 13 is greater than the width of the fiber prepreg to be processed, and the edges of the feed inlet 12 and the discharge outlet 13 are rounded to prevent the fiber prepreg to be processed from being scratched during the movement. Specifically, the feed inlet 12 and the discharge outlet 13 are arranged opposite to each other, and both the feed inlet 12 and the discharge outlet 13 are connected to the receiving cavity 11. Optionally, a support frame is also included, which is installed at the bottom of the housing 1. The support frame is a structural component made of high-strength alloy material, and the bottom of the support frame has an anti-slip pad. When the fiber prepreg release film separation device provided by this utility model is running at high speed, the probability of position displacement caused by vibration is reduced.

[0021] The conveying mechanism is rotatably installed inside the receiving cavity 11 and is connected to the inlet 12 and the outlet 13. The conveying mechanism is used to convey the fiber prepreg to be processed. In this way, the rotatably installed conveying mechanism makes it easier to convey the fiber prepreg to be processed.

[0022] The pre-tightening mechanism is installed inside the receiving cavity 11 and connected to the conveying mechanism. The pre-tightening mechanism uses the drive conveying mechanism to clamp and release the fiber prepreg to be processed. In this way, after the fiber prepreg to be processed is placed, the pre-tightening mechanism drives the conveying mechanism to clamp the fiber prepreg, thus preventing the release film from wrinkling during the movement of the fiber prepreg.

[0023] The cooling component 4 can be moved and installed in the receiving cavity 11 along a first direction. Optionally, the first direction is a vertical direction. The cooling component 4 is used to cool the fiber prepreg to be processed. In this way, by setting the movable cooling component 4, it is convenient to adjust the vertical distance between the cooling component 4 and the fiber prepreg to be processed according to the viscosity of the fiber prepreg to be processed, thereby improving the cooling efficiency and the utilization rate of the cooling component 4.

[0024] The separation component 5 is rotatably installed on the outer wall of the housing 1 with the discharge port 13. The separation component 5 is used to separate the release film from the fiber prepreg. In this way, the purpose of automatically peeling off the release film is achieved by setting the separation component 5.

[0025] The adjustment component 6 is installed on the outer wall of the housing 1. The adjustment component 6 is used to adjust the vertical distance between the separation component 5 and the fiber prepreg to be treated, that is, to adjust the peeling angle of the separation component 5. This makes it easy to adjust the peeling angle of the separation component 5 according to the viscosity of the fiber prepreg to be treated and the cavity. When the peeling angle is too low, the peeling force will generate a large shear stress on the interface between the resin and the release film, and at the same time, it will also generate a strong tensile stress on the fiber prepreg, pulling the prepreg. A suitable peeling angle can more efficiently destroy the interface adhesion, while the tensile effect on the prepreg body is minimal.

[0026] refer to Figure 3 The conveying mechanism includes two sets of conveying components, which are located at the inlet 12 and the outlet 13, respectively. This arrangement of two sets of conveying components prevents the fiber prepreg to be processed from shifting within the receiving cavity 11. Each conveying component includes two conveying rollers 2, both of which are rotatably installed within the housing 1. The two conveying rollers 2 can be moved along a first direction within the housing 1, and their axes are arranged along a second direction. The first and second directions are perpendicular to each other. In use, the fiber prepreg to be processed is clamped between the two conveying rollers 2, and the two rotatably installed conveying rollers 2 make it easier for the drive source to move the fiber prepreg to be processed within the receiving cavity 11.

[0027] refer to Figure 5 The pre-tightening assembly 3 includes two sets of pre-tightening assemblies 3, which are respectively connected to two sets of conveying assemblies. This allows the two sets of conveying assemblies to be driven by the two pre-tightening assemblies 3, making it easier to adjust the distance between the two conveying rollers 2 within the same conveying assembly. This facilitates adjusting the clamping force of the two conveying rollers 2 on the fiber prepreg to be processed. The pre-tightening assembly 3 includes a first screw 31, a second screw 32, a guide rod 33, a first moving block 34, and a second moving block 35, wherein: One end of the first screw 31 is rotatably mounted on the inner bottom wall of the housing 1, and the axis of the first screw 31 is set along the first direction.

[0028] One end of the second screw 32 extends into the housing 1 and is connected to the other end of the first screw 31. It is coaxially arranged with the first screw 31, and the rotation direction of the first screw 31 is opposite to that of the second screw 32. Optionally, the first screw 31 and the second screw 32 can be connected together by welding, bonding or hot melting. Of course, they can also be integrally formed.

[0029] The two ends of the guide rod 33 are respectively fixedly installed on the two opposite inner side walls of the housing 1, and are arranged parallel to each other with the first screw 31. The projections of the guide rod 33 and the first screw 31 in the first direction are located on two non-adjacent vertices of the same rectangle.

[0030] Optionally, there are two guide rods 33, which are centrally symmetrical, so that the force on the two guide rods 33 is more even.

[0031] One end of the first moving block 34 is provided with a first threaded hole adapted to the first screw 31 and a first guide hole adapted to the guide rod 33. The first screw 31 is rotatably installed in the first threaded hole, and the guide rod 33 is slidably installed in the first guide hole. One end of either of the two conveying rollers 2 is rotatably installed on the first moving block 34. Specifically, the inner side wall of the housing 1 is provided with a groove adapted to the conveying roller 2. The length direction of the groove is set along the first direction. The end of the conveying roller 2 away from the first moving block 34 is rotatably and slidably inserted into the groove. In this way, through the cooperation of the first moving block 34, the first screw 31 and the guide rod 33, when the first screw 31 is rotated, the first moving block 34 reciprocates on the first screw 31 and the guide rod 33. The setting of the guide rod 33 prevents the first moving block 34 from rotating with the rotation of the first screw 31.

[0032] One end of the second movable block 35 has a second threaded hole adapted to the second screw 32 and a second guide hole adapted to the guide rod 33. The second screw 32 is rotatably installed in the first threaded hole, and the guide rod 33 is slidably installed in the second guide hole. One end of the other conveying roller 2 is rotatably installed on the second movable block 35. Specifically, the end of the conveying roller 2 away from the second movable block 35 rotates and slides into the groove. Thus, through the cooperation of the second movable block 35, the second screw 32, and the guide rod 33, when the first screw 31 rotates, it drives the second screw 32 to rotate synchronously, causing the second movable block 35, the second screw 32, and the guide rod 33 to rotate synchronously. The reciprocating motion is achieved, and the guide rod 33 prevents the second moving block 35 from rotating with the rotation of the second screw 32. The first screw 31 and the second screw 32 are arranged in opposite directions. When the first screw 31 rotates, the first moving block 34 and the second moving block 35 move towards each other, thereby driving the two conveying rollers 2 to move synchronously towards each other, that is, the two conveying rollers 2 clamp the fiber prepreg to be processed. When the first screw 31 reverses, the first moving block 34 and the second moving block 35 move away from each other, thereby driving the two conveying rollers 2 to move synchronously away from each other, that is, the conveying rollers 2 release the fiber prepreg to be processed.

[0033] The fiber prepreg to be processed is compressed at the feed inlet 12 to prevent wrinkles and deviations during the initial conveying of the fiber prepreg. The fiber prepreg to be processed is compressed at the discharge outlet 13 to counteract end tension fluctuations and ensure that the fiber prepreg to be processed remains flat and compact throughout the entire processing.

[0034] Optionally, a rotating handle is also included, which is fixedly installed at one end of the second screw 32 outside the housing 1. The rotating handle is covered with an anti-slip rubber sleeve, which makes it easy for the operator to apply force and prevents the hand from slipping, while also preventing the operator's fingers from being worn by the screw.

[0035] Cooling assembly 4 includes a cooling plate 41 and a drive component 42, wherein: The cooling plate 41 can be moved along the first direction and installed inside the housing 1, and is located between the two sets of conveying components. The side of the cooling plate 41 near the fiber prepreg to be processed has a serpentine cooling channel, through which low-temperature coolant can be introduced to achieve the purpose of cooling. The serpentine cooling channel has a thermally conductive silicone layer on the outside, thereby improving the heat exchange efficiency.

[0036] The fixed end of the drive component 42 is installed on the outer side wall of the housing 1, and the telescopic end extends into the housing 1 and is connected to the cooling plate 41. The drive component 42 is used to drive the cooling plate 41 to reciprocate in the first direction inside the housing 1. In this way, the distance between the cooling plate 41 and the fiber prepreg to be processed can be easily adjusted by the setting of the drive component 42.

[0037] Optionally, the drive component 42 is a cylinder. Cylinders are fast, efficient, simple in structure, and easy to install and maintain.

[0038] Optionally, it also includes a stabilizer bar 43, which can be slidably mounted on the housing 1 along the first direction. One end of the stabilizer bar 43 extends into the housing 1 and is connected to the cooling plate 41. The axis of the stabilizer bar 43 is set along the first direction. That is, a through hole is opened at the top of the housing 1, and the stabilizer bar 43 is slidably mounted in the through hole. In this way, the stability of the cooling plate 41 when it moves is enhanced by the setting of the stabilizer bar 43, and it is prevented from tilting.

[0039] Optionally, a sealing sleeve is provided between the stabilizer bar 43 and the through hole, which reduces the chance of cold air leaking out of the box 1 and prevents external dust from entering the box 1.

[0040] Optionally, there are two stabilizer bars 43, which are arranged symmetrically on an axis. In this way, the stability of the cooling plate 41 during movement is further enhanced by the arrangement of two stabilizer bars 43.

[0041] Optionally, there are two cooling components 4, and the two cooling components 4 are symmetrically arranged along the plane containing the second direction and the third direction. The first direction, the second direction, and the third direction are arranged perpendicular to each other in pairs. The working temperature of the cooling plate 41 above the fiber prepreg to be treated is set to be lower than that of the cooling plate 41 below. In this way, by setting the two cooling components 4 symmetrically, the upper and lower surfaces of the fiber prepreg to be treated are cooled at the same time, which improves the cooling efficiency of the fiber prepreg to be treated. In addition, by setting the box 1, a cooling space is formed inside the box 1, which reduces external temperature interference, allowing the fiber prepreg to be treated to cool down and set quickly, significantly reducing viscosity and reducing the risk of resin being carried away during peeling.

[0042] refer to Figure 4 The separating assembly 5 includes a take-up roller 51 and a take-up motor 52, wherein: The take-up roller 51 is rotatably mounted on the outer side wall of the housing 1. The take-up roller 51 is used to take up the release film. In this way, by setting the take-up roller 51, the take-up roller 51 rotates, so that the release film connected to the take-up roller 51 is wound on the take-up roller 51, and at the same time, the purpose of automatically peeling off the release film from the fiber prepreg to be processed is achieved.

[0043] The take-up motor 52 is mounted on the housing 1. The take-up motor 52 is used to drive the take-up roller 51 to rotate. In this way, choosing a motor as the power source can provide stable rotational power to the take-up roller 51 and is easy to control.

[0044] It also includes a connecting block 53 and a protective roller 54, wherein: There are two connecting blocks 53, both of which are installed on the outer wall of the box 1 and located at the discharge port 13, and the two connecting blocks 53 are spaced apart along the second direction.

[0045] The protective roller 54 is rotatably mounted between the two connecting blocks 53. In this way, the protective roller 54 prevents the release film from rubbing against the edge of the outlet 13 during the peeling process. The rotatably mounted protective roller 54 further reduces the friction between the release film and the protective roller 54. Optionally, the protective roller 54 is provided with a wear-resistant silicone layer, which further reduces the friction between it and the release film and prevents scratches from appearing on the surface of the release film.

[0046] Adjustment assembly 6 includes a mounting rod 61, an adjustment motor 62, an arc-shaped plate 63, a connecting rod 64, and a bearing, wherein: One end of the mounting rod 61 is mounted on the outer wall of the housing 1, and the other end extends in a third direction. Optionally, the mounting rod 61 can be fixedly mounted on the housing 1 or detachably mounted on the housing 1.

[0047] The adjusting motor 62 is installed on the end of the mounting rod 61 near the housing 1, and the rotating shaft of the adjusting motor 62 is set along the second direction.

[0048] One end of the arc-shaped plate 63 is installed on the end of the mounting rod 61 away from the housing 1, and the other end is installed on the housing 1. An arc-shaped hole 631 is provided on the arc-shaped plate 63. The winding motor 52 is slidably installed on the arc-shaped plate 63. The rotating shaft of the winding motor 52 is rotatably installed in the arc-shaped hole 631. Optionally, the arc-shaped plate 63 is located between the winding motor 52 and the winding roller 51, and the distance between the winding roller 51 and the winding motor 52 is equal to the thickness of the arc-shaped plate 63. That is, the end of the winding roller 51 near the winding motor 52 is in contact with the side of the arc-shaped plate 63 near the winding roller 51, and the end of the fixed part of the winding motor 52 near the winding roller 51 is in contact with the side of the arc-shaped plate 63 near the fixed part of the winding motor 52.

[0049] One end of the connecting rod 64 is fixedly connected to the rotating shaft of the adjusting motor 62, and the other end is rotatably connected to the rotating shaft of the take-up motor 52. Thus, by setting the connecting rod 64, when the rotating shaft of the adjusting motor 62 rotates, it drives the other end of the connecting rod 64 to swing, thereby causing the take-up motor 52, which is rotatably connected to the other end of the connecting rod 64, to slide on the arc plate 63, so that the take-up roller 51 slides on the arc plate 63, thereby achieving the purpose of adjusting the vertical distance between the take-up roller 51 and the fiber prepreg to be processed, that is, achieving the purpose of adjusting the peeling angle of the separation component 5.

[0050] The bearing is installed between the connecting rod 64 and the shaft of the winding motor 52. By setting the bearing, the friction between the connecting rod 64 and the shaft of the winding motor 52 is reduced, which makes it easier for the winding motor 52 to drive the winding roller 51 to rotate.

[0051] Optionally, there are two sets of separation components 5 and two sets of adjustment components 6. The two sets of separation components 5 are installed on both sides of the discharge port 13. The two sets of separation components 5 are symmetrically arranged along the plane containing the second direction and the third direction. The two sets of adjustment components 6 are also installed on both sides of the discharge port 13. The two sets of adjustment components 6 are symmetrically arranged along the plane containing the second direction and the third direction. In this way, the upper and lower release films of the fiber prepreg to be processed can be peeled off simultaneously through the symmetrically arranged separation components 5, thereby improving the peeling efficiency.

[0052] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
