Description

Technical Field

[0001] This application relates to the field of composite material preparation technology, and in particular to a device for fixing and impregnating long glass fiber reinforced plastic filaments. Background Technology

[0002] The published patent with authorization announcement number CN220113774U discloses a long glass fiber reinforced plastic filament fixing and impregnation device. The device consists of an impregnation container fixedly mounted on a mounting frame. The impregnation container has mounting grooves on both sides. A traction device is mounted on the impregnation container, an electromagnet is fixedly mounted in the mounting groove, and a contact plate is fixedly mounted on the output end of the electromagnet. A crossbar passes through the mounting groove and is located on the side of the mounting groove closest to the contact plate. A U-shaped frame is fixedly mounted on the crossbar and located inside the impregnation container. A pressure roller is fixedly mounted on the U-shaped frame and located on the side of the U-shaped frame away from the crossbar. A spring assembly is mounted in the mounting groove. The electromagnet drives the crossbar to move downwards, and the movement of the crossbar causes the pressure roller on the U-shaped frame to press down on the filaments in the impregnation container, thereby ensuring the filaments are fully impregnated with the adhesive and improving the product's yield.

[0003] The device in the aforementioned patent improves the product yield by fully impregnating the fibers. However, the device does not cool the fibers in time after impregnation, which may prevent them from quickly forming a stable plastic state, resulting in poor impregnation effect and reducing the practicality of the device.

[0004] Therefore, this application proposes a device for fixing and impregnating long glass fiber reinforced plastic filaments. Utility Model Content

[0005] This application proposes a long glass fiber reinforced plastic filament fixing and impregnation device to solve the problems mentioned in the background art. This long glass fiber reinforced plastic filament fixing and impregnation device, by setting up a cooling mechanism, fan, cooler, air supply pipe, cooling pipe, distribution pipe, cooling hole and cooling box, can quickly cool the impregnated filaments, avoiding the problem of poor plasticity caused by the filaments not being cooled in time after impregnation, and greatly improving the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A long glass fiber reinforced plastic filament fixing and impregnation device includes a housing, a supporting structure at the bottom of the housing, a conveying mechanism inside the housing, a preheating structure inside the conveying mechanism, a lifting mechanism inside the housing, an impregnation structure at the bottom of the lifting mechanism, a cooling mechanism on the inner side of the housing, the cooling mechanism including a cooling box fixedly connected to the inner side of the housing, a fan mounted on the top of the housing, an air supply pipe fixedly connected to the air outlet of the fan, a cooler mounted on the top of the housing, the air supply pipe passing through the interior of the cooler and then out of the cooler, the air supply pipe extending into the interior of the housing, multiple cooling pipes fixedly connected to the top of the interior of the cooling box, the cooling pipes being connected by a branch pipe, multiple cooling holes at the bottom of the cooling pipes, and an opening on the surface of the housing.

[0008] In a preferred embodiment, the support structure includes support legs, which are fixedly connected to the four bottom corners of the device housing, and a contact plate is fixedly connected to the top of the support legs;

[0009] The support legs provide overall support for the device, and the contact plate increases the contact area between the support legs and the ground, making the device more stable and thus improving its practicality.

[0010] In a preferred embodiment, each contact plate is equipped with a friction pad at its bottom;

[0011] By installing friction plates at the bottom of the contact plate, the friction between the contact plate and the ground can be increased, making the device less prone to movement during operation and thus improving its practicality.

[0012] In a preferred embodiment, the conveying mechanism includes a first motor, which is fixedly connected to one end of the outer casing of the device. The output end of the first motor extends into the interior of the device casing. A rotating rod is fixedly connected to the output end of the first motor, and the other side of the rotating rod is rotatably connected to the device casing. A conveying roller is fixedly connected to the outside of the rotating rod.

[0013] The device uses a motor to drive a rotating rod, which in turn drives a conveying roller to rotate, thus conveying the fibers. The device also has two sets of conveying mechanisms inside its casing, which ensures that the fibers are conveyed smoothly, thereby improving the device's practicality.

[0014] In a preferred embodiment, the preheating structure includes a placement groove, which is formed inside the rotating rod, and a heating wire is placed inside the placement groove;

[0015] By activating the heating wire, the temperature of the conveying roller can be increased, allowing the fibers to be preheated during fiber conveying and reaching a suitable impregnation temperature, thereby improving the practicality of the device.

[0016] In a preferred embodiment, the lifting mechanism includes a second motor, which is fixedly connected to the top of the device housing. The output end of the second motor extends into the interior of the device housing. A threaded rod is fixedly connected to the output end of the second motor. A concave rod is threadedly connected to the outer side of the threaded rod. A guide groove is provided on one side of the inner wall of the concave rod, and one side of the concave rod is slidably connected to the guide groove. A pressure roller is rotatably connected to the inner side of the bottom end of the concave rod.

[0017] The screw rod is driven to rotate by the No. 2 motor. Under the guidance of the guide groove, the concave rod is raised and lowered, which in turn drives the pressure roller to rise and fall, thereby pressing the fiber downward and making it completely immersed in the solution. This ensures that the fiber is fully impregnated, thus improving the practicality of the device.

[0018] In a preferred embodiment, the impregnation structure includes an impregnation tank, which is fixedly connected to the bottom of the inner part of the device housing, and the top surface of the impregnation tank is chamfered on the inner side.

[0019] The impregnation solution is placed in an impregnation tank. A chamfer is made on the top surface of the impregnation tank to prevent the filaments from being pressed against the right-angled edge during the pressing process, thus improving the practicality of the device.

[0020] In a preferred embodiment, the openings are located on the left and right sides of the device housing and need to be flush with each other.

[0021] The fiber enters and exits through the opening. Since the opening is parallel to the top of the conveyor roller, the openings on the left and right sides must be kept flush to ensure that the fiber is kept horizontal during conveying, thus protecting the fiber and improving the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] 1. This long glass fiber reinforced plastic filament fixing and impregnation equipment, by setting up a cooling mechanism, fan, cooler, air supply pipe, cooling pipe, distribution pipe, cooling holes and cooling box, can quickly cool the impregnated filaments. After the fan is started, the air supply pipe delivers air to the cooler, where the cooler cools the air. After cooling, the air is delivered to the cooling pipe and then distributed through the distribution pipe. Finally, multiple cooling holes are used to cool the filaments. This mechanism avoids the problem of poor plasticity caused by the filaments not being cooled in time after impregnation, and greatly improves the practicality of the device.

[0024] 2. This long glass fiber reinforced plastic filament fixing and impregnation equipment can preheat the filaments by setting a preheating structure, a placement tank and a heating wire, which greatly improves the practicality of the device. Attached Figure Description

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Reference Figure 1 , 34. A long glass fiber reinforced plastic filament fixing and impregnation device includes a device housing 1, a support structure 2 is provided at the bottom of the device housing 1, the support structure 2 includes support legs 21, and the support legs 21 are fixedly connected to the four bottom corners of the device housing 1, and a contact plate 22 is fixedly connected to the top of the support legs 21; the support legs 21 can provide support for the entire device, and the contact plate 22 can increase the contact area between the support legs 21 and the ground, making the device more stable, thereby improving the practicality of the device.

[0033] Reference Figure 3 Each contact plate 22 has a friction plate 221 installed at its bottom. By installing the friction plate 221 at the bottom of the contact plate 22, the friction between the contact plate 22 and the ground can be increased, making the device less likely to move during operation, thereby improving the practicality of the device.

[0034] Reference Figure 1-4 The device housing 1 is equipped with a conveying mechanism 3. The conveying mechanism 3 includes a primary motor 31, which is fixedly connected to one end of the outer casing of the device housing 1. The output end of the primary motor 31 extends into the interior of the device housing 1. A rotating rod 32 is fixedly connected to the output end of the primary motor 31, and the other side of the rotating rod 32 is rotatably connected to the device housing 1. A conveying roller 33 is fixedly connected to the outside of the rotating rod 32. The primary motor 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the conveying roller 33 to rotate, thereby conveying the fibers. The device housing 1 has two sets of conveying mechanisms 3, which can ensure that the fibers remain smooth during the conveying process, thereby improving the practicality of the device.

[0035] Reference Figure 2 The conveying mechanism 3 is equipped with a preheating structure 4, which includes a placement groove 41 and is located inside the rotating rod 32. A heating wire 42 is placed inside the placement groove 41. By activating the heating wire 42, the temperature of the conveying roller 33 can be increased. During fiber conveying, the fibers can be preheated in advance so that they reach a suitable impregnation temperature, thereby improving the practicality of the device.

[0036] Reference Figure 1 , 3In addition to the above, the device housing 1 is equipped with a lifting mechanism 5. The lifting mechanism 5 includes a second motor 51, which is fixedly connected to the top of the device housing 1. The output end of the second motor 51 extends into the interior of the device housing 1. A threaded rod 52 is fixedly connected to the output end of the second motor 51. A concave rod 53 is threadedly connected to the outside of the threaded rod 52. A guide groove 54 is opened on one side of the inner wall of the device housing 1. One side of the concave rod 53 is slidably connected to the guide groove 54. A pressure roller 55 is rotatably connected to the inner side of the bottom end of the concave rod 53. The second motor 51 drives the threaded rod 52 to rotate. Under the guidance of the guide groove 54, the concave rod 53 is raised and lowered, which in turn drives the pressure roller 55 to rise and lower, thereby pressing the fiber downward to completely immerse it in the solution and ensure that the fiber is fully impregnated, thus improving the practicality of the device.

[0037] Reference Figure 1 , 3 The bottom of the lifting mechanism 5 is provided with an impregnation structure 6, which includes an impregnation tank 61. The impregnation tank 61 is fixedly connected to the bottom of the inner part of the device housing 1. A chamfer 62 is provided on the inner side of the top surface of the impregnation tank 61. The impregnation solution is placed in the impregnation tank 61. The chamfer 62 on the top surface of the impregnation tank 61 can prevent the fibers from being pressed on the right-angled edge during the downward pressing process, thus improving the practicality of the device.

[0038] Reference Figure 1 , 3 4. A cooling mechanism 7 is provided on the inner side of the device housing 1. The cooling mechanism 7 includes a cooling box 77, and the cooling box 77 is fixedly connected to the inner side of the device housing 1. A fan 71 is installed on the top of the device housing 1. An air supply pipe 73 is fixedly connected to the air outlet of the fan 71. A cooler 72 is installed on the top of the device housing 1. The air supply pipe 73 passes into the interior of the cooler 72 and then out of the cooler 72. The air supply pipe 73 passes through the interior of the device housing 1. Multiple cooling pipes 74 are fixedly connected to the top of the interior of the cooling box 77. A branch pipe 75 is connected between the cooling pipes 74. Multiple cooling holes 76 are opened at the bottom of the cooling pipes 74.

[0039] Reference Figure 1 , 4 The device housing 1 has openings 8 on its surface. The openings 8 are located on the left and right sides of the device housing 1 and need to be kept flush. The fibers are fed in and out through the openings 8. Since the openings 8 are parallel to the top of the conveying roller 33, the openings 8 on the left and right sides need to be kept flush to ensure that the fibers are kept horizontal during conveying and to protect the fibers, thereby improving the practicality of the device.

[0040] Working principle: During operation, the device uses a first motor 31 to drive a rotating rod 32, which in turn drives a conveying roller 33 to rotate, thus conveying the fibers. The device housing 1 has two sets of conveying mechanisms 3 inside, ensuring smooth fiber transport. Activating the heating wire 42 increases the temperature of the conveying roller 33, preheating the fibers to a suitable impregnation temperature. A second motor 51 drives a threaded rod 52, which, guided by a guide groove 54, causes the concave rod 53 to rise and fall, ultimately driving the pressure roller 55. The system is raised and lowered to press the fibers downwards, ensuring they are fully immersed in the solution. The solution is then placed in an impregnation tank 61. A chamfer 62 is provided on the top surface of the impregnation tank 61 to prevent the fibers from being pressed against the right-angled edge during the downward process and thus avoiding damage. After the fan 71 is started, air is delivered to the cooler 72 through the air pipe 73. The cooler 72 cools the air, and the cooled air is then delivered to the cooling pipe 74. The air is then distributed through the diversion pipe 75 and finally cooled using multiple cooling holes 76. The air is then transported to the outside for storage through the opening 8.

[0041] The fiber enters and exits through the opening 8. Since the opening 8 is parallel to the top of the conveying roller 33, the openings 8 on the left and right sides must be kept flush to ensure that the fiber is kept horizontal during conveying and to protect the fiber. The support leg 21 can support the whole device. The contact plate 22 can increase the contact area between the support leg 21 and the ground, making the device more stable. By installing a friction plate 221 at the bottom of the contact plate 22, the friction between the contact plate 22 and the ground can be increased, making the device less likely to move during operation.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
