Description

Technical Field

[0001] This utility model relates to the technical field of joint identification and detection devices, specifically a prepreg joint identification and detection device. Background Technology

[0002] Due to the inherent characteristics of the raw materials (fabric), each roll of prepreg in the production of composite fabrics is only 100-200 meters long. Prepreg production is a streamlined roll-to-roll process; therefore, when changing rolls, the fabric rolls need to be overlapped. Currently, this overlap is achieved through sewing or double-sided adhesive. After the overlapped fabric undergoes a heat-pressing prepreg treatment, it is processed into prepreg, which is then wound up by a winding mechanism. To improve production and storage efficiency, a single roll of prepreg is made by overlapping multiple single rolls of fabric.

[0003] Prepreg cannot be used properly in subsequent processes due to overlaps and sewing threads (tape) at the fabric seams. It needs to be identified and removed. However, currently, identification and marking are done manually, which can lead to some wrinkles and defects being missed due to human error during production, affecting subsequent use. Therefore, the existing technology needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a prepreg joint identification and detection device, which solves the problem that manual identification is prone to oversight and affects subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prepreg joint identification and detection device, comprising a frame, a prepreg roll mounted on the upper left side of the frame, a joint identification mechanism mounted on the frame, a traction device mounted on the upper right side of the frame, the joint identification mechanism comprising a frame, two symmetrically distributed frames mounted on the upper end of the frame, each frame having a mounting bearing assembly installed inside, a lower support roller connected between the two mounting bearing assemblies, displacement sensors mounted on opposite sides of the two frames, a guide cylinder assembly mounted on the output end of the displacement sensor, a self-aligning bearing assembly mounted on the upper end of the output end of the guide cylinder assembly, an upper floating roller mounted inside the two self-aligning bearing assemblies, a connecting frame fixedly connected to the outer side of the frame, and a positioning rod fixedly mounted on the upper end of the frame.

[0006] Preferably, the connecting frame is slidably connected to the positioning rod, and the connecting frame is in slidable contact with the equipment frame, and the positioning rod can position the connecting frame.

[0007] Preferably, the upper floating roller is located directly above the lower support roller, and a guide roller is installed between the two frames to guide the material.

[0008] Preferably, an installation mechanism is provided between the connector identification mechanism and the equipment frame. The installation mechanism includes a limiting frame, the upper end of the equipment frame is slidably connected to the limiting frame, the lower end of the limiting frame is fixedly connected to a moving plate, the inside of the equipment frame is fixedly connected to a guide pin, and the outside of the guide pin is provided with a spring, so that the guide pin can guide the moving plate.

[0009] Preferably, the limiting frame is slidably connected to the connecting frame, and the limiting frame is slidably connected to the positioning rod. The limiting frame can limit the position of the frame through the connecting frame.

[0010] Preferably, the movable plate is slidably connected to the equipment frame and the guide pin, and the movable plate can drive the limiting frame to move.

[0011] Preferably, one end of the spring is fixedly connected to the movable plate, and the other end of the spring is fixedly connected to the equipment frame. The spring can automatically reset the movable plate through its elastic force.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adds a floating roller, displacement sensor and guide cylinder assembly to the frame. During the material release process, the fabric moves between the floating roller and the lower support roller. The joint thickness is greater than the fabric thickness, which can drive the floating roller to move upward. The displacement sensor can then detect this movement, eliminating the need for manual identification and improving identification accuracy to avoid affecting later use.

[0014] 2. By adding a movable plate, a limiting frame, and a spring to the equipment frame, the limit frame on the movable plate can be slid to the outside of the connecting frame of the machine frame by the elastic force of the spring when the connector identification mechanism needs to be installed, thus completing the installation and making the connector identification mechanism easier to use.

[0024] Please see Figure 1 , Figure 4 , Figure 5 An installation mechanism 6 is provided between the connector identification mechanism 2 and the equipment frame 4. The installation mechanism 6 includes a limiting frame 61. The upper end of the equipment frame 4 is slidably connected to the limiting frame 61, and the lower end of the limiting frame 61 is fixedly connected to a moving plate 62. The inside of the equipment frame 4 is fixedly connected to a guide pin 63, and the outside of the guide pin 63 is provided with a spring 64. The guide pin 63 can guide the moving plate 62. The limiting frame 61 is slidably connected to the connecting frame 29 and the positioning rod 5. The limiting frame 61 can limit the frame 21 through the connecting frame 29.
