Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite material preparation equipment technology, and in particular to a liftable automatic protection device suitable for the production of prepreg composite materials. Background Technology
[0002] In the preparation of composite materials (prepregs), fibers and resin films are hot-pressed by multiple pairs of rotating (mostly counter-rotating) heated steel rollers, allowing the resin to penetrate into the fibers and fully bond. Human intervention is unavoidable during production, such as feeding materials, observing product production status, measuring temperature, venting, and cleaning equipment. The heating, pressurizing, and rotating steel rollers can easily cause personnel injury. Furthermore, foreign objects falling onto the surface of the material being produced and being introduced into the steel rollers can also damage the equipment. Traditional fixed protective plates, due to their small and fixed spacing between the upper and lower plates, are not conducive to certain operations during production. Additionally, the intrusion of external elements (personnel or foreign objects) under special circumstances cannot be prevented in time, which can also cause personnel or equipment injury.
[0003] Therefore, there is an urgent need for a liftable automatic protection device suitable for the production of prepreg composite materials. This device should not only be able to automatically detect intrusions (personnel or foreign objects) during equipment operation, but also provide automatic protection when intrusions occur, thus protecting the safety of personnel and equipment. Utility Model Content
[0004] The purpose of this invention is to provide a liftable automatic protective device suitable for the production of prepreg composite materials, in order to solve the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a liftable automatic protective device suitable for the production of prepreg composite materials, including a lower plate fixedly installed on the lower part of one side of the production equipment, an upper plate provided above the lower plate, a control component for controlling the lifting and lowering of the upper plate installed at the end of the upper plate away from the lower plate, the control component being electrically connected to a control cabinet, and light gratings for detecting external intrusion installed on both sides between the upper plate and the lower plate, the light gratings being electrically connected to the control cabinet.
[0006] Preferably, the control component includes a connecting frame, which is connected to the upper plate via a plurality of screws. The end of the connecting frame away from the upper plate is fixedly connected to the telescopic end of a cylinder, and the fixed end of the cylinder is fixedly connected to the production equipment.
[0007] Preferably, both ends of the screw are connected to the connecting frame and the upper plate respectively by fixing nuts.
[0008] Preferably, the control cabinet is electrically connected to the cylinder.
[0009] Preferably, the upper plate and the lower plate are arranged correspondingly.
[0010] Preferably, the upper plate has a plurality of holes.
[0011] Preferably, the control cabinet is equipped with an alarm, a speed controller, a linkage button, an up button, and a down button.
[0012] The present invention discloses the following technical effects:
[0013] When the production equipment is running, the grating detects an intrusion and sends a signal to the control cabinet. The control cabinet then sends a signal to the control component, which moves the upper plate closer to the lower plate. This allows the invention to not only automatically detect intrusions during equipment operation but also to automatically protect against intrusions, ensuring the safety of personnel and production equipment. Attached Figure Description
[0014] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] The components include: 1. Connecting frame; 2. Upper plate; 3. Lower plate; 4. Cylinder; 5. Screw; 6. Grating; 7. Control cabinet; 8. Fixing nut. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] Reference Figure 1This utility model discloses a liftable automatic protection device suitable for the production of prepreg composite materials, including a lower plate 3 fixedly installed on the lower part of one side of the production equipment, an upper plate 2 provided above the lower plate 3, a control component for controlling the lifting of the upper plate 2 is installed at the end of the upper plate 2 away from the lower plate 3, the control component is electrically connected to a control cabinet 7, and light grids 6 for detecting external intrusion are respectively installed on both sides between the upper plate 2 and the lower plate 3, the light grids 6 are electrically connected to the control cabinet 7.
[0020] When the production equipment is running, if the grating 6 detects an intrusion, it sends a signal to the control cabinet 7. The control cabinet 7 then sends a signal to the control component, which moves the upper plate 2 closer to the lower plate 3. This allows the invention to not only automatically detect intrusions during equipment operation but also automatically protect against intrusions, ensuring the safety of personnel and production equipment.
[0021] The scheme is further optimized. The control component includes a connecting frame 1, which is connected to the upper plate 2 via several screws 5. The end of the connecting frame 1 away from the upper plate 2 is fixedly connected to the telescopic end of a cylinder 4, and the fixed end of the cylinder 4 is fixedly connected to the production equipment. The telescopic end of the cylinder 4 drives the connecting frame 1 to rise and fall, and the connecting frame 1 drives the upper plate 2 to rise and fall.
[0022] In a further optimized design, both ends of the screw 5 are connected to the connecting frame 1 and the upper plate 2 respectively via fixing nuts 8. The fixing nuts 8 facilitate the installation and removal of the upper plate 2.
[0023] The design was further optimized by electrically connecting control cabinet 7 to cylinder 4, enabling control cabinet 7 to control the operation of cylinder 4.
[0024] The design was further optimized, with the upper plate 2 and lower plate 3 positioned vertically in a corresponding manner. The lifting and lowering of the upper plate 2 not only facilitates the passage of production materials between the upper plate 2 and lower plate 3, but also effectively protects the production equipment, thus safeguarding personnel and equipment.
[0025] The design was further optimized by adding several holes to the upper plate 2. These holes facilitate observation of the material's condition during production on the equipment. The holes can be square, round, or other shapes.
[0026] The design has been further optimized, with an alarm, speed controller, linkage button, up button, and down button installed on control cabinet 7.
[0027] The speed regulator allows for easy adjustment of the lifting speed of the upper plate 2; the alarm is used for alarm purposes; when the linkage button is activated, the light grating 6 can automatically brake the equipment for protection when it detects external intrusion; the up and down buttons are used for manual control of the lifting of the upper plate 2.
[0028] Work process:
[0029] Before production, switch control cabinet 7 to single-action mode and manually raise the upper plate 2 to increase the gap between the upper plate 2 and the lower plate 3, so that production materials can pass through the middle.
[0030] After production begins, manually lower the upper plate 2 to reduce the gap between the upper plate 2 and the lower plate 3 to the required protection height. Set the control cabinet 7 to linkage mode. In this mode, the light grating 6 will be activated. When it detects the intrusion of external (personnel or foreign objects), it can automatically brake the production equipment for protection, protecting personnel and production equipment.
[0031] After production is completed, switch control cabinet 7 to single-action mode, manually raise the upper plate 2 to increase the gap between the upper plate 2 and the lower plate 3, so that the remaining production materials can pass through and the production equipment can be cleaned.
[0032] This invention allows for quick adjustment of the distance between the upper plate 2 and the lower plate 3, making it easy to operate; at the same time, the grating 6's grating sensing function enables automatic control of emergency braking of production equipment.
