Description

Technical Field

[0001] This utility model belongs to the technical field of fiber-reinforced material manufacturing equipment, and in particular relates to a production device for long fiber-reinforced thermoplastic composite materials. Background Technology

[0002] Long-fiber reinforced thermoplastic (LFT) is a type of thermoplastic characterized by its designability, low density, high specific strength, high specific modulus, and high impact resistance. The emergence of LFT thermoplastics has posed a significant challenge to aluminum alloys and fiber-reinforced thermosetting composites, and LFT thermoplastics are gradually becoming the mainstream material for manufacturing automotive parts.

[0003] Existing equipment is not convenient for processing long fibers as a whole, which may cause the long fibers to bend and entangle inside the equipment, affecting processing. At the same time, it is not convenient to stir the materials, and some dried and clumped materials are not easy to separate. Furthermore, the residual heat after the long fibers are processed may burn the workers. Therefore, we propose a production device for long fiber reinforced thermoplastic composite materials. Utility Model Content

[0004] The purpose of this invention is to provide a production device for long fiber reinforced thermoplastic composite materials. By using rollers, it solves the problems of existing equipment, which is not convenient for handling long fibers as a whole, which may cause the long fibers to bend and entangle when entering the equipment, affecting processing. At the same time, it is not convenient for stirring the materials, and some dried and clumped materials are not easy to separate. In addition, the residual heat after the long fibers are processed may burn the workers.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a production device for long fiber reinforced thermoplastic composite materials, comprising a production machine body, a transmission cavity and a processing cavity formed on the inner wall of the production machine body, a chute formed on the inner wall of the production machine body, a collecting plate slidably connected to the inner wall of the chute, a stirring mechanism inside the production machine body, the stirring mechanism including a feeding box, the outer wall of the feeding box being fixedly connected to the inner wall of the production machine body, a filter plate slidably connected to the inner wall of the feeding box, a discharge port fixedly connected to the bottom of the feeding box, and a transmission mechanism formed on the outer wall of the production machine body, the transmission mechanism including a motor base, the outer wall of the motor base being fixedly connected to the outer wall of the production machine body, and a motor fixedly connected to the outer wall of the motor base.

[0007] Through the above technical solution, the filter plate can filter out the part of the material that has been dried and solidified, and the collection plate can collect the excess dripping material, reducing waste.

[0008] Furthermore, a number of fixing blocks are fixedly connected to the outer wall of the main body of the production machine, a fixing plate is rotatably connected to the inner wall of the fixing blocks, and bolts are slidably connected to the inner wall of the fixing plate.

[0009] The above technical solution allows for the replacement and maintenance of rollers by loosening the bolts, making it convenient for users to install or disassemble the equipment.

[0010] Furthermore, a roller is rotatably connected to the outer wall of the bolt, a nut is rotatably connected to the outer wall of the end of the bolt away from the roller, a spring is fixedly connected to the outer wall of the fixing plate, and the outer wall of the spring is fixedly connected to the outer wall.

[0011] Through the above technical solution, the spring can tighten the roller, keep it in close contact with the long fiber at all times, and fix long fibers of different sizes.

[0012] Furthermore, a number of heating plates are fixedly connected to the inner wall of the main body of the production machine, and an installation hole is opened on the outer wall of the main body of the production machine near the fixed block, and a fan is fixedly connected to the inner wall of the installation hole.

[0013] Through the above technical solution, the long fibers will be baked and solidified when passing through the heating plate, and the fan can cool down the long fibers to prevent the user from being burned by excessive residual heat.

[0014] Furthermore, a drive shaft is fixedly connected to the bottom output end of the motor via a coupling, and several pulleys are fixedly connected to the outer wall of the drive shaft. Several stirring blades are fixedly connected to the outer wall of the end of the drive shaft away from the pulleys.

[0015] The above technical solution uses the rotating agitator blades to disrupt the materials inside the discharge box, thus homogenizing the materials.

[0016] Furthermore, a second belt is driven to the outer wall of the inner pulley, a belt is driven to the outer wall of the outer pulley, and a second pulley is driven to the inner wall of the end of the second belt away from the pulley.

[0017] Through the above technical solution, the rotation of belt two drives the rotation of belt pulley, and the rotation of belt pulley drives the rotation of belt pulley two.

[0018] Furthermore, a plurality of fixed shafts are rotatably connected to the inner wall of the main body of the production machine near the second pulley. The outer wall of the upper fixed shaft is fixedly connected to the inner wall of the second pulley. A gear is fixedly connected to the outer wall of the fixed shaft. The outer wall of the upper gear meshes with the outer wall of the lower gear. The inner wall of the main body of the production machine near the fan is rotatably connected to the second fixed shaft. A third pulley is fixedly connected to the outer wall of the second fixed shaft. The outer wall of the third pulley is rotatably connected to the inner wall of the belt.

[0019] Through the above technical solution, the rotation of the second pulley drives the rotation of the fixed shaft, causing the upper gear to rotate, and the rotation of the upper gear drives the rotation of the lower gear.

[0020] Furthermore, a gear three is fixedly connected to the outer wall of the fixed shaft two, a fixed shaft three is fixedly connected to the outer wall of the fan, and a gear three is fixedly connected to the outer wall of the fixed shaft three, with the outer wall of the gear three meshing with the outer wall of the gear two.

[0021] The above technical solution uses a fixed shaft to rotate, which drives a fan to rotate and generate airflow to cool the cured long fibers.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model features a feeding box. When the equipment is needed, the user injects the material into the feeding box. The filter plate can separate the clumps of material, and long fibers are inserted into the device from the left side opening. The rollers ensure that the long fibers enter the device in a straight line. At the same time, long fibers of different sizes can be fixed, which can adjust the long fibers and prevent them from getting tangled in the device. The long fibers can also be automatically transported into the device without manual operation, reducing the user's operating pressure.

[0024] 2. This utility model incorporates a second belt. During operation, the rotation of the second belt drives the rotation of the second pulley, which in turn rotates multiple transmission wheels. The rotation of these transmission wheels automatically feeds the long fibers into the device. The rotation of the belt drives the rotation of the second fixed shaft, which in turn drives the rotation of the third gear, causing the entire device to rotate and generating airflow. The material drips from the outlet onto the surface of the long fibers, thus achieving the goal of stirring the material and preventing uneven material distribution that could lead to low work efficiency. It also filters out dried and clump-forming materials and allows for cooling after the long fibers have solidified, preventing burns from excessive residual heat.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
